Although environmentally aged MNPs predominate, their developmental toxicity remains poorly understood. We demonstrate that both pristine and aged polystyrene nanoplastics (PSNPs) induce abnormal lipid accumulation and impair early development in zebrafish larvae. Lipidomics revealed aged PSNPs significantly increased triglycerides via disrupted glycerophospholipid metabolism. Mechanistically, aged PSNPs did not alter LC3-II/LC3-I ratios but upregulated RAB7 and p62 while downregulating lysosomal biogenesis regulator TFEB. They also reduced ATG5, essential for autophagosome formation via LC3 lipidation. These molecular alterations, together with lysosomal inhibition assays, functionally support lysosomal dysfunction as a key constraint on lipophagy. This impairment inhibits lipid utilization, promotes accumulation, and disrupts development. Critically, aged PSNPs caused stronger disruption than pristine particles despite both interfering with lipophagy. Our study provides mechanistic insights into the developmental toxicity of UV-aged PSNPs in zebrafish, highlighting the importance of considering aging-related changes in nanoplastic risk evaluation. SYNOPSIS: Aged nanoplastics exacerbate developmental toxicity in zebrafish by suppressing lipophagy to drive lipid accumulation, underscoring ecological risks in aquatic systems."

"abstract_text": "ID: 40065324\nTitle: Lysosomal acidification impairment in astrocyte-mediated neuroinflammation.\nAbstract: Astrocytes are a major cell type in the central nervous system (CNS) that play a key role in regulating homeostatic functions, responding to injuries, and maintaining the blood-brain barrier. Astrocytes also regulate neuronal functions and survival by modulating myelination and degradation of pathological toxic protein aggregates. Astrocytes have recently been proposed to possess both autophagic activity and active phagocytic capability which largely depend on sufficiently acidified lysosomes for complete degradation of cellular cargos. Defective lysosomal acidification in astrocytes impairs their autophagic and phagocytic functions, resulting in the accumulation of cellular debris, excessive myelin and lipids, and toxic protein aggregates, which ultimately contributes to the propagation of neuroinflammation and neurodegenerative pathology. Restoration of lysosomal acidification in impaired astrocytes represent new neuroprotective strategy and therapeutic direction. In this review, we summarize pathogenic factors, including neuroinflammatory signaling, metabolic stressors, myelin and lipid mediated toxicity, and toxic protein aggregates, that contribute to lysosomal acidification impairment and associated autophagic and phagocytic dysfunction in astrocytes. We discuss the role of lysosomal acidification dysfunction in astrocyte-mediated neuroinflammation primarily in the context of neurodegenerative diseases along with other brain injuries. We then highlight re-acidification of impaired lysosomes as a therapeutic strategy to restore autophagic and phagocytic functions as well as lysosomal degradative capacity in astrocytes. We conclude by providing future perspectives on the role of astrocytes as phagocytes and their crosstalk with other CNS cells to impart neurodegenerative or neuroprotective effects."

Mesenchymal stem cell-derived nanovesicle-poly(lactic-coglycolic acid) nanoparticles (MSC-PLGA-NPs) were prepared via sonication-loading. Blood-brain barrier (BBB) penetration was evaluated using in vitro transwell models and in vivo mouse models. Lysosomal function, autophagy, pathological protein clearance, and anti-inflammatory effects were assessed using various cellular and molecular biology techniques. MSC-PLGA-NPs demonstrated 2.3-fold higher BBB penetration efficiency compared to PLGA alone. In a chloroquine(CQ)-induced lysosomal injury model and mice model, they effectively restored lysosomal pH, enhanced autophagy (reducing LC3-II/I ratio by 0.4-fold and p62 expression by 52%), cleared amyloid precursor protein (APP) and phosphorylated tau (p-tau) proteins, and inhibited IL-6 and TNF-\u03b1 without hepatorenal toxicity. These results demonstrate that MSC-PLGA-NPs, a novel multifunctional nanoparticle platform, synergistically integrates the BBB penetration capability of MSC-NVs and the lysosomal acidification function of PLGA. The synergistic combination represents a pioneering \"delivery-repair-clearance\" integrated strategy for AD therapy. Offering significant advantages over single-component approaches, MSC-PLGA-NPs provide a promising preclinical candidate and new insight into lysosome-targeted nanomedicines for neurodegenerative diseases."

Nanoparticles are considered promising therapeutic candidates for AD owing to their drug-loading capacity. This study introduces an engineered cell membrane coating strategy to enhance nanoparticle functionality in targeting efficiency and susceptivity to immune clearance. We developed an engineered biomimetic nanodrug delivery system by modifying nanoparticles with Gas6-overexpressing neural stem cell membranes for improving microglia targeting, pro-phagocytic properties and immunomodulatory effects, constructing a composite system designated as Gas6-NV-NPs. The system employs poly(lactic-co-glycolic acid) (PLGA) as a carrier to coencapsulate Rapamycin (RAP) and nicotinamide riboside (NR) (referred to as NPs), while leveraging Gas6 protein to specifically bind microglial surface receptors, enabling precise targeting of AD pathological regions. Our findings demonstrated that Gas6-NV-NPs restored lysosomal acidification in microglia, enhanced microglial phagocytic clearance of amyloid-\u03b2 (A\u03b2), and reinstated the anti-inflammatory phenotype in BV2 microglial cells.

Conjugation of ATG8s to single membranes (CASM) is a noncanonical LC3\u2011lipidation pathway activated by various stressors, distinct from canonical autophagy. We previously showed that TBT reduces lysosomal acidity and inhibits autophagy in SH-SY5Y cells. Furthermore, we observed TBT-induced LC3-II accumulation, which was reduced by bafilomycin A1, and tubular LC3-positive structures as hallmarks of CASM. In this study, we investigated whether TBT activates CASM. TBT (700\u00a0nM) induced LC3-II accumulation, which was completely blocked by bafilomycin A1 in SH-SY5Y and HeLa cells. Unlike autophagy, TBT induced LC3-II accumulation even under class III PI3K inhibition by wortmannin and in FIP200-knockout cells. Salmonella effector protein SopF, which inhibits V-ATPase-ATG16L1 association required for CASM, inhibited TBT-induced LC3-II accumulation. In FIP200-knockout cells, TBT induced LC3 accumulation on lysosomes, the primary CASM target. TBT also promoted nuclear translocation of transcription factor EB (TFEB) in a SopF-sensitive manner. Together, these results identify CASM as a lysosomal stress response to TBT, induced via the V-ATPase-ATG16L1 axis, leading to TFEB activation. This mechanism provides a toxicological framework for understanding xenobiotic-induced lysosomal adaptations."

Consequently, the toxicology of such particles has emerged as a pivotal research interests in recent years. In this study, NP was synthesized successfully with an average particle size of 100\u00a0nm using a emulsion polymerization method as model particles. Following co-incubation of IEC-6 cells with NP for 24-168\u00a0h, a notable inhibition of cell viability and proliferation was observed. The significant activation of autophagy and a concomitant blockage of autophagic flux in IEC-6 cells after 24-72\u00a0h of co-incubation with NP were unveiled by transmission electron microscopy, western blotting, and double-fluorescent autophagy analysis. A significant increase in the number of lysosomes and an increase in the expression of hydrolase CTSB were detected, indicating dysregulation of lysosomal function. The subsequent transcriptomic and metabolomics analyses, coupled with the observation of activated lysosomes and the RIPK1-RIPK3-MLKL/PYGL pathway, led us to posit that the blockade of autophagy and lysosomal dysfunction, culminating in lysosomal membrane permeabilization (LMP) induced necroptosis, constitutes one of the mechanisms contributing to the cytotoxicity of NP.

This study found that nano-plastics may induce necroptosis in cells, and autophagy blockade and lysosomal dysfunction are prodromal manifestations."

However, antibiotic resistance has become a compelling health issue, leading to H. pylori eradication treatment failure worldwide. Additionally, the powerlessness of antibiotics against biofilms, as well as intracellular H. pylori and the long-term damage of antibiotics to the intestinal microbiota, have also created an urgent demand for antibiotic-free approaches. Herein, we describe an antibiotic-free, multifunctional copper-organic framework (HKUST-1) platform encased in a lipid layer comprising phosphatidic acid (PA), rhamnolipid (RHL), and cholesterol (CHOL), enveloped in chitosan (CS), and loaded in an ascorbyl palmitate (AP) hydrogel: AP@CS@Lip@HKUST-1. This platform targets inflammatory sites where H. pylori aggregates through electrostatic attraction. Then, hydrolysis by matrix metalloproteinases (MMPs) releases CS-encased nanoparticles, disrupting bacterial urease activity and membrane integrity. Additionally, RHL disperses biofilms, while PA promotes lysosomal acidification and activates host autophagy, enabling clearance of intracellular H. pylori. Furthermore, AP@CS@Lip@HKUST-1 alleviates inflammation and enhances mucosal repair through delayed Cu2+ release while preserving the intestinal microbiota. Collectively, this platform presents an advanced therapeutic strategy for eradicating persistent H. pylori infection without inducing drug resistance."

Targeting lysosomal functions with nanomaterials, such as DNA nanostructures (DNs), represents a rational and systematic way to control cell functionality. Here we present a versatile DNA nanostructure-based platform that can modulate a number of cellular functions depending on the concentration and surface decoration of the nanostructure. Utilizing different peptides for surface functionalization of DNs, we were able to rationally modulate lysosomal activity, which in turn translated into the control of cellular function, ranging from changes in cell morphology to modulation of immune signaling and cell death. Low concentrations of decalysine peptide-coated DNs induced lysosomal acidification, altering the metabolic activity of susceptible cells. In contrast, DNs coated with an aurein-bearing peptide promoted lysosomal alkalization, triggering STING activation. High concentrations of decalysine peptide-coated DNs caused lysosomal swelling, loss of cell-cell contacts, and morphological changes without inducing cell death. Conversely, high concentrations of aurein-coated DNs led to lysosomal rupture and mitochondrial damage, resulting in significant cytotoxicity. Our study holds promise for the rational design of a new generation of versatile DNA-based nanoplatforms that can be used in various biomedical applications, like the development of combinatorial anti-cancer platforms, efficient systems for endolysosomal escape, and nanoplatforms modulating lysosomal pH."

To disrupt this metabolic adaptability, we herein engineer a homotypic membrane-camouflaged nanomedicine capable of hypoxia-responsive cascade drug release and enhanced tumor accumulation. The resulting nanomedicine performs a hypoxia-induced phase transition that first liberates glucose oxidase to intensify oxygen deprivation and subsequently triggers burst release of chloroquine. Such a design of self-amplified relay drug release ensures effective starvation induction and precise lysosomal alkalization, thereby shutting down lysosome-mediated nutrient recycling. In a xenograft orthotopic PDAC model, this nanomedicine achieves 9.75-fold increase in tumor accumulation, robust tumor inhibition of 92.8%, and an elevated survival rate of 80% with favorable biosafety. Collectively, our findings highlight lysosomal disruption as a therapeutic lever to potentiate starvation therapy and provide a clinically actionable nanoplatform to enhance metabolic interventions for other metabolically vulnerable malignancies."

However, this requires the use of excessive light energy to obtain good signal-to-noise ratio, which can then photobleach fluorochromes, and more worrisomely, lead to phototoxicity. Upon light excitation, noble metal nanoparticles such as silver nanoparticles (AgNPs) generate plasmons, which can then amplify excitation in direct proximity of the nanoparticle's surface and couple to the oscillating dipole of nearby radiating fluorophores, modifying their rate of emission and thus, enhancing their fluorescence. Here, we show that AgNPs fed to cells to accumulate within lysosomes enhanced the fluorescence of lysosome-targeted Alexa488-conjugated dextran, BODIPY-cholesterol, and DQ-BSA. Moreover, AgNP increased the fluorescence of GFP fused to the cytosolic tail of LAMP1, showing that metal enhanced fluorescence can occur across the lysosomal membrane. The inclusion of AgNPs in lysosomes did not disturb lysosomal properties such as lysosomal pH, degradative capacity, autophagy and autophagic flux, and membrane integrity, though AgNP seemed to increase basal lysosome tubulation. Importantly, by using AgNP, we could track lysosome motility with reduced laser power without damaging and altering lysosome dynamics. Overall, AgNP-enhanced fluorescence may be a useful tool to study the dynamics of the endo-lysosomal pathway while minimizing phototoxicity."

This leads to marked lysosomal stress and regulated necrotic cell death pathway, while free Pc causes moderate oxidative stress with reversible apoptosis and autophagy. The enhanced phototoxicity of encapsulated Pc was evident across multiple cancer cell lines, especially aggressive phenotypes, whereas resistant lines showed lower sensitivity likely due to efficient ROS scavenging. Despite improved initial uptake, rapid lysosomal release and extracellular extrusion of Pc limit long-term intracellular retention. Morphological and gene expression analyses confirmed distinct cell death mechanisms between free and encapsulated Pc, underscoring the critical role of nanocarrier-mediated delivery in modulating oxidative stress and cellular response. These findings highlight the importance of nanoparticle design in optimizing PDT efficacy by effectively triggering necrotic cell death pathway."

LRRK2 mutations increase the phosphorylation of Rab substrates including Rab12 and Rab10. Rab12 and Rab10 are expressed in neuronal and non-neuronal cells with localization to membranes in the endolysosomal compartment, and lysosomal stress activates LRRK2 phosphorylation of Rabs. In this study, using antibodies directed to the LRRK2-mediated phosphorylation sites on Rab12 at amino acid Ser106 (pS106-Rab12) and Rab10 at amino acid Thr73 (pT73-Rab10), we test whether aberrant LRRK2 phosphorylation is associated with tau and/or \u03b1-synuclein pathology across clinically distinct neurodegenerative diseases. Analysis of brain tissue lysates and immunohistochemistry of pathology-susceptible brain regions demonstrate that pS106-Rab12 levels are increased in Alzheimer's disease (AD) and Lewy body disease (LBD), including PD with and without G2019S LRRK2 mutation. At early pathological stages, phosphorylated Rab12 localizes to granulovacuolar degeneration bodies (GVBs), which are thought to be active lysosomal-like structures, in neurons. pS106-Rab12-positive GVBs accumulate with pathological tau across brain tissues in AD and LBD, and in G2019S LRRK2 mutation carriers. In a mouse model of tauopathy, pS106-Rab12 localizes to GVBs during early tau deposition in an age-dependent manner. While GVBs are largely absent in neurons with mature protein pathology, subsets of both tau and \u03b1-synuclein inclusions appear to incorporate pS106-Rab12 at later pathological stages. Further, pS106-Rab12 labels GVBs in neurons and shows co-pathology with tau inclusions in primary tauopathies including Pick's disease, progressive supranuclear palsy, and corticobasal degeneration. Finally, pT73-Rab10 is elevated and localizes to GVBs, but not tau and \u03b1-synuclein inclusions, in AD and LBD, including G2019S LRRK2 mutation carriers. These results implicate LRRK2 kinase activity and Rab phosphorylation in endolysosomal dysfunction in tau- and \u03b1-synuclein-associated neurodegenerative diseases."

Recently, the group of neurotrophic and lysosomal trafficking-related proteins, including prosaposin (PSAP), progranulin (PGRN), sortilin (SORT1), and low-density lipoprotein receptor-related protein 1 (LRP1), has garnered increasing interest in neuroscience research. The aim of this study was to profile the post-mortem levels of PSAP, PGRN, SORT1 and LRP1, and to determine whether these biomarkers could serve as diagnostic tools for mechanistic stratification in forensic neuropathology and medico-legal investigations. The study involved a total of 40 cases, individuals with head injuries (n\u202f=\u202f20) suspected to be the cause of death and control atraumatic cases of sudden death (n\u202f=\u202f20) due to cardiopulmonary reasons. Serum and cerebrospinal fluid (CSF), were collected approximately 24\u202fh post-mortem and analyzed through ELISA testing. Brain specimens were obtained during forensic autopsies and subjected to immunohistochemical staining. We observed the elevated concentration level of PSAP in CSF, and the elevated concentration level of PGRN within serum and CSF. In the frontal cortex, anti-SORT1 and anti-LRP1 immunostaining revealed a general homogenization of the reaction in the study group. The molecular and cellular evidence suggests lysosomal trafficking disruption as central element of fatal TBI. The redistribution of SORT1 and LRP1, together with CSF-specific PSAP elevation and systemic PGRN increase, support a model in which neuronal lysosomal stress, receptor trafficking breakdown, and systemic release of lysosomal proteins are intertwined. The potential use of PSAP, PGRN, SORT1, and LRP1 assays offers an novel tool for research regarding TBI diagnosis and pathogenesis."

Extracellular vesicles (EVs) have attracted growing interest as therapeutic vehicles owing to their inherent capacity to bypass the blood-brain barrier and deliver complex biological cargo to the central nervous system. Here, we examined whether large EVs (LEVs) derived from microglia with stable Sirtuin-2 knockdown (SIRT2-KD) confer the neuroprotective effects associated with SIRT2 inhibition. LEVs harvested from SIRT2-KD microglia were administered intranasally to APP/PS1 mice. We assessed microglial uptake of LEVs, along with subsequent changes in cellular metabolism, migration toward amyloid-beta (A\u03b2) plaques, phagocytic activity, and downstream pathological and behavioral outcomes. Proteomic and acetylomic profiling were employed to characterize the molecular cargo of LEVs-SIRT2-KD. LEVs-SIRT2-KD were readily internalized by microglia in vivo following intranasal delivery. Uptake of these vesicles markedly enhanced microglial bioenergetics, driving coordinated upregulation of both oxidative phosphorylation and glycolysis. This metabolic shift was accompanied by improved microglial recruitment to A\u03b2 plaques and increased phagocytic clearance. Consequently, treated mice showed reduced A\u03b2 plaque deposition, restored synaptic integrity, and reversal of cognitive deficits. Proteomic and acetylomic analyses revealed that LEVs-SIRT2-KD are selectively enriched in proteins and acetylation modifications linked to energy metabolism and phagocytic function, offering a mechanistic basis for the observed metabolic reprogramming. Together, these results identify LEVs as a critical vesicle subtype mediating the effects of SIRT2 knockdown and support a cell-free therapeutic strategy for AD centered on EVs-driven metabolic reprogramming of microglia."

Here, we investigated the biological effects of fucoidan (FU) and fucoidan nanoaggregates (NFU) in both thyroid cancer (SW1736) and non-tumorigenic thyroid cells (Nthy-ori 3.1). NFU showed a mean diameter of ~\u2009187\u00a0nm, a low polydispersity (~\u20090.2) and a negative Zeta potential. NFU significantly reduced SW1736 cell viability, reaching\u2009~\u200960% inhibition at 0.01\u00a0mg/mL and ~\u200980% at 0.1\u00a0mg/mL after 72\u00a0h, while sparing non-tumorigenic cells. Mechanistically, NFU induced marked lysosomal enlargement selectively in tumor cells and localized predominantly within LAMP-1-positive compartments. Consistently, tumor cells showed constitutive Cathepsin D maturation and enhanced sensitivity to NFU-induced lysosomal perturbation. Collectively, these findings identify lysosomes as a primary intracellular target of fucoidan-based nanosystems and reveal a tumor-selective vulnerability to NFU-mediated lysosomal stress. This study provides the first quantitative evidence of lysosomal targeting by fucoidan nanoparticles in thyroid cancer cells and supports NFU as a promising lysosome-directed nanotherapeutic strategy for aggressive thyroid malignancies."

Dysfunction in beta-glucocerebrosidase (GCase) and leucine-rich repeat kinase 2 (LRRK2) mutation are genetic risks for developing synucleinopathies. However, whether pharmacological GCase activation ameliorated synucleinopathies in LRRK2-PD was unexplored. Here, we showed that long-term treatment of ambroxol (ABX), a brain-penetrant GCase activator, reduced \u03b1-syn oligomer accumulation in aged mutant LRRK2R1441G mouse striatum. Acute ABX treatment (50\u2009\u00b5M) increased cellular GCase enzymatic activity and reduced Ser129-\u03b1-syn phosphorylation in human SH-SY5Y cells and mutant LRRK2 mouse fibroblasts, independent to LRRK2 kinase activity. Real-time DQ-BSA assay revealed lysosomal dysfunction in mutant MEFs, which was partially attenuated by ABX treatment. Lysosomal stress by bafilomycin-A1 induced endogenous GCase activity in wildtype (WT) MEFs, which was not observed in the LRRK2 mutant. Single gavage of ABX (400\u2009mg/kg) in aged mice achieved peak drug level in serum and brain within 6\u2009h post-administration. Ad libitum feeding of ABX (in food pellets) over 18 weeks (average dose: 45.9\u2009mg/kg/day) elevated brain GCase activity in both WT and mutant striatum without affecting body weight. This regimen significantly reduced \u03b1-syn oligomer level in mutant striatum to a comparable physiological level in age-matched WT without altering total \u03b1-syn and Ser129-phosphorylation levels. This is the first study demonstrating reduced \u03b1-syn oligomer accumulation by chronic treatment of GCase activator in aged mouse brains vulnerable to PD, suggesting early intervention to alter progression of synucleinopathies as a key determinant of clinical outcomes of PD."

Although environmentally aged MNPs predominate, their developmental toxicity remains poorly understood. We demonstrate that both pristine and aged polystyrene nanoplastics (PSNPs) induce abnormal lipid accumulation and impair early development in zebrafish larvae. Lipidomics revealed aged PSNPs significantly increased triglycerides via disrupted glycerophospholipid metabolism. Mechanistically, aged PSNPs did not alter LC3-II/LC3-I ratios but upregulated RAB7 and p62 while downregulating lysosomal biogenesis regulator TFEB. They also reduced ATG5, essential for autophagosome formation via LC3 lipidation. These molecular alterations, together with lysosomal inhibition assays, functionally support lysosomal dysfunction as a key constraint on lipophagy. This impairment inhibits lipid utilization, promotes accumulation, and disrupts development. Critically, aged PSNPs caused stronger disruption than pristine particles despite both interfering with lipophagy. Our study provides mechanistic insights into the developmental toxicity of UV-aged PSNPs in zebrafish, highlighting the importance of considering aging-related changes in nanoplastic risk evaluation. SYNOPSIS: Aged nanoplastics exacerbate developmental toxicity in zebrafish by suppressing lipophagy to drive lipid accumulation, underscoring ecological risks in aquatic systems."

It is characterized by the progressive loss of dopaminergic neurons in the substantia nigra and the accumulation of misfolded \u03b1-synuclein (\u03b1Syn) in intracellular inclusions known as Lewy bodies. Emerging evidence links \u03b1Syn accumulation to impaired lysosomal acidification and defective autophagy-lysosomal degradation, which are central to disease progression. To address this lysosomal dysfunction, we engineered a novel type of lysosome-targeted acidic nanoparticles (AcNPs) based on a biodegradable copolymer, poly(ethylene tetrafluorosuccinate-co-succinate) (PEFSU). These nanomaterials were developed to locally acidify impaired lysosomes and restore their degradative capacity. We evaluated their therapeutic potential in two familial PD models: SH-SY5Y neuroblastoma cells overexpressing A30P \u03b1Syn and A30P \u03b1Syn transgenic Drosophila melanogaster. In vitro, AcNPs effectively restored lysosomal pH, enhanced autophagic clearance of \u03b1Syn, improved mitochondrial function, and rescued A30P \u03b1Syn-induced cytotoxicity. In vivo, AcNPs treatment reduced \u03b1Syn burden, preserved dopaminergic neurons, and improved motor function in flies. This study demonstrates the first application of lysosome-acidifying polymeric nanoparticles in familial PD models and highlights the promise of rationally engineered pH-modulating nanomaterials as therapeutic agents for PD and other neurodegenerative diseases driven by lysosomal dysfunction and protein aggregation."

"abstract_text": "ID: 41533007\nTitle: PLGA nanoparticles restore acidic pH and degradative function to compromised lysosomes with Cy3-labeling providing enhanced tracking to lysosomes.\nAbstract: Lysosomal dysfunction and elevated lysosomal pH are hallmark features of age-related neurodegenerative diseases including age-related macular degeneration (AMD), Alzheimer's disease (AD), and Parkinson's disease (PD). Restoring lysosomal acidity is important for maintaining enzymatic degradation, preventing protein aggregation, and reducing cellular waste accumulation in degenerating tissues. Acidic nanoparticles represent a promising therapeutic strategy to normalize lysosomal pH; however, accurate monitoring of their delivery, retention, and dosage is critical for rigorous evaluation. To address this, we developed fluorescently labeled poly(d,l-lactide-co-glycolide) (PLGA) nanoparticles conjugated with Cyanine3 amine (Cy3). Nanoparticle uptake was systematically optimized, achieving over 90% delivery to lysosomes of induced pluripotent stem cell-derived retinal pigment epithelial (iPS-RPE) cells, although uptake rates varied among adjacent cells. Once internalized, nanoparticles demonstrated remarkable stability, with no detectable change in concentration, distribution, or size for at least 28 days. iPS-RPE cells exhibited higher nanoparticle internalization compared with the ARPE-19 cell line and optic nerve head astrocytes. The capacity of the nanoparticles to restore function to stressed lysosomes was confirmed by their ability to reacidify lysosomes, restore cathepsin B activity, and increase the levels of active cathepsin D. The nanoparticles also reduced the levels of LC3II in astrocytes treated with chloroquine, indicating that they can also restore autophagy rates. In summary, this study demonstrates the value of Cy3 labeling for enhanced nanoparticle tracking to lysosomes. The findings also identify PLGA nanoparticles as powerful tools for restoring degradative lysosomal function and autophagy in cells undergoing lysosomal stress.NEW & NOTEWORTHY Tools that restore acidic pH in compromised lysosomes can enhance autophagy and waste clearance in degenerative disorders characterized by excessive accumulation. Here, we describe the synthesis of lysosome-targeted nanoparticles composed of poly(d,l-lactide-co-glycolide) (PLGA) polymers covalently bound to the fluorescent dye Cyanine3 amine (Cy3). These Cy3-PLGA nanoparticles enable precise tracking of lysosomal delivery and demonstrate sustained long-term retention within lysosomes, supporting their potential for future applications aimed at restoring lysosomal pH in aging and degenerating diseases."

Astrocytes also regulate neuronal functions and survival by modulating myelination and degradation of pathological toxic protein aggregates. Astrocytes have recently been proposed to possess both autophagic activity and active phagocytic capability which largely depend on sufficiently acidified lysosomes for complete degradation of cellular cargos. Defective lysosomal acidification in astrocytes impairs their autophagic and phagocytic functions, resulting in the accumulation of cellular debris, excessive myelin and lipids, and toxic protein aggregates, which ultimately contributes to the propagation of neuroinflammation and neurodegenerative pathology. Restoration of lysosomal acidification in impaired astrocytes represent new neuroprotective strategy and therapeutic direction. In this review, we summarize pathogenic factors, including neuroinflammatory signaling, metabolic stressors, myelin and lipid mediated toxicity, and toxic protein aggregates, that contribute to lysosomal acidification impairment and associated autophagic and phagocytic dysfunction in astrocytes. We discuss the role of lysosomal acidification dysfunction in astrocyte-mediated neuroinflammation primarily in the context of neurodegenerative diseases along with other brain injuries. We then highlight re-acidification of impaired lysosomes as a therapeutic strategy to restore autophagic and phagocytic functions as well as lysosomal degradative capacity in astrocytes. We conclude by providing future perspectives on the role of astrocytes as phagocytes and their crosstalk with other CNS cells to impart neurodegenerative or neuroprotective effects."

Lysosomal function, autophagy, pathological protein clearance, and anti-inflammatory effects were assessed using various cellular and molecular biology techniques. MSC-PLGA-NPs demonstrated 2.3-fold higher BBB penetration efficiency compared to PLGA alone. In a chloroquine(CQ)-induced lysosomal injury model and mice model, they effectively restored lysosomal pH, enhanced autophagy (reducing LC3-II/I ratio by 0.4-fold and p62 expression by 52%), cleared amyloid precursor protein (APP) and phosphorylated tau (p-tau) proteins, and inhibited IL-6 and TNF-\u03b1 without hepatorenal toxicity.

Conjugation of ATG8s to single membranes (CASM) is a noncanonical LC3\u2011lipidation pathway activated by various stressors, distinct from canonical autophagy. We previously showed that TBT reduces lysosomal acidity and inhibits autophagy in SH-SY5Y cells. Furthermore, we observed TBT-induced LC3-II accumulation, which was reduced by bafilomycin A1, and tubular LC3-positive structures as hallmarks of CASM. In this study, we investigated whether TBT activates CASM. TBT (700\u00a0nM) induced LC3-II accumulation, which was completely blocked by bafilomycin A1 in SH-SY5Y and HeLa cells. Unlike autophagy, TBT induced LC3-II accumulation even under class III PI3K inhibition by wortmannin and in FIP200-knockout cells. Salmonella effector protein SopF, which inhibits V-ATPase-ATG16L1 association required for CASM, inhibited TBT-induced LC3-II accumulation.

In this study, NP was synthesized successfully with an average particle size of 100\u00a0nm using a emulsion polymerization method as model particles. Following co-incubation of IEC-6 cells with NP for 24-168\u00a0h, a notable inhibition of cell viability and proliferation was observed. The significant activation of autophagy and a concomitant blockage of autophagic flux in IEC-6 cells after 24-72\u00a0h of co-incubation with NP were unveiled by transmission electron microscopy, western blotting, and double-fluorescent autophagy analysis. A significant increase in the number of lysosomes and an increase in the expression of hydrolase CTSB were detected, indicating dysregulation of lysosomal function. The subsequent transcriptomic and metabolomics analyses, coupled with the observation of activated lysosomes and the RIPK1-RIPK3-MLKL/PYGL pathway, led us to posit that the blockade of autophagy and lysosomal dysfunction, culminating in lysosomal membrane permeabilization (LMP) induced necroptosis, constitutes one of the mechanisms contributing to the cytotoxicity of NP.

However, antibiotic resistance has become a compelling health issue, leading to H. pylori eradication treatment failure worldwide. Additionally, the powerlessness of antibiotics against biofilms, as well as intracellular H. pylori and the long-term damage of antibiotics to the intestinal microbiota, have also created an urgent demand for antibiotic-free approaches.

Here we present a versatile DNA nanostructure-based platform that can modulate a number of cellular functions depending on the concentration and surface decoration of the nanostructure. Utilizing different peptides for surface functionalization of DNs, we were able to rationally modulate lysosomal activity, which in turn translated into the control of cellular function, ranging from changes in cell morphology to modulation of immune signaling and cell death. Low concentrations of decalysine peptide-coated DNs induced lysosomal acidification, altering the metabolic activity of susceptible cells. In contrast, DNs coated with an aurein-bearing peptide promoted lysosomal alkalization, triggering STING activation. High concentrations of decalysine peptide-coated DNs caused lysosomal swelling, loss of cell-cell contacts, and morphological changes without inducing cell death. Conversely, high concentrations of aurein-coated DNs led to lysosomal rupture and mitochondrial damage, resulting in significant cytotoxicity. Our study holds promise for the rational design of a new generation of versatile DNA-based nanoplatforms that can be used in various biomedical applications, like the development of combinatorial anti-cancer platforms, efficient systems for endolysosomal escape, and nanoplatforms modulating lysosomal pH."

To disrupt this metabolic adaptability, we herein engineer a homotypic membrane-camouflaged nanomedicine capable of hypoxia-responsive cascade drug release and enhanced tumor accumulation. The resulting nanomedicine performs a hypoxia-induced phase transition that first liberates glucose oxidase to intensify oxygen deprivation and subsequently triggers burst release of chloroquine. Such a design of self-amplified relay drug release ensures effective starvation induction and precise lysosomal alkalization, thereby shutting down lysosome-mediated nutrient recycling. In a xenograft orthotopic PDAC model, this nanomedicine achieves 9.75-fold increase in tumor accumulation, robust tumor inhibition of 92.8%, and an elevated survival rate of 80% with favorable biosafety. Collectively, our findings highlight lysosomal disruption as a therapeutic lever to potentiate starvation therapy and provide a clinically actionable nanoplatform to enhance metabolic interventions for other metabolically vulnerable malignancies."

However, this requires the use of excessive light energy to obtain good signal-to-noise ratio, which can then photobleach fluorochromes, and more worrisomely, lead to phototoxicity. Upon light excitation, noble metal nanoparticles such as silver nanoparticles (AgNPs) generate plasmons, which can then amplify excitation in direct proximity of the nanoparticle's surface and couple to the oscillating dipole of nearby radiating fluorophores, modifying their rate of emission and thus, enhancing their fluorescence. Here, we show that AgNPs fed to cells to accumulate within lysosomes enhanced the fluorescence of lysosome-targeted Alexa488-conjugated dextran, BODIPY-cholesterol, and DQ-BSA. Moreover, AgNP increased the fluorescence of GFP fused to the cytosolic tail of LAMP1, showing that metal enhanced fluorescence can occur across the lysosomal membrane. The inclusion of AgNPs in lysosomes did not disturb lysosomal properties such as lysosomal pH, degradative capacity, autophagy and autophagic flux, and membrane integrity, though AgNP seemed to increase basal lysosome tubulation. Importantly, by using AgNP, we could track lysosome motility with reduced laser power without damaging and altering lysosome dynamics. Overall, AgNP-enhanced fluorescence may be a useful tool to study the dynamics of the endo-lysosomal pathway while minimizing phototoxicity."

This leads to marked lysosomal stress and regulated necrotic cell death pathway, while free Pc causes moderate oxidative stress with reversible apoptosis and autophagy. The enhanced phototoxicity of encapsulated Pc was evident across multiple cancer cell lines, especially aggressive phenotypes, whereas resistant lines showed lower sensitivity likely due to efficient ROS scavenging.

LRRK2 mutations increase the phosphorylation of Rab substrates including Rab12 and Rab10. Rab12 and Rab10 are expressed in neuronal and non-neuronal cells with localization to membranes in the endolysosomal compartment, and lysosomal stress activates LRRK2 phosphorylation of Rabs. In this study, using antibodies directed to the LRRK2-mediated phosphorylation sites on Rab12 at amino acid Ser106 (pS106-Rab12) and Rab10 at amino acid Thr73 (pT73-Rab10), we test whether aberrant LRRK2 phosphorylation is associated with tau and/or \u03b1-synuclein pathology across clinically distinct neurodegenerative diseases. Analysis of brain tissue lysates and immunohistochemistry of pathology-susceptible brain regions demonstrate that pS106-Rab12 levels are increased in Alzheimer's disease (AD) and Lewy body disease (LBD), including PD with and without G2019S LRRK2 mutation. At early pathological stages, phosphorylated Rab12 localizes to granulovacuolar degeneration bodies (GVBs), which are thought to be active lysosomal-like structures, in neurons. pS106-Rab12-positive GVBs accumulate with pathological tau across brain tissues in AD and LBD, and in G2019S LRRK2 mutation carriers. In a mouse model of tauopathy, pS106-Rab12 localizes to GVBs during early tau deposition in an age-dependent manner. While GVBs are largely absent in neurons with mature protein pathology, subsets of both tau and \u03b1-synuclein inclusions appear to incorporate pS106-Rab12 at later pathological stages. Further, pS106-Rab12 labels GVBs in neurons and shows co-pathology with tau inclusions in primary tauopathies including Pick's disease, progressive supranuclear palsy, and corticobasal degeneration. Finally, pT73-Rab10 is elevated and localizes to GVBs, but not tau and \u03b1-synuclein inclusions, in AD and LBD, including G2019S LRRK2 mutation carriers. These results implicate LRRK2 kinase activity and Rab phosphorylation in endolysosomal dysfunction in tau- and \u03b1-synuclein-associated neurodegenerative diseases."

Recently, the group of neurotrophic and lysosomal trafficking-related proteins, including prosaposin (PSAP), progranulin (PGRN), sortilin (SORT1), and low-density lipoprotein receptor-related protein 1 (LRP1), has garnered increasing interest in neuroscience research. The aim of this study was to profile the post-mortem levels of PSAP, PGRN, SORT1 and LRP1, and to determine whether these biomarkers could serve as diagnostic tools for mechanistic stratification in forensic neuropathology and medico-legal investigations. The study involved a total of 40 cases, individuals with head injuries (n\u202f=\u202f20) suspected to be the cause of death and control atraumatic cases of sudden death (n\u202f=\u202f20) due to cardiopulmonary reasons. Serum and cerebrospinal fluid (CSF), were collected approximately 24\u202fh post-mortem and analyzed through ELISA testing. Brain specimens were obtained during forensic autopsies and subjected to immunohistochemical staining. We observed the elevated concentration level of PSAP in CSF, and the elevated concentration level of PGRN within serum and CSF. In the frontal cortex, anti-SORT1 and anti-LRP1 immunostaining revealed a general homogenization of the reaction in the study group. The molecular and cellular evidence suggests lysosomal trafficking disruption as central element of fatal TBI. The redistribution of SORT1 and LRP1, together with CSF-specific PSAP elevation and systemic PGRN increase, support a model in which neuronal lysosomal stress, receptor trafficking breakdown, and systemic release of lysosomal proteins are intertwined. The potential use of PSAP, PGRN, SORT1, and LRP1 assays offers an novel tool for research regarding TBI diagnosis and pathogenesis."

Extracellular vesicles (EVs) have attracted growing interest as therapeutic vehicles owing to their inherent capacity to bypass the blood-brain barrier and deliver complex biological cargo to the central nervous system. Here, we examined whether large EVs (LEVs) derived from microglia with stable Sirtuin-2 knockdown (SIRT2-KD) confer the neuroprotective effects associated with SIRT2 inhibition. LEVs harvested from SIRT2-KD microglia were administered intranasally to APP/PS1 mice. We assessed microglial uptake of LEVs, along with subsequent changes in cellular metabolism, migration toward amyloid-beta (A\u03b2) plaques, phagocytic activity, and downstream pathological and behavioral outcomes. Proteomic and acetylomic profiling were employed to characterize the molecular cargo of LEVs-SIRT2-KD. LEVs-SIRT2-KD were readily internalized by microglia in vivo following intranasal delivery. Uptake of these vesicles markedly enhanced microglial bioenergetics, driving coordinated upregulation of both oxidative phosphorylation and glycolysis. This metabolic shift was accompanied by improved microglial recruitment to A\u03b2 plaques and increased phagocytic clearance. Consequently, treated mice showed reduced A\u03b2 plaque deposition, restored synaptic integrity, and reversal of cognitive deficits. Proteomic and acetylomic analyses revealed that LEVs-SIRT2-KD are selectively enriched in proteins and acetylation modifications linked to energy metabolism and phagocytic function, offering a mechanistic basis for the observed metabolic reprogramming. Together, these results identify LEVs as a critical vesicle subtype mediating the effects of SIRT2 knockdown and support a cell-free therapeutic strategy for AD centered on EVs-driven metabolic reprogramming of microglia."

Dysfunction in beta-glucocerebrosidase (GCase) and leucine-rich repeat kinase 2 (LRRK2) mutation are genetic risks for developing synucleinopathies. However, whether pharmacological GCase activation ameliorated synucleinopathies in LRRK2-PD was unexplored. Here, we showed that long-term treatment of ambroxol (ABX), a brain-penetrant GCase activator, reduced \u03b1-syn oligomer accumulation in aged mutant LRRK2R1441G mouse striatum. Acute ABX treatment (50\u2009\u00b5M) increased cellular GCase enzymatic activity and reduced Ser129-\u03b1-syn phosphorylation in human SH-SY5Y cells and mutant LRRK2 mouse fibroblasts, independent to LRRK2 kinase activity. Real-time DQ-BSA assay revealed lysosomal dysfunction in mutant MEFs, which was partially attenuated by ABX treatment. Lysosomal stress by bafilomycin-A1 induced endogenous GCase activity in wildtype (WT) MEFs, which was not observed in the LRRK2 mutant. Single gavage of ABX (400\u2009mg/kg) in aged mice achieved peak drug level in serum and brain within 6\u2009h post-administration. Ad libitum feeding of ABX (in food pellets) over 18 weeks (average dose: 45.9\u2009mg/kg/day) elevated brain GCase activity in both WT and mutant striatum without affecting body weight. This regimen significantly reduced \u03b1-syn oligomer level in mutant striatum to a comparable physiological level in age-matched WT without altering total \u03b1-syn and Ser129-phosphorylation levels. This is the first study demonstrating reduced \u03b1-syn oligomer accumulation by chronic treatment of GCase activator in aged mouse brains vulnerable to PD, suggesting early intervention to alter progression of synucleinopathies as a key determinant of clinical outcomes of PD."

Mycolactone inhibits the Sec61-dependent co-translational translocation of signal peptide-bearing secreted and membrane proteins into the endoplasmic reticulum. Sec61 inhibition leads to accumulation of mislocalised proteins in the cytosol and initially triggers an integrated stress response-dependent activation of autophagy that contributes to cell survival. Here we show sustained exposure to mycolactone blocks late-stage autophagy and induces nuclear translocation of the lysosomal stress marker TFEB. This follows loss of ATP6AP1 and ATP6AP2, Sec61-substrates required for assembly of the Vacuolar-ATPase, leading to reduced lysosomal biogenesis and acidification. These effects are reduced in cells expressing a mycolactone-resistant Sec61\u03b1 mutant and phenocopied by other Sec61 inhibitors. Loss of lysosomal function compromises the cell's capacity to withstand the proteostatic stress caused by Sec61 inhibition and could impair the ability of phagocytes to combat infection with M. ulcerans and contribute to the tissue necrosis in Buruli ulcer. Furthermore, since Sec61 inhibition is being pursued as a therapeutic target in several diseases, potential drugs should be screened against this activity to avoid unwanted side-effects."

The HIV-1 envelope glycoprotein gp120 causes LSR, increases levels of ferrous iron (Fe2+) in the cytosol and in mitochondria, disrupts the reactive species interactome (RSI), and increases neural cell death. Using SH-SY5Y human neuroblastoma and U87MG human astrocytoma cells treated with gp120 and pharmacological modulators, we evaluated redox signaling and LSR by redox-sensitive fluorescent probes, spinning-disk confocal microscopy, flow cytometry, Western blotting, and immunostaining. Here, we report that TRPML1, an endolysosome redox-sensitive cation channel, is mechanistically involved in gp120-induced neurotoxicity. TRPML1 was activated by gp120-induced increases in cytosolic reactive oxygen species (ROS) and resulted in release of Fe2+ from endolysosomes in levels sufficient to increase cytosolic levels of Fe2+ and ROS as well as decrease levels of hydrogen sulfide (H2S). Reduced glutathione normally buffers intracellular Fe2+, but gp120 decreased endolysosome glutathione levels and disrupted this regulatory control mechanism thereby promoting TRPML1-mediated Fe2+ efflux from endolysosomes. TRPML1 redox activation led to changes to the RSI in endolysosomes including increased ROS, lipid peroxidation, nitric oxide, and sulfane sulfur as well as decreased H2S. These changes were accompanied by increased cysteine oxidation of luminal proteins and endolysosome deacidification. Pharmacological inhibition of TRPML1 or knocking down expression levels of TRPML prevented these effects. Our findings suggest that TRPML1 redox activation controls gp120-induced endolysosome dysfunction and iron/redox imbalance, and further implicates TRPML1 in the pathogenesis of HAND."

Tetracyclines, particularly doxycycline, have demonstrated multimodal neuroprotective effects, both in vitro and in vivo. The non-antibiotic derivative of doxycycline 4-dedimethylamino-12a-deoxydoxycycline (DDOX), has been recently shown to rescue neurons from oxidative injury. Here, we demonstrate that DDOX showcases a diverse range of mechanisms targeting \u03b1-Syn aggregates. Notably, DDOX inhibited the aggregation of \u03b1-Syn and the seeding ability of \u03b1-Syn pre-formed fibrils (PFF) in biophysical and cellular assays. In addition, the compound ameliorated the relocalization of total and phospho-\u03b1-Syn, triggered by exogenous \u03b1-Syn PFF. Surprisingly, DDOX drastically mitigated lysosomal stress induced by these aggregates. Moreover, we determined that DDOX effectively impeded the internalization of fluorescently labeled \u03b1-Syn PFF. Biophysical techniques and molecular docking simulations suggest that DDOX binds to hydrophobic patches on \u03b1-Syn fibrils. Our findings reveal novel neuroprotective attributes of tetracyclines, wherein a direct extracellular interaction between DDOX and \u03b1-Syn aggregated species mitigates their intracellular impact. These results provide a promising foundation for DDOX, a drug that aims to interfere with the intracellular seeding, propagation and uptake of \u03b1-Syn fibrils in neurodegenerative conditions."

Restoring lysosomal acidity is important for maintaining enzymatic degradation, preventing protein aggregation, and reducing cellular waste accumulation in degenerating tissues. Acidic nanoparticles represent a promising therapeutic strategy to normalize lysosomal pH; however, accurate monitoring of their delivery, retention, and dosage is critical for rigorous evaluation. To address this, we developed fluorescently labeled poly(d,l-lactide-co-glycolide) (PLGA) nanoparticles conjugated with Cyanine3 amine (Cy3). Nanoparticle uptake was systematically optimized, achieving over 90% delivery to lysosomes of induced pluripotent stem cell-derived retinal pigment epithelial (iPS-RPE) cells, although uptake rates varied among adjacent cells. Once internalized, nanoparticles demonstrated remarkable stability, with no detectable change in concentration, distribution, or size for at least 28 days. iPS-RPE cells exhibited higher nanoparticle internalization compared with the ARPE-19 cell line and optic nerve head astrocytes. The capacity of the nanoparticles to restore function to stressed lysosomes was confirmed by their ability to reacidify lysosomes, restore cathepsin B activity, and increase the levels of active cathepsin D. The nanoparticles also reduced the levels of LC3II in astrocytes treated with chloroquine, indicating that they can also restore autophagy rates. In summary, this study demonstrates the value of Cy3 labeling for enhanced nanoparticle tracking to lysosomes. The findings also identify PLGA nanoparticles as powerful tools for restoring degradative lysosomal function and autophagy in cells undergoing lysosomal stress.NEW & NOTEWORTHY Tools that restore acidic pH in compromised lysosomes can enhance autophagy and waste clearance in degenerative disorders characterized by excessive accumulation. Here, we describe the synthesis of lysosome-targeted nanoparticles composed of poly(d,l-lactide-co-glycolide) (PLGA) polymers covalently bound to the fluorescent dye Cyanine3 amine (Cy3). These Cy3-PLGA nanoparticles enable precise tracking of lysosomal delivery and demonstrate sustained long-term retention within lysosomes, supporting their potential for future applications aimed at restoring lysosomal pH in aging and degenerating diseases."

Inherent differences in these culture/exposure modalities, such as particle behavior and deposited dose, likely affect cellular responses. To investigate this, we exposed submerged human bronchial epithelial cells (BEAS-2B) to polystyrene (PS) MNPs vs. aerosol exposure of ALI cultures. First, submerged bronchial epithelial cells (BEAS-2B) were exposed to suspensions of PS particles (50\u2009nm or 1\u2009\u00b5m) in four different applied concentrations (0.79-50\u2009\u00b5g/cm2; 24\u2009h). Second, BEAS-2B cells were cultured at ALI and exposed in a cloud system to PS 1\u2009\u00b5m particles (deposited dose: 55.4\u2009\u00b5g/cm2; 24\u2009h). Toxicity readouts focused on cytotoxicity (LDH release), inflammation (IL-8 release and transcriptional activation of inflammatory genes), and oxidative stress (DCFH-DA assay, antioxidant gene expression, and assessment of reduced/oxidized glutathione). In both models, PS exposure did not induce cell death, or an antioxidant response. However, NF-\u03baB transcriptional activity was strongly upregulated in submerged cells in response to both sizes of PS particles in a dose-dependent manner. Gene expression of CXCL1, CXCL2, and CXCL8 increased up to 7-fold after PS microplastic exposure (50\u2009\u00b5g/cm2) in the submerged model (which was less pronounced in response to PS nanoplastics) and 2-fold in the ALI model. In contrast, IL-8 secretion increased 1.6-fold for the ALI, but not the submerged model. Overall, both exposure modalities revealed an inflammatory response toward PS MNPs although with differences, likely due to significant differences in deposited dose. Very small plastic particles, called microplastics and nanoplastics (MNPs), are present in the air and can be inhaled into the lungs. To study possible health effects, scientists often expose lung cells to these particles in liquid (submerged) culture systems. However, this does not closely match how people are exposed through breathing. This study used a traditional liquid-based method and a more realistic system that exposes lung cells to plastic particles through the air. More specifically, human lung cells were exposed to polystyrene (PS) plastic particles of different sizes using either liquid exposure or an air\u2013liquid interface system, where particles were delivered as an aerosol, similar to inhalation. The researchers looked for signs of cell damage, inflammation, and oxidative stress. The results showed that the plastic particles did not kill the cells and did not cause oxidative stress in either exposure method. However, both methods caused signs of inflammation, which is a normal response of the body to foreign substances. In the liquid-based system, inflammation-related genes were strongly activated. In the air-exposed system, gene activation was weaker, but cells released higher levels of an inflammatory signaling protein. Importantly, the air-based exposure better reflects how people actually breathe in particles and avoids some problems linked to liquid-based testing. This study shows that there are differences in cellular responses to MNPs depending on the dose, particle behavior and culture system, which are all connected to each other."

However, whether NPs induce renal fibrosis remains contentious, and the reversibility of NPs-triggered nephrotoxicity has rarely been reported. This study investigated the role of lysosomes in renal fibrosis induced by low-level polystyrene (PS) NPs with particle sizes of 100 and 500 nm (PS100 and PS500) in mice using Masson staining, immunohistochemistry, Western blotting, fluorescence imaging, and other techniques. The results showed that PS100 induced more pronounced renal fibrosis than PS500. Mechanistically, PS NPs promoted autophagosome formation accompanied by the inhibition of autophagic degradation. Moreover, PS NPs impaired lysosomal degradation function, evidenced by reduced CTSB and CTSD protein levels. This impairment blocked autophagic flux, thereby inducing renal fibrosis, which was further confirmed by in vitro results. Notably, lysosomal exocytosis plays a crucial role in the clearance of NPs from mouse kidneys through activating Mcoln1 expression, which contributes to restoring autophagic flux and alleviating renal fibrosis during recovery. Collectively, our findings provide the first evidence that lysosomes serve dual functions in the persistence and reversibility of NPs-induced nephrotoxicity, which could be valuable for the intervention and mitigation of kidney damage resulting from environmental NPs exposure."

However, most siRNA can't exert a therapeutic effect due to a lack of targeting to tumor cells and entrapment in lysosomes upon administration. To address the challenges associated with siRNA delivery, a delivery system was developed using zinc oxide nanoparticles (ZnO NPs) coated with cancer cell membranes. ZnO nanoparticles (ZnO NPs) have been recognized as effective pH-responsive nanoparticles and are widely used in the development of pH-responsive drug delivery systems. The ZnO NPs were combined with chitosan to encapsulate siRNA, allowing for dissolution in acidic lysosomes and the subsequent release of siRNA and chitosan complexes. The dissolution of ZnO NPs would also disrupt lysosomes, facilitating the escape of siRNA and enhancing its gene silencing effect. However, the chitosan and ZnO NPs nano-complexes (CS/ZnO@siRNA) were unstable in solution and lacked a specific targeting effect for tumor cells. Thus, a homologous cancer cell membrane was coated onto the nanoparticles, which has been shown to be an effective strategy for enhancing their stability and targeting capabilities. Moreover, ZnO NPs not only dissolve in acidic lysosomes to enhance the efficacy of siRNA but also elevate oxidative stress levels in cells, leading to the induction of cellular apoptosis. It was demonstrated both in vitro and in vivo that the ZnO NPs could synergistically combine with the anti-tumor siRNA (siSurvivin) to inhibit the growth of the 4T1 tumor. Altogether, the developed drug delivery system (CCM-CS/ZnO@siSurvivin) offers a new strategy for enhancing the therapeutic effect of siRNA, while synergistically inhibiting tumor growth.

However, the underlying mechanism for the toxic effects of nanoplastics on the BBB remain poorly understood. In this study, we explored the toxic effects of polystyrene nanoplastic (PSNP) on brain microvascular endothelial cells (BMECs), one of the most critical components for maintaining BBB integrity. Our results revealed that PSNP specifically accumulate in the endolysosomal system following their internalization by BMECs. This accumulation disrupts lysosomal function and blocks endolysosomal pathways, ultimately triggering methuosis-a unique form of cell death characterized by extensive cytoplasmic vacuolization. Although the endosomal sorting complexes required for transport (ESCRT) system is naturally activated as a cellular defense mechanism, it is insufficient to repair PSNP-induced lysosomal membrane damage. By enhancing ESCRT activity, we effectively restored lysosomal function, thereby preventing cellular methuosis and preserving BBB integrity. Therefore, our findings provide crucial insights into the mechanisms underlying PSNP-induced BBB disruption by focusing on methuosis in endothelial cells. These insights hold important implications for environmental toxicology and public health in the context of global plastic pollution."

However, most existing research has focused on single exposure, which is not consistent with the actual exposure circumstance. In this study, single and co-exposure animal model were established. C57/BL6J mice were exposed to corn oil, 20\u00a0mg/kg PS-MPs, 200\u00a0mg/kg DEHP and PS-MPs\u00a0+\u00a0DEHP for 28 days. The HE staining showed more serious seminiferous epithelium disorganization in co-exposed mice, indicating that PS-MPs and DEHP co-exposure could aggravate testicular injury. Compared with control group, integrative analysis of transcriptomics and proteomics revealed that PPAR\u03b3 pathway played a crucial role in PS-MPs and DEHP co-exposure induced testis injury. In vitro, spermatocytes (GC-2) and leydig cells (TM3) were exposed to 50\u00a0\u03bcM MEHP, 10\u00a0mg/L PS-MPs and PS-MPs\u00a0+\u00a0MEHP for 48\u00a0h. Though PS-MPs and MEHP single exposure also triggered oxidative stress and PPAR pathway, the protein levels showed more remarkable difference in co-exposure group. Furthermore, co-exposure to PS-MPs and MEHP induced lysosomal membrane permeabilization (LMP), which significantly impaired lysosomal-mediated lipid degradation, thereby exacerbating lipid metabolism dysfunction in testicular cells. Treatment with N-Acetylcysteine (NAC) and knockdown of fatty acid-binding protein (FABP4) restored lipophagy flux and reduced lipid droplets deposition. Overall, co-exposure of PS-MPs and DEHP has synergistic toxic effect, inducing oxidative stress, PPAR\u03b3 activation and lipophagy blockage, finally resulting in unbalanced lipid metabolism and testicular damage."

Environmental toxins are considered the main etiological factor. The increasing use of polystyrene nanoparticles (PS-NPs) has raised concerns about their potential neurotoxic effects in PD. This study aimed to investigate the impact of PS-NPs on the onset and progression of PD and the underlying mechanisms. The breach of the blood-brain barrier (BBB) by PS-NPs was assessed using bioluminescence imaging, fluorescence observation, Pyrolysis-Gas Chromatography-Mass Spectrometry (Py-GCMs), transmission electron microscope (TEM), and Evans blue staining. To evaluate the potential promotion of PD by PS-NPs, a 30-day repeated oral administration study was conducted in vivo, during which behavioral changes and alterations in dopaminergic neurons in the substantia nigra were assessed. In vitro cytotoxicity assays were performed following PS-NPs intervention. Molecular biology techniques, including Western blotting and immunofluorescence, were employed to analyze proteins related to pyroptosis and autophagy-lysosomal pathway in both in vivo and in vitro settings. Additionally, proteomic sequencing was utilized to identify the upstream regulator of the autophagy-lysosomal pathway (ALP), and the effects of modulating this target protein on the ALP-pyroptosis pathway were analyzed. Bioluminescence imaging and Py-GCMs confirmed that PS-NPs entered the brain within 1.5\u00a0h. Evans blue staining and TEM showed PS-NPs damaged the BBB. The 30-day oral toxicity revealed that PS-NPs exacerbated behavioral abnormalities and caused dopaminergic neuron loss. Western blotting and immunofluorescence indicated that PS-NPs induced pyroptosis, disrupted autophagic flux, and lowered protein levels involved in autophagosome-lysosome fusion, both in vivo and in vitro. Furthermore, PS-NPs activated the mechanistic target of rapamycin (mTOR) and inhibited the nuclear translocation of Transcription Factor EB (TFEB). Proteomic sequencing identified a deficit of Tuberous Sclerosis Complex (TSC) 2 protein within the mTOR pathway. Immuno-coprecipitation and Coomassie Blue Fast Staining revealed that PS-NPs bound to TSC2 protein, causing disassembly of TSC1-TSC2 complex. These findings underscore how PS-NPs accelerated PD onset and progression by disrupting autophagosome-lysosome fusion through TSC2-mTOR-TFEB axis, which triggered protein degradation disorders and pyroptosis in dopaminergic neurons. The molecular mechanisms could inform environmental safety regulations concerning nanoplastics and inspire therapeutic strategies for PD."

However, how food components influence MNP release from packaging materials and the resulting exposure risks remain poorly understood. Here, we investigated the effect of the primary tea polyphenol, epigallocatechin gallate (EGCG), on MNP release from polystyrene cups during a simulated tea-drinking process involving thermal treatments. A surface-enhanced Raman scattering sensor was developed to quantify released plastic particles in situ using EGCG-based luminescent metal-phenolic network labeling. The released particles were identified primarily as nanoplastics, and the presence of EGCG significantly (P < 0.05) increased MNP release, particularly during microwave heating and most prominently upon repeated cup use. Interestingly, EGCG increased the MTT response of differentiated Caco-2 cells exposed to released NPs in a dose-dependent manner, suggesting a potential mitigation of NP-associated cytotoxicity under the tested in vitro conditions. This study provides new insight into the dynamic interactions between food components and plastic packaging during realistic consumption scenarios, revealing an overlooked pathway influencing human exposure to nanoplastics. The findings expand the current understanding of contaminant release mechanisms at the food-environment interface and inform future strategies for exposure mitigation and sustainable material design to ensure food safety and protect environmental and public health."

Here, we provide compelling evidence that \u03b1-synuclein preformed fibrils (\u03b1-syn PFF) impair lysosomal acidification in microglia, leading to defective autophagic flux and disrupted \u03b1-syn degradation. This dysfunction further promotes the secretion of microglial extracellular vesicles (EVs), exacerbating disease pathology. Mechanistic investigations uncover that \u03b1-syn PFF directly interacts with ATP6V0C, a pivotal V0 subunit of V-ATPase. This interaction sterically hinders V0-V1 domain assembly, disrupting proton pump complex formation and reducing ATP6V0C expression. Functionally, ATP6V0C overexpression rescues lysosomal acidification deficits and facilitates \u03b1-syn degradation in vitro, while in vivo, ATP6V0C overexpression alleviates neurotoxicity and reduces phosphorylated \u03b1-syn aggregation in \u03b1-syn PFF mouse models. Further investigation identifies the PI3K-AKT-mTOR-TFEB pathway as a key regulatory axis of ATP6V0C-mediated lysosomal acidification in microglia. Notably, both TFEB activation and mTOR inhibition restore lysosomal acidity and upregulate ATP6V0C expression, thereby enhancing \u03b1-syn clearance. These findings establish the TFEB-ATP6V0C axis as a key determinant of microglial proteostasis, proposing targeted activation of this pathway as a promising strategy to mitigate PD progression."

Although inhaled NPs rapidly acquire a protein corona that shapes their bioactivity, the consequences of this process in cancer-susceptible lungs remain unclear. Here, we investigated whether NPs form a disease-specific pathogenic protein corona in lung adenocarcinoma that rewires immune signaling and accelerates tumor progression. Polyethylene terephthalate (PET) NPs were generated by mechanical fragmentation and extensively characterized. In tumor-bearing mice, inhaled PET NPs accelerated tumor growth relative to controls. Proteomic analysis of PET NPs incubated with bronchoalveolar lavage fluid from patients with lung adenocarcinoma identified lysozyme (LYZ) as a selectively enriched corona component associated with tumor stage and metastasis. Corona formation induced conformational remodeling of LYZ, enhanced its enzymatic activity, and prolonged its membrane retention. Mechanistically, corona-bound LYZ engaged Toll-like receptor 4 and activated a PGRN-LXR\u03b1 signaling axis, thereby increasing lysosomal acidification-dependent efferocytosis, promoting M2 macrophage polarization, and reducing CD8+ T-cell infiltration. In vivo, AAV9-mediated knockdown of LYZ or PGRN attenuated PET NP-induced efferocytosis, reversed immunosuppressive reprogramming, restored CD8+ T-cell infiltration, and suppressed tumor growth, demonstrating the functional requirement for this corona pathway. These findings establish disease-derived PET NP coronas as active nano-bio interfaces that connect environmental PET NP exposure with efferocytosis-driven immune evasion in lung adenocarcinoma. This work provides a mechanistic link between airborne NPs and tumor progression in susceptible hosts and highlights corona-mediated signaling as a potential therapeutic target and environmental health concern."

Here, we demonstrate that a chimeric peptide (RS-FS), consisting of HCC-targeting RS and nanostructure-forming motifs (FS), self-assembles into nanospheres at neutral pH and transforms into nanofibers under acidic and reductive conditions. These nanofibers specifically localize to tumors and disrupt tumor cell lysosomes, thus enhancing doxorubicin's activity in human HCC cells in vitro and orthotopic HCC mice in vivo after RS-FS-doxorubicin treatment. Importantly, intravenous RS-FS potentiated oral Lenvatinib's antitumor activity up to 61-fold, and eradicated tumors in orthotopic HCC mice via HCC cell-specific lysosome disruption. Potent antitumor effects were also achieved with intravenous RS-FS and oral Epimedium brevicornu Maxim. -derived extracellular vesicles in orthotopic HCC mice, with markedly reduced tumor growth and increased cytotoxic T infiltration, in which RS-FS-mediated lysosome disruption promoted drug release and autophagic flux blockade.

Mesenchymal stem cell-derived nanovesicle-poly(lactic-coglycolic acid) nanoparticles (MSC-PLGA-NPs) were prepared via sonication-loading. Blood-brain barrier (BBB) penetration was evaluated using in vitro transwell models and in vivo mouse models. Lysosomal function, autophagy, pathological protein clearance, and anti-inflammatory effects were assessed using various cellular and molecular biology techniques. MSC-PLGA-NPs demonstrated 2.3-fold higher BBB penetration efficiency compared to PLGA alone. In a chloroquine(CQ)-induced lysosomal injury model and mice model, they effectively restored lysosomal pH, enhanced autophagy (reducing LC3-II/I ratio by 0.4-fold and p62 expression by 52%), cleared amyloid precursor protein (APP) and phosphorylated tau (p-tau) proteins, and inhibited IL-6 and TNF-\u03b1 without hepatorenal toxicity.

Although lysosomal dysfunction is increasingly recognized as a cardinal feature of age-related diseases, most current therapeutic strategies primarily target upstream regulators of autophagy, particularly the PI3K/AKT/mTOR pathway. However, this approach may be limited in aged chondrocytes, where the efficiency of autophagic degradation is already compromised. With ageing, reduced vacuolar ATPase activity and the accumulation of intralysosomal lipofuscin may impair lysosomal acidification and degradative capacity. As a result, even when autophagy is pharmacologically stimulated, the clearance of autophagic cargo remains inefficient. This imbalance leads to the accumulation of undegraded autophagosomes, contributing to cellular stress and impaired autophagic flux. Importantly, lysosomal dysfunction under these conditions has increasingly been associated with the amplification of the senescence-associated secretory phenotype (SASP), activation of the NLRP3 inflammasome, and subsequent macrophage dysregulation. These interconnected processes may further exacerbate joint degeneration in G-OA. This review identifies lysosomal restoration as a potential therapeutic intervention point for overcoming downstream autophagic impairment in G-OA. Enhancing lysosomal acidification and degradative function may help re-establish effective autophagic flux and improve disease outcomes. Although several components of this proposed mechanistic framework require direct experimental validation in aged chondrocytes, the model provides a biologically plausible and testable basis for future investigations into lysosome-targeted therapeutic strategies for G-OA."

Molecular consequences remain poorly understood. Here, we determined transcriptomic changes in S3 segments of male adult DBA wild-type (WT) and littermate diabetic Akita mice \u00b1 Sglt1 knockout (Sglt1-KO) given vehicle or SGLT2i dapagliflozin for 2 wk, and in Akita mice receiving glucagon-like peptide-1 receptor (GLP1R) agonist (GLP1RA) semaglutide. RNA sequencing was performed in S3 segments isolated by immunostaining-guided laser-capture-microdissection in deep cortex/outer medulla. Among 19,068 detected annotated genes, 838 genes were differentially expressed by SGLT2is in WT (differentially expressed genes; DEGs; P < 0.05) and 1,410 genes in Akita vs. WT. Approximately 34% of SGLT2i-sensitive genes changed in the same direction in Akita. Both maneuvers upregulated pathways of cellular proliferation (confirmed by phospho-Ser10 Histone H3 staining) and cellular response to stress, while downregulating pathways of immune/inflammatory response, cytokine production/receptor signaling, and cell adhesion/migration. Both maneuvers also induced unique responses. Unique pathway responses to SGLT2is in WT included an increase in DNA dealkylation/demethylation and lysosomal acidification, and reduced valine biosynthesis. Differences in SGLT1-dependency of responses to Akita vs. SGLT2is in WT suggested different initiating mechanisms. In Akita, SGLT2is, Sglt1-KO, and GLP1R agonism restored 12%, 18%, and 25% of DEGs, respectively; combined SGLT2i/Sglt1-KO was not synergistic. Akita downregulated whole kidney SGLT1 membrane expression, potentially to limit glucose-induced stress. GLP1RA reduced/restored cellular stress response and proliferation in Akita in S3 segments, associated with enhanced/restored kidney membrane expression of SGLT1. Finally, Akita-sensitive genes unresponsive to any of the three maneuvers were identified that may indicate new therapeutic avenues.NEW & NOTEWORTHY Both SGLT2 inhibition and diabetes increase glucose delivery to late proximal tubule S3 segments. Using transcriptomic mapping in mice, we found that both conditions induce cellular proliferation and stress responses while suppressing inflammatory pathways, but also trigger unique responses. Responses differed in their SGLT1-dependency, suggesting different initiating mechanisms. Diabetes suppressed SGLT1 expression, potentially to limit glucose-induced stress. Glucagon-like peptide-1 receptor (GLP1R) agonism reversed many diabetic transcriptomic changes in S3 segments, including stress response, associated with restored SGLT1 expression."

Its silk glands are responsible for the synthesis and secretion of silk proteins. The naked pupa (Nd), a fibroin heavy chain mutant strain of silkworm, was found to exhibit severe atrophy, degeneration of the posterior silk gland (PSG), and abnormal secretion of fibroin proteins, thereby producing little or no silk. Here, we found that the autophagic marker Atg8-PE was upregulated through the target of rapamycin complex 1 signaling pathway in Nd. However, as autophagy substrates, SQSTM1/p62 and ubiquitinated protein levels increased in Nd. Furthermore, treatment with BafA1 showed no effect on the protein levels of SQSTM1/p62, indicating impaired autophagic flux in Nd. Abnormal acidification of lysosomes was further detected, which resulted in a decreased proportion of matured CtsL1 (cathepsin L1). Thus, the substrate in autolysosomes cannot be degraded within a rapid time frame, resulting in the accumulation of protein aggregates, which cause atrophy and degeneration of the PSG. We also found that acidic nanoparticles rescued lysosomal acidification and relieved the degenerative changes of Nd-PSG. The findings of this study suggest that the Nd mutant silkworm can be used as an animal model for studying protein aggregation diseases.Abbreviations: AD: Alzheimer disease; aNP: acidic nanoparticle; APP: amyloid beta precursor protein; Atg8: autophagy related 8; BACE1: beta-secretase 1; BafA1: bafilomycin A1; CtsL1: cathepsin L1; CRY: crystallin; ER: endoplasmic reticulum; FibH: fibroin heavy chain; FibL: fibroin light chain; FUS: FUS RNA binding protein; HD: Huntington disease; HRP: horseradish peroxidase; Nd: naked pupa; OSBPL2: oxysterol binding protein like 2; PD: Parkinson disease; PE: phosphatidylethanolamine; p-EIF4EBP: phosphorylated eukaryotic initiation factor 4E binding protein; PROM1: prominin 1; p-RPS6KB: phosphorylated ribosomal protein S6 kinase B; PSEN: presenilin; PSG: posterior silk gland; SDS-PAGE: sodium dodecyl sulfate-polyacrylamide gel electrophoresis; SEM: standard error of the mean; SOD1: superoxide dismutase 1; SQSTM1/p62: sequestosome 1; TARDBP: TAR DNA binding protein; TORC1: target of rapamycin complex 1; UBQLN2: ubiquilin 2; V-ATPase: vacuolar-type ATPase."

The Ridaifen (RID) compound series comprises structural analogues of tamoxifen that exhibit more potent anticancer activity and have been implicated in modulating autophagy. Here, we investigated how the RID compounds interact with autophagy and explored the factors contributing to their enhanced cytotoxicity. We synthesized RID derivatives containing varying numbers of basic side chains and evaluated their intracellular behavior. We assessed cell viability using an MTT assay and determined lysosomal pH by flow cytometry. To visualize the subcellular distribution of the RID derivative, we employed a fluorescent dye\u2012conjugated form of the compound. Additionally, we monitored autophagic and apoptotic markers through immunoblotting. RID-B demonstrated potent lysosomal neutralization and inhibited autophagic flux near its half-maximal inhibitory concentration. This neutralization led to the accumulation of insoluble SQSTM1-containing aggregates, implicating proteotoxic stress in apoptosis. Confocal imaging revealed proton-dependent lysosomal localization of RID-B, followed by partial cytoplasmic translocation. Notably, co-treatment with bafilomycin A1 reduced RID-B\u2012induced apoptosis, underscoring lysosomal dysfunction initiated apoptotic signaling. Analyses across multiple RID derivatives showed a correlation among the number of basic side chains, lysosomal neutralization, and between lysosomal neutralization and cytotoxicity. Our findings indicate that basic side chains markedly enhance lysosomotropic behavior, enabling sustained autophagy inhibition and apoptosis induction. By revealing a strong link between lysosomal neutralization and proteotoxic cell death, the results suggest that modified tamoxifen analogues, such as RID-B, may offer a promising strategy to overcome autophagy-related drug resistance in cancer therapy."

This study delineates the differential effects of two widely used nanocarriers-mesoporous silica (MSNs) and albumin (ANPs) nanoparticles-on lysosomal biology, with a focus on the expression and activity of cathepsins (CtsB and CtsD), which are key proteases involved in protein degradation and maintaining cellular balance. These two types of nanoparticles, differing in their material and degradability, exhibit distinct behaviors inside the cell. We demonstrate that inorganic MSNs cause significant changes in lysosomal function by altering lysosomal content and cathepsin levels, without triggering lysosomal membrane permeabilization-a typical response to organic particle stress. In contrast, ANPs-which are susceptible to lysosomal cathepsin degradation-induce milder changes in cathepsin expression and maintain lysosomal integrity. Our results highlight that the composition of nanocarriers plays a pivotal role in modulating lysosomal protease activity and maintaining overall cellular homeostasis, highlighting the importance of these parameters in the rational design of drug delivery platforms."

This study identifies a critical protective role for the voltage-gated chloride channel ClC-3, a Cl-/H+ exchanger, in maintaining airway epithelial integrity against oxidative insult. We report significant downregulation of ClC-3 in the bronchial epithelium of chronic bronchitis patients and CS-exposed mice. Using transgenic overexpression and conditional knockout mouse models, we demonstrate that ClC-3 deficiency exacerbates, while its overexpression mitigates, CS-induced airway inflammation, systemic oxidative stress (SOD/MDA), and lung injury. Mechanistically, we show that CS exposure suppresses AKT phosphorylation, leading to the inactivation of the transcription factor CREB1. We validate that CREB1 acts as a direct transcriptional activator of CLCN3 by binding to its promoter; thus, the CS-mediated inhibition of the AKT/CREB1 axis results in transcriptional silencing of ClC-3. At the cellular level, loss of ClC-3 disrupts lysosomal acidification, resulting in a blockade of autophagic flux. This impairment prevents the effective clearance of oxidative damage, thereby promoting epithelial cell death and amplifying inflammatory responses. Collectively, these findings delineate a novel \"CS-AKT/CREB1-ClC-3-Lysosome\" axis, suggesting that restoring ClC-3-mediated lysosomal function represents a promising therapeutic strategy to restore redox balance in chronic bronchitis."

Restoring lysosomal acidity is important for maintaining enzymatic degradation, preventing protein aggregation, and reducing cellular waste accumulation in degenerating tissues. Acidic nanoparticles represent a promising therapeutic strategy to normalize lysosomal pH; however, accurate monitoring of their delivery, retention, and dosage is critical for rigorous evaluation. To address this, we developed fluorescently labeled poly(d,l-lactide-co-glycolide) (PLGA) nanoparticles conjugated with Cyanine3 amine (Cy3). Nanoparticle uptake was systematically optimized, achieving over 90% delivery to lysosomes of induced pluripotent stem cell-derived retinal pigment epithelial (iPS-RPE) cells, although uptake rates varied among adjacent cells. Once internalized, nanoparticles demonstrated remarkable stability, with no detectable change in concentration, distribution, or size for at least 28 days. iPS-RPE cells exhibited higher nanoparticle internalization compared with the ARPE-19 cell line and optic nerve head astrocytes. The capacity of the nanoparticles to restore function to stressed lysosomes was confirmed by their ability to reacidify lysosomes, restore cathepsin B activity, and increase the levels of active cathepsin D. The nanoparticles also reduced the levels of LC3II in astrocytes treated with chloroquine, indicating that they can also restore autophagy rates. In summary, this study demonstrates the value of Cy3 labeling for enhanced nanoparticle tracking to lysosomes. The findings also identify PLGA nanoparticles as powerful tools for restoring degradative lysosomal function and autophagy in cells undergoing lysosomal stress.NEW & NOTEWORTHY Tools that restore acidic pH in compromised lysosomes can enhance autophagy and waste clearance in degenerative disorders characterized by excessive accumulation. Here, we describe the synthesis of lysosome-targeted nanoparticles composed of poly(d,l-lactide-co-glycolide) (PLGA) polymers covalently bound to the fluorescent dye Cyanine3 amine (Cy3). These Cy3-PLGA nanoparticles enable precise tracking of lysosomal delivery and demonstrate sustained long-term retention within lysosomes, supporting their potential for future applications aimed at restoring lysosomal pH in aging and degenerating diseases."

However, whether NPs induce renal fibrosis remains contentious, and the reversibility of NPs-triggered nephrotoxicity has rarely been reported. This study investigated the role of lysosomes in renal fibrosis induced by low-level polystyrene (PS) NPs with particle sizes of 100 and 500 nm (PS100 and PS500) in mice using Masson staining, immunohistochemistry, Western blotting, fluorescence imaging, and other techniques. The results showed that PS100 induced more pronounced renal fibrosis than PS500. Mechanistically, PS NPs promoted autophagosome formation accompanied by the inhibition of autophagic degradation. Moreover, PS NPs impaired lysosomal degradation function, evidenced by reduced CTSB and CTSD protein levels. This impairment blocked autophagic flux, thereby inducing renal fibrosis, which was further confirmed by in vitro results. Notably, lysosomal exocytosis plays a crucial role in the clearance of NPs from mouse kidneys through activating Mcoln1 expression, which contributes to restoring autophagic flux and alleviating renal fibrosis during recovery. Collectively, our findings provide the first evidence that lysosomes serve dual functions in the persistence and reversibility of NPs-induced nephrotoxicity, which could be valuable for the intervention and mitigation of kidney damage resulting from environmental NPs exposure."

Environmental toxins are considered the main etiological factor. The increasing use of polystyrene nanoparticles (PS-NPs) has raised concerns about their potential neurotoxic effects in PD. This study aimed to investigate the impact of PS-NPs on the onset and progression of PD and the underlying mechanisms. The breach of the blood-brain barrier (BBB) by PS-NPs was assessed using bioluminescence imaging, fluorescence observation, Pyrolysis-Gas Chromatography-Mass Spectrometry (Py-GCMs), transmission electron microscope (TEM), and Evans blue staining. To evaluate the potential promotion of PD by PS-NPs, a 30-day repeated oral administration study was conducted in vivo, during which behavioral changes and alterations in dopaminergic neurons in the substantia nigra were assessed. In vitro cytotoxicity assays were performed following PS-NPs intervention. Molecular biology techniques, including Western blotting and immunofluorescence, were employed to analyze proteins related to pyroptosis and autophagy-lysosomal pathway in both in vivo and in vitro settings. Additionally, proteomic sequencing was utilized to identify the upstream regulator of the autophagy-lysosomal pathway (ALP), and the effects of modulating this target protein on the ALP-pyroptosis pathway were analyzed. Bioluminescence imaging and Py-GCMs confirmed that PS-NPs entered the brain within 1.5\u00a0h. Evans blue staining and TEM showed PS-NPs damaged the BBB. The 30-day oral toxicity revealed that PS-NPs exacerbated behavioral abnormalities and caused dopaminergic neuron loss. Western blotting and immunofluorescence indicated that PS-NPs induced pyroptosis, disrupted autophagic flux, and lowered protein levels involved in autophagosome-lysosome fusion, both in vivo and in vitro. Furthermore, PS-NPs activated the mechanistic target of rapamycin (mTOR) and inhibited the nuclear translocation of Transcription Factor EB (TFEB). Proteomic sequencing identified a deficit of Tuberous Sclerosis Complex (TSC) 2 protein within the mTOR pathway. Immuno-coprecipitation and Coomassie Blue Fast Staining revealed that PS-NPs bound to TSC2 protein, causing disassembly of TSC1-TSC2 complex. These findings underscore how PS-NPs accelerated PD onset and progression by disrupting autophagosome-lysosome fusion through TSC2-mTOR-TFEB axis, which triggered protein degradation disorders and pyroptosis in dopaminergic neurons. The molecular mechanisms could inform environmental safety regulations concerning nanoplastics and inspire therapeutic strategies for PD."

This dysfunction further promotes the secretion of microglial extracellular vesicles (EVs), exacerbating disease pathology. Mechanistic investigations uncover that \u03b1-syn PFF directly interacts with ATP6V0C, a pivotal V0 subunit of V-ATPase. This interaction sterically hinders V0-V1 domain assembly, disrupting proton pump complex formation and reducing ATP6V0C expression.

Although lysosomal dysfunction is increasingly recognized as a cardinal feature of age-related diseases, most current therapeutic strategies primarily target upstream regulators of autophagy, particularly the PI3K/AKT/mTOR pathway. However, this approach may be limited in aged chondrocytes, where the efficiency of autophagic degradation is already compromised. With ageing, reduced vacuolar ATPase activity and the accumulation of intralysosomal lipofuscin may impair lysosomal acidification and degradative capacity. As a result, even when autophagy is pharmacologically stimulated, the clearance of autophagic cargo remains inefficient. This imbalance leads to the accumulation of undegraded autophagosomes, contributing to cellular stress and impaired autophagic flux. Importantly, lysosomal dysfunction under these conditions has increasingly been associated with the amplification of the senescence-associated secretory phenotype (SASP), activation of the NLRP3 inflammasome, and subsequent macrophage dysregulation. These interconnected processes may further exacerbate joint degeneration in G-OA. This review identifies lysosomal restoration as a potential therapeutic intervention point for overcoming downstream autophagic impairment in G-OA. Enhancing lysosomal acidification and degradative function may help re-establish effective autophagic flux and improve disease outcomes. Although several components of this proposed mechanistic framework require direct experimental validation in aged chondrocytes, the model provides a biologically plausible and testable basis for future investigations into lysosome-targeted therapeutic strategies for G-OA."

RNA sequencing was performed in S3 segments isolated by immunostaining-guided laser-capture-microdissection in deep cortex/outer medulla. Among 19,068 detected annotated genes, 838 genes were differentially expressed by SGLT2is in WT (differentially expressed genes; DEGs; P < 0.05) and 1,410 genes in Akita vs. WT. Approximately 34% of SGLT2i-sensitive genes changed in the same direction in Akita.

Unique pathway responses to SGLT2is in WT included an increase in DNA dealkylation/demethylation and lysosomal acidification, and reduced valine biosynthesis.

Its silk glands are responsible for the synthesis and secretion of silk proteins. The naked pupa (Nd), a fibroin heavy chain mutant strain of silkworm, was found to exhibit severe atrophy, degeneration of the posterior silk gland (PSG), and abnormal secretion of fibroin proteins, thereby producing little or no silk. Here, we found that the autophagic marker Atg8-PE was upregulated through the target of rapamycin complex 1 signaling pathway in Nd. However, as autophagy substrates, SQSTM1/p62 and ubiquitinated protein levels increased in Nd. Furthermore, treatment with BafA1 showed no effect on the protein levels of SQSTM1/p62, indicating impaired autophagic flux in Nd. Abnormal acidification of lysosomes was further detected, which resulted in a decreased proportion of matured CtsL1 (cathepsin L1). Thus, the substrate in autolysosomes cannot be degraded within a rapid time frame, resulting in the accumulation of protein aggregates, which cause atrophy and degeneration of the PSG. We also found that acidic nanoparticles rescued lysosomal acidification and relieved the degenerative changes of Nd-PSG.

Here, we investigated how the RID compounds interact with autophagy and explored the factors contributing to their enhanced cytotoxicity. We synthesized RID derivatives containing varying numbers of basic side chains and evaluated their intracellular behavior. We assessed cell viability using an MTT assay and determined lysosomal pH by flow cytometry. To visualize the subcellular distribution of the RID derivative, we employed a fluorescent dye\u2012conjugated form of the compound. Additionally, we monitored autophagic and apoptotic markers through immunoblotting. RID-B demonstrated potent lysosomal neutralization and inhibited autophagic flux near its half-maximal inhibitory concentration. This neutralization led to the accumulation of insoluble SQSTM1-containing aggregates, implicating proteotoxic stress in apoptosis.

This study identifies a critical protective role for the voltage-gated chloride channel ClC-3, a Cl-/H+ exchanger, in maintaining airway epithelial integrity against oxidative insult. We report significant downregulation of ClC-3 in the bronchial epithelium of chronic bronchitis patients and CS-exposed mice. Using transgenic overexpression and conditional knockout mouse models, we demonstrate that ClC-3 deficiency exacerbates, while its overexpression mitigates, CS-induced airway inflammation, systemic oxidative stress (SOD/MDA), and lung injury. Mechanistically, we show that CS exposure suppresses AKT phosphorylation, leading to the inactivation of the transcription factor CREB1. We validate that CREB1 acts as a direct transcriptional activator of CLCN3 by binding to its promoter; thus, the CS-mediated inhibition of the AKT/CREB1 axis results in transcriptional silencing of ClC-3.

Following a general overview of the main uptake pathways of nanoparticles and the subsequent intracellular localization, a comprehensive analysis of the BGNs' internalization process is presented. Key findings reveal that the BGNs are mainly internalized by active transport mechanisms and are entrapped in endosomes/lysosomes, limiting their ability to exert their full intracellular therapeutic potential. Existing studies in the literature provide valuable data to correlate the uptake process with the intracellular BGN localization, but there is limited research on the fate of BGNs and the released ions once entrapped in intracellular vesicles.

This narrative review addresses that gap from an environmental microbiology perspective, synthesizing recent literature on periodontal disease, chronic low-grade inflammation, oral biofilms, dental materials, microbial-plastic interactions, and systemic chronic disease risk. Unlike prior reviews, we apply an explicit three-tier evidentiary framework (established, plausible, unproven) that distinguishes what is directly demonstrated from what is biologically plausible but unproven, and we situate the periodontal environment specifically as a particle-retention and inflammatory-amplification niche. The strongest direct oral evidence shows that human dental calculus harbors at least 26 microplastic types, dominated by polyamide (41.4%), polyethylene (32.7%), and polyurethane (7.0%). Polyethylene isolated from calculus induces cytotoxicity, apoptosis, impaired migration, NF-\u03baB activation, and upregulation of IL-1\u03b2 and IL-6 in human gingival fibroblasts. From a microbiological standpoint, oral organisms actively degrade methacrylate dental polymers, and the degradation products of these polymers reciprocally modulate oral bacterial virulence gene expression. Across experimental systems, MNPs activate oxidative stress, inflammasome signaling, macrophage polarization, and barrier dysfunction, pathways that overlap extensively with periodontal pathobiology. Adjacent environmental microbiology demonstrates that plastic-associated biofilms enhance extracellular polymeric substance production, quorum sensing, pathogen persistence, and antibiotic resistance gene transfer, supporting a plausible but not yet validated oral plastisphere within plaque and calculus. We argue that periodontitis should be reconceptualized as a chronically inflamed particle-processing interface that may increase local MNP retention, cellular reactivity, and systemic inflammatory spillover, with implications for cardiovascular, metabolic, and other chronic disease risk pathways. Current evidence does not yet prove that environmental MNP exposure causes human periodontitis, and that evidentiary boundary is maintained throughout. A priority research agenda is proposed, centered on contamination-controlled subgingival biomonitoring stratified by periodontal status, spatially resolved multi-species biofilm models, polymer source attribution, and longitudinal clinical studies linking oral plastic burden to inflammatory and systemic outcomes."

The acidic pH inside the lysosome (vacuole in yeast) is essential for cellular content degradation, signaling, and autophagy. Defects in lysosome/vacuole acidification are a conserved hallmark of aging and age-related diseases. Traditionally, the lysosome/vacuole is thought to import free protons (H\u207a) from the surrounding neutral cytosol. Here, we uncovered a conserved lysosome/vacuole acidification mechanism from yeast to human involving lysosomal/vacuolar uptake of H+ pumped out by mitochondrial electron transport chain through mitochondria-lysosomes/vacuoles membrane contacts. Aging/senescence-associated disruption of mitochondria-lysosome/vacuole contacts causes lysosomal/vacuolar de-acidification, which can be reversed by either expressing an engineered linker to connect these two organelles or through an asymmetry-dependent rejuvenation process in daughter cells. Preserving lysosomal acidification in senescent human cells prevents the induction of major senescence-associated secretory phenotype factors and restores autophagic flux. These findings reshape our current understanding of the mechanisms underlying lysosomal/vacuolar (de-)acidification in both young and aged/senescent cells."

This direct and efficient delivery strategy not only has transformative potential for IVDD therapy but also broadens the conceptual and methodological framework for precision miRNA-based therapeutics."

Herein, we developed a nano-delivery system, designated as CEL-TPP@siSurvivin/TDNP NPs, consisting of a self-assembled nanocore formed by triphenylphosphine (TPP)-modified celastrol (CEL) and siSurvivin, encapsulated within turmeric-derived nanoparticles (TDNPs), for effective tumor treatment through a combined chemotherapy and gene therapy approach. The TPP modification confers mitochondrial targeting capability to CEL, which acts combinedly with siSurvivin-mediated gene silencing to significantly enhance tumor cell apoptosis. Notably, once the NPs enter cells and become sequestered within lysosomes, they induce the upregulation of the V-ATPase subunits ATP6V1A/ATP6V1G1. It hyperactivates lysosomal proton pumps, driving excessive acidification of the lysosomal lumen, which in turn facilitates NPs escape and ultimately enhances the silencing efficiency of the delivered siSurvivin. Furthermore, in vivo studies validated that the nano-delivery system exhibits potent antitumor efficacy in a 4T1 murine breast cancer model while maintaining a favorable biosafety profile. This study presents a novel strategy to overcome the lysosomal escape challenge in nanomedicine, while also establishing an efficient and low-toxicity delivery platform for combined chemotherapy and gene therapy with promising clinical translation prospects."

In vitro, all MNP types were internalized by human corneal epithelial (HCE-T) cells with perinuclear accumulation and induced dose- and time-dependent cytotoxicity, including reduced viability, increased ROS, elevated TUNEL positivity, ZO-1 downregulation, and impaired epithelial migration; notably, 80\u202fnm PS MNPs elicited stronger early toxicity. In vivo, chronic topical exposure produced corneal epithelial damage, tear-film instability, conjunctival goblet-cell depletion, reduced corneal nerve density, and lacrimal gland inflammatory activation. Live imaging and scanning electron microscopy confirmed deposition, with Fiber MNPs showing surface embedding and disruption of corneal epithelial microvillar microarchitecture. Transcriptomic profiling with in vitro/in vivo validation showed enrichment of MAPK signaling and activation-associated changes in the MAP3K8-ERK/JNK/p38 axis, accompanied by a sustained pro-inflammatory transcriptional program, with more persistent inflammatory signaling in the Fiber MNP group.

Here, we demonstrate that a chimeric peptide (RS-FS), consisting of HCC-targeting RS and nanostructure-forming motifs (FS), self-assembles into nanospheres at neutral pH and transforms into nanofibers under acidic and reductive conditions. These nanofibers specifically localize to tumors and disrupt tumor cell lysosomes, thus enhancing doxorubicin's activity in human HCC cells in vitro and orthotopic HCC mice in vivo after RS-FS-doxorubicin treatment.

This study investigated the effects of polystyrene (PS) NPs on steatosis and fatty liver disease. PS-NP oral administration, in conjunction with a high-fat diet (HFD), synergistically exacerbated the symptoms of steatosis in mice, leading to increased alanine transaminase, aspartate aminotransferase, and cholesterol levels; no effects were observed with PS-NPs on a normal chow diet. Transcriptome analysis unveiled that PS-NPs interfered with actin organization, cell-cell adhesion, PPAR signaling, and lipid metabolism. In HepaRG cells, PS-NPs rapidly entered by inducing actin rearrangement, resulting in the formation of numerous small cytoplasmic vesicles. This treatment led to an augmented number of acidic organelles, leading to development and buildup of large vacuoles, indicative of enlarged pre-lysosomal and lysosomal compartments. PS-NP exposure hampered p62 degradation, leading to LC3B accumulation and decreased cathepsin B and D activity. Additionally, PS-NP exposure resulted in accumulation of lipid droplets and elevated expression of lipogenesis-, transport-, and storage-related genes.

Protopanaxadiol (PPD), protopanaxatriol (PPT), and ginsenoside Rh2 (GR2) were chosen because their dammarane skeleton preserves membrane-insertion capacity for endosomal escape, whereas bulkier multi-glycosylated ginsenosides adversely affect LNP size and stability. In this study, we designed novel inhaled LNPs incorporating ginseng-derived cholesterol analogs to enhance therapeutic efficacy against asthma. PPD and PPT were used as membrane components to formulate anti-MUC5AC siRNA-loaded LNPs (designated as DLNPs and TLNPs). Flow cytometry and confocal laser scanning microscopy (CLSM) were employed to evaluate the cellular uptake and lysosomal escape of LNPs. An asthmatic mouse model was established to assess therapeutic effects of DLNPs and TLNPs through pathological section analysis and determination of inflammatory cytokine levels. The data showed that these novel formulations enhanced cellular uptake by airway epithelial cells (AECs) and promoted siRNA escape from lysosomes, thereby improving pulmonary delivery efficiency.

Restoring lysosomal acidity is important for maintaining enzymatic degradation, preventing protein aggregation, and reducing cellular waste accumulation in degenerating tissues. Acidic nanoparticles represent a promising therapeutic strategy to normalize lysosomal pH; however, accurate monitoring of their delivery, retention, and dosage is critical for rigorous evaluation. To address this, we developed fluorescently labeled poly(d,l-lactide-co-glycolide) (PLGA) nanoparticles conjugated with Cyanine3 amine (Cy3). Nanoparticle uptake was systematically optimized, achieving over 90% delivery to lysosomes of induced pluripotent stem cell-derived retinal pigment epithelial (iPS-RPE) cells, although uptake rates varied among adjacent cells. Once internalized, nanoparticles demonstrated remarkable stability, with no detectable change in concentration, distribution, or size for at least 28 days. iPS-RPE cells exhibited higher nanoparticle internalization compared with the ARPE-19 cell line and optic nerve head astrocytes. The capacity of the nanoparticles to restore function to stressed lysosomes was confirmed by their ability to reacidify lysosomes, restore cathepsin B activity, and increase the levels of active cathepsin D. The nanoparticles also reduced the levels of LC3II in astrocytes treated with chloroquine, indicating that they can also restore autophagy rates. In summary, this study demonstrates the value of Cy3 labeling for enhanced nanoparticle tracking to lysosomes. The findings also identify PLGA nanoparticles as powerful tools for restoring degradative lysosomal function and autophagy in cells undergoing lysosomal stress.NEW & NOTEWORTHY Tools that restore acidic pH in compromised lysosomes can enhance autophagy and waste clearance in degenerative disorders characterized by excessive accumulation.

These Cy3-PLGA nanoparticles enable precise tracking of lysosomal delivery and demonstrate sustained long-term retention within lysosomes, supporting their potential for future applications aimed at restoring lysosomal pH in aging and degenerating diseases."

However, whether NPs induce renal fibrosis remains contentious, and the reversibility of NPs-triggered nephrotoxicity has rarely been reported. This study investigated the role of lysosomes in renal fibrosis induced by low-level polystyrene (PS) NPs with particle sizes of 100 and 500 nm (PS100 and PS500) in mice using Masson staining, immunohistochemistry, Western blotting, fluorescence imaging, and other techniques. The results showed that PS100 induced more pronounced renal fibrosis than PS500. Mechanistically, PS NPs promoted autophagosome formation accompanied by the inhibition of autophagic degradation. Moreover, PS NPs impaired lysosomal degradation function, evidenced by reduced CTSB and CTSD protein levels. This impairment blocked autophagic flux, thereby inducing renal fibrosis, which was further confirmed by in vitro results. Notably, lysosomal exocytosis plays a crucial role in the clearance of NPs from mouse kidneys through activating Mcoln1 expression, which contributes to restoring autophagic flux and alleviating renal fibrosis during recovery. Collectively, our findings provide the first evidence that lysosomes serve dual functions in the persistence and reversibility of NPs-induced nephrotoxicity, which could be valuable for the intervention and mitigation of kidney damage resulting from environmental NPs exposure."

Environmental toxins are considered the main etiological factor. The increasing use of polystyrene nanoparticles (PS-NPs) has raised concerns about their potential neurotoxic effects in PD. This study aimed to investigate the impact of PS-NPs on the onset and progression of PD and the underlying mechanisms. The breach of the blood-brain barrier (BBB) by PS-NPs was assessed using bioluminescence imaging, fluorescence observation, Pyrolysis-Gas Chromatography-Mass Spectrometry (Py-GCMs), transmission electron microscope (TEM), and Evans blue staining. To evaluate the potential promotion of PD by PS-NPs, a 30-day repeated oral administration study was conducted in vivo, during which behavioral changes and alterations in dopaminergic neurons in the substantia nigra were assessed. In vitro cytotoxicity assays were performed following PS-NPs intervention. Molecular biology techniques, including Western blotting and immunofluorescence, were employed to analyze proteins related to pyroptosis and autophagy-lysosomal pathway in both in vivo and in vitro settings. Additionally, proteomic sequencing was utilized to identify the upstream regulator of the autophagy-lysosomal pathway (ALP), and the effects of modulating this target protein on the ALP-pyroptosis pathway were analyzed. Bioluminescence imaging and Py-GCMs confirmed that PS-NPs entered the brain within 1.5\u00a0h. Evans blue staining and TEM showed PS-NPs damaged the BBB. The 30-day oral toxicity revealed that PS-NPs exacerbated behavioral abnormalities and caused dopaminergic neuron loss. Western blotting and immunofluorescence indicated that PS-NPs induced pyroptosis, disrupted autophagic flux, and lowered protein levels involved in autophagosome-lysosome fusion, both in vivo and in vitro. Furthermore, PS-NPs activated the mechanistic target of rapamycin (mTOR) and inhibited the nuclear translocation of Transcription Factor EB (TFEB). Proteomic sequencing identified a deficit of Tuberous Sclerosis Complex (TSC) 2 protein within the mTOR pathway. Immuno-coprecipitation and Coomassie Blue Fast Staining revealed that PS-NPs bound to TSC2 protein, causing disassembly of TSC1-TSC2 complex. These findings underscore how PS-NPs accelerated PD onset and progression by disrupting autophagosome-lysosome fusion through TSC2-mTOR-TFEB axis, which triggered protein degradation disorders and pyroptosis in dopaminergic neurons. The molecular mechanisms could inform environmental safety regulations concerning nanoplastics and inspire therapeutic strategies for PD."

Mechanistic investigations uncover that \u03b1-syn PFF directly interacts with ATP6V0C, a pivotal V0 subunit of V-ATPase. This interaction sterically hinders V0-V1 domain assembly, disrupting proton pump complex formation and reducing ATP6V0C expression.

Although lysosomal dysfunction is increasingly recognized as a cardinal feature of age-related diseases, most current therapeutic strategies primarily target upstream regulators of autophagy, particularly the PI3K/AKT/mTOR pathway. However, this approach may be limited in aged chondrocytes, where the efficiency of autophagic degradation is already compromised. With ageing, reduced vacuolar ATPase activity and the accumulation of intralysosomal lipofuscin may impair lysosomal acidification and degradative capacity. As a result, even when autophagy is pharmacologically stimulated, the clearance of autophagic cargo remains inefficient. This imbalance leads to the accumulation of undegraded autophagosomes, contributing to cellular stress and impaired autophagic flux. Importantly, lysosomal dysfunction under these conditions has increasingly been associated with the amplification of the senescence-associated secretory phenotype (SASP), activation of the NLRP3 inflammasome, and subsequent macrophage dysregulation. These interconnected processes may further exacerbate joint degeneration in G-OA. This review identifies lysosomal restoration as a potential therapeutic intervention point for overcoming downstream autophagic impairment in G-OA. Enhancing lysosomal acidification and degradative function may help re-establish effective autophagic flux and improve disease outcomes. Although several components of this proposed mechanistic framework require direct experimental validation in aged chondrocytes, the model provides a biologically plausible and testable basis for future investigations into lysosome-targeted therapeutic strategies for G-OA."

Its silk glands are responsible for the synthesis and secretion of silk proteins. The naked pupa (Nd), a fibroin heavy chain mutant strain of silkworm, was found to exhibit severe atrophy, degeneration of the posterior silk gland (PSG), and abnormal secretion of fibroin proteins, thereby producing little or no silk. Here, we found that the autophagic marker Atg8-PE was upregulated through the target of rapamycin complex 1 signaling pathway in Nd. However, as autophagy substrates, SQSTM1/p62 and ubiquitinated protein levels increased in Nd. Furthermore, treatment with BafA1 showed no effect on the protein levels of SQSTM1/p62, indicating impaired autophagic flux in Nd. Abnormal acidification of lysosomes was further detected, which resulted in a decreased proportion of matured CtsL1 (cathepsin L1). Thus, the substrate in autolysosomes cannot be degraded within a rapid time frame, resulting in the accumulation of protein aggregates, which cause atrophy and degeneration of the PSG. We also found that acidic nanoparticles rescued lysosomal acidification and relieved the degenerative changes of Nd-PSG.

Notably, co-treatment with bafilomycin A1 reduced RID-B\u2012induced apoptosis, underscoring lysosomal dysfunction initiated apoptotic signaling. Analyses across multiple RID derivatives showed a correlation among the number of basic side chains, lysosomal neutralization, and between lysosomal neutralization and cytotoxicity. Our findings indicate that basic side chains markedly enhance lysosomotropic behavior, enabling sustained autophagy inhibition and apoptosis induction. By revealing a strong link between lysosomal neutralization and proteotoxic cell death, the results suggest that modified tamoxifen analogues, such as RID-B, may offer a promising strategy to overcome autophagy-related drug resistance in cancer therapy."

This study identifies a critical protective role for the voltage-gated chloride channel ClC-3, a Cl-/H+ exchanger, in maintaining airway epithelial integrity against oxidative insult. We report significant downregulation of ClC-3 in the bronchial epithelium of chronic bronchitis patients and CS-exposed mice. Using transgenic overexpression and conditional knockout mouse models, we demonstrate that ClC-3 deficiency exacerbates, while its overexpression mitigates, CS-induced airway inflammation, systemic oxidative stress (SOD/MDA), and lung injury. Mechanistically, we show that CS exposure suppresses AKT phosphorylation, leading to the inactivation of the transcription factor CREB1. We validate that CREB1 acts as a direct transcriptional activator of CLCN3 by binding to its promoter; thus, the CS-mediated inhibition of the AKT/CREB1 axis results in transcriptional silencing of ClC-3. At the cellular level, loss of ClC-3 disrupts lysosomal acidification, resulting in a blockade of autophagic flux. This impairment prevents the effective clearance of oxidative damage, thereby promoting epithelial cell death and amplifying inflammatory responses. Collectively, these findings delineate a novel \"CS-AKT/CREB1-ClC-3-Lysosome\" axis, suggesting that restoring ClC-3-mediated lysosomal function represents a promising therapeutic strategy to restore redox balance in chronic bronchitis."

However, the intracellular efficiency of BGNs is limited by the internalization mechanism, further dictating the intracellular trafficking and fate. Following a general overview of the main uptake pathways of nanoparticles and the subsequent intracellular localization, a comprehensive analysis of the BGNs' internalization process is presented. Key findings reveal that the BGNs are mainly internalized by active transport mechanisms and are entrapped in endosomes/lysosomes, limiting their ability to exert their full intracellular therapeutic potential. Existing studies in the literature provide valuable data to correlate the uptake process with the intracellular BGN localization, but there is limited research on the fate of BGNs and the released ions once entrapped in intracellular vesicles. Therefore, in the last part, future strategies to either escape the endosome or use the lysosomal degradation as a mechanism for controlled intracellular ion release with implications for targeted modulation of cell behavior are discussed. Going beyond BGNs, this review highlights the need of understanding better the dynamically transforming degradable nanoparticles - an essential step toward achieving their full intracellular therapeutic potential."

This narrative review addresses that gap from an environmental microbiology perspective, synthesizing recent literature on periodontal disease, chronic low-grade inflammation, oral biofilms, dental materials, microbial-plastic interactions, and systemic chronic disease risk. Unlike prior reviews, we apply an explicit three-tier evidentiary framework (established, plausible, unproven) that distinguishes what is directly demonstrated from what is biologically plausible but unproven, and we situate the periodontal environment specifically as a particle-retention and inflammatory-amplification niche. The strongest direct oral evidence shows that human dental calculus harbors at least 26 microplastic types, dominated by polyamide (41.4%), polyethylene (32.7%), and polyurethane (7.0%). Polyethylene isolated from calculus induces cytotoxicity, apoptosis, impaired migration, NF-\u03baB activation, and upregulation of IL-1\u03b2 and IL-6 in human gingival fibroblasts. From a microbiological standpoint, oral organisms actively degrade methacrylate dental polymers, and the degradation products of these polymers reciprocally modulate oral bacterial virulence gene expression. Across experimental systems, MNPs activate oxidative stress, inflammasome signaling, macrophage polarization, and barrier dysfunction, pathways that overlap extensively with periodontal pathobiology. Adjacent environmental microbiology demonstrates that plastic-associated biofilms enhance extracellular polymeric substance production, quorum sensing, pathogen persistence, and antibiotic resistance gene transfer, supporting a plausible but not yet validated oral plastisphere within plaque and calculus. We argue that periodontitis should be reconceptualized as a chronically inflamed particle-processing interface that may increase local MNP retention, cellular reactivity, and systemic inflammatory spillover, with implications for cardiovascular, metabolic, and other chronic disease risk pathways. Current evidence does not yet prove that environmental MNP exposure causes human periodontitis, and that evidentiary boundary is maintained throughout. A priority research agenda is proposed, centered on contamination-controlled subgingival biomonitoring stratified by periodontal status, spatially resolved multi-species biofilm models, polymer source attribution, and longitudinal clinical studies linking oral plastic burden to inflammatory and systemic outcomes."

The acidic pH inside the lysosome (vacuole in yeast) is essential for cellular content degradation, signaling, and autophagy. Defects in lysosome/vacuole acidification are a conserved hallmark of aging and age-related diseases. Traditionally, the lysosome/vacuole is thought to import free protons (H\u207a) from the surrounding neutral cytosol. Here, we uncovered a conserved lysosome/vacuole acidification mechanism from yeast to human involving lysosomal/vacuolar uptake of H+ pumped out by mitochondrial electron transport chain through mitochondria-lysosomes/vacuoles membrane contacts. Aging/senescence-associated disruption of mitochondria-lysosome/vacuole contacts causes lysosomal/vacuolar de-acidification, which can be reversed by either expressing an engineered linker to connect these two organelles or through an asymmetry-dependent rejuvenation process in daughter cells. Preserving lysosomal acidification in senescent human cells prevents the induction of major senescence-associated secretory phenotype factors and restores autophagic flux. These findings reshape our current understanding of the mechanisms underlying lysosomal/vacuolar (de-)acidification in both young and aged/senescent cells."

Herein, we developed a nano-delivery system, designated as CEL-TPP@siSurvivin/TDNP NPs, consisting of a self-assembled nanocore formed by triphenylphosphine (TPP)-modified celastrol (CEL) and siSurvivin, encapsulated within turmeric-derived nanoparticles (TDNPs), for effective tumor treatment through a combined chemotherapy and gene therapy approach. The TPP modification confers mitochondrial targeting capability to CEL, which acts combinedly with siSurvivin-mediated gene silencing to significantly enhance tumor cell apoptosis. Notably, once the NPs enter cells and become sequestered within lysosomes, they induce the upregulation of the V-ATPase subunits ATP6V1A/ATP6V1G1. It hyperactivates lysosomal proton pumps, driving excessive acidification of the lysosomal lumen, which in turn facilitates NPs escape and ultimately enhances the silencing efficiency of the delivered siSurvivin. Furthermore, in vivo studies validated that the nano-delivery system exhibits potent antitumor efficacy in a 4T1 murine breast cancer model while maintaining a favorable biosafety profile. This study presents a novel strategy to overcome the lysosomal escape challenge in nanomedicine, while also establishing an efficient and low-toxicity delivery platform for combined chemotherapy and gene therapy with promising clinical translation prospects."

Here, we demonstrate that a chimeric peptide (RS-FS), consisting of HCC-targeting RS and nanostructure-forming motifs (FS), self-assembles into nanospheres at neutral pH and transforms into nanofibers under acidic and reductive conditions. These nanofibers specifically localize to tumors and disrupt tumor cell lysosomes, thus enhancing doxorubicin's activity in human HCC cells in vitro and orthotopic HCC mice in vivo after RS-FS-doxorubicin treatment. Importantly, intravenous RS-FS potentiated oral Lenvatinib's antitumor activity up to 61-fold, and eradicated tumors in orthotopic HCC mice via HCC cell-specific lysosome disruption. Potent antitumor effects were also achieved with intravenous RS-FS and oral Epimedium brevicornu Maxim. -derived extracellular vesicles in orthotopic HCC mice, with markedly reduced tumor growth and increased cytotoxic T infiltration, in which RS-FS-mediated lysosome disruption promoted drug release and autophagic flux blockade.

This study investigated the effects of polystyrene (PS) NPs on steatosis and fatty liver disease. PS-NP oral administration, in conjunction with a high-fat diet (HFD), synergistically exacerbated the symptoms of steatosis in mice, leading to increased alanine transaminase, aspartate aminotransferase, and cholesterol levels; no effects were observed with PS-NPs on a normal chow diet. Transcriptome analysis unveiled that PS-NPs interfered with actin organization, cell-cell adhesion, PPAR signaling, and lipid metabolism. In HepaRG cells, PS-NPs rapidly entered by inducing actin rearrangement, resulting in the formation of numerous small cytoplasmic vesicles. This treatment led to an augmented number of acidic organelles, leading to development and buildup of large vacuoles, indicative of enlarged pre-lysosomal and lysosomal compartments. PS-NP exposure hampered p62 degradation, leading to LC3B accumulation and decreased cathepsin B and D activity. Additionally, PS-NP exposure resulted in accumulation of lipid droplets and elevated expression of lipogenesis-, transport-, and storage-related genes. These findings suggest that excessive endocytosis driven by PS-NPs worsens MASLD in HFD through accumulation of lysosomes and large vacuoles with reduced cathepsin activity."

Protopanaxadiol (PPD), protopanaxatriol (PPT), and ginsenoside Rh2 (GR2) were chosen because their dammarane skeleton preserves membrane-insertion capacity for endosomal escape, whereas bulkier multi-glycosylated ginsenosides adversely affect LNP size and stability. In this study, we designed novel inhaled LNPs incorporating ginseng-derived cholesterol analogs to enhance therapeutic efficacy against asthma. PPD and PPT were used as membrane components to formulate anti-MUC5AC siRNA-loaded LNPs (designated as DLNPs and TLNPs). Flow cytometry and confocal laser scanning microscopy (CLSM) were employed to evaluate the cellular uptake and lysosomal escape of LNPs. An asthmatic mouse model was established to assess therapeutic effects of DLNPs and TLNPs through pathological section analysis and determination of inflammatory cytokine levels. The data showed that these novel formulations enhanced cellular uptake by airway epithelial cells (AECs) and promoted siRNA escape from lysosomes, thereby improving pulmonary delivery efficiency. TLNPs, in particular, demonstrated superior performance. Furthermore, DLNPs and TLNPs exerted multifaceted anti\u2011asthmatic effects in vivo, as evidenced by significant suppression of MUC5AC overexpression in AECs, attenuation of inflammatory cell infiltration, and reduction in the secretion of the critical cytokines IL\u20114 and IL\u201113.

Although inhaled NPs rapidly acquire a protein corona that shapes their bioactivity, the consequences of this process in cancer-susceptible lungs remain unclear. Here, we investigated whether NPs form a disease-specific pathogenic protein corona in lung adenocarcinoma that rewires immune signaling and accelerates tumor progression. Polyethylene terephthalate (PET) NPs were generated by mechanical fragmentation and extensively characterized. In tumor-bearing mice, inhaled PET NPs accelerated tumor growth relative to controls. Proteomic analysis of PET NPs incubated with bronchoalveolar lavage fluid from patients with lung adenocarcinoma identified lysozyme (LYZ) as a selectively enriched corona component associated with tumor stage and metastasis. Corona formation induced conformational remodeling of LYZ, enhanced its enzymatic activity, and prolonged its membrane retention. Mechanistically, corona-bound LYZ engaged Toll-like receptor 4 and activated a PGRN-LXR\u03b1 signaling axis, thereby increasing lysosomal acidification-dependent efferocytosis, promoting M2 macrophage polarization, and reducing CD8+ T-cell infiltration.

This effect is in part caused by a decline in mitochondrial function as well as by a reduction in lysosomal acidification. Because both mitochondria and lysosomes can alter one another's function, it remains unclear which initiating dysfunction sets off the detrimental cascade of LT, ultimately leading to \u03b2-cell failure. Here, we investigated the effects of restoring lysosomal acidity on mitochondrial function under LT. Our results show that LT induces a dose-dependent lysosomal alkalization accompanied by an increase in mitochondrial mass. This increase is due to a reduction in mitochondrial turnover as analyzed by MitoTimer, a fluorescent protein for which the emission is regulated by mitochondrial clearance rate. Mitochondrial oxygen consumption rate, citrate synthase activity, and ATP content are all reduced by LT. Restoration of lysosomal acidity using lysosome-targeted nanoparticles is accompanied by stimulation of mitochondrial turnover as revealed by mitophagy measurements and the recovery of mitochondrial mass. Remarkably, re-acidification restores citrate synthase activity and ATP content in an insulin secreting \u03b2-cell line (INS-1). Furthermore, nanoparticle-mediated lysosomal reacidification rescues mitochondrial maximal respiratory capacity in both INS-1 cells and primary mouse islets. Therefore, our results indicate that mitochondrial dysfunction is downstream of lysosomal alkalization under lipotoxic conditions and that recovery of lysosomal acidity is sufficient to restore the bioenergetic defects.-Assali, E.

This effect is in part caused by a decline in mitochondrial function as well as by a reduction in lysosomal acidification. Because both mitochondria and lysosomes can alter one another's function, it remains unclear which initiating dysfunction sets off the detrimental cascade of LT, ultimately leading to \u03b2-cell failure. Here, we investigated the effects of restoring lysosomal acidity on mitochondrial function under LT. Our results show that LT induces a dose-dependent lysosomal alkalization accompanied by an increase in mitochondrial mass. This increase is due to a reduction in mitochondrial turnover as analyzed by MitoTimer, a fluorescent protein for which the emission is regulated by mitochondrial clearance rate. Mitochondrial oxygen consumption rate, citrate synthase activity, and ATP content are all reduced by LT. Restoration of lysosomal acidity using lysosome-targeted nanoparticles is accompanied by stimulation of mitochondrial turnover as revealed by mitophagy measurements and the recovery of mitochondrial mass. Remarkably, re-acidification restores citrate synthase activity and ATP content in an insulin secreting \u03b2-cell line (INS-1). Furthermore, nanoparticle-mediated lysosomal reacidification rescues mitochondrial maximal respiratory capacity in both INS-1 cells and primary mouse islets. Therefore, our results indicate that mitochondrial dysfunction is downstream of lysosomal alkalization under lipotoxic conditions and that recovery of lysosomal acidity is sufficient to restore the bioenergetic defects.-Assali, E.

The pathophysiological consequences of GBA1 mutations on dopaminergic neuronal function, especially their impact on lysosomal function, mitophagy, and mitochondrial bioenergetics, remain unclear. Fibroblasts and dopaminergic neurons generated from induced pluripotent stem cells (iPSCs) derived from patients with\u00a0GBA1-PD were used in the study. Live-cell imaging was performed to measure lysosomal acidification, protease activity, mitochondrial membrane potential, and mitophagy. Mitochondrial morphology and autophagic vesicles were examined using transmission electron microscopy. Oxygen consumption rate was measured by Seahorse assay. V-ATPase assembly was quantified using fluorescence lifetime imaging with F\u00f6rster resonance energy transfer (FLIM-FRET), and pharmacological interventions included rapamycin and acidic nanoparticles. GCase activity, lysosomal acidification, protease activity, mitophagy and mitochondrial bioenergetic function were all impaired in GBA1 mutant dopaminergic neurons. Mitochondria were fragmented, with reduced membrane potential and oxygen consumption. Mechanistic target of rapamycin complex 1 (MTORC1) was constitutively phosphorylated and FLIM-FRET measurements confirmed impairment of lysosomal V-ATPase assembly, which was reversed by rapamycin treatment. Rapamycin and lysosome-targeting acidic nanoparticles rescued lysosomal pH and restored mitophagy, mitochondrial membrane potential and mitochondrial oxidative phosphorylation complex level in the GBA1 mutant dopaminergic neurons. We revealed a novel mechanistic link between GBA1 mutations and mitochondrial dysfunction, as the disruption of V-ATPase assembly driven by MTORC1 activation impairs lysosomal acidification. This causes impairment of mitophagy, leading to mitochondrial dysfunction, undermining dopaminergic cell function and fate. Pharmacological intervention with rapamycin or acidic nanoparticles restores lysosomal pH and rescue mitochondrial function, representing a novel therapeutic approach for\u00a0GBA1-PD ."

This study aimed to investigate whether NPs exposure accelerates osteoarthritis progression in osteoarthritic mice, to elucidate the underlying molecular mechanisms, and to evaluate the therapeutic potential of quercetin. OA was induced in C57BL/6 mice via destabilization of the medial meniscus (DMM), with or without exposure to 20-nm polystyrene NPs (0.5\u00a0mg/mL in drinking water). For therapeutic intervention, quercetin (25 or 50\u00a0mg/kg) or indomethacin (3\u00a0mg/kg) was administered daily. Cartilage destruction was assessed by histology using the Osteoarthritis Research Society International (OARSI) scoring system, immunohistochemistry, and X-ray. In vitro, primary murine chondrocytes were treated with NPs and/or quercetin. Mechanisms were investigated using transmission electron microscopy, immunofluorescence, Western blot, organelle staining, and siRNA knockdown. NPs exposure significantly accelerated cartilage degradation and OA progression in DMM mice. Internalized NPs accumulated in chondrocyte lysosomes, inducing lysosomal membrane permeabilization (LMP), cathepsin B release, and subsequent NLRP3 inflammasome activation, leading to pyroptosis (evidenced by cleavage of gasdermin D N-terminal, GSDMD-N) and extracellular matrix loss. Quercetin restored lysosomal integrity, inhibited the LMP-NLRP3-pyroptosis axis in chondrocytes, and markedly attenuated NPs-aggravated cartilage destruction in vivo. This study identifies nanoplastics as novel environmental risk factors that act as pathological amplifiers in the context of osteoarthritis by inducing lysosomal destabilization-mediated pyroptosis in chondrocytes. Quercetin alleviates this pathological cascade by stabilizing lysosomes, highlighting its potential as a therapeutic agent against nanoplastics-exacerbated OA."

Recent findings suggest that abnormal aggregation of pathogenic proteins within the nervous system may contribute to the neurotoxicity induced by nanoplastics, yet the molecular mechanisms regulating this pathological cascade remain unclear. Here, we used immature mice as an experimental model to represent infants and young children who are at higher risk of nanoplastics exposure, to elucidate the molecular mechanisms underlying neurotoxicity induced by exposure to polystyrene nanoplastics (PS-NPs) during early life. The results showed that environmentally relevant doses of PS-NPs penetrated the brains of immature mice and induced behavioral and emotional disorders. Proteomic analysis identified the mTOR signaling pathway as a candidate pathway responding to PS-NPs exposure in the immature mouse brain. Rapamycin intervention and quantitative validation further demonstrated that PS-NPs exposure upregulated mTOR signaling, thereby leading to lysosomal dysfunction and a blockade of autophagic flux, which in turn disrupted proteostasis and ultimately caused neurotoxicity. Furthermore, treatment with sodium 4-phenylbutyrate (4-PBA) confirmed that proteostasis imbalance, characterized by activation of the unfolded protein response, was a direct driver of this neurotoxicity. Notably, both rapamycin and 4-PBA treatments alleviated neurotoxicity resulting from PS-NPs exposure by restoring proteostasis. Together, these findings highlight dysregulation of the autophagy-lysosome pathway mediated by mTOR as a central mechanism of PS-NPs-induced neurotoxicity in immature mice and suggest lysosomal regulation for proteostasis remodeling as a prospective therapeutic strategy against neurological hazards related to nanoplastics."

MNPs can also adsorb other contaminants present in aquatic environments, and there is limited information on exposure scenarios involving MNP and pesticide mixtures. Ultraviolet (UV) radiation and chemical oxidation of MNPs can affect the sorption properties of MNPs and chemicals, thus altering the exposure and effects on fish. Our study investigated the toxicity and bioaccumulation of a lindane and dichlorodiphenyldichloroethylene (DDE) mixture adsorbed onto pristine and weathered polyethylene (PE) MNPs. Three different PE MNP types were used: microplastics (2-10 \u03bcm), oxidized microplastics (10-15 \u03bcm), and a MNP mixture (0.2-9.9 \u03bcm), and additionally each type was UV-aged for comparisons. RTgutGC cells, derived from rainbow trout (Oncorhynchus mykiss) intestine, were used to evaluate the role of the particle type on pesticides bioaccumulation and toxicity. Results showed that UV aging did not affect the agglomeration in solution but decreased the MNP's capacity to adsorb the pesticides (i.e., non-aged adsorbed 35% and 69% and UV-aged adsorbed 9.7% and 63% of lindane and DDE, respectively) likely due to a shift in MNPs hydrophobicity and consequently reduced the cytotoxicity of the pesticide MNPs mixture. Nanoplastics induced approximately 20% more lysosomal damage than microplastics, suggesting a distinct toxicity mechanism. Fluorescently labeled MNPs accumulated in intestinal cells which confirmed the internalization. Finally, bioaccumulation of DDE decreased approximately 2 to 8-fold in cells coexposed with all particle types, although lindane was not detected in the cells. Overall, our study indicated that MP and NPs reduce bioavailability of pesticides, but UV aging and particle fragmentation to nano size increased their bioaccumulation and toxicity in fish intestinal cells."

Here, we integrate the proton pump inhibitor pantoprazole (PTZ) with manganese ferrite nanoparticles (MFNs) within an acidity-responsive polymer for enhanced ferroptosis and cGAS-STING activation mediated immunotherapy. This assembly (PTZ/MFNAs) facilitates tumor accumulation through the enhanced permeability and retention effect while initially restricting the release of metal ions. Upon reaching the tumor site, PTZ release increases intracellular acidity, which further triggers assembly disintegration, accelerates the release of iron and manganese ions, and neutralizes the extracellular microenvironment to alleviate immunosuppression. The released manganese ions synergistically collaborate with iron ions to amplify reactive oxygen species (ROS) generation for ferroptosis while activating the cyclic guanosine monophosphate-adenosine monophosphate synthase-stimulator of interferon genes (cGAS-STING) pathway, stimulating innate immunity. This potentiation of innate immunity, coupled with the reversal of TME immunosuppression, collectively and effectively inhibits tumor growth and metastasis. Therefore, the PTZ/MFNAs co-delivery system represents a promising pH-modulation strategy to enhance iron/manganese ions-mediated ferroptosis and cGAS-STING activation-induced immunotherapy."

Mesenchymal stem cell-derived nanovesicle-poly(lactic-coglycolic acid) nanoparticles (MSC-PLGA-NPs) were prepared via sonication-loading. Blood-brain barrier (BBB) penetration was evaluated using in vitro transwell models and in vivo mouse models. Lysosomal function, autophagy, pathological protein clearance, and anti-inflammatory effects were assessed using various cellular and molecular biology techniques. MSC-PLGA-NPs demonstrated 2.3-fold higher BBB penetration efficiency compared to PLGA alone. In a chloroquine(CQ)-induced lysosomal injury model and mice model, they effectively restored lysosomal pH, enhanced autophagy (reducing LC3-II/I ratio by 0.4-fold and p62 expression by 52%), cleared amyloid precursor protein (APP) and phosphorylated tau (p-tau) proteins, and inhibited IL-6 and TNF-\u03b1 without hepatorenal toxicity. These results demonstrate that MSC-PLGA-NPs, a novel multifunctional nanoparticle platform, synergistically integrates the BBB penetration capability of MSC-NVs and the lysosomal acidification function of PLGA. The synergistic combination represents a pioneering \"delivery-repair-clearance\" integrated strategy for AD therapy.

This study investigated the effects of polystyrene (PS) NPs on steatosis and fatty liver disease. PS-NP oral administration, in conjunction with a high-fat diet (HFD), synergistically exacerbated the symptoms of steatosis in mice, leading to increased alanine transaminase, aspartate aminotransferase, and cholesterol levels; no effects were observed with PS-NPs on a normal chow diet. Transcriptome analysis unveiled that PS-NPs interfered with actin organization, cell-cell adhesion, PPAR signaling, and lipid metabolism. In HepaRG cells, PS-NPs rapidly entered by inducing actin rearrangement, resulting in the formation of numerous small cytoplasmic vesicles. This treatment led to an augmented number of acidic organelles, leading to development and buildup of large vacuoles, indicative of enlarged pre-lysosomal and lysosomal compartments. PS-NP exposure hampered p62 degradation, leading to LC3B accumulation and decreased cathepsin B and D activity. Additionally, PS-NP exposure resulted in accumulation of lipid droplets and elevated expression of lipogenesis-, transport-, and storage-related genes. These findings suggest that excessive endocytosis driven by PS-NPs worsens MASLD in HFD through accumulation of lysosomes and large vacuoles with reduced cathepsin activity."

Environmental toxins are considered the main etiological factor. The increasing use of polystyrene nanoparticles (PS-NPs) has raised concerns about their potential neurotoxic effects in PD. This study aimed to investigate the impact of PS-NPs on the onset and progression of PD and the underlying mechanisms. The breach of the blood-brain barrier (BBB) by PS-NPs was assessed using bioluminescence imaging, fluorescence observation, Pyrolysis-Gas Chromatography-Mass Spectrometry (Py-GCMs), transmission electron microscope (TEM), and Evans blue staining. To evaluate the potential promotion of PD by PS-NPs, a 30-day repeated oral administration study was conducted in vivo, during which behavioral changes and alterations in dopaminergic neurons in the substantia nigra were assessed. In vitro cytotoxicity assays were performed following PS-NPs intervention. Molecular biology techniques, including Western blotting and immunofluorescence, were employed to analyze proteins related to pyroptosis and autophagy-lysosomal pathway in both in vivo and in vitro settings. Additionally, proteomic sequencing was utilized to identify the upstream regulator of the autophagy-lysosomal pathway (ALP), and the effects of modulating this target protein on the ALP-pyroptosis pathway were analyzed. Bioluminescence imaging and Py-GCMs confirmed that PS-NPs entered the brain within 1.5\u00a0h. Evans blue staining and TEM showed PS-NPs damaged the BBB. The 30-day oral toxicity revealed that PS-NPs exacerbated behavioral abnormalities and caused dopaminergic neuron loss. Western blotting and immunofluorescence indicated that PS-NPs induced pyroptosis, disrupted autophagic flux, and lowered protein levels involved in autophagosome-lysosome fusion, both in vivo and in vitro. Furthermore, PS-NPs activated the mechanistic target of rapamycin (mTOR) and inhibited the nuclear translocation of Transcription Factor EB (TFEB). Proteomic sequencing identified a deficit of Tuberous Sclerosis Complex (TSC) 2 protein within the mTOR pathway. Immuno-coprecipitation and Coomassie Blue Fast Staining revealed that PS-NPs bound to TSC2 protein, causing disassembly of TSC1-TSC2 complex. These findings underscore how PS-NPs accelerated PD onset and progression by disrupting autophagosome-lysosome fusion through TSC2-mTOR-TFEB axis, which triggered protein degradation disorders and pyroptosis in dopaminergic neurons. The molecular mechanisms could inform environmental safety regulations concerning nanoplastics and inspire therapeutic strategies for PD."

Its silk glands are responsible for the synthesis and secretion of silk proteins. The naked pupa (Nd), a fibroin heavy chain mutant strain of silkworm, was found to exhibit severe atrophy, degeneration of the posterior silk gland (PSG), and abnormal secretion of fibroin proteins, thereby producing little or no silk. Here, we found that the autophagic marker Atg8-PE was upregulated through the target of rapamycin complex 1 signaling pathway in Nd. However, as autophagy substrates, SQSTM1/p62 and ubiquitinated protein levels increased in Nd. Furthermore, treatment with BafA1 showed no effect on the protein levels of SQSTM1/p62, indicating impaired autophagic flux in Nd. Abnormal acidification of lysosomes was further detected, which resulted in a decreased proportion of matured CtsL1 (cathepsin L1). Thus, the substrate in autolysosomes cannot be degraded within a rapid time frame, resulting in the accumulation of protein aggregates, which cause atrophy and degeneration of the PSG. We also found that acidic nanoparticles rescued lysosomal acidification and relieved the degenerative changes of Nd-PSG. The findings of this study suggest that the Nd mutant silkworm can be used as an animal model for studying protein aggregation diseases.Abbreviations: AD: Alzheimer disease; aNP: acidic nanoparticle; APP: amyloid beta precursor protein; Atg8: autophagy related 8; BACE1: beta-secretase 1; BafA1: bafilomycin A1; CtsL1: cathepsin L1; CRY: crystallin; ER: endoplasmic reticulum; FibH: fibroin heavy chain; FibL: fibroin light chain; FUS: FUS RNA binding protein; HD: Huntington disease; HRP: horseradish peroxidase; Nd: naked pupa; OSBPL2: oxysterol binding protein like 2; PD: Parkinson disease; PE: phosphatidylethanolamine; p-EIF4EBP: phosphorylated eukaryotic initiation factor 4E binding protein; PROM1: prominin 1; p-RPS6KB: phosphorylated ribosomal protein S6 kinase B; PSEN: presenilin; PSG: posterior silk gland; SDS-PAGE: sodium dodecyl sulfate-polyacrylamide gel electrophoresis; SEM: standard error of the mean; SOD1: superoxide dismutase 1; SQSTM1/p62: sequestosome 1; TARDBP: TAR DNA binding protein; TORC1: target of rapamycin complex 1; UBQLN2: ubiquilin 2; V-ATPase: vacuolar-type ATPase."

This study investigated the impact of polystyrene NPs on Eisenia fetida (Savigny, 1826) immune cells, focusing on oxidative stress, immune responses, apoptosis, and necrosis. Results showed that 100 nm NPs were internalized into the cells, causing cytotoxicity. NPs were observed to inhibit cell viability by increasing reactive oxygen species, decreasing the levels of antioxidants (e.g., superoxide dismutase, catalase, and glutathione), and inducing lipid peroxidation and DNA oxidation. Additionally, assays on neutral red retention time, lysozyme activity, and Ca2\u207a levels demonstrated that NPs resulted in a loss of lysosomal membrane stability and a reduction in immune resistance. The depolarization of the mitochondrial membrane potential and the results of the apoptosis assays confirmed that the NPs induced the onset of early apoptosis. The difficulty of the NP in causing cell death by disrupting the plasma membrane was demonstrated by the results of the lactate dehydrogenase release assays in relation to cell necrosis.

Devising strategies to rescue this macrophage lysosomal dysfunction is a novel therapeutic measure. Nanoparticles have emerged as an effective platform to both target specific tissues and serve as drug delivery vehicles. In most cases, administered nanoparticles are taken up non-selectively by the mononuclear phagocyte system including monocytes/macrophages leading to the undesirable degradation of cargo in lysosomes. We took advantage of this default route to target macrophage lysosomes to rectify their acidity in disease states such as atherosclerosis. Herein, we develop and test two commonly used acidic nanoparticles, poly-lactide-co-glycolic acid (PLGA) and polylactic acid (PLA), both in vitro and in vivo. Our results in cultured macrophages indicate that the PLGA-based nanoparticles are the most effective at trafficking to and enhancing acidification of lysosomes. PLGA nanoparticles also provide functional benefits including enhanced lysosomal degradation, promotion of macroautophagy/autophagy and protein aggregate removal, and reduced apoptosis and inflammasome activation. We demonstrate the utility of this system in vivo, showing nanoparticle accumulation in, and lysosomal acidification of, macrophages in atherosclerotic plaques. Long-term administration of PLGA nanoparticles results in significant reductions in surrogates of plaque complexity with reduced apoptosis, necrotic core formation, and cytotoxic protein aggregates and increased fibrous cap formation.

We investigate whether restoration of lysosomal function in NAFLD recovers autophagic flux, mitochondrial function, and insulin sensitivity. Here, we report the synthesis of novel biodegradable acid-activated acidifying nanoparticles (acNPs) as a lysosome targeting treatment to restore lysosomal acidity and autophagy. The acNPs, composed of fluorinated polyesters, remain inactive at plasma pH, and only become activated in lysosomes after endocytosis. Specifically, they degrade at pH of ~6 characteristic of dysfunctional lysosomes, to further acidify and enhance the function of lysosomes. In established in vivo high fat diet mouse models of NAFLD, re-acidification of lysosomes via acNP treatment restores autophagy and mitochondria function to lean, healthy levels. This restoration, concurrent with reversal of fasting hyperglycemia and hepatic steatosis, indicates the potential use of acNPs as a first-in-kind therapeutic for NAFLD."

High levels of free fatty acids in the liver impair hepatic lysosomal acidification and reduce autophagic flux. We investigate whether restoration of lysosomal function in NAFLD recovers autophagic flux, mitochondrial function, and insulin sensitivity. Here, we report the synthesis of novel biodegradable acid-activated acidifying nanoparticles (acNPs) as a lysosome targeting treatment to restore lysosomal acidity and autophagy. The acNPs, composed of fluorinated polyesters, remain inactive at plasma pH, and only become activated in lysosomes after endocytosis. Specifically, they degrade at pH of ~6 characteristic of dysfunctional lysosomes, to further acidify and enhance the function of lysosomes. In established in vivo high fat diet mouse models of NAFLD, re-acidification of lysosomes via acNP treatment restores autophagy and mitochondria function to lean, healthy levels. This restoration, concurrent with reversal of fasting hyperglycemia and hepatic steatosis, indicates the potential use of acNPs as a first-in-kind therapeutic for NAFLD."

Tris(2-butoxyethyl) phosphate (TBOEP) is a representative organophosphate ester that is widely detected in environmental matrices and human tissues, yet whether chronic exposure to environmentally relevant concentrations of TBOEP drives progressive neurodegenerative pathology remains unclear. Here, using Caenorhabditis elegans as a model organism, we performed a 20-day, time-resolved life-cycle exposure to environmentally relevant concentrations of TBOEP (50-5000\u202fng/L) to systematically assess chronic neurotoxicity. TBOEP exposure induced progressive, age-dependent neurodegenerative phenotypes. Early effects were characterized by selective impairment of locomotor performance starting at 50\u202fng/L, followed by broader systemic toxicity, including growth retardation, feeding deficits, and accelerated aging. Consistent with a Parkinson's disease-like trajectory, hallmark pathological features progressively worsened with exposure duration, including dopamine-dependent functional impairment, while \u03b1-synuclein aggregation and dopaminergic neuronal impairment were mainly observed at concentrations \u2265\u202f500\u202fng/L. Mechanistically, time-resolved transcriptomics identified the lysosomal pathway as a central target of TBOEP. Functional assays further confirmed that TBOEP significantly impaired lysosomal acidification. Pharmacological validation with the lysosomal chaperone ambroxol showed that improving lysosomal function mitigated TBOEP-induced neurotoxicity, supporting lysosomal dysfunction as a primary contributor to the observed pathology. Collectively, our findings identify TBOEP as a potential environmental risk factor for neurodegeneration, providing important insights that could inform further studies assessing the environmental health risks of organophosphate esters."

Although inhaled NPs rapidly acquire a protein corona that shapes their bioactivity, the consequences of this process in cancer-susceptible lungs remain unclear. Here, we investigated whether NPs form a disease-specific pathogenic protein corona in lung adenocarcinoma that rewires immune signaling and accelerates tumor progression. Polyethylene terephthalate (PET) NPs were generated by mechanical fragmentation and extensively characterized. In tumor-bearing mice, inhaled PET NPs accelerated tumor growth relative to controls. Proteomic analysis of PET NPs incubated with bronchoalveolar lavage fluid from patients with lung adenocarcinoma identified lysozyme (LYZ) as a selectively enriched corona component associated with tumor stage and metastasis. Corona formation induced conformational remodeling of LYZ, enhanced its enzymatic activity, and prolonged its membrane retention. Mechanistically, corona-bound LYZ engaged Toll-like receptor 4 and activated a PGRN-LXR\u03b1 signaling axis, thereby increasing lysosomal acidification-dependent efferocytosis, promoting M2 macrophage polarization, and reducing CD8+ T-cell infiltration. In vivo, AAV9-mediated knockdown of LYZ or PGRN attenuated PET NP-induced efferocytosis, reversed immunosuppressive reprogramming, restored CD8+ T-cell infiltration, and suppressed tumor growth, demonstrating the functional requirement for this corona pathway. These findings establish disease-derived PET NP coronas as active nano-bio interfaces that connect environmental PET NP exposure with efferocytosis-driven immune evasion in lung adenocarcinoma. This work provides a mechanistic link between airborne NPs and tumor progression in susceptible hosts and highlights corona-mediated signaling as a potential therapeutic target and environmental health concern."

This effect is in part caused by a decline in mitochondrial function as well as by a reduction in lysosomal acidification. Because both mitochondria and lysosomes can alter one another's function, it remains unclear which initiating dysfunction sets off the detrimental cascade of LT, ultimately leading to \u03b2-cell failure. Here, we investigated the effects of restoring lysosomal acidity on mitochondrial function under LT. Our results show that LT induces a dose-dependent lysosomal alkalization accompanied by an increase in mitochondrial mass. This increase is due to a reduction in mitochondrial turnover as analyzed by MitoTimer, a fluorescent protein for which the emission is regulated by mitochondrial clearance rate. Mitochondrial oxygen consumption rate, citrate synthase activity, and ATP content are all reduced by LT. Restoration of lysosomal acidity using lysosome-targeted nanoparticles is accompanied by stimulation of mitochondrial turnover as revealed by mitophagy measurements and the recovery of mitochondrial mass. Remarkably, re-acidification restores citrate synthase activity and ATP content in an insulin secreting \u03b2-cell line (INS-1). Furthermore, nanoparticle-mediated lysosomal reacidification rescues mitochondrial maximal respiratory capacity in both INS-1 cells and primary mouse islets. Therefore, our results indicate that mitochondrial dysfunction is downstream of lysosomal alkalization under lipotoxic conditions and that recovery of lysosomal acidity is sufficient to restore the bioenergetic defects.-Assali, E.

The pathophysiological consequences of GBA1 mutations on dopaminergic neuronal function, especially their impact on lysosomal function, mitophagy, and mitochondrial bioenergetics, remain unclear. Fibroblasts and dopaminergic neurons generated from induced pluripotent stem cells (iPSCs) derived from patients with\u00a0GBA1-PD were used in the study. Live-cell imaging was performed to measure lysosomal acidification, protease activity, mitochondrial membrane potential, and mitophagy. Mitochondrial morphology and autophagic vesicles were examined using transmission electron microscopy. Oxygen consumption rate was measured by Seahorse assay. V-ATPase assembly was quantified using fluorescence lifetime imaging with F\u00f6rster resonance energy transfer (FLIM-FRET), and pharmacological interventions included rapamycin and acidic nanoparticles. GCase activity, lysosomal acidification, protease activity, mitophagy and mitochondrial bioenergetic function were all impaired in GBA1 mutant dopaminergic neurons. Mitochondria were fragmented, with reduced membrane potential and oxygen consumption. Mechanistic target of rapamycin complex 1 (MTORC1) was constitutively phosphorylated and FLIM-FRET measurements confirmed impairment of lysosomal V-ATPase assembly, which was reversed by rapamycin treatment. Rapamycin and lysosome-targeting acidic nanoparticles rescued lysosomal pH and restored mitophagy, mitochondrial membrane potential and mitochondrial oxidative phosphorylation complex level in the GBA1 mutant dopaminergic neurons. We revealed a novel mechanistic link between GBA1 mutations and mitochondrial dysfunction, as the disruption of V-ATPase assembly driven by MTORC1 activation impairs lysosomal acidification. This causes impairment of mitophagy, leading to mitochondrial dysfunction, undermining dopaminergic cell function and fate. Pharmacological intervention with rapamycin or acidic nanoparticles restores lysosomal pH and rescue mitochondrial function, representing a novel therapeutic approach for\u00a0GBA1-PD ."

MNPs can also adsorb other contaminants present in aquatic environments, and there is limited information on exposure scenarios involving MNP and pesticide mixtures. Ultraviolet (UV) radiation and chemical oxidation of MNPs can affect the sorption properties of MNPs and chemicals, thus altering the exposure and effects on fish. Our study investigated the toxicity and bioaccumulation of a lindane and dichlorodiphenyldichloroethylene (DDE) mixture adsorbed onto pristine and weathered polyethylene (PE) MNPs. Three different PE MNP types were used: microplastics (2-10 \u03bcm), oxidized microplastics (10-15 \u03bcm), and a MNP mixture (0.2-9.9 \u03bcm), and additionally each type was UV-aged for comparisons. RTgutGC cells, derived from rainbow trout (Oncorhynchus mykiss) intestine, were used to evaluate the role of the particle type on pesticides bioaccumulation and toxicity. Results showed that UV aging did not affect the agglomeration in solution but decreased the MNP's capacity to adsorb the pesticides (i.e., non-aged adsorbed 35% and 69% and UV-aged adsorbed 9.7% and 63% of lindane and DDE, respectively) likely due to a shift in MNPs hydrophobicity and consequently reduced the cytotoxicity of the pesticide MNPs mixture. Nanoplastics induced approximately 20% more lysosomal damage than microplastics, suggesting a distinct toxicity mechanism. Fluorescently labeled MNPs accumulated in intestinal cells which confirmed the internalization. Finally, bioaccumulation of DDE decreased approximately 2 to 8-fold in cells coexposed with all particle types, although lindane was not detected in the cells. Overall, our study indicated that MP and NPs reduce bioavailability of pesticides, but UV aging and particle fragmentation to nano size increased their bioaccumulation and toxicity in fish intestinal cells."

Mesenchymal stem cell-derived nanovesicle-poly(lactic-coglycolic acid) nanoparticles (MSC-PLGA-NPs) were prepared via sonication-loading. Blood-brain barrier (BBB) penetration was evaluated using in vitro transwell models and in vivo mouse models. Lysosomal function, autophagy, pathological protein clearance, and anti-inflammatory effects were assessed using various cellular and molecular biology techniques. MSC-PLGA-NPs demonstrated 2.3-fold higher BBB penetration efficiency compared to PLGA alone. In a chloroquine(CQ)-induced lysosomal injury model and mice model, they effectively restored lysosomal pH, enhanced autophagy (reducing LC3-II/I ratio by 0.4-fold and p62 expression by 52%), cleared amyloid precursor protein (APP) and phosphorylated tau (p-tau) proteins, and inhibited IL-6 and TNF-\u03b1 without hepatorenal toxicity. These results demonstrate that MSC-PLGA-NPs, a novel multifunctional nanoparticle platform, synergistically integrates the BBB penetration capability of MSC-NVs and the lysosomal acidification function of PLGA. The synergistic combination represents a pioneering \"delivery-repair-clearance\" integrated strategy for AD therapy. Offering significant advantages over single-component approaches, MSC-PLGA-NPs provide a promising preclinical candidate and new insight into lysosome-targeted nanomedicines for neurodegenerative diseases."

This study investigated the effects of polystyrene (PS) NPs on steatosis and fatty liver disease. PS-NP oral administration, in conjunction with a high-fat diet (HFD), synergistically exacerbated the symptoms of steatosis in mice, leading to increased alanine transaminase, aspartate aminotransferase, and cholesterol levels; no effects were observed with PS-NPs on a normal chow diet. Transcriptome analysis unveiled that PS-NPs interfered with actin organization, cell-cell adhesion, PPAR signaling, and lipid metabolism. In HepaRG cells, PS-NPs rapidly entered by inducing actin rearrangement, resulting in the formation of numerous small cytoplasmic vesicles. This treatment led to an augmented number of acidic organelles, leading to development and buildup of large vacuoles, indicative of enlarged pre-lysosomal and lysosomal compartments. PS-NP exposure hampered p62 degradation, leading to LC3B accumulation and decreased cathepsin B and D activity. Additionally, PS-NP exposure resulted in accumulation of lipid droplets and elevated expression of lipogenesis-, transport-, and storage-related genes. These findings suggest that excessive endocytosis driven by PS-NPs worsens MASLD in HFD through accumulation of lysosomes and large vacuoles with reduced cathepsin activity."

