Prior work has shown that lymphatics transport 10-250 nm nanoparticles from peripheral tissues to the lymph node. However, the surface chemistry required to maximize this transport is poorly understood. Here, we determined the effect of surface poly(ethylene glycol) (PEG) density and size on nanoparticle transport across lymphatic endothelial cells (LECs) by differentially PEGylated model polystyrene nanoparticles. Using an established in-vitro lymphatic transport model, we found PEGylation improved the transport of 100 and 40 nm nanoparticles across LECs 50-fold compared to the unmodified nanoparticles and that transport is maximized when the PEG is in a dense brush conformation or high grafting density (Rf/D\u00a0=\u00a04.9). We also determined that these trends are not size-dependent. PEGylating 40 nm nanoparticles improved transport efficiency across LECs 68-fold compared to unmodified nanoparticles. We also found that PEGylated 100 nm and 40 nm nanoparticles accumulate in lymph nodes within 4 h after intradermal injection, while unmodified nanoparticles accumulated minimally. Densely PEGylated nanoparticles traveled the furthest distance from the injection site and densely PEGylated 40 nm nanoparticles had maximum accumulation in the lymph nodes compared to low density PEGylated and unmodified nanoparticles. Finally, we determined that nanoparticles are transported via both paracellular and transcellular mechanisms, and that PEG conformation modulates the cellular transport mechanisms. Our results suggest that PEG conformation is crucial to maximize nanoparticle transport across LECs and into lymphatic vessels, making PEG density a crucial design. Optimizing PEG density on nanoparticle formulations has the potential to enhance immunotherapeutic and vaccine outcomes. STATEMENT OF SIGNIFICANCE: Lymphatic vessels are an emerging target for drug delivery both in the context of modulating immune responses and enhancing bioavailability by avoiding first pass hepatic metabolism after oral delivery. Lymphatic vessels are the natural conduits from peripheral tissues to the lymph nodes, where the adaptive immune response is shaped, and eventually to systemic circulation via the thoracic duct. Lymphatics can be targeted via nanoparticles, but the surface chemistry required to maximize nanoparticle transport by lymphatics vessels remains poorly understood. Here, we demonstrate that coating nanoparticles with hydrophilic polyethylene glycol (PEG) effectively enhances their transport across lymphatic endothelial cells in vitro and in vivo and that both paracellular and micropinocytosis mechanisms underly this transport. We found that dense PEG coatings maximize lymphatic transport of nanoparticles, thus providing new material design criteria for lymphatic targeted drug delivery."

"abstract_text": "ID: 37517544\nTitle: Logistics and distribution of small extracellular vesicles from the subcutaneous space to the lymphatic system.\nAbstract: Small extracellular vesicles (sEVs) are small, cell-derived particles with sizes of approximately 100\u00a0nm. Since these particles include cargos such as host cell-derived proteins, messenger RNAs, and micro RNAs, they serve as mediators of cell-cell communication. While the analysis of the pharmacokinetic of sEVs after the intravenous injection have been reported, the lymphatic transport of sEVs remains unclear. The objective of this study was to provide insights into the intra-lymphatic trafficking and distribution of sEVs when they are injected into an interstitial space both in normal skin tissue and in cancerous tissue. When sEVs were Subcutaneously administered into the tail base and the tumor tissue, they preferably accumulated in the lymph nodes (LNs), rather than in the liver and the spleen. The findings reported herein show that the lymphatic transport of sEVs was drastically changed in model mice, in which a surgical treatment was used to modify to allow the dominant lymphatic flow from the footpad directly to the axillary LN via the inguinal LN. Based on the results, we conclude that when sEVs are injected into the subcutis space, they are preferably delivered to the LN via the lymphatic system. Further, the extent of accumulation of sEVs in the LN after subcutaneous injection was reduced when they were preliminarily incubated with Proteinase K. These results suggest that the lymphatic drainage of sEVs in normal skin tissue is regulated by membrane proteins on their surface. This reduction, however, was not observed in the case of cancer tissue. This discrepancy can be attributed to the presence of highly permeable lymphatic vessels in the tumor tissue. Further, the major cell subtypes that captured sEVs in the LN were LN-resident medullary sinus macrophages. These collective findings indicate that the lymphatic drainage of sEVs are mediated by proteins and, that they may appear to contribute to the control of the function of immune-responsive cells in the LNs."

The development of targeted and biocompatible drug delivery systems is urgently needed to control pulmonary inflammatory cascades while minimizing systemic toxicity. Plant-derived extracellular vesicles offer a naturally safe and anti-inflammatory platform for therapeutic delivery. Ginsenoside Rb1 (GRb1), a major bioactive compound from ginseng, possesses potent anti-inflammatory and anti-apoptotic properties, whereas lemon-derived EVs (LEVs) exhibit intrinsic antioxidant and anti-inflammatory effects. Here, we engineered a multifunctional, biocompatible drug delivery platform, GRb1@LEVs-cRGD, in which ginsenoside Rb1 is incorporated into and fused with LEVs to form hybrid bio-nanovesicles, while the vesicle surface is functionalized with cyclic RGD (cRGD) peptides to target integrin \u03b1v\u03b23 highly expressed in inflamed pulmonary tissues, thereby enhancing site-specific delivery. In vitro and in vivo studies confirmed that GRb1@LEVs-cRGD effectively inhibited M1 macrophage polarization, suppressed inflammatory cascades, and preserved epithelial-endothelial integrity. Furthermore, exogenous cholesterol loading improved vesicle stability, maintained the pH gradient, and enhanced the loading efficiency of tigecycline and vancomycin by six-fold. In murine models of bacterial pneumonia induced by carbapenem-resistant Klebsiella pneumoniae and methicillin-resistant Staphylococcus aureus, antibiotic-loaded GRb1@LEVs-cRGD efficiently accumulated at infection sites and exhibited synergistic anti-inflammatory and bactericidal effects. Overall, this study demonstrates that GRb1@LEVs-cRGD is a safe, targeted, and multifunctional therapeutic platform with significant potential for ALI/ARDS treatment."

Here, we designed and synthesized a plant-derived ginger exosome-coated albumin nanoparticle drug delivery system (GEBSS) loaded with Shikonin (SHK) and STM2457 (a METTL3 inhibitor) and probes into the mechanism of antitumor. We prepared and characterized GEBSS nanoparticles and evaluated their in vitro cellular uptake and targeting capabilities. The in vitro antitumor efficacy was assessed by measuring cell viability, clonogenic formation, oxidative stress, mitochondrial function, and apoptosis markers; biosafety was confirmed via a hemolysis assay. Furthermore, the ability of GEBSS to induce ICD was validated through Western blotting, ATP detection, and immunofluorescence assays, while its role in epigenetic regulation was elucidated using Dot Blot, MeRIP-qPCR, and RNA stability experiments. Finally, the in vivo antitumor effect of GEBSS was verified by intravenous administration in a nude mouse subcutaneous tumor model. A subsequent characterization revealed that GEBSS exhibited a concentrated size distribution around 142\u00a0nm, were efficiently absorbed by colorectal cancer (CRC) cells, and demonstrated inhibitory effects on tumor cell proliferation. In vivo experiments demonstrated excellent tumor-targeting ability, anti-tumor efficacy, and biocompatibility of GEBSS. Mechanistically, GEBSS induced apoptosis and immunogenic cell death (ICD) in tumor cells. Moreover, at the epigenetic regulation level, GEBSS suppressed cell proliferation by reducing the m6A methylation levels of immune checkpoint genes PD-L1 and CD47. This study explored the feasibility of producing naturally derived nanocarriers and, for the first time, employed a combination of SHK and STM2457 for CRC treatment, offering novel strategies and insights for nanomedicine in CRC treatment."

Aluminum and lipid nanoparticles have been used for this purpose, but their accumulation or widespread circulation in the body can lead to adverse effects. In contrast, physical adjuvants, which use physical energy to transiently stress tissues, do not persist in exposed tissues or cause lasting adverse effects. Herein, we investigate the effects of intradermal injection of endotoxin-free ovalbumin (OVA) protein alone without additional adjuvants using a needle-free pyro-drive jet injector (PJI) on tumor vaccination efficacy. Intradermal injection of OVA protein alone using PJI significantly increased OVA-specific CD8+ T cell expansion in the lymph node, although lymph node swelling was much less than when aluminum hydroxide was used. The injection also induced OVA-specific killing activity and antibody production and showed strong CD8+ T cell-dependent prophylactic antitumor effects against transplanted E.G7-OVA tumors. In particular, intradermal injection of the fluorescent OVA protein significantly enhanced its uptake by XCR1+ dendritic cells, which have a strong ability to cross-present extracellular proteins in the skin and draining lymph nodes. In addition, the injection increased the expression of HMGB1, one of the potent danger signals whose expression has been reported to increase in response to shear stress. Thus, intradermal injection of OVA protein alone without any additional adjuvants using PJI induces potent CD8+ T cell-mediated antitumor immunity by enhancing its uptake into XCR1+ dendritic cells, which have a high cross-presentation capacity accompanied by an increased expression of shear stress-induced HMGB1."

Traditional vaccine platforms, such as live-attenuated or inactivated pathogens, although immunogenic, often present safety concerns. Conversely, subunit vaccines, despite being safer, generally exhibit poor immunogenicity due to inadequate delivery of antigens to professional antigen-presenting cells (APCs). To address this issue, the development of innovative delivery systems has become a pivotal strategy to overcome significant biological barriers, including extracellular antigen degradation, suboptimal lymph node targeting, and inefficient cross-presentation necessary for CD8+ T cell activation. This review systematically explores recent advancements in delivery technologies aimed at enhancing antigen presentation, encompassing rationally engineered nanocarriers and sophisticated biomimetic platforms. We first examine how nanoparticle properties like size, surface charge, and ligand density affect intracellular trafficking and the transition from MHC-II to MHC-I cross-presentation. Then, we explore bioinspired systems such as extracellular vesicles, virus-like particles, and cell-membrane-coated nanoparticles that utilize natural biological traits for enhanced targeting and immune modulation. Additionally, we review new physical delivery methods like microneedle arrays and in situ electroporation for direct, minimally invasive antigen delivery to dendritic cells. Lastly, we discuss the potential of these platforms in personalized cancer vaccines and combination immunotherapies. By combining insights from materials science, immunology, and bioengineering, these next-generation delivery tools could enhance antigen presentation and transform precision vaccination and immune intervention."

Their combined application may enhance early dermal repair following laser-induced skin injury. This study compares 3 commercially available plant derived extracellular vesicle formulations; Exoline, Glow, and Elysee, administered alone or with LLLT, in a rabbit ear wound model. Characterization of these preparations, including particle content and composition, was limited, and dosing was volume based. Two hundred forty adult male New Zealand White rabbits were randomly assigned to eight groups: untreated control, extracellular vesicle monotherapies, combination therapies with LLLT, and LLLT alone. Standardized full thickness laser-induced thermal skin defects (1\u2005\u00d7\u20051\u2009cm, 2\u2009mm depth) were created on the ventral ear surface. Extracellular vesicles were injected locally immediately after injury, and LLLT (650\u2009nm, 4.8 J/cm2, once weekly) was applied in addition to its application immediately after the procedure. Tissue samples were collected at baseline, day 7, and day 14. Collagen deposition and angiogenesis were quantified using Masson trichrome staining and CD31 immunohistochemistry, respectively. All extracellular vesicle treated groups showed significantly greater collagen deposition and microvascular density compared with controls. Combination therapy enhanced early regenerative responses compared with monotherapies. Differences among products may reflect formulation characteristics. Plant derived extracellular vesicle injections are associated with enhanced early dermal regeneration in laser-induced skin wounds, particularly when combined with LLLT. Differences among products may reflect formulation characteristics, and longer-term effects require further study."

Existing technologies available for NO therapy, however, provide poor bioactivity within lymphatic tissues. In this work, we address this technology gap with a NO encapsulation and delivery strategy leveraging the formation of S-nitrosothiols on lymphatic-targeting pluronic-stabilized, poly(propylene sulfide)-core nanoparticles (SNO-NP). We evaluated in vivo the lymphatic versus systemic delivery of NO resulting from intradermal administration of SNO-NP benchmarked against a commonly used, commercially available small molecule S-nitrosothiol NO donor, examined signs of toxicity systemically as well as localized to the site of injection, and investigated SNO effects on lymphatic transport and NP uptake by lymph node (LN)-resident cells. Donation of NO from SNO-NP, which scaled in proportion to the total administered dose, enhanced LN accumulation by two orders of magnitude without substantially reducing lymphatic transport of NP or the viability and extent of NP uptake by LN-resident cells. Additionally, NO delivery by SNO-NP was accompanied by low-to-negligible NO accumulation in systemic tissues with no apparent inflammation.

After intraperitoneal injection, the nanoparticle platform facilitated efficient entry of mRNA into various endogenous antigen-presenting cells, including lymph node stromal cells, and elicited robust T\u00a0cell responses within a wider network of lymphoid tissues compared with dendritic cells. Following intravenous injection, mRNA-electroporated dendritic cells and the nanoparticle platform localized primarily in lung and spleen, respectively. When administered locally via an intradermal route, both platforms resulted in mRNA expression at the injection site and in robust T\u00a0cell responses in draining lymph nodes. This study indicates that multiple epitopes, customizable for specific patient populations and encoded by mRNA, can be targeted to different lymphoid tissues based on delivery vehicle and route, and constitute the groundwork for future studies using mRNA to reprogram exogenous or endogenous APCs for immunotherapy."

Exosomes, nanoscale extracellular vesicles derived from mesenchymal stem cells and dermal papilla cells (DPCs), offer a promising regenerative alternative by modulating key hair-growth pathways. This systematic review evaluates the efficacy, mechanisms, and translational challenges of exosome-based therapies for hair restoration in AGA. A comprehensive search was conducted across Google Scholar, Embase, PubMed, Scopus, and Web of Science for studies published from 2019 to 2025. The search strategy prioritized AGA-related terminology, including androgenetic alopecia, male pattern hair loss, female pattern hair loss, baldness, exosomes, extracellular vesicles, and hair regrowth. Following duplicate removal, 39 studies meeting Population, Intervention, Comparison, Outcome, and Study design criteria were included for qualitative synthesis. Preclinical data demonstrate that exosomes promote hair regeneration through multiple synergistic mechanisms: activation of the Wnt/beta-catenin and Sonic Hedgehog pathways, suppression of transforming growth factor beta (TGF-beta)/SMAD3 signaling, delivery of anti-inflammatory cytokines (e.g., IL-10), and rejuvenation of senescent DPCs via microRNA cargo (e.g., miR-122-5p). Early clinical studies report improvements in hair density (8-20%) and shaft thickness; however, the evidence base remains limited by small sample sizes, retrospective designs, lack of control groups, and inconsistent outcome measures. Emerging delivery systems, such as thermoresponsive hydrogels and microneedle patches, show promise in enhancing follicular penetration but require further validation. Exosome therapy represents a multi-target regenerative approach for AGA with a favorable preliminary safety profile. However, widespread clinical adoption is hindered by critical gaps in manufacturing standardization, scalability, regulatory frameworks, and robust long-term efficacy data. Future research must prioritize large-scale randomized controlled trials with standardized endpoints and Good Manufacturing Practice (GMP)-compliant production protocols to validate these findings and establish exosomes as a mainstream therapeutic option for AGA."

Lipid nanoparticles (LNPs) are a standard delivery carrier. However, LNPs often accumulate in the liver and exhibit transient protein expression. These limitations can restrict their safety and immunogenic potential. Here, we developed a modular, peptide-based nanocomplex to overcome the current limitations. The system comprises three functional peptides: an RNA-binding peptide (RBP) for condensation, l-polyglutamic acid (PGA) for charge modulation, and an APC-targeting cell-penetrating peptide (A-CPP). This A-CPP features a newly discovered 7-mer immune cell-binding motif identified in this study. We optimized the physicochemical properties by systematically fine-tuning the ratios of these peptide modules. The optimized nanocomplex formed stable particles under 200\u202fnm. Unlike LNPs, which showed significant liver accumulation, the peptide-nanocomplexes remained localized at the injection site and effectively drained to the lymph nodes. Furthermore, the peptide-nanocomplex retained mRNA expression for up to 7 days in vivo, whereas LNP-mediated expression diminished within 48\u202fh. In mice immunized with SARS-CoV-2 spike mRNA, this prolonged antigen exposure elicited robust neutralizing antibody titers comparable to LNPs. Notably, the peptide-nanocomplex induced significantly higher CD8+ T cell responses than LNPs. Moreover, the peptide-nanocomplex demonstrated an excellent safety profile in vivo with no toxicity observed even after daily injections for two weeks at doses up to 200 times higher. This study establishes a data-driven fine-tuning strategy for peptide-based mRNA delivery. The resulting peptide-nanocomplex offers a safer, lymph node-targeted, and longer-lasting efficacy alternative to lipid-based carriers for next-generation vaccines."

However, the EXOs with mannose-conjugated PEG-DSPE (EXO-PEG-man) exhibit excellent intracellular uptake into the DCs and boost the immune response by the incorporation of adjuvant, monophosphoryl lipid A (MPLA) within the EXO. After an intradermal injection, a higher retention of EXO-PEG-man is observed in the lymph nodes, which could be used for the efficient delivery of immune stimulators and antigens to the lymph nodes in vivo."

Nanocrystals, nanosuspensions, lipid vesicles, polymeric nanoparticles, nanogels, extracellular vesicles, and lipid nanoparticles have been integrated with coated, dissolving, hollow, and hydrogel-forming microneedles for local and systemic delivery. Here, integrated colloid-loaded microneedles refer to systems in which colloidal carriers are coated onto, incorporated into, infused through, or reservoir-coupled with microneedle platforms, whereas solid microneedle pretreatment followed by topical colloid application is discussed only as a microneedle-assisted comparator. For integrated colloid-loaded microneedles, performance is not determined solely by microneedle geometry, insertion efficiency, or drug loading, but rather by whether the carrier survives conversion into a microneedle product and remains functionally relevant after hydration and release in skin. Existing reviews mainly emphasize microneedle materials, fabrication strategies, therapeutic applications, or smart devices, whereas the colloidal determinants of performance remain less integrated. Unlike application-centered or platform-centered reviews, this review focuses on the state transitions and functional persistence of colloidal carriers across fabrication, storage, insertion, hydration, redispersion, and dermal biointerfacial transport. We therefore reframe these products as formulation-device-biointerface systems, with emphasis on carrier integrity, matrix compatibility, redispersion, and post-insertion fate as determinants of therapeutic performance. To support mechanism-based evaluation, we further propose a study-level evidence hierarchy and practical analytical/QbD framework for assessing intact carrier delivery, redispersibility, bioactivity, and translational quality attributes. Issues related to biologic stability, sterilization, storage, manufacturing scalability, regulatory complexity, and critical quality attributes are also discussed within a quality-by-design framework."

In this study, a methacrylated gelatin (GelMA)-based microneedle system was developed for the efficient transdermal delivery of extracellular vesicles derived from Polygonatum kingianum (PkEVs) to prevent UVB-induced skin photoaging. The PkEVs exhibited a typical spherical morphology, with an average diameter of 168.2\u00a0\u00b1\u00a010.1\u00a0nm, and were successfully incorporated into a GelMA-based microneedle system (Pk@MN) for transdermal delivery. Pk@MN exhibited sufficient mechanical strength, with a breaking force of approximately 0.36\u00a0N per needle, and showed a rapid PkEV release profile, with approximately 90% of PkEVs released within 10\u00a0min. In vitro, Pk@MN effectively inhibited UVB-induced oxidative stress and cellular senescence in HaCaT cells, as indicated by reduced intracellular reactive oxygen species (ROS) levels and decreased senescence-associated \u03b2-galactosidase (SA-\u03b2-Gal) positive cells. Pk@MN also suppressed LPS-induced inflammatory responses in RAW264.7 cells. In vivo, pretreatment with Pk@MN markedly inhibited UVB-induced skin photoaging in mice, maintained skin elasticity by suppressing epidermal thickening, and promote dermal collagen deposition, with a 2.1-fold increase in collagen density compared with the Model group. Moreover, Pk@MN significantly suppressed the expression of the proinflammatory cytokine interleukin-6 (IL-6), approaching the level observed in the Control group. Transcriptome sequencing analysis further suggested that the protective effects of Pk@MN were associated with the regulation of pathways related to inflammation, oxidative stress, and tissue repair. This study highlights a GelMA-based microneedle platform for efficient transdermal delivery of plant-derived extracellular vesicles and provides a promising strategy for preventing UVB-induced skin photoaging."

To reduce the amount of contrast agents injected in patients while fully benefitting both modalities, dual-modality probes are required. This study was first aimed at developing a hybrid PET-MRI probe by labeling superparamagnetic iron oxide nanoparticles (SPIONs) with 64Cu using a fast and chelator-free conjugation method, and second, to demonstrate the ability of the agent to target sentinel lymph nodes (SLNs) in vivo using simultaneous PET-MRI imaging.

Herein, we developed an innovative nanoprobe based on well-defined core crosslinked star (CCS) polymers for non-invasive fluorescence imaging of SLN. A well-defined biodegradable CCS polymer comprising multiple polyethylene glycol (PEG) arms and carboxyl terminal groups (denoted as CCS-COOH) was synthesized successfully by reversible addition-fragmentation chain transfer polymerization with a disulfide-based crosslinker reagent. Besides, CCS-COOH was coupled by tert-butyl carbazate to produce the CCS derivative with neutral butoxycarbonyl (Boc) terminal groups (denoted as CCS-Boc). By the removal of Boc groups, another CCS derivative with positive primary amino terminal groups (denoted as CCS-NH2) was also yielded. These CCS polymers had similar particle size but different surface charge. For SLN fluorescence imaging, the CCS polymers labeled by CY7, a near-infrared probe, exhibited superior in vitro photo-stability to CY7 alone. After intradermal injection of the CY7-labeled CCS polymers in a mouse model, they could efficiently accumulate in the lymph node of the mouse. CY7-labeled CCS-COOH having negatively-charged surface displayed longer duration time and higher fluorescence intensity in the lymph node as compared to its counterparts with neutral or positive charge surface. In vitro and in vivo toxicity tests supported low cytotoxicity of these CCS polymers against cell lines and low systemic toxicity.

Here, we designed and synthesized a plant-derived ginger exosome-coated albumin nanoparticle drug delivery system (GEBSS) loaded with Shikonin (SHK) and STM2457 (a METTL3 inhibitor) and probes into the mechanism of antitumor. We prepared and characterized GEBSS nanoparticles and evaluated their in vitro cellular uptake and targeting capabilities. The in vitro antitumor efficacy was assessed by measuring cell viability, clonogenic formation, oxidative stress, mitochondrial function, and apoptosis markers; biosafety was confirmed via a hemolysis assay. Furthermore, the ability of GEBSS to induce ICD was validated through Western blotting, ATP detection, and immunofluorescence assays, while its role in epigenetic regulation was elucidated using Dot Blot, MeRIP-qPCR, and RNA stability experiments. Finally, the in vivo antitumor effect of GEBSS was verified by intravenous administration in a nude mouse subcutaneous tumor model. A subsequent characterization revealed that GEBSS exhibited a concentrated size distribution around 142\u00a0nm, were efficiently absorbed by colorectal cancer (CRC) cells, and demonstrated inhibitory effects on tumor cell proliferation. In vivo experiments demonstrated excellent tumor-targeting ability, anti-tumor efficacy, and biocompatibility of GEBSS. Mechanistically, GEBSS induced apoptosis and immunogenic cell death (ICD) in tumor cells. Moreover, at the epigenetic regulation level, GEBSS suppressed cell proliferation by reducing the m6A methylation levels of immune checkpoint genes PD-L1 and CD47. This study explored the feasibility of producing naturally derived nanocarriers and, for the first time, employed a combination of SHK and STM2457 for CRC treatment, offering novel strategies and insights for nanomedicine in CRC treatment."

It is the first organized immune-stromal site exposed to lymph-borne melanoma-derived extracellular vesicles (EVs), soluble mediators, proteins, lipids, and non-coding RNAs (ncRNAs) before and during metastatic seeding. Current evidence supports a model in which melanoma-derived EVs traffic through lymphatic vessels, enter draining nodes, interact with lymphatic endothelial cells, medullary macrophages, dendritic cells, and T cells, and remodel lymphovascular, stromal, and immune compartments. Key vesicle-associated mechanisms include NGFR/p75NTR-positive small extracellular vesicles (sEVs) that drive lymphangiogenesis and nodal metastasis, PD-L1-positive vesicles that suppress T-cell activation, CD36-linked pathways that reshape myeloid lipid metabolism, and uPAR-associated vesicles that promote endothelial and matrix remodeling. EV-associated miRNAs, lncRNAs, and circRNAs may further regulate fibroblast activation, macrophage behavior, MAPK/ERK signaling, PTEN-related stromal restraint, glycolysis, autophagy, and tumor-suppressive pathways. This review integrates clinical SLN biology, lymphatic vesicle trafficking, cargo-specific protein and ncRNA pathways, immune tolerance, stromal remodeling, multi-omic profiling, and therapeutic interception.

While metabolites within the metastatic niche are increasingly recognized as determinants of organotropic metastasis, the role of exosome-mediated metabolite transfer in tumor-lymphatic endothelial cell (LEC) crosstalk remains largely unexplored. Here, we demonstrate that oleic acid (OA) is significantly enriched in both CC lymph node metastases and the peritumoral lymphatic microenvironment. Exosomes derived from highly metastatic CC cells actively package OA in a manner dependent on stearoyl-CoA desaturase (SCD), the rate-limiting enzyme of de novo fatty acid synthesis. Upon internalization by LECs, exosomal OA triggers the AKT/mTOR signaling axis, eliciting robust LEC proliferation and endothelial-to-mesenchymal transition (EndMT), thereby fostering lymphangiogenesis and nodal colonization. Knockdown of SCD abolishes these pro-lymphangiogenic effects, a deficit fully reversed by the reconstitution of OA-loaded exosomes. In vivo, exosomes from SCD-silenced cells exhibit a severely compromised capacity to drive primary tumor growth, intratumoral lymphangiogenesis, and lymph node metastasis (LNM). Notably, free OA administration exerts substantially weaker effects than its exosomal counterpart, underscoring the superior efficiency of exosome-mediated metabolite trafficking. Clinically, FASN and SCD expression are significantly upregulated in lymph node-positive specimens and positively correlate with lymphatic vessel density and p-AKT levels. Furthermore, circulating exosomal OA levels are significantly elevated in patients with nodal involvement, suggesting its potential as a non-invasive diagnostic biomarker. Collectively, our findings establish a paradigm wherein tumor-derived exosomes function as specialized vehicles for intercellular OA transfer, activating the AKT/mTOR pathway to license lymphangiogenic reprogramming. This work identifies exosomal metabolite shuttling as a central node in tumor-lymphatic communication and proposes targeting OA synthesis or exosomal delivery as a promising therapeutic strategy against CC metastasis."

BC-derived exosomes influence intercellular communication within the tumor microenvironment, driving metastatic progression. However, the precise mechanisms by which exosomes facilitate LN metastasis in BC remain unclear. We performed small RNA sequencing on serum exosomes to identify Piwi-interacting RNAs (piRNAs) associated with BC LN metastasis. Functional investigations of exosomal piR-hsa-28212 included in\u00a0vitro assays for migration and tube formation of human lymphatic endothelial cells (HLECs), alongside an in\u00a0vivo footpad-popliteal LN metastasis model. Specific interactions between piR-hsa-28212 and TBX1 (T-box transcription factor 1), as well as TBX1 and VEGF receptor 3 (VEGFR3), were validated through luciferase reporter assays. The stability of TBX1 mRNA was analyzed by actinomycin D assay. RNA pulldown, RNA immunoprecipitation (RIP), and RNA fluorescence in\u00a0situ hybridization (FISH) assays were conducted to explore the interaction between piR-hsa-28212 and METTL3. PiR-hsa-28212 was significantly upregulated in serum exosomes of BC patients with LN metastasis.

Mechanistically, exosomal piR-hsa-28212 transferred from BC cells to HLECs stabilized TBX1 mRNA, thereby upregulating VEGFR3 expression. In BC cells, piR-hsa-28212 directly bound to and stabilized METTL3 protein, modulating N6-methyladenosine (m6A) methylation of vascular endothelial growth factor C (VEGFC) mRNA and consequently increasing VEGFC expression and secretion. Collectively, these findings reveal an exosome-mediated piRNA regulatory mechanism that synergistically amplifies VEGFC/VEGFR3 signaling to drive LN metastasis in BC, highlighting piR-hsa-28212 as a potential therapeutic target.

Knockdown of YBX1 in BCa cells suppressed lymphangiogenesis in vitro and in vivo and reduced M2 macrophage polarization. CXCL8 levels, elevated in BCa patients, were positively correlated with YBX1 and M2 macrophage infiltration, and this elevation was reduced upon YBX1 knockdown.

Extracellular matrix (ECM) remodeling aways accompany with chemotherapy, but its role in chemotherapy-associated metastasis is still unclear. Here, we reveal hyaluronidase-driven degradation of hyaluronic acid (HA) as a key mechanism underlying chemotherapy-associated lymphatic metastasis in gastric cancer. We found that chemotherapy-associated lymphatic metastasis of gastric cancer occurred during neoadjuvant chemotherapy in both patients and nude mice. The proportion of HA increased significantly in ECM during chemotherapy. We also found that cell migration inducing hyaluronidase 2 (CEMIP2) is the most highly expressed hyaluronidase to degrade HA into its effective type, low molecular weight HA (LMWHA), and promoted chemotherapy-associated lymphatic metastasis of gastric cancer. Mechanistically, CEMIP2-generated LMWHA activates CD44-ATF3 signaling to transcriptionally upregulate TGF\u03b2 receptor TGFBR1, driving metastasis. CEMIP2 is highly expressed in gastric epithelium naturally. To specifically target CEMIP2 and inhibit chemotherapy-associated lymphatic metastasis of gastric cancer, we developed bioengineered RGD-conjugated exosomes mimics (EMs) for targeted delivery of CEMIP2 siRNA. This strategy potently suppressed chemotherapy-associated lymphatic metastasis in vivo.

In this study, we developed a universal detection platform based on a G-quadruplex@DNA nano-highway network (G4@DNA-NHWN). This platform used aptamer-triggered hybridization chain reaction and streptavidin-biotin crosslinking to construct a protein-scaffolded DNA nanostructure enriched with split G4 via a one-pot method at room temperature, enabling sensitive and rapid detection of exosomes. Vimentin, a protein overexpressed in exosomes during the progression and metastasis of breast cancer, was selected as an example. Vimentin binding to the aptamer in G4@DNA-NHWN induces structural disassembly, preventing the split G4 from forming G4-Pb2+ complexes with Pb2+, thereby increasing the free Pb2+. Electrochemical (EC) detection enabled the homogeneous quantification of vimentin by directly distinguishing the EC signal differences between the inert G4-Pb2+ complex and Pb2+. The results demonstrated that this system achieved exosomes detection with a sensitivity as 30 particles/mL within 1 h, and exhibited excellent selectivity.

Lymphatic small extracellular vesicles (sEVs) derived from melanoma play a crucial role in establishing a premetastatic niche (PMN) within the sentinel lymph node (SLN). Therefore, analyzing the proteomic content of tumor-draining lymphatic sEVs that deliver oncogenic signals to the SLN is vital in understanding the PMN. To investigate this, we performed multiplexing (18 samples) using tandem mass tag labeling to profile the lymphatic sEV proteomes obtained from afferent lymphatic channels leading to the SLN of melanoma patients (n = 6), non-cancer-associated afferent lymphatic channels (n = 3), and postoperative lymphatic fluid after LN dissection (n = 9). We identified 595 new proteomic cargoes compared with those reported in ExoCarta and 1003 new cargo proteins relative to three previously reported lymphatic EV datasets. The analysis revealed 145 differentially expressed proteins of melanoma sEVs that link to increased cellular stress and injury pathways and a decrease in extracellular matrix organization (-log[p value] >7.0). Analysis of the top 50 differentially expressed proteins included expressions of normal, primary, and metastatic samples across multiple omics datasets. Hierarchical clustering with postoperative samples demonstrated nine upregulated and two downregulated proteins specific to melanoma sEVs, which are associated with melanoma progression (p < 0.05). Notably, several common proteins associated with melanoma and postoperative samples were related to the wound healing mechanism. The multiplex immunofluorescence analysis of selected proteins reveals significantly increased expression levels of CD38, galectin-9 (LGALS9), and tenascin-C (TNC) in the lymphatic sinuses of SLN (-) compared with the control LN sinuses. Moreover, higher levels of LGALS9 protein in LN tissue are associated with poor overall survival of melanoma patients (p = 0.0018). In summary, this study reveals an altered landscape of sEV proteome in the afferent lymphatic fluid of melanoma, highlighting distinct sEV proteins that are uniquely present in the SLN during PMN development."

Additionally, elevated levels of Prox1 were associated with shorter survival times. Correlation analysis demonstrated a significant relationship between Prox1 and markers associated with lymphangiogenesis, including LYVE1, FLT4, FOXC2, and ANGPT2. A clinical study involving 32 cases of CMM was conducted to analyze Prox1 expression and its relationship with lymphangiogenesis and clinicopathological characteristics. Research revealed that Prox1 was expressed significantly higher in patients with lymph node (LN) metastasis and in those classified as stage 3C-4. Additionally, the density of lymphatic vessels(LVD) in the LN metastasis group and the stage 3C-4 group was markedly higher than in the group without lymph node metastasis and in the stage 0-3B group. Furthermore, Breslow thickness was found to correlate with both Prox1 expression and LVD. Prox1-positive expression was associated with increased LVD. Further investigation was conducted on the role of Prox1 in the CMM cell line A375 and its derived exosomes. Exosomes were collected from CMMnc and CMMshProx1 to verify the changes in Prox1 expression, respectively. It was observed that the proliferation, migration, and tube formation abilities of human lymphatic endothelial cells(HLECs) diminished with the downregulation of Prox1.

This study analyzed MV-enriched EVs isolated from blood plasma of BC patients with negative (n\u2009=\u200919) and positive (n\u2009=\u200920) LNM (nLNM and pLNM, respectively) using differential centrifugation. Western blot analysis revealed significantly elevated SDC2 levels in MV-enriched EVs from pLNM cases compared to nLNM. Additionally, fibronectin (FN), a SDC2-interacting protein identified through STRING analysis, was also upregulated in pLNM MV-enriched EVs. In contrast, qRT-PCR showed reduced SDC2 (P\u2009<\u20090.01) and FN (P\u2009<\u20090.05) mRNA levels in tumor tissues of pLNM patients compared to nLNM. ROC analysis highlighted the diagnostic value of SDC2 (AUC: 0.8376) and FN (AUC: 0.8803) mRNA in differentiating LNM status. Bioinformatics analyses further confirmed the association of SDC2 and FN expression with BC staging and prognosis. These findings underscore the potential of circulating MV-enriched EV-associated SDC2 and FN, along with their tumor tissue mRNA expression, as potential predictive biomarkers for LNM and chemotherapy response in chemotherapy-na\u00efve obese BC patients."

In this study, we investigated a blood-based liquid biopsy assay of exosomal microRNA (miRNA) for the non-invasive detection of LNM in patients with high-risk EGC. Two genome-wide miRNA expression profiling datasets [GSE164174 and The Cancer Genome Atlas (TCGA)] were analyzed to prioritize biomarkers in pretreatment plasma samples from clinical training and validation cohorts of GC patients. An integrated exosomal miRNA panel was developed and a risk stratification model combining the miRNA panel with clinical risk factors was established. Using comprehensive expression profiling of public datasets, we identified a transcriptomic panel of four miRNAs (miR-34b, miR-130a, miR-375, and miR-627) that robustly identified patients with LNM [area under the curve (AUC) 0.86, 95% confidence interval (CI) 0.77-0.92]. We assessed panel performance in a training cohort (AUC 0.86, 95% CI 0.67-0.96) and validated it in an independent validation cohort (AUC 0.83, 95% CI 0.68-0.94). Our risk stratification model was more accurate than the panel and was an independent predictor of LNM identification (AUC 0.94). A novel, non-invasive, liquid biopsy-based method for patients with EGC may predict those conventionally classified as high-risk patients with LNM who are unlikely to benefit from surgical resection."

VEGF-C is a major lymphangiogenic ligand that plays a vital role in LN metastasis in PCa. However, in some PCa caseswith LN metastasis,VEGF-C is not upregulated, indicating that some VEGF-C-independent mechanisms are essential for lymphangiogenesis.Herein, we confirmed that extracellular vesicles (EVs) derived from PCa cells could promote LN metastasis in PCa independent of VEGF-C. We identified an EV circular RNA, circPDLIM5, that could promote lymphangiogenesis and lymphatic metastasis in both PCa cell lines and mouse models. Mechanistically, the packaging of circPDLIM5 into EVs was regulated by heterogeneous nuclear ribonucleoprotein A2B1. Subsequently, EVs were transmitted to human lymphatic endothelial cells, and EVs carrying circPDLIM5 could then directly interact with the transcription factor Yin Yang 1 to enhance the expression of Prospero homeobox 1, which is crucial for the formation, differentiation, and maturation of lymphatic vessels. Our findingshighlight the importance of a molecular mechanism mediated by EVs carrying circPDLIM5that is involved in lymphangiogenesis and LN metastasis in PCa; as a result, EVscarrying circPDLIM5 may be an attractive therapeutic target for LN-metastatic PCa."

