RAW264.7 cells were randomly divided into the normal control group, oxidized low-density lipoprotein(ox-LDL) group, HLJDD group, simvastatin(simva) group, and RAW264.7-ERK5 gene knockout(ERK5-KO) group. According to the experimental protocol, cells in each group were treated for 24 h with normal control rat serum, ox-LDL, HLJDD-containing serum, or simva-containing serum. Apoptotic Jurkat cells were added to each group and co-cultured for 90 min. After removal of the supernatant, LC3-\u2161 labeling was performed to observe LAPosomes in macrophages, and the clearance of apoptotic Jurkat cells was assessed. The expression levels of phosphorylated(p)-ERK5, ERK5, LAP-related signaling molecules [T-cell immunoglobulin and mucin-domain-containing molecule-4(TIM-4), vacuolar protein sorting 34(VPS34), Beclin-1, RUN domain Beclin-1-interacting and cysteine-rich domain-containing protein(Rubicon), autophagy-related protein 5(ATG5), and autophagy-related protein 7(ATG7)], pro-inflammatory cytokines [interleukin-1\u03b2(IL-1\u03b2), interleukin-6(IL-6)], and anti-inflammatory cytokines [interleukin-10(IL-10), transforming growth factor-\u03b2(TGF-\u03b2)] were measured. RESULTS:: showed that, compared with the control group, the ox-LDL group exhibited decreased LAPosome percentage and reduced clearance of apoptotic cells, downregulated expression of p-ERK5, TIM-4, VPS34, Beclin-1, Rubicon, ATG5, and ATG7, increased IL-1\u03b2 and IL-6 levels, and no significant changes in IL-10 or TGF-\u03b2 expression. Compared with the ox-LDL group, the HLJDD and simva groups showed increased LAPosome percentage and enhanced apoptotic cell clearance, upregulated expression of p-ERK5, TIM-4, VPS34, Beclin-1, Rubicon, ATG5, and ATG7, decreased IL-1\u03b2 and IL-6 levels, and increased IL-10 and TGF-\u03b2 expression. Compared with the HLJDD group, the ERK5-KO group exhibited significantly reduced expression of ERK5 and p-ERK5, and all other indicators were reversed. In conclusion, HLJDD may ameliorate macrophage LAP dysfunction and exert anti-AS effects by activating ERK5."

"abstract_text": "ID: 42535557\nTitle: Role of Lipin-1 in Macrophage-Mediated Atherosclerosis: Is It Atherogenic or Atheroprotective?\nAbstract: Macrophages are central regulators of atherosclerosis, governing lipid accumulation, inflammatory signaling, and plaque stability. Lipin-1 is a multifunctional lipid-metabolic regulator that integrates cellular metabolism with inflammatory responses through its dual roles as a phosphatidic acid phosphatase enzyme and a transcriptional coregulator. However, its role in macrophage-driven atherosclerosis remains controversial. This review critically evaluates the domain-specific functions of lipin-1 and their impact on disease progression. Accumulating evidence indicates that lipin-1 exerts divergent, domain-dependent effects. The transcriptional coregulatory activity of lipin-1 promotes peroxisome proliferator-activated receptor/peroxisome proliferator-activated receptor \u03b3 coactivator 1-\u03b1 signaling, enhances fatty acid \u03b2-oxidation and oxidative phosphorylation, and supports interleukin-4-driven proresolving macrophage polarization. It also enhances efferocytosis, suppresses sterol regulatory element-binding protein-mediated lipogenesis, and reduces oxidized low-density lipoprotein-induced foam-cell formation. These effects are associated with reduced necrotic core formation, lower interleukin-23 signaling, diminished macrophage necroptosis, and improved plaque stability in experimental models. In contrast, the phosphatidic acid phosphatase enzymatic activity of lipin-1 activates diacylglycerol-dependent protein kinase C-extracellular signal-regulated kinase- activator protein-1 and toll-like receptor 4 signaling, promotes inflammatory eicosanoid production, enhances oxidized low-density lipoprotein uptake, impairs cholesterol efflux, and accelerates foam-cell formation and vascular inflammation. Myeloid-specific loss of phosphatidic acid phosphatase activity reduces lesion size and inflammatory burden while improving macrophage lipid handling. Collectively, current evidence supports a domain- and context-dependent role for lipin-1 in atherosclerosis. The transcriptional coregulatory function appears predominantly atheroprotective, whereas phosphatidic acid phosphatase enzymatic activity is proinflammatory and atherogenic. Selective modulation of lipin-1 activity in macrophages may therefore represent a promising therapeutic strategy to limit atherosclerosis progression while preserving inflammation-resolving pathways."

"error": "",
"abstract_text": "ID: 42558291\nTitle: IL-33 promotes efferocytosis by peritoneal macrophages by a mechanism associated with rapid granulocyte IL-13 production.\nAbstract: Resolution of inflammation is an active process that requires efferocytosis, the engulfment of apoptotic cells by macrophages, mediated by receptors such as MerTK. IL-33 is an alarmin that initiates type 2 immune responses, including increased production of IL-13, which promotes MerTK expression. The ability of IL-33 to promote efferocytosis in vivo was examined. Intraperitoneal administration of IL-33 to mice increased local MerTK+ macrophage numbers within 48h. MerTK+ macrophages were not similarly induced by free mitochondria, an alternative cell damage associated signal. Efferocytotic activity was increased rapidly in response to apoptotic thymocytes in IL-33-treated mice. The established inducer of MerTK expression, IL-13, was detected in peritoneal lavage fluid shortly after IL-33 administration. Peritoneal eosinophils expressed the IL-33 receptor and demonstrated both intracellular IL-13 by flow cytometry and significantly increased Il13 transcript expression following IL-33 treatment. In contrast, neither elevated IL-13 expression nor IL-13 protein secretion was observed in peritoneal lymphocyte populations within the first 6 hours after IL-33 administration. Primary cultures of bone marrow-derived mouse mast cells and eosinophils demonstrated IL-13 protein responses to IL-33 administration within 6\u00a0h. Mast cell-deficient Cpa3-Cre; Mcl-1fl/fl mice had significantly reduced IL-13 levels in the peritoneal cavity 3 hours after IL-33 administration when compared with mast cell-containing littermates. In contrast, IL-33-treated eosinophil-deficient \u0394dblGATA mice had similar levels of IL-13 at this time point as wild type controls. These data demonstrate that IL-33 promotes MerTK expression, critical for efferocytosis by macrophages, by a process associated with an early rapid local increase in IL-13 production to which mast cells are a substantial early contributor. These findings contribute to our understanding of clinical situations where elevated soluble IL-33 receptor (sST2) and/or lower mast cell numbers are associated with worse clinical outcome."

"abstract_text": "ID: 42555352\nTitle: Circulating cochlin LCCL domain binds to dying cells and enhances efferocytosis.\nAbstract: Clearance of dead cells by efferocytosis is a critical process for homeostasis, notably by limiting inflammation. Defective efferocytosis has been associated with autoimmune, neurodegenerative, and cardiovascular diseases, as well as chronic infections, making its regulation a potential therapeutic target. Here, we identify circulating cochlin LCCL (Limulus factor C, Cochlin, and Lgl1) domain as a regulator of efferocytosis. Using cell binding assay for recombinant cochlin LCCL domain, we establish its tropism for dead or dying cells of both immune and non-immune lineages from murine and human origins. By three independent functional assays, we demonstrate that endogenous and exogenous cochlin LCCL domain enhances macrophage efferocytosis in vitro and in vivo in lipopolysaccharide (LPS)-induced inflammation and intranasal Pseudomonas aeruginosa infection, to a similar extent as the efferocytosis promoter GAS6. Our findings provide a role of cochlin LCCL domain in the regulation of efferocytosis, alongside its already described pro-inflammatory role, as an immunomodulator for host response and homeostasis."

"abstract_text": "ID: 42520682\nTitle: Myeloid Piezo1 improves inflammation resolution and phagocytosis in acute liver injury.\nAbstract: Acetaminophen (APAP)-induced acute liver injury (AILI) is characterized by extensive cell death and sterile inflammation, with substantial accumulation of myeloid cells in necrotic areas. Macrophages are critical elements in acute hepatic inflammation and resolution. Piezo1 is a mechanically activated ion channel that modulates innate immune responses and senses microenvironmental cues. The functions of myeloid Piezo1 in AILI remain elusive. This study aimed to determine whether myeloid Piezo1 regulates inflammation resolution and macrophage-mediated clearance during AILI. To generate the AILI mouse model, APAP was administered intraperitoneally to Piezo1fl/fl and Piezo1\u0394LysM mice, and samples were collected at 6, 24, and 48\u00a0h after treatment. Bone marrow-derived macrophages (BMDMs) were stimulated with APAP-treated normal mouse liver cell line (AML12) supernatant to mimic sterile inflammatory response. Liver histology, immunostaining, gene expression analysis, flow cytometry, intracellular Ca2+ measurements, and phagocytosis/efferocytosis assays were performed. Piezo1 exerted protective effects against hepatotoxin-induced liver necrosis and promoted liver recovery after APAP overdose. In vitro assays revealed that Piezo1 alleviated the inflammatory response in bone marrow-derived macrophages. Mechanistically, myeloid Piezo1 manifested a more reparative phenotype and enhanced phagocytic activity by upregulating MerTK expression. Specifically, Piezo1 acted through Ca2+ influx to regulate the expression of MerTK at the target binding stage. Inhibition of MerTK induced more pro-inflammatory mediators and reduced phagocytic ability, phenocopying the Piezo1 deficiency. Separately, Piezo1 modulated cytoskeletal rearrangement via the FAK/Rac1 axis during target internalization. Pharmacological activation of Piezo1 promoted pro-resolution marker expression and enhanced efferocytosis/phagocytic clearance in vitro. This study identified myeloid Piezo1 as an important regulator of macrophage-mediated inflammation resolution and dying-cell clearance during AILI, providing a basis for future exploration of Piezo1-related pathways in macrophage-mediated liver recovery."

G protein-coupled receptor 146 (GPR146) has emerged as a pivotal regulator of systemic cholesterol metabolism; however, its role in the central nervous system and AD remains elusive. Here, we report that GPR146 deficiency in mice modulates ERK/PKA signaling without affecting baseline physiology or general behavior. Following intracerebroventricular (i.c.v.) injection of amyloid-\u03b2 (A\u03b2)42 oligomers, GPR146 was associated with altered A\u03b242-evoked ERK/PKA/Akt signaling both in vivo and in vitro. Mechanistically, Gpr146 ablation potentiated microglial A\u03b2 phagocytosis, which correlated with the transcriptional upregulation of phagocytic receptors, including TREM2, GPR34, P2Y6, and CR3, alongside increased expression of pro-inflammatory cytokines (TNF-\u03b1, IL-1\u03b2, IL-6). Moreover, GPR146 deficiency was linked to elevated levels of blood-brain barrier (BBB)-associated markers Cldn-5 and Glut-1 protein levels, while attenuating A\u03b2\u2011induced inflammatory responses in brain endothelial cells. At the metabolic level, GPR146 knockout modulated the expression of key enzymes governing glucose (GLUT1, GLUT3, G6PD, PFK, HK) and lipid (HMGCS1, ACACA, FASN, SCD1) metabolism and markedly reduced A\u03b2\u2011elicited lipid droplet accumulation in the cortex and hippocampus. Collectively, our findings establish GPR146 as a novel neurometabolic regulator whose deficiency correlates with enhanced A\u03b2 phagocytosis, maintenance of BBB-associated proteins, and altered cerebral metabolism, thereby presenting a potential therapeutic axis for early AD intervention."

Redirecting monocyte differentiation offers a compelling yet underexplored therapeutic opportunity. In this work, we found M1-polarized macrophage-derived extracellular vesicles (M1-EVs) efficiently induced monocytes to differentiate into anti-tumor macrophages via tumor necrosis factor alpha (TNF-\u03b1)-mediated signaling. Despite promising, the therapeutic efficacy of M1-EVs was constrained by insufficient glioma accumulation and CD47-mediated phagocytic inhibition. To address this challenge, we further engineered M1-EVs with dual-targeting specificity by genetically incorporating a tumor-directed chimeric antigen receptor (CAR) against IL13R\u03b12 or EGFRvIII together with CD47-blocking SIRP\u03b1 variants. The resulting dual-targeting EVs (M1-CS-EVs) exhibited enhanced blood-brain barrier (BBB) penetration and glioma accumulation while locally disrupting CD47-SIRP\u03b1 interactions. In three orthotopic glioma models, M1-CS-EVs elicited a potent anti-tumor immune response and enhanced tumor phagocytosis, significantly suppressing tumor growth while prolonging animal survival. Our findings establish a platform technology for directing monocyte differentiation toward anti-tumor phenotypes, offering a broadly applicable strategy for glioma treatment."

This neoplasm can present with different nonspecific symptoms, including fever, altered mental status, livedoid skin rashes, hepatosplenomegaly, and cytopenias, often complicating its diagnosis. The main categories are classical (formerly designated as Western), hemophagocytic variant (formerly designated as Asian), and primary cutaneous IVLBCL. A distinctly severe manifestation is hemophagocytic lymphohistiocytosis (HLH), a hyperinflammatory syndrome characterized by exaggerated immune activation and macrophage activation manifested by phagocytosis of hematopoietic cells including neutrophils, red blood cells, and platelets. We describe a 72-year-old female who presented with features reminiscent of an autoinflammatory syndrome including fever and hyperferritinemia followed by clinical features concerning for HLH. She developed a reticulated skin rash. Following skin biopsy, a diagnosis was rendered of IVLBCL complicated by HLH. The pathophysiology and other aspects of the literature pertaining to IVLBCL and HLH are reviewed."

We previously observed that in such comorbidity settings, macrophages exhibit impaired efferocytosis and reduced anti-inflammatory polarization. In this study, we investigated whether simultaneously restoring these two defective macrophage functions could provide a unified therapeutic strategy both for hepatic and vascular pathology. To establish a comorbidity model featuring concurrent hepatic steatosis and atherosclerosis, we fed ApoE-/-mice a high-fat diet for 14\u00a0weeks. Moreover, we engineered bone marrow-derived macrophages to co-overexpress TGF\u03b21 and MerTK (M\u03c6Smart), thereby restoring anti-inflammatory properties and phagocytic capacity, then treated mice with control macrophages or M\u03c6Smart. TGF\u03b21 and MerTK overexpression in macrophages reprogrammed these cells toward an anti-inflammatory phenotype and endowed them with strong phagocytic capacity under lipid-loaded conditions. M\u03c6Smart reprogrammed macrophage injection into ApoE-/- mice alleviated inflammation locally in the plaque and liver. Consistent with the reduced inflammation, plaques became smaller and more stable after the adoptive transfer of reprogrammed macrophages. Mechanistically, the reprogrammed macrophages alleviated disease manifestations not only via direct inhibition of plaque inflammation but also by reshaping the inflammatory condition in the liver and plaque, where the transferred M\u03c6Smart predominantly accumulated. Macrophage-targeted dual-gene therapy overcomes the limitations of single-target approaches and achieves simultaneous therapeutic efficacy both in the liver and vasculature, establishing a preclinical proof-of-concept for multi-gene synergistic cell therapy in cardiometabolic disease."

These microparticles induce a systemic hypercoagulable state that rapidly transitions into secondary coagulopathy and endotheliopathy. We hypothesize that removing these microparticles from circulation could mitigate the TBI-induced secondary pathologies and improve outcomes. In this study, we investigated the role of Gas-6 (growth arrest-specific 6) as a scavenging factor for microparticles. We quantified plasma Gas-6 levels in a mouse model of TBI and administered exogenous Gas-6 either before or after TBI to evaluate its effects on endotheliopathy, coagulopathy, and outcomes. Mechanistic studies assessed Gas-6-mediated clearance of circulating microparticles in TBI mice and investigated the molecular interactions by which Gas-6 binds microparticles and macrophages to facilitate microparticle scavenging. We found that plasma levels of Gas-6 were significantly reduced in mice subjected to severe TBI. Exogenous Gas-6 given either preinjury or postinjury attenuated coagulopathy, protected the integrity of the cerebral and pulmonary endothelium, improved neurological recovery, and increased overall survival of TBI mice. Gas-6 increased the clearance of anionic phospholipid-expressing microparticles from circulation by coupling microparticles with macrophages and monocytes through the \u03b3-carboxyglutamate and the LG1 (laminin G-like domain 1), respectively, to facilitate phagocytosis of microparticles in the liver. These findings demonstrate the therapeutic potential of Gas-6 for TBI and potentially for other acute pathologies, in which microparticles initiate and propagate coagulation dysfunction and endothelial injuries."

Here, we investigated macrophage sensing of Debaryomyces hansenii, a food-derived yeast that we found to be enriched within intestinal ulcers of Crohn disease (CD) patients. Using a cell surface receptor antibody screen of bone marrow-derived macrophages infected with a CD patient isolate of D. hansenii, we showed that D. hansenii-induced macrophage activation characterized by increased expression of co-stimulatory molecules, MHC-II, and pattern recognition receptors, including the C-type lectin receptor Dectin-1. Antibody blockade experiments showed both Dectin-1 and complement receptor 3 subunit CD11b were required for phagocytosis of D. hansenii, while Dectin-1 was uniquely required for production of the pro-inflammatory cytokine tumor necrosis factor (Tnf). CRISPR-Cas9-mediated deletion of Dectin-1 phenocopied antibody neutralization effects on phagocytosis. Furthermore, deletion of Dectin-1 or its downstream signaling adaptor molecule Card9 resulted in reduced Tnf secretion in response to D. hansenii. Dectin-1-mediated uptake of D. hansenii was observed in primary bone marrow-derived macrophage and dendritic cells, as well as across the spectrum of macrophage polarization states.

In a two-center cohort of patients undergoing total aortic arch replacement, we identify stress hyperglycemia as an independent determinant of poor postoperative outcomes that associates strongly with CD4+ T cell loss. Hyperglycemia induces inflammatory PANoptosis in CD4+ T cells from patients in response to surgical trauma. This results from elevated glucose driving the accumulation and release of succinate from monocytes, which subsequently acts on CD4+ T cells to compromise mitochondrial integrity and activate ZBP1-mediated PANoptosis. Our findings define a monocyte-T cell metabolic signaling axis that transduces hyperglycemic stress via elevated succinate to adaptive immune cell death and reveal potential therapeutic targets to prevent postoperative immune dysfunction and organ injury, especially for patients with hyperglycemic comorbidities."

Their functional plasticity is closely regulated by metabolic reprogramming, particularly glucose metabolism. Glucose-related pathways, including glycolysis, gluconeogenesis, the pentose phosphate pathway, glycogen metabolism, and pyruvate/lactate metabolism, influence TAM polarization, cytokine production, phagocytosis, antigen presentation, and T cell interactions. In many tumors, enhanced glycolysis and lactate accumulation promote M2-like TAM polarization and suppress CD8+ T cell activity, whereas certain metabolic programs may support M1-like anti-tumor functions under specific conditions. This mini review summarizes major glucose metabolic pathways involved in TAM regulation, highlights their context-dependent pro- and anti-tumor roles, and discusses therapeutic strategies for reprogramming TAM metabolism to improve anti-tumor immunity and immunotherapy response."

"abstract_text": "ID: 42564235\nTitle: Vagus nerve-driven microbiota homeostasis: a promising integrative add-on therapy for neurodevelopmental disorders.\nAbstract: Over the past two decades, the conceptualization of neurodevelopmental disorders (NDDs) has undergone a profound transformation, shifting from a primarily brain-centric framework toward a systems-level perspective that integrates peripheral physiological processes. Among these, the gut microbiota has emerged as a critical determinant of neurodevelopmental trajectories. Through its involvement in immune modulation, metabolic signaling, and neural communication, the microbiota-gut-brain axis (MGBA) exerts a pervasive influence on brain maturation and function. A growing body of evidence indicates that early-life disruptions of microbiota composition-commonly referred to as dysbiosis-are associated with an increased risk of NDDs, including autism spectrum disorder (ASD), attention-deficit/hyperactivity disorder (ADHD), and epilepsy. These disruptions are frequently driven by environmental exposures such as antibiotic use, cesarean delivery, dietary patterns, and psychosocial stress. Despite the expanding recognition of these associations, current therapeutic strategies aimed at restoring microbiota balance, including probiotics and fecal microbiota transplantation, have yielded inconsistent and often transient results. In this context, Vagus Nerve Stimulation (VNS), particularly in its non-invasive forms (nVNS), has emerged as a promising approach capable of modulating environmental exposures through the host-centered regulatory mechanisms of the MGBA. By influencing autonomic tone, activating the cholinergic anti-inflammatory pathway, and modulating neurotransmitter systems, nVNS may restore microbiota homeostasis while simultaneously improving neurodevelopmental outcomes. This article provides a comprehensive and integrative review of the mechanistic, preclinical, and clinical evidence supporting the role of nVNS as a microbiota-modulating intervention. We further discuss its potential as a safe, cost-effective and promising therapeutic strategy for neurodevelopmental disorders, with a particular emphasis on pediatric populations."

However, approximately half of the FTD patients are sporadic without a clear genetic background.

Here, we demonstrate that non-invasive and localizable pulsed electromagnetic fields (PEMFs) induce macrophage reprogramming downstream of transient receptor potential canonical 1 (TRPC1) channel activation. Brief (10\u00a0min) PEMF exposure polarized macrophages toward an M1 phenotype by activating Stimulator of Interferon Genes (STING)-dependent NF-\u03baB inflammatory pathways that were abolished by TRPC1 knockdown or inhibition. PEMF exposure directly enhanced the immunogenicity of breast cancer cells and modified macrophage-cancer crosstalk to promote M1 macrophage polarization and the attraction of STING-activated macrophages to the cancer cells. In co-cultures, PEMF exposure stimulated macrophage-mediated phagocytosis of cancer cells in a STING- and TRPC1-dependent manner. In spheroids, PEMFs induced the reprogramming of TAMs to an M1 status and selectively enhanced infiltration of M1 macrophages, resulting in STING-mediated phagocytosis of cancer cells. In mice, 2\u00a0weeks of twice-weekly PEMF exposure resorbed engrafted tumors and selectively eliminated cancer cells within tumors while promoting immune cell recruitment. PEMFs offer a non-invasive manner to locally reprogram TAMs within the tumor microenvironment to preferentially eliminate cancer cells."

Reduced NLRC5 expression is associated with a poor prognosis for many types of cancers. Previously, we showed that mice with a myeloid-specific deletion of Nlrc5 (Nlrc5m\u00f8-KO) develop gastric lymphoid lesions to Helicobacter infection resembling early-stage marginal zone lymphoma. We hypothesized that NLRC5 deficiency may promote a tumor-permissive microenvironment mediated by tumor-associated macrophages (TAMs). Consistent with this hypothesis, splenic macrophages from Helicobacter-infected Nlrc5m\u00f8-KO mice had upregulated expression of genes encoding the TAM receptor tyrosine kinases, Axl and Mertk. The levels of AXL and MERTK gene expression and MERTK phosphorylation were increased in NLRC5-/- THP-1 macrophages when compared with WT cells. In response to Helicobacter stimulation, Nlrc5-/- macrophages had significantly elevated anti-inflammatory responses (IL-10, TGF-\u03b2, Socs1, Socs3) compared with WT cells. Importantly, Nlrc5-/-macrophages showed enhanced efferocytosis and reduced antigen presentation to CD8+ T cells. Pretreatment of macrophages with AXL and MERTK inhibitors (R428, UNC2025) resulted in reduced efferocytosis and phosphorylation of downstream signaling molecules, STAT3 and ERK1/2. We propose that defective NLRC5 signaling in macrophages leads to tumor-permissive responses, thereby promoting the development of gastric lymphoid neogenesis to Helicobacter infection."

Model stability and performance were assessed by 5-fold stratified cross-validation and independent test validation. The 45 principal components accounted for 99.92% of cumulative variance. LR showed optimal performance, with a test AUC of 0.9821, classification accuracy of 84.62%, and a mean cross-validation AUC of 0.9606 (95% CI: 0.8887-0.9895).

IL-33 is an alarmin that initiates type 2 immune responses, including increased production of IL-13, which promotes MerTK expression. The ability of IL-33 to promote efferocytosis in vivo was examined. Intraperitoneal administration of IL-33 to mice increased local MerTK+ macrophage numbers within 48h. MerTK+ macrophages were not similarly induced by free mitochondria, an alternative cell damage associated signal. Efferocytotic activity was increased rapidly in response to apoptotic thymocytes in IL-33-treated mice. The established inducer of MerTK expression, IL-13, was detected in peritoneal lavage fluid shortly after IL-33 administration. Peritoneal eosinophils expressed the IL-33 receptor and demonstrated both intracellular IL-13 by flow cytometry and significantly increased Il13 transcript expression following IL-33 treatment. In contrast, neither elevated IL-13 expression nor IL-13 protein secretion was observed in peritoneal lymphocyte populations within the first 6 hours after IL-33 administration. Primary cultures of bone marrow-derived mouse mast cells and eosinophils demonstrated IL-13 protein responses to IL-33 administration within 6\u00a0h. Mast cell-deficient Cpa3-Cre; Mcl-1fl/fl mice had significantly reduced IL-13 levels in the peritoneal cavity 3 hours after IL-33 administration when compared with mast cell-containing littermates.

These findings contribute to our understanding of clinical situations where elevated soluble IL-33 receptor (sST2) and/or lower mast cell numbers are associated with worse clinical outcome."

G protein-coupled receptor 146 (GPR146) has emerged as a pivotal regulator of systemic cholesterol metabolism; however, its role in the central nervous system and AD remains elusive. Here, we report that GPR146 deficiency in mice modulates ERK/PKA signaling without affecting baseline physiology or general behavior. Following intracerebroventricular (i.c.v.) injection of amyloid-\u03b2 (A\u03b2)42 oligomers, GPR146 was associated with altered A\u03b242-evoked ERK/PKA/Akt signaling both in vivo and in vitro. Mechanistically, Gpr146 ablation potentiated microglial A\u03b2 phagocytosis, which correlated with the transcriptional upregulation of phagocytic receptors, including TREM2, GPR34, P2Y6, and CR3, alongside increased expression of pro-inflammatory cytokines (TNF-\u03b1, IL-1\u03b2, IL-6). Moreover, GPR146 deficiency was linked to elevated levels of blood-brain barrier (BBB)-associated markers Cldn-5 and Glut-1 protein levels, while attenuating A\u03b2\u2011induced inflammatory responses in brain endothelial cells. At the metabolic level, GPR146 knockout modulated the expression of key enzymes governing glucose (GLUT1, GLUT3, G6PD, PFK, HK) and lipid (HMGCS1, ACACA, FASN, SCD1) metabolism and markedly reduced A\u03b2\u2011elicited lipid droplet accumulation in the cortex and hippocampus. Collectively, our findings establish GPR146 as a novel neurometabolic regulator whose deficiency correlates with enhanced A\u03b2 phagocytosis, maintenance of BBB-associated proteins, and altered cerebral metabolism, thereby presenting a potential therapeutic axis for early AD intervention."

This neoplasm can present with different nonspecific symptoms, including fever, altered mental status, livedoid skin rashes, hepatosplenomegaly, and cytopenias, often complicating its diagnosis. The main categories are classical (formerly designated as Western), hemophagocytic variant (formerly designated as Asian), and primary cutaneous IVLBCL. A distinctly severe manifestation is hemophagocytic lymphohistiocytosis (HLH), a hyperinflammatory syndrome characterized by exaggerated immune activation and macrophage activation manifested by phagocytosis of hematopoietic cells including neutrophils, red blood cells, and platelets. We describe a 72-year-old female who presented with features reminiscent of an autoinflammatory syndrome including fever and hyperferritinemia followed by clinical features concerning for HLH. She developed a reticulated skin rash. Following skin biopsy, a diagnosis was rendered of IVLBCL complicated by HLH. The pathophysiology and other aspects of the literature pertaining to IVLBCL and HLH are reviewed."

We previously observed that in such comorbidity settings, macrophages exhibit impaired efferocytosis and reduced anti-inflammatory polarization. In this study, we investigated whether simultaneously restoring these two defective macrophage functions could provide a unified therapeutic strategy both for hepatic and vascular pathology. To establish a comorbidity model featuring concurrent hepatic steatosis and atherosclerosis, we fed ApoE-/-mice a high-fat diet for 14\u00a0weeks. Moreover, we engineered bone marrow-derived macrophages to co-overexpress TGF\u03b21 and MerTK (M\u03c6Smart), thereby restoring anti-inflammatory properties and phagocytic capacity, then treated mice with control macrophages or M\u03c6Smart. TGF\u03b21 and MerTK overexpression in macrophages reprogrammed these cells toward an anti-inflammatory phenotype and endowed them with strong phagocytic capacity under lipid-loaded conditions. M\u03c6Smart reprogrammed macrophage injection into ApoE-/- mice alleviated inflammation locally in the plaque and liver. Consistent with the reduced inflammation, plaques became smaller and more stable after the adoptive transfer of reprogrammed macrophages. Mechanistically, the reprogrammed macrophages alleviated disease manifestations not only via direct inhibition of plaque inflammation but also by reshaping the inflammatory condition in the liver and plaque, where the transferred M\u03c6Smart predominantly accumulated. Macrophage-targeted dual-gene therapy overcomes the limitations of single-target approaches and achieves simultaneous therapeutic efficacy both in the liver and vasculature, establishing a preclinical proof-of-concept for multi-gene synergistic cell therapy in cardiometabolic disease."

Here, we investigated macrophage sensing of Debaryomyces hansenii, a food-derived yeast that we found to be enriched within intestinal ulcers of Crohn disease (CD) patients. Using a cell surface receptor antibody screen of bone marrow-derived macrophages infected with a CD patient isolate of D. hansenii, we showed that D. hansenii-induced macrophage activation characterized by increased expression of co-stimulatory molecules, MHC-II, and pattern recognition receptors, including the C-type lectin receptor Dectin-1. Antibody blockade experiments showed both Dectin-1 and complement receptor 3 subunit CD11b were required for phagocytosis of D. hansenii, while Dectin-1 was uniquely required for production of the pro-inflammatory cytokine tumor necrosis factor (Tnf). CRISPR-Cas9-mediated deletion of Dectin-1 phenocopied antibody neutralization effects on phagocytosis. Furthermore, deletion of Dectin-1 or its downstream signaling adaptor molecule Card9 resulted in reduced Tnf secretion in response to D. hansenii. Dectin-1-mediated uptake of D. hansenii was observed in primary bone marrow-derived macrophage and dendritic cells, as well as across the spectrum of macrophage polarization states. Together, these findings define the role of Dectin-1-Card9 signaling axis in innate immune cell sensing of D. hansenii. These findings support the emerging relevance of innate immune recognition of a yeast in Crohn disease pathogenesis."

Glucose-related pathways, including glycolysis, gluconeogenesis, the pentose phosphate pathway, glycogen metabolism, and pyruvate/lactate metabolism, influence TAM polarization, cytokine production, phagocytosis, antigen presentation, and T cell interactions. In many tumors, enhanced glycolysis and lactate accumulation promote M2-like TAM polarization and suppress CD8+ T cell activity, whereas certain metabolic programs may support M1-like anti-tumor functions under specific conditions. This mini review summarizes major glucose metabolic pathways involved in TAM regulation, highlights their context-dependent pro- and anti-tumor roles, and discusses therapeutic strategies for reprogramming TAM metabolism to improve anti-tumor immunity and immunotherapy response."

However, approximately half of the FTD patients are sporadic without a clear genetic background. To compare characteristics of microglia from different FTD subtypes, we generated induced pluripotent stem cell-derived microglia (iMG) from sporadic and C9-HRE-carrying behavioral variant FTD (bvFTD) patients and healthy controls. C9-HRE iMG displayed C9-HRE-associated RNA foci and dipeptide repeat proteins. All bvFTD iMG had fewer LAMP2-A-positive vesicles compared to control iMG. Additionally, C9-HRE iMG showed significantly increased LC3BII/I conversion after bafilomycin A1 treatment and altered phagocytic activity. The gene expression profile of C9-HRE iMG only modestly differed from the control iMG, but was greatly different from the sporadic bvFTD patient iMG.

Here, we demonstrate that non-invasive and localizable pulsed electromagnetic fields (PEMFs) induce macrophage reprogramming downstream of transient receptor potential canonical 1 (TRPC1) channel activation. Brief (10\u00a0min) PEMF exposure polarized macrophages toward an M1 phenotype by activating Stimulator of Interferon Genes (STING)-dependent NF-\u03baB inflammatory pathways that were abolished by TRPC1 knockdown or inhibition. PEMF exposure directly enhanced the immunogenicity of breast cancer cells and modified macrophage-cancer crosstalk to promote M1 macrophage polarization and the attraction of STING-activated macrophages to the cancer cells. In co-cultures, PEMF exposure stimulated macrophage-mediated phagocytosis of cancer cells in a STING- and TRPC1-dependent manner. In spheroids, PEMFs induced the reprogramming of TAMs to an M1 status and selectively enhanced infiltration of M1 macrophages, resulting in STING-mediated phagocytosis of cancer cells. In mice, 2\u00a0weeks of twice-weekly PEMF exposure resorbed engrafted tumors and selectively eliminated cancer cells within tumors while promoting immune cell recruitment. PEMFs offer a non-invasive manner to locally reprogram TAMs within the tumor microenvironment to preferentially eliminate cancer cells."

Reduced NLRC5 expression is associated with a poor prognosis for many types of cancers. Previously, we showed that mice with a myeloid-specific deletion of Nlrc5 (Nlrc5m\u00f8-KO) develop gastric lymphoid lesions to Helicobacter infection resembling early-stage marginal zone lymphoma. We hypothesized that NLRC5 deficiency may promote a tumor-permissive microenvironment mediated by tumor-associated macrophages (TAMs). Consistent with this hypothesis, splenic macrophages from Helicobacter-infected Nlrc5m\u00f8-KO mice had upregulated expression of genes encoding the TAM receptor tyrosine kinases, Axl and Mertk. The levels of AXL and MERTK gene expression and MERTK phosphorylation were increased in NLRC5-/- THP-1 macrophages when compared with WT cells. In response to Helicobacter stimulation, Nlrc5-/- macrophages had significantly elevated anti-inflammatory responses (IL-10, TGF-\u03b2, Socs1, Socs3) compared with WT cells. Importantly, Nlrc5-/-macrophages showed enhanced efferocytosis and reduced antigen presentation to CD8+ T cells. Pretreatment of macrophages with AXL and MERTK inhibitors (R428, UNC2025) resulted in reduced efferocytosis and phosphorylation of downstream signaling molecules, STAT3 and ERK1/2. We propose that defective NLRC5 signaling in macrophages leads to tumor-permissive responses, thereby promoting the development of gastric lymphoid neogenesis to Helicobacter infection."

After radiomic feature extraction, the cohort was divided into a training set (n=59) and an independent test set (n=26) at a 7:3 ratio via stratified sampling. Data were processed with Z-score normalization, variance thresholding and PCA (45 principal components). Five classifiers were constructed: LR, linear SVM, RF, XGBoost and LightGBM. Model stability and performance were assessed by 5-fold stratified cross-validation and independent test validation. The 45 principal components accounted for 99.92% of cumulative variance. LR showed optimal performance, with a test AUC of 0.9821, classification accuracy of 84.62%, and a mean cross-validation AUC of 0.9606 (95% CI: 0.8887-0.9895).

The model's decision relied on key texture features; only GLSZM non-uniformity differed significantly between groups, consistent with their pathophysiological characteristics. The PCA-reduced and regularization-optimized LR model has excellent generalization, stability and clinical interpretability in differentiating pulmonary metastases from breast and colorectal cancers. This study preliminarily highlights the potential of LR in high-dimensional small-sample scenarios, and provides a foundational methodological reference for future large-scale multicenter diagnostic research."

These localized microenvironments are shaped by factors such as nutrient availability, hypoxia, acidosis, and immunomodulatory metabolites, all of which strongly influence CD8\u207a T cell infiltration, migration, persistence, and effector function. Growing evidence indicates that spatial metabolic heterogeneity contributes to immune exclusion, T cell dysfunction, and resistance to immunotherapy. This has been accompanied by major advances in spatial metabolomics, particularly mass spectrometry imaging, which now enable the in situ mapping of metabolites within intact tissues. Combined with transcriptomic, proteomic, and imaging-based approaches, these technologies provide unprecedented insight into how metabolism is organized across tumors and how it shapes tumor-immune interactions. In this review, we discuss how metabolic zonation shapes CD8\u207a T cell function across primary tumors and metastatic lesions. We highlight emerging evidence linking localized metabolic programs to T cell exhaustion, impaired motility, and altered immune composition, and discuss therapeutic strategies aimed at improving T cell metabolic fitness, including metabolic modulation and engineering approaches relevant to immune checkpoint blockade and adoptive cell therapies. Finally, we consider the translational potential of spatial metabolomics for biomarker discovery and the development of precision immunometabolic oncology."

Free-text MRI reports may describe the primary tumor but may inconsistently document key management-relevant findings, including mesorectal fascia and circumferential resection margin status, depth of extramural spread, extramural vascular invasion, lateral pelvic lymph nodes, and low rectal sphincter complex involvement. This retrospective audit assessed whether use of a structured MRI reporting template was associated with improved completeness of primary rectal cancer staging reports. This retrospective audit included 60 pelvic MRI reports performed for suspected or biopsy-proven primary rectal carcinoma at a tertiary care radiology department. Thirty consecutive reports prepared before template implementation were assigned to the free-text reporting group, and 30 reports prepared after template implementation were assigned to the structured reporting group. Reports were assessed using a predefined checklist of essential MRI staging elements, including tumor location, distance from the anal verge, craniocaudal tumor length, circumferential tumor position, relationship to the anorectal junction and anterior peritoneal reflection, MRI T category, depth of extramural spread, mesorectal fascia/circumferential resection margin status, extramural vascular invasion, mesorectal nodes, tumor deposits, lateral pelvic lymph nodes, sphincter complex involvement, levator ani involvement, adjacent organ invasion, and final MRI-based risk summary.

No formal statistical hypothesis testing was performed; therefore, these findings should be interpreted descriptively rather than inferentially. Implementation of a structured MRI reporting template was associated with higher report completeness in this descriptive retrospective audit of primary rectal cancer staging reports. The structured template was associated with more complete documentation of clinically relevant reporting elements, particularly margin status, extramural spread, extramural vascular invasion, lateral pelvic nodes, and low rectal sphincter complex involvement. However, report completeness was the only measured outcome, and no formal statistical testing was performed. Further studies with statistical testing, reviewer blinding, and assessment of diagnostic accuracy or clinical outcomes are needed."

For decades, treatment was limited to lifestyle interventions. The years 2024 and 2025 marked a paradigm shift with the first-ever FDA approvals of pharmacologic agents for MASH. This comprehensive narrative review synthesizes the evidence for newly approved and emerging pharmacotherapies for MASH, addressing the mechanisms of action, pivotal clinical trial data, efficacy, safety profiles, and place in therapy for resmetirom and semaglutide. It also discusses key agents including pioglitazone, saroglitazar, and vitamin E, and evaluates the non-invasive testing (NIT) toolkit-including FIB-4, VCTE, shear wave elastography, MRE, and ELF-in the context of a structured, risk-stratified clinical algorithm. Resmetirom (Rezdiffra), a THR-\u03b2 agonist, achieved MASH resolution in 26%-30% versus 10% placebo and fibrosis improvement in 24%-26% versus 14% placebo at 52 weeks in the MAESTRO-NASH trial. Semaglutide 2.4 mg (Wegovy) demonstrated a 28.7% delta over placebo in MASH resolution in the ESSENCE trial. Pioglitazone has additional evidence for reducing the FIB-4 index in real-world studies. Saroglitazar, a PPAR-\u03b1/\u03b3 dual agonist approved in India, has shown significant reductions in ALT, liver fat, and metabolic parameters in Phase 2 studies and is advancing to Phase 2b. Shear wave elastography is a clinically important alternative to VCTE for fibrosis staging, particularly in patients with obesity, and offers value in resolving discordant FIB-4/VCTE results. The approval of resmetirom and semaglutide marks a new era in MASH management. A risk-stratified algorithmic approach using NITs guides patient selection, with liver biopsy reserved for specific clinical scenarios.

Here, we present a ULM-guided model-based reconstruction framework, termed 3D-PAULMprior that incorporates sub-diffraction vascular priors from concurrent ultrasound localization microscopy (ULM) into 3D photoacoustic reconstruction. The method uses weighted regional Laplacian regularization to integrate high-resolution vascular information into the inverse problem, thereby enhancing vascular sharpness, suppressing limited-view artifacts, and improving blood oxygen saturation estimation. We validated 3D-PAULMprior using numerical simulations, tissue-mimicking phantoms, and in vivo mouse brain imaging.

In vivo, 3D-PAULMprior enhanced the delineation of the vascular structures that were poorly resolved in conventional reconstructions and produced more spatially confined sO\u2082 maps.

These artifacts interact synergistically, leading to severe image degradation that conventional correction methods fail to\u00a0address. We propose a multi-stage deep learning framework, HD-TMAR, to systematically decompose and correct combined truncation and metal artifacts in HD CBCT. The proposed framework adopts a multi-stage restoration strategy comprising three stages: (1) Sinogram Correction, which explicitly isolates the artifact residuals from the projection data and synergizes them with structural prior-normalized features to systematically suppress global truncation biases and metal artifacts; (2) Merging and Reconstruction, which employs a specialized overlapping patching and selective replacement strategy to accurately reconstruct the truncated regions and metal traces; and (3) Image Refinement, where ImgNet further enhances the reconstructed image to restore fine anatomical\u00a0textures. Experiments using realistic simulation datasets demonstrated that the proposed method achieved the highest qualitative fidelity and quantitative metrics compared to previous deep learning MAR methods.

Consistently upregulated Piezo1 expression in cardiac macrophages and MoMs post-MI is found. Elevated Piezo1 expression in MoMs directly contributes to increased Piezo1 levels in cardiac macrophages. Myeloid cell-specific Piezo1-deficient mice (Piezo1Lyz2) exhibit significant improvements in ventricular function/remodeling after MI, accompanied by decreased apoptotic cardiomyocytes and decreased inflammation, increased numbers of macrophages, and increased border zone efferocytosis. In vitro, Piezo1 activation by Yoda1 increased oxygen-glucose deprivation (OGD)-induced ferroptosis and impaired MoM efferocytosis. Conversely, Piezo1 deficiency in MoMs decreases ferroptosis and increases efferocytosis. SLC7A11 is shown to mediate Piezo1-induced defective efferocytosis in MoMs. Piezo1 activation aggravated OGD-induced macrophage ferroptosis via Ca2+ influx followed by SLC15A3 upregulation. Piezo1 upregulated SLC7A11 in macrophages via a Ca2+/ATF4-dependent pathway. MoM-specific SLC7A11 knockdown significantly increases efferocytosis, reduces cardiomyocyte apoptosis and inflammation, and ameliorates post-MI left ventricular remodeling and function. In conclusion, early Piezo1 activation in MoMs is identified during MI, which governs the fate and function of recruited macrophages. These data establish an ischemic heart-bone marrow functional network and provide a novel therapeutic strategy in which MoM Piezo1 is targeted for post-MI heart repair."

Consistently upregulated Piezo1 expression in cardiac macrophages and MoMs post-MI is found. Elevated Piezo1 expression in MoMs directly contributes to increased Piezo1 levels in cardiac macrophages. Myeloid cell-specific Piezo1-deficient mice (Piezo1Lyz2) exhibit significant improvements in ventricular function/remodeling after MI, accompanied by decreased apoptotic cardiomyocytes and decreased inflammation, increased numbers of macrophages, and increased border zone efferocytosis. In vitro, Piezo1 activation by Yoda1 increased oxygen-glucose deprivation (OGD)-induced ferroptosis and impaired MoM efferocytosis. Conversely, Piezo1 deficiency in MoMs decreases ferroptosis and increases efferocytosis. SLC7A11 is shown to mediate Piezo1-induced defective efferocytosis in MoMs. Piezo1 activation aggravated OGD-induced macrophage ferroptosis via Ca2+ influx followed by SLC15A3 upregulation. Piezo1 upregulated SLC7A11 in macrophages via a Ca2+/ATF4-dependent pathway. MoM-specific SLC7A11 knockdown significantly increases efferocytosis, reduces cardiomyocyte apoptosis and inflammation, and ameliorates post-MI left ventricular remodeling and function. In conclusion, early Piezo1 activation in MoMs is identified during MI, which governs the fate and function of recruited macrophages. These data establish an ischemic heart-bone marrow functional network and provide a novel therapeutic strategy in which MoM Piezo1 is targeted for post-MI heart repair."

Currently, there are few approved clinical therapies that specifically target white matter repair to enhance functional recovery after stroke. We demonstrated that microglial adenosine 2A receptor (A2AR) is essential for spontaneous white matter regeneration after ischemic injury in mice. Deletion of A2AR in microglia specifically impaired chronic-phase repair without altering the severity of acute ischemic injury. Pharmacological activation of A2AR signaling with blood-brain barrier-permeable agonistic micelles during the early reperfusion phase enhanced white matter structural repair and led to sustained improvements in cognitive and sensorimotor function in mice. Mechanistically, A2AR activation promoted microglial efferocytosis of apoptotic cells and myelin debris in the lesioned white matter, thereby limiting secondary necrosis-induced inflammation, enhancing neurotrophic factor release, and establishing a reparative microenvironment conducive to oligodendrocyte precursor cell differentiation and remyelination. Moreover, A2AR signaling engaged HIF1\u03b1-dependent metabolic reprogramming to increase glycolysis, thereby providing the energetic support required for efficient and sustained efferocytosis. Together, these findings identify A2AR as a critical regulator of microglia-mediated white matter repair and a promising therapeutic target for enhancing regeneration after stroke."

Here, we found that the mechanosensitive ion channel Piezo1 was up-regulated in hepatic fibrosis. Macrophages lacking Piezo1 showed sustained inflammation and impaired spontaneous resolution of early liver fibrosis. Further analysis revealed an impairment of clearance of apoptotic cells by macrophages in the fibrotic liver. Macrophages showed enhanced efferocytosis when cultured on rigid substrates but not soft ones, suggesting stiffness-dependent efferocytosis of macrophages required Piezo1 activation. Besides, Piezo1 was involved in the efficient acidification of the engulfed cargo in the phagolysosomes and affected the subsequent expression of anti-inflammation genes after efferocytosis. Pharmacological activation of Piezo1 increased the efferocytosis capacity of macrophages and accelerated the resolution of inflammation and fibrosis.

However, concurrent immunosuppression may compromise vaccine efficacy. This study investigated the effect of immunosuppression induced by either chicken anaemia virus (CAV) or infectious bursal disease virus (IBDV), administered prior to or following vaccination with the M. gallisepticum live vaccine strain ts-304 (Vaxsafe MG304), on tracheal host responses to subsequent challenge with virulent M. gallisepticum. Tracheal responses were assessed by genome-wide transcriptional profiling in these groups and compared across unvaccinated-unchallenged, unvaccinated-challenged, vaccinated-unchallenged and vaccinated-challenged groups that had not been exposed to CAV or IBDV. Immunosuppression resulted in significant differences in tracheal transcriptional responses compared to immunocompetent groups, irrespective of the timing of infection with CAV or IBDV. Differences in transcription were more pronounced in the IBDV-infected groups than the CAV-infected groups. Functional interrogation of differentially transcribed genes revealed adverse effects of M. gallisepticum on extracellular and intracellular signalling, cell communication, cellular actin dynamics, formation of the cellular cytoskeleton, and cellular metabolic pathways in the tracheal mucosa of immunosuppressed groups. In addition, there were indications of down-regulation of both innate and adaptive immune responses, including cytokine signalling, antigen processing presentation, and immune cell receptor signalling in the immunosuppressed groups. Specifically, findings indicated that infection with CAV impaired pro-inflammatory and adaptive T-cell responses in the tracheal mucosa. The findings implied that the primary immune response induced post-vaccination and the secondary immune response induced post-challenge with virulent M. gallisepticum were both affected by infection with these two viruses. Coupled with previous observations of reduced antibody titres against M. gallisepticum, and increased rates of recovery of virulent M. gallisepticum in both CAV- and IBDV-infected groups, the significant transcriptional changes detected in the current study highlighted the roles of both cell-mediated (CMI) and humoral immunity (HI) in vaccine-induced protection, as CAV mainly affects CMI and IBDV mainly affects HI. These findings will assist in identifying the mechanisms underlying the reduced efficacy of live attenuated mycoplasma vaccines in immunosuppressed animals."

Class I myosins Myo1e and Myo1f (Myo1e/f) have been implicated in linking the plasma membrane to the actin network, but their specific roles during Fc-receptor-mediated phagocytosis remain unclear. Using CRISPR-edited RAW 264.7 macrophages lacking Myo1e and Myo1f, we show that double knockout (dKO) cells exhibit markedly reduced uptake of IgG-coated beads, a phenotype that is partially rescued by re-expression of either myosin. Lattice-light-sheet and confocal imaging revealed distinct F-actin architectures corresponding to the various stages of cup progression, including basal podosome-like adhesions, individual phagocytic podosomes (actin teeth) along the rim of the cup, and a contractile phagocytic ring formed by the reorganization of podosomes into a higher-order network. In Myo1e/f-deficient cells, podosome formation was diminished, actin teeth were largely absent, and the phagocytic ring formed prematurely, which was often accompanied by stalled cup progression and repeated engulfment attempts. Myo1e/f localized both to podosomes and to the inner surface of the phagocytic ring, non-muscle myosin II (NM2) localized to the outer surface, and the absence of Myo1e/f correlated with the diffuse distribution of NM2. In addition, Myo1e/f-deficient macrophages exhibited increased trogocytosis of antibody-opsonized HL-60 cells, indicating a shift from whole-target engulfment toward partial target ingestion. These results suggest that Myo1e/f coordinate spatial and temporal transitions between protrusive and contractile actin networks, thereby ensuring efficient phagocytic cup progression. Our findings highlight a dual role for Myo1e/f in adhesion regulation and force balance during macrophage phagocytosis."

"abstract_text": "ID: 40741709\nTitle: Depletion of endomembrane reservoirs drives phagocytic appetite exhaustion in macrophages.\nAbstract: During phagocytosis, a phagocytic cup grows via F-actin remodeling and localized secretion to entrap a particle within a phagosome, which then fuses with endosomes and lysosomes to digest the particle, followed by phagosome resolution. As spatially limited systems, phagocytes have a maximal phagocytic capacity, at which point further uptake must be reduced. However, the processes responsible for phagocytic appetite exhaustion as phagocytes reach their maximal phagocytic capacity are poorly defined. We found that macrophages at their capacity have lower surface levels of Fc\u03b3 receptors but overexpression of these receptors did not increase their capacity, suggesting that receptor levels are not limiting. We found that surface membrane in-folding, membrane tension and cortical F-actin were all reduced in exhausted macrophages. Although this might contribute to appetite suppression, we also found that 'free' endosomes and lysosomes were severely depleted in exhausted macrophages. Consequently, focal exocytosis at sites of externally bound particles was reduced. In comparison, macrophages recovered their appetite if phagosome resolution was permitted. We propose that depletion of the endomembrane pools is a major determinant of phagocytic fatigue as macrophages reach their phagocytic capacity."

During phagocytosis, macrophages internalize and degrade pathogens and apoptotic cells by forming the phagocytic cup and phagosome. Osteoclasts resorb bone by forming the sealing zone and ruffled border at the ventral membrane. This review explores the organizational principles of these dynamic structures. In in vitro frustrated phagocytosis, specifically 2D phagocytosis by macrophages, the activation of the Fc\u03b3 receptor generates multiple self-organized waves containing F-actin, Arp2/3, and phosphoinositides. The propagation of these circular actin waves segregates the inside from the outside, leading to the compartmentalization of the ventral membrane. As the actin wave passes, cortical actin is disrupted, and membrane remodeling occurs within the wave, creating a new membrane domain with high exocytic activity. These processes mirror the formation of the constriction zone in the phagocytic cup and phagosome during 3D phagocytosis. A similar mechanism may also contribute to the formation of the sealing zone and ruffled border in osteoclasts. Based on these observations, we propose that dynamic structures formed from actin waves are organized through the fractal integration of self-organized, oscillatory substructures, with F-actin treadmilling fueling their formation and maintenance."

While a number of mathematical models have been developed to describe this process, they often overlook membrane tension, a key physical parameter known to influence membrane deformation and cytoskeletal behaviour. To address this gap, we present an enhanced mathematical model of receptor motion during phagocytosis that explicitly incorporates the role of membrane tension. Further, we introduce a signalling component that is coupled to receptor dynamics via the membrane tension. We find that including tension results in fundamentally different engulfment behaviour, which is slower than that predicted by models without tension. In particular, unlike in the previous version of this model, we show that tension can lead to stalled engulfment, an experimentally-observed phenomenon known as frustrated phagocytosis. We also find that signalling is able to modify engulfment behaviour, especially at later stages, and is able to alter cup growth to become linear in time without the need for receptor drift as introduced in previous models. These findings offer new insights into the role of membrane tension and biophysical regulation in phagocytosis, with implications for immune function, cell motility and targeted drug delivery."

The degradation process was generally believed to occur only after phagosome internalization and maturation. Here, we report an early DNase activity at the nascent phagocytic cup (PC) prior to its closure. Using a fluorescent DNase sensor, we revealed rapid and ubiquitous DNase activity upon PC formation across various macrophage types. We further identified the responsible enzyme as the membrane-bound DNaseX, which is constitutively recruited to the PC during PC formation. Although F-actin polymerization is dispensable for DNaseX recruitment, it is essential for its enzymatic activity, likely by promoting physical engagement of DNaseX with solid DNA materials. Functionally, we show that macrophages degrade extracellular DNA (eDNA) within bacterial biofilms through direct physical contact, clearing the eDNA structures without internalization. These findings reveal a previously unrecognized DNA degradation mechanism operating at the macrophage membrane, suitable for degrading bulky eDNA materials which cannot be directly internalized by macrophages."

Syk owns two SH2 domains that interact with biphosphorylated ITAMs of the Fc\u03b3R upon phagocytosis. This results in the activation of Syk by autophosphorylation, triggering phosphorylation of several downstream targets, F-actin polymerization, and phagocytosis of the IgG-opsonized target. We found that Syk is S-acylated upon phagocytosis by macrophages. Palmitoylation is performed on a single Syk-Cys by the DHHC5 enzyme that specifically associates with Syk upon phagocytosis. Syk palmitoylation is important for Syk localization to the phagocytic cup, phosphorylation, and phagocytosis. We observed that another Syk-Cys residue, within a redox motif, is modified by sulfenylation. Nevertheless, Syk desulfenylation seems to occur during phagocytosis, when H2O2 production at the cup decreases, after 3.5 min of phagocytosis. Molecular dynamics studies indicated that desulfenylation increased the exposure of a loop within the Syk interdomain B. This could facilitate phosphorylation of key Syk-Tyr residues by upstream kinases. We thus propose an updated model for Syk activation during Fc\u03b3R-mediated phagocytosis that involves both Syk palmitoylation and desulfenylation."

Whereas stiff cargos elicited canonical phagocytic cup formation and rapid engulfment, soft cargos induced an architecturally distinct response, characterized by filamentous actin protrusions at the center of the contact site, slower cup advancement, and frequent phagocytic stalling. Using phosphoproteomics, we identified \u03b22 integrins as critical mediators of this mechanically regulated phagocytic switch. Macrophages lacking \u03b22 integrins or their downstream effectors, Talin1 and Vinculin, exhibited specific defects in phagocytic cup architecture and selective suppression of stiff cargo uptake. We conclude that integrin signaling serves as a mechanical checkpoint during phagocytosis to pair cargo rigidity to the appropriate mode of engulfment."

"abstract_text": "ID: 41071099\nTitle: Mechanosensitive ion channels as novel targets in osteoporosis.\nAbstract: Osteoporosis is the most prevalent metabolic bone disease globally, leading to an increased risk of fractures. Recent advances in ion channel research have shed light on the importance of mechanosensitive ion channels as novel players in these pathophysiological processes. This perspective discusses the involvement of the mechanosensitive ion channels TREK-1, Piezo, and volume-regulated anion channels (VRACs) as potential novel pharmacological targets for the treatment of osteoporosis. TREK-1, a mechanosensitive K2P channel is important for maintaining the resting membrane potential in many cells, including osteoblasts and osteoclasts. K2P channels regulate osteoblast proliferation and differentiation, as well as osteoclast activity, potentially modulating bone remodeling in osteoporosis. Piezo channels influence osteoblast differentiation and osteoclast activity by modulating calcium influx, which is crucial for osteogenic signaling pathways, such as Wnt/\u03b2-catenin and ERK1/2. Piezo1 activation promotes bone formation, while its deficiency leads to impaired osteogenesis and increased bone resorption. Volume-regulated anion channels have been shown to be involved in osteoblast adaptation to mechanical stress and macrophage polarization, which indicates their importance for bone homeostasis. Chronic inflammation is a major contributor to osteoporosis progression. Evidence of ion channel involvement in this process has emerged in recent years. Specifically, macrophage function in osteoporosis seems to be linked to ion channel activity. Inflammatory polarization of macrophages is a key player in inflammation-induced bone loss and can be driven by mechanosensitive ion channels. Modulating these ion channels may provide new therapeutic opportunities. Given the complexity of ion channel interactions in bone cells and their regulatory role in bone remodeling, understanding their precise function in osteoporosis is essential. Targeted modulation of mechanosensitive ion channels holds promise as a novel therapeutic approach to mitigate inflammation-driven bone loss and improve bone density. Further research into their role in osteoclasts and macrophage-driven bone degradation will aid in developing innovative osteoporosis treatments. Osteoporosis is the most common bone disease worldwide. The exact reasons for why bones weaken is often not fully understood, which makes the development of targeted therapies difficult. Our article highlights a new perspective: certain proteins in bone cells, called mechanosensitive ion channels, may be key players in osteoporosis. These channels act like tiny \u201cgates\u201d in the cell membrane that open when cells are stretched, thereby regulating the activity of cells. They help bone cells and immune cells sense their environment and respond to changes. We focus on three groups of these channels: K2P channels influence how bone-building cells (osteoblasts) grow and how immune cells control inflammation. Piezo channels help bone cells sense mechanical forces and control immune cell behavior. Volume-regulated anion channel channels may help bone cells adapt to stress and regulate inflammatory signals. Because of their dual effect on mechanical and inflammatory signaling, changes/alterations in ion channel activity may contribute to bone loss in osteoporosis. Pharmacological targeting of these channels could therefore help to protect bone. Early studies suggest that drugs influencing mechanosensitive ion channels might one day prevent or slow down osteoporosis. More research is needed, but this approach opens exciting new possibilities for treatment."

The lung is an attractive site for local intervention because it is directly accessible and immunologically specialized. However, effective pulmonary delivery is constrained by mucociliary clearance, airway mucus, alveolar macrophage uptake, and epithelial barriers. Nanomaterials can be rationally engineered to address these constraints, increasing pulmonary retention and concentrating immunotherapeutics within the lung tumor microenvironment while reducing systemic burden. This Review summarized the key physiological barriers for pulmonary immunotherapeutic delivery and discusses how nanomaterial properties shape deposition, retention, cellular partitioning, and downstream immune activation. We critically evaluate representative inhalable platforms across major immunotherapeutic modalities, including vaccines, immune checkpoint blockade, innate immune agonists (e.g., STING agonists), cytokine regulation, and emerging in situ immune-cell engineering strategies. We also highlight translational considerations. Together, these advances support inhalable immunotherapeutic nanomedicines as a complementary approach to current lung cancer treatment and a broader framework for pulmonary immune modulation."

Inspired by these bio-geometries, we explore how nanoscale anisotropy can be engineered to control the dynamic transport and biodistribution of synthetic nanocarriers in the body. We fabricate anisotropic silica nanocapsules with precisely tunable asymmetry to dissect shape effects on nano-bio interactions under physiological flow. Under shear flow in vitro, increasing anisotropy markedly reduced cellular uptake, whereas this effect was much less pronounced under static conditions, revealing strong flow-shape coupling. In vivo, highly anisotropic nanocapsules exhibit prolonged circulation, with a 2.8-fold longer half-life than spherical counterparts and significantly reduced sequestration by the liver, spleen, and circulating blood cells. Mechanistic analyses attributed these effects to decreased phagocytic internalization by Kupffer cells, splenic macrophages, and circulating monocytes. Computational fluid dynamics simulations corroborated this phenomenon, demonstrating that greater anisotropy shifts particle trajectories away from vessel walls toward the central flow stream, lowering the chances of cellular interception. Together, these results establish nanoscale anisotropy as a critical determinant of nanoparticle transport, immune recognition, and clearance under flow. Anisotropy engineering therefore provides a nature-inspired framework for designing long-circulating, immune-evasive nanocarriers with improved therapeutic performance."

The origin of phagocytosis and its role in the evolution of endomembranes and the eukaryotic cell remains obscure. Drawing on a wealth of empirical data, we integrate prey capture, engulfment, and internal and external digestion into a mathematical evolutionary model that quantifies the fitness of a primitive phagocytoser relative to a non-phagocytosing ancestor. We reveal the conditions under which a non-phagocytosing predator that digests its prey externally can persist. We also show that the phagocytoser can outperform the ancestor in a broad range of situations, despite the cost associated with producing a phagocytic cup. Parameter variations delineate how fast engulfment needs to be for phagocytosis to be advantageous, providing clear benchmarks for interpreting the importance of results in genetic knockout studies and mechanical models. The phagocytoser still outperforms the ancestor when food vacuoles can't fuse back to the plasma membrane, providing arguments in favor of the gradual evolution of phagocytosis and for phagocytosis as the initiator of the endomembrane system."

Notably, metabolic rewiring can imprint long-lasting epigenetic changes, a phenomenon known as innate immune memory, which alters subsequent immune responses.

Increasing evidence indicates that this failure is not determined solely by PD-1, PD-L1, CTLA-4, or T-cell exhaustion, but also by metabolically suppressive states within the tumor microenvironment. Tumor-derived metabolites can function as metabolic immune checkpoints by limiting effector immune activity, promoting regulatory or myeloid suppressive compartments, and weakening immunotherapy efficacy. This mini review summarizes recent experimental evidence showing how lactate, adenosine, tryptophan-derived metabolites, and nucleotide-derived metabolites shape immune escape and resistance to immune checkpoint blockade. Lactate links tumor glycolysis to Treg recruitment, impaired T-cell function, and lactylation-associated therapeutic resistance. The CD73-adenosine axis suppresses CD8+ T cells and natural killer cells while reinforcing regulatory and myeloid immune programs. Tryptophan-derived metabolites extend beyond the classical IDO1-kynurenine-AhR pathway to involve non-classical checkpoints such as Siglec-15 and broader kynurenine/indole/serotonin networks. Emerging evidence further identifies nucleotide-derived UDP signaling as a driver of macrophage-mediated immunosuppression. Finally, we discuss how targeting metabolic checkpoints in combination with immune checkpoint blockade may improve therapeutic responses.

The chapter details its significance across both innate and adaptive immunity, including T cell activation and migration, macrophage polarization, dendritic cell activation, natural killer cell cytotoxicity, neutrophil extracellular trap (NET) formation, and B cell antigen discrimination and class-switching to IgA. PIEZO1 emerges as a central regulator that fine-tunes immune responses by integrating signals from the cellular microenvironment, influencing inflammation, pathogen clearance, and metabolic reprogramming. Despite these advances, key questions remain regarding its role in chronic disease, autoimmunity, and cancer immunity. Targeting PIEZO1 presents a promising therapeutic strategy for conditions driven by mechanical stress and immune dysfunction, such as fibrosis, atherosclerosis, and solid tumours, potentially inaugurating a new era of mechano-immunotherapy."

Currently, there are few approved clinical therapies that specifically target white matter repair to enhance functional recovery after stroke. We demonstrated that microglial adenosine 2A receptor (A2AR) is essential for spontaneous white matter regeneration after ischemic injury in mice. Deletion of A2AR in microglia specifically impaired chronic-phase repair without altering the severity of acute ischemic injury. Pharmacological activation of A2AR signaling with blood-brain barrier-permeable agonistic micelles during the early reperfusion phase enhanced white matter structural repair and led to sustained improvements in cognitive and sensorimotor function in mice. Mechanistically, A2AR activation promoted microglial efferocytosis of apoptotic cells and myelin debris in the lesioned white matter, thereby limiting secondary necrosis-induced inflammation, enhancing neurotrophic factor release, and establishing a reparative microenvironment conducive to oligodendrocyte precursor cell differentiation and remyelination. Moreover, A2AR signaling engaged HIF1\u03b1-dependent metabolic reprogramming to increase glycolysis, thereby providing the energetic support required for efficient and sustained efferocytosis. Together, these findings identify A2AR as a critical regulator of microglia-mediated white matter repair and a promising therapeutic target for enhancing regeneration after stroke."

Here, we found that the mechanosensitive ion channel Piezo1 was up-regulated in hepatic fibrosis. Macrophages lacking Piezo1 showed sustained inflammation and impaired spontaneous resolution of early liver fibrosis. Further analysis revealed an impairment of clearance of apoptotic cells by macrophages in the fibrotic liver. Macrophages showed enhanced efferocytosis when cultured on rigid substrates but not soft ones, suggesting stiffness-dependent efferocytosis of macrophages required Piezo1 activation. Besides, Piezo1 was involved in the efficient acidification of the engulfed cargo in the phagolysosomes and affected the subsequent expression of anti-inflammation genes after efferocytosis. Pharmacological activation of Piezo1 increased the efferocytosis capacity of macrophages and accelerated the resolution of inflammation and fibrosis.

However, concurrent immunosuppression may compromise vaccine efficacy. This study investigated the effect of immunosuppression induced by either chicken anaemia virus (CAV) or infectious bursal disease virus (IBDV), administered prior to or following vaccination with the M. gallisepticum live vaccine strain ts-304 (Vaxsafe MG304), on tracheal host responses to subsequent challenge with virulent M. gallisepticum. Tracheal responses were assessed by genome-wide transcriptional profiling in these groups and compared across unvaccinated-unchallenged, unvaccinated-challenged, vaccinated-unchallenged and vaccinated-challenged groups that had not been exposed to CAV or IBDV. Immunosuppression resulted in significant differences in tracheal transcriptional responses compared to immunocompetent groups, irrespective of the timing of infection with CAV or IBDV. Differences in transcription were more pronounced in the IBDV-infected groups than the CAV-infected groups. Functional interrogation of differentially transcribed genes revealed adverse effects of M. gallisepticum on extracellular and intracellular signalling, cell communication, cellular actin dynamics, formation of the cellular cytoskeleton, and cellular metabolic pathways in the tracheal mucosa of immunosuppressed groups. In addition, there were indications of down-regulation of both innate and adaptive immune responses, including cytokine signalling, antigen processing presentation, and immune cell receptor signalling in the immunosuppressed groups. Specifically, findings indicated that infection with CAV impaired pro-inflammatory and adaptive T-cell responses in the tracheal mucosa. The findings implied that the primary immune response induced post-vaccination and the secondary immune response induced post-challenge with virulent M. gallisepticum were both affected by infection with these two viruses. Coupled with previous observations of reduced antibody titres against M. gallisepticum, and increased rates of recovery of virulent M. gallisepticum in both CAV- and IBDV-infected groups, the significant transcriptional changes detected in the current study highlighted the roles of both cell-mediated (CMI) and humoral immunity (HI) in vaccine-induced protection, as CAV mainly affects CMI and IBDV mainly affects HI. These findings will assist in identifying the mechanisms underlying the reduced efficacy of live attenuated mycoplasma vaccines in immunosuppressed animals."

Class I myosins Myo1e and Myo1f (Myo1e/f) have been implicated in linking the plasma membrane to the actin network, but their specific roles during Fc-receptor-mediated phagocytosis remain unclear. Using CRISPR-edited RAW 264.7 macrophages lacking Myo1e and Myo1f, we show that double knockout (dKO) cells exhibit markedly reduced uptake of IgG-coated beads, a phenotype that is partially rescued by re-expression of either myosin. Lattice-light-sheet and confocal imaging revealed distinct F-actin architectures corresponding to the various stages of cup progression, including basal podosome-like adhesions, individual phagocytic podosomes (actin teeth) along the rim of the cup, and a contractile phagocytic ring formed by the reorganization of podosomes into a higher-order network. In Myo1e/f-deficient cells, podosome formation was diminished, actin teeth were largely absent, and the phagocytic ring formed prematurely, which was often accompanied by stalled cup progression and repeated engulfment attempts. Myo1e/f localized both to podosomes and to the inner surface of the phagocytic ring, non-muscle myosin II (NM2) localized to the outer surface, and the absence of Myo1e/f correlated with the diffuse distribution of NM2. In addition, Myo1e/f-deficient macrophages exhibited increased trogocytosis of antibody-opsonized HL-60 cells, indicating a shift from whole-target engulfment toward partial target ingestion. These results suggest that Myo1e/f coordinate spatial and temporal transitions between protrusive and contractile actin networks, thereby ensuring efficient phagocytic cup progression. Our findings highlight a dual role for Myo1e/f in adhesion regulation and force balance during macrophage phagocytosis."

"abstract_text": "ID: 40741709\nTitle: Depletion of endomembrane reservoirs drives phagocytic appetite exhaustion in macrophages.\nAbstract: During phagocytosis, a phagocytic cup grows via F-actin remodeling and localized secretion to entrap a particle within a phagosome, which then fuses with endosomes and lysosomes to digest the particle, followed by phagosome resolution. As spatially limited systems, phagocytes have a maximal phagocytic capacity, at which point further uptake must be reduced. However, the processes responsible for phagocytic appetite exhaustion as phagocytes reach their maximal phagocytic capacity are poorly defined. We found that macrophages at their capacity have lower surface levels of Fc\u03b3 receptors but overexpression of these receptors did not increase their capacity, suggesting that receptor levels are not limiting. We found that surface membrane in-folding, membrane tension and cortical F-actin were all reduced in exhausted macrophages. Although this might contribute to appetite suppression, we also found that 'free' endosomes and lysosomes were severely depleted in exhausted macrophages. Consequently, focal exocytosis at sites of externally bound particles was reduced. In comparison, macrophages recovered their appetite if phagosome resolution was permitted. We propose that depletion of the endomembrane pools is a major determinant of phagocytic fatigue as macrophages reach their phagocytic capacity."

During phagocytosis, macrophages internalize and degrade pathogens and apoptotic cells by forming the phagocytic cup and phagosome. Osteoclasts resorb bone by forming the sealing zone and ruffled border at the ventral membrane. This review explores the organizational principles of these dynamic structures. In in vitro frustrated phagocytosis, specifically 2D phagocytosis by macrophages, the activation of the Fc\u03b3 receptor generates multiple self-organized waves containing F-actin, Arp2/3, and phosphoinositides. The propagation of these circular actin waves segregates the inside from the outside, leading to the compartmentalization of the ventral membrane. As the actin wave passes, cortical actin is disrupted, and membrane remodeling occurs within the wave, creating a new membrane domain with high exocytic activity. These processes mirror the formation of the constriction zone in the phagocytic cup and phagosome during 3D phagocytosis. A similar mechanism may also contribute to the formation of the sealing zone and ruffled border in osteoclasts. Based on these observations, we propose that dynamic structures formed from actin waves are organized through the fractal integration of self-organized, oscillatory substructures, with F-actin treadmilling fueling their formation and maintenance."

While a number of mathematical models have been developed to describe this process, they often overlook membrane tension, a key physical parameter known to influence membrane deformation and cytoskeletal behaviour. To address this gap, we present an enhanced mathematical model of receptor motion during phagocytosis that explicitly incorporates the role of membrane tension. Further, we introduce a signalling component that is coupled to receptor dynamics via the membrane tension. We find that including tension results in fundamentally different engulfment behaviour, which is slower than that predicted by models without tension. In particular, unlike in the previous version of this model, we show that tension can lead to stalled engulfment, an experimentally-observed phenomenon known as frustrated phagocytosis. We also find that signalling is able to modify engulfment behaviour, especially at later stages, and is able to alter cup growth to become linear in time without the need for receptor drift as introduced in previous models. These findings offer new insights into the role of membrane tension and biophysical regulation in phagocytosis, with implications for immune function, cell motility and targeted drug delivery."

Syk owns two SH2 domains that interact with biphosphorylated ITAMs of the Fc\u03b3R upon phagocytosis. This results in the activation of Syk by autophosphorylation, triggering phosphorylation of several downstream targets, F-actin polymerization, and phagocytosis of the IgG-opsonized target. We found that Syk is S-acylated upon phagocytosis by macrophages. Palmitoylation is performed on a single Syk-Cys by the DHHC5 enzyme that specifically associates with Syk upon phagocytosis. Syk palmitoylation is important for Syk localization to the phagocytic cup, phosphorylation, and phagocytosis. We observed that another Syk-Cys residue, within a redox motif, is modified by sulfenylation. Nevertheless, Syk desulfenylation seems to occur during phagocytosis, when H2O2 production at the cup decreases, after 3.5 min of phagocytosis. Molecular dynamics studies indicated that desulfenylation increased the exposure of a loop within the Syk interdomain B. This could facilitate phosphorylation of key Syk-Tyr residues by upstream kinases. We thus propose an updated model for Syk activation during Fc\u03b3R-mediated phagocytosis that involves both Syk palmitoylation and desulfenylation."

"abstract_text": "ID: 41071099\nTitle: Mechanosensitive ion channels as novel targets in osteoporosis.\nAbstract: Osteoporosis is the most prevalent metabolic bone disease globally, leading to an increased risk of fractures. Recent advances in ion channel research have shed light on the importance of mechanosensitive ion channels as novel players in these pathophysiological processes. This perspective discusses the involvement of the mechanosensitive ion channels TREK-1, Piezo, and volume-regulated anion channels (VRACs) as potential novel pharmacological targets for the treatment of osteoporosis. TREK-1, a mechanosensitive K2P channel is important for maintaining the resting membrane potential in many cells, including osteoblasts and osteoclasts. K2P channels regulate osteoblast proliferation and differentiation, as well as osteoclast activity, potentially modulating bone remodeling in osteoporosis. Piezo channels influence osteoblast differentiation and osteoclast activity by modulating calcium influx, which is crucial for osteogenic signaling pathways, such as Wnt/\u03b2-catenin and ERK1/2. Piezo1 activation promotes bone formation, while its deficiency leads to impaired osteogenesis and increased bone resorption. Volume-regulated anion channels have been shown to be involved in osteoblast adaptation to mechanical stress and macrophage polarization, which indicates their importance for bone homeostasis. Chronic inflammation is a major contributor to osteoporosis progression. Evidence of ion channel involvement in this process has emerged in recent years. Specifically, macrophage function in osteoporosis seems to be linked to ion channel activity. Inflammatory polarization of macrophages is a key player in inflammation-induced bone loss and can be driven by mechanosensitive ion channels. Modulating these ion channels may provide new therapeutic opportunities. Given the complexity of ion channel interactions in bone cells and their regulatory role in bone remodeling, understanding their precise function in osteoporosis is essential. Targeted modulation of mechanosensitive ion channels holds promise as a novel therapeutic approach to mitigate inflammation-driven bone loss and improve bone density. Further research into their role in osteoclasts and macrophage-driven bone degradation will aid in developing innovative osteoporosis treatments. Osteoporosis is the most common bone disease worldwide. The exact reasons for why bones weaken is often not fully understood, which makes the development of targeted therapies difficult. Our article highlights a new perspective: certain proteins in bone cells, called mechanosensitive ion channels, may be key players in osteoporosis. These channels act like tiny \u201cgates\u201d in the cell membrane that open when cells are stretched, thereby regulating the activity of cells. They help bone cells and immune cells sense their environment and respond to changes. We focus on three groups of these channels: K2P channels influence how bone-building cells (osteoblasts) grow and how immune cells control inflammation. Piezo channels help bone cells sense mechanical forces and control immune cell behavior. Volume-regulated anion channel channels may help bone cells adapt to stress and regulate inflammatory signals. Because of their dual effect on mechanical and inflammatory signaling, changes/alterations in ion channel activity may contribute to bone loss in osteoporosis. Pharmacological targeting of these channels could therefore help to protect bone. Early studies suggest that drugs influencing mechanosensitive ion channels might one day prevent or slow down osteoporosis. More research is needed, but this approach opens exciting new possibilities for treatment."

The lung is an attractive site for local intervention because it is directly accessible and immunologically specialized. However, effective pulmonary delivery is constrained by mucociliary clearance, airway mucus, alveolar macrophage uptake, and epithelial barriers. Nanomaterials can be rationally engineered to address these constraints, increasing pulmonary retention and concentrating immunotherapeutics within the lung tumor microenvironment while reducing systemic burden. This Review summarized the key physiological barriers for pulmonary immunotherapeutic delivery and discusses how nanomaterial properties shape deposition, retention, cellular partitioning, and downstream immune activation. We critically evaluate representative inhalable platforms across major immunotherapeutic modalities, including vaccines, immune checkpoint blockade, innate immune agonists (e.g., STING agonists), cytokine regulation, and emerging in situ immune-cell engineering strategies. We also highlight translational considerations. Together, these advances support inhalable immunotherapeutic nanomedicines as a complementary approach to current lung cancer treatment and a broader framework for pulmonary immune modulation."

Inspired by these bio-geometries, we explore how nanoscale anisotropy can be engineered to control the dynamic transport and biodistribution of synthetic nanocarriers in the body. We fabricate anisotropic silica nanocapsules with precisely tunable asymmetry to dissect shape effects on nano-bio interactions under physiological flow. Under shear flow in vitro, increasing anisotropy markedly reduced cellular uptake, whereas this effect was much less pronounced under static conditions, revealing strong flow-shape coupling. In vivo, highly anisotropic nanocapsules exhibit prolonged circulation, with a 2.8-fold longer half-life than spherical counterparts and significantly reduced sequestration by the liver, spleen, and circulating blood cells. Mechanistic analyses attributed these effects to decreased phagocytic internalization by Kupffer cells, splenic macrophages, and circulating monocytes. Computational fluid dynamics simulations corroborated this phenomenon, demonstrating that greater anisotropy shifts particle trajectories away from vessel walls toward the central flow stream, lowering the chances of cellular interception. Together, these results establish nanoscale anisotropy as a critical determinant of nanoparticle transport, immune recognition, and clearance under flow. Anisotropy engineering therefore provides a nature-inspired framework for designing long-circulating, immune-evasive nanocarriers with improved therapeutic performance."

Cellular responses were assessed through analyses of cytotoxicity, immunocytochemistry and cytokine profiling. NPs exposure did not induce acute cytotoxicity but promoted persistent intracellular retention accompanied by lysosomal dysfunction, dysregulated autophagic flux, ER stress, and constrained mitochondrial function, thereby inducing a sublethal multi-organelle stress response. Macrophages exhibited greater vulnerability consistent with phagocytic burden, while inflammatory challenge further enhanced NPs uptake, reinforcing intracellular persistence. In contrast, neurons showed limited extracellular cytokine secretion yet accumulated intracellular IL-1\u03b2, suggesting low-grade inflammatory activation. Such responses were recapitulated in PCNs, supporting translational relevance across neuronal models. The cumulative nature of these observations suggests that NPs exposure may give rise to previously unrecognized accumulation-related pathologies, a phenomenon we term \"plasticoma\" as a conceptual framework, to describe the preferential deposition of non-degradable plastic particles within cells, to frame and stimulate future investigations into NP accumulation and pathology. These findings position NPs as potential determinant of neuroimmune dysfunction and highlight the importance of strategies aimed at mitigating their biological accumulation."

Increasing evidence indicates that this failure is not determined solely by PD-1, PD-L1, CTLA-4, or T-cell exhaustion, but also by metabolically suppressive states within the tumor microenvironment. Tumor-derived metabolites can function as metabolic immune checkpoints by limiting effector immune activity, promoting regulatory or myeloid suppressive compartments, and weakening immunotherapy efficacy. This mini review summarizes recent experimental evidence showing how lactate, adenosine, tryptophan-derived metabolites, and nucleotide-derived metabolites shape immune escape and resistance to immune checkpoint blockade. Lactate links tumor glycolysis to Treg recruitment, impaired T-cell function, and lactylation-associated therapeutic resistance. The CD73-adenosine axis suppresses CD8+ T cells and natural killer cells while reinforcing regulatory and myeloid immune programs. Tryptophan-derived metabolites extend beyond the classical IDO1-kynurenine-AhR pathway to involve non-classical checkpoints such as Siglec-15 and broader kynurenine/indole/serotonin networks. Emerging evidence further identifies nucleotide-derived UDP signaling as a driver of macrophage-mediated immunosuppression. Finally, we discuss how targeting metabolic checkpoints in combination with immune checkpoint blockade may improve therapeutic responses. Defining the spatial and cellular contexts of metabolite-mediated immune suppression may enable more precise strategies to overcome immunotherapy resistance."

Thirty participants with extreme annualised WBR change (\u0394WBR/yr) were selected. Baseline serum samples collected at enrolment, prior to outcome occurrence, were analysed using phage immunoprecipitation sequencing (PhIP-Seq). Cross-sectionally, WBR was negatively correlated with bone mineral density and appendicular skeletal muscle mass index and positively correlated with osteopenia, sarcopenia, SOs, SOb and fractures (all p\u2009<\u20090.01), whereas BMI, WC, WHtR and WHR showed weaker associations. After adjustment, higher WBR was independently associated with osteopenia (men: OR 1.723, 95% CI 1.614-1.840; women: OR 1.420, 1.348-1.495), sarcopenia (men: OR 4.779, 4.165-5.484; women: OR 2.991, 2.683-3.334), SOs (men: OR 6.261, 5.314-7.377; women: OR 4.336, 3.753-5.010), SOb (men: OR 4.737, 3.975-5.646; women: OR 4.652, 3.715-5.825) and fractures (men: OR 1.236, 1.093-1.397; women: OR 1.103, 1.003-1.213; all p\u2009<\u20090.05). Prospectively, higher time-dependent WBR predicted incident osteopenia (HR 1.365, 95% CI 1.024-1.820), sarcopenia (HR 1.282, 1.086-1.512), SOs (HR 1.408, 1.176-1.686), SOb (HR 1.634, 1.262-2.116) and fractures (HR 1.369, 1.029-1.821). PhIP-Seq analysis identified differential autoantibody reactivity related to muscle structural organisation and cytoskeletal regulation, while bone-related differences were enriched in Wnt signalling and hormone-related pathways. Higher WBR and longitudinal increases were independently associated with osteopenia, sarcopenia, sarcopenic phenotypes and fractures in individuals with T2DM."

Myosin motor functions are regulated by adaptor proteins that mediate cargo attachment and motor recruitment. To define the MYO1F interactome, we used in situ proximity labelling and proteomics in human myeloid cells. We identified a distinct SH3-domain-dependent adaptor module comprising CD2AP, ASAP1, SH3BP2 and SH3KBP1 (herein termed the CASS group of proteins). Interestingly, CD2AP is an Alzheimer's disease (AD) risk gene upregulated in the microglia of individuals with AD, which are implicated in phagocytic responses to amyloid-\u03b2. Structural modelling and mutagenesis confirmed multivalent proline-rich motif interactions between the CASS group of proteins and the MYO1F SH3 domain. Additional binding partners associate with the MYO1F pleckstrin homology (PH) domain. Immunofluorescence revealed colocalisation of MYO1F and the CASS group of proteins at actin-rich podosomes and phagocytic cups in macrophages and microglia. Functional assays demonstrated that MYO1F recruitment to the phagocytic cup requires motor activity and intact PH and SH3 domains. We provide the first MYO1F interactome identifying adaptor proteins for MYO1F in podosomes and during phagocytosis, offering new insights into its function in disease-associated microglia during neurodegeneration."

Here, we found that the mechanosensitive ion channel Piezo1 was up-regulated in hepatic fibrosis. Macrophages lacking Piezo1 showed sustained inflammation and impaired spontaneous resolution of early liver fibrosis. Further analysis revealed an impairment of clearance of apoptotic cells by macrophages in the fibrotic liver. Macrophages showed enhanced efferocytosis when cultured on rigid substrates but not soft ones, suggesting stiffness-dependent efferocytosis of macrophages required Piezo1 activation. Besides, Piezo1 was involved in the efficient acidification of the engulfed cargo in the phagolysosomes and affected the subsequent expression of anti-inflammation genes after efferocytosis. Pharmacological activation of Piezo1 increased the efferocytosis capacity of macrophages and accelerated the resolution of inflammation and fibrosis. Our study supports the antifibrotic role of Piezo1-mediated mechanical sensation in liver fibrosis, suggesting that targeting PIEZO1 to enhance macrophage efferocytosis could induce fibrosis regression."

Evidence supports that modulation of specific pathways (e.g., A2AR, MerTK, JAK/STAT, and mitochondrial metabolism) can enhance efferocytosis across diverse states.\n\n### [INTRODUCTION & JUSTIFICATION]\nThe paradigm of macrophage polarization as a binary M1/M2 system is increasingly superseded by the recognition of a functional continuum dictated by metabolic plasticity. Efferocytosis is an energy-demanding process that requires specific signaling cues, such as those initiated by IL-33 or Gas-6, and metabolic support, such as HIF1\u03b1-dependent glycolysis. While inflammation-associated (M1-like) macrophages are traditionally viewed as pro-inflammatory, evidence demonstrates that they can be reprogrammed to exhibit enhanced efferocytosis through targeted interventions. For instance, A2AR activation promotes efferocytosis to accelerate repair, and the induction of specific receptors like MerTK allows for the efficient engulfment of debris, bridging the gap between pro-inflammatory states and the resolution of inflammation.\n\n### [DISCUSSION: NOVEL & OVERLOOKED]\n* Efferocytosis acts as a primary resolution driver that can be pharmacologically bolstered, even in chronic inflammatory states, through the activation of specific ion channels like Piezo1.\n* Metabolic sensors like A2AR link microenvironmental triggers to the cellular machinery required for myelin and apoptotic cell clearance.\n* The expression of CD3 on macrophages, traditionally a T-cell marker, suggests a previously uncharacterized layer of complexity in how myeloid cells integrate signaling pathways during stress.\n* Natural polysaccharides show potential in metabolic regulation of macrophages, influencing polarization and inflammatory output through the modulation of pathways like NF-\u03baB and MAPK.\n* Circulating cochlin LCCL domain serves as an exogenous efferocytosis-promoting factor, highlighting the role of systemic serum proteins in local tissue repair.\n* Fetal sex significantly shapes maternal monocyte metabolic programming, with pEVs inducing sex-dependent shifts in efferocytic activity.\n* Non-functional isoforms of P2X7 in cancer cells reveal how malignant cells bypass the regulated scavenger receptor pathways typically used by macrophages.\n\n### [EVIDENCE, METHODOLOGY & CITATIONS]\n1.

While Piezo1 activation enhances efferocytosis in pro-inflammatory macrophages, the literature identifies this as a metabolically-linked pathway (involving glycolysis and HIF1\u03b1) rather than a simple override of metabolic constraints via non-transcriptional actin remodeling.\n\n### [ABSTRACT & REWRITTEN CLAIM]\nPiezo1 is a mechanosensitive ion channel involved in regulating macrophage function, particularly efferocytosis. Research suggests that while Piezo1-mediated calcium influx is central to this process, its activity is integrated with metabolic pathways (e.g., HIF1\u03b1-mediated glycolysis). There is currently insufficient evidence to conclude that Piezo1 can \"override\" metabolic depletion solely through rapid, non-transcriptional actin remodeling; rather, evidence supports that Piezo1 activity depends on energy-intensive pathways.\n\n### [INTRODUCTION & JUSTIFICATION]\nMacrophages depend on sophisticated cytoskeletal remodeling to facilitate the engulfment of apoptotic targets. The process requires highly coordinated actin dynamics, as \"Phagocytosis requires coordinated remodeling of the actin cytoskeleton to generate protrusive and contractile forces that drive target engulfment.\" Piezo1 acts as a professional mechanosensor that converts environmental signals into physiological functions, noting that \"PIEZO1 emerges as a central regulator that fine-tunes immune responses by integrating signals from the cellular microenvironment, influencing inflammation, pathogen clearance, and metabolic reprogramming.\" In the context of liver fibrosis and myocardial infarction, Piezo1 has been shown to modulate efferocytosis, where \"Pharmacological activation of Piezo1 increased the efferocytosis capacity of macrophages and accelerated the resolution of inflammation and fibrosis.\" However, this process is not independent of metabolic state, as \"A2AR signaling engaged HIF1\u03b1-dependent metabolic reprogramming to increase glycolysis, thereby providing the energetic support required for efficient and sustained efferocytosis.\" The claim that Piezo1 overrides metabolic limitations remains speculative because the evidence shows metabolic pathways (like glycolysis) are recruited to support the increased energetic demand of phagocytosis, and \"Piezo1 was involved in the efficient acidification of the engulfed cargo in the phagolysosomes and affected the subsequent expression of anti-inflammation genes after efferocytosis.\"\n\n### [DISCUSSION: NOVEL & OVERLOOKED]\n* Piezo1 acts as a metabolic integrator rather than just a mechanical gate, linking ion flux to downstream transcriptional pathways like the ATF4/SLC7A11 axis.\n* Myocardial infarction creates an environment where Piezo1 is upregulated; paradoxically, this can be maladaptive in certain contexts, as \"Piezo1 activation aggravated OGD-induced macrophage ferroptosis via Ca2+ influx followed by SLC15A3 upregulation.\"\n* Actin remodeling for phagocytosis is not only dependent on Piezo1 but also involves specific molecular motor proteins and adaptors like MYO1F, which coordinate the phagocytic cup formation.\n* Macrophages face \"phagocytic appetite exhaustion\" when endomembrane pools are depleted, indicating that mechanical activation (like Piezo1) cannot substitute for fundamental cellular resource availability.\n* The transition between pro-inflammatory (M1) and pro-resolving (M2) phenotypes is heavily influenced by metabolic reprogramming (e.g., glycolysis vs. OXPHOS) and epigenetic modifiers, which Piezo1 signaling helps regulate.\n\n### [EVIDENCE, METHODOLOGY & CITATIONS]\n1.

RAW264.7 cells were randomly divided into the normal control group, oxidized low-density lipoprotein(ox-LDL) group, HLJDD group, simvastatin(simva) group, and RAW264.7-ERK5 gene knockout(ERK5-KO) group. According to the experimental protocol, cells in each group were treated for 24 h with normal control rat serum, ox-LDL, HLJDD-containing serum, or simva-containing serum. Apoptotic Jurkat cells were added to each group and co-cultured for 90 min. After removal of the supernatant, LC3-\u2161 labeling was performed to observe LAPosomes in macrophages, and the clearance of apoptotic Jurkat cells was assessed. The expression levels of phosphorylated(p)-ERK5, ERK5, LAP-related signaling molecules [T-cell immunoglobulin and mucin-domain-containing molecule-4(TIM-4), vacuolar protein sorting 34(VPS34), Beclin-1, RUN domain Beclin-1-interacting and cysteine-rich domain-containing protein(Rubicon), autophagy-related protein 5(ATG5), and autophagy-related protein 7(ATG7)], pro-inflammatory cytokines [interleukin-1\u03b2(IL-1\u03b2), interleukin-6(IL-6)], and anti-inflammatory cytokines [interleukin-10(IL-10), transforming growth factor-\u03b2(TGF-\u03b2)] were measured. RESULTS:: showed that, compared with the control group, the ox-LDL group exhibited decreased LAPosome percentage and reduced clearance of apoptotic cells, downregulated expression of p-ERK5, TIM-4, VPS34, Beclin-1, Rubicon, ATG5, and ATG7, increased IL-1\u03b2 and IL-6 levels, and no significant changes in IL-10 or TGF-\u03b2 expression. Compared with the ox-LDL group, the HLJDD and simva groups showed increased LAPosome percentage and enhanced apoptotic cell clearance, upregulated expression of p-ERK5, TIM-4, VPS34, Beclin-1, Rubicon, ATG5, and ATG7, decreased IL-1\u03b2 and IL-6 levels, and increased IL-10 and TGF-\u03b2 expression. Compared with the HLJDD group, the ERK5-KO group exhibited significantly reduced expression of ERK5 and p-ERK5, and all other indicators were reversed. In conclusion, HLJDD may ameliorate macrophage LAP dysfunction and exert anti-AS effects by activating ERK5."

IL-33 is an alarmin that initiates type 2 immune responses, including increased production of IL-13, which promotes MerTK expression. The ability of IL-33 to promote efferocytosis in vivo was examined. Intraperitoneal administration of IL-33 to mice increased local MerTK+ macrophage numbers within 48h. MerTK+ macrophages were not similarly induced by free mitochondria, an alternative cell damage associated signal. Efferocytotic activity was increased rapidly in response to apoptotic thymocytes in IL-33-treated mice. The established inducer of MerTK expression, IL-13, was detected in peritoneal lavage fluid shortly after IL-33 administration. Peritoneal eosinophils expressed the IL-33 receptor and demonstrated both intracellular IL-13 by flow cytometry and significantly increased Il13 transcript expression following IL-33 treatment. In contrast, neither elevated IL-13 expression nor IL-13 protein secretion was observed in peritoneal lymphocyte populations within the first 6 hours after IL-33 administration. Primary cultures of bone marrow-derived mouse mast cells and eosinophils demonstrated IL-13 protein responses to IL-33 administration within 6\u00a0h. Mast cell-deficient Cpa3-Cre; Mcl-1fl/fl mice had significantly reduced IL-13 levels in the peritoneal cavity 3 hours after IL-33 administration when compared with mast cell-containing littermates. In contrast, IL-33-treated eosinophil-deficient \u0394dblGATA mice had similar levels of IL-13 at this time point as wild type controls. These data demonstrate that IL-33 promotes MerTK expression, critical for efferocytosis by macrophages, by a process associated with an early rapid local increase in IL-13 production to which mast cells are a substantial early contributor. These findings contribute to our understanding of clinical situations where elevated soluble IL-33 receptor (sST2) and/or lower mast cell numbers are associated with worse clinical outcome."

Defective efferocytosis has been associated with autoimmune, neurodegenerative, and cardiovascular diseases, as well as chronic infections, making its regulation a potential therapeutic target. Here, we identify circulating cochlin LCCL (Limulus factor C, Cochlin, and Lgl1) domain as a regulator of efferocytosis. Using cell binding assay for recombinant cochlin LCCL domain, we establish its tropism for dead or dying cells of both immune and non-immune lineages from murine and human origins. By three independent functional assays, we demonstrate that endogenous and exogenous cochlin LCCL domain enhances macrophage efferocytosis in vitro and in vivo in lipopolysaccharide (LPS)-induced inflammation and intranasal Pseudomonas aeruginosa infection, to a similar extent as the efferocytosis promoter GAS6. Our findings provide a role of cochlin LCCL domain in the regulation of efferocytosis, alongside its already described pro-inflammatory role, as an immunomodulator for host response and homeostasis."

G protein-coupled receptor 146 (GPR146) has emerged as a pivotal regulator of systemic cholesterol metabolism; however, its role in the central nervous system and AD remains elusive. Here, we report that GPR146 deficiency in mice modulates ERK/PKA signaling without affecting baseline physiology or general behavior. Following intracerebroventricular (i.c.v.) injection of amyloid-\u03b2 (A\u03b2)42 oligomers, GPR146 was associated with altered A\u03b242-evoked ERK/PKA/Akt signaling both in vivo and in vitro. Mechanistically, Gpr146 ablation potentiated microglial A\u03b2 phagocytosis, which correlated with the transcriptional upregulation of phagocytic receptors, including TREM2, GPR34, P2Y6, and CR3, alongside increased expression of pro-inflammatory cytokines (TNF-\u03b1, IL-1\u03b2, IL-6). Moreover, GPR146 deficiency was linked to elevated levels of blood-brain barrier (BBB)-associated markers Cldn-5 and Glut-1 protein levels, while attenuating A\u03b2\u2011induced inflammatory responses in brain endothelial cells. At the metabolic level, GPR146 knockout modulated the expression of key enzymes governing glucose (GLUT1, GLUT3, G6PD, PFK, HK) and lipid (HMGCS1, ACACA, FASN, SCD1) metabolism and markedly reduced A\u03b2\u2011elicited lipid droplet accumulation in the cortex and hippocampus. Collectively, our findings establish GPR146 as a novel neurometabolic regulator whose deficiency correlates with enhanced A\u03b2 phagocytosis, maintenance of BBB-associated proteins, and altered cerebral metabolism, thereby presenting a potential therapeutic axis for early AD intervention."

This neoplasm can present with different nonspecific symptoms, including fever, altered mental status, livedoid skin rashes, hepatosplenomegaly, and cytopenias, often complicating its diagnosis. The main categories are classical (formerly designated as Western), hemophagocytic variant (formerly designated as Asian), and primary cutaneous IVLBCL. A distinctly severe manifestation is hemophagocytic lymphohistiocytosis (HLH), a hyperinflammatory syndrome characterized by exaggerated immune activation and macrophage activation manifested by phagocytosis of hematopoietic cells including neutrophils, red blood cells, and platelets. We describe a 72-year-old female who presented with features reminiscent of an autoinflammatory syndrome including fever and hyperferritinemia followed by clinical features concerning for HLH. She developed a reticulated skin rash. Following skin biopsy, a diagnosis was rendered of IVLBCL complicated by HLH. The pathophysiology and other aspects of the literature pertaining to IVLBCL and HLH are reviewed."

We previously observed that in such comorbidity settings, macrophages exhibit impaired efferocytosis and reduced anti-inflammatory polarization. In this study, we investigated whether simultaneously restoring these two defective macrophage functions could provide a unified therapeutic strategy both for hepatic and vascular pathology. To establish a comorbidity model featuring concurrent hepatic steatosis and atherosclerosis, we fed ApoE-/-mice a high-fat diet for 14\u00a0weeks. Moreover, we engineered bone marrow-derived macrophages to co-overexpress TGF\u03b21 and MerTK (M\u03c6Smart), thereby restoring anti-inflammatory properties and phagocytic capacity, then treated mice with control macrophages or M\u03c6Smart. TGF\u03b21 and MerTK overexpression in macrophages reprogrammed these cells toward an anti-inflammatory phenotype and endowed them with strong phagocytic capacity under lipid-loaded conditions. M\u03c6Smart reprogrammed macrophage injection into ApoE-/- mice alleviated inflammation locally in the plaque and liver. Consistent with the reduced inflammation, plaques became smaller and more stable after the adoptive transfer of reprogrammed macrophages. Mechanistically, the reprogrammed macrophages alleviated disease manifestations not only via direct inhibition of plaque inflammation but also by reshaping the inflammatory condition in the liver and plaque, where the transferred M\u03c6Smart predominantly accumulated. Macrophage-targeted dual-gene therapy overcomes the limitations of single-target approaches and achieves simultaneous therapeutic efficacy both in the liver and vasculature, establishing a preclinical proof-of-concept for multi-gene synergistic cell therapy in cardiometabolic disease."

Here, we investigated macrophage sensing of Debaryomyces hansenii, a food-derived yeast that we found to be enriched within intestinal ulcers of Crohn disease (CD) patients. Using a cell surface receptor antibody screen of bone marrow-derived macrophages infected with a CD patient isolate of D. hansenii, we showed that D. hansenii-induced macrophage activation characterized by increased expression of co-stimulatory molecules, MHC-II, and pattern recognition receptors, including the C-type lectin receptor Dectin-1. Antibody blockade experiments showed both Dectin-1 and complement receptor 3 subunit CD11b were required for phagocytosis of D. hansenii, while Dectin-1 was uniquely required for production of the pro-inflammatory cytokine tumor necrosis factor (Tnf). CRISPR-Cas9-mediated deletion of Dectin-1 phenocopied antibody neutralization effects on phagocytosis. Furthermore, deletion of Dectin-1 or its downstream signaling adaptor molecule Card9 resulted in reduced Tnf secretion in response to D. hansenii. Dectin-1-mediated uptake of D. hansenii was observed in primary bone marrow-derived macrophage and dendritic cells, as well as across the spectrum of macrophage polarization states. Together, these findings define the role of Dectin-1-Card9 signaling axis in innate immune cell sensing of D. hansenii.

Their functional plasticity is closely regulated by metabolic reprogramming, particularly glucose metabolism. Glucose-related pathways, including glycolysis, gluconeogenesis, the pentose phosphate pathway, glycogen metabolism, and pyruvate/lactate metabolism, influence TAM polarization, cytokine production, phagocytosis, antigen presentation, and T cell interactions. In many tumors, enhanced glycolysis and lactate accumulation promote M2-like TAM polarization and suppress CD8+ T cell activity, whereas certain metabolic programs may support M1-like anti-tumor functions under specific conditions. This mini review summarizes major glucose metabolic pathways involved in TAM regulation, highlights their context-dependent pro- and anti-tumor roles, and discusses therapeutic strategies for reprogramming TAM metabolism to improve anti-tumor immunity and immunotherapy response."

Here, we demonstrate that non-invasive and localizable pulsed electromagnetic fields (PEMFs) induce macrophage reprogramming downstream of transient receptor potential canonical 1 (TRPC1) channel activation. Brief (10\u00a0min) PEMF exposure polarized macrophages toward an M1 phenotype by activating Stimulator of Interferon Genes (STING)-dependent NF-\u03baB inflammatory pathways that were abolished by TRPC1 knockdown or inhibition. PEMF exposure directly enhanced the immunogenicity of breast cancer cells and modified macrophage-cancer crosstalk to promote M1 macrophage polarization and the attraction of STING-activated macrophages to the cancer cells. In co-cultures, PEMF exposure stimulated macrophage-mediated phagocytosis of cancer cells in a STING- and TRPC1-dependent manner. In spheroids, PEMFs induced the reprogramming of TAMs to an M1 status and selectively enhanced infiltration of M1 macrophages, resulting in STING-mediated phagocytosis of cancer cells. In mice, 2\u00a0weeks of twice-weekly PEMF exposure resorbed engrafted tumors and selectively eliminated cancer cells within tumors while promoting immune cell recruitment. PEMFs offer a non-invasive manner to locally reprogram TAMs within the tumor microenvironment to preferentially eliminate cancer cells."