Its silk glands are responsible for the synthesis and secretion of silk proteins. The naked pupa (Nd), a fibroin heavy chain mutant strain of silkworm, was found to exhibit severe atrophy, degeneration of the posterior silk gland (PSG), and abnormal secretion of fibroin proteins, thereby producing little or no silk. Here, we found that the autophagic marker Atg8-PE was upregulated through the target of rapamycin complex 1 signaling pathway in Nd. However, as autophagy substrates, SQSTM1/p62 and ubiquitinated protein levels increased in Nd. Furthermore, treatment with BafA1 showed no effect on the protein levels of SQSTM1/p62, indicating impaired autophagic flux in Nd. Abnormal acidification of lysosomes was further detected, which resulted in a decreased proportion of matured CtsL1 (cathepsin L1). Thus, the substrate in autolysosomes cannot be degraded within a rapid time frame, resulting in the accumulation of protein aggregates, which cause atrophy and degeneration of the PSG. We also found that acidic nanoparticles rescued lysosomal acidification and relieved the degenerative changes of Nd-PSG. The findings of this study suggest that the Nd mutant silkworm can be used as an animal model for studying protein aggregation diseases.Abbreviations: AD: Alzheimer disease; aNP: acidic nanoparticle; APP: amyloid beta precursor protein; Atg8: autophagy related 8; BACE1: beta-secretase 1; BafA1: bafilomycin A1; CtsL1: cathepsin L1; CRY: crystallin; ER: endoplasmic reticulum; FibH: fibroin heavy chain; FibL: fibroin light chain; FUS: FUS RNA binding protein; HD: Huntington disease; HRP: horseradish peroxidase; Nd: naked pupa; OSBPL2: oxysterol binding protein like 2; PD: Parkinson disease; PE: phosphatidylethanolamine; p-EIF4EBP: phosphorylated eukaryotic initiation factor 4E binding protein; PROM1: prominin 1; p-RPS6KB: phosphorylated ribosomal protein S6 kinase B; PSEN: presenilin; PSG: posterior silk gland; SDS-PAGE: sodium dodecyl sulfate-polyacrylamide gel electrophoresis; SEM: standard error of the mean; SOD1: superoxide dismutase 1; SQSTM1/p62: sequestosome 1; TARDBP: TAR DNA binding protein; TORC1: target of rapamycin complex 1; UBQLN2: ubiquilin 2; V-ATPase: vacuolar-type ATPase."

Nevertheless, their toxicity mechanisms in soil invertebrates remain unclear. This study investigated the impact of polystyrene NPs on Eisenia fetida (Savigny, 1826) immune cells, focusing on oxidative stress, immune responses, apoptosis, and necrosis. Results showed that 100 nm NPs were internalized into the cells, causing cytotoxicity. NPs were observed to inhibit cell viability by increasing reactive oxygen species, decreasing the levels of antioxidants (e.g., superoxide dismutase, catalase, and glutathione), and inducing lipid peroxidation and DNA oxidation. Additionally, assays on neutral red retention time, lysozyme activity, and Ca2\u207a levels demonstrated that NPs resulted in a loss of lysosomal membrane stability and a reduction in immune resistance. The depolarization of the mitochondrial membrane potential and the results of the apoptosis assays confirmed that the NPs induced the onset of early apoptosis.

Consequently, the toxicology of such particles has emerged as a pivotal research interests in recent years. In this study, NP was synthesized successfully with an average particle size of 100\u00a0nm using a emulsion polymerization method as model particles. Following co-incubation of IEC-6 cells with NP for 24-168\u00a0h, a notable inhibition of cell viability and proliferation was observed. The significant activation of autophagy and a concomitant blockage of autophagic flux in IEC-6 cells after 24-72\u00a0h of co-incubation with NP were unveiled by transmission electron microscopy, western blotting, and double-fluorescent autophagy analysis. A significant increase in the number of lysosomes and an increase in the expression of hydrolase CTSB were detected, indicating dysregulation of lysosomal function. The subsequent transcriptomic and metabolomics analyses, coupled with the observation of activated lysosomes and the RIPK1-RIPK3-MLKL/PYGL pathway, led us to posit that the blockade of autophagy and lysosomal dysfunction, culminating in lysosomal membrane permeabilization (LMP) induced necroptosis, constitutes one of the mechanisms contributing to the cytotoxicity of NP.

This study evaluates the efficacy of thermostable ZnO NPs/AA nanocomposites in suppressing S.mutans acid production, disrupting its biofilm matrix, and strengthening enamel integrity, with an emphasis on its potential as a novel dental healthcare material. This study encompassed the synthesis of zinc oxide nanoparticles functionalized with Asiatic acid (ZnO NPs/AA) using a co-precipitation method. The physicochemical properties of ZnO NPs/AA were characterized using FE-SEM with EDS, XRD, FT-IR, and UV-DRS, confirming structural integrity and functional modifications.

The antibacterial activity, anti-biofilm efficacy of ZnO NPs/AA including, extracellular polymeric substance inhibition, and acidogenic activity modulation were evaluated through microdilution methods, biofilm biomass quantification assays, Congo red binding studies, and pH analysis. In ex-vivo studies, ZnO NPs/AA treated sectioned tooth enamel was exposed to S. mutans to evaluate its effects. The mechanical properties, including microhardness and surface morphology, were analyzed using Vickers microhardness testing and Atomic Force Microscopy (AFM). Additionally, the controlled release kinetics of Asiatic acid were analyzed under physiological (pH 7.4) and acidic (pH 5.0) conditions to elucidate its pH-responsive drug delivery potential. A precisely synthesized ZnO NPs/AA with a sheet-assembled flower-like structure was observed through SEM analysis, while its composition and functionalization were further confirmed by FTIR and UV-DRS. Thermal stability was validated through TGA and DSC analyses, establishing ZnO NPs/AA as a highly thermally stable material for biomedical applications. ZnO NPs/AA exhibited remarkable multi-functional properties, including potent antibacterial activity, leading to an 85.25 % reduction in S. mutans biofilm biomass and an 81 % inhibition of EPS production. pH modulation studies demonstrated effective neutralization of acidogenic activity, maintaining a near-neutral pH (7.01 at 48 h), significantly outperforming ZnO NPs and the untreated control. Enamel treated with ZnO NPs/AA following exposure to S.mutans showed a 72.6 % increase in microhardness and a 80.93 % reduction in surface roughness, highlighting its ability to combat S.mutans induced demineralization and acid formation, thereby preserving the enamel integrity.

This study investigates the toxicological effects of spherical PSMPs (<0.50\u202f\u00b5m) on Raw 264.7 murine macrophages, critical immune cells that actively internalize foreign materials. At exposure concentrations ranging from 50 to 500\u202f\u00b5g/mL, PSMPs were rapidly internalized within 2\u202fh, with accumulation increasing over time. Notably, high-dose exposure (500\u202f\u00b5g/mL) resulted in significant mitochondrial membrane damage, lysosomal dysfunction, elevated reactive oxygen species (ROS) levels, and lipid peroxidation. These cellular stress responses were accompanied by increased levels of LDH and SOD, as well as the induction of apoptosis and cellular senescence. The findings show that PSMPs disrupt mitochondrial function and contribute to senescence responses, ultimately compromising immune cell viability and function. This study provides new insight into the intracellular fate and toxicity of environmentally relevant PSMPs and emphasizes the need for urgent evaluation of plastic pollution's impact on human health."

However, whether NPs induce renal fibrosis remains contentious, and the reversibility of NPs-triggered nephrotoxicity has rarely been reported. This study investigated the role of lysosomes in renal fibrosis induced by low-level polystyrene (PS) NPs with particle sizes of 100 and 500 nm (PS100 and PS500) in mice using Masson staining, immunohistochemistry, Western blotting, fluorescence imaging, and other techniques. The results showed that PS100 induced more pronounced renal fibrosis than PS500. Mechanistically, PS NPs promoted autophagosome formation accompanied by the inhibition of autophagic degradation. Moreover, PS NPs impaired lysosomal degradation function, evidenced by reduced CTSB and CTSD protein levels. This impairment blocked autophagic flux, thereby inducing renal fibrosis, which was further confirmed by in vitro results. Notably, lysosomal exocytosis plays a crucial role in the clearance of NPs from mouse kidneys through activating Mcoln1 expression, which contributes to restoring autophagic flux and alleviating renal fibrosis during recovery. Collectively, our findings provide the first evidence that lysosomes serve dual functions in the persistence and reversibility of NPs-induced nephrotoxicity, which could be valuable for the intervention and mitigation of kidney damage resulting from environmental NPs exposure."

This study investigated the aggregation and deposition kinetics of six polystyrene NPs (PSNPs): NP50, NP100, NP500, A-NP50 and A-NP100 (amino-modified), and C-NP100 (carboxyl-modified), in artificial lysosomal fluid (ALF) and Gamble's solution (GMB). In ALF, PSNPs aggregated within 20\u202fmin to 132-1066\u202fnm, with rates ranking A-NP50\u202f>\u202fNP100\u202f>\u202fA-NP100\u202f>\u202fC-NP100\u202f>\u202fNP50\u202f>\u202fNP500. After 24\u202fh, most exceeded 5000\u202fnm, except NP500 (1473\u202fnm). In GMB, only positively charged A-NP50 aggregated substantially (> 5000\u202fnm), while negatively charged PSNPs remained stable. All PSNPs exhibited higher deposition rates in ALF than GMB. Higher particle concentrations promoted aggregation for all PSNPs in ALF, but only A-NP50 in GMB. Opposite pH effects on A-NP50 and NP50 were observed. Na2HPO4, NaHCO3, sodium pyruvate, and trisodium citrate promoted A-NP50 aggregation via electrostatic interactions and adsorption. BSA modulated aggregation in a concentration- and fluid-dependent manner: low levels (< 260\u202fmg/L) enhanced NP50 aggregation via charge screening, while higher levels stabilized it via steric hindrance. For A-NP50, BSA consistently reduced aggregation. These findings provide insights into NP transport and health risks in pulmonary environments."

In HAND, the persistence of white matter alterations despite suppressive antiretroviral (ARV) therapy suggests that ARVs may be directly contributing to these impairments. Here, we report that a frontline ARV, bictegravir (BIC), significantly attenuates remyelination following cuprizone-mediated demyelination, a model that recapitulates acute demyelination, but has no impact on already formed mature myelin. Mechanistic studies utilizing primary rat oligodendrocyte precursor cells (OPCs) revealed that treatment with BIC leads to significant decrease in mature oligodendrocytes accompanied by lysosomal deacidification and impairment of lysosomal degradative capacity with no alterations in lysosomal membrane permeability or total lysosome number. Activation of the endolysosomal cation channel TRPML1 prevents both lysosomal deacidification and impairment of oligodendrocyte differentiation by BIC. Lastly, we show that deacidification of lysosomes by compounds that raise lysosomal pH is sufficient to prevent maturation of oligodendrocytes. Overall, this study has uncovered a critical role for lysosomal acidification in modulating oligodendrocyte function and has implications for neurologic diseases characterized by lysosomal dysfunction and white matter abnormalities."

Loss of lysosome function impacts VSMC homeostasis and disease progression. Understanding the molecular mechanisms underlying lysosome dysfunction in these cells is, therefore, crucial. We identify cholesteryl hemiazelate (ChA), a stable oxidation end-product of cholesteryl-polyunsaturated fatty acid esters, as an inducer of lysosome malfunction in VSMCs. ChA-treated VSMCs acquire a foam-cell-like phenotype, characterized by enlarged lysosomes full of ChA and neutral lipids. The lysosomes are perinuclear and exhibit degradative capacity and cargo exit defects. Lysosome luminal pH is also altered. Even though the transcriptional response machinery and autophagy are not activated by ChA, the addition of recombinant lysosomal acid lipase (LAL) is able to rescue lysosome dysfunction. ChA significantly affects VSMC proliferation and migration, impacting atherosclerosis. In summary, this work shows that ChA is sufficient to induce lysosomal dysfunction in VSMCs, that, in ChA-treated VSMCs, neither lysosome biogenesis nor autophagy are triggered, and, finally, that recombinant LAL can be a therapeutic approach for lysosomal dysfunction."

Evidence confirms that nanoplastic-induced lysosomal dysfunction and alkalization are central features of cellular toxicity, and independent evidence confirms that lysosome-acidifying nanoparticles successfully restore lysosomal pH and degradative capacity in stressed models. While no study in the provided literature directly tests the cross-application of AcNPs for nanoplastic-induced damage, the mechanistic commonality of lysosomal alkalization suggests a potential for cross-platform adaptation.\n\n### [ABSTRACT & REWRITTEN CLAIM]\nLysosomal alkalization is a common pathological outcome of both neurodegenerative disease processes and environmental exposures, including nanoplastics. Experimental therapies utilizing pH-modulating nanomaterials have demonstrated success in restoring lysosomal acidity, enhancing autophagic flux, and preventing cell death. This evaluation synthesizes evidence regarding the structural and functional restoration of lysosomes to support the hypothesis that acidifying nanoplatforms can mitigate contaminant-induced lysosomal failure.\n\n### [INTRODUCTION & JUSTIFICATION]\nLysosomal homeostasis is essential for cellular quality control and degradative efficiency. Emerging research indicates that environmental stressors, such as nanoplastics and industrial toxins, specifically target the lysosomal apparatus, inducing alkalization, lysosomal membrane permeabilization, and autophagic blockades. \"These molecular alterations, together with lysosomal inhibition assays, functionally support lysosomal dysfunction as a key constraint on lipophagy.\" In parallel, engineered nanotechnologies have shown robust efficacy in reversing such deficits. \"These nanomaterials were developed to locally acidify impaired lysosomes and restore their degradative capacity.\" Furthermore, \"Restoring lysosomal acidity is important for maintaining enzymatic degradation, preventing protein aggregation, and reducing cellular waste accumulation in degenerating tissues.\" By integrating these findings, we observe that lysosome-acidifying agents function as a potential remedial node across multiple pathologies. \"Defective lysosomal acidification in astrocytes impairs their autophagic and phagocytic functions, resulting in the accumulation of cellular debris, excessive myelin and lipids, and toxic protein aggregates.\" Consequently, the adaptive utilization of AcNPs appears highly promising for reversing the loss of autophagic flux induced by environmental stressors.\n\n### [DISCUSSION: NOVEL & OVERLOOKED]\n* Lysosomal acidification strategies are effective across diverse pathological models, including proteinopathy, environmental toxicity, and metabolic disorders.\n* The V-ATPase is a shared primary target for both disease-associated lysosomal failure and contaminant-induced alkalization.\n* Nanoparticle surface modification (e.g., Cy3-labeling) is essential for monitoring the retention and longevity of pH-restoring agents within the acidic environment.\n* Lysosomal stress can trigger distinct pathways, such as non-canonical autophagy or the Conjugation of ATG8s to single membranes (CASM), as an adaptive response to toxin exposure.\n* The loss of lysosomal acidity is often directly linked to the initiation of necroptotic or apoptotic pathways, rendering pH restoration a cytoprotective necessity.\n* Some environmental toxins, like tributyltin, utilize the V-ATPase-ATG16L1 axis to modulate transcriptional programs like TFEB.\n* Cross-species evidence suggests that restoration of lysosomal function can mitigate inflammation and metabolic distress.\n\n### [EVIDENCE, METHODOLOGY & CITATIONS]\n1.

Evidence confirms that nanoplastics and other environmental contaminants frequently induce lysosomal dysfunction, including alkalization, blockade of autophagic flux, and cathepsin inhibition. The proposal that AcNPs could be repurposed to mitigate nanoplastic-induced toxicity is mechanistically plausible given the convergent pathways of lysosomal impairment, although direct experimental evidence of AcNP application to nanoplastic-induced lysosomal damage in vivo is currently limited.\n\n### [ABSTRACT & REWRITTEN CLAIM]\nLysosomal integrity is a critical requirement for maintaining cellular homeostasis, particularly in the clearance of protein aggregates and lipid metabolism. Environmental contaminants, such as polystyrene nanoplastics, frequently target the endolysosomal system, causing pH elevation, cathepsin inhibition, and autophagic flux stagnation. Lysosome-acidifying nanoparticles (AcNPs), originally developed to treat lysosomal storage disorders and neurodegenerative conditions like Parkinson's disease, effectively reverse these lysosomal deficits. The synthesis of this evidence indicates that AcNPs may serve as a cross-disciplinary solution for restoring lysosomal function compromised by chronic nanoplastic exposure.\n\n### [INTRODUCTION & JUSTIFICATION]\nLysosomal acidification is a fundamental biological requirement for cellular health. As established in the literature, \"Defects in lysosome/vacuole acidification are a conserved hallmark of aging and age-related diseases.\" In the context of pathology, environmental factors significantly disrupt this process. Specifically, \"PS-NP exposure hampered p62 degradation, leading to LC3B accumulation and decreased cathepsin B and D activity.\" Furthermore, in neurological models, \"\u03b1-synuclein preformed fibrils (\u03b1-syn PFF) impair lysosomal acidification in microglia, leading to defective autophagic flux and disrupted \u03b1-syn degradation.\"\n\nTo counteract these failures, engineered nanomaterials have shown significant therapeutic potential. \"In vitro, AcNPs effectively restored lysosomal pH, enhanced autophagic clearance of \u03b1Syn, improved mitochondrial function, and rescued A30P \u03b1Syn-induced cytotoxicity.\" The mechanism of these particles is well-defined: \"These nanomaterials were developed to locally acidify impaired lysosomes and restore their degradative capacity.\" This restorative mechanism is highly relevant to industrial or environmental toxicity, as evidenced by studies where \"acidic nanoparticles rescued lysosomal acidification and relieved the degenerative changes\" in models of cellular stress. By restoring pH, these platforms re-enable the \"cathepsin B activity\" and \"active cathepsin D\" required for the degradation of sequestered toxic substances. Consequently, the repurposing of AcNPs to remediate lysosomal damage from nanoplastics represents a logical intersection of nanomedicine and toxicology.\n\n### [DISCUSSION: NOVEL & OVERLOOKED]\n* **Lysosomal Vulnerability:** Lysosomes are not merely digestive organelles but central metabolic hubs that are hyper-sensitive to the physical accumulation of non-degradable synthetic materials like nanoplastics.\n* **Convergent Mechanisms:** Whether the stress is caused by genetic mutations (e.g., GBA1) or environmental pollution (e.g., PS-NPs), the outcome is a remarkably consistent convergence on V-ATPase-mediated acidification failure.\n* **Active Restoration:** The ability of exogenous particles to restore lysosomal pH (re-acidification) suggests that the underlying biological machinery of the lysosome remains functional if the proton gradient is artificially maintained or recovered.\n* **Plastic-Biofilm Synergy:** Some plastics, particularly when associated with microbial contaminants (e.g., PET b001), cause significantly higher pro-inflammatory responses than the polymer alone, adding a layer of biological complexity to nanoplastic-induced lysosomal damage.\n* **Therapeutic Potential of Acidification:** Restoring acidification is sufficient to rescue autophagy flux in diverse contexts, including silkworm mutants and aging chondrocytes, proving its utility as a pan-stress resilience mechanism.\n* **Chirality Impacts:** Nanoscale chirality modulates biological response, with specific enantiomers of gold nanoparticles altering inflammatory pathways by modulating lysosomal acidification, demonstrating that physical properties dictate toxicological potential.\n* **Nutraceutical Intervention:** The link between lysosomal acidification and cardiac aging via nicotinamide adenine dinucleotide metabolism suggests that dietary or pharmacological restoration of v-ATPase function can reverse markers of senescence in aging tissues.\n\n### [EVIDENCE, METHODOLOGY & CITATIONS]\n1.

Evidence confirms that nanoplastics (NPs) frequently disrupt lysosomal integrity, leading to alkalization and impaired degradative capacity. Conversely, engineered acidifying nanoparticles successfully restore lysosomal pH, autophagic flux, and mitochondrial function in several disease models, indicating high cross-applicability for managing environmental toxicant-driven organelle pathology.\n\n### [INTRODUCTION & JUSTIFICATION]\nEmerging literature establishes a clear mechanistic convergence between nanoplastic (NP) exposure and lysosomal pathology. Environmental contaminants, particularly polystyrene nanoplastics, consistently trigger lysosomal membrane permeabilization (LMP), alkalization, and the blockage of autophagic flux. The resulting reduction in cathepsin activity and clearance capacity directly contributes to neurodegenerative and metabolic disorders. Given that lysosome-acidifying nanoparticles have demonstrated the ability to rescue identical defects\u2014such as those induced by lipotoxicity, GBA1 mutations, or Alzheimer's-related protein aggregation\u2014it is mechanistically plausible that this platform can be adapted to mitigate nanoplastic-induced cytotoxicity. The restoration of acidic environments in lysosomes via pH-modulating materials addresses the primary functional deficiency caused by NP accumulation, thereby restoring proteostasis and cellular viability.\n\n### [DISCUSSION: NOVEL & OVERLOOKED]\n* Lysosomal alkalization induced by NPs acts as a \"degradative bottleneck,\" sharing distinct pathogenic features with familial Parkinson\u2019s disease and non-alcoholic fatty liver disease (NAFLD).\n* The \"Alkaline-Hammer\" strategy demonstrates that pH modulation can be used not only to rescue function but to actively induce \"alkaliptosis\" in targeted oncological applications.\n* Zinc-mediated lysosomal activation represents a non-nanoparticle alternative for achieving similar restorative outcomes in autophagic-lysosomal pathways.\n* There is a critical, size-dependent internalization mechanism for NPs; while 20-50 nm particles penetrate lysosomes readily, larger particles may rely on alternative phagocytic uptake mechanisms.\n* The restoration of lysosomal acidity is sufficient to reverse downstream mitochondrial dysfunction, positioning the lysosome as an upstream master regulator of bioenergetics.\n* Evidence suggests that the \"ECM-lysosome axis\" creates a self-amplifying pathological loop in degenerative conditions, which nanoparticles may interrupt.\n\n### [EVIDENCE, METHODOLOGY & CITATIONS]\n1.

"finalResponse": "Think of your cells as having \"trash compactors\" called lysosomes. These small, acidic compartments are responsible for breaking down waste, recycling materials, and keeping your cells healthy. When these compartments work properly, they remain acidic (low pH), which allows the enzymes inside them to cut through and clear out cellular debris [ID: 41533007].\n\nHowever, environmental pollutants like tiny nanoplastics can act like a \"wrench in the gears.\" When these plastics enter our cells, they often get stuck in these lysosomes, causing them to become less acidic, or \"alkalized.\" When the acidity is lost, the lysosome stops functioning\u2014it can no longer break down trash, and dangerous junk like damaged proteins or fats begins to pile up, which can eventually kill the cell [ID: 39740740, 40607257].\n\nScientists are now testing a promising solution: \"acidifying nanoparticles\" (AcNPs). Think of these as tiny, targeted medicine-delivery trucks that enter the cell, find the \"broken\" lysosomes, and pump acidity back into them [ID: 42033266]. By restoring the correct acid balance, these nanoparticles \"reset\" the trash compactor, allowing it to start clearing out the accumulated waste again [ID: 37142604]. \n\nEssentially, this is a way of repairing the cell\u2019s own natural cleaning system that has been jammed by environmental contaminants. While this technology has already shown great success in fixing similar problems related to diseases like Parkinson's, researchers believe it could be a powerful tool for cleaning up the damage caused by modern environmental stressors like nanoplastics [ID: 41247156, 42033266].",

Evidence confirms that nanoplastic-induced lysosomal dysfunction and alkalization are central features of cellular toxicity, and independent evidence confirms that lysosome-acidifying nanoparticles successfully restore lysosomal pH and degradative capacity in stressed models. While no study in the provided literature directly tests the cross-application of AcNPs for nanoplastic-induced damage, the mechanistic commonality of lysosomal alkalization suggests a potential for cross-platform adaptation.\n\n### [ABSTRACT & REWRITTEN CLAIM]\nLysosomal alkalization is a common pathological outcome of both neurodegenerative disease processes and environmental exposures, including nanoplastics. Experimental therapies utilizing pH-modulating nanomaterials have demonstrated success in restoring lysosomal acidity, enhancing autophagic flux, and preventing cell death. This evaluation synthesizes evidence regarding the structural and functional restoration of lysosomes to support the hypothesis that acidifying nanoplatforms can mitigate contaminant-induced lysosomal failure.\n\n### [INTRODUCTION & JUSTIFICATION]\nLysosomal homeostasis is essential for cellular quality control and degradative efficiency. Emerging research indicates that environmental stressors, such as nanoplastics and industrial toxins, specifically target the lysosomal apparatus, inducing alkalization, lysosomal membrane permeabilization, and autophagic blockades. \"These molecular alterations, together with lysosomal inhibition assays, functionally support lysosomal dysfunction as a key constraint on lipophagy.\" In parallel, engineered nanotechnologies have shown robust efficacy in reversing such deficits. \"These nanomaterials were developed to locally acidify impaired lysosomes and restore their degradative capacity.\" Furthermore, \"Restoring lysosomal acidity is important for maintaining enzymatic degradation, preventing protein aggregation, and reducing cellular waste accumulation in degenerating tissues.\" By integrating these findings, we observe that lysosome-acidifying agents function as a potential remedial node across multiple pathologies. \"Defective lysosomal acidification in astrocytes impairs their autophagic and phagocytic functions, resulting in the accumulation of cellular debris, excessive myelin and lipids, and toxic protein aggregates.\" Consequently, the adaptive utilization of AcNPs appears highly promising for reversing the loss of autophagic flux induced by environmental stressors.\n\n### [DISCUSSION: NOVEL & OVERLOOKED]\n* Lysosomal acidification strategies are effective across diverse pathological models, including proteinopathy, environmental toxicity, and metabolic disorders.\n* The V-ATPase is a shared primary target for both disease-associated lysosomal failure and contaminant-induced alkalization.\n* Nanoparticle surface modification (e.g., Cy3-labeling) is essential for monitoring the retention and longevity of pH-restoring agents within the acidic environment.\n* Lysosomal stress can trigger distinct pathways, such as non-canonical autophagy or the Conjugation of ATG8s to single membranes (CASM), as an adaptive response to toxin exposure.\n* The loss of lysosomal acidity is often directly linked to the initiation of necroptotic or apoptotic pathways, rendering pH restoration a cytoprotective necessity.\n* Some environmental toxins, like tributyltin, utilize the V-ATPase-ATG16L1 axis to modulate transcriptional programs like TFEB.\n* Cross-species evidence suggests that restoration of lysosomal function can mitigate inflammation and metabolic distress.\n\n### [EVIDENCE, METHODOLOGY & CITATIONS]\n1.

Evidence confirms that nanoplastics and other environmental contaminants frequently induce lysosomal dysfunction, including alkalization, blockade of autophagic flux, and cathepsin inhibition. The proposal that AcNPs could be repurposed to mitigate nanoplastic-induced toxicity is mechanistically plausible given the convergent pathways of lysosomal impairment, although direct experimental evidence of AcNP application to nanoplastic-induced lysosomal damage in vivo is currently limited.\n\n### [ABSTRACT & REWRITTEN CLAIM]\nLysosomal integrity is a critical requirement for maintaining cellular homeostasis, particularly in the clearance of protein aggregates and lipid metabolism. Environmental contaminants, such as polystyrene nanoplastics, frequently target the endolysosomal system, causing pH elevation, cathepsin inhibition, and autophagic flux stagnation. Lysosome-acidifying nanoparticles (AcNPs), originally developed to treat lysosomal storage disorders and neurodegenerative conditions like Parkinson's disease, effectively reverse these lysosomal deficits. The synthesis of this evidence indicates that AcNPs may serve as a cross-disciplinary solution for restoring lysosomal function compromised by chronic nanoplastic exposure.\n\n### [INTRODUCTION & JUSTIFICATION]\nLysosomal acidification is a fundamental biological requirement for cellular health. As established in the literature, \"Defects in lysosome/vacuole acidification are a conserved hallmark of aging and age-related diseases.\" In the context of pathology, environmental factors significantly disrupt this process. Specifically, \"PS-NP exposure hampered p62 degradation, leading to LC3B accumulation and decreased cathepsin B and D activity.\" Furthermore, in neurological models, \"\u03b1-synuclein preformed fibrils (\u03b1-syn PFF) impair lysosomal acidification in microglia, leading to defective autophagic flux and disrupted \u03b1-syn degradation.\"\n\nTo counteract these failures, engineered nanomaterials have shown significant therapeutic potential. \"In vitro, AcNPs effectively restored lysosomal pH, enhanced autophagic clearance of \u03b1Syn, improved mitochondrial function, and rescued A30P \u03b1Syn-induced cytotoxicity.\" The mechanism of these particles is well-defined: \"These nanomaterials were developed to locally acidify impaired lysosomes and restore their degradative capacity.\" This restorative mechanism is highly relevant to industrial or environmental toxicity, as evidenced by studies where \"acidic nanoparticles rescued lysosomal acidification and relieved the degenerative changes\" in models of cellular stress. By restoring pH, these platforms re-enable the \"cathepsin B activity\" and \"active cathepsin D\" required for the degradation of sequestered toxic substances. Consequently, the repurposing of AcNPs to remediate lysosomal damage from nanoplastics represents a logical intersection of nanomedicine and toxicology.\n\n### [DISCUSSION: NOVEL & OVERLOOKED]\n* **Lysosomal Vulnerability:** Lysosomes are not merely digestive organelles but central metabolic hubs that are hyper-sensitive to the physical accumulation of non-degradable synthetic materials like nanoplastics.\n* **Convergent Mechanisms:** Whether the stress is caused by genetic mutations (e.g., GBA1) or environmental pollution (e.g., PS-NPs), the outcome is a remarkably consistent convergence on V-ATPase-mediated acidification failure.\n* **Active Restoration:** The ability of exogenous particles to restore lysosomal pH (re-acidification) suggests that the underlying biological machinery of the lysosome remains functional if the proton gradient is artificially maintained or recovered.\n* **Plastic-Biofilm Synergy:** Some plastics, particularly when associated with microbial contaminants (e.g., PET b001), cause significantly higher pro-inflammatory responses than the polymer alone, adding a layer of biological complexity to nanoplastic-induced lysosomal damage.\n* **Therapeutic Potential of Acidification:** Restoring acidification is sufficient to rescue autophagy flux in diverse contexts, including silkworm mutants and aging chondrocytes, proving its utility as a pan-stress resilience mechanism.\n* **Chirality Impacts:** Nanoscale chirality modulates biological response, with specific enantiomers of gold nanoparticles altering inflammatory pathways by modulating lysosomal acidification, demonstrating that physical properties dictate toxicological potential.\n* **Nutraceutical Intervention:** The link between lysosomal acidification and cardiac aging via nicotinamide adenine dinucleotide metabolism suggests that dietary or pharmacological restoration of v-ATPase function can reverse markers of senescence in aging tissues.\n\n### [EVIDENCE, METHODOLOGY & CITATIONS]\n1.

Evidence confirms that nanoplastics (NPs) frequently disrupt lysosomal integrity, leading to alkalization and impaired degradative capacity. Conversely, engineered acidifying nanoparticles successfully restore lysosomal pH, autophagic flux, and mitochondrial function in several disease models, indicating high cross-applicability for managing environmental toxicant-driven organelle pathology.\n\n### [INTRODUCTION & JUSTIFICATION]\nEmerging literature establishes a clear mechanistic convergence between nanoplastic (NP) exposure and lysosomal pathology. Environmental contaminants, particularly polystyrene nanoplastics, consistently trigger lysosomal membrane permeabilization (LMP), alkalization, and the blockage of autophagic flux. The resulting reduction in cathepsin activity and clearance capacity directly contributes to neurodegenerative and metabolic disorders. Given that lysosome-acidifying nanoparticles have demonstrated the ability to rescue identical defects\u2014such as those induced by lipotoxicity, GBA1 mutations, or Alzheimer's-related protein aggregation\u2014it is mechanistically plausible that this platform can be adapted to mitigate nanoplastic-induced cytotoxicity.

Although environmentally aged MNPs predominate, their developmental toxicity remains poorly understood. We demonstrate that both pristine and aged polystyrene nanoplastics (PSNPs) induce abnormal lipid accumulation and impair early development in zebrafish larvae. Lipidomics revealed aged PSNPs significantly increased triglycerides via disrupted glycerophospholipid metabolism. Mechanistically, aged PSNPs did not alter LC3-II/LC3-I ratios but upregulated RAB7 and p62 while downregulating lysosomal biogenesis regulator TFEB. They also reduced ATG5, essential for autophagosome formation via LC3 lipidation. These molecular alterations, together with lysosomal inhibition assays, functionally support lysosomal dysfunction as a key constraint on lipophagy. This impairment inhibits lipid utilization, promotes accumulation, and disrupts development. Critically, aged PSNPs caused stronger disruption than pristine particles despite both interfering with lipophagy. Our study provides mechanistic insights into the developmental toxicity of UV-aged PSNPs in zebrafish, highlighting the importance of considering aging-related changes in nanoplastic risk evaluation. SYNOPSIS: Aged nanoplastics exacerbate developmental toxicity in zebrafish by suppressing lipophagy to drive lipid accumulation, underscoring ecological risks in aquatic systems."

It is characterized by the progressive loss of dopaminergic neurons in the substantia nigra and the accumulation of misfolded \u03b1-synuclein (\u03b1Syn) in intracellular inclusions known as Lewy bodies. Emerging evidence links \u03b1Syn accumulation to impaired lysosomal acidification and defective autophagy-lysosomal degradation, which are central to disease progression. To address this lysosomal dysfunction, we engineered a novel type of lysosome-targeted acidic nanoparticles (AcNPs) based on a biodegradable copolymer, poly(ethylene tetrafluorosuccinate-co-succinate) (PEFSU). These nanomaterials were developed to locally acidify impaired lysosomes and restore their degradative capacity. We evaluated their therapeutic potential in two familial PD models: SH-SY5Y neuroblastoma cells overexpressing A30P \u03b1Syn and A30P \u03b1Syn transgenic Drosophila melanogaster. In vitro, AcNPs effectively restored lysosomal pH, enhanced autophagic clearance of \u03b1Syn, improved mitochondrial function, and rescued A30P \u03b1Syn-induced cytotoxicity. In vivo, AcNPs treatment reduced \u03b1Syn burden, preserved dopaminergic neurons, and improved motor function in flies. This study demonstrates the first application of lysosome-acidifying polymeric nanoparticles in familial PD models and highlights the promise of rationally engineered pH-modulating nanomaterials as therapeutic agents for PD and other neurodegenerative diseases driven by lysosomal dysfunction and protein aggregation."

Restoring lysosomal acidity is important for maintaining enzymatic degradation, preventing protein aggregation, and reducing cellular waste accumulation in degenerating tissues. Acidic nanoparticles represent a promising therapeutic strategy to normalize lysosomal pH; however, accurate monitoring of their delivery, retention, and dosage is critical for rigorous evaluation. To address this, we developed fluorescently labeled poly(d,l-lactide-co-glycolide) (PLGA) nanoparticles conjugated with Cyanine3 amine (Cy3). Nanoparticle uptake was systematically optimized, achieving over 90% delivery to lysosomes of induced pluripotent stem cell-derived retinal pigment epithelial (iPS-RPE) cells, although uptake rates varied among adjacent cells. Once internalized, nanoparticles demonstrated remarkable stability, with no detectable change in concentration, distribution, or size for at least 28 days. iPS-RPE cells exhibited higher nanoparticle internalization compared with the ARPE-19 cell line and optic nerve head astrocytes. The capacity of the nanoparticles to restore function to stressed lysosomes was confirmed by their ability to reacidify lysosomes, restore cathepsin B activity, and increase the levels of active cathepsin D. The nanoparticles also reduced the levels of LC3II in astrocytes treated with chloroquine, indicating that they can also restore autophagy rates. In summary, this study demonstrates the value of Cy3 labeling for enhanced nanoparticle tracking to lysosomes. The findings also identify PLGA nanoparticles as powerful tools for restoring degradative lysosomal function and autophagy in cells undergoing lysosomal stress.NEW & NOTEWORTHY Tools that restore acidic pH in compromised lysosomes can enhance autophagy and waste clearance in degenerative disorders characterized by excessive accumulation. Here, we describe the synthesis of lysosome-targeted nanoparticles composed of poly(d,l-lactide-co-glycolide) (PLGA) polymers covalently bound to the fluorescent dye Cyanine3 amine (Cy3). These Cy3-PLGA nanoparticles enable precise tracking of lysosomal delivery and demonstrate sustained long-term retention within lysosomes, supporting their potential for future applications aimed at restoring lysosomal pH in aging and degenerating diseases."

Astrocytes also regulate neuronal functions and survival by modulating myelination and degradation of pathological toxic protein aggregates. Astrocytes have recently been proposed to possess both autophagic activity and active phagocytic capability which largely depend on sufficiently acidified lysosomes for complete degradation of cellular cargos. Defective lysosomal acidification in astrocytes impairs their autophagic and phagocytic functions, resulting in the accumulation of cellular debris, excessive myelin and lipids, and toxic protein aggregates, which ultimately contributes to the propagation of neuroinflammation and neurodegenerative pathology. Restoration of lysosomal acidification in impaired astrocytes represent new neuroprotective strategy and therapeutic direction. In this review, we summarize pathogenic factors, including neuroinflammatory signaling, metabolic stressors, myelin and lipid mediated toxicity, and toxic protein aggregates, that contribute to lysosomal acidification impairment and associated autophagic and phagocytic dysfunction in astrocytes. We discuss the role of lysosomal acidification dysfunction in astrocyte-mediated neuroinflammation primarily in the context of neurodegenerative diseases along with other brain injuries. We then highlight re-acidification of impaired lysosomes as a therapeutic strategy to restore autophagic and phagocytic functions as well as lysosomal degradative capacity in astrocytes. We conclude by providing future perspectives on the role of astrocytes as phagocytes and their crosstalk with other CNS cells to impart neurodegenerative or neuroprotective effects."

Mesenchymal stem cell-derived nanovesicle-poly(lactic-coglycolic acid) nanoparticles (MSC-PLGA-NPs) were prepared via sonication-loading. Blood-brain barrier (BBB) penetration was evaluated using in vitro transwell models and in vivo mouse models. Lysosomal function, autophagy, pathological protein clearance, and anti-inflammatory effects were assessed using various cellular and molecular biology techniques. MSC-PLGA-NPs demonstrated 2.3-fold higher BBB penetration efficiency compared to PLGA alone. In a chloroquine(CQ)-induced lysosomal injury model and mice model, they effectively restored lysosomal pH, enhanced autophagy (reducing LC3-II/I ratio by 0.4-fold and p62 expression by 52%), cleared amyloid precursor protein (APP) and phosphorylated tau (p-tau) proteins, and inhibited IL-6 and TNF-\u03b1 without hepatorenal toxicity. These results demonstrate that MSC-PLGA-NPs, a novel multifunctional nanoparticle platform, synergistically integrates the BBB penetration capability of MSC-NVs and the lysosomal acidification function of PLGA. The synergistic combination represents a pioneering \"delivery-repair-clearance\" integrated strategy for AD therapy.

Conjugation of ATG8s to single membranes (CASM) is a noncanonical LC3\u2011lipidation pathway activated by various stressors, distinct from canonical autophagy. We previously showed that TBT reduces lysosomal acidity and inhibits autophagy in SH-SY5Y cells. Furthermore, we observed TBT-induced LC3-II accumulation, which was reduced by bafilomycin A1, and tubular LC3-positive structures as hallmarks of CASM. In this study, we investigated whether TBT activates CASM. TBT (700\u00a0nM) induced LC3-II accumulation, which was completely blocked by bafilomycin A1 in SH-SY5Y and HeLa cells. Unlike autophagy, TBT induced LC3-II accumulation even under class III PI3K inhibition by wortmannin and in FIP200-knockout cells. Salmonella effector protein SopF, which inhibits V-ATPase-ATG16L1 association required for CASM, inhibited TBT-induced LC3-II accumulation. In FIP200-knockout cells, TBT induced LC3 accumulation on lysosomes, the primary CASM target. TBT also promoted nuclear translocation of transcription factor EB (TFEB) in a SopF-sensitive manner. Together, these results identify CASM as a lysosomal stress response to TBT, induced via the V-ATPase-ATG16L1 axis, leading to TFEB activation.

Consequently, the toxicology of such particles has emerged as a pivotal research interests in recent years. In this study, NP was synthesized successfully with an average particle size of 100\u00a0nm using a emulsion polymerization method as model particles. Following co-incubation of IEC-6 cells with NP for 24-168\u00a0h, a notable inhibition of cell viability and proliferation was observed. The significant activation of autophagy and a concomitant blockage of autophagic flux in IEC-6 cells after 24-72\u00a0h of co-incubation with NP were unveiled by transmission electron microscopy, western blotting, and double-fluorescent autophagy analysis. A significant increase in the number of lysosomes and an increase in the expression of hydrolase CTSB were detected, indicating dysregulation of lysosomal function. The subsequent transcriptomic and metabolomics analyses, coupled with the observation of activated lysosomes and the RIPK1-RIPK3-MLKL/PYGL pathway, led us to posit that the blockade of autophagy and lysosomal dysfunction, culminating in lysosomal membrane permeabilization (LMP) induced necroptosis, constitutes one of the mechanisms contributing to the cytotoxicity of NP.

This study found that nano-plastics may induce necroptosis in cells, and autophagy blockade and lysosomal dysfunction are prodromal manifestations."

However, antibiotic resistance has become a compelling health issue, leading to H. pylori eradication treatment failure worldwide. Additionally, the powerlessness of antibiotics against biofilms, as well as intracellular H. pylori and the long-term damage of antibiotics to the intestinal microbiota, have also created an urgent demand for antibiotic-free approaches. Herein, we describe an antibiotic-free, multifunctional copper-organic framework (HKUST-1) platform encased in a lipid layer comprising phosphatidic acid (PA), rhamnolipid (RHL), and cholesterol (CHOL), enveloped in chitosan (CS), and loaded in an ascorbyl palmitate (AP) hydrogel: AP@CS@Lip@HKUST-1. This platform targets inflammatory sites where H. pylori aggregates through electrostatic attraction. Then, hydrolysis by matrix metalloproteinases (MMPs) releases CS-encased nanoparticles, disrupting bacterial urease activity and membrane integrity. Additionally, RHL disperses biofilms, while PA promotes lysosomal acidification and activates host autophagy, enabling clearance of intracellular H. pylori. Furthermore, AP@CS@Lip@HKUST-1 alleviates inflammation and enhances mucosal repair through delayed Cu2+ release while preserving the intestinal microbiota. Collectively, this platform presents an advanced therapeutic strategy for eradicating persistent H. pylori infection without inducing drug resistance."

Targeting lysosomal functions with nanomaterials, such as DNA nanostructures (DNs), represents a rational and systematic way to control cell functionality. Here we present a versatile DNA nanostructure-based platform that can modulate a number of cellular functions depending on the concentration and surface decoration of the nanostructure. Utilizing different peptides for surface functionalization of DNs, we were able to rationally modulate lysosomal activity, which in turn translated into the control of cellular function, ranging from changes in cell morphology to modulation of immune signaling and cell death. Low concentrations of decalysine peptide-coated DNs induced lysosomal acidification, altering the metabolic activity of susceptible cells. In contrast, DNs coated with an aurein-bearing peptide promoted lysosomal alkalization, triggering STING activation. High concentrations of decalysine peptide-coated DNs caused lysosomal swelling, loss of cell-cell contacts, and morphological changes without inducing cell death. Conversely, high concentrations of aurein-coated DNs led to lysosomal rupture and mitochondrial damage, resulting in significant cytotoxicity. Our study holds promise for the rational design of a new generation of versatile DNA-based nanoplatforms that can be used in various biomedical applications, like the development of combinatorial anti-cancer platforms, efficient systems for endolysosomal escape, and nanoplatforms modulating lysosomal pH."

To disrupt this metabolic adaptability, we herein engineer a homotypic membrane-camouflaged nanomedicine capable of hypoxia-responsive cascade drug release and enhanced tumor accumulation. The resulting nanomedicine performs a hypoxia-induced phase transition that first liberates glucose oxidase to intensify oxygen deprivation and subsequently triggers burst release of chloroquine. Such a design of self-amplified relay drug release ensures effective starvation induction and precise lysosomal alkalization, thereby shutting down lysosome-mediated nutrient recycling.

However, this requires the use of excessive light energy to obtain good signal-to-noise ratio, which can then photobleach fluorochromes, and more worrisomely, lead to phototoxicity. Upon light excitation, noble metal nanoparticles such as silver nanoparticles (AgNPs) generate plasmons, which can then amplify excitation in direct proximity of the nanoparticle's surface and couple to the oscillating dipole of nearby radiating fluorophores, modifying their rate of emission and thus, enhancing their fluorescence. Here, we show that AgNPs fed to cells to accumulate within lysosomes enhanced the fluorescence of lysosome-targeted Alexa488-conjugated dextran, BODIPY-cholesterol, and DQ-BSA. Moreover, AgNP increased the fluorescence of GFP fused to the cytosolic tail of LAMP1, showing that metal enhanced fluorescence can occur across the lysosomal membrane. The inclusion of AgNPs in lysosomes did not disturb lysosomal properties such as lysosomal pH, degradative capacity, autophagy and autophagic flux, and membrane integrity, though AgNP seemed to increase basal lysosome tubulation. Importantly, by using AgNP, we could track lysosome motility with reduced laser power without damaging and altering lysosome dynamics. Overall, AgNP-enhanced fluorescence may be a useful tool to study the dynamics of the endo-lysosomal pathway while minimizing phototoxicity."

LRRK2 mutations increase the phosphorylation of Rab substrates including Rab12 and Rab10. Rab12 and Rab10 are expressed in neuronal and non-neuronal cells with localization to membranes in the endolysosomal compartment, and lysosomal stress activates LRRK2 phosphorylation of Rabs. In this study, using antibodies directed to the LRRK2-mediated phosphorylation sites on Rab12 at amino acid Ser106 (pS106-Rab12) and Rab10 at amino acid Thr73 (pT73-Rab10), we test whether aberrant LRRK2 phosphorylation is associated with tau and/or \u03b1-synuclein pathology across clinically distinct neurodegenerative diseases. Analysis of brain tissue lysates and immunohistochemistry of pathology-susceptible brain regions demonstrate that pS106-Rab12 levels are increased in Alzheimer's disease (AD) and Lewy body disease (LBD), including PD with and without G2019S LRRK2 mutation. At early pathological stages, phosphorylated Rab12 localizes to granulovacuolar degeneration bodies (GVBs), which are thought to be active lysosomal-like structures, in neurons. pS106-Rab12-positive GVBs accumulate with pathological tau across brain tissues in AD and LBD, and in G2019S LRRK2 mutation carriers. In a mouse model of tauopathy, pS106-Rab12 localizes to GVBs during early tau deposition in an age-dependent manner. While GVBs are largely absent in neurons with mature protein pathology, subsets of both tau and \u03b1-synuclein inclusions appear to incorporate pS106-Rab12 at later pathological stages. Further, pS106-Rab12 labels GVBs in neurons and shows co-pathology with tau inclusions in primary tauopathies including Pick's disease, progressive supranuclear palsy, and corticobasal degeneration. Finally, pT73-Rab10 is elevated and localizes to GVBs, but not tau and \u03b1-synuclein inclusions, in AD and LBD, including G2019S LRRK2 mutation carriers.

Recently, the group of neurotrophic and lysosomal trafficking-related proteins, including prosaposin (PSAP), progranulin (PGRN), sortilin (SORT1), and low-density lipoprotein receptor-related protein 1 (LRP1), has garnered increasing interest in neuroscience research. The aim of this study was to profile the post-mortem levels of PSAP, PGRN, SORT1 and LRP1, and to determine whether these biomarkers could serve as diagnostic tools for mechanistic stratification in forensic neuropathology and medico-legal investigations. The study involved a total of 40 cases, individuals with head injuries (n\u202f=\u202f20) suspected to be the cause of death and control atraumatic cases of sudden death (n\u202f=\u202f20) due to cardiopulmonary reasons. Serum and cerebrospinal fluid (CSF), were collected approximately 24\u202fh post-mortem and analyzed through ELISA testing. Brain specimens were obtained during forensic autopsies and subjected to immunohistochemical staining. We observed the elevated concentration level of PSAP in CSF, and the elevated concentration level of PGRN within serum and CSF. In the frontal cortex, anti-SORT1 and anti-LRP1 immunostaining revealed a general homogenization of the reaction in the study group. The molecular and cellular evidence suggests lysosomal trafficking disruption as central element of fatal TBI. The redistribution of SORT1 and LRP1, together with CSF-specific PSAP elevation and systemic PGRN increase, support a model in which neuronal lysosomal stress, receptor trafficking breakdown, and systemic release of lysosomal proteins are intertwined. The potential use of PSAP, PGRN, SORT1, and LRP1 assays offers an novel tool for research regarding TBI diagnosis and pathogenesis."

Extracellular vesicles (EVs) have attracted growing interest as therapeutic vehicles owing to their inherent capacity to bypass the blood-brain barrier and deliver complex biological cargo to the central nervous system. Here, we examined whether large EVs (LEVs) derived from microglia with stable Sirtuin-2 knockdown (SIRT2-KD) confer the neuroprotective effects associated with SIRT2 inhibition. LEVs harvested from SIRT2-KD microglia were administered intranasally to APP/PS1 mice. We assessed microglial uptake of LEVs, along with subsequent changes in cellular metabolism, migration toward amyloid-beta (A\u03b2) plaques, phagocytic activity, and downstream pathological and behavioral outcomes. Proteomic and acetylomic profiling were employed to characterize the molecular cargo of LEVs-SIRT2-KD. LEVs-SIRT2-KD were readily internalized by microglia in vivo following intranasal delivery. Uptake of these vesicles markedly enhanced microglial bioenergetics, driving coordinated upregulation of both oxidative phosphorylation and glycolysis. This metabolic shift was accompanied by improved microglial recruitment to A\u03b2 plaques and increased phagocytic clearance. Consequently, treated mice showed reduced A\u03b2 plaque deposition, restored synaptic integrity, and reversal of cognitive deficits. Proteomic and acetylomic analyses revealed that LEVs-SIRT2-KD are selectively enriched in proteins and acetylation modifications linked to energy metabolism and phagocytic function, offering a mechanistic basis for the observed metabolic reprogramming. Together, these results identify LEVs as a critical vesicle subtype mediating the effects of SIRT2 knockdown and support a cell-free therapeutic strategy for AD centered on EVs-driven metabolic reprogramming of microglia."

Dysfunction in beta-glucocerebrosidase (GCase) and leucine-rich repeat kinase 2 (LRRK2) mutation are genetic risks for developing synucleinopathies. However, whether pharmacological GCase activation ameliorated synucleinopathies in LRRK2-PD was unexplored. Here, we showed that long-term treatment of ambroxol (ABX), a brain-penetrant GCase activator, reduced \u03b1-syn oligomer accumulation in aged mutant LRRK2R1441G mouse striatum. Acute ABX treatment (50\u2009\u00b5M) increased cellular GCase enzymatic activity and reduced Ser129-\u03b1-syn phosphorylation in human SH-SY5Y cells and mutant LRRK2 mouse fibroblasts, independent to LRRK2 kinase activity. Real-time DQ-BSA assay revealed lysosomal dysfunction in mutant MEFs, which was partially attenuated by ABX treatment. Lysosomal stress by bafilomycin-A1 induced endogenous GCase activity in wildtype (WT) MEFs, which was not observed in the LRRK2 mutant. Single gavage of ABX (400\u2009mg/kg) in aged mice achieved peak drug level in serum and brain within 6\u2009h post-administration. Ad libitum feeding of ABX (in food pellets) over 18 weeks (average dose: 45.9\u2009mg/kg/day) elevated brain GCase activity in both WT and mutant striatum without affecting body weight. This regimen significantly reduced \u03b1-syn oligomer level in mutant striatum to a comparable physiological level in age-matched WT without altering total \u03b1-syn and Ser129-phosphorylation levels. This is the first study demonstrating reduced \u03b1-syn oligomer accumulation by chronic treatment of GCase activator in aged mouse brains vulnerable to PD, suggesting early intervention to alter progression of synucleinopathies as a key determinant of clinical outcomes of PD."

Mycolactone inhibits the Sec61-dependent co-translational translocation of signal peptide-bearing secreted and membrane proteins into the endoplasmic reticulum. Sec61 inhibition leads to accumulation of mislocalised proteins in the cytosol and initially triggers an integrated stress response-dependent activation of autophagy that contributes to cell survival. Here we show sustained exposure to mycolactone blocks late-stage autophagy and induces nuclear translocation of the lysosomal stress marker TFEB. This follows loss of ATP6AP1 and ATP6AP2, Sec61-substrates required for assembly of the Vacuolar-ATPase, leading to reduced lysosomal biogenesis and acidification. These effects are reduced in cells expressing a mycolactone-resistant Sec61\u03b1 mutant and phenocopied by other Sec61 inhibitors. Loss of lysosomal function compromises the cell's capacity to withstand the proteostatic stress caused by Sec61 inhibition and could impair the ability of phagocytes to combat infection with M. ulcerans and contribute to the tissue necrosis in Buruli ulcer. Furthermore, since Sec61 inhibition is being pursued as a therapeutic target in several diseases, potential drugs should be screened against this activity to avoid unwanted side-effects."

The HIV-1 envelope glycoprotein gp120 causes LSR, increases levels of ferrous iron (Fe2+) in the cytosol and in mitochondria, disrupts the reactive species interactome (RSI), and increases neural cell death. Using SH-SY5Y human neuroblastoma and U87MG human astrocytoma cells treated with gp120 and pharmacological modulators, we evaluated redox signaling and LSR by redox-sensitive fluorescent probes, spinning-disk confocal microscopy, flow cytometry, Western blotting, and immunostaining. Here, we report that TRPML1, an endolysosome redox-sensitive cation channel, is mechanistically involved in gp120-induced neurotoxicity. TRPML1 was activated by gp120-induced increases in cytosolic reactive oxygen species (ROS) and resulted in release of Fe2+ from endolysosomes in levels sufficient to increase cytosolic levels of Fe2+ and ROS as well as decrease levels of hydrogen sulfide (H2S). Reduced glutathione normally buffers intracellular Fe2+, but gp120 decreased endolysosome glutathione levels and disrupted this regulatory control mechanism thereby promoting TRPML1-mediated Fe2+ efflux from endolysosomes. TRPML1 redox activation led to changes to the RSI in endolysosomes including increased ROS, lipid peroxidation, nitric oxide, and sulfane sulfur as well as decreased H2S. These changes were accompanied by increased cysteine oxidation of luminal proteins and endolysosome deacidification. Pharmacological inhibition of TRPML1 or knocking down expression levels of TRPML prevented these effects. Our findings suggest that TRPML1 redox activation controls gp120-induced endolysosome dysfunction and iron/redox imbalance, and further implicates TRPML1 in the pathogenesis of HAND."

Tetracyclines, particularly doxycycline, have demonstrated multimodal neuroprotective effects, both in vitro and in vivo. The non-antibiotic derivative of doxycycline 4-dedimethylamino-12a-deoxydoxycycline (DDOX), has been recently shown to rescue neurons from oxidative injury. Here, we demonstrate that DDOX showcases a diverse range of mechanisms targeting \u03b1-Syn aggregates. Notably, DDOX inhibited the aggregation of \u03b1-Syn and the seeding ability of \u03b1-Syn pre-formed fibrils (PFF) in biophysical and cellular assays. In addition, the compound ameliorated the relocalization of total and phospho-\u03b1-Syn, triggered by exogenous \u03b1-Syn PFF. Surprisingly, DDOX drastically mitigated lysosomal stress induced by these aggregates. Moreover, we determined that DDOX effectively impeded the internalization of fluorescently labeled \u03b1-Syn PFF. Biophysical techniques and molecular docking simulations suggest that DDOX binds to hydrophobic patches on \u03b1-Syn fibrils. Our findings reveal novel neuroprotective attributes of tetracyclines, wherein a direct extracellular interaction between DDOX and \u03b1-Syn aggregated species mitigates their intracellular impact. These results provide a promising foundation for DDOX, a drug that aims to interfere with the intracellular seeding, propagation and uptake of \u03b1-Syn fibrils in neurodegenerative conditions."

Evidence confirms that nanoplastic-induced lysosomal dysfunction and alkalization are central features of cellular toxicity, and independent evidence confirms that lysosome-acidifying nanoparticles successfully restore lysosomal pH and degradative capacity in stressed models. While no study in the provided literature directly tests the cross-application of AcNPs for nanoplastic-induced damage, the mechanistic commonality of lysosomal alkalization suggests a potential for cross-platform adaptation.\n\n### [ABSTRACT & REWRITTEN CLAIM]\nLysosomal alkalization is a common pathological outcome of both neurodegenerative disease processes and environmental exposures, including nanoplastics. Experimental therapies utilizing pH-modulating nanomaterials have demonstrated success in restoring lysosomal acidity, enhancing autophagic flux, and preventing cell death. This evaluation synthesizes evidence regarding the structural and functional restoration of lysosomes to support the hypothesis that acidifying nanoplatforms can mitigate contaminant-induced lysosomal failure.\n\n### [INTRODUCTION & JUSTIFICATION]\nLysosomal homeostasis is essential for cellular quality control and degradative efficiency. Emerging research indicates that environmental stressors, such as nanoplastics and industrial toxins, specifically target the lysosomal apparatus, inducing alkalization, lysosomal membrane permeabilization, and autophagic blockades. \"These molecular alterations, together with lysosomal inhibition assays, functionally support lysosomal dysfunction as a key constraint on lipophagy.\" In parallel, engineered nanotechnologies have shown robust efficacy in reversing such deficits. \"These nanomaterials were developed to locally acidify impaired lysosomes and restore their degradative capacity.\" Furthermore, \"Restoring lysosomal acidity is important for maintaining enzymatic degradation, preventing protein aggregation, and reducing cellular waste accumulation in degenerating tissues.\" By integrating these findings, we observe that lysosome-acidifying agents function as a potential remedial node across multiple pathologies. \"Defective lysosomal acidification in astrocytes impairs their autophagic and phagocytic functions, resulting in the accumulation of cellular debris, excessive myelin and lipids, and toxic protein aggregates.\" Consequently, the adaptive utilization of AcNPs appears highly promising for reversing the loss of autophagic flux induced by environmental stressors.\n\n### [DISCUSSION: NOVEL & OVERLOOKED]\n* Lysosomal acidification strategies are effective across diverse pathological models, including proteinopathy, environmental toxicity, and metabolic disorders.\n* The V-ATPase is a shared primary target for both disease-associated lysosomal failure and contaminant-induced alkalization.\n* Nanoparticle surface modification (e.g., Cy3-labeling) is essential for monitoring the retention and longevity of pH-restoring agents within the acidic environment.\n* Lysosomal stress can trigger distinct pathways, such as non-canonical autophagy or the Conjugation of ATG8s to single membranes (CASM), as an adaptive response to toxin exposure.\n* The loss of lysosomal acidity is often directly linked to the initiation of necroptotic or apoptotic pathways, rendering pH restoration a cytoprotective necessity.\n* Some environmental toxins, like tributyltin, utilize the V-ATPase-ATG16L1 axis to modulate transcriptional programs like TFEB.\n* Cross-species evidence suggests that restoration of lysosomal function can mitigate inflammation and metabolic distress.\n\n### [EVIDENCE, METHODOLOGY & CITATIONS]\n1.

It is characterized by the progressive loss of dopaminergic neurons in the substantia nigra and the accumulation of misfolded \u03b1-synuclein (\u03b1Syn) in intracellular inclusions known as Lewy bodies. Emerging evidence links \u03b1Syn accumulation to impaired lysosomal acidification and defective autophagy-lysosomal degradation, which are central to disease progression. To address this lysosomal dysfunction, we engineered a novel type of lysosome-targeted acidic nanoparticles (AcNPs) based on a biodegradable copolymer, poly(ethylene tetrafluorosuccinate-co-succinate) (PEFSU). These nanomaterials were developed to locally acidify impaired lysosomes and restore their degradative capacity. We evaluated their therapeutic potential in two familial PD models: SH-SY5Y neuroblastoma cells overexpressing A30P \u03b1Syn and A30P \u03b1Syn transgenic Drosophila melanogaster. In vitro, AcNPs effectively restored lysosomal pH, enhanced autophagic clearance of \u03b1Syn, improved mitochondrial function, and rescued A30P \u03b1Syn-induced cytotoxicity. In vivo, AcNPs treatment reduced \u03b1Syn burden, preserved dopaminergic neurons, and improved motor function in flies. This study demonstrates the first application of lysosome-acidifying polymeric nanoparticles in familial PD models and highlights the promise of rationally engineered pH-modulating nanomaterials as therapeutic agents for PD and other neurodegenerative diseases driven by lysosomal dysfunction and protein aggregation.\n\nID: 41914166\nTitle: Nitrosylcobalamin Selectively Targets Tumors via Cobalamin Uptake and Lysosomal Processing.\nAbstract: Nitrosylcobalamin (NO-Cbl) is a vitamin B12 analog designed to exploit the \"Trojan horse\" vulnerability created by the heightened need of cancer cells for cobalamin and one-carbon metabolism. Building on our recent biophysical studies confirming the affinity of NO-Cbl for intrinsic factor, this work aimed to investigate the mechanistic basis for the selective anticancer activity of NO-Cbl through the cobalamin transport axis and lysosomal processing. Human cancer cell lines (NIH-OVCAR-3, MCF-7, WM9, and DU145) were cultured and transfected to overexpress transcobalamin II (TCII). Cell proliferation and cytotoxicity were measured using the sulforhodamine B (SRB) assay. TCII-R (CD320) expression was quantified by flow cytometry. The impact of anti-CD320 antiserum and lysosomal alkalization (chloroquine) on NO-Cbl activity was assessed. Antiserum inhibition of the TCII receptor resulted in dose-dependent inhibition of NIH-OVCAR-3 and MCF-7 cell proliferation. Lysosomal alkalinization by chloroquine pretreatment abrogated NO-Cbl-induced cytotoxicity in OVCAR-3 cells. Flow cytometric analysis demonstrated an inverse correlation between TCII-R (CD320) expression (MFI ratio) and NO-Cbl ID50. TCII overexpression significantly reduced NO-Cbl ID50 in NIH-OVCAR-3 cells. NO-Cbl utilizes tumor cell cobalamin transport and processing pathways to deliver nitric oxide selectively to cancer cells. These results, integrated with recent binding studies, validate NO-Cbl as a cobalamin-based targeted anticancer agent with efficacy in tumors expressing high levels of TCII and CD320.\n\nID: 41843675\nTitle: ATP13A2 restrains macrophage NLRP3 inflammasome activation to repress neurodegeneration via modulating mitochondrial homeostasis.\nAbstract: Neuro-immune crosstalk is increasingly recognized in Parkinson's disease (PD), and ATP13A2 is well known for its neuroprotective role. However, it remains unclear whether ATP13A2 mutations carried by PD patients contribute to immune dysfunction that exacerbates disease progression. Here, we systematically demonstrate that many ATP13A2 mutations result in a loss-of-expression phenotype. ATP13A2 is highly expressed in macrophages. Myeloid ATP13A2 deficiency causes uncontrolled NLRP3 inflammasome activation driven by lysosomal alkalization and subsequent disrupted mitochondrial homeostasis, rendering mice susceptible to a PD-like phenotype. PD-linked ATP13A2 loss-of-expression mutants fail to restore the ATP13A2 levels required to suppress NLRP3 hyperactivation in ATP13A2-depleted human THP-1 monocytes. Macrophages from a PD patient carrying the ATP13A2 loss-of-expression L927P mutation exhibit excessive NLRP3 activation due to lysosomal-mitochondrial dysfunction. Our findings provide insight into PD pathogenesis, emphasizing genetic factor-driven dysregulated macrophage NLRP3 activation, particularly in ATP13A2 loss-of-expression mutation cases.\n\nID: 41756019\nTitle: Real-time visualization of drug-target interactions in native subcellular microenvironments for lysosome-targeted drug discovery.\nAbstract: Conventional ex vivo drug screening platforms struggle to recapitulate native subcellular microenvironments, leading to high off-target rates and compromised discovery of bioactive compounds. To address this, we developed subcellular target-tracking fluorescent-visualization-based interaction screening (SubTrack-FVIS), a platform combining super-resolution imaging with target-specific fluorescent tagging. SubTrack-FVIS first maps nanoscale spatial distributions of drug targets within living cells, then screens compound libraries to identify molecules specifically binding to target-enriched domains, and finally quantifies drug-target interactions through super-resolution imaging tracking. Compared to traditional toolbox, SubTrack-FVIS reduces off-target effects by evaluating compound binding within native subcellular architectures. When applied to the lysosomal vacuolar H+-ATPases (V-ATPase) subunit, ATP6V1A, a validated anti-cancer target, this approach identified for lysosomal alkalization fluorescent drug (LAFD) as a potent inhibitor. Super-resolution imaging revealed LAFD's dynamic binding to ATP6V1A clusters, enabling real-time visualization of V-ATPase inhibition and subsequent lysosomal destabilization. Crucially, SubTrack-FVIS uncovered LAFD's unique mechanism of blocking autophagosome-lysosome fusion, resolving autophagic flux obstruction at sub-100 nm resolution. This platform establishes a visualization framework for discovering drugs within physiological subcellular contexts while simultaneously decoding their mechanistic impacts, offering application potential for target-centric drug development.\n\nID: 41702167\nTitle: Lipid metabolic dysregulation: A novel developmental toxicity pathway of aged nanoplastics via inhibition of lipophagy in zebrafish.\nAbstract: The widespread occurrence of micro/nanoplastics (MNPs) in ecosystems poses significant environmental challenges. Although environmentally aged MNPs predominate, their developmental toxicity remains poorly understood. We demonstrate that both pristine and aged polystyrene nanoplastics (PSNPs) induce abnormal lipid accumulation and impair early development in zebrafish larvae. Lipidomics revealed aged PSNPs significantly increased triglycerides via disrupted glycerophospholipid metabolism. Mechanistically, aged PSNPs did not alter LC3-II/LC3-I ratios but upregulated RAB7 and p62 while downregulating lysosomal biogenesis regulator TFEB. They also reduced ATG5, essential for autophagosome formation via LC3 lipidation. These molecular alterations, together with lysosomal inhibition assays, functionally support lysosomal dysfunction as a key constraint on lipophagy. This impairment inhibits lipid utilization, promotes accumulation, and disrupts development. Critically, aged PSNPs caused stronger disruption than pristine particles despite both interfering with lipophagy. Our study provides mechanistic insights into the developmental toxicity of UV-aged PSNPs in zebrafish, highlighting the importance of considering aging-related changes in nanoplastic risk evaluation. SYNOPSIS: Aged nanoplastics exacerbate developmental toxicity in zebrafish by suppressing lipophagy to drive lipid accumulation, underscoring ecological risks in aquatic systems.\n\nID: 41630134\nTitle: Self-Amplified Nanomedicine Enables Lysosomal Blockade to Potentiate Starvation Therapy of Pancreatic Ductal Adenocarcinoma.\nAbstract: Starvation therapy targeting the metabolic vulnerability of pancreatic ductal adenocarcinoma (PDAC) holds great potential; however, analyses of clinical samples and orthotopic models reveal that its efficacy is undermined by lysosome-mediated metabolic compensation. To disrupt this metabolic adaptability, we herein engineer a homotypic membrane-camouflaged nanomedicine capable of hypoxia-responsive cascade drug release and enhanced tumor accumulation. The resulting nanomedicine performs a hypoxia-induced phase transition that first liberates glucose oxidase to intensify oxygen deprivation and subsequently triggers burst release of chloroquine. Such a design of self-amplified relay drug release ensures effective starvation induction and precise lysosomal alkalization, thereby shutting down lysosome-mediated nutrient recycling. In a xenograft orthotopic PDAC model, this nanomedicine achieves 9.75-fold increase in tumor accumulation, robust tumor inhibition of 92.8%, and an elevated survival rate of 80% with favorable biosafety. Collectively, our findings highlight lysosomal disruption as a therapeutic lever to potentiate starvation therapy and provide a clinically actionable nanoplatform to enhance metabolic interventions for other metabolically vulnerable malignancies.\n\nID: 41395682\nTitle: Loss of RNASEK Terminates Egg Cylinder Development by Impairing Lysosomal Function Associated With V-ATPase in Mouse.\nAbstract: Although RNASEK is defined as a subunit of V-ATPase, how it regulates the V-ATPase and relevant physiological functions remains largely uncharacterized. Utilizing a homozygous RNASEK knockout mouse, we demonstrate that the null function of RNASEK leads to catastrophic developmental failure at the egg cylinder stage (E5.5). Rnasek-/- embryos exhibit pronounced lysosomal dysfunction and multilineage proliferation arrest, accompanied by the hallmarks of senescence, including elevated p21, reduced Ki67 and EdU incorporation as well as increased \u03b3H2AX foci, which are evident in\u00a0vitro embryo culture as well. Unexpectedly, despite increased V0/V1 subunit colocalization, lysosomal alkalization, proteolytic failure, and autophagic flux blockade collectively indicate that the loss of RNASEK promotes malfunctional V-ATPase assembly. Pharmacological restoration of lysosomal acidity via EN6 partially mitigates senescence and extends the developmental window. These findings demonstrate that RNASEK regulates lysosomal function via V-ATPase and is required for egg cylinder development in the mouse embryo. Loss of RNASEK promotes premature senescence of multiple cell lineages, terminating early embryonic development.\n\nID: 40662083\nTitle: Nurr1 deficiency impairs autophagy-lysosomal function through GBA-dependent transcriptional regulation in Parkinson's disease pathogenesis.\nAbstract: The autophagy-lysosomal pathway (ALP) dysfunction and lysosomal impairment contribute to the pathogenesis of Parkinson's disease (PD). Nuclear receptor related protein 1 (Nurr1) maintains the differentiation and maturation of dopaminergic neurons, and mutants or polymorphism in Nurr1 is associated with familial and sporadic PD. Previous studies on Nurr1 have mainly focused on the development and maintenance of midbrain dopaminergic neurons, while the potential involvement of Nurr1 in ALP regulation remains uncharacterized. Stable Nurr1 knockdown cells and inducible Nurr1 knockout mice were generated. Transcriptome sequencing and analysis was utilized to confirm the altered pathways and differentially expression genes associated with ALP. Transmission electron microscopy observation was conducted to find the ultrastructure differences between the Nurr1 knockdown cells and the controls. The expression of LC3B and the colocalization of LC3B and Lamp1 were assessed. Lysosomal acidity in the Nurr1 knockdown cells and the controls was measured. The expression of lysosomal proteins (Lamp 1/2, CTSD, and GBA) was determined in vitro and in vivo in the Nurr1-deficient models. Dual-luciferase reporter gene assay was performed to detect the transcriptional activity of GBA. The key lysosomal proteins (Lamp 1/2 and CTSD) were assessed after GBA overexpression. Twenty-two terms and 45 differentially expression genes associated with ALP were identified by transcriptome analysis. Knockdown of Nurr1 induced intracellular aggregation of autophagosomes, increased endogenous expression of LC3B II and elevated colocalization of exogenous GFP-LC3B with Lamp1. Lysosome dysfunction has been implicated with lysosomal alkalization and deprived level of lysosomal marker proteins with Nurr1 deficiency. GBA was transcriptionally downregulated by Nurr1 and Nurr1 deficiency-triggered lysosomal dysfunction were attenuated by GBA overexpression in the Nurr1 knockdown cells. Our study provided the first experimental evidence that Nurr1 deficiency induced lysosomal dysfunction by alkalizing the lumen of lysosomes and downregulating the key lysosomal protein (Lamp1, CTSD, and Lamp2) expression in vivo and in vitro. Defective lysosomal function compromised lysosomal mediated autophagic vesicle clearance. Mechanistically, Nurr1 transcriptionally regulated GBA expression, which in turn governed lysosomal marker protein homeostasis through a GBA-dependent axis. This study illuminated the involvement of Nurr1 in the ALP and the interaction between PD-related genes in the pathogenesis of PD.\n\nID: 40081223\nTitle: Ultrasound-triggered lysosomal alkalinization to block autophagy in tumor therapy.\nAbstract: Lysosomes play a crucial role in regulating cancer progression and drug resistance. However, there is a pressing need for the development of drugs that can safely and effectively modulate the pH of cancerous lysosomes in a controlled manner. In this study, we propose a novel strategy for lysosomal alkalinization triggered by piezoelectricity. Our findings indicate that the electrons generated by (BaTiO3/Zr/Ca) BCZT under sonication effectively alkalinize the lysosomes. Molecular dynamics simulations further demonstrate that alterations in lysosomal pH lead to modifications in the conformation of V-ATPase (proton pump), enhancing its interaction with sodium ions while partially excluding hydrogen ions from entering the lysosomes. This mechanism helps maintain lysosomal alkalization, resulting in reduced hydrolase activity and preventing the degradation of proteins and damaged organelles. The accumulation of nanoparticles within the lysosomes causes swelling and gradual destruction of the lysosomal membrane. Consequently, this lysosomal dysfunction hampers the fusion with autophagosomes, inhibiting autophagy in tumor cells and promoting apoptosis in various tumor types. Our strategy significantly inhibited tumor volume growth in mice during animal studies. In conclusion, our piezoelectric-triggered lysosomal alkalinization strategy holds promise for innovative breakthroughs in the treatment of multiple cancers.\n\nID: 40065324\nTitle: Lysosomal acidification impairment in astrocyte-mediated neuroinflammation.\nAbstract: Astrocytes are a major cell type in the central nervous system (CNS) that play a key role in regulating homeostatic functions, responding to injuries, and maintaining the blood-brain barrier. Astrocytes also regulate neuronal functions and survival by modulating myelination and degradation of pathological toxic protein aggregates. Astrocytes have recently been proposed to possess both autophagic activity and active phagocytic capability which largely depend on sufficiently acidified lysosomes for complete degradation of cellular cargos. Defective lysosomal acidification in astrocytes impairs their autophagic and phagocytic functions, resulting in the accumulation of cellular debris, excessive myelin and lipids, and toxic protein aggregates, which ultimately contributes to the propagation of neuroinflammation and neurodegenerative pathology. Restoration of lysosomal acidification in impaired astrocytes represent new neuroprotective strategy and therapeutic direction. In this review, we summarize pathogenic factors, including neuroinflammatory signaling, metabolic stressors, myelin and lipid mediated toxicity, and toxic protein aggregates, that contribute to lysosomal acidification impairment and associated autophagic and phagocytic dysfunction in astrocytes. We discuss the role of lysosomal acidification dysfunction in astrocyte-mediated neuroinflammation primarily in the context of neurodegenerative diseases along with other brain injuries. We then highlight re-acidification of impaired lysosomes as a therapeutic strategy to restore autophagic and phagocytic functions as well as lysosomal degradative capacity in astrocytes. We conclude by providing future perspectives on the role of astrocytes as phagocytes and their crosstalk with other CNS cells to impart neurodegenerative or neuroprotective effects.\n\nID: 39999611\nTitle: A \"turn-on\" intracellular pH probe for the quantitative monitoring of lysosomal alkalization in living cells.\nAbstract: A slight elevation in lysosomal pH can lead to indigestion or nonspecific hydrolysis, thereby increasing the risk of various neurodegenerative diseases and cancer. Therefore, accurate monitoring of lysosomal pH changes in living cells is essential for the diagnosis and treatment of such diseases, despite the significant challenges involved. In this study, we synthesized a pH-dependent fluorescent probe, B26, which comprises 1,8-naphthalimide as the fluorescent chromophore, an N-(2-hydroxyethyl) piperazine group for lysosome targeting, and a hydroxyethyl group to increase solubility and regulate pKa. B26 demonstrated high sensitivity, selectivity, and reversibility in response to H+, and exhibited a remarkable 98-fold increase in fluorescence intensity between pH 2.0 and pH 11.0, with a pKa value of 7.0, highlighting its \"turn-on\" fluorescence property. Density functional theory calculations and 1H NMR titration revealed that the pH-sensing mechanism of B26 relies on the inhibition of photoinduced electron transfer from the N-(2-hydroxyethyl) piperazine group to the naphthalimide moiety under acidic conditions. Importantly, B26 effectively labeled lysosomes and displayed significant sensitivity to pH changes, facilitating the quantitative detection of pH shifts during lysosomal alkalization in living cells due to its elevated pKa. These findings suggest that B26 successfully addresses the limitations of existing lysosomal pH probes, particularly in detecting pH changes within the near-neutral range. Furthermore, both the zebrafish model and subcutaneous imaging support the application of B26 in in vivo settings. Given its exceptional properties, B26 holds enormous potential for the research and diagnosis of pH-related diseases.\n\nID: 39828527\nTitle: Computer-Aided Design of Self-Assembled Nanoparticles to Enhance Cancer Chemoimmunotherapy via Dual-Modulation Strategy.\nAbstract: The rational design of self-assembled compounds is crucial for the highly efficient development of carrier-free nanomedicines. Herein, based on computer-aided strategies, important physicochemical properties are identified to guide the rational design of self-assembled compounds. Then, the pharmacophore hybridization strategy is used to design self-assemble nanoparticles by preparing new chemical structures by combining pharmacophore groups of different bioactive compounds. Hydroxychloroquine is grafted with the lipophilic vitamin E succinate and then co-assembled with bortezomib to fabricate the nanoparticle. The nanoparticle can reduce M2-type tumor-associated macrophages (TAMs) through lysosomal alkalization and induce immunogenic cell death (ICD) and nuclear factor-\u03baB (NF-\u03baB) inhibition in tumor cells. In mouse models, the nanoparticles induce decreased levels of M2-type TAMs, regulatory T cells, and transforming growth factor-\u03b2 (TGF-\u03b2), and increase the proportion of cytotoxicity T lymphocytes. Additionally, the nanoparticles reduce the secretion of Interleukin-6 (IL-6) by inhibiting NF-\u03baB and enhance the programmed death ligand-1 (PD-L1) checkpoint blockade therapy. The pharmacophore hybridization-derived nanoparticle provides a dual-modulation strategy to reprogram the tumor microenvironment, which will efficiently enhance the chemoimmunotherapy against triple-negative breast cancer.\n\nID: 39740740\nTitle: Nano-sized polystyrene plastics toxicity: Necroptosis pathway caused by autophagy blockade and lysosomal dysfunction.\nAbstract: The persistent detection of nano-sized plastic particles in humans, animals, and animal-derived products underscores the potential impact of these particles on living organisms. Consequently, the toxicology of such particles has emerged as a pivotal research interests in recent years. In this study, NP was synthesized successfully with an average particle size of 100\u00a0nm using a emulsion polymerization method as model particles. Following co-incubation of IEC-6 cells with NP for 24-168\u00a0h, a notable inhibition of cell viability and proliferation was observed. The significant activation of autophagy and a concomitant blockage of autophagic flux in IEC-6 cells after 24-72\u00a0h of co-incubation with NP were unveiled by transmission electron microscopy, western blotting, and double-fluorescent autophagy analysis. A significant increase in the number of lysosomes and an increase in the expression of hydrolase CTSB were detected, indicating dysregulation of lysosomal function. The subsequent transcriptomic and metabolomics analyses, coupled with the observation of activated lysosomes and the RIPK1-RIPK3-MLKL/PYGL pathway, led us to posit that the blockade of autophagy and lysosomal dysfunction, culminating in lysosomal membrane permeabilization (LMP) induced necroptosis, constitutes one of the mechanisms contributing to the cytotoxicity of NP. SYNOPSIS: The cytotoxicity and its related mechanisms of nano-plastic is still unclear. This study found that nano-plastics may induce necroptosis in cells, and autophagy blockade and lysosomal dysfunction are prodromal manifestations.\n\nID: 39372137\nTitle: Peptide-coated DNA nanostructures as a platform for control of lysosomal function in cells.\nAbstract: DNA nanotechnology is a rapidly growing field that provides exciting tools for biomedical applications. Targeting lysosomal functions with nanomaterials, such as DNA nanostructures (DNs), represents a rational and systematic way to control cell functionality. Here we present a versatile DNA nanostructure-based platform that can modulate a number of cellular functions depending on the concentration and surface decoration of the nanostructure. Utilizing different peptides for surface functionalization of DNs, we were able to rationally modulate lysosomal activity, which in turn translated into the control of cellular function, ranging from changes in cell morphology to modulation of immune signaling and cell death. Low concentrations of decalysine peptide-coated DNs induced lysosomal acidification, altering the metabolic activity of susceptible cells. In contrast, DNs coated with an aurein-bearing peptide promoted lysosomal alkalization, triggering STING activation. High concentrations of decalysine peptide-coated DNs caused lysosomal swelling, loss of cell-cell contacts, and morphological changes without inducing cell death. Conversely, high concentrations of aurein-coated DNs led to lysosomal rupture and mitochondrial damage, resulting in significant cytotoxicity. Our study holds promise for the rational design of a new generation of versatile DNA-based nanoplatforms that can be used in various biomedical applications, like the development of combinatorial anti-cancer platforms, efficient systems for endolysosomal escape, and nanoplatforms modulating lysosomal pH.\n\nID: 39261719\nTitle: Ammonia-induced lysosomal and mitochondrial damage causes cell death of effector CD8+ T cells.\nAbstract: Ammonia is thought to be a cytotoxin and its increase in the blood impairs cell function. However, whether and how this toxin triggers cell death under pathophysiological conditions remains unclear. Here we show that ammonia induces a distinct form of cell death in effector T cells. We found that rapidly proliferating T cells use glutaminolysis to release ammonia in the mitochondria, which is then translocated to and stored in the lysosomes. Excessive ammonia accumulation increases lysosomal pH and results in the termination of lysosomal ammonia storage and ammonia reflux into mitochondria, leading to mitochondrial damage and cell death, which is characterized by lysosomal alkalization, mitochondrial swelling and impaired autophagic flux. Inhibition of glutaminolysis or blocking lysosomal alkalization prevents ammonia-induced T cell death and improves T cell-based antitumour immunotherapy. These findings identify a distinct form of cell death that differs from previously known mechanisms.\n\nID: 39031462\nTitle: Lipopolysaccharide-Induced Lysosomal Cell Death Through Reactive Oxygen Species in Rat Liver Cell Clone 9.\nAbstract: In sepsis, bacterial components, particularly lipopolysaccharide (LPS), trigger organ injuries such as liver dysfunction. Although sepsis induces hepatocyte damage, the mechanisms underlying sepsis-related hepatic failure remain unclear. In this study, we demonstrated that the LPS-treated rat hepatocyte cell line Clone 9 not only induced reactive oxygen species (ROS) generation and apoptosis but also increased the expression of the autophagy marker proteins LC3-II and p62, and decreased the expression of intact Lamp2A, a lysosomal membrane protein. Additionally, LPS increased lysosomal membrane permeability and galectin-3 puncta formation, and promoted lysosomal alkalization in Clone 9 cells. Pharmacological inhibition of caspase-8 and cathepsin D (CTSD) suppressed the activation of caspase-3 and rescued the viability of LPS-treated Clone 9 cells. Furthermore, LPS induced CTSD release associated with lysosomal leakage and contributed to caspase-8 activation. Pretreatment with the antioxidant N-acetylcysteine (NAC) not only diminished ROS generation and increased the cell survival rate, but also decreased the expression of activated caspase-8 and caspase-3 and increased the protein level of Lamp2A in LPS-treated Clone 9 cells. These results demonstrate that LPS-induced ROS causes lysosomal membrane permeabilization and lysosomal cell death, which may play a crucial role in hepatic failure in sepsis. Our results may facilitate the development of new strategies for sepsis management.\n\nID: 38426215\nTitle: Single Fluorescent Probe for Multiple Tasks: Illuminating Lipid Droplets and Lysosomes in Dual Channels and Distinguishing Autophagy and Apoptosis.\nAbstract: Lipid droplets (LDs) and lysosomes play key roles in autophagy and cell apoptosis, and the discriminative visualization of the two organelles and simultaneously of autophagy and apoptosis is very helpful to understand their internal relationships. However, fluorescent probes that can concurrently achieve these tasks are not available currently. Herein, we delicately fabricate a robust probe CAQ2 for multiple tasks: illumination of LDs and lysosomes in dual emission colors as well as discriminative visualization of cell apoptosis and autophagy. The probe exhibited both lipophilic and basic properties and displayed different emission colors in neutral and protonated forms; thus, LDs and lysosomes emitted blue and red fluorescence colors, respectively. Because of the lysosomal acidification during autophagy, CAQ2 detected autophagy with evidently enhanced red emission. Because of the lysosomal alkalization during apoptosis, CAQ2 imaged apoptosis with a drastically decreased red fluorescence intensity. With the robust probe, the autophagy under starvation and lipidless conditions was visualized, and the apoptosis induced by H2O2, ultraviolet (UV) irradiation, and rotenone treatment was successfully observed. The efficient detoxification of Na2S against rotenone treatment was successfully revealed.\n\nID: 37742976\nTitle: Lysosomal dysfunction in carbon black-induced lung disorders.\nAbstract: Carbon black (CB), a component of environmental particulate pollution derived from carbon sources, poses a significant threat to human health, particularly in the context of lung-related disease. This study aimed to investigate the detrimental effects of aggregated CB in the average micron scale on lung tissues and cells in vitro and in vivo. We observed that CB particles induced lung disorders characterized by enhanced expression of inflammation, necrosis, and fibrosis-related factors in vivo. In alveolar epithelial cells, CB exposure resulted in decreased cell viability, induction of cell death, and generation of reactive oxidative species, along with altered expression of proteins associated with lung disorders. Our findings suggested that the damaging effects of CB on the lung involved the targeting of lysosomes. Specifically, CB promoted lysosomal membrane permeabilization, while lysosomal alkalization mitigated the harmfulness of CB on lung cells. Additionally, we explored the protective effects of alkaloids derived from Nelumbinis plumula, with a focus on neferine, against CB-induced lung disorders. In conclusion, these findings contribute to a deeper understanding of the pathophysiological effects of CB particles on the lungs and propose a potential therapeutic approach for pollution-related diseases.\n\nID: 37488886\nTitle: Recent progress and future directions of the research on nanoplastic-induced neurotoxicity.\nAbstract: Many types of plastic products, including polystyrene, have long been used in commercial and industrial applications. Microplastics and nanoplastics, plastic particles derived from these plastic products, are emerging as environmental pollutants that can pose health risks to a wide variety of living organisms, including humans. However, it is not well understood how microplastics and nanoplastics affect cellular functions and induce stress responses. Humans can be exposed to polystyrene-microplastics and polystyrene-nanoplastics through ingestion, inhalation, or skin contact. Most ingested plastics are excreted from the body, but inhaled plastics may accumulate in the lungs and can even reach the brain via the nose-to-brain route. Small-sized polystyrene-nanoplastics can enter cells by endocytosis, accumulate in the cytoplasm, and cause various cellular stresses, such as inflammation with increased pro-inflammatory cytokine production, oxidative stress with generation of reactive oxygen species, and mitochondrial dysfunction. They induce autophagy activation and autophagosome formation, but autophagic flux may be impaired due to lysosomal dysfunction. Unless permanently exposed to polystyrene-nanoplastics, they can be removed from cells by exocytosis and subsequently restore cellular function. However, neurons are very susceptible to this type of stress, thus even acute exposure can lead to neurodegeneration without recovery. This review focuses specifically on recent advances in research on polystyrene-nanoplastic-induced cytotoxicity and neurotoxicity. Furthermore, in this review, based on mechanistic studies of polystyrene-nanoplastics at the cellular level other than neurons, future directions for overcoming the negative effects of polystyrene-nanoplastics on neurons were suggested.\n\nID: 37405751\nTitle: Improved imaging and preservation of lysosome dynamics using silver nanoparticle-enhanced fluorescence.\nAbstract: The dynamics of living cells can be studied by live-cell fluorescence microscopy. However, this requires the use of excessive light energy to obtain good signal-to-noise ratio, which can then photobleach fluorochromes, and more worrisomely, lead to phototoxicity. Upon light excitation, noble metal nanoparticles such as silver nanoparticles (AgNPs) generate plasmons, which can then amplify excitation in direct proximity of the nanoparticle's surface and couple to the oscillating dipole of nearby radiating fluorophores, modifying their rate of emission and thus, enhancing their fluorescence. Here, we show that AgNPs fed to cells to accumulate within lysosomes enhanced the fluorescence of lysosome-targeted Alexa488-conjugated dextran, BODIPY-cholesterol, and DQ-BSA. Moreover, AgNP increased the fluorescence of GFP fused to the cytosolic tail of LAMP1, showing that metal enhanced fluorescence can occur across the lysosomal membrane. The inclusion of AgNPs in lysosomes did not disturb lysosomal properties such as lysosomal pH, degradative capacity, autophagy and autophagic flux, and membrane integrity, though AgNP seemed to increase basal lysosome tubulation. Importantly, by using AgNP, we could track lysosome motility with reduced laser power without damaging and altering lysosome dynamics. Overall, AgNP-enhanced fluorescence may be a useful tool to study the dynamics of the endo-lysosomal pathway while minimizing phototoxicity.\n\nID: 37104743\nTitle: Migration from Lysosome to Nucleus: Monitoring Lysosomal Alkalization-Related Biological Processes with an Aminofluorene-Based Probe.\nAbstract: Aberrant lysosomal alkalization is associated with various biological processes, such as oxidative stress, cell apoptosis, ferroptosis, etc. Herein, we developed a novel aminofluorene-based fluorescence probe named FAN to monitor the lysosomal alkalization-related biological processes by its migration from lysosome to nucleus. FAN possessed NIR emission, large Stokes shift, high pH stability, and high photostability, making it suitable for real-time and long-term bioimaging. As a lysosomotropic molecule, FAN can accumulate in lysosomes first and then migrate to the nucleus by right of its binding capability to DNA after lysosomal alkalization. In this manner, FAN was successfully used to monitor these physiological processes which triggered lysosomal alkalization in living cells, including oxidative stress, cell apoptosis, and ferroptosis. More importantly, at higher concentrations, FAN could also serve as a stable nucleus dye for the fluorescence imaging of the nucleus in living cells and tissues. This novel multifunctional fluorescence probe shows great promise for application in lysosomal alkalization-related visual research and nucleus imaging.\n\nID: 36736819\nTitle: Maltol attenuates polystyrene nanoplastic-induced enterotoxicity by promoting AMPK/mTOR/TFEB-mediated autophagy and modulating gut microbiota.\nAbstract: The production and application of nanoplastics has been increased during decades, and the enterotoxicity caused by their bioaccumulation has attracted vast attention. Maltol was proved to exert a protective effect on gut damage induced by carbon tetrachloride and cisplatin, indicating its confrontation with nanoplastics-induced intestinal toxicity. To explore the ameliorative effects of maltol on polystyrene nanoplastics (PS)-mediated enterotoxicity and the underlying mechanism, the mice were exposed to PS (100\u00a0mg/kg), combining with or without the treatment of maltol treatment at 50 and 100\u00a0mg/kg. We found PS exposure caused intestinal barrier damage and enterocyte apoptosis, while lysosomal dysfunction and autophagic substrate degradation arrest in enterocytes of mice were also observed. In addition, PS exacerbated the disturbance of the intestinal microbial community, affected the abundance of lysosome and apoptosis-related bacterial genes, and decreased the number of known short-chain fatty acid (SCFA) producing bacteria. However, those alterations were improved by the maltol treatment. Maltol also protected the human intestinal Caco-2\u00a0cells from PS-induce damages. Mechanistic studies showed maltol promoted TFEB nuclear translocation through the AMPK/mTOR signaling pathway to restore lysosomal function and reduce autophagy dependent apoptosis. The findings in the present work might help to elucidate the potential molecular mechanisms of PS-induced enterotoxicity. For the first time to our knowledge, the protective effect of maltol on PS-induced intestinal injury was studied from multiple perspectives, which provided a potential therapeutic approach for diseases caused by environmental pollution.\n\nID: 36108847\nTitle: Responses of zebrafish (Danio rerio) cells to antibiotic erythromycin stress at the subcellular levels.\nAbstract: Erythromycin (ERY) is one of the most used antibiotics frequently detected in different aquatic environments and may bring burdens to aquatic ecosystems. However, the impacts of antibiotics on aquatic systems other than the antibiotic resistance genes remain largely unknown. In the present study, the responses to ERY exposure at the subcellular-organelle levels were for the first time investigated and imaged over 24 h. Exposure to ERY hampered the zebrafish (Danio rerio) cell growth and decreased the cell viability in a time-dependent mode. Meanwhile, exposure to a low concentration of ERY (73.4 \u03bcg L-1) induced reactive oxygen species (ROS) overproduction and lysosomal damage following lysosomal alkalization and swelling. In turn, the lysosomal stress was the major driver of altering the ROS level, superoxide dismutase (SOD) activity, and glutathione (GSH) content. Subsequently, mitochondria displayed dysfunction such as increased mitochondrial ROS, impaired mitophagy, and induced mitochondria-driven apoptosis, as well as impaired mitochondrial electron transport chain and loss of membrane potential. These results collectively demonstrated the subcellular sensitive machinery responses to ERY stress at environmentally relevant and slightly higher sub-lethal concentrations. ERY may induce switching from autophagy to apoptosis with corresponding changes in lysosomal activity, antioxidant activity, and mitochondrial activity. The findings provided important information on the physiological and subcellular responses of fish cells to ERY.\n\nID: 35785701\nTitle: Lysosomal sequestration of weak base drugs, lysosomal biogenesis, and cell cycle alteration.\nAbstract: Lysosomes, now known to take part in multiple cellular functions, also respond to various stress stimuli. These include biogenesis in response to nanomolar concentrations of hydrophobic weak-base anticancer drugs. However, since lysosomal stress mediated by accumulation of weak-base drugs at such concentrations has never been proven and these drugs have diverse effects on malignant cells, we investigated whether the interpretation of the data was true. We found that lysosomal accumulation of the drugs daunorubicin, doxorubicin, mitoxantrone, symadex, chloroquine, clomipramine and sunitinib alone, was insufficient to induce lysosomal alkalization i.e., lysosomal stress-mediated biogenesis at nanomolar concentrations. Instead, we found that some of the drugs used induced G2 phase arrest and lysosomal biogenesis that is associated with activation of transcription factor EB (TFEB). Similarly, cantharidin, a control compound that does not belong to the weak base drugs, induced cell cycle arrest in the G2 phase associated with TFEB-driven lysosomal biogenesis. Overall none of the tested drugs caused stress-induced lysosomal biogenesis at nanomolar concentrations. However, daunorubicin, doxorubicin, mitoxantrone, symadex and cantharidin induced a massive block in the G2 phase of the cell cycle which is naturally associated with TFEB-driven lysosomal biogenesis.\n\nID: 35022393\nTitle: Danger signal extracellular calcium initiates differentiation of monocytes into SPP1/osteopontin-producing macrophages.\nAbstract: The danger signal extracellular calcium is pathophysiologically increased in the synovial fluid of patients with rheumatoid arthritis (RA). Calcium activates the NLRP3-inflammasome via the calcium-sensing receptor in monocytes/macrophages primed by lipopolysaccharide, and this effect is mediated by the uptake of calciprotein particles (CPPs) formed out of calcium, phosphate, and fetuin-A. Aim of the study was to unravel the influence of calcium on monocytes when the priming signal is not present. Monocytes were isolated from the blood of healthy controls and RA patients. Macrophages were characterized using scRNA-seq, DNA microarray, and proteomics. Imaging flow cytometry was utilized to study intracellular events. Here we show that extracellular calcium and CPPs lead to the differentiation of monocytes into calcium-macrophages when the priming signal is absent. Additional growth factors are not needed, and differentiation is triggered by calcium-dependent CPP-uptake, lysosomal alkalization due to CPP overload, and TFEB- and STAT3-dependent increased transcription of the lysosomal gene network. Calcium-macrophages have a needle-like shape, are characterized by excessive, constitutive SPP1/osteopontin production and a strong pro-inflammatory cytokine response. Calcium-macrophages differentiated out of RA monocytes show a stronger manifestation of this phenotype, suggesting the differentiation process might lead to the pro-inflammatory macrophage response seen in the RA synovial membrane.\n\nID: 34445748\nTitle: Targeting Lysosomes to Reverse Hydroquinone-Induced Autophagy Defects and Oxidative Damage in Human Retinal Pigment Epithelial Cells.\nAbstract: In age-related macular degeneration (AMD), hydroquinone (HQ)-induced oxidative damage in retinal pigment epithelium (RPE) is believed to be an early event contributing to dysregulation of inflammatory cytokines and vascular endothelial growth factor (VEGF) homeostasis. However, the roles of antioxidant mechanisms, such as autophagy and the ubiquitin-proteasome system, in modulating HQ-induced oxidative damage in RPE is not well-understood. This study utilized an in-vitro AMD model involving the incubation of human RPE cells (ARPE-19) with HQ. In comparison to hydrogen peroxide (H2O2), HQ induced fewer reactive oxygen species (ROS) but more oxidative damage as characterized by protein carbonyl levels, mitochondrial dysfunction, and the loss of cell viability. HQ blocked the autophagy flux and increased proteasome activity, whereas H2O2 did the opposite. Moreover, the lysosomal membrane-stabilizing protein LAMP2 and cathepsin D levels declined with HQ exposure, suggesting loss of lysosomal membrane integrity and function. Accordingly, HQ induced lysosomal alkalization, thereby compromising the acidic pH needed for optimal lysosomal degradation. Pretreatment with MG132, a proteasome inhibitor and lysosomal stabilizer, upregulated LAMP2 and autophagy and prevented HQ-induced oxidative damage in wildtype RPE cells but not cells transfected with shRNA against ATG5. This study demonstrated that lysosomal dysfunction underlies autophagy defects and oxidative damage induced by HQ in human RPE cells and supports lysosomal stabilization with the proteasome inhibitor MG132 as a potential remedy for oxidative damage in RPE and AMD.\n\nID: 33962064\nTitle: Lysosomal alkalization to potentiate eradication of intra-osteoblastic Staphylococcus aureus in the bone and joint infection setting.\nAbstract: Beyond intracellular penetration, acidic lysosomal pH might affect the intracellular activity of some antimicrobials. This study evaluated the ability of lysosomotropic alkalizing agents to potentiate the antimicrobial eradication of an intra-osteoblastic Staphylococcus aureus reservoir in the setting of bone and joint infection (BJI). MICs of 16 anti-staphylococcal molecules active against methicillin-sensitive S.\u00a0aureus (MSSA) were evaluated at pH 5 and pH 7. Additionally, the lysosomal alkalizing potential (spectrofluorometry) and cytotoxicity (MTT assay) of hydroxychloroquine, amantadine and ammonium chloride were assessed. The results led to further investigation of clindamycin, cotrimoxazole, daptomycin and levofloxacin-alone or in combination with hydroxychloroquine-in an in\u00a0vitro model of osteoblast infection. The impact of hydroxychloroquine on autophagy was finally investigated using Western blot detection of two autophagic flux indicators, the LC3 membrane protein and the SQSTM1 cargo protein. Daptomycin, cotrimoxazole, clindamycin and levofloxacin alone significantly decreased the intracellular staphylococcal reservoir (5.12 log10\u00a0CFU/100\u00a0000\u00a0cells) by 0.14 (95%CI 0.01-0.34), 0.25 (95%CI 0.12-0.43), 0.16 (95%CI 0.004-0.39) and 1.18 (95%CI 1.04-1.38) log10\u00a0CFU/100\u00a0000\u00a0cells, respectively (p\u00a0<\u00a010-3). Adding hydroxychloroquine (20 mg/L) increased intralysosomal pH from 4.8 to 7, and concomitantly the inoculum of each antimicrobial was reduced by 0.50 (95%CI 0.30-0.84), 0.73 (95%CI 0.59-0.96), 0.59 (95%CI 0.46-0.78) and 1.8 (95%CI 1.66-2.1) log10\u00a0CFU/100\u00a0000\u00a0cells, respectively (p\u00a0<\u00a010-4). Cellular levels of LC3II and SQSTM1 showed that hydroxychloroquine has direct activity on the autophagic flux, fostering the eradication of intracellular S.\u00a0aureus by antimicrobials. At high concentrations, hydroxychloroquine used as an adjuvant to antimicrobials improves eradication of an S.\u00a0aureus intra-osteoblastic reservoir in our in\u00a0vitro cell infection model. These findings advocate further in\u00a0vivo evaluation of alkalization efficacy and tolerance in S.\u00a0aureus BJI.\n\nID: 33838376\nTitle: PM2.5 and the typical components cause organelle damage, apoptosis and necrosis: Role of reactive oxygen species.\nAbstract: In this research, the organelle damage, apoptosis and necrosis induced by PM2.5, BC and Kaolin were studied using human bronchial epithelial (16HBE) cells. PM2.5, BC and Kaolin all induce cell death, LDH release and excess intracellular ROS generation. For the organelle injuries, Kaolin and high-dose PM2.5 (240 \u03bcg/mL) cause lysosomal acidification, but BC causes lysosomal alkalization (lysosomal membrane permeabilization, LMP). BC and Kaolin cause the loss of mitochondrial membrane potential (MMP), while PM2.5 does not. For the cell death mode, PM2.5 causes both apoptosis and necrosis. However only necrosis has been detected in the BC and Kaolin treated groups, indicating the more severe cellular insult. Excess ROS generation is involved in the organelle damage and cell death. ROS contributes to the BC-induced LMP and necrosis, but does not significantly affect the Kaolin-induced MMP loss and necrosis. Therefore, the BC component in PM2.5 may cause cytotoxicity via ROS-dependent pathways, the Kaolin component may damage cells via ROS-independent mechanisms such as strong interaction. The PM2.5-induced apoptosis and necrosis can be partially mitigated after the removal of ROS, indicating the existence of both the ROS-dependent and ROS-independent mechanisms due to the complicated PM2.5 components. BC represents the anthropogenic source component in PM2.5, while Kaolin represents the natural source component. Our results provide knowledge on the toxic mechanisms of typical PM2.5 components at the cellular and subcellular levels.\n\nID: 36132550\nTitle: Chemosensitivity enhanced by autophagy inhibition based on a polycationic nano-drug carrier.\nAbstract: In recent years, with the increasing understanding of the role of autophagy in tumorigenesis and development, a steady stream of studies have demonstrated that both excessive induction and inhibition of autophagy could effectively improve the therapeutic efficacy against tumors during cytotoxic or molecularly targeted drug therapy. Among them, autophagy inhibition mediated by nanomaterials has become an appealing notion in nanomedicine therapeutics, since it can be exploited as an effective adjuvant in chemotherapy or as a potential anti-tumor agent. Herein, we constructed a pH-sensitive nanoplatform loaded with epirubicin (EPI) (mPEG-b-P(DPA-b-DMAEMA)/EPI), enabling effective autophagy inhibition in the process of tumor-targeting therapy and further sensitized the tumors to EPI. It was found that polycationic nanomicelles (PEDD-Ms) displayed specific localization in lysosomes after entering tumor cells and caused the impairment of lysosomal degradation capacity through lysosomal alkalization in a dose-dependent manner. HepG2 cells treated with PEDD-Ms displayed a large-scale accumulation of autophagosomes and LC3 (an autophagosome marker protein), and the degradation of the autophagy substrate p62 was also blocked, which indicated that these functional nanomicelles could significantly inhibit autophagy. Meanwhile, the typical morphological characteristics of autophagosomes were directly visualized by TEM. In vivo results also showed that the tumor-targeted and autophagy inhibition-associated nanoplatform therapy could effectively improve the therapeutic efficiency of EPI, which may be partially attributed to the fact that autophagy inhibition could enhance the sensitivity of tumor cells to EPI. Overall, we revealed the effect of polycationic nanomicelles on autophagic processes in tumor cells and explored their possible molecular mechanism, also considering the synergistic outcome between autophagy mediated by nanomaterials and chemotherapeutic drugs to improve the therapeutic effect on tumors.\n\nID: 33396069\nTitle: Quercetin alleviates Cadmium-induced autophagy inhibition via TFEB-dependent lysosomal restoration in primary proximal tubular cells.\nAbstract: Autophagy dysregulation plays a pivotal role in cadmium (Cd)-induced nephrotoxicity. Quercetin (Qu), a flavonoid antioxidant with autophagy-enhancing effect, has protective effect on Cd-induced toxicity, but whether it can prevent Cd-induced nephrotoxicity via restoration of autophagy remains unknown. Here, primary rat proximal tubular (rPT) cells were exposed to Cd and/or Qu in vitro to clarify this issue. Data first showed that Cd-impaired autophagic flux was markedly alleviated by Qu, including decreased levels of autophagy marker proteins and recovery of autophagosome-lysosome fusion targeted for lysosomes. Meanwhile, Cd-induced lysosomal alkalization due to v-ATPases inhibition was prominently recovered by Qu. Accordingly, Qu enhanced Cd-diminished lysosomal degradation capacity and lysosome-related gene transcription levels. Notably, Qu improved Cd-inhibited TFEB nuclear translocation and its gene transcription level. Furthermore, data showed that the restoration of Cd-impaired autophagy-lysosome pathway and resultant alleviation of cytotoxicity by Qu are TFEB-dependent using TFEB gene silencing and overexpression technologies. In summary, these data provide novel evidences that the protective action of Qu against Cd-induced autophagy inhibition is attributed to its restoration of lysosomal dysfunction, which is dependent on TFEB.\n\nID: 42479449\nTitle: Does the Evidence Support High-Dose Liposomal Amphotericin B in the Treatment of Mucormycosis?\nAbstract: Guidelines recommend liposomal amphotericin B (L-AMB) at 5-10\u2005mg/kg/day as first-line therapy for invasive mucormycosis, but whether doses exceeding 5-6\u2005mg/kg/day improve outcomes enough to justify added nephrotoxicity and cost remains unclear. We critically appraised pharmacokinetic, preclinical, and clinical evidence from 58 publications, defining standard-dose L-AMB as 5-6\u2005mg/kg/day and high-dose (HD) L-AMB as >6\u2005mg/kg/day. Animal models show dose-dependent efficacy, but the only prospective trial (Ambizygo) examining HD-L-AMB was a single-arm pilot trial whose response rates were similar to historical 5\u2005mg/kg/day cohorts. Retrospective studies have not found survival benefit favoring HD L-AMB, with consistently higher rates of nephrotoxicity. Saturable pharmacokinetics and altered liposome distribution at doses >10\u2005mg/kg/day may explain this lack of benefit. Routine dose escalation beyond 5-6\u2005mg/kg/day is not supported by current evidence; early diagnosis, surgical debridement, and reversal of immunosuppression appear more critical. However, selected cases may still warrant higher L-AMB doses based on individualized risk-benefit assessment.\n\nID: 42478981\nTitle: Thirty Years of Minimally Invasive Colorectal Surgery at the Fundeni Clinical Institute: An Institutional Experience.\nAbstract: Background: Minimally invasive colorectal surgery has evolved considerably in our country over the past three decades, although its early adoption was slow and uneven in many centers. At the Fundeni Clinical Institute, this evolution began in 1995 with the first reported laparoscopic colorectal operation performed in Romania, marking the start of a gradual transition from the open approach to minimally invasive surgery for both colonic and rectal pathology. Methods: We conducted a retrospective institutional review, integrating historical milestones, published experience, and analysis of internal databases. Laparoscopic, robotic-assisted, and transanal techniques were evaluated, with emphasis on oncologic colorectal surgery and the progressive expansion of minimally invasive indications. Results: After an initial period of cautious and limited dissemination, minimally invasive colorectal surgery progressively expanded as surgical expertise and technological resources improved. The adoption of advanced laparoscopic procedures, including the laparoscopic reversal of the Hartmann procedure and various transanal techniques, reflected the extension of minimally invasive colorectal practice beyond selected cases to more complex colorectal surgery. Between 2012 and 2023, 2,447 rectal cancer resections were performed, of which 446 were minimally invasive. After discontinuation of the robotic program, laparoscopic surgery served as the sole minimally invasive approach and was paradoxically associated with a further increase in minimally invasive procedures, despite the absence of robotic surgery, without compromising oncologic or postoperative outcomes. Conclusions: The experience of the Fundeni Clinical Institute illustrates the successful maturation of minimally invasive colorectal surgery from an early pioneering stage to a stable and expanding practice. Despite initial limitations and the discontinuation of the robotic program, laparoscopic surgery became the main driver of minimally invasive procedures, enabling their extension to more complex cases without compromising oncologic or perioperative outcomes. This evolution highlights the institute\u00e2s role in consolidating minimally invasive colorectal surgery as a reliable standard in a high-volume center.\n\nID: 42478051\nTitle: Cell-size heterogeneity acts as a regime-dependent mechanical switch for collective migration.\nAbstract: Cell-size heterogeneity is ubiquitous in epithelial tissues, yet the fundamental physical principles governing its impact on collective migration remain elusive. Here, we show that size heterogeneity acts as a regime-dependent mechanical switch: it enhances collective motility in solid-like tissues while strongly suppressing migration in fluidized ones. This reversal arises from a previously unrecognized energetic hierarchy that governs microscopic topological remodeling. By systematically quantifying the work required for cellular neighbor exchanges, we demonstrate that size diversity reshapes the tissue energy landscape. In heterogeneous tissues, larger cells function as mechanically constrained anchors that elevate local rearrangement barriers, stabilizing the tissue against topological fluctuations. Crucially, these emergent energetic constraints either compete with or reinforce shape-based structural changes depending on the mechanical state, dictating the overall rate of tissue remodeling. Together, our results establish a unified physical framework linking microscale size heterogeneity to the fundamental energetic cost of cell rearrangements, and suggest that cell-size distribution serves as an intrinsic tunable parameter that dictates the epithelial mechanical property and migratory potential across diverse physiological contexts.\n\nID: 42477258\nTitle: Effect on Mortality of Anticoagulant Reversal in Acute Intracranial Hemorrhage: A Systematic Review and Meta-analysis.\nAbstract: Reversal treatment is used to counterbalance effects of oral anticoagulation in intracranial hemorrhages. Despite effects on reducing hematoma expansion, the impact on mortality remains uncertain. Our aim was to assess the effects of reversal treatment on mortality in various forms of oral anticoagulant-associated intracranial hemorrhage. Systematic searches were performed in the electronic databases of PubMed, Embase, Scopus, and Web of Science from database inception to March 2025. We included studies that compared mortality between patients receiving reversal treatment vs. non-reversal in oral-anticoagulant-associated intracranial hemorrhages. Only studies with appropriate statistical controlling for significant confounding variables were included. Data extraction and synthesis was performed according to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) checklist. Data were summarized and pooled effect estimates were presented. Outcome was mortality, and primarily with a follow-up limited to 3\u00a0months. A total of 8217 studies were screened; 8 were ultimately included, all observational, and including 8777 participants with documented reversal treatment. For the overall analysis, when all types of intracranial hemorrhage and all types of anticoagulants were included, reversal was associated with reduced mortality (RR 0.78 (95% CI 0.67-0.91); p\u2009=\u20090.002). This association was also seen in the subgroup analysis of 8639 participants with nontraumatic intracerebral hemorrhage on any oral anticoagulant (RR 0.77 (95% CI 0.64-0.94); p\u2009=\u20090.009), but not among the 3059 participants with intracerebral hemorrhage treated with only direct oral anticoagulants (RR 0.91 (95% CI 0.80-1.03); p\u2009=\u20090.15). Current evidence for reduced mortality following anticoagulant reversal in intracranial hemorrhage is limited and primarily derived from observational studies. Although pooled data suggest a potential treatment benefit across various types of intracranial hemorrhages and anticoagulants, most hemorrhage subtypes remain insufficiently studied. Going forward, there is a critical need for randomized clinical trials and additional well-controlled observational studies to determine which patients truly benefit from reversal treatment.\n\nID: 42477224\nTitle: Anatomic Reversal of Gastric Bypass as a Last Resort for Refractory Complications: A Retrospective Case Series.\nAbstract: Gastric bypass procedures are highly effective for severe obesity management, but a small subset of patients develop devastating complications refractory to medical management. This study evaluates the outcomes of complete reversal to normal anatomy following failed gastric bypass. We conducted a retrospective case series of 13 patients (0.9% of 1,450 bypass patients) who underwent complete laparoscopic reversal to normal anatomy between 2020 and 2024. Indications included severe malnutrition after one-anastomosis gastric bypass (OAGB) (n\u2009=\u20095), intractable marginal ulcers after Roux-en-Y gastric bypass (RYGB) (n\u2009=\u20094), and severe dumping syndrome after RYGB (n\u2009=\u20094). We assessed operative outcomes, symptom resolution, nutritional markers, and weight changes at 1-year follow-up. The cohort was predominantly female (76.9%) with a mean age of 42.1\u2009\u00b1\u20092.2 years. Mean time to reversal was 1.9\u2009\u00b1\u20090.6 years. Mean operative time was 76.0\u2009\u00b1\u20096.2\u00a0min with zero intraoperative complications. All patients (100%) achieved complete resolution of their primary complication. In the malnutrition cohort, serum albumin improved from 2.16\u2009\u00b1\u20090.11\u00a0g/dL to 3.84\u2009\u00b1\u20090.10\u00a0g/dL (p\u2009<\u20090.001), and hemoglobin improved from 9.12\u2009\u00b1\u20090.31\u00a0g/dL to 12.64\u2009\u00b1\u20090.35\u00a0g/dL (p\u2009<\u20090.001). However, mean BMI increased significantly from 23.9\u2009\u00b1\u20091.8\u00a0kg/m\u00b2 to 31.8\u2009\u00b1\u20091.2\u00a0kg/m\u00b2 (p\u2009<\u20090.001), with 84.6% of patients returning to a BMI\u2009>\u200930\u00a0kg/m\u00b2 at one year. Complete reversal to normal anatomy is a safe and highly effective treatment for severe, refractory complications of gastric bypass, providing symptom resolution. However, it is universally associated with significant weight regain, necessitating careful patient selection, preoperative counseling, and aggressive postoperative weight management.\n\nID: 42476247\nTitle: Regulatory interplay of miR-361-5p/TWIST1/SOX4 axis modulating epithelial-mesenchymal transition cascades in metastatic prostate cancer.\nAbstract: Prostate cancer (PCa) progression and metastasis remain significant challenges in clinical oncology. miR-361-5p has been identified to function as an important tumor suppressor in multiple human malignancies. However, the clinical significance and biological role of miR-361-5p in PCa remain unclear. The present study was conducted to investigate the molecular mechanisms in metastatic PCa by using various experimental methods in vitro and in vivo. miR-361-5p was significantly downregulated in PCa cells and tissues. Overexpression of miR-361-5p inhibited proliferation, migration, and invasion in vitro, and suppressed tumor growth and lung metastasis in vivo. Mechanistically, miR-361-5p directly targeted TWIST1, reducing its protein levels and transcriptional activity; restoration of TWIST1 rescued the metastatic phenotype, confirming functional targeting. Importantly, miR-361-5p also regulated SOX4 via TWIST1 and formed a negative feedback loop with SOX4, reinforcing the suppression of metastasis. This TWIST1/SOX4 axis drove a reversal of epithelial-mesenchymal transition, marked by increased E-cadherin and decreased Vimentin and Fibronectin expression. The present study, for the first time, suggests that miR-361-5p functions as a tumor suppressor in PCa by modulating the TWIST1/SOX4 axis and EMT. These insights offer new therapeutic avenues for targeting miRNAs in metastatic PCa.\n\nID: 42476174\nTitle: Spin Josephson diode effect induced by higher-harmonic spin Josephson currents in a diffusive Josephson junction.\nAbstract: We theoretically investigate the spin Josephson diode effect (SJDE) in a diffusive Josephson junction with a Rashba metal layer under a ferromagnetic exchange field. Within the quasiclassical Green's function framework, we derive analytical expressions for the first- and second-harmonic spin Josephson currents. The interplay between Rashba spin-orbit interaction and the exchange field breaks inversion and time-reversal symmetries, generating additional cosine terms in the spin current-phase relations and a finite $\\varphi_{0}$ phase shift.
This phase shift induces an intrinsic asymmetry between forward and backward spin currents, leading to the SJDE without an external magnetic field. Numerical results show that the efficiency decreases with increasing metal thickness due to suppression of the second-harmonic component, while its dependence on spin-orbit interaction strength reflects competing effects between phase shift enhancement and harmonic suppression. These findings demonstrate that the interplay between harmonic components provides a mechanism for nonreciprocal spin transport without requiring suppression of spin-singlet correlations.\n\nID: 42475992\nTitle: Krueppel-like factors transcriptionally regulate idiopathic pulmonary fibrosis.\nAbstract: Idiopathic pulmonary fibrosis (IPF) is a devastating interstitial lung disease (ILD) characterized by excessive inflammation and deposition of extracellular matrix (ECM) in the pulmonary niche, ultimately leading to decline of pulmonary function. Even though there are three food and drug administration (FDA) approved drugs for treatment of IPF, these drugs are ineffective against reversal of the disease but rather can only reduce the progression of the disease. As a result, the median survival rate for IPF is extremely low and new therapeutic strategies are urgently needed. Krueppel-like factors (KLFs) are zinc finger containing transcription factors that control the outcome associated with various types of diseases, given their critical role in cellular differentiation and proliferation. The role of KLFs is very cell specific and as a result it finely balances the inflammation associated with various diseases. Even though different members of the KLF family have been reported to have a role in IPF, this review summarizes the role of KLFs in regulation of inflammation associated with idiopathic pulmonary fibrosis.\n\nID: 42475972\nTitle: TPGS incorporated solanesol-paclitaxel prodrug nanoparticles for synergic therapy of cancer.\nAbstract: Paclitaxel (PTX) chemotherapy is severely limited by poor aqueous solubility, off-target toxicity, and P-glycoprotein-mediated multidrug resistance (MDR). Herein, we report a redox-responsive prodrug nanosystem, SOL-SS-PTX, constructed by conjugating PTX to the bioactive natural polyisoprenoid solanesol (SOL) via a disulfide bond. Unlike conventional polymer- or lipid-based carriers, SOL simultaneously serves as the hydrophobic self-assembly driver and a pharmacologically active co-agent, enabling synergistic antitumor activity. The prodrug spontaneously self-assembles into uniform nanoparticles with an ultra-high drug loading of approximately 50% (w/w). D-\u03b1-Tocopheryl polyethylene glycol succinate (TPGS) is further incorporated to enhance stability and reverse MDR via P-gp inhibition. In a reductive tumor-mimetic environment, cumulative PTX release exceeded 80% within 48\u202fh, while less than 10% PTX leakage occurred physiological conditions. In vitro, SOL-SS-PTX/50%TPGS exhibited potent cytotoxicity against both sensitive (A549, HepG-2) and resistant (A549/MDR) cells, achieving a reversal resistance index (RRI) higher than that of the ester-linked control (2.75 fold). In H22 xenograft-bearing mice, the nanoformulation achieved a 69.7% tumor growth inhibition rate with no observable organ toxicity. This work establishes SOL-SS-PTX as a high-drug-loading, stimulus-responsive prodrug platform that synergistically integrates natural product pharmacology, redox-triggered release, and MDR reversal for drug-resistant cancer therapy.\n\nID: 42475908\nTitle: Irreversible mechanical weakening of amyloid-\u03b2 K16 mutants via electrostatic torque.\nAbstract: Amyloid-beta (A\u03b2) fibrils act as the structural core of Alzheimer's disease pathology and maintain exceptional mechanical stability through dense \u03b2-sheet networks. However, the molecular mechanisms through which external physical stimuli disrupt these robust scaffolds remain poorly understood, particularly the residue-specific responses. Here, we systematically evaluated the structural collapse and mechanical attenuation of A\u03b2 fibrils and their K16 mutants, including the charge-reversal K16D and bulky K16W, under a 1.0\u00a0V/nm electric field (EF) using molecular dynamics (MD) simulations. We demonstrated that this external stimulus persistently disrupts the \u03b2-sheet hydrogen-bond network within the simulated recovery window and leads to a drastic reduction in Young's modulus driven by dipole-field misalignment. Notably, this response was highly mutation dependent since the K16D mutant exhibited severe orientation-dependent collapse due to an amplified electrostatic torque, whereas K16W maintained its structural resistance via enhanced steric packing. Furthermore, EF induced a sustained increase in the solvent-accessible surface area (SASA). These findings suggest that external EF can serve as a potent physical modulator to destabilize pathogenic amyloid aggregates, potentially overcoming the physical barrier of dense plaques, enhancing the penetration and efficacy of therapeutic agents.\n\nID: 42475546\nTitle: Sustainable and Highly Selective Depression of Serpentine in Pyrite Separation Enabled by Phosphorylated Nanocellulose.\nAbstract: Hetero-aggregation between serpentine and sulfide minerals represents a persistent challenge in the efficient recovery of valuable metals from complex ores, while most existing depressants suffer from limited selectivity, insufficient suppression efficiency, or environmental and toxicity concerns, restricting their application in sustainable mineral processing. Herein, we report for the first time the use of a phosphorylated nanocellulose biopolymer as a highly selective and environmentally benign depressant to overcome serpentine-induced interference in sulfide flotation, and elucidate the selective depression and interfacial mechanism. Phosphorylated cellulose nanofibers (P-CNF) and phosphorylated cellulose nanocrystals (P-CNC) were synthesized by introducing phosphate functional groups, resulting in a marked enhancement in pyrite flotation performance, with recoveries exceeding 88.0% and reaching 89.6% for P-CNF. The exceptional separation efficiency arises from the highly selective adsorption of phosphorylated cellulose on the serpentine MgOH plane, with a surface coverage of 96.32% on serpentine compared to only 0.28% on the pyrite surface. This pronounced selectivity induced a reversal of the serpentine surface charge, thereby transforming pyrite-serpentine interactions from electrostatic attraction to strong repulsion. Force-resolved atomic force microscopy measurements provided direct nanoscale evidence for this transition, revealing a dramatic reduction in adhesion forces from \u223c9.81 mN m-1 to \u223c1.25 mN m-1 (P-CNC) and \u223c0.10 mN m-1 (P-CNF). Moreover, phosphorylated nanocellulose promoted the flocculation of fine serpentine particles via polymer-bridging effects, leading to the enlarged aggregates and effective suppression of mechanical entrainment. This work establishes phosphorylated nanocellulose as a novel green depressant platform and provides molecular insights into interfacial interactions governing complex mineral separation, thereby enabling the rational design of sustainable reagents and advancing resource-efficient environmentally interfacial responsible mineral processing.\n\nID: 42474296\nTitle: Islet-Targeted ZnT8 Antibodies Protect Pancreatic \u03b2-Cells From Inflammatory Stress.\nAbstract: Inflammatory stress increases endoplasmic reticulum protein-folding burden in \u03b2-cells and amplifies immunogenicity through HLA-I hyperexpression, yet targeted strategies to restore \u03b2-cell proteostasis are lacking. We demonstrate that an islet-specific, cell surface-directed antibody is internalized and functions as a zinc transporter 8-selective chaperone, enhancing endoplasmic reticulum folding capacity, attenuating HLA-I hyperexpression, and robustly inducing programmed death-ligand 1. Identification of programmed death-ligand 1 as a direct pharmacodynamic marker of zinc transporter 8-chaperoning links on-target engagement to reinforcement of local immune checkpoint signaling. Humanized Fc-silent Isle43 shows durable pancreatic retention, dose-dependent reversal of new-onset type 1 diabetes in nonobese diabetic mice, sustained remission after treatment cessation, and protection of human islet graft function in\u00a0vivo. This islet-targeted strategy preserved \u03b2-cell function in inflammatory mouse models and human islet grafts, supporting an islet-targeted therapeutic approach for inflammatory \u03b2-cell failure.\n\nID: 42474185\nTitle: PKC inhibitors reveal PKC isoforms involved in HIV latency reversal and immunomodulation.\nAbstract: The reservoir of persistently latently infected cells is a major barrier to a cure for HIV infection. Protein kinase C (PKC) modulators can reverse HIV latency and could thus be useful \"Kick\" components in \"Kick and Kill\" approaches to a cure. However, PKC modulators also affect immune cell function, potentially limiting their clinical safety and utility. Here, using PKC isoform inhibitors in models of HIV latency and HIV-negative mononuclear cells, we determined the PKC isoforms involved in PKC modulator-mediated HIV latency reversal and immunomodulation (CD69 and CD4 expression, and inflammatory cytokine production). We found that inhibition of PKC \u03b1, \u03b2, \u03b3, \u03b4, or \u03b8 limited PKC-mediated HIV latency reversal to varying degrees. We also found that combinatorial PKC isoform inhibition significantly limited robust PKC modulator-mediated immune cell surface expression of CD69 and cytokine production. None of the pharmacologic PKC inhibitors affected PKC modulator-mediated downmodulation of T-cell surface CD4 expression. These results provide important insight into the isoforms involved in the various PKC modulator-mediated activities, including HIV latency reversal. Design of next-generation PKC modulators that are more selective for PKC \u03b1, \u03b2, and \u03b8 may allow for the partial functional decoupling of HIV latency reversal from immunomodulatory effects, and lead to safer and more effective PKC modulator-based latency-reversing regimens.IMPORTANCEHIV persists in long-lived, latently infected cellular reservoirs, which prevents the cure of the infection using currently available antiretroviral therapy alone. The \"Kick and Kill\" strategy proposes the use of latency-reversing agents (LRAs) to induce viral reactivation leading to reservoir elimination. Protein kinase C (PKC) modulators are one of the most potent classes of LRAs and operate through the activation of several PKC isoforms. Here, we demonstrate the contribution of various PKC isoforms to PKC modulator-mediated HIV latency reversal and immunomodulation. We identified PKC \u03b1, \u03b2, and \u03b8 as the isoforms important for latency reversal, while other isoforms, especially broad PKC isoform activation, had greater relative effects on immune cell activation and cytokine release. Together, these results define the pathways required for PKC-mediated HIV latency reversal and other important immunomodulatory effects and will thus inform the development of next-generation isoform-selective PKC modulator LRAs.\n\nID: 42474054\nTitle: Voltage-tunable nonequilibrium dispersion interactions.\nAbstract: We develop a nonequilibrium Green's function theory for dispersion interactions between two nanostructures, each an open quantum system driven into a nonequilibrium steady state by an applied bias voltage. Starting from the two-particle nonequilibrium Green's function, we derive a general expression for the interaction energy in terms of the polarization propagators of the individual systems. The interaction energy admits a physically transparent decomposition into charge noise and charge dissipation contributions, providing a fluctuation-dissipation interpretation that generalizes the equilibrium London picture. Model calculations for coupled molecular junctions demonstrate that the applied voltage can enhance the attractive dispersion interaction by nearly an order of magnitude relative to equilibrium. In thermal equilibrium, the dispersion interaction is universally attractive, irrespective of the specific form of the nanostructure Hamiltonians or their coupling to reservoirs. Out of equilibrium, we introduce a generalized Kubo-Martin-Schwinger ratio that parameterizes the departure from detailed balance. We show that, in contrast to equilibrium, nonequilibrium conditions can lead to a repulsive dispersion interaction. Finally, we discuss the conditions under which population inversion in the electronic leads can drive a sign\u00a0reversal of the dispersion interaction.\n\nID: 42472995\nTitle: Directional propagation of interface modes in topological acoustic metamaterials via spin-momentum locking.\nAbstract: Topological acoustics enables backscattering-immune wave transport along domain interfaces, whose directionality can be deterministically controlled through spin-momentum locking of the excitation source. In this work, we computationally demonstrate a monolithic two-dimensional Ge2Sb2Te5 (GST) phononic crystal plate in which hexagonally patterned crystalline inclusions are embedded within an amorphous GST host, where the impedance contrast between the two phases opens a topological bandgap. Here we show that the overlap integral between an external excitation source and the Bloch eigenstates governs directional selectivity. The source position and phase determine which topological pseudospin channel is excited, enabling deterministic routing through spin-momentum locking. Our system exploits [Formula: see text] symmetry, which supports degenerate [Formula: see text]-type and [Formula: see text]-type orbital modes at the [Formula: see text] point serving as pseudospin degrees of freedom. When a single harmonic force is applied, it projects onto both pseudospin channels, yielding bidirectional propagation. By contrast, a quadrature phased force pair on neighboring inclusions generates a rotating displacement field whose coupling to one pseudospin state identically vanishes, locking propagation to a single direction. Swapping the force positions reverses the routing direction, and this reversal is spatially invariant across the interface, providing evidence of spin-momentum locking. By varying only the source configuration, the same interface operates as a bidirectional waveguide, unidirectional isolator, or selective router. These results demonstrate how spin-momentum locking can serve as an efficient mechanism for directional selectivity of topological interface states in monolithic structures, with relevance to on-chip acoustic signal routing and frequency-selective wave filtering.\n\nID: 42472143\nTitle: Assessment of Changes in Diaphragm Thickness to Predict Extubation Outcomes After Prolonged Upper Abdominal Surgery.\nAbstract: Prolonged upper abdominal surgery causes postoperative pulmonary complications, such as weaning failure. The diaphragmatic thickening fraction (DTF) is regarded as the surrogate of the breathing workload and correlates well with diaphragm strength. Compromised diaphragm function negatively influences ventilation, leading to difficulty in weaning from a mechanical ventilator. The objectives of the study were to estimate the changes in diaphragm thickness and the best cutoff value that will predict extubation failure at the end of prolonged upper abdominal elective surgery. In this prospective observational study, 120 patients (aged 18-70 years) of either sex and with American Society of Anesthesiologists physical status I or II, scheduled to undergo upper abdominal surgery lasting four hours or more, were included. Patients taking more than 30 minutes to extubate from the time of administration of the reversal agent were categorized as failure to extubate. The DTF was assessed via ultrasonography.\u00a0 Results: Twenty-five (20.83%) patients had failed extubation. Sex (P = 0.001) and pre-extubation DTF (P < 0.001) were identified as significant variables distinguishing patients who were successfully extubated from those who failed extubation. Multivariate logistic analysis showed that female sex (odds ratio (OR) = 0.233; P\u00a0= 0.010) and pre-extubation DTF (OR = 1.071; P\u00a0= 0.001) were significantly associated with successful extubation. A pre-extubation DTF cutoff of >22.63% predicted successful extubation with a sensitivity of 88.04%, a specificity of 56.0%, and an area under the receiver operating characteristic curve (AUC-ROC) of 0.752 Conclusions: Diaphragmatic dysfunction is common after prolonged upper abdominal surgery, and DTF may help identify patients at risk of extubation failure.\n\nID: 42471923\nTitle: Postoperative Respiratory Depression and Other Postoperative Pulmonary Complications in Veterinary Practice: A Narrative Review.\nAbstract: Postoperative respiratory depression (PORD) and other postoperative pulmonary complications (PPCs) represent significant contributors to perioperative morbidity and mortality in companion animal practice. The Confidential Enquiry into Perioperative Small Animal Fatalities (CEPSAF) established that cardiovascular and respiratory causes account for approximately 74% and 72% of perioperative deaths in dogs and cats, respectively, with 47% of canine and 61% of feline anesthetic-related deaths occurring in the postoperative period. PORD arises from a convergence of opioid-induced respiratory depression (OIRD), residual inhalant anesthetic effects, other drug-induced effects (e.g., neuromuscular blockade), and patient-specific vulnerabilities. PPCs encompass a broad spectrum of conditions, including atelectasis, aspiration pneumonia, pneumonia, hypoventilation, acute respiratory distress syndrome (ARDS), and respiratory arrest, with laparotomy studies reporting a PPC incidence of 22% in dogs. This narrative review synthesizes current evidence on the pathophysiology, risk factors, diagnostic approaches, prevention strategies, and treatment of PORD and PPCs in veterinary practice, incorporating insights from both veterinary-specific and translational human anesthesia literature, while explicitly identifying areas where veterinary-specific evidence remains limited. The importance of continuous monitoring during the postanesthetic period, multimodal analgesia to reduce opioid exposure, protective lung ventilation strategies, and early intervention is highlighted as a key strategy to improve outcomes, together with the unmet need for reversal-independent (\"agnostic\") respiratory stimulants capable of countering PORD irrespective of the causative agent.\n\nID: 42471920\nTitle: CPT2 as a Convergent Node Linking Age-Associated Neuronal H3K27me3 Remodeling to Nicotinamide Mononucleotide (NMN)-Induced Expression Rescue in Metabolic Tissues.\nAbstract: Age-related decline in mitochondrial function and disruption of epigenetic regulation are two closely connected features of biological aging. In neurons, age-associated remodeling of repressive H3K27me3 chromatin may constrain genes needed for metabolic, synaptic, and stress-adaptive maintenance. In parallel, nicotinamide mononucleotide (NMN), an NAD+ precursor, has been reported to mitigate age-associated physiological and transcriptional changes in peripheral metabolic tissues. However, direct links between neuronal epigenetic aging programs and NMN-responsive transcriptional rescue remain unclear. Here, we performed a secondary integrative analysis of two public datasets: GSE190102, focused on age-associated neuronal H3K27me3 targets mapped through an activity-by-contact-style region-gene framework, and GSE85718, a long-term NMN transcriptomic dataset from skeletal muscle, liver, and white adipose tissue in mice. The analysis identified 23 genes shared between 21,155 aging H3K27me3-associated targets and 35 robust NMN-rescue genes. Because the aging target set was extremely broad, gene-level overlap was not statistically persuasive, and pathway-level convergence was absent. Under repressive-mark direction logic, 14 of the 23 shared genes were concordant, meaning that the NMN expression effect opposed the expected consequence of age-associated H3K27me3 remodeling. Objectives were to quantify overlap between neuronal age-associated H3K27me3 targets and robust NMN-responsive genes in peripheral metabolic tissues, classify shared genes by directional concordance under repressive chromatin logic, and identify high-priority mechanistic candidates. The analysis supports limited global convergence and nominates CPT2 as the leading convergent node for targeted validation. CPT2 emerged as the leading candidate. It showed age-associated H3K27me3 gain, a large K27me3 log-fold change of +3.504, NMN-induced expression increase in old animals, a positive NMN interaction coefficient of +0.201, and membership in the mitochondrial fatty-acid oxidation pathway. Within the downstream shared-gene mitochondrial analysis, CPT2 was the only mitochondrial-core gene, with nominal enrichment only. These findings do not support a broad reversal of neuronal epigenetic aging by NMN. Instead, they identify CPT2 as a biologically coherent and experimentally tractable candidate linking age-related repressive chromatin remodeling to NMN-responsive mitochondrial metabolism.\n\nID: 42471500\nTitle: Achieving monosex male tilapia: a critical review of hormonal, biodegradable and genome editing strategies.\nAbstract: Nile tilapia culture faces significant challenges due to early maturation and uncontrolled reproduction, leading to stunted growth and overpopulation. The primary solution is producing all-male populations or sterile fish. While the synthetic androgen 17\u03b1-methyltestosterone has been the industry standard for hormonal sex reversal for decades, environmental and consumer safety concerns, including potential carcinogenicity, have driven the search for sustainable alternatives. This critical review examines the full spectrum of approaches for producing monosex male tilapia, encompassing traditional methods (manual sexing, hybridization), hormonal treatments (synthetic steroids, aromatase inhibitors), biodegradable options (plant extracts like\u00a0Tribulus terrestris\u00a0and\u00a0Basella alba, animal by-products such as cattle and carp testes), and novel genetic strategies (YY male technology, genome editing). We highlight innovative biodegradable programs and discuss how nanoparticle-mediated drug delivery can enhance therapeutic efficacy. Furthermore, we explore how genome editing technologies like CRISPR-Cas9 offer groundbreaking potential for understanding and controlling sex determination systems. Finally, we critically evaluate these methods based on effectiveness, cost, scalability, and sustainability to guide future research and the development of more environmentally responsible practices for the tilapia aquaculture industry.\n\nID: 42470641\nTitle: Protocol for HIV-1 latency reversal using engineered bacteriophage T4 particles.\nAbstract: A major barrier to curing HIV-1 is the latent viral reservoir in resting CD4+ T cells. Here, we present a protocol for preparing CD4-DARPin (designed ankyrin repeat protein)-T4 nanoparticles and their application to HIV-1 latency reversal in a model of HIV-1 latency. We describe steps for producing T4 capsid nanoparticles in E. coli and their decoration with the CD4-targeting DARPin ligand fused to the T4 outer capsid protein Hoc. We then detail procedures for assessing proviral reactivation using fluorescence readouts. For complete details on the use and execution of this protocol, please refer to Batra et al.1.\n\nID: 42470310\nTitle: Engineering Function-Reversal Sacrificial Sites for Selective Volatile Aromatic Hydrocarbons Detection in Complex Environments.\nAbstract: Accurately monitoring carcinogenic volatile aromatic hydrocarbons (BTXs) is crucial for assessing air-qualities and danger-classes in specific occasions, However, it remains challenging to conduct highly selective identification of them in complex environments. Here, we have developed a gas-shunting strategy by installing function-reversal ZnO materials into Ir-WO3 supports to diminish interference-gas responses and guide special aromatic hydrocarbons sensing. We find that ZnO materials can serve as reactively sacrificial sites for small-molecule H2S and CO and induce main aromatic hydrocarbons reactants into Ir-WO3 supports. This gas-shunting route guarantees highly-selective aromatic hydrocarbons sensing even in dual/ternary gas mixtures. Through integrating functional-opposite sensors into a system, the final sensing arrays achieve 100% classification accuracy for 10 single gases and 75 multi-compose gases with low training costs. In addition, we also show an autonomic \"cruise-detection\" system by equipping sensor arrays into robotic dog to accurately identify complex gases. Our findings emphasize sensors designs with selective features and may broaden integrated sensing-system analysis in complex environment.\n\nID: 42469846\nTitle: Metabolic reprogramming via SIRT2-deficient microglial large extracellular vesicles ameliorates alzheimer's pathology.\nAbstract: Current therapies for Alzheimer's disease (AD) offer only symptomatic relief, highlighting the urgent need for disease-modifying approaches capable of halting or reversing neurodegeneration. Extracellular vesicles (EVs) have attracted growing interest as therapeutic vehicles owing to their inherent capacity to bypass the blood-brain barrier and deliver complex biological cargo to the central nervous system. Here, we examined whether large EVs (LEVs) derived from microglia with stable Sirtuin-2 knockdown (SIRT2-KD) confer the neuroprotective effects associated with SIRT2 inhibition. LEVs harvested from SIRT2-KD microglia were administered intranasally to APP/PS1 mice. We assessed microglial uptake of LEVs, along with subsequent changes in cellular metabolism, migration toward amyloid-beta (A\u03b2) plaques, phagocytic activity, and downstream pathological and behavioral outcomes. Proteomic and acetylomic profiling were employed to characterize the molecular cargo of LEVs-SIRT2-KD. LEVs-SIRT2-KD were readily internalized by microglia in vivo following intranasal delivery. Uptake of these vesicles markedly enhanced microglial bioenergetics, driving coordinated upregulation of both oxidative phosphorylation and glycolysis. This metabolic shift was accompanied by improved microglial recruitment to A\u03b2 plaques and increased phagocytic clearance. Consequently, treated mice showed reduced A\u03b2 plaque deposition, restored synaptic integrity, and reversal of cognitive deficits. Proteomic and acetylomic analyses revealed that LEVs-SIRT2-KD are selectively enriched in proteins and acetylation modifications linked to energy metabolism and phagocytic function, offering a mechanistic basis for the observed metabolic reprogramming. Together, these results identify LEVs as a critical vesicle subtype mediating the effects of SIRT2 knockdown and support a cell-free therapeutic strategy for AD centered on EVs-driven metabolic reprogramming of microglia.\n\nID: 42469074\nTitle: Heparin Dose-Response Curve for Heparin Dose Determination During Cardiopulmonary Bypass for Pediatric Cardiac Surgery: A Prospective Randomized Controlled Study.\nAbstract: To determine whether individualized heparin dosing guided by a heparin dose-response (HDR) curve is noninferior to conventional weight-based dosing in achieving target activated clotting time (ACT) of \u2265480 seconds before cardiopulmonary bypass (CPB) and to compare total heparin and protamine requirements, postoperative blood loss, and transfusion needs in children younger than 14 years undergoing cardiac surgery with cardiopulmonary bypass support. Single-center, prospective, double-blinded, randomized controlled trial. Cardiothoracic operating theaters and intensive care unit of a tertiary care hospital in India. Pediatric (<14 years) patients undergoing elective cardiac surgery with CPB support. The HDR group received an initial test dose of 100 IU/kg of heparin, and an individualized ACT dose-response curve was constructed to determine the dose required to target an ACT of 480 seconds. Controls received standard 400 IU/kg of heparin. Protamine was given post-CPB per protocol in both groups. In this noninferiority trial, HDR-guided anticoagulation was assessed against conventional weight-based dosing for first-pass attainment of ACT \u2265480 seconds before CPB. Target ACT was achieved in 72.2% (26/36) of HDR patients versus 83.3% (30/36) of controls (p = 0.396). Although HDR was associated with lower heparin exposure (260 v 420 IU/kg; p < 0.001) and protamine use (4.1 v 4.8 mg/kg; p = 0.002), as well as reduced 24-hour blood loss (5.2 v 6.5 mL/kg; p = 0.03) and packed red blood cell transfusion (6.8 v 8.2 mL/kg; p = 0.04), it did not demonstrate superior first-attempt ACT attainment. HDR-guided heparinization reduced heparin and protamine exposure and was associated with less bleeding and transfusion, but it did not improve first-pass ACT attainment. Because ACT is an imperfect surrogate for anticoagulant adequacy in children on CPB, these findings should be interpreted as ACT-guided dosing data rather than proof of equivalent anticoagulation. Larger multicenter studies with mechanistic and clinical endpoints are needed to confirm these results.\n\nID: 42468942\nTitle: The Use of Dexmedetomidine Hydrochloride as a Single Pharmaceutical and in Combination with Ketamine for Sedation of Cynomolgus Macaques (Macaca fascicularis).\nAbstract: Sedation in nonhuman primates (NHPs) is commonly achieved with ketamine (KET), which provides short-term (less than 30 minutes) sedation but is associated with undesirable side effects such as twitching, increased jaw tone, and hypersalivation. This study investigates the use of dexmedetomidine (DEX) in cynomolgus macaques (Macaca fascicularis) as a potential alternative or adjunct sedative. Four experiments were conducted to determine: (1) the safety and efficacy of DEX as a sole sedative; (2) optimal dose combinations of DEX and KET; (3) a comparison of DEX/KET sedation outcomes to historical KET-only sedation data; and (4) a comparison of the sedation duration of DEX/KET combinations to KET alone. First, we evaluated escalating doses of DEX (0.02-4.04 mg/kg), and in 11 of 14 attempts, animals remained rousable and maintained posture for up to 90 minutes. Then, we used a fixed DEX dose (0.75 mg/kg) combined with escalating KET doses (1.0-2.252 mg/kg) to reduce overall KET exposure and successfully achieved 90 minutes of sedation. We then compared DEX/KET sedation outcomes to prior KET-only sedation records, revealing fewer instances of emesis, less food waste, and improved repairing success with DEX/KET. Finally, KET alone (10 mg/kg) or a DEX/KET combination (0.75 mg/kg DEX and 2.25 mg/kg KET) was evaluated for routine colony management procedures without atipamezole (ATI) reversal. The DEX/KET group exhibited significantly longer sedation durations with reduced hypersalivation and vomiting compared with the KET-only group. These experiments demonstrated that DEX alone was insufficient for sedation in macaques at the tested doses and had no adverse outcomes at significantly higher doses than previously reported. We recommend a DEX/KET dose of 0.75 mg/kg DEX and 2.25 mg/kg KET to provide sedation and reduce side effects (vomiting, food waste).\n\nID: 42468784\nTitle: E-TAP: A Novel Echocardiographic Risk Stratification Score in the Assessment of Cardiac Tamponade and Decision Making for Pericardiocentesis.\nAbstract: Echocardiographic findings suggesting hemodynamic compromise can precede clinical deterioration in cardiac tamponade. We aim to validate echocardiographic predictors for tamponade and construct a simple imaging-based risk stratification model to guide prompt management plans. We retrospectively studied consecutive patients who presented with at least moderate pericardial effusion. Patients with atrial fibrillation, greater than moderate pulmonary hypertension, or mechanical ventilation were excluded. Patients were identified as having cardiac tamponade if the intrapericardial pressure was \u22657 mmHg. The following echocardiographic parameters, each assigned equal weight, were evaluated to create the E-TAP (Echocardiography in Tamponade Assessment to recommend Pericardiocentesis) score: (1) right atrial late diastolic collapse, (2) right ventricular early diastolic collapse, (3) discordant left and right ventricular measurement variation indicating ventricular interdependence, (4) mitral valve inflow E velocity variation >30%, (5) tricuspid valve inflow E velocity variation >60%, (6) left ventricular outflow velocity variation >20%, (7) inferior vena cava plethora, (8) reversal of diastolic flows of the hepatic vein in expiration, and (9) large pericardial effusion. Of the 254 patients, 134 had tamponade, with a mean E-TAP score of 6.0 +/- 1.8, compared to 3.0 +/-1.7 in those without tamponade (p<0.001). Adjusted logistic regression analyses showed that IVC plethora, TV inflow variation >60%, and LVOT flow variation >20% were independently associated with tamponade. An E-TAP score \u2265 5 best identified patients with tamponade with 80% specificity and 81% sensitivity. The novel E-TAP score was strongly associated with cardiac tamponade and may facilitate timely decision making for pericardiocentesis.\n\nID: 42468510\nTitle: To reverse or not to reverse: Direct oral anticoagulants in mild traumatic brain injury.\nAbstract: The growing usage of direct oral anticoagulants (DOACs) has brought into question the need for pharmacologic reversal in patients who develop traumatic brain injuries (TBIs). While there are specific benefits in reversal for TBI patients on warfarin, the impact has not been clearly shown in DOAC populations. This study evaluated radiographic and clinical outcomes among patients with isolated mild TBIs to determine whether DOAC usage or its reversal confers measurable differences in early outcomes. We conducted a retrospective review of adults (18 to 99\u00a0y) with isolated mild TBI (Glasgow Coma Scale: 13 to 15) after ground-level falls at a Level I trauma center from 2016 to 2024. The primary outcome was radiographic hemorrhage progression, defined as >2-mm increase in hemorrhage or need for >2 head computed tomographies within 24 hours. Secondary outcomes included Glasgow Coma Scale decline, intensive care unit length of stay, neurosurgical intervention, thromboembolic events, disposition, and inpatient mortality. Multivariable logistic regression and propensity score matching were used to evaluate associations between DOAC usage, reversal therapy, and outcomes. Among 273 patients, 96 (35%) were taking a DOAC, and of these, 41 received four-factor prothrombin complex concentrate and 18 received andexanet alfa. DOAC patients demonstrated similar rates of radiographic progression, intensive care unit length of stay, and discharge disposition compared with non-DOAC patients. In multivariate analysis, DOAC usage was not associated with increased radiographic progression, measured by subdural hemorrhage growth (47.5% vs. 44.8%; p = 0.70) or increased need for >2 computed tomography scans (49.1% vs. 48.9%, p = 1.00). Among DOAC users, reversal was also not associated with improved radiographic progression or secondary outcomes. No significant outcome differences were observed between reversal with four-factor prothrombin complex concentrate and andexanet alfa. In isolated mild TBI after ground-level falls, DOAC usage was not associated with worsened clinical outcomes or increased radiographic progression. Pharmacologic reversal offered no measurable benefit. These findings support selective reversal in stable mild TBI.