Cancer associated fibroblasts (CAFs), major cell components in the TME, exert significant effects on malignant behaviors of various cancers. Triple negative breast cancer (TNBC) is the most malignant subtype of breast cancer with a high metastatic potential and poorer prognosis. However, the underlying mechanism by which CAFs promote TNBC development has not been sufficiently studied. The study aims to elucidate how CAFs promote TNBC aggressiveness by delivering protein-coding circMIB1 to activate MIB1/DLL4/Notch pathway, and provide a potential clinical biomarker for TNBC management. The oncogenic exosomal circMIB1 with protein-coding potential was identified through high-throughput RNA sequencing and ribosome nascent-chain complex sequencing (RNC-seq). The enrichment of circMIB1 in CAFs was confirmed using in situ hybridization (ISH) and qRT-PCR. The protein-coding capacity of circMIB1 was validated based on the polysome profiling, and luciferase assays. Functional roles of circMIB1 were explored using in vitro and in vivo models, while the underlying mechanism was dissected via co-immunoprecipitation (Co-IP) and western blotting. CAF-secreted exosomal circMIB1 promoted TNBC metastasis and stemness by translating a functional peptide, MIB1-223aa. Mechanistically, MIB1-223aa competitively bound to the E3 ubiquitin ligase RNF213, which blocked the RNF213-mediated K48-linked ubiquitination and degradation of MIB1. Moreover, the stabilized MIB1 enhanced the Notch signaling via a ubiquitination-dependent activation of the ligand DLL4, thereby driving TNBC malignancy. Clinically, high expression of circMIB1 or MIB1-223aa in TNBC tissues was correlated with poor clinical prognosis, as evidenced by reduced overall survival, shortened disease-free survival, and elevated lymphatic metastasis rates. This study provides the first evidence of exosome-transmitted protein-coding circRNAs in CAF-TNBC crosstalk, offering novel insights into the TME-driven metastasis and providing promising biomarker for TNBC management."

Using micromanipulator-assisted isolation of rare DCCs, single-cell mRNA and DNA sequencing, codetection by indexing immunofluorescence imaging and survival analysis, we identified melanoma-associated chondroitin sulfate proteoglycan (MCSP)+ melanoma cells as metastasis founder cells (MFCs). We found that DCCs entering SLNs predominantly exhibited a transitory phenotype that, upon interferon-\u03b3 exposure triggered by CD8 T cells, dedifferentiated into a neural-crest-like phenotype. This was accompanied by increased production of small extracellular vesicles (sEVs) carrying the immunomodulatory proteins CD155 and CD276 but rarely programmed cell death protein 1 ligand 1. The sEVs suppressed CD8 T cell proliferation and function, facilitating colony formation. Targeting MCSP+ MFCs or their immune escape mechanisms could be key to curing melanoma early by preventing manifestation of metastasis."

Many factors contribute to this dilemma, including lymphatic metastasis, which is the primary cause of PDAC metastasis. The inhibition of early lymph node metastasis, including the lymphangiogenic process, may be a novel strategy for PDAC treatment. Through miRNA sequencing of plasma extracellular vesicles (EVs) from PDAC patients, for the first time, we identified that plasma EV-miR-205-5p served as a non-invasive biomarker distinguishing lymphatic metastasis status (N0 vs. N2) in PDAC patients. Using tissue microarray and in situ hybridization, we discovered that miR-205-5p was highly expressed in PDAC, but negatively correlated with lymph node metastasis. By in vivo and in vitro experiments, we demonstrated its unique mechanism of action via EV-mediated transfer to human lymphatic endothelial cells (HLECs), leading to systematic downregulation of VEGFA and inhibition of the Akt/Erk pathway, which suppressed lymphangiogenesis.

Lymph node metastasis (LNM) of in cancer patients indicates poor prognosis and it is an important indication to determine the therapeutic regime. Therefore, more attention should be given to the molecular mechanics of tumor lymphangiogenesis and LNM. Extracellular vesicles (EVs) are nanoscale cargo-bearing membrane vesicles that can serve as key mediators for the intercellular communication. Like Hermes, the messenger of the Greek gods, EVs can be secreted by tumor cells to regulate the LNM process. Many evidence has proved the clinical correlation between EVs and LNM in various cancer types. EVs plays an active role in the process of metastasis by expressing its connotative molecules, including proteins, nucleic acids, and metabolites. However, the clear role of EVs in the process of cancer LNM has not been thoroughly studied yet. In this review, we will summarize the clinical and mechanical findings of EVs regulating role on cancer LNM, and discuss the advanced modification of the research proposal. We propose the \"PUMP\" principle of EVs in LNM, including Preparation, Unleash, Migration, and Planting."

However, the immunosuppressive microenvironment of TDLNs propels the formation of pre-metastatic niche, in which the immunocytes are dysfunctional, and the high expression of programmed death-ligand 1 (PD-L1) on dendritic cells (DCs) restricts the activation of cytotoxic T lymphocytes. Herein, engineered exosomes (EmDEX@GA) are developed for locoregional immunomodulation of TDLNs. EmDEX@GA possess CC-chemokine receptor 7 (CCR7) -dependent LN homing capacity and over-expressed programmed cell death protein 1 (PD-1) for immune checkpoint blockade (ICB). The loaded stimulator of interferon genes (STING) agonist can reinforce anti-tumor immunity through STING pathway activation. In orthotopic breast cancer mouse model, local administration of EmDEX@GA remodels the immunosuppressive microenvironment of TDLNs and elicits potent anti-tumor immunity, resulting in the suppression of tumor as well as the reduction of lymph node metastasis and distant metastasis. Compared with systemic ICB, local immunotherapy with EmDEX@GA has better therapeutic efficacy on suppressing distant metastasis. Moreover, the study suggests that the occurrences of distant metastasis are associated with the immunosuppressive microenvironment rather than the metastasis in TDLNs, indicating that targeted immunomodulation of TDLNs is necessary."

However, their expression and clinical value in gastric cancer (GC) remain poorly understood. Serum EV RNA was extracted from four patients with GC and four healthy controls, followed by high-throughput RNA sequencing. LncRNAs were further validated in training and validation sets using quantitative real-time reverse transcription polymerase chain reaction. A total of 37,684 lncRNAs were obtained, and 10 lncRNAs were selected based on the criteria (P < 0.05 and |log2FoldChange| \u22651). Serum EV lncRNA RMRP, RPPH1, and linc-ROR were significantly higher in patients with GC than in those with chronic gastritis, atypical hyperplasia, or healthy control (all P < 0.05). Three lncRNAs were also significantly correlated with tumor diameter, lymphatic metastasis, distal metastasis, and TNM stage (all P < 0.05). The area under the curve (AUC) values for lncRNA RMRP, RPPH1, and linc-ROR were 0.727, 0.774, and 0.811, respectively.

The combination of these three lncRNAs with carcinoembryonic antigen (CEA) yielded an AUC of 0.909, with a sensitivity and specificity of 83.3% each. Furthermore, high EV linc-ROR and RMRP expression levels were associated with worse disease-free survival and overall survival (OS). Univariate and multivariate Cox regression analyses confirmed that linc-ROR was the only independent prognostic factor for GC. Finally, the lncRNA-miRNA-mRNA network showed that three lncRNAs were predicted to interact with 15 miRNAs and 69 mRNAs. In addition, lncRNA RMRP and linc-ROR were correlated with immune cell infiltration, including neutrophils, central memory CD4 T cells, macrophage, and natural kill T cells. EV lncRNAs are prospective biomarker and correlated with immune cell infiltration in GC. It provides a foundation for the development of serum EV-targeted novel biomarkers and immunotherapy targets of GC."

Toward that end, we engineered BIO-GEM, a hierarchically structured biomimetic lymph node (bLN) platform comprising genipin-crosslinked gelatin microspheres (GEM) encapsulating deformable albumin-hitchhiking nanoemulsions (BIO, generated with bovine albumin, imiquimod adjuvant, and OVA antigen). Compared to conventional microparticles used for immune cell recruitment, BIO-GEM forms antigen-rich depots that better recruit antigen-presenting cells (APCs) and T cells, creating an immunostimulatory niche for in situ T-cell priming. Collagenase-responsive degradation of GEM triggers sustained release of BIO, which targets LNs via the albumin-hitchhiking pathway. This spatiotemporal delivery strategy synergizes bLN-resident immune activation with LN-directed antigen trafficking, yielding high CD8+ T-cell infiltration at injection sites, dendritic cell maturation, and elicitation of antigen-specific cytotoxic T cells. In multiple B16 murine melanoma models, BIO-GEM significantly suppressed tumor growth and extended the survival of mice.

In this study, we developed a dual strategy for augmenting subunit-vaccine-induced immune responses by integrating self-adjuvanting gold nanoparticle (GNP)-antigen conjugates with implantable chitosan (CS) microneedles (MNs) to achieve sustained intradermal antigen exposure. Conjugation of a model antigen, namely, ovalbumin (OVA), onto the GNP surface (GNP-OVA) resulted in virus-mimicking multivalent antigen display, which substantially enhanced dendritic cell maturation, as evidenced by the upregulation of CD86 and major histocompatibility complex class II. This conjugation strategy also enabled the efficient codelivery of the antigen and carrier into the same antigen-presenting cells, thereby facilitating improved antigen presentation. Furthermore, compared with free OVA and a physical GNP/OVA mixture, conjugated GNP-OVA exhibited considerably longer lymph node retention, primarily because of its nanovaccine properties, which facilitate its preferential trafficking into lymphatic vessels and its subsequent accumulation in lymph nodes. Encapsulation of GNP-OVA into CS MNs (i.e., GNP-OVA MNs) resulted in reliable skin implantation, sustained intradermal antigen exposure, and local immune cell recruitment. Rat immunization studies revealed that GNP-OVA MNs induced balanced T helper 1 and T helper 2 responses and elicited considerably higher and more durable OVA-specific immunoglobulin G levels than did subcutaneous vaccination with GNP-OVA or OVA alone. These responses persisted for at least 16 weeks, highlighting the potential of the developed platform for prolonged subunit vaccine immunization. This dual-strategy platform, combining virus-mimicking GNP-based nanovaccines with immunostimulatory CS MNs, reduces reliance on external adjuvants and enhances the potency and durability of subunit vaccines. Its modular and patient-friendly design underscores its high potential for advancing the development of next-generation vaccines against emerging infectious diseases."

Like other infectious fungal diseases, it becomes even more severe when it affects immunosuppressed patients. This infection has a global distribution and is endemic in some regions of Brazil and it is an important zoonotic public health problem. The disease is caused by a complex of at least four pathogenic species, including Sporothrix brasiliensis. The immunological response against these species has not yet been completely elucidated.

Thus, this work aims to analyze the participation of EVs from na\u00efve dendritic cells and EVs from DCs previously primed with S. brasiliensis yeast and primed with EVs from the fungus in the immune response against experimental sporotrichosis in murine models. The groups that received EVs from DCs primed with S. brasiliensis or their EVs showed a significant decrease in fungal load compared to the negative control group.

It is worth highlighting that all prophylactic protocols modulated and minimized fungal growth compared to the control; that is, EVs contributed to the control of the infection and acted in favor of the host, demonstrating a protective character."

Some mice were given intradermal injections of gliadin in complete Freund's adjuvant (immunization) or of soluble gliadin or ovalbumin (ear challenge).

Spleen or lymph node cells were analyzed in proliferation and cytokine secretion assays or by flow cytometry, RNA sequencing, or real-time quantitative polymerase chain reaction.

In the delayed-type hypersensitivity (model 1), the HLA-DQ8 transgenic (model 2), and the gliadin memory T-cell enteropathy (model 3) models of celiac disease, intravenous injections of TIMP-GLIA significantly decreased gliadin-specific T-cell proliferation (in models 1 and 2), inflammatory cytokine secretion (in models 1, 2, and 3), circulating gliadin-specific IgG/IgG2c (in models 1 and 2), ear swelling (in model 1), gluten-dependent enteropathy (in model 3), and body weight loss (in model 3). In model 1, the effects were shown to be dose dependent. Splenocytes from HLA-DQ8 transgenic mice given TIMP-GLIA nanoparticles, but not control nanoparticles, had increased levels of FOXP3 and gene expression signatures associated with tolerance induction. In mice with gliadin sensitivity, injection of TIMP-GLIA nanoparticles induced unresponsiveness to gliadin and reduced markers of inflammation and enteropathy. This strategy might be developed for the treatment of celiac disease."

While current treatments either inhibit bone resorption or stimulate bone formation, their long-term use is associated with adverse effects, necessitating alternative therapeutic approaches. In this study, we explore the use of red ginseng-derived nanovesicles (RGNVs) as a biocompatible nanotherapeutic strategy for treating osteoporosis. The RGNVs were successfully isolated and characterized, revealing a lipid bilayer structure enriched in bioactive ginsenosides and functional proteins. In vitro, RGNVs enhanced osteoblast proliferation, differentiation, and mineralization while suppressing osteoclast differentiation and bone resorption by modulating the BMP-2/Smad and MAPK signaling pathways. In an ovariectomy-induced osteoporosis mouse model, oral administration of RGNVs significantly restored bone volume and mineral density, and biodistribution studies confirmed their preferential accumulation in the bone tissue. Systemic toxicity evaluation indicated no adverse effects, supporting the safety of RGNVs for therapeutic use. These findings suggest that RGNVs regulate bone remodeling through a dual mechanism, to stimulate bone formation and inhibit bone resorption, thereby offering a promising and well-tolerated approach for osteoporosis management."

Given the high mortality of patients with esophageal squamous cell carcinoma (ESCC) and limited early detection tools, we investigated a salivary exosome\u2011based Tri-signature for its diagnostic and prognostic potential. The salivary exosome\u2011based signature (ie, a chimeric RNA seG-NchiRNA, a tRNA fragment GlyGCC-5, and a novel sRESE RNA) was quantified by qRT-PCR in a multicenter observational study across two ESCC-endemic regions. Model development and validation were performed in the training (n = 359) and validation (n = 225) cohorts using logistic regression, survival analyses, and Shapley Additive exPlanations-based feature interpretation. The Tri-signature showed excellent diagnostic accuracy (training cohort: AUC, 0.987; validation cohort: AUC, 0.964) and robust prognostic value (training cohort: overall survival [OS] hazard ratio [HR], 5.52, progression-free survival [PFS] HR, 4.46; validation cohort: OS HR, 4.76, PFS HR, 2.79). In the high Combined Risk Score for Prognosis (CRSP) subgroup, patients with relatively lower CRSP derived significant benefit from adjuvant therapy (training cohort: OS HR, 0.54, PFS HR, 0.47; validation cohort: OS HR, 0.38, PFS HR = 0.32), whereas no such benefit was observed in low Tri-signature patients. The Tri-signature exhibited strong early diagnostic performance, distinguishing early-stage ESCC without lymph node metastasis from healthy controls (training cohort: AUC = 0.975; validation cohort: AUC = 0.950). Patients with early-stage ESCC and high CRSP had significantly worse outcomes (training cohort: OS HR, 5.09, RFS HR, 3.80; validation cohort: OS HR, 8.79, RFS HR, 4.55). The salivary exosome-based tri-RNA signature showed robust multicenter reproducibility and strong diagnostic, prognostic, and treatment response-predictive performance, supporting its translational potential as a noninvasive biomarker panel for ESCC management."

It is identified by thickening of the dermis, connective tissue affected by collagen accumulation, and vascular injuries that induce hypoxia. The present study aimed to determine whether extracellular vesicles (EVs) from adipose-derived stem cells (ADSCs) attenuated bleomycin-induced skin fibrosis and oxidative stress in scleroderma. ADSCs and their EVs were separated and a bleomycin-induced SSc mouse model was constructed. High-throughput sequencing was employed to study abnormal expression of circular RNAs in SSc skin tissues with or without ADSC-EV treatment. The regulatory mechanism and targets were studied using bioinformatics analysis, luciferase reporting analysis, angiogenic differentiation experiments, and RT-qPCR detection analysis. EVs from ADSCs were successfully isolated. The exosome treatment prevented dermal thickening and fibrosis in bleomycin-induced scleroderma. In addition, circ-Zfyve9 was demonstrated to have an important function in ADSC-EV-mediated skin tissue protection. GPX4 and miR-135 were shown to be downstream targets of circ-Zfyve9. Overexpressing miR-135 or downregulating GPX4 reversed the promotion effects of circ-Zfyve9 on angiopoiesis by increasing lipidosome ROS in EPCs under hypoxic conditions. Overexpressing miR-135 or downregulating GPX4 reversed the inhibition effect of circ-Zfyve9 on fibrosis in myofibroblasts under hypoxic conditions.

Previous studies have shown that extracellular vesicles (EVs) derived from mesenchymal stem cells (MSCs) and human hair outer root sheath cells (HHORSCs) can enhance hair follicle development, ameliorate androgenetic alopecia, and support the inductive capacity of dermal papilla cells. However, the regulatory effects of HHORSC-derived EVs (HHORSC-EVs) and human bone marrow mesenchymal stem cell-derived EVs (HBMMSCEVs) on HFSCs remain unclear. HFSCs were treated with HHORSC-EVs or HBMMSC-EVs for 10 days. The effects of EVs on HFSC proliferation, apoptosis, and differentiation were evaluated using a Cell Counting Kit8 assay, flow cytometry, and immunofluorescence staining, respectively. EVs from both HHORSCs and HBMMSCs did not enhance hair follicle growth by improving the proliferation of HFSCs, but rather by inhibiting apoptosis. In addition, HBMMSC-EVs further promoted HFSC stemness maintenance by upregulating K15 and CD34 expression. HFSCs may serve as a novel target for both HHORSC-EVs and HBMMSC-EVs, highlighting their therapeutic potential for hair loss disorders. This study offers new insights into developing EV-based therapies for hair loss disorders."

Current treatments remain inadequate, highlighting the need for novel, effective, and cell-free therapeutic strategies. Extracellular vesicle-enriched preparations derived from human endometrial mesenchymal stem cells (eMSC-EV-enriched preparations) may possess regenerative and anti-fibrotic potential, yet their roles in scar modulation and underlying mechanisms remain unclear. eMSCs were isolated from human endometrial biopsies and characterized via flow cytometry and differentiation assays. The eMSC-EV-enriched preparations were obtained from conditioned medium and verified by TEM, NTA, and Western blotting. Functional assays were conducted in NIH3T3 fibroblasts to assess proliferation, migration, and transwell invasion capacity. A full-thickness cutaneous wound model and a bleomycin-induced dermal fibrosis model were used in C57BL/6 mice to evaluate tissue repair and fibrosis attenuation. Histological and molecular analyses were performed to assess collagen deposition, fibrosis-associated markers, and related signaling pathways. The potential involvement of miR-125b-5p in Smad2-related signaling was explored. The eMSC-EV-enriched preparations displayed characteristic vesicular morphology and marker expression. Compared with BMMSC-EV-enriched preparations, eMSC-EV-enriched preparations more effectively reduced fibroblast proliferation and migration, with decreased transwell invasion capacity in vitro. In vivo, the eMSC-EV-enriched preparations enhanced wound closure, reduced collagen deposition, and were associated with improved collagen organization and an increased number of appendage-like structures. Expression of \u03b1-SMA and collagen I and III was reduced in tissues treated with the eMSC-EV-enriched preparations. Furthermore, the preparations were associated with increased miR-125b-5p levels and decreased Smad2/p-Smad2 expression, suggesting involvement of the miR-125b-5p/Smad2 axis. In the bleomycin model, the eMSC-EV-enriched preparations attenuated dermal thickening and collagen accumulation during fibrosis induction. Our findings indicate that eMSC-EV-enriched preparations improve repair quality and attenuate fibrosis development, potentially through modulation of fibroblast activity and involvement of the miR-125b-5p/Smad2 signaling pathway. These findings support further investigation of eMSC-EV-enriched preparations as a cell-free strategy for improving tissue remodeling in fibrotic skin conditions."

For instance, MSC-EXO promotes skin healing post-laser therapy and improves outcomes in severe COVID-19. Selecting an optimal cellular source is critical for the therapeutic development of MSC-EXO. It has been suggested that GMP-produced MSC-exosomes have slightly different molecular content. This study therefore aimed to compare adipose tissue-derived MSC-EXO (ASC-EXO) from three healthy donors, isolated and characterized under GMP conditions. Exosomes were analyzed by nano-tracking analysis (NTA), cryo-electron microscopy, tetraspanin profiling, and multi-omics (proteomics, lipidomics, small RNA sequencing), as well as bioinformatics. Functional assays quantified anti-inflammatory effects in RAW264.7 macrophages and collagen production by human dermal fibroblasts (HDF). In vivo efficacy of ASC-EXOs was evaluated in a house dust mite antigen-induced atopic dermatitis mouse model through histopathological evaluation of ear thickness and differential cell counting. No significant batch differences were observed in ASC-EXO yield or characteristics. Omics analyses revealed minor variations in protein, lipid, and small RNA cargo among the three batches, but GO-term bioinformatics indicated highly similar functional profiles. IL-6 suppression in RAW264.7 cells and cell proliferation and collagen production by HDF were similar among the ASC-EXO batches. CD73 enzymatic activity was consistent among batches. In vivo, the ASC-EXOs reduced skin thickness and eosinophilia in an atopic dermatitis model, with similar effects among the batches. In summary, ASC-EXOs from all batches demonstrated comparable anti-inflammatory and collagen-modulating effects in vitro, and similar inhibition of atopic dermatitis signs in vivo. We suggest that biological efficacy combined with bioinformatics analysis should guide MSC-EXO therapeutic quality control assays. These findings support the development of ASC-EXOs for clinical applications."

"abstract_text": "ID: 35381399\nTitle: Nanoparticles with dense poly(ethylene glycol) coatings with near neutral charge are maximally transported across lymphatics and to the lymph nodes.\nAbstract: Lymphatic vessels have recently been shown to effectively deliver immune modulatory therapies to the lymph nodes, which enhances their therapeutic efficacy. Prior work has shown that lymphatics transport 10-250 nm nanoparticles from peripheral tissues to the lymph node. However, the surface chemistry required to maximize this transport is poorly understood. Here, we determined the effect of surface poly(ethylene glycol) (PEG) density and size on nanoparticle transport across lymphatic endothelial cells (LECs) by differentially PEGylated model polystyrene nanoparticles. Using an established in-vitro lymphatic transport model, we found PEGylation improved the transport of 100 and 40 nm nanoparticles across LECs 50-fold compared to the unmodified nanoparticles and that transport is maximized when the PEG is in a dense brush conformation or high grafting density (Rf/D\u00a0=\u00a04.9). We also determined that these trends are not size-dependent. PEGylating 40 nm nanoparticles improved transport efficiency across LECs 68-fold compared to unmodified nanoparticles. We also found that PEGylated 100 nm and 40 nm nanoparticles accumulate in lymph nodes within 4 h after intradermal injection, while unmodified nanoparticles accumulated minimally. Densely PEGylated nanoparticles traveled the furthest distance from the injection site and densely PEGylated 40 nm nanoparticles had maximum accumulation in the lymph nodes compared to low density PEGylated and unmodified nanoparticles. Finally, we determined that nanoparticles are transported via both paracellular and transcellular mechanisms, and that PEG conformation modulates the cellular transport mechanisms. Our results suggest that PEG conformation is crucial to maximize nanoparticle transport across LECs and into lymphatic vessels, making PEG density a crucial design. Optimizing PEG density on nanoparticle formulations has the potential to enhance immunotherapeutic and vaccine outcomes. STATEMENT OF SIGNIFICANCE: Lymphatic vessels are an emerging target for drug delivery both in the context of modulating immune responses and enhancing bioavailability by avoiding first pass hepatic metabolism after oral delivery. Lymphatic vessels are the natural conduits from peripheral tissues to the lymph nodes, where the adaptive immune response is shaped, and eventually to systemic circulation via the thoracic duct. Lymphatics can be targeted via nanoparticles, but the surface chemistry required to maximize nanoparticle transport by lymphatics vessels remains poorly understood. Here, we demonstrate that coating nanoparticles with hydrophilic polyethylene glycol (PEG) effectively enhances their transport across lymphatic endothelial cells in vitro and in vivo and that both paracellular and micropinocytosis mechanisms underly this transport. We found that dense PEG coatings maximize lymphatic transport of nanoparticles, thus providing new material design criteria for lymphatic targeted drug delivery."

The development of targeted and biocompatible drug delivery systems is urgently needed to control pulmonary inflammatory cascades while minimizing systemic toxicity. Plant-derived extracellular vesicles offer a naturally safe and anti-inflammatory platform for therapeutic delivery. Ginsenoside Rb1 (GRb1), a major bioactive compound from ginseng, possesses potent anti-inflammatory and anti-apoptotic properties, whereas lemon-derived EVs (LEVs) exhibit intrinsic antioxidant and anti-inflammatory effects. Here, we engineered a multifunctional, biocompatible drug delivery platform, GRb1@LEVs-cRGD, in which ginsenoside Rb1 is incorporated into and fused with LEVs to form hybrid bio-nanovesicles, while the vesicle surface is functionalized with cyclic RGD (cRGD) peptides to target integrin \u03b1v\u03b23 highly expressed in inflamed pulmonary tissues, thereby enhancing site-specific delivery. In vitro and in vivo studies confirmed that GRb1@LEVs-cRGD effectively inhibited M1 macrophage polarization, suppressed inflammatory cascades, and preserved epithelial-endothelial integrity. Furthermore, exogenous cholesterol loading improved vesicle stability, maintained the pH gradient, and enhanced the loading efficiency of tigecycline and vancomycin by six-fold. In murine models of bacterial pneumonia induced by carbapenem-resistant Klebsiella pneumoniae and methicillin-resistant Staphylococcus aureus, antibiotic-loaded GRb1@LEVs-cRGD efficiently accumulated at infection sites and exhibited synergistic anti-inflammatory and bactericidal effects. Overall, this study demonstrates that GRb1@LEVs-cRGD is a safe, targeted, and multifunctional therapeutic platform with significant potential for ALI/ARDS treatment."

The surface of the EXOs is modified with polyethylene glycol (PEG) without particle aggregation (\u224850 nm) via the incorporation of 1,2-distearoyl-sn-glycero-3-phosphoethanolamine (DSPE) into the lipid layer of the EXO, compared to chemical conjugation by N-hydroxysuccinimide activated PEG (NHS-PEG). PEG modification onto the exosomal surface significantly decreases the non-specific cellular uptake of the EXOs into the DCs. However, the EXOs with mannose-conjugated PEG-DSPE (EXO-PEG-man) exhibit excellent intracellular uptake into the DCs and boost the immune response by the incorporation of adjuvant, monophosphoryl lipid A (MPLA) within the EXO. After an intradermal injection, a higher retention of EXO-PEG-man is observed in the lymph nodes, which could be used for the efficient delivery of immune stimulators and antigens to the lymph nodes in vivo."

Here, we designed and synthesized a plant-derived ginger exosome-coated albumin nanoparticle drug delivery system (GEBSS) loaded with Shikonin (SHK) and STM2457 (a METTL3 inhibitor) and probes into the mechanism of antitumor. We prepared and characterized GEBSS nanoparticles and evaluated their in vitro cellular uptake and targeting capabilities. The in vitro antitumor efficacy was assessed by measuring cell viability, clonogenic formation, oxidative stress, mitochondrial function, and apoptosis markers; biosafety was confirmed via a hemolysis assay. Furthermore, the ability of GEBSS to induce ICD was validated through Western blotting, ATP detection, and immunofluorescence assays, while its role in epigenetic regulation was elucidated using Dot Blot, MeRIP-qPCR, and RNA stability experiments. Finally, the in vivo antitumor effect of GEBSS was verified by intravenous administration in a nude mouse subcutaneous tumor model. A subsequent characterization revealed that GEBSS exhibited a concentrated size distribution around 142\u00a0nm, were efficiently absorbed by colorectal cancer (CRC) cells, and demonstrated inhibitory effects on tumor cell proliferation. In vivo experiments demonstrated excellent tumor-targeting ability, anti-tumor efficacy, and biocompatibility of GEBSS. Mechanistically, GEBSS induced apoptosis and immunogenic cell death (ICD) in tumor cells. Moreover, at the epigenetic regulation level, GEBSS suppressed cell proliferation by reducing the m6A methylation levels of immune checkpoint genes PD-L1 and CD47. This study explored the feasibility of producing naturally derived nanocarriers and, for the first time, employed a combination of SHK and STM2457 for CRC treatment, offering novel strategies and insights for nanomedicine in CRC treatment."

Since these particles include cargos such as host cell-derived proteins, messenger RNAs, and micro RNAs, they serve as mediators of cell-cell communication. While the analysis of the pharmacokinetic of sEVs after the intravenous injection have been reported, the lymphatic transport of sEVs remains unclear. The objective of this study was to provide insights into the intra-lymphatic trafficking and distribution of sEVs when they are injected into an interstitial space both in normal skin tissue and in cancerous tissue. When sEVs were Subcutaneously administered into the tail base and the tumor tissue, they preferably accumulated in the lymph nodes (LNs), rather than in the liver and the spleen. The findings reported herein show that the lymphatic transport of sEVs was drastically changed in model mice, in which a surgical treatment was used to modify to allow the dominant lymphatic flow from the footpad directly to the axillary LN via the inguinal LN. Based on the results, we conclude that when sEVs are injected into the subcutis space, they are preferably delivered to the LN via the lymphatic system. Further, the extent of accumulation of sEVs in the LN after subcutaneous injection was reduced when they were preliminarily incubated with Proteinase K. These results suggest that the lymphatic drainage of sEVs in normal skin tissue is regulated by membrane proteins on their surface. This reduction, however, was not observed in the case of cancer tissue. This discrepancy can be attributed to the presence of highly permeable lymphatic vessels in the tumor tissue. Further, the major cell subtypes that captured sEVs in the LN were LN-resident medullary sinus macrophages. These collective findings indicate that the lymphatic drainage of sEVs are mediated by proteins and, that they may appear to contribute to the control of the function of immune-responsive cells in the LNs."

This study compares 3 commercially available plant derived extracellular vesicle formulations; Exoline, Glow, and Elysee, administered alone or with LLLT, in a rabbit ear wound model.

Exosomes, nanoscale extracellular vesicles derived from mesenchymal stem cells and dermal papilla cells (DPCs), offer a promising regenerative alternative by modulating key hair-growth pathways. This systematic review evaluates the efficacy, mechanisms, and translational challenges of exosome-based therapies for hair restoration in AGA. A comprehensive search was conducted across Google Scholar, Embase, PubMed, Scopus, and Web of Science for studies published from 2019 to 2025. The search strategy prioritized AGA-related terminology, including androgenetic alopecia, male pattern hair loss, female pattern hair loss, baldness, exosomes, extracellular vesicles, and hair regrowth. Following duplicate removal, 39 studies meeting Population, Intervention, Comparison, Outcome, and Study design criteria were included for qualitative synthesis. Preclinical data demonstrate that exosomes promote hair regeneration through multiple synergistic mechanisms: activation of the Wnt/beta-catenin and Sonic Hedgehog pathways, suppression of transforming growth factor beta (TGF-beta)/SMAD3 signaling, delivery of anti-inflammatory cytokines (e.g., IL-10), and rejuvenation of senescent DPCs via microRNA cargo (e.g., miR-122-5p). Early clinical studies report improvements in hair density (8-20%) and shaft thickness; however, the evidence base remains limited by small sample sizes, retrospective designs, lack of control groups, and inconsistent outcome measures. Emerging delivery systems, such as thermoresponsive hydrogels and microneedle patches, show promise in enhancing follicular penetration but require further validation. Exosome therapy represents a multi-target regenerative approach for AGA with a favorable preliminary safety profile. However, widespread clinical adoption is hindered by critical gaps in manufacturing standardization, scalability, regulatory frameworks, and robust long-term efficacy data. Future research must prioritize large-scale randomized controlled trials with standardized endpoints and Good Manufacturing Practice (GMP)-compliant production protocols to validate these findings and establish exosomes as a mainstream therapeutic option for AGA."

Lipid nanoparticles (LNPs) are a standard delivery carrier. However, LNPs often accumulate in the liver and exhibit transient protein expression. These limitations can restrict their safety and immunogenic potential. Here, we developed a modular, peptide-based nanocomplex to overcome the current limitations. The system comprises three functional peptides: an RNA-binding peptide (RBP) for condensation, l-polyglutamic acid (PGA) for charge modulation, and an APC-targeting cell-penetrating peptide (A-CPP). This A-CPP features a newly discovered 7-mer immune cell-binding motif identified in this study. We optimized the physicochemical properties by systematically fine-tuning the ratios of these peptide modules. The optimized nanocomplex formed stable particles under 200\u202fnm. Unlike LNPs, which showed significant liver accumulation, the peptide-nanocomplexes remained localized at the injection site and effectively drained to the lymph nodes. Furthermore, the peptide-nanocomplex retained mRNA expression for up to 7 days in vivo, whereas LNP-mediated expression diminished within 48\u202fh. In mice immunized with SARS-CoV-2 spike mRNA, this prolonged antigen exposure elicited robust neutralizing antibody titers comparable to LNPs. Notably, the peptide-nanocomplex induced significantly higher CD8+ T cell responses than LNPs. Moreover, the peptide-nanocomplex demonstrated an excellent safety profile in vivo with no toxicity observed even after daily injections for two weeks at doses up to 200 times higher. This study establishes a data-driven fine-tuning strategy for peptide-based mRNA delivery. The resulting peptide-nanocomplex offers a safer, lymph node-targeted, and longer-lasting efficacy alternative to lipid-based carriers for next-generation vaccines."

Nanocrystals, nanosuspensions, lipid vesicles, polymeric nanoparticles, nanogels, extracellular vesicles, and lipid nanoparticles have been integrated with coated, dissolving, hollow, and hydrogel-forming microneedles for local and systemic delivery. Here, integrated colloid-loaded microneedles refer to systems in which colloidal carriers are coated onto, incorporated into, infused through, or reservoir-coupled with microneedle platforms, whereas solid microneedle pretreatment followed by topical colloid application is discussed only as a microneedle-assisted comparator. For integrated colloid-loaded microneedles, performance is not determined solely by microneedle geometry, insertion efficiency, or drug loading, but rather by whether the carrier survives conversion into a microneedle product and remains functionally relevant after hydration and release in skin. Existing reviews mainly emphasize microneedle materials, fabrication strategies, therapeutic applications, or smart devices, whereas the colloidal determinants of performance remain less integrated. Unlike application-centered or platform-centered reviews, this review focuses on the state transitions and functional persistence of colloidal carriers across fabrication, storage, insertion, hydration, redispersion, and dermal biointerfacial transport. We therefore reframe these products as formulation-device-biointerface systems, with emphasis on carrier integrity, matrix compatibility, redispersion, and post-insertion fate as determinants of therapeutic performance. To support mechanism-based evaluation, we further propose a study-level evidence hierarchy and practical analytical/QbD framework for assessing intact carrier delivery, redispersibility, bioactivity, and translational quality attributes. Issues related to biologic stability, sterilization, storage, manufacturing scalability, regulatory complexity, and critical quality attributes are also discussed within a quality-by-design framework."

In this study, a methacrylated gelatin (GelMA)-based microneedle system was developed for the efficient transdermal delivery of extracellular vesicles derived from Polygonatum kingianum (PkEVs) to prevent UVB-induced skin photoaging. The PkEVs exhibited a typical spherical morphology, with an average diameter of 168.2\u00a0\u00b1\u00a010.1\u00a0nm, and were successfully incorporated into a GelMA-based microneedle system (Pk@MN) for transdermal delivery. Pk@MN exhibited sufficient mechanical strength, with a breaking force of approximately 0.36\u00a0N per needle, and showed a rapid PkEV release profile, with approximately 90% of PkEVs released within 10\u00a0min. In vitro, Pk@MN effectively inhibited UVB-induced oxidative stress and cellular senescence in HaCaT cells, as indicated by reduced intracellular reactive oxygen species (ROS) levels and decreased senescence-associated \u03b2-galactosidase (SA-\u03b2-Gal) positive cells. Pk@MN also suppressed LPS-induced inflammatory responses in RAW264.7 cells. In vivo, pretreatment with Pk@MN markedly inhibited UVB-induced skin photoaging in mice, maintained skin elasticity by suppressing epidermal thickening, and promote dermal collagen deposition, with a 2.1-fold increase in collagen density compared with the Model group. Moreover, Pk@MN significantly suppressed the expression of the proinflammatory cytokine interleukin-6 (IL-6), approaching the level observed in the Control group. Transcriptome sequencing analysis further suggested that the protective effects of Pk@MN were associated with the regulation of pathways related to inflammation, oxidative stress, and tissue repair. This study highlights a GelMA-based microneedle platform for efficient transdermal delivery of plant-derived extracellular vesicles and provides a promising strategy for preventing UVB-induced skin photoaging."

Aluminum and lipid nanoparticles have been used for this purpose, but their accumulation or widespread circulation in the body can lead to adverse effects. In contrast, physical adjuvants, which use physical energy to transiently stress tissues, do not persist in exposed tissues or cause lasting adverse effects. Herein, we investigate the effects of intradermal injection of endotoxin-free ovalbumin (OVA) protein alone without additional adjuvants using a needle-free pyro-drive jet injector (PJI) on tumor vaccination efficacy. Intradermal injection of OVA protein alone using PJI significantly increased OVA-specific CD8+ T cell expansion in the lymph node, although lymph node swelling was much less than when aluminum hydroxide was used. The injection also induced OVA-specific killing activity and antibody production and showed strong CD8+ T cell-dependent prophylactic antitumor effects against transplanted E.G7-OVA tumors. In particular, intradermal injection of the fluorescent OVA protein significantly enhanced its uptake by XCR1+ dendritic cells, which have a strong ability to cross-present extracellular proteins in the skin and draining lymph nodes. In addition, the injection increased the expression of HMGB1, one of the potent danger signals whose expression has been reported to increase in response to shear stress. Thus, intradermal injection of OVA protein alone without any additional adjuvants using PJI induces potent CD8+ T cell-mediated antitumor immunity by enhancing its uptake into XCR1+ dendritic cells, which have a high cross-presentation capacity accompanied by an increased expression of shear stress-induced HMGB1."

Traditional vaccine platforms, such as live-attenuated or inactivated pathogens, although immunogenic, often present safety concerns. Conversely, subunit vaccines, despite being safer, generally exhibit poor immunogenicity due to inadequate delivery of antigens to professional antigen-presenting cells (APCs). To address this issue, the development of innovative delivery systems has become a pivotal strategy to overcome significant biological barriers, including extracellular antigen degradation, suboptimal lymph node targeting, and inefficient cross-presentation necessary for CD8+ T cell activation. This review systematically explores recent advancements in delivery technologies aimed at enhancing antigen presentation, encompassing rationally engineered nanocarriers and sophisticated biomimetic platforms. We first examine how nanoparticle properties like size, surface charge, and ligand density affect intracellular trafficking and the transition from MHC-II to MHC-I cross-presentation. Then, we explore bioinspired systems such as extracellular vesicles, virus-like particles, and cell-membrane-coated nanoparticles that utilize natural biological traits for enhanced targeting and immune modulation. Additionally, we review new physical delivery methods like microneedle arrays and in situ electroporation for direct, minimally invasive antigen delivery to dendritic cells. Lastly, we discuss the potential of these platforms in personalized cancer vaccines and combination immunotherapies. By combining insights from materials science, immunology, and bioengineering, these next-generation delivery tools could enhance antigen presentation and transform precision vaccination and immune intervention."

