Sorafenib, a multikinase inhibitor of RAF/VEGFR/PDGFR, can suppress these pathways, but its clinical utility is limited by hydrophobicity, toxicity, and poor tumor penetration. We engineered hyaluronic acid-coated niosomes encapsulating sorafenib (SOR@Nio/HA) to enable CD44-targeted delivery to OSCC cells. SOR@Nio/HA displayed a mean hydrodynamic diameter of 177\u00b18 nm (PDI=0.23-0.26) and high encapsulation efficiency (86.34%), with pH-responsive release (45% at pH=5.5 and 30% at pH=7.4, in 24 hr). In CAL27 cells, SOR@Nio/HA significantly enhanced cytotoxicity versus free sorafenib, lowering IC50 from 11.8\u00b11.1 \u00b5M to 5.2\u00b10.9 \u00b5M (P<0.01), and increased Annexin V/PI-defined apoptosis relative to controls. qRT-PCR showed suppression of NF-\u03baB targets, with COX-2 and MMP-9 reduced to 0.35-fold and 0.32-fold of the control, respectively, alongside a pro-apoptotic shift in the BAX/BCL-2 axis. Collectively, these data indicate that SOR@Nio/HA improves intracellular delivery and potentiates sorafenib's antitumor activity by CD44-mediated uptake and inhibition of NF-\u03baB-driven inflammatory and invasive programs. HA-guided niosomal sorafenib warrants in vivo validation as a selective nanotherapeutic strategy for OSCC."

Celastrol (Cel)'s oral translation is limited by poor bioavailability and lack of lesion-specific targeting. To overcome these barriers, we constructed a hyaluronic acid (HA)-functionalized platform featuring dual enzyme/ROS-triggered release and CD44-mediated active targeting (HA@Cel/NPs) for treating ulcerative colitis (UC), colitis-associated colorectal cancer (CAC), and colon cancer. HA@Cel/NPs were fabricated using \u03b2-cyclodextrin and 4-(hydroxymethyl) phenylboronic acid as dual-responsive linkers. Physicochemical properties, drug release profiles, cellular uptake, anti-inflammatory activity, macrophage polarization, and anticancer activity were systematically evaluated in vitro. In vivo biodistribution and therapeutic efficacy were assessed in UC, CAC, and colon cancer mouse models, with anti-PD-L1 combination therapy in the colon cancer setting. HA@Cel/NPs exhibited uniform size (76.87 \u00b1 2.65 nm, PDI 0.166 \u00b1 0.012), stayed stable for 14 days, and achieved ~71% Cel release under high H2O2/\u03b1-amylase conditions within 8\u00a0h. The nanocarriers enhanced cellular uptake and promoted M1-to-M2 macrophage polarization in inflamed macrophages, while inducing potent CT26 cell apoptosis. Orally administered HA@Cel/NPs alleviated UC severity and suppressed CAC progression, with significantly reduced tumor burden. In colon cancer, intravenous HA@Cel/NPs combined with intraperitoneal anti-PD-L1 significantly boosted CD8\u207a and CD4\u207a T cell infiltration and effectively eradicated established tumors compared with HA@Cel/NPs monotherapy. HA@Cel/NPs offer a versatile, dual-route platform that bridges inflammation management and cancer immunotherapy, distinguishing itself from single-mechanism or single-disease nanocarriers."

"abstract_text": "ID: 42586120\nTitle: Hyaluronic acid-based nanocarriers for cancer therapy: molecular design, biointerface mechanisms, and translational challenges.\nAbstract: Hyaluronic acid (HA) has emerged as a versatile structural material and targeting ligand within cancer drug delivery systems (DDSs) and nanomedicine applications, owing to its biodegradability, tunable chemistry, and strong affinity for CD44 and related receptors. This review examines studies published from 2019 to 2026, with emphasis on high-quality research in leading journals, and connects the structural parameters of HA with quantitative drug delivery efficiency and therapeutic performance. The major HA-based carrier systems, including micelles, liposomes, polymeric nanoparticles, metal-organic frameworks, and electrospun fiber systems, are critically analyzed in relation to HA molecular weight, degree of substitution, and ligand density, as well as their effects on hydrodynamic size, zeta potential, colloidal stability, and cellular uptake. Across these studies, the most effective designs generally feature nanoscale dimensions that balance circulation and tumor penetration while maintaining near-neutral or slightly negative surface potentials to minimize nonspecific interactions, highlighting the importance of rational physicochemical design for improving therapeutic performance.
Quantitative models of drug release, together with in vitro potency indices such as half-maximal inhibitory concentration (IC50) and combination index, as well as in vivo pharmacokinetic and efficacy indicators including half-life, area under the curve (AUC), and tumor-to-organ ratio, demonstrate how the configuration of HA influences therapeutic selectivity and systemic safety. To improve the rigor and reproducibility of future studies, this review further proposes a concise reporting framework integrating materials characterization, biological evaluation, and animal experiments, while highlighting the current limitations in standardization and cross-study comparability.
In conclusion, this review summarizes the current design principles of HA-based nanocarriers while critically discussing the remaining challenges, including CD44 heterogeneity, microenvironmental competition, and the lack of standardized evaluation strategies. Together, these perspectives provide practical guidance for the rational design, comparative evaluation, and clinical translation of next-generation HA-based nanocarriers.

A targeted drug delivery system (HLC) was constructed using hyaluronic acid (HA) nanomicelles co-loaded with lactate oxidase (LOX) and copper-doped carbon dots (CuCDs). Combined with \u03b1-PD-L1, a synergistic antitumor strategy integrating lactate metabolic regulation, cuproptosis, and immune activation was established. HLC achieves targeted accumulation through specific binding between HA and CD44 receptors on tumor cells. It directionally releases LOX and CuCDs in the acidic TME via pH-responsive properties. LOX efficiently clears lactate and elevates pH, blocking the HIF-1\u03b1/PD-L1 pathway to reverse immunosuppression. It also generates H2O2 in situ to provide substrates for Cu-mediated Fenton-like reactions, enhancing cuproptosis. In vitro experiments confirm that HLC promotes dendritic cell maturation and drives M2-type macrophage polarization toward the M1 phenotype. In vivo studies using CT26 tumor-bearing mouse models show that HLC combined with 808\u202fnm laser and \u03b1-PD-L1 significantly inhibits primary and distant tumor growth. It remodels the antitumor immune microenvironment with favorable biosafety. This study elucidates the synergistic mechanism between lactate metabolic regulation and cuproptosis, establishes an association between lactate level and cuproptosis sensitivity, and provides a novel strategy and experimental basis for combined cancer immunotherapy with important clinical translation value."

Kidney diseases represent a major global health burden, often progressing to chronic complications due to the limited efficacy and poor selectivity of conventional therapies, which are frequently associated with systemic toxicity. Accordingly, the development of targeted drug delivery systems is essential to improve therapeutic outcomes. In this study, advanced quatsomes were developed as a kidney-targeted nanosystem to enhance the delivery of curcumin, a natural polyphenolic compound with potent antioxidant and nephroprotective properties. The system was composed of di-dodecyl-dimethyl-ammonium bromide (DDAB), cholesterol, limonene, hyaluronic acid (HA) and surfactants, and was fabricated using the ethanol injection method. A 23 factorial design was employed to optimize formulation variables, including DDAB:cholesterol ratio, limonene:drug ratio, and surfactant concentration. The optimized formulation (desirability = 0.950) exhibited high entrapment efficiency (87.80%), nanosized vesicles (120.55\u00a0nm), and a positive surface charge (+38.30\u00a0mV). Transmission electron microscopy confirmed spherical morphology, while in-vitro release studies demonstrated a biphasic profile. The formulation also showed good physicochemical stability and enhanced antioxidant activity. Mechanistically, passive targeting via nanoscale size and cationic charge facilitated interaction with the glomerular filtration barrier and mesangial uptake, while limonene improved vesicle deformability. HA functionalization further enabled CD44-mediated active targeting. In vivo, the optimized system significantly reduced serum creatinine and blood urea nitrogen levels in a cisplatin-induced nephrotoxicity model, with histological evidence of renal protection. Overall, the developed quatsomes demonstrate promising potential as an efficient renal-targeted nanocarrier."

Here, we developed a hyaluronic acid (HA)-coated MEL-based polymersome (PMHA) for CD44-targeted codelivery of MEL and celecoxib (CXB). MEL was incorporated into the vesicular membrane, whereas CXB was loaded into the hydrophobic domain. PMHA showed a hydrodynamic diameter of 265.5\u2009\u00b1\u20091.6\u2009nm, a zeta-potential of -21.14\u2009\u00b1\u20091.1\u2009mV, a CXB encapsulation efficiency of 70.81\u2009\u00b1\u20094.18%, and a drug loading capacity of 12.87\u2009\u00b1\u20091.92%. In lipopolysaccharide (LPS)-stimulated RAW 264.7 macrophages, anti-CD44 antibody blocking reduced Alexa Fluor 647-labeled PMHA uptake by approximately 37.5%, supporting HA-CD44-mediated internalization. PMHA reduced MEL-associated cytotoxicity and hemolytic activity and enabled pH-responsive CXB release. Codelivery of MEL and CXB suppressed cyclooxygenase-2\u2009(COX-2) and tumor necrosis factor-\u03b1 (TNF-\u03b1) expression, with combination index (CI) values of 0.48 and 0.67, respectively. These findings support further evaluation of PMHA as a macrophage-targeted anti-inflammatory nanoplatform."

"abstract_text": "ID: 42435660\nTitle: Molecular glycoengineering of carbohydrate-functionalized nanocarriers for receptor-mediated targeted drug delivery in cancer.\nAbstract: Carbohydrate-functionalized nanocarriers have moved from a decorative surface-modification concept to a molecular drug-delivery strategy in which glycan ligands, polysaccharide shells and synthetic glycopolymers are engineered to negotiate tumor recognition, receptor clustering, endocytosis, intracellular trafficking and stimulus-triggered release. The field is scientifically attractive because cancer cells and tumor-associated stromal cells remodel their glycocalyx, overexpress selected carbohydrate-recognizing receptors and display altered metabolic demand; however, the translation of glycoengineered nanomedicine remains limited by low tumor delivery efficiency, heterogeneous receptor density, competitive off-target uptake by liver and macrophages, batch-to-batch variation in ligand density and insufficient quantitative reporting. This review re-frames carbohydrate-mediated cancer drug delivery as an evidence-weighted design problem. It integrates receptor-density data, particle-size boundaries, ligand-density ranges, release-rate targets, in vitro uptake metrics, pharmacokinetic endpoints and preclinical efficacy readouts into a quantitative framework. Special attention is given to hyaluronic acid-CD44, galactose/GalNAc-ASGPR, mannose-CD206, sialylated glycan-siglec/selectin, beta-galactoside-galectin and glucose/GLUT-related approaches, with emphasis on what the available data can and cannot prove. The central conclusion is that molecular glycoengineering is most defensible when carbohydrate chemistry is linked to measurable receptor engagement, competitive inhibition, uptake kinetics, intracellular drug exposure and statistically stronger antitumor benefit rather than to generic claims of active targeting. The framework explicitly links anomeric configuration, glycosidic linkage, branching, sulfation/acetylation, epitope display and glycan-protein hydration to receptor-specific pharmacological outcomes, thereby shifting the emphasis from general nanomedicine performance to carbohydrate structure-activity relationships required for a carbohydrate-chemistry readership."

"abstract_text": "ID: 42421100\nTitle: The endometriosis-adenomyosis spectrum: shared pathophysiology and microenvironment-driven disease divergence.\nAbstract: Endometriosis and adenomyosis are common gynecologic disorders associated with dysmenorrhea, chronic pelvic pain, and infertility. Although they share several molecular features, the mechanisms by which endometrium-derived tissues develop distinct pathological phenotypes in different tissue environments remain incompletely understood. This review summarizes shared and divergent pathogenic mechanisms, focusing on lesion-specific microenvironments. This narrative review was based on a PubMed literature search from the year of the first publication through December 2025 using terms related to endometriosis, adenomyosis, mitochondrial function, oxidative stress, fibrosis, mechanical stress, and calcium signaling. Both disorders develop in the context of repetitive tissue injury, estrogen-dependent repair responses, chronic inflammation, oxidative stress, and mitochondrial dysfunction. However, differences in lesion location and microenvironment appear to drive distinct pathological phenotypes. In superficial peritoneal endometriosis and ovarian endometrioma, mitochondrial adaptation primarily supports hypoxia tolerance, oxidative stress responses, angiogenesis, cellular survival, and metabolic reprogramming. In contrast, deep infiltrating endometriosis and adenomyosis are characterized by fibrosis, extracellular matrix remodeling, tissue stiffening, and adaptation to mechanical stress. In adenomyosis, mitochondrial regulation of calcium homeostasis, smooth muscle contractility, reactive oxygen species production, and TGF-\u03b2-related fibrotic signaling may play important roles in disease progression. We propose a proliferation-fibrosis divergence model in which common pathogenic stimuli are integrated through mitochondria-dependent responses to distinct local microenvironments. Mitochondria may act as central regulators linking hypoxic adaptation, inflammation, metabolism, fibrosis, and mechanotransduction, thereby influencing whether disease progression favors proliferative expansion or fibrotic remodeling. This framework may provide a basis for future mechanism-based precision therapeutic strategies."

This study examined the effects of TSS on fecundity and endometriosis-like lesions during pregnancy in a murine model of endometriosis. Endometriosis model mice were divided into four groups: Sham operation\u202f+\u202fcontrol diet (Sham/Cont), Sham operation\u202f+\u202f3% TSS diet (Sham/TSS), Endometrium dispersion\u202f+\u202fcontrol diet (End/Cont), and Endometrium dispersion\u202f+\u202f3% TSS diet (End/TSS). Mating was initiated one day after surgery, and females were sacrificed on postpartum day 3. Endometriosis-like lesion size, inflammatory cytokine levels, and reproductive outcomes were evaluated. Time to delivery tended to be shorter in the End/TSS group than in the End/Cont group (median: 23.5 vs. 27 days), although the difference was not statistically significant. The maximum lesion diameter in the End/TSS group was significantly smaller compared to the End/Cont group (median: 4.54\u202fmm vs. 7.76\u202fmm, p\u202f=\u202f0.044). Concentrations of the inflammatory cytokines MIP-3\u03b1 and IL-17A were significantly lower in the End/TSS group (MIP-3\u03b1: 14.54 [12.91, 18.98] vs. 25.26 [16.81, 48.58] pg/mg protein, p\u202f=\u202f0.019, IL-17A: 10.00 [9.05, 18.76] vs. 19.06 [16.75, 82.81] pg/mg protein, p\u202f=\u202f0.019). TSS administration reduced endometriosis-like lesion size and was associated with suppression of Th17-related inflammatory mediators in a murine model of endometriosis. Consequently, the administration of TSS tended to shorten the time to pregnancy. These findings suggest that TSS may exert immunomodulatory effects within endometriosis lesions and could represent a potential non-hormonal therapeutic approach during the peri-conceptional period."

The central question this review seeks to answer is: are steroidal alkaloids - nitrogenous plant-derived steroids with a unique structure - a mechanistically sensible, non-hormonal alternative that can simultaneously target the inflammatory, fibrotic and epigenetic drivers of endometriotic lesion persistence, while preserving fertility and avoiding systemic hormonal suppression? A growing body of evidence points to non-hormonal molecular networks including immune dysregulation, angiogenesis, and resistance to apoptosis as drivers of lesion persistence. These molecular disturbances are associated with treatment resistance and limit the long-term efficacy of hormone-based therapies. This review synthesises recent mechanistic advances that describe the non-hormonal signalling pathways that maintain endometriotic lesions, with a specific emphasis on NF-\u03baB-mediated sterile inflammation, inflammasome activation, PI3K/Akt/mTOR-dependent survival signalling, Hedgehog-driven fibrosis and epigenetic repression of progesterone receptor expression. Steroidal alkaloids are critically reviewed as multitarget modulators suppressing inflammatory signalling, inhibiting invasive and fibrotic remodelling, and restoring apoptotic sensitivity in this pathophysiological context, without direct systemic oestrogen deprivation. Structural determinants of steroidal alkaloid activity, including glycosylation status, nitrogen topology and configuration of the steroidal scaffold, are discussed in the context of pathway selectivity, pharmacokinetics and toxicity. Preclinical in vitro and in vivo evidence is critically reviewed in the context of key translational limitations such as bioavailability constraints, narrow therapeutic index and teratogenic risk from developmental pathway inhibition. This review highlights steroidal alkaloids as a mechanistically rational, non-hormonal approach to target lesion persistence and fibrosis in endometriosis, integrating molecular, pharmacological and structural insights, and outlines the major hurdles that must be overcome for clinical translation. The main objective of this review is to address a specific unanswered question: can steroidal alkaloids with their multitarget pharmacology offer a biologically coherent, non-hormonal strategy for the treatment of endometriosis that goes beyond oestrogen deprivation to target the molecular machinery of lesion survival, fibrosis and immune dysregulation. This question is addressed by reviewing the nonhormonal signalling networks that support ectopic lesions, the structural and pharmacokinetic properties of steroidal alkaloids that are relevant to these pathways, and the translational challenges that need to be addressed for clinical translation."

In this study, we designed a hyaluronic acid-based prodrug system, HA-Ns-Dox, that integrates receptor-mediated cellular uptake with intracellular glutathione (GSH)-responsive activation. A doxorubicin (Dox) prodrug modified with a 2-nitrobenzenesulfonyl (Ns) group was synthesized and subsequently conjugated to hyaluronic acid (HA) via click chemistry to generate HA-Ns-Dox with both CD44-targeting capability and GSH-responsive activation properties. HA-Ns-Dox formed stable nanosized assemblies in aqueous solution and exhibited high stability under low-GSH conditions mimicking extracellular environments, whereas concentration-dependent activation of Dox was observed under high-GSH conditions mimicking intracellular reductive environments. In vitro studies demonstrated that HA-Ns-Dox was selectively internalized into the CD44-high human breast cancer cell line MDA-MB-231, accompanied by intracellular prodrug activation and nuclear accumulation of Dox. In contrast, cellular uptake and activation were minimal in the CD44-low cell line MCF-7, and cytotoxicity was significantly suppressed even at high concentrations. Cytotoxicity studies further revealed that HA-Ns-Dox exhibited significant antiproliferative activity in CD44-high cells while substantially reducing toxicity toward non-target cells. Collectively, these findings demonstrate the potential of combining CD44-targeted delivery with GSH-responsive prodrug activation to improve cancer cell selectivity."

High recurrence rates and enduring symptoms despite current treatments underscore the need for a more thorough understanding of its intricate biology. There is growing evidence that the interaction among oxidative stress (OS), microbiome dysbiosis, and epigenetic dysregulation contributes to immunological activation, hormonal imbalance, and the persistence of ectopic lesions. Important disease mechanisms, such as progesterone resistance, inflammatory signaling, and aberrant cellular proliferation, are influenced by epigenetic changes, which include aberrant DNA methylation, histone modifications, and dysregulated non-coding RNAs. Simultaneously, high levels of reactive oxygen species (ROS) reinforce lesion survival and chronic inflammation by promoting angiogenesis, fibrosis, and tissue damage. Changes in the microbiome also affect immunological responses, oxidative balance, estrogen metabolism, and epigenetic control, indicating the existence of interrelated pathogenic loops. This narrative review presents an integrated mechanistic framework for endometriosis, summarizing the available data that connect these pathways. Furthermore, the growing implications of non-invasive biomarkers and precision medicine techniques highlight the potential for improved diagnosis, disease classification, and targeted treatment approaches."

To overcome these limitations, we developed an all-in-one prodrug nanoplatform based on hyaluronic acid (HA) that synergistically integrates active targeting, pH-responsive charge reversal, and controlled drug release. Doxorubicin (DOX) was covalently conjugated to oxidized HA via a pH-sensitive imine bond, while a charge-reversal polymer (PLL-DMMA) was grafted onto the HA backbone. This design enables CD44-mediated active targeting toward cancer cells. Crucially, the nanoplatform exhibits a smart charge-reversal characteristic: maintaining a negative surface charge (-32.8\u00a0mV) at physiological condition (pH 7.4) for extended circulation, while switching to positive (+16.5\u00a0mV) in the acidic tumor microenvironment (pH 6.5) to enhance cellular uptake. In vitro studies demonstrated significantly improved internalization in CD44-overexpressing MKN-45 cells compared to SNU-216 cells with low CD44 expression. The release profile showed high stability at pH 7.4 (<5% release in 5\u00a0days) and rapid drug release at endo/lysosomal pH (61.6% at pH 5.0). Cytotoxicity assays confirmed enhanced efficacy of the charge-reversed formulation, with lower IC50 values in both cell lines. This multifunctional prodrug nanoplatform represents a promising strategy for precision cancer chemotherapy through synergistic enhancement of tumor targeting and intracellular drug delivery."

In this study, hyaluronic acid (HA) and glycyrrhetinic acid (GA) were separately conjugated to D-alpha tocopherol acid polyethylene glycol succinate (TPGS), which subsequently self-assembled into nanoparticles (HA/GA-NPs). Bletilla striata polysaccharide (BSP) and HA were employed as the microneedle matrix to fabricate soluble microneedles incorporating the nanoparticles (HA/GA-NPs-MNs). This strategy combined the CD44-targeting capability and anti-inflammatory activity of the nanoparticles with the immunomodulatory function and efficient penetration-enhancing ability of the BSP-based microneedles, thereby achieving synergistic therapeutic effects against psoriasis. In vitro studies demonstrated that the CD44-targeting capability of HA/GA-NPs enhanced cellular uptake, reduced intracellular ROS expression, and suppressed the inflammatory proliferation of HaCaT cells. Concurrently, BSP and HA/GA-NPs synergistically promote M2 polarization in RAW264.7 cells while suppressing the production of NO and proinflammatory factors IL-6, TNF-\u03b1, and IL-1\u03b2. Furthermore, HA/GA-NPs-MNs enhanced drug accumulation and skin penetration, enabling efficient delivery into the deeper skin layers. During in vivo studies, the system was observed to significantly enhance immune regulation and demonstrated the strongest efficacy in suppressing psoriatic inflammatory infiltration. The primary therapeutic mechanism of HA/GA-NPs-MNs against psoriasis involved the blockade of STAT3 phosphorylation to inhibit IL-23 signaling and downstream IL-17 release.

Twenty-eight adult female Wistar rats were randomized (n\u2009=\u20097/group) to sham group (G1), untreated endometriosis-group (G2), single-dose DP-MSCs-group (G3) (2\u2009\u00d7\u2009106 cells intraperitoneally on day 28) and double-dose DP-MSCs-group (G4) (2\u2009\u00d7\u2009106 cells on days 28 and 35). Endometriosis was induced by autologous uterine tissue implantation onto the peritoneal wall and allowed to establish for 28\u00a0days; treatment effects were assessed 7\u00a0days after the final DP-MSCs dose. Serum and peritoneal TNF-\u03b1, IL-6, VEGF, and CA-125 were quantified; lesions were evaluated by semi-quantitative histopathology and fibrosis grading and by immunohistochemistry for CA-125, VEGF, type I collagen (Col1), and TNF-\u03b1.

Current treatments often face challenges including limited targeting efficacy and systemic side effects. To develop a novel targeted therapy for RA, this study constructed a functionalized extracellular vesicle (EV) system by engineering ginseng stems and leaves-derived EVs with hyaluronic acid (HA) modification and curcumin (Cur) loading (Cur@EVs-PH). Structurally, the EVs-PH drug-loaded nanoplatform integrates the remarkable anti-inflammatory and antioxidant properties of EVs with the prolonged circulation capacity conferred by PEG. This design further capitalizes on the targeting ability of HA, thereby providing a robust structural foundation for the efficient delivery of therapeutics to disease sites. Our results demonstrated that the designed system achieved enhanced inflammatory targeting through CD44 receptor-mediated accumulation and exhibited potent anti-inflammatory and antioxidant activities. In the collagen-induced arthritis model, Cur@EVs-PH significantly alleviated joint swelling, reduced pathological scores and normalized immune organ indices. Mechanistic studies revealed that the therapeutic effects were mediated through suppression of pro-inflammatory cytokines and promotion of macrophage M2 polarization. This integrated strategy combining natural EVs, targeted modification and active drug loading provides a promising platform for the treatment of RA and other inflammatory diseases."

As a vitreous substitutes, HA-based hydrogels have similar properties to natural vitreous humor. In the field of skin regeneration, HA has the ability to accelerate wound healing and construct complex skin substitutes. For DDS, different forms such as HA-drug conjugate nanoparticles (NPs), HA-surface modified NPs, nanomicelles, and hydrogels can be applied. The preparation methods, delivery mechanisms, in vitro and in vivo evaluations, and advantages of DDS are explained.

Clinical treatments face major challenges, including postoperative recurrence, refractory bone defects, and inadequate targeting of chemotherapeutic drugs. Hyaluronic acid (HA), a natural component of the human extracellular matrix, serves as an ideal material for integrating osteosarcoma therapy and postoperative bone regeneration, attributed to its unique properties including CD44-mediated tumor targeting, tumor microenvironment-responsive degradation, excellent biocompatibility, and functional tunability. This review summarizes recent advances in HA-based materials for osteosarcoma therapy. HA acts as a versatile carrier for chemotherapeutic drugs (e.g. doxorubicin (DOX), cisplatin (CDDP)) and therapeutic nucleic acids, via nanoparticles, liposomes, or hydrogels. These carriers enhance intratumoral drug accumulation, reduce systemic toxicity, evade immune recognition, and facilitate intracellular drug delivery. Incorporating bioactive glass or magnesium-based nanomaterials into HA constructs a multifunctional therapy-regeneration system, which simultaneously inhibits tumor growth and promotes bone regeneration, addressing postoperative bone defects. Furthermore, we analyze key obstacles to clinical translation, such as rapid degradation, insufficient hydrogel mechanical strength, and poor sterilization compatibility, and propose solutions including chemical cross-linking and composite modification. These insights provide valuable guidance for the precise design of HA-based biomaterials and their clinical translation, aligning with the demand for therapy-repair integration in regenerative medicine."

The cavity left after tumor resection represents a valuable opportunity to deliver therapeutics locally via the placement of conformable scaffolds for the immediate chemotherapeutic targeting of GSCs and residual glioblastoma cells. We hypothesized that Surgiflo\u2122, a moldable, FDA-approved gelatin-based hemostatic paste, could serve as a dual-purpose platform that minimizes postoperative bleeding and functions as a conformable, local, and sustained drug-delivery system. We incorporated a pH-sensitive designed hyaluronic acid-doxorubicin polymer-drug conjugate (HA-DOX) into the Surgiflo\u2122 matrix, exploiting HA's selective affinity for CD44 (highly expressed by both GBM and GSCs) and promoting the depletion of GBM and GSCs via immunogenic cell death (ICD)-inducing properties of DOX. In vitro studies of HA-DOX-containing paste confirmed enhanced HA-DOX uptake in GSC-enriched models, improved ICD induction in GBM cells, favorable biocompatibility, and sustained drug release. In vivo evaluations revealed that intracavitary implantation of the HA-DOX-containing paste significantly prolonged the median survival of treated mice compared to the untreated group (37 days vs 25 days, respectively) and modulated the glioblastoma-associated TIME, resulting in a 44% reduction in GSC levels and a significant increase in CD8+ T cell levels (\u2217p\u00a0<\u00a00.5), compared to resected mice.

Although gemcitabine (GEM) is the gold standard for PC, the acquired resistance and severe myelosuppression limit clinical utility. It has been found that abnormal aerobic glycolysis may be responsible for drug resistance in PC. Disulfiram (DSF), a commonly used anti-alcoholic drug, possesses potent anti-tumor activity combined with copper. Nevertheless, poor water solubility and neurotoxicity restrict clinical applications. Therefore, our group modified the structure of DSF and synthesized a novel compound CPD12C15, which exhibited stronger anti-tumor activity and lower neurotoxicity than DSF.

Overcoming these obstacles requires a deep integration of renal physiopathology with advanced drug delivery engineering. This review provides a comprehensive analysis of the mechanisms governing kidney-targeted drug delivery. We first dissect the unique physiological barriers that dictate renal drug disposition, including the size- and charge-selective glomerular filtration barrier (\"the sieve\") and the high-capacity reabsorption machinery of the proximal tubule (e.g., megalin-mediated endocytosis). Subsequently, we elucidate the pathological alterations in the \"fibrotic niche\", highlighting emerging therapeutic targets such as the upregulated CD44 receptor and specific integrins on myofibroblasts. Based on this understanding, we systematically categorize current delivery strategies into two paradigms: (1) Passive Targeting, which exploits physicochemical properties (e.g., 75-100\u00a0nm size range for mesangial sequestration); and (2) Active Targeting, which utilizes ligand-receptor precision to direct carriers to the tubular epithelium (via megalin or transporters) or the fibrotic microenvironment (via hyaluronic acid or RGD [Arg-Gly-Asp]). Finally, we discuss the challenges of clinical translation, including interspecies differences and long-term nanotoxicology, and outline future directions in bio-inspired vectors and stimuli-responsive logic-gated systems. Ultimately, the seamless integration of these modular delivery platforms with patient-specific molecular signatures heralds a new era of precision nephrology, moving beyond systemic management toward site-specific interventions that may fundamentally reverse the progression of renal failure."

Among the key design parameters of HA-based nanocarriers, molecular weight (MW) critically influences biological performance; yet the optimal MW remains controversial. Although higher MW is often assumed to enhance CD44 binding and targeting efficiency, evidence indicates that its effects are multidimensional, context-dependent, and frequently non-linear. This review systematically examines how the MW of HA regulates cellular uptake, active targeting, drug solubilization, release kinetics, biodegradation, immunomodulation, and translational potential. At the cellular level, HA MW modulates multivalent CD44 engagement and receptor clustering, often producing a bell-shaped relationship with internalization efficiency. At the tissue level, MW affects tumor accumulation through competing influences on receptor avidity, nanoparticle size, and systemic clearance. Lower-MW HA generally promotes barrier penetration, cellular uptake, and pro-inflammatory responses, whereas higher-MW HA enhances stability, anti-inflammatory signaling, and circulation time but may reduce uptake due to steric hindrance. Overall, optimal MW selection depends on nanocarrier design, disease context, and dominant biological barriers. This review provides a mechanistic framework to guide rational MW selection in next-generation HA-based nanotherapeutics."

For patients with advanced, unresectable disease, transarterial chemoembolization (TACE) is a recommended first-line locoregional therapy. However, its efficacy is constrained by the inherent limitations of conventional embolic materials-such as non-target embolization, vessel recanalization, and incomplete distal occlusion-and by the low intra-tumoral delivery efficiency of chemotherapeutic agents. Furthermore, the high prevalence of p53 mutations (~\u200930%) in HCC drives tumorigenesis and chemoresistance, creating a critical therapeutic gap, especially within the hypoxic tumor microenvironment. To address these multifaceted challenges, we developed an innovative theranostic platform, CHSA/NAT. This system combines a radiopaque, thermosensitive hydrogel (NAT) for precise, image-guided vascular occlusion with CD44-targeted, glutathione (GSH)-responsive chitosan/hyaluronic acid nanomicelles (CHSA), which enable the smart delivery of arsenic trioxide (ATO)-a potent agent with p53-mutant corrective activity. In vitro, ATO demonstrated superior cytotoxicity over doxorubicin against multiple HCC cells under hypoxia. In a p53-mutant PLC/PRF/5 subcutaneous model, CHSA-ATO achieved a tumor inhibition rate of 84.6%, significantly outperforming free ATO and doxorubicin, and effectively modulated apoptotic proteins (downregulating mutant p53/Bcl-2, upregulating Bax). Crucially, superselective administration of CHSA/NAT enabled successful embolization with clear radiological visualization in rat hepatic and renal arteries, demonstrating its precise image\u2011guided delivery and embolization capability. Most importantly, in an orthotopic rat HCC model, the combined treatment exhibited powerful synergistic efficacy, attaining a remarkable 96% tumor suppression rate and significantly prolonging survival, with a favorable safety profile. This work presents a novel \"embolization\u2011imaging\u2011targeted chemotherapy\" strategy that simultaneously overcomes the key limitations of conventional TACE and ATO delivery, offering a promising and translatable nanoplatform for the effective treatment of advanced HCC."

Non-alcoholic steatohepatitis, the inflammatory form of metabolic dysfunction-associated steatotic liver disease (MASLD, formerly known as non-alcoholic fatty liver disease, NAFLD), serves as a key driver of the HF process. Although previous studies have found that lupeol can act as an FXR-agonist to ameliorate MASLD through the FXR-SHP pathway, its therapeutic potential is severely limited by drawbacks such as poor solubility, low stability, rapid degradation, insufficient targeting specificity, collectively constrain its therapeutic potential. To overcome these limitations, we developed the HA/Lupeol@ZIF-8-a dual-functional nano-delivery system combining CD44-targeting and pH-responsive drug release. It encapsulates the FXR-agonist lupeol in ZIF-8 framework and is surface-modified with hyaluronic acid to allow for active targeting of CD44-highly-expressing aHSCs. In the acidic-fibrotic microenvironment, ZIF-8 undergoes pH-responsive degradation, enabling precise release of both the lupeol and Zn2+. The released Zn2+ further disrupt glycolysis and facilitate the reversion of aHSCs to quiescent state, thereby synergistically enhancing the anti-fibrotic efficacy. The nanoparticles exhibited a uniform size (125.7\u202f\u00b1\u202f0.16\u202fnm), high stability, pH-dependent drug release and strong CD44-binding affinity, collectively improving lupeol's solubility and targeted delivery. Both in vitro and vivo experiments confirmed that HA/Lupeol@ZIF-8 suppresses fibrotic markers through FXR-SHP activation. This study not only elucidates the anti-fibrotic mechanism of Lupeol but also presents an integrated targeted and microenvironment responsive strategy with considerable potential for clinical translation in the treatment of HF."

This review synthesises current molecular evidence to propose a unified mechanistic framework initiated by tissue injury and repair (TIAR), aberrant stem cell activation, or de novo metaplasia, all of which converge to disrupt the endometrial-myometrial interface disruption (EMID). Following this structural breach, a self-perpetuating 'vicious cycle' is triggered, driven by four interconnected axes: (1) Hormonal Dysregulation, characterised by local hyper-estrogenism, progesterone resistance, and a specific paracrine prolactin loop that drives reactive myometrial hypertrophy; (2) Immune-Hemostatic Crosstalk, where activated platelets and M2-polarised macrophages establish a pro-fibrotic niche via TGF-\u03b21 signalling; (3) Hypoxia and Neuroangiogenesis, where HIF-1\u03b1 stabilisation orchestrates metabolic reprogramming (Warburg effect) and the pathological sprouting of sensory nerves, underpinning chronic pain; and (4) Epigenetic Fibrosis, driven by the oestrogen-slug-VEGF axis and HDAC-mediated chromatin remodelling leading to epithelial-mesenchymal transition (EMT). Furthermore, we clarify the genetic distinction between adenomyosis and uterine leiomyomas, highlighting their divergent responses to androgen receptor signalling. By elucidating these molecular targets, we discuss emerging non-hormonal therapeutics-including anti-platelet agents and dopamine agonists-offering mechanism-based strategies for fertility preservation."

Overcoming drug resistance and enhancing tumor-specific drug delivery are key challenges in improving therapeutic outcomes. This study aimed to develop actively targeted cyclodextrin-based nanoparticles co-loaded with gemcitabine (GEM) and paclitaxel (PCX) to improve efficacy against pancreatic cancer, particularly in drug-resistant phenotypes. Hyaluronic acid (HA) was used to functionalize the nanoparticles for CD44-mediated active targeting. Comprehensive physicochemical characterization including particle size, zeta potential, drug loading, release profile, and stability was conducted. In vitro studies covered both 2D monolayer and 3D spheroid models of pancreatic cancer, including drug-resistant Panc-1 cells. Apoptosis induction and cholesterol depletion were assessed for mechanistic evaluation. In vivo studies in tumor-bearing mice were performed for efficacy, biodistribution, and systemic safety. All nanoparticle formulations exhibited sub-200 nm diameters, high drug loading efficiencies (>50 %), and sustained release profiles. HA-functionalized nanoparticles demonstrated enhanced cellular uptake, significant cytotoxicity, and apoptosis in both drug-sensitive and resistant cells. In vivo, CD44 targeted dual-drug nanoparticles significantly inhibited tumor growth, showed enhanced intratumoral accumulation, and exhibited no systemic toxicity. These findings suggest that HA-functionalized amphiphilic cyclodextrin nanoparticles co-loaded with GEM and PCX represent a promising strategy to overcome chemoresistance and improve therapeutic efficacy in pancreatic cancer."

Paclitaxel (PTX), a first-line chemotherapeutic agent widely used in breast cancer, is widely used due to its potent mechanism of action against rapidly dividing cancer cells. However, its clinical application is significantly hindered by poor solubility, systemic toxicity, and associated adverse effects. Encapsulating PTX in polymeric nanoparticles presents a promising strategy to overcome these limitations by extending drug release, enhancing drug's bioavailability, and enabling active targeting. This review uniquely focuses on recent advances in surface-functionalized polymeric nanoparticles specifically engineered for targeted delivery of PTX in breast cancer therapy and consolidates their translational relevance and next-generation design considerations. Unlike general reviews on polymeric nanocarriers, this article specifically focuses on ligand-functionalized polymeric nanoparticles designed for active targeting of breast cancer cells, integrating biological rationale, receptor specificity, and translational relevance. Surface-engineered polymeric nanoparticles functionalized with ligands such as folic acid, hyaluronic acid, aptamers, and peptides can specifically target overexpressed receptors on cancer cells, including CD44, HER2, and folate receptors. These ligand-receptor interactions facilitate receptor-mediated endocytosis, enhancing intracellular drug delivery while minimizing systemic toxicity. The review highlights key design considerations, including ligand density, nanoparticle architecture, and multifunctionality of next-generation PTX nanocarriers. The development of PTX-loaded polymeric nanoparticles with surface modifications represents a significant advancement in precision drug delivery for breast cancer, addressing key treatment challenges and paving the way for clinical translation."

Owing to its anti-inflammatory properties, biocompatibility and ability to contribute to ECM remodeling, HA is considered a promising therapeutic candidate for neurodegenerative diseases. This review summarizes the application of HA to treat Alzheimer's disease (AD) and Parkinson's disease (PD) and outlines the current understanding of the mechanism of action and strategies for HA-based biomaterial modification. For AD, HA is involved in several mechanisms including stabilizing the perineuronal net, reducing the toxic effects of A\u03b2 and hyperphosphorylated tau, and modulating neuroinflammation through CD44/RHAMM signaling pathways. HA-based nanoparticles and hydrogels enhance drug delivery across the blood-brain barrier, facilitate A\u03b2 clearance, and enable sustained, controlled release of therapeutic agents. In PD, HA regulates autophagic flux, inhibits \u03b1-synuclein propagation, and remodels the ECM to protect dopaminergic neurons. Modifications such as HA hydrogels with neurotrophic factors improve cell transplantation outcomes, while conjugates enhance mitochondrial targeting and dopamine delivery. While numerous preclinical studies have shown promise, significant challenges remain, including the high variability of HA formulations, limited blood-brain barrier penetration efficiency, and a paucity of well-designed clinical trials to validate preliminary findings. Future directions include standardizing laboratory protocols, developing hybrid systems integrating vascular endothelial growth factor and gene therapy, and adopting a patient-specific approach that leverages HA's multi-targeted effects on the nervous system."

To address these challenges, we engineered a targeted co-delivery platform by systematically comparing two representative, probiotic-derived extracellular vesicle carriers: outer membrane vesicles (OMVs) from Escherichia coli Nissle 1917 and extracellular vesicles (EVs) from Lactobacillus plantarum. Encapsulation efficiency (EE) of Cur was 41.6% for OMVs and 35.9% for EVs, whereas EE of Ant was 25.4% and 24.6%, respectively. Both vesicle types were further synergistically functionalized with specifically acylated epigallocatechin palmitate (EGCp) and octenyl succinic anhydride-grafted hyaluronic acid (OSA-HA). The incorporation efficiency of EGCp was 27.2% for OMVs and 37.3% for EVs. The self-assembly process yielded composite nanovesicles with a reduced particle size (OMVs: from 165.6\u00a0nm to 143.2\u00a0nm; EVs: from 156.8\u00a0nm to 120.8\u00a0nm) and a more negatively charged surface (from -20.8\u00a0mV to -37.5\u00a0mV for OMVs; from -18.3\u00a0mV to -35.3\u00a0mV for EVs) compared to their native counterparts, indicating improved colloidal properties. In addition, both engineered nanovesicles effectively protected the encapsulated bioactives, significantly enhancing their stability against simulated gastrointestinal digestion and oxidative stress. For example, the retention of Cur under oxidative conditions increased from 24.2% in unmodified OMVs to 69.1% in the optimized formulation within 2\u00a0h. Cellular uptake assays confirmed the OSA-HA coating achieved targeted delivery to inflammatory macrophages, with OSA-HA-modified OMVs exhibiting higher cellular internalization (75.4% at 12\u00a0h) than similarly modified EVs (61.8% at 12\u00a0h). While both types of functionalized nanovesicles enhanced intracellular antioxidant activity to a similar extent, the OMV-based system demonstrated superior suppression of pro-inflammatory mediators (NO, TNF-\u03b1, and IL-6) in mitigating lipopolysaccharide (LPS)-induced cell damage. This comparative study establishes a biocompatible probiotic-based colloidal platform, demonstrating the potential of two selected engineered probiotic vesicles and functionalized polysaccharides for the encapsulation and targeted cellular delivery of sensitive bioactive compounds."

However, advances in optics and fluidics have enabled cytometers primarily designed for cells to detect viruses and extracellular vesicles (EVs) through light scatter alone. In 2024, the CytoFLEX nano was released, marketed for the detection of particles as small as 40\u00a0nm; however, its performance has yet to be compared to a conventional instrument for FV. FV was utilized to evaluate performance of the CytoFLEX nano and a conventional flow cytometer (CytoFLEX S). Instrument scatter sensitivity was assessed using NIST beads (40-400\u00a0nm), and virus stocks [human immunodeficiency virus (HIV), human coronaviruses (HCoV)-229E and HCoV-OC43]. For fluorescence analysis, HIV virions were stained with PE- and BV421-conjugated antibodies targeting virion incorporated proteins (CD38, CD44), individually and in combination. Finally, HIV stocks were labeled with antibodies against the envelope (Env) glycoprotein and tetraspanins (CD9, CD81) to assess EVs within virus preparations. Compared to the CytoFLEX S, the CytoFLEX nano exhibited substantially greater scatter sensitivity, reflected by up to 50-fold higher signal-to-noise ratio across NIST-traceable beads and virus samples. This enabled clearer resolution of smaller populations, including bead populations\u2009<\u200970\u00a0nm that were undetectable on the CytoFLEX S, as well as improved resolution across all viruses. While both instruments reliably detected stained proteins on HIV virions, the CytoFLEX nano revealed a distinct population of tetraspanin-positive EVs within HIV stocks that was undetected on the CytoFLEX S. Using GFP-tagged HIV, we identified Env+ particles lacking GFP, indicating the presence of Env on EVs. The CytoFLEX nano exhibited markedly improved scatter sensitivity compared to the CytoFLEX S, improving detection of viruses and enabling detection of EV populations that were undetectable on the conventional instrument. While both platforms performed similarly for surface protein labeling, additional consideration of spectral overlap was needed with the CytoFLEX nano in multicolor experiments. These findings highlight that the complementary strengths of each platform can be utilized to more comprehensively characterize virus and EV populations, providing new opportunities to investigate nanoparticle heterogeneity."

Given current treatment limitations, novel strategies like mesenchymal stem cells (MSC) derived conditioned media (CM) are explored due to their rich secretome. To investigate the effects of CM from healthy menstrual blood-derived MSCs (MenSCs-CM) and human adipose tissue-derived MSCs (ADSCs-CM) on apoptosis and migration in endometriotic MenSCs.

Impaired endometrial receptivity, mediated by altered transcription factors, adhesion molecules, and extracellular matrix components, has been proposed as a contributing mechanism. This study aimed to evaluate compartment-specific immunohistochemical expression patterns of HOXA-10, HOXA-11, CD44, \u03b21 integrin, ECM-1, and focal adhesion kinase (FAK) in women with endometriosis-related implantation failure. METHODS: This retrospective case\u2013control study was conducted at the IVF Unit of Gazi University Faculty of Medicine. The study group consisted of 34 infertile women with surgically confirmed endometriosis and recurrent IVF failure, subdivided into pre-receptive and receptive phases based on histological dating, while fertile women without infertility or endometriosis served as controls. Endometrial biopsies were obtained during the implantation window. Immunohistochemical expression was evaluated using semi-quantitative compartment-specific scoring, with ImageJ-based analysis used as supportive. Appropriate non-parametric statistical analyses were applied, and p\u2009<\u20090.05 was considered statistically significant. RESULTS: No statistically significant intergroup differences were observed for stromal HOXA-10 or HOXA-11 expression between control, pre-receptive, and receptive groups. Glandular CD44 positivity was significantly increased in the receptive group compared with controls, while no significant difference was detected between pre-receptive and receptive phases after multiple comparison correction. \u03b21 integrin expression did not demonstrate consistent phase-specific differences. In contrast, strong glandular ECM-1 expression was significantly reduced in both pre-receptive and receptive groups compared with controls, whereas stromal ECM-1 expression remained unchanged. Stromal FAK expression was significantly increased in both pre-receptive and receptive groups relative to controls, with no significant difference between these phases. CONCLUSION: Endometriosis-related implantation failure is associated with distinct, compartment-specific alterations in endometrial receptivity markers that appear largely independent of physiological implantation timing. Reduced glandular ECM-1 expression and persistent stromal FAK accumulation suggest disease-specific epithelial\u2013stromal dysregulation rather than delayed or shifted receptivity. Altered glandular CD44 expression in the receptive phase likely reflects endometriosis-associated epithelial adhesion changes rather than a phase-specific marker of functional receptivity. These findings highlight the importance of compartment-focused evaluation of endometrial receptivity in endometriosis-related infertility. TRIAL REGISTRATION: This study was retrospectively conducted and was not registered in a clinical trial registry."

Growing interest has recently been drawn towards glycan structures on EVs. Hyaluronic acid (HA) is a negatively charged glycosaminoglycan that can decorate the surface of EVs from different origins. HA is a ligand for adhesion receptor CD44, which is overexpressed in various cancers and inflammatory diseases. Although HA has been utilised as a surface decoration to improve CD44-mediated targeting of synthetic nanoparticles and EVs, the role of CD44 in the uptake of EVs is not well known. To assess the importance of CD44 in the interactions and endocytosis of HA-decorated EVs, uptake of HA-decorated and nondecorated EVs into CD44-expressing and -deficient cells was investigated using microscopic methods. The uptake of HA-decorated EVs was significantly increased into cells that expressed CD44, but no differences in endocytosis mechanisms were found. Additionally, the formation of plasma-derived protein corona in HA-decorated and nondecorated EVs was investigated using multi-parametric surface plasmon resonance and mass spectrometry. HA-decoration was found to cause a formation of thicker corona and enrichment of plasma-derived protein corona components. These findings highlight the role of HA in enhancing CD44-mediated EV targeting and modulating the composition of protein corona."

However, these formulations suffer from limited scalability, high-cost reagents, and long optimization timelines.

We evaluate the effect of bEVs on the vaginal microenvironment, and observe no negative impact on vaginal epithelial cells, endocervical cells, or vaginal bacteria in vitro. Additionally, we observe the retention of bEVs in the murine female reproductive tract for more than six hours.

Here, we present a lyophilized hyaluronic acid (HA)-coated formulation of EVs derived from human adipose stem cells, engineered to enhance both therapeutic efficacy and long-term preservation. This formulation leverages the natural affinity between HA and the CD44 proteins expressed on the EV membranes, forming stable HA-EV complexes that remain intact following lyophilization and rehydration. These HA-EVs exhibited superior targeting of CD44-expressing cells, including pro-inflammatory macrophages and senescent dermal fibroblasts, thereby effectively suppressing inflammatory responses and restoring fibroblast function in a wound-healing mouse model. Notably, HA-EVs significantly accelerate wound healing by promoting collagen synthesis within the dermal layer, outperforming bare EVs. Furthermore, HA served as an effective cryoprotectant, preserving the physicochemical and biological integrity of EVs for at least six months at 4 \u2103. Taken together, our results establish lyophilized HA-EVs as a robust and clinically translatable platform that integrates cell-specific targeting with long-term storage stability for regenerative medicine applications."

It is characterised by ectopic (ECT) growth of endometrial-like tissue mainly in the pelvic cavity. Small extracellular vesicles (sEVs) mediate cellular interactions, but their function remains poorly understood in the pathogenesis of EM. 3D endometrial epithelial organoids (EEOs) from ECT lesions and eutopic (EUT) endometrium from EM patients and controls were established to investigate sEVs. Multiplex bead-based flow cytometry revealed CD133/1 and EpCAM as dominant markers on EEO-sEVs, with ECT EEO-sEVs showing upregulation of CD44, CD29 and downregulation of EpCAM compared to EUT EEO-sEVs. Peritoneal fluid (PF)-sEVs displayed high and correlated CD133/1 and EpCAM expression, indicating a major contribution from endometrial epithelial (EE) cells, alongside sEVs of lymphocyte and endothelial origin. Functionally, both ECT EEO-sEVs and PF-sEVs from EM patients significantly suppressed macrophage phagocytosis, as assessed by pH-sensitive fluorescent bioparticles. The effect was reversed by CD47 blockade. The coexpression of CD47 with CD133/1 and EpCAM on PF-sEVs indicates the involvement of EE cell-derived sEVs in CD47/SIRP-\u03b1 mediated suppression.

Emerging evidence suggests endometrial stem cells (EnSCs) contribution in disease pathogenesis, including mesenchymal stem cells (E-MSCs), epithelial progenitor cells (EPCs), and side population cells (ESPs). These stem/progenitor cells are involved in proliferation, migration, and angiogenesis, contributing to endometriosis genesis and persistence. Targeting EnSCs and their regulatory pathways present a promising therapeutic strategy to improve unmet needs in endometriosis. This scoping review was based on a systematic literature search conducted in PubMed, EMBASE, and Web of Science considering studies published after 2000. Inclusion criteria focused on original research articles exploring the role and targeting of EnSCs in endometriosis, following PRISMA-ScR guidelines. Data were synthesized through narrative and descriptive methods. The review structures key pathways and therapeutic agents targeting EnSCs in endometriosis. Notch1, PI3K/Akt, Wnt/\u03b2-catenin, and JAK/STAT signalling are pathways that regulate proliferation, migration and survival of EnSCs in endometriosis. Agents such as metformin, lovastatin, sorafenib, quinagolide, and \u03b3-secretase inhibitors demonstrated potential to modulate stemness, leading to a decrease in inflammation, migration and apoptosis. Anti-angiogenic agents showed efficacy in reducing lesion size In vivo, targeting E-MSCs. Exosomes emerge as a cell-free approach, derived from menstrual stem cells (MenSCs) or ginger-based nanoparticles and exhibited properties essential for endometriosis treatment, directed to ectopic stem cells. EnSCs sustain aberrant cellular behaviours in endometriosis. Targeting EnSCs and their related pathways may be an innovative, individualized, and disease-modifying strategy. Pharmacological modulation, gene therapy and exosome are strategies for stem cell inhibition in endometriosis, being a promising avenue for future research leading to application in clinical practice."

However, despite growing interest, the development of ELNs for nucleic acid delivery remains a formidable challenge, compounded by diverse production methods and a lack of systematic approaches to optimize their formulation and performance. This study employed a Box-Behnken design and two fabrication methods: freeze-thaw and sonication, to optimize the formulation of ELNs derived from exosomes of five distinct cancer cells. Formulation criteria focused on maximizing the fusion efficiency while minimizing particle size. The impact of the fusion method on cellular association and gene silencing of promising therapeutic targets, CD24, CD44, and CD47, was evaluated. The optimized formulations were subsequently assessed for therapeutic efficacy in 4T1 and B16F10 tumor models. Through careful manipulation of formulation variables, we obtained optimal ELNs with fusion efficiencies exceeding 50% and particle sizes under 170 nm while preserving exosomal markers CD9, CD63, and CD81. Cellular association studies revealed that ELNs specifically targeted their parental cell line, achieving \u223c2.5-fold higher siRNA association compared to LNPs. Furthermore, the optimized ELNs facilitated the delivery of therapeutic siRNAs, resulting in robust gene silencing and consequently improved the in vitro macrophage-mediated phagocytosis of treated cancer cells. In vivo studies using 4T1 and B16F10 tumor models highlighted the enhanced therapeutic potential of the optimized ELNs, as evidenced by significant tumor targeting and growth inhibition. These findings underscore the importance of systematic formulation and method optimization in advancing ELNs as effective nucleic acid delivery platforms for cancer therapy."

Conventional hormonal therapies suppress systemic oestrogen, but do not fully address local oxidative and inflammatory signalling. This review provides a mechanistic synthesis of recent molecular evidence. This evidence is on four FDA-recognized (Food and Drug Administration) medicinal plants. These are Curcuma longa, Zingiber officinale, Glycyrrhiza glabra, and Silybum marianum. The review highlights their capacity to modulate key intracellular pathways. These pathways are implicated in endometriosis. The review covers the integration of phytochemical-specific actions within NF-\u03baB- (nuclear factor kappa-light-chain-enhancer of activated B cells), COX-2-(Cyclooxygenase-2), PI3K/Akt-(PI3K/Akt signaling pathway), Nrf2/ARE-(Nuclear factor erythroid 2-related factor 2) and ER\u03b2-(Estrogen receptor beta) mediated networks, which jointly regulate cytokine secretion, apoptosis, angiogenesis and redox balance in endometrial lesions. Curcumin downregulates COX-2 and aromatase while activating Nrf2 signalling, shogaol from ginger suppresses prostaglandin synthesis and induces caspase-dependent apoptosis, isoliquiritigenin from liquorice inhibits HMGB1-TLR4-NF-\u03baB (High Mobility Group Box 1, Toll-like receptor 4) activation, and silymarin from milk thistle reduces IL-6 (Interleukin-6) and miR-155 (microRNA-155) expression while enhancing antioxidant capacity. Together, these phytochemicals demonstrate pharmacodynamic complementarity with hormonal agents by targeting local inflammatory and oxidative circuits rather than systemic endocrine axes. This mechanistic framework supports the rational integration of phytotherapy into endometriosis management and identifies redox-inflammatory signalling nodes as future translational targets."

Recent advances in cancer biology have identified liver cancer stem cells (LCSCs) as a subpopulation within tumors that possess self-renewal capacity, tumorigenic potential, and resistance to conventional therapies. These cells are characterized by distinct surface markers, such as CD133, EpCAM, CD44, CD90, and ALDH1, and aberrant activation of signaling pathways, including the Wnt/\u03b2-catenin, Notch, Hedgehog, and TGF-\u03b2 pathways. Emerging evidence suggests that LCSCs not only contribute to tumor initiation and progression but also serve as novel diagnostic biomarkers for early detection, prognosis stratification, and therapeutic monitoring in HCC. Circulating LCSC-derived extracellular vesicles and transcriptomic signatures offer promising avenues for noninvasive liquid biopsy approaches. This review synthesizes current findings on the molecular characterization of LCSCs, their clinical relevance, and the potential integration of LCSC biomarkers into precision oncology workflows. Targeting LCSCs may increase diagnostic accuracy and pave the way for more effective, stem cell-directed therapies in liver cancer management."

Identifying new biomarkers for early cancer detection could improve treatment outcomes. Tumor-derived cells release extracellular vesicles (EVs) carrying tumor-specific molecular signatures, which can help distinguish patients with cancer even in early stages. The aim of this study was to assess the potential of EVs as biomarkers to enhance cancer detection in patients with PNS. This observational and multicenter study included 27 patients with tumor-associated PNS, 26 with suspected PNS without a tumor, 35 with cancer, and 32 healthy controls. Subsequently, among the patients with PNS, individuals were subclassified according to the PNS-Care Score as definite, probable, possible, and non-PNS. Total EVs were isolated from blood by precipitation and from B cells, T cells, and neurons by immunoisolation. To identify a biomarker for diagnostic refinement and clinical stratification, EV levels, size, and protein content were compared across study groups. To find a tumor biomarker in intermediate-risk cases, the possible association between EV protein content and cancer detection in intermediate-risk syndromes was analyzed. Patients with tumor-associated PNS showed significantly higher circulating EV levels compared with those with suspected PNS without evidence of a tumor (p = 0.028). Moreover, total EV levels, along with B cell-derived EVs, effectively differentiated patients with definite PNS from those with probable (p = 0.05) and possible (p = 0.006) PNS. A cutoff value of 2.10 \u00d7 1010 particles/mL EVs was identified, above which diagnosis of PNS was definite, with 86% sensitivity and 81% specificity. Proteomic analysis identified specific proteins, including ACADM, HPT, ACTBL, and CCAR2, as markers of definite PNS, differentiating such patients from those with probable and possible PNS, contributing to diagnostic refinement for clinical stratification. It is important to note that increased levels of EVs and CD44 distinguished intermediate-risk cases with tumors from those without. EVs may act as tumor biomarkers in patients with PNS, even in intermediate-risk cases. This study provides Class IV evidence that higher circulating blood levels of EVs can distinguish between tumor-associated PNS from suspected PNS without tumor."

In this study, we integrated the GSE6364 dataset from the GEO database to identify differentially expressed genes, and applied weighted gene co-expression network analysis (WGCNA) to pinpoint gene modules highly associated with EMs. Cross-referencing with macrophage polarization-related genes, we identified 31 key genes. Machine learning algorithms (LASSO, SVM-RFE, and Random Forest) further narrowed down five core targets: CD44, CLU, FOXO1, MET, and SPP1. Single-cell RNA sequencing revealed that SPP1 is predominantly expressed in M2-like macrophages. Functional assays demonstrated that overexpression of SPP1 promotes macrophage polarization toward the M2 phenotype and significantly enhances the proliferation and migration of human endometrial stromal cells (ihESCs). Mechanistically, SPP1+ M2-like macrophages facilitate lesion growth and invasion via activation of the FAK/PI3K/AKT signaling pathway. Histological and immunofluorescence analyses further confirmed the expression and spatial distribution of these core genes in EMs lesions. Taken together, SPP1 acts as a key regulator in M2 macrophages, playing a crucial role in immune modulation and disease progression in EMs, highlighting its potential as a diagnostic biomarker and therapeutic target."

This review highlights recent breakthroughs in biomaterial-assisted delivery of gene therapy tools, such as small\u00a0interfering\u00a0RNA (siRNA), messenger RNA (mRNA), and clustered regularly interspaced short palindromic repeats-CRISPR-associated 9 (CRISPR-Cas9).

The proposed work aims to develop a nanosystem based on gold nanoparticles (AuNPs) to actively target human endometriosis CD44(+) cells and significantly reduce their viability by photothermal therapy (PTT). AuNPs stabilized by lipoic acid-Poly(ethylene glycol)-Maleimide (LA-PEG-Mal) (Au@P) were decorated with antiCD44 antibodies (Au@P_AbCD44) through maleimide chemistry. The physicochemical and biochemical approaches revealed the presence of the antibody on Au@P_AbCD44. The in vitro studies were conducted against overexpressing CD44 cells (12Z), low-expressing CD44 cells (HESC), and the normal fibroblast cell line (NIH-3T3). Following the internalization through the clathrin-mediated endocytosis, the PTT of the cell-internalized Au@P_AbCD44 was investigated using two distinct laser types, due to the differing Au@P's LSPR properties. Au@P_AbCD44 exhibited significant PTT efficacy against 12Z cells; however, GNS@P_AbCD44 required lower energy input compared to GNP@P_AbCD44. This enhanced performance is attributed to the LSPR-mediated photothermal conversion efficiency of GNS over GNPs.In both cases, the apoptotic pathway was selected by dying cells over necrotic cells. The results revealed a better photothermal ability of GNS@P_AbCD44 compared to GNP@P_AbCD44. Our findings highlight the clinical potential of gold nanostars as advanced photosensitizers for targeted photothermal therapy, offering a promising strategy for more effective and less invasive treatment of endometriosis."

Immunohistochemistry (IHC) serves as a vital technique for elucidating the molecular and cellular differences between ectopic endometriotic tissues and eutopic endometrium. IHC reveals significant variations in the expression of inflammatory markers, adhesion molecules, and cell cycle regulators. This literature review compiles findings from various studies that assess the role of key proteins, such as leukemia inhibitory factor (LIF), cyclooxygenase-2 (COX-2), and b-cell lymphoma 2 (BCL-2), across different menstrual phases and lesion types. Notably, elevated LIF levels and increased mast cell activity in ectopic tissues underscore the inflammatory landscape of endometriosis. Additionally, altered expression of adhesion molecules like integrins and cluster of differentiation 44 (CD44) suggests modified cellular interactions, while apoptotic markers reveal a survival advantage for ectopic cells. These insights enhance our understanding of endometriosis pathophysiology."

"abstract_text": "ID: 40567500\nTitle: Intercellular communication between extracellular vesicles from conditioned macrophages and breast cancer cells drives endocrine therapy resistance.\nAbstract: Breast cancer is a leading cause of cancer-related mortality among women, with nearly 70% of cases being estrogen receptor-positive (ER+). While endocrine therapies, such as tamoxifen, have significantly improved patient outcomes, resistance-whether intrinsic or acquired-remains a major clinical challenge that limits treatment efficacy. Emerging evidence suggests that endocrine resistance is often driven by the presence and expansion of cancer stem cells (CSCs), which contribute to recurrence, metastasis, and therapeutic failure. The tumor microenvironment (TME), including immune cells like macrophages, soluble factors, and extracellular vesicles (EVs), plays a crucial role in promoting tumor progression and therapy resistance. EVs are small lipid bilayer-bound particles that facilitate intercellular communication by transferring bioactive cargo capable of reprogramming recipient cells. To investigate the role of macrophage-derived EVs in endocrine resistance, we isolated EVs from TNF-\u03b1-conditioned macrophages (TNF EVs) and treated MCF-7 ER+ breast cancer cells with these vesicles. We assessed changes in proliferation, migration, epithelial-mesenchymal transition (EMT), CSC-like properties, and tamoxifen resistance. Additionally, we evaluated whether tumor-derived EVs modulate macrophage polarization by analyzing the expression of PD-1 and other immunomodulatory markers. TNF EV-treated MCF-7 cells showed significantly increased proliferation, enhanced migratory behavior, and morphological changes associated with EMT. Importantly, treated cells developed a stem-like phenotype, characterized by a larger CD44High/CD24Low subpopulation and improved spheroid-forming ability. These features correlated with sustained proliferation even in the presence of tamoxifen, supporting the development of endocrine resistance. Furthermore, EVs derived from tumor cells triggered macrophage polarization toward a tumor-associated macrophage (TAM) profile, with increased PD-1 expression, indicating a role in immune suppression and tumor immune evasion. These findings emphasize the dual role of TNF-\u03b1-conditioned macrophage-derived EVs in driving both endocrine resistance and immune modulation in ER+ breast cancer. By promoting stemness, EMT, and tamoxifen resistance, as well as inducing immunosuppressive macrophage polarization, these EVs emerge as key contributors to tumor progression. Our study highlights the therapeutic potential of targeting EV-mediated communication to overcome endocrine resistance and enhance clinical outcomes for ER+ breast cancer patients. This work establishes a critical framework for future studies aimed at harnessing EVs as therapeutic targets or biomarkers in breast cancer management."

A targeted drug delivery system (HLC) was constructed using hyaluronic acid (HA) nanomicelles co-loaded with lactate oxidase (LOX) and copper-doped carbon dots (CuCDs). Combined with \u03b1-PD-L1, a synergistic antitumor strategy integrating lactate metabolic regulation, cuproptosis, and immune activation was established. HLC achieves targeted accumulation through specific binding between HA and CD44 receptors on tumor cells. It directionally releases LOX and CuCDs in the acidic TME via pH-responsive properties. LOX efficiently clears lactate and elevates pH, blocking the HIF-1\u03b1/PD-L1 pathway to reverse immunosuppression. It also generates H2O2 in situ to provide substrates for Cu-mediated Fenton-like reactions, enhancing cuproptosis. In vitro experiments confirm that HLC promotes dendritic cell maturation and drives M2-type macrophage polarization toward the M1 phenotype. In vivo studies using CT26 tumor-bearing mouse models show that HLC combined with 808\u202fnm laser and \u03b1-PD-L1 significantly inhibits primary and distant tumor growth. It remodels the antitumor immune microenvironment with favorable biosafety.

Kidney diseases represent a major global health burden, often progressing to chronic complications due to the limited efficacy and poor selectivity of conventional therapies, which are frequently associated with systemic toxicity. Accordingly, the development of targeted drug delivery systems is essential to improve therapeutic outcomes. In this study, advanced quatsomes were developed as a kidney-targeted nanosystem to enhance the delivery of curcumin, a natural polyphenolic compound with potent antioxidant and nephroprotective properties. The system was composed of di-dodecyl-dimethyl-ammonium bromide (DDAB), cholesterol, limonene, hyaluronic acid (HA) and surfactants, and was fabricated using the ethanol injection method. A 23 factorial design was employed to optimize formulation variables, including DDAB:cholesterol ratio, limonene:drug ratio, and surfactant concentration. The optimized formulation (desirability = 0.950) exhibited high entrapment efficiency (87.80%), nanosized vesicles (120.55\u00a0nm), and a positive surface charge (+38.30\u00a0mV). Transmission electron microscopy confirmed spherical morphology, while in-vitro release studies demonstrated a biphasic profile. The formulation also showed good physicochemical stability and enhanced antioxidant activity. Mechanistically, passive targeting via nanoscale size and cationic charge facilitated interaction with the glomerular filtration barrier and mesangial uptake, while limonene improved vesicle deformability. HA functionalization further enabled CD44-mediated active targeting. In vivo, the optimized system significantly reduced serum creatinine and blood urea nitrogen levels in a cisplatin-induced nephrotoxicity model, with histological evidence of renal protection. Overall, the developed quatsomes demonstrate promising potential as an efficient renal-targeted nanocarrier."

Doxorubicin (DOX) was covalently conjugated to oxidized HA via a pH-sensitive imine bond, while a charge-reversal polymer (PLL-DMMA) was grafted onto the HA backbone. This design enables CD44-mediated active targeting toward cancer cells. Crucially, the nanoplatform exhibits a smart charge-reversal characteristic: maintaining a negative surface charge (-32.8\u00a0mV) at physiological condition (pH 7.4) for extended circulation, while switching to positive (+16.5\u00a0mV) in the acidic tumor microenvironment (pH 6.5) to enhance cellular uptake. In vitro studies demonstrated significantly improved internalization in CD44-overexpressing MKN-45 cells compared to SNU-216 cells with low CD44 expression.

Due to its biocompatibility, biodegradability, non-toxicity and cluster of differentiation-44 (CD44) receptor-mediated targeting, it is widely used as a medical material in the fields of tissue engineering, regenerative medicine, and drug delivery systems (DDS). Herein, the latest research on HA-based medical materials over the past 5\u00a0years is systematically reviewed, focusing on the frontier advances on the utilization of HA and its derivatives in cartilage/skin regeneration, vitreous substitutes, and DDS. HA-based hydrogels can be used for articular cartilage regeneration by promoting the proliferation and differentiation of chondrocytes and the formation of ECM. As a vitreous substitutes, HA-based hydrogels have similar properties to natural vitreous humor. In the field of skin regeneration, HA has the ability to accelerate wound healing and construct complex skin substitutes. For DDS, different forms such as HA-drug conjugate nanoparticles (NPs), HA-surface modified NPs, nanomicelles, and hydrogels can be applied. The preparation methods, delivery mechanisms, in vitro and in vivo evaluations, and advantages of DDS are explained.

The resulting nanoparticles exhibited a uniform spherical morphology with an average diameter of approximately 145 nm and demonstrated dual responsiveness to elevated GSH and acidic pH conditions characteristic of the tumor microenvironments. In vitro and in vivo antitumor studies revealed that the co-delivery system significantly enhanced cytotoxicity and apoptosis through synergistic PTX/PIP activity compared with monotherapy. In addition, HA modification markedly improved cellular uptake and tumor accumulation, leading to effective tumor growth inhibition in vivo with reduced systemic toxicity.

Overcoming these obstacles requires a deep integration of renal physiopathology with advanced drug delivery engineering. This review provides a comprehensive analysis of the mechanisms governing kidney-targeted drug delivery. We first dissect the unique physiological barriers that dictate renal drug disposition, including the size- and charge-selective glomerular filtration barrier (\"the sieve\") and the high-capacity reabsorption machinery of the proximal tubule (e.g., megalin-mediated endocytosis). Subsequently, we elucidate the pathological alterations in the \"fibrotic niche\", highlighting emerging therapeutic targets such as the upregulated CD44 receptor and specific integrins on myofibroblasts. Based on this understanding, we systematically categorize current delivery strategies into two paradigms: (1) Passive Targeting, which exploits physicochemical properties (e.g., 75-100\u00a0nm size range for mesangial sequestration); and (2) Active Targeting, which utilizes ligand-receptor precision to direct carriers to the tubular epithelium (via megalin or transporters) or the fibrotic microenvironment (via hyaluronic acid or RGD [Arg-Gly-Asp]). Finally, we discuss the challenges of clinical translation, including interspecies differences and long-term nanotoxicology, and outline future directions in bio-inspired vectors and stimuli-responsive logic-gated systems. Ultimately, the seamless integration of these modular delivery platforms with patient-specific molecular signatures heralds a new era of precision nephrology, moving beyond systemic management toward site-specific interventions that may fundamentally reverse the progression of renal failure."

Non-alcoholic steatohepatitis, the inflammatory form of metabolic dysfunction-associated steatotic liver disease (MASLD, formerly known as non-alcoholic fatty liver disease, NAFLD), serves as a key driver of the HF process. Although previous studies have found that lupeol can act as an FXR-agonist to ameliorate MASLD through the FXR-SHP pathway, its therapeutic potential is severely limited by drawbacks such as poor solubility, low stability, rapid degradation, insufficient targeting specificity, collectively constrain its therapeutic potential. To overcome these limitations, we developed the HA/Lupeol@ZIF-8-a dual-functional nano-delivery system combining CD44-targeting and pH-responsive drug release. It encapsulates the FXR-agonist lupeol in ZIF-8 framework and is surface-modified with hyaluronic acid to allow for active targeting of CD44-highly-expressing aHSCs. In the acidic-fibrotic microenvironment, ZIF-8 undergoes pH-responsive degradation, enabling precise release of both the lupeol and Zn2+. The released Zn2+ further disrupt glycolysis and facilitate the reversion of aHSCs to quiescent state, thereby synergistically enhancing the anti-fibrotic efficacy. The nanoparticles exhibited a uniform size (125.7\u202f\u00b1\u202f0.16\u202fnm), high stability, pH-dependent drug release and strong CD44-binding affinity, collectively improving lupeol's solubility and targeted delivery. Both in vitro and vivo experiments confirmed that HA/Lupeol@ZIF-8 suppresses fibrotic markers through FXR-SHP activation. This study not only elucidates the anti-fibrotic mechanism of Lupeol but also presents an integrated targeted and microenvironment responsive strategy with considerable potential for clinical translation in the treatment of HF."

Within the tumor microenvironment, the interaction between hyaluronic acid (HA) and cluster of differentiation 44 (CD44) is linked to tumor progression and therapeutic failure. Accordingly, targeting the HA-CD44 signaling axis represents a promising strategy to overcome resistance. This review highlights potential approaches, including inhibition of HA synthesis, enzymatic HA degradation, CD44 blockade, and HA-based nanocarriers for selective drug delivery, alone or combined with existing therapies. Leveraging HA-CD44 biology may help refine profiling and support the development of more personalized treatments, ultimately enhancing outcomes for HCC patients."

Overcoming drug resistance and enhancing tumor-specific drug delivery are key challenges in improving therapeutic outcomes. This study aimed to develop actively targeted cyclodextrin-based nanoparticles co-loaded with gemcitabine (GEM) and paclitaxel (PCX) to improve efficacy against pancreatic cancer, particularly in drug-resistant phenotypes. Hyaluronic acid (HA) was used to functionalize the nanoparticles for CD44-mediated active targeting. Comprehensive physicochemical characterization including particle size, zeta potential, drug loading, release profile, and stability was conducted. In vitro studies covered both 2D monolayer and 3D spheroid models of pancreatic cancer, including drug-resistant Panc-1 cells. Apoptosis induction and cholesterol depletion were assessed for mechanistic evaluation. In vivo studies in tumor-bearing mice were performed for efficacy, biodistribution, and systemic safety. All nanoparticle formulations exhibited sub-200 nm diameters, high drug loading efficiencies (>50 %), and sustained release profiles. HA-functionalized nanoparticles demonstrated enhanced cellular uptake, significant cytotoxicity, and apoptosis in both drug-sensitive and resistant cells. In vivo, CD44 targeted dual-drug nanoparticles significantly inhibited tumor growth, showed enhanced intratumoral accumulation, and exhibited no systemic toxicity. These findings suggest that HA-functionalized amphiphilic cyclodextrin nanoparticles co-loaded with GEM and PCX represent a promising strategy to overcome chemoresistance and improve therapeutic efficacy in pancreatic cancer."