Lotus leaf (Nelumbo nucifera Gaertn.) is a traditional edible and medicinal plant, and its calcined derivative, Heyehui (Hyh), has been documented for anti-obesity effects since the Ming Dynasty. However, the chemical composition and molecular mechanisms of Hyh against diet-induced obesity (DIO) remain largely uncharacterized. This study aimed to identify the chemical constituents and quantify the key bioactive components of Hyh, validate its anti-obesity efficacy in a DIO mouse model, and elucidate the underlying molecular mechanisms, thereby providing modern scientific evidence for its traditional application in anti-obesity therapy. Hyh composition was profiled by UPLC-MS, UV-Vis, and HPLC. DIO mice received Hyh intervention for 8 weeks; body weight, obesity indices, and serum glucose-lipid parameters were then assessed alongside histopathological examinations. The LEP/AMPK/ACC pathway and lipid synthesis factors were quantified by ELISA, immunofluorescence, qRT-PCR, and Western blot. Active components targeting LEPR were screened via molecular docking and DeepDrugDiscovery. Nuciferine and quercetin were further evaluated in 3T3-L1 adipocytes with shLEPR knockdown and Compound C validation. Intestinal barrier integrity and gut microbiota were analyzed by 16S rRNA sequencing. Fecal SCFAs were quantified by GC. Hyh was rich in alkaloids and flavonoids, with high nuciferine and quercetin contents. Hyh-treated DIO mice exhibited significantly reduced body weight, Lee's index, abdominal circumference, and body fat, accompanied by improved serum glucose-lipid profiles. Histologically, adipocyte shrinkage, decreased hepatic lipid deposition, and downregulated lipid synthesis factors were observed in adipose and liver tissues. Hyh activated the LEP/AMPK/ACC axis, promoting fatty acid \u03b2-oxidation; nuciferine and quercetin were identified as the key mediators, as evidenced by shLEPR knockdown and Compound C reversal. Hyh also upregulated occludin, claudin1, and ZO-1 in the duodenum, restored intestinal barrier integrity, suppressed CD36 and FATP4, increased gut microbial diversity, elevated fecal SCFA levels, and enriched genera such as Rikenella, which negatively correlated with obesity indicators. Hyh, with nuciferine and quercetin as its principal active constituents, ameliorates obesity and metabolic disorders in DIO mice through a multi-target mechanism that encompasses suppression of lipid synthesis, activation of fatty acid \u03b2-oxidation, repair of the intestinal barrier, remodeling of the gut microbiota, and elevation of short-chain fatty acid levels. The present study characterized the chemical composition of Hyh and elucidated its anti-obesity mechanisms, thereby providing a modern scientific basis for its traditional application. Although its clinical efficacy remains to be validated in future trials, Hyh demonstrates considerable potential as a natural anti-obesity agent.\n\nID: 42468300\nTitle: Transcranial photobiomodulation ameliorates hypobaric hypoxia-induced spatial cognitive dysfunction by enhancing synaptic plasticity.\nAbstract: High-altitude environments are characterized by hypobaric hypoxia (HH), which disrupts cerebral homeostasis and precipitates cognitive dysfunction. Transcranial photobiomodulation (tPBM), a non-invasive neuromodulatory intervention for neuroprotection and functional restoration, has emerged as a promising therapeutic strategy. This study aimed to evaluate the therapeutic efficacy of tPBM against HH-induced spatial cognitive dysfunction and elucidate the underlying neurobiological mechanisms. Spatial learning and memory were assessed using the Barnes maze. Regional cerebral blood flow dynamics were evaluated using diffuse reflectance spectroscopy and laser Doppler flowmetry. Additionally, histological examination, transcriptome sequencing, and molecular biology analyses, were integrated to delineate the biological mechanisms and identify candidate signaling pathways and molecular targets. Barnes maze performance demonstrated that tPBM significantly ameliorated HH-induced deficits in spatial learning and memory. Mechanistically, tPBM modulated hemodynamic responses and enhanced cerebral oxygen-binding efficiency within the lateral parietal association cortex (LPtA). Furthermore, tPBM improved mitochondrial function by elevating cytochrome c oxidase activity and promoting ATP synthesis. Concurrently, tPBM suppressed hypoxia-inducible factor-1\u03b1 overexpression and microglial reactivity, reduced oxidative stress biomarkers, and augmented antioxidant enzyme activity. These molecular alterations were associated with preservation of synaptic structure, including reversal of dendritic spine loss. Transcriptome analysis further indicated that tPBM may preserves synaptic plasticity homeostasis by modulating the PI3K-Akt, cAMP-PKA, and calcium signaling pathways, with Adora2a identified as a potential therapeutic target. Collectively, these findings demonstrate that tPBM exerts neuroprotective effects against HH-induced spatial cognitive dysfunction by improving cerebral hemodynamics, enhancing mitochondrial function, attenuating neuroinflammation and oxidative stress, and preserving structural synaptic plasticity.\n\nID: 42467767\nTitle: Picosecond switching of magnetic tunnel junctions by spin-orbit torque.\nAbstract: Ultrafast switching of magnetic tunnel junctions (MTJs) is essential for future high-bandwidth memory and in-memory computing. However, state-of-the-art electrical switching of MTJs remains constrained to hundreds of picoseconds, leaving a substantial gap between memory and processors. Here, we experimentally demonstrate field-free switching of three-terminal MTJs using picosecond electrical pulses driven by spin-orbit torque (SOT), surpassing the speed limit by an order of magnitude. We further use voltage-gated (VG) effect to probe SOT switching mechanisms over wide pulse-width ranges and identify a nonmonotonic VG-SOT efficiency. While the efficiency is pronounced under long-pulse excitation, it diminishes in the subnanosecond regime but reemerges as the pulse width scales down to 13.2 ps, yielding an energy consumption about 30 fJ per bit. Micromagnetic analysis reveals that, from dc to picosecond timescale, the dominant magnetization switching dynamics evolve from thermally activated reversal to incoherent precession to coherent precession. These results establish picosecond VG-SOT as a pathway toward ultrafast and energy-efficient memory and logic.\n\nID: 42467421\nTitle: Emergency department management of postthrombolysis intracranial hemorrhage.\nAbstract: Intracranial hemorrhage following intravenous thrombolytic therapy most commonly occurs within 12 hours of administration. Because many patients remain in the emergency department during this period, a structured, time-sensitive approach to recognition and management is critical. This review summarizes current recommendations for the diagnostic workup, use of reversal agents, and escalation of care for postthrombolysis intracranial hemorrhage, with particular attention to guidelines addressing stroke and neurocritical care management. Contraindications to intravenous thrombolysis and risk factors for postthrombolysis intracranial hemorrhage are also discussed.\n\nID: 42466305\nTitle: Non-uniform cycling of Li metal batteries: Impacts to life and performance.\nAbstract: Advances in cell design have improved lithium-metal battery (LMB) cycle life, but few studies assess performance under discharge profiles representative of real-world use. These profiles, which are often overlooked due to the complexity and risk of misinterpretation, can hinder accurate analysis or even prevent publication. Realistic discharge profiles include high currents during acceleration, current reversal during regenerative braking, and low steady currents at cruising speed. This work examines LMB performance using localized high-concentration electrolytes (LHCEs) under dynamic cycling, focusing on acceleration and regeneration pulses. These profiles bridge practical usage and controlled conditions for reproducible trends. Single-layer pouch cells are tested with LHCEs of lithium bis(fluorosulfonyl)imide (LiFSI), 1,2-dimethoxyethane (DME), with either 1,1,2,2-tetrafluoroethyl 2,2,3,3-tetrafluoropropyl ether (TTE) or bis(2,2,2-trifluoroethyl) ether (BTFE). The inclusion of pulsing dramatically alters the failure of the cells and increases cell-to-cell variability. Increasing the ionic conductivity and electrolyte volume decreases cell-to-cell performance variability. Cells with LHCE-BTFE exhibit more consistent cycling capacity behavior and fewer performance metric fluctuations, such as a rise of polarization or peak cell pressure, under non-uniform cycling compared to LHCE-TTE. These findings suggest that rapid transition from benchtop testing to real-world deployment for LMBs will require the inclusion of more realistic cycling conditions.\n\nID: 42465729\nTitle: Impaired consolidation of spatial memory during sleep in patients with leucine-rich glioma-inactivated 1-associated limbic encephalitis.\nAbstract: Sleep promotes the systems consolidation of hippocampus (HC)-dependent spatial memories by reprocessing of previously encoded hippocampal representations. Hippocampal reprocessing involves pattern separation and pattern completion as central hippocampal functions performed by the dentate gyrus (DG) and cornu ammonis region 3 (CA3), respectively. The leucine-rich, glioma inactivated 1 (LGI1)-associated limbic encephalitis (LE) is an autoimmune brain disorder particularly affecting the DG and CA3 regions, thereby impairing hippocampal function. We studied 15 LGI1 patients (and matched healthy controls) to examine hippocampal contributions to the sleep-associated consolidation of spatial memory. Spatial memory was assessed using the virtual Morris water maze (VWM) during learning before nocturnal sleep. Spatial retrieval of target locations (as indicated by dwell time in target area) was tested in the next morning, with separate trials testing pattern separation and pattern completion functions, as well as place memory precision and reversal learning capabilities. Leucine-rich, glioma inactivated 1-associated limbic encephalitis (LGI1-LE) patients were able to learn and retrieve spatial locations, albeit to a lesser extent than controls. Recall of place memories was decreased in LGI1-LE patients in comparison with learning performance before sleep and with healthy controls, especially in trials assessing pattern separation. Moreover, at recall, LGI1 patients showed a less flexible adaptation to the reversal learning task, in comparison with the controls. Sleep quality, macro-sleep architecture and EEG slow oscillations (SOs) and spindles were comparable in both groups. However, in LGI1-LE patients, phase-amplitude coupling of SO-spindle events appeared diminished although the group difference did not remain significant after correction for multiple comparisons. In addition, a negative correlation between spindle density and retrieval of target locations was observed. Magnetic resonance imaging confirmed smaller volumes of the HC and its subfields (subiculum, CA1, CA3, DG) in the patients. Divergent structure-function relationships emerged between patients with LGI1-associated encephalitis and healthy controls: In patients, larger volumes of DG and CA3 were associated with weaker sleep-dependent consolidation but greater stability under cue deprivation. In controls, larger hippocampal, CA1, and subicular volumes correlated with better memory retrieval and reversal learning performance. Our results show an impaired sleep-associated consolidation of spatial memory in LGI1-LE patients highlighting the involvement of DG and CA3 areas in sleep-associated spatial memory formation and cognitive flexibility.\n\nID: 42465492\nTitle: E2F1 Drives Endothelial Arterial Programming in Pulmonary Arterial Hypertension.\nAbstract: Pulmonary arterial hypertension (PAH) is driven by maladaptive endothelial remodeling, but the transcriptional regulators that couple proliferative stress to arterialized endothelial states remain incompletely defined. E2F transcription factor 1 (E2F1) is classically viewed as a cell-cycle regulator; whether E2F1 functions as a disease-driving node that promotes endothelial arterial programming in PAH remains unknown. We integrated human PAH lung transcriptomic analyses, deconvolution-based endothelial-state scoring, and complementary mouse and rat PH models with bulk RNA-seq, single-cell RNA-seq, pseudotime analysis, and CellChat inference. E2F1 function was tested using adenoviral E2F1 overexpression, pharmacological pan-E2F inhibition with HLM006474, and genetic E2f1 loss on a tamoxifen-inducible endothelial Egln1 -deletion background. In PAH lungs, E2F1 was increased and arterial endothelial cell (AEC) fraction and expanded arterial program scores were elevated. Similarly, Egln1 Tie2Cre lungs showed increased E2F1, induction of arterial remodeling genes, and activation of an E2F target program. Genetic loss of E2f1 reduced right ventricle systolic pressure, right ventricle hypertrophy, vascular remodeling, and distal muscularization in Egln1 -driven PH mice model. Bulk RNA-seq showed suppression of E2F, mitotic, epithelial mesenchymal transition, and extracellular matrix-remodeling programs. Single-cell RNA-seq showed reduced AEC accumulation, normalized CAP1/CAP2 distribution, and reduced progression along the CAP1-AEC trajectory. CellChat analysis identified loss of an arterial communication hub, including reduced ECM, VEGF, and Notch signaling when E2F1 is loss. Conversely, E2F1 overexpression in human lung microvascular ECs increased proliferation, activated E2F/cell-cycle and Notch/arterial programs. Pharmacological inhibition of E2F via HLM006474 suppressed endothelial proliferation and attenuated Egln1 -driven and MCT-induced PH, including reversal of established MCT-PH. E2F1 acts as a disease-relevant transcriptional factor linking endothelial cell-cycle activation to arterial programming, matrix and angiogenic communication programs, and pulmonary vascular remodeling. Genetic or pharmacological E2F inhibition mitigates experimental PH, supporting E2F1 as a therapeutic target in PAH. 1. This study identifies E2F1 as a previously unrecognized driver of PAH rather than only a downstream marker of cell-cycle activation.2. Genetic loss of E2f1 rescues hemodynamic and structural features of Egln1-driven PAH, and pharmacological E2F inhibition attenuates both Egln1-driven and monocrotaline-induced PH.3. Mechanistically, E2F1 links endothelial proliferation to Notch-associated arterial programming, AEC accumulation, and CAP1-to-iAEC-to-AEC trajectory progression. 1. E2F1 defines a tractable transcriptional node that integrates proliferative stress with arterial endothelial reprogramming, a core pathological feature of PAH vascular remodeling.2. Pan-E2F small-molecule inhibitors, several of which are in development for oncology, may be repurposable for PAH if E2F1-dependent endothelial arterial-programming signatures identify responsive disease states.3. Plasma- or tissue-based readouts of E2F1 activity may identify PAH patients most likely to benefit from E2F-directed therapy.\n\nID: 42467639\nTitle: N-acetyl-L-leucine normalizes Transcription Factor EB activity by stereospecific bidirectional modulation in a HeLa cell model of Niemann-Pick disease type C.\nAbstract: Levacetylleucine (Aqneursa\u2122), an acetylated derivative and pro-drug of L-leucine, is the only FDA-approved monotherapy for Niemann-Pick disease type C (NPC). Its acetyl group enables transport via monocarboxylate transporters, supporting blood-brain barrier penetration and efficient cellular uptake. Inside cells, levacetylleucine is metabolised by acylases, generating elevated levels of L-leucine that enhance mitochondrial bioenergetics and is thought to ameliorate lysosomal dysfunction indirectly. Here, we describe a direct effect of levacetylleucine on lysosomal regulation through modulation of TFEB, the master transcription factor for lysosomal and autophagy genes. Levacetylleucine rapidly alters TFEB translocation between the cytoplasm and the nucleus in a biphasic, homeostasis-restoring manner. In wild-type HeLa cells, levacetylleucine promotes TFEB activation and nuclear localisation. However, in NPC1 disease models, where we show that TFEB is over-activated and enriched in the nucleus due to lysosomal stress, levacetylleucine reduces nuclear TFEB and restores a more normal cytoplasmic-to-nuclear balance. These effects occur at clinically relevant concentrations associated with lysosomal storage reduction. The effects of the drug are stereospecific: while the L-enantiomer is active, the D-enantiomer and racemate show no effect, revealing the antagonistic properties of the D-enantiomer. This bidirectional normalisation of TFEB activity highlights a direct mechanism through which levacetylleucine modulates lysosomal and autophagic pathways in the HeLa cell model, giving mechanistic insight into its therapeutic potential in NPC, and also across diverse neurological and neurodevelopmental disorders.\n\nID: 42451740\nTitle: Lysosomes in Ferroptosis: Regulatory Mechanisms and Molecular Targets.\nAbstract: Ferroptosis is a regulated form of cell death characterized by iron-dependent lipid peroxidation and membrane damage, with broad relevance to human disease. Accumulating evidence suggests that ferroptosis is governed by coordinated organelle-level regulation, among which lysosomes have emerged as central hubs. By controlling endolysosomal iron processing, transport, and degradation pathways, lysosomes shape the intracellular distribution and reactivity of iron, thereby modulating iron-driven lipid peroxidation. The acidic, iron-rich microenvironment and limited local antioxidant capacity render lysosomal membranes highly susceptible to oxidative injury, positioning lysosomes as initiation and amplification sites of lipid peroxidation. Meanwhile, lysosome-dependent selective autophagy pathways actively remodel iron homeostasis, lipid metabolism, and cellular antioxidant defenses, thereby dynamically modulating ferroptotic sensitivity. Mitochondria-lysosome crosstalk further redistributes iron, reactive oxygen species, and lipid substrates, linking lysosomal activity to interorganelle control of ferroptosis. Lysosomal stress-responsive signaling also coordinates metabolic adaptation and redox control. This review summarizes and integrates current evidence on lysosome-centered mechanisms that organize iron metabolism, lipid peroxidation, selective autophagy, organelle crosstalk, and stress-responsive signaling during ferroptosis, and further discusses their disease-specific roles, therapeutic potential, and translational challenges.\n\nID: 42442910\nTitle: Genetic and epigenetic complexity of Parkinson's disease: From dopamine pathways to estrogen interplay.\nAbstract: Parkinson's disease (PD) is a progressive neurodegenerative disorder characterized by selective loss of nigrostriatal dopaminergic neurons and extensive circuit disruption, clinically presenting with motor deficits and many non-motor symptoms. Pathologically, PD is linked to the aggregation of \u03b1-synuclein, mitochondrial and lysosomal stress, and chronic neuroinflammation. This chapter integrates the genetic and epigenetic framework of Parkinson's disease, encompassing rare monogenic factors such as SNCA, LRRK2, GBA1, PINK1, and PRKN that converge on proteostasis disruption, compromised mitophagy, and lysosomal dysfunction, alongside polygenic susceptibility that may be exacerbated by environmental influences. Epigenetic dysregulation further influences susceptibility and disease progression: altered DNA methylation and hydroxymethylation at PD-relevant loci such as PARK7 and NR4A2, maladaptive histone regulation (including increased HDAC2/3 activity), and non-coding RNA networks (miR-7, HOTAIR, circSNCA) that modulate \u03b1-synuclein expression, inflammatory pathways, mitochondrial dynamics, and clearance mechanisms. Sex dimorphism is emphasized as a biologically significant modifier, with males exhibiting a higher incidence and accelerated progression in numerous cohorts, whereas estrogen-associated signaling may provide neuroprotection through increased dopamine biosynthesis, enhanced antioxidant capacity, and inhibition of microglial activation-effects that may diminish post-menopause. This chapter integrates recent advancements by linking mechanistic insights to translational potential, focusing on epigenetic biomarkers and disease-modifying techniques designed to restore lysosomal function, rectify dopamine processing, and strategically exploit hormone pathways.\n\nID: 42372357\nTitle: Raloxifene and tamoxifen reshape the immunometabolic phenotype of TLRs-activated macrophages through AEBS inhibition and lysosomal stress.\nAbstract: Macrophages are key effectors of innate immune responses and infection control, relying on Toll-like receptors (TLRs) to sense pathogens and adopt immunometabolic anti-infective phenotypes. Raloxifene (RAL) and tamoxifen (TAM) are selective estrogen receptor modulators (SERMs) known to reprogram macrophage inflammatory responses via estrogen receptor-independent mechanisms, including NRF2 activation. Although drug repurposing approaches have highlighted anti-infective properties of these compounds, supporting host-directed mechanisms, the upstream targets and immune consequences of RAL and TAM in macrophages remain undefined. Here, we investigated the biological relevance and molecular determinants of SERM-mediated immune activity in TLR-activated macrophages. Our results show that RAL and TAM modulate inflammatory cytokine expression induced by TLR7/8, TLR4, and TLR2 stimulation. Specifically, these SERMs enhance IL 1\u03b2 maturation, despite reducing proIl1b mRNA levels, and increase TNF \u03b1 production, while restraining IL 6 expression. Notably, IL 6 repression is more pronounced with RAL and correlates with sustained NRF2 pathway engagement, suggesting a drug-specific immunoregulatory profile. Furthermore, RAL and TAM influence cytokine regulation through cholesterol-pathway remodeling consistent with AEBS inhibition, which was associated with PI3K-NRF2 activation and NRF2-related immunometabolic adaptation. In parallel, RAL and TAM promote lysosomal perturbations, leading to the regulation of proIl1b and Tnfa mRNA levels and to cathepsin B-associated caspase-1 activation and IL1\u03b2 production. Cathepsin B inhibition further enhances NRF2-target gene responses, suggesting functional crosstalk between lysosomal and NRF2-associated pathways. Overall, these findings indicate that RAL and TAM elicit an integrated immunometabolic reshaping of macrophage inflammatory phenotypes, through cholesterol-pathway remodeling and lysosomal stress, supporting SERMs as host-directed chemotherapeutic agents.\n\nID: 42359813\nTitle: HIV-1 gp120-induced lysosomal stress responses are controlled by TRPML1 redox sensors.\nAbstract: Increased lysosomal stress responses (LSR) are commonly implicated in the pathogenesis of neurodegenerative disorders including HIV-1-associated neurocognitive disorders (HAND). The HIV-1 envelope glycoprotein gp120 causes LSR, increases levels of ferrous iron (Fe2+) in the cytosol and in mitochondria, disrupts the reactive species interactome (RSI), and increases neural cell death. Using SH-SY5Y human neuroblastoma and U87MG human astrocytoma cells treated with gp120 and pharmacological modulators, we evaluated redox signaling and LSR by redox-sensitive fluorescent probes, spinning-disk confocal microscopy, flow cytometry, Western blotting, and immunostaining. Here, we report that TRPML1, an endolysosome redox-sensitive cation channel, is mechanistically involved in gp120-induced neurotoxicity. TRPML1 was activated by gp120-induced increases in cytosolic reactive oxygen species (ROS) and resulted in release of Fe2+ from endolysosomes in levels sufficient to increase cytosolic levels of Fe2+ and ROS as well as decrease levels of hydrogen sulfide (H2S). Reduced glutathione normally buffers intracellular Fe2+, but gp120 decreased endolysosome glutathione levels and disrupted this regulatory control mechanism thereby promoting TRPML1-mediated Fe2+ efflux from endolysosomes. TRPML1 redox activation led to changes to the RSI in endolysosomes including increased ROS, lipid peroxidation, nitric oxide, and sulfane sulfur as well as decreased H2S. These changes were accompanied by increased cysteine oxidation of luminal proteins and endolysosome deacidification. Pharmacological inhibition of TRPML1 or knocking down expression levels of TRPML prevented these effects. Our findings suggest that TRPML1 redox activation controls gp120-induced endolysosome dysfunction and iron/redox imbalance, and further implicates TRPML1 in the pathogenesis of HAND.\n\nID: 42340476\nTitle: An Engineered Multifunctional Fusion Protein Targeting A\u03b2 Oligomers, Microglia and Autophagy Ameliorates Cognitive Deficits and Amyloid Pathology in Alzheimer's Disease Mice.\nAbstract: In Alzheimer's disease (AD), Amyloid-\u03b2 (A\u03b2) oligomers function as key neurotoxic agents that underpin the disease's progression. A diverse array of therapeutic entities, including peptides, single-chain variable fragments (scFvs), and small molecules, have demonstrated the ability to interact with A\u03b2 oligomers, thereby suppressing their aggregation and associated neurotoxicity. Despite these advances, such agents frequently struggle to promote the phagocytosis and subsequent breakdown of aggregated A\u03b2 by microglia. Moreover, the dense accumulation of A\u03b2 oligomers may resist enzymatic hydrolysis within the acidic lysosomal lumen, contributing to lysosomal stress and dysfunction. To overcome these problems, we engineered a multifunctional fusion protein, p62-LIR-W20-Tuftsin (W20-LT), consisting of an oligomer-specific scFv, a microglia-targeting Tuftsin peptide, and a p62-LIR peptide to activate autophagy. In vitro assays demonstrated that W20-LT significantly outperformed the parental W20 by promoting the rapid microglial uptake of A\u03b2 oligomers and enhancing their intracellular clearance through an autophagy-associated pathway. In APPswe/PS1dE9 (APP/PS1) mice, a low-dose regimen (0.5\u00a0\u00b5g, every 3 days) of W20-LT, but not W20, significantly ameliorated cognitive deficits and reduced amyloid pathology. Mechanistically, W20-LT was associated with enhanced autophagy-lysosomal pathway activity, as indicated by increased LC3B-II and reduced p62 levels, together with downregulated CatD and LAMP1 levels, thereby mitigating neuroinflammation. In summary, our findings suggest that W20-LT represents a promising proof-of-concept therapeutic strategy that combines scFv-based A\u03b2 oligomer recognition with enhanced autophagy-associated clearance, thereby mitigating AD pathology.\n\nID: 42284733\nTitle: VPS13C-mediated endoplasmic reticulum-lysosome tethering in neuronal stress responses.\nAbstract: Organelle contact sites are increasingly recognized as regulatory interfaces that coordinate lipid transfer, ion signaling, and metabolic adaptation. In neurons, communication among the endoplasmic reticulum (ER), lysosomes, and mitochondria is essential for cellular homeostasis. Recent studies have identified vacuolar protein sorting 13 homolog C (VPS13C), a lipid transport protein, as a key mediator of ER-lysosome tethering and as an important component of the response to lysosomal stress. Structural analyses show that VPS13 family proteins form elongated lipid transport channels that are proposed to facilitate phospholipid transfer between adjacent membranes. Following lysosomal damage, VPS13C is recruited to ER-lysosome contact interfaces, where it forms tethering bridges that may support membrane repair by enabling high-capacity lipid transfer from the ER to lysosomal membranes. Beyond membrane repair, these contact interfaces may also participate in broader organelle communication networks. ER-lysosome contacts can occur in proximity to ER-mitochondria junctions, potentially forming multi organelle signaling hubs that coordinate lipid redistribution, calcium signaling, and mitochondrial adaptation. These signals may influence downstream responses, including activation of TFEB and TFE3, which regulate lysosomal biogenesis and autophagy. Disruption of this contact site network has emerged as a potential contributor to Parkinson's disease. Loss of VPS13C function is associated with altered lysosomal homeostasis and intersects with pathogenic pathways involving \u03b1-synuclein aggregation, PINK1/Parkin-mediated mitophagy, and LRRK2 signaling. This review presents a framework in which ER-lysosome tethering is considered part of a staged cellular damage response linking membrane repair, metabolic coordination, and transcriptional adaptation.\n\nID: 42274750\nTitle: From lipid overload to autophagy collapse: how lipid dysregulation drives chronic inflammation and metabolic disease.\nAbstract: Autophagy is a central homeostatic mechanism that preserves intracellular quality control by clearing damaged organelles, aggregated proteins, and excess lipids. Increasing evidence indicates that the lipid-autophagy axis is a critical determinant of chronic inflammatory and metabolic disease. Cholesterol-rich and oxidatively modified lipoproteins, including very-low-density lipoprotein (VLDL), low-density lipoprotein (LDL), oxidized LDL, and lipoprotein(a), can impose lysosomal stress, disturb autophagosome maturation, and amplify oxidative and inflammatory signaling, whereas high-density lipoprotein-mediated cholesterol efflux supports cellular lipid clearance and autophagic competence. When chronic lipid overload exceeds lysosomal and autophagic capacity, cells transition from adaptive lipophagy to impaired autophagic flux, leading to lipid-droplet accumulation, mitochondrial dysfunction, inflammasome activation, and sustained cytokine production. This review synthesizes mechanistic insights linking lipid dysregulation and autophagy failure across atherosclerosis, metabolic dysfunction-associated steatotic liver disease/metabolic dysfunction-associated steatohepatitis (MASLD/MASH), and neurocognitive disorders. We further discuss how defective autophagy impairs efferocytosis, phagosome maturation, and inflammasome restraint, thereby contributing to unresolved inflammation and inflammatory cell-death signaling. Translationally, we outline therapeutic strategies that combine metabolic unloading, lipid-lowering interventions, autophagy-lysosome modulation, and flux-based biomarker approaches. Lipid-induced autophagic flux failure provides a unifying framework for understanding how metabolic stress evolves into chronic inflammation and organ dysfunction and identifies actionable targets for precision therapeutic intervention.\n\nID: 42251851\nTitle: Mestranol induces a reversible lysosomal storage-like state in zebrafish microglia.\nAbstract: Environmental estrogenic compounds are increasingly recognized as neurotoxicants, yet their effects on microglia intracellular homeostasis in vivo remain poorly understood. Using zebrafish larvae as a live imaging model, we identify the synthetic estrogen mestranol as a potent inducer of a reversible lysosomal storage-like state in microglia. Mestranol exposure causes pronounced microglia hypertrophy and reduces neutral red staining, without affecting microglia number or neuronal apoptosis. Functional analyses show that mestranol-treated microglia retain phagocytic capacity toward apoptotic neurons and bacterial particles but fail to efficiently digest internalized cargo, leading to intracellular accumulation. Although acidic vesicles and protease\u2011associated compartments expand and disperse throughout the cytoplasm, lysosomal degradative efficiency is markedly impaired, suggesting that cargo digestion is compromised despite the formation of acidic phagolysosomal compartments. Transcriptomic profiling of flow\u2011sorted macrophage/microglia populations reveals coordinated down\u2011regulation of lysosomal-phagosomal and immune gene networks, including MIT/TFE family transcription factors (TFEB/TFEC) and immune master regulators such as SPI1, IRFs, BATF, MAFB, and RUNX3. Overexpression of TFEC partially rescues both estradiol and mestranol-induced microglia hypertrophy and neutral red loss, although the rescue is only partial, indicating a more complex mechanism involving additional TFEC-independent pathways. Notably, microglia lysosomal dysfunction and hypertrophy are reversible upon drug withdrawal. Together, our findings demonstrate that mestranol induces an acquired and regulatable lysosomal stress state in microglia, characterized by immune transcriptional suppression and impaired intracellular digestion. This work establishes a live, reversible in vivo model for studying estrogen\u2011associated neuroimmunotoxicity and microglia vulnerability to lysosomal stress.\n\nID: 42195297\nTitle: Transcriptomic Profiling of Monozygotic Twins with Type 1 Gaucher Disease.\nAbstract: Background: Gaucher disease (GD) arises from pathogenic variants in the GBA1 gene and is known for its wide range of clinical presentations-a variability that genotype alone cannot adequately account for. Objective: This study aimed to explore transcriptomic factors that might help explain why two genetically identical twins with type 1 GD developed noticeably different clinical outcomes. Methods: We isolated peripheral blood mononuclear cells from both twins and two age-matched controls, then differentiated them into macrophages in vitro before conducting RNA sequencing. Gene expression differences were analyzed using established bioinformatics pipelines, and a subset of genes were subsequently assessed by quantitative real-time PCR (qRT-PCR) to confirm the sequencing findings. Results: Both twins shared a GD-associated transcriptional signature broadly reflecting immune activation and lysosomal stress. Interestingly, the twin who experienced systemic complications had a relative enrichment of interferon-responsive transcripts, while the less severely affected twin showed more pronounced suppression of small nucleolar RNA clusters. That said, neither difference held up after correcting for multiple comparisons, so these patterns are best viewed as exploratory trends rather than definitive findings. The qRT-PCR results lend partial support to this picture: stress- and immune-related genes (DDIT4, RPH3A, SAMSN1) trended toward higher expression in patients versus controls, and interferon-stimulated genes (ISG15, RSAD2, IFI44L) were more elevated in M2 than in M1. Conclusions: Taken together, these findings suggest that factors beyond genetics-whether epigenetic, environmental, or otherwise-may play a meaningful role in shaping how GD manifests differently even between individuals with identical DNA. Although the data are preliminary, they point to transcriptomic profiling, paired with targeted validation, as a useful starting point for building hypotheses about why this disease looks so different from one patient to the next, even when the underlying mutation is the same.\n\nID: 42168651\nTitle: Foamy microglia link oxylipins to disease progression in multiple sclerosis.\nAbstract: Multiple sclerosis (MS) is a chronic neuroinflammatory disease in which demyelinating white matter lesions accumulate and expand, driving irreversible disability. Here we identify a distinct population of foamy GPNMB+ microglia/macrophages associated with lesion expansion in secondary progressive MS. Using integrated lipidomic, transcriptomic, proteomic, chemical proteomic and histological analyses of human postmortem MS lesions, we show that lesions containing foamy microglia/macrophages exhibit disrupted lipid metabolism, lysosomal stress and markers associated with heightened phagocytosis and antigen presentation without classical pro-inflammatory signatures. These lesions are enriched for oxylipins, bismonoacylglycerolphosphates and cholesterol esters, and are associated with increased B cell infiltration and IgG1. Monoacylglycerol lipase (MAGL), a lipid-metabolizing enzyme enriched in lesions with foamy microglia/macrophages, emerged as a potential therapeutic target. Inhibition of MAGL promoted lesion recovery and reduced microgliosis in a mouse model of demyelination. Finally, oxylipins in cerebrospinal fluid correlate with the proportion of foamy lesions, suggesting potential biomarkers for progression. Our findings implicate disturbed lipid metabolism in chronic MS pathology and suggest that foamy microglia/macrophages are an interesting cell type to target for progressive disease.\n\nID: 42159746\nTitle: Acute cell\u2011death and lysosomal stress responses to nicotine and cigarette smoke extract in human mesenchymal stromal cells.\nAbstract: Mesenchymal stromal cells (MSCs) are essential for connective tissue repair, and impaired healing is well documented in tobacco users. MSCs are one plausible target for these adverse effects, but the underlying cellular mechanisms of high localized nicotine exposure remain poorly understood. This study investigated how short-term nicotine and cigarette smoke extract (CSE) exposure affect human MSC function, viability, and inflammatory signaling in vitro. MSCs isolated from bone marrow were exposed to CSE containing 4-40\u00a0\u00b5M nicotine or to 100\u00a0\u00b5M-10\u00a0mM pure nicotine. CSE produced markedly stronger cytotoxicity than nicotine, reducing proliferation and rapidly inducing necrotic cell death at 20-40\u00a0\u00b5M nicotine equivalents. Pure nicotine elicited a biphasic response: concentrations below 5\u00a0mM slightly increased proliferation, while 5\u00a0mM caused apoptotic cell death with prominent lysosomal vacuolization, and 10\u00a0mM shifted cell death toward necrosis. Sublethal exposures that generated pre-apoptotic cells were associated with significant IL8 induction and MMP2 activation, whereas IL6 remained largely unchanged. Nicotine induced lysosomal disruption suggests broader impacts on MSC homeostasis beyond viability, potentially influencing lineage commitment. These findings elucidate short-term effects of nicotine and CSE; high-dose nicotine and CSE are toxic to MSCs, while the lower doses perturb the inflammatory signaling and lysosomal function. Such alterations may compromise tissue regeneration, wound healing, and periodontal stability in users of potent localized nicotine delivery products.\n\nID: 42120505\nTitle: Lysosomal vulnerability as a therapeutic target in thyroid cancer using fucoidan nanoparticles.\nAbstract: Thyroid cancer represents the ninth most common malignancy worldwide, and a subset of cases exhibits aggressive behaviour with limited therapeutic options. Fucoidan, a sulphated polysaccharide, has demonstrated anticancer activity with an undefined mechanism. Here, we investigated the biological effects of fucoidan (FU) and fucoidan nanoaggregates (NFU) in both thyroid cancer (SW1736) and non-tumorigenic thyroid cells (Nthy-ori 3.1). NFU showed a mean diameter of ~\u2009187\u00a0nm, a low polydispersity (~\u20090.2) and a negative Zeta potential. NFU significantly reduced SW1736 cell viability, reaching\u2009~\u200960% inhibition at 0.01\u00a0mg/mL and ~\u200980% at 0.1\u00a0mg/mL after 72\u00a0h, while sparing non-tumorigenic cells. Mechanistically, NFU induced marked lysosomal enlargement selectively in tumor cells and localized predominantly within LAMP-1-positive compartments. Consistently, tumor cells showed constitutive Cathepsin D maturation and enhanced sensitivity to NFU-induced lysosomal perturbation. Collectively, these findings identify lysosomes as a primary intracellular target of fucoidan-based nanosystems and reveal a tumor-selective vulnerability to NFU-mediated lysosomal stress. This study provides the first quantitative evidence of lysosomal targeting by fucoidan nanoparticles in thyroid cancer cells and supports NFU as a promising lysosome-directed nanotherapeutic strategy for aggressive thyroid malignancies.\n\nID: 42096896\nTitle: A mycobacterial Sec61 inhibitor disrupts lysosome function by blocking Vacuolar-ATPase biosynthesis.\nAbstract: Mycolactone is the virulence toxin of Mycobacterium ulcerans, causative agent of Buruli ulcer. Mycolactone inhibits the Sec61-dependent co-translational translocation of signal peptide-bearing secreted and membrane proteins into the endoplasmic reticulum. Sec61 inhibition leads to accumulation of mislocalised proteins in the cytosol and initially triggers an integrated stress response-dependent activation of autophagy that contributes to cell survival. Here we show sustained exposure to mycolactone blocks late-stage autophagy and induces nuclear translocation of the lysosomal stress marker TFEB. This follows loss of ATP6AP1 and ATP6AP2, Sec61-substrates required for assembly of the Vacuolar-ATPase, leading to reduced lysosomal biogenesis and acidification. These effects are reduced in cells expressing a mycolactone-resistant Sec61\u03b1 mutant and phenocopied by other Sec61 inhibitors. Loss of lysosomal function compromises the cell's capacity to withstand the proteostatic stress caused by Sec61 inhibition and could impair the ability of phagocytes to combat infection with M. ulcerans and contribute to the tissue necrosis in Buruli ulcer. Furthermore, since Sec61 inhibition is being pursued as a therapeutic target in several diseases, potential drugs should be screened against this activity to avoid unwanted side-effects.\n\nID: 42041586\nTitle: Microphthalmia/Transcription Factor E (MiT/TFE) Pathways in Pulmonary Diseases: Current Evidence and Emerging Mechanisms.\nAbstract: The MiT/TFE family transcription factors play a critical role in lysosomal biogenesis, autophagy, mitochondrial turnover and lipid catabolism by regulating the Coordinated Lysosomal Expression and Regulation (CLEAR)gene network. The dysregulation of MiT/TFE activity has been implicated in the onset and progression of cancer and neurodegeneration, but its functions in association with pulmonary diseases remain poorly understood. In this review, we systematically summarize the findings from human pulmonary diseases and associated genetic disorders, such as asthma, cancer, Birt-Hogg-Dube (BHD) syndrome, and lung injury models that implicate MiT/TFE dysregulation in pathogenic progression. We also discussed MiT/TFE regulation and signaling through pathways involving mTORC1, AMPK, and lysosomal stress in different cellular contexts. Finally, we discussed significant mechanistic gaps, such as the absence of in vivo models targeting the combined activity of TFEB and TFE3 in disease progression and prevention. In conclusion, these insights seek to offer a comprehensive framework for understanding MiT/TFE signaling in human lung diseases and could present a promising opportunity for directing future mechanistic and translational research.\n\nID: 41906739\nTitle: Dual pathways of TFEB activation under lysosomal stress: ATG conjugation-dependent and -independent modes.\nAbstract: TFEB (transcription factor EB) regulates the expression of autophagy and lysosomal genes, is activated by various cellular stresses, and plays a key role in maintaining cellular homeostasis. Recent work demonstrates that TFEB is activated during lysosomal damage through two distinct mechanisms: ATG conjugation-dependent and -independent. TFEB activation proceeds sequentially through two modes. In the early ATG conjugation-independent mode (Mode I), APEX1 interacts with TFEB in the nucleus, maintaining its transcriptional activity and protein stability. In the later ATG conjugation-dependent mode (Mode II), CCT7 and TRIP6 translocate to lysosomes and interact with TFEB, modulating its phosphorylation and nuclear localization. Moreover, TFEB regulation induced by other cellular stresses-such as oxidative stress, proteasome inhibition, mitochondrial damage, and DNA damage-also involves either Mode I or Mode II. Our findings provide new insights into a unified understanding of TFEB regulation under diverse cellular stress conditions.\n\nID: 41867743\nTitle: HIV-1 gp120-induced lysosomal stress responses are controlled by TRPML1 redox sensors.\nAbstract: Increased lysosomal stress responses (LSR) are commonly implicated in the pathogenesis of neurodegenerative disorders including HIV-1-associated neurocognitive disorders (HAND). The HIV-1 envelope glycoprotein gp120 causes LSR, increases levels of ferrous iron (Fe2+) in the cytosol and in mitochondria, disrupts the reactive species interactome (RSI), and increases neural cell death. Here, we report that TRPML1, an endolysosome redox-sensitive cation channel, is mechanistically involved in gp120-induced neurotoxicity. TRPML1 was activated by gp120-induced increases in cytosolic reactive oxygen species (ROS) and resulted in release of Fe2+ from endolysosomes in levels sufficient to increase cytosolic levels of Fe2+ and ROS as well as decrease levels of hydrogen sulfide (H2S). Reduced glutathione normally buffers intracellular Fe2+, but gp120 decreased endolysosome glutathione levels and disrupted this regulatory control mechanism thereby promoting TRPML1-mediated Fe2+ efflux from endolysosomes. TRPML1 redox activation led to changes to the RSI in endolysosomes including increased ROS, lipid peroxidation, nitric oxide, and sulfane sulfur as well as decreased H2S. These changes were accompanied by increased cysteine oxidation of luminal proteins and endolysosome deacidification. Pharmacological inhibition of TRPML1 or knocking down expression levels of TRPML prevented these effects. Thus, our findings suggest that TRPML1 redox activation controls gp120-induced endolysosome dysfunction and iron/redox imbalance, and further implicates TRPML1 in the pathogenesis of HAND.\n\nID: 41846978\nTitle: Vps35 p. D620N causes Lrrk2 kinase hyperactivity, chronic microglial activation and inflammation.\nAbstract: Pathogenic variants in leucine-rich repeat kinase 2 (LRRK2), vacuolar protein sorting 35 (VPS35), and RAB32 cause dominantly inherited parkinsonism, indistinguishable from idiopathic late-onset Parkinson's disease (PD). All three causes constitutively activate LRRK2 kinase activity to augment immune responses, enhancing immunity to fight pathogens, but similar mechanisms in the brain increase the vulnerability of dopaminergic neurons to degeneration. Although VPS35 p.D620N possess the highest constitutive increase in LRRK2 kinase activity among known variants in LRRK2 or RAB32, its effects on the immune system remain poorly understood. LRRK2 and Rab32 are highly expressed in myeloid cells including microglia; thus we examined the transcriptomic and functional consequences of Vps35 p.D620N in knock-in mice (VKI). Microglia were isolated from brains of six-month-old VKI mice and were analyzed via single-cell RNA sequencing. Differential gene expression highlighted pathways involved in antimicrobial humoral immune response, lysosomal stress sensing, and phagocytosis. Notably, genes of S100 family proteins, along with lipocalin 2 (Lcn2), were significantly upregulated, and those measures were complimented by immunohistochemistry and quantitative PCR. In contrast, pathways involved in synaptic transmission, neuronal development, and homeostatic immune signaling were downregulated. Peripheral stimulation with lipopolysaccharide amplified microglial activation and phagocytic markers in wildtype mice, and VKI mice also display enhanced morphological activation and increased synaptic engulfment. Collectively, Vps35 p.D620N drives a chronic pro-inflammatory microglial phenotype characterized by heightened innate immune signaling, lysosomal stress, and enhanced phagocytic activity. VKI microglia are sensitized to peripheral immune challenges and may promote synaptic remodeling and neurodegenerative vulnerability in PD. These results provide mechanistic insight into how retromer dysfunction and LRRK2 kinase hyperactivity intersect with microglial biology to influence PD pathogenesis.\n\nID: 41654644\nTitle: Tributyltin induces conjugation of ATG8s to single membranes via the V-ATPase-ATG16L1 axis, leading to transcription factor EB activation in human cell lines.\nAbstract: Tributyltin (TBT) is an environmental contaminant that induces diverse toxic effects in mammals, but the cellular mechanisms underlying adaptation to TBT stress remain poorly understood. Conjugation of ATG8s to single membranes (CASM) is a noncanonical LC3\u2011lipidation pathway activated by various stressors, distinct from canonical autophagy. We previously showed that TBT reduces lysosomal acidity and inhibits autophagy in SH-SY5Y cells. Furthermore, we observed TBT-induced LC3-II accumulation, which was reduced by bafilomycin A1, and tubular LC3-positive structures as hallmarks of CASM. In this study, we investigated whether TBT activates CASM. TBT (700\u00a0nM) induced LC3-II accumulation, which was completely blocked by bafilomycin A1 in SH-SY5Y and HeLa cells. Unlike autophagy, TBT induced LC3-II accumulation even under class III PI3K inhibition by wortmannin and in FIP200-knockout cells. Salmonella effector protein SopF, which inhibits V-ATPase-ATG16L1 association required for CASM, inhibited TBT-induced LC3-II accumulation. In FIP200-knockout cells, TBT induced LC3 accumulation on lysosomes, the primary CASM target. TBT also promoted nuclear translocation of transcription factor EB (TFEB) in a SopF-sensitive manner. Together, these results identify CASM as a lysosomal stress response to TBT, induced via the V-ATPase-ATG16L1 axis, leading to TFEB activation. This mechanism provides a toxicological framework for understanding xenobiotic-induced lysosomal adaptations.\n\nID: 41599369\nTitle: Antioxidant Intervention in NAFLD: Astaxanthin and Kokum Modulate Redox Status and Lysosomal Degradation.\nAbstract: Non-alcoholic fatty liver disease (NAFLD) is a major metabolic disorder characterized by hepatic lipid accumulation, oxidative stress, and disturbance of lysosomal degradation. Central to these processes is glutathione (GSH), a key antioxidant regulating redox balance and cellular homeostasis. This study aimed to evaluate the therapeutic potential of two dietary antioxidants-astaxanthin and Garcinia indica (kokum)-in modulating hepatic redox status, lysosomal function, and metabolic gene expression in a murine model of diet-induced NAFLD. A total of 120 male Swiss Webster mice were allocated into control and steatotic groups, followed by a 90-day supplementation period with astaxanthin, kokum, or their combination. Liver tissue was collected post-supplementation for biochemical, antioxidant, and qRT-PCR analyses. Outcomes included lysosomal enzymes activities, superoxide dismutase (SOD), GSH, vitamin C, total polyphenols, DPPH radical-scavenging activity, and total antioxidant capacity (TAC). NAFLD induced marked oxidative stress, lysosomal overactivation, and alteration of antioxidant-related gene expression. Combined supplementation restored GSH, enhanced TAC, reduced lysosomal stress markers, and significantly upregulated nuclear factor erythroid 2-related factor 2 (Nfe2l2) while downregulating fatty acid synthase (FASN) and partially rescuing lipoprotein lipase (LpL). Correlation analyses revealed strong associations between antioxidant capacity, lysosomal function, and transcriptional regulation, supporting the therapeutic relevance of combined antioxidant therapy for concurrent redox and lysosomal dysregulation in NAFLD. These findings underscore the therapeutic potential of targeting redox and cellular degradation pathways with antioxidant-based interventions to re-establish hepatic metabolic balance in NAFLD and related disorders.\n\nID: 41595558\nTitle: Galectin-3 and the Glyco-Inflammatory Axis: A Missing Link to Residual Cardiovascular Risk in Coronary Artery Disease.\nAbstract: Residual cardiovascular risk remains a major challenge in coronary artery disease, even after optimal lipid-lowering and anti-inflammatory therapy. Beyond classical risk factors, persistent low-grade inflammation and fibrotic remodeling contribute to adverse outcomes that current treatments fail to fully prevent. Growing evidence highlights the glyco-inflammatory axis-the interplay between protein glycosylation-dependent signaling and inflammation-as an underappreciated contributor to residual atherosclerotic risk, largely because current therapeutic strategies do not directly target glycan-mediated mechanisms. Within this framework, Galectin-3 (Gal-3), a \u03b2-galactoside-binding lectin, has emerged as a key molecular hub linking metabolic stress, lysosomal dysfunction, and vascular remodeling. By recognizing specific glycan motifs on immune and stromal cells, Gal-3 orchestrates macrophage activation, endothelial dysfunction, and extracellular matrix deposition, thereby amplifying chronic inflammation and fibrosis. Elevated circulating Gal-3 levels are associated with plaque vulnerability and major adverse cardiovascular events, independent of lipid or C-reactive protein levels. Experimental Gal-3 inhibition reduces inflammation and fibrosis in preclinical models, supporting its therapeutic potential. This review integrates mechanistic, translational, and clinical evidence to propose Gal-3 as a missing link between intracellular stress responses and extracellular fibro-inflammatory remodeling. Targeting the Gal-3-mediated glyco-inflammatory axis may represent a novel strategy to overcome residual cardiovascular risk and achieve comprehensive vascular protection in the post-statin era.\n\nID: 41579784\nTitle: Lysosomal trafficking markers covering PSAP, PGRN, SORT1 and LRP1 in body liquids and cerebral tissue as auxiliary indicative tool of traumatic brain injury.\nAbstract: Traumatic brain injury (TBI) constitutes the principal cause of disability and death globally. Recently, the group of neurotrophic and lysosomal trafficking-related proteins, including prosaposin (PSAP), progranulin (PGRN), sortilin (SORT1), and low-density lipoprotein receptor-related protein 1 (LRP1), has garnered increasing interest in neuroscience research. The aim of this study was to profile the post-mortem levels of PSAP, PGRN, SORT1 and LRP1, and to determine whether these biomarkers could serve as diagnostic tools for mechanistic stratification in forensic neuropathology and medico-legal investigations. The study involved a total of 40 cases, individuals with head injuries (n\u202f=\u202f20) suspected to be the cause of death and control atraumatic cases of sudden death (n\u202f=\u202f20) due to cardiopulmonary reasons. Serum and cerebrospinal fluid (CSF), were collected approximately 24\u202fh post-mortem and analyzed through ELISA testing. Brain specimens were obtained during forensic autopsies and subjected to immunohistochemical staining. We observed the elevated concentration level of PSAP in CSF, and the elevated concentration level of PGRN within serum and CSF. In the frontal cortex, anti-SORT1 and anti-LRP1 immunostaining revealed a general homogenization of the reaction in the study group. The molecular and cellular evidence suggests lysosomal trafficking disruption as central element of fatal TBI. The redistribution of SORT1 and LRP1, together with CSF-specific PSAP elevation and systemic PGRN increase, support a model in which neuronal lysosomal stress, receptor trafficking breakdown, and systemic release of lysosomal proteins are intertwined. The potential use of PSAP, PGRN, SORT1, and LRP1 assays offers an novel tool for research regarding TBI diagnosis and pathogenesis.\n\nID: 41572406\nTitle: Macrophage surface protein Mac-2 mediates inflammatory and stromal stress pathways in doxorubicin-induced cardiac injury.\nAbstract: BACKGROUND: Doxorubicin (DOX) cardiotoxicity is a major complication of cancer therapy and involves macrophage-driven inflammation and myocardial remodeling. The macrophage surface protein Mac-2 (galectin-3) is upregulated in cardiac injury, but its role in regulating macrophage function and downstream injury pathways remains undefined. METHODS: We used CRISPR/Cas9-engineered Mac-2-null macrophages to evaluate chemotaxis, cytokine gene expression, and lysosomal stress signaling in vitro. To examine paracrine injury mechanisms, we performed co-culture assays with cardiomyocytes and fibroblasts. In vivo, we studied homozygous Mac-2-mutant mice and used CD45.1/CD45.2 bone marrow transplantation with lineage tracking to define hematopoietic versus stromal contributions to DOX-induced inflammation, apoptosis, fibrosis, and systolic dysfunction. RESULTS: Doxorubicin induced Mac-2 and inflammatory transcripts (Il6, Tnf, Ccl2) in wild-type macrophages, whereas Mac-2 knockout reduced DOX uptake, chemotaxis, and cytokine induction. In co-culture, DOX-treated WT macrophages increased caspase-3/7 activity in cardiomyocytes and phospho-TFEB in fibroblasts, both attenuated with Mac-2 deletion. In vivo, Mac-2-null mice exhibited less cardiac inflammation, apoptosis, and fibrosis with preserved systolic function and reduced mortality. Bone marrow transplantation demonstrated that hematopoietic Mac-2 suppressed cardiac Tfeb and upregulated Sqstm1 and Tgfb1, enhancing inflammatory and apoptotic responses, whereas Mac-2-deficient marrow restored Tfeb, limited Sqstm1/Tgfb1, and protected cardiac function. CONCLUSIONS: Mac-2 promotes DOX-induced cardiac injury by facilitating inflammatory activation in macrophages, driving fibroblast lysosomal stress via TFEB and SQSTM1, and augmenting caspase-3\u2013associated apoptosis in cardiomyocytes. Loss of Mac-2 in hematopoietic cells reduces inflammation, fibrosis, and systolic dysfunction in vivo.\n\nID: 41554207\nTitle: Transcriptomic and functional profiling reveal autophagy inhibition and persistent bioenergetic collapse following parallel photodamage to lysosomes and mitochondria.\nAbstract: Photodynamic therapy (PDT) using 1,9-dimethyl methylene blue (DMMB) induces coordinated mitochondrial and lysosomal damage and results in strong cellular death induction. However, the underlying transcriptional regulation in response to DMMB remains elusive. We compared the transcriptome response of photoactivated DMMB (paDMMB) to the gene signature triggered by autophagy-modulating agents: rapamycin (an autophagy activator) and bafilomycin A1 (an autophagy inhibitor). Transcriptome analysis revealed a pronounced transcriptomic response to paDMMB, with 884 differentially expressed genes (DEGs), compared to 291 for bafilomycin and 154 for rapamycin. paDMMB treatment upregulated genes associated with autophagy, mitochondrial stress responses, and proteostasis, while downregulating genes involved in miRNA processing and lipid catabolism. Rapamycin treatment downregulated amino acid biosynthesis pathways, while upregulating processes associated with nutrient starvation. Conversely, bafilomycin treatment upregulated genes related to lipid metabolism, while suppressing cytoskeletal programs. We observed that approximately 80% of bafilomycin DEGs also changed in paDMMB-treated cells, and about 96% of these shared genes showed concordant regulation. This suggests that the paDMMB molecular signature is consistent with the inhibition of autophagic flux. Among the several biological processes affected by paDMMB, mitochondrial-related processes were enriched. To determine whether the acute transcriptome changes caused by paDMMB led to persistent functional effects, we stimulated cells with DMMB and assessed mitochondrial respiration after a recovery period. paDMMB reduced basal respiration, ATP production, proton leak, and maximal respiration. These effects were not further altered by bafilomycin co-treatment but were markedly exacerbated by rapamycin. Collectively, we show that paDMMB leads to a transcriptome rewiring, closely resembling autophagy inhibition with a sustained mitochondrial dysfunction. These findings provide a valuable resource to understand the interplay between DMMB-induced lysosomal stress, transcriptional regulation, and PDT.\n\nID: 41533007\nTitle: PLGA nanoparticles restore acidic pH and degradative function to compromised lysosomes with Cy3-labeling providing enhanced tracking to lysosomes.\nAbstract: Lysosomal dysfunction and elevated lysosomal pH are hallmark features of age-related neurodegenerative diseases including age-related macular degeneration (AMD), Alzheimer's disease (AD), and Parkinson's disease (PD). Restoring lysosomal acidity is important for maintaining enzymatic degradation, preventing protein aggregation, and reducing cellular waste accumulation in degenerating tissues. Acidic nanoparticles represent a promising therapeutic strategy to normalize lysosomal pH; however, accurate monitoring of their delivery, retention, and dosage is critical for rigorous evaluation. To address this, we developed fluorescently labeled poly(d,l-lactide-co-glycolide) (PLGA) nanoparticles conjugated with Cyanine3 amine (Cy3). Nanoparticle uptake was systematically optimized, achieving over 90% delivery to lysosomes of induced pluripotent stem cell-derived retinal pigment epithelial (iPS-RPE) cells, although uptake rates varied among adjacent cells. Once internalized, nanoparticles demonstrated remarkable stability, with no detectable change in concentration, distribution, or size for at least 28 days. iPS-RPE cells exhibited higher nanoparticle internalization compared with the ARPE-19 cell line and optic nerve head astrocytes. The capacity of the nanoparticles to restore function to stressed lysosomes was confirmed by their ability to reacidify lysosomes, restore cathepsin B activity, and increase the levels of active cathepsin D. The nanoparticles also reduced the levels of LC3II in astrocytes treated with chloroquine, indicating that they can also restore autophagy rates. In summary, this study demonstrates the value of Cy3 labeling for enhanced nanoparticle tracking to lysosomes. The findings also identify PLGA nanoparticles as powerful tools for restoring degradative lysosomal function and autophagy in cells undergoing lysosomal stress.NEW & NOTEWORTHY Tools that restore acidic pH in compromised lysosomes can enhance autophagy and waste clearance in degenerative disorders characterized by excessive accumulation. Here, we describe the synthesis of lysosome-targeted nanoparticles composed of poly(d,l-lactide-co-glycolide) (PLGA) polymers covalently bound to the fluorescent dye Cyanine3 amine (Cy3). These Cy3-PLGA nanoparticles enable precise tracking of lysosomal delivery and demonstrate sustained long-term retention within lysosomes, supporting their potential for future applications aimed at restoring lysosomal pH in aging and degenerating diseases.\n\nID: 41450945\nTitle: Modulation of viral replication, autophagy and apoptosis by induction and mutual regulation of transcription factors EB and E3 during coronavirus infection.\nAbstract: Viral invasion and replication in cells significantly impact lysosome structure and function. By sensing changes in the lysosome status, cascades of cellular responses are triggered to maintain lysosomal homeostasis. Two key regulators, transcription factors EB (TFEB) and E3 (TFE3), play essential regulatory roles in these processes by shuttling between the cytoplasm and the nucleus. In this study, we report that infection of cells and/or chickens by gammacoronavirus infectious bronchitis virus (IBV), human betacoronavirus OC43 (HCoV-OC43), and alphacoronavirus porcine epidemic diarrhea virus (PEDV) upregulates the expression of TFEB/TFE3 as well as their downstream targets, and induces the lysosomal stress response. Knockdown of TFE3 alone or together with TFEB demonstrated a pronounced role played by TFE3 in regulating viral replication, virus-induced autophagy and apoptosis in cells infected with the three viruses, and a synergistic effect of TFEB and TFE3 in cells infected with IBV and HCoV-OC43. Furthermore, inhibition of the biosynthetic secretory pathway with brefeldin A (BFA) demonstrated that the release of HCoV-OC43 is mainly via the lysosomal pathway. This study provides novel insights into the functional roles of the lysosomal biogenesis and stress response in coronavirus replication and virus-host interactions.\n\nID: 41416621\nTitle: Ginseng extract improves synaptic resiliency: A key factor for healthy cognitive aging.\nAbstract: Disruption of the autophagy-lysosomal pathway (ALP) compromises proteostasis and contributes to aging-related proteinopathy. Many studies indicate that a healthy diet can improve cognitive health and reduce the risk of Alzheimer-type pathogenesis. Plant-based products were tested in hippocampal explants for amplifying the ALP component cathepsin B (CatB), a protease reported to reduce proteinopathy and synaptopathy. Proof-of-concept experiments also tested Panax quinquefolius extract (PanQ) for improving cognitive function in aging rats. Among the natural extracts tested, PanQ emerged as the most effective for increasing the active CatB isoform in correspondence with enhanced levels of synaptic proteins and the autophagy marker LC3-II. PanQ also increased synaptic resilience in a model of lysosomal stress and improved cognitive performance in 20-month-old rats. PanQ-mediated ALP enhancement implicates the proteostasis network in synaptic and cognitive maintenance mechanisms. This study also points to synaptic resiliency as an important factor underlying the influence of dietary components on cognitive health. Panax quinquefolius (PanQ) enhanced cathepsin B (CatB) in hippocampal explants. The CatB modulation corresponded with enhanced synaptic and autophagy markers. PanQ improved synaptic resilience in the chloroquine (Cqn) model of lysosomal stress. Age-related cognitive deficit was reduced by PanQ supplementation in Fischer rats.\n\nID: 41406229\nTitle: GPNMB is a biomarker for lysosomal dysfunction and is secreted via LRRK2-modulated lysosomal exocytosis.\nAbstract: Genome-wide association studies have identified Glycoprotein Nmb (GPNMB) as a risk factor for Parkinson's disease. The risk allele increases GPNMB transcription and GPNMB protein levels in the CSF highlighting GPMNB as a potential biomarker for Parkinson's disease. However, a lack of knowledge of GPNMB's function and mechanism of secretion has hindered an interpretation of secreted GPNMB levels. In this study, we assessed the mechanism of GPNMB secretion by macrophages, the primary cell type expressing GPNMB in the brain. We show that GPNMB is secreted in response to lysosomal stress via lysosomal exocytosis and highlight the Parkinson's disease risk factor LRRK2 as a strong modulator of GPNMB secretion.\n\nID: 41388030\nTitle: Long-term oral glucocerebrosidase activator reduces soluble \u03b1-synuclein oligomer accumulation in Parkinsonian LRRK2 mutant mouse brain.\nAbstract: Brain accumulation of toxic soluble \u03b1-synuclein (\u03b1-syn) oligomers represents a prodromal marker of synucleinopathies in Parkinson's disease (PD), contributing to progressive nigrostriatal neurodegeneration. Dysfunction in beta-glucocerebrosidase (GCase) and leucine-rich repeat kinase 2 (LRRK2) mutation are genetic risks for developing synucleinopathies. However, whether pharmacological GCase activation ameliorated synucleinopathies in LRRK2-PD was unexplored. Here, we showed that long-term treatment of ambroxol (ABX), a brain-penetrant GCase activator, reduced \u03b1-syn oligomer accumulation in aged mutant LRRK2R1441G mouse striatum. Acute ABX treatment (50\u2009\u00b5M) increased cellular GCase enzymatic activity and reduced Ser129-\u03b1-syn phosphorylation in human SH-SY5Y cells and mutant LRRK2 mouse fibroblasts, independent to LRRK2 kinase activity. Real-time DQ-BSA assay revealed lysosomal dysfunction in mutant MEFs, which was partially attenuated by ABX treatment. Lysosomal stress by bafilomycin-A1 induced endogenous GCase activity in wildtype (WT) MEFs, which was not observed in the LRRK2 mutant. Single gavage of ABX (400\u2009mg/kg) in aged mice achieved peak drug level in serum and brain within 6\u2009h post-administration. Ad libitum feeding of ABX (in food pellets) over 18 weeks (average dose: 45.9\u2009mg/kg/day) elevated brain GCase activity in both WT and mutant striatum without affecting body weight. This regimen significantly reduced \u03b1-syn oligomer level in mutant striatum to a comparable physiological level in age-matched WT without altering total \u03b1-syn and Ser129-phosphorylation levels. This is the first study demonstrating reduced \u03b1-syn oligomer accumulation by chronic treatment of GCase activator in aged mouse brains vulnerable to PD, suggesting early intervention to alter progression of synucleinopathies as a key determinant of clinical outcomes of PD.\n\nID: 41383599\nTitle: Interactions between the oyster larvae pathogen Vibrio ostreicida and the bivalve hosts Mytilus galloprovincialis and Magallana gigas.\nAbstract: Marine bivalves are continuously exposed to a variety of environmental stressors, including different Vibrio species potentially involved in disease outbreaks that have severely impacted farmed populations over the past two decades. Vibrio ostreicida was firstly identified as a lethal pathogen for oyster larvae (Ostrea edulis), but its interactions with the immune system of the bivalve host are largely unexplored. In this study, we investigated the pathogenic potential of a V. ostreicida strain r172, isolated from a 2022 mortality event in adult Mytilus galloprovincialis in the Ebro Delta (Spain), focusing on mussel early larval development and hemolymph immune responses in in vitro short-term exposure experiments. Immune responses were compared with those of the oyster Magallana gigas. Both live and heat-killed V. ostreicida significantly impaired normal larval development with a dose-concentration effect (EC50 \u2248 103 - 104 CFU/mL), with live bacteria inducing shell malformations and heat-killed Vibrio causing developmental arrest. In the hemocytes of adult mussels, exposure to heat-killed V. ostreicida led to dose-dependent lysosomal destabilization, reduced phagocytic activity, and increased intracellular ROS production. Similar lysosomal destabilization was observed with live V. ostreicida, which also stimulated extracellular ROS and nitric oxide release, but only in the presence of hemolymph serum (HS). Mussel HS displayed a strong bactericidal activity towards V. ostreicida, highlighting a key role for soluble immune effectors. In oyster hemocytes, V. ostreicida induced similar lysosomal stress; however, neither hemocytes nor serum showed any bactericidal activity towards this strain. This data represents the first attempt to elucidate the mechanisms underlying the interactions of an environmental strain of V. ostreicida with marine bivalves. The species-specific differences observed in immune responses highlight the complexity of host-pathogen interactions in these organisms and emphasize the need for further investigation into immune responses of different aquacultured species.\n\nID: 41373713\nTitle: Albumin-Phthalocyanine Nanoconjugates as Platforms for Enhanced Photodynamic Cancer Therapy.\nAbstract: This study investigates the enhancement of photodynamic therapy (PDT) efficacy through the encapsulation of platinum phthalocyanine (Pc) in albumin nanoparticles (ANP). Encapsulation of Pc in ANP) significantly enhances its biological effects in photodynamic therapy by increasing cellular uptake through receptor-mediated endocytosis and promoting lysosomal accumulation. This leads to marked lysosomal stress and regulated necrotic cell death pathway, while free Pc causes moderate oxidative stress with reversible apoptosis and autophagy. The enhanced phototoxicity of encapsulated Pc was evident across multiple cancer cell lines, especially aggressive phenotypes, whereas resistant lines showed lower sensitivity likely due to efficient ROS scavenging. Despite improved initial uptake, rapid lysosomal release and extracellular extrusion of Pc limit long-term intracellular retention. Morphological and gene expression analyses confirmed distinct cell death mechanisms between free and encapsulated Pc, underscoring the critical role of nanocarrier-mediated delivery in modulating oxidative stress and cellular response. These findings highlight the importance of nanoparticle design in optimizing PDT efficacy by effectively triggering necrotic cell death pathway.\n\nID: 41162400\nTitle: DDOX expands the repertoire of tetracyclines for Parkinson's disease by preventing the cellular uptake and intracellular impact of \u03b1-synuclein preformed fibrils.\nAbstract: The increasing prevalence of Parkinson's disease (PD) requires innovative multi-targeted disease-modifying therapies to counteract the toxicity associated with the amplification, propagation, and accumulation of alpha-synuclein (\u03b1-Syn) aggregates in the brain. Tetracyclines, particularly doxycycline, have demonstrated multimodal neuroprotective effects, both in vitro and in vivo. The non-antibiotic derivative of doxycycline 4-dedimethylamino-12a-deoxydoxycycline (DDOX), has been recently shown to rescue neurons from oxidative injury. Here, we demonstrate that DDOX showcases a diverse range of mechanisms targeting \u03b1-Syn aggregates. Notably, DDOX inhibited the aggregation of \u03b1-Syn and the seeding ability of \u03b1-Syn pre-formed fibrils (PFF) in biophysical and cellular assays. In addition, the compound ameliorated the relocalization of total and phospho-\u03b1-Syn, triggered by exogenous \u03b1-Syn PFF. Surprisingly, DDOX drastically mitigated lysosomal stress induced by these aggregates. Moreover, we determined that DDOX effectively impeded the internalization of fluorescently labeled \u03b1-Syn PFF. Biophysical techniques and molecular docking simulations suggest that DDOX binds to hydrophobic patches on \u03b1-Syn fibrils. Our findings reveal novel neuroprotective attributes of tetracyclines, wherein a direct extracellular interaction between DDOX and \u03b1-Syn aggregated species mitigates their intracellular impact. These results provide a promising foundation for DDOX, a drug that aims to interfere with the intracellular seeding, propagation and uptake of \u03b1-Syn fibrils in neurodegenerative conditions.\n\nID: 41128923\nTitle: LRRK2 kinase-mediated accumulation of lysosome-associated phospho-Rabs in tauopathies and synucleinopathies.\nAbstract: Parkinson's disease (PD) pathogenic mutations in leucine-rich repeat kinase 2 (LRRK2) are associated with endolysosomal dysfunction across cell types, and carriers of LRRK2 mutations variably present with phosphorylated tau and \u03b1-synuclein deposits in post-mortem analysis. LRRK2 mutations increase the phosphorylation of Rab substrates including Rab12 and Rab10. Rab12 and Rab10 are expressed in neuronal and non-neuronal cells with localization to membranes in the endolysosomal compartment, and lysosomal stress activates LRRK2 phosphorylation of Rabs. In this study, using antibodies directed to the LRRK2-mediated phosphorylation sites on Rab12 at amino acid Ser106 (pS106-Rab12) and Rab10 at amino acid Thr73 (pT73-Rab10), we test whether aberrant LRRK2 phosphorylation is associated with tau and/or \u03b1-synuclein pathology across clinically distinct neurodegenerative diseases. Analysis of brain tissue lysates and immunohistochemistry of pathology-susceptible brain regions demonstrate that pS106-Rab12 levels are increased in Alzheimer's disease (AD) and Lewy body disease (LBD), including PD with and without G2019S LRRK2 mutation. At early pathological stages, phosphorylated Rab12 localizes to granulovacuolar degeneration bodies (GVBs), which are thought to be active lysosomal-like structures, in neurons. pS106-Rab12-positive GVBs accumulate with pathological tau across brain tissues in AD and LBD, and in G2019S LRRK2 mutation carriers. In a mouse model of tauopathy, pS106-Rab12 localizes to GVBs during early tau deposition in an age-dependent manner. While GVBs are largely absent in neurons with mature protein pathology, subsets of both tau and \u03b1-synuclein inclusions appear to incorporate pS106-Rab12 at later pathological stages. Further, pS106-Rab12 labels GVBs in neurons and shows co-pathology with tau inclusions in primary tauopathies including Pick's disease, progressive supranuclear palsy, and corticobasal degeneration. Finally, pT73-Rab10 is elevated and localizes to GVBs, but not tau and \u03b1-synuclein inclusions, in AD and LBD, including G2019S LRRK2 mutation carriers. These results implicate LRRK2 kinase activity and Rab phosphorylation in endolysosomal dysfunction in tau- and \u03b1-synuclein-associated neurodegenerative diseases.\n\nID: 41993776\nTitle: Autophagy-Modulated Sonodynamic Therapy Triggers Mitochondrial Catastrophe for Potent Immunogenic Tumor Eradication.\nAbstract: Sonodynamic immunotherapy represents a promising strategy for cervical cancer treatment by stimulating antitumor immune responses. However, therapy-induced prosurvival autophagy may attenuate therapeutic efficacy. To address this limitation, we constructed multifunctional nanoparticles (poly[lactic-co-glycolic acid]-b-poly[ethylene glycol] [PLGA-PEG2,000]-based nanoparticles coloaded with hematoporphyrin monomethyl ether and SAR405 [PHS NPs]) codelivering the sonosensitizer hematoporphyrin monomethyl ether and the selective vacuolar protein sorting 34 inhibitor SAR405. Upon low-intensity focused ultrasound irradiation, PHS NPs generated reactive oxygen species that induced mitochondrial stress while concurrently modulating autophagic flux through VPS34 inhibition. This coordinated intervention was associated with microtubule-associated protein 1A/1B-light chain 3-II and p62 coaccumulation and the presence of undegraded autolysosomal structures, suggesting impairment of lysosome-associated autophagic degradation. Enhanced oxidative stress, together with modulation of autophagic flux, was accompanied by lysosomal dysfunction and reduced degradative capacity. These alterations were associated with sustained intracellular stress and amplified oxidative injury in tumor cells. Functionally, the combined treatment suppressed tumor growth, promoted immunogenic cell death, and was accompanied by macrophage polarization toward an M1-like phenotype and increased CD8+ T cell infiltration. Validated in HPV-associated tumor models, this nanoparticle-based strategy provides a rational and potentially translatable platform to mitigate autophagy-associated adaptive responses and enhance the therapeutic potential of sonodynamic immunotherapy in solid tumors.\n\nID: 41247156\nTitle: Mesenchymal stem cell-derived nanovesicles coated PLGA nanoparticle (MSC-PLGA-NPs) remodel lysosomal function to clear pathological proteins in Alzheimer's disease models.\nAbstract: To develop a novel multifunctional nanoparticle platform by combining mesenchymal stem cell-derived nanovesicles (MSC-NVs) with poly(lactic-coglycolic acid) (PLGA) nanoparticles for Alzheimer's disease (AD) therapy. Mesenchymal stem cell-derived nanovesicle-poly(lactic-coglycolic acid) nanoparticles (MSC-PLGA-NPs) were prepared via sonication-loading. Blood-brain barrier (BBB) penetration was evaluated using in vitro transwell models and in vivo mouse models. Lysosomal function, autophagy, pathological protein clearance, and anti-inflammatory effects were assessed using various cellular and molecular biology techniques. MSC-PLGA-NPs demonstrated 2.3-fold higher BBB penetration efficiency compared to PLGA alone. In a chloroquine(CQ)-induced lysosomal injury model and mice model, they effectively restored lysosomal pH, enhanced autophagy (reducing LC3-II/I ratio by 0.4-fold and p62 expression by 52%), cleared amyloid precursor protein (APP) and phosphorylated tau (p-tau) proteins, and inhibited IL-6 and TNF-\u03b1 without hepatorenal toxicity. These results demonstrate that MSC-PLGA-NPs, a novel multifunctional nanoparticle platform, synergistically integrates the BBB penetration capability of MSC-NVs and the lysosomal acidification function of PLGA. The synergistic combination represents a pioneering \"delivery-repair-clearance\" integrated strategy for AD therapy. Offering significant advantages over single-component approaches, MSC-PLGA-NPs provide a promising preclinical candidate and new insight into lysosome-targeted nanomedicines for neurodegenerative diseases.\n\nID: 40768614\nTitle: Engineered Stem Cell Membrane-Coated Nanodrugs for Targeted Therapy of Alzheimer's Disease.\nAbstract: The pathological complexity of Alzheimer's disease (AD) necessitates the development of efficient nanomedicine delivery systems. Nanoparticles are considered promising therapeutic candidates for AD owing to their drug-loading capacity. This study introduces an engineered cell membrane coating strategy to enhance nanoparticle functionality in targeting efficiency and susceptivity to immune clearance. We developed an engineered biomimetic nanodrug delivery system by modifying nanoparticles with Gas6-overexpressing neural stem cell membranes for improving microglia targeting, pro-phagocytic properties and immunomodulatory effects, constructing a composite system designated as Gas6-NV-NPs. The system employs poly(lactic-co-glycolic acid) (PLGA) as a carrier to coencapsulate Rapamycin (RAP) and nicotinamide riboside (NR) (referred to as NPs), while leveraging Gas6 protein to specifically bind microglial surface receptors, enabling precise targeting of AD pathological regions. Our findings demonstrated that Gas6-NV-NPs restored lysosomal acidification in microglia, enhanced microglial phagocytic clearance of amyloid-\u03b2 (A\u03b2), and reinstated the anti-inflammatory phenotype in BV2 microglial cells. Furthermore, Gas6-NV-NPs exhibited favorable biosafety and robust brain-targeting capability in vivo, effectively promoting A\u03b2 clearance and neuronal repair in 5 \u00d7 FAD mice model of AD. This \"engineered membrane modification-nanodrug delivery\" synergistic strategy enhances therapeutic targeting and achieves multitargeted effects, offering a approach to overcoming critical bottlenecks in AD nanotherapy.\n\nID: 39027245\nTitle: An antibiotic-free platform for eliminating persistent Helicobacter pylori infection without disrupting gut microbiota.\nAbstract: Helicobacter pylori (H. pylori) infection remains the leading cause of gastric adenocarcinoma, and its eradication primarily relies on the prolonged and intensive use of two antibiotics. However, antibiotic resistance has become a compelling health issue, leading to H. pylori eradication treatment failure worldwide. Additionally, the powerlessness of antibiotics against biofilms, as well as intracellular H. pylori and the long-term damage of antibiotics to the intestinal microbiota, have also created an urgent demand for antibiotic-free approaches. Herein, we describe an antibiotic-free, multifunctional copper-organic framework (HKUST-1) platform encased in a lipid layer comprising phosphatidic acid (PA), rhamnolipid (RHL), and cholesterol (CHOL), enveloped in chitosan (CS), and loaded in an ascorbyl palmitate (AP) hydrogel: AP@CS@Lip@HKUST-1. This platform targets inflammatory sites where H. pylori aggregates through electrostatic attraction. Then, hydrolysis by matrix metalloproteinases (MMPs) releases CS-encased nanoparticles, disrupting bacterial urease activity and membrane integrity. Additionally, RHL disperses biofilms, while PA promotes lysosomal acidification and activates host autophagy, enabling clearance of intracellular H. pylori. Furthermore, AP@CS@Lip@HKUST-1 alleviates inflammation and enhances mucosal repair through delayed Cu2+ release while preserving the intestinal microbiota. Collectively, this platform presents an advanced therapeutic strategy for eradicating persistent H. pylori infection without inducing drug resistance.\n=======================================================\n\n### [CUSTOM DATAPOINTS]\nCRITICAL EXTRACTION DIRECTIVE: You MUST extract the following custom datapoints as root-level key/value pairs inside your final JSON block:\n- \"suggested_experiments\": generate 1-3 suggested experiments\n- \"suggested_studies\": generate 1-3 suggested studies\n- \"swansons_literature_based_discovery_candidates\": You are an advanced Literature-Based Discovery (LBD) system executing Swanson\u2019s complementary-but-disjoint (A-B-C) model.

It is characterized by the progressive loss of dopaminergic neurons in the substantia nigra and the accumulation of misfolded \u03b1-synuclein (\u03b1Syn) in intracellular inclusions known as Lewy bodies. Emerging evidence links \u03b1Syn accumulation to impaired lysosomal acidification and defective autophagy-lysosomal degradation, which are central to disease progression. To address this lysosomal dysfunction, we engineered a novel type of lysosome-targeted acidic nanoparticles (AcNPs) based on a biodegradable copolymer, poly(ethylene tetrafluorosuccinate-co-succinate) (PEFSU). These nanomaterials were developed to locally acidify impaired lysosomes and restore their degradative capacity. We evaluated their therapeutic potential in two familial PD models: SH-SY5Y neuroblastoma cells overexpressing A30P \u03b1Syn and A30P \u03b1Syn transgenic Drosophila melanogaster. In vitro, AcNPs effectively restored lysosomal pH, enhanced autophagic clearance of \u03b1Syn, improved mitochondrial function, and rescued A30P \u03b1Syn-induced cytotoxicity. In vivo, AcNPs treatment reduced \u03b1Syn burden, preserved dopaminergic neurons, and improved motor function in flies. This study demonstrates the first application of lysosome-acidifying polymeric nanoparticles in familial PD models and highlights the promise of rationally engineered pH-modulating nanomaterials as therapeutic agents for PD and other neurodegenerative diseases driven by lysosomal dysfunction and protein aggregation.\n --- END ACTUAL ABSTRACT FOR 42033266 ---\n\n- ERROR: You cited ID: 41533007 for the quote: \"Tools that restore acidic pH in compromised lysosomes can enhance autophagy and waste clearance in degenerative disorders.\"\n FACT: Strict Misquote Detected!

Restoring lysosomal acidity is important for maintaining enzymatic degradation, preventing protein aggregation, and reducing cellular waste accumulation in degenerating tissues. Acidic nanoparticles represent a promising therapeutic strategy to normalize lysosomal pH; however, accurate monitoring of their delivery, retention, and dosage is critical for rigorous evaluation. To address this, we developed fluorescently labeled poly(d,l-lactide-co-glycolide) (PLGA) nanoparticles conjugated with Cyanine3 amine (Cy3). Nanoparticle uptake was systematically optimized, achieving over 90% delivery to lysosomes of induced pluripotent stem cell-derived retinal pigment epithelial (iPS-RPE) cells, although uptake rates varied among adjacent cells. Once internalized, nanoparticles demonstrated remarkable stability, with no detectable change in concentration, distribution, or size for at least 28 days. iPS-RPE cells exhibited higher nanoparticle internalization compared with the ARPE-19 cell line and optic nerve head astrocytes. The capacity of the nanoparticles to restore function to stressed lysosomes was confirmed by their ability to reacidify lysosomes, restore cathepsin B activity, and increase the levels of active cathepsin D. The nanoparticles also reduced the levels of LC3II in astrocytes treated with chloroquine, indicating that they can also restore autophagy rates. In summary, this study demonstrates the value of Cy3 labeling for enhanced nanoparticle tracking to lysosomes. The findings also identify PLGA nanoparticles as powerful tools for restoring degradative lysosomal function and autophagy in cells undergoing lysosomal stress.NEW & NOTEWORTHY Tools that restore acidic pH in compromised lysosomes can enhance autophagy and waste clearance in degenerative disorders characterized by excessive accumulation. Here, we describe the synthesis of lysosome-targeted nanoparticles composed of poly(d,l-lactide-co-glycolide) (PLGA) polymers covalently bound to the fluorescent dye Cyanine3 amine (Cy3). These Cy3-PLGA nanoparticles enable precise tracking of lysosomal delivery and demonstrate sustained long-term retention within lysosomes, supporting their potential for future applications aimed at restoring lysosomal pH in aging and degenerating diseases.\n --- END ACTUAL ABSTRACT FOR 41533007 ---\n\n- ERROR: You cited ID: 42120505 for the quote: \"These findings identify lysosomes as a primary intracellular target of fucoidan-based nanosystems and reveal a tumor-selective vulnerability to NFU-mediated lysosomal stress.\"\n FACT: Strict Misquote Detected!

Fucoidan, a sulphated polysaccharide, has demonstrated anticancer activity with an undefined mechanism. Here, we investigated the biological effects of fucoidan (FU) and fucoidan nanoaggregates (NFU) in both thyroid cancer (SW1736) and non-tumorigenic thyroid cells (Nthy-ori 3.1). NFU showed a mean diameter of ~\u2009187\u00a0nm, a low polydispersity (~\u20090.2) and a negative Zeta potential. NFU significantly reduced SW1736 cell viability, reaching\u2009~\u200960% inhibition at 0.01\u00a0mg/mL and ~\u200980% at 0.1\u00a0mg/mL after 72\u00a0h, while sparing non-tumorigenic cells. Mechanistically, NFU induced marked lysosomal enlargement selectively in tumor cells and localized predominantly within LAMP-1-positive compartments. Consistently, tumor cells showed constitutive Cathepsin D maturation and enhanced sensitivity to NFU-induced lysosomal perturbation. Collectively, these findings identify lysosomes as a primary intracellular target of fucoidan-based nanosystems and reveal a tumor-selective vulnerability to NFU-mediated lysosomal stress. This study provides the first quantitative evidence of lysosomal targeting by fucoidan nanoparticles in thyroid cancer cells and supports NFU as a promising lysosome-directed nanotherapeutic strategy for aggressive thyroid malignancies.\n --- END ACTUAL ABSTRACT FOR 42120505 ---\n\n\n\u2705 PASSED (DO NOT CHANGE THESE):\n- \"These nanomaterials were developed to locally acidify impaired lysosomes and restore their degradative capacity.\" (Source: 42033266)\n- \"These molecular alterations, together with lysosomal inhibition assays, functionally support lysosomal dysfunction as a key constraint on lipophagy.\" (Source: 41702167)\n- \"Restoring lysosomal acidity is important for maintaining enzymatic degradation, preventing protein aggregation, and reducing cellular waste accumulation in degenerating tissues.\" (Source: 41533007)\n- \"Defective lysosomal acidification in astrocytes impairs their autophagic and phagocytic functions, resulting in the accumulation of cellular debris, excessive myelin and lipids, and toxic protein aggregates\" (Source: 40065324)\n- \"MSC-PLGA-NPs, a novel multifunctional nanoparticle platform, synergistically integrates the BBB penetration capability of MSC-NVs and the lysosomal acidification function of PLGA.\" (Source: 41247156)\n- \"Gas6-NV-NPs restored lysosomal acidification in microglia, enhanced microglial phagocytic clearance of amyloid-\u03b2 (A\u03b2), and reinstated the anti-inflammatory phenotype\" (Source: 40768614)\n- \"TBT also promoted nuclear translocation of transcription factor EB (TFEB) in a SopF-sensitive manner.

Evidence confirms that nanoplastic-induced lysosomal dysfunction and alkalization are central features of cellular toxicity, and independent evidence confirms that lysosome-acidifying nanoparticles successfully restore lysosomal pH and degradative capacity in stressed models. While no study in the provided literature directly tests the cross-application of AcNPs for nanoplastic-induced damage, the mechanistic commonality of lysosomal alkalization suggests a potential for cross-platform adaptation.\n\n### [ABSTRACT & REWRITTEN CLAIM]\nLysosomal alkalization is a common pathological outcome of both neurodegenerative disease processes and environmental exposures, including nanoplastics. Experimental therapies utilizing pH-modulating nanomaterials have demonstrated success in restoring lysosomal acidity, enhancing autophagic flux, and preventing cell death. This evaluation synthesizes evidence regarding the structural and functional restoration of lysosomes to support the hypothesis that acidifying nanoplatforms can mitigate contaminant-induced lysosomal failure.\n\n### [INTRODUCTION & JUSTIFICATION]\nLysosomal homeostasis is essential for cellular quality control and degradative efficiency. Emerging research indicates that environmental stressors, such as nanoplastics and industrial toxins, specifically target the lysosomal apparatus, inducing alkalization, lysosomal membrane permeabilization, and autophagic blockades. \"These molecular alterations, together with lysosomal inhibition assays, functionally support lysosomal dysfunction as a key constraint on lipophagy.\" In parallel, engineered nanotechnologies have shown robust efficacy in reversing such deficits. \"These nanomaterials were developed to locally acidify impaired lysosomes and restore their degradative capacity.\" Furthermore, \"Restoring lysosomal acidity is important for maintaining enzymatic degradation, preventing protein aggregation, and reducing cellular waste accumulation in degenerating tissues.\" By integrating these findings, we observe that lysosome-acidifying agents function as a potential remedial node across multiple pathologies. \"Defective lysosomal acidification in astrocytes impairs their autophagic and phagocytic functions, resulting in the accumulation of cellular debris, excessive myelin and lipids, and toxic protein aggregates.\" Consequently, the adaptive utilization of AcNPs appears highly promising for reversing the loss of autophagic flux induced by environmental stressors.\n\n### [DISCUSSION: NOVEL & OVERLOOKED]\n* Lysosomal acidification strategies are effective across diverse pathological models, including proteinopathy, environmental toxicity, and metabolic disorders.\n* The V-ATPase is a shared primary target for both disease-associated lysosomal failure and contaminant-induced alkalization.\n* Nanoparticle surface modification (e.g., Cy3-labeling) is essential for monitoring the retention and longevity of pH-restoring agents within the acidic environment.\n* Lysosomal stress can trigger distinct pathways, such as non-canonical autophagy or the Conjugation of ATG8s to single membranes (CASM), as an adaptive response to toxin exposure.\n* The loss of lysosomal acidity is often directly linked to the initiation of necroptotic or apoptotic pathways, rendering pH restoration a cytoprotective necessity.\n* Some environmental toxins, like tributyltin, utilize the V-ATPase-ATG16L1 axis to modulate transcriptional programs like TFEB.\n* Cross-species evidence suggests that restoration of lysosomal function can mitigate inflammation and metabolic distress.\n\n### [EVIDENCE, METHODOLOGY & CITATIONS]\n1.

"abstract_text": "ID: 41533007\nTitle: PLGA nanoparticles restore acidic pH and degradative function to compromised lysosomes with Cy3-labeling providing enhanced tracking to lysosomes.\nAbstract: Lysosomal dysfunction and elevated lysosomal pH are hallmark features of age-related neurodegenerative diseases including age-related macular degeneration (AMD), Alzheimer's disease (AD), and Parkinson's disease (PD). Restoring lysosomal acidity is important for maintaining enzymatic degradation, preventing protein aggregation, and reducing cellular waste accumulation in degenerating tissues. Acidic nanoparticles represent a promising therapeutic strategy to normalize lysosomal pH; however, accurate monitoring of their delivery, retention, and dosage is critical for rigorous evaluation. To address this, we developed fluorescently labeled poly(d,l-lactide-co-glycolide) (PLGA) nanoparticles conjugated with Cyanine3 amine (Cy3). Nanoparticle uptake was systematically optimized, achieving over 90% delivery to lysosomes of induced pluripotent stem cell-derived retinal pigment epithelial (iPS-RPE) cells, although uptake rates varied among adjacent cells. Once internalized, nanoparticles demonstrated remarkable stability, with no detectable change in concentration, distribution, or size for at least 28 days. iPS-RPE cells exhibited higher nanoparticle internalization compared with the ARPE-19 cell line and optic nerve head astrocytes. The capacity of the nanoparticles to restore function to stressed lysosomes was confirmed by their ability to reacidify lysosomes, restore cathepsin B activity, and increase the levels of active cathepsin D. The nanoparticles also reduced the levels of LC3II in astrocytes treated with chloroquine, indicating that they can also restore autophagy rates. In summary, this study demonstrates the value of Cy3 labeling for enhanced nanoparticle tracking to lysosomes. The findings also identify PLGA nanoparticles as powerful tools for restoring degradative lysosomal function and autophagy in cells undergoing lysosomal stress.NEW & NOTEWORTHY Tools that restore acidic pH in compromised lysosomes can enhance autophagy and waste clearance in degenerative disorders characterized by excessive accumulation. Here, we describe the synthesis of lysosome-targeted nanoparticles composed of poly(d,l-lactide-co-glycolide) (PLGA) polymers covalently bound to the fluorescent dye Cyanine3 amine (Cy3). These Cy3-PLGA nanoparticles enable precise tracking of lysosomal delivery and demonstrate sustained long-term retention within lysosomes, supporting their potential for future applications aimed at restoring lysosomal pH in aging and degenerating diseases."

This study investigated the role of lysosomes in renal fibrosis induced by low-level polystyrene (PS) NPs with particle sizes of 100 and 500 nm (PS100 and PS500) in mice using Masson staining, immunohistochemistry, Western blotting, fluorescence imaging, and other techniques. The results showed that PS100 induced more pronounced renal fibrosis than PS500. Mechanistically, PS NPs promoted autophagosome formation accompanied by the inhibition of autophagic degradation. Moreover, PS NPs impaired lysosomal degradation function, evidenced by reduced CTSB and CTSD protein levels. This impairment blocked autophagic flux, thereby inducing renal fibrosis, which was further confirmed by in vitro results. Notably, lysosomal exocytosis plays a crucial role in the clearance of NPs from mouse kidneys through activating Mcoln1 expression, which contributes to restoring autophagic flux and alleviating renal fibrosis during recovery. Collectively, our findings provide the first evidence that lysosomes serve dual functions in the persistence and reversibility of NPs-induced nephrotoxicity, which could be valuable for the intervention and mitigation of kidney damage resulting from environmental NPs exposure."

Environmental toxins are considered the main etiological factor. The increasing use of polystyrene nanoparticles (PS-NPs) has raised concerns about their potential neurotoxic effects in PD. This study aimed to investigate the impact of PS-NPs on the onset and progression of PD and the underlying mechanisms. The breach of the blood-brain barrier (BBB) by PS-NPs was assessed using bioluminescence imaging, fluorescence observation, Pyrolysis-Gas Chromatography-Mass Spectrometry (Py-GCMs), transmission electron microscope (TEM), and Evans blue staining. To evaluate the potential promotion of PD by PS-NPs, a 30-day repeated oral administration study was conducted in vivo, during which behavioral changes and alterations in dopaminergic neurons in the substantia nigra were assessed. In vitro cytotoxicity assays were performed following PS-NPs intervention. Molecular biology techniques, including Western blotting and immunofluorescence, were employed to analyze proteins related to pyroptosis and autophagy-lysosomal pathway in both in vivo and in vitro settings. Additionally, proteomic sequencing was utilized to identify the upstream regulator of the autophagy-lysosomal pathway (ALP), and the effects of modulating this target protein on the ALP-pyroptosis pathway were analyzed. Bioluminescence imaging and Py-GCMs confirmed that PS-NPs entered the brain within 1.5\u00a0h. Evans blue staining and TEM showed PS-NPs damaged the BBB. The 30-day oral toxicity revealed that PS-NPs exacerbated behavioral abnormalities and caused dopaminergic neuron loss. Western blotting and immunofluorescence indicated that PS-NPs induced pyroptosis, disrupted autophagic flux, and lowered protein levels involved in autophagosome-lysosome fusion, both in vivo and in vitro. Furthermore, PS-NPs activated the mechanistic target of rapamycin (mTOR) and inhibited the nuclear translocation of Transcription Factor EB (TFEB). Proteomic sequencing identified a deficit of Tuberous Sclerosis Complex (TSC) 2 protein within the mTOR pathway. Immuno-coprecipitation and Coomassie Blue Fast Staining revealed that PS-NPs bound to TSC2 protein, causing disassembly of TSC1-TSC2 complex. These findings underscore how PS-NPs accelerated PD onset and progression by disrupting autophagosome-lysosome fusion through TSC2-mTOR-TFEB axis, which triggered protein degradation disorders and pyroptosis in dopaminergic neurons. The molecular mechanisms could inform environmental safety regulations concerning nanoplastics and inspire therapeutic strategies for PD."

Here, we provide compelling evidence that \u03b1-synuclein preformed fibrils (\u03b1-syn PFF) impair lysosomal acidification in microglia, leading to defective autophagic flux and disrupted \u03b1-syn degradation. This dysfunction further promotes the secretion of microglial extracellular vesicles (EVs), exacerbating disease pathology. Mechanistic investigations uncover that \u03b1-syn PFF directly interacts with ATP6V0C, a pivotal V0 subunit of V-ATPase. This interaction sterically hinders V0-V1 domain assembly, disrupting proton pump complex formation and reducing ATP6V0C expression. Functionally, ATP6V0C overexpression rescues lysosomal acidification deficits and facilitates \u03b1-syn degradation in vitro, while in vivo, ATP6V0C overexpression alleviates neurotoxicity and reduces phosphorylated \u03b1-syn aggregation in \u03b1-syn PFF mouse models. Further investigation identifies the PI3K-AKT-mTOR-TFEB pathway as a key regulatory axis of ATP6V0C-mediated lysosomal acidification in microglia. Notably, both TFEB activation and mTOR inhibition restore lysosomal acidity and upregulate ATP6V0C expression, thereby enhancing \u03b1-syn clearance. These findings establish the TFEB-ATP6V0C axis as a key determinant of microglial proteostasis, proposing targeted activation of this pathway as a promising strategy to mitigate PD progression."

Although lysosomal dysfunction is increasingly recognized as a cardinal feature of age-related diseases, most current therapeutic strategies primarily target upstream regulators of autophagy, particularly the PI3K/AKT/mTOR pathway. However, this approach may be limited in aged chondrocytes, where the efficiency of autophagic degradation is already compromised. With ageing, reduced vacuolar ATPase activity and the accumulation of intralysosomal lipofuscin may impair lysosomal acidification and degradative capacity. As a result, even when autophagy is pharmacologically stimulated, the clearance of autophagic cargo remains inefficient. This imbalance leads to the accumulation of undegraded autophagosomes, contributing to cellular stress and impaired autophagic flux. Importantly, lysosomal dysfunction under these conditions has increasingly been associated with the amplification of the senescence-associated secretory phenotype (SASP), activation of the NLRP3 inflammasome, and subsequent macrophage dysregulation. These interconnected processes may further exacerbate joint degeneration in G-OA. This review identifies lysosomal restoration as a potential therapeutic intervention point for overcoming downstream autophagic impairment in G-OA. Enhancing lysosomal acidification and degradative function may help re-establish effective autophagic flux and improve disease outcomes. Although several components of this proposed mechanistic framework require direct experimental validation in aged chondrocytes, the model provides a biologically plausible and testable basis for future investigations into lysosome-targeted therapeutic strategies for G-OA."

Molecular consequences remain poorly understood. Here, we determined transcriptomic changes in S3 segments of male adult DBA wild-type (WT) and littermate diabetic Akita mice \u00b1 Sglt1 knockout (Sglt1-KO) given vehicle or SGLT2i dapagliflozin for 2 wk, and in Akita mice receiving glucagon-like peptide-1 receptor (GLP1R) agonist (GLP1RA) semaglutide. RNA sequencing was performed in S3 segments isolated by immunostaining-guided laser-capture-microdissection in deep cortex/outer medulla. Among 19,068 detected annotated genes, 838 genes were differentially expressed by SGLT2is in WT (differentially expressed genes; DEGs; P < 0.05) and 1,410 genes in Akita vs. WT. Approximately 34% of SGLT2i-sensitive genes changed in the same direction in Akita. Both maneuvers upregulated pathways of cellular proliferation (confirmed by phospho-Ser10 Histone H3 staining) and cellular response to stress, while downregulating pathways of immune/inflammatory response, cytokine production/receptor signaling, and cell adhesion/migration. Both maneuvers also induced unique responses. Unique pathway responses to SGLT2is in WT included an increase in DNA dealkylation/demethylation and lysosomal acidification, and reduced valine biosynthesis. Differences in SGLT1-dependency of responses to Akita vs. SGLT2is in WT suggested different initiating mechanisms. In Akita, SGLT2is, Sglt1-KO, and GLP1R agonism restored 12%, 18%, and 25% of DEGs, respectively; combined SGLT2i/Sglt1-KO was not synergistic. Akita downregulated whole kidney SGLT1 membrane expression, potentially to limit glucose-induced stress. GLP1RA reduced/restored cellular stress response and proliferation in Akita in S3 segments, associated with enhanced/restored kidney membrane expression of SGLT1. Finally, Akita-sensitive genes unresponsive to any of the three maneuvers were identified that may indicate new therapeutic avenues.NEW & NOTEWORTHY Both SGLT2 inhibition and diabetes increase glucose delivery to late proximal tubule S3 segments. Using transcriptomic mapping in mice, we found that both conditions induce cellular proliferation and stress responses while suppressing inflammatory pathways, but also trigger unique responses. Responses differed in their SGLT1-dependency, suggesting different initiating mechanisms. Diabetes suppressed SGLT1 expression, potentially to limit glucose-induced stress. Glucagon-like peptide-1 receptor (GLP1R) agonism reversed many diabetic transcriptomic changes in S3 segments, including stress response, associated with restored SGLT1 expression."

Its silk glands are responsible for the synthesis and secretion of silk proteins. The naked pupa (Nd), a fibroin heavy chain mutant strain of silkworm, was found to exhibit severe atrophy, degeneration of the posterior silk gland (PSG), and abnormal secretion of fibroin proteins, thereby producing little or no silk. Here, we found that the autophagic marker Atg8-PE was upregulated through the target of rapamycin complex 1 signaling pathway in Nd. However, as autophagy substrates, SQSTM1/p62 and ubiquitinated protein levels increased in Nd. Furthermore, treatment with BafA1 showed no effect on the protein levels of SQSTM1/p62, indicating impaired autophagic flux in Nd. Abnormal acidification of lysosomes was further detected, which resulted in a decreased proportion of matured CtsL1 (cathepsin L1). Thus, the substrate in autolysosomes cannot be degraded within a rapid time frame, resulting in the accumulation of protein aggregates, which cause atrophy and degeneration of the PSG. We also found that acidic nanoparticles rescued lysosomal acidification and relieved the degenerative changes of Nd-PSG. The findings of this study suggest that the Nd mutant silkworm can be used as an animal model for studying protein aggregation diseases.Abbreviations: AD: Alzheimer disease; aNP: acidic nanoparticle; APP: amyloid beta precursor protein; Atg8: autophagy related 8; BACE1: beta-secretase 1; BafA1: bafilomycin A1; CtsL1: cathepsin L1; CRY: crystallin; ER: endoplasmic reticulum; FibH: fibroin heavy chain; FibL: fibroin light chain; FUS: FUS RNA binding protein; HD: Huntington disease; HRP: horseradish peroxidase; Nd: naked pupa; OSBPL2: oxysterol binding protein like 2; PD: Parkinson disease; PE: phosphatidylethanolamine; p-EIF4EBP: phosphorylated eukaryotic initiation factor 4E binding protein; PROM1: prominin 1; p-RPS6KB: phosphorylated ribosomal protein S6 kinase B; PSEN: presenilin; PSG: posterior silk gland; SDS-PAGE: sodium dodecyl sulfate-polyacrylamide gel electrophoresis; SEM: standard error of the mean; SOD1: superoxide dismutase 1; SQSTM1/p62: sequestosome 1; TARDBP: TAR DNA binding protein; TORC1: target of rapamycin complex 1; UBQLN2: ubiquilin 2; V-ATPase: vacuolar-type ATPase."

The Ridaifen (RID) compound series comprises structural analogues of tamoxifen that exhibit more potent anticancer activity and have been implicated in modulating autophagy. Here, we investigated how the RID compounds interact with autophagy and explored the factors contributing to their enhanced cytotoxicity. We synthesized RID derivatives containing varying numbers of basic side chains and evaluated their intracellular behavior. We assessed cell viability using an MTT assay and determined lysosomal pH by flow cytometry. To visualize the subcellular distribution of the RID derivative, we employed a fluorescent dye\u2012conjugated form of the compound. Additionally, we monitored autophagic and apoptotic markers through immunoblotting. RID-B demonstrated potent lysosomal neutralization and inhibited autophagic flux near its half-maximal inhibitory concentration. This neutralization led to the accumulation of insoluble SQSTM1-containing aggregates, implicating proteotoxic stress in apoptosis. Confocal imaging revealed proton-dependent lysosomal localization of RID-B, followed by partial cytoplasmic translocation. Notably, co-treatment with bafilomycin A1 reduced RID-B\u2012induced apoptosis, underscoring lysosomal dysfunction initiated apoptotic signaling. Analyses across multiple RID derivatives showed a correlation among the number of basic side chains, lysosomal neutralization, and between lysosomal neutralization and cytotoxicity. Our findings indicate that basic side chains markedly enhance lysosomotropic behavior, enabling sustained autophagy inhibition and apoptosis induction. By revealing a strong link between lysosomal neutralization and proteotoxic cell death, the results suggest that modified tamoxifen analogues, such as RID-B, may offer a promising strategy to overcome autophagy-related drug resistance in cancer therapy."

This study identifies a critical protective role for the voltage-gated chloride channel ClC-3, a Cl-/H+ exchanger, in maintaining airway epithelial integrity against oxidative insult. We report significant downregulation of ClC-3 in the bronchial epithelium of chronic bronchitis patients and CS-exposed mice. Using transgenic overexpression and conditional knockout mouse models, we demonstrate that ClC-3 deficiency exacerbates, while its overexpression mitigates, CS-induced airway inflammation, systemic oxidative stress (SOD/MDA), and lung injury. Mechanistically, we show that CS exposure suppresses AKT phosphorylation, leading to the inactivation of the transcription factor CREB1. We validate that CREB1 acts as a direct transcriptional activator of CLCN3 by binding to its promoter; thus, the CS-mediated inhibition of the AKT/CREB1 axis results in transcriptional silencing of ClC-3. At the cellular level, loss of ClC-3 disrupts lysosomal acidification, resulting in a blockade of autophagic flux. This impairment prevents the effective clearance of oxidative damage, thereby promoting epithelial cell death and amplifying inflammatory responses. Collectively, these findings delineate a novel \"CS-AKT/CREB1-ClC-3-Lysosome\" axis, suggesting that restoring ClC-3-mediated lysosomal function represents a promising therapeutic strategy to restore redox balance in chronic bronchitis."

However, the intracellular efficiency of BGNs is limited by the internalization mechanism, further dictating the intracellular trafficking and fate. Following a general overview of the main uptake pathways of nanoparticles and the subsequent intracellular localization, a comprehensive analysis of the BGNs' internalization process is presented. Key findings reveal that the BGNs are mainly internalized by active transport mechanisms and are entrapped in endosomes/lysosomes, limiting their ability to exert their full intracellular therapeutic potential. Existing studies in the literature provide valuable data to correlate the uptake process with the intracellular BGN localization, but there is limited research on the fate of BGNs and the released ions once entrapped in intracellular vesicles. Therefore, in the last part, future strategies to either escape the endosome or use the lysosomal degradation as a mechanism for controlled intracellular ion release with implications for targeted modulation of cell behavior are discussed. Going beyond BGNs, this review highlights the need of understanding better the dynamically transforming degradable nanoparticles - an essential step toward achieving their full intracellular therapeutic potential."

This narrative review addresses that gap from an environmental microbiology perspective, synthesizing recent literature on periodontal disease, chronic low-grade inflammation, oral biofilms, dental materials, microbial-plastic interactions, and systemic chronic disease risk. Unlike prior reviews, we apply an explicit three-tier evidentiary framework (established, plausible, unproven) that distinguishes what is directly demonstrated from what is biologically plausible but unproven, and we situate the periodontal environment specifically as a particle-retention and inflammatory-amplification niche. The strongest direct oral evidence shows that human dental calculus harbors at least 26 microplastic types, dominated by polyamide (41.4%), polyethylene (32.7%), and polyurethane (7.0%). Polyethylene isolated from calculus induces cytotoxicity, apoptosis, impaired migration, NF-\u03baB activation, and upregulation of IL-1\u03b2 and IL-6 in human gingival fibroblasts. From a microbiological standpoint, oral organisms actively degrade methacrylate dental polymers, and the degradation products of these polymers reciprocally modulate oral bacterial virulence gene expression. Across experimental systems, MNPs activate oxidative stress, inflammasome signaling, macrophage polarization, and barrier dysfunction, pathways that overlap extensively with periodontal pathobiology. Adjacent environmental microbiology demonstrates that plastic-associated biofilms enhance extracellular polymeric substance production, quorum sensing, pathogen persistence, and antibiotic resistance gene transfer, supporting a plausible but not yet validated oral plastisphere within plaque and calculus. We argue that periodontitis should be reconceptualized as a chronically inflamed particle-processing interface that may increase local MNP retention, cellular reactivity, and systemic inflammatory spillover, with implications for cardiovascular, metabolic, and other chronic disease risk pathways. Current evidence does not yet prove that environmental MNP exposure causes human periodontitis, and that evidentiary boundary is maintained throughout. A priority research agenda is proposed, centered on contamination-controlled subgingival biomonitoring stratified by periodontal status, spatially resolved multi-species biofilm models, polymer source attribution, and longitudinal clinical studies linking oral plastic burden to inflammatory and systemic outcomes."

The acidic pH inside the lysosome (vacuole in yeast) is essential for cellular content degradation, signaling, and autophagy. Defects in lysosome/vacuole acidification are a conserved hallmark of aging and age-related diseases. Traditionally, the lysosome/vacuole is thought to import free protons (H\u207a) from the surrounding neutral cytosol. Here, we uncovered a conserved lysosome/vacuole acidification mechanism from yeast to human involving lysosomal/vacuolar uptake of H+ pumped out by mitochondrial electron transport chain through mitochondria-lysosomes/vacuoles membrane contacts. Aging/senescence-associated disruption of mitochondria-lysosome/vacuole contacts causes lysosomal/vacuolar de-acidification, which can be reversed by either expressing an engineered linker to connect these two organelles or through an asymmetry-dependent rejuvenation process in daughter cells. Preserving lysosomal acidification in senescent human cells prevents the induction of major senescence-associated secretory phenotype factors and restores autophagic flux. These findings reshape our current understanding of the mechanisms underlying lysosomal/vacuolar (de-)acidification in both young and aged/senescent cells."

Herein, we developed a nano-delivery system, designated as CEL-TPP@siSurvivin/TDNP NPs, consisting of a self-assembled nanocore formed by triphenylphosphine (TPP)-modified celastrol (CEL) and siSurvivin, encapsulated within turmeric-derived nanoparticles (TDNPs), for effective tumor treatment through a combined chemotherapy and gene therapy approach. The TPP modification confers mitochondrial targeting capability to CEL, which acts combinedly with siSurvivin-mediated gene silencing to significantly enhance tumor cell apoptosis. Notably, once the NPs enter cells and become sequestered within lysosomes, they induce the upregulation of the V-ATPase subunits ATP6V1A/ATP6V1G1. It hyperactivates lysosomal proton pumps, driving excessive acidification of the lysosomal lumen, which in turn facilitates NPs escape and ultimately enhances the silencing efficiency of the delivered siSurvivin.

This study investigated the effects of polystyrene (PS) NPs on steatosis and fatty liver disease. PS-NP oral administration, in conjunction with a high-fat diet (HFD), synergistically exacerbated the symptoms of steatosis in mice, leading to increased alanine transaminase, aspartate aminotransferase, and cholesterol levels; no effects were observed with PS-NPs on a normal chow diet. Transcriptome analysis unveiled that PS-NPs interfered with actin organization, cell-cell adhesion, PPAR signaling, and lipid metabolism. In HepaRG cells, PS-NPs rapidly entered by inducing actin rearrangement, resulting in the formation of numerous small cytoplasmic vesicles. This treatment led to an augmented number of acidic organelles, leading to development and buildup of large vacuoles, indicative of enlarged pre-lysosomal and lysosomal compartments. PS-NP exposure hampered p62 degradation, leading to LC3B accumulation and decreased cathepsin B and D activity. Additionally, PS-NP exposure resulted in accumulation of lipid droplets and elevated expression of lipogenesis-, transport-, and storage-related genes.

PPD and PPT were used as membrane components to formulate anti-MUC5AC siRNA-loaded LNPs (designated as DLNPs and TLNPs). Flow cytometry and confocal laser scanning microscopy (CLSM) were employed to evaluate the cellular uptake and lysosomal escape of LNPs. An asthmatic mouse model was established to assess therapeutic effects of DLNPs and TLNPs through pathological section analysis and determination of inflammatory cytokine levels.

However, most existing research has focused on single exposure, which is not consistent with the actual exposure circumstance. In this study, single and co-exposure animal model were established. C57/BL6J mice were exposed to corn oil, 20\u00a0mg/kg PS-MPs, 200\u00a0mg/kg DEHP and PS-MPs\u00a0+\u00a0DEHP for 28 days. The HE staining showed more serious seminiferous epithelium disorganization in co-exposed mice, indicating that PS-MPs and DEHP co-exposure could aggravate testicular injury. Compared with control group, integrative analysis of transcriptomics and proteomics revealed that PPAR\u03b3 pathway played a crucial role in PS-MPs and DEHP co-exposure induced testis injury. In vitro, spermatocytes (GC-2) and leydig cells (TM3) were exposed to 50\u00a0\u03bcM MEHP, 10\u00a0mg/L PS-MPs and PS-MPs\u00a0+\u00a0MEHP for 48\u00a0h. Though PS-MPs and MEHP single exposure also triggered oxidative stress and PPAR pathway, the protein levels showed more remarkable difference in co-exposure group. Furthermore, co-exposure to PS-MPs and MEHP induced lysosomal membrane permeabilization (LMP), which significantly impaired lysosomal-mediated lipid degradation, thereby exacerbating lipid metabolism dysfunction in testicular cells. Treatment with N-Acetylcysteine (NAC) and knockdown of fatty acid-binding protein (FABP4) restored lipophagy flux and reduced lipid droplets deposition. Overall, co-exposure of PS-MPs and DEHP has synergistic toxic effect, inducing oxidative stress, PPAR\u03b3 activation and lipophagy blockage, finally resulting in unbalanced lipid metabolism and testicular damage."

Evidence confirms that nanoplastics and other environmental contaminants frequently induce lysosomal dysfunction, including alkalization, blockade of autophagic flux, and cathepsin inhibition. The proposal that AcNPs could be repurposed to mitigate nanoplastic-induced toxicity is mechanistically plausible given the convergent pathways of lysosomal impairment, although direct experimental evidence of AcNP application to nanoplastic-induced lysosomal damage in vivo is currently limited.\n\n### [ABSTRACT & REWRITTEN CLAIM]\nLysosomal integrity is a critical requirement for maintaining cellular homeostasis, particularly in the clearance of protein aggregates and lipid metabolism. Environmental contaminants, such as polystyrene nanoplastics, frequently target the endolysosomal system, causing pH elevation, cathepsin inhibition, and autophagic flux stagnation. Lysosome-acidifying nanoparticles (AcNPs), originally developed to treat lysosomal storage disorders and neurodegenerative conditions like Parkinson's disease, effectively reverse these lysosomal deficits. The synthesis of this evidence indicates that AcNPs may serve as a cross-disciplinary solution for restoring lysosomal function compromised by chronic nanoplastic exposure.\n\n### [INTRODUCTION & JUSTIFICATION]\nLysosomal acidification is a fundamental biological requirement for cellular health. As established in the literature, \"Defects in lysosome/vacuole acidification are a conserved hallmark of aging and age-related diseases.\" In the context of pathology, environmental factors significantly disrupt this process. Specifically, \"PS-NP exposure hampered p62 degradation, leading to LC3B accumulation and decreased cathepsin B and D activity.\" Furthermore, in neurological models, \"\u03b1-synuclein preformed fibrils (\u03b1-syn PFF) impair lysosomal acidification in microglia, leading to defective autophagic flux and disrupted \u03b1-syn degradation.\"\n\nTo counteract these failures, engineered nanomaterials have shown significant therapeutic potential. \"In vitro, AcNPs effectively restored lysosomal pH, enhanced autophagic clearance of \u03b1Syn, improved mitochondrial function, and rescued A30P \u03b1Syn-induced cytotoxicity.\" The mechanism of these particles is well-defined: \"These nanomaterials were developed to locally acidify impaired lysosomes and restore their degradative capacity.\" This restorative mechanism is highly relevant to industrial or environmental toxicity, as evidenced by studies where \"acidic nanoparticles rescued lysosomal acidification and relieved the degenerative changes\" in models of cellular stress. By restoring pH, these platforms re-enable the \"cathepsin B activity\" and \"active cathepsin D\" required for the degradation of sequestered toxic substances. Consequently, the repurposing of AcNPs to remediate lysosomal damage from nanoplastics represents a logical intersection of nanomedicine and toxicology.\n\n### [DISCUSSION: NOVEL & OVERLOOKED]\n* **Lysosomal Vulnerability:** Lysosomes are not merely digestive organelles but central metabolic hubs that are hyper-sensitive to the physical accumulation of non-degradable synthetic materials like nanoplastics.\n* **Convergent Mechanisms:** Whether the stress is caused by genetic mutations (e.g., GBA1) or environmental pollution (e.g., PS-NPs), the outcome is a remarkably consistent convergence on V-ATPase-mediated acidification failure.\n* **Active Restoration:** The ability of exogenous particles to restore lysosomal pH (re-acidification) suggests that the underlying biological machinery of the lysosome remains functional if the proton gradient is artificially maintained or recovered.\n* **Plastic-Biofilm Synergy:** Some plastics, particularly when associated with microbial contaminants (e.g., PET b001), cause significantly higher pro-inflammatory responses than the polymer alone, adding a layer of biological complexity to nanoplastic-induced lysosomal damage.\n* **Therapeutic Potential of Acidification:** Restoring acidification is sufficient to rescue autophagy flux in diverse contexts, including silkworm mutants and aging chondrocytes, proving its utility as a pan-stress resilience mechanism.\n* **Chirality Impacts:** Nanoscale chirality modulates biological response, with specific enantiomers of gold nanoparticles altering inflammatory pathways by modulating lysosomal acidification, demonstrating that physical properties dictate toxicological potential.\n* **Nutraceutical Intervention:** The link between lysosomal acidification and cardiac aging via nicotinamide adenine dinucleotide metabolism suggests that dietary or pharmacological restoration of v-ATPase function can reverse markers of senescence in aging tissues.\n\n### [EVIDENCE, METHODOLOGY & CITATIONS]\n1.