We previously reported that anionic carboxyl-terminal dendrimers were accumulated in lymph nodes. In this study, three anionic dendrimers with carboxyl-, sulfonyl-, and phosphate-terminal groups were prepared to examine the lymph node targeting and the association with immune cells in the lymph nodes. These anionic dendrimers were accumulated in the lymph node by intradermal injection. Although the carboxyl- and sulfonyl-terminal dendrimers were diffused from the injection site, the phosphate-terminal dendrimers were mostly retained. The phosphate-terminal dendrimer was recognized by the macrophages, dendritic cells, and B cells in the lymph node, whereas the carboxyl- and sulfonyl-terminal dendrimers were not. Our results show that these anionic dendrimers were accumulated in the lymph node where the association with immune cells could be controlled by the terminal structure of the dendrimer.

To reduce the amount of contrast agents injected in patients while fully benefitting both modalities, dual-modality probes are required. This study was first aimed at developing a hybrid PET-MRI probe by labeling superparamagnetic iron oxide nanoparticles (SPIONs) with 64Cu using a fast and chelator-free conjugation method, and second, to demonstrate the ability of the agent to target sentinel lymph nodes (SLNs) in vivo using simultaneous PET-MRI imaging. High labeling efficiency of 97% produced within 10-15\u2009min was demonstrated at room temperature. 64Cu-SPIONs were chemically stable in mouse serum for 24\u2009h and after intradermal injection in the hind paw of C57BL/6J mice, demonstrated specific accumulation in the SLN. Simultaneous PET-MRI clearly demonstrated visualization of 64Cu-SPIONs, in dynamic and static imaging sequences up to 24\u2009h after administration. The use of a single hybrid probe and simultaneous hybrid imaging provides an efficient, complementary integration of quantitation and is expected to improve preoperative planning and intraoperative guidance of cancer treatments."

Herein, we developed an innovative nanoprobe based on well-defined core crosslinked star (CCS) polymers for non-invasive fluorescence imaging of SLN. A well-defined biodegradable CCS polymer comprising multiple polyethylene glycol (PEG) arms and carboxyl terminal groups (denoted as CCS-COOH) was synthesized successfully by reversible addition-fragmentation chain transfer polymerization with a disulfide-based crosslinker reagent. Besides, CCS-COOH was coupled by tert-butyl carbazate to produce the CCS derivative with neutral butoxycarbonyl (Boc) terminal groups (denoted as CCS-Boc). By the removal of Boc groups, another CCS derivative with positive primary amino terminal groups (denoted as CCS-NH2) was also yielded. These CCS polymers had similar particle size but different surface charge. For SLN fluorescence imaging, the CCS polymers labeled by CY7, a near-infrared probe, exhibited superior in vitro photo-stability to CY7 alone. After intradermal injection of the CY7-labeled CCS polymers in a mouse model, they could efficiently accumulate in the lymph node of the mouse. CY7-labeled CCS-COOH having negatively-charged surface displayed longer duration time and higher fluorescence intensity in the lymph node as compared to its counterparts with neutral or positive charge surface. In vitro and in vivo toxicity tests supported low cytotoxicity of these CCS polymers against cell lines and low systemic toxicity.

It is the first organized immune-stromal site exposed to lymph-borne melanoma-derived extracellular vesicles (EVs), soluble mediators, proteins, lipids, and non-coding RNAs (ncRNAs) before and during metastatic seeding. Current evidence supports a model in which melanoma-derived EVs traffic through lymphatic vessels, enter draining nodes, interact with lymphatic endothelial cells, medullary macrophages, dendritic cells, and T cells, and remodel lymphovascular, stromal, and immune compartments. Key vesicle-associated mechanisms include NGFR/p75NTR-positive small extracellular vesicles (sEVs) that drive lymphangiogenesis and nodal metastasis, PD-L1-positive vesicles that suppress T-cell activation, CD36-linked pathways that reshape myeloid lipid metabolism, and uPAR-associated vesicles that promote endothelial and matrix remodeling. EV-associated miRNAs, lncRNAs, and circRNAs may further regulate fibroblast activation, macrophage behavior, MAPK/ERK signaling, PTEN-related stromal restraint, glycolysis, autophagy, and tumor-suppressive pathways. This review integrates clinical SLN biology, lymphatic vesicle trafficking, cargo-specific protein and ncRNA pathways, immune tolerance, stromal remodeling, multi-omic profiling, and therapeutic interception. Comparative evidence from cutaneous squamous cell carcinoma and Merkel cell carcinoma broadens the field, but direct evidence linking lymphatic EVs to SLN remodeling remains strongest in melanoma."

"abstract_text": "ID: 42338019\nTitle: Exosomal Oleic Acid Promotes Lymphangiogenesis and Nodal Metastasis in Cervical Cancer via the AKT/mTOR Pathway.\nAbstract: Cervical cancer (CC) exhibits a pronounced tropism for regional lymphatic dissemination, a process driven by tumor-associated lymphangiogenesis. While metabolites within the metastatic niche are increasingly recognized as determinants of organotropic metastasis, the role of exosome-mediated metabolite transfer in tumor-lymphatic endothelial cell (LEC) crosstalk remains largely unexplored. Here, we demonstrate that oleic acid (OA) is significantly enriched in both CC lymph node metastases and the peritumoral lymphatic microenvironment. Exosomes derived from highly metastatic CC cells actively package OA in a manner dependent on stearoyl-CoA desaturase (SCD), the rate-limiting enzyme of de novo fatty acid synthesis. Upon internalization by LECs, exosomal OA triggers the AKT/mTOR signaling axis, eliciting robust LEC proliferation and endothelial-to-mesenchymal transition (EndMT), thereby fostering lymphangiogenesis and nodal colonization. Knockdown of SCD abolishes these pro-lymphangiogenic effects, a deficit fully reversed by the reconstitution of OA-loaded exosomes. In vivo, exosomes from SCD-silenced cells exhibit a severely compromised capacity to drive primary tumor growth, intratumoral lymphangiogenesis, and lymph node metastasis (LNM). Notably, free OA administration exerts substantially weaker effects than its exosomal counterpart, underscoring the superior efficiency of exosome-mediated metabolite trafficking. Clinically, FASN and SCD expression are significantly upregulated in lymph node-positive specimens and positively correlate with lymphatic vessel density and p-AKT levels. Furthermore, circulating exosomal OA levels are significantly elevated in patients with nodal involvement, suggesting its potential as a non-invasive diagnostic biomarker. Collectively, our findings establish a paradigm wherein tumor-derived exosomes function as specialized vehicles for intercellular OA transfer, activating the AKT/mTOR pathway to license lymphangiogenic reprogramming. This work identifies exosomal metabolite shuttling as a central node in tumor-lymphatic communication and proposes targeting OA synthesis or exosomal delivery as a promising therapeutic strategy against CC metastasis."

BC-derived exosomes influence intercellular communication within the tumor microenvironment, driving metastatic progression. However, the precise mechanisms by which exosomes facilitate LN metastasis in BC remain unclear. We performed small RNA sequencing on serum exosomes to identify Piwi-interacting RNAs (piRNAs) associated with BC LN metastasis. Functional investigations of exosomal piR-hsa-28212 included in\u00a0vitro assays for migration and tube formation of human lymphatic endothelial cells (HLECs), alongside an in\u00a0vivo footpad-popliteal LN metastasis model. Specific interactions between piR-hsa-28212 and TBX1 (T-box transcription factor 1), as well as TBX1 and VEGF receptor 3 (VEGFR3), were validated through luciferase reporter assays. The stability of TBX1 mRNA was analyzed by actinomycin D assay. RNA pulldown, RNA immunoprecipitation (RIP), and RNA fluorescence in\u00a0situ hybridization (FISH) assays were conducted to explore the interaction between piR-hsa-28212 and METTL3. PiR-hsa-28212 was significantly upregulated in serum exosomes of BC patients with LN metastasis.

Mechanistically, exosomal piR-hsa-28212 transferred from BC cells to HLECs stabilized TBX1 mRNA, thereby upregulating VEGFR3 expression. In BC cells, piR-hsa-28212 directly bound to and stabilized METTL3 protein, modulating N6-methyladenosine (m6A) methylation of vascular endothelial growth factor C (VEGFC) mRNA and consequently increasing VEGFC expression and secretion. Collectively, these findings reveal an exosome-mediated piRNA regulatory mechanism that synergistically amplifies VEGFC/VEGFR3 signaling to drive LN metastasis in BC, highlighting piR-hsa-28212 as a potential therapeutic target.

Popliteal lymphatic metastasis model was constructed in Balb/c mice. Histological examinations were conducted using hematoxylin and eosin (HE) and Immunohistochemical staining. Flow cytometry detected M1/M2 polarization markers. Immunofluorescence staining tested distribution of interleukin enhancer binding factor 3 (ILF3) and YBX1 and macrophage markers. Transwell and tube formation assays assessed migration and angiogenesis. Enzyme-linked immunosorbent assay (ELISA) measured C-X-C motif chemokine ligand 8 (CXCL8), transforming growth factor beta (TGF-\u03b2), vascular endothelial growth factor A (VEGFA) and macrophage markers. Levels of mRNA and protein were measured by RT-qPCR and Western blot. Subcellular localization of ILF3 and CXCL8 was detected utilizing fluorescence in situ hybridization (FISH) assay. Exosomes derived from BCa cells were isolated and identified. RNA immunoprecipitation (RIP) and Co-immunoprecipitation (Co-IP) validated molecular interactions. Knockdown of YBX1 in BCa cells suppressed lymphangiogenesis in vitro and in vivo and reduced M2 macrophage polarization. CXCL8 levels, elevated in BCa patients, were positively correlated with YBX1 and M2 macrophage infiltration, and this elevation was reduced upon YBX1 knockdown.

Extracellular matrix (ECM) remodeling aways accompany with chemotherapy, but its role in chemotherapy-associated metastasis is still unclear. Here, we reveal hyaluronidase-driven degradation of hyaluronic acid (HA) as a key mechanism underlying chemotherapy-associated lymphatic metastasis in gastric cancer. We found that chemotherapy-associated lymphatic metastasis of gastric cancer occurred during neoadjuvant chemotherapy in both patients and nude mice. The proportion of HA increased significantly in ECM during chemotherapy. We also found that cell migration inducing hyaluronidase 2 (CEMIP2) is the most highly expressed hyaluronidase to degrade HA into its effective type, low molecular weight HA (LMWHA), and promoted chemotherapy-associated lymphatic metastasis of gastric cancer. Mechanistically, CEMIP2-generated LMWHA activates CD44-ATF3 signaling to transcriptionally upregulate TGF\u03b2 receptor TGFBR1, driving metastasis. CEMIP2 is highly expressed in gastric epithelium naturally.

Lymphatic small extracellular vesicles (sEVs) derived from melanoma play a crucial role in establishing a premetastatic niche (PMN) within the sentinel lymph node (SLN). Therefore, analyzing the proteomic content of tumor-draining lymphatic sEVs that deliver oncogenic signals to the SLN is vital in understanding the PMN. To investigate this, we performed multiplexing (18 samples) using tandem mass tag labeling to profile the lymphatic sEV proteomes obtained from afferent lymphatic channels leading to the SLN of melanoma patients (n = 6), non-cancer-associated afferent lymphatic channels (n = 3), and postoperative lymphatic fluid after LN dissection (n = 9). We identified 595 new proteomic cargoes compared with those reported in ExoCarta and 1003 new cargo proteins relative to three previously reported lymphatic EV datasets. The analysis revealed 145 differentially expressed proteins of melanoma sEVs that link to increased cellular stress and injury pathways and a decrease in extracellular matrix organization (-log[p value] >7.0). Analysis of the top 50 differentially expressed proteins included expressions of normal, primary, and metastatic samples across multiple omics datasets. Hierarchical clustering with postoperative samples demonstrated nine upregulated and two downregulated proteins specific to melanoma sEVs, which are associated with melanoma progression (p < 0.05). Notably, several common proteins associated with melanoma and postoperative samples were related to the wound healing mechanism. The multiplex immunofluorescence analysis of selected proteins reveals significantly increased expression levels of CD38, galectin-9 (LGALS9), and tenascin-C (TNC) in the lymphatic sinuses of SLN (-) compared with the control LN sinuses. Moreover, higher levels of LGALS9 protein in LN tissue are associated with poor overall survival of melanoma patients (p = 0.0018). In summary, this study reveals an altered landscape of sEV proteome in the afferent lymphatic fluid of melanoma, highlighting distinct sEV proteins that are uniquely present in the SLN during PMN development."

Cancer associated fibroblasts (CAFs), major cell components in the TME, exert significant effects on malignant behaviors of various cancers. Triple negative breast cancer (TNBC) is the most malignant subtype of breast cancer with a high metastatic potential and poorer prognosis. However, the underlying mechanism by which CAFs promote TNBC development has not been sufficiently studied. The study aims to elucidate how CAFs promote TNBC aggressiveness by delivering protein-coding circMIB1 to activate MIB1/DLL4/Notch pathway, and provide a potential clinical biomarker for TNBC management. The oncogenic exosomal circMIB1 with protein-coding potential was identified through high-throughput RNA sequencing and ribosome nascent-chain complex sequencing (RNC-seq). The enrichment of circMIB1 in CAFs was confirmed using in situ hybridization (ISH) and qRT-PCR. The protein-coding capacity of circMIB1 was validated based on the polysome profiling, and luciferase assays.

Mechanistically, MIB1-223aa competitively bound to the E3 ubiquitin ligase RNF213, which blocked the RNF213-mediated K48-linked ubiquitination and degradation of MIB1. Moreover, the stabilized MIB1 enhanced the Notch signaling via a ubiquitination-dependent activation of the ligand DLL4, thereby driving TNBC malignancy. Clinically, high expression of circMIB1 or MIB1-223aa in TNBC tissues was correlated with poor clinical prognosis, as evidenced by reduced overall survival, shortened disease-free survival, and elevated lymphatic metastasis rates. This study provides the first evidence of exosome-transmitted protein-coding circRNAs in CAF-TNBC crosstalk, offering novel insights into the TME-driven metastasis and providing promising biomarker for TNBC management."

Using micromanipulator-assisted isolation of rare DCCs, single-cell mRNA and DNA sequencing, codetection by indexing immunofluorescence imaging and survival analysis, we identified melanoma-associated chondroitin sulfate proteoglycan (MCSP)+ melanoma cells as metastasis founder cells (MFCs). We found that DCCs entering SLNs predominantly exhibited a transitory phenotype that, upon interferon-\u03b3 exposure triggered by CD8 T cells, dedifferentiated into a neural-crest-like phenotype. This was accompanied by increased production of small extracellular vesicles (sEVs) carrying the immunomodulatory proteins CD155 and CD276 but rarely programmed cell death protein 1 ligand 1. The sEVs suppressed CD8 T cell proliferation and function, facilitating colony formation. Targeting MCSP+ MFCs or their immune escape mechanisms could be key to curing melanoma early by preventing manifestation of metastasis."

Many factors contribute to this dilemma, including lymphatic metastasis, which is the primary cause of PDAC metastasis. The inhibition of early lymph node metastasis, including the lymphangiogenic process, may be a novel strategy for PDAC treatment. Through miRNA sequencing of plasma extracellular vesicles (EVs) from PDAC patients, for the first time, we identified that plasma EV-miR-205-5p served as a non-invasive biomarker distinguishing lymphatic metastasis status (N0 vs. N2) in PDAC patients. Using tissue microarray and in situ hybridization, we discovered that miR-205-5p was highly expressed in PDAC, but negatively correlated with lymph node metastasis. By in vivo and in vitro experiments, we demonstrated its unique mechanism of action via EV-mediated transfer to human lymphatic endothelial cells (HLECs), leading to systematic downregulation of VEGFA and inhibition of the Akt/Erk pathway, which suppressed lymphangiogenesis. Delivering miR-205-5p via engineered EVs might be a promising strategy to eliminate PDAC lymphatic metastasis and improve prognosis."

However, the immunosuppressive microenvironment of TDLNs propels the formation of pre-metastatic niche, in which the immunocytes are dysfunctional, and the high expression of programmed death-ligand 1 (PD-L1) on dendritic cells (DCs) restricts the activation of cytotoxic T lymphocytes. Herein, engineered exosomes (EmDEX@GA) are developed for locoregional immunomodulation of TDLNs. EmDEX@GA possess CC-chemokine receptor 7 (CCR7) -dependent LN homing capacity and over-expressed programmed cell death protein 1 (PD-1) for immune checkpoint blockade (ICB). The loaded stimulator of interferon genes (STING) agonist can reinforce anti-tumor immunity through STING pathway activation. In orthotopic breast cancer mouse model, local administration of EmDEX@GA remodels the immunosuppressive microenvironment of TDLNs and elicits potent anti-tumor immunity, resulting in the suppression of tumor as well as the reduction of lymph node metastasis and distant metastasis. Compared with systemic ICB, local immunotherapy with EmDEX@GA has better therapeutic efficacy on suppressing distant metastasis. Moreover, the study suggests that the occurrences of distant metastasis are associated with the immunosuppressive microenvironment rather than the metastasis in TDLNs, indicating that targeted immunomodulation of TDLNs is necessary."

Toward that end, we engineered BIO-GEM, a hierarchically structured biomimetic lymph node (bLN) platform comprising genipin-crosslinked gelatin microspheres (GEM) encapsulating deformable albumin-hitchhiking nanoemulsions (BIO, generated with bovine albumin, imiquimod adjuvant, and OVA antigen). Compared to conventional microparticles used for immune cell recruitment, BIO-GEM forms antigen-rich depots that better recruit antigen-presenting cells (APCs) and T cells, creating an immunostimulatory niche for in situ T-cell priming. Collagenase-responsive degradation of GEM triggers sustained release of BIO, which targets LNs via the albumin-hitchhiking pathway. This spatiotemporal delivery strategy synergizes bLN-resident immune activation with LN-directed antigen trafficking, yielding high CD8+ T-cell infiltration at injection sites, dendritic cell maturation, and elicitation of antigen-specific cytotoxic T cells.

In this study, we developed a dual strategy for augmenting subunit-vaccine-induced immune responses by integrating self-adjuvanting gold nanoparticle (GNP)-antigen conjugates with implantable chitosan (CS) microneedles (MNs) to achieve sustained intradermal antigen exposure. Conjugation of a model antigen, namely, ovalbumin (OVA), onto the GNP surface (GNP-OVA) resulted in virus-mimicking multivalent antigen display, which substantially enhanced dendritic cell maturation, as evidenced by the upregulation of CD86 and major histocompatibility complex class II. This conjugation strategy also enabled the efficient codelivery of the antigen and carrier into the same antigen-presenting cells, thereby facilitating improved antigen presentation. Furthermore, compared with free OVA and a physical GNP/OVA mixture, conjugated GNP-OVA exhibited considerably longer lymph node retention, primarily because of its nanovaccine properties, which facilitate its preferential trafficking into lymphatic vessels and its subsequent accumulation in lymph nodes. Encapsulation of GNP-OVA into CS MNs (i.e., GNP-OVA MNs) resulted in reliable skin implantation, sustained intradermal antigen exposure, and local immune cell recruitment. Rat immunization studies revealed that GNP-OVA MNs induced balanced T helper 1 and T helper 2 responses and elicited considerably higher and more durable OVA-specific immunoglobulin G levels than did subcutaneous vaccination with GNP-OVA or OVA alone. These responses persisted for at least 16 weeks, highlighting the potential of the developed platform for prolonged subunit vaccine immunization. This dual-strategy platform, combining virus-mimicking GNP-based nanovaccines with immunostimulatory CS MNs, reduces reliance on external adjuvants and enhances the potency and durability of subunit vaccines. Its modular and patient-friendly design underscores its high potential for advancing the development of next-generation vaccines against emerging infectious diseases."

Like other infectious fungal diseases, it becomes even more severe when it affects immunosuppressed patients. This infection has a global distribution and is endemic in some regions of Brazil and it is an important zoonotic public health problem. The disease is caused by a complex of at least four pathogenic species, including Sporothrix brasiliensis. The immunological response against these species has not yet been completely elucidated. Still, structures such as extracellular vesicles could carry important components that can contribute to the modulation and control of this significant infection. Thus, this work aims to analyze the participation of EVs from na\u00efve dendritic cells and EVs from DCs previously primed with S. brasiliensis yeast and primed with EVs from the fungus in the immune response against experimental sporotrichosis in murine models. The groups that received EVs from DCs primed with S. brasiliensis or their EVs showed a significant decrease in fungal load compared to the negative control group. When we analyzed the cytokine profile in the skin of mice treated with EVs before infection, we observed an increase in IFN-\u213d, TNF-\u03b1, IL-17, and IL-10, mainly in animals previously treated with EVs from DCs cultivated with yeast cells. It is worth highlighting that all prophylactic protocols modulated and minimized fungal growth compared to the control; that is, EVs contributed to the control of the infection and acted in favor of the host, demonstrating a protective character."

Uptake of these nanoparticles by antigen-presenting cells was shown to induce immune tolerance in other animal models of autoimmune disease. We performed studies with C57BL/6; RAG1-/- (C57BL/6); and HLA-DQ8, huCD4 transgenic Ab0 NOD mice. Mice were given 1 or 2 tail-vein injections of TIMP-GLIA or control nanoparticles. Some mice were given intradermal injections of gliadin in complete Freund's adjuvant (immunization) or of soluble gliadin or ovalbumin (ear challenge). RAG-/- mice were given intraperitoneal injections of CD4+CD62L-CD44hi T cells from gliadin-immunized C57BL/6 mice and were fed with an AIN-76A-based diet containing wheat gluten (oral challenge) or without gluten. Spleen or lymph node cells were analyzed in proliferation and cytokine secretion assays or by flow cytometry, RNA sequencing, or real-time quantitative polymerase chain reaction. Serum samples were analyzed by gliadin antibody enzyme-linked immunosorbent assay, and intestinal tissues were analyzed by histology. Human peripheral blood mononuclear cells, or immature dendritic cells derived from human peripheral blood mononuclear cells, were cultured in medium containing TIMP-GLIA, anti-CD3 antibody, or lipopolysaccharide (controls) and analyzed in proliferation and cytokine secretion assays or by flow cytometry. Whole blood or plasma from healthy volunteers was incubated with TIMP-GLIA, and hemolysis, platelet activation and aggregation, and complement activation or coagulation were analyzed. TIMP-GLIA did not increase markers of maturation on cultured human dendritic cells or induce activation of T cells from patients with active or treated celiac disease. In the delayed-type hypersensitivity (model 1), the HLA-DQ8 transgenic (model 2), and the gliadin memory T-cell enteropathy (model 3) models of celiac disease, intravenous injections of TIMP-GLIA significantly decreased gliadin-specific T-cell proliferation (in models 1 and 2), inflammatory cytokine secretion (in models 1, 2, and 3), circulating gliadin-specific IgG/IgG2c (in models 1 and 2), ear swelling (in model 1), gluten-dependent enteropathy (in model 3), and body weight loss (in model 3). In model 1, the effects were shown to be dose dependent. Splenocytes from HLA-DQ8 transgenic mice given TIMP-GLIA nanoparticles, but not control nanoparticles, had increased levels of FOXP3 and gene expression signatures associated with tolerance induction. In mice with gliadin sensitivity, injection of TIMP-GLIA nanoparticles induced unresponsiveness to gliadin and reduced markers of inflammation and enteropathy. This strategy might be developed for the treatment of celiac disease."

The disease has a worldwide distribution, with endemic areas in Brazil, and is caused by a complex of species, including Sporothrix brasiliensis.

The aim of this study was to analyze the participation of S. brasiliensis EVs in the modulation of dendritic cells (DCs) and in the control of infection in vivo. Our results showed that in vitro, the EVs isolated from S. brasiliensis induced an increase in the phagocytic index and fungal burden in DCs. In addition, we observed a significant increase in IL-12p40 and TNF-\u03b1 cytokine production. Then, the EVs were inoculated into BALB/c mice before subcutaneous infection with yeast, and the lesion was analyzed after 21, 35, and 42 days. An increase in fungal burden and lesion diameter were observed after 21 days in mice inoculated with a high concentration of EVs. However, after 35 days, we observed a regression of the lesion, which persisted until 42 days after infection. Interestingly, we observed an increase in fungal burden in these mice. In addition, we observed the presence of immunogenic components and proteins that could be related with virulence in EVs. These results suggest that EVs can play an important role in virulence and modulation of the host immune system during experimental S. brasiliensis infection."

While current treatments either inhibit bone resorption or stimulate bone formation, their long-term use is associated with adverse effects, necessitating alternative therapeutic approaches. In this study, we explore the use of red ginseng-derived nanovesicles (RGNVs) as a biocompatible nanotherapeutic strategy for treating osteoporosis. The RGNVs were successfully isolated and characterized, revealing a lipid bilayer structure enriched in bioactive ginsenosides and functional proteins. In vitro, RGNVs enhanced osteoblast proliferation, differentiation, and mineralization while suppressing osteoclast differentiation and bone resorption by modulating the BMP-2/Smad and MAPK signaling pathways. In an ovariectomy-induced osteoporosis mouse model, oral administration of RGNVs significantly restored bone volume and mineral density, and biodistribution studies confirmed their preferential accumulation in the bone tissue. Systemic toxicity evaluation indicated no adverse effects, supporting the safety of RGNVs for therapeutic use. These findings suggest that RGNVs regulate bone remodeling through a dual mechanism, to stimulate bone formation and inhibit bone resorption, thereby offering a promising and well-tolerated approach for osteoporosis management."

Here, we report a smart TEV/PVA-PEI-PPY@GG hydrogel that integrates tomato-derived extracellular vesicles (TEV), a polypyrrole (PPY)-based near-infrared (NIR)-responsive photothermal component, and a gellan gum (GG) matrix for diabetic wound treatment. The engineered platform exhibited favorable colloidal stability, a porous and structurally integrated architecture, tunable mild photothermal responsiveness under 808\u202fnm irradiation, and retained antioxidant activity associated with the vesicular fraction. In vivo, TEV/PVA-PEI-PPY@GG significantly accelerated wound closure, improved epidermal continuity, and enhanced dermal remodeling in streptozotocin-induced diabetic wounds, while showing no obvious histopathological toxicity in major organs. Immunohistochemical and histological analyses revealed altered expression patterns of AHR, TNF-\u03b1, CD31, and CD34 in treated tissues, which may contribute to tissue repair, modulation of inflammatory responses, and angiogenic remodeling during wound healing. These changes were associated with improved wound regeneration and restoration of tissue architecture.

The present study aimed to determine whether extracellular vesicles (EVs) from adipose-derived stem cells (ADSCs) attenuated bleomycin-induced skin fibrosis and oxidative stress in scleroderma. ADSCs and their EVs were separated and a bleomycin-induced SSc mouse model was constructed. High-throughput sequencing was employed to study abnormal expression of circular RNAs in SSc skin tissues with or without ADSC-EV treatment. The regulatory mechanism and targets were studied using bioinformatics analysis, luciferase reporting analysis, angiogenic differentiation experiments, and RT-qPCR detection analysis. EVs from ADSCs were successfully isolated. The exosome treatment prevented dermal thickening and fibrosis in bleomycin-induced scleroderma. In addition, circ-Zfyve9 was demonstrated to have an important function in ADSC-EV-mediated skin tissue protection. GPX4 and miR-135 were shown to be downstream targets of circ-Zfyve9.

Current treatments remain inadequate, highlighting the need for novel, effective, and cell-free therapeutic strategies. Extracellular vesicle-enriched preparations derived from human endometrial mesenchymal stem cells (eMSC-EV-enriched preparations) may possess regenerative and anti-fibrotic potential, yet their roles in scar modulation and underlying mechanisms remain unclear. eMSCs were isolated from human endometrial biopsies and characterized via flow cytometry and differentiation assays. The eMSC-EV-enriched preparations were obtained from conditioned medium and verified by TEM, NTA, and Western blotting. Functional assays were conducted in NIH3T3 fibroblasts to assess proliferation, migration, and transwell invasion capacity. A full-thickness cutaneous wound model and a bleomycin-induced dermal fibrosis model were used in C57BL/6 mice to evaluate tissue repair and fibrosis attenuation. Histological and molecular analyses were performed to assess collagen deposition, fibrosis-associated markers, and related signaling pathways. The potential involvement of miR-125b-5p in Smad2-related signaling was explored. The eMSC-EV-enriched preparations displayed characteristic vesicular morphology and marker expression. Compared with BMMSC-EV-enriched preparations, eMSC-EV-enriched preparations more effectively reduced fibroblast proliferation and migration, with decreased transwell invasion capacity in vitro. In vivo, the eMSC-EV-enriched preparations enhanced wound closure, reduced collagen deposition, and were associated with improved collagen organization and an increased number of appendage-like structures. Expression of \u03b1-SMA and collagen I and III was reduced in tissues treated with the eMSC-EV-enriched preparations. Furthermore, the preparations were associated with increased miR-125b-5p levels and decreased Smad2/p-Smad2 expression, suggesting involvement of the miR-125b-5p/Smad2 axis. In the bleomycin model, the eMSC-EV-enriched preparations attenuated dermal thickening and collagen accumulation during fibrosis induction. Our findings indicate that eMSC-EV-enriched preparations improve repair quality and attenuate fibrosis development, potentially through modulation of fibroblast activity and involvement of the miR-125b-5p/Smad2 signaling pathway. These findings support further investigation of eMSC-EV-enriched preparations as a cell-free strategy for improving tissue remodeling in fibrotic skin conditions."

For instance, MSC-EXO promotes skin healing post-laser therapy and improves outcomes in severe COVID-19. Selecting an optimal cellular source is critical for the therapeutic development of MSC-EXO. It has been suggested that GMP-produced MSC-exosomes have slightly different molecular content. This study therefore aimed to compare adipose tissue-derived MSC-EXO (ASC-EXO) from three healthy donors, isolated and characterized under GMP conditions. Exosomes were analyzed by nano-tracking analysis (NTA), cryo-electron microscopy, tetraspanin profiling, and multi-omics (proteomics, lipidomics, small RNA sequencing), as well as bioinformatics. Functional assays quantified anti-inflammatory effects in RAW264.7 macrophages and collagen production by human dermal fibroblasts (HDF). In vivo efficacy of ASC-EXOs was evaluated in a house dust mite antigen-induced atopic dermatitis mouse model through histopathological evaluation of ear thickness and differential cell counting. No significant batch differences were observed in ASC-EXO yield or characteristics. Omics analyses revealed minor variations in protein, lipid, and small RNA cargo among the three batches, but GO-term bioinformatics indicated highly similar functional profiles. IL-6 suppression in RAW264.7 cells and cell proliferation and collagen production by HDF were similar among the ASC-EXO batches. CD73 enzymatic activity was consistent among batches. In vivo, the ASC-EXOs reduced skin thickness and eosinophilia in an atopic dermatitis model, with similar effects among the batches. In summary, ASC-EXOs from all batches demonstrated comparable anti-inflammatory and collagen-modulating effects in vitro, and similar inhibition of atopic dermatitis signs in vivo. We suggest that biological efficacy combined with bioinformatics analysis should guide MSC-EXO therapeutic quality control assays. These findings support the development of ASC-EXOs for clinical applications."

Existing technologies available for NO therapy, however, provide poor bioactivity within lymphatic tissues. In this work, we address this technology gap with a NO encapsulation and delivery strategy leveraging the formation of S-nitrosothiols on lymphatic-targeting pluronic-stabilized, poly(propylene sulfide)-core nanoparticles (SNO-NP). We evaluated in vivo the lymphatic versus systemic delivery of NO resulting from intradermal administration of SNO-NP benchmarked against a commonly used, commercially available small molecule S-nitrosothiol NO donor, examined signs of toxicity systemically as well as localized to the site of injection, and investigated SNO effects on lymphatic transport and NP uptake by lymph node (LN)-resident cells. Donation of NO from SNO-NP, which scaled in proportion to the total administered dose, enhanced LN accumulation by two orders of magnitude without substantially reducing lymphatic transport of NP or the viability and extent of NP uptake by LN-resident cells. Additionally, NO delivery by SNO-NP was accompanied by low-to-negligible NO accumulation in systemic tissues with no apparent inflammation.

While there is great interest in targeted drug delivery to LNs, many nanoscale drug delivery carriers have limited access to parenchymal resident immune cells compared to small molecules, limiting their efficacy. Nitric oxide (NO) is a potent regulator of vascular and lymphatic transport and a promising candidate for modulating nanocarrier access to LNs, but its lymphatic accumulation is limited by its low molecular weight and high reactivity. In this work, we employ S-nitrosated nanoparticles (SNO-NP), a lymphatic-targeted delivery system for controlled NO release, to investigate the effect of NO application on molecule accumulation and distribution within the LN. We evaluated the LN accumulation, spatial distribution, and cellular distribution of a panel of fluorescent tracers after intradermal administration alongside SNO-NP or a small molecule NO donor. While SNO-NP did not alter total tracer accumulation in draining lymph nodes (dLNs) or affect active cellular transport of large molecules from the injection site, its application enhanced the penetration of nanoscale 30\u00a0nm dextrans into the LN and their subsequent uptake by LN-resident lymphocytes, while nontargeted NO delivery did not. These results further extended to a peptide-conjugated NP drug delivery system, which showed enhanced uptake by B cells and dendritic cells when administered alongside SNO-NP. Together, these results highlight the utility of LN-targeted NO application for the enhancement of nanocarrier access to therapeutically relevant LN-resident immune cells, making NO a potentially useful tool for improving LN drug delivery and immune responses."

This strategy is demonstrated using chondroitin sulfate-coated nanoparticles (OPGMN) grafted with glycocholic acid and mannose for cationic liposomes encapsulated with ovalbumin as an antigen and polyinosine-polycytidylic acid as a cancer-specific adjuvant. OPGMN is absorbed in the gastrointestinal tract and delivered to the lymph nodes when orally administered. Oral delivery of OPGMN induces increased dendritic cell maturation compared to the intradermal route in the lymph node and induces T helper type 1 and type 2 responses, such as immunoglobulin G1 and G2c, interferon-gamma, and interleukin-2, in the blood. Repeated oral administration of OPGMN increases the population of CD3+ CD8+ T cells, CD44high CD62Llow memory T cells, and CD11b+ CD27+ natural killer cells in the blood. OPGMN completely prevents melanoma development in the B16F10-bearing C57BL/6 mouse model by reducing the population of CD4+ CD25+ Foxp3+ regulatory T cells in the blood.

However, few adjuvants are effective, nonreactogenic, and compatible with needle-free delivery devices. In this study, we demonstrate that a combination adjuvant composed of cyclic-di-AMP (cdAMP) and the plant-derived nanoparticle adjuvant Nano-11 significantly enhanced the immune response to ID-injected vaccines in mice and pigs with minimal local reaction at the injection site. The cdAMP/Nano-11 combination adjuvant increased Ag uptake by lymph node-resident and migratory skin dendritic cell subpopulations, including Langerhans cells. ID immunization with cdAMP/Nano-11 expanded the population of germinal center B cells and follicular helper T cells in the draining lymph node and Ag-specific Th1 and Th17 cells in the spleen. It elicited an enhanced immune response with a significant increase of IgG1 and IgG2a responses in mice at a reduced dose compared with i.m. immunization. An increased IgG response was observed following needle-free ID immunization of pigs. Nano-11 and cdAMP demonstrated a strong synergistic interaction, as shown in the activation of mouse, human, and porcine APC, with increased expression of costimulatory molecules and secretion of TNF and IL-1\u03b2. The combination adjuvant induced robust activation of both NF-\u03baB and IFN regulatory factor signaling pathways and the NLRP3 inflammasome. We conclude that the combination of Nano-11 and cdAMP is a promising adjuvant for ID delivery of vaccines that supports a balanced immune response."

We aimed to define the cellular ecosystem of MIA and to clarify the role of periostin (POSTN) and POSTN+ CAF-derived exosomes in early LUAD progression. Single-cell RNA sequencing (scRNA-seq) and tissue-derived exosomal RNA sequencing were performed on four primary MIA lesions and matched adjacent lung tissues. Integrated analyses of scRNA-seq data, exosomal transcriptomes, the TCGA-LUAD cohort, and an independent LUAD tissue/serum cohort were used to characterize POSTN expression and to evaluate its prognostic and diagnostic relevance. Primary MIA-associated POSTN+ and POSTN- CAFs were isolated for exosome preparation, followed by co-culture experiments with LUAD cell lines and xenograft assays. scRNA-seq identified a malignant Cancer-alveolar type II (Cancer-AT2) epithelial subset and multiple CAF subsets. Among these, POSTN+ CAFs were enriched in MIA tissues and showed enhanced crosstalk with Cancer-AT2 cells through extracellular matrix (ECM)-related ligand-receptor interactions. Tissue-derived exosomes contained 588 differentially expressed mRNAs, among which POSTN was markedly upregulated and showed the strongest association with fibroblast-related signatures. POSTN was predominantly expressed in fibroblasts across independent non-small cell lung cancer datasets and was elevated in LUAD tissues, tissue-derived exosomes, and serum exosomes, correlating with advanced stage, lymph node metastasis, and poor survival. Functionally, POSTN+ CAF-derived exosomes promoted LUAD cell proliferation, migration, invasion, colony formation, and xenograft growth. Exosomal POSTN derived from POSTN+ CAFs may represent an important stromal mediator of MIA/LUAD progression and a potential diagnostic and prognostic biomarker in early-stage LUAD."