Reduced NLRC5 expression is associated with a poor prognosis for many types of cancers. Previously, we showed that mice with a myeloid-specific deletion of Nlrc5 (Nlrc5m\u00f8-KO) develop gastric lymphoid lesions to Helicobacter infection resembling early-stage marginal zone lymphoma. We hypothesized that NLRC5 deficiency may promote a tumor-permissive microenvironment mediated by tumor-associated macrophages (TAMs). Consistent with this hypothesis, splenic macrophages from Helicobacter-infected Nlrc5m\u00f8-KO mice had upregulated expression of genes encoding the TAM receptor tyrosine kinases, Axl and Mertk. The levels of AXL and MERTK gene expression and MERTK phosphorylation were increased in NLRC5-/- THP-1 macrophages when compared with WT cells. In response to Helicobacter stimulation, Nlrc5-/- macrophages had significantly elevated anti-inflammatory responses (IL-10, TGF-\u03b2, Socs1, Socs3) compared with WT cells. Importantly, Nlrc5-/-macrophages showed enhanced efferocytosis and reduced antigen presentation to CD8+ T cells. Pretreatment of macrophages with AXL and MERTK inhibitors (R428, UNC2025) resulted in reduced efferocytosis and phosphorylation of downstream signaling molecules, STAT3 and ERK1/2. We propose that defective NLRC5 signaling in macrophages leads to tumor-permissive responses, thereby promoting the development of gastric lymphoid neogenesis to Helicobacter infection."

Data were processed with Z-score normalization, variance thresholding and PCA (45 principal components). Five classifiers were constructed: LR, linear SVM, RF, XGBoost and LightGBM. Model stability and performance were assessed by 5-fold stratified cross-validation and independent test validation. The 45 principal components accounted for 99.92% of cumulative variance. LR showed optimal performance, with a test AUC of 0.9821, classification accuracy of 84.62%, and a mean cross-validation AUC of 0.9606 (95% CI: 0.8887-0.9895).

These localized microenvironments are shaped by factors such as nutrient availability, hypoxia, acidosis, and immunomodulatory metabolites, all of which strongly influence CD8\u207a T cell infiltration, migration, persistence, and effector function. Growing evidence indicates that spatial metabolic heterogeneity contributes to immune exclusion, T cell dysfunction, and resistance to immunotherapy. This has been accompanied by major advances in spatial metabolomics, particularly mass spectrometry imaging, which now enable the in situ mapping of metabolites within intact tissues. Combined with transcriptomic, proteomic, and imaging-based approaches, these technologies provide unprecedented insight into how metabolism is organized across tumors and how it shapes tumor-immune interactions. In this review, we discuss how metabolic zonation shapes CD8\u207a T cell function across primary tumors and metastatic lesions. We highlight emerging evidence linking localized metabolic programs to T cell exhaustion, impaired motility, and altered immune composition, and discuss therapeutic strategies aimed at improving T cell metabolic fitness, including metabolic modulation and engineering approaches relevant to immune checkpoint blockade and adoptive cell therapies. Finally, we consider the translational potential of spatial metabolomics for biomarker discovery and the development of precision immunometabolic oncology."

Free-text MRI reports may describe the primary tumor but may inconsistently document key management-relevant findings, including mesorectal fascia and circumferential resection margin status, depth of extramural spread, extramural vascular invasion, lateral pelvic lymph nodes, and low rectal sphincter complex involvement. This retrospective audit assessed whether use of a structured MRI reporting template was associated with improved completeness of primary rectal cancer staging reports. This retrospective audit included 60 pelvic MRI reports performed for suspected or biopsy-proven primary rectal carcinoma at a tertiary care radiology department. Thirty consecutive reports prepared before template implementation were assigned to the free-text reporting group, and 30 reports prepared after template implementation were assigned to the structured reporting group. Reports were assessed using a predefined checklist of essential MRI staging elements, including tumor location, distance from the anal verge, craniocaudal tumor length, circumferential tumor position, relationship to the anorectal junction and anterior peritoneal reflection, MRI T category, depth of extramural spread, mesorectal fascia/circumferential resection margin status, extramural vascular invasion, mesorectal nodes, tumor deposits, lateral pelvic lymph nodes, sphincter complex involvement, levator ani involvement, adjacent organ invasion, and final MRI-based risk summary.

No formal statistical hypothesis testing was performed; therefore, these findings should be interpreted descriptively rather than inferentially. Implementation of a structured MRI reporting template was associated with higher report completeness in this descriptive retrospective audit of primary rectal cancer staging reports. The structured template was associated with more complete documentation of clinically relevant reporting elements, particularly margin status, extramural spread, extramural vascular invasion, lateral pelvic nodes, and low rectal sphincter complex involvement.

This comprehensive narrative review synthesizes the evidence for newly approved and emerging pharmacotherapies for MASH, addressing the mechanisms of action, pivotal clinical trial data, efficacy, safety profiles, and place in therapy for resmetirom and semaglutide. It also discusses key agents including pioglitazone, saroglitazar, and vitamin E, and evaluates the non-invasive testing (NIT) toolkit-including FIB-4, VCTE, shear wave elastography, MRE, and ELF-in the context of a structured, risk-stratified clinical algorithm. Resmetirom (Rezdiffra), a THR-\u03b2 agonist, achieved MASH resolution in 26%-30% versus 10% placebo and fibrosis improvement in 24%-26% versus 14% placebo at 52 weeks in the MAESTRO-NASH trial. Semaglutide 2.4 mg (Wegovy) demonstrated a 28.7% delta over placebo in MASH resolution in the ESSENCE trial. Pioglitazone has additional evidence for reducing the FIB-4 index in real-world studies. Saroglitazar, a PPAR-\u03b1/\u03b3 dual agonist approved in India, has shown significant reductions in ALT, liver fat, and metabolic parameters in Phase 2 studies and is advancing to Phase 2b. Shear wave elastography is a clinically important alternative to VCTE for fibrosis staging, particularly in patients with obesity, and offers value in resolving discordant FIB-4/VCTE results. The approval of resmetirom and semaglutide marks a new era in MASH management. A risk-stratified algorithmic approach using NITs guides patient selection, with liver biopsy reserved for specific clinical scenarios. The therapeutic landscape is rapidly evolving, with saroglitazar and combination approaches representing key frontiers."

However, its spatial resolution is limited by acoustic diffraction, and incomplete detection geometry can substantially degrade image fidelity and quantitative accuracy. Here, we present a ULM-guided model-based reconstruction framework, termed 3D-PAULMprior that incorporates sub-diffraction vascular priors from concurrent ultrasound localization microscopy (ULM) into 3D photoacoustic reconstruction. The method uses weighted regional Laplacian regularization to integrate high-resolution vascular information into the inverse problem, thereby enhancing vascular sharpness, suppressing limited-view artifacts, and improving blood oxygen saturation estimation. We validated 3D-PAULMprior using numerical simulations, tissue-mimicking phantoms, and in vivo mouse brain imaging. Compared with conventional reconstruction, 3D-PAULMprior reduced the system blurring, increased contrast-to-noise ratio, and enhanced structural similarity. In vivo, 3D-PAULMprior enhanced the delineation of the vascular structures that were poorly resolved in conventional reconstructions and produced more spatially confined sO\u2082 maps. These results establish 3D-PAULMprior as a robust multimodal reconstruction strategy for high-resolution structural and functional photoacoustic imaging."

We present a DiceCT-based digital atlas of a human hand from a consented female donor through the University of Missouri Gift of Body program, scanned at 48.8\u2009\u03bcm resolution following Lugol's iodine staining. Bones, tendons, intrinsic muscles, neurovascular structures, the flexor retinaculum and carpal tunnel, and dorsal digital expansions were manually segmented to generate labeled multiplanar sections and three-dimensional reconstructions. The dataset resolves epidermal ridge detail on the palmar surface while capturing structures, including the carpal tunnel contents, extensor mechanism, neurovasculature, palmar fat pads, and metacarpophalangeal sesamoids. Reconstructions demonstrate relevant relationships among the median nerve, flexor tendons, and flexor retinaculum, the ulnar nerve within Guyon's canal and the radial artery within the anatomical snuffbox. Distal digital arterial anastomoses are visible near the terminal tufts, and radial artery branches supplying the dorsal and distal scaphoid poles provide context for scaphoid vascular vulnerability. Muscle volumes and physiological cross-sectional areas were calculated using all fascicles within each intrinsic muscle. Flexor pollicis brevis and adductor pollicis exhibited comparatively large relative physiological cross-sectional areas, whereas the lumbricals had the smallest values, consistent with previous architectural estimates. By documenting whole-hand anatomy and within-individual muscle architecture non-destructively, this atlas provides a high-fidelity resource for anatomical education, documentation of anatomical variation, clinical interpretation, and generation of anatomically consistent biomechanical models. These results support DiceCT as a platform bridging anatomical research, clinical translation, and pedagogical access to donor-specific human anatomy."

However, image quality is often compromised in the half-detector (HD) geometry, where data truncation arising from the offset detector configuration coexists with metal artifacts caused by metallic implants. These artifacts interact synergistically, leading to severe image degradation that conventional correction methods fail to\u00a0address. We propose a multi-stage deep learning framework, HD-TMAR, to systematically decompose and correct combined truncation and metal artifacts in HD CBCT. The proposed framework adopts a multi-stage restoration strategy comprising three stages: (1) Sinogram Correction, which explicitly isolates the artifact residuals from the projection data and synergizes them with structural prior-normalized features to systematically suppress global truncation biases and metal artifacts; (2) Merging and Reconstruction, which employs a specialized overlapping patching and selective replacement strategy to accurately reconstruct the truncated regions and metal traces; and (3) Image Refinement, where ImgNet further enhances the reconstructed image to restore fine anatomical\u00a0textures. Experiments using realistic simulation datasets demonstrated that the proposed method achieved the highest qualitative fidelity and quantitative metrics compared to previous deep learning MAR methods. The framework effectively suppressed severe artifacts while preserving dental morphology, whereas comparative methods suffered from secondary artifacts or\u00a0blurring. HD-TMAR successfully disentangles complex artifact interactions. By synergizing sinogram-domain correction with image-domain refinement, the framework demonstrates promising potential for clinical application in enhancing the diagnostic performance of HD CBCT systems in the presence of metallic\u00a0implants."

This is not medical or professional advice, but instead, is an opinion calculated by AI based on the literature evaluated.\n\n###[CLAIM EVALUATED AND ANSWER TO USER]\n\"Restoration of efferocytosis is highly dependent on macrophage polarization states; M1 and M2 phenotypes can both contribute to resolution if metabolic cues are corrected.\"\n\n### [ABSTRACT & REWRITTEN CLAIM]\nScientific investigation into the restoration of efferocytic efficiency indicates that while M1 and M2 classifications serve as historical proxies for macrophage function, the actual capacity for apoptotic cell clearance is contingent upon metabolic and signaling status rather than a fixed phenotypic designation. Evidence supports that modulation of specific pathways (e.g., A2AR, MerTK, JAK/STAT, and mitochondrial metabolism) can enhance efferocytosis across diverse states.\n\n### [INTRODUCTION & JUSTIFICATION]\nThe paradigm of macrophage polarization as a binary M1/M2 system is increasingly superseded by the recognition of a functional continuum dictated by metabolic plasticity. Efferocytosis is an energy-demanding process that requires specific signaling cues, such as those initiated by IL-33 or Gas-6, and metabolic support, such as HIF1\u03b1-dependent glycolysis. While inflammation-associated (M1-like) macrophages are traditionally viewed as pro-inflammatory, evidence demonstrates that they can be reprogrammed to exhibit enhanced efferocytosis through targeted interventions. For instance, A2AR activation promotes efferocytosis to accelerate repair, and the induction of specific receptors like MerTK allows for the efficient engulfment of debris, bridging the gap between pro-inflammatory states and the resolution of inflammation.\n\n### [DISCUSSION: NOVEL & OVERLOOKED]\n* Efferocytosis acts as a primary resolution driver that can be pharmacologically bolstered, even in chronic inflammatory states, through the activation of specific ion channels like Piezo1.\n* Metabolic sensors like A2AR link microenvironmental triggers to the cellular machinery required for myelin and apoptotic cell clearance.\n* The expression of CD3 on macrophages, traditionally a T-cell marker, suggests a previously uncharacterized layer of complexity in how myeloid cells integrate signaling pathways during stress.\n* Natural polysaccharides show potential in metabolic regulation of macrophages, influencing polarization and inflammatory output through the modulation of pathways like NF-\u03baB and MAPK.\n* Circulating cochlin LCCL domain serves as an exogenous efferocytosis-promoting factor, highlighting the role of systemic serum proteins in local tissue repair.\n* Fetal sex significantly shapes maternal monocyte metabolic programming, with pEVs inducing sex-dependent shifts in efferocytic activity.\n* Non-functional isoforms of P2X7 in cancer cells reveal how malignant cells bypass the regulated scavenger receptor pathways typically used by macrophages.\n\n### [EVIDENCE, METHODOLOGY & CITATIONS]\n1.

Single-cell RNA-seq (ScRNAseq) of the peritoneal macrophages from EMS patient revealed elevated Triggering Receptor Expressed on Myeloid cells 2 (TREM2) and signal regulatory protein \u03b1 (SIRP\u03b1). The expression of TREM2 and SIRPa is positively correlated, and each are positively correlated with estrogen response. Mouse EMS model was established by intraperitoneal injection of estrogen primed mouse endometrial fragments into recipient female mice. In vitro estrogen treatment of RAW 264.7 cells indicated an increasing TREM2/SIRP\u03b1 expression and enhancing phagocytosis of lesion cells derived from WT EMS ectopic lesions. Peritoneal macrophage from mice with EMS were analyzed using flow cytometry for the expression of TREM2 and SIRP\u03b1. The assessment of F4/80, CD206, and SIRP\u03b1 expressing cells within the lesions were performed through the implementation of multi-color immunohistochemistry (mIHC). Small peritoneal macrophages (SpMs, F4/80low CD11blow) were markedly increased in the EMS model. Trem2 knockout mice, as the recipient, showed smaller ectopic lesion size and less lesion formation. TREM2 deficiency inhibited SpM polarization into M2 and downregulated their SIRP\u03b1 expression, while enhancing phagocytic activity. Mechanistically, estrogen pretreatment upregulated TREM2, which correlated with SIRP\u03b1 upregulation and impaired phagocytosis. Under estrogen exposure, TREM2 knockdown RAW 264.7 cells potentiated phagocytosis. Thus, TREM2 is an important contributing pathogenic factor in promoting EMS by enhancing M2 polarization and suppressing phagocytosis via SIRP\u03b1 upregulation.\n\nID: 42550891\nTitle: Adenosine 2A receptor drives microglial efferocytosis to accelerate white matter repair and functional recovery after stroke.\nAbstract: Although reperfusion therapy effectively restores blood flow to occluded brain arteries after ischemic stroke, many patients develop persistent white matter injury, a major contributor to long-term neurological disability. Currently, there are few approved clinical therapies that specifically target white matter repair to enhance functional recovery after stroke. We demonstrated that microglial adenosine 2A receptor (A2AR) is essential for spontaneous white matter regeneration after ischemic injury in mice. Deletion of A2AR in microglia specifically impaired chronic-phase repair without altering the severity of acute ischemic injury. Pharmacological activation of A2AR signaling with blood-brain barrier-permeable agonistic micelles during the early reperfusion phase enhanced white matter structural repair and led to sustained improvements in cognitive and sensorimotor function in mice. Mechanistically, A2AR activation promoted microglial efferocytosis of apoptotic cells and myelin debris in the lesioned white matter, thereby limiting secondary necrosis-induced inflammation, enhancing neurotrophic factor release, and establishing a reparative microenvironment conducive to oligodendrocyte precursor cell differentiation and remyelination. Moreover, A2AR signaling engaged HIF1\u03b1-dependent metabolic reprogramming to increase glycolysis, thereby providing the energetic support required for efficient and sustained efferocytosis. Together, these findings identify A2AR as a critical regulator of microglia-mediated white matter repair and a promising therapeutic target for enhancing regeneration after stroke.\n\nID: 42549352\nTitle: Magnetic Reprogramming of Macrophages Stimulates Phagocytosis of Breast Cancer Cells via a TRPC1-STING Inflammatory Axis.\nAbstract: The reprogramming of tumor-associated macrophages (TAMs) from a pro-tumoral M2 to an anti-tumoral M1 phenotype is an attractive therapeutic strategy whose clinical translation is undermined by the systemic toxicity of currently available pharmacological approaches. Here, we demonstrate that non-invasive and localizable pulsed electromagnetic fields (PEMFs) induce macrophage reprogramming downstream of transient receptor potential canonical 1 (TRPC1) channel activation. Brief (10\u00a0min) PEMF exposure polarized macrophages toward an M1 phenotype by activating Stimulator of Interferon Genes (STING)-dependent NF-\u03baB inflammatory pathways that were abolished by TRPC1 knockdown or inhibition. PEMF exposure directly enhanced the immunogenicity of breast cancer cells and modified macrophage-cancer crosstalk to promote M1 macrophage polarization and the attraction of STING-activated macrophages to the cancer cells. In co-cultures, PEMF exposure stimulated macrophage-mediated phagocytosis of cancer cells in a STING- and TRPC1-dependent manner. In spheroids, PEMFs induced the reprogramming of TAMs to an M1 status and selectively enhanced infiltration of M1 macrophages, resulting in STING-mediated phagocytosis of cancer cells. In mice, 2\u00a0weeks of twice-weekly PEMF exposure resorbed engrafted tumors and selectively eliminated cancer cells within tumors while promoting immune cell recruitment. PEMFs offer a non-invasive manner to locally reprogram TAMs within the tumor microenvironment to preferentially eliminate cancer cells.\n\nID: 42539101\nTitle: An immune-stimulating antibody conjugate spatiotemporally targeting CD47 and TLR9 elicits macrophage-dependent tumor clearance and durable anti-cancer adaptive immunity.\nAbstract: Cluster of differentiation 47 (CD47) blockade promotes tumor cell phagocytosis; however, transitioning this initial innate immune event into durable anti-cancer adaptive immunity and tumor control remains a critical challenge. To address this translational gap, we have engineered aCD47 - CpG, a novel immune-stimulating antibody conjugate (ISAC) coupling a CD47-blocking antibody (aCD47) to a Toll-like receptor 9 agonist, unmethylated CpG, to enable synchronized deployment of co-stimulatory signals during tumor engulfment. This ISAC, aCD47-CpG, but not the parent aCD47, reprograms macrophages toward an anti-tumor M1-like phenotype, enhances antigen cross-presentation, and promotes robust CD8 + T cell priming. We found that systemically administered aCD47-CpG drove macrophage-dependent tumor suppression in a human lymphoma xenograft model. In parallel, the treatment in immunocompetent syngeneic models of lymphoma and highly immunosuppressive triple-negative breast cancer resulted in profound tumor regression, metastasis inhibition, and durable anti-cancer immune memory. These effects were accompanied by remodeling of the immunosuppressive tumor microenvironment toward an immune-permissive state, characterized by M2-to-M1 macrophage repolarization, intratumoral infiltration of cytotoxic and memory T cells, and depletion of regulatory T cells. This spatiotemporally coordinated immunotherapy platform offers a promising strategy to bridge innate and adaptive immunity, thereby advancing the translational potential of CD47-targeted cancer therapies.\n\nID: 42536041\nTitle: Quorum-Sensing Signal Molecule C10-HSL Exhibits a Cross-Kingdom Inhibition Effect on Phytophthora sojae.\nAbstract: AHL quorum sensing signal molecules of bacteria are involved in regulating the inhibition effect of biocontrol agents on several plant diseases. However, the direct inhibition effect of AHL on pathogens and the molecular mechanism of inhibition remain unclear. Phytophthora root rot of soybean (PRR), caused by Phytophthora sojae, is a devastating oomycete disease in soybean production. To investigate the application potential of AHL in the PRR control, zoospore chemotaxis, oospore formation, mycelial growth, and pathogenicity in P. sojae responding to AHL were determined. The transcriptome of P. sojae in response to AHL was also analyzed. The key differentially expressed genes (DEGs) were quantitatively verified by qRT-PCR. We found that C10-HSL was the most abundant AHL in the fermentation broth biocontrol strain Pseudomonas mandelii. C10-HSL repels P. sojae zoospores, inhibits P. sojae mycelial growth and oospores formation, and alleviates the pathogenicity of P. sojae. The inhibition effect was regulated mainly by nitrogen metabolism, efferocytosis, glycolysis/gluconeogenesis, carbon metabolism pathways. P. sojae cell structures could disrupt and carbohydrate utilization could interfere during the response process. This result reveals that C10-HSL acts as a cross-kingdom signaling molecule to inhibit P. sojae and control PRR.\n\nID: 42535709\nTitle: Macrophage efferocytosis in pregnancy and pregnancy complications.\nAbstract: Efferocytosis is a vital process during early placental development, which removes apoptotic cells generated through decidualisation and controls inflammation. As pregnancy progresses and levels of apoptotic placental cells increase, macrophage efferocytosis remains essential to maintain a healthy pregnancy. There is mounting evidence that dysfunctional macrophage efferocytosis is implicated in the pathogenesis of multiple pregnancy complications. This includes disorders of malplacentation such as preeclampsia and fetal growth restriction, wherein impaired spiral artery remodelling and inflammation in the decidua impairs placental vascularisation leading to maternal hypertension, or impaired fetal growth. As a shift in macrophage phenotype and cytokine secretion is required for the onset of labour, alterations in phenotype earlier in pregnancy may be associated with preterm birth. In more rare pregnancy complications such as chronic histiocytic intervillositis (CHI), impaired efferocytosis and wound healing by infiltrating intervillous macrophages may contribute to their excessive recruitment into the intervillous space, hindering placental function. In this review, we describe the importance of efferocytosis by various maternal macrophage populations in the placenta and review the evidence of how impaired efferocytosis contributes to pathology. Furthermore, therapeutic targeting of macrophage efferocytosis and how this may be used to prevent or treat obstetric conditions is explored.\n\nID: 42535557\nTitle: Role of Lipin-1 in Macrophage-Mediated Atherosclerosis: Is It Atherogenic or Atheroprotective?\nAbstract: Macrophages are central regulators of atherosclerosis, governing lipid accumulation, inflammatory signaling, and plaque stability. Lipin-1 is a multifunctional lipid-metabolic regulator that integrates cellular metabolism with inflammatory responses through its dual roles as a phosphatidic acid phosphatase enzyme and a transcriptional coregulator. However, its role in macrophage-driven atherosclerosis remains controversial. This review critically evaluates the domain-specific functions of lipin-1 and their impact on disease progression. Accumulating evidence indicates that lipin-1 exerts divergent, domain-dependent effects. The transcriptional coregulatory activity of lipin-1 promotes peroxisome proliferator-activated receptor/peroxisome proliferator-activated receptor \u03b3 coactivator 1-\u03b1 signaling, enhances fatty acid \u03b2-oxidation and oxidative phosphorylation, and supports interleukin-4-driven proresolving macrophage polarization. It also enhances efferocytosis, suppresses sterol regulatory element-binding protein-mediated lipogenesis, and reduces oxidized low-density lipoprotein-induced foam-cell formation. These effects are associated with reduced necrotic core formation, lower interleukin-23 signaling, diminished macrophage necroptosis, and improved plaque stability in experimental models. In contrast, the phosphatidic acid phosphatase enzymatic activity of lipin-1 activates diacylglycerol-dependent protein kinase C-extracellular signal-regulated kinase- activator protein-1 and toll-like receptor 4 signaling, promotes inflammatory eicosanoid production, enhances oxidized low-density lipoprotein uptake, impairs cholesterol efflux, and accelerates foam-cell formation and vascular inflammation. Myeloid-specific loss of phosphatidic acid phosphatase activity reduces lesion size and inflammatory burden while improving macrophage lipid handling. Collectively, current evidence supports a domain- and context-dependent role for lipin-1 in atherosclerosis. The transcriptional coregulatory function appears predominantly atheroprotective, whereas phosphatidic acid phosphatase enzymatic activity is proinflammatory and atherogenic. Selective modulation of lipin-1 activity in macrophages may therefore represent a promising therapeutic strategy to limit atherosclerosis progression while preserving inflammation-resolving pathways.\n\nID: 42535315\nTitle: AIEgen-Based Biomimetic Nanoplatform for Targeted Synergistic Sonodynamic Therapy and Macrophage Reprogramming of Hyperhomocysteinemic Atherosclerosis.\nAbstract: The instability and subsequent rupture of atherosclerotic plaques are driven primarily by the progressive enlargement of the lipid-rich necrotic cores coupled with local macrophage dysfunction, which readily trigger life-threatening acute cardiovascular and cerebrovascular events. Homocysteine serves as an independent risk factor for atherosclerosis. Here, we developed a synergistic nanotherapeutic strategy for hyperhomocysteinemic atherosclerosis (HHcy-AS) by simultaneously targeting foam cells and diseased macrophages. Specifically, an aggregation-induced emission (AIE) sonosensitizer TTPY-COOH was encapsulated into OPN antibody-modified polymer nanoparticles to form TP-Ab cores, which were then co-loaded with dexamethasone into ROS-responsive platelet membrane-liposome hybrid vesicles, yielding the final nanodrug TP-Ab/Dex@PL. Following intravenous injection, this nanoplatform utilizes platelet membranes to precisely target atherosclerotic plaques, where it rapidly disassembles within the high ROS environments. The released TP-Ab cores selectively deliver TTPY-COOH to foam cells via specific antibody recognition, where subsequent ultrasound-triggered sonodynamic therapy induces cellular apoptosis. Meanwhile, locally released dexamethasone exhibits a robust anti-inflammatory effect and reprograms M1 macrophages into the M2 phenotype, enhancing their efferocytosis for apoptotic foam cells. In an HHcy-AS mouse model, TP-Ab/Dex@PL treatment significantly reduced plaque burden and improved plaque stability. This multifunctional nanoplatform integrates sonodynamic therapy, anti-inflammatory effects, and macrophage reprogramming, offering\u00a0potential\u00a0for the precise clinical treatment of atherosclerosis.\n\nID: 42530332\nTitle: Islet-Resident Macrophages as Dynamic Immunometabolic Integrators of \u03b2-Cell Fate in Health and Diabetes.\nAbstract: Islet-resident macrophages (IRMs) have emerged as important regulators of pancreatic islet biology, operating at the intersection of metabolism and immunity. Beyond their classical roles as immune sentinels, accumulating evidence indicates that IRMs dynamically integrate \u03b2-cell activity, environmental cues, and metabolic stress, thereby coordinating islet homeostasis, adaptive remodelling, and disease progression. However, their context-dependent functions and therapeutic potential remain incompletely understood. This review summarizes current evidence regarding IRM origins, phenotype, metabolic plasticity, and bidirectional crosstalk with \u03b2 cells in health, type 1 diabetes, and type 2 diabetes. We further review emerging therapeutic concepts targeting macrophage metabolism, intercellular communication, and organelle function, while discussing current challenges in translating findings from murine IRMs to human disease. Under physiological conditions, IRMs maintain islet integrity through surveillance, efferocytosis, trophic signalling, redox control, and maintenance of intercellular communication within the islet niche. In diabetes, chronic glucolipotoxicity, autoimmunity, oxidative stress, and amyloid-associated injury can redirect these homeostatic programs toward maladaptive inflammatory states that impair insulin secretion and accelerate \u03b2-cell loss. Collectively, these findings support a unified framework in which IRMs act as immunometabolic hubs integrating local and systemic signals to determine \u03b2-cell fate. IRMs represent central immunometabolic hubs that orchestrate \u03b2-cell fate during health and diabetes. Emerging therapeutic strategies targeting macrophage metabolism, intercellular communication, and organelle function may help prioritize future mechanistic studies and guide safer macrophage-centered interventions for diabetes.\n\nID: 42527031\nTitle: CXCR2-mediated metabolic interaction between prostate cancer cells and the immunosuppressive tumor microenvironment.\nAbstract: Neuroendocrine prostate cancer (NEPC) is characterized by strong immune evasion and profound metabolic reprogramming. A high regulatory T cell (Treg)/CD8+ T cell ratio and an increased proportion of M2/M1 tumor-associated macrophages (TAMs) in the NEPC tumor microenvironment (TME) are associated with poorer progression-free survival, a phenomenon linked to lipid accumulation within the TME. Understanding the regulatory mechanisms governing both the metabolic and immune landscapes of NEPC is critical. To investigate these mechanisms, prostate cancer cell lines and patient samples were analyzed using immunohistochemistry, flow cytometry, PCR, western blotting, and mass spectrometry. The interleukin (IL)-8/CXCR2 signaling pathway was targeted for intervention in two tumor-bearing mouse models. Data revealed that IL-8/CXCR2 signaling drives the accumulation of free fatty acids and very-long-chain polyunsaturated fatty acids, leading to ferroptosis in tumor-infiltrating CD8+ T cells. This, in turn, promotes Treg cell infiltration and an M2 macrophage-dominant immune landscape. Mechanistically, IL-8/CXCR2 signaling upregulates the AKT-mTOR-FAS pathway while activating the mTOR-MYC-ELOVL5 axis via Rictor acetylation. In preclinical studies using NSG and B57BL/6 mouse models, CXCR2 inhibition restored CD8+ T cell antitumor activity and enhanced TAM phagocytosis, significantly reducing tumor growth. These findings highlight CXCR2 as a promising immunotherapeutic target for NEPC and underscore its relevance in translational medicine.\n\nID: 42523480\nTitle: Reduced LACTB expression in myeloid cells is associated with elevated succinylcarnitine and reduced Alzheimer's disease risk.\nAbstract: Lactamase \u03b2 (LACTB) is a serine \u03b2-lactamase-like mitochondrial enzyme genetically associated with obesity, kidney disease, and hyperlipidemia. LACTB is located in an Alzheimer's Disease (AD) risk locus and its expression in the brain has been genetically associated with AD susceptibility. The aim of this study was to investigate LACTB function and genetic link to AD in myeloid cells, due to their central role in modulating AD risk. Our Mendelian randomization analyses revealed that lower LACTB expression in myeloid cells is genetically associated with reduced disease susceptibility and increased succinylcarnitine, a metabolite independently associated with AD risk. We identified LACTB as a primary enzyme responsible for succinylcarnitine hydrolysis. In human macrophages and microglia, LACTB loss promoted enhanced oxidative phosphorylation, reduced protein synthesis and altered lipid homeostasis. LACTB expression was upregulated following interferon or TNF stimulation, and LACTB loss modified efferocytosis-related functions under inflammatory conditions. In vivo, xenotransplanted human LACTB knockout microglia showed enhanced association with amyloid plaques in the mouse brain. Together, these findings experimentally validated the genetic association between reduced LACTB expression and elevated succinylcarnitine and identified LACTB as an inflammation-responsive regulator of myeloid cell metabolism and function that may contribute to its protective genetic association with AD. Given its druggability and potential to use succinylcarnitine as a genetically-validated endophenotype and target engagement biomarker, LACTB represents a promising therapeutic target for AD.\n\nID: 42522926\nTitle: Notoginsenoside R1 Alleviates Macrophage Inflammatory Responses via Modulating the JAK1/STAT3 Pathway.\nAbstract: Notoginsenoside R1 (NR1), an active component of Panax notoginseng, may exert anti-atherosclerotic effects by modulating macrophage M1/M2 polarization. This study aimed to investigate the specific mechanism of NR1 against atherosclerosis based on the JAK1/STAT3 pathway. M1 and M2 macrophage models, as well as an ox-LDL-induced macrophage model, were established. These models were treated with varying concentrations of NR1. Our results demonstrated that NR1 effectively suppressed LPS/IFN-\u03b3 or ox-LDL-induced polarization of macrophages toward the pro-inflammatory M1 phenotype and promoted their transition to the anti-inflammatory M2 phenotype. Concurrently, NR1 significantly inhibited the phagocytosis of ox-LDL by macrophages in the atherosclerosis model, reduced lipid accumulation, and improved mitochondrial function. Mechanistically, the regulatory effects of NR1 on macrophage polarization and function primarily depended on the inhibition of the JAK1/STAT3 signaling pathway. In conclusion, this study suggests that NR1 targets the JAK1/STAT3 pathway to balance macrophage M1/M2 polarization, thereby suppressing inflammatory responses, and ultimately alleviating atherosclerosis.\n\nID: 42520678\nTitle: Dual role of macrophage heterogeneity in allergic inflammation: from mechanism to targeted therapy.\nAbstract: Allergic inflammation, such as allergic asthma, allergic rhinitis, and atopic dermatitis, shares many pathogenic hallmarks, including inappropriate activation of type 2 immune responses, tissue barrier dysfunction, and disruption of local homeostasis. Due to their remarkable plasticity and tissue adaptability, macrophages are crucial effector cells of the innate immune system that play complex, context-dependent dual roles in allergic inflammation. On the one hand, macrophages are implicated in the persistence of chronic inflammation, thereby boosting Th2 cell recruitment, eosinophil infiltration, antigen processing, chemokine secretion, inflammatory mediator release, and tissue remodeling. On the other hand, they promote the resolution of inflammation by triggering barrier repair, producing anti-inflammatory mediators including TGF-\u03b2 and IL-10, and phagocytosing apoptotic cells. Recent single-cell transcriptomic and functional studies have demonstrated that macrophages are dynamically distributed along an activation continuum rather than merely fitting into the traditional M1/M2 polarization. Functional states are determined by cellular origin, illness stage, tissue niche, and complex regulatory networks. For macrophages implicated in airway inflammation and remodeling, non-IgE-dependent nasal neurogenic reflexes, skin barrier disruption, itch neuroimmune circuits, and inflammation resolution, distinct barrier tissues-such as the lung, nasal mucosa, and skin-show notable tissue specificity. The pathogenic and preventive functions of macrophages in allergic inflammation are systematically summarized in this review, which also emphasizes a continuous spectrum of macrophage activation and incorporates interactions among metabolic reprogramming, pyroptosis, epigenetic control, and trained immunity. Given the dynamic and microenvironment-dependent nature of macrophage function, future treatment approaches need to shift from broad anti-inflammatory therapies to precision reprogramming that is stage-specific and tissue-tuned. During the start and amplification stages of inflammation, therapeutic strategies should target pathogenic M2a-like programs, chemokine networks, monocyte recruitment, and excessive pyroptotic responses. On the other hand, M2b/M2c and pro-resolving macrophage-mediated efferocytosis, immunological tolerance, and tissue healing should be the focus of tactics in the resolution and repair stages. Furthermore, the management of allergic diseases may shift from empirical anti-inflammatory therapy to mechanism-guided precision interventions through patient stratification based on single-cell omics, spatial omics, and macrophage-associated biomarkers.\n\nID: 42519318\nTitle: Immunometabolic regulation in gouty arthritis: current evidence, mechanistic insights, and remaining challenges.\nAbstract: Gouty arthritis is driven by monosodium urate (MSU) crystal deposition and acute activation of the NLRP3 inflammasome-IL-1\u03b2 axis. However, crystal burden alone does not fully explain asymptomatic crystal deposition, recurrent flares, or the self-limiting nature of acute inflammation. Immunometabolism provides a useful perspective for understanding these differences. In macrophages, glycolysis supports pro-IL-1\u03b2 expression and inflammatory mediator production, while tricarboxylic acid cycle remodeling, mitochondrial stress, and reactive oxygen species may contribute to inflammasome activation. In neutrophils, glycolysis sustains rapid effector functions, including chemotaxis, degranulation, ROS production, and neutrophil extracellular trap formation. During later stages, efferocytosis, lipid mediator switching, and mitochondrial adaptation may promote inflammation resolution. Systemic metabolic abnormalities may further influence recurrence susceptibility by altering innate immune responsiveness to MSU crystals. This review summarizes current evidence linking immunometabolic pathways to gouty inflammation and discusses remaining questions regarding cell specificity, temporal sequence, causal relevance, and therapeutic translation.\n\nID: 42515167\nTitle: Nrf2 Activation Alleviates Silica-Induced Toxicity in Alveolar Macrophages via Glutamine Metabolic Reprogramming.\nAbstract: As a major occupational hazard, crystalline silica (SiO2) poses a severe risk of pulmonary toxicity. While the irreversible fibrosis of late-stage silicosis has been extensively studied, the cellular and molecular mechanisms by which SiO2 reprograms macrophage metabolism to drive early pathogenesis remain poorly understood. To elucidate this early immune-inflammatory response, we combined targeted metabolomics, pharmacological treatments, and nutrient deprivation in murine alveolar macrophages. Our results demonstrate that SiO2 exposure severely impairs the master antioxidant regulator, nuclear factor erythroid 2-related factor 2 (Nrf2), triggering excessive reactive oxygen species (ROS) accumulation and upregulated glutamine catabolism to drive pro-inflammatory M1 macrophage polarization. We demonstrated that Nrf2 activation with tert-butylhydroquinone (TBHQ) redirected glutamine metabolic flux from pro-inflammatory catabolism to antioxidant anabolism, significantly attenuating SiO2-induced M1 polarization. Conversely, Nrf2 inhibition via ML385 exacerbated the inflammatory response. Furthermore, introducing a glutamine deprivation (-Gln) model revealed that restricting glutamine availability significantly attenuated the ability of Nrf2 to reverse M1 polarization, suggesting that its immune-protective effects largely depend on an intact glutamine metabolic pathway. Ultimately, our findings underscore the severe risks of silica exposure and identify the Nrf2-glutamine metabolic axis as a promising target, providing novel mechanistic insights and a robust basis for \"antioxidant-metabolic\" dual-target interventions in early-stage silicosis.\n\nID: 42511907\nTitle: Reprogramming Inflammatory Macrophages with Specialized Pro-Resolving Lipid Mediators: A Novel Immunotherapeutic Strategy for Asthma.\nAbstract: Asthma is defined as a chronic airway inflammatory disorder with over-activation of the immune system accompanied by the inability to resolve inflammation. SPMs are novel potent lipid mediators that play an important role in maintaining inflammation homeostasis and macrophages' functional plasticity. This review will look into the potential function of SPM-programmed macrophage reprogramming as a novel therapeutic strategy for asthma. Unlike current anti-inflammatory treatments, which only focus on suppressing inflammation, SPMs can actively drive the inflammation resolution phase by promoting efferocytosis and wound healing while maintaining the defense against infection. In experimental asthma animal models, lipoxins, resolvins, protectins, and maresins have been demonstrated to alleviate inflammation and airway hyperresponsiveness, shift macrophages towards pro-resolving phenotypes and thus facilitate the resolution process. Levels of some SPM subclasses were found to be reduced in severe or uncontrolled asthmatics, indicating defective resolution pathways may contribute to asthma persistence. The mechanisms include down-regulation of pro-inflammatory cytokines, alteration of macrophage phenotype, improvement of immune homeostasis in the airway milieu, etc. These molecules have become highly promising therapeutic agents after the development of metabolically stable analogs, receptor-targeted agonists, and an improved delivery system. Multi-omics studies coupled with patient stratification based on biomarkers will potentially help in the future to develop personalized resolution-based therapy, in particular for those steroid-resistant and non-type 2 asthmatics. Nevertheless, the evidence provided so far is mainly preclinical; more challenges in terms of pharmacokinetics, formulation and formulation development, regulatory agency approval, and clinical validation remain and will be overcome through further studies, thus warranting investigation into SPM-mediated strategies for asthma and other chronic inflammatory diseases.\n\nID: 42503313\nTitle: A copper nanoplatform with irreversible electroporation induces cuproptosis via lipid reprogramming and remodels tumor immunity in pancreatic cancer.\nAbstract: Pancreatic ductal adenocarcinoma (PDAC) remains one of the most treatment-refractory malignancies, largely due to its dense stromal architecture and limited intratumoral drug penetration. Here, we developed a hyaluronic acid-modified polypyrrole-copper nanoparticle (PLGA-Cuppy@HA, mCuppy) for copper delivery and irreversible electroporation (IRE)-assisted therapy. To optimize therapeutic performance, copper loading and HA surface modification were systematically tuned, resulting in a formulation with balanced physicochemical properties, efficient CD44-mediated cellular uptake, and favorable biological activity. When combined with IRE, mCuppy exhibited enhanced intratumoral retention, improved 3D spheroid penetration, and increased intracellular uptake, which were associated with IRE-induced membrane permeabilization and improved intratumoral distribution. Mechanistically, integrated transcriptomic and metabolomic analyses revealed that the combination treatment induced profound metabolic reprogramming associated with cuproptosis, including dysregulation of pantothenate/CoA biosynthesis, unsaturated fatty acid metabolism, and glycerolipid metabolism. These alterations were accompanied by lipoylated protein aggregation, lipid droplet accumulation, and mitochondrial dysfunction. Notably, additional analyses of cell death pathways suggested that, while cuproptosis represents a dominant mechanism, apoptosis and lipid metabolism-associated stress responses may also contribute to the overall therapeutic effect. In orthotopic PDAC models, mCuppy combined with IRE achieved marked tumor suppression and promoted antitumor immune remodeling, including dendritic cell maturation, increased CD8+ T-cell infiltration, and M1 macrophage polarization. Together, this study demonstrates that IRE-potentiated copper nano therapy induces metabolic vulnerability, cuproptosis, and immune remodeling in PDAC, providing a promising strategy for stromal-rich pancreatic cancer.\n\nID: 42495969\nTitle: Recent Developments in Macrophages Imbalance and Recurrent Spontaneous Abortion.\nAbstract: Recurrent spontaneous abortion (RSA), defined as two or more consecutive pregnancy losses, remains a significant clinical challenge in reproductive medicine. One of the primary reasons of RSA is abnormal immunological circumstances at the interaction between mother and fetus. Emerging evidence highlights the critical role of immune dysregulation, particularly involving macrophages, in the pathogenesis of RSA. Macrophages, key immune cells in the decidua, exhibit phenotypic plasticity and can polarize into pro-inflammatory M1 or anti-inflammatory M2 subtypes, thereby influencing trophoblast invasion, placental development, and immune tolerance. How the immune system's macrophages balance impacts an embryo's development is therefore essential to study. This review elaborates on the mechanisms by which alterations in transcription factors, signaling pathways, cytokine profiles, epigenetic status, and metabolic reprogramming contribute to pregnancy loss. Such aberrations predominantly drive the polarization shift toward the M1 macrophage phenotype, characterized by an elevated M1/M2 ratio. This imbalance triggers excessive secretion of pro-inflammatory cytokines, impairs trophoblast invasion, and disrupts placental angiogenesis, thereby ultimately inducing adverse pregnancy outcomes and spontaneous abortion. By integrating findings from human studies and animal models, this review aims to provide insights into the immune mechanisms underlying RSA and highlights future research directions for improving clinical outcomes.\n\nID: 42494618\nTitle: Mechanism of Action and Therapeutic Potential of Sulforaphane in Skeletal Muscle Diseases: Molecular Pathways and Precision Medicine.\nAbstract: Sulforaphane (SFN), a bioactive isothiocyanate abundant in cruciferous vegetables, has attracted growing interest as a potential nutraceutical intervention for skeletal muscle disorders. This narrative review synthesizes preclinical and early clinical evidence on the mechanisms and therapeutic applicability of SFN in ICU-acquired weakness, diabetic myopathy, sarcopenia, and exercise-induced muscle damage. SFN modulates skeletal muscle pathophysiology through four interconnected axes: regulation of protein homeostasis via mTOR-associated signaling and suppression of ubiquitin-proteasome-mediated catabolism; upregulation of oxidative stress defenses through Nrf2-driven antioxidant enzyme induction; attenuation of inflammatory networks via NF-\u03baB inhibition and promotion of M2 macrophage polarization; and metabolic reprogramming through AMPK-mediated mitochondrial biogenesis and enhanced insulin sensitivity. Preclinical data suggest preliminary protective effects on respiratory and locomotor muscle; however, clinical translation remains uncertain. Several randomized controlled trials have failed to demonstrate significant effects on Nrf2 target genes or metabolic stress biomarkers, and bioavailability varies markedly across formulations and individuals. Heterogeneous responses across muscle fiber types, an undefined therapeutic window, and interindividual variability in gut microbiota-mediated conversion further complicate clinical application. To address these challenges, we propose a conceptual \"Sulforaphane Precision Medicine Framework\" integrating molecular biomarkers, gut microbiome profiling, and dynamic delivery systems to guide personalized intervention. While SFN shows promise as an adjunctive therapy, standardized formulations, refined patient stratification, and rigorous phase III trials are essential before routine clinical adoption can be recommended.\n\nID: 42488660\nTitle: SIRT3 in post-myocardial infarction macrophage reprogramming: linking mitochondrial fitness to inflammation resolution and repair.\nAbstract: Myocardial infarction (MI) remains a leading cause of cardiovascular mortality worldwide. Despite significant advances in reperfusion strategies and pharmacotherapy, persistent inflammation and adverse ventricular remodeling continue to underlie poor long-term clinical outcomes. Macrophages serve as central orchestrators of post-MI healing, coordinating the clearance of necrotic debris, resolution of inflammation, remodeling of the extracellular matrix, and maturation of the fibrotic scar. However, the conventional M1/M2 dichotomy fails to fully capture the dynamic, phenotypically heterogeneous, and metabolically constrained macrophage states that emerge during infarct healing. In this review, we synthesize current evidence supporting a trajectory-based framework for macrophage reprogramming following MI and emphasize mitochondrial fitness as a critical determinant governing the transition from sustained inflammation to reparative resolution. We summarize key metabolic checkpoints regulating this functional shift-including glycolytic rewiring, tricarboxylic acid (TCA) cycle remodeling, mitochondrial reactive oxygen species (mtROS) accumulation, efferocytosis, oxidative phosphorylation (OXPHOS), fatty acid oxidation (FAO), and mitochondrial quality control. Furthermore, we advance the hypothesis that SIRT3-the principal mitochondrial NAD+-dependent deacetylase-may act as a central regulatory node linking mitochondrial protein acetylation to macrophage state transitions after MI. Specifically, we outline a staged dual-axis working model, generated from convergent but largely indirect evidence, in which the SOD2-mtROS axis is more closely linked to early nonresolving inflammation, whereas the PDHA1-metabolic flexibility axis may be more relevant to efferocytosis-associated reparative transition. We further highlight NAD+ availability as an upstream limiting factor that may constrain SIRT3 activity in macrophages under ischemic-inflammatory stress. Finally, we critically evaluate the current evidence hierarchy, human translatability, therapeutic strategies, and key translational challenges-emphasizing considerations of timing, cellular specificity, delivery modalities, and target engagement. Although macrophage-specific causal evidence in myocardial infarction (MI) remains sparse, this framework is intended as a mechanistically coherent and experimentally tractable working hypothesis to guide future investigations into macrophage immunometabolism and mitochondrial-targeted interventions in post-infarction cardiac repair. Accordingly, the proposed framework should be viewed as a testable working hypothesis rather than a settled causal model of macrophage fate control in MI.\n\nID: 42564235\nTitle: Vagus nerve-driven microbiota homeostasis: a promising integrative add-on therapy for neurodevelopmental disorders.\nAbstract: Over the past two decades, the conceptualization of neurodevelopmental disorders (NDDs) has undergone a profound transformation, shifting from a primarily brain-centric framework toward a systems-level perspective that integrates peripheral physiological processes. Among these, the gut microbiota has emerged as a critical determinant of neurodevelopmental trajectories. Through its involvement in immune modulation, metabolic signaling, and neural communication, the microbiota-gut-brain axis (MGBA) exerts a pervasive influence on brain maturation and function. A growing body of evidence indicates that early-life disruptions of microbiota composition-commonly referred to as dysbiosis-are associated with an increased risk of NDDs, including autism spectrum disorder (ASD), attention-deficit/hyperactivity disorder (ADHD), and epilepsy. These disruptions are frequently driven by environmental exposures such as antibiotic use, cesarean delivery, dietary patterns, and psychosocial stress. Despite the expanding recognition of these associations, current therapeutic strategies aimed at restoring microbiota balance, including probiotics and fecal microbiota transplantation, have yielded inconsistent and often transient results. In this context, Vagus Nerve Stimulation (VNS), particularly in its non-invasive forms (nVNS), has emerged as a promising approach capable of modulating environmental exposures through the host-centered regulatory mechanisms of the MGBA. By influencing autonomic tone, activating the cholinergic anti-inflammatory pathway, and modulating neurotransmitter systems, nVNS may restore microbiota homeostasis while simultaneously improving neurodevelopmental outcomes. This article provides a comprehensive and integrative review of the mechanistic, preclinical, and clinical evidence supporting the role of nVNS as a microbiota-modulating intervention. We further discuss its potential as a safe, cost-effective and promising therapeutic strategy for neurodevelopmental disorders, with a particular emphasis on pediatric populations.\n\nID: 42559088\nTitle: Correction: The dual role of metabolic reprogramming in macrophage polarization in rheumatoid arthritis and coronary heart disease and the intervention strategy of traditional Chinese medicine.\nAbstract: [This corrects the article DOI: 10.3389/fcvm.2026.1874530.].\n\nID: 42558311\nTitle: Voluntary running reduces loss of PTEN-deficient Purkinje cells, modulates their metabolic signaling, and improves motor deficits in mice.\nAbstract: Dysregulation of the PTEN-mTORC1 signaling pathway disrupts cellular metabolism and contributes to neurodevelopmental disorders, including autism spectrum disorder (ASD). In cerebellar Purkinje cells (PCs), PTEN deficiency leads to hyperactivation of mTORC1, impaired energy homeostasis, and progressive neuronal degeneration. Given that physical exercise is a potent modulator of metabolic signaling, we investigated whether voluntary running could restore metabolic balance and ameliorate cellular and behavioral deficits in a mouse model of PC-specific PTEN deficiency. Using Pten conditional knockout (cKO) mice, we evaluated the effects of voluntary running on motor coordination, metabolic signaling, neuronal morphology and preservation, and social and non-social behaviors. Behavioral analyses revealed that running significantly improved motor performance in Pten cKO mice. At the cellular level, voluntary running increased phosphorylated AMP-activated protein kinase (pAMPK) and restored mitochondrial and lysosomal content in PC dendrites from Pten cKO mice. Unexpectedly, running further enhanced mTORC1 activity in Pten cKO mice, as indicated by increased pS6R immunoreactivity, suggesting a complex interplay between anabolic and catabolic pathways. Behavioral analyses further revealed that voluntary running reduced sex-dependent differences in social and non-social behaviors observed in sedentary Pten cKO mice. Despite persistent dendritic hypertrophy and synaptic VGLUT2 alterations, running reduced PC loss and partially normalized microglial morphology and activation. Together, these findings demonstrate that voluntary running improves metabolic homeostasis and neuronal preservation in Pten cKO mice, even in the presence of sustained mTORC1 activation. Our results highlight the therapeutic potential of physical activity in modulating metabolic pathways and mitigating neurodevelopmental pathology.\n\nID: 42558291\nTitle: IL-33 promotes efferocytosis by peritoneal macrophages by a mechanism associated with rapid granulocyte IL-13 production.\nAbstract: Resolution of inflammation is an active process that requires efferocytosis, the engulfment of apoptotic cells by macrophages, mediated by receptors such as MerTK. IL-33 is an alarmin that initiates type 2 immune responses, including increased production of IL-13, which promotes MerTK expression. The ability of IL-33 to promote efferocytosis in vivo was examined. Intraperitoneal administration of IL-33 to mice increased local MerTK+ macrophage numbers within 48h. MerTK+ macrophages were not similarly induced by free mitochondria, an alternative cell damage associated signal. Efferocytotic activity was increased rapidly in response to apoptotic thymocytes in IL-33-treated mice. The established inducer of MerTK expression, IL-13, was detected in peritoneal lavage fluid shortly after IL-33 administration. Peritoneal eosinophils expressed the IL-33 receptor and demonstrated both intracellular IL-13 by flow cytometry and significantly increased Il13 transcript expression following IL-33 treatment. In contrast, neither elevated IL-13 expression nor IL-13 protein secretion was observed in peritoneal lymphocyte populations within the first 6 hours after IL-33 administration. Primary cultures of bone marrow-derived mouse mast cells and eosinophils demonstrated IL-13 protein responses to IL-33 administration within 6\u00a0h. Mast cell-deficient Cpa3-Cre; Mcl-1fl/fl mice had significantly reduced IL-13 levels in the peritoneal cavity 3 hours after IL-33 administration when compared with mast cell-containing littermates. In contrast, IL-33-treated eosinophil-deficient \u0394dblGATA mice had similar levels of IL-13 at this time point as wild type controls. These data demonstrate that IL-33 promotes MerTK expression, critical for efferocytosis by macrophages, by a process associated with an early rapid local increase in IL-13 production to which mast cells are a substantial early contributor. These findings contribute to our understanding of clinical situations where elevated soluble IL-33 receptor (sST2) and/or lower mast cell numbers are associated with worse clinical outcome.\n\nID: 42558044\nTitle: Macrophage PIM1 Drives Atherosclerosis by Enhancing Foam Cell Formation Via CD36.\nAbstract: Atherosclerosis is characterized by the buildup of fatty plaques that thicken and stiffen arterial walls. Macrophages (M\u03c6s) significantly contribute to this process through their scavenger receptor CD36. PIM1 is a serine/threonine kinase known to modulate immune responses and cell metabolism. However, its role in M\u03c6 lipid handling and atherogenesis is not well defined. This study examines the role of PIM1 in regulating CD36 expression and function in M\u03c6s during foam cell formation and atherosclerosis progression. We performed in vitro studies by treating murine peritoneal M\u03c6s from Pim1-/- and wild-type mice with oxLDL (oxidized low-density lipoprotein). We measured CD36, PIM1, and plaque-associated proteins and mRNA levels, oxLDL binding and uptake rates, and foam cell formation. For in vivo studies, we fed myeloid-specific Pim1-deficient (Apoe-/-Lyz2Cre/+Pim1fl/fl) and their littermate control (Apoe-/-Pim1fl/fl) mice a high-fat diet for 12 weeks. We then evaluated plaque formation in their aortic sinuses and arches. Deletion of Pim1 in M\u03c6s reduced CD36 protein expression by up to 96.7% compared with wild-type controls. This led to a 49.6% decrease in foam cell formation and a 25.5% reduction in cellular cholesterol after oxLDL treatment. Pharmacological inhibition of PIM kinase activity in wild-type M\u03c6s also impaired oxLDL handling, with a 64.5% reduction in binding and a 57.9% reduction in uptake. Bulk RNA-sequencing revealed that Pim1 deficiency downregulated PPAR\u03b3 (peroxisome proliferator-activated receptor gamma) signaling. Treatment with a PPAR\u03b3 agonist restored CD36 levels in the Pim1 knockdown M\u03c6s, suggesting that PIM1 regulates CD36 through PPAR\u03b3. Moreover, Pim1 myeloid-specific deficiency caused a 69.4% reduction in atherosclerotic plaque formation. PIM1 acts as a key upstream regulator of CD36 by enhancing PPAR\u03b3 activity in M\u03c6s. The PIM1-CD36 axis promotes oxLDL binding, uptake, and foam cell formation. Targeting the PIM1/PPAR\u03b3/CD36 pathway could offer new ways to modulate M\u03c6 lipid metabolism and reduce atherosclerotic plaque progression.\n\nID: 42557310\nTitle: Macrophage-to-myofibroblast transition-derived itaconate promotes bone metastasis in lung cancer through targeting of HSPA8.\nAbstract: Lung cancer bone metastasis carries a poor prognosis, yet the metabolic determinants driving tumour-stroma crosstalk remain largely elusive. Despite extensive investigations into itaconate, a prominent immunometabolite implicated in macrophage polarization, the precise mechanisms by which it modulates bone metastasis remain unresolved. Integrating metabolomics and transcriptomics profiling, the molecular landscape of lung cancer bone metastasis is delineated and the mechanistic role of itaconate is uncovered. Further ubiquitination proteomics of tumour cells and CRISPR-Cas9-mediated knockout of the gene encoding immune-responsive gene 1 (IRG1) confirmed the results in an animal model of lung cancer bone metastasis. The macrophage-to-myofibroblast transition generated cancer-associated fibroblasts that secreted elevated levels of itaconate, significantly accelerating tumour growth. A drug affinity responsive target stability screening pinpointed heat shock protein family A member 8 (HSPA8) as a direct molecular target of itaconate. Mechanistically, itaconate promoted HSPA8 ubiquitination and subsequent proteasomal degradation, thereby releasing activated transcription factor 4 (ATF4) from cytosolic sequestration. Liberated ATF4 translocated to the nucleus, where it bound the promoter region of phosphoserine aminotransferase 1 (PSAT1) to upregulate its expression. In vivo validation demonstrated that administration of adeno-associated virus-delivered PSAT1 short hairpin RNA or of a cell-penetrating itaconate antagonist significantly reduced tumour burden and prolonged survival. Our findings elucidate an unappreciated metabolic reprogramming axis in lung cancer bone metastases: macrophage-to-myofibroblast transition-derived itaconate alleviated cytoplasmic sequestration of ATF4 via HSPA8 ubiquitination, thereby activating its transcriptional target PSAT1. This mechanism converts immunometabolic byproducts into pro-tumorigenic signals that enhance bone metastasis. Notably, the HSPA8-ATF4-PSAT1 axis was identified as a key regulatory pathway governing metabolic reprogramming, thereby establishing a translational framework for targeting immunometabolic crosstalk in bone metastasis therapy.\n\nID: 42556329\nTitle: Insulin gene-modified 3D stem cells for enhanced islet regeneration and systemic reversal of type 1 diabetes.\nAbstract: Type 1 diabetes (T1D) is a chronic autoimmune disease characterized by the destruction of pancreatic \u03b2 cells, leading to lifelong insulin dependence and an increased risk of severe complications. Three-dimensional stem cells (3D SCs) culture systems have emerged as a superior alternative by more accurately mimicking the in vivo microenvironment and enhancing stemness maintenance, regenerative efficiency, and paracrine secretion. However, studies exploring the application of 3D SCs in T1D remain limited. Here, we developed a novel serum- and cytokine-free orbital-shaking system. It enables efficient and large-scale reprogramming of somatic cells into 3D embryonic-like stem cell spheroids (Sph-Es) characterized by robust pluripotency and improved safety. To enhance therapeutic utility, Sph-Es were irradiated and transduced with INS-expressing adenoviral vectors to generate Sph-R-Ins, allowing transient insulin production without permanent genomic modification. In STZ-induced T1D mice, Sph-R-Ins improved glycemic control and glucose tolerance and increased mouse insulin and C-peptide responses, indicating improved endogenous islet function. Donor-cell tracking analyses showed no pancreatic engraftment, supporting an indirect mode of action. Additional transcriptomic, immunological, and ex vivo studies indicated that the therapeutic benefit was accompanied by ECM-related signaling changes, reduced inflammatory infiltration, enhanced M2 macrophage polarization and Treg-associated immune regulation, improved metabolic signaling, and spheroid-derived paracrine support of islet function. Together, these findings establish a mechanically guided 3D stem cell-gene therapy platform with both endocrine and immunometabolic benefits in T1D.\n\nID: 42554877\nTitle: Acid-sensing ion channels as sensors of brain metabolic state.\nAbstract: Acid-sensing ion channels (ASICs) are widely recognized as proton (H+)-gated cation channels that respond to extracellular acidification associated with pathological states such as ischemia, inflammation, and epilepsy. However, an emerging body of evidence compels a broader conceptual reframing: ASICs function as dynamic sensors of metabolic state, integrating real-time signals of neural activity, including CO\u2082-derived H+, lactate, and nano-domain pH transients, to regulate neuronal excitability and intercellular communication. Here, we review the mechanisms by which activity-dependent pH shifts arise in the brain, how lactate potentiates ASIC gating through divalent-cation chelation and direct channel modulation, and how the tripartite neuron-astrocyte-vascular unit functions as a spatially organized pH-sensing system. We discuss how astrocytes simultaneously buffer extracellular pH and express ASICs, placing them at the center of a bidirectional metabolic feedback loop, and how ASICs in cerebrovascular cells may link neural metabolic load to vascular tone. Finally, we identify key open questions, including the spatial scale of physiologically relevant pH nano-domains, the role of ASIC tachyphylaxis as a \"use-history\" sensor, and whether ASIC-dependent metabolic signaling shapes circuit-level dynamics during sleep-wake transitions and high-demand cognitive states. This perspective reframes ASICs not merely as damage sensors but as constitutive physiological transducers of brain metabolic activity.\n\nID: 42554604\nTitle: Stress Hyperglycemia Drives CD4+ T Cell PANoptosis and Postoperative Organ Injury via Monocyte-Derived Succinate.\nAbstract: Perioperative stress hyperglycemia is a transient but frequent metabolic disturbance strongly linked to postoperative organ injury and mortality; however, the immunometabolic mechanisms driving this association remain largely undefined. In a two-center cohort of patients undergoing total aortic arch replacement, we identify stress hyperglycemia as an independent determinant of poor postoperative outcomes that associates strongly with CD4+ T cell loss. Hyperglycemia induces inflammatory PANoptosis in CD4+ T cells from patients in response to surgical trauma. This results from elevated glucose driving the accumulation and release of succinate from monocytes, which subsequently acts on CD4+ T cells to compromise mitochondrial integrity and activate ZBP1-mediated PANoptosis. Our findings define a monocyte-T cell metabolic signaling axis that transduces hyperglycemic stress via elevated succinate to adaptive immune cell death and reveal potential therapeutic targets to prevent postoperative immune dysfunction and organ injury, especially for patients with hyperglycemic comorbidities.\n\nID: 42553370\nTitle: Gut microbiota dysbiosis in sepsis and sepsis-associated organ injury: mechanisms, gut-organ axes, and therapeutic strategies.\nAbstract: Sepsis is a life-threatening syndrome caused by a dysregulated host response to infection and remains a major cause of morbidity, mortality, and organ dysfunction worldwide. Gut microbial dysbiosis in sepsis may result from both disease pathophysiology and ICU interventions, including broad-spectrum antibiotics, vasopressors, enteral or parenteral nutrition, mechanical ventilation, renal replacement therapy, immune status, and baseline comorbidities. Increasing evidence suggests that gut microbial dysbiosis is closely associated with sepsis progression and sepsis-associated organ injury, and may act as both a consequence of critical illness and a potential contributor to disease progression in selected experimental and clinical contexts. Host-microbe interactions, microbial metabolites, and immune-metabolic signaling help explain how gut dysbiosis contributes to sepsis pathophysiology. At the same time, probiotics, fecal microbiota transplantation, and selected microbial metabolites have shown possible benefits, mainly in experimental or selected clinical settings. This review integrates gut dysbiosis, microbial product translocation, microbial metabolites, and host-microbe interactions into a gut-organ axis framework, and evaluates how these mechanisms may contribute to sepsis progression, organ injury, and microbiota-targeted therapeutic strategies.\n\nID: 42552662\nTitle: Pasteurized Akkermansia muciniphila AKK PROBIO ameliorates inflammation and metabolic disorder in db/db mice with alterations in gut microbiota and hepatic TLR4/NF-\u03baB and SREBP2/HMGCR signaling.\nAbstract: Diabetes mellitus, especially type 2 diabetes mellitus (T2DM), represents a significant global health challenge. Growing evidence indicates that Akkermansia muciniphila, a promising next-generation beneficial microorganism, could help alleviate metabolic disorders. Nevertheless, its strain-specific effects and associated mechanisms require further investigation. Here, we investigated the potential effects of pasteurized A. muciniphila AKK PROBIO in T2DM using db/db mice. Our findings show that pasteurized AKK PROBIO supplementation was associated with lower fasting glucose levels, reduced inflammatory markers, and improved cholesterol balance in db/db mice. Pasteurized AKK PROBIO administration was accompanied by changes in gut microbiota composition, including enrichment of bacterial taxa linked to short-chain fatty acid (SCFA) production, and by increased GLP-1 levels and altered serum metabolites, including 9,9'-di-cis-\u03b6-carotene and l-arginine. These changes were paralleled by reduced hepatic expression of proteins related to the TLR4/MyD88/IKK\u03b1/NF-\u03baB and SREBP2/HMGCR signaling pathways. Taken together, our findings indicate that pasteurized AKK PROBIO ameliorates metabolic disorder and inflammation in db/db mice, accompanied by changes in gut microbial ecology, serum metabolites, and hepatic inflammatory/lipid metabolic signaling. This study supports pasteurized A. muciniphila AKK PROBIO as a postbiotic for further investigation in metabolic disorders. \u00a9 2026 Society of Chemical Industry.\n\nID: 42552636\nTitle: 4-Octyl Itaconate Promotes Diabetic Wound Healing by Enhancing Pro-Resolving Macrophages via the Efferocytosis-MCT1-Lactate-GPR132 Pathway and Macrophage-Independent Synergistic Effects.\nAbstract: \n\nID: 42543887\nTitle: Spatiotemporal Heterogeneity of Macrophages in Acute Pancreatitis: From Inflammatory Initiators to Repair Coordinators and Targeted Therapeutics.\nAbstract: The current management of acute pancreatitis (AP) primarily relies on supportive measures, such as fluid resuscitation, nutritional support, and infection control. However, these approaches do not adequately address the core drivers of the disease. This limitation arises from an incomplete understanding of the progression from local injury to systemic inflammation and repair, which is a dynamic process with underlying immunoregulatory mechanisms that remain insufficiently characterized. Macrophages are the key effector cells involved throughout the disease course and exhibit pronounced spatiotemporal heterogeneity during this progression. Therefore, they are central to decoding the evolution of the disease and facilitating precise interventions. In terms of spatial dynamics, tissue-resident macrophages (TRMs), which are derived from embryonic sources, and monocyte-derived macrophages (MDMs) recruited from the bone marrow serve functionally complementary roles. Their relative dominance shifts in conjunction with disease progression rather than remaining static. Temporally, the macrophage phenotype undergoes a programmed evolution, beginning with an early phase dominated by M1 proinflammatory responses, transitioning through an intermediate phase where injury and repair coexist, and culminating in a late phase characterized by M2-dominated reparative coordination. This evolution is accompanied by corresponding metabolic reprogramming. Recent single-cell and spatial multiomics studies have unveiled a functional continuum that goes beyond the traditional M1/M2 dichotomy, revealing a rich diversity of cellular subsets and their spatial niches. This insight shifts targeting strategies from broad anti-inflammatory interventions toward more precise modulation aimed at specific phases, subsets, and regions. This review systematically examines the design principles, strengths, and limitations of three classes of intervention-molecular targeting, bioactive natural products, and nanoscale delivery-and identifies the obstacles that continue to impede their clinical translation. Building on this analysis, we propose a dual-dimensional (spatiotemporal) strategy of precise modulation, integrating single-cell and spatial omics, chronobiological principles, and the traditional Chinese medical concept of yin shi zhi yi (adapting treatment to timing), with the aim of shifting AP therapy from symptomatic support toward cause-directed repair.\n\nID: 42542545\nTitle: Age- and sex-related differences in early-life gut microbiota and intestinal physiology in broiler chickens.\nAbstract: Early-life sex identification technologies are making sex-specific management increasingly feasible in broiler production, yet limited information exists on how males and females differ in the development of their gut ecosystem. While sex-related variation in growth rate and endocrine physiology is well established, much less is known about potential differences in gut morphology, barrier function, microbiota assembly, and intestinal gene expression during the starter period, where early performance divergence between males and females begins to emerge. A clearer understanding of these early-life processes is essential to refine sex-specific nutrition and management strategies. Therefore, this study investigated sex-related differences in gut morphology, intestinal permeability, microbiota composition and predicted functionality, as well as ileal gene expression related to nutrient transport, barrier function, immune response, and metabolic signaling in broilers at 7, 14, and 21\u00a0days of age. Body weight followed a typical early-life pattern and differed between sexes only at d 21, when males were heavier. Gut morphology matured similarly in both sexes, whereas gut permeability declined with age and was lower in males at d 20, suggesting a slightly tighter intestinal barrier. Microbiota structure was predominantly shaped by age, but sex-related divergence emerged with maturation from d 14 onward, especially in the cecum: males were enriched in strict anaerobic fermenters and carbohydrate-degradation/short-chain fatty acid (SCFA)-related pathways, while females showed higher abundance of Romboutsia, Flavonifractor, and other taxa linked to proteolytic metabolism and the degradation of aromatic amino acid-derived compounds. Gene expression was mainly driven by age, yet consistent sex-specific transcriptional signatures were revealed. Males were more associated with nutrient transport (e.g.,\u00a0SLC15A1, SLC30A1, SLC5A1) and epithelial functional maturation profiles (e.g., CDX) over time, whereas females were more associated with tight-junction integrity (e.g., OCLN) and amino-acid sensing/transport markers (e.g., T1R1, SLC3A1). Cecal SCFA concentrations were measured at d 21, yet no differences were found. Overall, gut development was largely age-driven, but sex-specific differences in barrier function, microbiota composition and function, and epithelial gene expression emerged with maturation, without differences in gut morphology or luminal SCFA concentrations.\n\nID: 42541333\nTitle: NLRC5-Deficient Macrophages Promote a Tumor-Permissive Phenotype via AXL- and MERTK-Mediated Efferocytosis.\nAbstract: The innate immune protein NLRC5 plays a key role in cancer immune surveillance. Reduced NLRC5 expression is associated with a poor prognosis for many types of cancers. Previously, we showed that mice with a myeloid-specific deletion of Nlrc5 (Nlrc5m\u00f8-KO) develop gastric lymphoid lesions to Helicobacter infection resembling early-stage marginal zone lymphoma. We hypothesized that NLRC5 deficiency may promote a tumor-permissive microenvironment mediated by tumor-associated macrophages (TAMs). Consistent with this hypothesis, splenic macrophages from Helicobacter-infected Nlrc5m\u00f8-KO mice had upregulated expression of genes encoding the TAM receptor tyrosine kinases, Axl and Mertk. The levels of AXL and MERTK gene expression and MERTK phosphorylation were increased in NLRC5-/- THP-1 macrophages when compared with WT cells. In response to Helicobacter stimulation, Nlrc5-/- macrophages had significantly elevated anti-inflammatory responses (IL-10, TGF-\u03b2, Socs1, Socs3) compared with WT cells. Importantly, Nlrc5-/-macrophages showed enhanced efferocytosis and reduced antigen presentation to CD8+ T cells. Pretreatment of macrophages with AXL and MERTK inhibitors (R428, UNC2025) resulted in reduced efferocytosis and phosphorylation of downstream signaling molecules, STAT3 and ERK1/2. We propose that defective NLRC5 signaling in macrophages leads to tumor-permissive responses, thereby promoting the development of gastric lymphoid neogenesis to Helicobacter infection.\n\nID: 42539792\nTitle: Fetal sex shapes maternal immune adaptation: placental extracellular vesicles differentially reprogram the phenotype, metabolism, and function of circulating monocytes.\nAbstract: Maternal immune adaptation during pregnancy is orchestrated by dynamic signals from the uterine microenvironment, including placental extracellular vesicles (pEVs) released into maternal circulation. EVs have emerged as key mediators of this crosstalk; however, their role in sex-specific immune modulation remains incompletely defined. Here, we investigated whether pEVs derived from term placentas induce sex-dependent changes in the phenotype, metabolism, and function of human monocytes. pEVs were isolated from 13 term uncomplicated placentas (six male-derived, M-pEVs, and seven female-derived, F-pEVs) and characterized by complementary approaches, revealing similar size distributions and concentrations, with differences in physicochemical properties and molecular cargo. Circulating monocytes from 17 non-pregnant female donors were exposed to M-pEVs or F-pEVs and analyzed for phenotypic, metabolic, and functional responses. pEVs induced distinct activation profiles depending on fetal sex. F-pEVs reduced CD11b and CD11c expression while increasing CD14, CD39 and IL-10 production. On the other hand, M-pEVs increased CD14 expression and enhanced IL-1\u03b2 secretion. Both nanovesicles populations increased IL-10 and CXCL8 release and promoted a shift toward classical monocytes (CD14+CD16-) with a reduction in the intermediate subsets. Metabolic analyses revealed divergent immunometabolic programs: M-pEVs promoted lactate and reactive oxygen species production, whereas F-pEVs enhanced lactate production, fatty acid uptake, lipid droplet accumulation, and mitochondrial activity without increasing ROS. Functionally, both pEV populations increased efferocytosis, with a distinct sensitivity to metabolic inhibitors. These findings demonstrate that pEVs differentially modulate circulating monocytes according to fetal sex and support a role for fetal sex in shaping maternal immunometabolic responses.\n\nID: 42537764\nTitle: Senescence of the immune system in SLE: Pathogenic mechanisms and therapeutic implications.\nAbstract: Systemic lupus erythematosus (SLE) is a heterogeneous autoimmune disease characterized by loss of immune tolerance and multi-organ inflammation. Although its pathogenesis involves multiple factors, the peak incidence of SLE in individuals over 48 years of age points to immunosenescence as a key driver of the disease.Even in younger patients, SLE frequently often presents as premature aging of the immune system. This review synthesizes recent advances in understanding how immunosenescence drives pathogenesis through immune dysregulation across major lymphocyte and myeloid subsets. Within the chronic inflammatory microenvironment, replicative exhaustion of T cells leads to accelerated telomere attrition, persistent activation of the DNA damage response, and telomerase dysfunction. This cascade culminates in the accumulation of senescent T cells displaying a characteristic CD28-CD57+KLRG1+ phenotype, accompanied by a pro-inflammatory state defined by enhanced cytotoxicity and impaired regulatory function. These characteristics correlated directly with disease activity and cumulative organ damage. The process arises from the interplay of metabolic reprogramming and epigenetic remodeling. In parallel, age-associated B cells (ABCs) accumulate, producing high-affinity anti-dsDNA and other autoantibodies, and potentiating inflammation via enhanced antigen presentation. Meanwhile, an aged bone-marrow microenvironment together with clonal hematopoiesis skews monocyte and macrophage polarization toward a pro-inflammatory (M1) profile. These cells show reduced phagocytic capacity and heightened secretion of senescence-associated secretory phenotype (SASP)-like mediators, further driving inflammaging. This review synthesizes current insights into the relationship between SLE risk and immunosenescence. We discuss the mechanisms through which immune aging instigates autoimmunity and explore emerging therapeutic strategies aimed at mitigating immunosenescence.\n\nID: 42535940\nTitle: Metabolic Reprogramming by Engineered Probiotics Potentiates Tumor Chemodynamic Immunotherapy.\nAbstract: Engineered bacteria hold promise for remodeling immunosuppressive tumor microenvironments through innate immunogenicity and localized therapeutic delivery. While bacterial-derived metabolites are increasingly recognized as key mediators, their specific roles in interkingdom crosstalk remain underexplored. Here, we develop a programmable probiotic platform leveraging Lactobacillus gasseri (LG)-tumor metabolic interplay to potentiate bladder cancer therapy. The selected LG strain demonstrates superior tumor-colonizing ability and intrinsic H2O2/lactate biosynthesis, creating an optimal tumor microenvironment for hemoglobin-modified MnOx nanoparticles to enhance chemodynamic therapy efficacy. Mechanistically, microbial metabolites, including L-leucine, orchestrate neutrophil phenotypic reprogramming by suppressing pro-angiogenic dcTRAIL-R1+ neutrophils while activating antigen-presenting CD74+ neutrophil populations. The engineered system elicites coordinated immunomodulation through multiple mechanisms: (1) promoting dendritic cell maturation, (2) increasing CD74+ neutrophil populations, (3) inducing macrophage polarization from M2 to M1 phenotypes, and (4) enhancing tumor infiltration of CD8+ T cells and natural killer cells. This study reveals that bacteria-tumor metabolic crosstalk upregulates beneficial metabolites, notably leucine, which promotes phenotypic reprogramming of neutrophils toward the antigen\u2011presenting CD74+ subset, thereby bridging innate metabolic regulation with adaptive antitumor immunity. This finding goes beyond the material-centric logic of previous probiotic-nanomaterial systems and establishes a metabolism-centric framework for bacteria\u2011mediated cancer immunotherapy.\n\nID: 42529164\nTitle: Gut microbiota and intestinal permeability in rheumatoid arthritis: pathogenic mechanisms.\nAbstract: Rheumatoid arthritis is a chronic systemic autoimmune disease in which the earliest breaks in immune tolerance may arise at mucosal surfaces before the clinical onset of synovitis. Among these sites, the gut has emerged as a particularly compelling candidate because it integrates microbial, epithelial, metabolic, and immune pathways with the potential to shape systemic inflammation. In this review, we examine the biological foundations of the gut-joint axis in rheumatoid arthritis, focusing on intestinal barrier structure, microbiome alterations, mucosal immune crosstalk, and mechanisms of barrier dysfunction. Current human evidence links rheumatoid arthritis to heterogeneous shifts in gut microbial composition, depletion of beneficial metabolite-producing commensals, altered immune-metabolic signaling, and biomarker patterns consistent with epithelial injury and microbial-product translocation. At the same time, available data do not support the existence of a single, universal microbial or permeability signature that defines the disease across populations. Recent longitudinal studies further challenge the concept of stable, long-standing dysbiosis and instead suggest a late, transient phase of ecological instability arising close to symptom onset. Experimental models provide stronger mechanistic support, showing that dysbiotic microbial communities, impaired barrier integrity, and strain-specific host-microbe interactions can promote T helper 17-skewed immunity and aggravate arthritis. Collectively, these findings support a context-dependent contribution of the gut to rheumatoid arthritis pathogenesis while underscoring the need for longitudinal, strain-resolved, and multi-omic human studies to clarify causality, refine disease models, and identify clinically meaningful windows for intervention.\n\nID: 42525822\nTitle: Ciliary ARL13B Is Essential for Body Weight Regulation in Mice.\nAbstract: The molecular mechanisms by which primary cilia regulate energy homeostasis remain poorly understood. Here, we evaluated whether the ciliary GTPase ARL13B regulates energy homeostasis and whether its localization to cilia is required to control body weight and feeding. Using genetic tools to isolate cilia-specific functions, we found that systemic exclusion of ARL13B from cilia causes hyperphagia and obesity in mice and that ciliary ARL13B is required in the nervous system for weight control. These findings identify ciliary ARL13B as a key regulator of energy homeostasis, contributing to our understanding of how primary cilia act as metabolic signaling hubs.\n\nID: 42523631\nTitle: Anti-inflammatory CAR-microglia targeting A\u03b2 for Alzheimer's disease therapy.\nAbstract: Alzheimer's disease (AD) is characterized by the accumulation of amyloid-\u03b2 (A\u03b2) plaques and chronic neuroinflammation, which together drive progressive neuronal loss and cognitive decline. In recent years, monoclonal antibodies targeting A\u03b2 have demonstrated encouraging clinical benefits in Alzheimer's disease (AD). However, their therapeutic efficacy remains limited by insufficient and unsustained clearance of A\u03b2, as well as treatment-associated neuroinflammatory responses. These limitations highlight the need for alternative strategies that can achieve efficient A\u03b2 elimination while maintaining immune homeostasis. To overcome these challenges, we developed a novel anti-inflammatory CAR-Microglia (CAR-Mic) incorporating a construct based on the TAM receptor family (TYRO3, AXL, and MERTK), which are key regulators of efferocytosis and anti-inflammatory responses. The resulting A\u03b2-targeted CAR-Mics showed enhanced A\u03b2 engulfment and reduced proinflammatory cytokines release. Among the constructs tested, AXL-CAR demonstrated the most favorable overall performance and was therefore selected for the generation of human induced pluripotent stem cell (iPSC)-derived CAR microglia-like cells (CAR-iMGLs). In an AD mouse model, AXL-CAR-iMGLs exhibited enhanced A\u03b2 clearance without evidence of severe adverse effects. Collectively, these findings establish TAM receptor-based CAR-iMGLs as a promising cell therapy model for AD and potentially other neurodegenerative disorders characterized by chronic neuroinflammation and defective pathological protein clearance.\n\nID: 42522131\nTitle: Conjugated Porphyrin Polymer With Superior Charge Transfer for Photodynamic-Immunomodulatory Prevention of CIED Infection in Diabetes.\nAbstract: Diabetic patients face heightened risks for cardiac implantable electronic devices (CIED) infections. Herein, we developed a near-infrared (NIR)-activated porphyrin polymer (PTCPP) for photodynamic therapy of CIED infections, which achieves a 100% antibacterial rate with a 22% increase in anti-biofilm efficacy compared to porphyrin (TCPP) in vitro. In diabetic rats, a 93% bactericidal rate is further demonstrated by PTCPP, along with a 97% reduction in the levels of pro-inflammatory factors. It is found that singlet oxygen (1O2) and hydroxyl radicals (\u2022OH) are the main reactive oxygen species (ROS), which can eliminate methicillin-resistant Staphylococcus aureus by disrupting mature biofilms. The immunomodulatory effect of PTCPP stems from dynamic regulation of macrophage polarization. Under irradiation, ROS induce M1 activation to eliminate pathogens, followed by metabolic reprogramming that promotes healing-conducive M2 polarization, thereby accelerating tissue repair. This work showcases the great potential of synergistic photodynamic-immunomodulatory strategies for the next-generation prevention of complex implant-related infections.\n\nID: 42521056\nTitle: Hypothalamic-pituitary-adrenal axis response and glucose homeostasis during exercise to fatigue before and after training in old and young adult Standardbred mares.\nAbstract: While reduced cortisol responses to exercise have been described in older horses, the effects of aging and training on the hypothalamic-pituitary-adrenal axis (HPA axis) and downstream metabolic signaling are currently unknown. This study tested the hypothesis that age and exercise training alter the response of the HPA axis, insulin, and glucose during an acute exercise challenge to fatigue. Six old (22.0 \u00b1 0.7 years) and six young adult (7.3 \u00b1 0.6 years) unfit Standardbred mares were tested. Mares ran a graded exercise test before (GXT1) and after (GXT2) 8 weeks of training (\u223c60% of HRmax, 3 days/week). Data was analyzed using mixed-effects models with significance of fixed effects determined by ANOVA. There was a significant effect of training on plasma glucose, with higher concentrations during GXT1 vs. GXT2 (P = 0.01), but there was no effect of age. Young horses had lower plasma insulin concentrations than old horses during GXT2 (P = 0.005), but not during GXT1. Age or training did not significantly affect plasma cortisol concentrations, but plasma ACTH was higher during GXT2 vs. GXT1 (P = 0.03), with no effects of age. At VO2max, the relationships between ACTH and cortisol were negative during GXT1 and positive during GXT2 for both age groups; however, these findings were not statistically significant. Training, but not aging, alters horses' ACTH and glucose responses to acute exercise. Aging affects horses' insulin response during acute exercise after training, with young horses having lower insulin responses post training than old horses.\n\nID: 42564122\nTitle: Cigarette smoke modulates virulence-related properties and host immune responses in Klebsiella pneumoniae.\nAbstract: Cigarette smoke is a major risk factor for respiratory infections and chronic inflammatory lung diseases, yet the mechanisms through which it alters host-pathogen interactions remain incompletely understood. Klebsiella pneumoniae is an opportunistic Gram-negative pathogen that causes severe infections, particularly in susceptible individuals. This study investigated the effects of cigarette smoke extract (CSE) on K. pneumoniae virulence-associated traits and host immune responses. Three multidrug-resistant, extended-spectrum \u03b2-lactamase-producing clinical K. pneumoniae isolates were exposed to CSE. Bacterial growth, virulence gene expression (mrkA, luxS, and AcrB), biofilm formation, antimicrobial susceptibility, macrophage invasion, neutrophil phagocytosis, and cytokine responses in THP-1-derived macrophages were evaluated using microbiological, molecular, and cell culture assays. High concentrations of CSE (\u226525%) suppressed bacterial growth, whereas 5-10% CSE had minimal effects. Exposure to 10% CSE significantly upregulated mrkA, luxS, and AcrB expression. Biofilm formation increased by 20.8-37.0%, and minimum inhibitory concentrations of ciprofloxacin and tigecycline increased two-fold following CSE exposure. CSE enhanced bacterial invasion of THP-1 macrophages and impaired neutrophil phagocytosis, reducing bacterial uptake by 17.8% and 29.9% after 30 and 60 min, respectively. Furthermore, CSE promoted a pro-inflammatory response characterized by increased TNF-\u03b1 and IL-1\u03b2 expression and reduced IL-10 expression across multiple time points. CSE enhances the virulence potential of K. pneumoniae while disrupting innate immune defenses and immune regulation. These findings demonstrate a harmful synergy between cigarette smoke and bacterial infection that may contribute to the increased susceptibility and severity of respiratory infections observed in smokers.\n\nID: 42562416\nTitle: Disruption of the CD47-SIRP\u03b1 Axis Causes Profound Reduction of Parasitaemia in Mice Infected With Babesia microti.\nAbstract: Human babesiosis is an emerging disease in North America caused by the red blood cell (RBC)-infecting parasite Babesia microti. Despite a rise in clinical cases in recent years, the pathogenesis and host immune response to B. microti infection remain unclear. CD47 is a 'marker of self' transmembrane glycoprotein expressed on cell membranes that inhibits phagocytosis through interactions with macrophage signal-regulatory protein alpha (SIRP\u03b1). We posit that disruption of CD47-SIRP\u03b1 signalling will induce macrophage uptake of Babesia-infected RBCs and reduce parasitaemia in susceptible hosts. To evaluate this, we compared the in\u00a0vivo clearance of B. microti in CD47 knockout (CD47-/-) mice and wild-type C57BL/6J mice. Our results showed pronounced differences in infection kinetics between the two mouse strains. C57BL/6J mice showed steadily increasing parasitaemia that peaked at an average of 12%, whereas CD47-/- mice exhibited parasitaemia that never exceeded 1.5% throughout infection. Parasitaemia became undetectable by Day 21 in C57BL/6J and by Day 16 in CD47-/- mice, indicating resolution of infection. These results imply that, in the absence of CD47, growth of B. microti is diminished due to more efficient phagocytosis of infected RBCs by macrophages. We propose that CD47-SIRP\u03b1 signalling plays a key role in the innate response to Babesia and suggest CD47 modulation as a new therapeutic target for the treatment of babesiosis.\n\nID: 42561801\nTitle: Macrophage polarization-inducible cholesterol lipid-assisted nanoparticles prime systemic antitumor immunity.\nAbstract: Nanomaterials with intrinsic biological activity can directly participate in disease treatment, emerging as a pivotal focus in the development of next-generation therapeutics. In this study, we synthesized a library of cholesterol lipids bearing diverse tertiary amine head groups via a straightforward amidation reaction, then co-assembled them with amphiphilic polyethylene glycol-poly (lactic-co-glycolic acid) (PEG-b-PLGA) to formulate hybrid nanomaterials. Notably, the cholesterol derivative A3-Chol-formulated nanomaterials (A3-Chol@NP) polarized macrophages toward the pro-inflammatory M1 phenotype and enhanced phagocytosis of tumor cells. At the mechanistic level, A3-Chol@NP has been observed to preferentially interact with mitochondria in macrophages to produce mitochondrial reactive oxygen species (mtROS). This, in turn, activates ROS-NF-\u03baB-iNOS and ROS-IRF5-IL-23 pathways, which have been identified as key factors in the macrophage polarization to M1-type. In the B16-F10 mouse melanoma model, A3-Chol@NP efficiently suppressed tumor growth via macrophage-mediated immunotherapy and completely blocked tumor progression when combined with anti-PD-L1 antibody.\n\nID: 42558878\nTitle: Obesity-induced metabolic reprogramming of the tumor immune microenvironment: mechanisms, spatial niches, and immunotherapy response.\nAbstract: Obesity is a major global health challenge and an established risk factor for cancer. Beyond increasing tumor incidence, obesity reshapes the tumor immune microenvironment (TIME) through systemic metabolic reprogramming, adipokine dysregulation, chronic inflammation, and gut microbiota alterations. These systemic changes create spatially organized immunosuppressive metabolic niches, including adipocyte-rich, hypoxic/lactate-enriched, myeloid-dense, and CAF/ECM barrier regions. Such niches restrict effector T-cell and NK-cell function while supporting regulatory T cells, tumor-associated macrophages (TAMs), and myeloid-derived suppressor cells (MDSCs), collectively promoting tumor progression and therapy resistance. Obesity also generates context-dependent effects on immune checkpoint blockade (ICB), a phenomenon known as the \"obesity paradox, \" in which immune suppression coexists with increased checkpoint dependency. Understanding how obesity modulates tumor cell metabolism, immune-cell metabolic fitness, and stromal remodeling is essential for designing effective interventions. Therapeutic strategies combining metabolic modulation, ICB, lifestyle intervention, and microbiota-targeted therapies may convert obesity-driven immune suppression into actionable vulnerabilities. Integrating systemic metabolic indicators, immune-cell signatures, and spatial biomarkers will enable precision stratification of patients and inform combination immunotherapy strategies in obesity-associated cancers.\n\nID: 42555863\nTitle: Metabolic Modulation for Liver Regeneration in Hepatocellular Carcinoma: From Biological Mechanisms to Precision Regenerative Medicine.\nAbstract: Background: Liver regeneration is essential after hepatectomy, but it is frequently impaired in patients with hepatocellular carcinoma (HCC) due to cirrhosis, metabolic dysfunction, sarcopenia, malnutrition, aging, and systemic inflammation. Post-hepatectomy liver failure remains a major clinical challenge. Objective: This review summarizes metabolic mechanisms underlying liver regeneration and explores metabolic vulnerabilities in patients with HCC, along with emerging therapeutic strategies to enhance regenerative capacity. Methods: A narrative review of current literature was conducted focusing on hepatic regenerative biology, metabolic reprogramming, and clinical metabolic interventions relevant to perioperative liver care. Results: Liver regeneration is regulated not only by growth factor signaling but also by coordinated metabolic reprogramming, including energy metabolism, lipid oxidation, amino acid homeostasis, mitochondrial function, and inter-organ crosstalk. Patients with HCC often exhibit impaired regenerative metabolism. Emerging interventions include nutritional optimization, branched-chain amino acid supplementation, L-carnitine administration, exercise-based prehabilitation, and modulation of the gut-liver axis. L-carnitine is highlighted as a mitochondrial modulator with potential benefits for hepatic function and muscle preservation. Conclusion: Targeting metabolic pathways represents a promising strategy to enhance liver regeneration. Integrating metabolic biomarkers and personalized interventions may improve perioperative outcomes in HCC patients undergoing hepatectomy.\n\nID: 42555352\nTitle: Circulating cochlin LCCL domain binds to dying cells and enhances efferocytosis.\nAbstract: Clearance of dead cells by efferocytosis is a critical process for homeostasis, notably by limiting inflammation. Defective efferocytosis has been associated with autoimmune, neurodegenerative, and cardiovascular diseases, as well as chronic infections, making its regulation a potential therapeutic target. Here, we identify circulating cochlin LCCL (Limulus factor C, Cochlin, and Lgl1) domain as a regulator of efferocytosis. Using cell binding assay for recombinant cochlin LCCL domain, we establish its tropism for dead or dying cells of both immune and non-immune lineages from murine and human origins. By three independent functional assays, we demonstrate that endogenous and exogenous cochlin LCCL domain enhances macrophage efferocytosis in vitro and in vivo in lipopolysaccharide (LPS)-induced inflammation and intranasal Pseudomonas aeruginosa infection, to a similar extent as the efferocytosis promoter GAS6. Our findings provide a role of cochlin LCCL domain in the regulation of efferocytosis, alongside its already described pro-inflammatory role, as an immunomodulator for host response and homeostasis.\n\nID: 42553038\nTitle: Nutrient deprivation increases CD3 expression in RAW cells and augments the CD3-induced proinflammatory profile, associated with NFAT and IRF-1.\nAbstract: Myeloid cells can express lymphoid markers, including components of the CD3-TCR complex. CD3+ macrophages have been identified in both infectious and non-infectious pathologies; however, their origin and signaling mechanisms remain poorly studied, primarily due to their low prevalence in human samples. Utilizing the RAW murine macrophage cell line as a model, this study aimed to ascertain whether nutrient deprivation induces CD3 expression and to identify the signaling molecules involved in the activation of a CD3-dependent proinflammatory profile. Firstly, the impact of environmental stress, specifically nutrient deprivation, on CD3 expression over a period was assessed. Subsequently, RAW cells were stimulated with anti-CD3 and IgG2a, and the profile of proinflammatory cytokines was evaluated alongside the expression of signaling proteins, including NFAT, c-Jun, and IKK. Furthermore, the transcriptional regulation of IRF-1, GATA-3, and MAFB was examined. Lastly, the functional capacity of CD3+ RAW cells was determined through a phagocytosis assay. RAW cells were found to express molecules classically associated with T cells, including CD3, TCR, and CD4. Notably, CD3 expression was significantly upregulated at both the protein and transcriptional levels under nutrient deprivation, although it did not reach the levels observed in T cells. Functionally, CD3+ RAW cells exhibited enhanced phagocytic activity toward latex beads. Furthermore, stimulation with anti-CD3 plus IgG2a induced a robust proinflammatory cytokine response, characterized by the secretion of IFN-\u03b3, TNF, and IL-6 as early as 5 hours post-stimulation. This response was associated with activation of signaling pathways involving NFAT, c-Jun, and IKK, along with increased IRF-1 expression and downregulation of MAFB, supporting the establishment of a CD3-dependent proinflammatory profile in RAW cells. Our findings establish RAW macrophages as a model to study CD3+ signaling machinery in myeloid cells. We demonstrate for the first time that nutrient deprivation induces CD3 expression and that the resulting CD3-driven proinflammatory program is associated, at least in part, with NFAT and IRF-1. These conclusions provide new insights into the origin and functional significance of CD3+ macrophages and offer a valuable platform for investigating the impact of this pathway on innate immune responses across various pathological contexts.\n\nID: 42552059\nTitle: \u03b2-glucan elicits APOE-dependent peripheral trained immunity to suppress hepatocellular carcinoma.\nAbstract: Although immunotherapy has revolutionized cancer treatment, hepatocellular carcinoma (HCC) continues to demonstrate limited clinical responses, highlighting the urgent need for novel immunomodulatory strategies. Trained immunity, an emerging paradigm wherein innate immune cells develop a memory-like phenotype through epigenetic and metabolic reprogramming, offers a promising avenue to remodel the immunosuppressive tumor microenvironment. This study investigated whether \u03b2-glucan-induced trained immunity could potentiate antitumor immunity against HCC. We established orthotopic HCC mouse models to investigate the role of trained immunity induced by whole \u03b2-glucan particle (WGP) in the HCC microenvironment, particularly in modulating hepatic apolipoprotein E (APOE)-positive monocytes/macrophages. Transcriptional changes in trained monocytes/macrophages were identified by analyzing single-cell RNA sequencing and bulk RNA-sequencing data from the livers of WGP-treated and control mice. Mechanistic studies were performed using Apoe -/- mice and in situ monocyte/macrophage engineering. Flow cytometry was performed to assess immune cell phenotypes and phagocytosis, while luminescence-based assays were used to evaluate cytotoxic activity. The translational potential was assessed using human monocyte training assays. This study demonstrated that preconditioning with WGP, a trained immunity inducer, increased the accumulation of trained monocytes/macrophages in the liver and suppressed tumor progression in HCC mouse models. Mechanistically, WGP-trained APOE+ monocytes/macrophages exhibited a decrease in lipid accumulation and endoplasmic reticulum stress, thereby enhancing their antitumor function. Genetic deletion of Apoe in monocytes/macrophages abrogated the antitumor effects of WGP, demonstrating that APOE+ monocytes/macrophages are essential mediators of WGP-induced trained immunity. Adoptive transfer of WGP-trained bone marrow-derived macrophages suppressed the growth of HCC in recipient mice. Furthermore, WGP induced trained immunity in human monocytes, leading to enhanced killing of HCC cells. Notably, combination therapy with WGP and anti-programmed death-ligand 1 antibody achieved superior tumor control compared with either monotherapy. These findings identify a critical role for trained APOE+ monocytes/macrophages in WGP-mediated antitumor immunity in the liver. Harnessing WGP-induced peripheral trained immunity represents a novel therapeutic strategy for HCC.\n\nID: 42549841\nTitle: Z-Nucleic Acids: A Regulator of Macrophage PANoptosis and Fungal Biofilm in Fungal Keratitis.\nAbstract: This study aimed to investigate the role of Z\u2011nucleic acids (Z\u2011NAs) in the pathogenesis of fungal keratitis (FK), focusing on its regulatory effects on fungal immune escape, inflammation, and biofilm activity. A mouse model of FK was established by the combination of stromal scrapes and corneal contact lens with Fusarium solani. Disease severity was assessed using clinical scoring and histopathological examination. In vitro, bone marrow-derived macrophages (BMDMs) were infected with F. solani, and the efficiency of fungal phagocytosis and escape by BMDMs was determined through fungal counting. The expression of Z\u2011DNA binding protein 1 (ZBP1)-PANoptosis markers in corneal tissues and BMDMs was detected by western blot, and the localization of Z-NAs in these samples was examined by immunofluorescence staining. Additionally, Z\u2011NA expression within in vitro fungal biofilms was detected by immunofluorescence, and its roles in modulating biofilm activity, antifungal drug resistance, and chemotactic ability were further characterized. ZBP1-PANoptosis was significantly activated in FK corneal tissues and positively correlated with clinical severity in FK. F. solani infection triggered Z\u2011NA transformation and ZBP1-PANoptosis activation in BMDMs, which in turn promoted fungal immune escape and exacerbated inflammation. Z\u2011NAs accumulated as extracellular DNA in fungal biofilms and were shown to regulate biofilm activity, drug resistance, and chemotaxis. Z\u2011NAs play a dual pathogenic role in FK by inducing ZBP1-PANoptosis in macrophages and enhancing biofilm function, thereby promoting the progression of FK.\n\nID: 42548808\nTitle: Glucose metabolism in tumor-associated macrophage plasticity and cancer immunity.\nAbstract: Tumor-associated macrophages (TAMs) are key immune cells in the tumor microenvironment and play critical roles in tumor progression, immune escape, and therapeutic response. Their functional plasticity is closely regulated by metabolic reprogramming, particularly glucose metabolism. Glucose-related pathways, including glycolysis, gluconeogenesis, the pentose phosphate pathway, glycogen metabolism, and pyruvate/lactate metabolism, influence TAM polarization, cytokine production, phagocytosis, antigen presentation, and T cell interactions. In many tumors, enhanced glycolysis and lactate accumulation promote M2-like TAM polarization and suppress CD8+ T cell activity, whereas certain metabolic programs may support M1-like anti-tumor functions under specific conditions. This mini review summarizes major glucose metabolic pathways involved in TAM regulation, highlights their context-dependent pro- and anti-tumor roles, and discusses therapeutic strategies for reprogramming TAM metabolism to improve anti-tumor immunity and immunotherapy response.\n\nID: 42544579\nTitle: Small molecule inhibitor of orphan GPCR dimerization improves host defense and blood pressure control in mice.\nAbstract: Orphan GPCRs of the GPRC5 family regulate macrophage activity and vascular contractility by dimerizing with other GPCRs, but pharmacological modulation of this process has not been explored. We previously identified the dimerization interface of receptor GPRC5B and show here that both its mutation and inhibition by a decoy peptide disturbed the interaction with the prostaglandin E2 receptor EP2 in macrophages, resulting in reduced EP2 signaling, enhanced migration and phagocytosis, and protection from bacterial peritonitis in mice. Furthermore, we show that a similar interface exists in related receptor GPRC5C, and, the same as in GPRC5B, mutation or inhibition by decoy peptide improved host defense. Through a virtual docking screen, we identified a small molecule inhibitor of both GPRC5B and GPRC5C dimerization, K303MP20, and showed that it reduced EP2 signaling, enhanced macrophage activity, and improved host defense in bacterial peritonitis and influenza A infection. Interestingly, K303MP20 not only blocked dimerization between GPRC5B/C and EP2, but also with prostacyclin receptor IP and angiotensin II receptor AT1, resulting in reduced AT1-dependent contraction and enhanced IP-dependent relaxation in human and murine smooth muscle cells. In vivo, K303MP20 did not affect basal blood pressure, but protected mice from angiotensin II-induced hypertension. Taken together, inhibition of orphan GPCR dimerization by small molecules is feasible and improves infection control and arterial hypertension.\n\nID: 42543371\nTitle: [Study on Huanglian Jiedu Decoction improving ox-LDL-induced LC3-related phagocytosis dysfunction in RAW264.7 macrophages by activating ERK5].\nAbstract: To investigate whether the anti-atherosclerotic(AS) effect of Huanglian Jiedu Decoction(HLJDD) is associated with activation of extracellular signal-regulated kinase 5(ERK5) and the consequent improvement of microtubule-associated protein 1 light chain 3(LC3)-associated phagocytosis(LAP) dysfunction in macrophages. RAW264.7 cells were randomly divided into the normal control group, oxidized low-density lipoprotein(ox-LDL) group, HLJDD group, simvastatin(simva) group, and RAW264.7-ERK5 gene knockout(ERK5-KO) group. According to the experimental protocol, cells in each group were treated for 24 h with normal control rat serum, ox-LDL, HLJDD-containing serum, or simva-containing serum. Apoptotic Jurkat cells were added to each group and co-cultured for 90 min. After removal of the supernatant, LC3-\u2161 labeling was performed to observe LAPosomes in macrophages, and the clearance of apoptotic Jurkat cells was assessed. The expression levels of phosphorylated(p)-ERK5, ERK5, LAP-related signaling molecules [T-cell immunoglobulin and mucin-domain-containing molecule-4(TIM-4), vacuolar protein sorting 34(VPS34), Beclin-1, RUN domain Beclin-1-interacting and cysteine-rich domain-containing protein(Rubicon), autophagy-related protein 5(ATG5), and autophagy-related protein 7(ATG7)], pro-inflammatory cytokines [interleukin-1\u03b2(IL-1\u03b2), interleukin-6(IL-6)], and anti-inflammatory cytokines [interleukin-10(IL-10), transforming growth factor-\u03b2(TGF-\u03b2)] were measured. RESULTS:: showed that, compared with the control group, the ox-LDL group exhibited decreased LAPosome percentage and reduced clearance of apoptotic cells, downregulated expression of p-ERK5, TIM-4, VPS34, Beclin-1, Rubicon, ATG5, and ATG7, increased IL-1\u03b2 and IL-6 levels, and no significant changes in IL-10 or TGF-\u03b2 expression. Compared with the ox-LDL group, the HLJDD and simva groups showed increased LAPosome percentage and enhanced apoptotic cell clearance, upregulated expression of p-ERK5, TIM-4, VPS34, Beclin-1, Rubicon, ATG5, and ATG7, decreased IL-1\u03b2 and IL-6 levels, and increased IL-10 and TGF-\u03b2 expression. Compared with the HLJDD group, the ERK5-KO group exhibited significantly reduced expression of ERK5 and p-ERK5, and all other indicators were reversed. In conclusion, HLJDD may ameliorate macrophage LAP dysfunction and exert anti-AS effects by activating ERK5.\n\nID: 42540405\nTitle: Translational boundaries of Txnip-targeted metabolic modulation in bone homeostasis.\nAbstract: \n\nID: 42536443\nTitle: Liver sinusoidal endothelium mediates systemic clearance of ultrasmall gold nanoparticles through secretion of circulating exosomes.\nAbstract: Liver sinusoidal endothelium featuring a unique discontinuous lining and robust endocytic activity is vital for nanoparticle retention, clearance, and translocation. However, liver sinusoidal endothelium-mediated nanoparticle elimination remains far less understood than liver macrophage uptake despite both processes being involved in hepatic detoxification. Using water-soluble Au25(o-MBA)18 (o-MBA: o-mercaptobenzoic acids) with optimized local hydrophobicity for weak protein-binding affinity and high endothelium targeting as probes, we report an exosome-mediated systemic clearance for endocytosed nanoclusters in sinusoidal endothelial cells. Au25(o-MBA)18 can effectively avoid phagocytosis by liver macrophage, are initially endocytosed by sinusoidal endothelial cells through clathrin-dependent endocytosis, processed through endosomal pathways, and released as exosomes containing nanoclusters into the bloodstream. During the exosome biogenesis, Au25(o-MBA)18 progressively transform into flower-like aggregates (approximately 100 nm). These circulating exosomes traverse the glomerular membrane through autophagy in glomerular endothelial cells and podocytes before urinary excretion. Here, this exosome-mediated pathway converts exogenous ultrasmall gold nanoparticles into biocompatible endogenous exosome-enveloped cargos for systemic circulation with reduced toxicity, providing a foundation for developing next generation of safe and effective nanomedicines.\n\nID: 42531783\nTitle: Dual restoration of TGF\u03b21 and MerTK in macrophages alleviates atherosclerosis via enhanced efferocytosis and anti-inflammatory polarization.\nAbstract: Although metabolic dysfunction-associated steatotic liver disease and atherosclerosis frequently coexist, no therapy concurrently targets both conditions. We previously observed that in such comorbidity settings, macrophages exhibit impaired efferocytosis and reduced anti-inflammatory polarization. In this study, we investigated whether simultaneously restoring these two defective macrophage functions could provide a unified therapeutic strategy both for hepatic and vascular pathology. To establish a comorbidity model featuring concurrent hepatic steatosis and atherosclerosis, we fed ApoE-/-mice a high-fat diet for 14\u00a0weeks. Moreover, we engineered bone marrow-derived macrophages to co-overexpress TGF\u03b21 and MerTK (M\u03c6Smart), thereby restoring anti-inflammatory properties and phagocytic capacity, then treated mice with control macrophages or M\u03c6Smart. TGF\u03b21 and MerTK overexpression in macrophages reprogrammed these cells toward an anti-inflammatory phenotype and endowed them with strong phagocytic capacity under lipid-loaded conditions. M\u03c6Smart reprogrammed macrophage injection into ApoE-/- mice alleviated inflammation locally in the plaque and liver. Consistent with the reduced inflammation, plaques became smaller and more stable after the adoptive transfer of reprogrammed macrophages. Mechanistically, the reprogrammed macrophages alleviated disease manifestations not only via direct inhibition of plaque inflammation but also by reshaping the inflammatory condition in the liver and plaque, where the transferred M\u03c6Smart predominantly accumulated. Macrophage-targeted dual-gene therapy overcomes the limitations of single-target approaches and achieves simultaneous therapeutic efficacy both in the liver and vasculature, establishing a preclinical proof-of-concept for multi-gene synergistic cell therapy in cardiometabolic disease.\n\nID: 42528542\nTitle: Emodin treatment is associated with enhanced resistance to Aeromonas hydrophila and correlates with gut microbiota-immune-metabolic modulation in Yellow River Carp: a multi-omics study.\nAbstract: Aeromonas hydrophila is a major pathogen of bacterial enteritis in aquaculture and a pathogen threatening the safety of fish products; sustainable alternatives to antibiotics are urgently needed. This study explored the potential effects of emodin in Yellow River carp (Cyprinus carpio haematopterus). Yellow River carp were used as a model, and multi-omics approaches (including 16S rRNA/ITS sequencing and untargeted metabolomics) were employed, along with evaluations of survival rate, hepatic and intestinal histopathology, quorum sensing-related virulence gene expression, and serum IgM and lysozyme activities. Emodin treatment improved survival rate, alleviated pathological damage in the liver and intestine, downregulated quorum sensing-related virulence genes (AhyR, LapA, AerA), and enhanced serum IgM and lysozyme activities. 16S rRNA/ITS sequencing revealed that emodin increased the relative abundance of Ascomycota, Firmicutes, Debaryomyces and Lactococcus, while decreasing genera such as Bosea and Legionella. Untargeted metabolomics indicated marked changes in metabolic profiles. Correlation analysis revealed that the emodin-enriched microbiota was significantly associated with metabolites and the cytokines il-1\u03b2 and tnf-\u03b1. Emodin treatment was associated with enhanced anti-infection ability in Yellow River carp, concomitant with significant alterations in the intestinal microbiota, metabolism, and immune responses, underscoring its great potential as an environmentally friendly immunostimulant in aquaculture.\n\nID: 42526292\nTitle: Spatial metabolic heterogeneity shapes CD8+ T cell function in cancer.\nAbstract: Tumors are spatially heterogeneous ecosystems in which malignant, stromal, vascular, and immune cells interact within metabolically distinct niches. These localized microenvironments are shaped by factors such as nutrient availability, hypoxia, acidosis, and immunomodulatory metabolites, all of which strongly influence CD8\u207a T cell infiltration, migration, persistence, and effector function. Growing evidence indicates that spatial metabolic heterogeneity contributes to immune exclusion, T cell dysfunction, and resistance to immunotherapy. This has been accompanied by major advances in spatial metabolomics, particularly mass spectrometry imaging, which now enable the in situ mapping of metabolites within intact tissues. Combined with transcriptomic, proteomic, and imaging-based approaches, these technologies provide unprecedented insight into how metabolism is organized across tumors and how it shapes tumor-immune interactions. In this review, we discuss how metabolic zonation shapes CD8\u207a T cell function across primary tumors and metastatic lesions. We highlight emerging evidence linking localized metabolic programs to T cell exhaustion, impaired motility, and altered immune composition, and discuss therapeutic strategies aimed at improving T cell metabolic fitness, including metabolic modulation and engineering approaches relevant to immune checkpoint blockade and adoptive cell therapies. Finally, we consider the translational potential of spatial metabolomics for biomarker discovery and the development of precision immunometabolic oncology.\n\nID: 42523252\nTitle: Molecular architecture of excitatory and inhibitory neurons in the first gustatory relay.\nAbstract: Taste perception is a major determinant of food intake and is dynamically modulated by hunger and satiety signals across species. While the peripheral and cortical representations of taste sensory stimuli are well characterized, far less is known about how metabolic state shapes taste processing in subcortical structures such as the brainstem. The rostral nucleus of the solitary tract (rNTS) is the first central relay for gustatory input, yet how fasting remodels transcriptional programs in rNTS neurons remains poorly defined. To address this gap, we performed cell-type-specific bulk nuclear RNA sequencing of molecularly defined excitatory (Vglut2+ ) and inhibitory (Vgat+ ) rNTS neurons. We combined Cre-dependent Sun1-sfGFP nuclear tagging with fluorescence-activated nuclear sorting to profile each population in ad libitum-fed and 24-hour-fasted mice. The two populations were transcriptionally distinct and differed in their baseline complement of hunger- and metabolic-sensing genes. Fasting elicited a transcriptional response that was largely restricted to excitatory, Vglut2+ , rNTS neurons, while the inhibitory population was minimally affected. In excitatory neurons, fasting reduced the expression of Gabrd, the \u03b4 subunit of the GABAA receptor that mediates extrasynaptic tonic inhibition, while leaving synaptic GABAA subunits and the glutamatergic or GABAergic neurotransmission machinery unchanged. RNAscope in situ hybridization confirmed Gabrd expression in Vglut2+ rNTS neurons and showed that Gabrd is also expressed in the non-Vglut2+ population; the cell-type specificity of the fasting response therefore reflects differential regulation of a shared gene rather than its restricted expression. Our results identify a cell-type-specific, state-dependent transcriptional signature in which fasting downregulates a mediator of tonic GABAergic inhibition in excitatory rNTS neurons, providing a candidate substrate for the metabolic modulation of taste processing within the brainstem.\n\nID: 42522759\nTitle: Metabolomics Effects of Folding Correction in Retinitis Pigmentosa Rhodopsin Mutant P23A.\nAbstract: Retinitis pigmentosa (RP) is a hereditary retinal degeneration disorder often caused by mutations in the rhodopsin gene, leading to photoreceptor death and vision loss. While structural misfolding of rhodopsin is a known contributor to disease pathology, the mechanisms of its cellular and in particular metabolic consequences are poorly understood. To study the direct effects of rhodopsin misfolding and structural rescue on cellular metabolism, we used the P23A mutant and its N2C/D282C stabilized counterpart as a structural tool to assess how differences in folding stability relate to measurable changes at the metabolite level. The engineered cysteine pair allows the formation of a disulfide bond restoring structural integrity and reinforcing the stable seven-transmembrane bundle. We used untargeted Gas Chromatography-Mass Spectrometry (GC-MS) metabolomics analysis conducted in inducible rhodopsin-expressing cell lines, providing a broad and general profiling of metabolic pathway alterations in response to the expression of RP mutants and their structurally rescued counterparts. Principal component analysis, hierarchical clustering, and K-means clustering revealed distinct metabolic signatures associated with each rhodopsin-expressing cell line, demonstrating a highly significant effect of genotype on global metabolite composition (F\u2009=\u200971.679; R2\u2009=\u20090.93724; p\u2009=\u20090.001). Pairwise comparisons and background-subtracted analyses identified consistent alterations in arginine and proline metabolism, glutathione metabolism, and the TCA cycle, nucleotide, amino acid metabolism, redox regulation, and mitochondrial function in cells expressing misfolded P23A. Pathway enrichment highlighted key metabolites in the respective pathways as candidate biomarkers for the rhodopsin P23A mutation. As this study employs a non-retinal cell system, the observed metabolic changes reflect conserved responses to rhodopsin misfolding and proteostatic stress in the ER rather than a direct model of rod cell degeneration. Our findings support the hypothesis that there is a biochemical link, most likely the UPR, between rhodopsin folding/misfolding status and metabolic homeostasis and suggest that targeted metabolic modulation may offer a complementary therapeutic avenue for treating RP.\n\nID: 42520682\nTitle: Myeloid Piezo1 improves inflammation resolution and phagocytosis in acute liver injury.\nAbstract: Acetaminophen (APAP)-induced acute liver injury (AILI) is characterized by extensive cell death and sterile inflammation, with substantial accumulation of myeloid cells in necrotic areas. Macrophages are critical elements in acute hepatic inflammation and resolution. Piezo1 is a mechanically activated ion channel that modulates innate immune responses and senses microenvironmental cues. The functions of myeloid Piezo1 in AILI remain elusive. This study aimed to determine whether myeloid Piezo1 regulates inflammation resolution and macrophage-mediated clearance during AILI. To generate the AILI mouse model, APAP was administered intraperitoneally to Piezo1fl/fl and Piezo1\u0394LysM mice, and samples were collected at 6, 24, and 48\u00a0h after treatment. Bone marrow-derived macrophages (BMDMs) were stimulated with APAP-treated normal mouse liver cell line (AML12) supernatant to mimic sterile inflammatory response. Liver histology, immunostaining, gene expression analysis, flow cytometry, intracellular Ca2+ measurements, and phagocytosis/efferocytosis assays were performed. Piezo1 exerted protective effects against hepatotoxin-induced liver necrosis and promoted liver recovery after APAP overdose. In vitro assays revealed that Piezo1 alleviated the inflammatory response in bone marrow-derived macrophages. Mechanistically, myeloid Piezo1 manifested a more reparative phenotype and enhanced phagocytic activity by upregulating MerTK expression. Specifically, Piezo1 acted through Ca2+ influx to regulate the expression of MerTK at the target binding stage. Inhibition of MerTK induced more pro-inflammatory mediators and reduced phagocytic ability, phenocopying the Piezo1 deficiency. Separately, Piezo1 modulated cytoskeletal rearrangement via the FAK/Rac1 axis during target internalization. Pharmacological activation of Piezo1 promoted pro-resolution marker expression and enhanced efferocytosis/phagocytic clearance in vitro. This study identified myeloid Piezo1 as an important regulator of macrophage-mediated inflammation resolution and dying-cell clearance during AILI, providing a basis for future exploration of Piezo1-related pathways in macrophage-mediated liver recovery.\n\nID: 42562058\nTitle: PoGPx-7, a glutathione peroxidase homolog from teleosts, exhibits bactericidal activity and activates host immune cells against bacterial infection.\nAbstract: In mammals, glutathione peroxidase 7 (GPx-7) is a member of the GPx family that exhibits peroxidase activity. Its immunological functions, especially in host defense against bacterial infection, remain unexplored in lower vertebrates. In this study, we identified a GPx-7 homolog from Paralichthys olivaceus (PoGPx-7) and investigated its roles during Vibrio alginolyticus infection. PoGPx-7 possesses a conserved GSH-Px domain and carries positive net charges. PoGPx-7 was constitutively expressed in various tissues, with significant upregulation upon bacterial challenge. Recombinant PoGPx-7 (rPoGPx-7) exhibited GPx activity and bound to V. alginolyticus via interaction with lipopolysaccharide and peptidoglycan. In addition, rPoGPx-7 could directly kill bacteria by disrupting membrane integrity, leading to severe structural damage and content leakage. The bactericidal activity was modulated by protein concentration, pH, temperature, and Zn2+. Furthermore, rPoGPx-7 bound to peripheral blood leukocytes (PBLs), reduced bacterial attachment and LDH release, and protected PBLs from cell death. It also significantly enhanced phagocytosis, respiratory burst, and acid phosphatase activity of PBLs. In vivo administration showed that rPoGPx-7 reduced bacterial loads in the tissues, and improved fish survival, whereas knockdown of PoGPx-7 increased susceptibility to infection. These findings provide the first evidence that teleosts GPx-7 functions as a dual-effector molecule with direct bactericidal activity and immunomodulatory capacity, providing an immunological insight of GPx family members on resistance bacterial infection.\n\nID: 42561943\nTitle: C9orf72-associated and sporadic FTD patient iPSC-microglia show differences in phagocytosis and gene expression.\nAbstract: C9orf72 hexanucleotide repeat expansion (C9-HRE) is a major genetic cause of amyotrophic lateral sclerosis and frontotemporal dementia (FTD). However, approximately half of the FTD patients are sporadic without a clear genetic background. To compare characteristics of microglia from different FTD subtypes, we generated induced pluripotent stem cell-derived microglia (iMG) from sporadic and C9-HRE-carrying behavioral variant FTD (bvFTD) patients and healthy controls. C9-HRE iMG displayed C9-HRE-associated RNA foci and dipeptide repeat proteins. All bvFTD iMG had fewer LAMP2-A-positive vesicles compared to control iMG. Additionally, C9-HRE iMG showed significantly increased LC3BII/I conversion after bafilomycin A1 treatment and altered phagocytic activity. The gene expression profile of C9-HRE iMG only modestly differed from the control iMG, but was greatly different from the sporadic bvFTD patient iMG. Our data show alterations in phagocytic and autophagosomal/lysosomal pathways and gene expression profiles between C9-HRE and sporadic bvFTD iMG for the first time.\n\nID: 42560551\nTitle: \u03b2-hydroxybutyrate regulates microglia M1/M2 polarization and phagocytosis through the JAK1/STAT1 pathway to reduce neuroinflammation and exert anti-epileptic effects.\nAbstract: Neuroinflammation and microglia M1/M2 polarization imbalance are among the core pathological mechanisms of epilepsy (EP), with the JAK1/STAT1 pathway being vital in neuroinflammation. \u03b2-hydroxybutyrate (BHB), a ketone body metabolite, has anti-inflammatory and neuroprotective potential, but whether it can ameliorate EP-related neurological damage by modulating this pathway remains unclear.\u00a0To investigate whether BHB regulates microglia polarization and phagocytosis through the JAK1/STAT1 pathway, attenuates neuroinflammation and neuronal injury, and thus exerts anti-EP effects.\u00a0A rat primary neuronal EP model and lipopolysaccharide (LPS)-induced M1-type microglia model were constructed, and microglia polarization, migration, phagocytosis, and neuronal damage were detected by scratch assay, flow cytometry, Hoechst 33,342/PI staining, Cell Counting Kit-8 assay, and ELISA kits. A rat model of Pentetrazol (PTZ)-induced EP was constructed to detect the effects of BHB on the symptoms of EP in rats by behavioral assessment, and to detect brain tissue damage by pathological staining. Western blot was conducted to detect microglia polarization markers, neuronal apoptosis, synapse-related proteins, and JAK1/STAT1 pathway-related proteins expression. Pathway specificity was verified using JAK1 overexpression plasmid (OE-JAK1) and STAT1 inhibitor (Fludarabine).\u00a0BHB concentration-dependently increased EP neuron viability and suppressed M1 polarization induced by LPS, and promoted M2 polarization. BHB also enhanced the migration and phagocytosis of microglia, and reduced pro-inflammatory factor release, which in turn attenuated their pro-inflammatory damage to neurons and protected synaptic integrity, and this effect was linked to its suppression of JAK1/STAT1 pathway activation. Additionally, BHB extended seizure latency, decreased seizure duration, and reduced seizure severity in EP rats, and effectively attenuated brain histopathological damage and promoted neuronal regeneration and axonal repair. Furthermore, BHB was also effective in promoting microglia M2 polarization and enhancing their phagocytosis in vivo. Overexpression of JAK1 attenuated the neuroprotective effects of BHB, and Fludarabine attenuated the impacts of overexpression of JAK1.\u00a0By inhibiting the JAK1/STAT1 pathway, BHB promotes microglia M2 polarization and enhances their phagocytosis, attenuates neuroinflammation and neuronal injury, and ultimately exerts anti-EP effects.\n\nID: 42559470\nTitle: Endothelial epigenetic senescence driven microglial activation mediates cardio-retinal neuroinflammation in heart failure.\nAbstract: Heart failure (HF) is increasingly recognized as a systemic disorder that extends beyond the heart and affects neurovascular tissues, including the retina. However, the mechanisms by which circulating factors from HF trigger retinal neuroinflammation remain unclear. HF was induced in adult mice by transverse aortic constriction (TAC). Retinal structure and function were evaluated using optical coherence tomography (OCT) and electroretinography (ERG). Parabiosis and plasma transfer experiments were performed to assess the role of circulating factors. Endothelial senescence, microglial activation, and inflammatory signaling were analyzed using immunofluorescence, qPCR, and molecular assays. The functional relevance of TGF\u03b22 and microglia was tested using anti-TGF\u03b22 antibody administration and microglial depletion with PLX5622 treatment. TAC mice exhibited pronounced retinal thinning, diminished electroretinography (ERG) amplitudes, and reduced vascular density. Exposure of healthy mice to HF plasma reproduced these abnormalities, indicating that circulating mediators drive retinal injuries. TGF\u03b22 levels were markedly elevated in the plasma of both patients with HF and TAC mice. Mechanistically, TGF\u03b22 activated the pSMAD2/EP300 pathway in retinal endothelial cells, promoting H3K9 acetylation, P21 induction, and endothelial cell senescence. Senescent endothelial cells release proinflammatory factors that activate retinal microglia, leading to hypertrophic morphology, enhanced synaptic phagocytosis, and upregulation of cytokines such as IL1\u03b2, TNF\u03b1, and IL6. Neutralization of TGF\u03b22 or microglial depletion markedly reduced inflammation, preserved the retinal architecture, and restored visual function. Elevated TGF\u03b22 levels in heart failure drive retinal endothelial epigenetic senescence, which secondarily activates microglia and induces neuroinflammation. Endothelial-specific disruption of TGF\u03b22 signaling is sufficient to protect the retina independently of primary cardiac recovery. Targeting the TGF\u03b22-endothelial-microglia axis may represent a promising therapeutic strategy for preventing retinal neurovascular degeneration associated with systemic cardiac disease.\n\nID: 42558706\nTitle: Maternal Stress Primes Adolescent Stress Susceptibility via Microglial Complement-Dependent Synaptic Phagocytosis.\nAbstract: Early-life adversity, including prenatal stress exposure, has enduring effects on stress responsivity later in life. Yet the impact of maternal stress on offspring susceptibility to stress and its underlying biological mechanisms remain to be elucidated. Here, we established a \"2-hit\" stress model to investigate whether maternal chronic unpredictable stress (E9.5 to E18) increases offspring susceptibility to social isolation during adolescence (P28 to P49). Our study reveals that maternal stress increases susceptibility to adolescent social isolation in male-but not female-offspring, manifested as increased anxiety- and depressive-like behaviors. This vulnerability is mediated by the priming of hippocampal dentate gyrus microglia through the complement C3-C3aR signaling pathway, which promotes the aberrant phagocytosis of excitatory synapses and reduces glutamatergic neuronal activity. Notably, pharmacological blockade of C3aR or chemogenetic activation of glutamatergic neurons in the dentate gyrus during adolescence effectively alleviated stress susceptibility. Therefore, our findings identify a targetable immune-mediated mechanism in the hippocampus that underlies stress vulnerability in offspring exposed to gestational maternal stress, offering new avenues for preventing adolescent-onset mood disorders.\n\nID: 42558661\nTitle: Cutaneous Intravascular Large B-Cell Lymphoma Presenting as Hemophagocytic Lymphohistiocytosis.\nAbstract: Intravascular large B-cell lymphoma (IVLBCL) is an uncommon and aggressive subtype of non-Hodgkin lymphoma defined by the proliferation of large malignant B cells confined within small blood vessels. This neoplasm can present with different nonspecific symptoms, including fever, altered mental status, livedoid skin rashes, hepatosplenomegaly, and cytopenias, often complicating its diagnosis. The main categories are classical (formerly designated as Western), hemophagocytic variant (formerly designated as Asian), and primary cutaneous IVLBCL. A distinctly severe manifestation is hemophagocytic lymphohistiocytosis (HLH), a hyperinflammatory syndrome characterized by exaggerated immune activation and macrophage activation manifested by phagocytosis of hematopoietic cells including neutrophils, red blood cells, and platelets. We describe a 72-year-old female who presented with features reminiscent of an autoinflammatory syndrome including fever and hyperferritinemia followed by clinical features concerning for HLH. She developed a reticulated skin rash. Following skin biopsy, a diagnosis was rendered of IVLBCL complicated by HLH.