Weak basic small molecule compounds can diffuse into lysosomes and become protonated and trapped in a phenomenon known as lysosomal sequestration or trapping. Lysosomal trapping can influence unbound drug concentrations at the site of action, and consequently, drug responses. Drug accumulation in lysosomes may also impair phospholipid metabolism, leading to a severe side effect called drug-induced phospholipidosis. Current methods used to evaluate lysosomotropism are either indirect (high-throughput, but low sensitivity) or direct (sensitive but time- and labor-intensive). Moreover, no validated in-silico lysosomotropism prediction tools are publicly available. In this study, we developed a rapid fluorescence-based platform to screen for lysosomotropism and quantify lysosomal trapping propensity (IC50) of compounds in a standardized way. We also apply this method to various compound libraries including BBB (Blood-Brain Barrier) and protein degrader/PROTAC (Proteolysis-Targeting Chimera) compounds. This platform confirmed basic ECCS (Extended Clearance Classification System) class 2 compounds as lysosomotropic, and other ECCS class compounds as non-lysosomotropic. Collectively, this study provides measurable and efficient tools (in-silico & in-vitro) to identify and measure lysosomotropism, which can be applied by preclinical programs to decipher causes of intracellular accumulation.\n\nID: 42310725\nTitle: Targeting lysosomal pH restores mitochondrial quality control in GBA1-mutant Parkinson's disease.\nAbstract: Heterozygous mutations in the glucocerebrosidase gene (GBA1), which encodes the lysosomal enzyme \u03b2-glucocerebrosidase (GCase), are a genetic risk factor for Parkinson's disease (PD). The pathophysiological consequences of GBA1 mutations on dopaminergic neuronal function, especially their impact on lysosomal function, mitophagy, and mitochondrial bioenergetics, remain unclear. Fibroblasts and dopaminergic neurons generated from induced pluripotent stem cells (iPSCs) derived from patients with\u00a0GBA1-PD were used in the study. Live-cell imaging was performed to measure lysosomal acidification, protease activity, mitochondrial membrane potential, and mitophagy. Mitochondrial morphology and autophagic vesicles were examined using transmission electron microscopy. Oxygen consumption rate was measured by Seahorse assay. V-ATPase assembly was quantified using fluorescence lifetime imaging with F\u00f6rster resonance energy transfer (FLIM-FRET), and pharmacological interventions included rapamycin and acidic nanoparticles. GCase activity, lysosomal acidification, protease activity, mitophagy and mitochondrial bioenergetic function were all impaired in GBA1 mutant dopaminergic neurons. Mitochondria were fragmented, with reduced membrane potential and oxygen consumption. Mechanistic target of rapamycin complex 1 (MTORC1) was constitutively phosphorylated and FLIM-FRET measurements confirmed impairment of lysosomal V-ATPase assembly, which was reversed by rapamycin treatment. Rapamycin and lysosome-targeting acidic nanoparticles rescued lysosomal pH and restored mitophagy, mitochondrial membrane potential and mitochondrial oxidative phosphorylation complex level in the GBA1 mutant dopaminergic neurons. We revealed a novel mechanistic link between GBA1 mutations and mitochondrial dysfunction, as the disruption of V-ATPase assembly driven by MTORC1 activation impairs lysosomal acidification. This causes impairment of mitophagy, leading to mitochondrial dysfunction, undermining dopaminergic cell function and fate. Pharmacological intervention with rapamycin or acidic nanoparticles restores lysosomal pH and rescue mitochondrial function, representing a novel therapeutic approach for\u00a0GBA1-PD .\n\nID: 42176005\nTitle: Aptamer-conjugated nanoparticles: emerging nano-enabled platforms for rapid and sensitive detection of viral infections.\nAbstract: During the recent outbreak of SARS-CoV-2, the global healthcare system experienced firsthand the importance of accurate and rapid detection techniques in the containment of pandemic situations. Conventional viral detection techniques, although highly specific, often suffer from slow, labour-intensive workflows that limit their applicability for rapid diagnosis. Moreover, their reliability can be compromised by factors such as inadequate technical expertise and improper sample handling, potentially leading to erroneous results. When the global public health system is continuously struggling to control viral diseases like dengue, influenza, hepatitis B, and acquired immunodeficiency syndrome, cutting-edge nanotechnology and biosensor-enabled next-generation diagnostic platforms have shown improved analytical performances. Among these, aptamer-conjugated nanoparticles (ACNPs) have emerged as a promising nanosystem that integrates the high molecular recognition capability of aptamers with the unique physicochemical and optical properties of nanoparticles. Aptamers are short, single-stranded DNA, RNA, or peptide sequences that offer remarkable affinity and selectivity toward diverse viral biomarkers, including proteins, nucleic acids, and intact virions. Their conjugation with nanoparticles imparts superior stability, signal amplification, and biofunctional versatility under physiological conditions. These hybrid systems demonstrate substantial potential in biosensing, bioimaging, and providing enhanced diagnostic precision. This review aims to present the fundamental design principles of ACNP-based detection strategies and to highlight recent advances in viral diagnostics. Additionally, it underscores the underlying sensing mechanisms and analytical advantages, and discusses the current challenges associated with ACNP-enabled diagnostic platforms.\n\nID: 42105621\nTitle: Silica nanoparticles suppress porcine oocyte maturation via oxidative stress, metabolic dysfunction, and impaired cholesterol trafficking.\nAbstract: Silica nanoparticles (SiNPs), as common feed additives, are widely applied in livestock diets and pose potential risks to reproductive health owing to their tissue accumulation. In the present study, we explored the effects and underlying mechanisms of SiNPs exposure during in vitro maturation (IVM) of porcine oocytes. The results showed that SiNPs significantly suppress porcine oocyte maturation as evidenced by decreased first polar body (PB1) release rate. Notably, SiNPs significantly induced abnormal expansion of cumulus cells and impaired gap junction intercellular communication (GJIC), accompanied by decreased Connexin 43 (CX43) expression and aberrant F-actin structure. Furthermore, DCFH-DA staining showed that SiNPs significantly increased reactive oxygen species (ROS) levels and malondialdehyde (MDA) content, and decreased the mRNA levels of antioxidant-related genes, including SOD1, SOD2, CAT, GPX1, PRDX2, and NRF2. JC-1 staining showed that SiNPs significantly induced mitochondrial dysfunction via diminished mitochondrial membrane potential (\u0394\u03a8m) and aberrant distribution, and decreased the mRNA levels of energy metabolism-related genes, such as NOX4 and COX2. Additionally, SiNPs significantly disrupted lysosomal function and cholesterol trafficking and decreased the mRNA levels of LDLR, NPC1, NPC2, and LAMP2, leading to reduced free cholesterol levels and the mRNA levels of estrogen synthesis-related genes, including STAR, CYP19A1, and HSD-3\u03b2. Collectively, SiNPs suppress porcine oocyte maturation, at least partly, through oxidative stress, metabolic disruption, and impaired cholesterol trafficking.\n\nID: 42033266\nTitle: Lysosome-Acidifying Nanoparticles Rescue A30P \u03b1-Synuclein Induced Neuronal Death in Cellular and Drosophila Models of Parkinson's Disease.\nAbstract: Parkinson's disease (PD) is the second most common neurodegenerative disorder, affecting over 10 million people worldwide. It is characterized by the progressive loss of dopaminergic neurons in the substantia nigra and the accumulation of misfolded \u03b1-synuclein (\u03b1Syn) in intracellular inclusions known as Lewy bodies. Emerging evidence links \u03b1Syn accumulation to impaired lysosomal acidification and defective autophagy-lysosomal degradation, which are central to disease progression. To address this lysosomal dysfunction, we engineered a novel type of lysosome-targeted acidic nanoparticles (AcNPs) based on a biodegradable copolymer, poly(ethylene tetrafluorosuccinate-co-succinate) (PEFSU). These nanomaterials were developed to locally acidify impaired lysosomes and restore their degradative capacity. We evaluated their therapeutic potential in two familial PD models: SH-SY5Y neuroblastoma cells overexpressing A30P \u03b1Syn and A30P \u03b1Syn transgenic Drosophila melanogaster. In vitro, AcNPs effectively restored lysosomal pH, enhanced autophagic clearance of \u03b1Syn, improved mitochondrial function, and rescued A30P \u03b1Syn-induced cytotoxicity. In vivo, AcNPs treatment reduced \u03b1Syn burden, preserved dopaminergic neurons, and improved motor function in flies. This study demonstrates the first application of lysosome-acidifying polymeric nanoparticles in familial PD models and highlights the promise of rationally engineered pH-modulating nanomaterials as therapeutic agents for PD and other neurodegenerative diseases driven by lysosomal dysfunction and protein aggregation.\n\nID: 41933339\nTitle: Targeting the HDAC4-NHE6-endosomal pH axis restores amyloid-\u03b2 clearance and cognitive function in Alzheimer's disease mice.\nAbstract: Impaired clearance of amyloid-\u03b2 (A\u03b2) is a major pathological hallmark of Alzheimer's disease (AD). Although histone deacetylase (HDAC) inhibitors show therapeutic potential, their clinical translation for AD is hampered by poor blood brain barrier (BBB) penetration and an incomplete understanding of their mechanism in A\u03b2 clearance. Here, angiopep2-conjugated nanoparticles (SAHA@LIPO-ANG2) for efficient BBB translocation and delivery of the HDAC inhibitor vorinostat (SAHA) was developed and its underlying mechanisms were validated. Our result demonstrates that SAHA@LIPO-ANG2 potently inhibits HDAC4 nuclear translocation, which was identified as a key upstream event responsible for the transcriptional repression of sodium-hydrogen exchanger 6 (NHE6). Restoration of NHE6 expression rectifies endosomal hyperacidification, thereby rescuing the trafficking and plasma membrane expression of the A\u03b2 clearance receptor, low-density lipoprotein receptor-related protein 1 (LRP1). Furthermore, this HDAC4-NHE6-pH axis modulates the neuroimmune microenvironment to enhance A\u03b2 clearance through multiple synergistic mechanisms: it upregulates phagocytic receptors and recruit microglial to phagocytize A\u03b2 plaques, while concurrently reactivating autophagy-lysosomal function in astrocytes by increasing LAMP2 expression. Consequently, treatment with SAHA@LIPO-ANG2 in 5xFAD mice significantly reduced A\u03b2 burden, suppressed neuroinflammation, rescued synaptic loss, and ultimately reversed cognitive deficits. Our study not only elucidates a HDAC4-NHE6-pH regulatory axis in AD pathogenesis but also establishes a multifaceted nanotherapeutic strategy for restoring A\u03b2 homeostasis. Our findings may provide therapeutic strategies for treating amyloid-related diseases.\n\nID: 41912307\nTitle: Assessment of lysosomal drug sequestration and release using fluorescence microscopy.\nAbstract: Lysosomotropism refers to the ability of certain basic lipophilic compounds to accumulate in lysosomes via pH partitioning. Various drugs including anticancer agents are trapped in lysosomes, and this process can prevent such drugs from reaching their primary target, thereby limiting their effectiveness. Strategies aimed at preventing drug sequestration or inducing drug release from lysosomes have garnered considerable interest. Chloroquine is a widely used anti-malarial drug that triggers lysosome membrane permeabilization (LMP) to liberate sequestered drugs from these organelles. In this study, we first evaluate the lysosomotropism of various fluorescent anticancer agents in silico. Next, we outline a simple, fast and robust method for the visualization and quantification of their lysosomal sequestration and release by fluorescence microscopy. The method is used on live cells and consists of two steps:\u00a0(i) visualization of the compounds in lysosomes by analyzing their colocalization with a specific fluorescent lysosomal marker, and (ii) assessment of drug release from lysosomes. Furthermore, we present fluorescence microscopy protocols for monitoring LMP by analyzing the subcellular localization of LGALS3 (Galectin-3), which normally distributes diffusely in the cytoplasm but translocates into lysosomes upon LMP. This can be achieved on fixed cells by detecting endogenous LGALS3 with immunostaining or by the visualization of a transgenic LGALS3-mCherry fusion protein on live cells. Altogether, these methods facilitate qualitative and quantitative fluorescence imaging of lysosomal sequestration and liberation of lysosomotropic drugs.\n\nID: 41896932\nTitle: Overcoming lysosomal barrier via V-ATPase: an exosome-based co-delivery platform for combined chemo/RNAi therapy against breast cancer.\nAbstract: Overcoming the lysosomal entrapment of nanotherapeutics remains a pivotal challenge for efficient drug delivery. Herein, we developed a nano-delivery system, designated as CEL-TPP@siSurvivin/TDNP NPs, consisting of a self-assembled nanocore formed by triphenylphosphine (TPP)-modified celastrol (CEL) and siSurvivin, encapsulated within turmeric-derived nanoparticles (TDNPs), for effective tumor treatment through a combined chemotherapy and gene therapy approach. The TPP modification confers mitochondrial targeting capability to CEL, which acts combinedly with siSurvivin-mediated gene silencing to significantly enhance tumor cell apoptosis. Notably, once the NPs enter cells and become sequestered within lysosomes, they induce the upregulation of the V-ATPase subunits ATP6V1A/ATP6V1G1. It hyperactivates lysosomal proton pumps, driving excessive acidification of the lysosomal lumen, which in turn facilitates NPs escape and ultimately enhances the silencing efficiency of the delivered siSurvivin. Furthermore, in vivo studies validated that the nano-delivery system exhibits potent antitumor efficacy in a 4T1 murine breast cancer model while maintaining a favorable biosafety profile. This study presents a novel strategy to overcome the lysosomal escape challenge in nanomedicine, while also establishing an efficient and low-toxicity delivery platform for combined chemotherapy and gene therapy with promising clinical translation prospects.\n\nID: 41895019\nTitle: pH-gated aggregation of Cu-phycocyanin nanoparticles for precise induction of lysosomal membrane permeabilization and synchronized multimodal tumor cell death.\nAbstract: Lysosomal membrane permeabilization (LMP) mediated by pH-responsive materials has demonstrated considerable potential in tumor therapy. However, tumor cells exhibit a pronounced adaptive capacity to remodel lysosomal pH, thereby resisting LMP induction by pH-responsive materials and ultimately compromising therapeutic efficacy. To overcome this limitation, we engineered proton-driven \u03c0-\u03c0 stacked copper-phycocyanin nanoparticles (CuPC NPs) designed to selectively promote LMP in tumor cells through their aggregation within acidic lysosomes. Mechanistically, aggregated CuPC NPs directly engage the RIPK3/p-MLKL signaling axis to trigger LMP, thereby orchestrating the synergistic activation of necroptosis, ferroptosis, and cuproptosis. Due to the coordinated induction of multimodal cell death, these pH-responsive CuPC NPs effectively inhibit primary breast tumor growth and suppress pulmonary metastasis. Collectively, our study establishes a strategy for precise modulation of lysosomal function to enhance antitumor efficacy and provides valuable insights into the development of lysosome-targeted nanotherapeutics for tumor treatment.\n\nID: 41769917\nTitle: NIR-II Imaging-Guided Photothermal Activation of a TRPV4-Targeted Nanoplatform Delivering Cycloastragenol to Promote Microglia Reprogramming and \u03b1-Synuclein Clearance in Parkinson's Disease.\nAbstract: Current therapies for Parkinson's disease (PD) fail to concurrently address \u03b1-synuclein (\u03b1-syn) aggregation and microglia-mediated neuroinflammation. Herein, we engineer a near-infrared-II (NIR-II) phototheranostic nanoplatform, CAG/FD1080@MM-aTRPV4, for synergistic regulation of microglial function and real-time monitoring of PD pathology. We first encapsulated cycloastragenol (CAG), a bioactive compound derived from Astragalus, into liposomes. These liposomes were then fused with biomimetic microglial membrane-loaded FD1080 photothermal imaging agent, followed by modification with a transient receptor potential vanilloid 4 (TRPV4)-targeting antibody. In vitro studies using \u03b1-syn-treated cultured microglia and in vivo studies in an \u03b1-syn-overexpressing mouse model collectively demonstrate the efficacy of our strategy. It not only enables precise microglial delivery of CAG to reprogram metabolism but also sustains lysosomal function via photothermal activation of the TRPV4/CaMKK\u03b2/AMPK/mTOR pathway, ultimately enhancing phagocytosis. Importantly, the encapsulated FD1080 (for microglial tracking) and an anti-\u03b1-syn-conjugated indocyanine green (anti-\u03b1-syn-ICG) probe enable dual-modality NIR-II photoacoustic-fluorescence imaging, allowing real-time visualization of both microglial dynamics and \u03b1-syn clearance. This work pioneers a photothermal immunomodulation strategy using a Chinese herb-derived compound, presenting a versatile theranostic platform and novel mechanistic insights for microglia-targeted PD therapy.\n\nID: 41702478\nTitle: Antibody-nanoparticle conjugates for precision targeting of immunosuppressive tumor microenvironment.\nAbstract: Cancer continues to be a significant global health and socioeconomic issue, with an unequal mortality rate in low- and middle-income nations. The progression of tumors is influenced by both intrinsic changes within cancer cells and the tumor microenvironment (TME), which is a dynamic collection of stromal cells, immune infiltrates, extracellular matrix, and soluble mediators that together encourage immune suppression, angiogenesis, and resistance to treatment. Antibody-conjugated nanoparticles (ACNPs) combine antibody-mediated molecular recognition with nanoscale drug delivery systems to selectively target malignant cells and important components of the TME. In preclinical and early clinical studies, representative ACNP classes, including monoclonal antibodies or antibody fragments conjugated to liposomes, polymeric nanoparticles, metallic cores, or lipid-polymer hybrids, have exhibited enhanced tumor association and context-dependent intratumoral delivery, as well as the ability to modulate suppressive TME elements such as M2-like tumor-associated macrophages and cancer-associated fibroblasts. Nonetheless, clinical translation is impeded by significant biological and translational obstacles, such as tumor heterogeneity, restricted tissue penetration, swift elimination by the mononuclear phagocyte system, immunogenicity-associated safety concerns, and challenges in manufacturing and scaling up. In this paper, we critically examine ACNP design strategies, compare antibody formats and conjugation chemistries, and compile mechanistic evidence from in vitro, in vivo, and early clinical studies published up to 2025. We further investigate ACNP-based combination regimens targeting TME modulation and conclude by delineating translational priorities and practical design considerations necessary for achieving consistent therapeutic efficacy in heterogeneous human tumors.\n\nID: 41653942\nTitle: Engineering lysosomal collapse for cancer therapy: From mechanistic insights to nanotherapeutic innovations.\nAbstract: Lysosomes are markedly altered in tumor cells, exhibiting increased number and size, enhanced acidification, elevated cathepsin activity, and remodeled ion channel composition. These adaptations confer heightened degradative capacity and metabolic plasticity, supporting tumor survival, progression, and therapeutic resistance. Beyond their classical catabolic role, lysosomes function as central hubs for nutrient sensing, stress adaptation, and transcriptional regulation, making lysosomal integrity an emerging vulnerability in cancer therapy. This review aims to elucidate the therapeutic potential of inducing lysosomal collapse as an anticancer strategy, with a particular focus on recent nanotherapeutic approaches designed to precisely disrupt lysosomal function. This study systematically summarizes current knowledge on lysosomal structure and function in tumor cells and analyzes preclinical studies that exploit lysosomal destabilization for cancer treatment. Nanotherapeutic strategies targeting lysosomes are categorized according to their underlying mechanisms, including gas generation-mediated blasting, osmotic swelling, fiber-induced expansion, oxidative membrane damage, and direct phospholipid bilayer disruption. For each strategy, the design rationale, mechanistic basis, and representative experimental outcomes are critically evaluated. Accumulating evidence demonstrates that controlled lysosomal membrane permeabilization or rupture can effectively induce tumor cell death, reverse drug resistance, suppress metastasis, and alleviate immune evasion. Nanotherapeutic platforms enable spatially and temporally precise lysosomal disruption, enhancing antitumor efficacy while minimizing off-target toxicity. Comparative analysis reveals distinct advantages and limitations among different lysosome-targeting strategies, underscoring the importance of rational nanomaterial design. These advances establish lysosomes as central regulators of tumor biology and promising therapeutic \"death triggers\". Lysosome-targeted nanotherapeutics represent a powerful and versatile approach for overcoming major barriers in cancer treatment, offering new opportunities for precise, effective, and mechanism-driven anticancer interventions.\n\nID: 41643612\nTitle: Nano-bio interaction determines the early progression of lung cancer by reshaping\u00a0pulmonary epithelial microenvironment.\nAbstract: While the pulmonary microenvironment is a complex ecosystem comprising lung epithelial cells, immune cells, interstitial cells, and blood vessels, this study specifically focuses on the epithelium-centric niche to investigate the specific effects of SiNPs. This targeted microenvironment, centered on the interaction between epithelial components and their immediate surroundings, is intricately linked to the early progression and progression of lung cancer. Due to the prominent advances in nanotechnology recently, the interactions between nanoparticles and humans are inevitable. However, the role and precise mechanism of nano-bio interactions in PEM and their contributions to lung cancer are yet to be elucidated. In this study, we unexpectedly discovered that pulmonary exposure to silicon nanoparticles (SiNPs), a significant inhaled pollutant nanoparticle which was previously involved in inflammatory and fibrosis responses in the lung, intriguingly inhibited the early progression and metastasis of lung cancer in both in vitro and in vivo models. Mechanistically, SiNPs disrupted lysosomal function in lung epithelial cells, impaired the autophagosome-lysosome degradation pathway, and reduced Extracellular vesicles (EVs)-mediated communication between lung epithelial cells and lung cancer cells. An obvious decrease in EVs and their cargo, particularly miR-296-3p, within the tumor microenvironment heightened the susceptibility of lung cancer cells to ferroptosis. Our findings suggest that pulmonary exposure to SiNPs inhibits lung cancer early progression and metastasis, with the Atg5/EVs/miR-296-3p axis playing a critical role in this process. This study offers new insights into the mechanisms linking nano-bio interaction reshaped pulmonary epithelial microenvironment and lung cancer progression.\n\nID: 41621018\nTitle: Clinical advances and challenges of antibody-mediated targeted drug delivery in breast cancer therapeutics.\nAbstract: Breast cancer (BC) continues to present a universal health burden, and thus there is a need to develop antigen-targeted therapies with lower off-target toxicity and a greater therapeutic index. The antibody-mediated targeted drug delivery systems are especially antibody\u2013drug conjugates (ADCs) and antibody-conjugated nanoparticles (ACNPs) have become the game changers in the age of precision oncology. By taking advantage of the selectivity of monoclonal antibodies, these platforms preferentially target tumor-associated antigens (TAAs) including HER2, TROP-2, HER3 and LIV-1, which avoids off-target toxicity and overcomes drug resistance. This review presents a detailed discussion of the principles of design, mechanisms and clinical advancements of ADCs and ACNPs in the treatment of BC. Major advances are in the field of advanced linker technology, site selective conjugation techniques, and novel payloads that have potent antitumor effects. A number of new-generation ADCs have demonstrated promising clinical results, especially in HER2-positive and triple-negative forms of the BC. Moreover, nanocarrier-based drug delivery systems like trastuzumab-functionalized liposomes or polymeric nanoparticles are more advantageous in drug loading and release, as well as tumor penetration. In spite of this progress there are still several challenges including heterogeneity of tumor antigens, immunogenicity and off-target toxicity which hinder clinical translation. Bispecific antibodies, dual-payload ADCs, and patient-specific antigen profiling are some of the strategies under research to improve the precision of therapeutic treatment. With the application of molecular targeting and drug delivery innovation, the biology of antibody-mediated systems has enormous potential to transform the standard of treatment of BC and pave the way to customised medicine. Antigen selection, rational linker-payload design, and biomarker-directed patient stratification. In BC, ADC-led antibody-mediated delivery is setting therapeutic delivery action, and after all, toxicity management and mitigation of resistance are core clinical factors in success.\n\nID: 41533007\nTitle: PLGA nanoparticles restore acidic pH and degradative function to compromised lysosomes with Cy3-labeling providing enhanced tracking to lysosomes.\nAbstract: Lysosomal dysfunction and elevated lysosomal pH are hallmark features of age-related neurodegenerative diseases including age-related macular degeneration (AMD), Alzheimer's disease (AD), and Parkinson's disease (PD). Restoring lysosomal acidity is important for maintaining enzymatic degradation, preventing protein aggregation, and reducing cellular waste accumulation in degenerating tissues. Acidic nanoparticles represent a promising therapeutic strategy to normalize lysosomal pH; however, accurate monitoring of their delivery, retention, and dosage is critical for rigorous evaluation. To address this, we developed fluorescently labeled poly(d,l-lactide-co-glycolide) (PLGA) nanoparticles conjugated with Cyanine3 amine (Cy3). Nanoparticle uptake was systematically optimized, achieving over 90% delivery to lysosomes of induced pluripotent stem cell-derived retinal pigment epithelial (iPS-RPE) cells, although uptake rates varied among adjacent cells. Once internalized, nanoparticles demonstrated remarkable stability, with no detectable change in concentration, distribution, or size for at least 28 days. iPS-RPE cells exhibited higher nanoparticle internalization compared with the ARPE-19 cell line and optic nerve head astrocytes. The capacity of the nanoparticles to restore function to stressed lysosomes was confirmed by their ability to reacidify lysosomes, restore cathepsin B activity, and increase the levels of active cathepsin D. The nanoparticles also reduced the levels of LC3II in astrocytes treated with chloroquine, indicating that they can also restore autophagy rates. In summary, this study demonstrates the value of Cy3 labeling for enhanced nanoparticle tracking to lysosomes. The findings also identify PLGA nanoparticles as powerful tools for restoring degradative lysosomal function and autophagy in cells undergoing lysosomal stress.NEW & NOTEWORTHY Tools that restore acidic pH in compromised lysosomes can enhance autophagy and waste clearance in degenerative disorders characterized by excessive accumulation. Here, we describe the synthesis of lysosome-targeted nanoparticles composed of poly(d,l-lactide-co-glycolide) (PLGA) polymers covalently bound to the fluorescent dye Cyanine3 amine (Cy3). These Cy3-PLGA nanoparticles enable precise tracking of lysosomal delivery and demonstrate sustained long-term retention within lysosomes, supporting their potential for future applications aimed at restoring lysosomal pH in aging and degenerating diseases.\n\nID: 41452570\nTitle: Emerging Anti-Cancer and Repurposed Therapies for Overcoming Multidrug Resistance in Lung Cancer.\nAbstract: Multidrug resistance (MDR) still constitutes a significant barrier to the effective treatment of lung cancer and makes a significant contribution to the poor clinical results. MDR is explained by a set of mechanisms; increase of drug efflux, metabolism, increase of DNA repair potential, inhibition of apoptotic signals, mutation or post-translational modification of drug targets. These cell intrinsic mechanisms are even aggravated by tumour-microenvironment-induced factors, epigenetics dysregulation, survival of cancer stem cells and intratumour heterogeneity, which has made resistance highly adaptive and multifactorial. In order to address this complexity emerging therapeutic strategy is dual. The former element deals with new targeted agents which are able to counter an oncogene-mediated resistance. These include next-generation tyrosine kinase inhibitors (TKIs), KRAS12C inhibitors, bispecific antibodies including ivonescimab, and they all are specific to inhibit predominant signalling cascades that promote tumoral proliferation and resistance. The second element is drug repurposing whereby it exploits already established pharmacological drugs with already a clear safety record to attack non-oncogenic vulnerabilities linked with MDR. Pharmacological modulators of autophagy including statins, disulfiram, and lysosomotropic agents (e.g., chloroquine) target metabolic vulnerabilities such as mitochondrial bioenergetics and redox homeostasis. By mitigating oxidative stress and immune evasion, these compounds act as chemo sensitizers that potentiate the efficacy of tyrosine kinase inhibitors (TKIs) and immunotherapies, effectively overcoming adaptive drug resistance. Real-time monitoring of resistance evolution can be achieved with liquid biopsies, such as circulating tumor DNA and exosomal cargo, whereas MDR-related biomarkers can be used to stratify a patient. Analytical models that are built using artificial-intelligence also guide rational combination-therapy design and the chosen selection of treatments that are personalized. Also, inhalable nano formulations and targeted drug-delivery systems optimize the bioavailability of the formulation by pulmonary determination and ameliorates the systemic toxicity. A combination of these therapeutic approaches will provide a more accurate and flexible way of conquering MDR in lung cancer.\n\nID: 41350241\nTitle: Multistage Biobarrier-Adaptive Peptide Radiosensitizer with Low-Dose X-ray Augments Glioblastoma Radiotherapy via Destabilizing Lysosomal Homeostasis.\nAbstract: Glioblastoma (GBM) radiotherapy is hampered by intrinsic radioresistance. Current radiosensitizers face two unresolved hurdles: inability to dynamically traverse sequential physiological barriers of GBM and lack of multitargeted action against the pathways driving radioresistance. Here, we developed h-Pep-MTZ, a biobarrier-adaptive peptide-radiosensitizer addressing both. This system undergoes smart multistage transformations to overcome key delivery barriers: It first circulates as large, negatively charged nanoparticles to prolong plasma half-life; then converts to small, positively charged particles via tumor-overexpressed heparanase for deep tumor penetration; and finally assembles into long nanofibers triggered by lysosomal cathepsin B and acidity to extend tumor retention. Importantly, the nanofibers mechanically disrupt lysosomes, increasing lysosomal membrane permeability, inhibiting AKT activation, reducing autophagy, and impairing cytoskeletal integrity\u2500synergistically sensitizing tumors to radiation. This strategy combined with 6 Gy radiation achieved 82.5% tumor suppression in conventional U251 models and 60.4% in radioresistant U87 models, significantly outperforming the clinical radiosensitizer sodium glycididazole. This strategy provides a paradigm for overcoming GBM radioresistance by leveraging bioresponsive nanoscale transformations and lysosomal targeting.\n\nID: 41309670\nTitle: Thermal-exergetic analysis of hemispherical solar still enhanced with activated carbon nanoparticles synthesized from spent tea dust.\nAbstract: The growing problem of water scarcity worldwide necessitates the continuous development of various technologies to provide effective solutions. Among the various solutions for the desalination process, the solar still is the most prominent due to its cost-effectiveness and sustainable approach. The current experimental study proposes a new technique aimed at improving the functioning of hemispherical solar stills (HSS) by applying the carbonized nanoparticles (ACNPs) made from spent tea dust on the absorber plate. This method enhances the thermal conductivity and absorptivity of the surface. Incorporating ACNPs into the black paint results in increased thermal energy absorption, which raises the temperature of the absorber and water, thus increasing the yield of freshwater. To our knowledge, this is one of the first studies to incorporate waste-derived activated carbon nanoparticle coatings, examining their effects on the thermal and operational efficiency of HSS in realistic outdoor environments. This offers an inexpensive and easily adaptable upgrade to solar desalination systems. The research involved the fabrication of two identical solar stills: one featuring a conventional black surface coating, termed HSS, and the other incorporating activated carbon nanoparticles dispersed in black paint and applied on the absorber. The experimental results revealed that the thermal performance has significantly improved. The modified HSS recorded a peak absorber and water temperature of 74 and 72[Formula: see text]C, whereas the peak temperatures recorded from the conventional HSS were 71 and 69[Formula: see text]C, yielding average gains of 4.34% and 4.16% on absorber and water temperature, respectively. The improved heat transfer through evaporation leads to a higher temperature difference between the water and cover (20[Formula: see text]C (modified HSS) and 18 [Formula: see text]C (conventional HSS)), which results in an efficient condensation process. Moreover, there has been a substantial improvement in freshwater collection. The modified HSS produced a maximum hourly yield of 1.07 kg/[Formula: see text] and a cumulative daily yield of 5.06 kg/[Formula: see text], which is 33.67% higher than the conventional HSS yield of 3.72 kg/[Formula: see text]. This performance boost led to a substantial increase in efficiency. The daily thermal efficiency increased from 32.79% to 49.44%, and the daily exergy efficiency improved from 3.12% to 5.82%. An economic analysis demonstrated the viability of the modified system, with a payback period of 1.98 years and notable long-term savings. The use of spent tea dust for ACNP synthesis highlights the environmental and cost benefits of this approach. The findings highlight the potential of nano-enhanced coatings to enhance solar desalination technologies, offering an effective and sustainable solution for addressing global water challenges.\n\nID: 41247156\nTitle: Mesenchymal stem cell-derived nanovesicles coated PLGA nanoparticle (MSC-PLGA-NPs) remodel lysosomal function to clear pathological proteins in Alzheimer's disease models.\nAbstract: To develop a novel multifunctional nanoparticle platform by combining mesenchymal stem cell-derived nanovesicles (MSC-NVs) with poly(lactic-coglycolic acid) (PLGA) nanoparticles for Alzheimer's disease (AD) therapy. Mesenchymal stem cell-derived nanovesicle-poly(lactic-coglycolic acid) nanoparticles (MSC-PLGA-NPs) were prepared via sonication-loading. Blood-brain barrier (BBB) penetration was evaluated using in vitro transwell models and in vivo mouse models. Lysosomal function, autophagy, pathological protein clearance, and anti-inflammatory effects were assessed using various cellular and molecular biology techniques. MSC-PLGA-NPs demonstrated 2.3-fold higher BBB penetration efficiency compared to PLGA alone. In a chloroquine(CQ)-induced lysosomal injury model and mice model, they effectively restored lysosomal pH, enhanced autophagy (reducing LC3-II/I ratio by 0.4-fold and p62 expression by 52%), cleared amyloid precursor protein (APP) and phosphorylated tau (p-tau) proteins, and inhibited IL-6 and TNF-\u03b1 without hepatorenal toxicity. These results demonstrate that MSC-PLGA-NPs, a novel multifunctional nanoparticle platform, synergistically integrates the BBB penetration capability of MSC-NVs and the lysosomal acidification function of PLGA. The synergistic combination represents a pioneering \"delivery-repair-clearance\" integrated strategy for AD therapy. Offering significant advantages over single-component approaches, MSC-PLGA-NPs provide a promising preclinical candidate and new insight into lysosome-targeted nanomedicines for neurodegenerative diseases.\n\nID: 41193156\nTitle: Acute Care Nurse Practitioners and Healthy Work Environments in Critical Care.\nAbstract: Acute care nurse practitioners (ACNPs) play a crucial role in the intensive care units (ICUs) staffing by addressing physician shortages, enhancing care continuity, and improving outcomes. Their presence enriches the work environment by fostering interdisciplinary collaboration and streamlining communication. However, the factors influencing a healthy work environment for ACNPs are poorly understood. Recognizing their impact and addressing workplace challenges are essential for sustaining their well-being and optimizing their effectiveness in critical care. This article synthesizes evidence on ACNPs' role in the ICU and emphasizes the need for strategies to support their professional environment.\n\nID: 41069155\nTitle: Visual Whole-Process Monitoring Dynamic Phase Separation of Autophagic Lysosomes in Alzheimer's Disease by a Lysosome-Targeted pH-Activated Fluorescence Probe.\nAbstract: Although liquid-liquid phase separation (LLPS) of amyloid-\u03b2 (A\u03b2) aggregates is a critical driver of Alzheimer's disease (AD) progression, the role of lysosomal acidification defects remains poorly understood during this process. Herein, we successfully develop a synthetic strategy involving the construction of pH-activated probe backbones by the atom transfer radical polymerization technique with methacrylates with different substituents as monomers. Subsequently, a fluorescence probe is prepared by integrating hydrophobic aggregation-induced luminescence (AIE) fluorescence dyes and aggregation-induced bursting (ACQ) dyes into ACQ/AIE ratio imaging nanoparticles through covalent bonding and self-assembly techniques. Such AIE probe can monitor lysosomal acidification defects in AD and elucidate their role in A\u03b2 phase separation. Interestingly, our new findings reveal that A\u03b2 accumulation synergizes with lysosomal dysfunction (the pH value itself has not changed) to induce pathological LLPS, thereby providing a novel approach for phase modulation and attenuating AD progression. Taken together, our design concept provides a novel strategy to regulate phase separation, potentially reducing or delaying A\u03b2 aggregation and AD progression.\n\nID: 41060044\nTitle: The differential toxicity of three different oxidized nickel compound nanoparticles and the effects of particle surface ligands in mouse alveolar macrophages.\nAbstract: Nickel-compound engineered nanomaterials (Ni-X NP) have diverse applications, yet their continued use raises concerns for potential health impacts upon exposure. This study investigated 3 structurally distinct Ni-X-NP-pure NiO (NCZ), NiO@Ni(OH)2 (SIG), and Ni@NiO@Ni(OH)2 (AA)-to determine how core composition and surface functionalization contribute to bioactivity. Each Ni-X NP was modified with surface moieties (-OH, -COOH, and -CH3) to assess the efficacy of surface modifications in reducing bioactivity. Ni-X NP were thoroughly characterized for structure, surface chemistry, and Ni2+ ion release in simulated lysosomal fluid. Red blood cells (RBCs) were used to evaluate the hemolytic capabilities of the nanoparticles, and primary murine alveolar macrophages (AM), and murine ex vivo alveolar macrophages (mexAM) were used to assess uptake, cytotoxicity, IL-1\u03b2 release, and lysosomal membrane permeability (LMP). Results showed that NiO@Ni(OH)2 nanoparticles induced the greatest hemolysis in RBC, elicited the greatest IL-1\u03b2 response in AM and mexAM, and produced the most LMP in mexAM. The Ni@NiO@Ni(OH)2 nanoparticle released the most Ni2+ and caused profound reductions in AM cell viability but failed to cause RBC hemolysis or LMP. Pure NiO nanoparticles exhibited minimal bioactivity and low Ni2+ release. Surface modification with (-COOH) or (-CH3) effectively reduced bioactivity in LMP-mediated inflammation but had minimal effect on Ni2+-driven toxicity. This study reveals that Ni-X NP bioactivity depends on both core composition and surface chemistry, and that surface functionalization reduces inflammation only when lysosomal damage is the primary driver. These findings underscore the need for careful design and evaluation of engineered nanomaterials.\n\nID: 40997076\nTitle: Metal Ion-Enhanced Self-Assembly Properties of Amygdalin Extracted From Bitter Almond: Characterization and Potential Antiviral Applications.\nAbstract: Bitter almond is not only a widely used food, but also a classic tonic Chinese medicine, which mainly contains amygdalin (Amy), a bitter compound. Amy possesses multiple beneficial pharmacological activities, such as anticancer properties, blood sugar reduction, and immune enhancement. Based on previous research about the biological properties of Amy in different ion strength solutions, it was found to have certain self-assembly potential. In this study, a Ca2+ assisted self-assembly nanoparticle based on Amy is fabricated. The ability of metal ions to form Amy nanoparticles is explored with respect to the Amy concentrations, proportion of constituents, and temperature conditions. Dynamic light scattering (DLS) was employed for detection, revealing that the diameter of Amy-Ca2+ nanoparticles (ACNPs) ranges from 122 to 459\u00a0nm, with a polydispersity index (PDI) of 0.377. Subsequently, the assembly mechanism of ACNPs is investigated using ultraviolet-visible (UV-vis) spectra, Fourier transform infrared (FT-IR) spectra, and H nuclear magnetic resonance (H NMR) spectra. It is demonstrated that there is a hydrogen bonding interaction between Amy and Ca2+, and it is likely that the non-hydroxyl hydrogen at the position of the Amy sugar group interacts with Ca2+. Furthermore, the potential of ACNPs in an antivirus assay was validated by using respiratory syncytial virus (RSV) as an infection model. The results reveal that Amy exhibits anti-RSV activity to some degree, and when combined with calcium sulfate (CaSO4), another common food additive, it significantly enhances the anti-RSV effect. The enhanced anti-RSV effect may be attributed to the self-assembly phenomenon of Amy and Ca2+. In addition, in vitro hemolysis assays and cytotoxicity tests have demonstrated that ACNPs are biocompatible and safe. All in all, this study reveals the potential application of natural ingredient Amy in antivirus bioaction, highlighting its dual roles as a bioactive ingredient.\n\nID: 40972746\nTitle: Hybrid cell-membrane-coated biomimetic nanoparticles for targeted noninvasive intervention in early diabetic retinopathy.\nAbstract: Diabetic retinopathy (DR), a diabetes mellitus-induced ocular complication, demands non-invasive and effective early interventions to halt disease progression. Here, we developed biomimetic hybrid nanoparticles ([RBC-EC]-NPs) by coating fused membranes derived from red blood cells (RBC) and retinal endothelial cells (EC) on poly (lactic-co-glycolic acid) (PLGA) cores. Optimizing the membrane-to-PLGA ratio to 1:2 yielded stable nanoparticles that preserved critical membrane proteins, including CD47 (for immune evasion) and vascular endothelial cadherin (for endothelial targeting). The dual-coating strategy synergistically enhanced retinal endothelial targeting, suppressed pathological EC migration, and prolonged systemic circulation. In a STZ-induced diabetic rat model, intravenously administered [RBC-EC]-NPs selectively accumulated in retinal vasculature, significantly downregulating vascular endothelial growth factor expression, mitigating vascular leakage, thereby reducing formation of acellular capillary. Transcriptomic analysis revealed nanoparticle-mediated restoration of lysosomal function, lipid metabolism, and tumor necrosis factor-associated inflammatory pathways. Notably, systemic treatment also ameliorated dyslipidemia without inducing hematological or hepatic toxicity. Comprehensive biosafety evaluations confirmed the absence of acute tissue damage. Together, these findings demonstrated that [RBC-EC]-NPs could represent a potent and targeted nanotherapeutic platform for early-stage DR intervention, combining dual-cell membrane advantages with high biocompatibility. STATEMENT OF SIGNIFICANCE: Diabetic retinopathy (DR) remains a leading cause of blindness, and current treatments are largely invasive and limited to late stages. Here, we developed hybrid red blood cell-endothelial cell membrane-coated nanoparticles ([RBC-EC]-NPs) as a minimally invasive intravenous therapy. These biomimetic NPs uniquely combine endothelial targeting and immune evasion, enabling selective retinal vascular accumulation. Mechanistically, [RBC-EC]-NPs reduced VEGF overexpression, restored lysosomal-autophagy function, suppressed inflammation, and rebalanced lipid metabolism, thereby alleviating vascular leakage, preserving retinal microcirculation, and improving systemic lipid profiles in diabetic rat models. This study demonstrates the potential of [RBC-EC]-NPs as a safe, multifunctional therapeutic platform that targets the metabolic and vascular pathogenesis of early DR, offering a promising alternative to current intravitreal interventions.\n\nID: 40968501\nTitle: Phagosome Maturation in Macrophages is Enhanced by p38\u03b1 MAPK Signaling.\nAbstract: It is generally assumed that without active escape mechanisms, all cargo phagocytosed by macrophages eventually reaches lysosomes. Yet, the influence of specific ligands present on the cargo, like lipopolysaccharide (LPS), on phagosome maturation is unclear. Using sterile, non-immunogenic particles as model cargo phagocytosed by macrophages, this study showed\u00a0that in the absence of a specific ligand on the cargo, less than half the cargo-loaded phagosomes fuse with lysosomes. Quantification of phagosome maturation revealed that early events triggered by LPS-induced signaling enhance both cargo delivery to lysosomes and phagosome acidification rates. Specifically, it is demonstrated that stress-activated p38 alpha mitogen-activated protein kinase (p38 MAPK) enhances phagosome maturation under LPS-triggered signaling. Other signals known to activate p38 MAPK such as flagellin, IgG, and albumin, also enhance lysosomal delivery of phagocytosed cargo. The work indicates that phagosome maturation in macrophages is enhanced by specific ligands on the cargo, which activate cell surface receptors that signal via p38 MAPK.\n\nID: 40943372\nTitle: Acute Toxicity of Metal Oxide Nanoparticles-Role of Intracellular Localization In Vitro in Lung Epithelial Cells.\nAbstract: Endocytic uptake and lysosomal localization are suggested to be the key mechanisms underlying the toxicity of metal oxide nanoparticles (MONPs), with dissolution in the acidic milieu driving the response. In this study, we aimed to investigate if MONPs of varying solubility are similarly sequestered intracellularly, including in lysosomes and the role of the acidic lysosomal milieu on toxicity induced by copper oxide (CuO) nanoparticles (NPs), nickel oxide (NiO) NPs, aluminum oxide (Al2O3) NPs, and titanium dioxide (TiO2) NPs of varying solubility in FE1 lung epithelial cells. Mitsui-7 multi-walled carbon nanotubes (MWCNTs) served as contrasts against particles. Enhanced darkfield hyperspectral imaging (EDF-HSI) with fluorescence microscopy was used to determine their potential association with lysosomes. The v-ATPase inhibitor Bafilomycin A1 (BaFA1) was used to assess the role of lysosomal acidification on toxicity. The results showed co-localization of all MONPs with lysosomes, with insoluble TiO2 NPs showing the greatest co-localization. However, only acute toxicity induced by soluble CuO NPs was affected by the presence of BaFA1, showing a 14% improvement in relative survival. In addition, all MONPs were found to be associated with large actin aggregates; however, treatment with insoluble TiO2 NPs, but not soluble CuO NPs, impaired the organization of F-actin and \u03b1-tubulin. These results indicate that MONPs are sequestered similarly intracellularly; however, the nature or magnitude of their toxicity is not similarly impacted by it. Future studies involving a broader variety of NPs are needed to fully understand the role of differential sequestration of NPs on cellular toxicity.\n\nID: 40943340\nTitle: Natural Polysaccharide-Based Nanoparticles Enhance Intracellular Delivery and Cytotoxicity of Antrodia camphorata in Breast Cancer Cells.\nAbstract: Antrodia camphorata (AC), a medicinal fungus native to Taiwan, contains bioactive compounds such as triterpenoids with anticancer properties. However, their high lipophilicity results in poor aqueous solubility and limited bioavailability, restricting their therapeutic application. To address this issue, a nanoparticle-based delivery system was developed using chitosan, alginate, and hyaluronic acid to encapsulate AC extracts. AC-loaded nanoparticles (AC-NPs) with a particle size less than 100 nm improved drug solubility and facilitated intracellular accumulation. Assessment of cytotoxicity revealed that AC-NPs significantly and more effectively suppressed the growth of breast cancer cells than free AC extracts. After 72 h, IC50 values for MDA-MB-231 (triple-negative) and MCF-7 (estrogen receptor-positive) were 46.9 and 75.6 \u03bcg/mL, respectively, with greater sensitivity observed in MDA-MB-231 cells. AC-NPs exhibited minimal toxicity toward normal mammary epithelial cells (NMuMG), indicating good biocompatibility. Fluorescently labeled AC-NPs showed rapid, time-dependent uptake in both cancer cell lines. Particularly, MDA-MB-231 cells exhibited rapid internalization, whereas MCF-7 cells likely benefited from hyaluronic acid-mediated targeting of CD44 receptors. In conclusion, AC-NPs enhanced the solubility, cellular uptake, and anticancer efficacy of AC while maintaining biocompatibility, thereby suggesting their robust potential as nanocarrier platforms for breast cancer therapy.\n\nID: 40943214\nTitle: Inorganic Silica Nanoparticles Increase Lysosomal Biology and Protease Activity.\nAbstract: The use of nanoparticles has revolutionized drug delivery by enabling targeted and controlled therapeutic release. However, their interactions with intracellular organelles, particularly lysosomes, are not yet fully understood. This study delineates the differential effects of two widely used nanocarriers-mesoporous silica (MSNs) and albumin (ANPs) nanoparticles-on lysosomal biology, with a focus on the expression and activity of cathepsins (CtsB and CtsD), which are key proteases involved in protein degradation and maintaining cellular balance. These two types of nanoparticles, differing in their material and degradability, exhibit distinct behaviors inside the cell. We demonstrate that inorganic MSNs cause significant changes in lysosomal function by altering lysosomal content and cathepsin levels, without triggering lysosomal membrane permeabilization-a typical response to organic particle stress. In contrast, ANPs-which are susceptible to lysosomal cathepsin degradation-induce milder changes in cathepsin expression and maintain lysosomal integrity. Our results highlight that the composition of nanocarriers plays a pivotal role in modulating lysosomal protease activity and maintaining overall cellular homeostasis, highlighting the importance of these parameters in the rational design of drug delivery platforms.\n\nID: 40936032\nTitle: Carbon dot (CD)-based fluorescent probes for rapid and real-time tracking lysosomes movement and ATP monitoring in live cell.\nAbstract: The detection of lysosomal dysfunction and abnormal adenosine triphosphate (ATP) levels is crucial due to their roles in various cellular disorders and tumor progression, respectively. In this paper, carbon dot (CD)-based fluorescent probes (CDs-1 and CDs-2) with rapid lysosomal targeting and real-time lysosomal monitoring capability were designed. Through a hydrothermal method, the different nitrogen doping contents of CDs-1 and CDs-2 were controlled by varying the ethylenediamine content while the lysosome-targeting ability derived from their neutral red precursor was preserved. CDs-1 and CDs-2 rapid and effectively targeted lysosomes in both H1975 and 4T1 cells, with Pearson's colocalization coefficients of 0.94 and 0.88 (CDs-1) and 0.84 and 0.84 (CDs-2), closely matching the staining patterns of commercial lysosomal markers. CDs-1 demonstrated high specificity and sensitivity for ATP detection, displaying a linear detection range of 4-44 \u03bcM with a detection limit as low as 2.86 \u03bcM. CDs-1 enables\u00a0 monitoring of intracellular ATP level changes in the live cells under etoposide stimulation, while CDs-2 exhibited outstanding photostability and enabled real-time and long-term tracking of lysosomal movement. This study establishes CD-based fluorescent probes as valuable tools for investigating lysosomal function, with potential applications in cell biology research, disease mechanism studies, and drug screening platforms.\n\nID: 40845958\nTitle: Ridaifen derivatives function as potent lysosomotropic agents, depending on their basic side chains.\nAbstract: Autophagy plays a key role in cellular homeostasis, but dysregulated autophagy can lead to resistance to chemotherapeutic agents. The Ridaifen (RID) compound series comprises structural analogues of tamoxifen that exhibit more potent anticancer activity and have been implicated in modulating autophagy. Here, we investigated how the RID compounds interact with autophagy and explored the factors contributing to their enhanced cytotoxicity. We synthesized RID derivatives containing varying numbers of basic side chains and evaluated their intracellular behavior. We assessed cell viability using an MTT assay and determined lysosomal pH by flow cytometry. To visualize the subcellular distribution of the RID derivative, we employed a fluorescent dye\u2012conjugated form of the compound. Additionally, we monitored autophagic and apoptotic markers through immunoblotting. RID-B demonstrated potent lysosomal neutralization and inhibited autophagic flux near its half-maximal inhibitory concentration. This neutralization led to the accumulation of insoluble SQSTM1-containing aggregates, implicating proteotoxic stress in apoptosis. Confocal imaging revealed proton-dependent lysosomal localization of RID-B, followed by partial cytoplasmic translocation. Notably, co-treatment with bafilomycin A1 reduced RID-B\u2012induced apoptosis, underscoring lysosomal dysfunction initiated apoptotic signaling. Analyses across multiple RID derivatives showed a correlation among the number of basic side chains, lysosomal neutralization, and between lysosomal neutralization and cytotoxicity. Our findings indicate that basic side chains markedly enhance lysosomotropic behavior, enabling sustained autophagy inhibition and apoptosis induction. By revealing a strong link between lysosomal neutralization and proteotoxic cell death, the results suggest that modified tamoxifen analogues, such as RID-B, may offer a promising strategy to overcome autophagy-related drug resistance in cancer therapy.\n\nID: 40841709\nTitle: Programmed cell revival from imminent cell death enhances tissue repair and regeneration.\nAbstract: Cell recovery from near-death states is a critical yet poorly understood aspect of cell biology. Here, we describe a tightly-regulated programmed cell revival process after exposure of cells to cell death-inducing lysosomotropic agents, such as L-leucyl-L-leucine methyl ester (LLOMe). In the initial stage of cell recovery, we observe increased chromatin accessibility and upregulation of genes and pathways associated with embryonic development, regeneration, stemness, and inflammation. Subsequently, vital pathways governing metabolism, organelle biogenesis, membrane trafficking, transport, and cytoskeleton remodeling are activated, resulting in the complete renewal of cells. Consistent with the links of this transcriptional profile to tissue repair and regeneration, we found LLOMe to enhance the healing of skin wounds and corneal alkali burns in mice, promote hematopoietic progenitor/stem cell production in Drosophila melanogaster, induce tadpole tail regeneration in frogs, and mediate axon regeneration in Caenorhabditis elegans. Using both genetic and pharmacological approaches, we show NF-\u0138B signaling to be critical for both cell revival and regeneration. This study characterizes cell revival from near-death conditions as a programmed cell-intrinsic mechanism, which could be harnessed for therapeutic applications in regenerative medicine.\n\nID: 40836186\nTitle: Polymeric nanoparticle-mediated GBA1 gene therapy is neuroprotective in a preclinical model of Parkinson's disease.\nAbstract: Parkinson\u2019s disease (PD) is a debilitating neurodegenerative disorder characterized by the progressive loss of dopaminergic neurons in the substantia nigra (SN). It manifests with hallmark motor symptoms such as tremors, rigidity, and bradykinesia, as well as severe non-motor complications. Current therapies provide symptomatic relief but fail to halt or reverse neurodegeneration, emphasizing that a disease-modifying treatment option is sorely needed. Mutations in glucocerebrosidase 1 (GBA1) gene encoding GCase or mutation-free reduction of GCase activity disrupt lysosomal function and drive \u03b1-synuclein (\u03b1-syn) accumulation, thereby leading to neuronal and motor function loss. To this end, restoring GCase activity by GBA1 gene therapy would potentially benefit a broad PD population with or without the genetic risk by intervening with the natural trajectory of the disease. In this study, we implemented localized GBA1 gene therapy by intracranial convection-enhanced delivery of plasmid DNA comprising human GBA1 gene carried by engineered polymeric nanoparticles capable of mediating widespread neuronal transgene expression. In an \u03b1-syn preformed fibril (PFF)-induced mouse model of PD, our therapeutic strategy mediated robust human GBA1 transgene expression in the SN to significantly reduce \u03b1-syn aggregation/accumulation, preserve tyrosine hydroxylase-positive dopaminergic neurons, and mitigate neuroinflammation. Remarkably, motor deficits were markedly improved, as demonstrated by grip strength, pole, and open field tests. These findings underscore the transformative potential of our nanoparticle-based GBA1 gene therapy in addressing the limitations of current standard-of-care treatments. We expect that our therapeutic strategy, upon clinical development and translation, may contribute to shifting the therapeutic paradigm from the current symptomatic management toward disease modification to ultimately provide PD patients with a curative therapeutic option.\n\nID: 40824329\nTitle: Emerging trends in synthesis, characterization, and mechanism of action of antibody-drug and antibody-nanoparticle conjugates.\nAbstract: Antibody-drug conjugates (ADCs) and antibody-conjugated nanoparticles (ACNPs) are targeted therapies achieved by combining monoclonal antibodies (mAbs) with cytotoxic payloads or nanocarriers. ADCs consist of mAbs conjugated to the cytotoxic payloads via a linker, thus enabling tumor-specific delivery and reducing systemic toxicity. ACNPs add to this targeted therapeutic window by using nanoparticles. This conjugation promotes controlled drug release, higher drug-to-antibody ratios (DAR), and reduced off-target effects. ADCs exhibit precision in cell killing but face limitations such as antigen heterogeneity and Fc-mediated sequestration, whereas ACNPs enhance payload capacity and tumor penetration through their tunable physicochemical properties. ACNPs also facilitate multivalent binding by functionalizing multiple antibody molecules on their surface, improving target cell recognition and binding strength. Recent advancements include 14 FDA-approved ADCs and ACNPs in Phase I/II trials. A critical analysis of synthesis methods reveals that site-specific conjugation techniques enhance batch consistency, while characterization technologies, such as SEC-HPLC, LC-MS/MS, and SPR, address challenges related to DAR quantification and aggregation. Linker chemistry innovations, such as PEGylated maleimides balancing hydrophilicity and stability, are highlighted alongside emerging payloads. Despite progress, both platforms face translational hurdles: ADCs contend with manufacturing complexity and resistance mechanisms, while ACNPs require standardized in vitro models to predict in vivo behavior. This review emphasizes the significance of comparative efficacy studies and strategies for optimizing antibody density and orientation on nanoparticles. Together, these insights connect the gaps between synthesis, characterization, and therapeutic outcomes, steering the future development of targeted bioconjugates.\n\nID: 40782538\nTitle: Polystyrene nanoplastics-induced methuosis in brain microvascular endothelial cells: Rescue via ESCRT membrane repair system.\nAbstract: Nanoplastic pollution has emerged as a significant environmental concern, with increasing evidence suggesting that these nanoparticles can disrupt the blood-brain barrier (BBB) and accumulate in the brain, ultimately leading to neurological impairment. However, the underlying mechanism for the toxic effects of nanoplastics on the BBB remain poorly understood. In this study, we explored the toxic effects of polystyrene nanoplastic (PSNP) on brain microvascular endothelial cells (BMECs), one of the most critical components for maintaining BBB integrity. Our results revealed that PSNP specifically accumulate in the endolysosomal system following their internalization by BMECs. This accumulation disrupts lysosomal function and blocks endolysosomal pathways, ultimately triggering methuosis-a unique form of cell death characterized by extensive cytoplasmic vacuolization. Although the endosomal sorting complexes required for transport (ESCRT) system is naturally activated as a cellular defense mechanism, it is insufficient to repair PSNP-induced lysosomal membrane damage. By enhancing ESCRT activity, we effectively restored lysosomal function, thereby preventing cellular methuosis and preserving BBB integrity. Therefore, our findings provide crucial insights into the mechanisms underlying PSNP-induced BBB disruption by focusing on methuosis in endothelial cells. These insights hold important implications for environmental toxicology and public health in the context of global plastic pollution.\n\nID: 40763852\nTitle: Tunable structural, thermal and colloidal properties of anionic cellulose nanocrystals from oil palm biomass/metal oxide nanoparticles hybrid nanocomposites.\nAbstract: Cellulose nanocellulose (CNPs) is a virtual inexhaustible source of feedstock meeting the increasing demand for green, biocompatible products and ideal candidates for nanocomposites preparation for various application such as in packaging, biomedical devices, electronics, water treatment, energy storage devices and also in electronics application. However, integration of CNPs based nanocomposite into nanofluid application has received little attention which presents a clear research gap. As a result, this study used a bio-based functionalized sodium carboxymethyl nanocellulose (ACNPs) synthesis from oil palm empty fruit bunch (OPEFB) as a template, to synthesize hybrid nanocomposites with metal oxide (MONPs) at varying ACNP-to-MONP weight ratio. The present of COO- groups on the ACNPs act as template for coordinating metal precursors, promoting uniform MONP growth and strong interaction with ACNPs. Characterization techniques such as Fourier-transform infrared spectroscopy (FTIR), X-ray photoelectron spectroscopy (XPS), X-ray diffraction (XRD), and field emission scanning electron microscopy (FESEM) confirm the successful formation of MONPs on ACNPs by examine the morphology, distribution, chemical states, and bonding environments of the MONPs on the ACNPs. Besides this, thermogravimetric analysis (TGA) and zeta potential characterization are also conducted to assess the thermal and colloidal stability of the produced hybrid nanocomposites. Based on the result, hybrid nanocomposite with 1:1 weight ratio of ACNPs to MONPs was selected as an optimized weight ratio. In order to evaluate the performance and efficiency of the produced hybrid nanocomposite in nanofluid, thermal conductivity test was conducted using KD2Probe. The result indicating that the utilization of ACNPs as template for nanocomposite synthesis leads to a significant optimum enhancement in the thermal conductivity at temperature 45\u00a0\u00b0C, improving it by approximately 129, 100, 80 and 56\u00a0% after adding ACNPs/Al2O3, ACNPs/ZnO, ACNPs TiO2 and ACNPs/MgO based hybrid nanocomposite which making it a promising candidate for water based-heat transfer application.\n\nID: 40757003\nTitle: Developing Immunoniosomes (INs): Antibody and Fab conjugations of niosomal nanoparticles via UV-NBS and EDC/NHS chemistry for treating glioblastoma cells.\nAbstract: Antibody-conjugated nanoparticles (ACNPs), particularly immunoliposomes (ILs), have gained significant attention in cancer treatment due to their enhanced efficacy and superior tissue penetration. However, their high production costs and technical challenges underscore the need for more cost-effective alternatives. Niosomes, with their lower production costs, improved stability, and biocompatibility, have emerged as promising alternatives to liposomes in drug delivery. This study introduces immunoniosomes (INs), a novel class of antibody-conjugated niosomes, through two conjugation strategies: (i) UV-NBS, a site-specific covalent conjugation method utilizing an indole ring structure for moderate binding to the variable regions of antibodies and Fab fragments, and (ii) EDC/NHS chemistry, which conjugates antibodies to carboxylated niosomes via primary amines on lysine sidechains. Bevacizumab, a monoclonal antibody targeting VEGF and approved for the treatment of various cancers including glioblastoma multiforme (GBM), was used as a model therapeutic. Both Bevacizumab and its Fab fragment were conjugated to niosomes and evaluated in U87 glioma cells (overexpressing VEGF) and human umbilical vein endothelial cells (HUVECs) (representing normal VEGF expression). Physicochemical characterization of the conjugated niosomes confirmed hydrodynamic sizes ranging from 100 to 200\u00a0nm, neutral surface charge, and dispersity indices below 0.5-properties critical for effective cellular penetration and drug delivery. Cellular toxicity assays, conducted at a 10\u00d7 dilution from commonly reported concentrations, highlighted the role of the autocrine loop in U87 glioblastoma cells. Importantly, specific Nio-Fab conjugate formulations, created through both site-specific and randomized conjugation strategies, exhibited enhanced cytotoxicity toward U87 cells while sparing healthy endothelial HUVEC cells. In summary, this research establishes novel conjugation strategies to produce stable, site-specific, and randomized antibody-niosomal conjugates with enhanced half-life and selective toxicity against GBM cells. By offering an alternative route for antibody delivery through niosomal nanocarriers, these findings open new avenues for the development of more effective GBM therapeutics, warranting further non-clinical and clinical investigations.\n\nID: 40683250\nTitle: Reprogramming of endolysosomes for melanogenesis in BLOC-1-deficient melanocytes.\nAbstract: Photoprotective melanins in the skin are synthesized by epidermal melanocytes within specialized lysosome-related organelles called melanosomes. Melanosomes coexist with lysosomes; thus, melanocytes employ trafficking machineries that possess cell-type-specific functions to ensure correct cargo delivery to either the endolysosomal system or maturing melanosomes. Mutations in some of the protein complexes required for melanogenic cargo delivery, such as biogenesis of lysosome-related organelles complex 1 (BLOC-1), result in hypopigmentation due to mistrafficking of cargo to endolysosomes. We show that hypopigmented BLOC-1-deficient melanocytes retain melanogenic capacity that can be enhanced by treatment with cyclic adenosine monophosphate (cAMP)-elevating agents despite the mislocalization of melanogenic proteins. The melanin formed in BLOC-1-deficient melanocytes is not generated in melanosomes but rather within late endosomes/lysosomes to which some cargoes mislocalize. Although these organelles generally are acidic, a cohort of late endosomes/lysosomes have a sufficiently neutral pH to facilitate melanogenesis, perhaps due to mislocalized melanosomal transporters and melanogenic enzymes. Modulation of the pH of late endosomes/lysosomes by genetic manipulation or via treatment with lysosomotropic agents significantly enhances the melanin content of BLOC-1-deficient melanocytes. Our data suggest that upregulated expression of mistargeted cargoes leads to both increased tyrosinase expression and subsequent activity due to pH modulation facilitating the reprogramming of a subset of endolysosomes to replicate some functions of lysosome-related organelles.\n\nID: 40653518\nTitle: Thermal performance augmentation of double pass solar air collector using coated absorber with activated carbon derived from waste tea dust.\nAbstract: The extinction of fossil fuels to produce electrical energy and the demand for energy consumption is escalating every year. Several innovative approaches are developed to meet the present energy demand requirements, and one of the alternative and sustainable approaches is using renewable energy. In the present experimental investigation, a double pass SAC is fabricated, and the absorber plate is coated using activated carbon derived from the waste tea dust to augment the energy absorption rate. The thermal performance of the proposed system is compared by flowing the air through the rectangular cavity of the double pass SAC at different flow rates, namely 0.6, 1.2, and 1.8 kg/min. The output parameters, such as absorber temperature, heat transfer coefficient, air temperature leaving the duct, and thermal efficiency of the proposed double pass SAC, are compared with the conventional double pass SAC with black paint coating. The experimental studies revealed that the temperature of the absorber, air temperature leaving the duct, and thermal efficiencies are improved using activated carbon nanoparticles derived from the waste tea dust compared to the double pass SAC with black paint as a surface coating. Results demonstrated significant improvements: the activated carbon nanoparticle (ACNP)-coated absorber achieved an average thermal efficiency of 96.2% (vs. 77.8% for conventional) at 1.8 kg/min, with efficiency enhancements of 10.05-19.12% across flow rates. The exit air temperature and temperature difference between inlet/outlet increased by up to 10.71%, attributed to the ACNPs' superior solar absorption and heat transfer properties. Exergy efficiency also improved markedly, reaching 6.2% (vs. 3% for conventional) at 1.8 kg/min. This study highlights the dual benefit of repurposing agricultural waste into high-performance solar thermal materials while advancing sustainable energy solutions.\n\nID: 40651675\nTitle: Blend of polymeric nanoparticles-in-microneedle arrays: A potential transepidermal route for genistein for anti-melanoma activity.\nAbstract: The current research work aimed to fabricate and investigate the impact of Genistein (GIN) alginate-chitosan nanoparticles (ACNPs) into dissolving microneedle arrays for the treatment for melanoma. The natural compound, GIN demonstrates high lipophilicity (log P value\u00a0=\u00a03.04), low aqueous solubility (<1\u00a0\u00b5g/mL), which further limits the entry into skin and hinders its clinical application in healthcare. Therefore, to overcome the challenges, GIN encapsulated ACNPs were incorporated into dissolvable microneedle arrays of Povidone K90/PVA biodegradable matrix, to obtain GINACNPs@MNs and achieve controlled release profile at the tumor site. The surface morphology of GINACNPs@MNs confirmed successful development of pyramidal-shaped sharp, projections. The ATR-FTIR, DSC, analysis displayed the drug-polymeric interactions, and proved that the bioactive remained in the amorphous state in the microneedle matrix. The dissolving microneedle arrays, GINACNPs@MNs exhibited controlled release (75\u00a0\u00b1\u00a01.24\u00a0%) for 144\u00a0h with elevated drug content (97.00\u00a0\u00b1\u00a00.42\u00a0%). The GINACNPs@MNs showed high mechanical strength and strong insertion capabilities in the human skin simulant, Parafilm\u00ae M. In addition, the TEWL analysis confirmed reversible disruption, restoration of skin barrier without affecting the skin integrity. Moreover, the cytotoxic assay on A375 cells revealed IC50 value of 25.08\u00a0\u03bcg/mL for GINACNPs@MNs compared to 30.55\u00a0\u03bcg/mL for GIN, and displayed superior in-vitro cytotoxic activity. Subsequently, the in-vivo subcutaneous A375-tumor bearing mouse model, confirmed high antitumor efficacy of GINACNPs@MNs and displayed tumor volume of 1055.10\u00a0mm3 in comparison to untreated group (2584.50\u00a0mm3) after 18\u00a0days. Overall, the use of such novel, potential platform of GINACNPs@MNs offers minimally invasive approach for transepidermal delivery of GIN with high anti-melanoma activity.\n\nID: 42163812\nTitle: Self-Assembly of Stimuli-Responsive Peptide Enhances Therapeutics by Specifically Disrupting Hepatocellular Carcinoma Lysosomes In Vivo.\nAbstract: Lysosome sequestration or drug-triggered autophagic flux curtails antitumor drug potency in hepatocellular carcinoma (HCC) and can potentially be reversed with tumor cell-specific lysosomal disruption. Here, we demonstrate that a chimeric peptide (RS-FS), consisting of HCC-targeting RS and nanostructure-forming motifs (FS), self-assembles into nanospheres at neutral pH and transforms into nanofibers under acidic and reductive conditions. These nanofibers specifically localize to tumors and disrupt tumor cell lysosomes, thus enhancing doxorubicin's activity in human HCC cells in vitro and orthotopic HCC mice in vivo after RS-FS-doxorubicin treatment. Importantly, intravenous RS-FS potentiated oral Lenvatinib's antitumor activity up to 61-fold, and eradicated tumors in orthotopic HCC mice via HCC cell-specific lysosome disruption. Potent antitumor effects were also achieved with intravenous RS-FS and oral Epimedium brevicornu Maxim. -derived extracellular vesicles in orthotopic HCC mice, with markedly reduced tumor growth and increased cytotoxic T infiltration, in which RS-FS-mediated lysosome disruption promoted drug release and autophagic flux blockade. Our study demonstrates that RS-FS self-assembles into nanospheres or nanofibers in response to stimuli and enables tumor cell-specific lysosome disruption, resulting in enhanced drug release, autophagic flux blockade, and antitumor activities of diverse therapeutics in HCC mice, and thus provides a generalizable peptide adjuvant for sensitizing HCC-targeted therapeutics.\n\nID: 42146423\nTitle: Photoaged microplastics disrupt endothelial stretch-sensitive ion channels to impair calcium signaling and vascular integrity.\nAbstract: Plastic-derived micro- and nanoplastics are pervasive, but how environmentally aged particles affect vascular barriers is poorly understood. We hypothesized that photoaged plastics impair endothelial forcesensing, triggering gut-brain-heart barrier failure. Ultraviolet (UV) exposure converted pristine nanoplastics into oxidized, irregular photoaged microplastic aggregates (> 1.2 \u03bcm). In human aortic endothelial cells, photoaged particles increased membrane stiffness and activated transcriptional programs linked to permeability, junction disruption, inflammation, and cytoskeletal remodeling. Mechanistically, photoaged particles selectively inhibited Piezo1-mediated Ca2+ signaling and downstream Notch activity without changing PIEZO1 expression, and endothelial CRISPR inhibition of PIEZO1 recapitulated these effects. In zebrafish, photoaged plastic exposure increased gut-vascular permeability and systemic spread with brain and heart accumulation, accompanied by reduced neurovascular and myocardial Ca2+ signals, depressed cardiac contractility, and abnormal locomotor behavior. Thus, photoaged plastics compromise vascular barriers through disrupted endothelial Piezo1-Notch mechanotransduction.\n\nID: 42003420\nTitle: Inhalable Polymeric Nanoparticle Vaccine for Lysosome-Targeting Co-Delivery of Antigen and Adjuvant With Enhanced Immunoprotection.\nAbstract: Conventional subunit vaccines, typically formulated as a simple antigen and adjuvant mixture, suffer from premature clearance and poor synchronization of antigen and adjuvant, resulting in suboptimal immune activation. Here, we develop an amphipathic polymer, YAXA, featuring acid-labile imine bonds for pH-responsive degradation and terminal NHS-activated esters for covalent conjugation of protective antigen. Through hydrophilic-hydrophobic co-assembly with the hydrophobic TLR7 agonist 3M-052, followed by antigen conjugation, YAXA forms an inhalable nanoparticle vaccine, YM3.7, in which the antigen is displayed on the hydrophilic surface while the adjuvant is encapsulated in the hydrophobic core. Following aerosolized intratracheal inoculation into the lung, YM3.7 is efficiently internalized by antigen-presenting cells and trafficked into the lysosome, where acidic conditions trigger its dissociation and co-release of antigen and adjuvant. This lysosome-targeted, spatiotemporally synchronized delivery couples antigen presentation with TLR7/NF-\u03baB activation, driving robust immune responses, including antigen-presenting cell maturation, germinal center formation, systemic and lung-resident B/T cell response, and IgG/sIgA production. In lethal pneumonia models induced by Pseudomonas aeruginosa or Staphylococcus aureus, YM3.7 markedly improves survival over a conventional antigen and adjuvant mixture. This research establishes a paradigm for developing next-generation inhalable nanoparticle vaccines, capable of spatiotemporally coordinating innate immunity, humoral immunity, mucosal immunity, and cell-mediated immunity to provide enhanced immunoprotection.\n\nID: 42000504\nTitle: Polystyrene microplastics disrupt the blood-testis barrier via CEBPB-driven lysosomal autophagy and induce ferroptosis-like injury in human sperm, compromising embryo development.\nAbstract: Environmental exposure to microplastics, especially polystyrene microplastics (PS-MPs), poses growing concerns for male reproductive health. In this study, we demonstrate that PS-MPs internalize into Sertoli cells, triggering CEBPB-mediated lysosomal hyperactivation and the degradation of tight junction proteins, thereby impairing the structural integrity of the blood-testis barrier (BTB). Concurrently, PS-MPs accumulate in mature human sperm, damaging mitochondrial ultrastructure and inducing ROS-driven lipid peroxidation and ferroptosis-like injury. These alterations result in reductions in motility, DNA integrity, and early embryonic development following intracytoplasmic sperm injection (ICSI). Crucially, the antioxidant N-acetylcysteine (NAC) rescued sperm functional metrics and restored embryo quality. These findings reveal dual cellular pathways, disruption of both the barrier and sperm mitochondrial integrity, by which environmental PS-MPs impair male fertility. The study highlights NAC as a promising intervention and identifies chloroquine as a potent modulator of lysosome-mediated BTB disruption. The environmental relevance of PS-MPs and their mechanistic impact on human reproductive health underscore the urgent need for strategies to reduce pre-fertilization microplastic exposure.\n\nID: 41851278\nTitle: Glycine alleviates ovarian granulosa cell ferroptosis induced by ER\u03b1-mediated internalization of polystyrene microplastics.\nAbstract: Polystyrene microplastics (PSs), pervasive environmental contaminants found in food and human tissues, pose an emerging threat to reproductive health. Elucidating the mechanisms underlying PS-induced toxicity and identifying effective interventions to mitigate adverse effects are therefore critically important. Here, our findings demonstrated that PS exposure in 5-week-old female SPF Kunming mice leads to decreased serum hormone levels and reduced transzonal projections. Furthermore, this study revealed that PS-induced ferroptosis in ovarian granulosa cells. Mechanistically, ER\u03b1-mediated PS internalization led to activation of the YAP1-ACSL4 signalling and subsequent lipid peroxidation. Moreover, we demonstrated that glycine effectively alleviate PS-induced ferroptosis by modulating lysosome-dependent ferritin degradation in a PAT1-dependent manner, thereby restoring iron homeostasis. Taken together, these findings revealed that PS exposure triggers ACSL4 overexpression and iron overload in ovarian granulosa cells, whereas glycine restored iron homeostasis via lysosome-mediated ferritinophagy. This study provides critical insights into the reproductive health risks of PS exposure and offers a potential intervention strategy.\n\nID: 41702167\nTitle: Lipid metabolic dysregulation: A novel developmental toxicity pathway of aged nanoplastics via inhibition of lipophagy in zebrafish.\nAbstract: The widespread occurrence of micro/nanoplastics (MNPs) in ecosystems poses significant environmental challenges. Although environmentally aged MNPs predominate, their developmental toxicity remains poorly understood. We demonstrate that both pristine and aged polystyrene nanoplastics (PSNPs) induce abnormal lipid accumulation and impair early development in zebrafish larvae. Lipidomics revealed aged PSNPs significantly increased triglycerides via disrupted glycerophospholipid metabolism. Mechanistically, aged PSNPs did not alter LC3-II/LC3-I ratios but upregulated RAB7 and p62 while downregulating lysosomal biogenesis regulator TFEB. They also reduced ATG5, essential for autophagosome formation via LC3 lipidation. These molecular alterations, together with lysosomal inhibition assays, functionally support lysosomal dysfunction as a key constraint on lipophagy. This impairment inhibits lipid utilization, promotes accumulation, and disrupts development. Critically, aged PSNPs caused stronger disruption than pristine particles despite both interfering with lipophagy. Our study provides mechanistic insights into the developmental toxicity of UV-aged PSNPs in zebrafish, highlighting the importance of considering aging-related changes in nanoplastic risk evaluation. SYNOPSIS: Aged nanoplastics exacerbate developmental toxicity in zebrafish by suppressing lipophagy to drive lipid accumulation, underscoring ecological risks in aquatic systems.\n\nID: 41643617\nTitle: Early-life exposure to polystyrene nanoplastics at ambient doses induces neurotoxicity via mTOR-mediated autophagy-lysosomal dysfunction and proteostasis imbalance.\nAbstract: Nanoplastics are an emerging global environmental concern, with increasing evidence of their neurotoxic effects. Recent findings suggest that abnormal aggregation of pathogenic proteins within the nervous system may contribute to the neurotoxicity induced by nanoplastics, yet the molecular mechanisms regulating this pathological cascade remain unclear. Here, we used immature mice as an experimental model to represent infants and young children who are at higher risk of nanoplastics exposure, to elucidate the molecular mechanisms underlying neurotoxicity induced by exposure to polystyrene nanoplastics (PS-NPs) during early life. The results showed that environmentally relevant doses of PS-NPs penetrated the brains of immature mice and induced behavioral and emotional disorders. Proteomic analysis identified the mTOR signaling pathway as a candidate pathway responding to PS-NPs exposure in the immature mouse brain. Rapamycin intervention and quantitative validation further demonstrated that PS-NPs exposure upregulated mTOR signaling, thereby leading to lysosomal dysfunction and a blockade of autophagic flux, which in turn disrupted proteostasis and ultimately caused neurotoxicity. Furthermore, treatment with sodium 4-phenylbutyrate (4-PBA) confirmed that proteostasis imbalance, characterized by activation of the unfolded protein response, was a direct driver of this neurotoxicity. Notably, both rapamycin and 4-PBA treatments alleviated neurotoxicity resulting from PS-NPs exposure by restoring proteostasis. Together, these findings highlight dysregulation of the autophagy-lysosome pathway mediated by mTOR as a central mechanism of PS-NPs-induced neurotoxicity in immature mice and suggest lysosomal regulation for proteostasis remodeling as a prospective therapeutic strategy against neurological hazards related to nanoplastics.\n\nID: 41455227\nTitle: Arachidonic acid reverses microplastic-induced macrophage dysfunction in teleost fish.\nAbstract: Microplastic pollution poses a significant threat to aquaculture by compromising fish immunity, particularly macrophage function. This study investigated the impact of polystyrene microplastics (PS) on Nile tilapia (Oreochromis niloticus) macrophages and explored metabolic interventions to reverse PS-induced damage. PS exposure increased tilapia susceptibility to Streptococcus agalactiae infection, reducing fish survival. PS accumulated in head kidney macrophages, impairing phagocytosis, altering cytokine expression, elevating oxidative stress and malondialdehyde levels, and suppressing T-cell proliferation. Transcriptomics revealed PS dysregulated lysosomal pathways, reducing lysosomal membrane permeability and bacterial killing capacity. Metabolomic screening identified arachidonic acid (AA) as the most significantly suppressed metabolite in PS-exposed macrophages. Exogenous AA administration restored macrophage function including phagocytosis, cytokine expression, oxidative stress, enhanced lysosomal integrity, improved bactericidal activity, and increased survival during S. agalactiae challenge in PS-exposed fish. AA also reversed PS-induced transcriptional dysregulation of lysosomal genes. These results demonstrate that AA rectifies PS-induced macrophage dysfunction and lysosomal impairment, supporting its potential as a dietary supplement to mitigate microplastic immunotoxicity in aquaculture.\n\nID: 41373713\nTitle: Albumin-Phthalocyanine Nanoconjugates as Platforms for Enhanced Photodynamic Cancer Therapy.\nAbstract: This study investigates the enhancement of photodynamic therapy (PDT) efficacy through the encapsulation of platinum phthalocyanine (Pc) in albumin nanoparticles (ANP). Encapsulation of Pc in ANP) significantly enhances its biological effects in photodynamic therapy by increasing cellular uptake through receptor-mediated endocytosis and promoting lysosomal accumulation. This leads to marked lysosomal stress and regulated necrotic cell death pathway, while free Pc causes moderate oxidative stress with reversible apoptosis and autophagy. The enhanced phototoxicity of encapsulated Pc was evident across multiple cancer cell lines, especially aggressive phenotypes, whereas resistant lines showed lower sensitivity likely due to efficient ROS scavenging. Despite improved initial uptake, rapid lysosomal release and extracellular extrusion of Pc limit long-term intracellular retention. Morphological and gene expression analyses confirmed distinct cell death mechanisms between free and encapsulated Pc, underscoring the critical role of nanocarrier-mediated delivery in modulating oxidative stress and cellular response. These findings highlight the importance of nanoparticle design in optimizing PDT efficacy by effectively triggering necrotic cell death pathway.\n\nID: 41093227\nTitle: Hitchhikers in bivalve immune system: Mixed microplastics and nanoplastics triggers hemocyte autophagy.\nAbstract: Natural microplastic and nanoplastics (MNPs) mixtures generally consist of multiple sizes, but how their co-existence influences the immune system of aquatic organisms remains elusive. Here, we quantitatively tracked and demonstrated that such heterogeneity dynamically reshaped bivalve hemocyte burden in non-additive modes with subpopulation-specific consequences for immune function. Kinetic modeling revealed distinct internalization patterns and selectivity among hemocyte subpopulations, driven by particle proportions and uptake dynamics. Granulocytes displayed indiscriminate capacity for MNP internalization, maintaining high uptake efficiency across varying particle compositions. In contrast, semigranulocytes showed selective internalization behavior sensitive to particle size distributions, facilitating preferential uptake shifts as nanoparticle proportions varied. Mechanistically, large NPs accelerated the internalization of smaller NPs via a hitchhiking effect but simultaneously competed for intracellular processing pathways, limiting maximal uptake. Notably, co-exposure with smaller NPs significantly enhanced and accelerated MPs internalization, leading to intracellular overload with severe lysosomal damage and mitochondrial impairment. These disruptions potentially triggered mitochondria-lysosome crosstalk and autophagy, particularly pronounced in semigranulocytes. Ultimately, the combined presence of multiple particle sizes resulted in cascading impairment of hemocyte phagocytic capacity than exposure to individual particles alone, highlighting particle-size interactions as critical determinants of immunotoxicity. Our findings underscored how coordinated disposal of hemocyte subpopulations influenced the mixed-size plastic clearance, providing new insight on the health risks posed by MNPs to marine organisms.\n\nID: 41038372\nTitle: Lysosomal dependent transcytosis of polystyrene nanoplastics within macrophages.\nAbstract: As emerging pollutants, nanoplastics (NPs) have emerged as significant environmental pollutants with potential health risks and have been largely investigated owing to their distinctive physicochemical properties and ubiquitous environmental distribution. However, research on the intracellular complete migration of NPs is limited, particularly with respect to exocytosis. Here, we exposed human macrophages to polystyrene nanoplastics (PS-NPs) and observed that PS-NPs induced the accumulation of lysosomes within the cells and lead to an increase in their contents. Additionally, PS-NPs co-localized with lysosomes and triggered lysosomal activation. Using a previously established method for PS-NPs adsorption to intracellular proteins and employing proteomic and bioinformatic approaches, we confirmed that after entering the cell, PS-NPs predominantly adsorbed proteins related to the lysosomal pathway, and stably adsorbed the key lysosomal protein cathepsin D (CTSD). Further studies identified that PS-NPs induced lysosomal exocytosis, during which the lysosomal-specific mature-CTSD adsorbed onto PS-NPs and was co-released from the cell. This process was mediated by Ca2+. In summary, this study elucidated the lysosome-dependent transcytosis of PS-NPs and established a novel method for verifying lysosomal exocytosis using mature-CTSD as a marker.\n\nID: 40963485\nTitle: Shedding Light on the Cellular Uptake Mechanisms of Bioactive Glass Nanoparticles as Controlled Intracellular Delivery Platforms: A Review of the Recent Literature.\nAbstract: Recent advancements in nanotechnology have enabled the synthesis of bioactive glass nanoparticles (BGNs), promising multifunctional platforms for the simultaneous delivery of therapeutic ions and biomolecules. However, the intracellular efficiency of BGNs is limited by the internalization mechanism, further dictating the intracellular trafficking and fate. Following a general overview of the main uptake pathways of nanoparticles and the subsequent intracellular localization, a comprehensive analysis of the BGNs' internalization process is presented. Key findings reveal that the BGNs are mainly internalized by active transport mechanisms and are entrapped in endosomes/lysosomes, limiting their ability to exert their full intracellular therapeutic potential. Existing studies in the literature provide valuable data to correlate the uptake process with the intracellular BGN localization, but there is limited research on the fate of BGNs and the released ions once entrapped in intracellular vesicles. Therefore, in the last part, future strategies to either escape the endosome or use the lysosomal degradation as a mechanism for controlled intracellular ion release with implications for targeted modulation of cell behavior are discussed. Going beyond BGNs, this review highlights the need of understanding better the dynamically transforming degradable nanoparticles - an essential step toward achieving their full intracellular therapeutic potential.\n\nID: 40954128\nTitle: Endolysosomal Sequestration Effects Controlled Release of BRAF Paradox Breaker Nanoparticles.\nAbstract: BRAF remains one of the most important therapeutic targets in cancer, but BRAF inhibitors can cause \"paradoxical\" pathway activation and drug resistance through RAF dimerization. A clinical \"paradox breaker\" inhibitor of BRAF monomers and dimers can potentially evade drug resistance. However, patients are required to receive a high oral daily drug dose to achieve the target therapeutic window. Co-administration of a cytochrome P450 blocker can improve drug exposure, but the combination can lead to drug-drug interactions. We investigated delivery via fucoidan-based nanocarriers to improve pharmacologic properties. We found that the nanoparticles extended BRAF inhibition in cancer cells due to sequestration into endolysosomes, followed by controlled release from a lysosomal depot. Following intraperitoneal administration, nanoparticles improved drug pharmacokinetics in vivo without inhibiting cytochrome P450 and also resulted in substantial improvements in antitumor efficacy. This work describes a general nanotherapeutic strategy to improve the pharmacologic properties of drugs via intracellular depot formation.\n\nID: 40939049\nTitle: Dual-Enzyme Encapsulated Porous Nanocapsules for Lysosome-Targeted, Hypoxia-Amplified Cancer Therapy.\nAbstract: Glucose oxidase (GOx) catalyzes the oxidation of glucose to gluconic acid and hydrogen peroxide (H2O2), while horseradish peroxidase (HRP) converts H2O2 into cytotoxic hydroxyl radicals (\u2022OH) under acidic conditions, such as those in lysosomes. Harnessing this tandem enzymatic activity offers a promising strategy to exacerbate tumor hypoxia and induce cancer cell death. Herein, we report the synthesis of hollow, porous organic nanocapsules (HPOCs; average diameter \u223c145 nm, wall thickness \u223c11 nm) via an inverse mini-emulsion technique using functionalized diamine and tetracarbaldehyde precursors. These nanocapsules coencapsulate GOx and HRP while acting as size-exclusion membranes, allowing selective diffusion of small molecules while retaining the enzymes. Confocal studies with BODIPY-labeled GOx and Cy5-labeled HRP ensure the encapsulation of both enzymes within the HPOCs and are found to be localized in the lysosome. The HPOCs exhibit excellent biocompatibility and, under hypoxic conditions, trigger substantial cancer cell apoptosis (\u223c75% cell death) and G2/M cell cycle arrest. Control nanocapsules lacking either or both enzymes show negligible therapeutic effect, underscoring the synergistic mechanism. This work presents a proof-of-concept for two-enzyme-loaded HPOCs as an effective platform for synergistic, hypoxia-amplified cancer therapy.\n\nID: 40866363\nTitle: Multifunctional D-Type Peptide Dendrimer-Based Nanocarriers Enabling Inherent Autophagy Modulation and Lysosomal Escape for Breast Tumor Therapy.\nAbstract: Chemotherapy is often limited by its low efficacy and severe side effects. Autophagy acts as a double-edged sword where high levels can promote cancer cell death, while low levels induced by chemotherapy can reduce therapeutic effects. Herein, we designed a multifunctional D-type peptide dendrimer as a drug delivery system for chemotherapeutic agents. This nanocarrier is designed to significantly reduce the toxic side effects of the drug and, upon internalization into cancer cells, utilizes the dendrimer terminals modified with histidine to achieve efficient lysosomal escape, thereby rapidly releasing the payload and enhancing therapeutic efficiency. We employed transmission electron microscopy (TEM) and Western blot (WB) assays to assess the stronger autophagy-inducing potential of the D-type dendrimers compared with L-type and free chemotherapeutics. Beyond its role as a carrier, the D-type dendrimers further synergize with the encapsulated drug to trigger enhanced autophagy, aiming to enhance therapeutic efficiency. This \"Squeezing every ounce of potential\" strategy fully leverages the capabilities of the D-type peptide dendrimers, thereby addressing the existing challenges in chemotherapy treatment. This approach suggests a promising therapeutic strategy for the application of chemotherapy.\n\nID: 40768614\nTitle: Engineered Stem Cell Membrane-Coated Nanodrugs for Targeted Therapy of Alzheimer's Disease.\nAbstract: The pathological complexity of Alzheimer's disease (AD) necessitates the development of efficient nanomedicine delivery systems. Nanoparticles are considered promising therapeutic candidates for AD owing to their drug-loading capacity. This study introduces an engineered cell membrane coating strategy to enhance nanoparticle functionality in targeting efficiency and susceptivity to immune clearance. We developed an engineered biomimetic nanodrug delivery system by modifying nanoparticles with Gas6-overexpressing neural stem cell membranes for improving microglia targeting, pro-phagocytic properties and immunomodulatory effects, constructing a composite system designated as Gas6-NV-NPs. The system employs poly(lactic-co-glycolic acid) (PLGA) as a carrier to coencapsulate Rapamycin (RAP) and nicotinamide riboside (NR) (referred to as NPs), while leveraging Gas6 protein to specifically bind microglial surface receptors, enabling precise targeting of AD pathological regions. Our findings demonstrated that Gas6-NV-NPs restored lysosomal acidification in microglia, enhanced microglial phagocytic clearance of amyloid-\u03b2 (A\u03b2), and reinstated the anti-inflammatory phenotype in BV2 microglial cells. Furthermore, Gas6-NV-NPs exhibited favorable biosafety and robust brain-targeting capability in vivo, effectively promoting A\u03b2 clearance and neuronal repair in 5 \u00d7 FAD mice model of AD. This \"engineered membrane modification-nanodrug delivery\" synergistic strategy enhances therapeutic targeting and achieves multitargeted effects, offering a approach to overcoming critical bottlenecks in AD nanotherapy.\n\nID: 40744315\nTitle: Human neurons are susceptible to the internalization of small-sized nanoplastics.\nAbstract: Environmental pollution caused by small plastics has become a social concern due to growing awareness of their adverse impacts on organisms, including humans. While the brain has been identified as a major site of small plastic accumulation, fundamental information about their impacts at the cellular level remains limited. In this study, we investigated the neuronal uptake and toxicity of nanoplastics using the human neurons (LUHMES). LUHMES cells internalized polystyrene (PS) nanoplastics with a preference for 50\u202fnm particles, mainly through clathrin-mediated endocytosis and macropinocytosis. However, PS uptake by LUHMES cells was lower than that by other neural cell types. PS nanoparticles were predominantly localized in lysosomes and minimally in mitochondria. On the other hand, PS nanoparticles had no obvious effects on acute cytotoxicity, neurite outgrowth, and oxidative stress. This study provides essential data on the neuronal responses to nanoplastics and highlights the need for further evaluation of their neurodevelopmental impact.\n\nID: 40706951\nTitle: Toxicological profiling of polystyrene microplastics in raw 264.7 macrophages: Linking microplastic exposure to immune cell impairment.\nAbstract: The pervasive presence of microplastics (MPs), particularly polystyrene microplastics (PSMPs), has raised urgent concerns regarding their effects on human health. This study investigates the toxicological effects of spherical PSMPs (<0.50\u202f\u00b5m) on Raw 264.7 murine macrophages, critical immune cells that actively internalize foreign materials. At exposure concentrations ranging from 50 to 500\u202f\u00b5g/mL, PSMPs were rapidly internalized within 2\u202fh, with accumulation increasing over time. Notably, high-dose exposure (500\u202f\u00b5g/mL) resulted in significant mitochondrial membrane damage, lysosomal dysfunction, elevated reactive oxygen species (ROS) levels, and lipid peroxidation. These cellular stress responses were accompanied by increased levels of LDH and SOD, as well as the induction of apoptosis and cellular senescence. The findings show that PSMPs disrupt mitochondrial function and contribute to senescence responses, ultimately compromising immune cell viability and function. This study provides new insight into the intracellular fate and toxicity of environmentally relevant PSMPs and emphasizes the need for urgent evaluation of plastic pollution's impact on human health.\n\nID: 40665500\nTitle: Reversibility of Renal Fibrosis Induced by Exposure to Polystyrene Nanoplastics: The Dual Role of Lysosomes.\nAbstract: It has been demonstrated that nanoplastics (NPs) can accumulate in the kidney and induce nephrotoxicity. However, whether NPs induce renal fibrosis remains contentious, and the reversibility of NPs-triggered nephrotoxicity has rarely been reported. This study investigated the role of lysosomes in renal fibrosis induced by low-level polystyrene (PS) NPs with particle sizes of 100 and 500 nm (PS100 and PS500) in mice using Masson staining, immunohistochemistry, Western blotting, fluorescence imaging, and other techniques. The results showed that PS100 induced more pronounced renal fibrosis than PS500. Mechanistically, PS NPs promoted autophagosome formation accompanied by the inhibition of autophagic degradation. Moreover, PS NPs impaired lysosomal degradation function, evidenced by reduced CTSB and CTSD protein levels. This impairment blocked autophagic flux, thereby inducing renal fibrosis, which was further confirmed by in vitro results. Notably, lysosomal exocytosis plays a crucial role in the clearance of NPs from mouse kidneys through activating Mcoln1 expression, which contributes to restoring autophagic flux and alleviating renal fibrosis during recovery. Collectively, our findings provide the first evidence that lysosomes serve dual functions in the persistence and reversibility of NPs-induced nephrotoxicity, which could be valuable for the intervention and mitigation of kidney damage resulting from environmental NPs exposure.\n\nID: 40642859\nTitle: Mitochondrial Delivery of Molecular Drugs Bypassing Endocytosis.\nAbstract: Although mitochondria are potential therapeutic target for various diseases, the targeted delivery of drugs to mitochondria is challenging. Conventional carrier-based drug delivery utilizes an endocytic uptake pathway that results in partial and delayed mitochondrial targeting due to complicated endosomal trafficking followed by endosomal escape roots. Here, we report a nonendocytic approach for preferential and rapid mitochondrial delivery of molecular drugs using a designed nanocarrier. The drug-loaded nanocarrier rapidly enters into the cell via temporary membrane pore formation, releases molecular drugs into cytosol without any vesicular entrapment, and labels mitochondria within 5 min. In contrast, control nanocarrier-based delivery of the same molecule via endocytic root leads to lysosomal trafficking. This result demonstrates the advantage of the nonendocytic approach for efficient mitochondrial targeting of drugs with potential therapeutic advantages.\n\nID: 40607257\nTitle: Polystyrene Nanoplastics Exacerbate HFD-induced MASLD by Reducing Cathepsin Activity and Triggering Large Vacuole Formation via Impaired Lysosomal Acidification.\nAbstract: Environmental nanoplastics (NPs) have harmful effects on health. This study investigated the effects of polystyrene (PS) NPs on steatosis and fatty liver disease. PS-NP oral administration, in conjunction with a high-fat diet (HFD), synergistically exacerbated the symptoms of steatosis in mice, leading to increased alanine transaminase, aspartate aminotransferase, and cholesterol levels; no effects were observed with PS-NPs on a normal chow diet. Transcriptome analysis unveiled that PS-NPs interfered with actin organization, cell-cell adhesion, PPAR signaling, and lipid metabolism. In HepaRG cells, PS-NPs rapidly entered by inducing actin rearrangement, resulting in the formation of numerous small cytoplasmic vesicles. This treatment led to an augmented number of acidic organelles, leading to development and buildup of large vacuoles, indicative of enlarged pre-lysosomal and lysosomal compartments. PS-NP exposure hampered p62 degradation, leading to LC3B accumulation and decreased cathepsin B and D activity. Additionally, PS-NP exposure resulted in accumulation of lipid droplets and elevated expression of lipogenesis-, transport-, and storage-related genes. These findings suggest that excessive endocytosis driven by PS-NPs worsens MASLD in HFD through accumulation of lysosomes and large vacuoles with reduced cathepsin activity.\n\nID: 40598479\nTitle: Cancer cell membrane-camouflaged pH-responsive nanoparticles for enhancing siRNA effect and synergistic anti-tumor therapy.\nAbstract: RNA-based therapies, especially small interfering RNA (siRNA), have attracted extensive attention for tumor treatment. However, most siRNA can't exert a therapeutic effect due to a lack of targeting to tumor cells and entrapment in lysosomes upon administration. To address the challenges associated with siRNA delivery, a delivery system was developed using zinc oxide nanoparticles (ZnO NPs) coated with cancer cell membranes. ZnO nanoparticles (ZnO NPs) have been recognized as effective pH-responsive nanoparticles and are widely used in the development of pH-responsive drug delivery systems. The ZnO NPs were combined with chitosan to encapsulate siRNA, allowing for dissolution in acidic lysosomes and the subsequent release of siRNA and chitosan complexes. The dissolution of ZnO NPs would also disrupt lysosomes, facilitating the escape of siRNA and enhancing its gene silencing effect. However, the chitosan and ZnO NPs nano-complexes (CS/ZnO@siRNA) were unstable in solution and lacked a specific targeting effect for tumor cells. Thus, a homologous cancer cell membrane was coated onto the nanoparticles, which has been shown to be an effective strategy for enhancing their stability and targeting capabilities. Moreover, ZnO NPs not only dissolve in acidic lysosomes to enhance the efficacy of siRNA but also elevate oxidative stress levels in cells, leading to the induction of cellular apoptosis. It was demonstrated both in vitro and in vivo that the ZnO NPs could synergistically combine with the anti-tumor siRNA (siSurvivin) to inhibit the growth of the 4T1 tumor. Altogether, the developed drug delivery system (CCM-CS/ZnO@siSurvivin) offers a new strategy for enhancing the therapeutic effect of siRNA, while synergistically inhibiting tumor growth.

This study investigated the aggregation and deposition kinetics of six polystyrene NPs (PSNPs): NP50, NP100, NP500, A-NP50 and A-NP100 (amino-modified), and C-NP100 (carboxyl-modified), in artificial lysosomal fluid (ALF) and Gamble's solution (GMB). In ALF, PSNPs aggregated within 20\u202fmin to 132-1066\u202fnm, with rates ranking A-NP50\u202f>\u202fNP100\u202f>\u202fA-NP100\u202f>\u202fC-NP100\u202f>\u202fNP50\u202f>\u202fNP500. After 24\u202fh, most exceeded 5000\u202fnm, except NP500 (1473\u202fnm). In GMB, only positively charged A-NP50 aggregated substantially (> 5000\u202fnm), while negatively charged PSNPs remained stable. All PSNPs exhibited higher deposition rates in ALF than GMB. Higher particle concentrations promoted aggregation for all PSNPs in ALF, but only A-NP50 in GMB. Opposite pH effects on A-NP50 and NP50 were observed. Na2HPO4, NaHCO3, sodium pyruvate, and trisodium citrate promoted A-NP50 aggregation via electrostatic interactions and adsorption. BSA modulated aggregation in a concentration- and fluid-dependent manner: low levels (< 260\u202fmg/L) enhanced NP50 aggregation via charge screening, while higher levels stabilized it via steric hindrance. For A-NP50, BSA consistently reduced aggregation. These findings provide insights into NP transport and health risks in pulmonary environments.\n\nID: 40532836\nTitle: PPAR\u03b3 mediated lysosomal membrane permeabilization and lipophagy blockage were involved in microplastics and di (2-ethylhexyl) phthalate co-exposure induced immature testis injury.\nAbstract: Polystyrene microplastics (PS-MPs) and di (2-ethylhexyl) phthalate (DEHP), two main composites of plastic products, are always exposed to human at the same time. However, most existing research has focused on single exposure, which is not consistent with the actual exposure circumstance. In this study, single and co-exposure animal model were established. C57/BL6J mice were exposed to corn oil, 20\u00a0mg/kg PS-MPs, 200\u00a0mg/kg DEHP and PS-MPs\u00a0+\u00a0DEHP for 28 days. The HE staining showed more serious seminiferous epithelium disorganization in co-exposed mice, indicating that PS-MPs and DEHP co-exposure could aggravate testicular injury. Compared with control group, integrative analysis of transcriptomics and proteomics revealed that PPAR\u03b3 pathway played a crucial role in PS-MPs and DEHP co-exposure induced testis injury. In vitro, spermatocytes (GC-2) and leydig cells (TM3) were exposed to 50\u00a0\u03bcM MEHP, 10\u00a0mg/L PS-MPs and PS-MPs\u00a0+\u00a0MEHP for 48\u00a0h. Though PS-MPs and MEHP single exposure also triggered oxidative stress and PPAR pathway, the protein levels showed more remarkable difference in co-exposure group. Furthermore, co-exposure to PS-MPs and MEHP induced lysosomal membrane permeabilization (LMP), which significantly impaired lysosomal-mediated lipid degradation, thereby exacerbating lipid metabolism dysfunction in testicular cells. Treatment with N-Acetylcysteine (NAC) and knockdown of fatty acid-binding protein (FABP4) restored lipophagy flux and reduced lipid droplets deposition. Overall, co-exposure of PS-MPs and DEHP has synergistic toxic effect, inducing oxidative stress, PPAR\u03b3 activation and lipophagy blockage, finally resulting in unbalanced lipid metabolism and testicular damage.\n\nID: 40491850\nTitle: How Do Organelle-Targeting Nanotherapeutics Treat Inflammatory Diseases? A Comprehensive Review of the Literature.\nAbstract: Inflammation is a protective response of the body, but when excessive or prolonged, it can contribute to disease progression and tissue damage. Identifying more effective and less toxic drugs for treating both acute and chronic inflammatory diseases is a major challenge. Organelle-targeting strategies, which deliver drugs directly to specific organelles, offer a promising solution by improving treatment efficiency and minimizing toxic effects on healthy cells. However, despite the potential of organelles as therapeutic targets, precise targeting remains challenging. This review systematically summarizes organelle-targeting nanodelivery strategies for major organelles-mitochondria, the endoplasmic reticulum, lysosomes, and the Golgi apparatus-and the research progress in evaluating the potential of these strategies for treating inflammation-related diseases. This study focuses on the applications of these strategies for the treatment of sepsis, inflammatory bowel disease, atherosclerosis, and osteoarthritis. Additionally, this review outlines future directions and key challenges in this field, aiming to provide a scientific reference for the application of organelle-targeting nanotherapeutics for the treatment of inflammatory diseases.\n\nID: 40474178\nTitle: Polystyrene nanoplastics trigger pyroptosis in dopaminergic neurons through TSC2/TFEB-mediated disruption of autophagosome-lysosome fusion in Parkinson's disease.\nAbstract: Parkinson's disease (PD) is a sporadic neurodegenerative disorder with a rising incidence. Environmental toxins are considered the main etiological factor. The increasing use of polystyrene nanoparticles (PS-NPs) has raised concerns about their potential neurotoxic effects in PD. This study aimed to investigate the impact of PS-NPs on the onset and progression of PD and the underlying mechanisms. The breach of the blood-brain barrier (BBB) by PS-NPs was assessed using bioluminescence imaging, fluorescence observation, Pyrolysis-Gas Chromatography-Mass Spectrometry (Py-GCMs), transmission electron microscope (TEM), and Evans blue staining. To evaluate the potential promotion of PD by PS-NPs, a 30-day repeated oral administration study was conducted in vivo, during which behavioral changes and alterations in dopaminergic neurons in the substantia nigra were assessed. In vitro cytotoxicity assays were performed following PS-NPs intervention. Molecular biology techniques, including Western blotting and immunofluorescence, were employed to analyze proteins related to pyroptosis and autophagy-lysosomal pathway in both in vivo and in vitro settings. Additionally, proteomic sequencing was utilized to identify the upstream regulator of the autophagy-lysosomal pathway (ALP), and the effects of modulating this target protein on the ALP-pyroptosis pathway were analyzed. Bioluminescence imaging and Py-GCMs confirmed that PS-NPs entered the brain within 1.5\u00a0h. Evans blue staining and TEM showed PS-NPs damaged the BBB. The 30-day oral toxicity revealed that PS-NPs exacerbated behavioral abnormalities and caused dopaminergic neuron loss. Western blotting and immunofluorescence indicated that PS-NPs induced pyroptosis, disrupted autophagic flux, and lowered protein levels involved in autophagosome-lysosome fusion, both in vivo and in vitro. Furthermore, PS-NPs activated the mechanistic target of rapamycin (mTOR) and inhibited the nuclear translocation of Transcription Factor EB (TFEB). Proteomic sequencing identified a deficit of Tuberous Sclerosis Complex (TSC) 2 protein within the mTOR pathway. Immuno-coprecipitation and Coomassie Blue Fast Staining revealed that PS-NPs bound to TSC2 protein, causing disassembly of TSC1-TSC2 complex. These findings underscore how PS-NPs accelerated PD onset and progression by disrupting autophagosome-lysosome fusion through TSC2-mTOR-TFEB axis, which triggered protein degradation disorders and pyroptosis in dopaminergic neurons. The molecular mechanisms could inform environmental safety regulations concerning nanoplastics and inspire therapeutic strategies for PD.\n\nID: 40413758\nTitle: Defective autophagy in a fibroin secretion-deficient silkworm mutant.\nAbstract: The silkworm Bombyx mori is an economically important insect for silk production. Its silk glands are responsible for the synthesis and secretion of silk proteins. The naked pupa (Nd), a fibroin heavy chain mutant strain of silkworm, was found to exhibit severe atrophy, degeneration of the posterior silk gland (PSG), and abnormal secretion of fibroin proteins, thereby producing little or no silk. Here, we found that the autophagic marker Atg8-PE was upregulated through the target of rapamycin complex 1 signaling pathway in Nd. However, as autophagy substrates, SQSTM1/p62 and ubiquitinated protein levels increased in Nd. Furthermore, treatment with BafA1 showed no effect on the protein levels of SQSTM1/p62, indicating impaired autophagic flux in Nd. Abnormal acidification of lysosomes was further detected, which resulted in a decreased proportion of matured CtsL1 (cathepsin L1). Thus, the substrate in autolysosomes cannot be degraded within a rapid time frame, resulting in the accumulation of protein aggregates, which cause atrophy and degeneration of the PSG. We also found that acidic nanoparticles rescued lysosomal acidification and relieved the degenerative changes of Nd-PSG. The findings of this study suggest that the Nd mutant silkworm can be used as an animal model for studying protein aggregation diseases.Abbreviations: AD: Alzheimer disease; aNP: acidic nanoparticle; APP: amyloid beta precursor protein; Atg8: autophagy related 8; BACE1: beta-secretase 1; BafA1: bafilomycin A1; CtsL1: cathepsin L1; CRY: crystallin; ER: endoplasmic reticulum; FibH: fibroin heavy chain; FibL: fibroin light chain; FUS: FUS RNA binding protein; HD: Huntington disease; HRP: horseradish peroxidase; Nd: naked pupa; OSBPL2: oxysterol binding protein like 2; PD: Parkinson disease; PE: phosphatidylethanolamine; p-EIF4EBP: phosphorylated eukaryotic initiation factor 4E binding protein; PROM1: prominin 1; p-RPS6KB: phosphorylated ribosomal protein S6 kinase B; PSEN: presenilin; PSG: posterior silk gland; SDS-PAGE: sodium dodecyl sulfate-polyacrylamide gel electrophoresis; SEM: standard error of the mean; SOD1: superoxide dismutase 1; SQSTM1/p62: sequestosome 1; TARDBP: TAR DNA binding protein; TORC1: target of rapamycin complex 1; UBQLN2: ubiquilin 2; V-ATPase: vacuolar-type ATPase.\n\nID: 40380916\nTitle: Intracellular Nanodelivery of DNA with Enzyme-Degradable and pH-Responsive Peptide Dendrons.\nAbstract: Effective DNA delivery requires functional materials to package and transport genetic cargo into cells. However, many synthetic systems rely on heterogeneous mixtures, lack biodegradability, and pose toxicity concerns. Here, we introduce a peptide dendron single-molecule transfection reagent that enables targeted DNA delivery via pH-responsive, degradable nanoparticles with minimal toxicity. Peptide dendrons for intracellular delivery (PDIDs) incorporate ionizable non-natural amino acids for DNA binding and pH sensitivity. PDIDs formed stable nanoparticles that released DNA upon lysosomal acidification, facilitating cytoplasmic entry and subsequent gene expression. Rationally designed triamino acid blocks promoted protease degradation, reducing toxicity in preclinical models. Targeting ligands further enhanced the transfection efficiency by increasing cell uptake. In a lung metastasis model, targeted PDID-DNA nanoparticles selectively delivered therapeutic gene cargo to the lung, reducing tumor burden and extending survival. This platform demonstrates the potential to integrate natural and non-natural peptide features to enable safe and efficient DNA delivery in vivo.\n\nID: 40366876\nTitle: Light-triggered nanocarriers for nucleic acid delivery.\nAbstract: Gene therapy has evolved into a clinically viable strategy, with several approved products demonstrating its therapeutic potential for genetic disorders, cancer, and infectious diseases, and it has ample applications in regenerative medicine. Its success depends on the ability to efficiently and specifically deliver therapeutic nucleic acids (NAs) into target cells. Although viral or chemical carriers have been used in pioneering applications, safety concerns, and variable delivery efficiencies have prompted the search for alternative delivery vehicles. Light-mediated strategies have gained particular interest due to their biocompatibility and ability to improve the intracellular delivery efficiency. In this review, we focus on recent advancements in the development of light-triggered NA delivery carriers and discuss how they can be designed to overcome specific intracellular barriers. Additionally, we discuss notable therapeutic applications and highlight challenges and opportunities for translating this technology to a clinical setting.\n\nID: 40348093\nTitle: Charged dendrimers reduce glioblastoma viability by modulating lysosomal activity and HMGB1-RAGE interaction.\nAbstract: Dendrimers and dendrimer-based self-assembly systems have emerged as promising nanocarriers for a variety of applications, including anti-cancer therapies, modulation of the tumor microenvironment, and imaging. Here, we explored the therapeutic potential of two charged dendrimers, dendritic polyglycerol sulfate (dPGS) and dendritic polyglycerol amine (dPGA), in the context of glioblastoma multiforme (GBM). Docosahexaenoic acid (DHA) has shown potential in GBM. We therefore examined dPGS and dPGA effects alone and in combination with DHA. Using 2D cell models and 3D tumoroids, we showed that DHA with dPGA reduced tumor integrity and cell viability. dPGS reduced oxidative stress, whereas dPGA reduced lysosomal acidification, contributing to cellular dysfunction. Both dendrimers influence the interaction between high mobility group box 1 (HMGB1) and the receptor for advanced glycation end products (RAGE). The surfaces of the HMGB1-RAGE complex provide binding sites for interactions of charged molecules like dPGS and dPGA, suggesting the contribution of these interactions to cytotoxicity. In summary, our findings show that combining DHA with charged dendrimers (dPGS and dPGA) enhances GBM cytotoxicity through several mechanisms, involving lysosomal alkalinization, lipid peroxidation and modulation of the HMGB1-RAGE complex.\n\nID: 40203654\nTitle: PVC nanoplastics impair cardiac function via lysosomal and mitochondrial dysfunction.\nAbstract: MICRO: and nanoplastics (MNPs) are emerging environmental pollutants that pose a significant threat to human health, with traces found in cardiac tissues. While previous studies have indicated that MNPs can cantribute to cardiac dysfunction, there is limited systematic investigation into how MNPs exposure affects various organelles. This study focuses on polyvinyl chloride nanoparticles (PVC NPs), one of the most common and persistent plastic pollutants in the environment. Our findings reveal that PVC NPs engage in organelle-specific interactions, predominantly accumulating in the lysosomes and mitochondria of cardiomyocytes. This targeted accumulation results in substantial disruptions to lysosomal autophagic flux and mitochondrial energy metabolism. These results offer new insights into the organelle-specific mechanisms behind PVC NP-induced cardiotoxicity, highlighting the distinct risks associated with this widespread environmental contaminant.\n\nID: 40126054\nTitle: Enantiomer-Dependent Uptake of Chiral Nanoparticles in Macrophages Modulates the Inflammatory Response through the NF-\u03baB Pathway.\nAbstract: Infectious inflammation caused by pathogens or environmental pollutants remains a major global health issue. Therefore the development of novel strategies to efficaciously control infectious inflammation is urgently required. Nuclear factor-\u03baB (NF-\u03baB) as the central activator of pro-inflammatory genes plays a pivotal role in infectious inflammation. Here, nanoscale chirality was designed to modulate the inflammatory response through enantiomer-dependent blockade of the NF-\u03baB signaling pathway. Chiral gold nanoparticles (AuNPs) with good cytocompatibility were prepared through a one-pot seedless method under wild conditions, showing efficacious alleviation of lipopolysaccharide (LPS)-induced inflammation in vitro and in vivo only by AuNPs with levorotatory chirality (L-AuNPs) rather than the dextrorotatory enantiomer (D-AuNPs). Mechanism investigation elucidated that lysosomal acidification of macrophages was inhibited through a high cellular uptake of L-AuNPs due to their weak interaction energy with cell membranes. Accordingly, the NF-\u03baB rather than mitogen-activated protein kinase pathway was blocked by L-AuNPs through the selective inhibition of p65 phosphorylation, wherein the nuclear translocation of p65 was simultaneously depressed, so the secretion of pro-inflammatory mediators was reduced significantly. This study suggests that imparting chirality to nanoparticles can provide a novel protocol to efficaciously modulate health risks arising from infectious inflammation by improving the uptake of nanoparticles with anti-inflammatory activity.\n\nID: 42456394\nTitle: Defective lysosomal acidification promotes chondrocyte senescence and autophagic flux stagnation in geriatric osteoarthritis.\nAbstract: Geriatric osteoarthritis (G-OA) represents a senescence and metabolism-driven pathobiological phenotype, closely associated with ageing. Although lysosomal dysfunction is increasingly recognized as a cardinal feature of age-related diseases, most current therapeutic strategies primarily target upstream regulators of autophagy, particularly the PI3K/AKT/mTOR pathway. However, this approach may be limited in aged chondrocytes, where the efficiency of autophagic degradation is already compromised. With ageing, reduced vacuolar ATPase activity and the accumulation of intralysosomal lipofuscin may impair lysosomal acidification and degradative capacity. As a result, even when autophagy is pharmacologically stimulated, the clearance of autophagic cargo remains inefficient. This imbalance leads to the accumulation of undegraded autophagosomes, contributing to cellular stress and impaired autophagic flux. Importantly, lysosomal dysfunction under these conditions has increasingly been associated with the amplification of the senescence-associated secretory phenotype (SASP), activation of the NLRP3 inflammasome, and subsequent macrophage dysregulation. These interconnected processes may further exacerbate joint degeneration in G-OA. This review identifies lysosomal restoration as a potential therapeutic intervention point for overcoming downstream autophagic impairment in G-OA. Enhancing lysosomal acidification and degradative function may help re-establish effective autophagic flux and improve disease outcomes. Although several components of this proposed mechanistic framework require direct experimental validation in aged chondrocytes, the model provides a biologically plausible and testable basis for future investigations into lysosome-targeted therapeutic strategies for G-OA.\n\nID: 42441062\nTitle: Mannose-modified miR-223 nanoparticles remodel pathological microenvironment to suppress inflammation and angiogenesis for neovascular AMD therapy.\nAbstract: Age-related macular degeneration (AMD) is a leading cause of vision loss in the elderly, with neovascular AMD (nAMD) driven by choroidal neovascularization (CNV), persistent inflammation, and oxidative stress. Although combinatorial strategies targeting these pathological factors hold therapeutic promise, their clinical translation is constrained by the lack of effective delivery systems. In this study, we designed a mannose-functionalized poly(aspartic acid)-based nanocarrier bearing quaternary ammonium and boronic acid groups (MDA/QPABA) for the targeted delivery of microRNA-223 (miR-223). The system exploits charge-driven self-assembly to form stable nanoparticles with high loading efficiency, favorable colloidal stability, and tunable surface properties. The mannose moieties enable specific recognition by mannose receptors on target cells, facilitating cellular uptake and subsequent lysosomal escape. The resulting MDA/QPABA/miR-223 nanoparticles demonstrated pronounced anti-inflammatory, antioxidant, and anti-angiogenic activities in vitro. In a laser-induced CNV mouse model, they effectively reduced inflammatory and angiogenic cytokines, suppressed pathological neovascularization, restored retinal and choroidal structure, and preserved photoreceptor function, with an excellent biosafety. These findings highlight the potential of rationally engineered poly(aspartic acid)-based nanoarchitectures with tailored surface chemistry and biointerfacial properties for multifunctional nucleic acid delivery in nAMD therapy.\n\nID: 42440432\nTitle: Engineering oral celastrol-polysaccharide supramolecular nanoassemblies across intestinal barriers for the intervention of nonalcoholic steatohepatitis.\nAbstract: The development of effective oral therapies for nonalcoholic steatohepatitis (NASH) remains a critical unmet need in clinical practice. Celastrol (CEL), a potent natural compound, is a promising candidate for NASH due to its lipid-modulating, anti-inflammatory properties, and antioxidative properties. However, its clinical translation is severely hindered by poor oral bioavailability and a narrow therapeutic window stemming from significant toxicity. To overcome these limitations, we present the design and fabrication of novel, carrier-free CEL nanoparticles stabilized through natural polysaccharide self-assembly. This innovative formulation strategy is aimed at substantially enhancing the oral bioavailability of CEL, thereby augmenting its therapeutic efficacy in NASH while mitigating associated adverse effects. In this study, we developed a polysaccharide-CEL supramolecular depot comprising 42 distinct nanoassemblies for oral delivery in NASH, identifying chondroitin sulfate (CS) as the optimal polysaccharide adjuvant. The resulting CS/CNA formulation markedly improved oral absorption, with a 3.12-fold increase in observed systemic exposure based on AUC(0-t) compared with free CEL. Inhibitor-based mechanistic studies suggested that CS/CNA transport across intestinal epithelial cells may involve multiple endocytosis pathways and partial lysosomal escape. In a murine model of NASH, CS/CNA demonstrated potent therapeutic efficacy by modulating hepatic inflammation and reducing lipid accumulation. Critically, the nanoassembly exhibited a favorable safety profile, mitigating the toxicity associated with free CEL. By enhancing therapeutic efficacy while reducing adverse effects, this strategy effectively widens the therapeutic window for celastrol. This work establishes CS/CNA as a promising oral therapeutic candidate and provides a robust platform for advancing the clinical potential of CEL for NASH management.\n\nID: 42433394\nTitle: Polyamide and polyvinyl chloride microplastics induce cytotoxicity and cytokine release in primary normal human bronchial epithelial cells.\nAbstract: Our daily and continuous exposure to airborne micro- and nanoplastics (MNPs) together with the limited information on their potential hazards, warrants the need for more information on MNP-toxicity. In this study, we investigated the effects of diverse size ranges of amorphous MNPs from environmentally relevant polymers, on Air-Liquid-Interface (ALI)-cultured Normal Human Bronchial Epithelial cells (NHBEs) by analyzing immunological response parameters 24\u00a0h after exposure. In addition, we have used this setup to compare the responses of NHBEs to MNPs using nebulization or quasi-ALI (small droplet) exposure. NHBEs responded differently to exposures of polyamide (PA) or polyvinyl chloride (PVC) particles at nominal doses between 0.003 and 0.100\u00a0\u00b5g/cm2. PA particles\u2009<\u20091\u00a0\u03bcm (but not those\u2009>\u20091\u00a0\u03bcm) induced dose-dependent cell death, increased IL-8 secretion and decreased MCP-1 secretion. PVC particles (<\u20091\u00a0\u03bcm and 1-5\u00a0\u03bcm) induced cell death at lower concentrations than PA particles. Also, an increased IL-8 secretion and decreased MCP-1 secretion was observed for PVC particles in all size fractions (<\u20091\u00a0\u03bcm, 1-5\u00a0\u03bcm and 5-10\u00a0\u03bcm). Comparison of nebulization versus quasi-ALI exposure indicated differences related to the exposure method, but further experimental assessment is needed for definite conclusions and to ensure that the obtained data is relevant for toxicological effects occurring in humans. Our results indicate that PA and PVC particles increase IL-8 secretion and, PA only, decreases MCP-1 secretion. It needs to be established whether these effects on cytokines also indicate an activation of immune cells.

Anti-vascular endothelial growth factor agents, such as Bevacizumab (Beva), offer high specificity and low side effects. However, their limited ability to penetrate the corneal barrier necessitates invasive administration, significantly restricting their clinical application. Herein, we engineered (Beva&C\u2082G\u2082R\u2089)@Zn nanoparticles formed by co-assembling Beva, C\u2082G\u2082R\u2089 peptide and Zn2+, which decrease in size over time, as an efficient strategy for noninvasive Beva delivery across the corneal barrier to treat CNV. By combining various technologies (DLS, TEM, XPS, FTIR, and computer simulation), we discovered that the coordination between Beva and Zn2+ drives the nanoparticle formation, while the C\u2082G\u2082R\u2089 peptide facilitates its size evolution. Compared to size-stable nanoparticles of Beva@Zn and (Beva&R\u2089)@Zn, (Beva&C\u2082G\u2082R\u2089)@Zn nanoparticles exhibit rapid cellular internalization, efficient lysosomal escape, and effective corneal barrier penetration, leading to efficiently inhibit HUVEC cell migration and tube formation. Importantly, in a rat alkali-burned CNV model, (Beva&C\u2082G\u2082R\u2089)@Zn nanoparticles exhibited superior efficacy in inhibiting corneal neovascularization compared to size-stable nanoparticles, with the lowest inflammation index. The results of this study highlight the importance of controlling the size of nanoparticles to enable non-invasive delivery of macromolecular drugs across the corneal biological barrier, offering new insights for the design of future nanoparticle-based drug delivery systems.\n\nID: 42417458\nTitle: Evaluating the toxicity of polystyrene micro- and nanoplastics in human bronchial epithelial cells: differences and challenges using aerosol and suspension exposures.\nAbstract: Studies investigating toxicity of airborne micro- and nanoplastics (MNPs) are mostly based on conventional submerged cell cultures while limited studies utilize air-liquid interface (ALI) systems. Inherent differences in these culture/exposure modalities, such as particle behavior and deposited dose, likely affect cellular responses. To investigate this, we exposed submerged human bronchial epithelial cells (BEAS-2B) to polystyrene (PS) MNPs vs. aerosol exposure of ALI cultures. First, submerged bronchial epithelial cells (BEAS-2B) were exposed to suspensions of PS particles (50\u2009nm or 1\u2009\u00b5m) in four different applied concentrations (0.79-50\u2009\u00b5g/cm2; 24\u2009h). Second, BEAS-2B cells were cultured at ALI and exposed in a cloud system to PS 1\u2009\u00b5m particles (deposited dose: 55.4\u2009\u00b5g/cm2; 24\u2009h). Toxicity readouts focused on cytotoxicity (LDH release), inflammation (IL-8 release and transcriptional activation of inflammatory genes), and oxidative stress (DCFH-DA assay, antioxidant gene expression, and assessment of reduced/oxidized glutathione). In both models, PS exposure did not induce cell death, or an antioxidant response. However, NF-\u03baB transcriptional activity was strongly upregulated in submerged cells in response to both sizes of PS particles in a dose-dependent manner. Gene expression of CXCL1, CXCL2, and CXCL8 increased up to 7-fold after PS microplastic exposure (50\u2009\u00b5g/cm2) in the submerged model (which was less pronounced in response to PS nanoplastics) and 2-fold in the ALI model. In contrast, IL-8 secretion increased 1.6-fold for the ALI, but not the submerged model. Overall, both exposure modalities revealed an inflammatory response toward PS MNPs although with differences, likely due to significant differences in deposited dose. Very small plastic particles, called microplastics and nanoplastics (MNPs), are present in the air and can be inhaled into the lungs. To study possible health effects, scientists often expose lung cells to these particles in liquid (submerged) culture systems. However, this does not closely match how people are exposed through breathing. This study used a traditional liquid-based method and a more realistic system that exposes lung cells to plastic particles through the air. More specifically, human lung cells were exposed to polystyrene (PS) plastic particles of different sizes using either liquid exposure or an air\u2013liquid interface system, where particles were delivered as an aerosol, similar to inhalation. The researchers looked for signs of cell damage, inflammation, and oxidative stress. The results showed that the plastic particles did not kill the cells and did not cause oxidative stress in either exposure method. However, both methods caused signs of inflammation, which is a normal response of the body to foreign substances. In the liquid-based system, inflammation-related genes were strongly activated. In the air-exposed system, gene activation was weaker, but cells released higher levels of an inflammatory signaling protein. Importantly, the air-based exposure better reflects how people actually breathe in particles and avoids some problems linked to liquid-based testing. This study shows that there are differences in cellular responses to MNPs depending on the dose, particle behavior and culture system, which are all connected to each other.\n\nID: 42413915\nTitle: Unraveling Nanoplastics-Enzyme Interactions: Physicochemical, Structural, Functional, and Cell Biological Characterization of \u03b1-Amylase-Nanoplastics Complexes.\nAbstract: The topic of micro- and nanoplastics received significant attention in recent decades due to increasing environmental exposure, strong public perception, and emerging health concerns. While knowledge regarding detection and material characteristics has improved, the understanding of impact on cells remained unclear. As biological effects are initially caused by molecular interactions, consequently direct interactions with biomolecules, such as enzymes, are of particular relevance. In this occasion, effects may vary depending on the plastic type and particle properties. The specific aim of this study was to characterize the direct molecular interactions by means of selected model proteins and a variety of different nanoplastic particles. Therefore, the aim of the study was to exemplarily characterize \u03b1-amylase's (as a model enzyme) interactions with different nanoplastics and the resulting effects on enzyme structure and function, as well as cellular responses. The properties of the \u03b1-amylase-nanoplastic mixtures were analyzed using dynamic light scattering (DLS), Fourier-transform infrared spectroscopy (FTIR), fluorescence spectroscopy, and Phadebas amylase activity test. Additionally, Caco-2 cells were used as a model system for the human intestinal barrier and exposed to these complexes to evaluate cellular uptake through flow cytometry, microscopy, and viability testing. All applied nanoplastics interacted with \u03b1-amylase, forming complexes with adsorption affinities that depended on the particle type (PP \u226b PE > PET \u226b PLA). FTIR and fluorescence analyses showed particle-specific structural changes. Despite these differences in structural response, concentration-dependent enzyme inhibition was measurable, depending on the particle type. Uptake studies on Caco-2 cells indicated no internalization or cytotoxicity. These findings suggest that nanoplastics influence the enzyme structure and function based on their chemical properties, offering new insights into direct enzyme-nanoplastics interactions and their potential impacts on enzymes and cells.\n\nID: 42413336\nTitle: Morphology-associated ocular surface toxicity of micro- and nanoplastics: Fiber embedding contributes to persistent injury.\nAbstract: Micro- and nanoplastics (MNPs) are ubiquitous contaminants, yet how particle shape modulates ocular surface toxicity remains unclear. Here, we compared two red-fluorescent polystyrene spherical MNP preparations with nominal diameters of 80\u202fnm and 200\u202fnm, respectively, with red-fluorescent polyacrylonitrile Fiber MNPs (approximately 200\u202fnm in diameter and 2-3 \u03bcm in length) to define their effects on the corneal epithelium and ocular surface functional unit. In vitro, all MNP types were internalized by human corneal epithelial (HCE-T) cells with perinuclear accumulation and induced dose- and time-dependent cytotoxicity, including reduced viability, increased ROS, elevated TUNEL positivity, ZO-1 downregulation, and impaired epithelial migration; notably, 80\u202fnm PS MNPs elicited stronger early toxicity. In vivo, chronic topical exposure produced corneal epithelial damage, tear-film instability, conjunctival goblet-cell depletion, reduced corneal nerve density, and lacrimal gland inflammatory activation. Live imaging and scanning electron microscopy confirmed deposition, with Fiber MNPs showing surface embedding and disruption of corneal epithelial microvillar microarchitecture. Transcriptomic profiling with in vitro/in vivo validation showed enrichment of MAPK signaling and activation-associated changes in the MAP3K8-ERK/JNK/p38 axis, accompanied by a sustained pro-inflammatory transcriptional program, with more persistent inflammatory signaling in the Fiber MNP group. Together, these findings demonstrate particle type- and morphology-associated ocular surface toxicity of MNPs and support considering particle morphology together with polymer identity, size, and particle number in future ocular health risk assessment.\n\nID: 42398422\nTitle: Engineering miRNA-223 nanocomplexes via bioorthogonal self-assembly for precision therapy of intervertebral disc degeneration.\nAbstract: Intervertebral disc degeneration (IVDD) is characterized by inflammation-driven pyroptosis of nucleus pulposus (NP) cells. While oligonucleotide-based gene therapy holds promise for precision intervention, its clinical translation is hindered by inefficient cellular delivery and rapid lysosomal degradation. Here, we identified miRNA-223 as a pivotal regulator of IVDD, where its overexpression mitigated the inflammatory extracellular matrix (ECM) metabolic imbalance in NP cells in vitro. To overcome delivery barriers in vivo, we engineered an injectable multifunctional cell-penetrating peptide (CPP), R9-DOPA-DBCO, which spontaneously self-assembles with azido-modified miRNA-223 via bioorthogonal click chemistry to form nanocomplexes (R9-DOPA-miRNA223). These nanoparticles not only exhibited superior cell membrane penetration and lysosomal escape capabilities but also exhibited significant therapeutic efficacy in mitigating NP cell pyroptosis and restoring ECM metabolic homeostasis via the MKNK2/eIF4E/NOD-like signaling pathway, concomitantly attenuating IVDD progression in rat models. This direct and efficient delivery strategy not only has transformative potential for IVDD therapy but also broadens the conceptual and methodological framework for precision miRNA-based therapeutics.\n\nID: 42374161\nTitle: Dysregulation of the TFEB-ATP6V0C axis in microglia exacerbates \u03b1-synuclein pathology through impaired lysosomal acidification in Parkinson's disease.\nAbstract: Emerging evidence suggests that microglia exhibit dual regulatory roles in the pathogenesis of Parkinson's disease (PD); however, their precise function in \u03b1-synuclein clearance remains incompletely understood. Here, we provide compelling evidence that \u03b1-synuclein preformed fibrils (\u03b1-syn PFF) impair lysosomal acidification in microglia, leading to defective autophagic flux and disrupted \u03b1-syn degradation. This dysfunction further promotes the secretion of microglial extracellular vesicles (EVs), exacerbating disease pathology. Mechanistic investigations uncover that \u03b1-syn PFF directly interacts with ATP6V0C, a pivotal V0 subunit of V-ATPase. This interaction sterically hinders V0-V1 domain assembly, disrupting proton pump complex formation and reducing ATP6V0C expression. Functionally, ATP6V0C overexpression rescues lysosomal acidification deficits and facilitates \u03b1-syn degradation in vitro, while in vivo, ATP6V0C overexpression alleviates neurotoxicity and reduces phosphorylated \u03b1-syn aggregation in \u03b1-syn PFF mouse models. Further investigation identifies the PI3K-AKT-mTOR-TFEB pathway as a key regulatory axis of ATP6V0C-mediated lysosomal acidification in microglia. Notably, both TFEB activation and mTOR inhibition restore lysosomal acidity and upregulate ATP6V0C expression, thereby enhancing \u03b1-syn clearance. These findings establish the TFEB-ATP6V0C axis as a key determinant of microglial proteostasis, proposing targeted activation of this pathway as a promising strategy to mitigate PD progression.\n\nID: 42347404\nTitle: The Particle Size Effect: Cytotoxicity and Cellular Uptake of Polystyrene Nanoplastics in Human Keratinocytes.\nAbstract: Nanoplastics from plastic waste degradation pose a growing environmental health risk, yet size-dependent dermal effects remain poorly understood. This study investigated polystyrene nanoplastics of 50, 100, and 200 nm using ex vivo porcine skin and in vitro human keratinocyte models. Skin permeation, cellular uptake, viability, oxidative stress, inflammation, autophagy, and transcriptomic pathways were assessed. Enhanced nanoparticle penetration was observed in barrier-disrupted skin, primarily via hair follicles, with smaller particles showing greater intracellular accumulation. Transcriptomics revealed disruptions in oxidative stress, inflammation, endocytosis, and autophagy pathways. Specifically, 50 nm particles induced the strongest oxidative stress via Nrf2 activation and triggered sustained autophagy, leading to proliferation inhibition and time-dependent inflammation. In contrast, 100 nm particles caused moderate oxidative and inflammatory effects, whereas 200 nm particles provoked acute cytotoxicity, pronounced endocytosis, and an early inflammatory burst with subdued autophagy. These findings demonstrate that sub-100 nm PS NPs exhibit enhanced skin penetration in barrier-disrupted ex vivo models and induce pronounced oxidative stress, sustained autophagy, and proliferation inhibition in human keratinocytes. While these results suggest potential cellular mechanisms that may contribute to dermal toxicity, they do not directly demonstrate systemic absorption or long-term damage in vivo. Our observations provide a mechanistic basis for future in vivo investigations and highlight the need for caution when extrapolating in vitro findings to human health risks.\n\nID: 42339737\nTitle: Ex vivo pretreatment of donor organ with siRNA nanoparticles attenuates cold ischemia-reperfusion injury in cardiac transplantation.\nAbstract: Heart transplantation is an optimal therapeutic regimen for terminal-stage cardiac failure. However, cold ischemia-reperfusion injury (CIRI) remains an unavoidable and outstanding challenge, which is a significant obstacle to early graft dysfunction and long-term survival. Blockage of complement, apoptosis, and inflammation by small interfering RNA is considered a strategy for attenuating CIRI and protecting cardiac function. However, their delivery to the donor organ is still a serious challenge due to the polyanionic nature and high molecular weight properties. Here, we have designed a novel functionalized gene delivery system of direct delivery and sustained release of siRNAs targeting complement C3 (C3), Caspase-3, and nuclear factor \u03baB (NF-\u03baB) to treat the donor organ prior to transplantation. The functionalized gene delivery system (siRNA-TNPs), composed of CaCO3/CaP/TAT embellished carboxymethyl chitosan (CaCO3/CaP/TCMC) and synthesized through the co-precipitation method, efficiently encapsulates siRNAs during self-assembly. The siRNA-TNPs safeguards siRNAs from biological degradation, facilitates intracellular siRNA transfection, promotes lysosomal escape, and enhances the delivery efficiency of siRNA to the donor hearts. Perfusion of donor hearts with siRNA-TNPs prior to transplantation attenuated C3, Caspase-3, and NF-\u03baB genes expression of donor heart for at least 5\u00a0days after transplantation. Furthermore, silencing of C3, Caspase-3, and NF-\u03baB genes expression alleviated cell apoptosis, myocardial damage, tissue inflammation, and rejection and improved cardiac function. These data suggest that the multiple-target siRNA-TNPs solution can extend the preservation time for donor grafts, attenuate IRI, and protect cardiac function in murine models of heart transplantation, which provides a principal of concept for potential clinical translation.\n\nID: 42315500\nTitle: Supramolecular strategy for compartment pathogen clearance and immuno-metabolic homeostasis to treat periodontitis.\nAbstract: Periodontitis is an inflammatory disease driven by bacterial infection and immune dysfunction. Immune-subversive bacteria in the periodontitis microenvironment, such as Porphyromonas gingivalis, can evade conventional therapies by invading cells and inducing lysosomal dysfunction. Here we develop an injectable supramolecular hydrogel through the co-assembly of recombinant human type I collagen (COL), poly-\u03b5-lysine (PL), and puerarin (PUE). Supramolecular amorphization improves PUE's solubility and permeability, enabling a dual-compartment antibacterial strategy via effective trans-barrier delivery. Extracellularly, PL and PUE synergistically disrupt bacterial membranes and metabolism, while concurrently mitigating bacterial toxin induced pro-inflammatory macrophage polarization. Intracellularly, the supramolecular complexes facilitate PUE accumulation in phagolysosomes. By counteracting local oxidative stress, the internalized PUE restores lysosomal acidification and alleviates bacteria-induced immuno-metabolic dysregulation. In vivo, the hydrogel manipulates the local inflammatory microenvironment and facilitates periodontal tissue repair. This study provides a clinically translatable supramolecular strategy for treating intracellular infections and restoring tissue homeostasis.\n\nID: 42307976\nTitle: Personalized Pathogenic Nanoplastic Coronas Orchestrate Efferocytosis-Driven Immune Evasion in Lung Adenocarcinoma.\nAbstract: Airborne nanoplastic (NP) pollution is an emerging threat to respiratory health. Although inhaled NPs rapidly acquire a protein corona that shapes their bioactivity, the consequences of this process in cancer-susceptible lungs remain unclear. Here, we investigated whether NPs form a disease-specific pathogenic protein corona in lung adenocarcinoma that rewires immune signaling and accelerates tumor progression. Polyethylene terephthalate (PET) NPs were generated by mechanical fragmentation and extensively characterized. In tumor-bearing mice, inhaled PET NPs accelerated tumor growth relative to controls. Proteomic analysis of PET NPs incubated with bronchoalveolar lavage fluid from patients with lung adenocarcinoma identified lysozyme (LYZ) as a selectively enriched corona component associated with tumor stage and metastasis. Corona formation induced conformational remodeling of LYZ, enhanced its enzymatic activity, and prolonged its membrane retention. Mechanistically, corona-bound LYZ engaged Toll-like receptor 4 and activated a PGRN-LXR\u03b1 signaling axis, thereby increasing lysosomal acidification-dependent efferocytosis, promoting M2 macrophage polarization, and reducing CD8+ T-cell infiltration. In vivo, AAV9-mediated knockdown of LYZ or PGRN attenuated PET NP-induced efferocytosis, reversed immunosuppressive reprogramming, restored CD8+ T-cell infiltration, and suppressed tumor growth, demonstrating the functional requirement for this corona pathway. These findings establish disease-derived PET NP coronas as active nano-bio interfaces that connect environmental PET NP exposure with efferocytosis-driven immune evasion in lung adenocarcinoma. This work provides a mechanistic link between airborne NPs and tumor progression in susceptible hosts and highlights corona-mediated signaling as a potential therapeutic target and environmental health concern.\n\nID: 42305091\nTitle: Vacuolar H+-ATPase Preserves Cardiolipin Homeostasis Through the Lysosomal-Mitochondrial Axis to Restrain Cardiac Aging.\nAbstract: Cardiac aging involves progressive mitochondrial dysfunction, contributing to heart failure. Cardiolipin (CL), essential for mitochondrial function, is increasingly depleted in aging cardiomyocytes, promoting mitochondrial decline. Lysosomal degradation relies on v-ATPase (vacuolar-type H+-ATPase)-mediated acidification, and although lysosomes regulate phospholipid metabolism, their roles in CL homeostasis during aging remains unclear. This study examines whether v-ATPase dysfunction drives age-related cardiac changes by disrupting CL metabolism and mitochondrial function. To investigate underlying mechanisms and causality, we use RNA sequencing, targeted lipidomics, immunofluorescence microscopy, (co)immunoprecipitation, proximity ligation assays, subcellular fractionation, mitochondrial respiration analysis and echocardiography, a cardiolipin synthase-1 (Crsl1) knockout mouse model, and 2 v-ATPase knockout models. In addition, we assess whether a nutraceutical intervention targeting v-ATPase dysfunction can mitigate heart failure in aging mouse models and elderly people. Our present findings reveal a sequence of events driving age-related cardiomyopathy: declining cardiac nicotinamide adenine dinucleotide levels impair v-ATPase-mediated lysosomal acidification by weakening the interaction between nicotinamide adenine dinucleotide-dependent glycolytic enzyme aldolase and v-ATPase. This disruption increases lysosomal membrane permeability by reducing lysosomal acidification, allowing cathepsin B to leak into mitochondria. There, cathepsin B disrupts mitochondrial CRLS1 (cardiolipin synthase I), impairing CL synthesis and remodeling. The resulting CL deficiency causes mitochondrial oxidative stress and programmed cell death, leading to mitochondrial and cardiac dysfunction. Genetic or chemical inhibition of v-ATPase and of CRLS1 in mouse models reproduce these age-related defects, highlighting their central roles in cardiac aging. Restoring nicotinamide adenine dinucleotide levels rescues lysosomal acidification and CL metabolism, protecting against age-related cardiomyopathy in rodents and humans. Augmenting v-ATPase-mediated lysosomal acidification offers novel therapeutic strategies to combat age-related cardiomyopathy by rewiring CL homeostasis.\n\nID: 42302456\nTitle: Polystyrene nanoplastics elicit early mitochondria-associated phenotypic, metabolic, and functional responses in human hepatocytes.\nAbstract: Nanoplastics have recently been detected in human liver tissue, raising concerns about their potential impact on liver function. However, early hepatocyte responses associated with nanoplastics exposure remain poorly understood. Here, we combined high-throughput Cell Painting-based phenomics, untargeted metabolomics, and Seahorse mitochondrial functional assay to investigate the effects of 100\u00a0nm polystyrene nanoplastics on human HepaRG hepatocytes, a surrogate for primary human hepatocytes. At the tested concentrations (6.25-100\u00a0\u00b5g/mL), exposure did not induce overt cytotoxicity, enabling assessment of early sublethal cellular responses. Phenomics revealed widespread subcellular perturbations, with 16.4% of the measured phenotypic features significantly altered. Mitochondria-associated features represented the dominant altered phenotypic signature, showing pronounced changes in granularity, texture, and radial distribution, alongside alterations in endoplasmic reticulum- and cytoskeleton-associated features. Untargeted metabolomics of intracellular metabolites and the extracellular secretome revealed metabolic alterations, characterized by changes consistent with altered \u03b2-oxidation, lipid handling, membrane stress, and central carbon metabolism, including changes in the tricarboxylic acid (TCA) cycle and amino acid catabolism. Pathway analysis identified the TCA cycle as one of the most significantly affected pathways (FDR\u00a0=\u00a00.028). Integrated phenomic-metabolomic analysis revealed strong correlations between mitochondrial phenotypic features and metabolites involved in lipid and energy metabolism, indicating a coordinated structural-metabolic response to polystyrene nanoplastics exposure. Functional assessment using Seahorse assay showed reduced basal and maximal respiration and decreased ATP-linked O2 consumption. Together, these findings provide evidence that 100\u00a0nm polystyrene nanoplastics elicit early mitochondria-associated phenotypic, metabolic, and functional responses prior to overt cytotoxicity under the tested conditions. They also highlight the value of phenomic-metabolomic-functional integration for profiling sublethal nanotoxicological responses and guiding future targeted mechanistic studies.\n\nID: 42290028\nTitle: Investigating the Impact of Carboxylated Polystyrene Nanoplastics in the Liver Using Cell Lines and Precision-Cut Liver Slices.\nAbstract: Increasing reports of plastic accumulation in human tissue have raised concerns about potential adverse health outcomes. Evidence of negative effects of nanoplastics is heterogeneous and provides limited insights into the underlying pathogenic toxicity mechanisms in humans. In the present study, carboxylate-modified fluorescently labelled polystyrene nanoparticles (PS NPs) were used to investigate uptake and cytotoxicity in three different hepatic models of varying complexity, including HepG2 cells, IHH cells, and human precision-cut liver slices (hPCLS). The results show model- and dose-dependent effects on hepatocytes. 74.2%\u2009\u00b1\u200913.4% of the IHH cells showed PS NPs uptake at 0.1\u2009\u03bcg/mL, which is considerably lower than the estimated plastic concentration in human blood (1.8-4.7\u2009\u03bcg/mL). The viability of IHH cells decreased to 10.6%\u2009\u00b1\u20099.1% after exposure to 100\u2009\u03bcg/mL for 48\u2009h. Early signs of hepatic injury were found in hPCLS at high concentrations. No changes were observed in the redox state and mitochondrial respiratory parameters of HepG2 cells after exposure. The PS NPs exposure experiments show uptake across all three hepatic models and toxic effects in IHH cells and hPCLS. Overall, the study highlights the need for physiologically relevant human tissue models to understand the impact of nanoplastic pollution on human health. Particles of plastic described as microplastics (MP) and nanoplastics (NP) are accumulating in the environment from a range of sources, including the fragmentation of large plastic items during use and after disposal. NPs are invisible to the naked eye and can enter the human body by consuming food and drinks and breathing air containing these particles. Once inside the body, NPs can reach and accumulate in the organs and body tissues. This study used three models of the liver to test what happens after exposure to polystyrene NPs. It shows that polystyrene NPs can accumulate in the liver cells even at low exposure levels and can also cause damage and death of liver cells at higher levels. The study adds to the scientific evidence of harmful effects of NPs on human health, the environment, and economies and pushes for policies towards a sustainable future.\n\nID: 42287918\nTitle: Food allergen binding to pristine PET nanoplastic and their effect on allergic immune responses in vitro.\nAbstract: Plastic pollution is steadily increasing and has been linked to several diseases. At the same time, there has been an increase in allergic diseases over the past decades, with evidence suggesting a connection to environmental pollution. Since human exposure to plastic pollution is inevitable, the effects of nanoplastics (NPs) on allergic responses need to be elucidated. Therefore, we investigated the binding of food allergens to various pristine polyethylene terephthalate (PET) NPs, and their effect on allergic responses in vitro. We found that nanosized PET (nPET) NPs did not induce acute or long-term cytotoxicity in peripheral blood mononuclear cells and Caco-2 cells, nor did they cause epithelial barrier disruption using 5\u202f\u00b5g\u202fmL-1. Furthermore, allergen transport over Caco-2 monolayers was not affected by long-term exposure to nPET. Importantly, food allergens (bovine \u03b2-lactoglobulin, shrimp tropomyosin and bovine lactoferrin) were bound with different affinity to PET NPs (Kd 4.6-107.1\u202fnM). This was reflected in the ability of the allergens to influence aggregation behavior, as well as in the varying amounts of allergen bound in the hard corona. When presented to monocyte derived dendritic cells, allergens in the nPET corona were taken up to a higher extent than allergens alone. However, no changes in activation of co-stimulatory markers were found. Finally, the allergenic activity of allergens in the nPET corona was preserved compared to allergen alone, assessed by a mediator release assay and basophil activation test. In conclusion, we found that PET NPs can carry allergens that are internalized to a higher extent by monocyte-derived dendritic cells than non-bound allergens and can activate effector cells ex vivo, which may affect the immune response in allergic individuals.\n\nID: 42274675\nTitle: Developing a New Approach Methodology Framework to Assess Biological Responses to Nanoplastics: Insights from Polystyrene and Biodegradable Particles.\nAbstract: The widespread presence of micro- and nanoplastics (MNPs) in the environment represents an emerging risk for human and environment health. New Approach Methodologies (NAMs) offer valuable tools to improve the mechanistic understanding of nanoscale processes and support hazard identification without animal testing. This study investigated the biological effects of exposure to 0-100 \u00b5g/mL 100 and 20 nm polystyrene (PS-NPs) and 100 nm polycaprolactone nanoplastics (PCL-NPs) using advanced in vitro intestinal models and the 3R-compliant in vivo Caenorhabditis elegans model. In vitro endpoints included cytotoxicity, oxidative stress, DNA damage, cellular internalization, and barrier integrity, while in vivo analyses focused on oxidative stress and locomotor behavior across multiple exposed generations. PS-NPs induced significant DNA damage in vitro, particularly at \u226550 \u00b5g/mL after 24-48 h exposure, and were rapidly internalized by cells, with 20 nm particles also detected in the nucleus. In contrast, 100 nm PCL-NPs elicited weaker biological responses. In vivo, PS-NPs caused an increase in oxidative stress response and locomotor behavior across exposed generations, whereas PCL-NPs produced milder effects, consistent with in vitro findings. These results support the potential of integrated NAMs for assessing human health risks associated with MNP exposure within a One Health framework.\n\nID: 42265723\nTitle: Surface-driven endocrine activity of nanoplastics: polymer- and size-dependent estrogen and androgen receptors modulation without steroidogenesis perturbation.\nAbstract: Growing production and use of plastics have led to significant environmental pollution including the formation and accumulation of plastic nanoparticles (PNPs). Due to their small size, PNPs easily enter the human food chain; however, humans are also exposed to plastics through other consumer pathways, such as the use of cosmetic products. Despite considerable efforts to investigate the potential adverse effects of plastics, their impact on human health is not yet fully understood. In particular, endocrine disruption has emerged as a potential mechanism underlying reported reproductive and hormonal effects of micro- and nanoplastics. We applied an OECD-aligned in vitro test guidelines (TGs) to a factorial panel of eight PNPs spanning four common polymers (polystyrene (PS), polyethylene (PE), polypropylene (PP), polyethylene terephthalate (PET)) with size-resolved materials and polymer-matched mixtures. Thus, estrogen receptor a (ER\u03b1) transactivation (TG 455), androgen receptor (AR) transactivation (TG 458, antagonist mode), and H295R steroidogenesis (TG 456) assays were performed using HeLa-9903, AR-EcoScreen GR KO M1, and NCI-H295R cell models, respectively. Across 0.1-10\u00a0mg L\u207b\u00b9, no cytotoxicity was observed. PENPs (350\u00a0nm) and PPNPs (180\u00a0nm) acted as ER agonists, whereas PPNPs (50 and 180\u00a0nm) and PENPs (350\u00a0nm) antagonized AR; PSNPs and PETNPs showed no activity when tested individually. Notably, several mixtures elicited ER and AR responses even when constituent singles were inactive, indicating mixture-dependent potentiation. In contrast, the H295R assay did not meet the OECD decision rule for altered steroidogenesis: sporadic shifts in pathway intermediates did not propagate to estradiol or testosterone. Altogether, the data support a surface- and polymer-dependent, receptor-proximal mode of action for PNPs and highlight mixture effects as a critical, underappreciated driver. These results move endocrine hazard evaluation beyond polystyrene surrogates and provide decision-useful guidance on which polymers/sizes and mixture contexts merit priority in exposure monitoring and risk assessment.\n\nID: 42264605\nTitle: Micro- and nanoplastics as vectors of aquatic pollutants and genotoxicity: An integrated review across aquatic and mammalian systems with special reference to the scenario in India.\nAbstract: Microplastics (MPs) and nanoplastics (NPs) are environmental pollutants with paramount implications for aquatic ecosystems and, through that route, human health, particularly due to their oxidative stress-mediated genotoxic potential. This review is a synthesis of findings from recent studies, with emphasis on the scenario in India, on the bioavailability, toxicological risks, and cellular mechanisms of MPs and NPs (MNPs) in various organisms, separately addressing evidence from aquatic models, including marine mussels, common carp, zebrafish, rotifers, etc., and mammalian systems relying essentially on in vitro studies. Key evidence indicates that MPs adsorb persistent organic pollutants like Polycyclic Aromatic Hydrocarbons (PAHs), enhancing their bioavailability and inducing oxidative stress, immunological alterations, and developmental toxicity, which are closely associated with DNA damage and chromosome instability. As regards aquatic organisms, combined exposure to MPs and heavy metals to fish models exacerbates biochemical disruptions and immune suppression, along with oxidative stress-linked genotoxic responses such as DNA strand breaks and micronucleus formation. Zebrafish embryos exhibit microcirculation dysfunction and pathological angiogenesis upon NP exposure. Mammalian cell studies reveal size-dependent cytotoxicity, with smaller NPs causing greater oxidative damage and membrane disruption, which triggers mitochondrial dysfunction, excessive ROS production, cell-cycle arrest, and activation of DNA damage response pathways, evidenced by micronucleus formation, chromosomal abnormalities, and oxidative DNA lesions. Overall, toxicity is influenced by particle size, charge and co-contaminants, with oxidative stress emerging as the central mechanism that connects cellular toxicity to genetic damage. This review underscores the urgent need for integrated, multidisciplinary approaches to assess the environmental and toxicological risks of MNPs with special emphasis on standardized genotoxicity assessment, while informing regulatory and mitigation strategies for the future.\n\nID: 42253471\nTitle: Polyethylene terephthalate and polypropylene nanoplastics toxicity in vitro: Comparative analysis of paraquat adsorption and cytotoxicity.\nAbstract: According to global statistics, approximately 400\u00a0million tons of plastic are produced worldwide each year, yet only about 9% is recycled. Environmental degradation of plastics generates microplastics and nanoplastics, which have been shown to induce oxidative stress, genotoxicity, and endocrine disruption. Additionally, nanoplastics can adsorb environmental pollutants, act as transport vectors within biological systems, and alter pollutant toxicokinetics. In this study, we conducted a comparative analysis of paraquat adsorption and in vitro cytotoxicity of polyethylene terephthalate nanoplastics (n-PET) and polypropylene nanoplastics (n-PP). The results showed that n-PET exhibited significantly higher adsorption capacity for paraquat than n-PP, with maximum interaction observed at pH 11 and particle sizes below 100\u00a0nm. In vitro experiments using the human embryonic kidney (HEK-293) cell line demonstrated higher cytotoxicity for n-PET compared to n-PP. Co-exposure to n-PET and paraquat resulted in significantly greater cytotoxic effects than exposure to either agent alone. IC\u2085\u2080 values were determined at 24, 48, and 72\u00a0h. Furthermore, both nanoplastics disrupted cellular redox homeostasis, with n-PET inducing a more pronounced oxidative imbalance than n-PP. These findings indicate that n-PET may act as a stronger carrier of paraquat and pose a greater toxicological risk under co-exposure scenarios, highlighting the importance of nanoplastic-pollutant interactions in environmental risk assessment.\n\nID: 42251935\nTitle: Innovative mucosal nanocarrier systems for enhanced immune response against respiratory pathogens.\nAbstract: Effective pulmonary vaccination remains limited by the pulmonary surfactant (PS) barrier and inefficient intracellular delivery of vaccine cargo to alveolar antigen-presenting cells, particularly alveolar macrophages. Inspired by the natural compatibility of alveolar macrophage-derived vesicles with the alveolar environment, we developed biomimetic alveolar macrophage membrane vesicles (AMVs) as a mucosal nanocarrier platform. This study aimed to develop a nanovaccine platform that addresses key extracellular and intracellular barriers in the lung and to evaluate its immunogenicity and protective efficacy in multiple respiratory pathogen models. AMVs were engineered to improve performance in the PS environment and to achieve preferential uptake by alveolar macrophages. An Antigen Capture and Cytosolic Delivery System (ACCDS) was incorporated, comprising: (1) an engineered surfactant protein A domain for broad pathogen binding; (2) a pH-responsive listeriolysin O module designed to facilitate endo/lysosomal escape and enhance cytosolic access of cargo; and (3) encapsulated Poly(I:C) to activate TLR3 and support RIG-I/MDA5-associated signaling. AMV-ACCDS-Poly(I:C) showed improved delivery performance in the PS-associated environment and preferential uptake by alveolar macrophages compared with synthetic nanoparticles and a commercial transfection reagent. Dual innate activation was associated with stronger IFN-\u03b2 and IL-18 responses than those induced by the tested control formulations. The platform promoted the local establishment and/or differentiation of lung-resident memory-like CD8+ T cells and was accompanied by IL-18-associated metabolic remodeling. In prime-boost studies, it conferred complete protection in lethal influenza and pseudorabies virus challenge models and reduced pulmonary burden in a Mycoplasma infection model. AMV-ACCDS-Poly(I:C) provides a biomimetic strategy to address key barriers in pulmonary vaccination and supports the potential of membrane-based mucosal vaccine systems for protection against respiratory pathogens.\n\nID: 42242613\nTitle: Biocompatibility of Orthodontic Aligner Materials in the Digital Workflow: A Quantitative In Vitro Comparison of Thermoformed, Directly Printed, and Polyamide-12 Systems.\nAbstract: Directly 3D-printed aligners (DPAs) have recently emerged as a promising development in orthodontics, offering greater design flexibility and in-office manufacturing. However, their biological safety remains incompletely characterised, particularly regarding the release of micro- and nanoplastics (MNPs) during clinical use. This study evaluated the in vitro cytocompatibility of eight orthodontic aligner materials, including thermoformed systems, directly 3D-printed resins, and a polyamide-12 (PA-12) device, using MTT cell-viability assays on human dental pulp stem cells (hDPSCs). Standardised specimens were prepared according to manufacturer-recommended protocols, while MNP suspensions were generated by controlled abrasion and sonication. Cells were exposed to material eluates at concentrations of 500, 1000, and 5000 ng/100 \u00b5L for 24 to 96 hours. Cell viability and morphological analyses revealed marked material-, dose-, and time-dependent differences. Thermoformed materials and the polyamide-12 system generally exhibited more stable profiles, with viability frequently above 70% and preserved cell morphology. A subset of materials showed non-linear responses suggestive of a hormetic-like effect. By contrast, several directly 3D-printed resins showed greater reductions in viability, approaching moderate cytotoxicity at higher concentrations and longer exposure. Within the limitations of this in vitro study, thermoformed materials and polyamide-12 showed more consistent cytocompatibility than some directly printed materials. These findings highlight the need for systematic biocompatibility evaluation of orthodontic aligner materials and indicate that adherence to standardised post-curing protocols and rigorous material qualification workflows is essential to minimise potential biological risks during clear aligner therapy.\n\nID: 42229818\nTitle: Cigarette smoke-induced ClC-3 deficiency drives chronic bronchitis via the AKT/CREB1 axis and lysosomal-autophagic impairment.\nAbstract: Cigarette smoke (CS) exposure disrupts bronchial epithelial redox homeostasis, serving as a primary etiology of chronic bronchitis; however, the specific mechanisms linking ion transport dysregulation to CS-induced cytotoxicity remain poorly understood. This study identifies a critical protective role for the voltage-gated chloride channel ClC-3, a Cl-/H+ exchanger, in maintaining airway epithelial integrity against oxidative insult. We report significant downregulation of ClC-3 in the bronchial epithelium of chronic bronchitis patients and CS-exposed mice. Using transgenic overexpression and conditional knockout mouse models, we demonstrate that ClC-3 deficiency exacerbates, while its overexpression mitigates, CS-induced airway inflammation, systemic oxidative stress (SOD/MDA), and lung injury. Mechanistically, we show that CS exposure suppresses AKT phosphorylation, leading to the inactivation of the transcription factor CREB1. We validate that CREB1 acts as a direct transcriptional activator of CLCN3 by binding to its promoter; thus, the CS-mediated inhibition of the AKT/CREB1 axis results in transcriptional silencing of ClC-3. At the cellular level, loss of ClC-3 disrupts lysosomal acidification, resulting in a blockade of autophagic flux. This impairment prevents the effective clearance of oxidative damage, thereby promoting epithelial cell death and amplifying inflammatory responses. Collectively, these findings delineate a novel \"CS-AKT/CREB1-ClC-3-Lysosome\" axis, suggesting that restoring ClC-3-mediated lysosomal function represents a promising therapeutic strategy to restore redox balance in chronic bronchitis.\n\nID: 42226817\nTitle: Distinct pro-inflammatory responses to pristine and microbially contaminated PET nanoplastics in a human alveolar cell co-culture.\nAbstract: The small size of nanoplastics (NPs; <1\u00a0\u00b5m in diameter) facilitates airborne transport, inhalation, and deposition in the lungs, raising significant concerns about potential effects on human health. In occupational settings, such as waste management and recycling facilities, exposure to NPs carrying microbial contaminants may pose an additional health risk to workers. In the present study, we investigated pulmonary cytotoxicity and pro-inflammatory responses after exposure to polyethylene terephthalate nanoplastics (PET-NPs) with or without microbial contaminants. PET-NPs were synthesized from a post-consumer juice bottle (PET b001) and commodity PET pellets (PET c000). The presence of microbial contaminants was assessed via receptor activation in HEK293 Toll-like receptor (TLR) reporter cells expressing TLR2 or TLR4. Co-cultures of human alveolar epithelial cells (A549) and monocyte-derived macrophages (dTHP-1) were exposed to PET-NPs (0, 10 or 100\u00a0\u03bcg/mL) that tested either negative or positive for TLR2 and TLR4 activation. After 24\u00a0h, cell viability was measured, and cytokine responses were quantified at both mRNA and protein levels. PET b001 activated TLR2 and TLR4, indicating the presence of biologically active microbial components, whereas PET c000 showed no activation. In A549/dTHP-1 co-cultures, PET b001 (10 and 100\u00a0\u03bcg/mL) significantly increased IL-1B, IL-6, IL-8, and TNF mRNA levels and IL-6 and IL-8 protein secretion. In comparison, PET c000 selectively increased IL-8 mRNA levels and protein secretion, and only at the highest tested concentration (100\u00a0\u03bcg/mL). No changes in cell viability were observed for either particle type. We found that the pro-inflammatory responses to PET-NPs are largely mediated by associated microbial components rather than the polymer itself, highlighting the importance of accounting for environmental context when evaluating their health risks. No evidence of cytotoxicity was observed, as cell viability remained unchanged. Our results further emphasize the need to assess microbial contamination prior to toxicity testing and point to potential occupational health risks in plastic waste and recycling environments.\n\nID: 42225596\nTitle: Umbrella Review on Micro and Nanoplastics: Mapping the Scientific Landscape.\nAbstract: Micro- and nanoplastics (MNPs) are emerging contaminants widely distributed across environmental compartments and associated with potential ecological and human health risks. Given the rapid expansion of review literature on this topic, we conducted an umbrella review integrating scientometric mapping and thematic synthesis to evaluate research trends, methodological patterns, convergent evidence, and knowledge gaps in MNPs research. Review articles indexed in the Web of Science Core Collection up to June 2025 were analyzed using combined manual refinement, automated text-mining workflows, and CiteSpace network analyses. A total of 7,349 review articles were included. The results revealed strong thematic concentration around aquatic ecosystems, fish-based models, contamination studies, and adverse biological effects, particularly involving polyethylene (PE), polystyrene (PS), polypropylene (PP), and polyethylene terephthalate (PET). There was a broad consensus on the widespread environmental occurrence of MNPs and their potential to induce oxidative stress, inflammation, cytotoxicity, and bioaccumulation. However, substantial methodological heterogeneity and structural biases were identified, including the predominance of narrative reviews, limited taxonomic diversity, and inconsistent analytical and experimental approaches. Several domains remained comparatively underexplored, especially environmental transport, degradation pathways, microorganism interactions, combined exposure scenarios, and environmentally realistic conditions. In addition, terrestrial organisms, atmospheric systems, and less frequently studied polymer types remain insufficiently represented in the current review literature. Overall, this umbrella review demonstrates that, despite the rapid consolidation of MNPs research, important limitations persist regarding evidence integration, methodological standardization, and ecological representativeness. These findings highlight the need for more integrative, standardized, and ecologically relevant approaches capable of improving ecological risk assessment and advancing the understanding of MNPs dynamics and impacts across environmental systems.\n\nID: 42223068\nTitle: Biomimetic Nanoparticles Based on Tumor Cell Membrane Co-loaded with Vitamin E and Doxorubicin for Targeted Synergistic Treatment of Bladder Cancer.\nAbstract: The development of targeted nanotherapeutics that enhance tumor specificity while minimizing systemic toxicity remains a central challenge in bladder cancer treatment. Herein, we engineered a biomimetic nanoplatform (mPPE@DOX) by cloaking a poly(ethylene glycol)-block-poly(\u03b5-caprolactone) (PEG-b-PCL) core, co-loaded with doxorubicin (DOX) and vitamin E, with a membrane derived from MB49 bladder cancer cells. This design leverages homologous targeting for improved tumor accumulation and combines the chemotherapeutic action of DOX with the chemosensitizing function of vitamin E. The resulting nanoparticles demonstrated excellent colloidal stability, high drug-encapsulation efficiency, and efficient cellular internalization, leading to enhanced lysosomal escape, pronounced DNA damage, and synergistic apoptosis induction in vitro. In an orthotopic MB49 bladder cancer model, mPPE@DOX exhibited prolonged blood circulation, superior tumor-targeted delivery, and potent inhibition of tumor growth, which translated into a significant survival benefit. Importantly, this robust antitumor efficacy was achieved with markedly reduced systemic toxicity compared to free DOX. These findings highlighted a promising biomimetic strategy for precise and effective combination therapy against bladder cancer.\n\nID: 42222161\nTitle: Berbamine sensitizes hepatocellular carcinoma to chemotherapy by inhibiting autophagy via modulating SIRT1-mediated acetylation.\nAbstract: Chemoresistance driven by pro-survival autophagy remains a major obstacle in hepatocellular carcinoma (HCC) treatment. Berbamine (BBM), a natural alkaloid with a favorable clinical safety profile, shows potential as an autophagy inhibitor, yet its precise mechanism in HCC remains unclear. Using CCK-8, colony formation, and apoptosis assays, we first demonstrated that BBM synergistically enhanced the efficacy of multiple chemotherapeutic agents (5-FU, Sorafenib, Paclitaxel) against HCC cells in vitro. This synergistic effect was confirmed in an H22 xenograft mouse model in vivo. To investigate the mechanism, we monitored autophagic flux and lysosomal function. Western blot and immunofluorescence analyses revealed that BBM treatment led to the concurrent accumulation of LC3-II and p62, indicating a blockade of late-stage autophagic flux. Further experiments, including LysoTracker staining and assessment of lysosomal protease levels, showed that BBM impaired both autophagosome-lysosome fusion and lysosomal acidification. Mechanistically, we found that BBM downregulated SIRT1 protein expression and reduced the intracellular NAD+/NADH ratio, thereby inhibiting SIRT1 deacetylase activity. This suppression impaired the nuclear translocation and function of the key autophagy transcription factor TFEB, leading to decreased levels of its downstream targets RAB7, CTSB, and CTSD. Crucially, rescue experiments using specific agonists revealed that SIRT1 activation completely reversed all BBM-induced effects, including autophagic flux blockade and downstream protein suppression, whereas TFEB activation only partially rescued the expression of RAB7, CTSB, and CTSD without restoring autophagic flux. This establishes SIRT1 as the primary upstream regulator in this pathway. Our study identifies BBM as a novel autophagy inhibitor that targets the SIRT1-TFEB axis to disrupt autolysosomal fusion and degradation, and nominates it as a promising combinational agent to overcome chemoresistance in HCC.\n\nID: 42217812\nTitle: Novel Gemini surfactant-polyglutamic acid composite system enhances DNA delivery via a \"Dual-Engine\" uptake strategy.\nAbstract: Biophysical barriers, including limited cell uptake routes and inefficient intracellular trafficking, critically restrict the efficacy of cationic gene vectors. Herein, we engineered a ternary plasmid DNA delivery platform based on a newly synthesized sulfonyl-functionalized Gemini surfactant (NGS) via electrostatic assembly with anionic \u03b3-polyglutamic acid (\u03b3-PGA). The optimized ternary complexes NGS-pDNA-PGA (N/P/C ratio of 5:1:1), particularly those incorporating low-molecular-weight \u03b3-PGA (10\u00a0kDa), exhibited favorable transfection efficiency and biocompatibility both in vitro and in vivo. Unlike conventional binary NGS-pDNA complexes, which were restricted to caveolae-mediated endocytosis (CvME) and subsequent endoplasmic reticulum (ER) trafficking, \u03b3-PGA modification introduced a \"dual-engine\" uptake profile, with uptake-pathway inhibition studies supporting the involvement of both caveolae-mediated and clathrin-mediated endocytosis. Further investigation revealed that this multi-route internalization led to programmed intracellular routing, utilizing both ER-dependent trafficking and lysosomal escape pathways to maximize nuclear transport. Transcriptomic analysis provided potential regulating molecules in this process. This study not only presented a high transfection efficiency, biocompatible nanocarrier but also offered a proposed framework of uptake-trafficking regulation dependent routing for next-generation nucleic acid delivery. This study provided valuable insights into the mechanisms driving the enhanced efficacy of NGS nanoparticles, offering a promising platform for transporting-regulated gene delivery.\n\nID: 42217384\nTitle: Humic acid-cation interactions reshape nanoplastic bioaccessibility and mechanistic toxic pathways toward microalgae.\nAbstract: Nanoplastics toxicity is strongly shaped by water-chemistry interactions, yet how coexisting humic acid (HA) and cation jointly restructure toxicity pathways remains poorly resolved. Herein, we systematically examined the aggregation behavior, cellular responses, and bioaccessibility of polystyrene nanoplastics (PSNPs) in Chlorella vulgaris under scenarios involving individual HA, individual cations, and their coexistence. Compared with individual cations (i.e., Na+ or Ca2+), HA-cation coexistence alleviated PSNPs-induced growth inhibition despite promoting PSNPs-algae heteroaggregation and increasing PSNPs bioaccessibility, indicating that bioaccessibility alone did not determine cytotoxicity. This was ascribed to decreased membrane damage (71.5%\u201277.5%), accompanied by reduced downstream photosynthetic impairment (17.5%\u201286.9%) and apoptosis (49.6%\u201262%). In contrast, compared with individual HA, HA-cation coexistence amplified PSNPs toxicity by enhancing particle bioaccessibility (158.7%\u2012201.9%), elevating oxidative stress (7.9%\u201247.5%), and ultimately promoting membrane destabilization (60.2%\u201269.7%). Py-GC/MS quantification confirmed that compared with individual HA, HA-cation coexistence increased PSNPs bioaccessibility from 1.14 \u00b1 0.48 to 3.36 \u00b1 0.39 \u00b5g/104 cells. Structural equation modeling further revealed that increased bioaccessibility acted as an upstream driver of toxicity only when coupled with oxidative stress and membrane damage, highlighting a conditional bioaccessibility-oxidative stress-membrane damage cascade. Together, these findings demonstrate that HA-cation coexistence induces a mechanistic shift in nanoplastic toxicity that cannot be inferred from single-factor experiments. Therefore, we highlight that realistic water-chemistry interactions involving HA and cations should be explicitly incorporated into nanoplastic risk assessment frameworks to avoid biased predictions of ecological impacts in freshwater systems.\n\nID: 42214330\nTitle: Mitochondria-lysosome coupling contributes to lysosome acidification and aging.\nAbstract: Nearly all cellular processes are pH dependent. The acidic pH inside the lysosome (vacuole in yeast) is essential for cellular content degradation, signaling, and autophagy. Defects in lysosome/vacuole acidification are a conserved hallmark of aging and age-related diseases. Traditionally, the lysosome/vacuole is thought to import free protons (H\u207a) from the surrounding neutral cytosol. Here, we uncovered a conserved lysosome/vacuole acidification mechanism from yeast to human involving lysosomal/vacuolar uptake of H+ pumped out by mitochondrial electron transport chain through mitochondria-lysosomes/vacuoles membrane contacts. Aging/senescence-associated disruption of mitochondria-lysosome/vacuole contacts causes lysosomal/vacuolar de-acidification, which can be reversed by either expressing an engineered linker to connect these two organelles or through an asymmetry-dependent rejuvenation process in daughter cells. Preserving lysosomal acidification in senescent human cells prevents the induction of major senescence-associated secretory phenotype factors and restores autophagic flux. These findings reshape our current understanding of the mechanisms underlying lysosomal/vacuolar (de-)acidification in both young and aged/senescent cells.\n\nID: 42213650\nTitle: Transcriptomics of S3 segment in mice: response to type 1 diabetes, SGLT1/2 inhibition, or GLP1 receptor agonism.\nAbstract: Inhibitors of SGLT2 (SGLT2is) and diabetes enhance glucose delivery and reabsorption in late proximal tubule S3 segments. Molecular consequences remain poorly understood. Here, we determined transcriptomic changes in S3 segments of male adult DBA wild-type (WT) and littermate diabetic Akita mice \u00b1 Sglt1 knockout (Sglt1-KO) given vehicle or SGLT2i dapagliflozin for 2 wk, and in Akita mice receiving glucagon-like peptide-1 receptor (GLP1R) agonist (GLP1RA) semaglutide. RNA sequencing was performed in S3 segments isolated by immunostaining-guided laser-capture-microdissection in deep cortex/outer medulla. Among 19,068 detected annotated genes, 838 genes were differentially expressed by SGLT2is in WT (differentially expressed genes; DEGs; P < 0.05) and 1,410 genes in Akita vs. WT. Approximately 34% of SGLT2i-sensitive genes changed in the same direction in Akita. Both maneuvers upregulated pathways of cellular proliferation (confirmed by phospho-Ser10 Histone H3 staining) and cellular response to stress, while downregulating pathways of immune/inflammatory response, cytokine production/receptor signaling, and cell adhesion/migration. Both maneuvers also induced unique responses. Unique pathway responses to SGLT2is in WT included an increase in DNA dealkylation/demethylation and lysosomal acidification, and reduced valine biosynthesis. Differences in SGLT1-dependency of responses to Akita vs. SGLT2is in WT suggested different initiating mechanisms. In Akita, SGLT2is, Sglt1-KO, and GLP1R agonism restored 12%, 18%, and 25% of DEGs, respectively; combined SGLT2i/Sglt1-KO was not synergistic. Akita downregulated whole kidney SGLT1 membrane expression, potentially to limit glucose-induced stress. GLP1RA reduced/restored cellular stress response and proliferation in Akita in S3 segments, associated with enhanced/restored kidney membrane expression of SGLT1. Finally, Akita-sensitive genes unresponsive to any of the three maneuvers were identified that may indicate new therapeutic avenues.NEW & NOTEWORTHY Both SGLT2 inhibition and diabetes increase glucose delivery to late proximal tubule S3 segments. Using transcriptomic mapping in mice, we found that both conditions induce cellular proliferation and stress responses while suppressing inflammatory pathways, but also trigger unique responses. Responses differed in their SGLT1-dependency, suggesting different initiating mechanisms. Diabetes suppressed SGLT1 expression, potentially to limit glucose-induced stress. Glucagon-like peptide-1 receptor (GLP1R) agonism reversed many diabetic transcriptomic changes in S3 segments, including stress response, associated with restored SGLT1 expression.\n\nID: 42209765\nTitle: Mycobacterium tuberculosis MEM39 (Rv1977) hijacks host aldolase A (ALDOA) to subvert immunometabolism to facilitate bacterial intracellular survival.\nAbstract: Mycobacterium tuberculosis (Mtb), the causative agent of tuberculosis (TB), is the leading cause of infectious disease-related death. As a major intracellular pathogen, Mtb can escape clearance by the immune system, but the underlying molecular mechanisms remain incompletely elucidated. Specific genomic regions of deletion (RD)-encoded proteins in virulent Mtb H37Rv have been implicated in modulating pathogenicity and immunity. Here, we report a novel RD15-encoding protein, Rv1977 (a mycobacterial cell wall protein with a size of 39\u2009kDa, named MEM39), which facilitates Mtb survival in macrophages. The survival of the Mtb H37Rv MEM39-deficient strain is reduced in both macrophage and murine infection models. Furthermore, the mycobacterial MEM39 protein binds fructose-diphosphate aldolase A (ALDOA), a key enzyme of glycolysis, thereby impairing ALDOA enzyme activity, disrupting macrophage metabolite flux, and reducing lactate production. The MEM39-ALDOA interaction also suppresses lysosomal acidification; reduces NLRP3 inflammasome activation and the production of proinflammatory cytokines (TNF-\u03b1, IL-6 and IL-1\u03b2); and thereby promotes bacterial survival within macrophages. Disruption of the interaction between MEM39-ALDOA and a cell-penetrating synthetic peptide (VLARYASICQ) significantly suppressed Mtb survival by restoring lactate production, lysosome acidification and proinflammatory cytokine production in both macrophage and mouse infection models. These findings revealed that mycobacterial MEM39 negatively regulates host immune defense through reprogramming ALDOA-mediated glycolysis in macrophages, thereby forming a \"mycobacterial MEM39 virulence factor-glycolysis metabolism-immunity\" regulatory axis. Targeting MEM39 or the MEM39-ALDOA interaction interface holds promise as a new therapeutic strategy against tuberculosis.\n\nID: 42208109\nTitle: Ginseng-derived cholesterol analogues enhance pulmonary siRNA delivery and alleviate allergic asthma.\nAbstract: Asthma patients exhibit elevated airway mucus secretion. Small interfering RNA (siRNA) targeting the mucin MUC5AC delivered by lipid nanoparticles (LNPs) is promising but limited by low transfection efficiency. Protopanaxadiol (PPD), protopanaxatriol (PPT), and ginsenoside Rh2 (GR2) were chosen because their dammarane skeleton preserves membrane-insertion capacity for endosomal escape, whereas bulkier multi-glycosylated ginsenosides adversely affect LNP size and stability. In this study, we designed novel inhaled LNPs incorporating ginseng-derived cholesterol analogs to enhance therapeutic efficacy against asthma. PPD and PPT were used as membrane components to formulate anti-MUC5AC siRNA-loaded LNPs (designated as DLNPs and TLNPs). Flow cytometry and confocal laser scanning microscopy (CLSM) were employed to evaluate the cellular uptake and lysosomal escape of LNPs. An asthmatic mouse model was established to assess therapeutic effects of DLNPs and TLNPs through pathological section analysis and determination of inflammatory cytokine levels. The data showed that these novel formulations enhanced cellular uptake by airway epithelial cells (AECs) and promoted siRNA escape from lysosomes, thereby improving pulmonary delivery efficiency. TLNPs, in particular, demonstrated superior performance. Furthermore, DLNPs and TLNPs exerted multifaceted anti\u2011asthmatic effects in vivo, as evidenced by significant suppression of MUC5AC overexpression in AECs, attenuation of inflammatory cell infiltration, and reduction in the secretion of the critical cytokines IL\u20114 and IL\u201113. Overall, our findings indicate that ginseng-derived PPD and PPT effectively enhance siRNA delivery and mitigate asthma symptoms through dual inhibition of MUC5AC overexpression and airway inflammation. These cholesterol analogs represent promising carrier materials for LNP-based pulmonary therapeutics.\n\nID: 42206503\nTitle: Tea polyphenols increase nanoplastic release from plastic cups but mitigate potential detrimental effects during simulated tea drinking.\nAbstract: The presence of micro- and nanoplastics (MNPs) in daily life raises increasing concerns about their potential health and environmental impacts. However, how food components influence MNP release from packaging materials and the resulting exposure risks remain poorly understood. Here, we investigated the effect of the primary tea polyphenol, epigallocatechin gallate (EGCG), on MNP release from polystyrene cups during a simulated tea-drinking process involving thermal treatments. A surface-enhanced Raman scattering sensor was developed to quantify released plastic particles in situ using EGCG-based luminescent metal-phenolic network labeling. The released particles were identified primarily as nanoplastics, and the presence of EGCG significantly (P < 0.05) increased MNP release, particularly during microwave heating and most prominently upon repeated cup use. Interestingly, EGCG increased the MTT response of differentiated Caco-2 cells exposed to released NPs in a dose-dependent manner, suggesting a potential mitigation of NP-associated cytotoxicity under the tested in vitro conditions. This study provides new insight into the dynamic interactions between food components and plastic packaging during realistic consumption scenarios, revealing an overlooked pathway influencing human exposure to nanoplastics. The findings expand the current understanding of contaminant release mechanisms at the food-environment interface and inform future strategies for exposure mitigation and sustainable material design to ensure food safety and protect environmental and public health.\n\nID: 42199981\nTitle: Phytochemical Monomers Derived from Traditional Chinese Medicine May Prevent and Treat Atherosclerosis by Modulating the Macrophage Mitochondrial-Lysosomal Senescence Axis.\nAbstract: The pathogenesis of atherosclerosis (AS) is evolving from a lipid-centric view to a paradigm of immunosenescence. Stress-induced senescence of plaque macrophages is associated with inflammation and instability via the senescence-associated secretory phenotype (SASP). Dysfunction of the integrated \"mitochondria-lysosome senescence axis\" is thought to play a key role in maintaining this senescent state, which correlates with lipid overload, impaired efferocytosis, and fibrous cap degradation. Multi-targ et monomers from Traditional Chinese Medicine (TCM) such as quercetin, Tanshinone IIA, berberine, and baicalein have been shown to modulate senescent macrophages, potentially via this axis. Proposed mechanisms include inhibiting p38 MAPK/p16 signaling, reducing scavenger receptor-mediated lipid uptake, enhancing cholesterol efflux, suppressing the NF-\u03baB/NLRP3 inflammasome, promoting efferocytosis via TAM receptors, and restoring metabolic support for lysosomal acidification. This review synthesizes the role of the mitochondria-lysosome axis in AS and highlights the potential of TCM monomers to stabilize plaques, providing a novel framework for therapeutic development.\n\nID: 42197399\nTitle: Micro/Nanoplastics and Periodontitis: An Environmental Microbiology Perspective on Oral Retention and Systemic Risk.\nAbstract: Micro- and nanoplastics (MNPs) have now been detected in human blood, placenta, and arterial tissue, yet the oral cavity has received strikingly little mechanistic attention despite serving as a primary portal of environmental exposure and a local site of polymer generation from dental and oral-care materials. This narrative review addresses that gap from an environmental microbiology perspective, synthesizing recent literature on periodontal disease, chronic low-grade inflammation, oral biofilms, dental materials, microbial-plastic interactions, and systemic chronic disease risk. Unlike prior reviews, we apply an explicit three-tier evidentiary framework (established, plausible, unproven) that distinguishes what is directly demonstrated from what is biologically plausible but unproven, and we situate the periodontal environment specifically as a particle-retention and inflammatory-amplification niche. The strongest direct oral evidence shows that human dental calculus harbors at least 26 microplastic types, dominated by polyamide (41.4%), polyethylene (32.7%), and polyurethane (7.0%). Polyethylene isolated from calculus induces cytotoxicity, apoptosis, impaired migration, NF-\u03baB activation, and upregulation of IL-1\u03b2 and IL-6 in human gingival fibroblasts. From a microbiological standpoint, oral organisms actively degrade methacrylate dental polymers, and the degradation products of these polymers reciprocally modulate oral bacterial virulence gene expression. Across experimental systems, MNPs activate oxidative stress, inflammasome signaling, macrophage polarization, and barrier dysfunction, pathways that overlap extensively with periodontal pathobiology. Adjacent environmental microbiology demonstrates that plastic-associated biofilms enhance extracellular polymeric substance production, quorum sensing, pathogen persistence, and antibiotic resistance gene transfer, supporting a plausible but not yet validated oral plastisphere within plaque and calculus. We argue that periodontitis should be reconceptualized as a chronically inflamed particle-processing interface that may increase local MNP retention, cellular reactivity, and systemic inflammatory spillover, with implications for cardiovascular, metabolic, and other chronic disease risk pathways. Current evidence does not yet prove that environmental MNP exposure causes human periodontitis, and that evidentiary boundary is maintained throughout. A priority research agenda is proposed, centered on contamination-controlled subgingival biomonitoring stratified by periodontal status, spatially resolved multi-species biofilm models, polymer source attribution, and longitudinal clinical studies linking oral plastic burden to inflammatory and systemic outcomes.\n\nID: 42188099\nTitle: Low Shear Stress Promotes Atherosclerosis by Mediating Pathological Accumulation of Endothelial Lipid Droplets via the KLF4/TFEB/ATP1A1 Axis.\nAbstract: Atherosclerosis preferentially develops at arterial regions exposed to low shear stress (LSS), highlighting the critical role of local hemodynamic forces in disease initiation and progression. Emerging evidence indicates that endothelial lipid metabolism is a key determinant of vascular homeostasis; however, whether LSS directly regulates endothelial lipid droplets' (LDs) dynamics remains unclear. In particular, the mechano-transduction pathways linking shear stress to lysosome-mediated lipid processing within the endothelium have yet to be defined. Complementary in vitro flow systems and in vivo atheroprone models were employed to examine the effects of LSS on endothelial lipid metabolism. Endothelial LDs accumulation, lysosome-dependent lipophagy, and atherosclerotic lesion development were systematically assessed under LSS conditions. Mechanistically, molecular profiling and rapamycin-mediated functional rescue were conducted to delineate the role of the KLF4/TFEB/ATP1A1 signaling axis in LSS-induced impairment of lysosome-dependent lipophagy. We found that LSS induced pathological accumulation of LDs in vascular endothelial cells, accompanied by a marked suppression of lysosome-dependent lipophagy. Elucidation of the mechanism showed that LSS downregulated the shear-responsive transcription factor KLF4, resulting in aberrant phosphorylation of transcription factor EB (TFEB) and impaired TFEB nuclear translocation. Consequently, the TFEB transcriptional program governing lysosomal function was disrupted, including reduced expression of the TFEB target ATP1A1, leading to defective lysosomal acidification and blockade of lipid autophagic flux. Restoration of the KLF4/TFEB/ATP1A1 axis reactivated lipophagy, alleviated endothelial lipid burden, and significantly attenuated atherosclerotic lesion development. Our findings demonstrate that disruption of the KLF4/TFEB/ATP1A1 signaling pathway mediates LSS-induced impairment of endothelial lipophagy, thereby driving pathological LDs accumulation. This highlights the potential of restoring this axis as a therapeutic strategy to attenuate atherosclerotic progression.\n\nID: 42177862\nTitle: Antimicrobial peptide WK-13-3D inhibits triple-negative breast cancer by blocking autophagic flux through inhibiting the AKT/mTOR pathway and targeting binding immunoglobulin protein (BiP).\nAbstract: To investigate the antitumor efficacy of a novel antimicrobial peptide WK-13-3D, against triple-negative breast cancer (TNBC) and elucidate its mechanism of action via targeting binding immunoglobulin protein BiP and modulating the AKT/mTOR pathway to disrupt autophagy-lysosome homeostasis. TNBC cell lines MDA-MB-231 and MDA-MB-468 were employed as in vitro models. Cell viability and clonogenic potential were assessed using CCK-8 and colony formation assays. Autophagy-related proteins (LC3-II/I, p62) and phosphorylation levels of key AKT/mTOR pathway components were analyzed by Western blotting. Autophagosome formation was visualized via transmission electron microscopy and immunofluorescence. Autophagic flux was monitored using mCherry-GFP-LC3 tandem fluorescent adenovirus. Lysosomal acidification was evaluated by LysoTracker Red and acridine orange (AO) staining. Functional rescue experiments were conducted using the AKT activator SC79. The in vivo antitumor activity of WK-13-3D was validated in a nude mouse xenograft model. WK-13-3D significantly suppressed TNBC cell viability and clonogenicity. Mechanistically, WK-13-3D concurrently inhibited AKT/mTOR signaling and directly bound to BiP, triggering endoplasmic reticulum (ER) stress. Notably, WK-13-3D treatment led to autophagic flux blockade, evidenced by autophagosome accumulation (increased LC3-II/I ratio) and impaired degradation of the autophagic substrate p62, without compromising lysosomal acidification or hydrolytic function. Activation of the AKT/mTOR pathway partially reversed WK-13-3D-induced autophagy dysregulation, whereas BiP overexpression restored autophagic flux and enhanced lysosomal activity. These dual-targeting effects converged to exert a potent and enhanced antitumor response. WK-13-3D disrupts autophagy-lysosome crosstalk in TNBC via coordinated inhibition of AKT/mTOR signaling and BiP-mediated ER stress, representing a promising lead candidate that provides mechanistic insights for TNBC treatment and warrants further preclinical investigation.\n\nID: 42176698\nTitle: Mitochondrial dysfunction and DNA damage reveal nanoplastic-induced cytotoxicity in the sea cucumber Apostichopus japonicus.\nAbstract: Nanoplastics (NPs), as an emerging class of pollutants, have become pervasive in marine environments due to the fragmentation of larger plastic debris and intentional production for industrial applications. In this study, we investigated the cytotoxic effects of NPs on intestinal and respiratory tree cells of the sea cucumber Apostichopus japonicus, focusing on oxidative stress, mitochondrial integrity, and DNA damage. Cells were exposed to 100\u202fnm NPs dispersed in culture media at concentrations of 0.1, 1.0 and 10.0\u202f\u03bcg\u202fmL-1 for 24\u202fh, with untreated cells serving as the control. Transmission electron microscopy revealed progressive cell membrane rupture, extensive vacuolation, and the presence of bilayered autophagy-like structures and monolayered lysosome-like vesicles following NP exposure. TUNEL assays revealed a significant increase in TUNEL-positive DNA fragmentation across PS-NP exposure levels, suggesting enhanced apoptosis-like cell death. A 1.0-1.4-fold increase in ROS production confirmed that NPs induced significant oxidative stress. Mitochondrial disruption was evident by increased ADP levels and reduced ATP content, oxygen consumption rate, and activities of respiratory chain complex I-V, suggesting impaired oxidative phosphorylation. Transcriptomic analysis further supported the involvement of mitochondrial pathways in NP-induced apoptosis. Moreover, after 24\u202fh of exposure, both olive tail moment (with an 8.0-11.8-fold increase) and DNA-protein crosslinking (25.7-30.2%) were markedly elevated, even at the lowest NP concentration of 0.1\u202f\u03bcg\u202fmL-1, demonstrating substantial genotoxic effects. Overall, NPs induced cytotoxicity and apoptosis in A. japonicus cells in a dose-dependent manner, with time-dependent changes in mitochondrial function. These findings highlight the sensitivity of A. japonicus cells to nanoplastic exposure and propose cellular response indicators such as ROS accumulation, ATP/ADP imbalance, and MPTP opening as potential biomarkers for ecological risk assessment in marine benthic systems.\n=======================================================\n\n### [CUSTOM DATAPOINTS]\nCRITICAL EXTRACTION DIRECTIVE: You MUST extract the following custom datapoints as root-level key/value pairs inside your final JSON block:\n- \"suggested_experiments\": generate 1-3 suggested experiments\n- \"suggested_studies\": generate 1-3 suggested studies\n- \"swansons_literature_based_discovery_candidates\": You are an advanced Literature-Based Discovery (LBD) system executing Swanson\u2019s complementary-but-disjoint (A-B-C) model.