Owing to its anti-inflammatory properties, biocompatibility and ability to contribute to ECM remodeling, HA is considered a promising therapeutic candidate for neurodegenerative diseases. This review summarizes the application of HA to treat Alzheimer's disease (AD) and Parkinson's disease (PD) and outlines the current understanding of the mechanism of action and strategies for HA-based biomaterial modification. For AD, HA is involved in several mechanisms including stabilizing the perineuronal net, reducing the toxic effects of A\u03b2 and hyperphosphorylated tau, and modulating neuroinflammation through CD44/RHAMM signaling pathways. HA-based nanoparticles and hydrogels enhance drug delivery across the blood-brain barrier, facilitate A\u03b2 clearance, and enable sustained, controlled release of therapeutic agents. In PD, HA regulates autophagic flux, inhibits \u03b1-synuclein propagation, and remodels the ECM to protect dopaminergic neurons. Modifications such as HA hydrogels with neurotrophic factors improve cell transplantation outcomes, while conjugates enhance mitochondrial targeting and dopamine delivery. While numerous preclinical studies have shown promise, significant challenges remain, including the high variability of HA formulations, limited blood-brain barrier penetration efficiency, and a paucity of well-designed clinical trials to validate preliminary findings. Future directions include standardizing laboratory protocols, developing hybrid systems integrating vascular endothelial growth factor and gene therapy, and adopting a patient-specific approach that leverages HA's multi-targeted effects on the nervous system."

Growing interest has recently been drawn towards glycan structures on EVs. Hyaluronic acid (HA) is a negatively charged glycosaminoglycan that can decorate the surface of EVs from different origins. HA is a ligand for adhesion receptor CD44, which is overexpressed in various cancers and inflammatory diseases. Although HA has been utilised as a surface decoration to improve CD44-mediated targeting of synthetic nanoparticles and EVs, the role of CD44 in the uptake of EVs is not well known. To assess the importance of CD44 in the interactions and endocytosis of HA-decorated EVs, uptake of HA-decorated and nondecorated EVs into CD44-expressing and -deficient cells was investigated using microscopic methods. The uptake of HA-decorated EVs was significantly increased into cells that expressed CD44, but no differences in endocytosis mechanisms were found. Additionally, the formation of plasma-derived protein corona in HA-decorated and nondecorated EVs was investigated using multi-parametric surface plasmon resonance and mass spectrometry. HA-decoration was found to cause a formation of thicker corona and enrichment of plasma-derived protein corona components. These findings highlight the role of HA in enhancing CD44-mediated EV targeting and modulating the composition of protein corona."

To identify potential biomarkers, we profiled miRNA expression in serum, saliva, and vaginal mucus from 20 women (10 with endometriosis and 10 controls) using next-generation sequencing. Differentially expressed miRNAs were identified, and their predicted targets underwent Gene Ontology and KEGG pathway enrichment analyses. Serum proteomics by data-independent acquisition LC\u2013MS/MS was integrated with miRNA data to construct potential miRNA\u2013protein interaction networks. Distinct miRNA profiles were observed across the three bodily fluids, with serum showing the most abundant miRNAs and saliva the lowest.

Identifying new biomarkers for early cancer detection could improve treatment outcomes. Tumor-derived cells release extracellular vesicles (EVs) carrying tumor-specific molecular signatures, which can help distinguish patients with cancer even in early stages. The aim of this study was to assess the potential of EVs as biomarkers to enhance cancer detection in patients with PNS. This observational and multicenter study included 27 patients with tumor-associated PNS, 26 with suspected PNS without a tumor, 35 with cancer, and 32 healthy controls. Subsequently, among the patients with PNS, individuals were subclassified according to the PNS-Care Score as definite, probable, possible, and non-PNS. Total EVs were isolated from blood by precipitation and from B cells, T cells, and neurons by immunoisolation. To identify a biomarker for diagnostic refinement and clinical stratification, EV levels, size, and protein content were compared across study groups. To find a tumor biomarker in intermediate-risk cases, the possible association between EV protein content and cancer detection in intermediate-risk syndromes was analyzed. Patients with tumor-associated PNS showed significantly higher circulating EV levels compared with those with suspected PNS without evidence of a tumor (p = 0.028). Moreover, total EV levels, along with B cell-derived EVs, effectively differentiated patients with definite PNS from those with probable (p = 0.05) and possible (p = 0.006) PNS. A cutoff value of 2.10 \u00d7 1010 particles/mL EVs was identified, above which diagnosis of PNS was definite, with 86% sensitivity and 81% specificity. Proteomic analysis identified specific proteins, including ACADM, HPT, ACTBL, and CCAR2, as markers of definite PNS, differentiating such patients from those with probable and possible PNS, contributing to diagnostic refinement for clinical stratification. It is important to note that increased levels of EVs and CD44 distinguished intermediate-risk cases with tumors from those without. EVs may act as tumor biomarkers in patients with PNS, even in intermediate-risk cases. This study provides Class IV evidence that higher circulating blood levels of EVs can distinguish between tumor-associated PNS from suspected PNS without tumor."

The proposed work aims to develop a nanosystem based on gold nanoparticles (AuNPs) to actively target human endometriosis CD44(+) cells and significantly reduce their viability by photothermal therapy (PTT). AuNPs stabilized by lipoic acid-Poly(ethylene glycol)-Maleimide (LA-PEG-Mal) (Au@P) were decorated with antiCD44 antibodies (Au@P_AbCD44) through maleimide chemistry. The physicochemical and biochemical approaches revealed the presence of the antibody on Au@P_AbCD44. The in vitro studies were conducted against overexpressing CD44 cells (12Z), low-expressing CD44 cells (HESC), and the normal fibroblast cell line (NIH-3T3). Following the internalization through the clathrin-mediated endocytosis, the PTT of the cell-internalized Au@P_AbCD44 was investigated using two distinct laser types, due to the differing Au@P's LSPR properties. Au@P_AbCD44 exhibited significant PTT efficacy against 12Z cells; however, GNS@P_AbCD44 required lower energy input compared to GNP@P_AbCD44. This enhanced performance is attributed to the LSPR-mediated photothermal conversion efficiency of GNS over GNPs.In both cases, the apoptotic pathway was selected by dying cells over necrotic cells. The results revealed a better photothermal ability of GNS@P_AbCD44 compared to GNP@P_AbCD44. Our findings highlight the clinical potential of gold nanostars as advanced photosensitizers for targeted photothermal therapy, offering a promising strategy for more effective and less invasive treatment of endometriosis."

Here, we report the labeling of both hydrogels and EVs to better understand hydrogel design for sustained EV release into tissues. Shear-thinning hydrogels were engineered using guest-host (i.e., adamantane-cyclodextrin) modifications to hyaluronic acid (GH), as well as GH hydrogels with the addition of gelatin crosslinked via transglutaminase (GH+Gel) to temporally control hydrogel properties. When labeled with a near-IR dye and injected into rat myocardial tissue, the GH+Gel hydrogel was retained (>14 days) longer than the GH hydrogel alone (~7 days), likely due to the added gelatin network. To overcome challenges associated with common EV labeling methods, we utilized a highly versatile metabolic labeling methodology via the incorporation of Ac4ManNAz during EV synthesis to introduce azide groups that could then be reacted with DBCO-dyes. When injected in saline, EVs were cleared within 24 hours in hearts; however, hydrogels enhanced EV retention, with levels based on hydrogel degradation behavior, namely >14 days for GH+Gel hydrogel and ~7 days for GH hydrogel alone. These findings support the use of hydrogels in EV therapies to help retain their presence at desired tissue sites."

Emerging evidence suggests endometrial stem cells (EnSCs) contribution in disease pathogenesis, including mesenchymal stem cells (E-MSCs), epithelial progenitor cells (EPCs), and side population cells (ESPs). These stem/progenitor cells are involved in proliferation, migration, and angiogenesis, contributing to endometriosis genesis and persistence. Targeting EnSCs and their regulatory pathways present a promising therapeutic strategy to improve unmet needs in endometriosis. This scoping review was based on a systematic literature search conducted in PubMed, EMBASE, and Web of Science considering studies published after 2000. Inclusion criteria focused on original research articles exploring the role and targeting of EnSCs in endometriosis, following PRISMA-ScR guidelines. Data were synthesized through narrative and descriptive methods. The review structures key pathways and therapeutic agents targeting EnSCs in endometriosis. Notch1, PI3K/Akt, Wnt/\u03b2-catenin, and JAK/STAT signalling are pathways that regulate proliferation, migration and survival of EnSCs in endometriosis. Agents such as metformin, lovastatin, sorafenib, quinagolide, and \u03b3-secretase inhibitors demonstrated potential to modulate stemness, leading to a decrease in inflammation, migration and apoptosis. Anti-angiogenic agents showed efficacy in reducing lesion size In vivo, targeting E-MSCs.

HA-iMSC-EVs showed typical characteristics for EVs such as morphology, size, and marker proteins expression. Compared with iMSC-EVs, HA-iMSC-EVs showed enhanced tube formation and survival against oxidative stress in endothelial cells, while reduced reactive oxygen species (ROS) generation in cardiomyocytes. In THP-1 macrophages, both types of EVs markedly reduced the expression of pro-inflammatory signaling players, whereas HA-iMSC-EVs were more potent in augmenting anti-inflammatory markers. A significant decrease of inflammasome proteins was observed in HA-iMSC-EV-treated THP-1. Further, phospho-SMAD2 as well as fibrosis markers in TGF-\u03b21-stimulated cardiomyocytes were reduced in HA-iMSC-EVs treatment.

Echocardiography revealed that intramyocardial HA-iMSC-EVs injections improved cardiac function and reduced adverse cardiac remodeling and necrotic size in MI heart. Histologically, MI hearts receiving HA-iMSC-EVs had increased capillary density and viable myocardium, while showed reduced fibrosis. Our results suggest that HA-iMSC-EVs improve cardiac function by augmenting vessel growth, while reducing ROS generation, inflammation, and fibrosis in MI heart."

These HA-EVs exhibited superior targeting of CD44-expressing cells, including pro-inflammatory macrophages and senescent dermal fibroblasts, thereby effectively suppressing inflammatory responses and restoring fibroblast function in a wound-healing mouse model.

A method for isolating sEVs from cow milk was optimized, and the obtained sEVs were fully characterized in terms of size, morphology, and protein markers.

Extracellular vesicles (EVs), derived from tumor cells, have the remarkable ability to home back to their cells of origin and can serve as Trojan horses for drug delivery. CD44, a cell surface glycoprotein, promotes cancer stem cell-like properties and is linked to poor prognosis and resistance to chemotherapy in HCC. Therefore, targeting CD44-expressing HCC cells is of interest in the development of novel therapeutic strategies for the treatment of HCC. In this study, we developed tumor cell-derived EVs (TEVs) functionalized with hyaluronic acid (HA) to serve as natural carriers for the precise delivery of doxorubicin (Dox), which specifically targets HCC cells expressing CD44. Our results demonstrated that HA-engineered EVs (HA-EVs) significantly enhanced Dox accumulation within HCC cells. In a mouse model, HA-EVs effectively delivered Dox to tumors, suppressing their growth and progression while minimizing systemic toxicity. This study demonstrates the potential of HA-functionalized EVs as a novel and targeted therapeutic platform for HCC, offering a valuable strategy for improving drug delivery and patient outcomes. This study presents a promising strategy to advance targeted chemotherapy for HCC and address the challenges associated with conventional treatments. Engineered HA-functionalized EVs offer a tailored and efficient approach to increase drug delivery precision, underscoring their potential as a novel therapeutic platform in the realm of HCC treatment."

Current treatments often face challenges including limited targeting efficacy and systemic side effects. To develop a novel targeted therapy for RA, this study constructed a functionalized extracellular vesicle (EV) system by engineering ginseng stems and leaves-derived EVs with hyaluronic acid (HA) modification and curcumin (Cur) loading (Cur@EVs-PH). Structurally, the EVs-PH drug-loaded nanoplatform integrates the remarkable anti-inflammatory and antioxidant properties of EVs with the prolonged circulation capacity conferred by PEG. This design further capitalizes on the targeting ability of HA, thereby providing a robust structural foundation for the efficient delivery of therapeutics to disease sites. Our results demonstrated that the designed system achieved enhanced inflammatory targeting through CD44 receptor-mediated accumulation and exhibited potent anti-inflammatory and antioxidant activities. In the collagen-induced arthritis model, Cur@EVs-PH significantly alleviated joint swelling, reduced pathological scores and normalized immune organ indices. Mechanistic studies revealed that the therapeutic effects were mediated through suppression of pro-inflammatory cytokines and promotion of macrophage M2 polarization. This integrated strategy combining natural EVs, targeted modification and active drug loading provides a promising platform for the treatment of RA and other inflammatory diseases."

To address these challenges, we engineered a targeted co-delivery platform by systematically comparing two representative, probiotic-derived extracellular vesicle carriers: outer membrane vesicles (OMVs) from Escherichia coli Nissle 1917 and extracellular vesicles (EVs) from Lactobacillus plantarum. Encapsulation efficiency (EE) of Cur was 41.6% for OMVs and 35.9% for EVs, whereas EE of Ant was 25.4% and 24.6%, respectively. Both vesicle types were further synergistically functionalized with specifically acylated epigallocatechin palmitate (EGCp) and octenyl succinic anhydride-grafted hyaluronic acid (OSA-HA). The incorporation efficiency of EGCp was 27.2% for OMVs and 37.3% for EVs. The self-assembly process yielded composite nanovesicles with a reduced particle size (OMVs: from 165.6\u00a0nm to 143.2\u00a0nm; EVs: from 156.8\u00a0nm to 120.8\u00a0nm) and a more negatively charged surface (from -20.8\u00a0mV to -37.5\u00a0mV for OMVs; from -18.3\u00a0mV to -35.3\u00a0mV for EVs) compared to their native counterparts, indicating improved colloidal properties. In addition, both engineered nanovesicles effectively protected the encapsulated bioactives, significantly enhancing their stability against simulated gastrointestinal digestion and oxidative stress. For example, the retention of Cur under oxidative conditions increased from 24.2% in unmodified OMVs to 69.1% in the optimized formulation within 2\u00a0h. Cellular uptake assays confirmed the OSA-HA coating achieved targeted delivery to inflammatory macrophages, with OSA-HA-modified OMVs exhibiting higher cellular internalization (75.4% at 12\u00a0h) than similarly modified EVs (61.8% at 12\u00a0h). While both types of functionalized nanovesicles enhanced intracellular antioxidant activity to a similar extent, the OMV-based system demonstrated superior suppression of pro-inflammatory mediators (NO, TNF-\u03b1, and IL-6) in mitigating lipopolysaccharide (LPS)-induced cell damage. This comparative study establishes a biocompatible probiotic-based colloidal platform, demonstrating the potential of two selected engineered probiotic vesicles and functionalized polysaccharides for the encapsulation and targeted cellular delivery of sensitive bioactive compounds."

Overcoming drug resistance and enhancing tumor-specific drug delivery are key challenges in improving therapeutic outcomes. This study aimed to develop actively targeted cyclodextrin-based nanoparticles co-loaded with gemcitabine (GEM) and paclitaxel (PCX) to improve efficacy against pancreatic cancer, particularly in drug-resistant phenotypes. Hyaluronic acid (HA) was used to functionalize the nanoparticles for CD44-mediated active targeting. Comprehensive physicochemical characterization including particle size, zeta potential, drug loading, release profile, and stability was conducted. In vitro studies covered both 2D monolayer and 3D spheroid models of pancreatic cancer, including drug-resistant Panc-1 cells. Apoptosis induction and cholesterol depletion were assessed for mechanistic evaluation. In vivo studies in tumor-bearing mice were performed for efficacy, biodistribution, and systemic safety. All nanoparticle formulations exhibited sub-200 nm diameters, high drug loading efficiencies (>50 %), and sustained release profiles. HA-functionalized nanoparticles demonstrated enhanced cellular uptake, significant cytotoxicity, and apoptosis in both drug-sensitive and resistant cells. In vivo, CD44 targeted dual-drug nanoparticles significantly inhibited tumor growth, showed enhanced intratumoral accumulation, and exhibited no systemic toxicity. These findings suggest that HA-functionalized amphiphilic cyclodextrin nanoparticles co-loaded with GEM and PCX represent a promising strategy to overcome chemoresistance and improve therapeutic efficacy in pancreatic cancer."

It is characterised by ectopic (ECT) growth of endometrial-like tissue mainly in the pelvic cavity. Small extracellular vesicles (sEVs) mediate cellular interactions, but their function remains poorly understood in the pathogenesis of EM. 3D endometrial epithelial organoids (EEOs) from ECT lesions and eutopic (EUT) endometrium from EM patients and controls were established to investigate sEVs. Multiplex bead-based flow cytometry revealed CD133/1 and EpCAM as dominant markers on EEO-sEVs, with ECT EEO-sEVs showing upregulation of CD44, CD29 and downregulation of EpCAM compared to EUT EEO-sEVs. Peritoneal fluid (PF)-sEVs displayed high and correlated CD133/1 and EpCAM expression, indicating a major contribution from endometrial epithelial (EE) cells, alongside sEVs of lymphocyte and endothelial origin. Functionally, both ECT EEO-sEVs and PF-sEVs from EM patients significantly suppressed macrophage phagocytosis, as assessed by pH-sensitive fluorescent bioparticles. The effect was reversed by CD47 blockade. The coexpression of CD47 with CD133/1 and EpCAM on PF-sEVs indicates the involvement of EE cell-derived sEVs in CD47/SIRP-\u03b1 mediated suppression. This study provides the first thorough characterisation of EE-derived sEVs utilising EEO models in EM and demonstrates their potential immunomodulatory role in the peritoneal microenvironment via CD47/SIRP-\u03b1 signalling."

To overcome these challenges, we introduce Ag@PEG2000-HA nanoclusters (NCs), novel silver-based NCs developed through a sequential functionalization process using polyethylene glycol (PEG) and hyaluronic acid (HA). The HA-induced stabilization enlarges nanocluster cores and promotes ligand-metal charge transfer, synergizing with size-dependent aggregation-induced emission (AIE) effect to amplify fluorescence. These developed nanoconstructs showcase enhanced theranostic capabilities, featuring strong near-infrared (NIR) fluorescence for live tumor imaging and reactive oxygen species (ROS)-enabled mitochondrial targeting to induce cancer cell apoptosis selectively. Systematic evaluations, both in vitro and in vivo, confirmed significant tumor growth inhibition, increased survival rates, and a positive biosafety profile. The dual-targeting approach, leveraging the enhanced permeability and retention (EPR) effect alongside HA-mediated CD44 interaction, ensures precise tumor targeting and reduces off-target effects. Additionally, the nanoclusters showed exceptional stability, extended blood circulation, and resistance to macrophage phagocytosis, thereby enhancing their therapeutic effectiveness. Detailed mechanistic studies showed that Ag@PEG2000-HA NCs trigger apoptosis via ROS production and mitochondrial disruption, and concurrently reduce the expression of key tumor-associated proteins (CD31, Ki-67, and MMP9), inhibiting angiogenesis, proliferation, and metastasis. This research establishes a multifunctional nanoplatform bridging diagnostic imaging and therapy, opening new avenues for precision oncology. The findings provide fundamental insights into the design principles of cluster-based theranostic nanomaterials, paving the way for their clinical translation in cancer treatment."

The diagnosis of EM is historically hampered by delays, owing to the absence of reliable diagnostic and monitoring techniques. Herein, it is reported that photoacoustic imaging can be a noninvasive modality for deep-seated EM by employing a hyaluronic-acid-modified polydopamine (PDA@HA) nanoparticle as the contrast agent. The PDA@HA nanoparticles exhibit inherent absorption and photothermal effects when exposed to near-infrared light, proficiently converting thermal energy into sound waves. Leveraging the targeting properties of HA, distinct photoacoustic signals emanating from the periphery of orthotopic EM lesions are observed. These findings are corroborated through anatomical observations and in vivo experiments involving mice with green fluorescent protein-labeled EM lesions. Moreover, the changes in photoacoustic intensity over a 24 h period reflect the dynamic evolution of PDA@HA nanoparticle biodistribution. Through the utilization of a photoacoustic ultrasound modality, in vivo assessments of EM lesion volumes are conducted. This innovative approach not only facilitates real-time monitoring of the therapeutic kinetics of candidate drugs but also obviates the need for the sacrifice of experimental mice. As such, this study presents a promising avenue for enhancing the diagnosis and drug-screening processes of EM."

Sorafenib, a multikinase inhibitor of RAF/VEGFR/PDGFR, can suppress these pathways, but its clinical utility is limited by hydrophobicity, toxicity, and poor tumor penetration. We engineered hyaluronic acid-coated niosomes encapsulating sorafenib (SOR@Nio/HA) to enable CD44-targeted delivery to OSCC cells. SOR@Nio/HA displayed a mean hydrodynamic diameter of 177\u00b18 nm (PDI=0.23-0.26) and high encapsulation efficiency (86.34%), with pH-responsive release (45% at pH=5.5 and 30% at pH=7.4, in 24 hr).

Celastrol (Cel)'s oral translation is limited by poor bioavailability and lack of lesion-specific targeting. To overcome these barriers, we constructed a hyaluronic acid (HA)-functionalized platform featuring dual enzyme/ROS-triggered release and CD44-mediated active targeting (HA@Cel/NPs) for treating ulcerative colitis (UC), colitis-associated colorectal cancer (CAC), and colon cancer. HA@Cel/NPs were fabricated using \u03b2-cyclodextrin and 4-(hydroxymethyl) phenylboronic acid as dual-responsive linkers. Physicochemical properties, drug release profiles, cellular uptake, anti-inflammatory activity, macrophage polarization, and anticancer activity were systematically evaluated in vitro. In vivo biodistribution and therapeutic efficacy were assessed in UC, CAC, and colon cancer mouse models, with anti-PD-L1 combination therapy in the colon cancer setting. HA@Cel/NPs exhibited uniform size (76.87 \u00b1 2.65 nm, PDI 0.166 \u00b1 0.012), stayed stable for 14 days, and achieved ~71% Cel release under high H2O2/\u03b1-amylase conditions within 8\u00a0h.

This review examines studies published from 2019 to 2026, with emphasis on high-quality research in leading journals, and connects the structural parameters of HA with quantitative drug delivery efficiency and therapeutic performance. The major HA-based carrier systems, including micelles, liposomes, polymeric nanoparticles, metal-organic frameworks, and electrospun fiber systems, are critically analyzed in relation to HA molecular weight, degree of substitution, and ligand density, as well as their effects on hydrodynamic size, zeta potential, colloidal stability, and cellular uptake. Across these studies, the most effective designs generally feature nanoscale dimensions that balance circulation and tumor penetration while maintaining near-neutral or slightly negative surface potentials to minimize nonspecific interactions, highlighting the importance of rational physicochemical design for improving therapeutic performance.
Quantitative models of drug release, together with in vitro potency indices such as half-maximal inhibitory concentration (IC50) and combination index, as well as in vivo pharmacokinetic and efficacy indicators including half-life, area under the curve (AUC), and tumor-to-organ ratio, demonstrate how the configuration of HA influences therapeutic selectivity and systemic safety. To improve the rigor and reproducibility of future studies, this review further proposes a concise reporting framework integrating materials characterization, biological evaluation, and animal experiments, while highlighting the current limitations in standardization and cross-study comparability.
In conclusion, this review summarizes the current design principles of HA-based nanocarriers while critically discussing the remaining challenges, including CD44 heterogeneity, microenvironmental competition, and the lack of standardized evaluation strategies. Together, these perspectives provide practical guidance for the rational design, comparative evaluation, and clinical translation of next-generation HA-based nanocarriers.

The field is scientifically attractive because cancer cells and tumor-associated stromal cells remodel their glycocalyx, overexpress selected carbohydrate-recognizing receptors and display altered metabolic demand; however, the translation of glycoengineered nanomedicine remains limited by low tumor delivery efficiency, heterogeneous receptor density, competitive off-target uptake by liver and macrophages, batch-to-batch variation in ligand density and insufficient quantitative reporting. This review re-frames carbohydrate-mediated cancer drug delivery as an evidence-weighted design problem. It integrates receptor-density data, particle-size boundaries, ligand-density ranges, release-rate targets, in vitro uptake metrics, pharmacokinetic endpoints and preclinical efficacy readouts into a quantitative framework. Special attention is given to hyaluronic acid-CD44, galactose/GalNAc-ASGPR, mannose-CD206, sialylated glycan-siglec/selectin, beta-galactoside-galectin and glucose/GLUT-related approaches, with emphasis on what the available data can and cannot prove. The central conclusion is that molecular glycoengineering is most defensible when carbohydrate chemistry is linked to measurable receptor engagement, competitive inhibition, uptake kinetics, intracellular drug exposure and statistically stronger antitumor benefit rather than to generic claims of active targeting. The framework explicitly links anomeric configuration, glycosidic linkage, branching, sulfation/acetylation, epitope display and glycan-protein hydration to receptor-specific pharmacological outcomes, thereby shifting the emphasis from general nanomedicine performance to carbohydrate structure-activity relationships required for a carbohydrate-chemistry readership."

Although they share several molecular features, the mechanisms by which endometrium-derived tissues develop distinct pathological phenotypes in different tissue environments remain incompletely understood. This review summarizes shared and divergent pathogenic mechanisms, focusing on lesion-specific microenvironments. This narrative review was based on a PubMed literature search from the year of the first publication through December 2025 using terms related to endometriosis, adenomyosis, mitochondrial function, oxidative stress, fibrosis, mechanical stress, and calcium signaling. Both disorders develop in the context of repetitive tissue injury, estrogen-dependent repair responses, chronic inflammation, oxidative stress, and mitochondrial dysfunction. However, differences in lesion location and microenvironment appear to drive distinct pathological phenotypes. In superficial peritoneal endometriosis and ovarian endometrioma, mitochondrial adaptation primarily supports hypoxia tolerance, oxidative stress responses, angiogenesis, cellular survival, and metabolic reprogramming. In contrast, deep infiltrating endometriosis and adenomyosis are characterized by fibrosis, extracellular matrix remodeling, tissue stiffening, and adaptation to mechanical stress. In adenomyosis, mitochondrial regulation of calcium homeostasis, smooth muscle contractility, reactive oxygen species production, and TGF-\u03b2-related fibrotic signaling may play important roles in disease progression. We propose a proliferation-fibrosis divergence model in which common pathogenic stimuli are integrated through mitochondria-dependent responses to distinct local microenvironments. Mitochondria may act as central regulators linking hypoxic adaptation, inflammation, metabolism, fibrosis, and mechanotransduction, thereby influencing whether disease progression favors proliferative expansion or fibrotic remodeling. This framework may provide a basis for future mechanism-based precision therapeutic strategies."

This study examined the effects of TSS on fecundity and endometriosis-like lesions during pregnancy in a murine model of endometriosis. Endometriosis model mice were divided into four groups: Sham operation\u202f+\u202fcontrol diet (Sham/Cont), Sham operation\u202f+\u202f3% TSS diet (Sham/TSS), Endometrium dispersion\u202f+\u202fcontrol diet (End/Cont), and Endometrium dispersion\u202f+\u202f3% TSS diet (End/TSS). Mating was initiated one day after surgery, and females were sacrificed on postpartum day 3. Endometriosis-like lesion size, inflammatory cytokine levels, and reproductive outcomes were evaluated. Time to delivery tended to be shorter in the End/TSS group than in the End/Cont group (median: 23.5 vs. 27 days), although the difference was not statistically significant. The maximum lesion diameter in the End/TSS group was significantly smaller compared to the End/Cont group (median: 4.54\u202fmm vs. 7.76\u202fmm, p\u202f=\u202f0.044).

A growing body of evidence points to non-hormonal molecular networks including immune dysregulation, angiogenesis, and resistance to apoptosis as drivers of lesion persistence. These molecular disturbances are associated with treatment resistance and limit the long-term efficacy of hormone-based therapies. This review synthesises recent mechanistic advances that describe the non-hormonal signalling pathways that maintain endometriotic lesions, with a specific emphasis on NF-\u03baB-mediated sterile inflammation, inflammasome activation, PI3K/Akt/mTOR-dependent survival signalling, Hedgehog-driven fibrosis and epigenetic repression of progesterone receptor expression. Steroidal alkaloids are critically reviewed as multitarget modulators suppressing inflammatory signalling, inhibiting invasive and fibrotic remodelling, and restoring apoptotic sensitivity in this pathophysiological context, without direct systemic oestrogen deprivation. Structural determinants of steroidal alkaloid activity, including glycosylation status, nitrogen topology and configuration of the steroidal scaffold, are discussed in the context of pathway selectivity, pharmacokinetics and toxicity. Preclinical in vitro and in vivo evidence is critically reviewed in the context of key translational limitations such as bioavailability constraints, narrow therapeutic index and teratogenic risk from developmental pathway inhibition. This review highlights steroidal alkaloids as a mechanistically rational, non-hormonal approach to target lesion persistence and fibrosis in endometriosis, integrating molecular, pharmacological and structural insights, and outlines the major hurdles that must be overcome for clinical translation. The main objective of this review is to address a specific unanswered question: can steroidal alkaloids with their multitarget pharmacology offer a biologically coherent, non-hormonal strategy for the treatment of endometriosis that goes beyond oestrogen deprivation to target the molecular machinery of lesion survival, fibrosis and immune dysregulation. This question is addressed by reviewing the nonhormonal signalling networks that support ectopic lesions, the structural and pharmacokinetic properties of steroidal alkaloids that are relevant to these pathways, and the translational challenges that need to be addressed for clinical translation."

In this study, we designed a hyaluronic acid-based prodrug system, HA-Ns-Dox, that integrates receptor-mediated cellular uptake with intracellular glutathione (GSH)-responsive activation. A doxorubicin (Dox) prodrug modified with a 2-nitrobenzenesulfonyl (Ns) group was synthesized and subsequently conjugated to hyaluronic acid (HA) via click chemistry to generate HA-Ns-Dox with both CD44-targeting capability and GSH-responsive activation properties. HA-Ns-Dox formed stable nanosized assemblies in aqueous solution and exhibited high stability under low-GSH conditions mimicking extracellular environments, whereas concentration-dependent activation of Dox was observed under high-GSH conditions mimicking intracellular reductive environments. In vitro studies demonstrated that HA-Ns-Dox was selectively internalized into the CD44-high human breast cancer cell line MDA-MB-231, accompanied by intracellular prodrug activation and nuclear accumulation of Dox. In contrast, cellular uptake and activation were minimal in the CD44-low cell line MCF-7, and cytotoxicity was significantly suppressed even at high concentrations. Cytotoxicity studies further revealed that HA-Ns-Dox exhibited significant antiproliferative activity in CD44-high cells while substantially reducing toxicity toward non-target cells. Collectively, these findings demonstrate the potential of combining CD44-targeted delivery with GSH-responsive prodrug activation to improve cancer cell selectivity."

High recurrence rates and enduring symptoms despite current treatments underscore the need for a more thorough understanding of its intricate biology. There is growing evidence that the interaction among oxidative stress (OS), microbiome dysbiosis, and epigenetic dysregulation contributes to immunological activation, hormonal imbalance, and the persistence of ectopic lesions. Important disease mechanisms, such as progesterone resistance, inflammatory signaling, and aberrant cellular proliferation, are influenced by epigenetic changes, which include aberrant DNA methylation, histone modifications, and dysregulated non-coding RNAs. Simultaneously, high levels of reactive oxygen species (ROS) reinforce lesion survival and chronic inflammation by promoting angiogenesis, fibrosis, and tissue damage. Changes in the microbiome also affect immunological responses, oxidative balance, estrogen metabolism, and epigenetic control, indicating the existence of interrelated pathogenic loops. This narrative review presents an integrated mechanistic framework for endometriosis, summarizing the available data that connect these pathways. Furthermore, the growing implications of non-invasive biomarkers and precision medicine techniques highlight the potential for improved diagnosis, disease classification, and targeted treatment approaches."

In this study, hyaluronic acid (HA) and glycyrrhetinic acid (GA) were separately conjugated to D-alpha tocopherol acid polyethylene glycol succinate (TPGS), which subsequently self-assembled into nanoparticles (HA/GA-NPs). Bletilla striata polysaccharide (BSP) and HA were employed as the microneedle matrix to fabricate soluble microneedles incorporating the nanoparticles (HA/GA-NPs-MNs). This strategy combined the CD44-targeting capability and anti-inflammatory activity of the nanoparticles with the immunomodulatory function and efficient penetration-enhancing ability of the BSP-based microneedles, thereby achieving synergistic therapeutic effects against psoriasis. In vitro studies demonstrated that the CD44-targeting capability of HA/GA-NPs enhanced cellular uptake, reduced intracellular ROS expression, and suppressed the inflammatory proliferation of HaCaT cells. Concurrently, BSP and HA/GA-NPs synergistically promote M2 polarization in RAW264.7 cells while suppressing the production of NO and proinflammatory factors IL-6, TNF-\u03b1, and IL-1\u03b2. Furthermore, HA/GA-NPs-MNs enhanced drug accumulation and skin penetration, enabling efficient delivery into the deeper skin layers. During in vivo studies, the system was observed to significantly enhance immune regulation and demonstrated the strongest efficacy in suppressing psoriatic inflammatory infiltration. The primary therapeutic mechanism of HA/GA-NPs-MNs against psoriasis involved the blockade of STAT3 phosphorylation to inhibit IL-23 signaling and downstream IL-17 release. The biosafety assessment confirmed high dermal and hemocompatibility of the system.

Clinical treatments face major challenges, including postoperative recurrence, refractory bone defects, and inadequate targeting of chemotherapeutic drugs. Hyaluronic acid (HA), a natural component of the human extracellular matrix, serves as an ideal material for integrating osteosarcoma therapy and postoperative bone regeneration, attributed to its unique properties including CD44-mediated tumor targeting, tumor microenvironment-responsive degradation, excellent biocompatibility, and functional tunability. This review summarizes recent advances in HA-based materials for osteosarcoma therapy. HA acts as a versatile carrier for chemotherapeutic drugs (e.g. doxorubicin (DOX), cisplatin (CDDP)) and therapeutic nucleic acids, via nanoparticles, liposomes, or hydrogels. These carriers enhance intratumoral drug accumulation, reduce systemic toxicity, evade immune recognition, and facilitate intracellular drug delivery. Incorporating bioactive glass or magnesium-based nanomaterials into HA constructs a multifunctional therapy-regeneration system, which simultaneously inhibits tumor growth and promotes bone regeneration, addressing postoperative bone defects. Furthermore, we analyze key obstacles to clinical translation, such as rapid degradation, insufficient hydrogel mechanical strength, and poor sterilization compatibility, and propose solutions including chemical cross-linking and composite modification. These insights provide valuable guidance for the precise design of HA-based biomaterials and their clinical translation, aligning with the demand for therapy-repair integration in regenerative medicine."

The cavity left after tumor resection represents a valuable opportunity to deliver therapeutics locally via the placement of conformable scaffolds for the immediate chemotherapeutic targeting of GSCs and residual glioblastoma cells. We hypothesized that Surgiflo\u2122, a moldable, FDA-approved gelatin-based hemostatic paste, could serve as a dual-purpose platform that minimizes postoperative bleeding and functions as a conformable, local, and sustained drug-delivery system. We incorporated a pH-sensitive designed hyaluronic acid-doxorubicin polymer-drug conjugate (HA-DOX) into the Surgiflo\u2122 matrix, exploiting HA's selective affinity for CD44 (highly expressed by both GBM and GSCs) and promoting the depletion of GBM and GSCs via immunogenic cell death (ICD)-inducing properties of DOX. In vitro studies of HA-DOX-containing paste confirmed enhanced HA-DOX uptake in GSC-enriched models, improved ICD induction in GBM cells, favorable biocompatibility, and sustained drug release. In vivo evaluations revealed that intracavitary implantation of the HA-DOX-containing paste significantly prolonged the median survival of treated mice compared to the untreated group (37 days vs 25 days, respectively) and modulated the glioblastoma-associated TIME, resulting in a 44% reduction in GSC levels and a significant increase in CD8+ T cell levels (\u2217p\u00a0<\u00a00.5), compared to resected mice.

Although gemcitabine (GEM) is the gold standard for PC, the acquired resistance and severe myelosuppression limit clinical utility. It has been found that abnormal aerobic glycolysis may be responsible for drug resistance in PC. Disulfiram (DSF), a commonly used anti-alcoholic drug, possesses potent anti-tumor activity combined with copper. Nevertheless, poor water solubility and neurotoxicity restrict clinical applications. Therefore, our group modified the structure of DSF and synthesized a novel compound CPD12C15, which exhibited stronger anti-tumor activity and lower neurotoxicity than DSF. Nanoparticles with excellent release properties, modified with hyaluronic acid (HA) targeting CD44, which is highly expressed on pancreatic cells, can evade the removal of natural defense system and enhance tumor-targeting ability. Herein, CPD12C15 was loaded into HA-modified PLGA nanoparticles (HPC-NP) in order to improve the sustained release properties and active targeting ability.

Among the key design parameters of HA-based nanocarriers, molecular weight (MW) critically influences biological performance; yet the optimal MW remains controversial. Although higher MW is often assumed to enhance CD44 binding and targeting efficiency, evidence indicates that its effects are multidimensional, context-dependent, and frequently non-linear. This review systematically examines how the MW of HA regulates cellular uptake, active targeting, drug solubilization, release kinetics, biodegradation, immunomodulation, and translational potential. At the cellular level, HA MW modulates multivalent CD44 engagement and receptor clustering, often producing a bell-shaped relationship with internalization efficiency. At the tissue level, MW affects tumor accumulation through competing influences on receptor avidity, nanoparticle size, and systemic clearance. Lower-MW HA generally promotes barrier penetration, cellular uptake, and pro-inflammatory responses, whereas higher-MW HA enhances stability, anti-inflammatory signaling, and circulation time but may reduce uptake due to steric hindrance. Overall, optimal MW selection depends on nanocarrier design, disease context, and dominant biological barriers. This review provides a mechanistic framework to guide rational MW selection in next-generation HA-based nanotherapeutics."

For patients with advanced, unresectable disease, transarterial chemoembolization (TACE) is a recommended first-line locoregional therapy. However, its efficacy is constrained by the inherent limitations of conventional embolic materials-such as non-target embolization, vessel recanalization, and incomplete distal occlusion-and by the low intra-tumoral delivery efficiency of chemotherapeutic agents. Furthermore, the high prevalence of p53 mutations (~\u200930%) in HCC drives tumorigenesis and chemoresistance, creating a critical therapeutic gap, especially within the hypoxic tumor microenvironment. To address these multifaceted challenges, we developed an innovative theranostic platform, CHSA/NAT. This system combines a radiopaque, thermosensitive hydrogel (NAT) for precise, image-guided vascular occlusion with CD44-targeted, glutathione (GSH)-responsive chitosan/hyaluronic acid nanomicelles (CHSA), which enable the smart delivery of arsenic trioxide (ATO)-a potent agent with p53-mutant corrective activity. In vitro, ATO demonstrated superior cytotoxicity over doxorubicin against multiple HCC cells under hypoxia. In a p53-mutant PLC/PRF/5 subcutaneous model, CHSA-ATO achieved a tumor inhibition rate of 84.6%, significantly outperforming free ATO and doxorubicin, and effectively modulated apoptotic proteins (downregulating mutant p53/Bcl-2, upregulating Bax). Crucially, superselective administration of CHSA/NAT enabled successful embolization with clear radiological visualization in rat hepatic and renal arteries, demonstrating its precise image\u2011guided delivery and embolization capability. Most importantly, in an orthotopic rat HCC model, the combined treatment exhibited powerful synergistic efficacy, attaining a remarkable 96% tumor suppression rate and significantly prolonging survival, with a favorable safety profile.

Following this structural breach, a self-perpetuating 'vicious cycle' is triggered, driven by four interconnected axes: (1) Hormonal Dysregulation, characterised by local hyper-estrogenism, progesterone resistance, and a specific paracrine prolactin loop that drives reactive myometrial hypertrophy; (2) Immune-Hemostatic Crosstalk, where activated platelets and M2-polarised macrophages establish a pro-fibrotic niche via TGF-\u03b21 signalling; (3) Hypoxia and Neuroangiogenesis, where HIF-1\u03b1 stabilisation orchestrates metabolic reprogramming (Warburg effect) and the pathological sprouting of sensory nerves, underpinning chronic pain; and (4) Epigenetic Fibrosis, driven by the oestrogen-slug-VEGF axis and HDAC-mediated chromatin remodelling leading to epithelial-mesenchymal transition (EMT).

Paclitaxel (PTX), a first-line chemotherapeutic agent widely used in breast cancer, is widely used due to its potent mechanism of action against rapidly dividing cancer cells. However, its clinical application is significantly hindered by poor solubility, systemic toxicity, and associated adverse effects. Encapsulating PTX in polymeric nanoparticles presents a promising strategy to overcome these limitations by extending drug release, enhancing drug's bioavailability, and enabling active targeting. This review uniquely focuses on recent advances in surface-functionalized polymeric nanoparticles specifically engineered for targeted delivery of PTX in breast cancer therapy and consolidates their translational relevance and next-generation design considerations. Unlike general reviews on polymeric nanocarriers, this article specifically focuses on ligand-functionalized polymeric nanoparticles designed for active targeting of breast cancer cells, integrating biological rationale, receptor specificity, and translational relevance. Surface-engineered polymeric nanoparticles functionalized with ligands such as folic acid, hyaluronic acid, aptamers, and peptides can specifically target overexpressed receptors on cancer cells, including CD44, HER2, and folate receptors. These ligand-receptor interactions facilitate receptor-mediated endocytosis, enhancing intracellular drug delivery while minimizing systemic toxicity. The review highlights key design considerations, including ligand density, nanoparticle architecture, and multifunctionality of next-generation PTX nanocarriers.

Several studies substantiate this: \"HLC achieves targeted accumulation through specific binding between HA and CD44 receptors on tumor cells.\" Furthermore, the use of extracellular vesicles as drug delivery vehicles is well-documented: \"Extracellular vesicles (EVs) are gaining interest in regenerative medicine and biomaterials have been shown to extend EV bioavailability following delivery.\" \n\nThe efficacy of ginger-derived nanocarriers for endometriosis is supported by: \"Exosomes emerge as a cell-free approach, derived from menstrual stem cells (MenSCs) or ginger-based nanoparticles and exhibited properties essential for endometriosis treatment, directed to ectopic stem cells.\" Additionally, borneol is identified as a potent facilitator of transport in other tissues, such as ischemic stroke: \"borneol significantly promoted drug enrichment in the brain following the IN of this gel system.\" By merging these mechanisms\u2014targeting, delivery via plant-derived vesicles, and transport-enhancement\u2014the hypothetical platform is mechanistically plausible according to current nanomedicine design principles.\n\n### [DISCUSSION: NOVEL & OVERLOOKED]\n* CD44 is consistently overexpressed in ectopic endometrial tissues, making it a viable receptor for targeted nanotherapeutic strategies.\n* The use of plant-derived extracellular vesicles, specifically ginger-based, serves as a non-toxic, cost-effective, and biodegradable carrier platform.\n* Borneol is capable of significantly promoting drug enrichment in specific target tissues when combined with thermosensitive hydrogel or gel-based delivery systems.\n* Nanocarriers functionalized with HA effectively minimize nonspecific interactions while maintaining near-neutral or slightly negative surface potentials.\n* Anti-angiogenic therapy targeting the VEGF pathway is a recognized hallmark of non-hormonal endometriosis management.\n* Surgiflo\u2122 and other hydrogel matrices demonstrate the feasibility of local, sustained drug delivery in surgical or cavity environments.\n* The co-delivery of natural phytochemicals and chemotherapeutic agents via functionalized nanoplatforms addresses multi-target disease drivers while reducing systemic toxicity.\n\n### [EVIDENCE, METHODOLOGY & CITATIONS]\n1.

CD44-overexpressing cells compared to non-functionalized sEVs.\nThis study demonstrates the potential of HA-functionalized EVs as a novel and targeted therapeutic platform for HCC, offering a valuable strategy for improving drug delivery and patient outcomes.\nThis integrated strategy combining natural EVs, targeted modification and active drug loading provides a promising platform for the

M1-to-M2 macrophage polarization in inflamed macrophages, while inducing potent CT26 cell apoptosis.\nAcross these studies, the most effective designs generally feature nanoscale dimensions that

pathogenic loops.\nConcurrently, BSP and HA/GA-NPs synergistically promote M2 polarization in RAW264.7 cells while suppressing the production of NO and proinflammatory factors IL-6, TNF-\u03b1, and IL-1\u03b2.\nIncorporating bioactive glass or magnesium-based nanomaterials into HA constructs a multifunctional therapy-regeneration system, which simultaneously inhibits tumor growth and promotes bone regeneration, addressing postoperative bone defects.\nIn vivo evaluations revealed that intracavitary implantation of the HA-DOX-containing paste significantly prolonged the median survival of treated mice compared to the untreated group (37 days vs 25 days, respectively) and modulated the glioblastoma-associated TIME, resulting in a 44% reduction in GSC levels and a significant increase in CD8+ T cell levels (\u2217p < 0.5), compared to resected mice.\nOur research revealed that CPD12C15 combined with Cu (HPC-NP/Cu) could inhibit tumor proliferation, migration, invasion and induce apoptosis by suppressing the aerobic glycolysis pathway, which further inhibited cell stemness and drug resistance in vivo and in vitro, suggesting that it may be a potential strategy for PC treatment.\nThis review provides a mechanistic framework to guide rational MW selection in next-generation HA-based nanotherapeutics.\nThis work presents a novel \"embolization\u2011imaging\u2011targeted chemotherapy\" strategy that simultaneously overcomes the key limitations of conventional TACE and ATO delivery, offering a promising and translatable nanoplatform for the effective treatment of advanced HCC.\nThis review synthesises current molecular evidence to propose a unified mechanistic framework initiated by tissue injury and repair (TIAR),

A targeted drug delivery system (HLC) was constructed using hyaluronic acid (HA) nanomicelles co-loaded with lactate oxidase (LOX) and copper-doped carbon dots (CuCDs). Combined with \u03b1-PD-L1, a synergistic antitumor strategy integrating lactate metabolic regulation, cuproptosis, and immune activation was established. HLC achieves targeted accumulation through specific binding between HA and CD44 receptors on tumor cells. It directionally releases LOX and CuCDs in the acidic TME via pH-responsive properties. LOX efficiently clears lactate and elevates pH, blocking the HIF-1\u03b1/PD-L1 pathway to reverse immunosuppression. It also generates H2O2 in situ to provide substrates for Cu-mediated Fenton-like reactions, enhancing cuproptosis. In vitro experiments confirm that HLC promotes dendritic cell maturation and drives M2-type macrophage polarization toward the M1 phenotype. In vivo studies using CT26 tumor-bearing mouse models show that HLC combined with 808\u202fnm laser and \u03b1-PD-L1 significantly inhibits primary and distant tumor growth. It remodels the antitumor immune microenvironment with favorable biosafety. This study elucidates the synergistic mechanism between lactate metabolic regulation and cuproptosis, establishes an association between lactate level and cuproptosis sensitivity, and provides a novel strategy and experimental basis for combined cancer immunotherapy with important clinical translation value."

Kidney diseases represent a major global health burden, often progressing to chronic complications due to the limited efficacy and poor selectivity of conventional therapies, which are frequently associated with systemic toxicity. Accordingly, the development of targeted drug delivery systems is essential to improve therapeutic outcomes. In this study, advanced quatsomes were developed as a kidney-targeted nanosystem to enhance the delivery of curcumin, a natural polyphenolic compound with potent antioxidant and nephroprotective properties. The system was composed of di-dodecyl-dimethyl-ammonium bromide (DDAB), cholesterol, limonene, hyaluronic acid (HA) and surfactants, and was fabricated using the ethanol injection method. A 23 factorial design was employed to optimize formulation variables, including DDAB:cholesterol ratio, limonene:drug ratio, and surfactant concentration. The optimized formulation (desirability = 0.950) exhibited high entrapment efficiency (87.80%), nanosized vesicles (120.55\u00a0nm), and a positive surface charge (+38.30\u00a0mV). Transmission electron microscopy confirmed spherical morphology, while in-vitro release studies demonstrated a biphasic profile. The formulation also showed good physicochemical stability and enhanced antioxidant activity. Mechanistically, passive targeting via nanoscale size and cationic charge facilitated interaction with the glomerular filtration barrier and mesangial uptake, while limonene improved vesicle deformability. HA functionalization further enabled CD44-mediated active targeting. In vivo, the optimized system significantly reduced serum creatinine and blood urea nitrogen levels in a cisplatin-induced nephrotoxicity model, with histological evidence of renal protection. Overall, the developed quatsomes demonstrate promising potential as an efficient renal-targeted nanocarrier."

To overcome these limitations, we developed an all-in-one prodrug nanoplatform based on hyaluronic acid (HA) that synergistically integrates active targeting, pH-responsive charge reversal, and controlled drug release. Doxorubicin (DOX) was covalently conjugated to oxidized HA via a pH-sensitive imine bond, while a charge-reversal polymer (PLL-DMMA) was grafted onto the HA backbone. This design enables CD44-mediated active targeting toward cancer cells. Crucially, the nanoplatform exhibits a smart charge-reversal characteristic: maintaining a negative surface charge (-32.8\u00a0mV) at physiological condition (pH 7.4) for extended circulation, while switching to positive (+16.5\u00a0mV) in the acidic tumor microenvironment (pH 6.5) to enhance cellular uptake. In vitro studies demonstrated significantly improved internalization in CD44-overexpressing MKN-45 cells compared to SNU-216 cells with low CD44 expression. The release profile showed high stability at pH 7.4 (<5% release in 5\u00a0days) and rapid drug release at endo/lysosomal pH (61.6% at pH 5.0). Cytotoxicity assays confirmed enhanced efficacy of the charge-reversed formulation, with lower IC50 values in both cell lines.

Twenty-eight adult female Wistar rats were randomized (n\u2009=\u20097/group) to sham group (G1), untreated endometriosis-group (G2), single-dose DP-MSCs-group (G3) (2\u2009\u00d7\u2009106 cells intraperitoneally on day 28) and double-dose DP-MSCs-group (G4) (2\u2009\u00d7\u2009106 cells on days 28 and 35). Endometriosis was induced by autologous uterine tissue implantation onto the peritoneal wall and allowed to establish for 28\u00a0days; treatment effects were assessed 7\u00a0days after the final DP-MSCs dose. Serum and peritoneal TNF-\u03b1, IL-6, VEGF, and CA-125 were quantified; lesions were evaluated by semi-quantitative histopathology and fibrosis grading and by immunohistochemistry for CA-125, VEGF, type I collagen (Col1), and TNF-\u03b1.

Due to its biocompatibility, biodegradability, non-toxicity and cluster of differentiation-44 (CD44) receptor-mediated targeting, it is widely used as a medical material in the fields of tissue engineering, regenerative medicine, and drug delivery systems (DDS). Herein, the latest research on HA-based medical materials over the past 5\u00a0years is systematically reviewed, focusing on the frontier advances on the utilization of HA and its derivatives in cartilage/skin regeneration, vitreous substitutes, and DDS. HA-based hydrogels can be used for articular cartilage regeneration by promoting the proliferation and differentiation of chondrocytes and the formation of ECM. As a vitreous substitutes, HA-based hydrogels have similar properties to natural vitreous humor. In the field of skin regeneration, HA has the ability to accelerate wound healing and construct complex skin substitutes. For DDS, different forms such as HA-drug conjugate nanoparticles (NPs), HA-surface modified NPs, nanomicelles, and hydrogels can be applied. The preparation methods, delivery mechanisms, in vitro and in vivo evaluations, and advantages of DDS are explained.

Based on this, our study report a targeted, stimuli-responsive nanoparticle system for the co-delivery of paclitaxel (PTX) and piperine (PIP) to achieve synergistic ovarian cancer therapy. PTX was chemically conjugated to polyamidoamine (PAMAM) dendrimers via a glutathione (GSH)-sensitive disulfide linkage, while PIP was physically encapsulated within the hydrophobic core of PAMAM. Hyaluronic acid (HA) was subsequently electrostatically assembled onto the nanoparticle surface to enable CD44-mediated tumor targeting. The resulting nanoparticles exhibited a uniform spherical morphology with an average diameter of approximately 145 nm and demonstrated dual responsiveness to elevated GSH and acidic pH conditions characteristic of the tumor microenvironments. In vitro and in vivo antitumor studies revealed that the co-delivery system significantly enhanced cytotoxicity and apoptosis through synergistic PTX/PIP activity compared with monotherapy. In addition, HA modification markedly improved cellular uptake and tumor accumulation, leading to effective tumor growth inhibition in vivo with reduced systemic toxicity. In conclusion, this study highlights a rationally engineered nanocarrier integrating active targeting and stimuli-responsive release, offering a promising materials-based strategy for synergistic ovarian cancer therapy."

Overcoming these obstacles requires a deep integration of renal physiopathology with advanced drug delivery engineering. This review provides a comprehensive analysis of the mechanisms governing kidney-targeted drug delivery. We first dissect the unique physiological barriers that dictate renal drug disposition, including the size- and charge-selective glomerular filtration barrier (\"the sieve\") and the high-capacity reabsorption machinery of the proximal tubule (e.g., megalin-mediated endocytosis). Subsequently, we elucidate the pathological alterations in the \"fibrotic niche\", highlighting emerging therapeutic targets such as the upregulated CD44 receptor and specific integrins on myofibroblasts. Based on this understanding, we systematically categorize current delivery strategies into two paradigms: (1) Passive Targeting, which exploits physicochemical properties (e.g., 75-100\u00a0nm size range for mesangial sequestration); and (2) Active Targeting, which utilizes ligand-receptor precision to direct carriers to the tubular epithelium (via megalin or transporters) or the fibrotic microenvironment (via hyaluronic acid or RGD [Arg-Gly-Asp]). Finally, we discuss the challenges of clinical translation, including interspecies differences and long-term nanotoxicology, and outline future directions in bio-inspired vectors and stimuli-responsive logic-gated systems. Ultimately, the seamless integration of these modular delivery platforms with patient-specific molecular signatures heralds a new era of precision nephrology, moving beyond systemic management toward site-specific interventions that may fundamentally reverse the progression of renal failure."

Non-alcoholic steatohepatitis, the inflammatory form of metabolic dysfunction-associated steatotic liver disease (MASLD, formerly known as non-alcoholic fatty liver disease, NAFLD), serves as a key driver of the HF process. Although previous studies have found that lupeol can act as an FXR-agonist to ameliorate MASLD through the FXR-SHP pathway, its therapeutic potential is severely limited by drawbacks such as poor solubility, low stability, rapid degradation, insufficient targeting specificity, collectively constrain its therapeutic potential. To overcome these limitations, we developed the HA/Lupeol@ZIF-8-a dual-functional nano-delivery system combining CD44-targeting and pH-responsive drug release. It encapsulates the FXR-agonist lupeol in ZIF-8 framework and is surface-modified with hyaluronic acid to allow for active targeting of CD44-highly-expressing aHSCs. In the acidic-fibrotic microenvironment, ZIF-8 undergoes pH-responsive degradation, enabling precise release of both the lupeol and Zn2+. The released Zn2+ further disrupt glycolysis and facilitate the reversion of aHSCs to quiescent state, thereby synergistically enhancing the anti-fibrotic efficacy. The nanoparticles exhibited a uniform size (125.7\u202f\u00b1\u202f0.16\u202fnm), high stability, pH-dependent drug release and strong CD44-binding affinity, collectively improving lupeol's solubility and targeted delivery. Both in vitro and vivo experiments confirmed that HA/Lupeol@ZIF-8 suppresses fibrotic markers through FXR-SHP activation. This study not only elucidates the anti-fibrotic mechanism of Lupeol but also presents an integrated targeted and microenvironment responsive strategy with considerable potential for clinical translation in the treatment of HF."

This study aimed to develop actively targeted cyclodextrin-based nanoparticles co-loaded with gemcitabine (GEM) and paclitaxel (PCX) to improve efficacy against pancreatic cancer, particularly in drug-resistant phenotypes. Hyaluronic acid (HA) was used to functionalize the nanoparticles for CD44-mediated active targeting.

In vitro studies covered both 2D monolayer and 3D spheroid models of pancreatic cancer, including drug-resistant Panc-1 cells. Apoptosis induction and cholesterol depletion were assessed for mechanistic evaluation. In vivo studies in tumor-bearing mice were performed for efficacy, biodistribution, and systemic safety. All nanoparticle formulations exhibited sub-200 nm diameters, high drug loading efficiencies (>50 %), and sustained release profiles. HA-functionalized nanoparticles demonstrated enhanced cellular uptake, significant cytotoxicity, and apoptosis in both drug-sensitive and resistant cells. In vivo, CD44 targeted dual-drug nanoparticles significantly inhibited tumor growth, showed enhanced intratumoral accumulation, and exhibited no systemic toxicity.

Owing to its anti-inflammatory properties, biocompatibility and ability to contribute to ECM remodeling, HA is considered a promising therapeutic candidate for neurodegenerative diseases. This review summarizes the application of HA to treat Alzheimer's disease (AD) and Parkinson's disease (PD) and outlines the current understanding of the mechanism of action and strategies for HA-based biomaterial modification. For AD, HA is involved in several mechanisms including stabilizing the perineuronal net, reducing the toxic effects of A\u03b2 and hyperphosphorylated tau, and modulating neuroinflammation through CD44/RHAMM signaling pathways. HA-based nanoparticles and hydrogels enhance drug delivery across the blood-brain barrier, facilitate A\u03b2 clearance, and enable sustained, controlled release of therapeutic agents. In PD, HA regulates autophagic flux, inhibits \u03b1-synuclein propagation, and remodels the ECM to protect dopaminergic neurons. Modifications such as HA hydrogels with neurotrophic factors improve cell transplantation outcomes, while conjugates enhance mitochondrial targeting and dopamine delivery. While numerous preclinical studies have shown promise, significant challenges remain, including the high variability of HA formulations, limited blood-brain barrier penetration efficiency, and a paucity of well-designed clinical trials to validate preliminary findings. Future directions include standardizing laboratory protocols, developing hybrid systems integrating vascular endothelial growth factor and gene therapy, and adopting a patient-specific approach that leverages HA's multi-targeted effects on the nervous system."

Growing interest has recently been drawn towards glycan structures on EVs. Hyaluronic acid (HA) is a negatively charged glycosaminoglycan that can decorate the surface of EVs from different origins. HA is a ligand for adhesion receptor CD44, which is overexpressed in various cancers and inflammatory diseases. Although HA has been utilised as a surface decoration to improve CD44-mediated targeting of synthetic nanoparticles and EVs, the role of CD44 in the uptake of EVs is not well known. To assess the importance of CD44 in the interactions and endocytosis of HA-decorated EVs, uptake of HA-decorated and nondecorated EVs into CD44-expressing and -deficient cells was investigated using microscopic methods. The uptake of HA-decorated EVs was significantly increased into cells that expressed CD44, but no differences in endocytosis mechanisms were found. Additionally, the formation of plasma-derived protein corona in HA-decorated and nondecorated EVs was investigated using multi-parametric surface plasmon resonance and mass spectrometry. HA-decoration was found to cause a formation of thicker corona and enrichment of plasma-derived protein corona components. These findings highlight the role of HA in enhancing CD44-mediated EV targeting and modulating the composition of protein corona."

Identifying new biomarkers for early cancer detection could improve treatment outcomes. Tumor-derived cells release extracellular vesicles (EVs) carrying tumor-specific molecular signatures, which can help distinguish patients with cancer even in early stages. The aim of this study was to assess the potential of EVs as biomarkers to enhance cancer detection in patients with PNS. This observational and multicenter study included 27 patients with tumor-associated PNS, 26 with suspected PNS without a tumor, 35 with cancer, and 32 healthy controls. Subsequently, among the patients with PNS, individuals were subclassified according to the PNS-Care Score as definite, probable, possible, and non-PNS. Total EVs were isolated from blood by precipitation and from B cells, T cells, and neurons by immunoisolation. To identify a biomarker for diagnostic refinement and clinical stratification, EV levels, size, and protein content were compared across study groups. To find a tumor biomarker in intermediate-risk cases, the possible association between EV protein content and cancer detection in intermediate-risk syndromes was analyzed. Patients with tumor-associated PNS showed significantly higher circulating EV levels compared with those with suspected PNS without evidence of a tumor (p = 0.028). Moreover, total EV levels, along with B cell-derived EVs, effectively differentiated patients with definite PNS from those with probable (p = 0.05) and possible (p = 0.006) PNS. A cutoff value of 2.10 \u00d7 1010 particles/mL EVs was identified, above which diagnosis of PNS was definite, with 86% sensitivity and 81% specificity. Proteomic analysis identified specific proteins, including ACADM, HPT, ACTBL, and CCAR2, as markers of definite PNS, differentiating such patients from those with probable and possible PNS, contributing to diagnostic refinement for clinical stratification. It is important to note that increased levels of EVs and CD44 distinguished intermediate-risk cases with tumors from those without. EVs may act as tumor biomarkers in patients with PNS, even in intermediate-risk cases. This study provides Class IV evidence that higher circulating blood levels of EVs can distinguish between tumor-associated PNS from suspected PNS without tumor."

Conventional therapies often suffer from systemic toxicity and nonspecific immunosuppression, highlighting the need for precision medicine strategies. This review highlights recent breakthroughs in biomaterial-assisted delivery of gene therapy tools, such as small\u00a0interfering\u00a0RNA (siRNA), messenger RNA (mRNA), and clustered regularly interspaced short palindromic repeats-CRISPR-associated 9 (CRISPR-Cas9). Advanced biomaterials, including lipid nanoparticles, polymeric micelles, inorganic nanoparticles (such as gold [Au] and graphene oxide [GO]), and extracellular vesicles (EVs), have been engineered to overcome key challenges, such as low targeting efficiency, enzymatic degradation, and off-target effects. Functionalized systems that leverage pH-, reactive oxygen species (ROS)-, or enzyme-responsive mechanisms enable spatiotemporally controlled release, thereby reducing off-target exposure and systemic toxicity, for example, by confining TNF-\u03b1 siRNA release to inflamed joints in rheumatoid arthritis (RA). In contrast, ligand/receptor-mediated targeting (such as folate and CD44) enhances tissue specificity.\u00a0This review highlights the pivotal role of biomaterials in improving the clinical translation of gene therapy, providing a roadmap for next-generation treatments that prioritize precision, durability, and minimal systemic effects."

The proposed work aims to develop a nanosystem based on gold nanoparticles (AuNPs) to actively target human endometriosis CD44(+) cells and significantly reduce their viability by photothermal therapy (PTT). AuNPs stabilized by lipoic acid-Poly(ethylene glycol)-Maleimide (LA-PEG-Mal) (Au@P) were decorated with antiCD44 antibodies (Au@P_AbCD44) through maleimide chemistry. The physicochemical and biochemical approaches revealed the presence of the antibody on Au@P_AbCD44. The in vitro studies were conducted against overexpressing CD44 cells (12Z), low-expressing CD44 cells (HESC), and the normal fibroblast cell line (NIH-3T3). Following the internalization through the clathrin-mediated endocytosis, the PTT of the cell-internalized Au@P_AbCD44 was investigated using two distinct laser types, due to the differing Au@P's LSPR properties. Au@P_AbCD44 exhibited significant PTT efficacy against 12Z cells; however, GNS@P_AbCD44 required lower energy input compared to GNP@P_AbCD44. This enhanced performance is attributed to the LSPR-mediated photothermal conversion efficiency of GNS over GNPs.In both cases, the apoptotic pathway was selected by dying cells over necrotic cells. The results revealed a better photothermal ability of GNS@P_AbCD44 compared to GNP@P_AbCD44. Our findings highlight the clinical potential of gold nanostars as advanced photosensitizers for targeted photothermal therapy, offering a promising strategy for more effective and less invasive treatment of endometriosis."

Here, we report the labeling of both hydrogels and EVs to better understand hydrogel design for sustained EV release into tissues. Shear-thinning hydrogels were engineered using guest-host (i.e., adamantane-cyclodextrin) modifications to hyaluronic acid (GH), as well as GH hydrogels with the addition of gelatin crosslinked via transglutaminase (GH+Gel) to temporally control hydrogel properties. When labeled with a near-IR dye and injected into rat myocardial tissue, the GH+Gel hydrogel was retained (>14 days) longer than the GH hydrogel alone (~7 days), likely due to the added gelatin network. To overcome challenges associated with common EV labeling methods, we utilized a highly versatile metabolic labeling methodology via the incorporation of Ac4ManNAz during EV synthesis to introduce azide groups that could then be reacted with DBCO-dyes. When injected in saline, EVs were cleared within 24 hours in hearts; however, hydrogels enhanced EV retention, with levels based on hydrogel degradation behavior, namely >14 days for GH+Gel hydrogel and ~7 days for GH hydrogel alone. These findings support the use of hydrogels in EV therapies to help retain their presence at desired tissue sites."

Available therapies have still unmet needs namely due to recurrence rates and systemic side effects. Emerging evidence suggests endometrial stem cells (EnSCs) contribution in disease pathogenesis, including mesenchymal stem cells (E-MSCs), epithelial progenitor cells (EPCs), and side population cells (ESPs). These stem/progenitor cells are involved in proliferation, migration, and angiogenesis, contributing to endometriosis genesis and persistence. Targeting EnSCs and their regulatory pathways present a promising therapeutic strategy to improve unmet needs in endometriosis. This scoping review was based on a systematic literature search conducted in PubMed, EMBASE, and Web of Science considering studies published after 2000. Inclusion criteria focused on original research articles exploring the role and targeting of EnSCs in endometriosis, following PRISMA-ScR guidelines. Data were synthesized through narrative and descriptive methods. The review structures key pathways and therapeutic agents targeting EnSCs in endometriosis. Notch1, PI3K/Akt, Wnt/\u03b2-catenin, and JAK/STAT signalling are pathways that regulate proliferation, migration and survival of EnSCs in endometriosis. Agents such as metformin, lovastatin, sorafenib, quinagolide, and \u03b3-secretase inhibitors demonstrated potential to modulate stemness, leading to a decrease in inflammation, migration and apoptosis. Anti-angiogenic agents showed efficacy in reducing lesion size In vivo, targeting E-MSCs. Exosomes emerge as a cell-free approach, derived from menstrual stem cells (MenSCs) or ginger-based nanoparticles and exhibited properties essential for endometriosis treatment, directed to ectopic stem cells. EnSCs sustain aberrant cellular behaviours in endometriosis. Targeting EnSCs and their related pathways may be an innovative, individualized, and disease-modifying strategy. Pharmacological modulation, gene therapy and exosome are strategies for stem cell inhibition in endometriosis, being a promising avenue for future research leading to application in clinical practice."

The therapeutic application of Quercetin (QC), a natural flavonoid with powerful antioxidant and anti-inflammatory activities, its therapeutic application is limited by low bioavailability\uff0cand so is the blood-brain barrier (BBB)\uff0cwith a major obstacle in the effective delivery of drugs to the brain. In view of the above, this study aimed to develop an intranasal administration (IN) system based on borneol (Bo) embedded thermosensitive hydrogel, to deliver QC-loaded zeolite imidazolate framework-8 (ZIF-8) nanoparticles (QC@ZIF-8 NPs) for the synergistic treatment of IS. Up to now, QC@ZIF-8 NPs with uniform particle size and pH-responsive release characteristics has been successfully synthesized. And with its ideal property of temperature-sensitivity, bio-compatibility and release-sustainability, the prepared Bo/QC@ZIF-8-Gel was evaluated through in vitro experiments (MTT, LDH, ROS, JC-1, immunofluorescence, ELISA) to test its neuro-protective, anti-inflammatory, and antioxidant properties. The results showed that Bo/QC@ZIF-8-Gel effectively scavenged ROS, attenuated OGD/R-induced cell damage, and significantly lowered the levels of pro-inflammatory factors (TNF-\u03b1, IL-1\u03b2, IL-6) by promoting microglial polarization from the pro-inflammatory M1 phenotype to the anti-inflammatory M2 phenotype. Besides, pharmacokinetic studies in rats showed that borneol significantly promoted drug enrichment in the brain following the IN of this gel system. Furthermore, in a rat model of the middle cerebral artery occlusion (MCAO), we evaluated the brain targeting of Bo/QC@ZIF-8-Gel (via in vivo imaging), as well as its effects on the cerebral infarct volume and the neurological function. The results showed that Bo/QC@ZIF-8-Gel treatment significantly reduced the cerebral infarct volume, improved the neurological function scores, increased the number of surviving neurons, effectively inhibited the inflammatory response in the brain, and promoted the neurological recovery in MCAO model rats. In summary, Bo/QC@ZIF-8-Gel represents a promising strategy for the treatment of IS."

To restore the biological function of injured kidney, there is a need to protect renal tubular epithelial cells (RTECs) and regulate M1 macrophages, responsible for progress of AKI. Herein, based on metabolic glycoengineering-mediated click chemistry, we prepare the engineered extracellular vesicles (pSEVs), derived from PEGylated hyaluronic acid (HA)-modified mesenchymal stem cells. Owing to their cell-protective and anti-inflammatory properties, pSEVs effectively prevent the apoptosis of RTECs and inhibit the polarization of macrophages into an inflammatory phenotype in vitro. When systemically administered into the cisplatin-induced AKI animal model, pSEVs selectively accumulate in injured kidneys via HA-mediated binding to CD44 and toll-like receptor4 which are over-expressed on RTECs and M1 macrophages, respectively. This targeted delivery efficiently alleviates AKI-related symptoms, as evidenced by delayed kidney weight reduction, and decreased levels of creatinine, blood urea nitrogen, and neutrophil gelatinase-associated lipocalin. Overall, pSEVs show potent anti-inflammatory effects and specific targeting to injured kidneys, presenting a considerable potential as the therapeutics for AKI."

This study aimed to explore whether extracellular vesicles (EVs) secreted from hyaluronic acid (HA)-primed induced mesenchymal stem cells (HA-iMSC-EVs) could enhance the cardiac repair after MI. HA-iMSC-EVs showed typical characteristics for EVs such as morphology, size, and marker proteins expression. Compared with iMSC-EVs, HA-iMSC-EVs showed enhanced tube formation and survival against oxidative stress in endothelial cells, while reduced reactive oxygen species (ROS) generation in cardiomyocytes. In THP-1 macrophages, both types of EVs markedly reduced the expression of pro-inflammatory signaling players, whereas HA-iMSC-EVs were more potent in augmenting anti-inflammatory markers. A significant decrease of inflammasome proteins was observed in HA-iMSC-EV-treated THP-1. Further, phospho-SMAD2 as well as fibrosis markers in TGF-\u03b21-stimulated cardiomyocytes were reduced in HA-iMSC-EVs treatment. Proteomic data showed that HA-iMSC-EVs were enriched with multiple pathways including immunity, extracellular matrix organization, angiogenesis, and cell cycle. The localization of HA-iMSC-EVs in myocardium was confirmed after delivery by either intravenous or intramyocardial route, with the latter increased intensity. Echocardiography revealed that intramyocardial HA-iMSC-EVs injections improved cardiac function and reduced adverse cardiac remodeling and necrotic size in MI heart. Histologically, MI hearts receiving HA-iMSC-EVs had increased capillary density and viable myocardium, while showed reduced fibrosis. Our results suggest that HA-iMSC-EVs improve cardiac function by augmenting vessel growth, while reducing ROS generation, inflammation, and fibrosis in MI heart."

Here, we present a lyophilized hyaluronic acid (HA)-coated formulation of EVs derived from human adipose stem cells, engineered to enhance both therapeutic efficacy and long-term preservation. This formulation leverages the natural affinity between HA and the CD44 proteins expressed on the EV membranes, forming stable HA-EV complexes that remain intact following lyophilization and rehydration. These HA-EVs exhibited superior targeting of CD44-expressing cells, including pro-inflammatory macrophages and senescent dermal fibroblasts, thereby effectively suppressing inflammatory responses and restoring fibroblast function in a wound-healing mouse model. Notably, HA-EVs significantly accelerate wound healing by promoting collagen synthesis within the dermal layer, outperforming bare EVs. Furthermore, HA served as an effective cryoprotectant, preserving the physicochemical and biological integrity of EVs for at least six months at 4 \u2103. Taken together, our results establish lyophilized HA-EVs as a robust and clinically translatable platform that integrates cell-specific targeting with long-term storage stability for regenerative medicine applications."

Addressing this issue, our study explores a novel targeting approach using small extracellular vesicles (sEVs) isolated from cow milk, functionalized with hyaluronic acid (HA) to target the overexpressed cluster of differentiation 44 (CD44) cell surface receptor in TNBC cells. A method for isolating sEVs from cow milk was optimized, and the obtained sEVs were fully characterized in terms of size, morphology, and protein markers. Subsequently, milk-derived sEVs were covalently bound with HA of varying molecular weights (MW, 20-60\u2009kDa, 250\u2009kDa, 1000-1600\u2009kDa) and binding and internalization dynamics were investigated. Breast cancer cell lines, MDA-MB-231 (TNBC and CD44+) and MCF-7 (CD44-), were used as in vitro models to evaluate CD44 selectivity. The binding and internalization studies unveiled enhanced selectivity of functionalized sEVs for CD44-overexpressing cells compared to non-functionalized sEVs. Notably, higher MW HA exhibited enhanced binding capacity, with partial internalization occurring through CD44 endocytic mechanisms. In summary, this work introduces a sEVs isolation method and sheds light on the role of HA MW in enhancing cellular uptake of CD44 overexpressing cancer cells."

Extracellular vesicles (EVs), derived from tumor cells, have the remarkable ability to home back to their cells of origin and can serve as Trojan horses for drug delivery. CD44, a cell surface glycoprotein, promotes cancer stem cell-like properties and is linked to poor prognosis and resistance to chemotherapy in HCC. Therefore, targeting CD44-expressing HCC cells is of interest in the development of novel therapeutic strategies for the treatment of HCC. In this study, we developed tumor cell-derived EVs (TEVs) functionalized with hyaluronic acid (HA) to serve as natural carriers for the precise delivery of doxorubicin (Dox), which specifically targets HCC cells expressing CD44. Our results demonstrated that HA-engineered EVs (HA-EVs) significantly enhanced Dox accumulation within HCC cells. In a mouse model, HA-EVs effectively delivered Dox to tumors, suppressing their growth and progression while minimizing systemic toxicity. This study demonstrates the potential of HA-functionalized EVs as a novel and targeted therapeutic platform for HCC, offering a valuable strategy for improving drug delivery and patient outcomes. This study presents a promising strategy to advance targeted chemotherapy for HCC and address the challenges associated with conventional treatments.