These microparticles induce a systemic hypercoagulable state that rapidly transitions into secondary coagulopathy and endotheliopathy. We hypothesize that removing these microparticles from circulation could mitigate the TBI-induced secondary pathologies and improve outcomes. In this study, we investigated the role of Gas-6 (growth arrest-specific 6) as a scavenging factor for microparticles. We quantified plasma Gas-6 levels in a mouse model of TBI and administered exogenous Gas-6 either before or after TBI to evaluate its effects on endotheliopathy, coagulopathy, and outcomes. Mechanistic studies assessed Gas-6-mediated clearance of circulating microparticles in TBI mice and investigated the molecular interactions by which Gas-6 binds microparticles and macrophages to facilitate microparticle scavenging. We found that plasma levels of Gas-6 were significantly reduced in mice subjected to severe TBI. Exogenous Gas-6 given either preinjury or postinjury attenuated coagulopathy, protected the integrity of the cerebral and pulmonary endothelium, improved neurological recovery, and increased overall survival of TBI mice. Gas-6 increased the clearance of anionic phospholipid-expressing microparticles from circulation by coupling microparticles with macrophages and monocytes through the \u03b3-carboxyglutamate and the LG1 (laminin G-like domain 1), respectively, to facilitate phagocytosis of microparticles in the liver. These findings demonstrate the therapeutic potential of Gas-6 for TBI and potentially for other acute pathologies, in which microparticles initiate and propagate coagulation dysfunction and endothelial injuries.\n\nID: 42557884\nTitle: The P2X7 Receptor in Cancer: From Functional Receptor to Non-Functional P2X7.\nAbstract: The ATP-gated P2X7 receptors are abundantly expressed in immune cells, neurons, glial cells, and cancer cells. The P2X7 receptor performs distinct functions, depending on the extracellular ATP concentration and the duration of exposure to ATP. With brief ATP stimulation, the P2X7 receptor acts as an ion channel, and the movement of ions is associated with the regulation of cell proliferation and differentiation. Prolonged ATP exposure induces a conformational change in P2X7, allowing large molecules to pass through the membrane via the formation of macropores, thereby contributing to cell death. A novel function of P2X7 as a scavenger receptor was recently reported in the absence of both serum and ATP. However, the discovery of non-functional P2X7 in cancer reveals that this group of isoforms of P2X7 fails to form macropores upon ATP stimulation and cannot initiate ATP-induced cell death, allowing malignant cells to evade this regulatory mechanism and continue proliferating. We discuss the multifaceted functions of the P2X7 receptor in regulating diverse cell types, including cell growth, death, and clearance, and how the non-functional form of P2X7 disrupts this balance in cancer. Furthermore, the review explores the potential targeting of this aberrant isoform of P2X7 in the development of novel cancer therapies.\n\nID: 42557441\nTitle: Damage recognition by intestinal stem cells via Draper promotes adult Drosophila midgut regeneration.\nAbstract: Tissue regeneration after injury is crucial for restoring epithelial structure and function. Upon damage, a regenerative microenvironment forms that provides signalling cues that stimulate stem cell proliferation to replace lost cells. While this process is well understood, how stem cells themselves sense damage, translate this input into their proliferation and shape\u00a0the regenerative microenvironment remains unclear. Here we show that Draper-Src-Shark signalling in Drosophila intestinal stem cells (ISCs) recognises tissue damage by sensing externalised phosphatidylserine on dying midgut epithelial cells and is required for STAT activation in ISCs to promote their proliferation. Unlike its role in phagocytosis, Draper in ISCs does not promote the clearance of these apoptotic enterocytes but rather facilitates ISC proliferation in the presence of damaged enterocytes. Moreover, Draper-Src-Shark signalling in progenitors regulates STAT transcriptional activity in the adjacent visceral muscle, indicating that progenitors can shape the regenerative microenvironment beyond tissue boundaries. As Src and STAT are also activated in the mammalian intestinal epithelium after damage and tumour formation, these findings may help develop therapies for tissue regeneration, inflammatory diseases and cancer.\n\nID: 42556549\nTitle: LitCTL1: A novel C-type lectin involved in the mucosal and cellular immunity of the common periwinkle Littorinalittorea.\nAbstract: C-type lectins (CTLs) are vital pattern-recognition receptors (PRRs) that mediate innate immune responses in mollusks, yet their characterization in Caenogastropoda, the largest gastropod group, remains limited. This study characterizes LitCTL1, a novel secreted single-domain C-type lectin from the common periwinkle, Littorina littorea. The 199-amino acid polypeptide contains a conserved carbohydrate recognition domain with canonical QPD and WND motifs and is predicted to form a homodimer. Uniquely, LitCTL1 was localized in both circulating hemocytes and mucus-secreting epithelial cells of the foot, mantle, and hypobranchial gland - the first report of such dual localization for a molluscan lectin, linking systemic and mucosal defense. Expression analysis revealed that LitCTL1 is constitutively expressed in hemocytes. Functional assays with recombinant LitCTL1 demonstrated its role as a potent opsonin with hemagglutinating activity, significantly enhancing hemocyte spreading and the phagocytosis of zymosan. Genomic analysis reveals that LitCTL1 belongs to a rapidly diversifying, genus-specific expansion distinct from conserved perlucin-like lineages. These results identify LitCTL1 as a key effector molecule in both systemic and mucosal innate immunity, likely reflecting an evolutionary adaptation to the microbial challenges of the intertidal environment.\n\nID: 42556114\nTitle: Mechanistic insights into the immunomodulatory and antibacterial activity of the Japanese Kampo Formula Hainosankyuto.\nAbstract: This study aimed to quantify the in vitro antibacterial activity of the Japanese herbal formula Hainosankyuto (HNST) against Gram-positive and Gram-negative bacteria and to elucidate its immunomodulatory effects on human monocytes. The antibacterial activity of HNST was assessed against Escherichia (E.) coli DH5\u03b1 and Streptococcus (S.) pneumoniae D39 using bacterial growth curve analysis. The immunomodulatory effects were examined in THP-1 monocytes by quantifying phagocytosis via a gentamicin protection assay, cytokine release by enzyme immunoassay and NF-\u03baB activation using the THP1-Blue\u2122 NF-\u03baB reporter cell line. Cell viability was evaluated by microscopy and lactate dehydrogenase (LDH) release assays. The potential for lipopolysaccharide (LPS) contamination was assessed using a Limulus amoebocyte lysate (LAL) assay and validated with the TLR4-deficient THP1-Dual\u2122 KO-TLR4 reporter cell line. HNST exhibited significant antibacterial activity against the Gram-positive strain S. pneumoniae, but not against E. coli. It enhanced phagocytic activity and induced NF-\u03baB activation in THP-1 monocytes in a concentration-dependent manner. Compared to an unstimulated control, HNST moderately increased intracellular killing of bacteria. These effects were independent of its LPS content. No significant cytokine release was detected at non-cytotoxic concentrations. Cytotoxicity was observed at higher concentrations. HNST demonstrated immunomodulatory and selective antibacterial activity, which supports its traditional use as an immune-enhancing agent. However, these preliminary findings require further pharmacological and in vivo validation. The data highlight the potential of HNST as a possible complementary therapeutic approach in the era of increasing antibiotic resistance. Further studies are necessary to elucidate its active components and mechanisms of action.\n\nID: 42555848\nTitle: Assessing Vancomycin-Formyl Peptide Conjugate Binding to the Surface of Resistant Staphylococcus aureus via Flow Cytometry.\nAbstract: Staphylococcus aureus strains have emerged with resistance mechanisms that reduce the efficacy of last resort antibiotics and evade the immune system. One strategy to combat antimicrobial resistance is to modulate host immunity to eliminate infections more effectively. This has led to the development of immunotherapeutics consisting of vancomycin conjugated to formyl peptides (fPeps), with vancomycin targeting the cell wall and the fPeps engaging host innate immunity. Here, we used flow cytometry to quantify the binding of vancomycin=fPep conjugates to S. aureus clinical isolates. This revealed reduced binding of vancomycin=fPeps compared to vancomycin alone and quantified the interaction between the conjugates and the bacterial cell surface, which is important to quantify to then control the chemotactic gradient established by the fPep cargo. The direct antimicrobial activity of these conjugates was also reduced when compared to vancomycin, reflecting the reduced binding of these conjugates to S. aureus. This flow cytometry method allows quantification of vancomycin=fPep binding to bacteria and will assist in future studies to understand how attached fPeps and other immune signalling cargoes can stimulate innate immune cell activation leading to bacterial phagocytosis.\n\nID: 42554945\nTitle: GPR146 Deficiency Enhances Microglial Phagocytosis and Blood-Brain Barrier-Associated Markers in an Acute Amyloid-\u03b2 Model.\nAbstract: Dysregulation of brain cholesterol homeostasis is increasingly recognized as a critical driver of Alzheimer's disease (AD) pathogenesis. G protein-coupled receptor 146 (GPR146) has emerged as a pivotal regulator of systemic cholesterol metabolism; however, its role in the central nervous system and AD remains elusive. Here, we report that GPR146 deficiency in mice modulates ERK/PKA signaling without affecting baseline physiology or general behavior. Following intracerebroventricular (i.c.v.) injection of amyloid-\u03b2 (A\u03b2)42 oligomers, GPR146 was associated with altered A\u03b242-evoked ERK/PKA/Akt signaling both in vivo and in vitro. Mechanistically, Gpr146 ablation potentiated microglial A\u03b2 phagocytosis, which correlated with the transcriptional upregulation of phagocytic receptors, including TREM2, GPR34, P2Y6, and CR3, alongside increased expression of pro-inflammatory cytokines (TNF-\u03b1, IL-1\u03b2, IL-6). Moreover, GPR146 deficiency was linked to elevated levels of blood-brain barrier (BBB)-associated markers Cldn-5 and Glut-1 protein levels, while attenuating A\u03b2\u2011induced inflammatory responses in brain endothelial cells. At the metabolic level, GPR146 knockout modulated the expression of key enzymes governing glucose (GLUT1, GLUT3, G6PD, PFK, HK) and lipid (HMGCS1, ACACA, FASN, SCD1) metabolism and markedly reduced A\u03b2\u2011elicited lipid droplet accumulation in the cortex and hippocampus. Collectively, our findings establish GPR146 as a novel neurometabolic regulator whose deficiency correlates with enhanced A\u03b2 phagocytosis, maintenance of BBB-associated proteins, and altered cerebral metabolism, thereby presenting a potential therapeutic axis for early AD intervention.\n\nID: 42554595\nTitle: Redirecting Monocyte Differentiation With Engineered Extracellular Vesicles for Glioma Immunotherapy.\nAbstract: During glioma progression, monocytes abundantly infiltrate but primarily differentiate into immunosuppressive macrophages to promote tumor growth. Redirecting monocyte differentiation offers a compelling yet underexplored therapeutic opportunity. In this work, we found M1-polarized macrophage-derived extracellular vesicles (M1-EVs) efficiently induced monocytes to differentiate into anti-tumor macrophages via tumor necrosis factor alpha (TNF-\u03b1)-mediated signaling. Despite promising, the therapeutic efficacy of M1-EVs was constrained by insufficient glioma accumulation and CD47-mediated phagocytic inhibition. To address this challenge, we further engineered M1-EVs with dual-targeting specificity by genetically incorporating a tumor-directed chimeric antigen receptor (CAR) against IL13R\u03b12 or EGFRvIII together with CD47-blocking SIRP\u03b1 variants. The resulting dual-targeting EVs (M1-CS-EVs) exhibited enhanced blood-brain barrier (BBB) penetration and glioma accumulation while locally disrupting CD47-SIRP\u03b1 interactions. In three orthotopic glioma models, M1-CS-EVs elicited a potent anti-tumor immune response and enhanced tumor phagocytosis, significantly suppressing tumor growth while prolonging animal survival. Our findings establish a platform technology for directing monocyte differentiation toward anti-tumor phenotypes, offering a broadly applicable strategy for glioma treatment.\n\nID: 42554417\nTitle: Functional and Structural Characterization of a Large Animal Model of RDH5-Associated Retinopathy.\nAbstract: Inherited retinal diseases are a group of hereditary diseases that cause variable levels of blindness and affect a multitude of adults and children. One such disease is fundus albipunctatus (FA). FA is caused by autosomal recessive retinol dehydrogenase 5 (RDH5) mutations and results in rod dysfunction leading to night blindness and, in a subset of patients, macular degeneration (MD). We previously reported a spontaneous feline model of FA due to an RDH5 missense mutation. The affected cats showed rod dysfunction and a proportion developed degeneration of the area centralis (AC), equivalent to MD in humans. We used fundus confocal scanning laser ophthalmoscopy and spectral-domain optical coherence tomography imaging, six different electroretinography protocols, immunohistochemistry, and histology/transmission electron microscopy to further characterize this large-animal cat model. In addition to rod dysfunction, cone recovery from intense stimulation was impaired. For RDH5-/- cats that developed AC degeneration, an initial elongation of rod outer segments with disorganization of the distal tips was initially detected in the AC and visual streak, suggestive of impaired shedding/phagocytosis. With progression, photoreceptors degenerated in the AC, matching the MD seen in some human patients. The RDH5-/- cat model recapitulates features of both rod and cone dysfunction seen in human patients with RDH5 mutations. The RDH5-/- cat model offers a unique opportunity to further understand the mechanisms of RDH5-associated retinopathies and to investigate potential therapeutic approaches.\n\nID: 42552556\nTitle: Galectin-3 is elevated in M\u00fcller glia in human glaucomatous eyes and ocular hypertensive rat eyes and associated with phagocytosing states.\nAbstract: Glaucoma is a leading cause of irreversible blindness worldwide, yet available treatments fail to prevent disease progression for all patients. It is characterized by a progressive dysfunction and loss of retinal ganglion cells. Neuroinflammation has been recognized as an underlying neurodegenerative mechanism of glaucoma in animal models and human post-mortem samples, and targeting neuroinflammation may provide additional means to neuroprotection. Galectin-3, a pro-inflammatory mediator encoded by the LGALS3 gene in humans, holds promise as a treatable target as its pharmacological and genetic inhibition is neuroprotective in multiple models of experimental glaucoma. However, the role of Galectin-3 in glaucoma remains unclear, particularly whether its emergence is a consequence of degeneration, or occurs at earlier time points. To address these knowledge gaps, we labeled IBA1, GFAP, and Galectin-3 in retina sections at early glaucoma stages in the rat bead glaucoma model, and in human retina from glaucoma donors. In the rat, IBA1 volume, but not GFAP, increased at an early, pre-degenerative timepoint. Accompanying this, we identified a significant increase of Galectin-3/IBA1 colocalization compared to control at the same timepoint, supporting the upregulation of Galectin-3 in early inflammation, preceding retinal ganglion cell degeneration in experimental glaucoma. However, a significant increase in Galectin-3/GFAP colocalization compared to control at the same timepoint in the rat additionally associates Galectin-3 production with astrocytes and M\u00fcller glia. This Galectin-3 to M\u00fcller glia relationship was significantly pronounced in human glaucomatous retina, predominating over microglia co-labelling. We further demonstarted that human MIO-M1 M\u00fcller glia in vitro express Galectin-3, but this is not altered in response to glaucoma relevant stimuli (TNF-\u03b1 or mild-metabolic stress from rotenone). Instead, Galectin-3 expression was altered in phagocytosing states from exposure to E. coli particles, brain synaptosomes, or apoptotic neuronal debris. These findings provide further insight into Galectin-3 and gross inflammatory responses in glaucoma pathology.\n\nID: 42551598\nTitle: Mechanistic insight into Solanum lyratum extract for ameliorating imiquimod-induced psoriasis in mice via suppression of mast cells and Th17 cell response.\nAbstract: To investigate the underlying mechanism of Solanum lyratum Thunb. (SLT) against psoriasis. A mouse model of psoriasis was established by topical application of imiquimod (IMQ) cream on the nape and dorsal skin. Mice were randomly allocated into the blank control group, model group, SLT treatment groups (low-, medium- and high-dose), and positive control group, with 6 mice in each group. The administration lasted for 7 consecutive days. The skin lesions and pruritic behaviors of mice were observed. Hematoxylin-eosin (H&E) staining was performed to assess the pathological changes of lesional skin and spleen tissues. Toluidine blue staining was used to detect the alterations of mast cells. Immunofluorescence staining was applied to evaluate the changes of T helper 17 (Th17) cells and neutrophils in lesional skin and spleen tissues. Untargeted metabolomics profiling via ultra-performance liquid chromatography coupled with quadrupole time-of-flight mass spectrometry (UPLC-Q-TOF-MS) was conducted to identify differential metabolites in mouse serum, screen potential biomarkers, and analyze the involved metabolic pathways combined with the Kyoto Encyclopedia of Genes and Genomes (KEGG) database. Enzyme-linked immunosorbent assay (ELISA) was used to determine the content changes of interleukin (IL)-17\u202fA, IL-23, tumor necrosis factor-\u03b1 (TNF-\u03b1), IL-1\u03b2, IL-4, interferon-\u03b3 (IFN-\u03b3), vascular endothelial growth factor (VEGF), histamine (HIS), and 5-hydroxytryptamine (5-HT) in lesional skin tissues. SLT alleviated IMQ-induced psoriasis-like skin lesions and spleen edema in mice. SLT ameliorated epidermal hyperplasia and mast cell infiltration in psoriatic lesional skin, and improved inflammatory cell infiltration in both lesional skin and spleen tissues of psoriatic mice. Meanwhile, SLT regulated the levels of Th17 cells and neutrophils in the above two tissues. A total of 30 differential metabolites were screened out via serum metabolomics analysis, which were mainly enriched in signaling pathways including glycerophospholipid metabolism, fatty acid biosynthesis, biosynthesis of unsaturated fatty acids, dysregulated fatty acid metabolism, and Fc\u03b3 receptor-mediated phagocytosis. In addition, SLT significantly downregulated the contents of IL-17\u202fA, IL-23, IL-1\u03b2, HIS and 5-HT in psoriatic lesional skin. SLT exerts a dual anti-psoriatic effect of anti-inflammation and anti-pruritus by inhibiting immune cells such as Th17 cells and mast cells, thereby downregulating inflammatory factors associated with the Th17/IL-23 axis and pruritogens released by activated mast cells. Furthermore, untargeted metabolomics analysis revealed that the anti-psoriatic mechanism of SLT may be closely related to lipid metabolism disorder, a hallmark pathological feature of psoriasis.\n\nID: 42550686\nTitle: Cortical astrocytic neogenin, a key protein switching HIF1/2\u03b1-VEGFa-induced angiogenesis to MEGF10-driven phagocytosis.\nAbstract: \n\nID: 42550076\nTitle: Subunits of adaptor protein complex-1 make distinct contributions to the virulence of Cryptococcus neoformans.\nAbstract: Cryptococcal meningoencephalitis is among the most prevalent invasive fungal diseases, posing a threat to immunocompromised individuals and representing a growing global health concern. The mechanisms of cryptococcal trafficking of virulence factors during disease are incompletely understood. Adaptor protein (AP) complexes play crucial roles in intracellular trafficking by orchestrating the sorting of macromolecular cargo and serving as essential components of the endocytic and secretory pathways. In a recent study, we demonstrated that Cryptococcus neoformans cells lacking the AP-1 complex subunits exhibit impaired elaboration of virulence factors and fail to survive in the harsh conditions of the macrophage phagolysosome. Although we characterized the phenotypes of AP-1 deficient cells in vitro, the contribution of this complex to pathogenesis remains unexplored. In this study, we show that mutants deficient in AP-1 complex subunits are either avirulent or exhibit attenuated virulence in a murine inhalational model. Loss of the small subunit resulted in the formation of granuloma-like lesions in mouse lungs with early containment of infection but eventual mortality, whereas mutants lacking the large subunits were rapidly cleared by mice. The delayed onset of disease in mice caused by mutants lacking the small subunit was marked by delayed weight loss and increased respiration rate, yet the mutant exhibited enhanced dissemination during late-stage infection, coinciding with waning immune responses and elevated collagen deposition. These findings demonstrate that deficiencies in the AP-1 complex impair C. neoformans virulence, reveal distinct roles for individual subunits, and identify the complex as a potential target for therapeutic intervention in cryptococcosis.\n\nID: 42550054\nTitle: The AP-1 adaptor complex is required for cell surface modifications and the survival of Cryptococcus neoformans in phagocytic cells.\nAbstract: The pathogenic yeast Cryptococcus neoformans causes life-threatening meningoencephalitis in individuals with compromised immune systems. The ability of the fungus to cause disease depends on key cell-surface features, such as a polysaccharide capsule that protects it from the mammalian immune system. However, the mechanisms by which C. neoformans traffics polysaccharide capsule, melanin, and other materials to the cell surface are poorly understood. In this study, we employed mutants lacking specific subunits of the adaptor protein complex 1 (AP-1) to investigate its role in the elaboration of virulence-related materials at the cell surface. Importantly, the mutants displayed multiple defects, including alterations in capsule size and cell morphology, and defects in melanin production and urease secretion. Together, these results support the key observation that the AP-1 complex is required for C. neoformans survival in phagocytic cells. Together, our findings provide insights into the endomembrane trafficking machinery required for fungal pathogenesis.\n\nID: 42550039\nTitle: Innate immune recognition of Debaryomyces hansenii requires Dectin-1-Card9 signaling.\nAbstract: Innate immune signaling plays a key role in host response to infection, yet the pattern recognition receptors that detect non-model gut-associated yeasts remain poorly defined. Here, we investigated macrophage sensing of Debaryomyces hansenii, a food-derived yeast that we found to be enriched within intestinal ulcers of Crohn disease (CD) patients. Using a cell surface receptor antibody screen of bone marrow-derived macrophages infected with a CD patient isolate of D. hansenii, we showed that D. hansenii-induced macrophage activation characterized by increased expression of co-stimulatory molecules, MHC-II, and pattern recognition receptors, including the C-type lectin receptor Dectin-1. Antibody blockade experiments showed both Dectin-1 and complement receptor 3 subunit CD11b were required for phagocytosis of D. hansenii, while Dectin-1 was uniquely required for production of the pro-inflammatory cytokine tumor necrosis factor (Tnf). CRISPR-Cas9-mediated deletion of Dectin-1 phenocopied antibody neutralization effects on phagocytosis. Furthermore, deletion of Dectin-1 or its downstream signaling adaptor molecule Card9 resulted in reduced Tnf secretion in response to D. hansenii. Dectin-1-mediated uptake of D. hansenii was observed in primary bone marrow-derived macrophage and dendritic cells, as well as across the spectrum of macrophage polarization states. Together, these findings define the role of Dectin-1-Card9 signaling axis in innate immune cell sensing of D. hansenii. These findings support the emerging relevance of innate immune recognition of a yeast in Crohn disease pathogenesis.\n\nID: 42549668\nTitle: Nanomaterials-Based Immunotherapy for Atherosclerosis.\nAbstract: Atherosclerosis is considered one of the main causes of cardiovascular diseases (CVDs). Both innate and adaptive immune responses are crucial in their development. In recent years, various immunotherapies have emerged, involving mechanisms such as inflammatory cell recruitment, efferocytosis, extracellular traps, and adaptive immune vaccines. However, immunotherapeutic agents often have inherent limitations, resulting in suboptimal effectiveness or severe adverse effects. Therefore, designing nanomaterials for targeted delivery of immunotherapeutic drugs is an effective strategy to improve efficacy and reduce toxicity. This review discusses the immune features and immunotherapeutic strategies involved in atherosclerosis progression. It introduces different nanomaterial delivery systems for atherosclerosis and their applications in immune-based therapies. Additionally, this article explores future directions for nanomaterials in immunotherapy, helping researchers address clinical challenges beyond current treatments.\n\nID: 42564688\nTitle: Three-dimensional photoacoustic tomography with ultrasound localization priors.\nAbstract: Three-dimensional photoacoustic tomography (3D-PAT) enables noninvasive structural and functional imaging with optical absorption contrast and ultrasonic detection depth. However, its spatial resolution is limited by acoustic diffraction, and incomplete detection geometry can substantially degrade image fidelity and quantitative accuracy. Here, we present a ULM-guided model-based reconstruction framework, termed 3D-PAULMprior that incorporates sub-diffraction vascular priors from concurrent ultrasound localization microscopy (ULM) into 3D photoacoustic reconstruction. The method uses weighted regional Laplacian regularization to integrate high-resolution vascular information into the inverse problem, thereby enhancing vascular sharpness, suppressing limited-view artifacts, and improving blood oxygen saturation estimation. We validated 3D-PAULMprior using numerical simulations, tissue-mimicking phantoms, and in vivo mouse brain imaging. Compared with conventional reconstruction, 3D-PAULMprior reduced the system blurring, increased contrast-to-noise ratio, and enhanced structural similarity. In vivo, 3D-PAULMprior enhanced the delineation of the vascular structures that were poorly resolved in conventional reconstructions and produced more spatially confined sO\u2082 maps. These results establish 3D-PAULMprior as a robust multimodal reconstruction strategy for high-resolution structural and functional photoacoustic imaging.\n\nID: 42564594\nTitle: Impact of a Structured MRI Reporting Template on the Completeness of Primary Rectal Cancer Staging Reports: A Retrospective Audit.\nAbstract: High-resolution pelvic magnetic resonance imaging (MRI) is essential for local staging of primary rectal carcinoma and for communicating surgically relevant risk factors before multidisciplinary treatment planning. Free-text MRI reports may describe the primary tumor but may inconsistently document key management-relevant findings, including mesorectal fascia and circumferential resection margin status, depth of extramural spread, extramural vascular invasion, lateral pelvic lymph nodes, and low rectal sphincter complex involvement. This retrospective audit assessed whether use of a structured MRI reporting template was associated with improved completeness of primary rectal cancer staging reports. This retrospective audit included 60 pelvic MRI reports performed for suspected or biopsy-proven primary rectal carcinoma at a tertiary care radiology department. Thirty consecutive reports prepared before template implementation were assigned to the free-text reporting group, and 30 reports prepared after template implementation were assigned to the structured reporting group. Reports were assessed using a predefined checklist of essential MRI staging elements, including tumor location, distance from the anal verge, craniocaudal tumor length, circumferential tumor position, relationship to the anorectal junction and anterior peritoneal reflection, MRI T category, depth of extramural spread, mesorectal fascia/circumferential resection margin status, extramural vascular invasion, mesorectal nodes, tumor deposits, lateral pelvic lymph nodes, sphincter complex involvement, levator ani involvement, adjacent organ invasion, and final MRI-based risk summary. The primary and only measured outcome was report completeness. The mean completeness score was higher in the structured reporting group than in the free-text group, with mean scores of 91.3% and 58.6%, respectively. Structured reports showed more complete documentation of several clinically important staging domains that were inconsistently recorded in free-text reports, including mesorectal fascia/circumferential resection margin relationship, depth of extramural spread, extramural vascular invasion, lateral pelvic nodal assessment, and low rectal sphincter complex assessment. Structured reports also more frequently included a concise MRI-based risk summary integrating tumor level, T stage, nodal status, margin risk, extramural vascular invasion, and anticipated surgical relevance. No formal statistical hypothesis testing was performed; therefore, these findings should be interpreted descriptively rather than inferentially. Implementation of a structured MRI reporting template was associated with higher report completeness in this descriptive retrospective audit of primary rectal cancer staging reports. The structured template was associated with more complete documentation of clinically relevant reporting elements, particularly margin status, extramural spread, extramural vascular invasion, lateral pelvic nodes, and low rectal sphincter complex involvement. However, report completeness was the only measured outcome, and no formal statistical testing was performed. Further studies with statistical testing, reviewer blinding, and assessment of diagnostic accuracy or clinical outcomes are needed.\n\nID: 42564436\nTitle: Array comparative genomic hybridisation in haematological malignancies: A comprehensive review.\nAbstract: Haematologic malignancies have diverse and complex genomic abnormalities, and the correct identification is essential for making the appropriate diagnosis, providing a prognosis, and planning treatment. Improved array comparative genomic hybridisation (array CGH) can provide high-resolution, genome-wide copy number variation detection, and overcomes conventional cytogenetic limitations. The aim of this study is to determine the role of array CGH in characterising genomic aberrations of haematologic malignancies, focusing on technical advantages, added diagnostic values, and implications for disease reclassification and precision medicine. A comprehensive literature search of PubMed, Embase, Web of Science, and Scopus was conducted to identify studies evaluating the diagnostic performance and clinical utility of array CGH in haematologic cancers. Array CGH detects genomic alterations at kilobase-level resolution and reveals additional abnormalities in approximately 30% of cases with normal results by conventional cytogenetics. It improves molecular subtyping, identifies novel prognostic marker and, when combined with single nucleotide polymorphism arrays, enables detection of uniparental disomy and copy-neutral loss of heterozygosity, thereby enhancing diagnostic yield. Array CGH detects up to 90% of known genomic abnormalities in haematologic malignancies, and its integration with other genomic platforms will considerably enhance diagnostic precision and clinical care for haematopoietic neoplasms. This review emphasises the important role of array CGH's greater sensitivity to clinically relevant copy number changes compared to routine cytogenetics. Clinical applications of array CGH support precision oncology, especially when combined with single nucleotide polymorphism array or next-generation sequencing technologies.\n\nID: 42564341\nTitle: Effects of light on microbial degradation of dissolved organic matter: source-dependent regulation by lignin-like molecules.\nAbstract: The increasing input of endogenous and exogenous dissolved organic matter (DOM) into lakes, driven by intensified human activities and climate warming, is profoundly affecting the functioning of lacustrine ecosystems. However, the fate of DOM under the combined influence of light and microorganisms-especially in northern steppe lakes-remains poorly understood. Here, we integrated ultrahigh-resolution mass spectrometry (FT-ICR MS) and high-throughput sequencing in a microcosm experiment using water from Hulun Lake, the largest arid steppe lake in northern China, to compare the molecular transformation of endogenous algal-derived DOM (ADOM) and exogenous livestock manure-derived DOM (MDOM). Treatments included dark controls, light-only, microbial-only, and light-microbial coupling. Using high-resolution mass spectrometry and multi-group structural equation modeling, our results demonstrate that light regulates microbial processing of DOM through source-dependent mechanisms. Photodegradation suppressed the bioavailability of ADOM by 4.9%, largely due to combined substrate competition and reactive oxygen species (ROS) stress on key bacterial degraders. In contrast, light synergistically enhanced the bioavailability of MDOM by 5.4% through substrate facilitation. Molecular-level analysis revealed that lignin-like molecules from different sources exhibit distinct responsiveness to photochemical and microbial processing, which emerged as the key mechanistic driver for the contrasting degradation patterns. Microbial co-occurrence networks further linked specific bacterial taxa to DOM component turnover and ROS sensitivity. These findings highlight the central role of light in modulating DOM balance and source-sink dynamics in arid boreal lakes, providing novel, mechanism-based insights into the biogeochemical cycling of DOM in lake ecosystems.\n\nID: 42564314\nTitle: Balloon Passage via Microwire Navigation Technology for Severe Stenosis of Middle Cerebral Artery: A Case Report.\nAbstract: This case presents that balloon passage via microwire navigation technology could be a beneficial option for patients with severe MCA stenosis, with the diameter of the proximal blood vessel in the stenotic segment is <\u20091.5\u2009mm and there is antegrade blood flow.\n\nID: 42564295\nTitle: The Allergic Heart That Falls Apart: Type 1 Kounis Syndrome Following Concomitant Diclofenac and Ondansetron Intake.\nAbstract: Kounis syndrome is an underrecognized cause of acute coronary syndrome characterized by the coexistence of allergic reactions and myocardial ischemia. We report a case of Type 1 Kounis syndrome in a 51-year-old male who presented with acute chest discomfort, diaphoresis, and dyspnea following ingestion of diclofenac and ondansetron. Initial evaluation revealed transient anterior wall ST-segment elevation (V2-V5) with normal cardiac biomarkers and no regional wall motion abnormalities. The patient was initially managed for acute coronary syndrome; however, rapid resolution of symptoms and electrocardiographic changes, along with normal echocardiography and coronary angiography findings, suggested an alternative diagnosis. Clinical features, including GI symptoms without cutaneous manifestations, further supported an atypical allergic presentation. He was treated with intramuscular epinephrine, antihistamines, and corticosteroids, with prompt clinical improvement. A diagnosis of Type 1 Kounis syndrome secondary to drug-induced coronary vasospasm was established. This case underscores the importance of early recognition of Kounis syndrome in acute coronary presentations, particularly in the absence of biomarker elevation and obstructive coronary disease.\n\nID: 42564285\nTitle: When Virchow's Triad Goes on Overdrive: Catastrophic Multi-System Thrombosis in the Setting of New-Onset Heart Failure in a Previously Healthy Man.\nAbstract: Catastrophic multi-territory thromboembolism is an uncommon but life-threatening presentation that often signals an underlying hypercoagulable state or severe cardiac dysfunction. When all three components of Virchow's triad converge simultaneously in a previously healthy individual, the clinical consequences can be devastating and the diagnostic workup both urgent and complex. We report a 58-year-old man with no prior medical history who presented with progressive dyspnea and was found to have bilateral pulmonary emboli, large mobile thrombi in both the left atrium and left ventricle, and extensive systemic arterial thrombosis culminating in left lower extremity ischemia. Imaging revealed an underlying heart failure with reduced ejection fraction with an estimated ejection fraction of 20% and concurrent atrial flutter. Comprehensive hypercoagulable workup including antiphospholipid antibody syndrome evaluation was negative. The patient required emergent left lower extremity embolectomy at the initial hospital, transfer to a tertiary center for repeat femoral-femoral bypass that subsequently thrombosed, and ultimately a left below-knee amputation. He was discharged on apixaban. Subsequent atrial fibrillation/flutter ablation achieved durable sinus rhythm. Genetic testing revealed a pathogenic TTN (titin) variant, providing a unifying etiology for his dilated cardiomyopathy. Serial echocardiography at 3 months demonstrated resolution of all intracardiac thrombi; repeat imaging at 6 months showed substantial left ventricular ejection fraction recovery to 42%. This case illustrates that new-onset heart failure with reduced ejection fraction with concurrent atrial flutter can serve as a sufficient and independent driver of catastrophic multi-territory thromboembolism without additional systemic hypercoagulable disease. It also demonstrates that with aggressive guideline-directed medical therapy, rhythm control, and sustained anticoagulation, meaningful ventricular recovery is achievable even after severe initial dysfunction. TTN-related cardiomyopathy should be considered in otherwise unexplained dilated cardiomyopathy, and genetic counseling should be offered to first-degree relatives.\n\nID: 42564248\nTitle: Complete genome sequence and mass spectrometry assist mining siderophore turnerbactin analogs in a non-model Pseudoduganella strain with biocontrol potential.\nAbstract: Plant-associated biocontrol bacteria play a pivotal role in advancing sustainable agriculture by minimizing the reliance on toxic chemical pesticides. The order Burkholderiales is an underexplored yet highly promising group of microorganisms, characterized by a broad ecological distribution and considerable potential for application in sustainable agricultural systems. In this study, we aimed to isolate and characterize a potential biocontrol strain belonging to Burkholderiales, with the goal of contributing to eco-friendly agricultural practices and mining previously unexploited secondary metabolites. A novel bacterial strain, Pseudoduganella sp. D-3-1, was isolated from Cangma Mountain and characterized to possess potent antifungal activity and a high iron-chelating capacity. Whole-genome sequencing revealed that its complete genome spans 6,875,892 bp and encodes 6035 predicted coding sequences (CDSs), including a complete violacein biosynthesis pathway. Genome mining uncovered a diverse array of secondary metabolite biosynthetic gene clusters (BGCs), notably a non-ribosomal peptide synthetase (NRPS) gene cluster, designated the pseudodubactin cluster, which encodes a catecholate-type siderophore structurally related to turnerbactin. Through high-resolution electrospray ionization mass spectrometry (HR-ESI-MS), gene knockout, heterologous expression, and bioinformatics analysis, four turnerbactin analogs (1-4) were identified for the first time from Pseudoduganella sp., including two novel compounds: pseudodubactin A (2), and pseudodubactin B (4). Additionally, HR-ESI-MS analysis detected two uncharacterized siderophores, designated as compound 5 and compound 6, that are structurally distinct from the turnerbactin analogs. These findings indicate that Pseudoduganella sp. D-3-1 is a promising source of bioactive natural products, particularly violacein and diverse siderophores, highlighting its potential as a biological control agent for sustainable and eco-friendly agriculture.\n\nID: 42564247\nTitle: PD-1 blockade combined with anlotinib and bicalutamide for metastatic primary cutaneous apocrine carcinoma: a case report and literature review.\nAbstract: Primary cutaneous apocrine carcinoma (PCAC) is a rare malignant adnexal tumor with substantial diagnostic complexity and no established systemic therapy standard for advanced disease.Evidence for endocrine therapy, targeted therapy, and immune checkpoint inhibitors is limited to small series and case reports. A patient presented with a pruritic erythematous plaque on the left chest wall that progressively enlarged over one year. Skin biopsy and subsequent pathology consultation demonstrated invasive adenocarcinoma involving the dermis and subcutaneous tissue. Immunohistochemistry supported PCAC (CK7+, GATA3+, AR strongly positive, and patchy GCDFP-15 positivity), and a left axillary lymph node confirmed metastatic carcinoma. Whole-body 18F-FDG PET/CT revealed extensive metastatic disease involving multiple lymph node stations, lung, pleura, and multiple bones, precluding upfront surgery. The patient received systemic therapy with serplulimab (300 mg intravenously every 3 weeks) plus anlotinib (10 mg orally once daily, days 1-14 of a 21-day cycle) and concomitant bicalutamide (50 mg orally once daily). After two cycles, CT imaging showed partial reduction in pulmonary nodules and mediastinal lymphadenopathy, with thinning of the chest wall lesion and resolution of a small pleural effusion. Subsequent follow-up demonstrated continued clinical improvement of the chest wall lesion and sustained radiological disease control, without new rapidly progressive visceral lesions. No clinically significant adverse events or notable laboratory toxicities were observed during treatment and follow-up. This case illustrates a feasible combination approach for widely metastatic PCAC using PD-1 blockade, anti-angiogenic therapy, and anti-androgen treatment, with clinical and radiographic improvement and favorable tolerability during follow-up. Prospective data are needed to clarify patient selection and define optimal systemic strategies for advanced PCAC.\n\nID: 42564225\nTitle: A single-cell sequencing-based prognostic model reveals HLA-DRA, NPC2, and PRPF38B as immune-regulatory tumor suppressors in non-small cell lung cancer.\nAbstract: Non-small cell lung cancer (NSCLC) is the most common lung cancer subtype and a leading cause of cancer-related mortality due to asymptomatic early stages and poor 5-year survival, and tumor-infiltrating lymphocytes (TILs) play a pivotal but poorly defined role in NSCLC progression and prognosis within the tumor microenvironment (TME). We analyzed single-cell RNA sequencing data from GEO (GSE148466), NSCLC-related data from TCGA, and gene expression data from GEO (GSE50081). A 9-gene TIL-related risk score model (HLA-DRA, NPC2, PRPF38B, PABPC1, ENO1, ANXA2, LGALS1, S100A10, SRGN) was constructed using LASSO regression, with its prognostic value assessed via Kaplan-Meier and ROC analyses and external validation. Immune infiltration and regulatory factors were analyzed using TISIDB, pathway associations via GSVA and GSEA, and functional roles of key genes (HLA-DRA, NPC2, PRPF38\u00a0B) validated using RT-qPCR, Western blotting, and co-culture assays. TILs were abundant in both smoking and non-smoking NSCLC samples. The 9-gene risk model effectively stratified patients by survival, with high-risk patients showing poorer outcomes and enriched tumor-promoting immune features and pathways. High-risk scores were associated with increased M0 macrophages, activated NK cells, and elevated immune checkpoints. Overexpression of HLA-DRA, NPC2, and PRPF38\u00a0B inhibited NSCLC cell proliferation, migration, and invasion, while enhancing apoptosis and suppressing M2 macrophage polarization. This study establishes a TIL-based prognostic risk model for NSCLC and identifies HLA-DRA, NPC2, and PRPF38\u00a0B as potential immune-regulatory therapeutic targets with tumor-suppressive functions, providing new insights for NSCLC precision immunotherapy.\n\nID: 42564221\nTitle: Episodic cluster headache with suspected giant cell arteritis, sinusitis-related headache, and dietary triggers: a case report.\nAbstract: Cluster headache is a primary trigeminal autonomic cephalalgia characterized by severe, strictly unilateral orbital/periorbital pain with ipsilateral autonomic features. It is rare for a patient with cluster headache to have coexisting multiple headache disorders and experience unusual triggers. A 53-year-old male with a 14-year history of episodic cluster headache presented with his third cluster episode. He exhibited strictly unilateral left orbital/periorbital/temporal drilling pain [Visual Analogue Scale (VAS) 9-10/10], ipsilateral conjunctival injection, lacrimation, rhinorrhea, and agitation. Notably, during the second episode (2015), left maxillary sinusitis was identified and surgically treated, leading to immediate and complete headache resolution. During the current episode, physical examination revealed left temporal artery nodularity and tenderness-raising suspicion of giant cell arteritis. However, the erythrocyte sedimentation rate and C-reactive protein levels were within the normal range. Brain MRI/MRA revealed only nonspecific white matter changes, along with suspected wall thickening of the left superficial temporal artery. The patient declined temporal artery ultrasound, high-resolution MRI, and biopsy. In accordance with clinical guidelines, the patient was administered comprehensive treatment for cluster headache. Given the suspicion of giant cell arteritis, empirical prednisone was also initiated at a dose of 1\u2005mg/kg/day. By day 3 of treatment, attack frequency had reduced from daily to 3-4 times per week, pain intensity decreased from VAS 10/10 to 3-6/10, attacks resolved within 30\u2005min either spontaneously or after zolmitriptan, and temporal artery nodules had markedly diminished. Interestingly, during follow-up, the patient reported that ingestion of soy sauce or vinegar consistently triggered an unusual throat discomfort followed by headache within 30\u2005min, whereas avoidance of these substances resulted in no attacks. The patient's strict avoidance of soy sauce and vinegar led to a marked reduction in headache frequency over a short period, ultimately resulting in a complete absence of headache episodes. He remains under follow-up. This case highlights an unusual concurrence of episodic cluster headache with suspected giant cell arteritis and possible sinusitis-related headache in a single patient. The potential role of soy sauce and vinegar as triggers for cluster headache warrants further validation with extended follow-up and a larger case series.\n\nID: 42564204\nTitle: Targeting macrophage-mediated TGF-\u03b2/BMP signaling in ankylosing spondylitis: from inflammation to pathological bone formation.\nAbstract: Ankylosing spondylitis (AS) is a chronic, immune-mediated disease characterized by inflammatory arthritis and pathological new bone formation, ultimately leading to spinal fusion and functional impairment. Despite effective suppression of inflammation by biologic agents targeting cytokines such as TNF-\u03b1 and IL-17A, radiographic progression often continues, highlighting a critical dissociation between inflammatory activity and structural damage. The literature suggests that macrophage polarization and the TGF-\u03b2/BMP signaling axis collectively constitute a critical nexus linking inflammation to aberrant osteogenesis in AS. Moreover, it details how the unique entheseal microenvironment-shaped by biomechanical stress, hypoxia, and a distinct cytokine milieu-drives macrophages toward a spectrum of pro-osteogenic phenotypes through a mechano-inflammatory feedback loop. After that, polarized macrophages, in turn, serve as pivotal cellular engineers that locally activate and sustain TGF-\u03b2/BMP signals through proteolytic cleavage and acidic remodeling of the ECM. This self-amplifying loop directly orchestrates endochondral ossification at ligamentous insertion sites, culminating in syndesmophyte formation and spinal ankylosis. Therapeutically, this mechanistic understanding highlights promising avenues for disease modification beyond conventional anti-inflammatory strategies. Targeting macrophage polarization states or disrupting the TGF-\u03b2/BMP activation cascade may offer dual benefits-suppressing both inflammation and structural progression-and pave the way for genuine disease-modifying therapies in AS.\n\nID: 42564162\nTitle: Immunomodulation in the repair of osteonecrosis of the femoral head: reprogramming strategies for macrophages and immune cells.\nAbstract: Osteonecrosis of the femoral head (ONFH) is a severe and debilitating disease that\u00a0substantially affects patients' functional capacity and daily activities. Within necrotic femoral heads, immune cells, particularly macrophages, undergo phenotypic reprogramming. This phenotypic shift in macrophages, along with their interactions with other cell types-including osteoclasts, mesenchymal stem cells, and endothelial cells-collectively mediates disease progression. However, targeted immunotherapeutic strategies remain poorly defined. In this context, the present study reviews recent literature and provides a comprehensive overview of the immunological landscape of macrophages in osteonecrosis of the femoral head (ONFH). It summarizes current knowledge on macrophage immune reprogramming, intercellular interactions with neighboring cells (such as mesenchymal stem cells, osteoclasts, and vascular endothelial cells), and the cellular composition of immune cells (including neutrophils, B cells, and T cells) in ONFH. Furthermore, it explores the potential application of biomaterials developed through various strategies for ONFH treatment. Emerging evidence indicates that the direction of macrophage polarization and their intercellular interactions with diverse cell types (e.g., mesenchymal stem cells, osteoclasts, and vascular endothelial cells), together with the infiltration of immune cells (such as neutrophils, B cells, and T cells), collectively influence the progression of ONFH. On this basis, therapeutic strategies targeting macrophage polarization and immune cell activation are proposed, with a particular focus on biomaterials possessing diverse physicochemical properties, thereby offering insights to facilitate the clinical translation of ONFH treatments.\n\nID: 42564158\nTitle: Natural polysaccharides as immunometabolic modulators in metabolic diseases: mechanisms and translational challenges.\nAbstract: Metabolic disorders, especially obesity, type 2 diabetes mellitus, and metabolic dysfunction-associated steatotic liver disease, are becoming increasingly prevalent and have imposed a growing burden on public health systems. These diseases are commonly associated with insulin resistance and abnormal lipid metabolism, and increasing evidence indicates that immune imbalance and chronic low-grade inflammation are involved in their development. Natural polysaccharides are important bioactive components derived from plants, fungi, algae, and other natural sources. Current evidence supporting their beneficial effects in metabolic diseases is predominantly preclinical, mainly from cell-based and animal studies, while clinical evidence remains limited and heterogeneous. Natural polysaccharides have attracted interest as candidate bioactive compounds because some preparations have shown immunomodulatory and metabolic regulatory activities in experimental models. Their activities are closely related to structural features, including monosaccharide composition, glycosidic linkage types, molecular weight, branching structure, and chemical modification. Current preclinical evidence suggests that natural polysaccharides may alleviate metabolic inflammation by regulating macrophage polarization, suppressing pro-inflammatory cytokine production, modulating MAPK, NF-\u03baB, AMPK, and related signaling pathways, and reshaping the gut microbiota-immune axis. These compounds may help improve several pathological features of metabolic disorders, such as insulin resistance, abnormal lipid metabolism, inflammatory injury, and tissue dysfunction. However, several challenges still limit their translation, including unclear structure-activity relationships, inconsistent preparation standards, limited bioavailability, and insufficient well-designed clinical trials. Therefore, this review provides an overview of the natural sources, structural properties, immunomodulatory actions, and therapeutic prospects of natural polysaccharides in metabolic diseases, with a focus on their involvement in immune regulation and metabolic inflammation.\n\nID: 42564152\nTitle: Multidimensional assessment of structural post-tuberculosis lung sequelae and respiratory health status in adults from northern Peru.\nAbstract: Tuberculosis survivors often develop persistent respiratory sequelae, but data integrating structural abnormalities, functional impairment, symptoms, and respiratory health status from Latin America remain limited. To assess structural post-tuberculosis lung sequelae and their association with respiratory health status in adults from northern Peru. We conducted a prospective analytical cross-sectional study of 106 adults previously treated for pulmonary tuberculosis and evaluated at least 6\u202fmonths after treatment completion. Structural sequelae were defined as fibrosis, bronchiectasis, or residual cavitary changes on non-contrast high-resolution chest CT. Dyspnea severity was assessed with the modified Medical Research Council scale and respiratory health status with the St George's Respiratory Questionnaire. Associations were examined using robust Poisson, ordinal logistic, and linear regression models. Structural sequelae were present in 40.6% of participants, while multidimensional respiratory burden reached 59.4%. Older age was associated with structural sequelae (aPR 1.020, 95% CI 1.010-1.040), whereas longer time since treatment completion was inversely associated (aPR 0.950, 95% CI 0.920-0.980). Structural sequelae were associated with greater dyspnea severity (OR 7.680, 95% CI 3.110-20.120) and higher SGRQ scores (\u03b2 11.410, 95% CI 6.200-16.610). Structural post-tuberculosis lung sequelae were common and were associated with worse respiratory health status, supporting structured respiratory follow-up after treatment.\n\nID: 42564115\nTitle: Radiomics-based high-resolution CT analysis for differentiating primary tumor sources of pulmonary metastases.\nAbstract: To evaluate machine learning models based on HRCT radiomic features for distinguishing breast and colorectal cancer pulmonary metastases, and interpret the optimal model to aid clinical decision-making. This retrospective study enrolled 85 patients with pathologically confirmed pulmonary metastases. After radiomic feature extraction, the cohort was divided into a training set (n=59) and an independent test set (n=26) at a 7:3 ratio via stratified sampling. Data were processed with Z-score normalization, variance thresholding and PCA (45 principal components). Five classifiers were constructed: LR, linear SVM, RF, XGBoost and LightGBM. Model stability and performance were assessed by 5-fold stratified cross-validation and independent test validation. The 45 principal components accounted for 99.92% of cumulative variance. LR showed optimal performance, with a test AUC of 0.9821, classification accuracy of 84.62%, and a mean cross-validation AUC of 0.9606 (95% CI: 0.8887-0.9895). The small training-test AUC difference (0.0179) indicated no severe overfitting. SVM ranked second (test AUC\u00a0=\u00a00.9405), while XGBoost and RF exhibited significant overfitting and LightGBM underfitting. The model's decision relied on key texture features; only GLSZM non-uniformity differed significantly between groups, consistent with their pathophysiological characteristics. The PCA-reduced and regularization-optimized LR model has excellent generalization, stability and clinical interpretability in differentiating pulmonary metastases from breast and colorectal cancers. This study preliminarily highlights the potential of LR in high-dimensional small-sample scenarios, and provides a foundational methodological reference for future large-scale multicenter diagnostic research.\n\nID: 42564069\nTitle: The new era of MASH pharmacotherapy: a comprehensive review of FDA-approved and emerging agents.\nAbstract: Metabolic dysfunction-associated steatohepatitis (MASH), formerly nonalcoholic steatohepatitis (NASH), is a progressive liver disease and a leading cause of cirrhosis and liver-related mortality worldwide, affecting approximately 3%-5% of the global adult population and up to 30%-40% of individuals with type 2 diabetes mellitus (T2DM) or those attending dedicated diabetes and endocrine centers. For decades, treatment was limited to lifestyle interventions. The years 2024 and 2025 marked a paradigm shift with the first-ever FDA approvals of pharmacologic agents for MASH. This comprehensive narrative review synthesizes the evidence for newly approved and emerging pharmacotherapies for MASH, addressing the mechanisms of action, pivotal clinical trial data, efficacy, safety profiles, and place in therapy for resmetirom and semaglutide. It also discusses key agents including pioglitazone, saroglitazar, and vitamin E, and evaluates the non-invasive testing (NIT) toolkit-including FIB-4, VCTE, shear wave elastography, MRE, and ELF-in the context of a structured, risk-stratified clinical algorithm. Resmetirom (Rezdiffra), a THR-\u03b2 agonist, achieved MASH resolution in 26%-30% versus 10% placebo and fibrosis improvement in 24%-26% versus 14% placebo at 52 weeks in the MAESTRO-NASH trial. Semaglutide 2.4 mg (Wegovy) demonstrated a 28.7% delta over placebo in MASH resolution in the ESSENCE trial. Pioglitazone has additional evidence for reducing the FIB-4 index in real-world studies. Saroglitazar, a PPAR-\u03b1/\u03b3 dual agonist approved in India, has shown significant reductions in ALT, liver fat, and metabolic parameters in Phase 2 studies and is advancing to Phase 2b. Shear wave elastography is a clinically important alternative to VCTE for fibrosis staging, particularly in patients with obesity, and offers value in resolving discordant FIB-4/VCTE results. The approval of resmetirom and semaglutide marks a new era in MASH management. A risk-stratified algorithmic approach using NITs guides patient selection, with liver biopsy reserved for specific clinical scenarios. The therapeutic landscape is rapidly evolving, with saroglitazar and combination approaches representing key frontiers.\n\nID: 42564045\nTitle: SR9009 regulates macrophage polarization via the NR1D1/NF-\u03baB axis to ameliorate obesity-associated ulcerative colitis.\nAbstract: The incidence of ulcerative colitis (UC) and obesity has risen in recent years, potentially linked through metabolic dysregulation and chronic inflammation. The nuclear receptor NR1D1 is pivotal in regulating circadian rhythms and plays a significant role in inflammation and metabolism. This study investigates the therapeutic effects and mechanisms of the NR1D1 agonist SR9009 on obesity-related UC. We established a mouse model of obesity-induced UC utilizing a high-fat diet alongside dextran sulfate sodium (DSS). 32 male C57BL/6 mice were divided into four groups: control (DZ), high-fat diet (GZ), obesity associated UC model group (UC), and SR9009 intervention group (JD), with eight mice each. We evaluated body weight, blood lipids, colonic tissue alterations, IL-1\u03b2, IL-18, macrophage polarization, and NR1D1 expression levels. Mice in the UC group demonstrated significantly elevated body weight, spleen index, TG, CHOL and inflammatory markers (P\u00a0<\u00a00.01). Pathological scores of colonic tissues increased markedly (P\u00a0<\u00a00.001), with a rise in M1 macrophages (CD68+) and a decline in M2 macrophages (CD206+) (P\u00a0<\u00a00.001). NR1D1 expression was notably downregulated (P<0.01). Post-SR9009 intervention, the JD group showed significantly reduced serum TG and CHOL levels (P\u00a0=\u00a00.001, 0.011), IL-1\u03b2 and IL-18 (P<0.001), improved colonic pathology (P\u00a0<\u00a00.001), a decrease in M1 macrophages, an increase in M2 macrophages, and an enhanced M1/M2 ratio (P<0.001). SR9009 mitigates intestinal inflammation in obesity associated UC by activating NR1D1, potentially modulating NF-\u03baB-related signaling, and modulating macrophage polarization (suppressing M1 and enhancing M2). These findings propose a novel strategy for targeting NR1D1 in the treatment of obesity-related ulcerative colitis.\n\nID: 42563962\nTitle: Human interferon-\u03c9: an underappreciated type I interferon.\nAbstract: Interferon-\u03c9 (IFN-\u03c9) is a member of the human type I interferon family that has historically been overshadowed by IFN-\u03b1 and IFN-\u03b2. Recent human \"natural perturbations\", most notably selective neutralization of IFN-\u03c9 by autoantibodies in life-threatening viral infections, have renewed interest in this comparatively understudied cytokine and indicate that its antiviral activity may not always be fully compensated in defined clinical settings. This renewed focus has prompted reassessment of its single-gene organization, distinct antigenicity, intermediate receptor-binding kinetics, cellular sources, and regulatory mechanisms. In parallel, thymus-centered tolerance disorders, including autoimmune regulator (AIRE) deficiency, additional inborn errors of immune tolerance, and acquired \"sick thymus\" states, establish anti-IFN-\u03c9 autoantibodies as a stable, high-penetrance immunophenotype linking tolerance failure to durable cytokine-directed autoimmunity. Beyond antiviral defense, multi-omic studies in lupus-spectrum disease suggest tissue- and compartment-specific IFN-\u03c9 signals within broader type I interferon programs, yet endogenous IFN-\u03c9 remains rarely quantified with ligand-level resolution. This Review integrates current knowledge of IFN-\u03c9 from molecular regulation to human disease. Further progress will require subtype-resolved measurement, direct comparison with other type I interferons under matched conditions, and human genetic studies testing whether rare IFNW1 variants contribute to severe viral disease.\n\nID: 42563870\nTitle: \"Fifth-day fits\" revisited: A literature review of benign idiopathic neonatal seizures and comparison with KCNQ2- and KCNQ3-associated benign familial epilepsy syndromes.\nAbstract: Benign idiopathic neonatal seizures (BINS), colloquially referred to as the \"fifth-day fits,\"\u00a0is a clinical neonatal epilepsy syndrome associated with early, spontaneous resolution of seizures and favorable developmental outcome. Although this disease entity was first described over four decades ago, the etiopathogenesis remains unknown, and it is unclear if the syndrome represents a single, cohesive disorder or a common manifestation of various unrelated neonatal neurological disturbances. As such, there are no standardized approaches to diagnostic workup and management. Benign familial neonatal seizures (BFNS) is a well-characterized genetic syndrome associated with KCNQ2 and KCNQ3 pathogenic variants, which also manifests clinically with self-resolving seizures in the neonatal period. While it remains unclear if there is any shared pathogenesis between these two disorders, the exceedingly similar phenotypic presentations and natural history raise the question of whether consensus management approaches used in genetic BFNS can also be applied to BINS. Here, we present a topical and historical review of BINS and BFNS literature and propose specific treatment recommendations based on extrapolation of limited existing clinical data.\n\nID: 42563799\nTitle: Steroids for Drug-Resistant Seizures and Prolonged Stroke-Like Episode in a Patient With Sturge-Weber Syndrome: A Case Report.\nAbstract: Sturge-Weber syndrome (SWS) brain involvement has been associated with impairments in the blood-brain barrier (BBB) and microglial activation within involved cortical regions. Acute neurological crises, including seizures, stroke-like episodes, and/or significant headaches, are common in these patients. This report describes in detail an adolescent with SWS and acute drug-resistant status epilepticus, headache, and stroke-like episode who improved clinically when treated with high-dose steroids. Review of medical records identified two other patients previously treated with steroids for acute neurological symptoms. A 13-year-old boy with SWS brain involvement presented with fever, headache, seizures, and right-sided weakness. Brain magnetic resonance imaging (MRI) revealed characteristic findings of SWS. The patient was placed on continuous electroencephalogram that showed findings consistent with electrographic status epilepticus. Seizures were refractory to multiple anti-seizure medications as well as to an intravenous midazolam drip. A repeat MRI of the brain documented a significant increase in leptomeningeal enhancement with associated gyral edema and sulcal effacement. Steroid therapy with methylprednisolone and prednisone improved his status epilepticus and stroke-like symptoms, including resolution of seizures and marked improvement in his hemiparesis. This patient suggests a potential role for inflammation-targeted therapies in individuals with SWS brain involvement who present with prolonged neurological crises. Two other patients with SWS brain involvement who were treated with high-dose steroids in the context of acute neurological episodes also support the need for future clinical and preclinical research to validate this approach.\n\nID: 42563678\nTitle: [Study on cellular repressor of E1A-stimulated genes regulating autophagy and polarization of alveolar macrophages in sepsis-induced acute respiratory distress syndrome and its clinical value].\nAbstract: To investigate the regulatory effects of cellular repressor of E1A-stimulated gene (CREG) on autophagy and polarization of alveolar macrophages in sepsis-induced acute respiratory distress syndrome (ARDS) and its clinical value. 1) Cell experiment: Mouse monocyte/macrophage cell line RAW264.7 was cultured in vitro. Cells in logarithmic growth phase were induced to differentiate into alveolar macrophages. The alveolar macrophages were divided into four groups: the blank control group was cultured with complete medium only; the lipopolysaccharide (LPS) group was stimulated with 5 mg/L LPS for 24 hours to establish the sepsis-induced ARDS model; the CREG overexpression group was transfected with 2 mg CREG overexpression plasmid pLNCX2-CREG for 6 hours, followed by 5 mg/L LPS stimulation for 24 hours; the CREG interference group was transfected with 2 \u03bcg CREG interference plasmid pSM2-siCREG for 6 hours, followed by 5 mg/L LPS stimulation for 24 hours. Western blotting was used to detect the expression of autophagy markers [autophagy initiation key protein Beclin1, microtubule-associated protein 1 light chain 3 (LC3), and autophagic substrate protein p62]. Flow cytometry was used to detect the expression of macrophage polarization markers [M1-type characteristic marker cluster of differentiation 86 (CD86) and M2-type characteristic marker CD206]. 2) Clinical trial: A prospective case-control study was conducted in patients with sepsis admitted to the respiratory intensive care unit of The First Affiliated Hospital of Hebei North University from January to December 2024. Patients were divided into sepsis with ARDS group and sepsis without ARDS group based on whether they developed ARDS within 72 hours after enrollment. In addition, healthy volunteers who underwent health check-ups at the hospital during the same period were selected as the controls. Demographic data including gender, age, Acute Physiology And Chronic Health Evaluation II (APACHE II) score, oxygenation index (PaO2/FiO2), and laboratory parameters were collected for each group, as well as the sites of infection for the septic patients. Serum levels of CREG and inflammatory markers [interleukin-6 (IL-6), tumor necrosis factor-\u03b1 (TNF-\u03b1), procalcitonin (PCT), and C-reactive protein (CRP)] were measured using enzyme-linked immunosorbent assay (ELISA). The differences in the above indicators were compared among groups. Multivariate Logistic regression analysis was used to identify independent influencing factors for sepsis complicated with ARDS. Receiver operator characteristic curve (ROC curve) was plotted to evaluate the predictive value of CREG for sepsis complicated with ARDS. 1) Cell experiment results: Compared with the blank control group, the expressions of Beclin1, LC3-II/LC3-I ratio, and CD206 were decreased in each LPS group [Beclin1 protein (Beclin1/\u03b2-actin): 0.32\u00b10.05 vs. 0.87\u00b10.09, LC3-II/LC3-I ratio: 0.41\u00b10.06 vs. 1.24\u00b10.11, CD206: (27.14\u00b13.52)% vs. (51.78\u00b15.91)%, all P<0.05], while p62 and CD86 expressions were increased [p62 protein (p62/\u03b2-actin): 1.58\u00b10.13 vs. 0.53\u00b10.07, CD86: (38.35\u00b14.67)% vs. (18.26\u00b13.24)%, both P<0.05]. CREG overexpression significantly improved the above autophagy and polarization indicators, whereas CREG interference further exacerbated these indicators (all P<0.05). 2) Clinical trial results: Ultimately, 40 patients were included in the sepsis with ARDS group, 60 in the sepsis without ARDS group, and 20 in the healthy control group. There were no statistically significant differences in gender, age among the three groups, nor in the distribution of infection sites between the sepsis with ARDS and sepsis without ARDS groups (all P>0.05). Compared with the healthy control group, the patients with sepsis showed aggravated systemic inflammatory burden. Compared with the sepsis without ARDS group, the sepsis with ARDS group exhibited more severe disease, with lower PaO2/FiO2 and CREG levels, and higher levels of inflammatory markers (all P<0.05). As APACHE II score increased, serum CREG levels decreased progressively while inflammatory marker levels increased progressively. Multivariate Logistic regression analysis showed that elevated APACHE II score and inflammatory markers were independent risk factors for sepsis complicated with ARDS [all odds ratio (OR) >1, all P<0.05], while elevated CREG was a protective factor [OR=0.385, 95% confidence interval (95%CI) was 0.344-0.432, P=0.015]. ROC curve analysis showed that the area under the ROC curve (AUC) of CREG for predicting sepsis complicated with ARDS was 0.806 (95%CI was 0.713-0.899); at the optimal cut-off value of 7.85 \u03bcg/L, the sensitivity was 71.43% and the specificity was 78.57%. CREG exerts a protective role in sepsis-induced ARDS by positively regulating alveolar macrophage autophagy activity and correcting M1/M2 polarization imbalance. Elevated serum CREG is a protective factor for sepsis complicated with ARDS and has early predictive value for sepsis-induced ARDS.\n\nID: 42563599\nTitle: 3D-BMSC Spheroids Enhance Bone Repair Associated with H-Type Vessels and Immunomodulation.\nAbstract: The therapeutic potential of bone marrow mesenchymal stem cells (BMSCs) in bone tissue engineering (BTE) is compromised by functional decline during conventional two-dimensional (2D) expansion. We hypothesized that chitosan film-based three-dimensional (3D) culture rejuvenates BMSC potency, synergistically promoting angiogenesis and immunomodulation for vascularized bone regeneration. Mouse BMSCs were cultured into spheroids on chitosan films. Their stemness, proliferation, migration, senescence, osteogenic, and proangiogenic potential were compared with 2D cultures. Paracrine effects were evaluated by treating human umbilical vein endothelial cells (HUVECs) and RAW264.7 macrophages with BMSC-conditioned medium (CM). In vivo, gelatin methacryloyl (GelMA) hydrogel-encapsulated 3D-BMSC spheroids were implanted into mouse critical-size cranial defects. Compared to 2D counterparts, 3D-BMSCs exhibited increased stemness, proliferation, migration, delayed senescence, osteogenic differentiation, and enhanced proangiogenic potential. We observed that conditioned medium from 3D-BMSCs (3D-CM) was associated with in vitro angiogenesis and orchestrated a proreparative microenvironment by promoting M2 macrophage polarization and suppressing M1 inflammation. In vivo, GelMA + 3D-BMSC spheroids achieved greater bone regeneration, which was accompanied by a proreparative immune microenvironment and enhanced CD31/EMCN-positive H-type-like vessel formation. This chitosan film-based 3D culture system effectively augments BMSC therapeutic potency, simultaneously enhancing intrinsic cell properties and orchestrating a proregenerative microenvironment, thereby offering a promising experimental platform for critical-sized bone defect repair.\n\nID: 42563507\nTitle: Single-Nucleus Transcriptome Analysis Provides New Insights Into B Chromosome Elimination in Sorghum.\nAbstract: B chromosomes are supernumerary entities found in many plant species, with some exhibiting tissue-specific elimination. In Sorghum purpureosericeum, extensive B chromosome elimination occurs during embryogenesis affecting most of the embryonic organs, leaving the B chromosome maintained mainly in limited regions of meristems. The dynamics of the process and rarity of the transcripts associated with elimination make capturing it challenging. To address this, we performed single-nucleus RNA sequencing (snRNA-seq) on embryos undergoing B chromosome elimination. This approach enabled detection of more B-linked transcripts compared to previous methods. Notably, we identified nuclei with B-specific transcripts, which predominantly clustered in a single cluster in both replicates of B-positive embryos. Further analysis of these clusters revealed three subpopulations with divergent transcriptional profiles. One subpopulation showed gene expression patterns suggesting active elimination of the B chromosome, while the other subpopulations are expected to exhibit regular segregation of the B chromosome and/or preparation for the elimination process. Our analysis provides resolution so far missing in current studies and highlights a clear benefit of the single-cell approaches for studying specific behaviour of the B chromosomes.\n\nID: 42563470\nTitle: Predictive Value of Imaging Indicators for Disease Progression in Acute Stanford Type B Aortic Intramural Hematoma Without Ulcer-like Lesions.\nAbstract: To investigate the clinical outcomes of acute Stanford type B intramural hematoma (TBIMH) without ulcer-like lesions following medical management and to identify predictors of disease progression. A retrospective analysis was performed on patients with acute TBIMH without ulcer-like lesions who received medical management. Patients were categorized into progression and nonprogression groups based on 1-year follow-up computed tomography angiography (CTA). Disease progression was defined as aortic rupture, aortic dissection, aortic enlargement (\u22655\u00a0mm), or hematoma thickening (\u22653\u00a0mm), while nonprogression was defined as complete/partial resolution or retention of the hematoma. A multivariate analysis identified the predictors of disease progression, and Kaplan-Meier curves were used to compare survival outcomes. A total of 110 patients (mean age 55.9\u00b110.5\u00a0y, 25 females) were included, with 21 patients (19.1%) showing disease progression. Multivariate analysis revealed that the maximum aortic diameter (MAD) (OR=7.6, P=0.003) and maximum CT value of the hematoma (CTmax) (OR=1.04, P=0.025) were independently associated with disease progression. The optimal cutoff values for MAD and CTmax were 40.0\u00a0mm (AUC: 0.69, sensitivity: 38.1%, specificity: 92.1%) and 71.9 HU (AUC: 0.68, sensitivity: 76.2%, specificity: 66.3%), respectively. When MAD and CTmax were combined, the AUC increased to 0.75 (sensitivity: 81.0%, specificity: 66.3%). A model based on MAD and CTmax effectively stratifies progression risk in TBIMH without ulcer-like lesions, facilitating early intervention in high-risk patients.\n\nID: 42563455\nTitle: S-layer (Glyco)protein lattices: Biophysical principles of antifouling at prokaryotic interfaces.\nAbstract: Surface layer (S-layer) lattices, composed of proteins and glycoproteins, constitute one of the most abundant and conserved supramolecular structures in the prokaryotic world. These self-assembling, two-dimensional arrays represent a major evolutionary investment, often accounting for up to 10% of total cellular protein synthesis. Despite enormous sequence diversity and adaptation to widely different ecological niches, S-layers persist across phylogeny, suggesting a fundamental selective advantage. In this review, we synthesize historical ultrastructural observations with modern atomic-resolution structural data and biophysical principles to demonstrate that antifouling is a general and fundamental function of all bacterial and archaeal S-layers. We argue that antifouling arises from a sophisticated synergy of lattice dynamics, crystalline nanotopography, electrostatic mosaicity, fragmented hydrophobicity, structured hydration shells and frequently glycan-mediated steric repulsion. We specifically place S-layer antifouling into the physical framework of life at low Reynolds numbers, where even minimal surface fouling imposes severe energetic penalties on nutrient acquisition and motility. We also highlight the S-layer as a tunable interface that suppresses non-specific fouling while precisely gating specific molecular interactions and community formation. Finally, we discuss how this universal biophysical strategy provides a powerful blueprint for biomimetic surface engineering in (nano)biotechnology, synthetic biology, and materials science.\n\nID: 42563416\nTitle: A 3D model of human hand anatomy using contrast imaging and muscle architecture visualization.\nAbstract: Diffusible iodine-based contrast-enhanced microCT (DiceCT) enables three-dimensional visualization of mineralized and soft tissues while preserving their spatial relationships in situ. We present a DiceCT-based digital atlas of a human hand from a consented female donor through the University of Missouri Gift of Body program, scanned at 48.8\u2009\u03bcm resolution following Lugol's iodine staining. Bones, tendons, intrinsic muscles, neurovascular structures, the flexor retinaculum and carpal tunnel, and dorsal digital expansions were manually segmented to generate labeled multiplanar sections and three-dimensional reconstructions. The dataset resolves epidermal ridge detail on the palmar surface while capturing structures, including the carpal tunnel contents, extensor mechanism, neurovasculature, palmar fat pads, and metacarpophalangeal sesamoids. Reconstructions demonstrate relevant relationships among the median nerve, flexor tendons, and flexor retinaculum, the ulnar nerve within Guyon's canal and the radial artery within the anatomical snuffbox. Distal digital arterial anastomoses are visible near the terminal tufts, and radial artery branches supplying the dorsal and distal scaphoid poles provide context for scaphoid vascular vulnerability. Muscle volumes and physiological cross-sectional areas were calculated using all fascicles within each intrinsic muscle. Flexor pollicis brevis and adductor pollicis exhibited comparatively large relative physiological cross-sectional areas, whereas the lumbricals had the smallest values, consistent with previous architectural estimates. By documenting whole-hand anatomy and within-individual muscle architecture non-destructively, this atlas provides a high-fidelity resource for anatomical education, documentation of anatomical variation, clinical interpretation, and generation of anatomically consistent biomechanical models. These results support DiceCT as a platform bridging anatomical research, clinical translation, and pedagogical access to donor-specific human anatomy.\n\nID: 42563401\nTitle: A multi-stage deep learning framework for half-detector truncation and metal artifact reduction in CBCT.\nAbstract: Cone-beam computed tomography (CBCT) is widely utilized for its high spatial resolution and compact design. However, image quality is often compromised in the half-detector (HD) geometry, where data truncation arising from the offset detector configuration coexists with metal artifacts caused by metallic implants. These artifacts interact synergistically, leading to severe image degradation that conventional correction methods fail to\u00a0address. We propose a multi-stage deep learning framework, HD-TMAR, to systematically decompose and correct combined truncation and metal artifacts in HD CBCT. The proposed framework adopts a multi-stage restoration strategy comprising three stages: (1) Sinogram Correction, which explicitly isolates the artifact residuals from the projection data and synergizes them with structural prior-normalized features to systematically suppress global truncation biases and metal artifacts; (2) Merging and Reconstruction, which employs a specialized overlapping patching and selective replacement strategy to accurately reconstruct the truncated regions and metal traces; and (3) Image Refinement, where ImgNet further enhances the reconstructed image to restore fine anatomical\u00a0textures. Experiments using realistic simulation datasets demonstrated that the proposed method achieved the highest qualitative fidelity and quantitative metrics compared to previous deep learning MAR methods. The framework effectively suppressed severe artifacts while preserving dental morphology, whereas comparative methods suffered from secondary artifacts or\u00a0blurring. HD-TMAR successfully disentangles complex artifact interactions. By synergizing sinogram-domain correction with image-domain refinement, the framework demonstrates promising potential for clinical application in enhancing the diagnostic performance of HD CBCT systems in the presence of metallic\u00a0implants.\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.

Lipin-1 is a multifunctional lipid-metabolic regulator that integrates cellular metabolism with inflammatory responses through its dual roles as a phosphatidic acid phosphatase enzyme and a transcriptional coregulator. However, its role in macrophage-driven atherosclerosis remains controversial. This review critically evaluates the domain-specific functions of lipin-1 and their impact on disease progression. Accumulating evidence indicates that lipin-1 exerts divergent, domain-dependent effects. The transcriptional coregulatory activity of lipin-1 promotes peroxisome proliferator-activated receptor/peroxisome proliferator-activated receptor \u03b3 coactivator 1-\u03b1 signaling, enhances fatty acid \u03b2-oxidation and oxidative phosphorylation, and supports interleukin-4-driven proresolving macrophage polarization. It also enhances efferocytosis, suppresses sterol regulatory element-binding protein-mediated lipogenesis, and reduces oxidized low-density lipoprotein-induced foam-cell formation. These effects are associated with reduced necrotic core formation, lower interleukin-23 signaling, diminished macrophage necroptosis, and improved plaque stability in experimental models. In contrast, the phosphatidic acid phosphatase enzymatic activity of lipin-1 activates diacylglycerol-dependent protein kinase C-extracellular signal-regulated kinase- activator protein-1 and toll-like receptor 4 signaling, promotes inflammatory eicosanoid production, enhances oxidized low-density lipoprotein uptake, impairs cholesterol efflux, and accelerates foam-cell formation and vascular inflammation. Myeloid-specific loss of phosphatidic acid phosphatase activity reduces lesion size and inflammatory burden while improving macrophage lipid handling. Collectively, current evidence supports a domain- and context-dependent role for lipin-1 in atherosclerosis. The transcriptional coregulatory function appears predominantly atheroprotective, whereas phosphatidic acid phosphatase enzymatic activity is proinflammatory and atherogenic. Selective modulation of lipin-1 activity in macrophages may therefore represent a promising therapeutic strategy to limit atherosclerosis progression while preserving inflammation-resolving pathways.\n --- END ACTUAL ABSTRACT FOR 42535557 ---\n\n- ERROR: You cited ID: 42520682 for the quote: \"Piezo1 exerted protective effects against hepatotoxin-induced liver necrosis and promoted liver recovery after APAP overdose... enhanced phagocytic activity by upregulating MerTK expression.\"\n FACT: Ellipses (...) are strictly forbidden.

Macrophages are critical elements in acute hepatic inflammation and resolution. Piezo1 is a mechanically activated ion channel that modulates innate immune responses and senses microenvironmental cues. The functions of myeloid Piezo1 in AILI remain elusive. This study aimed to determine whether myeloid Piezo1 regulates inflammation resolution and macrophage-mediated clearance during AILI. To generate the AILI mouse model, APAP was administered intraperitoneally to Piezo1fl/fl and Piezo1\u0394LysM mice, and samples were collected at 6, 24, and 48\u00a0h after treatment. Bone marrow-derived macrophages (BMDMs) were stimulated with APAP-treated normal mouse liver cell line (AML12) supernatant to mimic sterile inflammatory response. Liver histology, immunostaining, gene expression analysis, flow cytometry, intracellular Ca2+ measurements, and phagocytosis/efferocytosis assays were performed. Piezo1 exerted protective effects against hepatotoxin-induced liver necrosis and promoted liver recovery after APAP overdose. In vitro assays revealed that Piezo1 alleviated the inflammatory response in bone marrow-derived macrophages. Mechanistically, myeloid Piezo1 manifested a more reparative phenotype and enhanced phagocytic activity by upregulating MerTK expression. Specifically, Piezo1 acted through Ca2+ influx to regulate the expression of MerTK at the target binding stage. Inhibition of MerTK induced more pro-inflammatory mediators and reduced phagocytic ability, phenocopying the Piezo1 deficiency. Separately, Piezo1 modulated cytoskeletal rearrangement via the FAK/Rac1 axis during target internalization. Pharmacological activation of Piezo1 promoted pro-resolution marker expression and enhanced efferocytosis/phagocytic clearance in vitro. This study identified myeloid Piezo1 as an important regulator of macrophage-mediated inflammation resolution and dying-cell clearance during AILI, providing a basis for future exploration of Piezo1-related pathways in macrophage-mediated liver recovery.\n --- END ACTUAL ABSTRACT FOR 42520682 ---\n\n- ERROR: You cited ID: 42554595 for the quote: \"redirecting monocyte differentiation offers a compelling yet underexplored therapeutic opportunity...

Redirecting monocyte differentiation offers a compelling yet underexplored therapeutic opportunity. In this work, we found M1-polarized macrophage-derived extracellular vesicles (M1-EVs) efficiently induced monocytes to differentiate into anti-tumor macrophages via tumor necrosis factor alpha (TNF-\u03b1)-mediated signaling. Despite promising, the therapeutic efficacy of M1-EVs was constrained by insufficient glioma accumulation and CD47-mediated phagocytic inhibition. To address this challenge, we further engineered M1-EVs with dual-targeting specificity by genetically incorporating a tumor-directed chimeric antigen receptor (CAR) against IL13R\u03b12 or EGFRvIII together with CD47-blocking SIRP\u03b1 variants. The resulting dual-targeting EVs (M1-CS-EVs) exhibited enhanced blood-brain barrier (BBB) penetration and glioma accumulation while locally disrupting CD47-SIRP\u03b1 interactions. In three orthotopic glioma models, M1-CS-EVs elicited a potent anti-tumor immune response and enhanced tumor phagocytosis, significantly suppressing tumor growth while prolonging animal survival. Our findings establish a platform technology for directing monocyte differentiation toward anti-tumor phenotypes, offering a broadly applicable strategy for glioma treatment.\n --- END ACTUAL ABSTRACT FOR 42554595 ---\n\n- ERROR: You cited ID: 42558045 for the quote: \"Gas-6 increased the clearance of anionic phospholipid-expressing microparticles from circulation by coupling microparticles with macrophages and monocytes... to facilitate phagocytosis\"\n FACT: Ellipses (...) are strictly forbidden.