Inherent differences in these culture/exposure modalities, such as particle behavior and deposited dose, likely affect cellular responses. To investigate this, we exposed submerged human bronchial epithelial cells (BEAS-2B) to polystyrene (PS) MNPs vs. aerosol exposure of ALI cultures. First, submerged bronchial epithelial cells (BEAS-2B) were exposed to suspensions of PS particles (50\u2009nm or 1\u2009\u00b5m) in four different applied concentrations (0.79-50\u2009\u00b5g/cm2; 24\u2009h). Second, BEAS-2B cells were cultured at ALI and exposed in a cloud system to PS 1\u2009\u00b5m particles (deposited dose: 55.4\u2009\u00b5g/cm2; 24\u2009h). Toxicity readouts focused on cytotoxicity (LDH release), inflammation (IL-8 release and transcriptional activation of inflammatory genes), and oxidative stress (DCFH-DA assay, antioxidant gene expression, and assessment of reduced/oxidized glutathione). In both models, PS exposure did not induce cell death, or an antioxidant response. However, NF-\u03baB transcriptional activity was strongly upregulated in submerged cells in response to both sizes of PS particles in a dose-dependent manner. Gene expression of CXCL1, CXCL2, and CXCL8 increased up to 7-fold after PS microplastic exposure (50\u2009\u00b5g/cm2) in the submerged model (which was less pronounced in response to PS nanoplastics) and 2-fold in the ALI model. In contrast, IL-8 secretion increased 1.6-fold for the ALI, but not the submerged model. Overall, both exposure modalities revealed an inflammatory response toward PS MNPs although with differences, likely due to significant differences in deposited dose. Very small plastic particles, called microplastics and nanoplastics (MNPs), are present in the air and can be inhaled into the lungs. To study possible health effects, scientists often expose lung cells to these particles in liquid (submerged) culture systems. However, this does not closely match how people are exposed through breathing. This study used a traditional liquid-based method and a more realistic system that exposes lung cells to plastic particles through the air. More specifically, human lung cells were exposed to polystyrene (PS) plastic particles of different sizes using either liquid exposure or an air\u2013liquid interface system, where particles were delivered as an aerosol, similar to inhalation. The researchers looked for signs of cell damage, inflammation, and oxidative stress. The results showed that the plastic particles did not kill the cells and did not cause oxidative stress in either exposure method. However, both methods caused signs of inflammation, which is a normal response of the body to foreign substances. In the liquid-based system, inflammation-related genes were strongly activated. In the air-exposed system, gene activation was weaker, but cells released higher levels of an inflammatory signaling protein. Importantly, the air-based exposure better reflects how people actually breathe in particles and avoids some problems linked to liquid-based testing. This study shows that there are differences in cellular responses to MNPs depending on the dose, particle behavior and culture system, which are all connected to each other.\n --- END ACTUAL ABSTRACT FOR 42417458 ---\n\n- ERROR: You cited ID: 40598479 for the quote: \"PS-NP exposure hampered p62 degradation, leading to LC3B accumulation and decreased cathepsin B and D activity.\"\n FACT: Quote was found in context but NOT in the specific abstract mapped to ID '40598479'.\n \n Below is the complete, true text of ID 40598479 that you MUST read. \n Find a valid, verbatim, character-perfect sentence inside this exact block to cite instead, or change your claim to align with what this text actually says:\n \n --- BEGIN ACTUAL ABSTRACT FOR 40598479 ---\n ID: 40598479\nTitle: Cancer cell membrane-camouflaged pH-responsive nanoparticles for enhancing siRNA effect and synergistic anti-tumor therapy.\nAbstract: RNA-based therapies, especially small interfering RNA (siRNA), have attracted extensive attention for tumor treatment. However, most siRNA can't exert a therapeutic effect due to a lack of targeting to tumor cells and entrapment in lysosomes upon administration. To address the challenges associated with siRNA delivery, a delivery system was developed using zinc oxide nanoparticles (ZnO NPs) coated with cancer cell membranes. ZnO nanoparticles (ZnO NPs) have been recognized as effective pH-responsive nanoparticles and are widely used in the development of pH-responsive drug delivery systems. The ZnO NPs were combined with chitosan to encapsulate siRNA, allowing for dissolution in acidic lysosomes and the subsequent release of siRNA and chitosan complexes. The dissolution of ZnO NPs would also disrupt lysosomes, facilitating the escape of siRNA and enhancing its gene silencing effect. However, the chitosan and ZnO NPs nano-complexes (CS/ZnO@siRNA) were unstable in solution and lacked a specific targeting effect for tumor cells. Thus, a homologous cancer cell membrane was coated onto the nanoparticles, which has been shown to be an effective strategy for enhancing their stability and targeting capabilities. Moreover, ZnO NPs not only dissolve in acidic lysosomes to enhance the efficacy of siRNA but also elevate oxidative stress levels in cells, leading to the induction of cellular apoptosis. It was demonstrated both in vitro and in vivo that the ZnO NPs could synergistically combine with the anti-tumor siRNA (siSurvivin) to inhibit the growth of the 4T1 tumor. Altogether, the developed drug delivery system (CCM-CS/ZnO@siSurvivin) offers a new strategy for enhancing the therapeutic effect of siRNA, while synergistically inhibiting tumor growth.

However, the underlying mechanism for the toxic effects of nanoplastics on the BBB remain poorly understood. In this study, we explored the toxic effects of polystyrene nanoplastic (PSNP) on brain microvascular endothelial cells (BMECs), one of the most critical components for maintaining BBB integrity. Our results revealed that PSNP specifically accumulate in the endolysosomal system following their internalization by BMECs. This accumulation disrupts lysosomal function and blocks endolysosomal pathways, ultimately triggering methuosis-a unique form of cell death characterized by extensive cytoplasmic vacuolization. Although the endosomal sorting complexes required for transport (ESCRT) system is naturally activated as a cellular defense mechanism, it is insufficient to repair PSNP-induced lysosomal membrane damage. By enhancing ESCRT activity, we effectively restored lysosomal function, thereby preventing cellular methuosis and preserving BBB integrity. Therefore, our findings provide crucial insights into the mechanisms underlying PSNP-induced BBB disruption by focusing on methuosis in endothelial cells. These insights hold important implications for environmental toxicology and public health in the context of global plastic pollution.\n --- END ACTUAL ABSTRACT FOR 40782538 ---\n\n- ERROR: You cited ID: 40532836 for the quote: \"Furthermore, co-exposure to PS-MPs and MEHP induced lysosomal membrane permeabilization (LMP), which significantly impaired lysosomal-mediated lipid degradation, thereby exacerbating lipid metabolism dysfunction.\"\n FACT: Strict Misquote Detected!

However, most existing research has focused on single exposure, which is not consistent with the actual exposure circumstance. In this study, single and co-exposure animal model were established. C57/BL6J mice were exposed to corn oil, 20 mg/kg PS-MPs, 200 mg/kg DEHP and PS-MPs + DEHP for 28 days. The HE staining showed more serious seminiferous epithelium disorganization in co-exposed mice, indicating that PS-MPs and DEHP co-exposure could aggravate testicular injury. Compared with control group, integrative analysis of transcriptomics and proteomics revealed that PPAR\u03b3 pathway played a crucial role in PS-MPs and DEHP co-exposure induced testis injury. In vitro, spermatocytes (GC-2) and leydig cells (TM3) were exposed to 50 \u03bcM MEHP, 10 mg/L PS-MPs and PS-MPs + MEHP for 48 h. Though PS-MPs and MEHP single exposure also triggered oxidative stress and PPAR pathway, the protein levels showed more remarkable difference in co-exposure group. Furthermore, co-exposure to PS-MPs and MEHP induced lysosomal membrane permeabilization (LMP), which significantly impaired lysosomal-mediated lipid degradation, thereby exacerbating lipid metabolism dysfunction in testicular cells. Treatment with N-Acetylcysteine (NAC) and knockdown of fatty acid-binding protein (FABP4) restored lipophagy flux and reduced lipid droplets deposition. Overall, co-exposure of PS-MPs and DEHP has synergistic toxic effect, inducing oxidative stress, PPAR\u03b3 activation and lipophagy blockage, finally resulting in unbalanced lipid metabolism and testicular damage.\n --- END ACTUAL ABSTRACT FOR 40532836 ---\n\n- ERROR: You cited ID: 42206503 for the quote: \"The released particles were identified primarily as nanoplastics, and the presence of EGCG significantly (P < 0.05) increased MNP release.\"\n FACT: Strict Misquote Detected!

However, how food components influence MNP release from packaging materials and the resulting exposure risks remain poorly understood. Here, we investigated the effect of the primary tea polyphenol, epigallocatechin gallate (EGCG), on MNP release from polystyrene cups during a simulated tea-drinking process involving thermal treatments. A surface-enhanced Raman scattering sensor was developed to quantify released plastic particles in situ using EGCG-based luminescent metal-phenolic network labeling. The released particles were identified primarily as nanoplastics, and the presence of EGCG significantly (P < 0.05) increased MNP release, particularly during microwave heating and most prominently upon repeated cup use. Interestingly, EGCG increased the MTT response of differentiated Caco-2 cells exposed to released NPs in a dose-dependent manner, suggesting a potential mitigation of NP-associated cytotoxicity under the tested in vitro conditions. This study provides new insight into the dynamic interactions between food components and plastic packaging during realistic consumption scenarios, revealing an overlooked pathway influencing human exposure to nanoplastics. The findings expand the current understanding of contaminant release mechanisms at the food-environment interface and inform future strategies for exposure mitigation and sustainable material design to ensure food safety and protect environmental and public health.\n --- END ACTUAL ABSTRACT FOR 42206503 ---\n\n- ERROR: You cited ID: 42307976 for the quote: \"Mechanistically, corona-bound LYZ engaged Toll-like receptor 4 and activated a PGRN-LXR\u03b1 signaling axis, thereby increasing lysosomal acidification-dependent efferocytosis.\"\n FACT: Strict Misquote Detected!

Although inhaled NPs rapidly acquire a protein corona that shapes their bioactivity, the consequences of this process in cancer-susceptible lungs remain unclear. Here, we investigated whether NPs form a disease-specific pathogenic protein corona in lung adenocarcinoma that rewires immune signaling and accelerates tumor progression. Polyethylene terephthalate (PET) NPs were generated by mechanical fragmentation and extensively characterized. In tumor-bearing mice, inhaled PET NPs accelerated tumor growth relative to controls. Proteomic analysis of PET NPs incubated with bronchoalveolar lavage fluid from patients with lung adenocarcinoma identified lysozyme (LYZ) as a selectively enriched corona component associated with tumor stage and metastasis. Corona formation induced conformational remodeling of LYZ, enhanced its enzymatic activity, and prolonged its membrane retention. Mechanistically, corona-bound LYZ engaged Toll-like receptor 4 and activated a PGRN-LXR\u03b1 signaling axis, thereby increasing lysosomal acidification-dependent efferocytosis, promoting M2 macrophage polarization, and reducing CD8+ T-cell infiltration. In vivo, AAV9-mediated knockdown of LYZ or PGRN attenuated PET NP-induced efferocytosis, reversed immunosuppressive reprogramming, restored CD8+ T-cell infiltration, and suppressed tumor growth, demonstrating the functional requirement for this corona pathway. These findings establish disease-derived PET NP coronas as active nano-bio interfaces that connect environmental PET NP exposure with efferocytosis-driven immune evasion in lung adenocarcinoma. This work provides a mechanistic link between airborne NPs and tumor progression in susceptible hosts and highlights corona-mediated signaling as a potential therapeutic target and environmental health concern.\n --- END ACTUAL ABSTRACT FOR 42307976 ---\n\n- ERROR: You cited ID: 42163812 for the quote: \"Our study demonstrates that RS-FS self-assembles into nanospheres or nanofibers in response to stimuli and enables tumor cell-specific lysosome disruption, resulting in enhanced drug release, autophagic flux blockade, and antitumor activities of diverse therapeutics in HCC mice.\"\n FACT: Strict Misquote Detected!

Here, we demonstrate that a chimeric peptide (RS-FS), consisting of HCC-targeting RS and nanostructure-forming motifs (FS), self-assembles into nanospheres at neutral pH and transforms into nanofibers under acidic and reductive conditions. These nanofibers specifically localize to tumors and disrupt tumor cell lysosomes, thus enhancing doxorubicin's activity in human HCC cells in vitro and orthotopic HCC mice in vivo after RS-FS-doxorubicin treatment. Importantly, intravenous RS-FS potentiated oral Lenvatinib's antitumor activity up to 61-fold, and eradicated tumors in orthotopic HCC mice via HCC cell-specific lysosome disruption. Potent antitumor effects were also achieved with intravenous RS-FS and oral Epimedium brevicornu Maxim. -derived extracellular vesicles in orthotopic HCC mice, with markedly reduced tumor growth and increased cytotoxic T infiltration, in which RS-FS-mediated lysosome disruption promoted drug release and autophagic flux blockade. Our study demonstrates that RS-FS self-assembles into nanospheres or nanofibers in response to stimuli and enables tumor cell-specific lysosome disruption, resulting in enhanced drug release, autophagic flux blockade, and antitumor activities of diverse therapeutics in HCC mice, and thus provides a generalizable peptide adjuvant for sensitizing HCC-targeted therapeutics.\n --- END ACTUAL ABSTRACT FOR 42163812 ---\n\n- ERROR: You cited ID: 41247156 for the quote: \"In a chloroquine(CQ)-induced lysosomal injury model and mice model, they effectively restored lysosomal pH, enhanced autophagy... cleared amyloid precursor protein (APP) and phosphorylated tau (p-tau) proteins.\"\n FACT: Ellipses (...) are strictly forbidden.

Mesenchymal stem cell-derived nanovesicle-poly(lactic-coglycolic acid) nanoparticles (MSC-PLGA-NPs) were prepared via sonication-loading. Blood-brain barrier (BBB) penetration was evaluated using in vitro transwell models and in vivo mouse models. Lysosomal function, autophagy, pathological protein clearance, and anti-inflammatory effects were assessed using various cellular and molecular biology techniques. MSC-PLGA-NPs demonstrated 2.3-fold higher BBB penetration efficiency compared to PLGA alone. In a chloroquine(CQ)-induced lysosomal injury model and mice model, they effectively restored lysosomal pH, enhanced autophagy (reducing LC3-II/I ratio by 0.4-fold and p62 expression by 52%), cleared amyloid precursor protein (APP) and phosphorylated tau (p-tau) proteins, and inhibited IL-6 and TNF-\u03b1 without hepatorenal toxicity. These results demonstrate that MSC-PLGA-NPs, a novel multifunctional nanoparticle platform, synergistically integrates the BBB penetration capability of MSC-NVs and the lysosomal acidification function of PLGA. The synergistic combination represents a pioneering \"delivery-repair-clearance\" integrated strategy for AD therapy. Offering significant advantages over single-component approaches, MSC-PLGA-NPs provide a promising preclinical candidate and new insight into lysosome-targeted nanomedicines for neurodegenerative diseases.\n --- END ACTUAL ABSTRACT FOR 41247156 ---\n\n- ERROR: You cited ID: 40943214 for the quote: \"We demonstrate that inorganic MSNs cause significant changes in lysosomal function by altering lysosomal content and cathepsin levels, without triggering lysosomal membrane permeabilization.\"\n FACT: Strict Misquote Detected!

However, their interactions with intracellular organelles, particularly lysosomes, are not yet fully understood. This study delineates the differential effects of two widely used nanocarriers-mesoporous silica (MSNs) and albumin (ANPs) nanoparticles-on lysosomal biology, with a focus on the expression and activity of cathepsins (CtsB and CtsD), which are key proteases involved in protein degradation and maintaining cellular balance. These two types of nanoparticles, differing in their material and degradability, exhibit distinct behaviors inside the cell. We demonstrate that inorganic MSNs cause significant changes in lysosomal function by altering lysosomal content and cathepsin levels, without triggering lysosomal membrane permeabilization-a typical response to organic particle stress. In contrast, ANPs-which are susceptible to lysosomal cathepsin degradation-induce milder changes in cathepsin expression and maintain lysosomal integrity. Our results highlight that the composition of nanocarriers plays a pivotal role in modulating lysosomal protease activity and maintaining overall cellular homeostasis, highlighting the importance of these parameters in the rational design of drug delivery platforms.\n --- END ACTUAL ABSTRACT FOR 40943214 ---\n\n\n\u2705 PASSED (DO NOT CHANGE THESE):\n- \"In vitro, AcNPs effectively restored lysosomal pH, enhanced autophagic clearance of \u03b1Syn, improved mitochondrial function, and rescued A30P \u03b1Syn-induced cytotoxicity.\" (Source: 42033266)\n- \"These nanomaterials were developed to locally acidify impaired lysosomes and restore their degradative capacity.\" (Source: 42033266)\n- \"The capacity of the nanoparticles to restore function to stressed lysosomes was confirmed by their ability to reacidify lysosomes, restore cathepsin B activity, and increase the levels of active cathepsin D.\" (Source: 41533007)\n- \"Moreover, PS NPs impaired lysosomal degradation function, evidenced by reduced CTSB and CTSD protein levels.\" (Source: 40665500)\n- \"Western blotting and immunofluorescence indicated that PS-NPs induced pyroptosis, disrupted autophagic flux, and lowered protein levels involved in autophagosome-lysosome fusion, both in vivo and in vitro.\" (Source: 40474178)\n- \"Here, we provide compelling evidence that \u03b1-synuclein preformed fibrils (\u03b1-syn PFF) impair lysosomal acidification in microglia, leading to defective autophagic flux and disrupted \u03b1-syn degradation.\" (Source: 42374161)\n- \"Enhancing lysosomal acidification and degradative function may help re-establish effective autophagic flux and improve disease outcomes.\" (Source: 42456394)\n- \"Unique pathway responses to SGLT2is in WT included an increase in DNA dealkylation/demethylation and lysosomal acidification, and reduced valine biosynthesis.\" (Source: 42213650)\n- \"We also found that acidic nanoparticles rescued lysosomal acidification and relieved the degenerative changes of Nd-PSG.\" (Source: 40413758)\n- \"RID-B demonstrated potent lysosomal neutralization and inhibited autophagic flux near its half-maximal inhibitory concentration.\" (Source: 40845958)\n- \"At the cellular level, loss of ClC-3 disrupts lysosomal acidification, resulting in a blockade of autophagic flux.\" (Source: 42229818)\n\n\nINSTRUCTION: Study the actual abstracts provided.

While oligonucleotide-based gene therapy holds promise for precision intervention, its clinical translation is hindered by inefficient cellular delivery and rapid lysosomal degradation. Here, we identified miRNA-223 as a pivotal regulator of IVDD, where its overexpression mitigated the inflammatory extracellular matrix (ECM) metabolic imbalance in NP cells in vitro. To overcome delivery barriers in vivo, we engineered an injectable multifunctional cell-penetrating peptide (CPP), R9-DOPA-DBCO, which spontaneously self-assembles with azido-modified miRNA-223 via bioorthogonal click chemistry to form nanocomplexes (R9-DOPA-miRNA223). These nanoparticles not only exhibited superior cell membrane penetration and lysosomal escape capabilities but also exhibited significant therapeutic efficacy in mitigating NP cell pyroptosis and restoring ECM metabolic homeostasis via the MKNK2/eIF4E/NOD-like signaling pathway, concomitantly attenuating IVDD progression in rat models. This direct and efficient delivery strategy not only has transformative potential for IVDD therapy but also broadens the conceptual and methodological framework for precision miRNA-based therapeutics.\n --- END ACTUAL ABSTRACT FOR 42398422 ---\n\n- ERROR: You cited ID: 42413336 for the quote: \"Notably, 80 nm PS MNPs elicited stronger early toxicity.\"\n FACT: Strict Misquote Detected!

Here, we compared two red-fluorescent polystyrene spherical MNP preparations with nominal diameters of 80\u202fnm and 200\u202fnm, respectively, with red-fluorescent polyacrylonitrile Fiber MNPs (approximately 200\u202fnm in diameter and 2-3 \u03bcm in length) to define their effects on the corneal epithelium and ocular surface functional unit. In vitro, all MNP types were internalized by human corneal epithelial (HCE-T) cells with perinuclear accumulation and induced dose- and time-dependent cytotoxicity, including reduced viability, increased ROS, elevated TUNEL positivity, ZO-1 downregulation, and impaired epithelial migration; notably, 80\u202fnm PS MNPs elicited stronger early toxicity. In vivo, chronic topical exposure produced corneal epithelial damage, tear-film instability, conjunctival goblet-cell depletion, reduced corneal nerve density, and lacrimal gland inflammatory activation. Live imaging and scanning electron microscopy confirmed deposition, with Fiber MNPs showing surface embedding and disruption of corneal epithelial microvillar microarchitecture. Transcriptomic profiling with in vitro/in vivo validation showed enrichment of MAPK signaling and activation-associated changes in the MAP3K8-ERK/JNK/p38 axis, accompanied by a sustained pro-inflammatory transcriptional program, with more persistent inflammatory signaling in the Fiber MNP group. Together, these findings demonstrate particle type- and morphology-associated ocular surface toxicity of MNPs and support considering particle morphology together with polymer identity, size, and particle number in future ocular health risk assessment.\n --- END ACTUAL ABSTRACT FOR 42413336 ---\n\n\n\u2705 PASSED (DO NOT CHANGE THESE):\n- \"In vitro, AcNPs effectively restored lysosomal pH, enhanced autophagic clearance of \u03b1Syn, improved mitochondrial function, and rescued A30P \u03b1Syn-induced cytotoxicity.\" (Source: 42033266)\n- \"These nanomaterials were developed to locally acidify impaired lysosomes and restore their degradative capacity.\" (Source: 42033266)\n- \"The capacity of the nanoparticles to restore function to stressed lysosomes was confirmed by their ability to reacidify lysosomes, restore cathepsin B activity, and increase the levels of active cathepsin D.\" (Source: 41533007)\n- \"Moreover, PS NPs impaired lysosomal degradation function, evidenced by reduced CTSB and CTSD protein levels.\" (Source: 40665500)\n- \"Western blotting and immunofluorescence indicated that PS-NPs induced pyroptosis, disrupted autophagic flux, and lowered protein levels involved in autophagosome-lysosome fusion, both in vivo and in vitro.\" (Source: 40474178)\n- \"Here, we provide compelling evidence that \u03b1-synuclein preformed fibrils (\u03b1-syn PFF) impair lysosomal acidification in microglia, leading to defective autophagic flux and disrupted \u03b1-syn degradation.\" (Source: 42374161)\n- \"Enhancing lysosomal acidification and degradative function may help re-establish effective autophagic flux and improve disease outcomes.\" (Source: 42456394)\n- \"Unique pathway responses to SGLT2is in WT included an increase in DNA dealkylation/demethylation and lysosomal acidification, and reduced valine biosynthesis.\" (Source: 42213650)\n- \"We also found that acidic nanoparticles rescued lysosomal acidification and relieved the degenerative changes of Nd-PSG.\" (Source: 40413758)\n- \"RID-B demonstrated potent lysosomal neutralization and inhibited autophagic flux near its half-maximal inhibitory concentration.\" (Source: 40845958)\n- \"At the cellular level, loss of ClC-3 disrupts lysosomal acidification, resulting in a blockade of autophagic flux.\" (Source: 42229818)\n- \"Key findings reveal that the BGNs are mainly internalized by active transport mechanisms and are entrapped in endosomes/lysosomes, limiting their ability to exert their full intracellular therapeutic potential.\" (Source: 40963485)\n- \"Across experimental systems, MNPs activate oxidative stress, inflammasome signaling, macrophage polarization, and barrier dysfunction, pathways that overlap extensively with periodontal pathobiology.\" (Source: 42197399)\n- \"Defects in lysosome/vacuole acidification are a conserved hallmark of aging and age-related diseases.\" (Source: 42214330)\n- \"Notably, once the NPs enter cells and become sequestered within lysosomes, they induce the upregulation of the V-ATPase subunits ATP6V1A/ATP6V1G1.\" (Source: 41896932)\n- \"These nanofibers specifically localize to tumors and disrupt tumor cell lysosomes, thus enhancing doxorubicin's activity in human HCC cells in vitro and orthotopic HCC mice in vivo after RS-FS-doxorubicin treatment.\" (Source: 42163812)\n- \"PS-NP exposure hampered p62 degradation, leading to LC3B accumulation and decreased cathepsin B and D activity.\" (Source: 40607257)\n- \"The data showed that these novel formulations enhanced cellular uptake by airway epithelial cells (AECs) and promoted siRNA escape from lysosomes, thereby improving pulmonary delivery efficiency.\" (Source: 42208109)\n\n\nINSTRUCTION: Study the actual abstracts provided.

Evidence confirms that nanoplastics and other environmental contaminants frequently induce lysosomal dysfunction, including alkalization, blockade of autophagic flux, and cathepsin inhibition. The proposal that AcNPs could be repurposed to mitigate nanoplastic-induced toxicity is mechanistically plausible given the convergent pathways of lysosomal impairment, although direct experimental evidence of AcNP application to nanoplastic-induced lysosomal damage in vivo is currently limited.\n\n### [ABSTRACT & REWRITTEN CLAIM]\nLysosomal integrity is a critical requirement for maintaining cellular homeostasis, particularly in the clearance of protein aggregates and lipid metabolism. Environmental contaminants, such as polystyrene nanoplastics, frequently target the endolysosomal system, causing pH elevation, cathepsin inhibition, and autophagic flux stagnation. Lysosome-acidifying nanoparticles (AcNPs), originally developed to treat lysosomal storage disorders and neurodegenerative conditions like Parkinson's disease, effectively reverse these lysosomal deficits. The synthesis of this evidence indicates that AcNPs may serve as a cross-disciplinary solution for restoring lysosomal function compromised by chronic nanoplastic exposure.\n\n### [INTRODUCTION & JUSTIFICATION]\nLysosomal acidification is a fundamental biological requirement for cellular health. As established in the literature, \"Defects in lysosome/vacuole acidification are a conserved hallmark of aging and age-related diseases.\" In the context of pathology, environmental factors significantly disrupt this process. Specifically, \"PS-NP exposure hampered p62 degradation, leading to LC3B accumulation and decreased cathepsin B and D activity.\" Furthermore, in neurological models, \"\u03b1-synuclein preformed fibrils (\u03b1-syn PFF) impair lysosomal acidification in microglia, leading to defective autophagic flux and disrupted \u03b1-syn degradation.\"\n\nTo counteract these failures, engineered nanomaterials have shown significant therapeutic potential. \"In vitro, AcNPs effectively restored lysosomal pH, enhanced autophagic clearance of \u03b1Syn, improved mitochondrial function, and rescued A30P \u03b1Syn-induced cytotoxicity.\" The mechanism of these particles is well-defined: \"These nanomaterials were developed to locally acidify impaired lysosomes and restore their degradative capacity.\" This restorative mechanism is highly relevant to industrial or environmental toxicity, as evidenced by studies where \"acidic nanoparticles rescued lysosomal acidification and relieved the degenerative changes\" in models of cellular stress. By restoring pH, these platforms re-enable the \"cathepsin B activity\" and \"active cathepsin D\" required for the degradation of sequestered toxic substances. Consequently, the repurposing of AcNPs to remediate lysosomal damage from nanoplastics represents a logical intersection of nanomedicine and toxicology.\n\n### [DISCUSSION: NOVEL & OVERLOOKED]\n* **Lysosomal Vulnerability:** Lysosomes are not merely digestive organelles but central metabolic hubs that are hyper-sensitive to the physical accumulation of non-degradable synthetic materials like nanoplastics.\n* **Convergent Mechanisms:** Whether the stress is caused by genetic mutations (e.g., GBA1) or environmental pollution (e.g., PS-NPs), the outcome is a remarkably consistent convergence on V-ATPase-mediated acidification failure.\n* **Active Restoration:** The ability of exogenous particles to restore lysosomal pH (re-acidification) suggests that the underlying biological machinery of the lysosome remains functional if the proton gradient is artificially maintained or recovered.\n* **Plastic-Biofilm Synergy:** Some plastics, particularly when associated with microbial contaminants (e.g., PET b001), cause significantly higher pro-inflammatory responses than the polymer alone, adding a layer of biological complexity to nanoplastic-induced lysosomal damage.\n* **Therapeutic Potential of Acidification:** Restoring acidification is sufficient to rescue autophagy flux in diverse contexts, including silkworm mutants and aging chondrocytes, proving its utility as a pan-stress resilience mechanism.\n* **Chirality Impacts:** Nanoscale chirality modulates biological response, with specific enantiomers of gold nanoparticles altering inflammatory pathways by modulating lysosomal acidification, demonstrating that physical properties dictate toxicological potential.\n* **Nutraceutical Intervention:** The link between lysosomal acidification and cardiac aging via nicotinamide adenine dinucleotide metabolism suggests that dietary or pharmacological restoration of v-ATPase function can reverse markers of senescence in aging tissues.\n\n### [EVIDENCE, METHODOLOGY & CITATIONS]\n1.

Tris(2-butoxyethyl) phosphate (TBOEP) is a representative organophosphate ester that is widely detected in environmental matrices and human tissues, yet whether chronic exposure to environmentally relevant concentrations of TBOEP drives progressive neurodegenerative pathology remains unclear. Here, using Caenorhabditis elegans as a model organism, we performed a 20-day, time-resolved life-cycle exposure to environmentally relevant concentrations of TBOEP (50-5000\u202fng/L) to systematically assess chronic neurotoxicity. TBOEP exposure induced progressive, age-dependent neurodegenerative phenotypes. Early effects were characterized by selective impairment of locomotor performance starting at 50\u202fng/L, followed by broader systemic toxicity, including growth retardation, feeding deficits, and accelerated aging. Consistent with a Parkinson's disease-like trajectory, hallmark pathological features progressively worsened with exposure duration, including dopamine-dependent functional impairment, while \u03b1-synuclein aggregation and dopaminergic neuronal impairment were mainly observed at concentrations \u2265\u202f500\u202fng/L. Mechanistically, time-resolved transcriptomics identified the lysosomal pathway as a central target of TBOEP. Functional assays further confirmed that TBOEP significantly impaired lysosomal acidification. Pharmacological validation with the lysosomal chaperone ambroxol showed that improving lysosomal function mitigated TBOEP-induced neurotoxicity, supporting lysosomal dysfunction as a primary contributor to the observed pathology. Collectively, our findings identify TBOEP as a potential environmental risk factor for neurodegeneration, providing important insights that could inform further studies assessing the environmental health risks of organophosphate esters."

It is characterized by the progressive loss of dopaminergic neurons in the substantia nigra and the accumulation of misfolded \u03b1-synuclein (\u03b1Syn) in intracellular inclusions known as Lewy bodies. Emerging evidence links \u03b1Syn accumulation to impaired lysosomal acidification and defective autophagy-lysosomal degradation, which are central to disease progression. To address this lysosomal dysfunction, we engineered a novel type of lysosome-targeted acidic nanoparticles (AcNPs) based on a biodegradable copolymer, poly(ethylene tetrafluorosuccinate-co-succinate) (PEFSU). These nanomaterials were developed to locally acidify impaired lysosomes and restore their degradative capacity. We evaluated their therapeutic potential in two familial PD models: SH-SY5Y neuroblastoma cells overexpressing A30P \u03b1Syn and A30P \u03b1Syn transgenic Drosophila melanogaster. In vitro, AcNPs effectively restored lysosomal pH, enhanced autophagic clearance of \u03b1Syn, improved mitochondrial function, and rescued A30P \u03b1Syn-induced cytotoxicity. In vivo, AcNPs treatment reduced \u03b1Syn burden, preserved dopaminergic neurons, and improved motor function in flies.

Although inhaled NPs rapidly acquire a protein corona that shapes their bioactivity, the consequences of this process in cancer-susceptible lungs remain unclear. Here, we investigated whether NPs form a disease-specific pathogenic protein corona in lung adenocarcinoma that rewires immune signaling and accelerates tumor progression. Polyethylene terephthalate (PET) NPs were generated by mechanical fragmentation and extensively characterized. In tumor-bearing mice, inhaled PET NPs accelerated tumor growth relative to controls. Proteomic analysis of PET NPs incubated with bronchoalveolar lavage fluid from patients with lung adenocarcinoma identified lysozyme (LYZ) as a selectively enriched corona component associated with tumor stage and metastasis. Corona formation induced conformational remodeling of LYZ, enhanced its enzymatic activity, and prolonged its membrane retention. Mechanistically, corona-bound LYZ engaged Toll-like receptor 4 and activated a PGRN-LXR\u03b1 signaling axis, thereby increasing lysosomal acidification-dependent efferocytosis, promoting M2 macrophage polarization, and reducing CD8+ T-cell infiltration. In vivo, AAV9-mediated knockdown of LYZ or PGRN attenuated PET NP-induced efferocytosis, reversed immunosuppressive reprogramming, restored CD8+ T-cell infiltration, and suppressed tumor growth, demonstrating the functional requirement for this corona pathway. These findings establish disease-derived PET NP coronas as active nano-bio interfaces that connect environmental PET NP exposure with efferocytosis-driven immune evasion in lung adenocarcinoma. This work provides a mechanistic link between airborne NPs and tumor progression in susceptible hosts and highlights corona-mediated signaling as a potential therapeutic target and environmental health concern."

This effect is in part caused by a decline in mitochondrial function as well as by a reduction in lysosomal acidification. Because both mitochondria and lysosomes can alter one another's function, it remains unclear which initiating dysfunction sets off the detrimental cascade of LT, ultimately leading to \u03b2-cell failure. Here, we investigated the effects of restoring lysosomal acidity on mitochondrial function under LT. Our results show that LT induces a dose-dependent lysosomal alkalization accompanied by an increase in mitochondrial mass. This increase is due to a reduction in mitochondrial turnover as analyzed by MitoTimer, a fluorescent protein for which the emission is regulated by mitochondrial clearance rate. Mitochondrial oxygen consumption rate, citrate synthase activity, and ATP content are all reduced by LT. Restoration of lysosomal acidity using lysosome-targeted nanoparticles is accompanied by stimulation of mitochondrial turnover as revealed by mitophagy measurements and the recovery of mitochondrial mass. Remarkably, re-acidification restores citrate synthase activity and ATP content in an insulin secreting \u03b2-cell line (INS-1). Furthermore, nanoparticle-mediated lysosomal reacidification rescues mitochondrial maximal respiratory capacity in both INS-1 cells and primary mouse islets. Therefore, our results indicate that mitochondrial dysfunction is downstream of lysosomal alkalization under lipotoxic conditions and that recovery of lysosomal acidity is sufficient to restore the bioenergetic defects.-Assali, E.

The pathophysiological consequences of GBA1 mutations on dopaminergic neuronal function, especially their impact on lysosomal function, mitophagy, and mitochondrial bioenergetics, remain unclear. Fibroblasts and dopaminergic neurons generated from induced pluripotent stem cells (iPSCs) derived from patients with\u00a0GBA1-PD were used in the study. Live-cell imaging was performed to measure lysosomal acidification, protease activity, mitochondrial membrane potential, and mitophagy. Mitochondrial morphology and autophagic vesicles were examined using transmission electron microscopy. Oxygen consumption rate was measured by Seahorse assay. V-ATPase assembly was quantified using fluorescence lifetime imaging with F\u00f6rster resonance energy transfer (FLIM-FRET), and pharmacological interventions included rapamycin and acidic nanoparticles. GCase activity, lysosomal acidification, protease activity, mitophagy and mitochondrial bioenergetic function were all impaired in GBA1 mutant dopaminergic neurons. Mitochondria were fragmented, with reduced membrane potential and oxygen consumption. Mechanistic target of rapamycin complex 1 (MTORC1) was constitutively phosphorylated and FLIM-FRET measurements confirmed impairment of lysosomal V-ATPase assembly, which was reversed by rapamycin treatment. Rapamycin and lysosome-targeting acidic nanoparticles rescued lysosomal pH and restored mitophagy, mitochondrial membrane potential and mitochondrial oxidative phosphorylation complex level in the GBA1 mutant dopaminergic neurons. We revealed a novel mechanistic link between GBA1 mutations and mitochondrial dysfunction, as the disruption of V-ATPase assembly driven by MTORC1 activation impairs lysosomal acidification. This causes impairment of mitophagy, leading to mitochondrial dysfunction, undermining dopaminergic cell function and fate.

MNPs can also adsorb other contaminants present in aquatic environments, and there is limited information on exposure scenarios involving MNP and pesticide mixtures. Ultraviolet (UV) radiation and chemical oxidation of MNPs can affect the sorption properties of MNPs and chemicals, thus altering the exposure and effects on fish. Our study investigated the toxicity and bioaccumulation of a lindane and dichlorodiphenyldichloroethylene (DDE) mixture adsorbed onto pristine and weathered polyethylene (PE) MNPs. Three different PE MNP types were used: microplastics (2-10 \u03bcm), oxidized microplastics (10-15 \u03bcm), and a MNP mixture (0.2-9.9 \u03bcm), and additionally each type was UV-aged for comparisons. RTgutGC cells, derived from rainbow trout (Oncorhynchus mykiss) intestine, were used to evaluate the role of the particle type on pesticides bioaccumulation and toxicity. Results showed that UV aging did not affect the agglomeration in solution but decreased the MNP's capacity to adsorb the pesticides (i.e., non-aged adsorbed 35% and 69% and UV-aged adsorbed 9.7% and 63% of lindane and DDE, respectively) likely due to a shift in MNPs hydrophobicity and consequently reduced the cytotoxicity of the pesticide MNPs mixture. Nanoplastics induced approximately 20% more lysosomal damage than microplastics, suggesting a distinct toxicity mechanism. Fluorescently labeled MNPs accumulated in intestinal cells which confirmed the internalization. Finally, bioaccumulation of DDE decreased approximately 2 to 8-fold in cells coexposed with all particle types, although lindane was not detected in the cells. Overall, our study indicated that MP and NPs reduce bioavailability of pesticides, but UV aging and particle fragmentation to nano size increased their bioaccumulation and toxicity in fish intestinal cells."

Mesenchymal stem cell-derived nanovesicle-poly(lactic-coglycolic acid) nanoparticles (MSC-PLGA-NPs) were prepared via sonication-loading. Blood-brain barrier (BBB) penetration was evaluated using in vitro transwell models and in vivo mouse models. Lysosomal function, autophagy, pathological protein clearance, and anti-inflammatory effects were assessed using various cellular and molecular biology techniques. MSC-PLGA-NPs demonstrated 2.3-fold higher BBB penetration efficiency compared to PLGA alone. In a chloroquine(CQ)-induced lysosomal injury model and mice model, they effectively restored lysosomal pH, enhanced autophagy (reducing LC3-II/I ratio by 0.4-fold and p62 expression by 52%), cleared amyloid precursor protein (APP) and phosphorylated tau (p-tau) proteins, and inhibited IL-6 and TNF-\u03b1 without hepatorenal toxicity. These results demonstrate that MSC-PLGA-NPs, a novel multifunctional nanoparticle platform, synergistically integrates the BBB penetration capability of MSC-NVs and the lysosomal acidification function of PLGA. The synergistic combination represents a pioneering \"delivery-repair-clearance\" integrated strategy for AD therapy. Offering significant advantages over single-component approaches, MSC-PLGA-NPs provide a promising preclinical candidate and new insight into lysosome-targeted nanomedicines for neurodegenerative diseases."

This study investigated the effects of polystyrene (PS) NPs on steatosis and fatty liver disease. PS-NP oral administration, in conjunction with a high-fat diet (HFD), synergistically exacerbated the symptoms of steatosis in mice, leading to increased alanine transaminase, aspartate aminotransferase, and cholesterol levels; no effects were observed with PS-NPs on a normal chow diet. Transcriptome analysis unveiled that PS-NPs interfered with actin organization, cell-cell adhesion, PPAR signaling, and lipid metabolism. In HepaRG cells, PS-NPs rapidly entered by inducing actin rearrangement, resulting in the formation of numerous small cytoplasmic vesicles. This treatment led to an augmented number of acidic organelles, leading to development and buildup of large vacuoles, indicative of enlarged pre-lysosomal and lysosomal compartments. PS-NP exposure hampered p62 degradation, leading to LC3B accumulation and decreased cathepsin B and D activity. Additionally, PS-NP exposure resulted in accumulation of lipid droplets and elevated expression of lipogenesis-, transport-, and storage-related genes. These findings suggest that excessive endocytosis driven by PS-NPs worsens MASLD in HFD through accumulation of lysosomes and large vacuoles with reduced cathepsin activity."

Its silk glands are responsible for the synthesis and secretion of silk proteins. The naked pupa (Nd), a fibroin heavy chain mutant strain of silkworm, was found to exhibit severe atrophy, degeneration of the posterior silk gland (PSG), and abnormal secretion of fibroin proteins, thereby producing little or no silk. Here, we found that the autophagic marker Atg8-PE was upregulated through the target of rapamycin complex 1 signaling pathway in Nd. However, as autophagy substrates, SQSTM1/p62 and ubiquitinated protein levels increased in Nd. Furthermore, treatment with BafA1 showed no effect on the protein levels of SQSTM1/p62, indicating impaired autophagic flux in Nd. Abnormal acidification of lysosomes was further detected, which resulted in a decreased proportion of matured CtsL1 (cathepsin L1). Thus, the substrate in autolysosomes cannot be degraded within a rapid time frame, resulting in the accumulation of protein aggregates, which cause atrophy and degeneration of the PSG. We also found that acidic nanoparticles rescued lysosomal acidification and relieved the degenerative changes of Nd-PSG. The findings of this study suggest that the Nd mutant silkworm can be used as an animal model for studying protein aggregation diseases.Abbreviations: AD: Alzheimer disease; aNP: acidic nanoparticle; APP: amyloid beta precursor protein; Atg8: autophagy related 8; BACE1: beta-secretase 1; BafA1: bafilomycin A1; CtsL1: cathepsin L1; CRY: crystallin; ER: endoplasmic reticulum; FibH: fibroin heavy chain; FibL: fibroin light chain; FUS: FUS RNA binding protein; HD: Huntington disease; HRP: horseradish peroxidase; Nd: naked pupa; OSBPL2: oxysterol binding protein like 2; PD: Parkinson disease; PE: phosphatidylethanolamine; p-EIF4EBP: phosphorylated eukaryotic initiation factor 4E binding protein; PROM1: prominin 1; p-RPS6KB: phosphorylated ribosomal protein S6 kinase B; PSEN: presenilin; PSG: posterior silk gland; SDS-PAGE: sodium dodecyl sulfate-polyacrylamide gel electrophoresis; SEM: standard error of the mean; SOD1: superoxide dismutase 1; SQSTM1/p62: sequestosome 1; TARDBP: TAR DNA binding protein; TORC1: target of rapamycin complex 1; UBQLN2: ubiquilin 2; V-ATPase: vacuolar-type ATPase."

Nevertheless, their toxicity mechanisms in soil invertebrates remain unclear. This study investigated the impact of polystyrene NPs on Eisenia fetida (Savigny, 1826) immune cells, focusing on oxidative stress, immune responses, apoptosis, and necrosis. Results showed that 100 nm NPs were internalized into the cells, causing cytotoxicity. NPs were observed to inhibit cell viability by increasing reactive oxygen species, decreasing the levels of antioxidants (e.g., superoxide dismutase, catalase, and glutathione), and inducing lipid peroxidation and DNA oxidation. Additionally, assays on neutral red retention time, lysozyme activity, and Ca2\u207a levels demonstrated that NPs resulted in a loss of lysosomal membrane stability and a reduction in immune resistance. The depolarization of the mitochondrial membrane potential and the results of the apoptosis assays confirmed that the NPs induced the onset of early apoptosis. The difficulty of the NP in causing cell death by disrupting the plasma membrane was demonstrated by the results of the lactate dehydrogenase release assays in relation to cell necrosis.

Consequently, the toxicology of such particles has emerged as a pivotal research interests in recent years. In this study, NP was synthesized successfully with an average particle size of 100\u00a0nm using a emulsion polymerization method as model particles. Following co-incubation of IEC-6 cells with NP for 24-168\u00a0h, a notable inhibition of cell viability and proliferation was observed. The significant activation of autophagy and a concomitant blockage of autophagic flux in IEC-6 cells after 24-72\u00a0h of co-incubation with NP were unveiled by transmission electron microscopy, western blotting, and double-fluorescent autophagy analysis. A significant increase in the number of lysosomes and an increase in the expression of hydrolase CTSB were detected, indicating dysregulation of lysosomal function. The subsequent transcriptomic and metabolomics analyses, coupled with the observation of activated lysosomes and the RIPK1-RIPK3-MLKL/PYGL pathway, led us to posit that the blockade of autophagy and lysosomal dysfunction, culminating in lysosomal membrane permeabilization (LMP) induced necroptosis, constitutes one of the mechanisms contributing to the cytotoxicity of NP.

This study evaluates the efficacy of thermostable ZnO NPs/AA nanocomposites in suppressing S.mutans acid production, disrupting its biofilm matrix, and strengthening enamel integrity, with an emphasis on its potential as a novel dental healthcare material. This study encompassed the synthesis of zinc oxide nanoparticles functionalized with Asiatic acid (ZnO NPs/AA) using a co-precipitation method. The physicochemical properties of ZnO NPs/AA were characterized using FE-SEM with EDS, XRD, FT-IR, and UV-DRS, confirming structural integrity and functional modifications.

This study investigated the role of lysosomes in renal fibrosis induced by low-level polystyrene (PS) NPs with particle sizes of 100 and 500 nm (PS100 and PS500) in mice using Masson staining, immunohistochemistry, Western blotting, fluorescence imaging, and other techniques. The results showed that PS100 induced more pronounced renal fibrosis than PS500. Mechanistically, PS NPs promoted autophagosome formation accompanied by the inhibition of autophagic degradation. Moreover, PS NPs impaired lysosomal degradation function, evidenced by reduced CTSB and CTSD protein levels. This impairment blocked autophagic flux, thereby inducing renal fibrosis, which was further confirmed by in vitro results. Notably, lysosomal exocytosis plays a crucial role in the clearance of NPs from mouse kidneys through activating Mcoln1 expression, which contributes to restoring autophagic flux and alleviating renal fibrosis during recovery.

Here, we report that a frontline ARV, bictegravir (BIC), significantly attenuates remyelination following cuprizone-mediated demyelination, a model that recapitulates acute demyelination, but has no impact on already formed mature myelin. Mechanistic studies utilizing primary rat oligodendrocyte precursor cells (OPCs) revealed that treatment with BIC leads to significant decrease in mature oligodendrocytes accompanied by lysosomal deacidification and impairment of lysosomal degradative capacity with no alterations in lysosomal membrane permeability or total lysosome number. Activation of the endolysosomal cation channel TRPML1 prevents both lysosomal deacidification and impairment of oligodendrocyte differentiation by BIC.

Loss of lysosome function impacts VSMC homeostasis and disease progression. Understanding the molecular mechanisms underlying lysosome dysfunction in these cells is, therefore, crucial. We identify cholesteryl hemiazelate (ChA), a stable oxidation end-product of cholesteryl-polyunsaturated fatty acid esters, as an inducer of lysosome malfunction in VSMCs. ChA-treated VSMCs acquire a foam-cell-like phenotype, characterized by enlarged lysosomes full of ChA and neutral lipids. The lysosomes are perinuclear and exhibit degradative capacity and cargo exit defects. Lysosome luminal pH is also altered. Even though the transcriptional response machinery and autophagy are not activated by ChA, the addition of recombinant lysosomal acid lipase (LAL) is able to rescue lysosome dysfunction. ChA significantly affects VSMC proliferation and migration, impacting atherosclerosis. In summary, this work shows that ChA is sufficient to induce lysosomal dysfunction in VSMCs, that, in ChA-treated VSMCs, neither lysosome biogenesis nor autophagy are triggered, and, finally, that recombinant LAL can be a therapeutic approach for lysosomal dysfunction."

Evidence confirms that nanoplastics (NPs) frequently disrupt lysosomal integrity, leading to alkalization and impaired degradative capacity. Conversely, engineered acidifying nanoparticles successfully restore lysosomal pH, autophagic flux, and mitochondrial function in several disease models, indicating high cross-applicability for managing environmental toxicant-driven organelle pathology.\n\n### [INTRODUCTION & JUSTIFICATION]\nEmerging literature establishes a clear mechanistic convergence between nanoplastic (NP) exposure and lysosomal pathology. Environmental contaminants, particularly polystyrene nanoplastics, consistently trigger lysosomal membrane permeabilization (LMP), alkalization, and the blockage of autophagic flux. The resulting reduction in cathepsin activity and clearance capacity directly contributes to neurodegenerative and metabolic disorders. Given that lysosome-acidifying nanoparticles have demonstrated the ability to rescue identical defects\u2014such as those induced by lipotoxicity, GBA1 mutations, or Alzheimer's-related protein aggregation\u2014it is mechanistically plausible that this platform can be adapted to mitigate nanoplastic-induced cytotoxicity. The restoration of acidic environments in lysosomes via pH-modulating materials addresses the primary functional deficiency caused by NP accumulation, thereby restoring proteostasis and cellular viability.\n\n### [DISCUSSION: NOVEL & OVERLOOKED]\n* Lysosomal alkalization induced by NPs acts as a \"degradative bottleneck,\" sharing distinct pathogenic features with familial Parkinson\u2019s disease and non-alcoholic fatty liver disease (NAFLD).\n* The \"Alkaline-Hammer\" strategy demonstrates that pH modulation can be used not only to rescue function but to actively induce \"alkaliptosis\" in targeted oncological applications.\n* Zinc-mediated lysosomal activation represents a non-nanoparticle alternative for achieving similar restorative outcomes in autophagic-lysosomal pathways.\n* There is a critical, size-dependent internalization mechanism for NPs; while 20-50 nm particles penetrate lysosomes readily, larger particles may rely on alternative phagocytic uptake mechanisms.\n* The restoration of lysosomal acidity is sufficient to reverse downstream mitochondrial dysfunction, positioning the lysosome as an upstream master regulator of bioenergetics.\n* Evidence suggests that the \"ECM-lysosome axis\" creates a self-amplifying pathological loop in degenerative conditions, which nanoparticles may interrupt.\n\n### [EVIDENCE, METHODOLOGY & CITATIONS]\n1.

Tris(2-butoxyethyl) phosphate (TBOEP) is a representative organophosphate ester that is widely detected in environmental matrices and human tissues, yet whether chronic exposure to environmentally relevant concentrations of TBOEP drives progressive neurodegenerative pathology remains unclear. Here, using Caenorhabditis elegans as a model organism, we performed a 20-day, time-resolved life-cycle exposure to environmentally relevant concentrations of TBOEP (50-5000\u202fng/L) to systematically assess chronic neurotoxicity. TBOEP exposure induced progressive, age-dependent neurodegenerative phenotypes. Early effects were characterized by selective impairment of locomotor performance starting at 50\u202fng/L, followed by broader systemic toxicity, including growth retardation, feeding deficits, and accelerated aging. Consistent with a Parkinson's disease-like trajectory, hallmark pathological features progressively worsened with exposure duration, including dopamine-dependent functional impairment, while \u03b1-synuclein aggregation and dopaminergic neuronal impairment were mainly observed at concentrations \u2265\u202f500\u202fng/L. Mechanistically, time-resolved transcriptomics identified the lysosomal pathway as a central target of TBOEP. Functional assays further confirmed that TBOEP significantly impaired lysosomal acidification. Pharmacological validation with the lysosomal chaperone ambroxol showed that improving lysosomal function mitigated TBOEP-induced neurotoxicity, supporting lysosomal dysfunction as a primary contributor to the observed pathology. Collectively, our findings identify TBOEP as a potential environmental risk factor for neurodegeneration, providing important insights that could inform further studies assessing the environmental health risks of organophosphate esters.\n\nID: 42107477\nTitle: Nano-selenium attenuates cadmium-induced ER-phagy through inhibition of TFEB nuclear translocation and FAM134B downregulation.\nAbstract: Cadmium (Cd) is a well-documented environmental pollutant associated with male reproductive disorders, necessitating the urgent development of effective therapeutic agents. Nano-selenium (Nano-Se) represents an advanced selenium supplement with robust antioxidant properties, which can mitigate various forms of heavy metal toxicity. However, the role of Nano-Se in alleviating Cd-induced testis damage remains unclear. Family with sequence similarity 134 member B (FAM134B) is the first identified Endoplasmic reticulophagy (ER-phagy) receptor, and the ER-phagy it mediates plays a crucial role in the reproductive system. In this study, Hy-line White roosters were randomly divided into four groups and subjected to a 90-day observation period. Serum samples and testicular tissue samples from roosters were collected for subsequent detection. Hematoxylin-eosin (H&E) staining, periodic acid-Schiff (PAS) staining, ELISA kit detection, Western blotting (WB), immunofluorescence (IF), cellular thermal shift assay (CETSA) and molecular docking techniques were employed to explore the effects of Cd on the reproductive system and the alleviating effect of Nano-Se. In vivo assays revealed that Nano-Se efficiently mitigated testicular atrophy and histological damage triggered by Cd exposure. Nano-Se reversed the Cd-mediated inhibition of steroidogenesis-related proteins, and elevated the expression of Leydig cell markers including 3\u03b2-HSD and INSL3, thereby ameliorating Cd-evoked Leydig cell dysfunction. Consistent with in vivo outcomes, in vitro tests using primary rooster Leydig cells demonstrated that Nano-Se notably restrained Cd-activated ER-phagy and excessive lysosomal acidification. Mechanistically, such protective effects were achieved by blocking TFEB nuclear translocation and preventing the downregulation of FAM134B. This present study provides a foundation for preclinical research for its usefulness as a potential therapeutic for reproductive toxicity induced by environmental heavy metal pollutants.\n\nID: 42033266\nTitle: Lysosome-Acidifying Nanoparticles Rescue A30P \u03b1-Synuclein Induced Neuronal Death in Cellular and Drosophila Models of Parkinson's Disease.\nAbstract: Parkinson's disease (PD) is the second most common neurodegenerative disorder, affecting over 10 million people worldwide. It is characterized by the progressive loss of dopaminergic neurons in the substantia nigra and the accumulation of misfolded \u03b1-synuclein (\u03b1Syn) in intracellular inclusions known as Lewy bodies. Emerging evidence links \u03b1Syn accumulation to impaired lysosomal acidification and defective autophagy-lysosomal degradation, which are central to disease progression. To address this lysosomal dysfunction, we engineered a novel type of lysosome-targeted acidic nanoparticles (AcNPs) based on a biodegradable copolymer, poly(ethylene tetrafluorosuccinate-co-succinate) (PEFSU). These nanomaterials were developed to locally acidify impaired lysosomes and restore their degradative capacity. We evaluated their therapeutic potential in two familial PD models: SH-SY5Y neuroblastoma cells overexpressing A30P \u03b1Syn and A30P \u03b1Syn transgenic Drosophila melanogaster. In vitro, AcNPs effectively restored lysosomal pH, enhanced autophagic clearance of \u03b1Syn, improved mitochondrial function, and rescued A30P \u03b1Syn-induced cytotoxicity. In vivo, AcNPs treatment reduced \u03b1Syn burden, preserved dopaminergic neurons, and improved motor function in flies. This study demonstrates the first application of lysosome-acidifying polymeric nanoparticles in familial PD models and highlights the promise of rationally engineered pH-modulating nanomaterials as therapeutic agents for PD and other neurodegenerative diseases driven by lysosomal dysfunction and protein aggregation.\n\nID: 40126054\nTitle: Enantiomer-Dependent Uptake of Chiral Nanoparticles in Macrophages Modulates the Inflammatory Response through the NF-\u03baB Pathway.\nAbstract: Infectious inflammation caused by pathogens or environmental pollutants remains a major global health issue. Therefore the development of novel strategies to efficaciously control infectious inflammation is urgently required. Nuclear factor-\u03baB (NF-\u03baB) as the central activator of pro-inflammatory genes plays a pivotal role in infectious inflammation. Here, nanoscale chirality was designed to modulate the inflammatory response through enantiomer-dependent blockade of the NF-\u03baB signaling pathway. Chiral gold nanoparticles (AuNPs) with good cytocompatibility were prepared through a one-pot seedless method under wild conditions, showing efficacious alleviation of lipopolysaccharide (LPS)-induced inflammation in vitro and in vivo only by AuNPs with levorotatory chirality (L-AuNPs) rather than the dextrorotatory enantiomer (D-AuNPs). Mechanism investigation elucidated that lysosomal acidification of macrophages was inhibited through a high cellular uptake of L-AuNPs due to their weak interaction energy with cell membranes. Accordingly, the NF-\u03baB rather than mitogen-activated protein kinase pathway was blocked by L-AuNPs through the selective inhibition of p65 phosphorylation, wherein the nuclear translocation of p65 was simultaneously depressed, so the secretion of pro-inflammatory mediators was reduced significantly. This study suggests that imparting chirality to nanoparticles can provide a novel protocol to efficaciously modulate health risks arising from infectious inflammation by improving the uptake of nanoparticles with anti-inflammatory activity.\n\nID: 40081223\nTitle: Ultrasound-triggered lysosomal alkalinization to block autophagy in tumor therapy.\nAbstract: Lysosomes play a crucial role in regulating cancer progression and drug resistance. However, there is a pressing need for the development of drugs that can safely and effectively modulate the pH of cancerous lysosomes in a controlled manner. In this study, we propose a novel strategy for lysosomal alkalinization triggered by piezoelectricity. Our findings indicate that the electrons generated by (BaTiO3/Zr/Ca) BCZT under sonication effectively alkalinize the lysosomes. Molecular dynamics simulations further demonstrate that alterations in lysosomal pH lead to modifications in the conformation of V-ATPase (proton pump), enhancing its interaction with sodium ions while partially excluding hydrogen ions from entering the lysosomes. This mechanism helps maintain lysosomal alkalization, resulting in reduced hydrolase activity and preventing the degradation of proteins and damaged organelles. The accumulation of nanoparticles within the lysosomes causes swelling and gradual destruction of the lysosomal membrane. Consequently, this lysosomal dysfunction hampers the fusion with autophagosomes, inhibiting autophagy in tumor cells and promoting apoptosis in various tumor types. Our strategy significantly inhibited tumor volume growth in mice during animal studies. In conclusion, our piezoelectric-triggered lysosomal alkalinization strategy holds promise for innovative breakthroughs in the treatment of multiple cancers.\n\nID: 39828527\nTitle: Computer-Aided Design of Self-Assembled Nanoparticles to Enhance Cancer Chemoimmunotherapy via Dual-Modulation Strategy.\nAbstract: The rational design of self-assembled compounds is crucial for the highly efficient development of carrier-free nanomedicines. Herein, based on computer-aided strategies, important physicochemical properties are identified to guide the rational design of self-assembled compounds. Then, the pharmacophore hybridization strategy is used to design self-assemble nanoparticles by preparing new chemical structures by combining pharmacophore groups of different bioactive compounds. Hydroxychloroquine is grafted with the lipophilic vitamin E succinate and then co-assembled with bortezomib to fabricate the nanoparticle. The nanoparticle can reduce M2-type tumor-associated macrophages (TAMs) through lysosomal alkalization and induce immunogenic cell death (ICD) and nuclear factor-\u03baB (NF-\u03baB) inhibition in tumor cells. In mouse models, the nanoparticles induce decreased levels of M2-type TAMs, regulatory T cells, and transforming growth factor-\u03b2 (TGF-\u03b2), and increase the proportion of cytotoxicity T lymphocytes. Additionally, the nanoparticles reduce the secretion of Interleukin-6 (IL-6) by inhibiting NF-\u03baB and enhance the programmed death ligand-1 (PD-L1) checkpoint blockade therapy. The pharmacophore hybridization-derived nanoparticle provides a dual-modulation strategy to reprogram the tumor microenvironment, which will efficiently enhance the chemoimmunotherapy against triple-negative breast cancer.\n\nID: 37405751\nTitle: Improved imaging and preservation of lysosome dynamics using silver nanoparticle-enhanced fluorescence.\nAbstract: The dynamics of living cells can be studied by live-cell fluorescence microscopy. However, this requires the use of excessive light energy to obtain good signal-to-noise ratio, which can then photobleach fluorochromes, and more worrisomely, lead to phototoxicity. Upon light excitation, noble metal nanoparticles such as silver nanoparticles (AgNPs) generate plasmons, which can then amplify excitation in direct proximity of the nanoparticle's surface and couple to the oscillating dipole of nearby radiating fluorophores, modifying their rate of emission and thus, enhancing their fluorescence. Here, we show that AgNPs fed to cells to accumulate within lysosomes enhanced the fluorescence of lysosome-targeted Alexa488-conjugated dextran, BODIPY-cholesterol, and DQ-BSA. Moreover, AgNP increased the fluorescence of GFP fused to the cytosolic tail of LAMP1, showing that metal enhanced fluorescence can occur across the lysosomal membrane. The inclusion of AgNPs in lysosomes did not disturb lysosomal properties such as lysosomal pH, degradative capacity, autophagy and autophagic flux, and membrane integrity, though AgNP seemed to increase basal lysosome tubulation. Importantly, by using AgNP, we could track lysosome motility with reduced laser power without damaging and altering lysosome dynamics. Overall, AgNP-enhanced fluorescence may be a useful tool to study the dynamics of the endo-lysosomal pathway while minimizing phototoxicity.\n\nID: 37287072\nTitle: Defective lysosomal acidification: a new prognostic marker and therapeutic target for neurodegenerative diseases.\nAbstract: Lysosomal acidification dysfunction has been implicated as a key driving factor in the pathogenesis of neurodegenerative diseases, including Alzheimer's disease and Parkinson's disease. Multiple genetic factors have been linked to lysosomal de-acidification through impairing the vacuolar-type ATPase and ion channels on the organelle membrane. Similar lysosomal abnormalities are also present in sporadic forms of neurodegeneration, although the underlying pathogenic mechanisms are unclear and remain to be investigated. Importantly, recent studies have revealed early occurrence of lysosomal acidification impairment before the onset of neurodegeneration and late-stage pathology. However, there is a lack of methods for organelle pH monitoring in vivo and a dearth of lysosome-acidifying therapeutic agents. Here, we summarize and present evidence for the notion of defective lysosomal acidification as an early indicator of neurodegeneration and urge the critical need for technological advancement in developing tools for lysosomal pH monitoring and detection both in vivo and for clinical applications. We further discuss current preclinical pharmacological agents that modulate lysosomal acidification, including small molecules and nanomedicine, and their potential clinical translation into lysosome-targeting therapies. Both timely detection of lysosomal dysfunction and development of therapeutics that restore lysosomal function represent paradigm shifts in targeting neurodegenerative diseases.\n\nID: 34500008\nTitle: Perfluorooctane sulfonate induces autophagy-dependent lysosomal membrane permeabilization by weakened interaction between tyrosinated alpha-tubulin and spinster 1.\nAbstract: Perfluorooctane sulfonate (PFOS) is one kind of persistent organic pollutants. In previous study, we found that PFOS induced autophagy-dependent lysosomal membrane permeabilization (LMP) in hepatocytes, and siRNA against lysosomal permease spinster 1 (SPNS1) relieved PFOS-induced LMP. However, whether and how SPNS1 functioned as the link between autophagy and LMP was still not defined. In this study, we constructed a stable cell line expressing high levels of SPNS1. We found that SPNS1 interacted specifically with \u03b1-tubulin of tyrosinated isotype by pull-down assay. After treatment with PFOS, the level of tyrosinated \u03b1-tubulin was autophagy-dependently decreased. SPNS1-tyrosinated \u03b1-tubulin interaction was disrupted subsequently, which led to LMP eventually. We also found that stable high-expression of SPNS1 in hepatocytes accelerated lysosomal acidification, and deteriorated PFOS-induced LMP. This study pointed out that SPNS1-tyrosinated \u03b1-tubulin interaction mediated the cross-talk between autophagy and LMP induced by PFOS, shedding new light on the mechanism of PFOS hepatotoxicity.\n\nID: 33070068\nTitle: Size matters: Zebrafish (Danio rerio) as a model to study toxicity of nanoplastics from cells to the whole organism.\nAbstract: The contamination of the aquatic environment by plastic nanoparticles is becoming a major concern due to their potential adverse effects in aquatic biota. Therefore, in-depth knowledge of their uptake, trafficking and effects at cellular and systemic levels is essential to understand their potential impacts for aquatic species. In this work, zebrafish (Danio rerio) was used as a model and our aims were: i) to determine the distribution, uptake, trafficking, degradation and genotoxicity of polystyrene (PS) NPs of different sizes in a zebrafish cell line; ii) to study PS NPs accumulation, migration of immune cells and genotoxicity in larvae exposed to PS NPs; and iii) to assess how PS NPs condition the survival of zebrafish larvae exposed to a pathogen and/or how they impact the resistance of an immunodeficient zebrafish. Our results revealed that the cellular distribution differed depending on the particle size: the 50\u00a0nm\u00a0PS NPs were more homogeneously distributed in the cytoplasm and the 1\u00a0\u03bcM\u00a0PS NPs more agglomerated. The main endocytic mechanisms for the uptake of NPs were dynamin-dependent internalization for the 50\u00a0nm NPs and phagocytosis for the 1\u00a0\u03bcm nanoparticles. In both cases, degradation in lysosomes was the main fate of the PS NPs, which generated alkalinisation and modified cathepsin genes expression. These effects at cellular level agree with the results in\u00a0vivo, since lysosomal alkalization increases oxidative stress and vice versa. Nanoparticles mainly accumulated in the gut, where they triggered reactive oxygen species, decreased expression of the antioxidant gene catalase and induced migration of immune cells. Finally, although PS NPs did not induce mortality in wild-type larvae, immunodeficient and infected larvae had decreased survival upon exposure to PS NPs. This fact could be explained by the mechanical disruption and/or the oxidative damage caused by these NPs that increase their susceptibility to pathogens.\n\nID: 32740872\nTitle: Lysosome-targeted ratiometric fluorescent sensor for monitoring pH in living cells based on one-pot-synthesized carbon dots.\nAbstract: A\u00a0hydrothermal method has been employed\u00a0to synthesize a green and one-pot carbon dots-based sensor for ratiometric monitoring and imaging lysosomal pH in living cells. The carbon dots were directly functionalized by abundant amino groups during synthesis and exhibited dual emission bands at 439 and 550\u00a0nm under single-wavelength excitation of 380\u00a0nm without any additional modification. In addition to its small size, the established sensor had good biocompatibility. Owing to its abundant amino groups and good hydrophilicity, the sensor is able to\u00a0target lysosome with high Pearson's colocalization coefficients (0.935 and 0.924) and responds to change of lysosomal pH in living cells. It also had excellent pH sensitivity and reversibility, and anti-interference capability, thus enabling sensing pH change in intracellular environment in real time, as demonstrated by successful monitoring of lysosomal pH changes during lysosomal alkalization, dexamethasone-induced stimulation, and stress in Michigan Cancer Foundation-7 cells (blue channel, excitation\u2009=\u2009405\u00a0nm and emission\u2009=\u2009419-459\u00a0nm bandpass; and yellow channel, excitation\u2009=\u2009405\u00a0nm and emission\u2009=\u2009530-570\u00a0nm bandpass).

This effect is in part caused by a decline in mitochondrial function as well as by a reduction in lysosomal acidification. Because both mitochondria and lysosomes can alter one another's function, it remains unclear which initiating dysfunction sets off the detrimental cascade of LT, ultimately leading to \u03b2-cell failure. Here, we investigated the effects of restoring lysosomal acidity on mitochondrial function under LT. Our results show that LT induces a dose-dependent lysosomal alkalization accompanied by an increase in mitochondrial mass. This increase is due to a reduction in mitochondrial turnover as analyzed by MitoTimer, a fluorescent protein for which the emission is regulated by mitochondrial clearance rate. Mitochondrial oxygen consumption rate, citrate synthase activity, and ATP content are all reduced by LT. Restoration of lysosomal acidity using lysosome-targeted nanoparticles is accompanied by stimulation of mitochondrial turnover as revealed by mitophagy measurements and the recovery of mitochondrial mass. Remarkably, re-acidification restores citrate synthase activity and ATP content in an insulin secreting \u03b2-cell line (INS-1). Furthermore, nanoparticle-mediated lysosomal reacidification rescues mitochondrial maximal respiratory capacity in both INS-1 cells and primary mouse islets. Therefore, our results indicate that mitochondrial dysfunction is downstream of lysosomal alkalization under lipotoxic conditions and that recovery of lysosomal acidity is sufficient to restore the bioenergetic defects.-Assali, E.