Despite its clinical significance, the cellular and molecular mechanisms driving metastatic progression remain inadequately characterized, particularly the role of intercellular communication mediated by tumor-derived exosomes. We analyzed single-cell RNA sequencing (scRNA-seq) on primary and metastatic PTC tissues (n=12 samples from 4 patients), exploring cellular heterogeneity and distinct subpopulations. Metastasis-associated cell states (Scissor+ and Scissor-) were delineated using the Scissor algorithm. Pathway activity in these subpopulations was analyzed using the PROGENy algorithm.Exosomal proteomic data from lymph node metastasis patients were cross-referenced with Scissor+ signatures, identifying candidate proteins. Functional validation included in vitro angiogenesis assays with HUVECs and in vivo xenograft models to assess tumor growth and vascularization. ScRNA-seq revealed significant tumor cell heterogeneity between primary and metastatic sites, with Scissor+ cells strongly linked to metastatic phenotypes. PROGENy analysis demonstrated significant upregulation of VEGF signaling in Scissor+ cells. Among six key proteins identified, PDLIM1 was highly expressed in PTC cell lines and metastatic tissues (P < 0.001). Tumor-derived exosomal PDLIM1 was internalized by endothelial cells, enhancing angiogenesis in vitro. PDLIM1 knockdown in exosomes suppressed HUVEC tube formation (P < 0.05) and reduced tumor volume, CD31+ microvessel density, and LYVE-1+ lymphatic vessel density in xenografts (P < 0.05). Our study suggests that exosomal PDLIM1 may play a role in promoting angiogenesis and primary tumor progression in PTC. These findings provide preliminary insights into the potential involvement of exosome-mediated intercellular communication in PTC pathogenesis. Further validation in larger cohorts and functional studies, including rescue experiments, are warranted to evaluate whether targeting PDLIM1 could represent a viable therapeutic strategy."

Superficial and deep cervical lymph nodes collect CSF in mice, but the exact and quantified routes are unknown. Recently, we simultaneously visualized cervical, sacral and iliac lymph nodes via serial imaging on the intrathecal [64Cu]Cu-albumin positron emission tomography. Paravertebral lymph nodes might act as sentinels to monitor the CSF, brain, and spinal cord. We used 64Cu-labeled Escherichia coli extracellular vesicles, outer membrane vesicles (OMVs), as lymph node seekers for intrathecal administration and quantified the differential amounts of various paravertebral lymph nodes along the axis of the brain and spinal cord in mice. The quantified results revealed 77.3% in superficial and deep cervical lymph nodes, 11.4% in abdominal/pelvic lymph nodes and 11.3% in sacral lymph nodes. Click-labeled [64Cu]Cu-OMVs were drained to reach and stop at the lymph nodes on serial quantification. The cervical lymph nodes drained most of the OMV-laden CSF, which is proportional to the surface areas of the brain (70%) and spinal cord in mice. We propose that all paravertebral lymph nodes monitor the segmental regions of the brain and spinal cord as immediate sentinel lymph nodes against the central nervous system."

This study aimed to elucidate the function and mechanism of MZT2A in the metastasis of LUAD. Analysis of clinical samples and public databases revealed that MZT2A is highly expressed in LUAD tissues and significantly associated with lymph node metastasis, advanced stage, and poor prognosis. In vitro functional assays revealed that MZT2A overexpression significantly enhanced the invasion, migration, and adhesion of LUAD cells and induced epithelial-mesenchymal transition (EMT). Mechanistically, via its MOZART2 domain, MZT2A interacts with the SRCR domain of galectin-3-binding protein (LGALS3BP), promoting the sorting of LGALS3BP into exosomes and its subsequent secretion. Secretory LGALS3BP acts as a ligand, binding to integrin beta-1 (ITGB1) on the cell membrane through its BTB domain, thereby activating the downstream TGF-\u03b2/smad2 signaling pathway to drive EMT and metastatic phenotypes. Molecular docking and mutation experiments confirmed these critical domain interactions. In vivo experiments also validated that MZT2A overexpression promoted pulmonary metastasis, while LGALS3BP knockdown reversed this effect.

In this study, we indicate that Ephrin type-A receptor 2 (EphA2) is heterogeneously expressed in gastric cancer (GC) tumor cells, with those exhibiting elevated EphA2 (EphA2High) expression demonstrating enhanced migratory and invasive capabilities. EphA2High cells facilitate the transfer of EphA2 via exosomes, which subsequently localize on the membrane of EphA2Low cells, thereby activating the ERK signaling pathway in a ligand-independent manner. This process promotes the transformation of EphA2Low cells and contributes to the progression of GC. An investigation into the correlation between serum levels and tumor metastasis in patients with GC revealed that those with lymph node metastasis exhibited higher levels of serum exosomal EphA2.

Prior work has shown that lymphatics transport 10-250 nm nanoparticles from peripheral tissues to the lymph node. However, the surface chemistry required to maximize this transport is poorly understood. Here, we determined the effect of surface poly(ethylene glycol) (PEG) density and size on nanoparticle transport across lymphatic endothelial cells (LECs) by differentially PEGylated model polystyrene nanoparticles. Using an established in-vitro lymphatic transport model, we found PEGylation improved the transport of 100 and 40 nm nanoparticles across LECs 50-fold compared to the unmodified nanoparticles and that transport is maximized when the PEG is in a dense brush conformation or high grafting density (Rf/D\u00a0=\u00a04.9). We also determined that these trends are not size-dependent. PEGylating 40 nm nanoparticles improved transport efficiency across LECs 68-fold compared to unmodified nanoparticles. We also found that PEGylated 100 nm and 40 nm nanoparticles accumulate in lymph nodes within 4 h after intradermal injection, while unmodified nanoparticles accumulated minimally. Densely PEGylated nanoparticles traveled the furthest distance from the injection site and densely PEGylated 40 nm nanoparticles had maximum accumulation in the lymph nodes compared to low density PEGylated and unmodified nanoparticles. Finally, we determined that nanoparticles are transported via both paracellular and transcellular mechanisms, and that PEG conformation modulates the cellular transport mechanisms. Our results suggest that PEG conformation is crucial to maximize nanoparticle transport across LECs and into lymphatic vessels, making PEG density a crucial design. Optimizing PEG density on nanoparticle formulations has the potential to enhance immunotherapeutic and vaccine outcomes. STATEMENT OF SIGNIFICANCE: Lymphatic vessels are an emerging target for drug delivery both in the context of modulating immune responses and enhancing bioavailability by avoiding first pass hepatic metabolism after oral delivery. Lymphatic vessels are the natural conduits from peripheral tissues to the lymph nodes, where the adaptive immune response is shaped, and eventually to systemic circulation via the thoracic duct. Lymphatics can be targeted via nanoparticles, but the surface chemistry required to maximize nanoparticle transport by lymphatics vessels remains poorly understood. Here, we demonstrate that coating nanoparticles with hydrophilic polyethylene glycol (PEG) effectively enhances their transport across lymphatic endothelial cells in vitro and in vivo and that both paracellular and micropinocytosis mechanisms underly this transport. We found that dense PEG coatings maximize lymphatic transport of nanoparticles, thus providing new material design criteria for lymphatic targeted drug delivery."

Probiotics and postbiotics represent promising preclinical candidates to alleviate these unmet clinical bottlenecks. Bacterial extracellular vesicles (BEVs) are naturally secreted bacterial nanovesicles carrying abundant bioactive cargos, whose bioactivity and safety are highly strain-dependent. Probiotics-derived BEVs can remodel gut homeostasis, repair epithelial barriers, and regulate mucosal immunity to suppress the inflammatory vicious cycle in IBD, while pathogen-/pathobiont-derived BEVs loaded with lipopolysaccharide and virulence factors exacerbate intestinal inflammation. Native BEVs are restricted by low cargo loading, poor gastrointestinal stability and inadequate colon tropism. Rational engineering strategies, including surface modification, self-loading hybridization, genetic manipulation, and pH-responsive coating, can optimize the therapeutic performance of BEVs. This review systematically summarizes BEVs biological mechanisms, engineering approaches, and translational obstacles and outlines prospects for the design of intelligent multifunctional BEVs and standardized large-scale manufacturing as future directions, providing theoretical support for oral BEVs nanotherapies against IBD."

The liposomes maintain a negative surface charge under physiological conditions to prolong circulation, but undergo pH-responsive conversion to a positive charge within the acidic tumor microenvironment (pH 6.5-6.8), thereby improving tumor-selective internalization. The optimized formulation achieved targeted mitochondrial delivery, where IR780-induced reactive oxygen species (ROS) production and mild hyperthermia activated stress pathways, leading to mitochondrial disruption and ultimately initiating immunogenic cell death (ICD). Concurrently, encapsulated Erianin effectively suppressed photothermal therapy (PTT)/photodynamic therapy (PDT)-induced programmed cell death ligand 1 (PD-L1) upregulation. This nanoplatform not only avoids the drawbacks of conventional chemotherapy but also establishes a synergistic therapeutic framework integrating PTT, PDT, and chemotherapy.

To address these critical challenges, we developed an innovative dual-targeted nanoplatform (Exo-SPIONs-SRF/CGA) that synergistically combines the natural tumour-homing capability of HCC-derived exosomes with the magnetic guidance of superparamagnetic iron oxide nanoparticles (SPIONs) for precision drug targeting. This nanoplatform co-encapsulates SRF and CGA to improve the therapeutic index by enhancing desired responses and minimizing undesired side effects.

At the same time, the incorporated SPIONs enable external magnetic field-guided spatial control, collectively ensuring superior tumour accumulation compared to conventional delivery systems. Furthermore, the platform's tumour microenvironment-responsive release characteristics ensure localized drug activation, maximizing the therapeutic index through spatial and temporal control of drug availability. In vitro and in vivo evaluations demonstrated that this nanoplatform significantly enhances tumour suppression and drug retention while reducing systemic side effects compared to monotherapies or single-modality nanocarriers. The Exo-SPIONs-SRF/CGA platform represents a promising strategy in HCC treatment, addressing fundamental limitations of current therapies by simultaneously overcoming biological barriers to drug delivery, enhancing therapeutic efficacy through synergistic drug combinations, and minimizing collateral damage to healthy tissues, thereby advancing the frontier of precision oncology toward more effective and safer HCC management."

Moreover, the therapeutic efficacy of exosomes can be substantially enhanced through functional modifications and the incorporation of bioactive molecules. In this study, the MSCs were cultured under two-dimensional (2D) and three-dimensional (3D) cell culture conditions. The culture supernatants were collected for isolating exosomes. The characteristics and yields of exosomes from 2D and 3D cultures were detected by nanoparticle tracking analysis (NTA), transmission electron microscopy (TEM), western blot analysis, and bicinchoninic acid (BCA) assay. Subsequently, 3D exosomes were loaded with miR-99b-5p and modified with iRGD peptide were formed into a new engineered exosome, designated as iRGD-Exo-miR-99b-5p. The effects of these engineered exosomes on the progression of colorectal cancer (CRC) were assessed through a series of in vivo and in vitro experiments. The 3D-cultured MSCs exhibited a higher yield of exosomes and enhanced uptake by CRC cells. Further in vitro experiments demonstrated that 3D-exosomes loaded with miR-99b-5p effectively inhibit the proliferation, invasion, migration and epithelial-mesenchymal transition (EMT) of CRC cells. Results from a xenograft tumor model indicate that iRGD-modified exosomes were significantly enriched at tumor sites. Furthermore, exosomes modified with iRGD and loaded with miR-99b-5p were employed for CRC treatment, resulting in substantial tumor growth inhibition and enhanced the chemotherapy efficacy of 5-fluorouracil (5-FU) in vivo, without inducing notable toxicity or side effects. Mechanistically, exosome-mediated delivery of miR-99b-5p downregulated FGFR3 expression, thereby inhibiting the activation of the PI3K/AKt signaling pathway and promoting ferroptosis, ultimately attenuating CRC progression. Collectively, iRGD-modified 3D exosomes loaded with miR-99b-5p were able to specifically target tumor sites, thereby significantly suppressing CRC growth through the induction of ferroptosis via regulating the FGFR3/PI3K/AKt signaling pathway.

However, the blood-brain barrier (BBB) remains a formidable obstacle, restricting the delivery of most therapeutic molecules. To address this, we developed a non-invasive treatment strategy using engineered exosomes. Specifically, we fabricated FGF1-loaded exosomes functionalized with the rabies virus glycoprotein (RVG) peptide (FGF1-RVG Exo). This platform facilitates selective, neuron-targeted delivery of FGF1 to the ischemic penumbra via RVG-mediated transcytosis. In a diabetic stroke mouse model, FGF1-RVG Exo exhibited superior pharmacological efficacy compared to free FGF1, achieving robust therapeutic outcomes with only once-weekly administration. Notably, a single dose during the acute phase elicited a sustained hypoglycemic effect lasting up to two weeks and effectively ameliorated systemic insulin resistance. Locally, the accumulation of exosomes within the lesion led to a significant reduction in infarct volume and cell apoptosis, while promoting neovascularization and the recovery of motor and cognitive functions. This brain-targeted strategy achieves a peripheral-central synergistic modulation, addressing the multi-target requirements of diabetic stroke management. Collectively, our findings provide a novel paradigm for treating diabetic ischemic stroke and a potent strategy for the targeted delivery of growth factors to the central nervous system."

While T-cell activation is implicated, the role of soluble programmed death-1 (sPD-1), primarily derived from activated T cells, in PF pathogenesis remains elusive. We initially analyzed serum sPD-1 levels in PD patients and employed a mice PF model induced by high-glucose dialysate and lipopolysaccharide (LPS). The functional impact of sPD-1 on the progression of PF was assessed through the administration of a PD-L1 fusion protein, or engineered exosomes designed to adsorb sPD-1. Serum sPD-1 levels were significantly elevated in long-term PD patients and were positively correlated with dialysis duration and markers of fibrosis, but inversely correlating with peritoneal function. In mice, exogenous sPD-1 exacerbated PF, whereas blockade with a PD-L1 fusion protein or sPD-1-adsorbing engineered exosomes markedly attenuated fibrosis, reduced T-cell infiltration, and preserved peritoneal function. Mechanistically, sPD-1 bound to PD-L1 on PMCs, triggering clathrin-mediated endocytosis. This interaction diverted PD-L1 from the lysosomal degradation pathway towards the Rab11-positive recycling endosome pathway, resulting in sustained upregulation of surface PD-L1 expression. This aberrant PD-L1 recycling activated pro-fibrotic signaling, culminating in mesothelial-to-mesenchymal transition (MMT). sPD-1 is a pivotal mediator linking peritoneal microinflammation to fibrosis by modulating the endocytic fate of PD-L1 in mesothelial cells. Targeting sPD-1, particularly using engineered exosomes or a PD-L1 fusion protein, represents a promising therapeutic strategy for preventing and treating peritoneal fibrosis."

Here, we report a bioinspired \"targeting and blockade\" strategy for the efficient delivery of functional Ldlr mRNA to hepatocytes. This approach is realized through a rationally designed platform, Szd\u00a0+\u00a0AP@ExoE-Ldlr, which integrates APOA1-functionalized exosomes for hepatocyte-targeted delivery with a preemptive macrophage blockade using the clinical ultrasound contrast agent Sonazoid (Szd). The APOA1 modification confers specific recognition by the scavenger receptor class B type 1 on hepatocytes, while the pre-saturation of Kupffer cells with Szd significantly mitigates nonspecific clearance by the mononuclear phagocyte system (MPS). In a HoFH murine model, this synergistic strategy markedly enhanced the accumulation of exosomes in hepatocytes and achieved robust restoration of hepatic LDLR expression. Consequently, it elicited a profound correction of the atherogenic lipid profile and substantially attenuated the progression of atherosclerosis. A comprehensive biosafety evaluation confirmed the excellent biocompatibility of this platform. Our work provides a promising and broadly applicable solution for the treatment of liver-related genetic disorders by simultaneously overcoming the critical barriers of targeted delivery and MPS evasion."

Cuproptosis has emerged as a promising mechanism by which to inhibit tumors because copper homeostasis disorders frequently occur in various malignancies. The combination of disulfiram (DSF) and copper ions (DSF/Cu) has been shown to have significant antitumor effects. This study utilized DSF/Cu to investigate the mechanism underlying cuproptosis in GC cells. GC cells were treated with DSF/Cu and protein sequencing was performed to screen for differentially expressed genes. The mechanism by which overexpressed FDX1 regulates cuproptosis and WDR43 expression was determined. Subsequently, how to improve the efficacy of DSF/Cu in the treatment of GC was studied in a mouse model of GC. DSF/Cu had a good therapeutic effect on promoting cuproptosis in GC cells. Protein sequencing revealed WDR43 as a downstream gene of FDX1. Increasing the expression of FDX1 enhanced the sensitivity of GC cells to copper treatment and inhibited the expression of WDR43, thereby exerting an antitumor effect. Furthermore, DSF/Cu was loaded into exosomes derived from natural killer (NK) cells to enhance the biological safety and tumor targeting of DSF/Cu and validate the inhibitory effect on GC both in vitro and in vivo. This study showed that DSF/Cu promoted cuproptosis and the expression of FDX1 affected cuproptosis sensitivity of GC. Moreover, the combination of NK cell exosomes with DSF/Cu improved the therapeutic effect of DSF/Cu, which helps to promote the targeted therapy of GC and improve clinical applicability."

Exosomes (Exos) are key mediators of intercellular communication and promising vehicles for targeted therapy. This study aimed to investigate the function and underlying mechanism of exercise-derived exosomes (Exe-Exos) in SCI recovery. Circulating Exos were isolated from rats subjected to a 4-week treadmill Exe regimen and from sedentary controls. A gelatin methacrylate (GelMA) hydrogel microneedles (Hyd MNs) system was developed for the targeted, sustained delivery of these Exos directly to the injury epicenter at the T10 spinal segment in a rat SCI model. Using integrated in vitro and in vivo approaches, we showed that Exe-Exos significantly promoted motor function recovery, attenuated tissue damage, reduced apoptosis, and alleviated both inflammation and oxidative stress (Oxs) after SCI. Small RNA sequencing revealed that miR-151-3p is a key functional cargo that is enriched in Exe-Exos. Gain- and loss-of-function studies revealed that exosomal miR-151-3p exerts its protective effects by directly targeting the mitochondrial membrane protein ROMO1. This targeting led to the coordinated inhibition of the pro-apoptotic JNK/Caspase pathway, suppression of the NF-\u03baB-mediated inflammatory cascade, and activation of the Nrf2/HO-1 antioxidant axis. Collectively, our findings establish Exe-Exos, specifically exosomal miR-151-3p, as an exercise-responsive circulating signaling axis that orchestrates multifaceted protection against secondary injury after SCI, offering an innovative, mechanism-based strategy for neuroregenerative therapy."

In this study, we systematically evaluated the anti-tumor effect of Bi2536, an inhibitor of Polo-like kinase 1 (PLK1), in HGSOC, and clarified its mechanism. Bi2536 inactivates PLK1, leading to the subsequent inactivation of cyclin-dependent kinase 1 (CDK1). This disruption triggers a cascade of antitumor effects, including G2/M phase arrest, induction of mitochondrial apoptosis, and suppression of cell migration and invasion. Furthermore, we identified circadian oscillations in PLK1 expression both in HGSOC cells and in vivo xenograft models. To enhance therapeutic precision and minimize systemic toxicity, we engineered a biomimetic nano-delivery system for Bi2536. This integrated platform combines chemotherapy and chemodynamic therapy (CDT), significantly improving antitumor outcomes. Importantly, synchronizing Bi2536 administration with the circadian peaks of PLK1 expression further augmented its therapeutic efficacy. In summary, our work establishes that the combination of Bi2536 with a biomimetic nano-delivery system, together with its chronotherapeutic administration, constitutes a highly promising and multifaceted strategy for the treatment of HGSOC."

In recent years, nanotechnology has provided a new strategy for the treatment and diagnosis of IBD due to its advantages of precise delivery, controllable release and multifunctional integration. We searched the Web of Science Core Collection database for relevant literature about nanotechnology and IBD published from 2005 to 2024. We used SciExplorer, VOSviewer, and Citespace to analyze countries, institutions, authors, keywords, highly cited references, and co-cited references to discuss research hotspots and trends in this field. The research analysis included a total of 959 pieces of literature, with China and the USA leading in the number of papers published and academic influence.

Here we successfully synthesized curcumin (CUR) loaded polyethylene glycol (PEG) functionalized magnetic iron oxide nanoparticles (Fe3O4@PEG-CUR-NPs) by a green biogenic approach using Hibiscus rosa-sinensis flower extract and evaluated as a multifunctional platform for controlled drug delivery and cancer therapy. UV-Vis, FTIR, PXRD, SEM, TEM, DLS, TGA and VSM characterizations have been performed comprehensively to confirm the successful fabrication of crystalline, spherical nanoparticles with average size of 10-15\u00a0nm, excellent colloidal stability (zeta potential\u2009-\u200931.5\u00a0mV) and retained magnetic responsiveness with saturation magnetization of 28.30\u00a0emu/g.

Cuproptosis, a non-apoptotic cell death modality, has emerged as a promising alternative, yet its therapeutic efficacy is frequently limited by robust intracellular antioxidant defense systems. Here, we developed an ultrasmall (ca.10\u202fnm) mitochondria-targeted bimetallic nanozyme (RMOCZ) for synergistic ferroptosis-cuproptosis therapy against malignant melanoma. The Cu/Zn bimetallic core, functionalized with a chimeric mitochondrial targeting peptide, serves as both a pH-responsive copper reservoir and a dual-enzyme mimetic (peroxidase and glutathione oxidase). Upon endolysosomal acidification, RMOCZ disassembles to co-release copper ions and oridonin (ORI). The nanozyme oxidizes intracellular glutathione (GSH), a process significantly accelerated by co-delivered ORI. This disruption of redox homeostasis not only triggers ferroptosis by compromising cellular antioxidant capacity but also amplifies peroxidase-mediated reactive oxygen species (ROS) production, sensitizing tumor cells to copper-induced cytotoxicity. Concurrently, RMOCZ induces ferritinophagy to mobilize the endogenous labile iron pool and exacerbate lipid peroxidation. These events culminate in sustained copper-iron dual-ion overload. Following subsequent mitochondrial trafficking, the accumulated copper ions trigger canonical cuproptotic events, including the degradation of iron-sulfur (Fe-S) clusters and aberrant oligomerization of lipoylated DLAT. This irreversible mitochondrial dysfunction triggers potent immunogenic cell death (ICD) with robust damage-associated molecular patterns (DAMPs) release. In situ immunohistochemical analyses confirm that this RMOCZ-induced ICD profoundly remodels the immunosuppressive\u00a0microenvironment, promoting CD86+ antigen-presenting cell maturation and enhancing intratumoral infiltration of CD3+ and CD8+ T cells. In vivo, RMOCZ demonstrates substantial melanoma regression with negligible systemic toxicity, providing a promising strategy for treating apoptosis-resistant refractory malignancies."

In the context of diagnosis, nanoparticle-based molecular imaging probes have been shown to enhance detection sensitivity and specificity. These probes include superparamagnetic iron oxide, which is utilized in magnetic resonance imaging, and near-infrared fluorescent nanomicelles. Additionally, nanostructured liquid biopsy systems have demonstrated the capability to capture circulating tumor cells, exosomes, and circulating tumor DNA with high sensitivity, facilitating non-invasive genotyping and treatment monitoring.

These delivery mechanisms are equipped with TME-responsive release mechanisms (eg, pH, enzyme, redox) that enable the spatiotemporal control of drug release. Nanotechnology offers multi-level strategies to overcome multidrug resistance in castration-resistant prostate cancer, including PROTAC-mediated protein degradation, ferroptosis induction, and synergistic chemo-immunotherapy. Multifunctional theranostic nanoplatforms integrating imaging and therapy enable real-time efficacy assessment and personalized treatment adaptation. Emerging green synthesis approaches that utilize agricultural byproducts and bio-inspired platforms (eg, cell membrane-coated nanoparticles) present sustainable and biocompatible alternatives.

The JAK2-STAT3 signaling pathway serves as a critical regulator of bone remodeling, but its chronic activation contributes to pathological bone metabolism in osteoporosis. Understanding the precise regulation of this pathway is essential for developing novel therapies. Our review reveals that specific miRNAs directly target components of the JAK2-STAT3 pathway (e.g. JAK2, STAT3, SOCS) to fine-tune osteoblast and osteoclast activity. This regulatory network is further expanded by lncRNAs and circRNAs, which act as competitive endogenous RNAs (ceRNAs) or \"molecular sponges\" to sequester miRNAs, thereby indirectly modulating JAK2-STAT3 signaling. This multi-tiered ncRNA network influences key processes such as osteogenic differentiation, inflammatory response and mitochondrial redox homeostasis, ultimately determining bone metabolic balance. The ncRNA network represents a promising therapeutic target for bone-related and metabolic diseases, especially osteoporosis, through its precise control over the JAK2-STAT3 pathway. Targeting these ncRNAs, potentially via engineered exosomes or biomaterial-based delivery systems, offers a novel and different strategy for restoring bone homeostasis, paving the way for future precision medicine in bone metabolic diseases."

In this study, pH-sensitive, core-shell hydrogel microcapsules were designed and fabricated using a BUCHI B-390 microsphere preparation device via electrostatic interactions and hydrogen bonds. Olsalazine sodium was encapsulated in the microcapsules, allowing for pH-responsive drug release in colon tissue for UC treatment in mice. XRD studies demonstrated the amorphous state of the drug in the formulation. The preparation of SCO microcapsules was optimized based on the drug encapsulation efficiency and the drug loading capacity, with the S2C1O microcapsule having the highest drug encapsulation efficiency (59.2%) and drug loading capacity (21.3%), and the production yield was approximately 62.5%.

Conventional treatments, including immunotherapies and targeted inhibitors, face three main challenges: tumor heterogeneity, drug resistance, and systemic toxicity. Nucleic acid therapeutics (NATs) encompass a diverse array of DNA- and RNA-based tools, including small interfering RNA (siRNA), microRNA (miRNA), messenger RNA (mRNA), antisense oligonucleotides (ASOs), and clustered regularly interspaced short palindromic repeats (CRISPR)-associated (Cas) systems. These tools are central to developing precision oncology approaches that operate through direct gene regulation, mutation correction, and immune system reprogramming. The clinical application of NATs currently faces three main obstacles, which include their vulnerability to enzymatic degradation, their limited ability to penetrate tissues, and their tendency to cause off-target effects. The field has progressed through the implementation of nanoformulation techniques, which utilize lipid-based polymeric and metallic carriers together with exosomes and DNA origami, and hybrid nanostructures as new platforms to enhance the stability of drugs and their cellular absorption and targeted delivery to tumors. The scientists developed functionalized nanocarriers by combining targeting ligands with materials that could respond to specific environmental changes, which allowed them to manage drug distribution and release patterns throughout the tumor microenvironment. This review focuses on establishing a direct connection between nucleic acid design and nanotechnology through an analysis of mechanistic details and progress in preclinical and clinical research, and the difficulties encountered during the progress to practical applications. The research demonstrates how artificial intelligence and bioinspired nanocarriers and multi-omics data integration create new opportunities for developing personalized adaptive nanogenetic treatment methods, which will treat lung cancer.

Herein, the surface-engineered exosomal nanoplatform for targeted glioma therapy is functionalized glioblastoma-derived exosomes with the epidermal growth factor receptor (EGFR)-targeting GE11 peptide and loading them with peonidin (PN), a naturally occurring anthocyanin with anticancer potential. The engineered Exo-GE11/PN nanoparticles exhibited favorable physicochemical characteristics, including nanoscale size distribution, high encapsulation efficiency, colloidal stability, and preserved exosome morphology. GE11 functionalization significantly enhanced cellular uptake in EGFR-overexpressing glioma cells, facilitating efficient intracellular delivery of PN. In vitro studies demonstrated that Exo-GE11/PN effectively suppressed glioma cell proliferation, migration, and invasion while promoting apoptotic cell death. Mechanistic investigations revealed that the formulation attenuated EMT through downregulation of SNAI1 and modulation of the PI3K/Akt/NF-\u03baB signaling pathway, accompanied by restoration of epithelial markers and suppression of mesenchymal markers. Furthermore, Exo-GE11/PN significantly reduced tumor growth and improved survival in glioma-bearing mice without inducing clear systemic toxicity, confirming its biocompatibility and therapeutic efficacy. Collectively, these findings highlight the importance of exosome surface engineering for targeted drug delivery and demonstrate that GE11-functionalized exosomes serve as an effective biointerface-mediated carrier for peonidin.

Publications available from database inception through [Month Year] were screened using combinations of keywords including \"exosomes,\" \"extracellular vesicles,\" \"neurological disorders,\" \"brain-targeted delivery,\" \"exosome engineering,\" \"drug delivery,\" and \"clinical trials.\" Additional relevant articles were identified through manual searches of reference lists from selected studies and recent reviews. Exosomes are tiny natural particles released by cells that act as messengers, carrying proteins and genetic material between cells. Scientists are increasingly studying these particles because they may help deliver medicines to the brain and spinal cord, where many treatments struggle to reach due to protective barriers. This review explains how exosomes are formed, how they can be modified to carry drugs or therapeutic molecules, and how they may help treat diseases affecting the nervous system, including Alzheimer\u2019s disease, Parkinson\u2019s disease, stroke, multiple sclerosis, spinal cord injury, and certain neuropsychiatric disorders.We also discuss the advantages of exosomes compared with conventional drug delivery systems and summarize recent advances in engineering strategies that improve their targeting abilities. Although laboratory studies have produced encouraging results, many challenges remain before exosome-based therapies can become routine treatments. These include difficulties related to large-scale production, quality control, safety, and ensuring that exosomes reach the desired tissues without causing unwanted effects.In addition, this review highlights current clinical studies and discusses the steps needed to translate these discoveries into real-world therapies. Overall, exosomes represent an exciting and rapidly evolving area of research that may contribute to the development of safer and more effective treatments for neurological disorders in the future."

While metabolites within the metastatic niche are increasingly recognized as determinants of organotropic metastasis, the role of exosome-mediated metabolite transfer in tumor-lymphatic endothelial cell (LEC) crosstalk remains largely unexplored. Here, we demonstrate that oleic acid (OA) is significantly enriched in both CC lymph node metastases and the peritumoral lymphatic microenvironment. Exosomes derived from highly metastatic CC cells actively package OA in a manner dependent on stearoyl-CoA desaturase (SCD), the rate-limiting enzyme of de novo fatty acid synthesis. Upon internalization by LECs, exosomal OA triggers the AKT/mTOR signaling axis, eliciting robust LEC proliferation and endothelial-to-mesenchymal transition (EndMT), thereby fostering lymphangiogenesis and nodal colonization. Knockdown of SCD abolishes these pro-lymphangiogenic effects, a deficit fully reversed by the reconstitution of OA-loaded exosomes. In vivo, exosomes from SCD-silenced cells exhibit a severely compromised capacity to drive primary tumor growth, intratumoral lymphangiogenesis, and lymph node metastasis (LNM). Notably, free OA administration exerts substantially weaker effects than its exosomal counterpart, underscoring the superior efficiency of exosome-mediated metabolite trafficking. Clinically, FASN and SCD expression are significantly upregulated in lymph node-positive specimens and positively correlate with lymphatic vessel density and p-AKT levels. Furthermore, circulating exosomal OA levels are significantly elevated in patients with nodal involvement, suggesting its potential as a non-invasive diagnostic biomarker. Collectively, our findings establish a paradigm wherein tumor-derived exosomes function as specialized vehicles for intercellular OA transfer, activating the AKT/mTOR pathway to license lymphangiogenic reprogramming. This work identifies exosomal metabolite shuttling as a central node in tumor-lymphatic communication and proposes targeting OA synthesis or exosomal delivery as a promising therapeutic strategy against CC metastasis."

Luteolin (LUT) is a poorly water-soluble natural anti-angiogenic agent. To address this limitation, we develop an ion- and pH-responsive in situ gel system (LUT-NLC-ISG) by incorporating LUT-loaded nanostructured lipid carriers (LUT-NLC) into a gellan gum/Carbopol matrix, aiming to enhance ocular bioavailability and therapeutic efficacy against CNV.

Protein-based nanocarriers, such as the heavy chain of human ferritin (FTH1), facilitate transferrin receptor-mediated transport across the blood-brain barrier. Here, we present multifunctional FTH1 nanocages as a unified nanoplatform for dual-drug chemotherapy and molecular imaging. The nanocages achieve > 98\u202f% gallium-68 labeling efficiency and enable pH-responsive release of doxorubicin and paclitaxel. In isocitrate dehydrogenase (IDH)-wildtype and IDH-mutant tumor models in ovo, FTH1 nanocages exhibit robust intracerebral distribution, tumor accumulation, and enhanced therapeutic efficacy. Dual-drug nanocages significantly reduce tumor growth (p\u202f<\u202f0.001), with a stronger effect in the IDH-mutant model (p\u202f<\u202f0.001), and improve embryo survival. Kinomic profiling reveals broad suppression of AGC and CMGC kinase families, consistent with attenuation of pro-survival and cell-cycle signaling, particularly in IDH-mutant models. These findings suggest treatment-associated kinase network adaptation linked to the IDH status of the models, consistent with increased therapeutic vulnerability, and support further evaluation of FTH1 nanocages as a platform for improved glioma treatment."

A key approach involves reprogramming tumor-associated macrophages (TAMs) from a protumorigenic M2 phenotype to an antitumorigenic M1 state. However, elevated lactate concentration in the TME not only sustains the M2 phenotype but also impairs therapeutic efficacy. To address this challenge, we developed an in situ injectable carboxymethyl chitosan/oxidized sodium alginate (CMCS/OSA) hydrogel with pH-responsive release properties, coloaded with another nanosized active polysaccharide \u03b2-glucan and a lactate-depleting agent lactate oxidase (LOX). Under the acidic conditions of the TME, Schiff base bonds within the hydrogel matrix dissociate, triggering the controlled release of \u03b2-glucan nanoparticles and LOX. The \u03b2-glucan nanoparticles specifically target TAMs via the dendritic cell-associated C-type lectin 1 (Dectin 1) receptor, facilitating their phenotypic conversion from M2 to M1. Simultaneously, the released LOX continuously degrades lactate, preventing the reversion of TAMs back to the M2 phenotype. Collectively, our results demonstrated that this nanocomposite polysaccharide hydrogel system effectively promoted and maintained TAM polarization toward the M1 phenotype through the synergistic effects of immune modulation and metabolic regulation, ultimately enhancing the efficacy of tumor immunotherapy."

This study aimed to enhance the sustained release, targeting, and efficacy of AMC via developing an intratumoral, in situ pH-responsive AMC-loaded novasome (IPANF) hydrogel. The optimal AMC-novasome was tailored using Design-Expert\u00ae software and subsequently incorporated into a chitosan/glyceryl monooleate mixture to develop IPANF. The in vivo anti-tumour efficacy and safety profile of the IPANF were evaluated using an Ehrlich ascites carcinoma model. Within 24\u2009h, the IPANF formulation exhibited a significantly sustained drug release by 65.31% compared to the free AMC suspension. The intratumoral IPANF resulted in a profound 96.08% reduction in tumour volume, a 70.46% recovery in body weight, and a suppression of the CA 15-3 and CA 27-29 levels by 92.66% and 91.23%, respectively. Notably, a 100% survival rate was observed in the intratumoral IPANF group. Histopathological assessments firmly validated the superior therapeutic efficacy of the intratumoral IPANF hydrogel. Furthermore, the intratumoral IPANF formulation demonstrated an excellent safety profile.

However, there is a lack of systematic bibliometric analysis. Therefore, this study employed bibliometric methods to comprehensively review the research trends and hotspots in this field. A comprehensive search was conducted using the Web of Science Core Collection (WoSCC) and Scopus databases for English-language literature published between January 1, 2010, and August 1, 2025. A multidimensional visual analysis of nations, institutions, authors, journals, references, and keywords was performed on the 508 included articles utilizing bibliometric tools VOSviewer, CiteSpace, and Bibliometrix. The number of publications in this field shows an upward trend. From 2010 to 2016, it was in the initial growth stage; from 2017 to 2021, it entered a period of steady growth. After 2022, research activities increased significantly and reached a peak in 2025 (n=131). Frontiers in Immunology (n=25) had the highest number of publications, while Nature Nanotechnology (1,299) had the highest co-citation frequency. Wang Yi-Ching (n=5, H-index =4) and Yang Bo (n=4, H-index =4) are the core authors representing the development of this discipline. China (n=370) has the largest number of publications, and representative institutions include Fudan University (n=19), Chinese Academy of Medical Sciences (n=15), and Shanghai Jiao Tong University (n=14). The USA (94.65) demonstrates the most significant academic influence. Research hotspots have gradually shifted from the correlation between the early macrophage polarization phenotype and the pathological characteristics of lung cancer to molecular mechanisms such as signaling pathways, metabolic reprogramming, and exosomes, and have further expanded to the directions of nanoparticle targeted delivery and clinical translation of immune checkpoint inhibitors. The research in this field has advanced from phenotypic description to mechanism integration and translational research, with nano-intervention and immune regulation being the cutting-edge directions. In the future, attention should be focused on the clinical translation pathways of personalized regulation strategies."

As principal mediators of intercellular communication within the tumor microenvironment, secretory autophagosomes (SAPs) propel breast cancer progression and metastasis by modulating the establishment of the pre-metastatic niche, thereby positioning them as highly promising biomarkers for breast cancer. However, the paucity of accurate and simplified quantitative tools has impeded the direct detection of circulating SAPs. This study presents a sensing platform that couples nanozyme cascade catalysis with a covalent organic frameworks (COFs)-derived nanohydrogel (CGNH) for precisely assessing trace-level SAPs. The AuNBP@PtPd-MoS2 nanozyme, via its stereoconfiguration and trimetallic synergy, recapitulates the dual enzyme-mimicking activities of GOx/CAT. Hence, it enables self-sustained interfacial charge transfer. As a signal probe, it efficiently accelerates self-cascade catalysis and electrochemical mass transfer. Additionally, CGNH creates an ideal interface for SAPs enrichment and cascade catalysis, featuring a hierarchical pore structure, a hybrid conductive network, and suitable biocompatibility. With self-assembled antifouling peptide nanoparticles (APNP) as a shielding barrier, the platform reliably detects SAPs in intricate biological matrices verified using cellular, murine and clinical specimens. Compared with conventional biomarkers, SAPs produce more informative readouts on disease progression. This electrochemical platform differentiates between benign and malignant breast diseases and healthy controls with high diagnostic accuracy (AUC\u202f=\u202f0.962), especially for gray-zone differentiation and metastasis forecasting. This study offers new avenues for SAPs-based liquid biopsy to identify signs of breast cancer metastasis and is expected to become a reliable non-invasive tool for personalized breast cancer management."