These microparticles induce a systemic hypercoagulable state that rapidly transitions into secondary coagulopathy and endotheliopathy. We hypothesize that removing these microparticles from circulation could mitigate the TBI-induced secondary pathologies and improve outcomes. In this study, we investigated the role of Gas-6 (growth arrest-specific 6) as a scavenging factor for microparticles. We quantified plasma Gas-6 levels in a mouse model of TBI and administered exogenous Gas-6 either before or after TBI to evaluate its effects on endotheliopathy, coagulopathy, and outcomes. Mechanistic studies assessed Gas-6-mediated clearance of circulating microparticles in TBI mice and investigated the molecular interactions by which Gas-6 binds microparticles and macrophages to facilitate microparticle scavenging. We found that plasma levels of Gas-6 were significantly reduced in mice subjected to severe TBI. Exogenous Gas-6 given either preinjury or postinjury attenuated coagulopathy, protected the integrity of the cerebral and pulmonary endothelium, improved neurological recovery, and increased overall survival of TBI mice. Gas-6 increased the clearance of anionic phospholipid-expressing microparticles from circulation by coupling microparticles with macrophages and monocytes through the \u03b3-carboxyglutamate and the LG1 (laminin G-like domain 1), respectively, to facilitate phagocytosis of microparticles in the liver. These findings demonstrate the therapeutic potential of Gas-6 for TBI and potentially for other acute pathologies, in which microparticles initiate and propagate coagulation dysfunction and endothelial injuries.\n --- END ACTUAL ABSTRACT FOR 42558045 ---\n\n- ERROR: You cited ID: 42554604 for the quote: \"hyperglycemia induces inflammatory PANoptosis in CD4+ T cells from patients... resulting from elevated glucose driving the accumulation and release of succinate from monocytes\"\n FACT: Ellipses (...) are strictly forbidden.

In a two-center cohort of patients undergoing total aortic arch replacement, we identify stress hyperglycemia as an independent determinant of poor postoperative outcomes that associates strongly with CD4+ T cell loss. Hyperglycemia induces inflammatory PANoptosis in CD4+ T cells from patients in response to surgical trauma. This results from elevated glucose driving the accumulation and release of succinate from monocytes, which subsequently acts on CD4+ T cells to compromise mitochondrial integrity and activate ZBP1-mediated PANoptosis. Our findings define a monocyte-T cell metabolic signaling axis that transduces hyperglycemic stress via elevated succinate to adaptive immune cell death and reveal potential therapeutic targets to prevent postoperative immune dysfunction and organ injury, especially for patients with hyperglycemic comorbidities.\n --- END ACTUAL ABSTRACT FOR 42554604 ---\n\n- ERROR: You cited ID: 42564235 for the quote: \"CSE enhanced bacterial invasion of THP-1 macrophages and impaired neutrophil phagocytosis, reducing bacterial uptake by 17.8% and 29.9% after 30 and 60 min, respectively.\"\n FACT: Quote was found in context but NOT in the specific abstract mapped to ID '42564235'.\n \n Below is the complete, true text of ID 42564235 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 42564235 ---\n ID: 42564235\nTitle: Vagus nerve-driven microbiota homeostasis: a promising integrative add-on therapy for neurodevelopmental disorders.\nAbstract: Over the past two decades, the conceptualization of neurodevelopmental disorders (NDDs) has undergone a profound transformation, shifting from a primarily brain-centric framework toward a systems-level perspective that integrates peripheral physiological processes. Among these, the gut microbiota has emerged as a critical determinant of neurodevelopmental trajectories. Through its involvement in immune modulation, metabolic signaling, and neural communication, the microbiota-gut-brain axis (MGBA) exerts a pervasive influence on brain maturation and function. A growing body of evidence indicates that early-life disruptions of microbiota composition-commonly referred to as dysbiosis-are associated with an increased risk of NDDs, including autism spectrum disorder (ASD), attention-deficit/hyperactivity disorder (ADHD), and epilepsy. These disruptions are frequently driven by environmental exposures such as antibiotic use, cesarean delivery, dietary patterns, and psychosocial stress. Despite the expanding recognition of these associations, current therapeutic strategies aimed at restoring microbiota balance, including probiotics and fecal microbiota transplantation, have yielded inconsistent and often transient results. In this context, Vagus Nerve Stimulation (VNS), particularly in its non-invasive forms (nVNS), has emerged as a promising approach capable of modulating environmental exposures through the host-centered regulatory mechanisms of the MGBA. By influencing autonomic tone, activating the cholinergic anti-inflammatory pathway, and modulating neurotransmitter systems, nVNS may restore microbiota homeostasis while simultaneously improving neurodevelopmental outcomes. This article provides a comprehensive and integrative review of the mechanistic, preclinical, and clinical evidence supporting the role of nVNS as a microbiota-modulating intervention. We further discuss its potential as a safe, cost-effective and promising therapeutic strategy for neurodevelopmental disorders, with a particular emphasis on pediatric populations.\n --- END ACTUAL ABSTRACT FOR 42564235 ---\n\n\n\u2705 PASSED (DO NOT CHANGE THESE):\n- \"A2AR activation promoted microglial efferocytosis of apoptotic cells and myelin debris in the lesioned white matter\" (Source: 42550891)\n- \"A2AR signaling engaged HIF1\u03b1-dependent metabolic reprogramming to increase glycolysis, thereby providing the energetic support required for efficient and sustained efferocytosis.\" (Source: 42550891)\n- \"Compared with the ox-LDL group, the HLJDD and simva groups showed increased LAPosome percentage and enhanced apoptotic cell clearance\" (Source: 42543371)\n- \"IL-33 promotes MerTK expression, critical for efferocytosis by macrophages, by a process associated with an early rapid local increase in IL-13 production\" (Source: 42558291)\n- \"By three independent functional assays, we demonstrate that endogenous and exogenous cochlin LCCL domain enhances macrophage efferocytosis\" (Source: 42555352)\n- \"Gpr146 ablation potentiated microglial A\u03b2 phagocytosis, which correlated with the transcriptional upregulation of phagocytic receptors\" (Source: 42554945)\n- \"hemophagocytic lymphohistiocytosis (HLH), a hyperinflammatory syndrome characterized by exaggerated immune activation and macrophage activation manifested by phagocytosis of hematopoietic cells\" (Source: 42558661)\n- \"M\u03c6Smart reprogrammed macrophage injection into ApoE-/- mice alleviated inflammation locally in the plaque and liver.

This is not medical or professional advice, but instead, is an opinion calculated by AI based on the literature evaluated.\n\n###[CLAIM EVALUATED AND ANSWER TO USER]\n\"Restoration of efferocytosis is highly dependent on macrophage polarization states; M1 and M2 phenotypes can both contribute to resolution if metabolic cues are corrected.\"\n\n### [ABSTRACT & REWRITTEN CLAIM]\nScientific investigation into the restoration of efferocytic efficiency indicates that while M1 and M2 classifications serve as historical proxies for macrophage function, the actual capacity for apoptotic cell clearance is contingent upon metabolic and signaling status rather than a fixed phenotypic designation. Evidence supports that modulation of specific pathways (e.g., A2AR, MerTK, JAK/STAT, and mitochondrial metabolism) can enhance efferocytosis across diverse states.\n\n### [INTRODUCTION & JUSTIFICATION]\nThe paradigm of macrophage polarization as a binary M1/M2 system is increasingly superseded by the recognition of a functional continuum dictated by metabolic plasticity. Efferocytosis is an energy-demanding process that requires specific signaling cues, such as those initiated by IL-33 or Gas-6, and metabolic support, such as HIF1\u03b1-dependent glycolysis. While inflammation-associated (M1-like) macrophages are traditionally viewed as pro-inflammatory, evidence demonstrates that they can be reprogrammed to exhibit enhanced efferocytosis through targeted interventions. For instance, A2AR activation promotes efferocytosis to accelerate repair, and the induction of specific receptors like MerTK allows for the efficient engulfment of debris, bridging the gap between pro-inflammatory states and the resolution of inflammation.\n\n### [DISCUSSION: NOVEL & OVERLOOKED]\n* Efferocytosis acts as a primary resolution driver that can be pharmacologically bolstered, even in chronic inflammatory states, through the activation of specific ion channels like Piezo1.\n* Metabolic sensors like A2AR link microenvironmental triggers to the cellular machinery required for myelin and apoptotic cell clearance.\n* The expression of CD3 on macrophages, traditionally a T-cell marker, suggests a previously uncharacterized layer of complexity in how myeloid cells integrate signaling pathways during stress.\n* Natural polysaccharides show potential in metabolic regulation of macrophages, influencing polarization and inflammatory output through the modulation of pathways like NF-\u03baB and MAPK.\n* Circulating cochlin LCCL domain serves as an exogenous efferocytosis-promoting factor, highlighting the role of systemic serum proteins in local tissue repair.\n* Fetal sex significantly shapes maternal monocyte metabolic programming, with pEVs inducing sex-dependent shifts in efferocytic activity.\n* Non-functional isoforms of P2X7 in cancer cells reveal how malignant cells bypass the regulated scavenger receptor pathways typically used by macrophages.\n\n### [EVIDENCE, METHODOLOGY & CITATIONS]\n1.

Currently, there are few approved clinical therapies that specifically target white matter repair to enhance functional recovery after stroke. We demonstrated that microglial adenosine 2A receptor (A2AR) is essential for spontaneous white matter regeneration after ischemic injury in mice. Deletion of A2AR in microglia specifically impaired chronic-phase repair without altering the severity of acute ischemic injury. Pharmacological activation of A2AR signaling with blood-brain barrier-permeable agonistic micelles during the early reperfusion phase enhanced white matter structural repair and led to sustained improvements in cognitive and sensorimotor function in mice. Mechanistically, A2AR activation promoted microglial efferocytosis of apoptotic cells and myelin debris in the lesioned white matter, thereby limiting secondary necrosis-induced inflammation, enhancing neurotrophic factor release, and establishing a reparative microenvironment conducive to oligodendrocyte precursor cell differentiation and remyelination. Moreover, A2AR signaling engaged HIF1\u03b1-dependent metabolic reprogramming to increase glycolysis, thereby providing the energetic support required for efficient and sustained efferocytosis. Together, these findings identify A2AR as a critical regulator of microglia-mediated white matter repair and a promising therapeutic target for enhancing regeneration after stroke."

Here, we found that the mechanosensitive ion channel Piezo1 was up-regulated in hepatic fibrosis. Macrophages lacking Piezo1 showed sustained inflammation and impaired spontaneous resolution of early liver fibrosis. Further analysis revealed an impairment of clearance of apoptotic cells by macrophages in the fibrotic liver. Macrophages showed enhanced efferocytosis when cultured on rigid substrates but not soft ones, suggesting stiffness-dependent efferocytosis of macrophages required Piezo1 activation. Besides, Piezo1 was involved in the efficient acidification of the engulfed cargo in the phagolysosomes and affected the subsequent expression of anti-inflammation genes after efferocytosis. Pharmacological activation of Piezo1 increased the efferocytosis capacity of macrophages and accelerated the resolution of inflammation and fibrosis.

However, concurrent immunosuppression may compromise vaccine efficacy. This study investigated the effect of immunosuppression induced by either chicken anaemia virus (CAV) or infectious bursal disease virus (IBDV), administered prior to or following vaccination with the M. gallisepticum live vaccine strain ts-304 (Vaxsafe MG304), on tracheal host responses to subsequent challenge with virulent M. gallisepticum. Tracheal responses were assessed by genome-wide transcriptional profiling in these groups and compared across unvaccinated-unchallenged, unvaccinated-challenged, vaccinated-unchallenged and vaccinated-challenged groups that had not been exposed to CAV or IBDV. Immunosuppression resulted in significant differences in tracheal transcriptional responses compared to immunocompetent groups, irrespective of the timing of infection with CAV or IBDV. Differences in transcription were more pronounced in the IBDV-infected groups than the CAV-infected groups. Functional interrogation of differentially transcribed genes revealed adverse effects of M. gallisepticum on extracellular and intracellular signalling, cell communication, cellular actin dynamics, formation of the cellular cytoskeleton, and cellular metabolic pathways in the tracheal mucosa of immunosuppressed groups. In addition, there were indications of down-regulation of both innate and adaptive immune responses, including cytokine signalling, antigen processing presentation, and immune cell receptor signalling in the immunosuppressed groups. Specifically, findings indicated that infection with CAV impaired pro-inflammatory and adaptive T-cell responses in the tracheal mucosa. The findings implied that the primary immune response induced post-vaccination and the secondary immune response induced post-challenge with virulent M. gallisepticum were both affected by infection with these two viruses. Coupled with previous observations of reduced antibody titres against M. gallisepticum, and increased rates of recovery of virulent M. gallisepticum in both CAV- and IBDV-infected groups, the significant transcriptional changes detected in the current study highlighted the roles of both cell-mediated (CMI) and humoral immunity (HI) in vaccine-induced protection, as CAV mainly affects CMI and IBDV mainly affects HI. These findings will assist in identifying the mechanisms underlying the reduced efficacy of live attenuated mycoplasma vaccines in immunosuppressed animals."

Class I myosins Myo1e and Myo1f (Myo1e/f) have been implicated in linking the plasma membrane to the actin network, but their specific roles during Fc-receptor-mediated phagocytosis remain unclear. Using CRISPR-edited RAW 264.7 macrophages lacking Myo1e and Myo1f, we show that double knockout (dKO) cells exhibit markedly reduced uptake of IgG-coated beads, a phenotype that is partially rescued by re-expression of either myosin. Lattice-light-sheet and confocal imaging revealed distinct F-actin architectures corresponding to the various stages of cup progression, including basal podosome-like adhesions, individual phagocytic podosomes (actin teeth) along the rim of the cup, and a contractile phagocytic ring formed by the reorganization of podosomes into a higher-order network. In Myo1e/f-deficient cells, podosome formation was diminished, actin teeth were largely absent, and the phagocytic ring formed prematurely, which was often accompanied by stalled cup progression and repeated engulfment attempts. Myo1e/f localized both to podosomes and to the inner surface of the phagocytic ring, non-muscle myosin II (NM2) localized to the outer surface, and the absence of Myo1e/f correlated with the diffuse distribution of NM2. In addition, Myo1e/f-deficient macrophages exhibited increased trogocytosis of antibody-opsonized HL-60 cells, indicating a shift from whole-target engulfment toward partial target ingestion. These results suggest that Myo1e/f coordinate spatial and temporal transitions between protrusive and contractile actin networks, thereby ensuring efficient phagocytic cup progression. Our findings highlight a dual role for Myo1e/f in adhesion regulation and force balance during macrophage phagocytosis."

"abstract_text": "ID: 40741709\nTitle: Depletion of endomembrane reservoirs drives phagocytic appetite exhaustion in macrophages.\nAbstract: During phagocytosis, a phagocytic cup grows via F-actin remodeling and localized secretion to entrap a particle within a phagosome, which then fuses with endosomes and lysosomes to digest the particle, followed by phagosome resolution. As spatially limited systems, phagocytes have a maximal phagocytic capacity, at which point further uptake must be reduced. However, the processes responsible for phagocytic appetite exhaustion as phagocytes reach their maximal phagocytic capacity are poorly defined. We found that macrophages at their capacity have lower surface levels of Fc\u03b3 receptors but overexpression of these receptors did not increase their capacity, suggesting that receptor levels are not limiting. We found that surface membrane in-folding, membrane tension and cortical F-actin were all reduced in exhausted macrophages. Although this might contribute to appetite suppression, we also found that 'free' endosomes and lysosomes were severely depleted in exhausted macrophages. Consequently, focal exocytosis at sites of externally bound particles was reduced. In comparison, macrophages recovered their appetite if phagosome resolution was permitted. We propose that depletion of the endomembrane pools is a major determinant of phagocytic fatigue as macrophages reach their phagocytic capacity."

During phagocytosis, macrophages internalize and degrade pathogens and apoptotic cells by forming the phagocytic cup and phagosome. Osteoclasts resorb bone by forming the sealing zone and ruffled border at the ventral membrane. This review explores the organizational principles of these dynamic structures. In in vitro frustrated phagocytosis, specifically 2D phagocytosis by macrophages, the activation of the Fc\u03b3 receptor generates multiple self-organized waves containing F-actin, Arp2/3, and phosphoinositides. The propagation of these circular actin waves segregates the inside from the outside, leading to the compartmentalization of the ventral membrane. As the actin wave passes, cortical actin is disrupted, and membrane remodeling occurs within the wave, creating a new membrane domain with high exocytic activity. These processes mirror the formation of the constriction zone in the phagocytic cup and phagosome during 3D phagocytosis. A similar mechanism may also contribute to the formation of the sealing zone and ruffled border in osteoclasts. Based on these observations, we propose that dynamic structures formed from actin waves are organized through the fractal integration of self-organized, oscillatory substructures, with F-actin treadmilling fueling their formation and maintenance."

While a number of mathematical models have been developed to describe this process, they often overlook membrane tension, a key physical parameter known to influence membrane deformation and cytoskeletal behaviour. To address this gap, we present an enhanced mathematical model of receptor motion during phagocytosis that explicitly incorporates the role of membrane tension. Further, we introduce a signalling component that is coupled to receptor dynamics via the membrane tension. We find that including tension results in fundamentally different engulfment behaviour, which is slower than that predicted by models without tension. In particular, unlike in the previous version of this model, we show that tension can lead to stalled engulfment, an experimentally-observed phenomenon known as frustrated phagocytosis. We also find that signalling is able to modify engulfment behaviour, especially at later stages, and is able to alter cup growth to become linear in time without the need for receptor drift as introduced in previous models. These findings offer new insights into the role of membrane tension and biophysical regulation in phagocytosis, with implications for immune function, cell motility and targeted drug delivery."

Syk owns two SH2 domains that interact with biphosphorylated ITAMs of the Fc\u03b3R upon phagocytosis. This results in the activation of Syk by autophosphorylation, triggering phosphorylation of several downstream targets, F-actin polymerization, and phagocytosis of the IgG-opsonized target. We found that Syk is S-acylated upon phagocytosis by macrophages. Palmitoylation is performed on a single Syk-Cys by the DHHC5 enzyme that specifically associates with Syk upon phagocytosis. Syk palmitoylation is important for Syk localization to the phagocytic cup, phosphorylation, and phagocytosis. We observed that another Syk-Cys residue, within a redox motif, is modified by sulfenylation. Nevertheless, Syk desulfenylation seems to occur during phagocytosis, when H2O2 production at the cup decreases, after 3.5 min of phagocytosis. Molecular dynamics studies indicated that desulfenylation increased the exposure of a loop within the Syk interdomain B. This could facilitate phosphorylation of key Syk-Tyr residues by upstream kinases. We thus propose an updated model for Syk activation during Fc\u03b3R-mediated phagocytosis that involves both Syk palmitoylation and desulfenylation."

"abstract_text": "ID: 41071099\nTitle: Mechanosensitive ion channels as novel targets in osteoporosis.\nAbstract: Osteoporosis is the most prevalent metabolic bone disease globally, leading to an increased risk of fractures. Recent advances in ion channel research have shed light on the importance of mechanosensitive ion channels as novel players in these pathophysiological processes. This perspective discusses the involvement of the mechanosensitive ion channels TREK-1, Piezo, and volume-regulated anion channels (VRACs) as potential novel pharmacological targets for the treatment of osteoporosis. TREK-1, a mechanosensitive K2P channel is important for maintaining the resting membrane potential in many cells, including osteoblasts and osteoclasts. K2P channels regulate osteoblast proliferation and differentiation, as well as osteoclast activity, potentially modulating bone remodeling in osteoporosis. Piezo channels influence osteoblast differentiation and osteoclast activity by modulating calcium influx, which is crucial for osteogenic signaling pathways, such as Wnt/\u03b2-catenin and ERK1/2. Piezo1 activation promotes bone formation, while its deficiency leads to impaired osteogenesis and increased bone resorption. Volume-regulated anion channels have been shown to be involved in osteoblast adaptation to mechanical stress and macrophage polarization, which indicates their importance for bone homeostasis. Chronic inflammation is a major contributor to osteoporosis progression. Evidence of ion channel involvement in this process has emerged in recent years. Specifically, macrophage function in osteoporosis seems to be linked to ion channel activity. Inflammatory polarization of macrophages is a key player in inflammation-induced bone loss and can be driven by mechanosensitive ion channels. Modulating these ion channels may provide new therapeutic opportunities. Given the complexity of ion channel interactions in bone cells and their regulatory role in bone remodeling, understanding their precise function in osteoporosis is essential. Targeted modulation of mechanosensitive ion channels holds promise as a novel therapeutic approach to mitigate inflammation-driven bone loss and improve bone density. Further research into their role in osteoclasts and macrophage-driven bone degradation will aid in developing innovative osteoporosis treatments. Osteoporosis is the most common bone disease worldwide. The exact reasons for why bones weaken is often not fully understood, which makes the development of targeted therapies difficult. Our article highlights a new perspective: certain proteins in bone cells, called mechanosensitive ion channels, may be key players in osteoporosis. These channels act like tiny \u201cgates\u201d in the cell membrane that open when cells are stretched, thereby regulating the activity of cells. They help bone cells and immune cells sense their environment and respond to changes. We focus on three groups of these channels: K2P channels influence how bone-building cells (osteoblasts) grow and how immune cells control inflammation. Piezo channels help bone cells sense mechanical forces and control immune cell behavior. Volume-regulated anion channel channels may help bone cells adapt to stress and regulate inflammatory signals. Because of their dual effect on mechanical and inflammatory signaling, changes/alterations in ion channel activity may contribute to bone loss in osteoporosis. Pharmacological targeting of these channels could therefore help to protect bone. Early studies suggest that drugs influencing mechanosensitive ion channels might one day prevent or slow down osteoporosis. More research is needed, but this approach opens exciting new possibilities for treatment."

The lung is an attractive site for local intervention because it is directly accessible and immunologically specialized. However, effective pulmonary delivery is constrained by mucociliary clearance, airway mucus, alveolar macrophage uptake, and epithelial barriers. Nanomaterials can be rationally engineered to address these constraints, increasing pulmonary retention and concentrating immunotherapeutics within the lung tumor microenvironment while reducing systemic burden. This Review summarized the key physiological barriers for pulmonary immunotherapeutic delivery and discusses how nanomaterial properties shape deposition, retention, cellular partitioning, and downstream immune activation. We critically evaluate representative inhalable platforms across major immunotherapeutic modalities, including vaccines, immune checkpoint blockade, innate immune agonists (e.g., STING agonists), cytokine regulation, and emerging in situ immune-cell engineering strategies. We also highlight translational considerations. Together, these advances support inhalable immunotherapeutic nanomedicines as a complementary approach to current lung cancer treatment and a broader framework for pulmonary immune modulation."

Inspired by these bio-geometries, we explore how nanoscale anisotropy can be engineered to control the dynamic transport and biodistribution of synthetic nanocarriers in the body. We fabricate anisotropic silica nanocapsules with precisely tunable asymmetry to dissect shape effects on nano-bio interactions under physiological flow. Under shear flow in vitro, increasing anisotropy markedly reduced cellular uptake, whereas this effect was much less pronounced under static conditions, revealing strong flow-shape coupling. In vivo, highly anisotropic nanocapsules exhibit prolonged circulation, with a 2.8-fold longer half-life than spherical counterparts and significantly reduced sequestration by the liver, spleen, and circulating blood cells. Mechanistic analyses attributed these effects to decreased phagocytic internalization by Kupffer cells, splenic macrophages, and circulating monocytes. Computational fluid dynamics simulations corroborated this phenomenon, demonstrating that greater anisotropy shifts particle trajectories away from vessel walls toward the central flow stream, lowering the chances of cellular interception. Together, these results establish nanoscale anisotropy as a critical determinant of nanoparticle transport, immune recognition, and clearance under flow. Anisotropy engineering therefore provides a nature-inspired framework for designing long-circulating, immune-evasive nanocarriers with improved therapeutic performance."

Here, we investigated the neuroimmune effects of polystyrene NPs (100, 200, and 1000nm; 10 and 100\u03bcg/mL) across neuronal (SH-SY5Y, PCNs) and immune cells (THP1, macrophages). Cellular responses were assessed through analyses of cytotoxicity, immunocytochemistry and cytokine profiling. NPs exposure did not induce acute cytotoxicity but promoted persistent intracellular retention accompanied by lysosomal dysfunction, dysregulated autophagic flux, ER stress, and constrained mitochondrial function, thereby inducing a sublethal multi-organelle stress response. Macrophages exhibited greater vulnerability consistent with phagocytic burden, while inflammatory challenge further enhanced NPs uptake, reinforcing intracellular persistence. In contrast, neurons showed limited extracellular cytokine secretion yet accumulated intracellular IL-1\u03b2, suggesting low-grade inflammatory activation. Such responses were recapitulated in PCNs, supporting translational relevance across neuronal models. The cumulative nature of these observations suggests that NPs exposure may give rise to previously unrecognized accumulation-related pathologies, a phenomenon we term \"plasticoma\" as a conceptual framework, to describe the preferential deposition of non-degradable plastic particles within cells, to frame and stimulate future investigations into NP accumulation and pathology. These findings position NPs as potential determinant of neuroimmune dysfunction and highlight the importance of strategies aimed at mitigating their biological accumulation."

Emerging evidence highlights the intricate interplay between metabolic reprogramming and epigenetic modifications in macrophages, neutrophils, and other innate immune populations within the tumor microenvironment. Tumor-derived metabolites, hypoxia, and nutrient availability dynamically regulate chromatin accessibility, histone modifications, and DNA methylation patterns, thereby driving context-dependent immune phenotypes. Notably, metabolic rewiring can imprint long-lasting epigenetic changes, a phenomenon known as innate immune memory, which alters subsequent immune responses. Here, we discuss how key metabolic pathways, including glycolysis, fatty acid oxidation, and amino acid metabolism, govern innate immune cell fate and function via epigenetic mechanisms. We also highlight recent advances in epigenomic profiling that have unveiled distinct chromatin landscapes associated with innate immune dysfunction across cancer types. Finally, we explore emerging therapeutic strategies that target the metabolic-epigenetic axis to restore innate immune surveillance and enhance immunotherapy efficacy.

"abstract_text": "ID: 42564178\nTitle: Metabolic immune checkpoints in cancer: how tumor-derived metabolites shape immunotherapy resistance.\nAbstract: Immune checkpoint blockade has transformed cancer therapy, yet many tumors remain intrinsically resistant or acquire resistance after initial response. Increasing evidence indicates that this failure is not determined solely by PD-1, PD-L1, CTLA-4, or T-cell exhaustion, but also by metabolically suppressive states within the tumor microenvironment. Tumor-derived metabolites can function as metabolic immune checkpoints by limiting effector immune activity, promoting regulatory or myeloid suppressive compartments, and weakening immunotherapy efficacy. This mini review summarizes recent experimental evidence showing how lactate, adenosine, tryptophan-derived metabolites, and nucleotide-derived metabolites shape immune escape and resistance to immune checkpoint blockade. Lactate links tumor glycolysis to Treg recruitment, impaired T-cell function, and lactylation-associated therapeutic resistance. The CD73-adenosine axis suppresses CD8+ T cells and natural killer cells while reinforcing regulatory and myeloid immune programs. Tryptophan-derived metabolites extend beyond the classical IDO1-kynurenine-AhR pathway to involve non-classical checkpoints such as Siglec-15 and broader kynurenine/indole/serotonin networks. Emerging evidence further identifies nucleotide-derived UDP signaling as a driver of macrophage-mediated immunosuppression. Finally, we discuss how targeting metabolic checkpoints in combination with immune checkpoint blockade may improve therapeutic responses. Defining the spatial and cellular contexts of metabolite-mediated immune suppression may enable more precise strategies to overcome immunotherapy resistance."

Waist-to-BMI ratio (WBR) may better reflect adverse body composition. We examined cross-sectional and longitudinal associations between WBR and musculoskeletal disorders in T2DM. This two-phase study was conducted within an ongoing hospital-based cohort at the First Affiliated Hospital of Fujian Medical University (Fuzhou, China). The cross-sectional analysis included 4157 adults with T2DM recruited between March 2012 and August 2023 (54.3% men; mean age 59.4\u2009\u00b1\u200910.3\u2009years), using data from their first assessment. Associations of waist circumference (WC), waist-to-height ratio (WHtR), waist-to-hip ratio (WHR), BMI and WBR with osteopenia, sarcopenia, sarcopenic osteopenia (SOs), sarcopenic obesity (SOb) and fractures were evaluated. The prospective cohort comprised a longitudinal subset enrolled between March 2012 and June 2022, ensuring at least 1\u2009year of follow-up prior to administrative censoring in August 2023. A total of 440 individuals (57.0% men; mean age 59.7\u2009\u00b1\u20099.7\u2009years) were followed for a median of 34.0\u2009months (20.0-57.0). Associations between time-dependent WBR and incident outcomes were assessed using Cox models. A nested exploratory analysis was conducted within the cohort. Thirty participants with extreme annualised WBR change (\u0394WBR/yr) were selected. Baseline serum samples collected at enrolment, prior to outcome occurrence, were analysed using phage immunoprecipitation sequencing (PhIP-Seq). Cross-sectionally, WBR was negatively correlated with bone mineral density and appendicular skeletal muscle mass index and positively correlated with osteopenia, sarcopenia, SOs, SOb and fractures (all p\u2009<\u20090.01), whereas BMI, WC, WHtR and WHR showed weaker associations. After adjustment, higher WBR was independently associated with osteopenia (men: OR 1.723, 95% CI 1.614-1.840; women: OR 1.420, 1.348-1.495), sarcopenia (men: OR 4.779, 4.165-5.484; women: OR 2.991, 2.683-3.334), SOs (men: OR 6.261, 5.314-7.377; women: OR 4.336, 3.753-5.010), SOb (men: OR 4.737, 3.975-5.646; women: OR 4.652, 3.715-5.825) and fractures (men: OR 1.236, 1.093-1.397; women: OR 1.103, 1.003-1.213; all p\u2009<\u20090.05). Prospectively, higher time-dependent WBR predicted incident osteopenia (HR 1.365, 95% CI 1.024-1.820), sarcopenia (HR 1.282, 1.086-1.512), SOs (HR 1.408, 1.176-1.686), SOb (HR 1.634, 1.262-2.116) and fractures (HR 1.369, 1.029-1.821). PhIP-Seq analysis identified differential autoantibody reactivity related to muscle structural organisation and cytoskeletal regulation, while bone-related differences were enriched in Wnt signalling and hormone-related pathways. Higher WBR and longitudinal increases were independently associated with osteopenia, sarcopenia, sarcopenic phenotypes and fractures in individuals with T2DM."

Myosin motor functions are regulated by adaptor proteins that mediate cargo attachment and motor recruitment. To define the MYO1F interactome, we used in situ proximity labelling and proteomics in human myeloid cells. We identified a distinct SH3-domain-dependent adaptor module comprising CD2AP, ASAP1, SH3BP2 and SH3KBP1 (herein termed the CASS group of proteins). Interestingly, CD2AP is an Alzheimer's disease (AD) risk gene upregulated in the microglia of individuals with AD, which are implicated in phagocytic responses to amyloid-\u03b2. Structural modelling and mutagenesis confirmed multivalent proline-rich motif interactions between the CASS group of proteins and the MYO1F SH3 domain. Additional binding partners associate with the MYO1F pleckstrin homology (PH) domain. Immunofluorescence revealed colocalisation of MYO1F and the CASS group of proteins at actin-rich podosomes and phagocytic cups in macrophages and microglia. Functional assays demonstrated that MYO1F recruitment to the phagocytic cup requires motor activity and intact PH and SH3 domains. We provide the first MYO1F interactome identifying adaptor proteins for MYO1F in podosomes and during phagocytosis, offering new insights into its function in disease-associated microglia during neurodegeneration."

Here, we found that the mechanosensitive ion channel Piezo1 was up-regulated in hepatic fibrosis. Macrophages lacking Piezo1 showed sustained inflammation and impaired spontaneous resolution of early liver fibrosis. Further analysis revealed an impairment of clearance of apoptotic cells by macrophages in the fibrotic liver. Macrophages showed enhanced efferocytosis when cultured on rigid substrates but not soft ones, suggesting stiffness-dependent efferocytosis of macrophages required Piezo1 activation. Besides, Piezo1 was involved in the efficient acidification of the engulfed cargo in the phagolysosomes and affected the subsequent expression of anti-inflammation genes after efferocytosis. Pharmacological activation of Piezo1 increased the efferocytosis capacity of macrophages and accelerated the resolution of inflammation and fibrosis. Our study supports the antifibrotic role of Piezo1-mediated mechanical sensation in liver fibrosis, suggesting that targeting PIEZO1 to enhance macrophage efferocytosis could induce fibrosis regression."

Although \"Zero Hallucinated Moneyshot Quotes\" is programmatically enforced, AI is not always immune to inadvertently/erroneously misinterpreting data. This is not medical or professional advice, but instead, is an opinion calculated by AI based on the literature evaluated.\n\n###[CLAIM EVALUATED AND ANSWER TO USER]\nThe claim that pharmacological activation of Piezo1 ion channels overrides metabolic constraints on efferocytosis via rapid, non-transcriptional actin reorganization is not fully supported by the provided literature. While Piezo1 activation enhances efferocytosis in pro-inflammatory macrophages, the literature identifies this as a metabolically-linked pathway (involving glycolysis and HIF1\u03b1) rather than a simple override of metabolic constraints via non-transcriptional actin remodeling.\n\n### [ABSTRACT & REWRITTEN CLAIM]\nPiezo1 is a mechanosensitive ion channel involved in regulating macrophage function, particularly efferocytosis. Research suggests that while Piezo1-mediated calcium influx is central to this process, its activity is integrated with metabolic pathways (e.g., HIF1\u03b1-mediated glycolysis). There is currently insufficient evidence to conclude that Piezo1 can \"override\" metabolic depletion solely through rapid, non-transcriptional actin remodeling; rather, evidence supports that Piezo1 activity depends on energy-intensive pathways.\n\n### [INTRODUCTION & JUSTIFICATION]\nMacrophages depend on sophisticated cytoskeletal remodeling to facilitate the engulfment of apoptotic targets. The process requires highly coordinated actin dynamics, as \"Phagocytosis requires coordinated remodeling of the actin cytoskeleton to generate protrusive and contractile forces that drive target engulfment.\" Piezo1 acts as a professional mechanosensor that converts environmental signals into physiological functions, noting that \"PIEZO1 emerges as a central regulator that fine-tunes immune responses by integrating signals from the cellular microenvironment, influencing inflammation, pathogen clearance, and metabolic reprogramming.\" In the context of liver fibrosis and myocardial infarction, Piezo1 has been shown to modulate efferocytosis, where \"Pharmacological activation of Piezo1 increased the efferocytosis capacity of macrophages and accelerated the resolution of inflammation and fibrosis.\" However, this process is not independent of metabolic state, as \"A2AR signaling engaged HIF1\u03b1-dependent metabolic reprogramming to increase glycolysis, thereby providing the energetic support required for efficient and sustained efferocytosis.\" The claim that Piezo1 overrides metabolic limitations remains speculative because the evidence shows metabolic pathways (like glycolysis) are recruited to support the increased energetic demand of phagocytosis, and \"Piezo1 was involved in the efficient acidification of the engulfed cargo in the phagolysosomes and affected the subsequent expression of anti-inflammation genes after efferocytosis.\"\n\n### [DISCUSSION: NOVEL & OVERLOOKED]\n* Piezo1 acts as a metabolic integrator rather than just a mechanical gate, linking ion flux to downstream transcriptional pathways like the ATF4/SLC7A11 axis.\n* Myocardial infarction creates an environment where Piezo1 is upregulated; paradoxically, this can be maladaptive in certain contexts, as \"Piezo1 activation aggravated OGD-induced macrophage ferroptosis via Ca2+ influx followed by SLC15A3 upregulation.\"\n* Actin remodeling for phagocytosis is not only dependent on Piezo1 but also involves specific molecular motor proteins and adaptors like MYO1F, which coordinate the phagocytic cup formation.\n* Macrophages face \"phagocytic appetite exhaustion\" when endomembrane pools are depleted, indicating that mechanical activation (like Piezo1) cannot substitute for fundamental cellular resource availability.\n* The transition between pro-inflammatory (M1) and pro-resolving (M2) phenotypes is heavily influenced by metabolic reprogramming (e.g., glycolysis vs. OXPHOS) and epigenetic modifiers, which Piezo1 signaling helps regulate.\n\n### [EVIDENCE, METHODOLOGY & CITATIONS]\n1.