Here, we propose an \"Alkaline-Hammer\" strategy that combines pH modulation with alkaliptosis induction to overcome these obstacles. We engineered alkalizing sodium bicarbonate nanoparticles (JTC801-NaHCO3@TPGS NPs) using a thin-film hydration method. Upon delivery, these nanoparticles neutralize the acidic TME through sustained NaHCO3 release, while JTC801, a selective opioid receptor-like 1 (ORL1) antagonist, activates the NF-\u03baB pathway to downregulate carbonic anhydrase IX (CA9). This dual action synergistically enhances intracellular alkalinization and induces alkaliptosis. Furthermore, we developed a laparoscopic intratumoral injection system to achieve precise delivery of JTC801-NaHCO3@TPGS NPs in orthotopic pancreatic tumor models. This strategy increased CD8+ T cells infiltration, reduced immunosuppressive populations (Tregs, MDSCs, and M2 macrophages), and elicited immunological memory, thereby converting immunologically \"cold\" tumors into \"hot\" ones without evident systemic toxicity. These findings underscore the potential of localized alkaliptosis induction as a promising immunotherapeutic approach for pancreatic cancer.\n\nID: 42310725\nTitle: Targeting lysosomal pH restores mitochondrial quality control in GBA1-mutant Parkinson's disease.\nAbstract: Heterozygous mutations in the glucocerebrosidase gene (GBA1), which encodes the lysosomal enzyme \u03b2-glucocerebrosidase (GCase), are a genetic risk factor for Parkinson's disease (PD). The pathophysiological consequences of GBA1 mutations on dopaminergic neuronal function, especially their impact on lysosomal function, mitophagy, and mitochondrial bioenergetics, remain unclear. Fibroblasts and dopaminergic neurons generated from induced pluripotent stem cells (iPSCs) derived from patients with\u00a0GBA1-PD were used in the study. Live-cell imaging was performed to measure lysosomal acidification, protease activity, mitochondrial membrane potential, and mitophagy. Mitochondrial morphology and autophagic vesicles were examined using transmission electron microscopy. Oxygen consumption rate was measured by Seahorse assay. V-ATPase assembly was quantified using fluorescence lifetime imaging with F\u00f6rster resonance energy transfer (FLIM-FRET), and pharmacological interventions included rapamycin and acidic nanoparticles. GCase activity, lysosomal acidification, protease activity, mitophagy and mitochondrial bioenergetic function were all impaired in GBA1 mutant dopaminergic neurons. Mitochondria were fragmented, with reduced membrane potential and oxygen consumption. Mechanistic target of rapamycin complex 1 (MTORC1) was constitutively phosphorylated and FLIM-FRET measurements confirmed impairment of lysosomal V-ATPase assembly, which was reversed by rapamycin treatment. Rapamycin and lysosome-targeting acidic nanoparticles rescued lysosomal pH and restored mitophagy, mitochondrial membrane potential and mitochondrial oxidative phosphorylation complex level in the GBA1 mutant dopaminergic neurons. We revealed a novel mechanistic link between GBA1 mutations and mitochondrial dysfunction, as the disruption of V-ATPase assembly driven by MTORC1 activation impairs lysosomal acidification. This causes impairment of mitophagy, leading to mitochondrial dysfunction, undermining dopaminergic cell function and fate. Pharmacological intervention with rapamycin or acidic nanoparticles restores lysosomal pH and rescue mitochondrial function, representing a novel therapeutic approach for\u00a0GBA1-PD .\n\nID: 42307976\nTitle: Personalized Pathogenic Nanoplastic Coronas Orchestrate Efferocytosis-Driven Immune Evasion in Lung Adenocarcinoma.\nAbstract: Airborne nanoplastic (NP) pollution is an emerging threat to respiratory health. Although inhaled NPs rapidly acquire a protein corona that shapes their bioactivity, the consequences of this process in cancer-susceptible lungs remain unclear. Here, we investigated whether NPs form a disease-specific pathogenic protein corona in lung adenocarcinoma that rewires immune signaling and accelerates tumor progression. Polyethylene terephthalate (PET) NPs were generated by mechanical fragmentation and extensively characterized. In tumor-bearing mice, inhaled PET NPs accelerated tumor growth relative to controls. Proteomic analysis of PET NPs incubated with bronchoalveolar lavage fluid from patients with lung adenocarcinoma identified lysozyme (LYZ) as a selectively enriched corona component associated with tumor stage and metastasis. Corona formation induced conformational remodeling of LYZ, enhanced its enzymatic activity, and prolonged its membrane retention. Mechanistically, corona-bound LYZ engaged Toll-like receptor 4 and activated a PGRN-LXR\u03b1 signaling axis, thereby increasing lysosomal acidification-dependent efferocytosis, promoting M2 macrophage polarization, and reducing CD8+ T-cell infiltration. In vivo, AAV9-mediated knockdown of LYZ or PGRN attenuated PET NP-induced efferocytosis, reversed immunosuppressive reprogramming, restored CD8+ T-cell infiltration, and suppressed tumor growth, demonstrating the functional requirement for this corona pathway. These findings establish disease-derived PET NP coronas as active nano-bio interfaces that connect environmental PET NP exposure with efferocytosis-driven immune evasion in lung adenocarcinoma. This work provides a mechanistic link between airborne NPs and tumor progression in susceptible hosts and highlights corona-mediated signaling as a potential therapeutic target and environmental health concern.\n\nID: 42176760\nTitle: Self-nanonizing gelatin oleyl conjugate solid dispersions for enhanced solubility and permeability of tetrabenazine.\nAbstract: The oral delivery of tetrabenazine (TBZ), a weakly basic drug, is markedly affected by its poor permeability and solubility, particularly under neutral pH conditions. This study aimed to design self-nanonizing solid dispersions (SDs) using a fattigated gelatin-oleic acid conjugate (GOC) to achieve a synergistic enhancement of the solubility and permeability of TBZ. Successful conjugation of amphiphilic GOC through N-acylation was confirmed using Fourier transform-infrared and proton nuclear magnetic resonance spectroscopies. Binary GOC-based SDs prepared by spray drying could encapsulate the drug into self-assembled nanoparticles, forming approximately 130\u00a0nm above critical micellar concentration (0.887\u00a0mg/mL) and enabling enhanced drug release of 62.38\u00a0\u00b1\u00a01.14% for 120\u00a0min with minimized drug precipitation in aqueous media. Furthermore, ternary SDs incorporating fumaric acid (Fu) as a microenvironmental pH (pHm) modifier showed the highest improvement of dissolution rate and permeability, achieving a 9-fold increased release of 85.32\u00a0\u00b1\u00a02.76% within 120\u00a0min and a 2.4-fold increase in transmembrane permeability compared to pure TBZ. Reduced crystallinity and increased affinity through hydrogen-bonded molecular dispersion of TBZ into the hydrophobic oleyl cores of GOC and the formation of an amorphous drug-Fu electrostatic complex are also crucial, boosting encapsulation efficiency and dissolution rates by producing approximately 170\u00a0nm-sized nanoparticles. Collectively, the current self-nanonizing SD system resolved the solubility and permeability issues associated with TBZ to improve oral drug treatment.\n\nID: 42059600\nTitle: Near-Infrared Upconversion Modulation of Intracellular Protons for Autophagy-Induced Apoptosis.\nAbstract: Protons critically regulate cancer cell behavior, metabolism, and signaling pathways, making intracellular pH modulation a promising therapeutic strategy. Yet, precise spatiotemporal control of proton levels remains a formidable challenge. In this study, we introduce a near-infrared (NIR)-controlled nanoscale proton delivery system using upconversion nanoparticles (UCNPs) coated with photoacid (PA) and ferrocene (Fc). Upon 980\u00a0nm NIR stimulation, UCNPs emit UV-visible emission (300-500\u00a0nm), activating surface-bound PA to induce transient H+ release and acidify the tumor microenvironment in vivo. This acute acidic stress reduces tumor cell glucose uptake by 50% and suppresses mechanistic target of rapamycin (mTOR) signaling, triggering excessive autophagy that functionally drives mitochondrial dysfunction and intrinsic apoptosis-a process we define as proton-mediated autophagy-induced apoptosis (PAA). Fc, a biodegradable peroxidase mimic and a non-fluorescent quencher, is incorporated to enable real-time visual quantification of proton accumulation via H+-triggered biodegradation, restoring the NIR upconversion luminescence (at 800\u00a0nm) of UCNPs. Following intravenous administration, the nanoagent achieves a six-fold reduction in tumor weight and elevates proton levels in glioma, effectively triggering PAA under non-invasive NIR irradiation. This work establishes a spatiotemporally controlled platform for intratumoral proton dynamics, enabling precision cancer theranostics.\n\nID: 42009103\nTitle: Nanoplastics exposure accelerates the progression of osteoarthritis via lysosomal destabilization-mediated pyroptosis.\nAbstract: Nanoplastics (NPs), as emerging environmental pollutants, are increasingly detected in human musculoskeletal tissues, but their impact on osteoarthritis (OA) pathogenesis remains unclear. This study aimed to investigate whether NPs exposure accelerates osteoarthritis progression in osteoarthritic mice, to elucidate the underlying molecular mechanisms, and to evaluate the therapeutic potential of quercetin. OA was induced in C57BL/6 mice via destabilization of the medial meniscus (DMM), with or without exposure to 20-nm polystyrene NPs (0.5\u00a0mg/mL in drinking water). For therapeutic intervention, quercetin (25 or 50\u00a0mg/kg) or indomethacin (3\u00a0mg/kg) was administered daily. Cartilage destruction was assessed by histology using the Osteoarthritis Research Society International (OARSI) scoring system, immunohistochemistry, and X-ray. In vitro, primary murine chondrocytes were treated with NPs and/or quercetin. Mechanisms were investigated using transmission electron microscopy, immunofluorescence, Western blot, organelle staining, and siRNA knockdown. NPs exposure significantly accelerated cartilage degradation and OA progression in DMM mice. Internalized NPs accumulated in chondrocyte lysosomes, inducing lysosomal membrane permeabilization (LMP), cathepsin B release, and subsequent NLRP3 inflammasome activation, leading to pyroptosis (evidenced by cleavage of gasdermin D N-terminal, GSDMD-N) and extracellular matrix loss. Quercetin restored lysosomal integrity, inhibited the LMP-NLRP3-pyroptosis axis in chondrocytes, and markedly attenuated NPs-aggravated cartilage destruction in vivo. This study identifies nanoplastics as novel environmental risk factors that act as pathological amplifiers in the context of osteoarthritis by inducing lysosomal destabilization-mediated pyroptosis in chondrocytes. Quercetin alleviates this pathological cascade by stabilizing lysosomes, highlighting its potential as a therapeutic agent against nanoplastics-exacerbated OA.\n\nID: 41950681\nTitle: A covalent organic framework nano-chelator orchestrates multitarget clearance of Alzheimer's pathologies.\nAbstract: Metal ion dysregulation is a critical pathological driver and a promising therapeutic target in Alzheimer's disease (AD). This study presents a novel multifunctional nanoplatform based on a covalent organic framework functionalized with 8-hydroxyquinoline (COF-HQ), engineered to simultaneously address the multifaceted pathology of AD. The material not only effectively chelates Cu2+ to inhibit and reverse Cu2+-induced amyloid-\u03b2 (A\u03b2) aggregation but also, upon coordination, forms a complex with potent superoxide dismutase (SOD)-mimetic activity. This catalytic function enables the continuous scavenging of reactive oxygen species (ROS), thereby alleviating oxidative stress in the neuronal microenvironment. Furthermore, COF-HQ drives microglial polarization from the pro-inflammatory M1 to the anti-inflammatory M2 state and restores lysosomal acidification and function impaired by A\u03b2-Cu2+, thereby enhancing microglial phagocytosis and clearance of A\u03b2 to break the vicious cycle of impaired degradation. The multivalent porous architecture of the COF scaffold provides enhanced binding capacity and stability, resulting in superior anti-aggregation, antioxidant, and cytoprotective efficacy compared to its molecular building block. In vivo studies demonstrate that systemic administration of COF-HQ significantly improves cognitive performance in behavioral tests, reduces cerebral A\u03b2 plaque burden, and attenuates synaptic and neuronal loss in an AD mouse model. This work establishes a new COF-based therapeutic paradigm that concurrently targets metal dyshomeostasis, protein misfolding, oxidative stress, and defective cellular clearance, offering a comprehensive and integrated nanotherapeutic strategy for AD.\n\nID: 41904737\nTitle: Assessment of female fertility and oocyte quality in mice after exposure to polystyrene microplastics and polybrominated diphenyl ethers, alone and in combination.\nAbstract: With the extensive use of plastics and brominated flame retardants, polystyrene microplastics (Ps-MPs) and polybrominated diphenyl ethers (PBDEs) frequently co-occur in the environment, raising growing concerns about their combined reproductive hazards. However, the synergistic toxicity of Ps-MPs and PBDEs on female fertility and oocyte quality remains insufficiently characterized. In this study, we established a 28-day oral exposure model in female ICR mice to evaluate the effects of Ps-MPs, PBDE-47, and their co-exposure on ovarian function, oocyte meiotic competence, and reproductive outcomes. Both Ps-MPs and PBDE-47 alone reduced ovarian weight, decreased antral follicles, increased follicular atresia, and markedly lowered ovulation and litter size, whereas co-exposure produced the most severe impairments. At the oocyte level, exposure significantly reduced germinal vesicle breakdown and first polar body extrusion, increased abnormal spindle formation and erroneous kinetochore-microtubule attachments, and suppressed TPX2 expression and \u03b1-tubulin acetylation. Cortical F-actin polarization, spindle migration, and membrane localization of JUNO and ovastacin were also disrupted, indicating widespread defects in meiotic and membrane maturation. Mechanistically, Ps-MPs and PBDE-47 induced a decline in mitochondrial membrane potential, aberrant mitochondrial distribution, excessive lipid accumulation, and Ca\u00b2\u207a imbalance, accompanied by autophagosome accumulation, lysosomal dysfunction, elevated ROS, increased \u03b3-H2AX signals, and enhanced Annexin V labeling, ultimately triggering DNA damage and apoptosis. All alterations were most pronounced under co-exposure. Collectively, Ps-MPs and PBDE-47 synergistically impair female fertility by converging on mitochondrial dysfunction, autophagy-lysosome imbalance, and oxidative stress-mediated DNA damage, leading to substantial reductions in oocyte quality. These findings provide key mechanistic evidence for evaluating reproductive risks associated with real-world mixtures of microplastics and persistent organic pollutants.\n\nID: 41859345\nTitle: Long-term ion release, fluoride recharge, pH modulation, and mechanical aging of an experimental ACP-based composite compared with contemporary bioactive restorative materials.\nAbstract: This study evaluated the 12-month ion release, fluoride recharge capacity, pH modulation, mechanical aging, and structural reliability of an experimental amorphous calcium phosphate (ACP)-based composite compared to contemporary bioactive restorative materials. An experimental ACP composite was compared with Activa\u2122 BioACTIVE-Restorative, Cention N, and Surefil one \u2122. Calcium (Ca2+), phosphate (PO4 3-), and fluoride (F-) release, along with pH changes, were assessed over 365 days in artificial saliva. Fluoride recharge was performed at six months using a single application of 5000\u00a0ppm sodium fluoride gel, followed by cumulative fluoride re-release measurement for 30 days. The flexural strength and modulus were evaluated at baseline, 6 months, and 12 months. Statistical analysis was conducted using mixed-model ANOVA with post-hoc tests, and flexural strength reliability was assessed using Weibull analysis (\u03b1\u00a0=\u00a00.05). All materials exhibited an initial burst of ion release, followed by a progressive decline (p\u00a0=\u00a00.001). The ACP composite demonstrated the highest early calcium and phosphate release but negligible fluoride release and significant reductions in mechanical properties and reliability after aging. Cention N showed sustained multi-ion release, the greatest alkalizing capacity, and stable mechanical performance. Surefil one\u2122 achieved the highest fluoride release and recharge capacity while maintaining a near-neutral pH and superior mechanical reliability. The Activa\u2122 BioACTIVE-Restorative exhibited moderate ion release and intermediate mechanical performance. Bioactive restorative materials exhibit distinct material-dependent behaviors. Alkasite-based systems showed balanced ion release and mechanical stability, fluoride-focused systems demonstrated superior recharge and reliability, and the ACP composite provided primarily short-term calcium-phosphate release with limited long-term durability.\n\nID: 41702167\nTitle: Lipid metabolic dysregulation: A novel developmental toxicity pathway of aged nanoplastics via inhibition of lipophagy in zebrafish.\nAbstract: The widespread occurrence of micro/nanoplastics (MNPs) in ecosystems poses significant environmental challenges. Although environmentally aged MNPs predominate, their developmental toxicity remains poorly understood. We demonstrate that both pristine and aged polystyrene nanoplastics (PSNPs) induce abnormal lipid accumulation and impair early development in zebrafish larvae. Lipidomics revealed aged PSNPs significantly increased triglycerides via disrupted glycerophospholipid metabolism. Mechanistically, aged PSNPs did not alter LC3-II/LC3-I ratios but upregulated RAB7 and p62 while downregulating lysosomal biogenesis regulator TFEB. They also reduced ATG5, essential for autophagosome formation via LC3 lipidation. These molecular alterations, together with lysosomal inhibition assays, functionally support lysosomal dysfunction as a key constraint on lipophagy. This impairment inhibits lipid utilization, promotes accumulation, and disrupts development. Critically, aged PSNPs caused stronger disruption than pristine particles despite both interfering with lipophagy. Our study provides mechanistic insights into the developmental toxicity of UV-aged PSNPs in zebrafish, highlighting the importance of considering aging-related changes in nanoplastic risk evaluation. SYNOPSIS: Aged nanoplastics exacerbate developmental toxicity in zebrafish by suppressing lipophagy to drive lipid accumulation, underscoring ecological risks in aquatic systems.\n\nID: 41643617\nTitle: Early-life exposure to polystyrene nanoplastics at ambient doses induces neurotoxicity via mTOR-mediated autophagy-lysosomal dysfunction and proteostasis imbalance.\nAbstract: Nanoplastics are an emerging global environmental concern, with increasing evidence of their neurotoxic effects. Recent findings suggest that abnormal aggregation of pathogenic proteins within the nervous system may contribute to the neurotoxicity induced by nanoplastics, yet the molecular mechanisms regulating this pathological cascade remain unclear. Here, we used immature mice as an experimental model to represent infants and young children who are at higher risk of nanoplastics exposure, to elucidate the molecular mechanisms underlying neurotoxicity induced by exposure to polystyrene nanoplastics (PS-NPs) during early life. The results showed that environmentally relevant doses of PS-NPs penetrated the brains of immature mice and induced behavioral and emotional disorders. Proteomic analysis identified the mTOR signaling pathway as a candidate pathway responding to PS-NPs exposure in the immature mouse brain. Rapamycin intervention and quantitative validation further demonstrated that PS-NPs exposure upregulated mTOR signaling, thereby leading to lysosomal dysfunction and a blockade of autophagic flux, which in turn disrupted proteostasis and ultimately caused neurotoxicity. Furthermore, treatment with sodium 4-phenylbutyrate (4-PBA) confirmed that proteostasis imbalance, characterized by activation of the unfolded protein response, was a direct driver of this neurotoxicity. Notably, both rapamycin and 4-PBA treatments alleviated neurotoxicity resulting from PS-NPs exposure by restoring proteostasis. Together, these findings highlight dysregulation of the autophagy-lysosome pathway mediated by mTOR as a central mechanism of PS-NPs-induced neurotoxicity in immature mice and suggest lysosomal regulation for proteostasis remodeling as a prospective therapeutic strategy against neurological hazards related to nanoplastics.\n\nID: 41622846\nTitle: pH-Mediated Strong Metal-Support Interaction Construction Through Dynamic Fermi Level Tuning.\nAbstract: The metal-support interface is central to governing catalytic transformations. While strong metal-support interaction (SMSI) is an established strategy to tailor the morphology and electronic properties of supported metal catalysts, the role of interfacial charge redistribution in SMSI formation remains poorly understood and rarely leveraged. Here, we report a dual-stimuli approach that combines pH modulation with ultrasonication to mediate SMSI construction in aqueous solution through dynamic Fermi level tuning. By leveraging in situ pH-driven charge redistribution at the metal-support interface, we achieve controllable SMSI encapsulation of metal nanoparticles, as verified by electrochemical analysis, work function measurements, and x-ray-based techniques. The resulting catalysts exhibit tunable SMSI features and deliver enhanced activity and selectivity in hydrogenation reactions. This work establishes a facile strategy to modulate catalyst structure and electronic properties by exploiting Fermi level variation as a driving force, thereby advancing rational SMSI design and catalytic performance across diverse environments.\n\nID: 41483106\nTitle: Hepatotoxic mechanisms of functionalized nanopolystyrene: decoding the role of ionic surface groups.\nAbstract: With annual global plastic production exceeding 400 million tons, nanoscale polystyrene particles (nPS) have become a major health concern due to their bioaccumulation capacity and ability to cross biological barriers. Surface-charged nPS variants (cationic, anionic, and neutral) show distinct biodistribution patterns, yet the mechanisms underlying their systemic damage remain incompletely understood. This study aimed to investigate the systemic injury mechanisms of nPS with different surface charges. Mice were exposed to fluorescently labeled cationic (amino-modified), anionic (carboxyl-modified), and neutral nPS via drinking water (25\u00a0mg/mL) for 3\u00a0weeks. Tissue distribution was analyzed using fluorescence microscopy; pathological changes were assessed via hematoxylin-eosin (HE) staining; metabolic perturbations were detected by metabolomic profiling. Mechanistic investigations were performed using metabolomics, flow cytometry, and molecular assays in AML12 hepatocytes and vascular endothelial cells. Fluorescence microscopy showed neutral nPS accumulated in the vascular endothelium of the stomach, intestine, and lung via passive diffusion, while cationic/anionic nPS penetrated hepatic sinusoids through charge-mediated interactions. HE staining revealed severe liver injury, with no significant abnormalities in other tissues. Metabolomic profiling indicated disrupted hepatic amino acid and lipid metabolism, depleted antioxidants (e.g., vitamin E and glutathione), and induced oxidative stress (evidenced by elevated hydroxy fatty acids). In hepatocytes, nPS-induced endoplasmic reticulum (ER) stress triggered excessive reactive oxygen species (ROS) production, inhibiting SLC7A11-mediated cystine uptake and glutathione synthesis, leading to disulfide stress (\u03b2-actin disulfide mispairing) and ferroptosis (GPX4 inactivation and iron accumulation). In contrast, neutral nPS induced endothelial cell senescence via phagolysosome dysfunction, causing lysosomal membrane permeabilization and \u03b2-galactosidase release. This study identifies a \"charge-specific injury\" paradigm: charged nPS induce hepatocyte ferroptosis via an ER stress-disulfide stress cascade, while neutral nPS trigger endothelial senescence through phagocytic dysfunction. These findings provide critical insights for the biosafety assessment of nanoplastics and identify potential targets for preventing plastic pollution-related liver diseases.\n\nID: 41457494\nTitle: Coexposure of Micro and Nano-Plastics with Pesticides: Cytotoxicity and Bioaccumulation Effects on a Fish Intestinal Cell Line.\nAbstract: Micro- and nanoplastics (MNPs) occur in aquatic environments and accumulate in fish. MNPs can also adsorb other contaminants present in aquatic environments, and there is limited information on exposure scenarios involving MNP and pesticide mixtures. Ultraviolet (UV) radiation and chemical oxidation of MNPs can affect the sorption properties of MNPs and chemicals, thus altering the exposure and effects on fish. Our study investigated the toxicity and bioaccumulation of a lindane and dichlorodiphenyldichloroethylene (DDE) mixture adsorbed onto pristine and weathered polyethylene (PE) MNPs. Three different PE MNP types were used: microplastics (2-10 \u03bcm), oxidized microplastics (10-15 \u03bcm), and a MNP mixture (0.2-9.9 \u03bcm), and additionally each type was UV-aged for comparisons. RTgutGC cells, derived from rainbow trout (Oncorhynchus mykiss) intestine, were used to evaluate the role of the particle type on pesticides bioaccumulation and toxicity. Results showed that UV aging did not affect the agglomeration in solution but decreased the MNP's capacity to adsorb the pesticides (i.e., non-aged adsorbed 35% and 69% and UV-aged adsorbed 9.7% and 63% of lindane and DDE, respectively) likely due to a shift in MNPs hydrophobicity and consequently reduced the cytotoxicity of the pesticide MNPs mixture. Nanoplastics induced approximately 20% more lysosomal damage than microplastics, suggesting a distinct toxicity mechanism. Fluorescently labeled MNPs accumulated in intestinal cells which confirmed the internalization. Finally, bioaccumulation of DDE decreased approximately 2 to 8-fold in cells coexposed with all particle types, although lindane was not detected in the cells. Overall, our study indicated that MP and NPs reduce bioavailability of pesticides, but UV aging and particle fragmentation to nano size increased their bioaccumulation and toxicity in fish intestinal cells.\n\nID: 41416489\nTitle: Reshape Intracellular/Extracellular pH for Enhanced Nanocatalytic Ferroptosis and cGAS-STING Activation Induced Immunotherapy.\nAbstract: Nanometal-based therapies face challenges arising from the overexpression of proton efflux transporters in cancer cells, which acidifies the extracellular tumor microenvironment (TME) while preserving a relatively neutral intracellular pH, thereby compromising therapeutic efficacy and fostering an immunosuppressive TME. Here, we integrate the proton pump inhibitor pantoprazole (PTZ) with manganese ferrite nanoparticles (MFNs) within an acidity-responsive polymer for enhanced ferroptosis and cGAS-STING activation mediated immunotherapy. This assembly (PTZ/MFNAs) facilitates tumor accumulation through the enhanced permeability and retention effect while initially restricting the release of metal ions. Upon reaching the tumor site, PTZ release increases intracellular acidity, which further triggers assembly disintegration, accelerates the release of iron and manganese ions, and neutralizes the extracellular microenvironment to alleviate immunosuppression. The released manganese ions synergistically collaborate with iron ions to amplify reactive oxygen species (ROS) generation for ferroptosis while activating the cyclic guanosine monophosphate-adenosine monophosphate synthase-stimulator of interferon genes (cGAS-STING) pathway, stimulating innate immunity. This potentiation of innate immunity, coupled with the reversal of TME immunosuppression, collectively and effectively inhibits tumor growth and metastasis. Therefore, the PTZ/MFNAs co-delivery system represents a promising pH-modulation strategy to enhance iron/manganese ions-mediated ferroptosis and cGAS-STING activation-induced immunotherapy.\n\nID: 41344183\nTitle: When nanoplastics (NPs) meet algae: Heteroaggregates exacerbate bioaccumulation, immunotoxicity, and microbial dysbiosis in the green mussel (Perna viridis).\nAbstract: Heteroaggregates (HAs) formed by nanoplastics (NPs) and microalgae occur ubiquitously in natural aquatic systems. However, their influence on the toxicokinetics and biological effects of NPs in marine mussels remains largely unknown. Here, the green mussels (Perna viridis) were exposed to NPs and HAs at their environmentally relevant concentrations for 21 d, followed by a 7-d depuration phase. The effects on toxicokinetics, immunological responses, and microbiota of digestive gland were evaluated. The results showed that HAs increased the uptake rate constant in digestive gland by 5.5-fold and tissue accumulation of NPs by 2.5-fold compared to NPs alone, resulting in higher NPs burdens after depuration. Meanwhile, HAs exacerbated NPs-induced immunotoxicity, including increased hemocyte mortality and ROS production, and decreased phagocytosis and lysosomal membrane stability. Moreover, HAs led to more pronounced dysbiosis of microbiota in digestive gland than NPs alone, reducing fungal diversity by 56\u202f% and enriching opportunistic fungal pathogens such as Fusarium, while bacterial communities showed minor shifts. This study has provided critical evidence that HAs act as a \"Trojan horse,\" exacerbating NPs risks. This study highlights the necessity of adding the naturally occurring HAs into the ecological risk assessment framework of NPs, especially for benthic filter-feeding organisms.\n\nID: 41247156\nTitle: Mesenchymal stem cell-derived nanovesicles coated PLGA nanoparticle (MSC-PLGA-NPs) remodel lysosomal function to clear pathological proteins in Alzheimer's disease models.\nAbstract: To develop a novel multifunctional nanoparticle platform by combining mesenchymal stem cell-derived nanovesicles (MSC-NVs) with poly(lactic-coglycolic acid) (PLGA) nanoparticles for Alzheimer's disease (AD) therapy. Mesenchymal stem cell-derived nanovesicle-poly(lactic-coglycolic acid) nanoparticles (MSC-PLGA-NPs) were prepared via sonication-loading. Blood-brain barrier (BBB) penetration was evaluated using in vitro transwell models and in vivo mouse models. Lysosomal function, autophagy, pathological protein clearance, and anti-inflammatory effects were assessed using various cellular and molecular biology techniques. MSC-PLGA-NPs demonstrated 2.3-fold higher BBB penetration efficiency compared to PLGA alone. In a chloroquine(CQ)-induced lysosomal injury model and mice model, they effectively restored lysosomal pH, enhanced autophagy (reducing LC3-II/I ratio by 0.4-fold and p62 expression by 52%), cleared amyloid precursor protein (APP) and phosphorylated tau (p-tau) proteins, and inhibited IL-6 and TNF-\u03b1 without hepatorenal toxicity. These results demonstrate that MSC-PLGA-NPs, a novel multifunctional nanoparticle platform, synergistically integrates the BBB penetration capability of MSC-NVs and the lysosomal acidification function of PLGA. The synergistic combination represents a pioneering \"delivery-repair-clearance\" integrated strategy for AD therapy. Offering significant advantages over single-component approaches, MSC-PLGA-NPs provide a promising preclinical candidate and new insight into lysosome-targeted nanomedicines for neurodegenerative diseases.\n\nID: 41115343\nTitle: Cytotoxicity of polystyrene nanoplastics involves mitochondrial dysfunction and DNA damage in hemocytes of the Pacific oyster.\nAbstract: Nanoplastics represent an increasing ecological threat to marine ecosystems, with the potential to disrupt immune responses, oxidative stress pathways, and bioenergetics. We employed an in vitro cellular bioassay to investigate the distribution, metabolic disruption, and genotoxicity resulting from 24\u202fh of exposure to polystyrene nanoplastics (NanoPS, approximately 90\u202fnm) in the hemocytes of the Pacific oyster (Crassostrea gigas). Transmission electron microscopy suggested the internalization and distribution of NanoPS within vesicles, the cytosol, and the nuclei of exposed hemocytes. Cytotoxicity assays revealed that metabolic activity (resazurin assay, LC50\u202f= 91.6\u202fmg/L) was more sensitive than lysosomal integrity (neutral red assay, LC50\u202f= 252.3\u202fmg/L). Exposure to NanoPS also increased the levels of reactive oxygen species and DNA damage as low as 1.2\u202fmg/L. Metabolic assays revealed that enhancing mitochondrial metabolism through galactose supplementation increased the cytotoxicity and DNA damage caused by NanoPS. Conversely, promoting anaerobic metabolism with glucose supplementation reduced these effects. Co-exposures with the mitochondrial uncoupler FCCP did not decrease cellular viability but elevated DNA damage. We suggest that mitochondria are a sensitive target of nanoplastics in bivalve hemocytes, highlighting the importance of considering aerobic metabolism in assessing nanoplastic toxicity. The strong correlation with the published in vivo effects of this same NanoPS highlights the biological relevance of this cellular toxicity assessment. This research supports the use of hemocyte-based cellular assays to complement in vivo studies for characterizing nanoplastic toxicity mechanisms in marine organisms.\n\nID: 41093227\nTitle: Hitchhikers in bivalve immune system: Mixed microplastics and nanoplastics triggers hemocyte autophagy.\nAbstract: Natural microplastic and nanoplastics (MNPs) mixtures generally consist of multiple sizes, but how their co-existence influences the immune system of aquatic organisms remains elusive. Here, we quantitatively tracked and demonstrated that such heterogeneity dynamically reshaped bivalve hemocyte burden in non-additive modes with subpopulation-specific consequences for immune function. Kinetic modeling revealed distinct internalization patterns and selectivity among hemocyte subpopulations, driven by particle proportions and uptake dynamics. Granulocytes displayed indiscriminate capacity for MNP internalization, maintaining high uptake efficiency across varying particle compositions. In contrast, semigranulocytes showed selective internalization behavior sensitive to particle size distributions, facilitating preferential uptake shifts as nanoparticle proportions varied. Mechanistically, large NPs accelerated the internalization of smaller NPs via a hitchhiking effect but simultaneously competed for intracellular processing pathways, limiting maximal uptake. Notably, co-exposure with smaller NPs significantly enhanced and accelerated MPs internalization, leading to intracellular overload with severe lysosomal damage and mitochondrial impairment. These disruptions potentially triggered mitochondria-lysosome crosstalk and autophagy, particularly pronounced in semigranulocytes. Ultimately, the combined presence of multiple particle sizes resulted in cascading impairment of hemocyte phagocytic capacity than exposure to individual particles alone, highlighting particle-size interactions as critical determinants of immunotoxicity. Our findings underscored how coordinated disposal of hemocyte subpopulations influenced the mixed-size plastic clearance, providing new insight on the health risks posed by MNPs to marine organisms.\n\nID: 41069155\nTitle: Visual Whole-Process Monitoring Dynamic Phase Separation of Autophagic Lysosomes in Alzheimer's Disease by a Lysosome-Targeted pH-Activated Fluorescence Probe.\nAbstract: Although liquid-liquid phase separation (LLPS) of amyloid-\u03b2 (A\u03b2) aggregates is a critical driver of Alzheimer's disease (AD) progression, the role of lysosomal acidification defects remains poorly understood during this process. Herein, we successfully develop a synthetic strategy involving the construction of pH-activated probe backbones by the atom transfer radical polymerization technique with methacrylates with different substituents as monomers. Subsequently, a fluorescence probe is prepared by integrating hydrophobic aggregation-induced luminescence (AIE) fluorescence dyes and aggregation-induced bursting (ACQ) dyes into ACQ/AIE ratio imaging nanoparticles through covalent bonding and self-assembly techniques. Such AIE probe can monitor lysosomal acidification defects in AD and elucidate their role in A\u03b2 phase separation. Interestingly, our new findings reveal that A\u03b2 accumulation synergizes with lysosomal dysfunction (the pH value itself has not changed) to induce pathological LLPS, thereby providing a novel approach for phase modulation and attenuating AD progression. Taken together, our design concept provides a novel strategy to regulate phase separation, potentially reducing or delaying A\u03b2 aggregation and AD progression.\n\nID: 41038372\nTitle: Lysosomal dependent transcytosis of polystyrene nanoplastics within macrophages.\nAbstract: As emerging pollutants, nanoplastics (NPs) have emerged as significant environmental pollutants with potential health risks and have been largely investigated owing to their distinctive physicochemical properties and ubiquitous environmental distribution. However, research on the intracellular complete migration of NPs is limited, particularly with respect to exocytosis. Here, we exposed human macrophages to polystyrene nanoplastics (PS-NPs) and observed that PS-NPs induced the accumulation of lysosomes within the cells and lead to an increase in their contents. Additionally, PS-NPs co-localized with lysosomes and triggered lysosomal activation. Using a previously established method for PS-NPs adsorption to intracellular proteins and employing proteomic and bioinformatic approaches, we confirmed that after entering the cell, PS-NPs predominantly adsorbed proteins related to the lysosomal pathway, and stably adsorbed the key lysosomal protein cathepsin D (CTSD). Further studies identified that PS-NPs induced lysosomal exocytosis, during which the lysosomal-specific mature-CTSD adsorbed onto PS-NPs and was co-released from the cell. This process was mediated by Ca2+. In summary, this study elucidated the lysosome-dependent transcytosis of PS-NPs and established a novel method for verifying lysosomal exocytosis using mature-CTSD as a marker.\n\nID: 40943372\nTitle: Acute Toxicity of Metal Oxide Nanoparticles-Role of Intracellular Localization In Vitro in Lung Epithelial Cells.\nAbstract: Endocytic uptake and lysosomal localization are suggested to be the key mechanisms underlying the toxicity of metal oxide nanoparticles (MONPs), with dissolution in the acidic milieu driving the response. In this study, we aimed to investigate if MONPs of varying solubility are similarly sequestered intracellularly, including in lysosomes and the role of the acidic lysosomal milieu on toxicity induced by copper oxide (CuO) nanoparticles (NPs), nickel oxide (NiO) NPs, aluminum oxide (Al2O3) NPs, and titanium dioxide (TiO2) NPs of varying solubility in FE1 lung epithelial cells. Mitsui-7 multi-walled carbon nanotubes (MWCNTs) served as contrasts against particles. Enhanced darkfield hyperspectral imaging (EDF-HSI) with fluorescence microscopy was used to determine their potential association with lysosomes. The v-ATPase inhibitor Bafilomycin A1 (BaFA1) was used to assess the role of lysosomal acidification on toxicity. The results showed co-localization of all MONPs with lysosomes, with insoluble TiO2 NPs showing the greatest co-localization. However, only acute toxicity induced by soluble CuO NPs was affected by the presence of BaFA1, showing a 14% improvement in relative survival. In addition, all MONPs were found to be associated with large actin aggregates; however, treatment with insoluble TiO2 NPs, but not soluble CuO NPs, impaired the organization of F-actin and \u03b1-tubulin. These results indicate that MONPs are sequestered similarly intracellularly; however, the nature or magnitude of their toxicity is not similarly impacted by it. Future studies involving a broader variety of NPs are needed to fully understand the role of differential sequestration of NPs on cellular toxicity.\n\nID: 40782538\nTitle: Polystyrene nanoplastics-induced methuosis in brain microvascular endothelial cells: Rescue via ESCRT membrane repair system.\nAbstract: Nanoplastic pollution has emerged as a significant environmental concern, with increasing evidence suggesting that these nanoparticles can disrupt the blood-brain barrier (BBB) and accumulate in the brain, ultimately leading to neurological impairment. However, the underlying mechanism for the toxic effects of nanoplastics on the BBB remain poorly understood. In this study, we explored the toxic effects of polystyrene nanoplastic (PSNP) on brain microvascular endothelial cells (BMECs), one of the most critical components for maintaining BBB integrity. Our results revealed that PSNP specifically accumulate in the endolysosomal system following their internalization by BMECs. This accumulation disrupts lysosomal function and blocks endolysosomal pathways, ultimately triggering methuosis-a unique form of cell death characterized by extensive cytoplasmic vacuolization. Although the endosomal sorting complexes required for transport (ESCRT) system is naturally activated as a cellular defense mechanism, it is insufficient to repair PSNP-induced lysosomal membrane damage. By enhancing ESCRT activity, we effectively restored lysosomal function, thereby preventing cellular methuosis and preserving BBB integrity. Therefore, our findings provide crucial insights into the mechanisms underlying PSNP-induced BBB disruption by focusing on methuosis in endothelial cells. These insights hold important implications for environmental toxicology and public health in the context of global plastic pollution.\n\nID: 40768614\nTitle: Engineered Stem Cell Membrane-Coated Nanodrugs for Targeted Therapy of Alzheimer's Disease.\nAbstract: The pathological complexity of Alzheimer's disease (AD) necessitates the development of efficient nanomedicine delivery systems. Nanoparticles are considered promising therapeutic candidates for AD owing to their drug-loading capacity. This study introduces an engineered cell membrane coating strategy to enhance nanoparticle functionality in targeting efficiency and susceptivity to immune clearance. We developed an engineered biomimetic nanodrug delivery system by modifying nanoparticles with Gas6-overexpressing neural stem cell membranes for improving microglia targeting, pro-phagocytic properties and immunomodulatory effects, constructing a composite system designated as Gas6-NV-NPs. The system employs poly(lactic-co-glycolic acid) (PLGA) as a carrier to coencapsulate Rapamycin (RAP) and nicotinamide riboside (NR) (referred to as NPs), while leveraging Gas6 protein to specifically bind microglial surface receptors, enabling precise targeting of AD pathological regions. Our findings demonstrated that Gas6-NV-NPs restored lysosomal acidification in microglia, enhanced microglial phagocytic clearance of amyloid-\u03b2 (A\u03b2), and reinstated the anti-inflammatory phenotype in BV2 microglial cells. Furthermore, Gas6-NV-NPs exhibited favorable biosafety and robust brain-targeting capability in vivo, effectively promoting A\u03b2 clearance and neuronal repair in 5 \u00d7 FAD mice model of AD. This \"engineered membrane modification-nanodrug delivery\" synergistic strategy enhances therapeutic targeting and achieves multitargeted effects, offering a approach to overcoming critical bottlenecks in AD nanotherapy.\n\nID: 40744315\nTitle: Human neurons are susceptible to the internalization of small-sized nanoplastics.\nAbstract: Environmental pollution caused by small plastics has become a social concern due to growing awareness of their adverse impacts on organisms, including humans. While the brain has been identified as a major site of small plastic accumulation, fundamental information about their impacts at the cellular level remains limited. In this study, we investigated the neuronal uptake and toxicity of nanoplastics using the human neurons (LUHMES). LUHMES cells internalized polystyrene (PS) nanoplastics with a preference for 50\u202fnm particles, mainly through clathrin-mediated endocytosis and macropinocytosis. However, PS uptake by LUHMES cells was lower than that by other neural cell types. PS nanoparticles were predominantly localized in lysosomes and minimally in mitochondria. On the other hand, PS nanoparticles had no obvious effects on acute cytotoxicity, neurite outgrowth, and oxidative stress. This study provides essential data on the neuronal responses to nanoplastics and highlights the need for further evaluation of their neurodevelopmental impact.\n\nID: 40716557\nTitle: Thermo stable ZnO NPs/Asiatic acid nanocomposites for acidogenic neutralization, anti-biofilm, and enamel protection in dental enamel reinforcement.\nAbstract: Dental caries, a pervasive oral health issue, is driven by Streptococcus mutans-mediated biofilm formation and acidogenesis, culminating in enamel demineralization and structural degradation. This study evaluates the efficacy of thermostable ZnO NPs/AA nanocomposites in suppressing S.mutans acid production, disrupting its biofilm matrix, and strengthening enamel integrity, with an emphasis on its potential as a novel dental healthcare material. This study encompassed the synthesis of zinc oxide nanoparticles functionalized with Asiatic acid (ZnO NPs/AA) using a co-precipitation method. The physicochemical properties of ZnO NPs/AA were characterized using FE-SEM with EDS, XRD, FT-IR, and UV-DRS, confirming structural integrity and functional modifications. Thermal stability was assessed via TGA and DSC, demonstrating robust performance suitable for biomedical applications. The antibacterial activity, anti-biofilm efficacy of ZnO NPs/AA including, extracellular polymeric substance inhibition, and acidogenic activity modulation were evaluated through microdilution methods, biofilm biomass quantification assays, Congo red binding studies, and pH analysis. In ex-vivo studies, ZnO NPs/AA treated sectioned tooth enamel was exposed to S. mutans to evaluate its effects. The mechanical properties, including microhardness and surface morphology, were analyzed using Vickers microhardness testing and Atomic Force Microscopy (AFM). Additionally, the controlled release kinetics of Asiatic acid were analyzed under physiological (pH 7.4) and acidic (pH 5.0) conditions to elucidate its pH-responsive drug delivery potential. A precisely synthesized ZnO NPs/AA with a sheet-assembled flower-like structure was observed through SEM analysis, while its composition and functionalization were further confirmed by FTIR and UV-DRS. Thermal stability was validated through TGA and DSC analyses, establishing ZnO NPs/AA as a highly thermally stable material for biomedical applications. ZnO NPs/AA exhibited remarkable multi-functional properties, including potent antibacterial activity, leading to an 85.25 % reduction in S. mutans biofilm biomass and an 81 % inhibition of EPS production. pH modulation studies demonstrated effective neutralization of acidogenic activity, maintaining a near-neutral pH (7.01 at 48 h), significantly outperforming ZnO NPs and the untreated control. Enamel treated with ZnO NPs/AA following exposure to S.mutans showed a 72.6 % increase in microhardness and a 80.93 % reduction in surface roughness, highlighting its ability to combat S.mutans induced demineralization and acid formation, thereby preserving the enamel integrity. This study establishes ZnO NPs/AA as a promising biomaterial with potent antibacterial, anti-biofilm, and enamel-protective properties. These findings highlight ZnO NPs/AA as a promising and innovative approach for mitigating enamel demineralization and combating biofilm-associated dental challenges. ZnO NPs/AA is a promising therapeutic option for protecting enamel, combating S. mutans biofilm damage, and improving dental health due to its stability, durability, and pH-responsive drug release.\n\nID: 40711377\nTitle: Glucose-Activated Fe-Cu Dual-Ion Nanozyme Cascade Reactor with Photothermal Enhancement for Antimicrobial Therapy in Diabetic Wound Healing.\nAbstract: Nanozyme technology offers promising avenues for the development of new antibacterial agents to combat antibiotic resistance. However, the antibacterial efficacy of nanozymes is constrained by their dependence on hydrogen peroxide (H2O2). In this study, a glucose-activatable nanoreactor (FCSGP NPs) with high antimicrobial efficiency and drug loading ability is designed to enhance the anti-infection effects in diabetic wound healing. Under hyperglycemic conditions, this nanoreactor initiates a sequential cascade reaction by consuming glucose, thereby amplifying the anti-infective effects. The glucose oxidase (GOx)-mediated glucose oxidation cascade produces both H2O2 (for the Fenton reaction) and gluconic acid (for pH modulation), synergistically enhancing chemodynamic therapy (CDT). The resulting acidic microenvironment accelerates the FCSGP nanoreactor degradation, triggering the glutathione (GSH)-induced release of Fe and Cu ions, which subsequently catalyze a Fenton-like reaction with H2O2 to generate a highly reactive hydroxyl radical (\u2022OH). Furthermore, the FCS-mediated photothermal (PTT) effect induces localized hyperthermia, which simultaneously enhances the GOx enzymatic activity and enables synergistic PTT-CDT. This combined action eradicates biofilm-associated infections in the absence of exogenous H2O2 while accelerating diabetic wound healing. By leveraging these synergistic cascade reactions, this endogenous enzyme-based strategy offers a promising platform for enhancing diabetic wound healing.\n\nID: 40706951\nTitle: Toxicological profiling of polystyrene microplastics in raw 264.7 macrophages: Linking microplastic exposure to immune cell impairment.\nAbstract: The pervasive presence of microplastics (MPs), particularly polystyrene microplastics (PSMPs), has raised urgent concerns regarding their effects on human health. This study investigates the toxicological effects of spherical PSMPs (<0.50\u202f\u00b5m) on Raw 264.7 murine macrophages, critical immune cells that actively internalize foreign materials. At exposure concentrations ranging from 50 to 500\u202f\u00b5g/mL, PSMPs were rapidly internalized within 2\u202fh, with accumulation increasing over time. Notably, high-dose exposure (500\u202f\u00b5g/mL) resulted in significant mitochondrial membrane damage, lysosomal dysfunction, elevated reactive oxygen species (ROS) levels, and lipid peroxidation. These cellular stress responses were accompanied by increased levels of LDH and SOD, as well as the induction of apoptosis and cellular senescence. The findings show that PSMPs disrupt mitochondrial function and contribute to senescence responses, ultimately compromising immune cell viability and function. This study provides new insight into the intracellular fate and toxicity of environmentally relevant PSMPs and emphasizes the need for urgent evaluation of plastic pollution's impact on human health.\n\nID: 40665500\nTitle: Reversibility of Renal Fibrosis Induced by Exposure to Polystyrene Nanoplastics: The Dual Role of Lysosomes.\nAbstract: It has been demonstrated that nanoplastics (NPs) can accumulate in the kidney and induce nephrotoxicity. However, whether NPs induce renal fibrosis remains contentious, and the reversibility of NPs-triggered nephrotoxicity has rarely been reported. This study investigated the role of lysosomes in renal fibrosis induced by low-level polystyrene (PS) NPs with particle sizes of 100 and 500 nm (PS100 and PS500) in mice using Masson staining, immunohistochemistry, Western blotting, fluorescence imaging, and other techniques. The results showed that PS100 induced more pronounced renal fibrosis than PS500. Mechanistically, PS NPs promoted autophagosome formation accompanied by the inhibition of autophagic degradation. Moreover, PS NPs impaired lysosomal degradation function, evidenced by reduced CTSB and CTSD protein levels. This impairment blocked autophagic flux, thereby inducing renal fibrosis, which was further confirmed by in vitro results. Notably, lysosomal exocytosis plays a crucial role in the clearance of NPs from mouse kidneys through activating Mcoln1 expression, which contributes to restoring autophagic flux and alleviating renal fibrosis during recovery. Collectively, our findings provide the first evidence that lysosomes serve dual functions in the persistence and reversibility of NPs-induced nephrotoxicity, which could be valuable for the intervention and mitigation of kidney damage resulting from environmental NPs exposure.\n\nID: 40607257\nTitle: Polystyrene Nanoplastics Exacerbate HFD-induced MASLD by Reducing Cathepsin Activity and Triggering Large Vacuole Formation via Impaired Lysosomal Acidification.\nAbstract: Environmental nanoplastics (NPs) have harmful effects on health. This study investigated the effects of polystyrene (PS) NPs on steatosis and fatty liver disease. PS-NP oral administration, in conjunction with a high-fat diet (HFD), synergistically exacerbated the symptoms of steatosis in mice, leading to increased alanine transaminase, aspartate aminotransferase, and cholesterol levels; no effects were observed with PS-NPs on a normal chow diet. Transcriptome analysis unveiled that PS-NPs interfered with actin organization, cell-cell adhesion, PPAR signaling, and lipid metabolism. In HepaRG cells, PS-NPs rapidly entered by inducing actin rearrangement, resulting in the formation of numerous small cytoplasmic vesicles. This treatment led to an augmented number of acidic organelles, leading to development and buildup of large vacuoles, indicative of enlarged pre-lysosomal and lysosomal compartments. PS-NP exposure hampered p62 degradation, leading to LC3B accumulation and decreased cathepsin B and D activity. Additionally, PS-NP exposure resulted in accumulation of lipid droplets and elevated expression of lipogenesis-, transport-, and storage-related genes. These findings suggest that excessive endocytosis driven by PS-NPs worsens MASLD in HFD through accumulation of lysosomes and large vacuoles with reduced cathepsin activity.\n\nID: 40540868\nTitle: Aggregation and deposition kinetics of polystyrene nanoplastics in lung fluids: Influence of particle property, fluid condition, and surfactant protein.\nAbstract: Nanoplastics (NPs) are emerging atmospheric contaminants that aggregate and deposit in lung fluids post-inhalation, affecting their migration and health risks. This study investigated the aggregation and deposition kinetics of six polystyrene NPs (PSNPs): NP50, NP100, NP500, A-NP50 and A-NP100 (amino-modified), and C-NP100 (carboxyl-modified), in artificial lysosomal fluid (ALF) and Gamble's solution (GMB). In ALF, PSNPs aggregated within 20\u202fmin to 132-1066\u202fnm, with rates ranking A-NP50\u202f>\u202fNP100\u202f>\u202fA-NP100\u202f>\u202fC-NP100\u202f>\u202fNP50\u202f>\u202fNP500. After 24\u202fh, most exceeded 5000\u202fnm, except NP500 (1473\u202fnm). In GMB, only positively charged A-NP50 aggregated substantially (> 5000\u202fnm), while negatively charged PSNPs remained stable. All PSNPs exhibited higher deposition rates in ALF than GMB. Higher particle concentrations promoted aggregation for all PSNPs in ALF, but only A-NP50 in GMB. Opposite pH effects on A-NP50 and NP50 were observed. Na2HPO4, NaHCO3, sodium pyruvate, and trisodium citrate promoted A-NP50 aggregation via electrostatic interactions and adsorption. BSA modulated aggregation in a concentration- and fluid-dependent manner: low levels (< 260\u202fmg/L) enhanced NP50 aggregation via charge screening, while higher levels stabilized it via steric hindrance. For A-NP50, BSA consistently reduced aggregation. These findings provide insights into NP transport and health risks in pulmonary environments.\n\nID: 40527086\nTitle: Modulating tumor acidity with hydroxyethyl starch-based nanoparticles by targeting CA9 to eliminate cancer stem cells and overcome immunosuppression.\nAbstract: The acidic microenvironment in solid tumors, primarily driven by Warburg effect, promotes tumor progression, immune evasion, and resistance to therapy. Cancer stem cells (CSCs), a critical subset within tumor tissues, exacerbate this acidity through overexpression of pH-regulating proteins such as carbonic anhydrase IX (CA9), which plays a pivotal role in maintaining pH homeostasis, contributes to immune suppression, and sustains CSC stemness and proliferation. In this study, we designed CA9 inhibitor (CAi) coupled hydroxyethyl starch-based nanoparticles (CHHD-Cu NPs) that integrate doxorubicin (DOX) mediated chemotherapy with copper ions (Cu2+) mediated chemodynamic therapy to target and eliminate CA9-expressing CSCs. Upon administration, CHHD-Cu NPs bind to CA9 and disrupt pH regulation, thereby lowering intracellular pH and raising extracellular pH. This pH modulation enhances intracellular releases of DOX and Cu2+ and alleviates extracellular acidity to boost effector T cells infiltration and activity. Our rationally designed CHHD-Cu NPs eliminate CSCs in two ways: firstly, by robust intracellular DOX- and copper-induced cytotoxicity, and secondly, via pH modulation-mediated activation of anti-tumor immunity. Our strategy offers novel approaches for treatment of immunosuppressive solid tumors.\n\nID: 40474178\nTitle: Polystyrene nanoplastics trigger pyroptosis in dopaminergic neurons through TSC2/TFEB-mediated disruption of autophagosome-lysosome fusion in Parkinson's disease.\nAbstract: Parkinson's disease (PD) is a sporadic neurodegenerative disorder with a rising incidence. Environmental toxins are considered the main etiological factor. The increasing use of polystyrene nanoparticles (PS-NPs) has raised concerns about their potential neurotoxic effects in PD. This study aimed to investigate the impact of PS-NPs on the onset and progression of PD and the underlying mechanisms. The breach of the blood-brain barrier (BBB) by PS-NPs was assessed using bioluminescence imaging, fluorescence observation, Pyrolysis-Gas Chromatography-Mass Spectrometry (Py-GCMs), transmission electron microscope (TEM), and Evans blue staining. To evaluate the potential promotion of PD by PS-NPs, a 30-day repeated oral administration study was conducted in vivo, during which behavioral changes and alterations in dopaminergic neurons in the substantia nigra were assessed. In vitro cytotoxicity assays were performed following PS-NPs intervention. Molecular biology techniques, including Western blotting and immunofluorescence, were employed to analyze proteins related to pyroptosis and autophagy-lysosomal pathway in both in vivo and in vitro settings. Additionally, proteomic sequencing was utilized to identify the upstream regulator of the autophagy-lysosomal pathway (ALP), and the effects of modulating this target protein on the ALP-pyroptosis pathway were analyzed. Bioluminescence imaging and Py-GCMs confirmed that PS-NPs entered the brain within 1.5\u00a0h. Evans blue staining and TEM showed PS-NPs damaged the BBB. The 30-day oral toxicity revealed that PS-NPs exacerbated behavioral abnormalities and caused dopaminergic neuron loss. Western blotting and immunofluorescence indicated that PS-NPs induced pyroptosis, disrupted autophagic flux, and lowered protein levels involved in autophagosome-lysosome fusion, both in vivo and in vitro. Furthermore, PS-NPs activated the mechanistic target of rapamycin (mTOR) and inhibited the nuclear translocation of Transcription Factor EB (TFEB). Proteomic sequencing identified a deficit of Tuberous Sclerosis Complex (TSC) 2 protein within the mTOR pathway. Immuno-coprecipitation and Coomassie Blue Fast Staining revealed that PS-NPs bound to TSC2 protein, causing disassembly of TSC1-TSC2 complex. These findings underscore how PS-NPs accelerated PD onset and progression by disrupting autophagosome-lysosome fusion through TSC2-mTOR-TFEB axis, which triggered protein degradation disorders and pyroptosis in dopaminergic neurons. The molecular mechanisms could inform environmental safety regulations concerning nanoplastics and inspire therapeutic strategies for PD.\n\nID: 40456013\nTitle: From Nanoparticles to Single Crystals of Al-MOFs: Synergistic Coordination and pH Modulation, and Rapid Sorption Kinetics Assessment by Optical Calorimetry.\nAbstract: The properties of metal-organic frameworks (MOFs), such as sorption kinetics or mechanical and chemical stability, not only depend on their composition and chemical structure, but also on their crystal size and morphology. However, the tunability of the crystallite size of aluminum-based MOFs (Al-MOFs) is still a long-standing challenge. In this study, we present systematic high-throughput investigations elucidating the synergistic effects of different mono- and dicarboxylic acids (acetic acid, malonic acid, and oxalic acid) as coordination modulators and NaOH as a pH modulator on the crystal size of various Al-MOFs, with a focus on Al-MIL-53-NO2. By varying the type and amount of coordination modulators, we successfully extended the range of achievable particle sizes to nanoparticles as well as large crystals (dmax\u00a0\u2248\u00a0100\u00a0nm\u00a0-\u00a0800\u00a0\u00b5m) compared to traditional synthesis methods using only coordination modulators. Thus, large crystals as well as nanoparticles of different Al-MOFs could be obtained by simply varying the molar ratio of the different modulators. Additionally, we explored the influence of particle size on CO2 sorption properties using InfraSORP technology (optical calorimetry), revealing the increase in adsorption rates with decreasing particle size.\n\nID: 40413758\nTitle: Defective autophagy in a fibroin secretion-deficient silkworm mutant.\nAbstract: The silkworm Bombyx mori is an economically important insect for silk production. Its silk glands are responsible for the synthesis and secretion of silk proteins. The naked pupa (Nd), a fibroin heavy chain mutant strain of silkworm, was found to exhibit severe atrophy, degeneration of the posterior silk gland (PSG), and abnormal secretion of fibroin proteins, thereby producing little or no silk. Here, we found that the autophagic marker Atg8-PE was upregulated through the target of rapamycin complex 1 signaling pathway in Nd. However, as autophagy substrates, SQSTM1/p62 and ubiquitinated protein levels increased in Nd. Furthermore, treatment with BafA1 showed no effect on the protein levels of SQSTM1/p62, indicating impaired autophagic flux in Nd. Abnormal acidification of lysosomes was further detected, which resulted in a decreased proportion of matured CtsL1 (cathepsin L1). Thus, the substrate in autolysosomes cannot be degraded within a rapid time frame, resulting in the accumulation of protein aggregates, which cause atrophy and degeneration of the PSG. We also found that acidic nanoparticles rescued lysosomal acidification and relieved the degenerative changes of Nd-PSG. The findings of this study suggest that the Nd mutant silkworm can be used as an animal model for studying protein aggregation diseases.Abbreviations: AD: Alzheimer disease; aNP: acidic nanoparticle; APP: amyloid beta precursor protein; Atg8: autophagy related 8; BACE1: beta-secretase 1; BafA1: bafilomycin A1; CtsL1: cathepsin L1; CRY: crystallin; ER: endoplasmic reticulum; FibH: fibroin heavy chain; FibL: fibroin light chain; FUS: FUS RNA binding protein; HD: Huntington disease; HRP: horseradish peroxidase; Nd: naked pupa; OSBPL2: oxysterol binding protein like 2; PD: Parkinson disease; PE: phosphatidylethanolamine; p-EIF4EBP: phosphorylated eukaryotic initiation factor 4E binding protein; PROM1: prominin 1; p-RPS6KB: phosphorylated ribosomal protein S6 kinase B; PSEN: presenilin; PSG: posterior silk gland; SDS-PAGE: sodium dodecyl sulfate-polyacrylamide gel electrophoresis; SEM: standard error of the mean; SOD1: superoxide dismutase 1; SQSTM1/p62: sequestosome 1; TARDBP: TAR DNA binding protein; TORC1: target of rapamycin complex 1; UBQLN2: ubiquilin 2; V-ATPase: vacuolar-type ATPase.\n\nID: 42456394\nTitle: Defective lysosomal acidification promotes chondrocyte senescence and autophagic flux stagnation in geriatric osteoarthritis.\nAbstract: Geriatric osteoarthritis (G-OA) represents a senescence and metabolism-driven pathobiological phenotype, closely associated with ageing. Although lysosomal dysfunction is increasingly recognized as a cardinal feature of age-related diseases, most current therapeutic strategies primarily target upstream regulators of autophagy, particularly the PI3K/AKT/mTOR pathway. However, this approach may be limited in aged chondrocytes, where the efficiency of autophagic degradation is already compromised. With ageing, reduced vacuolar ATPase activity and the accumulation of intralysosomal lipofuscin may impair lysosomal acidification and degradative capacity. As a result, even when autophagy is pharmacologically stimulated, the clearance of autophagic cargo remains inefficient. This imbalance leads to the accumulation of undegraded autophagosomes, contributing to cellular stress and impaired autophagic flux. Importantly, lysosomal dysfunction under these conditions has increasingly been associated with the amplification of the senescence-associated secretory phenotype (SASP), activation of the NLRP3 inflammasome, and subsequent macrophage dysregulation. These interconnected processes may further exacerbate joint degeneration in G-OA. This review identifies lysosomal restoration as a potential therapeutic intervention point for overcoming downstream autophagic impairment in G-OA. Enhancing lysosomal acidification and degradative function may help re-establish effective autophagic flux and improve disease outcomes. Although several components of this proposed mechanistic framework require direct experimental validation in aged chondrocytes, the model provides a biologically plausible and testable basis for future investigations into lysosome-targeted therapeutic strategies for G-OA.\n\nID: 42415176\nTitle: Zinc-mediated lysosomal activation by 1H10 enhances autophagy and attenuates tau pathology in Alzheimer's disease models.\nAbstract: Impaired autophagic flux and lysosomal dysfunction contribute critically to the accumulation of pathological protein aggregates in Alzheimer's disease (AD). Emerging evidence suggests that intracellular zinc dynamics regulate lysosomal function by modulating processes such as acidification and lysosomal biogenesis. We previously identified 1H10 as an AMP-activated protein kinase (AMPK) inhibitor and subsequently demonstrated its zinc-binding capacity and ability to regulate intracellular zinc homeostasis. Building on our prior findings that intra-lysosomal zinc promotes acidification and activates transcription factor EB (TFEB), we investigated whether 1H10 enhances lysosomal function through zinc mobilization in neurons, thereby improving autophagy and reducing pathological protein accumulation. In primary cortical neurons, 1H10 increased lysosomal abundance and enhanced lysosomal degradative capacity in a zinc-dependent manner, as demonstrated by increased cathepsin B activity and DQ-BSA degradation. It alleviated lysosomal dysfunction induced by v-ATPase inhibition and promoted autophagic flux, leading to reduced accumulation of amyloid-\u03b2 (A\u03b2) and tau in neuronal models. In 5XFAD mice, 1H10 treatment showed trends toward improved spatial learning in the Morris water maze, reduced tau phosphorylation at Thr205 and Ser214, normalized LC3-II levels, and restored autophagic-lysosomal homeostasis, without significant changes in extracellular amyloid plaque burden. These findings indicate that zinc-mediated lysosomal activation by 1H10 enhances the autophagy-lysosomal pathway and attenuates tau pathology in AD models, suggesting that targeting lysosomal function may represent a potential therapeutic strategy for neurodegenerative disorders characterized by impaired proteostasis.\n\nID: 42309187\nTitle: Human blood-derived neural progenitor cells as a platform for developmental neurotoxicity of micro- and nanoplastics.\nAbstract: Micro- and nanoplastics (MNPs) are increasingly detected in human tissues, including the placenta and brain, raising concerns about their potential impact on early neurodevelopment. However, mechanistic insight is limited by the lack of human-relevant, scalable test systems for developmental neurotoxicity (DNT). Here, we establish and apply a peripheral blood-derived human neural progenitor cell (NPC) platform as a reproducible in vitro model to evaluate MNP-induced DNT under low-dose conditions reflecting currently available estimates of human exposure. Using this system, we systematically investigated the effects of 2\u202f\u00b5m, 100\u202fnm, and 20\u202fnm polystyrene particles and polyester microfibers over a 21-day neuronal differentiation paradigm. The model enables simultaneous assessment of key DNT endpoints, including neuronal differentiation, neurite outgrowth, cell cycle progression, and oxidative stress. MNP exposure impaired neuronal maturation in a size- and shape-dependent manner, reducing neurite outgrowth and \u03b2III-tubulin (TUJ1) expression. Nanoscale particles were efficiently internalized and localized to endo-lysosomal compartments, whereas micron-sized particles remained primarily surface-associated. Mechanistically, MNP exposure induced mitochondrial oxidative stress, decreased superoxide dismutase 2 expression, and disrupted cell cycle exit, resulting in sustained progenitor proliferation. Importantly, pharmacological scavenging of reactive oxygen species with N-acetyl-L-cysteine rescued differentiation deficits and normalized cell cycle dynamics, demonstrating a causal role for redox imbalance. Together, these findings validate peripheral blood-derived human NPCs as a sensitive and scalable platform for DNT assessment and provide mechanistic evidence that MNPs impair early human neurodevelopment through size-dependent uptake and oxidative stress pathways.\n\nID: 42155397\nTitle: Avian pathogenic Escherichia coli virulence protein Hcp2a induces incomplete autophagy in chicken HD11 cells.\nAbstract: The hemolysin co-regulator protein (Hcp) is a core virulence protein of the Type VI Secretion System (T6SS) in avian pathogenic Escherichia coli (APEC) and plays a critical role in host-pathogen interactions. While several bacterial effectors are known to subvert host immunity by modulating autophagy, whether and how the APEC Hcp2a protein influences autophagy in chicken macrophages (HD11) remains unclear. Here, we demonstrate that Hcp2a is efficiently internalized into HD11 cells and induces significant cytotoxicity. Notably, Hcp2a treatment elicited an autophagic response, as evidenced by elevated LC3-II levels and increased formation of autophagic vesicles. However, this was accompanied by p62/SQSTM1 aggregation and impaired autophagic flux, indicating a blockade in autophagosome-lysosome degradation. Quantitative proteomic analysis revealed significant down-regulation of the lysosomal pathway, particularly of key components involved in acidification and proteolysis. Functional assays confirmed that Hcp2a causes lysosomal dysfunction, characterized by the reduction in acidic lysosomal compartments and decreased levels of mature cathepsin D (CTSD). These defects ultimately impair the degradative capacity of lysosomes following autophagosome fusion, culminating in the block of autophagic flux. Our findings uncover a mechanism by which APEC Hcp2a interrupts host autophagy through lysosomal impairment, providing novel insights into APEC pathogenesis and bacterial immune evasion strategies.\n\nID: 42093145\nTitle: When tau stalls the lysosome: decoupling trafficking and degradation in autophagy.\nAbstract: Tauopathies are characterized by the accumulation of misfolded tau and lysosomal dysfunction, yet whether defects in the autophagy-lysosome pathway are causal or secondary remains unclear. Recent work using human iPSC-derived neurons harboring the MAPT p.R406W mutation demonstrates that pathogenic tau is sufficient to disrupt lysosomal function upstream of tau accumulation. Tau species are differentially processed within lysosomes, with phosphorylated tau retained at the lysosomal membrane, consistent with a barrier to efficient cargo processing. Importantly, pharmacologic activation of autophagy restores degradative capacity and reduces tau burden without rescuing lysosomal motility, suggesting that trafficking and degradation represent separable axes of lysosomal biology. These findings position tau as an active disruptor of proteostasis and define a degradative bottleneck that shares features with lysosomal storage disorders. Together, this work reframes autophagy dysfunction in tauopathy as a modular defect with distinct therapeutic entry points.\n\nID: 41993776\nTitle: Autophagy-Modulated Sonodynamic Therapy Triggers Mitochondrial Catastrophe for Potent Immunogenic Tumor Eradication.\nAbstract: Sonodynamic immunotherapy represents a promising strategy for cervical cancer treatment by stimulating antitumor immune responses. However, therapy-induced prosurvival autophagy may attenuate therapeutic efficacy. To address this limitation, we constructed multifunctional nanoparticles (poly[lactic-co-glycolic acid]-b-poly[ethylene glycol] [PLGA-PEG2,000]-based nanoparticles coloaded with hematoporphyrin monomethyl ether and SAR405 [PHS NPs]) codelivering the sonosensitizer hematoporphyrin monomethyl ether and the selective vacuolar protein sorting 34 inhibitor SAR405. Upon low-intensity focused ultrasound irradiation, PHS NPs generated reactive oxygen species that induced mitochondrial stress while concurrently modulating autophagic flux through VPS34 inhibition. This coordinated intervention was associated with microtubule-associated protein 1A/1B-light chain 3-II and p62 coaccumulation and the presence of undegraded autolysosomal structures, suggesting impairment of lysosome-associated autophagic degradation. Enhanced oxidative stress, together with modulation of autophagic flux, was accompanied by lysosomal dysfunction and reduced degradative capacity. These alterations were associated with sustained intracellular stress and amplified oxidative injury in tumor cells. Functionally, the combined treatment suppressed tumor growth, promoted immunogenic cell death, and was accompanied by macrophage polarization toward an M1-like phenotype and increased CD8+ T cell infiltration. Validated in HPV-associated tumor models, this nanoparticle-based strategy provides a rational and potentially translatable platform to mitigate autophagy-associated adaptive responses and enhance the therapeutic potential of sonodynamic immunotherapy in solid tumors.\n\nID: 41744788\nTitle: The Role of Autophagy-Lysosomal Pathways in Photoreceptor Death in the rd10 Mouse Model of Inherited Retinal Degeneration.\nAbstract: Inherited retinal degenerations, such as retinitis pigmentosa, are a leading cause of irreversible vision loss, yet broadly effective treatments remain elusive. Impaired cellular waste clearance via autophagy-lysosomal pathways have been implicated in photoreceptor death, but the spatiotemporal dynamics of these processes during degeneration remain poorly understood. Using the rd10 mouse model of retinitis pigmentosa, we characterised autophagy-lysosomal dysfunction at key stages of photoreceptor degeneration (postnatal day P17, P22, P35) through super-resolution imaging of RFP-EGFP-LC3 reporter mice, Western blot, and bulk RNA sequencing. Autophagosome and autolysosome numbers were significantly elevated across all photoreceptor compartments (inner/outer segments, outer nuclear layer, outer plexiform layer) at P17, prior to significant photoreceptor nuclei loss. Autophagosome and autolysosome size progressively increased from P22 onwards, suggesting accumulation of unprocessed intracellular waste. Molecular analyses revealed downregulation of mTOR protein, upregulation of autophagy-related genes, and increased lysosomal processes from P17. These histological and molecular findings are consistent with early autophagy induction followed by overwhelmed degradative capacity. Our findings identify autophagy-lysosomal change as an early event in photoreceptor loss in the rd10 model, revealing a critical therapeutic window for mutation-independent interventions targeting cellular clearance pathways in inherited retinal degenerations.\n\nID: 41607468\nTitle: Bidirectional crosstalk between the bone extracellular matrix and lysosomes in bone remodeling and osteoporosis.\nAbstract: Osteoporosis is a systemic skeletal disorder characterized by progressive loss of bone mass and deterioration of microarchitectural integrity. Traditionally, its pathogenesis has been attributed primarily to an imbalance in the number and activity of osteoblasts and osteoclasts. However, emerging evidence has uncovered a critical bidirectional interdependence between the integrity of the extracellular matrix (ECM) and the functional homeostasis of the intracellular lysosomal system-an axis increasingly recognized as the \"bone matrix-lysosome crosstalk.\" Despite its apparent importance, the central role of this regulatory circuitry in bone homeostasis and the mechanisms through which it becomes disrupted under pathological conditions remain insufficiently defined.This review synthesizes current advances regarding the cell type-specific functions of lysosomes across distinct bone cell populations and further examines how the ECM, as a dynamic microenvironment, exerts reciprocal control over lysosomal biogenesis and activity. We highlight how the biochemical composition and biophysical properties of the ECM govern lysosomal acidification, metabolic coupling, and degradative capacity with remarkable precision. During the progression of osteoporosis, structural compromise of the ECM and lysosomal dysfunction reinforce one another, establishing a self-amplifying pathological loop that accelerates the collapse of the bone microenvironment. Recognizing this reciprocal deterioration, we propose that restoring the dynamic equilibrium of the \"ECM-lysosome axis\" may represent a mechanistic pivot for reversing osteoporotic degeneration. Interventions targeting lysosomal function, reconstructing the bone ECM, and employing nanomedicine-enabled organelle-specific delivery hold particular promise for advancing precision therapeutics in osteoporosis.\n\nID: 41575856\nTitle: Polystyrene nanoplastics readily penetrate intestine and cause sex-specific effects mediated by bile acids and microbiome.\nAbstract: Orally ingested nanoplastics can enter the blood flow; however, their digestive tract fate is unclear. We found that \u223c60% of ingested polystyrene nanoparticles (PSNPs) cross the intestine wall in 3 h, but most are captured by the liver and discharged via the biliary system. Nanoparticle-bound bile acids (BAs) and apical sodium-dependent bile acid transporter (ASBT) mediate this fast absorption of PSNPs. In the liver, PSNPs block CYP7A1 degradation by disrupting lysosome biogenesis, which promotes BA synthesis and increases colitis susceptibility of mice by reducing Lactobacillus and increasing Enterobacteriaceae. Significant sexual dimorphism is unexpectedly discovered after PSNP treatment, where male mice are more sensitive than females due to the higher ASBT expression on enterocytes in males. In summary, our results could guide usage of plastic and prompt design of efficient carriers for oral drug delivery as well as indicate that sex should not be ignored both in drug administration and disease.\n\nID: 41373881\nTitle: Polystyrene Nanoplastics in Human Gastrointestinal Models-Cellular and Molecular Mechanisms of Toxicity.\nAbstract: Plastic pollution is a growing environmental and health issue due to the increasing presence of micro- and nanoplastics in terrestrial and aquatic ecosystems. Polystyrene nanoplastics (PS-NPs) are among the most extensively studied because of their wide occurrence, physicochemical stability, and availability for laboratory research. Their nanoscale size enables interaction with biological systems at the molecular level, promoting internalization, intracellular trafficking, and potential bioaccumulation. This review summarizes current knowledge on the cellular effects and molecular mechanisms of PS-NPs, particularly in human gastrointestinal models. The gastrointestinal tract is a primary route of nanoplastic exposure, where PS-NPs can cross epithelial barriers, interact with immune and epithelial cells, and disturb cellular homeostasis. Once internalized, PS-NPs can induce oxidative stress, mitochondrial dysfunction, and dysregulation of autophagy, leading to alterations in lipid and glucose metabolism. Excessive synthesis of reactive oxygen species may trigger DNA damage, activate the ATM/ATR-p53 signaling pathway, and impair DNA repair mechanisms, thereby contributing to genomic instability. Emerging evidence also shows that PS-NPs can interact with ion channels, affecting calcium homeostasis, membrane potential, and cell viability. Overall, these findings highlight the complex and multifaceted toxicity of PS-NPs at the cellular level and underscore the need for further research to assess the long-term risks of nanoplastic exposure.\n\nID: 41331534\nTitle: E3 ligase AREL1 controls perinuclear localization of lysosomes and supports Purkinje cell survival.\nAbstract: Localization of lysosomes influences their properties, e.g., perinuclear lysosomes are more acidic but less mobile compared with the peripheral ones. Furthermore, the endoplasmic reticulum (ER) can actively regulate the dynamics and functions of lysosomes via membrane contact sites. In this study, we find that ER-resident apoptosis-resistant E3 ubiquitin protein ligase 1 (AREL1) establishes membrane contacts with lysosomes by directly interacting with the Voa subunit of V-ATPase. AREL1 also catalyzes K33-linked polyubiquitylation of V-ATPase V1B2 subunit, inducing its binding to UBAC2 localized in the perinuclear ER. Depletion of AREL1 or UBAC2 increases the number of peripheral lysosomes that possess partially assembled V-ATPase, elevated luminal pH, and attenuated degradative capacity. Knockdown of ZRANB1, the deubiquitylating enzyme that antagonizes AREL1-mediated V1B2 ubiquitylation, promotes perinuclear clustering of lysosomes and increases lysosomal acidity and degradation. Mice lacking Arel1 exhibit age-dependent Purkinje cell loss, an ataxic phenotype, and motor impairment. Lipofuscin accumulation in the residual Purkinje cells of Arel1-/- mice indicates lysosomal dysfunction. Orchestration of lysosomal positioning and function by the AREL1-UBAC2-V-ATPase axis underscores the physiological significance of ER-regulated perinuclear lysosomal positioning in neurons.\n\nID: 41026805\nTitle: Expansion of lysosomal capacity in early adult neurons driven by TFEB/HLH-30 protects dendrite maintenance during aging in Caenorhabditis elegans.\nAbstract: Lysosomes are essential for neuronal homeostasis, providing degradation and recycling functions necessary to support neurons' complex operations and long lifespans. However, the regulation of lysosomal degradative capacity in healthy neurons is poorly understood. Here, we investigate the role of HLH-30, the sole Caenorhabditis elegans homolog of Transcription Factor EB (TFEB), a master regulator of lysosome biogenesis and autophagy that is thought to predominantly function in the context of starvation or stress. We demonstrate that HLH-30 is dispensable for neuronal development but acts cell-intrinsically to expand lysosomal degradative capacity during early adulthood. Loss of HLH-30 leads to lysosomal dysfunction and delayed turnover of synaptic vesicle proteins from the synapse. Notably, we show that basal HLH-30 activity is sufficient to expand neuronal lysosomal capacity without nuclear enrichment, in contrast to the nuclear translocation associated with starvation- and stress-induced activation of TFEB and HLH-30. Furthermore, we show that neuronal lysosomal function declines with age in wild-type animals, and this corresponds to a decrease in basal HLH-30-mediated transcription. We further demonstrate that basal HLH-30 activity is crucial for neuron maintenance: lysosomal dysfunction due to inadequate HLH-30 activity leads to dendrite degeneration and aberrant outgrowths. In summary, our study establishes a critical role for HLH-30/TFEB in promoting lysosomal capacity to preserve neuronal homeostasis and structural integrity of mature neurons in vivo.\n\nID: 40806168\nTitle: Biological Modulation of Autophagy by Nanoplastics: A Current Overview.\nAbstract: Nanoplastics (NPs), an emerging class of environmental pollutants, are increasingly recognized for their potential to interfere with critical cellular processes. Autophagy, a conserved degradative pathway essential for maintaining cellular homeostasis and adaptation to stress, has recently become a focal point of nanotoxicology research. This review synthesizes current evidence on the interactions between NPs and autophagic pathways across diverse biological systems. Findings indicate that NPs can trigger autophagy as an early cellular response; however, prolonged exposure may lead to autophagic dysfunction, contributing to impaired cell viability and disrupted signaling. Particular attention is given to the physiochemical properties of NPs such as size, surface charge, and polymer type, which influence cellular uptake and intracellular trafficking. We also highlight key mechanistic pathways, including oxidative stress and mTOR modulation. Notably, most available studies focus almost exclusively on polystyrene (PS)-based NPs, with limited data on other types of polymers, and several reports lack comprehensive assessment of autophagic flux or downstream effects. In conclusion, a better understanding of NP-autophagy crosstalk-particularly beyond PS-is crucial to evaluate the real toxic potential of NPs and guide future research in human health and nanotechnology.\n\nID: 40238681\nTitle: Passing the Parcels: Intercellular Nanoplastics Transfer in Mussels Perna viridis with Activated Immunomodulation.\nAbstract: Nanoplastics (NPs) are generally considered to have a defined intracellular fate, being difficult to excrete or transport due to their stability. This study provides the first evidence of NPs intercellular transfer in the hemocytes of green mussels (Perna viridis), which subsequently activated the immunomodulation process. NPs were predominantly internalized by granulocytes, with a portion being translocated and deposited in lysosomes, whereas those retained in endosomes were subsequently transferred to new hemocytes (mainly granulocytes). The transfer direction was driven by the intracellular NP concentration gradients. Transfer kinetics was size-dependent, with smaller-sized NPs exhibiting greater potential but a lower rate, primarily due to their specific extracellular vesicle-mediated transfer pathway. Tunneling nanotubes provided the most efficient pathway for the intercellular transfer of NPs, as their continuous membrane structure allowed direct substance exchange. Crucially, NP redistribution was accompanied by a gradient-driven transfer of mitochondria to injured hemocytes. This process alleviated stress on the overburdened hemocytes and regulated reactive oxygen species production, subsequently enhancing phagocytic activity and promoting immune responses. These findings underscore that NPs exhibit far more active behavior in the immune system than previously understood and provide new insights into how immune cells maintain the health of marine organisms in the face of NP challenges.\n\nID: 40171975\nTitle: Subchronic Exposure to Polystyrene Nanoplastics Disrupts Placental Development and Calcium Homeostasis: Insights from In Vivo and In Vitro Models.\nAbstract: Nanoplastics have recently emerged as persistent pollutants of global concern that pose substantial risks to human health. However, the long-term adverse effects of nanoplastics on the female reproductive system remain unclear. Polystyrene nanoplastics (PS-NPs; 50 nm diameter) were selected as representative nanosized plastic particles to investigate the potential effects of subchronic prenatal and gestational exposure via drinking water on placental development in ICR (CD-1) mice. Maternal exposure to 10 mg/L PS-NPs induced an increase in fetal resorption rate and significantly increased fetal weight. Further observation of the placental morphology showed that PS-NPs exposure led to an aberrant placental structure and damaged the trophoblast cells. At the cellular level, PS-NPs exposure promoted the proliferation, migration, and invasion of HTR-8/SVneo cells. Mechanistically, transcriptomic and proteomic analyses revealed that PS-NPs triggered placental calcium disturbances and upregulated the Stam2 expression in mice. STAM2 induced by PS-NPs mediates the disruption of trophoblastic calcium homeostasis and regulates cell functions by disturbing the lysosomal degradation of the calcium channel protein IP3R3 and promoting intracellular calcium inflow by increasing the level of TRPV6 in HTR-8/SVneo cells. Therefore, our results indicated that trophoblastic calcium dyshomeostasis is the main mechanism by which subchronic PS-NPs exposure induces abnormal placental development. These findings reveal a link between subchronic PS-NPs exposure and placental damage and elucidate the underlying molecular mechanism, providing evidence for environmental triggers of adverse pregnancy and highlighting the risk of plastic products to pregnant women.\n\nID: 40070069\nTitle: The Role of Glycolipids and their Toxicity in the Context of Nanomaterials and Nanoparticles: A Review of the Literature.\nAbstract: Diseases triggered by glucose and lipid metabolic disorders, such as hyperglycemia and hyperlipidemia, have become a global health threat. According to statistics, diabetic patients have exceeded 463 million worldwide, and the prevalence of hyperlipidemia is also continuously rising. These glycolipid metabolic diseases not only significantly increase the risk of complications such as cardiovascular disease, stroke, and kidney disease but also impose a huge economic burden on the global healthcare system. Despite the continuous emergence of treatment methods for glucose and lipid metabolic diseases with the advancement of research technology, existing therapies still face many challenges. In recent years, the rapid development of nanotechnology has injected new vitality into the medical field. As an emerging research field, nanomedicine has attracted much attention for its application prospects in the treatment of glycolipid metabolic diseases. Nanotechnology is expected to provide more precise and efficient solutions for the treatment of these diseases, thereby reducing global health and economic pressures. The objective of this article is to comprehensively review the relationship between nanotechnology and glucose and lipid metabolism. We have carried out a series of literature searches, focusing on glycolipid effects and toxicity of nano-materials. Nanoparticles as drug carriers or nanoparticles enhance bioavailability and activity. Nano-material-based optical reporters aid in detecting lysosome lipid content, facilitating treatment and drug development for glucose and lipid metabolism disorders. Additionally, nanomaterials find applications in glucose biofuel cells and microalgal lipid metabolism regulation. However, nanomaterials, such as polystyrene nanoplastics, may have toxic effects, inducing macrophage transformation and lipid accumulation in the liver. The development of nanotechnology is still in its infancy, and many disease-based studies are still in the stage of animal experiments and have not yet been applied in clinical practice. However, the universality and multilateralism of the use of nanotechnology give it excellent development prospects and also provide a research direction for medical research.\n\nID: 40065324\nTitle: Lysosomal acidification impairment in astrocyte-mediated neuroinflammation.\nAbstract: Astrocytes are a major cell type in the central nervous system (CNS) that play a key role in regulating homeostatic functions, responding to injuries, and maintaining the blood-brain barrier. Astrocytes also regulate neuronal functions and survival by modulating myelination and degradation of pathological toxic protein aggregates. Astrocytes have recently been proposed to possess both autophagic activity and active phagocytic capability which largely depend on sufficiently acidified lysosomes for complete degradation of cellular cargos. Defective lysosomal acidification in astrocytes impairs their autophagic and phagocytic functions, resulting in the accumulation of cellular debris, excessive myelin and lipids, and toxic protein aggregates, which ultimately contributes to the propagation of neuroinflammation and neurodegenerative pathology. Restoration of lysosomal acidification in impaired astrocytes represent new neuroprotective strategy and therapeutic direction. In this review, we summarize pathogenic factors, including neuroinflammatory signaling, metabolic stressors, myelin and lipid mediated toxicity, and toxic protein aggregates, that contribute to lysosomal acidification impairment and associated autophagic and phagocytic dysfunction in astrocytes. We discuss the role of lysosomal acidification dysfunction in astrocyte-mediated neuroinflammation primarily in the context of neurodegenerative diseases along with other brain injuries. We then highlight re-acidification of impaired lysosomes as a therapeutic strategy to restore autophagic and phagocytic functions as well as lysosomal degradative capacity in astrocytes. We conclude by providing future perspectives on the role of astrocytes as phagocytes and their crosstalk with other CNS cells to impart neurodegenerative or neuroprotective effects.\n\nID: 40037196\nTitle: Exposure of the human placental primary cells to nanoplastics induces cytotoxic effects, an inflammatory response and endocrine disruption.\nAbstract: Humans are inevitably exposed to micro- and nanoplastics (MP/NP). These particles are able to cross the biological barriers and enter the bloodstream with levels close to 1.6\u202f\u00b5g\u202fmL-1; MP/NP have been detected in placentas and meconium of newborns. However, the consequences of this exposure on the integrity, development and functions of the human placenta are not documented. In this study, trophoblasts purified from human placentas at term were exposed for 48\u202fh, to two different sizes of polystyrene nanoparticles (PS-NP) of 20\u202fnm (PS-NP20) and 100\u202fnm (PS-NP100), at environmental and supra-environmental concentrations (0.01-100\u202f\u00b5g\u202fmL-1). Cell viability, oxidative stress, mitochondrial dynamics, lysosomal degradation processes, autophagy, inflammation/oxidative responses and consequences for placental endocrine and angiogenic functions were assessed. PS-NP size determines their internalization rate and their behavior in trophoblasts. Indeed, PS-NP20 are more rapidly translocated, and accumulated in lysosomes as shown by confocal and TEM imaging. They induce higher cytotoxicity than PS-NP100, as early as 1\u202f\u00b5g\u202fmL-1 (p\u202f<\u202f0.05). In addition, they induce a pro-inflammatory cytokines response: IL-1\u00df is induced from 0.01\u202f\u00b5g\u202fmL-1 for the both nanoparticle sizes; IL-6, and TNF-\u03b1 are overexpressed at 100\u202f\u00b5g\u202fmL-1 only for PS-NP20 (p\u202f<\u202f0.05). For the first time, we report that PS-NP disrupt endocrine function, as observed by a decreased hCG release at concentrations found in human blood. This work, provides an in-depth in vitro assessment of the effects of PS-NP on the human placenta.\n\nID: 39883073\nTitle: Polystyrene Nanoplastics Hitch-Hike the Gut-Brain Axis to Exacerbate Parkinson's Pathology.\nAbstract: The neurological implications of micro- and nanoplastic exposure have recently come under scrutiny due to the environmental prevalence of these synthetic materials. Parkinson's disease (PD) is a major neurological disorder clinically characterized by intracellular Lewy-body inclusions and dopaminergic neuronal death. These pathological hallmarks of PD, according to Braak's hypothesis, are mediated by the afferent propagation of \u03b1 synuclein (\u03b1S) via the enteric nervous system, or the so-called gut-brain axis. Here we first examined the effect of enteric exposure to polystyrene nanoplastics on the peripheral and central pathogenesis of A53T, a representative \u03b1S mutant. Specifically, the polystyrene nanoplastics accelerated the amyloid aggregation of A53T \u03b1S, which subsequently elevated the in vitro production of glial activation biomarkers, cytokines, and reactive oxygen species and compromised mitochondrial and lysosomal membrane integrity, further shifting cellular metabolite profiles in association with PD pathophysiology. In vivo, coadministration of the polystyrene nanoplastics and A53T \u03b1S facilitated their synergistic gut-to-brain transmission in mice, leading to progressive impairment of physical and motor skills in resemblance to characteristic PD symptoms. This study provides insights into the response and vulnerability of Parkinson's gut-brain axis to polystyrene nanoplastics.\n\nID: 39853018\nTitle: Polystyrene Nanoplastics Elicit Multiple Responses in Immune Cells of the Eisenia fetida (Savigny, 1826).\nAbstract: The improper disposal of plastic products/wastes can lead to the release of nanoplastics (NPs) into environmental media, especially soil. Nevertheless, their toxicity mechanisms in soil invertebrates remain unclear. This study investigated the impact of polystyrene NPs on Eisenia fetida (Savigny, 1826) immune cells, focusing on oxidative stress, immune responses, apoptosis, and necrosis. Results showed that 100 nm NPs were internalized into the cells, causing cytotoxicity. NPs were observed to inhibit cell viability by increasing reactive oxygen species, decreasing the levels of antioxidants (e.g., superoxide dismutase, catalase, and glutathione), and inducing lipid peroxidation and DNA oxidation. Additionally, assays on neutral red retention time, lysozyme activity, and Ca2\u207a levels demonstrated that NPs resulted in a loss of lysosomal membrane stability and a reduction in immune resistance. The depolarization of the mitochondrial membrane potential and the results of the apoptosis assays confirmed that the NPs induced the onset of early apoptosis. The difficulty of the NP in causing cell death by disrupting the plasma membrane was demonstrated by the results of the lactate dehydrogenase release assays in relation to cell necrosis. This research provides cellular-level insights into the ecological risks of NP exposure on soil fauna.\n\nID: 39740740\nTitle: Nano-sized polystyrene plastics toxicity: Necroptosis pathway caused by autophagy blockade and lysosomal dysfunction.\nAbstract: The persistent detection of nano-sized plastic particles in humans, animals, and animal-derived products underscores the potential impact of these particles on living organisms. Consequently, the toxicology of such particles has emerged as a pivotal research interests in recent years. In this study, NP was synthesized successfully with an average particle size of 100\u00a0nm using a emulsion polymerization method as model particles. Following co-incubation of IEC-6 cells with NP for 24-168\u00a0h, a notable inhibition of cell viability and proliferation was observed. The significant activation of autophagy and a concomitant blockage of autophagic flux in IEC-6 cells after 24-72\u00a0h of co-incubation with NP were unveiled by transmission electron microscopy, western blotting, and double-fluorescent autophagy analysis. A significant increase in the number of lysosomes and an increase in the expression of hydrolase CTSB were detected, indicating dysregulation of lysosomal function. The subsequent transcriptomic and metabolomics analyses, coupled with the observation of activated lysosomes and the RIPK1-RIPK3-MLKL/PYGL pathway, led us to posit that the blockade of autophagy and lysosomal dysfunction, culminating in lysosomal membrane permeabilization (LMP) induced necroptosis, constitutes one of the mechanisms contributing to the cytotoxicity of NP. SYNOPSIS: The cytotoxicity and its related mechanisms of nano-plastic is still unclear. This study found that nano-plastics may induce necroptosis in cells, and autophagy blockade and lysosomal dysfunction are prodromal manifestations.\n\nID: 39321482\nTitle: In vivo bioaccumulation and responses of hemocytes of mussels Perna viridis to microplastics and nanoplastics exposure.\nAbstract: Growing micro- and nano-plastic (MNPs) pollution in the environment poses a threat to marine animals. Due to their excellent filtration capacity, bivalves can easily ingest MNPs, which could be translocated to open circulation system with potential risks. In the present study, the accumulation and elimination of MNPs (200\u00a0nm and 1\u00a0\u00b5m) in the mussel hemolymph serum and hemocytes were firstly quantified, and the differential sensitiveresponses of two subpopulations of hemocytes were then explored by in vivo exposure under environmentally relevant concentration of MNPs (200\u00a0\u00b5g/L). We demonstrated that MNPs were readily translocated into hemolymph serum, but were immediately followed by efficient internalization by hemocytes. Remarkably, concentrations of MNPs in hemolymph were only 0.63 and 0.39 times lower than the ambient exposure concentration. Granulocytes displayed a much higher potential of accumulating MNPs than the agranulocytes. MPs were more readily internalized by granulocytes, with their estimated maximum bioaccumulation factor (BCF) of 0.29\u00a0L/g. Due to the primary function of phagocytic encapsulation of MNPs by granulocytes, lysosome features especially the decline of subsequent lysosome membrane potential could be a potential sensitive biomarker in response to MNPs exposure. Our results provided insights on the bioaccumulation of MNPs at the cellular levels in marine bivalves.\n\nID: 38735599\nTitle: Immunotoxicity of microplastics in fish.\nAbstract: Plastic waste degrades slowly in aquatic environments, transforming into microplastics (MPs) and nanoplastics (NPs), which are subsequently ingested by fish and other aquatic organisms, causing both physical blockages and chemical toxicity. The fish immune system serves as a crucial defense against viruses and pollutants present in water. It is imperative to comprehend the detrimental effects of MPs on the fish immune system and conduct further research on immunological assessments. In this paper, the immune response and immunotoxicity of MPs and its combination with environmental pollutants on fish were reviewed. MPs not only inflict physical harm on the natural defense barriers like fish gills and vital immune organs such as the liver and intestinal tract but also penetrate cells, disrupting intracellular signaling pathways, altering the levels of immune cytokines and gene expression, perturbing immune homeostasis, and ultimately compromising specific immunity. Initially, fish exposed to MPs recruit a significant number of macrophages and T cells while activating lysosomes. Over time, this exposure leads to apoptosis of immune cells, a decline in lysosomal degradation capacity, lysosomal activity, and complement levels. MPs possess a small specific surface area and can efficiently bind with heavy metals, organic pollutants, and viruses, enhancing immune responses. Hence, there is a need for comprehensive studies on the shape, size, additives released from MPs, along with their immunotoxic effects and mechanisms in conjunction with other pollutants and viruses. These studies aim to solidify existing knowledge and delineate future research directions concerning the immunotoxicity of MPs on fish, which has implications for human health.\n\nID: 38267572\nTitle: TFEB and TFE3 cooperate in regulating inorganic arsenic-induced autophagy-lysosome impairment and immuno-dysfunction in primary dendritic cells.\nAbstract: Arsenic (As) is a prevalent and hazardous environmental toxicant associated with cancer and various health problems, which has been shown suppressive effects on dendritic cells (DCs). Autophagy is essential for the innate and adaptive immune responses of DCs, and the transcription factors TFEB and TFE3 are key regulators of autophagic and lysosomal target genes. However, the detrimental alterations of the autophagy-lysosome pathway in As-exposed DCs and the possible coordinating roles of TFEB and TFE3 in the immune dysfunction of this cell are less understood. In this paper, we found that As exposure significantly impaired lysosomal number, lysosomal acidic environment, and lysosomal membrane permeabilization, which might lead to blocked autophagic flux in cultured DCs. Furthermore, our results confirmed that TFEB or TFE3 knockdown exacerbated the disorders of lysosome and the blockade of autophagic flux in As-exposed DCs, and also enhanced the inhibitory expression of co-stimulatory molecules Cd80 and Cd83; adhesion molecule Icam1; cytokines TNF-\u03b1, IL-1\u03b2, and IL-6; chemokine receptor Ccr7; and antigen-presenting molecules MHC II and MHC I. By contrast, overexpression of TFEB or TFE3 partially alleviated the above-mentioned impairment of DCs by inorganic As exposure. In conclusion, these findings reveal a previously unappreciated inhibition of lysosome-mediated degradation and damage of lysosomal membrane integrity leading to dysregulated autophagy and impaired immune functions of DCs by arsenicals, and also suggest TFEB and TFE3 as potential therapeutic targets for ameliorating As toxicity.\n\nID: 37251378\nTitle: The internal dose makes the poison: higher internalization of polystyrene particles induce increased perturbation of macrophages.\nAbstract: Plastics are emerging pollutants of great concern. Macroplastics released in the environment degrade into microplastics and nanoplastics. Because of their small size, these micro and nano plastic particles can enter the food chain and contaminate humans with still unknown biological effects. Plastics being particulate pollutants, they are handled in the human body by scavenger cells such as macrophages, which are important players in the innate immune system. Using polystyrene as a model of micro and nanoplastics, with size ranging from under 100 nm to 6 microns, we have showed that although non-toxic, polystyrene nano and microbeads alter the normal functioning of macrophages in a size and dose-dependent manner. Alterations in the oxidative stress, lysosomal and mitochondrial functions were detected, as well as changes in the expression of various surface markers involved in the immune response such as CD11a/b, CD18, CD86, PD-L1, or CD204. For each beads size tested, the alterations were more pronounced for the cell subpopulation that had internalized the highest number of beads. Across beads sizes, the alterations were more pronounced for beads in the supra-micron range than for beads in the sub-micron range. Overall, this means that internalization of high doses of polystyrene favors the emergence of subpopulations of macrophages with an altered phenotype, which may not only be less efficient in their functions but also alter the fine balance of the innate immune system.\n\nID: 36718947\nTitle: Antiretroviral treatment reveals a novel role for lysosomes in oligodendrocyte maturation.\nAbstract: White matter deficits are a common neuropathologic finding in neurologic disorders, including HIV-associated neurocognitive disorders (HAND). In HAND, the persistence of white matter alterations despite suppressive antiretroviral (ARV) therapy suggests that ARVs may be directly contributing to these impairments. Here, we report that a frontline ARV, bictegravir (BIC), significantly attenuates remyelination following cuprizone-mediated demyelination, a model that recapitulates acute demyelination, but has no impact on already formed mature myelin. Mechanistic studies utilizing primary rat oligodendrocyte precursor cells (OPCs) revealed that treatment with BIC leads to significant decrease in mature oligodendrocytes accompanied by lysosomal deacidification and impairment of lysosomal degradative capacity with no alterations in lysosomal membrane permeability or total lysosome number. Activation of the endolysosomal cation channel TRPML1 prevents both lysosomal deacidification and impairment of oligodendrocyte differentiation by BIC. Lastly, we show that deacidification of lysosomes by compounds that raise lysosomal pH is sufficient to prevent maturation of oligodendrocytes. Overall, this study has uncovered a critical role for lysosomal acidification in modulating oligodendrocyte function and has implications for neurologic diseases characterized by lysosomal dysfunction and white matter abnormalities.\n\nID: 35982578\nTitle: Use of acidic nanoparticles to rescue macrophage lysosomal dysfunction in atherosclerosis.\nAbstract: Dysfunction in the macrophage lysosomal system including reduced acidity and diminished degradative capacity is a hallmark of atherosclerosis, leading to blunted clearance of excess cellular debris and lipids in plaques and contributing to lesion progression. Devising strategies to rescue this macrophage lysosomal dysfunction is a novel therapeutic measure. Nanoparticles have emerged as an effective platform to both target specific tissues and serve as drug delivery vehicles. In most cases, administered nanoparticles are taken up non-selectively by the mononuclear phagocyte system including monocytes/macrophages leading to the undesirable degradation of cargo in lysosomes. We took advantage of this default route to target macrophage lysosomes to rectify their acidity in disease states such as atherosclerosis. Herein, we develop and test two commonly used acidic nanoparticles, poly-lactide-co-glycolic acid (PLGA) and polylactic acid (PLA), both in vitro and in vivo. Our results in cultured macrophages indicate that the PLGA-based nanoparticles are the most effective at trafficking to and enhancing acidification of lysosomes. PLGA nanoparticles also provide functional benefits including enhanced lysosomal degradation, promotion of macroautophagy/autophagy and protein aggregate removal, and reduced apoptosis and inflammasome activation. We demonstrate the utility of this system in vivo, showing nanoparticle accumulation in, and lysosomal acidification of, macrophages in atherosclerotic plaques. Long-term administration of PLGA nanoparticles results in significant reductions in surrogates of plaque complexity with reduced apoptosis, necrotic core formation, and cytotoxic protein aggregates and increased fibrous cap formation. Taken together, our data support the use of acidic nanoparticles to rescue macrophage lysosomal dysfunction in the treatment of atherosclerosis.Abbreviations: BCA: brachiocephalic arteries; FACS: fluorescence activated cell sorting; FITC: fluorescein-5-isothiocyanatel; IL1B: interleukin 1 beta; LAMP: lysosomal associated membrane protein; LIPA/LAL: lipase A, lysosomal acid type; LSDs: lysosomal storage disorders; MAP1LC3/LC3: microtubule associated protein 1 light chain 3; MFI: mean fluorescence intensity; MPS: mononuclear phagocyte system; PEGHDE: polyethylene glycol hexadecyl ether; PLA: polylactic acid; PLGA: poly-lactide-co-glycolic acid; SQSTM1/p62: sequestosome 1.\n\nID: 34528688\nTitle: Cholesteryl hemiazelate causes lysosome dysfunction impacting vascular smooth muscle cell homeostasis.\nAbstract: In atherosclerotic lesions, vascular smooth muscle cells (VSMCs) represent half of the foam cell population, which is characterized by an aberrant accumulation of undigested lipids within lysosomes. Loss of lysosome function impacts VSMC homeostasis and disease progression. Understanding the molecular mechanisms underlying lysosome dysfunction in these cells is, therefore, crucial. We identify cholesteryl hemiazelate (ChA), a stable oxidation end-product of cholesteryl-polyunsaturated fatty acid esters, as an inducer of lysosome malfunction in VSMCs. ChA-treated VSMCs acquire a foam-cell-like phenotype, characterized by enlarged lysosomes full of ChA and neutral lipids. The lysosomes are perinuclear and exhibit degradative capacity and cargo exit defects. Lysosome luminal pH is also altered. Even though the transcriptional response machinery and autophagy are not activated by ChA, the addition of recombinant lysosomal acid lipase (LAL) is able to rescue lysosome dysfunction. ChA significantly affects VSMC proliferation and migration, impacting atherosclerosis. In summary, this work shows that ChA is sufficient to induce lysosomal dysfunction in VSMCs, that, in ChA-treated VSMCs, neither lysosome biogenesis nor autophagy are triggered, and, finally, that recombinant LAL can be a therapeutic approach for lysosomal dysfunction.\n\nID: 34217793\nTitle: Polystyrene nanoplastics dysregulate lipid metabolism in murine macrophages in vitro.\nAbstract: Micro and nanoplastics are one of the major emerging environmental contaminants. Their impact on human health is less explored. There are several in vitro studies on their cellular uptake and accumulation, where micro and nanoplastics were mostly reported to be non-cytotoxic. The effects caused by the direct contact of nanoplastics with the immune system, especially at the cellular level is less known. Here we report that RAW 264.7 macrophages undergo differentiation into lipid laden foam cells when exposed to polystyrene nanoplastics (50 \u03bcg/mL). We found that exposure of RAW 264.7 macrophages to sulfate-modified polystyrene nanoplastics results in the accumulation of lipid droplets in the cytoplasm leading to foam cell formation. Exposure to high concentration of polystyrene nanoplastics (100 and 200 \u03bcg/mL) results in increased reactive oxygen species and impair lysosomes in macrophages. The exposure of BV2 microglial cells to polystyrene nanoplastics (50 \u03bcg/mL) induces lipid accumulation. In addition, our results indicate the role of polystyrene nanoplastics in altering the lipid metabolism in murine macrophages in vitro. In the present study we reported that polystyrene nanoplastics stabilized with anionic surfactants can be potent stimuli for lipotoxicity and foam cell formation leading to the pathogenesis of atherosclerosis posing major threat for animal and human health.\n\nID: 38830624\nTitle: Acidic Nanoparticles Restore Lysosomal Acidification and Rescue Metabolic Dysfunction in Pancreatic \u03b2-Cells under Lipotoxic Conditions.\nAbstract: Type 2 diabetes (T2D), a prevalent metabolic disorder lacking effective treatments, is associated with lysosomal acidification dysfunction, as well as autophagic and mitochondrial impairments. Here, we report a series of biodegradable poly(butylene tetrafluorosuccinate-co-succinate) polyesters, comprising a 1,4-butanediol linker and varying ratios of tetrafluorosuccinic acid (TFSA) and succinic acid as components, to engineer lysosome-acidifying nanoparticles (NPs). The synthesized NPs are spherical with diameters of \u2248100 nm and have low polydispersity and good stability. Notably, TFSA NPs, which are composed entirely of TFSA, exhibit the strongest degradation capability and superior acidifying properties. We further reveal significant downregulation of lysosomal vacuolar (H+)-ATPase subunits, which are responsible for maintaining lysosomal acidification, in human T2D pancreatic islets, INS-1 \u03b2-cells under chronic lipotoxic conditions, and pancreatic tissues of high-fat-diet (HFD) mice. Treatment with TFSA NPs restores lysosomal acidification, autophagic function, and mitochondrial activity, thereby improving the pancreatic function in INS-1 cells and HFD mice with lipid overload. Importantly, the administration of TFSA NPs to HFD mice reduces insulin resistance and improves glucose clearance. These findings highlight the therapeutic potential of lysosome-acidifying TFSA NPs for T2D.\n\nID: 37142604\nTitle: Restoration of lysosomal acidification rescues autophagy and metabolic dysfunction in non-alcoholic fatty liver disease.\nAbstract: Non-alcoholic fatty liver disease (NAFLD) is the most common liver disease in the world. High levels of free fatty acids in the liver impair hepatic lysosomal acidification and reduce autophagic flux. We investigate whether restoration of lysosomal function in NAFLD recovers autophagic flux, mitochondrial function, and insulin sensitivity. Here, we report the synthesis of novel biodegradable acid-activated acidifying nanoparticles (acNPs) as a lysosome targeting treatment to restore lysosomal acidity and autophagy. The acNPs, composed of fluorinated polyesters, remain inactive at plasma pH, and only become activated in lysosomes after endocytosis. Specifically, they degrade at pH of ~6 characteristic of dysfunctional lysosomes, to further acidify and enhance the function of lysosomes. In established in vivo high fat diet mouse models of NAFLD, re-acidification of lysosomes via acNP treatment restores autophagy and mitochondria function to lean, healthy levels. This restoration, concurrent with reversal of fasting hyperglycemia and hepatic steatosis, indicates the potential use of acNPs as a first-in-kind therapeutic for NAFLD.\n=======================================================\n\n### [CUSTOM DATAPOINTS]\nCRITICAL EXTRACTION DIRECTIVE: You MUST extract the following custom datapoints as root-level key/value pairs inside your final JSON block:\n- \"suggested_experiments\": generate 1-3 suggested experiments\n- \"suggested_studies\": generate 1-3 suggested studies\n- \"swansons_literature_based_discovery_candidates\": You are an advanced Literature-Based Discovery (LBD) system executing Swanson\u2019s complementary-but-disjoint (A-B-C) model.

Tris(2-butoxyethyl) phosphate (TBOEP) is a representative organophosphate ester that is widely detected in environmental matrices and human tissues, yet whether chronic exposure to environmentally relevant concentrations of TBOEP drives progressive neurodegenerative pathology remains unclear. Here, using Caenorhabditis elegans as a model organism, we performed a 20-day, time-resolved life-cycle exposure to environmentally relevant concentrations of TBOEP (50-5000\u202fng/L) to systematically assess chronic neurotoxicity. TBOEP exposure induced progressive, age-dependent neurodegenerative phenotypes. Early effects were characterized by selective impairment of locomotor performance starting at 50\u202fng/L, followed by broader systemic toxicity, including growth retardation, feeding deficits, and accelerated aging. Consistent with a Parkinson's disease-like trajectory, hallmark pathological features progressively worsened with exposure duration, including dopamine-dependent functional impairment, while \u03b1-synuclein aggregation and dopaminergic neuronal impairment were mainly observed at concentrations \u2265\u202f500\u202fng/L. Mechanistically, time-resolved transcriptomics identified the lysosomal pathway as a central target of TBOEP. Functional assays further confirmed that TBOEP significantly impaired lysosomal acidification. Pharmacological validation with the lysosomal chaperone ambroxol showed that improving lysosomal function mitigated TBOEP-induced neurotoxicity, supporting lysosomal dysfunction as a primary contributor to the observed pathology. Collectively, our findings identify TBOEP as a potential environmental risk factor for neurodegeneration, providing important insights that could inform further studies assessing the environmental health risks of organophosphate esters.\n --- END ACTUAL ABSTRACT FOR 42114425 ---\n\n- ERROR: You cited ID: 30550357 for the quote: \"Remarkably, re-acidification restores citrate synthase activity and ATP content in an insulin secreting \u03b2-cell line.\"\n FACT: Strict Misquote Detected!

This effect is in part caused by a decline in mitochondrial function as well as by a reduction in lysosomal acidification. Because both mitochondria and lysosomes can alter one another's function, it remains unclear which initiating dysfunction sets off the detrimental cascade of LT, ultimately leading to \u03b2-cell failure. Here, we investigated the effects of restoring lysosomal acidity on mitochondrial function under LT. Our results show that LT induces a dose-dependent lysosomal alkalization accompanied by an increase in mitochondrial mass. This increase is due to a reduction in mitochondrial turnover as analyzed by MitoTimer, a fluorescent protein for which the emission is regulated by mitochondrial clearance rate. Mitochondrial oxygen consumption rate, citrate synthase activity, and ATP content are all reduced by LT. Restoration of lysosomal acidity using lysosome-targeted nanoparticles is accompanied by stimulation of mitochondrial turnover as revealed by mitophagy measurements and the recovery of mitochondrial mass. Remarkably, re-acidification restores citrate synthase activity and ATP content in an insulin secreting \u03b2-cell line (INS-1). Furthermore, nanoparticle-mediated lysosomal reacidification rescues mitochondrial maximal respiratory capacity in both INS-1 cells and primary mouse islets. Therefore, our results indicate that mitochondrial dysfunction is downstream of lysosomal alkalization under lipotoxic conditions and that recovery of lysosomal acidity is sufficient to restore the bioenergetic defects.-Assali, E.

This study aimed to investigate whether NPs exposure accelerates osteoarthritis progression in osteoarthritic mice, to elucidate the underlying molecular mechanisms, and to evaluate the therapeutic potential of quercetin. OA was induced in C57BL/6 mice via destabilization of the medial meniscus (DMM), with or without exposure to 20-nm polystyrene NPs (0.5\u00a0mg/mL in drinking water). For therapeutic intervention, quercetin (25 or 50\u00a0mg/kg) or indomethacin (3\u00a0mg/kg) was administered daily. Cartilage destruction was assessed by histology using the Osteoarthritis Research Society International (OARSI) scoring system, immunohistochemistry, and X-ray. In vitro, primary murine chondrocytes were treated with NPs and/or quercetin. Mechanisms were investigated using transmission electron microscopy, immunofluorescence, Western blot, organelle staining, and siRNA knockdown. NPs exposure significantly accelerated cartilage degradation and OA progression in DMM mice. Internalized NPs accumulated in chondrocyte lysosomes, inducing lysosomal membrane permeabilization (LMP), cathepsin B release, and subsequent NLRP3 inflammasome activation, leading to pyroptosis (evidenced by cleavage of gasdermin D N-terminal, GSDMD-N) and extracellular matrix loss. Quercetin restored lysosomal integrity, inhibited the LMP-NLRP3-pyroptosis axis in chondrocytes, and markedly attenuated NPs-aggravated cartilage destruction in vivo. This study identifies nanoplastics as novel environmental risk factors that act as pathological amplifiers in the context of osteoarthritis by inducing lysosomal destabilization-mediated pyroptosis in chondrocytes. Quercetin alleviates this pathological cascade by stabilizing lysosomes, highlighting its potential as a therapeutic agent against nanoplastics-exacerbated OA.\n --- END ACTUAL ABSTRACT FOR 42009103 ---\n\n- ERROR: You cited ID: 41643617 for the quote: \"PS-NPs exposure upregulated mTOR signaling, thereby leading to lysosomal dysfunction and a blockade of autophagic flux.\"\n FACT: Strict Misquote Detected!

Recent findings suggest that abnormal aggregation of pathogenic proteins within the nervous system may contribute to the neurotoxicity induced by nanoplastics, yet the molecular mechanisms regulating this pathological cascade remain unclear. Here, we used immature mice as an experimental model to represent infants and young children who are at higher risk of nanoplastics exposure, to elucidate the molecular mechanisms underlying neurotoxicity induced by exposure to polystyrene nanoplastics (PS-NPs) during early life. The results showed that environmentally relevant doses of PS-NPs penetrated the brains of immature mice and induced behavioral and emotional disorders. Proteomic analysis identified the mTOR signaling pathway as a candidate pathway responding to PS-NPs exposure in the immature mouse brain. Rapamycin intervention and quantitative validation further demonstrated that PS-NPs exposure upregulated mTOR signaling, thereby leading to lysosomal dysfunction and a blockade of autophagic flux, which in turn disrupted proteostasis and ultimately caused neurotoxicity. Furthermore, treatment with sodium 4-phenylbutyrate (4-PBA) confirmed that proteostasis imbalance, characterized by activation of the unfolded protein response, was a direct driver of this neurotoxicity. Notably, both rapamycin and 4-PBA treatments alleviated neurotoxicity resulting from PS-NPs exposure by restoring proteostasis. Together, these findings highlight dysregulation of the autophagy-lysosome pathway mediated by mTOR as a central mechanism of PS-NPs-induced neurotoxicity in immature mice and suggest lysosomal regulation for proteostasis remodeling as a prospective therapeutic strategy against neurological hazards related to nanoplastics.\n --- END ACTUAL ABSTRACT FOR 41643617 ---\n\n- ERROR: You cited ID: 41416489 for the quote: \"PTZ release increases intracellular acidity, which further triggers assembly disintegration, accelerates the release of iron and manganese ions, and neutralizes the extracellular microenvironment.\"\n FACT: Strict Misquote Detected!

Here, we integrate the proton pump inhibitor pantoprazole (PTZ) with manganese ferrite nanoparticles (MFNs) within an acidity-responsive polymer for enhanced ferroptosis and cGAS-STING activation mediated immunotherapy. This assembly (PTZ/MFNAs) facilitates tumor accumulation through the enhanced permeability and retention effect while initially restricting the release of metal ions. Upon reaching the tumor site, PTZ release increases intracellular acidity, which further triggers assembly disintegration, accelerates the release of iron and manganese ions, and neutralizes the extracellular microenvironment to alleviate immunosuppression. The released manganese ions synergistically collaborate with iron ions to amplify reactive oxygen species (ROS) generation for ferroptosis while activating the cyclic guanosine monophosphate-adenosine monophosphate synthase-stimulator of interferon genes (cGAS-STING) pathway, stimulating innate immunity. This potentiation of innate immunity, coupled with the reversal of TME immunosuppression, collectively and effectively inhibits tumor growth and metastasis.

Environmental toxins are considered the main etiological factor. The increasing use of polystyrene nanoparticles (PS-NPs) has raised concerns about their potential neurotoxic effects in PD. This study aimed to investigate the impact of PS-NPs on the onset and progression of PD and the underlying mechanisms. The breach of the blood-brain barrier (BBB) by PS-NPs was assessed using bioluminescence imaging, fluorescence observation, Pyrolysis-Gas Chromatography-Mass Spectrometry (Py-GCMs), transmission electron microscope (TEM), and Evans blue staining. To evaluate the potential promotion of PD by PS-NPs, a 30-day repeated oral administration study was conducted in vivo, during which behavioral changes and alterations in dopaminergic neurons in the substantia nigra were assessed. In vitro cytotoxicity assays were performed following PS-NPs intervention. Molecular biology techniques, including Western blotting and immunofluorescence, were employed to analyze proteins related to pyroptosis and autophagy-lysosomal pathway in both in vivo and in vitro settings. Additionally, proteomic sequencing was utilized to identify the upstream regulator of the autophagy-lysosomal pathway (ALP), and the effects of modulating this target protein on the ALP-pyroptosis pathway were analyzed. Bioluminescence imaging and Py-GCMs confirmed that PS-NPs entered the brain within 1.5\u00a0h. Evans blue staining and TEM showed PS-NPs damaged the BBB. The 30-day oral toxicity revealed that PS-NPs exacerbated behavioral abnormalities and caused dopaminergic neuron loss. Western blotting and immunofluorescence indicated that PS-NPs induced pyroptosis, disrupted autophagic flux, and lowered protein levels involved in autophagosome-lysosome fusion, both in vivo and in vitro. Furthermore, PS-NPs activated the mechanistic target of rapamycin (mTOR) and inhibited the nuclear translocation of Transcription Factor EB (TFEB). Proteomic sequencing identified a deficit of Tuberous Sclerosis Complex (TSC) 2 protein within the mTOR pathway. Immuno-coprecipitation and Coomassie Blue Fast Staining revealed that PS-NPs bound to TSC2 protein, causing disassembly of TSC1-TSC2 complex. These findings underscore how PS-NPs accelerated PD onset and progression by disrupting autophagosome-lysosome fusion through TSC2-mTOR-TFEB axis, which triggered protein degradation disorders and pyroptosis in dopaminergic neurons. The molecular mechanisms could inform environmental safety regulations concerning nanoplastics and inspire therapeutic strategies for PD.\n --- END ACTUAL ABSTRACT FOR 40474178 ---\n\n- ERROR: You cited ID: 39740740 for the quote: \"The blockade of autophagy and lysosomal dysfunction, culminating in lysosomal membrane permeabilization (LMP) induced necroptosis, constitutes one of the mechanisms contributing to the cytotoxicity of NP.\"\n FACT: Strict Misquote Detected!

Consequently, the toxicology of such particles has emerged as a pivotal research interests in recent years. In this study, NP was synthesized successfully with an average particle size of 100\u00a0nm using a emulsion polymerization method as model particles. Following co-incubation of IEC-6 cells with NP for 24-168\u00a0h, a notable inhibition of cell viability and proliferation was observed. The significant activation of autophagy and a concomitant blockage of autophagic flux in IEC-6 cells after 24-72\u00a0h of co-incubation with NP were unveiled by transmission electron microscopy, western blotting, and double-fluorescent autophagy analysis. A significant increase in the number of lysosomes and an increase in the expression of hydrolase CTSB were detected, indicating dysregulation of lysosomal function. The subsequent transcriptomic and metabolomics analyses, coupled with the observation of activated lysosomes and the RIPK1-RIPK3-MLKL/PYGL pathway, led us to posit that the blockade of autophagy and lysosomal dysfunction, culminating in lysosomal membrane permeabilization (LMP) induced necroptosis, constitutes one of the mechanisms contributing to the cytotoxicity of NP.

Devising strategies to rescue this macrophage lysosomal dysfunction is a novel therapeutic measure. Nanoparticles have emerged as an effective platform to both target specific tissues and serve as drug delivery vehicles. In most cases, administered nanoparticles are taken up non-selectively by the mononuclear phagocyte system including monocytes/macrophages leading to the undesirable degradation of cargo in lysosomes. We took advantage of this default route to target macrophage lysosomes to rectify their acidity in disease states such as atherosclerosis. Herein, we develop and test two commonly used acidic nanoparticles, poly-lactide-co-glycolic acid (PLGA) and polylactic acid (PLA), both in vitro and in vivo. Our results in cultured macrophages indicate that the PLGA-based nanoparticles are the most effective at trafficking to and enhancing acidification of lysosomes. PLGA nanoparticles also provide functional benefits including enhanced lysosomal degradation, promotion of macroautophagy/autophagy and protein aggregate removal, and reduced apoptosis and inflammasome activation. We demonstrate the utility of this system in vivo, showing nanoparticle accumulation in, and lysosomal acidification of, macrophages in atherosclerotic plaques. Long-term administration of PLGA nanoparticles results in significant reductions in surrogates of plaque complexity with reduced apoptosis, necrotic core formation, and cytotoxic protein aggregates and increased fibrous cap formation. Taken together, our data support the use of acidic nanoparticles to rescue macrophage lysosomal dysfunction in the treatment of atherosclerosis.Abbreviations: BCA: brachiocephalic arteries; FACS: fluorescence activated cell sorting; FITC: fluorescein-5-isothiocyanatel; IL1B: interleukin 1 beta; LAMP: lysosomal associated membrane protein; LIPA/LAL: lipase A, lysosomal acid type; LSDs: lysosomal storage disorders; MAP1LC3/LC3: microtubule associated protein 1 light chain 3; MFI: mean fluorescence intensity; MPS: mononuclear phagocyte system; PEGHDE: polyethylene glycol hexadecyl ether; PLA: polylactic acid; PLGA: poly-lactide-co-glycolic acid; SQSTM1/p62: sequestosome 1.\n --- END ACTUAL ABSTRACT FOR 35982578 ---\n\n\n\u2705 PASSED (DO NOT CHANGE THESE):\n- \"Functional assays further confirmed that TBOEP significantly impaired lysosomal acidification.\" (Source: 42114425)\n- \"These nanomaterials were developed to locally acidify impaired lysosomes and restore their degradative capacity.\" (Source: 42033266)\n- \"Emerging evidence links \u03b1Syn accumulation to impaired lysosomal acidification and defective autophagy-lysosomal degradation, which are central to disease progression.\" (Source: 42033266)\n- \"Corona formation induced conformational remodeling of LYZ, enhanced its enzymatic activity, and prolonged its membrane retention.\" (Source: 42307976)\n- \"LT induces a dose-dependent lysosomal alkalization accompanied by an increase in mitochondrial mass.\" (Source: 30550357)\n- \"Pharmacological intervention with rapamycin or acidic nanoparticles restores lysosomal pH and rescue mitochondrial function, representing a novel therapeutic approach for GBA1-PD .\" (Source: 42310725)\n- \"Nanoplastics induced approximately 20% more lysosomal damage than microplastics, suggesting a distinct toxicity mechanism.\" (Source: 41457494)\n- \"MSC-PLGA-NPs, a novel multifunctional nanoparticle platform, synergistically integrates the BBB penetration capability of MSC-NVs and the lysosomal acidification function of PLGA.\" (Source: 41247156)\n- \"PS-NP exposure hampered p62 degradation, leading to LC3B accumulation and decreased cathepsin B and D activity.\" (Source: 40607257)\n- \"The findings of this study suggest that the Nd mutant silkworm can be used as an animal model for studying protein aggregation diseases.\" (Source: 40413758)\n- \"NPs resulted in a loss of lysosomal membrane stability and a reduction in immune resistance.\" (Source: 39853018)\n- \"A significant increase in the number of lysosomes and an increase in the expression of hydrolase CTSB were detected, indicating dysregulation of lysosomal function.\" (Source: 39740740)\n- \"High levels of free fatty acids in the liver impair hepatic lysosomal acidification and reduce autophagic flux.\" (Source: 37142604)\n- \"In established in vivo high fat diet mouse models of NAFLD, re-acidification of lysosomes via acNP treatment restores autophagy and mitochondria function to lean, healthy levels.\" (Source: 37142604)\n\n\nINSTRUCTION: Study the actual abstracts provided.

Evidence confirms that nanoplastics (NPs) frequently disrupt lysosomal integrity, leading to alkalization and impaired degradative capacity. Conversely, engineered acidifying nanoparticles successfully restore lysosomal pH, autophagic flux, and mitochondrial function in several disease models, indicating high cross-applicability for managing environmental toxicant-driven organelle pathology.\n\n### [INTRODUCTION & JUSTIFICATION]\nEmerging literature establishes a clear mechanistic convergence between nanoplastic (NP) exposure and lysosomal pathology. Environmental contaminants, particularly polystyrene nanoplastics, consistently trigger lysosomal membrane permeabilization (LMP), alkalization, and the blockage of autophagic flux. The resulting reduction in cathepsin activity and clearance capacity directly contributes to neurodegenerative and metabolic disorders. Given that lysosome-acidifying nanoparticles have demonstrated the ability to rescue identical defects\u2014such as those induced by lipotoxicity, GBA1 mutations, or Alzheimer's-related protein aggregation\u2014it is mechanistically plausible that this platform can be adapted to mitigate nanoplastic-induced cytotoxicity. The restoration of acidic environments in lysosomes via pH-modulating materials addresses the primary functional deficiency caused by NP accumulation, thereby restoring proteostasis and cellular viability.\n\n### [DISCUSSION: NOVEL & OVERLOOKED]\n* Lysosomal alkalization induced by NPs acts as a \"degradative bottleneck,\" sharing distinct pathogenic features with familial Parkinson\u2019s disease and non-alcoholic fatty liver disease (NAFLD).\n* The \"Alkaline-Hammer\" strategy demonstrates that pH modulation can be used not only to rescue function but to actively induce \"alkaliptosis\" in targeted oncological applications.\n* Zinc-mediated lysosomal activation represents a non-nanoparticle alternative for achieving similar restorative outcomes in autophagic-lysosomal pathways.\n* There is a critical, size-dependent internalization mechanism for NPs; while 20-50 nm particles penetrate lysosomes readily, larger particles may rely on alternative phagocytic uptake mechanisms.\n* The restoration of lysosomal acidity is sufficient to reverse downstream mitochondrial dysfunction, positioning the lysosome as an upstream master regulator of bioenergetics.\n* Evidence suggests that the \"ECM-lysosome axis\" creates a self-amplifying pathological loop in degenerative conditions, which nanoparticles may interrupt.\n\n### [EVIDENCE, METHODOLOGY & CITATIONS]\n1.

This effect is in part caused by a decline in mitochondrial function as well as by a reduction in lysosomal acidification. Because both mitochondria and lysosomes can alter one another's function, it remains unclear which initiating dysfunction sets off the detrimental cascade of LT, ultimately leading to \u03b2-cell failure. Here, we investigated the effects of restoring lysosomal acidity on mitochondrial function under LT. Our results show that LT induces a dose-dependent lysosomal alkalization accompanied by an increase in mitochondrial mass. This increase is due to a reduction in mitochondrial turnover as analyzed by MitoTimer, a fluorescent protein for which the emission is regulated by mitochondrial clearance rate. Mitochondrial oxygen consumption rate, citrate synthase activity, and ATP content are all reduced by LT. Restoration of lysosomal acidity using lysosome-targeted nanoparticles is accompanied by stimulation of mitochondrial turnover as revealed by mitophagy measurements and the recovery of mitochondrial mass. Remarkably, re-acidification restores citrate synthase activity and ATP content in an insulin secreting \u03b2-cell line (INS-1). Furthermore, nanoparticle-mediated lysosomal reacidification rescues mitochondrial maximal respiratory capacity in both INS-1 cells and primary mouse islets. Therefore, our results indicate that mitochondrial dysfunction is downstream of lysosomal alkalization under lipotoxic conditions and that recovery of lysosomal acidity is sufficient to restore the bioenergetic defects.-Assali, E.

The carbon dots were directly functionalized by abundant amino groups during synthesis and exhibited dual emission bands at 439 and 550\u00a0nm under single-wavelength excitation of 380\u00a0nm without any additional modification. In addition to its small size, the established sensor had good biocompatibility. Owing to its abundant amino groups and good hydrophilicity, the sensor is able to\u00a0target lysosome with high Pearson's colocalization coefficients (0.935 and 0.924) and responds to change of lysosomal pH in living cells. It also had excellent pH sensitivity and reversibility, and anti-interference capability, thus enabling sensing pH change in intracellular environment in real time, as demonstrated by successful monitoring of lysosomal pH changes during lysosomal alkalization, dexamethasone-induced stimulation, and stress in Michigan Cancer Foundation-7 cells (blue channel, excitation\u2009=\u2009405\u00a0nm and emission\u2009=\u2009419-459\u00a0nm bandpass; and yellow channel, excitation\u2009=\u2009405\u00a0nm and emission\u2009=\u2009530-570\u00a0nm bandpass).

Therefore, in-depth knowledge of their uptake, trafficking and effects at cellular and systemic levels is essential to understand their potential impacts for aquatic species. In this work, zebrafish (Danio rerio) was used as a model and our aims were: i) to determine the distribution, uptake, trafficking, degradation and genotoxicity of polystyrene (PS) NPs of different sizes in a zebrafish cell line; ii) to study PS NPs accumulation, migration of immune cells and genotoxicity in larvae exposed to PS NPs; and iii) to assess how PS NPs condition the survival of zebrafish larvae exposed to a pathogen and/or how they impact the resistance of an immunodeficient zebrafish. Our results revealed that the cellular distribution differed depending on the particle size: the 50\u00a0nm\u00a0PS NPs were more homogeneously distributed in the cytoplasm and the 1\u00a0\u03bcM\u00a0PS NPs more agglomerated. The main endocytic mechanisms for the uptake of NPs were dynamin-dependent internalization for the 50\u00a0nm NPs and phagocytosis for the 1\u00a0\u03bcm nanoparticles. In both cases, degradation in lysosomes was the main fate of the PS NPs, which generated alkalinisation and modified cathepsin genes expression. These effects at cellular level agree with the results in\u00a0vivo, since lysosomal alkalization increases oxidative stress and vice versa. Nanoparticles mainly accumulated in the gut, where they triggered reactive oxygen species, decreased expression of the antioxidant gene catalase and induced migration of immune cells. Finally, although PS NPs did not induce mortality in wild-type larvae, immunodeficient and infected larvae had decreased survival upon exposure to PS NPs. This fact could be explained by the mechanical disruption and/or the oxidative damage caused by these NPs that increase their susceptibility to pathogens.",

Quercetin (Qu), a flavonoid antioxidant with autophagy-enhancing effect, has protective effect on Cd-induced toxicity, but whether it can prevent Cd-induced nephrotoxicity via restoration of autophagy remains unknown. Here, primary rat proximal tubular (rPT) cells were exposed to Cd and/or Qu in vitro to clarify this issue. Data first showed that Cd-impaired autophagic flux was markedly alleviated by Qu, including decreased levels of autophagy marker proteins and recovery of autophagosome-lysosome fusion targeted for lysosomes. Meanwhile, Cd-induced lysosomal alkalization due to v-ATPases inhibition was prominently recovered by Qu. Accordingly, Qu enhanced Cd-diminished lysosomal degradation capacity and lysosome-related gene transcription levels. Notably, Qu improved Cd-inhibited TFEB nuclear translocation and its gene transcription level. Furthermore, data showed that the restoration of Cd-impaired autophagy-lysosome pathway and resultant alleviation of cytotoxicity by Qu are TFEB-dependent using TFEB gene silencing and overexpression technologies. In summary, these data provide novel evidences that the protective action of Qu against Cd-induced autophagy inhibition is attributed to its restoration of lysosomal dysfunction, which is dependent on TFEB.",
"33838376": "ID: 33838376\nTitle: PM2.5 and the typical components cause organelle damage, apoptosis and necrosis: Role of reactive oxygen species.\nAbstract: In this research, the organelle damage, apoptosis and necrosis induced by PM2.5, BC and Kaolin were studied using human bronchial epithelial (16HBE) cells. PM2.5, BC and Kaolin all induce cell death, LDH release and excess intracellular ROS generation. For the organelle injuries, Kaolin and high-dose PM2.5 (240 \u03bcg/mL) cause lysosomal acidification, but BC causes lysosomal alkalization (lysosomal membrane permeabilization, LMP). BC and Kaolin cause the loss of mitochondrial membrane potential (MMP), while PM2.5 does not. For the cell death mode, PM2.5 causes both apoptosis and necrosis. However only necrosis has been detected in the BC and Kaolin treated groups, indicating the more severe cellular insult. Excess ROS generation is involved in the organelle damage and cell death. ROS contributes to the BC-induced LMP and necrosis, but does not significantly affect the Kaolin-induced MMP loss and necrosis. Therefore, the BC component in PM2.5 may cause cytotoxicity via ROS-dependent pathways, the Kaolin component may damage cells via ROS-independent mechanisms such as strong interaction. The PM2.5-induced apoptosis and necrosis can be partially mitigated after the removal of ROS, indicating the existence of both the ROS-dependent and ROS-independent mechanisms due to the complicated PM2.5 components. BC represents the anthropogenic source component in PM2.5, while Kaolin represents the natural source component. Our results provide knowledge on the toxic mechanisms of typical PM2.5 components at the cellular and subcellular levels.",
"33962064": "ID: 33962064\nTitle: Lysosomal alkalization to potentiate eradication of intra-osteoblastic Staphylococcus aureus in the bone and joint infection setting.\nAbstract: Beyond intracellular penetration, acidic lysosomal pH might affect the intracellular activity of some antimicrobials. This study evaluated the ability of lysosomotropic alkalizing agents to potentiate the antimicrobial eradication of an intra-osteoblastic Staphylococcus aureus reservoir in the setting of bone and joint infection (BJI). MICs of 16 anti-staphylococcal molecules active against methicillin-sensitive S.\u00a0aureus (MSSA) were evaluated at pH 5 and pH 7. Additionally, the lysosomal alkalizing potential (spectrofluorometry) and cytotoxicity (MTT assay) of hydroxychloroquine, amantadine and ammonium chloride were assessed. The results led to further investigation of clindamycin, cotrimoxazole, daptomycin and levofloxacin-alone or in combination with hydroxychloroquine-in an in\u00a0vitro model of osteoblast infection. The impact of hydroxychloroquine on autophagy was finally investigated using Western blot detection of two autophagic flux indicators, the LC3 membrane protein and the SQSTM1 cargo protein. Daptomycin, cotrimoxazole, clindamycin and levofloxacin alone significantly decreased the intracellular staphylococcal reservoir (5.12 log10\u00a0CFU/100\u00a0000\u00a0cells) by 0.14 (95%CI 0.01-0.34), 0.25 (95%CI 0.12-0.43), 0.16 (95%CI 0.004-0.39) and 1.18 (95%CI 1.04-1.38) log10\u00a0CFU/100\u00a0000\u00a0cells, respectively (p\u00a0<\u00a010-3). Adding hydroxychloroquine (20 mg/L) increased intralysosomal pH from 4.8 to 7, and concomitantly the inoculum of each antimicrobial was reduced by 0.50 (95%CI 0.30-0.84), 0.73 (95%CI 0.59-0.96), 0.59 (95%CI 0.46-0.78) and 1.8 (95%CI 1.66-2.1) log10\u00a0CFU/100\u00a0000\u00a0cells, respectively (p\u00a0<\u00a010-4). Cellular levels of LC3II and SQSTM1 showed that hydroxychloroquine has direct activity on the autophagic flux, fostering the eradication of intracellular S.\u00a0aureus by antimicrobials. At high concentrations, hydroxychloroquine used as an adjuvant to antimicrobials improves eradication of an S.\u00a0aureus intra-osteoblastic reservoir in our in\u00a0vitro cell infection model. These findings advocate further in\u00a0vivo evaluation of alkalization efficacy and tolerance in S.\u00a0aureus BJI.",
"34217793": "ID: 34217793\nTitle: Polystyrene nanoplastics dysregulate lipid metabolism in murine macrophages in vitro.\nAbstract: Micro and nanoplastics are one of the major emerging environmental contaminants. Their impact on human health is less explored. There are several in vitro studies on their cellular uptake and accumulation, where micro and nanoplastics were mostly reported to be non-cytotoxic. The effects caused by the direct contact of nanoplastics with the immune system, especially at the cellular level is less known. Here we report that RAW 264.7 macrophages undergo differentiation into lipid laden foam cells when exposed to polystyrene nanoplastics (50 \u03bcg/mL). We found that exposure of RAW 264.7 macrophages to sulfate-modified polystyrene nanoplastics results in the accumulation of lipid droplets in the cytoplasm leading to foam cell formation. Exposure to high concentration of polystyrene nanoplastics (100 and 200 \u03bcg/mL) results in increased reactive oxygen species and impair lysosomes in macrophages. The exposure of BV2 microglial cells to polystyrene nanoplastics (50 \u03bcg/mL) induces lipid accumulation. In addition, our results indicate the role of polystyrene nanoplastics in altering the lipid metabolism in murine macrophages in vitro. In the present study we reported that polystyrene nanoplastics stabilized with anionic surfactants can be potent stimuli for lipotoxicity and foam cell formation leading to the pathogenesis of atherosclerosis posing major threat for animal and human health.",
"34445748": "ID: 34445748\nTitle: Targeting Lysosomes to Reverse Hydroquinone-Induced Autophagy Defects and Oxidative Damage in Human Retinal Pigment Epithelial Cells.\nAbstract: In age-related macular degeneration (AMD), hydroquinone (HQ)-induced oxidative damage in retinal pigment epithelium (RPE) is believed to be an early event contributing to dysregulation of inflammatory cytokines and vascular endothelial growth factor (VEGF) homeostasis. However, the roles of antioxidant mechanisms, such as autophagy and the ubiquitin-proteasome system, in modulating HQ-induced oxidative damage in RPE is not well-understood. This study utilized an in-vitro AMD model involving the incubation of human RPE cells (ARPE-19) with HQ. In comparison to hydrogen peroxide (H2O2), HQ induced fewer reactive oxygen species (ROS) but more oxidative damage as characterized by protein carbonyl levels, mitochondrial dysfunction, and the loss of cell viability. HQ blocked the autophagy flux and increased proteasome activity, whereas H2O2 did the opposite. Moreover, the lysosomal membrane-stabilizing protein LAMP2 and cathepsin D levels declined with HQ exposure, suggesting loss of lysosomal membrane integrity and function. Accordingly, HQ induced lysosomal alkalization, thereby compromising the acidic pH needed for optimal lysosomal degradation. Pretreatment with MG132, a proteasome inhibitor and lysosomal stabilizer, upregulated LAMP2 and autophagy and prevented HQ-induced oxidative damage in wildtype RPE cells but not cells transfected with shRNA against ATG5. This study demonstrated that lysosomal dysfunction underlies autophagy defects and oxidative damage induced by HQ in human RPE cells and supports lysosomal stabilization with the proteasome inhibitor MG132 as a potential remedy for oxidative damage in RPE and AMD.",
"34500008": "ID: 34500008\nTitle: Perfluorooctane sulfonate induces autophagy-dependent lysosomal membrane permeabilization by weakened interaction between tyrosinated alpha-tubulin and spinster 1.\nAbstract: Perfluorooctane sulfonate (PFOS) is one kind of persistent organic pollutants. In previous study, we found that PFOS induced autophagy-dependent lysosomal membrane permeabilization (LMP) in hepatocytes, and siRNA against lysosomal permease spinster 1 (SPNS1) relieved PFOS-induced LMP. However, whether and how SPNS1 functioned as the link between autophagy and LMP was still not defined. In this study, we constructed a stable cell line expressing high levels of SPNS1. We found that SPNS1 interacted specifically with \u03b1-tubulin of tyrosinated isotype by pull-down assay. After treatment with PFOS, the level of tyrosinated \u03b1-tubulin was autophagy-dependently decreased. SPNS1-tyrosinated \u03b1-tubulin interaction was disrupted subsequently, which led to LMP eventually. We also found that stable high-expression of SPNS1 in hepatocytes accelerated lysosomal acidification, and deteriorated PFOS-induced LMP. This study pointed out that SPNS1-tyrosinated \u03b1-tubulin interaction mediated the cross-talk between autophagy and LMP induced by PFOS, shedding new light on the mechanism of PFOS hepatotoxicity.",
"34528688": "ID: 34528688\nTitle: Cholesteryl hemiazelate causes lysosome dysfunction impacting vascular smooth muscle cell homeostasis.\nAbstract: In atherosclerotic lesions, vascular smooth muscle cells (VSMCs) represent half of the foam cell population, which is characterized by an aberrant accumulation of undigested lipids within lysosomes. Loss of lysosome function impacts VSMC homeostasis and disease progression. Understanding the molecular mechanisms underlying lysosome dysfunction in these cells is, therefore, crucial. We identify cholesteryl hemiazelate (ChA), a stable oxidation end-product of cholesteryl-polyunsaturated fatty acid esters, as an inducer of lysosome malfunction in VSMCs. ChA-treated VSMCs acquire a foam-cell-like phenotype, characterized by enlarged lysosomes full of ChA and neutral lipids. The lysosomes are perinuclear and exhibit degradative capacity and cargo exit defects. Lysosome luminal pH is also altered. Even though the transcriptional response machinery and autophagy are not activated by ChA, the addition of recombinant lysosomal acid lipase (LAL) is able to rescue lysosome dysfunction. ChA significantly affects VSMC proliferation and migration, impacting atherosclerosis. In summary, this work shows that ChA is sufficient to induce lysosomal dysfunction in VSMCs, that, in ChA-treated VSMCs, neither lysosome biogenesis nor autophagy are triggered, and, finally, that recombinant LAL can be a therapeutic approach for lysosomal dysfunction.",
"35022393": "ID: 35022393\nTitle: Danger signal extracellular calcium initiates differentiation of monocytes into SPP1/osteopontin-producing macrophages.\nAbstract: The danger signal extracellular calcium is pathophysiologically increased in the synovial fluid of patients with rheumatoid arthritis (RA). Calcium activates the NLRP3-inflammasome via the calcium-sensing receptor in monocytes/macrophages primed by lipopolysaccharide, and this effect is mediated by the uptake of calciprotein particles (CPPs) formed out of calcium, phosphate, and fetuin-A. Aim of the study was to unravel the influence of calcium on monocytes when the priming signal is not present. Monocytes were isolated from the blood of healthy controls and RA patients. Macrophages were characterized using scRNA-seq, DNA microarray, and proteomics. Imaging flow cytometry was utilized to study intracellular events. Here we show that extracellular calcium and CPPs lead to the differentiation of monocytes into calcium-macrophages when the priming signal is absent. Additional growth factors are not needed, and differentiation is triggered by calcium-dependent CPP-uptake, lysosomal alkalization due to CPP overload, and TFEB- and STAT3-dependent increased transcription of the lysosomal gene network. Calcium-macrophages have a needle-like shape, are characterized by excessive, constitutive SPP1/osteopontin production and a strong pro-inflammatory cytokine response. Calcium-macrophages differentiated out of RA monocytes show a stronger manifestation of this phenotype, suggesting the differentiation process might lead to the pro-inflammatory macrophage response seen in the RA synovial membrane.",
"35785701": "ID: 35785701\nTitle: Lysosomal sequestration of weak base drugs, lysosomal biogenesis, and cell cycle alteration.\nAbstract: Lysosomes, now known to take part in multiple cellular functions, also respond to various stress stimuli. These include biogenesis in response to nanomolar concentrations of hydrophobic weak-base anticancer drugs. However, since lysosomal stress mediated by accumulation of weak-base drugs at such concentrations has never been proven and these drugs have diverse effects on malignant cells, we investigated whether the interpretation of the data was true. We found that lysosomal accumulation of the drugs daunorubicin, doxorubicin, mitoxantrone, symadex, chloroquine, clomipramine and sunitinib alone, was insufficient to induce lysosomal alkalization i.e., lysosomal stress-mediated biogenesis at nanomolar concentrations. Instead, we found that some of the drugs used induced G2 phase arrest and lysosomal biogenesis that is associated with activation of transcription factor EB (TFEB). Similarly, cantharidin, a control compound that does not belong to the weak base drugs, induced cell cycle arrest in the G2 phase associated with TFEB-driven lysosomal biogenesis. Overall none of the tested drugs caused stress-induced lysosomal biogenesis at nanomolar concentrations. However, daunorubicin, doxorubicin, mitoxantrone, symadex and cantharidin induced a massive block in the G2 phase of the cell cycle which is naturally associated with TFEB-driven lysosomal biogenesis.",
"35982578": "ID: 35982578\nTitle: Use of acidic nanoparticles to rescue macrophage lysosomal dysfunction in atherosclerosis.\nAbstract: Dysfunction in the macrophage lysosomal system including reduced acidity and diminished degradative capacity is a hallmark of atherosclerosis, leading to blunted clearance of excess cellular debris and lipids in plaques and contributing to lesion progression. Devising strategies to rescue this macrophage lysosomal dysfunction is a novel therapeutic measure. Nanoparticles have emerged as an effective platform to both target specific tissues and serve as drug delivery vehicles. In most cases, administered nanoparticles are taken up non-selectively by the mononuclear phagocyte system including monocytes/macrophages leading to the undesirable degradation of cargo in lysosomes. We took advantage of this default route to target macrophage lysosomes to rectify their acidity in disease states such as atherosclerosis. Herein, we develop and test two commonly used acidic nanoparticles, poly-lactide-co-glycolic acid (PLGA) and polylactic acid (PLA), both in vitro and in vivo. Our results in cultured macrophages indicate that the PLGA-based nanoparticles are the most effective at trafficking to and enhancing acidification of lysosomes. PLGA nanoparticles also provide functional benefits including enhanced lysosomal degradation, promotion of macroautophagy/autophagy and protein aggregate removal, and reduced apoptosis and inflammasome activation. We demonstrate the utility of this system in vivo, showing nanoparticle accumulation in, and lysosomal acidification of, macrophages in atherosclerotic plaques. Long-term administration of PLGA nanoparticles results in significant reductions in surrogates of plaque complexity with reduced apoptosis, necrotic core formation, and cytotoxic protein aggregates and increased fibrous cap formation. Taken together, our data support the use of acidic nanoparticles to rescue macrophage lysosomal dysfunction in the treatment of atherosclerosis.Abbreviations: BCA: brachiocephalic arteries; FACS: fluorescence activated cell sorting; FITC: fluorescein-5-isothiocyanatel; IL1B: interleukin 1 beta; LAMP: lysosomal associated membrane protein; LIPA/LAL: lipase A, lysosomal acid type; LSDs: lysosomal storage disorders; MAP1LC3/LC3: microtubule associated protein 1 light chain 3; MFI: mean fluorescence intensity; MPS: mononuclear phagocyte system; PEGHDE: polyethylene glycol hexadecyl ether; PLA: polylactic acid; PLGA: poly-lactide-co-glycolic acid; SQSTM1/p62: sequestosome 1.",
"36108847": "ID: 36108847\nTitle: Responses of zebrafish (Danio rerio) cells to antibiotic erythromycin stress at the subcellular levels.\nAbstract: Erythromycin (ERY) is one of the most used antibiotics frequently detected in different aquatic environments and may bring burdens to aquatic ecosystems. However, the impacts of antibiotics on aquatic systems other than the antibiotic resistance genes remain largely unknown. In the present study, the responses to ERY exposure at the subcellular-organelle levels were for the first time investigated and imaged over 24 h. Exposure to ERY hampered the zebrafish (Danio rerio) cell growth and decreased the cell viability in a time-dependent mode. Meanwhile, exposure to a low concentration of ERY (73.4 \u03bcg L-1) induced reactive oxygen species (ROS) overproduction and lysosomal damage following lysosomal alkalization and swelling. In turn, the lysosomal stress was the major driver of altering the ROS level, superoxide dismutase (SOD) activity, and glutathione (GSH) content. Subsequently, mitochondria displayed dysfunction such as increased mitochondrial ROS, impaired mitophagy, and induced mitochondria-driven apoptosis, as well as impaired mitochondrial electron transport chain and loss of membrane potential. These results collectively demonstrated the subcellular sensitive machinery responses to ERY stress at environmentally relevant and slightly higher sub-lethal concentrations. ERY may induce switching from autophagy to apoptosis with corresponding changes in lysosomal activity, antioxidant activity, and mitochondrial activity. The findings provided important information on the physiological and subcellular responses of fish cells to ERY.",
"36132550": "ID: 36132550\nTitle: Chemosensitivity enhanced by autophagy inhibition based on a polycationic nano-drug carrier.\nAbstract: In recent years, with the increasing understanding of the role of autophagy in tumorigenesis and development, a steady stream of studies have demonstrated that both excessive induction and inhibition of autophagy could effectively improve the therapeutic efficacy against tumors during cytotoxic or molecularly targeted drug therapy. Among them, autophagy inhibition mediated by nanomaterials has become an appealing notion in nanomedicine therapeutics, since it can be exploited as an effective adjuvant in chemotherapy or as a potential anti-tumor agent. Herein, we constructed a pH-sensitive nanoplatform loaded with epirubicin (EPI) (mPEG-b-P(DPA-b-DMAEMA)/EPI), enabling effective autophagy inhibition in the process of tumor-targeting therapy and further sensitized the tumors to EPI. It was found that polycationic nanomicelles (PEDD-Ms) displayed specific localization in lysosomes after entering tumor cells and caused the impairment of lysosomal degradation capacity through lysosomal alkalization in a dose-dependent manner. HepG2 cells treated with PEDD-Ms displayed a large-scale accumulation of autophagosomes and LC3 (an autophagosome marker protein), and the degradation of the autophagy substrate p62 was also blocked, which indicated that these functional nanomicelles could significantly inhibit autophagy. Meanwhile, the typical morphological characteristics of autophagosomes were directly visualized by TEM. In vivo results also showed that the tumor-targeted and autophagy inhibition-associated nanoplatform therapy could effectively improve the therapeutic efficiency of EPI, which may be partially attributed to the fact that autophagy inhibition could enhance the sensitivity of tumor cells to EPI. Overall, we revealed the effect of polycationic nanomicelles on autophagic processes in tumor cells and explored their possible molecular mechanism, also considering the synergistic outcome between autophagy mediated by nanomaterials and chemotherapeutic drugs to improve the therapeutic effect on tumors.",

In HAND, the persistence of white matter alterations despite suppressive antiretroviral (ARV) therapy suggests that ARVs may be directly contributing to these impairments. Here, we report that a frontline ARV, bictegravir (BIC), significantly attenuates remyelination following cuprizone-mediated demyelination, a model that recapitulates acute demyelination, but has no impact on already formed mature myelin. Mechanistic studies utilizing primary rat oligodendrocyte precursor cells (OPCs) revealed that treatment with BIC leads to significant decrease in mature oligodendrocytes accompanied by lysosomal deacidification and impairment of lysosomal degradative capacity with no alterations in lysosomal membrane permeability or total lysosome number. Activation of the endolysosomal cation channel TRPML1 prevents both lysosomal deacidification and impairment of oligodendrocyte differentiation by BIC. Lastly, we show that deacidification of lysosomes by compounds that raise lysosomal pH is sufficient to prevent maturation of oligodendrocytes. Overall, this study has uncovered a critical role for lysosomal acidification in modulating oligodendrocyte function and has implications for neurologic diseases characterized by lysosomal dysfunction and white matter abnormalities.",

Maltol was proved to exert a protective effect on gut damage induced by carbon tetrachloride and cisplatin, indicating its confrontation with nanoplastics-induced intestinal toxicity. To explore the ameliorative effects of maltol on polystyrene nanoplastics (PS)-mediated enterotoxicity and the underlying mechanism, the mice were exposed to PS (100\u00a0mg/kg), combining with or without the treatment of maltol treatment at 50 and 100\u00a0mg/kg. We found PS exposure caused intestinal barrier damage and enterocyte apoptosis, while lysosomal dysfunction and autophagic substrate degradation arrest in enterocytes of mice were also observed. In addition, PS exacerbated the disturbance of the intestinal microbial community, affected the abundance of lysosome and apoptosis-related bacterial genes, and decreased the number of known short-chain fatty acid (SCFA) producing bacteria. However, those alterations were improved by the maltol treatment. Maltol also protected the human intestinal Caco-2\u00a0cells from PS-induce damages. Mechanistic studies showed maltol promoted TFEB nuclear translocation through the AMPK/mTOR signaling pathway to restore lysosomal function and reduce autophagy dependent apoptosis. The findings in the present work might help to elucidate the potential molecular mechanisms of PS-induced enterotoxicity. For the first time to our knowledge, the protective effect of maltol on PS-induced intestinal injury was studied from multiple perspectives, which provided a potential therapeutic approach for diseases caused by environmental pollution.",
"37104743": "ID: 37104743\nTitle: Migration from Lysosome to Nucleus: Monitoring Lysosomal Alkalization-Related Biological Processes with an Aminofluorene-Based Probe.\nAbstract: Aberrant lysosomal alkalization is associated with various biological processes, such as oxidative stress, cell apoptosis, ferroptosis, etc. Herein, we developed a novel aminofluorene-based fluorescence probe named FAN to monitor the lysosomal alkalization-related biological processes by its migration from lysosome to nucleus. FAN possessed NIR emission, large Stokes shift, high pH stability, and high photostability, making it suitable for real-time and long-term bioimaging. As a lysosomotropic molecule, FAN can accumulate in lysosomes first and then migrate to the nucleus by right of its binding capability to DNA after lysosomal alkalization. In this manner, FAN was successfully used to monitor these physiological processes which triggered lysosomal alkalization in living cells, including oxidative stress, cell apoptosis, and ferroptosis. More importantly, at higher concentrations, FAN could also serve as a stable nucleus dye for the fluorescence imaging of the nucleus in living cells and tissues. This novel multifunctional fluorescence probe shows great promise for application in lysosomal alkalization-related visual research and nucleus imaging.",
"37142604": "ID: 37142604\nTitle: Restoration of lysosomal acidification rescues autophagy and metabolic dysfunction in non-alcoholic fatty liver disease.\nAbstract: Non-alcoholic fatty liver disease (NAFLD) is the most common liver disease in the world. High levels of free fatty acids in the liver impair hepatic lysosomal acidification and reduce autophagic flux. We investigate whether restoration of lysosomal function in NAFLD recovers autophagic flux, mitochondrial function, and insulin sensitivity. Here, we report the synthesis of novel biodegradable acid-activated acidifying nanoparticles (acNPs) as a lysosome targeting treatment to restore lysosomal acidity and autophagy. The acNPs, composed of fluorinated polyesters, remain inactive at plasma pH, and only become activated in lysosomes after endocytosis. Specifically, they degrade at pH of ~6 characteristic of dysfunctional lysosomes, to further acidify and enhance the function of lysosomes. In established in vivo high fat diet mouse models of NAFLD, re-acidification of lysosomes via acNP treatment restores autophagy and mitochondria function to lean, healthy levels. This restoration, concurrent with reversal of fasting hyperglycemia and hepatic steatosis, indicates the potential use of acNPs as a first-in-kind therapeutic for NAFLD.",
"37251378": "ID: 37251378\nTitle: The internal dose makes the poison: higher internalization of polystyrene particles induce increased perturbation of macrophages.\nAbstract: Plastics are emerging pollutants of great concern. Macroplastics released in the environment degrade into microplastics and nanoplastics. Because of their small size, these micro and nano plastic particles can enter the food chain and contaminate humans with still unknown biological effects. Plastics being particulate pollutants, they are handled in the human body by scavenger cells such as macrophages, which are important players in the innate immune system. Using polystyrene as a model of micro and nanoplastics, with size ranging from under 100 nm to 6 microns, we have showed that although non-toxic, polystyrene nano and microbeads alter the normal functioning of macrophages in a size and dose-dependent manner. Alterations in the oxidative stress, lysosomal and mitochondrial functions were detected, as well as changes in the expression of various surface markers involved in the immune response such as CD11a/b, CD18, CD86, PD-L1, or CD204. For each beads size tested, the alterations were more pronounced for the cell subpopulation that had internalized the highest number of beads. Across beads sizes, the alterations were more pronounced for beads in the supra-micron range than for beads in the sub-micron range. Overall, this means that internalization of high doses of polystyrene favors the emergence of subpopulations of macrophages with an altered phenotype, which may not only be less efficient in their functions but also alter the fine balance of the innate immune system.",

Multiple genetic factors have been linked to lysosomal de-acidification through impairing the vacuolar-type ATPase and ion channels on the organelle membrane. Similar lysosomal abnormalities are also present in sporadic forms of neurodegeneration, although the underlying pathogenic mechanisms are unclear and remain to be investigated. Importantly, recent studies have revealed early occurrence of lysosomal acidification impairment before the onset of neurodegeneration and late-stage pathology. However, there is a lack of methods for organelle pH monitoring in vivo and a dearth of lysosome-acidifying therapeutic agents. Here, we summarize and present evidence for the notion of defective lysosomal acidification as an early indicator of neurodegeneration and urge the critical need for technological advancement in developing tools for lysosomal pH monitoring and detection both in vivo and for clinical applications. We further discuss current preclinical pharmacological agents that modulate lysosomal acidification, including small molecules and nanomedicine, and their potential clinical translation into lysosome-targeting therapies. Both timely detection of lysosomal dysfunction and development of therapeutics that restore lysosomal function represent paradigm shifts in targeting neurodegenerative diseases.",
"37405751": "ID: 37405751\nTitle: Improved imaging and preservation of lysosome dynamics using silver nanoparticle-enhanced fluorescence.\nAbstract: The dynamics of living cells can be studied by live-cell fluorescence microscopy. However, this requires the use of excessive light energy to obtain good signal-to-noise ratio, which can then photobleach fluorochromes, and more worrisomely, lead to phototoxicity. Upon light excitation, noble metal nanoparticles such as silver nanoparticles (AgNPs) generate plasmons, which can then amplify excitation in direct proximity of the nanoparticle's surface and couple to the oscillating dipole of nearby radiating fluorophores, modifying their rate of emission and thus, enhancing their fluorescence. Here, we show that AgNPs fed to cells to accumulate within lysosomes enhanced the fluorescence of lysosome-targeted Alexa488-conjugated dextran, BODIPY-cholesterol, and DQ-BSA. Moreover, AgNP increased the fluorescence of GFP fused to the cytosolic tail of LAMP1, showing that metal enhanced fluorescence can occur across the lysosomal membrane. The inclusion of AgNPs in lysosomes did not disturb lysosomal properties such as lysosomal pH, degradative capacity, autophagy and autophagic flux, and membrane integrity, though AgNP seemed to increase basal lysosome tubulation. Importantly, by using AgNP, we could track lysosome motility with reduced laser power without damaging and altering lysosome dynamics. Overall, AgNP-enhanced fluorescence may be a useful tool to study the dynamics of the endo-lysosomal pathway while minimizing phototoxicity.",
"37488886": "ID: 37488886\nTitle: Recent progress and future directions of the research on nanoplastic-induced neurotoxicity.\nAbstract: Many types of plastic products, including polystyrene, have long been used in commercial and industrial applications. Microplastics and nanoplastics, plastic particles derived from these plastic products, are emerging as environmental pollutants that can pose health risks to a wide variety of living organisms, including humans. However, it is not well understood how microplastics and nanoplastics affect cellular functions and induce stress responses. Humans can be exposed to polystyrene-microplastics and polystyrene-nanoplastics through ingestion, inhalation, or skin contact. Most ingested plastics are excreted from the body, but inhaled plastics may accumulate in the lungs and can even reach the brain via the nose-to-brain route. Small-sized polystyrene-nanoplastics can enter cells by endocytosis, accumulate in the cytoplasm, and cause various cellular stresses, such as inflammation with increased pro-inflammatory cytokine production, oxidative stress with generation of reactive oxygen species, and mitochondrial dysfunction. They induce autophagy activation and autophagosome formation, but autophagic flux may be impaired due to lysosomal dysfunction. Unless permanently exposed to polystyrene-nanoplastics, they can be removed from cells by exocytosis and subsequently restore cellular function. However, neurons are very susceptible to this type of stress, thus even acute exposure can lead to neurodegeneration without recovery. This review focuses specifically on recent advances in research on polystyrene-nanoplastic-induced cytotoxicity and neurotoxicity. Furthermore, in this review, based on mechanistic studies of polystyrene-nanoplastics at the cellular level other than neurons, future directions for overcoming the negative effects of polystyrene-nanoplastics on neurons were suggested.",

This study aimed to investigate the detrimental effects of aggregated CB in the average micron scale on lung tissues and cells in vitro and in vivo. We observed that CB particles induced lung disorders characterized by enhanced expression of inflammation, necrosis, and fibrosis-related factors in vivo. In alveolar epithelial cells, CB exposure resulted in decreased cell viability, induction of cell death, and generation of reactive oxidative species, along with altered expression of proteins associated with lung disorders. Our findings suggested that the damaging effects of CB on the lung involved the targeting of lysosomes. Specifically, CB promoted lysosomal membrane permeabilization, while lysosomal alkalization mitigated the harmfulness of CB on lung cells. Additionally, we explored the protective effects of alkaloids derived from Nelumbinis plumula, with a focus on neferine, against CB-induced lung disorders. In conclusion, these findings contribute to a deeper understanding of the pathophysiological effects of CB particles on the lungs and propose a potential therapeutic approach for pollution-related diseases.",

Autophagy is essential for the innate and adaptive immune responses of DCs, and the transcription factors TFEB and TFE3 are key regulators of autophagic and lysosomal target genes. However, the detrimental alterations of the autophagy-lysosome pathway in As-exposed DCs and the possible coordinating roles of TFEB and TFE3 in the immune dysfunction of this cell are less understood. In this paper, we found that As exposure significantly impaired lysosomal number, lysosomal acidic environment, and lysosomal membrane permeabilization, which might lead to blocked autophagic flux in cultured DCs. Furthermore, our results confirmed that TFEB or TFE3 knockdown exacerbated the disorders of lysosome and the blockade of autophagic flux in As-exposed DCs, and also enhanced the inhibitory expression of co-stimulatory molecules Cd80 and Cd83; adhesion molecule Icam1; cytokines TNF-\u03b1, IL-1\u03b2, and IL-6; chemokine receptor Ccr7; and antigen-presenting molecules MHC II and MHC I. By contrast, overexpression of TFEB or TFE3 partially alleviated the above-mentioned impairment of DCs by inorganic As exposure. In conclusion, these findings reveal a previously unappreciated inhibition of lysosome-mediated degradation and damage of lysosomal membrane integrity leading to dysregulated autophagy and impaired immune functions of DCs by arsenicals, and also suggest TFEB and TFE3 as potential therapeutic targets for ameliorating As toxicity.",

However, fluorescent probes that can concurrently achieve these tasks are not available currently. Herein, we delicately fabricate a robust probe CAQ2 for multiple tasks: illumination of LDs and lysosomes in dual emission colors as well as discriminative visualization of cell apoptosis and autophagy. The probe exhibited both lipophilic and basic properties and displayed different emission colors in neutral and protonated forms; thus, LDs and lysosomes emitted blue and red fluorescence colors, respectively. Because of the lysosomal acidification during autophagy, CAQ2 detected autophagy with evidently enhanced red emission. Because of the lysosomal alkalization during apoptosis, CAQ2 imaged apoptosis with a drastically decreased red fluorescence intensity. With the robust probe, the autophagy under starvation and lipidless conditions was visualized, and the apoptosis induced by H2O2, ultraviolet (UV) irradiation, and rotenone treatment was successfully observed. The efficient detoxification of Na2S against rotenone treatment was successfully revealed.",
"38735599": "ID: 38735599\nTitle: Immunotoxicity of microplastics in fish.\nAbstract: Plastic waste degrades slowly in aquatic environments, transforming into microplastics (MPs) and nanoplastics (NPs), which are subsequently ingested by fish and other aquatic organisms, causing both physical blockages and chemical toxicity. The fish immune system serves as a crucial defense against viruses and pollutants present in water. It is imperative to comprehend the detrimental effects of MPs on the fish immune system and conduct further research on immunological assessments. In this paper, the immune response and immunotoxicity of MPs and its combination with environmental pollutants on fish were reviewed. MPs not only inflict physical harm on the natural defense barriers like fish gills and vital immune organs such as the liver and intestinal tract but also penetrate cells, disrupting intracellular signaling pathways, altering the levels of immune cytokines and gene expression, perturbing immune homeostasis, and ultimately compromising specific immunity. Initially, fish exposed to MPs recruit a significant number of macrophages and T cells while activating lysosomes. Over time, this exposure leads to apoptosis of immune cells, a decline in lysosomal degradation capacity, lysosomal activity, and complement levels. MPs possess a small specific surface area and can efficiently bind with heavy metals, organic pollutants, and viruses, enhancing immune responses. Hence, there is a need for comprehensive studies on the shape, size, additives released from MPs, along with their immunotoxic effects and mechanisms in conjunction with other pollutants and viruses. These studies aim to solidify existing knowledge and delineate future research directions concerning the immunotoxicity of MPs on fish, which has implications for human health.",

Here, we report a series of biodegradable poly(butylene tetrafluorosuccinate-co-succinate) polyesters, comprising a 1,4-butanediol linker and varying ratios of tetrafluorosuccinic acid (TFSA) and succinic acid as components, to engineer lysosome-acidifying nanoparticles (NPs). The synthesized NPs are spherical with diameters of \u2248100 nm and have low polydispersity and good stability. Notably, TFSA NPs, which are composed entirely of TFSA, exhibit the strongest degradation capability and superior acidifying properties. We further reveal significant downregulation of lysosomal vacuolar (H+)-ATPase subunits, which are responsible for maintaining lysosomal acidification, in human T2D pancreatic islets, INS-1 \u03b2-cells under chronic lipotoxic conditions, and pancreatic tissues of high-fat-diet (HFD) mice. Treatment with TFSA NPs restores lysosomal acidification, autophagic function, and mitochondrial activity, thereby improving the pancreatic function in INS-1 cells and HFD mice with lipid overload. Importantly, the administration of TFSA NPs to HFD mice reduces insulin resistance and improves glucose clearance. These findings highlight the therapeutic potential of lysosome-acidifying TFSA NPs for T2D.",

However, antibiotic resistance has become a compelling health issue, leading to H. pylori eradication treatment failure worldwide. Additionally, the powerlessness of antibiotics against biofilms, as well as intracellular H. pylori and the long-term damage of antibiotics to the intestinal microbiota, have also created an urgent demand for antibiotic-free approaches. Herein, we describe an antibiotic-free, multifunctional copper-organic framework (HKUST-1) platform encased in a lipid layer comprising phosphatidic acid (PA), rhamnolipid (RHL), and cholesterol (CHOL), enveloped in chitosan (CS), and loaded in an ascorbyl palmitate (AP) hydrogel: AP@CS@Lip@HKUST-1. This platform targets inflammatory sites where H. pylori aggregates through electrostatic attraction. Then, hydrolysis by matrix metalloproteinases (MMPs) releases CS-encased nanoparticles, disrupting bacterial urease activity and membrane integrity. Additionally, RHL disperses biofilms, while PA promotes lysosomal acidification and activates host autophagy, enabling clearance of intracellular H. pylori. Furthermore, AP@CS@Lip@HKUST-1 alleviates inflammation and enhances mucosal repair through delayed Cu2+ release while preserving the intestinal microbiota. Collectively, this platform presents an advanced therapeutic strategy for eradicating persistent H. pylori infection without inducing drug resistance.",

Although sepsis induces hepatocyte damage, the mechanisms underlying sepsis-related hepatic failure remain unclear. In this study, we demonstrated that the LPS-treated rat hepatocyte cell line Clone 9 not only induced reactive oxygen species (ROS) generation and apoptosis but also increased the expression of the autophagy marker proteins LC3-II and p62, and decreased the expression of intact Lamp2A, a lysosomal membrane protein. Additionally, LPS increased lysosomal membrane permeability and galectin-3 puncta formation, and promoted lysosomal alkalization in Clone 9 cells. Pharmacological inhibition of caspase-8 and cathepsin D (CTSD) suppressed the activation of caspase-3 and rescued the viability of LPS-treated Clone 9 cells. Furthermore, LPS induced CTSD release associated with lysosomal leakage and contributed to caspase-8 activation. Pretreatment with the antioxidant N-acetylcysteine (NAC) not only diminished ROS generation and increased the cell survival rate, but also decreased the expression of activated caspase-8 and caspase-3 and increased the protein level of Lamp2A in LPS-treated Clone 9 cells. These results demonstrate that LPS-induced ROS causes lysosomal membrane permeabilization and lysosomal cell death, which may play a crucial role in hepatic failure in sepsis. Our results may facilitate the development of new strategies for sepsis management.",
"39261719": "ID: 39261719\nTitle: Ammonia-induced lysosomal and mitochondrial damage causes cell death of effector CD8+ T cells.\nAbstract: Ammonia is thought to be a cytotoxin and its increase in the blood impairs cell function. However, whether and how this toxin triggers cell death under pathophysiological conditions remains unclear. Here we show that ammonia induces a distinct form of cell death in effector T cells. We found that rapidly proliferating T cells use glutaminolysis to release ammonia in the mitochondria, which is then translocated to and stored in the lysosomes. Excessive ammonia accumulation increases lysosomal pH and results in the termination of lysosomal ammonia storage and ammonia reflux into mitochondria, leading to mitochondrial damage and cell death, which is characterized by lysosomal alkalization, mitochondrial swelling and impaired autophagic flux. Inhibition of glutaminolysis or blocking lysosomal alkalization prevents ammonia-induced T cell death and improves T cell-based antitumour immunotherapy. These findings identify a distinct form of cell death that differs from previously known mechanisms.",

Due to their excellent filtration capacity, bivalves can easily ingest MNPs, which could be translocated to open circulation system with potential risks. In the present study, the accumulation and elimination of MNPs (200\u00a0nm and 1\u00a0\u00b5m) in the mussel hemolymph serum and hemocytes were firstly quantified, and the differential sensitiveresponses of two subpopulations of hemocytes were then explored by in vivo exposure under environmentally relevant concentration of MNPs (200\u00a0\u00b5g/L). We demonstrated that MNPs were readily translocated into hemolymph serum, but were immediately followed by efficient internalization by hemocytes. Remarkably, concentrations of MNPs in hemolymph were only 0.63 and 0.39 times lower than the ambient exposure concentration. Granulocytes displayed a much higher potential of accumulating MNPs than the agranulocytes. MPs were more readily internalized by granulocytes, with their estimated maximum bioaccumulation factor (BCF) of 0.29\u00a0L/g. Due to the primary function of phagocytic encapsulation of MNPs by granulocytes, lysosome features especially the decline of subsequent lysosome membrane potential could be a potential sensitive biomarker in response to MNPs exposure. Our results provided insights on the bioaccumulation of MNPs at the cellular levels in marine bivalves.",

Targeting lysosomal functions with nanomaterials, such as DNA nanostructures (DNs), represents a rational and systematic way to control cell functionality. Here we present a versatile DNA nanostructure-based platform that can modulate a number of cellular functions depending on the concentration and surface decoration of the nanostructure. Utilizing different peptides for surface functionalization of DNs, we were able to rationally modulate lysosomal activity, which in turn translated into the control of cellular function, ranging from changes in cell morphology to modulation of immune signaling and cell death. Low concentrations of decalysine peptide-coated DNs induced lysosomal acidification, altering the metabolic activity of susceptible cells. In contrast, DNs coated with an aurein-bearing peptide promoted lysosomal alkalization, triggering STING activation. High concentrations of decalysine peptide-coated DNs caused lysosomal swelling, loss of cell-cell contacts, and morphological changes without inducing cell death. Conversely, high concentrations of aurein-coated DNs led to lysosomal rupture and mitochondrial damage, resulting in significant cytotoxicity. Our study holds promise for the rational design of a new generation of versatile DNA-based nanoplatforms that can be used in various biomedical applications, like the development of combinatorial anti-cancer platforms, efficient systems for endolysosomal escape, and nanoplatforms modulating lysosomal pH.",

Consequently, the toxicology of such particles has emerged as a pivotal research interests in recent years. In this study, NP was synthesized successfully with an average particle size of 100\u00a0nm using a emulsion polymerization method as model particles. Following co-incubation of IEC-6 cells with NP for 24-168\u00a0h, a notable inhibition of cell viability and proliferation was observed. The significant activation of autophagy and a concomitant blockage of autophagic flux in IEC-6 cells after 24-72\u00a0h of co-incubation with NP were unveiled by transmission electron microscopy, western blotting, and double-fluorescent autophagy analysis. A significant increase in the number of lysosomes and an increase in the expression of hydrolase CTSB were detected, indicating dysregulation of lysosomal function. The subsequent transcriptomic and metabolomics analyses, coupled with the observation of activated lysosomes and the RIPK1-RIPK3-MLKL/PYGL pathway, led us to posit that the blockade of autophagy and lysosomal dysfunction, culminating in lysosomal membrane permeabilization (LMP) induced necroptosis, constitutes one of the mechanisms contributing to the cytotoxicity of NP.

Nevertheless, their toxicity mechanisms in soil invertebrates remain unclear. This study investigated the impact of polystyrene NPs on Eisenia fetida (Savigny, 1826) immune cells, focusing on oxidative stress, immune responses, apoptosis, and necrosis. Results showed that 100 nm NPs were internalized into the cells, causing cytotoxicity. NPs were observed to inhibit cell viability by increasing reactive oxygen species, decreasing the levels of antioxidants (e.g., superoxide dismutase, catalase, and glutathione), and inducing lipid peroxidation and DNA oxidation. Additionally, assays on neutral red retention time, lysozyme activity, and Ca2\u207a levels demonstrated that NPs resulted in a loss of lysosomal membrane stability and a reduction in immune resistance. The depolarization of the mitochondrial membrane potential and the results of the apoptosis assays confirmed that the NPs induced the onset of early apoptosis.

Parkinson's disease (PD) is a major neurological disorder clinically characterized by intracellular Lewy-body inclusions and dopaminergic neuronal death. These pathological hallmarks of PD, according to Braak's hypothesis, are mediated by the afferent propagation of \u03b1 synuclein (\u03b1S) via the enteric nervous system, or the so-called gut-brain axis. Here we first examined the effect of enteric exposure to polystyrene nanoplastics on the peripheral and central pathogenesis of A53T, a representative \u03b1S mutant. Specifically, the polystyrene nanoplastics accelerated the amyloid aggregation of A53T \u03b1S, which subsequently elevated the in vitro production of glial activation biomarkers, cytokines, and reactive oxygen species and compromised mitochondrial and lysosomal membrane integrity, further shifting cellular metabolite profiles in association with PD pathophysiology. In vivo, coadministration of the polystyrene nanoplastics and A53T \u03b1S facilitated their synergistic gut-to-brain transmission in mice, leading to progressive impairment of physical and motor skills in resemblance to characteristic PD symptoms.

Therefore, accurate monitoring of lysosomal pH changes in living cells is essential for the diagnosis and treatment of such diseases, despite the significant challenges involved. In this study, we synthesized a pH-dependent fluorescent probe, B26, which comprises 1,8-naphthalimide as the fluorescent chromophore, an N-(2-hydroxyethyl) piperazine group for lysosome targeting, and a hydroxyethyl group to increase solubility and regulate pKa. B26 demonstrated high sensitivity, selectivity, and reversibility in response to H+, and exhibited a remarkable 98-fold increase in fluorescence intensity between pH 2.0 and pH 11.0, with a pKa value of 7.0, highlighting its \"turn-on\" fluorescence property. Density functional theory calculations and 1H NMR titration revealed that the pH-sensing mechanism of B26 relies on the inhibition of photoinduced electron transfer from the N-(2-hydroxyethyl) piperazine group to the naphthalimide moiety under acidic conditions. Importantly, B26 effectively labeled lysosomes and displayed significant sensitivity to pH changes, facilitating the quantitative detection of pH shifts during lysosomal alkalization in living cells due to its elevated pKa. These findings suggest that B26 successfully addresses the limitations of existing lysosomal pH probes, particularly in detecting pH changes within the near-neutral range. Furthermore, both the zebrafish model and subcutaneous imaging support the application of B26 in in vivo settings. Given its exceptional properties, B26 holds enormous potential for the research and diagnosis of pH-related diseases.",

Cell viability, oxidative stress, mitochondrial dynamics, lysosomal degradation processes, autophagy, inflammation/oxidative responses and consequences for placental endocrine and angiogenic functions were assessed. PS-NP size determines their internalization rate and their behavior in trophoblasts. Indeed, PS-NP20 are more rapidly translocated, and accumulated in lysosomes as shown by confocal and TEM imaging. They induce higher cytotoxicity than PS-NP100, as early as 1\u202f\u00b5g\u202fmL-1 (p\u202f<\u202f0.05).

Astrocytes also regulate neuronal functions and survival by modulating myelination and degradation of pathological toxic protein aggregates. Astrocytes have recently been proposed to possess both autophagic activity and active phagocytic capability which largely depend on sufficiently acidified lysosomes for complete degradation of cellular cargos. Defective lysosomal acidification in astrocytes impairs their autophagic and phagocytic functions, resulting in the accumulation of cellular debris, excessive myelin and lipids, and toxic protein aggregates, which ultimately contributes to the propagation of neuroinflammation and neurodegenerative pathology. Restoration of lysosomal acidification in impaired astrocytes represent new neuroprotective strategy and therapeutic direction. In this review, we summarize pathogenic factors, including neuroinflammatory signaling, metabolic stressors, myelin and lipid mediated toxicity, and toxic protein aggregates, that contribute to lysosomal acidification impairment and associated autophagic and phagocytic dysfunction in astrocytes. We discuss the role of lysosomal acidification dysfunction in astrocyte-mediated neuroinflammation primarily in the context of neurodegenerative diseases along with other brain injuries. We then highlight re-acidification of impaired lysosomes as a therapeutic strategy to restore autophagic and phagocytic functions as well as lysosomal degradative capacity in astrocytes. We conclude by providing future perspectives on the role of astrocytes as phagocytes and their crosstalk with other CNS cells to impart neurodegenerative or neuroprotective effects.",

According to statistics, diabetic patients have exceeded 463 million worldwide, and the prevalence of hyperlipidemia is also continuously rising. These glycolipid metabolic diseases not only significantly increase the risk of complications such as cardiovascular disease, stroke, and kidney disease but also impose a huge economic burden on the global healthcare system. Despite the continuous emergence of treatment methods for glucose and lipid metabolic diseases with the advancement of research technology, existing therapies still face many challenges. In recent years, the rapid development of nanotechnology has injected new vitality into the medical field. As an emerging research field, nanomedicine has attracted much attention for its application prospects in the treatment of glycolipid metabolic diseases. Nanotechnology is expected to provide more precise and efficient solutions for the treatment of these diseases, thereby reducing global health and economic pressures. The objective of this article is to comprehensively review the relationship between nanotechnology and glucose and lipid metabolism. We have carried out a series of literature searches, focusing on glycolipid effects and toxicity of nano-materials. Nanoparticles as drug carriers or nanoparticles enhance bioavailability and activity. Nano-material-based optical reporters aid in detecting lysosome lipid content, facilitating treatment and drug development for glucose and lipid metabolism disorders.

However, there is a pressing need for the development of drugs that can safely and effectively modulate the pH of cancerous lysosomes in a controlled manner. In this study, we propose a novel strategy for lysosomal alkalinization triggered by piezoelectricity. Our findings indicate that the electrons generated by (BaTiO3/Zr/Ca) BCZT under sonication effectively alkalinize the lysosomes. Molecular dynamics simulations further demonstrate that alterations in lysosomal pH lead to modifications in the conformation of V-ATPase (proton pump), enhancing its interaction with sodium ions while partially excluding hydrogen ions from entering the lysosomes. This mechanism helps maintain lysosomal alkalization, resulting in reduced hydrolase activity and preventing the degradation of proteins and damaged organelles. The accumulation of nanoparticles within the lysosomes causes swelling and gradual destruction of the lysosomal membrane. Consequently, this lysosomal dysfunction hampers the fusion with autophagosomes, inhibiting autophagy in tumor cells and promoting apoptosis in various tumor types. Our strategy significantly inhibited tumor volume growth in mice during animal studies. In conclusion, our piezoelectric-triggered lysosomal alkalinization strategy holds promise for innovative breakthroughs in the treatment of multiple cancers.",

Therefore the development of novel strategies to efficaciously control infectious inflammation is urgently required. Nuclear factor-\u03baB (NF-\u03baB) as the central activator of pro-inflammatory genes plays a pivotal role in infectious inflammation. Here, nanoscale chirality was designed to modulate the inflammatory response through enantiomer-dependent blockade of the NF-\u03baB signaling pathway. Chiral gold nanoparticles (AuNPs) with good cytocompatibility were prepared through a one-pot seedless method under wild conditions, showing efficacious alleviation of lipopolysaccharide (LPS)-induced inflammation in vitro and in vivo only by AuNPs with levorotatory chirality (L-AuNPs) rather than the dextrorotatory enantiomer (D-AuNPs). Mechanism investigation elucidated that lysosomal acidification of macrophages was inhibited through a high cellular uptake of L-AuNPs due to their weak interaction energy with cell membranes. Accordingly, the NF-\u03baB rather than mitogen-activated protein kinase pathway was blocked by L-AuNPs through the selective inhibition of p65 phosphorylation, wherein the nuclear translocation of p65 was simultaneously depressed, so the secretion of pro-inflammatory mediators was reduced significantly. This study suggests that imparting chirality to nanoparticles can provide a novel protocol to efficaciously modulate health risks arising from infectious inflammation by improving the uptake of nanoparticles with anti-inflammatory activity.",

However, the long-term adverse effects of nanoplastics on the female reproductive system remain unclear. Polystyrene nanoplastics (PS-NPs; 50 nm diameter) were selected as representative nanosized plastic particles to investigate the potential effects of subchronic prenatal and gestational exposure via drinking water on placental development in ICR (CD-1) mice. Maternal exposure to 10 mg/L PS-NPs induced an increase in fetal resorption rate and significantly increased fetal weight. Further observation of the placental morphology showed that PS-NPs exposure led to an aberrant placental structure and damaged the trophoblast cells. At the cellular level, PS-NPs exposure promoted the proliferation, migration, and invasion of HTR-8/SVneo cells. Mechanistically, transcriptomic and proteomic analyses revealed that PS-NPs triggered placental calcium disturbances and upregulated the Stam2 expression in mice. STAM2 induced by PS-NPs mediates the disruption of trophoblastic calcium homeostasis and regulates cell functions by disturbing the lysosomal degradation of the calcium channel protein IP3R3 and promoting intracellular calcium inflow by increasing the level of TRPV6 in HTR-8/SVneo cells. Therefore, our results indicated that trophoblastic calcium dyshomeostasis is the main mechanism by which subchronic PS-NPs exposure induces abnormal placental development. These findings reveal a link between subchronic PS-NPs exposure and placental damage and elucidate the underlying molecular mechanism, providing evidence for environmental triggers of adverse pregnancy and highlighting the risk of plastic products to pregnant women.",

While previous studies have indicated that MNPs can cantribute to cardiac dysfunction, there is limited systematic investigation into how MNPs exposure affects various organelles. This study focuses on polyvinyl chloride nanoparticles (PVC NPs), one of the most common and persistent plastic pollutants in the environment. Our findings reveal that PVC NPs engage in organelle-specific interactions, predominantly accumulating in the lysosomes and mitochondria of cardiomyocytes. This targeted accumulation results in substantial disruptions to lysosomal autophagic flux and mitochondrial energy metabolism. These results offer new insights into the organelle-specific mechanisms behind PVC NP-induced cardiotoxicity, highlighting the distinct risks associated with this widespread environmental contaminant.",

This study provides the first evidence of NPs intercellular transfer in the hemocytes of green mussels (Perna viridis), which subsequently activated the immunomodulation process. NPs were predominantly internalized by granulocytes, with a portion being translocated and deposited in lysosomes, whereas those retained in endosomes were subsequently transferred to new hemocytes (mainly granulocytes). The transfer direction was driven by the intracellular NP concentration gradients. Transfer kinetics was size-dependent, with smaller-sized NPs exhibiting greater potential but a lower rate, primarily due to their specific extracellular vesicle-mediated transfer pathway. Tunneling nanotubes provided the most efficient pathway for the intercellular transfer of NPs, as their continuous membrane structure allowed direct substance exchange. Crucially, NP redistribution was accompanied by a gradient-driven transfer of mitochondria to injured hemocytes. This process alleviated stress on the overburdened hemocytes and regulated reactive oxygen species production, subsequently enhancing phagocytic activity and promoting immune responses. These findings underscore that NPs exhibit far more active behavior in the immune system than previously understood and provide new insights into how immune cells maintain the health of marine organisms in the face of NP challenges.",

Here, we explored the therapeutic potential of two charged dendrimers, dendritic polyglycerol sulfate (dPGS) and dendritic polyglycerol amine (dPGA), in the context of glioblastoma multiforme (GBM). Docosahexaenoic acid (DHA) has shown potential in GBM. We therefore examined dPGS and dPGA effects alone and in combination with DHA. Using 2D cell models and 3D tumoroids, we showed that DHA with dPGA reduced tumor integrity and cell viability. dPGS reduced oxidative stress, whereas dPGA reduced lysosomal acidification, contributing to cellular dysfunction. Both dendrimers influence the interaction between high mobility group box 1 (HMGB1) and the receptor for advanced glycation end products (RAGE). The surfaces of the HMGB1-RAGE complex provide binding sites for interactions of charged molecules like dPGS and dPGA, suggesting the contribution of these interactions to cytotoxicity. In summary, our findings show that combining DHA with charged dendrimers (dPGS and dPGA) enhances GBM cytotoxicity through several mechanisms, involving lysosomal alkalinization, lipid peroxidation and modulation of the HMGB1-RAGE complex.",

Its success depends on the ability to efficiently and specifically deliver therapeutic nucleic acids (NAs) into target cells. Although viral or chemical carriers have been used in pioneering applications, safety concerns, and variable delivery efficiencies have prompted the search for alternative delivery vehicles. Light-mediated strategies have gained particular interest due to their biocompatibility and ability to improve the intracellular delivery efficiency.

However, many synthetic systems rely on heterogeneous mixtures, lack biodegradability, and pose toxicity concerns. Here, we introduce a peptide dendron single-molecule transfection reagent that enables targeted DNA delivery via pH-responsive, degradable nanoparticles with minimal toxicity. Peptide dendrons for intracellular delivery (PDIDs) incorporate ionizable non-natural amino acids for DNA binding and pH sensitivity. PDIDs formed stable nanoparticles that released DNA upon lysosomal acidification, facilitating cytoplasmic entry and subsequent gene expression. Rationally designed triamino acid blocks promoted protease degradation, reducing toxicity in preclinical models. Targeting ligands further enhanced the transfection efficiency by increasing cell uptake. In a lung metastasis model, targeted PDID-DNA nanoparticles selectively delivered therapeutic gene cargo to the lung, reducing tumor burden and extending survival. This platform demonstrates the potential to integrate natural and non-natural peptide features to enable safe and efficient DNA delivery in vivo.",

Its silk glands are responsible for the synthesis and secretion of silk proteins. The naked pupa (Nd), a fibroin heavy chain mutant strain of silkworm, was found to exhibit severe atrophy, degeneration of the posterior silk gland (PSG), and abnormal secretion of fibroin proteins, thereby producing little or no silk. Here, we found that the autophagic marker Atg8-PE was upregulated through the target of rapamycin complex 1 signaling pathway in Nd. However, as autophagy substrates, SQSTM1/p62 and ubiquitinated protein levels increased in Nd. Furthermore, treatment with BafA1 showed no effect on the protein levels of SQSTM1/p62, indicating impaired autophagic flux in Nd. Abnormal acidification of lysosomes was further detected, which resulted in a decreased proportion of matured CtsL1 (cathepsin L1). Thus, the substrate in autolysosomes cannot be degraded within a rapid time frame, resulting in the accumulation of protein aggregates, which cause atrophy and degeneration of the PSG. We also found that acidic nanoparticles rescued lysosomal acidification and relieved the degenerative changes of Nd-PSG. The findings of this study suggest that the Nd mutant silkworm can be used as an animal model for studying protein aggregation diseases.Abbreviations: AD: Alzheimer disease; aNP: acidic nanoparticle; APP: amyloid beta precursor protein; Atg8: autophagy related 8; BACE1: beta-secretase 1; BafA1: bafilomycin A1; CtsL1: cathepsin L1; CRY: crystallin; ER: endoplasmic reticulum; FibH: fibroin heavy chain; FibL: fibroin light chain; FUS: FUS RNA binding protein; HD: Huntington disease; HRP: horseradish peroxidase; Nd: naked pupa; OSBPL2: oxysterol binding protein like 2; PD: Parkinson disease; PE: phosphatidylethanolamine; p-EIF4EBP: phosphorylated eukaryotic initiation factor 4E binding protein; PROM1: prominin 1; p-RPS6KB: phosphorylated ribosomal protein S6 kinase B; PSEN: presenilin; PSG: posterior silk gland; SDS-PAGE: sodium dodecyl sulfate-polyacrylamide gel electrophoresis; SEM: standard error of the mean; SOD1: superoxide dismutase 1; SQSTM1/p62: sequestosome 1; TARDBP: TAR DNA binding protein; TORC1: target of rapamycin complex 1; UBQLN2: ubiquilin 2; V-ATPase: vacuolar-type ATPase.",

However, the tunability of the crystallite size of aluminum-based MOFs (Al-MOFs) is still a long-standing challenge. In this study, we present systematic high-throughput investigations elucidating the synergistic effects of different mono- and dicarboxylic acids (acetic acid, malonic acid, and oxalic acid) as coordination modulators and NaOH as a pH modulator on the crystal size of various Al-MOFs, with a focus on Al-MIL-53-NO2. By varying the type and amount of coordination modulators, we successfully extended the range of achievable particle sizes to nanoparticles as well as large crystals (dmax\u00a0\u2248\u00a0100\u00a0nm\u00a0-\u00a0800\u00a0\u00b5m) compared to traditional synthesis methods using only coordination modulators. Thus, large crystals as well as nanoparticles of different Al-MOFs could be obtained by simply varying the molar ratio of the different modulators.