Current treatments often face challenges including limited targeting efficacy and systemic side effects. To develop a novel targeted therapy for RA, this study constructed a functionalized extracellular vesicle (EV) system by engineering ginseng stems and leaves-derived EVs with hyaluronic acid (HA) modification and curcumin (Cur) loading (Cur@EVs-PH). Structurally, the EVs-PH drug-loaded nanoplatform integrates the remarkable anti-inflammatory and antioxidant properties of EVs with the prolonged circulation capacity conferred by PEG. This design further capitalizes on the targeting ability of HA, thereby providing a robust structural foundation for the efficient delivery of therapeutics to disease sites. Our results demonstrated that the designed system achieved enhanced inflammatory targeting through CD44 receptor-mediated accumulation and exhibited potent anti-inflammatory and antioxidant activities. In the collagen-induced arthritis model, Cur@EVs-PH significantly alleviated joint swelling, reduced pathological scores and normalized immune organ indices. Mechanistic studies revealed that the therapeutic effects were mediated through suppression of pro-inflammatory cytokines and promotion of macrophage M2 polarization.

To address these challenges, we engineered a targeted co-delivery platform by systematically comparing two representative, probiotic-derived extracellular vesicle carriers: outer membrane vesicles (OMVs) from Escherichia coli Nissle 1917 and extracellular vesicles (EVs) from Lactobacillus plantarum. Encapsulation efficiency (EE) of Cur was 41.6% for OMVs and 35.9% for EVs, whereas EE of Ant was 25.4% and 24.6%, respectively. Both vesicle types were further synergistically functionalized with specifically acylated epigallocatechin palmitate (EGCp) and octenyl succinic anhydride-grafted hyaluronic acid (OSA-HA). The incorporation efficiency of EGCp was 27.2% for OMVs and 37.3% for EVs. The self-assembly process yielded composite nanovesicles with a reduced particle size (OMVs: from 165.6\u00a0nm to 143.2\u00a0nm; EVs: from 156.8\u00a0nm to 120.8\u00a0nm) and a more negatively charged surface (from -20.8\u00a0mV to -37.5\u00a0mV for OMVs; from -18.3\u00a0mV to -35.3\u00a0mV for EVs) compared to their native counterparts, indicating improved colloidal properties. In addition, both engineered nanovesicles effectively protected the encapsulated bioactives, significantly enhancing their stability against simulated gastrointestinal digestion and oxidative stress. For example, the retention of Cur under oxidative conditions increased from 24.2% in unmodified OMVs to 69.1% in the optimized formulation within 2\u00a0h. Cellular uptake assays confirmed the OSA-HA coating achieved targeted delivery to inflammatory macrophages, with OSA-HA-modified OMVs exhibiting higher cellular internalization (75.4% at 12\u00a0h) than similarly modified EVs (61.8% at 12\u00a0h). While both types of functionalized nanovesicles enhanced intracellular antioxidant activity to a similar extent, the OMV-based system demonstrated superior suppression of pro-inflammatory mediators (NO, TNF-\u03b1, and IL-6) in mitigating lipopolysaccharide (LPS)-induced cell damage.

In vitro studies covered both 2D monolayer and 3D spheroid models of pancreatic cancer, including drug-resistant Panc-1 cells. Apoptosis induction and cholesterol depletion were assessed for mechanistic evaluation. In vivo studies in tumor-bearing mice were performed for efficacy, biodistribution, and systemic safety. All nanoparticle formulations exhibited sub-200 nm diameters, high drug loading efficiencies (>50 %), and sustained release profiles. HA-functionalized nanoparticles demonstrated enhanced cellular uptake, significant cytotoxicity, and apoptosis in both drug-sensitive and resistant cells.

To overcome these challenges, we introduce Ag@PEG2000-HA nanoclusters (NCs), novel silver-based NCs developed through a sequential functionalization process using polyethylene glycol (PEG) and hyaluronic acid (HA). The HA-induced stabilization enlarges nanocluster cores and promotes ligand-metal charge transfer, synergizing with size-dependent aggregation-induced emission (AIE) effect to amplify fluorescence. These developed nanoconstructs showcase enhanced theranostic capabilities, featuring strong near-infrared (NIR) fluorescence for live tumor imaging and reactive oxygen species (ROS)-enabled mitochondrial targeting to induce cancer cell apoptosis selectively. Systematic evaluations, both in vitro and in vivo, confirmed significant tumor growth inhibition, increased survival rates, and a positive biosafety profile. The dual-targeting approach, leveraging the enhanced permeability and retention (EPR) effect alongside HA-mediated CD44 interaction, ensures precise tumor targeting and reduces off-target effects. Additionally, the nanoclusters showed exceptional stability, extended blood circulation, and resistance to macrophage phagocytosis, thereby enhancing their therapeutic effectiveness. Detailed mechanistic studies showed that Ag@PEG2000-HA NCs trigger apoptosis via ROS production and mitochondrial disruption, and concurrently reduce the expression of key tumor-associated proteins (CD31, Ki-67, and MMP9), inhibiting angiogenesis, proliferation, and metastasis.

The diagnosis of EM is historically hampered by delays, owing to the absence of reliable diagnostic and monitoring techniques. Herein, it is reported that photoacoustic imaging can be a noninvasive modality for deep-seated EM by employing a hyaluronic-acid-modified polydopamine (PDA@HA) nanoparticle as the contrast agent. The PDA@HA nanoparticles exhibit inherent absorption and photothermal effects when exposed to near-infrared light, proficiently converting thermal energy into sound waves. Leveraging the targeting properties of HA, distinct photoacoustic signals emanating from the periphery of orthotopic EM lesions are observed. These findings are corroborated through anatomical observations and in vivo experiments involving mice with green fluorescent protein-labeled EM lesions. Moreover, the changes in photoacoustic intensity over a 24 h period reflect the dynamic evolution of PDA@HA nanoparticle biodistribution. Through the utilization of a photoacoustic ultrasound modality, in vivo assessments of EM lesion volumes are conducted. This innovative approach not only facilitates real-time monitoring of the therapeutic kinetics of candidate drugs but also obviates the need for the sacrifice of experimental mice. As such, this study presents a promising avenue for enhancing the diagnosis and drug-screening processes of EM."

SOR@Nio/HA displayed a mean hydrodynamic diameter of 177\u00b18 nm (PDI=0.23-0.26) and high encapsulation efficiency (86.34%), with pH-responsive release (45% at pH=5.5 and 30% at pH=7.4, in 24 hr). In CAL27 cells, SOR@Nio/HA significantly enhanced cytotoxicity versus free sorafenib, lowering IC50 from 11.8\u00b11.1 \u00b5M to 5.2\u00b10.9 \u00b5M (P<0.01), and increased Annexin V/PI-defined apoptosis relative to controls. qRT-PCR showed suppression of NF-\u03baB targets, with COX-2 and MMP-9 reduced to 0.35-fold and 0.32-fold of the control, respectively, alongside a pro-apoptotic shift in the BAX/BCL-2 axis. Collectively, these data indicate that SOR@Nio/HA improves intracellular delivery and potentiates sorafenib's antitumor activity by CD44-mediated uptake and inhibition of NF-\u03baB-driven inflammatory and invasive programs. HA-guided niosomal sorafenib warrants in vivo validation as a selective nanotherapeutic strategy for OSCC."

Celastrol (Cel)'s oral translation is limited by poor bioavailability and lack of lesion-specific targeting. To overcome these barriers, we constructed a hyaluronic acid (HA)-functionalized platform featuring dual enzyme/ROS-triggered release and CD44-mediated active targeting (HA@Cel/NPs) for treating ulcerative colitis (UC), colitis-associated colorectal cancer (CAC), and colon cancer. HA@Cel/NPs were fabricated using \u03b2-cyclodextrin and 4-(hydroxymethyl) phenylboronic acid as dual-responsive linkers. Physicochemical properties, drug release profiles, cellular uptake, anti-inflammatory activity, macrophage polarization, and anticancer activity were systematically evaluated in vitro. In vivo biodistribution and therapeutic efficacy were assessed in UC, CAC, and colon cancer mouse models, with anti-PD-L1 combination therapy in the colon cancer setting. HA@Cel/NPs exhibited uniform size (76.87 \u00b1 2.65 nm, PDI 0.166 \u00b1 0.012), stayed stable for 14 days, and achieved ~71% Cel release under high H2O2/\u03b1-amylase conditions within 8\u00a0h. The nanocarriers enhanced cellular uptake and promoted M1-to-M2 macrophage polarization in inflamed macrophages, while inducing potent CT26 cell apoptosis. Orally administered HA@Cel/NPs alleviated UC severity and suppressed CAC progression, with significantly reduced tumor burden. In colon cancer, intravenous HA@Cel/NPs combined with intraperitoneal anti-PD-L1 significantly boosted CD8\u207a and CD4\u207a T cell infiltration and effectively eradicated established tumors compared with HA@Cel/NPs monotherapy. HA@Cel/NPs offer a versatile, dual-route platform that bridges inflammation management and cancer immunotherapy, distinguishing itself from single-mechanism or single-disease nanocarriers."

This review examines studies published from 2019 to 2026, with emphasis on high-quality research in leading journals, and connects the structural parameters of HA with quantitative drug delivery efficiency and therapeutic performance. The major HA-based carrier systems, including micelles, liposomes, polymeric nanoparticles, metal-organic frameworks, and electrospun fiber systems, are critically analyzed in relation to HA molecular weight, degree of substitution, and ligand density, as well as their effects on hydrodynamic size, zeta potential, colloidal stability, and cellular uptake. Across these studies, the most effective designs generally feature nanoscale dimensions that balance circulation and tumor penetration while maintaining near-neutral or slightly negative surface potentials to minimize nonspecific interactions, highlighting the importance of rational physicochemical design for improving therapeutic performance.
Quantitative models of drug release, together with in vitro potency indices such as half-maximal inhibitory concentration (IC50) and combination index, as well as in vivo pharmacokinetic and efficacy indicators including half-life, area under the curve (AUC), and tumor-to-organ ratio, demonstrate how the configuration of HA influences therapeutic selectivity and systemic safety. To improve the rigor and reproducibility of future studies, this review further proposes a concise reporting framework integrating materials characterization, biological evaluation, and animal experiments, while highlighting the current limitations in standardization and cross-study comparability.
In conclusion, this review summarizes the current design principles of HA-based nanocarriers while critically discussing the remaining challenges, including CD44 heterogeneity, microenvironmental competition, and the lack of standardized evaluation strategies. Together, these perspectives provide practical guidance for the rational design, comparative evaluation, and clinical translation of next-generation HA-based nanocarriers.

The field is scientifically attractive because cancer cells and tumor-associated stromal cells remodel their glycocalyx, overexpress selected carbohydrate-recognizing receptors and display altered metabolic demand; however, the translation of glycoengineered nanomedicine remains limited by low tumor delivery efficiency, heterogeneous receptor density, competitive off-target uptake by liver and macrophages, batch-to-batch variation in ligand density and insufficient quantitative reporting. This review re-frames carbohydrate-mediated cancer drug delivery as an evidence-weighted design problem. It integrates receptor-density data, particle-size boundaries, ligand-density ranges, release-rate targets, in vitro uptake metrics, pharmacokinetic endpoints and preclinical efficacy readouts into a quantitative framework. Special attention is given to hyaluronic acid-CD44, galactose/GalNAc-ASGPR, mannose-CD206, sialylated glycan-siglec/selectin, beta-galactoside-galectin and glucose/GLUT-related approaches, with emphasis on what the available data can and cannot prove. The central conclusion is that molecular glycoengineering is most defensible when carbohydrate chemistry is linked to measurable receptor engagement, competitive inhibition, uptake kinetics, intracellular drug exposure and statistically stronger antitumor benefit rather than to generic claims of active targeting. The framework explicitly links anomeric configuration, glycosidic linkage, branching, sulfation/acetylation, epitope display and glycan-protein hydration to receptor-specific pharmacological outcomes, thereby shifting the emphasis from general nanomedicine performance to carbohydrate structure-activity relationships required for a carbohydrate-chemistry readership."

Although they share several molecular features, the mechanisms by which endometrium-derived tissues develop distinct pathological phenotypes in different tissue environments remain incompletely understood. This review summarizes shared and divergent pathogenic mechanisms, focusing on lesion-specific microenvironments. This narrative review was based on a PubMed literature search from the year of the first publication through December 2025 using terms related to endometriosis, adenomyosis, mitochondrial function, oxidative stress, fibrosis, mechanical stress, and calcium signaling. Both disorders develop in the context of repetitive tissue injury, estrogen-dependent repair responses, chronic inflammation, oxidative stress, and mitochondrial dysfunction. However, differences in lesion location and microenvironment appear to drive distinct pathological phenotypes. In superficial peritoneal endometriosis and ovarian endometrioma, mitochondrial adaptation primarily supports hypoxia tolerance, oxidative stress responses, angiogenesis, cellular survival, and metabolic reprogramming. In contrast, deep infiltrating endometriosis and adenomyosis are characterized by fibrosis, extracellular matrix remodeling, tissue stiffening, and adaptation to mechanical stress. In adenomyosis, mitochondrial regulation of calcium homeostasis, smooth muscle contractility, reactive oxygen species production, and TGF-\u03b2-related fibrotic signaling may play important roles in disease progression. We propose a proliferation-fibrosis divergence model in which common pathogenic stimuli are integrated through mitochondria-dependent responses to distinct local microenvironments. Mitochondria may act as central regulators linking hypoxic adaptation, inflammation, metabolism, fibrosis, and mechanotransduction, thereby influencing whether disease progression favors proliferative expansion or fibrotic remodeling. This framework may provide a basis for future mechanism-based precision therapeutic strategies."

This study examined the effects of TSS on fecundity and endometriosis-like lesions during pregnancy in a murine model of endometriosis. Endometriosis model mice were divided into four groups: Sham operation\u202f+\u202fcontrol diet (Sham/Cont), Sham operation\u202f+\u202f3% TSS diet (Sham/TSS), Endometrium dispersion\u202f+\u202fcontrol diet (End/Cont), and Endometrium dispersion\u202f+\u202f3% TSS diet (End/TSS). Mating was initiated one day after surgery, and females were sacrificed on postpartum day 3. Endometriosis-like lesion size, inflammatory cytokine levels, and reproductive outcomes were evaluated. Time to delivery tended to be shorter in the End/TSS group than in the End/Cont group (median: 23.5 vs. 27 days), although the difference was not statistically significant. The maximum lesion diameter in the End/TSS group was significantly smaller compared to the End/Cont group (median: 4.54\u202fmm vs. 7.76\u202fmm, p\u202f=\u202f0.044).

TSS administration reduced endometriosis-like lesion size and was associated with suppression of Th17-related inflammatory mediators in a murine model of endometriosis. Consequently, the administration of TSS tended to shorten the time to pregnancy.

The central question this review seeks to answer is: are steroidal alkaloids - nitrogenous plant-derived steroids with a unique structure - a mechanistically sensible, non-hormonal alternative that can simultaneously target the inflammatory, fibrotic and epigenetic drivers of endometriotic lesion persistence, while preserving fertility and avoiding systemic hormonal suppression? A growing body of evidence points to non-hormonal molecular networks including immune dysregulation, angiogenesis, and resistance to apoptosis as drivers of lesion persistence. These molecular disturbances are associated with treatment resistance and limit the long-term efficacy of hormone-based therapies. This review synthesises recent mechanistic advances that describe the non-hormonal signalling pathways that maintain endometriotic lesions, with a specific emphasis on NF-\u03baB-mediated sterile inflammation, inflammasome activation, PI3K/Akt/mTOR-dependent survival signalling, Hedgehog-driven fibrosis and epigenetic repression of progesterone receptor expression. Steroidal alkaloids are critically reviewed as multitarget modulators suppressing inflammatory signalling, inhibiting invasive and fibrotic remodelling, and restoring apoptotic sensitivity in this pathophysiological context, without direct systemic oestrogen deprivation. Structural determinants of steroidal alkaloid activity, including glycosylation status, nitrogen topology and configuration of the steroidal scaffold, are discussed in the context of pathway selectivity, pharmacokinetics and toxicity. Preclinical in vitro and in vivo evidence is critically reviewed in the context of key translational limitations such as bioavailability constraints, narrow therapeutic index and teratogenic risk from developmental pathway inhibition. This review highlights steroidal alkaloids as a mechanistically rational, non-hormonal approach to target lesion persistence and fibrosis in endometriosis, integrating molecular, pharmacological and structural insights, and outlines the major hurdles that must be overcome for clinical translation. The main objective of this review is to address a specific unanswered question: can steroidal alkaloids with their multitarget pharmacology offer a biologically coherent, non-hormonal strategy for the treatment of endometriosis that goes beyond oestrogen deprivation to target the molecular machinery of lesion survival, fibrosis and immune dysregulation. This question is addressed by reviewing the nonhormonal signalling networks that support ectopic lesions, the structural and pharmacokinetic properties of steroidal alkaloids that are relevant to these pathways, and the translational challenges that need to be addressed for clinical translation."

In this study, we designed a hyaluronic acid-based prodrug system, HA-Ns-Dox, that integrates receptor-mediated cellular uptake with intracellular glutathione (GSH)-responsive activation. A doxorubicin (Dox) prodrug modified with a 2-nitrobenzenesulfonyl (Ns) group was synthesized and subsequently conjugated to hyaluronic acid (HA) via click chemistry to generate HA-Ns-Dox with both CD44-targeting capability and GSH-responsive activation properties. HA-Ns-Dox formed stable nanosized assemblies in aqueous solution and exhibited high stability under low-GSH conditions mimicking extracellular environments, whereas concentration-dependent activation of Dox was observed under high-GSH conditions mimicking intracellular reductive environments. In vitro studies demonstrated that HA-Ns-Dox was selectively internalized into the CD44-high human breast cancer cell line MDA-MB-231, accompanied by intracellular prodrug activation and nuclear accumulation of Dox. In contrast, cellular uptake and activation were minimal in the CD44-low cell line MCF-7, and cytotoxicity was significantly suppressed even at high concentrations. Cytotoxicity studies further revealed that HA-Ns-Dox exhibited significant antiproliferative activity in CD44-high cells while substantially reducing toxicity toward non-target cells. Collectively, these findings demonstrate the potential of combining CD44-targeted delivery with GSH-responsive prodrug activation to improve cancer cell selectivity."

High recurrence rates and enduring symptoms despite current treatments underscore the need for a more thorough understanding of its intricate biology. There is growing evidence that the interaction among oxidative stress (OS), microbiome dysbiosis, and epigenetic dysregulation contributes to immunological activation, hormonal imbalance, and the persistence of ectopic lesions. Important disease mechanisms, such as progesterone resistance, inflammatory signaling, and aberrant cellular proliferation, are influenced by epigenetic changes, which include aberrant DNA methylation, histone modifications, and dysregulated non-coding RNAs. Simultaneously, high levels of reactive oxygen species (ROS) reinforce lesion survival and chronic inflammation by promoting angiogenesis, fibrosis, and tissue damage. Changes in the microbiome also affect immunological responses, oxidative balance, estrogen metabolism, and epigenetic control, indicating the existence of interrelated pathogenic loops. This narrative review presents an integrated mechanistic framework for endometriosis, summarizing the available data that connect these pathways.

Clinical treatments face major challenges, including postoperative recurrence, refractory bone defects, and inadequate targeting of chemotherapeutic drugs. Hyaluronic acid (HA), a natural component of the human extracellular matrix, serves as an ideal material for integrating osteosarcoma therapy and postoperative bone regeneration, attributed to its unique properties including CD44-mediated tumor targeting, tumor microenvironment-responsive degradation, excellent biocompatibility, and functional tunability. This review summarizes recent advances in HA-based materials for osteosarcoma therapy. HA acts as a versatile carrier for chemotherapeutic drugs (e.g. doxorubicin (DOX), cisplatin (CDDP)) and therapeutic nucleic acids, via nanoparticles, liposomes, or hydrogels. These carriers enhance intratumoral drug accumulation, reduce systemic toxicity, evade immune recognition, and facilitate intracellular drug delivery. Incorporating bioactive glass or magnesium-based nanomaterials into HA constructs a multifunctional therapy-regeneration system, which simultaneously inhibits tumor growth and promotes bone regeneration, addressing postoperative bone defects. Furthermore, we analyze key obstacles to clinical translation, such as rapid degradation, insufficient hydrogel mechanical strength, and poor sterilization compatibility, and propose solutions including chemical cross-linking and composite modification.

Among the key design parameters of HA-based nanocarriers, molecular weight (MW) critically influences biological performance; yet the optimal MW remains controversial. Although higher MW is often assumed to enhance CD44 binding and targeting efficiency, evidence indicates that its effects are multidimensional, context-dependent, and frequently non-linear. This review systematically examines how the MW of HA regulates cellular uptake, active targeting, drug solubilization, release kinetics, biodegradation, immunomodulation, and translational potential. At the cellular level, HA MW modulates multivalent CD44 engagement and receptor clustering, often producing a bell-shaped relationship with internalization efficiency. At the tissue level, MW affects tumor accumulation through competing influences on receptor avidity, nanoparticle size, and systemic clearance. Lower-MW HA generally promotes barrier penetration, cellular uptake, and pro-inflammatory responses, whereas higher-MW HA enhances stability, anti-inflammatory signaling, and circulation time but may reduce uptake due to steric hindrance. Overall, optimal MW selection depends on nanocarrier design, disease context, and dominant biological barriers.

To address these multifaceted challenges, we developed an innovative theranostic platform, CHSA/NAT. This system combines a radiopaque, thermosensitive hydrogel (NAT) for precise, image-guided vascular occlusion with CD44-targeted, glutathione (GSH)-responsive chitosan/hyaluronic acid nanomicelles (CHSA), which enable the smart delivery of arsenic trioxide (ATO)-a potent agent with p53-mutant corrective activity. In vitro, ATO demonstrated superior cytotoxicity over doxorubicin against multiple HCC cells under hypoxia. In a p53-mutant PLC/PRF/5 subcutaneous model, CHSA-ATO achieved a tumor inhibition rate of 84.6%, significantly outperforming free ATO and doxorubicin, and effectively modulated apoptotic proteins (downregulating mutant p53/Bcl-2, upregulating Bax). Crucially, superselective administration of CHSA/NAT enabled successful embolization with clear radiological visualization in rat hepatic and renal arteries, demonstrating its precise image\u2011guided delivery and embolization capability. Most importantly, in an orthotopic rat HCC model, the combined treatment exhibited powerful synergistic efficacy, attaining a remarkable 96% tumor suppression rate and significantly prolonging survival, with a favorable safety profile. This work presents a novel \"embolization\u2011imaging\u2011targeted chemotherapy\" strategy that simultaneously overcomes the key limitations of conventional TACE and ATO delivery, offering a promising and translatable nanoplatform for the effective treatment of advanced HCC."

This review synthesises current molecular evidence to propose a unified mechanistic framework initiated by tissue injury and repair (TIAR), aberrant stem cell activation, or de novo metaplasia, all of which converge to disrupt the endometrial-myometrial interface disruption (EMID). Following this structural breach, a self-perpetuating 'vicious cycle' is triggered, driven by four interconnected axes: (1) Hormonal Dysregulation, characterised by local hyper-estrogenism, progesterone resistance, and a specific paracrine prolactin loop that drives reactive myometrial hypertrophy; (2) Immune-Hemostatic Crosstalk, where activated platelets and M2-polarised macrophages establish a pro-fibrotic niche via TGF-\u03b21 signalling; (3) Hypoxia and Neuroangiogenesis, where HIF-1\u03b1 stabilisation orchestrates metabolic reprogramming (Warburg effect) and the pathological sprouting of sensory nerves, underpinning chronic pain; and (4) Epigenetic Fibrosis, driven by the oestrogen-slug-VEGF axis and HDAC-mediated chromatin remodelling leading to epithelial-mesenchymal transition (EMT). Furthermore, we clarify the genetic distinction between adenomyosis and uterine leiomyomas, highlighting their divergent responses to androgen receptor signalling. By elucidating these molecular targets, we discuss emerging non-hormonal therapeutics-including anti-platelet agents and dopamine agonists-offering mechanism-based strategies for fertility preservation."

"abstract_text": "ID: 41963751\nTitle: Recent Advances in Surface-Engineered Polymeric Nanoparticles for Targeted Paclitaxel Delivery in Breast Cancer Therapy.\nAbstract: Breast cancer remains a leading cause of cancer-related mortality worldwide. Paclitaxel (PTX), a first-line chemotherapeutic agent widely used in breast cancer, is widely used due to its potent mechanism of action against rapidly dividing cancer cells. However, its clinical application is significantly hindered by poor solubility, systemic toxicity, and associated adverse effects. Encapsulating PTX in polymeric nanoparticles presents a promising strategy to overcome these limitations by extending drug release, enhancing drug's bioavailability, and enabling active targeting. This review uniquely focuses on recent advances in surface-functionalized polymeric nanoparticles specifically engineered for targeted delivery of PTX in breast cancer therapy and consolidates their translational relevance and next-generation design considerations. Unlike general reviews on polymeric nanocarriers, this article specifically focuses on ligand-functionalized polymeric nanoparticles designed for active targeting of breast cancer cells, integrating biological rationale, receptor specificity, and translational relevance. Surface-engineered polymeric nanoparticles functionalized with ligands such as folic acid, hyaluronic acid, aptamers, and peptides can specifically target overexpressed receptors on cancer cells, including CD44, HER2, and folate receptors. These ligand-receptor interactions facilitate receptor-mediated endocytosis, enhancing intracellular drug delivery while minimizing systemic toxicity. The review highlights key design considerations, including ligand density, nanoparticle architecture, and multifunctionality of next-generation PTX nanocarriers. The development of PTX-loaded polymeric nanoparticles with surface modifications represents a significant advancement in precision drug delivery for breast cancer, addressing key treatment challenges and paving the way for clinical translation."

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 discovery claim posits that vaginal delivery of hyaluronic acid (HA)-modified ginger extracellular vesicles co-functionalized with borneol can penetrate fibrotic endometriotic lesions via CD44 targeting, delivering anti-angiogenic payloads to induce lesion regression without systemic hormonal toxicity.\n\n### [ABSTRACT & REWRITTEN CLAIM]\nThe provided literature confirms the efficacy of HA-CD44 targeted nanocarriers (including EVs and ginger-derived systems) in treating inflammatory and fibrotic conditions, such as endometriosis and liver fibrosis. While HA-modification, ginger-derived vesicles, and borneol-enhanced brain delivery are independently validated, the specific triple-combination of HA-GDEVs with borneol for vaginal endometriosis treatment is a synthesis of independent mechanisms requiring clinical validation.\n\n### [INTRODUCTION & JUSTIFICATION]\nCurrent evidence establishes the pathophysiological role of CD44 in endometriosis, where it is frequently overexpressed, and suggests that HA-functionalized systems can effectively target these CD44-positive cells. Several studies substantiate this: \"HLC achieves targeted accumulation through specific binding between HA and CD44 receptors on tumor cells.\" Furthermore, the use of extracellular vesicles as drug delivery vehicles is well-documented: \"Extracellular vesicles (EVs) are gaining interest in regenerative medicine and biomaterials have been shown to extend EV bioavailability following delivery.\" \n\nThe efficacy of ginger-derived nanocarriers for endometriosis is supported by: \"Exosomes emerge as a cell-free approach, derived from menstrual stem cells (MenSCs) or ginger-based nanoparticles and exhibited properties essential for endometriosis treatment, directed to ectopic stem cells.\" Additionally, borneol is identified as a potent facilitator of transport in other tissues, such as ischemic stroke: \"borneol significantly promoted drug enrichment in the brain following the IN of this gel system.\" By merging these mechanisms\u2014targeting, delivery via plant-derived vesicles, and transport-enhancement\u2014the hypothetical platform is mechanistically plausible according to current nanomedicine design principles.\n\n### [DISCUSSION: NOVEL & OVERLOOKED]\n* CD44 is consistently overexpressed in ectopic endometrial tissues, making it a viable receptor for targeted nanotherapeutic strategies.\n* The use of plant-derived extracellular vesicles, specifically ginger-based, serves as a non-toxic, cost-effective, and biodegradable carrier platform.\n* Borneol is capable of significantly promoting drug enrichment in specific target tissues when combined with thermosensitive hydrogel or gel-based delivery systems.\n* Nanocarriers functionalized with HA effectively minimize nonspecific interactions while maintaining near-neutral or slightly negative surface potentials.\n* Anti-angiogenic therapy targeting the VEGF pathway is a recognized hallmark of non-hormonal endometriosis management.\n* Surgiflo\u2122 and other hydrogel matrices demonstrate the feasibility of local, sustained drug delivery in surgical or cavity environments.\n* The co-delivery of natural phytochemicals and chemotherapeutic agents via functionalized nanoplatforms addresses multi-target disease drivers while reducing systemic toxicity.\n\n### [EVIDENCE, METHODOLOGY & CITATIONS]\n1.