Nevertheless, its therapeutic efficacy remains constrained by the hostile tumor microenvironment (TME), typified by acidity and an immunosuppressive milieu. Here, multifunctional microspheres (RC6CaAlgMS) were developed to neutralize the acidic TME and relieve immunosuppression. The uniform-sized calcium alginate microspheres were fabricated using microfluidic technology, incorporating pH-responsive CaCO3 nanocarriers to efficiently encapsulate R848 and C6-ceramide (C6). Their physicochemical properties were characterized, and the embolization efficiency was validated using decellularized liver and rabbit kidney models. Furthermore, their antitumor activities and mechanism were evaluated in both in vitro and in vivo. R848 and C6 were efficiently encapsulated into RC6CaAlgMS, where they acted synergistically to reprogram tumor-associated macrophages (TAMs) toward an M1-like phenotype and to enhance both exosome secretion and exosome-mediated antigen cross-presentation. RC6CaAlgMS produced uniform vascular embolization and efficiently occluded the renal arterial branches. In vitro studies demonstrated that RC6CaAlgMS synergized with DOX-based chemotherapy to suppress the growth of murine HCC by neutralizing acidic TME and remodeling the immune landscape. When combined with PD-L1 blockade therapy, DOX-loaded RC6CaAlgMS effectively inhibited both primary and distant tumors, eliciting an abscopal-like effect driven by enhanced antigen dissemination and T-cell priming. In an orthotopic rat TACE model, the combination of DOX-loaded RC6CaAlgMS with PD-L1 blockade achieved complete tumor eradication. Collectively, this study establishes a multifunctional microsphere platform that effectively remodels and overcomes the post-TACE immunosuppressive TME, offering a potent strategy for integrating embolization with immunotherapy in HCC."

Hollow mesoporous manganese silicate nanoparticles were engineered as Mn2\u207a-releasing nanocarriers for loading a STING agonist (Sa) diABZI, followed by coating with anti-PD-L1 antibody-functionalized NSCLC tumor cell membranes. The resulting Sa@HMMSN@PM exhibited pH-responsive Sa release, preserved PD-L1 blocking activity, and enhanced tumor-cell-selective uptake.

This study evaluates the therapeutic potential of exosomes derived from induced pluripotent stem cell-derived mesenchymal stem cells (iPSCMSC-exo) versus umbilical cord-derived MSC exosomes (hUCMSC-exo) for POI intervention.

A series of pH-responsive hydrogels were fabricated, leading to sustained EV release regulated by viscoelastic properties. The pH of these hydrogels decreased from 9 to 7 during incubation, which altered hydrogel viscoelasticity, thereby modulating EV release kinetics. In addition, EV-loaded hydrogels regulated key hSCO patterning markers such as DBX1 and ISL1. Furthermore, these EVs in hydrogels can cross a modeled blood-spinal cord barrier and provide cross-barrier capability for delivery. Taken together, the organoid-secreted EVs in viscoelastic HA hydrogels can be released at a controlled rate and have potential to regulate spinal cord organoid patterning. This study advances our knowledge of regulating intercellular communication and developing EV-based therapies for treating neurological disorders such as spinal cord injury."

While monomers or compound formulas of TCM can ameliorate such injury through multi-target and multi-pathway mechanisms, their clinical efficacy is hampered by poor targeting and low bioavailability. In recent years, biomimetic membrane preparations, primarily biomimetic cell membrane preparations and exosomes, have emerged as a novel therapeutic strategy for myocardial ischemic injury. Owing to their natural bioactivity, easy engineerability, and other characteristics, they enable the targeted delivery of TCM components to ischemic lesions and facilitate their transport across biological barriers. This review focused on the core pathological mechanisms of myocardial ischemic injury, elaborated on the types and unique functions of biomimetic cell membrane preparations and exosomes, and provided a critical analysis of the design strategies and action mechanisms of such biomimetic cell membrane preparations. Furthermore, it discussed the adaptability of different administration routes and highlighted the potential and the existing challenges of natural biomimetic membrane preparations. The aim of this study is to offer insights for the design, research, and development of biomimetic preparations for myocardial ischemic injury."

Exosomes, as promising endogenous nanocarriers, have emerged as a powerful tool for the prevention and treatment of CVDs. In particular, advanced functionalization strategies have largely enhanced exosomal therapeutic efficacy in\u00a0vivo. Notably, Traditional Chinese Medicine (TCM) and its bioactive components exert profound regulatory effects on exosomes. In this review, we systematically summarize exosome-based therapeutic strategies for CVDs, along with state-of-art functionalization approaches to optimize exosomal cargo loading and targeted delivery. We further provide a comprehensive overview of TCM-mediated exosomal regulation. We found that TCM and TCM-derived chemicals can optimize exosomal cargo loading, especially the loading of microRNAs (miRNAs) and bioactive chemicals. More importantly, TCM and chemicals can promote exosomal secretion, which provides new avenues for exosomal-scale production. Besides, there are synergistic effects between exosomes and TCM when co-administered. Collectively, exosome-based systems hold great promise for CVD therapy, and TCM provides novel strategies for exosomal functionalization, which substantially enhances exosomal-mediated therapeutic efficacy for CVDs."

To deliver drugs specifically to cancer cells that overexpress CD44, this study developed hyaluronic acid (HA)-functionalized dextran (DEX) polymeric nanoparticles (ETP-DEX-HA-NPs). Optimised nanoparticles (174.7\u2009\u00b1\u20093.2\u2009nm, -12.83\u2009\u00b1\u20091.1\u2009mV) demonstrated significant entrapment efficiency (62.75\u2009\u00b1\u20092.32%) and drug loading (55.64\u2009\u00b1\u20093.86%), with partial amorphization validated by FTIR, XRD, Raman, NMR and DSC analyses.

"abstract_text": "ID: 42522799\nTitle: Oral Squamous Cell Carcinoma: A New Era in Molecular Mechanisms and Emerging Targeted Therapies.\nAbstract: Oral squamous cell carcinoma (OSCC), the most common oral cancer, presents a clinical challenge due to its complex tumor microenvironment (TME), dysregulated pathways, and poor prognosis. Current methods of diagnosing OSCC use liquid biopsy technologies (ctDNA/microRNAs/exosomes) instead of relying solely on traditional methods such as open surgical biopsy. Liquid biopsy technologies provide non-invasive ways to detect and monitor OSCC in early stages, compared with traditional open surgical biopsy methods. Treatment of OSCC currently relies on chemotherapeutics (cisplatin/5-FU), radiotherapy, and targeted agents (cetuximab). However, resistance is acquired due to TME remodelling (tumor microenvironment) and/or due to epithelial-mesenchymal transition (EMT) through processes such as ABC transporter efflux. This review elucidates key molecular mechanisms, including PD-L1-mediated immune evasion, PI3K/AKT/mTOR hyperactivation, EGFR overexpression, and NF-\u03baB-driven inflammation, which promote proliferation, metastasis, and therapy resistance. One area of study involves the use of nanotechnology to convert phytocompounds (medicinal plants) into therapeutic agents by embedding phytocompounds into nanoparticles created using green synthesis techniques. EPR (Enhanced Permeability and Retention), ligand functionalization for OSCC targeting, improved bioavailability, and reduced toxicity are all advantages that the aforementioned systems provide, offering an opportunity to synergistically develop new therapies with chemotherapeutics for overcoming resistance. While numerous preclinical studies demonstrate that these newly developed therapies show increased efficacy compared with current therapy options, further work is needed in areas such as standardization, scaling, and clinical translation. As such, the importance of developing pathway-informed diagnostic tests and developing therapies that exploit pathway-specific activity with phytocompounds is emphasized. In addition, large-scale studies should be considered to evaluate the effectiveness of a pathway-informed approach in assessing and differentiating OSCC and personalized therapy strategies, to improve OSCC survival outcomes."

This review aims to present an integrated model of lymphatic and hematogenous dissemination that provides a unified framework for understanding metastatic progression. Methods: The published literature on lymphatic biology, microvascular physiology, tumor immunology, and cancer metastasis was critically reviewed and integrated to develop a comprehensive anatomical and physiological model of cancer dissemination. Results: The proposed model identifies lymphatic dissemination as the predominant metastatic route in many solid tumors. Cancer cells enter structurally permissive initial lymphatic capillaries and are transported to the sentinel lymph node (SLN), where interactions with the tumor microenvironment may eliminate disseminated cells, maintain dormancy, or facilitate immune escape and further dissemination. Cancer cells that survive within or escape beyond the SLN subsequently travel through collecting lymphatics and the thoracic or right lymphatic duct to enter the systemic venous circulation. Following cardiopulmonary transit, surviving cells may be redistributed through the systemic arterial circulation to distant organs. A secondary pathway involves direct hematogenous intravasation through post-capillary venules, where reduced shear stress, increased endothelial permeability, and permissive endothelial biology facilitate entry into the venous circulation. Thus, lymphatic and direct venular pathways ultimately converge in the venous circulation before systemic arterial dissemination. Conclusions: This unified model integrates lymphatic and hematogenous dissemination into a coherent anatomical and physiological framework. By emphasizing the SLN as an early immunologic checkpoint and the arterial circulation as the final distribution network for disseminated cancer cells, this review provides a conceptual basis for understanding metastatic patterns and identifying biomarkers and therapeutic vulnerabilities."

Nevertheless, despite considerable progress in elucidating its molecular background, early diagnosis and accurate stratification of disease progression remain challenging when relying on conventional clinical biomarkers such as albuminuria and estimated glomerular filtration rate (eGFR). Growing evidence indicates that DKD is driven by interconnected pathogenic mechanisms, including chronic hyperglycemia, activation of the protein kinase C (PKC) signaling pathway, renin-angiotensin-aldosterone system (RAAS) dysregulation, oxidative stress, inflammatory cascades, and immune system activation involving Toll-like receptors (TLR) and the NLRP3 inflammasome. These processes collectively contribute to endothelial dysfunction, podocyte injury, extracellular matrix accumulation, and progressive renal fibrosis. Exosomes and their molecular cargo, particularly miRNAs, have emerged as promising regulators and non-invasive biomarkers reflecting ongoing renal injury. Urinary exosomal microRNAs (uEV-miRNAs) are of interest due to their stability in biological fluids and their direct origin from nephron segments, enabling real-time reflection of renal pathophysiology. Accumulating studies suggest that differentially expressed microRNAs (miRNAs), including miR-21-5p, miR-30a-5p, miR-192-5p, and miR-142-3p, are closely associated with key pathways in DN. However, their clinical translation remains limited by methodological heterogeneity, the lack of standardized isolation protocols, and insufficient validation in large longitudinal cohorts. This review navigates the current landscape of knowledge on the molecular mechanisms underlying DKD and examines the emerging role of uEV-miRNAs as diagnostic biomarkers. Altogether, uEV-miRNAs offer a promising avenue for improving early detection, risk stratification, and disease monitoring in DKD."

The hydrogel was synthesized using polyethylene glycol (PEG), 2-hydroxyethyl methacrylate (HEMA), acrylic acid (AA), with N,N'-methylene bisacrylamide (MBA) as a cross-linker and potassium persulfate (KPS) as an initiator. The hydrogel's structural integrity and formation were confirmed through Fourier-transform infrared spectroscopy (FTIR), scanning electron microscopy (SEM), differential scanning calorimetry (DSC), and swelling studies. It is noteworthy that the hydrogel exhibits a different pH-dependent swelling behaviour, which expands under alkaline conditions and maintains its compact structure under acidic conditions. The content of acrylic acid contributed to the high-water retention and the swelling profile indicated that the product was suitable for the specific release of the drug at the site. The in-vitro release of rabeprazole sodium at acidic pH is very low, thus protecting rabeprazole sodium from premature degradation in the stomach; however, controlled release of rabeprazole sodium was achieved at intestinal pH via a non-Fickian diffusion mechanism (Korsmeyer-Peppas n = 0.40-0.62, Higuchi R\u00b2 = 0.991-0.996) over 12 h. Moreover, in-vivo acute toxicity studies indicated that the hydrogel is highly biocompatible, suggesting it is safe for use in future therapeutic applications. Overall, the PEG (HEMA-co-AA) hydrogel represents a versatile vehicle for the controlled and local administration of acid-labile pharmaceuticals, thereby promoting increased therapeutic efficacy."

While mesenchymal stem cell-derived exosomes (MSC-Exos) hold potential for liver regeneration, their therapeutic efficacy is often limited by poor target specificity and rapid clearance. Here, we developed mannose receptor-targeting MSC-Exos (Man-Exos) by incorporating DSPE-PEG-Mannose via a post-insertion method to enhance LSEC-specific delivery. The physicochemical stability and targeting efficiency of Man-Exos were evaluated both in vitro and in vivo. Man-Exos exhibited high stability in various conditions and showed significantly enhanced binding affinity to LSECs compared to non-targeted exosomes. Notably, in a co-culture system of LSECs and macrophages, Man-Exos demonstrated superior selectivity for LSECs. In vivo biodistribution studies further confirmed that Man-Exos predominantly accumulated in the liver, specifically colocalizing with LSECs for up to 48\u2009h. Our findings suggest that Man-Exos can serve as a highly efficient and stable delivery platform for LSEC-targeted therapy, providing a promising strategy for enhancing the translational potential of exosome-based regenerative medicine in liver fibrosis."

The core mechanisms underlying these diseases include impaired T-cell and B-cell immune tolerance, abnormal cytokine production, and aberrant activation of related signaling pathways. Conventional treatments primarily focus on suppressing immune responses, but their efficacy remains limited and they are often associated with substantial side effects. Nanomedicine leverages nanoscale materials to enable precise diagnosis and targeted therapy. Nanocarriers can penetrate biological barriers, enhance cellular uptake, and prolong circulation time in vivo, demonstrating considerable potential for drug delivery. Common nanoscale drug delivery platforms include nanoparticles, polymeric micelles, liposomes, dendrimers, mesoporous materials, hydrogels, and exosomes. Each carrier type possesses distinct characteristics in terms of drug-loading capacity, stability, responsiveness, and biocompatibility, thereby enabling targeted delivery and controlled release. This review summarizes recent advances in nano-delivery technologies for three representative chronic autoimmune diseases: diabetes mellitus (DM), inflammatory bowel disease (IBD), and rheumatoid arthritis (RA). Nano-delivery systems can improve therapeutic outcomes by optimizing drug delivery, targeting complications, and modulating the pathological microenvironment. They enhance drug bioavailability, reduce off-target and systemic adverse effects, and provide novel strategies for the precise and efficient treatment of chronic autoimmune diseases."

Approximately 10-20% of gastric cancers overexpress HER2, conferring aggressive tumor characteristics and poor survival, yet resistance to trastuzumab-based targeted therapy and limited intratumoral antibody penetration continue to restrict clinical outcomes. This study evaluated HER2-targeted exosomes as a delivery platform. Exosomes were engineered to express the p51 peptide, a high-affinity HER2-binding ligand, and loaded with 17-dimethylaminoethylamino-17-demethoxygeldanamycin (17-DMAG), a potent HSP90 inhibitor. The cellular uptake and antitumor efficacy of p51-Exo17-DMAG were assessed in vitro using NCI-N87 and AGS cells and in vivo using a mouse xenograft model. p51-modified exosomes exhibited superior HER2 specific uptake. Treatment with p51-Exo17-DMAG significantly increased apoptosis, as demonstrated by elevated PARP and caspase3 cleavage, and downregulated oncogenic signaling molecules, including p-AKT, CDK2, VEGF, and c-Myc. Furthermore, p51-Exo17-DMAG increased the number of TUNEL-positive cells. In the NCI-N87 xenograft model, systemic administration of p51-Exo17-DMAG significantly inhibited tumor growth without toxicity or histological damage to major organs.

This recalcitrance stems largely from loss-of-function mutations within the low-density lipoprotein receptor (LDLR) gene, which severely undermine the efficacy of standard therapeutic regimens. Here, we report a bioinspired \"targeting and blockade\" strategy for the efficient delivery of functional Ldlr mRNA to hepatocytes. This approach is realized through a rationally designed platform, Szd\u00a0+\u00a0AP@ExoE-Ldlr, which integrates APOA1-functionalized exosomes for hepatocyte-targeted delivery with a preemptive macrophage blockade using the clinical ultrasound contrast agent Sonazoid (Szd). The APOA1 modification confers specific recognition by the scavenger receptor class B type 1 on hepatocytes, while the pre-saturation of Kupffer cells with Szd significantly mitigates nonspecific clearance by the mononuclear phagocyte system (MPS). In a HoFH murine model, this synergistic strategy markedly enhanced the accumulation of exosomes in hepatocytes and achieved robust restoration of hepatic LDLR expression. Consequently, it elicited a profound correction of the atherogenic lipid profile and substantially attenuated the progression of atherosclerosis. A comprehensive biosafety evaluation confirmed the excellent biocompatibility of this platform. Our work provides a promising and broadly applicable solution for the treatment of liver-related genetic disorders by simultaneously overcoming the critical barriers of targeted delivery and MPS evasion."

Probiotics and postbiotics represent promising preclinical candidates to alleviate these unmet clinical bottlenecks. Bacterial extracellular vesicles (BEVs) are naturally secreted bacterial nanovesicles carrying abundant bioactive cargos, whose bioactivity and safety are highly strain-dependent. Probiotics-derived BEVs can remodel gut homeostasis, repair epithelial barriers, and regulate mucosal immunity to suppress the inflammatory vicious cycle in IBD, while pathogen-/pathobiont-derived BEVs loaded with lipopolysaccharide and virulence factors exacerbate intestinal inflammation. Native BEVs are restricted by low cargo loading, poor gastrointestinal stability and inadequate colon tropism.

To address these critical challenges, we developed an innovative dual-targeted nanoplatform (Exo-SPIONs-SRF/CGA) that synergistically combines the natural tumour-homing capability of HCC-derived exosomes with the magnetic guidance of superparamagnetic iron oxide nanoparticles (SPIONs) for precision drug targeting.

It is the first organized immune-stromal site exposed to lymph-borne melanoma-derived extracellular vesicles (EVs), soluble mediators, proteins, lipids, and non-coding RNAs (ncRNAs) before and during metastatic seeding.

While T-cell activation is implicated, the role of soluble programmed death-1 (sPD-1), primarily derived from activated T cells, in PF pathogenesis remains elusive. We initially analyzed serum sPD-1 levels in PD patients and employed a mice PF model induced by high-glucose dialysate and lipopolysaccharide (LPS). The functional impact of sPD-1 on the progression of PF was assessed through the administration of a PD-L1 fusion protein, or engineered exosomes designed to adsorb sPD-1. Serum sPD-1 levels were significantly elevated in long-term PD patients and were positively correlated with dialysis duration and markers of fibrosis, but inversely correlating with peritoneal function. In mice, exogenous sPD-1 exacerbated PF, whereas blockade with a PD-L1 fusion protein or sPD-1-adsorbing engineered exosomes markedly attenuated fibrosis, reduced T-cell infiltration, and preserved peritoneal function. Mechanistically, sPD-1 bound to PD-L1 on PMCs, triggering clathrin-mediated endocytosis. This interaction diverted PD-L1 from the lysosomal degradation pathway towards the Rab11-positive recycling endosome pathway, resulting in sustained upregulation of surface PD-L1 expression. This aberrant PD-L1 recycling activated pro-fibrotic signaling, culminating in mesothelial-to-mesenchymal transition (MMT). sPD-1 is a pivotal mediator linking peritoneal microinflammation to fibrosis by modulating the endocytic fate of PD-L1 in mesothelial cells. Targeting sPD-1, particularly using engineered exosomes or a PD-L1 fusion protein, represents a promising therapeutic strategy for preventing and treating peritoneal fibrosis."

This recalcitrance stems largely from loss-of-function mutations within the low-density lipoprotein receptor (LDLR) gene, which severely undermine the efficacy of standard therapeutic regimens. Here, we report a bioinspired \"targeting and blockade\" strategy for the efficient delivery of functional Ldlr mRNA to hepatocytes. This approach is realized through a rationally designed platform, Szd\u00a0+\u00a0AP@ExoE-Ldlr, which integrates APOA1-functionalized exosomes for hepatocyte-targeted delivery with a preemptive macrophage blockade using the clinical ultrasound contrast agent Sonazoid (Szd). The APOA1 modification confers specific recognition by the scavenger receptor class B type 1 on hepatocytes, while the pre-saturation of Kupffer cells with Szd significantly mitigates nonspecific clearance by the mononuclear phagocyte system (MPS). In a HoFH murine model, this synergistic strategy markedly enhanced the accumulation of exosomes in hepatocytes and achieved robust restoration of hepatic LDLR expression. Consequently, it elicited a profound correction of the atherogenic lipid profile and substantially attenuated the progression of atherosclerosis. A comprehensive biosafety evaluation confirmed the excellent biocompatibility of this platform. Our work provides a promising and broadly applicable solution for the treatment of liver-related genetic disorders by simultaneously overcoming the critical barriers of targeted delivery and MPS evasion."

Cuproptosis has emerged as a promising mechanism by which to inhibit tumors because copper homeostasis disorders frequently occur in various malignancies. The combination of disulfiram (DSF) and copper ions (DSF/Cu) has been shown to have significant antitumor effects. This study utilized DSF/Cu to investigate the mechanism underlying cuproptosis in GC cells. GC cells were treated with DSF/Cu and protein sequencing was performed to screen for differentially expressed genes. The mechanism by which overexpressed FDX1 regulates cuproptosis and WDR43 expression was determined. Subsequently, how to improve the efficacy of DSF/Cu in the treatment of GC was studied in a mouse model of GC. DSF/Cu had a good therapeutic effect on promoting cuproptosis in GC cells. Protein sequencing revealed WDR43 as a downstream gene of FDX1. Increasing the expression of FDX1 enhanced the sensitivity of GC cells to copper treatment and inhibited the expression of WDR43, thereby exerting an antitumor effect. Furthermore, DSF/Cu was loaded into exosomes derived from natural killer (NK) cells to enhance the biological safety and tumor targeting of DSF/Cu and validate the inhibitory effect on GC both in vitro and in vivo. This study showed that DSF/Cu promoted cuproptosis and the expression of FDX1 affected cuproptosis sensitivity of GC. Moreover, the combination of NK cell exosomes with DSF/Cu improved the therapeutic effect of DSF/Cu, which helps to promote the targeted therapy of GC and improve clinical applicability."

Exosomes (Exos) are key mediators of intercellular communication and promising vehicles for targeted therapy. This study aimed to investigate the function and underlying mechanism of exercise-derived exosomes (Exe-Exos) in SCI recovery. Circulating Exos were isolated from rats subjected to a 4-week treadmill Exe regimen and from sedentary controls. A gelatin methacrylate (GelMA) hydrogel microneedles (Hyd MNs) system was developed for the targeted, sustained delivery of these Exos directly to the injury epicenter at the T10 spinal segment in a rat SCI model. Using integrated in vitro and in vivo approaches, we showed that Exe-Exos significantly promoted motor function recovery, attenuated tissue damage, reduced apoptosis, and alleviated both inflammation and oxidative stress (Oxs) after SCI. Small RNA sequencing revealed that miR-151-3p is a key functional cargo that is enriched in Exe-Exos. Gain- and loss-of-function studies revealed that exosomal miR-151-3p exerts its protective effects by directly targeting the mitochondrial membrane protein ROMO1. This targeting led to the coordinated inhibition of the pro-apoptotic JNK/Caspase pathway, suppression of the NF-\u03baB-mediated inflammatory cascade, and activation of the Nrf2/HO-1 antioxidant axis. Collectively, our findings establish Exe-Exos, specifically exosomal miR-151-3p, as an exercise-responsive circulating signaling axis that orchestrates multifaceted protection against secondary injury after SCI, offering an innovative, mechanism-based strategy for neuroregenerative therapy."

In this study, we systematically evaluated the anti-tumor effect of Bi2536, an inhibitor of Polo-like kinase 1 (PLK1), in HGSOC, and clarified its mechanism. Bi2536 inactivates PLK1, leading to the subsequent inactivation of cyclin-dependent kinase 1 (CDK1). This disruption triggers a cascade of antitumor effects, including G2/M phase arrest, induction of mitochondrial apoptosis, and suppression of cell migration and invasion. Furthermore, we identified circadian oscillations in PLK1 expression both in HGSOC cells and in vivo xenograft models. To enhance therapeutic precision and minimize systemic toxicity, we engineered a biomimetic nano-delivery system for Bi2536. This integrated platform combines chemotherapy and chemodynamic therapy (CDT), significantly improving antitumor outcomes. Importantly, synchronizing Bi2536 administration with the circadian peaks of PLK1 expression further augmented its therapeutic efficacy. In summary, our work establishes that the combination of Bi2536 with a biomimetic nano-delivery system, together with its chronotherapeutic administration, constitutes a highly promising and multifaceted strategy for the treatment of HGSOC."

We used SciExplorer, VOSviewer, and Citespace to analyze countries, institutions, authors, keywords, highly cited references, and co-cited references to discuss research hotspots and trends in this field. The research analysis included a total of 959 pieces of literature, with China and the USA leading in the number of papers published and academic influence.

In the context of diagnosis, nanoparticle-based molecular imaging probes have been shown to enhance detection sensitivity and specificity. These probes include superparamagnetic iron oxide, which is utilized in magnetic resonance imaging, and near-infrared fluorescent nanomicelles. Additionally, nanostructured liquid biopsy systems have demonstrated the capability to capture circulating tumor cells, exosomes, and circulating tumor DNA with high sensitivity, facilitating non-invasive genotyping and treatment monitoring. In the field of therapeutics, PSMA-targeted liposomes, polymeric nanoparticles, and inorganic nanocarriers have demonstrated efficacy in enhancing the delivery of chemotherapeutics, gene-editing tools (eg, CRISPR/Cas9, siRNA), and immunomodulators. These delivery mechanisms are equipped with TME-responsive release mechanisms (eg, pH, enzyme, redox) that enable the spatiotemporal control of drug release. Nanotechnology offers multi-level strategies to overcome multidrug resistance in castration-resistant prostate cancer, including PROTAC-mediated protein degradation, ferroptosis induction, and synergistic chemo-immunotherapy. Multifunctional theranostic nanoplatforms integrating imaging and therapy enable real-time efficacy assessment and personalized treatment adaptation. Emerging green synthesis approaches that utilize agricultural byproducts and bio-inspired platforms (eg, cell membrane-coated nanoparticles) present sustainable and biocompatible alternatives. Concurrently, artificial intelligence (AI) holds the potential to expedite the design of nanocarriers. Despite the advancement of several nanomedicines to clinical trials, significant translational barriers persist.

In this study, pH-sensitive, core-shell hydrogel microcapsules were designed and fabricated using a BUCHI B-390 microsphere preparation device via electrostatic interactions and hydrogen bonds. Olsalazine sodium was encapsulated in the microcapsules, allowing for pH-responsive drug release in colon tissue for UC treatment in mice. XRD studies demonstrated the amorphous state of the drug in the formulation. The preparation of SCO microcapsules was optimized based on the drug encapsulation efficiency and the drug loading capacity, with the S2C1O microcapsule having the highest drug encapsulation efficiency (59.2%) and drug loading capacity (21.3%), and the production yield was approximately 62.5%. The degradation experiment results indicated that the alginate/CMCS hydrogel shell has anti-resistant and colon-targeted properties, with minimal drug leakage under acidic conditions (0.1% release at 2 h, pH 1.2) and rapid, controlled release at colonic pH (7.4) (cumulative release of 68.7% at 12 h), protecting the drug from gastric degradation. An in vivo experiment suggested that treatment with these microcapsules in UC mice significantly reduced inflammatory markers (NF-\u03baB p65 was reduced by 18.8% relative to the free drug group) and histological damage in UC models relative to free drug administration. The improved therapeutic efficacy is linked to precise localization in inflamed tissue, reducing systemic exposure and off-target effects. Overall, in vitro and in vivo studies demonstrated that this microcapsule system provides a promising alternative to existing UC drug delivery systems."

Recent developments in the design of amphiphilic chitosan derivatives modified with hydrophobic moieties, including fatty acids, cholesterol, bile acids, and functional ligands, are systematically compiled in this study. Such modifications allow for spontaneous self-assembly into micelles or nanoparticles that can encapsulate various hydrophobic drugs, including doxorubicin, paclitaxel, derivatives of camptothecin, and natural bioactives.

Herein, the surface-engineered exosomal nanoplatform for targeted glioma therapy is functionalized glioblastoma-derived exosomes with the epidermal growth factor receptor (EGFR)-targeting GE11 peptide and loading them with peonidin (PN), a naturally occurring anthocyanin with anticancer potential. The engineered Exo-GE11/PN nanoparticles exhibited favorable physicochemical characteristics, including nanoscale size distribution, high encapsulation efficiency, colloidal stability, and preserved exosome morphology. GE11 functionalization significantly enhanced cellular uptake in EGFR-overexpressing glioma cells, facilitating efficient intracellular delivery of PN. In vitro studies demonstrated that Exo-GE11/PN effectively suppressed glioma cell proliferation, migration, and invasion while promoting apoptotic cell death. Mechanistic investigations revealed that the formulation attenuated EMT through downregulation of SNAI1 and modulation of the PI3K/Akt/NF-\u03baB signaling pathway, accompanied by restoration of epithelial markers and suppression of mesenchymal markers. Furthermore, Exo-GE11/PN significantly reduced tumor growth and improved survival in glioma-bearing mice without inducing clear systemic toxicity, confirming its biocompatibility and therapeutic efficacy.

This review highlights recent advances in exosome biology, cargo-sorting mechanisms, and engineering strategies designed to enhance therapeutic delivery and targeting within the central nervous system. Particular emphasis is placed on the application of engineered exosomes in neurodegenerative diseases, stroke, spinal cord injury, neuropathic pain, and neuroinflammatory disorders. In addition, we discuss how exosomes compare with conventional delivery platforms and critically examine the major barriers limiting their clinical translation, including heterogeneity, scalability, reproducibility, purity, and regulatory standardization. By integrating mechanistic insights with translational perspectives, this review provides a framework for the rational design and future clinical implementation of exosome-based nanomedicines for neurological disorders. Relevant literature was identified through searches of PubMed, Scopus, Web of Science, and Google Scholar. Publications available from database inception through [Month Year] were screened using combinations of keywords including \"exosomes,\" \"extracellular vesicles,\" \"neurological disorders,\" \"brain-targeted delivery,\" \"exosome engineering,\" \"drug delivery,\" and \"clinical trials.\" Additional relevant articles were identified through manual searches of reference lists from selected studies and recent reviews. Exosomes are tiny natural particles released by cells that act as messengers, carrying proteins and genetic material between cells. Scientists are increasingly studying these particles because they may help deliver medicines to the brain and spinal cord, where many treatments struggle to reach due to protective barriers. This review explains how exosomes are formed, how they can be modified to carry drugs or therapeutic molecules, and how they may help treat diseases affecting the nervous system, including Alzheimer\u2019s disease, Parkinson\u2019s disease, stroke, multiple sclerosis, spinal cord injury, and certain neuropsychiatric disorders.We also discuss the advantages of exosomes compared with conventional drug delivery systems and summarize recent advances in engineering strategies that improve their targeting abilities. Although laboratory studies have produced encouraging results, many challenges remain before exosome-based therapies can become routine treatments. These include difficulties related to large-scale production, quality control, safety, and ensuring that exosomes reach the desired tissues without causing unwanted effects.In addition, this review highlights current clinical studies and discusses the steps needed to translate these discoveries into real-world therapies. Overall, exosomes represent an exciting and rapidly evolving area of research that may contribute to the development of safer and more effective treatments for neurological disorders in the future."

While metabolites within the metastatic niche are increasingly recognized as determinants of organotropic metastasis, the role of exosome-mediated metabolite transfer in tumor-lymphatic endothelial cell (LEC) crosstalk remains largely unexplored. Here, we demonstrate that oleic acid (OA) is significantly enriched in both CC lymph node metastases and the peritumoral lymphatic microenvironment. Exosomes derived from highly metastatic CC cells actively package OA in a manner dependent on stearoyl-CoA desaturase (SCD), the rate-limiting enzyme of de novo fatty acid synthesis. Upon internalization by LECs, exosomal OA triggers the AKT/mTOR signaling axis, eliciting robust LEC proliferation and endothelial-to-mesenchymal transition (EndMT), thereby fostering lymphangiogenesis and nodal colonization. Knockdown of SCD abolishes these pro-lymphangiogenic effects, a deficit fully reversed by the reconstitution of OA-loaded exosomes. In vivo, exosomes from SCD-silenced cells exhibit a severely compromised capacity to drive primary tumor growth, intratumoral lymphangiogenesis, and lymph node metastasis (LNM). Notably, free OA administration exerts substantially weaker effects than its exosomal counterpart, underscoring the superior efficiency of exosome-mediated metabolite trafficking. Clinically, FASN and SCD expression are significantly upregulated in lymph node-positive specimens and positively correlate with lymphatic vessel density and p-AKT levels. Furthermore, circulating exosomal OA levels are significantly elevated in patients with nodal involvement, suggesting its potential as a non-invasive diagnostic biomarker. Collectively, our findings establish a paradigm wherein tumor-derived exosomes function as specialized vehicles for intercellular OA transfer, activating the AKT/mTOR pathway to license lymphangiogenic reprogramming. This work identifies exosomal metabolite shuttling as a central node in tumor-lymphatic communication and proposes targeting OA synthesis or exosomal delivery as a promising therapeutic strategy against CC metastasis."

Ocular pharmacokinetics and biodistribution were evaluated in rabbits after a single topical administration. Biocompatibility was assessed via Hen's egg test-chorioallantoic membrane assay (HET-CAM), Draize tests, and cytotoxicity studies. Therapeutic efficacy and mechanism were investigated in a murine model of alkali burn-induced CNV. Results: The optimized LUT-NLC-ISG had a particle size of 25.27 \u00b1 0.23 nm and exhibited a 45-fold viscosity increase upon simulated tear fluid (STF) exposure. In rabbits, LUT-NLC-ISG significantly increased the bioavailability of LUT in ocular tissues compared with LUT-NLC alone, with 2.57-, 1.83-, and 10.59-fold higher area under the concentration-time curve (AUC) in the cornea, conjunctiva, and tears, respectively and exhibited excellent ocular biocompatibility. In the CNV mouse model, 0.1% (w/v) LUT-NLC-ISG effectively inhibited corneal neovascularization, comparable to 0.025% dexamethasone, and downregulated VEGF-A and MMP-9 expression. Conclusions: LUT-NLC-ISG synergistically combines NLC technology and dual-sensitive in situ gelation to significantly improve LUT ocular bioavailability, offering a promising non-invasive candidate for CNV management."

Protein-based nanocarriers, such as the heavy chain of human ferritin (FTH1), facilitate transferrin receptor-mediated transport across the blood-brain barrier. Here, we present multifunctional FTH1 nanocages as a unified nanoplatform for dual-drug chemotherapy and molecular imaging. The nanocages achieve > 98\u202f% gallium-68 labeling efficiency and enable pH-responsive release of doxorubicin and paclitaxel. In isocitrate dehydrogenase (IDH)-wildtype and IDH-mutant tumor models in ovo, FTH1 nanocages exhibit robust intracerebral distribution, tumor accumulation, and enhanced therapeutic efficacy. Dual-drug nanocages significantly reduce tumor growth (p\u202f<\u202f0.001), with a stronger effect in the IDH-mutant model (p\u202f<\u202f0.001), and improve embryo survival. Kinomic profiling reveals broad suppression of AGC and CMGC kinase families, consistent with attenuation of pro-survival and cell-cycle signaling, particularly in IDH-mutant models. These findings suggest treatment-associated kinase network adaptation linked to the IDH status of the models, consistent with increased therapeutic vulnerability, and support further evaluation of FTH1 nanocages as a platform for improved glioma treatment."

A key approach involves reprogramming tumor-associated macrophages (TAMs) from a protumorigenic M2 phenotype to an antitumorigenic M1 state. However, elevated lactate concentration in the TME not only sustains the M2 phenotype but also impairs therapeutic efficacy. To address this challenge, we developed an in situ injectable carboxymethyl chitosan/oxidized sodium alginate (CMCS/OSA) hydrogel with pH-responsive release properties, coloaded with another nanosized active polysaccharide \u03b2-glucan and a lactate-depleting agent lactate oxidase (LOX). Under the acidic conditions of the TME, Schiff base bonds within the hydrogel matrix dissociate, triggering the controlled release of \u03b2-glucan nanoparticles and LOX. The \u03b2-glucan nanoparticles specifically target TAMs via the dendritic cell-associated C-type lectin 1 (Dectin 1) receptor, facilitating their phenotypic conversion from M2 to M1. Simultaneously, the released LOX continuously degrades lactate, preventing the reversion of TAMs back to the M2 phenotype. Collectively, our results demonstrated that this nanocomposite polysaccharide hydrogel system effectively promoted and maintained TAM polarization toward the M1 phenotype through the synergistic effects of immune modulation and metabolic regulation, ultimately enhancing the efficacy of tumor immunotherapy."

This study aimed to enhance the sustained release, targeting, and efficacy of AMC via developing an intratumoral, in situ pH-responsive AMC-loaded novasome (IPANF) hydrogel. The optimal AMC-novasome was tailored using Design-Expert\u00ae software and subsequently incorporated into a chitosan/glyceryl monooleate mixture to develop IPANF. The in vivo anti-tumour efficacy and safety profile of the IPANF were evaluated using an Ehrlich ascites carcinoma model. Within 24\u2009h, the IPANF formulation exhibited a significantly sustained drug release by 65.31% compared to the free AMC suspension. The intratumoral IPANF resulted in a profound 96.08% reduction in tumour volume, a 70.46% recovery in body weight, and a suppression of the CA 15-3 and CA 27-29 levels by 92.66% and 91.23%, respectively.

Nevertheless, its therapeutic efficacy remains constrained by the hostile tumor microenvironment (TME), typified by acidity and an immunosuppressive milieu. Here, multifunctional microspheres (RC6CaAlgMS) were developed to neutralize the acidic TME and relieve immunosuppression. The uniform-sized calcium alginate microspheres were fabricated using microfluidic technology, incorporating pH-responsive CaCO3 nanocarriers to efficiently encapsulate R848 and C6-ceramide (C6). Their physicochemical properties were characterized, and the embolization efficiency was validated using decellularized liver and rabbit kidney models. Furthermore, their antitumor activities and mechanism were evaluated in both in vitro and in vivo. R848 and C6 were efficiently encapsulated into RC6CaAlgMS, where they acted synergistically to reprogram tumor-associated macrophages (TAMs) toward an M1-like phenotype and to enhance both exosome secretion and exosome-mediated antigen cross-presentation. RC6CaAlgMS produced uniform vascular embolization and efficiently occluded the renal arterial branches. In vitro studies demonstrated that RC6CaAlgMS synergized with DOX-based chemotherapy to suppress the growth of murine HCC by neutralizing acidic TME and remodeling the immune landscape. When combined with PD-L1 blockade therapy, DOX-loaded RC6CaAlgMS effectively inhibited both primary and distant tumors, eliciting an abscopal-like effect driven by enhanced antigen dissemination and T-cell priming. In an orthotopic rat TACE model, the combination of DOX-loaded RC6CaAlgMS with PD-L1 blockade achieved complete tumor eradication.