Klebsiella pneumoniae is an opportunistic Gram-negative pathogen that causes severe infections, particularly in susceptible individuals. This study investigated the effects of cigarette smoke extract (CSE) on K. pneumoniae virulence-associated traits and host immune responses. Three multidrug-resistant, extended-spectrum \u03b2-lactamase-producing clinical K. pneumoniae isolates were exposed to CSE. Bacterial growth, virulence gene expression (mrkA, luxS, and AcrB), biofilm formation, antimicrobial susceptibility, macrophage invasion, neutrophil phagocytosis, and cytokine responses in THP-1-derived macrophages were evaluated using microbiological, molecular, and cell culture assays. High concentrations of CSE (\u226525%) suppressed bacterial growth, whereas 5-10% CSE had minimal effects. Exposure to 10% CSE significantly upregulated mrkA, luxS, and AcrB expression. Biofilm formation increased by 20.8-37.0%, and minimum inhibitory concentrations of ciprofloxacin and tigecycline increased two-fold following CSE exposure. CSE enhanced bacterial invasion of THP-1 macrophages and impaired neutrophil phagocytosis, reducing bacterial uptake by 17.8% and 29.9% after 30 and 60 min, respectively. Furthermore, CSE promoted a pro-inflammatory response characterized by increased TNF-\u03b1 and IL-1\u03b2 expression and reduced IL-10 expression across multiple time points. CSE enhances the virulence potential of K. pneumoniae while disrupting innate immune defenses and immune regulation. These findings demonstrate a harmful synergy between cigarette smoke and bacterial infection that may contribute to the increased susceptibility and severity of respiratory infections observed in smokers.\n\nID: 42562416\nTitle: Disruption of the CD47-SIRP\u03b1 Axis Causes Profound Reduction of Parasitaemia in Mice Infected With Babesia microti.\nAbstract: Human babesiosis is an emerging disease in North America caused by the red blood cell (RBC)-infecting parasite Babesia microti. Despite a rise in clinical cases in recent years, the pathogenesis and host immune response to B. microti infection remain unclear. CD47 is a 'marker of self' transmembrane glycoprotein expressed on cell membranes that inhibits phagocytosis through interactions with macrophage signal-regulatory protein alpha (SIRP\u03b1). We posit that disruption of CD47-SIRP\u03b1 signalling will induce macrophage uptake of Babesia-infected RBCs and reduce parasitaemia in susceptible hosts. To evaluate this, we compared the in\u00a0vivo clearance of B. microti in CD47 knockout (CD47-/-) mice and wild-type C57BL/6J mice. Our results showed pronounced differences in infection kinetics between the two mouse strains. C57BL/6J mice showed steadily increasing parasitaemia that peaked at an average of 12%, whereas CD47-/- mice exhibited parasitaemia that never exceeded 1.5% throughout infection. Parasitaemia became undetectable by Day 21 in C57BL/6J and by Day 16 in CD47-/- mice, indicating resolution of infection. These results imply that, in the absence of CD47, growth of B. microti is diminished due to more efficient phagocytosis of infected RBCs by macrophages. We propose that CD47-SIRP\u03b1 signalling plays a key role in the innate response to Babesia and suggest CD47 modulation as a new therapeutic target for the treatment of babesiosis.\n\nID: 42562058\nTitle: PoGPx-7, a glutathione peroxidase homolog from teleosts, exhibits bactericidal activity and activates host immune cells against bacterial infection.\nAbstract: In mammals, glutathione peroxidase 7 (GPx-7) is a member of the GPx family that exhibits peroxidase activity. Its immunological functions, especially in host defense against bacterial infection, remain unexplored in lower vertebrates. In this study, we identified a GPx-7 homolog from Paralichthys olivaceus (PoGPx-7) and investigated its roles during Vibrio alginolyticus infection. PoGPx-7 possesses a conserved GSH-Px domain and carries positive net charges. PoGPx-7 was constitutively expressed in various tissues, with significant upregulation upon bacterial challenge. Recombinant PoGPx-7 (rPoGPx-7) exhibited GPx activity and bound to V. alginolyticus via interaction with lipopolysaccharide and peptidoglycan. In addition, rPoGPx-7 could directly kill bacteria by disrupting membrane integrity, leading to severe structural damage and content leakage. The bactericidal activity was modulated by protein concentration, pH, temperature, and Zn2+. Furthermore, rPoGPx-7 bound to peripheral blood leukocytes (PBLs), reduced bacterial attachment and LDH release, and protected PBLs from cell death. It also significantly enhanced phagocytosis, respiratory burst, and acid phosphatase activity of PBLs. In vivo administration showed that rPoGPx-7 reduced bacterial loads in the tissues, and improved fish survival, whereas knockdown of PoGPx-7 increased susceptibility to infection. These findings provide the first evidence that teleosts GPx-7 functions as a dual-effector molecule with direct bactericidal activity and immunomodulatory capacity, providing an immunological insight of GPx family members on resistance bacterial infection.\n\nID: 42561943\nTitle: C9orf72-associated and sporadic FTD patient iPSC-microglia show differences in phagocytosis and gene expression.\nAbstract: C9orf72 hexanucleotide repeat expansion (C9-HRE) is a major genetic cause of amyotrophic lateral sclerosis and frontotemporal dementia (FTD). However, approximately half of the FTD patients are sporadic without a clear genetic background. To compare characteristics of microglia from different FTD subtypes, we generated induced pluripotent stem cell-derived microglia (iMG) from sporadic and C9-HRE-carrying behavioral variant FTD (bvFTD) patients and healthy controls. C9-HRE iMG displayed C9-HRE-associated RNA foci and dipeptide repeat proteins. All bvFTD iMG had fewer LAMP2-A-positive vesicles compared to control iMG. Additionally, C9-HRE iMG showed significantly increased LC3BII/I conversion after bafilomycin A1 treatment and altered phagocytic activity. The gene expression profile of C9-HRE iMG only modestly differed from the control iMG, but was greatly different from the sporadic bvFTD patient iMG. Our data show alterations in phagocytic and autophagosomal/lysosomal pathways and gene expression profiles between C9-HRE and sporadic bvFTD iMG for the first time.\n\nID: 42561801\nTitle: Macrophage polarization-inducible cholesterol lipid-assisted nanoparticles prime systemic antitumor immunity.\nAbstract: Nanomaterials with intrinsic biological activity can directly participate in disease treatment, emerging as a pivotal focus in the development of next-generation therapeutics. In this study, we synthesized a library of cholesterol lipids bearing diverse tertiary amine head groups via a straightforward amidation reaction, then co-assembled them with amphiphilic polyethylene glycol-poly (lactic-co-glycolic acid) (PEG-b-PLGA) to formulate hybrid nanomaterials. Notably, the cholesterol derivative A3-Chol-formulated nanomaterials (A3-Chol@NP) polarized macrophages toward the pro-inflammatory M1 phenotype and enhanced phagocytosis of tumor cells. At the mechanistic level, A3-Chol@NP has been observed to preferentially interact with mitochondria in macrophages to produce mitochondrial reactive oxygen species (mtROS). This, in turn, activates ROS-NF-\u03baB-iNOS and ROS-IRF5-IL-23 pathways, which have been identified as key factors in the macrophage polarization to M1-type. In the B16-F10 mouse melanoma model, A3-Chol@NP efficiently suppressed tumor growth via macrophage-mediated immunotherapy and completely blocked tumor progression when combined with anti-PD-L1 antibody.\n\nID: 42560551\nTitle: \u03b2-hydroxybutyrate regulates microglia M1/M2 polarization and phagocytosis through the JAK1/STAT1 pathway to reduce neuroinflammation and exert anti-epileptic effects.\nAbstract: Neuroinflammation and microglia M1/M2 polarization imbalance are among the core pathological mechanisms of epilepsy (EP), with the JAK1/STAT1 pathway being vital in neuroinflammation. \u03b2-hydroxybutyrate (BHB), a ketone body metabolite, has anti-inflammatory and neuroprotective potential, but whether it can ameliorate EP-related neurological damage by modulating this pathway remains unclear.\u00a0To investigate whether BHB regulates microglia polarization and phagocytosis through the JAK1/STAT1 pathway, attenuates neuroinflammation and neuronal injury, and thus exerts anti-EP effects.\u00a0A rat primary neuronal EP model and lipopolysaccharide (LPS)-induced M1-type microglia model were constructed, and microglia polarization, migration, phagocytosis, and neuronal damage were detected by scratch assay, flow cytometry, Hoechst 33,342/PI staining, Cell Counting Kit-8 assay, and ELISA kits. A rat model of Pentetrazol (PTZ)-induced EP was constructed to detect the effects of BHB on the symptoms of EP in rats by behavioral assessment, and to detect brain tissue damage by pathological staining. Western blot was conducted to detect microglia polarization markers, neuronal apoptosis, synapse-related proteins, and JAK1/STAT1 pathway-related proteins expression. Pathway specificity was verified using JAK1 overexpression plasmid (OE-JAK1) and STAT1 inhibitor (Fludarabine).\u00a0BHB concentration-dependently increased EP neuron viability and suppressed M1 polarization induced by LPS, and promoted M2 polarization. BHB also enhanced the migration and phagocytosis of microglia, and reduced pro-inflammatory factor release, which in turn attenuated their pro-inflammatory damage to neurons and protected synaptic integrity, and this effect was linked to its suppression of JAK1/STAT1 pathway activation. Additionally, BHB extended seizure latency, decreased seizure duration, and reduced seizure severity in EP rats, and effectively attenuated brain histopathological damage and promoted neuronal regeneration and axonal repair. Furthermore, BHB was also effective in promoting microglia M2 polarization and enhancing their phagocytosis in vivo. Overexpression of JAK1 attenuated the neuroprotective effects of BHB, and Fludarabine attenuated the impacts of overexpression of JAK1.\u00a0By inhibiting the JAK1/STAT1 pathway, BHB promotes microglia M2 polarization and enhances their phagocytosis, attenuates neuroinflammation and neuronal injury, and ultimately exerts anti-EP effects.\n\nID: 42559470\nTitle: Endothelial epigenetic senescence driven microglial activation mediates cardio-retinal neuroinflammation in heart failure.\nAbstract: Heart failure (HF) is increasingly recognized as a systemic disorder that extends beyond the heart and affects neurovascular tissues, including the retina. However, the mechanisms by which circulating factors from HF trigger retinal neuroinflammation remain unclear. HF was induced in adult mice by transverse aortic constriction (TAC). Retinal structure and function were evaluated using optical coherence tomography (OCT) and electroretinography (ERG). Parabiosis and plasma transfer experiments were performed to assess the role of circulating factors. Endothelial senescence, microglial activation, and inflammatory signaling were analyzed using immunofluorescence, qPCR, and molecular assays. The functional relevance of TGF\u03b22 and microglia was tested using anti-TGF\u03b22 antibody administration and microglial depletion with PLX5622 treatment. TAC mice exhibited pronounced retinal thinning, diminished electroretinography (ERG) amplitudes, and reduced vascular density. Exposure of healthy mice to HF plasma reproduced these abnormalities, indicating that circulating mediators drive retinal injuries. TGF\u03b22 levels were markedly elevated in the plasma of both patients with HF and TAC mice. Mechanistically, TGF\u03b22 activated the pSMAD2/EP300 pathway in retinal endothelial cells, promoting H3K9 acetylation, P21 induction, and endothelial cell senescence. Senescent endothelial cells release proinflammatory factors that activate retinal microglia, leading to hypertrophic morphology, enhanced synaptic phagocytosis, and upregulation of cytokines such as IL1\u03b2, TNF\u03b1, and IL6. Neutralization of TGF\u03b22 or microglial depletion markedly reduced inflammation, preserved the retinal architecture, and restored visual function. Elevated TGF\u03b22 levels in heart failure drive retinal endothelial epigenetic senescence, which secondarily activates microglia and induces neuroinflammation. Endothelial-specific disruption of TGF\u03b22 signaling is sufficient to protect the retina independently of primary cardiac recovery. Targeting the TGF\u03b22-endothelial-microglia axis may represent a promising therapeutic strategy for preventing retinal neurovascular degeneration associated with systemic cardiac disease.\n\nID: 42558706\nTitle: Maternal Stress Primes Adolescent Stress Susceptibility via Microglial Complement-Dependent Synaptic Phagocytosis.\nAbstract: Early-life adversity, including prenatal stress exposure, has enduring effects on stress responsivity later in life. Yet the impact of maternal stress on offspring susceptibility to stress and its underlying biological mechanisms remain to be elucidated. Here, we established a \"2-hit\" stress model to investigate whether maternal chronic unpredictable stress (E9.5 to E18) increases offspring susceptibility to social isolation during adolescence (P28 to P49). Our study reveals that maternal stress increases susceptibility to adolescent social isolation in male-but not female-offspring, manifested as increased anxiety- and depressive-like behaviors. This vulnerability is mediated by the priming of hippocampal dentate gyrus microglia through the complement C3-C3aR signaling pathway, which promotes the aberrant phagocytosis of excitatory synapses and reduces glutamatergic neuronal activity. Notably, pharmacological blockade of C3aR or chemogenetic activation of glutamatergic neurons in the dentate gyrus during adolescence effectively alleviated stress susceptibility. Therefore, our findings identify a targetable immune-mediated mechanism in the hippocampus that underlies stress vulnerability in offspring exposed to gestational maternal stress, offering new avenues for preventing adolescent-onset mood disorders.\n\nID: 42558661\nTitle: Cutaneous Intravascular Large B-Cell Lymphoma Presenting as Hemophagocytic Lymphohistiocytosis.\nAbstract: Intravascular large B-cell lymphoma (IVLBCL) is an uncommon and aggressive subtype of non-Hodgkin lymphoma defined by the proliferation of large malignant B cells confined within small blood vessels. This neoplasm can present with different nonspecific symptoms, including fever, altered mental status, livedoid skin rashes, hepatosplenomegaly, and cytopenias, often complicating its diagnosis. The main categories are classical (formerly designated as Western), hemophagocytic variant (formerly designated as Asian), and primary cutaneous IVLBCL. A distinctly severe manifestation is hemophagocytic lymphohistiocytosis (HLH), a hyperinflammatory syndrome characterized by exaggerated immune activation and macrophage activation manifested by phagocytosis of hematopoietic cells including neutrophils, red blood cells, and platelets. We describe a 72-year-old female who presented with features reminiscent of an autoinflammatory syndrome including fever and hyperferritinemia followed by clinical features concerning for HLH. She developed a reticulated skin rash. Following skin biopsy, a diagnosis was rendered of IVLBCL complicated by HLH. The pathophysiology and other aspects of the literature pertaining to IVLBCL and HLH are reviewed.\n\nID: 42558291\nTitle: IL-33 promotes efferocytosis by peritoneal macrophages by a mechanism associated with rapid granulocyte IL-13 production.\nAbstract: Resolution of inflammation is an active process that requires efferocytosis, the engulfment of apoptotic cells by macrophages, mediated by receptors such as MerTK. IL-33 is an alarmin that initiates type 2 immune responses, including increased production of IL-13, which promotes MerTK expression. The ability of IL-33 to promote efferocytosis in vivo was examined. Intraperitoneal administration of IL-33 to mice increased local MerTK+ macrophage numbers within 48h. MerTK+ macrophages were not similarly induced by free mitochondria, an alternative cell damage associated signal. Efferocytotic activity was increased rapidly in response to apoptotic thymocytes in IL-33-treated mice. The established inducer of MerTK expression, IL-13, was detected in peritoneal lavage fluid shortly after IL-33 administration. Peritoneal eosinophils expressed the IL-33 receptor and demonstrated both intracellular IL-13 by flow cytometry and significantly increased Il13 transcript expression following IL-33 treatment. In contrast, neither elevated IL-13 expression nor IL-13 protein secretion was observed in peritoneal lymphocyte populations within the first 6 hours after IL-33 administration. Primary cultures of bone marrow-derived mouse mast cells and eosinophils demonstrated IL-13 protein responses to IL-33 administration within 6\u00a0h. Mast cell-deficient Cpa3-Cre; Mcl-1fl/fl mice had significantly reduced IL-13 levels in the peritoneal cavity 3 hours after IL-33 administration when compared with mast cell-containing littermates. In contrast, IL-33-treated eosinophil-deficient \u0394dblGATA mice had similar levels of IL-13 at this time point as wild type controls. These data demonstrate that IL-33 promotes MerTK expression, critical for efferocytosis by macrophages, by a process associated with an early rapid local increase in IL-13 production to which mast cells are a substantial early contributor. These findings contribute to our understanding of clinical situations where elevated soluble IL-33 receptor (sST2) and/or lower mast cell numbers are associated with worse clinical outcome.\n\nID: 42558045\nTitle: Gas-6 Scavenges Anionic Phospholipid-Expressing Microparticles and Mitigates TBI-Induced Endotheliopathy and Coagulopathy in Mice.\nAbstract: Traumatic brain injury (TBI) results in the release of microparticles from injured brain cells into circulation. These microparticles induce a systemic hypercoagulable state that rapidly transitions into secondary coagulopathy and endotheliopathy. We hypothesize that removing these microparticles from circulation could mitigate the TBI-induced secondary pathologies and improve outcomes. In this study, we investigated the role of Gas-6 (growth arrest-specific 6) as a scavenging factor for microparticles. We quantified plasma Gas-6 levels in a mouse model of TBI and administered exogenous Gas-6 either before or after TBI to evaluate its effects on endotheliopathy, coagulopathy, and outcomes. Mechanistic studies assessed Gas-6-mediated clearance of circulating microparticles in TBI mice and investigated the molecular interactions by which Gas-6 binds microparticles and macrophages to facilitate microparticle scavenging. We found that plasma levels of Gas-6 were significantly reduced in mice subjected to severe TBI. Exogenous Gas-6 given either preinjury or postinjury attenuated coagulopathy, protected the integrity of the cerebral and pulmonary endothelium, improved neurological recovery, and increased overall survival of TBI mice. Gas-6 increased the clearance of anionic phospholipid-expressing microparticles from circulation by coupling microparticles with macrophages and monocytes through the \u03b3-carboxyglutamate and the LG1 (laminin G-like domain 1), respectively, to facilitate phagocytosis of microparticles in the liver. These findings demonstrate the therapeutic potential of Gas-6 for TBI and potentially for other acute pathologies, in which microparticles initiate and propagate coagulation dysfunction and endothelial injuries.\n\nID: 42557884\nTitle: The P2X7 Receptor in Cancer: From Functional Receptor to Non-Functional P2X7.\nAbstract: The ATP-gated P2X7 receptors are abundantly expressed in immune cells, neurons, glial cells, and cancer cells. The P2X7 receptor performs distinct functions, depending on the extracellular ATP concentration and the duration of exposure to ATP. With brief ATP stimulation, the P2X7 receptor acts as an ion channel, and the movement of ions is associated with the regulation of cell proliferation and differentiation. Prolonged ATP exposure induces a conformational change in P2X7, allowing large molecules to pass through the membrane via the formation of macropores, thereby contributing to cell death. A novel function of P2X7 as a scavenger receptor was recently reported in the absence of both serum and ATP. However, the discovery of non-functional P2X7 in cancer reveals that this group of isoforms of P2X7 fails to form macropores upon ATP stimulation and cannot initiate ATP-induced cell death, allowing malignant cells to evade this regulatory mechanism and continue proliferating. We discuss the multifaceted functions of the P2X7 receptor in regulating diverse cell types, including cell growth, death, and clearance, and how the non-functional form of P2X7 disrupts this balance in cancer. Furthermore, the review explores the potential targeting of this aberrant isoform of P2X7 in the development of novel cancer therapies.\n\nID: 42557441\nTitle: Damage recognition by intestinal stem cells via Draper promotes adult Drosophila midgut regeneration.\nAbstract: Tissue regeneration after injury is crucial for restoring epithelial structure and function. Upon damage, a regenerative microenvironment forms that provides signalling cues that stimulate stem cell proliferation to replace lost cells. While this process is well understood, how stem cells themselves sense damage, translate this input into their proliferation and shape\u00a0the regenerative microenvironment remains unclear. Here we show that Draper-Src-Shark signalling in Drosophila intestinal stem cells (ISCs) recognises tissue damage by sensing externalised phosphatidylserine on dying midgut epithelial cells and is required for STAT activation in ISCs to promote their proliferation. Unlike its role in phagocytosis, Draper in ISCs does not promote the clearance of these apoptotic enterocytes but rather facilitates ISC proliferation in the presence of damaged enterocytes. Moreover, Draper-Src-Shark signalling in progenitors regulates STAT transcriptional activity in the adjacent visceral muscle, indicating that progenitors can shape the regenerative microenvironment beyond tissue boundaries. As Src and STAT are also activated in the mammalian intestinal epithelium after damage and tumour formation, these findings may help develop therapies for tissue regeneration, inflammatory diseases and cancer.\n\nID: 42556549\nTitle: LitCTL1: A novel C-type lectin involved in the mucosal and cellular immunity of the common periwinkle Littorinalittorea.\nAbstract: C-type lectins (CTLs) are vital pattern-recognition receptors (PRRs) that mediate innate immune responses in mollusks, yet their characterization in Caenogastropoda, the largest gastropod group, remains limited. This study characterizes LitCTL1, a novel secreted single-domain C-type lectin from the common periwinkle, Littorina littorea. The 199-amino acid polypeptide contains a conserved carbohydrate recognition domain with canonical QPD and WND motifs and is predicted to form a homodimer. Uniquely, LitCTL1 was localized in both circulating hemocytes and mucus-secreting epithelial cells of the foot, mantle, and hypobranchial gland - the first report of such dual localization for a molluscan lectin, linking systemic and mucosal defense. Expression analysis revealed that LitCTL1 is constitutively expressed in hemocytes. Functional assays with recombinant LitCTL1 demonstrated its role as a potent opsonin with hemagglutinating activity, significantly enhancing hemocyte spreading and the phagocytosis of zymosan. Genomic analysis reveals that LitCTL1 belongs to a rapidly diversifying, genus-specific expansion distinct from conserved perlucin-like lineages. These results identify LitCTL1 as a key effector molecule in both systemic and mucosal innate immunity, likely reflecting an evolutionary adaptation to the microbial challenges of the intertidal environment.\n\nID: 42556114\nTitle: Mechanistic insights into the immunomodulatory and antibacterial activity of the Japanese Kampo Formula Hainosankyuto.\nAbstract: This study aimed to quantify the in vitro antibacterial activity of the Japanese herbal formula Hainosankyuto (HNST) against Gram-positive and Gram-negative bacteria and to elucidate its immunomodulatory effects on human monocytes. The antibacterial activity of HNST was assessed against Escherichia (E.) coli DH5\u03b1 and Streptococcus (S.) pneumoniae D39 using bacterial growth curve analysis. The immunomodulatory effects were examined in THP-1 monocytes by quantifying phagocytosis via a gentamicin protection assay, cytokine release by enzyme immunoassay and NF-\u03baB activation using the THP1-Blue\u2122 NF-\u03baB reporter cell line. Cell viability was evaluated by microscopy and lactate dehydrogenase (LDH) release assays. The potential for lipopolysaccharide (LPS) contamination was assessed using a Limulus amoebocyte lysate (LAL) assay and validated with the TLR4-deficient THP1-Dual\u2122 KO-TLR4 reporter cell line. HNST exhibited significant antibacterial activity against the Gram-positive strain S. pneumoniae, but not against E. coli. It enhanced phagocytic activity and induced NF-\u03baB activation in THP-1 monocytes in a concentration-dependent manner. Compared to an unstimulated control, HNST moderately increased intracellular killing of bacteria. These effects were independent of its LPS content. No significant cytokine release was detected at non-cytotoxic concentrations. Cytotoxicity was observed at higher concentrations. HNST demonstrated immunomodulatory and selective antibacterial activity, which supports its traditional use as an immune-enhancing agent. However, these preliminary findings require further pharmacological and in vivo validation. The data highlight the potential of HNST as a possible complementary therapeutic approach in the era of increasing antibiotic resistance. Further studies are necessary to elucidate its active components and mechanisms of action.\n\nID: 42555848\nTitle: Assessing Vancomycin-Formyl Peptide Conjugate Binding to the Surface of Resistant Staphylococcus aureus via Flow Cytometry.\nAbstract: Staphylococcus aureus strains have emerged with resistance mechanisms that reduce the efficacy of last resort antibiotics and evade the immune system. One strategy to combat antimicrobial resistance is to modulate host immunity to eliminate infections more effectively. This has led to the development of immunotherapeutics consisting of vancomycin conjugated to formyl peptides (fPeps), with vancomycin targeting the cell wall and the fPeps engaging host innate immunity. Here, we used flow cytometry to quantify the binding of vancomycin=fPep conjugates to S. aureus clinical isolates. This revealed reduced binding of vancomycin=fPeps compared to vancomycin alone and quantified the interaction between the conjugates and the bacterial cell surface, which is important to quantify to then control the chemotactic gradient established by the fPep cargo. The direct antimicrobial activity of these conjugates was also reduced when compared to vancomycin, reflecting the reduced binding of these conjugates to S. aureus. This flow cytometry method allows quantification of vancomycin=fPep binding to bacteria and will assist in future studies to understand how attached fPeps and other immune signalling cargoes can stimulate innate immune cell activation leading to bacterial phagocytosis.\n\nID: 42555090\nTitle: TREM2 Deficiency Attenuates Endometriosis Progression by Inhibiting M2 Polarization of SpMs and Suppressing SIRP\u03b1 to Enhance Phagocytosis.\nAbstract: Endometriosis (EMS) is characterised by a disrupted peritoneal immune microenvironment where M2 macrophage polarization and impaired phagocytosis promote lesion survival. Single-cell RNA-seq (ScRNAseq) of the peritoneal macrophages from EMS patient revealed elevated Triggering Receptor Expressed on Myeloid cells 2 (TREM2) and signal regulatory protein \u03b1 (SIRP\u03b1). The expression of TREM2 and SIRPa is positively correlated, and each are positively correlated with estrogen response. Mouse EMS model was established by intraperitoneal injection of estrogen primed mouse endometrial fragments into recipient female mice. In vitro estrogen treatment of RAW 264.7 cells indicated an increasing TREM2/SIRP\u03b1 expression and enhancing phagocytosis of lesion cells derived from WT EMS ectopic lesions. Peritoneal macrophage from mice with EMS were analyzed using flow cytometry for the expression of TREM2 and SIRP\u03b1. The assessment of F4/80, CD206, and SIRP\u03b1 expressing cells within the lesions were performed through the implementation of multi-color immunohistochemistry (mIHC). Small peritoneal macrophages (SpMs, F4/80low CD11blow) were markedly increased in the EMS model. Trem2 knockout mice, as the recipient, showed smaller ectopic lesion size and less lesion formation. TREM2 deficiency inhibited SpM polarization into M2 and downregulated their SIRP\u03b1 expression, while enhancing phagocytic activity. Mechanistically, estrogen pretreatment upregulated TREM2, which correlated with SIRP\u03b1 upregulation and impaired phagocytosis. Under estrogen exposure, TREM2 knockdown RAW 264.7 cells potentiated phagocytosis. Thus, TREM2 is an important contributing pathogenic factor in promoting EMS by enhancing M2 polarization and suppressing phagocytosis via SIRP\u03b1 upregulation.\n\nID: 42554945\nTitle: GPR146 Deficiency Enhances Microglial Phagocytosis and Blood-Brain Barrier-Associated Markers in an Acute Amyloid-\u03b2 Model.\nAbstract: Dysregulation of brain cholesterol homeostasis is increasingly recognized as a critical driver of Alzheimer's disease (AD) pathogenesis. G protein-coupled receptor 146 (GPR146) has emerged as a pivotal regulator of systemic cholesterol metabolism; however, its role in the central nervous system and AD remains elusive. Here, we report that GPR146 deficiency in mice modulates ERK/PKA signaling without affecting baseline physiology or general behavior. Following intracerebroventricular (i.c.v.) injection of amyloid-\u03b2 (A\u03b2)42 oligomers, GPR146 was associated with altered A\u03b242-evoked ERK/PKA/Akt signaling both in vivo and in vitro. Mechanistically, Gpr146 ablation potentiated microglial A\u03b2 phagocytosis, which correlated with the transcriptional upregulation of phagocytic receptors, including TREM2, GPR34, P2Y6, and CR3, alongside increased expression of pro-inflammatory cytokines (TNF-\u03b1, IL-1\u03b2, IL-6). Moreover, GPR146 deficiency was linked to elevated levels of blood-brain barrier (BBB)-associated markers Cldn-5 and Glut-1 protein levels, while attenuating A\u03b2\u2011induced inflammatory responses in brain endothelial cells. At the metabolic level, GPR146 knockout modulated the expression of key enzymes governing glucose (GLUT1, GLUT3, G6PD, PFK, HK) and lipid (HMGCS1, ACACA, FASN, SCD1) metabolism and markedly reduced A\u03b2\u2011elicited lipid droplet accumulation in the cortex and hippocampus. Collectively, our findings establish GPR146 as a novel neurometabolic regulator whose deficiency correlates with enhanced A\u03b2 phagocytosis, maintenance of BBB-associated proteins, and altered cerebral metabolism, thereby presenting a potential therapeutic axis for early AD intervention.\n\nID: 42554595\nTitle: Redirecting Monocyte Differentiation With Engineered Extracellular Vesicles for Glioma Immunotherapy.\nAbstract: During glioma progression, monocytes abundantly infiltrate but primarily differentiate into immunosuppressive macrophages to promote tumor growth. Redirecting monocyte differentiation offers a compelling yet underexplored therapeutic opportunity. In this work, we found M1-polarized macrophage-derived extracellular vesicles (M1-EVs) efficiently induced monocytes to differentiate into anti-tumor macrophages via tumor necrosis factor alpha (TNF-\u03b1)-mediated signaling. Despite promising, the therapeutic efficacy of M1-EVs was constrained by insufficient glioma accumulation and CD47-mediated phagocytic inhibition. To address this challenge, we further engineered M1-EVs with dual-targeting specificity by genetically incorporating a tumor-directed chimeric antigen receptor (CAR) against IL13R\u03b12 or EGFRvIII together with CD47-blocking SIRP\u03b1 variants. The resulting dual-targeting EVs (M1-CS-EVs) exhibited enhanced blood-brain barrier (BBB) penetration and glioma accumulation while locally disrupting CD47-SIRP\u03b1 interactions. In three orthotopic glioma models, M1-CS-EVs elicited a potent anti-tumor immune response and enhanced tumor phagocytosis, significantly suppressing tumor growth while prolonging animal survival. Our findings establish a platform technology for directing monocyte differentiation toward anti-tumor phenotypes, offering a broadly applicable strategy for glioma treatment.\n\nID: 42554417\nTitle: Functional and Structural Characterization of a Large Animal Model of RDH5-Associated Retinopathy.\nAbstract: Inherited retinal diseases are a group of hereditary diseases that cause variable levels of blindness and affect a multitude of adults and children. One such disease is fundus albipunctatus (FA). FA is caused by autosomal recessive retinol dehydrogenase 5 (RDH5) mutations and results in rod dysfunction leading to night blindness and, in a subset of patients, macular degeneration (MD). We previously reported a spontaneous feline model of FA due to an RDH5 missense mutation. The affected cats showed rod dysfunction and a proportion developed degeneration of the area centralis (AC), equivalent to MD in humans. We used fundus confocal scanning laser ophthalmoscopy and spectral-domain optical coherence tomography imaging, six different electroretinography protocols, immunohistochemistry, and histology/transmission electron microscopy to further characterize this large-animal cat model. In addition to rod dysfunction, cone recovery from intense stimulation was impaired. For RDH5-/- cats that developed AC degeneration, an initial elongation of rod outer segments with disorganization of the distal tips was initially detected in the AC and visual streak, suggestive of impaired shedding/phagocytosis. With progression, photoreceptors degenerated in the AC, matching the MD seen in some human patients. The RDH5-/- cat model recapitulates features of both rod and cone dysfunction seen in human patients with RDH5 mutations. The RDH5-/- cat model offers a unique opportunity to further understand the mechanisms of RDH5-associated retinopathies and to investigate potential therapeutic approaches.\n\nID: 42553038\nTitle: Nutrient deprivation increases CD3 expression in RAW cells and augments the CD3-induced proinflammatory profile, associated with NFAT and IRF-1.\nAbstract: Myeloid cells can express lymphoid markers, including components of the CD3-TCR complex. CD3+ macrophages have been identified in both infectious and non-infectious pathologies; however, their origin and signaling mechanisms remain poorly studied, primarily due to their low prevalence in human samples. Utilizing the RAW murine macrophage cell line as a model, this study aimed to ascertain whether nutrient deprivation induces CD3 expression and to identify the signaling molecules involved in the activation of a CD3-dependent proinflammatory profile. Firstly, the impact of environmental stress, specifically nutrient deprivation, on CD3 expression over a period was assessed. Subsequently, RAW cells were stimulated with anti-CD3 and IgG2a, and the profile of proinflammatory cytokines was evaluated alongside the expression of signaling proteins, including NFAT, c-Jun, and IKK. Furthermore, the transcriptional regulation of IRF-1, GATA-3, and MAFB was examined. Lastly, the functional capacity of CD3+ RAW cells was determined through a phagocytosis assay. RAW cells were found to express molecules classically associated with T cells, including CD3, TCR, and CD4. Notably, CD3 expression was significantly upregulated at both the protein and transcriptional levels under nutrient deprivation, although it did not reach the levels observed in T cells. Functionally, CD3+ RAW cells exhibited enhanced phagocytic activity toward latex beads. Furthermore, stimulation with anti-CD3 plus IgG2a induced a robust proinflammatory cytokine response, characterized by the secretion of IFN-\u03b3, TNF, and IL-6 as early as 5 hours post-stimulation. This response was associated with activation of signaling pathways involving NFAT, c-Jun, and IKK, along with increased IRF-1 expression and downregulation of MAFB, supporting the establishment of a CD3-dependent proinflammatory profile in RAW cells. Our findings establish RAW macrophages as a model to study CD3+ signaling machinery in myeloid cells. We demonstrate for the first time that nutrient deprivation induces CD3 expression and that the resulting CD3-driven proinflammatory program is associated, at least in part, with NFAT and IRF-1. These conclusions provide new insights into the origin and functional significance of CD3+ macrophages and offer a valuable platform for investigating the impact of this pathway on innate immune responses across various pathological contexts.\n\nID: 42552556\nTitle: Galectin-3 is elevated in M\u00fcller glia in human glaucomatous eyes and ocular hypertensive rat eyes and associated with phagocytosing states.\nAbstract: Glaucoma is a leading cause of irreversible blindness worldwide, yet available treatments fail to prevent disease progression for all patients. It is characterized by a progressive dysfunction and loss of retinal ganglion cells. Neuroinflammation has been recognized as an underlying neurodegenerative mechanism of glaucoma in animal models and human post-mortem samples, and targeting neuroinflammation may provide additional means to neuroprotection. Galectin-3, a pro-inflammatory mediator encoded by the LGALS3 gene in humans, holds promise as a treatable target as its pharmacological and genetic inhibition is neuroprotective in multiple models of experimental glaucoma. However, the role of Galectin-3 in glaucoma remains unclear, particularly whether its emergence is a consequence of degeneration, or occurs at earlier time points. To address these knowledge gaps, we labeled IBA1, GFAP, and Galectin-3 in retina sections at early glaucoma stages in the rat bead glaucoma model, and in human retina from glaucoma donors. In the rat, IBA1 volume, but not GFAP, increased at an early, pre-degenerative timepoint. Accompanying this, we identified a significant increase of Galectin-3/IBA1 colocalization compared to control at the same timepoint, supporting the upregulation of Galectin-3 in early inflammation, preceding retinal ganglion cell degeneration in experimental glaucoma. However, a significant increase in Galectin-3/GFAP colocalization compared to control at the same timepoint in the rat additionally associates Galectin-3 production with astrocytes and M\u00fcller glia. This Galectin-3 to M\u00fcller glia relationship was significantly pronounced in human glaucomatous retina, predominating over microglia co-labelling. We further demonstarted that human MIO-M1 M\u00fcller glia in vitro express Galectin-3, but this is not altered in response to glaucoma relevant stimuli (TNF-\u03b1 or mild-metabolic stress from rotenone). Instead, Galectin-3 expression was altered in phagocytosing states from exposure to E. coli particles, brain synaptosomes, or apoptotic neuronal debris. These findings provide further insight into Galectin-3 and gross inflammatory responses in glaucoma pathology.\n\nID: 42552059\nTitle: \u03b2-glucan elicits APOE-dependent peripheral trained immunity to suppress hepatocellular carcinoma.\nAbstract: Although immunotherapy has revolutionized cancer treatment, hepatocellular carcinoma (HCC) continues to demonstrate limited clinical responses, highlighting the urgent need for novel immunomodulatory strategies. Trained immunity, an emerging paradigm wherein innate immune cells develop a memory-like phenotype through epigenetic and metabolic reprogramming, offers a promising avenue to remodel the immunosuppressive tumor microenvironment. This study investigated whether \u03b2-glucan-induced trained immunity could potentiate antitumor immunity against HCC. We established orthotopic HCC mouse models to investigate the role of trained immunity induced by whole \u03b2-glucan particle (WGP) in the HCC microenvironment, particularly in modulating hepatic apolipoprotein E (APOE)-positive monocytes/macrophages. Transcriptional changes in trained monocytes/macrophages were identified by analyzing single-cell RNA sequencing and bulk RNA-sequencing data from the livers of WGP-treated and control mice. Mechanistic studies were performed using Apoe -/- mice and in situ monocyte/macrophage engineering. Flow cytometry was performed to assess immune cell phenotypes and phagocytosis, while luminescence-based assays were used to evaluate cytotoxic activity. The translational potential was assessed using human monocyte training assays. This study demonstrated that preconditioning with WGP, a trained immunity inducer, increased the accumulation of trained monocytes/macrophages in the liver and suppressed tumor progression in HCC mouse models. Mechanistically, WGP-trained APOE+ monocytes/macrophages exhibited a decrease in lipid accumulation and endoplasmic reticulum stress, thereby enhancing their antitumor function. Genetic deletion of Apoe in monocytes/macrophages abrogated the antitumor effects of WGP, demonstrating that APOE+ monocytes/macrophages are essential mediators of WGP-induced trained immunity. Adoptive transfer of WGP-trained bone marrow-derived macrophages suppressed the growth of HCC in recipient mice. Furthermore, WGP induced trained immunity in human monocytes, leading to enhanced killing of HCC cells. Notably, combination therapy with WGP and anti-programmed death-ligand 1 antibody achieved superior tumor control compared with either monotherapy. These findings identify a critical role for trained APOE+ monocytes/macrophages in WGP-mediated antitumor immunity in the liver. Harnessing WGP-induced peripheral trained immunity represents a novel therapeutic strategy for HCC.\n\nID: 42551598\nTitle: Mechanistic insight into Solanum lyratum extract for ameliorating imiquimod-induced psoriasis in mice via suppression of mast cells and Th17 cell response.\nAbstract: To investigate the underlying mechanism of Solanum lyratum Thunb. (SLT) against psoriasis. A mouse model of psoriasis was established by topical application of imiquimod (IMQ) cream on the nape and dorsal skin. Mice were randomly allocated into the blank control group, model group, SLT treatment groups (low-, medium- and high-dose), and positive control group, with 6 mice in each group. The administration lasted for 7 consecutive days. The skin lesions and pruritic behaviors of mice were observed. Hematoxylin-eosin (H&E) staining was performed to assess the pathological changes of lesional skin and spleen tissues. Toluidine blue staining was used to detect the alterations of mast cells. Immunofluorescence staining was applied to evaluate the changes of T helper 17 (Th17) cells and neutrophils in lesional skin and spleen tissues. Untargeted metabolomics profiling via ultra-performance liquid chromatography coupled with quadrupole time-of-flight mass spectrometry (UPLC-Q-TOF-MS) was conducted to identify differential metabolites in mouse serum, screen potential biomarkers, and analyze the involved metabolic pathways combined with the Kyoto Encyclopedia of Genes and Genomes (KEGG) database. Enzyme-linked immunosorbent assay (ELISA) was used to determine the content changes of interleukin (IL)-17\u202fA, IL-23, tumor necrosis factor-\u03b1 (TNF-\u03b1), IL-1\u03b2, IL-4, interferon-\u03b3 (IFN-\u03b3), vascular endothelial growth factor (VEGF), histamine (HIS), and 5-hydroxytryptamine (5-HT) in lesional skin tissues. SLT alleviated IMQ-induced psoriasis-like skin lesions and spleen edema in mice. SLT ameliorated epidermal hyperplasia and mast cell infiltration in psoriatic lesional skin, and improved inflammatory cell infiltration in both lesional skin and spleen tissues of psoriatic mice. Meanwhile, SLT regulated the levels of Th17 cells and neutrophils in the above two tissues. A total of 30 differential metabolites were screened out via serum metabolomics analysis, which were mainly enriched in signaling pathways including glycerophospholipid metabolism, fatty acid biosynthesis, biosynthesis of unsaturated fatty acids, dysregulated fatty acid metabolism, and Fc\u03b3 receptor-mediated phagocytosis. In addition, SLT significantly downregulated the contents of IL-17\u202fA, IL-23, IL-1\u03b2, HIS and 5-HT in psoriatic lesional skin. SLT exerts a dual anti-psoriatic effect of anti-inflammation and anti-pruritus by inhibiting immune cells such as Th17 cells and mast cells, thereby downregulating inflammatory factors associated with the Th17/IL-23 axis and pruritogens released by activated mast cells. Furthermore, untargeted metabolomics analysis revealed that the anti-psoriatic mechanism of SLT may be closely related to lipid metabolism disorder, a hallmark pathological feature of psoriasis.\n\nID: 42284316\nTitle: Molecular characterization of superficial zone chondrocytes under pro-inflammatory and biomechanical stress conditions.\nAbstract: Osteoarthritis (OA) is a chronic degenerative joint disease characterized by pathological features such as chondrocyte loss and cartilage matrix degradation. Superficial zone chondrocytes (SFC), located in the outermost layer of articular cartilage and in direct contact with synovial fluid, are the first to respond to mechanical stress and friction. In this study, SFC were isolated and identified in vitro, and their\u00a0proliferatives\u00a0and anti-apoptotic properties were examined. Additionally, an early OA inflammatory environment was successfully simulated in cell experiments, demonstrating that inflammatory conditions reduce stemness-associated marker expression in SFC, activate multiple inflammatory pathways, and promote MMP3 expression. When SFC were subjected to cyclic mechanical stretching under inflammatory conditions, increased expression of the mechanosensitive channel Piezo1, enhanced calcium-associated mechanotransduction sensitivity, and disruption of the cytoskeleton were associated with aggravated catabolic responses and apoptosis under inflammatory mechanical stimulation. These findings elucidate the role of SFC in early OA pathogenesis and provide insight into early OA pathogenesis and suggest potential directions for mechanism-based intervention.\n\nID: 42223634\nTitle: PIEZO1 in Immune Cells: From Force to Function.\nAbstract: As a professional mechanosensor, PIEZO1 converts mechanical stimuli-such as substrate stiffness, fluid shear stress, and membrane tension-into intracellular calcium influx, which in turn regulates a wide array of immune processes. The chapter details its significance across both innate and adaptive immunity, including T cell activation and migration, macrophage polarization, dendritic cell activation, natural killer cell cytotoxicity, neutrophil extracellular trap (NET) formation, and B cell antigen discrimination and class-switching to IgA. PIEZO1 emerges as a central regulator that fine-tunes immune responses by integrating signals from the cellular microenvironment, influencing inflammation, pathogen clearance, and metabolic reprogramming. Despite these advances, key questions remain regarding its role in chronic disease, autoimmunity, and cancer immunity. Targeting PIEZO1 presents a promising therapeutic strategy for conditions driven by mechanical stress and immune dysfunction, such as fibrosis, atherosclerosis, and solid tumours, potentially inaugurating a new era of mechano-immunotherapy.\n\nID: 42094351\nTitle: Myo1e/f regulate phagocytic podosomes to promote efficient cup closure in macrophages.\nAbstract: Phagocytosis requires coordinated remodeling of the actin cytoskeleton to generate protrusive and contractile forces that drive target engulfment. Class I myosins Myo1e and Myo1f (Myo1e/f) have been implicated in linking the plasma membrane to the actin network, but their specific roles during Fc-receptor-mediated phagocytosis remain unclear. Using CRISPR-edited RAW 264.7 macrophages lacking Myo1e and Myo1f, we show that double knockout (dKO) cells exhibit markedly reduced uptake of IgG-coated beads, a phenotype that is partially rescued by re-expression of either myosin. Lattice-light-sheet and confocal imaging revealed distinct F-actin architectures corresponding to the various stages of cup progression, including basal podosome-like adhesions, individual phagocytic podosomes (actin teeth) along the rim of the cup, and a contractile phagocytic ring formed by the reorganization of podosomes into a higher-order network. In Myo1e/f-deficient cells, podosome formation was diminished, actin teeth were largely absent, and the phagocytic ring formed prematurely, which was often accompanied by stalled cup progression and repeated engulfment attempts. Myo1e/f localized both to podosomes and to the inner surface of the phagocytic ring, non-muscle myosin II (NM2) localized to the outer surface, and the absence of Myo1e/f correlated with the diffuse distribution of NM2. In addition, Myo1e/f-deficient macrophages exhibited increased trogocytosis of antibody-opsonized HL-60 cells, indicating a shift from whole-target engulfment toward partial target ingestion. These results suggest that Myo1e/f coordinate spatial and temporal transitions between protrusive and contractile actin networks, thereby ensuring efficient phagocytic cup progression. Our findings highlight a dual role for Myo1e/f in adhesion regulation and force balance during macrophage phagocytosis.\n\nID: 42088827\nTitle: Targeting microglia microtubules: cytoskeletal remodeling as a druggable hub in neuroinflammation and neurodegeneration.\nAbstract: Microglia dynamically remodel their cytoskeleton to surveil the brain, respond to injury, and shape synaptic connectivity. While actin drives rapid process motility and phagocytic cup formation, emerging evidence indicates that microtubules are critical regulators of microglial morphology, trafficking, and inflammatory signaling. In homeostatic microglia, microtubules are nucleated at Golgi outposts, supporting ramified architectures and low inflammatory tone. Upon activation, microglia undergo a switch to a centrosome-nucleated, radial microtubule array, driven in part by cyclin-dependent kinase 1 (Cdk1) and associated with polarized cytokine release, NLRP3 inflammasome engagement, and altered phagocytic behavior. We discuss how key regulators of this transition-including Cdk1, centrosomal \u03b3-tubulin recruitment, Golgi-derived microtubule nucleation, and the kinase MARK4 may constitute druggable nodes to tune microglial reactivity in neuro-degenerative diseases. Finally, we outline experimental priorities for translating microglial microtubules into therapeutic targets.\n\nID: 41950296\nTitle: A biophysical model of phagocytic cup dynamics: The effect of membrane tension.\nAbstract: Phagocytosis is a fundamental cellular process by which cells engulf external particles, controlled by receptor-ligand binding and actin-driven membrane dynamics. While a number of mathematical models have been developed to describe this process, they often overlook membrane tension, a key physical parameter known to influence membrane deformation and cytoskeletal behaviour. To address this gap, we present an enhanced mathematical model of receptor motion during phagocytosis that explicitly incorporates the role of membrane tension. Further, we introduce a signalling component that is coupled to receptor dynamics via the membrane tension. We find that including tension results in fundamentally different engulfment behaviour, which is slower than that predicted by models without tension. In particular, unlike in the previous version of this model, we show that tension can lead to stalled engulfment, an experimentally-observed phenomenon known as frustrated phagocytosis. We also find that signalling is able to modify engulfment behaviour, especially at later stages, and is able to alter cup growth to become linear in time without the need for receptor drift as introduced in previous models. These findings offer new insights into the role of membrane tension and biophysical regulation in phagocytosis, with implications for immune function, cell motility and targeted drug delivery.\n\nID: 41825123\nTitle: Load-independent ceiling of single-target phagocytic membrane extension revealed by microneedle backtracking assay in macrophages.\nAbstract: The zipper model describes the ligand-receptor-driven progression of the phagocytic cup during macrophage engulfment. However, whether the maximum engulfment achievable for a single target is altered by prior or concurrent phagocytic events (i.e., intracellular phagocytic load) remains unclear. Here, we used IgG-coated, nondigestible glass microneedles as standardized Fc\u03b3 receptor ligands and defined the single-target engulfment ceiling as the membrane extension length at which backtracking begins. We then tested whether this ceiling changes after macrophages internalize increasing numbers of IgG-coated polystyrene beads. Across cells, the maximum membrane extension on a microneedle was quantitatively unchanged regardless of the number of internalized indigestible beads. Within the same cell, additional bead ingestion - up to the maximal bead-phagocytosis limit - did not measurably alter the maximum extension achieved on a microneedle. These data establish a load-independent ceiling for single-target engulfment. This invariance suggests that local membrane recruitment and extension are regulated independently of the cell-wide phagocytic burden, supporting a spatially compartmentalized control mechanism that decouples single-target membrane extension from the total intracellular cargo load.\n\nID: 41809010\nTitle: Digest before Ingest: Early Recruitment of Membrane-bound DNaseX to Phagocytic Cups in Macrophages.\nAbstract: Macrophages engulf and degrade pathogens and cellular debris through phagocytosis. The degradation process was generally believed to occur only after phagosome internalization and maturation. Here, we report an early DNase activity at the nascent phagocytic cup (PC) prior to its closure. Using a fluorescent DNase sensor, we revealed rapid and ubiquitous DNase activity upon PC formation across various macrophage types. We further identified the responsible enzyme as the membrane-bound DNaseX, which is constitutively recruited to the PC during PC formation. Although F-actin polymerization is dispensable for DNaseX recruitment, it is essential for its enzymatic activity, likely by promoting physical engagement of DNaseX with solid DNA materials. Functionally, we show that macrophages degrade extracellular DNA (eDNA) within bacterial biofilms through direct physical contact, clearing the eDNA structures without internalization. These findings reveal a previously unrecognized DNA degradation mechanism operating at the macrophage membrane, suitable for degrading bulky eDNA materials which cannot be directly internalized by macrophages.\n\nID: 41638907\nTitle: Syk activation during Fc\u03b3R-mediated phagocytosis involves Syk palmitoylation and desulfenylation.\nAbstract: The Syk tyrosine kinase acts downstream of several immune receptors such as the Fc\u03b3R. Syk owns two SH2 domains that interact with biphosphorylated ITAMs of the Fc\u03b3R upon phagocytosis. This results in the activation of Syk by autophosphorylation, triggering phosphorylation of several downstream targets, F-actin polymerization, and phagocytosis of the IgG-opsonized target. We found that Syk is S-acylated upon phagocytosis by macrophages. Palmitoylation is performed on a single Syk-Cys by the DHHC5 enzyme that specifically associates with Syk upon phagocytosis. Syk palmitoylation is important for Syk localization to the phagocytic cup, phosphorylation, and phagocytosis. We observed that another Syk-Cys residue, within a redox motif, is modified by sulfenylation. Nevertheless, Syk desulfenylation seems to occur during phagocytosis, when H2O2 production at the cup decreases, after 3.5 min of phagocytosis. Molecular dynamics studies indicated that desulfenylation increased the exposure of a loop within the Syk interdomain B. This could facilitate phosphorylation of key Syk-Tyr residues by upstream kinases. We thus propose an updated model for Syk activation during Fc\u03b3R-mediated phagocytosis that involves both Syk palmitoylation and desulfenylation.\n\nID: 41598208\nTitle: Macrophage Plasticity and Regulatory Networks During the Transition from Inflammation to Fibrosis in the Kidney.\nAbstract: Kidney fibrosis represents the final common pathway of nearly all progressive renal diseases, linking acute kidney injury (AKI) and chronic kidney disease (CKD) through a maladaptive repair process. Regardless of etiology, persistent inflammation and excessive extracellular matrix (ECM) deposition drive irreversible structural distortion and functional decline in the kidney. Among cellular mediators, macrophages occupy a central role across the continuum from acute injury to fibrosis, orchestrating both tissue injury and repair through dynamic transitions between pro-inflammatory (M1) and pro-fibrotic (M2) states in response to local cues. Here, we synthesize macrophage-driven mechanisms of renal fibrosis, emphasizing recruitment, infiltration, and local proliferation mediated by chemokine-receptor networks and mechanosensitive ion channels. In addition, in this review paper, we provide an overview on the dual roles of macrophages in acute inflammation and chronic remodeling through key cytokine signaling pathways (TLR4/NF-\u03baB, IL-4/STAT6, TGF-\u03b2/Smad, IL-10/STAT3), highlighting how metabolic reprogramming, mechanochemical feedback via Yes-associated protein (YAP)/transcriptional coactivator with PDZ-binding motif (TAZ) signaling, and epigenetic modulators collectively stabilize the fibrotic macrophage phenotype. Also, emerging insights into mitochondrial dysfunction, succinate-succinate receptor 1 (SUCNR1) signaling, and autophagy dysregulation reveal the metabolic basis of macrophage persistence in fibrotic kidneys. Understanding these multilayered regulatory circuits offers a framework for therapeutic strategies that selectively target macrophage-dependent fibrogenesis to halt the transition from acute injury to chronic renal failure.\n\nID: 41485574\nTitle: Nrf2 deficiency in myeloid cells accelerates atherosclerosis by promoting the inflammatory response and impairing efferocytosis.\nAbstract: Atherosclerotic lesions are the fundamental pathologies of cardiovascular diseases. The exact role of the nuclear factor erythroid 2-related factor 2 (NRF2) in macrophages in atherosclerosis remains uncertain. This study aimed to investigate the role of NRF2 in myeloid cells in the development of atherosclerosis. Single-cell RNA sequencing databases were used to explore the expression levels of NRF2 in human and murine atherosclerosis. Plaque areas, necrotic core size, instability index, and efferocytosis in aortic lesions were investigated in myeloid cell-specific Nrf2-knockout mice on an ApoE-deficient background (Nrf2(M)-KO; ApoE-/-). Transcriptomic, proteomic and chromatin immunoprecipitation (ChIP)-PCR analyses were used to unravel the underlying mechanism. Efferocytosis assays and mRNA levels were verified in primary macrophages and cell lines. NRF2 expression was upregulated in the macrophages of human and murine atherosclerotic arteries compared with their corresponding controls. Nrf2(M)-KO; ApoE-/- mice developed severe atherosclerosis lesions throughout the aorta and aortic sinus with concomitant increases in macrophage accumulation, inflammation, damage-associated molecular patterns release, necrotic core and apoptotic cell accumulation, suggesting that disrupted macrophage efferocytosis may be involved in the pathogenesis. In vitro and in vivo studies showed that Nrf2 deficiency inhibited macrophage efferocytosis. Transcriptomics, proteomics, and in vitro experiments were conducted in primary macrophages isolated from Nrf2(M)-KO mice to unravel the underlying mechanism. We demonstrated that Nrf2 binds to the Myh9 promoter, and that reduced Myh9 accumulation at the phagocytic cup underlies the defective efferocytosis seen in Nrf2-deficient macrophages. Pharmacological activation of NRF2 with 4-octyl itaconate alleviated inflammation and enhanced efferocytosis, but these restorative effects were abolished in Nrf2-KD cells, confirming the NRF2 dependence. Myeloid-specific deletion of Nrf2 promotes inflammation and inhibits macrophage efferocytosis, thereby leading to the aggravation of atherosclerosis. NRF2 activation in macrophages could be a valuable strategy for preventing and treating atherosclerosis.\n\nID: 41346705\nTitle: Piezo1 induces Wnt7b+ astrocytes transformation to modulate glial scar stiffness and neuro-regeneration after stroke.\nAbstract: Background: Reactive astrocytes form a chemical and mechanical glial scar that inhibits neuro-regeneration after stroke. Astrocyte heterogeneity is accompanied by changes in morphology and mechanical properties altering during scar formation after injury. This work aimed to elucidate the relationship between glial scar stiffness and astrocyte subtype transformation. Methods: Astrocyte-specific archaerhodopsin-3 and channelrhodopsin-2 knock-in C57BL/6J mice underwent distal MCAO. Atomic force microscopy, ultrasound elastography and synchrotron radiation were used to determine changes in glial scar stiffness. A proteomic analysis of astrocyte subtypes was performed ex vitro using single-cell laser capture microdissection-MS. Furthermore, optogenetics was employed in vivo to reduce the glial scar stiffness, thereby facilitating neural regeneration following brain injury. Results: Glial scar stiffness systematically increases following stroke and correlates with an increased number of Wnt7b+ fibrotic astrocytes. Furthermore, these results indicate that Piezo1 is the key regulator of astrocytic stiffness and anisotropy, which contributes to the glial scar stiffness in the peri-infarct area. The downregulation of Piezo1 expression promotes activation of the Wnt7b-Ca2+ nonclassical signaling pathway to modulate cytoskeletal reorganization. Finally, the specific optogenetic inhibition of Ca2+ signaling in astrocytes can effectively reduce glial scar stiffness by decreasing the proportion of Wn7b+ astrocytes, which further promotes neuro-regeneration and improves the recovery of motor function after ischemic stroke. Conclusions: This study successfully revealed astrocyte subtype transformation as a key determinant of glial scar physical barrier formation after stroke and highlighted Piezo1 as a potential therapeutic target for modulating the mechanical microenvironment post-injury.\n\nID: 41340053\nTitle: Long-tailed class I myosins rely on tail-mediated phosphoinositide recognition for specific membrane recruitment.\nAbstract: Class I myosins are essential mediators of membrane-cytoskeleton interactions that support key cellular processes such as endocytosis, secretion, intracellular trafficking, and mitosis. However, the mechanisms driving isoform-specific targeting to membrane domains enriched in signaling lipids as well as their stage-dependent recruitment to mitotic structures during cell division remain poorly defined. Using Dictyostelium discoideum as a highly phagocytic cell model, we demonstrate that long-tailed myosin-1 isoforms (myosin-1B, -1C, and -\u20091D) exhibit distinct lipid and cytoskeletal binding profiles shaped by their modular tails and variations within the phosphoinositide binding motif. Homology-based structural modelling of the PH-like lipid binding domain within the TH1 sequence, combined with molecular docking explains their differential lipid affinities. Kinetic equilibrium modelling with quantitative data suggests these differences enable cooperative or competitive isoform localization within cells providing a mechanism for temporally controlled recruitment of the myosins in response to dynamic changes in membrane composition and expression profiles. These biochemical insights are corroborated by confocal live-cell imaging, which reveals phosphoinositides-dependent localization dynamics and isoform-specific targeting of the myosins during vegetative growth and mitotic progression. Myosin-C exhibits phosphoinositide binding preferences nearly reciprocal to those of myosin-1D, especially between mono- and triple phosphorylated phosphoinositides, and shows the strongest tail-mediated, ATP-independent actin binding. Myosin-1B, in contrast, displays low affinity for monophosphorylated phosphoinositides, intermediate actin binding ability, and no microtubule interaction. The comparable affinities of all three myosins for PI(3,5)P\u2082 and PI(4,5)P\u2082, the major PIP species at the cell cortex, facilitate their accumulation at membrane protrusions. Live-cell imaging confirms that myosin-1D preferentially associates with PI(3,4,5)P\u2083- and PI(3)P-enriched endosomes during macropinocytosis and phagocytosis, consistent with its higher binding affinity for these phosphoinositides. Conversely, myosin-1C localization is governed by both actin and phosphoinositides, enabling a rapid dissociation from early endosomes to retarget the cortex and accumulate at actin-rich phagocytic cup tips. Upon mitotic entry, myosin-1D, similar to myosin-1C, redistributes from endosomal compartments to the mitotic apparatus, where it decorates membrane-enclosed nuclear chromatin masses through its TH1 domain and later associates with spindle pole microtubules. This contrasts with myosin-1C, which selectively targets spindle microtubules throughout mitosis, reflecting its stronger microtubule-binding affinity. Inhibition of PI3-kinase disrupts membrane recruitment of both isoforms, confirming their phosphoinositide-dependent localization. These findings reveal an isoform-specific mechanism underlying myosin-1 targeting during endocytosis and mitosis. Collectively, these findings establish a phosphoinositide- and cytoskeleton-guided mechanism that governs myosin-1 isoform-specific functions, providing new insights into how motor proteins interpret complex lipid and cytoskeletal cues to regulate membrane remodelling and cytoskeletal dynamics across cellular states.\n\nID: 41279535\nTitle: Quantifying the fitness contribution of phagocytosis.\nAbstract: Phagocytosis, the ingestion of cells by other cells, is ubiquitous among eukaryotic life. It is required for food uptake in many single-celled species and for the immune response in multicellular species. The origin of phagocytosis and its role in the evolution of endomembranes and the eukaryotic cell remains obscure. Drawing on a wealth of empirical data, we integrate prey capture, engulfment, and internal and external digestion into a mathematical evolutionary model that quantifies the fitness of a primitive phagocytoser relative to a non-phagocytosing ancestor. We reveal the conditions under which a non-phagocytosing predator that digests its prey externally can persist. We also show that the phagocytoser can outperform the ancestor in a broad range of situations, despite the cost associated with producing a phagocytic cup. Parameter variations delineate how fast engulfment needs to be for phagocytosis to be advantageous, providing clear benchmarks for interpreting the importance of results in genetic knockout studies and mechanical models. The phagocytoser still outperforms the ancestor when food vacuoles can't fuse back to the plasma membrane, providing arguments in favor of the gradual evolution of phagocytosis and for phagocytosis as the initiator of the endomembrane system.\n\nID: 41214880\nTitle: Piezo1 Upregulation in Monocyte-Derived Macrophages Impairs Post-Myocardial Infarction Cardiac Repair via Defective Efferocytosis and Enhanced Ferroptosis.\nAbstract: The regulation of macrophage function, particularly that of monocyte-derived macrophages (MoMs), by mechanical forces during myocardial infarction (MI) remains poorly understood. Consistently upregulated Piezo1 expression in cardiac macrophages and MoMs post-MI is found. Elevated Piezo1 expression in MoMs directly contributes to increased Piezo1 levels in cardiac macrophages. Myeloid cell-specific Piezo1-deficient mice (Piezo1Lyz2) exhibit significant improvements in ventricular function/remodeling after MI, accompanied by decreased apoptotic cardiomyocytes and decreased inflammation, increased numbers of macrophages, and increased border zone efferocytosis. In vitro, Piezo1 activation by Yoda1 increased oxygen-glucose deprivation (OGD)-induced ferroptosis and impaired MoM efferocytosis. Conversely, Piezo1 deficiency in MoMs decreases ferroptosis and increases efferocytosis. SLC7A11 is shown to mediate Piezo1-induced defective efferocytosis in MoMs. Piezo1 activation aggravated OGD-induced macrophage ferroptosis via Ca2+ influx followed by SLC15A3 upregulation. Piezo1 upregulated SLC7A11 in macrophages via a Ca2+/ATF4-dependent pathway. MoM-specific SLC7A11 knockdown significantly increases efferocytosis, reduces cardiomyocyte apoptosis and inflammation, and ameliorates post-MI left ventricular remodeling and function. In conclusion, early Piezo1 activation in MoMs is identified during MI, which governs the fate and function of recruited macrophages. These data establish an ischemic heart-bone marrow functional network and provide a novel therapeutic strategy in which MoM Piezo1 is targeted for post-MI heart repair.\n\nID: 41208482\nTitle: The MYO1F interactome reveals ASAP1, CD2AP and SH3KBP1 as novel adaptor proteins in podosomes and phagosomes.\nAbstract: MYO1F, a long-tailed myosin of class I, is selectively expressed in immune cells and upregulated in microglia associated with neurodegenerative pathogenesis. Myosin motor functions are regulated by adaptor proteins that mediate cargo attachment and motor recruitment. To define the MYO1F interactome, we used in situ proximity labelling and proteomics in human myeloid cells. We identified a distinct SH3-domain-dependent adaptor module comprising CD2AP, ASAP1, SH3BP2 and SH3KBP1 (herein termed the CASS group of proteins). Interestingly, CD2AP is an Alzheimer's disease (AD) risk gene upregulated in the microglia of individuals with AD, which are implicated in phagocytic responses to amyloid-\u03b2. Structural modelling and mutagenesis confirmed multivalent proline-rich motif interactions between the CASS group of proteins and the MYO1F SH3 domain. Additional binding partners associate with the MYO1F pleckstrin homology (PH) domain. Immunofluorescence revealed colocalisation of MYO1F and the CASS group of proteins at actin-rich podosomes and phagocytic cups in macrophages and microglia. Functional assays demonstrated that MYO1F recruitment to the phagocytic cup requires motor activity and intact PH and SH3 domains. We provide the first MYO1F interactome identifying adaptor proteins for MYO1F in podosomes and during phagocytosis, offering new insights into its function in disease-associated microglia during neurodegeneration.\n\nID: 41071099\nTitle: Mechanosensitive ion channels as novel targets in osteoporosis.\nAbstract: Osteoporosis is the most prevalent metabolic bone disease globally, leading to an increased risk of fractures. Recent advances in ion channel research have shed light on the importance of mechanosensitive ion channels as novel players in these pathophysiological processes. This perspective discusses the involvement of the mechanosensitive ion channels TREK-1, Piezo, and volume-regulated anion channels (VRACs) as potential novel pharmacological targets for the treatment of osteoporosis. TREK-1, a mechanosensitive K2P channel is important for maintaining the resting membrane potential in many cells, including osteoblasts and osteoclasts. K2P channels regulate osteoblast proliferation and differentiation, as well as osteoclast activity, potentially modulating bone remodeling in osteoporosis. Piezo channels influence osteoblast differentiation and osteoclast activity by modulating calcium influx, which is crucial for osteogenic signaling pathways, such as Wnt/\u03b2-catenin and ERK1/2. Piezo1 activation promotes bone formation, while its deficiency leads to impaired osteogenesis and increased bone resorption. Volume-regulated anion channels have been shown to be involved in osteoblast adaptation to mechanical stress and macrophage polarization, which indicates their importance for bone homeostasis. Chronic inflammation is a major contributor to osteoporosis progression. Evidence of ion channel involvement in this process has emerged in recent years. Specifically, macrophage function in osteoporosis seems to be linked to ion channel activity. Inflammatory polarization of macrophages is a key player in inflammation-induced bone loss and can be driven by mechanosensitive ion channels. Modulating these ion channels may provide new therapeutic opportunities. Given the complexity of ion channel interactions in bone cells and their regulatory role in bone remodeling, understanding their precise function in osteoporosis is essential. Targeted modulation of mechanosensitive ion channels holds promise as a novel therapeutic approach to mitigate inflammation-driven bone loss and improve bone density. Further research into their role in osteoclasts and macrophage-driven bone degradation will aid in developing innovative osteoporosis treatments. Osteoporosis is the most common bone disease worldwide. The exact reasons for why bones weaken is often not fully understood, which makes the development of targeted therapies difficult. Our article highlights a new perspective: certain proteins in bone cells, called mechanosensitive ion channels, may be key players in osteoporosis. These channels act like tiny \u201cgates\u201d in the cell membrane that open when cells are stretched, thereby regulating the activity of cells. They help bone cells and immune cells sense their environment and respond to changes. We focus on three groups of these channels: K2P channels influence how bone-building cells (osteoblasts) grow and how immune cells control inflammation. Piezo channels help bone cells sense mechanical forces and control immune cell behavior. Volume-regulated anion channel channels may help bone cells adapt to stress and regulate inflammatory signals. Because of their dual effect on mechanical and inflammatory signaling, changes/alterations in ion channel activity may contribute to bone loss in osteoporosis. Pharmacological targeting of these channels could therefore help to protect bone. Early studies suggest that drugs influencing mechanosensitive ion channels might one day prevent or slow down osteoporosis. More research is needed, but this approach opens exciting new possibilities for treatment.\n\nID: 40741709\nTitle: Depletion of endomembrane reservoirs drives phagocytic appetite exhaustion in macrophages.\nAbstract: During phagocytosis, a phagocytic cup grows via F-actin remodeling and localized secretion to entrap a particle within a phagosome, which then fuses with endosomes and lysosomes to digest the particle, followed by phagosome resolution. As spatially limited systems, phagocytes have a maximal phagocytic capacity, at which point further uptake must be reduced. However, the processes responsible for phagocytic appetite exhaustion as phagocytes reach their maximal phagocytic capacity are poorly defined. We found that macrophages at their capacity have lower surface levels of Fc\u03b3 receptors but overexpression of these receptors did not increase their capacity, suggesting that receptor levels are not limiting. We found that surface membrane in-folding, membrane tension and cortical F-actin were all reduced in exhausted macrophages. Although this might contribute to appetite suppression, we also found that 'free' endosomes and lysosomes were severely depleted in exhausted macrophages. Consequently, focal exocytosis at sites of externally bound particles was reduced. In comparison, macrophages recovered their appetite if phagosome resolution was permitted. We propose that depletion of the endomembrane pools is a major determinant of phagocytic fatigue as macrophages reach their phagocytic capacity.\n\nID: 40720339\nTitle: Exploring the Sequential Cellular Events of Phagocytosis Triggered by Godanti Bhasma in Mammalian Cells.\nAbstract: Phagocytosis is a vital cellular mechanism through which cells engulf and degrade foreign particles, pathogens, or debris, playing a key role in immune defense and the maintenance of tissue homeostasis. Disruptions in this process are associated with various diseases. To explore the complex events involved in the phagocytosis pathway, advanced smart particles and effective monitoring techniques are essential. Godanti Bhasma (GB), a traditional Indian medicine composed of bioactive calcium sulfate particles, is rapidly internalized by phagocytosis in mammalian cells, inducing significant cytoplasmic vacuolation. The key stages of GB-induced phagocytosis were evaluated here using flow cytometry (FC), live-cell imaging, and specific staining techniques. Flow cytometric analysis demonstrated the formation of phagocytic cup-like structures associated with particle internalization. Live-cell imaging enabled real-time observation of phagocytic processes, including particle uptake, vacuole formation, degradation of engulfed materials, and vacuolar turnover. Staining with neutral red and acridine orange was employed to assess vacuolar acidification. Interestingly, treatment with the lysosomal inhibitor BFA1 in GB-treated cells did not lead to vacuolation, as evidenced by the lack of neutral red uptake, emphasizing the requirement for an acidic environment for vacuolation to occur. These findings underscore the potential of GB-induced phagocytosis as a model to elucidate the sequential cellular events involved in this process, which is critical for understanding host-pathogen interactions, intracellular trafficking, and developing innovative therapeutic strategies for disorders related to phagocytosis.\n\nID: 40517844\nTitle: Mechanical stretch-mediated fibroblast activation: The pivotal role of Piezo1 channels.\nAbstract: Mechanical forces are crucial in regulating fibroblast behavior, yet the underlying mechanisms remain unclear. This study aims to elucidate the role of the Piezo1 ion channel in fibroblast responses to mechanical stimulation. A mechanical stimulation culture platform was developed using a polydimethylsiloxane (PDMS)-based stretchable membrane and the Cell Tank uniaxial cell stretching system. Fibroblasts subjected to uniaxial cyclic stretching were analyzed using proteomic profiling, Western blotting, and confocal laser scanning microscopy to assess cytoskeletal changes and activation markers. Immunofluorescence staining was performed to evaluate the expression of Piezo1, YAP1, and Ki67 proteins. Cell viability and migration capacity were assessed using Calcein-AM/PI double staining and a migration assay. Mechanical stretch-induced fibroblast activation is characterized by morphological changes, increased proliferation, and enhanced migration. The cytoskeletal reorganization was observed, with elevated F-actin expression. Modulating Piezo1 activity altered fibroblast activation, indicating its essential role in mechanotransduction. These findings demonstrate that mechanical stretch upregulates Piezo1 expression, promoting fibroblast activation through the YAP pathway. This study provides new insights into the mechanotransduction mechanisms in fibroblasts and highlights the critical role of Piezo1 in mediating responses to mechanical stimuli, which may have implications for understanding tissue remodeling and fibrosis.\n\nID: 40429901\nTitle: Formation of Membrane Domains via Actin Waves: A Fundamental Principle in the Generation of Dynamic Structures in Phagocytes.\nAbstract: Phagocytes carry out their functions by organizing new subcellular structures. During phagocytosis, macrophages internalize and degrade pathogens and apoptotic cells by forming the phagocytic cup and phagosome. Osteoclasts resorb bone by forming the sealing zone and ruffled border at the ventral membrane. This review explores the organizational principles of these dynamic structures. In in vitro frustrated phagocytosis, specifically 2D phagocytosis by macrophages, the activation of the Fc\u03b3 receptor generates multiple self-organized waves containing F-actin, Arp2/3, and phosphoinositides. The propagation of these circular actin waves segregates the inside from the outside, leading to the compartmentalization of the ventral membrane. As the actin wave passes, cortical actin is disrupted, and membrane remodeling occurs within the wave, creating a new membrane domain with high exocytic activity. These processes mirror the formation of the constriction zone in the phagocytic cup and phagosome during 3D phagocytosis. A similar mechanism may also contribute to the formation of the sealing zone and ruffled border in osteoclasts. Based on these observations, we propose that dynamic structures formed from actin waves are organized through the fractal integration of self-organized, oscillatory substructures, with F-actin treadmilling fueling their formation and maintenance.\n\nID: 39389940\nTitle: Stage-specific modulation of multinucleation, fusion, and resorption by the long non-coding RNA DLEU1 and miR-16 in human primary osteoclasts.\nAbstract: Osteoclasts are the only cells able to resorb all the constituents of the bone matrix. While the modulation of osteoclast activity is well established for preventing bone-related diseases, there is an increasing demand for novel classes of anti-resorption agents. Herein, we investigated non-coding RNA molecules and proposed DLEU1 and miR-16 as potential candidates for modulating osteoclast functions. DLEU1 and miR-16 target cell fusion at both the early and late stages of osteoclastogenesis but operate through independent pathways. DLEU1 silencing hinders the fusion process, leading to abrogation of the phagocytic cup fusion modality and a reduction in the fusion events between mononucleated precursors and multinucleated osteoclasts, while miR-16 influences monocyte-to-osteoclast differentiation, impairing osteoclasts formation but not the number of nuclei at early stages. On the other hand, using these non-coding RNAs to engineer mature osteoclasts has implications for bone resorption. Both DLEU1 and miR-16 influence the speed of resorption in pit-forming osteoclasts, without affecting the resorbed area. However, the impact of increasing miR-16 levels extends more broadly, affecting trench-forming osteoclasts as well, leading to a reduction in their percentage, speed, and resorbed area. These findings offer potential new therapeutic targets to ameliorate bone destruction in skeletal diseases.\n\nID: 39294148\nTitle: \u03b22 integrins impose a mechanical checkpoint on macrophage phagocytosis.\nAbstract: Phagocytosis is an intensely physical process that depends on the mechanical properties of both the phagocytic cell and its chosen target. Here, we employed differentially deformable hydrogel microparticles to examine the role of cargo rigidity in the regulation of phagocytosis by macrophages. Whereas stiff cargos elicited canonical phagocytic cup formation and rapid engulfment, soft cargos induced an architecturally distinct response, characterized by filamentous actin protrusions at the center of the contact site, slower cup advancement, and frequent phagocytic stalling. Using phosphoproteomics, we identified \u03b22 integrins as critical mediators of this mechanically regulated phagocytic switch. Macrophages lacking \u03b22 integrins or their downstream effectors, Talin1 and Vinculin, exhibited specific defects in phagocytic cup architecture and selective suppression of stiff cargo uptake. We conclude that integrin signaling serves as a mechanical checkpoint during phagocytosis to pair cargo rigidity to the appropriate mode of engulfment.\n\nID: 38873703\nTitle: Biomechanism of abnormal stress on promoting osteoarthritis of temporomandibular joint through Piezo1 ion channel.\nAbstract: This study aimed to investigate whether flow fluid shear stress (FFSS)-mediated signal transduction affects the function of Piezo1 ion channel in chondrocyte and to further explore the role of mechanical overloading in development of temporomandibular joint osteoarthritis (TMJ OA). Immunohistochemical staining was used to determine the expression of Piezo1 in TMJ OA tissue collected from rat unilateral anterior crossbite (UAC) models. Chondrocytes harvested from normal adult SD rats were treated with FFSS (0, 4, 8, 12\u2009dyn/cm2) in\u00a0vitro. Immunofluorescent staining, real-time polymerase chain reaction, western blotting, flow cytometry and phalloidin assay were performed to detect the changes of cellular morphology as well as the expression of Piezo1 and certain pro-inflammatory and degradative factors in chondrocyte. Immunohistochemical analysis revealed that significantly increased Piezo1 expression was associated with UAC stimulation (p\u2009<\u2009.05). As applied FFSS escalated (4, 8 and 12\u2009dyn/cm2), the expression levels of Piezo1, ADAMTS-5, MMP-13 and Col-X gradually increased, compared with the non-FFSS group (p\u2009<\u2009.05). Administering Piezo1 ion channel inhibitor to chondrocytes beforehand, it was observed that expression of ADAMTS-5, MMP-13 and Col-X was substantially decreased following FFSS treatment (p\u2009<\u2009.05) and the effect of cytoskeletal thinning was counteracted. The activated Piezo1 ion channel enhanced intracellular Ca2+ excess in chondrocytes during abnormal mechanical stimulation and the increased intracellular Ca2+ thinned the cytoskeleton of F-actin. Mechanical overloading activates Piezo1 ion channel to promote pro-inflammation and degradation and to increase Ca2+ concentration in chondrocyte, which may eventually result in TMJ OA.\n\nID: 38838160\nTitle: Stiffness sensing via Piezo1 enhances macrophage efferocytosis and promotes the resolution of liver fibrosis.\nAbstract: Tissue stiffening is a predominant feature of fibrotic disorders, but the response of macrophages to changes in tissue stiffness and cellular context in fibrotic diseases remains unclear. Here, we found that the mechanosensitive ion channel Piezo1 was up-regulated in hepatic fibrosis. Macrophages lacking Piezo1 showed sustained inflammation and impaired spontaneous resolution of early liver fibrosis. Further analysis revealed an impairment of clearance of apoptotic cells by macrophages in the fibrotic liver. Macrophages showed enhanced efferocytosis when cultured on rigid substrates but not soft ones, suggesting stiffness-dependent efferocytosis of macrophages required Piezo1 activation. Besides, Piezo1 was involved in the efficient acidification of the engulfed cargo in the phagolysosomes and affected the subsequent expression of anti-inflammation genes after efferocytosis. Pharmacological activation of Piezo1 increased the efferocytosis capacity of macrophages and accelerated the resolution of inflammation and fibrosis. Our study supports the antifibrotic role of Piezo1-mediated mechanical sensation in liver fibrosis, suggesting that targeting PIEZO1 to enhance macrophage efferocytosis could induce fibrosis regression.\n\nID: 42564426\nTitle: FAP-derived CCL2 is required for adequate monocyte/macrophage infiltration to support acute skeletal muscle injury repair.\nAbstract: Repair of acutely injured skeletal muscle relies on an adequate inflammatory response predominated by monocyte/macrophage infiltration. The process requires injured muscles to produce C-C chemokine ligand 2 (CCL2). The present study identified fibro/adipogenic progenitors (FAPs) as the primary source of CCL2 in acutely injured muscle, where the pro-inflammatory subcluster of FAPs expanded rapidly and expressed the highest level of CCL2. FAP-specific deletion of Ccl2 largely abolished CCL2 production by acutely injured muscle, reducing monocyte/macrophage infiltration and impairing muscle regeneration. In vitro, the CCL2 expression by both mouse and human FAPs was induced by danger signal-containing muscle homogenates through Toll-like receptor signaling. The CCL2 expression by mouse FAPs was also induced by infiltrating neutrophils, partly through their secretion of pro-inflammatory cytokines. Our findings suggest an important immune sentinel role for FAPs, as they sense muscle damage, produce CCL2 to recruit inflammatory monocytes, and promote injury repair.\n\nID: 42564368\nTitle: Pediatric Repetitive Mild Traumatic Brain Injury Elicits T Cell-Mediated Neuroinflammation.\nAbstract: Pediatric repetitive mild traumatic brain injury (rmTBI) is a major public health concern with links to chronic cognitive dysfunction. Neuroinflammation represents a significant maladaptive outcome after rmTBI. Persistent innate and adaptive immune cell responses can lead to neurodegeneration and deficits in brain development. Therefore, a deeper understanding of the early dynamics of peripheral immune cell infiltration after pediatric rmTBI is critical for the development of effective treatment. We hypothesize that pediatric rmTBI alters neuroinflammation through T cell infiltration. We used wild-type (C57BL/6) and T cell knockout (TCR\u03b2-/- \u03b4-/-) mice to test this hypothesis. We developed a pediatric postnatal day 21 rmTBI model, with three consecutive subconcussive impact acceleration injuries separated in time by 1 week. After inducing rmTBI in juvenile mice, we observed a progressive infiltration of macrophages, CD8+, and CD4+ T cells into the brain parenchyma, which increased with repeated injury. Furthermore, neuroinflammation in the white matter was detected when we analyzed the lateral corpus callosum (CC). Since increased infiltration of CD4+ and CD8+ T cells was detected, we utilized TCR\u03b2-/- \u03b4-/- mice to further explore the role of T cells on neuroinflammation after pediatric rmTBI. We observed a reduction in the infiltration of pro-inflammatory macrophages and decreased neuroinflammation in the lateral CC. Overall, our findings highlight the significant role of T cell infiltration in the modulation of neuroinflammation following rmTBI in the developing brain, suggesting that they may serve as potential therapeutic targets for managing neuroinflammation following pediatric brain injuries.\n\nID: 42564269\nTitle: TNF-\u03b1 blockade with adalimumab restores bone metabolism in rheumatoid arthritis by regulating cytokines and inflammatory cell infiltration.\nAbstract: To investigate the mechanisms underlying the bone-sparing effects of the anti-TNF antibody adalimumab in rheumatoid arthritis (RA) by examining synovial tissue and its direct effect on osteoblasts and osteoclasts. Paired synovial biopsies from 12 patients with RA were obtained before and 8 weeks after initiation of adalimumab. Immune-cell infiltrates (CD163+ macrophages, CD3+ lymphocytes) and expression of osteoprotegerin (OPG), receptor activator of nuclear factor \u03baB (RANK), and its ligand (RANKL) were assessed by immunohistochemistry. In vitro, the effect of adalimumab on RANKL and OPG expression in SaOS-2 cells (\u00b1\u00a0TNF-\u03b1) was evaluated by western blotting. Its effect on osteoclastogenesis and bone resorption were examined using CD14+ monocyte-derived macrophages cultured with RANKL and M-CSF. Adalimumab treatment led to a marked clinical improvement, with median DAS28 decreasing from 5.4 to 3.1. Semiquantitative analysis of synovial biopsies revealed a significant decrease in CD163+ macrophages, while CD3+ T-cells remained unchanged. The RANKL/OPG ratio decreased significantly, which was accompanied by increased OPG expression in synovial tissue. In vitro, adalimumab significantly decreased RANKL expression and the RANKL: OPG ratio in TNF-\u03b1 primed SaOS-2 cells, while also modulating pro-osteoclastogenic cytokines. In osteoclast assays, adalimumab inhibited macrophage-derived osteoclast differentiation and suppressed bone resorption under both low and high RANKL conditions. Adalimumab decreased synovial macrophage infiltration while it modulates pro-osteoclastogenic cytokines and inhibits osteoclastogenesis. These combined effects explain how TNF-\u03b1 blockade ameliorates joint inflammation and prevents structural damage.\n\nID: 42564225\nTitle: A single-cell sequencing-based prognostic model reveals HLA-DRA, NPC2, and PRPF38B as immune-regulatory tumor suppressors in non-small cell lung cancer.\nAbstract: Non-small cell lung cancer (NSCLC) is the most common lung cancer subtype and a leading cause of cancer-related mortality due to asymptomatic early stages and poor 5-year survival, and tumor-infiltrating lymphocytes (TILs) play a pivotal but poorly defined role in NSCLC progression and prognosis within the tumor microenvironment (TME). We analyzed single-cell RNA sequencing data from GEO (GSE148466), NSCLC-related data from TCGA, and gene expression data from GEO (GSE50081). A 9-gene TIL-related risk score model (HLA-DRA, NPC2, PRPF38B, PABPC1, ENO1, ANXA2, LGALS1, S100A10, SRGN) was constructed using LASSO regression, with its prognostic value assessed via Kaplan-Meier and ROC analyses and external validation. Immune infiltration and regulatory factors were analyzed using TISIDB, pathway associations via GSVA and GSEA, and functional roles of key genes (HLA-DRA, NPC2, PRPF38\u00a0B) validated using RT-qPCR, Western blotting, and co-culture assays. TILs were abundant in both smoking and non-smoking NSCLC samples. The 9-gene risk model effectively stratified patients by survival, with high-risk patients showing poorer outcomes and enriched tumor-promoting immune features and pathways. High-risk scores were associated with increased M0 macrophages, activated NK cells, and elevated immune checkpoints. Overexpression of HLA-DRA, NPC2, and PRPF38\u00a0B inhibited NSCLC cell proliferation, migration, and invasion, while enhancing apoptosis and suppressing M2 macrophage polarization. This study establishes a TIL-based prognostic risk model for NSCLC and identifies HLA-DRA, NPC2, and PRPF38\u00a0B as potential immune-regulatory therapeutic targets with tumor-suppressive functions, providing new insights for NSCLC precision immunotherapy.\n\nID: 42564204\nTitle: Targeting macrophage-mediated TGF-\u03b2/BMP signaling in ankylosing spondylitis: from inflammation to pathological bone formation.\nAbstract: Ankylosing spondylitis (AS) is a chronic, immune-mediated disease characterized by inflammatory arthritis and pathological new bone formation, ultimately leading to spinal fusion and functional impairment. Despite effective suppression of inflammation by biologic agents targeting cytokines such as TNF-\u03b1 and IL-17A, radiographic progression often continues, highlighting a critical dissociation between inflammatory activity and structural damage. The literature suggests that macrophage polarization and the TGF-\u03b2/BMP signaling axis collectively constitute a critical nexus linking inflammation to aberrant osteogenesis in AS. Moreover, it details how the unique entheseal microenvironment-shaped by biomechanical stress, hypoxia, and a distinct cytokine milieu-drives macrophages toward a spectrum of pro-osteogenic phenotypes through a mechano-inflammatory feedback loop. After that, polarized macrophages, in turn, serve as pivotal cellular engineers that locally activate and sustain TGF-\u03b2/BMP signals through proteolytic cleavage and acidic remodeling of the ECM. This self-amplifying loop directly orchestrates endochondral ossification at ligamentous insertion sites, culminating in syndesmophyte formation and spinal ankylosis. Therapeutically, this mechanistic understanding highlights promising avenues for disease modification beyond conventional anti-inflammatory strategies. Targeting macrophage polarization states or disrupting the TGF-\u03b2/BMP activation cascade may offer dual benefits-suppressing both inflammation and structural progression-and pave the way for genuine disease-modifying therapies in AS.\n\nID: 42564166\nTitle: Accumulation of small peritoneal macrophages and dendritic cells in a concomitant immunity model associated with prolonged survival.\nAbstract: This study investigated the contribution of peritoneal macrophages to tumor control using a DBA/2-SL2 murine model of concomitant tumor immunity. Female DBA/2 mice were subjected to a concomitant tumor model in which SL2 lymphoma cells were injected subcutaneously (SC) to establish a primary tumor, followed by intraperitoneal (IP) SL2 challenge to induce secondary tumors. Peritoneal immune cells were analyzed by flow cytometry 4 days after IP challenge. Absolute cell numbers were calculated from total viable cell recovery. To assess functional antitumor activity, CD11b+F4/80+ peritoneal macrophages were isolated by magnetic separation and adoptively transferred into na\u00efve mice together with SL2 cells. In additional experiments, mice received repeated IP injections of SL2 cells. Non-parametric statistical tests were used for data analysis. Prolonged survival in mice with secondary IP SL2 tumors was associated with pronounced alterations in peritoneal immune composition. Flow cytometric analysis revealed a marked accumulation of small peritoneal macrophages (SPMs) and dendritic cells (DCs) in mice with secondary IP tumors. Absolute counts of SPMs (CD11bintF4/80int) and DCs (CD11c+) were significantly increased in the secondary IP tumor group, with a positive, not statistically significant, correlation between these population. In contrast, mice with primary IP tumors showed expansion of CD11c-CD11b- F4/80- cells, which may include SL2 tumor cells, reduced numbers of B lymphocytes (CD19+) and large peritoneal macrophages (LPMs) (CD11bhiF4/80hi) and an increased number of CD11blowF4/80int cells. Adoptive transfer of peritoneal macrophages from mice with secondary IP tumors did not prolong survival. Repeated IP administration of SL2 cells was associated with improved survival in mice bearing SC tumors in 3 of 5 mice, compared with 1 of 5 mice in the SC tumor-only group, although this difference did not reach statistical significance. Prolonged survival of DBA/2 mice with secondary IP SL2 tumors is associated with a distinct peritoneal immune landscape characterized by accumulation of SPMs and DCs. While macrophages alone were insufficient to control tumor growth, repeated IP tumor challenge suggested a trend toward systemic antitumor activity. Collectively, these findings highlight SPMs and DCs as prominent cells associated with survival benefit in this model.\n\nID: 42564162\nTitle: Immunomodulation in the repair of osteonecrosis of the femoral head: reprogramming strategies for macrophages and immune cells.\nAbstract: Osteonecrosis of the femoral head (ONFH) is a severe and debilitating disease that\u00a0substantially affects patients' functional capacity and daily activities. Within necrotic femoral heads, immune cells, particularly macrophages, undergo phenotypic reprogramming. This phenotypic shift in macrophages, along with their interactions with other cell types-including osteoclasts, mesenchymal stem cells, and endothelial cells-collectively mediates disease progression. However, targeted immunotherapeutic strategies remain poorly defined. In this context, the present study reviews recent literature and provides a comprehensive overview of the immunological landscape of macrophages in osteonecrosis of the femoral head (ONFH). It summarizes current knowledge on macrophage immune reprogramming, intercellular interactions with neighboring cells (such as mesenchymal stem cells, osteoclasts, and vascular endothelial cells), and the cellular composition of immune cells (including neutrophils, B cells, and T cells) in ONFH. Furthermore, it explores the potential application of biomaterials developed through various strategies for ONFH treatment. Emerging evidence indicates that the direction of macrophage polarization and their intercellular interactions with diverse cell types (e.g., mesenchymal stem cells, osteoclasts, and vascular endothelial cells), together with the infiltration of immune cells (such as neutrophils, B cells, and T cells), collectively influence the progression of ONFH. On this basis, therapeutic strategies targeting macrophage polarization and immune cell activation are proposed, with a particular focus on biomaterials possessing diverse physicochemical properties, thereby offering insights to facilitate the clinical translation of ONFH treatments.\n\nID: 42564045\nTitle: SR9009 regulates macrophage polarization via the NR1D1/NF-\u03baB axis to ameliorate obesity-associated ulcerative colitis.\nAbstract: The incidence of ulcerative colitis (UC) and obesity has risen in recent years, potentially linked through metabolic dysregulation and chronic inflammation. The nuclear receptor NR1D1 is pivotal in regulating circadian rhythms and plays a significant role in inflammation and metabolism. This study investigates the therapeutic effects and mechanisms of the NR1D1 agonist SR9009 on obesity-related UC. We established a mouse model of obesity-induced UC utilizing a high-fat diet alongside dextran sulfate sodium (DSS). 32 male C57BL/6 mice were divided into four groups: control (DZ), high-fat diet (GZ), obesity associated UC model group (UC), and SR9009 intervention group (JD), with eight mice each. We evaluated body weight, blood lipids, colonic tissue alterations, IL-1\u03b2, IL-18, macrophage polarization, and NR1D1 expression levels. Mice in the UC group demonstrated significantly elevated body weight, spleen index, TG, CHOL and inflammatory markers (P\u00a0<\u00a00.01). Pathological scores of colonic tissues increased markedly (P\u00a0<\u00a00.001), with a rise in M1 macrophages (CD68+) and a decline in M2 macrophages (CD206+) (P\u00a0<\u00a00.001). NR1D1 expression was notably downregulated (P<0.01). Post-SR9009 intervention, the JD group showed significantly reduced serum TG and CHOL levels (P\u00a0=\u00a00.001, 0.011), IL-1\u03b2 and IL-18 (P<0.001), improved colonic pathology (P\u00a0<\u00a00.001), a decrease in M1 macrophages, an increase in M2 macrophages, and an enhanced M1/M2 ratio (P<0.001). SR9009 mitigates intestinal inflammation in obesity associated UC by activating NR1D1, potentially modulating NF-\u03baB-related signaling, and modulating macrophage polarization (suppressing M1 and enhancing M2). These findings propose a novel strategy for targeting NR1D1 in the treatment of obesity-related ulcerative colitis.\n\nID: 42564021\nTitle: Post-transcriptional regulation via alternative polyadenylation and piRNA shapes macrophage responses in psoriasis.\nAbstract: Post-transcriptional regulatory mechanisms underlying autoimmune diseases remain poorly understood. Here, we employed integrated multi-omics approaches to systematically dissect the role of alternative polyadenylation (APA) and piRNA-mediated regulation in psoriasis pathogenesis. We performed transcriptome-wide association studies (TWAS) combined with Mendelian randomization to identify causal susceptibility genes. Long-read sequencing was used to characterize APA landscapes in 15 healthy controls and 10 psoriasis patients. Single-cell RNA sequencing was performed on lesional tissues from 4 patients to define cell-specific expression patterns. Small RNA sequencing was conducted to profile piRNA regulation in LPS + IFN-\u03b3-polarized THP-1 macrophages following TDRKH knockdown. Integrating multi-tissue genetic validations across GTEx, eQTLGen, and FinnGen datasets, we identified TDRKH as a robust psoriasis susceptibility gene (PPH4 > 0.92). TDRKH exhibited significant APA alterations in psoriatic PBMCs, with preferential usage of the distal polyadenylation site leading to 3'UTR lengthening (PDI = -0.574). Reporter gene assays confirmed that the long 3'UTR isoform conferred approximately 3-fold greater mRNA stability (t\u00bd = 6.9\u00a0h vs. 2.3\u00a0h). Single-cell RNA sequencing of psoriatic skin (4 patients, 17,734 cells) identified 17 cell types and 10 macrophage/myeloid subpopulations using marker gene-based annotation with TDRKH excluded from feature selection. TDRKH expression was highest in IL-23-producing macrophages (IL23A+IL1B+), which were selectively enriched in lesional tissue. TDRKH knockdown in LPS + IFN-\u03b3-polarized THP-1 macrophages altered piRNA expression profiles, reduced pro-inflammatory surface markers (CD80, CD86, HLA-DR), and attenuated IL6 and IL1B expression, supporting a functional role of the TDRKH-piRNA axis in macrophage inflammatory activation. Our findings reveal a previously unrecognized post-transcriptional regulatory network involving APA and piRNA that governs macrophage-driven inflammation. The discovery of the TDRKH-piRNA axis provides novel mechanistic insights into psoriasis and establishes a potential therapeutic target.\n\nID: 42563678\nTitle: [Study on cellular repressor of E1A-stimulated genes regulating autophagy and polarization of alveolar macrophages in sepsis-induced acute respiratory distress syndrome and its clinical value].\nAbstract: To investigate the regulatory effects of cellular repressor of E1A-stimulated gene (CREG) on autophagy and polarization of alveolar macrophages in sepsis-induced acute respiratory distress syndrome (ARDS) and its clinical value. 1) Cell experiment: Mouse monocyte/macrophage cell line RAW264.7 was cultured in vitro. Cells in logarithmic growth phase were induced to differentiate into alveolar macrophages. The alveolar macrophages were divided into four groups: the blank control group was cultured with complete medium only; the lipopolysaccharide (LPS) group was stimulated with 5 mg/L LPS for 24 hours to establish the sepsis-induced ARDS model; the CREG overexpression group was transfected with 2 mg CREG overexpression plasmid pLNCX2-CREG for 6 hours, followed by 5 mg/L LPS stimulation for 24 hours; the CREG interference group was transfected with 2 \u03bcg CREG interference plasmid pSM2-siCREG for 6 hours, followed by 5 mg/L LPS stimulation for 24 hours. Western blotting was used to detect the expression of autophagy markers [autophagy initiation key protein Beclin1, microtubule-associated protein 1 light chain 3 (LC3), and autophagic substrate protein p62]. Flow cytometry was used to detect the expression of macrophage polarization markers [M1-type characteristic marker cluster of differentiation 86 (CD86) and M2-type characteristic marker CD206]. 2) Clinical trial: A prospective case-control study was conducted in patients with sepsis admitted to the respiratory intensive care unit of The First Affiliated Hospital of Hebei North University from January to December 2024. Patients were divided into sepsis with ARDS group and sepsis without ARDS group based on whether they developed ARDS within 72 hours after enrollment. In addition, healthy volunteers who underwent health check-ups at the hospital during the same period were selected as the controls. Demographic data including gender, age, Acute Physiology And Chronic Health Evaluation II (APACHE II) score, oxygenation index (PaO2/FiO2), and laboratory parameters were collected for each group, as well as the sites of infection for the septic patients. Serum levels of CREG and inflammatory markers [interleukin-6 (IL-6), tumor necrosis factor-\u03b1 (TNF-\u03b1), procalcitonin (PCT), and C-reactive protein (CRP)] were measured using enzyme-linked immunosorbent assay (ELISA). The differences in the above indicators were compared among groups. Multivariate Logistic regression analysis was used to identify independent influencing factors for sepsis complicated with ARDS. Receiver operator characteristic curve (ROC curve) was plotted to evaluate the predictive value of CREG for sepsis complicated with ARDS. 1) Cell experiment results: Compared with the blank control group, the expressions of Beclin1, LC3-II/LC3-I ratio, and CD206 were decreased in each LPS group [Beclin1 protein (Beclin1/\u03b2-actin): 0.32\u00b10.05 vs. 0.87\u00b10.09, LC3-II/LC3-I ratio: 0.41\u00b10.06 vs. 1.24\u00b10.11, CD206: (27.14\u00b13.52)% vs. (51.78\u00b15.91)%, all P<0.05], while p62 and CD86 expressions were increased [p62 protein (p62/\u03b2-actin): 1.58\u00b10.13 vs. 0.53\u00b10.07, CD86: (38.35\u00b14.67)% vs. (18.26\u00b13.24)%, both P<0.05]. CREG overexpression significantly improved the above autophagy and polarization indicators, whereas CREG interference further exacerbated these indicators (all P<0.05). 2) Clinical trial results: Ultimately, 40 patients were included in the sepsis with ARDS group, 60 in the sepsis without ARDS group, and 20 in the healthy control group. There were no statistically significant differences in gender, age among the three groups, nor in the distribution of infection sites between the sepsis with ARDS and sepsis without ARDS groups (all P>0.05). Compared with the healthy control group, the patients with sepsis showed aggravated systemic inflammatory burden. Compared with the sepsis without ARDS group, the sepsis with ARDS group exhibited more severe disease, with lower PaO2/FiO2 and CREG levels, and higher levels of inflammatory markers (all P<0.05). As APACHE II score increased, serum CREG levels decreased progressively while inflammatory marker levels increased progressively. Multivariate Logistic regression analysis showed that elevated APACHE II score and inflammatory markers were independent risk factors for sepsis complicated with ARDS [all odds ratio (OR) >1, all P<0.05], while elevated CREG was a protective factor [OR=0.385, 95% confidence interval (95%CI) was 0.344-0.432, P=0.015]. ROC curve analysis showed that the area under the ROC curve (AUC) of CREG for predicting sepsis complicated with ARDS was 0.806 (95%CI was 0.713-0.899); at the optimal cut-off value of 7.85 \u03bcg/L, the sensitivity was 71.43% and the specificity was 78.57%. CREG exerts a protective role in sepsis-induced ARDS by positively regulating alveolar macrophage autophagy activity and correcting M1/M2 polarization imbalance. Elevated serum CREG is a protective factor for sepsis complicated with ARDS and has early predictive value for sepsis-induced ARDS.\n\nID: 42563599\nTitle: 3D-BMSC Spheroids Enhance Bone Repair Associated with H-Type Vessels and Immunomodulation.\nAbstract: The therapeutic potential of bone marrow mesenchymal stem cells (BMSCs) in bone tissue engineering (BTE) is compromised by functional decline during conventional two-dimensional (2D) expansion. We hypothesized that chitosan film-based three-dimensional (3D) culture rejuvenates BMSC potency, synergistically promoting angiogenesis and immunomodulation for vascularized bone regeneration. Mouse BMSCs were cultured into spheroids on chitosan films. Their stemness, proliferation, migration, senescence, osteogenic, and proangiogenic potential were compared with 2D cultures. Paracrine effects were evaluated by treating human umbilical vein endothelial cells (HUVECs) and RAW264.7 macrophages with BMSC-conditioned medium (CM). In vivo, gelatin methacryloyl (GelMA) hydrogel-encapsulated 3D-BMSC spheroids were implanted into mouse critical-size cranial defects. Compared to 2D counterparts, 3D-BMSCs exhibited increased stemness, proliferation, migration, delayed senescence, osteogenic differentiation, and enhanced proangiogenic potential. We observed that conditioned medium from 3D-BMSCs (3D-CM) was associated with in vitro angiogenesis and orchestrated a proreparative microenvironment by promoting M2 macrophage polarization and suppressing M1 inflammation. In vivo, GelMA + 3D-BMSC spheroids achieved greater bone regeneration, which was accompanied by a proreparative immune microenvironment and enhanced CD31/EMCN-positive H-type-like vessel formation. This chitosan film-based 3D culture system effectively augments BMSC therapeutic potency, simultaneously enhancing intrinsic cell properties and orchestrating a proregenerative microenvironment, thereby offering a promising experimental platform for critical-sized bone defect repair.\n\nID: 42563592\nTitle: Waist-to-Body Mass Index Ratio and Risk of Musculoskeletal Disease in Type 2 Diabetes: A Cohort and PhIP-Seq Analysis.\nAbstract: Musculoskeletal complications in type 2 diabetes (T2DM) are inadequately captured by body mass index (BMI). Waist-to-BMI ratio (WBR) may better reflect adverse body composition. We examined cross-sectional and longitudinal associations between WBR and musculoskeletal disorders in T2DM. This two-phase study was conducted within an ongoing hospital-based cohort at the First Affiliated Hospital of Fujian Medical University (Fuzhou, China). The cross-sectional analysis included 4157 adults with T2DM recruited between March 2012 and August 2023 (54.3% men; mean age 59.4\u2009\u00b1\u200910.3\u2009years), using data from their first assessment. Associations of waist circumference (WC), waist-to-height ratio (WHtR), waist-to-hip ratio (WHR), BMI and WBR with osteopenia, sarcopenia, sarcopenic osteopenia (SOs), sarcopenic obesity (SOb) and fractures were evaluated. The prospective cohort comprised a longitudinal subset enrolled between March 2012 and June 2022, ensuring at least 1\u2009year of follow-up prior to administrative censoring in August 2023. A total of 440 individuals (57.0% men; mean age 59.7\u2009\u00b1\u20099.7\u2009years) were followed for a median of 34.0\u2009months (20.0-57.0). Associations between time-dependent WBR and incident outcomes were assessed using Cox models. A nested exploratory analysis was conducted within the cohort. Thirty participants with extreme annualised WBR change (\u0394WBR/yr) were selected. Baseline serum samples collected at enrolment, prior to outcome occurrence, were analysed using phage immunoprecipitation sequencing (PhIP-Seq). Cross-sectionally, WBR was negatively correlated with bone mineral density and appendicular skeletal muscle mass index and positively correlated with osteopenia, sarcopenia, SOs, SOb and fractures (all p\u2009<\u20090.01), whereas BMI, WC, WHtR and WHR showed weaker associations. After adjustment, higher WBR was independently associated with osteopenia (men: OR 1.723, 95% CI 1.614-1.840; women: OR 1.420, 1.348-1.495), sarcopenia (men: OR 4.779, 4.165-5.484; women: OR 2.991, 2.683-3.334), SOs (men: OR 6.261, 5.314-7.377; women: OR 4.336, 3.753-5.010), SOb (men: OR 4.737, 3.975-5.646; women: OR 4.652, 3.715-5.825) and fractures (men: OR 1.236, 1.093-1.397; women: OR 1.103, 1.003-1.213; all p\u2009<\u20090.05). Prospectively, higher time-dependent WBR predicted incident osteopenia (HR 1.365, 95% CI 1.024-1.820), sarcopenia (HR 1.282, 1.086-1.512), SOs (HR 1.408, 1.176-1.686), SOb (HR 1.634, 1.262-2.116) and fractures (HR 1.369, 1.029-1.821). PhIP-Seq analysis identified differential autoantibody reactivity related to muscle structural organisation and cytoskeletal regulation, while bone-related differences were enriched in Wnt signalling and hormone-related pathways. Higher WBR and longitudinal increases were independently associated with osteopenia, sarcopenia, sarcopenic phenotypes and fractures in individuals with T2DM.\n\nID: 42563490\nTitle: SLC7A5 promotes colorectal cancer liver metastasis by reprogramming tryptophan metabolism through the Kyn/XANA\u2012AhR axis and reshaping the immune microenvironment.\nAbstract: Colorectal cancer (CRC) is a leading cause of cancer-related death and is associated with high recurrence rates. Solute carrier family 7 member 5 (SLC7A5), a core transporter that facilitates the transmembrane movement of tryptophan, plays a role in various cancers. However, whether and how SLC7A5 promotes colorectal liver metastasis (CRLM) through tryptophan metabolism reprogramming and immune remodelling remain unexplored. We integrated public datasets and clinical specimens to analyse SLC7A5 expression and prognosis, and validated its role in proliferation and metastasis using in vitro assays and in vivo models. Targeted metabolomics and isotope tracing identified kynurenine (Kyn) and xanthurenic acid (XANA) as downstream metabolites of SLC7A5. Single-cell RNA sequencing (scRNA-seq) and conditioned medium experiments were used to assess the impact of SLC7A5 on the tumour immune microenvironment (TIME). SLC7A5 expression increases sequentially in normal tissue, primary tumours and liver metastases, and higher SLC7A5 levels are associated with worse prognosis. SLC7A5 facilitates CRC cell growth, metastasis and epithelial\u2012mesenchymal transition (EMT) by promoting the production of Kyn and XANA and subsequent activation of the aryl hydrocarbon receptor (AhR). scRNA-seq analysis and conditioned medium experiments demonstrated that SLC7A5 knockdown reprograms the TIME by driving macrophages towards an antigen-presenting phenotype, alleviating CD8+ T-cell exhaustion, polarising CD4+ T cells towards Th1/Th17 subsets and triggering antigen-driven immunoglobulin G (IgG)-secreting B-cell clonal expansion, effects that were reversed by exogenous Kyn/XANA supplementation. Moreover, combination therapy with the SLC7A5 inhibitor JPH203 and anti-programmed cell death protein 1 (PD-1) antibody produced synergistic tumour growth inhibition and heightened antitumour immune responses. Collectively, our findings reveal that SLC7A5 drives CRLM through tryptophan/Kyn/XANA-AhR signalling and concomitant remodelling of the TIME, positioning SLC7A5 as a promising target for combination therapy with anti-PD-1 in CRLM.\n\nID: 42563243\nTitle: Microtubules in Spinal Cord Injury: From Cytoskeletal Dysregulation to Therapeutic Regeneration.\nAbstract: Spinal cord injury (SCI) triggers an immediate and sustained disruption of the composition and organization of the neuronal cytoskeleton. Radical alterations in axonal and dendritic microtubules characterize both the acute injury phase and the protracted recovery period. For decades, researchers have sought to correct these microtubule defects as a therapeutic strategy to encourage axonal regeneration, collateral sprouting, and the functional rewiring of neuronal circuits. Recent studies have demonstrated that taxol and related microtubule-active drugs improve outcomes in rodent models. These benefits are achieved by preventing microtubule depolymerization, stabilizing existing polymers, and promoting new assembly within both afflicted neurons and the glial cells essential for repair. While these findings highlight the therapeutic potential of microtubule-based interventions, we posit that successful clinical translation necessitates a more sophisticated approach rooted in the growing knowledge of microtubule-related proteins and their intricate regulatory mechanisms. This review evaluates progress in this arena, specifically examining the microtubule interactome network that includes structural microtubule-associated proteins (MAPs) such as Tau, MAP1A, MAP1B, MAP2, and MAP6, as well as the stathmin family, plus-end tracking proteins, and microtubule-severing proteins such as fidgetin and spastin. In addition, we analyze the contribution of molecular motor proteins and regulatory MAPs, including CRMP2 and CRMP4, as well as upstream transcription factors governing their expression. Finally, we address convergent regulation through kinases such as GSK3\u03b2 and CDK5, which represent a central mechanistic axis linking injury signaling to cytoskeletal failure. By integrating data from studies on development and regeneration into a unified mechanistic model, we provide a framework for microtubule-based therapeutics for SCI.\n\nID: 42562998\nTitle: Bletilla striata polysaccharide inhibits osteoclast differentiation by suppressing macrophage glycolysis and MMP9 expression.\nAbstract: Utilizing single-cell RNA sequencing and network pharmacology, this study explored the mechanism by which Bletilla striata polysaccharide (BSP) mitigates peri-implantitis-associated osteolysis. Integrated analyses revealed a significant expansion of pro-inflammatory macrophages and osteoclasts in diseased tissues, with differentially expressed genes enriched in glycolytic pathways. Mechanistic exploration indicated that BSP suppresses osteoclastogenesis primarily by targeting matrix metalloproteinase-9 (MMP9), thereby inhibiting proteolytic activity and cytoskeletal remodeling. Preliminary rescue experiments supported this notion, showing that while BSP effectively downregulated LPS-induced MMP9 upregulation and suppressed macrophage glycolytic metabolism, forced overexpression of MMP9 partially restored MMP9 levels and reversed the inhibitory effect of BSP on osteoclast formation. These findings suggest a potential \"metabolism-protease\" interplay, where BSP concurrently modulates immune metabolism and protease activity to alleviate inflammatory bone loss, providing a foundational basis for developing plant-derived polysaccharide therapeutics.\n\nID: 42562953\nTitle: Targeted Modulation of Lipid Mediator-Biosynthetic Enzymes as Strategy for Inflammation Resolution Pharmacology.\nAbstract: Lipid mediators (LMs) comprise a large variety of signaling molecules that are enzymatically produced from polyunsaturated fatty acids (PUFA) in a wide biosynthetic network. These pivotal mediators regulate all stages of inflammation, from initiation, progression, and maintenance to resolution and regain of tissue homeostasis. While leukotrienes and prostaglandins, produced from arachidonic acid (AA) by the 5-lipoxygenase (LOX) and cyclooxygenase (COX) pathways, respectively, mediate/promote inflammatory reactions and related symptoms, the specialized pro-resolving mediators (SPMs) terminate and resolve inflammation. SPMs encompass mainly the omega-3-PUFA-derived resolvins, protectins, and maresins, which are synthesized by sequential PUFA oxygenation steps, involving primarily 15-LOX-1/2 isoforms, but for some specific SPMs, also the 5-LOX, 12-LOX, COX-2, and cytochrome P450 enzymes mediate one of these oxygenations. Due to their valuable inflammation-resolving features, different strategies have been developed in order to exploit the beneficial functions of SPMs for the intervention with chronic inflammatory diseases. Here, we review the promising strategy of promoting endogenous SPM formation by applying exogenous agents that activate SPM-biosynthetic enzymes, also in combination with omega-3-PUFA supplementation, for resolution pharmacology. Results from pilot clinical trials that confirm the applicability and efficacy of such agents and their combinations in patients suffering from chronic inflammatory disorders are briefly discussed.\n\nID: 42562889\nTitle: Engineered macrophages with IL-10-TLR9 signal switch receptors for reprogramming tumor microenvironment and enhancing antitumor immunity.\nAbstract: Chimeric antigen receptor (CAR) T cell immunotherapy has achieved remarkable success in hematologic malignancies, prompting the exploration of CAR strategies in solid tumors. Here, we developed a CAR-like signal-switching receptor-macrophage (SR CAR-M) that recognizes IL-10, a major immunosuppressive cytokine enriched in solid tumors, and converts this inhibitory signal into a pro-inflammatory activation through the Toll-like receptor 9 (TLR9) intracellular signaling pathway. SR CAR-Ms effectively blocked IL-10-mediated STAT3 phosphorylation while activating TLR9 downstream signaling, including nuclear translocation of nuclear factor-\u03baB and upregulation of IRF1, thereby adopting an M1-like phenotype with enhanced phagocytic capacity and tumor cytotoxicity. Domain-deletion controls demonstrated that both IL-10 binding and TLR9 signaling are indispensable. In addition, SR CAR-Ms promoted dendritic cell maturation, enhanced T cell proliferation and effector function, and prevented T cell exhaustion. In an orthotopic 4T1 breast cancer model, infused SR CAR-Ms selectively accumulated in tumors, depleted local IL-10 while inducing inflammatory cytokine production, suppressed tumor growth, and prolonged survival without systemic toxicity. The signal-switching mechanism was validated in primary bone marrow-derived macrophages and human monocyte-derived macrophages, supporting the translational applicability. Further enhancement was achieved by engineering dual-function SRP\u03b1 CAR-Ms secreting anti-PD-L1 antibodies, which outperformed either SR CAR-M or anti-PD-L1 monotherapy. The SR CAR-M platform transforms an immunosuppressive cytokine into a location-specific activation trigger, simultaneously depleting the inhibitory signal and remodeling the tumor microenvironment. This signal-switching paradigm offers a versatile approach for treating solid malignancies that are resistant to conventional immunotherapies.\n\nID: 42562887\nTitle: Metabolic-epigenetic crosstalk in innate immune cell plasticity within the tumor microenvironment.\nAbstract: The tumor microenvironment exerts profound metabolic and epigenetic pressures that shape the plasticity of innate immune cells, influencing their capacity to promote or suppress tumor progression. Emerging evidence highlights the intricate interplay between metabolic reprogramming and epigenetic modifications in macrophages, neutrophils, and other innate immune populations within the tumor microenvironment. Tumor-derived metabolites, hypoxia, and nutrient availability dynamically regulate chromatin accessibility, histone modifications, and DNA methylation patterns, thereby driving context-dependent immune phenotypes. Notably, metabolic rewiring can imprint long-lasting epigenetic changes, a phenomenon known as innate immune memory, which alters subsequent immune responses. Here, we discuss how key metabolic pathways, including glycolysis, fatty acid oxidation, and amino acid metabolism, govern innate immune cell fate and function via epigenetic mechanisms. We also highlight recent advances in epigenomic profiling that have unveiled distinct chromatin landscapes associated with innate immune dysfunction across cancer types. Finally, we explore emerging therapeutic strategies that target the metabolic-epigenetic axis to restore innate immune surveillance and enhance immunotherapy efficacy. A deeper understanding of this metabolic-epigenetic crosstalk could reveal novel avenues for modulating innate immunity in cancer therapy.\n\nID: 42562774\nTitle: Mitochondrial alterations in pellagra-associated central chromatolysis: Comparison with ballooned achromatic neurons of other etiologies.\nAbstract: Neuronal central chromatolysis (CC) is the histopathological hallmark of pellagra encephalopathy, a neurological deficit resulting from vitamin deficiencies. Pellagrous CC neurons are morphologically similar to ballooned achromatic neurons in other conditions but the distinct pathomechanisms remain unclear. We performed a clinico-neuropathological analysis of 10 autopsy cases of pellagra encephalopathy. The pellagra encephalopathy cases were immunohistochemically compared with disease controls, including cases of axonal injury and neurodegenerative diseases. Electron microscopic evaluation and immunohistochemical examinations targeting mitochondrial fragmentation were performed for a representative case. Four of 10 pellagra encephalopathy patients exhibited prolonged impairment of consciousness distinguishable from alcohol withdrawal delirium. Pellagrous CC neurons were negative for cytoskeletal markers whereas ballooned achromatic neurons in the disease control cases were positive. Immunohistochemical analysis of mitochondrial markers revealed that CC neurons exhibited more intense immunoreactivity for COX-IV and mitochondrial fissure factor compared to the disease controls. Transmission electron microscopy of these CC neurons revealed a marked increase in the mitochondria with amorphous densities. These findings indicate that the pathomechanism of pellagrous CC is distinct from that of the ballooned achromatic neurons of other etiologies. Mitochondrial alterations in pellagrous CC neurons suggest that neuronal energy deficits resulting from nicotinamide adenine dinucleotide deficiency induce mitochondrial fragmentation.\n\nID: 42562723\nTitle: Bilirubin reductase regulates macrophage senescence and modulates implant-associated Staphylococcus aureus osteomyelitis.\nAbstract: Osteomyelitis (OM) remains difficult to diagnose early due to its heterogeneous pathology and reliance on invasive biopsy. This study aimed to identify reliable diagnostic biomarkers and explore their roles in macrophage senescence during OM pathogenesis. We integrated single-cell RNA sequencing, bulk transcriptomics, and senescence-related gene sets to identify key genes. A diagnostic model was constructed using 3 machine-learning algorithms. Mendelian randomization analysis was applied to infer causality. Biliverdin Reductase A (BLVRA)'s role in macrophage senescence was validated through in vitro and in vivo Staphylococcus aureus infection models. Seven diagnostic biomarkers were identified, with a combined model showing high accuracy (area under the curve? > 0.96). Mendelian randomization analysis confirmed a causal effect of BLVRA on OM risk. Single-cell data revealed predominant BLVRA expression in macrophages. Experimental validation showed that Staphylococcus aureus infection upregulates BLVRA and promotes macrophage senescence. BLVRA is a causal mediator of OM linked to macrophage senescence. This multi-omics approach offers a basis for early diagnosis and suggests potential immunotherapeutic targets for OM.\n\nID: 42562574\nTitle: Mitotic MAX bookmarking drives MYC-dependent hypertranscription at TBP-bound promoters.\nAbstract: Faithful genome reactivation after mitosis is essential for cell identity, yet the mechanisms driving global postmitotic transcription remain unclear. Here, we show that the MYC oncogene and its obligate partner MAX drive a postmitotic hypertranscriptional state in mouse embryonic stem cells. Cell cycle-resolved single-cell RNA-seq in inducible Max -/- cells reveals that early G1 hypertranscription is strongly impaired without MAX. Mechanistically, MAX remains bound to thousands of promoters during mitosis, while MYC is largely excluded. Using high-temporal-resolution profiling, pharmacological inhibition of MYC/MAX, and acute MAX degradation at mitotic exit, we demonstrate that MAX mitotic binding triggers rapid MYC recruitment and transcriptional amplification of TBP-bound promoters by enhancing RNA polymerase II occupancy and efficient initiation and elongation. These findings redefine MYC/MAX as master regulators of gene regulatory inheritance across mitosis.\n\nID: 42562332\nTitle: 2'-O-Galloylhyperin attenuates osteoclastogenesis and estrogen-deficiency osteoporosis by targeting MLK3-mediated NF-\u03baB signaling.\nAbstract: Estrogen deficiency-induced osteoporosis is largely driven by excessive osteoclast formation and bone resorption, but the direct pharmacological targets of flavonoid derivatives in osteoclast differentiation remain unclear. Here, we investigated the anti-osteoclastogenic activity and molecular mechanism of 2'-O-Galloylhyperin (2'-O-GH), a structurally defined flavonoid derivative. The effects of 2'-O-GH on RANKL-induced osteoclastogenesis were evaluated in bone marrow-derived macrophages and RAW264.7 cells using TRAP staining, qPCR, western blotting, F-actin staining, immunofluorescence, and bone resorption assays. Target identification was performed using a biotinylated 2'-O-GH probe coupled with pull-down and LC-MS/MS analysis, followed by molecular docking and microscale thermophoresis. In vivo efficacy was assessed in an ovariectomy-induced osteoporosis mouse model. 2'-O-GH inhibited RANKL-induced formation of TRAP-positive multinucleated osteoclasts without evident cytotoxicity at effective concentrations. It downregulated osteoclast-related markers, including NFATc1, c-FOS, SRC, ACP5, ATP6V0D2, and CTSK, and impaired F-actin ring formation and bone resorption. Mechanistically, 2'-O-GH restrained RANKL-induced NF-\u03baB p65 nuclear translocation. Chemical proteomics identified MAP3K11/MLK3 as a candidate target, and molecular docking and microscale thermophoresis supported its direct interaction with 2'-O-GH. 2'-O-GH further suppressed RANKL-induced phosphorylation of MLK3 and IKK\u03b1/\u03b2, whereas MLK3 overexpression partially rescued NF-\u03baB activation and osteoclast differentiation. In ovariectomized mice, 2'-O-GH attenuated bone loss without obvious effects on body or uterine weight. These findings identify MLK3 as a pharmacological target of 2'-O-GH and suggest that 2'-O-GH suppresses osteoclastogenesis through the MLK3/IKK/NF-\u03baB axis.\n\nID: 42564504\nTitle: Adverse exposure burden, NMR metabolomics, and risk of incident abdominal aortic aneurysm.\nAbstract: The cumulative impact of multidomain adverse exposures on abdominal aortic aneurysm (AAA) risk and the underlying metabolic pathways remain insufficiently understood. We analyzed 304,482 UK Biobank participants free of aortic aneurysm at baseline. Twenty-six exposures were grouped into five domains to derive domain specific and overall exposure scores. Associations with incident AAA were assessed using Cox models. To explore potential metabolic pathways, we applied a two stage NMR metabolomics framework combining multivariable linear regression, metabolite specific Cox models, and a 10-fold cross validated elastic net Cox model to generate a metabolite score. Mediation analyses and XGBoost models were also performed. During a mean follow up of 14.9 years, 1,671 participants developed AAA. A higher overall exposure score was associated with an increased risk of incident AAA (per SD increase: HR, 1.08; 95% CI, 1.07-1.11). Among domain specific scores, the socioeconomic, social psychology, and lifestyle scores were independently associated with AAA, whereas the environmental pollution and living environment scores were not. Current smoking showed the strongest association among individual exposures (HR, 7.95; 95% CI, 6.81-9.27). Overall exposure burden was associated with broad metabolomic perturbations, and a 13-metabolite score was significantly associated with AAA (per SD increase: HR, 1.38; 95% CI, 1.35-1.41), mediating 5.78% of this association. Adding exposure and metabolite scores improved prediction beyond clinical factors alone. Greater multidomain adverse exposure burden was associated with higher incident AAA risk, partly through metabolic signatures related to inflammation and lipoprotein metabolism, and may provide incremental value for AAA risk stratification.\n\nID: 42564168\nTitle: Gut microbiota-derived metabolites in cardiovascular disease: mechanisms, disease-specific roles, and translational opportunities.\nAbstract: Cardiovascular disease remains the leading cause of global morbidity and mortality and arises from complex interactions among metabolic dysregulation, inflammation, thrombosis, and vascular dysfunction. In recent years, the gut microbiota has emerged as an important regulator of cardiovascular pathophysiology, largely through the production of bioactive metabolites that act on distant organs. This review summarizes the major classes of gut microbiota-derived metabolites involved in cardiovascular disease, with particular emphasis on trimethylamine N-oxide, short-chain fatty acids, phenylacetylglutamine, bile acids, and tryptophan-derived metabolites. We discuss how these metabolites influence endothelial dysfunction, immune activation, lipid handling, platelet reactivity, cardiac remodeling, gut barrier integrity, and blood pressure regulation through interconnected signaling pathways. We further examine their disease-specific relevance in atherosclerosis, heart failure, hypertension, and coronary artery disease/acute coronary syndrome. In addition, we evaluate current translational strategies targeting microbial metabolism, including dietary modulation, probiotics and prebiotics, fecal microbiota transplantation, and selective inhibition of microbial enzymes. Rather than viewing individual metabolites as uniformly harmful or protective, we propose that cardiovascular risk is better understood as the net consequence of interacting microbial metabolic pathways within specific host contexts. This metabolite-centered framework may help refine biomarker development, risk stratification, and pathway-guided interventions in cardiovascular medicine.\n\nID: 42564117\nTitle: Effects of immunosuppression on tracheal mucosal responses after infection with Mycoplasma gallisepticum in vaccinated and unvaccinated chickens.\nAbstract: Vaccination is the most common method used to control infection caused by Mycoplasma gallisepticum in chickens. However, concurrent immunosuppression may compromise vaccine efficacy. This study investigated the effect of immunosuppression induced by either chicken anaemia virus (CAV) or infectious bursal disease virus (IBDV), administered prior to or following vaccination with the M. gallisepticum live vaccine strain ts-304 (Vaxsafe MG304), on tracheal host responses to subsequent challenge with virulent M. gallisepticum. Tracheal responses were assessed by genome-wide transcriptional profiling in these groups and compared across unvaccinated-unchallenged, unvaccinated-challenged, vaccinated-unchallenged and vaccinated-challenged groups that had not been exposed to CAV or IBDV. Immunosuppression resulted in significant differences in tracheal transcriptional responses compared to immunocompetent groups, irrespective of the timing of infection with CAV or IBDV. Differences in transcription were more pronounced in the IBDV-infected groups than the CAV-infected groups. Functional interrogation of differentially transcribed genes revealed adverse effects of M. gallisepticum on extracellular and intracellular signalling, cell communication, cellular actin dynamics, formation of the cellular cytoskeleton, and cellular metabolic pathways in the tracheal mucosa of immunosuppressed groups. In addition, there were indications of down-regulation of both innate and adaptive immune responses, including cytokine signalling, antigen processing presentation, and immune cell receptor signalling in the immunosuppressed groups. Specifically, findings indicated that infection with CAV impaired pro-inflammatory and adaptive T-cell responses in the tracheal mucosa. The findings implied that the primary immune response induced post-vaccination and the secondary immune response induced post-challenge with virulent M. gallisepticum were both affected by infection with these two viruses. Coupled with previous observations of reduced antibody titres against M. gallisepticum, and increased rates of recovery of virulent M. gallisepticum in both CAV- and IBDV-infected groups, the significant transcriptional changes detected in the current study highlighted the roles of both cell-mediated (CMI) and humoral immunity (HI) in vaccine-induced protection, as CAV mainly affects CMI and IBDV mainly affects HI. These findings will assist in identifying the mechanisms underlying the reduced efficacy of live attenuated mycoplasma vaccines in immunosuppressed animals.\n\nID: 42564050\nTitle: Metabolomics-based analysis of the effects of different storage temperatures on the post-harvest quality of truffles.\nAbstract: To investigate the effects and mechanisms of different low-temperature storage conditions on the postharvest quality of truffles. This study used truffles from Huidong County, Sichuan Province as the research subject, setting four storage temperatures: -4\u00a0\u00b0C, 0\u00a0\u00b0C, 4\u00a0\u00b0C, and 20\u00a0\u00b0C. Physiological indicators such as postharvest decay rate, relative electrical conductivity, and respiration rate were measured. These were combined with metabolomic analysis to screen for differential metabolites and metabolic pathways. The results showed that truffles stored at -4\u00a0\u00b0C have a relatively low rot rate and are better suited for storage(P\u00a0<\u00a00.05). However, the relative electrical conductivity and MDA content of truffles stored at -4\u00a0\u00b0C were significantly higher than those in the 0\u00a0\u00b0C and 4\u00a0\u00b0C treatment groups (P\u00a0<\u00a00.05). The SDH activity of truffles stored at 0\u00a0\u00b0C and 4\u00a0\u00b0C was significantly higher than that of the -4\u00a0\u00b0C group in the later stages (P\u00a0<\u00a00.05). CAT activity was significantly higher in the -4\u00a0\u00b0C group than in the other groups during the first 21 days of storage(P\u00a0<\u00a00.05). Metabolomic analysis revealed that the -4 \u00b0C vs 4 \u00b0C group had the most differential metabolites in the positive ion mode, with pathways such as branched-chain amino acid metabolism, glutathione metabolism, and steroid biosynthesis being significantly enriched (P\u00a0<\u00a00.05). This study systematically reveals the effects of storage temperature on truffle preservation and its mechanisms, providing a theoretical basis for postharvest preservation of truffles.\n\nID: 42563993\nTitle: Metabolic reprogramming orchestrates microglial fate in cerebral ischemia-reperfusion injury: a spatiotemporal immunometabolic perspective.\nAbstract: Cerebral ischemia-reperfusion injury (CIRI) represents a critical pathological cascade that paradoxically exacerbates neurological damage following revascularization therapy for acute ischemic stroke (AIS). The pathogenesis of CIRI is intricately linked to dysregulated neuroinflammation, with microglia-the resident innate immune cells of the central nervous system-serving as central orchestrators of this response. Emerging evidence indicates that microglia undergo profound metabolic reprogramming encompassing glucose metabolism, the tricarboxylic acid (TCA) cycle, fatty acid metabolism, and NAD+ homeostasis, which fundamentally dictates their functional polarization and consequent neuroinflammatory outcomes. Rather than existing as discrete pro-inflammatory versus reparative phenotypes (classically referred to as M1/M2), microglia exhibit a continuum of activation states with distinct metabolic signatures that evolve dynamically across spatiotemporal dimensions following CIRI. Here, we systematically synthesize current knowledge on the core molecular mechanisms underlying microglial metabolic reprogramming, including the ACOD1/itaconate pathway, the glycolysis-OxPhos balance, and NAMPT-mediated NAD+ homeostasis. We critically examine the intricate crosstalk between these metabolic pathways and neuroinflammatory signaling cascades, revealing how metabolic checkpoints serve as integrative nodes that decode microenvironmental cues into functional outputs. Building on this mechanistic foundation, we evaluate emerging intervention strategies targeting metabolic reprogramming, stratified by intervention modality and translational readiness, with emphasis on agents in active clinical development. Finally, we identify prevailing challenges-including spatiotemporal heterogeneity, cell-specific targeting requirements, and clinical translation barriers-and outline future directions integrating single-cell omics, systems biology approaches, and advanced delivery systems. This comprehensive analysis aims to provide a refined conceptual framework and highlight promising therapeutic avenues for mitigating CIRI through strategic modulation of microglial immunometabolism.\n\nID: 42563598\nTitle: Global research landscape on the brain-gut axis in early life: a bibliometric and visualized study.\nAbstract: the brain-gut axis was recognized as a bidirectional communication system linking the central and enteric nervous systems through neural, hormonal, immune, and metabolic pathways. It played a pivotal role in early-life neurodevelopment, immune programming, and gastrointestinal function. Although the field had grown rapidly, a comprehensive bibliometric evaluation of global research trends, hotspots, and collaborations was lacking. we conducted a bibliometric and visualized analysis of publications on the brain-gut axis in early life from 2004 to 2024, using the Web of Science Core Collection (WoSCC) database. CiteSpace was used to generate co-authorship, institutional collaboration, keyword co-occurrence, and co-citation networks, as well as burst detection, timeline views, and dual-map overlays. a total of 1,429 publications were analyzed. Research output increased steadily from 2015 and peaked in 2023, reflecting growing global interest. The United States and China were the most productive countries, with strong collaborative ties observed among institutions in North America, Europe, and East Asia. University College Cork, University of California System, and Harvard University were the leading institutions, while J. F. Cryan, T. G. Dinan, and G. Clarke were the most influential authors. Early studies focused on anatomical and developmental aspects, while recent hotspots included autism spectrum disorder, intestinal permeability, fecal microbiota transplantation, and psychological stress. Mechanistic keywords highlighted short-chain fatty acids, tryptophan metabolism, vagus nerve signaling, and microglia-immune interactions. this study provided a comprehensive bibliometric overview of early-life brain-gut axis research over the past two decades. It revealed dynamic thematic evolution, expanding interdisciplinary collaboration, and the emergence of translational opportunities. These findings offer a valuable reference for future research directions in pediatric neurogastroenterology and microbiota-based interventions.\n\nID: 42563579\nTitle: Glucose-Independent Metabolic Signatures of SGLT2 Inhibition in Diabetic Kidney Disease: Integrated Insights from Mendelian Randomization and Transcriptomics.\nAbstract: Diabetic kidney disease (DKD) remains a major cause of terminal renal failure, with residual risk remaining unacceptably high despite standard glucose control. Although the sodium-glucose co-transporter 2 (SGLT2) inhibitors have proven reno-protective properties extending beyond that explained by glucose lowering alone, unique glucose-independent molecular mechanisms are still incompletely defined. Unveiling these non-glycemic metabolic pathways is of paramount importance for new therapeutic targets and optimized clinical management. A systematic multi-omics triangulation framework integrating Mendelian randomization (MR) with tissue-specific transcriptomics was conducted. Two-sample MR and multivariable Mendelian randomization (MVMR) adjusted for fasting blood glucose were leveraged as a screening tool to detect glucose-independent serum metabolites in humans using large-scale genome-wide association study data. These findings were validated with transcriptomic signatures from both diabetic and non-diabetic mouse kidney models to identify conserved core genes and convergent metabolic pathways. Genetically proxied SGLT2 inhibition associated with a reduced risk of DKD, with an odds ratio of 0.58, and improved renal function markers. MVMR highlighted 259 glucose-independent metabolites, covering systemic alterations in lipid and amino acid metabolism. A cross-model transcriptomic comparison revealed seven key genes functionally enriched in fatty acid oxidation and ketone body utilization. This convergence supports the concept of a fasting-like metabolic switch and coordinated downregulation of fibrosis-related extracellular matrix pathways irrespective of diabetic status. This study delineates a systemic-renal metabolic axis whereby SGLT2 inhibition drives renoprotection via metabolic reprogramming and anti-fibrotic mechanisms distinct from blood glucose lowering. These findings provide genetic evidence for specific non-glycemic targets and represent a novel mechanistic insight for precision therapeutic intervention in kidney disease.\n\nID: 42563547\nTitle: Selenium Alleviates Manganese Toxicity in 'Red Fuji' Apple: Insights From Combined Physiological and Transcriptomic Approaches.\nAbstract: Selenium (Se), a beneficial element, plays a pivotal role in mitigating plant stress, yet its potential in alleviating manganese (Mn) toxicity in apple trees remains poorly understood. This study explores the potential of Se in alleviating Mn-induced stress in Malus domestica Borkh. cv. Red Fuji, a cultivar known for its sensitivity to Mn. Through a combination of physiological analysis and transcriptomic profiling, we provide comprehensive insights into the mechanisms by which Se enhances Mn tolerance. The results demonstrated that selenite application balanced nutrient elements, stabilized the photosynthetic system, and reduced oxidative stress. Additionally, selenite promoted cell wall remodeling and modulated hormone levels. Transcriptome analysis further revealed that selenite regulated genes associated with polyunsaturated fatty acid hydrolase, sucrose hydrolase, and photosynthesis, indicating its role in alleviating Mn stress. GO and KEGG enrichment analyses highlighted that differentially expressed genes were enriched in pathways related to phenylpropanoid biosynthesis, alpha-linolenic acid metabolism, and galactose metabolism, suggesting key metabolic pathways involved in Mn stress responses. Weighted gene co-expression network analysis (WGCNA) identified core module genes strongly correlated with antioxidant enzymes and substances, chlorophyll content, and mineral element concentrations. In conclusion, Se effectively mitigates Mn stress in 'Fuji' apples through multi-level regulatory mechanisms, providing a theoretical foundation for the application of Se-enriched agriculture in apple cultivation.\n\nID: 42563441\nTitle: Phenolic-Rich Lentil Extracts Regulate Cytokine Production, Metabolic Pathways and Barrier Function in Intestinal Epithelial Cells.\nAbstract: Phenolic compounds are recognized for antioxidant, anti-inflammatory, and antidiabetic properties. Lentils are abundant in these compounds, yet comparative studies across varieties and intestinal cells effects remain limited. This study evaluated the nutritional composition, phenolic profile, antioxidant activity, and \u03b1-glucosidase inhibition of four lentil types in raw and cooked forms. L01 had the highest bioactive potential and was the only one selected for further evaluation in Caco-2 cells under basal and IL-1\u03b2-stimulated conditions. Cooking altered composition, leading to higher protein, fiber, and carbohydrates, reducing tannins, and maintaining high phytic acid in some varieties. L01 consistently showed the highest phenolic content, antioxidant activity, and enzyme inhibition. Its phenolic profile was dominated by kaempferol derivatives, (epi)catechin, and procyanidins, with cooking increasing monomeric catechins but reducing procyanidin oligomers. At noncytotoxic levels, L01 extracts reduced IL-6/8 secretion in stimulated cells, with stronger effects from raw extracts. Additionally, they decreased expression of inflammatory markers (IL-6/8/1\u03b2) while increasing expression of metabolic regulation- and barrier-related genes (Peroxisome proliferator-activated receptor-\u03b3, Sirtuin 1, Occludin, and Cadherin-1). Only raw extracts significantly enhanced Heme oxygenase-1 expression under stimulation. These findings highlight compositional differences beyond tegument color and support further investigation of phenolic-rich lentils as potential functional food ingredients targeting gut and metabolic health.\n\nID: 42563426\nTitle: Colonic metabolomic and transcriptomic alterations in a mouse model of metabolic syndrome.\nAbstract: Metabolic syndrome (MetS), characterized by abdominal obesity, insulin resistance, dyslipidemia, and hypertension, affects a substantial proportion of the global population and increases the risk for cardiovascular disease, diabetes, and metabolic dysfunction-associated steatotic liver disease (MASLD). Despite its prevalence, there are currently no effective pharmacological therapies targeting MetS, highlighting the need to identify novel etiological mechanisms, particularly within the gastrointestinal (GI) tract. Using a mouse model of MetS and healthy lean controls, we assessed the colonic microenvironment through metabolomic, transcriptomic, and microbiome analyses. Colonic organoids were cultured to further explore epithelial alterations. Additionally, human MetS fecal metabolomics data were cross-compared with the mouse model to validate translational relevance. MetS mice exhibited upregulation of colonic anabolic pathways, including glycolysis, the pentose phosphate pathway, and the tryptophan/kynurenine pathway, without evidence of intestinal inflammation. Microbiome analysis revealed an increased abundance of the genus Lactobacillus in MS NASH mice. Colonic organoids from MetS mice showed altered goblet cell differentiation. Comparative analysis with human MetS fecal metabolomics demonstrated similar dysregulated pathways, underscoring the translational relevance of these findings. Our study reveals significant metabolic and microbial alterations in the colon of MS NASH mice, implicating a dysfunctional GI tract as a potential etiological factor in MetS. These findings highlight specific metabolic pathways and microbial signatures that could serve as future therapeutic targets for MetS.\n\nID: 42562877\nTitle: Spectral biophysical cytometry with nanosensors reveals remodelling of immune cells in atherosclerosis.\nAbstract: The biophysical properties of cells determine cellular physiology. Leveraging these properties for biomedical applications demands the ability to measure multiple parameters simultaneously across millions of cells and diverse cell types. However, current technologies are limited by throughput and low dimensionality. Here we introduce spectral biophysical cytometry (SBC), a high-throughput platform that integrates environment-sensitive nanosensors with spectral flow cytometry to resolve multiparametric biophysical properties of immune cells at single-cell resolution. By using fluorescent nanosensors that report membrane order, mitochondrial potential and membrane potential, SBC enables simultaneous quantification of key cellular physical states across diverse immune cell populations. When applied to peripheral blood mononuclear cells, SBC reveals cell-type-specific biophysical heterogeneity and identifies distinct remodelling signatures associated with atherosclerosis. In particular, T-cell subsets exhibit substantial alterations in membrane order and mitochondrial depolarization, reflecting coordinated changes in lipid composition and metabolic pathways. Integration with lipidomics and transcriptomics demonstrates that the nanosensors can detect biophysical shifts that correlate with dysregulated lipid metabolism and mitochondrial function, providing mechanistic insight into immune dysfunction in disease. Importantly, SBC achieves rapid, label-efficient profiling using commercially available instrumentation, enabling scalable biomarker discovery directly from blood samples and establishing a powerful strategy for linking biophysical phenotypes to immune cell function.\n\nID: 42562534\nTitle: A novel L-\u03b2-Galactoglucan alleviates physical fatigue by modulating load-specific metabolic pathways via the gut-muscle Axis.\nAbstract: Prolonged physical fatigue impairs physiological homeostasis and quality of life, necessitating effective interventions. This study aimed to investigate the anti-fatigue effects and underlying mechanisms of a novel L-\u03b2-galactoglucan (APG) with two distinct molecular weights in mice under two different swimming load models using multiomics approaches. The results showed that APG could significantly extend exhaustive swimming time, reduce elevated serum lactate and blood urea nitrogen levels, increase muscle glycogen storage, and mitigate swimming-induced skeletal muscle and mitochondrial damage. Compared with its medium-molecular-weight counterpart, high-molecular-weight APG was more effective at improving these indicators. APG optimized the gut microbiota and increased the content of short-chain fatty acids. Specifically, it increased the ratio of Bacteroidetes/Bacillota and promoted the abundance of beneficial bacteria, including Dubosiella, Lachnospiraceae_UCG-006, Parabacteroides, Roseburia, Faecalibaculum and norank_o_Clostridia_vadinBB60_group, while increasing the concentrations of acetic, propanoic, and isobutyric acids. Notably, APG exerted load-specific regulatory effects: In the weight-bearing model, APG modulated mainly purine metabolism, whereas in the non-weight-bearing model, it predominantly regulated tryptophan metabolism. Both pathways converge to synergistically activate AMPK/SIRT1/PGC-1\u03b1 signaling. Molecular docking further verified that APG exhibited strong binding affinity to key targets in these pathways. Collectively, these findings demonstrate that APG exerts anti-fatigue effects in a molecular weight-dependent and load-specific manner via the gut-muscle axis, providing a scientific basis for the development of APG as a targeted anti-fatigue functional ingredient.\n\nID: 42562516\nTitle: Unveiling the metabolic signatures of kratom use in humans via NMR-based blood plasma metabolomics.\nAbstract: Consumption of herbal-based beverages can alter metabolite profiles, reflecting metabolic changes related to their potential health effects. Kratom is traditionally consumed in Southeast Asia as a decoction to treat various ailments. In recent years, kratom has gained substantial popularity in Western countries for a range of off-label uses, however, reports of its adverse effects, including fatalities, have raised safety concerns. Because changes in metabolite profiles can indicate alterations in health status, metabolomics provides a valuable tool for assessing the potential benefits and risks of kratom. Although animal studies suggest that kratom influences metabolic pathways and behavior, human data remain limited. Therefore, this study aimed to characterize changes in blood plasma metabolites and associated metabolic pathways in regular kratom users using an NMR-based metabolomics approach. Blood plasma samples were collected from 37 regular kratom users and 12 control subjects (non-users), and analyzed using NMR spectroscopy. Multivariate analysis revealed a clear separation between the two groups, indicating distinct plasma metabolite profiles. A total of 17 metabolites were identified as different between the two groups based on 1H CPMG, JRES and HSQC spectra. Among these, glycine, formate, dimethylamine and N-methyltyramine were significantly increased, whereas pyruvate, \u029f-pyroglutamic acid and citrate were significantly reduced in kratom users compared with non-users. Metabolite enrichment and pathway analyses revealed perturbations in glycine, serine, and threonine metabolism; pyruvate metabolism; glyoxylate and dicarboxylate metabolism; citrate cycle; glycolysis or gluconeogenesis; and glutathione metabolism in kratom users. The biological relevance of these metabolites and pathways is discussed. Overall, these findings provide a better understanding of the metabolic alterations associated with long term kratom consumption in humans.\n\nID: 42562481\nTitle: Understanding phage dynamics and their potential roles during soy sauce fermentation using metagenome-assembled genomes.\nAbstract: The composition and functional roles of phages in fermented foods have been gaining increasing attention. However, their ecological functions and underlying mechanisms in high-salt soy sauce fermentation remain largely unexplored. In this study, we investigated phage communities, their potential functions, phage-host interactions, and host defense mechanisms in two different soy sauce fermentation processes (Cantonese-type process, CP; Japanese-type process, JP) using shotgun metagenomics. A total of 823 phage species (viral operational taxonomic units, vOTUs) were identified, with the majority exhibiting a temperate lifestyle (89.19%). The most abundant family was Straboviridae (CP, 9.95%-11.39%; JP, 12.04%-13.73%), followed by Salasmaviridae (CP, 6.92%-7.94%; JP, 5.70%-7.02%). Although the phage composition differed between the two processes, the number of vOTUs was positively correlated with prokaryotic species richness, total acidity, and amino acid nitrogen content, and negatively correlated with pH. A comparative genomic analysis revealed that 91 phages were associated with 26 bacterial genomes (metagenome-assembled genomes, MAGs), with Lactococcus petauri (MAG16) and Halomonas elongata (MAG51) hosting the most phage species. An analysis of host defense mechanisms showed that all 45 bacterial MAGs harbored CRISPR-Cas type I systems, and 95.6% encoded restriction-modification systems. Functional annotation using the KEGG and CAZymes databases indicated that the phages predominantly encoded genes related to cell growth, replication, and metabolism of amino acids, carbohydrates, and nucleotides, with more genes enriched in the JP than in the CP. Additionally, auxiliary metabolic genes (e.g., pfkA, ldh, adhP, ilvE, and arcA) were identified in 29 phages. These genes are potentially involved in metabolic pathways that may be linked to flavor compound production. Together, these findings provide novel insights into the ecological and potential functional roles of phages during soy sauce fermentation.\n\nID: 42562465\nTitle: Process-driven flavour modulation in soybean-based alternative proteins via Neurospora crassa coculture fermentation.\nAbstract: Soybean-derived ingredients are widely utilised in plant-based foods and protein formulations but are often limited by lipid-derived off-flavours, particularly undesirable \"beany\" and \"green\" notes. Microbial fermentation offers a clean-label strategy to improve flavour while maintaining processing sustainability. In this study, a factorial experimental design was applied to optimise solid-state fermentation of soybeans using two distinct coculture systems: a fungal-fungal system (Neurospora crassa-Rhizopus oryzae), and a fungal-bacterial system (Neurospora crassa-Lactiplantibacillus plantarum). Fermentation temperature (25-30\u00a0\u00b0C), inoculum ratio (1,1,2,1,1,2), and duration (3-5\u00a0days) were evaluated to determine their effects on microbial dynamics, metabolite formation, aroma profiles, and sensory perception. Fermentation significantly reduced beany odorants, with hexanal levels decreasing by up to 95% compared with the uninoculated control. The two coculture systems exhibited distinct flavour regulation pathways. The fungal-bacterial system (N. crassa-L. plantarum) followed a carbohydrate-driven pathway characterised by controlled acidification and selective proteolysis, promoting enrichment of umami-related metabolites, including glutamic acid (up to 1.55\u00a0mg/g), umami-active peptides and nucleotides (guanosine monophosphate and inosine monophosphate), and moderated lactic acid production (<6.5\u00a0g/L). In contrast, the fungal-fungal system (N. crassa-R. oryzae) followed a lipid-driven pathway characterised by enhanced lipolysis and mobilisation of polyunsaturated fatty acids, leading to increased formation of lipid-derived volatiles such as 2,4-decadienal associated with fatty and savoury aromas. These contrasting metabolic pathways were supported by multivariate analysis, confirming distinct taste- and aroma-driven optimisation profiles, demonstrating that flavour development is strongly parameter-dependent. These findings establish a framework for fermentation-enabled flavour engineering in soybean-based alternative proteins.\n\nID: 42562152\nTitle: TRIB3 promotes lipid accumulation and lipogenesis in esophageal cancer progression.\nAbstract: Esophageal cancer is a malignant tumor with extremely poor prognosis. Its developmental mechanisms remain incompletely elucidated. Altered lipogenesis plays a crucial role in tumor progression. However, the specific mechanisms by which TRIB3 regulates lipid accumulation in esophageal cancer remain unclear. This study aims to investigate how TRIB3-ATF4 interaction influences lipogenic enzyme expression and tumor progression through the ERK1/2 pathway in esophageal cancer. This study employed the esophageal cancer cell lines (TE5 and KYSE150) as a research model. We performed TRIB3 overexpression, knockdown, and ATF4 interaction analyses. These were combined with molecular biology techniques and functional assays (EdU, colony formation, migration, and invasion). Pharmacological inhibitors of ERK and FASN, alongside oleic acid (OA) rescue, validated the signaling and metabolic pathways. TRIB3 regulates fatty acid metabolism. TRIB3 knockdown suppresses fatty acid biosynthesis, cell growth, and migration. Mechanistically, TRIB3 interacts with ATF4 to activate the MEK/ERK pathway. FASN inhibition reverses TRIB3's oncogenic effects. Conversely, OA rescues the tumor-suppressive phenotypes of TRIB3 knockdown. Inhibition of the MEK/ERK pathway attenuates TRIB3-mediated lipid metabolism and progression. This study identifies TRIB3 as a key metabolic regulator in esophageal cancer. It links stress adaptation to lipogenic reprogramming. Targeting this metabolic vulnerability represents a promising therapeutic strategy.\n\nID: 42561592\nTitle: Ambient fine particulate matter components and liver fat and stiffness in youth: metabolic vulnerability in PNPLA3 risk carriers.\nAbstract: Exposure to fine particulate matter (PM2.5) is linked to metabolic dysfunction-associated steatotic liver disease (MASLD), yet responsible chemical constituents and the biological basis of susceptibility remain unclear, limiting source-targeted regulation and precision prevention in vulnerable populations. We examined PM2.5 components - liver outcomes associations in youth, assessed susceptibility by PNPLA3 genotype (the strongest known MASLD genetic determinant), and evaluated genotype-specific metabolic mediation in two independent cohorts. Baseline data from 113 Los Angeles Latino adolescents with obesity (discovery cohort) were analyzed, including magnetic resonance imaging-measured hepatic fat fraction (HFF), liver stiffness (LS), and serum metabolomics and lipidomics. Visit-year average exposures to 15 PM2.5 components were estimated from residential addresses. Linear regression and g-computation assessed individual component and mixture effects, with PNPLA3 genotype as modifier. Moderated mediation analyses identified metabolic mediators, followed by pathway enrichment and total mediation effect estimation. Findings were replicated in 81 young adults of mixed race/ethnicity and body mass index (replication cohort) using level 1 metabolites confirmed by authentic standards. PM2.5 components and mixture were predominantly positively associated with HFF and LS; simultaneous interquartile range increases in all components were associated with 10.0% higher HFF. Elemental carbon (EC), bromine (Br), copper, potassium, and lead were key contributors. Stronger effects were observed in PNPLA3 GG carriers. GG carriers exhibited more mediating metabolite features (n\u00a0=\u00a0550 vs. 196), with broader pathway enrichment in carbohydrate, lipid, and amino acid metabolism, and signaling/endocrine pathways. Significant total mediation effects were observed exclusively in GG carriers. Replication confirmed GG-specific associations of EC, Br with HFF, and identified increased fatty acid 16:1, and decreased guanidinosuccinate, proline as candidate mediators. PM2.5 components potentially indicative of combustion and traffic sources (i.e. EC, Br) increase MASLD risk in youth via metabolic pathways, with genotype-specific responses likely heightening susceptibility in PNPLA3 GG carriers.\n\nID: 42561511\nTitle: Intrabody B1 targeting TDP-43 modulates neuroinflammatory and metabolic pathways in a preclinical ALS model.\nAbstract: TDP-43 pathology is a hallmark of Amyotrophic Lateral Sclerosis (ALS), yet no therapeutic strategy effectively targets its upstream molecular consequences. Here, we investigated whether the anti-TDP-43 intrabody scFv B1 modulates neuroinflammatory and metabolic pathways in a preclinical ALS model, and whether these effects translate into functional benefit after symptom onset. Using phage display, we previously identified single-chain variable fragments (scFvs) binding TDP-43, including the candidate therapeutic scFv B1. In NSC-34 motor neuron-like cells overexpressing human wildtype TDP-43, B1 reduced NF-\u03baB activation, consistent with disruption of TDP-43-driven inflammatory signaling. For in vivo assessment, B1 was delivered via AAV-CAP.B10 after symptom onset in the hTDP-43(WTxA315T) transgenic mouse model, enabling neuro-specific expression. Two cohorts were analyzed - longitudinal (nine months) and terminal (six months post-treatment) - through behavioral testing, PET imaging, metabolomics, transcriptomics, and plasma biomarker analyses. B1 achieved robust CNS expression and modulated several disease-relevant molecular pathways. RNA-sequencing revealed attenuation of NF-\u03baB-related inflammatory signatures and partial normalization of metabolic and trophic gene expression. Metabolomic profiling identified shifts toward wild-type-like levels in oxidative stress, mitochondrial, and membrane phospholipid metabolites. Despite these molecular effects, symptomatic B1 administration did not improve motor behavior or reduce plasma neurofilament light chain (NfL) concentrations. Notably, plasma TDP-43 levels were stabilized, indicating systemic target engagement. Collectively, scFv B1 modulates upstream pathogenic processes associated with TDP-43 proteinopathy but is insufficient to reverse established neurodegeneration after symptom onset, underscoring the need for earlier and likely combinatorial intervention strategies in ALS.\n\nID: 42561463\nTitle: Carvacrol potentiates gentamicin against Staphylococcus aureus via disrupting bacterial respiratory bioenergetics.\nAbstract: The emergence of methicillin-resistant Staphylococcus aureus (MRSA) calls for novel antibiotic adjuvants. Carvacrol (Car), a natural monoterpene phenol derived from the essential oils of aromatic plants, exhibits membrane-active properties and has potential as an antibacterial adjuvant. Here, we found that Car markedly enhanced the bactericidal activities of Gentamicin (Gen) against MRSA. Mechanistically, Car dissipated membrane potential, inhibited respiratory chain dehydrogenase activity, and depleted intracellular ATP. Moreover, Car promoted membrane lipid peroxidation, ultimately leading to structural and functional membrane damage and bacterial death. Notably, pharmacological perturbation of respiratory and metabolic pathways further supported that this synergistic effect depends on bacterial respiratory bioenergetics. In addition, the combination showed favorable in vivo antibacterial efficacy in both Galleria mellonella and murine infection models, without apparent toxicity under the tested conditions. Collectively, these findings indicate that Car may serve as a natural antibacterial adjuvant for combination therapy against drug-resistant infections.\n\nID: 42561449\nTitle: Beyond phenylalanine to tyrosine: Mapping the comprehensive phenylalanine hydroxylase (PAH) pathway for systems biology.\nAbstract: The phenylalanine hydroxylase (PAH) pathway is an enzymatic pathway focused primarily on the hydroxylation of the amino acid L-phenylalanine (Phe) to L-tyrosine (Tyr). However, the functioning of this pathway can also have significant impacts on other downstream metabolites. In addition, both common and rare genetic variants have been demonstrated to significantly impair PAH pathway function. However, to our knowledge, the comprehensive PAH pathway including influences on related downstream metabolic pathways has not been mapped in an integrative manner. As such, we conducted a narrative review of the literature to describe the comprehensive PAH pathway, including influences on downstream related metabolic pathways, while mapping a visual depiction of these integrative processes. In addition to the hydroxylation of Phe to Tyr, the comprehensive pathway narrative describes Phe metabolism and transport across the blood brain barrier including competition with other large neutral amino acids, Tyr catabolism, and others. Discussion of the importance of these metabolic processes in the context of PAH genetic variation are also provided. With an increased focus on conducting health research from a systems biology perspective, this work is critical to improving our understanding of the downstream effects of amino acid metabolism and their possible impacts on health outcomes.\n\nID: 42560997\nTitle: Guazuma ulmifolia butanol extract protects against cadmium-induced hepatotoxicity via HO-1/Sirt-1 activation, miRNA-lncRNA modulation, and metabolic reprogramming.\nAbstract: Guazuma ulmifolia is traditionally used for liver disorders, but its protective mechanisms against heavy metal toxicity are poorly defined. This study evaluated the phytochemical profile and hepatoprotective mechanisms of G. ulmifolia butanol extract (Gul-BuOH) against cadmium-induced liver injury. Gul-BuOH was chemically profiled by UPLC-PDA-ESI-qTOF-MS/MS. Cadmium hepatotoxicity was induced in rats, followed by Gul-BuOH treatment (100 and 200 mg/kg). Liver injury, oxidative stress, inflammation, gene expression (Let-7a, HOTAIR), histopathology, HO-1/Sirt-1 immunoreactivity, and serum metabolomic changes were assessed. Chemical profiling led to the annotation of 42 compounds, including mainly flavonoids and phenolic acids, highlighting the rich phytochemical composition of G. ulmifolia. CdCl2 exposure increased hepatic Cd accumulation and elevated ALT, AST, and ALP, reduced TAC, and increased NO and MDA. Gul-BuOH significantly reduced hepatic Cd levels by 2.6- and 3.2-fold, restored TAC by 38.3% and 83.2%, and decreased NO (56.3% and 63.4%) and MDA (45.4% and 54.6%) at 100 and 200 mg/kg, respectively. Inflammatory markers NF-\u03baB-p and TNF-\u03b1 were markedly suppressed, while miRNA Let-7a was upregulated and lncRNA HOTAIR was downregulated. Histological and immunohistochemical analyses revealed near-complete restoration of hepatic architecture and normalization of HO-1 and Sirt-1 expression at the high dose. Serum metabolomics' OPLS-DA model performance indicators demonstrated strong reliability, with an R2Y (explained variance) of 0.991 and a Q2 (predictive variance) of 0.988). The model identified 36 significantly altered metabolites that were largely normalized by Gul-BuOH, implicating linoleic acid metabolism, amino acid biosynthesis, and ascorbate-related pathways. Gul-BuOH affords dose-dependent protection against Cd-induced liver injury by modulating oxidative stress, inflammation, metal detoxification, and metabolic pathways, supporting the traditional use of G. ulmifolia and its potential as a multi-target hepatoprotective agent.\n\nID: 42560163\nTitle: Antifungal mechanism of eudesmane sesquiterpenoid glycosides from the fruits of Pittosporum kweichowense against Sclerotinia sclerotiorum.\nAbstract: Sclerotinia stem rot (SSR), caused by Sclerotinia sclerotiorum (Lib.) de Bary, is among the most destructive crop diseases worldwide. This study aimed to identify novel antifungal agents from Pittosporum kweichowense and elucidate their mechanisms against this pathogen. Six eudesmane-type sesquiterpenoid glycoside esters (ESGEs) were isolated from the fruit of P.\u2009kweichowense, including four new compounds pitkweifrucosides A-D (1-4), and two known analogs (5-6). Their structures were established by spectroscopic analyses and comparison with authentic samples. Compound 5 (Pitsubcoside H, PS-H) showed potent antifungal activity against S.\u2009sclerotiorum with a median effective concentration of 38.61\u2009\u03bcg\u2009mL-1. At 100\u2009\u03bcg\u2009mL-1, PS-H inhibited mycelial growth and reduced sclerotial formation by 75.00%. It also delayed sclerotial germination at early stages and decreased oxalic acid production by 73.08%. TEM observation confirmed disruption of cellular integrity. Transcriptomic and metabolomic analyses further revealed that PS-H exerts antifungal effects primarily through perturbation of amino acid metabolism and ribosomal function. This study demonstrates that PS-H exhibits significant antifungal activity against S.\u2009sclerotiorum via disruption of key metabolic pathways. These findings provide a solid basis for developing this compound as a sustainable, low-toxicity alternative to conventional fungicides. \u00a9 2026 Society of Chemical Industry.\n\nID: 42560142\nTitle: Single-Cell Transcriptional States of Human Leukocyte Antigen DR Positive CD4 Positive T Cells Linked to Genetic Susceptibility of Gastric Cancer.\nAbstract: Gastric cancer (GC) involves complex immune-metabolic crosstalk, but MR-prioritized immunophenotypes and mediating metabolites remain unclear. Two-sample Mendelian randomization (MR) was performed using GWAS summary data for 731 immunophenotypes, 1,400 circulating metabolites, and GC (218,792 European participants). Instruments were selected at p\u2009<\u20091\u2009\u00d7\u200910-5, LD-clumped (r2\u2009<\u20090.001, 10,000 kb), and filtered for strength (F\u2009>\u200910). IVW served as the primary estimator, with sensitivity and reverse MR analyses. Two-step MR explored metabolite-mediated pathways. Single-cell RNA-seq from 56 samples across three sources was integrated to resolve HLA-DR+ CD4+ T-cell transcriptional states, evaluate GC genetic-risk enrichment via scDRS, and infer cell-cell communication using CellChat. Twenty-six immunophenotypes showed candidate associations with GC. HLA-DR expression on HLA-DR+ CD4+ T cells was inversely associated with GC risk (OR\u2009=\u20090.761, 95% CI 0.634-0.912, FDR q\u2009=\u20090.0393). Reverse MR was not FDR-significant, and MR-Egger indicated no directional pleiotropy. Candidate mediation involved bilirubin degradation product C17H18N2O4(2). Single-cell analysis identified five HLA-DR+ CD4+ T-cell subsets; T1 and T5 showed relatively higher GC genetic-susceptibility enrichment, with T5 exhibiting low CytoTRACE scores. These subsets were linked to immune activation and chemokine signaling. The exploratory TIGIT-NECTIN2 signal was not robustly retained after CellChat sensitivity filtering. This study suggests a potential inverse association between HLA-DR+ CD4+ T-cell immunophenotypes and GC risk, with bilirubin-related metabolites as a candidate mediating pathway. Subsets T1/T5 provide candidate directions for future GC immune-prevention research. 1. This study identifies a suggestive inverse association between HLA\u2011DR+ CD4+ T-cell-related immunophenotypes and gastric cancer risk.2. This study identifies bilirubin metabolite C17H18N2O4(2) as a candidate mediator in the HLA-DR-GC association pathway.3. This study reveals two HLA\u2011DR+ CD4+ T subsets (T1/T5) with relatively higher GC genetic-susceptibility enrichment.4. This study evaluates TIGIT-NECTIN2 as an exploratory checkpoint-related communication signal that was not robustly retained after CellChat sensitivity filtering.5. This study provides candidate directions for evaluating specific T cell subsets and metabolic pathways in GC prevention research.\n\nID: 42564737\nTitle: Report on the 13th international workshop on the CCN family of genes and inaugural ARBIOCOM conference, Nice, France.\nAbstract: The 13th International Workshop on the CCN Family of Genes, held in Nice as part of the inaugural ARBIOCOM World Conference, brought together investigators with diverse research backgrounds, disciplines, and expertise. Building on the long-standing mission of the International CCN Society and the expanding ARBIOCOM initiative, the meeting highlighted the growing importance of interdisciplinary exchange in accelerating discovery in normal and pathological signaling networks. Scientific sessions featured presentations by renowned speakers and early-career investigators alike, creating a highly collaborative environment that fostered discussion of emerging concepts and translational opportunities. Among the major themes, this joint conference-meeting highlighted \"hot\" research topics such as the nuclear and extracellular roles of CCN proteins in regulating gene expression, tissue development and remodeling, stem cell differentiation and therapies, and disease initiation and progression. Presentations on skeletal biology emphasized how extracellular matrix proteins and matricellular factors shape bone, cartilage, and connective tissue development and pathology, whereas vascular sessions revealed new mechanistic links between extracellular cues, endothelial remodeling, macrophage-driven vessel regression and vascular smooth muscle homeostasis. Other talks extended the relevance of new signaling molecules in intestinal regeneration, hepatic inflammation, metabolic control, and cancer progression, illustrating the broad biological reach of these pathways. The meeting also emphasized the value of integrating new model systems, advanced single-cell approaches, and functional in vivo studies to uncover mechanisms that were previously unknown. Collectively, the scientific sessions and discussions identified and filled key knowledge gaps and generated new hypotheses with strong potential for future discoveries. By connecting established expertise with complementary scientific perspectives, this meeting provided a fertile platform for cross-pollination of ideas and highlighted several avenues for future research aimed at developing novel diagnostic and therapeutic strategies and tools.\n\nID: 42564657\nTitle: Erratum to \"TREM2 Deficiency Regulates Macrophage Apoptosis and Repair in Radiation-Induced Skin Injury\".\nAbstract: [This corrects the article DOI: 10.34133/research.1018.].\n\nID: 42564509\nTitle: High expression of USP15 affects tumor progression and immune infiltration in hepatocellular carcinoma.\nAbstract: Ubiquitin-specific protease 15 (USP15) is closely associated with the occurrence and progression of hepatocellular carcinoma (HCC). However, its role in shaping the immune landscape of HCC remains unclear. The expression levels, proportions, and spatial distributions of USP15 and specific immune cell subsets in HCC tissues were evaluated using multiplex immunohistochemistry (mIHC). In the tumor parenchyma of HCC tissues, the infiltration of immune cells, particularly natural killer (NK) cells, was significantly reduced (p<0.05). Further analyses revealed that USP15 expression levels were significantly associated with clinical stage and other clinicopathological parameters (p<0.05). In particular, NK cell infiltration was significantly correlated with N stage, M stage, and overall tumor-node-metastasis (TNM) stage (p<0.05). USP15 contributes to the establishment of an immunosuppressive tumor microenvironment in HCC by inhibiting T cell and NK cell infiltration, facilitating programmed death-ligand 1 (PD-L1)-mediated immune evasion, and enhancing macrophage recruitment. These findings indicate that USP15 may serve as a potential therapeutic target for HCC.\n\nID: 42564443\nTitle: A low-dose immunotherapy targeting Fc gamma Receptors and heparan sulfate proteoglycan to impact myeloid cells and control cancers with diverse immunosuppressive profiles.\nAbstract: Myeloid cells play a key role in cancer-associated immunosuppression because their accumulation and reprogramming inhibit antitumor responses and support tumor growth. To modulate their activity, we targeted Fc\u03b3 receptors (Fc\u03b3Rs), which are broadly expressed in myeloid subsets. Since low-affinity Fc\u03b3 receptor IIb (Fc\u03b3RIIb) mediates inhibitory signaling, we designed an immunotherapy active at a low dose to limit binding to Fc\u03b3RIIb while retaining interaction with higher-affinity Fc\u03b3Rs. We engineered an Fc-based fusion protein, whose activity is potentiated by its ability to engage both Fc\u03b3Rs and a coreceptor, Heparan Sulfate Proteoglycan (HSPGs). This immunotherapy, named Fc-T54, combines an HSPG-ligand, named T54, with human IgG1-Fc. Compared with Fc, Fc-T54 displayed superior binding to Fc\u03b3 receptor IIa (Fc\u03b3RIIa), Fc\u03b3 receptor IIIa (Fc\u03b3RIIIa) and enhanced interactions with human leukocytes, including neutrophils, B-lymphocytes, as well as with monocytes, and dendritic cells (DCs) within peripheral blood mononuclear cells. Functionally, Fc-T54 increased monocyte/macrophage and B-cell numbers, reduced neutrophil abundance, and boosted DC activation in both the human and murine systems. Subcutaneous administration of low-dose Fc-T54 - or its murine surrogate - inhibits tumor growth in immune-deserted and immune-excluded mouse models and synergizes with anti-PD-1 therapy in an immune-inflamed model. Tumor microenvironment analysis in the bladder cancer model revealed that the immunotherapy decreased the proportion of granulocytic myeloid-derived suppressor cells while increasing CD8+ T cells and natural killer cells, promoting a microenvironment more prone to tumor control. This Fc\u03b3R/HSPG-engaging immunotherapy, administered subcutaneously, offers a novel approach to modulate the myeloid compartment and improve outcomes for ICI-resistant, deserted/excluded tumors, and for inflamed tumors when used in combination regimens.\n\nID: 42564178\nTitle: Metabolic immune checkpoints in cancer: how tumor-derived metabolites shape immunotherapy resistance.\nAbstract: Immune checkpoint blockade has transformed cancer therapy, yet many tumors remain intrinsically resistant or acquire resistance after initial response. Increasing evidence indicates that this failure is not determined solely by PD-1, PD-L1, CTLA-4, or T-cell exhaustion, but also by metabolically suppressive states within the tumor microenvironment. Tumor-derived metabolites can function as metabolic immune checkpoints by limiting effector immune activity, promoting regulatory or myeloid suppressive compartments, and weakening immunotherapy efficacy. This mini review summarizes recent experimental evidence showing how lactate, adenosine, tryptophan-derived metabolites, and nucleotide-derived metabolites shape immune escape and resistance to immune checkpoint blockade. Lactate links tumor glycolysis to Treg recruitment, impaired T-cell function, and lactylation-associated therapeutic resistance. The CD73-adenosine axis suppresses CD8+ T cells and natural killer cells while reinforcing regulatory and myeloid immune programs. Tryptophan-derived metabolites extend beyond the classical IDO1-kynurenine-AhR pathway to involve non-classical checkpoints such as Siglec-15 and broader kynurenine/indole/serotonin networks. Emerging evidence further identifies nucleotide-derived UDP signaling as a driver of macrophage-mediated immunosuppression. Finally, we discuss how targeting metabolic checkpoints in combination with immune checkpoint blockade may improve therapeutic responses. Defining the spatial and cellular contexts of metabolite-mediated immune suppression may enable more precise strategies to overcome immunotherapy resistance.\n\nID: 42564158\nTitle: Natural polysaccharides as immunometabolic modulators in metabolic diseases: mechanisms and translational challenges.\nAbstract: Metabolic disorders, especially obesity, type 2 diabetes mellitus, and metabolic dysfunction-associated steatotic liver disease, are becoming increasingly prevalent and have imposed a growing burden on public health systems. These diseases are commonly associated with insulin resistance and abnormal lipid metabolism, and increasing evidence indicates that immune imbalance and chronic low-grade inflammation are involved in their development. Natural polysaccharides are important bioactive components derived from plants, fungi, algae, and other natural sources. Current evidence supporting their beneficial effects in metabolic diseases is predominantly preclinical, mainly from cell-based and animal studies, while clinical evidence remains limited and heterogeneous. Natural polysaccharides have attracted interest as candidate bioactive compounds because some preparations have shown immunomodulatory and metabolic regulatory activities in experimental models. Their activities are closely related to structural features, including monosaccharide composition, glycosidic linkage types, molecular weight, branching structure, and chemical modification. Current preclinical evidence suggests that natural polysaccharides may alleviate metabolic inflammation by regulating macrophage polarization, suppressing pro-inflammatory cytokine production, modulating MAPK, NF-\u03baB, AMPK, and related signaling pathways, and reshaping the gut microbiota-immune axis. These compounds may help improve several pathological features of metabolic disorders, such as insulin resistance, abnormal lipid metabolism, inflammatory injury, and tissue dysfunction. However, several challenges still limit their translation, including unclear structure-activity relationships, inconsistent preparation standards, limited bioavailability, and insufficient well-designed clinical trials. Therefore, this review provides an overview of the natural sources, structural properties, immunomodulatory actions, and therapeutic prospects of natural polysaccharides in metabolic diseases, with a focus on their involvement in immune regulation and metabolic inflammation.\n\nID: 42563994\nTitle: Axonal pathfinding during the development of the nervous system.\nAbstract: Guidance of axons sprouting from maturing neuroblasts, during intermediate trajectories and in seeking target neurons for synaptogenesis, is a fundamental developmental process in central nervous system\u00a0maturation. Axons but not dendrites sprout from neuroblasts during migration. The growth cone of the axonal tip projects constantly changing multiple veils and spikes (lamellipodia and filopodia) that contain microtubules, actin microfilaments, mitochondria, endosomes, and membrane receptor proteins. They are sensitive to changes in ionic calcium flux and may be impeded by perinatal hyper- or hypoglycemia. The growth of axonal membranes occurs mainly at the growth cone. Neurofilaments appear in the axonal tip as it approaches its target. Growth cones are attracted to or repelled by various extracellular matrix molecules that guide them, such as netrins and glycoproteins. Numerous genes are involved, some specific for only certain projections. Neurotransmitters later to be secreted are recognized in growing axons before their synthesis. Axonal fascicles are enveloped by extracellular keratan sulfate that ensures that fascicles contain axons of similar origin and destination and whose neurons secrete the same transmitter. Near their targets, axonal tips may ramify to form synapses on more than one neuron. Transitory pioneer axons provide supplementary mechanical guides to permanent axonal trajectories. Thalamus and olfactory bulb contain axonless neurons with dendrodendritic synapses. Chromaffin neurons of neural crest origin develop no neurites. Most cerebral malformations involve aberrant axonal pathfinding; in holoprosencephaly, keratan sulfate abnormally ensheathes individual axons. Axonal pathfinding to near or distant target neurons is primordial for synaptic circuitry subserving normal and abnormal neurological functions including epilepsy.\n\nID: 42563679\nTitle: [Correlation analysis of macrophage migration inhibitory factor with related markers of septic myocardial injury and its prognostic predictive value].\nAbstract: To explore the association between macrophage migration inhibitory factor (MIF) and sepsis-induced myocardial injury (SIMI), as well as its predictive value for the prognosis of septic patients. A prospective observational study was conducted. Sixty-three adult patients with confirmed sepsis admitted to the department of critical care medicine of The First Affiliated Hospital of Xinjiang Medical University from July 2024 to June 2025 were consecutively enrolled. According to the cardiac troponin I (cTnI) level on the first day of admission, the patients were divided into SIMI group (cTnI\u22650.04 \u03bcg/L) and sepsis without myocardial injury group (cTnI<0.04 \u03bcg/L). The demographic data, admission-related scores, and laboratory indicators of septic patients, measured indicators such as MIF and interleukin-18 (IL-18) within 24 hours of patients' admission to the intensive care unit (ICU) were collected, and the indicators such as Acute Physiology And Chronic Health Evaluation II (APACHE II) score, Sequential Organ Failure Assessment (SOFA) score, oxygenation index, and echocardiographic indicators within 24 hours of patients' admission to the ICU were recorded. The clinical data of the two groups of patients were compared. The correlation between indicators was analyzed by using Pearson or Spearman rank correlation method. A receiver operator characteristic curve (ROC curve) was drawn to evaluate the predictive performance of MIF, IL-18, and their combination for 28-day death in septic patients. Multivariate Logistic regression analysis was used to screen independent risk factors for 28-day death in septic patients, and a nomogram model was constructed. The discrimination, calibration, and clinical utility of the model were evaluated using ROC curve, calibration curve, and decision curve analysis (DCA). A total of 63 septic patients were finally enrolled in the study, including 23 patients in the SIMI group and 40 patients in the non-SIMI group. The APACHE II score, alanine aminotransferase (ALT), aspartate aminotransferase (AST), N-terminal pro-brain natriuretic peptide (NT-proBNP), cTnI, MB isoenzyme of creatine kinase (CK-MB), IL-18, and MIF were all higher in the SIMI group compared to the non-SIMI group (all P<0.05). There were no statistically significant differences in demographic data, other laboratory indicators, and echocardiographic parameters between the two groups. Correlation analysis revealed a positive correlation between MIF and downstream inflammatory factor IL-18 and APACHE II score in septic patients (r values were 0.523 and 0.556, respectively, both P<0.05). Among echocardiographic indicators, MIF was negatively correlated with left ventricular ejection fraction (LVEF; r=-0.265, P<0.05), while there was no significant correlation between MIF and left ventricular posterior wall thickness at end-diastole or left atrial diameter at end-diastole (both P>0.05). ROC curve analysis revealed that both MIF and IL-18 possessed predictive value for 28-day death in septic patients [the area under the ROC curve (AUC) and 95% confidence interval (95%CI) were 0.745 (0.563-0.933) and 0.751 (0.614-0.892), respectively], and the combined prediction of the two had an AUC of 0.784 (95%CI was 0.629-0.940), with a sensitivity of 78.6% and a specificity of 79.6%. Multivariate Logistic regression analysis revealed that an elevated SOFA score [odds ratio (OR)=1.381, 95%CI was 1.067-1.787, P=0.014], increased IL-18 (OR=1.000, 95%CI was 1.000-1.001, P=0.023), elevated MIF (OR=1.000, 95%CI was 1.000-1.000, P=0.036), and decreased oxygenation index (OR=0.989, 95%CI was 0.978-1.000, P=0.046) were independent risk factors for 28-day death in patients with sepsis. Based on these variables, a nomogram model for predicting 28-day death in septic patients was constructed. ROC curve analysis indicated that the AUC of the nomogram model for predicting 28-day death in septic patients was 0.894 (95%CI was 0.766-1.000). Further analysis revealed that the model's C-index reached 0.894, and both the calibration curve and DCA curve suggested good discriminatory power, calibration capability and clinical utility of the model. MIF can serve as a sensitive biomarker for early identification of SIMI, and the combined detection of MIF and IL-18 can enhance the predictive efficacy of prognosis for sepsis patients.\n\nID: 42563516\nTitle: Novel labial adnexal sebaceous basaloid proliferation associated with sebaceous epitheliomas and adenocarcinomas in Labrador retrievers.\nAbstract: A distinctive peritumoral epithelial proliferation was identified exclusively in the labial region of Labrador retrievers in association with sebaceous neoplasms. To characterize this lesion, 515 sebaceous neoplasms diagnosed in dogs of different breeds between 2017 and 2025 were retrospectively reviewed. Among these, 2 of 255 epitheliomas (0.7%) and 22 of 41 adenocarcinomas (54%) arising in the lips exhibited a distinctive peripheral basaloid epithelial proliferation. The lesion was observed only in the lower lip of Labrador retrievers, occurring in association with either solitary or multifocal neoplastic nodules. No similar proliferations were identified after examining 103 labial lesions of other histotypes diagnosed in the same timeframe. Histologically, the proliferations consisted of 1- to 2-cell-thick epithelial cords surrounding pre-existing adnexal units. The cells showed minimal atypia and low mitotic activity. Immunohistochemically, they exhibited a cytokeratin (CK)5+/p63+/alpha-smooth muscle actin-/CK7- phenotype, supporting derivation from basal reserve cells of cutaneous glands and excluding differentiation toward mature apocrine epithelial or myoepithelial cells. The exclusive occurrence in Labrador retrievers suggests a possible breed-related predisposition. Although the biological behavior of this novel lesion is unknown, its recognition may be important in diagnostic pathology to avoid misinterpretation with an invasive adenocarcinoma.\n\nID: 42563511\nTitle: Early pre-symptomatic and sex-specific cardiac remodeling precedes heart failure in zebrafish with human actin mutation.\nAbstract: Dilated cardiomyopathy (DCM) is a leading cause of heart failure with notable sex differences in susceptibility and progression. Although sarcomere mutations such as cardiac actin ACTC1 p.T126I contribute to familial DCM, the in vivo effects and sex-specific consequences remain unclear. We generated a zebrafish model carrying the orthologous Acta1b p.T126I mutation and conducted longitudinal, sex-stratified analyses of cardiac function, morphology and gene expression. Mutants showed variable onset of cardiac dysfunction, with progressive DCM, pericardial effusion, ventricular dilation, and reduced survival in adults. Female mutants exhibited earlier and sustained diastolic dysfunction, greater cardiac remodeling and significantly lower survival compared to males, revealing pronounced sexual dimorphism. Molecular profiling at a pre-symptomatic stage identified upregulation of nppb, downregulation of hypertrophic transcription factors (gata4, mef2ca), and sex-specific alterations in calcium handling genes (serca2, pln1, slc8a1a) and proteostasis regulators (hsf1, bag3). Older stages demonstrated a variable shift of individuals' gene expression to cardiac remodeling and decompensation. These findings demonstrate that the Acta1b p.T126I mutation drives progressive, sex-specific DCM in zebrafish, highlighting biological sex as a critical modifier of sarcomeric cardiomyopathy progression and targeted therapy development.\n\nID: 42563266\nTitle: Nanomaterial Strategies for Pulmonary Delivery of Immunotherapeutics in Lung Cancer Treatment.\nAbstract: Organ-selective immunomodulation is increasingly viewed as a route to improve the therapeutic index of cancer immunotherapy, yet most agents are still delivered systemically, where limited tumor exposure and immune-related toxicities remain common. The lung is an attractive site for local intervention because it is directly accessible and immunologically specialized. However, effective pulmonary delivery is constrained by mucociliary clearance, airway mucus, alveolar macrophage uptake, and epithelial barriers. Nanomaterials can be rationally engineered to address these constraints, increasing pulmonary retention and concentrating immunotherapeutics within the lung tumor microenvironment while reducing systemic burden. This Review summarized the key physiological barriers for pulmonary immunotherapeutic delivery and discusses how nanomaterial properties shape deposition, retention, cellular partitioning, and downstream immune activation. We critically evaluate representative inhalable platforms across major immunotherapeutic modalities, including vaccines, immune checkpoint blockade, innate immune agonists (e.g., STING agonists), cytokine regulation, and emerging in situ immune-cell engineering strategies. We also highlight translational considerations. Together, these advances support inhalable immunotherapeutic nanomedicines as a complementary approach to current lung cancer treatment and a broader framework for pulmonary immune modulation.\n\nID: 42563250\nTitle: Late-onset external root resorption following periodontal regenerative therapy using rhFGF-2 and DBBM: A case report.\nAbstract: Periodontal regenerative therapy using recombinant human fibroblast growth factor-2 (rhFGF-2) combined with deproteinized bovine bone mineral (DBBM) has demonstrated favorable and predictable clinical outcomes for intrabony defects. However, long-term outcomes and potential challenges following such combination therapies remain poorly documented. A 40-year-old woman with generalized stage III grade C periodontitis underwent periodontal regenerative therapy using rhFGF-2 combined with DBBM for a one-wall defect at the mandibular left first molar (#19). Favorable periodontal healing was maintained for approximately 4 years. However, for tooth #19, the probing depth gradually increased at 5 years 2 months post-surgery, and the patient developed discomfort and pulpal symptoms by 6 years 2 months. Clinical examination revealed an agglomerate of DBBM particles and a palpable external root resorption lesion. The tooth was extracted due to irreversible pulpal involvement. This case illustrates that despite favorable early healing, periodontal regenerative therapy may lead to rare late-onset complications such as external root resorption. Long-term follow-up and careful consideration of biomaterial interactions are essential when employing combination regenerative approaches. Periodontal regenerative therapy using rhFGF-2 and DBBM achieved favorable clinical outcomes for 4 years before unexpected late-onset external root resorption developed. Long-term persistence and partial separation of DBBM particles, along with the response of macrophage- or osteoclast-lineage cells, are associated with a potential for delayed resorptive pathology on adjacent root surfaces. Clinicians should recognize the possibility of late complications and carefully consider biomaterial interactions when selecting regenerative strategies and informing patients. This case report describes a rare situation in which a molar initially healed well after periodontal regenerative therapy using rhFGF\u20102 and a bone substitute (DBBM), but developed external root resorption more than five years later. Although the treatment first reduced inflammation and improved tissue support, the long\u2010term presence of graft particles, together with complex cellular responses, may be linked to delayed changes on the root surface. This case highlights that even when early healing is successful, long\u2010term monitoring is essential, and clinicians should carefully consider how different regenerative materials may interact over time.\n\nID: 42562174\nTitle: Injection administration of passion fruit (Passiflora edulis) peel extract enhances physiological and immune responses in white shrimp Litopenaeus vannamei.\nAbstract: This study evaluated the immunostimulatory effects of passion fruit peel extract (PPE) in Litopenaeus vannamei through injection and its potential application as a functional feed additive. Shrimp were injected with different PPE dosages including 10 \u03bcg shrimp-1 PPE extract (PPE10), 20 \u03bcg shrimp-1 PPE extract (PPE20), and 40 \u03bcg shrimp-1 PPE extract (PPE40), and immune parameters were assessed, including total haemocyte count (THC), differential haemocyte counts, phenoloxidase (PO) activity, respiratory bursts (RBs) activity, phagocytic activity, clearance efficiency, and lysozyme activity. The results showed that PPE, particularly at the higher dose (PPE40), significantly enhanced THC, hyaline cells, and semigranular cells at later stages post-injection, while granular cells remained unchanged. PPE40 also significantly increased PO activity and RBs, indicating activation of the proPO system and oxidative defense. Additionally, phagocytic activity, clearance efficiency, and lysozyme activity were significantly elevated, demonstrating enhancement of both cellular and humoral immune responses. No significant differences in haemolymph glucose and lactate levels were observed among treatments, indicating that PPE did not induce physiological stress. The enhanced immune responses were further confirmed by a Vibrio alginolyticus challenge test, in which PPE40 exhibited significantly higher survival rates compared to other groups, demonstrating improved disease resistance.\n\nID: 42559550\nTitle: Nanoplastics Impair Neuroimmune Integrity Via Cellular Retention and Multiple Organelle Stress.\nAbstract: The biological persistence of nanoplastics (NPs) has raised growing concern regarding their potential to accumulate in human tissues yet their impact on neuroimmune cellular function remains largely undefined. Here, we investigated the neuroimmune effects of polystyrene NPs (100, 200, and 1000nm; 10 and 100\u03bcg/mL) across neuronal (SH-SY5Y, PCNs) and immune cells (THP1, macrophages). Cellular responses were assessed through analyses of cytotoxicity, immunocytochemistry and cytokine profiling. NPs exposure did not induce acute cytotoxicity but promoted persistent intracellular retention accompanied by lysosomal dysfunction, dysregulated autophagic flux, ER stress, and constrained mitochondrial function, thereby inducing a sublethal multi-organelle stress response. Macrophages exhibited greater vulnerability consistent with phagocytic burden, while inflammatory challenge further enhanced NPs uptake, reinforcing intracellular persistence. In contrast, neurons showed limited extracellular cytokine secretion yet accumulated intracellular IL-1\u03b2, suggesting low-grade inflammatory activation. Such responses were recapitulated in PCNs, supporting translational relevance across neuronal models. The cumulative nature of these observations suggests that NPs exposure may give rise to previously unrecognized accumulation-related pathologies, a phenomenon we term \"plasticoma\" as a conceptual framework, to describe the preferential deposition of non-degradable plastic particles within cells, to frame and stimulate future investigations into NP accumulation and pathology. These findings position NPs as potential determinant of neuroimmune dysfunction and highlight the importance of strategies aimed at mitigating their biological accumulation.\n\nID: 42559139\nTitle: Case Report: Prolonged nOPV2 shedding in an immunocompetent child from Tunisia border with Algeria, North African region.\nAbstract: Following the detection of vaccine-derived poliovirus type 2 (cVDPV2) in Algeria in 2022, enhanced surveillance activities along the Tunisian border identified novel Oral Poliovirus type 2 Vaccine (nOPV2) excretion in an apparently healthy nomadic child. Immunological investigations showed no evidence of major humoral, cellular, or phagocytic immune deficiency. To investigate the kinetics of viral shedding and characterize the complete genome of the isolated strain in this case report, longitudinal follow-up stool samples were collected and analyzed using cell culture inoculation, real-time RT-PCRs, and whole-genome sequencing. Virus was detected over a 76 to 126-days observation period. Assuming vaccination occurred in December 2022, the total duration of shedding may have extended up to approximately 138 to 188\u202fdays (4 to 7\u202fmonths) post-vaccination. Despite prolonged replication, the viruses showed limited within-host evolution and retained the major engineered attenuation features of nOPV2, with no evidence of domain V reversion, cre replacement, or recombination, and only limited VP1 divergence which allows its classification as nOPV2 category 8 strains. Our findings underscore the need to further investigate the potential for prolonged excretion and molecular evolution of nOPV2-like strains in immunocompetent individuals. Furthermore, targeted surveillance of high-risk and mobile populations, including migrants and nomadic communities, is essential to strengthen epidemiological security and support global poliovirus eradication initiatives.\n\nID: 42558044\nTitle: Macrophage PIM1 Drives Atherosclerosis by Enhancing Foam Cell Formation Via CD36.\nAbstract: Atherosclerosis is characterized by the buildup of fatty plaques that thicken and stiffen arterial walls. Macrophages (M\u03c6s) significantly contribute to this process through their scavenger receptor CD36. PIM1 is a serine/threonine kinase known to modulate immune responses and cell metabolism. However, its role in M\u03c6 lipid handling and atherogenesis is not well defined. This study examines the role of PIM1 in regulating CD36 expression and function in M\u03c6s during foam cell formation and atherosclerosis progression. We performed in vitro studies by treating murine peritoneal M\u03c6s from Pim1-/- and wild-type mice with oxLDL (oxidized low-density lipoprotein). We measured CD36, PIM1, and plaque-associated proteins and mRNA levels, oxLDL binding and uptake rates, and foam cell formation. For in vivo studies, we fed myeloid-specific Pim1-deficient (Apoe-/-Lyz2Cre/+Pim1fl/fl) and their littermate control (Apoe-/-Pim1fl/fl) mice a high-fat diet for 12 weeks. We then evaluated plaque formation in their aortic sinuses and arches. Deletion of Pim1 in M\u03c6s reduced CD36 protein expression by up to 96.7% compared with wild-type controls. This led to a 49.6% decrease in foam cell formation and a 25.5% reduction in cellular cholesterol after oxLDL treatment. Pharmacological inhibition of PIM kinase activity in wild-type M\u03c6s also impaired oxLDL handling, with a 64.5% reduction in binding and a 57.9% reduction in uptake. Bulk RNA-sequencing revealed that Pim1 deficiency downregulated PPAR\u03b3 (peroxisome proliferator-activated receptor gamma) signaling. Treatment with a PPAR\u03b3 agonist restored CD36 levels in the Pim1 knockdown M\u03c6s, suggesting that PIM1 regulates CD36 through PPAR\u03b3. Moreover, Pim1 myeloid-specific deficiency caused a 69.4% reduction in atherosclerotic plaque formation. PIM1 acts as a key upstream regulator of CD36 by enhancing PPAR\u03b3 activity in M\u03c6s. The PIM1-CD36 axis promotes oxLDL binding, uptake, and foam cell formation. Targeting the PIM1/PPAR\u03b3/CD36 pathway could offer new ways to modulate M\u03c6 lipid metabolism and reduce atherosclerotic plaque progression.\n\nID: 42556319\nTitle: When less is more and when it isn't: Microglial Spi1 and the limits of what we know.\nAbstract: Microglia are key players in Alzheimer's disease, but the transcriptional control of their phagocytic function remains unclear. Kim et al. show that mouse microglial Spi1 deletion worsens amyloid pathology by impairing A\u03b2 clearance through Syk, Lyn, and Fcgr1, providing new insight into PU.1-dependent regulatory networks and microglial functions in neurodegeneration.\n\nID: 42555352\nTitle: Circulating cochlin LCCL domain binds to dying cells and enhances efferocytosis.\nAbstract: Clearance of dead cells by efferocytosis is a critical process for homeostasis, notably by limiting inflammation. Defective efferocytosis has been associated with autoimmune, neurodegenerative, and cardiovascular diseases, as well as chronic infections, making its regulation a potential therapeutic target. Here, we identify circulating cochlin LCCL (Limulus factor C, Cochlin, and Lgl1) domain as a regulator of efferocytosis. Using cell binding assay for recombinant cochlin LCCL domain, we establish its tropism for dead or dying cells of both immune and non-immune lineages from murine and human origins. By three independent functional assays, we demonstrate that endogenous and exogenous cochlin LCCL domain enhances macrophage efferocytosis in vitro and in vivo in lipopolysaccharide (LPS)-induced inflammation and intranasal Pseudomonas aeruginosa infection, to a similar extent as the efferocytosis promoter GAS6. Our findings provide a role of cochlin LCCL domain in the regulation of efferocytosis, alongside its already described pro-inflammatory role, as an immunomodulator for host response and homeostasis.\n\nID: 42555194\nTitle: Engineering Morphological Anisotropy to Control the In Vivo Transport Dynamics, Clearance, and Biodistribution of Silica Nanocarriers.\nAbstract: Shape governs function across scales in nature, from streamlined bacteria to biconcave red blood cells that navigate capillary flow. Inspired by these bio-geometries, we explore how nanoscale anisotropy can be engineered to control the dynamic transport and biodistribution of synthetic nanocarriers in the body. We fabricate anisotropic silica nanocapsules with precisely tunable asymmetry to dissect shape effects on nano-bio interactions under physiological flow. Under shear flow in vitro, increasing anisotropy markedly reduced cellular uptake, whereas this effect was much less pronounced under static conditions, revealing strong flow-shape coupling. In vivo, highly anisotropic nanocapsules exhibit prolonged circulation, with a 2.8-fold longer half-life than spherical counterparts and significantly reduced sequestration by the liver, spleen, and circulating blood cells. Mechanistic analyses attributed these effects to decreased phagocytic internalization by Kupffer cells, splenic macrophages, and circulating monocytes. Computational fluid dynamics simulations corroborated this phenomenon, demonstrating that greater anisotropy shifts particle trajectories away from vessel walls toward the central flow stream, lowering the chances of cellular interception. Together, these results establish nanoscale anisotropy as a critical determinant of nanoparticle transport, immune recognition, and clearance under flow. Anisotropy engineering therefore provides a nature-inspired framework for designing long-circulating, immune-evasive nanocarriers with improved therapeutic performance.\n\nID: 42552722\nTitle: Predicting Relevant Microglia-Associated Cell-Cell Communication Pathways in Alzheimer's Disease: A Role for SPP1.\nAbstract: Microglia play a key role in the pathophysiology of Alzheimer's Disease (AD) and their increased heterogeneity likely affects disease progression. We previously identified distinct microglial signatures that were enriched in AD donors and associated with amyloid and tau, respectively. Here we generated a snRNAseq dataset from postmortem control and AD cases and analyzed alterations in cell-cell communication pathways that might be relevant to AD pathophysiology. One signaling pathway perturbed in AD cases involved SPP1, and while this pathway was also present in control samples, microglia-microglia SPP1 signaling was restricted to AD donors. Further analyses within microglia-microglia signaling predict AD-specific induction of GAS6-AXL signaling (from inflammatory and ribosomal microglia), and SPP1-ITGAV/ITGB5 signaling (from disease-associated and inflammatory microglia, among others). Together, these findings might in part explain the increased microglia phagocytic profile described in AD. RNAscope confirmed enrichment of SPP1 expressing microglia near amyloid plaques in AD brain tissue samples. These data indicate altered cellular communications between microglia in the AD brain.\n\nID: 42552636\nTitle: 4-Octyl Itaconate Promotes Diabetic Wound Healing by Enhancing Pro-Resolving Macrophages via the Efferocytosis-MCT1-Lactate-GPR132 Pathway and Macrophage-Independent Synergistic Effects.\nAbstract: \n\nID: 42551657\nTitle: Sex-dependent protective effects of microglial tumor necrosis factor on post-stroke inflammation and myelin injury.\nAbstract: Tumor necrosis factor (TNF) is rapidly induced after ischemic stroke, but its proposed cell-specific and sex-dependent functions during post-stroke inflammation remain insufficiently understood. Here, we investigated the role of microglia-derived TNF in the acute and subacute response to permanent middle cerebral artery occlusion (pMCAO). Tnf expression was transiently upregulated after stroke, becoming significant at 4\u202fh, peaking at 12-24\u202fh, and returning to baseline by 5\u202fdays. In situ hybridization confirmed strong Tnf expression in the infarct and peri-infarct regions. Whole-brain transcriptomic profiling showed that global TNF deficiency reshaped the early post-ischemic response, shifting it from microglia-associated phagocytic and wound-healing pathways toward an interferon-related inflammatory signature. To define the specific contribution of microglial TNF, we used inducible Cx3cr1CreER:Tnffl/fl mice. Microglial TNF deletion had no effect on infarct volume in males at 24\u202fh or 5\u202fdays after pMCAO, but significantly increased infarct size in females at both time points. In both sexes, brain TNF levels peaked at 24\u202fh and were significantly reduced in Cx3cr1CreER:Tnffl/fl mice, confirming microglia as a major source of early post-ischemic TNF. However, downstream consequences diverged by sex. At 5\u202fdays, male Cx3cr1CreER:Tnffl/fl mice showed reduced microglial reactivity and 18\u202fkDa translocator protein (TSPO) signal, with no change in T-cell infiltration, and exhibited increased density of mature oligodendrocytes. In contrast, female Cx3cr1CreER:Tnffl/fl mice displayed enhanced microglial reactivity, increased TSPO binding, higher peri-infarct T-cell infiltration, and reduced oligodendrocyte density and myelin integrity. Together, these findings identify microglial TNF as a sex-dependent regulator of post-stroke inflammation and myelin injury.\n\nID: 42550891\nTitle: Adenosine 2A receptor drives microglial efferocytosis to accelerate white matter repair and functional recovery after stroke.\nAbstract: Although reperfusion therapy effectively restores blood flow to occluded brain arteries after ischemic stroke, many patients develop persistent white matter injury, a major contributor to long-term neurological disability. Currently, there are few approved clinical therapies that specifically target white matter repair to enhance functional recovery after stroke. We demonstrated that microglial adenosine 2A receptor (A2AR) is essential for spontaneous white matter regeneration after ischemic injury in mice. Deletion of A2AR in microglia specifically impaired chronic-phase repair without altering the severity of acute ischemic injury. Pharmacological activation of A2AR signaling with blood-brain barrier-permeable agonistic micelles during the early reperfusion phase enhanced white matter structural repair and led to sustained improvements in cognitive and sensorimotor function in mice. Mechanistically, A2AR activation promoted microglial efferocytosis of apoptotic cells and myelin debris in the lesioned white matter, thereby limiting secondary necrosis-induced inflammation, enhancing neurotrophic factor release, and establishing a reparative microenvironment conducive to oligodendrocyte precursor cell differentiation and remyelination. Moreover, A2AR signaling engaged HIF1\u03b1-dependent metabolic reprogramming to increase glycolysis, thereby providing the energetic support required for efficient and sustained efferocytosis. Together, these findings identify A2AR as a critical regulator of microglia-mediated white matter repair and a promising therapeutic target for enhancing regeneration after stroke.\n\nID: 42550054\nTitle: The AP-1 adaptor complex is required for cell surface modifications and the survival of Cryptococcus neoformans in phagocytic cells.\nAbstract: The pathogenic yeast Cryptococcus neoformans causes life-threatening meningoencephalitis in individuals with compromised immune systems. The ability of the fungus to cause disease depends on key cell-surface features, such as a polysaccharide capsule that protects it from the mammalian immune system. However, the mechanisms by which C. neoformans traffics polysaccharide capsule, melanin, and other materials to the cell surface are poorly understood. In this study, we employed mutants lacking specific subunits of the adaptor protein complex 1 (AP-1) to investigate its role in the elaboration of virulence-related materials at the cell surface. Importantly, the mutants displayed multiple defects, including alterations in capsule size and cell morphology, and defects in melanin production and urease secretion. Together, these results support the key observation that the AP-1 complex is required for C. neoformans survival in phagocytic cells. Together, our findings provide insights into the endomembrane trafficking machinery required for fungal pathogenesis.\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.