Environmental toxins are considered the main etiological factor. The increasing use of polystyrene nanoparticles (PS-NPs) has raised concerns about their potential neurotoxic effects in PD. This study aimed to investigate the impact of PS-NPs on the onset and progression of PD and the underlying mechanisms. The breach of the blood-brain barrier (BBB) by PS-NPs was assessed using bioluminescence imaging, fluorescence observation, Pyrolysis-Gas Chromatography-Mass Spectrometry (Py-GCMs), transmission electron microscope (TEM), and Evans blue staining. To evaluate the potential promotion of PD by PS-NPs, a 30-day repeated oral administration study was conducted in vivo, during which behavioral changes and alterations in dopaminergic neurons in the substantia nigra were assessed. In vitro cytotoxicity assays were performed following PS-NPs intervention. Molecular biology techniques, including Western blotting and immunofluorescence, were employed to analyze proteins related to pyroptosis and autophagy-lysosomal pathway in both in vivo and in vitro settings. Additionally, proteomic sequencing was utilized to identify the upstream regulator of the autophagy-lysosomal pathway (ALP), and the effects of modulating this target protein on the ALP-pyroptosis pathway were analyzed. Bioluminescence imaging and Py-GCMs confirmed that PS-NPs entered the brain within 1.5\u00a0h. Evans blue staining and TEM showed PS-NPs damaged the BBB. The 30-day oral toxicity revealed that PS-NPs exacerbated behavioral abnormalities and caused dopaminergic neuron loss. Western blotting and immunofluorescence indicated that PS-NPs induced pyroptosis, disrupted autophagic flux, and lowered protein levels involved in autophagosome-lysosome fusion, both in vivo and in vitro. Furthermore, PS-NPs activated the mechanistic target of rapamycin (mTOR) and inhibited the nuclear translocation of Transcription Factor EB (TFEB). Proteomic sequencing identified a deficit of Tuberous Sclerosis Complex (TSC) 2 protein within the mTOR pathway. Immuno-coprecipitation and Coomassie Blue Fast Staining revealed that PS-NPs bound to TSC2 protein, causing disassembly of TSC1-TSC2 complex. These findings underscore how PS-NPs accelerated PD onset and progression by disrupting autophagosome-lysosome fusion through TSC2-mTOR-TFEB axis, which triggered protein degradation disorders and pyroptosis in dopaminergic neurons. The molecular mechanisms could inform environmental safety regulations concerning nanoplastics and inspire therapeutic strategies for PD.",

A Comprehensive Review of the Literature.\nAbstract: Inflammation is a protective response of the body, but when excessive or prolonged, it can contribute to disease progression and tissue damage. Identifying more effective and less toxic drugs for treating both acute and chronic inflammatory diseases is a major challenge. Organelle-targeting strategies, which deliver drugs directly to specific organelles, offer a promising solution by improving treatment efficiency and minimizing toxic effects on healthy cells. However, despite the potential of organelles as therapeutic targets, precise targeting remains challenging. This review systematically summarizes organelle-targeting nanodelivery strategies for major organelles-mitochondria, the endoplasmic reticulum, lysosomes, and the Golgi apparatus-and the research progress in evaluating the potential of these strategies for treating inflammation-related diseases. This study focuses on the applications of these strategies for the treatment of sepsis, inflammatory bowel disease, atherosclerosis, and osteoarthritis.

Cancer stem cells (CSCs), a critical subset within tumor tissues, exacerbate this acidity through overexpression of pH-regulating proteins such as carbonic anhydrase IX (CA9), which plays a pivotal role in maintaining pH homeostasis, contributes to immune suppression, and sustains CSC stemness and proliferation. In this study, we designed CA9 inhibitor (CAi) coupled hydroxyethyl starch-based nanoparticles (CHHD-Cu NPs) that integrate doxorubicin (DOX) mediated chemotherapy with copper ions (Cu2+) mediated chemodynamic therapy to target and eliminate CA9-expressing CSCs. Upon administration, CHHD-Cu NPs bind to CA9 and disrupt pH regulation, thereby lowering intracellular pH and raising extracellular pH. This pH modulation enhances intracellular releases of DOX and Cu2+ and alleviates extracellular acidity to boost effector T cells infiltration and activity. Our rationally designed CHHD-Cu NPs eliminate CSCs in two ways: firstly, by robust intracellular DOX- and copper-induced cytotoxicity, and secondly, via pH modulation-mediated activation of anti-tumor immunity. Our strategy offers novel approaches for treatment of immunosuppressive solid tumors.",

However, most existing research has focused on single exposure, which is not consistent with the actual exposure circumstance. In this study, single and co-exposure animal model were established. C57/BL6J mice were exposed to corn oil, 20\u00a0mg/kg PS-MPs, 200\u00a0mg/kg DEHP and PS-MPs\u00a0+\u00a0DEHP for 28 days. The HE staining showed more serious seminiferous epithelium disorganization in co-exposed mice, indicating that PS-MPs and DEHP co-exposure could aggravate testicular injury. Compared with control group, integrative analysis of transcriptomics and proteomics revealed that PPAR\u03b3 pathway played a crucial role in PS-MPs and DEHP co-exposure induced testis injury. In vitro, spermatocytes (GC-2) and leydig cells (TM3) were exposed to 50\u00a0\u03bcM MEHP, 10\u00a0mg/L PS-MPs and PS-MPs\u00a0+\u00a0MEHP for 48\u00a0h. Though PS-MPs and MEHP single exposure also triggered oxidative stress and PPAR pathway, the protein levels showed more remarkable difference in co-exposure group. Furthermore, co-exposure to PS-MPs and MEHP induced lysosomal membrane permeabilization (LMP), which significantly impaired lysosomal-mediated lipid degradation, thereby exacerbating lipid metabolism dysfunction in testicular cells. Treatment with N-Acetylcysteine (NAC) and knockdown of fatty acid-binding protein (FABP4) restored lipophagy flux and reduced lipid droplets deposition. Overall, co-exposure of PS-MPs and DEHP has synergistic toxic effect, inducing oxidative stress, PPAR\u03b3 activation and lipophagy blockage, finally resulting in unbalanced lipid metabolism and testicular damage.",

After 24\u202fh, most exceeded 5000\u202fnm, except NP500 (1473\u202fnm). In GMB, only positively charged A-NP50 aggregated substantially (> 5000\u202fnm), while negatively charged PSNPs remained stable. All PSNPs exhibited higher deposition rates in ALF than GMB. Higher particle concentrations promoted aggregation for all PSNPs in ALF, but only A-NP50 in GMB. Opposite pH effects on A-NP50 and NP50 were observed. Na2HPO4, NaHCO3, sodium pyruvate, and trisodium citrate promoted A-NP50 aggregation via electrostatic interactions and adsorption. BSA modulated aggregation in a concentration- and fluid-dependent manner: low levels (< 260\u202fmg/L) enhanced NP50 aggregation via charge screening, while higher levels stabilized it via steric hindrance. For A-NP50, BSA consistently reduced aggregation. These findings provide insights into NP transport and health risks in pulmonary environments.",

However, most siRNA can't exert a therapeutic effect due to a lack of targeting to tumor cells and entrapment in lysosomes upon administration. To address the challenges associated with siRNA delivery, a delivery system was developed using zinc oxide nanoparticles (ZnO NPs) coated with cancer cell membranes. ZnO nanoparticles (ZnO NPs) have been recognized as effective pH-responsive nanoparticles and are widely used in the development of pH-responsive drug delivery systems. The ZnO NPs were combined with chitosan to encapsulate siRNA, allowing for dissolution in acidic lysosomes and the subsequent release of siRNA and chitosan complexes. The dissolution of ZnO NPs would also disrupt lysosomes, facilitating the escape of siRNA and enhancing its gene silencing effect. However, the chitosan and ZnO NPs nano-complexes (CS/ZnO@siRNA) were unstable in solution and lacked a specific targeting effect for tumor cells. Thus, a homologous cancer cell membrane was coated onto the nanoparticles, which has been shown to be an effective strategy for enhancing their stability and targeting capabilities. Moreover, ZnO NPs not only dissolve in acidic lysosomes to enhance the efficacy of siRNA but also elevate oxidative stress levels in cells, leading to the induction of cellular apoptosis. It was demonstrated both in vitro and in vivo that the ZnO NPs could synergistically combine with the anti-tumor siRNA (siSurvivin) to inhibit the growth of the 4T1 tumor. Altogether, the developed drug delivery system (CCM-CS/ZnO@siSurvivin) offers a new strategy for enhancing the therapeutic effect of siRNA, while synergistically inhibiting tumor growth.

This study investigated the effects of polystyrene (PS) NPs on steatosis and fatty liver disease. PS-NP oral administration, in conjunction with a high-fat diet (HFD), synergistically exacerbated the symptoms of steatosis in mice, leading to increased alanine transaminase, aspartate aminotransferase, and cholesterol levels; no effects were observed with PS-NPs on a normal chow diet. Transcriptome analysis unveiled that PS-NPs interfered with actin organization, cell-cell adhesion, PPAR signaling, and lipid metabolism. In HepaRG cells, PS-NPs rapidly entered by inducing actin rearrangement, resulting in the formation of numerous small cytoplasmic vesicles. This treatment led to an augmented number of acidic organelles, leading to development and buildup of large vacuoles, indicative of enlarged pre-lysosomal and lysosomal compartments. PS-NP exposure hampered p62 degradation, leading to LC3B accumulation and decreased cathepsin B and D activity. Additionally, PS-NP exposure resulted in accumulation of lipid droplets and elevated expression of lipogenesis-, transport-, and storage-related genes. These findings suggest that excessive endocytosis driven by PS-NPs worsens MASLD in HFD through accumulation of lysosomes and large vacuoles with reduced cathepsin activity.",

Here, we report a nonendocytic approach for preferential and rapid mitochondrial delivery of molecular drugs using a designed nanocarrier. The drug-loaded nanocarrier rapidly enters into the cell via temporary membrane pore formation, releases molecular drugs into cytosol without any vesicular entrapment, and labels mitochondria within 5 min. In contrast, control nanocarrier-based delivery of the same molecule via endocytic root leads to lysosomal trafficking. This result demonstrates the advantage of the nonendocytic approach for efficient mitochondrial targeting of drugs with potential therapeutic advantages.",

The surface morphology of GINACNPs@MNs confirmed successful development of pyramidal-shaped sharp, projections. The ATR-FTIR, DSC, analysis displayed the drug-polymeric interactions, and proved that the bioactive remained in the amorphous state in the microneedle matrix.

In the present experimental investigation, a double pass SAC is fabricated, and the absorber plate is coated using activated carbon derived from the waste tea dust to augment the energy absorption rate. The thermal performance of the proposed system is compared by flowing the air through the rectangular cavity of the double pass SAC at different flow rates, namely 0.6, 1.2, and 1.8 kg/min. The output parameters, such as absorber temperature, heat transfer coefficient, air temperature leaving the duct, and thermal efficiency of the proposed double pass SAC, are compared with the conventional double pass SAC with black paint coating. The experimental studies revealed that the temperature of the absorber, air temperature leaving the duct, and thermal efficiencies are improved using activated carbon nanoparticles derived from the waste tea dust compared to the double pass SAC with black paint as a surface coating. Results demonstrated significant improvements: the activated carbon nanoparticle (ACNP)-coated absorber achieved an average thermal efficiency of 96.2% (vs. 77.8% for conventional) at 1.8 kg/min, with efficiency enhancements of 10.05-19.12% across flow rates. The exit air temperature and temperature difference between inlet/outlet increased by up to 10.71%, attributed to the ACNPs' superior solar absorption and heat transfer properties.

Transcriptome sequencing and analysis was utilized to confirm the altered pathways and differentially expression genes associated with ALP. Transmission electron microscopy observation was conducted to find the ultrastructure differences between the Nurr1 knockdown cells and the controls. The expression of LC3B and the colocalization of LC3B and Lamp1 were assessed. Lysosomal acidity in the Nurr1 knockdown cells and the controls was measured. The expression of lysosomal proteins (Lamp 1/2, CTSD, and GBA) was determined in vitro and in vivo in the Nurr1-deficient models. Dual-luciferase reporter gene assay was performed to detect the transcriptional activity of GBA. The key lysosomal proteins (Lamp 1/2 and CTSD) were assessed after GBA overexpression. Twenty-two terms and 45 differentially expression genes associated with ALP were identified by transcriptome analysis. Knockdown of Nurr1 induced intracellular aggregation of autophagosomes, increased endogenous expression of LC3B II and elevated colocalization of exogenous GFP-LC3B with Lamp1. Lysosome dysfunction has been implicated with lysosomal alkalization and deprived level of lysosomal marker proteins with Nurr1 deficiency. GBA was transcriptionally downregulated by Nurr1 and Nurr1 deficiency-triggered lysosomal dysfunction were attenuated by GBA overexpression in the Nurr1 knockdown cells. Our study provided the first experimental evidence that Nurr1 deficiency induced lysosomal dysfunction by alkalizing the lumen of lysosomes and downregulating the key lysosomal protein (Lamp1, CTSD, and Lamp2) expression in vivo and in vitro. Defective lysosomal function compromised lysosomal mediated autophagic vesicle clearance. Mechanistically, Nurr1 transcriptionally regulated GBA expression, which in turn governed lysosomal marker protein homeostasis through a GBA-dependent axis. This study illuminated the involvement of Nurr1 in the ALP and the interaction between PD-related genes in the pathogenesis of PD.",

However, whether NPs induce renal fibrosis remains contentious, and the reversibility of NPs-triggered nephrotoxicity has rarely been reported. This study investigated the role of lysosomes in renal fibrosis induced by low-level polystyrene (PS) NPs with particle sizes of 100 and 500 nm (PS100 and PS500) in mice using Masson staining, immunohistochemistry, Western blotting, fluorescence imaging, and other techniques. The results showed that PS100 induced more pronounced renal fibrosis than PS500. Mechanistically, PS NPs promoted autophagosome formation accompanied by the inhibition of autophagic degradation. Moreover, PS NPs impaired lysosomal degradation function, evidenced by reduced CTSB and CTSD protein levels. This impairment blocked autophagic flux, thereby inducing renal fibrosis, which was further confirmed by in vitro results. Notably, lysosomal exocytosis plays a crucial role in the clearance of NPs from mouse kidneys through activating Mcoln1 expression, which contributes to restoring autophagic flux and alleviating renal fibrosis during recovery. Collectively, our findings provide the first evidence that lysosomes serve dual functions in the persistence and reversibility of NPs-induced nephrotoxicity, which could be valuable for the intervention and mitigation of kidney damage resulting from environmental NPs exposure.",

Melanosomes coexist with lysosomes; thus, melanocytes employ trafficking machineries that possess cell-type-specific functions to ensure correct cargo delivery to either the endolysosomal system or maturing melanosomes. Mutations in some of the protein complexes required for melanogenic cargo delivery, such as biogenesis of lysosome-related organelles complex 1 (BLOC-1), result in hypopigmentation due to mistrafficking of cargo to endolysosomes. We show that hypopigmented BLOC-1-deficient melanocytes retain melanogenic capacity that can be enhanced by treatment with cyclic adenosine monophosphate (cAMP)-elevating agents despite the mislocalization of melanogenic proteins. The melanin formed in BLOC-1-deficient melanocytes is not generated in melanosomes but rather within late endosomes/lysosomes to which some cargoes mislocalize. Although these organelles generally are acidic, a cohort of late endosomes/lysosomes have a sufficiently neutral pH to facilitate melanogenesis, perhaps due to mislocalized melanosomal transporters and melanogenic enzymes. Modulation of the pH of late endosomes/lysosomes by genetic manipulation or via treatment with lysosomotropic agents significantly enhances the melanin content of BLOC-1-deficient melanocytes. Our data suggest that upregulated expression of mistargeted cargoes leads to both increased tyrosinase expression and subsequent activity due to pH modulation facilitating the reprogramming of a subset of endolysosomes to replicate some functions of lysosome-related organelles.",

This study investigates the toxicological effects of spherical PSMPs (<0.50\u202f\u00b5m) on Raw 264.7 murine macrophages, critical immune cells that actively internalize foreign materials. At exposure concentrations ranging from 50 to 500\u202f\u00b5g/mL, PSMPs were rapidly internalized within 2\u202fh, with accumulation increasing over time. Notably, high-dose exposure (500\u202f\u00b5g/mL) resulted in significant mitochondrial membrane damage, lysosomal dysfunction, elevated reactive oxygen species (ROS) levels, and lipid peroxidation. These cellular stress responses were accompanied by increased levels of LDH and SOD, as well as the induction of apoptosis and cellular senescence. The findings show that PSMPs disrupt mitochondrial function and contribute to senescence responses, ultimately compromising immune cell viability and function. This study provides new insight into the intracellular fate and toxicity of environmentally relevant PSMPs and emphasizes the need for urgent evaluation of plastic pollution's impact on human health.",

However, the antibacterial efficacy of nanozymes is constrained by their dependence on hydrogen peroxide (H2O2). In this study, a glucose-activatable nanoreactor (FCSGP NPs) with high antimicrobial efficiency and drug loading ability is designed to enhance the anti-infection effects in diabetic wound healing. Under hyperglycemic conditions, this nanoreactor initiates a sequential cascade reaction by consuming glucose, thereby amplifying the anti-infective effects. The glucose oxidase (GOx)-mediated glucose oxidation cascade produces both H2O2 (for the Fenton reaction) and gluconic acid (for pH modulation), synergistically enhancing chemodynamic therapy (CDT). The resulting acidic microenvironment accelerates the FCSGP nanoreactor degradation, triggering the glutathione (GSH)-induced release of Fe and Cu ions, which subsequently catalyze a Fenton-like reaction with H2O2 to generate a highly reactive hydroxyl radical (\u2022OH). Furthermore, the FCS-mediated photothermal (PTT) effect induces localized hyperthermia, which simultaneously enhances the GOx enzymatic activity and enables synergistic PTT-CDT. This combined action eradicates biofilm-associated infections in the absence of exogenous H2O2 while accelerating diabetic wound healing. By leveraging these synergistic cascade reactions, this endogenous enzyme-based strategy offers a promising platform for enhancing diabetic wound healing.",

This study evaluates the efficacy of thermostable ZnO NPs/AA nanocomposites in suppressing S.mutans acid production, disrupting its biofilm matrix, and strengthening enamel integrity, with an emphasis on its potential as a novel dental healthcare material. This study encompassed the synthesis of zinc oxide nanoparticles functionalized with Asiatic acid (ZnO NPs/AA) using a co-precipitation method. The physicochemical properties of ZnO NPs/AA were characterized using FE-SEM with EDS, XRD, FT-IR, and UV-DRS, confirming structural integrity and functional modifications. Thermal stability was assessed via TGA and DSC, demonstrating robust performance suitable for biomedical applications. The antibacterial activity, anti-biofilm efficacy of ZnO NPs/AA including, extracellular polymeric substance inhibition, and acidogenic activity modulation were evaluated through microdilution methods, biofilm biomass quantification assays, Congo red binding studies, and pH analysis. In ex-vivo studies, ZnO NPs/AA treated sectioned tooth enamel was exposed to S. mutans to evaluate its effects. The mechanical properties, including microhardness and surface morphology, were analyzed using Vickers microhardness testing and Atomic Force Microscopy (AFM). Additionally, the controlled release kinetics of Asiatic acid were analyzed under physiological (pH 7.4) and acidic (pH 5.0) conditions to elucidate its pH-responsive drug delivery potential. A precisely synthesized ZnO NPs/AA with a sheet-assembled flower-like structure was observed through SEM analysis, while its composition and functionalization were further confirmed by FTIR and UV-DRS. Thermal stability was validated through TGA and DSC analyses, establishing ZnO NPs/AA as a highly thermally stable material for biomedical applications. ZnO NPs/AA exhibited remarkable multi-functional properties, including potent antibacterial activity, leading to an 85.25 % reduction in S. mutans biofilm biomass and an 81 % inhibition of EPS production. pH modulation studies demonstrated effective neutralization of acidogenic activity, maintaining a near-neutral pH (7.01 at 48 h), significantly outperforming ZnO NPs and the untreated control. Enamel treated with ZnO NPs/AA following exposure to S.mutans showed a 72.6 % increase in microhardness and a 80.93 % reduction in surface roughness, highlighting its ability to combat S.mutans induced demineralization and acid formation, thereby preserving the enamel integrity. This study establishes ZnO NPs/AA as a promising biomaterial with potent antibacterial, anti-biofilm, and enamel-protective properties. These findings highlight ZnO NPs/AA as a promising and innovative approach for mitigating enamel demineralization and combating biofilm-associated dental challenges.

While the brain has been identified as a major site of small plastic accumulation, fundamental information about their impacts at the cellular level remains limited. In this study, we investigated the neuronal uptake and toxicity of nanoplastics using the human neurons (LUHMES). LUHMES cells internalized polystyrene (PS) nanoplastics with a preference for 50\u202fnm particles, mainly through clathrin-mediated endocytosis and macropinocytosis. However, PS uptake by LUHMES cells was lower than that by other neural cell types. PS nanoparticles were predominantly localized in lysosomes and minimally in mitochondria. On the other hand, PS nanoparticles had no obvious effects on acute cytotoxicity, neurite outgrowth, and oxidative stress. This study provides essential data on the neuronal responses to nanoplastics and highlights the need for further evaluation of their neurodevelopmental impact.",

However, their high production costs and technical challenges underscore the need for more cost-effective alternatives. Niosomes, with their lower production costs, improved stability, and biocompatibility, have emerged as promising alternatives to liposomes in drug delivery. This study introduces immunoniosomes (INs), a novel class of antibody-conjugated niosomes, through two conjugation strategies: (i) UV-NBS, a site-specific covalent conjugation method utilizing an indole ring structure for moderate binding to the variable regions of antibodies and Fab fragments, and (ii) EDC/NHS chemistry, which conjugates antibodies to carboxylated niosomes via primary amines on lysine sidechains. Bevacizumab, a monoclonal antibody targeting VEGF and approved for the treatment of various cancers including glioblastoma multiforme (GBM), was used as a model therapeutic. Both Bevacizumab and its Fab fragment were conjugated to niosomes and evaluated in U87 glioma cells (overexpressing VEGF) and human umbilical vein endothelial cells (HUVECs) (representing normal VEGF expression). Physicochemical characterization of the conjugated niosomes confirmed hydrodynamic sizes ranging from 100 to 200\u00a0nm, neutral surface charge, and dispersity indices below 0.5-properties critical for effective cellular penetration and drug delivery. Cellular toxicity assays, conducted at a 10\u00d7 dilution from commonly reported concentrations, highlighted the role of the autocrine loop in U87 glioblastoma cells. Importantly, specific Nio-Fab conjugate formulations, created through both site-specific and randomized conjugation strategies, exhibited enhanced cytotoxicity toward U87 cells while sparing healthy endothelial HUVEC cells. In summary, this research establishes novel conjugation strategies to produce stable, site-specific, and randomized antibody-niosomal conjugates with enhanced half-life and selective toxicity against GBM cells. By offering an alternative route for antibody delivery through niosomal nanocarriers, these findings open new avenues for the development of more effective GBM therapeutics, warranting further non-clinical and clinical investigations.",

However, integration of CNPs based nanocomposite into nanofluid application has received little attention which presents a clear research gap. As a result, this study used a bio-based functionalized sodium carboxymethyl nanocellulose (ACNPs) synthesis from oil palm empty fruit bunch (OPEFB) as a template, to synthesize hybrid nanocomposites with metal oxide (MONPs) at varying ACNP-to-MONP weight ratio. The present of COO- groups on the ACNPs act as template for coordinating metal precursors, promoting uniform MONP growth and strong interaction with ACNPs. Characterization techniques such as Fourier-transform infrared spectroscopy (FTIR), X-ray photoelectron spectroscopy (XPS), X-ray diffraction (XRD), and field emission scanning electron microscopy (FESEM) confirm the successful formation of MONPs on ACNPs by examine the morphology, distribution, chemical states, and bonding environments of the MONPs on the ACNPs. Besides this, thermogravimetric analysis (TGA) and zeta potential characterization are also conducted to assess the thermal and colloidal stability of the produced hybrid nanocomposites. Based on the result, hybrid nanocomposite with 1:1 weight ratio of ACNPs to MONPs was selected as an optimized weight ratio. In order to evaluate the performance and efficiency of the produced hybrid nanocomposite in nanofluid, thermal conductivity test was conducted using KD2Probe. The result indicating that the utilization of ACNPs as template for nanocomposite synthesis leads to a significant optimum enhancement in the thermal conductivity at temperature 45\u00a0\u00b0C, improving it by approximately 129, 100, 80 and 56\u00a0% after adding ACNPs/Al2O3, ACNPs/ZnO, ACNPs TiO2 and ACNPs/MgO based hybrid nanocomposite which making it a promising candidate for water based-heat transfer application.",

This study introduces an engineered cell membrane coating strategy to enhance nanoparticle functionality in targeting efficiency and susceptivity to immune clearance. We developed an engineered biomimetic nanodrug delivery system by modifying nanoparticles with Gas6-overexpressing neural stem cell membranes for improving microglia targeting, pro-phagocytic properties and immunomodulatory effects, constructing a composite system designated as Gas6-NV-NPs. The system employs poly(lactic-co-glycolic acid) (PLGA) as a carrier to coencapsulate Rapamycin (RAP) and nicotinamide riboside (NR) (referred to as NPs), while leveraging Gas6 protein to specifically bind microglial surface receptors, enabling precise targeting of AD pathological regions. Our findings demonstrated that Gas6-NV-NPs restored lysosomal acidification in microglia, enhanced microglial phagocytic clearance of amyloid-\u03b2 (A\u03b2), and reinstated the anti-inflammatory phenotype in BV2 microglial cells.

However, the underlying mechanism for the toxic effects of nanoplastics on the BBB remain poorly understood. In this study, we explored the toxic effects of polystyrene nanoplastic (PSNP) on brain microvascular endothelial cells (BMECs), one of the most critical components for maintaining BBB integrity. Our results revealed that PSNP specifically accumulate in the endolysosomal system following their internalization by BMECs. This accumulation disrupts lysosomal function and blocks endolysosomal pathways, ultimately triggering methuosis-a unique form of cell death characterized by extensive cytoplasmic vacuolization. Although the endosomal sorting complexes required for transport (ESCRT) system is naturally activated as a cellular defense mechanism, it is insufficient to repair PSNP-induced lysosomal membrane damage. By enhancing ESCRT activity, we effectively restored lysosomal function, thereby preventing cellular methuosis and preserving BBB integrity. Therefore, our findings provide crucial insights into the mechanisms underlying PSNP-induced BBB disruption by focusing on methuosis in endothelial cells. These insights hold important implications for environmental toxicology and public health in the context of global plastic pollution.",

Autophagy, a conserved degradative pathway essential for maintaining cellular homeostasis and adaptation to stress, has recently become a focal point of nanotoxicology research. This review synthesizes current evidence on the interactions between NPs and autophagic pathways across diverse biological systems. Findings indicate that NPs can trigger autophagy as an early cellular response; however, prolonged exposure may lead to autophagic dysfunction, contributing to impaired cell viability and disrupted signaling. Particular attention is given to the physiochemical properties of NPs such as size, surface charge, and polymer type, which influence cellular uptake and intracellular trafficking. We also highlight key mechanistic pathways, including oxidative stress and mTOR modulation. Notably, most available studies focus almost exclusively on polystyrene (PS)-based NPs, with limited data on other types of polymers, and several reports lack comprehensive assessment of autophagic flux or downstream effects. In conclusion, a better understanding of NP-autophagy crosstalk-particularly beyond PS-is crucial to evaluate the real toxic potential of NPs and guide future research in human health and nanotechnology.",

ADCs consist of mAbs conjugated to the cytotoxic payloads via a linker, thus enabling tumor-specific delivery and reducing systemic toxicity. ACNPs add to this targeted therapeutic window by using nanoparticles. This conjugation promotes controlled drug release, higher drug-to-antibody ratios (DAR), and reduced off-target effects. ADCs exhibit precision in cell killing but face limitations such as antigen heterogeneity and Fc-mediated sequestration, whereas ACNPs enhance payload capacity and tumor penetration through their tunable physicochemical properties. ACNPs also facilitate multivalent binding by functionalizing multiple antibody molecules on their surface, improving target cell recognition and binding strength. Recent advancements include 14 FDA-approved ADCs and ACNPs in Phase I/II trials. A critical analysis of synthesis methods reveals that site-specific conjugation techniques enhance batch consistency, while characterization technologies, such as SEC-HPLC, LC-MS/MS, and SPR, address challenges related to DAR quantification and aggregation. Linker chemistry innovations, such as PEGylated maleimides balancing hydrophilicity and stability, are highlighted alongside emerging payloads. Despite progress, both platforms face translational hurdles: ADCs contend with manufacturing complexity and resistance mechanisms, while ACNPs require standardized in vitro models to predict in vivo behavior.

It manifests with hallmark motor symptoms such as tremors, rigidity, and bradykinesia, as well as severe non-motor complications. Current therapies provide symptomatic relief but fail to halt or reverse neurodegeneration, emphasizing that a disease-modifying treatment option is sorely needed. Mutations in glucocerebrosidase 1 (GBA1) gene encoding GCase or mutation-free reduction of GCase activity disrupt lysosomal function and drive \u03b1-synuclein (\u03b1-syn) accumulation, thereby leading to neuronal and motor function loss. To this end, restoring GCase activity by GBA1 gene therapy would potentially benefit a broad PD population with or without the genetic risk by intervening with the natural trajectory of the disease. In this study, we implemented localized GBA1 gene therapy by intracranial convection-enhanced delivery of plasmid DNA comprising human GBA1 gene carried by engineered polymeric nanoparticles capable of mediating widespread neuronal transgene expression. In an \u03b1-syn preformed fibril (PFF)-induced mouse model of PD, our therapeutic strategy mediated robust human GBA1 transgene expression in the SN to significantly reduce \u03b1-syn aggregation/accumulation, preserve tyrosine hydroxylase-positive dopaminergic neurons, and mitigate neuroinflammation. Remarkably, motor deficits were markedly improved, as demonstrated by grip strength, pole, and open field tests. These findings underscore the transformative potential of our nanoparticle-based GBA1 gene therapy in addressing the limitations of current standard-of-care treatments. We expect that our therapeutic strategy, upon clinical development and translation, may contribute to shifting the therapeutic paradigm from the current symptomatic management toward disease modification to ultimately provide PD patients with a curative therapeutic option.",

Here, we describe a tightly-regulated programmed cell revival process after exposure of cells to cell death-inducing lysosomotropic agents, such as L-leucyl-L-leucine methyl ester (LLOMe). In the initial stage of cell recovery, we observe increased chromatin accessibility and upregulation of genes and pathways associated with embryonic development, regeneration, stemness, and inflammation. Subsequently, vital pathways governing metabolism, organelle biogenesis, membrane trafficking, transport, and cytoskeleton remodeling are activated, resulting in the complete renewal of cells. Consistent with the links of this transcriptional profile to tissue repair and regeneration, we found LLOMe to enhance the healing of skin wounds and corneal alkali burns in mice, promote hematopoietic progenitor/stem cell production in Drosophila melanogaster, induce tadpole tail regeneration in frogs, and mediate axon regeneration in Caenorhabditis elegans. Using both genetic and pharmacological approaches, we show NF-\u0138B signaling to be critical for both cell revival and regeneration.

The Ridaifen (RID) compound series comprises structural analogues of tamoxifen that exhibit more potent anticancer activity and have been implicated in modulating autophagy. Here, we investigated how the RID compounds interact with autophagy and explored the factors contributing to their enhanced cytotoxicity. We synthesized RID derivatives containing varying numbers of basic side chains and evaluated their intracellular behavior. We assessed cell viability using an MTT assay and determined lysosomal pH by flow cytometry. To visualize the subcellular distribution of the RID derivative, we employed a fluorescent dye\u2012conjugated form of the compound. Additionally, we monitored autophagic and apoptotic markers through immunoblotting. RID-B demonstrated potent lysosomal neutralization and inhibited autophagic flux near its half-maximal inhibitory concentration. This neutralization led to the accumulation of insoluble SQSTM1-containing aggregates, implicating proteotoxic stress in apoptosis. Confocal imaging revealed proton-dependent lysosomal localization of RID-B, followed by partial cytoplasmic translocation. Notably, co-treatment with bafilomycin A1 reduced RID-B\u2012induced apoptosis, underscoring lysosomal dysfunction initiated apoptotic signaling. Analyses across multiple RID derivatives showed a correlation among the number of basic side chains, lysosomal neutralization, and between lysosomal neutralization and cytotoxicity. Our findings indicate that basic side chains markedly enhance lysosomotropic behavior, enabling sustained autophagy inhibition and apoptosis induction. By revealing a strong link between lysosomal neutralization and proteotoxic cell death, the results suggest that modified tamoxifen analogues, such as RID-B, may offer a promising strategy to overcome autophagy-related drug resistance in cancer therapy.",

These nanocapsules coencapsulate GOx and HRP while acting as size-exclusion membranes, allowing selective diffusion of small molecules while retaining the enzymes. Confocal studies with BODIPY-labeled GOx and Cy5-labeled HRP ensure the encapsulation of both enzymes within the HPOCs and are found to be localized in the lysosome. The HPOCs exhibit excellent biocompatibility and, under hypoxic conditions, trigger substantial cancer cell apoptosis (\u223c75% cell death) and G2/M cell cycle arrest.

This study delineates the differential effects of two widely used nanocarriers-mesoporous silica (MSNs) and albumin (ANPs) nanoparticles-on lysosomal biology, with a focus on the expression and activity of cathepsins (CtsB and CtsD), which are key proteases involved in protein degradation and maintaining cellular balance. These two types of nanoparticles, differing in their material and degradability, exhibit distinct behaviors inside the cell. We demonstrate that inorganic MSNs cause significant changes in lysosomal function by altering lysosomal content and cathepsin levels, without triggering lysosomal membrane permeabilization-a typical response to organic particle stress. In contrast, ANPs-which are susceptible to lysosomal cathepsin degradation-induce milder changes in cathepsin expression and maintain lysosomal integrity.

AC-loaded nanoparticles (AC-NPs) with a particle size less than 100 nm improved drug solubility and facilitated intracellular accumulation. Assessment of cytotoxicity revealed that AC-NPs significantly and more effectively suppressed the growth of breast cancer cells than free AC extracts. After 72 h, IC50 values for MDA-MB-231 (triple-negative) and MCF-7 (estrogen receptor-positive) were 46.9 and 75.6 \u03bcg/mL, respectively, with greater sensitivity observed in MDA-MB-231 cells. AC-NPs exhibited minimal toxicity toward normal mammary epithelial cells (NMuMG), indicating good biocompatibility. Fluorescently labeled AC-NPs showed rapid, time-dependent uptake in both cancer cell lines. Particularly, MDA-MB-231 cells exhibited rapid internalization, whereas MCF-7 cells likely benefited from hyaluronic acid-mediated targeting of CD44 receptors. In conclusion, AC-NPs enhanced the solubility, cellular uptake, and anticancer efficacy of AC while maintaining biocompatibility, thereby suggesting their robust potential as nanocarrier platforms for breast cancer therapy.",

In this study, we aimed to investigate if MONPs of varying solubility are similarly sequestered intracellularly, including in lysosomes and the role of the acidic lysosomal milieu on toxicity induced by copper oxide (CuO) nanoparticles (NPs), nickel oxide (NiO) NPs, aluminum oxide (Al2O3) NPs, and titanium dioxide (TiO2) NPs of varying solubility in FE1 lung epithelial cells. Mitsui-7 multi-walled carbon nanotubes (MWCNTs) served as contrasts against particles. Enhanced darkfield hyperspectral imaging (EDF-HSI) with fluorescence microscopy was used to determine their potential association with lysosomes. The v-ATPase inhibitor Bafilomycin A1 (BaFA1) was used to assess the role of lysosomal acidification on toxicity. The results showed co-localization of all MONPs with lysosomes, with insoluble TiO2 NPs showing the greatest co-localization. However, only acute toxicity induced by soluble CuO NPs was affected by the presence of BaFA1, showing a 14% improvement in relative survival. In addition, all MONPs were found to be associated with large actin aggregates; however, treatment with insoluble TiO2 NPs, but not soluble CuO NPs, impaired the organization of F-actin and \u03b1-tubulin. These results indicate that MONPs are sequestered similarly intracellularly; however, the nature or magnitude of their toxicity is not similarly impacted by it. Future studies involving a broader variety of NPs are needed to fully understand the role of differential sequestration of NPs on cellular toxicity.",

A clinical \"paradox breaker\" inhibitor of BRAF monomers and dimers can potentially evade drug resistance. However, patients are required to receive a high oral daily drug dose to achieve the target therapeutic window. Co-administration of a cytochrome P450 blocker can improve drug exposure, but the combination can lead to drug-drug interactions. We investigated delivery via fucoidan-based nanocarriers to improve pharmacologic properties. We found that the nanoparticles extended BRAF inhibition in cancer cells due to sequestration into endolysosomes, followed by controlled release from a lysosomal depot. Following intraperitoneal administration, nanoparticles improved drug pharmacokinetics in vivo without inhibiting cytochrome P450 and also resulted in substantial improvements in antitumor efficacy. This work describes a general nanotherapeutic strategy to improve the pharmacologic properties of drugs via intracellular depot formation.",

However, the intracellular efficiency of BGNs is limited by the internalization mechanism, further dictating the intracellular trafficking and fate. Following a general overview of the main uptake pathways of nanoparticles and the subsequent intracellular localization, a comprehensive analysis of the BGNs' internalization process is presented. Key findings reveal that the BGNs are mainly internalized by active transport mechanisms and are entrapped in endosomes/lysosomes, limiting their ability to exert their full intracellular therapeutic potential. Existing studies in the literature provide valuable data to correlate the uptake process with the intracellular BGN localization, but there is limited research on the fate of BGNs and the released ions once entrapped in intracellular vesicles. Therefore, in the last part, future strategies to either escape the endosome or use the lysosomal degradation as a mechanism for controlled intracellular ion release with implications for targeted modulation of cell behavior are discussed. Going beyond BGNs, this review highlights the need of understanding better the dynamically transforming degradable nanoparticles - an essential step toward achieving their full intracellular therapeutic potential.",

Yet, the influence of specific ligands present on the cargo, like lipopolysaccharide (LPS), on phagosome maturation is unclear. Using sterile, non-immunogenic particles as model cargo phagocytosed by macrophages, this study showed\u00a0that in the absence of a specific ligand on the cargo, less than half the cargo-loaded phagosomes fuse with lysosomes. Quantification of phagosome maturation revealed that early events triggered by LPS-induced signaling enhance both cargo delivery to lysosomes and phagosome acidification rates. Specifically, it is demonstrated that stress-activated p38 alpha mitogen-activated protein kinase (p38 MAPK) enhances phagosome maturation under LPS-triggered signaling. Other signals known to activate p38 MAPK such as flagellin, IgG, and albumin, also enhance lysosomal delivery of phagocytosed cargo. The work indicates that phagosome maturation in macrophages is enhanced by specific ligands on the cargo, which activate cell surface receptors that signal via p38 MAPK.",
"40972746": "ID: 40972746\nTitle: Hybrid cell-membrane-coated biomimetic nanoparticles for targeted noninvasive intervention in early diabetic retinopathy.\nAbstract: Diabetic retinopathy (DR), a diabetes mellitus-induced ocular complication, demands non-invasive and effective early interventions to halt disease progression. Here, we developed biomimetic hybrid nanoparticles ([RBC-EC]-NPs) by coating fused membranes derived from red blood cells (RBC) and retinal endothelial cells (EC) on poly (lactic-co-glycolic acid) (PLGA) cores. Optimizing the membrane-to-PLGA ratio to 1:2 yielded stable nanoparticles that preserved critical membrane proteins, including CD47 (for immune evasion) and vascular endothelial cadherin (for endothelial targeting). The dual-coating strategy synergistically enhanced retinal endothelial targeting, suppressed pathological EC migration, and prolonged systemic circulation. In a STZ-induced diabetic rat model, intravenously administered [RBC-EC]-NPs selectively accumulated in retinal vasculature, significantly downregulating vascular endothelial growth factor expression, mitigating vascular leakage, thereby reducing formation of acellular capillary. Transcriptomic analysis revealed nanoparticle-mediated restoration of lysosomal function, lipid metabolism, and tumor necrosis factor-associated inflammatory pathways. Notably, systemic treatment also ameliorated dyslipidemia without inducing hematological or hepatic toxicity. Comprehensive biosafety evaluations confirmed the absence of acute tissue damage. Together, these findings demonstrated that [RBC-EC]-NPs could represent a potent and targeted nanotherapeutic platform for early-stage DR intervention, combining dual-cell membrane advantages with high biocompatibility. STATEMENT OF SIGNIFICANCE: Diabetic retinopathy (DR) remains a leading cause of blindness, and current treatments are largely invasive and limited to late stages. Here, we developed hybrid red blood cell-endothelial cell membrane-coated nanoparticles ([RBC-EC]-NPs) as a minimally invasive intravenous therapy. These biomimetic NPs uniquely combine endothelial targeting and immune evasion, enabling selective retinal vascular accumulation. Mechanistically, [RBC-EC]-NPs reduced VEGF overexpression, restored lysosomal-autophagy function, suppressed inflammation, and rebalanced lipid metabolism, thereby alleviating vascular leakage, preserving retinal microcirculation, and improving systemic lipid profiles in diabetic rat models. This study demonstrates the potential of [RBC-EC]-NPs as a safe, multifunctional therapeutic platform that targets the metabolic and vascular pathogenesis of early DR, offering a promising alternative to current intravitreal interventions.",

Amy possesses multiple beneficial pharmacological activities, such as anticancer properties, blood sugar reduction, and immune enhancement. Based on previous research about the biological properties of Amy in different ion strength solutions, it was found to have certain self-assembly potential. In this study, a Ca2+ assisted self-assembly nanoparticle based on Amy is fabricated. The ability of metal ions to form Amy nanoparticles is explored with respect to the Amy concentrations, proportion of constituents, and temperature conditions. Dynamic light scattering (DLS) was employed for detection, revealing that the diameter of Amy-Ca2+ nanoparticles (ACNPs) ranges from 122 to 459\u00a0nm, with a polydispersity index (PDI) of 0.377. Subsequently, the assembly mechanism of ACNPs is investigated using ultraviolet-visible (UV-vis) spectra, Fourier transform infrared (FT-IR) spectra, and H nuclear magnetic resonance (H NMR) spectra. It is demonstrated that there is a hydrogen bonding interaction between Amy and Ca2+, and it is likely that the non-hydroxyl hydrogen at the position of the Amy sugar group interacts with Ca2+. Furthermore, the potential of ACNPs in an antivirus assay was validated by using respiratory syncytial virus (RSV) as an infection model. The results reveal that Amy exhibits anti-RSV activity to some degree, and when combined with calcium sulfate (CaSO4), another common food additive, it significantly enhances the anti-RSV effect. The enhanced anti-RSV effect may be attributed to the self-assembly phenomenon of Amy and Ca2+. In addition, in vitro hemolysis assays and cytotoxicity tests have demonstrated that ACNPs are biocompatible and safe. All in all, this study reveals the potential application of natural ingredient Amy in antivirus bioaction, highlighting its dual roles as a bioactive ingredient.",
"41026805": "ID: 41026805\nTitle: Expansion of lysosomal capacity in early adult neurons driven by TFEB/HLH-30 protects dendrite maintenance during aging in Caenorhabditis elegans.\nAbstract: Lysosomes are essential for neuronal homeostasis, providing degradation and recycling functions necessary to support neurons' complex operations and long lifespans. However, the regulation of lysosomal degradative capacity in healthy neurons is poorly understood. Here, we investigate the role of HLH-30, the sole Caenorhabditis elegans homolog of Transcription Factor EB (TFEB), a master regulator of lysosome biogenesis and autophagy that is thought to predominantly function in the context of starvation or stress. We demonstrate that HLH-30 is dispensable for neuronal development but acts cell-intrinsically to expand lysosomal degradative capacity during early adulthood. Loss of HLH-30 leads to lysosomal dysfunction and delayed turnover of synaptic vesicle proteins from the synapse. Notably, we show that basal HLH-30 activity is sufficient to expand neuronal lysosomal capacity without nuclear enrichment, in contrast to the nuclear translocation associated with starvation- and stress-induced activation of TFEB and HLH-30. Furthermore, we show that neuronal lysosomal function declines with age in wild-type animals, and this corresponds to a decrease in basal HLH-30-mediated transcription. We further demonstrate that basal HLH-30 activity is crucial for neuron maintenance: lysosomal dysfunction due to inadequate HLH-30 activity leads to dendrite degeneration and aberrant outgrowths. In summary, our study establishes a critical role for HLH-30/TFEB in promoting lysosomal capacity to preserve neuronal homeostasis and structural integrity of mature neurons in vivo.",

However, research on the intracellular complete migration of NPs is limited, particularly with respect to exocytosis. Here, we exposed human macrophages to polystyrene nanoplastics (PS-NPs) and observed that PS-NPs induced the accumulation of lysosomes within the cells and lead to an increase in their contents. Additionally, PS-NPs co-localized with lysosomes and triggered lysosomal activation. Using a previously established method for PS-NPs adsorption to intracellular proteins and employing proteomic and bioinformatic approaches, we confirmed that after entering the cell, PS-NPs predominantly adsorbed proteins related to the lysosomal pathway, and stably adsorbed the key lysosomal protein cathepsin D (CTSD). Further studies identified that PS-NPs induced lysosomal exocytosis, during which the lysosomal-specific mature-CTSD adsorbed onto PS-NPs and was co-released from the cell. This process was mediated by Ca2+. In summary, this study elucidated the lysosome-dependent transcytosis of PS-NPs and established a novel method for verifying lysosomal exocytosis using mature-CTSD as a marker.",

This study investigated 3 structurally distinct Ni-X-NP-pure NiO (NCZ), NiO@Ni(OH)2 (SIG), and Ni@NiO@Ni(OH)2 (AA)-to determine how core composition and surface functionalization contribute to bioactivity. Each Ni-X NP was modified with surface moieties (-OH, -COOH, and -CH3) to assess the efficacy of surface modifications in reducing bioactivity. Ni-X NP were thoroughly characterized for structure, surface chemistry, and Ni2+ ion release in simulated lysosomal fluid. Red blood cells (RBCs) were used to evaluate the hemolytic capabilities of the nanoparticles, and primary murine alveolar macrophages (AM), and murine ex vivo alveolar macrophages (mexAM) were used to assess uptake, cytotoxicity, IL-1\u03b2 release, and lysosomal membrane permeability (LMP). Results showed that NiO@Ni(OH)2 nanoparticles induced the greatest hemolysis in RBC, elicited the greatest IL-1\u03b2 response in AM and mexAM, and produced the most LMP in mexAM. The Ni@NiO@Ni(OH)2 nanoparticle released the most Ni2+ and caused profound reductions in AM cell viability but failed to cause RBC hemolysis or LMP. Pure NiO nanoparticles exhibited minimal bioactivity and low Ni2+ release. Surface modification with (-COOH) or (-CH3) effectively reduced bioactivity in LMP-mediated inflammation but had minimal effect on Ni2+-driven toxicity. This study reveals that Ni-X NP bioactivity depends on both core composition and surface chemistry, and that surface functionalization reduces inflammation only when lysosomal damage is the primary driver. These findings underscore the need for careful design and evaluation of engineered nanomaterials.",

Herein, we successfully develop a synthetic strategy involving the construction of pH-activated probe backbones by the atom transfer radical polymerization technique with methacrylates with different substituents as monomers. Subsequently, a fluorescence probe is prepared by integrating hydrophobic aggregation-induced luminescence (AIE) fluorescence dyes and aggregation-induced bursting (ACQ) dyes into ACQ/AIE ratio imaging nanoparticles through covalent bonding and self-assembly techniques. Such AIE probe can monitor lysosomal acidification defects in AD and elucidate their role in A\u03b2 phase separation. Interestingly, our new findings reveal that A\u03b2 accumulation synergizes with lysosomal dysfunction (the pH value itself has not changed) to induce pathological LLPS, thereby providing a novel approach for phase modulation and attenuating AD progression. Taken together, our design concept provides a novel strategy to regulate phase separation, potentially reducing or delaying A\u03b2 aggregation and AD progression.",

Here, we quantitatively tracked and demonstrated that such heterogeneity dynamically reshaped bivalve hemocyte burden in non-additive modes with subpopulation-specific consequences for immune function. Kinetic modeling revealed distinct internalization patterns and selectivity among hemocyte subpopulations, driven by particle proportions and uptake dynamics. Granulocytes displayed indiscriminate capacity for MNP internalization, maintaining high uptake efficiency across varying particle compositions. In contrast, semigranulocytes showed selective internalization behavior sensitive to particle size distributions, facilitating preferential uptake shifts as nanoparticle proportions varied. Mechanistically, large NPs accelerated the internalization of smaller NPs via a hitchhiking effect but simultaneously competed for intracellular processing pathways, limiting maximal uptake. Notably, co-exposure with smaller NPs significantly enhanced and accelerated MPs internalization, leading to intracellular overload with severe lysosomal damage and mitochondrial impairment. These disruptions potentially triggered mitochondria-lysosome crosstalk and autophagy, particularly pronounced in semigranulocytes. Ultimately, the combined presence of multiple particle sizes resulted in cascading impairment of hemocyte phagocytic capacity than exposure to individual particles alone, highlighting particle-size interactions as critical determinants of immunotoxicity. Our findings underscored how coordinated disposal of hemocyte subpopulations influenced the mixed-size plastic clearance, providing new insight on the health risks posed by MNPs to marine organisms.",

We employed an in vitro cellular bioassay to investigate the distribution, metabolic disruption, and genotoxicity resulting from 24\u202fh of exposure to polystyrene nanoplastics (NanoPS, approximately 90\u202fnm) in the hemocytes of the Pacific oyster (Crassostrea gigas). Transmission electron microscopy suggested the internalization and distribution of NanoPS within vesicles, the cytosol, and the nuclei of exposed hemocytes. Cytotoxicity assays revealed that metabolic activity (resazurin assay, LC50\u202f= 91.6\u202fmg/L) was more sensitive than lysosomal integrity (neutral red assay, LC50\u202f= 252.3\u202fmg/L). Exposure to NanoPS also increased the levels of reactive oxygen species and DNA damage as low as 1.2\u202fmg/L. Metabolic assays revealed that enhancing mitochondrial metabolism through galactose supplementation increased the cytotoxicity and DNA damage caused by NanoPS. Conversely, promoting anaerobic metabolism with glucose supplementation reduced these effects. Co-exposures with the mitochondrial uncoupler FCCP did not decrease cellular viability but elevated DNA damage. We suggest that mitochondria are a sensitive target of nanoplastics in bivalve hemocytes, highlighting the importance of considering aerobic metabolism in assessing nanoplastic toxicity. The strong correlation with the published in vivo effects of this same NanoPS highlights the biological relevance of this cellular toxicity assessment. This research supports the use of hemocyte-based cellular assays to complement in vivo studies for characterizing nanoplastic toxicity mechanisms in marine organisms.",

LRRK2 mutations increase the phosphorylation of Rab substrates including Rab12 and Rab10. Rab12 and Rab10 are expressed in neuronal and non-neuronal cells with localization to membranes in the endolysosomal compartment, and lysosomal stress activates LRRK2 phosphorylation of Rabs. In this study, using antibodies directed to the LRRK2-mediated phosphorylation sites on Rab12 at amino acid Ser106 (pS106-Rab12) and Rab10 at amino acid Thr73 (pT73-Rab10), we test whether aberrant LRRK2 phosphorylation is associated with tau and/or \u03b1-synuclein pathology across clinically distinct neurodegenerative diseases. Analysis of brain tissue lysates and immunohistochemistry of pathology-susceptible brain regions demonstrate that pS106-Rab12 levels are increased in Alzheimer's disease (AD) and Lewy body disease (LBD), including PD with and without G2019S LRRK2 mutation. At early pathological stages, phosphorylated Rab12 localizes to granulovacuolar degeneration bodies (GVBs), which are thought to be active lysosomal-like structures, in neurons. pS106-Rab12-positive GVBs accumulate with pathological tau across brain tissues in AD and LBD, and in G2019S LRRK2 mutation carriers. In a mouse model of tauopathy, pS106-Rab12 localizes to GVBs during early tau deposition in an age-dependent manner. While GVBs are largely absent in neurons with mature protein pathology, subsets of both tau and \u03b1-synuclein inclusions appear to incorporate pS106-Rab12 at later pathological stages. Further, pS106-Rab12 labels GVBs in neurons and shows co-pathology with tau inclusions in primary tauopathies including Pick's disease, progressive supranuclear palsy, and corticobasal degeneration. Finally, pT73-Rab10 is elevated and localizes to GVBs, but not tau and \u03b1-synuclein inclusions, in AD and LBD, including G2019S LRRK2 mutation carriers. These results implicate LRRK2 kinase activity and Rab phosphorylation in endolysosomal dysfunction in tau- and \u03b1-synuclein-associated neurodegenerative diseases.",

Tetracyclines, particularly doxycycline, have demonstrated multimodal neuroprotective effects, both in vitro and in vivo. The non-antibiotic derivative of doxycycline 4-dedimethylamino-12a-deoxydoxycycline (DDOX), has been recently shown to rescue neurons from oxidative injury. Here, we demonstrate that DDOX showcases a diverse range of mechanisms targeting \u03b1-Syn aggregates. Notably, DDOX inhibited the aggregation of \u03b1-Syn and the seeding ability of \u03b1-Syn pre-formed fibrils (PFF) in biophysical and cellular assays. In addition, the compound ameliorated the relocalization of total and phospho-\u03b1-Syn, triggered by exogenous \u03b1-Syn PFF. Surprisingly, DDOX drastically mitigated lysosomal stress induced by these aggregates. Moreover, we determined that DDOX effectively impeded the internalization of fluorescently labeled \u03b1-Syn PFF. Biophysical techniques and molecular docking simulations suggest that DDOX binds to hydrophobic patches on \u03b1-Syn fibrils. Our findings reveal novel neuroprotective attributes of tetracyclines, wherein a direct extracellular interaction between DDOX and \u03b1-Syn aggregated species mitigates their intracellular impact. These results provide a promising foundation for DDOX, a drug that aims to interfere with the intracellular seeding, propagation and uptake of \u03b1-Syn fibrils in neurodegenerative conditions.",

Blood-brain barrier (BBB) penetration was evaluated using in vitro transwell models and in vivo mouse models. Lysosomal function, autophagy, pathological protein clearance, and anti-inflammatory effects were assessed using various cellular and molecular biology techniques. MSC-PLGA-NPs demonstrated 2.3-fold higher BBB penetration efficiency compared to PLGA alone. In a chloroquine(CQ)-induced lysosomal injury model and mice model, they effectively restored lysosomal pH, enhanced autophagy (reducing LC3-II/I ratio by 0.4-fold and p62 expression by 52%), cleared amyloid precursor protein (APP) and phosphorylated tau (p-tau) proteins, and inhibited IL-6 and TNF-\u03b1 without hepatorenal toxicity.

Among the various solutions for the desalination process, the solar still is the most prominent due to its cost-effectiveness and sustainable approach. The current experimental study proposes a new technique aimed at improving the functioning of hemispherical solar stills (HSS) by applying the carbonized nanoparticles (ACNPs) made from spent tea dust on the absorber plate. This method enhances the thermal conductivity and absorptivity of the surface. Incorporating ACNPs into the black paint results in increased thermal energy absorption, which raises the temperature of the absorber and water, thus increasing the yield of freshwater. To our knowledge, this is one of the first studies to incorporate waste-derived activated carbon nanoparticle coatings, examining their effects on the thermal and operational efficiency of HSS in realistic outdoor environments. This offers an inexpensive and easily adaptable upgrade to solar desalination systems. The research involved the fabrication of two identical solar stills: one featuring a conventional black surface coating, termed HSS, and the other incorporating activated carbon nanoparticles dispersed in black paint and applied on the absorber. The experimental results revealed that the thermal performance has significantly improved. The modified HSS recorded a peak absorber and water temperature of 74 and 72[Formula: see text]C, whereas the peak temperatures recorded from the conventional HSS were 71 and 69[Formula: see text]C, yielding average gains of 4.34% and 4.16% on absorber and water temperature, respectively. The improved heat transfer through evaporation leads to a higher temperature difference between the water and cover (20[Formula: see text]C (modified HSS) and 18 [Formula: see text]C (conventional HSS)), which results in an efficient condensation process. Moreover, there has been a substantial improvement in freshwater collection. The modified HSS produced a maximum hourly yield of 1.07 kg/[Formula: see text] and a cumulative daily yield of 5.06 kg/[Formula: see text], which is 33.67% higher than the conventional HSS yield of 3.72 kg/[Formula: see text]. This performance boost led to a substantial increase in efficiency. The daily thermal efficiency increased from 32.79% to 49.44%, and the daily exergy efficiency improved from 3.12% to 5.82%. An economic analysis demonstrated the viability of the modified system, with a payback period of 1.98 years and notable long-term savings. The use of spent tea dust for ACNP synthesis highlights the environmental and cost benefits of this approach. The findings highlight the potential of nano-enhanced coatings to enhance solar desalination technologies, offering an effective and sustainable solution for addressing global water challenges.",
"41331534": "ID: 41331534\nTitle: E3 ligase AREL1 controls perinuclear localization of lysosomes and supports Purkinje cell survival.\nAbstract: Localization of lysosomes influences their properties, e.g., perinuclear lysosomes are more acidic but less mobile compared with the peripheral ones. Furthermore, the endoplasmic reticulum (ER) can actively regulate the dynamics and functions of lysosomes via membrane contact sites. In this study, we find that ER-resident apoptosis-resistant E3 ubiquitin protein ligase 1 (AREL1) establishes membrane contacts with lysosomes by directly interacting with the Voa subunit of V-ATPase. AREL1 also catalyzes K33-linked polyubiquitylation of V-ATPase V1B2 subunit, inducing its binding to UBAC2 localized in the perinuclear ER. Depletion of AREL1 or UBAC2 increases the number of peripheral lysosomes that possess partially assembled V-ATPase, elevated luminal pH, and attenuated degradative capacity. Knockdown of ZRANB1, the deubiquitylating enzyme that antagonizes AREL1-mediated V1B2 ubiquitylation, promotes perinuclear clustering of lysosomes and increases lysosomal acidity and degradation. Mice lacking Arel1 exhibit age-dependent Purkinje cell loss, an ataxic phenotype, and motor impairment. Lipofuscin accumulation in the residual Purkinje cells of Arel1-/- mice indicates lysosomal dysfunction. Orchestration of lysosomal positioning and function by the AREL1-UBAC2-V-ATPase axis underscores the physiological significance of ER-regulated perinuclear lysosomal positioning in neurons.",

However, their influence on the toxicokinetics and biological effects of NPs in marine mussels remains largely unknown. Here, the green mussels (Perna viridis) were exposed to NPs and HAs at their environmentally relevant concentrations for 21 d, followed by a 7-d depuration phase. The effects on toxicokinetics, immunological responses, and microbiota of digestive gland were evaluated. The results showed that HAs increased the uptake rate constant in digestive gland by 5.5-fold and tissue accumulation of NPs by 2.5-fold compared to NPs alone, resulting in higher NPs burdens after depuration. Meanwhile, HAs exacerbated NPs-induced immunotoxicity, including increased hemocyte mortality and ROS production, and decreased phagocytosis and lysosomal membrane stability. Moreover, HAs led to more pronounced dysbiosis of microbiota in digestive gland than NPs alone, reducing fungal diversity by 56\u202f% and enriching opportunistic fungal pathogens such as Fusarium, while bacterial communities showed minor shifts. This study has provided critical evidence that HAs act as a \"Trojan horse,\" exacerbating NPs risks.

This system undergoes smart multistage transformations to overcome key delivery barriers: It first circulates as large, negatively charged nanoparticles to prolong plasma half-life; then converts to small, positively charged particles via tumor-overexpressed heparanase for deep tumor penetration; and finally assembles into long nanofibers triggered by lysosomal cathepsin B and acidity to extend tumor retention. Importantly, the nanofibers mechanically disrupt lysosomes, increasing lysosomal membrane permeability, inhibiting AKT activation, reducing autophagy, and impairing cytoskeletal integrity\u2500synergistically sensitizing tumors to radiation. This strategy combined with 6 Gy radiation achieved 82.5% tumor suppression in conventional U251 models and 60.4% in radioresistant U87 models, significantly outperforming the clinical radiosensitizer sodium glycididazole. This strategy provides a paradigm for overcoming GBM radioresistance by leveraging bioresponsive nanoscale transformations and lysosomal targeting.",

Encapsulation of Pc in ANP) significantly enhances its biological effects in photodynamic therapy by increasing cellular uptake through receptor-mediated endocytosis and promoting lysosomal accumulation. This leads to marked lysosomal stress and regulated necrotic cell death pathway, while free Pc causes moderate oxidative stress with reversible apoptosis and autophagy. The enhanced phototoxicity of encapsulated Pc was evident across multiple cancer cell lines, especially aggressive phenotypes, whereas resistant lines showed lower sensitivity likely due to efficient ROS scavenging. Despite improved initial uptake, rapid lysosomal release and extracellular extrusion of Pc limit long-term intracellular retention. Morphological and gene expression analyses confirmed distinct cell death mechanisms between free and encapsulated Pc, underscoring the critical role of nanocarrier-mediated delivery in modulating oxidative stress and cellular response. These findings highlight the importance of nanoparticle design in optimizing PDT efficacy by effectively triggering necrotic cell death pathway.",

Polystyrene nanoplastics (PS-NPs) are among the most extensively studied because of their wide occurrence, physicochemical stability, and availability for laboratory research. Their nanoscale size enables interaction with biological systems at the molecular level, promoting internalization, intracellular trafficking, and potential bioaccumulation. This review summarizes current knowledge on the cellular effects and molecular mechanisms of PS-NPs, particularly in human gastrointestinal models. The gastrointestinal tract is a primary route of nanoplastic exposure, where PS-NPs can cross epithelial barriers, interact with immune and epithelial cells, and disturb cellular homeostasis. Once internalized, PS-NPs can induce oxidative stress, mitochondrial dysfunction, and dysregulation of autophagy, leading to alterations in lipid and glucose metabolism. Excessive synthesis of reactive oxygen species may trigger DNA damage, activate the ATM/ATR-p53 signaling pathway, and impair DNA repair mechanisms, thereby contributing to genomic instability. Emerging evidence also shows that PS-NPs can interact with ion channels, affecting calcium homeostasis, membrane potential, and cell viability. Overall, these findings highlight the complex and multifaceted toxicity of PS-NPs at the cellular level and underscore the need for further research to assess the long-term risks of nanoplastic exposure.",

Vibrio ostreicida was firstly identified as a lethal pathogen for oyster larvae (Ostrea edulis), but its interactions with the immune system of the bivalve host are largely unexplored. In this study, we investigated the pathogenic potential of a V. ostreicida strain r172, isolated from a 2022 mortality event in adult Mytilus galloprovincialis in the Ebro Delta (Spain), focusing on mussel early larval development and hemolymph immune responses in in vitro short-term exposure experiments. Immune responses were compared with those of the oyster Magallana gigas. Both live and heat-killed V. ostreicida significantly impaired normal larval development with a dose-concentration effect (EC50 \u2248 103 - 104 CFU/mL), with live bacteria inducing shell malformations and heat-killed Vibrio causing developmental arrest. In the hemocytes of adult mussels, exposure to heat-killed V. ostreicida led to dose-dependent lysosomal destabilization, reduced phagocytic activity, and increased intracellular ROS production. Similar lysosomal destabilization was observed with live V. ostreicida, which also stimulated extracellular ROS and nitric oxide release, but only in the presence of hemolymph serum (HS). Mussel HS displayed a strong bactericidal activity towards V. ostreicida, highlighting a key role for soluble immune effectors. In oyster hemocytes, V. ostreicida induced similar lysosomal stress; however, neither hemocytes nor serum showed any bactericidal activity towards this strain. This data represents the first attempt to elucidate the mechanisms underlying the interactions of an environmental strain of V. ostreicida with marine bivalves. The species-specific differences observed in immune responses highlight the complexity of host-pathogen interactions in these organisms and emphasize the need for further investigation into immune responses of different aquacultured species.",

Dysfunction in beta-glucocerebrosidase (GCase) and leucine-rich repeat kinase 2 (LRRK2) mutation are genetic risks for developing synucleinopathies. However, whether pharmacological GCase activation ameliorated synucleinopathies in LRRK2-PD was unexplored. Here, we showed that long-term treatment of ambroxol (ABX), a brain-penetrant GCase activator, reduced \u03b1-syn oligomer accumulation in aged mutant LRRK2R1441G mouse striatum. Acute ABX treatment (50\u2009\u00b5M) increased cellular GCase enzymatic activity and reduced Ser129-\u03b1-syn phosphorylation in human SH-SY5Y cells and mutant LRRK2 mouse fibroblasts, independent to LRRK2 kinase activity. Real-time DQ-BSA assay revealed lysosomal dysfunction in mutant MEFs, which was partially attenuated by ABX treatment. Lysosomal stress by bafilomycin-A1 induced endogenous GCase activity in wildtype (WT) MEFs, which was not observed in the LRRK2 mutant. Single gavage of ABX (400\u2009mg/kg) in aged mice achieved peak drug level in serum and brain within 6\u2009h post-administration. Ad libitum feeding of ABX (in food pellets) over 18 weeks (average dose: 45.9\u2009mg/kg/day) elevated brain GCase activity in both WT and mutant striatum without affecting body weight. This regimen significantly reduced \u03b1-syn oligomer level in mutant striatum to a comparable physiological level in age-matched WT without altering total \u03b1-syn and Ser129-phosphorylation levels. This is the first study demonstrating reduced \u03b1-syn oligomer accumulation by chronic treatment of GCase activator in aged mouse brains vulnerable to PD, suggesting early intervention to alter progression of synucleinopathies as a key determinant of clinical outcomes of PD.",

Utilizing a homozygous RNASEK knockout mouse, we demonstrate that the null function of RNASEK leads to catastrophic developmental failure at the egg cylinder stage (E5.5). Rnasek-/- embryos exhibit pronounced lysosomal dysfunction and multilineage proliferation arrest, accompanied by the hallmarks of senescence, including elevated p21, reduced Ki67 and EdU incorporation as well as increased \u03b3H2AX foci, which are evident in\u00a0vitro embryo culture as well. Unexpectedly, despite increased V0/V1 subunit colocalization, lysosomal alkalization, proteolytic failure, and autophagic flux blockade collectively indicate that the loss of RNASEK promotes malfunctional V-ATPase assembly. Pharmacological restoration of lysosomal acidity via EN6 partially mitigates senescence and extends the developmental window. These findings demonstrate that RNASEK regulates lysosomal function via V-ATPase and is required for egg cylinder development in the mouse embryo. Loss of RNASEK promotes premature senescence of multiple cell lineages, terminating early embryonic development.",

The risk allele increases GPNMB transcription and GPNMB protein levels in the CSF highlighting GPMNB as a potential biomarker for Parkinson's disease. However, a lack of knowledge of GPNMB's function and mechanism of secretion has hindered an interpretation of secreted GPNMB levels. In this study, we assessed the mechanism of GPNMB secretion by macrophages, the primary cell type expressing GPNMB in the brain. We show that GPNMB is secreted in response to lysosomal stress via lysosomal exocytosis and highlight the Parkinson's disease risk factor LRRK2 as a strong modulator of GPNMB secretion.",
"41416489": "ID: 41416489\nTitle: Reshape Intracellular/Extracellular pH for Enhanced Nanocatalytic Ferroptosis and cGAS-STING Activation Induced Immunotherapy.\nAbstract: Nanometal-based therapies face challenges arising from the overexpression of proton efflux transporters in cancer cells, which acidifies the extracellular tumor microenvironment (TME) while preserving a relatively neutral intracellular pH, thereby compromising therapeutic efficacy and fostering an immunosuppressive TME. Here, we integrate the proton pump inhibitor pantoprazole (PTZ) with manganese ferrite nanoparticles (MFNs) within an acidity-responsive polymer for enhanced ferroptosis and cGAS-STING activation mediated immunotherapy. This assembly (PTZ/MFNAs) facilitates tumor accumulation through the enhanced permeability and retention effect while initially restricting the release of metal ions. Upon reaching the tumor site, PTZ release increases intracellular acidity, which further triggers assembly disintegration, accelerates the release of iron and manganese ions, and neutralizes the extracellular microenvironment to alleviate immunosuppression. The released manganese ions synergistically collaborate with iron ions to amplify reactive oxygen species (ROS) generation for ferroptosis while activating the cyclic guanosine monophosphate-adenosine monophosphate synthase-stimulator of interferon genes (cGAS-STING) pathway, stimulating innate immunity. This potentiation of innate immunity, coupled with the reversal of TME immunosuppression, collectively and effectively inhibits tumor growth and metastasis. Therefore, the PTZ/MFNAs co-delivery system represents a promising pH-modulation strategy to enhance iron/manganese ions-mediated ferroptosis and cGAS-STING activation-induced immunotherapy.",

Many studies indicate that a healthy diet can improve cognitive health and reduce the risk of Alzheimer-type pathogenesis. Plant-based products were tested in hippocampal explants for amplifying the ALP component cathepsin B (CatB), a protease reported to reduce proteinopathy and synaptopathy. Proof-of-concept experiments also tested Panax quinquefolius extract (PanQ) for improving cognitive function in aging rats. Among the natural extracts tested, PanQ emerged as the most effective for increasing the active CatB isoform in correspondence with enhanced levels of synaptic proteins and the autophagy marker LC3-II. PanQ also increased synaptic resilience in a model of lysosomal stress and improved cognitive performance in 20-month-old rats. PanQ-mediated ALP enhancement implicates the proteostasis network in synaptic and cognitive maintenance mechanisms. This study also points to synaptic resiliency as an important factor underlying the influence of dietary components on cognitive health. Panax quinquefolius (PanQ) enhanced cathepsin B (CatB) in hippocampal explants. The CatB modulation corresponded with enhanced synaptic and autophagy markers. PanQ improved synaptic resilience in the chloroquine (Cqn) model of lysosomal stress. Age-related cognitive deficit was reduced by PanQ supplementation in Fischer rats.",
"41450945": "ID: 41450945\nTitle: Modulation of viral replication, autophagy and apoptosis by induction and mutual regulation of transcription factors EB and E3 during coronavirus infection.\nAbstract: Viral invasion and replication in cells significantly impact lysosome structure and function. By sensing changes in the lysosome status, cascades of cellular responses are triggered to maintain lysosomal homeostasis. Two key regulators, transcription factors EB (TFEB) and E3 (TFE3), play essential regulatory roles in these processes by shuttling between the cytoplasm and the nucleus. In this study, we report that infection of cells and/or chickens by gammacoronavirus infectious bronchitis virus (IBV), human betacoronavirus OC43 (HCoV-OC43), and alphacoronavirus porcine epidemic diarrhea virus (PEDV) upregulates the expression of TFEB/TFE3 as well as their downstream targets, and induces the lysosomal stress response. Knockdown of TFE3 alone or together with TFEB demonstrated a pronounced role played by TFE3 in regulating viral replication, virus-induced autophagy and apoptosis in cells infected with the three viruses, and a synergistic effect of TFEB and TFE3 in cells infected with IBV and HCoV-OC43. Furthermore, inhibition of the biosynthetic secretory pathway with brefeldin A (BFA) demonstrated that the release of HCoV-OC43 is mainly via the lysosomal pathway. This study provides novel insights into the functional roles of the lysosomal biogenesis and stress response in coronavirus replication and virus-host interactions.",
"41452570": "ID: 41452570\nTitle: Emerging Anti-Cancer and Repurposed Therapies for Overcoming Multidrug Resistance in Lung Cancer.\nAbstract: Multidrug resistance (MDR) still constitutes a significant barrier to the effective treatment of lung cancer and makes a significant contribution to the poor clinical results. MDR is explained by a set of mechanisms; increase of drug efflux, metabolism, increase of DNA repair potential, inhibition of apoptotic signals, mutation or post-translational modification of drug targets. These cell intrinsic mechanisms are even aggravated by tumour-microenvironment-induced factors, epigenetics dysregulation, survival of cancer stem cells and intratumour heterogeneity, which has made resistance highly adaptive and multifactorial. In order to address this complexity emerging therapeutic strategy is dual. The former element deals with new targeted agents which are able to counter an oncogene-mediated resistance. These include next-generation tyrosine kinase inhibitors (TKIs), KRAS12C inhibitors, bispecific antibodies including ivonescimab, and they all are specific to inhibit predominant signalling cascades that promote tumoral proliferation and resistance. The second element is drug repurposing whereby it exploits already established pharmacological drugs with already a clear safety record to attack non-oncogenic vulnerabilities linked with MDR. Pharmacological modulators of autophagy including statins, disulfiram, and lysosomotropic agents (e.g., chloroquine) target metabolic vulnerabilities such as mitochondrial bioenergetics and redox homeostasis. By mitigating oxidative stress and immune evasion, these compounds act as chemo sensitizers that potentiate the efficacy of tyrosine kinase inhibitors (TKIs) and immunotherapies, effectively overcoming adaptive drug resistance. Real-time monitoring of resistance evolution can be achieved with liquid biopsies, such as circulating tumor DNA and exosomal cargo, whereas MDR-related biomarkers can be used to stratify a patient. Analytical models that are built using artificial-intelligence also guide rational combination-therapy design and the chosen selection of treatments that are personalized. Also, inhalable nano formulations and targeted drug-delivery systems optimize the bioavailability of the formulation by pulmonary determination and ameliorates the systemic toxicity. A combination of these therapeutic approaches will provide a more accurate and flexible way of conquering MDR in lung cancer.",

This study investigated the impact of polystyrene microplastics (PS) on Nile tilapia (Oreochromis niloticus) macrophages and explored metabolic interventions to reverse PS-induced damage. PS exposure increased tilapia susceptibility to Streptococcus agalactiae infection, reducing fish survival. PS accumulated in head kidney macrophages, impairing phagocytosis, altering cytokine expression, elevating oxidative stress and malondialdehyde levels, and suppressing T-cell proliferation. Transcriptomics revealed PS dysregulated lysosomal pathways, reducing lysosomal membrane permeability and bacterial killing capacity. Metabolomic screening identified arachidonic acid (AA) as the most significantly suppressed metabolite in PS-exposed macrophages. Exogenous AA administration restored macrophage function including phagocytosis, cytokine expression, oxidative stress, enhanced lysosomal integrity, improved bactericidal activity, and increased survival during S. agalactiae challenge in PS-exposed fish. AA also reversed PS-induced transcriptional dysregulation of lysosomal genes. These results demonstrate that AA rectifies PS-induced macrophage dysfunction and lysosomal impairment, supporting its potential as a dietary supplement to mitigate microplastic immunotoxicity in aquaculture.",

MNPs can also adsorb other contaminants present in aquatic environments, and there is limited information on exposure scenarios involving MNP and pesticide mixtures. Ultraviolet (UV) radiation and chemical oxidation of MNPs can affect the sorption properties of MNPs and chemicals, thus altering the exposure and effects on fish. Our study investigated the toxicity and bioaccumulation of a lindane and dichlorodiphenyldichloroethylene (DDE) mixture adsorbed onto pristine and weathered polyethylene (PE) MNPs. Three different PE MNP types were used: microplastics (2-10 \u03bcm), oxidized microplastics (10-15 \u03bcm), and a MNP mixture (0.2-9.9 \u03bcm), and additionally each type was UV-aged for comparisons. RTgutGC cells, derived from rainbow trout (Oncorhynchus mykiss) intestine, were used to evaluate the role of the particle type on pesticides bioaccumulation and toxicity. Results showed that UV aging did not affect the agglomeration in solution but decreased the MNP's capacity to adsorb the pesticides (i.e., non-aged adsorbed 35% and 69% and UV-aged adsorbed 9.7% and 63% of lindane and DDE, respectively) likely due to a shift in MNPs hydrophobicity and consequently reduced the cytotoxicity of the pesticide MNPs mixture. Nanoplastics induced approximately 20% more lysosomal damage than microplastics, suggesting a distinct toxicity mechanism. Fluorescently labeled MNPs accumulated in intestinal cells which confirmed the internalization. Finally, bioaccumulation of DDE decreased approximately 2 to 8-fold in cells coexposed with all particle types, although lindane was not detected in the cells. Overall, our study indicated that MP and NPs reduce bioavailability of pesticides, but UV aging and particle fragmentation to nano size increased their bioaccumulation and toxicity in fish intestinal cells.",

Surface-charged nPS variants (cationic, anionic, and neutral) show distinct biodistribution patterns, yet the mechanisms underlying their systemic damage remain incompletely understood. This study aimed to investigate the systemic injury mechanisms of nPS with different surface charges. Mice were exposed to fluorescently labeled cationic (amino-modified), anionic (carboxyl-modified), and neutral nPS via drinking water (25\u00a0mg/mL) for 3\u00a0weeks. Tissue distribution was analyzed using fluorescence microscopy; pathological changes were assessed via hematoxylin-eosin (HE) staining; metabolic perturbations were detected by metabolomic profiling. Mechanistic investigations were performed using metabolomics, flow cytometry, and molecular assays in AML12 hepatocytes and vascular endothelial cells. Fluorescence microscopy showed neutral nPS accumulated in the vascular endothelium of the stomach, intestine, and lung via passive diffusion, while cationic/anionic nPS penetrated hepatic sinusoids through charge-mediated interactions. HE staining revealed severe liver injury, with no significant abnormalities in other tissues. Metabolomic profiling indicated disrupted hepatic amino acid and lipid metabolism, depleted antioxidants (e.g., vitamin E and glutathione), and induced oxidative stress (evidenced by elevated hydroxy fatty acids). In hepatocytes, nPS-induced endoplasmic reticulum (ER) stress triggered excessive reactive oxygen species (ROS) production, inhibiting SLC7A11-mediated cystine uptake and glutathione synthesis, leading to disulfide stress (\u03b2-actin disulfide mispairing) and ferroptosis (GPX4 inactivation and iron accumulation). In contrast, neutral nPS induced endothelial cell senescence via phagolysosome dysfunction, causing lysosomal membrane permeabilization and \u03b2-galactosidase release. This study identifies a \"charge-specific injury\" paradigm: charged nPS induce hepatocyte ferroptosis via an ER stress-disulfide stress cascade, while neutral nPS trigger endothelial senescence through phagocytic dysfunction. These findings provide critical insights for the biosafety assessment of nanoplastics and identify potential targets for preventing plastic pollution-related liver diseases.",
"41533007": "ID: 41533007\nTitle: PLGA nanoparticles restore acidic pH and degradative function to compromised lysosomes with Cy3-labeling providing enhanced tracking to lysosomes.\nAbstract: Lysosomal dysfunction and elevated lysosomal pH are hallmark features of age-related neurodegenerative diseases including age-related macular degeneration (AMD), Alzheimer's disease (AD), and Parkinson's disease (PD). Restoring lysosomal acidity is important for maintaining enzymatic degradation, preventing protein aggregation, and reducing cellular waste accumulation in degenerating tissues. Acidic nanoparticles represent a promising therapeutic strategy to normalize lysosomal pH; however, accurate monitoring of their delivery, retention, and dosage is critical for rigorous evaluation. To address this, we developed fluorescently labeled poly(d,l-lactide-co-glycolide) (PLGA) nanoparticles conjugated with Cyanine3 amine (Cy3). Nanoparticle uptake was systematically optimized, achieving over 90% delivery to lysosomes of induced pluripotent stem cell-derived retinal pigment epithelial (iPS-RPE) cells, although uptake rates varied among adjacent cells. Once internalized, nanoparticles demonstrated remarkable stability, with no detectable change in concentration, distribution, or size for at least 28 days. iPS-RPE cells exhibited higher nanoparticle internalization compared with the ARPE-19 cell line and optic nerve head astrocytes. The capacity of the nanoparticles to restore function to stressed lysosomes was confirmed by their ability to reacidify lysosomes, restore cathepsin B activity, and increase the levels of active cathepsin D. The nanoparticles also reduced the levels of LC3II in astrocytes treated with chloroquine, indicating that they can also restore autophagy rates. In summary, this study demonstrates the value of Cy3 labeling for enhanced nanoparticle tracking to lysosomes. The findings also identify PLGA nanoparticles as powerful tools for restoring degradative lysosomal function and autophagy in cells undergoing lysosomal stress.NEW & NOTEWORTHY Tools that restore acidic pH in compromised lysosomes can enhance autophagy and waste clearance in degenerative disorders characterized by excessive accumulation. Here, we describe the synthesis of lysosome-targeted nanoparticles composed of poly(d,l-lactide-co-glycolide) (PLGA) polymers covalently bound to the fluorescent dye Cyanine3 amine (Cy3). These Cy3-PLGA nanoparticles enable precise tracking of lysosomal delivery and demonstrate sustained long-term retention within lysosomes, supporting their potential for future applications aimed at restoring lysosomal pH in aging and degenerating diseases.",
"41554207": "ID: 41554207\nTitle: Transcriptomic and functional profiling reveal autophagy inhibition and persistent bioenergetic collapse following parallel photodamage to lysosomes and mitochondria.\nAbstract: Photodynamic therapy (PDT) using 1,9-dimethyl methylene blue (DMMB) induces coordinated mitochondrial and lysosomal damage and results in strong cellular death induction. However, the underlying transcriptional regulation in response to DMMB remains elusive. We compared the transcriptome response of photoactivated DMMB (paDMMB) to the gene signature triggered by autophagy-modulating agents: rapamycin (an autophagy activator) and bafilomycin A1 (an autophagy inhibitor). Transcriptome analysis revealed a pronounced transcriptomic response to paDMMB, with 884 differentially expressed genes (DEGs), compared to 291 for bafilomycin and 154 for rapamycin. paDMMB treatment upregulated genes associated with autophagy, mitochondrial stress responses, and proteostasis, while downregulating genes involved in miRNA processing and lipid catabolism. Rapamycin treatment downregulated amino acid biosynthesis pathways, while upregulating processes associated with nutrient starvation. Conversely, bafilomycin treatment upregulated genes related to lipid metabolism, while suppressing cytoskeletal programs. We observed that approximately 80% of bafilomycin DEGs also changed in paDMMB-treated cells, and about 96% of these shared genes showed concordant regulation. This suggests that the paDMMB molecular signature is consistent with the inhibition of autophagic flux. Among the several biological processes affected by paDMMB, mitochondrial-related processes were enriched. To determine whether the acute transcriptome changes caused by paDMMB led to persistent functional effects, we stimulated cells with DMMB and assessed mitochondrial respiration after a recovery period. paDMMB reduced basal respiration, ATP production, proton leak, and maximal respiration. These effects were not further altered by bafilomycin co-treatment but were markedly exacerbated by rapamycin. Collectively, we show that paDMMB leads to a transcriptome rewiring, closely resembling autophagy inhibition with a sustained mitochondrial dysfunction. These findings provide a valuable resource to understand the interplay between DMMB-induced lysosomal stress, transcriptional regulation, and PDT.",
"41572406": "ID: 41572406\nTitle: Macrophage surface protein Mac-2 mediates inflammatory and stromal stress pathways in doxorubicin-induced cardiac injury.\nAbstract: BACKGROUND: Doxorubicin (DOX) cardiotoxicity is a major complication of cancer therapy and involves macrophage-driven inflammation and myocardial remodeling. The macrophage surface protein Mac-2 (galectin-3) is upregulated in cardiac injury, but its role in regulating macrophage function and downstream injury pathways remains undefined. METHODS: We used CRISPR/Cas9-engineered Mac-2-null macrophages to evaluate chemotaxis, cytokine gene expression, and lysosomal stress signaling in vitro. To examine paracrine injury mechanisms, we performed co-culture assays with cardiomyocytes and fibroblasts. In vivo, we studied homozygous Mac-2-mutant mice and used CD45.1/CD45.2 bone marrow transplantation with lineage tracking to define hematopoietic versus stromal contributions to DOX-induced inflammation, apoptosis, fibrosis, and systolic dysfunction. RESULTS: Doxorubicin induced Mac-2 and inflammatory transcripts (Il6, Tnf, Ccl2) in wild-type macrophages, whereas Mac-2 knockout reduced DOX uptake, chemotaxis, and cytokine induction. In co-culture, DOX-treated WT macrophages increased caspase-3/7 activity in cardiomyocytes and phospho-TFEB in fibroblasts, both attenuated with Mac-2 deletion. In vivo, Mac-2-null mice exhibited less cardiac inflammation, apoptosis, and fibrosis with preserved systolic function and reduced mortality. Bone marrow transplantation demonstrated that hematopoietic Mac-2 suppressed cardiac Tfeb and upregulated Sqstm1 and Tgfb1, enhancing inflammatory and apoptotic responses, whereas Mac-2-deficient marrow restored Tfeb, limited Sqstm1/Tgfb1, and protected cardiac function. CONCLUSIONS: Mac-2 promotes DOX-induced cardiac injury by facilitating inflammatory activation in macrophages, driving fibroblast lysosomal stress via TFEB and SQSTM1, and augmenting caspase-3\u2013associated apoptosis in cardiomyocytes. Loss of Mac-2 in hematopoietic cells reduces inflammation, fibrosis, and systolic dysfunction in vivo.",

Nanoparticle-bound bile acids (BAs) and apical sodium-dependent bile acid transporter (ASBT) mediate this fast absorption of PSNPs. In the liver, PSNPs block CYP7A1 degradation by disrupting lysosome biogenesis, which promotes BA synthesis and increases colitis susceptibility of mice by reducing Lactobacillus and increasing Enterobacteriaceae. Significant sexual dimorphism is unexpectedly discovered after PSNP treatment, where male mice are more sensitive than females due to the higher ASBT expression on enterocytes in males.

Recently, the group of neurotrophic and lysosomal trafficking-related proteins, including prosaposin (PSAP), progranulin (PGRN), sortilin (SORT1), and low-density lipoprotein receptor-related protein 1 (LRP1), has garnered increasing interest in neuroscience research. The aim of this study was to profile the post-mortem levels of PSAP, PGRN, SORT1 and LRP1, and to determine whether these biomarkers could serve as diagnostic tools for mechanistic stratification in forensic neuropathology and medico-legal investigations. The study involved a total of 40 cases, individuals with head injuries (n\u202f=\u202f20) suspected to be the cause of death and control atraumatic cases of sudden death (n\u202f=\u202f20) due to cardiopulmonary reasons. Serum and cerebrospinal fluid (CSF), were collected approximately 24\u202fh post-mortem and analyzed through ELISA testing. Brain specimens were obtained during forensic autopsies and subjected to immunohistochemical staining. We observed the elevated concentration level of PSAP in CSF, and the elevated concentration level of PGRN within serum and CSF. In the frontal cortex, anti-SORT1 and anti-LRP1 immunostaining revealed a general homogenization of the reaction in the study group. The molecular and cellular evidence suggests lysosomal trafficking disruption as central element of fatal TBI. The redistribution of SORT1 and LRP1, together with CSF-specific PSAP elevation and systemic PGRN increase, support a model in which neuronal lysosomal stress, receptor trafficking breakdown, and systemic release of lysosomal proteins are intertwined. The potential use of PSAP, PGRN, SORT1, and LRP1 assays offers an novel tool for research regarding TBI diagnosis and pathogenesis.",

Beyond classical risk factors, persistent low-grade inflammation and fibrotic remodeling contribute to adverse outcomes that current treatments fail to fully prevent. Growing evidence highlights the glyco-inflammatory axis-the interplay between protein glycosylation-dependent signaling and inflammation-as an underappreciated contributor to residual atherosclerotic risk, largely because current therapeutic strategies do not directly target glycan-mediated mechanisms. Within this framework, Galectin-3 (Gal-3), a \u03b2-galactoside-binding lectin, has emerged as a key molecular hub linking metabolic stress, lysosomal dysfunction, and vascular remodeling. By recognizing specific glycan motifs on immune and stromal cells, Gal-3 orchestrates macrophage activation, endothelial dysfunction, and extracellular matrix deposition, thereby amplifying chronic inflammation and fibrosis. Elevated circulating Gal-3 levels are associated with plaque vulnerability and major adverse cardiovascular events, independent of lipid or C-reactive protein levels. Experimental Gal-3 inhibition reduces inflammation and fibrosis in preclinical models, supporting its therapeutic potential. This review integrates mechanistic, translational, and clinical evidence to propose Gal-3 as a missing link between intracellular stress responses and extracellular fibro-inflammatory remodeling. Targeting the Gal-3-mediated glyco-inflammatory axis may represent a novel strategy to overcome residual cardiovascular risk and achieve comprehensive vascular protection in the post-statin era.",

This study aimed to evaluate the therapeutic potential of two dietary antioxidants-astaxanthin and Garcinia indica (kokum)-in modulating hepatic redox status, lysosomal function, and metabolic gene expression in a murine model of diet-induced NAFLD. A total of 120 male Swiss Webster mice were allocated into control and steatotic groups, followed by a 90-day supplementation period with astaxanthin, kokum, or their combination. Liver tissue was collected post-supplementation for biochemical, antioxidant, and qRT-PCR analyses. Outcomes included lysosomal enzymes activities, superoxide dismutase (SOD), GSH, vitamin C, total polyphenols, DPPH radical-scavenging activity, and total antioxidant capacity (TAC). NAFLD induced marked oxidative stress, lysosomal overactivation, and alteration of antioxidant-related gene expression. Combined supplementation restored GSH, enhanced TAC, reduced lysosomal stress markers, and significantly upregulated nuclear factor erythroid 2-related factor 2 (Nfe2l2) while downregulating fatty acid synthase (FASN) and partially rescuing lipoprotein lipase (LpL). Correlation analyses revealed strong associations between antioxidant capacity, lysosomal function, and transcriptional regulation, supporting the therapeutic relevance of combined antioxidant therapy for concurrent redox and lysosomal dysregulation in NAFLD. These findings underscore the therapeutic potential of targeting redox and cellular degradation pathways with antioxidant-based interventions to re-establish hepatic metabolic balance in NAFLD and related disorders.",

Traditionally, its pathogenesis has been attributed primarily to an imbalance in the number and activity of osteoblasts and osteoclasts. However, emerging evidence has uncovered a critical bidirectional interdependence between the integrity of the extracellular matrix (ECM) and the functional homeostasis of the intracellular lysosomal system-an axis increasingly recognized as the \"bone matrix-lysosome crosstalk.\" Despite its apparent importance, the central role of this regulatory circuitry in bone homeostasis and the mechanisms through which it becomes disrupted under pathological conditions remain insufficiently defined.This review synthesizes current advances regarding the cell type-specific functions of lysosomes across distinct bone cell populations and further examines how the ECM, as a dynamic microenvironment, exerts reciprocal control over lysosomal biogenesis and activity. We highlight how the biochemical composition and biophysical properties of the ECM govern lysosomal acidification, metabolic coupling, and degradative capacity with remarkable precision. During the progression of osteoporosis, structural compromise of the ECM and lysosomal dysfunction reinforce one another, establishing a self-amplifying pathological loop that accelerates the collapse of the bone microenvironment. Recognizing this reciprocal deterioration, we propose that restoring the dynamic equilibrium of the \"ECM-lysosome axis\" may represent a mechanistic pivot for reversing osteoporotic degeneration. Interventions targeting lysosomal function, reconstructing the bone ECM, and employing nanomedicine-enabled organelle-specific delivery hold particular promise for advancing precision therapeutics in osteoporosis.",

The antibody-mediated targeted drug delivery systems are especially antibody\u2013drug conjugates (ADCs) and antibody-conjugated nanoparticles (ACNPs) have become the game changers in the age of precision oncology. By taking advantage of the selectivity of monoclonal antibodies, these platforms preferentially target tumor-associated antigens (TAAs) including HER2, TROP-2, HER3 and LIV-1, which avoids off-target toxicity and overcomes drug resistance. This review presents a detailed discussion of the principles of design, mechanisms and clinical advancements of ADCs and ACNPs in the treatment of BC. Major advances are in the field of advanced linker technology, site selective conjugation techniques, and novel payloads that have potent antitumor effects. A number of new-generation ADCs have demonstrated promising clinical results, especially in HER2-positive and triple-negative forms of the BC. Moreover, nanocarrier-based drug delivery systems like trastuzumab-functionalized liposomes or polymeric nanoparticles are more advantageous in drug loading and release, as well as tumor penetration. In spite of this progress there are still several challenges including heterogeneity of tumor antigens, immunogenicity and off-target toxicity which hinder clinical translation. Bispecific antibodies, dual-payload ADCs, and patient-specific antigen profiling are some of the strategies under research to improve the precision of therapeutic treatment. With the application of molecular targeting and drug delivery innovation, the biology of antibody-mediated systems has enormous potential to transform the standard of treatment of BC and pave the way to customised medicine. Antigen selection, rational linker-payload design, and biomarker-directed patient stratification. In BC, ADC-led antibody-mediated delivery is setting therapeutic delivery action, and after all, toxicity management and mitigation of resistance are core clinical factors in success.",

While strong metal-support interaction (SMSI) is an established strategy to tailor the morphology and electronic properties of supported metal catalysts, the role of interfacial charge redistribution in SMSI formation remains poorly understood and rarely leveraged. Here, we report a dual-stimuli approach that combines pH modulation with ultrasonication to mediate SMSI construction in aqueous solution through dynamic Fermi level tuning. By leveraging in situ pH-driven charge redistribution at the metal-support interface, we achieve controllable SMSI encapsulation of metal nanoparticles, as verified by electrochemical analysis, work function measurements, and x-ray-based techniques. The resulting catalysts exhibit tunable SMSI features and deliver enhanced activity and selectivity in hydrogenation reactions. This work establishes a facile strategy to modulate catalyst structure and electronic properties by exploiting Fermi level variation as a driving force, thereby advancing rational SMSI design and catalytic performance across diverse environments.",

To disrupt this metabolic adaptability, we herein engineer a homotypic membrane-camouflaged nanomedicine capable of hypoxia-responsive cascade drug release and enhanced tumor accumulation. The resulting nanomedicine performs a hypoxia-induced phase transition that first liberates glucose oxidase to intensify oxygen deprivation and subsequently triggers burst release of chloroquine. Such a design of self-amplified relay drug release ensures effective starvation induction and precise lysosomal alkalization, thereby shutting down lysosome-mediated nutrient recycling. In a xenograft orthotopic PDAC model, this nanomedicine achieves 9.75-fold increase in tumor accumulation, robust tumor inhibition of 92.8%, and an elevated survival rate of 80% with favorable biosafety. Collectively, our findings highlight lysosomal disruption as a therapeutic lever to potentiate starvation therapy and provide a clinically actionable nanoplatform to enhance metabolic interventions for other metabolically vulnerable malignancies.",

This targeted microenvironment, centered on the interaction between epithelial components and their immediate surroundings, is intricately linked to the early progression and progression of lung cancer. Due to the prominent advances in nanotechnology recently, the interactions between nanoparticles and humans are inevitable. However, the role and precise mechanism of nano-bio interactions in PEM and their contributions to lung cancer are yet to be elucidated. In this study, we unexpectedly discovered that pulmonary exposure to silicon nanoparticles (SiNPs), a significant inhaled pollutant nanoparticle which was previously involved in inflammatory and fibrosis responses in the lung, intriguingly inhibited the early progression and metastasis of lung cancer in both in vitro and in vivo models. Mechanistically, SiNPs disrupted lysosomal function in lung epithelial cells, impaired the autophagosome-lysosome degradation pathway, and reduced Extracellular vesicles (EVs)-mediated communication between lung epithelial cells and lung cancer cells. An obvious decrease in EVs and their cargo, particularly miR-296-3p, within the tumor microenvironment heightened the susceptibility of lung cancer cells to ferroptosis. Our findings suggest that pulmonary exposure to SiNPs inhibits lung cancer early progression and metastasis, with the Atg5/EVs/miR-296-3p axis playing a critical role in this process. This study offers new insights into the mechanisms linking nano-bio interaction reshaped pulmonary epithelial microenvironment and lung cancer progression.",

Recent findings suggest that abnormal aggregation of pathogenic proteins within the nervous system may contribute to the neurotoxicity induced by nanoplastics, yet the molecular mechanisms regulating this pathological cascade remain unclear. Here, we used immature mice as an experimental model to represent infants and young children who are at higher risk of nanoplastics exposure, to elucidate the molecular mechanisms underlying neurotoxicity induced by exposure to polystyrene nanoplastics (PS-NPs) during early life. The results showed that environmentally relevant doses of PS-NPs penetrated the brains of immature mice and induced behavioral and emotional disorders. Proteomic analysis identified the mTOR signaling pathway as a candidate pathway responding to PS-NPs exposure in the immature mouse brain. Rapamycin intervention and quantitative validation further demonstrated that PS-NPs exposure upregulated mTOR signaling, thereby leading to lysosomal dysfunction and a blockade of autophagic flux, which in turn disrupted proteostasis and ultimately caused neurotoxicity. Furthermore, treatment with sodium 4-phenylbutyrate (4-PBA) confirmed that proteostasis imbalance, characterized by activation of the unfolded protein response, was a direct driver of this neurotoxicity. Notably, both rapamycin and 4-PBA treatments alleviated neurotoxicity resulting from PS-NPs exposure by restoring proteostasis. Together, these findings highlight dysregulation of the autophagy-lysosome pathway mediated by mTOR as a central mechanism of PS-NPs-induced neurotoxicity in immature mice and suggest lysosomal regulation for proteostasis remodeling as a prospective therapeutic strategy against neurological hazards related to nanoplastics.",
"41653942": "ID: 41653942\nTitle: Engineering lysosomal collapse for cancer therapy: From mechanistic insights to nanotherapeutic innovations.\nAbstract: Lysosomes are markedly altered in tumor cells, exhibiting increased number and size, enhanced acidification, elevated cathepsin activity, and remodeled ion channel composition. These adaptations confer heightened degradative capacity and metabolic plasticity, supporting tumor survival, progression, and therapeutic resistance. Beyond their classical catabolic role, lysosomes function as central hubs for nutrient sensing, stress adaptation, and transcriptional regulation, making lysosomal integrity an emerging vulnerability in cancer therapy. This review aims to elucidate the therapeutic potential of inducing lysosomal collapse as an anticancer strategy, with a particular focus on recent nanotherapeutic approaches designed to precisely disrupt lysosomal function. This study systematically summarizes current knowledge on lysosomal structure and function in tumor cells and analyzes preclinical studies that exploit lysosomal destabilization for cancer treatment. Nanotherapeutic strategies targeting lysosomes are categorized according to their underlying mechanisms, including gas generation-mediated blasting, osmotic swelling, fiber-induced expansion, oxidative membrane damage, and direct phospholipid bilayer disruption. For each strategy, the design rationale, mechanistic basis, and representative experimental outcomes are critically evaluated. Accumulating evidence demonstrates that controlled lysosomal membrane permeabilization or rupture can effectively induce tumor cell death, reverse drug resistance, suppress metastasis, and alleviate immune evasion. Nanotherapeutic platforms enable spatially and temporally precise lysosomal disruption, enhancing antitumor efficacy while minimizing off-target toxicity. Comparative analysis reveals distinct advantages and limitations among different lysosome-targeting strategies, underscoring the importance of rational nanomaterial design. These advances establish lysosomes as central regulators of tumor biology and promising therapeutic \"death triggers\". Lysosome-targeted nanotherapeutics represent a powerful and versatile approach for overcoming major barriers in cancer treatment, offering new opportunities for precise, effective, and mechanism-driven anticancer interventions.",

Conjugation of ATG8s to single membranes (CASM) is a noncanonical LC3\u2011lipidation pathway activated by various stressors, distinct from canonical autophagy. We previously showed that TBT reduces lysosomal acidity and inhibits autophagy in SH-SY5Y cells. Furthermore, we observed TBT-induced LC3-II accumulation, which was reduced by bafilomycin A1, and tubular LC3-positive structures as hallmarks of CASM. In this study, we investigated whether TBT activates CASM. TBT (700\u00a0nM) induced LC3-II accumulation, which was completely blocked by bafilomycin A1 in SH-SY5Y and HeLa cells. Unlike autophagy, TBT induced LC3-II accumulation even under class III PI3K inhibition by wortmannin and in FIP200-knockout cells. Salmonella effector protein SopF, which inhibits V-ATPase-ATG16L1 association required for CASM, inhibited TBT-induced LC3-II accumulation. In FIP200-knockout cells, TBT induced LC3 accumulation on lysosomes, the primary CASM target. TBT also promoted nuclear translocation of transcription factor EB (TFEB) in a SopF-sensitive manner. Together, these results identify CASM as a lysosomal stress response to TBT, induced via the V-ATPase-ATG16L1 axis, leading to TFEB activation. This mechanism provides a toxicological framework for understanding xenobiotic-induced lysosomal adaptations.",

Although environmentally aged MNPs predominate, their developmental toxicity remains poorly understood. We demonstrate that both pristine and aged polystyrene nanoplastics (PSNPs) induce abnormal lipid accumulation and impair early development in zebrafish larvae. Lipidomics revealed aged PSNPs significantly increased triglycerides via disrupted glycerophospholipid metabolism. Mechanistically, aged PSNPs did not alter LC3-II/LC3-I ratios but upregulated RAB7 and p62 while downregulating lysosomal biogenesis regulator TFEB. They also reduced ATG5, essential for autophagosome formation via LC3 lipidation. These molecular alterations, together with lysosomal inhibition assays, functionally support lysosomal dysfunction as a key constraint on lipophagy. This impairment inhibits lipid utilization, promotes accumulation, and disrupts development. Critically, aged PSNPs caused stronger disruption than pristine particles despite both interfering with lipophagy. Our study provides mechanistic insights into the developmental toxicity of UV-aged PSNPs in zebrafish, highlighting the importance of considering aging-related changes in nanoplastic risk evaluation. SYNOPSIS: Aged nanoplastics exacerbate developmental toxicity in zebrafish by suppressing lipophagy to drive lipid accumulation, underscoring ecological risks in aquatic systems.",

The progression of tumors is influenced by both intrinsic changes within cancer cells and the tumor microenvironment (TME), which is a dynamic collection of stromal cells, immune infiltrates, extracellular matrix, and soluble mediators that together encourage immune suppression, angiogenesis, and resistance to treatment. Antibody-conjugated nanoparticles (ACNPs) combine antibody-mediated molecular recognition with nanoscale drug delivery systems to selectively target malignant cells and important components of the TME. In preclinical and early clinical studies, representative ACNP classes, including monoclonal antibodies or antibody fragments conjugated to liposomes, polymeric nanoparticles, metallic cores, or lipid-polymer hybrids, have exhibited enhanced tumor association and context-dependent intratumoral delivery, as well as the ability to modulate suppressive TME elements such as M2-like tumor-associated macrophages and cancer-associated fibroblasts. Nonetheless, clinical translation is impeded by significant biological and translational obstacles, such as tumor heterogeneity, restricted tissue penetration, swift elimination by the mononuclear phagocyte system, immunogenicity-associated safety concerns, and challenges in manufacturing and scaling up. In this paper, we critically examine ACNP design strategies, compare antibody formats and conjugation chemistries, and compile mechanistic evidence from in vitro, in vivo, and early clinical studies published up to 2025. We further investigate ACNP-based combination regimens targeting TME modulation and conclude by delineating translational priorities and practical design considerations necessary for achieving consistent therapeutic efficacy in heterogeneous human tumors.",

Impaired cellular waste clearance via autophagy-lysosomal pathways have been implicated in photoreceptor death, but the spatiotemporal dynamics of these processes during degeneration remain poorly understood. Using the rd10 mouse model of retinitis pigmentosa, we characterised autophagy-lysosomal dysfunction at key stages of photoreceptor degeneration (postnatal day P17, P22, P35) through super-resolution imaging of RFP-EGFP-LC3 reporter mice, Western blot, and bulk RNA sequencing. Autophagosome and autolysosome numbers were significantly elevated across all photoreceptor compartments (inner/outer segments, outer nuclear layer, outer plexiform layer) at P17, prior to significant photoreceptor nuclei loss. Autophagosome and autolysosome size progressively increased from P22 onwards, suggesting accumulation of unprocessed intracellular waste. Molecular analyses revealed downregulation of mTOR protein, upregulation of autophagy-related genes, and increased lysosomal processes from P17. These histological and molecular findings are consistent with early autophagy induction followed by overwhelmed degradative capacity. Our findings identify autophagy-lysosomal change as an early event in photoreceptor loss in the rd10 model, revealing a critical therapeutic window for mutation-independent interventions targeting cellular clearance pathways in inherited retinal degenerations.",

To address this, we developed subcellular target-tracking fluorescent-visualization-based interaction screening (SubTrack-FVIS), a platform combining super-resolution imaging with target-specific fluorescent tagging. SubTrack-FVIS first maps nanoscale spatial distributions of drug targets within living cells, then screens compound libraries to identify molecules specifically binding to target-enriched domains, and finally quantifies drug-target interactions through super-resolution imaging tracking. Compared to traditional toolbox, SubTrack-FVIS reduces off-target effects by evaluating compound binding within native subcellular architectures. When applied to the lysosomal vacuolar H+-ATPases (V-ATPase) subunit, ATP6V1A, a validated anti-cancer target, this approach identified for lysosomal alkalization fluorescent drug (LAFD) as a potent inhibitor. Super-resolution imaging revealed LAFD's dynamic binding to ATP6V1A clusters, enabling real-time visualization of V-ATPase inhibition and subsequent lysosomal destabilization. Crucially, SubTrack-FVIS uncovered LAFD's unique mechanism of blocking autophagosome-lysosome fusion, resolving autophagic flux obstruction at sub-100 nm resolution. This platform establishes a visualization framework for discovering drugs within physiological subcellular contexts while simultaneously decoding their mechanistic impacts, offering application potential for target-centric drug development.",

Herein, we engineer a near-infrared-II (NIR-II) phototheranostic nanoplatform, CAG/FD1080@MM-aTRPV4, for synergistic regulation of microglial function and real-time monitoring of PD pathology. We first encapsulated cycloastragenol (CAG), a bioactive compound derived from Astragalus, into liposomes. These liposomes were then fused with biomimetic microglial membrane-loaded FD1080 photothermal imaging agent, followed by modification with a transient receptor potential vanilloid 4 (TRPV4)-targeting antibody. In vitro studies using \u03b1-syn-treated cultured microglia and in vivo studies in an \u03b1-syn-overexpressing mouse model collectively demonstrate the efficacy of our strategy. It not only enables precise microglial delivery of CAG to reprogram metabolism but also sustains lysosomal function via photothermal activation of the TRPV4/CaMKK\u03b2/AMPK/mTOR pathway, ultimately enhancing phagocytosis. Importantly, the encapsulated FD1080 (for microglial tracking) and an anti-\u03b1-syn-conjugated indocyanine green (anti-\u03b1-syn-ICG) probe enable dual-modality NIR-II photoacoustic-fluorescence imaging, allowing real-time visualization of both microglial dynamics and \u03b1-syn clearance.

However, it remains unclear whether ATP13A2 mutations carried by PD patients contribute to immune dysfunction that exacerbates disease progression. Here, we systematically demonstrate that many ATP13A2 mutations result in a loss-of-expression phenotype. ATP13A2 is highly expressed in macrophages. Myeloid ATP13A2 deficiency causes uncontrolled NLRP3 inflammasome activation driven by lysosomal alkalization and subsequent disrupted mitochondrial homeostasis, rendering mice susceptible to a PD-like phenotype. PD-linked ATP13A2 loss-of-expression mutants fail to restore the ATP13A2 levels required to suppress NLRP3 hyperactivation in ATP13A2-depleted human THP-1 monocytes. Macrophages from a PD patient carrying the ATP13A2 loss-of-expression L927P mutation exhibit excessive NLRP3 activation due to lysosomal-mitochondrial dysfunction. Our findings provide insight into PD pathogenesis, emphasizing genetic factor-driven dysregulated macrophage NLRP3 activation, particularly in ATP13A2 loss-of-expression mutation cases.",

All three causes constitutively activate LRRK2 kinase activity to augment immune responses, enhancing immunity to fight pathogens, but similar mechanisms in the brain increase the vulnerability of dopaminergic neurons to degeneration. Although VPS35 p.D620N possess the highest constitutive increase in LRRK2 kinase activity among known variants in LRRK2 or RAB32, its effects on the immune system remain poorly understood. LRRK2 and Rab32 are highly expressed in myeloid cells including microglia; thus we examined the transcriptomic and functional consequences of Vps35 p.D620N in knock-in mice (VKI). Microglia were isolated from brains of six-month-old VKI mice and were analyzed via single-cell RNA sequencing. Differential gene expression highlighted pathways involved in antimicrobial humoral immune response, lysosomal stress sensing, and phagocytosis. Notably, genes of S100 family proteins, along with lipocalin 2 (Lcn2), were significantly upregulated, and those measures were complimented by immunohistochemistry and quantitative PCR. In contrast, pathways involved in synaptic transmission, neuronal development, and homeostatic immune signaling were downregulated. Peripheral stimulation with lipopolysaccharide amplified microglial activation and phagocytic markers in wildtype mice, and VKI mice also display enhanced morphological activation and increased synaptic engulfment. Collectively, Vps35 p.D620N drives a chronic pro-inflammatory microglial phenotype characterized by heightened innate immune signaling, lysosomal stress, and enhanced phagocytic activity. VKI microglia are sensitized to peripheral immune challenges and may promote synaptic remodeling and neurodegenerative vulnerability in PD. These results provide mechanistic insight into how retromer dysfunction and LRRK2 kinase hyperactivity intersect with microglial biology to influence PD pathogenesis.",

Elucidating the mechanisms underlying PS-induced toxicity and identifying effective interventions to mitigate adverse effects are therefore critically important.

Furthermore, this study revealed that PS-induced ferroptosis in ovarian granulosa cells. Mechanistically, ER\u03b1-mediated PS internalization led to activation of the YAP1-ACSL4 signalling and subsequent lipid peroxidation. Moreover, we demonstrated that glycine effectively alleviate PS-induced ferroptosis by modulating lysosome-dependent ferritin degradation in a PAT1-dependent manner, thereby restoring iron homeostasis. Taken together, these findings revealed that PS exposure triggers ACSL4 overexpression and iron overload in ovarian granulosa cells, whereas glycine restored iron homeostasis via lysosome-mediated ferritinophagy.

An experimental ACP composite was compared with Activa\u2122 BioACTIVE-Restorative, Cention N, and Surefil one \u2122. Calcium (Ca2+), phosphate (PO4 3-), and fluoride (F-) release, along with pH changes, were assessed over 365 days in artificial saliva. Fluoride recharge was performed at six months using a single application of 5000\u00a0ppm sodium fluoride gel, followed by cumulative fluoride re-release measurement for 30 days. The flexural strength and modulus were evaluated at baseline, 6 months, and 12 months. Statistical analysis was conducted using mixed-model ANOVA with post-hoc tests, and flexural strength reliability was assessed using Weibull analysis (\u03b1\u00a0=\u00a00.05). All materials exhibited an initial burst of ion release, followed by a progressive decline (p\u00a0=\u00a00.001). The ACP composite demonstrated the highest early calcium and phosphate release but negligible fluoride release and significant reductions in mechanical properties and reliability after aging. Cention N showed sustained multi-ion release, the greatest alkalizing capacity, and stable mechanical performance. Surefil one\u2122 achieved the highest fluoride release and recharge capacity while maintaining a near-neutral pH and superior mechanical reliability.

"41867743": "ID: 41867743\nTitle: HIV-1 gp120-induced lysosomal stress responses are controlled by TRPML1 redox sensors.\nAbstract: Increased lysosomal stress responses (LSR) are commonly implicated in the pathogenesis of neurodegenerative disorders including HIV-1-associated neurocognitive disorders (HAND). The HIV-1 envelope glycoprotein gp120 causes LSR, increases levels of ferrous iron (Fe2+) in the cytosol and in mitochondria, disrupts the reactive species interactome (RSI), and increases neural cell death. Here, we report that TRPML1, an endolysosome redox-sensitive cation channel, is mechanistically involved in gp120-induced neurotoxicity. TRPML1 was activated by gp120-induced increases in cytosolic reactive oxygen species (ROS) and resulted in release of Fe2+ from endolysosomes in levels sufficient to increase cytosolic levels of Fe2+ and ROS as well as decrease levels of hydrogen sulfide (H2S). Reduced glutathione normally buffers intracellular Fe2+, but gp120 decreased endolysosome glutathione levels and disrupted this regulatory control mechanism thereby promoting TRPML1-mediated Fe2+ efflux from endolysosomes. TRPML1 redox activation led to changes to the RSI in endolysosomes including increased ROS, lipid peroxidation, nitric oxide, and sulfane sulfur as well as decreased H2S. These changes were accompanied by increased cysteine oxidation of luminal proteins and endolysosome deacidification. Pharmacological inhibition of TRPML1 or knocking down expression levels of TRPML prevented these effects. Thus, our findings suggest that TRPML1 redox activation controls gp120-induced endolysosome dysfunction and iron/redox imbalance, and further implicates TRPML1 in the pathogenesis of HAND.",

However, tumor cells exhibit a pronounced adaptive capacity to remodel lysosomal pH, thereby resisting LMP induction by pH-responsive materials and ultimately compromising therapeutic efficacy. To overcome this limitation, we engineered proton-driven \u03c0-\u03c0 stacked copper-phycocyanin nanoparticles (CuPC NPs) designed to selectively promote LMP in tumor cells through their aggregation within acidic lysosomes. Mechanistically, aggregated CuPC NPs directly engage the RIPK3/p-MLKL signaling axis to trigger LMP, thereby orchestrating the synergistic activation of necroptosis, ferroptosis, and cuproptosis. Due to the coordinated induction of multimodal cell death, these pH-responsive CuPC NPs effectively inhibit primary breast tumor growth and suppress pulmonary metastasis. Collectively, our study establishes a strategy for precise modulation of lysosomal function to enhance antitumor efficacy and provides valuable insights into the development of lysosome-targeted nanotherapeutics for tumor treatment.",

Herein, we developed a nano-delivery system, designated as CEL-TPP@siSurvivin/TDNP NPs, consisting of a self-assembled nanocore formed by triphenylphosphine (TPP)-modified celastrol (CEL) and siSurvivin, encapsulated within turmeric-derived nanoparticles (TDNPs), for effective tumor treatment through a combined chemotherapy and gene therapy approach. The TPP modification confers mitochondrial targeting capability to CEL, which acts combinedly with siSurvivin-mediated gene silencing to significantly enhance tumor cell apoptosis. Notably, once the NPs enter cells and become sequestered within lysosomes, they induce the upregulation of the V-ATPase subunits ATP6V1A/ATP6V1G1. It hyperactivates lysosomal proton pumps, driving excessive acidification of the lysosomal lumen, which in turn facilitates NPs escape and ultimately enhances the silencing efficiency of the delivered siSurvivin. Furthermore, in vivo studies validated that the nano-delivery system exhibits potent antitumor efficacy in a 4T1 murine breast cancer model while maintaining a favorable biosafety profile. This study presents a novel strategy to overcome the lysosomal escape challenge in nanomedicine, while also establishing an efficient and low-toxicity delivery platform for combined chemotherapy and gene therapy with promising clinical translation prospects.",

However, the synergistic toxicity of Ps-MPs and PBDEs on female fertility and oocyte quality remains insufficiently characterized. In this study, we established a 28-day oral exposure model in female ICR mice to evaluate the effects of Ps-MPs, PBDE-47, and their co-exposure on ovarian function, oocyte meiotic competence, and reproductive outcomes. Both Ps-MPs and PBDE-47 alone reduced ovarian weight, decreased antral follicles, increased follicular atresia, and markedly lowered ovulation and litter size, whereas co-exposure produced the most severe impairments. At the oocyte level, exposure significantly reduced germinal vesicle breakdown and first polar body extrusion, increased abnormal spindle formation and erroneous kinetochore-microtubule attachments, and suppressed TPX2 expression and \u03b1-tubulin acetylation. Cortical F-actin polarization, spindle migration, and membrane localization of JUNO and ovastacin were also disrupted, indicating widespread defects in meiotic and membrane maturation. Mechanistically, Ps-MPs and PBDE-47 induced a decline in mitochondrial membrane potential, aberrant mitochondrial distribution, excessive lipid accumulation, and Ca\u00b2\u207a imbalance, accompanied by autophagosome accumulation, lysosomal dysfunction, elevated ROS, increased \u03b3-H2AX signals, and enhanced Annexin V labeling, ultimately triggering DNA damage and apoptosis. All alterations were most pronounced under co-exposure. Collectively, Ps-MPs and PBDE-47 synergistically impair female fertility by converging on mitochondrial dysfunction, autophagy-lysosome imbalance, and oxidative stress-mediated DNA damage, leading to substantial reductions in oocyte quality. These findings provide key mechanistic evidence for evaluating reproductive risks associated with real-world mixtures of microplastics and persistent organic pollutants.",
"41906739": "ID: 41906739\nTitle: Dual pathways of TFEB activation under lysosomal stress: ATG conjugation-dependent and -independent modes.\nAbstract: TFEB (transcription factor EB) regulates the expression of autophagy and lysosomal genes, is activated by various cellular stresses, and plays a key role in maintaining cellular homeostasis. Recent work demonstrates that TFEB is activated during lysosomal damage through two distinct mechanisms: ATG conjugation-dependent and -independent. TFEB activation proceeds sequentially through two modes. In the early ATG conjugation-independent mode (Mode I), APEX1 interacts with TFEB in the nucleus, maintaining its transcriptional activity and protein stability. In the later ATG conjugation-dependent mode (Mode II), CCT7 and TRIP6 translocate to lysosomes and interact with TFEB, modulating its phosphorylation and nuclear localization. Moreover, TFEB regulation induced by other cellular stresses-such as oxidative stress, proteasome inhibition, mitochondrial damage, and DNA damage-also involves either Mode I or Mode II. Our findings provide new insights into a unified understanding of TFEB regulation under diverse cellular stress conditions.",
"41912307": "ID: 41912307\nTitle: Assessment of lysosomal drug sequestration and release using fluorescence microscopy.\nAbstract: Lysosomotropism refers to the ability of certain basic lipophilic compounds to accumulate in lysosomes via pH partitioning. Various drugs including anticancer agents are trapped in lysosomes, and this process can prevent such drugs from reaching their primary target, thereby limiting their effectiveness. Strategies aimed at preventing drug sequestration or inducing drug release from lysosomes have garnered considerable interest. Chloroquine is a widely used anti-malarial drug that triggers lysosome membrane permeabilization (LMP) to liberate sequestered drugs from these organelles. In this study, we first evaluate the lysosomotropism of various fluorescent anticancer agents in silico. Next, we outline a simple, fast and robust method for the visualization and quantification of their lysosomal sequestration and release by fluorescence microscopy. The method is used on live cells and consists of two steps:\u00a0(i) visualization of the compounds in lysosomes by analyzing their colocalization with a specific fluorescent lysosomal marker, and (ii) assessment of drug release from lysosomes. Furthermore, we present fluorescence microscopy protocols for monitoring LMP by analyzing the subcellular localization of LGALS3 (Galectin-3), which normally distributes diffusely in the cytoplasm but translocates into lysosomes upon LMP. This can be achieved on fixed cells by detecting endogenous LGALS3 with immunostaining or by the visualization of a transgenic LGALS3-mCherry fusion protein on live cells. Altogether, these methods facilitate qualitative and quantitative fluorescence imaging of lysosomal sequestration and liberation of lysosomotropic drugs.",

Building on our recent biophysical studies confirming the affinity of NO-Cbl for intrinsic factor, this work aimed to investigate the mechanistic basis for the selective anticancer activity of NO-Cbl through the cobalamin transport axis and lysosomal processing. Human cancer cell lines (NIH-OVCAR-3, MCF-7, WM9, and DU145) were cultured and transfected to overexpress transcobalamin II (TCII). Cell proliferation and cytotoxicity were measured using the sulforhodamine B (SRB) assay. TCII-R (CD320) expression was quantified by flow cytometry. The impact of anti-CD320 antiserum and lysosomal alkalization (chloroquine) on NO-Cbl activity was assessed. Antiserum inhibition of the TCII receptor resulted in dose-dependent inhibition of NIH-OVCAR-3 and MCF-7 cell proliferation. Lysosomal alkalinization by chloroquine pretreatment abrogated NO-Cbl-induced cytotoxicity in OVCAR-3 cells. Flow cytometric analysis demonstrated an inverse correlation between TCII-R (CD320) expression (MFI ratio) and NO-Cbl ID50. TCII overexpression significantly reduced NO-Cbl ID50 in NIH-OVCAR-3 cells. NO-Cbl utilizes tumor cell cobalamin transport and processing pathways to deliver nitric oxide selectively to cancer cells. These results, integrated with recent binding studies, validate NO-Cbl as a cobalamin-based targeted anticancer agent with efficacy in tumors expressing high levels of TCII and CD320.",

Although histone deacetylase (HDAC) inhibitors show therapeutic potential, their clinical translation for AD is hampered by poor blood brain barrier (BBB) penetration and an incomplete understanding of their mechanism in A\u03b2 clearance. Here, angiopep2-conjugated nanoparticles (SAHA@LIPO-ANG2) for efficient BBB translocation and delivery of the HDAC inhibitor vorinostat (SAHA) was developed and its underlying mechanisms were validated. Our result demonstrates that SAHA@LIPO-ANG2 potently inhibits HDAC4 nuclear translocation, which was identified as a key upstream event responsible for the transcriptional repression of sodium-hydrogen exchanger 6 (NHE6). Restoration of NHE6 expression rectifies endosomal hyperacidification, thereby rescuing the trafficking and plasma membrane expression of the A\u03b2 clearance receptor, low-density lipoprotein receptor-related protein 1 (LRP1). Furthermore, this HDAC4-NHE6-pH axis modulates the neuroimmune microenvironment to enhance A\u03b2 clearance through multiple synergistic mechanisms: it upregulates phagocytic receptors and recruit microglial to phagocytize A\u03b2 plaques, while concurrently reactivating autophagy-lysosomal function in astrocytes by increasing LAMP2 expression. Consequently, treatment with SAHA@LIPO-ANG2 in 5xFAD mice significantly reduced A\u03b2 burden, suppressed neuroinflammation, rescued synaptic loss, and ultimately reversed cognitive deficits. Our study not only elucidates a HDAC4-NHE6-pH regulatory axis in AD pathogenesis but also establishes a multifaceted nanotherapeutic strategy for restoring A\u03b2 homeostasis. Our findings may provide therapeutic strategies for treating amyloid-related diseases.",
"41950681": "ID: 41950681\nTitle: A covalent organic framework nano-chelator orchestrates multitarget clearance of Alzheimer's pathologies.\nAbstract: Metal ion dysregulation is a critical pathological driver and a promising therapeutic target in Alzheimer's disease (AD). This study presents a novel multifunctional nanoplatform based on a covalent organic framework functionalized with 8-hydroxyquinoline (COF-HQ), engineered to simultaneously address the multifaceted pathology of AD. The material not only effectively chelates Cu2+ to inhibit and reverse Cu2+-induced amyloid-\u03b2 (A\u03b2) aggregation but also, upon coordination, forms a complex with potent superoxide dismutase (SOD)-mimetic activity. This catalytic function enables the continuous scavenging of reactive oxygen species (ROS), thereby alleviating oxidative stress in the neuronal microenvironment. Furthermore, COF-HQ drives microglial polarization from the pro-inflammatory M1 to the anti-inflammatory M2 state and restores lysosomal acidification and function impaired by A\u03b2-Cu2+, thereby enhancing microglial phagocytosis and clearance of A\u03b2 to break the vicious cycle of impaired degradation. The multivalent porous architecture of the COF scaffold provides enhanced binding capacity and stability, resulting in superior anti-aggregation, antioxidant, and cytoprotective efficacy compared to its molecular building block. In vivo studies demonstrate that systemic administration of COF-HQ significantly improves cognitive performance in behavioral tests, reduces cerebral A\u03b2 plaque burden, and attenuates synaptic and neuronal loss in an AD mouse model. This work establishes a new COF-based therapeutic paradigm that concurrently targets metal dyshomeostasis, protein misfolding, oxidative stress, and defective cellular clearance, offering a comprehensive and integrated nanotherapeutic strategy for AD.",

However, therapy-induced prosurvival autophagy may attenuate therapeutic efficacy. To address this limitation, we constructed multifunctional nanoparticles (poly[lactic-co-glycolic acid]-b-poly[ethylene glycol] [PLGA-PEG2,000]-based nanoparticles coloaded with hematoporphyrin monomethyl ether and SAR405 [PHS NPs]) codelivering the sonosensitizer hematoporphyrin monomethyl ether and the selective vacuolar protein sorting 34 inhibitor SAR405. Upon low-intensity focused ultrasound irradiation, PHS NPs generated reactive oxygen species that induced mitochondrial stress while concurrently modulating autophagic flux through VPS34 inhibition. This coordinated intervention was associated with microtubule-associated protein 1A/1B-light chain 3-II and p62 coaccumulation and the presence of undegraded autolysosomal structures, suggesting impairment of lysosome-associated autophagic degradation. Enhanced oxidative stress, together with modulation of autophagic flux, was accompanied by lysosomal dysfunction and reduced degradative capacity. These alterations were associated with sustained intracellular stress and amplified oxidative injury in tumor cells. Functionally, the combined treatment suppressed tumor growth, promoted immunogenic cell death, and was accompanied by macrophage polarization toward an M1-like phenotype and increased CD8+ T cell infiltration. Validated in HPV-associated tumor models, this nanoparticle-based strategy provides a rational and potentially translatable platform to mitigate autophagy-associated adaptive responses and enhance the therapeutic potential of sonodynamic immunotherapy in solid tumors.",

In this study, we demonstrate that PS-MPs internalize into Sertoli cells, triggering CEBPB-mediated lysosomal hyperactivation and the degradation of tight junction proteins, thereby impairing the structural integrity of the blood-testis barrier (BTB). Concurrently, PS-MPs accumulate in mature human sperm, damaging mitochondrial ultrastructure and inducing ROS-driven lipid peroxidation and ferroptosis-like injury. These alterations result in reductions in motility, DNA integrity, and early embryonic development following intracytoplasmic sperm injection (ICSI). Crucially, the antioxidant N-acetylcysteine (NAC) rescued sperm functional metrics and restored embryo quality. These findings reveal dual cellular pathways, disruption of both the barrier and sperm mitochondrial integrity, by which environmental PS-MPs impair male fertility. The study highlights NAC as a promising intervention and identifies chloroquine as a potent modulator of lysosome-mediated BTB disruption. The environmental relevance of PS-MPs and their mechanistic impact on human reproductive health underscore the urgent need for strategies to reduce pre-fertilization microplastic exposure.",

Here, we develop an amphipathic polymer, YAXA, featuring acid-labile imine bonds for pH-responsive degradation and terminal NHS-activated esters for covalent conjugation of protective antigen. Through hydrophilic-hydrophobic co-assembly with the hydrophobic TLR7 agonist 3M-052, followed by antigen conjugation, YAXA forms an inhalable nanoparticle vaccine, YM3.7, in which the antigen is displayed on the hydrophilic surface while the adjuvant is encapsulated in the hydrophobic core. Following aerosolized intratracheal inoculation into the lung, YM3.7 is efficiently internalized by antigen-presenting cells and trafficked into the lysosome, where acidic conditions trigger its dissociation and co-release of antigen and adjuvant. This lysosome-targeted, spatiotemporally synchronized delivery couples antigen presentation with TLR7/NF-\u03baB activation, driving robust immune responses, including antigen-presenting cell maturation, germinal center formation, systemic and lung-resident B/T cell response, and IgG/sIgA production. In lethal pneumonia models induced by Pseudomonas aeruginosa or Staphylococcus aureus, YM3.7 markedly improves survival over a conventional antigen and adjuvant mixture. This research establishes a paradigm for developing next-generation inhalable nanoparticle vaccines, capable of spatiotemporally coordinating innate immunity, humoral immunity, mucosal immunity, and cell-mediated immunity to provide enhanced immunoprotection.",

This study aimed to investigate whether NPs exposure accelerates osteoarthritis progression in osteoarthritic mice, to elucidate the underlying molecular mechanisms, and to evaluate the therapeutic potential of quercetin. OA was induced in C57BL/6 mice via destabilization of the medial meniscus (DMM), with or without exposure to 20-nm polystyrene NPs (0.5\u00a0mg/mL in drinking water). For therapeutic intervention, quercetin (25 or 50\u00a0mg/kg) or indomethacin (3\u00a0mg/kg) was administered daily. Cartilage destruction was assessed by histology using the Osteoarthritis Research Society International (OARSI) scoring system, immunohistochemistry, and X-ray. In vitro, primary murine chondrocytes were treated with NPs and/or quercetin. Mechanisms were investigated using transmission electron microscopy, immunofluorescence, Western blot, organelle staining, and siRNA knockdown. NPs exposure significantly accelerated cartilage degradation and OA progression in DMM mice. Internalized NPs accumulated in chondrocyte lysosomes, inducing lysosomal membrane permeabilization (LMP), cathepsin B release, and subsequent NLRP3 inflammasome activation, leading to pyroptosis (evidenced by cleavage of gasdermin D N-terminal, GSDMD-N) and extracellular matrix loss. Quercetin restored lysosomal integrity, inhibited the LMP-NLRP3-pyroptosis axis in chondrocytes, and markedly attenuated NPs-aggravated cartilage destruction in vivo. This study identifies nanoplastics as novel environmental risk factors that act as pathological amplifiers in the context of osteoarthritis by inducing lysosomal destabilization-mediated pyroptosis in chondrocytes. Quercetin alleviates this pathological cascade by stabilizing lysosomes, highlighting its potential as a therapeutic agent against nanoplastics-exacerbated OA.",

It is characterized by the progressive loss of dopaminergic neurons in the substantia nigra and the accumulation of misfolded \u03b1-synuclein (\u03b1Syn) in intracellular inclusions known as Lewy bodies. Emerging evidence links \u03b1Syn accumulation to impaired lysosomal acidification and defective autophagy-lysosomal degradation, which are central to disease progression. To address this lysosomal dysfunction, we engineered a novel type of lysosome-targeted acidic nanoparticles (AcNPs) based on a biodegradable copolymer, poly(ethylene tetrafluorosuccinate-co-succinate) (PEFSU). These nanomaterials were developed to locally acidify impaired lysosomes and restore their degradative capacity. We evaluated their therapeutic potential in two familial PD models: SH-SY5Y neuroblastoma cells overexpressing A30P \u03b1Syn and A30P \u03b1Syn transgenic Drosophila melanogaster. In vitro, AcNPs effectively restored lysosomal pH, enhanced autophagic clearance of \u03b1Syn, improved mitochondrial function, and rescued A30P \u03b1Syn-induced cytotoxicity. In vivo, AcNPs treatment reduced \u03b1Syn burden, preserved dopaminergic neurons, and improved motor function in flies. This study demonstrates the first application of lysosome-acidifying polymeric nanoparticles in familial PD models and highlights the promise of rationally engineered pH-modulating nanomaterials as therapeutic agents for PD and other neurodegenerative diseases driven by lysosomal dysfunction and protein aggregation.",

The dysregulation of MiT/TFE activity has been implicated in the onset and progression of cancer and neurodegeneration, but its functions in association with pulmonary diseases remain poorly understood. In this review, we systematically summarize the findings from human pulmonary diseases and associated genetic disorders, such as asthma, cancer, Birt-Hogg-Dube (BHD) syndrome, and lung injury models that implicate MiT/TFE dysregulation in pathogenic progression. We also discussed MiT/TFE regulation and signaling through pathways involving mTORC1, AMPK, and lysosomal stress in different cellular contexts. Finally, we discussed significant mechanistic gaps, such as the absence of in vivo models targeting the combined activity of TFEB and TFE3 in disease progression and prevention. In conclusion, these insights seek to offer a comprehensive framework for understanding MiT/TFE signaling in human lung diseases and could present a promising opportunity for directing future mechanistic and translational research.",

Yet, precise spatiotemporal control of proton levels remains a formidable challenge. In this study, we introduce a near-infrared (NIR)-controlled nanoscale proton delivery system using upconversion nanoparticles (UCNPs) coated with photoacid (PA) and ferrocene (Fc). Upon 980\u00a0nm NIR stimulation, UCNPs emit UV-visible emission (300-500\u00a0nm), activating surface-bound PA to induce transient H+ release and acidify the tumor microenvironment in vivo. This acute acidic stress reduces tumor cell glucose uptake by 50% and suppresses mechanistic target of rapamycin (mTOR) signaling, triggering excessive autophagy that functionally drives mitochondrial dysfunction and intrinsic apoptosis-a process we define as proton-mediated autophagy-induced apoptosis (PAA). Fc, a biodegradable peroxidase mimic and a non-fluorescent quencher, is incorporated to enable real-time visual quantification of proton accumulation via H+-triggered biodegradation, restoring the NIR upconversion luminescence (at 800\u00a0nm) of UCNPs. Following intravenous administration, the nanoagent achieves a six-fold reduction in tumor weight and elevates proton levels in glioma, effectively triggering PAA under non-invasive NIR irradiation. This work establishes a spatiotemporally controlled platform for intratumoral proton dynamics, enabling precision cancer theranostics.",
"42093145": "ID: 42093145\nTitle: When tau stalls the lysosome: decoupling trafficking and degradation in autophagy.\nAbstract: Tauopathies are characterized by the accumulation of misfolded tau and lysosomal dysfunction, yet whether defects in the autophagy-lysosome pathway are causal or secondary remains unclear. Recent work using human iPSC-derived neurons harboring the MAPT p.R406W mutation demonstrates that pathogenic tau is sufficient to disrupt lysosomal function upstream of tau accumulation. Tau species are differentially processed within lysosomes, with phosphorylated tau retained at the lysosomal membrane, consistent with a barrier to efficient cargo processing. Importantly, pharmacologic activation of autophagy restores degradative capacity and reduces tau burden without rescuing lysosomal motility, suggesting that trafficking and degradation represent separable axes of lysosomal biology. These findings position tau as an active disruptor of proteostasis and define a degradative bottleneck that shares features with lysosomal storage disorders. Together, this work reframes autophagy dysfunction in tauopathy as a modular defect with distinct therapeutic entry points.",
"42096896": "ID: 42096896\nTitle: A mycobacterial Sec61 inhibitor disrupts lysosome function by blocking Vacuolar-ATPase biosynthesis.\nAbstract: Mycolactone is the virulence toxin of Mycobacterium ulcerans, causative agent of Buruli ulcer. Mycolactone inhibits the Sec61-dependent co-translational translocation of signal peptide-bearing secreted and membrane proteins into the endoplasmic reticulum. Sec61 inhibition leads to accumulation of mislocalised proteins in the cytosol and initially triggers an integrated stress response-dependent activation of autophagy that contributes to cell survival. Here we show sustained exposure to mycolactone blocks late-stage autophagy and induces nuclear translocation of the lysosomal stress marker TFEB. This follows loss of ATP6AP1 and ATP6AP2, Sec61-substrates required for assembly of the Vacuolar-ATPase, leading to reduced lysosomal biogenesis and acidification. These effects are reduced in cells expressing a mycolactone-resistant Sec61\u03b1 mutant and phenocopied by other Sec61 inhibitors. Loss of lysosomal function compromises the cell's capacity to withstand the proteostatic stress caused by Sec61 inhibition and could impair the ability of phagocytes to combat infection with M. ulcerans and contribute to the tissue necrosis in Buruli ulcer. Furthermore, since Sec61 inhibition is being pursued as a therapeutic target in several diseases, potential drugs should be screened against this activity to avoid unwanted side-effects.",

In the present study, we explored the effects and underlying mechanisms of SiNPs exposure during in vitro maturation (IVM) of porcine oocytes. The results showed that SiNPs significantly suppress porcine oocyte maturation as evidenced by decreased first polar body (PB1) release rate. Notably, SiNPs significantly induced abnormal expansion of cumulus cells and impaired gap junction intercellular communication (GJIC), accompanied by decreased Connexin 43 (CX43) expression and aberrant F-actin structure. Furthermore, DCFH-DA staining showed that SiNPs significantly increased reactive oxygen species (ROS) levels and malondialdehyde (MDA) content, and decreased the mRNA levels of antioxidant-related genes, including SOD1, SOD2, CAT, GPX1, PRDX2, and NRF2. JC-1 staining showed that SiNPs significantly induced mitochondrial dysfunction via diminished mitochondrial membrane potential (\u0394\u03a8m) and aberrant distribution, and decreased the mRNA levels of energy metabolism-related genes, such as NOX4 and COX2. Additionally, SiNPs significantly disrupted lysosomal function and cholesterol trafficking and decreased the mRNA levels of LDLR, NPC1, NPC2, and LAMP2, leading to reduced free cholesterol levels and the mRNA levels of estrogen synthesis-related genes, including STAR, CYP19A1, and HSD-3\u03b2.

Nano-selenium (Nano-Se) represents an advanced selenium supplement with robust antioxidant properties, which can mitigate various forms of heavy metal toxicity. However, the role of Nano-Se in alleviating Cd-induced testis damage remains unclear. Family with sequence similarity 134 member B (FAM134B) is the first identified Endoplasmic reticulophagy (ER-phagy) receptor, and the ER-phagy it mediates plays a crucial role in the reproductive system. In this study, Hy-line White roosters were randomly divided into four groups and subjected to a 90-day observation period. Serum samples and testicular tissue samples from roosters were collected for subsequent detection. Hematoxylin-eosin (H&E) staining, periodic acid-Schiff (PAS) staining, ELISA kit detection, Western blotting (WB), immunofluorescence (IF), cellular thermal shift assay (CETSA) and molecular docking techniques were employed to explore the effects of Cd on the reproductive system and the alleviating effect of Nano-Se. In vivo assays revealed that Nano-Se efficiently mitigated testicular atrophy and histological damage triggered by Cd exposure. Nano-Se reversed the Cd-mediated inhibition of steroidogenesis-related proteins, and elevated the expression of Leydig cell markers including 3\u03b2-HSD and INSL3, thereby ameliorating Cd-evoked Leydig cell dysfunction. Consistent with in vivo outcomes, in vitro tests using primary rooster Leydig cells demonstrated that Nano-Se notably restrained Cd-activated ER-phagy and excessive lysosomal acidification. Mechanistically, such protective effects were achieved by blocking TFEB nuclear translocation and preventing the downregulation of FAM134B. This present study provides a foundation for preclinical research for its usefulness as a potential therapeutic for reproductive toxicity induced by environmental heavy metal pollutants.",

Tris(2-butoxyethyl) phosphate (TBOEP) is a representative organophosphate ester that is widely detected in environmental matrices and human tissues, yet whether chronic exposure to environmentally relevant concentrations of TBOEP drives progressive neurodegenerative pathology remains unclear. Here, using Caenorhabditis elegans as a model organism, we performed a 20-day, time-resolved life-cycle exposure to environmentally relevant concentrations of TBOEP (50-5000\u202fng/L) to systematically assess chronic neurotoxicity. TBOEP exposure induced progressive, age-dependent neurodegenerative phenotypes. Early effects were characterized by selective impairment of locomotor performance starting at 50\u202fng/L, followed by broader systemic toxicity, including growth retardation, feeding deficits, and accelerated aging. Consistent with a Parkinson's disease-like trajectory, hallmark pathological features progressively worsened with exposure duration, including dopamine-dependent functional impairment, while \u03b1-synuclein aggregation and dopaminergic neuronal impairment were mainly observed at concentrations \u2265\u202f500\u202fng/L. Mechanistically, time-resolved transcriptomics identified the lysosomal pathway as a central target of TBOEP. Functional assays further confirmed that TBOEP significantly impaired lysosomal acidification. Pharmacological validation with the lysosomal chaperone ambroxol showed that improving lysosomal function mitigated TBOEP-induced neurotoxicity, supporting lysosomal dysfunction as a primary contributor to the observed pathology.

Here, we investigated the biological effects of fucoidan (FU) and fucoidan nanoaggregates (NFU) in both thyroid cancer (SW1736) and non-tumorigenic thyroid cells (Nthy-ori 3.1). NFU showed a mean diameter of ~\u2009187\u00a0nm, a low polydispersity (~\u20090.2) and a negative Zeta potential. NFU significantly reduced SW1736 cell viability, reaching\u2009~\u200960% inhibition at 0.01\u00a0mg/mL and ~\u200980% at 0.1\u00a0mg/mL after 72\u00a0h, while sparing non-tumorigenic cells. Mechanistically, NFU induced marked lysosomal enlargement selectively in tumor cells and localized predominantly within LAMP-1-positive compartments. Consistently, tumor cells showed constitutive Cathepsin D maturation and enhanced sensitivity to NFU-induced lysosomal perturbation. Collectively, these findings identify lysosomes as a primary intracellular target of fucoidan-based nanosystems and reveal a tumor-selective vulnerability to NFU-mediated lysosomal stress.