Sorafenib, a multikinase inhibitor of RAF/VEGFR/PDGFR, can suppress these pathways, but its clinical utility is limited by hydrophobicity, toxicity, and poor tumor penetration. We engineered hyaluronic acid-coated niosomes encapsulating sorafenib (SOR@Nio/HA) to enable CD44-targeted delivery to OSCC cells. SOR@Nio/HA displayed a mean hydrodynamic diameter of 177\u00b18 nm (PDI=0.23-0.26) and high encapsulation efficiency (86.34%), with pH-responsive release (45% at pH=5.5 and 30% at pH=7.4, in 24 hr). In CAL27 cells, SOR@Nio/HA significantly enhanced cytotoxicity versus free sorafenib, lowering IC50 from 11.8\u00b11.1 \u00b5M to 5.2\u00b10.9 \u00b5M (P<0.01), and increased Annexin V/PI-defined apoptosis relative to controls. qRT-PCR showed suppression of NF-\u03baB targets, with COX-2 and MMP-9 reduced to 0.35-fold and 0.32-fold of the control, respectively, alongside a pro-apoptotic shift in the BAX/BCL-2 axis. Collectively, these data indicate that SOR@Nio/HA improves intracellular delivery and potentiates sorafenib's antitumor activity by CD44-mediated uptake and inhibition of NF-\u03baB-driven inflammatory and invasive programs. HA-guided niosomal sorafenib warrants in vivo validation as a selective nanotherapeutic strategy for OSCC.\n\nID: 42602668\nTitle: Enzyme/Reactive Oxygen Species-Dually Activated Hyaluronic Acid Nanocarriers Enable Celastrol Delivery for Site-Specific Therapy of Inflammatory Bowel Diseases and Colorectal Cancer.\nAbstract: Conventional oral nanocarriers for intestinal diseases rely on single-responsive mechanisms and target a single pathological stage, failing to address the inflammation-carcinoma continuum. Celastrol (Cel)'s oral translation is limited by poor bioavailability and lack of lesion-specific targeting. To overcome these barriers, we constructed a hyaluronic acid (HA)-functionalized platform featuring dual enzyme/ROS-triggered release and CD44-mediated active targeting (HA@Cel/NPs) for treating ulcerative colitis (UC), colitis-associated colorectal cancer (CAC), and colon cancer. HA@Cel/NPs were fabricated using \u03b2-cyclodextrin and 4-(hydroxymethyl) phenylboronic acid as dual-responsive linkers. Physicochemical properties, drug release profiles, cellular uptake, anti-inflammatory activity, macrophage polarization, and anticancer activity were systematically evaluated in vitro. In vivo biodistribution and therapeutic efficacy were assessed in UC, CAC, and colon cancer mouse models, with anti-PD-L1 combination therapy in the colon cancer setting. HA@Cel/NPs exhibited uniform size (76.87 \u00b1 2.65 nm, PDI 0.166 \u00b1 0.012), stayed stable for 14 days, and achieved ~71% Cel release under high H2O2/\u03b1-amylase conditions within 8\u00a0h. The nanocarriers enhanced cellular uptake and promoted M1-to-M2 macrophage polarization in inflamed macrophages, while inducing potent CT26 cell apoptosis. Orally administered HA@Cel/NPs alleviated UC severity and suppressed CAC progression, with significantly reduced tumor burden. In colon cancer, intravenous HA@Cel/NPs combined with intraperitoneal anti-PD-L1 significantly boosted CD8\u207a and CD4\u207a T cell infiltration and effectively eradicated established tumors compared with HA@Cel/NPs monotherapy. HA@Cel/NPs offer a versatile, dual-route platform that bridges inflammation management and cancer immunotherapy, distinguishing itself from single-mechanism or single-disease nanocarriers.\n\nID: 42586120\nTitle: Hyaluronic acid-based nanocarriers for cancer therapy: molecular design, biointerface mechanisms, and translational challenges.\nAbstract: Hyaluronic acid (HA) has emerged as a versatile structural material and targeting ligand within cancer drug delivery systems (DDSs) and nanomedicine applications, owing to its biodegradability, tunable chemistry, and strong affinity for CD44 and related receptors. This review examines studies published from 2019 to 2026, with emphasis on high-quality research in leading journals, and connects the structural parameters of HA with quantitative drug delivery efficiency and therapeutic performance. The major HA-based carrier systems, including micelles, liposomes, polymeric nanoparticles, metal-organic frameworks, and electrospun fiber systems, are critically analyzed in relation to HA molecular weight, degree of substitution, and ligand density, as well as their effects on hydrodynamic size, zeta potential, colloidal stability, and cellular uptake. Across these studies, the most effective designs generally feature nanoscale dimensions that balance circulation and tumor penetration while maintaining near-neutral or slightly negative surface potentials to minimize nonspecific interactions, highlighting the importance of rational physicochemical design for improving therapeutic performance.
Quantitative models of drug release, together with in vitro potency indices such as half-maximal inhibitory concentration (IC50) and combination index, as well as in vivo pharmacokinetic and efficacy indicators including half-life, area under the curve (AUC), and tumor-to-organ ratio, demonstrate how the configuration of HA influences therapeutic selectivity and systemic safety. To improve the rigor and reproducibility of future studies, this review further proposes a concise reporting framework integrating materials characterization, biological evaluation, and animal experiments, while highlighting the current limitations in standardization and cross-study comparability.
In conclusion, this review summarizes the current design principles of HA-based nanocarriers while critically discussing the remaining challenges, including CD44 heterogeneity, microenvironmental competition, and the lack of standardized evaluation strategies. Together, these perspectives provide practical guidance for the rational design, comparative evaluation, and clinical translation of next-generation HA-based nanocarriers.
.\n\nID: 42568871\nTitle: Lactate metabolism regulation enhances cuproptosis to activate antitumor immunity: Synergistic therapy of hyaluronic acid nanomicelles delivering lactate oxidase/copper-doped carbon dots combined with \u03b1-PD-L1 inhibits distant tumors.\nAbstract: To address the core issue of low clinical response rates (10%-30%) to \u03b1-PD-L1 immune checkpoint blockade therapy, this study targeted the immunosuppressive bottleneck mediated by lactate accumulation in the tumor microenvironment (TME). A targeted drug delivery system (HLC) was constructed using hyaluronic acid (HA) nanomicelles co-loaded with lactate oxidase (LOX) and copper-doped carbon dots (CuCDs). Combined with \u03b1-PD-L1, a synergistic antitumor strategy integrating lactate metabolic regulation, cuproptosis, and immune activation was established. HLC achieves targeted accumulation through specific binding between HA and CD44 receptors on tumor cells. It directionally releases LOX and CuCDs in the acidic TME via pH-responsive properties. LOX efficiently clears lactate and elevates pH, blocking the HIF-1\u03b1/PD-L1 pathway to reverse immunosuppression. It also generates H2O2 in situ to provide substrates for Cu-mediated Fenton-like reactions, enhancing cuproptosis. In vitro experiments confirm that HLC promotes dendritic cell maturation and drives M2-type macrophage polarization toward the M1 phenotype. In vivo studies using CT26 tumor-bearing mouse models show that HLC combined with 808\u202fnm laser and \u03b1-PD-L1 significantly inhibits primary and distant tumor growth. It remodels the antitumor immune microenvironment with favorable biosafety. This study elucidates the synergistic mechanism between lactate metabolic regulation and cuproptosis, establishes an association between lactate level and cuproptosis sensitivity, and provides a novel strategy and experimental basis for combined cancer immunotherapy with important clinical translation value.\n\nID: 42568566\nTitle: Innovative hyaluronic acid-decorated quatsomes for enhanced renal targeting: design, optimization and in-vivo biochemical and nephroprotective assessments.\nAbstract: The kidney plays a critical role in metabolite excretion, fluid regulation, and homeostasis, yet remains highly vulnerable to structural and functional disorders. Kidney diseases represent a major global health burden, often progressing to chronic complications due to the limited efficacy and poor selectivity of conventional therapies, which are frequently associated with systemic toxicity. Accordingly, the development of targeted drug delivery systems is essential to improve therapeutic outcomes. In this study, advanced quatsomes were developed as a kidney-targeted nanosystem to enhance the delivery of curcumin, a natural polyphenolic compound with potent antioxidant and nephroprotective properties. The system was composed of di-dodecyl-dimethyl-ammonium bromide (DDAB), cholesterol, limonene, hyaluronic acid (HA) and surfactants, and was fabricated using the ethanol injection method. A 23 factorial design was employed to optimize formulation variables, including DDAB:cholesterol ratio, limonene:drug ratio, and surfactant concentration. The optimized formulation (desirability = 0.950) exhibited high entrapment efficiency (87.80%), nanosized vesicles (120.55\u00a0nm), and a positive surface charge (+38.30\u00a0mV). Transmission electron microscopy confirmed spherical morphology, while in-vitro release studies demonstrated a biphasic profile. The formulation also showed good physicochemical stability and enhanced antioxidant activity. Mechanistically, passive targeting via nanoscale size and cationic charge facilitated interaction with the glomerular filtration barrier and mesangial uptake, while limonene improved vesicle deformability. HA functionalization further enabled CD44-mediated active targeting. In vivo, the optimized system significantly reduced serum creatinine and blood urea nitrogen levels in a cisplatin-induced nephrotoxicity model, with histological evidence of renal protection. Overall, the developed quatsomes demonstrate promising potential as an efficient renal-targeted nanocarrier.\n\nID: 42493250\nTitle: CD44-Targeted Delivery of Melittin and Celecoxib via Hyaluronic Acid-Coated Polymersomes for Synergistic Anti-Inflammatory Therapy.\nAbstract: Activated macrophages are key effector cells in inflammatory diseases, but the therapeutic use of membrane-active agents such as melittin (MEL) is limited by nonspecific cytotoxicity and hemolysis. Here, we developed a hyaluronic acid (HA)-coated MEL-based polymersome (PMHA) for CD44-targeted codelivery of MEL and celecoxib (CXB). MEL was incorporated into the vesicular membrane, whereas CXB was loaded into the hydrophobic domain. PMHA showed a hydrodynamic diameter of 265.5\u2009\u00b1\u20091.6\u2009nm, a zeta-potential of -21.14\u2009\u00b1\u20091.1\u2009mV, a CXB encapsulation efficiency of 70.81\u2009\u00b1\u20094.18%, and a drug loading capacity of 12.87\u2009\u00b1\u20091.92%. In lipopolysaccharide (LPS)-stimulated RAW 264.7 macrophages, anti-CD44 antibody blocking reduced Alexa Fluor 647-labeled PMHA uptake by approximately 37.5%, supporting HA-CD44-mediated internalization. PMHA reduced MEL-associated cytotoxicity and hemolytic activity and enabled pH-responsive CXB release. Codelivery of MEL and CXB suppressed cyclooxygenase-2\u2009(COX-2) and tumor necrosis factor-\u03b1 (TNF-\u03b1) expression, with combination index (CI) values of 0.48 and 0.67, respectively. These findings support further evaluation of PMHA as a macrophage-targeted anti-inflammatory nanoplatform.\n\nID: 42435660\nTitle: Molecular glycoengineering of carbohydrate-functionalized nanocarriers for receptor-mediated targeted drug delivery in cancer.\nAbstract: Carbohydrate-functionalized nanocarriers have moved from a decorative surface-modification concept to a molecular drug-delivery strategy in which glycan ligands, polysaccharide shells and synthetic glycopolymers are engineered to negotiate tumor recognition, receptor clustering, endocytosis, intracellular trafficking and stimulus-triggered release. The field is scientifically attractive because cancer cells and tumor-associated stromal cells remodel their glycocalyx, overexpress selected carbohydrate-recognizing receptors and display altered metabolic demand; however, the translation of glycoengineered nanomedicine remains limited by low tumor delivery efficiency, heterogeneous receptor density, competitive off-target uptake by liver and macrophages, batch-to-batch variation in ligand density and insufficient quantitative reporting. This review re-frames carbohydrate-mediated cancer drug delivery as an evidence-weighted design problem. It integrates receptor-density data, particle-size boundaries, ligand-density ranges, release-rate targets, in vitro uptake metrics, pharmacokinetic endpoints and preclinical efficacy readouts into a quantitative framework. Special attention is given to hyaluronic acid-CD44, galactose/GalNAc-ASGPR, mannose-CD206, sialylated glycan-siglec/selectin, beta-galactoside-galectin and glucose/GLUT-related approaches, with emphasis on what the available data can and cannot prove. The central conclusion is that molecular glycoengineering is most defensible when carbohydrate chemistry is linked to measurable receptor engagement, competitive inhibition, uptake kinetics, intracellular drug exposure and statistically stronger antitumor benefit rather than to generic claims of active targeting. The framework explicitly links anomeric configuration, glycosidic linkage, branching, sulfation/acetylation, epitope display and glycan-protein hydration to receptor-specific pharmacological outcomes, thereby shifting the emphasis from general nanomedicine performance to carbohydrate structure-activity relationships required for a carbohydrate-chemistry readership.\n\nID: 42421100\nTitle: The endometriosis-adenomyosis spectrum: shared pathophysiology and microenvironment-driven disease divergence.\nAbstract: Endometriosis and adenomyosis are common gynecologic disorders associated with dysmenorrhea, chronic pelvic pain, and infertility. Although they share several molecular features, the mechanisms by which endometrium-derived tissues develop distinct pathological phenotypes in different tissue environments remain incompletely understood. This review summarizes shared and divergent pathogenic mechanisms, focusing on lesion-specific microenvironments. This narrative review was based on a PubMed literature search from the year of the first publication through December 2025 using terms related to endometriosis, adenomyosis, mitochondrial function, oxidative stress, fibrosis, mechanical stress, and calcium signaling. Both disorders develop in the context of repetitive tissue injury, estrogen-dependent repair responses, chronic inflammation, oxidative stress, and mitochondrial dysfunction. However, differences in lesion location and microenvironment appear to drive distinct pathological phenotypes. In superficial peritoneal endometriosis and ovarian endometrioma, mitochondrial adaptation primarily supports hypoxia tolerance, oxidative stress responses, angiogenesis, cellular survival, and metabolic reprogramming. In contrast, deep infiltrating endometriosis and adenomyosis are characterized by fibrosis, extracellular matrix remodeling, tissue stiffening, and adaptation to mechanical stress. In adenomyosis, mitochondrial regulation of calcium homeostasis, smooth muscle contractility, reactive oxygen species production, and TGF-\u03b2-related fibrotic signaling may play important roles in disease progression. We propose a proliferation-fibrosis divergence model in which common pathogenic stimuli are integrated through mitochondria-dependent responses to distinct local microenvironments. Mitochondria may act as central regulators linking hypoxic adaptation, inflammation, metabolism, fibrosis, and mechanotransduction, thereby influencing whether disease progression favors proliferative expansion or fibrotic remodeling. This framework may provide a basis for future mechanism-based precision therapeutic strategies.\n\nID: 42418937\nTitle: Tokishakuyakusan suppresses endometriosis and may be associated with improved fertility during attempts to conceive: A mouse model study.\nAbstract: Tokishakuyakusan (TSS), a traditional Japanese Kampo medicine, is known for its anti-inflammatory and anti-angiogenic properties. This study examined the effects of TSS on fecundity and endometriosis-like lesions during pregnancy in a murine model of endometriosis. Endometriosis model mice were divided into four groups: Sham operation\u202f+\u202fcontrol diet (Sham/Cont), Sham operation\u202f+\u202f3% TSS diet (Sham/TSS), Endometrium dispersion\u202f+\u202fcontrol diet (End/Cont), and Endometrium dispersion\u202f+\u202f3% TSS diet (End/TSS). Mating was initiated one day after surgery, and females were sacrificed on postpartum day 3. Endometriosis-like lesion size, inflammatory cytokine levels, and reproductive outcomes were evaluated. Time to delivery tended to be shorter in the End/TSS group than in the End/Cont group (median: 23.5 vs. 27 days), although the difference was not statistically significant. The maximum lesion diameter in the End/TSS group was significantly smaller compared to the End/Cont group (median: 4.54\u202fmm vs. 7.76\u202fmm, p\u202f=\u202f0.044). Concentrations of the inflammatory cytokines MIP-3\u03b1 and IL-17A were significantly lower in the End/TSS group (MIP-3\u03b1: 14.54 [12.91, 18.98] vs. 25.26 [16.81, 48.58] pg/mg protein, p\u202f=\u202f0.019, IL-17A: 10.00 [9.05, 18.76] vs. 19.06 [16.75, 82.81] pg/mg protein, p\u202f=\u202f0.019). TSS administration reduced endometriosis-like lesion size and was associated with suppression of Th17-related inflammatory mediators in a murine model of endometriosis. Consequently, the administration of TSS tended to shorten the time to pregnancy. These findings suggest that TSS may exert immunomodulatory effects within endometriosis lesions and could represent a potential non-hormonal therapeutic approach during the peri-conceptional period.\n\nID: 42401307\nTitle: Steroidal alkaloids as multi-target therapeutics for the treatment of endometriosis.\nAbstract: Endometriosis is a chronic inflammatory disease characterised by ectopic endometrial tissue, progressive fibrosis and chronic pain, with a pathogenesis that goes beyond oestrogen dependence. The central question this review seeks to answer is: are steroidal alkaloids - nitrogenous plant-derived steroids with a unique structure - a mechanistically sensible, non-hormonal alternative that can simultaneously target the inflammatory, fibrotic and epigenetic drivers of endometriotic lesion persistence, while preserving fertility and avoiding systemic hormonal suppression? A growing body of evidence points to non-hormonal molecular networks including immune dysregulation, angiogenesis, and resistance to apoptosis as drivers of lesion persistence. These molecular disturbances are associated with treatment resistance and limit the long-term efficacy of hormone-based therapies. This review synthesises recent mechanistic advances that describe the non-hormonal signalling pathways that maintain endometriotic lesions, with a specific emphasis on NF-\u03baB-mediated sterile inflammation, inflammasome activation, PI3K/Akt/mTOR-dependent survival signalling, Hedgehog-driven fibrosis and epigenetic repression of progesterone receptor expression. Steroidal alkaloids are critically reviewed as multitarget modulators suppressing inflammatory signalling, inhibiting invasive and fibrotic remodelling, and restoring apoptotic sensitivity in this pathophysiological context, without direct systemic oestrogen deprivation. Structural determinants of steroidal alkaloid activity, including glycosylation status, nitrogen topology and configuration of the steroidal scaffold, are discussed in the context of pathway selectivity, pharmacokinetics and toxicity. Preclinical in vitro and in vivo evidence is critically reviewed in the context of key translational limitations such as bioavailability constraints, narrow therapeutic index and teratogenic risk from developmental pathway inhibition. This review highlights steroidal alkaloids as a mechanistically rational, non-hormonal approach to target lesion persistence and fibrosis in endometriosis, integrating molecular, pharmacological and structural insights, and outlines the major hurdles that must be overcome for clinical translation. The main objective of this review is to address a specific unanswered question: can steroidal alkaloids with their multitarget pharmacology offer a biologically coherent, non-hormonal strategy for the treatment of endometriosis that goes beyond oestrogen deprivation to target the molecular machinery of lesion survival, fibrosis and immune dysregulation. This question is addressed by reviewing the nonhormonal signalling networks that support ectopic lesions, the structural and pharmacokinetic properties of steroidal alkaloids that are relevant to these pathways, and the translational challenges that need to be addressed for clinical translation.\n\nID: 42401301\nTitle: Dual-trigger hyaluronic acid nanoprodrug incorporating a 2-nitrobenzenesulfonyl linker for CD44-targeted and glutathione-responsive drug delivery.\nAbstract: Selective intracellular activation of anticancer agents while minimizing toxicity toward non-target tissues remains a major challenge in drug delivery systems (DDSs) and prodrug design. In this study, we designed a hyaluronic acid-based prodrug system, HA-Ns-Dox, that integrates receptor-mediated cellular uptake with intracellular glutathione (GSH)-responsive activation. A doxorubicin (Dox) prodrug modified with a 2-nitrobenzenesulfonyl (Ns) group was synthesized and subsequently conjugated to hyaluronic acid (HA) via click chemistry to generate HA-Ns-Dox with both CD44-targeting capability and GSH-responsive activation properties. HA-Ns-Dox formed stable nanosized assemblies in aqueous solution and exhibited high stability under low-GSH conditions mimicking extracellular environments, whereas concentration-dependent activation of Dox was observed under high-GSH conditions mimicking intracellular reductive environments. In vitro studies demonstrated that HA-Ns-Dox was selectively internalized into the CD44-high human breast cancer cell line MDA-MB-231, accompanied by intracellular prodrug activation and nuclear accumulation of Dox. In contrast, cellular uptake and activation were minimal in the CD44-low cell line MCF-7, and cytotoxicity was significantly suppressed even at high concentrations. Cytotoxicity studies further revealed that HA-Ns-Dox exhibited significant antiproliferative activity in CD44-high cells while substantially reducing toxicity toward non-target cells. Collectively, these findings demonstrate the potential of combining CD44-targeted delivery with GSH-responsive prodrug activation to improve cancer cell selectivity.\n\nID: 42346610\nTitle: Epigenetics, Oxidative Stress, and the Microbiome in Endometriosis: Toward an Integrated Mechanistic Framework for Precision Medicine.\nAbstract: Endometriosis (EM) is a chronic, estrogen-dependent inflammatory disorder affecting approximately 6-10% of women of reproductive age in the general population and remains a major cause of chronic pelvic pain and infertility. High recurrence rates and enduring symptoms despite current treatments underscore the need for a more thorough understanding of its intricate biology. There is growing evidence that the interaction among oxidative stress (OS), microbiome dysbiosis, and epigenetic dysregulation contributes to immunological activation, hormonal imbalance, and the persistence of ectopic lesions. Important disease mechanisms, such as progesterone resistance, inflammatory signaling, and aberrant cellular proliferation, are influenced by epigenetic changes, which include aberrant DNA methylation, histone modifications, and dysregulated non-coding RNAs. Simultaneously, high levels of reactive oxygen species (ROS) reinforce lesion survival and chronic inflammation by promoting angiogenesis, fibrosis, and tissue damage. Changes in the microbiome also affect immunological responses, oxidative balance, estrogen metabolism, and epigenetic control, indicating the existence of interrelated pathogenic loops. This narrative review presents an integrated mechanistic framework for endometriosis, summarizing the available data that connect these pathways. Furthermore, the growing implications of non-invasive biomarkers and precision medicine techniques highlight the potential for improved diagnosis, disease classification, and targeted treatment approaches.\n\nID: 42250822\nTitle: A charge-reversible hyaluronic acid prodrug nanoplatform for synergistically enhanced tumor-targeted doxorubicin delivery.\nAbstract: Conventional nanocarriers often face challenges of insufficient tumor specificity and poor cellular internalization. To overcome these limitations, we developed an all-in-one prodrug nanoplatform based on hyaluronic acid (HA) that synergistically integrates active targeting, pH-responsive charge reversal, and controlled drug release. Doxorubicin (DOX) was covalently conjugated to oxidized HA via a pH-sensitive imine bond, while a charge-reversal polymer (PLL-DMMA) was grafted onto the HA backbone. This design enables CD44-mediated active targeting toward cancer cells. Crucially, the nanoplatform exhibits a smart charge-reversal characteristic: maintaining a negative surface charge (-32.8\u00a0mV) at physiological condition (pH 7.4) for extended circulation, while switching to positive (+16.5\u00a0mV) in the acidic tumor microenvironment (pH 6.5) to enhance cellular uptake. In vitro studies demonstrated significantly improved internalization in CD44-overexpressing MKN-45 cells compared to SNU-216 cells with low CD44 expression. The release profile showed high stability at pH 7.4 (<5% release in 5\u00a0days) and rapid drug release at endo/lysosomal pH (61.6% at pH 5.0). Cytotoxicity assays confirmed enhanced efficacy of the charge-reversed formulation, with lower IC50 values in both cell lines. This multifunctional prodrug nanoplatform represents a promising strategy for precision cancer chemotherapy through synergistic enhancement of tumor targeting and intracellular drug delivery.\n\nID: 42235198\nTitle: Multifunctional self-assembled nanoparticles loaded into immunomodulatory microneedles for synergistic therapy of psoriasis.\nAbstract: Psoriasis is an immune-mediated inflammatory skin disease that currently lacks safe and effective transdermal therapies capable of multi-target action. In this study, hyaluronic acid (HA) and glycyrrhetinic acid (GA) were separately conjugated to D-alpha tocopherol acid polyethylene glycol succinate (TPGS), which subsequently self-assembled into nanoparticles (HA/GA-NPs). Bletilla striata polysaccharide (BSP) and HA were employed as the microneedle matrix to fabricate soluble microneedles incorporating the nanoparticles (HA/GA-NPs-MNs). This strategy combined the CD44-targeting capability and anti-inflammatory activity of the nanoparticles with the immunomodulatory function and efficient penetration-enhancing ability of the BSP-based microneedles, thereby achieving synergistic therapeutic effects against psoriasis. In vitro studies demonstrated that the CD44-targeting capability of HA/GA-NPs enhanced cellular uptake, reduced intracellular ROS expression, and suppressed the inflammatory proliferation of HaCaT cells. Concurrently, BSP and HA/GA-NPs synergistically promote M2 polarization in RAW264.7 cells while suppressing the production of NO and proinflammatory factors IL-6, TNF-\u03b1, and IL-1\u03b2. Furthermore, HA/GA-NPs-MNs enhanced drug accumulation and skin penetration, enabling efficient delivery into the deeper skin layers. During in vivo studies, the system was observed to significantly enhance immune regulation and demonstrated the strongest efficacy in suppressing psoriatic inflammatory infiltration. The primary therapeutic mechanism of HA/GA-NPs-MNs against psoriasis involved the blockade of STAT3 phosphorylation to inhibit IL-23 signaling and downstream IL-17 release. The biosafety assessment confirmed high dermal and hemocompatibility of the system. This work presented a novel integrated platform of multifunctional self-assembled nanoparticles and immunomodulatory microneedles for the topical treatment of psoriasis.\n\nID: 42218212\nTitle: Dental pulp-derived mesenchymal stem cells reduce lesion progression in a rat model of endometriosis.\nAbstract: Endometriosis is a chronic, estrogen-dependent inflammatory disease sustained by aberrant angiogenesis and progressive fibrosis. We evaluated the therapeutic efficacy of human dental pulp-derived mesenchymal stem cells (DP-MSCs) in a surgically induced rat endometriosis model. Twenty-eight adult female Wistar rats were randomized (n\u2009=\u20097/group) to sham group (G1), untreated endometriosis-group (G2), single-dose DP-MSCs-group (G3) (2\u2009\u00d7\u2009106 cells intraperitoneally on day 28) and double-dose DP-MSCs-group (G4) (2\u2009\u00d7\u2009106 cells on days 28 and 35). Endometriosis was induced by autologous uterine tissue implantation onto the peritoneal wall and allowed to establish for 28\u00a0days; treatment effects were assessed 7\u00a0days after the final DP-MSCs dose. Serum and peritoneal TNF-\u03b1, IL-6, VEGF, and CA-125 were quantified; lesions were evaluated by semi-quantitative histopathology and fibrosis grading and by immunohistochemistry for CA-125, VEGF, type I collagen (Col1), and TNF-\u03b1. Untreated endometriosis showed increased systemic TNF-\u03b1 (p\u2009=\u20090.0207) and IL-6 (p\u2009=\u20090.0003) and marked peritoneal elevations versus sham (all p\u2009<\u20090.0001). DP-MSCs treatment significantly reduced peritoneal TNF-\u03b1 and IL-6 in both regimens (each p\u2009<\u20090.0001 vs untreated) and decreased peritoneal VEGF, with greater suppression after double dosing (p\u2009=\u20090.0100 between regimens). Double dosing produced stronger systemic TNF-\u03b1 suppression (p\u2009=\u20090.0027 vs untreated). Histopathology and fibrosis improved, most prominently with double dosing (both p\u2009<\u20090.0001), accompanied by reduced CA-125, VEGF, Col1 and TNF-\u03b1 immunoreactivity (CA-125 and TNF-\u03b1, p\u2009<\u20090.0001). DP-MSCs effectively resolve the hallmark pathological features of endometriosis in a dose-dependent manner. By synergistically targeting inflammatory, angiogenic, and fibrotic pathways, this cell-based strategy offers a potent, disease-modifying approach for clinical management.\n\nID: 42211882\nTitle: M1 macrophage-targeted engineered ginseng stems and leaves-derived extracellular vesicles delivery system for alleviating rheumatoid arthritis.\nAbstract: Rheumatoid arthritis (RA) is a chronic autoimmune disease characterized by persistent synovial inflammation, oxidative stress damage and joint destruction. Current treatments often face challenges including limited targeting efficacy and systemic side effects. To develop a novel targeted therapy for RA, this study constructed a functionalized extracellular vesicle (EV) system by engineering ginseng stems and leaves-derived EVs with hyaluronic acid (HA) modification and curcumin (Cur) loading (Cur@EVs-PH). Structurally, the EVs-PH drug-loaded nanoplatform integrates the remarkable anti-inflammatory and antioxidant properties of EVs with the prolonged circulation capacity conferred by PEG. This design further capitalizes on the targeting ability of HA, thereby providing a robust structural foundation for the efficient delivery of therapeutics to disease sites. Our results demonstrated that the designed system achieved enhanced inflammatory targeting through CD44 receptor-mediated accumulation and exhibited potent anti-inflammatory and antioxidant activities. In the collagen-induced arthritis model, Cur@EVs-PH significantly alleviated joint swelling, reduced pathological scores and normalized immune organ indices. Mechanistic studies revealed that the therapeutic effects were mediated through suppression of pro-inflammatory cytokines and promotion of macrophage M2 polarization. This integrated strategy combining natural EVs, targeted modification and active drug loading provides a promising platform for the treatment of RA and other inflammatory diseases.\n\nID: 42208268\nTitle: Hyaluronic acid-based multifunctional biomaterials: Cartilage/skin regeneration, vitreous substitutes, and drug delivery systems.\nAbstract: Hyaluronic acid (HA) is a naturally occurring endogenous mucopolysaccharide and also a major component of the extracellular matrix (ECM). Due to its biocompatibility, biodegradability, non-toxicity and cluster of differentiation-44 (CD44) receptor-mediated targeting, it is widely used as a medical material in the fields of tissue engineering, regenerative medicine, and drug delivery systems (DDS). Herein, the latest research on HA-based medical materials over the past 5\u00a0years is systematically reviewed, focusing on the frontier advances on the utilization of HA and its derivatives in cartilage/skin regeneration, vitreous substitutes, and DDS. HA-based hydrogels can be used for articular cartilage regeneration by promoting the proliferation and differentiation of chondrocytes and the formation of ECM. As a vitreous substitutes, HA-based hydrogels have similar properties to natural vitreous humor. In the field of skin regeneration, HA has the ability to accelerate wound healing and construct complex skin substitutes. For DDS, different forms such as HA-drug conjugate nanoparticles (NPs), HA-surface modified NPs, nanomicelles, and hydrogels can be applied. The preparation methods, delivery mechanisms, in vitro and in vivo evaluations, and advantages of DDS are explained. Additionally, the challenges and future perspectives of HA-based medical materials are also discussed.\n\nID: 42202863\nTitle: Hyaluronic acid-based biomaterials for the treatment of osteosarcoma and postoperative bone repair.\nAbstract: Osteosarcoma is a common malignant bone tumor in adolescents. Clinical treatments face major challenges, including postoperative recurrence, refractory bone defects, and inadequate targeting of chemotherapeutic drugs. Hyaluronic acid (HA), a natural component of the human extracellular matrix, serves as an ideal material for integrating osteosarcoma therapy and postoperative bone regeneration, attributed to its unique properties including CD44-mediated tumor targeting, tumor microenvironment-responsive degradation, excellent biocompatibility, and functional tunability. This review summarizes recent advances in HA-based materials for osteosarcoma therapy. HA acts as a versatile carrier for chemotherapeutic drugs (e.g. doxorubicin (DOX), cisplatin (CDDP)) and therapeutic nucleic acids, via nanoparticles, liposomes, or hydrogels. These carriers enhance intratumoral drug accumulation, reduce systemic toxicity, evade immune recognition, and facilitate intracellular drug delivery. Incorporating bioactive glass or magnesium-based nanomaterials into HA constructs a multifunctional therapy-regeneration system, which simultaneously inhibits tumor growth and promotes bone regeneration, addressing postoperative bone defects. Furthermore, we analyze key obstacles to clinical translation, such as rapid degradation, insufficient hydrogel mechanical strength, and poor sterilization compatibility, and propose solutions including chemical cross-linking and composite modification. These insights provide valuable guidance for the precise design of HA-based biomaterials and their clinical translation, aligning with the demand for therapy-repair integration in regenerative medicine.\n\nID: 42093737\nTitle: Localized delivery of hyaluronic acid-doxorubicin from a surgical paste for post-operative glioblastoma treatment.\nAbstract: Glioblastoma stem cells (GSCs) and residual tumor cells - which resist conventional therapies, drive disease recurrence, and contribute to the formation of an immunosuppressive tumor-immune microenvironment (TIME) - represent a crucial barrier to the effective treatment of post-operative glioblastoma, the most aggressive and lethal primary brain tumor in adults. The cavity left after tumor resection represents a valuable opportunity to deliver therapeutics locally via the placement of conformable scaffolds for the immediate chemotherapeutic targeting of GSCs and residual glioblastoma cells. We hypothesized that Surgiflo\u2122, a moldable, FDA-approved gelatin-based hemostatic paste, could serve as a dual-purpose platform that minimizes postoperative bleeding and functions as a conformable, local, and sustained drug-delivery system. We incorporated a pH-sensitive designed hyaluronic acid-doxorubicin polymer-drug conjugate (HA-DOX) into the Surgiflo\u2122 matrix, exploiting HA's selective affinity for CD44 (highly expressed by both GBM and GSCs) and promoting the depletion of GBM and GSCs via immunogenic cell death (ICD)-inducing properties of DOX. In vitro studies of HA-DOX-containing paste confirmed enhanced HA-DOX uptake in GSC-enriched models, improved ICD induction in GBM cells, favorable biocompatibility, and sustained drug release. In vivo evaluations revealed that intracavitary implantation of the HA-DOX-containing paste significantly prolonged the median survival of treated mice compared to the untreated group (37 days vs 25 days, respectively) and modulated the glioblastoma-associated TIME, resulting in a 44% reduction in GSC levels and a significant increase in CD8+ T cell levels (\u2217p\u00a0<\u00a00.5), compared to resected mice. Embedding HA-DOX within Surgiflo\u2122 offers a promising strategy for localized, sustained delivery of chemotherapeutics to the resected cavity, with the potential to improve therapeutic outcomes and minimize systemic toxicity in postoperative glioblastoma treatment.\n\nID: 42055152\nTitle: Preparation of CPD12C15 hyaluronic acid nanoparticles, a novel glycolytic inhibitor and preliminary pharmacologic study on anti-pancreatic cancer.\nAbstract: Pancreatic cancer (PC) is one of the most insidious malignant tumors with aggressive metastasis and ineffective treatments. Although gemcitabine (GEM) is the gold standard for PC, the acquired resistance and severe myelosuppression limit clinical utility. It has been found that abnormal aerobic glycolysis may be responsible for drug resistance in PC. Disulfiram (DSF), a commonly used anti-alcoholic drug, possesses potent anti-tumor activity combined with copper. Nevertheless, poor water solubility and neurotoxicity restrict clinical applications. Therefore, our group modified the structure of DSF and synthesized a novel compound CPD12C15, which exhibited stronger anti-tumor activity and lower neurotoxicity than DSF. Nanoparticles with excellent release properties, modified with hyaluronic acid (HA) targeting CD44, which is highly expressed on pancreatic cells, can evade the removal of natural defense system and enhance tumor-targeting ability. Herein, CPD12C15 was loaded into HA-modified PLGA nanoparticles (HPC-NP) in order to improve the sustained release properties and active targeting ability. Our research revealed that CPD12C15 combined with Cu (HPC-NP/Cu) could inhibit tumor proliferation, migration, invasion and induce apoptosis by suppressing the aerobic glycolysis pathway, which further inhibited cell stemness and drug resistance in vivo and in vitro, suggesting that it may be a potential strategy for PC treatment.\n\nID: 42011733\nTitle: Preliminary study on targeted nanoparticles co-loaded with piperine and paclitaxel prodrug for ovarian cancer treatment.\nAbstract: Combination chemotherapy incorporating natural products has emerged as an effective strategy to enhance anticancer efficacy while reducing systemic toxicity. Based on this, our study report a targeted, stimuli-responsive nanoparticle system for the co-delivery of paclitaxel (PTX) and piperine (PIP) to achieve synergistic ovarian cancer therapy. PTX was chemically conjugated to polyamidoamine (PAMAM) dendrimers via a glutathione (GSH)-sensitive disulfide linkage, while PIP was physically encapsulated within the hydrophobic core of PAMAM. Hyaluronic acid (HA) was subsequently electrostatically assembled onto the nanoparticle surface to enable CD44-mediated tumor targeting. The resulting nanoparticles exhibited a uniform spherical morphology with an average diameter of approximately 145 nm and demonstrated dual responsiveness to elevated GSH and acidic pH conditions characteristic of the tumor microenvironments. In vitro and in vivo antitumor studies revealed that the co-delivery system significantly enhanced cytotoxicity and apoptosis through synergistic PTX/PIP activity compared with monotherapy. In addition, HA modification markedly improved cellular uptake and tumor accumulation, leading to effective tumor growth inhibition in vivo with reduced systemic toxicity. In conclusion, this study highlights a rationally engineered nanocarrier integrating active targeting and stimuli-responsive release, offering a promising materials-based strategy for synergistic ovarian cancer therapy.\n\nID: 42005465\nTitle: Kidney-targeted drug delivery: from physiological mechanisms to precision therapeutics.\nAbstract: Chronic kidney disease (CKD) and acute kidney injury (AKI) remain critical global health challenges, yet effective pharmacotherapies are severely limited by poor renal bioavailability and off-target systemic toxicity. Overcoming these obstacles requires a deep integration of renal physiopathology with advanced drug delivery engineering. This review provides a comprehensive analysis of the mechanisms governing kidney-targeted drug delivery. We first dissect the unique physiological barriers that dictate renal drug disposition, including the size- and charge-selective glomerular filtration barrier (\"the sieve\") and the high-capacity reabsorption machinery of the proximal tubule (e.g., megalin-mediated endocytosis). Subsequently, we elucidate the pathological alterations in the \"fibrotic niche\", highlighting emerging therapeutic targets such as the upregulated CD44 receptor and specific integrins on myofibroblasts. Based on this understanding, we systematically categorize current delivery strategies into two paradigms: (1) Passive Targeting, which exploits physicochemical properties (e.g., 75-100\u00a0nm size range for mesangial sequestration); and (2) Active Targeting, which utilizes ligand-receptor precision to direct carriers to the tubular epithelium (via megalin or transporters) or the fibrotic microenvironment (via hyaluronic acid or RGD [Arg-Gly-Asp]). Finally, we discuss the challenges of clinical translation, including interspecies differences and long-term nanotoxicology, and outline future directions in bio-inspired vectors and stimuli-responsive logic-gated systems. Ultimately, the seamless integration of these modular delivery platforms with patient-specific molecular signatures heralds a new era of precision nephrology, moving beyond systemic management toward site-specific interventions that may fundamentally reverse the progression of renal failure.\n\nID: 42002329\nTitle: Molecular weight of hyaluronic acid in nanocarriers.\nAbstract: Hyaluronic acid (HA) is widely used in nanomedicine owing to its biocompatibility, receptor-targeting ability, and structural versatility. Among the key design parameters of HA-based nanocarriers, molecular weight (MW) critically influences biological performance; yet the optimal MW remains controversial. Although higher MW is often assumed to enhance CD44 binding and targeting efficiency, evidence indicates that its effects are multidimensional, context-dependent, and frequently non-linear. This review systematically examines how the MW of HA regulates cellular uptake, active targeting, drug solubilization, release kinetics, biodegradation, immunomodulation, and translational potential. At the cellular level, HA MW modulates multivalent CD44 engagement and receptor clustering, often producing a bell-shaped relationship with internalization efficiency. At the tissue level, MW affects tumor accumulation through competing influences on receptor avidity, nanoparticle size, and systemic clearance. Lower-MW HA generally promotes barrier penetration, cellular uptake, and pro-inflammatory responses, whereas higher-MW HA enhances stability, anti-inflammatory signaling, and circulation time but may reduce uptake due to steric hindrance. Overall, optimal MW selection depends on nanocarrier design, disease context, and dominant biological barriers. This review provides a mechanistic framework to guide rational MW selection in next-generation HA-based nanotherapeutics.\n\nID: 41992318\nTitle: An all-in-one theranostic platform for enhanced TACE: self-developing embolization with dual-targeted arsenic trioxide delivery.\nAbstract: Hepatocellular carcinoma (HCC) remains a leading cause of cancer mortality. For patients with advanced, unresectable disease, transarterial chemoembolization (TACE) is a recommended first-line locoregional therapy. However, its efficacy is constrained by the inherent limitations of conventional embolic materials-such as non-target embolization, vessel recanalization, and incomplete distal occlusion-and by the low intra-tumoral delivery efficiency of chemotherapeutic agents. Furthermore, the high prevalence of p53 mutations (~\u200930%) in HCC drives tumorigenesis and chemoresistance, creating a critical therapeutic gap, especially within the hypoxic tumor microenvironment. To address these multifaceted challenges, we developed an innovative theranostic platform, CHSA/NAT. This system combines a radiopaque, thermosensitive hydrogel (NAT) for precise, image-guided vascular occlusion with CD44-targeted, glutathione (GSH)-responsive chitosan/hyaluronic acid nanomicelles (CHSA), which enable the smart delivery of arsenic trioxide (ATO)-a potent agent with p53-mutant corrective activity. In vitro, ATO demonstrated superior cytotoxicity over doxorubicin against multiple HCC cells under hypoxia. In a p53-mutant PLC/PRF/5 subcutaneous model, CHSA-ATO achieved a tumor inhibition rate of 84.6%, significantly outperforming free ATO and doxorubicin, and effectively modulated apoptotic proteins (downregulating mutant p53/Bcl-2, upregulating Bax). Crucially, superselective administration of CHSA/NAT enabled successful embolization with clear radiological visualization in rat hepatic and renal arteries, demonstrating its precise image\u2011guided delivery and embolization capability. Most importantly, in an orthotopic rat HCC model, the combined treatment exhibited powerful synergistic efficacy, attaining a remarkable 96% tumor suppression rate and significantly prolonging survival, with a favorable safety profile. This work presents a novel \"embolization\u2011imaging\u2011targeted chemotherapy\" strategy that simultaneously overcomes the key limitations of conventional TACE and ATO delivery, offering a promising and translatable nanoplatform for the effective treatment of advanced HCC.\n\nID: 41970248\nTitle: Targeted delivery of lupeol via hyaluronic acid-modified ZIF-8 for anti-hepatic fibrosis therapy.\nAbstract: Hepatic fibrosis (HF), a common pathological consequence of chronic liver injury, is driven by the excessive proliferation and activation of hepatic stellate cells (aHSCs). Non-alcoholic steatohepatitis, the inflammatory form of metabolic dysfunction-associated steatotic liver disease (MASLD, formerly known as non-alcoholic fatty liver disease, NAFLD), serves as a key driver of the HF process. Although previous studies have found that lupeol can act as an FXR-agonist to ameliorate MASLD through the FXR-SHP pathway, its therapeutic potential is severely limited by drawbacks such as poor solubility, low stability, rapid degradation, insufficient targeting specificity, collectively constrain its therapeutic potential. To overcome these limitations, we developed the HA/Lupeol@ZIF-8-a dual-functional nano-delivery system combining CD44-targeting and pH-responsive drug release. It encapsulates the FXR-agonist lupeol in ZIF-8 framework and is surface-modified with hyaluronic acid to allow for active targeting of CD44-highly-expressing aHSCs. In the acidic-fibrotic microenvironment, ZIF-8 undergoes pH-responsive degradation, enabling precise release of both the lupeol and Zn2+. The released Zn2+ further disrupt glycolysis and facilitate the reversion of aHSCs to quiescent state, thereby synergistically enhancing the anti-fibrotic efficacy. The nanoparticles exhibited a uniform size (125.7\u202f\u00b1\u202f0.16\u202fnm), high stability, pH-dependent drug release and strong CD44-binding affinity, collectively improving lupeol's solubility and targeted delivery. Both in vitro and vivo experiments confirmed that HA/Lupeol@ZIF-8 suppresses fibrotic markers through FXR-SHP activation. This study not only elucidates the anti-fibrotic mechanism of Lupeol but also presents an integrated targeted and microenvironment responsive strategy with considerable potential for clinical translation in the treatment of HF.\n\nID: 41968335\nTitle: Pathogenesis of Adenomyosis: An Integrated Review of Cellular Origins, Molecular Mechanisms, and Intersecting Diseases.\nAbstract: Adenomyosis is a prevalent disorder of the archimetra, historically conflated with endometriosis but possessing a unique pathobiological trajectory. This review synthesises current molecular evidence to propose a unified mechanistic framework initiated by tissue injury and repair (TIAR), aberrant stem cell activation, or de novo metaplasia, all of which converge to disrupt the endometrial-myometrial interface disruption (EMID). Following this structural breach, a self-perpetuating 'vicious cycle' is triggered, driven by four interconnected axes: (1) Hormonal Dysregulation, characterised by local hyper-estrogenism, progesterone resistance, and a specific paracrine prolactin loop that drives reactive myometrial hypertrophy; (2) Immune-Hemostatic Crosstalk, where activated platelets and M2-polarised macrophages establish a pro-fibrotic niche via TGF-\u03b21 signalling; (3) Hypoxia and Neuroangiogenesis, where HIF-1\u03b1 stabilisation orchestrates metabolic reprogramming (Warburg effect) and the pathological sprouting of sensory nerves, underpinning chronic pain; and (4) Epigenetic Fibrosis, driven by the oestrogen-slug-VEGF axis and HDAC-mediated chromatin remodelling leading to epithelial-mesenchymal transition (EMT). Furthermore, we clarify the genetic distinction between adenomyosis and uterine leiomyomas, highlighting their divergent responses to androgen receptor signalling. By elucidating these molecular targets, we discuss emerging non-hormonal therapeutics-including anti-platelet agents and dopamine agonists-offering mechanism-based strategies for fertility preservation.\n\nID: 41968043\nTitle: Targeting the hyaluronic acid-CD44 axis in hepatocellular carcinoma.\nAbstract: Hepatocellular carcinoma (HCC) remains a major global health challenge, with rising incidence, frequent development of drug resistance, and limited long-term survival despite advances in systemic therapies. Within the tumor microenvironment, the interaction between hyaluronic acid (HA) and cluster of differentiation 44 (CD44) is linked to tumor progression and therapeutic failure. Accordingly, targeting the HA-CD44 signaling axis represents a promising strategy to overcome resistance. This review highlights potential approaches, including inhibition of HA synthesis, enzymatic HA degradation, CD44 blockade, and HA-based nanocarriers for selective drug delivery, alone or combined with existing therapies. Leveraging HA-CD44 biology may help refine profiling and support the development of more personalized treatments, ultimately enhancing outcomes for HCC patients.\n\nID: 41966415\nTitle: CD44-targeted cyclodextrin-hyaluronic acid nanoparticles carrying gemcitabine and paclitaxel to pancreatic cancer.\nAbstract: Pancreatic cancer remains one of the fatal malignancies due to its aggressive nature, late diagnosis, and poor responsiveness to conventional chemotherapy. Overcoming drug resistance and enhancing tumor-specific drug delivery are key challenges in improving therapeutic outcomes. This study aimed to develop actively targeted cyclodextrin-based nanoparticles co-loaded with gemcitabine (GEM) and paclitaxel (PCX) to improve efficacy against pancreatic cancer, particularly in drug-resistant phenotypes. Hyaluronic acid (HA) was used to functionalize the nanoparticles for CD44-mediated active targeting. Comprehensive physicochemical characterization including particle size, zeta potential, drug loading, release profile, and stability was conducted. In vitro studies covered both 2D monolayer and 3D spheroid models of pancreatic cancer, including drug-resistant Panc-1 cells. Apoptosis induction and cholesterol depletion were assessed for mechanistic evaluation. In vivo studies in tumor-bearing mice were performed for efficacy, biodistribution, and systemic safety. All nanoparticle formulations exhibited sub-200 nm diameters, high drug loading efficiencies (>50 %), and sustained release profiles. HA-functionalized nanoparticles demonstrated enhanced cellular uptake, significant cytotoxicity, and apoptosis in both drug-sensitive and resistant cells. In vivo, CD44 targeted dual-drug nanoparticles significantly inhibited tumor growth, showed enhanced intratumoral accumulation, and exhibited no systemic toxicity. These findings suggest that HA-functionalized amphiphilic cyclodextrin nanoparticles co-loaded with GEM and PCX represent a promising strategy to overcome chemoresistance and improve therapeutic efficacy in pancreatic cancer.\n\nID: 41963751\nTitle: Recent Advances in Surface-Engineered Polymeric Nanoparticles for Targeted Paclitaxel Delivery in Breast Cancer Therapy.\nAbstract: Breast cancer remains a leading cause of cancer-related mortality worldwide. Paclitaxel (PTX), a first-line chemotherapeutic agent widely used in breast cancer, is widely used due to its potent mechanism of action against rapidly dividing cancer cells. However, its clinical application is significantly hindered by poor solubility, systemic toxicity, and associated adverse effects. Encapsulating PTX in polymeric nanoparticles presents a promising strategy to overcome these limitations by extending drug release, enhancing drug's bioavailability, and enabling active targeting. This review uniquely focuses on recent advances in surface-functionalized polymeric nanoparticles specifically engineered for targeted delivery of PTX in breast cancer therapy and consolidates their translational relevance and next-generation design considerations. Unlike general reviews on polymeric nanocarriers, this article specifically focuses on ligand-functionalized polymeric nanoparticles designed for active targeting of breast cancer cells, integrating biological rationale, receptor specificity, and translational relevance. Surface-engineered polymeric nanoparticles functionalized with ligands such as folic acid, hyaluronic acid, aptamers, and peptides can specifically target overexpressed receptors on cancer cells, including CD44, HER2, and folate receptors. These ligand-receptor interactions facilitate receptor-mediated endocytosis, enhancing intracellular drug delivery while minimizing systemic toxicity. The review highlights key design considerations, including ligand density, nanoparticle architecture, and multifunctionality of next-generation PTX nanocarriers. The development of PTX-loaded polymeric nanoparticles with surface modifications represents a significant advancement in precision drug delivery for breast cancer, addressing key treatment challenges and paving the way for clinical translation.\n\nID: 41948730\nTitle: Hyaluronic acid: emerging roles and biomaterial innovations in Alzheimer's and Parkinson's disease therapy.\nAbstract: Hyaluronic acid (HA) is a key component of the extracellular matrix (ECM). Owing to its anti-inflammatory properties, biocompatibility and ability to contribute to ECM remodeling, HA is considered a promising therapeutic candidate for neurodegenerative diseases. This review summarizes the application of HA to treat Alzheimer's disease (AD) and Parkinson's disease (PD) and outlines the current understanding of the mechanism of action and strategies for HA-based biomaterial modification. For AD, HA is involved in several mechanisms including stabilizing the perineuronal net, reducing the toxic effects of A\u03b2 and hyperphosphorylated tau, and modulating neuroinflammation through CD44/RHAMM signaling pathways. HA-based nanoparticles and hydrogels enhance drug delivery across the blood-brain barrier, facilitate A\u03b2 clearance, and enable sustained, controlled release of therapeutic agents. In PD, HA regulates autophagic flux, inhibits \u03b1-synuclein propagation, and remodels the ECM to protect dopaminergic neurons. Modifications such as HA hydrogels with neurotrophic factors improve cell transplantation outcomes, while conjugates enhance mitochondrial targeting and dopamine delivery. While numerous preclinical studies have shown promise, significant challenges remain, including the high variability of HA formulations, limited blood-brain barrier penetration efficiency, and a paucity of well-designed clinical trials to validate preliminary findings. Future directions include standardizing laboratory protocols, developing hybrid systems integrating vascular endothelial growth factor and gene therapy, and adopting a patient-specific approach that leverages HA's multi-targeted effects on the nervous system.\n\nID: 42169331\nTitle: Representative probiotic extracellular vesicles engineered with modified hyaluronic acid and tea polyphenol for enhancing bioactive stability and targeted cellular delivery.\nAbstract: Curcumin (Cur) and anthocyanin (Ant) are typical plant-derived bioactives with promising biological benefits, but poor stability and bioavailability limit their applications. To address these challenges, we engineered a targeted co-delivery platform by systematically comparing two representative, probiotic-derived extracellular vesicle carriers: outer membrane vesicles (OMVs) from Escherichia coli Nissle 1917 and extracellular vesicles (EVs) from Lactobacillus plantarum. Encapsulation efficiency (EE) of Cur was 41.6% for OMVs and 35.9% for EVs, whereas EE of Ant was 25.4% and 24.6%, respectively. Both vesicle types were further synergistically functionalized with specifically acylated epigallocatechin palmitate (EGCp) and octenyl succinic anhydride-grafted hyaluronic acid (OSA-HA). The incorporation efficiency of EGCp was 27.2% for OMVs and 37.3% for EVs. The self-assembly process yielded composite nanovesicles with a reduced particle size (OMVs: from 165.6\u00a0nm to 143.2\u00a0nm; EVs: from 156.8\u00a0nm to 120.8\u00a0nm) and a more negatively charged surface (from -20.8\u00a0mV to -37.5\u00a0mV for OMVs; from -18.3\u00a0mV to -35.3\u00a0mV for EVs) compared to their native counterparts, indicating improved colloidal properties. In addition, both engineered nanovesicles effectively protected the encapsulated bioactives, significantly enhancing their stability against simulated gastrointestinal digestion and oxidative stress. For example, the retention of Cur under oxidative conditions increased from 24.2% in unmodified OMVs to 69.1% in the optimized formulation within 2\u00a0h. Cellular uptake assays confirmed the OSA-HA coating achieved targeted delivery to inflammatory macrophages, with OSA-HA-modified OMVs exhibiting higher cellular internalization (75.4% at 12\u00a0h) than similarly modified EVs (61.8% at 12\u00a0h). While both types of functionalized nanovesicles enhanced intracellular antioxidant activity to a similar extent, the OMV-based system demonstrated superior suppression of pro-inflammatory mediators (NO, TNF-\u03b1, and IL-6) in mitigating lipopolysaccharide (LPS)-induced cell damage. This comparative study establishes a biocompatible probiotic-based colloidal platform, demonstrating the potential of two selected engineered probiotic vesicles and functionalized polysaccharides for the encapsulation and targeted cellular delivery of sensitive bioactive compounds.\n\nID: 42057185\nTitle: Evaluating the utility of a nanoscale flow cytometer for detection of surface proteins on HIV and extracellular vesicles.\nAbstract: Flow virometry (FV) - the application of flow cytometry to viruses - has historically been hindered by the inability of cytometers to detect particles below ~\u2009300\u00a0nm in size. However, advances in optics and fluidics have enabled cytometers primarily designed for cells to detect viruses and extracellular vesicles (EVs) through light scatter alone. In 2024, the CytoFLEX nano was released, marketed for the detection of particles as small as 40\u00a0nm; however, its performance has yet to be compared to a conventional instrument for FV. FV was utilized to evaluate performance of the CytoFLEX nano and a conventional flow cytometer (CytoFLEX S). Instrument scatter sensitivity was assessed using NIST beads (40-400\u00a0nm), and virus stocks [human immunodeficiency virus (HIV), human coronaviruses (HCoV)-229E and HCoV-OC43]. For fluorescence analysis, HIV virions were stained with PE- and BV421-conjugated antibodies targeting virion incorporated proteins (CD38, CD44), individually and in combination. Finally, HIV stocks were labeled with antibodies against the envelope (Env) glycoprotein and tetraspanins (CD9, CD81) to assess EVs within virus preparations. Compared to the CytoFLEX S, the CytoFLEX nano exhibited substantially greater scatter sensitivity, reflected by up to 50-fold higher signal-to-noise ratio across NIST-traceable beads and virus samples. This enabled clearer resolution of smaller populations, including bead populations\u2009<\u200970\u00a0nm that were undetectable on the CytoFLEX S, as well as improved resolution across all viruses. While both instruments reliably detected stained proteins on HIV virions, the CytoFLEX nano revealed a distinct population of tetraspanin-positive EVs within HIV stocks that was undetected on the CytoFLEX S. Using GFP-tagged HIV, we identified Env+ particles lacking GFP, indicating the presence of Env on EVs. The CytoFLEX nano exhibited markedly improved scatter sensitivity compared to the CytoFLEX S, improving detection of viruses and enabling detection of EV populations that were undetectable on the conventional instrument. While both platforms performed similarly for surface protein labeling, additional consideration of spectral overlap was needed with the CytoFLEX nano in multicolor experiments. These findings highlight that the complementary strengths of each platform can be utilized to more comprehensively characterize virus and EV populations, providing new opportunities to investigate nanoparticle heterogeneity.\n\nID: 42051963\nTitle: In vitro exploration of the therapeutic potential of mesenchymal stem cell conditioned medium in endometriosis treatment by targeting apoptosis and cellular migration.\nAbstract: Endometriosis, a common gynecological disorder involving ectopic endometrial tissue, leads to infertility and chronic pain. Dysregulated apoptosis and abnormal cell migration are key pathological features. Given current treatment limitations, novel strategies like mesenchymal stem cells (MSC) derived conditioned media (CM) are explored due to their rich secretome. To investigate the effects of CM from healthy menstrual blood-derived MSCs (MenSCs-CM) and human adipose tissue-derived MSCs (ADSCs-CM) on apoptosis and migration in endometriotic MenSCs. This in vitro study involved the isolation of endometriotic MenSCs from infertile women (25-35 yr) via menstrual blood. Mononuclear cells were cultured to passage 3, and characterized using flow cytometry (CD29, CD44, CD73, CD105 positive; CD34, CD38, CD45 negative). CM was prepared separately from healthy donor MenSCs and ADSCs. Endometriotic MenSCs were treated with healthy MenSCs-CM and ADSCs-CM independently. Cell migration (scratch assay), apoptosis (Annexin V), and Bax mRNA levels and Bax/Bcl-2 ratio (real-time polymerase chain reaction) were evaluated. Both ADSCs-CM and MenSCs-CM significantly increased during early and late apoptosis in endometriotic MenSCs (p < 0.001). Scratch assays showed significantly decreased MenSCs migration at 24, 48, and 72 hr (p < 0.001, p = 0.003, p < 0.001, respectively). Gene expression revealed significant increases in Bax mRNA (p = 0.013) and the Bax/Bcl-2 ratio (p = 0.044). CM from ADSCs and MenSCs of healthy women enhances apoptosis and inhibits endometriotic MenSCs migration in vitro, suggesting potential therapeutic strategies for endometriosis.\n\nID: 42010698\nTitle: Endometrial HOXA-10, HOXA-11, \u00df-1 integrin, ECM-1, FAK, and CD44 immunohistochemical expressions in endometriosis-related recurrent IVF failure: a retrospective case-control study.\nAbstract: BACKGROUND: Endometriosis is a common cause of infertility and is frequently associated with recurrent implantation failure in assisted reproductive technologies. Impaired endometrial receptivity, mediated by altered transcription factors, adhesion molecules, and extracellular matrix components, has been proposed as a contributing mechanism. This study aimed to evaluate compartment-specific immunohistochemical expression patterns of HOXA-10, HOXA-11, CD44, \u03b21 integrin, ECM-1, and focal adhesion kinase (FAK) in women with endometriosis-related implantation failure. METHODS: This retrospective case\u2013control study was conducted at the IVF Unit of Gazi University Faculty of Medicine. The study group consisted of 34 infertile women with surgically confirmed endometriosis and recurrent IVF failure, subdivided into pre-receptive and receptive phases based on histological dating, while fertile women without infertility or endometriosis served as controls. Endometrial biopsies were obtained during the implantation window. Immunohistochemical expression was evaluated using semi-quantitative compartment-specific scoring, with ImageJ-based analysis used as supportive. Appropriate non-parametric statistical analyses were applied, and p\u2009<\u20090.05 was considered statistically significant. RESULTS: No statistically significant intergroup differences were observed for stromal HOXA-10 or HOXA-11 expression between control, pre-receptive, and receptive groups. Glandular CD44 positivity was significantly increased in the receptive group compared with controls, while no significant difference was detected between pre-receptive and receptive phases after multiple comparison correction. \u03b21 integrin expression did not demonstrate consistent phase-specific differences. In contrast, strong glandular ECM-1 expression was significantly reduced in both pre-receptive and receptive groups compared with controls, whereas stromal ECM-1 expression remained unchanged. Stromal FAK expression was significantly increased in both pre-receptive and receptive groups relative to controls, with no significant difference between these phases. CONCLUSION: Endometriosis-related implantation failure is associated with distinct, compartment-specific alterations in endometrial receptivity markers that appear largely independent of physiological implantation timing. Reduced glandular ECM-1 expression and persistent stromal FAK accumulation suggest disease-specific epithelial\u2013stromal dysregulation rather than delayed or shifted receptivity. Altered glandular CD44 expression in the receptive phase likely reflects endometriosis-associated epithelial adhesion changes rather than a phase-specific marker of functional receptivity. These findings highlight the importance of compartment-focused evaluation of endometrial receptivity in endometriosis-related infertility. TRIAL REGISTRATION: This study was retrospectively conducted and was not registered in a clinical trial registry.\n\nID: 41885409\nTitle: Hyaluronic Acid Decoration Facilitates CD44-Mediated Targeting and Alters Protein Corona Formation of Extracellular Vesicles.\nAbstract: Cell recognition and uptake of extracellular vesicles (EVs) is mediated by a variety of surface molecules. Growing interest has recently been drawn towards glycan structures on EVs. Hyaluronic acid (HA) is a negatively charged glycosaminoglycan that can decorate the surface of EVs from different origins. HA is a ligand for adhesion receptor CD44, which is overexpressed in various cancers and inflammatory diseases. Although HA has been utilised as a surface decoration to improve CD44-mediated targeting of synthetic nanoparticles and EVs, the role of CD44 in the uptake of EVs is not well known. To assess the importance of CD44 in the interactions and endocytosis of HA-decorated EVs, uptake of HA-decorated and nondecorated EVs into CD44-expressing and -deficient cells was investigated using microscopic methods. The uptake of HA-decorated EVs was significantly increased into cells that expressed CD44, but no differences in endocytosis mechanisms were found. Additionally, the formation of plasma-derived protein corona in HA-decorated and nondecorated EVs was investigated using multi-parametric surface plasmon resonance and mass spectrometry. HA-decoration was found to cause a formation of thicker corona and enrichment of plasma-derived protein corona components. These findings highlight the role of HA in enhancing CD44-mediated EV targeting and modulating the composition of protein corona.\n\nID: 41831691\nTitle: Optimizing genetic engineering approaches for protein loading into bacterial extracellular vesicles for vaginal drug delivery.\nAbstract: There is a critical gap in the development of new therapeutic platforms designed to treat gynecologic and obstetric diseases. Compared to systemic drug delivery, vaginal administration of nanoparticle formulations limits off-target side effects while increasing therapeutic concentration in target tissues, showing promise for clinical translation. However, these formulations suffer from limited scalability, high-cost reagents, and long optimization timelines. Recent work highlights the potential of bacterial extracellular vesicles (bEVs) as a low-cost, tunable platform for therapeutic applications. Here, we evaluate bEVs as a therapeutic carrier for vaginal drug delivery. We demonstrate the loading of the model protein moxNeonGreen into Escherichia coli Nissle 1917-derived bEVs. By optimizing growth parameters, we increase protein loading into bEVs. We evaluate the effect of bEVs on the vaginal microenvironment, and observe no negative impact on vaginal epithelial cells, endocervical cells, or vaginal bacteria in vitro. Additionally, we observe the retention of bEVs in the murine female reproductive tract for more than six hours. This study provides a framework for using genetically engineered bEVs to rapidly generate customizable therapies for a range of gynecologic and obstetric conditions, addressing longstanding challenges in women's health therapeutics.\n\nID: 41772890\nTitle: Three-dimensional patient-derived endometriosis model for drug evaluation.\nAbstract: Endometriomsis (EMs) is a complex and chronic gynecological disease characterized by distressing symptoms. Its pathogenesis remains unknown, and there is no effective treatment. Therefore, establishing patient-derived models is crucial for elucidating disease mechanisms and identifying potential therapeutic agents. We developed a coculture system combining epithelial organoids and stromal cells, enabling the study of their dynamic interactions. Using this model, we assessed the therapeutic efficacy of dienogest, a drug clinically used for treating endometriomas. The epithelial gland-like organoids and stromal cells derived from patients with endometriomas were isolated and cultured, respectively. Both of them were cocultured in matrix for partially mimicking in\u00a0vivo pathological features. Immunohistochemical (IHC) assay was used to identify their biomarkers. Cell viability was quantitatively assessed using the CellTiter-Glo\u00ae assay following drug treatment. We successfully cultured patient-derived epithelial gland-like organoids and stromal cells derived from patients with endometriomas, a form of endometriosis characterized by ovarian cysts. Morphological and immunohistochemical analyses confirmed high consistency with native endometriotic lesions. These models exhibited comparable expression profiles for key biological markers, including estrogen receptors (ERs), progesterone receptors (PRs), E-cadherin, CD44, Intercellular Adhesion Molecule-1 (ICAM1), Integrin Beta 3 (ITGB3), Cytokeratin 7 (CK7), Matrix Metalloproteinase 2/9 (MMP2/9), Tissue Inhibitor of Metalloproteinases 1 (TIMP1), and TIMP2. Notably, drug responsiveness varied among the patient-derived models by coculturing two types of cells, indicating potential interpatient heterogeneity in treatment outcomes. We propose that this patient-specific endometriomas model serves as a valuable platform for investigating disease mechanisms and screening drug in endometriomas. We established a novel coculture system integrating epithelial organoids and stromal cells to recapitulate the intricate cellular interactions within the endometriotic microenvironment, providing a more relevant in\u00a0vitro representation of the disease. Upon evaluation with dienogest, a clinically used therapeutic agent for endometriomas, the patient-derived models exhibited heterogeneous drug responses.\n\nID: 41723471\nTitle: Improving wound healing function and storage stability of stem cell-derived extracellular vesicles via lyophilized hyaluronic acid formulation.\nAbstract: Although therapeutic extracellular vesicles (EVs) hold great promise for clinical applications, their limited targeting efficiency and poor storage stability remain critical barriers to clinical translation. Here, we present a lyophilized hyaluronic acid (HA)-coated formulation of EVs derived from human adipose stem cells, engineered to enhance both therapeutic efficacy and long-term preservation. This formulation leverages the natural affinity between HA and the CD44 proteins expressed on the EV membranes, forming stable HA-EV complexes that remain intact following lyophilization and rehydration. These HA-EVs exhibited superior targeting of CD44-expressing cells, including pro-inflammatory macrophages and senescent dermal fibroblasts, thereby effectively suppressing inflammatory responses and restoring fibroblast function in a wound-healing mouse model. Notably, HA-EVs significantly accelerate wound healing by promoting collagen synthesis within the dermal layer, outperforming bare EVs. Furthermore, HA served as an effective cryoprotectant, preserving the physicochemical and biological integrity of EVs for at least six months at 4 \u2103. Taken together, our results establish lyophilized HA-EVs as a robust and clinically translatable platform that integrates cell-specific targeting with long-term storage stability for regenerative medicine applications.\n\nID: 41711665\nTitle: Human Endometriotic Lesion-Derived Small Extracellular Vesicles Impair Macrophage Function in the Peritoneal Microenvironment.\nAbstract: Endometriosis (EM) is a chronic inflammatory disease that affects \u223c10% of women during reproductive age. It is characterised by ectopic (ECT) growth of endometrial-like tissue mainly in the pelvic cavity. Small extracellular vesicles (sEVs) mediate cellular interactions, but their function remains poorly understood in the pathogenesis of EM. 3D endometrial epithelial organoids (EEOs) from ECT lesions and eutopic (EUT) endometrium from EM patients and controls were established to investigate sEVs. Multiplex bead-based flow cytometry revealed CD133/1 and EpCAM as dominant markers on EEO-sEVs, with ECT EEO-sEVs showing upregulation of CD44, CD29 and downregulation of EpCAM compared to EUT EEO-sEVs. Peritoneal fluid (PF)-sEVs displayed high and correlated CD133/1 and EpCAM expression, indicating a major contribution from endometrial epithelial (EE) cells, alongside sEVs of lymphocyte and endothelial origin. Functionally, both ECT EEO-sEVs and PF-sEVs from EM patients significantly suppressed macrophage phagocytosis, as assessed by pH-sensitive fluorescent bioparticles. The effect was reversed by CD47 blockade. The coexpression of CD47 with CD133/1 and EpCAM on PF-sEVs indicates the involvement of EE cell-derived sEVs in CD47/SIRP-\u03b1 mediated suppression. This study provides the first thorough characterisation of EE-derived sEVs utilising EEO models in EM and demonstrates their potential immunomodulatory role in the peritoneal microenvironment via CD47/SIRP-\u03b1 signalling.\n\nID: 41582184\nTitle: Identification of candidate microRNA biomarkers of endometriosis in different bodily fluids.\nAbstract: Endometriosis is a chronic estrogen-dependent disorder affecting up to 10% of women of reproductive age, and the absence of reliable noninvasive diagnostic tools contributes to delayed diagnosis and disease progression. To identify potential biomarkers, we profiled miRNA expression in serum, saliva, and vaginal mucus from 20 women (10 with endometriosis and 10 controls) using next-generation sequencing. Differentially expressed miRNAs were identified, and their predicted targets underwent Gene Ontology and KEGG pathway enrichment analyses. Serum proteomics by data-independent acquisition LC\u2013MS/MS was integrated with miRNA data to construct potential miRNA\u2013protein interaction networks. Distinct miRNA profiles were observed across the three bodily fluids, with serum showing the most abundant miRNAs and saliva the lowest. Thirteen, three, and six differentially expressed miRNAs were detected in serum, saliva, and vaginal mucus, respectively. Enrichment analysis implicated apoptosis, Wnt signaling, autophagy, and cellular senescence. Integrated analysis revealed 59 upregulated serum proteins targeted by dysregulated miRNAs, including WNK2, CD44, USP15, GNAI3, HUWE1, and NRAS. ROC analysis suggested that serum miR-200a-3p and miR-200b-3p, may have potential utility as noninvasive biomarkers for the diagnosis and monitoring of endometriosis, pending further validation.\n\nID: 41570918\nTitle: Targeting endometrial stem cell in endometriosis treatment, a scoping review.\nAbstract: Endometriosis is characterized by the ectopic implantation of endometrial tissue affecting reproductive-aged women. Available therapies have still unmet needs namely due to recurrence rates and systemic side effects. Emerging evidence suggests endometrial stem cells (EnSCs) contribution in disease pathogenesis, including mesenchymal stem cells (E-MSCs), epithelial progenitor cells (EPCs), and side population cells (ESPs). These stem/progenitor cells are involved in proliferation, migration, and angiogenesis, contributing to endometriosis genesis and persistence. Targeting EnSCs and their regulatory pathways present a promising therapeutic strategy to improve unmet needs in endometriosis. This scoping review was based on a systematic literature search conducted in PubMed, EMBASE, and Web of Science considering studies published after 2000. Inclusion criteria focused on original research articles exploring the role and targeting of EnSCs in endometriosis, following PRISMA-ScR guidelines. Data were synthesized through narrative and descriptive methods. The review structures key pathways and therapeutic agents targeting EnSCs in endometriosis. Notch1, PI3K/Akt, Wnt/\u03b2-catenin, and JAK/STAT signalling are pathways that regulate proliferation, migration and survival of EnSCs in endometriosis. Agents such as metformin, lovastatin, sorafenib, quinagolide, and \u03b3-secretase inhibitors demonstrated potential to modulate stemness, leading to a decrease in inflammation, migration and apoptosis. Anti-angiogenic agents showed efficacy in reducing lesion size In vivo, targeting E-MSCs. Exosomes emerge as a cell-free approach, derived from menstrual stem cells (MenSCs) or ginger-based nanoparticles and exhibited properties essential for endometriosis treatment, directed to ectopic stem cells. EnSCs sustain aberrant cellular behaviours in endometriosis. Targeting EnSCs and their related pathways may be an innovative, individualized, and disease-modifying strategy. Pharmacological modulation, gene therapy and exosome are strategies for stem cell inhibition in endometriosis, being a promising avenue for future research leading to application in clinical practice.\n\nID: 41378821\nTitle: Optimizing Exosome Lipid Hybrid Nanoparticles for Enhanced siRNA Delivery and Improved Therapeutic Anticancer Efficacy In Vivo.\nAbstract: Exosome lipid hybrid nanoparticles (ELNs) have emerged as promising drug delivery vehicles, integrating the innate targeting capabilities of exosomes with efficient cytosolic delivery of lipid nanoparticles. However, despite growing interest, the development of ELNs for nucleic acid delivery remains a formidable challenge, compounded by diverse production methods and a lack of systematic approaches to optimize their formulation and performance. This study employed a Box-Behnken design and two fabrication methods: freeze-thaw and sonication, to optimize the formulation of ELNs derived from exosomes of five distinct cancer cells. Formulation criteria focused on maximizing the fusion efficiency while minimizing particle size. The impact of the fusion method on cellular association and gene silencing of promising therapeutic targets, CD24, CD44, and CD47, was evaluated. The optimized formulations were subsequently assessed for therapeutic efficacy in 4T1 and B16F10 tumor models. Through careful manipulation of formulation variables, we obtained optimal ELNs with fusion efficiencies exceeding 50% and particle sizes under 170 nm while preserving exosomal markers CD9, CD63, and CD81. Cellular association studies revealed that ELNs specifically targeted their parental cell line, achieving \u223c2.5-fold higher siRNA association compared to LNPs. Furthermore, the optimized ELNs facilitated the delivery of therapeutic siRNAs, resulting in robust gene silencing and consequently improved the in vitro macrophage-mediated phagocytosis of treated cancer cells. In vivo studies using 4T1 and B16F10 tumor models highlighted the enhanced therapeutic potential of the optimized ELNs, as evidenced by significant tumor targeting and growth inhibition. These findings underscore the importance of systematic formulation and method optimization in advancing ELNs as effective nucleic acid delivery platforms for cancer therapy.\n\nID: 41303437\nTitle: Mechanistic Insights into the Anti-Inflammatory and Anti-Proliferative Effects of Selected Medicinal Plants in Endometriosis.\nAbstract: Endometriosis involves oestrogen-dependent chronic inflammation and the abnormal proliferation of ectopic endometrial tissue. Conventional hormonal therapies suppress systemic oestrogen, but do not fully address local oxidative and inflammatory signalling. This review provides a mechanistic synthesis of recent molecular evidence. This evidence is on four FDA-recognized (Food and Drug Administration) medicinal plants. These are Curcuma longa, Zingiber officinale, Glycyrrhiza glabra, and Silybum marianum. The review highlights their capacity to modulate key intracellular pathways. These pathways are implicated in endometriosis. The review covers the integration of phytochemical-specific actions within NF-\u03baB- (nuclear factor kappa-light-chain-enhancer of activated B cells), COX-2-(Cyclooxygenase-2), PI3K/Akt-(PI3K/Akt signaling pathway), Nrf2/ARE-(Nuclear factor erythroid 2-related factor 2) and ER\u03b2-(Estrogen receptor beta) mediated networks, which jointly regulate cytokine secretion, apoptosis, angiogenesis and redox balance in endometrial lesions. Curcumin downregulates COX-2 and aromatase while activating Nrf2 signalling, shogaol from ginger suppresses prostaglandin synthesis and induces caspase-dependent apoptosis, isoliquiritigenin from liquorice inhibits HMGB1-TLR4-NF-\u03baB (High Mobility Group Box 1, Toll-like receptor 4) activation, and silymarin from milk thistle reduces IL-6 (Interleukin-6) and miR-155 (microRNA-155) expression while enhancing antioxidant capacity. Together, these phytochemicals demonstrate pharmacodynamic complementarity with hormonal agents by targeting local inflammatory and oxidative circuits rather than systemic endocrine axes. This mechanistic framework supports the rational integration of phytotherapy into endometriosis management and identifies redox-inflammatory signalling nodes as future translational targets.\n\nID: 41276243\nTitle: Liver cancer stem cells as novel diagnostic biomarkers.\nAbstract: Hepatocellular carcinoma (HCC), the most prevalent form of primary liver cancer, remains a major global health challenge because of its late diagnosis, high recurrence rate, and limited therapeutic response. Recent advances in cancer biology have identified liver cancer stem cells (LCSCs) as a subpopulation within tumors that possess self-renewal capacity, tumorigenic potential, and resistance to conventional therapies. These cells are characterized by distinct surface markers, such as CD133, EpCAM, CD44, CD90, and ALDH1, and aberrant activation of signaling pathways, including the Wnt/\u03b2-catenin, Notch, Hedgehog, and TGF-\u03b2 pathways. Emerging evidence suggests that LCSCs not only contribute to tumor initiation and progression but also serve as novel diagnostic biomarkers for early detection, prognosis stratification, and therapeutic monitoring in HCC. Circulating LCSC-derived extracellular vesicles and transcriptomic signatures offer promising avenues for noninvasive liquid biopsy approaches. This review synthesizes current findings on the molecular characterization of LCSCs, their clinical relevance, and the potential integration of LCSC biomarkers into precision oncology workflows. Targeting LCSCs may increase diagnostic accuracy and pave the way for more effective, stem cell-directed therapies in liver cancer management.\n\nID: 41071973\nTitle: Extracellular Vesicles as Novel Biomarkers for Tumor Association in Intermediate-Risk Paraneoplastic Neurologic Syndromes.\nAbstract: Paraneoplastic neurologic syndromes (PNS) are cancer-related neurologic disorders caused by an autoimmune response targeting both the tumor and the nervous system. Identifying new biomarkers for early cancer detection could improve treatment outcomes. Tumor-derived cells release extracellular vesicles (EVs) carrying tumor-specific molecular signatures, which can help distinguish patients with cancer even in early stages. The aim of this study was to assess the potential of EVs as biomarkers to enhance cancer detection in patients with PNS. This observational and multicenter study included 27 patients with tumor-associated PNS, 26 with suspected PNS without a tumor, 35 with cancer, and 32 healthy controls. Subsequently, among the patients with PNS, individuals were subclassified according to the PNS-Care Score as definite, probable, possible, and non-PNS. Total EVs were isolated from blood by precipitation and from B cells, T cells, and neurons by immunoisolation. To identify a biomarker for diagnostic refinement and clinical stratification, EV levels, size, and protein content were compared across study groups. To find a tumor biomarker in intermediate-risk cases, the possible association between EV protein content and cancer detection in intermediate-risk syndromes was analyzed. Patients with tumor-associated PNS showed significantly higher circulating EV levels compared with those with suspected PNS without evidence of a tumor (p = 0.028). Moreover, total EV levels, along with B cell-derived EVs, effectively differentiated patients with definite PNS from those with probable (p = 0.05) and possible (p = 0.006) PNS. A cutoff value of 2.10 \u00d7 1010 particles/mL EVs was identified, above which diagnosis of PNS was definite, with 86% sensitivity and 81% specificity. Proteomic analysis identified specific proteins, including ACADM, HPT, ACTBL, and CCAR2, as markers of definite PNS, differentiating such patients from those with probable and possible PNS, contributing to diagnostic refinement for clinical stratification. It is important to note that increased levels of EVs and CD44 distinguished intermediate-risk cases with tumors from those without. EVs may act as tumor biomarkers in patients with PNS, even in intermediate-risk cases. This study provides Class IV evidence that higher circulating blood levels of EVs can distinguish between tumor-associated PNS from suspected PNS without tumor.\n\nID: 40967048\nTitle: SPP1 as a key modulator of M2 macrophage polarization promotes endometriosis progression via activation of the FAK/PI3K/AKT pathway: A bioinformatics and experimental study.\nAbstract: Endometriosis (EMs) is a gynecological disorder characterized by chronic inflammation and an aberrant immune microenvironment. In this study, we integrated the GSE6364 dataset from the GEO database to identify differentially expressed genes, and applied weighted gene co-expression network analysis (WGCNA) to pinpoint gene modules highly associated with EMs. Cross-referencing with macrophage polarization-related genes, we identified 31 key genes. Machine learning algorithms (LASSO, SVM-RFE, and Random Forest) further narrowed down five core targets: CD44, CLU, FOXO1, MET, and SPP1. Single-cell RNA sequencing revealed that SPP1 is predominantly expressed in M2-like macrophages. Functional assays demonstrated that overexpression of SPP1 promotes macrophage polarization toward the M2 phenotype and significantly enhances the proliferation and migration of human endometrial stromal cells (ihESCs). Mechanistically, SPP1+ M2-like macrophages facilitate lesion growth and invasion via activation of the FAK/PI3K/AKT signaling pathway. Histological and immunofluorescence analyses further confirmed the expression and spatial distribution of these core genes in EMs lesions. Taken together, SPP1 acts as a key regulator in M2 macrophages, playing a crucial role in immune modulation and disease progression in EMs, highlighting its potential as a diagnostic biomarker and therapeutic target.\n\nID: 40838562\nTitle: Harnessing Biomaterials for Gene Therapy in Autoimmune Disease.\nAbstract: The integration of biomaterials and gene therapy heralds a transformative approach for treating autoimmune diseases, which are characterized by immune dysregulation and chronic inflammation. Conventional therapies often suffer from systemic toxicity and nonspecific immunosuppression, highlighting the need for precision medicine strategies. This review highlights recent breakthroughs in biomaterial-assisted delivery of gene therapy tools, such as small\u00a0interfering\u00a0RNA (siRNA), messenger RNA (mRNA), and clustered regularly interspaced short palindromic repeats-CRISPR-associated 9 (CRISPR-Cas9). Advanced biomaterials, including lipid nanoparticles, polymeric micelles, inorganic nanoparticles (such as gold [Au] and graphene oxide [GO]), and extracellular vesicles (EVs), have been engineered to overcome key challenges, such as low targeting efficiency, enzymatic degradation, and off-target effects. Functionalized systems that leverage pH-, reactive oxygen species (ROS)-, or enzyme-responsive mechanisms enable spatiotemporally controlled release, thereby reducing off-target exposure and systemic toxicity, for example, by confining TNF-\u03b1 siRNA release to inflamed joints in rheumatoid arthritis (RA). In contrast, ligand/receptor-mediated targeting (such as folate and CD44) enhances tissue specificity.\u00a0This review highlights the pivotal role of biomaterials in improving the clinical translation of gene therapy, providing a roadmap for next-generation treatments that prioritize precision, durability, and minimal systemic effects.\n\nID: 40813270\nTitle: AntiCD44 antibody-conjugated gold nanoparticles for targeted photothermal therapy of endometriotic cells.\nAbstract: Endometriosis is a chronic gynecologic disease that needs newer and safer treatments. The proposed work aims to develop a nanosystem based on gold nanoparticles (AuNPs) to actively target human endometriosis CD44(+) cells and significantly reduce their viability by photothermal therapy (PTT). AuNPs stabilized by lipoic acid-Poly(ethylene glycol)-Maleimide (LA-PEG-Mal) (Au@P) were decorated with antiCD44 antibodies (Au@P_AbCD44) through maleimide chemistry. The physicochemical and biochemical approaches revealed the presence of the antibody on Au@P_AbCD44. The in vitro studies were conducted against overexpressing CD44 cells (12Z), low-expressing CD44 cells (HESC), and the normal fibroblast cell line (NIH-3T3). Following the internalization through the clathrin-mediated endocytosis, the PTT of the cell-internalized Au@P_AbCD44 was investigated using two distinct laser types, due to the differing Au@P's LSPR properties. Au@P_AbCD44 exhibited significant PTT efficacy against 12Z cells; however, GNS@P_AbCD44 required lower energy input compared to GNP@P_AbCD44. This enhanced performance is attributed to the LSPR-mediated photothermal conversion efficiency of GNS over GNPs.In both cases, the apoptotic pathway was selected by dying cells over necrotic cells. The results revealed a better photothermal ability of GNS@P_AbCD44 compared to GNP@P_AbCD44. Our findings highlight the clinical potential of gold nanostars as advanced photosensitizers for targeted photothermal therapy, offering a promising strategy for more effective and less invasive treatment of endometriosis.\n\nID: 40649777\nTitle: Pathophysiology of Endometriosis: Insights from Immunohistochemical Analysis of Ectopic and Eutopic Tissues.\nAbstract: Endometriosis is a complex gynecological disorder characterized by the presence of endometrial-like tissue outside the uterus, leading to chronic pain and infertility. Immunohistochemistry (IHC) serves as a vital technique for elucidating the molecular and cellular differences between ectopic endometriotic tissues and eutopic endometrium. IHC reveals significant variations in the expression of inflammatory markers, adhesion molecules, and cell cycle regulators. This literature review compiles findings from various studies that assess the role of key proteins, such as leukemia inhibitory factor (LIF), cyclooxygenase-2 (COX-2), and b-cell lymphoma 2 (BCL-2), across different menstrual phases and lesion types. Notably, elevated LIF levels and increased mast cell activity in ectopic tissues underscore the inflammatory landscape of endometriosis. Additionally, altered expression of adhesion molecules like integrins and cluster of differentiation 44 (CD44) suggests modified cellular interactions, while apoptotic markers reveal a survival advantage for ectopic cells. These insights enhance our understanding of endometriosis pathophysiology.\n\nID: 40567500\nTitle: Intercellular communication between extracellular vesicles from conditioned macrophages and breast cancer cells drives endocrine therapy resistance.\nAbstract: Breast cancer is a leading cause of cancer-related mortality among women, with nearly 70% of cases being estrogen receptor-positive (ER+). While endocrine therapies, such as tamoxifen, have significantly improved patient outcomes, resistance-whether intrinsic or acquired-remains a major clinical challenge that limits treatment efficacy. Emerging evidence suggests that endocrine resistance is often driven by the presence and expansion of cancer stem cells (CSCs), which contribute to recurrence, metastasis, and therapeutic failure. The tumor microenvironment (TME), including immune cells like macrophages, soluble factors, and extracellular vesicles (EVs), plays a crucial role in promoting tumor progression and therapy resistance. EVs are small lipid bilayer-bound particles that facilitate intercellular communication by transferring bioactive cargo capable of reprogramming recipient cells. To investigate the role of macrophage-derived EVs in endocrine resistance, we isolated EVs from TNF-\u03b1-conditioned macrophages (TNF EVs) and treated MCF-7 ER+ breast cancer cells with these vesicles. We assessed changes in proliferation, migration, epithelial-mesenchymal transition (EMT), CSC-like properties, and tamoxifen resistance. Additionally, we evaluated whether tumor-derived EVs modulate macrophage polarization by analyzing the expression of PD-1 and other immunomodulatory markers. TNF EV-treated MCF-7 cells showed significantly increased proliferation, enhanced migratory behavior, and morphological changes associated with EMT. Importantly, treated cells developed a stem-like phenotype, characterized by a larger CD44High/CD24Low subpopulation and improved spheroid-forming ability. These features correlated with sustained proliferation even in the presence of tamoxifen, supporting the development of endocrine resistance. Furthermore, EVs derived from tumor cells triggered macrophage polarization toward a tumor-associated macrophage (TAM) profile, with increased PD-1 expression, indicating a role in immune suppression and tumor immune evasion. These findings emphasize the dual role of TNF-\u03b1-conditioned macrophage-derived EVs in driving both endocrine resistance and immune modulation in ER+ breast cancer. By promoting stemness, EMT, and tamoxifen resistance, as well as inducing immunosuppressive macrophage polarization, these EVs emerge as key contributors to tumor progression. Our study highlights the therapeutic potential of targeting EV-mediated communication to overcome endocrine resistance and enhance clinical outcomes for ER+ breast cancer patients. This work establishes a critical framework for future studies aimed at harnessing EVs as therapeutic targets or biomarkers in breast cancer management.\n\nID: 40468893\nTitle: Hyaluronic acid-engineered milk extracellular vesicles to target triple negative breast cancer through CD44.\nAbstract: Cancer therapy remains a challenge in healthcare, particularly in the context of triple-negative breast cancer (TNBC), where targeted therapies are still scarce. Addressing this issue, our study explores a novel targeting approach using small extracellular vesicles (sEVs) isolated from cow milk, functionalized with hyaluronic acid (HA) to target the overexpressed cluster of differentiation 44 (CD44) cell surface receptor in TNBC cells. A method for isolating sEVs from cow milk was optimized, and the obtained sEVs were fully characterized in terms of size, morphology, and protein markers. Subsequently, milk-derived sEVs were covalently bound with HA of varying molecular weights (MW, 20-60\u2009kDa, 250\u2009kDa, 1000-1600\u2009kDa) and binding and internalization dynamics were investigated. Breast cancer cell lines, MDA-MB-231 (TNBC and CD44+) and MCF-7 (CD44-), were used as in vitro models to evaluate CD44 selectivity. The binding and internalization studies unveiled enhanced selectivity of functionalized sEVs for CD44-overexpressing cells compared to non-functionalized sEVs. Notably, higher MW HA exhibited enhanced binding capacity, with partial internalization occurring through CD44 endocytic mechanisms. In summary, this work introduces a sEVs isolation method and sheds light on the role of HA MW in enhancing cellular uptake of CD44 overexpressing cancer cells.\n\nID: 40168801\nTitle: Metabolic-associated fatty liver disease (MAFLD) promotes the progression of hepatocellular carcinoma by enhancing KIF20A expression.\nAbstract: Compared to other HCC, those related to MAFLD exhibit distinct prognostic differences. This article aims to elucidate the impact of MAFLD on HCC prognosis through the lens of KIF20A, thereby providing a theoretical foundation for targeted therapies in MAFLD-related HCC. We employed the Weighted gene co-expression network analysis (WGCNA) method alongside the Mime package to identify key genes associated with MAFLD-related HCC. Subsequently, we utilized OCLR and CytoTRACE algorithms to evaluate the relationship between these genes and HCC stemness. The R package was employed to conduct immunological analyses on both mRNA sequencing and single-cell data. We validated the effects of core genes on HCC through experimental approaches, including cell culture, Transwell assays, Western Blot, and proliferation assays. Finally, we predicted potential therapeutic drugs using the OncoPredict software package. WGCNA identified the cyan module associated with MAFLD in GSE135251 and the blue module linked to HCC in TCGA. Further analysis identified KIF20A as the core gene in MAFLD-related HCC. Utilizing the OCLR and CytoTRACE algorithms, KIF20A was found to correlate with mRNA stemness index (mRNAsi). Analysis of public databases revealed that KIF20A promotes immune tolerance through the SPP1-CD44 pathway and drives HCC progression via the G2M checkpoint. Experimental results demonstrated that lipotoxic damage in HCC cells and small extracellular vesicles (sEVs) derived from these cells upregulate KIF20A, thereby accelerating HCC progression. Finally, OncoPredict and AutoDock were employed to predict drugs targeting KIF20A. MAFLD-related HCC can elevate KIF20A levels and promote tumor proliferation and migration.\n\nID: 39957840\nTitle: Engineering and Monitoring the Sustained Release of Extracellular Vesicles from Hydrogels for In Vivo Therapeutic Applications.\nAbstract: Extracellular vesicles (EVs) are gaining interest in regenerative medicine and biomaterials have been shown to extend EV bioavailability following delivery. Here, we report the labeling of both hydrogels and EVs to better understand hydrogel design for sustained EV release into tissues. Shear-thinning hydrogels were engineered using guest-host (i.e., adamantane-cyclodextrin) modifications to hyaluronic acid (GH), as well as GH hydrogels with the addition of gelatin crosslinked via transglutaminase (GH+Gel) to temporally control hydrogel properties. When labeled with a near-IR dye and injected into rat myocardial tissue, the GH+Gel hydrogel was retained (>14 days) longer than the GH hydrogel alone (~7 days), likely due to the added gelatin network. To overcome challenges associated with common EV labeling methods, we utilized a highly versatile metabolic labeling methodology via the incorporation of Ac4ManNAz during EV synthesis to introduce azide groups that could then be reacted with DBCO-dyes. When injected in saline, EVs were cleared within 24 hours in hearts; however, hydrogels enhanced EV retention, with levels based on hydrogel degradation behavior, namely >14 days for GH+Gel hydrogel and ~7 days for GH hydrogel alone. These findings support the use of hydrogels in EV therapies to help retain their presence at desired tissue sites.\n\nID: 39923538\nTitle: Glycoengineered stem cell-derived extracellular vesicles for targeted therapy of acute kidney injury.\nAbstract: Acute kidney injury (AKI) is associated with high morbidity and mortality rates, primarily due to the lack of effective therapeutic options for kidney repair. To restore the biological function of injured kidney, there is a need to protect renal tubular epithelial cells (RTECs) and regulate M1 macrophages, responsible for progress of AKI. Herein, based on metabolic glycoengineering-mediated click chemistry, we prepare the engineered extracellular vesicles (pSEVs), derived from PEGylated hyaluronic acid (HA)-modified mesenchymal stem cells. Owing to their cell-protective and anti-inflammatory properties, pSEVs effectively prevent the apoptosis of RTECs and inhibit the polarization of macrophages into an inflammatory phenotype in vitro. When systemically administered into the cisplatin-induced AKI animal model, pSEVs selectively accumulate in injured kidneys via HA-mediated binding to CD44 and toll-like receptor4 which are over-expressed on RTECs and M1 macrophages, respectively. This targeted delivery efficiently alleviates AKI-related symptoms, as evidenced by delayed kidney weight reduction, and decreased levels of creatinine, blood urea nitrogen, and neutrophil gelatinase-associated lipocalin. Overall, pSEVs show potent anti-inflammatory effects and specific targeting to injured kidneys, presenting a considerable potential as the therapeutics for AKI.\n\nID: 39829388\nTitle: A cRGD-modified liposome for targeted delivery of artesunate to inhibit angiogenesis in endometriosis.\nAbstract: Currently, hormonal therapy for endometriosis faces challenges in achieving a balance between treatment and preserving the chance of pregnancy. Therefore, the development of non-hormonal therapy holds significant clinical importance. Angiogenesis is a hallmark of endometriosis, and anti-angiogenic therapies targeting the hypoxia-inducible factor-1\u03b1 (HIF-1\u03b1) pathway are considered potential approaches for endometriosis. However, angiogenesis is also involved in numerous physiological processes, including pregnancy, and systemic anti-angiogenesis may lead to severe adverse effects. To address this, a cRGD-modified liposome nanodrug (cRGD-LP-ART) is synthesized, which enhances drug efficacy while reducing adverse reactions. Artesunate (ART), a non-hormonal drug used to treat malaria, has shown anti-angiogenic effects beyond its original indications in various benign and malignant diseases. With cRGD modification, cRGD-LP-ART can target ectopic lesions and inhibit local angiogenesis by suppressing the HIF-1\u03b1/vascular endothelial growth factor (VEGF) pathway. Furthermore, cRGD-LP-ART exhibits better therapeutic effects than free ART, without affecting ovarian function or causing atrophy of the eutopic endometrium, making it a promising new option for non-hormonal therapy of endometriosis. As a combination of liposomes and a clinically approved drug, cRGD-LP-ART holds great potential and clinical prospects for the treatment of endometriosis.\n\nID: 39798208\nTitle: A transcriptomic analysis of the interplay of ferroptosis and immune filtration in endometriosis and identification of novel therapeutic targets.\nAbstract: Endometriosis is an inflammatory disease, involving immune cell infiltration and production of inflammatory mediators. Ferroptosis has recently been recognized as a mode of controlled cell death and the iron overload and peroxidative environment prevailing in the ectopic endometrium facilitates the occurrence of ferroptosis. In the current investigation, gene expression data was obtained from the dataset GSE7305.The variation in infiltration of immune cells amongst the samples with endometriosis and normal tissue was analysed using the CIBERSORTx tool which revealed higher infiltration of T cells gamma delta, macrophages M2, B cells na\u00efve, T cells CD4 memory resting cells, plasma cells, T cells CD8 and mast cells activated in the tissue samples with endometriosis. An overlap of the differentially expressed genes (DEGs) and ferroptosis related genes revealed 32 ferroptosis related DEGs (FR-DEGs). GO and KEGG pathway analysis showed the FR-DEGs to be enriched in ferroptosis. The PPI network of the FR-DEGs was constructed and TP53, HMOX1, CAV1, CDKN1A, CD44, EPAS1, SLC2A1, MAP3K5, GCLC and FANCD2 were identified as the hub genes. Pearson correlation revealed significant correlation between the hub genes and infiltrating immune cells in endometriosis, thereby suggesting existence of a regulatory crosstalk between immune responses and ferroptosis in endometriosis. Hub gene- miRNA network analysis revealed that 7 of the 10 hub genes were targets of 3 miRNAs -hsa-miR-20a-5p, hsa-miR-16-5p and hsa-miR-17-5p, thereby providing further insight into the regulatory mechanisms underlying disease progression. Predictive analysis and cross validation studies revealed TP53 and CDKN1A as common targets of hsa-miR-16-5p, hsa-miR-17-5p, and hsa-miR-20a-5p, thereby revealing their regulatory roles in ferroptosis and immune modulatory pathways relevant to endometriosis. The present study indicates an important role of both immune dysregulation and ferroptosis in the pathogenesis of endometriosis and identifies ferroptosis related hub genes and their miRNA regulators as favourable novel targets for further studies and therapeutic interventions.\n\nID: 39766023\nTitle: Molecular Profiling of A549 Cell-Derived Exosomes: Proteomic, miRNA, and Interactome Analysis for Identifying Potential Key Regulators in Lung Cancer.\nAbstract: Exosomes, nano-sized extracellular vesicles released by all cells, play a key role in intercellular communication and carry tumorigenic properties that impact surrounding or distant cells. The complexity of the exosomal molecular interactome and its effects on recipient cells still remain unclear. This study aims to decipher the molecular profile and interactome of lung adenocarcinoma A549 cell-derived exosomes using multi-omics and bioinformatics approaches. We performed comprehensive morphological and physicochemical characterization of exosomes isolated from cell culture supernatant of A549 cells in vitro, using DLS, cryo-TEM, Western blot, and flow cytometry. Proteomic and miRNA high-throughput profiling, coupled with bioinformatics network analysis, were applied to elucidate the exosome molecular cargo. A comparative miRNA analysis was also conducted with exosomes derived from normal lung fibroblast MRC-5 cells. Exosomes exhibited an average size of ~40 nm and disk-shaped lipid bilayer structures, with tetraspanins CD9 and CD63 validated as exosomal markers. Proteomic analysis identified 68 proteins, primarily linked to the extracellular matrix organization and metabolic processes. miRNA sequencing revealed 72 miRNAs, notably hsa-miR-619-5p, hsa-miR-122-5p, hsa-miR-9901, hsa-miR-7704, and hsa-miR-151a-3p, which are involved in regulating metabolic processes, gene expression, and tumorigenic pathways. Th integration of proteomic and miRNA data through a proteogenomics approach identified dually affected genes including ERBB2, CD44, and APOE, impacted by both exosomal miRNA targeting and protein interactions through synergistic or antagonistic interactions. Differential analysis revealed a distinct miRNA profile in A549 exosomes, associated with cancer-related biological processes, compared to MRC-5 exosomes; notably, hsa-miR-619-5p emerged as a promising candidate for future clinical biomarker studies. The network analysis also revealed genes targeted by multiple upregulated tumor-associated miRNAs in potential exosome-recipient cells. This integrative study provides insights into the molecular interactome of lung adenocarcinoma A549 cell-derived exosomes, providing a foundation for future research on exosomal cargo and its role in tumor cell communication, growth, and progression.\n\nID: 39565506\nTitle: Effects of Exosomes from Menstrual Blood-derived Stem Cells and Ginger on Endometriotic Stem Cells.\nAbstract: Menstrual blood-derived stem cells from endometriosis patients (E-MenSCs) have different gene expression patterns than those from healthy nonendometriotic females (NE-MenSCs). Exosomes extracted from mesenchymal stem cells and plants are considered for the treatment of various diseases. This study aimed to compare the effects of exosomes derived from NE-MenSCs (C-exos) and those from the roots of ginger (P-exos) on E-MenSCs. E-MenSCs at the third passage were used, and after evaluating the effective dosage with MTT, C-exos (200 \u00b5g/mL) or P-exos (100 \u00b5g/mL) were added to treat them. Following a 72-h incubation, the cells were analyzed with annexin V/PI test to evaluate the apoptosis rate. Also, genes related to inflammation (IL-6, IL-8, IL-1\u03b2, NF-\u03baB, COX2), cell cycle (Cyclin D1), the steroid pathway (ESR1), migration and invasion (MMP-2, MMP-9, VEGF), and the apoptosis pathway (BAX, BCL2) were detected by real-time PCR. Apoptosis was increased in both the P- and C-exos groups. The expression levels of IL-6 and IL-1\u03b2 were significantly lower in the P-exos group than in the E-MenSCs group. The expression levels of IL-8, NF-\u03baB, COX-2, and MMP-9 were significantly decreased in both the P-exos group and the C-exos group. The expression level of VEGF was significantly lower in the P-exos group than in the E-MenSCs group. The BAX/BCL2 ratio was much lower in the P-exos group than in the E-MenSCs group. In this study, we established the feasibility of using a novel natural nontoxic material to target endometriotic mesenchymal stem cells to modify their gene expression and function toward healthy cells. Both C-exos and P-exos showed positive effects on the gene expression and function of endometriotic cells. Considering that plant exosomes are easier to access and less expensive, they can be considered for clinical use in improving the symptoms of endometriosis patients.\n\nID: 39551341\nTitle: Hyaluronic acid-modified extracellular vesicles for targeted doxorubicin delivery in hepatocellular carcinoma.\nAbstract: Hepatocellular carcinoma (HCC), a prevalent and deadly cancer, poses a significant challenge with current treatments due to limitations such as poor stability, off-target effects, and severe side effects. Extracellular vesicles (EVs), derived from tumor cells, have the remarkable ability to home back to their cells of origin and can serve as Trojan horses for drug delivery. CD44, a cell surface glycoprotein, promotes cancer stem cell-like properties and is linked to poor prognosis and resistance to chemotherapy in HCC. Therefore, targeting CD44-expressing HCC cells is of interest in the development of novel therapeutic strategies for the treatment of HCC. In this study, we developed tumor cell-derived EVs (TEVs) functionalized with hyaluronic acid (HA) to serve as natural carriers for the precise delivery of doxorubicin (Dox), which specifically targets HCC cells expressing CD44. Our results demonstrated that HA-engineered EVs (HA-EVs) significantly enhanced Dox accumulation within HCC cells. In a mouse model, HA-EVs effectively delivered Dox to tumors, suppressing their growth and progression while minimizing systemic toxicity. This study demonstrates the potential of HA-functionalized EVs as a novel and targeted therapeutic platform for HCC, offering a valuable strategy for improving drug delivery and patient outcomes. This study presents a promising strategy to advance targeted chemotherapy for HCC and address the challenges associated with conventional treatments. Engineered HA-functionalized EVs offer a tailored and efficient approach to increase drug delivery precision, underscoring their potential as a novel therapeutic platform in the realm of HCC treatment.\n\nID: 39520385\nTitle: Ligand-Tethered Extracellular Vesicles Mediated RNA Therapy for Liver Fibrosis.\nAbstract: Liver fibrosis poses a significant global health burden, in which hepatic stellate cells (HSCs) play a crucial role. Targeted nanomedicine delivery systems directed at HSCs have shown immense potential in the treatment of liver fibrosis. Herein, a bioinspired material, engineered therapeutic miR-181a-5p (a miRNA known to inhibit fibrotic signaling pathways) and targeted moiety hyaluronic acid (HA) co-functionalized extracellular vesicles (EVs) are developed. HA is incorporated onto the surface of EVs using DSPE-PEG as a linker, allowing preferential binding to CD44 receptors, which are overexpressed on activated HSCs. Our results confirmed enhanced cellular uptake and improved payload delivery, as evidenced by the increased intracellular abundance of miR-181a-5p in activated HSCs and fibrotic livers. HA-equipped EVs loaded with miR-181a-5p (DPH-EVs@miR) significantly reduce HSC activation and extracellular matrix (ECM) deposition by inhibiting the TGF-\u03b2/Smad signaling pathway, thus alleviating the progression of liver fibrosis. Additionally, DPH-EVs@miR improves liver function, ameliorates inflammatory infiltration, and mitigates hepatocyte apoptosis, demonstrating superior hepatic protective effects. Collectively, this study reports a prospective nanovesicle therapeutic platform loaded with therapeutic miRNA and targeting motifs for liver fibrosis. The biomarker-guided EV-engineering technology utilized in this study provides a promising tool for nanomedicine and precision medicine.\n\nID: 39519195\nTitle: Extracellular Hsp70 and Circulating Endometriotic Cells as Novel Biomarkers for Endometriosis.\nAbstract: Stress-inducible heat shock protein 70 (Hsp70), which functions as a molecular chaperone and is frequently overexpressed in different cancer cell types, is present on the cell surface of tumor cells and is actively released into the circulation in free and extracellular lipid vesicle-associated forms. Since the exact pathomechanism of endometriosis has not yet been elucidated (although it has been associated with the development of endometrial and ovarian cancer), we asked whether extracellular Hsp70 and circulating endometriotic cells (CECs) reflect the presence and development of endometriosis. Therefore, circulating levels of free and lipid microvesicle-associated Hsp70 were measured using the Hsp70-exo ELISA, and the presence of circulating CECs in the peripheral blood of patients with endometriosis was determined using membrane Hsp70 (mHsp70) and EpCAM monoclonal antibody (mAb)-based bead isolation approaches. Isolated CECs were further characterized by immunofluorescence using reagents directed against cytokeratin (epithelial marker), CD45 (leukocyte marker), CD105/CD44 (mesenchymal stemness markers) and by comparative RNA analysis. Similar to the situation in patients with cancer, the levels of circulating Hsp70 were elevated in the blood of patients with histologically proven endometriosis compared to a healthy control cohort, with significantly elevated Hsp70 levels in endometriosis patients with lesions outside the uterine cavity. Moreover, CECs could be isolated using the cmHsp70.1 mAb-based, and to a lesser extent EpCAM mAb-based, bead approach in all patients with endometriosis, with the highest counts obtained using the mHsp70-targeting procedure in patients with extra-uterine involvement. The longevity in cell culture and the expression of the cytokeratins CD105 and CD44, together with differentially expressed genes related to epithelial-to-mesenchymal transition (EMT), revealed similarities between mHsp70-expressing CECs and circulating tumor cells (CTCs) and suggest a mesenchymal stem cell origin. These findings support the involvement of mHsp70-positive stem cell-like cells in the development of endometriotic lesions. In summary, elevated levels of Hsp70 and CECs in the circulation could serve as liquid biopsy markers for endometriosis with extra-uterine involvement and help to elucidate the underlying pathomechanism of the disease.\n\nID: 39316769\nTitle: The missing link between cancer stem cells and immunotherapy.\nAbstract: Cancer stem cells (CSCs) are cancer cells that can self-renew and give rise to tumors. The multipotency of CSCs enables the generation of diverse cancer cell types and their potential for differentiation and resilience against chemotherapy and radiation. Additionally, specific biomarkers have been identified for them, such as CD24, CD34, CD44, CD47, CD90, and CD133. The CSC model suggests that a subset of CSCs within tumors is responsible for tumor growth. The tumor microenvironment (TME), including fibroblasts, immune cells, adipocytes, endothelial cells, neuroendocrine (NE) cells, extracellular matrix (ECM), and extracellular vesicles, has a part in shielding CSCs from the host immune response as well as protecting them against anticancer drugs. The regulation of cancer stem cell plasticity by cancer-associated fibroblasts (CAFs) occurs through specific signaling pathways that differ among various types of cancer, utilizing the IGF-II/IGF1R, FAK, and c-Met/FRA1/HEY1 signaling pathways. Due to the intricate dynamics of CSC proliferation, controlling their growth necessitates innovative approaches and much more research. Our current review speculates an outline of how the TME safeguards stem cells, their interaction with CSCs, and the involvement of the immune and inflammatory systems in CSC differentiation and maintenance. Several technologies have the ability to identify CSCs; however, each approach has limitations. We discuss how these methods can aid in recognizing CSCs in several cancer types, comprising brain, breast, liver, stomach, and colon cancer. Furthermore, we explore different immunotherapeutic strategies targeting CSCs, including stimulating cancer-specific T cells, modifying immunosuppressive TMEs, and antibody-mediated therapy targeting CSC markers.\n\nID: 39270628\nTitle: Engineering extracellular vesicles derived from endothelial cells sheared by laminar flow for anti-atherosclerotic therapy through reprogramming macrophage.\nAbstract: Extracellular vesicles (EVs) secreted by endothelial cells in response to blood laminar flow play a crucial role in maintaining vascular homeostasis. However, the potential of these EVs to modulate the immune microenvironment within plaques for treating atherosclerosis remains unclear. Here, we present compelling evidence that EVs secreted by endothelial cells sheared by atheroprotective laminar shear stress (LSS-EVs) exhibit excellent immunoregulatory effects against atherosclerosis. LSS-EVs demonstrated a robust capacity to induce the conversion of M1-type macrophages into M2-type macrophages. Mechanistic investigations confirmed that LSS-EVs were enriched in miR-34c-5p and reprogrammed macrophages by targeting the TGF-\u03b2-Smad3 signaling pathway. Moreover, we employed click chemistry to modify hyaluronic acid (HA) on the surface of LSS-EVs, enabling specific binding to the CD44 receptor expressed by inflammatory macrophages within plaques. These HA-modified LSS-EVs (HA@LSS-EVs) exhibited exceptional abilities for targeting atherosclerosis and demonstrated promising therapeutic effects both in vitro and in vivo.\n\nID: 42602254\nTitle: Multifunctional hyaluronic acid-modified hollow MnO2 nanoplatform co-delivering with L-Arginine and Regorafenib for synergistic therapy against colorectal cancer.\nAbstract: The high rates of recurrence and metastasis in colorectal cancer (CRC), coupled with its immunosuppressive tumor microenvironment (TME), severely constrain patient survival. To overcome the limitations of monotherapies, this study developed a multifunctional targeted nanoplatform (RLHMnH). This system consists of a hyaluronic acid (HA)-modified hollow manganese dioxide (H-MnO2) nanocarrier co-loaded with the anti-angiogenic drug Regorafenib (Reg) and the nitric oxide precursor L-Arginine (L-Arg) for synergistic triple therapy against CRC. The platform leverages HA-mediated CD44 receptor targeting to achieve enhanced tumor accumulation. Within the TME, the H-MnO2 framework undergoes rapid responsive decomposition. On one hand, Within the acidic and GSH-rich TME, H-MnO2 undergoes reductive degradation to release Mn2+, concomitantly depleting GSH and disrupting redox homeostasis. The released Mn2+ further catalyzes Fenton-like conversion of endogenous H2O2 into highly cytotoxic \u00b7OH, thereby inducing oxidative damage and tumor cell apoptosis. On the other hand, the concomitantly released Reg effectively blocks tumor angiogenesis by inhibiting the VEGFR2 signaling pathway, while L-Arg generates nitric oxide, synergistically reversing drug resistance, alleviating hypoxia, and activating anti-tumor immunity. Both in vitro and in vivo experiments demonstrated that RLHMnH, through integrating the triple synergistic mechanisms of CDT, anti-angiogenesis, and gas therapy, achieved a remarkable tumor inhibition rate of \u223c75% in a CT26 xenograft model and potently suppressed CT26\u202fcell viability to below 20% at 72\u202fh, showcasing significant suppression of CRC. This study provides an innovative nano-carrier-based synergistic strategy to overcome the current therapeutic bottlenecks in CRC treatment.\n\nID: 42530786\nTitle: Nanomaterial Platforms for Endometriosis: A Systematic Review.\nAbstract: Endometriosis (EM) is a chronic, estrogen-dependent inflammatory disease affecting approximately 10% of women of reproductive age worldwide, causing debilitating pelvic pain, infertility, and substantially impaired quality of life. Conventional hormonal therapies and surgery are limited by systemic side effects, high recurrence rates, and failure to maintain adequate drug concentrations at ectopic lesion sites. Nanotechnology-based drug delivery has emerged as a promising strategy for directing therapeutic agents to ectopic lesion sites, potentially reducing the systemic toxicity that limits current pharmacological options. We systematically review three nanomaterial platforms-hydrogels, extracellular vesicles (EVs), and inorganic nanoparticles-with attention to their physicochemical properties, therapeutic rationale, and preclinical findings, as well as the specific strengths and unresolved limitations of each platform. We further compare how each platform addresses the core pathological processes of EM, namely, persistent inflammation, progressive fibrosis, and pathological angiogenesis. We hope that this review will assist researchers in comparing nanocarrier strategies and identifying more realistic pathways for clinical application in EM.\n\nID: 42482624\nTitle: Associations between body mass index and retained placenta in delivery hospitalizations: Analysis of the Nationwide Inpatient Sample, 2016-2020.\nAbstract: Retained placenta (RP) is an obstetric complication associated with postpartum hemorrhage, sepsis, and maternal morbidity. While maternal body mass index (BMI) influences pregnancy outcomes, its associations with RP are unclear. We aimed to examine associations between BMI, demographic and clinical factors, and RP using a nationally representative inpatient dataset. This retrospective study analyzed data of women aged \u226518\u2009years with delivery hospitalizations from the US Nationwide Inpatient Sample 2016-2020. RP was identified using the ICD-10 codes. Included women were classified on the basis of BMI as non-obese (<30.0\u2009kg/m2), obese (30.0-39.9\u2009kg/m2), and morbidly obese (\u226540.0\u2009kg/m2). Weighted logistic regression analysis determined associations between study variables and RP occurrence. Among 3\u2009590\u2009940 delivery hospitalizations, 28\u2009935 women (0.8%) had RP. Multivariable analysis identified advanced maternal age (adjusted odds ratio [aOR]\u2009=\u20091.046, 95% CI: 1.044-1.049), obesity (aOR\u2009=\u20091.18), morbid obesity (aOR\u2009=\u20091.25), polycystic ovary syndrome (PCOS) (aOR\u2009=\u20091.33), endometriosis (aOR\u2009=\u20092.28), smoking (aOR\u2009=\u20091.33), multiple pregnancy (aOR\u2009=\u20092.37), uterine surgery (aOR\u2009=\u20092.04), abortion (aOR\u2009=\u20091.43), and infertility (aOR\u2009=\u20091.87) as independent risk factors for RP. Cesarean delivery (vs. vaginal delivery) was significantly associated with a lower risk of RP (aOR\u2009=\u20090.14). Subgroup analyses confirmed consistent risk factors across age, prematurity, and PPROM, with multiple pregnancy, endometriosis, PCOS, obesity, and smoking remaining significant predictors. Obesity is an independent risk factor for RP, and morbid obesity confers the highest risk. Study findings emphasize the need for patient-focused obstetric management in high-risk populations.\n\nID: 42328561\nTitle: PBMC-derived FGF, PDGF, VEGF and GM-CSF secretion in endometriosis: a case-control in vitro study.\nAbstract: Endometriosis is a chronic inflammatory disease with immune dysregulation in which angiogenic, and hematopoietic mediators are thought to contribute to ectopic lesion establishment and persistence. Whether circulating immune cells are intrinsically primed to secrete higher levels of pro-angiogenic growth factors remains unclear. This study evaluated in vitro secretion of fibroblast growth factor (FGF), platelet-derived growth factor (PDGF), vascular endothelial growth factor (VEGF) and granulocyte-macrophage colony-stimulating factor (GM-CSF) by peripheral blood mononuclear cells (PBMCs) from women with and without endometriosis. In a case-control design, women with laparoscopically and histopathologically confirmed endometriosis (n\u202f=\u202f36) and laparoscopically confirmed controls without endometriosis (n\u202f=\u202f44) were enrolled. PBMCs were isolated from peripheral blood and cultured for 24\u202fh under basal conditions or after non-specific mitogenic activation with phytohemagglutinin (PHA, 5\u202f\u03bcg/mL). Supernatant concentrations of FGF, PDGF, VEGF and GM-CSF were quantified using a multiplex bead-based immunoassay (Bio-Plex/Luminex). Between-group comparisons used nonparametric tests; univariate logistic regression explored associations with endometriosis status; and false discovery rate (Benjamini-Hochberg) adjustment was applied for multiple testing. Baseline secretion of FGF, PDGF, VEGF and GM-CSF by PBMCs did not differ significantly between women with endometriosis and controls after correction for multiple comparisons. PHA stimulation induced marked shifts in secretion profiles across participants- characterized by increases in FGF, PDGF and VEGF and a decrease in GM-CSF-but neither stimulated concentrations nor percent changes differed significantly between groups following false discovery rate adjustment. In univariate logistic regression analyses, none of the baseline growth-factor measures significantly predicted the presence of endometriosis. Under standardized in vitro culture conditions, PBMCs from women with endometriosis do not show a generalized increase in secretory capacity for the evaluated pro-angiogenic/hematopoietic growth factors compared with PBMCs from controls without endometriosis. These data do not support systemic PBMC hypersecretion of FGF, PDGF, VEGF and GM-CSF in endometriosis and are consistent with a compartmentalized model in which disease-relevant pro-angiogenic signaling is predominantly shaped within local peritoneal and lesion microenvironments.\n\nID: 42313707\nTitle: Rupture of the Uterine Artery Pseudoaneurysm Causing Late Postpartum Hemorrhage: Case Report and Literature Review.\nAbstract: Postpartum hemorrhage (PPH) remains one of the leading causes of maternal mortality worldwide. A rare but potentially life-threatening cause of secondary PPH is uterine artery pseudoaneurysm (UAP). In this case report, we present two clinical cases of UAP and review the available literature summarizing clinical symptoms, diagnostic approaches, and treatment options. The first case involved a patient presenting with abdominal pain and syncope 6 days after vaginal delivery, subsequently diagnosed with a right-sided UAP and hemoperitoneum. The second patient presented with painless yet heavy vaginal bleeding and was also diagnosed with a right-sided UAP. Both patients were successfully managed with uterine artery embolization. UAP may present atypically, either with or without vaginal bleeding. Possible reported risk factors include cesarean delivery, uterine curettage, endometriosis, inflammation, cervical conization, myomectomy, and excision of cesarean scars. Transvaginal sonography is the first-line diagnostic tool due to its accessibility, while computed tomography (CT) or magnetic resonance imaging are helpful for confirmation and treatment planning. Endovascular embolization is the treatment of choice in hemodynamically stable patients due to its minimally invasive nature and favorable outcomes.\n\nID: 42194850\nTitle: Uncommon Presentations of Endometriosis: Clinicopathological Features of Abdominal Wall and Extrapelvic Lesions.\nAbstract: Background/Objectives: Abdominal wall and extrapelvic endometriosis are uncommon entities that may mimic other surgical conditions and delay diagnosis. This study evaluated their clinicopathological, diagnostic, and surgical features in a single-center case series. Methods: This retrospective study included 29 patients with histopathologically confirmed abdominal wall or extrapelvic endometriosis treated at a tertiary referral center between 2009 and 2025. Demographic and clinical characteristics, surgical history, CA-125 levels, imaging findings, lesion size, and surgical features were analyzed. Abdominal wall cases were further evaluated based on the presence of muscle or fascial invasion. Results: Abdominal wall lesions comprised 93.1% of cases, while extrapelvic lesions (6.9%) were all vaginal. Most cases had a history of cesarean section; however, one patient had no prior abdominal surgery, consistent with spontaneous disease, with concomitant endometrioma and deep infiltrating endometriosis. Muscle or fascial invasion was observed in 63.0% of cases. Both CA-125 levels (p = 0.005) and CA-125 positivity (\u226535 U/mL) (p = 0.029) were significantly higher in patients with invasion. Cyclic symptoms were present in 89.7% of patients, and mesh repair was required in two cases with large lesions. Conclusions: Abdominal wall endometriosis should be suspected in patients with cyclic pain or swelling at surgical sites, particularly after cesarean delivery, although it may occur without prior surgery. Deep muscle and fascial invasion may be associated with elevated CA-125 levels and increased CA-125 positivity, sometimes requiring wider excision and mesh repair. These findings may support earlier diagnosis and surgical planning.\n\nID: 42108431\nTitle: Effects of adenomyosis and endomyometrial junctional zone on spontaneous preterm labor : a case-control study.\nAbstract: Spontaneous preterm labor (SPL) is a significant obstetric concern, and recent literature suggests an association with adenomyosis. In this study, we compared adenomyosis and endomyometrial junctional zone (JZ) in women with and without a recent history of SPL. This case-control study was conducted between October 2019 and Mar 2021. Exclusion criteria included Iatrogenic preterm labor, a history of hormonal drug use after delivery, a history of M\u00fcllerian anomaly, endometriosis, fibroids, uterus surgery, cesarean section, and postpartum hemorrhage requiring uterine procedures. The study population consisted of women with a history of SPL or a history of full-term vaginal delivery within the last six months in the study and control groups, respectively. All participants underwent 2- and 3-dimensional transvaginal sonography six months after delivery to assess the JZ thickness and irregularity, and the presence or absence of adenomyosis. 92 women were included in this study. No significant differences were found regarding age, body mass index, parity, or prior preterm birth. The mean JZ irregularity was 2.53\u2009\u00b1\u20091.39\u00a0mm in the study group and 1.86\u2009\u00b1\u20090.72\u00a0mm in the control group (P\u2009=\u20090.004). In the overall cohort, increased JZ difference was associated with higher odds of SPL (aOR\u2009=\u20091.74). Stratifying by adenomyosis status showed that the association was stronger and remained significant in women with adenomyosis (aOR\u2009=\u20091.88), whereas it lost significance in those without adenomyosis. SPL is notably associated with the JZ characteristics and adenomyosis. Further studies are recommended to explore the relationship between these factors and pregnancy outcomes.\n\nID: 41852721\nTitle: pH-responsive CaCO3 nanoplatform amplifies SDT via calcium overload-ROS loop for deep tumor therapy.\nAbstract: Sonodynamic therapy (SDT) for deep-seated tumors is limited by tumor microenvironment (TME) barriers. We developed a hyaluronic acid (HA)-modified mesoporous calcium carbonate nanoplatform (HA/CaCO3@Ce6) to synergistically enhance calcium overload and SDT. The CD44-targeted nanoplatform demonstrated pH-responsive degradation in acidic TME, resulting in the release of Ca2+ and chlorin e6 (Ce6). The released Ca2+ induced mitochondrial calcium overload, causing 71% collapse in membrane potential and 1.6-fold increase in reactive oxygen species (ROS) generation, establishing a \"Ca2+-ROS positive feedback loop.\" This synergy triggered robust immunogenic cell death (ICD), enhancing CRT exposure by 94.2%, HMGB1 release by 46.2%, and ATP decrease by 74.5%. In vivo, it achieved 90.9% tumor inhibition and 80% 60-day survival rate, alleviated tumor hypoxia, and inhibited tumor proliferation and angiogenesis. This \"ion-interference SDT\" paradigm overcomes the limitations of SDT through self-amplified ROS cycle and provides an effective strategy for treating deep-seated solid tumor with significant clinical translation potential.\n\nID: 41832009\nTitle: Structure-function paradigms of natural polysaccharides in hepatocellular carcinoma therapy.\nAbstract: Hepatocellular carcinoma (HCC) is a major cause of cancer mortality worldwide, and its limited response to conventional chemotherapeutics underscores the need for safer, multifunctional approaches. Natural polysaccharides, complex carbohydrates derived from plants, fungi, algae, animals, and bacteria, represent a structurally diverse class of bioactive macromolecules that combine therapeutic and material properties. Their monosaccharide composition, linkage types, branching patterns, molecular weights, and charge densities determine receptor recognition, intracellular trafficking, and signaling modulation. Plant-derived polysaccharides act through asialoglycoprotein receptor engagement when galactose-rich motifs are present, alongside oxidative-stress regulation and microRNA control; fungal \u03b2-glucans engage Toll-like receptor and Dectin-1 pathways to activate immunity and sensitize tumor cells; algal fucoidans and carrageenans inhibit angiogenesis and metastasis through sulfate- and uronic-acid-dependent signaling; animal polysaccharides such as hyaluronic acid and chitosan provide CD44-targeted delivery and stromal modulation; and bacterial exopolysaccharides trigger apoptosis via charge- and topology-dependent mitochondrial collapse. Together, these systems reveal a unified structure-function paradigm that links chemical geometry to biological outcomes. Advances in derivatization, nanocarrier development, and glycomics now enable the predictive design of polysaccharide-based therapeutics with reproducible activity and reduced toxicity. This review integrates mechanistic, structural, and translational perspectives to position polysaccharides as designable molecular platforms for targeted and synergistic intervention in HCC.\n\nID: 41789111\nTitle: Dysregulated hyaluronan metabolism drives inflammation and angiogenesis in proliferative diabetic retinopathy.\nAbstract: To investigate the expression levels of enzymes and receptors of the hyaluronan (HA) pathway, including HA synthase (HAS)-2, hyaluronidase (Hyal)-1, Hyal-2, CD44 and receptor for HA-mediated motility (RHAMM) in the ocular microenvironment of patients with proliferative diabetic retinopathy (PDR) and the role of HA pathway in inflammation and angiogenesis that drive PDR initiation and progression. Epiretinal fibrovascular membranes from PDR patients, vitreous samples from PDR and nondiabetic patients, rat retinas, retinal M\u00fcller glial cells and human retinal microvascular endothelial cells (HRMECs) were studied by immunohistochemistry, ELISA, Western blot analysis and spectrofluorometric analysis. Functional studies included evaluation of in vivo blood-retinal barrier integrity and analysis of in vitro cell adhesion and angiogenesis. HA, HAS2, Hyal-1, Hyal-2, CD44, syndecan-1 and heparan sulphate levels were upregulated in PDR vitreous samples. Immunohistochemical analysis revealed expression of HAS2, Hyal-2, CD44 and RHAMM in epiretinal membranes, with significant positive correlations between angiogenic activity and HAS2, Hyal-2 and CD44 expression. Diabetes upregulated Hyal-1, CD44, RHAMM and reactive oxygen species in rat retinas. Intravitreal administration of ultralow molecular weight HA (ULMW-HA) in normal adult rats increased retinal vascular permeability and induced upregulation of phospho-NF-\u03baB, phospho-ERK1/2, VEGF, HMGB1, ICAM-1 and VCAM-1 protein levels. In M\u00fcller cell cultures, ULMW-HA induced upregulation of phospho-ERK1/2, phospho-NF-\u03baB, HMGB1, VEGF, angiopoietin-2 and MCP-1/CCL2 proteins. The ERK1/2 inhibitor U-0126 and the NF-\u03baB inhibitor BAY11-7085 attenuated ULMW-HA-induced upregulation of VEGF, angiopoietin-2 and MCP-1/CCL2 levels. The hyaluronidase inhibitor apigenin reduced the levels of VEGF and MCP-1/CCL2 induced by diabetic mimetic conditions. In cultured HRMECs, ULMW-HA induced cell migration, whereas apigenin attenuated shedding of soluble syndecan-1 induced by diabetic mimetic conditions and reduced TNF-\u03b1-induced upregulation of ICAM-1, VCAM-1 and adherence of monocytes. Abnormal HA metabolism is involved in diabetes-induced retinal endothelial dysfunction and ULMW-HA drives inflammation and angiogenesis in PDR.\n\nID: 41716606\nTitle: Uterine rupture during labor in a patient with endometriosis: A case report.\nAbstract: Uterine rupture is a rare obstetric complication, particularly in women without a prior cesarean delivery. This report describes an intrapartum posterior uterine wall rupture extending into the vagina in a patient with pre-existing endometriosis and presumed adenomyosis, highlighting endometriosis and its surgical management as potential risk factors. A term gravida with a history of two laparoscopic procedures for endometriosis presented with menstrual-like bleeding and contractions. During labor, she developed severe abdominal pain, prompting an emergency cesarean section. Intraoperatively, a 12\u00a0cm longitudinal rupture of the posterior uterine wall extending into the pouch of Douglas and the posterior vaginal fornix was identified. The defect was successfully sutured, and hysterectomy was not required. The postpartum outcome for both the mother and the newborn was satisfactory. This case underscores the importance of recognizing endometriosis and its surgical treatment as possible contributing factors to uterine rupture.\n\nID: 41713152\nTitle: Reproductive outcomes after surgical correction of congenital obstructive genital tract anomalies: A systematic review and quantitative pooled analysis of published data.\nAbstract: Congenital obstructive genital tract anomalies are rare but clinically significant causes of menstrual outflow obstruction, endometriosis, and subfertility. Surgical correction aims to restore reproductive potential, yet evidence to guide counselling on fertility and pregnancy outcomes remains fragmented. To synthesise and pool published data on fertility, obstetric, and neonatal outcomes following surgical correction of congenital obstructive anomalies, comparing outcomes across anomaly types to inform individualised counselling. A systematic review was conducted. PubMed, Emcare, CINAHL, and Scopus were searched from inception to May 2025. Studies reporting reproductive outcomes after surgical correction of imperforate hymen, transverse vaginal septum, OHVIRA-spectrum, functional non-communicating uterine horns, or cervicovaginal atresia were included. Data were extracted independently and pooled by anomaly type. Study quality was assessed using Joanna Briggs Institute tools. Ninety-six studies (41 case reports, 41 case series, and 14 retrospective cohorts) were contributed 634 fertility-related events. Infertility rates were low following imperforate hymen (8.0%) and OHVIRA-spectrum anomalies (18.2%), intermediate in functional rudimentary horns (21.2%), and high following transverse vaginal septum (52.6%) and cervicovaginal atresia (55.4%). Among achieved pregnancies, livebirth rates exceeded 80%. Preterm birth occurred in 23.7% of pregnancies and did not differ significantly by anomaly type. Caesarean delivery was frequent (55.9%), particularly after cervicovaginal reconstruction (97.6%). Birthweight was lower following cervicovaginal atresia repair, with higher rates of small-for-gestational-age infants. Gestational hypertensive disorders were associated with co-existing renal agenesis. Reproductive outcomes after surgical correction are generally favourable but vary substantially by anomaly type. These findings support individualised counselling and targeted antenatal surveillance.\n\nID: 41551762\nTitle: LRP-1/CD44-targeted regorafenib nano-delivery system leveraging anti-angiogenesis and synergistic cytotoxicity against peritoneal metastasis of colorectal cancer.\nAbstract: Peritoneal metastasis of colorectal cancer (PM-CRC) represents a major therapeutic challenge in advanced disease, where aberrant tumor vasculature contributes to poor prognosis. To address the pharmacological limitations of regorafenib (REG), this study developed a dual-receptor-targeted nanoplatform (REG@LFHA NPs) that leverages the characteristic overexpression of LRP-1 and CD44 receptors in the colorectal cancer tumor microenvironment. The nanoplatform was engineered through nanoprecipitation and electrostatic self-assembly, incorporating lactoferrin for LRP-1 targeting and hyaluronic acid for CD44 recognition. REG@LFHA NPs exert multifaceted antitumor effects through three coordinated mechanisms: potent suppression of tumor vasculature through VEGF-VEGFR pathway blockade, effectively disrupting blood and oxygen supply to induce tumor necrosis; direct tumor cytotoxicity via REG-mediated apoptosis and cell cycle arrest; and immune microenvironment remodeling through macrophage repolarization from pro-tumor M2 to antitumor M1 phenotypes. In PM-CRC models, REG@LFHA NPs demonstrated significantly enhanced tumor accumulation and therapeutic efficacy compared to free REG. Furthermore, the nanoplatform showed remarkable synergy with oxaliplatin, the first-line chemotherapeutic agent for PM-CRC, producing superior treatment outcomes through complementary mechanisms of action. This study not only establishes REG@LFHA NPs as an effective dual-targeting nanomedicine but also demonstrates their strong potential for clinical translation, particularly in combination with standard chemotherapy regimens for advanced peritoneal metastatic colorectal cancer.\n\nID: 41473030\nTitle: Copper Intrauterine Device Migration Into Cesarean Scar Niches Without Complications: A Case Report.\nAbstract: Intrauterine devices (IUDs), both hormonal and nonhormonal, are widely used contraceptive methods, with approximately 20% of reproductive-aged women worldwide utilizing them. Although IUDs are generally considered safe and effective, complications such as displacement and migration can occur. We report a rare case of copper IUD migration into a cesarean section scar niche. A 28-year-old woman presented to the emergency department with complaints of lower abdominal pain and abnormal vaginal bleeding. She had received a T-shaped copper IUD 2 years prior. Transvaginal ultrasound revealed an inverted IUD within the endometrial cavity, with one arm embedded in the cesarean scar defect. The device was successfully removed via hysteroscopy without complication. This case highlights the importance of imaging evaluation in symptomatic IUD users with a history of cesarean delivery.\n\nID: 41429389\nTitle: Quercetin-loaded zeolitic imidazolate framework-8 nanoparticles through borneol-embedded hyaluronic acid hydrogel for ischemic stroke treatment.\nAbstract: Ischemic stroke (IS), widely known for the frequency and the high disability rate, remains challenging to conquer due to its complex pathology. The therapeutic application of Quercetin (QC), a natural flavonoid with powerful antioxidant and anti-inflammatory activities, its therapeutic application is limited by low bioavailability\uff0cand so is the blood-brain barrier (BBB)\uff0cwith a major obstacle in the effective delivery of drugs to the brain. In view of the above, this study aimed to develop an intranasal administration (IN) system based on borneol (Bo) embedded thermosensitive hydrogel, to deliver QC-loaded zeolite imidazolate framework-8 (ZIF-8) nanoparticles (QC@ZIF-8 NPs) for the synergistic treatment of IS. Up to now, QC@ZIF-8 NPs with uniform particle size and pH-responsive release characteristics has been successfully synthesized. And with its ideal property of temperature-sensitivity, bio-compatibility and release-sustainability, the prepared Bo/QC@ZIF-8-Gel was evaluated through in vitro experiments (MTT, LDH, ROS, JC-1, immunofluorescence, ELISA) to test its neuro-protective, anti-inflammatory, and antioxidant properties. The results showed that Bo/QC@ZIF-8-Gel effectively scavenged ROS, attenuated OGD/R-induced cell damage, and significantly lowered the levels of pro-inflammatory factors (TNF-\u03b1, IL-1\u03b2, IL-6) by promoting microglial polarization from the pro-inflammatory M1 phenotype to the anti-inflammatory M2 phenotype. Besides, pharmacokinetic studies in rats showed that borneol significantly promoted drug enrichment in the brain following the IN of this gel system. Furthermore, in a rat model of the middle cerebral artery occlusion (MCAO), we evaluated the brain targeting of Bo/QC@ZIF-8-Gel (via in vivo imaging), as well as its effects on the cerebral infarct volume and the neurological function. The results showed that Bo/QC@ZIF-8-Gel treatment significantly reduced the cerebral infarct volume, improved the neurological function scores, increased the number of surviving neurons, effectively inhibited the inflammatory response in the brain, and promoted the neurological recovery in MCAO model rats. In summary, Bo/QC@ZIF-8-Gel represents a promising strategy for the treatment of IS.\n\nID: 41299007\nTitle: Personalized Vaginal Drug Delivery through 3D Printing: Techniques, Challenges, and Future Perspectives.\nAbstract: Vaginal disorders in reproductive\u2011age women, including bacterial vaginosis (affecting 23-29%), endometriosis, etc., are increasing alarmingly day by day worldwide. Vaginal drug delivery (VDD) has garnered notable attention in the pharmaceutical field for the localized and systemic treatment of several hormonal and gynaecological conditions. Conventional treatments remain inadequate due to high relapse rates, local and systemic side effects, compliance, invasiveness, drug resistance, adherence, safety, etc. Additive manufacturing, particularly 3D Printing (3DP), is reshaping pharmaceutical sciences by enabling the fabrication of personalized and novel drug delivery solutions. In addition, 3D Printed VDD systems (VDDS) offer highly customized and patient-specific dosage forms that possess controlled release kinetics and precise control over drug deposition, ultimately leading to increased patient adherence. This review comprehensively examines the state-of-the-art in 3DP technologies and critical considerations such as material selection, impact on drug release mechanisms, mechanical properties, and biocompatibility of the formulations, current regulatory landscape, and future perspectives of 3DP in VDD. This eventually paves the way for better patient-centered therapeutic solutions.\n\nID: 41296460\nTitle: Non-Invasive Extracellular Vesicle Biomarkers in Endometriosis, Molecular Signatures Linking Pelvic Inflammation, Oocyte Quality, and IVF Outcomes.\nAbstract: Endometriosis impairs fertility by interfering with ovarian function, embryonic development, and endometrial receptivity. Extracellular vesicles (EVs) are recognised as non-invasive biomarkers that may indicate biological processes based on their lipid, protein, and microRNA composition. This narrative review synthesises current data on extracellular vesicle (EV) signatures in serum/plasma, menstrual blood, follicular fluid, and uterine fluid in endometriosis patients using assisted reproductive technology (ART). We highlight critical EV-mediated processes, such as progesterone signalling, fibrosis, angiogenesis, inflammation, and metabolism, and their associations with oocyte competence, embryo development, and implantation. Certain EV-miRNA profiles, including miR-22-3p, miR-320a, the miR-200 family, and miR-145-5p, have shown use for diagnostic and prognostic purposes in various investigations. These characteristics are associated with live birth, implantation, and blastocyst quality. We propose a clinical framework that incorporates (i) menstrual-blood EVs for non-invasive endotyping, (ii) serum/plasma EV profiling for baseline risk stratification, and (iii) pre-transfer uterine-fluid EV evaluation to inform embryo-transfer decisions. Translation requires standardisation, cycle phase control, and prior validation. EVs may serve as a beneficial instrument for personalised in vitro fertilisation operations for ladies experiencing infertility due to endometriosis.\n\nID: 41203214\nTitle: Nanodrug impact on female reproductive health and fetal development: From translation approaches to long-term safety concern.\nAbstract: Biomaterials for drug delivery offer significant advantages over conventional medications, including enhanced cellular uptake, improved drug stability, targeted delivery, and controlled drug release. Cutting-edge nanodrugs delivery approaches such as drugs formulations, hydrogels, films, and vaccines have been developed for diverse applications, including hormonal therapies, immunotherapy, infectious diseases, and gestational health. Tailored biomaterial systems can administer drugs for conditions such as vaginal infections, endometriosis, pregnancy disorders, reproductive cancers, and inherent messes during gestation. Designing delivery technologies for female health requires addressing unique barriers and challenges specific to the female body. Advancements in delivery technologies in other disease contexts can inform innovations in female health treatments. Delivering biomaterials and medications at the time of pregnancy may have adverse developmental consequences for the fetus, necessitating an understanding of how nanomaterials interact with reproductive systems and activate signal transduction pathways. Ensuring safety and minimizing toxicity are critical considerations, alongside developing appropriate and accessible preclinical models to facilitate clinical translation. Omics-based techniques can aid in the sustainable risk assessment and safety evaluation of nanomaterials by identifying biomolecules involved in nanotoxicity. Taking these events or exposures together with their toxicity on the female reproductive system and offspring outcomes, thus further study is required to explore, the way that nanoparticles compromise fertility and growth of embryos in humans. Long-term studies are crucial for assessing the safety of nanodrugs in pregnant female, especially concerning chronic effects from prenatal exposure. Effective development and translation of nano-drug delivery technologies for female health require collaboration among biomaterials researchers, patients, clinicians, and regulatory agencies.\n\nID: 41105328\nTitle: Advances in hyaluronic acid-based biomaterials: applications in cancer therapy, wound healing, and disease management.\nAbstract: Hyaluronic acid (HA) is a naturally occurring glycosaminoglycan and is essential in biomedical research due to its distinct properties, compatibility with biological tissues, and functions in preserving tissue hydration, lubrication, and the integrity of the extracellular matrix, a significance recognized since 1934. Its capability to develop hydrogels and react to environmental factors has provided it a strong factor for drug delivery, tissue engineering, and wound healing uses. This review emphasizes the various biomedical uses of HA-based materials, focusing on their functions in cancer treatment, wound healing, inflammation control, antibacterial properties, and antioxidant functions. In cancer treatment, HA-functionalized nanoparticles improve the targeted drug delivery by using the additional presence of CD44 receptors in cancer cells. HA-based hydrogels have demonstrated significant potential in advancing wound healing by regulating inflammatory responses, enhancing angiogenesis, and participating in the extracellular matrix remodeling. Moreover, HA's anti-inflammatory and antioxidant characteristics have been utilized in the treatment of chronic inflammatory conditions including osteoarthritis and inflammatory bowel disease. The recent developments in HA-based materials have also demonstrated their promise in antibacterial applications, diabetes control, and in treating cardiovascular and neurological conditions. The advancement of HA-based intelligent drug delivery systems and bioactive scaffolds is ongoing, presenting new treatment options for tissue repair and disease management. This review emphasizes the diverse functions of HA in both health and disease, showcasing its capacity to tackle various medical issues through cutting-edge biomedical applications.\n\nID: 40955322\nTitle: Management of uterine artery pseudoaneurysm: a case report of noninterventional treatment with systematic review.\nAbstract: Uterine artery pseudoaneurysm (UAP) is a rare but potentially life-threatening condition that can result in severe hemorrhage. Due to its nonspecific clinical presentation, it is often misdiagnosed, leading to delays in appropriate intervention. UAP commonly arises following uterine trauma, including cesarean section, vaginal delivery, and other gynecological procedures or pathologies, such as endometriosis. While selective arterial embolization is the preferred treatment, noninterventional management may be a viable alternative in selected cases. We present a case of a 33-year-old woman in her first pregnancy diagnosed with UAP at 27 gestational weeks (GW). She complained about intermittent left lower abdominal pain without vaginal bleeding. Initial imaging with Doppler ultrasonography and noncontrast magnetic resonance imaging (MRI) identified a left paracervical mass consistent with a UAP. Further imaging with contrast-enhanced MRI confirmed the diagnosis and revealed thrombosis of the lesion. Given the absence of perfusion and clinical stability, a noninterventional approach was pursued. The patient remained hemodynamically stable and was discharged after 6 days of hospitalization. At 38+4 GW, she underwent a scheduled cesarean section, and both maternal and neonatal outcomes were favorable. Follow-up at 12 months postdiagnosis showed no recurrence or complications. A systematic review was conducted, analyzing peer-reviewed studies from 1955 to 2024 in PubMed and EMBASE databases. Inclusion criteria focused on human studies reporting UAP, with data extracted on risk factors, diagnostic modalities, treatment strategies, and clinical outcomes. Statistical analyses included the Student's t test for continuous variables and the Pearson chi-square test for categorical variables. Out of 790 initially identified articles, 131 met inclusion criteria, comprising 144 patients with uterine artery UAP. Among these, 20 patients were pregnant, and 124 were nonpregnant. Comorbidities were more common in pregnant patients (55% vs 34.7%). Prior uterine manipulation occurred in 50% of pregnant and 90.3% of nonpregnant cases, with laparotomy and cesarean sections being most frequent. Vaginal bleeding was the most common symptom in nonpregnant patients (81.5%), while pain dominated in pregnant cases (85%). Imaging primarily involved ultrasound and angiography, combined with computed tomography (CT) in nonpregnant women (70% vs 35%) and MRI in pregnancy (70% vs 11.3%). Embolization was the main treatment (90% in pregnancy, 99% in nonpregnant), with few complications and no reported deaths. Statistical analysis showed a significant association in nonpregnant patients between vaginal bleeding and the need for transfusion (P<.05), as well as between bleeding and smaller UAP size (24.5 vs 32.3 mm, P<.05). UAP is rare and potentially serious. Vaginal bleeding is the most common presentation in nonpregnant patients, while pain is more frequent in pregnancy. Smaller UAPs were more likely to bleed in nonpregnant patients, suggesting rupture risk isn't solely size-dependent. Diagnostics can be performed by ultrasound, angiography, and CT, or in pregnancy, especially by MRI. Embolization is highly effective and remains the standard of care. Noninterventional management may be cautiously considered in hemodynamically stable patients with spontaneously thrombosed or nonperfused UAPs, though evidence of its effectiveness remains limited. An individualized, multidisciplinary management remains the key. Further data collection will help refine treatment strategies.\n\nID: 40890632\nTitle: Endometriosis and associations with risks of adverse pregnancy and perinatal outcomes: a case-control study in Egypt.\nAbstract: Endometriosis and its association with adverse pregnancy and perinatal outcomes have recently drawn attention, pointing to increased risks of repeated caesarean sections, the occurrence of preterm births, and stillbirths. This study included 25 pregnant women diagnosed with endometriosis and 25 pregnant women without endometriosis (control group). Maternal, fetal, and neonatal data were collected and compared between the endometriosis group and the control group concerning various maternal and neonatal parameters. Patients with endometriosis were slightly older, primipara (p\u2009=\u20090.048), and conceived using assisted reproductive technology (<\u20090.001**) than the control group. There were significant differences in blood loss between the endometriosis and control groups (p\u2009=\u20090.01). There are significant differences between both groups regarding placenta previa and blood loss in either vaginal delivery or caesarean section, post-partum hemorrhage. Severe deep infiltrating pelvis or ovarian endometriosis is considered a risk factor for the occurrence of maternal complications such as placenta previa, as well as fetal and perinatal complications. Additionally, a past history of pre-pregnancy surgical management of endometriosis was associated with a high risk of the occurrence of placenta previa.\n\nID: 40866312\nTitle: A Multifunctional Microneedle Patch Combined with Quercetin Nanoparticles for Local Drug Release Therapy and Wound Healing after Skin Tumor Surgery.\nAbstract: Melanoma, the most lethal form of skin cancer, is characterized by its highly aggressive and metastatic nature. Postoperative complications following melanoma resection often include elevated tumor recurrence rates, full-thickness skin defects, and bacterial infections. Consequently, preventing tumor recurrence and promoting skin wound healing are crucial considerations after tumor resection. This study developed hyaluronic acid-coated quercetin nanoparticles (HBQ NPs) modified with phenylboric acid, which has good stability under physiological conditions, pH response in acidic environments, and selectivity for A375 cells with CD44 receptor overexpression. A multifunctional microneedle (GHCQ) based on methacrylated gelatin (GelMA), methacrylated hyaluronic acid (HAMA), and carboxymethyl chitosan (CMCS) was prepared and functionalized by quercetin nanoparticles, endowing it with multiple functions such as antitumor, antioxidation, and antibacterial properties. In vitro release studies showed that GHCQ achieved sustained release of 61.96 \u00b1 1.33% quercetin within 21 days in a pH 5.0 environment, demonstrating its pH-responsive drug delivery ability. In vitro antitumor assays over 14 days demonstrated that GHCQ achieved an 83.27 \u00b1 2.08% inhibition rate against melanoma cells (A375). Additionally, GHCQ exhibited robust reactive oxygen species (ROS) scavenging capacity, excellent biocompatibility, and significant antimicrobial efficacy. Animal experiments revealed that GHCQ effectively prevented tumor recurrence while promoting angiogenesis, mitigating inflammation, and accelerating cutaneous regeneration during melanoma treatment in mice. Collectively, this multifunctional microneedle system demonstrates substantial potential for localized tumor wound therapy.\n\nID: 40775777\nTitle: CD44 signaling in skin wound healing and regeneration.\nAbstract: Post-natal skin wound healing results in scar formation. Current therapies for treating or preventing scarring, especially for hypertrophic scars (HTS), often yield unsatisfactory results. The development of HTS can result from dysfunction in the four overlapping phases of wound healing, particularly during the inflammatory phase. The injury induces upregulations of Cluster of Differentiation 44 (CD44) receptor and its primary and most specific ligand hyaluronic acid (HA). This suggests that CD44 signaling may play an important role in post-natal wound healing. In this comprehensive review, we summarize and compare, for the first time, the roles of CD44 signaling triggered by HA of different molecular weights in skin wound healing. Notably, we discuss a new paradigm to activate CD44's pro-regenerative properties in wound healing through the heavy chain-hyaluronan/Pentraxin 3 (HC-HA/PTX3), a complex that contains HA derived from human amniotic membrane. CD44 is involved throughout the four phases of skin wound healing: hemostasis, inflammation, proliferation, and remodeling. Importantly, CD44 signaling initiated by ligands may differently regulate the phenotypic and functional plasticity of various immune cells in wound inflammation. During wound remodeling, CD44 also exhibits immunoregulatory effects on keratinocytes and epithelial cells in re-epithelialization, vascular endothelial cells in wound angiogenesis, and fibroblasts involved in wound fibrosis. Finally, we discuss the roles of CD44 in wound regeneration and hair neogenesis, including how it governs stem cell biology to prevent or reverse scar formation. A better understanding of how to fine-tune CD44 signaling and identify its specific downstream effectors to modulate immune cell functions, inflammation, and regeneration will help shift the balance away from fibrotic scarring processes and open new therapeutic avenues for scarless regenerative wound healing.\n\nID: 40761421\nTitle: Perineal endometriosis on an episiotomy scar: diagnosis based on clinical, radiological, and hormonal criteria (case report).\nAbstract: Endometriosis is a chronic, non-cancerous gynecological disorder that is typically observed in women of fertile age. It describes the presence of functional endometrial components, glands and stroma outside the endometrial cavity, most often involving pelvic structures such as the ovaries, peritoneum, and uterine ligaments. Perineal endometriosis is a rare form of extrapelvic endometriosis, with an estimated incidence of between 0.3% and 1%. We report the case of a 36-year-old woman, gravida 1 para 1(G1P1), with a history of vaginal delivery and no known history of endometriosis, who presented with a painful mass located on the right perineal scar two years after undergoing a mediolateral episiotomy. The mass was associated with cyclical pain and significantly impaired quality of life. Clinical examination, combined with ultrasound and Magnetic Resonance Imaging (MRI), suggested the diagnosis of perineal endometriosis in the absence of other endometriotic lesions. As the patient declined surgery, hormonal therapy was initiated, resulting in marked symptom improvement at 8-month follow-up. Although histological confirmation was not obtained, the typical clinical presentation, evocative MRI features, and favorable response to hormonal therapy supported the diagnosis of perineal endometriosis. This under-recognized entity should be systematically considered in women of reproductive age presenting with cyclical perineal pain following episiotomy.\n\nID: 40731893\nTitle: The Role of Plant-Based Diets and Personalized Nutrition in Endometriosis Management: A Review.\nAbstract: Endometriosis is a chronic, estrogen-dependent inflammatory condition that affects multiple organ systems and significantly impairs the quality of life in women of reproductive age. While conventional hormonal therapies may alleviate symptoms of endometriosis, they are also frequently associated with intolerable side effects. As a result, there is growing interest in complementary, non-invasive strategies to support long-term disease management. This review explores the potential of plant-based diets and personalized nutrition as adjunctive approaches in endometriosis care. Plant-based dietary patterns, which are rich in antioxidants, phytochemicals, dietary fiber, and essential micronutrients, have been shown to reduce systemic inflammation, modulate estrogen activity, and alleviate pelvic pain. Additionally, the use of medicinal plants, such as curcumin and ginger, has demonstrated anti-inflammatory and anti-proliferative effects in preclinical studies. Moreover, identifying and addressing individual food sensitivities, particularly to gluten, dairy, or fermentable oligosaccharides, disaccharides, monosaccharides, and polyols, may improve gastrointestinal and inflammatory symptoms in susceptible individuals. Future research should focus on high-quality clinical trials and integrative care models to evaluate the long-term efficacy, safety, and sustainability of these individualized nutritional interventions in the holistic management of endometriosis.\n\nID: 40691413\nTitle: Robotic single port versus robotic multiple port transvaginal orifice transluminal endoscopic surgery hysterectomy: a comparison of surgical outcomes.\nAbstract: To evaluate the feasibility and safety of robotic single-port transvaginal natural orifice transluminal endoscopic surgery (RSP-vNOTES) compared to robotic multi-port vNOTES (RMP-vNOTES) for hysterectomy and associated procedures. 383 patients were retrospectively analyzed. Among the participants, 291 underwent RMP-vNOTES hysterectomy and 92 underwent RSP-vNOTES hysterectomy. The RSP-vNOTES group had a lower median BMI (26 vs. 29\u00a0kg/m2, p\u2009=\u20090.02), fewer patients with prior vaginal delivery (32% vs. 46%, p\u2009=\u20090.02), and lower median uterine weight (92 vs. 122\u00a0g, p\u2009=\u20090.02). Regarding additional surgical procedures performed, the RSP-vNOTES group had a higher proportion of endometriosis excision-related interventions (lysis of adhesions, endometriosis excision, ovarian cystectomy, appendectomy, bowel shaving, and bowel oversew, all p\u2009<\u20090.05). Multiple linear regression analysis was conducted to adjust for these variables. After adjustment, no significant differences were observed between the groups in total operative time, port placement time, hysterectomy time, estimated blood loss, or conversion rate. No significant differences existed in postoperative pain or complications. In total, three conversions to abdominal robotics occurred (0.8%), all due to complex endometriosis. Robotic vNOTES enhances the performance of vaginal surgeries by leveraging the established advantages of robotic technology with the minimally invasive advantage of vaginal surgery. Both RSP-vNOTES and RMP-vNOTES are effective and safe, but RSP-vNOTES offering logistical and ergonomic benefits while facilitating increased complexity of procedures, particularly endometriosis excision. Overall, RSP-vNOTES is an efficient approach for advanced gynecologic surgery.\n\nID: 40639263\nTitle: Efficacy of Cyclosporin A and Tacrolimus in the Treatment of Endometriosis of Rats.\nAbstract: The molecular and cellular mechanisms underlying endometriosis are still under investigation. Cyclophilin A (CypA) is an inflammatory marker secreted by various types of cells in an inflammatory condition. During inflammation, CypA exacerbates the inflammatory response by activating calcineurin signaling, which increases cytokine secretion and tissue degradation in the inflammatory region. This study investigated the effect of inhibiting calcineurin signaling in treating endometriosis in rats. Thirty-two albino Wistar rats were used in this study. All rats were divided into three groups: cyclosporin A (n = 10), tacrolimus (n = 10) and a control group (n = 12). The cyclosporin A (CsA) group received two intraperitoneal doses two weeks apart, and the tacrolimus group received the same two doses intravenously, also two weeks apart. All studies lasted eight weeks. The processed endometrial tissues were cut in half and embedded in paraffin. Histological sections (5 \u00b5m) were stained with Ki-67, Bcl-2, caspase-3 and VEGF. The endometriotic focus size was 204.7 \u00b1 153.4 mm3, 71.9 \u00b1 85.4 mm3, and 30.6 \u00b1 36.7 mm3 in the control, CsA, and tacrolimus groups, respectively. Compared to the control group, the endometriotic focus size was smaller in the CsA and tacrolimus groups (p = 0.002). Microscopically, Ki-67 (p = 0.010) and VEGF (p = 0.007) immunoreactivity were lower in the CsA and tacrolimus groups than in controls. The inhibition of calcineurin signaling with CsA or tacrolimus treatment causes regression of the endometriotic focus by decreasing endometriotic cell proliferation and angiogenesis in ectopic endometriotic tissue.\n\nID: 40592115\nTitle: Multifunctional silver nanoclusters with hyaluronic acid for dual-targeted tumor imaging and ROS-mediated therapy.\nAbstract: Despite their potential in cancer theranostics, silver nanoparticles (Ag NPs) face significant clinical translation challenges, including polydispersity, weak fluorescence emission, and suboptimal biocompatibility. To overcome these challenges, we introduce Ag@PEG2000-HA nanoclusters (NCs), novel silver-based NCs developed through a sequential functionalization process using polyethylene glycol (PEG) and hyaluronic acid (HA). The HA-induced stabilization enlarges nanocluster cores and promotes ligand-metal charge transfer, synergizing with size-dependent aggregation-induced emission (AIE) effect to amplify fluorescence. These developed nanoconstructs showcase enhanced theranostic capabilities, featuring strong near-infrared (NIR) fluorescence for live tumor imaging and reactive oxygen species (ROS)-enabled mitochondrial targeting to induce cancer cell apoptosis selectively. Systematic evaluations, both in vitro and in vivo, confirmed significant tumor growth inhibition, increased survival rates, and a positive biosafety profile. The dual-targeting approach, leveraging the enhanced permeability and retention (EPR) effect alongside HA-mediated CD44 interaction, ensures precise tumor targeting and reduces off-target effects. Additionally, the nanoclusters showed exceptional stability, extended blood circulation, and resistance to macrophage phagocytosis, thereby enhancing their therapeutic effectiveness. Detailed mechanistic studies showed that Ag@PEG2000-HA NCs trigger apoptosis via ROS production and mitochondrial disruption, and concurrently reduce the expression of key tumor-associated proteins (CD31, Ki-67, and MMP9), inhibiting angiogenesis, proliferation, and metastasis. This research establishes a multifunctional nanoplatform bridging diagnostic imaging and therapy, opening new avenues for precision oncology. The findings provide fundamental insights into the design principles of cluster-based theranostic nanomaterials, paving the way for their clinical translation in cancer treatment.\n\nID: 40508002\nTitle: Endometriosis: An Immunologist's Perspective.\nAbstract: Endometriosis, a complex inflammatory disease, affects a significant proportion of women of reproductive age, approximately 10-15%. The disease involves the growth of endometrial glands and stroma outside the uterine cavity, leading to tissue remodeling and fibrosis. Hormonal imbalances, accompanied by local and general inflammation and pain, are key features of endometriosis. Endometriotic lesions are associated with the overproduction of cytokines, metalloproteinases, prostaglandins, reactive oxygen radicals, and extracellular vesicles. Genetic predisposition and cytokine gene polymorphisms have been documented. Macrophages, dendritic cells, mast cells, Th1 in the early phase, Th2 in the late phase, and T regulatory cells play a crucial role in endometriosis. Reduced NK cell function and impaired immune vigilance contribute to endometrial growth. The strong inflammatory condition of the endometrium poses a barrier to the proper implantation of the zygote, contributing to the infertility of these patients. Cytokines from various cell types vary with the severity of the disease. The role of microbiota in endometriosis is still under study. Endometriosis is associated with autoimmunity and ovarian cancer. Hormonal treatments and surgery are commonly used; however, recent interest focuses on anti-inflammatory and immunomodulatory therapies, including cytokine and anti-cytokine antibodies. Modulating the immune response has proven critical; however, more research is needed to optimize treatment for these patients.\n\nID: 40462414\nTitle: Comparison of pregnancy outcomes and vaginal microbiota in women with endometriosis undergoing frozen embryo transfer using letrozole combined with HMG versus hormone replacement therapy with GnRH-a pretreatment.\nAbstract: This study investigated differences in reproductive outcomes and vaginal microbiota profiles between two endometrial preparation protocols-letrozole (LE) combined with human menopausal gonadotropin (HMG) and hormone replacement therapy (HRT) with gonadotropin-releasing hormone agonist (GnRH-a) pretreatment-in women with endometriosis undergoing frozen embryo transfer (FET). Following 1\u22361 propensity score matching, a total of 770 FET cycles were analyzed. No statistically significant differences were observed in live birth rates or clinical pregnancy rates between the two groups. However, the LE + HMG group showed a nonsignificant trend toward a lower miscarriage rate (13.7% vs. 19.8%, P = 0.070), as well as lower observed rates of cesarean delivery (64.9% vs. 75.4%, P = 0.020) and hypertensive disorders of pregnancy (4.8% vs. 10.1%, P = 0.039). Previous evidence suggests an association between GnRH-a treatment and reproductive tract microbiota composition. Given the clinical and ethical constraints of endometrial sampling during FET, vaginal microbiota was evaluated as a non-invasive indicator of lower reproductive tract microbial composition. In the prospective arm, vaginal samples from 55 women in the LE + HMG group and 50 in the GnRH-a HRT group were analyzed using 16S rRNA sequencing and droplet digital PCR. While no significant differences were observed in Lactobacillus or Gardnerella abundance, the GnRH-a HRT group showed higher relative abundances of several low-abundance taxa, such as Escherichia-Shigella, Limosilactobacillus, and Staphylococcus. In conclusion, although both protocols achieved comparable live birth outcomes, the LE + HMG regimen was associated with lower rates of cesarean delivery and hypertensive disorders of pregnancy, while the two protocols exhibited differences in several low-abundance vaginal bacterial taxa. However, longitudinal studies incorporating baseline and repeated sampling are needed to clarify temporal relationships and causality.\n\nID: 40450431\nTitle: Unveiling the role of extracellular vesicles in reproductive success and uterine diseases - a systematic review.\nAbstract: Extracellular vesicles play a key role in endometrium-embryo communication under both physiological and pathological conditions. This systematic review includes 49 studies that highlight how extracellular vesicles help optimize embryo implantation conditions, and 39 evidencing extracellular vesicle contributions to the pathogenesis of uterine diseases, such as endometriosis, endometrial cancer, recurrent implantation failure (RIF), adenomyosis, uterine leiomyoma and endometritis. Under normal physiological conditions, the protein and microRNA cargo of uterine extracellular vesicles regulated endometrial receptivity, maternal tolerance and embryo development, adhesion and implantation. In endometriosis, extracellular vesicles contributed to pathophysiology via angiogenesis, fibrosis, inflammation, lesion progression and reproduction. Extracellular vesicles promoted endometrial cancer progression and metastasis. In RIF, extracellular vesicles hindered embryo invasiveness, migration, survival and implantation. extracellular vesicles contributed to the progression of adenomyosis, negatively impacting decidualization, implantation and embryo development, whereas in uterine leiomyoma and endometritis, extracellular vesicles affected endometrial receptivity, immune tolerance, blastocyst development, migration and invasion. Overall, uterine extracellular vesicles are key mediators of the endometrium-embryo communication required for successful pregnancy. An altered extracellular vesicle cargo from women with uterine disorders may promote disease progression and associated infertility. Therefore, extracellular vesicles represent potential biomarkers and therapeutic targets for uterine disorders.\n\nID: 40093416\nTitle: Extracellular vesicles in endometrial-related diseases: role, potential and challenges.\nAbstract: Endometrial dysfunction underlies many common gynecologic disorders, such as endometriosis, endometrial cancer, intrauterine adhesions, and endometritis, which affect many women around the world. Extracellular vesicles play an important role in the pathophysiologic process of endometrial-related diseases. Extracellular vesicles are released by cells, which usually act as a form of intercellular communication, affecting biological processes such as fibrosis, angiogenesis, cell proliferation, and inflammatory responses by transferring their own proteins, lipids, RNA transcripts, and DNA for messaging, and play a key role in physiological dynamic homeostasis and disease development. This review combines the studies of the last decade, using the sub-description method to introduce the application of different sources of extracellular vesicles in the diagnosis and treatment of related diseases, and discusses the challenges faced by extracellular vesicles in the diagnostic and therapeutic application of endometriosis-related diseases, with the aim of contributing to our understanding of the mechanism of action of extracellular vesicles and their therapeutic roles, so as to provide a reference for the development of endometriosis-related diseases, as well as their prognosis and treatment.\n\nID: 42427730\nTitle: Extracellular Vesicles Mediate Activation and Trafficking of Splenic Immune Cells to the Heart Post-Myocardial Infarction.\nAbstract: Myocardial infarction (MI) triggers splenic immune cell trafficking to the heart. Vehicles that carry these signals and mediate this crosstalk are unknown. We hypothesize that extracellular vesicles (EVs) released post-MI mediate splenic immune trafficking to the heart. Mice were treated daily with an EV biogenesis inhibitor (GW4869) or vehicle. Splenic/cardiac immune cells were assessed at 3d while survival, cardiac function, hypertrophy, and fibrosis were evaluated at 8w post-MI. Plasma EVs from 1d MI mice or from the hearts that underwent MI/sham in a Langendorff system induced splenic immune trafficking to the heart within 3d and systolic dysfunction at 8w in na\u00efve mice. GW4869 i) inhibited splenic regression, ii) increased splenic retention of neutrophils, monocytes, dendritic cells (DCs), and CD4+ T-cells, iii) decreased cardiac gene expression of proinflammatory cytokines/chemokines, and iv) decreased trafficking of immune cells to the hearts at 3d post-MI, and iii) improved systolic function and attenuated hypertrophy at 8w post-MI. MI EVs accumulated in the spleen and promoted egress of matured splenic immune cells upon administration to na\u00efve mice. Cardiac pro-inflammatory cytokines/chemokines expression and CCR2+MHC-IIhi infiltrating macrophages, CD11c+ DCs, and CD4+ and CD4+TNF\u03b1+ T-cell levels were also increased in na\u00efve mice at 3d post-injection. Importantly, transfer of MI EVs for 2 days induced systolic dysfunction, cellular hypertrophy, and fibrosis in na\u00efve mice at 8 w post-injection. DCs process MI EVs for T-cells activation. EVs mobilize splenic immune cells to the heart post-MI and their inhibition can subdue inflammatory tissue-damage to promote healing post-MI.\n\nID: 42421776\nTitle: Self-organizing three-dimensional dermal papilla cell spheroids yield therapeutic extracellular vesicles that target hypertrophic scar regression via the miR-26a-5p/CCNE2 axis.\nAbstract: Hypertrophic scarring remains a critical challenge in regenerative medicine because of the limited efficacy of current antifibrotic therapies. Although dermal papilla cells (DPCs) exhibit intrinsic scar-inhibitory potential, their therapeutic utility is constrained by rapid replicative senescence and poor scalability in traditional monolayer cultures, necessitating innovative strategies to enhance cellular functionality and manufacturing feasibility. A self-feeder layer 3D (SFL-3D) platform was established to reprogram primary human DPCs into rejuvenated three-dimensional DPC (tdDPC) spheroids via autocrine-paracrine signalling activation. tdDPC-derived extracellular vesicles (tdDPC-EVs) were isolated from culture supernatants by differential centrifugation. The antifibrotic effects of tdDPC-EVs were systematically evaluated using human scar fibroblasts through scratch wound healing assays, CCK-8 proliferation assays, and fibrotic marker analysis [Western blotting and immunofluorescence staining for \u03b1-smooth muscle actin (\u03b1-SMA) and collagen I]. Bioinformatics was used to predict key pathways involved in hypertrophic scar (HS) pathogenesis, whereas gain/loss-of-function studies investigated the miR-26a-5p/CCNE2 regulatory axis. Therapeutic validation was performed in a rabbit ear hypertrophic scar model with histopathological and molecular profiling. Compared with conventional 3D cultures, the SFL-3D system demonstrated superior proliferative support, enabling stable tdDPC expansion beyond 10 passages while maintaining high viability and enhanced EV biogenesis. miR-26a-5p-enriched tdDPC-EVs attenuated fibrosis through two mechanisms: (1) silencing CCNE2 to block PI3K/AKT-driven collagen overproduction and (2) suppressing \u03b1-SMA\u2009+\u2009myofibroblast differentiation. In the rabbit ear HS model, tdDPC-EV administration reduced the scar elevation index and restored the collagen I/III ratio to near-physiological levels. This study positions tdDPC-EVs as a scalable acellular therapy that overcomes the replicative senescence and manufacturing limitations of cellular approaches. The antiscarring efficacy of these EVs, which is mediated by the miR-26a-5p/CCNE2/PI3K/AKT axis, highlights their clinical potential as precision-targeted strategies for hypertrophic scar management. The SFL-3D platform further provides a translatable framework for EV-based regenerative therapeutics.\n\nID: 42223671\nTitle: Reelin level in serum-derived extracellular vesicles predicts regression of M2BPGi-defined liver fibrosis following hepatitis C virus eradication by direct-acting antiviral agents.\nAbstract: We investigated serum-derived extracellular vesicle (EV)-associated proteins as predictors of liver fibrosis (LF) regression following sustained virological responses (SVR) in individuals with chronic hepatitis C (CHC) managed using direct-acting antiviral (DAA) therapy. We retrospectively analyzed 107 CHC patients with pretreatment Mac-2 binding protein glycosylation isomer (M2BPGi) levels\u2009\u2265\u20092.0 cut-off index (COI). Two years after the end of treatment (EOT), participants were grouped according to the M2BPGi levels: regression group (M2BPGi\u2009<\u20091.76 COI) and non-regression group (M2BPGi\u2009\u2265\u20091.76 COI). Twelve patients were selected for the discovery cohort, where comprehensive protein profiling of serum-derived EVs was performed at 12-24\u00a0weeks post-EOT using quantitative mass spectrometry for label-free quantification. The remaining 95 patients formed the validation group, in which the identified EV proteins were further assessed via protein quantification using parallel reaction monitoring. Reelin (RELN) and oncoprotein-induced transcript 3 (OIT3) protein had potential role as predictors of fibrosis regression in both groups. Multivariate analysis incorporating clinical parameters indicated that levels of RELN and OIT3 were associated with fibrosis regression (odds ratio [OR]\u2009=\u20091.510; P\u2009=\u20090.022 for log2 RELN, and OR\u2009=\u20090.297; P\u2009=\u20090.001 for log2 OIT3). In cases with advanced fibrosis (baseline M2BPGi\u2009\u2265\u20093.3 COI), RELN showed a borderline significant result (OR\u2009=\u20091.550; P\u2009=\u20090.050 for log2 RELN). Serum-derived EV levels of RELN show promise as predictor of LF regression in CHC patients following SVR.\n\nID: 41492018\nTitle: Analysis of BAL extracellular vesicles unveils NF-\u03baB activation at the onset of chronic lung allograft dysfunction.\nAbstract: The onset of chronic lung allograft dysfunction (CLAD) represents the greatest long-term challenge in lung transplantation (LT). Here we aimed to identify early molecular signals of CLAD by analyzing the effects of bronchoalveolar lavage (BAL)-derived extracellular vesicles (EVs) on airway cells and validating these findings in patient lung tissues. In our BAL biobank, we identified 13 LT patients with a BAL sample at CLAD diagnosis and 13 patients with a stable graft function and a BAL sample obtained at least 12 months post LT (Ctrl). All patients were then followed for at least 18 months. EVs were isolated, immunophenotyped, and co-cultured with airway cells. The cells' transcriptome and proteome were profiled. Selected targets were validated by immunohistochemistry. Logistic regression and survival analyses were performed for prediction of CLAD progression. During follow-up, 7 CLAD patients experienced allograft dysfunction aggravation, and one control developed CLAD. CLAD patients showed more EVs originating from epithelial cells and leukocytes than stable LT recipients. Exposure of airway cells to CLAD-EVs led to the up-regulation of p70S6K and canonical NF-\u03baB signaling, altering their intracellular and extracellular proteome. Activation of NF-\u03baB was also detected at the onset of CLAD in transbronchial biopsies and BAL cytology, and it persisted throughout the progression to end-stage CLAD. RelA overexpression was associated with poorer graft performance and worse outcomes. RelA-driven NF-\u03baB activation is a key factor in the development of CLAD by promoting persistent inflammation. This pathway may be a promising therapeutic target to improve long-term graft survival after LT.\n\nID: 41072000\nTitle: Hepatocyte-derived extracellular vesicles promote endothelial dedifferentiation in chronic liver disease through the miR-153-3p-pyroptosis axis.\nAbstract: Liver cells communicate paracrinally through extracellular vesicles (EVs). This study investigated the role of microRNAs (miRNAs) embedded in hepatocyte-derived EVs (hepEVs) modulating endothelial cell dedifferentiation in chronic liver disease. EVs were purified from primary hepatocytes isolated from healthy (CT) and cirrhotic (CH) livers in both humans and rats. CT-rats were intravenously treated with fluorescence-labeled hepEVs-CT or hepEVs-CH (200\u00a0\u03bcg/d, 3\u00a0d, n=10/group) to assess biodistribution and LSECs phenotype. miRNA profiling of human hepEVs-CH was validated in rat models, and commonly altered miRNAs were overexpressed in CT-LSECs. Gene dysregulation was analyzed in primary CH-LSECs and liver tissues from rats and humans with cirrhosis, as well as CT-LSECs treated with miRNA-specific upregulated hepEVs. CH-rats were treated with the Caspase-1 inhibitor VX-765 (15\u00a0mg/kg/d, 10 doses, n=11/group) to evaluate its effects on liver function, hemodynamics, and endothelial phenotype. In vivo, hepEVs-CH accumulated predominantly in LSECs, disrupting genes involved in fibrosis, inflammation, and cell death, while enhancing the von Willebrand factor expression and altering eNOS activity. Profiling of human hepEVs-CH revealed 37 dysregulated miRNAs, with miR-200a-3p and miR-153-3p validated in rat hepEVs-CH. Transfection of miR-153-3p into CT-LSEC dysregulated 771 genes involved in inflammation and cell death, particularly pyroptosis. Increased active Caspase-1 and Gasdermin-D expression was observed in human and rat cirrhotic liver tissue, as well as in CT-LSEC treated with miR-153-3p-hepEVs, indicating enhanced pyroptosis. In vivo, VX-765 treatment reduced hepatic pyroptosis, improving endothelial phenotype and portal hypertension. HepEVs-derived miRNAs, particularly miR-153-3p, contribute to endothelial dysfunction in chronic liver disease by triggering pyroptosis through a paracrine mechanism. Inhibiting Caspase-1 may provide a novel therapeutic approach to mitigate endothelial dysfunction in chronic liver disease.\n\nID: 40791857\nTitle: Restoration of tendon repair microenvironment by grapefruit exosome-loaded microneedle system for tendinopathy therapy.\nAbstract: Tendinitis repair remains challenging due to the limited self-renewal capacity of tenocytes and persistent inflammatory microenvironment. Conventional therapies remain limited by systemic drug toxicity and fail to coordinate immunomodulation with matrix remodeling. Plant-derived extracellular vesicles have demonstrated tissue repair potential owing to their unique bioactive components and exceptional cross-species compatibility. Nevertheless, their therapeutic role in tendon matrix regeneration remains underexplored. Here, we developed a grapefruit-derived exosome-loaded microneedle patch (MN@GF-Exos) to synergistically restored tendon structure and functions. Grapefruit-derived exosomes (GF-Exos) were loaded into dissolvable hyaluronic acid microneedles (MNs) for sustained release. GF-Exos reversed oxidative stress in tenocytes, enhancing cellular proliferation and migration, restoring collagen I synthesis, and polarizing macrophages toward M2-repair phenotypes. Transcriptomics revealed GF-Exos modulated cytokine-cytokine receptor interactions, suppressing inflammation-related pathways and activating ECM organization genes. In collagenase-induced tendinopathy mice, MN@GF-Exos enhanced gait recovery and extracellular matrix remodeling. Histology confirmed reduced fibrosis without ectopic ossification. Systemic safety was validated by unchanged organ histology and within-normal-limits serum biomarkers. This dual-functional system leverages plant exosomes' multi-component synergy and MN's spatiotemporal control, offering a translatable strategy for chronic tendon regeneration.\n\nID: 40461474\nTitle: Clinical investigation on nebulized human umbilical cord MSC-derived extracellular vesicles for pulmonary fibrosis treatment.\nAbstract: Mesenchymal stromal cell-derived extracellular vesicles (MSC-EVs) are recognized as a promising strategy for cell-free therapy, however, their therapeutic role in pulmonary fibrosis remains unrevealed. Here, we report the safety and efficacy of MSC-EVs from human umbilical cord (hUCMSC-EVs) evaluated in mouse models and pulmonary fibrosis patients. We established a rigorous system to produce high-quality of hUCMSC-EVs, characterized by miRNA, protein, and metabolite profiles. When administered via nebulization, hUCMSC-EVs predominantly accumulated in murine lungs and ameliorated bleomycin-induced pulmonary fibrosis, with increased survival rate (from 20% to 80%), restored lung volume, and attenuated injury severity accompanied by elevated oxyhemoglobin saturation and improved pulmonary function evaluations. We performed a phase l clinical trial involving twenty-four patients in a randomized, single-blind, and placebo-controlled study to treat pulmonary fibrosis (MR-46-22-004531, ChiCTR2300075466). All participants tolerated the nebulized hUCMSC-EVs well, with no serious adverse events. Patients receiving the combined therapy of nebulized hUCMSC-EVs and routine treatment demonstrated significant improvements in both lung function indices (forced vital capacity and maximal voluntary ventilation) and respiratory health status (as measured by the Saint George's Respiratory Questionnaire and Leicester Cough Questionnaire. Overall, patients upon the additional therapy with nebulized hUCMSC-EVs gained significant benefits compared with those accepted only routine treatment. Remarkably, two patients with advanced post-inflammatory pulmonary fibrosis exhibited clinically significant regression on serial CT scans after hUCMSC-EVs therapy. These findings suggest that nebulized hUCMSC-EVs could be used as a promising therapeutic strategy for treating pulmonary fibrosis diseases.\n\nID: 40176849\nTitle: Extracellular vesicles derived microRNAs as non-invasive markers of liver fibrosis in chronically infected HCV patients: a pilot study.\nAbstract: Extracellular vesicles (EVs) are an increasingly promising tool for liquid biopsy in liver diseases. Hepatitis C Virus (HCV) infection, alone or together with Human Immunodeficiency Virus (HIV) infection significantly impacts on the microRNA (miRNA) EVs content resembling chronic hepatitis C (CHC) progression. The objective of the study was to delve into the intricate EVs-miRNA profiles in CHC patients with different liver fibrosis stages, aiming to pinpoint non-invasive markers capable of distinguishing significant fibrosis. Plasma EV-miRNAs from 50 CHC patients (HCV+ and HCV+/HIV+) stratified in no significant (F\u00a0<\u00a02) and significant (F\u00a0\u2265\u00a02) fibrosis, were massively sequenced. General linear models (GLM) were used to identify significantly differential expressed (SDE) miRNAs according to liver fibrosis stages (F\u00a0\u2265\u00a02 and F\u00a0<\u00a02). Dysregulated biological pathways were subsequently analyzed in silico for the following groups: i) all patients; ii) HCV+; and iii) HCV+/HIV+. Multiple-ordered logistic regression analysis was performed to develop a score to identify F\u00a0\u2265\u00a02 cases. The diagnostic potential of both the SDE miRNAs and the developed score was assessed using ROC curve analysis. With respect to all CHC patients, two SDE miRNAs (hsa-miR-122-5p and hsa-miR-92a-3p) were identified which regulate genes related to cytoskeleton organization. Regarding their diagnostic performance to discriminate F\u00a0\u2265\u00a02, both miRNAs individually demonstrated acceptable diagnostic values. However, their combined use in a new score enhanced their diagnostic performance (AUROC\u00a0=\u00a00.833). In the HCV+\u00a0subgroup, 8 SDE miRNAs (hsa-miR-122-5p, hsa-miR-320c, hsa-miR-3615, hsa-miR-320a-3p, hsa-miR-374b-5p, hsa-let-7a-3p, hsa-miR-199a-5p, hsa-miR-142-5p), which regulate macrophage activity and cell growth/death regulation, were recognized. Among them, hsa-miR-3615 displayed the highest diagnostic performance to discriminate F\u00a0\u2265\u00a02 (AUROC\u00a0=\u00a00.936). With respect to HCV+/HIV+, 18 SDE miRNAs (hsa-miR-4508, hsa-miR-122-5p, hsa-miR-451a, hsa-miR-1290, hsa-miR-1246, hsa-miR-107, hsa-miR-15b-5p, hsa-miR-194-5p, hsa-miR-22-5p, hsa-miR-20b-5p, hsa-miR-142-5p, hsa-miR-328-3p, hsa-miR-335-3p, hsa-miR-125a-5p, hsa-miR-423-3p, hsa-let-7d-3p, hsa-miR-128-3p, hsa-miR-10a-5p) were recognized that regulate RNA silencing processes. In this case, hsa-miR-423-3p and hsa-miR-128-3p showed outstanding diagnostic performances (AUROC > 0.900). Distinct EVs-miRNA profiles were identified in patients with varying liver fibrosis stages, both in the overall CHC cohort and within HCV+ and HCV+/HIV+\u00a0subgroups. These specific miRNA signatures would allow the elucidation of potential mechanisms involved in clinical evolution and identification of specific biomarkers of unfavorable progression, plausible to be used in a diagnostic panel. Furthermore, the developed score demonstrates the ability to discriminate within the CHC group those individuals with significant fibrosis regardless of their HIV infection status.\n\nID: 39502438\nTitle: Extracellular vesicle mimetics engineered from mesenchymal stem cells and curcumin promote fibrosis regression in a mouse model of thioacetamide-induced liver fibrosis.\nAbstract: Recent research suggests that advanced liver fibrosis could be reversed, but the therapeutic agents needed for the prevention of liver fibrosis remain to be elucidated. The beneficial effects of mesenchymal stem cells (MSCs) and MSC-derived extracellular vesicles (EVs) on liver fibrosis have been reported. However, the large-scale production of MSC-EVs remains challenging. The present study investigated the therapeutic effects of mouse MSC-derived EV mimetics (MEVMs) in combination with curcumin (antifibrotic compound) using a mouse model of thioacetamide-induced liver fibrosis. MEVMs were prepared through the serial extrusion of MSCs. These MEVMs were similar in size and morphology to the EVs. The biodistribution study showed that fluorescently labeled MEVMs predominantly accumulated in the liver. The establishment of liver fibrosis was confirmed via increased collagen (histology), liver fibrosis score, \u03b1-smooth muscle actin (\u03b1-SMA), and vimentin proteins levels. Treatment with MEVMs, curcumin, or their combination decreased the amount of collagen in liver tissues, with the antifibrotic effects of MEVMs being further confirmed by the liver fibrosis score. All treatments decreased the expression of collagen 1\u03b1, \u03b1-SMA, and vimentin. MEVMs showed superior effects than curcumin. Thus, MSC-derived EVMs could be a potential alternative for the treatment of liver fibrosis.\n\nID: 38939072\nTitle: Plasma extracellular vesicle proteins as promising noninvasive biomarkers for diagnosis of idiopathic pulmonary fibrosis.\nAbstract: High-resolution computed tomography (HRCT) imaging is critical for diagnostic evaluation of Idiopathic Pulmonary Fibrosis (IPF). However, several other interstitial lung diseases (ILDs) often exhibit radiologic pattern similar to IPF on HRCT making the diagnosis of the disease difficult. Therefore, biomarkers that distinguish IPF from other ILDs can be a valuable aid in diagnosis. Using mass spectrometry, we performed proteomic analysis of plasma extracellular vesicles (EVs) in patients diagnosed with IPF, chronic hypersensitivity pneumonitis, nonspecific interstitial pneumonitis, and healthy subjects. A five-protein signature was identified by lasso regression and was validated in an independent cohort using ELISA. The five-protein signature derived from mass spectrometry data showed an area under the receiver operating characteristic curve of 0.915 (95%CI: 0.819-1.011) and 0.958 (95%CI: 0.882-1.034) for differentiating IPF from other ILDs and from healthy subjects, respectively. Stepwise backwards elimination yielded a model with 3 and 2 proteins for discriminating IPF from other ILDs and healthy subjects, respectively, without compromising diagnostic accuracy. In summary, we discovered and validated EV protein biomarkers for differential diagnosis of IPF in independent cohorts. Interestingly, the biomarker panel could also distinguish IPF and healthy subjects with high accuracy. The biomarkers need to be evaluated in large prospective cohorts to establish their clinical utility.\n\nID: 38739200\nTitle: MicroRNA-223-3p levels in serum-derived extracellular vesicles predict regression of M2BPGi-based liver fibrosis after hepatitis C virus eradication by direct-acting antiviral agents.\nAbstract: We retrospectively investigated microRNA (miRNA) levels in serum-derived extracellular vesicles (EVs) as predictive indicators for regression of liver fibrosis, after achievement of a sustained virological response (SVR) by direct-acting antiviral (DAA) therapy for chronic hepatitis C (CHC). The study subjects were recruited from a historical cohort of 108 CHC patients whose pretreatment serum Mac-2-binding protein glycosylation isomer (M2BPGi) levels were\u2009\u2265\u20092.0 cut-off index (COI). We classified patients with M2BPGi levels\u2009<\u20091.76 and\u2009\u2265\u20091.76 COI at 2 years after the end of treatment (EOT) into the regression and non-regression groups, respectively. Eleven of the patients were assigned to the discovery set, and we comprehensively investigated the miRNAs contained in serum-derived EVs at 24\u00a0weeks after the EOT (EOT24W), using RNA sequencing. The remaining 97 patients were assigned to the validation set, and reproducibility was verified by quantitative real-time PCR. Through analysis of the discovery and validation sets, we identified miR-223-3p and miR-1290 as candidate predictors. Subsequently, we analyzed various clinical data, including these candidate miRNAs. Multivariate analyses revealed that the levels of miR-223-3p at EOT24W were significantly associated with regression of M2BPGi-based liver fibrosis (Odds ratio: 1.380; P\u2009=\u20090.024). Consistent results were obtained, even when the serum M2BPGi levels were aligned by propensity score matching and in patients with advanced M2BPGi-based liver fibrosis (pretreatment M2BPGi levels\u2009\u2265\u20093.3 COI). The miR-223-3p level in serum-derived EVs at EOT24W is a feasible predictor of regression of M2BPGi-based liver fibrosis after achievement of an SVR by DAA therapy.\n\nID: 38716677\nTitle: An Indocyanine Green-Based Nanocluster for Imaging Orthodox Endometriosis Lesions with Negative Contrast.\nAbstract: Indocyanine green (ICG), as the sole near-infrared dye FDA-approved, is limited in biomedical applications because of its poor photostability, lack of targeting, and rapid removal in vivo. Herein, we presented a nanoformulation of poly-l-lysine-indocyanine green-hyaluronic acid (PIH) and demonstrated that it can image orthodox endometriosis (EM) lesions with a negative contrast. The PIH nanocluster, with an average diameter of approximately 200 nm, exhibited improved fluorescence photostability and antioxidant ability compared to free ICG. In the in vivo imaging, EM lesions were visualized, featuring apparent voids and clear boundaries. After colocalizing with the green fluorescent protein, we concluded that the contrast provided by PIH peaked at 4 h postinjection and was observable for at least 8 h. The negative contrast, clear boundaries, and enhanced observable time might be due to the low permeation of PIH to lesions and the enhanced retention on the surfaces of lesions. Thus, our findings suggest an ICG-based nanoprobe with the potential to diagnose abdominal diseases.\n\nID: 38703918\nTitle: Hyaluronic acid modified extracellular vesicles targeting hepatic stellate cells to attenuate hepatic fibrosis.\nAbstract: Transforming growth factor-beta1 (TGF-\u03b21) plays a pivotal role in promoting hepatic fibrosis, pirfenidone (PFD) could inhibit TGF-\u03b21 signaling pathway to alleviate hepatic stellate cells (HSC) activation mediated hepatic fibrosis. The targeting delivery strategy of PFD to hepatic stellate cells is a challenge. Extracellular vesicles (EVs), cell-derived membranous particles are intraluminal nano-vesicles that play a vital role in intercellular communication, they also be considered as an ideal nano-carrier. In this study, we developed a target strategy to deliver PFD to HSC with CD44 over-expression by EVs, hyaluronic acid (HA) modified DSPE-PEG2000 endows the active targeting ability of activated HSCs to PFD-loaded EVs. In both rat hepatic stellate cell line HSC-T6 and rat hepatocyte cell line BRL, HA@EVs-PFD demonstrated the capacity to down-regulate the expression of collagen-synthesis-related proteins and showed superior inhibition efficacy of HSC-T6 activation compared to free PFD. In hepatic fibrosis model, 4 weeks of HA@EVs-PFD treatment resulted in a reduction in liver collagen fibers, significant improvement in hepatic cell morphology, and amelioration of hepatic fibrosis. HA@EVs-PFD, as a drug delivery system that effectively targets and inhibits activated HSCs to treat hepatic fibrosis, holds promise as a potential therapeutic agent against hepatic fibrosis.\n\nID: 38655426\nTitle: 3D bioprinted aged human post-infarct myocardium tissue model.\nAbstract: Fibrotic tissue formed after myocardial infarction (MI) can be as detrimental as MI itself. However, current in vitro cardiac fibrosis models fail to recapitulate the complexities of post-MI tissue. Moreover, although MI and subsequent fibrosis is most prominent in the aged population, the field suffers from inadequate aged tissue models. Herein, an aged human post-MI tissue model, representing the native microenvironment weeks after initial infarction, is engineered using three-dimensional bioprinting via creation of individual bioinks to specifically mimic three distinct regions: remote, border, and scar. The aged post-MI tissue model is engineered through combination of gelatin methacryloyl, methacrylated hyaluronic acid, aged type I collagen, and photoinitiator at variable concentrations with different cell types, including aged human induced pluripotent stem cell-derived cardiomyocytes, endothelial cells, cardiac fibroblasts, and cardiac myofibroblasts, by introducing a methodology which utilizes three printheads of the bioprinter to model aged myocardium. Then, using cell-specific proteins, the cell types that comprised each region are confirmed using immunofluorescence. Next, the beating characteristics are analyzed. Finally, the engineered aged post-MI tissue model is used as a benchtop platform to assess the therapeutic effects of stem cell-derived extracellular vesicles on the scar region. As a result, high viability (>74%) was observed\u00a0in each region of the printed model. Constructs demonstrated functional behavior, exhibiting a beating velocity of 6.7\u2009\u03bcm/s and a frequency of 0.3\u2009Hz. Finally, the effectiveness of hiPSC-EV and MSC-EV treatment was assessed. While hiPSC-EV treatment showed no significant changes, MSC-EV treatment notably increased cardiomyocyte beating velocity, frequency, and confluency, suggesting a regenerative potential. In conclusion, we envision that our approach of modeling post-MI aged myocardium utilizing three printheads of the bioprinter may be utilized for various applications in aged cardiac microenvironment modeling and testing novel therapeutics.\n\nID: 38570846\nTitle: Hyaluronic acid stimulation of stem cells for cardiac repair: a cell-free strategy for myocardial infarct.\nAbstract: Myocardial infarction (MI), a representative form of ischemic heart disease, remains a huge burden worldwide. This study aimed to explore whether extracellular vesicles (EVs) secreted from hyaluronic acid (HA)-primed induced mesenchymal stem cells (HA-iMSC-EVs) could enhance the cardiac repair after MI. HA-iMSC-EVs showed typical characteristics for EVs such as morphology, size, and marker proteins expression. Compared with iMSC-EVs, HA-iMSC-EVs showed enhanced tube formation and survival against oxidative stress in endothelial cells, while reduced reactive oxygen species (ROS) generation in cardiomyocytes. In THP-1 macrophages, both types of EVs markedly reduced the expression of pro-inflammatory signaling players, whereas HA-iMSC-EVs were more potent in augmenting anti-inflammatory markers. A significant decrease of inflammasome proteins was observed in HA-iMSC-EV-treated THP-1. Further, phospho-SMAD2 as well as fibrosis markers in TGF-\u03b21-stimulated cardiomyocytes were reduced in HA-iMSC-EVs treatment. Proteomic data showed that HA-iMSC-EVs were enriched with multiple pathways including immunity, extracellular matrix organization, angiogenesis, and cell cycle. The localization of HA-iMSC-EVs in myocardium was confirmed after delivery by either intravenous or intramyocardial route, with the latter increased intensity. Echocardiography revealed that intramyocardial HA-iMSC-EVs injections improved cardiac function and reduced adverse cardiac remodeling and necrotic size in MI heart. Histologically, MI hearts receiving HA-iMSC-EVs had increased capillary density and viable myocardium, while showed reduced fibrosis. Our results suggest that HA-iMSC-EVs improve cardiac function by augmenting vessel growth, while reducing ROS generation, inflammation, and fibrosis in MI heart.\n\nID: 37811703\nTitle: Combinatorial Effect of Biomaterials and Extracellular Vesicle Therapy for Heart Failure with Reduced Ejection Fraction: A Systematic Review of Preclinical Studies.\nAbstract: Heart failure, a pervasive global health burden, necessitates innovative therapeutic strategies. Extracellular vesicles (EVs) have emerged as promising contenders for cardiac repair, owing to their profound influence on fibrosis and inflammation. Merging EVs with biomaterials holds the potential for a synergistic leap in therapeutic efficacy. In this review, the impact of combining EVs with biomaterials in preclinical heart failure models is scrutinized. Fifteen studies, predominantly employing mesenchymal stromal cell-derived EVs along with hyaluronic acid or peptides in coronary ligation models, meet these stringent criteria. The amalgamation of EVs and biomaterials consistently enhances cardiac ejection fraction (1.39; 95% CI: 0.68, 2.11; p\u00a0=\u00a00.0001) and fractional shortening (1.46, 95% CI: 0.70, 2.22; p\u00a0=\u00a00.0002) compared to EV monotherapy. Secondary outcomes similarly showcased improvement in the combined treatment group. Although the number of studies analyzed is modest, no indications of publication bias surface. In summary, combination therapy with EVs and biomaterials enhances therapeutic benefit in preclinical heart failure models. The consistent improvement observed across diverse EV sources, biomaterials, and animal models underscores the exciting potential of this synergistic approach.\n\nID: 37742067\nTitle: Photoacoustic Imaging Endometriosis Lesions with Nanoparticulate Polydopamine as a Contrast Agent.\nAbstract: Endometriosis (EM) is a prevalent and debilitating gynecological disorder primarily affecting women of reproductive age. The diagnosis of EM is historically hampered by delays, owing to the absence of reliable diagnostic and monitoring techniques. Herein, it is reported that photoacoustic imaging can be a noninvasive modality for deep-seated EM by employing a hyaluronic-acid-modified polydopamine (PDA@HA) nanoparticle as the contrast agent. The PDA@HA nanoparticles exhibit inherent absorption and photothermal effects when exposed to near-infrared light, proficiently converting thermal energy into sound waves. Leveraging the targeting properties of HA, distinct photoacoustic signals emanating from the periphery of orthotopic EM lesions are observed. These findings are corroborated through anatomical observations and in vivo experiments involving mice with green fluorescent protein-labeled EM lesions. Moreover, the changes in photoacoustic intensity over a 24 h period reflect the dynamic evolution of PDA@HA nanoparticle biodistribution. Through the utilization of a photoacoustic ultrasound modality, in vivo assessments of EM lesion volumes are conducted. This innovative approach not only facilitates real-time monitoring of the therapeutic kinetics of candidate drugs but also obviates the need for the sacrifice of experimental mice. As such, this study presents a promising avenue for enhancing the diagnosis and drug-screening processes of EM.\n\nID: 37669775\nTitle: Formation and Investigation of Cell-Derived Nanovesicles as Potential Therapeutics against Chronic Liver Disease.\nAbstract: A new therapeutic approach using cell-derived nanovesicles (cdNVs) is offered here to overcome the lack of effective treatments for liver fibrosis, a reversible chronic liver disease. To achieve this goal the formation and purification of cdNVs from untreated, quiescent-like, or activated LX-2 cells, an immortalized human hepatic stellate cell (HSC) line with key features of transdifferentiated HSCs are established. Analysis of the genotype and phenotype of na\u00efve and transdifferentiated LX-2 cells activated through transforming growth factor beta 1, following treatment with cdNVs, reveals a concentration-dependent fibrosis regression. The beneficial fibrosis-resolving effects of cdNVs are linked to their biomolecular corona. Liposomes generated using lipids extracted from cdNVs exhibit a reduced antifibrotic response in perpetuated LX-2 cells and show a reduced cellular uptake. However, incubation with soluble factors collected during purification results in a new corona, thereby restoring fibrosis regression activity. Overall, cdNVs display encouraging therapeutic properties, making them a promising candidate for the development of liver fibrosis resolving therapeutics.\n\nID: 37385632\nTitle: Extracellular Vesicles Derived from Mesenchymal Stem Cells as Cell-Free Therapy for Intrauterine Adhesion.\nAbstract: Intrauterine adhesion (IUA) can occur after trauma to the basal layer of the endometrium, contributing to severe complications in females, such as infertility and amenorrhea. To date, the proposed therapeutic strategies are targeted to relieve IUA, such as hysteroscopic adhesiolysis, Foley catheter balloon, and hyaluronic acid injection have been applied in the clinic. However, these approaches showed limited effects in alleviating endometrial fibrosis and thin endometrium. Mesenchymal stem cells (MSCs) can offer the potential for endometrium regeneration owing to reduce inflammation and release growth factors. On this basis, MSCs have been proposed as promising methods to treat intrauterine adhesion. However, due to the drawbacks of cell therapy, the possible therapeutic use of extracellular vesicles released by stem cells is raising increasing interest. The paracrine effect, mediated by MSCs derived extracellular vehicles (MSC-EVs), has recently been suggested as a mechanism for their therapeutic properties. Here, we summarizes the main pathological mechanisms involved in intrauterine adhesion, the biogenesis and characteristics of extracellular vesicles, explaining how these vesicles could provide new opportunities for MSCs.\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.