This study evaluates the therapeutic potential of exosomes derived from induced pluripotent stem cell-derived mesenchymal stem cells (iPSCMSC-exo) versus umbilical cord-derived MSC exosomes (hUCMSC-exo) for POI intervention. In vitro, both exosome types enhanced migration and tube formation of human umbilical vein endothelial cells (HUVECs), while iPSCMSC-exo additionally promoted proliferation. iPSCMSC-exo attenuated cisplatin-induced granulosa cell apoptosis, while both types suppressed p21-mediated cell cycle arrest. In the cisplatin-induced POI mouse model, exosome treatment effectively restored Follicle-stimulating hormone (FSH) levels. However, the therapeutic efficacy of exosomes in restoring anti-M\u00fcllerian hormone (AMH) levels and follicle counts was limited, as confirmed by synchrotron radiation microtomography revealing persistent structural depletion. Notably, iPSCMSC-exo demonstrated functional outcomes similar to hUCMSC-exo.

Exosomes, as promising endogenous nanocarriers, have emerged as a powerful tool for the prevention and treatment of CVDs. In particular, advanced functionalization strategies have largely enhanced exosomal therapeutic efficacy in\u00a0vivo. Notably, Traditional Chinese Medicine (TCM) and its bioactive components exert profound regulatory effects on exosomes. In this review, we systematically summarize exosome-based therapeutic strategies for CVDs, along with state-of-art functionalization approaches to optimize exosomal cargo loading and targeted delivery. We further provide a comprehensive overview of TCM-mediated exosomal regulation. We found that TCM and TCM-derived chemicals can optimize exosomal cargo loading, especially the loading of microRNAs (miRNAs) and bioactive chemicals. More importantly, TCM and chemicals can promote exosomal secretion, which provides new avenues for exosomal-scale production. Besides, there are synergistic effects between exosomes and TCM when co-administered. Collectively, exosome-based systems hold great promise for CVD therapy, and TCM provides novel strategies for exosomal functionalization, which substantially enhances exosomal-mediated therapeutic efficacy for CVDs."

"abstract_text": "ID: 42522799\nTitle: Oral Squamous Cell Carcinoma: A New Era in Molecular Mechanisms and Emerging Targeted Therapies.\nAbstract: Oral squamous cell carcinoma (OSCC), the most common oral cancer, presents a clinical challenge due to its complex tumor microenvironment (TME), dysregulated pathways, and poor prognosis. Current methods of diagnosing OSCC use liquid biopsy technologies (ctDNA/microRNAs/exosomes) instead of relying solely on traditional methods such as open surgical biopsy. Liquid biopsy technologies provide non-invasive ways to detect and monitor OSCC in early stages, compared with traditional open surgical biopsy methods. Treatment of OSCC currently relies on chemotherapeutics (cisplatin/5-FU), radiotherapy, and targeted agents (cetuximab). However, resistance is acquired due to TME remodelling (tumor microenvironment) and/or due to epithelial-mesenchymal transition (EMT) through processes such as ABC transporter efflux. This review elucidates key molecular mechanisms, including PD-L1-mediated immune evasion, PI3K/AKT/mTOR hyperactivation, EGFR overexpression, and NF-\u03baB-driven inflammation, which promote proliferation, metastasis, and therapy resistance. One area of study involves the use of nanotechnology to convert phytocompounds (medicinal plants) into therapeutic agents by embedding phytocompounds into nanoparticles created using green synthesis techniques. EPR (Enhanced Permeability and Retention), ligand functionalization for OSCC targeting, improved bioavailability, and reduced toxicity are all advantages that the aforementioned systems provide, offering an opportunity to synergistically develop new therapies with chemotherapeutics for overcoming resistance. While numerous preclinical studies demonstrate that these newly developed therapies show increased efficacy compared with current therapy options, further work is needed in areas such as standardization, scaling, and clinical translation. As such, the importance of developing pathway-informed diagnostic tests and developing therapies that exploit pathway-specific activity with phytocompounds is emphasized. In addition, large-scale studies should be considered to evaluate the effectiveness of a pathway-informed approach in assessing and differentiating OSCC and personalized therapy strategies, to improve OSCC survival outcomes."

Nevertheless, despite considerable progress in elucidating its molecular background, early diagnosis and accurate stratification of disease progression remain challenging when relying on conventional clinical biomarkers such as albuminuria and estimated glomerular filtration rate (eGFR). Growing evidence indicates that DKD is driven by interconnected pathogenic mechanisms, including chronic hyperglycemia, activation of the protein kinase C (PKC) signaling pathway, renin-angiotensin-aldosterone system (RAAS) dysregulation, oxidative stress, inflammatory cascades, and immune system activation involving Toll-like receptors (TLR) and the NLRP3 inflammasome. These processes collectively contribute to endothelial dysfunction, podocyte injury, extracellular matrix accumulation, and progressive renal fibrosis. Exosomes and their molecular cargo, particularly miRNAs, have emerged as promising regulators and non-invasive biomarkers reflecting ongoing renal injury. Urinary exosomal microRNAs (uEV-miRNAs) are of interest due to their stability in biological fluids and their direct origin from nephron segments, enabling real-time reflection of renal pathophysiology. Accumulating studies suggest that differentially expressed microRNAs (miRNAs), including miR-21-5p, miR-30a-5p, miR-192-5p, and miR-142-3p, are closely associated with key pathways in DN. However, their clinical translation remains limited by methodological heterogeneity, the lack of standardized isolation protocols, and insufficient validation in large longitudinal cohorts. This review navigates the current landscape of knowledge on the molecular mechanisms underlying DKD and examines the emerging role of uEV-miRNAs as diagnostic biomarkers. Altogether, uEV-miRNAs offer a promising avenue for improving early detection, risk stratification, and disease monitoring in DKD."

The hydrogel was synthesized using polyethylene glycol (PEG), 2-hydroxyethyl methacrylate (HEMA), acrylic acid (AA), with N,N'-methylene bisacrylamide (MBA) as a cross-linker and potassium persulfate (KPS) as an initiator. The hydrogel's structural integrity and formation were confirmed through Fourier-transform infrared spectroscopy (FTIR), scanning electron microscopy (SEM), differential scanning calorimetry (DSC), and swelling studies. It is noteworthy that the hydrogel exhibits a different pH-dependent swelling behaviour, which expands under alkaline conditions and maintains its compact structure under acidic conditions. The content of acrylic acid contributed to the high-water retention and the swelling profile indicated that the product was suitable for the specific release of the drug at the site. The in-vitro release of rabeprazole sodium at acidic pH is very low, thus protecting rabeprazole sodium from premature degradation in the stomach; however, controlled release of rabeprazole sodium was achieved at intestinal pH via a non-Fickian diffusion mechanism (Korsmeyer-Peppas n = 0.40-0.62, Higuchi R\u00b2 = 0.991-0.996) over 12 h. Moreover, in-vivo acute toxicity studies indicated that the hydrogel is highly biocompatible, suggesting it is safe for use in future therapeutic applications. Overall, the PEG (HEMA-co-AA) hydrogel represents a versatile vehicle for the controlled and local administration of acid-labile pharmaceuticals, thereby promoting increased therapeutic efficacy."

The core mechanisms underlying these diseases include impaired T-cell and B-cell immune tolerance, abnormal cytokine production, and aberrant activation of related signaling pathways. Conventional treatments primarily focus on suppressing immune responses, but their efficacy remains limited and they are often associated with substantial side effects. Nanomedicine leverages nanoscale materials to enable precise diagnosis and targeted therapy. Nanocarriers can penetrate biological barriers, enhance cellular uptake, and prolong circulation time in vivo, demonstrating considerable potential for drug delivery. Common nanoscale drug delivery platforms include nanoparticles, polymeric micelles, liposomes, dendrimers, mesoporous materials, hydrogels, and exosomes. Each carrier type possesses distinct characteristics in terms of drug-loading capacity, stability, responsiveness, and biocompatibility, thereby enabling targeted delivery and controlled release. This review summarizes recent advances in nano-delivery technologies for three representative chronic autoimmune diseases: diabetes mellitus (DM), inflammatory bowel disease (IBD), and rheumatoid arthritis (RA). Nano-delivery systems can improve therapeutic outcomes by optimizing drug delivery, targeting complications, and modulating the pathological microenvironment.

Mechanistic studies demonstrated that RVG-EXOs inhibited RPTOR expression, thereby activating the autophagy pathway and promoting the clearance of pathological proteins. Both in vitro and in vivo experiments confirmed that overexpression of RPTOR significantly suppressed the therapeutic effects of RVG-EXOs. single-cell transcriptomic profiling further revealed that RVG-EXOs not only increased neuronal proportion and modulated excitatory/inhibitory neuronal balance but also reshaped the microglial landscape by reducing deleterious disease-associated while increasing homeostatic surveillant microglia. In summary, this study not only reveals for the first time the potential value of young plasma-derived EXOs in AD treatment but also, through RVG engineering strategies and the elucidation of the RPTOR-autophagy mechanism, provides new insights for targeted therapy of neurodegenerative diseases."

Probiotics and postbiotics represent promising preclinical candidates to alleviate these unmet clinical bottlenecks. Bacterial extracellular vesicles (BEVs) are naturally secreted bacterial nanovesicles carrying abundant bioactive cargos, whose bioactivity and safety are highly strain-dependent. Probiotics-derived BEVs can remodel gut homeostasis, repair epithelial barriers, and regulate mucosal immunity to suppress the inflammatory vicious cycle in IBD, while pathogen-/pathobiont-derived BEVs loaded with lipopolysaccharide and virulence factors exacerbate intestinal inflammation. Native BEVs are restricted by low cargo loading, poor gastrointestinal stability and inadequate colon tropism. Rational engineering strategies, including surface modification, self-loading hybridization, genetic manipulation, and pH-responsive coating, can optimize the therapeutic performance of BEVs. This review systematically summarizes BEVs biological mechanisms, engineering approaches, and translational obstacles and outlines prospects for the design of intelligent multifunctional BEVs and standardized large-scale manufacturing as future directions, providing theoretical support for oral BEVs nanotherapies against IBD."

Ischemia triggers robust microglial activation, yet the precise regulatory mechanisms underlying microglial functional reprogramming remain incompletely understood. Here, we demonstrate that excessive mitophagy drives metabolic energy failure in microglia following cerebral ischemia, resulting in impaired phagocytosis and exacerbated neuroinflammation. Analysis of single-cell RNA-sequencing data from mouse brains in the sham, transient middle cerebral artery occlusion (tMCAO, mMCAO), and permanent middle cerebral artery occlusion (pMCAO, sMCAO) groups revealed that mitophagy was markedly activated in microglia under sustained ischemia and was associated with impaired phagocytic and cytoskeletal pathways. In vitro oxygen-glucose deprivation (OGD) assays showed that phagocytosis of apoptotic neurons by microglia induced upregulation of Drp1, triggering excessive mitochondrial fission and mitophagy, which caused ATP depletion and reduced clearance capacity. The mitophagy inhibitor 3-methyladenine alleviated inflammatory responses but failed to restore mitochondrial quality. In contrast, 3-n-butylphthalide (NBP) stabilized mitochondrial membrane potential, restored ATP production, and improved microglial phagocytic defects and inflammation. To achieve targeted delivery, we constructed BV2 microglia-derived exosomes encapsulating NBP (BV2exo@ NBP), which efficiently enhanced drug accumulation in ischemic lesions and significantly improved neurological outcomes in stroked mice. These results identify excessive mitophagy as a core mechanism underlying microglial energy crisis after cerebral ischemia and provide a mitochondria-targeted therapeutic strategy for ischemic stroke. Importantly, the neuroprotective efficacy, mitochondrial restoration, and anti-inflammatory effects of BM@NEB were fully recapitulated in 18-month-old aged mice, a clinically relevant model that more closely reflects the stroke patient population, supporting the translational potential of this exosome-based therapeutic strategy."

Moreover, the therapeutic efficacy of exosomes can be substantially enhanced through functional modifications and the incorporation of bioactive molecules. In this study, the MSCs were cultured under two-dimensional (2D) and three-dimensional (3D) cell culture conditions. The culture supernatants were collected for isolating exosomes. The characteristics and yields of exosomes from 2D and 3D cultures were detected by nanoparticle tracking analysis (NTA), transmission electron microscopy (TEM), western blot analysis, and bicinchoninic acid (BCA) assay. Subsequently, 3D exosomes were loaded with miR-99b-5p and modified with iRGD peptide were formed into a new engineered exosome, designated as iRGD-Exo-miR-99b-5p. The effects of these engineered exosomes on the progression of colorectal cancer (CRC) were assessed through a series of in vivo and in vitro experiments. The 3D-cultured MSCs exhibited a higher yield of exosomes and enhanced uptake by CRC cells. Further in vitro experiments demonstrated that 3D-exosomes loaded with miR-99b-5p effectively inhibit the proliferation, invasion, migration and epithelial-mesenchymal transition (EMT) of CRC cells. Results from a xenograft tumor model indicate that iRGD-modified exosomes were significantly enriched at tumor sites. Furthermore, exosomes modified with iRGD and loaded with miR-99b-5p were employed for CRC treatment, resulting in substantial tumor growth inhibition and enhanced the chemotherapy efficacy of 5-fluorouracil (5-FU) in vivo, without inducing notable toxicity or side effects. Mechanistically, exosome-mediated delivery of miR-99b-5p downregulated FGFR3 expression, thereby inhibiting the activation of the PI3K/AKt signaling pathway and promoting ferroptosis, ultimately attenuating CRC progression. Collectively, iRGD-modified 3D exosomes loaded with miR-99b-5p were able to specifically target tumor sites, thereby significantly suppressing CRC growth through the induction of ferroptosis via regulating the FGFR3/PI3K/AKt signaling pathway. These findings suggest that functional engineering and bioactive loading of 3D-exosomes derived from MSCs represent a promising strategy for targeted cancer therapy."

Exosomes (Exos) are key mediators of intercellular communication and promising vehicles for targeted therapy. This study aimed to investigate the function and underlying mechanism of exercise-derived exosomes (Exe-Exos) in SCI recovery. Circulating Exos were isolated from rats subjected to a 4-week treadmill Exe regimen and from sedentary controls. A gelatin methacrylate (GelMA) hydrogel microneedles (Hyd MNs) system was developed for the targeted, sustained delivery of these Exos directly to the injury epicenter at the T10 spinal segment in a rat SCI model. Using integrated in vitro and in vivo approaches, we showed that Exe-Exos significantly promoted motor function recovery, attenuated tissue damage, reduced apoptosis, and alleviated both inflammation and oxidative stress (Oxs) after SCI. Small RNA sequencing revealed that miR-151-3p is a key functional cargo that is enriched in Exe-Exos. Gain- and loss-of-function studies revealed that exosomal miR-151-3p exerts its protective effects by directly targeting the mitochondrial membrane protein ROMO1. This targeting led to the coordinated inhibition of the pro-apoptotic JNK/Caspase pathway, suppression of the NF-\u03baB-mediated inflammatory cascade, and activation of the Nrf2/HO-1 antioxidant axis. Collectively, our findings establish Exe-Exos, specifically exosomal miR-151-3p, as an exercise-responsive circulating signaling axis that orchestrates multifaceted protection against secondary injury after SCI, offering an innovative, mechanism-based strategy for neuroregenerative therapy."

They play a key role in intercellular communication by transferring proteins, lipids, and nucleic acids. In cancer, EVs contribute to remodelling the tumor microenvironment, enhancing angiogenesis, modulating immune responses, promoting metastasis, and driving therapeutic resistance. This narrative review aims to highlight the biological importance and clinical relevance of EVs in cancer, focusing on their potential as biomarkers and therapeutic tools. A comprehensive literature search was conducted using PubMed, Scopus, and Web of Science. Studies on EV composition, isolation, and characterization methods, as well as recent advances in EV bioengineering, were critically examined to summarize their significance in oncology. Findings reveal that the molecular cargo of EVs reflects the physiological and pathological states of their source cells, supporting their role as non-invasive biomarkers for cancer detection and monitoring. EVs also regulate signaling pathways that sustain tumor heterogeneity and adaptability. Moreover, engineered EVs demonstrate strong potential as delivery systems for chemotherapeutic agents, RNA-based drugs, and immunomodulators, underscoring their translational value in targeted therapy.

In recent years, nanotechnology has provided a new strategy for the treatment and diagnosis of IBD due to its advantages of precise delivery, controllable release and multifunctional integration. We searched the Web of Science Core Collection database for relevant literature about nanotechnology and IBD published from 2005 to 2024. We used SciExplorer, VOSviewer, and Citespace to analyze countries, institutions, authors, keywords, highly cited references, and co-cited references to discuss research hotspots and trends in this field. The research analysis included a total of 959 pieces of literature, with China and the USA leading in the number of papers published and academic influence.

In recent years, exosomes (Exos), nanoscale vesicles involved in intercellular communication, have attracted increasing attention for their roles in the formation and spread of MDR. A growing body of evidence suggests that Exos mediate the transfer of resistance-related molecular signals among drug-resistant cancer cells, drug-sensitive cancer cells, and stromal cells, such as cancer-associated fibroblasts and tumor-associated macrophages, through the selective packaging of noncoding RNAs, functional proteins, and metabolic regulators. These molecular signals may induce the reprogramming of signaling pathways, metabolism, and epigenetic states in recipient cells, thereby promoting the acquisition of cancer stem cell-like properties and a drug-resistant phenotype. In turn, these changes may contribute to the establishment of a drug resistance-supporting tumor microenvironment. This review systematically summarizes the molecular mechanisms by which Exos contribute to multidrug resistance, with a particular focus on their roles in cargo sorting, microenvironmental crosstalk, and the functional reprogramming of recipient cells. It also discusses their potential for clinical translation in resistance monitoring and reversal therapy.

The secreted extracellular vesicles (EVs) of organoids, in particular the small-sized EV subset referred as exosomes (30-200\u00a0nm), have emerged as novel therapeutics in regenerative medicine. This study investigated the encapsulation and controlled release of human spinal cord organoid (hSCO)-derived EVs in viscoelastic hyaluronic acid (HA) hydrogels and assessed their impact on organoid patterning. A series of pH-responsive hydrogels were fabricated, leading to sustained EV release regulated by viscoelastic properties. The pH of these hydrogels decreased from 9 to 7 during incubation, which altered hydrogel viscoelasticity, thereby modulating EV release kinetics. In addition, EV-loaded hydrogels regulated key hSCO patterning markers such as DBX1 and ISL1. Furthermore, these EVs in hydrogels can cross a modeled blood-spinal cord barrier and provide cross-barrier capability for delivery. Taken together, the organoid-secreted EVs in viscoelastic HA hydrogels can be released at a controlled rate and have potential to regulate spinal cord organoid patterning.

Luteolin (LUT) is a poorly water-soluble natural anti-angiogenic agent. To address this limitation, we develop an ion- and pH-responsive in situ gel system (LUT-NLC-ISG) by incorporating LUT-loaded nanostructured lipid carriers (LUT-NLC) into a gellan gum/Carbopol matrix, aiming to enhance ocular bioavailability and therapeutic efficacy against CNV. Methods: LUT-NLC-ISG was optimized using a central composite design-response surface methodology (CCD-RSM) and characterized by physicochemical properties (particle size, viscosity, gelation behavior). Ocular pharmacokinetics and biodistribution were evaluated in rabbits after a single topical administration. Biocompatibility was assessed via Hen's egg test-chorioallantoic membrane assay (HET-CAM), Draize tests, and cytotoxicity studies. Therapeutic efficacy and mechanism were investigated in a murine model of alkali burn-induced CNV. Results: The optimized LUT-NLC-ISG had a particle size of 25.27 \u00b1 0.23 nm and exhibited a 45-fold viscosity increase upon simulated tear fluid (STF) exposure. In rabbits, LUT-NLC-ISG significantly increased the bioavailability of LUT in ocular tissues compared with LUT-NLC alone, with 2.57-, 1.83-, and 10.59-fold higher area under the concentration-time curve (AUC) in the cornea, conjunctiva, and tears, respectively and exhibited excellent ocular biocompatibility. In the CNV mouse model, 0.1% (w/v) LUT-NLC-ISG effectively inhibited corneal neovascularization, comparable to 0.025% dexamethasone, and downregulated VEGF-A and MMP-9 expression. Conclusions: LUT-NLC-ISG synergistically combines NLC technology and dual-sensitive in situ gelation to significantly improve LUT ocular bioavailability, offering a promising non-invasive candidate for CNV management."

This review highlights recent advances in exosome biology, cargo-sorting mechanisms, and engineering strategies designed to enhance therapeutic delivery and targeting within the central nervous system. Particular emphasis is placed on the application of engineered exosomes in neurodegenerative diseases, stroke, spinal cord injury, neuropathic pain, and neuroinflammatory disorders. In addition, we discuss how exosomes compare with conventional delivery platforms and critically examine the major barriers limiting their clinical translation, including heterogeneity, scalability, reproducibility, purity, and regulatory standardization. By integrating mechanistic insights with translational perspectives, this review provides a framework for the rational design and future clinical implementation of exosome-based nanomedicines for neurological disorders. Relevant literature was identified through searches of PubMed, Scopus, Web of Science, and Google Scholar. Publications available from database inception through [Month Year] were screened using combinations of keywords including \"exosomes,\" \"extracellular vesicles,\" \"neurological disorders,\" \"brain-targeted delivery,\" \"exosome engineering,\" \"drug delivery,\" and \"clinical trials.\" Additional relevant articles were identified through manual searches of reference lists from selected studies and recent reviews. Exosomes are tiny natural particles released by cells that act as messengers, carrying proteins and genetic material between cells. Scientists are increasingly studying these particles because they may help deliver medicines to the brain and spinal cord, where many treatments struggle to reach due to protective barriers. This review explains how exosomes are formed, how they can be modified to carry drugs or therapeutic molecules, and how they may help treat diseases affecting the nervous system, including Alzheimer\u2019s disease, Parkinson\u2019s disease, stroke, multiple sclerosis, spinal cord injury, and certain neuropsychiatric disorders.We also discuss the advantages of exosomes compared with conventional drug delivery systems and summarize recent advances in engineering strategies that improve their targeting abilities. Although laboratory studies have produced encouraging results, many challenges remain before exosome-based therapies can become routine treatments. These include difficulties related to large-scale production, quality control, safety, and ensuring that exosomes reach the desired tissues without causing unwanted effects.In addition, this review highlights current clinical studies and discusses the steps needed to translate these discoveries into real-world therapies. Overall, exosomes represent an exciting and rapidly evolving area of research that may contribute to the development of safer and more effective treatments for neurological disorders in the future."

To address these critical challenges, we developed an innovative dual-targeted nanoplatform (Exo-SPIONs-SRF/CGA) that synergistically combines the natural tumour-homing capability of HCC-derived exosomes with the magnetic guidance of superparamagnetic iron oxide nanoparticles (SPIONs) for precision drug targeting. This nanoplatform co-encapsulates SRF and CGA to improve the therapeutic index by enhancing desired responses and minimizing undesired side effects. The exosome component provides inherent biological targeting to HCC cells. At the same time, the incorporated SPIONs enable external magnetic field-guided spatial control, collectively ensuring superior tumour accumulation compared to conventional delivery systems. Furthermore, the platform's tumour microenvironment-responsive release characteristics ensure localized drug activation, maximizing the therapeutic index through spatial and temporal control of drug availability. In vitro and in vivo evaluations demonstrated that this nanoplatform significantly enhances tumour suppression and drug retention while reducing systemic side effects compared to monotherapies or single-modality nanocarriers. The Exo-SPIONs-SRF/CGA platform represents a promising strategy in HCC treatment, addressing fundamental limitations of current therapies by simultaneously overcoming biological barriers to drug delivery, enhancing therapeutic efficacy through synergistic drug combinations, and minimizing collateral damage to healthy tissues, thereby advancing the frontier of precision oncology toward more effective and safer HCC management."

It is the first organized immune-stromal site exposed to lymph-borne melanoma-derived extracellular vesicles (EVs), soluble mediators, proteins, lipids, and non-coding RNAs (ncRNAs) before and during metastatic seeding. Current evidence supports a model in which melanoma-derived EVs traffic through lymphatic vessels, enter draining nodes, interact with lymphatic endothelial cells, medullary macrophages, dendritic cells, and T cells, and remodel lymphovascular, stromal, and immune compartments. Key vesicle-associated mechanisms include NGFR/p75NTR-positive small extracellular vesicles (sEVs) that drive lymphangiogenesis and nodal metastasis, PD-L1-positive vesicles that suppress T-cell activation, CD36-linked pathways that reshape myeloid lipid metabolism, and uPAR-associated vesicles that promote endothelial and matrix remodeling.

While T-cell activation is implicated, the role of soluble programmed death-1 (sPD-1), primarily derived from activated T cells, in PF pathogenesis remains elusive. We initially analyzed serum sPD-1 levels in PD patients and employed a mice PF model induced by high-glucose dialysate and lipopolysaccharide (LPS). The functional impact of sPD-1 on the progression of PF was assessed through the administration of a PD-L1 fusion protein, or engineered exosomes designed to adsorb sPD-1. Serum sPD-1 levels were significantly elevated in long-term PD patients and were positively correlated with dialysis duration and markers of fibrosis, but inversely correlating with peritoneal function. In mice, exogenous sPD-1 exacerbated PF, whereas blockade with a PD-L1 fusion protein or sPD-1-adsorbing engineered exosomes markedly attenuated fibrosis, reduced T-cell infiltration, and preserved peritoneal function. Mechanistically, sPD-1 bound to PD-L1 on PMCs, triggering clathrin-mediated endocytosis. This interaction diverted PD-L1 from the lysosomal degradation pathway towards the Rab11-positive recycling endosome pathway, resulting in sustained upregulation of surface PD-L1 expression. This aberrant PD-L1 recycling activated pro-fibrotic signaling, culminating in mesothelial-to-mesenchymal transition (MMT). sPD-1 is a pivotal mediator linking peritoneal microinflammation to fibrosis by modulating the endocytic fate of PD-L1 in mesothelial cells. Targeting sPD-1, particularly using engineered exosomes or a PD-L1 fusion protein, represents a promising therapeutic strategy for preventing and treating peritoneal fibrosis."

This recalcitrance stems largely from loss-of-function mutations within the low-density lipoprotein receptor (LDLR) gene, which severely undermine the efficacy of standard therapeutic regimens. Here, we report a bioinspired \"targeting and blockade\" strategy for the efficient delivery of functional Ldlr mRNA to hepatocytes. This approach is realized through a rationally designed platform, Szd\u00a0+\u00a0AP@ExoE-Ldlr, which integrates APOA1-functionalized exosomes for hepatocyte-targeted delivery with a preemptive macrophage blockade using the clinical ultrasound contrast agent Sonazoid (Szd). The APOA1 modification confers specific recognition by the scavenger receptor class B type 1 on hepatocytes, while the pre-saturation of Kupffer cells with Szd significantly mitigates nonspecific clearance by the mononuclear phagocyte system (MPS). In a HoFH murine model, this synergistic strategy markedly enhanced the accumulation of exosomes in hepatocytes and achieved robust restoration of hepatic LDLR expression. Consequently, it elicited a profound correction of the atherogenic lipid profile and substantially attenuated the progression of atherosclerosis. A comprehensive biosafety evaluation confirmed the excellent biocompatibility of this platform. Our work provides a promising and broadly applicable solution for the treatment of liver-related genetic disorders by simultaneously overcoming the critical barriers of targeted delivery and MPS evasion."

Cuproptosis has emerged as a promising mechanism by which to inhibit tumors because copper homeostasis disorders frequently occur in various malignancies. The combination of disulfiram (DSF) and copper ions (DSF/Cu) has been shown to have significant antitumor effects. This study utilized DSF/Cu to investigate the mechanism underlying cuproptosis in GC cells. GC cells were treated with DSF/Cu and protein sequencing was performed to screen for differentially expressed genes. The mechanism by which overexpressed FDX1 regulates cuproptosis and WDR43 expression was determined. Subsequently, how to improve the efficacy of DSF/Cu in the treatment of GC was studied in a mouse model of GC. DSF/Cu had a good therapeutic effect on promoting cuproptosis in GC cells. Protein sequencing revealed WDR43 as a downstream gene of FDX1. Increasing the expression of FDX1 enhanced the sensitivity of GC cells to copper treatment and inhibited the expression of WDR43, thereby exerting an antitumor effect. Furthermore, DSF/Cu was loaded into exosomes derived from natural killer (NK) cells to enhance the biological safety and tumor targeting of DSF/Cu and validate the inhibitory effect on GC both in vitro and in vivo. This study showed that DSF/Cu promoted cuproptosis and the expression of FDX1 affected cuproptosis sensitivity of GC. Moreover, the combination of NK cell exosomes with DSF/Cu improved the therapeutic effect of DSF/Cu, which helps to promote the targeted therapy of GC and improve clinical applicability."

Exosomes (Exos) are key mediators of intercellular communication and promising vehicles for targeted therapy. This study aimed to investigate the function and underlying mechanism of exercise-derived exosomes (Exe-Exos) in SCI recovery. Circulating Exos were isolated from rats subjected to a 4-week treadmill Exe regimen and from sedentary controls. A gelatin methacrylate (GelMA) hydrogel microneedles (Hyd MNs) system was developed for the targeted, sustained delivery of these Exos directly to the injury epicenter at the T10 spinal segment in a rat SCI model. Using integrated in vitro and in vivo approaches, we showed that Exe-Exos significantly promoted motor function recovery, attenuated tissue damage, reduced apoptosis, and alleviated both inflammation and oxidative stress (Oxs) after SCI. Small RNA sequencing revealed that miR-151-3p is a key functional cargo that is enriched in Exe-Exos. Gain- and loss-of-function studies revealed that exosomal miR-151-3p exerts its protective effects by directly targeting the mitochondrial membrane protein ROMO1. This targeting led to the coordinated inhibition of the pro-apoptotic JNK/Caspase pathway, suppression of the NF-\u03baB-mediated inflammatory cascade, and activation of the Nrf2/HO-1 antioxidant axis. Collectively, our findings establish Exe-Exos, specifically exosomal miR-151-3p, as an exercise-responsive circulating signaling axis that orchestrates multifaceted protection against secondary injury after SCI, offering an innovative, mechanism-based strategy for neuroregenerative therapy."

In this study, we systematically evaluated the anti-tumor effect of Bi2536, an inhibitor of Polo-like kinase 1 (PLK1), in HGSOC, and clarified its mechanism. Bi2536 inactivates PLK1, leading to the subsequent inactivation of cyclin-dependent kinase 1 (CDK1). This disruption triggers a cascade of antitumor effects, including G2/M phase arrest, induction of mitochondrial apoptosis, and suppression of cell migration and invasion. Furthermore, we identified circadian oscillations in PLK1 expression both in HGSOC cells and in vivo xenograft models. To enhance therapeutic precision and minimize systemic toxicity, we engineered a biomimetic nano-delivery system for Bi2536. This integrated platform combines chemotherapy and chemodynamic therapy (CDT), significantly improving antitumor outcomes. Importantly, synchronizing Bi2536 administration with the circadian peaks of PLK1 expression further augmented its therapeutic efficacy. In summary, our work establishes that the combination of Bi2536 with a biomimetic nano-delivery system, together with its chronotherapeutic administration, constitutes a highly promising and multifaceted strategy for the treatment of HGSOC."

We used SciExplorer, VOSviewer, and Citespace to analyze countries, institutions, authors, keywords, highly cited references, and co-cited references to discuss research hotspots and trends in this field. The research analysis included a total of 959 pieces of literature, with China and the USA leading in the number of papers published and academic influence.

Nanotechnology offers multi-level strategies to overcome multidrug resistance in castration-resistant prostate cancer, including PROTAC-mediated protein degradation, ferroptosis induction, and synergistic chemo-immunotherapy. Multifunctional theranostic nanoplatforms integrating imaging and therapy enable real-time efficacy assessment and personalized treatment adaptation.

In this study, pH-sensitive, core-shell hydrogel microcapsules were designed and fabricated using a BUCHI B-390 microsphere preparation device via electrostatic interactions and hydrogen bonds. Olsalazine sodium was encapsulated in the microcapsules, allowing for pH-responsive drug release in colon tissue for UC treatment in mice. XRD studies demonstrated the amorphous state of the drug in the formulation. The preparation of SCO microcapsules was optimized based on the drug encapsulation efficiency and the drug loading capacity, with the S2C1O microcapsule having the highest drug encapsulation efficiency (59.2%) and drug loading capacity (21.3%), and the production yield was approximately 62.5%.

This review highlights recent advances in exosome biology, cargo-sorting mechanisms, and engineering strategies designed to enhance therapeutic delivery and targeting within the central nervous system. Particular emphasis is placed on the application of engineered exosomes in neurodegenerative diseases, stroke, spinal cord injury, neuropathic pain, and neuroinflammatory disorders. In addition, we discuss how exosomes compare with conventional delivery platforms and critically examine the major barriers limiting their clinical translation, including heterogeneity, scalability, reproducibility, purity, and regulatory standardization. By integrating mechanistic insights with translational perspectives, this review provides a framework for the rational design and future clinical implementation of exosome-based nanomedicines for neurological disorders. Relevant literature was identified through searches of PubMed, Scopus, Web of Science, and Google Scholar. Publications available from database inception through [Month Year] were screened using combinations of keywords including \"exosomes,\" \"extracellular vesicles,\" \"neurological disorders,\" \"brain-targeted delivery,\" \"exosome engineering,\" \"drug delivery,\" and \"clinical trials.\" Additional relevant articles were identified through manual searches of reference lists from selected studies and recent reviews. Exosomes are tiny natural particles released by cells that act as messengers, carrying proteins and genetic material between cells. Scientists are increasingly studying these particles because they may help deliver medicines to the brain and spinal cord, where many treatments struggle to reach due to protective barriers. This review explains how exosomes are formed, how they can be modified to carry drugs or therapeutic molecules, and how they may help treat diseases affecting the nervous system, including Alzheimer\u2019s disease, Parkinson\u2019s disease, stroke, multiple sclerosis, spinal cord injury, and certain neuropsychiatric disorders.We also discuss the advantages of exosomes compared with conventional drug delivery systems and summarize recent advances in engineering strategies that improve their targeting abilities. Although laboratory studies have produced encouraging results, many challenges remain before exosome-based therapies can become routine treatments. These include difficulties related to large-scale production, quality control, safety, and ensuring that exosomes reach the desired tissues without causing unwanted effects.In addition, this review highlights current clinical studies and discusses the steps needed to translate these discoveries into real-world therapies. Overall, exosomes represent an exciting and rapidly evolving area of research that may contribute to the development of safer and more effective treatments for neurological disorders in the future."

Magnetic resonance imaging (MRI) has been utilized as a noninvasive alternative but is limited by low sensitivity, with only \u223c35% of LN metastases detected, as clinical contrast agents cannot discriminate between healthy and metastatic LNs due to nonspecific accumulation. Nanoparticles targeted to the C-C chemokine receptor 2 (CCR2), a biomarker highly expressed in metastatic LNs, have the potential to guide the delivery of contrast agents, improving the sensitivity of MRI. Additionally, cancer cells in metastatic LNs produce monocyte chemotactic protein 1 (MCP1), which binds to CCR2+ inflammatory monocytes and stimulates their migration. Thus, the molecular targeting of CCR2 may enable nanoparticle hitchhiking onto monocytes, providing an additional mechanism for metastatic LN targeting and early detection. Hence, we developed micelles incorporating gadolinium (Gd) and peptides derived from the CCR2-binding motif of MCP1 (MCP1-Gd) and evaluated the potential of MCP1-Gd to detect LN metastasis. When incubated with migrating monocytes in vitro, MCP1-Gd transport across lymphatic endothelium increased 2-fold relative to nontargeting controls. After administration into mouse models with initial LN metastasis and recurrent LN metastasis, MCP1-Gd detected metastatic LNs by increasing MRI signal by 30-50% relative to healthy LNs.

While metabolites within the metastatic niche are increasingly recognized as determinants of organotropic metastasis, the role of exosome-mediated metabolite transfer in tumor-lymphatic endothelial cell (LEC) crosstalk remains largely unexplored. Here, we demonstrate that oleic acid (OA) is significantly enriched in both CC lymph node metastases and the peritumoral lymphatic microenvironment. Exosomes derived from highly metastatic CC cells actively package OA in a manner dependent on stearoyl-CoA desaturase (SCD), the rate-limiting enzyme of de novo fatty acid synthesis. Upon internalization by LECs, exosomal OA triggers the AKT/mTOR signaling axis, eliciting robust LEC proliferation and endothelial-to-mesenchymal transition (EndMT), thereby fostering lymphangiogenesis and nodal colonization. Knockdown of SCD abolishes these pro-lymphangiogenic effects, a deficit fully reversed by the reconstitution of OA-loaded exosomes. In vivo, exosomes from SCD-silenced cells exhibit a severely compromised capacity to drive primary tumor growth, intratumoral lymphangiogenesis, and lymph node metastasis (LNM). Notably, free OA administration exerts substantially weaker effects than its exosomal counterpart, underscoring the superior efficiency of exosome-mediated metabolite trafficking. Clinically, FASN and SCD expression are significantly upregulated in lymph node-positive specimens and positively correlate with lymphatic vessel density and p-AKT levels. Furthermore, circulating exosomal OA levels are significantly elevated in patients with nodal involvement, suggesting its potential as a non-invasive diagnostic biomarker. Collectively, our findings establish a paradigm wherein tumor-derived exosomes function as specialized vehicles for intercellular OA transfer, activating the AKT/mTOR pathway to license lymphangiogenic reprogramming. This work identifies exosomal metabolite shuttling as a central node in tumor-lymphatic communication and proposes targeting OA synthesis or exosomal delivery as a promising therapeutic strategy against CC metastasis."