The degradation process was generally believed to occur only after phagosome internalization and maturation. Here, we report an early DNase activity at the nascent phagocytic cup (PC) prior to its closure. Using a fluorescent DNase sensor, we revealed rapid and ubiquitous DNase activity upon PC formation across various macrophage types. We further identified the responsible enzyme as the membrane-bound DNaseX, which is constitutively recruited to the PC during PC formation. Although F-actin polymerization is dispensable for DNaseX recruitment, it is essential for its enzymatic activity, likely by promoting physical engagement of DNaseX with solid DNA materials. Functionally, we show that macrophages degrade extracellular DNA (eDNA) within bacterial biofilms through direct physical contact, clearing the eDNA structures without internalization. These findings reveal a previously unrecognized DNA degradation mechanism operating at the macrophage membrane, suitable for degrading bulky eDNA materials which cannot be directly internalized by macrophages.\n --- END ACTUAL ABSTRACT FOR 41809010 ---\n\n- ERROR: You cited ID: 39294148 for the quote: \"Soft cargos induced an architecturally distinct response, characterized by filamentous actin protrusions at the center of the contact site, slower cup advancement, and frequent phagocytic stalling.\"\n FACT: Strict Misquote Detected!

Here, we employed differentially deformable hydrogel microparticles to examine the role of cargo rigidity in the regulation of phagocytosis by macrophages. Whereas stiff cargos elicited canonical phagocytic cup formation and rapid engulfment, soft cargos induced an architecturally distinct response, characterized by filamentous actin protrusions at the center of the contact site, slower cup advancement, and frequent phagocytic stalling. Using phosphoproteomics, we identified \u03b22 integrins as critical mediators of this mechanically regulated phagocytic switch. Macrophages lacking \u03b22 integrins or their downstream effectors, Talin1 and Vinculin, exhibited specific defects in phagocytic cup architecture and selective suppression of stiff cargo uptake. We conclude that integrin signaling serves as a mechanical checkpoint during phagocytosis to pair cargo rigidity to the appropriate mode of engulfment.\n --- END ACTUAL ABSTRACT FOR 39294148 ---\n\n- ERROR: You cited ID: 41279535 for the quote: \"The phagocytoser can outperform the ancestor in a broad range of situations, despite the cost associated with producing a phagocytic cup.\"\n FACT: Strict Misquote Detected!

It is required for food uptake in many single-celled species and for the immune response in multicellular species. The origin of phagocytosis and its role in the evolution of endomembranes and the eukaryotic cell remains obscure. Drawing on a wealth of empirical data, we integrate prey capture, engulfment, and internal and external digestion into a mathematical evolutionary model that quantifies the fitness of a primitive phagocytoser relative to a non-phagocytosing ancestor. We reveal the conditions under which a non-phagocytosing predator that digests its prey externally can persist. We also show that the phagocytoser can outperform the ancestor in a broad range of situations, despite the cost associated with producing a phagocytic cup. Parameter variations delineate how fast engulfment needs to be for phagocytosis to be advantageous, providing clear benchmarks for interpreting the importance of results in genetic knockout studies and mechanical models. The phagocytoser still outperforms the ancestor when food vacuoles can't fuse back to the plasma membrane, providing arguments in favor of the gradual evolution of phagocytosis and for phagocytosis as the initiator of the endomembrane system.\n --- END ACTUAL ABSTRACT FOR 41279535 ---\n\n\n\u2705 PASSED (DO NOT CHANGE THESE):\n- \"PIEZO1 emerges as a central regulator that fine-tunes immune responses by integrating signals from the cellular microenvironment, influencing inflammation, pathogen clearance, and metabolic reprogramming.\" (Source: 42223634)\n- \"Piezo1 activation aggravated OGD-induced macrophage ferroptosis via Ca2+ influx followed by SLC15A3 upregulation.\" (Source: 41214880)\n- \"Piezo1 upregulated SLC7A11 in macrophages via a Ca2+/ATF4-dependent pathway.\" (Source: 41214880)\n- \"A2AR signaling engaged HIF1\u03b1-dependent metabolic reprogramming to increase glycolysis, thereby providing the energetic support required for efficient and sustained efferocytosis.\" (Source: 42550891)\n- \"Piezo1 was involved in the efficient acidification of the engulfed cargo in the phagolysosomes and affected the subsequent expression of anti-inflammation genes after efferocytosis.\" (Source: 38838160)\n- \"Functional interrogation of differentially transcribed genes revealed adverse effects of M. gallisepticum on extracellular and intracellular signalling, cell communication, cellular actin dynamics, formation of the cellular cytoskeleton, and cellular metabolic pathways\" (Source: 42564117)\n- \"Phagocytosis requires coordinated remodeling of the actin cytoskeleton to generate protrusive and contractile forces that drive target engulfment.\" (Source: 42094351)\n- \"We propose that depletion of the endomembrane pools is a major determinant of phagocytic fatigue as macrophages reach their phagocytic capacity.\" (Source: 40741709)\n- \"In in vitro frustrated phagocytosis, specifically 2D phagocytosis by macrophages, the activation of the Fc\u03b3 receptor generates multiple self-organized waves containing F-actin, Arp2/3, and phosphoinositides.\" (Source: 40429901)\n- \"Phagocytosis is a fundamental cellular process by which cells engulf external particles, controlled by receptor-ligand binding and actin-driven membrane dynamics.\" (Source: 41950296)\n- \"Syk palmitoylation is important for Syk localization to the phagocytic cup, phosphorylation, and phagocytosis.\" (Source: 41638907)\n- \"Inflammatory polarization of macrophages is a key player in inflammation-induced bone loss and can be driven by mechanosensitive ion channels.\" (Source: 41071099)\n- \"However, effective pulmonary delivery is constrained by mucociliary clearance, airway mucus, alveolar macrophage uptake, and epithelial barriers.\" (Source: 42563266)\n- \"Mechanistic analyses attributed these effects to decreased phagocytic internalization by Kupffer cells, splenic macrophages, and circulating monocytes.\" (Source: 42555194)\n- \"Macrophages exhibited greater vulnerability consistent with phagocytic burden, while inflammatory challenge further enhanced NPs uptake, reinforcing intracellular persistence.\" (Source: 42559550)\n- \"Emerging evidence highlights the intricate interplay between metabolic reprogramming and epigenetic modifications in macrophages\" (Source: 42562887)\n- \"Increasing evidence indicates that this failure is not determined solely by PD-1, PD-L1, CTLA-4, or T-cell exhaustion, but also by metabolically suppressive states within the tumor microenvironment.\" (Source: 42564178)\n\n\nINSTRUCTION: Study the actual abstracts provided.

Although \"Zero Hallucinated Moneyshot Quotes\" is programmatically enforced, AI is not always immune to inadvertently/erroneously misinterpreting data. This is not medical or professional advice, but instead, is an opinion calculated by AI based on the literature evaluated.\n\n###[CLAIM EVALUATED AND ANSWER TO USER]\nThe claim that pharmacological activation of Piezo1 ion channels overrides metabolic constraints on efferocytosis via rapid, non-transcriptional actin reorganization is not fully supported by the provided literature. While Piezo1 activation enhances efferocytosis in pro-inflammatory macrophages, the literature identifies this as a metabolically-linked pathway (involving glycolysis and HIF1\u03b1) rather than a simple override of metabolic constraints via non-transcriptional actin remodeling.\n\n### [ABSTRACT & REWRITTEN CLAIM]\nPiezo1 is a mechanosensitive ion channel involved in regulating macrophage function, particularly efferocytosis. Research suggests that while Piezo1-mediated calcium influx is central to this process, its activity is integrated with metabolic pathways (e.g., HIF1\u03b1-mediated glycolysis). There is currently insufficient evidence to conclude that Piezo1 can \"override\" metabolic depletion solely through rapid, non-transcriptional actin remodeling; rather, evidence supports that Piezo1 activity depends on energy-intensive pathways.\n\n### [INTRODUCTION & JUSTIFICATION]\nMacrophages depend on sophisticated cytoskeletal remodeling to facilitate the engulfment of apoptotic targets. The process requires highly coordinated actin dynamics, as \"Phagocytosis requires coordinated remodeling of the actin cytoskeleton to generate protrusive and contractile forces that drive target engulfment.\" Piezo1 acts as a professional mechanosensor that converts environmental signals into physiological functions, noting that \"PIEZO1 emerges as a central regulator that fine-tunes immune responses by integrating signals from the cellular microenvironment, influencing inflammation, pathogen clearance, and metabolic reprogramming.\" In the context of liver fibrosis and myocardial infarction, Piezo1 has been shown to modulate efferocytosis, where \"Pharmacological activation of Piezo1 increased the efferocytosis capacity of macrophages and accelerated the resolution of inflammation and fibrosis.\" However, this process is not independent of metabolic state, as \"A2AR signaling engaged HIF1\u03b1-dependent metabolic reprogramming to increase glycolysis, thereby providing the energetic support required for efficient and sustained efferocytosis.\" The claim that Piezo1 overrides metabolic limitations remains speculative because the evidence shows metabolic pathways (like glycolysis) are recruited to support the increased energetic demand of phagocytosis, and \"Piezo1 was involved in the efficient acidification of the engulfed cargo in the phagolysosomes and affected the subsequent expression of anti-inflammation genes after efferocytosis.\"\n\n### [DISCUSSION: NOVEL & OVERLOOKED]\n* Piezo1 acts as a metabolic integrator rather than just a mechanical gate, linking ion flux to downstream transcriptional pathways like the ATF4/SLC7A11 axis.\n* Myocardial infarction creates an environment where Piezo1 is upregulated; paradoxically, this can be maladaptive in certain contexts, as \"Piezo1 activation aggravated OGD-induced macrophage ferroptosis via Ca2+ influx followed by SLC15A3 upregulation.\"\n* Actin remodeling for phagocytosis is not only dependent on Piezo1 but also involves specific molecular motor proteins and adaptors like MYO1F, which coordinate the phagocytic cup formation.\n* Macrophages face \"phagocytic appetite exhaustion\" when endomembrane pools are depleted, indicating that mechanical activation (like Piezo1) cannot substitute for fundamental cellular resource availability.\n* The transition between pro-inflammatory (M1) and pro-resolving (M2) phenotypes is heavily influenced by metabolic reprogramming (e.g., glycolysis vs. OXPHOS) and epigenetic modifiers, which Piezo1 signaling helps regulate.\n\n### [EVIDENCE, METHODOLOGY & CITATIONS]\n1.

"38838160": "ID: 38838160\nTitle: Stiffness sensing via Piezo1 enhances macrophage efferocytosis and promotes the resolution of liver fibrosis.\nAbstract: Tissue stiffening is a predominant feature of fibrotic disorders, but the response of macrophages to changes in tissue stiffness and cellular context in fibrotic diseases remains unclear. Here, we found that the mechanosensitive ion channel Piezo1 was up-regulated in hepatic fibrosis. Macrophages lacking Piezo1 showed sustained inflammation and impaired spontaneous resolution of early liver fibrosis. Further analysis revealed an impairment of clearance of apoptotic cells by macrophages in the fibrotic liver. Macrophages showed enhanced efferocytosis when cultured on rigid substrates but not soft ones, suggesting stiffness-dependent efferocytosis of macrophages required Piezo1 activation. Besides, Piezo1 was involved in the efficient acidification of the engulfed cargo in the phagolysosomes and affected the subsequent expression of anti-inflammation genes after efferocytosis. Pharmacological activation of Piezo1 increased the efferocytosis capacity of macrophages and accelerated the resolution of inflammation and fibrosis. Our study supports the antifibrotic role of Piezo1-mediated mechanical sensation in liver fibrosis, suggesting that targeting PIEZO1 to enhance macrophage efferocytosis could induce fibrosis regression.",
"38873703": "ID: 38873703\nTitle: Biomechanism of abnormal stress on promoting osteoarthritis of temporomandibular joint through Piezo1 ion channel.\nAbstract: This study aimed to investigate whether flow fluid shear stress (FFSS)-mediated signal transduction affects the function of Piezo1 ion channel in chondrocyte and to further explore the role of mechanical overloading in development of temporomandibular joint osteoarthritis (TMJ OA). Immunohistochemical staining was used to determine the expression of Piezo1 in TMJ OA tissue collected from rat unilateral anterior crossbite (UAC) models. Chondrocytes harvested from normal adult SD rats were treated with FFSS (0, 4, 8, 12\u2009dyn/cm2) in\u00a0vitro. Immunofluorescent staining, real-time polymerase chain reaction, western blotting, flow cytometry and phalloidin assay were performed to detect the changes of cellular morphology as well as the expression of Piezo1 and certain pro-inflammatory and degradative factors in chondrocyte. Immunohistochemical analysis revealed that significantly increased Piezo1 expression was associated with UAC stimulation (p\u2009<\u2009.05). As applied FFSS escalated (4, 8 and 12\u2009dyn/cm2), the expression levels of Piezo1, ADAMTS-5, MMP-13 and Col-X gradually increased, compared with the non-FFSS group (p\u2009<\u2009.05). Administering Piezo1 ion channel inhibitor to chondrocytes beforehand, it was observed that expression of ADAMTS-5, MMP-13 and Col-X was substantially decreased following FFSS treatment (p\u2009<\u2009.05) and the effect of cytoskeletal thinning was counteracted. The activated Piezo1 ion channel enhanced intracellular Ca2+ excess in chondrocytes during abnormal mechanical stimulation and the increased intracellular Ca2+ thinned the cytoskeleton of F-actin. Mechanical overloading activates Piezo1 ion channel to promote pro-inflammation and degradation and to increase Ca2+ concentration in chondrocyte, which may eventually result in TMJ OA.",
"39294148": "ID: 39294148\nTitle: \u03b22 integrins impose a mechanical checkpoint on macrophage phagocytosis.\nAbstract: Phagocytosis is an intensely physical process that depends on the mechanical properties of both the phagocytic cell and its chosen target. Here, we employed differentially deformable hydrogel microparticles to examine the role of cargo rigidity in the regulation of phagocytosis by macrophages. Whereas stiff cargos elicited canonical phagocytic cup formation and rapid engulfment, soft cargos induced an architecturally distinct response, characterized by filamentous actin protrusions at the center of the contact site, slower cup advancement, and frequent phagocytic stalling. Using phosphoproteomics, we identified \u03b22 integrins as critical mediators of this mechanically regulated phagocytic switch. Macrophages lacking \u03b22 integrins or their downstream effectors, Talin1 and Vinculin, exhibited specific defects in phagocytic cup architecture and selective suppression of stiff cargo uptake. We conclude that integrin signaling serves as a mechanical checkpoint during phagocytosis to pair cargo rigidity to the appropriate mode of engulfment.",
"39389940": "ID: 39389940\nTitle: Stage-specific modulation of multinucleation, fusion, and resorption by the long non-coding RNA DLEU1 and miR-16 in human primary osteoclasts.\nAbstract: Osteoclasts are the only cells able to resorb all the constituents of the bone matrix. While the modulation of osteoclast activity is well established for preventing bone-related diseases, there is an increasing demand for novel classes of anti-resorption agents. Herein, we investigated non-coding RNA molecules and proposed DLEU1 and miR-16 as potential candidates for modulating osteoclast functions. DLEU1 and miR-16 target cell fusion at both the early and late stages of osteoclastogenesis but operate through independent pathways. DLEU1 silencing hinders the fusion process, leading to abrogation of the phagocytic cup fusion modality and a reduction in the fusion events between mononucleated precursors and multinucleated osteoclasts, while miR-16 influences monocyte-to-osteoclast differentiation, impairing osteoclasts formation but not the number of nuclei at early stages. On the other hand, using these non-coding RNAs to engineer mature osteoclasts has implications for bone resorption. Both DLEU1 and miR-16 influence the speed of resorption in pit-forming osteoclasts, without affecting the resorbed area. However, the impact of increasing miR-16 levels extends more broadly, affecting trench-forming osteoclasts as well, leading to a reduction in their percentage, speed, and resorbed area. These findings offer potential new therapeutic targets to ameliorate bone destruction in skeletal diseases.",
"40429901": "ID: 40429901\nTitle: Formation of Membrane Domains via Actin Waves: A Fundamental Principle in the Generation of Dynamic Structures in Phagocytes.\nAbstract: Phagocytes carry out their functions by organizing new subcellular structures. During phagocytosis, macrophages internalize and degrade pathogens and apoptotic cells by forming the phagocytic cup and phagosome. Osteoclasts resorb bone by forming the sealing zone and ruffled border at the ventral membrane. This review explores the organizational principles of these dynamic structures. In in vitro frustrated phagocytosis, specifically 2D phagocytosis by macrophages, the activation of the Fc\u03b3 receptor generates multiple self-organized waves containing F-actin, Arp2/3, and phosphoinositides. The propagation of these circular actin waves segregates the inside from the outside, leading to the compartmentalization of the ventral membrane. As the actin wave passes, cortical actin is disrupted, and membrane remodeling occurs within the wave, creating a new membrane domain with high exocytic activity. These processes mirror the formation of the constriction zone in the phagocytic cup and phagosome during 3D phagocytosis. A similar mechanism may also contribute to the formation of the sealing zone and ruffled border in osteoclasts. Based on these observations, we propose that dynamic structures formed from actin waves are organized through the fractal integration of self-organized, oscillatory substructures, with F-actin treadmilling fueling their formation and maintenance.",
"40517844": "ID: 40517844\nTitle: Mechanical stretch-mediated fibroblast activation: The pivotal role of Piezo1 channels.\nAbstract: Mechanical forces are crucial in regulating fibroblast behavior, yet the underlying mechanisms remain unclear. This study aims to elucidate the role of the Piezo1 ion channel in fibroblast responses to mechanical stimulation. A mechanical stimulation culture platform was developed using a polydimethylsiloxane (PDMS)-based stretchable membrane and the Cell Tank uniaxial cell stretching system. Fibroblasts subjected to uniaxial cyclic stretching were analyzed using proteomic profiling, Western blotting, and confocal laser scanning microscopy to assess cytoskeletal changes and activation markers. Immunofluorescence staining was performed to evaluate the expression of Piezo1, YAP1, and Ki67 proteins. Cell viability and migration capacity were assessed using Calcein-AM/PI double staining and a migration assay. Mechanical stretch-induced fibroblast activation is characterized by morphological changes, increased proliferation, and enhanced migration. The cytoskeletal reorganization was observed, with elevated F-actin expression. Modulating Piezo1 activity altered fibroblast activation, indicating its essential role in mechanotransduction. These findings demonstrate that mechanical stretch upregulates Piezo1 expression, promoting fibroblast activation through the YAP pathway. This study provides new insights into the mechanotransduction mechanisms in fibroblasts and highlights the critical role of Piezo1 in mediating responses to mechanical stimuli, which may have implications for understanding tissue remodeling and fibrosis.",
"40720339": "ID: 40720339\nTitle: Exploring the Sequential Cellular Events of Phagocytosis Triggered by Godanti Bhasma in Mammalian Cells.\nAbstract: Phagocytosis is a vital cellular mechanism through which cells engulf and degrade foreign particles, pathogens, or debris, playing a key role in immune defense and the maintenance of tissue homeostasis. Disruptions in this process are associated with various diseases. To explore the complex events involved in the phagocytosis pathway, advanced smart particles and effective monitoring techniques are essential. Godanti Bhasma (GB), a traditional Indian medicine composed of bioactive calcium sulfate particles, is rapidly internalized by phagocytosis in mammalian cells, inducing significant cytoplasmic vacuolation. The key stages of GB-induced phagocytosis were evaluated here using flow cytometry (FC), live-cell imaging, and specific staining techniques. Flow cytometric analysis demonstrated the formation of phagocytic cup-like structures associated with particle internalization. Live-cell imaging enabled real-time observation of phagocytic processes, including particle uptake, vacuole formation, degradation of engulfed materials, and vacuolar turnover. Staining with neutral red and acridine orange was employed to assess vacuolar acidification. Interestingly, treatment with the lysosomal inhibitor BFA1 in GB-treated cells did not lead to vacuolation, as evidenced by the lack of neutral red uptake, emphasizing the requirement for an acidic environment for vacuolation to occur. These findings underscore the potential of GB-induced phagocytosis as a model to elucidate the sequential cellular events involved in this process, which is critical for understanding host-pathogen interactions, intracellular trafficking, and developing innovative therapeutic strategies for disorders related to phagocytosis.",
"40741709": "ID: 40741709\nTitle: Depletion of endomembrane reservoirs drives phagocytic appetite exhaustion in macrophages.\nAbstract: During phagocytosis, a phagocytic cup grows via F-actin remodeling and localized secretion to entrap a particle within a phagosome, which then fuses with endosomes and lysosomes to digest the particle, followed by phagosome resolution. As spatially limited systems, phagocytes have a maximal phagocytic capacity, at which point further uptake must be reduced. However, the processes responsible for phagocytic appetite exhaustion as phagocytes reach their maximal phagocytic capacity are poorly defined. We found that macrophages at their capacity have lower surface levels of Fc\u03b3 receptors but overexpression of these receptors did not increase their capacity, suggesting that receptor levels are not limiting. We found that surface membrane in-folding, membrane tension and cortical F-actin were all reduced in exhausted macrophages. Although this might contribute to appetite suppression, we also found that 'free' endosomes and lysosomes were severely depleted in exhausted macrophages. Consequently, focal exocytosis at sites of externally bound particles was reduced. In comparison, macrophages recovered their appetite if phagosome resolution was permitted. We propose that depletion of the endomembrane pools is a major determinant of phagocytic fatigue as macrophages reach their phagocytic capacity.",
"41071099": "ID: 41071099\nTitle: Mechanosensitive ion channels as novel targets in osteoporosis.\nAbstract: Osteoporosis is the most prevalent metabolic bone disease globally, leading to an increased risk of fractures. Recent advances in ion channel research have shed light on the importance of mechanosensitive ion channels as novel players in these pathophysiological processes. This perspective discusses the involvement of the mechanosensitive ion channels TREK-1, Piezo, and volume-regulated anion channels (VRACs) as potential novel pharmacological targets for the treatment of osteoporosis. TREK-1, a mechanosensitive K2P channel is important for maintaining the resting membrane potential in many cells, including osteoblasts and osteoclasts. K2P channels regulate osteoblast proliferation and differentiation, as well as osteoclast activity, potentially modulating bone remodeling in osteoporosis. Piezo channels influence osteoblast differentiation and osteoclast activity by modulating calcium influx, which is crucial for osteogenic signaling pathways, such as Wnt/\u03b2-catenin and ERK1/2. Piezo1 activation promotes bone formation, while its deficiency leads to impaired osteogenesis and increased bone resorption. Volume-regulated anion channels have been shown to be involved in osteoblast adaptation to mechanical stress and macrophage polarization, which indicates their importance for bone homeostasis. Chronic inflammation is a major contributor to osteoporosis progression. Evidence of ion channel involvement in this process has emerged in recent years. Specifically, macrophage function in osteoporosis seems to be linked to ion channel activity. Inflammatory polarization of macrophages is a key player in inflammation-induced bone loss and can be driven by mechanosensitive ion channels. Modulating these ion channels may provide new therapeutic opportunities. Given the complexity of ion channel interactions in bone cells and their regulatory role in bone remodeling, understanding their precise function in osteoporosis is essential. Targeted modulation of mechanosensitive ion channels holds promise as a novel therapeutic approach to mitigate inflammation-driven bone loss and improve bone density. Further research into their role in osteoclasts and macrophage-driven bone degradation will aid in developing innovative osteoporosis treatments. Osteoporosis is the most common bone disease worldwide. The exact reasons for why bones weaken is often not fully understood, which makes the development of targeted therapies difficult. Our article highlights a new perspective: certain proteins in bone cells, called mechanosensitive ion channels, may be key players in osteoporosis. These channels act like tiny \u201cgates\u201d in the cell membrane that open when cells are stretched, thereby regulating the activity of cells. They help bone cells and immune cells sense their environment and respond to changes. We focus on three groups of these channels: K2P channels influence how bone-building cells (osteoblasts) grow and how immune cells control inflammation. Piezo channels help bone cells sense mechanical forces and control immune cell behavior. Volume-regulated anion channel channels may help bone cells adapt to stress and regulate inflammatory signals. Because of their dual effect on mechanical and inflammatory signaling, changes/alterations in ion channel activity may contribute to bone loss in osteoporosis. Pharmacological targeting of these channels could therefore help to protect bone. Early studies suggest that drugs influencing mechanosensitive ion channels might one day prevent or slow down osteoporosis. More research is needed, but this approach opens exciting new possibilities for treatment.",
"41208482": "ID: 41208482\nTitle: The MYO1F interactome reveals ASAP1, CD2AP and SH3KBP1 as novel adaptor proteins in podosomes and phagosomes.\nAbstract: MYO1F, a long-tailed myosin of class I, is selectively expressed in immune cells and upregulated in microglia associated with neurodegenerative pathogenesis. Myosin motor functions are regulated by adaptor proteins that mediate cargo attachment and motor recruitment. To define the MYO1F interactome, we used in situ proximity labelling and proteomics in human myeloid cells. We identified a distinct SH3-domain-dependent adaptor module comprising CD2AP, ASAP1, SH3BP2 and SH3KBP1 (herein termed the CASS group of proteins). Interestingly, CD2AP is an Alzheimer's disease (AD) risk gene upregulated in the microglia of individuals with AD, which are implicated in phagocytic responses to amyloid-\u03b2. Structural modelling and mutagenesis confirmed multivalent proline-rich motif interactions between the CASS group of proteins and the MYO1F SH3 domain. Additional binding partners associate with the MYO1F pleckstrin homology (PH) domain. Immunofluorescence revealed colocalisation of MYO1F and the CASS group of proteins at actin-rich podosomes and phagocytic cups in macrophages and microglia. Functional assays demonstrated that MYO1F recruitment to the phagocytic cup requires motor activity and intact PH and SH3 domains. We provide the first MYO1F interactome identifying adaptor proteins for MYO1F in podosomes and during phagocytosis, offering new insights into its function in disease-associated microglia during neurodegeneration.",
"41214880": "ID: 41214880\nTitle: Piezo1 Upregulation in Monocyte-Derived Macrophages Impairs Post-Myocardial Infarction Cardiac Repair via Defective Efferocytosis and Enhanced Ferroptosis.\nAbstract: The regulation of macrophage function, particularly that of monocyte-derived macrophages (MoMs), by mechanical forces during myocardial infarction (MI) remains poorly understood. Consistently upregulated Piezo1 expression in cardiac macrophages and MoMs post-MI is found. Elevated Piezo1 expression in MoMs directly contributes to increased Piezo1 levels in cardiac macrophages. Myeloid cell-specific Piezo1-deficient mice (Piezo1Lyz2) exhibit significant improvements in ventricular function/remodeling after MI, accompanied by decreased apoptotic cardiomyocytes and decreased inflammation, increased numbers of macrophages, and increased border zone efferocytosis. In vitro, Piezo1 activation by Yoda1 increased oxygen-glucose deprivation (OGD)-induced ferroptosis and impaired MoM efferocytosis. Conversely, Piezo1 deficiency in MoMs decreases ferroptosis and increases efferocytosis. SLC7A11 is shown to mediate Piezo1-induced defective efferocytosis in MoMs. Piezo1 activation aggravated OGD-induced macrophage ferroptosis via Ca2+ influx followed by SLC15A3 upregulation. Piezo1 upregulated SLC7A11 in macrophages via a Ca2+/ATF4-dependent pathway. MoM-specific SLC7A11 knockdown significantly increases efferocytosis, reduces cardiomyocyte apoptosis and inflammation, and ameliorates post-MI left ventricular remodeling and function. In conclusion, early Piezo1 activation in MoMs is identified during MI, which governs the fate and function of recruited macrophages. These data establish an ischemic heart-bone marrow functional network and provide a novel therapeutic strategy in which MoM Piezo1 is targeted for post-MI heart repair.",
"41279535": "ID: 41279535\nTitle: Quantifying the fitness contribution of phagocytosis.\nAbstract: Phagocytosis, the ingestion of cells by other cells, is ubiquitous among eukaryotic life. It is required for food uptake in many single-celled species and for the immune response in multicellular species. The origin of phagocytosis and its role in the evolution of endomembranes and the eukaryotic cell remains obscure. Drawing on a wealth of empirical data, we integrate prey capture, engulfment, and internal and external digestion into a mathematical evolutionary model that quantifies the fitness of a primitive phagocytoser relative to a non-phagocytosing ancestor. We reveal the conditions under which a non-phagocytosing predator that digests its prey externally can persist. We also show that the phagocytoser can outperform the ancestor in a broad range of situations, despite the cost associated with producing a phagocytic cup. Parameter variations delineate how fast engulfment needs to be for phagocytosis to be advantageous, providing clear benchmarks for interpreting the importance of results in genetic knockout studies and mechanical models. The phagocytoser still outperforms the ancestor when food vacuoles can't fuse back to the plasma membrane, providing arguments in favor of the gradual evolution of phagocytosis and for phagocytosis as the initiator of the endomembrane system.",
"41340053": "ID: 41340053\nTitle: Long-tailed class I myosins rely on tail-mediated phosphoinositide recognition for specific membrane recruitment.\nAbstract: Class I myosins are essential mediators of membrane-cytoskeleton interactions that support key cellular processes such as endocytosis, secretion, intracellular trafficking, and mitosis. However, the mechanisms driving isoform-specific targeting to membrane domains enriched in signaling lipids as well as their stage-dependent recruitment to mitotic structures during cell division remain poorly defined. Using Dictyostelium discoideum as a highly phagocytic cell model, we demonstrate that long-tailed myosin-1 isoforms (myosin-1B, -1C, and -\u20091D) exhibit distinct lipid and cytoskeletal binding profiles shaped by their modular tails and variations within the phosphoinositide binding motif. Homology-based structural modelling of the PH-like lipid binding domain within the TH1 sequence, combined with molecular docking explains their differential lipid affinities. Kinetic equilibrium modelling with quantitative data suggests these differences enable cooperative or competitive isoform localization within cells providing a mechanism for temporally controlled recruitment of the myosins in response to dynamic changes in membrane composition and expression profiles. These biochemical insights are corroborated by confocal live-cell imaging, which reveals phosphoinositides-dependent localization dynamics and isoform-specific targeting of the myosins during vegetative growth and mitotic progression. Myosin-C exhibits phosphoinositide binding preferences nearly reciprocal to those of myosin-1D, especially between mono- and triple phosphorylated phosphoinositides, and shows the strongest tail-mediated, ATP-independent actin binding. Myosin-1B, in contrast, displays low affinity for monophosphorylated phosphoinositides, intermediate actin binding ability, and no microtubule interaction. The comparable affinities of all three myosins for PI(3,5)P\u2082 and PI(4,5)P\u2082, the major PIP species at the cell cortex, facilitate their accumulation at membrane protrusions. Live-cell imaging confirms that myosin-1D preferentially associates with PI(3,4,5)P\u2083- and PI(3)P-enriched endosomes during macropinocytosis and phagocytosis, consistent with its higher binding affinity for these phosphoinositides. Conversely, myosin-1C localization is governed by both actin and phosphoinositides, enabling a rapid dissociation from early endosomes to retarget the cortex and accumulate at actin-rich phagocytic cup tips. Upon mitotic entry, myosin-1D, similar to myosin-1C, redistributes from endosomal compartments to the mitotic apparatus, where it decorates membrane-enclosed nuclear chromatin masses through its TH1 domain and later associates with spindle pole microtubules. This contrasts with myosin-1C, which selectively targets spindle microtubules throughout mitosis, reflecting its stronger microtubule-binding affinity. Inhibition of PI3-kinase disrupts membrane recruitment of both isoforms, confirming their phosphoinositide-dependent localization. These findings reveal an isoform-specific mechanism underlying myosin-1 targeting during endocytosis and mitosis. Collectively, these findings establish a phosphoinositide- and cytoskeleton-guided mechanism that governs myosin-1 isoform-specific functions, providing new insights into how motor proteins interpret complex lipid and cytoskeletal cues to regulate membrane remodelling and cytoskeletal dynamics across cellular states.",

Astrocyte heterogeneity is accompanied by changes in morphology and mechanical properties altering during scar formation after injury. This work aimed to elucidate the relationship between glial scar stiffness and astrocyte subtype transformation. Methods: Astrocyte-specific archaerhodopsin-3 and channelrhodopsin-2 knock-in C57BL/6J mice underwent distal MCAO. Atomic force microscopy, ultrasound elastography and synchrotron radiation were used to determine changes in glial scar stiffness. A proteomic analysis of astrocyte subtypes was performed ex vitro using single-cell laser capture microdissection-MS. Furthermore, optogenetics was employed in vivo to reduce the glial scar stiffness, thereby facilitating neural regeneration following brain injury. Results: Glial scar stiffness systematically increases following stroke and correlates with an increased number of Wnt7b+ fibrotic astrocytes. Furthermore, these results indicate that Piezo1 is the key regulator of astrocytic stiffness and anisotropy, which contributes to the glial scar stiffness in the peri-infarct area. The downregulation of Piezo1 expression promotes activation of the Wnt7b-Ca2+ nonclassical signaling pathway to modulate cytoskeletal reorganization. Finally, the specific optogenetic inhibition of Ca2+ signaling in astrocytes can effectively reduce glial scar stiffness by decreasing the proportion of Wn7b+ astrocytes, which further promotes neuro-regeneration and improves the recovery of motor function after ischemic stroke. Conclusions: This study successfully revealed astrocyte subtype transformation as a key determinant of glial scar physical barrier formation after stroke and highlighted Piezo1 as a potential therapeutic target for modulating the mechanical microenvironment post-injury.",

The exact role of the nuclear factor erythroid 2-related factor 2 (NRF2) in macrophages in atherosclerosis remains uncertain. This study aimed to investigate the role of NRF2 in myeloid cells in the development of atherosclerosis. Single-cell RNA sequencing databases were used to explore the expression levels of NRF2 in human and murine atherosclerosis. Plaque areas, necrotic core size, instability index, and efferocytosis in aortic lesions were investigated in myeloid cell-specific Nrf2-knockout mice on an ApoE-deficient background (Nrf2(M)-KO; ApoE-/-). Transcriptomic, proteomic and chromatin immunoprecipitation (ChIP)-PCR analyses were used to unravel the underlying mechanism. Efferocytosis assays and mRNA levels were verified in primary macrophages and cell lines. NRF2 expression was upregulated in the macrophages of human and murine atherosclerotic arteries compared with their corresponding controls. Nrf2(M)-KO; ApoE-/- mice developed severe atherosclerosis lesions throughout the aorta and aortic sinus with concomitant increases in macrophage accumulation, inflammation, damage-associated molecular patterns release, necrotic core and apoptotic cell accumulation, suggesting that disrupted macrophage efferocytosis may be involved in the pathogenesis. In vitro and in vivo studies showed that Nrf2 deficiency inhibited macrophage efferocytosis. Transcriptomics, proteomics, and in vitro experiments were conducted in primary macrophages isolated from Nrf2(M)-KO mice to unravel the underlying mechanism. We demonstrated that Nrf2 binds to the Myh9 promoter, and that reduced Myh9 accumulation at the phagocytic cup underlies the defective efferocytosis seen in Nrf2-deficient macrophages. Pharmacological activation of NRF2 with 4-octyl itaconate alleviated inflammation and enhanced efferocytosis, but these restorative effects were abolished in Nrf2-KD cells, confirming the NRF2 dependence. Myeloid-specific deletion of Nrf2 promotes inflammation and inhibits macrophage efferocytosis, thereby leading to the aggravation of atherosclerosis. NRF2 activation in macrophages could be a valuable strategy for preventing and treating atherosclerosis.",

Regardless of etiology, persistent inflammation and excessive extracellular matrix (ECM) deposition drive irreversible structural distortion and functional decline in the kidney. Among cellular mediators, macrophages occupy a central role across the continuum from acute injury to fibrosis, orchestrating both tissue injury and repair through dynamic transitions between pro-inflammatory (M1) and pro-fibrotic (M2) states in response to local cues. Here, we synthesize macrophage-driven mechanisms of renal fibrosis, emphasizing recruitment, infiltration, and local proliferation mediated by chemokine-receptor networks and mechanosensitive ion channels. In addition, in this review paper, we provide an overview on the dual roles of macrophages in acute inflammation and chronic remodeling through key cytokine signaling pathways (TLR4/NF-\u03baB, IL-4/STAT6, TGF-\u03b2/Smad, IL-10/STAT3), highlighting how metabolic reprogramming, mechanochemical feedback via Yes-associated protein (YAP)/transcriptional coactivator with PDZ-binding motif (TAZ) signaling, and epigenetic modulators collectively stabilize the fibrotic macrophage phenotype. Also, emerging insights into mitochondrial dysfunction, succinate-succinate receptor 1 (SUCNR1) signaling, and autophagy dysregulation reveal the metabolic basis of macrophage persistence in fibrotic kidneys. Understanding these multilayered regulatory circuits offers a framework for therapeutic strategies that selectively target macrophage-dependent fibrogenesis to halt the transition from acute injury to chronic renal failure.",
"41638907": "ID: 41638907\nTitle: Syk activation during Fc\u03b3R-mediated phagocytosis involves Syk palmitoylation and desulfenylation.\nAbstract: The Syk tyrosine kinase acts downstream of several immune receptors such as the Fc\u03b3R. Syk owns two SH2 domains that interact with biphosphorylated ITAMs of the Fc\u03b3R upon phagocytosis. This results in the activation of Syk by autophosphorylation, triggering phosphorylation of several downstream targets, F-actin polymerization, and phagocytosis of the IgG-opsonized target. We found that Syk is S-acylated upon phagocytosis by macrophages. Palmitoylation is performed on a single Syk-Cys by the DHHC5 enzyme that specifically associates with Syk upon phagocytosis. Syk palmitoylation is important for Syk localization to the phagocytic cup, phosphorylation, and phagocytosis. We observed that another Syk-Cys residue, within a redox motif, is modified by sulfenylation. Nevertheless, Syk desulfenylation seems to occur during phagocytosis, when H2O2 production at the cup decreases, after 3.5 min of phagocytosis. Molecular dynamics studies indicated that desulfenylation increased the exposure of a loop within the Syk interdomain B. This could facilitate phosphorylation of key Syk-Tyr residues by upstream kinases. We thus propose an updated model for Syk activation during Fc\u03b3R-mediated phagocytosis that involves both Syk palmitoylation and desulfenylation.",
"41809010": "ID: 41809010\nTitle: Digest before Ingest: Early Recruitment of Membrane-bound DNaseX to Phagocytic Cups in Macrophages.\nAbstract: Macrophages engulf and degrade pathogens and cellular debris through phagocytosis. The degradation process was generally believed to occur only after phagosome internalization and maturation. Here, we report an early DNase activity at the nascent phagocytic cup (PC) prior to its closure. Using a fluorescent DNase sensor, we revealed rapid and ubiquitous DNase activity upon PC formation across various macrophage types. We further identified the responsible enzyme as the membrane-bound DNaseX, which is constitutively recruited to the PC during PC formation. Although F-actin polymerization is dispensable for DNaseX recruitment, it is essential for its enzymatic activity, likely by promoting physical engagement of DNaseX with solid DNA materials. Functionally, we show that macrophages degrade extracellular DNA (eDNA) within bacterial biofilms through direct physical contact, clearing the eDNA structures without internalization. These findings reveal a previously unrecognized DNA degradation mechanism operating at the macrophage membrane, suitable for degrading bulky eDNA materials which cannot be directly internalized by macrophages.",
"41825123": "ID: 41825123\nTitle: Load-independent ceiling of single-target phagocytic membrane extension revealed by microneedle backtracking assay in macrophages.\nAbstract: The zipper model describes the ligand-receptor-driven progression of the phagocytic cup during macrophage engulfment. However, whether the maximum engulfment achievable for a single target is altered by prior or concurrent phagocytic events (i.e., intracellular phagocytic load) remains unclear. Here, we used IgG-coated, nondigestible glass microneedles as standardized Fc\u03b3 receptor ligands and defined the single-target engulfment ceiling as the membrane extension length at which backtracking begins. We then tested whether this ceiling changes after macrophages internalize increasing numbers of IgG-coated polystyrene beads. Across cells, the maximum membrane extension on a microneedle was quantitatively unchanged regardless of the number of internalized indigestible beads. Within the same cell, additional bead ingestion - up to the maximal bead-phagocytosis limit - did not measurably alter the maximum extension achieved on a microneedle. These data establish a load-independent ceiling for single-target engulfment. This invariance suggests that local membrane recruitment and extension are regulated independently of the cell-wide phagocytic burden, supporting a spatially compartmentalized control mechanism that decouples single-target membrane extension from the total intracellular cargo load.",
"41950296": "ID: 41950296\nTitle: A biophysical model of phagocytic cup dynamics: The effect of membrane tension.\nAbstract: Phagocytosis is a fundamental cellular process by which cells engulf external particles, controlled by receptor-ligand binding and actin-driven membrane dynamics. While a number of mathematical models have been developed to describe this process, they often overlook membrane tension, a key physical parameter known to influence membrane deformation and cytoskeletal behaviour. To address this gap, we present an enhanced mathematical model of receptor motion during phagocytosis that explicitly incorporates the role of membrane tension. Further, we introduce a signalling component that is coupled to receptor dynamics via the membrane tension. We find that including tension results in fundamentally different engulfment behaviour, which is slower than that predicted by models without tension. In particular, unlike in the previous version of this model, we show that tension can lead to stalled engulfment, an experimentally-observed phenomenon known as frustrated phagocytosis. We also find that signalling is able to modify engulfment behaviour, especially at later stages, and is able to alter cup growth to become linear in time without the need for receptor drift as introduced in previous models. These findings offer new insights into the role of membrane tension and biophysical regulation in phagocytosis, with implications for immune function, cell motility and targeted drug delivery.",
"42088827": "ID: 42088827\nTitle: Targeting microglia microtubules: cytoskeletal remodeling as a druggable hub in neuroinflammation and neurodegeneration.\nAbstract: Microglia dynamically remodel their cytoskeleton to surveil the brain, respond to injury, and shape synaptic connectivity. While actin drives rapid process motility and phagocytic cup formation, emerging evidence indicates that microtubules are critical regulators of microglial morphology, trafficking, and inflammatory signaling. In homeostatic microglia, microtubules are nucleated at Golgi outposts, supporting ramified architectures and low inflammatory tone. Upon activation, microglia undergo a switch to a centrosome-nucleated, radial microtubule array, driven in part by cyclin-dependent kinase 1 (Cdk1) and associated with polarized cytokine release, NLRP3 inflammasome engagement, and altered phagocytic behavior. We discuss how key regulators of this transition-including Cdk1, centrosomal \u03b3-tubulin recruitment, Golgi-derived microtubule nucleation, and the kinase MARK4 may constitute druggable nodes to tune microglial reactivity in neuro-degenerative diseases. Finally, we outline experimental priorities for translating microglial microtubules into therapeutic targets.",
"42094351": "ID: 42094351\nTitle: Myo1e/f regulate phagocytic podosomes to promote efficient cup closure in macrophages.\nAbstract: Phagocytosis requires coordinated remodeling of the actin cytoskeleton to generate protrusive and contractile forces that drive target engulfment. Class I myosins Myo1e and Myo1f (Myo1e/f) have been implicated in linking the plasma membrane to the actin network, but their specific roles during Fc-receptor-mediated phagocytosis remain unclear. Using CRISPR-edited RAW 264.7 macrophages lacking Myo1e and Myo1f, we show that double knockout (dKO) cells exhibit markedly reduced uptake of IgG-coated beads, a phenotype that is partially rescued by re-expression of either myosin. Lattice-light-sheet and confocal imaging revealed distinct F-actin architectures corresponding to the various stages of cup progression, including basal podosome-like adhesions, individual phagocytic podosomes (actin teeth) along the rim of the cup, and a contractile phagocytic ring formed by the reorganization of podosomes into a higher-order network. In Myo1e/f-deficient cells, podosome formation was diminished, actin teeth were largely absent, and the phagocytic ring formed prematurely, which was often accompanied by stalled cup progression and repeated engulfment attempts. Myo1e/f localized both to podosomes and to the inner surface of the phagocytic ring, non-muscle myosin II (NM2) localized to the outer surface, and the absence of Myo1e/f correlated with the diffuse distribution of NM2. In addition, Myo1e/f-deficient macrophages exhibited increased trogocytosis of antibody-opsonized HL-60 cells, indicating a shift from whole-target engulfment toward partial target ingestion. These results suggest that Myo1e/f coordinate spatial and temporal transitions between protrusive and contractile actin networks, thereby ensuring efficient phagocytic cup progression. Our findings highlight a dual role for Myo1e/f in adhesion regulation and force balance during macrophage phagocytosis.",

The chapter details its significance across both innate and adaptive immunity, including T cell activation and migration, macrophage polarization, dendritic cell activation, natural killer cell cytotoxicity, neutrophil extracellular trap (NET) formation, and B cell antigen discrimination and class-switching to IgA. PIEZO1 emerges as a central regulator that fine-tunes immune responses by integrating signals from the cellular microenvironment, influencing inflammation, pathogen clearance, and metabolic reprogramming. Despite these advances, key questions remain regarding its role in chronic disease, autoimmunity, and cancer immunity.

In this study, SFC were isolated and identified in vitro, and their\u00a0proliferatives\u00a0and anti-apoptotic properties were examined. Additionally, an early OA inflammatory environment was successfully simulated in cell experiments, demonstrating that inflammatory conditions reduce stemness-associated marker expression in SFC, activate multiple inflammatory pathways, and promote MMP3 expression. When SFC were subjected to cyclic mechanical stretching under inflammatory conditions, increased expression of the mechanosensitive channel Piezo1, enhanced calcium-associated mechanotransduction sensitivity, and disruption of the cytoskeleton were associated with aggravated catabolic responses and apoptosis under inflammatory mechanical stimulation. These findings elucidate the role of SFC in early OA pathogenesis and provide insight into early OA pathogenesis and suggest potential directions for mechanism-based intervention.",

Despite significant advances in reperfusion strategies and pharmacotherapy, persistent inflammation and adverse ventricular remodeling continue to underlie poor long-term clinical outcomes. Macrophages serve as central orchestrators of post-MI healing, coordinating the clearance of necrotic debris, resolution of inflammation, remodeling of the extracellular matrix, and maturation of the fibrotic scar. However, the conventional M1/M2 dichotomy fails to fully capture the dynamic, phenotypically heterogeneous, and metabolically constrained macrophage states that emerge during infarct healing. In this review, we synthesize current evidence supporting a trajectory-based framework for macrophage reprogramming following MI and emphasize mitochondrial fitness as a critical determinant governing the transition from sustained inflammation to reparative resolution. We summarize key metabolic checkpoints regulating this functional shift-including glycolytic rewiring, tricarboxylic acid (TCA) cycle remodeling, mitochondrial reactive oxygen species (mtROS) accumulation, efferocytosis, oxidative phosphorylation (OXPHOS), fatty acid oxidation (FAO), and mitochondrial quality control. Furthermore, we advance the hypothesis that SIRT3-the principal mitochondrial NAD+-dependent deacetylase-may act as a central regulatory node linking mitochondrial protein acetylation to macrophage state transitions after MI. Specifically, we outline a staged dual-axis working model, generated from convergent but largely indirect evidence, in which the SOD2-mtROS axis is more closely linked to early nonresolving inflammation, whereas the PDHA1-metabolic flexibility axis may be more relevant to efferocytosis-associated reparative transition. We further highlight NAD+ availability as an upstream limiting factor that may constrain SIRT3 activity in macrophages under ischemic-inflammatory stress. Finally, we critically evaluate the current evidence hierarchy, human translatability, therapeutic strategies, and key translational challenges-emphasizing considerations of timing, cellular specificity, delivery modalities, and target engagement. Although macrophage-specific causal evidence in myocardial infarction (MI) remains sparse, this framework is intended as a mechanistically coherent and experimentally tractable working hypothesis to guide future investigations into macrophage immunometabolism and mitochondrial-targeted interventions in post-infarction cardiac repair. Accordingly, the proposed framework should be viewed as a testable working hypothesis rather than a settled causal model of macrophage fate control in MI.",

This narrative review synthesizes preclinical and early clinical evidence on the mechanisms and therapeutic applicability of SFN in ICU-acquired weakness, diabetic myopathy, sarcopenia, and exercise-induced muscle damage. SFN modulates skeletal muscle pathophysiology through four interconnected axes: regulation of protein homeostasis via mTOR-associated signaling and suppression of ubiquitin-proteasome-mediated catabolism; upregulation of oxidative stress defenses through Nrf2-driven antioxidant enzyme induction; attenuation of inflammatory networks via NF-\u03baB inhibition and promotion of M2 macrophage polarization; and metabolic reprogramming through AMPK-mediated mitochondrial biogenesis and enhanced insulin sensitivity. Preclinical data suggest preliminary protective effects on respiratory and locomotor muscle; however, clinical translation remains uncertain. Several randomized controlled trials have failed to demonstrate significant effects on Nrf2 target genes or metabolic stress biomarkers, and bioavailability varies markedly across formulations and individuals. Heterogeneous responses across muscle fiber types, an undefined therapeutic window, and interindividual variability in gut microbiota-mediated conversion further complicate clinical application. To address these challenges, we propose a conceptual \"Sulforaphane Precision Medicine Framework\" integrating molecular biomarkers, gut microbiome profiling, and dynamic delivery systems to guide personalized intervention. While SFN shows promise as an adjunctive therapy, standardized formulations, refined patient stratification, and rigorous phase III trials are essential before routine clinical adoption can be recommended.",

One of the primary reasons of RSA is abnormal immunological circumstances at the interaction between mother and fetus. Emerging evidence highlights the critical role of immune dysregulation, particularly involving macrophages, in the pathogenesis of RSA. Macrophages, key immune cells in the decidua, exhibit phenotypic plasticity and can polarize into pro-inflammatory M1 or anti-inflammatory M2 subtypes, thereby influencing trophoblast invasion, placental development, and immune tolerance. How the immune system's macrophages balance impacts an embryo's development is therefore essential to study. This review elaborates on the mechanisms by which alterations in transcription factors, signaling pathways, cytokine profiles, epigenetic status, and metabolic reprogramming contribute to pregnancy loss. Such aberrations predominantly drive the polarization shift toward the M1 macrophage phenotype, characterized by an elevated M1/M2 ratio. This imbalance triggers excessive secretion of pro-inflammatory cytokines, impairs trophoblast invasion, and disrupts placental angiogenesis, thereby ultimately inducing adverse pregnancy outcomes and spontaneous abortion. By integrating findings from human studies and animal models, this review aims to provide insights into the immune mechanisms underlying RSA and highlights future research directions for improving clinical outcomes.",

Here, we developed a hyaluronic acid-modified polypyrrole-copper nanoparticle (PLGA-Cuppy@HA, mCuppy) for copper delivery and irreversible electroporation (IRE)-assisted therapy. To optimize therapeutic performance, copper loading and HA surface modification were systematically tuned, resulting in a formulation with balanced physicochemical properties, efficient CD44-mediated cellular uptake, and favorable biological activity. When combined with IRE, mCuppy exhibited enhanced intratumoral retention, improved 3D spheroid penetration, and increased intracellular uptake, which were associated with IRE-induced membrane permeabilization and improved intratumoral distribution. Mechanistically, integrated transcriptomic and metabolomic analyses revealed that the combination treatment induced profound metabolic reprogramming associated with cuproptosis, including dysregulation of pantothenate/CoA biosynthesis, unsaturated fatty acid metabolism, and glycerolipid metabolism. These alterations were accompanied by lipoylated protein aggregation, lipid droplet accumulation, and mitochondrial dysfunction. Notably, additional analyses of cell death pathways suggested that, while cuproptosis represents a dominant mechanism, apoptosis and lipid metabolism-associated stress responses may also contribute to the overall therapeutic effect. In orthotopic PDAC models, mCuppy combined with IRE achieved marked tumor suppression and promoted antitumor immune remodeling, including dendritic cell maturation, increased CD8+ T-cell infiltration, and M1 macrophage polarization. Together, this study demonstrates that IRE-potentiated copper nano therapy induces metabolic vulnerability, cuproptosis, and immune remodeling in PDAC, providing a promising strategy for stromal-rich pancreatic cancer.",

SPMs are novel potent lipid mediators that play an important role in maintaining inflammation homeostasis and macrophages' functional plasticity. This review will look into the potential function of SPM-programmed macrophage reprogramming as a novel therapeutic strategy for asthma. Unlike current anti-inflammatory treatments, which only focus on suppressing inflammation, SPMs can actively drive the inflammation resolution phase by promoting efferocytosis and wound healing while maintaining the defense against infection. In experimental asthma animal models, lipoxins, resolvins, protectins, and maresins have been demonstrated to alleviate inflammation and airway hyperresponsiveness, shift macrophages towards pro-resolving phenotypes and thus facilitate the resolution process. Levels of some SPM subclasses were found to be reduced in severe or uncontrolled asthmatics, indicating defective resolution pathways may contribute to asthma persistence. The mechanisms include down-regulation of pro-inflammatory cytokines, alteration of macrophage phenotype, improvement of immune homeostasis in the airway milieu, etc. These molecules have become highly promising therapeutic agents after the development of metabolically stable analogs, receptor-targeted agonists, and an improved delivery system. Multi-omics studies coupled with patient stratification based on biomarkers will potentially help in the future to develop personalized resolution-based therapy, in particular for those steroid-resistant and non-type 2 asthmatics. Nevertheless, the evidence provided so far is mainly preclinical; more challenges in terms of pharmacokinetics, formulation and formulation development, regulatory agency approval, and clinical validation remain and will be overcome through further studies, thus warranting investigation into SPM-mediated strategies for asthma and other chronic inflammatory diseases.",

While the irreversible fibrosis of late-stage silicosis has been extensively studied, the cellular and molecular mechanisms by which SiO2 reprograms macrophage metabolism to drive early pathogenesis remain poorly understood. To elucidate this early immune-inflammatory response, we combined targeted metabolomics, pharmacological treatments, and nutrient deprivation in murine alveolar macrophages. Our results demonstrate that SiO2 exposure severely impairs the master antioxidant regulator, nuclear factor erythroid 2-related factor 2 (Nrf2), triggering excessive reactive oxygen species (ROS) accumulation and upregulated glutamine catabolism to drive pro-inflammatory M1 macrophage polarization. We demonstrated that Nrf2 activation with tert-butylhydroquinone (TBHQ) redirected glutamine metabolic flux from pro-inflammatory catabolism to antioxidant anabolism, significantly attenuating SiO2-induced M1 polarization. Conversely, Nrf2 inhibition via ML385 exacerbated the inflammatory response. Furthermore, introducing a glutamine deprivation (-Gln) model revealed that restricting glutamine availability significantly attenuated the ability of Nrf2 to reverse M1 polarization, suggesting that its immune-protective effects largely depend on an intact glutamine metabolic pathway. Ultimately, our findings underscore the severe risks of silica exposure and identify the Nrf2-glutamine metabolic axis as a promising target, providing novel mechanistic insights and a robust basis for \"antioxidant-metabolic\" dual-target interventions in early-stage silicosis.",

However, crystal burden alone does not fully explain asymptomatic crystal deposition, recurrent flares, or the self-limiting nature of acute inflammation. Immunometabolism provides a useful perspective for understanding these differences. In macrophages, glycolysis supports pro-IL-1\u03b2 expression and inflammatory mediator production, while tricarboxylic acid cycle remodeling, mitochondrial stress, and reactive oxygen species may contribute to inflammasome activation. In neutrophils, glycolysis sustains rapid effector functions, including chemotaxis, degranulation, ROS production, and neutrophil extracellular trap formation. During later stages, efferocytosis, lipid mediator switching, and mitochondrial adaptation may promote inflammation resolution. Systemic metabolic abnormalities may further influence recurrence susceptibility by altering innate immune responsiveness to MSU crystals. This review summarizes current evidence linking immunometabolic pathways to gouty inflammation and discusses remaining questions regarding cell specificity, temporal sequence, causal relevance, and therapeutic translation.",
"42520678": "ID: 42520678\nTitle: Dual role of macrophage heterogeneity in allergic inflammation: from mechanism to targeted therapy.\nAbstract: Allergic inflammation, such as allergic asthma, allergic rhinitis, and atopic dermatitis, shares many pathogenic hallmarks, including inappropriate activation of type 2 immune responses, tissue barrier dysfunction, and disruption of local homeostasis. Due to their remarkable plasticity and tissue adaptability, macrophages are crucial effector cells of the innate immune system that play complex, context-dependent dual roles in allergic inflammation. On the one hand, macrophages are implicated in the persistence of chronic inflammation, thereby boosting Th2 cell recruitment, eosinophil infiltration, antigen processing, chemokine secretion, inflammatory mediator release, and tissue remodeling. On the other hand, they promote the resolution of inflammation by triggering barrier repair, producing anti-inflammatory mediators including TGF-\u03b2 and IL-10, and phagocytosing apoptotic cells. Recent single-cell transcriptomic and functional studies have demonstrated that macrophages are dynamically distributed along an activation continuum rather than merely fitting into the traditional M1/M2 polarization. Functional states are determined by cellular origin, illness stage, tissue niche, and complex regulatory networks. For macrophages implicated in airway inflammation and remodeling, non-IgE-dependent nasal neurogenic reflexes, skin barrier disruption, itch neuroimmune circuits, and inflammation resolution, distinct barrier tissues-such as the lung, nasal mucosa, and skin-show notable tissue specificity. The pathogenic and preventive functions of macrophages in allergic inflammation are systematically summarized in this review, which also emphasizes a continuous spectrum of macrophage activation and incorporates interactions among metabolic reprogramming, pyroptosis, epigenetic control, and trained immunity. Given the dynamic and microenvironment-dependent nature of macrophage function, future treatment approaches need to shift from broad anti-inflammatory therapies to precision reprogramming that is stage-specific and tissue-tuned. During the start and amplification stages of inflammation, therapeutic strategies should target pathogenic M2a-like programs, chemokine networks, monocyte recruitment, and excessive pyroptotic responses. On the other hand, M2b/M2c and pro-resolving macrophage-mediated efferocytosis, immunological tolerance, and tissue healing should be the focus of tactics in the resolution and repair stages. Furthermore, the management of allergic diseases may shift from empirical anti-inflammatory therapy to mechanism-guided precision interventions through patient stratification based on single-cell omics, spatial omics, and macrophage-associated biomarkers.",
"42520682": "ID: 42520682\nTitle: Myeloid Piezo1 improves inflammation resolution and phagocytosis in acute liver injury.\nAbstract: Acetaminophen (APAP)-induced acute liver injury (AILI) is characterized by extensive cell death and sterile inflammation, with substantial accumulation of myeloid cells in necrotic areas. Macrophages are critical elements in acute hepatic inflammation and resolution. Piezo1 is a mechanically activated ion channel that modulates innate immune responses and senses microenvironmental cues. The functions of myeloid Piezo1 in AILI remain elusive. This study aimed to determine whether myeloid Piezo1 regulates inflammation resolution and macrophage-mediated clearance during AILI. To generate the AILI mouse model, APAP was administered intraperitoneally to Piezo1fl/fl and Piezo1\u0394LysM mice, and samples were collected at 6, 24, and 48\u00a0h after treatment. Bone marrow-derived macrophages (BMDMs) were stimulated with APAP-treated normal mouse liver cell line (AML12) supernatant to mimic sterile inflammatory response. Liver histology, immunostaining, gene expression analysis, flow cytometry, intracellular Ca2+ measurements, and phagocytosis/efferocytosis assays were performed. Piezo1 exerted protective effects against hepatotoxin-induced liver necrosis and promoted liver recovery after APAP overdose. In vitro assays revealed that Piezo1 alleviated the inflammatory response in bone marrow-derived macrophages. Mechanistically, myeloid Piezo1 manifested a more reparative phenotype and enhanced phagocytic activity by upregulating MerTK expression. Specifically, Piezo1 acted through Ca2+ influx to regulate the expression of MerTK at the target binding stage. Inhibition of MerTK induced more pro-inflammatory mediators and reduced phagocytic ability, phenocopying the Piezo1 deficiency. Separately, Piezo1 modulated cytoskeletal rearrangement via the FAK/Rac1 axis during target internalization. Pharmacological activation of Piezo1 promoted pro-resolution marker expression and enhanced efferocytosis/phagocytic clearance in vitro. This study identified myeloid Piezo1 as an important regulator of macrophage-mediated inflammation resolution and dying-cell clearance during AILI, providing a basis for future exploration of Piezo1-related pathways in macrophage-mediated liver recovery.",

This study tested the hypothesis that age and exercise training alter the response of the HPA axis, insulin, and glucose during an acute exercise challenge to fatigue. Six old (22.0 \u00b1 0.7 years) and six young adult (7.3 \u00b1 0.6 years) unfit Standardbred mares were tested. Mares ran a graded exercise test before (GXT1) and after (GXT2) 8 weeks of training (\u223c60% of HRmax, 3 days/week). Data was analyzed using mixed-effects models with significance of fixed effects determined by ANOVA. There was a significant effect of training on plasma glucose, with higher concentrations during GXT1 vs. GXT2 (P = 0.01), but there was no effect of age. Young horses had lower plasma insulin concentrations than old horses during GXT2 (P = 0.005), but not during GXT1. Age or training did not significantly affect plasma cortisol concentrations, but plasma ACTH was higher during GXT2 vs. GXT1 (P = 0.03), with no effects of age. At VO2max, the relationships between ACTH and cortisol were negative during GXT1 and positive during GXT2 for both age groups; however, these findings were not statistically significant. Training, but not aging, alters horses' ACTH and glucose responses to acute exercise. Aging affects horses' insulin response during acute exercise after training, with young horses having lower insulin responses post training than old horses.",

Herein, we developed a near-infrared (NIR)-activated porphyrin polymer (PTCPP) for photodynamic therapy of CIED infections, which achieves a 100% antibacterial rate with a 22% increase in anti-biofilm efficacy compared to porphyrin (TCPP) in vitro. In diabetic rats, a 93% bactericidal rate is further demonstrated by PTCPP, along with a 97% reduction in the levels of pro-inflammatory factors. It is found that singlet oxygen (1O2) and hydroxyl radicals (\u2022OH) are the main reactive oxygen species (ROS), which can eliminate methicillin-resistant Staphylococcus aureus by disrupting mature biofilms. The immunomodulatory effect of PTCPP stems from dynamic regulation of macrophage polarization. Under irradiation, ROS induce M1 activation to eliminate pathogens, followed by metabolic reprogramming that promotes healing-conducive M2 polarization, thereby accelerating tissue repair. This work showcases the great potential of synergistic photodynamic-immunomodulatory strategies for the next-generation prevention of complex implant-related infections.",
"42522759": "ID: 42522759\nTitle: Metabolomics Effects of Folding Correction in Retinitis Pigmentosa Rhodopsin Mutant P23A.\nAbstract: Retinitis pigmentosa (RP) is a hereditary retinal degeneration disorder often caused by mutations in the rhodopsin gene, leading to photoreceptor death and vision loss. While structural misfolding of rhodopsin is a known contributor to disease pathology, the mechanisms of its cellular and in particular metabolic consequences are poorly understood. To study the direct effects of rhodopsin misfolding and structural rescue on cellular metabolism, we used the P23A mutant and its N2C/D282C stabilized counterpart as a structural tool to assess how differences in folding stability relate to measurable changes at the metabolite level. The engineered cysteine pair allows the formation of a disulfide bond restoring structural integrity and reinforcing the stable seven-transmembrane bundle. We used untargeted Gas Chromatography-Mass Spectrometry (GC-MS) metabolomics analysis conducted in inducible rhodopsin-expressing cell lines, providing a broad and general profiling of metabolic pathway alterations in response to the expression of RP mutants and their structurally rescued counterparts. Principal component analysis, hierarchical clustering, and K-means clustering revealed distinct metabolic signatures associated with each rhodopsin-expressing cell line, demonstrating a highly significant effect of genotype on global metabolite composition (F\u2009=\u200971.679; R2\u2009=\u20090.93724; p\u2009=\u20090.001). Pairwise comparisons and background-subtracted analyses identified consistent alterations in arginine and proline metabolism, glutathione metabolism, and the TCA cycle, nucleotide, amino acid metabolism, redox regulation, and mitochondrial function in cells expressing misfolded P23A. Pathway enrichment highlighted key metabolites in the respective pathways as candidate biomarkers for the rhodopsin P23A mutation. As this study employs a non-retinal cell system, the observed metabolic changes reflect conserved responses to rhodopsin misfolding and proteostatic stress in the ER rather than a direct model of rod cell degeneration. Our findings support the hypothesis that there is a biochemical link, most likely the UPR, between rhodopsin folding/misfolding status and metabolic homeostasis and suggest that targeted metabolic modulation may offer a complementary therapeutic avenue for treating RP.",

This study aimed to investigate the specific mechanism of NR1 against atherosclerosis based on the JAK1/STAT3 pathway. M1 and M2 macrophage models, as well as an ox-LDL-induced macrophage model, were established. These models were treated with varying concentrations of NR1. Our results demonstrated that NR1 effectively suppressed LPS/IFN-\u03b3 or ox-LDL-induced polarization of macrophages toward the pro-inflammatory M1 phenotype and promoted their transition to the anti-inflammatory M2 phenotype. Concurrently, NR1 significantly inhibited the phagocytosis of ox-LDL by macrophages in the atherosclerosis model, reduced lipid accumulation, and improved mitochondrial function. Mechanistically, the regulatory effects of NR1 on macrophage polarization and function primarily depended on the inhibition of the JAK1/STAT3 signaling pathway. In conclusion, this study suggests that NR1 targets the JAK1/STAT3 pathway to balance macrophage M1/M2 polarization, thereby suppressing inflammatory responses, and ultimately alleviating atherosclerosis.",

While the peripheral and cortical representations of taste sensory stimuli are well characterized, far less is known about how metabolic state shapes taste processing in subcortical structures such as the brainstem. The rostral nucleus of the solitary tract (rNTS) is the first central relay for gustatory input, yet how fasting remodels transcriptional programs in rNTS neurons remains poorly defined. To address this gap, we performed cell-type-specific bulk nuclear RNA sequencing of molecularly defined excitatory (Vglut2+ ) and inhibitory (Vgat+ ) rNTS neurons. We combined Cre-dependent Sun1-sfGFP nuclear tagging with fluorescence-activated nuclear sorting to profile each population in ad libitum-fed and 24-hour-fasted mice. The two populations were transcriptionally distinct and differed in their baseline complement of hunger- and metabolic-sensing genes. Fasting elicited a transcriptional response that was largely restricted to excitatory, Vglut2+ , rNTS neurons, while the inhibitory population was minimally affected. In excitatory neurons, fasting reduced the expression of Gabrd, the \u03b4 subunit of the GABAA receptor that mediates extrasynaptic tonic inhibition, while leaving synaptic GABAA subunits and the glutamatergic or GABAergic neurotransmission machinery unchanged. RNAscope in situ hybridization confirmed Gabrd expression in Vglut2+ rNTS neurons and showed that Gabrd is also expressed in the non-Vglut2+ population; the cell-type specificity of the fasting response therefore reflects differential regulation of a shared gene rather than its restricted expression. Our results identify a cell-type-specific, state-dependent transcriptional signature in which fasting downregulates a mediator of tonic GABAergic inhibition in excitatory rNTS neurons, providing a candidate substrate for the metabolic modulation of taste processing within the brainstem.",

LACTB is located in an Alzheimer's Disease (AD) risk locus and its expression in the brain has been genetically associated with AD susceptibility. The aim of this study was to investigate LACTB function and genetic link to AD in myeloid cells, due to their central role in modulating AD risk. Our Mendelian randomization analyses revealed that lower LACTB expression in myeloid cells is genetically associated with reduced disease susceptibility and increased succinylcarnitine, a metabolite independently associated with AD risk. We identified LACTB as a primary enzyme responsible for succinylcarnitine hydrolysis. In human macrophages and microglia, LACTB loss promoted enhanced oxidative phosphorylation, reduced protein synthesis and altered lipid homeostasis. LACTB expression was upregulated following interferon or TNF stimulation, and LACTB loss modified efferocytosis-related functions under inflammatory conditions. In vivo, xenotransplanted human LACTB knockout microglia showed enhanced association with amyloid plaques in the mouse brain. Together, these findings experimentally validated the genetic association between reduced LACTB expression and elevated succinylcarnitine and identified LACTB as an inflammation-responsive regulator of myeloid cell metabolism and function that may contribute to its protective genetic association with AD. Given its druggability and potential to use succinylcarnitine as a genetically-validated endophenotype and target engagement biomarker, LACTB represents a promising therapeutic target for AD.",

In recent years, monoclonal antibodies targeting A\u03b2 have demonstrated encouraging clinical benefits in Alzheimer's disease (AD). However, their therapeutic efficacy remains limited by insufficient and unsustained clearance of A\u03b2, as well as treatment-associated neuroinflammatory responses. These limitations highlight the need for alternative strategies that can achieve efficient A\u03b2 elimination while maintaining immune homeostasis. To overcome these challenges, we developed a novel anti-inflammatory CAR-Microglia (CAR-Mic) incorporating a construct based on the TAM receptor family (TYRO3, AXL, and MERTK), which are key regulators of efferocytosis and anti-inflammatory responses. The resulting A\u03b2-targeted CAR-Mics showed enhanced A\u03b2 engulfment and reduced proinflammatory cytokines release. Among the constructs tested, AXL-CAR demonstrated the most favorable overall performance and was therefore selected for the generation of human induced pluripotent stem cell (iPSC)-derived CAR microglia-like cells (CAR-iMGLs). In an AD mouse model, AXL-CAR-iMGLs exhibited enhanced A\u03b2 clearance without evidence of severe adverse effects. Collectively, these findings establish TAM receptor-based CAR-iMGLs as a promising cell therapy model for AD and potentially other neurodegenerative disorders characterized by chronic neuroinflammation and defective pathological protein clearance.",

Using genetic tools to isolate cilia-specific functions, we found that systemic exclusion of ARL13B from cilia causes hyperphagia and obesity in mice and that ciliary ARL13B is required in the nervous system for weight control. These findings identify ciliary ARL13B as a key regulator of energy homeostasis, contributing to our understanding of how primary cilia act as metabolic signaling hubs.",

These localized microenvironments are shaped by factors such as nutrient availability, hypoxia, acidosis, and immunomodulatory metabolites, all of which strongly influence CD8\u207a T cell infiltration, migration, persistence, and effector function. Growing evidence indicates that spatial metabolic heterogeneity contributes to immune exclusion, T cell dysfunction, and resistance to immunotherapy. This has been accompanied by major advances in spatial metabolomics, particularly mass spectrometry imaging, which now enable the in situ mapping of metabolites within intact tissues. Combined with transcriptomic, proteomic, and imaging-based approaches, these technologies provide unprecedented insight into how metabolism is organized across tumors and how it shapes tumor-immune interactions. In this review, we discuss how metabolic zonation shapes CD8\u207a T cell function across primary tumors and metastatic lesions. We highlight emerging evidence linking localized metabolic programs to T cell exhaustion, impaired motility, and altered immune composition, and discuss therapeutic strategies aimed at improving T cell metabolic fitness, including metabolic modulation and engineering approaches relevant to immune checkpoint blockade and adoptive cell therapies. Finally, we consider the translational potential of spatial metabolomics for biomarker discovery and the development of precision immunometabolic oncology.",