Sorafenib, a multikinase inhibitor of RAF/VEGFR/PDGFR, can suppress these pathways, but its clinical utility is limited by hydrophobicity, toxicity, and poor tumor penetration. We engineered hyaluronic acid-coated niosomes encapsulating sorafenib (SOR@Nio/HA) to enable CD44-targeted delivery to OSCC cells. SOR@Nio/HA displayed a mean hydrodynamic diameter of 177\u00b18 nm (PDI=0.23-0.26) and high encapsulation efficiency (86.34%), with pH-responsive release (45% at pH=5.5 and 30% at pH=7.4, in 24 hr). In CAL27 cells, SOR@Nio/HA significantly enhanced cytotoxicity versus free sorafenib, lowering IC50 from 11.8\u00b11.1 \u00b5M to 5.2\u00b10.9 \u00b5M (P<0.01), and increased Annexin V/PI-defined apoptosis relative to controls. qRT-PCR showed suppression of NF-\u03baB targets, with COX-2 and MMP-9 reduced to 0.35-fold and 0.32-fold of the control, respectively, alongside a pro-apoptotic shift in the BAX/BCL-2 axis. Collectively, these data indicate that SOR@Nio/HA improves intracellular delivery and potentiates sorafenib's antitumor activity by CD44-mediated uptake and inhibition of NF-\u03baB-driven inflammatory and invasive programs. HA-guided niosomal sorafenib warrants in vivo validation as a selective nanotherapeutic strategy for OSCC.\n --- END ACTUAL ABSTRACT FOR 42610136 ---\n\n- ERROR: You cited ID: 42602668 for the quote: \"Hyaluronic acid (HA)-functionalized platform featuring dual enzyme/ROS-triggered release and CD44-mediated active targeting (HA@Cel/NPs).\"\n FACT: Strict Misquote Detected!