Ultraviolet (UV) exposure converted pristine nanoplastics into oxidized, irregular photoaged microplastic aggregates (> 1.2 \u03bcm). In human aortic endothelial cells, photoaged particles increased membrane stiffness and activated transcriptional programs linked to permeability, junction disruption, inflammation, and cytoskeletal remodeling. Mechanistically, photoaged particles selectively inhibited Piezo1-mediated Ca2+ signaling and downstream Notch activity without changing PIEZO1 expression, and endothelial CRISPR inhibition of PIEZO1 recapitulated these effects. In zebrafish, photoaged plastic exposure increased gut-vascular permeability and systemic spread with brain and heart accumulation, accompanied by reduced neurovascular and myocardial Ca2+ signals, depressed cardiac contractility, and abnormal locomotor behavior. Thus, photoaged plastics compromise vascular barriers through disrupted endothelial Piezo1-Notch mechanotransduction.",

While several bacterial effectors are known to subvert host immunity by modulating autophagy, whether and how the APEC Hcp2a protein influences autophagy in chicken macrophages (HD11) remains unclear. Here, we demonstrate that Hcp2a is efficiently internalized into HD11 cells and induces significant cytotoxicity. Notably, Hcp2a treatment elicited an autophagic response, as evidenced by elevated LC3-II levels and increased formation of autophagic vesicles. However, this was accompanied by p62/SQSTM1 aggregation and impaired autophagic flux, indicating a blockade in autophagosome-lysosome degradation. Quantitative proteomic analysis revealed significant down-regulation of the lysosomal pathway, particularly of key components involved in acidification and proteolysis. Functional assays confirmed that Hcp2a causes lysosomal dysfunction, characterized by the reduction in acidic lysosomal compartments and decreased levels of mature cathepsin D (CTSD). These defects ultimately impair the degradative capacity of lysosomes following autophagosome fusion, culminating in the block of autophagic flux. Our findings uncover a mechanism by which APEC Hcp2a interrupts host autophagy through lysosomal impairment, providing novel insights into APEC pathogenesis and bacterial immune evasion strategies.",

MSCs are one plausible target for these adverse effects, but the underlying cellular mechanisms of high localized nicotine exposure remain poorly understood. This study investigated how short-term nicotine and cigarette smoke extract (CSE) exposure affect human MSC function, viability, and inflammatory signaling in vitro. MSCs isolated from bone marrow were exposed to CSE containing 4-40\u00a0\u00b5M nicotine or to 100\u00a0\u00b5M-10\u00a0mM pure nicotine. CSE produced markedly stronger cytotoxicity than nicotine, reducing proliferation and rapidly inducing necrotic cell death at 20-40\u00a0\u00b5M nicotine equivalents. Pure nicotine elicited a biphasic response: concentrations below 5\u00a0mM slightly increased proliferation, while 5\u00a0mM caused apoptotic cell death with prominent lysosomal vacuolization, and 10\u00a0mM shifted cell death toward necrosis. Sublethal exposures that generated pre-apoptotic cells were associated with significant IL8 induction and MMP2 activation, whereas IL6 remained largely unchanged. Nicotine induced lysosomal disruption suggests broader impacts on MSC homeostasis beyond viability, potentially influencing lineage commitment. These findings elucidate short-term effects of nicotine and CSE; high-dose nicotine and CSE are toxic to MSCs, while the lower doses perturb the inflammatory signaling and lysosomal function. Such alterations may compromise tissue regeneration, wound healing, and periodontal stability in users of potent localized nicotine delivery products.",

Here, we demonstrate that a chimeric peptide (RS-FS), consisting of HCC-targeting RS and nanostructure-forming motifs (FS), self-assembles into nanospheres at neutral pH and transforms into nanofibers under acidic and reductive conditions. These nanofibers specifically localize to tumors and disrupt tumor cell lysosomes, thus enhancing doxorubicin's activity in human HCC cells in vitro and orthotopic HCC mice in vivo after RS-FS-doxorubicin treatment. Importantly, intravenous RS-FS potentiated oral Lenvatinib's antitumor activity up to 61-fold, and eradicated tumors in orthotopic HCC mice via HCC cell-specific lysosome disruption. Potent antitumor effects were also achieved with intravenous RS-FS and oral Epimedium brevicornu Maxim. -derived extracellular vesicles in orthotopic HCC mice, with markedly reduced tumor growth and increased cytotoxic T infiltration, in which RS-FS-mediated lysosome disruption promoted drug release and autophagic flux blockade. Our study demonstrates that RS-FS self-assembles into nanospheres or nanofibers in response to stimuli and enables tumor cell-specific lysosome disruption, resulting in enhanced drug release, autophagic flux blockade, and antitumor activities of diverse therapeutics in HCC mice, and thus provides a generalizable peptide adjuvant for sensitizing HCC-targeted therapeutics.",

Here we identify a distinct population of foamy GPNMB+ microglia/macrophages associated with lesion expansion in secondary progressive MS. Using integrated lipidomic, transcriptomic, proteomic, chemical proteomic and histological analyses of human postmortem MS lesions, we show that lesions containing foamy microglia/macrophages exhibit disrupted lipid metabolism, lysosomal stress and markers associated with heightened phagocytosis and antigen presentation without classical pro-inflammatory signatures. These lesions are enriched for oxylipins, bismonoacylglycerolphosphates and cholesterol esters, and are associated with increased B cell infiltration and IgG1. Monoacylglycerol lipase (MAGL), a lipid-metabolizing enzyme enriched in lesions with foamy microglia/macrophages, emerged as a potential therapeutic target. Inhibition of MAGL promoted lesion recovery and reduced microgliosis in a mouse model of demyelination. Finally, oxylipins in cerebrospinal fluid correlate with the proportion of foamy lesions, suggesting potential biomarkers for progression. Our findings implicate disturbed lipid metabolism in chronic MS pathology and suggest that foamy microglia/macrophages are an interesting cell type to target for progressive disease.",

Conventional viral detection techniques, although highly specific, often suffer from slow, labour-intensive workflows that limit their applicability for rapid diagnosis. Moreover, their reliability can be compromised by factors such as inadequate technical expertise and improper sample handling, potentially leading to erroneous results. When the global public health system is continuously struggling to control viral diseases like dengue, influenza, hepatitis B, and acquired immunodeficiency syndrome, cutting-edge nanotechnology and biosensor-enabled next-generation diagnostic platforms have shown improved analytical performances. Among these, aptamer-conjugated nanoparticles (ACNPs) have emerged as a promising nanosystem that integrates the high molecular recognition capability of aptamers with the unique physicochemical and optical properties of nanoparticles. Aptamers are short, single-stranded DNA, RNA, or peptide sequences that offer remarkable affinity and selectivity toward diverse viral biomarkers, including proteins, nucleic acids, and intact virions. Their conjugation with nanoparticles imparts superior stability, signal amplification, and biofunctional versatility under physiological conditions. These hybrid systems demonstrate substantial potential in biosensing, bioimaging, and providing enhanced diagnostic precision. This review aims to present the fundamental design principles of ACNP-based detection strategies and to highlight recent advances in viral diagnostics. Additionally, it underscores the underlying sensing mechanisms and analytical advantages, and discusses the current challenges associated with ACNP-enabled diagnostic platforms.",

In this study, we investigated the cytotoxic effects of NPs on intestinal and respiratory tree cells of the sea cucumber Apostichopus japonicus, focusing on oxidative stress, mitochondrial integrity, and DNA damage. Cells were exposed to 100\u202fnm NPs dispersed in culture media at concentrations of 0.1, 1.0 and 10.0\u202f\u03bcg\u202fmL-1 for 24\u202fh, with untreated cells serving as the control. Transmission electron microscopy revealed progressive cell membrane rupture, extensive vacuolation, and the presence of bilayered autophagy-like structures and monolayered lysosome-like vesicles following NP exposure. TUNEL assays revealed a significant increase in TUNEL-positive DNA fragmentation across PS-NP exposure levels, suggesting enhanced apoptosis-like cell death. A 1.0-1.4-fold increase in ROS production confirmed that NPs induced significant oxidative stress. Mitochondrial disruption was evident by increased ADP levels and reduced ATP content, oxygen consumption rate, and activities of respiratory chain complex I-V, suggesting impaired oxidative phosphorylation. Transcriptomic analysis further supported the involvement of mitochondrial pathways in NP-induced apoptosis. Moreover, after 24\u202fh of exposure, both olive tail moment (with an 8.0-11.8-fold increase) and DNA-protein crosslinking (25.7-30.2%) were markedly elevated, even at the lowest NP concentration of 0.1\u202f\u03bcg\u202fmL-1, demonstrating substantial genotoxic effects. Overall, NPs induced cytotoxicity and apoptosis in A. japonicus cells in a dose-dependent manner, with time-dependent changes in mitochondrial function. These findings highlight the sensitivity of A. japonicus cells to nanoplastic exposure and propose cellular response indicators such as ROS accumulation, ATP/ADP imbalance, and MPTP opening as potential biomarkers for ecological risk assessment in marine benthic systems.",

This study aimed to design self-nanonizing solid dispersions (SDs) using a fattigated gelatin-oleic acid conjugate (GOC) to achieve a synergistic enhancement of the solubility and permeability of TBZ. Successful conjugation of amphiphilic GOC through N-acylation was confirmed using Fourier transform-infrared and proton nuclear magnetic resonance spectroscopies. Binary GOC-based SDs prepared by spray drying could encapsulate the drug into self-assembled nanoparticles, forming approximately 130\u00a0nm above critical micellar concentration (0.887\u00a0mg/mL) and enabling enhanced drug release of 62.38\u00a0\u00b1\u00a01.14% for 120\u00a0min with minimized drug precipitation in aqueous media. Furthermore, ternary SDs incorporating fumaric acid (Fu) as a microenvironmental pH (pHm) modifier showed the highest improvement of dissolution rate and permeability, achieving a 9-fold increased release of 85.32\u00a0\u00b1\u00a02.76% within 120\u00a0min and a 2.4-fold increase in transmembrane permeability compared to pure TBZ. Reduced crystallinity and increased affinity through hydrogen-bonded molecular dispersion of TBZ into the hydrophobic oleyl cores of GOC and the formation of an amorphous drug-Fu electrostatic complex are also crucial, boosting encapsulation efficiency and dissolution rates by producing approximately 170\u00a0nm-sized nanoparticles. Collectively, the current self-nanonizing SD system resolved the solubility and permeability issues associated with TBZ to improve oral drug treatment.",

TNBC cell lines MDA-MB-231 and MDA-MB-468 were employed as in vitro models. Cell viability and clonogenic potential were assessed using CCK-8 and colony formation assays. Autophagy-related proteins (LC3-II/I, p62) and phosphorylation levels of key AKT/mTOR pathway components were analyzed by Western blotting. Autophagosome formation was visualized via transmission electron microscopy and immunofluorescence. Autophagic flux was monitored using mCherry-GFP-LC3 tandem fluorescent adenovirus. Lysosomal acidification was evaluated by LysoTracker Red and acridine orange (AO) staining. Functional rescue experiments were conducted using the AKT activator SC79. The in vivo antitumor activity of WK-13-3D was validated in a nude mouse xenograft model. WK-13-3D significantly suppressed TNBC cell viability and clonogenicity. Mechanistically, WK-13-3D concurrently inhibited AKT/mTOR signaling and directly bound to BiP, triggering endoplasmic reticulum (ER) stress. Notably, WK-13-3D treatment led to autophagic flux blockade, evidenced by autophagosome accumulation (increased LC3-II/I ratio) and impaired degradation of the autophagic substrate p62, without compromising lysosomal acidification or hydrolytic function. Activation of the AKT/mTOR pathway partially reversed WK-13-3D-induced autophagy dysregulation, whereas BiP overexpression restored autophagic flux and enhanced lysosomal activity. These dual-targeting effects converged to exert a potent and enhanced antitumor response. WK-13-3D disrupts autophagy-lysosome crosstalk in TNBC via coordinated inhibition of AKT/mTOR signaling and BiP-mediated ER stress, representing a promising lead candidate that provides mechanistic insights for TNBC treatment and warrants further preclinical investigation.",
"42188099": "ID: 42188099\nTitle: Low Shear Stress Promotes Atherosclerosis by Mediating Pathological Accumulation of Endothelial Lipid Droplets via the KLF4/TFEB/ATP1A1 Axis.\nAbstract: Atherosclerosis preferentially develops at arterial regions exposed to low shear stress (LSS), highlighting the critical role of local hemodynamic forces in disease initiation and progression. Emerging evidence indicates that endothelial lipid metabolism is a key determinant of vascular homeostasis; however, whether LSS directly regulates endothelial lipid droplets' (LDs) dynamics remains unclear. In particular, the mechano-transduction pathways linking shear stress to lysosome-mediated lipid processing within the endothelium have yet to be defined. Complementary in vitro flow systems and in vivo atheroprone models were employed to examine the effects of LSS on endothelial lipid metabolism. Endothelial LDs accumulation, lysosome-dependent lipophagy, and atherosclerotic lesion development were systematically assessed under LSS conditions. Mechanistically, molecular profiling and rapamycin-mediated functional rescue were conducted to delineate the role of the KLF4/TFEB/ATP1A1 signaling axis in LSS-induced impairment of lysosome-dependent lipophagy. We found that LSS induced pathological accumulation of LDs in vascular endothelial cells, accompanied by a marked suppression of lysosome-dependent lipophagy. Elucidation of the mechanism showed that LSS downregulated the shear-responsive transcription factor KLF4, resulting in aberrant phosphorylation of transcription factor EB (TFEB) and impaired TFEB nuclear translocation. Consequently, the TFEB transcriptional program governing lysosomal function was disrupted, including reduced expression of the TFEB target ATP1A1, leading to defective lysosomal acidification and blockade of lipid autophagic flux. Restoration of the KLF4/TFEB/ATP1A1 axis reactivated lipophagy, alleviated endothelial lipid burden, and significantly attenuated atherosclerotic lesion development. Our findings demonstrate that disruption of the KLF4/TFEB/ATP1A1 signaling pathway mediates LSS-induced impairment of endothelial lipophagy, thereby driving pathological LDs accumulation. This highlights the potential of restoring this axis as a therapeutic strategy to attenuate atherosclerotic progression.",
"42195297": "ID: 42195297\nTitle: Transcriptomic Profiling of Monozygotic Twins with Type 1 Gaucher Disease.\nAbstract: Background: Gaucher disease (GD) arises from pathogenic variants in the GBA1 gene and is known for its wide range of clinical presentations-a variability that genotype alone cannot adequately account for. Objective: This study aimed to explore transcriptomic factors that might help explain why two genetically identical twins with type 1 GD developed noticeably different clinical outcomes. Methods: We isolated peripheral blood mononuclear cells from both twins and two age-matched controls, then differentiated them into macrophages in vitro before conducting RNA sequencing. Gene expression differences were analyzed using established bioinformatics pipelines, and a subset of genes were subsequently assessed by quantitative real-time PCR (qRT-PCR) to confirm the sequencing findings. Results: Both twins shared a GD-associated transcriptional signature broadly reflecting immune activation and lysosomal stress. Interestingly, the twin who experienced systemic complications had a relative enrichment of interferon-responsive transcripts, while the less severely affected twin showed more pronounced suppression of small nucleolar RNA clusters. That said, neither difference held up after correcting for multiple comparisons, so these patterns are best viewed as exploratory trends rather than definitive findings. The qRT-PCR results lend partial support to this picture: stress- and immune-related genes (DDIT4, RPH3A, SAMSN1) trended toward higher expression in patients versus controls, and interferon-stimulated genes (ISG15, RSAD2, IFI44L) were more elevated in M2 than in M1. Conclusions: Taken together, these findings suggest that factors beyond genetics-whether epigenetic, environmental, or otherwise-may play a meaningful role in shaping how GD manifests differently even between individuals with identical DNA. Although the data are preliminary, they point to transcriptomic profiling, paired with targeted validation, as a useful starting point for building hypotheses about why this disease looks so different from one patient to the next, even when the underlying mutation is the same.",
"42197399": "ID: 42197399\nTitle: Micro/Nanoplastics and Periodontitis: An Environmental Microbiology Perspective on Oral Retention and Systemic Risk.\nAbstract: Micro- and nanoplastics (MNPs) have now been detected in human blood, placenta, and arterial tissue, yet the oral cavity has received strikingly little mechanistic attention despite serving as a primary portal of environmental exposure and a local site of polymer generation from dental and oral-care materials. This narrative review addresses that gap from an environmental microbiology perspective, synthesizing recent literature on periodontal disease, chronic low-grade inflammation, oral biofilms, dental materials, microbial-plastic interactions, and systemic chronic disease risk. Unlike prior reviews, we apply an explicit three-tier evidentiary framework (established, plausible, unproven) that distinguishes what is directly demonstrated from what is biologically plausible but unproven, and we situate the periodontal environment specifically as a particle-retention and inflammatory-amplification niche. The strongest direct oral evidence shows that human dental calculus harbors at least 26 microplastic types, dominated by polyamide (41.4%), polyethylene (32.7%), and polyurethane (7.0%). Polyethylene isolated from calculus induces cytotoxicity, apoptosis, impaired migration, NF-\u03baB activation, and upregulation of IL-1\u03b2 and IL-6 in human gingival fibroblasts. From a microbiological standpoint, oral organisms actively degrade methacrylate dental polymers, and the degradation products of these polymers reciprocally modulate oral bacterial virulence gene expression. Across experimental systems, MNPs activate oxidative stress, inflammasome signaling, macrophage polarization, and barrier dysfunction, pathways that overlap extensively with periodontal pathobiology. Adjacent environmental microbiology demonstrates that plastic-associated biofilms enhance extracellular polymeric substance production, quorum sensing, pathogen persistence, and antibiotic resistance gene transfer, supporting a plausible but not yet validated oral plastisphere within plaque and calculus. We argue that periodontitis should be reconceptualized as a chronically inflamed particle-processing interface that may increase local MNP retention, cellular reactivity, and systemic inflammatory spillover, with implications for cardiovascular, metabolic, and other chronic disease risk pathways. Current evidence does not yet prove that environmental MNP exposure causes human periodontitis, and that evidentiary boundary is maintained throughout. A priority research agenda is proposed, centered on contamination-controlled subgingival biomonitoring stratified by periodontal status, spatially resolved multi-species biofilm models, polymer source attribution, and longitudinal clinical studies linking oral plastic burden to inflammatory and systemic outcomes.",

Stress-induced senescence of plaque macrophages is associated with inflammation and instability via the senescence-associated secretory phenotype (SASP). Dysfunction of the integrated \"mitochondria-lysosome senescence axis\" is thought to play a key role in maintaining this senescent state, which correlates with lipid overload, impaired efferocytosis, and fibrous cap degradation. Multi-targ et monomers from Traditional Chinese Medicine (TCM) such as quercetin, Tanshinone IIA, berberine, and baicalein have been shown to modulate senescent macrophages, potentially via this axis. Proposed mechanisms include inhibiting p38 MAPK/p16 signaling, reducing scavenger receptor-mediated lipid uptake, enhancing cholesterol efflux, suppressing the NF-\u03baB/NLRP3 inflammasome, promoting efferocytosis via TAM receptors, and restoring metabolic support for lysosomal acidification. This review synthesizes the role of the mitochondria-lysosome axis in AS and highlights the potential of TCM monomers to stabilize plaques, providing a novel framework for therapeutic development.",

However, how food components influence MNP release from packaging materials and the resulting exposure risks remain poorly understood. Here, we investigated the effect of the primary tea polyphenol, epigallocatechin gallate (EGCG), on MNP release from polystyrene cups during a simulated tea-drinking process involving thermal treatments. A surface-enhanced Raman scattering sensor was developed to quantify released plastic particles in situ using EGCG-based luminescent metal-phenolic network labeling. The released particles were identified primarily as nanoplastics, and the presence of EGCG significantly (P < 0.05) increased MNP release, particularly during microwave heating and most prominently upon repeated cup use. Interestingly, EGCG increased the MTT response of differentiated Caco-2 cells exposed to released NPs in a dose-dependent manner, suggesting a potential mitigation of NP-associated cytotoxicity under the tested in vitro conditions. This study provides new insight into the dynamic interactions between food components and plastic packaging during realistic consumption scenarios, revealing an overlooked pathway influencing human exposure to nanoplastics. The findings expand the current understanding of contaminant release mechanisms at the food-environment interface and inform future strategies for exposure mitigation and sustainable material design to ensure food safety and protect environmental and public health.",

Small interfering RNA (siRNA) targeting the mucin MUC5AC delivered by lipid nanoparticles (LNPs) is promising but limited by low transfection efficiency. Protopanaxadiol (PPD), protopanaxatriol (PPT), and ginsenoside Rh2 (GR2) were chosen because their dammarane skeleton preserves membrane-insertion capacity for endosomal escape, whereas bulkier multi-glycosylated ginsenosides adversely affect LNP size and stability. In this study, we designed novel inhaled LNPs incorporating ginseng-derived cholesterol analogs to enhance therapeutic efficacy against asthma. PPD and PPT were used as membrane components to formulate anti-MUC5AC siRNA-loaded LNPs (designated as DLNPs and TLNPs). Flow cytometry and confocal laser scanning microscopy (CLSM) were employed to evaluate the cellular uptake and lysosomal escape of LNPs. An asthmatic mouse model was established to assess therapeutic effects of DLNPs and TLNPs through pathological section analysis and determination of inflammatory cytokine levels. The data showed that these novel formulations enhanced cellular uptake by airway epithelial cells (AECs) and promoted siRNA escape from lysosomes, thereby improving pulmonary delivery efficiency. TLNPs, in particular, demonstrated superior performance. Furthermore, DLNPs and TLNPs exerted multifaceted anti\u2011asthmatic effects in vivo, as evidenced by significant suppression of MUC5AC overexpression in AECs, attenuation of inflammatory cell infiltration, and reduction in the secretion of the critical cytokines IL\u20114 and IL\u201113.

As a major intracellular pathogen, Mtb can escape clearance by the immune system, but the underlying molecular mechanisms remain incompletely elucidated. Specific genomic regions of deletion (RD)-encoded proteins in virulent Mtb H37Rv have been implicated in modulating pathogenicity and immunity. Here, we report a novel RD15-encoding protein, Rv1977 (a mycobacterial cell wall protein with a size of 39\u2009kDa, named MEM39), which facilitates Mtb survival in macrophages. The survival of the Mtb H37Rv MEM39-deficient strain is reduced in both macrophage and murine infection models. Furthermore, the mycobacterial MEM39 protein binds fructose-diphosphate aldolase A (ALDOA), a key enzyme of glycolysis, thereby impairing ALDOA enzyme activity, disrupting macrophage metabolite flux, and reducing lactate production. The MEM39-ALDOA interaction also suppresses lysosomal acidification; reduces NLRP3 inflammasome activation and the production of proinflammatory cytokines (TNF-\u03b1, IL-6 and IL-1\u03b2); and thereby promotes bacterial survival within macrophages. Disruption of the interaction between MEM39-ALDOA and a cell-penetrating synthetic peptide (VLARYASICQ) significantly suppressed Mtb survival by restoring lactate production, lysosome acidification and proinflammatory cytokine production in both macrophage and mouse infection models. These findings revealed that mycobacterial MEM39 negatively regulates host immune defense through reprogramming ALDOA-mediated glycolysis in macrophages, thereby forming a \"mycobacterial MEM39 virulence factor-glycolysis metabolism-immunity\" regulatory axis. Targeting MEM39 or the MEM39-ALDOA interaction interface holds promise as a new therapeutic strategy against tuberculosis.",

Molecular consequences remain poorly understood. Here, we determined transcriptomic changes in S3 segments of male adult DBA wild-type (WT) and littermate diabetic Akita mice \u00b1 Sglt1 knockout (Sglt1-KO) given vehicle or SGLT2i dapagliflozin for 2 wk, and in Akita mice receiving glucagon-like peptide-1 receptor (GLP1R) agonist (GLP1RA) semaglutide. RNA sequencing was performed in S3 segments isolated by immunostaining-guided laser-capture-microdissection in deep cortex/outer medulla. Among 19,068 detected annotated genes, 838 genes were differentially expressed by SGLT2is in WT (differentially expressed genes; DEGs; P < 0.05) and 1,410 genes in Akita vs. WT. Approximately 34% of SGLT2i-sensitive genes changed in the same direction in Akita. Both maneuvers upregulated pathways of cellular proliferation (confirmed by phospho-Ser10 Histone H3 staining) and cellular response to stress, while downregulating pathways of immune/inflammatory response, cytokine production/receptor signaling, and cell adhesion/migration. Both maneuvers also induced unique responses. Unique pathway responses to SGLT2is in WT included an increase in DNA dealkylation/demethylation and lysosomal acidification, and reduced valine biosynthesis. Differences in SGLT1-dependency of responses to Akita vs. SGLT2is in WT suggested different initiating mechanisms. In Akita, SGLT2is, Sglt1-KO, and GLP1R agonism restored 12%, 18%, and 25% of DEGs, respectively; combined SGLT2i/Sglt1-KO was not synergistic. Akita downregulated whole kidney SGLT1 membrane expression, potentially to limit glucose-induced stress. GLP1RA reduced/restored cellular stress response and proliferation in Akita in S3 segments, associated with enhanced/restored kidney membrane expression of SGLT1. Finally, Akita-sensitive genes unresponsive to any of the three maneuvers were identified that may indicate new therapeutic avenues.NEW & NOTEWORTHY Both SGLT2 inhibition and diabetes increase glucose delivery to late proximal tubule S3 segments. Using transcriptomic mapping in mice, we found that both conditions induce cellular proliferation and stress responses while suppressing inflammatory pathways, but also trigger unique responses. Responses differed in their SGLT1-dependency, suggesting different initiating mechanisms. Diabetes suppressed SGLT1 expression, potentially to limit glucose-induced stress. Glucagon-like peptide-1 receptor (GLP1R) agonism reversed many diabetic transcriptomic changes in S3 segments, including stress response, associated with restored SGLT1 expression.",
"42214330": "ID: 42214330\nTitle: Mitochondria-lysosome coupling contributes to lysosome acidification and aging.\nAbstract: Nearly all cellular processes are pH dependent. The acidic pH inside the lysosome (vacuole in yeast) is essential for cellular content degradation, signaling, and autophagy. Defects in lysosome/vacuole acidification are a conserved hallmark of aging and age-related diseases. Traditionally, the lysosome/vacuole is thought to import free protons (H\u207a) from the surrounding neutral cytosol. Here, we uncovered a conserved lysosome/vacuole acidification mechanism from yeast to human involving lysosomal/vacuolar uptake of H+ pumped out by mitochondrial electron transport chain through mitochondria-lysosomes/vacuoles membrane contacts. Aging/senescence-associated disruption of mitochondria-lysosome/vacuole contacts causes lysosomal/vacuolar de-acidification, which can be reversed by either expressing an engineered linker to connect these two organelles or through an asymmetry-dependent rejuvenation process in daughter cells. Preserving lysosomal acidification in senescent human cells prevents the induction of major senescence-associated secretory phenotype factors and restores autophagic flux. These findings reshape our current understanding of the mechanisms underlying lysosomal/vacuolar (de-)acidification in both young and aged/senescent cells.",
"42217384": "ID: 42217384\nTitle: Humic acid-cation interactions reshape nanoplastic bioaccessibility and mechanistic toxic pathways toward microalgae.\nAbstract: Nanoplastics toxicity is strongly shaped by water-chemistry interactions, yet how coexisting humic acid (HA) and cation jointly restructure toxicity pathways remains poorly resolved. Herein, we systematically examined the aggregation behavior, cellular responses, and bioaccessibility of polystyrene nanoplastics (PSNPs) in Chlorella vulgaris under scenarios involving individual HA, individual cations, and their coexistence. Compared with individual cations (i.e., Na+ or Ca2+), HA-cation coexistence alleviated PSNPs-induced growth inhibition despite promoting PSNPs-algae heteroaggregation and increasing PSNPs bioaccessibility, indicating that bioaccessibility alone did not determine cytotoxicity. This was ascribed to decreased membrane damage (71.5%\u201277.5%), accompanied by reduced downstream photosynthetic impairment (17.5%\u201286.9%) and apoptosis (49.6%\u201262%). In contrast, compared with individual HA, HA-cation coexistence amplified PSNPs toxicity by enhancing particle bioaccessibility (158.7%\u2012201.9%), elevating oxidative stress (7.9%\u201247.5%), and ultimately promoting membrane destabilization (60.2%\u201269.7%). Py-GC/MS quantification confirmed that compared with individual HA, HA-cation coexistence increased PSNPs bioaccessibility from 1.14 \u00b1 0.48 to 3.36 \u00b1 0.39 \u00b5g/104 cells. Structural equation modeling further revealed that increased bioaccessibility acted as an upstream driver of toxicity only when coupled with oxidative stress and membrane damage, highlighting a conditional bioaccessibility-oxidative stress-membrane damage cascade. Together, these findings demonstrate that HA-cation coexistence induces a mechanistic shift in nanoplastic toxicity that cannot be inferred from single-factor experiments. Therefore, we highlight that realistic water-chemistry interactions involving HA and cations should be explicitly incorporated into nanoplastic risk assessment frameworks to avoid biased predictions of ecological impacts in freshwater systems.",

Herein, we engineered a ternary plasmid DNA delivery platform based on a newly synthesized sulfonyl-functionalized Gemini surfactant (NGS) via electrostatic assembly with anionic \u03b3-polyglutamic acid (\u03b3-PGA). The optimized ternary complexes NGS-pDNA-PGA (N/P/C ratio of 5:1:1), particularly those incorporating low-molecular-weight \u03b3-PGA (10\u00a0kDa), exhibited favorable transfection efficiency and biocompatibility both in vitro and in vivo. Unlike conventional binary NGS-pDNA complexes, which were restricted to caveolae-mediated endocytosis (CvME) and subsequent endoplasmic reticulum (ER) trafficking, \u03b3-PGA modification introduced a \"dual-engine\" uptake profile, with uptake-pathway inhibition studies supporting the involvement of both caveolae-mediated and clathrin-mediated endocytosis. Further investigation revealed that this multi-route internalization led to programmed intracellular routing, utilizing both ER-dependent trafficking and lysosomal escape pathways to maximize nuclear transport. Transcriptomic analysis provided potential regulating molecules in this process. This study not only presented a high transfection efficiency, biocompatible nanocarrier but also offered a proposed framework of uptake-trafficking regulation dependent routing for next-generation nucleic acid delivery. This study provided valuable insights into the mechanisms driving the enhanced efficacy of NGS nanoparticles, offering a promising platform for transporting-regulated gene delivery.",

Berbamine (BBM), a natural alkaloid with a favorable clinical safety profile, shows potential as an autophagy inhibitor, yet its precise mechanism in HCC remains unclear. Using CCK-8, colony formation, and apoptosis assays, we first demonstrated that BBM synergistically enhanced the efficacy of multiple chemotherapeutic agents (5-FU, Sorafenib, Paclitaxel) against HCC cells in vitro. This synergistic effect was confirmed in an H22 xenograft mouse model in vivo. To investigate the mechanism, we monitored autophagic flux and lysosomal function. Western blot and immunofluorescence analyses revealed that BBM treatment led to the concurrent accumulation of LC3-II and p62, indicating a blockade of late-stage autophagic flux. Further experiments, including LysoTracker staining and assessment of lysosomal protease levels, showed that BBM impaired both autophagosome-lysosome fusion and lysosomal acidification. Mechanistically, we found that BBM downregulated SIRT1 protein expression and reduced the intracellular NAD+/NADH ratio, thereby inhibiting SIRT1 deacetylase activity. This suppression impaired the nuclear translocation and function of the key autophagy transcription factor TFEB, leading to decreased levels of its downstream targets RAB7, CTSB, and CTSD. Crucially, rescue experiments using specific agonists revealed that SIRT1 activation completely reversed all BBM-induced effects, including autophagic flux blockade and downstream protein suppression, whereas TFEB activation only partially rescued the expression of RAB7, CTSB, and CTSD without restoring autophagic flux. This establishes SIRT1 as the primary upstream regulator in this pathway. Our study identifies BBM as a novel autophagy inhibitor that targets the SIRT1-TFEB axis to disrupt autolysosomal fusion and degradation, and nominates it as a promising combinational agent to overcome chemoresistance in HCC.",

Herein, we engineered a biomimetic nanoplatform (mPPE@DOX) by cloaking a poly(ethylene glycol)-block-poly(\u03b5-caprolactone) (PEG-b-PCL) core, co-loaded with doxorubicin (DOX) and vitamin E, with a membrane derived from MB49 bladder cancer cells. This design leverages homologous targeting for improved tumor accumulation and combines the chemotherapeutic action of DOX with the chemosensitizing function of vitamin E. The resulting nanoparticles demonstrated excellent colloidal stability, high drug-encapsulation efficiency, and efficient cellular internalization, leading to enhanced lysosomal escape, pronounced DNA damage, and synergistic apoptosis induction in vitro. In an orthotopic MB49 bladder cancer model, mPPE@DOX exhibited prolonged blood circulation, superior tumor-targeted delivery, and potent inhibition of tumor growth, which translated into a significant survival benefit. Importantly, this robust antitumor efficacy was achieved with markedly reduced systemic toxicity compared to free DOX. These findings highlighted a promising biomimetic strategy for precise and effective combination therapy against bladder cancer.",

Given the rapid expansion of review literature on this topic, we conducted an umbrella review integrating scientometric mapping and thematic synthesis to evaluate research trends, methodological patterns, convergent evidence, and knowledge gaps in MNPs research. Review articles indexed in the Web of Science Core Collection up to June 2025 were analyzed using combined manual refinement, automated text-mining workflows, and CiteSpace network analyses. A total of 7,349 review articles were included. The results revealed strong thematic concentration around aquatic ecosystems, fish-based models, contamination studies, and adverse biological effects, particularly involving polyethylene (PE), polystyrene (PS), polypropylene (PP), and polyethylene terephthalate (PET). There was a broad consensus on the widespread environmental occurrence of MNPs and their potential to induce oxidative stress, inflammation, cytotoxicity, and bioaccumulation. However, substantial methodological heterogeneity and structural biases were identified, including the predominance of narrative reviews, limited taxonomic diversity, and inconsistent analytical and experimental approaches. Several domains remained comparatively underexplored, especially environmental transport, degradation pathways, microorganism interactions, combined exposure scenarios, and environmentally realistic conditions. In addition, terrestrial organisms, atmospheric systems, and less frequently studied polymer types remain insufficiently represented in the current review literature. Overall, this umbrella review demonstrates that, despite the rapid consolidation of MNPs research, important limitations persist regarding evidence integration, methodological standardization, and ecological representativeness. These findings highlight the need for more integrative, standardized, and ecologically relevant approaches capable of improving ecological risk assessment and advancing the understanding of MNPs dynamics and impacts across environmental systems.",
"42226817": "ID: 42226817\nTitle: Distinct pro-inflammatory responses to pristine and microbially contaminated PET nanoplastics in a human alveolar cell co-culture.\nAbstract: The small size of nanoplastics (NPs; <1\u00a0\u00b5m in diameter) facilitates airborne transport, inhalation, and deposition in the lungs, raising significant concerns about potential effects on human health. In occupational settings, such as waste management and recycling facilities, exposure to NPs carrying microbial contaminants may pose an additional health risk to workers. In the present study, we investigated pulmonary cytotoxicity and pro-inflammatory responses after exposure to polyethylene terephthalate nanoplastics (PET-NPs) with or without microbial contaminants. PET-NPs were synthesized from a post-consumer juice bottle (PET b001) and commodity PET pellets (PET c000). The presence of microbial contaminants was assessed via receptor activation in HEK293 Toll-like receptor (TLR) reporter cells expressing TLR2 or TLR4. Co-cultures of human alveolar epithelial cells (A549) and monocyte-derived macrophages (dTHP-1) were exposed to PET-NPs (0, 10 or 100\u00a0\u03bcg/mL) that tested either negative or positive for TLR2 and TLR4 activation. After 24\u00a0h, cell viability was measured, and cytokine responses were quantified at both mRNA and protein levels. PET b001 activated TLR2 and TLR4, indicating the presence of biologically active microbial components, whereas PET c000 showed no activation. In A549/dTHP-1 co-cultures, PET b001 (10 and 100\u00a0\u03bcg/mL) significantly increased IL-1B, IL-6, IL-8, and TNF mRNA levels and IL-6 and IL-8 protein secretion. In comparison, PET c000 selectively increased IL-8 mRNA levels and protein secretion, and only at the highest tested concentration (100\u00a0\u03bcg/mL). No changes in cell viability were observed for either particle type. We found that the pro-inflammatory responses to PET-NPs are largely mediated by associated microbial components rather than the polymer itself, highlighting the importance of accounting for environmental context when evaluating their health risks. No evidence of cytotoxicity was observed, as cell viability remained unchanged. Our results further emphasize the need to assess microbial contamination prior to toxicity testing and point to potential occupational health risks in plastic waste and recycling environments.",
"42229818": "ID: 42229818\nTitle: Cigarette smoke-induced ClC-3 deficiency drives chronic bronchitis via the AKT/CREB1 axis and lysosomal-autophagic impairment.\nAbstract: Cigarette smoke (CS) exposure disrupts bronchial epithelial redox homeostasis, serving as a primary etiology of chronic bronchitis; however, the specific mechanisms linking ion transport dysregulation to CS-induced cytotoxicity remain poorly understood. This study identifies a critical protective role for the voltage-gated chloride channel ClC-3, a Cl-/H+ exchanger, in maintaining airway epithelial integrity against oxidative insult. We report significant downregulation of ClC-3 in the bronchial epithelium of chronic bronchitis patients and CS-exposed mice. Using transgenic overexpression and conditional knockout mouse models, we demonstrate that ClC-3 deficiency exacerbates, while its overexpression mitigates, CS-induced airway inflammation, systemic oxidative stress (SOD/MDA), and lung injury. Mechanistically, we show that CS exposure suppresses AKT phosphorylation, leading to the inactivation of the transcription factor CREB1. We validate that CREB1 acts as a direct transcriptional activator of CLCN3 by binding to its promoter; thus, the CS-mediated inhibition of the AKT/CREB1 axis results in transcriptional silencing of ClC-3. At the cellular level, loss of ClC-3 disrupts lysosomal acidification, resulting in a blockade of autophagic flux. This impairment prevents the effective clearance of oxidative damage, thereby promoting epithelial cell death and amplifying inflammatory responses. Collectively, these findings delineate a novel \"CS-AKT/CREB1-ClC-3-Lysosome\" axis, suggesting that restoring ClC-3-mediated lysosomal function represents a promising therapeutic strategy to restore redox balance in chronic bronchitis.",

However, their biological safety remains incompletely characterised, particularly regarding the release of micro- and nanoplastics (MNPs) during clinical use. This study evaluated the in vitro cytocompatibility of eight orthodontic aligner materials, including thermoformed systems, directly 3D-printed resins, and a polyamide-12 (PA-12) device, using MTT cell-viability assays on human dental pulp stem cells (hDPSCs). Standardised specimens were prepared according to manufacturer-recommended protocols, while MNP suspensions were generated by controlled abrasion and sonication. Cells were exposed to material eluates at concentrations of 500, 1000, and 5000 ng/100 \u00b5L for 24 to 96 hours. Cell viability and morphological analyses revealed marked material-, dose-, and time-dependent differences. Thermoformed materials and the polyamide-12 system generally exhibited more stable profiles, with viability frequently above 70% and preserved cell morphology. A subset of materials showed non-linear responses suggestive of a hormetic-like effect. By contrast, several directly 3D-printed resins showed greater reductions in viability, approaching moderate cytotoxicity at higher concentrations and longer exposure. Within the limitations of this in vitro study, thermoformed materials and polyamide-12 showed more consistent cytocompatibility than some directly printed materials. These findings highlight the need for systematic biocompatibility evaluation of orthodontic aligner materials and indicate that adherence to standardised post-curing protocols and rigorous material qualification workflows is essential to minimise potential biological risks during clear aligner therapy.",
"42251851": "ID: 42251851\nTitle: Mestranol induces a reversible lysosomal storage-like state in zebrafish microglia.\nAbstract: Environmental estrogenic compounds are increasingly recognized as neurotoxicants, yet their effects on microglia intracellular homeostasis in vivo remain poorly understood. Using zebrafish larvae as a live imaging model, we identify the synthetic estrogen mestranol as a potent inducer of a reversible lysosomal storage-like state in microglia. Mestranol exposure causes pronounced microglia hypertrophy and reduces neutral red staining, without affecting microglia number or neuronal apoptosis. Functional analyses show that mestranol-treated microglia retain phagocytic capacity toward apoptotic neurons and bacterial particles but fail to efficiently digest internalized cargo, leading to intracellular accumulation. Although acidic vesicles and protease\u2011associated compartments expand and disperse throughout the cytoplasm, lysosomal degradative efficiency is markedly impaired, suggesting that cargo digestion is compromised despite the formation of acidic phagolysosomal compartments. Transcriptomic profiling of flow\u2011sorted macrophage/microglia populations reveals coordinated down\u2011regulation of lysosomal-phagosomal and immune gene networks, including MIT/TFE family transcription factors (TFEB/TFEC) and immune master regulators such as SPI1, IRFs, BATF, MAFB, and RUNX3. Overexpression of TFEC partially rescues both estradiol and mestranol-induced microglia hypertrophy and neutral red loss, although the rescue is only partial, indicating a more complex mechanism involving additional TFEC-independent pathways. Notably, microglia lysosomal dysfunction and hypertrophy are reversible upon drug withdrawal. Together, our findings demonstrate that mestranol induces an acquired and regulatable lysosomal stress state in microglia, characterized by immune transcriptional suppression and impaired intracellular digestion. This work establishes a live, reversible in vivo model for studying estrogen\u2011associated neuroimmunotoxicity and microglia vulnerability to lysosomal stress.",
"42251935": "ID: 42251935\nTitle: Innovative mucosal nanocarrier systems for enhanced immune response against respiratory pathogens.\nAbstract: Effective pulmonary vaccination remains limited by the pulmonary surfactant (PS) barrier and inefficient intracellular delivery of vaccine cargo to alveolar antigen-presenting cells, particularly alveolar macrophages. Inspired by the natural compatibility of alveolar macrophage-derived vesicles with the alveolar environment, we developed biomimetic alveolar macrophage membrane vesicles (AMVs) as a mucosal nanocarrier platform. This study aimed to develop a nanovaccine platform that addresses key extracellular and intracellular barriers in the lung and to evaluate its immunogenicity and protective efficacy in multiple respiratory pathogen models. AMVs were engineered to improve performance in the PS environment and to achieve preferential uptake by alveolar macrophages. An Antigen Capture and Cytosolic Delivery System (ACCDS) was incorporated, comprising: (1) an engineered surfactant protein A domain for broad pathogen binding; (2) a pH-responsive listeriolysin O module designed to facilitate endo/lysosomal escape and enhance cytosolic access of cargo; and (3) encapsulated Poly(I:C) to activate TLR3 and support RIG-I/MDA5-associated signaling. AMV-ACCDS-Poly(I:C) showed improved delivery performance in the PS-associated environment and preferential uptake by alveolar macrophages compared with synthetic nanoparticles and a commercial transfection reagent. Dual innate activation was associated with stronger IFN-\u03b2 and IL-18 responses than those induced by the tested control formulations. The platform promoted the local establishment and/or differentiation of lung-resident memory-like CD8+ T cells and was accompanied by IL-18-associated metabolic remodeling. In prime-boost studies, it conferred complete protection in lethal influenza and pseudorabies virus challenge models and reduced pulmonary burden in a Mycoplasma infection model. AMV-ACCDS-Poly(I:C) provides a biomimetic strategy to address key barriers in pulmonary vaccination and supports the potential of membrane-based mucosal vaccine systems for protection against respiratory pathogens.",
"42253471": "ID: 42253471\nTitle: Polyethylene terephthalate and polypropylene nanoplastics toxicity in vitro: Comparative analysis of paraquat adsorption and cytotoxicity.\nAbstract: According to global statistics, approximately 400\u00a0million tons of plastic are produced worldwide each year, yet only about 9% is recycled. Environmental degradation of plastics generates microplastics and nanoplastics, which have been shown to induce oxidative stress, genotoxicity, and endocrine disruption. Additionally, nanoplastics can adsorb environmental pollutants, act as transport vectors within biological systems, and alter pollutant toxicokinetics. In this study, we conducted a comparative analysis of paraquat adsorption and in vitro cytotoxicity of polyethylene terephthalate nanoplastics (n-PET) and polypropylene nanoplastics (n-PP). The results showed that n-PET exhibited significantly higher adsorption capacity for paraquat than n-PP, with maximum interaction observed at pH 11 and particle sizes below 100\u00a0nm. In vitro experiments using the human embryonic kidney (HEK-293) cell line demonstrated higher cytotoxicity for n-PET compared to n-PP. Co-exposure to n-PET and paraquat resulted in significantly greater cytotoxic effects than exposure to either agent alone. IC\u2085\u2080 values were determined at 24, 48, and 72\u00a0h. Furthermore, both nanoplastics disrupted cellular redox homeostasis, with n-PET inducing a more pronounced oxidative imbalance than n-PP. These findings indicate that n-PET may act as a stronger carrier of paraquat and pose a greater toxicological risk under co-exposure scenarios, highlighting the importance of nanoplastic-pollutant interactions in environmental risk assessment.",
"42264605": "ID: 42264605\nTitle: Micro- and nanoplastics as vectors of aquatic pollutants and genotoxicity: An integrated review across aquatic and mammalian systems with special reference to the scenario in India.\nAbstract: Microplastics (MPs) and nanoplastics (NPs) are environmental pollutants with paramount implications for aquatic ecosystems and, through that route, human health, particularly due to their oxidative stress-mediated genotoxic potential. This review is a synthesis of findings from recent studies, with emphasis on the scenario in India, on the bioavailability, toxicological risks, and cellular mechanisms of MPs and NPs (MNPs) in various organisms, separately addressing evidence from aquatic models, including marine mussels, common carp, zebrafish, rotifers, etc., and mammalian systems relying essentially on in vitro studies. Key evidence indicates that MPs adsorb persistent organic pollutants like Polycyclic Aromatic Hydrocarbons (PAHs), enhancing their bioavailability and inducing oxidative stress, immunological alterations, and developmental toxicity, which are closely associated with DNA damage and chromosome instability. As regards aquatic organisms, combined exposure to MPs and heavy metals to fish models exacerbates biochemical disruptions and immune suppression, along with oxidative stress-linked genotoxic responses such as DNA strand breaks and micronucleus formation. Zebrafish embryos exhibit microcirculation dysfunction and pathological angiogenesis upon NP exposure. Mammalian cell studies reveal size-dependent cytotoxicity, with smaller NPs causing greater oxidative damage and membrane disruption, which triggers mitochondrial dysfunction, excessive ROS production, cell-cycle arrest, and activation of DNA damage response pathways, evidenced by micronucleus formation, chromosomal abnormalities, and oxidative DNA lesions. Overall, toxicity is influenced by particle size, charge and co-contaminants, with oxidative stress emerging as the central mechanism that connects cellular toxicity to genetic damage. This review underscores the urgent need for integrated, multidisciplinary approaches to assess the environmental and toxicological risks of MNPs with special emphasis on standardized genotoxicity assessment, while informing regulatory and mitigation strategies for the future.",
"42265723": "ID: 42265723\nTitle: Surface-driven endocrine activity of nanoplastics: polymer- and size-dependent estrogen and androgen receptors modulation without steroidogenesis perturbation.\nAbstract: Growing production and use of plastics have led to significant environmental pollution including the formation and accumulation of plastic nanoparticles (PNPs). Due to their small size, PNPs easily enter the human food chain; however, humans are also exposed to plastics through other consumer pathways, such as the use of cosmetic products. Despite considerable efforts to investigate the potential adverse effects of plastics, their impact on human health is not yet fully understood. In particular, endocrine disruption has emerged as a potential mechanism underlying reported reproductive and hormonal effects of micro- and nanoplastics. We applied an OECD-aligned in vitro test guidelines (TGs) to a factorial panel of eight PNPs spanning four common polymers (polystyrene (PS), polyethylene (PE), polypropylene (PP), polyethylene terephthalate (PET)) with size-resolved materials and polymer-matched mixtures. Thus, estrogen receptor a (ER\u03b1) transactivation (TG 455), androgen receptor (AR) transactivation (TG 458, antagonist mode), and H295R steroidogenesis (TG 456) assays were performed using HeLa-9903, AR-EcoScreen GR KO M1, and NCI-H295R cell models, respectively. Across 0.1-10\u00a0mg L\u207b\u00b9, no cytotoxicity was observed. PENPs (350\u00a0nm) and PPNPs (180\u00a0nm) acted as ER agonists, whereas PPNPs (50 and 180\u00a0nm) and PENPs (350\u00a0nm) antagonized AR; PSNPs and PETNPs showed no activity when tested individually. Notably, several mixtures elicited ER and AR responses even when constituent singles were inactive, indicating mixture-dependent potentiation. In contrast, the H295R assay did not meet the OECD decision rule for altered steroidogenesis: sporadic shifts in pathway intermediates did not propagate to estradiol or testosterone. Altogether, the data support a surface- and polymer-dependent, receptor-proximal mode of action for PNPs and highlight mixture effects as a critical, underappreciated driver. These results move endocrine hazard evaluation beyond polystyrene surrogates and provide decision-useful guidance on which polymers/sizes and mixture contexts merit priority in exposure monitoring and risk assessment.",

New Approach Methodologies (NAMs) offer valuable tools to improve the mechanistic understanding of nanoscale processes and support hazard identification without animal testing. This study investigated the biological effects of exposure to 0-100 \u00b5g/mL 100 and 20 nm polystyrene (PS-NPs) and 100 nm polycaprolactone nanoplastics (PCL-NPs) using advanced in vitro intestinal models and the 3R-compliant in vivo Caenorhabditis elegans model. In vitro endpoints included cytotoxicity, oxidative stress, DNA damage, cellular internalization, and barrier integrity, while in vivo analyses focused on oxidative stress and locomotor behavior across multiple exposed generations. PS-NPs induced significant DNA damage in vitro, particularly at \u226550 \u00b5g/mL after 24-48 h exposure, and were rapidly internalized by cells, with 20 nm particles also detected in the nucleus. In contrast, 100 nm PCL-NPs elicited weaker biological responses. In vivo, PS-NPs caused an increase in oxidative stress response and locomotor behavior across exposed generations, whereas PCL-NPs produced milder effects, consistent with in vitro findings. These results support the potential of integrated NAMs for assessing human health risks associated with MNP exposure within a One Health framework.",
"42274750": "ID: 42274750\nTitle: From lipid overload to autophagy collapse: how lipid dysregulation drives chronic inflammation and metabolic disease.\nAbstract: Autophagy is a central homeostatic mechanism that preserves intracellular quality control by clearing damaged organelles, aggregated proteins, and excess lipids. Increasing evidence indicates that the lipid-autophagy axis is a critical determinant of chronic inflammatory and metabolic disease. Cholesterol-rich and oxidatively modified lipoproteins, including very-low-density lipoprotein (VLDL), low-density lipoprotein (LDL), oxidized LDL, and lipoprotein(a), can impose lysosomal stress, disturb autophagosome maturation, and amplify oxidative and inflammatory signaling, whereas high-density lipoprotein-mediated cholesterol efflux supports cellular lipid clearance and autophagic competence. When chronic lipid overload exceeds lysosomal and autophagic capacity, cells transition from adaptive lipophagy to impaired autophagic flux, leading to lipid-droplet accumulation, mitochondrial dysfunction, inflammasome activation, and sustained cytokine production. This review synthesizes mechanistic insights linking lipid dysregulation and autophagy failure across atherosclerosis, metabolic dysfunction-associated steatotic liver disease/metabolic dysfunction-associated steatohepatitis (MASLD/MASH), and neurocognitive disorders. We further discuss how defective autophagy impairs efferocytosis, phagosome maturation, and inflammasome restraint, thereby contributing to unresolved inflammation and inflammatory cell-death signaling. Translationally, we outline therapeutic strategies that combine metabolic unloading, lipid-lowering interventions, autophagy-lysosome modulation, and flux-based biomarker approaches. Lipid-induced autophagic flux failure provides a unifying framework for understanding how metabolic stress evolves into chronic inflammation and organ dysfunction and identifies actionable targets for precision therapeutic intervention.",
"42284733": "ID: 42284733\nTitle: VPS13C-mediated endoplasmic reticulum-lysosome tethering in neuronal stress responses.\nAbstract: Organelle contact sites are increasingly recognized as regulatory interfaces that coordinate lipid transfer, ion signaling, and metabolic adaptation. In neurons, communication among the endoplasmic reticulum (ER), lysosomes, and mitochondria is essential for cellular homeostasis. Recent studies have identified vacuolar protein sorting 13 homolog C (VPS13C), a lipid transport protein, as a key mediator of ER-lysosome tethering and as an important component of the response to lysosomal stress. Structural analyses show that VPS13 family proteins form elongated lipid transport channels that are proposed to facilitate phospholipid transfer between adjacent membranes. Following lysosomal damage, VPS13C is recruited to ER-lysosome contact interfaces, where it forms tethering bridges that may support membrane repair by enabling high-capacity lipid transfer from the ER to lysosomal membranes. Beyond membrane repair, these contact interfaces may also participate in broader organelle communication networks. ER-lysosome contacts can occur in proximity to ER-mitochondria junctions, potentially forming multi organelle signaling hubs that coordinate lipid redistribution, calcium signaling, and mitochondrial adaptation. These signals may influence downstream responses, including activation of TFEB and TFE3, which regulate lysosomal biogenesis and autophagy. Disruption of this contact site network has emerged as a potential contributor to Parkinson's disease. Loss of VPS13C function is associated with altered lysosomal homeostasis and intersects with pathogenic pathways involving \u03b1-synuclein aggregation, PINK1/Parkin-mediated mitophagy, and LRRK2 signaling. This review presents a framework in which ER-lysosome tethering is considered part of a staged cellular damage response linking membrane repair, metabolic coordination, and transcriptional adaptation.",
"42287918": "ID: 42287918\nTitle: Food allergen binding to pristine PET nanoplastic and their effect on allergic immune responses in vitro.\nAbstract: Plastic pollution is steadily increasing and has been linked to several diseases. At the same time, there has been an increase in allergic diseases over the past decades, with evidence suggesting a connection to environmental pollution. Since human exposure to plastic pollution is inevitable, the effects of nanoplastics (NPs) on allergic responses need to be elucidated. Therefore, we investigated the binding of food allergens to various pristine polyethylene terephthalate (PET) NPs, and their effect on allergic responses in vitro. We found that nanosized PET (nPET) NPs did not induce acute or long-term cytotoxicity in peripheral blood mononuclear cells and Caco-2 cells, nor did they cause epithelial barrier disruption using 5\u202f\u00b5g\u202fmL-1. Furthermore, allergen transport over Caco-2 monolayers was not affected by long-term exposure to nPET. Importantly, food allergens (bovine \u03b2-lactoglobulin, shrimp tropomyosin and bovine lactoferrin) were bound with different affinity to PET NPs (Kd 4.6-107.1\u202fnM). This was reflected in the ability of the allergens to influence aggregation behavior, as well as in the varying amounts of allergen bound in the hard corona. When presented to monocyte derived dendritic cells, allergens in the nPET corona were taken up to a higher extent than allergens alone. However, no changes in activation of co-stimulatory markers were found. Finally, the allergenic activity of allergens in the nPET corona was preserved compared to allergen alone, assessed by a mediator release assay and basophil activation test. In conclusion, we found that PET NPs can carry allergens that are internalized to a higher extent by monocyte-derived dendritic cells than non-bound allergens and can activate effector cells ex vivo, which may affect the immune response in allergic individuals.",

Evidence of negative effects of nanoplastics is heterogeneous and provides limited insights into the underlying pathogenic toxicity mechanisms in humans. In the present study, carboxylate-modified fluorescently labelled polystyrene nanoparticles (PS NPs) were used to investigate uptake and cytotoxicity in three different hepatic models of varying complexity, including HepG2 cells, IHH cells, and human precision-cut liver slices (hPCLS). The results show model- and dose-dependent effects on hepatocytes. 74.2%\u2009\u00b1\u200913.4% of the IHH cells showed PS NPs uptake at 0.1\u2009\u03bcg/mL, which is considerably lower than the estimated plastic concentration in human blood (1.8-4.7\u2009\u03bcg/mL). The viability of IHH cells decreased to 10.6%\u2009\u00b1\u20099.1% after exposure to 100\u2009\u03bcg/mL for 48\u2009h. Early signs of hepatic injury were found in hPCLS at high concentrations. No changes were observed in the redox state and mitochondrial respiratory parameters of HepG2 cells after exposure. The PS NPs exposure experiments show uptake across all three hepatic models and toxic effects in IHH cells and hPCLS. Overall, the study highlights the need for physiologically relevant human tissue models to understand the impact of nanoplastic pollution on human health. Particles of plastic described as microplastics (MP) and nanoplastics (NP) are accumulating in the environment from a range of sources, including the fragmentation of large plastic items during use and after disposal. NPs are invisible to the naked eye and can enter the human body by consuming food and drinks and breathing air containing these particles. Once inside the body, NPs can reach and accumulate in the organs and body tissues. This study used three models of the liver to test what happens after exposure to polystyrene NPs. It shows that polystyrene NPs can accumulate in the liver cells even at low exposure levels and can also cause damage and death of liver cells at higher levels. The study adds to the scientific evidence of harmful effects of NPs on human health, the environment, and economies and pushes for policies towards a sustainable future.",

However, early hepatocyte responses associated with nanoplastics exposure remain poorly understood. Here, we combined high-throughput Cell Painting-based phenomics, untargeted metabolomics, and Seahorse mitochondrial functional assay to investigate the effects of 100\u00a0nm polystyrene nanoplastics on human HepaRG hepatocytes, a surrogate for primary human hepatocytes. At the tested concentrations (6.25-100\u00a0\u00b5g/mL), exposure did not induce overt cytotoxicity, enabling assessment of early sublethal cellular responses. Phenomics revealed widespread subcellular perturbations, with 16.4% of the measured phenotypic features significantly altered. Mitochondria-associated features represented the dominant altered phenotypic signature, showing pronounced changes in granularity, texture, and radial distribution, alongside alterations in endoplasmic reticulum- and cytoskeleton-associated features. Untargeted metabolomics of intracellular metabolites and the extracellular secretome revealed metabolic alterations, characterized by changes consistent with altered \u03b2-oxidation, lipid handling, membrane stress, and central carbon metabolism, including changes in the tricarboxylic acid (TCA) cycle and amino acid catabolism. Pathway analysis identified the TCA cycle as one of the most significantly affected pathways (FDR\u00a0=\u00a00.028). Integrated phenomic-metabolomic analysis revealed strong correlations between mitochondrial phenotypic features and metabolites involved in lipid and energy metabolism, indicating a coordinated structural-metabolic response to polystyrene nanoplastics exposure. Functional assessment using Seahorse assay showed reduced basal and maximal respiration and decreased ATP-linked O2 consumption. Together, these findings provide evidence that 100\u00a0nm polystyrene nanoplastics elicit early mitochondria-associated phenotypic, metabolic, and functional responses prior to overt cytotoxicity under the tested conditions. They also highlight the value of phenomic-metabolomic-functional integration for profiling sublethal nanotoxicological responses and guiding future targeted mechanistic studies.",
"42305091": "ID: 42305091\nTitle: Vacuolar H+-ATPase Preserves Cardiolipin Homeostasis Through the Lysosomal-Mitochondrial Axis to Restrain Cardiac Aging.\nAbstract: Cardiac aging involves progressive mitochondrial dysfunction, contributing to heart failure. Cardiolipin (CL), essential for mitochondrial function, is increasingly depleted in aging cardiomyocytes, promoting mitochondrial decline. Lysosomal degradation relies on v-ATPase (vacuolar-type H+-ATPase)-mediated acidification, and although lysosomes regulate phospholipid metabolism, their roles in CL homeostasis during aging remains unclear. This study examines whether v-ATPase dysfunction drives age-related cardiac changes by disrupting CL metabolism and mitochondrial function. To investigate underlying mechanisms and causality, we use RNA sequencing, targeted lipidomics, immunofluorescence microscopy, (co)immunoprecipitation, proximity ligation assays, subcellular fractionation, mitochondrial respiration analysis and echocardiography, a cardiolipin synthase-1 (Crsl1) knockout mouse model, and 2 v-ATPase knockout models. In addition, we assess whether a nutraceutical intervention targeting v-ATPase dysfunction can mitigate heart failure in aging mouse models and elderly people. Our present findings reveal a sequence of events driving age-related cardiomyopathy: declining cardiac nicotinamide adenine dinucleotide levels impair v-ATPase-mediated lysosomal acidification by weakening the interaction between nicotinamide adenine dinucleotide-dependent glycolytic enzyme aldolase and v-ATPase. This disruption increases lysosomal membrane permeability by reducing lysosomal acidification, allowing cathepsin B to leak into mitochondria. There, cathepsin B disrupts mitochondrial CRLS1 (cardiolipin synthase I), impairing CL synthesis and remodeling. The resulting CL deficiency causes mitochondrial oxidative stress and programmed cell death, leading to mitochondrial and cardiac dysfunction. Genetic or chemical inhibition of v-ATPase and of CRLS1 in mouse models reproduce these age-related defects, highlighting their central roles in cardiac aging. Restoring nicotinamide adenine dinucleotide levels rescues lysosomal acidification and CL metabolism, protecting against age-related cardiomyopathy in rodents and humans. Augmenting v-ATPase-mediated lysosomal acidification offers novel therapeutic strategies to combat age-related cardiomyopathy by rewiring CL homeostasis.",

Although inhaled NPs rapidly acquire a protein corona that shapes their bioactivity, the consequences of this process in cancer-susceptible lungs remain unclear. Here, we investigated whether NPs form a disease-specific pathogenic protein corona in lung adenocarcinoma that rewires immune signaling and accelerates tumor progression. Polyethylene terephthalate (PET) NPs were generated by mechanical fragmentation and extensively characterized. In tumor-bearing mice, inhaled PET NPs accelerated tumor growth relative to controls. Proteomic analysis of PET NPs incubated with bronchoalveolar lavage fluid from patients with lung adenocarcinoma identified lysozyme (LYZ) as a selectively enriched corona component associated with tumor stage and metastasis. Corona formation induced conformational remodeling of LYZ, enhanced its enzymatic activity, and prolonged its membrane retention. Mechanistically, corona-bound LYZ engaged Toll-like receptor 4 and activated a PGRN-LXR\u03b1 signaling axis, thereby increasing lysosomal acidification-dependent efferocytosis, promoting M2 macrophage polarization, and reducing CD8+ T-cell infiltration. In vivo, AAV9-mediated knockdown of LYZ or PGRN attenuated PET NP-induced efferocytosis, reversed immunosuppressive reprogramming, restored CD8+ T-cell infiltration, and suppressed tumor growth, demonstrating the functional requirement for this corona pathway. These findings establish disease-derived PET NP coronas as active nano-bio interfaces that connect environmental PET NP exposure with efferocytosis-driven immune evasion in lung adenocarcinoma. This work provides a mechanistic link between airborne NPs and tumor progression in susceptible hosts and highlights corona-mediated signaling as a potential therapeutic target and environmental health concern.",

However, mechanistic insight is limited by the lack of human-relevant, scalable test systems for developmental neurotoxicity (DNT). Here, we establish and apply a peripheral blood-derived human neural progenitor cell (NPC) platform as a reproducible in vitro model to evaluate MNP-induced DNT under low-dose conditions reflecting currently available estimates of human exposure. Using this system, we systematically investigated the effects of 2\u202f\u00b5m, 100\u202fnm, and 20\u202fnm polystyrene particles and polyester microfibers over a 21-day neuronal differentiation paradigm. The model enables simultaneous assessment of key DNT endpoints, including neuronal differentiation, neurite outgrowth, cell cycle progression, and oxidative stress. MNP exposure impaired neuronal maturation in a size- and shape-dependent manner, reducing neurite outgrowth and \u03b2III-tubulin (TUJ1) expression. Nanoscale particles were efficiently internalized and localized to endo-lysosomal compartments, whereas micron-sized particles remained primarily surface-associated. Mechanistically, MNP exposure induced mitochondrial oxidative stress, decreased superoxide dismutase 2 expression, and disrupted cell cycle exit, resulting in sustained progenitor proliferation. Importantly, pharmacological scavenging of reactive oxygen species with N-acetyl-L-cysteine rescued differentiation deficits and normalized cell cycle dynamics, demonstrating a causal role for redox imbalance. Together, these findings validate peripheral blood-derived human NPCs as a sensitive and scalable platform for DNT assessment and provide mechanistic evidence that MNPs impair early human neurodevelopment through size-dependent uptake and oxidative stress pathways.",

The pathophysiological consequences of GBA1 mutations on dopaminergic neuronal function, especially their impact on lysosomal function, mitophagy, and mitochondrial bioenergetics, remain unclear. Fibroblasts and dopaminergic neurons generated from induced pluripotent stem cells (iPSCs) derived from patients with\u00a0GBA1-PD were used in the study. Live-cell imaging was performed to measure lysosomal acidification, protease activity, mitochondrial membrane potential, and mitophagy. Mitochondrial morphology and autophagic vesicles were examined using transmission electron microscopy. Oxygen consumption rate was measured by Seahorse assay. V-ATPase assembly was quantified using fluorescence lifetime imaging with F\u00f6rster resonance energy transfer (FLIM-FRET), and pharmacological interventions included rapamycin and acidic nanoparticles. GCase activity, lysosomal acidification, protease activity, mitophagy and mitochondrial bioenergetic function were all impaired in GBA1 mutant dopaminergic neurons. Mitochondria were fragmented, with reduced membrane potential and oxygen consumption. Mechanistic target of rapamycin complex 1 (MTORC1) was constitutively phosphorylated and FLIM-FRET measurements confirmed impairment of lysosomal V-ATPase assembly, which was reversed by rapamycin treatment. Rapamycin and lysosome-targeting acidic nanoparticles rescued lysosomal pH and restored mitophagy, mitochondrial membrane potential and mitochondrial oxidative phosphorylation complex level in the GBA1 mutant dopaminergic neurons. We revealed a novel mechanistic link between GBA1 mutations and mitochondrial dysfunction, as the disruption of V-ATPase assembly driven by MTORC1 activation impairs lysosomal acidification. This causes impairment of mitophagy, leading to mitochondrial dysfunction, undermining dopaminergic cell function and fate. Pharmacological intervention with rapamycin or acidic nanoparticles restores lysosomal pH and rescue mitochondrial function, representing a novel therapeutic approach for\u00a0GBA1-PD .",

Immune-subversive bacteria in the periodontitis microenvironment, such as Porphyromonas gingivalis, can evade conventional therapies by invading cells and inducing lysosomal dysfunction. Here we develop an injectable supramolecular hydrogel through the co-assembly of recombinant human type I collagen (COL), poly-\u03b5-lysine (PL), and puerarin (PUE). Supramolecular amorphization improves PUE's solubility and permeability, enabling a dual-compartment antibacterial strategy via effective trans-barrier delivery. Extracellularly, PL and PUE synergistically disrupt bacterial membranes and metabolism, while concurrently mitigating bacterial toxin induced pro-inflammatory macrophage polarization. Intracellularly, the supramolecular complexes facilitate PUE accumulation in phagolysosomes. By counteracting local oxidative stress, the internalized PUE restores lysosomal acidification and alleviates bacteria-induced immuno-metabolic dysregulation. In vivo, the hydrogel manipulates the local inflammatory microenvironment and facilitates periodontal tissue repair. This study provides a clinically translatable supramolecular strategy for treating intracellular infections and restoring tissue homeostasis.",
"42339737": "ID: 42339737\nTitle: Ex vivo pretreatment of donor organ with siRNA nanoparticles attenuates cold ischemia-reperfusion injury in cardiac transplantation.\nAbstract: Heart transplantation is an optimal therapeutic regimen for terminal-stage cardiac failure. However, cold ischemia-reperfusion injury (CIRI) remains an unavoidable and outstanding challenge, which is a significant obstacle to early graft dysfunction and long-term survival. Blockage of complement, apoptosis, and inflammation by small interfering RNA is considered a strategy for attenuating CIRI and protecting cardiac function. However, their delivery to the donor organ is still a serious challenge due to the polyanionic nature and high molecular weight properties. Here, we have designed a novel functionalized gene delivery system of direct delivery and sustained release of siRNAs targeting complement C3 (C3), Caspase-3, and nuclear factor \u03baB (NF-\u03baB) to treat the donor organ prior to transplantation. The functionalized gene delivery system (siRNA-TNPs), composed of CaCO3/CaP/TAT embellished carboxymethyl chitosan (CaCO3/CaP/TCMC) and synthesized through the co-precipitation method, efficiently encapsulates siRNAs during self-assembly. The siRNA-TNPs safeguards siRNAs from biological degradation, facilitates intracellular siRNA transfection, promotes lysosomal escape, and enhances the delivery efficiency of siRNA to the donor hearts. Perfusion of donor hearts with siRNA-TNPs prior to transplantation attenuated C3, Caspase-3, and NF-\u03baB genes expression of donor heart for at least 5\u00a0days after transplantation. Furthermore, silencing of C3, Caspase-3, and NF-\u03baB genes expression alleviated cell apoptosis, myocardial damage, tissue inflammation, and rejection and improved cardiac function. These data suggest that the multiple-target siRNA-TNPs solution can extend the preservation time for donor grafts, attenuate IRI, and protect cardiac function in murine models of heart transplantation, which provides a principal of concept for potential clinical translation.",

A diverse array of therapeutic entities, including peptides, single-chain variable fragments (scFvs), and small molecules, have demonstrated the ability to interact with A\u03b2 oligomers, thereby suppressing their aggregation and associated neurotoxicity. Despite these advances, such agents frequently struggle to promote the phagocytosis and subsequent breakdown of aggregated A\u03b2 by microglia. Moreover, the dense accumulation of A\u03b2 oligomers may resist enzymatic hydrolysis within the acidic lysosomal lumen, contributing to lysosomal stress and dysfunction. To overcome these problems, we engineered a multifunctional fusion protein, p62-LIR-W20-Tuftsin (W20-LT), consisting of an oligomer-specific scFv, a microglia-targeting Tuftsin peptide, and a p62-LIR peptide to activate autophagy. In vitro assays demonstrated that W20-LT significantly outperformed the parental W20 by promoting the rapid microglial uptake of A\u03b2 oligomers and enhancing their intracellular clearance through an autophagy-associated pathway. In APPswe/PS1dE9 (APP/PS1) mice, a low-dose regimen (0.5\u00a0\u00b5g, every 3 days) of W20-LT, but not W20, significantly ameliorated cognitive deficits and reduced amyloid pathology. Mechanistically, W20-LT was associated with enhanced autophagy-lysosomal pathway activity, as indicated by increased LC3B-II and reduced p62 levels, together with downregulated CatD and LAMP1 levels, thereby mitigating neuroinflammation. In summary, our findings suggest that W20-LT represents a promising proof-of-concept therapeutic strategy that combines scFv-based A\u03b2 oligomer recognition with enhanced autophagy-associated clearance, thereby mitigating AD pathology.",
"42341416": "ID: 42341416\nTitle: Rapid screening approaches to identify and confirm lysosomotropic agents among ECCS class 2 basic drugs.\nAbstract: Lysosomes are acidic organelles that function as the digestive system of the cell. Weak basic small molecule compounds can diffuse into lysosomes and become protonated and trapped in a phenomenon known as lysosomal sequestration or trapping. Lysosomal trapping can influence unbound drug concentrations at the site of action, and consequently, drug responses. Drug accumulation in lysosomes may also impair phospholipid metabolism, leading to a severe side effect called drug-induced phospholipidosis. Current methods used to evaluate lysosomotropism are either indirect (high-throughput, but low sensitivity) or direct (sensitive but time- and labor-intensive). Moreover, no validated in-silico lysosomotropism prediction tools are publicly available. In this study, we developed a rapid fluorescence-based platform to screen for lysosomotropism and quantify lysosomal trapping propensity (IC50) of compounds in a standardized way. We also apply this method to various compound libraries including BBB (Blood-Brain Barrier) and protein degrader/PROTAC (Proteolysis-Targeting Chimera) compounds. This platform confirmed basic ECCS (Extended Clearance Classification System) class 2 compounds as lysosomotropic, and other ECCS class compounds as non-lysosomotropic. Collectively, this study provides measurable and efficient tools (in-silico & in-vitro) to identify and measure lysosomotropism, which can be applied by preclinical programs to decipher causes of intracellular accumulation.",
"42347404": "ID: 42347404\nTitle: The Particle Size Effect: Cytotoxicity and Cellular Uptake of Polystyrene Nanoplastics in Human Keratinocytes.\nAbstract: Nanoplastics from plastic waste degradation pose a growing environmental health risk, yet size-dependent dermal effects remain poorly understood. This study investigated polystyrene nanoplastics of 50, 100, and 200 nm using ex vivo porcine skin and in vitro human keratinocyte models. Skin permeation, cellular uptake, viability, oxidative stress, inflammation, autophagy, and transcriptomic pathways were assessed. Enhanced nanoparticle penetration was observed in barrier-disrupted skin, primarily via hair follicles, with smaller particles showing greater intracellular accumulation. Transcriptomics revealed disruptions in oxidative stress, inflammation, endocytosis, and autophagy pathways. Specifically, 50 nm particles induced the strongest oxidative stress via Nrf2 activation and triggered sustained autophagy, leading to proliferation inhibition and time-dependent inflammation. In contrast, 100 nm particles caused moderate oxidative and inflammatory effects, whereas 200 nm particles provoked acute cytotoxicity, pronounced endocytosis, and an early inflammatory burst with subdued autophagy. These findings demonstrate that sub-100 nm PS NPs exhibit enhanced skin penetration in barrier-disrupted ex vivo models and induce pronounced oxidative stress, sustained autophagy, and proliferation inhibition in human keratinocytes. While these results suggest potential cellular mechanisms that may contribute to dermal toxicity, they do not directly demonstrate systemic absorption or long-term damage in vivo. Our observations provide a mechanistic basis for future in vivo investigations and highlight the need for caution when extrapolating in vitro findings to human health risks.",
"42359813": "ID: 42359813\nTitle: HIV-1 gp120-induced lysosomal stress responses are controlled by TRPML1 redox sensors.\nAbstract: Increased lysosomal stress responses (LSR) are commonly implicated in the pathogenesis of neurodegenerative disorders including HIV-1-associated neurocognitive disorders (HAND). The HIV-1 envelope glycoprotein gp120 causes LSR, increases levels of ferrous iron (Fe2+) in the cytosol and in mitochondria, disrupts the reactive species interactome (RSI), and increases neural cell death. Using SH-SY5Y human neuroblastoma and U87MG human astrocytoma cells treated with gp120 and pharmacological modulators, we evaluated redox signaling and LSR by redox-sensitive fluorescent probes, spinning-disk confocal microscopy, flow cytometry, Western blotting, and immunostaining. Here, we report that TRPML1, an endolysosome redox-sensitive cation channel, is mechanistically involved in gp120-induced neurotoxicity. TRPML1 was activated by gp120-induced increases in cytosolic reactive oxygen species (ROS) and resulted in release of Fe2+ from endolysosomes in levels sufficient to increase cytosolic levels of Fe2+ and ROS as well as decrease levels of hydrogen sulfide (H2S). Reduced glutathione normally buffers intracellular Fe2+, but gp120 decreased endolysosome glutathione levels and disrupted this regulatory control mechanism thereby promoting TRPML1-mediated Fe2+ efflux from endolysosomes. TRPML1 redox activation led to changes to the RSI in endolysosomes including increased ROS, lipid peroxidation, nitric oxide, and sulfane sulfur as well as decreased H2S. These changes were accompanied by increased cysteine oxidation of luminal proteins and endolysosome deacidification. Pharmacological inhibition of TRPML1 or knocking down expression levels of TRPML prevented these effects. Our findings suggest that TRPML1 redox activation controls gp120-induced endolysosome dysfunction and iron/redox imbalance, and further implicates TRPML1 in the pathogenesis of HAND.",
"42372357": "ID: 42372357\nTitle: Raloxifene and tamoxifen reshape the immunometabolic phenotype of TLRs-activated macrophages through AEBS inhibition and lysosomal stress.\nAbstract: Macrophages are key effectors of innate immune responses and infection control, relying on Toll-like receptors (TLRs) to sense pathogens and adopt immunometabolic anti-infective phenotypes. Raloxifene (RAL) and tamoxifen (TAM) are selective estrogen receptor modulators (SERMs) known to reprogram macrophage inflammatory responses via estrogen receptor-independent mechanisms, including NRF2 activation. Although drug repurposing approaches have highlighted anti-infective properties of these compounds, supporting host-directed mechanisms, the upstream targets and immune consequences of RAL and TAM in macrophages remain undefined. Here, we investigated the biological relevance and molecular determinants of SERM-mediated immune activity in TLR-activated macrophages. Our results show that RAL and TAM modulate inflammatory cytokine expression induced by TLR7/8, TLR4, and TLR2 stimulation. Specifically, these SERMs enhance IL 1\u03b2 maturation, despite reducing proIl1b mRNA levels, and increase TNF \u03b1 production, while restraining IL 6 expression. Notably, IL 6 repression is more pronounced with RAL and correlates with sustained NRF2 pathway engagement, suggesting a drug-specific immunoregulatory profile. Furthermore, RAL and TAM influence cytokine regulation through cholesterol-pathway remodeling consistent with AEBS inhibition, which was associated with PI3K-NRF2 activation and NRF2-related immunometabolic adaptation. In parallel, RAL and TAM promote lysosomal perturbations, leading to the regulation of proIl1b and Tnfa mRNA levels and to cathepsin B-associated caspase-1 activation and IL1\u03b2 production. Cathepsin B inhibition further enhances NRF2-target gene responses, suggesting functional crosstalk between lysosomal and NRF2-associated pathways. Overall, these findings indicate that RAL and TAM elicit an integrated immunometabolic reshaping of macrophage inflammatory phenotypes, through cholesterol-pathway remodeling and lysosomal stress, supporting SERMs as host-directed chemotherapeutic agents.",
"42374161": "ID: 42374161\nTitle: Dysregulation of the TFEB-ATP6V0C axis in microglia exacerbates \u03b1-synuclein pathology through impaired lysosomal acidification in Parkinson's disease.\nAbstract: Emerging evidence suggests that microglia exhibit dual regulatory roles in the pathogenesis of Parkinson's disease (PD); however, their precise function in \u03b1-synuclein clearance remains incompletely understood. Here, we provide compelling evidence that \u03b1-synuclein preformed fibrils (\u03b1-syn PFF) impair lysosomal acidification in microglia, leading to defective autophagic flux and disrupted \u03b1-syn degradation. This dysfunction further promotes the secretion of microglial extracellular vesicles (EVs), exacerbating disease pathology. Mechanistic investigations uncover that \u03b1-syn PFF directly interacts with ATP6V0C, a pivotal V0 subunit of V-ATPase. This interaction sterically hinders V0-V1 domain assembly, disrupting proton pump complex formation and reducing ATP6V0C expression. Functionally, ATP6V0C overexpression rescues lysosomal acidification deficits and facilitates \u03b1-syn degradation in vitro, while in vivo, ATP6V0C overexpression alleviates neurotoxicity and reduces phosphorylated \u03b1-syn aggregation in \u03b1-syn PFF mouse models. Further investigation identifies the PI3K-AKT-mTOR-TFEB pathway as a key regulatory axis of ATP6V0C-mediated lysosomal acidification in microglia. Notably, both TFEB activation and mTOR inhibition restore lysosomal acidity and upregulate ATP6V0C expression, thereby enhancing \u03b1-syn clearance. These findings establish the TFEB-ATP6V0C axis as a key determinant of microglial proteostasis, proposing targeted activation of this pathway as a promising strategy to mitigate PD progression.",

While oligonucleotide-based gene therapy holds promise for precision intervention, its clinical translation is hindered by inefficient cellular delivery and rapid lysosomal degradation. Here, we identified miRNA-223 as a pivotal regulator of IVDD, where its overexpression mitigated the inflammatory extracellular matrix (ECM) metabolic imbalance in NP cells in vitro. To overcome delivery barriers in vivo, we engineered an injectable multifunctional cell-penetrating peptide (CPP), R9-DOPA-DBCO, which spontaneously self-assembles with azido-modified miRNA-223 via bioorthogonal click chemistry to form nanocomplexes (R9-DOPA-miRNA223). These nanoparticles not only exhibited superior cell membrane penetration and lysosomal escape capabilities but also exhibited significant therapeutic efficacy in mitigating NP cell pyroptosis and restoring ECM metabolic homeostasis via the MKNK2/eIF4E/NOD-like signaling pathway, concomitantly attenuating IVDD progression in rat models. This direct and efficient delivery strategy not only has transformative potential for IVDD therapy but also broadens the conceptual and methodological framework for precision miRNA-based therapeutics.",

Here, we compared two red-fluorescent polystyrene spherical MNP preparations with nominal diameters of 80\u202fnm and 200\u202fnm, respectively, with red-fluorescent polyacrylonitrile Fiber MNPs (approximately 200\u202fnm in diameter and 2-3 \u03bcm in length) to define their effects on the corneal epithelium and ocular surface functional unit. In vitro, all MNP types were internalized by human corneal epithelial (HCE-T) cells with perinuclear accumulation and induced dose- and time-dependent cytotoxicity, including reduced viability, increased ROS, elevated TUNEL positivity, ZO-1 downregulation, and impaired epithelial migration; notably, 80\u202fnm PS MNPs elicited stronger early toxicity. In vivo, chronic topical exposure produced corneal epithelial damage, tear-film instability, conjunctival goblet-cell depletion, reduced corneal nerve density, and lacrimal gland inflammatory activation. Live imaging and scanning electron microscopy confirmed deposition, with Fiber MNPs showing surface embedding and disruption of corneal epithelial microvillar microarchitecture. Transcriptomic profiling with in vitro/in vivo validation showed enrichment of MAPK signaling and activation-associated changes in the MAP3K8-ERK/JNK/p38 axis, accompanied by a sustained pro-inflammatory transcriptional program, with more persistent inflammatory signaling in the Fiber MNP group. Together, these findings demonstrate particle type- and morphology-associated ocular surface toxicity of MNPs and support considering particle morphology together with polymer identity, size, and particle number in future ocular health risk assessment.",

While knowledge regarding detection and material characteristics has improved, the understanding of impact on cells remained unclear. As biological effects are initially caused by molecular interactions, consequently direct interactions with biomolecules, such as enzymes, are of particular relevance. In this occasion, effects may vary depending on the plastic type and particle properties. The specific aim of this study was to characterize the direct molecular interactions by means of selected model proteins and a variety of different nanoplastic particles. Therefore, the aim of the study was to exemplarily characterize \u03b1-amylase's (as a model enzyme) interactions with different nanoplastics and the resulting effects on enzyme structure and function, as well as cellular responses. The properties of the \u03b1-amylase-nanoplastic mixtures were analyzed using dynamic light scattering (DLS), Fourier-transform infrared spectroscopy (FTIR), fluorescence spectroscopy, and Phadebas amylase activity test. Additionally, Caco-2 cells were used as a model system for the human intestinal barrier and exposed to these complexes to evaluate cellular uptake through flow cytometry, microscopy, and viability testing. All applied nanoplastics interacted with \u03b1-amylase, forming complexes with adsorption affinities that depended on the particle type (PP \u226b PE > PET \u226b PLA). FTIR and fluorescence analyses showed particle-specific structural changes. Despite these differences in structural response, concentration-dependent enzyme inhibition was measurable, depending on the particle type. Uptake studies on Caco-2 cells indicated no internalization or cytotoxicity. These findings suggest that nanoplastics influence the enzyme structure and function based on their chemical properties, offering new insights into direct enzyme-nanoplastics interactions and their potential impacts on enzymes and cells.",
"42415176": "ID: 42415176\nTitle: Zinc-mediated lysosomal activation by 1H10 enhances autophagy and attenuates tau pathology in Alzheimer's disease models.\nAbstract: Impaired autophagic flux and lysosomal dysfunction contribute critically to the accumulation of pathological protein aggregates in Alzheimer's disease (AD). Emerging evidence suggests that intracellular zinc dynamics regulate lysosomal function by modulating processes such as acidification and lysosomal biogenesis. We previously identified 1H10 as an AMP-activated protein kinase (AMPK) inhibitor and subsequently demonstrated its zinc-binding capacity and ability to regulate intracellular zinc homeostasis. Building on our prior findings that intra-lysosomal zinc promotes acidification and activates transcription factor EB (TFEB), we investigated whether 1H10 enhances lysosomal function through zinc mobilization in neurons, thereby improving autophagy and reducing pathological protein accumulation. In primary cortical neurons, 1H10 increased lysosomal abundance and enhanced lysosomal degradative capacity in a zinc-dependent manner, as demonstrated by increased cathepsin B activity and DQ-BSA degradation. It alleviated lysosomal dysfunction induced by v-ATPase inhibition and promoted autophagic flux, leading to reduced accumulation of amyloid-\u03b2 (A\u03b2) and tau in neuronal models. In 5XFAD mice, 1H10 treatment showed trends toward improved spatial learning in the Morris water maze, reduced tau phosphorylation at Thr205 and Ser214, normalized LC3-II levels, and restored autophagic-lysosomal homeostasis, without significant changes in extracellular amyloid plaque burden. These findings indicate that zinc-mediated lysosomal activation by 1H10 enhances the autophagy-lysosomal pathway and attenuates tau pathology in AD models, suggesting that targeting lysosomal function may represent a potential therapeutic strategy for neurodegenerative disorders characterized by impaired proteostasis.",

Inherent differences in these culture/exposure modalities, such as particle behavior and deposited dose, likely affect cellular responses. To investigate this, we exposed submerged human bronchial epithelial cells (BEAS-2B) to polystyrene (PS) MNPs vs. aerosol exposure of ALI cultures. First, submerged bronchial epithelial cells (BEAS-2B) were exposed to suspensions of PS particles (50\u2009nm or 1\u2009\u00b5m) in four different applied concentrations (0.79-50\u2009\u00b5g/cm2; 24\u2009h). Second, BEAS-2B cells were cultured at ALI and exposed in a cloud system to PS 1\u2009\u00b5m particles (deposited dose: 55.4\u2009\u00b5g/cm2; 24\u2009h). Toxicity readouts focused on cytotoxicity (LDH release), inflammation (IL-8 release and transcriptional activation of inflammatory genes), and oxidative stress (DCFH-DA assay, antioxidant gene expression, and assessment of reduced/oxidized glutathione). In both models, PS exposure did not induce cell death, or an antioxidant response. However, NF-\u03baB transcriptional activity was strongly upregulated in submerged cells in response to both sizes of PS particles in a dose-dependent manner. Gene expression of CXCL1, CXCL2, and CXCL8 increased up to 7-fold after PS microplastic exposure (50\u2009\u00b5g/cm2) in the submerged model (which was less pronounced in response to PS nanoplastics) and 2-fold in the ALI model. In contrast, IL-8 secretion increased 1.6-fold for the ALI, but not the submerged model. Overall, both exposure modalities revealed an inflammatory response toward PS MNPs although with differences, likely due to significant differences in deposited dose. Very small plastic particles, called microplastics and nanoplastics (MNPs), are present in the air and can be inhaled into the lungs. To study possible health effects, scientists often expose lung cells to these particles in liquid (submerged) culture systems. However, this does not closely match how people are exposed through breathing. This study used a traditional liquid-based method and a more realistic system that exposes lung cells to plastic particles through the air. More specifically, human lung cells were exposed to polystyrene (PS) plastic particles of different sizes using either liquid exposure or an air\u2013liquid interface system, where particles were delivered as an aerosol, similar to inhalation. The researchers looked for signs of cell damage, inflammation, and oxidative stress. The results showed that the plastic particles did not kill the cells and did not cause oxidative stress in either exposure method. However, both methods caused signs of inflammation, which is a normal response of the body to foreign substances. In the liquid-based system, inflammation-related genes were strongly activated. In the air-exposed system, gene activation was weaker, but cells released higher levels of an inflammatory signaling protein. Importantly, the air-based exposure better reflects how people actually breathe in particles and avoids some problems linked to liquid-based testing. This study shows that there are differences in cellular responses to MNPs depending on the dose, particle behavior and culture system, which are all connected to each other.",

Anti-vascular endothelial growth factor agents, such as Bevacizumab (Beva), offer high specificity and low side effects. However, their limited ability to penetrate the corneal barrier necessitates invasive administration, significantly restricting their clinical application. Herein, we engineered (Beva&C\u2082G\u2082R\u2089)@Zn nanoparticles formed by co-assembling Beva, C\u2082G\u2082R\u2089 peptide and Zn2+, which decrease in size over time, as an efficient strategy for noninvasive Beva delivery across the corneal barrier to treat CNV. By combining various technologies (DLS, TEM, XPS, FTIR, and computer simulation), we discovered that the coordination between Beva and Zn2+ drives the nanoparticle formation, while the C\u2082G\u2082R\u2089 peptide facilitates its size evolution. Compared to size-stable nanoparticles of Beva@Zn and (Beva&R\u2089)@Zn, (Beva&C\u2082G\u2082R\u2089)@Zn nanoparticles exhibit rapid cellular internalization, efficient lysosomal escape, and effective corneal barrier penetration, leading to efficiently inhibit HUVEC cell migration and tube formation. Importantly, in a rat alkali-burned CNV model, (Beva&C\u2082G\u2082R\u2089)@Zn nanoparticles exhibited superior efficacy in inhibiting corneal neovascularization compared to size-stable nanoparticles, with the lowest inflammation index.

NHBEs responded differently to exposures of polyamide (PA) or polyvinyl chloride (PVC) particles at nominal doses between 0.003 and 0.100\u00a0\u00b5g/cm2. PA particles\u2009<\u20091\u00a0\u03bcm (but not those\u2009>\u20091\u00a0\u03bcm) induced dose-dependent cell death, increased IL-8 secretion and decreased MCP-1 secretion. PVC particles (<\u20091\u00a0\u03bcm and 1-5\u00a0\u03bcm) induced cell death at lower concentrations than PA particles. Also, an increased IL-8 secretion and decreased MCP-1 secretion was observed for PVC particles in all size fractions (<\u20091\u00a0\u03bcm, 1-5\u00a0\u03bcm and 5-10\u00a0\u03bcm). Comparison of nebulization versus quasi-ALI exposure indicated differences related to the exposure method, but further experimental assessment is needed for definite conclusions and to ensure that the obtained data is relevant for toxicological effects occurring in humans. Our results indicate that PA and PVC particles increase IL-8 secretion and, PA only, decreases MCP-1 secretion. It needs to be established whether these effects on cytokines also indicate an activation of immune cells.

Celastrol (CEL), a potent natural compound, is a promising candidate for NASH due to its lipid-modulating, anti-inflammatory properties, and antioxidative properties. However, its clinical translation is severely hindered by poor oral bioavailability and a narrow therapeutic window stemming from significant toxicity. To overcome these limitations, we present the design and fabrication of novel, carrier-free CEL nanoparticles stabilized through natural polysaccharide self-assembly. This innovative formulation strategy is aimed at substantially enhancing the oral bioavailability of CEL, thereby augmenting its therapeutic efficacy in NASH while mitigating associated adverse effects. In this study, we developed a polysaccharide-CEL supramolecular depot comprising 42 distinct nanoassemblies for oral delivery in NASH, identifying chondroitin sulfate (CS) as the optimal polysaccharide adjuvant. The resulting CS/CNA formulation markedly improved oral absorption, with a 3.12-fold increase in observed systemic exposure based on AUC(0-t) compared with free CEL. Inhibitor-based mechanistic studies suggested that CS/CNA transport across intestinal epithelial cells may involve multiple endocytosis pathways and partial lysosomal escape. In a murine model of NASH, CS/CNA demonstrated potent therapeutic efficacy by modulating hepatic inflammation and reducing lipid accumulation. Critically, the nanoassembly exhibited a favorable safety profile, mitigating the toxicity associated with free CEL. By enhancing therapeutic efficacy while reducing adverse effects, this strategy effectively widens the therapeutic window for celastrol. This work establishes CS/CNA as a promising oral therapeutic candidate and provides a robust platform for advancing the clinical potential of CEL for NASH management.",

Although combinatorial strategies targeting these pathological factors hold therapeutic promise, their clinical translation is constrained by the lack of effective delivery systems. In this study, we designed a mannose-functionalized poly(aspartic acid)-based nanocarrier bearing quaternary ammonium and boronic acid groups (MDA/QPABA) for the targeted delivery of microRNA-223 (miR-223). The system exploits charge-driven self-assembly to form stable nanoparticles with high loading efficiency, favorable colloidal stability, and tunable surface properties. The mannose moieties enable specific recognition by mannose receptors on target cells, facilitating cellular uptake and subsequent lysosomal escape. The resulting MDA/QPABA/miR-223 nanoparticles demonstrated pronounced anti-inflammatory, antioxidant, and anti-angiogenic activities in vitro. In a laser-induced CNV mouse model, they effectively reduced inflammatory and angiogenic cytokines, suppressed pathological neovascularization, restored retinal and choroidal structure, and preserved photoreceptor function, with an excellent biosafety. These findings highlight the potential of rationally engineered poly(aspartic acid)-based nanoarchitectures with tailored surface chemistry and biointerfacial properties for multifunctional nucleic acid delivery in nAMD therapy.",

Pathologically, PD is linked to the aggregation of \u03b1-synuclein, mitochondrial and lysosomal stress, and chronic neuroinflammation. This chapter integrates the genetic and epigenetic framework of Parkinson's disease, encompassing rare monogenic factors such as SNCA, LRRK2, GBA1, PINK1, and PRKN that converge on proteostasis disruption, compromised mitophagy, and lysosomal dysfunction, alongside polygenic susceptibility that may be exacerbated by environmental influences. Epigenetic dysregulation further influences susceptibility and disease progression: altered DNA methylation and hydroxymethylation at PD-relevant loci such as PARK7 and NR4A2, maladaptive histone regulation (including increased HDAC2/3 activity), and non-coding RNA networks (miR-7, HOTAIR, circSNCA) that modulate \u03b1-synuclein expression, inflammatory pathways, mitochondrial dynamics, and clearance mechanisms. Sex dimorphism is emphasized as a biologically significant modifier, with males exhibiting a higher incidence and accelerated progression in numerous cohorts, whereas estrogen-associated signaling may provide neuroprotection through increased dopamine biosynthesis, enhanced antioxidant capacity, and inhibition of microglial activation-effects that may diminish post-menopause. This chapter integrates recent advancements by linking mechanistic insights to translational potential, focusing on epigenetic biomarkers and disease-modifying techniques designed to restore lysosomal function, rectify dopamine processing, and strategically exploit hormone pathways.",
"42451740": "ID: 42451740\nTitle: Lysosomes in Ferroptosis: Regulatory Mechanisms and Molecular Targets.\nAbstract: Ferroptosis is a regulated form of cell death characterized by iron-dependent lipid peroxidation and membrane damage, with broad relevance to human disease. Accumulating evidence suggests that ferroptosis is governed by coordinated organelle-level regulation, among which lysosomes have emerged as central hubs. By controlling endolysosomal iron processing, transport, and degradation pathways, lysosomes shape the intracellular distribution and reactivity of iron, thereby modulating iron-driven lipid peroxidation. The acidic, iron-rich microenvironment and limited local antioxidant capacity render lysosomal membranes highly susceptible to oxidative injury, positioning lysosomes as initiation and amplification sites of lipid peroxidation. Meanwhile, lysosome-dependent selective autophagy pathways actively remodel iron homeostasis, lipid metabolism, and cellular antioxidant defenses, thereby dynamically modulating ferroptotic sensitivity. Mitochondria-lysosome crosstalk further redistributes iron, reactive oxygen species, and lipid substrates, linking lysosomal activity to interorganelle control of ferroptosis. Lysosomal stress-responsive signaling also coordinates metabolic adaptation and redox control. This review summarizes and integrates current evidence on lysosome-centered mechanisms that organize iron metabolism, lipid peroxidation, selective autophagy, organelle crosstalk, and stress-responsive signaling during ferroptosis, and further discusses their disease-specific roles, therapeutic potential, and translational challenges.",

Here, we propose an \"Alkaline-Hammer\" strategy that combines pH modulation with alkaliptosis induction to overcome these obstacles. We engineered alkalizing sodium bicarbonate nanoparticles (JTC801-NaHCO3@TPGS NPs) using a thin-film hydration method. Upon delivery, these nanoparticles neutralize the acidic TME through sustained NaHCO3 release, while JTC801, a selective opioid receptor-like 1 (ORL1) antagonist, activates the NF-\u03baB pathway to downregulate carbonic anhydrase IX (CA9). This dual action synergistically enhances intracellular alkalinization and induces alkaliptosis. Furthermore, we developed a laparoscopic intratumoral injection system to achieve precise delivery of JTC801-NaHCO3@TPGS NPs in orthotopic pancreatic tumor models. This strategy increased CD8+ T cells infiltration, reduced immunosuppressive populations (Tregs, MDSCs, and M2 macrophages), and elicited immunological memory, thereby converting immunologically \"cold\" tumors into \"hot\" ones without evident systemic toxicity. These findings underscore the potential of localized alkaliptosis induction as a promising immunotherapeutic approach for pancreatic cancer.",
"42456394": "ID: 42456394\nTitle: Defective lysosomal acidification promotes chondrocyte senescence and autophagic flux stagnation in geriatric osteoarthritis.\nAbstract: Geriatric osteoarthritis (G-OA) represents a senescence and metabolism-driven pathobiological phenotype, closely associated with ageing. Although lysosomal dysfunction is increasingly recognized as a cardinal feature of age-related diseases, most current therapeutic strategies primarily target upstream regulators of autophagy, particularly the PI3K/AKT/mTOR pathway. However, this approach may be limited in aged chondrocytes, where the efficiency of autophagic degradation is already compromised. With ageing, reduced vacuolar ATPase activity and the accumulation of intralysosomal lipofuscin may impair lysosomal acidification and degradative capacity. As a result, even when autophagy is pharmacologically stimulated, the clearance of autophagic cargo remains inefficient. This imbalance leads to the accumulation of undegraded autophagosomes, contributing to cellular stress and impaired autophagic flux. Importantly, lysosomal dysfunction under these conditions has increasingly been associated with the amplification of the senescence-associated secretory phenotype (SASP), activation of the NLRP3 inflammasome, and subsequent macrophage dysregulation. These interconnected processes may further exacerbate joint degeneration in G-OA. This review identifies lysosomal restoration as a potential therapeutic intervention point for overcoming downstream autophagic impairment in G-OA. Enhancing lysosomal acidification and degradative function may help re-establish effective autophagic flux and improve disease outcomes. Although several components of this proposed mechanistic framework require direct experimental validation in aged chondrocytes, the model provides a biologically plausible and testable basis for future investigations into lysosome-targeted therapeutic strategies for G-OA.",
"42465492": "ID: 42465492\nTitle: E2F1 Drives Endothelial Arterial Programming in Pulmonary Arterial Hypertension.\nAbstract: Pulmonary arterial hypertension (PAH) is driven by maladaptive endothelial remodeling, but the transcriptional regulators that couple proliferative stress to arterialized endothelial states remain incompletely defined. E2F transcription factor 1 (E2F1) is classically viewed as a cell-cycle regulator; whether E2F1 functions as a disease-driving node that promotes endothelial arterial programming in PAH remains unknown. We integrated human PAH lung transcriptomic analyses, deconvolution-based endothelial-state scoring, and complementary mouse and rat PH models with bulk RNA-seq, single-cell RNA-seq, pseudotime analysis, and CellChat inference. E2F1 function was tested using adenoviral E2F1 overexpression, pharmacological pan-E2F inhibition with HLM006474, and genetic E2f1 loss on a tamoxifen-inducible endothelial Egln1 -deletion background. In PAH lungs, E2F1 was increased and arterial endothelial cell (AEC) fraction and expanded arterial program scores were elevated. Similarly, Egln1 Tie2Cre lungs showed increased E2F1, induction of arterial remodeling genes, and activation of an E2F target program. Genetic loss of E2f1 reduced right ventricle systolic pressure, right ventricle hypertrophy, vascular remodeling, and distal muscularization in Egln1 -driven PH mice model. Bulk RNA-seq showed suppression of E2F, mitotic, epithelial mesenchymal transition, and extracellular matrix-remodeling programs. Single-cell RNA-seq showed reduced AEC accumulation, normalized CAP1/CAP2 distribution, and reduced progression along the CAP1-AEC trajectory. CellChat analysis identified loss of an arterial communication hub, including reduced ECM, VEGF, and Notch signaling when E2F1 is loss. Conversely, E2F1 overexpression in human lung microvascular ECs increased proliferation, activated E2F/cell-cycle and Notch/arterial programs. Pharmacological inhibition of E2F via HLM006474 suppressed endothelial proliferation and attenuated Egln1 -driven and MCT-induced PH, including reversal of established MCT-PH. E2F1 acts as a disease-relevant transcriptional factor linking endothelial cell-cycle activation to arterial programming, matrix and angiogenic communication programs, and pulmonary vascular remodeling. Genetic or pharmacological E2F inhibition mitigates experimental PH, supporting E2F1 as a therapeutic target in PAH. 1. This study identifies E2F1 as a previously unrecognized driver of PAH rather than only a downstream marker of cell-cycle activation.2. Genetic loss of E2f1 rescues hemodynamic and structural features of Egln1-driven PAH, and pharmacological E2F inhibition attenuates both Egln1-driven and monocrotaline-induced PH.3. Mechanistically, E2F1 links endothelial proliferation to Notch-associated arterial programming, AEC accumulation, and CAP1-to-iAEC-to-AEC trajectory progression. 1. E2F1 defines a tractable transcriptional node that integrates proliferative stress with arterial endothelial reprogramming, a core pathological feature of PAH vascular remodeling.2. Pan-E2F small-molecule inhibitors, several of which are in development for oncology, may be repurposable for PAH if E2F1-dependent endothelial arterial-programming signatures identify responsive disease states.3. Plasma- or tissue-based readouts of E2F1 activity may identify PAH patients most likely to benefit from E2F-directed therapy.",
"42465729": "ID: 42465729\nTitle: Impaired consolidation of spatial memory during sleep in patients with leucine-rich glioma-inactivated 1-associated limbic encephalitis.\nAbstract: Sleep promotes the systems consolidation of hippocampus (HC)-dependent spatial memories by reprocessing of previously encoded hippocampal representations. Hippocampal reprocessing involves pattern separation and pattern completion as central hippocampal functions performed by the dentate gyrus (DG) and cornu ammonis region 3 (CA3), respectively. The leucine-rich, glioma inactivated 1 (LGI1)-associated limbic encephalitis (LE) is an autoimmune brain disorder particularly affecting the DG and CA3 regions, thereby impairing hippocampal function. We studied 15 LGI1 patients (and matched healthy controls) to examine hippocampal contributions to the sleep-associated consolidation of spatial memory. Spatial memory was assessed using the virtual Morris water maze (VWM) during learning before nocturnal sleep. Spatial retrieval of target locations (as indicated by dwell time in target area) was tested in the next morning, with separate trials testing pattern separation and pattern completion functions, as well as place memory precision and reversal learning capabilities. Leucine-rich, glioma inactivated 1-associated limbic encephalitis (LGI1-LE) patients were able to learn and retrieve spatial locations, albeit to a lesser extent than controls. Recall of place memories was decreased in LGI1-LE patients in comparison with learning performance before sleep and with healthy controls, especially in trials assessing pattern separation. Moreover, at recall, LGI1 patients showed a less flexible adaptation to the reversal learning task, in comparison with the controls. Sleep quality, macro-sleep architecture and EEG slow oscillations (SOs) and spindles were comparable in both groups. However, in LGI1-LE patients, phase-amplitude coupling of SO-spindle events appeared diminished although the group difference did not remain significant after correction for multiple comparisons. In addition, a negative correlation between spindle density and retrieval of target locations was observed. Magnetic resonance imaging confirmed smaller volumes of the HC and its subfields (subiculum, CA1, CA3, DG) in the patients. Divergent structure-function relationships emerged between patients with LGI1-associated encephalitis and healthy controls: In patients, larger volumes of DG and CA3 were associated with weaker sleep-dependent consolidation but greater stability under cue deprivation. In controls, larger hippocampal, CA1, and subicular volumes correlated with better memory retrieval and reversal learning performance. Our results show an impaired sleep-associated consolidation of spatial memory in LGI1-LE patients highlighting the involvement of DG and CA3 areas in sleep-associated spatial memory formation and cognitive flexibility.",
"42466305": "ID: 42466305\nTitle: Non-uniform cycling of Li metal batteries: Impacts to life and performance.\nAbstract: Advances in cell design have improved lithium-metal battery (LMB) cycle life, but few studies assess performance under discharge profiles representative of real-world use. These profiles, which are often overlooked due to the complexity and risk of misinterpretation, can hinder accurate analysis or even prevent publication. Realistic discharge profiles include high currents during acceleration, current reversal during regenerative braking, and low steady currents at cruising speed. This work examines LMB performance using localized high-concentration electrolytes (LHCEs) under dynamic cycling, focusing on acceleration and regeneration pulses. These profiles bridge practical usage and controlled conditions for reproducible trends. Single-layer pouch cells are tested with LHCEs of lithium bis(fluorosulfonyl)imide (LiFSI), 1,2-dimethoxyethane (DME), with either 1,1,2,2-tetrafluoroethyl 2,2,3,3-tetrafluoropropyl ether (TTE) or bis(2,2,2-trifluoroethyl) ether (BTFE). The inclusion of pulsing dramatically alters the failure of the cells and increases cell-to-cell variability. Increasing the ionic conductivity and electrolyte volume decreases cell-to-cell performance variability. Cells with LHCE-BTFE exhibit more consistent cycling capacity behavior and fewer performance metric fluctuations, such as a rise of polarization or peak cell pressure, under non-uniform cycling compared to LHCE-TTE. These findings suggest that rapid transition from benchtop testing to real-world deployment for LMBs will require the inclusion of more realistic cycling conditions.",

Its acetyl group enables transport via monocarboxylate transporters, supporting blood-brain barrier penetration and efficient cellular uptake. Inside cells, levacetylleucine is metabolised by acylases, generating elevated levels of L-leucine that enhance mitochondrial bioenergetics and is thought to ameliorate lysosomal dysfunction indirectly. Here, we describe a direct effect of levacetylleucine on lysosomal regulation through modulation of TFEB, the master transcription factor for lysosomal and autophagy genes. Levacetylleucine rapidly alters TFEB translocation between the cytoplasm and the nucleus in a biphasic, homeostasis-restoring manner. In wild-type HeLa cells, levacetylleucine promotes TFEB activation and nuclear localisation. However, in NPC1 disease models, where we show that TFEB is over-activated and enriched in the nucleus due to lysosomal stress, levacetylleucine reduces nuclear TFEB and restores a more normal cytoplasmic-to-nuclear balance. These effects occur at clinically relevant concentrations associated with lysosomal storage reduction. The effects of the drug are stereospecific: while the L-enantiomer is active, the D-enantiomer and racemate show no effect, revealing the antagonistic properties of the D-enantiomer. This bidirectional normalisation of TFEB activity highlights a direct mechanism through which levacetylleucine modulates lysosomal and autophagic pathways in the HeLa cell model, giving mechanistic insight into its therapeutic potential in NPC, and also across diverse neurological and neurodevelopmental disorders.",

However, state-of-the-art electrical switching of MTJs remains constrained to hundreds of picoseconds, leaving a substantial gap between memory and processors. Here, we experimentally demonstrate field-free switching of three-terminal MTJs using picosecond electrical pulses driven by spin-orbit torque (SOT), surpassing the speed limit by an order of magnitude. We further use voltage-gated (VG) effect to probe SOT switching mechanisms over wide pulse-width ranges and identify a nonmonotonic VG-SOT efficiency. While the efficiency is pronounced under long-pulse excitation, it diminishes in the subnanosecond regime but reemerges as the pulse width scales down to 13.2 ps, yielding an energy consumption about 30 fJ per bit. Micromagnetic analysis reveals that, from dc to picosecond timescale, the dominant magnetization switching dynamics evolve from thermally activated reversal to incoherent precession to coherent precession. These results establish picosecond VG-SOT as a pathway toward ultrafast and energy-efficient memory and logic.",

Transcranial photobiomodulation (tPBM), a non-invasive neuromodulatory intervention for neuroprotection and functional restoration, has emerged as a promising therapeutic strategy. This study aimed to evaluate the therapeutic efficacy of tPBM against HH-induced spatial cognitive dysfunction and elucidate the underlying neurobiological mechanisms. Spatial learning and memory were assessed using the Barnes maze. Regional cerebral blood flow dynamics were evaluated using diffuse reflectance spectroscopy and laser Doppler flowmetry. Additionally, histological examination, transcriptome sequencing, and molecular biology analyses, were integrated to delineate the biological mechanisms and identify candidate signaling pathways and molecular targets. Barnes maze performance demonstrated that tPBM significantly ameliorated HH-induced deficits in spatial learning and memory. Mechanistically, tPBM modulated hemodynamic responses and enhanced cerebral oxygen-binding efficiency within the lateral parietal association cortex (LPtA). Furthermore, tPBM improved mitochondrial function by elevating cytochrome c oxidase activity and promoting ATP synthesis. Concurrently, tPBM suppressed hypoxia-inducible factor-1\u03b1 overexpression and microglial reactivity, reduced oxidative stress biomarkers, and augmented antioxidant enzyme activity. These molecular alterations were associated with preservation of synaptic structure, including reversal of dendritic spine loss. Transcriptome analysis further indicated that tPBM may preserves synaptic plasticity homeostasis by modulating the PI3K-Akt, cAMP-PKA, and calcium signaling pathways, with Adora2a identified as a potential therapeutic target. Collectively, these findings demonstrate that tPBM exerts neuroprotective effects against HH-induced spatial cognitive dysfunction by improving cerebral hemodynamics, enhancing mitochondrial function, attenuating neuroinflammation and oxidative stress, and preserving structural synaptic plasticity.",

Lotus leaf (Nelumbo nucifera Gaertn.) is a traditional edible and medicinal plant, and its calcined derivative, Heyehui (Hyh), has been documented for anti-obesity effects since the Ming Dynasty. However, the chemical composition and molecular mechanisms of Hyh against diet-induced obesity (DIO) remain largely uncharacterized. This study aimed to identify the chemical constituents and quantify the key bioactive components of Hyh, validate its anti-obesity efficacy in a DIO mouse model, and elucidate the underlying molecular mechanisms, thereby providing modern scientific evidence for its traditional application in anti-obesity therapy. Hyh composition was profiled by UPLC-MS, UV-Vis, and HPLC. DIO mice received Hyh intervention for 8 weeks; body weight, obesity indices, and serum glucose-lipid parameters were then assessed alongside histopathological examinations. The LEP/AMPK/ACC pathway and lipid synthesis factors were quantified by ELISA, immunofluorescence, qRT-PCR, and Western blot. Active components targeting LEPR were screened via molecular docking and DeepDrugDiscovery. Nuciferine and quercetin were further evaluated in 3T3-L1 adipocytes with shLEPR knockdown and Compound C validation. Intestinal barrier integrity and gut microbiota were analyzed by 16S rRNA sequencing. Fecal SCFAs were quantified by GC. Hyh was rich in alkaloids and flavonoids, with high nuciferine and quercetin contents. Hyh-treated DIO mice exhibited significantly reduced body weight, Lee's index, abdominal circumference, and body fat, accompanied by improved serum glucose-lipid profiles. Histologically, adipocyte shrinkage, decreased hepatic lipid deposition, and downregulated lipid synthesis factors were observed in adipose and liver tissues. Hyh activated the LEP/AMPK/ACC axis, promoting fatty acid \u03b2-oxidation; nuciferine and quercetin were identified as the key mediators, as evidenced by shLEPR knockdown and Compound C reversal. Hyh also upregulated occludin, claudin1, and ZO-1 in the duodenum, restored intestinal barrier integrity, suppressed CD36 and FATP4, increased gut microbial diversity, elevated fecal SCFA levels, and enriched genera such as Rikenella, which negatively correlated with obesity indicators. Hyh, with nuciferine and quercetin as its principal active constituents, ameliorates obesity and metabolic disorders in DIO mice through a multi-target mechanism that encompasses suppression of lipid synthesis, activation of fatty acid \u03b2-oxidation, repair of the intestinal barrier, remodeling of the gut microbiota, and elevation of short-chain fatty acid levels. The present study characterized the chemical composition of Hyh and elucidated its anti-obesity mechanisms, thereby providing a modern scientific basis for its traditional application. Although its clinical efficacy remains to be validated in future trials, Hyh demonstrates considerable potential as a natural anti-obesity agent.",

While there are specific benefits in reversal for TBI patients on warfarin, the impact has not been clearly shown in DOAC populations. This study evaluated radiographic and clinical outcomes among patients with isolated mild TBIs to determine whether DOAC usage or its reversal confers measurable differences in early outcomes. We conducted a retrospective review of adults (18 to 99\u00a0y) with isolated mild TBI (Glasgow Coma Scale: 13 to 15) after ground-level falls at a Level I trauma center from 2016 to 2024. The primary outcome was radiographic hemorrhage progression, defined as >2-mm increase in hemorrhage or need for >2 head computed tomographies within 24 hours. Secondary outcomes included Glasgow Coma Scale decline, intensive care unit length of stay, neurosurgical intervention, thromboembolic events, disposition, and inpatient mortality. Multivariable logistic regression and propensity score matching were used to evaluate associations between DOAC usage, reversal therapy, and outcomes. Among 273 patients, 96 (35%) were taking a DOAC, and of these, 41 received four-factor prothrombin complex concentrate and 18 received andexanet alfa. DOAC patients demonstrated similar rates of radiographic progression, intensive care unit length of stay, and discharge disposition compared with non-DOAC patients. In multivariate analysis, DOAC usage was not associated with increased radiographic progression, measured by subdural hemorrhage growth (47.5% vs. 44.8%; p = 0.70) or increased need for >2 computed tomography scans (49.1% vs. 48.9%, p = 1.00). Among DOAC users, reversal was also not associated with improved radiographic progression or secondary outcomes. No significant outcome differences were observed between reversal with four-factor prothrombin complex concentrate and andexanet alfa. In isolated mild TBI after ground-level falls, DOAC usage was not associated with worsened clinical outcomes or increased radiographic progression. Pharmacologic reversal offered no measurable benefit. These findings support selective reversal in stable mild TBI.

We aim to validate echocardiographic predictors for tamponade and construct a simple imaging-based risk stratification model to guide prompt management plans. We retrospectively studied consecutive patients who presented with at least moderate pericardial effusion. Patients with atrial fibrillation, greater than moderate pulmonary hypertension, or mechanical ventilation were excluded. Patients were identified as having cardiac tamponade if the intrapericardial pressure was \u22657 mmHg. The following echocardiographic parameters, each assigned equal weight, were evaluated to create the E-TAP (Echocardiography in Tamponade Assessment to recommend Pericardiocentesis) score: (1) right atrial late diastolic collapse, (2) right ventricular early diastolic collapse, (3) discordant left and right ventricular measurement variation indicating ventricular interdependence, (4) mitral valve inflow E velocity variation >30%, (5) tricuspid valve inflow E velocity variation >60%, (6) left ventricular outflow velocity variation >20%, (7) inferior vena cava plethora, (8) reversal of diastolic flows of the hepatic vein in expiration, and (9) large pericardial effusion. Of the 254 patients, 134 had tamponade, with a mean E-TAP score of 6.0 +/- 1.8, compared to 3.0 +/-1.7 in those without tamponade (p<0.001). Adjusted logistic regression analyses showed that IVC plethora, TV inflow variation >60%, and LVOT flow variation >20% were independently associated with tamponade. An E-TAP score \u2265 5 best identified patients with tamponade with 80% specificity and 81% sensitivity. The novel E-TAP score was strongly associated with cardiac tamponade and may facilitate timely decision making for pericardiocentesis.",

This study investigates the use of dexmedetomidine (DEX) in cynomolgus macaques (Macaca fascicularis) as a potential alternative or adjunct sedative. Four experiments were conducted to determine: (1) the safety and efficacy of DEX as a sole sedative; (2) optimal dose combinations of DEX and KET; (3) a comparison of DEX/KET sedation outcomes to historical KET-only sedation data; and (4) a comparison of the sedation duration of DEX/KET combinations to KET alone. First, we evaluated escalating doses of DEX (0.02-4.04 mg/kg), and in 11 of 14 attempts, animals remained rousable and maintained posture for up to 90 minutes. Then, we used a fixed DEX dose (0.75 mg/kg) combined with escalating KET doses (1.0-2.252 mg/kg) to reduce overall KET exposure and successfully achieved 90 minutes of sedation. We then compared DEX/KET sedation outcomes to prior KET-only sedation records, revealing fewer instances of emesis, less food waste, and improved repairing success with DEX/KET. Finally, KET alone (10 mg/kg) or a DEX/KET combination (0.75 mg/kg DEX and 2.25 mg/kg KET) was evaluated for routine colony management procedures without atipamezole (ATI) reversal. The DEX/KET group exhibited significantly longer sedation durations with reduced hypersalivation and vomiting compared with the KET-only group. These experiments demonstrated that DEX alone was insufficient for sedation in macaques at the tested doses and had no adverse outcomes at significantly higher doses than previously reported. We recommend a DEX/KET dose of 0.75 mg/kg DEX and 2.25 mg/kg KET to provide sedation and reduce side effects (vomiting, food waste).",

Single-center, prospective, double-blinded, randomized controlled trial. Cardiothoracic operating theaters and intensive care unit of a tertiary care hospital in India. Pediatric (<14 years) patients undergoing elective cardiac surgery with CPB support. The HDR group received an initial test dose of 100 IU/kg of heparin, and an individualized ACT dose-response curve was constructed to determine the dose required to target an ACT of 480 seconds. Controls received standard 400 IU/kg of heparin. Protamine was given post-CPB per protocol in both groups. In this noninferiority trial, HDR-guided anticoagulation was assessed against conventional weight-based dosing for first-pass attainment of ACT \u2265480 seconds before CPB. Target ACT was achieved in 72.2% (26/36) of HDR patients versus 83.3% (30/36) of controls (p = 0.396). Although HDR was associated with lower heparin exposure (260 v 420 IU/kg; p < 0.001) and protamine use (4.1 v 4.8 mg/kg; p = 0.002), as well as reduced 24-hour blood loss (5.2 v 6.5 mL/kg; p = 0.03) and packed red blood cell transfusion (6.8 v 8.2 mL/kg; p = 0.04), it did not demonstrate superior first-attempt ACT attainment. HDR-guided heparinization reduced heparin and protamine exposure and was associated with less bleeding and transfusion, but it did not improve first-pass ACT attainment. Because ACT is an imperfect surrogate for anticoagulant adequacy in children on CPB, these findings should be interpreted as ACT-guided dosing data rather than proof of equivalent anticoagulation. Larger multicenter studies with mechanistic and clinical endpoints are needed to confirm these results.",

Extracellular vesicles (EVs) have attracted growing interest as therapeutic vehicles owing to their inherent capacity to bypass the blood-brain barrier and deliver complex biological cargo to the central nervous system. Here, we examined whether large EVs (LEVs) derived from microglia with stable Sirtuin-2 knockdown (SIRT2-KD) confer the neuroprotective effects associated with SIRT2 inhibition. LEVs harvested from SIRT2-KD microglia were administered intranasally to APP/PS1 mice. We assessed microglial uptake of LEVs, along with subsequent changes in cellular metabolism, migration toward amyloid-beta (A\u03b2) plaques, phagocytic activity, and downstream pathological and behavioral outcomes. Proteomic and acetylomic profiling were employed to characterize the molecular cargo of LEVs-SIRT2-KD. LEVs-SIRT2-KD were readily internalized by microglia in vivo following intranasal delivery. Uptake of these vesicles markedly enhanced microglial bioenergetics, driving coordinated upregulation of both oxidative phosphorylation and glycolysis. This metabolic shift was accompanied by improved microglial recruitment to A\u03b2 plaques and increased phagocytic clearance. Consequently, treated mice showed reduced A\u03b2 plaque deposition, restored synaptic integrity, and reversal of cognitive deficits. Proteomic and acetylomic analyses revealed that LEVs-SIRT2-KD are selectively enriched in proteins and acetylation modifications linked to energy metabolism and phagocytic function, offering a mechanistic basis for the observed metabolic reprogramming. Together, these results identify LEVs as a critical vesicle subtype mediating the effects of SIRT2 knockdown and support a cell-free therapeutic strategy for AD centered on EVs-driven metabolic reprogramming of microglia.",

Here, we have developed a gas-shunting strategy by installing function-reversal ZnO materials into Ir-WO3 supports to diminish interference-gas responses and guide special aromatic hydrocarbons sensing. We find that ZnO materials can serve as reactively sacrificial sites for small-molecule H2S and CO and induce main aromatic hydrocarbons reactants into Ir-WO3 supports. This gas-shunting route guarantees highly-selective aromatic hydrocarbons sensing even in dual/ternary gas mixtures. Through integrating functional-opposite sensors into a system, the final sensing arrays achieve 100% classification accuracy for 10 single gases and 75 multi-compose gases with low training costs. In addition, we also show an autonomic \"cruise-detection\" system by equipping sensor arrays into robotic dog to accurately identify complex gases. Our findings emphasize sensors designs with selective features and may broaden integrated sensing-system analysis in complex environment.",

While the synthetic androgen 17\u03b1-methyltestosterone has been the industry standard for hormonal sex reversal for decades, environmental and consumer safety concerns, including potential carcinogenicity, have driven the search for sustainable alternatives. This critical review examines the full spectrum of approaches for producing monosex male tilapia, encompassing traditional methods (manual sexing, hybridization), hormonal treatments (synthetic steroids, aromatase inhibitors), biodegradable options (plant extracts like\u00a0Tribulus terrestris\u00a0and\u00a0Basella alba, animal by-products such as cattle and carp testes), and novel genetic strategies (YY male technology, genome editing). We highlight innovative biodegradable programs and discuss how nanoparticle-mediated drug delivery can enhance therapeutic efficacy. Furthermore, we explore how genome editing technologies like CRISPR-Cas9 offer groundbreaking potential for understanding and controlling sex determination systems.

In neurons, age-associated remodeling of repressive H3K27me3 chromatin may constrain genes needed for metabolic, synaptic, and stress-adaptive maintenance. In parallel, nicotinamide mononucleotide (NMN), an NAD+ precursor, has been reported to mitigate age-associated physiological and transcriptional changes in peripheral metabolic tissues. However, direct links between neuronal epigenetic aging programs and NMN-responsive transcriptional rescue remain unclear. Here, we performed a secondary integrative analysis of two public datasets: GSE190102, focused on age-associated neuronal H3K27me3 targets mapped through an activity-by-contact-style region-gene framework, and GSE85718, a long-term NMN transcriptomic dataset from skeletal muscle, liver, and white adipose tissue in mice. The analysis identified 23 genes shared between 21,155 aging H3K27me3-associated targets and 35 robust NMN-rescue genes. Because the aging target set was extremely broad, gene-level overlap was not statistically persuasive, and pathway-level convergence was absent. Under repressive-mark direction logic, 14 of the 23 shared genes were concordant, meaning that the NMN expression effect opposed the expected consequence of age-associated H3K27me3 remodeling. Objectives were to quantify overlap between neuronal age-associated H3K27me3 targets and robust NMN-responsive genes in peripheral metabolic tissues, classify shared genes by directional concordance under repressive chromatin logic, and identify high-priority mechanistic candidates. The analysis supports limited global convergence and nominates CPT2 as the leading convergent node for targeted validation. CPT2 emerged as the leading candidate. It showed age-associated H3K27me3 gain, a large K27me3 log-fold change of +3.504, NMN-induced expression increase in old animals, a positive NMN interaction coefficient of +0.201, and membership in the mitochondrial fatty-acid oxidation pathway. Within the downstream shared-gene mitochondrial analysis, CPT2 was the only mitochondrial-core gene, with nominal enrichment only. These findings do not support a broad reversal of neuronal epigenetic aging by NMN. Instead, they identify CPT2 as a biologically coherent and experimentally tractable candidate linking age-related repressive chromatin remodeling to NMN-responsive mitochondrial metabolism.",

The Confidential Enquiry into Perioperative Small Animal Fatalities (CEPSAF) established that cardiovascular and respiratory causes account for approximately 74% and 72% of perioperative deaths in dogs and cats, respectively, with 47% of canine and 61% of feline anesthetic-related deaths occurring in the postoperative period. PORD arises from a convergence of opioid-induced respiratory depression (OIRD), residual inhalant anesthetic effects, other drug-induced effects (e.g., neuromuscular blockade), and patient-specific vulnerabilities. PPCs encompass a broad spectrum of conditions, including atelectasis, aspiration pneumonia, pneumonia, hypoventilation, acute respiratory distress syndrome (ARDS), and respiratory arrest, with laparotomy studies reporting a PPC incidence of 22% in dogs. This narrative review synthesizes current evidence on the pathophysiology, risk factors, diagnostic approaches, prevention strategies, and treatment of PORD and PPCs in veterinary practice, incorporating insights from both veterinary-specific and translational human anesthesia literature, while explicitly identifying areas where veterinary-specific evidence remains limited. The importance of continuous monitoring during the postanesthetic period, multimodal analgesia to reduce opioid exposure, protective lung ventilation strategies, and early intervention is highlighted as a key strategy to improve outcomes, together with the unmet need for reversal-independent (\"agnostic\") respiratory stimulants capable of countering PORD irrespective of the causative agent.",
"42472143": "ID: 42472143\nTitle: Assessment of Changes in Diaphragm Thickness to Predict Extubation Outcomes After Prolonged Upper Abdominal Surgery.\nAbstract: Prolonged upper abdominal surgery causes postoperative pulmonary complications, such as weaning failure. The diaphragmatic thickening fraction (DTF) is regarded as the surrogate of the breathing workload and correlates well with diaphragm strength. Compromised diaphragm function negatively influences ventilation, leading to difficulty in weaning from a mechanical ventilator. The objectives of the study were to estimate the changes in diaphragm thickness and the best cutoff value that will predict extubation failure at the end of prolonged upper abdominal elective surgery. In this prospective observational study, 120 patients (aged 18-70 years) of either sex and with American Society of Anesthesiologists physical status I or II, scheduled to undergo upper abdominal surgery lasting four hours or more, were included. Patients taking more than 30 minutes to extubate from the time of administration of the reversal agent were categorized as failure to extubate. The DTF was assessed via ultrasonography.\u00a0 Results: Twenty-five (20.83%) patients had failed extubation. Sex (P = 0.001) and pre-extubation DTF (P < 0.001) were identified as significant variables distinguishing patients who were successfully extubated from those who failed extubation. Multivariate logistic analysis showed that female sex (odds ratio (OR) = 0.233; P\u00a0= 0.010) and pre-extubation DTF (OR = 1.071; P\u00a0= 0.001) were significantly associated with successful extubation. A pre-extubation DTF cutoff of >22.63% predicted successful extubation with a sensitivity of 88.04%, a specificity of 56.0%, and an area under the receiver operating characteristic curve (AUC-ROC) of 0.752 Conclusions: Diaphragmatic dysfunction is common after prolonged upper abdominal surgery, and DTF may help identify patients at risk of extubation failure.",

In this work, we computationally demonstrate a monolithic two-dimensional Ge2Sb2Te5 (GST) phononic crystal plate in which hexagonally patterned crystalline inclusions are embedded within an amorphous GST host, where the impedance contrast between the two phases opens a topological bandgap. Here we show that the overlap integral between an external excitation source and the Bloch eigenstates governs directional selectivity. The source position and phase determine which topological pseudospin channel is excited, enabling deterministic routing through spin-momentum locking. Our system exploits [Formula: see text] symmetry, which supports degenerate [Formula: see text]-type and [Formula: see text]-type orbital modes at the [Formula: see text] point serving as pseudospin degrees of freedom. When a single harmonic force is applied, it projects onto both pseudospin channels, yielding bidirectional propagation. By contrast, a quadrature phased force pair on neighboring inclusions generates a rotating displacement field whose coupling to one pseudospin state identically vanishes, locking propagation to a single direction. Swapping the force positions reverses the routing direction, and this reversal is spatially invariant across the interface, providing evidence of spin-momentum locking. By varying only the source configuration, the same interface operates as a bidirectional waveguide, unidirectional isolator, or selective router. These results demonstrate how spin-momentum locking can serve as an efficient mechanism for directional selectivity of topological interface states in monolithic structures, with relevance to on-chip acoustic signal routing and frequency-selective wave filtering.",

Starting from the two-particle nonequilibrium Green's function, we derive a general expression for the interaction energy in terms of the polarization propagators of the individual systems. The interaction energy admits a physically transparent decomposition into charge noise and charge dissipation contributions, providing a fluctuation-dissipation interpretation that generalizes the equilibrium London picture. Model calculations for coupled molecular junctions demonstrate that the applied voltage can enhance the attractive dispersion interaction by nearly an order of magnitude relative to equilibrium. In thermal equilibrium, the dispersion interaction is universally attractive, irrespective of the specific form of the nanostructure Hamiltonians or their coupling to reservoirs. Out of equilibrium, we introduce a generalized Kubo-Martin-Schwinger ratio that parameterizes the departure from detailed balance. We show that, in contrast to equilibrium, nonequilibrium conditions can lead to a repulsive dispersion interaction. Finally, we discuss the conditions under which population inversion in the electronic leads can drive a sign\u00a0reversal of the dispersion interaction.",

Protein kinase C (PKC) modulators can reverse HIV latency and could thus be useful \"Kick\" components in \"Kick and Kill\" approaches to a cure. However, PKC modulators also affect immune cell function, potentially limiting their clinical safety and utility. Here, using PKC isoform inhibitors in models of HIV latency and HIV-negative mononuclear cells, we determined the PKC isoforms involved in PKC modulator-mediated HIV latency reversal and immunomodulation (CD69 and CD4 expression, and inflammatory cytokine production). We found that inhibition of PKC \u03b1, \u03b2, \u03b3, \u03b4, or \u03b8 limited PKC-mediated HIV latency reversal to varying degrees. We also found that combinatorial PKC isoform inhibition significantly limited robust PKC modulator-mediated immune cell surface expression of CD69 and cytokine production. None of the pharmacologic PKC inhibitors affected PKC modulator-mediated downmodulation of T-cell surface CD4 expression. These results provide important insight into the isoforms involved in the various PKC modulator-mediated activities, including HIV latency reversal. Design of next-generation PKC modulators that are more selective for PKC \u03b1, \u03b2, and \u03b8 may allow for the partial functional decoupling of HIV latency reversal from immunomodulatory effects, and lead to safer and more effective PKC modulator-based latency-reversing regimens.IMPORTANCEHIV persists in long-lived, latently infected cellular reservoirs, which prevents the cure of the infection using currently available antiretroviral therapy alone. The \"Kick and Kill\" strategy proposes the use of latency-reversing agents (LRAs) to induce viral reactivation leading to reservoir elimination. Protein kinase C (PKC) modulators are one of the most potent classes of LRAs and operate through the activation of several PKC isoforms. Here, we demonstrate the contribution of various PKC isoforms to PKC modulator-mediated HIV latency reversal and immunomodulation. We identified PKC \u03b1, \u03b2, and \u03b8 as the isoforms important for latency reversal, while other isoforms, especially broad PKC isoform activation, had greater relative effects on immune cell activation and cytokine release. Together, these results define the pathways required for PKC-mediated HIV latency reversal and other important immunomodulatory effects and will thus inform the development of next-generation isoform-selective PKC modulator LRAs.",

Herein, we report for the first time the use of a phosphorylated nanocellulose biopolymer as a highly selective and environmentally benign depressant to overcome serpentine-induced interference in sulfide flotation, and elucidate the selective depression and interfacial mechanism. Phosphorylated cellulose nanofibers (P-CNF) and phosphorylated cellulose nanocrystals (P-CNC) were synthesized by introducing phosphate functional groups, resulting in a marked enhancement in pyrite flotation performance, with recoveries exceeding 88.0% and reaching 89.6% for P-CNF. The exceptional separation efficiency arises from the highly selective adsorption of phosphorylated cellulose on the serpentine MgOH plane, with a surface coverage of 96.32% on serpentine compared to only 0.28% on the pyrite surface. This pronounced selectivity induced a reversal of the serpentine surface charge, thereby transforming pyrite-serpentine interactions from electrostatic attraction to strong repulsion. Force-resolved atomic force microscopy measurements provided direct nanoscale evidence for this transition, revealing a dramatic reduction in adhesion forces from \u223c9.81 mN m-1 to \u223c1.25 mN m-1 (P-CNC) and \u223c0.10 mN m-1 (P-CNF). Moreover, phosphorylated nanocellulose promoted the flocculation of fine serpentine particles via polymer-bridging effects, leading to the enlarged aggregates and effective suppression of mechanical entrainment. This work establishes phosphorylated nanocellulose as a novel green depressant platform and provides molecular insights into interfacial interactions governing complex mineral separation, thereby enabling the rational design of sustainable reagents and advancing resource-efficient environmentally interfacial responsible mineral processing.",

However, the molecular mechanisms through which external physical stimuli disrupt these robust scaffolds remain poorly understood, particularly the residue-specific responses. Here, we systematically evaluated the structural collapse and mechanical attenuation of A\u03b2 fibrils and their K16 mutants, including the charge-reversal K16D and bulky K16W, under a 1.0\u00a0V/nm electric field (EF) using molecular dynamics (MD) simulations. We demonstrated that this external stimulus persistently disrupts the \u03b2-sheet hydrogen-bond network within the simulated recovery window and leads to a drastic reduction in Young's modulus driven by dipole-field misalignment. Notably, this response was highly mutation dependent since the K16D mutant exhibited severe orientation-dependent collapse due to an amplified electrostatic torque, whereas K16W maintained its structural resistance via enhanced steric packing. Furthermore, EF induced a sustained increase in the solvent-accessible surface area (SASA). These findings suggest that external EF can serve as a potent physical modulator to destabilize pathogenic amyloid aggregates, potentially overcoming the physical barrier of dense plaques, enhancing the penetration and efficacy of therapeutic agents.",

Herein, we report a redox-responsive prodrug nanosystem, SOL-SS-PTX, constructed by conjugating PTX to the bioactive natural polyisoprenoid solanesol (SOL) via a disulfide bond. Unlike conventional polymer- or lipid-based carriers, SOL simultaneously serves as the hydrophobic self-assembly driver and a pharmacologically active co-agent, enabling synergistic antitumor activity. The prodrug spontaneously self-assembles into uniform nanoparticles with an ultra-high drug loading of approximately 50% (w/w). D-\u03b1-Tocopheryl polyethylene glycol succinate (TPGS) is further incorporated to enhance stability and reverse MDR via P-gp inhibition. In a reductive tumor-mimetic environment, cumulative PTX release exceeded 80% within 48\u202fh, while less than 10% PTX leakage occurred physiological conditions. In vitro, SOL-SS-PTX/50%TPGS exhibited potent cytotoxicity against both sensitive (A549, HepG-2) and resistant (A549/MDR) cells, achieving a reversal resistance index (RRI) higher than that of the ester-linked control (2.75 fold). In H22 xenograft-bearing mice, the nanoformulation achieved a 69.7% tumor growth inhibition rate with no observable organ toxicity.

Even though there are three food and drug administration (FDA) approved drugs for treatment of IPF, these drugs are ineffective against reversal of the disease but rather can only reduce the progression of the disease. As a result, the median survival rate for IPF is extremely low and new therapeutic strategies are urgently needed. Krueppel-like factors (KLFs) are zinc finger containing transcription factors that control the outcome associated with various types of diseases, given their critical role in cellular differentiation and proliferation. The role of KLFs is very cell specific and as a result it finely balances the inflammation associated with various diseases. Even though different members of the KLF family have been reported to have a role in IPF, this review summarizes the role of KLFs in regulation of inflammation associated with idiopathic pulmonary fibrosis.",

Within the quasiclassical Green's function framework, we derive analytical expressions for the first- and second-harmonic spin Josephson currents. The interplay between Rashba spin-orbit interaction and the exchange field breaks inversion and time-reversal symmetries, generating additional cosine terms in the spin current-phase relations and a finite $\\varphi_{0}$ phase shift.
This phase shift induces an intrinsic asymmetry between forward and backward spin currents, leading to the SJDE without an external magnetic field. Numerical results show that the efficiency decreases with increasing metal thickness due to suppression of the second-harmonic component, while its dependence on spin-orbit interaction strength reflects competing effects between phase shift enhancement and harmonic suppression. These findings demonstrate that the interplay between harmonic components provides a mechanism for nonreciprocal spin transport without requiring suppression of spin-singlet correlations.",

However, the clinical significance and biological role of miR-361-5p in PCa remain unclear. The present study was conducted to investigate the molecular mechanisms in metastatic PCa by using various experimental methods in vitro and in vivo. miR-361-5p was significantly downregulated in PCa cells and tissues. Overexpression of miR-361-5p inhibited proliferation, migration, and invasion in vitro, and suppressed tumor growth and lung metastasis in vivo. Mechanistically, miR-361-5p directly targeted TWIST1, reducing its protein levels and transcriptional activity; restoration of TWIST1 rescued the metastatic phenotype, confirming functional targeting. Importantly, miR-361-5p also regulated SOX4 via TWIST1 and formed a negative feedback loop with SOX4, reinforcing the suppression of metastasis. This TWIST1/SOX4 axis drove a reversal of epithelial-mesenchymal transition, marked by increased E-cadherin and decreased Vimentin and Fibronectin expression. The present study, for the first time, suggests that miR-361-5p functions as a tumor suppressor in PCa by modulating the TWIST1/SOX4 axis and EMT. These insights offer new therapeutic avenues for targeting miRNAs in metastatic PCa.",

This study evaluates the outcomes of complete reversal to normal anatomy following failed gastric bypass. We conducted a retrospective case series of 13 patients (0.9% of 1,450 bypass patients) who underwent complete laparoscopic reversal to normal anatomy between 2020 and 2024. Indications included severe malnutrition after one-anastomosis gastric bypass (OAGB) (n\u2009=\u20095), intractable marginal ulcers after Roux-en-Y gastric bypass (RYGB) (n\u2009=\u20094), and severe dumping syndrome after RYGB (n\u2009=\u20094).

Data extraction and synthesis was performed according to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) checklist. Data were summarized and pooled effect estimates were presented. Outcome was mortality, and primarily with a follow-up limited to 3\u00a0months. A total of 8217 studies were screened; 8 were ultimately included, all observational, and including 8777 participants with documented reversal treatment. For the overall analysis, when all types of intracranial hemorrhage and all types of anticoagulants were included, reversal was associated with reduced mortality (RR 0.78 (95% CI 0.67-0.91); p\u2009=\u20090.002). This association was also seen in the subgroup analysis of 8639 participants with nontraumatic intracerebral hemorrhage on any oral anticoagulant (RR 0.77 (95% CI 0.64-0.94); p\u2009=\u20090.009), but not among the 3059 participants with intracerebral hemorrhage treated with only direct oral anticoagulants (RR 0.91 (95% CI 0.80-1.03); p\u2009=\u20090.15). Current evidence for reduced mortality following anticoagulant reversal in intracranial hemorrhage is limited and primarily derived from observational studies. Although pooled data suggest a potential treatment benefit across various types of intracranial hemorrhages and anticoagulants, most hemorrhage subtypes remain insufficiently studied. Going forward, there is a critical need for randomized clinical trials and additional well-controlled observational studies to determine which patients truly benefit from reversal treatment.",
"42478051": "ID: 42478051\nTitle: Cell-size heterogeneity acts as a regime-dependent mechanical switch for collective migration.\nAbstract: Cell-size heterogeneity is ubiquitous in epithelial tissues, yet the fundamental physical principles governing its impact on collective migration remain elusive. Here, we show that size heterogeneity acts as a regime-dependent mechanical switch: it enhances collective motility in solid-like tissues while strongly suppressing migration in fluidized ones. This reversal arises from a previously unrecognized energetic hierarchy that governs microscopic topological remodeling. By systematically quantifying the work required for cellular neighbor exchanges, we demonstrate that size diversity reshapes the tissue energy landscape. In heterogeneous tissues, larger cells function as mechanically constrained anchors that elevate local rearrangement barriers, stabilizing the tissue against topological fluctuations. Crucially, these emergent energetic constraints either compete with or reinforce shape-based structural changes depending on the mechanical state, dictating the overall rate of tissue remodeling. Together, our results establish a unified physical framework linking microscale size heterogeneity to the fundamental energetic cost of cell rearrangements, and suggest that cell-size distribution serves as an intrinsic tunable parameter that dictates the epithelial mechanical property and migratory potential across diverse physiological contexts.",
"42478981": "ID: 42478981\nTitle: Thirty Years of Minimally Invasive Colorectal Surgery at the Fundeni Clinical Institute: An Institutional Experience.\nAbstract: Background: Minimally invasive colorectal surgery has evolved considerably in our country over the past three decades, although its early adoption was slow and uneven in many centers. At the Fundeni Clinical Institute, this evolution began in 1995 with the first reported laparoscopic colorectal operation performed in Romania, marking the start of a gradual transition from the open approach to minimally invasive surgery for both colonic and rectal pathology. Methods: We conducted a retrospective institutional review, integrating historical milestones, published experience, and analysis of internal databases. Laparoscopic, robotic-assisted, and transanal techniques were evaluated, with emphasis on oncologic colorectal surgery and the progressive expansion of minimally invasive indications. Results: After an initial period of cautious and limited dissemination, minimally invasive colorectal surgery progressively expanded as surgical expertise and technological resources improved. The adoption of advanced laparoscopic procedures, including the laparoscopic reversal of the Hartmann procedure and various transanal techniques, reflected the extension of minimally invasive colorectal practice beyond selected cases to more complex colorectal surgery. Between 2012 and 2023, 2,447 rectal cancer resections were performed, of which 446 were minimally invasive. After discontinuation of the robotic program, laparoscopic surgery served as the sole minimally invasive approach and was paradoxically associated with a further increase in minimally invasive procedures, despite the absence of robotic surgery, without compromising oncologic or postoperative outcomes. Conclusions: The experience of the Fundeni Clinical Institute illustrates the successful maturation of minimally invasive colorectal surgery from an early pioneering stage to a stable and expanding practice. Despite initial limitations and the discontinuation of the robotic program, laparoscopic surgery became the main driver of minimally invasive procedures, enabling their extension to more complex cases without compromising oncologic or perioperative outcomes. This evolution highlights the institute\u00e2s role in consolidating minimally invasive colorectal surgery as a reliable standard in a high-volume center.",
"42479449": "ID: 42479449\nTitle: Does the Evidence Support High-Dose Liposomal Amphotericin B in the Treatment of Mucormycosis?\nAbstract: Guidelines recommend liposomal amphotericin B (L-AMB) at 5-10\u2005mg/kg/day as first-line therapy for invasive mucormycosis, but whether doses exceeding 5-6\u2005mg/kg/day improve outcomes enough to justify added nephrotoxicity and cost remains unclear. We critically appraised pharmacokinetic, preclinical, and clinical evidence from 58 publications, defining standard-dose L-AMB as 5-6\u2005mg/kg/day and high-dose (HD) L-AMB as >6\u2005mg/kg/day. Animal models show dose-dependent efficacy, but the only prospective trial (Ambizygo) examining HD-L-AMB was a single-arm pilot trial whose response rates were similar to historical 5\u2005mg/kg/day cohorts. Retrospective studies have not found survival benefit favoring HD L-AMB, with consistently higher rates of nephrotoxicity. Saturable pharmacokinetics and altered liposome distribution at doses >10\u2005mg/kg/day may explain this lack of benefit. Routine dose escalation beyond 5-6\u2005mg/kg/day is not supported by current evidence; early diagnosis, surgical debridement, and reversal of immunosuppression appear more critical. However, selected cases may still warrant higher L-AMB doses based on individualized risk-benefit assessment."