A high regulatory T cell (Treg)/CD8+ T cell ratio and an increased proportion of M2/M1 tumor-associated macrophages (TAMs) in the NEPC tumor microenvironment (TME) are associated with poorer progression-free survival, a phenomenon linked to lipid accumulation within the TME. Understanding the regulatory mechanisms governing both the metabolic and immune landscapes of NEPC is critical. To investigate these mechanisms, prostate cancer cell lines and patient samples were analyzed using immunohistochemistry, flow cytometry, PCR, western blotting, and mass spectrometry. The interleukin (IL)-8/CXCR2 signaling pathway was targeted for intervention in two tumor-bearing mouse models. Data revealed that IL-8/CXCR2 signaling drives the accumulation of free fatty acids and very-long-chain polyunsaturated fatty acids, leading to ferroptosis in tumor-infiltrating CD8+ T cells. This, in turn, promotes Treg cell infiltration and an M2 macrophage-dominant immune landscape. Mechanistically, IL-8/CXCR2 signaling upregulates the AKT-mTOR-FAS pathway while activating the mTOR-MYC-ELOVL5 axis via Rictor acetylation. In preclinical studies using NSG and B57BL/6 mouse models, CXCR2 inhibition restored CD8+ T cell antitumor activity and enhanced TAM phagocytosis, significantly reducing tumor growth. These findings highlight CXCR2 as a promising immunotherapeutic target for NEPC and underscore its relevance in translational medicine.",

This study explored the potential effects of emodin in Yellow River carp (Cyprinus carpio haematopterus). Yellow River carp were used as a model, and multi-omics approaches (including 16S rRNA/ITS sequencing and untargeted metabolomics) were employed, along with evaluations of survival rate, hepatic and intestinal histopathology, quorum sensing-related virulence gene expression, and serum IgM and lysozyme activities. Emodin treatment improved survival rate, alleviated pathological damage in the liver and intestine, downregulated quorum sensing-related virulence genes (AhyR, LapA, AerA), and enhanced serum IgM and lysozyme activities. 16S rRNA/ITS sequencing revealed that emodin increased the relative abundance of Ascomycota, Firmicutes, Debaryomyces and Lactococcus, while decreasing genera such as Bosea and Legionella. Untargeted metabolomics indicated marked changes in metabolic profiles. Correlation analysis revealed that the emodin-enriched microbiota was significantly associated with metabolites and the cytokines il-1\u03b2 and tnf-\u03b1. Emodin treatment was associated with enhanced anti-infection ability in Yellow River carp, concomitant with significant alterations in the intestinal microbiota, metabolism, and immune responses, underscoring its great potential as an environmentally friendly immunostimulant in aquaculture.",
"42529164": "ID: 42529164\nTitle: Gut microbiota and intestinal permeability in rheumatoid arthritis: pathogenic mechanisms.\nAbstract: Rheumatoid arthritis is a chronic systemic autoimmune disease in which the earliest breaks in immune tolerance may arise at mucosal surfaces before the clinical onset of synovitis. Among these sites, the gut has emerged as a particularly compelling candidate because it integrates microbial, epithelial, metabolic, and immune pathways with the potential to shape systemic inflammation. In this review, we examine the biological foundations of the gut-joint axis in rheumatoid arthritis, focusing on intestinal barrier structure, microbiome alterations, mucosal immune crosstalk, and mechanisms of barrier dysfunction. Current human evidence links rheumatoid arthritis to heterogeneous shifts in gut microbial composition, depletion of beneficial metabolite-producing commensals, altered immune-metabolic signaling, and biomarker patterns consistent with epithelial injury and microbial-product translocation. At the same time, available data do not support the existence of a single, universal microbial or permeability signature that defines the disease across populations. Recent longitudinal studies further challenge the concept of stable, long-standing dysbiosis and instead suggest a late, transient phase of ecological instability arising close to symptom onset. Experimental models provide stronger mechanistic support, showing that dysbiotic microbial communities, impaired barrier integrity, and strain-specific host-microbe interactions can promote T helper 17-skewed immunity and aggravate arthritis. Collectively, these findings support a context-dependent contribution of the gut to rheumatoid arthritis pathogenesis while underscoring the need for longitudinal, strain-resolved, and multi-omic human studies to clarify causality, refine disease models, and identify clinically meaningful windows for intervention.",

Beyond their classical roles as immune sentinels, accumulating evidence indicates that IRMs dynamically integrate \u03b2-cell activity, environmental cues, and metabolic stress, thereby coordinating islet homeostasis, adaptive remodelling, and disease progression. However, their context-dependent functions and therapeutic potential remain incompletely understood. This review summarizes current evidence regarding IRM origins, phenotype, metabolic plasticity, and bidirectional crosstalk with \u03b2 cells in health, type 1 diabetes, and type 2 diabetes. We further review emerging therapeutic concepts targeting macrophage metabolism, intercellular communication, and organelle function, while discussing current challenges in translating findings from murine IRMs to human disease. Under physiological conditions, IRMs maintain islet integrity through surveillance, efferocytosis, trophic signalling, redox control, and maintenance of intercellular communication within the islet niche. In diabetes, chronic glucolipotoxicity, autoimmunity, oxidative stress, and amyloid-associated injury can redirect these homeostatic programs toward maladaptive inflammatory states that impair insulin secretion and accelerate \u03b2-cell loss. Collectively, these findings support a unified framework in which IRMs act as immunometabolic hubs integrating local and systemic signals to determine \u03b2-cell fate. IRMs represent central immunometabolic hubs that orchestrate \u03b2-cell fate during health and diabetes. Emerging therapeutic strategies targeting macrophage metabolism, intercellular communication, and organelle function may help prioritize future mechanistic studies and guide safer macrophage-centered interventions for diabetes.",

We previously observed that in such comorbidity settings, macrophages exhibit impaired efferocytosis and reduced anti-inflammatory polarization. In this study, we investigated whether simultaneously restoring these two defective macrophage functions could provide a unified therapeutic strategy both for hepatic and vascular pathology. To establish a comorbidity model featuring concurrent hepatic steatosis and atherosclerosis, we fed ApoE-/-mice a high-fat diet for 14\u00a0weeks. Moreover, we engineered bone marrow-derived macrophages to co-overexpress TGF\u03b21 and MerTK (M\u03c6Smart), thereby restoring anti-inflammatory properties and phagocytic capacity, then treated mice with control macrophages or M\u03c6Smart. TGF\u03b21 and MerTK overexpression in macrophages reprogrammed these cells toward an anti-inflammatory phenotype and endowed them with strong phagocytic capacity under lipid-loaded conditions. M\u03c6Smart reprogrammed macrophage injection into ApoE-/- mice alleviated inflammation locally in the plaque and liver. Consistent with the reduced inflammation, plaques became smaller and more stable after the adoptive transfer of reprogrammed macrophages. Mechanistically, the reprogrammed macrophages alleviated disease manifestations not only via direct inhibition of plaque inflammation but also by reshaping the inflammatory condition in the liver and plaque, where the transferred M\u03c6Smart predominantly accumulated. Macrophage-targeted dual-gene therapy overcomes the limitations of single-target approaches and achieves simultaneous therapeutic efficacy both in the liver and vasculature, establishing a preclinical proof-of-concept for multi-gene synergistic cell therapy in cardiometabolic disease.",

Homocysteine serves as an independent risk factor for atherosclerosis. Here, we developed a synergistic nanotherapeutic strategy for hyperhomocysteinemic atherosclerosis (HHcy-AS) by simultaneously targeting foam cells and diseased macrophages. Specifically, an aggregation-induced emission (AIE) sonosensitizer TTPY-COOH was encapsulated into OPN antibody-modified polymer nanoparticles to form TP-Ab cores, which were then co-loaded with dexamethasone into ROS-responsive platelet membrane-liposome hybrid vesicles, yielding the final nanodrug TP-Ab/Dex@PL. Following intravenous injection, this nanoplatform utilizes platelet membranes to precisely target atherosclerotic plaques, where it rapidly disassembles within the high ROS environments. The released TP-Ab cores selectively deliver TTPY-COOH to foam cells via specific antibody recognition, where subsequent ultrasound-triggered sonodynamic therapy induces cellular apoptosis. Meanwhile, locally released dexamethasone exhibits a robust anti-inflammatory effect and reprograms M1 macrophages into the M2 phenotype, enhancing their efferocytosis for apoptotic foam cells. In an HHcy-AS mouse model, TP-Ab/Dex@PL treatment significantly reduced plaque burden and improved plaque stability. This multifunctional nanoplatform integrates sonodynamic therapy, anti-inflammatory effects, and macrophage reprogramming, offering\u00a0potential\u00a0for the precise clinical treatment of atherosclerosis.",
"42535557": "ID: 42535557\nTitle: Role of Lipin-1 in Macrophage-Mediated Atherosclerosis: Is It Atherogenic or Atheroprotective?\nAbstract: Macrophages are central regulators of atherosclerosis, governing lipid accumulation, inflammatory signaling, and plaque stability. Lipin-1 is a multifunctional lipid-metabolic regulator that integrates cellular metabolism with inflammatory responses through its dual roles as a phosphatidic acid phosphatase enzyme and a transcriptional coregulator. However, its role in macrophage-driven atherosclerosis remains controversial. This review critically evaluates the domain-specific functions of lipin-1 and their impact on disease progression. Accumulating evidence indicates that lipin-1 exerts divergent, domain-dependent effects. The transcriptional coregulatory activity of lipin-1 promotes peroxisome proliferator-activated receptor/peroxisome proliferator-activated receptor \u03b3 coactivator 1-\u03b1 signaling, enhances fatty acid \u03b2-oxidation and oxidative phosphorylation, and supports interleukin-4-driven proresolving macrophage polarization. It also enhances efferocytosis, suppresses sterol regulatory element-binding protein-mediated lipogenesis, and reduces oxidized low-density lipoprotein-induced foam-cell formation. These effects are associated with reduced necrotic core formation, lower interleukin-23 signaling, diminished macrophage necroptosis, and improved plaque stability in experimental models. In contrast, the phosphatidic acid phosphatase enzymatic activity of lipin-1 activates diacylglycerol-dependent protein kinase C-extracellular signal-regulated kinase- activator protein-1 and toll-like receptor 4 signaling, promotes inflammatory eicosanoid production, enhances oxidized low-density lipoprotein uptake, impairs cholesterol efflux, and accelerates foam-cell formation and vascular inflammation. Myeloid-specific loss of phosphatidic acid phosphatase activity reduces lesion size and inflammatory burden while improving macrophage lipid handling. Collectively, current evidence supports a domain- and context-dependent role for lipin-1 in atherosclerosis. The transcriptional coregulatory function appears predominantly atheroprotective, whereas phosphatidic acid phosphatase enzymatic activity is proinflammatory and atherogenic. Selective modulation of lipin-1 activity in macrophages may therefore represent a promising therapeutic strategy to limit atherosclerosis progression while preserving inflammation-resolving pathways.",

As pregnancy progresses and levels of apoptotic placental cells increase, macrophage efferocytosis remains essential to maintain a healthy pregnancy. There is mounting evidence that dysfunctional macrophage efferocytosis is implicated in the pathogenesis of multiple pregnancy complications. This includes disorders of malplacentation such as preeclampsia and fetal growth restriction, wherein impaired spiral artery remodelling and inflammation in the decidua impairs placental vascularisation leading to maternal hypertension, or impaired fetal growth. As a shift in macrophage phenotype and cytokine secretion is required for the onset of labour, alterations in phenotype earlier in pregnancy may be associated with preterm birth. In more rare pregnancy complications such as chronic histiocytic intervillositis (CHI), impaired efferocytosis and wound healing by infiltrating intervillous macrophages may contribute to their excessive recruitment into the intervillous space, hindering placental function. In this review, we describe the importance of efferocytosis by various maternal macrophage populations in the placenta and review the evidence of how impaired efferocytosis contributes to pathology. Furthermore, therapeutic targeting of macrophage efferocytosis and how this may be used to prevent or treat obstetric conditions is explored.",

While bacterial-derived metabolites are increasingly recognized as key mediators, their specific roles in interkingdom crosstalk remain underexplored. Here, we develop a programmable probiotic platform leveraging Lactobacillus gasseri (LG)-tumor metabolic interplay to potentiate bladder cancer therapy. The selected LG strain demonstrates superior tumor-colonizing ability and intrinsic H2O2/lactate biosynthesis, creating an optimal tumor microenvironment for hemoglobin-modified MnOx nanoparticles to enhance chemodynamic therapy efficacy. Mechanistically, microbial metabolites, including L-leucine, orchestrate neutrophil phenotypic reprogramming by suppressing pro-angiogenic dcTRAIL-R1+ neutrophils while activating antigen-presenting CD74+ neutrophil populations. The engineered system elicites coordinated immunomodulation through multiple mechanisms: (1) promoting dendritic cell maturation, (2) increasing CD74+ neutrophil populations, (3) inducing macrophage polarization from M2 to M1 phenotypes, and (4) enhancing tumor infiltration of CD8+ T cells and natural killer cells. This study reveals that bacteria-tumor metabolic crosstalk upregulates beneficial metabolites, notably leucine, which promotes phenotypic reprogramming of neutrophils toward the antigen\u2011presenting CD74+ subset, thereby bridging innate metabolic regulation with adaptive antitumor immunity. This finding goes beyond the material-centric logic of previous probiotic-nanomaterial systems and establishes a metabolism-centric framework for bacteria\u2011mediated cancer immunotherapy.",

However, the direct inhibition effect of AHL on pathogens and the molecular mechanism of inhibition remain unclear. Phytophthora root rot of soybean (PRR), caused by Phytophthora sojae, is a devastating oomycete disease in soybean production. To investigate the application potential of AHL in the PRR control, zoospore chemotaxis, oospore formation, mycelial growth, and pathogenicity in P. sojae responding to AHL were determined. The transcriptome of P. sojae in response to AHL was also analyzed. The key differentially expressed genes (DEGs) were quantitatively verified by qRT-PCR. We found that C10-HSL was the most abundant AHL in the fermentation broth biocontrol strain Pseudomonas mandelii. C10-HSL repels P. sojae zoospores, inhibits P. sojae mycelial growth and oospores formation, and alleviates the pathogenicity of P. sojae. The inhibition effect was regulated mainly by nitrogen metabolism, efferocytosis, glycolysis/gluconeogenesis, carbon metabolism pathways. P. sojae cell structures could disrupt and carbohydrate utilization could interfere during the response process. This result reveals that C10-HSL acts as a cross-kingdom signaling molecule to inhibit P. sojae and control PRR.",

Using water-soluble Au25(o-MBA)18 (o-MBA: o-mercaptobenzoic acids) with optimized local hydrophobicity for weak protein-binding affinity and high endothelium targeting as probes, we report an exosome-mediated systemic clearance for endocytosed nanoclusters in sinusoidal endothelial cells. Au25(o-MBA)18 can effectively avoid phagocytosis by liver macrophage, are initially endocytosed by sinusoidal endothelial cells through clathrin-dependent endocytosis, processed through endosomal pathways, and released as exosomes containing nanoclusters into the bloodstream. During the exosome biogenesis, Au25(o-MBA)18 progressively transform into flower-like aggregates (approximately 100 nm). These circulating exosomes traverse the glomerular membrane through autophagy in glomerular endothelial cells and podocytes before urinary excretion. Here, this exosome-mediated pathway converts exogenous ultrasmall gold nanoparticles into biocompatible endogenous exosome-enveloped cargos for systemic circulation with reduced toxicity, providing a foundation for developing next generation of safe and effective nanomedicines.",

Although its pathogenesis involves multiple factors, the peak incidence of SLE in individuals over 48 years of age points to immunosenescence as a key driver of the disease.Even in younger patients, SLE frequently often presents as premature aging of the immune system. This review synthesizes recent advances in understanding how immunosenescence drives pathogenesis through immune dysregulation across major lymphocyte and myeloid subsets. Within the chronic inflammatory microenvironment, replicative exhaustion of T cells leads to accelerated telomere attrition, persistent activation of the DNA damage response, and telomerase dysfunction. This cascade culminates in the accumulation of senescent T cells displaying a characteristic CD28-CD57+KLRG1+ phenotype, accompanied by a pro-inflammatory state defined by enhanced cytotoxicity and impaired regulatory function. These characteristics correlated directly with disease activity and cumulative organ damage. The process arises from the interplay of metabolic reprogramming and epigenetic remodeling. In parallel, age-associated B cells (ABCs) accumulate, producing high-affinity anti-dsDNA and other autoantibodies, and potentiating inflammation via enhanced antigen presentation. Meanwhile, an aged bone-marrow microenvironment together with clonal hematopoiesis skews monocyte and macrophage polarization toward a pro-inflammatory (M1) profile. These cells show reduced phagocytic capacity and heightened secretion of senescence-associated secretory phenotype (SASP)-like mediators, further driving inflammaging. This review synthesizes current insights into the relationship between SLE risk and immunosenescence. We discuss the mechanisms through which immune aging instigates autoimmunity and explore emerging therapeutic strategies aimed at mitigating immunosenescence.",

To address this translational gap, we have engineered aCD47 - CpG, a novel immune-stimulating antibody conjugate (ISAC) coupling a CD47-blocking antibody (aCD47) to a Toll-like receptor 9 agonist, unmethylated CpG, to enable synchronized deployment of co-stimulatory signals during tumor engulfment. This ISAC, aCD47-CpG, but not the parent aCD47, reprograms macrophages toward an anti-tumor M1-like phenotype, enhances antigen cross-presentation, and promotes robust CD8 + T cell priming. We found that systemically administered aCD47-CpG drove macrophage-dependent tumor suppression in a human lymphoma xenograft model. In parallel, the treatment in immunocompetent syngeneic models of lymphoma and highly immunosuppressive triple-negative breast cancer resulted in profound tumor regression, metastasis inhibition, and durable anti-cancer immune memory. These effects were accompanied by remodeling of the immunosuppressive tumor microenvironment toward an immune-permissive state, characterized by M2-to-M1 macrophage repolarization, intratumoral infiltration of cytotoxic and memory T cells, and depletion of regulatory T cells. This spatiotemporally coordinated immunotherapy platform offers a promising strategy to bridge innate and adaptive immunity, thereby advancing the translational potential of CD47-targeted cancer therapies.",

EVs have emerged as key mediators of this crosstalk; however, their role in sex-specific immune modulation remains incompletely defined. Here, we investigated whether pEVs derived from term placentas induce sex-dependent changes in the phenotype, metabolism, and function of human monocytes. pEVs were isolated from 13 term uncomplicated placentas (six male-derived, M-pEVs, and seven female-derived, F-pEVs) and characterized by complementary approaches, revealing similar size distributions and concentrations, with differences in physicochemical properties and molecular cargo. Circulating monocytes from 17 non-pregnant female donors were exposed to M-pEVs or F-pEVs and analyzed for phenotypic, metabolic, and functional responses. pEVs induced distinct activation profiles depending on fetal sex. F-pEVs reduced CD11b and CD11c expression while increasing CD14, CD39 and IL-10 production. On the other hand, M-pEVs increased CD14 expression and enhanced IL-1\u03b2 secretion. Both nanovesicles populations increased IL-10 and CXCL8 release and promoted a shift toward classical monocytes (CD14+CD16-) with a reduction in the intermediate subsets. Metabolic analyses revealed divergent immunometabolic programs: M-pEVs promoted lactate and reactive oxygen species production, whereas F-pEVs enhanced lactate production, fatty acid uptake, lipid droplet accumulation, and mitochondrial activity without increasing ROS. Functionally, both pEV populations increased efferocytosis, with a distinct sensitivity to metabolic inhibitors. These findings demonstrate that pEVs differentially modulate circulating monocytes according to fetal sex and support a role for fetal sex in shaping maternal immunometabolic responses.",

"42541333": "ID: 42541333\nTitle: NLRC5-Deficient Macrophages Promote a Tumor-Permissive Phenotype via AXL- and MERTK-Mediated Efferocytosis.\nAbstract: The innate immune protein NLRC5 plays a key role in cancer immune surveillance. Reduced NLRC5 expression is associated with a poor prognosis for many types of cancers. Previously, we showed that mice with a myeloid-specific deletion of Nlrc5 (Nlrc5m\u00f8-KO) develop gastric lymphoid lesions to Helicobacter infection resembling early-stage marginal zone lymphoma. We hypothesized that NLRC5 deficiency may promote a tumor-permissive microenvironment mediated by tumor-associated macrophages (TAMs). Consistent with this hypothesis, splenic macrophages from Helicobacter-infected Nlrc5m\u00f8-KO mice had upregulated expression of genes encoding the TAM receptor tyrosine kinases, Axl and Mertk. The levels of AXL and MERTK gene expression and MERTK phosphorylation were increased in NLRC5-/- THP-1 macrophages when compared with WT cells. In response to Helicobacter stimulation, Nlrc5-/- macrophages had significantly elevated anti-inflammatory responses (IL-10, TGF-\u03b2, Socs1, Socs3) compared with WT cells. Importantly, Nlrc5-/-macrophages showed enhanced efferocytosis and reduced antigen presentation to CD8+ T cells. Pretreatment of macrophages with AXL and MERTK inhibitors (R428, UNC2025) resulted in reduced efferocytosis and phosphorylation of downstream signaling molecules, STAT3 and ERK1/2. We propose that defective NLRC5 signaling in macrophages leads to tumor-permissive responses, thereby promoting the development of gastric lymphoid neogenesis to Helicobacter infection.",

While sex-related variation in growth rate and endocrine physiology is well established, much less is known about potential differences in gut morphology, barrier function, microbiota assembly, and intestinal gene expression during the starter period, where early performance divergence between males and females begins to emerge. A clearer understanding of these early-life processes is essential to refine sex-specific nutrition and management strategies. Therefore, this study investigated sex-related differences in gut morphology, intestinal permeability, microbiota composition and predicted functionality, as well as ileal gene expression related to nutrient transport, barrier function, immune response, and metabolic signaling in broilers at 7, 14, and 21\u00a0days of age. Body weight followed a typical early-life pattern and differed between sexes only at d 21, when males were heavier. Gut morphology matured similarly in both sexes, whereas gut permeability declined with age and was lower in males at d 20, suggesting a slightly tighter intestinal barrier. Microbiota structure was predominantly shaped by age, but sex-related divergence emerged with maturation from d 14 onward, especially in the cecum: males were enriched in strict anaerobic fermenters and carbohydrate-degradation/short-chain fatty acid (SCFA)-related pathways, while females showed higher abundance of Romboutsia, Flavonifractor, and other taxa linked to proteolytic metabolism and the degradation of aromatic amino acid-derived compounds. Gene expression was mainly driven by age, yet consistent sex-specific transcriptional signatures were revealed. Males were more associated with nutrient transport (e.g.,\u00a0SLC15A1, SLC30A1, SLC5A1) and epithelial functional maturation profiles (e.g., CDX) over time, whereas females were more associated with tight-junction integrity (e.g., OCLN) and amino-acid sensing/transport markers (e.g., T1R1, SLC3A1). Cecal SCFA concentrations were measured at d 21, yet no differences were found. Overall, gut development was largely age-driven, but sex-specific differences in barrier function, microbiota composition and function, and epithelial gene expression emerged with maturation, without differences in gut morphology or luminal SCFA concentrations.",

RAW264.7 cells were randomly divided into the normal control group, oxidized low-density lipoprotein(ox-LDL) group, HLJDD group, simvastatin(simva) group, and RAW264.7-ERK5 gene knockout(ERK5-KO) group. According to the experimental protocol, cells in each group were treated for 24 h with normal control rat serum, ox-LDL, HLJDD-containing serum, or simva-containing serum. Apoptotic Jurkat cells were added to each group and co-cultured for 90 min. After removal of the supernatant, LC3-\u2161 labeling was performed to observe LAPosomes in macrophages, and the clearance of apoptotic Jurkat cells was assessed. The expression levels of phosphorylated(p)-ERK5, ERK5, LAP-related signaling molecules [T-cell immunoglobulin and mucin-domain-containing molecule-4(TIM-4), vacuolar protein sorting 34(VPS34), Beclin-1, RUN domain Beclin-1-interacting and cysteine-rich domain-containing protein(Rubicon), autophagy-related protein 5(ATG5), and autophagy-related protein 7(ATG7)], pro-inflammatory cytokines [interleukin-1\u03b2(IL-1\u03b2), interleukin-6(IL-6)], and anti-inflammatory cytokines [interleukin-10(IL-10), transforming growth factor-\u03b2(TGF-\u03b2)] were measured. RESULTS:: showed that, compared with the control group, the ox-LDL group exhibited decreased LAPosome percentage and reduced clearance of apoptotic cells, downregulated expression of p-ERK5, TIM-4, VPS34, Beclin-1, Rubicon, ATG5, and ATG7, increased IL-1\u03b2 and IL-6 levels, and no significant changes in IL-10 or TGF-\u03b2 expression. Compared with the ox-LDL group, the HLJDD and simva groups showed increased LAPosome percentage and enhanced apoptotic cell clearance, upregulated expression of p-ERK5, TIM-4, VPS34, Beclin-1, Rubicon, ATG5, and ATG7, decreased IL-1\u03b2 and IL-6 levels, and increased IL-10 and TGF-\u03b2 expression. Compared with the HLJDD group, the ERK5-KO group exhibited significantly reduced expression of ERK5 and p-ERK5, and all other indicators were reversed. In conclusion, HLJDD may ameliorate macrophage LAP dysfunction and exert anti-AS effects by activating ERK5.",

However, these approaches do not adequately address the core drivers of the disease. This limitation arises from an incomplete understanding of the progression from local injury to systemic inflammation and repair, which is a dynamic process with underlying immunoregulatory mechanisms that remain insufficiently characterized. Macrophages are the key effector cells involved throughout the disease course and exhibit pronounced spatiotemporal heterogeneity during this progression. Therefore, they are central to decoding the evolution of the disease and facilitating precise interventions. In terms of spatial dynamics, tissue-resident macrophages (TRMs), which are derived from embryonic sources, and monocyte-derived macrophages (MDMs) recruited from the bone marrow serve functionally complementary roles. Their relative dominance shifts in conjunction with disease progression rather than remaining static. Temporally, the macrophage phenotype undergoes a programmed evolution, beginning with an early phase dominated by M1 proinflammatory responses, transitioning through an intermediate phase where injury and repair coexist, and culminating in a late phase characterized by M2-dominated reparative coordination. This evolution is accompanied by corresponding metabolic reprogramming. Recent single-cell and spatial multiomics studies have unveiled a functional continuum that goes beyond the traditional M1/M2 dichotomy, revealing a rich diversity of cellular subsets and their spatial niches. This insight shifts targeting strategies from broad anti-inflammatory interventions toward more precise modulation aimed at specific phases, subsets, and regions. This review systematically examines the design principles, strengths, and limitations of three classes of intervention-molecular targeting, bioactive natural products, and nanoscale delivery-and identifies the obstacles that continue to impede their clinical translation. Building on this analysis, we propose a dual-dimensional (spatiotemporal) strategy of precise modulation, integrating single-cell and spatial omics, chronobiological principles, and the traditional Chinese medical concept of yin shi zhi yi (adapting treatment to timing), with the aim of shifting AP therapy from symptomatic support toward cause-directed repair.",
"42544579": "ID: 42544579\nTitle: Small molecule inhibitor of orphan GPCR dimerization improves host defense and blood pressure control in mice.\nAbstract: Orphan GPCRs of the GPRC5 family regulate macrophage activity and vascular contractility by dimerizing with other GPCRs, but pharmacological modulation of this process has not been explored. We previously identified the dimerization interface of receptor GPRC5B and show here that both its mutation and inhibition by a decoy peptide disturbed the interaction with the prostaglandin E2 receptor EP2 in macrophages, resulting in reduced EP2 signaling, enhanced migration and phagocytosis, and protection from bacterial peritonitis in mice. Furthermore, we show that a similar interface exists in related receptor GPRC5C, and, the same as in GPRC5B, mutation or inhibition by decoy peptide improved host defense. Through a virtual docking screen, we identified a small molecule inhibitor of both GPRC5B and GPRC5C dimerization, K303MP20, and showed that it reduced EP2 signaling, enhanced macrophage activity, and improved host defense in bacterial peritonitis and influenza A infection. Interestingly, K303MP20 not only blocked dimerization between GPRC5B/C and EP2, but also with prostacyclin receptor IP and angiotensin II receptor AT1, resulting in reduced AT1-dependent contraction and enhanced IP-dependent relaxation in human and murine smooth muscle cells. In vivo, K303MP20 did not affect basal blood pressure, but protected mice from angiotensin II-induced hypertension. Taken together, inhibition of orphan GPCR dimerization by small molecules is feasible and improves infection control and arterial hypertension.",

Their functional plasticity is closely regulated by metabolic reprogramming, particularly glucose metabolism. Glucose-related pathways, including glycolysis, gluconeogenesis, the pentose phosphate pathway, glycogen metabolism, and pyruvate/lactate metabolism, influence TAM polarization, cytokine production, phagocytosis, antigen presentation, and T cell interactions. In many tumors, enhanced glycolysis and lactate accumulation promote M2-like TAM polarization and suppress CD8+ T cell activity, whereas certain metabolic programs may support M1-like anti-tumor functions under specific conditions. This mini review summarizes major glucose metabolic pathways involved in TAM regulation, highlights their context-dependent pro- and anti-tumor roles, and discusses therapeutic strategies for reprogramming TAM metabolism to improve anti-tumor immunity and immunotherapy response.",

Here, we demonstrate that non-invasive and localizable pulsed electromagnetic fields (PEMFs) induce macrophage reprogramming downstream of transient receptor potential canonical 1 (TRPC1) channel activation. Brief (10\u00a0min) PEMF exposure polarized macrophages toward an M1 phenotype by activating Stimulator of Interferon Genes (STING)-dependent NF-\u03baB inflammatory pathways that were abolished by TRPC1 knockdown or inhibition. PEMF exposure directly enhanced the immunogenicity of breast cancer cells and modified macrophage-cancer crosstalk to promote M1 macrophage polarization and the attraction of STING-activated macrophages to the cancer cells. In co-cultures, PEMF exposure stimulated macrophage-mediated phagocytosis of cancer cells in a STING- and TRPC1-dependent manner. In spheroids, PEMFs induced the reprogramming of TAMs to an M1 status and selectively enhanced infiltration of M1 macrophages, resulting in STING-mediated phagocytosis of cancer cells. In mice, 2\u00a0weeks of twice-weekly PEMF exposure resorbed engrafted tumors and selectively eliminated cancer cells within tumors while promoting immune cell recruitment. PEMFs offer a non-invasive manner to locally reprogram TAMs within the tumor microenvironment to preferentially eliminate cancer cells.",

A mouse model of FK was established by the combination of stromal scrapes and corneal contact lens with Fusarium solani. Disease severity was assessed using clinical scoring and histopathological examination. In vitro, bone marrow-derived macrophages (BMDMs) were infected with F. solani, and the efficiency of fungal phagocytosis and escape by BMDMs was determined through fungal counting. The expression of Z\u2011DNA binding protein 1 (ZBP1)-PANoptosis markers in corneal tissues and BMDMs was detected by western blot, and the localization of Z-NAs in these samples was examined by immunofluorescence staining. Additionally, Z\u2011NA expression within in vitro fungal biofilms was detected by immunofluorescence, and its roles in modulating biofilm activity, antifungal drug resistance, and chemotactic ability were further characterized. ZBP1-PANoptosis was significantly activated in FK corneal tissues and positively correlated with clinical severity in FK. F. solani infection triggered Z\u2011NA transformation and ZBP1-PANoptosis activation in BMDMs, which in turn promoted fungal immune escape and exacerbated inflammation. Z\u2011NAs accumulated as extracellular DNA in fungal biofilms and were shown to regulate biofilm activity, drug resistance, and chemotaxis. Z\u2011NAs play a dual pathogenic role in FK by inducing ZBP1-PANoptosis in macrophages and enhancing biofilm function, thereby promoting the progression of FK.",

Here, we investigated macrophage sensing of Debaryomyces hansenii, a food-derived yeast that we found to be enriched within intestinal ulcers of Crohn disease (CD) patients. Using a cell surface receptor antibody screen of bone marrow-derived macrophages infected with a CD patient isolate of D. hansenii, we showed that D. hansenii-induced macrophage activation characterized by increased expression of co-stimulatory molecules, MHC-II, and pattern recognition receptors, including the C-type lectin receptor Dectin-1. Antibody blockade experiments showed both Dectin-1 and complement receptor 3 subunit CD11b were required for phagocytosis of D. hansenii, while Dectin-1 was uniquely required for production of the pro-inflammatory cytokine tumor necrosis factor (Tnf). CRISPR-Cas9-mediated deletion of Dectin-1 phenocopied antibody neutralization effects on phagocytosis. Furthermore, deletion of Dectin-1 or its downstream signaling adaptor molecule Card9 resulted in reduced Tnf secretion in response to D. hansenii. Dectin-1-mediated uptake of D. hansenii was observed in primary bone marrow-derived macrophage and dendritic cells, as well as across the spectrum of macrophage polarization states. Together, these findings define the role of Dectin-1-Card9 signaling axis in innate immune cell sensing of D. hansenii.

The ability of the fungus to cause disease depends on key cell-surface features, such as a polysaccharide capsule that protects it from the mammalian immune system. However, the mechanisms by which C. neoformans traffics polysaccharide capsule, melanin, and other materials to the cell surface are poorly understood. In this study, we employed mutants lacking specific subunits of the adaptor protein complex 1 (AP-1) to investigate its role in the elaboration of virulence-related materials at the cell surface. Importantly, the mutants displayed multiple defects, including alterations in capsule size and cell morphology, and defects in melanin production and urease secretion.

The mechanisms of cryptococcal trafficking of virulence factors during disease are incompletely understood. Adaptor protein (AP) complexes play crucial roles in intracellular trafficking by orchestrating the sorting of macromolecular cargo and serving as essential components of the endocytic and secretory pathways. In a recent study, we demonstrated that Cryptococcus neoformans cells lacking the AP-1 complex subunits exhibit impaired elaboration of virulence factors and fail to survive in the harsh conditions of the macrophage phagolysosome. Although we characterized the phenotypes of AP-1 deficient cells in vitro, the contribution of this complex to pathogenesis remains unexplored. In this study, we show that mutants deficient in AP-1 complex subunits are either avirulent or exhibit attenuated virulence in a murine inhalational model. Loss of the small subunit resulted in the formation of granuloma-like lesions in mouse lungs with early containment of infection but eventual mortality, whereas mutants lacking the large subunits were rapidly cleared by mice. The delayed onset of disease in mice caused by mutants lacking the small subunit was marked by delayed weight loss and increased respiration rate, yet the mutant exhibited enhanced dissemination during late-stage infection, coinciding with waning immune responses and elevated collagen deposition. These findings demonstrate that deficiencies in the AP-1 complex impair C. neoformans virulence, reveal distinct roles for individual subunits, and identify the complex as a potential target for therapeutic intervention in cryptococcosis.",

Currently, there are few approved clinical therapies that specifically target white matter repair to enhance functional recovery after stroke. We demonstrated that microglial adenosine 2A receptor (A2AR) is essential for spontaneous white matter regeneration after ischemic injury in mice. Deletion of A2AR in microglia specifically impaired chronic-phase repair without altering the severity of acute ischemic injury. Pharmacological activation of A2AR signaling with blood-brain barrier-permeable agonistic micelles during the early reperfusion phase enhanced white matter structural repair and led to sustained improvements in cognitive and sensorimotor function in mice. Mechanistically, A2AR activation promoted microglial efferocytosis of apoptotic cells and myelin debris in the lesioned white matter, thereby limiting secondary necrosis-induced inflammation, enhancing neurotrophic factor release, and establishing a reparative microenvironment conducive to oligodendrocyte precursor cell differentiation and remyelination. Moreover, A2AR signaling engaged HIF1\u03b1-dependent metabolic reprogramming to increase glycolysis, thereby providing the energetic support required for efficient and sustained efferocytosis. Together, these findings identify A2AR as a critical regulator of microglia-mediated white matter repair and a promising therapeutic target for enhancing regeneration after stroke.",

(SLT) against psoriasis. A mouse model of psoriasis was established by topical application of imiquimod (IMQ) cream on the nape and dorsal skin. Mice were randomly allocated into the blank control group, model group, SLT treatment groups (low-, medium- and high-dose), and positive control group, with 6 mice in each group. The administration lasted for 7 consecutive days. The skin lesions and pruritic behaviors of mice were observed. Hematoxylin-eosin (H&E) staining was performed to assess the pathological changes of lesional skin and spleen tissues. Toluidine blue staining was used to detect the alterations of mast cells. Immunofluorescence staining was applied to evaluate the changes of T helper 17 (Th17) cells and neutrophils in lesional skin and spleen tissues. Untargeted metabolomics profiling via ultra-performance liquid chromatography coupled with quadrupole time-of-flight mass spectrometry (UPLC-Q-TOF-MS) was conducted to identify differential metabolites in mouse serum, screen potential biomarkers, and analyze the involved metabolic pathways combined with the Kyoto Encyclopedia of Genes and Genomes (KEGG) database. Enzyme-linked immunosorbent assay (ELISA) was used to determine the content changes of interleukin (IL)-17\u202fA, IL-23, tumor necrosis factor-\u03b1 (TNF-\u03b1), IL-1\u03b2, IL-4, interferon-\u03b3 (IFN-\u03b3), vascular endothelial growth factor (VEGF), histamine (HIS), and 5-hydroxytryptamine (5-HT) in lesional skin tissues. SLT alleviated IMQ-induced psoriasis-like skin lesions and spleen edema in mice. SLT ameliorated epidermal hyperplasia and mast cell infiltration in psoriatic lesional skin, and improved inflammatory cell infiltration in both lesional skin and spleen tissues of psoriatic mice. Meanwhile, SLT regulated the levels of Th17 cells and neutrophils in the above two tissues. A total of 30 differential metabolites were screened out via serum metabolomics analysis, which were mainly enriched in signaling pathways including glycerophospholipid metabolism, fatty acid biosynthesis, biosynthesis of unsaturated fatty acids, dysregulated fatty acid metabolism, and Fc\u03b3 receptor-mediated phagocytosis. In addition, SLT significantly downregulated the contents of IL-17\u202fA, IL-23, IL-1\u03b2, HIS and 5-HT in psoriatic lesional skin. SLT exerts a dual anti-psoriatic effect of anti-inflammation and anti-pruritus by inhibiting immune cells such as Th17 cells and mast cells, thereby downregulating inflammatory factors associated with the Th17/IL-23 axis and pruritogens released by activated mast cells. Furthermore, untargeted metabolomics analysis revealed that the anti-psoriatic mechanism of SLT may be closely related to lipid metabolism disorder, a hallmark pathological feature of psoriasis.",

Here, we investigated the role of microglia-derived TNF in the acute and subacute response to permanent middle cerebral artery occlusion (pMCAO). Tnf expression was transiently upregulated after stroke, becoming significant at 4\u202fh, peaking at 12-24\u202fh, and returning to baseline by 5\u202fdays. In situ hybridization confirmed strong Tnf expression in the infarct and peri-infarct regions. Whole-brain transcriptomic profiling showed that global TNF deficiency reshaped the early post-ischemic response, shifting it from microglia-associated phagocytic and wound-healing pathways toward an interferon-related inflammatory signature. To define the specific contribution of microglial TNF, we used inducible Cx3cr1CreER:Tnffl/fl mice. Microglial TNF deletion had no effect on infarct volume in males at 24\u202fh or 5\u202fdays after pMCAO, but significantly increased infarct size in females at both time points. In both sexes, brain TNF levels peaked at 24\u202fh and were significantly reduced in Cx3cr1CreER:Tnffl/fl mice, confirming microglia as a major source of early post-ischemic TNF. However, downstream consequences diverged by sex. At 5\u202fdays, male Cx3cr1CreER:Tnffl/fl mice showed reduced microglial reactivity and 18\u202fkDa translocator protein (TSPO) signal, with no change in T-cell infiltration, and exhibited increased density of mature oligodendrocytes. In contrast, female Cx3cr1CreER:Tnffl/fl mice displayed enhanced microglial reactivity, increased TSPO binding, higher peri-infarct T-cell infiltration, and reduced oligodendrocyte density and myelin integrity. Together, these findings identify microglial TNF as a sex-dependent regulator of post-stroke inflammation and myelin injury.",

Trained immunity, an emerging paradigm wherein innate immune cells develop a memory-like phenotype through epigenetic and metabolic reprogramming, offers a promising avenue to remodel the immunosuppressive tumor microenvironment. This study investigated whether \u03b2-glucan-induced trained immunity could potentiate antitumor immunity against HCC. We established orthotopic HCC mouse models to investigate the role of trained immunity induced by whole \u03b2-glucan particle (WGP) in the HCC microenvironment, particularly in modulating hepatic apolipoprotein E (APOE)-positive monocytes/macrophages. Transcriptional changes in trained monocytes/macrophages were identified by analyzing single-cell RNA sequencing and bulk RNA-sequencing data from the livers of WGP-treated and control mice. Mechanistic studies were performed using Apoe -/- mice and in situ monocyte/macrophage engineering. Flow cytometry was performed to assess immune cell phenotypes and phagocytosis, while luminescence-based assays were used to evaluate cytotoxic activity. The translational potential was assessed using human monocyte training assays. This study demonstrated that preconditioning with WGP, a trained immunity inducer, increased the accumulation of trained monocytes/macrophages in the liver and suppressed tumor progression in HCC mouse models. Mechanistically, WGP-trained APOE+ monocytes/macrophages exhibited a decrease in lipid accumulation and endoplasmic reticulum stress, thereby enhancing their antitumor function. Genetic deletion of Apoe in monocytes/macrophages abrogated the antitumor effects of WGP, demonstrating that APOE+ monocytes/macrophages are essential mediators of WGP-induced trained immunity. Adoptive transfer of WGP-trained bone marrow-derived macrophages suppressed the growth of HCC in recipient mice. Furthermore, WGP induced trained immunity in human monocytes, leading to enhanced killing of HCC cells. Notably, combination therapy with WGP and anti-programmed death-ligand 1 antibody achieved superior tumor control compared with either monotherapy. These findings identify a critical role for trained APOE+ monocytes/macrophages in WGP-mediated antitumor immunity in the liver. Harnessing WGP-induced peripheral trained immunity represents a novel therapeutic strategy for HCC.",

It is characterized by a progressive dysfunction and loss of retinal ganglion cells. Neuroinflammation has been recognized as an underlying neurodegenerative mechanism of glaucoma in animal models and human post-mortem samples, and targeting neuroinflammation may provide additional means to neuroprotection. Galectin-3, a pro-inflammatory mediator encoded by the LGALS3 gene in humans, holds promise as a treatable target as its pharmacological and genetic inhibition is neuroprotective in multiple models of experimental glaucoma. However, the role of Galectin-3 in glaucoma remains unclear, particularly whether its emergence is a consequence of degeneration, or occurs at earlier time points. To address these knowledge gaps, we labeled IBA1, GFAP, and Galectin-3 in retina sections at early glaucoma stages in the rat bead glaucoma model, and in human retina from glaucoma donors. In the rat, IBA1 volume, but not GFAP, increased at an early, pre-degenerative timepoint. Accompanying this, we identified a significant increase of Galectin-3/IBA1 colocalization compared to control at the same timepoint, supporting the upregulation of Galectin-3 in early inflammation, preceding retinal ganglion cell degeneration in experimental glaucoma. However, a significant increase in Galectin-3/GFAP colocalization compared to control at the same timepoint in the rat additionally associates Galectin-3 production with astrocytes and M\u00fcller glia. This Galectin-3 to M\u00fcller glia relationship was significantly pronounced in human glaucomatous retina, predominating over microglia co-labelling. We further demonstarted that human MIO-M1 M\u00fcller glia in vitro express Galectin-3, but this is not altered in response to glaucoma relevant stimuli (TNF-\u03b1 or mild-metabolic stress from rotenone). Instead, Galectin-3 expression was altered in phagocytosing states from exposure to E. coli particles, brain synaptosomes, or apoptotic neuronal debris. These findings provide further insight into Galectin-3 and gross inflammatory responses in glaucoma pathology.",

Growing evidence indicates that Akkermansia muciniphila, a promising next-generation beneficial microorganism, could help alleviate metabolic disorders. Nevertheless, its strain-specific effects and associated mechanisms require further investigation. Here, we investigated the potential effects of pasteurized A. muciniphila AKK PROBIO in T2DM using db/db mice. Our findings show that pasteurized AKK PROBIO supplementation was associated with lower fasting glucose levels, reduced inflammatory markers, and improved cholesterol balance in db/db mice. Pasteurized AKK PROBIO administration was accompanied by changes in gut microbiota composition, including enrichment of bacterial taxa linked to short-chain fatty acid (SCFA) production, and by increased GLP-1 levels and altered serum metabolites, including 9,9'-di-cis-\u03b6-carotene and l-arginine. These changes were paralleled by reduced hepatic expression of proteins related to the TLR4/MyD88/IKK\u03b1/NF-\u03baB and SREBP2/HMGCR signaling pathways. Taken together, our findings indicate that pasteurized AKK PROBIO ameliorates metabolic disorder and inflammation in db/db mice, accompanied by changes in gut microbial ecology, serum metabolites, and hepatic inflammatory/lipid metabolic signaling.

We previously identified distinct microglial signatures that were enriched in AD donors and associated with amyloid and tau, respectively. Here we generated a snRNAseq dataset from postmortem control and AD cases and analyzed alterations in cell-cell communication pathways that might be relevant to AD pathophysiology. One signaling pathway perturbed in AD cases involved SPP1, and while this pathway was also present in control samples, microglia-microglia SPP1 signaling was restricted to AD donors. Further analyses within microglia-microglia signaling predict AD-specific induction of GAS6-AXL signaling (from inflammatory and ribosomal microglia), and SPP1-ITGAV/ITGB5 signaling (from disease-associated and inflammatory microglia, among others). Together, these findings might in part explain the increased microglia phagocytic profile described in AD. RNAscope confirmed enrichment of SPP1 expressing microglia near amyloid plaques in AD brain tissue samples. These data indicate altered cellular communications between microglia in the AD brain.",

CD3+ macrophages have been identified in both infectious and non-infectious pathologies; however, their origin and signaling mechanisms remain poorly studied, primarily due to their low prevalence in human samples. Utilizing the RAW murine macrophage cell line as a model, this study aimed to ascertain whether nutrient deprivation induces CD3 expression and to identify the signaling molecules involved in the activation of a CD3-dependent proinflammatory profile. Firstly, the impact of environmental stress, specifically nutrient deprivation, on CD3 expression over a period was assessed. Subsequently, RAW cells were stimulated with anti-CD3 and IgG2a, and the profile of proinflammatory cytokines was evaluated alongside the expression of signaling proteins, including NFAT, c-Jun, and IKK. Furthermore, the transcriptional regulation of IRF-1, GATA-3, and MAFB was examined. Lastly, the functional capacity of CD3+ RAW cells was determined through a phagocytosis assay. RAW cells were found to express molecules classically associated with T cells, including CD3, TCR, and CD4. Notably, CD3 expression was significantly upregulated at both the protein and transcriptional levels under nutrient deprivation, although it did not reach the levels observed in T cells. Functionally, CD3+ RAW cells exhibited enhanced phagocytic activity toward latex beads. Furthermore, stimulation with anti-CD3 plus IgG2a induced a robust proinflammatory cytokine response, characterized by the secretion of IFN-\u03b3, TNF, and IL-6 as early as 5 hours post-stimulation. This response was associated with activation of signaling pathways involving NFAT, c-Jun, and IKK, along with increased IRF-1 expression and downregulation of MAFB, supporting the establishment of a CD3-dependent proinflammatory profile in RAW cells. Our findings establish RAW macrophages as a model to study CD3+ signaling machinery in myeloid cells. We demonstrate for the first time that nutrient deprivation induces CD3 expression and that the resulting CD3-driven proinflammatory program is associated, at least in part, with NFAT and IRF-1. These conclusions provide new insights into the origin and functional significance of CD3+ macrophages and offer a valuable platform for investigating the impact of this pathway on innate immune responses across various pathological contexts.",

Gut microbial dysbiosis in sepsis may result from both disease pathophysiology and ICU interventions, including broad-spectrum antibiotics, vasopressors, enteral or parenteral nutrition, mechanical ventilation, renal replacement therapy, immune status, and baseline comorbidities. Increasing evidence suggests that gut microbial dysbiosis is closely associated with sepsis progression and sepsis-associated organ injury, and may act as both a consequence of critical illness and a potential contributor to disease progression in selected experimental and clinical contexts. Host-microbe interactions, microbial metabolites, and immune-metabolic signaling help explain how gut dysbiosis contributes to sepsis pathophysiology. At the same time, probiotics, fecal microbiota transplantation, and selected microbial metabolites have shown possible benefits, mainly in experimental or selected clinical settings. This review integrates gut dysbiosis, microbial product translocation, microbial metabolites, and host-microbe interactions into a gut-organ axis framework, and evaluates how these mechanisms may contribute to sepsis progression, organ injury, and microbiota-targeted therapeutic strategies.",

One such disease is fundus albipunctatus (FA). FA is caused by autosomal recessive retinol dehydrogenase 5 (RDH5) mutations and results in rod dysfunction leading to night blindness and, in a subset of patients, macular degeneration (MD). We previously reported a spontaneous feline model of FA due to an RDH5 missense mutation. The affected cats showed rod dysfunction and a proportion developed degeneration of the area centralis (AC), equivalent to MD in humans. We used fundus confocal scanning laser ophthalmoscopy and spectral-domain optical coherence tomography imaging, six different electroretinography protocols, immunohistochemistry, and histology/transmission electron microscopy to further characterize this large-animal cat model. In addition to rod dysfunction, cone recovery from intense stimulation was impaired. For RDH5-/- cats that developed AC degeneration, an initial elongation of rod outer segments with disorganization of the distal tips was initially detected in the AC and visual streak, suggestive of impaired shedding/phagocytosis. With progression, photoreceptors degenerated in the AC, matching the MD seen in some human patients. The RDH5-/- cat model recapitulates features of both rod and cone dysfunction seen in human patients with RDH5 mutations. The RDH5-/- cat model offers a unique opportunity to further understand the mechanisms of RDH5-associated retinopathies and to investigate potential therapeutic approaches.",

Redirecting monocyte differentiation offers a compelling yet underexplored therapeutic opportunity. In this work, we found M1-polarized macrophage-derived extracellular vesicles (M1-EVs) efficiently induced monocytes to differentiate into anti-tumor macrophages via tumor necrosis factor alpha (TNF-\u03b1)-mediated signaling. Despite promising, the therapeutic efficacy of M1-EVs was constrained by insufficient glioma accumulation and CD47-mediated phagocytic inhibition. To address this challenge, we further engineered M1-EVs with dual-targeting specificity by genetically incorporating a tumor-directed chimeric antigen receptor (CAR) against IL13R\u03b12 or EGFRvIII together with CD47-blocking SIRP\u03b1 variants. The resulting dual-targeting EVs (M1-CS-EVs) exhibited enhanced blood-brain barrier (BBB) penetration and glioma accumulation while locally disrupting CD47-SIRP\u03b1 interactions. In three orthotopic glioma models, M1-CS-EVs elicited a potent anti-tumor immune response and enhanced tumor phagocytosis, significantly suppressing tumor growth while prolonging animal survival. Our findings establish a platform technology for directing monocyte differentiation toward anti-tumor phenotypes, offering a broadly applicable strategy for glioma treatment.",
"42554604": "ID: 42554604\nTitle: Stress Hyperglycemia Drives CD4+ T Cell PANoptosis and Postoperative Organ Injury via Monocyte-Derived Succinate.\nAbstract: Perioperative stress hyperglycemia is a transient but frequent metabolic disturbance strongly linked to postoperative organ injury and mortality; however, the immunometabolic mechanisms driving this association remain largely undefined. In a two-center cohort of patients undergoing total aortic arch replacement, we identify stress hyperglycemia as an independent determinant of poor postoperative outcomes that associates strongly with CD4+ T cell loss. Hyperglycemia induces inflammatory PANoptosis in CD4+ T cells from patients in response to surgical trauma. This results from elevated glucose driving the accumulation and release of succinate from monocytes, which subsequently acts on CD4+ T cells to compromise mitochondrial integrity and activate ZBP1-mediated PANoptosis. Our findings define a monocyte-T cell metabolic signaling axis that transduces hyperglycemic stress via elevated succinate to adaptive immune cell death and reveal potential therapeutic targets to prevent postoperative immune dysfunction and organ injury, especially for patients with hyperglycemic comorbidities.",

However, an emerging body of evidence compels a broader conceptual reframing: ASICs function as dynamic sensors of metabolic state, integrating real-time signals of neural activity, including CO\u2082-derived H+, lactate, and nano-domain pH transients, to regulate neuronal excitability and intercellular communication. Here, we review the mechanisms by which activity-dependent pH shifts arise in the brain, how lactate potentiates ASIC gating through divalent-cation chelation and direct channel modulation, and how the tripartite neuron-astrocyte-vascular unit functions as a spatially organized pH-sensing system. We discuss how astrocytes simultaneously buffer extracellular pH and express ASICs, placing them at the center of a bidirectional metabolic feedback loop, and how ASICs in cerebrovascular cells may link neural metabolic load to vascular tone. Finally, we identify key open questions, including the spatial scale of physiologically relevant pH nano-domains, the role of ASIC tachyphylaxis as a \"use-history\" sensor, and whether ASIC-dependent metabolic signaling shapes circuit-level dynamics during sleep-wake transitions and high-demand cognitive states. This perspective reframes ASICs not merely as damage sensors but as constitutive physiological transducers of brain metabolic activity.",

G protein-coupled receptor 146 (GPR146) has emerged as a pivotal regulator of systemic cholesterol metabolism; however, its role in the central nervous system and AD remains elusive. Here, we report that GPR146 deficiency in mice modulates ERK/PKA signaling without affecting baseline physiology or general behavior. Following intracerebroventricular (i.c.v.) injection of amyloid-\u03b2 (A\u03b2)42 oligomers, GPR146 was associated with altered A\u03b242-evoked ERK/PKA/Akt signaling both in vivo and in vitro. Mechanistically, Gpr146 ablation potentiated microglial A\u03b2 phagocytosis, which correlated with the transcriptional upregulation of phagocytic receptors, including TREM2, GPR34, P2Y6, and CR3, alongside increased expression of pro-inflammatory cytokines (TNF-\u03b1, IL-1\u03b2, IL-6). Moreover, GPR146 deficiency was linked to elevated levels of blood-brain barrier (BBB)-associated markers Cldn-5 and Glut-1 protein levels, while attenuating A\u03b2\u2011induced inflammatory responses in brain endothelial cells. At the metabolic level, GPR146 knockout modulated the expression of key enzymes governing glucose (GLUT1, GLUT3, G6PD, PFK, HK) and lipid (HMGCS1, ACACA, FASN, SCD1) metabolism and markedly reduced A\u03b2\u2011elicited lipid droplet accumulation in the cortex and hippocampus. Collectively, our findings establish GPR146 as a novel neurometabolic regulator whose deficiency correlates with enhanced A\u03b2 phagocytosis, maintenance of BBB-associated proteins, and altered cerebral metabolism, thereby presenting a potential therapeutic axis for early AD intervention.",

Single-cell RNA-seq (ScRNAseq) of the peritoneal macrophages from EMS patient revealed elevated Triggering Receptor Expressed on Myeloid cells 2 (TREM2) and signal regulatory protein \u03b1 (SIRP\u03b1). The expression of TREM2 and SIRPa is positively correlated, and each are positively correlated with estrogen response. Mouse EMS model was established by intraperitoneal injection of estrogen primed mouse endometrial fragments into recipient female mice. In vitro estrogen treatment of RAW 264.7 cells indicated an increasing TREM2/SIRP\u03b1 expression and enhancing phagocytosis of lesion cells derived from WT EMS ectopic lesions. Peritoneal macrophage from mice with EMS were analyzed using flow cytometry for the expression of TREM2 and SIRP\u03b1. The assessment of F4/80, CD206, and SIRP\u03b1 expressing cells within the lesions were performed through the implementation of multi-color immunohistochemistry (mIHC). Small peritoneal macrophages (SpMs, F4/80low CD11blow) were markedly increased in the EMS model. Trem2 knockout mice, as the recipient, showed smaller ectopic lesion size and less lesion formation. TREM2 deficiency inhibited SpM polarization into M2 and downregulated their SIRP\u03b1 expression, while enhancing phagocytic activity. Mechanistically, estrogen pretreatment upregulated TREM2, which correlated with SIRP\u03b1 upregulation and impaired phagocytosis. Under estrogen exposure, TREM2 knockdown RAW 264.7 cells potentiated phagocytosis. Thus, TREM2 is an important contributing pathogenic factor in promoting EMS by enhancing M2 polarization and suppressing phagocytosis via SIRP\u03b1 upregulation.",

Inspired by these bio-geometries, we explore how nanoscale anisotropy can be engineered to control the dynamic transport and biodistribution of synthetic nanocarriers in the body. We fabricate anisotropic silica nanocapsules with precisely tunable asymmetry to dissect shape effects on nano-bio interactions under physiological flow. Under shear flow in vitro, increasing anisotropy markedly reduced cellular uptake, whereas this effect was much less pronounced under static conditions, revealing strong flow-shape coupling. In vivo, highly anisotropic nanocapsules exhibit prolonged circulation, with a 2.8-fold longer half-life than spherical counterparts and significantly reduced sequestration by the liver, spleen, and circulating blood cells. Mechanistic analyses attributed these effects to decreased phagocytic internalization by Kupffer cells, splenic macrophages, and circulating monocytes. Computational fluid dynamics simulations corroborated this phenomenon, demonstrating that greater anisotropy shifts particle trajectories away from vessel walls toward the central flow stream, lowering the chances of cellular interception. Together, these results establish nanoscale anisotropy as a critical determinant of nanoparticle transport, immune recognition, and clearance under flow. Anisotropy engineering therefore provides a nature-inspired framework for designing long-circulating, immune-evasive nanocarriers with improved therapeutic performance.",

One strategy to combat antimicrobial resistance is to modulate host immunity to eliminate infections more effectively. This has led to the development of immunotherapeutics consisting of vancomycin conjugated to formyl peptides (fPeps), with vancomycin targeting the cell wall and the fPeps engaging host innate immunity. Here, we used flow cytometry to quantify the binding of vancomycin=fPep conjugates to S. aureus clinical isolates. This revealed reduced binding of vancomycin=fPeps compared to vancomycin alone and quantified the interaction between the conjugates and the bacterial cell surface, which is important to quantify to then control the chemotactic gradient established by the fPep cargo. The direct antimicrobial activity of these conjugates was also reduced when compared to vancomycin, reflecting the reduced binding of these conjugates to S. aureus.

Post-hepatectomy liver failure remains a major clinical challenge. Objective: This review summarizes metabolic mechanisms underlying liver regeneration and explores metabolic vulnerabilities in patients with HCC, along with emerging therapeutic strategies to enhance regenerative capacity. Methods: A narrative review of current literature was conducted focusing on hepatic regenerative biology, metabolic reprogramming, and clinical metabolic interventions relevant to perioperative liver care. Results: Liver regeneration is regulated not only by growth factor signaling but also by coordinated metabolic reprogramming, including energy metabolism, lipid oxidation, amino acid homeostasis, mitochondrial function, and inter-organ crosstalk. Patients with HCC often exhibit impaired regenerative metabolism. Emerging interventions include nutritional optimization, branched-chain amino acid supplementation, L-carnitine administration, exercise-based prehabilitation, and modulation of the gut-liver axis. L-carnitine is highlighted as a mitochondrial modulator with potential benefits for hepatic function and muscle preservation. Conclusion: Targeting metabolic pathways represents a promising strategy to enhance liver regeneration.

The antibacterial activity of HNST was assessed against Escherichia (E.) coli DH5\u03b1 and Streptococcus (S.) pneumoniae D39 using bacterial growth curve analysis. The immunomodulatory effects were examined in THP-1 monocytes by quantifying phagocytosis via a gentamicin protection assay, cytokine release by enzyme immunoassay and NF-\u03baB activation using the THP1-Blue\u2122 NF-\u03baB reporter cell line. Cell viability was evaluated by microscopy and lactate dehydrogenase (LDH) release assays. The potential for lipopolysaccharide (LPS) contamination was assessed using a Limulus amoebocyte lysate (LAL) assay and validated with the TLR4-deficient THP1-Dual\u2122 KO-TLR4 reporter cell line. HNST exhibited significant antibacterial activity against the Gram-positive strain S. pneumoniae, but not against E. coli. It enhanced phagocytic activity and induced NF-\u03baB activation in THP-1 monocytes in a concentration-dependent manner. Compared to an unstimulated control, HNST moderately increased intracellular killing of bacteria. These effects were independent of its LPS content. No significant cytokine release was detected at non-cytotoxic concentrations. Cytotoxicity was observed at higher concentrations. HNST demonstrated immunomodulatory and selective antibacterial activity, which supports its traditional use as an immune-enhancing agent.

Three-dimensional stem cells (3D SCs) culture systems have emerged as a superior alternative by more accurately mimicking the in vivo microenvironment and enhancing stemness maintenance, regenerative efficiency, and paracrine secretion. However, studies exploring the application of 3D SCs in T1D remain limited. Here, we developed a novel serum- and cytokine-free orbital-shaking system. It enables efficient and large-scale reprogramming of somatic cells into 3D embryonic-like stem cell spheroids (Sph-Es) characterized by robust pluripotency and improved safety. To enhance therapeutic utility, Sph-Es were irradiated and transduced with INS-expressing adenoviral vectors to generate Sph-R-Ins, allowing transient insulin production without permanent genomic modification. In STZ-induced T1D mice, Sph-R-Ins improved glycemic control and glucose tolerance and increased mouse insulin and C-peptide responses, indicating improved endogenous islet function. Donor-cell tracking analyses showed no pancreatic engraftment, supporting an indirect mode of action. Additional transcriptomic, immunological, and ex vivo studies indicated that the therapeutic benefit was accompanied by ECM-related signaling changes, reduced inflammatory infiltration, enhanced M2 macrophage polarization and Treg-associated immune regulation, improved metabolic signaling, and spheroid-derived paracrine support of islet function.

This study characterizes LitCTL1, a novel secreted single-domain C-type lectin from the common periwinkle, Littorina littorea. The 199-amino acid polypeptide contains a conserved carbohydrate recognition domain with canonical QPD and WND motifs and is predicted to form a homodimer. Uniquely, LitCTL1 was localized in both circulating hemocytes and mucus-secreting epithelial cells of the foot, mantle, and hypobranchial gland - the first report of such dual localization for a molluscan lectin, linking systemic and mucosal defense. Expression analysis revealed that LitCTL1 is constitutively expressed in hemocytes. Functional assays with recombinant LitCTL1 demonstrated its role as a potent opsonin with hemagglutinating activity, significantly enhancing hemocyte spreading and the phagocytosis of zymosan. Genomic analysis reveals that LitCTL1 belongs to a rapidly diversifying, genus-specific expansion distinct from conserved perlucin-like lineages. These results identify LitCTL1 as a key effector molecule in both systemic and mucosal innate immunity, likely reflecting an evolutionary adaptation to the microbial challenges of the intertidal environment.",

Despite extensive investigations into itaconate, a prominent immunometabolite implicated in macrophage polarization, the precise mechanisms by which it modulates bone metastasis remain unresolved. Integrating metabolomics and transcriptomics profiling, the molecular landscape of lung cancer bone metastasis is delineated and the mechanistic role of itaconate is uncovered. Further ubiquitination proteomics of tumour cells and CRISPR-Cas9-mediated knockout of the gene encoding immune-responsive gene 1 (IRG1) confirmed the results in an animal model of lung cancer bone metastasis. The macrophage-to-myofibroblast transition generated cancer-associated fibroblasts that secreted elevated levels of itaconate, significantly accelerating tumour growth. A drug affinity responsive target stability screening pinpointed heat shock protein family A member 8 (HSPA8) as a direct molecular target of itaconate. Mechanistically, itaconate promoted HSPA8 ubiquitination and subsequent proteasomal degradation, thereby releasing activated transcription factor 4 (ATF4) from cytosolic sequestration. Liberated ATF4 translocated to the nucleus, where it bound the promoter region of phosphoserine aminotransferase 1 (PSAT1) to upregulate its expression. In vivo validation demonstrated that administration of adeno-associated virus-delivered PSAT1 short hairpin RNA or of a cell-penetrating itaconate antagonist significantly reduced tumour burden and prolonged survival. Our findings elucidate an unappreciated metabolic reprogramming axis in lung cancer bone metastases: macrophage-to-myofibroblast transition-derived itaconate alleviated cytoplasmic sequestration of ATF4 via HSPA8 ubiquitination, thereby activating its transcriptional target PSAT1. This mechanism converts immunometabolic byproducts into pro-tumorigenic signals that enhance bone metastasis. Notably, the HSPA8-ATF4-PSAT1 axis was identified as a key regulatory pathway governing metabolic reprogramming, thereby establishing a translational framework for targeting immunometabolic crosstalk in bone metastasis therapy.",

Upon damage, a regenerative microenvironment forms that provides signalling cues that stimulate stem cell proliferation to replace lost cells. While this process is well understood, how stem cells themselves sense damage, translate this input into their proliferation and shape\u00a0the regenerative microenvironment remains unclear. Here we show that Draper-Src-Shark signalling in Drosophila intestinal stem cells (ISCs) recognises tissue damage by sensing externalised phosphatidylserine on dying midgut epithelial cells and is required for STAT activation in ISCs to promote their proliferation. Unlike its role in phagocytosis, Draper in ISCs does not promote the clearance of these apoptotic enterocytes but rather facilitates ISC proliferation in the presence of damaged enterocytes. Moreover, Draper-Src-Shark signalling in progenitors regulates STAT transcriptional activity in the adjacent visceral muscle, indicating that progenitors can shape the regenerative microenvironment beyond tissue boundaries. As Src and STAT are also activated in the mammalian intestinal epithelium after damage and tumour formation, these findings may help develop therapies for tissue regeneration, inflammatory diseases and cancer.",

The P2X7 receptor performs distinct functions, depending on the extracellular ATP concentration and the duration of exposure to ATP. With brief ATP stimulation, the P2X7 receptor acts as an ion channel, and the movement of ions is associated with the regulation of cell proliferation and differentiation. Prolonged ATP exposure induces a conformational change in P2X7, allowing large molecules to pass through the membrane via the formation of macropores, thereby contributing to cell death. A novel function of P2X7 as a scavenger receptor was recently reported in the absence of both serum and ATP. However, the discovery of non-functional P2X7 in cancer reveals that this group of isoforms of P2X7 fails to form macropores upon ATP stimulation and cannot initiate ATP-induced cell death, allowing malignant cells to evade this regulatory mechanism and continue proliferating. We discuss the multifaceted functions of the P2X7 receptor in regulating diverse cell types, including cell growth, death, and clearance, and how the non-functional form of P2X7 disrupts this balance in cancer. Furthermore, the review explores the potential targeting of this aberrant isoform of P2X7 in the development of novel cancer therapies.",

Macrophages (M\u03c6s) significantly contribute to this process through their scavenger receptor CD36. PIM1 is a serine/threonine kinase known to modulate immune responses and cell metabolism. However, its role in M\u03c6 lipid handling and atherogenesis is not well defined. This study examines the role of PIM1 in regulating CD36 expression and function in M\u03c6s during foam cell formation and atherosclerosis progression. We performed in vitro studies by treating murine peritoneal M\u03c6s from Pim1-/- and wild-type mice with oxLDL (oxidized low-density lipoprotein). We measured CD36, PIM1, and plaque-associated proteins and mRNA levels, oxLDL binding and uptake rates, and foam cell formation. For in vivo studies, we fed myeloid-specific Pim1-deficient (Apoe-/-Lyz2Cre/+Pim1fl/fl) and their littermate control (Apoe-/-Pim1fl/fl) mice a high-fat diet for 12 weeks. We then evaluated plaque formation in their aortic sinuses and arches. Deletion of Pim1 in M\u03c6s reduced CD36 protein expression by up to 96.7% compared with wild-type controls. This led to a 49.6% decrease in foam cell formation and a 25.5% reduction in cellular cholesterol after oxLDL treatment. Pharmacological inhibition of PIM kinase activity in wild-type M\u03c6s also impaired oxLDL handling, with a 64.5% reduction in binding and a 57.9% reduction in uptake. Bulk RNA-sequencing revealed that Pim1 deficiency downregulated PPAR\u03b3 (peroxisome proliferator-activated receptor gamma) signaling. Treatment with a PPAR\u03b3 agonist restored CD36 levels in the Pim1 knockdown M\u03c6s, suggesting that PIM1 regulates CD36 through PPAR\u03b3. Moreover, Pim1 myeloid-specific deficiency caused a 69.4% reduction in atherosclerotic plaque formation. PIM1 acts as a key upstream regulator of CD36 by enhancing PPAR\u03b3 activity in M\u03c6s. The PIM1-CD36 axis promotes oxLDL binding, uptake, and foam cell formation. Targeting the PIM1/PPAR\u03b3/CD36 pathway could offer new ways to modulate M\u03c6 lipid metabolism and reduce atherosclerotic plaque progression.",

These microparticles induce a systemic hypercoagulable state that rapidly transitions into secondary coagulopathy and endotheliopathy. We hypothesize that removing these microparticles from circulation could mitigate the TBI-induced secondary pathologies and improve outcomes. In this study, we investigated the role of Gas-6 (growth arrest-specific 6) as a scavenging factor for microparticles. We quantified plasma Gas-6 levels in a mouse model of TBI and administered exogenous Gas-6 either before or after TBI to evaluate its effects on endotheliopathy, coagulopathy, and outcomes. Mechanistic studies assessed Gas-6-mediated clearance of circulating microparticles in TBI mice and investigated the molecular interactions by which Gas-6 binds microparticles and macrophages to facilitate microparticle scavenging. We found that plasma levels of Gas-6 were significantly reduced in mice subjected to severe TBI. Exogenous Gas-6 given either preinjury or postinjury attenuated coagulopathy, protected the integrity of the cerebral and pulmonary endothelium, improved neurological recovery, and increased overall survival of TBI mice. Gas-6 increased the clearance of anionic phospholipid-expressing microparticles from circulation by coupling microparticles with macrophages and monocytes through the \u03b3-carboxyglutamate and the LG1 (laminin G-like domain 1), respectively, to facilitate phagocytosis of microparticles in the liver. These findings demonstrate the therapeutic potential of Gas-6 for TBI and potentially for other acute pathologies, in which microparticles initiate and propagate coagulation dysfunction and endothelial injuries.",
"42558291": "ID: 42558291\nTitle: IL-33 promotes efferocytosis by peritoneal macrophages by a mechanism associated with rapid granulocyte IL-13 production.\nAbstract: Resolution of inflammation is an active process that requires efferocytosis, the engulfment of apoptotic cells by macrophages, mediated by receptors such as MerTK. IL-33 is an alarmin that initiates type 2 immune responses, including increased production of IL-13, which promotes MerTK expression. The ability of IL-33 to promote efferocytosis in vivo was examined. Intraperitoneal administration of IL-33 to mice increased local MerTK+ macrophage numbers within 48h. MerTK+ macrophages were not similarly induced by free mitochondria, an alternative cell damage associated signal. Efferocytotic activity was increased rapidly in response to apoptotic thymocytes in IL-33-treated mice. The established inducer of MerTK expression, IL-13, was detected in peritoneal lavage fluid shortly after IL-33 administration. Peritoneal eosinophils expressed the IL-33 receptor and demonstrated both intracellular IL-13 by flow cytometry and significantly increased Il13 transcript expression following IL-33 treatment. In contrast, neither elevated IL-13 expression nor IL-13 protein secretion was observed in peritoneal lymphocyte populations within the first 6 hours after IL-33 administration. Primary cultures of bone marrow-derived mouse mast cells and eosinophils demonstrated IL-13 protein responses to IL-33 administration within 6\u00a0h. Mast cell-deficient Cpa3-Cre; Mcl-1fl/fl mice had significantly reduced IL-13 levels in the peritoneal cavity 3 hours after IL-33 administration when compared with mast cell-containing littermates. In contrast, IL-33-treated eosinophil-deficient \u0394dblGATA mice had similar levels of IL-13 at this time point as wild type controls. These data demonstrate that IL-33 promotes MerTK expression, critical for efferocytosis by macrophages, by a process associated with an early rapid local increase in IL-13 production to which mast cells are a substantial early contributor. These findings contribute to our understanding of clinical situations where elevated soluble IL-33 receptor (sST2) and/or lower mast cell numbers are associated with worse clinical outcome.",

In cerebellar Purkinje cells (PCs), PTEN deficiency leads to hyperactivation of mTORC1, impaired energy homeostasis, and progressive neuronal degeneration. Given that physical exercise is a potent modulator of metabolic signaling, we investigated whether voluntary running could restore metabolic balance and ameliorate cellular and behavioral deficits in a mouse model of PC-specific PTEN deficiency. Using Pten conditional knockout (cKO) mice, we evaluated the effects of voluntary running on motor coordination, metabolic signaling, neuronal morphology and preservation, and social and non-social behaviors. Behavioral analyses revealed that running significantly improved motor performance in Pten cKO mice. At the cellular level, voluntary running increased phosphorylated AMP-activated protein kinase (pAMPK) and restored mitochondrial and lysosomal content in PC dendrites from Pten cKO mice. Unexpectedly, running further enhanced mTORC1 activity in Pten cKO mice, as indicated by increased pS6R immunoreactivity, suggesting a complex interplay between anabolic and catabolic pathways. Behavioral analyses further revealed that voluntary running reduced sex-dependent differences in social and non-social behaviors observed in sedentary Pten cKO mice. Despite persistent dendritic hypertrophy and synaptic VGLUT2 alterations, running reduced PC loss and partially normalized microglial morphology and activation. Together, these findings demonstrate that voluntary running improves metabolic homeostasis and neuronal preservation in Pten cKO mice, even in the presence of sustained mTORC1 activation. Our results highlight the therapeutic potential of physical activity in modulating metabolic pathways and mitigating neurodevelopmental pathology.",

This neoplasm can present with different nonspecific symptoms, including fever, altered mental status, livedoid skin rashes, hepatosplenomegaly, and cytopenias, often complicating its diagnosis. The main categories are classical (formerly designated as Western), hemophagocytic variant (formerly designated as Asian), and primary cutaneous IVLBCL. A distinctly severe manifestation is hemophagocytic lymphohistiocytosis (HLH), a hyperinflammatory syndrome characterized by exaggerated immune activation and macrophage activation manifested by phagocytosis of hematopoietic cells including neutrophils, red blood cells, and platelets. We describe a 72-year-old female who presented with features reminiscent of an autoinflammatory syndrome including fever and hyperferritinemia followed by clinical features concerning for HLH. She developed a reticulated skin rash. Following skin biopsy, a diagnosis was rendered of IVLBCL complicated by HLH.

Yet the impact of maternal stress on offspring susceptibility to stress and its underlying biological mechanisms remain to be elucidated. Here, we established a \"2-hit\" stress model to investigate whether maternal chronic unpredictable stress (E9.5 to E18) increases offspring susceptibility to social isolation during adolescence (P28 to P49). Our study reveals that maternal stress increases susceptibility to adolescent social isolation in male-but not female-offspring, manifested as increased anxiety- and depressive-like behaviors. This vulnerability is mediated by the priming of hippocampal dentate gyrus microglia through the complement C3-C3aR signaling pathway, which promotes the aberrant phagocytosis of excitatory synapses and reduces glutamatergic neuronal activity. Notably, pharmacological blockade of C3aR or chemogenetic activation of glutamatergic neurons in the dentate gyrus during adolescence effectively alleviated stress susceptibility. Therefore, our findings identify a targetable immune-mediated mechanism in the hippocampus that underlies stress vulnerability in offspring exposed to gestational maternal stress, offering new avenues for preventing adolescent-onset mood disorders.",
"42558878": "ID: 42558878\nTitle: Obesity-induced metabolic reprogramming of the tumor immune microenvironment: mechanisms, spatial niches, and immunotherapy response.\nAbstract: Obesity is a major global health challenge and an established risk factor for cancer. Beyond increasing tumor incidence, obesity reshapes the tumor immune microenvironment (TIME) through systemic metabolic reprogramming, adipokine dysregulation, chronic inflammation, and gut microbiota alterations. These systemic changes create spatially organized immunosuppressive metabolic niches, including adipocyte-rich, hypoxic/lactate-enriched, myeloid-dense, and CAF/ECM barrier regions. Such niches restrict effector T-cell and NK-cell function while supporting regulatory T cells, tumor-associated macrophages (TAMs), and myeloid-derived suppressor cells (MDSCs), collectively promoting tumor progression and therapy resistance. Obesity also generates context-dependent effects on immune checkpoint blockade (ICB), a phenomenon known as the \"obesity paradox, \" in which immune suppression coexists with increased checkpoint dependency. Understanding how obesity modulates tumor cell metabolism, immune-cell metabolic fitness, and stromal remodeling is essential for designing effective interventions. Therapeutic strategies combining metabolic modulation, ICB, lifestyle intervention, and microbiota-targeted therapies may convert obesity-driven immune suppression into actionable vulnerabilities. Integrating systemic metabolic indicators, immune-cell signatures, and spatial biomarkers will enable precision stratification of patients and inform combination immunotherapy strategies in obesity-associated cancers.",

Immunological investigations showed no evidence of major humoral, cellular, or phagocytic immune deficiency. To investigate the kinetics of viral shedding and characterize the complete genome of the isolated strain in this case report, longitudinal follow-up stool samples were collected and analyzed using cell culture inoculation, real-time RT-PCRs, and whole-genome sequencing. Virus was detected over a 76 to 126-days observation period. Assuming vaccination occurred in December 2022, the total duration of shedding may have extended up to approximately 138 to 188\u202fdays (4 to 7\u202fmonths) post-vaccination. Despite prolonged replication, the viruses showed limited within-host evolution and retained the major engineered attenuation features of nOPV2, with no evidence of domain V reversion, cre replacement, or recombination, and only limited VP1 divergence which allows its classification as nOPV2 category 8 strains. Our findings underscore the need to further investigate the potential for prolonged excretion and molecular evolution of nOPV2-like strains in immunocompetent individuals.

However, the mechanisms by which circulating factors from HF trigger retinal neuroinflammation remain unclear. HF was induced in adult mice by transverse aortic constriction (TAC). Retinal structure and function were evaluated using optical coherence tomography (OCT) and electroretinography (ERG). Parabiosis and plasma transfer experiments were performed to assess the role of circulating factors. Endothelial senescence, microglial activation, and inflammatory signaling were analyzed using immunofluorescence, qPCR, and molecular assays. The functional relevance of TGF\u03b22 and microglia was tested using anti-TGF\u03b22 antibody administration and microglial depletion with PLX5622 treatment. TAC mice exhibited pronounced retinal thinning, diminished electroretinography (ERG) amplitudes, and reduced vascular density. Exposure of healthy mice to HF plasma reproduced these abnormalities, indicating that circulating mediators drive retinal injuries. TGF\u03b22 levels were markedly elevated in the plasma of both patients with HF and TAC mice. Mechanistically, TGF\u03b22 activated the pSMAD2/EP300 pathway in retinal endothelial cells, promoting H3K9 acetylation, P21 induction, and endothelial cell senescence. Senescent endothelial cells release proinflammatory factors that activate retinal microglia, leading to hypertrophic morphology, enhanced synaptic phagocytosis, and upregulation of cytokines such as IL1\u03b2, TNF\u03b1, and IL6. Neutralization of TGF\u03b22 or microglial depletion markedly reduced inflammation, preserved the retinal architecture, and restored visual function. Elevated TGF\u03b22 levels in heart failure drive retinal endothelial epigenetic senescence, which secondarily activates microglia and induces neuroinflammation. Endothelial-specific disruption of TGF\u03b22 signaling is sufficient to protect the retina independently of primary cardiac recovery. Targeting the TGF\u03b22-endothelial-microglia axis may represent a promising therapeutic strategy for preventing retinal neurovascular degeneration associated with systemic cardiac disease.",

Here, we investigated the neuroimmune effects of polystyrene NPs (100, 200, and 1000nm; 10 and 100\u03bcg/mL) across neuronal (SH-SY5Y, PCNs) and immune cells (THP1, macrophages). Cellular responses were assessed through analyses of cytotoxicity, immunocytochemistry and cytokine profiling. NPs exposure did not induce acute cytotoxicity but promoted persistent intracellular retention accompanied by lysosomal dysfunction, dysregulated autophagic flux, ER stress, and constrained mitochondrial function, thereby inducing a sublethal multi-organelle stress response. Macrophages exhibited greater vulnerability consistent with phagocytic burden, while inflammatory challenge further enhanced NPs uptake, reinforcing intracellular persistence. In contrast, neurons showed limited extracellular cytokine secretion yet accumulated intracellular IL-1\u03b2, suggesting low-grade inflammatory activation. Such responses were recapitulated in PCNs, supporting translational relevance across neuronal models. The cumulative nature of these observations suggests that NPs exposure may give rise to previously unrecognized accumulation-related pathologies, a phenomenon we term \"plasticoma\" as a conceptual framework, to describe the preferential deposition of non-degradable plastic particles within cells, to frame and stimulate future investigations into NP accumulation and pathology. These findings position NPs as potential determinant of neuroimmune dysfunction and highlight the importance of strategies aimed at mitigating their biological accumulation.",

IVW served as the primary estimator, with sensitivity and reverse MR analyses. Two-step MR explored metabolite-mediated pathways. Single-cell RNA-seq from 56 samples across three sources was integrated to resolve HLA-DR+ CD4+ T-cell transcriptional states, evaluate GC genetic-risk enrichment via scDRS, and infer cell-cell communication using CellChat. Twenty-six immunophenotypes showed candidate associations with GC.

A rat model of Pentetrazol (PTZ)-induced EP was constructed to detect the effects of BHB on the symptoms of EP in rats by behavioral assessment, and to detect brain tissue damage by pathological staining. Western blot was conducted to detect microglia polarization markers, neuronal apoptosis, synapse-related proteins, and JAK1/STAT1 pathway-related proteins expression. Pathway specificity was verified using JAK1 overexpression plasmid (OE-JAK1) and STAT1 inhibitor (Fludarabine).\u00a0BHB concentration-dependently increased EP neuron viability and suppressed M1 polarization induced by LPS, and promoted M2 polarization. BHB also enhanced the migration and phagocytosis of microglia, and reduced pro-inflammatory factor release, which in turn attenuated their pro-inflammatory damage to neurons and protected synaptic integrity, and this effect was linked to its suppression of JAK1/STAT1 pathway activation. Additionally, BHB extended seizure latency, decreased seizure duration, and reduced seizure severity in EP rats, and effectively attenuated brain histopathological damage and promoted neuronal regeneration and axonal repair. Furthermore, BHB was also effective in promoting microglia M2 polarization and enhancing their phagocytosis in vivo. Overexpression of JAK1 attenuated the neuroprotective effects of BHB, and Fludarabine attenuated the impacts of overexpression of JAK1.\u00a0By inhibiting the JAK1/STAT1 pathway, BHB promotes microglia M2 polarization and enhances their phagocytosis, attenuates neuroinflammation and neuronal injury, and ultimately exerts anti-EP effects.",

This study evaluated the phytochemical profile and hepatoprotective mechanisms of G. ulmifolia butanol extract (Gul-BuOH) against cadmium-induced liver injury. Gul-BuOH was chemically profiled by UPLC-PDA-ESI-qTOF-MS/MS. Cadmium hepatotoxicity was induced in rats, followed by Gul-BuOH treatment (100 and 200 mg/kg). Liver injury, oxidative stress, inflammation, gene expression (Let-7a, HOTAIR), histopathology, HO-1/Sirt-1 immunoreactivity, and serum metabolomic changes were assessed. Chemical profiling led to the annotation of 42 compounds, including mainly flavonoids and phenolic acids, highlighting the rich phytochemical composition of G. ulmifolia. CdCl2 exposure increased hepatic Cd accumulation and elevated ALT, AST, and ALP, reduced TAC, and increased NO and MDA. Gul-BuOH significantly reduced hepatic Cd levels by 2.6- and 3.2-fold, restored TAC by 38.3% and 83.2%, and decreased NO (56.3% and 63.4%) and MDA (45.4% and 54.6%) at 100 and 200 mg/kg, respectively. Inflammatory markers NF-\u03baB-p and TNF-\u03b1 were markedly suppressed, while miRNA Let-7a was upregulated and lncRNA HOTAIR was downregulated. Histological and immunohistochemical analyses revealed near-complete restoration of hepatic architecture and normalization of HO-1 and Sirt-1 expression at the high dose. Serum metabolomics' OPLS-DA model performance indicators demonstrated strong reliability, with an R2Y (explained variance) of 0.991 and a Q2 (predictive variance) of 0.988). The model identified 36 significantly altered metabolites that were largely normalized by Gul-BuOH, implicating linoleic acid metabolism, amino acid biosynthesis, and ascorbate-related pathways.

"42561511": "ID: 42561511\nTitle: Intrabody B1 targeting TDP-43 modulates neuroinflammatory and metabolic pathways in a preclinical ALS model.\nAbstract: TDP-43 pathology is a hallmark of Amyotrophic Lateral Sclerosis (ALS), yet no therapeutic strategy effectively targets its upstream molecular consequences. Here, we investigated whether the anti-TDP-43 intrabody scFv B1 modulates neuroinflammatory and metabolic pathways in a preclinical ALS model, and whether these effects translate into functional benefit after symptom onset. Using phage display, we previously identified single-chain variable fragments (scFvs) binding TDP-43, including the candidate therapeutic scFv B1. In NSC-34 motor neuron-like cells overexpressing human wildtype TDP-43, B1 reduced NF-\u03baB activation, consistent with disruption of TDP-43-driven inflammatory signaling. For in vivo assessment, B1 was delivered via AAV-CAP.B10 after symptom onset in the hTDP-43(WTxA315T) transgenic mouse model, enabling neuro-specific expression. Two cohorts were analyzed - longitudinal (nine months) and terminal (six months post-treatment) - through behavioral testing, PET imaging, metabolomics, transcriptomics, and plasma biomarker analyses. B1 achieved robust CNS expression and modulated several disease-relevant molecular pathways. RNA-sequencing revealed attenuation of NF-\u03baB-related inflammatory signatures and partial normalization of metabolic and trophic gene expression. Metabolomic profiling identified shifts toward wild-type-like levels in oxidative stress, mitochondrial, and membrane phospholipid metabolites. Despite these molecular effects, symptomatic B1 administration did not improve motor behavior or reduce plasma neurofilament light chain (NfL) concentrations. Notably, plasma TDP-43 levels were stabilized, indicating systemic target engagement. Collectively, scFv B1 modulates upstream pathogenic processes associated with TDP-43 proteinopathy but is insufficient to reverse established neurodegeneration after symptom onset, underscoring the need for earlier and likely combinatorial intervention strategies in ALS.",

We examined PM2.5 components - liver outcomes associations in youth, assessed susceptibility by PNPLA3 genotype (the strongest known MASLD genetic determinant), and evaluated genotype-specific metabolic mediation in two independent cohorts. Baseline data from 113 Los Angeles Latino adolescents with obesity (discovery cohort) were analyzed, including magnetic resonance imaging-measured hepatic fat fraction (HFF), liver stiffness (LS), and serum metabolomics and lipidomics. Visit-year average exposures to 15 PM2.5 components were estimated from residential addresses. Linear regression and g-computation assessed individual component and mixture effects, with PNPLA3 genotype as modifier. Moderated mediation analyses identified metabolic mediators, followed by pathway enrichment and total mediation effect estimation. Findings were replicated in 81 young adults of mixed race/ethnicity and body mass index (replication cohort) using level 1 metabolites confirmed by authentic standards. PM2.5 components and mixture were predominantly positively associated with HFF and LS; simultaneous interquartile range increases in all components were associated with 10.0% higher HFF. Elemental carbon (EC), bromine (Br), copper, potassium, and lead were key contributors. Stronger effects were observed in PNPLA3 GG carriers. GG carriers exhibited more mediating metabolite features (n\u00a0=\u00a0550 vs. 196), with broader pathway enrichment in carbohydrate, lipid, and amino acid metabolism, and signaling/endocrine pathways. Significant total mediation effects were observed exclusively in GG carriers. Replication confirmed GG-specific associations of EC, Br with HFF, and identified increased fatty acid 16:1, and decreased guanidinosuccinate, proline as candidate mediators. PM2.5 components potentially indicative of combustion and traffic sources (i.e. EC, Br) increase MASLD risk in youth via metabolic pathways, with genotype-specific responses likely heightening susceptibility in PNPLA3 GG carriers.",

In this study, we synthesized a library of cholesterol lipids bearing diverse tertiary amine head groups via a straightforward amidation reaction, then co-assembled them with amphiphilic polyethylene glycol-poly (lactic-co-glycolic acid) (PEG-b-PLGA) to formulate hybrid nanomaterials. Notably, the cholesterol derivative A3-Chol-formulated nanomaterials (A3-Chol@NP) polarized macrophages toward the pro-inflammatory M1 phenotype and enhanced phagocytosis of tumor cells. At the mechanistic level, A3-Chol@NP has been observed to preferentially interact with mitochondria in macrophages to produce mitochondrial reactive oxygen species (mtROS). This, in turn, activates ROS-NF-\u03baB-iNOS and ROS-IRF5-IL-23 pathways, which have been identified as key factors in the macrophage polarization to M1-type. In the B16-F10 mouse melanoma model, A3-Chol@NP efficiently suppressed tumor growth via macrophage-mediated immunotherapy and completely blocked tumor progression when combined with anti-PD-L1 antibody.",

However, approximately half of the FTD patients are sporadic without a clear genetic background. To compare characteristics of microglia from different FTD subtypes, we generated induced pluripotent stem cell-derived microglia (iMG) from sporadic and C9-HRE-carrying behavioral variant FTD (bvFTD) patients and healthy controls. C9-HRE iMG displayed C9-HRE-associated RNA foci and dipeptide repeat proteins. All bvFTD iMG had fewer LAMP2-A-positive vesicles compared to control iMG. Additionally, C9-HRE iMG showed significantly increased LC3BII/I conversion after bafilomycin A1 treatment and altered phagocytic activity. The gene expression profile of C9-HRE iMG only modestly differed from the control iMG, but was greatly different from the sporadic bvFTD patient iMG. Our data show alterations in phagocytic and autophagosomal/lysosomal pathways and gene expression profiles between C9-HRE and sporadic bvFTD iMG for the first time.",

Its immunological functions, especially in host defense against bacterial infection, remain unexplored in lower vertebrates. In this study, we identified a GPx-7 homolog from Paralichthys olivaceus (PoGPx-7) and investigated its roles during Vibrio alginolyticus infection. PoGPx-7 possesses a conserved GSH-Px domain and carries positive net charges. PoGPx-7 was constitutively expressed in various tissues, with significant upregulation upon bacterial challenge. Recombinant PoGPx-7 (rPoGPx-7) exhibited GPx activity and bound to V. alginolyticus via interaction with lipopolysaccharide and peptidoglycan. In addition, rPoGPx-7 could directly kill bacteria by disrupting membrane integrity, leading to severe structural damage and content leakage. The bactericidal activity was modulated by protein concentration, pH, temperature, and Zn2+. Furthermore, rPoGPx-7 bound to peripheral blood leukocytes (PBLs), reduced bacterial attachment and LDH release, and protected PBLs from cell death. It also significantly enhanced phagocytosis, respiratory burst, and acid phosphatase activity of PBLs. In vivo administration showed that rPoGPx-7 reduced bacterial loads in the tissues, and improved fish survival, whereas knockdown of PoGPx-7 increased susceptibility to infection. These findings provide the first evidence that teleosts GPx-7 functions as a dual-effector molecule with direct bactericidal activity and immunomodulatory capacity, providing an immunological insight of GPx family members on resistance bacterial infection.",

Its developmental mechanisms remain incompletely elucidated. Altered lipogenesis plays a crucial role in tumor progression. However, the specific mechanisms by which TRIB3 regulates lipid accumulation in esophageal cancer remain unclear. This study aims to investigate how TRIB3-ATF4 interaction influences lipogenic enzyme expression and tumor progression through the ERK1/2 pathway in esophageal cancer. This study employed the esophageal cancer cell lines (TE5 and KYSE150) as a research model. We performed TRIB3 overexpression, knockdown, and ATF4 interaction analyses. These were combined with molecular biology techniques and functional assays (EdU, colony formation, migration, and invasion). Pharmacological inhibitors of ERK and FASN, alongside oleic acid (OA) rescue, validated the signaling and metabolic pathways. TRIB3 regulates fatty acid metabolism. TRIB3 knockdown suppresses fatty acid biosynthesis, cell growth, and migration. Mechanistically, TRIB3 interacts with ATF4 to activate the MEK/ERK pathway. FASN inhibition reverses TRIB3's oncogenic effects. Conversely, OA rescues the tumor-suppressive phenotypes of TRIB3 knockdown. Inhibition of the MEK/ERK pathway attenuates TRIB3-mediated lipid metabolism and progression. This study identifies TRIB3 as a key metabolic regulator in esophageal cancer. It links stress adaptation to lipogenic reprogramming. Targeting this metabolic vulnerability represents a promising therapeutic strategy.",

Shrimp were injected with different PPE dosages including 10 \u03bcg shrimp-1 PPE extract (PPE10), 20 \u03bcg shrimp-1 PPE extract (PPE20), and 40 \u03bcg shrimp-1 PPE extract (PPE40), and immune parameters were assessed, including total haemocyte count (THC), differential haemocyte counts, phenoloxidase (PO) activity, respiratory bursts (RBs) activity, phagocytic activity, clearance efficiency, and lysozyme activity. The results showed that PPE, particularly at the higher dose (PPE40), significantly enhanced THC, hyaline cells, and semigranular cells at later stages post-injection, while granular cells remained unchanged. PPE40 also significantly increased PO activity and RBs, indicating activation of the proPO system and oxidative defense. Additionally, phagocytic activity, clearance efficiency, and lysozyme activity were significantly elevated, demonstrating enhancement of both cellular and humoral immune responses. No significant differences in haemolymph glucose and lactate levels were observed among treatments, indicating that PPE did not induce physiological stress. The enhanced immune responses were further confirmed by a Vibrio alginolyticus challenge test, in which PPE40 exhibited significantly higher survival rates compared to other groups, demonstrating improved disease resistance.",

Here, we investigated the anti-osteoclastogenic activity and molecular mechanism of 2'-O-Galloylhyperin (2'-O-GH), a structurally defined flavonoid derivative. The effects of 2'-O-GH on RANKL-induced osteoclastogenesis were evaluated in bone marrow-derived macrophages and RAW264.7 cells using TRAP staining, qPCR, western blotting, F-actin staining, immunofluorescence, and bone resorption assays. Target identification was performed using a biotinylated 2'-O-GH probe coupled with pull-down and LC-MS/MS analysis, followed by molecular docking and microscale thermophoresis. In vivo efficacy was assessed in an ovariectomy-induced osteoporosis mouse model. 2'-O-GH inhibited RANKL-induced formation of TRAP-positive multinucleated osteoclasts without evident cytotoxicity at effective concentrations. It downregulated osteoclast-related markers, including NFATc1, c-FOS, SRC, ACP5, ATP6V0D2, and CTSK, and impaired F-actin ring formation and bone resorption. Mechanistically, 2'-O-GH restrained RANKL-induced NF-\u03baB p65 nuclear translocation. Chemical proteomics identified MAP3K11/MLK3 as a candidate target, and molecular docking and microscale thermophoresis supported its direct interaction with 2'-O-GH. 2'-O-GH further suppressed RANKL-induced phosphorylation of MLK3 and IKK\u03b1/\u03b2, whereas MLK3 overexpression partially rescued NF-\u03baB activation and osteoclast differentiation. In ovariectomized mice, 2'-O-GH attenuated bone loss without obvious effects on body or uterine weight. These findings identify MLK3 as a pharmacological target of 2'-O-GH and suggest that 2'-O-GH suppresses osteoclastogenesis through the MLK3/IKK/NF-\u03baB axis.",
"42562416": "ID: 42562416\nTitle: Disruption of the CD47-SIRP\u03b1 Axis Causes Profound Reduction of Parasitaemia in Mice Infected With Babesia microti.\nAbstract: Human babesiosis is an emerging disease in North America caused by the red blood cell (RBC)-infecting parasite Babesia microti. Despite a rise in clinical cases in recent years, the pathogenesis and host immune response to B. microti infection remain unclear. CD47 is a 'marker of self' transmembrane glycoprotein expressed on cell membranes that inhibits phagocytosis through interactions with macrophage signal-regulatory protein alpha (SIRP\u03b1). We posit that disruption of CD47-SIRP\u03b1 signalling will induce macrophage uptake of Babesia-infected RBCs and reduce parasitaemia in susceptible hosts. To evaluate this, we compared the in\u00a0vivo clearance of B. microti in CD47 knockout (CD47-/-) mice and wild-type C57BL/6J mice. Our results showed pronounced differences in infection kinetics between the two mouse strains. C57BL/6J mice showed steadily increasing parasitaemia that peaked at an average of 12%, whereas CD47-/- mice exhibited parasitaemia that never exceeded 1.5% throughout infection. Parasitaemia became undetectable by Day 21 in C57BL/6J and by Day 16 in CD47-/- mice, indicating resolution of infection. These results imply that, in the absence of CD47, growth of B. microti is diminished due to more efficient phagocytosis of infected RBCs by macrophages. We propose that CD47-SIRP\u03b1 signalling plays a key role in the innate response to Babesia and suggest CD47 modulation as a new therapeutic target for the treatment of babesiosis.",

Microbial fermentation offers a clean-label strategy to improve flavour while maintaining processing sustainability. In this study, a factorial experimental design was applied to optimise solid-state fermentation of soybeans using two distinct coculture systems: a fungal-fungal system (Neurospora crassa-Rhizopus oryzae), and a fungal-bacterial system (Neurospora crassa-Lactiplantibacillus plantarum). Fermentation temperature (25-30\u00a0\u00b0C), inoculum ratio (1,1,2,1,1,2), and duration (3-5\u00a0days) were evaluated to determine their effects on microbial dynamics, metabolite formation, aroma profiles, and sensory perception. Fermentation significantly reduced beany odorants, with hexanal levels decreasing by up to 95% compared with the uninoculated control. The two coculture systems exhibited distinct flavour regulation pathways. The fungal-bacterial system (N. crassa-L. plantarum) followed a carbohydrate-driven pathway characterised by controlled acidification and selective proteolysis, promoting enrichment of umami-related metabolites, including glutamic acid (up to 1.55\u00a0mg/g), umami-active peptides and nucleotides (guanosine monophosphate and inosine monophosphate), and moderated lactic acid production (<6.5\u00a0g/L). In contrast, the fungal-fungal system (N. crassa-R. oryzae) followed a lipid-driven pathway characterised by enhanced lipolysis and mobilisation of polyunsaturated fatty acids, leading to increased formation of lipid-derived volatiles such as 2,4-decadienal associated with fatty and savoury aromas. These contrasting metabolic pathways were supported by multivariate analysis, confirming distinct taste- and aroma-driven optimisation profiles, demonstrating that flavour development is strongly parameter-dependent. These findings establish a framework for fermentation-enabled flavour engineering in soybean-based alternative proteins.",

However, their ecological functions and underlying mechanisms in high-salt soy sauce fermentation remain largely unexplored. In this study, we investigated phage communities, their potential functions, phage-host interactions, and host defense mechanisms in two different soy sauce fermentation processes (Cantonese-type process, CP; Japanese-type process, JP) using shotgun metagenomics. A total of 823 phage species (viral operational taxonomic units, vOTUs) were identified, with the majority exhibiting a temperate lifestyle (89.19%). The most abundant family was Straboviridae (CP, 9.95%-11.39%; JP, 12.04%-13.73%), followed by Salasmaviridae (CP, 6.92%-7.94%; JP, 5.70%-7.02%). Although the phage composition differed between the two processes, the number of vOTUs was positively correlated with prokaryotic species richness, total acidity, and amino acid nitrogen content, and negatively correlated with pH. A comparative genomic analysis revealed that 91 phages were associated with 26 bacterial genomes (metagenome-assembled genomes, MAGs), with Lactococcus petauri (MAG16) and Halomonas elongata (MAG51) hosting the most phage species. An analysis of host defense mechanisms showed that all 45 bacterial MAGs harbored CRISPR-Cas type I systems, and 95.6% encoded restriction-modification systems. Functional annotation using the KEGG and CAZymes databases indicated that the phages predominantly encoded genes related to cell growth, replication, and metabolism of amino acids, carbohydrates, and nucleotides, with more genes enriched in the JP than in the CP. Additionally, auxiliary metabolic genes (e.g., pfkA, ldh, adhP, ilvE, and arcA) were identified in 29 phages. These genes are potentially involved in metabolic pathways that may be linked to flavor compound production. Together, these findings provide novel insights into the ecological and potential functional roles of phages during soy sauce fermentation.",

Kratom is traditionally consumed in Southeast Asia as a decoction to treat various ailments. In recent years, kratom has gained substantial popularity in Western countries for a range of off-label uses, however, reports of its adverse effects, including fatalities, have raised safety concerns. Because changes in metabolite profiles can indicate alterations in health status, metabolomics provides a valuable tool for assessing the potential benefits and risks of kratom. Although animal studies suggest that kratom influences metabolic pathways and behavior, human data remain limited. Therefore, this study aimed to characterize changes in blood plasma metabolites and associated metabolic pathways in regular kratom users using an NMR-based metabolomics approach. Blood plasma samples were collected from 37 regular kratom users and 12 control subjects (non-users), and analyzed using NMR spectroscopy. Multivariate analysis revealed a clear separation between the two groups, indicating distinct plasma metabolite profiles. A total of 17 metabolites were identified as different between the two groups based on 1H CPMG, JRES and HSQC spectra. Among these, glycine, formate, dimethylamine and N-methyltyramine were significantly increased, whereas pyruvate, \u029f-pyroglutamic acid and citrate were significantly reduced in kratom users compared with non-users. Metabolite enrichment and pathway analyses revealed perturbations in glycine, serine, and threonine metabolism; pyruvate metabolism; glyoxylate and dicarboxylate metabolism; citrate cycle; glycolysis or gluconeogenesis; and glutathione metabolism in kratom users. The biological relevance of these metabolites and pathways is discussed. Overall, these findings provide a better understanding of the metabolic alterations associated with long term kratom consumption in humans.",

This study aimed to investigate the anti-fatigue effects and underlying mechanisms of a novel L-\u03b2-galactoglucan (APG) with two distinct molecular weights in mice under two different swimming load models using multiomics approaches. The results showed that APG could significantly extend exhaustive swimming time, reduce elevated serum lactate and blood urea nitrogen levels, increase muscle glycogen storage, and mitigate swimming-induced skeletal muscle and mitochondrial damage. Compared with its medium-molecular-weight counterpart, high-molecular-weight APG was more effective at improving these indicators. APG optimized the gut microbiota and increased the content of short-chain fatty acids. Specifically, it increased the ratio of Bacteroidetes/Bacillota and promoted the abundance of beneficial bacteria, including Dubosiella, Lachnospiraceae_UCG-006, Parabacteroides, Roseburia, Faecalibaculum and norank_o_Clostridia_vadinBB60_group, while increasing the concentrations of acetic, propanoic, and isobutyric acids. Notably, APG exerted load-specific regulatory effects: In the weight-bearing model, APG modulated mainly purine metabolism, whereas in the non-weight-bearing model, it predominantly regulated tryptophan metabolism. Both pathways converge to synergistically activate AMPK/SIRT1/PGC-1\u03b1 signaling. Molecular docking further verified that APG exhibited strong binding affinity to key targets in these pathways. Collectively, these findings demonstrate that APG exerts anti-fatigue effects in a molecular weight-dependent and load-specific manner via the gut-muscle axis, providing a scientific basis for the development of APG as a targeted anti-fatigue functional ingredient.",

Here, we show that the MYC oncogene and its obligate partner MAX drive a postmitotic hypertranscriptional state in mouse embryonic stem cells. Cell cycle-resolved single-cell RNA-seq in inducible Max -/- cells reveals that early G1 hypertranscription is strongly impaired without MAX. Mechanistically, MAX remains bound to thousands of promoters during mitosis, while MYC is largely excluded. Using high-temporal-resolution profiling, pharmacological inhibition of MYC/MAX, and acute MAX degradation at mitotic exit, we demonstrate that MAX mitotic binding triggers rapid MYC recruitment and transcriptional amplification of TBP-bound promoters by enhancing RNA polymerase II occupancy and efficient initiation and elongation. These findings redefine MYC/MAX as master regulators of gene regulatory inheritance across mitosis.",

We integrated single-cell RNA sequencing, bulk transcriptomics, and senescence-related gene sets to identify key genes. A diagnostic model was constructed using 3 machine-learning algorithms. Mendelian randomization analysis was applied to infer causality. Biliverdin Reductase A (BLVRA)'s role in macrophage senescence was validated through in vitro and in vivo Staphylococcus aureus infection models. Seven diagnostic biomarkers were identified, with a combined model showing high accuracy (area under the curve? > 0.96). Mendelian randomization analysis confirmed a causal effect of BLVRA on OM risk. Single-cell data revealed predominant BLVRA expression in macrophages. Experimental validation showed that Staphylococcus aureus infection upregulates BLVRA and promotes macrophage senescence. BLVRA is a causal mediator of OM linked to macrophage senescence.