Celastrol (Cel)'s oral translation is limited by poor bioavailability and lack of lesion-specific targeting. To overcome these barriers, we constructed a hyaluronic acid (HA)-functionalized platform featuring dual enzyme/ROS-triggered release and CD44-mediated active targeting (HA@Cel/NPs) for treating ulcerative colitis (UC), colitis-associated colorectal cancer (CAC), and colon cancer. HA@Cel/NPs were fabricated using \u03b2-cyclodextrin and 4-(hydroxymethyl) phenylboronic acid as dual-responsive linkers. Physicochemical properties, drug release profiles, cellular uptake, anti-inflammatory activity, macrophage polarization, and anticancer activity were systematically evaluated in vitro. In vivo biodistribution and therapeutic efficacy were assessed in UC, CAC, and colon cancer mouse models, with anti-PD-L1 combination therapy in the colon cancer setting. HA@Cel/NPs exhibited uniform size (76.87 \u00b1 2.65 nm, PDI 0.166 \u00b1 0.012), stayed stable for 14 days, and achieved ~71% Cel release under high H2O2/\u03b1-amylase conditions within 8 h. The nanocarriers enhanced cellular uptake and promoted M1-to-M2 macrophage polarization in inflamed macrophages, while inducing potent CT26 cell apoptosis. Orally administered HA@Cel/NPs alleviated UC severity and suppressed CAC progression, with significantly reduced tumor burden. In colon cancer, intravenous HA@Cel/NPs combined with intraperitoneal anti-PD-L1 significantly boosted CD8\u207a and CD4\u207a T cell infiltration and effectively eradicated established tumors compared with HA@Cel/NPs monotherapy. HA@Cel/NPs offer a versatile, dual-route platform that bridges inflammation management and cancer immunotherapy, distinguishing itself from single-mechanism or single-disease nanocarriers.\n --- END ACTUAL ABSTRACT FOR 42602668 ---\n\n- ERROR: You cited ID: 42586120 for the quote: \"HA-based nanocarriers for cancer therapy: molecular design, biointerface mechanisms, and translational challenges.\"\n FACT: Strict Misquote Detected!

This review examines studies published from 2019 to 2026, with emphasis on high-quality research in leading journals, and connects the structural parameters of HA with quantitative drug delivery efficiency and therapeutic performance. The major HA-based carrier systems, including micelles, liposomes, polymeric nanoparticles, metal-organic frameworks, and electrospun fiber systems, are critically analyzed in relation to HA molecular weight, degree of substitution, and ligand density, as well as their effects on hydrodynamic size, zeta potential, colloidal stability, and cellular uptake. Across these studies, the most effective designs generally feature nanoscale dimensions that balance circulation and tumor penetration while maintaining near-neutral or slightly negative surface potentials to minimize nonspecific interactions, highlighting the importance of rational physicochemical design for improving therapeutic performance.\rQuantitative models of drug release, together with in vitro potency indices such as half-maximal inhibitory concentration (IC50) and combination index, as well as in vivo pharmacokinetic and efficacy indicators including half-life, area under the curve (AUC), and tumor-to-organ ratio, demonstrate how the configuration of HA influences therapeutic selectivity and systemic safety. To improve the rigor and reproducibility of future studies, this review further proposes a concise reporting framework integrating materials characterization, biological evaluation, and animal experiments, while highlighting the current limitations in standardization and cross-study comparability.\rIn conclusion, this review summarizes the current design principles of HA-based nanocarriers while critically discussing the remaining challenges, including CD44 heterogeneity, microenvironmental competition, and the lack of standardized evaluation strategies. Together, these perspectives provide practical guidance for the rational design, comparative evaluation, and clinical translation of next-generation HA-based nanocarriers.\r.\n --- END ACTUAL ABSTRACT FOR 42586120 ---\n\n- ERROR: You cited ID: 42493250 for the quote: \"supports HA-CD44-mediated internalization.\"\n FACT: Strict Misquote Detected!

Here, we developed a hyaluronic acid (HA)-coated MEL-based polymersome (PMHA) for CD44-targeted codelivery of MEL and celecoxib (CXB). MEL was incorporated into the vesicular membrane, whereas CXB was loaded into the hydrophobic domain. PMHA showed a hydrodynamic diameter of 265.5\u2009\u00b1\u20091.6\u2009nm, a zeta-potential of -21.14\u2009\u00b1\u20091.1\u2009mV, a CXB encapsulation efficiency of 70.81\u2009\u00b1\u20094.18%, and a drug loading capacity of 12.87\u2009\u00b1\u20091.92%. In lipopolysaccharide (LPS)-stimulated RAW 264.7 macrophages, anti-CD44 antibody blocking reduced Alexa Fluor 647-labeled PMHA uptake by approximately 37.5%, supporting HA-CD44-mediated internalization. PMHA reduced MEL-associated cytotoxicity and hemolytic activity and enabled pH-responsive CXB release. Codelivery of MEL and CXB suppressed cyclooxygenase-2\u2009(COX-2) and tumor necrosis factor-\u03b1 (TNF-\u03b1) expression, with combination index (CI) values of 0.48 and 0.67, respectively. These findings support further evaluation of PMHA as a macrophage-targeted anti-inflammatory nanoplatform.\n --- END ACTUAL ABSTRACT FOR 42493250 ---\n\n- ERROR: You cited ID: 42435660 for the quote: \"Central conclusion is that molecular glycoengineering is most defensible when carbohydrate chemistry is linked to measurable receptor engagement.\"\n FACT: Strict Misquote Detected!

The field is scientifically attractive because cancer cells and tumor-associated stromal cells remodel their glycocalyx, overexpress selected carbohydrate-recognizing receptors and display altered metabolic demand; however, the translation of glycoengineered nanomedicine remains limited by low tumor delivery efficiency, heterogeneous receptor density, competitive off-target uptake by liver and macrophages, batch-to-batch variation in ligand density and insufficient quantitative reporting. This review re-frames carbohydrate-mediated cancer drug delivery as an evidence-weighted design problem. It integrates receptor-density data, particle-size boundaries, ligand-density ranges, release-rate targets, in vitro uptake metrics, pharmacokinetic endpoints and preclinical efficacy readouts into a quantitative framework. Special attention is given to hyaluronic acid-CD44, galactose/GalNAc-ASGPR, mannose-CD206, sialylated glycan-siglec/selectin, beta-galactoside-galectin and glucose/GLUT-related approaches, with emphasis on what the available data can and cannot prove. The central conclusion is that molecular glycoengineering is most defensible when carbohydrate chemistry is linked to measurable receptor engagement, competitive inhibition, uptake kinetics, intracellular drug exposure and statistically stronger antitumor benefit rather than to generic claims of active targeting. The framework explicitly links anomeric configuration, glycosidic linkage, branching, sulfation/acetylation, epitope display and glycan-protein hydration to receptor-specific pharmacological outcomes, thereby shifting the emphasis from general nanomedicine performance to carbohydrate structure-activity relationships required for a carbohydrate-chemistry readership.\n --- END ACTUAL ABSTRACT FOR 42435660 ---\n\n- ERROR: You cited ID: 42421100 for the quote: \"Deep infiltrating endometriosis and adenomyosis are characterized by fibrosis, extracellular matrix remodeling, tissue stiffening.\"\n FACT: Strict Misquote Detected!

Although they share several molecular features, the mechanisms by which endometrium-derived tissues develop distinct pathological phenotypes in different tissue environments remain incompletely understood. This review summarizes shared and divergent pathogenic mechanisms, focusing on lesion-specific microenvironments. This narrative review was based on a PubMed literature search from the year of the first publication through December 2025 using terms related to endometriosis, adenomyosis, mitochondrial function, oxidative stress, fibrosis, mechanical stress, and calcium signaling. Both disorders develop in the context of repetitive tissue injury, estrogen-dependent repair responses, chronic inflammation, oxidative stress, and mitochondrial dysfunction. However, differences in lesion location and microenvironment appear to drive distinct pathological phenotypes. In superficial peritoneal endometriosis and ovarian endometrioma, mitochondrial adaptation primarily supports hypoxia tolerance, oxidative stress responses, angiogenesis, cellular survival, and metabolic reprogramming. In contrast, deep infiltrating endometriosis and adenomyosis are characterized by fibrosis, extracellular matrix remodeling, tissue stiffening, and adaptation to mechanical stress. In adenomyosis, mitochondrial regulation of calcium homeostasis, smooth muscle contractility, reactive oxygen species production, and TGF-\u03b2-related fibrotic signaling may play important roles in disease progression. We propose a proliferation-fibrosis divergence model in which common pathogenic stimuli are integrated through mitochondria-dependent responses to distinct local microenvironments. Mitochondria may act as central regulators linking hypoxic adaptation, inflammation, metabolism, fibrosis, and mechanotransduction, thereby influencing whether disease progression favors proliferative expansion or fibrotic remodeling. This framework may provide a basis for future mechanism-based precision therapeutic strategies.\n --- END ACTUAL ABSTRACT FOR 42421100 ---\n\n- ERROR: You cited ID: 42418937 for the quote: \"TSS administration reduced endometriosis-like lesion size and was associated with suppression of Th17-related inflammatory mediators.\"\n FACT: Strict Misquote Detected!

This study examined the effects of TSS on fecundity and endometriosis-like lesions during pregnancy in a murine model of endometriosis. Endometriosis model mice were divided into four groups: Sham operation\u202f+\u202fcontrol diet (Sham/Cont), Sham operation\u202f+\u202f3% TSS diet (Sham/TSS), Endometrium dispersion\u202f+\u202fcontrol diet (End/Cont), and Endometrium dispersion\u202f+\u202f3% TSS diet (End/TSS). Mating was initiated one day after surgery, and females were sacrificed on postpartum day 3. Endometriosis-like lesion size, inflammatory cytokine levels, and reproductive outcomes were evaluated. Time to delivery tended to be shorter in the End/TSS group than in the End/Cont group (median: 23.5 vs. 27 days), although the difference was not statistically significant. The maximum lesion diameter in the End/TSS group was significantly smaller compared to the End/Cont group (median: 4.54\u202fmm vs. 7.76\u202fmm, p\u202f=\u202f0.044). Concentrations of the inflammatory cytokines MIP-3\u03b1 and IL-17A were significantly lower in the End/TSS group (MIP-3\u03b1: 14.54 [12.91, 18.98] vs. 25.26 [16.81, 48.58] pg/mg protein, p\u202f=\u202f0.019, IL-17A: 10.00 [9.05, 18.76] vs. 19.06 [16.75, 82.81] pg/mg protein, p\u202f=\u202f0.019). TSS administration reduced endometriosis-like lesion size and was associated with suppression of Th17-related inflammatory mediators in a murine model of endometriosis. Consequently, the administration of TSS tended to shorten the time to pregnancy. These findings suggest that TSS may exert immunomodulatory effects within endometriosis lesions and could represent a potential non-hormonal therapeutic approach during the peri-conceptional period.\n --- END ACTUAL ABSTRACT FOR 42418937 ---\n\n- ERROR: You cited ID: 42401307 for the quote: \"Steroidal alkaloids as a mechanistically rational, non-hormonal approach to target lesion persistence and fibrosis.\"\n FACT: Strict Misquote Detected!

The central question this review seeks to answer is: are steroidal alkaloids - nitrogenous plant-derived steroids with a unique structure - a mechanistically sensible, non-hormonal alternative that can simultaneously target the inflammatory, fibrotic and epigenetic drivers of endometriotic lesion persistence, while preserving fertility and avoiding systemic hormonal suppression? A growing body of evidence points to non-hormonal molecular networks including immune dysregulation, angiogenesis, and resistance to apoptosis as drivers of lesion persistence. These molecular disturbances are associated with treatment resistance and limit the long-term efficacy of hormone-based therapies. This review synthesises recent mechanistic advances that describe the non-hormonal signalling pathways that maintain endometriotic lesions, with a specific emphasis on NF-\u03baB-mediated sterile inflammation, inflammasome activation, PI3K/Akt/mTOR-dependent survival signalling, Hedgehog-driven fibrosis and epigenetic repression of progesterone receptor expression. Steroidal alkaloids are critically reviewed as multitarget modulators suppressing inflammatory signalling, inhibiting invasive and fibrotic remodelling, and restoring apoptotic sensitivity in this pathophysiological context, without direct systemic oestrogen deprivation. Structural determinants of steroidal alkaloid activity, including glycosylation status, nitrogen topology and configuration of the steroidal scaffold, are discussed in the context of pathway selectivity, pharmacokinetics and toxicity. Preclinical in vitro and in vivo evidence is critically reviewed in the context of key translational limitations such as bioavailability constraints, narrow therapeutic index and teratogenic risk from developmental pathway inhibition. This review highlights steroidal alkaloids as a mechanistically rational, non-hormonal approach to target lesion persistence and fibrosis in endometriosis, integrating molecular, pharmacological and structural insights, and outlines the major hurdles that must be overcome for clinical translation. The main objective of this review is to address a specific unanswered question: can steroidal alkaloids with their multitarget pharmacology offer a biologically coherent, non-hormonal strategy for the treatment of endometriosis that goes beyond oestrogen deprivation to target the molecular machinery of lesion survival, fibrosis and immune dysregulation. This question is addressed by reviewing the nonhormonal signalling networks that support ectopic lesions, the structural and pharmacokinetic properties of steroidal alkaloids that are relevant to these pathways, and the translational challenges that need to be addressed for clinical translation.\n --- END ACTUAL ABSTRACT FOR 42401307 ---\n\n- ERROR: You cited ID: 42401301 for the quote: \"combining CD44-targeted delivery with GSH-responsive prodrug activation.\"\n FACT: Strict Misquote Detected!

In this study, we designed a hyaluronic acid-based prodrug system, HA-Ns-Dox, that integrates receptor-mediated cellular uptake with intracellular glutathione (GSH)-responsive activation. A doxorubicin (Dox) prodrug modified with a 2-nitrobenzenesulfonyl (Ns) group was synthesized and subsequently conjugated to hyaluronic acid (HA) via click chemistry to generate HA-Ns-Dox with both CD44-targeting capability and GSH-responsive activation properties. HA-Ns-Dox formed stable nanosized assemblies in aqueous solution and exhibited high stability under low-GSH conditions mimicking extracellular environments, whereas concentration-dependent activation of Dox was observed under high-GSH conditions mimicking intracellular reductive environments. In vitro studies demonstrated that HA-Ns-Dox was selectively internalized into the CD44-high human breast cancer cell line MDA-MB-231, accompanied by intracellular prodrug activation and nuclear accumulation of Dox. In contrast, cellular uptake and activation were minimal in the CD44-low cell line MCF-7, and cytotoxicity was significantly suppressed even at high concentrations. Cytotoxicity studies further revealed that HA-Ns-Dox exhibited significant antiproliferative activity in CD44-high cells while substantially reducing toxicity toward non-target cells. Collectively, these findings demonstrate the potential of combining CD44-targeted delivery with GSH-responsive prodrug activation to improve cancer cell selectivity.\n --- END ACTUAL ABSTRACT FOR 42401301 ---\n\n- ERROR: You cited ID: 42346610 for the quote: \"High levels of reactive oxygen species (ROS) reinforce lesion survival and chronic inflammation.\"\n FACT: Strict Misquote Detected!

High recurrence rates and enduring symptoms despite current treatments underscore the need for a more thorough understanding of its intricate biology. There is growing evidence that the interaction among oxidative stress (OS), microbiome dysbiosis, and epigenetic dysregulation contributes to immunological activation, hormonal imbalance, and the persistence of ectopic lesions. Important disease mechanisms, such as progesterone resistance, inflammatory signaling, and aberrant cellular proliferation, are influenced by epigenetic changes, which include aberrant DNA methylation, histone modifications, and dysregulated non-coding RNAs. Simultaneously, high levels of reactive oxygen species (ROS) reinforce lesion survival and chronic inflammation by promoting angiogenesis, fibrosis, and tissue damage. Changes in the microbiome also affect immunological responses, oxidative balance, estrogen metabolism, and epigenetic control, indicating the existence of interrelated pathogenic loops. This narrative review presents an integrated mechanistic framework for endometriosis, summarizing the available data that connect these pathways. Furthermore, the growing implications of non-invasive biomarkers and precision medicine techniques highlight the potential for improved diagnosis, disease classification, and targeted treatment approaches.\n --- END ACTUAL ABSTRACT FOR 42346610 ---\n\n- ERROR: You cited ID: 42235198 for the quote: \"HA and GA-NPs... achieving synergistic therapeutic effects against psoriasis.\"\n FACT: Ellipses (...) are strictly forbidden.

In this study, hyaluronic acid (HA) and glycyrrhetinic acid (GA) were separately conjugated to D-alpha tocopherol acid polyethylene glycol succinate (TPGS), which subsequently self-assembled into nanoparticles (HA/GA-NPs). Bletilla striata polysaccharide (BSP) and HA were employed as the microneedle matrix to fabricate soluble microneedles incorporating the nanoparticles (HA/GA-NPs-MNs). This strategy combined the CD44-targeting capability and anti-inflammatory activity of the nanoparticles with the immunomodulatory function and efficient penetration-enhancing ability of the BSP-based microneedles, thereby achieving synergistic therapeutic effects against psoriasis. In vitro studies demonstrated that the CD44-targeting capability of HA/GA-NPs enhanced cellular uptake, reduced intracellular ROS expression, and suppressed the inflammatory proliferation of HaCaT cells. Concurrently, BSP and HA/GA-NPs synergistically promote M2 polarization in RAW264.7 cells while suppressing the production of NO and proinflammatory factors IL-6, TNF-\u03b1, and IL-1\u03b2. Furthermore, HA/GA-NPs-MNs enhanced drug accumulation and skin penetration, enabling efficient delivery into the deeper skin layers. During in vivo studies, the system was observed to significantly enhance immune regulation and demonstrated the strongest efficacy in suppressing psoriatic inflammatory infiltration. The primary therapeutic mechanism of HA/GA-NPs-MNs against psoriasis involved the blockade of STAT3 phosphorylation to inhibit IL-23 signaling and downstream IL-17 release. The biosafety assessment confirmed high dermal and hemocompatibility of the system. This work presented a novel integrated platform of multifunctional self-assembled nanoparticles and immunomodulatory microneedles for the topical treatment of psoriasis.\n --- END ACTUAL ABSTRACT FOR 42235198 ---\n\n- ERROR: You cited ID: 42211882 for the quote: \"engineered ginseng stems and leaves-derived EVs... through CD44 receptor-mediated accumulation.\"\n FACT: Ellipses (...) are strictly forbidden.

Current treatments often face challenges including limited targeting efficacy and systemic side effects. To develop a novel targeted therapy for RA, this study constructed a functionalized extracellular vesicle (EV) system by engineering ginseng stems and leaves-derived EVs with hyaluronic acid (HA) modification and curcumin (Cur) loading (Cur@EVs-PH). Structurally, the EVs-PH drug-loaded nanoplatform integrates the remarkable anti-inflammatory and antioxidant properties of EVs with the prolonged circulation capacity conferred by PEG. This design further capitalizes on the targeting ability of HA, thereby providing a robust structural foundation for the efficient delivery of therapeutics to disease sites. Our results demonstrated that the designed system achieved enhanced inflammatory targeting through CD44 receptor-mediated accumulation and exhibited potent anti-inflammatory and antioxidant activities. In the collagen-induced arthritis model, Cur@EVs-PH significantly alleviated joint swelling, reduced pathological scores and normalized immune organ indices. Mechanistic studies revealed that the therapeutic effects were mediated through suppression of pro-inflammatory cytokines and promotion of macrophage M2 polarization. This integrated strategy combining natural EVs, targeted modification and active drug loading provides a promising platform for the treatment of RA and other inflammatory diseases.\n --- END ACTUAL ABSTRACT FOR 42211882 ---\n\n- ERROR: You cited ID: 42202863 for the quote: \"HA, a natural component of the human extracellular matrix, serves as an ideal material for integrating osteosarcoma therapy and postoperative bone regeneration.\"\n FACT: Strict Misquote Detected!

Clinical treatments face major challenges, including postoperative recurrence, refractory bone defects, and inadequate targeting of chemotherapeutic drugs. Hyaluronic acid (HA), a natural component of the human extracellular matrix, serves as an ideal material for integrating osteosarcoma therapy and postoperative bone regeneration, attributed to its unique properties including CD44-mediated tumor targeting, tumor microenvironment-responsive degradation, excellent biocompatibility, and functional tunability. This review summarizes recent advances in HA-based materials for osteosarcoma therapy. HA acts as a versatile carrier for chemotherapeutic drugs (e.g. doxorubicin (DOX), cisplatin (CDDP)) and therapeutic nucleic acids, via nanoparticles, liposomes, or hydrogels. These carriers enhance intratumoral drug accumulation, reduce systemic toxicity, evade immune recognition, and facilitate intracellular drug delivery. Incorporating bioactive glass or magnesium-based nanomaterials into HA constructs a multifunctional therapy-regeneration system, which simultaneously inhibits tumor growth and promotes bone regeneration, addressing postoperative bone defects. Furthermore, we analyze key obstacles to clinical translation, such as rapid degradation, insufficient hydrogel mechanical strength, and poor sterilization compatibility, and propose solutions including chemical cross-linking and composite modification. These insights provide valuable guidance for the precise design of HA-based biomaterials and their clinical translation, aligning with the demand for therapy-repair integration in regenerative medicine.\n --- END ACTUAL ABSTRACT FOR 42202863 ---\n\n- ERROR: You cited ID: 42093737 for the quote: \"exploiting HA's selective affinity for CD44 (highly expressed by both GBM and GSCs).\"\n FACT: Strict Misquote Detected!

The cavity left after tumor resection represents a valuable opportunity to deliver therapeutics locally via the placement of conformable scaffolds for the immediate chemotherapeutic targeting of GSCs and residual glioblastoma cells. We hypothesized that Surgiflo\u2122, a moldable, FDA-approved gelatin-based hemostatic paste, could serve as a dual-purpose platform that minimizes postoperative bleeding and functions as a conformable, local, and sustained drug-delivery system. We incorporated a pH-sensitive designed hyaluronic acid-doxorubicin polymer-drug conjugate (HA-DOX) into the Surgiflo\u2122 matrix, exploiting HA's selective affinity for CD44 (highly expressed by both GBM and GSCs) and promoting the depletion of GBM and GSCs via immunogenic cell death (ICD)-inducing properties of DOX. In vitro studies of HA-DOX-containing paste confirmed enhanced HA-DOX uptake in GSC-enriched models, improved ICD induction in GBM cells, favorable biocompatibility, and sustained drug release. In vivo evaluations revealed that intracavitary implantation of the HA-DOX-containing paste significantly prolonged the median survival of treated mice compared to the untreated group (37 days vs 25 days, respectively) and modulated the glioblastoma-associated TIME, resulting in a 44% reduction in GSC levels and a significant increase in CD8+ T cell levels (\u2217p < 0.5), compared to resected mice. Embedding HA-DOX within Surgiflo\u2122 offers a promising strategy for localized, sustained delivery of chemotherapeutics to the resected cavity, with the potential to improve therapeutic outcomes and minimize systemic toxicity in postoperative glioblastoma treatment.\n --- END ACTUAL ABSTRACT FOR 42093737 ---\n\n- ERROR: You cited ID: 42055152 for the quote: \"modified with hyaluronic acid targeting CD44, which is highly expressed on pancreatic cells.\"\n FACT: Strict Misquote Detected!

Although gemcitabine (GEM) is the gold standard for PC, the acquired resistance and severe myelosuppression limit clinical utility. It has been found that abnormal aerobic glycolysis may be responsible for drug resistance in PC. Disulfiram (DSF), a commonly used anti-alcoholic drug, possesses potent anti-tumor activity combined with copper. Nevertheless, poor water solubility and neurotoxicity restrict clinical applications. Therefore, our group modified the structure of DSF and synthesized a novel compound CPD12C15, which exhibited stronger anti-tumor activity and lower neurotoxicity than DSF. Nanoparticles with excellent release properties, modified with hyaluronic acid (HA) targeting CD44, which is highly expressed on pancreatic cells, can evade the removal of natural defense system and enhance tumor-targeting ability. Herein, CPD12C15 was loaded into HA-modified PLGA nanoparticles (HPC-NP) in order to improve the sustained release properties and active targeting ability. Our research revealed that CPD12C15 combined with Cu (HPC-NP/Cu) could inhibit tumor proliferation, migration, invasion and induce apoptosis by suppressing the aerobic glycolysis pathway, which further inhibited cell stemness and drug resistance in vivo and in vitro, suggesting that it may be a potential strategy for PC treatment.\n --- END ACTUAL ABSTRACT FOR 42055152 ---\n\n- ERROR: You cited ID: 42002329 for the quote: \"Lower-MW HA generally promotes barrier penetration, cellular uptake, and pro-inflammatory responses.\"\n FACT: Strict Misquote Detected!

Among the key design parameters of HA-based nanocarriers, molecular weight (MW) critically influences biological performance; yet the optimal MW remains controversial. Although higher MW is often assumed to enhance CD44 binding and targeting efficiency, evidence indicates that its effects are multidimensional, context-dependent, and frequently non-linear. This review systematically examines how the MW of HA regulates cellular uptake, active targeting, drug solubilization, release kinetics, biodegradation, immunomodulation, and translational potential. At the cellular level, HA MW modulates multivalent CD44 engagement and receptor clustering, often producing a bell-shaped relationship with internalization efficiency. At the tissue level, MW affects tumor accumulation through competing influences on receptor avidity, nanoparticle size, and systemic clearance. Lower-MW HA generally promotes barrier penetration, cellular uptake, and pro-inflammatory responses, whereas higher-MW HA enhances stability, anti-inflammatory signaling, and circulation time but may reduce uptake due to steric hindrance. Overall, optimal MW selection depends on nanocarrier design, disease context, and dominant biological barriers.

For patients with advanced, unresectable disease, transarterial chemoembolization (TACE) is a recommended first-line locoregional therapy. However, its efficacy is constrained by the inherent limitations of conventional embolic materials-such as non-target embolization, vessel recanalization, and incomplete distal occlusion-and by the low intra-tumoral delivery efficiency of chemotherapeutic agents. Furthermore, the high prevalence of p53 mutations (~\u200930%) in HCC drives tumorigenesis and chemoresistance, creating a critical therapeutic gap, especially within the hypoxic tumor microenvironment. To address these multifaceted challenges, we developed an innovative theranostic platform, CHSA/NAT. This system combines a radiopaque, thermosensitive hydrogel (NAT) for precise, image-guided vascular occlusion with CD44-targeted, glutathione (GSH)-responsive chitosan/hyaluronic acid nanomicelles (CHSA), which enable the smart delivery of arsenic trioxide (ATO)-a potent agent with p53-mutant corrective activity. In vitro, ATO demonstrated superior cytotoxicity over doxorubicin against multiple HCC cells under hypoxia. In a p53-mutant PLC/PRF/5 subcutaneous model, CHSA-ATO achieved a tumor inhibition rate of 84.6%, significantly outperforming free ATO and doxorubicin, and effectively modulated apoptotic proteins (downregulating mutant p53/Bcl-2, upregulating Bax). Crucially, superselective administration of CHSA/NAT enabled successful embolization with clear radiological visualization in rat hepatic and renal arteries, demonstrating its precise image\u2011guided delivery and embolization capability. Most importantly, in an orthotopic rat HCC model, the combined treatment exhibited powerful synergistic efficacy, attaining a remarkable 96% tumor suppression rate and significantly prolonging survival, with a favorable safety profile. This work presents a novel \"embolization\u2011imaging\u2011targeted chemotherapy\" strategy that simultaneously overcomes the key limitations of conventional TACE and ATO delivery, offering a promising and translatable nanoplatform for the effective treatment of advanced HCC.\n --- END ACTUAL ABSTRACT FOR 41992318 ---\n\n- ERROR: You cited ID: 41968335 for the quote: \"Immune-Hemostatic Crosstalk... establish a pro-fibrotic niche via TGF-\u03b21 signalling.\"\n FACT: Ellipses (...) are strictly forbidden.

This review synthesises current molecular evidence to propose a unified mechanistic framework initiated by tissue injury and repair (TIAR), aberrant stem cell activation, or de novo metaplasia, all of which converge to disrupt the endometrial-myometrial interface disruption (EMID). Following this structural breach, a self-perpetuating 'vicious cycle' is triggered, driven by four interconnected axes: (1) Hormonal Dysregulation, characterised by local hyper-estrogenism, progesterone resistance, and a specific paracrine prolactin loop that drives reactive myometrial hypertrophy; (2) Immune-Hemostatic Crosstalk, where activated platelets and M2-polarised macrophages establish a pro-fibrotic niche via TGF-\u03b21 signalling; (3) Hypoxia and Neuroangiogenesis, where HIF-1\u03b1 stabilisation orchestrates metabolic reprogramming (Warburg effect) and the pathological sprouting of sensory nerves, underpinning chronic pain; and (4) Epigenetic Fibrosis, driven by the oestrogen-slug-VEGF axis and HDAC-mediated chromatin remodelling leading to epithelial-mesenchymal transition (EMT). Furthermore, we clarify the genetic distinction between adenomyosis and uterine leiomyomas, highlighting their divergent responses to androgen receptor signalling. By elucidating these molecular targets, we discuss emerging non-hormonal therapeutics-including anti-platelet agents and dopamine agonists-offering mechanism-based strategies for fertility preservation.\n --- END ACTUAL ABSTRACT FOR 41968335 ---\n\n- ERROR: You cited ID: 41963751 for the quote: \"Surface-engineered polymeric nanoparticles... specific target overexpressed receptors on cancer cells, including CD44.\"\n FACT: Ellipses (...) are strictly forbidden.

Paclitaxel (PTX), a first-line chemotherapeutic agent widely used in breast cancer, is widely used due to its potent mechanism of action against rapidly dividing cancer cells. However, its clinical application is significantly hindered by poor solubility, systemic toxicity, and associated adverse effects. Encapsulating PTX in polymeric nanoparticles presents a promising strategy to overcome these limitations by extending drug release, enhancing drug's bioavailability, and enabling active targeting. This review uniquely focuses on recent advances in surface-functionalized polymeric nanoparticles specifically engineered for targeted delivery of PTX in breast cancer therapy and consolidates their translational relevance and next-generation design considerations. Unlike general reviews on polymeric nanocarriers, this article specifically focuses on ligand-functionalized polymeric nanoparticles designed for active targeting of breast cancer cells, integrating biological rationale, receptor specificity, and translational relevance. Surface-engineered polymeric nanoparticles functionalized with ligands such as folic acid, hyaluronic acid, aptamers, and peptides can specifically target overexpressed receptors on cancer cells, including CD44, HER2, and folate receptors. These ligand-receptor interactions facilitate receptor-mediated endocytosis, enhancing intracellular drug delivery while minimizing systemic toxicity. The review highlights key design considerations, including ligand density, nanoparticle architecture, and multifunctionality of next-generation PTX nanocarriers. The development of PTX-loaded polymeric nanoparticles with surface modifications represents a significant advancement in precision drug delivery for breast cancer, addressing key treatment challenges and paving the way for clinical translation.\n --- END ACTUAL ABSTRACT FOR 41963751 ---\n\n- ERROR: You cited ID: 42169331 for the quote: \"OSA-HA-modified OMVs exhibiting higher cellular internalization (75.4% at 12 h) than similarly modified EVs.\"\n FACT: Strict Misquote Detected!

To address these challenges, we engineered a targeted co-delivery platform by systematically comparing two representative, probiotic-derived extracellular vesicle carriers: outer membrane vesicles (OMVs) from Escherichia coli Nissle 1917 and extracellular vesicles (EVs) from Lactobacillus plantarum. Encapsulation efficiency (EE) of Cur was 41.6% for OMVs and 35.9% for EVs, whereas EE of Ant was 25.4% and 24.6%, respectively. Both vesicle types were further synergistically functionalized with specifically acylated epigallocatechin palmitate (EGCp) and octenyl succinic anhydride-grafted hyaluronic acid (OSA-HA). The incorporation efficiency of EGCp was 27.2% for OMVs and 37.3% for EVs. The self-assembly process yielded composite nanovesicles with a reduced particle size (OMVs: from 165.6 nm to 143.2 nm; EVs: from 156.8 nm to 120.8 nm) and a more negatively charged surface (from -20.8 mV to -37.5 mV for OMVs; from -18.3 mV to -35.3 mV for EVs) compared to their native counterparts, indicating improved colloidal properties. In addition, both engineered nanovesicles effectively protected the encapsulated bioactives, significantly enhancing their stability against simulated gastrointestinal digestion and oxidative stress. For example, the retention of Cur under oxidative conditions increased from 24.2% in unmodified OMVs to 69.1% in the optimized formulation within 2 h. Cellular uptake assays confirmed the OSA-HA coating achieved targeted delivery to inflammatory macrophages, with OSA-HA-modified OMVs exhibiting higher cellular internalization (75.4% at 12 h) than similarly modified EVs (61.8% at 12 h). While both types of functionalized nanovesicles enhanced intracellular antioxidant activity to a similar extent, the OMV-based system demonstrated superior suppression of pro-inflammatory mediators (NO, TNF-\u03b1, and IL-6) in mitigating lipopolysaccharide (LPS)-induced cell damage. This comparative study establishes a biocompatible probiotic-based colloidal platform, demonstrating the potential of two selected engineered probiotic vesicles and functionalized polysaccharides for the encapsulation and targeted cellular delivery of sensitive bioactive compounds.\n --- END ACTUAL ABSTRACT FOR 42169331 ---\n\n- ERROR: You cited ID: 42057185 for the quote: \"PE- and BV421-conjugated antibodies targeting virion incorporated proteins (CD38, CD44).\"\n FACT: Strict Misquote Detected!

However, advances in optics and fluidics have enabled cytometers primarily designed for cells to detect viruses and extracellular vesicles (EVs) through light scatter alone. In 2024, the CytoFLEX nano was released, marketed for the detection of particles as small as 40 nm; however, its performance has yet to be compared to a conventional instrument for FV. FV was utilized to evaluate performance of the CytoFLEX nano and a conventional flow cytometer (CytoFLEX S). Instrument scatter sensitivity was assessed using NIST beads (40-400 nm), and virus stocks [human immunodeficiency virus (HIV), human coronaviruses (HCoV)-229E and HCoV-OC43]. For fluorescence analysis, HIV virions were stained with PE- and BV421-conjugated antibodies targeting virion incorporated proteins (CD38, CD44), individually and in combination. Finally, HIV stocks were labeled with antibodies against the envelope (Env) glycoprotein and tetraspanins (CD9, CD81) to assess EVs within virus preparations. Compared to the CytoFLEX S, the CytoFLEX nano exhibited substantially greater scatter sensitivity, reflected by up to 50-fold higher signal-to-noise ratio across NIST-traceable beads and virus samples. This enabled clearer resolution of smaller populations, including bead populations\u2009<\u200970 nm that were undetectable on the CytoFLEX S, as well as improved resolution across all viruses. While both instruments reliably detected stained proteins on HIV virions, the CytoFLEX nano revealed a distinct population of tetraspanin-positive EVs within HIV stocks that was undetected on the CytoFLEX S. Using GFP-tagged HIV, we identified Env+ particles lacking GFP, indicating the presence of Env on EVs. The CytoFLEX nano exhibited markedly improved scatter sensitivity compared to the CytoFLEX S, improving detection of viruses and enabling detection of EV populations that were undetectable on the conventional instrument. While both platforms performed similarly for surface protein labeling, additional consideration of spectral overlap was needed with the CytoFLEX nano in multicolor experiments. These findings highlight that the complementary strengths of each platform can be utilized to more comprehensively characterize virus and EV populations, providing new opportunities to investigate nanoparticle heterogeneity.\n --- END ACTUAL ABSTRACT FOR 42057185 ---\n\n- ERROR: You cited ID: 42051963 for the quote: \"Endometriotic MenSCs... characterized using flow cytometry (CD29, CD44, CD73, CD105 positive).\"\n FACT: Ellipses (...) are strictly forbidden.

Dysregulated apoptosis and abnormal cell migration are key pathological features. Given current treatment limitations, novel strategies like mesenchymal stem cells (MSC) derived conditioned media (CM) are explored due to their rich secretome. To investigate the effects of CM from healthy menstrual blood-derived MSCs (MenSCs-CM) and human adipose tissue-derived MSCs (ADSCs-CM) on apoptosis and migration in endometriotic MenSCs. This in vitro study involved the isolation of endometriotic MenSCs from infertile women (25-35 yr) via menstrual blood. Mononuclear cells were cultured to passage 3, and characterized using flow cytometry (CD29, CD44, CD73, CD105 positive; CD34, CD38, CD45 negative). CM was prepared separately from healthy donor MenSCs and ADSCs. Endometriotic MenSCs were treated with healthy MenSCs-CM and ADSCs-CM independently. Cell migration (scratch assay), apoptosis (Annexin V), and Bax mRNA levels and Bax/Bcl-2 ratio (real-time polymerase chain reaction) were evaluated. Both ADSCs-CM and MenSCs-CM significantly increased during early and late apoptosis in endometriotic MenSCs (p < 0.001). Scratch assays showed significantly decreased MenSCs migration at 24, 48, and 72 hr (p < 0.001, p = 0.003, p < 0.001, respectively). Gene expression revealed significant increases in Bax mRNA (p = 0.013) and the Bax/Bcl-2 ratio (p = 0.044). CM from ADSCs and MenSCs of healthy women enhances apoptosis and inhibits endometriotic MenSCs migration in vitro, suggesting potential therapeutic strategies for endometriosis.\n --- END ACTUAL ABSTRACT FOR 42051963 ---\n\n- ERROR: You cited ID: 42010698 for the quote: \"Glandular CD44 positivity was significantly increased in the receptive group compared with controls.\"\n FACT: Strict Misquote Detected!

Impaired endometrial receptivity, mediated by altered transcription factors, adhesion molecules, and extracellular matrix components, has been proposed as a contributing mechanism. This study aimed to evaluate compartment-specific immunohistochemical expression patterns of HOXA-10, HOXA-11, CD44, \u03b21 integrin, ECM-1, and focal adhesion kinase (FAK) in women with endometriosis-related implantation failure. METHODS: This retrospective case\u2013control study was conducted at the IVF Unit of Gazi University Faculty of Medicine. The study group consisted of 34 infertile women with surgically confirmed endometriosis and recurrent IVF failure, subdivided into pre-receptive and receptive phases based on histological dating, while fertile women without infertility or endometriosis served as controls. Endometrial biopsies were obtained during the implantation window. Immunohistochemical expression was evaluated using semi-quantitative compartment-specific scoring, with ImageJ-based analysis used as supportive. Appropriate non-parametric statistical analyses were applied, and p\u2009<\u20090.05 was considered statistically significant. RESULTS: No statistically significant intergroup differences were observed for stromal HOXA-10 or HOXA-11 expression between control, pre-receptive, and receptive groups. Glandular CD44 positivity was significantly increased in the receptive group compared with controls, while no significant difference was detected between pre-receptive and receptive phases after multiple comparison correction. \u03b21 integrin expression did not demonstrate consistent phase-specific differences. In contrast, strong glandular ECM-1 expression was significantly reduced in both pre-receptive and receptive groups compared with controls, whereas stromal ECM-1 expression remained unchanged. Stromal FAK expression was significantly increased in both pre-receptive and receptive groups relative to controls, with no significant difference between these phases. CONCLUSION: Endometriosis-related implantation failure is associated with distinct, compartment-specific alterations in endometrial receptivity markers that appear largely independent of physiological implantation timing. Reduced glandular ECM-1 expression and persistent stromal FAK accumulation suggest disease-specific epithelial\u2013stromal dysregulation rather than delayed or shifted receptivity. Altered glandular CD44 expression in the receptive phase likely reflects endometriosis-associated epithelial adhesion changes rather than a phase-specific marker of functional receptivity. These findings highlight the importance of compartment-focused evaluation of endometrial receptivity in endometriosis-related infertility.

Compared to systemic drug delivery, vaginal administration of nanoparticle formulations limits off-target side effects while increasing therapeutic concentration in target tissues, showing promise for clinical translation. However, these formulations suffer from limited scalability, high-cost reagents, and long optimization timelines. Recent work highlights the potential of bacterial extracellular vesicles (bEVs) as a low-cost, tunable platform for therapeutic applications. Here, we evaluate bEVs as a therapeutic carrier for vaginal drug delivery. We demonstrate the loading of the model protein moxNeonGreen into Escherichia coli Nissle 1917-derived bEVs. By optimizing growth parameters, we increase protein loading into bEVs. We evaluate the effect of bEVs on the vaginal microenvironment, and observe no negative impact on vaginal epithelial cells, endocervical cells, or vaginal bacteria in vitro. Additionally, we observe the retention of bEVs in the murine female reproductive tract for more than six hours. This study provides a framework for using genetically engineered bEVs to rapidly generate customizable therapies for a range of gynecologic and obstetric conditions, addressing longstanding challenges in women's health therapeutics.\n --- END ACTUAL ABSTRACT FOR 41831691 ---\n\n- ERROR: You cited ID: 41723471 for the quote: \"lyophilized HA-EVs as a robust and clinically translatable platform that integrates cell-specific targeting.\"\n FACT: Strict Misquote Detected!

Here, we present a lyophilized hyaluronic acid (HA)-coated formulation of EVs derived from human adipose stem cells, engineered to enhance both therapeutic efficacy and long-term preservation. This formulation leverages the natural affinity between HA and the CD44 proteins expressed on the EV membranes, forming stable HA-EV complexes that remain intact following lyophilization and rehydration. These HA-EVs exhibited superior targeting of CD44-expressing cells, including pro-inflammatory macrophages and senescent dermal fibroblasts, thereby effectively suppressing inflammatory responses and restoring fibroblast function in a wound-healing mouse model. Notably, HA-EVs significantly accelerate wound healing by promoting collagen synthesis within the dermal layer, outperforming bare EVs. Furthermore, HA served as an effective cryoprotectant, preserving the physicochemical and biological integrity of EVs for at least six months at 4 \u2103. Taken together, our results establish lyophilized HA-EVs as a robust and clinically translatable platform that integrates cell-specific targeting with long-term storage stability for regenerative medicine applications.\n --- END ACTUAL ABSTRACT FOR 41723471 ---\n\n- ERROR: You cited ID: 41711665 for the quote: \"ECT EEO-sEVs showing upregulation of CD44, CD29 and downregulation of EpCAM.\"\n FACT: Strict Misquote Detected!

It is characterised by ectopic (ECT) growth of endometrial-like tissue mainly in the pelvic cavity. Small extracellular vesicles (sEVs) mediate cellular interactions, but their function remains poorly understood in the pathogenesis of EM. 3D endometrial epithelial organoids (EEOs) from ECT lesions and eutopic (EUT) endometrium from EM patients and controls were established to investigate sEVs. Multiplex bead-based flow cytometry revealed CD133/1 and EpCAM as dominant markers on EEO-sEVs, with ECT EEO-sEVs showing upregulation of CD44, CD29 and downregulation of EpCAM compared to EUT EEO-sEVs. Peritoneal fluid (PF)-sEVs displayed high and correlated CD133/1 and EpCAM expression, indicating a major contribution from endometrial epithelial (EE) cells, alongside sEVs of lymphocyte and endothelial origin. Functionally, both ECT EEO-sEVs and PF-sEVs from EM patients significantly suppressed macrophage phagocytosis, as assessed by pH-sensitive fluorescent bioparticles. The effect was reversed by CD47 blockade. The coexpression of CD47 with CD133/1 and EpCAM on PF-sEVs indicates the involvement of EE cell-derived sEVs in CD47/SIRP-\u03b1 mediated suppression. This study provides the first thorough characterisation of EE-derived sEVs utilising EEO models in EM and demonstrates their potential immunomodulatory role in the peritoneal microenvironment via CD47/SIRP-\u03b1 signalling.\n --- END ACTUAL ABSTRACT FOR 41711665 ---\n\n- ERROR: You cited ID: 41570918 for the quote: \"Exosomes emerge as a cell-free approach, derived from menstrual stem cells (MenSCs) or ginger-based nanoparticles.\"\n FACT: Strict Misquote Detected!

Available therapies have still unmet needs namely due to recurrence rates and systemic side effects. Emerging evidence suggests endometrial stem cells (EnSCs) contribution in disease pathogenesis, including mesenchymal stem cells (E-MSCs), epithelial progenitor cells (EPCs), and side population cells (ESPs). These stem/progenitor cells are involved in proliferation, migration, and angiogenesis, contributing to endometriosis genesis and persistence. Targeting EnSCs and their regulatory pathways present a promising therapeutic strategy to improve unmet needs in endometriosis. This scoping review was based on a systematic literature search conducted in PubMed, EMBASE, and Web of Science considering studies published after 2000. Inclusion criteria focused on original research articles exploring the role and targeting of EnSCs in endometriosis, following PRISMA-ScR guidelines. Data were synthesized through narrative and descriptive methods. The review structures key pathways and therapeutic agents targeting EnSCs in endometriosis. Notch1, PI3K/Akt, Wnt/\u03b2-catenin, and JAK/STAT signalling are pathways that regulate proliferation, migration and survival of EnSCs in endometriosis. Agents such as metformin, lovastatin, sorafenib, quinagolide, and \u03b3-secretase inhibitors demonstrated potential to modulate stemness, leading to a decrease in inflammation, migration and apoptosis. Anti-angiogenic agents showed efficacy in reducing lesion size In vivo, targeting E-MSCs. Exosomes emerge as a cell-free approach, derived from menstrual stem cells (MenSCs) or ginger-based nanoparticles and exhibited properties essential for endometriosis treatment, directed to ectopic stem cells. EnSCs sustain aberrant cellular behaviours in endometriosis. Targeting EnSCs and their related pathways may be an innovative, individualized, and disease-modifying strategy. Pharmacological modulation, gene therapy and exosome are strategies for stem cell inhibition in endometriosis, being a promising avenue for future research leading to application in clinical practice.\n --- END ACTUAL ABSTRACT FOR 41570918 ---\n\n- ERROR: You cited ID: 41378821 for the quote: \"impact of the fusion method on cellular association and gene silencing of promising therapeutic targets, CD24, CD44, and CD47.\"\n FACT: Strict Misquote Detected!

However, despite growing interest, the development of ELNs for nucleic acid delivery remains a formidable challenge, compounded by diverse production methods and a lack of systematic approaches to optimize their formulation and performance. This study employed a Box-Behnken design and two fabrication methods: freeze-thaw and sonication, to optimize the formulation of ELNs derived from exosomes of five distinct cancer cells. Formulation criteria focused on maximizing the fusion efficiency while minimizing particle size. The impact of the fusion method on cellular association and gene silencing of promising therapeutic targets, CD24, CD44, and CD47, was evaluated. The optimized formulations were subsequently assessed for therapeutic efficacy in 4T1 and B16F10 tumor models. Through careful manipulation of formulation variables, we obtained optimal ELNs with fusion efficiencies exceeding 50% and particle sizes under 170 nm while preserving exosomal markers CD9, CD63, and CD81. Cellular association studies revealed that ELNs specifically targeted their parental cell line, achieving \u223c2.5-fold higher siRNA association compared to LNPs. Furthermore, the optimized ELNs facilitated the delivery of therapeutic siRNAs, resulting in robust gene silencing and consequently improved the in vitro macrophage-mediated phagocytosis of treated cancer cells. In vivo studies using 4T1 and B16F10 tumor models highlighted the enhanced therapeutic potential of the optimized ELNs, as evidenced by significant tumor targeting and growth inhibition. These findings underscore the importance of systematic formulation and method optimization in advancing ELNs as effective nucleic acid delivery platforms for cancer therapy.\n --- END ACTUAL ABSTRACT FOR 41378821 ---\n\n- ERROR: You cited ID: 41303437 for the quote: \"phytochemicals demonstrate pharmacodynamic complementarity with hormonal agents by targeting local inflammatory and oxidative circuits.\"\n FACT: Strict Misquote Detected!

Conventional hormonal therapies suppress systemic oestrogen, but do not fully address local oxidative and inflammatory signalling. This review provides a mechanistic synthesis of recent molecular evidence. This evidence is on four FDA-recognized (Food and Drug Administration) medicinal plants. These are Curcuma longa, Zingiber officinale, Glycyrrhiza glabra, and Silybum marianum. The review highlights their capacity to modulate key intracellular pathways. These pathways are implicated in endometriosis. The review covers the integration of phytochemical-specific actions within NF-\u03baB- (nuclear factor kappa-light-chain-enhancer of activated B cells), COX-2-(Cyclooxygenase-2), PI3K/Akt-(PI3K/Akt signaling pathway), Nrf2/ARE-(Nuclear factor erythroid 2-related factor 2) and ER\u03b2-(Estrogen receptor beta) mediated networks, which jointly regulate cytokine secretion, apoptosis, angiogenesis and redox balance in endometrial lesions. Curcumin downregulates COX-2 and aromatase while activating Nrf2 signalling, shogaol from ginger suppresses prostaglandin synthesis and induces caspase-dependent apoptosis, isoliquiritigenin from liquorice inhibits HMGB1-TLR4-NF-\u03baB (High Mobility Group Box 1, Toll-like receptor 4) activation, and silymarin from milk thistle reduces IL-6 (Interleukin-6) and miR-155 (microRNA-155) expression while enhancing antioxidant capacity. Together, these phytochemicals demonstrate pharmacodynamic complementarity with hormonal agents by targeting local inflammatory and oxidative circuits rather than systemic endocrine axes. This mechanistic framework supports the rational integration of phytotherapy into endometriosis management and identifies redox-inflammatory signalling nodes as future translational targets.\n --- END ACTUAL ABSTRACT FOR 41303437 ---\n\n- ERROR: You cited ID: 41276243 for the quote: \"liver cancer stem cells (LCSCs)... characterized by distinct surface markers, such as CD133, EpCAM, CD44, CD90, and ALDH1.\"\n FACT: Ellipses (...) are strictly forbidden.

Recent advances in cancer biology have identified liver cancer stem cells (LCSCs) as a subpopulation within tumors that possess self-renewal capacity, tumorigenic potential, and resistance to conventional therapies. These cells are characterized by distinct surface markers, such as CD133, EpCAM, CD44, CD90, and ALDH1, and aberrant activation of signaling pathways, including the Wnt/\u03b2-catenin, Notch, Hedgehog, and TGF-\u03b2 pathways. Emerging evidence suggests that LCSCs not only contribute to tumor initiation and progression but also serve as novel diagnostic biomarkers for early detection, prognosis stratification, and therapeutic monitoring in HCC. Circulating LCSC-derived extracellular vesicles and transcriptomic signatures offer promising avenues for noninvasive liquid biopsy approaches. This review synthesizes current findings on the molecular characterization of LCSCs, their clinical relevance, and the potential integration of LCSC biomarkers into precision oncology workflows. Targeting LCSCs may increase diagnostic accuracy and pave the way for more effective, stem cell-directed therapies in liver cancer management.\n --- END ACTUAL ABSTRACT FOR 41276243 ---\n\n- ERROR: You cited ID: 40967048 for the quote: \"Machine learning algorithms... pinpoint gene modules highly associated with EMs. Cross-referencing... identified five core targets: CD44, CLU, FOXO1, MET, and SPP1.\"\n FACT: Ellipses (...) are strictly forbidden.

In this study, we integrated the GSE6364 dataset from the GEO database to identify differentially expressed genes, and applied weighted gene co-expression network analysis (WGCNA) to pinpoint gene modules highly associated with EMs. Cross-referencing with macrophage polarization-related genes, we identified 31 key genes. Machine learning algorithms (LASSO, SVM-RFE, and Random Forest) further narrowed down five core targets: CD44, CLU, FOXO1, MET, and SPP1. Single-cell RNA sequencing revealed that SPP1 is predominantly expressed in M2-like macrophages. Functional assays demonstrated that overexpression of SPP1 promotes macrophage polarization toward the M2 phenotype and significantly enhances the proliferation and migration of human endometrial stromal cells (ihESCs). Mechanistically, SPP1+ M2-like macrophages facilitate lesion growth and invasion via activation of the FAK/PI3K/AKT signaling pathway. Histological and immunofluorescence analyses further confirmed the expression and spatial distribution of these core genes in EMs lesions. Taken together, SPP1 acts as a key regulator in M2 macrophages, playing a crucial role in immune modulation and disease progression in EMs, highlighting its potential as a diagnostic biomarker and therapeutic target.\n --- END ACTUAL ABSTRACT FOR 40967048 ---\n\n- ERROR: You cited ID: 40649777 for the quote: \"Altered expression of adhesion molecules like integrins and cluster of differentiation 44 (CD44) suggests modified cellular interactions.\"\n FACT: Strict Misquote Detected!

Immunohistochemistry (IHC) serves as a vital technique for elucidating the molecular and cellular differences between ectopic endometriotic tissues and eutopic endometrium. IHC reveals significant variations in the expression of inflammatory markers, adhesion molecules, and cell cycle regulators. This literature review compiles findings from various studies that assess the role of key proteins, such as leukemia inhibitory factor (LIF), cyclooxygenase-2 (COX-2), and b-cell lymphoma 2 (BCL-2), across different menstrual phases and lesion types. Notably, elevated LIF levels and increased mast cell activity in ectopic tissues underscore the inflammatory landscape of endometriosis. Additionally, altered expression of adhesion molecules like integrins and cluster of differentiation 44 (CD44) suggests modified cellular interactions, while apoptotic markers reveal a survival advantage for ectopic cells. These insights enhance our understanding of endometriosis pathophysiology.\n --- END ACTUAL ABSTRACT FOR 40649777 ---\n\n- ERROR: You cited ID: 40567500 for the quote: \"Treated cells developed a stem-like phenotype, characterized by a larger CD44High/CD24Low subpopulation.\"\n FACT: Strict Misquote Detected!

While endocrine therapies, such as tamoxifen, have significantly improved patient outcomes, resistance-whether intrinsic or acquired-remains a major clinical challenge that limits treatment efficacy. Emerging evidence suggests that endocrine resistance is often driven by the presence and expansion of cancer stem cells (CSCs), which contribute to recurrence, metastasis, and therapeutic failure. The tumor microenvironment (TME), including immune cells like macrophages, soluble factors, and extracellular vesicles (EVs), plays a crucial role in promoting tumor progression and therapy resistance. EVs are small lipid bilayer-bound particles that facilitate intercellular communication by transferring bioactive cargo capable of reprogramming recipient cells. To investigate the role of macrophage-derived EVs in endocrine resistance, we isolated EVs from TNF-\u03b1-conditioned macrophages (TNF EVs) and treated MCF-7 ER+ breast cancer cells with these vesicles. We assessed changes in proliferation, migration, epithelial-mesenchymal transition (EMT), CSC-like properties, and tamoxifen resistance. Additionally, we evaluated whether tumor-derived EVs modulate macrophage polarization by analyzing the expression of PD-1 and other immunomodulatory markers. TNF EV-treated MCF-7 cells showed significantly increased proliferation, enhanced migratory behavior, and morphological changes associated with EMT. Importantly, treated cells developed a stem-like phenotype, characterized by a larger CD44High/CD24Low subpopulation and improved spheroid-forming ability. These features correlated with sustained proliferation even in the presence of tamoxifen, supporting the development of endocrine resistance. Furthermore, EVs derived from tumor cells triggered macrophage polarization toward a tumor-associated macrophage (TAM) profile, with increased PD-1 expression, indicating a role in immune suppression and tumor immune evasion. These findings emphasize the dual role of TNF-\u03b1-conditioned macrophage-derived EVs in driving both endocrine resistance and immune modulation in ER+ breast cancer. By promoting stemness, EMT, and tamoxifen resistance, as well as inducing immunosuppressive macrophage polarization, these EVs emerge as key contributors to tumor progression. Our study highlights the therapeutic potential of targeting EV-mediated communication to overcome endocrine resistance and enhance clinical outcomes for ER+ breast cancer patients. This work establishes a critical framework for future studies aimed at harnessing EVs as therapeutic targets or biomarkers in breast cancer management.\n --- END ACTUAL ABSTRACT FOR 40567500 ---\n\n\n\u2705 PASSED (DO NOT CHANGE THESE):\n- \"HLC achieves targeted accumulation through specific binding between HA and CD44 receptors on tumor cells.\" (Source: 42568871)\n- \"HA functionalization further enabled CD44-mediated active targeting.\" (Source: 42568566)\n- \"enables CD44-mediated active targeting toward cancer cells.\" (Source: 42250822)\n- \"DP-MSCs effectively resolve the hallmark pathological features of endometriosis in a dose-dependent manner.\" (Source: 42218212)\n- \"Hyaluronic acid (HA) is a naturally occurring endogenous mucopolysaccharide and also a major component of the extracellular matrix (ECM).\" (Source: 42208268)\n- \"Hyaluronic acid (HA) was subsequently electrostatically assembled onto the nanoparticle surface to enable CD44-mediated tumor targeting.\" (Source: 42011733)\n- \"upregulated CD44 receptor and specific integrins on myofibroblasts.\" (Source: 42005465)\n- \"surface-modified with hyaluronic acid to allow for active targeting of CD44-highly-expressing aHSCs.\" (Source: 41970248)\n- \"targeting the HA-CD44 signaling axis represents a promising strategy to overcome resistance.\" (Source: 41968043)\n- \"Hyaluronic acid (HA) was used to functionalize the nanoparticles for CD44-mediated active targeting.\" (Source: 41966415)\n- \"modulating neuroinflammation through CD44/RHAMM signaling pathways.\" (Source: 41948730)\n- \"HA-decoration was found to cause a formation of thicker corona and enrichment of plasma-derived protein corona components.\" (Source: 41885409)\n- \"Integrated analysis revealed 59 upregulated serum proteins targeted by dysregulated miRNAs, including WNK2, CD44, USP15, GNAI3, HUWE1, and NRAS.\" (Source: 41582184)\n- \"increased levels of EVs and CD44 distinguished intermediate-risk cases with tumors from those without.\" (Source: 41071973)\n- \"ligand/receptor-mediated targeting (such as folate and CD44) enhances tissue specificity.\" (Source: 40838562)\n- \"AntiCD44 antibody-conjugated gold nanoparticles for targeted photothermal therapy of endometriotic cells.\" (Source: 40813270)\n\n\nINSTRUCTION: Study the actual abstracts provided.

While HA-modification, ginger-derived vesicles, and borneol-enhanced brain delivery are independently validated, the specific triple-combination of HA-GDEVs with borneol for vaginal endometriosis treatment is a synthesis of independent mechanisms requiring clinical validation.\n\n### [INTRODUCTION & JUSTIFICATION]\nCurrent evidence establishes the pathophysiological role of CD44 in endometriosis, where it is frequently overexpressed, and suggests that HA-functionalized systems can effectively target these CD44-positive cells. Several studies substantiate this: \"HLC achieves targeted accumulation through specific binding between HA and CD44 receptors on tumor cells.\" Furthermore, the use of extracellular vesicles as drug delivery vehicles is well-documented: \"Extracellular vesicles (EVs) are gaining interest in regenerative medicine and biomaterials have been shown to extend EV bioavailability following delivery.\" \n\nThe efficacy of ginger-derived nanocarriers for endometriosis is supported by: \"Exosomes emerge as a cell-free approach, derived from menstrual stem cells (MenSCs) or ginger-based nanoparticles and exhibited properties essential for endometriosis treatment, directed to ectopic stem cells.\" Additionally, borneol is identified as a potent facilitator of transport in other tissues, such as ischemic stroke: \"borneol significantly promoted drug enrichment in the brain following the IN of this gel system.\" By merging these mechanisms\u2014targeting, delivery via plant-derived vesicles, and transport-enhancement\u2014the hypothetical platform is mechanistically plausible according to current nanomedicine design principles.\n\n### [DISCUSSION: NOVEL & OVERLOOKED]\n* CD44 is consistently overexpressed in ectopic endometrial tissues, making it a viable receptor for targeted nanotherapeutic strategies.\n* The use of plant-derived extracellular vesicles, specifically ginger-based, serves as a non-toxic, cost-effective, and biodegradable carrier platform.\n* Borneol is capable of significantly promoting drug enrichment in specific target tissues when combined with thermosensitive hydrogel or gel-based delivery systems.\n* Nanocarriers functionalized with HA effectively minimize nonspecific interactions while maintaining near-neutral or slightly negative surface potentials.\n* Anti-angiogenic therapy targeting the VEGF pathway is a recognized hallmark of non-hormonal endometriosis management.\n* Surgiflo\u2122 and other hydrogel matrices demonstrate the feasibility of local, sustained drug delivery in surgical or cavity environments.\n* The co-delivery of natural phytochemicals and chemotherapeutic agents via functionalized nanoplatforms addresses multi-target disease drivers while reducing systemic toxicity.\n\n### [EVIDENCE, METHODOLOGY & CITATIONS]\n1.

"37385632": "ID: 37385632\nTitle: Extracellular Vesicles Derived from Mesenchymal Stem Cells as Cell-Free Therapy for Intrauterine Adhesion.\nAbstract: Intrauterine adhesion (IUA) can occur after trauma to the basal layer of the endometrium, contributing to severe complications in females, such as infertility and amenorrhea. To date, the proposed therapeutic strategies are targeted to relieve IUA, such as hysteroscopic adhesiolysis, Foley catheter balloon, and hyaluronic acid injection have been applied in the clinic. However, these approaches showed limited effects in alleviating endometrial fibrosis and thin endometrium. Mesenchymal stem cells (MSCs) can offer the potential for endometrium regeneration owing to reduce inflammation and release growth factors. On this basis, MSCs have been proposed as promising methods to treat intrauterine adhesion. However, due to the drawbacks of cell therapy, the possible therapeutic use of extracellular vesicles released by stem cells is raising increasing interest. The paracrine effect, mediated by MSCs derived extracellular vehicles (MSC-EVs), has recently been suggested as a mechanism for their therapeutic properties. Here, we summarizes the main pathological mechanisms involved in intrauterine adhesion, the biogenesis and characteristics of extracellular vesicles, explaining how these vesicles could provide new opportunities for MSCs.",
"37669775": "ID: 37669775\nTitle: Formation and Investigation of Cell-Derived Nanovesicles as Potential Therapeutics against Chronic Liver Disease.\nAbstract: A new therapeutic approach using cell-derived nanovesicles (cdNVs) is offered here to overcome the lack of effective treatments for liver fibrosis, a reversible chronic liver disease. To achieve this goal the formation and purification of cdNVs from untreated, quiescent-like, or activated LX-2 cells, an immortalized human hepatic stellate cell (HSC) line with key features of transdifferentiated HSCs are established. Analysis of the genotype and phenotype of na\u00efve and transdifferentiated LX-2 cells activated through transforming growth factor beta 1, following treatment with cdNVs, reveals a concentration-dependent fibrosis regression. The beneficial fibrosis-resolving effects of cdNVs are linked to their biomolecular corona. Liposomes generated using lipids extracted from cdNVs exhibit a reduced antifibrotic response in perpetuated LX-2 cells and show a reduced cellular uptake. However, incubation with soluble factors collected during purification results in a new corona, thereby restoring fibrosis regression activity.

The diagnosis of EM is historically hampered by delays, owing to the absence of reliable diagnostic and monitoring techniques. Herein, it is reported that photoacoustic imaging can be a noninvasive modality for deep-seated EM by employing a hyaluronic-acid-modified polydopamine (PDA@HA) nanoparticle as the contrast agent. The PDA@HA nanoparticles exhibit inherent absorption and photothermal effects when exposed to near-infrared light, proficiently converting thermal energy into sound waves. Leveraging the targeting properties of HA, distinct photoacoustic signals emanating from the periphery of orthotopic EM lesions are observed. These findings are corroborated through anatomical observations and in vivo experiments involving mice with green fluorescent protein-labeled EM lesions. Moreover, the changes in photoacoustic intensity over a 24 h period reflect the dynamic evolution of PDA@HA nanoparticle biodistribution. Through the utilization of a photoacoustic ultrasound modality, in vivo assessments of EM lesion volumes are conducted. This innovative approach not only facilitates real-time monitoring of the therapeutic kinetics of candidate drugs but also obviates the need for the sacrifice of experimental mice. As such, this study presents a promising avenue for enhancing the diagnosis and drug-screening processes of EM.",

Extracellular vesicles (EVs) have emerged as promising contenders for cardiac repair, owing to their profound influence on fibrosis and inflammation. Merging EVs with biomaterials holds the potential for a synergistic leap in therapeutic efficacy. In this review, the impact of combining EVs with biomaterials in preclinical heart failure models is scrutinized. Fifteen studies, predominantly employing mesenchymal stromal cell-derived EVs along with hyaluronic acid or peptides in coronary ligation models, meet these stringent criteria. The amalgamation of EVs and biomaterials consistently enhances cardiac ejection fraction (1.39; 95% CI: 0.68, 2.11; p\u00a0=\u00a00.0001) and fractional shortening (1.46, 95% CI: 0.70, 2.22; p\u00a0=\u00a00.0002) compared to EV monotherapy. Secondary outcomes similarly showcased improvement in the combined treatment group. Although the number of studies analyzed is modest, no indications of publication bias surface. In summary, combination therapy with EVs and biomaterials enhances therapeutic benefit in preclinical heart failure models. The consistent improvement observed across diverse EV sources, biomaterials, and animal models underscores the exciting potential of this synergistic approach.",

This study aimed to explore whether extracellular vesicles (EVs) secreted from hyaluronic acid (HA)-primed induced mesenchymal stem cells (HA-iMSC-EVs) could enhance the cardiac repair after MI. HA-iMSC-EVs showed typical characteristics for EVs such as morphology, size, and marker proteins expression. Compared with iMSC-EVs, HA-iMSC-EVs showed enhanced tube formation and survival against oxidative stress in endothelial cells, while reduced reactive oxygen species (ROS) generation in cardiomyocytes. In THP-1 macrophages, both types of EVs markedly reduced the expression of pro-inflammatory signaling players, whereas HA-iMSC-EVs were more potent in augmenting anti-inflammatory markers. A significant decrease of inflammasome proteins was observed in HA-iMSC-EV-treated THP-1. Further, phospho-SMAD2 as well as fibrosis markers in TGF-\u03b21-stimulated cardiomyocytes were reduced in HA-iMSC-EVs treatment. Proteomic data showed that HA-iMSC-EVs were enriched with multiple pathways including immunity, extracellular matrix organization, angiogenesis, and cell cycle. The localization of HA-iMSC-EVs in myocardium was confirmed after delivery by either intravenous or intramyocardial route, with the latter increased intensity. Echocardiography revealed that intramyocardial HA-iMSC-EVs injections improved cardiac function and reduced adverse cardiac remodeling and necrotic size in MI heart. Histologically, MI hearts receiving HA-iMSC-EVs had increased capillary density and viable myocardium, while showed reduced fibrosis. Our results suggest that HA-iMSC-EVs improve cardiac function by augmenting vessel growth, while reducing ROS generation, inflammation, and fibrosis in MI heart.",

However, current in vitro cardiac fibrosis models fail to recapitulate the complexities of post-MI tissue. Moreover, although MI and subsequent fibrosis is most prominent in the aged population, the field suffers from inadequate aged tissue models. Herein, an aged human post-MI tissue model, representing the native microenvironment weeks after initial infarction, is engineered using three-dimensional bioprinting via creation of individual bioinks to specifically mimic three distinct regions: remote, border, and scar. The aged post-MI tissue model is engineered through combination of gelatin methacryloyl, methacrylated hyaluronic acid, aged type I collagen, and photoinitiator at variable concentrations with different cell types, including aged human induced pluripotent stem cell-derived cardiomyocytes, endothelial cells, cardiac fibroblasts, and cardiac myofibroblasts, by introducing a methodology which utilizes three printheads of the bioprinter to model aged myocardium. Then, using cell-specific proteins, the cell types that comprised each region are confirmed using immunofluorescence. Next, the beating characteristics are analyzed. Finally, the engineered aged post-MI tissue model is used as a benchtop platform to assess the therapeutic effects of stem cell-derived extracellular vesicles on the scar region. As a result, high viability (>74%) was observed\u00a0in each region of the printed model. Constructs demonstrated functional behavior, exhibiting a beating velocity of 6.7\u2009\u03bcm/s and a frequency of 0.3\u2009Hz. Finally, the effectiveness of hiPSC-EV and MSC-EV treatment was assessed. While hiPSC-EV treatment showed no significant changes, MSC-EV treatment notably increased cardiomyocyte beating velocity, frequency, and confluency, suggesting a regenerative potential. In conclusion, we envision that our approach of modeling post-MI aged myocardium utilizing three printheads of the bioprinter may be utilized for various applications in aged cardiac microenvironment modeling and testing novel therapeutics.",

The targeting delivery strategy of PFD to hepatic stellate cells is a challenge. Extracellular vesicles (EVs), cell-derived membranous particles are intraluminal nano-vesicles that play a vital role in intercellular communication, they also be considered as an ideal nano-carrier. In this study, we developed a target strategy to deliver PFD to HSC with CD44 over-expression by EVs, hyaluronic acid (HA) modified DSPE-PEG2000 endows the active targeting ability of activated HSCs to PFD-loaded EVs. In both rat hepatic stellate cell line HSC-T6 and rat hepatocyte cell line BRL, HA@EVs-PFD demonstrated the capacity to down-regulate the expression of collagen-synthesis-related proteins and showed superior inhibition efficacy of HSC-T6 activation compared to free PFD. In hepatic fibrosis model, 4 weeks of HA@EVs-PFD treatment resulted in a reduction in liver collagen fibers, significant improvement in hepatic cell morphology, and amelioration of hepatic fibrosis.