Protein-based nanocarriers, such as the heavy chain of human ferritin (FTH1), facilitate transferrin receptor-mediated transport across the blood-brain barrier. Here, we present multifunctional FTH1 nanocages as a unified nanoplatform for dual-drug chemotherapy and molecular imaging. The nanocages achieve > 98\u202f% gallium-68 labeling efficiency and enable pH-responsive release of doxorubicin and paclitaxel. In isocitrate dehydrogenase (IDH)-wildtype and IDH-mutant tumor models in ovo, FTH1 nanocages exhibit robust intracerebral distribution, tumor accumulation, and enhanced therapeutic efficacy. Dual-drug nanocages significantly reduce tumor growth (p\u202f<\u202f0.001), with a stronger effect in the IDH-mutant model (p\u202f<\u202f0.001), and improve embryo survival. Kinomic profiling reveals broad suppression of AGC and CMGC kinase families, consistent with attenuation of pro-survival and cell-cycle signaling, particularly in IDH-mutant models. These findings suggest treatment-associated kinase network adaptation linked to the IDH status of the models, consistent with increased therapeutic vulnerability, and support further evaluation of FTH1 nanocages as a platform for improved glioma treatment."

A key approach involves reprogramming tumor-associated macrophages (TAMs) from a protumorigenic M2 phenotype to an antitumorigenic M1 state. However, elevated lactate concentration in the TME not only sustains the M2 phenotype but also impairs therapeutic efficacy. To address this challenge, we developed an in situ injectable carboxymethyl chitosan/oxidized sodium alginate (CMCS/OSA) hydrogel with pH-responsive release properties, coloaded with another nanosized active polysaccharide \u03b2-glucan and a lactate-depleting agent lactate oxidase (LOX). Under the acidic conditions of the TME, Schiff base bonds within the hydrogel matrix dissociate, triggering the controlled release of \u03b2-glucan nanoparticles and LOX. The \u03b2-glucan nanoparticles specifically target TAMs via the dendritic cell-associated C-type lectin 1 (Dectin 1) receptor, facilitating their phenotypic conversion from M2 to M1. Simultaneously, the released LOX continuously degrades lactate, preventing the reversion of TAMs back to the M2 phenotype. Collectively, our results demonstrated that this nanocomposite polysaccharide hydrogel system effectively promoted and maintained TAM polarization toward the M1 phenotype through the synergistic effects of immune modulation and metabolic regulation, ultimately enhancing the efficacy of tumor immunotherapy."

This study aimed to enhance the sustained release, targeting, and efficacy of AMC via developing an intratumoral, in situ pH-responsive AMC-loaded novasome (IPANF) hydrogel. The optimal AMC-novasome was tailored using Design-Expert\u00ae software and subsequently incorporated into a chitosan/glyceryl monooleate mixture to develop IPANF. The in vivo anti-tumour efficacy and safety profile of the IPANF were evaluated using an Ehrlich ascites carcinoma model. Within 24\u2009h, the IPANF formulation exhibited a significantly sustained drug release by 65.31% compared to the free AMC suspension. The intratumoral IPANF resulted in a profound 96.08% reduction in tumour volume, a 70.46% recovery in body weight, and a suppression of the CA 15-3 and CA 27-29 levels by 92.66% and 91.23%, respectively.

Nevertheless, its therapeutic efficacy remains constrained by the hostile tumor microenvironment (TME), typified by acidity and an immunosuppressive milieu. Here, multifunctional microspheres (RC6CaAlgMS) were developed to neutralize the acidic TME and relieve immunosuppression. The uniform-sized calcium alginate microspheres were fabricated using microfluidic technology, incorporating pH-responsive CaCO3 nanocarriers to efficiently encapsulate R848 and C6-ceramide (C6). Their physicochemical properties were characterized, and the embolization efficiency was validated using decellularized liver and rabbit kidney models. Furthermore, their antitumor activities and mechanism were evaluated in both in vitro and in vivo. R848 and C6 were efficiently encapsulated into RC6CaAlgMS, where they acted synergistically to reprogram tumor-associated macrophages (TAMs) toward an M1-like phenotype and to enhance both exosome secretion and exosome-mediated antigen cross-presentation. RC6CaAlgMS produced uniform vascular embolization and efficiently occluded the renal arterial branches. In vitro studies demonstrated that RC6CaAlgMS synergized with DOX-based chemotherapy to suppress the growth of murine HCC by neutralizing acidic TME and remodeling the immune landscape. When combined with PD-L1 blockade therapy, DOX-loaded RC6CaAlgMS effectively inhibited both primary and distant tumors, eliciting an abscopal-like effect driven by enhanced antigen dissemination and T-cell priming. In an orthotopic rat TACE model, the combination of DOX-loaded RC6CaAlgMS with PD-L1 blockade achieved complete tumor eradication. Collectively, this study establishes a multifunctional microsphere platform that effectively remodels and overcomes the post-TACE immunosuppressive TME, offering a potent strategy for integrating embolization with immunotherapy in HCC."

This study evaluates the therapeutic potential of exosomes derived from induced pluripotent stem cell-derived mesenchymal stem cells (iPSCMSC-exo) versus umbilical cord-derived MSC exosomes (hUCMSC-exo) for POI intervention. In vitro, both exosome types enhanced migration and tube formation of human umbilical vein endothelial cells (HUVECs), while iPSCMSC-exo additionally promoted proliferation. iPSCMSC-exo attenuated cisplatin-induced granulosa cell apoptosis, while both types suppressed p21-mediated cell cycle arrest.

In particular, advanced functionalization strategies have largely enhanced exosomal therapeutic efficacy in\u00a0vivo.

We further provide a comprehensive overview of TCM-mediated exosomal regulation. We found that TCM and TCM-derived chemicals can optimize exosomal cargo loading, especially the loading of microRNAs (miRNAs) and bioactive chemicals. More importantly, TCM and chemicals can promote exosomal secretion, which provides new avenues for exosomal-scale production. Besides, there are synergistic effects between exosomes and TCM when co-administered. Collectively, exosome-based systems hold great promise for CVD therapy, and TCM provides novel strategies for exosomal functionalization, which substantially enhances exosomal-mediated therapeutic efficacy for CVDs."

Current methods of diagnosing OSCC use liquid biopsy technologies (ctDNA/microRNAs/exosomes) instead of relying solely on traditional methods such as open surgical biopsy. Liquid biopsy technologies provide non-invasive ways to detect and monitor OSCC in early stages, compared with traditional open surgical biopsy methods. Treatment of OSCC currently relies on chemotherapeutics (cisplatin/5-FU), radiotherapy, and targeted agents (cetuximab). However, resistance is acquired due to TME remodelling (tumor microenvironment) and/or due to epithelial-mesenchymal transition (EMT) through processes such as ABC transporter efflux. This review elucidates key molecular mechanisms, including PD-L1-mediated immune evasion, PI3K/AKT/mTOR hyperactivation, EGFR overexpression, and NF-\u03baB-driven inflammation, which promote proliferation, metastasis, and therapy resistance. One area of study involves the use of nanotechnology to convert phytocompounds (medicinal plants) into therapeutic agents by embedding phytocompounds into nanoparticles created using green synthesis techniques. EPR (Enhanced Permeability and Retention), ligand functionalization for OSCC targeting, improved bioavailability, and reduced toxicity are all advantages that the aforementioned systems provide, offering an opportunity to synergistically develop new therapies with chemotherapeutics for overcoming resistance. While numerous preclinical studies demonstrate that these newly developed therapies show increased efficacy compared with current therapy options, further work is needed in areas such as standardization, scaling, and clinical translation. As such, the importance of developing pathway-informed diagnostic tests and developing therapies that exploit pathway-specific activity with phytocompounds is emphasized. In addition, large-scale studies should be considered to evaluate the effectiveness of a pathway-informed approach in assessing and differentiating OSCC and personalized therapy strategies, to improve OSCC survival outcomes."

Nevertheless, despite considerable progress in elucidating its molecular background, early diagnosis and accurate stratification of disease progression remain challenging when relying on conventional clinical biomarkers such as albuminuria and estimated glomerular filtration rate (eGFR). Growing evidence indicates that DKD is driven by interconnected pathogenic mechanisms, including chronic hyperglycemia, activation of the protein kinase C (PKC) signaling pathway, renin-angiotensin-aldosterone system (RAAS) dysregulation, oxidative stress, inflammatory cascades, and immune system activation involving Toll-like receptors (TLR) and the NLRP3 inflammasome. These processes collectively contribute to endothelial dysfunction, podocyte injury, extracellular matrix accumulation, and progressive renal fibrosis. Exosomes and their molecular cargo, particularly miRNAs, have emerged as promising regulators and non-invasive biomarkers reflecting ongoing renal injury. Urinary exosomal microRNAs (uEV-miRNAs) are of interest due to their stability in biological fluids and their direct origin from nephron segments, enabling real-time reflection of renal pathophysiology. Accumulating studies suggest that differentially expressed microRNAs (miRNAs), including miR-21-5p, miR-30a-5p, miR-192-5p, and miR-142-3p, are closely associated with key pathways in DN. However, their clinical translation remains limited by methodological heterogeneity, the lack of standardized isolation protocols, and insufficient validation in large longitudinal cohorts. This review navigates the current landscape of knowledge on the molecular mechanisms underlying DKD and examines the emerging role of uEV-miRNAs as diagnostic biomarkers. Altogether, uEV-miRNAs offer a promising avenue for improving early detection, risk stratification, and disease monitoring in DKD."

The hydrogel was synthesized using polyethylene glycol (PEG), 2-hydroxyethyl methacrylate (HEMA), acrylic acid (AA), with N,N'-methylene bisacrylamide (MBA) as a cross-linker and potassium persulfate (KPS) as an initiator. The hydrogel's structural integrity and formation were confirmed through Fourier-transform infrared spectroscopy (FTIR), scanning electron microscopy (SEM), differential scanning calorimetry (DSC), and swelling studies. It is noteworthy that the hydrogel exhibits a different pH-dependent swelling behaviour, which expands under alkaline conditions and maintains its compact structure under acidic conditions. The content of acrylic acid contributed to the high-water retention and the swelling profile indicated that the product was suitable for the specific release of the drug at the site. The in-vitro release of rabeprazole sodium at acidic pH is very low, thus protecting rabeprazole sodium from premature degradation in the stomach; however, controlled release of rabeprazole sodium was achieved at intestinal pH via a non-Fickian diffusion mechanism (Korsmeyer-Peppas n = 0.40-0.62, Higuchi R\u00b2 = 0.991-0.996) over 12 h. Moreover, in-vivo acute toxicity studies indicated that the hydrogel is highly biocompatible, suggesting it is safe for use in future therapeutic applications. Overall, the PEG (HEMA-co-AA) hydrogel represents a versatile vehicle for the controlled and local administration of acid-labile pharmaceuticals, thereby promoting increased therapeutic efficacy."

The core mechanisms underlying these diseases include impaired T-cell and B-cell immune tolerance, abnormal cytokine production, and aberrant activation of related signaling pathways. Conventional treatments primarily focus on suppressing immune responses, but their efficacy remains limited and they are often associated with substantial side effects. Nanomedicine leverages nanoscale materials to enable precise diagnosis and targeted therapy. Nanocarriers can penetrate biological barriers, enhance cellular uptake, and prolong circulation time in vivo, demonstrating considerable potential for drug delivery. Common nanoscale drug delivery platforms include nanoparticles, polymeric micelles, liposomes, dendrimers, mesoporous materials, hydrogels, and exosomes. Each carrier type possesses distinct characteristics in terms of drug-loading capacity, stability, responsiveness, and biocompatibility, thereby enabling targeted delivery and controlled release. This review summarizes recent advances in nano-delivery technologies for three representative chronic autoimmune diseases: diabetes mellitus (DM), inflammatory bowel disease (IBD), and rheumatoid arthritis (RA). Nano-delivery systems can improve therapeutic outcomes by optimizing drug delivery, targeting complications, and modulating the pathological microenvironment. They enhance drug bioavailability, reduce off-target and systemic adverse effects, and provide novel strategies for the precise and efficient treatment of chronic autoimmune diseases."

Luteolin (LUT) is a poorly water-soluble natural anti-angiogenic agent. To address this limitation, we develop an ion- and pH-responsive in situ gel system (LUT-NLC-ISG) by incorporating LUT-loaded nanostructured lipid carriers (LUT-NLC) into a gellan gum/Carbopol matrix, aiming to enhance ocular bioavailability and therapeutic efficacy against CNV.

However, their specific roles and mechanisms in Alzheimer's disease (AD) therapy have not yet been systematically investigated. In this study, the rabies virus glycoprotein-targeting peptide (RVG-29) was conjugated to the surface of young plasma-derived EXOs to construct RVG-engineered EXOs (RVG-EXOs), and their therapeutic potential and underlying mechanisms in AD models were systematically evaluated. In 3\u00d7Tg AD model mice, exogenous administration of young plasma-derived EXOs and their engineered product (RVG-EXOs) revealed that RVG-EXOs could more efficiently enter brain tissue and target neurons, significantly reduce A\u03b2 plaque and phosphorylated Tau (P-Tau) pathological deposition, restore synaptic structure, promote neuronal survival, and improve cognitive behavior. Mechanistic studies demonstrated that RVG-EXOs inhibited RPTOR expression, thereby activating the autophagy pathway and promoting the clearance of pathological proteins. Both in vitro and in vivo experiments confirmed that overexpression of RPTOR significantly suppressed the therapeutic effects of RVG-EXOs. single-cell transcriptomic profiling further revealed that RVG-EXOs not only increased neuronal proportion and modulated excitatory/inhibitory neuronal balance but also reshaped the microglial landscape by reducing deleterious disease-associated while increasing homeostatic surveillant microglia. In summary, this study not only reveals for the first time the potential value of young plasma-derived EXOs in AD treatment but also, through RVG engineering strategies and the elucidation of the RPTOR-autophagy mechanism, provides new insights for targeted therapy of neurodegenerative diseases."

Ischemia triggers robust microglial activation, yet the precise regulatory mechanisms underlying microglial functional reprogramming remain incompletely understood. Here, we demonstrate that excessive mitophagy drives metabolic energy failure in microglia following cerebral ischemia, resulting in impaired phagocytosis and exacerbated neuroinflammation. Analysis of single-cell RNA-sequencing data from mouse brains in the sham, transient middle cerebral artery occlusion (tMCAO, mMCAO), and permanent middle cerebral artery occlusion (pMCAO, sMCAO) groups revealed that mitophagy was markedly activated in microglia under sustained ischemia and was associated with impaired phagocytic and cytoskeletal pathways. In vitro oxygen-glucose deprivation (OGD) assays showed that phagocytosis of apoptotic neurons by microglia induced upregulation of Drp1, triggering excessive mitochondrial fission and mitophagy, which caused ATP depletion and reduced clearance capacity. The mitophagy inhibitor 3-methyladenine alleviated inflammatory responses but failed to restore mitochondrial quality. In contrast, 3-n-butylphthalide (NBP) stabilized mitochondrial membrane potential, restored ATP production, and improved microglial phagocytic defects and inflammation. To achieve targeted delivery, we constructed BV2 microglia-derived exosomes encapsulating NBP (BV2exo@ NBP), which efficiently enhanced drug accumulation in ischemic lesions and significantly improved neurological outcomes in stroked mice. These results identify excessive mitophagy as a core mechanism underlying microglial energy crisis after cerebral ischemia and provide a mitochondria-targeted therapeutic strategy for ischemic stroke. Importantly, the neuroprotective efficacy, mitochondrial restoration, and anti-inflammatory effects of BM@NEB were fully recapitulated in 18-month-old aged mice, a clinically relevant model that more closely reflects the stroke patient population, supporting the translational potential of this exosome-based therapeutic strategy."

Moreover, the therapeutic efficacy of exosomes can be substantially enhanced through functional modifications and the incorporation of bioactive molecules. In this study, the MSCs were cultured under two-dimensional (2D) and three-dimensional (3D) cell culture conditions. The culture supernatants were collected for isolating exosomes. The characteristics and yields of exosomes from 2D and 3D cultures were detected by nanoparticle tracking analysis (NTA), transmission electron microscopy (TEM), western blot analysis, and bicinchoninic acid (BCA) assay. Subsequently, 3D exosomes were loaded with miR-99b-5p and modified with iRGD peptide were formed into a new engineered exosome, designated as iRGD-Exo-miR-99b-5p. The effects of these engineered exosomes on the progression of colorectal cancer (CRC) were assessed through a series of in vivo and in vitro experiments. The 3D-cultured MSCs exhibited a higher yield of exosomes and enhanced uptake by CRC cells. Further in vitro experiments demonstrated that 3D-exosomes loaded with miR-99b-5p effectively inhibit the proliferation, invasion, migration and epithelial-mesenchymal transition (EMT) of CRC cells. Results from a xenograft tumor model indicate that iRGD-modified exosomes were significantly enriched at tumor sites. Furthermore, exosomes modified with iRGD and loaded with miR-99b-5p were employed for CRC treatment, resulting in substantial tumor growth inhibition and enhanced the chemotherapy efficacy of 5-fluorouracil (5-FU) in vivo, without inducing notable toxicity or side effects. Mechanistically, exosome-mediated delivery of miR-99b-5p downregulated FGFR3 expression, thereby inhibiting the activation of the PI3K/AKt signaling pathway and promoting ferroptosis, ultimately attenuating CRC progression. Collectively, iRGD-modified 3D exosomes loaded with miR-99b-5p were able to specifically target tumor sites, thereby significantly suppressing CRC growth through the induction of ferroptosis via regulating the FGFR3/PI3K/AKt signaling pathway. These findings suggest that functional engineering and bioactive loading of 3D-exosomes derived from MSCs represent a promising strategy for targeted cancer therapy."

Exosomes (Exos) are key mediators of intercellular communication and promising vehicles for targeted therapy. This study aimed to investigate the function and underlying mechanism of exercise-derived exosomes (Exe-Exos) in SCI recovery. Circulating Exos were isolated from rats subjected to a 4-week treadmill Exe regimen and from sedentary controls. A gelatin methacrylate (GelMA) hydrogel microneedles (Hyd MNs) system was developed for the targeted, sustained delivery of these Exos directly to the injury epicenter at the T10 spinal segment in a rat SCI model. Using integrated in vitro and in vivo approaches, we showed that Exe-Exos significantly promoted motor function recovery, attenuated tissue damage, reduced apoptosis, and alleviated both inflammation and oxidative stress (Oxs) after SCI. Small RNA sequencing revealed that miR-151-3p is a key functional cargo that is enriched in Exe-Exos. Gain- and loss-of-function studies revealed that exosomal miR-151-3p exerts its protective effects by directly targeting the mitochondrial membrane protein ROMO1. This targeting led to the coordinated inhibition of the pro-apoptotic JNK/Caspase pathway, suppression of the NF-\u03baB-mediated inflammatory cascade, and activation of the Nrf2/HO-1 antioxidant axis. Collectively, our findings establish Exe-Exos, specifically exosomal miR-151-3p, as an exercise-responsive circulating signaling axis that orchestrates multifaceted protection against secondary injury after SCI, offering an innovative, mechanism-based strategy for neuroregenerative therapy."

They play a key role in intercellular communication by transferring proteins, lipids, and nucleic acids. In cancer, EVs contribute to remodelling the tumor microenvironment, enhancing angiogenesis, modulating immune responses, promoting metastasis, and driving therapeutic resistance. This narrative review aims to highlight the biological importance and clinical relevance of EVs in cancer, focusing on their potential as biomarkers and therapeutic tools. A comprehensive literature search was conducted using PubMed, Scopus, and Web of Science. Studies on EV composition, isolation, and characterization methods, as well as recent advances in EV bioengineering, were critically examined to summarize their significance in oncology. Findings reveal that the molecular cargo of EVs reflects the physiological and pathological states of their source cells, supporting their role as non-invasive biomarkers for cancer detection and monitoring. EVs also regulate signaling pathways that sustain tumor heterogeneity and adaptability. Moreover, engineered EVs demonstrate strong potential as delivery systems for chemotherapeutic agents, RNA-based drugs, and immunomodulators, underscoring their translational value in targeted therapy.

In recent years, exosomes (Exos), nanoscale vesicles involved in intercellular communication, have attracted increasing attention for their roles in the formation and spread of MDR. A growing body of evidence suggests that Exos mediate the transfer of resistance-related molecular signals among drug-resistant cancer cells, drug-sensitive cancer cells, and stromal cells, such as cancer-associated fibroblasts and tumor-associated macrophages, through the selective packaging of noncoding RNAs, functional proteins, and metabolic regulators. These molecular signals may induce the reprogramming of signaling pathways, metabolism, and epigenetic states in recipient cells, thereby promoting the acquisition of cancer stem cell-like properties and a drug-resistant phenotype. In turn, these changes may contribute to the establishment of a drug resistance-supporting tumor microenvironment. This review systematically summarizes the molecular mechanisms by which Exos contribute to multidrug resistance, with a particular focus on their roles in cargo sorting, microenvironmental crosstalk, and the functional reprogramming of recipient cells. It also discusses their potential for clinical translation in resistance monitoring and reversal therapy.

The secreted extracellular vesicles (EVs) of organoids, in particular the small-sized EV subset referred as exosomes (30-200\u00a0nm), have emerged as novel therapeutics in regenerative medicine. This study investigated the encapsulation and controlled release of human spinal cord organoid (hSCO)-derived EVs in viscoelastic hyaluronic acid (HA) hydrogels and assessed their impact on organoid patterning. A series of pH-responsive hydrogels were fabricated, leading to sustained EV release regulated by viscoelastic properties. The pH of these hydrogels decreased from 9 to 7 during incubation, which altered hydrogel viscoelasticity, thereby modulating EV release kinetics. In addition, EV-loaded hydrogels regulated key hSCO patterning markers such as DBX1 and ISL1. Furthermore, these EVs in hydrogels can cross a modeled blood-spinal cord barrier and provide cross-barrier capability for delivery. Taken together, the organoid-secreted EVs in viscoelastic HA hydrogels can be released at a controlled rate and have potential to regulate spinal cord organoid patterning.

This review highlights recent advances in exosome biology, cargo-sorting mechanisms, and engineering strategies designed to enhance therapeutic delivery and targeting within the central nervous system. Particular emphasis is placed on the application of engineered exosomes in neurodegenerative diseases, stroke, spinal cord injury, neuropathic pain, and neuroinflammatory disorders. In addition, we discuss how exosomes compare with conventional delivery platforms and critically examine the major barriers limiting their clinical translation, including heterogeneity, scalability, reproducibility, purity, and regulatory standardization. By integrating mechanistic insights with translational perspectives, this review provides a framework for the rational design and future clinical implementation of exosome-based nanomedicines for neurological disorders. Relevant literature was identified through searches of PubMed, Scopus, Web of Science, and Google Scholar. Publications available from database inception through [Month Year] were screened using combinations of keywords including \"exosomes,\" \"extracellular vesicles,\" \"neurological disorders,\" \"brain-targeted delivery,\" \"exosome engineering,\" \"drug delivery,\" and \"clinical trials.\" Additional relevant articles were identified through manual searches of reference lists from selected studies and recent reviews. Exosomes are tiny natural particles released by cells that act as messengers, carrying proteins and genetic material between cells. Scientists are increasingly studying these particles because they may help deliver medicines to the brain and spinal cord, where many treatments struggle to reach due to protective barriers. This review explains how exosomes are formed, how they can be modified to carry drugs or therapeutic molecules, and how they may help treat diseases affecting the nervous system, including Alzheimer\u2019s disease, Parkinson\u2019s disease, stroke, multiple sclerosis, spinal cord injury, and certain neuropsychiatric disorders.We also discuss the advantages of exosomes compared with conventional drug delivery systems and summarize recent advances in engineering strategies that improve their targeting abilities. Although laboratory studies have produced encouraging results, many challenges remain before exosome-based therapies can become routine treatments. These include difficulties related to large-scale production, quality control, safety, and ensuring that exosomes reach the desired tissues without causing unwanted effects.In addition, this review highlights current clinical studies and discusses the steps needed to translate these discoveries into real-world therapies. Overall, exosomes represent an exciting and rapidly evolving area of research that may contribute to the development of safer and more effective treatments for neurological disorders in the future."

The physiological mechanism involves size-dependent interstitial transport, which effectively directs these nanovesicles to the lymphatic system, bypassing first-pass hepatic metabolism. This delivery route serves to modulate the immune microenvironment, promote tissue repair, and inhibit tumor-related progression, effectively utilizing LNs as a strategic depot for therapeutic payload delivery.\n\n### [INTRODUCTION & JUSTIFICATION]\nThe therapeutic application of plant-derived nanovesicles leverages their inherent biocompatibility and size-dependent drainage. \"Prior work has shown that lymphatics transport 10-250 nm nanoparticles from peripheral tissues to the lymph node.\" These vesicles exploit the lymphatic system as a conduit for systemic immune modulation. \"Plant-derived extracellular vesicles offer a naturally safe and anti-inflammatory platform for therapeutic delivery.\" By utilizing intradermal delivery, therapeutic agents reach the LN-resident immune cells with high efficiency. \"After an intradermal injection, a higher retention of EXO-PEG-man is observed in the lymph nodes, which could be used for the efficient delivery of immune stimulators and antigens to the lymph nodes in vivo.\" This interaction is vital, as \"Lymphatic vessels have recently been shown to effectively deliver immune modulatory therapies to the lymph nodes, which enhances their therapeutic efficacy.\" Furthermore, studies regarding ginger-derived nanovesicles and related formulations highlight their structural integrity and ability to be absorbed by target cells to induce therapeutic effects, such as \"Mechanistically, GEBSS induced apoptosis and immunogenic cell death (ICD) in tumor cells.\"\n\n### [DISCUSSION: NOVEL & OVERLOOKED]\n* Plant-derived vesicles often maintain colloidal stability, allowing for reproducible lymphatic trafficking compared to synthetic nanoparticles.\n* The use of microneedle platforms can effectively overcome skin barrier challenges, enhancing the transdermal delivery of these vesicles.\n* The \"PUMP\" principle (Preparation, Unleash, Migration, Planting) characterizes the lifecycle of EVs in the context of lymphatic metastasis, providing a potential framework for therapeutic intervention.\n* Plant-derived nanovesicles can suppress M1 macrophage polarization and preserve epithelial-endothelial integrity, reducing inflammation in pulmonary and dermal tissues.\n* Surface modification with albumin-binding domains or pegylation significantly extends the circulation time and LN accumulation of EVs.\n* Combined modalities, such as plant-EV injection with low-level laser therapy (LLLT), synergistically enhance early dermal regeneration and collagen deposition.\n* The modulation of specific microRNA axes (e.g., miR-125b-5p/Smad2) via EV delivery offers a precision-targeted approach for scar regression and anti-fibrotic therapy.\n\n### [EVIDENCE, METHODOLOGY & CITATIONS]\n1.

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]\n\"The conjugation of plant-derived nanovesicles with pH-responsive or enzyme-cleavable 'hitchhiker' peptides enables triggered release within the lymphatic pre-metastatic niche, thereby enhancing the therapeutic payload concentration specifically at sites of active lymphangiogenesis in patients with early-stage lymphatic metastasis.\"\n\nThis claim is Plausible (5/7) based on the evidence, though direct verification of \"plant-derived nanovesicles\" specifically modified with \"hitchhiker\" peptides for \"lymphatic pre-metastatic niche\" targeting is currently an extrapolation of parallel technologies. The provided literature confirms that (1) plant-derived nanovesicles have therapeutic potential in inflammatory and cancer models, (2) pH-responsive and enzyme-cleavable linkers are effective for site-specific delivery in these models, and (3) targeting biomarkers of lymphatic metastasis (such as CCR2 or VEGF-C pathways) can enhance delivery to the metastatic niche. However, a single study synthesizing all these specific components (plant-EVs + hitchhiker peptide + lymphatic targeting) is not explicitly detailed in the provided set.\n\n### [ABSTRACT & REWRITTEN CLAIM]\nPlant-derived extracellular vesicles (EVs) are emerging as versatile, biocompatible platforms for targeted cancer therapy. While current literature establishes the efficacy of engineering plant-EVs with pH-responsive shells or targeting ligands to modulate tumor environments, the specific coupling of \"hitchhiker\" peptide-mediated lymph node (LN) targeting with pH-triggered payload release in a pre-metastatic niche remains a theoretical design paradigm supported by the synergistic capabilities of these distinct technologies.\n\n### [INTRODUCTION & JUSTIFICATION]\nThe therapeutic application of extracellular vesicles (EVs) has expanded from mere drug vehicles to intelligent, responsive nanoplatforms. By exploiting the acidic microenvironment inherent to tumor progression and sites of inflammation, researchers have developed pH-responsive coatings that ensure cargo protection during circulation and selective release upon accumulation. In the context of early lymphatic metastasis, the pre-metastatic niche provides a distinct physiological landscape. Strategies involving nanoparticle hitchhiking\u2014such as the MCP1-derived peptides\u2014have demonstrated the ability to exploit monocyte-mediated lymphatic transport to achieve significant accumulation in metastatic nodes. By integrating these \"hitchhiker\" mechanisms with the structural stability and cargo-loading capabilities of plant-derived vesicles, it is mechanistically plausible that therapeutic efficacy in nodal disease could be substantially improved. The literature supports that \"Rational engineering strategies, including surface modification, self-loading hybridization, genetic manipulation, and pH-responsive coating, can optimize the therapeutic performance of BEVs.\" Furthermore, the use of targeted agents, such as CCR2-binding peptides, provides a clear roadmap for achieving \"monocyte hitchhiking,\" which is crucial as \"LN targeting was dependent on monocyte hitchhiking, as monocyte depletion decreased accumulation by >70%.\"\n\n### [DISCUSSION: NOVEL & OVERLOOKED]\n* Plant-derived nanovesicles exhibit significant cross-kingdom therapeutic potential due to their conservation of metabolic and immune-related pathways.\n* The use of \"hitchhiking\" onto endogenous circulating cells, such as monocytes, allows for significantly increased transport across the lymphatic endothelium.\n* pH-responsive hydrogel shells enable the protection of sensitive cargos (like siRNAs or enzymes) from premature degradation in the systemic circulation.\n* Targeting the CCR2 pathway allows for the specific recognition of metastatic lymph nodes, where this biomarker is highly expressed.\n* Integration of plant-EVs with inorganic materials (e.g., SPIONs or ZIF-8) offers dual-modal therapy, enabling both spatial guidance and triggered drug release.\n* Pre-metastatic niche formation involves active remodeling of the lymphovascular architecture, providing a window of opportunity for targeted intervention before overt tumor colonization.\n* Microfluidic technology facilitates the fabrication of uniform-sized nanocarriers that improve standardized, large-scale manufacturing potential.\n\n### [EVIDENCE, METHODOLOGY & CITATIONS]\n1.

Prior work has shown that lymphatics transport 10-250 nm nanoparticles from peripheral tissues to the lymph node. However, the surface chemistry required to maximize this transport is poorly understood. Here, we determined the effect of surface poly(ethylene glycol) (PEG) density and size on nanoparticle transport across lymphatic endothelial cells (LECs) by differentially PEGylated model polystyrene nanoparticles. Using an established in-vitro lymphatic transport model, we found PEGylation improved the transport of 100 and 40 nm nanoparticles across LECs 50-fold compared to the unmodified nanoparticles and that transport is maximized when the PEG is in a dense brush conformation or high grafting density (Rf/D\u00a0=\u00a04.9). We also determined that these trends are not size-dependent. PEGylating 40 nm nanoparticles improved transport efficiency across LECs 68-fold compared to unmodified nanoparticles. We also found that PEGylated 100 nm and 40 nm nanoparticles accumulate in lymph nodes within 4 h after intradermal injection, while unmodified nanoparticles accumulated minimally. Densely PEGylated nanoparticles traveled the furthest distance from the injection site and densely PEGylated 40 nm nanoparticles had maximum accumulation in the lymph nodes compared to low density PEGylated and unmodified nanoparticles. Finally, we determined that nanoparticles are transported via both paracellular and transcellular mechanisms, and that PEG conformation modulates the cellular transport mechanisms. Our results suggest that PEG conformation is crucial to maximize nanoparticle transport across LECs and into lymphatic vessels, making PEG density a crucial design. Optimizing PEG density on nanoparticle formulations has the potential to enhance immunotherapeutic and vaccine outcomes. STATEMENT OF SIGNIFICANCE: Lymphatic vessels are an emerging target for drug delivery both in the context of modulating immune responses and enhancing bioavailability by avoiding first pass hepatic metabolism after oral delivery. Lymphatic vessels are the natural conduits from peripheral tissues to the lymph nodes, where the adaptive immune response is shaped, and eventually to systemic circulation via the thoracic duct. Lymphatics can be targeted via nanoparticles, but the surface chemistry required to maximize nanoparticle transport by lymphatics vessels remains poorly understood. Here, we demonstrate that coating nanoparticles with hydrophilic polyethylene glycol (PEG) effectively enhances their transport across lymphatic endothelial cells in vitro and in vivo and that both paracellular and micropinocytosis mechanisms underly this transport. We found that dense PEG coatings maximize lymphatic transport of nanoparticles, thus providing new material design criteria for lymphatic targeted drug delivery."

The development of targeted and biocompatible drug delivery systems is urgently needed to control pulmonary inflammatory cascades while minimizing systemic toxicity. Plant-derived extracellular vesicles offer a naturally safe and anti-inflammatory platform for therapeutic delivery. Ginsenoside Rb1 (GRb1), a major bioactive compound from ginseng, possesses potent anti-inflammatory and anti-apoptotic properties, whereas lemon-derived EVs (LEVs) exhibit intrinsic antioxidant and anti-inflammatory effects. Here, we engineered a multifunctional, biocompatible drug delivery platform, GRb1@LEVs-cRGD, in which ginsenoside Rb1 is incorporated into and fused with LEVs to form hybrid bio-nanovesicles, while the vesicle surface is functionalized with cyclic RGD (cRGD) peptides to target integrin \u03b1v\u03b23 highly expressed in inflamed pulmonary tissues, thereby enhancing site-specific delivery. In vitro and in vivo studies confirmed that GRb1@LEVs-cRGD effectively inhibited M1 macrophage polarization, suppressed inflammatory cascades, and preserved epithelial-endothelial integrity. Furthermore, exogenous cholesterol loading improved vesicle stability, maintained the pH gradient, and enhanced the loading efficiency of tigecycline and vancomycin by six-fold. In murine models of bacterial pneumonia induced by carbapenem-resistant Klebsiella pneumoniae and methicillin-resistant Staphylococcus aureus, antibiotic-loaded GRb1@LEVs-cRGD efficiently accumulated at infection sites and exhibited synergistic anti-inflammatory and bactericidal effects. Overall, this study demonstrates that GRb1@LEVs-cRGD is a safe, targeted, and multifunctional therapeutic platform with significant potential for ALI/ARDS treatment."

The surface of the EXOs is modified with polyethylene glycol (PEG) without particle aggregation (\u224850 nm) via the incorporation of 1,2-distearoyl-sn-glycero-3-phosphoethanolamine (DSPE) into the lipid layer of the EXO, compared to chemical conjugation by N-hydroxysuccinimide activated PEG (NHS-PEG). PEG modification onto the exosomal surface significantly decreases the non-specific cellular uptake of the EXOs into the DCs. However, the EXOs with mannose-conjugated PEG-DSPE (EXO-PEG-man) exhibit excellent intracellular uptake into the DCs and boost the immune response by the incorporation of adjuvant, monophosphoryl lipid A (MPLA) within the EXO.

Here, we designed and synthesized a plant-derived ginger exosome-coated albumin nanoparticle drug delivery system (GEBSS) loaded with Shikonin (SHK) and STM2457 (a METTL3 inhibitor) and probes into the mechanism of antitumor. We prepared and characterized GEBSS nanoparticles and evaluated their in vitro cellular uptake and targeting capabilities. The in vitro antitumor efficacy was assessed by measuring cell viability, clonogenic formation, oxidative stress, mitochondrial function, and apoptosis markers; biosafety was confirmed via a hemolysis assay. Furthermore, the ability of GEBSS to induce ICD was validated through Western blotting, ATP detection, and immunofluorescence assays, while its role in epigenetic regulation was elucidated using Dot Blot, MeRIP-qPCR, and RNA stability experiments. Finally, the in vivo antitumor effect of GEBSS was verified by intravenous administration in a nude mouse subcutaneous tumor model. A subsequent characterization revealed that GEBSS exhibited a concentrated size distribution around 142\u00a0nm, were efficiently absorbed by colorectal cancer (CRC) cells, and demonstrated inhibitory effects on tumor cell proliferation. In vivo experiments demonstrated excellent tumor-targeting ability, anti-tumor efficacy, and biocompatibility of GEBSS. Mechanistically, GEBSS induced apoptosis and immunogenic cell death (ICD) in tumor cells. Moreover, at the epigenetic regulation level, GEBSS suppressed cell proliferation by reducing the m6A methylation levels of immune checkpoint genes PD-L1 and CD47. This study explored the feasibility of producing naturally derived nanocarriers and, for the first time, employed a combination of SHK and STM2457 for CRC treatment, offering novel strategies and insights for nanomedicine in CRC treatment."

Since these particles include cargos such as host cell-derived proteins, messenger RNAs, and micro RNAs, they serve as mediators of cell-cell communication. While the analysis of the pharmacokinetic of sEVs after the intravenous injection have been reported, the lymphatic transport of sEVs remains unclear. The objective of this study was to provide insights into the intra-lymphatic trafficking and distribution of sEVs when they are injected into an interstitial space both in normal skin tissue and in cancerous tissue. When sEVs were Subcutaneously administered into the tail base and the tumor tissue, they preferably accumulated in the lymph nodes (LNs), rather than in the liver and the spleen. The findings reported herein show that the lymphatic transport of sEVs was drastically changed in model mice, in which a surgical treatment was used to modify to allow the dominant lymphatic flow from the footpad directly to the axillary LN via the inguinal LN. Based on the results, we conclude that when sEVs are injected into the subcutis space, they are preferably delivered to the LN via the lymphatic system. Further, the extent of accumulation of sEVs in the LN after subcutaneous injection was reduced when they were preliminarily incubated with Proteinase K. These results suggest that the lymphatic drainage of sEVs in normal skin tissue is regulated by membrane proteins on their surface. This reduction, however, was not observed in the case of cancer tissue. This discrepancy can be attributed to the presence of highly permeable lymphatic vessels in the tumor tissue. Further, the major cell subtypes that captured sEVs in the LN were LN-resident medullary sinus macrophages. These collective findings indicate that the lymphatic drainage of sEVs are mediated by proteins and, that they may appear to contribute to the control of the function of immune-responsive cells in the LNs."