Pellagrous CC neurons are morphologically similar to ballooned achromatic neurons in other conditions but the distinct pathomechanisms remain unclear. We performed a clinico-neuropathological analysis of 10 autopsy cases of pellagra encephalopathy. The pellagra encephalopathy cases were immunohistochemically compared with disease controls, including cases of axonal injury and neurodegenerative diseases. Electron microscopic evaluation and immunohistochemical examinations targeting mitochondrial fragmentation were performed for a representative case. Four of 10 pellagra encephalopathy patients exhibited prolonged impairment of consciousness distinguishable from alcohol withdrawal delirium. Pellagrous CC neurons were negative for cytoskeletal markers whereas ballooned achromatic neurons in the disease control cases were positive. Immunohistochemical analysis of mitochondrial markers revealed that CC neurons exhibited more intense immunoreactivity for COX-IV and mitochondrial fissure factor compared to the disease controls. Transmission electron microscopy of these CC neurons revealed a marked increase in the mitochondria with amorphous densities. These findings indicate that the pathomechanism of pellagrous CC is distinct from that of the ballooned achromatic neurons of other etiologies. Mitochondrial alterations in pellagrous CC neurons suggest that neuronal energy deficits resulting from nicotinamide adenine dinucleotide deficiency induce mitochondrial fragmentation.",

Leveraging these properties for biomedical applications demands the ability to measure multiple parameters simultaneously across millions of cells and diverse cell types. However, current technologies are limited by throughput and low dimensionality. Here we introduce spectral biophysical cytometry (SBC), a high-throughput platform that integrates environment-sensitive nanosensors with spectral flow cytometry to resolve multiparametric biophysical properties of immune cells at single-cell resolution. By using fluorescent nanosensors that report membrane order, mitochondrial potential and membrane potential, SBC enables simultaneous quantification of key cellular physical states across diverse immune cell populations. When applied to peripheral blood mononuclear cells, SBC reveals cell-type-specific biophysical heterogeneity and identifies distinct remodelling signatures associated with atherosclerosis. In particular, T-cell subsets exhibit substantial alterations in membrane order and mitochondrial depolarization, reflecting coordinated changes in lipid composition and metabolic pathways. Integration with lipidomics and transcriptomics demonstrates that the nanosensors can detect biophysical shifts that correlate with dysregulated lipid metabolism and mitochondrial function, providing mechanistic insight into immune dysfunction in disease. Importantly, SBC achieves rapid, label-efficient profiling using commercially available instrumentation, enabling scalable biomarker discovery directly from blood samples and establishing a powerful strategy for linking biophysical phenotypes to immune cell function.",

Emerging evidence highlights the intricate interplay between metabolic reprogramming and epigenetic modifications in macrophages, neutrophils, and other innate immune populations within the tumor microenvironment. Tumor-derived metabolites, hypoxia, and nutrient availability dynamically regulate chromatin accessibility, histone modifications, and DNA methylation patterns, thereby driving context-dependent immune phenotypes. Notably, metabolic rewiring can imprint long-lasting epigenetic changes, a phenomenon known as innate immune memory, which alters subsequent immune responses. Here, we discuss how key metabolic pathways, including glycolysis, fatty acid oxidation, and amino acid metabolism, govern innate immune cell fate and function via epigenetic mechanisms. We also highlight recent advances in epigenomic profiling that have unveiled distinct chromatin landscapes associated with innate immune dysfunction across cancer types. Finally, we explore emerging therapeutic strategies that target the metabolic-epigenetic axis to restore innate immune surveillance and enhance immunotherapy efficacy. A deeper understanding of this metabolic-epigenetic crosstalk could reveal novel avenues for modulating innate immunity in cancer therapy.",

Here, we developed a CAR-like signal-switching receptor-macrophage (SR CAR-M) that recognizes IL-10, a major immunosuppressive cytokine enriched in solid tumors, and converts this inhibitory signal into a pro-inflammatory activation through the Toll-like receptor 9 (TLR9) intracellular signaling pathway. SR CAR-Ms effectively blocked IL-10-mediated STAT3 phosphorylation while activating TLR9 downstream signaling, including nuclear translocation of nuclear factor-\u03baB and upregulation of IRF1, thereby adopting an M1-like phenotype with enhanced phagocytic capacity and tumor cytotoxicity. Domain-deletion controls demonstrated that both IL-10 binding and TLR9 signaling are indispensable. In addition, SR CAR-Ms promoted dendritic cell maturation, enhanced T cell proliferation and effector function, and prevented T cell exhaustion. In an orthotopic 4T1 breast cancer model, infused SR CAR-Ms selectively accumulated in tumors, depleted local IL-10 while inducing inflammatory cytokine production, suppressed tumor growth, and prolonged survival without systemic toxicity. The signal-switching mechanism was validated in primary bone marrow-derived macrophages and human monocyte-derived macrophages, supporting the translational applicability. Further enhancement was achieved by engineering dual-function SRP\u03b1 CAR-Ms secreting anti-PD-L1 antibodies, which outperformed either SR CAR-M or anti-PD-L1 monotherapy. The SR CAR-M platform transforms an immunosuppressive cytokine into a location-specific activation trigger, simultaneously depleting the inhibitory signal and remodeling the tumor microenvironment. This signal-switching paradigm offers a versatile approach for treating solid malignancies that are resistant to conventional immunotherapies.",

These pivotal mediators regulate all stages of inflammation, from initiation, progression, and maintenance to resolution and regain of tissue homeostasis. While leukotrienes and prostaglandins, produced from arachidonic acid (AA) by the 5-lipoxygenase (LOX) and cyclooxygenase (COX) pathways, respectively, mediate/promote inflammatory reactions and related symptoms, the specialized pro-resolving mediators (SPMs) terminate and resolve inflammation. SPMs encompass mainly the omega-3-PUFA-derived resolvins, protectins, and maresins, which are synthesized by sequential PUFA oxygenation steps, involving primarily 15-LOX-1/2 isoforms, but for some specific SPMs, also the 5-LOX, 12-LOX, COX-2, and cytochrome P450 enzymes mediate one of these oxygenations. Due to their valuable inflammation-resolving features, different strategies have been developed in order to exploit the beneficial functions of SPMs for the intervention with chronic inflammatory diseases. Here, we review the promising strategy of promoting endogenous SPM formation by applying exogenous agents that activate SPM-biosynthetic enzymes, also in combination with omega-3-PUFA supplementation, for resolution pharmacology. Results from pilot clinical trials that confirm the applicability and efficacy of such agents and their combinations in patients suffering from chronic inflammatory disorders are briefly discussed.",

Mechanistic exploration indicated that BSP suppresses osteoclastogenesis primarily by targeting matrix metalloproteinase-9 (MMP9), thereby inhibiting proteolytic activity and cytoskeletal remodeling. Preliminary rescue experiments supported this notion, showing that while BSP effectively downregulated LPS-induced MMP9 upregulation and suppressed macrophage glycolytic metabolism, forced overexpression of MMP9 partially restored MMP9 levels and reversed the inhibitory effect of BSP on osteoclast formation. These findings suggest a potential \"metabolism-protease\" interplay, where BSP concurrently modulates immune metabolism and protease activity to alleviate inflammatory bone loss, providing a foundational basis for developing plant-derived polysaccharide therapeutics.",

Radical alterations in axonal and dendritic microtubules characterize both the acute injury phase and the protracted recovery period. For decades, researchers have sought to correct these microtubule defects as a therapeutic strategy to encourage axonal regeneration, collateral sprouting, and the functional rewiring of neuronal circuits. Recent studies have demonstrated that taxol and related microtubule-active drugs improve outcomes in rodent models. These benefits are achieved by preventing microtubule depolymerization, stabilizing existing polymers, and promoting new assembly within both afflicted neurons and the glial cells essential for repair. While these findings highlight the therapeutic potential of microtubule-based interventions, we posit that successful clinical translation necessitates a more sophisticated approach rooted in the growing knowledge of microtubule-related proteins and their intricate regulatory mechanisms. This review evaluates progress in this arena, specifically examining the microtubule interactome network that includes structural microtubule-associated proteins (MAPs) such as Tau, MAP1A, MAP1B, MAP2, and MAP6, as well as the stathmin family, plus-end tracking proteins, and microtubule-severing proteins such as fidgetin and spastin. In addition, we analyze the contribution of molecular motor proteins and regulatory MAPs, including CRMP2 and CRMP4, as well as upstream transcription factors governing their expression. Finally, we address convergent regulation through kinases such as GSK3\u03b2 and CDK5, which represent a central mechanistic axis linking injury signaling to cytoskeletal failure. By integrating data from studies on development and regeneration into a unified mechanistic model, we provide a framework for microtubule-based therapeutics for SCI.",

However, long-term outcomes and potential challenges following such combination therapies remain poorly documented. A 40-year-old woman with generalized stage III grade C periodontitis underwent periodontal regenerative therapy using rhFGF-2 combined with DBBM for a one-wall defect at the mandibular left first molar (#19). Favorable periodontal healing was maintained for approximately 4 years. However, for tooth #19, the probing depth gradually increased at 5 years 2 months post-surgery, and the patient developed discomfort and pulpal symptoms by 6 years 2 months. Clinical examination revealed an agglomerate of DBBM particles and a palpable external root resorption lesion. The tooth was extracted due to irreversible pulpal involvement. This case illustrates that despite favorable early healing, periodontal regenerative therapy may lead to rare late-onset complications such as external root resorption. Long-term follow-up and careful consideration of biomaterial interactions are essential when employing combination regenerative approaches. Periodontal regenerative therapy using rhFGF-2 and DBBM achieved favorable clinical outcomes for 4 years before unexpected late-onset external root resorption developed. Long-term persistence and partial separation of DBBM particles, along with the response of macrophage- or osteoclast-lineage cells, are associated with a potential for delayed resorptive pathology on adjacent root surfaces. Clinicians should recognize the possibility of late complications and carefully consider biomaterial interactions when selecting regenerative strategies and informing patients. This case report describes a rare situation in which a molar initially healed well after periodontal regenerative therapy using rhFGF\u20102 and a bone substitute (DBBM), but developed external root resorption more than five years later. Although the treatment first reduced inflammation and improved tissue support, the long\u2010term presence of graft particles, together with complex cellular responses, may be linked to delayed changes on the root surface. This case highlights that even when early healing is successful, long\u2010term monitoring is essential, and clinicians should carefully consider how different regenerative materials may interact over time.",

The lung is an attractive site for local intervention because it is directly accessible and immunologically specialized. However, effective pulmonary delivery is constrained by mucociliary clearance, airway mucus, alveolar macrophage uptake, and epithelial barriers. Nanomaterials can be rationally engineered to address these constraints, increasing pulmonary retention and concentrating immunotherapeutics within the lung tumor microenvironment while reducing systemic burden. This Review summarized the key physiological barriers for pulmonary immunotherapeutic delivery and discusses how nanomaterial properties shape deposition, retention, cellular partitioning, and downstream immune activation. We critically evaluate representative inhalable platforms across major immunotherapeutic modalities, including vaccines, immune checkpoint blockade, innate immune agonists (e.g., STING agonists), cytokine regulation, and emerging in situ immune-cell engineering strategies. We also highlight translational considerations. Together, these advances support inhalable immunotherapeutic nanomedicines as a complementary approach to current lung cancer treatment and a broader framework for pulmonary immune modulation.",
"42563401": "ID: 42563401\nTitle: A multi-stage deep learning framework for half-detector truncation and metal artifact reduction in CBCT.\nAbstract: Cone-beam computed tomography (CBCT) is widely utilized for its high spatial resolution and compact design. However, image quality is often compromised in the half-detector (HD) geometry, where data truncation arising from the offset detector configuration coexists with metal artifacts caused by metallic implants. These artifacts interact synergistically, leading to severe image degradation that conventional correction methods fail to\u00a0address. We propose a multi-stage deep learning framework, HD-TMAR, to systematically decompose and correct combined truncation and metal artifacts in HD CBCT. The proposed framework adopts a multi-stage restoration strategy comprising three stages: (1) Sinogram Correction, which explicitly isolates the artifact residuals from the projection data and synergizes them with structural prior-normalized features to systematically suppress global truncation biases and metal artifacts; (2) Merging and Reconstruction, which employs a specialized overlapping patching and selective replacement strategy to accurately reconstruct the truncated regions and metal traces; and (3) Image Refinement, where ImgNet further enhances the reconstructed image to restore fine anatomical\u00a0textures. Experiments using realistic simulation datasets demonstrated that the proposed method achieved the highest qualitative fidelity and quantitative metrics compared to previous deep learning MAR methods. The framework effectively suppressed severe artifacts while preserving dental morphology, whereas comparative methods suffered from secondary artifacts or\u00a0blurring. HD-TMAR successfully disentangles complex artifact interactions. By synergizing sinogram-domain correction with image-domain refinement, the framework demonstrates promising potential for clinical application in enhancing the diagnostic performance of HD CBCT systems in the presence of metallic\u00a0implants.",

We present a DiceCT-based digital atlas of a human hand from a consented female donor through the University of Missouri Gift of Body program, scanned at 48.8\u2009\u03bcm resolution following Lugol's iodine staining. Bones, tendons, intrinsic muscles, neurovascular structures, the flexor retinaculum and carpal tunnel, and dorsal digital expansions were manually segmented to generate labeled multiplanar sections and three-dimensional reconstructions. The dataset resolves epidermal ridge detail on the palmar surface while capturing structures, including the carpal tunnel contents, extensor mechanism, neurovasculature, palmar fat pads, and metacarpophalangeal sesamoids. Reconstructions demonstrate relevant relationships among the median nerve, flexor tendons, and flexor retinaculum, the ulnar nerve within Guyon's canal and the radial artery within the anatomical snuffbox. Distal digital arterial anastomoses are visible near the terminal tufts, and radial artery branches supplying the dorsal and distal scaphoid poles provide context for scaphoid vascular vulnerability. Muscle volumes and physiological cross-sectional areas were calculated using all fascicles within each intrinsic muscle. Flexor pollicis brevis and adductor pollicis exhibited comparatively large relative physiological cross-sectional areas, whereas the lumbricals had the smallest values, consistent with previous architectural estimates. By documenting whole-hand anatomy and within-individual muscle architecture non-destructively, this atlas provides a high-fidelity resource for anatomical education, documentation of anatomical variation, clinical interpretation, and generation of anatomically consistent biomechanical models. These results support DiceCT as a platform bridging anatomical research, clinical translation, and pedagogical access to donor-specific human anatomy.",

Despite its prevalence, there are currently no effective pharmacological therapies targeting MetS, highlighting the need to identify novel etiological mechanisms, particularly within the gastrointestinal (GI) tract. Using a mouse model of MetS and healthy lean controls, we assessed the colonic microenvironment through metabolomic, transcriptomic, and microbiome analyses. Colonic organoids were cultured to further explore epithelial alterations. Additionally, human MetS fecal metabolomics data were cross-compared with the mouse model to validate translational relevance. MetS mice exhibited upregulation of colonic anabolic pathways, including glycolysis, the pentose phosphate pathway, and the tryptophan/kynurenine pathway, without evidence of intestinal inflammation. Microbiome analysis revealed an increased abundance of the genus Lactobacillus in MS NASH mice. Colonic organoids from MetS mice showed altered goblet cell differentiation. Comparative analysis with human MetS fecal metabolomics demonstrated similar dysregulated pathways, underscoring the translational relevance of these findings. Our study reveals significant metabolic and microbial alterations in the colon of MS NASH mice, implicating a dysfunctional GI tract as a potential etiological factor in MetS. These findings highlight specific metabolic pathways and microbial signatures that could serve as future therapeutic targets for MetS.",

Lentils are abundant in these compounds, yet comparative studies across varieties and intestinal cells effects remain limited. This study evaluated the nutritional composition, phenolic profile, antioxidant activity, and \u03b1-glucosidase inhibition of four lentil types in raw and cooked forms. L01 had the highest bioactive potential and was the only one selected for further evaluation in Caco-2 cells under basal and IL-1\u03b2-stimulated conditions. Cooking altered composition, leading to higher protein, fiber, and carbohydrates, reducing tannins, and maintaining high phytic acid in some varieties. L01 consistently showed the highest phenolic content, antioxidant activity, and enzyme inhibition. Its phenolic profile was dominated by kaempferol derivatives, (epi)catechin, and procyanidins, with cooking increasing monomeric catechins but reducing procyanidin oligomers. At noncytotoxic levels, L01 extracts reduced IL-6/8 secretion in stimulated cells, with stronger effects from raw extracts. Additionally, they decreased expression of inflammatory markers (IL-6/8/1\u03b2) while increasing expression of metabolic regulation- and barrier-related genes (Peroxisome proliferator-activated receptor-\u03b3, Sirtuin 1, Occludin, and Cadherin-1). Only raw extracts significantly enhanced Heme oxygenase-1 expression under stimulation. These findings highlight compositional differences beyond tegument color and support further investigation of phenolic-rich lentils as potential functional food ingredients targeting gut and metabolic health.",

These self-assembling, two-dimensional arrays represent a major evolutionary investment, often accounting for up to 10% of total cellular protein synthesis. Despite enormous sequence diversity and adaptation to widely different ecological niches, S-layers persist across phylogeny, suggesting a fundamental selective advantage. In this review, we synthesize historical ultrastructural observations with modern atomic-resolution structural data and biophysical principles to demonstrate that antifouling is a general and fundamental function of all bacterial and archaeal S-layers. We argue that antifouling arises from a sophisticated synergy of lattice dynamics, crystalline nanotopography, electrostatic mosaicity, fragmented hydrophobicity, structured hydration shells and frequently glycan-mediated steric repulsion. We specifically place S-layer antifouling into the physical framework of life at low Reynolds numbers, where even minimal surface fouling imposes severe energetic penalties on nutrient acquisition and motility. We also highlight the S-layer as a tunable interface that suppresses non-specific fouling while precisely gating specific molecular interactions and community formation. Finally, we discuss how this universal biophysical strategy provides a powerful blueprint for biomimetic surface engineering in (nano)biotechnology, synthetic biology, and materials science.",

A retrospective analysis was performed on patients with acute TBIMH without ulcer-like lesions who received medical management. Patients were categorized into progression and nonprogression groups based on 1-year follow-up computed tomography angiography (CTA). Disease progression was defined as aortic rupture, aortic dissection, aortic enlargement (\u22655\u00a0mm), or hematoma thickening (\u22653\u00a0mm), while nonprogression was defined as complete/partial resolution or retention of the hematoma. A multivariate analysis identified the predictors of disease progression, and Kaplan-Meier curves were used to compare survival outcomes. A total of 110 patients (mean age 55.9\u00b110.5\u00a0y, 25 females) were included, with 21 patients (19.1%) showing disease progression. Multivariate analysis revealed that the maximum aortic diameter (MAD) (OR=7.6, P=0.003) and maximum CT value of the hematoma (CTmax) (OR=1.04, P=0.025) were independently associated with disease progression. The optimal cutoff values for MAD and CTmax were 40.0\u00a0mm (AUC: 0.69, sensitivity: 38.1%, specificity: 92.1%) and 71.9 HU (AUC: 0.68, sensitivity: 76.2%, specificity: 66.3%), respectively. When MAD and CTmax were combined, the AUC increased to 0.75 (sensitivity: 81.0%, specificity: 66.3%). A model based on MAD and CTmax effectively stratifies progression risk in TBIMH without ulcer-like lesions, facilitating early intervention in high-risk patients.",

Solute carrier family 7 member 5 (SLC7A5), a core transporter that facilitates the transmembrane movement of tryptophan, plays a role in various cancers. However, whether and how SLC7A5 promotes colorectal liver metastasis (CRLM) through tryptophan metabolism reprogramming and immune remodelling remain unexplored. We integrated public datasets and clinical specimens to analyse SLC7A5 expression and prognosis, and validated its role in proliferation and metastasis using in vitro assays and in vivo models. Targeted metabolomics and isotope tracing identified kynurenine (Kyn) and xanthurenic acid (XANA) as downstream metabolites of SLC7A5. Single-cell RNA sequencing (scRNA-seq) and conditioned medium experiments were used to assess the impact of SLC7A5 on the tumour immune microenvironment (TIME). SLC7A5 expression increases sequentially in normal tissue, primary tumours and liver metastases, and higher SLC7A5 levels are associated with worse prognosis. SLC7A5 facilitates CRC cell growth, metastasis and epithelial\u2012mesenchymal transition (EMT) by promoting the production of Kyn and XANA and subsequent activation of the aryl hydrocarbon receptor (AhR). scRNA-seq analysis and conditioned medium experiments demonstrated that SLC7A5 knockdown reprograms the TIME by driving macrophages towards an antigen-presenting phenotype, alleviating CD8+ T-cell exhaustion, polarising CD4+ T cells towards Th1/Th17 subsets and triggering antigen-driven immunoglobulin G (IgG)-secreting B-cell clonal expansion, effects that were reversed by exogenous Kyn/XANA supplementation. Moreover, combination therapy with the SLC7A5 inhibitor JPH203 and anti-programmed cell death protein 1 (PD-1) antibody produced synergistic tumour growth inhibition and heightened antitumour immune responses. Collectively, our findings reveal that SLC7A5 drives CRLM through tryptophan/Kyn/XANA-AhR signalling and concomitant remodelling of the TIME, positioning SLC7A5 as a promising target for combination therapy with anti-PD-1 in CRLM.",
"42563507": "ID: 42563507\nTitle: Single-Nucleus Transcriptome Analysis Provides New Insights Into B Chromosome Elimination in Sorghum.\nAbstract: B chromosomes are supernumerary entities found in many plant species, with some exhibiting tissue-specific elimination. In Sorghum purpureosericeum, extensive B chromosome elimination occurs during embryogenesis affecting most of the embryonic organs, leaving the B chromosome maintained mainly in limited regions of meristems. The dynamics of the process and rarity of the transcripts associated with elimination make capturing it challenging. To address this, we performed single-nucleus RNA sequencing (snRNA-seq) on embryos undergoing B chromosome elimination. This approach enabled detection of more B-linked transcripts compared to previous methods. Notably, we identified nuclei with B-specific transcripts, which predominantly clustered in a single cluster in both replicates of B-positive embryos. Further analysis of these clusters revealed three subpopulations with divergent transcriptional profiles. One subpopulation showed gene expression patterns suggesting active elimination of the B chromosome, while the other subpopulations are expected to exhibit regular segregation of the B chromosome and/or preparation for the elimination process. Our analysis provides resolution so far missing in current studies and highlights a clear benefit of the single-cell approaches for studying specific behaviour of the B chromosomes.",

Although sarcomere mutations such as cardiac actin ACTC1 p.T126I contribute to familial DCM, the in vivo effects and sex-specific consequences remain unclear. We generated a zebrafish model carrying the orthologous Acta1b p.T126I mutation and conducted longitudinal, sex-stratified analyses of cardiac function, morphology and gene expression. Mutants showed variable onset of cardiac dysfunction, with progressive DCM, pericardial effusion, ventricular dilation, and reduced survival in adults. Female mutants exhibited earlier and sustained diastolic dysfunction, greater cardiac remodeling and significantly lower survival compared to males, revealing pronounced sexual dimorphism. Molecular profiling at a pre-symptomatic stage identified upregulation of nppb, downregulation of hypertrophic transcription factors (gata4, mef2ca), and sex-specific alterations in calcium handling genes (serca2, pln1, slc8a1a) and proteostasis regulators (hsf1, bag3). Older stages demonstrated a variable shift of individuals' gene expression to cardiac remodeling and decompensation. These findings demonstrate that the Acta1b p.T126I mutation drives progressive, sex-specific DCM in zebrafish, highlighting biological sex as a critical modifier of sarcomeric cardiomyopathy progression and targeted therapy development.",

To characterize this lesion, 515 sebaceous neoplasms diagnosed in dogs of different breeds between 2017 and 2025 were retrospectively reviewed. Among these, 2 of 255 epitheliomas (0.7%) and 22 of 41 adenocarcinomas (54%) arising in the lips exhibited a distinctive peripheral basaloid epithelial proliferation. The lesion was observed only in the lower lip of Labrador retrievers, occurring in association with either solitary or multifocal neoplastic nodules. No similar proliferations were identified after examining 103 labial lesions of other histotypes diagnosed in the same timeframe. Histologically, the proliferations consisted of 1- to 2-cell-thick epithelial cords surrounding pre-existing adnexal units. The cells showed minimal atypia and low mitotic activity. Immunohistochemically, they exhibited a cytokeratin (CK)5+/p63+/alpha-smooth muscle actin-/CK7- phenotype, supporting derivation from basal reserve cells of cutaneous glands and excluding differentiation toward mature apocrine epithelial or myoepithelial cells. The exclusive occurrence in Labrador retrievers suggests a possible breed-related predisposition. Although the biological behavior of this novel lesion is unknown, its recognition may be important in diagnostic pathology to avoid misinterpretation with an invasive adenocarcinoma.",

This study explores the potential of Se in alleviating Mn-induced stress in Malus domestica Borkh. cv. Red Fuji, a cultivar known for its sensitivity to Mn. Through a combination of physiological analysis and transcriptomic profiling, we provide comprehensive insights into the mechanisms by which Se enhances Mn tolerance. The results demonstrated that selenite application balanced nutrient elements, stabilized the photosynthetic system, and reduced oxidative stress. Additionally, selenite promoted cell wall remodeling and modulated hormone levels. Transcriptome analysis further revealed that selenite regulated genes associated with polyunsaturated fatty acid hydrolase, sucrose hydrolase, and photosynthesis, indicating its role in alleviating Mn stress. GO and KEGG enrichment analyses highlighted that differentially expressed genes were enriched in pathways related to phenylpropanoid biosynthesis, alpha-linolenic acid metabolism, and galactose metabolism, suggesting key metabolic pathways involved in Mn stress responses. Weighted gene co-expression network analysis (WGCNA) identified core module genes strongly correlated with antioxidant enzymes and substances, chlorophyll content, and mineral element concentrations. In conclusion, Se effectively mitigates Mn stress in 'Fuji' apples through multi-level regulatory mechanisms, providing a theoretical foundation for the application of Se-enriched agriculture in apple cultivation.",

Although the sodium-glucose co-transporter 2 (SGLT2) inhibitors have proven reno-protective properties extending beyond that explained by glucose lowering alone, unique glucose-independent molecular mechanisms are still incompletely defined. Unveiling these non-glycemic metabolic pathways is of paramount importance for new therapeutic targets and optimized clinical management. A systematic multi-omics triangulation framework integrating Mendelian randomization (MR) with tissue-specific transcriptomics was conducted. Two-sample MR and multivariable Mendelian randomization (MVMR) adjusted for fasting blood glucose were leveraged as a screening tool to detect glucose-independent serum metabolites in humans using large-scale genome-wide association study data. These findings were validated with transcriptomic signatures from both diabetic and non-diabetic mouse kidney models to identify conserved core genes and convergent metabolic pathways. Genetically proxied SGLT2 inhibition associated with a reduced risk of DKD, with an odds ratio of 0.58, and improved renal function markers. MVMR highlighted 259 glucose-independent metabolites, covering systemic alterations in lipid and amino acid metabolism. A cross-model transcriptomic comparison revealed seven key genes functionally enriched in fatty acid oxidation and ketone body utilization. This convergence supports the concept of a fasting-like metabolic switch and coordinated downregulation of fibrosis-related extracellular matrix pathways irrespective of diabetic status. This study delineates a systemic-renal metabolic axis whereby SGLT2 inhibition drives renoprotection via metabolic reprogramming and anti-fibrotic mechanisms distinct from blood glucose lowering. These findings provide genetic evidence for specific non-glycemic targets and represent a novel mechanistic insight for precision therapeutic intervention in kidney disease.",

Waist-to-BMI ratio (WBR) may better reflect adverse body composition. We examined cross-sectional and longitudinal associations between WBR and musculoskeletal disorders in T2DM. This two-phase study was conducted within an ongoing hospital-based cohort at the First Affiliated Hospital of Fujian Medical University (Fuzhou, China). The cross-sectional analysis included 4157 adults with T2DM recruited between March 2012 and August 2023 (54.3% men; mean age 59.4\u2009\u00b1\u200910.3\u2009years), using data from their first assessment. Associations of waist circumference (WC), waist-to-height ratio (WHtR), waist-to-hip ratio (WHR), BMI and WBR with osteopenia, sarcopenia, sarcopenic osteopenia (SOs), sarcopenic obesity (SOb) and fractures were evaluated. The prospective cohort comprised a longitudinal subset enrolled between March 2012 and June 2022, ensuring at least 1\u2009year of follow-up prior to administrative censoring in August 2023. A total of 440 individuals (57.0% men; mean age 59.7\u2009\u00b1\u20099.7\u2009years) were followed for a median of 34.0\u2009months (20.0-57.0). Associations between time-dependent WBR and incident outcomes were assessed using Cox models. A nested exploratory analysis was conducted within the cohort. Thirty participants with extreme annualised WBR change (\u0394WBR/yr) were selected. Baseline serum samples collected at enrolment, prior to outcome occurrence, were analysed using phage immunoprecipitation sequencing (PhIP-Seq). Cross-sectionally, WBR was negatively correlated with bone mineral density and appendicular skeletal muscle mass index and positively correlated with osteopenia, sarcopenia, SOs, SOb and fractures (all p\u2009<\u20090.01), whereas BMI, WC, WHtR and WHR showed weaker associations. After adjustment, higher WBR was independently associated with osteopenia (men: OR 1.723, 95% CI 1.614-1.840; women: OR 1.420, 1.348-1.495), sarcopenia (men: OR 4.779, 4.165-5.484; women: OR 2.991, 2.683-3.334), SOs (men: OR 6.261, 5.314-7.377; women: OR 4.336, 3.753-5.010), SOb (men: OR 4.737, 3.975-5.646; women: OR 4.652, 3.715-5.825) and fractures (men: OR 1.236, 1.093-1.397; women: OR 1.103, 1.003-1.213; all p\u2009<\u20090.05). Prospectively, higher time-dependent WBR predicted incident osteopenia (HR 1.365, 95% CI 1.024-1.820), sarcopenia (HR 1.282, 1.086-1.512), SOs (HR 1.408, 1.176-1.686), SOb (HR 1.634, 1.262-2.116) and fractures (HR 1.369, 1.029-1.821). PhIP-Seq analysis identified differential autoantibody reactivity related to muscle structural organisation and cytoskeletal regulation, while bone-related differences were enriched in Wnt signalling and hormone-related pathways. Higher WBR and longitudinal increases were independently associated with osteopenia, sarcopenia, sarcopenic phenotypes and fractures in individuals with T2DM.",

Research output increased steadily from 2015 and peaked in 2023, reflecting growing global interest. The United States and China were the most productive countries, with strong collaborative ties observed among institutions in North America, Europe, and East Asia. University College Cork, University of California System, and Harvard University were the leading institutions, while J. F. Cryan, T. G. Dinan, and G. Clarke were the most influential authors.

We hypothesized that chitosan film-based three-dimensional (3D) culture rejuvenates BMSC potency, synergistically promoting angiogenesis and immunomodulation for vascularized bone regeneration. Mouse BMSCs were cultured into spheroids on chitosan films. Their stemness, proliferation, migration, senescence, osteogenic, and proangiogenic potential were compared with 2D cultures. Paracrine effects were evaluated by treating human umbilical vein endothelial cells (HUVECs) and RAW264.7 macrophages with BMSC-conditioned medium (CM). In vivo, gelatin methacryloyl (GelMA) hydrogel-encapsulated 3D-BMSC spheroids were implanted into mouse critical-size cranial defects. Compared to 2D counterparts, 3D-BMSCs exhibited increased stemness, proliferation, migration, delayed senescence, osteogenic differentiation, and enhanced proangiogenic potential. We observed that conditioned medium from 3D-BMSCs (3D-CM) was associated with in vitro angiogenesis and orchestrated a proreparative microenvironment by promoting M2 macrophage polarization and suppressing M1 inflammation. In vivo, GelMA + 3D-BMSC spheroids achieved greater bone regeneration, which was accompanied by a proreparative immune microenvironment and enhanced CD31/EMCN-positive H-type-like vessel formation. This chitosan film-based 3D culture system effectively augments BMSC therapeutic potency, simultaneously enhancing intrinsic cell properties and orchestrating a proregenerative microenvironment, thereby offering a promising experimental platform for critical-sized bone defect repair.",
"42563678": "ID: 42563678\nTitle: [Study on cellular repressor of E1A-stimulated genes regulating autophagy and polarization of alveolar macrophages in sepsis-induced acute respiratory distress syndrome and its clinical value].\nAbstract: To investigate the regulatory effects of cellular repressor of E1A-stimulated gene (CREG) on autophagy and polarization of alveolar macrophages in sepsis-induced acute respiratory distress syndrome (ARDS) and its clinical value. 1) Cell experiment: Mouse monocyte/macrophage cell line RAW264.7 was cultured in vitro. Cells in logarithmic growth phase were induced to differentiate into alveolar macrophages. The alveolar macrophages were divided into four groups: the blank control group was cultured with complete medium only; the lipopolysaccharide (LPS) group was stimulated with 5 mg/L LPS for 24 hours to establish the sepsis-induced ARDS model; the CREG overexpression group was transfected with 2 mg CREG overexpression plasmid pLNCX2-CREG for 6 hours, followed by 5 mg/L LPS stimulation for 24 hours; the CREG interference group was transfected with 2 \u03bcg CREG interference plasmid pSM2-siCREG for 6 hours, followed by 5 mg/L LPS stimulation for 24 hours. Western blotting was used to detect the expression of autophagy markers [autophagy initiation key protein Beclin1, microtubule-associated protein 1 light chain 3 (LC3), and autophagic substrate protein p62]. Flow cytometry was used to detect the expression of macrophage polarization markers [M1-type characteristic marker cluster of differentiation 86 (CD86) and M2-type characteristic marker CD206]. 2) Clinical trial: A prospective case-control study was conducted in patients with sepsis admitted to the respiratory intensive care unit of The First Affiliated Hospital of Hebei North University from January to December 2024. Patients were divided into sepsis with ARDS group and sepsis without ARDS group based on whether they developed ARDS within 72 hours after enrollment. In addition, healthy volunteers who underwent health check-ups at the hospital during the same period were selected as the controls. Demographic data including gender, age, Acute Physiology And Chronic Health Evaluation II (APACHE II) score, oxygenation index (PaO2/FiO2), and laboratory parameters were collected for each group, as well as the sites of infection for the septic patients. Serum levels of CREG and inflammatory markers [interleukin-6 (IL-6), tumor necrosis factor-\u03b1 (TNF-\u03b1), procalcitonin (PCT), and C-reactive protein (CRP)] were measured using enzyme-linked immunosorbent assay (ELISA). The differences in the above indicators were compared among groups. Multivariate Logistic regression analysis was used to identify independent influencing factors for sepsis complicated with ARDS. Receiver operator characteristic curve (ROC curve) was plotted to evaluate the predictive value of CREG for sepsis complicated with ARDS. 1) Cell experiment results: Compared with the blank control group, the expressions of Beclin1, LC3-II/LC3-I ratio, and CD206 were decreased in each LPS group [Beclin1 protein (Beclin1/\u03b2-actin): 0.32\u00b10.05 vs. 0.87\u00b10.09, LC3-II/LC3-I ratio: 0.41\u00b10.06 vs. 1.24\u00b10.11, CD206: (27.14\u00b13.52)% vs. (51.78\u00b15.91)%, all P<0.05], while p62 and CD86 expressions were increased [p62 protein (p62/\u03b2-actin): 1.58\u00b10.13 vs. 0.53\u00b10.07, CD86: (38.35\u00b14.67)% vs. (18.26\u00b13.24)%, both P<0.05]. CREG overexpression significantly improved the above autophagy and polarization indicators, whereas CREG interference further exacerbated these indicators (all P<0.05). 2) Clinical trial results: Ultimately, 40 patients were included in the sepsis with ARDS group, 60 in the sepsis without ARDS group, and 20 in the healthy control group. There were no statistically significant differences in gender, age among the three groups, nor in the distribution of infection sites between the sepsis with ARDS and sepsis without ARDS groups (all P>0.05). Compared with the healthy control group, the patients with sepsis showed aggravated systemic inflammatory burden. Compared with the sepsis without ARDS group, the sepsis with ARDS group exhibited more severe disease, with lower PaO2/FiO2 and CREG levels, and higher levels of inflammatory markers (all P<0.05). As APACHE II score increased, serum CREG levels decreased progressively while inflammatory marker levels increased progressively. Multivariate Logistic regression analysis showed that elevated APACHE II score and inflammatory markers were independent risk factors for sepsis complicated with ARDS [all odds ratio (OR) >1, all P<0.05], while elevated CREG was a protective factor [OR=0.385, 95% confidence interval (95%CI) was 0.344-0.432, P=0.015]. ROC curve analysis showed that the area under the ROC curve (AUC) of CREG for predicting sepsis complicated with ARDS was 0.806 (95%CI was 0.713-0.899); at the optimal cut-off value of 7.85 \u03bcg/L, the sensitivity was 71.43% and the specificity was 78.57%. CREG exerts a protective role in sepsis-induced ARDS by positively regulating alveolar macrophage autophagy activity and correcting M1/M2 polarization imbalance. Elevated serum CREG is a protective factor for sepsis complicated with ARDS and has early predictive value for sepsis-induced ARDS.",

A prospective observational study was conducted. Sixty-three adult patients with confirmed sepsis admitted to the department of critical care medicine of The First Affiliated Hospital of Xinjiang Medical University from July 2024 to June 2025 were consecutively enrolled. According to the cardiac troponin I (cTnI) level on the first day of admission, the patients were divided into SIMI group (cTnI\u22650.04 \u03bcg/L) and sepsis without myocardial injury group (cTnI<0.04 \u03bcg/L). The demographic data, admission-related scores, and laboratory indicators of septic patients, measured indicators such as MIF and interleukin-18 (IL-18) within 24 hours of patients' admission to the intensive care unit (ICU) were collected, and the indicators such as Acute Physiology And Chronic Health Evaluation II (APACHE II) score, Sequential Organ Failure Assessment (SOFA) score, oxygenation index, and echocardiographic indicators within 24 hours of patients' admission to the ICU were recorded. The clinical data of the two groups of patients were compared. The correlation between indicators was analyzed by using Pearson or Spearman rank correlation method. A receiver operator characteristic curve (ROC curve) was drawn to evaluate the predictive performance of MIF, IL-18, and their combination for 28-day death in septic patients. Multivariate Logistic regression analysis was used to screen independent risk factors for 28-day death in septic patients, and a nomogram model was constructed. The discrimination, calibration, and clinical utility of the model were evaluated using ROC curve, calibration curve, and decision curve analysis (DCA). A total of 63 septic patients were finally enrolled in the study, including 23 patients in the SIMI group and 40 patients in the non-SIMI group. The APACHE II score, alanine aminotransferase (ALT), aspartate aminotransferase (AST), N-terminal pro-brain natriuretic peptide (NT-proBNP), cTnI, MB isoenzyme of creatine kinase (CK-MB), IL-18, and MIF were all higher in the SIMI group compared to the non-SIMI group (all P<0.05). There were no statistically significant differences in demographic data, other laboratory indicators, and echocardiographic parameters between the two groups. Correlation analysis revealed a positive correlation between MIF and downstream inflammatory factor IL-18 and APACHE II score in septic patients (r values were 0.523 and 0.556, respectively, both P<0.05). Among echocardiographic indicators, MIF was negatively correlated with left ventricular ejection fraction (LVEF; r=-0.265, P<0.05), while there was no significant correlation between MIF and left ventricular posterior wall thickness at end-diastole or left atrial diameter at end-diastole (both P>0.05). ROC curve analysis revealed that both MIF and IL-18 possessed predictive value for 28-day death in septic patients [the area under the ROC curve (AUC) and 95% confidence interval (95%CI) were 0.745 (0.563-0.933) and 0.751 (0.614-0.892), respectively], and the combined prediction of the two had an AUC of 0.784 (95%CI was 0.629-0.940), with a sensitivity of 78.6% and a specificity of 79.6%. Multivariate Logistic regression analysis revealed that an elevated SOFA score [odds ratio (OR)=1.381, 95%CI was 1.067-1.787, P=0.014], increased IL-18 (OR=1.000, 95%CI was 1.000-1.001, P=0.023), elevated MIF (OR=1.000, 95%CI was 1.000-1.000, P=0.036), and decreased oxygenation index (OR=0.989, 95%CI was 0.978-1.000, P=0.046) were independent risk factors for 28-day death in patients with sepsis. Based on these variables, a nomogram model for predicting 28-day death in septic patients was constructed. ROC curve analysis indicated that the AUC of the nomogram model for predicting 28-day death in septic patients was 0.894 (95%CI was 0.766-1.000). Further analysis revealed that the model's C-index reached 0.894, and both the calibration curve and DCA curve suggested good discriminatory power, calibration capability and clinical utility of the model. MIF can serve as a sensitive biomarker for early identification of SIMI, and the combined detection of MIF and IL-18 can enhance the predictive efficacy of prognosis for sepsis patients.",
"42563799": "ID: 42563799\nTitle: Steroids for Drug-Resistant Seizures and Prolonged Stroke-Like Episode in a Patient With Sturge-Weber Syndrome: A Case Report.\nAbstract: Sturge-Weber syndrome (SWS) brain involvement has been associated with impairments in the blood-brain barrier (BBB) and microglial activation within involved cortical regions. Acute neurological crises, including seizures, stroke-like episodes, and/or significant headaches, are common in these patients. This report describes in detail an adolescent with SWS and acute drug-resistant status epilepticus, headache, and stroke-like episode who improved clinically when treated with high-dose steroids. Review of medical records identified two other patients previously treated with steroids for acute neurological symptoms. A 13-year-old boy with SWS brain involvement presented with fever, headache, seizures, and right-sided weakness. Brain magnetic resonance imaging (MRI) revealed characteristic findings of SWS. The patient was placed on continuous electroencephalogram that showed findings consistent with electrographic status epilepticus. Seizures were refractory to multiple anti-seizure medications as well as to an intravenous midazolam drip. A repeat MRI of the brain documented a significant increase in leptomeningeal enhancement with associated gyral edema and sulcal effacement. Steroid therapy with methylprednisolone and prednisone improved his status epilepticus and stroke-like symptoms, including resolution of seizures and marked improvement in his hemiparesis. This patient suggests a potential role for inflammation-targeted therapies in individuals with SWS brain involvement who present with prolonged neurological crises. Two other patients with SWS brain involvement who were treated with high-dose steroids in the context of acute neurological episodes also support the need for future clinical and preclinical research to validate this approach.",
"42563870": "ID: 42563870\nTitle: \"Fifth-day fits\" revisited: A literature review of benign idiopathic neonatal seizures and comparison with KCNQ2- and KCNQ3-associated benign familial epilepsy syndromes.\nAbstract: Benign idiopathic neonatal seizures (BINS), colloquially referred to as the \"fifth-day fits,\"\u00a0is a clinical neonatal epilepsy syndrome associated with early, spontaneous resolution of seizures and favorable developmental outcome. Although this disease entity was first described over four decades ago, the etiopathogenesis remains unknown, and it is unclear if the syndrome represents a single, cohesive disorder or a common manifestation of various unrelated neonatal neurological disturbances. As such, there are no standardized approaches to diagnostic workup and management. Benign familial neonatal seizures (BFNS) is a well-characterized genetic syndrome associated with KCNQ2 and KCNQ3 pathogenic variants, which also manifests clinically with self-resolving seizures in the neonatal period. While it remains unclear if there is any shared pathogenesis between these two disorders, the exceedingly similar phenotypic presentations and natural history raise the question of whether consensus management approaches used in genetic BFNS can also be applied to BINS. Here, we present a topical and historical review of BINS and BFNS literature and propose specific treatment recommendations based on extrapolation of limited existing clinical data.",
"42563962": "ID: 42563962\nTitle: Human interferon-\u03c9: an underappreciated type I interferon.\nAbstract: Interferon-\u03c9 (IFN-\u03c9) is a member of the human type I interferon family that has historically been overshadowed by IFN-\u03b1 and IFN-\u03b2. Recent human \"natural perturbations\", most notably selective neutralization of IFN-\u03c9 by autoantibodies in life-threatening viral infections, have renewed interest in this comparatively understudied cytokine and indicate that its antiviral activity may not always be fully compensated in defined clinical settings. This renewed focus has prompted reassessment of its single-gene organization, distinct antigenicity, intermediate receptor-binding kinetics, cellular sources, and regulatory mechanisms. In parallel, thymus-centered tolerance disorders, including autoimmune regulator (AIRE) deficiency, additional inborn errors of immune tolerance, and acquired \"sick thymus\" states, establish anti-IFN-\u03c9 autoantibodies as a stable, high-penetrance immunophenotype linking tolerance failure to durable cytokine-directed autoimmunity. Beyond antiviral defense, multi-omic studies in lupus-spectrum disease suggest tissue- and compartment-specific IFN-\u03c9 signals within broader type I interferon programs, yet endogenous IFN-\u03c9 remains rarely quantified with ligand-level resolution. This Review integrates current knowledge of IFN-\u03c9 from molecular regulation to human disease. Further progress will require subtype-resolved measurement, direct comparison with other type I interferons under matched conditions, and human genetic studies testing whether rare IFNW1 variants contribute to severe viral disease.",
"42563993": "ID: 42563993\nTitle: Metabolic reprogramming orchestrates microglial fate in cerebral ischemia-reperfusion injury: a spatiotemporal immunometabolic perspective.\nAbstract: Cerebral ischemia-reperfusion injury (CIRI) represents a critical pathological cascade that paradoxically exacerbates neurological damage following revascularization therapy for acute ischemic stroke (AIS). The pathogenesis of CIRI is intricately linked to dysregulated neuroinflammation, with microglia-the resident innate immune cells of the central nervous system-serving as central orchestrators of this response. Emerging evidence indicates that microglia undergo profound metabolic reprogramming encompassing glucose metabolism, the tricarboxylic acid (TCA) cycle, fatty acid metabolism, and NAD+ homeostasis, which fundamentally dictates their functional polarization and consequent neuroinflammatory outcomes. Rather than existing as discrete pro-inflammatory versus reparative phenotypes (classically referred to as M1/M2), microglia exhibit a continuum of activation states with distinct metabolic signatures that evolve dynamically across spatiotemporal dimensions following CIRI. Here, we systematically synthesize current knowledge on the core molecular mechanisms underlying microglial metabolic reprogramming, including the ACOD1/itaconate pathway, the glycolysis-OxPhos balance, and NAMPT-mediated NAD+ homeostasis. We critically examine the intricate crosstalk between these metabolic pathways and neuroinflammatory signaling cascades, revealing how metabolic checkpoints serve as integrative nodes that decode microenvironmental cues into functional outputs. Building on this mechanistic foundation, we evaluate emerging intervention strategies targeting metabolic reprogramming, stratified by intervention modality and translational readiness, with emphasis on agents in active clinical development. Finally, we identify prevailing challenges-including spatiotemporal heterogeneity, cell-specific targeting requirements, and clinical translation barriers-and outline future directions integrating single-cell omics, systems biology approaches, and advanced delivery systems. This comprehensive analysis aims to provide a refined conceptual framework and highlight promising therapeutic avenues for mitigating CIRI through strategic modulation of microglial immunometabolism.",
"42563994": "ID: 42563994\nTitle: Axonal pathfinding during the development of the nervous system.\nAbstract: Guidance of axons sprouting from maturing neuroblasts, during intermediate trajectories and in seeking target neurons for synaptogenesis, is a fundamental developmental process in central nervous system\u00a0maturation. Axons but not dendrites sprout from neuroblasts during migration. The growth cone of the axonal tip projects constantly changing multiple veils and spikes (lamellipodia and filopodia) that contain microtubules, actin microfilaments, mitochondria, endosomes, and membrane receptor proteins. They are sensitive to changes in ionic calcium flux and may be impeded by perinatal hyper- or hypoglycemia. The growth of axonal membranes occurs mainly at the growth cone. Neurofilaments appear in the axonal tip as it approaches its target. Growth cones are attracted to or repelled by various extracellular matrix molecules that guide them, such as netrins and glycoproteins. Numerous genes are involved, some specific for only certain projections. Neurotransmitters later to be secreted are recognized in growing axons before their synthesis. Axonal fascicles are enveloped by extracellular keratan sulfate that ensures that fascicles contain axons of similar origin and destination and whose neurons secrete the same transmitter. Near their targets, axonal tips may ramify to form synapses on more than one neuron. Transitory pioneer axons provide supplementary mechanical guides to permanent axonal trajectories. Thalamus and olfactory bulb contain axonless neurons with dendrodendritic synapses. Chromaffin neurons of neural crest origin develop no neurites. Most cerebral malformations involve aberrant axonal pathfinding; in holoprosencephaly, keratan sulfate abnormally ensheathes individual axons. Axonal pathfinding to near or distant target neurons is primordial for synaptic circuitry subserving normal and abnormal neurological functions including epilepsy.",

Here, we employed integrated multi-omics approaches to systematically dissect the role of alternative polyadenylation (APA) and piRNA-mediated regulation in psoriasis pathogenesis. We performed transcriptome-wide association studies (TWAS) combined with Mendelian randomization to identify causal susceptibility genes. Long-read sequencing was used to characterize APA landscapes in 15 healthy controls and 10 psoriasis patients. Single-cell RNA sequencing was performed on lesional tissues from 4 patients to define cell-specific expression patterns. Small RNA sequencing was conducted to profile piRNA regulation in LPS + IFN-\u03b3-polarized THP-1 macrophages following TDRKH knockdown. Integrating multi-tissue genetic validations across GTEx, eQTLGen, and FinnGen datasets, we identified TDRKH as a robust psoriasis susceptibility gene (PPH4 > 0.92). TDRKH exhibited significant APA alterations in psoriatic PBMCs, with preferential usage of the distal polyadenylation site leading to 3'UTR lengthening (PDI = -0.574). Reporter gene assays confirmed that the long 3'UTR isoform conferred approximately 3-fold greater mRNA stability (t\u00bd = 6.9\u00a0h vs. 2.3\u00a0h). Single-cell RNA sequencing of psoriatic skin (4 patients, 17,734 cells) identified 17 cell types and 10 macrophage/myeloid subpopulations using marker gene-based annotation with TDRKH excluded from feature selection. TDRKH expression was highest in IL-23-producing macrophages (IL23A+IL1B+), which were selectively enriched in lesional tissue. TDRKH knockdown in LPS + IFN-\u03b3-polarized THP-1 macrophages altered piRNA expression profiles, reduced pro-inflammatory surface markers (CD80, CD86, HLA-DR), and attenuated IL6 and IL1B expression, supporting a functional role of the TDRKH-piRNA axis in macrophage inflammatory activation. Our findings reveal a previously unrecognized post-transcriptional regulatory network involving APA and piRNA that governs macrophage-driven inflammation. The discovery of the TDRKH-piRNA axis provides novel mechanistic insights into psoriasis and establishes a potential therapeutic target.",

The nuclear receptor NR1D1 is pivotal in regulating circadian rhythms and plays a significant role in inflammation and metabolism. This study investigates the therapeutic effects and mechanisms of the NR1D1 agonist SR9009 on obesity-related UC. We established a mouse model of obesity-induced UC utilizing a high-fat diet alongside dextran sulfate sodium (DSS). 32 male C57BL/6 mice were divided into four groups: control (DZ), high-fat diet (GZ), obesity associated UC model group (UC), and SR9009 intervention group (JD), with eight mice each. We evaluated body weight, blood lipids, colonic tissue alterations, IL-1\u03b2, IL-18, macrophage polarization, and NR1D1 expression levels. Mice in the UC group demonstrated significantly elevated body weight, spleen index, TG, CHOL and inflammatory markers (P\u00a0<\u00a00.01). Pathological scores of colonic tissues increased markedly (P\u00a0<\u00a00.001), with a rise in M1 macrophages (CD68+) and a decline in M2 macrophages (CD206+) (P\u00a0<\u00a00.001). NR1D1 expression was notably downregulated (P<0.01). Post-SR9009 intervention, the JD group showed significantly reduced serum TG and CHOL levels (P\u00a0=\u00a00.001, 0.011), IL-1\u03b2 and IL-18 (P<0.001), improved colonic pathology (P\u00a0<\u00a00.001), a decrease in M1 macrophages, an increase in M2 macrophages, and an enhanced M1/M2 ratio (P<0.001). SR9009 mitigates intestinal inflammation in obesity associated UC by activating NR1D1, potentially modulating NF-\u03baB-related signaling, and modulating macrophage polarization (suppressing M1 and enhancing M2). These findings propose a novel strategy for targeting NR1D1 in the treatment of obesity-related ulcerative colitis.",

This study used truffles from Huidong County, Sichuan Province as the research subject, setting four storage temperatures: -4\u00a0\u00b0C, 0\u00a0\u00b0C, 4\u00a0\u00b0C, and 20\u00a0\u00b0C. Physiological indicators such as postharvest decay rate, relative electrical conductivity, and respiration rate were measured. These were combined with metabolomic analysis to screen for differential metabolites and metabolic pathways. The results showed that truffles stored at -4\u00a0\u00b0C have a relatively low rot rate and are better suited for storage(P\u00a0<\u00a00.05). However, the relative electrical conductivity and MDA content of truffles stored at -4\u00a0\u00b0C were significantly higher than those in the 0\u00a0\u00b0C and 4\u00a0\u00b0C treatment groups (P\u00a0<\u00a00.05). The SDH activity of truffles stored at 0\u00a0\u00b0C and 4\u00a0\u00b0C was significantly higher than that of the -4\u00a0\u00b0C group in the later stages (P\u00a0<\u00a00.05). CAT activity was significantly higher in the -4\u00a0\u00b0C group than in the other groups during the first 21 days of storage(P\u00a0<\u00a00.05). Metabolomic analysis revealed that the -4 \u00b0C vs 4 \u00b0C group had the most differential metabolites in the positive ion mode, with pathways such as branched-chain amino acid metabolism, glutathione metabolism, and steroid biosynthesis being significantly enriched (P\u00a0<\u00a00.05). This study systematically reveals the effects of storage temperature on truffle preservation and its mechanisms, providing a theoretical basis for postharvest preservation of truffles.",

For decades, treatment was limited to lifestyle interventions. The years 2024 and 2025 marked a paradigm shift with the first-ever FDA approvals of pharmacologic agents for MASH. This comprehensive narrative review synthesizes the evidence for newly approved and emerging pharmacotherapies for MASH, addressing the mechanisms of action, pivotal clinical trial data, efficacy, safety profiles, and place in therapy for resmetirom and semaglutide. It also discusses key agents including pioglitazone, saroglitazar, and vitamin E, and evaluates the non-invasive testing (NIT) toolkit-including FIB-4, VCTE, shear wave elastography, MRE, and ELF-in the context of a structured, risk-stratified clinical algorithm. Resmetirom (Rezdiffra), a THR-\u03b2 agonist, achieved MASH resolution in 26%-30% versus 10% placebo and fibrosis improvement in 24%-26% versus 14% placebo at 52 weeks in the MAESTRO-NASH trial. Semaglutide 2.4 mg (Wegovy) demonstrated a 28.7% delta over placebo in MASH resolution in the ESSENCE trial. Pioglitazone has additional evidence for reducing the FIB-4 index in real-world studies. Saroglitazar, a PPAR-\u03b1/\u03b3 dual agonist approved in India, has shown significant reductions in ALT, liver fat, and metabolic parameters in Phase 2 studies and is advancing to Phase 2b. Shear wave elastography is a clinically important alternative to VCTE for fibrosis staging, particularly in patients with obesity, and offers value in resolving discordant FIB-4/VCTE results. The approval of resmetirom and semaglutide marks a new era in MASH management. A risk-stratified algorithmic approach using NITs guides patient selection, with liver biopsy reserved for specific clinical scenarios. The therapeutic landscape is rapidly evolving, with saroglitazar and combination approaches representing key frontiers.",

This retrospective study enrolled 85 patients with pathologically confirmed pulmonary metastases. After radiomic feature extraction, the cohort was divided into a training set (n=59) and an independent test set (n=26) at a 7:3 ratio via stratified sampling. Data were processed with Z-score normalization, variance thresholding and PCA (45 principal components). Five classifiers were constructed: LR, linear SVM, RF, XGBoost and LightGBM. Model stability and performance were assessed by 5-fold stratified cross-validation and independent test validation. The 45 principal components accounted for 99.92% of cumulative variance. LR showed optimal performance, with a test AUC of 0.9821, classification accuracy of 84.62%, and a mean cross-validation AUC of 0.9606 (95% CI: 0.8887-0.9895). The small training-test AUC difference (0.0179) indicated no severe overfitting. SVM ranked second (test AUC\u00a0=\u00a00.9405), while XGBoost and RF exhibited significant overfitting and LightGBM underfitting. The model's decision relied on key texture features; only GLSZM non-uniformity differed significantly between groups, consistent with their pathophysiological characteristics. The PCA-reduced and regularization-optimized LR model has excellent generalization, stability and clinical interpretability in differentiating pulmonary metastases from breast and colorectal cancers. This study preliminarily highlights the potential of LR in high-dimensional small-sample scenarios, and provides a foundational methodological reference for future large-scale multicenter diagnostic research.",
"42564117": "ID: 42564117\nTitle: Effects of immunosuppression on tracheal mucosal responses after infection with Mycoplasma gallisepticum in vaccinated and unvaccinated chickens.\nAbstract: Vaccination is the most common method used to control infection caused by Mycoplasma gallisepticum in chickens. However, concurrent immunosuppression may compromise vaccine efficacy. This study investigated the effect of immunosuppression induced by either chicken anaemia virus (CAV) or infectious bursal disease virus (IBDV), administered prior to or following vaccination with the M. gallisepticum live vaccine strain ts-304 (Vaxsafe MG304), on tracheal host responses to subsequent challenge with virulent M. gallisepticum. Tracheal responses were assessed by genome-wide transcriptional profiling in these groups and compared across unvaccinated-unchallenged, unvaccinated-challenged, vaccinated-unchallenged and vaccinated-challenged groups that had not been exposed to CAV or IBDV. Immunosuppression resulted in significant differences in tracheal transcriptional responses compared to immunocompetent groups, irrespective of the timing of infection with CAV or IBDV. Differences in transcription were more pronounced in the IBDV-infected groups than the CAV-infected groups. Functional interrogation of differentially transcribed genes revealed adverse effects of M. gallisepticum on extracellular and intracellular signalling, cell communication, cellular actin dynamics, formation of the cellular cytoskeleton, and cellular metabolic pathways in the tracheal mucosa of immunosuppressed groups. In addition, there were indications of down-regulation of both innate and adaptive immune responses, including cytokine signalling, antigen processing presentation, and immune cell receptor signalling in the immunosuppressed groups. Specifically, findings indicated that infection with CAV impaired pro-inflammatory and adaptive T-cell responses in the tracheal mucosa. The findings implied that the primary immune response induced post-vaccination and the secondary immune response induced post-challenge with virulent M. gallisepticum were both affected by infection with these two viruses. Coupled with previous observations of reduced antibody titres against M. gallisepticum, and increased rates of recovery of virulent M. gallisepticum in both CAV- and IBDV-infected groups, the significant transcriptional changes detected in the current study highlighted the roles of both cell-mediated (CMI) and humoral immunity (HI) in vaccine-induced protection, as CAV mainly affects CMI and IBDV mainly affects HI. These findings will assist in identifying the mechanisms underlying the reduced efficacy of live attenuated mycoplasma vaccines in immunosuppressed animals.",

Klebsiella pneumoniae is an opportunistic Gram-negative pathogen that causes severe infections, particularly in susceptible individuals. This study investigated the effects of cigarette smoke extract (CSE) on K. pneumoniae virulence-associated traits and host immune responses. Three multidrug-resistant, extended-spectrum \u03b2-lactamase-producing clinical K. pneumoniae isolates were exposed to CSE. Bacterial growth, virulence gene expression (mrkA, luxS, and AcrB), biofilm formation, antimicrobial susceptibility, macrophage invasion, neutrophil phagocytosis, and cytokine responses in THP-1-derived macrophages were evaluated using microbiological, molecular, and cell culture assays. High concentrations of CSE (\u226525%) suppressed bacterial growth, whereas 5-10% CSE had minimal effects. Exposure to 10% CSE significantly upregulated mrkA, luxS, and AcrB expression. Biofilm formation increased by 20.8-37.0%, and minimum inhibitory concentrations of ciprofloxacin and tigecycline increased two-fold following CSE exposure. CSE enhanced bacterial invasion of THP-1 macrophages and impaired neutrophil phagocytosis, reducing bacterial uptake by 17.8% and 29.9% after 30 and 60 min, respectively. Furthermore, CSE promoted a pro-inflammatory response characterized by increased TNF-\u03b1 and IL-1\u03b2 expression and reduced IL-10 expression across multiple time points. CSE enhances the virulence potential of K. pneumoniae while disrupting innate immune defenses and immune regulation. These findings demonstrate a harmful synergy between cigarette smoke and bacterial infection that may contribute to the increased susceptibility and severity of respiratory infections observed in smokers.",

To assess structural post-tuberculosis lung sequelae and their association with respiratory health status in adults from northern Peru. We conducted a prospective analytical cross-sectional study of 106 adults previously treated for pulmonary tuberculosis and evaluated at least 6\u202fmonths after treatment completion. Structural sequelae were defined as fibrosis, bronchiectasis, or residual cavitary changes on non-contrast high-resolution chest CT. Dyspnea severity was assessed with the modified Medical Research Council scale and respiratory health status with the St George's Respiratory Questionnaire. Associations were examined using robust Poisson, ordinal logistic, and linear regression models. Structural sequelae were present in 40.6% of participants, while multidimensional respiratory burden reached 59.4%. Older age was associated with structural sequelae (aPR 1.020, 95% CI 1.010-1.040), whereas longer time since treatment completion was inversely associated (aPR 0.950, 95% CI 0.920-0.980). Structural sequelae were associated with greater dyspnea severity (OR 7.680, 95% CI 3.110-20.120) and higher SGRQ scores (\u03b2 11.410, 95% CI 6.200-16.610). Structural post-tuberculosis lung sequelae were common and were associated with worse respiratory health status, supporting structured respiratory follow-up after treatment.",

These diseases are commonly associated with insulin resistance and abnormal lipid metabolism, and increasing evidence indicates that immune imbalance and chronic low-grade inflammation are involved in their development. Natural polysaccharides are important bioactive components derived from plants, fungi, algae, and other natural sources. Current evidence supporting their beneficial effects in metabolic diseases is predominantly preclinical, mainly from cell-based and animal studies, while clinical evidence remains limited and heterogeneous. Natural polysaccharides have attracted interest as candidate bioactive compounds because some preparations have shown immunomodulatory and metabolic regulatory activities in experimental models. Their activities are closely related to structural features, including monosaccharide composition, glycosidic linkage types, molecular weight, branching structure, and chemical modification. Current preclinical evidence suggests that natural polysaccharides may alleviate metabolic inflammation by regulating macrophage polarization, suppressing pro-inflammatory cytokine production, modulating MAPK, NF-\u03baB, AMPK, and related signaling pathways, and reshaping the gut microbiota-immune axis. These compounds may help improve several pathological features of metabolic disorders, such as insulin resistance, abnormal lipid metabolism, inflammatory injury, and tissue dysfunction. However, several challenges still limit their translation, including unclear structure-activity relationships, inconsistent preparation standards, limited bioavailability, and insufficient well-designed clinical trials. Therefore, this review provides an overview of the natural sources, structural properties, immunomodulatory actions, and therapeutic prospects of natural polysaccharides in metabolic diseases, with a focus on their involvement in immune regulation and metabolic inflammation.",

Within necrotic femoral heads, immune cells, particularly macrophages, undergo phenotypic reprogramming. This phenotypic shift in macrophages, along with their interactions with other cell types-including osteoclasts, mesenchymal stem cells, and endothelial cells-collectively mediates disease progression. However, targeted immunotherapeutic strategies remain poorly defined. In this context, the present study reviews recent literature and provides a comprehensive overview of the immunological landscape of macrophages in osteonecrosis of the femoral head (ONFH). It summarizes current knowledge on macrophage immune reprogramming, intercellular interactions with neighboring cells (such as mesenchymal stem cells, osteoclasts, and vascular endothelial cells), and the cellular composition of immune cells (including neutrophils, B cells, and T cells) in ONFH. Furthermore, it explores the potential application of biomaterials developed through various strategies for ONFH treatment. Emerging evidence indicates that the direction of macrophage polarization and their intercellular interactions with diverse cell types (e.g., mesenchymal stem cells, osteoclasts, and vascular endothelial cells), together with the infiltration of immune cells (such as neutrophils, B cells, and T cells), collectively influence the progression of ONFH. On this basis, therapeutic strategies targeting macrophage polarization and immune cell activation are proposed, with a particular focus on biomaterials possessing diverse physicochemical properties, thereby offering insights to facilitate the clinical translation of ONFH treatments.",

Female DBA/2 mice were subjected to a concomitant tumor model in which SL2 lymphoma cells were injected subcutaneously (SC) to establish a primary tumor, followed by intraperitoneal (IP) SL2 challenge to induce secondary tumors. Peritoneal immune cells were analyzed by flow cytometry 4 days after IP challenge. Absolute cell numbers were calculated from total viable cell recovery. To assess functional antitumor activity, CD11b+F4/80+ peritoneal macrophages were isolated by magnetic separation and adoptively transferred into na\u00efve mice together with SL2 cells. In additional experiments, mice received repeated IP injections of SL2 cells. Non-parametric statistical tests were used for data analysis. Prolonged survival in mice with secondary IP SL2 tumors was associated with pronounced alterations in peritoneal immune composition. Flow cytometric analysis revealed a marked accumulation of small peritoneal macrophages (SPMs) and dendritic cells (DCs) in mice with secondary IP tumors. Absolute counts of SPMs (CD11bintF4/80int) and DCs (CD11c+) were significantly increased in the secondary IP tumor group, with a positive, not statistically significant, correlation between these population. In contrast, mice with primary IP tumors showed expansion of CD11c-CD11b- F4/80- cells, which may include SL2 tumor cells, reduced numbers of B lymphocytes (CD19+) and large peritoneal macrophages (LPMs) (CD11bhiF4/80hi) and an increased number of CD11blowF4/80int cells. Adoptive transfer of peritoneal macrophages from mice with secondary IP tumors did not prolong survival. Repeated IP administration of SL2 cells was associated with improved survival in mice bearing SC tumors in 3 of 5 mice, compared with 1 of 5 mice in the SC tumor-only group, although this difference did not reach statistical significance. Prolonged survival of DBA/2 mice with secondary IP SL2 tumors is associated with a distinct peritoneal immune landscape characterized by accumulation of SPMs and DCs. While macrophages alone were insufficient to control tumor growth, repeated IP tumor challenge suggested a trend toward systemic antitumor activity. Collectively, these findings highlight SPMs and DCs as prominent cells associated with survival benefit in this model.",

In recent years, the gut microbiota has emerged as an important regulator of cardiovascular pathophysiology, largely through the production of bioactive metabolites that act on distant organs. This review summarizes the major classes of gut microbiota-derived metabolites involved in cardiovascular disease, with particular emphasis on trimethylamine N-oxide, short-chain fatty acids, phenylacetylglutamine, bile acids, and tryptophan-derived metabolites. We discuss how these metabolites influence endothelial dysfunction, immune activation, lipid handling, platelet reactivity, cardiac remodeling, gut barrier integrity, and blood pressure regulation through interconnected signaling pathways. We further examine their disease-specific relevance in atherosclerosis, heart failure, hypertension, and coronary artery disease/acute coronary syndrome. In addition, we evaluate current translational strategies targeting microbial metabolism, including dietary modulation, probiotics and prebiotics, fecal microbiota transplantation, and selective inhibition of microbial enzymes. Rather than viewing individual metabolites as uniformly harmful or protective, we propose that cardiovascular risk is better understood as the net consequence of interacting microbial metabolic pathways within specific host contexts. This metabolite-centered framework may help refine biomarker development, risk stratification, and pathway-guided interventions in cardiovascular medicine.",
"42564178": "ID: 42564178\nTitle: Metabolic immune checkpoints in cancer: how tumor-derived metabolites shape immunotherapy resistance.\nAbstract: Immune checkpoint blockade has transformed cancer therapy, yet many tumors remain intrinsically resistant or acquire resistance after initial response. Increasing evidence indicates that this failure is not determined solely by PD-1, PD-L1, CTLA-4, or T-cell exhaustion, but also by metabolically suppressive states within the tumor microenvironment. Tumor-derived metabolites can function as metabolic immune checkpoints by limiting effector immune activity, promoting regulatory or myeloid suppressive compartments, and weakening immunotherapy efficacy. This mini review summarizes recent experimental evidence showing how lactate, adenosine, tryptophan-derived metabolites, and nucleotide-derived metabolites shape immune escape and resistance to immune checkpoint blockade. Lactate links tumor glycolysis to Treg recruitment, impaired T-cell function, and lactylation-associated therapeutic resistance. The CD73-adenosine axis suppresses CD8+ T cells and natural killer cells while reinforcing regulatory and myeloid immune programs. Tryptophan-derived metabolites extend beyond the classical IDO1-kynurenine-AhR pathway to involve non-classical checkpoints such as Siglec-15 and broader kynurenine/indole/serotonin networks. Emerging evidence further identifies nucleotide-derived UDP signaling as a driver of macrophage-mediated immunosuppression. Finally, we discuss how targeting metabolic checkpoints in combination with immune checkpoint blockade may improve therapeutic responses. Defining the spatial and cellular contexts of metabolite-mediated immune suppression may enable more precise strategies to overcome immunotherapy resistance.",
"42564204": "ID: 42564204\nTitle: Targeting macrophage-mediated TGF-\u03b2/BMP signaling in ankylosing spondylitis: from inflammation to pathological bone formation.\nAbstract: Ankylosing spondylitis (AS) is a chronic, immune-mediated disease characterized by inflammatory arthritis and pathological new bone formation, ultimately leading to spinal fusion and functional impairment. Despite effective suppression of inflammation by biologic agents targeting cytokines such as TNF-\u03b1 and IL-17A, radiographic progression often continues, highlighting a critical dissociation between inflammatory activity and structural damage. The literature suggests that macrophage polarization and the TGF-\u03b2/BMP signaling axis collectively constitute a critical nexus linking inflammation to aberrant osteogenesis in AS. Moreover, it details how the unique entheseal microenvironment-shaped by biomechanical stress, hypoxia, and a distinct cytokine milieu-drives macrophages toward a spectrum of pro-osteogenic phenotypes through a mechano-inflammatory feedback loop. After that, polarized macrophages, in turn, serve as pivotal cellular engineers that locally activate and sustain TGF-\u03b2/BMP signals through proteolytic cleavage and acidic remodeling of the ECM. This self-amplifying loop directly orchestrates endochondral ossification at ligamentous insertion sites, culminating in syndesmophyte formation and spinal ankylosis. Therapeutically, this mechanistic understanding highlights promising avenues for disease modification beyond conventional anti-inflammatory strategies. Targeting macrophage polarization states or disrupting the TGF-\u03b2/BMP activation cascade may offer dual benefits-suppressing both inflammation and structural progression-and pave the way for genuine disease-modifying therapies in AS.",

It is rare for a patient with cluster headache to have coexisting multiple headache disorders and experience unusual triggers. A 53-year-old male with a 14-year history of episodic cluster headache presented with his third cluster episode. He exhibited strictly unilateral left orbital/periorbital/temporal drilling pain [Visual Analogue Scale (VAS) 9-10/10], ipsilateral conjunctival injection, lacrimation, rhinorrhea, and agitation. Notably, during the second episode (2015), left maxillary sinusitis was identified and surgically treated, leading to immediate and complete headache resolution. During the current episode, physical examination revealed left temporal artery nodularity and tenderness-raising suspicion of giant cell arteritis. However, the erythrocyte sedimentation rate and C-reactive protein levels were within the normal range. Brain MRI/MRA revealed only nonspecific white matter changes, along with suspected wall thickening of the left superficial temporal artery. The patient declined temporal artery ultrasound, high-resolution MRI, and biopsy. In accordance with clinical guidelines, the patient was administered comprehensive treatment for cluster headache. Given the suspicion of giant cell arteritis, empirical prednisone was also initiated at a dose of 1\u2005mg/kg/day. By day 3 of treatment, attack frequency had reduced from daily to 3-4 times per week, pain intensity decreased from VAS 10/10 to 3-6/10, attacks resolved within 30\u2005min either spontaneously or after zolmitriptan, and temporal artery nodules had markedly diminished. Interestingly, during follow-up, the patient reported that ingestion of soy sauce or vinegar consistently triggered an unusual throat discomfort followed by headache within 30\u2005min, whereas avoidance of these substances resulted in no attacks. The patient's strict avoidance of soy sauce and vinegar led to a marked reduction in headache frequency over a short period, ultimately resulting in a complete absence of headache episodes. He remains under follow-up. This case highlights an unusual concurrence of episodic cluster headache with suspected giant cell arteritis and possible sinusitis-related headache in a single patient. The potential role of soy sauce and vinegar as triggers for cluster headache warrants further validation with extended follow-up and a larger case series.",

We analyzed single-cell RNA sequencing data from GEO (GSE148466), NSCLC-related data from TCGA, and gene expression data from GEO (GSE50081). A 9-gene TIL-related risk score model (HLA-DRA, NPC2, PRPF38B, PABPC1, ENO1, ANXA2, LGALS1, S100A10, SRGN) was constructed using LASSO regression, with its prognostic value assessed via Kaplan-Meier and ROC analyses and external validation. Immune infiltration and regulatory factors were analyzed using TISIDB, pathway associations via GSVA and GSEA, and functional roles of key genes (HLA-DRA, NPC2, PRPF38\u00a0B) validated using RT-qPCR, Western blotting, and co-culture assays. TILs were abundant in both smoking and non-smoking NSCLC samples. The 9-gene risk model effectively stratified patients by survival, with high-risk patients showing poorer outcomes and enriched tumor-promoting immune features and pathways. High-risk scores were associated with increased M0 macrophages, activated NK cells, and elevated immune checkpoints. Overexpression of HLA-DRA, NPC2, and PRPF38\u00a0B inhibited NSCLC cell proliferation, migration, and invasion, while enhancing apoptosis and suppressing M2 macrophage polarization. This study establishes a TIL-based prognostic risk model for NSCLC and identifies HLA-DRA, NPC2, and PRPF38\u00a0B as potential immune-regulatory therapeutic targets with tumor-suppressive functions, providing new insights for NSCLC precision immunotherapy.",

Among these, the gut microbiota has emerged as a critical determinant of neurodevelopmental trajectories. Through its involvement in immune modulation, metabolic signaling, and neural communication, the microbiota-gut-brain axis (MGBA) exerts a pervasive influence on brain maturation and function. A growing body of evidence indicates that early-life disruptions of microbiota composition-commonly referred to as dysbiosis-are associated with an increased risk of NDDs, including autism spectrum disorder (ASD), attention-deficit/hyperactivity disorder (ADHD), and epilepsy. These disruptions are frequently driven by environmental exposures such as antibiotic use, cesarean delivery, dietary patterns, and psychosocial stress. Despite the expanding recognition of these associations, current therapeutic strategies aimed at restoring microbiota balance, including probiotics and fecal microbiota transplantation, have yielded inconsistent and often transient results. In this context, Vagus Nerve Stimulation (VNS), particularly in its non-invasive forms (nVNS), has emerged as a promising approach capable of modulating environmental exposures through the host-centered regulatory mechanisms of the MGBA. By influencing autonomic tone, activating the cholinergic anti-inflammatory pathway, and modulating neurotransmitter systems, nVNS may restore microbiota homeostasis while simultaneously improving neurodevelopmental outcomes. This article provides a comprehensive and integrative review of the mechanistic, preclinical, and clinical evidence supporting the role of nVNS as a microbiota-modulating intervention. We further discuss its potential as a safe, cost-effective and promising therapeutic strategy for neurodevelopmental disorders, with a particular emphasis on pediatric populations.",

A patient presented with a pruritic erythematous plaque on the left chest wall that progressively enlarged over one year. Skin biopsy and subsequent pathology consultation demonstrated invasive adenocarcinoma involving the dermis and subcutaneous tissue. Immunohistochemistry supported PCAC (CK7+, GATA3+, AR strongly positive, and patchy GCDFP-15 positivity), and a left axillary lymph node confirmed metastatic carcinoma. Whole-body 18F-FDG PET/CT revealed extensive metastatic disease involving multiple lymph node stations, lung, pleura, and multiple bones, precluding upfront surgery. The patient received systemic therapy with serplulimab (300 mg intravenously every 3 weeks) plus anlotinib (10 mg orally once daily, days 1-14 of a 21-day cycle) and concomitant bicalutamide (50 mg orally once daily). After two cycles, CT imaging showed partial reduction in pulmonary nodules and mediastinal lymphadenopathy, with thinning of the chest wall lesion and resolution of a small pleural effusion. Subsequent follow-up demonstrated continued clinical improvement of the chest wall lesion and sustained radiological disease control, without new rapidly progressive visceral lesions. No clinically significant adverse events or notable laboratory toxicities were observed during treatment and follow-up. This case illustrates a feasible combination approach for widely metastatic PCAC using PD-1 blockade, anti-angiogenic therapy, and anti-androgen treatment, with clinical and radiographic improvement and favorable tolerability during follow-up. Prospective data are needed to clarify patient selection and define optimal systemic strategies for advanced PCAC.",

The order Burkholderiales is an underexplored yet highly promising group of microorganisms, characterized by a broad ecological distribution and considerable potential for application in sustainable agricultural systems. In this study, we aimed to isolate and characterize a potential biocontrol strain belonging to Burkholderiales, with the goal of contributing to eco-friendly agricultural practices and mining previously unexploited secondary metabolites. A novel bacterial strain, Pseudoduganella sp. D-3-1, was isolated from Cangma Mountain and characterized to possess potent antifungal activity and a high iron-chelating capacity. Whole-genome sequencing revealed that its complete genome spans 6,875,892 bp and encodes 6035 predicted coding sequences (CDSs), including a complete violacein biosynthesis pathway. Genome mining uncovered a diverse array of secondary metabolite biosynthetic gene clusters (BGCs), notably a non-ribosomal peptide synthetase (NRPS) gene cluster, designated the pseudodubactin cluster, which encodes a catecholate-type siderophore structurally related to turnerbactin. Through high-resolution electrospray ionization mass spectrometry (HR-ESI-MS), gene knockout, heterologous expression, and bioinformatics analysis, four turnerbactin analogs (1-4) were identified for the first time from Pseudoduganella sp., including two novel compounds: pseudodubactin A (2), and pseudodubactin B (4). Additionally, HR-ESI-MS analysis detected two uncharacterized siderophores, designated as compound 5 and compound 6, that are structurally distinct from the turnerbactin analogs. These findings indicate that Pseudoduganella sp.

Paired synovial biopsies from 12 patients with RA were obtained before and 8 weeks after initiation of adalimumab. Immune-cell infiltrates (CD163+ macrophages, CD3+ lymphocytes) and expression of osteoprotegerin (OPG), receptor activator of nuclear factor \u03baB (RANK), and its ligand (RANKL) were assessed by immunohistochemistry. In vitro, the effect of adalimumab on RANKL and OPG expression in SaOS-2 cells (\u00b1\u00a0TNF-\u03b1) was evaluated by western blotting. Its effect on osteoclastogenesis and bone resorption were examined using CD14+ monocyte-derived macrophages cultured with RANKL and M-CSF. Adalimumab treatment led to a marked clinical improvement, with median DAS28 decreasing from 5.4 to 3.1. Semiquantitative analysis of synovial biopsies revealed a significant decrease in CD163+ macrophages, while CD3+ T-cells remained unchanged. The RANKL/OPG ratio decreased significantly, which was accompanied by increased OPG expression in synovial tissue. In vitro, adalimumab significantly decreased RANKL expression and the RANKL: OPG ratio in TNF-\u03b1 primed SaOS-2 cells, while also modulating pro-osteoclastogenic cytokines. In osteoclast assays, adalimumab inhibited macrophage-derived osteoclast differentiation and suppressed bone resorption under both low and high RANKL conditions. Adalimumab decreased synovial macrophage infiltration while it modulates pro-osteoclastogenic cytokines and inhibits osteoclastogenesis. These combined effects explain how TNF-\u03b1 blockade ameliorates joint inflammation and prevents structural damage.",

When all three components of Virchow's triad converge simultaneously in a previously healthy individual, the clinical consequences can be devastating and the diagnostic workup both urgent and complex. We report a 58-year-old man with no prior medical history who presented with progressive dyspnea and was found to have bilateral pulmonary emboli, large mobile thrombi in both the left atrium and left ventricle, and extensive systemic arterial thrombosis culminating in left lower extremity ischemia. Imaging revealed an underlying heart failure with reduced ejection fraction with an estimated ejection fraction of 20% and concurrent atrial flutter. Comprehensive hypercoagulable workup including antiphospholipid antibody syndrome evaluation was negative. The patient required emergent left lower extremity embolectomy at the initial hospital, transfer to a tertiary center for repeat femoral-femoral bypass that subsequently thrombosed, and ultimately a left below-knee amputation. He was discharged on apixaban. Subsequent atrial fibrillation/flutter ablation achieved durable sinus rhythm. Genetic testing revealed a pathogenic TTN (titin) variant, providing a unifying etiology for his dilated cardiomyopathy. Serial echocardiography at 3 months demonstrated resolution of all intracardiac thrombi; repeat imaging at 6 months showed substantial left ventricular ejection fraction recovery to 42%. This case illustrates that new-onset heart failure with reduced ejection fraction with concurrent atrial flutter can serve as a sufficient and independent driver of catastrophic multi-territory thromboembolism without additional systemic hypercoagulable disease. It also demonstrates that with aggressive guideline-directed medical therapy, rhythm control, and sustained anticoagulation, meaningful ventricular recovery is achievable even after severe initial dysfunction. TTN-related cardiomyopathy should be considered in otherwise unexplained dilated cardiomyopathy, and genetic counseling should be offered to first-degree relatives.",

We report a case of Type 1 Kounis syndrome in a 51-year-old male who presented with acute chest discomfort, diaphoresis, and dyspnea following ingestion of diclofenac and ondansetron. Initial evaluation revealed transient anterior wall ST-segment elevation (V2-V5) with normal cardiac biomarkers and no regional wall motion abnormalities. The patient was initially managed for acute coronary syndrome; however, rapid resolution of symptoms and electrocardiographic changes, along with normal echocardiography and coronary angiography findings, suggested an alternative diagnosis. Clinical features, including GI symptoms without cutaneous manifestations, further supported an atypical allergic presentation. He was treated with intramuscular epinephrine, antihistamines, and corticosteroids, with prompt clinical improvement. A diagnosis of Type 1 Kounis syndrome secondary to drug-induced coronary vasospasm was established. This case underscores the importance of early recognition of Kounis syndrome in acute coronary presentations, particularly in the absence of biomarker elevation and obstructive coronary disease.",

However, the fate of DOM under the combined influence of light and microorganisms-especially in northern steppe lakes-remains poorly understood. Here, we integrated ultrahigh-resolution mass spectrometry (FT-ICR MS) and high-throughput sequencing in a microcosm experiment using water from Hulun Lake, the largest arid steppe lake in northern China, to compare the molecular transformation of endogenous algal-derived DOM (ADOM) and exogenous livestock manure-derived DOM (MDOM). Treatments included dark controls, light-only, microbial-only, and light-microbial coupling. Using high-resolution mass spectrometry and multi-group structural equation modeling, our results demonstrate that light regulates microbial processing of DOM through source-dependent mechanisms. Photodegradation suppressed the bioavailability of ADOM by 4.9%, largely due to combined substrate competition and reactive oxygen species (ROS) stress on key bacterial degraders. In contrast, light synergistically enhanced the bioavailability of MDOM by 5.4% through substrate facilitation. Molecular-level analysis revealed that lignin-like molecules from different sources exhibit distinct responsiveness to photochemical and microbial processing, which emerged as the key mechanistic driver for the contrasting degradation patterns. Microbial co-occurrence networks further linked specific bacterial taxa to DOM component turnover and ROS sensitivity. These findings highlight the central role of light in modulating DOM balance and source-sink dynamics in arid boreal lakes, providing novel, mechanism-based insights into the biogeochemical cycling of DOM in lake ecosystems.",

Neuroinflammation represents a significant maladaptive outcome after rmTBI. Persistent innate and adaptive immune cell responses can lead to neurodegeneration and deficits in brain development. Therefore, a deeper understanding of the early dynamics of peripheral immune cell infiltration after pediatric rmTBI is critical for the development of effective treatment. We hypothesize that pediatric rmTBI alters neuroinflammation through T cell infiltration. We used wild-type (C57BL/6) and T cell knockout (TCR\u03b2-/- \u03b4-/-) mice to test this hypothesis. We developed a pediatric postnatal day 21 rmTBI model, with three consecutive subconcussive impact acceleration injuries separated in time by 1 week. After inducing rmTBI in juvenile mice, we observed a progressive infiltration of macrophages, CD8+, and CD4+ T cells into the brain parenchyma, which increased with repeated injury. Furthermore, neuroinflammation in the white matter was detected when we analyzed the lateral corpus callosum (CC). Since increased infiltration of CD4+ and CD8+ T cells was detected, we utilized TCR\u03b2-/- \u03b4-/- mice to further explore the role of T cells on neuroinflammation after pediatric rmTBI. We observed a reduction in the infiltration of pro-inflammatory macrophages and decreased neuroinflammation in the lateral CC. Overall, our findings highlight the significant role of T cell infiltration in the modulation of neuroinflammation following rmTBI in the developing brain, suggesting that they may serve as potential therapeutic targets for managing neuroinflammation following pediatric brain injuries.",

The present study identified fibro/adipogenic progenitors (FAPs) as the primary source of CCL2 in acutely injured muscle, where the pro-inflammatory subcluster of FAPs expanded rapidly and expressed the highest level of CCL2. FAP-specific deletion of Ccl2 largely abolished CCL2 production by acutely injured muscle, reducing monocyte/macrophage infiltration and impairing muscle regeneration. In vitro, the CCL2 expression by both mouse and human FAPs was induced by danger signal-containing muscle homogenates through Toll-like receptor signaling. The CCL2 expression by mouse FAPs was also induced by infiltrating neutrophils, partly through their secretion of pro-inflammatory cytokines. Our findings suggest an important immune sentinel role for FAPs, as they sense muscle damage, produce CCL2 to recruit inflammatory monocytes, and promote injury repair.",
"42564436": "ID: 42564436\nTitle: Array comparative genomic hybridisation in haematological malignancies: A comprehensive review.\nAbstract: Haematologic malignancies have diverse and complex genomic abnormalities, and the correct identification is essential for making the appropriate diagnosis, providing a prognosis, and planning treatment. Improved array comparative genomic hybridisation (array CGH) can provide high-resolution, genome-wide copy number variation detection, and overcomes conventional cytogenetic limitations. The aim of this study is to determine the role of array CGH in characterising genomic aberrations of haematologic malignancies, focusing on technical advantages, added diagnostic values, and implications for disease reclassification and precision medicine. A comprehensive literature search of PubMed, Embase, Web of Science, and Scopus was conducted to identify studies evaluating the diagnostic performance and clinical utility of array CGH in haematologic cancers. Array CGH detects genomic alterations at kilobase-level resolution and reveals additional abnormalities in approximately 30% of cases with normal results by conventional cytogenetics. It improves molecular subtyping, identifies novel prognostic marker and, when combined with single nucleotide polymorphism arrays, enables detection of uniparental disomy and copy-neutral loss of heterozygosity, thereby enhancing diagnostic yield. Array CGH detects up to 90% of known genomic abnormalities in haematologic malignancies, and its integration with other genomic platforms will considerably enhance diagnostic precision and clinical care for haematopoietic neoplasms. This review emphasises the important role of array CGH's greater sensitivity to clinically relevant copy number changes compared to routine cytogenetics. Clinical applications of array CGH support precision oncology, especially when combined with single nucleotide polymorphism array or next-generation sequencing technologies.",
"42564443": "ID: 42564443\nTitle: A low-dose immunotherapy targeting Fc gamma Receptors and heparan sulfate proteoglycan to impact myeloid cells and control cancers with diverse immunosuppressive profiles.\nAbstract: Myeloid cells play a key role in cancer-associated immunosuppression because their accumulation and reprogramming inhibit antitumor responses and support tumor growth. To modulate their activity, we targeted Fc\u03b3 receptors (Fc\u03b3Rs), which are broadly expressed in myeloid subsets. Since low-affinity Fc\u03b3 receptor IIb (Fc\u03b3RIIb) mediates inhibitory signaling, we designed an immunotherapy active at a low dose to limit binding to Fc\u03b3RIIb while retaining interaction with higher-affinity Fc\u03b3Rs. We engineered an Fc-based fusion protein, whose activity is potentiated by its ability to engage both Fc\u03b3Rs and a coreceptor, Heparan Sulfate Proteoglycan (HSPGs). This immunotherapy, named Fc-T54, combines an HSPG-ligand, named T54, with human IgG1-Fc. Compared with Fc, Fc-T54 displayed superior binding to Fc\u03b3 receptor IIa (Fc\u03b3RIIa), Fc\u03b3 receptor IIIa (Fc\u03b3RIIIa) and enhanced interactions with human leukocytes, including neutrophils, B-lymphocytes, as well as with monocytes, and dendritic cells (DCs) within peripheral blood mononuclear cells. Functionally, Fc-T54 increased monocyte/macrophage and B-cell numbers, reduced neutrophil abundance, and boosted DC activation in both the human and murine systems. Subcutaneous administration of low-dose Fc-T54 - or its murine surrogate - inhibits tumor growth in immune-deserted and immune-excluded mouse models and synergizes with anti-PD-1 therapy in an immune-inflamed model. Tumor microenvironment analysis in the bladder cancer model revealed that the immunotherapy decreased the proportion of granulocytic myeloid-derived suppressor cells while increasing CD8+ T cells and natural killer cells, promoting a microenvironment more prone to tumor control. This Fc\u03b3R/HSPG-engaging immunotherapy, administered subcutaneously, offers a novel approach to modulate the myeloid compartment and improve outcomes for ICI-resistant, deserted/excluded tumors, and for inflamed tumors when used in combination regimens.",
"42564504": "ID: 42564504\nTitle: Adverse exposure burden, NMR metabolomics, and risk of incident abdominal aortic aneurysm.\nAbstract: The cumulative impact of multidomain adverse exposures on abdominal aortic aneurysm (AAA) risk and the underlying metabolic pathways remain insufficiently understood. We analyzed 304,482 UK Biobank participants free of aortic aneurysm at baseline. Twenty-six exposures were grouped into five domains to derive domain specific and overall exposure scores. Associations with incident AAA were assessed using Cox models. To explore potential metabolic pathways, we applied a two stage NMR metabolomics framework combining multivariable linear regression, metabolite specific Cox models, and a 10-fold cross validated elastic net Cox model to generate a metabolite score. Mediation analyses and XGBoost models were also performed. During a mean follow up of 14.9 years, 1,671 participants developed AAA. A higher overall exposure score was associated with an increased risk of incident AAA (per SD increase: HR, 1.08; 95% CI, 1.07-1.11). Among domain specific scores, the socioeconomic, social psychology, and lifestyle scores were independently associated with AAA, whereas the environmental pollution and living environment scores were not. Current smoking showed the strongest association among individual exposures (HR, 7.95; 95% CI, 6.81-9.27). Overall exposure burden was associated with broad metabolomic perturbations, and a 13-metabolite score was significantly associated with AAA (per SD increase: HR, 1.38; 95% CI, 1.35-1.41), mediating 5.78% of this association. Adding exposure and metabolite scores improved prediction beyond clinical factors alone. Greater multidomain adverse exposure burden was associated with higher incident AAA risk, partly through metabolic signatures related to inflammation and lipoprotein metabolism, and may provide incremental value for AAA risk stratification.",
"42564509": "ID: 42564509\nTitle: High expression of USP15 affects tumor progression and immune infiltration in hepatocellular carcinoma.\nAbstract: Ubiquitin-specific protease 15 (USP15) is closely associated with the occurrence and progression of hepatocellular carcinoma (HCC). However, its role in shaping the immune landscape of HCC remains unclear. The expression levels, proportions, and spatial distributions of USP15 and specific immune cell subsets in HCC tissues were evaluated using multiplex immunohistochemistry (mIHC). In the tumor parenchyma of HCC tissues, the infiltration of immune cells, particularly natural killer (NK) cells, was significantly reduced (p<0.05). Further analyses revealed that USP15 expression levels were significantly associated with clinical stage and other clinicopathological parameters (p<0.05). In particular, NK cell infiltration was significantly correlated with N stage, M stage, and overall tumor-node-metastasis (TNM) stage (p<0.05). USP15 contributes to the establishment of an immunosuppressive tumor microenvironment in HCC by inhibiting T cell and NK cell infiltration, facilitating programmed death-ligand 1 (PD-L1)-mediated immune evasion, and enhancing macrophage recruitment. These findings indicate that USP15 may serve as a potential therapeutic target for HCC.",
"42564594": "ID: 42564594\nTitle: Impact of a Structured MRI Reporting Template on the Completeness of Primary Rectal Cancer Staging Reports: A Retrospective Audit.\nAbstract: High-resolution pelvic magnetic resonance imaging (MRI) is essential for local staging of primary rectal carcinoma and for communicating surgically relevant risk factors before multidisciplinary treatment planning. Free-text MRI reports may describe the primary tumor but may inconsistently document key management-relevant findings, including mesorectal fascia and circumferential resection margin status, depth of extramural spread, extramural vascular invasion, lateral pelvic lymph nodes, and low rectal sphincter complex involvement. This retrospective audit assessed whether use of a structured MRI reporting template was associated with improved completeness of primary rectal cancer staging reports. This retrospective audit included 60 pelvic MRI reports performed for suspected or biopsy-proven primary rectal carcinoma at a tertiary care radiology department. Thirty consecutive reports prepared before template implementation were assigned to the free-text reporting group, and 30 reports prepared after template implementation were assigned to the structured reporting group. Reports were assessed using a predefined checklist of essential MRI staging elements, including tumor location, distance from the anal verge, craniocaudal tumor length, circumferential tumor position, relationship to the anorectal junction and anterior peritoneal reflection, MRI T category, depth of extramural spread, mesorectal fascia/circumferential resection margin status, extramural vascular invasion, mesorectal nodes, tumor deposits, lateral pelvic lymph nodes, sphincter complex involvement, levator ani involvement, adjacent organ invasion, and final MRI-based risk summary. The primary and only measured outcome was report completeness. The mean completeness score was higher in the structured reporting group than in the free-text group, with mean scores of 91.3% and 58.6%, respectively. Structured reports showed more complete documentation of several clinically important staging domains that were inconsistently recorded in free-text reports, including mesorectal fascia/circumferential resection margin relationship, depth of extramural spread, extramural vascular invasion, lateral pelvic nodal assessment, and low rectal sphincter complex assessment. Structured reports also more frequently included a concise MRI-based risk summary integrating tumor level, T stage, nodal status, margin risk, extramural vascular invasion, and anticipated surgical relevance. No formal statistical hypothesis testing was performed; therefore, these findings should be interpreted descriptively rather than inferentially. Implementation of a structured MRI reporting template was associated with higher report completeness in this descriptive retrospective audit of primary rectal cancer staging reports. The structured template was associated with more complete documentation of clinically relevant reporting elements, particularly margin status, extramural spread, extramural vascular invasion, lateral pelvic nodes, and low rectal sphincter complex involvement. However, report completeness was the only measured outcome, and no formal statistical testing was performed. Further studies with statistical testing, reviewer blinding, and assessment of diagnostic accuracy or clinical outcomes are needed.",

"42564688": "ID: 42564688\nTitle: Three-dimensional photoacoustic tomography with ultrasound localization priors.\nAbstract: Three-dimensional photoacoustic tomography (3D-PAT) enables noninvasive structural and functional imaging with optical absorption contrast and ultrasonic detection depth. However, its spatial resolution is limited by acoustic diffraction, and incomplete detection geometry can substantially degrade image fidelity and quantitative accuracy. Here, we present a ULM-guided model-based reconstruction framework, termed 3D-PAULMprior that incorporates sub-diffraction vascular priors from concurrent ultrasound localization microscopy (ULM) into 3D photoacoustic reconstruction. The method uses weighted regional Laplacian regularization to integrate high-resolution vascular information into the inverse problem, thereby enhancing vascular sharpness, suppressing limited-view artifacts, and improving blood oxygen saturation estimation. We validated 3D-PAULMprior using numerical simulations, tissue-mimicking phantoms, and in vivo mouse brain imaging. Compared with conventional reconstruction, 3D-PAULMprior reduced the system blurring, increased contrast-to-noise ratio, and enhanced structural similarity. In vivo, 3D-PAULMprior enhanced the delineation of the vascular structures that were poorly resolved in conventional reconstructions and produced more spatially confined sO\u2082 maps. These results establish 3D-PAULMprior as a robust multimodal reconstruction strategy for high-resolution structural and functional photoacoustic imaging.",
"42564737": "ID: 42564737\nTitle: Report on the 13th international workshop on the CCN family of genes and inaugural ARBIOCOM conference, Nice, France.\nAbstract: The 13th International Workshop on the CCN Family of Genes, held in Nice as part of the inaugural ARBIOCOM World Conference, brought together investigators with diverse research backgrounds, disciplines, and expertise. Building on the long-standing mission of the International CCN Society and the expanding ARBIOCOM initiative, the meeting highlighted the growing importance of interdisciplinary exchange in accelerating discovery in normal and pathological signaling networks. Scientific sessions featured presentations by renowned speakers and early-career investigators alike, creating a highly collaborative environment that fostered discussion of emerging concepts and translational opportunities. Among the major themes, this joint conference-meeting highlighted \"hot\" research topics such as the nuclear and extracellular roles of CCN proteins in regulating gene expression, tissue development and remodeling, stem cell differentiation and therapies, and disease initiation and progression. Presentations on skeletal biology emphasized how extracellular matrix proteins and matricellular factors shape bone, cartilage, and connective tissue development and pathology, whereas vascular sessions revealed new mechanistic links between extracellular cues, endothelial remodeling, macrophage-driven vessel regression and vascular smooth muscle homeostasis. Other talks extended the relevance of new signaling molecules in intestinal regeneration, hepatic inflammation, metabolic control, and cancer progression, illustrating the broad biological reach of these pathways. The meeting also emphasized the value of integrating new model systems, advanced single-cell approaches, and functional in vivo studies to uncover mechanisms that were previously unknown. Collectively, the scientific sessions and discussions identified and filled key knowledge gaps and generated new hypotheses with strong potential for future discoveries. By connecting established expertise with complementary scientific perspectives, this meeting provided a fertile platform for cross-pollination of ideas and highlighted several avenues for future research aimed at developing novel diagnostic and therapeutic strategies and tools."

The first hypothesis focuses on GPR146, a regulator of systemic cholesterol and phagocytic receptor expression, which may mitigate MASH-associated inflammatory phenotypes [ID: 42554945, 42564069]. The second hypothesis explores Piezo1-mediated mechanical stimulation to rescue efferocytosis in tumor-associated macrophages by leveraging non-glycolytic energy pathways and bypassing metabolic suppression [ID: 42564178, 38838160]. Both paths identify crucial intersecting biological bridges, specifically cholesterol metabolism and HIF1-alpha metabolic reprogramming [ID: 42550891]."