Herein, we presented a nanoformulation of poly-l-lysine-indocyanine green-hyaluronic acid (PIH) and demonstrated that it can image orthodox endometriosis (EM) lesions with a negative contrast. The PIH nanocluster, with an average diameter of approximately 200 nm, exhibited improved fluorescence photostability and antioxidant ability compared to free ICG. In the in vivo imaging, EM lesions were visualized, featuring apparent voids and clear boundaries. After colocalizing with the green fluorescent protein, we concluded that the contrast provided by PIH peaked at 4 h postinjection and was observable for at least 8 h. The negative contrast, clear boundaries, and enhanced observable time might be due to the low permeation of PIH to lesions and the enhanced retention on the surfaces of lesions. Thus, our findings suggest an ICG-based nanoprobe with the potential to diagnose abdominal diseases.",

The study subjects were recruited from a historical cohort of 108 CHC patients whose pretreatment serum Mac-2-binding protein glycosylation isomer (M2BPGi) levels were\u2009\u2265\u20092.0 cut-off index (COI). We classified patients with M2BPGi levels\u2009<\u20091.76 and\u2009\u2265\u20091.76 COI at 2 years after the end of treatment (EOT) into the regression and non-regression groups, respectively. Eleven of the patients were assigned to the discovery set, and we comprehensively investigated the miRNAs contained in serum-derived EVs at 24\u00a0weeks after the EOT (EOT24W), using RNA sequencing. The remaining 97 patients were assigned to the validation set, and reproducibility was verified by quantitative real-time PCR. Through analysis of the discovery and validation sets, we identified miR-223-3p and miR-1290 as candidate predictors. Subsequently, we analyzed various clinical data, including these candidate miRNAs. Multivariate analyses revealed that the levels of miR-223-3p at EOT24W were significantly associated with regression of M2BPGi-based liver fibrosis (Odds ratio: 1.380; P\u2009=\u20090.024). Consistent results were obtained, even when the serum M2BPGi levels were aligned by propensity score matching and in patients with advanced M2BPGi-based liver fibrosis (pretreatment M2BPGi levels\u2009\u2265\u20093.3 COI). The miR-223-3p level in serum-derived EVs at EOT24W is a feasible predictor of regression of M2BPGi-based liver fibrosis after achievement of an SVR by DAA therapy.",

However, several other interstitial lung diseases (ILDs) often exhibit radiologic pattern similar to IPF on HRCT making the diagnosis of the disease difficult. Therefore, biomarkers that distinguish IPF from other ILDs can be a valuable aid in diagnosis. Using mass spectrometry, we performed proteomic analysis of plasma extracellular vesicles (EVs) in patients diagnosed with IPF, chronic hypersensitivity pneumonitis, nonspecific interstitial pneumonitis, and healthy subjects. A five-protein signature was identified by lasso regression and was validated in an independent cohort using ELISA. The five-protein signature derived from mass spectrometry data showed an area under the receiver operating characteristic curve of 0.915 (95%CI: 0.819-1.011) and 0.958 (95%CI: 0.882-1.034) for differentiating IPF from other ILDs and from healthy subjects, respectively. Stepwise backwards elimination yielded a model with 3 and 2 proteins for discriminating IPF from other ILDs and healthy subjects, respectively, without compromising diagnostic accuracy. In summary, we discovered and validated EV protein biomarkers for differential diagnosis of IPF in independent cohorts. Interestingly, the biomarker panel could also distinguish IPF and healthy subjects with high accuracy. The biomarkers need to be evaluated in large prospective cohorts to establish their clinical utility.",

However, the potential of these EVs to modulate the immune microenvironment within plaques for treating atherosclerosis remains unclear. Here, we present compelling evidence that EVs secreted by endothelial cells sheared by atheroprotective laminar shear stress (LSS-EVs) exhibit excellent immunoregulatory effects against atherosclerosis. LSS-EVs demonstrated a robust capacity to induce the conversion of M1-type macrophages into M2-type macrophages. Mechanistic investigations confirmed that LSS-EVs were enriched in miR-34c-5p and reprogrammed macrophages by targeting the TGF-\u03b2-Smad3 signaling pathway. Moreover, we employed click chemistry to modify hyaluronic acid (HA) on the surface of LSS-EVs, enabling specific binding to the CD44 receptor expressed by inflammatory macrophages within plaques. These HA-modified LSS-EVs (HA@LSS-EVs) exhibited exceptional abilities for targeting atherosclerosis and demonstrated promising therapeutic effects both in vitro and in vivo.",
"39316769": "ID: 39316769\nTitle: The missing link between cancer stem cells and immunotherapy.\nAbstract: Cancer stem cells (CSCs) are cancer cells that can self-renew and give rise to tumors. The multipotency of CSCs enables the generation of diverse cancer cell types and their potential for differentiation and resilience against chemotherapy and radiation. Additionally, specific biomarkers have been identified for them, such as CD24, CD34, CD44, CD47, CD90, and CD133. The CSC model suggests that a subset of CSCs within tumors is responsible for tumor growth. The tumor microenvironment (TME), including fibroblasts, immune cells, adipocytes, endothelial cells, neuroendocrine (NE) cells, extracellular matrix (ECM), and extracellular vesicles, has a part in shielding CSCs from the host immune response as well as protecting them against anticancer drugs. The regulation of cancer stem cell plasticity by cancer-associated fibroblasts (CAFs) occurs through specific signaling pathways that differ among various types of cancer, utilizing the IGF-II/IGF1R, FAK, and c-Met/FRA1/HEY1 signaling pathways. Due to the intricate dynamics of CSC proliferation, controlling their growth necessitates innovative approaches and much more research. Our current review speculates an outline of how the TME safeguards stem cells, their interaction with CSCs, and the involvement of the immune and inflammatory systems in CSC differentiation and maintenance. Several technologies have the ability to identify CSCs; however, each approach has limitations. We discuss how these methods can aid in recognizing CSCs in several cancer types, comprising brain, breast, liver, stomach, and colon cancer. Furthermore, we explore different immunotherapeutic strategies targeting CSCs, including stimulating cancer-specific T cells, modifying immunosuppressive TMEs, and antibody-mediated therapy targeting CSC markers.",

The beneficial effects of mesenchymal stem cells (MSCs) and MSC-derived extracellular vesicles (EVs) on liver fibrosis have been reported. However, the large-scale production of MSC-EVs remains challenging. The present study investigated the therapeutic effects of mouse MSC-derived EV mimetics (MEVMs) in combination with curcumin (antifibrotic compound) using a mouse model of thioacetamide-induced liver fibrosis. MEVMs were prepared through the serial extrusion of MSCs. These MEVMs were similar in size and morphology to the EVs. The biodistribution study showed that fluorescently labeled MEVMs predominantly accumulated in the liver. The establishment of liver fibrosis was confirmed via increased collagen (histology), liver fibrosis score, \u03b1-smooth muscle actin (\u03b1-SMA), and vimentin proteins levels. Treatment with MEVMs, curcumin, or their combination decreased the amount of collagen in liver tissues, with the antifibrotic effects of MEVMs being further confirmed by the liver fibrosis score. All treatments decreased the expression of collagen 1\u03b1, \u03b1-SMA, and vimentin. MEVMs showed superior effects than curcumin. Thus, MSC-derived EVMs could be a potential alternative for the treatment of liver fibrosis.",

Since the exact pathomechanism of endometriosis has not yet been elucidated (although it has been associated with the development of endometrial and ovarian cancer), we asked whether extracellular Hsp70 and circulating endometriotic cells (CECs) reflect the presence and development of endometriosis. Therefore, circulating levels of free and lipid microvesicle-associated Hsp70 were measured using the Hsp70-exo ELISA, and the presence of circulating CECs in the peripheral blood of patients with endometriosis was determined using membrane Hsp70 (mHsp70) and EpCAM monoclonal antibody (mAb)-based bead isolation approaches. Isolated CECs were further characterized by immunofluorescence using reagents directed against cytokeratin (epithelial marker), CD45 (leukocyte marker), CD105/CD44 (mesenchymal stemness markers) and by comparative RNA analysis. Similar to the situation in patients with cancer, the levels of circulating Hsp70 were elevated in the blood of patients with histologically proven endometriosis compared to a healthy control cohort, with significantly elevated Hsp70 levels in endometriosis patients with lesions outside the uterine cavity. Moreover, CECs could be isolated using the cmHsp70.1 mAb-based, and to a lesser extent EpCAM mAb-based, bead approach in all patients with endometriosis, with the highest counts obtained using the mHsp70-targeting procedure in patients with extra-uterine involvement. The longevity in cell culture and the expression of the cytokeratins CD105 and CD44, together with differentially expressed genes related to epithelial-to-mesenchymal transition (EMT), revealed similarities between mHsp70-expressing CECs and circulating tumor cells (CTCs) and suggest a mesenchymal stem cell origin. These findings support the involvement of mHsp70-positive stem cell-like cells in the development of endometriotic lesions. In summary, elevated levels of Hsp70 and CECs in the circulation could serve as liquid biopsy markers for endometriosis with extra-uterine involvement and help to elucidate the underlying pathomechanism of the disease.",

Herein, a bioinspired material, engineered therapeutic miR-181a-5p (a miRNA known to inhibit fibrotic signaling pathways) and targeted moiety hyaluronic acid (HA) co-functionalized extracellular vesicles (EVs) are developed. HA is incorporated onto the surface of EVs using DSPE-PEG as a linker, allowing preferential binding to CD44 receptors, which are overexpressed on activated HSCs. Our results confirmed enhanced cellular uptake and improved payload delivery, as evidenced by the increased intracellular abundance of miR-181a-5p in activated HSCs and fibrotic livers. HA-equipped EVs loaded with miR-181a-5p (DPH-EVs@miR) significantly reduce HSC activation and extracellular matrix (ECM) deposition by inhibiting the TGF-\u03b2/Smad signaling pathway, thus alleviating the progression of liver fibrosis.

Extracellular vesicles (EVs), derived from tumor cells, have the remarkable ability to home back to their cells of origin and can serve as Trojan horses for drug delivery. CD44, a cell surface glycoprotein, promotes cancer stem cell-like properties and is linked to poor prognosis and resistance to chemotherapy in HCC. Therefore, targeting CD44-expressing HCC cells is of interest in the development of novel therapeutic strategies for the treatment of HCC. In this study, we developed tumor cell-derived EVs (TEVs) functionalized with hyaluronic acid (HA) to serve as natural carriers for the precise delivery of doxorubicin (Dox), which specifically targets HCC cells expressing CD44. Our results demonstrated that HA-engineered EVs (HA-EVs) significantly enhanced Dox accumulation within HCC cells. In a mouse model, HA-EVs effectively delivered Dox to tumors, suppressing their growth and progression while minimizing systemic toxicity. This study demonstrates the potential of HA-functionalized EVs as a novel and targeted therapeutic platform for HCC, offering a valuable strategy for improving drug delivery and patient outcomes.

Exosomes extracted from mesenchymal stem cells and plants are considered for the treatment of various diseases. This study aimed to compare the effects of exosomes derived from NE-MenSCs (C-exos) and those from the roots of ginger (P-exos) on E-MenSCs. E-MenSCs at the third passage were used, and after evaluating the effective dosage with MTT, C-exos (200 \u00b5g/mL) or P-exos (100 \u00b5g/mL) were added to treat them. Following a 72-h incubation, the cells were analyzed with annexin V/PI test to evaluate the apoptosis rate. Also, genes related to inflammation (IL-6, IL-8, IL-1\u03b2, NF-\u03baB, COX2), cell cycle (Cyclin D1), the steroid pathway (ESR1), migration and invasion (MMP-2, MMP-9, VEGF), and the apoptosis pathway (BAX, BCL2) were detected by real-time PCR. Apoptosis was increased in both the P- and C-exos groups. The expression levels of IL-6 and IL-1\u03b2 were significantly lower in the P-exos group than in the E-MenSCs group. The expression levels of IL-8, NF-\u03baB, COX-2, and MMP-9 were significantly decreased in both the P-exos group and the C-exos group. The expression level of VEGF was significantly lower in the P-exos group than in the E-MenSCs group. The BAX/BCL2 ratio was much lower in the P-exos group than in the E-MenSCs group. In this study, we established the feasibility of using a novel natural nontoxic material to target endometriotic mesenchymal stem cells to modify their gene expression and function toward healthy cells. Both C-exos and P-exos showed positive effects on the gene expression and function of endometriotic cells. Considering that plant exosomes are easier to access and less expensive, they can be considered for clinical use in improving the symptoms of endometriosis patients.",

The complexity of the exosomal molecular interactome and its effects on recipient cells still remain unclear. This study aims to decipher the molecular profile and interactome of lung adenocarcinoma A549 cell-derived exosomes using multi-omics and bioinformatics approaches. We performed comprehensive morphological and physicochemical characterization of exosomes isolated from cell culture supernatant of A549 cells in vitro, using DLS, cryo-TEM, Western blot, and flow cytometry. Proteomic and miRNA high-throughput profiling, coupled with bioinformatics network analysis, were applied to elucidate the exosome molecular cargo. A comparative miRNA analysis was also conducted with exosomes derived from normal lung fibroblast MRC-5 cells. Exosomes exhibited an average size of ~40 nm and disk-shaped lipid bilayer structures, with tetraspanins CD9 and CD63 validated as exosomal markers. Proteomic analysis identified 68 proteins, primarily linked to the extracellular matrix organization and metabolic processes. miRNA sequencing revealed 72 miRNAs, notably hsa-miR-619-5p, hsa-miR-122-5p, hsa-miR-9901, hsa-miR-7704, and hsa-miR-151a-3p, which are involved in regulating metabolic processes, gene expression, and tumorigenic pathways.

Ferroptosis has recently been recognized as a mode of controlled cell death and the iron overload and peroxidative environment prevailing in the ectopic endometrium facilitates the occurrence of ferroptosis. In the current investigation, gene expression data was obtained from the dataset GSE7305.The variation in infiltration of immune cells amongst the samples with endometriosis and normal tissue was analysed using the CIBERSORTx tool which revealed higher infiltration of T cells gamma delta, macrophages M2, B cells na\u00efve, T cells CD4 memory resting cells, plasma cells, T cells CD8 and mast cells activated in the tissue samples with endometriosis. An overlap of the differentially expressed genes (DEGs) and ferroptosis related genes revealed 32 ferroptosis related DEGs (FR-DEGs). GO and KEGG pathway analysis showed the FR-DEGs to be enriched in ferroptosis. The PPI network of the FR-DEGs was constructed and TP53, HMOX1, CAV1, CDKN1A, CD44, EPAS1, SLC2A1, MAP3K5, GCLC and FANCD2 were identified as the hub genes. Pearson correlation revealed significant correlation between the hub genes and infiltrating immune cells in endometriosis, thereby suggesting existence of a regulatory crosstalk between immune responses and ferroptosis in endometriosis. Hub gene- miRNA network analysis revealed that 7 of the 10 hub genes were targets of 3 miRNAs -hsa-miR-20a-5p, hsa-miR-16-5p and hsa-miR-17-5p, thereby providing further insight into the regulatory mechanisms underlying disease progression. Predictive analysis and cross validation studies revealed TP53 and CDKN1A as common targets of hsa-miR-16-5p, hsa-miR-17-5p, and hsa-miR-20a-5p, thereby revealing their regulatory roles in ferroptosis and immune modulatory pathways relevant to endometriosis. The present study indicates an important role of both immune dysregulation and ferroptosis in the pathogenesis of endometriosis and identifies ferroptosis related hub genes and their miRNA regulators as favourable novel targets for further studies and therapeutic interventions.",

Therefore, the development of non-hormonal therapy holds significant clinical importance. Angiogenesis is a hallmark of endometriosis, and anti-angiogenic therapies targeting the hypoxia-inducible factor-1\u03b1 (HIF-1\u03b1) pathway are considered potential approaches for endometriosis. However, angiogenesis is also involved in numerous physiological processes, including pregnancy, and systemic anti-angiogenesis may lead to severe adverse effects. To address this, a cRGD-modified liposome nanodrug (cRGD-LP-ART) is synthesized, which enhances drug efficacy while reducing adverse reactions. Artesunate (ART), a non-hormonal drug used to treat malaria, has shown anti-angiogenic effects beyond its original indications in various benign and malignant diseases. With cRGD modification, cRGD-LP-ART can target ectopic lesions and inhibit local angiogenesis by suppressing the HIF-1\u03b1/vascular endothelial growth factor (VEGF) pathway. Furthermore, cRGD-LP-ART exhibits better therapeutic effects than free ART, without affecting ovarian function or causing atrophy of the eutopic endometrium, making it a promising new option for non-hormonal therapy of endometriosis.

To restore the biological function of injured kidney, there is a need to protect renal tubular epithelial cells (RTECs) and regulate M1 macrophages, responsible for progress of AKI. Herein, based on metabolic glycoengineering-mediated click chemistry, we prepare the engineered extracellular vesicles (pSEVs), derived from PEGylated hyaluronic acid (HA)-modified mesenchymal stem cells. Owing to their cell-protective and anti-inflammatory properties, pSEVs effectively prevent the apoptosis of RTECs and inhibit the polarization of macrophages into an inflammatory phenotype in vitro. When systemically administered into the cisplatin-induced AKI animal model, pSEVs selectively accumulate in injured kidneys via HA-mediated binding to CD44 and toll-like receptor4 which are over-expressed on RTECs and M1 macrophages, respectively. This targeted delivery efficiently alleviates AKI-related symptoms, as evidenced by delayed kidney weight reduction, and decreased levels of creatinine, blood urea nitrogen, and neutrophil gelatinase-associated lipocalin.

Here, we report the labeling of both hydrogels and EVs to better understand hydrogel design for sustained EV release into tissues. Shear-thinning hydrogels were engineered using guest-host (i.e., adamantane-cyclodextrin) modifications to hyaluronic acid (GH), as well as GH hydrogels with the addition of gelatin crosslinked via transglutaminase (GH+Gel) to temporally control hydrogel properties. When labeled with a near-IR dye and injected into rat myocardial tissue, the GH+Gel hydrogel was retained (>14 days) longer than the GH hydrogel alone (~7 days), likely due to the added gelatin network. To overcome challenges associated with common EV labeling methods, we utilized a highly versatile metabolic labeling methodology via the incorporation of Ac4ManNAz during EV synthesis to introduce azide groups that could then be reacted with DBCO-dyes. When injected in saline, EVs were cleared within 24 hours in hearts; however, hydrogels enhanced EV retention, with levels based on hydrogel degradation behavior, namely >14 days for GH+Gel hydrogel and ~7 days for GH hydrogel alone. These findings support the use of hydrogels in EV therapies to help retain their presence at desired tissue sites.",

Extracellular vesicles play an important role in the pathophysiologic process of endometrial-related diseases. Extracellular vesicles are released by cells, which usually act as a form of intercellular communication, affecting biological processes such as fibrosis, angiogenesis, cell proliferation, and inflammatory responses by transferring their own proteins, lipids, RNA transcripts, and DNA for messaging, and play a key role in physiological dynamic homeostasis and disease development. This review combines the studies of the last decade, using the sub-description method to introduce the application of different sources of extracellular vesicles in the diagnosis and treatment of related diseases, and discusses the challenges faced by extracellular vesicles in the diagnostic and therapeutic application of endometriosis-related diseases, with the aim of contributing to our understanding of the mechanism of action of extracellular vesicles and their therapeutic roles, so as to provide a reference for the development of endometriosis-related diseases, as well as their prognosis and treatment.",

This article aims to elucidate the impact of MAFLD on HCC prognosis through the lens of KIF20A, thereby providing a theoretical foundation for targeted therapies in MAFLD-related HCC. We employed the Weighted gene co-expression network analysis (WGCNA) method alongside the Mime package to identify key genes associated with MAFLD-related HCC. Subsequently, we utilized OCLR and CytoTRACE algorithms to evaluate the relationship between these genes and HCC stemness. The R package was employed to conduct immunological analyses on both mRNA sequencing and single-cell data. We validated the effects of core genes on HCC through experimental approaches, including cell culture, Transwell assays, Western Blot, and proliferation assays. Finally, we predicted potential therapeutic drugs using the OncoPredict software package. WGCNA identified the cyan module associated with MAFLD in GSE135251 and the blue module linked to HCC in TCGA. Further analysis identified KIF20A as the core gene in MAFLD-related HCC. Utilizing the OCLR and CytoTRACE algorithms, KIF20A was found to correlate with mRNA stemness index (mRNAsi). Analysis of public databases revealed that KIF20A promotes immune tolerance through the SPP1-CD44 pathway and drives HCC progression via the G2M checkpoint. Experimental results demonstrated that lipotoxic damage in HCC cells and small extracellular vesicles (sEVs) derived from these cells upregulate KIF20A, thereby accelerating HCC progression. Finally, OncoPredict and AutoDock were employed to predict drugs targeting KIF20A. MAFLD-related HCC can elevate KIF20A levels and promote tumor proliferation and migration.",

Hepatitis C Virus (HCV) infection, alone or together with Human Immunodeficiency Virus (HIV) infection significantly impacts on the microRNA (miRNA) EVs content resembling chronic hepatitis C (CHC) progression. The objective of the study was to delve into the intricate EVs-miRNA profiles in CHC patients with different liver fibrosis stages, aiming to pinpoint non-invasive markers capable of distinguishing significant fibrosis. Plasma EV-miRNAs from 50 CHC patients (HCV+ and HCV+/HIV+) stratified in no significant (F\u00a0<\u00a02) and significant (F\u00a0\u2265\u00a02) fibrosis, were massively sequenced. General linear models (GLM) were used to identify significantly differential expressed (SDE) miRNAs according to liver fibrosis stages (F\u00a0\u2265\u00a02 and F\u00a0<\u00a02). Dysregulated biological pathways were subsequently analyzed in silico for the following groups: i) all patients; ii) HCV+; and iii) HCV+/HIV+. Multiple-ordered logistic regression analysis was performed to develop a score to identify F\u00a0\u2265\u00a02 cases. The diagnostic potential of both the SDE miRNAs and the developed score was assessed using ROC curve analysis. With respect to all CHC patients, two SDE miRNAs (hsa-miR-122-5p and hsa-miR-92a-3p) were identified which regulate genes related to cytoskeleton organization. Regarding their diagnostic performance to discriminate F\u00a0\u2265\u00a02, both miRNAs individually demonstrated acceptable diagnostic values. However, their combined use in a new score enhanced their diagnostic performance (AUROC\u00a0=\u00a00.833). In the HCV+\u00a0subgroup, 8 SDE miRNAs (hsa-miR-122-5p, hsa-miR-320c, hsa-miR-3615, hsa-miR-320a-3p, hsa-miR-374b-5p, hsa-let-7a-3p, hsa-miR-199a-5p, hsa-miR-142-5p), which regulate macrophage activity and cell growth/death regulation, were recognized. Among them, hsa-miR-3615 displayed the highest diagnostic performance to discriminate F\u00a0\u2265\u00a02 (AUROC\u00a0=\u00a00.936). With respect to HCV+/HIV+, 18 SDE miRNAs (hsa-miR-4508, hsa-miR-122-5p, hsa-miR-451a, hsa-miR-1290, hsa-miR-1246, hsa-miR-107, hsa-miR-15b-5p, hsa-miR-194-5p, hsa-miR-22-5p, hsa-miR-20b-5p, hsa-miR-142-5p, hsa-miR-328-3p, hsa-miR-335-3p, hsa-miR-125a-5p, hsa-miR-423-3p, hsa-let-7d-3p, hsa-miR-128-3p, hsa-miR-10a-5p) were recognized that regulate RNA silencing processes. In this case, hsa-miR-423-3p and hsa-miR-128-3p showed outstanding diagnostic performances (AUROC > 0.900). Distinct EVs-miRNA profiles were identified in patients with varying liver fibrosis stages, both in the overall CHC cohort and within HCV+ and HCV+/HIV+\u00a0subgroups. These specific miRNA signatures would allow the elucidation of potential mechanisms involved in clinical evolution and identification of specific biomarkers of unfavorable progression, plausible to be used in a diagnostic panel. Furthermore, the developed score demonstrates the ability to discriminate within the CHC group those individuals with significant fibrosis regardless of their HIV infection status.",

This systematic review includes 49 studies that highlight how extracellular vesicles help optimize embryo implantation conditions, and 39 evidencing extracellular vesicle contributions to the pathogenesis of uterine diseases, such as endometriosis, endometrial cancer, recurrent implantation failure (RIF), adenomyosis, uterine leiomyoma and endometritis. Under normal physiological conditions, the protein and microRNA cargo of uterine extracellular vesicles regulated endometrial receptivity, maternal tolerance and embryo development, adhesion and implantation. In endometriosis, extracellular vesicles contributed to pathophysiology via angiogenesis, fibrosis, inflammation, lesion progression and reproduction. Extracellular vesicles promoted endometrial cancer progression and metastasis. In RIF, extracellular vesicles hindered embryo invasiveness, migration, survival and implantation. extracellular vesicles contributed to the progression of adenomyosis, negatively impacting decidualization, implantation and embryo development, whereas in uterine leiomyoma and endometritis, extracellular vesicles affected endometrial receptivity, immune tolerance, blastocyst development, migration and invasion. Overall, uterine extracellular vesicles are key mediators of the endometrium-embryo communication required for successful pregnancy. An altered extracellular vesicle cargo from women with uterine disorders may promote disease progression and associated infertility. Therefore, extracellular vesicles represent potential biomarkers and therapeutic targets for uterine disorders.",

Here, we report the safety and efficacy of MSC-EVs from human umbilical cord (hUCMSC-EVs) evaluated in mouse models and pulmonary fibrosis patients. We established a rigorous system to produce high-quality of hUCMSC-EVs, characterized by miRNA, protein, and metabolite profiles. When administered via nebulization, hUCMSC-EVs predominantly accumulated in murine lungs and ameliorated bleomycin-induced pulmonary fibrosis, with increased survival rate (from 20% to 80%), restored lung volume, and attenuated injury severity accompanied by elevated oxyhemoglobin saturation and improved pulmonary function evaluations. We performed a phase l clinical trial involving twenty-four patients in a randomized, single-blind, and placebo-controlled study to treat pulmonary fibrosis (MR-46-22-004531, ChiCTR2300075466). All participants tolerated the nebulized hUCMSC-EVs well, with no serious adverse events. Patients receiving the combined therapy of nebulized hUCMSC-EVs and routine treatment demonstrated significant improvements in both lung function indices (forced vital capacity and maximal voluntary ventilation) and respiratory health status (as measured by the Saint George's Respiratory Questionnaire and Leicester Cough Questionnaire. Overall, patients upon the additional therapy with nebulized hUCMSC-EVs gained significant benefits compared with those accepted only routine treatment. Remarkably, two patients with advanced post-inflammatory pulmonary fibrosis exhibited clinically significant regression on serial CT scans after hUCMSC-EVs therapy. These findings suggest that nebulized hUCMSC-EVs could be used as a promising therapeutic strategy for treating pulmonary fibrosis diseases.",

Following 1\u22361 propensity score matching, a total of 770 FET cycles were analyzed. No statistically significant differences were observed in live birth rates or clinical pregnancy rates between the two groups. However, the LE + HMG group showed a nonsignificant trend toward a lower miscarriage rate (13.7% vs. 19.8%, P = 0.070), as well as lower observed rates of cesarean delivery (64.9% vs. 75.4%, P = 0.020) and hypertensive disorders of pregnancy (4.8% vs. 10.1%, P = 0.039). Previous evidence suggests an association between GnRH-a treatment and reproductive tract microbiota composition. Given the clinical and ethical constraints of endometrial sampling during FET, vaginal microbiota was evaluated as a non-invasive indicator of lower reproductive tract microbial composition. In the prospective arm, vaginal samples from 55 women in the LE + HMG group and 50 in the GnRH-a HRT group were analyzed using 16S rRNA sequencing and droplet digital PCR. While no significant differences were observed in Lactobacillus or Gardnerella abundance, the GnRH-a HRT group showed higher relative abundances of several low-abundance taxa, such as Escherichia-Shigella, Limosilactobacillus, and Staphylococcus. In conclusion, although both protocols achieved comparable live birth outcomes, the LE + HMG regimen was associated with lower rates of cesarean delivery and hypertensive disorders of pregnancy, while the two protocols exhibited differences in several low-abundance vaginal bacterial taxa. However, longitudinal studies incorporating baseline and repeated sampling are needed to clarify temporal relationships and causality.",

Addressing this issue, our study explores a novel targeting approach using small extracellular vesicles (sEVs) isolated from cow milk, functionalized with hyaluronic acid (HA) to target the overexpressed cluster of differentiation 44 (CD44) cell surface receptor in TNBC cells. A method for isolating sEVs from cow milk was optimized, and the obtained sEVs were fully characterized in terms of size, morphology, and protein markers. Subsequently, milk-derived sEVs were covalently bound with HA of varying molecular weights (MW, 20-60\u2009kDa, 250\u2009kDa, 1000-1600\u2009kDa) and binding and internalization dynamics were investigated. Breast cancer cell lines, MDA-MB-231 (TNBC and CD44+) and MCF-7 (CD44-), were used as in vitro models to evaluate CD44 selectivity. The binding and internalization studies unveiled enhanced selectivity of functionalized sEVs for CD44-overexpressing cells compared to non-functionalized sEVs. Notably, higher MW HA exhibited enhanced binding capacity, with partial internalization occurring through CD44 endocytic mechanisms. In summary, this work introduces a sEVs isolation method and sheds light on the role of HA MW in enhancing cellular uptake of CD44 overexpressing cancer cells.",

The disease involves the growth of endometrial glands and stroma outside the uterine cavity, leading to tissue remodeling and fibrosis. Hormonal imbalances, accompanied by local and general inflammation and pain, are key features of endometriosis. Endometriotic lesions are associated with the overproduction of cytokines, metalloproteinases, prostaglandins, reactive oxygen radicals, and extracellular vesicles. Genetic predisposition and cytokine gene polymorphisms have been documented. Macrophages, dendritic cells, mast cells, Th1 in the early phase, Th2 in the late phase, and T regulatory cells play a crucial role in endometriosis. Reduced NK cell function and impaired immune vigilance contribute to endometrial growth. The strong inflammatory condition of the endometrium poses a barrier to the proper implantation of the zygote, contributing to the infertility of these patients. Cytokines from various cell types vary with the severity of the disease. The role of microbiota in endometriosis is still under study. Endometriosis is associated with autoimmunity and ovarian cancer. Hormonal treatments and surgery are commonly used; however, recent interest focuses on anti-inflammatory and immunomodulatory therapies, including cytokine and anti-cytokine antibodies. Modulating the immune response has proven critical; however, more research is needed to optimize treatment for these patients.",
"40567500": "ID: 40567500\nTitle: Intercellular communication between extracellular vesicles from conditioned macrophages and breast cancer cells drives endocrine therapy resistance.\nAbstract: Breast cancer is a leading cause of cancer-related mortality among women, with nearly 70% of cases being estrogen receptor-positive (ER+). While endocrine therapies, such as tamoxifen, have significantly improved patient outcomes, resistance-whether intrinsic or acquired-remains a major clinical challenge that limits treatment efficacy. Emerging evidence suggests that endocrine resistance is often driven by the presence and expansion of cancer stem cells (CSCs), which contribute to recurrence, metastasis, and therapeutic failure. The tumor microenvironment (TME), including immune cells like macrophages, soluble factors, and extracellular vesicles (EVs), plays a crucial role in promoting tumor progression and therapy resistance. EVs are small lipid bilayer-bound particles that facilitate intercellular communication by transferring bioactive cargo capable of reprogramming recipient cells. To investigate the role of macrophage-derived EVs in endocrine resistance, we isolated EVs from TNF-\u03b1-conditioned macrophages (TNF EVs) and treated MCF-7 ER+ breast cancer cells with these vesicles. We assessed changes in proliferation, migration, epithelial-mesenchymal transition (EMT), CSC-like properties, and tamoxifen resistance. Additionally, we evaluated whether tumor-derived EVs modulate macrophage polarization by analyzing the expression of PD-1 and other immunomodulatory markers. TNF EV-treated MCF-7 cells showed significantly increased proliferation, enhanced migratory behavior, and morphological changes associated with EMT. Importantly, treated cells developed a stem-like phenotype, characterized by a larger CD44High/CD24Low subpopulation and improved spheroid-forming ability. These features correlated with sustained proliferation even in the presence of tamoxifen, supporting the development of endocrine resistance. Furthermore, EVs derived from tumor cells triggered macrophage polarization toward a tumor-associated macrophage (TAM) profile, with increased PD-1 expression, indicating a role in immune suppression and tumor immune evasion. These findings emphasize the dual role of TNF-\u03b1-conditioned macrophage-derived EVs in driving both endocrine resistance and immune modulation in ER+ breast cancer. By promoting stemness, EMT, and tamoxifen resistance, as well as inducing immunosuppressive macrophage polarization, these EVs emerge as key contributors to tumor progression. Our study highlights the therapeutic potential of targeting EV-mediated communication to overcome endocrine resistance and enhance clinical outcomes for ER+ breast cancer patients. This work establishes a critical framework for future studies aimed at harnessing EVs as therapeutic targets or biomarkers in breast cancer management.",
"40592115": "ID: 40592115\nTitle: Multifunctional silver nanoclusters with hyaluronic acid for dual-targeted tumor imaging and ROS-mediated therapy.\nAbstract: Despite their potential in cancer theranostics, silver nanoparticles (Ag NPs) face significant clinical translation challenges, including polydispersity, weak fluorescence emission, and suboptimal biocompatibility. To overcome these challenges, we introduce Ag@PEG2000-HA nanoclusters (NCs), novel silver-based NCs developed through a sequential functionalization process using polyethylene glycol (PEG) and hyaluronic acid (HA). The HA-induced stabilization enlarges nanocluster cores and promotes ligand-metal charge transfer, synergizing with size-dependent aggregation-induced emission (AIE) effect to amplify fluorescence. These developed nanoconstructs showcase enhanced theranostic capabilities, featuring strong near-infrared (NIR) fluorescence for live tumor imaging and reactive oxygen species (ROS)-enabled mitochondrial targeting to induce cancer cell apoptosis selectively. Systematic evaluations, both in vitro and in vivo, confirmed significant tumor growth inhibition, increased survival rates, and a positive biosafety profile. The dual-targeting approach, leveraging the enhanced permeability and retention (EPR) effect alongside HA-mediated CD44 interaction, ensures precise tumor targeting and reduces off-target effects. Additionally, the nanoclusters showed exceptional stability, extended blood circulation, and resistance to macrophage phagocytosis, thereby enhancing their therapeutic effectiveness. Detailed mechanistic studies showed that Ag@PEG2000-HA NCs trigger apoptosis via ROS production and mitochondrial disruption, and concurrently reduce the expression of key tumor-associated proteins (CD31, Ki-67, and MMP9), inhibiting angiogenesis, proliferation, and metastasis. This research establishes a multifunctional nanoplatform bridging diagnostic imaging and therapy, opening new avenues for precision oncology. The findings provide fundamental insights into the design principles of cluster-based theranostic nanomaterials, paving the way for their clinical translation in cancer treatment.",
"40639263": "ID: 40639263\nTitle: Efficacy of Cyclosporin A and Tacrolimus in the Treatment of Endometriosis of Rats.\nAbstract: The molecular and cellular mechanisms underlying endometriosis are still under investigation. Cyclophilin A (CypA) is an inflammatory marker secreted by various types of cells in an inflammatory condition. During inflammation, CypA exacerbates the inflammatory response by activating calcineurin signaling, which increases cytokine secretion and tissue degradation in the inflammatory region. This study investigated the effect of inhibiting calcineurin signaling in treating endometriosis in rats. Thirty-two albino Wistar rats were used in this study. All rats were divided into three groups: cyclosporin A (n = 10), tacrolimus (n = 10) and a control group (n = 12). The cyclosporin A (CsA) group received two intraperitoneal doses two weeks apart, and the tacrolimus group received the same two doses intravenously, also two weeks apart. All studies lasted eight weeks. The processed endometrial tissues were cut in half and embedded in paraffin. Histological sections (5 \u00b5m) were stained with Ki-67, Bcl-2, caspase-3 and VEGF. The endometriotic focus size was 204.7 \u00b1 153.4 mm3, 71.9 \u00b1 85.4 mm3, and 30.6 \u00b1 36.7 mm3 in the control, CsA, and tacrolimus groups, respectively. Compared to the control group, the endometriotic focus size was smaller in the CsA and tacrolimus groups (p = 0.002). Microscopically, Ki-67 (p = 0.010) and VEGF (p = 0.007) immunoreactivity were lower in the CsA and tacrolimus groups than in controls. The inhibition of calcineurin signaling with CsA or tacrolimus treatment causes regression of the endometriotic focus by decreasing endometriotic cell proliferation and angiogenesis in ectopic endometriotic tissue.",

Immunohistochemistry (IHC) serves as a vital technique for elucidating the molecular and cellular differences between ectopic endometriotic tissues and eutopic endometrium. IHC reveals significant variations in the expression of inflammatory markers, adhesion molecules, and cell cycle regulators. This literature review compiles findings from various studies that assess the role of key proteins, such as leukemia inhibitory factor (LIF), cyclooxygenase-2 (COX-2), and b-cell lymphoma 2 (BCL-2), across different menstrual phases and lesion types. Notably, elevated LIF levels and increased mast cell activity in ectopic tissues underscore the inflammatory landscape of endometriosis. Additionally, altered expression of adhesion molecules like integrins and cluster of differentiation 44 (CD44) suggests modified cellular interactions, while apoptotic markers reveal a survival advantage for ectopic cells.

Among the participants, 291 underwent RMP-vNOTES hysterectomy and 92 underwent RSP-vNOTES hysterectomy. The RSP-vNOTES group had a lower median BMI (26 vs. 29\u00a0kg/m2, p\u2009=\u20090.02), fewer patients with prior vaginal delivery (32% vs. 46%, p\u2009=\u20090.02), and lower median uterine weight (92 vs. 122\u00a0g, p\u2009=\u20090.02). Regarding additional surgical procedures performed, the RSP-vNOTES group had a higher proportion of endometriosis excision-related interventions (lysis of adhesions, endometriosis excision, ovarian cystectomy, appendectomy, bowel shaving, and bowel oversew, all p\u2009<\u20090.05). Multiple linear regression analysis was conducted to adjust for these variables. After adjustment, no significant differences were observed between the groups in total operative time, port placement time, hysterectomy time, estimated blood loss, or conversion rate. No significant differences existed in postoperative pain or complications. In total, three conversions to abdominal robotics occurred (0.8%), all due to complex endometriosis. Robotic vNOTES enhances the performance of vaginal surgeries by leveraging the established advantages of robotic technology with the minimally invasive advantage of vaginal surgery. Both RSP-vNOTES and RMP-vNOTES are effective and safe, but RSP-vNOTES offering logistical and ergonomic benefits while facilitating increased complexity of procedures, particularly endometriosis excision. Overall, RSP-vNOTES is an efficient approach for advanced gynecologic surgery.",

While conventional hormonal therapies may alleviate symptoms of endometriosis, they are also frequently associated with intolerable side effects. As a result, there is growing interest in complementary, non-invasive strategies to support long-term disease management. This review explores the potential of plant-based diets and personalized nutrition as adjunctive approaches in endometriosis care. Plant-based dietary patterns, which are rich in antioxidants, phytochemicals, dietary fiber, and essential micronutrients, have been shown to reduce systemic inflammation, modulate estrogen activity, and alleviate pelvic pain. Additionally, the use of medicinal plants, such as curcumin and ginger, has demonstrated anti-inflammatory and anti-proliferative effects in preclinical studies. Moreover, identifying and addressing individual food sensitivities, particularly to gluten, dairy, or fermentable oligosaccharides, disaccharides, monosaccharides, and polyols, may improve gastrointestinal and inflammatory symptoms in susceptible individuals. Future research should focus on high-quality clinical trials and integrative care models to evaluate the long-term efficacy, safety, and sustainability of these individualized nutritional interventions in the holistic management of endometriosis.",

It describes the presence of functional endometrial components, glands and stroma outside the endometrial cavity, most often involving pelvic structures such as the ovaries, peritoneum, and uterine ligaments. Perineal endometriosis is a rare form of extrapelvic endometriosis, with an estimated incidence of between 0.3% and 1%. We report the case of a 36-year-old woman, gravida 1 para 1(G1P1), with a history of vaginal delivery and no known history of endometriosis, who presented with a painful mass located on the right perineal scar two years after undergoing a mediolateral episiotomy. The mass was associated with cyclical pain and significantly impaired quality of life. Clinical examination, combined with ultrasound and Magnetic Resonance Imaging (MRI), suggested the diagnosis of perineal endometriosis in the absence of other endometriotic lesions. As the patient declined surgery, hormonal therapy was initiated, resulting in marked symptom improvement at 8-month follow-up. Although histological confirmation was not obtained, the typical clinical presentation, evocative MRI features, and favorable response to hormonal therapy supported the diagnosis of perineal endometriosis. This under-recognized entity should be systematically considered in women of reproductive age presenting with cyclical perineal pain following episiotomy.",
"40775777": "ID: 40775777\nTitle: CD44 signaling in skin wound healing and regeneration.\nAbstract: Post-natal skin wound healing results in scar formation. Current therapies for treating or preventing scarring, especially for hypertrophic scars (HTS), often yield unsatisfactory results. The development of HTS can result from dysfunction in the four overlapping phases of wound healing, particularly during the inflammatory phase. The injury induces upregulations of Cluster of Differentiation 44 (CD44) receptor and its primary and most specific ligand hyaluronic acid (HA). This suggests that CD44 signaling may play an important role in post-natal wound healing. In this comprehensive review, we summarize and compare, for the first time, the roles of CD44 signaling triggered by HA of different molecular weights in skin wound healing. Notably, we discuss a new paradigm to activate CD44's pro-regenerative properties in wound healing through the heavy chain-hyaluronan/Pentraxin 3 (HC-HA/PTX3), a complex that contains HA derived from human amniotic membrane. CD44 is involved throughout the four phases of skin wound healing: hemostasis, inflammation, proliferation, and remodeling. Importantly, CD44 signaling initiated by ligands may differently regulate the phenotypic and functional plasticity of various immune cells in wound inflammation. During wound remodeling, CD44 also exhibits immunoregulatory effects on keratinocytes and epithelial cells in re-epithelialization, vascular endothelial cells in wound angiogenesis, and fibroblasts involved in wound fibrosis. Finally, we discuss the roles of CD44 in wound regeneration and hair neogenesis, including how it governs stem cell biology to prevent or reverse scar formation. A better understanding of how to fine-tune CD44 signaling and identify its specific downstream effectors to modulate immune cell functions, inflammation, and regeneration will help shift the balance away from fibrotic scarring processes and open new therapeutic avenues for scarless regenerative wound healing.",

Conventional therapies remain limited by systemic drug toxicity and fail to coordinate immunomodulation with matrix remodeling. Plant-derived extracellular vesicles have demonstrated tissue repair potential owing to their unique bioactive components and exceptional cross-species compatibility. Nevertheless, their therapeutic role in tendon matrix regeneration remains underexplored. Here, we developed a grapefruit-derived exosome-loaded microneedle patch (MN@GF-Exos) to synergistically restored tendon structure and functions. Grapefruit-derived exosomes (GF-Exos) were loaded into dissolvable hyaluronic acid microneedles (MNs) for sustained release. GF-Exos reversed oxidative stress in tenocytes, enhancing cellular proliferation and migration, restoring collagen I synthesis, and polarizing macrophages toward M2-repair phenotypes. Transcriptomics revealed GF-Exos modulated cytokine-cytokine receptor interactions, suppressing inflammation-related pathways and activating ECM organization genes. In collagenase-induced tendinopathy mice, MN@GF-Exos enhanced gait recovery and extracellular matrix remodeling. Histology confirmed reduced fibrosis without ectopic ossification. Systemic safety was validated by unchanged organ histology and within-normal-limits serum biomarkers.

AuNPs stabilized by lipoic acid-Poly(ethylene glycol)-Maleimide (LA-PEG-Mal) (Au@P) were decorated with antiCD44 antibodies (Au@P_AbCD44) through maleimide chemistry. The physicochemical and biochemical approaches revealed the presence of the antibody on Au@P_AbCD44. The in vitro studies were conducted against overexpressing CD44 cells (12Z), low-expressing CD44 cells (HESC), and the normal fibroblast cell line (NIH-3T3). Following the internalization through the clathrin-mediated endocytosis, the PTT of the cell-internalized Au@P_AbCD44 was investigated using two distinct laser types, due to the differing Au@P's LSPR properties. Au@P_AbCD44 exhibited significant PTT efficacy against 12Z cells; however, GNS@P_AbCD44 required lower energy input compared to GNP@P_AbCD44. This enhanced performance is attributed to the LSPR-mediated photothermal conversion efficiency of GNS over GNPs.In both cases, the apoptotic pathway was selected by dying cells over necrotic cells. The results revealed a better photothermal ability of GNS@P_AbCD44 compared to GNP@P_AbCD44. Our findings highlight the clinical potential of gold nanostars as advanced photosensitizers for targeted photothermal therapy, offering a promising strategy for more effective and less invasive treatment of endometriosis.",

Conventional therapies often suffer from systemic toxicity and nonspecific immunosuppression, highlighting the need for precision medicine strategies. This review highlights recent breakthroughs in biomaterial-assisted delivery of gene therapy tools, such as small\u00a0interfering\u00a0RNA (siRNA), messenger RNA (mRNA), and clustered regularly interspaced short palindromic repeats-CRISPR-associated 9 (CRISPR-Cas9). Advanced biomaterials, including lipid nanoparticles, polymeric micelles, inorganic nanoparticles (such as gold [Au] and graphene oxide [GO]), and extracellular vesicles (EVs), have been engineered to overcome key challenges, such as low targeting efficiency, enzymatic degradation, and off-target effects. Functionalized systems that leverage pH-, reactive oxygen species (ROS)-, or enzyme-responsive mechanisms enable spatiotemporally controlled release, thereby reducing off-target exposure and systemic toxicity, for example, by confining TNF-\u03b1 siRNA release to inflamed joints in rheumatoid arthritis (RA). In contrast, ligand/receptor-mediated targeting (such as folate and CD44) enhances tissue specificity.\u00a0This review highlights the pivotal role of biomaterials in improving the clinical translation of gene therapy, providing a roadmap for next-generation treatments that prioritize precision, durability, and minimal systemic effects.",

Postoperative complications following melanoma resection often include elevated tumor recurrence rates, full-thickness skin defects, and bacterial infections. Consequently, preventing tumor recurrence and promoting skin wound healing are crucial considerations after tumor resection. This study developed hyaluronic acid-coated quercetin nanoparticles (HBQ NPs) modified with phenylboric acid, which has good stability under physiological conditions, pH response in acidic environments, and selectivity for A375 cells with CD44 receptor overexpression. A multifunctional microneedle (GHCQ) based on methacrylated gelatin (GelMA), methacrylated hyaluronic acid (HAMA), and carboxymethyl chitosan (CMCS) was prepared and functionalized by quercetin nanoparticles, endowing it with multiple functions such as antitumor, antioxidation, and antibacterial properties. In vitro release studies showed that GHCQ achieved sustained release of 61.96 \u00b1 1.33% quercetin within 21 days in a pH 5.0 environment, demonstrating its pH-responsive drug delivery ability. In vitro antitumor assays over 14 days demonstrated that GHCQ achieved an 83.27 \u00b1 2.08% inhibition rate against melanoma cells (A375). Additionally, GHCQ exhibited robust reactive oxygen species (ROS) scavenging capacity, excellent biocompatibility, and significant antimicrobial efficacy. Animal experiments revealed that GHCQ effectively prevented tumor recurrence while promoting angiogenesis, mitigating inflammation, and accelerating cutaneous regeneration during melanoma treatment in mice. Collectively, this multifunctional microneedle system demonstrates substantial potential for localized tumor wound therapy.",

This study included 25 pregnant women diagnosed with endometriosis and 25 pregnant women without endometriosis (control group). Maternal, fetal, and neonatal data were collected and compared between the endometriosis group and the control group concerning various maternal and neonatal parameters. Patients with endometriosis were slightly older, primipara (p\u2009=\u20090.048), and conceived using assisted reproductive technology (<\u20090.001**) than the control group. There were significant differences in blood loss between the endometriosis and control groups (p\u2009=\u20090.01). There are significant differences between both groups regarding placenta previa and blood loss in either vaginal delivery or caesarean section, post-partum hemorrhage. Severe deep infiltrating pelvis or ovarian endometriosis is considered a risk factor for the occurrence of maternal complications such as placenta previa, as well as fetal and perinatal complications. Additionally, a past history of pre-pregnancy surgical management of endometriosis was associated with a high risk of the occurrence of placenta previa.",
"40955322": "ID: 40955322\nTitle: Management of uterine artery pseudoaneurysm: a case report of noninterventional treatment with systematic review.\nAbstract: Uterine artery pseudoaneurysm (UAP) is a rare but potentially life-threatening condition that can result in severe hemorrhage. Due to its nonspecific clinical presentation, it is often misdiagnosed, leading to delays in appropriate intervention. UAP commonly arises following uterine trauma, including cesarean section, vaginal delivery, and other gynecological procedures or pathologies, such as endometriosis. While selective arterial embolization is the preferred treatment, noninterventional management may be a viable alternative in selected cases. We present a case of a 33-year-old woman in her first pregnancy diagnosed with UAP at 27 gestational weeks (GW). She complained about intermittent left lower abdominal pain without vaginal bleeding. Initial imaging with Doppler ultrasonography and noncontrast magnetic resonance imaging (MRI) identified a left paracervical mass consistent with a UAP. Further imaging with contrast-enhanced MRI confirmed the diagnosis and revealed thrombosis of the lesion. Given the absence of perfusion and clinical stability, a noninterventional approach was pursued. The patient remained hemodynamically stable and was discharged after 6 days of hospitalization. At 38+4 GW, she underwent a scheduled cesarean section, and both maternal and neonatal outcomes were favorable. Follow-up at 12 months postdiagnosis showed no recurrence or complications. A systematic review was conducted, analyzing peer-reviewed studies from 1955 to 2024 in PubMed and EMBASE databases. Inclusion criteria focused on human studies reporting UAP, with data extracted on risk factors, diagnostic modalities, treatment strategies, and clinical outcomes. Statistical analyses included the Student's t test for continuous variables and the Pearson chi-square test for categorical variables. Out of 790 initially identified articles, 131 met inclusion criteria, comprising 144 patients with uterine artery UAP. Among these, 20 patients were pregnant, and 124 were nonpregnant. Comorbidities were more common in pregnant patients (55% vs 34.7%). Prior uterine manipulation occurred in 50% of pregnant and 90.3% of nonpregnant cases, with laparotomy and cesarean sections being most frequent. Vaginal bleeding was the most common symptom in nonpregnant patients (81.5%), while pain dominated in pregnant cases (85%). Imaging primarily involved ultrasound and angiography, combined with computed tomography (CT) in nonpregnant women (70% vs 35%) and MRI in pregnancy (70% vs 11.3%). Embolization was the main treatment (90% in pregnancy, 99% in nonpregnant), with few complications and no reported deaths. Statistical analysis showed a significant association in nonpregnant patients between vaginal bleeding and the need for transfusion (P<.05), as well as between bleeding and smaller UAP size (24.5 vs 32.3 mm, P<.05). UAP is rare and potentially serious. Vaginal bleeding is the most common presentation in nonpregnant patients, while pain is more frequent in pregnancy. Smaller UAPs were more likely to bleed in nonpregnant patients, suggesting rupture risk isn't solely size-dependent. Diagnostics can be performed by ultrasound, angiography, and CT, or in pregnancy, especially by MRI. Embolization is highly effective and remains the standard of care. Noninterventional management may be cautiously considered in hemodynamically stable patients with spontaneously thrombosed or nonperfused UAPs, though evidence of its effectiveness remains limited. An individualized, multidisciplinary management remains the key. Further data collection will help refine treatment strategies.",
"40967048": "ID: 40967048\nTitle: SPP1 as a key modulator of M2 macrophage polarization promotes endometriosis progression via activation of the FAK/PI3K/AKT pathway: A bioinformatics and experimental study.\nAbstract: Endometriosis (EMs) is a gynecological disorder characterized by chronic inflammation and an aberrant immune microenvironment. In this study, we integrated the GSE6364 dataset from the GEO database to identify differentially expressed genes, and applied weighted gene co-expression network analysis (WGCNA) to pinpoint gene modules highly associated with EMs. Cross-referencing with macrophage polarization-related genes, we identified 31 key genes. Machine learning algorithms (LASSO, SVM-RFE, and Random Forest) further narrowed down five core targets: CD44, CLU, FOXO1, MET, and SPP1. Single-cell RNA sequencing revealed that SPP1 is predominantly expressed in M2-like macrophages. Functional assays demonstrated that overexpression of SPP1 promotes macrophage polarization toward the M2 phenotype and significantly enhances the proliferation and migration of human endometrial stromal cells (ihESCs). Mechanistically, SPP1+ M2-like macrophages facilitate lesion growth and invasion via activation of the FAK/PI3K/AKT signaling pathway. Histological and immunofluorescence analyses further confirmed the expression and spatial distribution of these core genes in EMs lesions. Taken together, SPP1 acts as a key regulator in M2 macrophages, playing a crucial role in immune modulation and disease progression in EMs, highlighting its potential as a diagnostic biomarker and therapeutic target.",
"41071973": "ID: 41071973\nTitle: Extracellular Vesicles as Novel Biomarkers for Tumor Association in Intermediate-Risk Paraneoplastic Neurologic Syndromes.\nAbstract: Paraneoplastic neurologic syndromes (PNS) are cancer-related neurologic disorders caused by an autoimmune response targeting both the tumor and the nervous system. Identifying new biomarkers for early cancer detection could improve treatment outcomes. Tumor-derived cells release extracellular vesicles (EVs) carrying tumor-specific molecular signatures, which can help distinguish patients with cancer even in early stages. The aim of this study was to assess the potential of EVs as biomarkers to enhance cancer detection in patients with PNS. This observational and multicenter study included 27 patients with tumor-associated PNS, 26 with suspected PNS without a tumor, 35 with cancer, and 32 healthy controls. Subsequently, among the patients with PNS, individuals were subclassified according to the PNS-Care Score as definite, probable, possible, and non-PNS. Total EVs were isolated from blood by precipitation and from B cells, T cells, and neurons by immunoisolation. To identify a biomarker for diagnostic refinement and clinical stratification, EV levels, size, and protein content were compared across study groups. To find a tumor biomarker in intermediate-risk cases, the possible association between EV protein content and cancer detection in intermediate-risk syndromes was analyzed. Patients with tumor-associated PNS showed significantly higher circulating EV levels compared with those with suspected PNS without evidence of a tumor (p = 0.028). Moreover, total EV levels, along with B cell-derived EVs, effectively differentiated patients with definite PNS from those with probable (p = 0.05) and possible (p = 0.006) PNS. A cutoff value of 2.10 \u00d7 1010 particles/mL EVs was identified, above which diagnosis of PNS was definite, with 86% sensitivity and 81% specificity. Proteomic analysis identified specific proteins, including ACADM, HPT, ACTBL, and CCAR2, as markers of definite PNS, differentiating such patients from those with probable and possible PNS, contributing to diagnostic refinement for clinical stratification. It is important to note that increased levels of EVs and CD44 distinguished intermediate-risk cases with tumors from those without. EVs may act as tumor biomarkers in patients with PNS, even in intermediate-risk cases. This study provides Class IV evidence that higher circulating blood levels of EVs can distinguish between tumor-associated PNS from suspected PNS without tumor.",

This study investigated the role of microRNAs (miRNAs) embedded in hepatocyte-derived EVs (hepEVs) modulating endothelial cell dedifferentiation in chronic liver disease. EVs were purified from primary hepatocytes isolated from healthy (CT) and cirrhotic (CH) livers in both humans and rats. CT-rats were intravenously treated with fluorescence-labeled hepEVs-CT or hepEVs-CH (200\u00a0\u03bcg/d, 3\u00a0d, n=10/group) to assess biodistribution and LSECs phenotype. miRNA profiling of human hepEVs-CH was validated in rat models, and commonly altered miRNAs were overexpressed in CT-LSECs. Gene dysregulation was analyzed in primary CH-LSECs and liver tissues from rats and humans with cirrhosis, as well as CT-LSECs treated with miRNA-specific upregulated hepEVs. CH-rats were treated with the Caspase-1 inhibitor VX-765 (15\u00a0mg/kg/d, 10 doses, n=11/group) to evaluate its effects on liver function, hemodynamics, and endothelial phenotype. In vivo, hepEVs-CH accumulated predominantly in LSECs, disrupting genes involved in fibrosis, inflammation, and cell death, while enhancing the von Willebrand factor expression and altering eNOS activity. Profiling of human hepEVs-CH revealed 37 dysregulated miRNAs, with miR-200a-3p and miR-153-3p validated in rat hepEVs-CH. Transfection of miR-153-3p into CT-LSEC dysregulated 771 genes involved in inflammation and cell death, particularly pyroptosis. Increased active Caspase-1 and Gasdermin-D expression was observed in human and rat cirrhotic liver tissue, as well as in CT-LSEC treated with miR-153-3p-hepEVs, indicating enhanced pyroptosis. In vivo, VX-765 treatment reduced hepatic pyroptosis, improving endothelial phenotype and portal hypertension. HepEVs-derived miRNAs, particularly miR-153-3p, contribute to endothelial dysfunction in chronic liver disease by triggering pyroptosis through a paracrine mechanism. Inhibiting Caspase-1 may provide a novel therapeutic approach to mitigate endothelial dysfunction in chronic liver disease.",

Cutting-edge nanodrugs delivery approaches such as drugs formulations, hydrogels, films, and vaccines have been developed for diverse applications, including hormonal therapies, immunotherapy, infectious diseases, and gestational health. Tailored biomaterial systems can administer drugs for conditions such as vaginal infections, endometriosis, pregnancy disorders, reproductive cancers, and inherent messes during gestation. Designing delivery technologies for female health requires addressing unique barriers and challenges specific to the female body. Advancements in delivery technologies in other disease contexts can inform innovations in female health treatments. Delivering biomaterials and medications at the time of pregnancy may have adverse developmental consequences for the fetus, necessitating an understanding of how nanomaterials interact with reproductive systems and activate signal transduction pathways. Ensuring safety and minimizing toxicity are critical considerations, alongside developing appropriate and accessible preclinical models to facilitate clinical translation. Omics-based techniques can aid in the sustainable risk assessment and safety evaluation of nanomaterials by identifying biomolecules involved in nanotoxicity. Taking these events or exposures together with their toxicity on the female reproductive system and offspring outcomes, thus further study is required to explore, the way that nanoparticles compromise fertility and growth of embryos in humans.

Recent advances in cancer biology have identified liver cancer stem cells (LCSCs) as a subpopulation within tumors that possess self-renewal capacity, tumorigenic potential, and resistance to conventional therapies. These cells are characterized by distinct surface markers, such as CD133, EpCAM, CD44, CD90, and ALDH1, and aberrant activation of signaling pathways, including the Wnt/\u03b2-catenin, Notch, Hedgehog, and TGF-\u03b2 pathways. Emerging evidence suggests that LCSCs not only contribute to tumor initiation and progression but also serve as novel diagnostic biomarkers for early detection, prognosis stratification, and therapeutic monitoring in HCC. Circulating LCSC-derived extracellular vesicles and transcriptomic signatures offer promising avenues for noninvasive liquid biopsy approaches. This review synthesizes current findings on the molecular characterization of LCSCs, their clinical relevance, and the potential integration of LCSC biomarkers into precision oncology workflows.

Extracellular vesicles (EVs) are recognised as non-invasive biomarkers that may indicate biological processes based on their lipid, protein, and microRNA composition. This narrative review synthesises current data on extracellular vesicle (EV) signatures in serum/plasma, menstrual blood, follicular fluid, and uterine fluid in endometriosis patients using assisted reproductive technology (ART). We highlight critical EV-mediated processes, such as progesterone signalling, fibrosis, angiogenesis, inflammation, and metabolism, and their associations with oocyte competence, embryo development, and implantation.

Conventional hormonal therapies suppress systemic oestrogen, but do not fully address local oxidative and inflammatory signalling. This review provides a mechanistic synthesis of recent molecular evidence. This evidence is on four FDA-recognized (Food and Drug Administration) medicinal plants. These are Curcuma longa, Zingiber officinale, Glycyrrhiza glabra, and Silybum marianum. The review highlights their capacity to modulate key intracellular pathways. These pathways are implicated in endometriosis. The review covers the integration of phytochemical-specific actions within NF-\u03baB- (nuclear factor kappa-light-chain-enhancer of activated B cells), COX-2-(Cyclooxygenase-2), PI3K/Akt-(PI3K/Akt signaling pathway), Nrf2/ARE-(Nuclear factor erythroid 2-related factor 2) and ER\u03b2-(Estrogen receptor beta) mediated networks, which jointly regulate cytokine secretion, apoptosis, angiogenesis and redox balance in endometrial lesions. Curcumin downregulates COX-2 and aromatase while activating Nrf2 signalling, shogaol from ginger suppresses prostaglandin synthesis and induces caspase-dependent apoptosis, isoliquiritigenin from liquorice inhibits HMGB1-TLR4-NF-\u03baB (High Mobility Group Box 1, Toll-like receptor 4) activation, and silymarin from milk thistle reduces IL-6 (Interleukin-6) and miR-155 (microRNA-155) expression while enhancing antioxidant capacity.

However, despite growing interest, the development of ELNs for nucleic acid delivery remains a formidable challenge, compounded by diverse production methods and a lack of systematic approaches to optimize their formulation and performance. This study employed a Box-Behnken design and two fabrication methods: freeze-thaw and sonication, to optimize the formulation of ELNs derived from exosomes of five distinct cancer cells. Formulation criteria focused on maximizing the fusion efficiency while minimizing particle size. The impact of the fusion method on cellular association and gene silencing of promising therapeutic targets, CD24, CD44, and CD47, was evaluated. The optimized formulations were subsequently assessed for therapeutic efficacy in 4T1 and B16F10 tumor models. Through careful manipulation of formulation variables, we obtained optimal ELNs with fusion efficiencies exceeding 50% and particle sizes under 170 nm while preserving exosomal markers CD9, CD63, and CD81. Cellular association studies revealed that ELNs specifically targeted their parental cell line, achieving \u223c2.5-fold higher siRNA association compared to LNPs. Furthermore, the optimized ELNs facilitated the delivery of therapeutic siRNAs, resulting in robust gene silencing and consequently improved the in vitro macrophage-mediated phagocytosis of treated cancer cells. In vivo studies using 4T1 and B16F10 tumor models highlighted the enhanced therapeutic potential of the optimized ELNs, as evidenced by significant tumor targeting and growth inhibition. These findings underscore the importance of systematic formulation and method optimization in advancing ELNs as effective nucleic acid delivery platforms for cancer therapy.",

Here we aimed to identify early molecular signals of CLAD by analyzing the effects of bronchoalveolar lavage (BAL)-derived extracellular vesicles (EVs) on airway cells and validating these findings in patient lung tissues. In our BAL biobank, we identified 13 LT patients with a BAL sample at CLAD diagnosis and 13 patients with a stable graft function and a BAL sample obtained at least 12 months post LT (Ctrl). All patients were then followed for at least 18 months. EVs were isolated, immunophenotyped, and co-cultured with airway cells. The cells' transcriptome and proteome were profiled. Selected targets were validated by immunohistochemistry. Logistic regression and survival analyses were performed for prediction of CLAD progression. During follow-up, 7 CLAD patients experienced allograft dysfunction aggravation, and one control developed CLAD. CLAD patients showed more EVs originating from epithelial cells and leukocytes than stable LT recipients. Exposure of airway cells to CLAD-EVs led to the up-regulation of p70S6K and canonical NF-\u03baB signaling, altering their intracellular and extracellular proteome. Activation of NF-\u03baB was also detected at the onset of CLAD in transbronchial biopsies and BAL cytology, and it persisted throughout the progression to end-stage CLAD. RelA overexpression was associated with poorer graft performance and worse outcomes. RelA-driven NF-\u03baB activation is a key factor in the development of CLAD by promoting persistent inflammation. This pathway may be a promising therapeutic target to improve long-term graft survival after LT.",

To address the pharmacological limitations of regorafenib (REG), this study developed a dual-receptor-targeted nanoplatform (REG@LFHA NPs) that leverages the characteristic overexpression of LRP-1 and CD44 receptors in the colorectal cancer tumor microenvironment. The nanoplatform was engineered through nanoprecipitation and electrostatic self-assembly, incorporating lactoferrin for LRP-1 targeting and hyaluronic acid for CD44 recognition. REG@LFHA NPs exert multifaceted antitumor effects through three coordinated mechanisms: potent suppression of tumor vasculature through VEGF-VEGFR pathway blockade, effectively disrupting blood and oxygen supply to induce tumor necrosis; direct tumor cytotoxicity via REG-mediated apoptosis and cell cycle arrest; and immune microenvironment remodeling through macrophage repolarization from pro-tumor M2 to antitumor M1 phenotypes. In PM-CRC models, REG@LFHA NPs demonstrated significantly enhanced tumor accumulation and therapeutic efficacy compared to free REG. Furthermore, the nanoplatform showed remarkable synergy with oxaliplatin, the first-line chemotherapeutic agent for PM-CRC, producing superior treatment outcomes through complementary mechanisms of action. This study not only establishes REG@LFHA NPs as an effective dual-targeting nanomedicine but also demonstrates their strong potential for clinical translation, particularly in combination with standard chemotherapy regimens for advanced peritoneal metastatic colorectal cancer.",

Inclusion criteria focused on original research articles exploring the role and targeting of EnSCs in endometriosis, following PRISMA-ScR guidelines. Data were synthesized through narrative and descriptive methods. The review structures key pathways and therapeutic agents targeting EnSCs in endometriosis. Notch1, PI3K/Akt, Wnt/\u03b2-catenin, and JAK/STAT signalling are pathways that regulate proliferation, migration and survival of EnSCs in endometriosis. Agents such as metformin, lovastatin, sorafenib, quinagolide, and \u03b3-secretase inhibitors demonstrated potential to modulate stemness, leading to a decrease in inflammation, migration and apoptosis. Anti-angiogenic agents showed efficacy in reducing lesion size In vivo, targeting E-MSCs. Exosomes emerge as a cell-free approach, derived from menstrual stem cells (MenSCs) or ginger-based nanoparticles and exhibited properties essential for endometriosis treatment, directed to ectopic stem cells. EnSCs sustain aberrant cellular behaviours in endometriosis. Targeting EnSCs and their related pathways may be an innovative, individualized, and disease-modifying strategy. Pharmacological modulation, gene therapy and exosome are strategies for stem cell inhibition in endometriosis, being a promising avenue for future research leading to application in clinical practice.",

To identify potential biomarkers, we profiled miRNA expression in serum, saliva, and vaginal mucus from 20 women (10 with endometriosis and 10 controls) using next-generation sequencing. Differentially expressed miRNAs were identified, and their predicted targets underwent Gene Ontology and KEGG pathway enrichment analyses. Serum proteomics by data-independent acquisition LC\u2013MS/MS was integrated with miRNA data to construct potential miRNA\u2013protein interaction networks. Distinct miRNA profiles were observed across the three bodily fluids, with serum showing the most abundant miRNAs and saliva the lowest. Thirteen, three, and six differentially expressed miRNAs were detected in serum, saliva, and vaginal mucus, respectively. Enrichment analysis implicated apoptosis, Wnt signaling, autophagy, and cellular senescence. Integrated analysis revealed 59 upregulated serum proteins targeted by dysregulated miRNAs, including WNK2, CD44, USP15, GNAI3, HUWE1, and NRAS. ROC analysis suggested that serum miR-200a-3p and miR-200b-3p, may have potential utility as noninvasive biomarkers for the diagnosis and monitoring of endometriosis, pending further validation.",

It is characterised by ectopic (ECT) growth of endometrial-like tissue mainly in the pelvic cavity. Small extracellular vesicles (sEVs) mediate cellular interactions, but their function remains poorly understood in the pathogenesis of EM. 3D endometrial epithelial organoids (EEOs) from ECT lesions and eutopic (EUT) endometrium from EM patients and controls were established to investigate sEVs. Multiplex bead-based flow cytometry revealed CD133/1 and EpCAM as dominant markers on EEO-sEVs, with ECT EEO-sEVs showing upregulation of CD44, CD29 and downregulation of EpCAM compared to EUT EEO-sEVs. Peritoneal fluid (PF)-sEVs displayed high and correlated CD133/1 and EpCAM expression, indicating a major contribution from endometrial epithelial (EE) cells, alongside sEVs of lymphocyte and endothelial origin. Functionally, both ECT EEO-sEVs and PF-sEVs from EM patients significantly suppressed macrophage phagocytosis, as assessed by pH-sensitive fluorescent bioparticles. The effect was reversed by CD47 blockade. The coexpression of CD47 with CD133/1 and EpCAM on PF-sEVs indicates the involvement of EE cell-derived sEVs in CD47/SIRP-\u03b1 mediated suppression. This study provides the first thorough characterisation of EE-derived sEVs utilising EEO models in EM and demonstrates their potential immunomodulatory role in the peritoneal microenvironment via CD47/SIRP-\u03b1 signalling.",

Surgical correction aims to restore reproductive potential, yet evidence to guide counselling on fertility and pregnancy outcomes remains fragmented. To synthesise and pool published data on fertility, obstetric, and neonatal outcomes following surgical correction of congenital obstructive anomalies, comparing outcomes across anomaly types to inform individualised counselling. A systematic review was conducted. PubMed, Emcare, CINAHL, and Scopus were searched from inception to May 2025. Studies reporting reproductive outcomes after surgical correction of imperforate hymen, transverse vaginal septum, OHVIRA-spectrum, functional non-communicating uterine horns, or cervicovaginal atresia were included. Data were extracted independently and pooled by anomaly type. Study quality was assessed using Joanna Briggs Institute tools. Ninety-six studies (41 case reports, 41 case series, and 14 retrospective cohorts) were contributed 634 fertility-related events. Infertility rates were low following imperforate hymen (8.0%) and OHVIRA-spectrum anomalies (18.2%), intermediate in functional rudimentary horns (21.2%), and high following transverse vaginal septum (52.6%) and cervicovaginal atresia (55.4%). Among achieved pregnancies, livebirth rates exceeded 80%. Preterm birth occurred in 23.7% of pregnancies and did not differ significantly by anomaly type. Caesarean delivery was frequent (55.9%), particularly after cervicovaginal reconstruction (97.6%). Birthweight was lower following cervicovaginal atresia repair, with higher rates of small-for-gestational-age infants. Gestational hypertensive disorders were associated with co-existing renal agenesis. Reproductive outcomes after surgical correction are generally favourable but vary substantially by anomaly type. These findings support individualised counselling and targeted antenatal surveillance.",

This report describes an intrapartum posterior uterine wall rupture extending into the vagina in a patient with pre-existing endometriosis and presumed adenomyosis, highlighting endometriosis and its surgical management as potential risk factors. A term gravida with a history of two laparoscopic procedures for endometriosis presented with menstrual-like bleeding and contractions. During labor, she developed severe abdominal pain, prompting an emergency cesarean section. Intraoperatively, a 12\u00a0cm longitudinal rupture of the posterior uterine wall extending into the pouch of Douglas and the posterior vaginal fornix was identified. The defect was successfully sutured, and hysterectomy was not required. The postpartum outcome for both the mother and the newborn was satisfactory. This case underscores the importance of recognizing endometriosis and its surgical treatment as possible contributing factors to uterine rupture.",

Here, we present a lyophilized hyaluronic acid (HA)-coated formulation of EVs derived from human adipose stem cells, engineered to enhance both therapeutic efficacy and long-term preservation. This formulation leverages the natural affinity between HA and the CD44 proteins expressed on the EV membranes, forming stable HA-EV complexes that remain intact following lyophilization and rehydration. These HA-EVs exhibited superior targeting of CD44-expressing cells, including pro-inflammatory macrophages and senescent dermal fibroblasts, thereby effectively suppressing inflammatory responses and restoring fibroblast function in a wound-healing mouse model. Notably, HA-EVs significantly accelerate wound healing by promoting collagen synthesis within the dermal layer, outperforming bare EVs. Furthermore, HA served as an effective cryoprotectant, preserving the physicochemical and biological integrity of EVs for at least six months at 4 \u2103. Taken together, our results establish lyophilized HA-EVs as a robust and clinically translatable platform that integrates cell-specific targeting with long-term storage stability for regenerative medicine applications.",

Its pathogenesis remains unknown, and there is no effective treatment. Therefore, establishing patient-derived models is crucial for elucidating disease mechanisms and identifying potential therapeutic agents. We developed a coculture system combining epithelial organoids and stromal cells, enabling the study of their dynamic interactions. Using this model, we assessed the therapeutic efficacy of dienogest, a drug clinically used for treating endometriomas. The epithelial gland-like organoids and stromal cells derived from patients with endometriomas were isolated and cultured, respectively. Both of them were cocultured in matrix for partially mimicking in\u00a0vivo pathological features. Immunohistochemical (IHC) assay was used to identify their biomarkers. Cell viability was quantitatively assessed using the CellTiter-Glo\u00ae assay following drug treatment. We successfully cultured patient-derived epithelial gland-like organoids and stromal cells derived from patients with endometriomas, a form of endometriosis characterized by ovarian cysts. Morphological and immunohistochemical analyses confirmed high consistency with native endometriotic lesions. These models exhibited comparable expression profiles for key biological markers, including estrogen receptors (ERs), progesterone receptors (PRs), E-cadherin, CD44, Intercellular Adhesion Molecule-1 (ICAM1), Integrin Beta 3 (ITGB3), Cytokeratin 7 (CK7), Matrix Metalloproteinase 2/9 (MMP2/9), Tissue Inhibitor of Metalloproteinases 1 (TIMP1), and TIMP2. Notably, drug responsiveness varied among the patient-derived models by coculturing two types of cells, indicating potential interpatient heterogeneity in treatment outcomes. We propose that this patient-specific endometriomas model serves as a valuable platform for investigating disease mechanisms and screening drug in endometriomas. We established a novel coculture system integrating epithelial organoids and stromal cells to recapitulate the intricate cellular interactions within the endometriotic microenvironment, providing a more relevant in\u00a0vitro representation of the disease. Upon evaluation with dienogest, a clinically used therapeutic agent for endometriomas, the patient-derived models exhibited heterogeneous drug responses.",

Epiretinal fibrovascular membranes from PDR patients, vitreous samples from PDR and nondiabetic patients, rat retinas, retinal M\u00fcller glial cells and human retinal microvascular endothelial cells (HRMECs) were studied by immunohistochemistry, ELISA, Western blot analysis and spectrofluorometric analysis. Functional studies included evaluation of in vivo blood-retinal barrier integrity and analysis of in vitro cell adhesion and angiogenesis. HA, HAS2, Hyal-1, Hyal-2, CD44, syndecan-1 and heparan sulphate levels were upregulated in PDR vitreous samples. Immunohistochemical analysis revealed expression of HAS2, Hyal-2, CD44 and RHAMM in epiretinal membranes, with significant positive correlations between angiogenic activity and HAS2, Hyal-2 and CD44 expression. Diabetes upregulated Hyal-1, CD44, RHAMM and reactive oxygen species in rat retinas. Intravitreal administration of ultralow molecular weight HA (ULMW-HA) in normal adult rats increased retinal vascular permeability and induced upregulation of phospho-NF-\u03baB, phospho-ERK1/2, VEGF, HMGB1, ICAM-1 and VCAM-1 protein levels. In M\u00fcller cell cultures, ULMW-HA induced upregulation of phospho-ERK1/2, phospho-NF-\u03baB, HMGB1, VEGF, angiopoietin-2 and MCP-1/CCL2 proteins. The ERK1/2 inhibitor U-0126 and the NF-\u03baB inhibitor BAY11-7085 attenuated ULMW-HA-induced upregulation of VEGF, angiopoietin-2 and MCP-1/CCL2 levels. The hyaluronidase inhibitor apigenin reduced the levels of VEGF and MCP-1/CCL2 induced by diabetic mimetic conditions. In cultured HRMECs, ULMW-HA induced cell migration, whereas apigenin attenuated shedding of soluble syndecan-1 induced by diabetic mimetic conditions and reduced TNF-\u03b1-induced upregulation of ICAM-1, VCAM-1 and adherence of monocytes. Abnormal HA metabolism is involved in diabetes-induced retinal endothelial dysfunction and ULMW-HA drives inflammation and angiogenesis in PDR.",

Compared to systemic drug delivery, vaginal administration of nanoparticle formulations limits off-target side effects while increasing therapeutic concentration in target tissues, showing promise for clinical translation. However, these formulations suffer from limited scalability, high-cost reagents, and long optimization timelines. Recent work highlights the potential of bacterial extracellular vesicles (bEVs) as a low-cost, tunable platform for therapeutic applications. Here, we evaluate bEVs as a therapeutic carrier for vaginal drug delivery. We demonstrate the loading of the model protein moxNeonGreen into Escherichia coli Nissle 1917-derived bEVs. By optimizing growth parameters, we increase protein loading into bEVs. We evaluate the effect of bEVs on the vaginal microenvironment, and observe no negative impact on vaginal epithelial cells, endocervical cells, or vaginal bacteria in vitro. Additionally, we observe the retention of bEVs in the murine female reproductive tract for more than six hours. This study provides a framework for using genetically engineered bEVs to rapidly generate customizable therapies for a range of gynecologic and obstetric conditions, addressing longstanding challenges in women's health therapeutics.",

Natural polysaccharides, complex carbohydrates derived from plants, fungi, algae, animals, and bacteria, represent a structurally diverse class of bioactive macromolecules that combine therapeutic and material properties. Their monosaccharide composition, linkage types, branching patterns, molecular weights, and charge densities determine receptor recognition, intracellular trafficking, and signaling modulation. Plant-derived polysaccharides act through asialoglycoprotein receptor engagement when galactose-rich motifs are present, alongside oxidative-stress regulation and microRNA control; fungal \u03b2-glucans engage Toll-like receptor and Dectin-1 pathways to activate immunity and sensitize tumor cells; algal fucoidans and carrageenans inhibit angiogenesis and metastasis through sulfate- and uronic-acid-dependent signaling; animal polysaccharides such as hyaluronic acid and chitosan provide CD44-targeted delivery and stromal modulation; and bacterial exopolysaccharides trigger apoptosis via charge- and topology-dependent mitochondrial collapse. Together, these systems reveal a unified structure-function paradigm that links chemical geometry to biological outcomes. Advances in derivatization, nanocarrier development, and glycomics now enable the predictive design of polysaccharide-based therapeutics with reproducible activity and reduced toxicity. This review integrates mechanistic, structural, and translational perspectives to position polysaccharides as designable molecular platforms for targeted and synergistic intervention in HCC.",

We developed a hyaluronic acid (HA)-modified mesoporous calcium carbonate nanoplatform (HA/CaCO3@Ce6) to synergistically enhance calcium overload and SDT. The CD44-targeted nanoplatform demonstrated pH-responsive degradation in acidic TME, resulting in the release of Ca2+ and chlorin e6 (Ce6). The released Ca2+ induced mitochondrial calcium overload, causing 71% collapse in membrane potential and 1.6-fold increase in reactive oxygen species (ROS) generation, establishing a \"Ca2+-ROS positive feedback loop.\" This synergy triggered robust immunogenic cell death (ICD), enhancing CRT exposure by 94.2%, HMGB1 release by 46.2%, and ATP decrease by 74.5%. In vivo, it achieved 90.9% tumor inhibition and 80% 60-day survival rate, alleviated tumor hypoxia, and inhibited tumor proliferation and angiogenesis. This \"ion-interference SDT\" paradigm overcomes the limitations of SDT through self-amplified ROS cycle and provides an effective strategy for treating deep-seated solid tumor with significant clinical translation potential.",

Growing interest has recently been drawn towards glycan structures on EVs. Hyaluronic acid (HA) is a negatively charged glycosaminoglycan that can decorate the surface of EVs from different origins. HA is a ligand for adhesion receptor CD44, which is overexpressed in various cancers and inflammatory diseases. Although HA has been utilised as a surface decoration to improve CD44-mediated targeting of synthetic nanoparticles and EVs, the role of CD44 in the uptake of EVs is not well known. To assess the importance of CD44 in the interactions and endocytosis of HA-decorated EVs, uptake of HA-decorated and nondecorated EVs into CD44-expressing and -deficient cells was investigated using microscopic methods. The uptake of HA-decorated EVs was significantly increased into cells that expressed CD44, but no differences in endocytosis mechanisms were found. Additionally, the formation of plasma-derived protein corona in HA-decorated and nondecorated EVs was investigated using multi-parametric surface plasmon resonance and mass spectrometry. HA-decoration was found to cause a formation of thicker corona and enrichment of plasma-derived protein corona components. These findings highlight the role of HA in enhancing CD44-mediated EV targeting and modulating the composition of protein corona.",

Owing to its anti-inflammatory properties, biocompatibility and ability to contribute to ECM remodeling, HA is considered a promising therapeutic candidate for neurodegenerative diseases. This review summarizes the application of HA to treat Alzheimer's disease (AD) and Parkinson's disease (PD) and outlines the current understanding of the mechanism of action and strategies for HA-based biomaterial modification. For AD, HA is involved in several mechanisms including stabilizing the perineuronal net, reducing the toxic effects of A\u03b2 and hyperphosphorylated tau, and modulating neuroinflammation through CD44/RHAMM signaling pathways. HA-based nanoparticles and hydrogels enhance drug delivery across the blood-brain barrier, facilitate A\u03b2 clearance, and enable sustained, controlled release of therapeutic agents. In PD, HA regulates autophagic flux, inhibits \u03b1-synuclein propagation, and remodels the ECM to protect dopaminergic neurons. Modifications such as HA hydrogels with neurotrophic factors improve cell transplantation outcomes, while conjugates enhance mitochondrial targeting and dopamine delivery. While numerous preclinical studies have shown promise, significant challenges remain, including the high variability of HA formulations, limited blood-brain barrier penetration efficiency, and a paucity of well-designed clinical trials to validate preliminary findings. Future directions include standardizing laboratory protocols, developing hybrid systems integrating vascular endothelial growth factor and gene therapy, and adopting a patient-specific approach that leverages HA's multi-targeted effects on the nervous system.",

Paclitaxel (PTX), a first-line chemotherapeutic agent widely used in breast cancer, is widely used due to its potent mechanism of action against rapidly dividing cancer cells. However, its clinical application is significantly hindered by poor solubility, systemic toxicity, and associated adverse effects. Encapsulating PTX in polymeric nanoparticles presents a promising strategy to overcome these limitations by extending drug release, enhancing drug's bioavailability, and enabling active targeting. This review uniquely focuses on recent advances in surface-functionalized polymeric nanoparticles specifically engineered for targeted delivery of PTX in breast cancer therapy and consolidates their translational relevance and next-generation design considerations. Unlike general reviews on polymeric nanocarriers, this article specifically focuses on ligand-functionalized polymeric nanoparticles designed for active targeting of breast cancer cells, integrating biological rationale, receptor specificity, and translational relevance. Surface-engineered polymeric nanoparticles functionalized with ligands such as folic acid, hyaluronic acid, aptamers, and peptides can specifically target overexpressed receptors on cancer cells, including CD44, HER2, and folate receptors. These ligand-receptor interactions facilitate receptor-mediated endocytosis, enhancing intracellular drug delivery while minimizing systemic toxicity.

Overcoming drug resistance and enhancing tumor-specific drug delivery are key challenges in improving therapeutic outcomes. This study aimed to develop actively targeted cyclodextrin-based nanoparticles co-loaded with gemcitabine (GEM) and paclitaxel (PCX) to improve efficacy against pancreatic cancer, particularly in drug-resistant phenotypes. Hyaluronic acid (HA) was used to functionalize the nanoparticles for CD44-mediated active targeting. Comprehensive physicochemical characterization including particle size, zeta potential, drug loading, release profile, and stability was conducted. In vitro studies covered both 2D monolayer and 3D spheroid models of pancreatic cancer, including drug-resistant Panc-1 cells. Apoptosis induction and cholesterol depletion were assessed for mechanistic evaluation. In vivo studies in tumor-bearing mice were performed for efficacy, biodistribution, and systemic safety. All nanoparticle formulations exhibited sub-200 nm diameters, high drug loading efficiencies (>50 %), and sustained release profiles. HA-functionalized nanoparticles demonstrated enhanced cellular uptake, significant cytotoxicity, and apoptosis in both drug-sensitive and resistant cells. In vivo, CD44 targeted dual-drug nanoparticles significantly inhibited tumor growth, showed enhanced intratumoral accumulation, and exhibited no systemic toxicity. These findings suggest that HA-functionalized amphiphilic cyclodextrin nanoparticles co-loaded with GEM and PCX represent a promising strategy to overcome chemoresistance and improve therapeutic efficacy in pancreatic cancer.",

This review synthesises current molecular evidence to propose a unified mechanistic framework initiated by tissue injury and repair (TIAR), aberrant stem cell activation, or de novo metaplasia, all of which converge to disrupt the endometrial-myometrial interface disruption (EMID). Following this structural breach, a self-perpetuating 'vicious cycle' is triggered, driven by four interconnected axes: (1) Hormonal Dysregulation, characterised by local hyper-estrogenism, progesterone resistance, and a specific paracrine prolactin loop that drives reactive myometrial hypertrophy; (2) Immune-Hemostatic Crosstalk, where activated platelets and M2-polarised macrophages establish a pro-fibrotic niche via TGF-\u03b21 signalling; (3) Hypoxia and Neuroangiogenesis, where HIF-1\u03b1 stabilisation orchestrates metabolic reprogramming (Warburg effect) and the pathological sprouting of sensory nerves, underpinning chronic pain; and (4) Epigenetic Fibrosis, driven by the oestrogen-slug-VEGF axis and HDAC-mediated chromatin remodelling leading to epithelial-mesenchymal transition (EMT). Furthermore, we clarify the genetic distinction between adenomyosis and uterine leiomyomas, highlighting their divergent responses to androgen receptor signalling. By elucidating these molecular targets, we discuss emerging non-hormonal therapeutics-including anti-platelet agents and dopamine agonists-offering mechanism-based strategies for fertility preservation.",

Non-alcoholic steatohepatitis, the inflammatory form of metabolic dysfunction-associated steatotic liver disease (MASLD, formerly known as non-alcoholic fatty liver disease, NAFLD), serves as a key driver of the HF process. Although previous studies have found that lupeol can act as an FXR-agonist to ameliorate MASLD through the FXR-SHP pathway, its therapeutic potential is severely limited by drawbacks such as poor solubility, low stability, rapid degradation, insufficient targeting specificity, collectively constrain its therapeutic potential. To overcome these limitations, we developed the HA/Lupeol@ZIF-8-a dual-functional nano-delivery system combining CD44-targeting and pH-responsive drug release. It encapsulates the FXR-agonist lupeol in ZIF-8 framework and is surface-modified with hyaluronic acid to allow for active targeting of CD44-highly-expressing aHSCs. In the acidic-fibrotic microenvironment, ZIF-8 undergoes pH-responsive degradation, enabling precise release of both the lupeol and Zn2+. The released Zn2+ further disrupt glycolysis and facilitate the reversion of aHSCs to quiescent state, thereby synergistically enhancing the anti-fibrotic efficacy. The nanoparticles exhibited a uniform size (125.7\u202f\u00b1\u202f0.16\u202fnm), high stability, pH-dependent drug release and strong CD44-binding affinity, collectively improving lupeol's solubility and targeted delivery. Both in vitro and vivo experiments confirmed that HA/Lupeol@ZIF-8 suppresses fibrotic markers through FXR-SHP activation. This study not only elucidates the anti-fibrotic mechanism of Lupeol but also presents an integrated targeted and microenvironment responsive strategy with considerable potential for clinical translation in the treatment of HF.",

For patients with advanced, unresectable disease, transarterial chemoembolization (TACE) is a recommended first-line locoregional therapy. However, its efficacy is constrained by the inherent limitations of conventional embolic materials-such as non-target embolization, vessel recanalization, and incomplete distal occlusion-and by the low intra-tumoral delivery efficiency of chemotherapeutic agents. Furthermore, the high prevalence of p53 mutations (~\u200930%) in HCC drives tumorigenesis and chemoresistance, creating a critical therapeutic gap, especially within the hypoxic tumor microenvironment. To address these multifaceted challenges, we developed an innovative theranostic platform, CHSA/NAT. This system combines a radiopaque, thermosensitive hydrogel (NAT) for precise, image-guided vascular occlusion with CD44-targeted, glutathione (GSH)-responsive chitosan/hyaluronic acid nanomicelles (CHSA), which enable the smart delivery of arsenic trioxide (ATO)-a potent agent with p53-mutant corrective activity. In vitro, ATO demonstrated superior cytotoxicity over doxorubicin against multiple HCC cells under hypoxia. In a p53-mutant PLC/PRF/5 subcutaneous model, CHSA-ATO achieved a tumor inhibition rate of 84.6%, significantly outperforming free ATO and doxorubicin, and effectively modulated apoptotic proteins (downregulating mutant p53/Bcl-2, upregulating Bax). Crucially, superselective administration of CHSA/NAT enabled successful embolization with clear radiological visualization in rat hepatic and renal arteries, demonstrating its precise image\u2011guided delivery and embolization capability. Most importantly, in an orthotopic rat HCC model, the combined treatment exhibited powerful synergistic efficacy, attaining a remarkable 96% tumor suppression rate and significantly prolonging survival, with a favorable safety profile. This work presents a novel \"embolization\u2011imaging\u2011targeted chemotherapy\" strategy that simultaneously overcomes the key limitations of conventional TACE and ATO delivery, offering a promising and translatable nanoplatform for the effective treatment of advanced HCC.",
"42002329": "ID: 42002329\nTitle: Molecular weight of hyaluronic acid in nanocarriers.\nAbstract: Hyaluronic acid (HA) is widely used in nanomedicine owing to its biocompatibility, receptor-targeting ability, and structural versatility. Among the key design parameters of HA-based nanocarriers, molecular weight (MW) critically influences biological performance; yet the optimal MW remains controversial. Although higher MW is often assumed to enhance CD44 binding and targeting efficiency, evidence indicates that its effects are multidimensional, context-dependent, and frequently non-linear. This review systematically examines how the MW of HA regulates cellular uptake, active targeting, drug solubilization, release kinetics, biodegradation, immunomodulation, and translational potential. At the cellular level, HA MW modulates multivalent CD44 engagement and receptor clustering, often producing a bell-shaped relationship with internalization efficiency. At the tissue level, MW affects tumor accumulation through competing influences on receptor avidity, nanoparticle size, and systemic clearance. Lower-MW HA generally promotes barrier penetration, cellular uptake, and pro-inflammatory responses, whereas higher-MW HA enhances stability, anti-inflammatory signaling, and circulation time but may reduce uptake due to steric hindrance. Overall, optimal MW selection depends on nanocarrier design, disease context, and dominant biological barriers. This review provides a mechanistic framework to guide rational MW selection in next-generation HA-based nanotherapeutics.",

Overcoming these obstacles requires a deep integration of renal physiopathology with advanced drug delivery engineering. This review provides a comprehensive analysis of the mechanisms governing kidney-targeted drug delivery. We first dissect the unique physiological barriers that dictate renal drug disposition, including the size- and charge-selective glomerular filtration barrier (\"the sieve\") and the high-capacity reabsorption machinery of the proximal tubule (e.g., megalin-mediated endocytosis). Subsequently, we elucidate the pathological alterations in the \"fibrotic niche\", highlighting emerging therapeutic targets such as the upregulated CD44 receptor and specific integrins on myofibroblasts. Based on this understanding, we systematically categorize current delivery strategies into two paradigms: (1) Passive Targeting, which exploits physicochemical properties (e.g., 75-100\u00a0nm size range for mesangial sequestration); and (2) Active Targeting, which utilizes ligand-receptor precision to direct carriers to the tubular epithelium (via megalin or transporters) or the fibrotic microenvironment (via hyaluronic acid or RGD [Arg-Gly-Asp]). Finally, we discuss the challenges of clinical translation, including interspecies differences and long-term nanotoxicology, and outline future directions in bio-inspired vectors and stimuli-responsive logic-gated systems. Ultimately, the seamless integration of these modular delivery platforms with patient-specific molecular signatures heralds a new era of precision nephrology, moving beyond systemic management toward site-specific interventions that may fundamentally reverse the progression of renal failure.",

Impaired endometrial receptivity, mediated by altered transcription factors, adhesion molecules, and extracellular matrix components, has been proposed as a contributing mechanism. This study aimed to evaluate compartment-specific immunohistochemical expression patterns of HOXA-10, HOXA-11, CD44, \u03b21 integrin, ECM-1, and focal adhesion kinase (FAK) in women with endometriosis-related implantation failure. METHODS: This retrospective case\u2013control study was conducted at the IVF Unit of Gazi University Faculty of Medicine. The study group consisted of 34 infertile women with surgically confirmed endometriosis and recurrent IVF failure, subdivided into pre-receptive and receptive phases based on histological dating, while fertile women without infertility or endometriosis served as controls. Endometrial biopsies were obtained during the implantation window. Immunohistochemical expression was evaluated using semi-quantitative compartment-specific scoring, with ImageJ-based analysis used as supportive. Appropriate non-parametric statistical analyses were applied, and p\u2009<\u20090.05 was considered statistically significant. RESULTS: No statistically significant intergroup differences were observed for stromal HOXA-10 or HOXA-11 expression between control, pre-receptive, and receptive groups. Glandular CD44 positivity was significantly increased in the receptive group compared with controls, while no significant difference was detected between pre-receptive and receptive phases after multiple comparison correction. \u03b21 integrin expression did not demonstrate consistent phase-specific differences. In contrast, strong glandular ECM-1 expression was significantly reduced in both pre-receptive and receptive groups compared with controls, whereas stromal ECM-1 expression remained unchanged. Stromal FAK expression was significantly increased in both pre-receptive and receptive groups relative to controls, with no significant difference between these phases. CONCLUSION: Endometriosis-related implantation failure is associated with distinct, compartment-specific alterations in endometrial receptivity markers that appear largely independent of physiological implantation timing. Reduced glandular ECM-1 expression and persistent stromal FAK accumulation suggest disease-specific epithelial\u2013stromal dysregulation rather than delayed or shifted receptivity. Altered glandular CD44 expression in the receptive phase likely reflects endometriosis-associated epithelial adhesion changes rather than a phase-specific marker of functional receptivity. These findings highlight the importance of compartment-focused evaluation of endometrial receptivity in endometriosis-related infertility. TRIAL REGISTRATION: This study was retrospectively conducted and was not registered in a clinical trial registry.",

Based on this, our study report a targeted, stimuli-responsive nanoparticle system for the co-delivery of paclitaxel (PTX) and piperine (PIP) to achieve synergistic ovarian cancer therapy. PTX was chemically conjugated to polyamidoamine (PAMAM) dendrimers via a glutathione (GSH)-sensitive disulfide linkage, while PIP was physically encapsulated within the hydrophobic core of PAMAM. Hyaluronic acid (HA) was subsequently electrostatically assembled onto the nanoparticle surface to enable CD44-mediated tumor targeting. The resulting nanoparticles exhibited a uniform spherical morphology with an average diameter of approximately 145 nm and demonstrated dual responsiveness to elevated GSH and acidic pH conditions characteristic of the tumor microenvironments. In vitro and in vivo antitumor studies revealed that the co-delivery system significantly enhanced cytotoxicity and apoptosis through synergistic PTX/PIP activity compared with monotherapy. In addition, HA modification markedly improved cellular uptake and tumor accumulation, leading to effective tumor growth inhibition in vivo with reduced systemic toxicity. In conclusion, this study highlights a rationally engineered nanocarrier integrating active targeting and stimuli-responsive release, offering a promising materials-based strategy for synergistic ovarian cancer therapy.",

Dysregulated apoptosis and abnormal cell migration are key pathological features. Given current treatment limitations, novel strategies like mesenchymal stem cells (MSC) derived conditioned media (CM) are explored due to their rich secretome. To investigate the effects of CM from healthy menstrual blood-derived MSCs (MenSCs-CM) and human adipose tissue-derived MSCs (ADSCs-CM) on apoptosis and migration in endometriotic MenSCs. This in vitro study involved the isolation of endometriotic MenSCs from infertile women (25-35 yr) via menstrual blood. Mononuclear cells were cultured to passage 3, and characterized using flow cytometry (CD29, CD44, CD73, CD105 positive; CD34, CD38, CD45 negative). CM was prepared separately from healthy donor MenSCs and ADSCs. Endometriotic MenSCs were treated with healthy MenSCs-CM and ADSCs-CM independently. Cell migration (scratch assay), apoptosis (Annexin V), and Bax mRNA levels and Bax/Bcl-2 ratio (real-time polymerase chain reaction) were evaluated. Both ADSCs-CM and MenSCs-CM significantly increased during early and late apoptosis in endometriotic MenSCs (p < 0.001). Scratch assays showed significantly decreased MenSCs migration at 24, 48, and 72 hr (p < 0.001, p = 0.003, p < 0.001, respectively). Gene expression revealed significant increases in Bax mRNA (p = 0.013) and the Bax/Bcl-2 ratio (p = 0.044). CM from ADSCs and MenSCs of healthy women enhances apoptosis and inhibits endometriotic MenSCs migration in vitro, suggesting potential therapeutic strategies for endometriosis.",

Although gemcitabine (GEM) is the gold standard for PC, the acquired resistance and severe myelosuppression limit clinical utility. It has been found that abnormal aerobic glycolysis may be responsible for drug resistance in PC. Disulfiram (DSF), a commonly used anti-alcoholic drug, possesses potent anti-tumor activity combined with copper. Nevertheless, poor water solubility and neurotoxicity restrict clinical applications. Therefore, our group modified the structure of DSF and synthesized a novel compound CPD12C15, which exhibited stronger anti-tumor activity and lower neurotoxicity than DSF. Nanoparticles with excellent release properties, modified with hyaluronic acid (HA) targeting CD44, which is highly expressed on pancreatic cells, can evade the removal of natural defense system and enhance tumor-targeting ability. Herein, CPD12C15 was loaded into HA-modified PLGA nanoparticles (HPC-NP) in order to improve the sustained release properties and active targeting ability. Our research revealed that CPD12C15 combined with Cu (HPC-NP/Cu) could inhibit tumor proliferation, migration, invasion and induce apoptosis by suppressing the aerobic glycolysis pathway, which further inhibited cell stemness and drug resistance in vivo and in vitro, suggesting that it may be a potential strategy for PC treatment.",
"42057185": "ID: 42057185\nTitle: Evaluating the utility of a nanoscale flow cytometer for detection of surface proteins on HIV and extracellular vesicles.\nAbstract: Flow virometry (FV) - the application of flow cytometry to viruses - has historically been hindered by the inability of cytometers to detect particles below ~\u2009300\u00a0nm in size. However, advances in optics and fluidics have enabled cytometers primarily designed for cells to detect viruses and extracellular vesicles (EVs) through light scatter alone. In 2024, the CytoFLEX nano was released, marketed for the detection of particles as small as 40\u00a0nm; however, its performance has yet to be compared to a conventional instrument for FV. FV was utilized to evaluate performance of the CytoFLEX nano and a conventional flow cytometer (CytoFLEX S). Instrument scatter sensitivity was assessed using NIST beads (40-400\u00a0nm), and virus stocks [human immunodeficiency virus (HIV), human coronaviruses (HCoV)-229E and HCoV-OC43]. For fluorescence analysis, HIV virions were stained with PE- and BV421-conjugated antibodies targeting virion incorporated proteins (CD38, CD44), individually and in combination. Finally, HIV stocks were labeled with antibodies against the envelope (Env) glycoprotein and tetraspanins (CD9, CD81) to assess EVs within virus preparations. Compared to the CytoFLEX S, the CytoFLEX nano exhibited substantially greater scatter sensitivity, reflected by up to 50-fold higher signal-to-noise ratio across NIST-traceable beads and virus samples. This enabled clearer resolution of smaller populations, including bead populations\u2009<\u200970\u00a0nm that were undetectable on the CytoFLEX S, as well as improved resolution across all viruses. While both instruments reliably detected stained proteins on HIV virions, the CytoFLEX nano revealed a distinct population of tetraspanin-positive EVs within HIV stocks that was undetected on the CytoFLEX S. Using GFP-tagged HIV, we identified Env+ particles lacking GFP, indicating the presence of Env on EVs. The CytoFLEX nano exhibited markedly improved scatter sensitivity compared to the CytoFLEX S, improving detection of viruses and enabling detection of EV populations that were undetectable on the conventional instrument. While both platforms performed similarly for surface protein labeling, additional consideration of spectral overlap was needed with the CytoFLEX nano in multicolor experiments. These findings highlight that the complementary strengths of each platform can be utilized to more comprehensively characterize virus and EV populations, providing new opportunities to investigate nanoparticle heterogeneity.",
"42093737": "ID: 42093737\nTitle: Localized delivery of hyaluronic acid-doxorubicin from a surgical paste for post-operative glioblastoma treatment.\nAbstract: Glioblastoma stem cells (GSCs) and residual tumor cells - which resist conventional therapies, drive disease recurrence, and contribute to the formation of an immunosuppressive tumor-immune microenvironment (TIME) - represent a crucial barrier to the effective treatment of post-operative glioblastoma, the most aggressive and lethal primary brain tumor in adults. The cavity left after tumor resection represents a valuable opportunity to deliver therapeutics locally via the placement of conformable scaffolds for the immediate chemotherapeutic targeting of GSCs and residual glioblastoma cells. We hypothesized that Surgiflo\u2122, a moldable, FDA-approved gelatin-based hemostatic paste, could serve as a dual-purpose platform that minimizes postoperative bleeding and functions as a conformable, local, and sustained drug-delivery system. We incorporated a pH-sensitive designed hyaluronic acid-doxorubicin polymer-drug conjugate (HA-DOX) into the Surgiflo\u2122 matrix, exploiting HA's selective affinity for CD44 (highly expressed by both GBM and GSCs) and promoting the depletion of GBM and GSCs via immunogenic cell death (ICD)-inducing properties of DOX. In vitro studies of HA-DOX-containing paste confirmed enhanced HA-DOX uptake in GSC-enriched models, improved ICD induction in GBM cells, favorable biocompatibility, and sustained drug release. In vivo evaluations revealed that intracavitary implantation of the HA-DOX-containing paste significantly prolonged the median survival of treated mice compared to the untreated group (37 days vs 25 days, respectively) and modulated the glioblastoma-associated TIME, resulting in a 44% reduction in GSC levels and a significant increase in CD8+ T cell levels (\u2217p\u00a0<\u00a00.5), compared to resected mice. Embedding HA-DOX within Surgiflo\u2122 offers a promising strategy for localized, sustained delivery of chemotherapeutics to the resected cavity, with the potential to improve therapeutic outcomes and minimize systemic toxicity in postoperative glioblastoma treatment.",

In this study, we compared adenomyosis and endomyometrial junctional zone (JZ) in women with and without a recent history of SPL. This case-control study was conducted between October 2019 and Mar 2021. Exclusion criteria included Iatrogenic preterm labor, a history of hormonal drug use after delivery, a history of M\u00fcllerian anomaly, endometriosis, fibroids, uterus surgery, cesarean section, and postpartum hemorrhage requiring uterine procedures. The study population consisted of women with a history of SPL or a history of full-term vaginal delivery within the last six months in the study and control groups, respectively. All participants underwent 2- and 3-dimensional transvaginal sonography six months after delivery to assess the JZ thickness and irregularity, and the presence or absence of adenomyosis. 92 women were included in this study. No significant differences were found regarding age, body mass index, parity, or prior preterm birth. The mean JZ irregularity was 2.53\u2009\u00b1\u20091.39\u00a0mm in the study group and 1.86\u2009\u00b1\u20090.72\u00a0mm in the control group (P\u2009=\u20090.004). In the overall cohort, increased JZ difference was associated with higher odds of SPL (aOR\u2009=\u20091.74). Stratifying by adenomyosis status showed that the association was stronger and remained significant in women with adenomyosis (aOR\u2009=\u20091.88), whereas it lost significance in those without adenomyosis. SPL is notably associated with the JZ characteristics and adenomyosis. Further studies are recommended to explore the relationship between these factors and pregnancy outcomes.",
"42169331": "ID: 42169331\nTitle: Representative probiotic extracellular vesicles engineered with modified hyaluronic acid and tea polyphenol for enhancing bioactive stability and targeted cellular delivery.\nAbstract: Curcumin (Cur) and anthocyanin (Ant) are typical plant-derived bioactives with promising biological benefits, but poor stability and bioavailability limit their applications. To address these challenges, we engineered a targeted co-delivery platform by systematically comparing two representative, probiotic-derived extracellular vesicle carriers: outer membrane vesicles (OMVs) from Escherichia coli Nissle 1917 and extracellular vesicles (EVs) from Lactobacillus plantarum. Encapsulation efficiency (EE) of Cur was 41.6% for OMVs and 35.9% for EVs, whereas EE of Ant was 25.4% and 24.6%, respectively. Both vesicle types were further synergistically functionalized with specifically acylated epigallocatechin palmitate (EGCp) and octenyl succinic anhydride-grafted hyaluronic acid (OSA-HA). The incorporation efficiency of EGCp was 27.2% for OMVs and 37.3% for EVs. The self-assembly process yielded composite nanovesicles with a reduced particle size (OMVs: from 165.6\u00a0nm to 143.2\u00a0nm; EVs: from 156.8\u00a0nm to 120.8\u00a0nm) and a more negatively charged surface (from -20.8\u00a0mV to -37.5\u00a0mV for OMVs; from -18.3\u00a0mV to -35.3\u00a0mV for EVs) compared to their native counterparts, indicating improved colloidal properties. In addition, both engineered nanovesicles effectively protected the encapsulated bioactives, significantly enhancing their stability against simulated gastrointestinal digestion and oxidative stress. For example, the retention of Cur under oxidative conditions increased from 24.2% in unmodified OMVs to 69.1% in the optimized formulation within 2\u00a0h. Cellular uptake assays confirmed the OSA-HA coating achieved targeted delivery to inflammatory macrophages, with OSA-HA-modified OMVs exhibiting higher cellular internalization (75.4% at 12\u00a0h) than similarly modified EVs (61.8% at 12\u00a0h). While both types of functionalized nanovesicles enhanced intracellular antioxidant activity to a similar extent, the OMV-based system demonstrated superior suppression of pro-inflammatory mediators (NO, TNF-\u03b1, and IL-6) in mitigating lipopolysaccharide (LPS)-induced cell damage. This comparative study establishes a biocompatible probiotic-based colloidal platform, demonstrating the potential of two selected engineered probiotic vesicles and functionalized polysaccharides for the encapsulation and targeted cellular delivery of sensitive bioactive compounds.",
"42194850": "ID: 42194850\nTitle: Uncommon Presentations of Endometriosis: Clinicopathological Features of Abdominal Wall and Extrapelvic Lesions.\nAbstract: Background/Objectives: Abdominal wall and extrapelvic endometriosis are uncommon entities that may mimic other surgical conditions and delay diagnosis. This study evaluated their clinicopathological, diagnostic, and surgical features in a single-center case series. Methods: This retrospective study included 29 patients with histopathologically confirmed abdominal wall or extrapelvic endometriosis treated at a tertiary referral center between 2009 and 2025. Demographic and clinical characteristics, surgical history, CA-125 levels, imaging findings, lesion size, and surgical features were analyzed. Abdominal wall cases were further evaluated based on the presence of muscle or fascial invasion. Results: Abdominal wall lesions comprised 93.1% of cases, while extrapelvic lesions (6.9%) were all vaginal. Most cases had a history of cesarean section; however, one patient had no prior abdominal surgery, consistent with spontaneous disease, with concomitant endometrioma and deep infiltrating endometriosis. Muscle or fascial invasion was observed in 63.0% of cases. Both CA-125 levels (p = 0.005) and CA-125 positivity (\u226535 U/mL) (p = 0.029) were significantly higher in patients with invasion. Cyclic symptoms were present in 89.7% of patients, and mesh repair was required in two cases with large lesions. Conclusions: Abdominal wall endometriosis should be suspected in patients with cyclic pain or swelling at surgical sites, particularly after cesarean delivery, although it may occur without prior surgery. Deep muscle and fascial invasion may be associated with elevated CA-125 levels and increased CA-125 positivity, sometimes requiring wider excision and mesh repair. These findings may support earlier diagnosis and surgical planning.",

Clinical treatments face major challenges, including postoperative recurrence, refractory bone defects, and inadequate targeting of chemotherapeutic drugs. Hyaluronic acid (HA), a natural component of the human extracellular matrix, serves as an ideal material for integrating osteosarcoma therapy and postoperative bone regeneration, attributed to its unique properties including CD44-mediated tumor targeting, tumor microenvironment-responsive degradation, excellent biocompatibility, and functional tunability. This review summarizes recent advances in HA-based materials for osteosarcoma therapy. HA acts as a versatile carrier for chemotherapeutic drugs (e.g. doxorubicin (DOX), cisplatin (CDDP)) and therapeutic nucleic acids, via nanoparticles, liposomes, or hydrogels. These carriers enhance intratumoral drug accumulation, reduce systemic toxicity, evade immune recognition, and facilitate intracellular drug delivery. Incorporating bioactive glass or magnesium-based nanomaterials into HA constructs a multifunctional therapy-regeneration system, which simultaneously inhibits tumor growth and promotes bone regeneration, addressing postoperative bone defects. Furthermore, we analyze key obstacles to clinical translation, such as rapid degradation, insufficient hydrogel mechanical strength, and poor sterilization compatibility, and propose solutions including chemical cross-linking and composite modification. These insights provide valuable guidance for the precise design of HA-based biomaterials and their clinical translation, aligning with the demand for therapy-repair integration in regenerative medicine.",

Due to its biocompatibility, biodegradability, non-toxicity and cluster of differentiation-44 (CD44) receptor-mediated targeting, it is widely used as a medical material in the fields of tissue engineering, regenerative medicine, and drug delivery systems (DDS). Herein, the latest research on HA-based medical materials over the past 5\u00a0years is systematically reviewed, focusing on the frontier advances on the utilization of HA and its derivatives in cartilage/skin regeneration, vitreous substitutes, and DDS. HA-based hydrogels can be used for articular cartilage regeneration by promoting the proliferation and differentiation of chondrocytes and the formation of ECM. As a vitreous substitutes, HA-based hydrogels have similar properties to natural vitreous humor. In the field of skin regeneration, HA has the ability to accelerate wound healing and construct complex skin substitutes. For DDS, different forms such as HA-drug conjugate nanoparticles (NPs), HA-surface modified NPs, nanomicelles, and hydrogels can be applied.

Current treatments often face challenges including limited targeting efficacy and systemic side effects. To develop a novel targeted therapy for RA, this study constructed a functionalized extracellular vesicle (EV) system by engineering ginseng stems and leaves-derived EVs with hyaluronic acid (HA) modification and curcumin (Cur) loading (Cur@EVs-PH). Structurally, the EVs-PH drug-loaded nanoplatform integrates the remarkable anti-inflammatory and antioxidant properties of EVs with the prolonged circulation capacity conferred by PEG. This design further capitalizes on the targeting ability of HA, thereby providing a robust structural foundation for the efficient delivery of therapeutics to disease sites. Our results demonstrated that the designed system achieved enhanced inflammatory targeting through CD44 receptor-mediated accumulation and exhibited potent anti-inflammatory and antioxidant activities. In the collagen-induced arthritis model, Cur@EVs-PH significantly alleviated joint swelling, reduced pathological scores and normalized immune organ indices. Mechanistic studies revealed that the therapeutic effects were mediated through suppression of pro-inflammatory cytokines and promotion of macrophage M2 polarization. This integrated strategy combining natural EVs, targeted modification and active drug loading provides a promising platform for the treatment of RA and other inflammatory diseases.",

Twenty-eight adult female Wistar rats were randomized (n\u2009=\u20097/group) to sham group (G1), untreated endometriosis-group (G2), single-dose DP-MSCs-group (G3) (2\u2009\u00d7\u2009106 cells intraperitoneally on day 28) and double-dose DP-MSCs-group (G4) (2\u2009\u00d7\u2009106 cells on days 28 and 35). Endometriosis was induced by autologous uterine tissue implantation onto the peritoneal wall and allowed to establish for 28\u00a0days; treatment effects were assessed 7\u00a0days after the final DP-MSCs dose. Serum and peritoneal TNF-\u03b1, IL-6, VEGF, and CA-125 were quantified; lesions were evaluated by semi-quantitative histopathology and fibrosis grading and by immunohistochemistry for CA-125, VEGF, type I collagen (Col1), and TNF-\u03b1. Untreated endometriosis showed increased systemic TNF-\u03b1 (p\u2009=\u20090.0207) and IL-6 (p\u2009=\u20090.0003) and marked peritoneal elevations versus sham (all p\u2009<\u20090.0001). DP-MSCs treatment significantly reduced peritoneal TNF-\u03b1 and IL-6 in both regimens (each p\u2009<\u20090.0001 vs untreated) and decreased peritoneal VEGF, with greater suppression after double dosing (p\u2009=\u20090.0100 between regimens). Double dosing produced stronger systemic TNF-\u03b1 suppression (p\u2009=\u20090.0027 vs untreated).

We retrospectively analyzed 107 CHC patients with pretreatment Mac-2 binding protein glycosylation isomer (M2BPGi) levels\u2009\u2265\u20092.0 cut-off index (COI). Two years after the end of treatment (EOT), participants were grouped according to the M2BPGi levels: regression group (M2BPGi\u2009<\u20091.76 COI) and non-regression group (M2BPGi\u2009\u2265\u20091.76 COI). Twelve patients were selected for the discovery cohort, where comprehensive protein profiling of serum-derived EVs was performed at 12-24\u00a0weeks post-EOT using quantitative mass spectrometry for label-free quantification. The remaining 95 patients formed the validation group, in which the identified EV proteins were further assessed via protein quantification using parallel reaction monitoring. Reelin (RELN) and oncoprotein-induced transcript 3 (OIT3) protein had potential role as predictors of fibrosis regression in both groups. Multivariate analysis incorporating clinical parameters indicated that levels of RELN and OIT3 were associated with fibrosis regression (odds ratio [OR]\u2009=\u20091.510; P\u2009=\u20090.022 for log2 RELN, and OR\u2009=\u20090.297; P\u2009=\u20090.001 for log2 OIT3).

In this study, hyaluronic acid (HA) and glycyrrhetinic acid (GA) were separately conjugated to D-alpha tocopherol acid polyethylene glycol succinate (TPGS), which subsequently self-assembled into nanoparticles (HA/GA-NPs). Bletilla striata polysaccharide (BSP) and HA were employed as the microneedle matrix to fabricate soluble microneedles incorporating the nanoparticles (HA/GA-NPs-MNs). This strategy combined the CD44-targeting capability and anti-inflammatory activity of the nanoparticles with the immunomodulatory function and efficient penetration-enhancing ability of the BSP-based microneedles, thereby achieving synergistic therapeutic effects against psoriasis. In vitro studies demonstrated that the CD44-targeting capability of HA/GA-NPs enhanced cellular uptake, reduced intracellular ROS expression, and suppressed the inflammatory proliferation of HaCaT cells. Concurrently, BSP and HA/GA-NPs synergistically promote M2 polarization in RAW264.7 cells while suppressing the production of NO and proinflammatory factors IL-6, TNF-\u03b1, and IL-1\u03b2. Furthermore, HA/GA-NPs-MNs enhanced drug accumulation and skin penetration, enabling efficient delivery into the deeper skin layers. During in vivo studies, the system was observed to significantly enhance immune regulation and demonstrated the strongest efficacy in suppressing psoriatic inflammatory infiltration. The primary therapeutic mechanism of HA/GA-NPs-MNs against psoriasis involved the blockade of STAT3 phosphorylation to inhibit IL-23 signaling and downstream IL-17 release. The biosafety assessment confirmed high dermal and hemocompatibility of the system. This work presented a novel integrated platform of multifunctional self-assembled nanoparticles and immunomodulatory microneedles for the topical treatment of psoriasis.",

To overcome these limitations, we developed an all-in-one prodrug nanoplatform based on hyaluronic acid (HA) that synergistically integrates active targeting, pH-responsive charge reversal, and controlled drug release. Doxorubicin (DOX) was covalently conjugated to oxidized HA via a pH-sensitive imine bond, while a charge-reversal polymer (PLL-DMMA) was grafted onto the HA backbone. This design enables CD44-mediated active targeting toward cancer cells. Crucially, the nanoplatform exhibits a smart charge-reversal characteristic: maintaining a negative surface charge (-32.8\u00a0mV) at physiological condition (pH 7.4) for extended circulation, while switching to positive (+16.5\u00a0mV) in the acidic tumor microenvironment (pH 6.5) to enhance cellular uptake. In vitro studies demonstrated significantly improved internalization in CD44-overexpressing MKN-45 cells compared to SNU-216 cells with low CD44 expression. The release profile showed high stability at pH 7.4 (<5% release in 5\u00a0days) and rapid drug release at endo/lysosomal pH (61.6% at pH 5.0). Cytotoxicity assays confirmed enhanced efficacy of the charge-reversed formulation, with lower IC50 values in both cell lines. This multifunctional prodrug nanoplatform represents a promising strategy for precision cancer chemotherapy through synergistic enhancement of tumor targeting and intracellular drug delivery.",

A rare but potentially life-threatening cause of secondary PPH is uterine artery pseudoaneurysm (UAP). In this case report, we present two clinical cases of UAP and review the available literature summarizing clinical symptoms, diagnostic approaches, and treatment options. The first case involved a patient presenting with abdominal pain and syncope 6 days after vaginal delivery, subsequently diagnosed with a right-sided UAP and hemoperitoneum. The second patient presented with painless yet heavy vaginal bleeding and was also diagnosed with a right-sided UAP. Both patients were successfully managed with uterine artery embolization. UAP may present atypically, either with or without vaginal bleeding. Possible reported risk factors include cesarean delivery, uterine curettage, endometriosis, inflammation, cervical conization, myomectomy, and excision of cesarean scars. Transvaginal sonography is the first-line diagnostic tool due to its accessibility, while computed tomography (CT) or magnetic resonance imaging are helpful for confirmation and treatment planning. Endovascular embolization is the treatment of choice in hemodynamically stable patients due to its minimally invasive nature and favorable outcomes.",
"42328561": "ID: 42328561\nTitle: PBMC-derived FGF, PDGF, VEGF and GM-CSF secretion in endometriosis: a case-control in vitro study.\nAbstract: Endometriosis is a chronic inflammatory disease with immune dysregulation in which angiogenic, and hematopoietic mediators are thought to contribute to ectopic lesion establishment and persistence. Whether circulating immune cells are intrinsically primed to secrete higher levels of pro-angiogenic growth factors remains unclear. This study evaluated in vitro secretion of fibroblast growth factor (FGF), platelet-derived growth factor (PDGF), vascular endothelial growth factor (VEGF) and granulocyte-macrophage colony-stimulating factor (GM-CSF) by peripheral blood mononuclear cells (PBMCs) from women with and without endometriosis. In a case-control design, women with laparoscopically and histopathologically confirmed endometriosis (n\u202f=\u202f36) and laparoscopically confirmed controls without endometriosis (n\u202f=\u202f44) were enrolled. PBMCs were isolated from peripheral blood and cultured for 24\u202fh under basal conditions or after non-specific mitogenic activation with phytohemagglutinin (PHA, 5\u202f\u03bcg/mL). Supernatant concentrations of FGF, PDGF, VEGF and GM-CSF were quantified using a multiplex bead-based immunoassay (Bio-Plex/Luminex). Between-group comparisons used nonparametric tests; univariate logistic regression explored associations with endometriosis status; and false discovery rate (Benjamini-Hochberg) adjustment was applied for multiple testing. Baseline secretion of FGF, PDGF, VEGF and GM-CSF by PBMCs did not differ significantly between women with endometriosis and controls after correction for multiple comparisons. PHA stimulation induced marked shifts in secretion profiles across participants- characterized by increases in FGF, PDGF and VEGF and a decrease in GM-CSF-but neither stimulated concentrations nor percent changes differed significantly between groups following false discovery rate adjustment. In univariate logistic regression analyses, none of the baseline growth-factor measures significantly predicted the presence of endometriosis. Under standardized in vitro culture conditions, PBMCs from women with endometriosis do not show a generalized increase in secretory capacity for the evaluated pro-angiogenic/hematopoietic growth factors compared with PBMCs from controls without endometriosis. These data do not support systemic PBMC hypersecretion of FGF, PDGF, VEGF and GM-CSF in endometriosis and are consistent with a compartmentalized model in which disease-relevant pro-angiogenic signaling is predominantly shaped within local peritoneal and lesion microenvironments.",
"42346610": "ID: 42346610\nTitle: Epigenetics, Oxidative Stress, and the Microbiome in Endometriosis: Toward an Integrated Mechanistic Framework for Precision Medicine.\nAbstract: Endometriosis (EM) is a chronic, estrogen-dependent inflammatory disorder affecting approximately 6-10% of women of reproductive age in the general population and remains a major cause of chronic pelvic pain and infertility. High recurrence rates and enduring symptoms despite current treatments underscore the need for a more thorough understanding of its intricate biology. There is growing evidence that the interaction among oxidative stress (OS), microbiome dysbiosis, and epigenetic dysregulation contributes to immunological activation, hormonal imbalance, and the persistence of ectopic lesions. Important disease mechanisms, such as progesterone resistance, inflammatory signaling, and aberrant cellular proliferation, are influenced by epigenetic changes, which include aberrant DNA methylation, histone modifications, and dysregulated non-coding RNAs. Simultaneously, high levels of reactive oxygen species (ROS) reinforce lesion survival and chronic inflammation by promoting angiogenesis, fibrosis, and tissue damage. Changes in the microbiome also affect immunological responses, oxidative balance, estrogen metabolism, and epigenetic control, indicating the existence of interrelated pathogenic loops. This narrative review presents an integrated mechanistic framework for endometriosis, summarizing the available data that connect these pathways. Furthermore, the growing implications of non-invasive biomarkers and precision medicine techniques highlight the potential for improved diagnosis, disease classification, and targeted treatment approaches.",

In this study, we designed a hyaluronic acid-based prodrug system, HA-Ns-Dox, that integrates receptor-mediated cellular uptake with intracellular glutathione (GSH)-responsive activation. A doxorubicin (Dox) prodrug modified with a 2-nitrobenzenesulfonyl (Ns) group was synthesized and subsequently conjugated to hyaluronic acid (HA) via click chemistry to generate HA-Ns-Dox with both CD44-targeting capability and GSH-responsive activation properties. HA-Ns-Dox formed stable nanosized assemblies in aqueous solution and exhibited high stability under low-GSH conditions mimicking extracellular environments, whereas concentration-dependent activation of Dox was observed under high-GSH conditions mimicking intracellular reductive environments. In vitro studies demonstrated that HA-Ns-Dox was selectively internalized into the CD44-high human breast cancer cell line MDA-MB-231, accompanied by intracellular prodrug activation and nuclear accumulation of Dox. In contrast, cellular uptake and activation were minimal in the CD44-low cell line MCF-7, and cytotoxicity was significantly suppressed even at high concentrations. Cytotoxicity studies further revealed that HA-Ns-Dox exhibited significant antiproliferative activity in CD44-high cells while substantially reducing toxicity toward non-target cells. Collectively, these findings demonstrate the potential of combining CD44-targeted delivery with GSH-responsive prodrug activation to improve cancer cell selectivity.",
"42401307": "ID: 42401307\nTitle: Steroidal alkaloids as multi-target therapeutics for the treatment of endometriosis.\nAbstract: Endometriosis is a chronic inflammatory disease characterised by ectopic endometrial tissue, progressive fibrosis and chronic pain, with a pathogenesis that goes beyond oestrogen dependence. The central question this review seeks to answer is: are steroidal alkaloids - nitrogenous plant-derived steroids with a unique structure - a mechanistically sensible, non-hormonal alternative that can simultaneously target the inflammatory, fibrotic and epigenetic drivers of endometriotic lesion persistence, while preserving fertility and avoiding systemic hormonal suppression? A growing body of evidence points to non-hormonal molecular networks including immune dysregulation, angiogenesis, and resistance to apoptosis as drivers of lesion persistence. These molecular disturbances are associated with treatment resistance and limit the long-term efficacy of hormone-based therapies. This review synthesises recent mechanistic advances that describe the non-hormonal signalling pathways that maintain endometriotic lesions, with a specific emphasis on NF-\u03baB-mediated sterile inflammation, inflammasome activation, PI3K/Akt/mTOR-dependent survival signalling, Hedgehog-driven fibrosis and epigenetic repression of progesterone receptor expression. Steroidal alkaloids are critically reviewed as multitarget modulators suppressing inflammatory signalling, inhibiting invasive and fibrotic remodelling, and restoring apoptotic sensitivity in this pathophysiological context, without direct systemic oestrogen deprivation. Structural determinants of steroidal alkaloid activity, including glycosylation status, nitrogen topology and configuration of the steroidal scaffold, are discussed in the context of pathway selectivity, pharmacokinetics and toxicity. Preclinical in vitro and in vivo evidence is critically reviewed in the context of key translational limitations such as bioavailability constraints, narrow therapeutic index and teratogenic risk from developmental pathway inhibition. This review highlights steroidal alkaloids as a mechanistically rational, non-hormonal approach to target lesion persistence and fibrosis in endometriosis, integrating molecular, pharmacological and structural insights, and outlines the major hurdles that must be overcome for clinical translation. The main objective of this review is to address a specific unanswered question: can steroidal alkaloids with their multitarget pharmacology offer a biologically coherent, non-hormonal strategy for the treatment of endometriosis that goes beyond oestrogen deprivation to target the molecular machinery of lesion survival, fibrosis and immune dysregulation. This question is addressed by reviewing the nonhormonal signalling networks that support ectopic lesions, the structural and pharmacokinetic properties of steroidal alkaloids that are relevant to these pathways, and the translational challenges that need to be addressed for clinical translation.",

This study examined the effects of TSS on fecundity and endometriosis-like lesions during pregnancy in a murine model of endometriosis. Endometriosis model mice were divided into four groups: Sham operation\u202f+\u202fcontrol diet (Sham/Cont), Sham operation\u202f+\u202f3% TSS diet (Sham/TSS), Endometrium dispersion\u202f+\u202fcontrol diet (End/Cont), and Endometrium dispersion\u202f+\u202f3% TSS diet (End/TSS). Mating was initiated one day after surgery, and females were sacrificed on postpartum day 3. Endometriosis-like lesion size, inflammatory cytokine levels, and reproductive outcomes were evaluated. Time to delivery tended to be shorter in the End/TSS group than in the End/Cont group (median: 23.5 vs. 27 days), although the difference was not statistically significant. The maximum lesion diameter in the End/TSS group was significantly smaller compared to the End/Cont group (median: 4.54\u202fmm vs. 7.76\u202fmm, p\u202f=\u202f0.044). Concentrations of the inflammatory cytokines MIP-3\u03b1 and IL-17A were significantly lower in the End/TSS group (MIP-3\u03b1: 14.54 [12.91, 18.98] vs. 25.26 [16.81, 48.58] pg/mg protein, p\u202f=\u202f0.019, IL-17A: 10.00 [9.05, 18.76] vs. 19.06 [16.75, 82.81] pg/mg protein, p\u202f=\u202f0.019). TSS administration reduced endometriosis-like lesion size and was associated with suppression of Th17-related inflammatory mediators in a murine model of endometriosis. Consequently, the administration of TSS tended to shorten the time to pregnancy. These findings suggest that TSS may exert immunomodulatory effects within endometriosis lesions and could represent a potential non-hormonal therapeutic approach during the peri-conceptional period.",
"42421100": "ID: 42421100\nTitle: The endometriosis-adenomyosis spectrum: shared pathophysiology and microenvironment-driven disease divergence.\nAbstract: Endometriosis and adenomyosis are common gynecologic disorders associated with dysmenorrhea, chronic pelvic pain, and infertility. Although they share several molecular features, the mechanisms by which endometrium-derived tissues develop distinct pathological phenotypes in different tissue environments remain incompletely understood. This review summarizes shared and divergent pathogenic mechanisms, focusing on lesion-specific microenvironments. This narrative review was based on a PubMed literature search from the year of the first publication through December 2025 using terms related to endometriosis, adenomyosis, mitochondrial function, oxidative stress, fibrosis, mechanical stress, and calcium signaling. Both disorders develop in the context of repetitive tissue injury, estrogen-dependent repair responses, chronic inflammation, oxidative stress, and mitochondrial dysfunction. However, differences in lesion location and microenvironment appear to drive distinct pathological phenotypes. In superficial peritoneal endometriosis and ovarian endometrioma, mitochondrial adaptation primarily supports hypoxia tolerance, oxidative stress responses, angiogenesis, cellular survival, and metabolic reprogramming. In contrast, deep infiltrating endometriosis and adenomyosis are characterized by fibrosis, extracellular matrix remodeling, tissue stiffening, and adaptation to mechanical stress. In adenomyosis, mitochondrial regulation of calcium homeostasis, smooth muscle contractility, reactive oxygen species production, and TGF-\u03b2-related fibrotic signaling may play important roles in disease progression. We propose a proliferation-fibrosis divergence model in which common pathogenic stimuli are integrated through mitochondria-dependent responses to distinct local microenvironments. Mitochondria may act as central regulators linking hypoxic adaptation, inflammation, metabolism, fibrosis, and mechanotransduction, thereby influencing whether disease progression favors proliferative expansion or fibrotic remodeling. This framework may provide a basis for future mechanism-based precision therapeutic strategies.",
"42421776": "ID: 42421776\nTitle: Self-organizing three-dimensional dermal papilla cell spheroids yield therapeutic extracellular vesicles that target hypertrophic scar regression via the miR-26a-5p/CCNE2 axis.\nAbstract: Hypertrophic scarring remains a critical challenge in regenerative medicine because of the limited efficacy of current antifibrotic therapies. Although dermal papilla cells (DPCs) exhibit intrinsic scar-inhibitory potential, their therapeutic utility is constrained by rapid replicative senescence and poor scalability in traditional monolayer cultures, necessitating innovative strategies to enhance cellular functionality and manufacturing feasibility. A self-feeder layer 3D (SFL-3D) platform was established to reprogram primary human DPCs into rejuvenated three-dimensional DPC (tdDPC) spheroids via autocrine-paracrine signalling activation. tdDPC-derived extracellular vesicles (tdDPC-EVs) were isolated from culture supernatants by differential centrifugation. The antifibrotic effects of tdDPC-EVs were systematically evaluated using human scar fibroblasts through scratch wound healing assays, CCK-8 proliferation assays, and fibrotic marker analysis [Western blotting and immunofluorescence staining for \u03b1-smooth muscle actin (\u03b1-SMA) and collagen I]. Bioinformatics was used to predict key pathways involved in hypertrophic scar (HS) pathogenesis, whereas gain/loss-of-function studies investigated the miR-26a-5p/CCNE2 regulatory axis. Therapeutic validation was performed in a rabbit ear hypertrophic scar model with histopathological and molecular profiling. Compared with conventional 3D cultures, the SFL-3D system demonstrated superior proliferative support, enabling stable tdDPC expansion beyond 10 passages while maintaining high viability and enhanced EV biogenesis. miR-26a-5p-enriched tdDPC-EVs attenuated fibrosis through two mechanisms: (1) silencing CCNE2 to block PI3K/AKT-driven collagen overproduction and (2) suppressing \u03b1-SMA\u2009+\u2009myofibroblast differentiation. In the rabbit ear HS model, tdDPC-EV administration reduced the scar elevation index and restored the collagen I/III ratio to near-physiological levels. This study positions tdDPC-EVs as a scalable acellular therapy that overcomes the replicative senescence and manufacturing limitations of cellular approaches. The antiscarring efficacy of these EVs, which is mediated by the miR-26a-5p/CCNE2/PI3K/AKT axis, highlights their clinical potential as precision-targeted strategies for hypertrophic scar management. The SFL-3D platform further provides a translatable framework for EV-based regenerative therapeutics.",

Vehicles that carry these signals and mediate this crosstalk are unknown. We hypothesize that extracellular vesicles (EVs) released post-MI mediate splenic immune trafficking to the heart. Mice were treated daily with an EV biogenesis inhibitor (GW4869) or vehicle. Splenic/cardiac immune cells were assessed at 3d while survival, cardiac function, hypertrophy, and fibrosis were evaluated at 8w post-MI. Plasma EVs from 1d MI mice or from the hearts that underwent MI/sham in a Langendorff system induced splenic immune trafficking to the heart within 3d and systolic dysfunction at 8w in na\u00efve mice. GW4869 i) inhibited splenic regression, ii) increased splenic retention of neutrophils, monocytes, dendritic cells (DCs), and CD4+ T-cells, iii) decreased cardiac gene expression of proinflammatory cytokines/chemokines, and iv) decreased trafficking of immune cells to the hearts at 3d post-MI, and iii) improved systolic function and attenuated hypertrophy at 8w post-MI. MI EVs accumulated in the spleen and promoted egress of matured splenic immune cells upon administration to na\u00efve mice. Cardiac pro-inflammatory cytokines/chemokines expression and CCR2+MHC-IIhi infiltrating macrophages, CD11c+ DCs, and CD4+ and CD4+TNF\u03b1+ T-cell levels were also increased in na\u00efve mice at 3d post-injection. Importantly, transfer of MI EVs for 2 days induced systolic dysfunction, cellular hypertrophy, and fibrosis in na\u00efve mice at 8 w post-injection. DCs process MI EVs for T-cells activation. EVs mobilize splenic immune cells to the heart post-MI and their inhibition can subdue inflammatory tissue-damage to promote healing post-MI.",

The field is scientifically attractive because cancer cells and tumor-associated stromal cells remodel their glycocalyx, overexpress selected carbohydrate-recognizing receptors and display altered metabolic demand; however, the translation of glycoengineered nanomedicine remains limited by low tumor delivery efficiency, heterogeneous receptor density, competitive off-target uptake by liver and macrophages, batch-to-batch variation in ligand density and insufficient quantitative reporting. This review re-frames carbohydrate-mediated cancer drug delivery as an evidence-weighted design problem. It integrates receptor-density data, particle-size boundaries, ligand-density ranges, release-rate targets, in vitro uptake metrics, pharmacokinetic endpoints and preclinical efficacy readouts into a quantitative framework. Special attention is given to hyaluronic acid-CD44, galactose/GalNAc-ASGPR, mannose-CD206, sialylated glycan-siglec/selectin, beta-galactoside-galectin and glucose/GLUT-related approaches, with emphasis on what the available data can and cannot prove. The central conclusion is that molecular glycoengineering is most defensible when carbohydrate chemistry is linked to measurable receptor engagement, competitive inhibition, uptake kinetics, intracellular drug exposure and statistically stronger antitumor benefit rather than to generic claims of active targeting. The framework explicitly links anomeric configuration, glycosidic linkage, branching, sulfation/acetylation, epitope display and glycan-protein hydration to receptor-specific pharmacological outcomes, thereby shifting the emphasis from general nanomedicine performance to carbohydrate structure-activity relationships required for a carbohydrate-chemistry readership.",

While maternal body mass index (BMI) influences pregnancy outcomes, its associations with RP are unclear. We aimed to examine associations between BMI, demographic and clinical factors, and RP using a nationally representative inpatient dataset. This retrospective study analyzed data of women aged \u226518\u2009years with delivery hospitalizations from the US Nationwide Inpatient Sample 2016-2020. RP was identified using the ICD-10 codes. Included women were classified on the basis of BMI as non-obese (<30.0\u2009kg/m2), obese (30.0-39.9\u2009kg/m2), and morbidly obese (\u226540.0\u2009kg/m2). Weighted logistic regression analysis determined associations between study variables and RP occurrence. Among 3\u2009590\u2009940 delivery hospitalizations, 28\u2009935 women (0.8%) had RP. Multivariable analysis identified advanced maternal age (adjusted odds ratio [aOR]\u2009=\u20091.046, 95% CI: 1.044-1.049), obesity (aOR\u2009=\u20091.18), morbid obesity (aOR\u2009=\u20091.25), polycystic ovary syndrome (PCOS) (aOR\u2009=\u20091.33), endometriosis (aOR\u2009=\u20092.28), smoking (aOR\u2009=\u20091.33), multiple pregnancy (aOR\u2009=\u20092.37), uterine surgery (aOR\u2009=\u20092.04), abortion (aOR\u2009=\u20091.43), and infertility (aOR\u2009=\u20091.87) as independent risk factors for RP. Cesarean delivery (vs. vaginal delivery) was significantly associated with a lower risk of RP (aOR\u2009=\u20090.14). Subgroup analyses confirmed consistent risk factors across age, prematurity, and PPROM, with multiple pregnancy, endometriosis, PCOS, obesity, and smoking remaining significant predictors. Obesity is an independent risk factor for RP, and morbid obesity confers the highest risk. Study findings emphasize the need for patient-focused obstetric management in high-risk populations.",

Here, we developed a hyaluronic acid (HA)-coated MEL-based polymersome (PMHA) for CD44-targeted codelivery of MEL and celecoxib (CXB). MEL was incorporated into the vesicular membrane, whereas CXB was loaded into the hydrophobic domain. PMHA showed a hydrodynamic diameter of 265.5\u2009\u00b1\u20091.6\u2009nm, a zeta-potential of -21.14\u2009\u00b1\u20091.1\u2009mV, a CXB encapsulation efficiency of 70.81\u2009\u00b1\u20094.18%, and a drug loading capacity of 12.87\u2009\u00b1\u20091.92%. In lipopolysaccharide (LPS)-stimulated RAW 264.7 macrophages, anti-CD44 antibody blocking reduced Alexa Fluor 647-labeled PMHA uptake by approximately 37.5%, supporting HA-CD44-mediated internalization. PMHA reduced MEL-associated cytotoxicity and hemolytic activity and enabled pH-responsive CXB release. Codelivery of MEL and CXB suppressed cyclooxygenase-2\u2009(COX-2) and tumor necrosis factor-\u03b1 (TNF-\u03b1) expression, with combination index (CI) values of 0.48 and 0.67, respectively.

Kidney diseases represent a major global health burden, often progressing to chronic complications due to the limited efficacy and poor selectivity of conventional therapies, which are frequently associated with systemic toxicity. Accordingly, the development of targeted drug delivery systems is essential to improve therapeutic outcomes. In this study, advanced quatsomes were developed as a kidney-targeted nanosystem to enhance the delivery of curcumin, a natural polyphenolic compound with potent antioxidant and nephroprotective properties. The system was composed of di-dodecyl-dimethyl-ammonium bromide (DDAB), cholesterol, limonene, hyaluronic acid (HA) and surfactants, and was fabricated using the ethanol injection method. A 23 factorial design was employed to optimize formulation variables, including DDAB:cholesterol ratio, limonene:drug ratio, and surfactant concentration. The optimized formulation (desirability = 0.950) exhibited high entrapment efficiency (87.80%), nanosized vesicles (120.55\u00a0nm), and a positive surface charge (+38.30\u00a0mV). Transmission electron microscopy confirmed spherical morphology, while in-vitro release studies demonstrated a biphasic profile. The formulation also showed good physicochemical stability and enhanced antioxidant activity. Mechanistically, passive targeting via nanoscale size and cationic charge facilitated interaction with the glomerular filtration barrier and mesangial uptake, while limonene improved vesicle deformability. HA functionalization further enabled CD44-mediated active targeting. In vivo, the optimized system significantly reduced serum creatinine and blood urea nitrogen levels in a cisplatin-induced nephrotoxicity model, with histological evidence of renal protection. Overall, the developed quatsomes demonstrate promising potential as an efficient renal-targeted nanocarrier.",

A targeted drug delivery system (HLC) was constructed using hyaluronic acid (HA) nanomicelles co-loaded with lactate oxidase (LOX) and copper-doped carbon dots (CuCDs). Combined with \u03b1-PD-L1, a synergistic antitumor strategy integrating lactate metabolic regulation, cuproptosis, and immune activation was established. HLC achieves targeted accumulation through specific binding between HA and CD44 receptors on tumor cells. It directionally releases LOX and CuCDs in the acidic TME via pH-responsive properties. LOX efficiently clears lactate and elevates pH, blocking the HIF-1\u03b1/PD-L1 pathway to reverse immunosuppression. It also generates H2O2 in situ to provide substrates for Cu-mediated Fenton-like reactions, enhancing cuproptosis. In vitro experiments confirm that HLC promotes dendritic cell maturation and drives M2-type macrophage polarization toward the M1 phenotype. In vivo studies using CT26 tumor-bearing mouse models show that HLC combined with 808\u202fnm laser and \u03b1-PD-L1 significantly inhibits primary and distant tumor growth. It remodels the antitumor immune microenvironment with favorable biosafety.

This review examines studies published from 2019 to 2026, with emphasis on high-quality research in leading journals, and connects the structural parameters of HA with quantitative drug delivery efficiency and therapeutic performance. The major HA-based carrier systems, including micelles, liposomes, polymeric nanoparticles, metal-organic frameworks, and electrospun fiber systems, are critically analyzed in relation to HA molecular weight, degree of substitution, and ligand density, as well as their effects on hydrodynamic size, zeta potential, colloidal stability, and cellular uptake. Across these studies, the most effective designs generally feature nanoscale dimensions that balance circulation and tumor penetration while maintaining near-neutral or slightly negative surface potentials to minimize nonspecific interactions, highlighting the importance of rational physicochemical design for improving therapeutic performance.
Quantitative models of drug release, together with in vitro potency indices such as half-maximal inhibitory concentration (IC50) and combination index, as well as in vivo pharmacokinetic and efficacy indicators including half-life, area under the curve (AUC), and tumor-to-organ ratio, demonstrate how the configuration of HA influences therapeutic selectivity and systemic safety. To improve the rigor and reproducibility of future studies, this review further proposes a concise reporting framework integrating materials characterization, biological evaluation, and animal experiments, while highlighting the current limitations in standardization and cross-study comparability.
In conclusion, this review summarizes the current design principles of HA-based nanocarriers while critically discussing the remaining challenges, including CD44 heterogeneity, microenvironmental competition, and the lack of standardized evaluation strategies. Together, these perspectives provide practical guidance for the rational design, comparative evaluation, and clinical translation of next-generation HA-based nanocarriers.

To overcome the limitations of monotherapies, this study developed a multifunctional targeted nanoplatform (RLHMnH). This system consists of a hyaluronic acid (HA)-modified hollow manganese dioxide (H-MnO2) nanocarrier co-loaded with the anti-angiogenic drug Regorafenib (Reg) and the nitric oxide precursor L-Arginine (L-Arg) for synergistic triple therapy against CRC. The platform leverages HA-mediated CD44 receptor targeting to achieve enhanced tumor accumulation. Within the TME, the H-MnO2 framework undergoes rapid responsive decomposition. On one hand, Within the acidic and GSH-rich TME, H-MnO2 undergoes reductive degradation to release Mn2+, concomitantly depleting GSH and disrupting redox homeostasis. The released Mn2+ further catalyzes Fenton-like conversion of endogenous H2O2 into highly cytotoxic \u00b7OH, thereby inducing oxidative damage and tumor cell apoptosis. On the other hand, the concomitantly released Reg effectively blocks tumor angiogenesis by inhibiting the VEGFR2 signaling pathway, while L-Arg generates nitric oxide, synergistically reversing drug resistance, alleviating hypoxia, and activating anti-tumor immunity. Both in vitro and in vivo experiments demonstrated that RLHMnH, through integrating the triple synergistic mechanisms of CDT, anti-angiogenesis, and gas therapy, achieved a remarkable tumor inhibition rate of \u223c75% in a CT26 xenograft model and potently suppressed CT26\u202fcell viability to below 20% at 72\u202fh, showcasing significant suppression of CRC.

Physicochemical properties, drug release profiles, cellular uptake, anti-inflammatory activity, macrophage polarization, and anticancer activity were systematically evaluated in vitro. In vivo biodistribution and therapeutic efficacy were assessed in UC, CAC, and colon cancer mouse models, with anti-PD-L1 combination therapy in the colon cancer setting. HA@Cel/NPs exhibited uniform size (76.87 \u00b1 2.65 nm, PDI 0.166 \u00b1 0.012), stayed stable for 14 days, and achieved ~71% Cel release under high H2O2/\u03b1-amylase conditions within 8\u00a0h. The nanocarriers enhanced cellular uptake and promoted M1-to-M2 macrophage polarization in inflamed macrophages, while inducing potent CT26 cell apoptosis. Orally administered HA@Cel/NPs alleviated UC severity and suppressed CAC progression, with significantly reduced tumor burden. In colon cancer, intravenous HA@Cel/NPs combined with intraperitoneal anti-PD-L1 significantly boosted CD8\u207a and CD4\u207a T cell infiltration and effectively eradicated established tumors compared with HA@Cel/NPs monotherapy. HA@Cel/NPs offer a versatile, dual-route platform that bridges inflammation management and cancer immunotherapy, distinguishing itself from single-mechanism or single-disease nanocarriers.",
"42610136": "ID: 42610136\nTitle: Hyaluronic acid-coated niosomal sorafenib targets CD44 and suppresses NF\u03baB signalling in oral squamous cell carcinoma.\nAbstract: Oral squamous cell carcinoma (OSCC) remains highly lethal and is driven, in part, by chronic NF-\u03baB-mediated inflammation. Sorafenib, a multikinase inhibitor of RAF/VEGFR/PDGFR, can suppress these pathways, but its clinical utility is limited by hydrophobicity, toxicity, and poor tumor penetration. We engineered hyaluronic acid-coated niosomes encapsulating sorafenib (SOR@Nio/HA) to enable CD44-targeted delivery to OSCC cells. SOR@Nio/HA displayed a mean hydrodynamic diameter of 177\u00b18 nm (PDI=0.23-0.26) and high encapsulation efficiency (86.34%), with pH-responsive release (45% at pH=5.5 and 30% at pH=7.4, in 24 hr). In CAL27 cells, SOR@Nio/HA significantly enhanced cytotoxicity versus free sorafenib, lowering IC50 from 11.8\u00b11.1 \u00b5M to 5.2\u00b10.9 \u00b5M (P<0.01), and increased Annexin V/PI-defined apoptosis relative to controls. qRT-PCR showed suppression of NF-\u03baB targets, with COX-2 and MMP-9 reduced to 0.35-fold and 0.32-fold of the control, respectively, alongside a pro-apoptotic shift in the BAX/BCL-2 axis. Collectively, these data indicate that SOR@Nio/HA improves intracellular delivery and potentiates sorafenib's antitumor activity by CD44-mediated uptake and inhibition of NF-\u03baB-driven inflammatory and invasive programs. HA-guided niosomal sorafenib warrants in vivo validation as a selective nanotherapeutic strategy for OSCC."