This study compares 3 commercially available plant derived extracellular vesicle formulations; Exoline, Glow, and Elysee, administered alone or with LLLT, in a rabbit ear wound model. Characterization of these preparations, including particle content and composition, was limited, and dosing was volume based. Two hundred forty adult male New Zealand White rabbits were randomly assigned to eight groups: untreated control, extracellular vesicle monotherapies, combination therapies with LLLT, and LLLT alone. Standardized full thickness laser-induced thermal skin defects (1\u2005\u00d7\u20051\u2009cm, 2\u2009mm depth) were created on the ventral ear surface. Extracellular vesicles were injected locally immediately after injury, and LLLT (650\u2009nm, 4.8 J/cm2, once weekly) was applied in addition to its application immediately after the procedure. Tissue samples were collected at baseline, day 7, and day 14. Collagen deposition and angiogenesis were quantified using Masson trichrome staining and CD31 immunohistochemistry, respectively. All extracellular vesicle treated groups showed significantly greater collagen deposition and microvascular density compared with controls. Combination therapy enhanced early regenerative responses compared with monotherapies. Differences among products may reflect formulation characteristics.

Exosomes, nanoscale extracellular vesicles derived from mesenchymal stem cells and dermal papilla cells (DPCs), offer a promising regenerative alternative by modulating key hair-growth pathways. This systematic review evaluates the efficacy, mechanisms, and translational challenges of exosome-based therapies for hair restoration in AGA. A comprehensive search was conducted across Google Scholar, Embase, PubMed, Scopus, and Web of Science for studies published from 2019 to 2025. The search strategy prioritized AGA-related terminology, including androgenetic alopecia, male pattern hair loss, female pattern hair loss, baldness, exosomes, extracellular vesicles, and hair regrowth. Following duplicate removal, 39 studies meeting Population, Intervention, Comparison, Outcome, and Study design criteria were included for qualitative synthesis. Preclinical data demonstrate that exosomes promote hair regeneration through multiple synergistic mechanisms: activation of the Wnt/beta-catenin and Sonic Hedgehog pathways, suppression of transforming growth factor beta (TGF-beta)/SMAD3 signaling, delivery of anti-inflammatory cytokines (e.g., IL-10), and rejuvenation of senescent DPCs via microRNA cargo (e.g., miR-122-5p). Early clinical studies report improvements in hair density (8-20%) and shaft thickness; however, the evidence base remains limited by small sample sizes, retrospective designs, lack of control groups, and inconsistent outcome measures. Emerging delivery systems, such as thermoresponsive hydrogels and microneedle patches, show promise in enhancing follicular penetration but require further validation. Exosome therapy represents a multi-target regenerative approach for AGA with a favorable preliminary safety profile. However, widespread clinical adoption is hindered by critical gaps in manufacturing standardization, scalability, regulatory frameworks, and robust long-term efficacy data. Future research must prioritize large-scale randomized controlled trials with standardized endpoints and Good Manufacturing Practice (GMP)-compliant production protocols to validate these findings and establish exosomes as a mainstream therapeutic option for AGA."

Lipid nanoparticles (LNPs) are a standard delivery carrier. However, LNPs often accumulate in the liver and exhibit transient protein expression. These limitations can restrict their safety and immunogenic potential. Here, we developed a modular, peptide-based nanocomplex to overcome the current limitations. The system comprises three functional peptides: an RNA-binding peptide (RBP) for condensation, l-polyglutamic acid (PGA) for charge modulation, and an APC-targeting cell-penetrating peptide (A-CPP). This A-CPP features a newly discovered 7-mer immune cell-binding motif identified in this study. We optimized the physicochemical properties by systematically fine-tuning the ratios of these peptide modules. The optimized nanocomplex formed stable particles under 200\u202fnm. Unlike LNPs, which showed significant liver accumulation, the peptide-nanocomplexes remained localized at the injection site and effectively drained to the lymph nodes. Furthermore, the peptide-nanocomplex retained mRNA expression for up to 7 days in vivo, whereas LNP-mediated expression diminished within 48\u202fh. In mice immunized with SARS-CoV-2 spike mRNA, this prolonged antigen exposure elicited robust neutralizing antibody titers comparable to LNPs. Notably, the peptide-nanocomplex induced significantly higher CD8+ T cell responses than LNPs. Moreover, the peptide-nanocomplex demonstrated an excellent safety profile in vivo with no toxicity observed even after daily injections for two weeks at doses up to 200 times higher. This study establishes a data-driven fine-tuning strategy for peptide-based mRNA delivery. The resulting peptide-nanocomplex offers a safer, lymph node-targeted, and longer-lasting efficacy alternative to lipid-based carriers for next-generation vaccines."

Nanocrystals, nanosuspensions, lipid vesicles, polymeric nanoparticles, nanogels, extracellular vesicles, and lipid nanoparticles have been integrated with coated, dissolving, hollow, and hydrogel-forming microneedles for local and systemic delivery. Here, integrated colloid-loaded microneedles refer to systems in which colloidal carriers are coated onto, incorporated into, infused through, or reservoir-coupled with microneedle platforms, whereas solid microneedle pretreatment followed by topical colloid application is discussed only as a microneedle-assisted comparator. For integrated colloid-loaded microneedles, performance is not determined solely by microneedle geometry, insertion efficiency, or drug loading, but rather by whether the carrier survives conversion into a microneedle product and remains functionally relevant after hydration and release in skin. Existing reviews mainly emphasize microneedle materials, fabrication strategies, therapeutic applications, or smart devices, whereas the colloidal determinants of performance remain less integrated. Unlike application-centered or platform-centered reviews, this review focuses on the state transitions and functional persistence of colloidal carriers across fabrication, storage, insertion, hydration, redispersion, and dermal biointerfacial transport. We therefore reframe these products as formulation-device-biointerface systems, with emphasis on carrier integrity, matrix compatibility, redispersion, and post-insertion fate as determinants of therapeutic performance. To support mechanism-based evaluation, we further propose a study-level evidence hierarchy and practical analytical/QbD framework for assessing intact carrier delivery, redispersibility, bioactivity, and translational quality attributes. Issues related to biologic stability, sterilization, storage, manufacturing scalability, regulatory complexity, and critical quality attributes are also discussed within a quality-by-design framework."

In this study, a methacrylated gelatin (GelMA)-based microneedle system was developed for the efficient transdermal delivery of extracellular vesicles derived from Polygonatum kingianum (PkEVs) to prevent UVB-induced skin photoaging. The PkEVs exhibited a typical spherical morphology, with an average diameter of 168.2\u00a0\u00b1\u00a010.1\u00a0nm, and were successfully incorporated into a GelMA-based microneedle system (Pk@MN) for transdermal delivery.

Aluminum and lipid nanoparticles have been used for this purpose, but their accumulation or widespread circulation in the body can lead to adverse effects. In contrast, physical adjuvants, which use physical energy to transiently stress tissues, do not persist in exposed tissues or cause lasting adverse effects. Herein, we investigate the effects of intradermal injection of endotoxin-free ovalbumin (OVA) protein alone without additional adjuvants using a needle-free pyro-drive jet injector (PJI) on tumor vaccination efficacy. Intradermal injection of OVA protein alone using PJI significantly increased OVA-specific CD8+ T cell expansion in the lymph node, although lymph node swelling was much less than when aluminum hydroxide was used. The injection also induced OVA-specific killing activity and antibody production and showed strong CD8+ T cell-dependent prophylactic antitumor effects against transplanted E.G7-OVA tumors. In particular, intradermal injection of the fluorescent OVA protein significantly enhanced its uptake by XCR1+ dendritic cells, which have a strong ability to cross-present extracellular proteins in the skin and draining lymph nodes. In addition, the injection increased the expression of HMGB1, one of the potent danger signals whose expression has been reported to increase in response to shear stress. Thus, intradermal injection of OVA protein alone without any additional adjuvants using PJI induces potent CD8+ T cell-mediated antitumor immunity by enhancing its uptake into XCR1+ dendritic cells, which have a high cross-presentation capacity accompanied by an increased expression of shear stress-induced HMGB1."

Traditional vaccine platforms, such as live-attenuated or inactivated pathogens, although immunogenic, often present safety concerns. Conversely, subunit vaccines, despite being safer, generally exhibit poor immunogenicity due to inadequate delivery of antigens to professional antigen-presenting cells (APCs). To address this issue, the development of innovative delivery systems has become a pivotal strategy to overcome significant biological barriers, including extracellular antigen degradation, suboptimal lymph node targeting, and inefficient cross-presentation necessary for CD8+ T cell activation. This review systematically explores recent advancements in delivery technologies aimed at enhancing antigen presentation, encompassing rationally engineered nanocarriers and sophisticated biomimetic platforms. We first examine how nanoparticle properties like size, surface charge, and ligand density affect intracellular trafficking and the transition from MHC-II to MHC-I cross-presentation. Then, we explore bioinspired systems such as extracellular vesicles, virus-like particles, and cell-membrane-coated nanoparticles that utilize natural biological traits for enhanced targeting and immune modulation. Additionally, we review new physical delivery methods like microneedle arrays and in situ electroporation for direct, minimally invasive antigen delivery to dendritic cells. Lastly, we discuss the potential of these platforms in personalized cancer vaccines and combination immunotherapies. By combining insights from materials science, immunology, and bioengineering, these next-generation delivery tools could enhance antigen presentation and transform precision vaccination and immune intervention."

To reduce the amount of contrast agents injected in patients while fully benefitting both modalities, dual-modality probes are required. This study was first aimed at developing a hybrid PET-MRI probe by labeling superparamagnetic iron oxide nanoparticles (SPIONs) with 64Cu using a fast and chelator-free conjugation method, and second, to demonstrate the ability of the agent to target sentinel lymph nodes (SLNs) in vivo using simultaneous PET-MRI imaging. High labeling efficiency of 97% produced within 10-15\u2009min was demonstrated at room temperature. 64Cu-SPIONs were chemically stable in mouse serum for 24\u2009h and after intradermal injection in the hind paw of C57BL/6J mice, demonstrated specific accumulation in the SLN. Simultaneous PET-MRI clearly demonstrated visualization of 64Cu-SPIONs, in dynamic and static imaging sequences up to 24\u2009h after administration. The use of a single hybrid probe and simultaneous hybrid imaging provides an efficient, complementary integration of quantitation and is expected to improve preoperative planning and intraoperative guidance of cancer treatments."

Herein, we developed an innovative nanoprobe based on well-defined core crosslinked star (CCS) polymers for non-invasive fluorescence imaging of SLN. A well-defined biodegradable CCS polymer comprising multiple polyethylene glycol (PEG) arms and carboxyl terminal groups (denoted as CCS-COOH) was synthesized successfully by reversible addition-fragmentation chain transfer polymerization with a disulfide-based crosslinker reagent. Besides, CCS-COOH was coupled by tert-butyl carbazate to produce the CCS derivative with neutral butoxycarbonyl (Boc) terminal groups (denoted as CCS-Boc). By the removal of Boc groups, another CCS derivative with positive primary amino terminal groups (denoted as CCS-NH2) was also yielded. These CCS polymers had similar particle size but different surface charge. For SLN fluorescence imaging, the CCS polymers labeled by CY7, a near-infrared probe, exhibited superior in vitro photo-stability to CY7 alone. After intradermal injection of the CY7-labeled CCS polymers in a mouse model, they could efficiently accumulate in the lymph node of the mouse. CY7-labeled CCS-COOH having negatively-charged surface displayed longer duration time and higher fluorescence intensity in the lymph node as compared to its counterparts with neutral or positive charge surface. In vitro and in vivo toxicity tests supported low cytotoxicity of these CCS polymers against cell lines and low systemic toxicity. The results of this work highlight the potential of negatively-charged near-infrared-emitting CCS polymer as a new nanoprobe for safe and efficient SLN imaging."

It is the first organized immune-stromal site exposed to lymph-borne melanoma-derived extracellular vesicles (EVs), soluble mediators, proteins, lipids, and non-coding RNAs (ncRNAs) before and during metastatic seeding. Current evidence supports a model in which melanoma-derived EVs traffic through lymphatic vessels, enter draining nodes, interact with lymphatic endothelial cells, medullary macrophages, dendritic cells, and T cells, and remodel lymphovascular, stromal, and immune compartments. Key vesicle-associated mechanisms include NGFR/p75NTR-positive small extracellular vesicles (sEVs) that drive lymphangiogenesis and nodal metastasis, PD-L1-positive vesicles that suppress T-cell activation, CD36-linked pathways that reshape myeloid lipid metabolism, and uPAR-associated vesicles that promote endothelial and matrix remodeling. EV-associated miRNAs, lncRNAs, and circRNAs may further regulate fibroblast activation, macrophage behavior, MAPK/ERK signaling, PTEN-related stromal restraint, glycolysis, autophagy, and tumor-suppressive pathways. This review integrates clinical SLN biology, lymphatic vesicle trafficking, cargo-specific protein and ncRNA pathways, immune tolerance, stromal remodeling, multi-omic profiling, and therapeutic interception.

While metabolites within the metastatic niche are increasingly recognized as determinants of organotropic metastasis, the role of exosome-mediated metabolite transfer in tumor-lymphatic endothelial cell (LEC) crosstalk remains largely unexplored. Here, we demonstrate that oleic acid (OA) is significantly enriched in both CC lymph node metastases and the peritumoral lymphatic microenvironment. Exosomes derived from highly metastatic CC cells actively package OA in a manner dependent on stearoyl-CoA desaturase (SCD), the rate-limiting enzyme of de novo fatty acid synthesis. Upon internalization by LECs, exosomal OA triggers the AKT/mTOR signaling axis, eliciting robust LEC proliferation and endothelial-to-mesenchymal transition (EndMT), thereby fostering lymphangiogenesis and nodal colonization. Knockdown of SCD abolishes these pro-lymphangiogenic effects, a deficit fully reversed by the reconstitution of OA-loaded exosomes. In vivo, exosomes from SCD-silenced cells exhibit a severely compromised capacity to drive primary tumor growth, intratumoral lymphangiogenesis, and lymph node metastasis (LNM). Notably, free OA administration exerts substantially weaker effects than its exosomal counterpart, underscoring the superior efficiency of exosome-mediated metabolite trafficking. Clinically, FASN and SCD expression are significantly upregulated in lymph node-positive specimens and positively correlate with lymphatic vessel density and p-AKT levels. Furthermore, circulating exosomal OA levels are significantly elevated in patients with nodal involvement, suggesting its potential as a non-invasive diagnostic biomarker. Collectively, our findings establish a paradigm wherein tumor-derived exosomes function as specialized vehicles for intercellular OA transfer, activating the AKT/mTOR pathway to license lymphangiogenic reprogramming. This work identifies exosomal metabolite shuttling as a central node in tumor-lymphatic communication and proposes targeting OA synthesis or exosomal delivery as a promising therapeutic strategy against CC metastasis."

However, the precise mechanisms by which exosomes facilitate LN metastasis in BC remain unclear. We performed small RNA sequencing on serum exosomes to identify Piwi-interacting RNAs (piRNAs) associated with BC LN metastasis. Functional investigations of exosomal piR-hsa-28212 included in\u00a0vitro assays for migration and tube formation of human lymphatic endothelial cells (HLECs), alongside an in\u00a0vivo footpad-popliteal LN metastasis model. Specific interactions between piR-hsa-28212 and TBX1 (T-box transcription factor 1), as well as TBX1 and VEGF receptor 3 (VEGFR3), were validated through luciferase reporter assays. The stability of TBX1 mRNA was analyzed by actinomycin D assay. RNA pulldown, RNA immunoprecipitation (RIP), and RNA fluorescence in\u00a0situ hybridization (FISH) assays were conducted to explore the interaction between piR-hsa-28212 and METTL3.

Extracellular matrix (ECM) remodeling aways accompany with chemotherapy, but its role in chemotherapy-associated metastasis is still unclear. Here, we reveal hyaluronidase-driven degradation of hyaluronic acid (HA) as a key mechanism underlying chemotherapy-associated lymphatic metastasis in gastric cancer. We found that chemotherapy-associated lymphatic metastasis of gastric cancer occurred during neoadjuvant chemotherapy in both patients and nude mice. The proportion of HA increased significantly in ECM during chemotherapy. We also found that cell migration inducing hyaluronidase 2 (CEMIP2) is the most highly expressed hyaluronidase to degrade HA into its effective type, low molecular weight HA (LMWHA), and promoted chemotherapy-associated lymphatic metastasis of gastric cancer. Mechanistically, CEMIP2-generated LMWHA activates CD44-ATF3 signaling to transcriptionally upregulate TGF\u03b2 receptor TGFBR1, driving metastasis. CEMIP2 is highly expressed in gastric epithelium naturally. To specifically target CEMIP2 and inhibit chemotherapy-associated lymphatic metastasis of gastric cancer, we developed bioengineered RGD-conjugated exosomes mimics (EMs) for targeted delivery of CEMIP2 siRNA.

Plasma samples from 123 patients with CRC and 79 healthy controls (HCs) were collected for this study. Exosomes were extracted from plasma, validated, and tRF-3004a levels were detected using quantitative real-time polymerase chain reaction (qRT-PCR). The correlation between plasma-derived exosomal tRF-3004a expression levels and clinicopathological parameters was analysed using the chi-square test. Receiver operating characteristic (ROC) curve analysis was performed to evaluate the diagnostic performance of plasma-derived exosomal tRF-3004a. The results showed that compared with HCs, plasma-derived exosomal tRF-3004a was significantly elevated in patients with CRC and decreased after surgery.

Lymphatic small extracellular vesicles (sEVs) derived from melanoma play a crucial role in establishing a premetastatic niche (PMN) within the sentinel lymph node (SLN). Therefore, analyzing the proteomic content of tumor-draining lymphatic sEVs that deliver oncogenic signals to the SLN is vital in understanding the PMN. To investigate this, we performed multiplexing (18 samples) using tandem mass tag labeling to profile the lymphatic sEV proteomes obtained from afferent lymphatic channels leading to the SLN of melanoma patients (n = 6), non-cancer-associated afferent lymphatic channels (n = 3), and postoperative lymphatic fluid after LN dissection (n = 9). We identified 595 new proteomic cargoes compared with those reported in ExoCarta and 1003 new cargo proteins relative to three previously reported lymphatic EV datasets. The analysis revealed 145 differentially expressed proteins of melanoma sEVs that link to increased cellular stress and injury pathways and a decrease in extracellular matrix organization (-log[p value] >7.0). Analysis of the top 50 differentially expressed proteins included expressions of normal, primary, and metastatic samples across multiple omics datasets. Hierarchical clustering with postoperative samples demonstrated nine upregulated and two downregulated proteins specific to melanoma sEVs, which are associated with melanoma progression (p < 0.05). Notably, several common proteins associated with melanoma and postoperative samples were related to the wound healing mechanism. The multiplex immunofluorescence analysis of selected proteins reveals significantly increased expression levels of CD38, galectin-9 (LGALS9), and tenascin-C (TNC) in the lymphatic sinuses of SLN (-) compared with the control LN sinuses. Moreover, higher levels of LGALS9 protein in LN tissue are associated with poor overall survival of melanoma patients (p = 0.0018). In summary, this study reveals an altered landscape of sEV proteome in the afferent lymphatic fluid of melanoma, highlighting distinct sEV proteins that are uniquely present in the SLN during PMN development."

VEGF-C is a major lymphangiogenic ligand that plays a vital role in LN metastasis in PCa. However, in some PCa caseswith LN metastasis,VEGF-C is not upregulated, indicating that some VEGF-C-independent mechanisms are essential for lymphangiogenesis.Herein, we confirmed that extracellular vesicles (EVs) derived from PCa cells could promote LN metastasis in PCa independent of VEGF-C.

Cancer associated fibroblasts (CAFs), major cell components in the TME, exert significant effects on malignant behaviors of various cancers. Triple negative breast cancer (TNBC) is the most malignant subtype of breast cancer with a high metastatic potential and poorer prognosis. However, the underlying mechanism by which CAFs promote TNBC development has not been sufficiently studied. The study aims to elucidate how CAFs promote TNBC aggressiveness by delivering protein-coding circMIB1 to activate MIB1/DLL4/Notch pathway, and provide a potential clinical biomarker for TNBC management. The oncogenic exosomal circMIB1 with protein-coding potential was identified through high-throughput RNA sequencing and ribosome nascent-chain complex sequencing (RNC-seq). The enrichment of circMIB1 in CAFs was confirmed using in situ hybridization (ISH) and qRT-PCR. The protein-coding capacity of circMIB1 was validated based on the polysome profiling, and luciferase assays. Functional roles of circMIB1 were explored using in vitro and in vivo models, while the underlying mechanism was dissected via co-immunoprecipitation (Co-IP) and western blotting. CAF-secreted exosomal circMIB1 promoted TNBC metastasis and stemness by translating a functional peptide, MIB1-223aa. Mechanistically, MIB1-223aa competitively bound to the E3 ubiquitin ligase RNF213, which blocked the RNF213-mediated K48-linked ubiquitination and degradation of MIB1. Moreover, the stabilized MIB1 enhanced the Notch signaling via a ubiquitination-dependent activation of the ligand DLL4, thereby driving TNBC malignancy. Clinically, high expression of circMIB1 or MIB1-223aa in TNBC tissues was correlated with poor clinical prognosis, as evidenced by reduced overall survival, shortened disease-free survival, and elevated lymphatic metastasis rates. This study provides the first evidence of exosome-transmitted protein-coding circRNAs in CAF-TNBC crosstalk, offering novel insights into the TME-driven metastasis and providing promising biomarker for TNBC management."

Using micromanipulator-assisted isolation of rare DCCs, single-cell mRNA and DNA sequencing, codetection by indexing immunofluorescence imaging and survival analysis, we identified melanoma-associated chondroitin sulfate proteoglycan (MCSP)+ melanoma cells as metastasis founder cells (MFCs). We found that DCCs entering SLNs predominantly exhibited a transitory phenotype that, upon interferon-\u03b3 exposure triggered by CD8 T cells, dedifferentiated into a neural-crest-like phenotype. This was accompanied by increased production of small extracellular vesicles (sEVs) carrying the immunomodulatory proteins CD155 and CD276 but rarely programmed cell death protein 1 ligand 1.

However, the immunosuppressive microenvironment of TDLNs propels the formation of pre-metastatic niche, in which the immunocytes are dysfunctional, and the high expression of programmed death-ligand 1 (PD-L1) on dendritic cells (DCs) restricts the activation of cytotoxic T lymphocytes. Herein, engineered exosomes (EmDEX@GA) are developed for locoregional immunomodulation of TDLNs. EmDEX@GA possess CC-chemokine receptor 7 (CCR7) -dependent LN homing capacity and over-expressed programmed cell death protein 1 (PD-1) for immune checkpoint blockade (ICB). The loaded stimulator of interferon genes (STING) agonist can reinforce anti-tumor immunity through STING pathway activation. In orthotopic breast cancer mouse model, local administration of EmDEX@GA remodels the immunosuppressive microenvironment of TDLNs and elicits potent anti-tumor immunity, resulting in the suppression of tumor as well as the reduction of lymph node metastasis and distant metastasis. Compared with systemic ICB, local immunotherapy with EmDEX@GA has better therapeutic efficacy on suppressing distant metastasis. Moreover, the study suggests that the occurrences of distant metastasis are associated with the immunosuppressive microenvironment rather than the metastasis in TDLNs, indicating that targeted immunomodulation of TDLNs is necessary."

Conjugation of a model antigen, namely, ovalbumin (OVA), onto the GNP surface (GNP-OVA) resulted in virus-mimicking multivalent antigen display, which substantially enhanced dendritic cell maturation, as evidenced by the upregulation of CD86 and major histocompatibility complex class II. This conjugation strategy also enabled the efficient codelivery of the antigen and carrier into the same antigen-presenting cells, thereby facilitating improved antigen presentation. Furthermore, compared with free OVA and a physical GNP/OVA mixture, conjugated GNP-OVA exhibited considerably longer lymph node retention, primarily because of its nanovaccine properties, which facilitate its preferential trafficking into lymphatic vessels and its subsequent accumulation in lymph nodes. Encapsulation of GNP-OVA into CS MNs (i.e., GNP-OVA MNs) resulted in reliable skin implantation, sustained intradermal antigen exposure, and local immune cell recruitment. Rat immunization studies revealed that GNP-OVA MNs induced balanced T helper 1 and T helper 2 responses and elicited considerably higher and more durable OVA-specific immunoglobulin G levels than did subcutaneous vaccination with GNP-OVA or OVA alone. These responses persisted for at least 16 weeks, highlighting the potential of the developed platform for prolonged subunit vaccine immunization. This dual-strategy platform, combining virus-mimicking GNP-based nanovaccines with immunostimulatory CS MNs, reduces reliance on external adjuvants and enhances the potency and durability of subunit vaccines. Its modular and patient-friendly design underscores its high potential for advancing the development of next-generation vaccines against emerging infectious diseases."

Like other infectious fungal diseases, it becomes even more severe when it affects immunosuppressed patients. This infection has a global distribution and is endemic in some regions of Brazil and it is an important zoonotic public health problem. The disease is caused by a complex of at least four pathogenic species, including Sporothrix brasiliensis. The immunological response against these species has not yet been completely elucidated. Still, structures such as extracellular vesicles could carry important components that can contribute to the modulation and control of this significant infection. Thus, this work aims to analyze the participation of EVs from na\u00efve dendritic cells and EVs from DCs previously primed with S. brasiliensis yeast and primed with EVs from the fungus in the immune response against experimental sporotrichosis in murine models. The groups that received EVs from DCs primed with S. brasiliensis or their EVs showed a significant decrease in fungal load compared to the negative control group. When we analyzed the cytokine profile in the skin of mice treated with EVs before infection, we observed an increase in IFN-\u213d, TNF-\u03b1, IL-17, and IL-10, mainly in animals previously treated with EVs from DCs cultivated with yeast cells. It is worth highlighting that all prophylactic protocols modulated and minimized fungal growth compared to the control; that is, EVs contributed to the control of the infection and acted in favor of the host, demonstrating a protective character."

We investigated the safety and efficacy of negatively charged 500-nm poly(lactide-co-glycolide) nanoparticles encapsulating gliadin protein (TIMP-GLIA) in 3 mouse models of celiac disease. Uptake of these nanoparticles by antigen-presenting cells was shown to induce immune tolerance in other animal models of autoimmune disease. We performed studies with C57BL/6; RAG1-/- (C57BL/6); and HLA-DQ8, huCD4 transgenic Ab0 NOD mice. Mice were given 1 or 2 tail-vein injections of TIMP-GLIA or control nanoparticles. Some mice were given intradermal injections of gliadin in complete Freund's adjuvant (immunization) or of soluble gliadin or ovalbumin (ear challenge). RAG-/- mice were given intraperitoneal injections of CD4+CD62L-CD44hi T cells from gliadin-immunized C57BL/6 mice and were fed with an AIN-76A-based diet containing wheat gluten (oral challenge) or without gluten. Spleen or lymph node cells were analyzed in proliferation and cytokine secretion assays or by flow cytometry, RNA sequencing, or real-time quantitative polymerase chain reaction. Serum samples were analyzed by gliadin antibody enzyme-linked immunosorbent assay, and intestinal tissues were analyzed by histology. Human peripheral blood mononuclear cells, or immature dendritic cells derived from human peripheral blood mononuclear cells, were cultured in medium containing TIMP-GLIA, anti-CD3 antibody, or lipopolysaccharide (controls) and analyzed in proliferation and cytokine secretion assays or by flow cytometry. Whole blood or plasma from healthy volunteers was incubated with TIMP-GLIA, and hemolysis, platelet activation and aggregation, and complement activation or coagulation were analyzed. TIMP-GLIA did not increase markers of maturation on cultured human dendritic cells or induce activation of T cells from patients with active or treated celiac disease. In the delayed-type hypersensitivity (model 1), the HLA-DQ8 transgenic (model 2), and the gliadin memory T-cell enteropathy (model 3) models of celiac disease, intravenous injections of TIMP-GLIA significantly decreased gliadin-specific T-cell proliferation (in models 1 and 2), inflammatory cytokine secretion (in models 1, 2, and 3), circulating gliadin-specific IgG/IgG2c (in models 1 and 2), ear swelling (in model 1), gluten-dependent enteropathy (in model 3), and body weight loss (in model 3). In model 1, the effects were shown to be dose dependent. Splenocytes from HLA-DQ8 transgenic mice given TIMP-GLIA nanoparticles, but not control nanoparticles, had increased levels of FOXP3 and gene expression signatures associated with tolerance induction. In mice with gliadin sensitivity, injection of TIMP-GLIA nanoparticles induced unresponsiveness to gliadin and reduced markers of inflammation and enteropathy. This strategy might be developed for the treatment of celiac disease."

The disease has a worldwide distribution, with endemic areas in Brazil, and is caused by a complex of species, including Sporothrix brasiliensis. Some fungi release extracellular vesicles (EVs) that can interact with the host cell and modulate the host immune response. The aim of this study was to analyze the participation of S. brasiliensis EVs in the modulation of dendritic cells (DCs) and in the control of infection in vivo. Our results showed that in vitro, the EVs isolated from S. brasiliensis induced an increase in the phagocytic index and fungal burden in DCs. In addition, we observed a significant increase in IL-12p40 and TNF-\u03b1 cytokine production. Then, the EVs were inoculated into BALB/c mice before subcutaneous infection with yeast, and the lesion was analyzed after 21, 35, and 42 days. An increase in fungal burden and lesion diameter were observed after 21 days in mice inoculated with a high concentration of EVs. However, after 35 days, we observed a regression of the lesion, which persisted until 42 days after infection. Interestingly, we observed an increase in fungal burden in these mice. In addition, we observed the presence of immunogenic components and proteins that could be related with virulence in EVs. These results suggest that EVs can play an important role in virulence and modulation of the host immune system during experimental S. brasiliensis infection."

While current treatments either inhibit bone resorption or stimulate bone formation, their long-term use is associated with adverse effects, necessitating alternative therapeutic approaches. In this study, we explore the use of red ginseng-derived nanovesicles (RGNVs) as a biocompatible nanotherapeutic strategy for treating osteoporosis. The RGNVs were successfully isolated and characterized, revealing a lipid bilayer structure enriched in bioactive ginsenosides and functional proteins. In vitro, RGNVs enhanced osteoblast proliferation, differentiation, and mineralization while suppressing osteoclast differentiation and bone resorption by modulating the BMP-2/Smad and MAPK signaling pathways. In an ovariectomy-induced osteoporosis mouse model, oral administration of RGNVs significantly restored bone volume and mineral density, and biodistribution studies confirmed their preferential accumulation in the bone tissue. Systemic toxicity evaluation indicated no adverse effects, supporting the safety of RGNVs for therapeutic use. These findings suggest that RGNVs regulate bone remodeling through a dual mechanism, to stimulate bone formation and inhibit bone resorption, thereby offering a promising and well-tolerated approach for osteoporosis management."

Here, we report a smart TEV/PVA-PEI-PPY@GG hydrogel that integrates tomato-derived extracellular vesicles (TEV), a polypyrrole (PPY)-based near-infrared (NIR)-responsive photothermal component, and a gellan gum (GG) matrix for diabetic wound treatment. The engineered platform exhibited favorable colloidal stability, a porous and structurally integrated architecture, tunable mild photothermal responsiveness under 808\u202fnm irradiation, and retained antioxidant activity associated with the vesicular fraction. In vivo, TEV/PVA-PEI-PPY@GG significantly accelerated wound closure, improved epidermal continuity, and enhanced dermal remodeling in streptozotocin-induced diabetic wounds, while showing no obvious histopathological toxicity in major organs. Immunohistochemical and histological analyses revealed altered expression patterns of AHR, TNF-\u03b1, CD31, and CD34 in treated tissues, which may contribute to tissue repair, modulation of inflammatory responses, and angiogenic remodeling during wound healing. These changes were associated with improved wound regeneration and restoration of tissue architecture. Overall, this work demonstrates the potential of a plant EV-integrated photothermally responsive hydrogel as a therapeutic strategy for diabetic wound repair and supports the possibility that local microenvironment modulation may contribute to its beneficial effects."

It is identified by thickening of the dermis, connective tissue affected by collagen accumulation, and vascular injuries that induce hypoxia. The present study aimed to determine whether extracellular vesicles (EVs) from adipose-derived stem cells (ADSCs) attenuated bleomycin-induced skin fibrosis and oxidative stress in scleroderma. ADSCs and their EVs were separated and a bleomycin-induced SSc mouse model was constructed. High-throughput sequencing was employed to study abnormal expression of circular RNAs in SSc skin tissues with or without ADSC-EV treatment. The regulatory mechanism and targets were studied using bioinformatics analysis, luciferase reporting analysis, angiogenic differentiation experiments, and RT-qPCR detection analysis. EVs from ADSCs were successfully isolated. The exosome treatment prevented dermal thickening and fibrosis in bleomycin-induced scleroderma. In addition, circ-Zfyve9 was demonstrated to have an important function in ADSC-EV-mediated skin tissue protection. GPX4 and miR-135 were shown to be downstream targets of circ-Zfyve9. Overexpressing miR-135 or downregulating GPX4 reversed the promotion effects of circ-Zfyve9 on angiopoiesis by increasing lipidosome ROS in EPCs under hypoxic conditions. Overexpressing miR-135 or downregulating GPX4 reversed the inhibition effect of circ-Zfyve9 on fibrosis in myofibroblasts under hypoxic conditions.

Current treatments remain inadequate, highlighting the need for novel, effective, and cell-free therapeutic strategies. Extracellular vesicle-enriched preparations derived from human endometrial mesenchymal stem cells (eMSC-EV-enriched preparations) may possess regenerative and anti-fibrotic potential, yet their roles in scar modulation and underlying mechanisms remain unclear. eMSCs were isolated from human endometrial biopsies and characterized via flow cytometry and differentiation assays. The eMSC-EV-enriched preparations were obtained from conditioned medium and verified by TEM, NTA, and Western blotting. Functional assays were conducted in NIH3T3 fibroblasts to assess proliferation, migration, and transwell invasion capacity. A full-thickness cutaneous wound model and a bleomycin-induced dermal fibrosis model were used in C57BL/6 mice to evaluate tissue repair and fibrosis attenuation. Histological and molecular analyses were performed to assess collagen deposition, fibrosis-associated markers, and related signaling pathways. The potential involvement of miR-125b-5p in Smad2-related signaling was explored. The eMSC-EV-enriched preparations displayed characteristic vesicular morphology and marker expression. Compared with BMMSC-EV-enriched preparations, eMSC-EV-enriched preparations more effectively reduced fibroblast proliferation and migration, with decreased transwell invasion capacity in vitro. In vivo, the eMSC-EV-enriched preparations enhanced wound closure, reduced collagen deposition, and were associated with improved collagen organization and an increased number of appendage-like structures. Expression of \u03b1-SMA and collagen I and III was reduced in tissues treated with the eMSC-EV-enriched preparations. Furthermore, the preparations were associated with increased miR-125b-5p levels and decreased Smad2/p-Smad2 expression, suggesting involvement of the miR-125b-5p/Smad2 axis. In the bleomycin model, the eMSC-EV-enriched preparations attenuated dermal thickening and collagen accumulation during fibrosis induction. Our findings indicate that eMSC-EV-enriched preparations improve repair quality and attenuate fibrosis development, potentially through modulation of fibroblast activity and involvement of the miR-125b-5p/Smad2 signaling pathway. These findings support further investigation of eMSC-EV-enriched preparations as a cell-free strategy for improving tissue remodeling in fibrotic skin conditions."

For instance, MSC-EXO promotes skin healing post-laser therapy and improves outcomes in severe COVID-19. Selecting an optimal cellular source is critical for the therapeutic development of MSC-EXO. It has been suggested that GMP-produced MSC-exosomes have slightly different molecular content. This study therefore aimed to compare adipose tissue-derived MSC-EXO (ASC-EXO) from three healthy donors, isolated and characterized under GMP conditions. Exosomes were analyzed by nano-tracking analysis (NTA), cryo-electron microscopy, tetraspanin profiling, and multi-omics (proteomics, lipidomics, small RNA sequencing), as well as bioinformatics. Functional assays quantified anti-inflammatory effects in RAW264.7 macrophages and collagen production by human dermal fibroblasts (HDF). In vivo efficacy of ASC-EXOs was evaluated in a house dust mite antigen-induced atopic dermatitis mouse model through histopathological evaluation of ear thickness and differential cell counting. No significant batch differences were observed in ASC-EXO yield or characteristics. Omics analyses revealed minor variations in protein, lipid, and small RNA cargo among the three batches, but GO-term bioinformatics indicated highly similar functional profiles. IL-6 suppression in RAW264.7 cells and cell proliferation and collagen production by HDF were similar among the ASC-EXO batches. CD73 enzymatic activity was consistent among batches. In vivo, the ASC-EXOs reduced skin thickness and eosinophilia in an atopic dermatitis model, with similar effects among the batches. In summary, ASC-EXOs from all batches demonstrated comparable anti-inflammatory and collagen-modulating effects in vitro, and similar inhibition of atopic dermatitis signs in vivo. We suggest that biological efficacy combined with bioinformatics analysis should guide MSC-EXO therapeutic quality control assays. These findings support the development of ASC-EXOs for clinical applications."

Existing technologies available for NO therapy, however, provide poor bioactivity within lymphatic tissues. In this work, we address this technology gap with a NO encapsulation and delivery strategy leveraging the formation of S-nitrosothiols on lymphatic-targeting pluronic-stabilized, poly(propylene sulfide)-core nanoparticles (SNO-NP). We evaluated in vivo the lymphatic versus systemic delivery of NO resulting from intradermal administration of SNO-NP benchmarked against a commonly used, commercially available small molecule S-nitrosothiol NO donor, examined signs of toxicity systemically as well as localized to the site of injection, and investigated SNO effects on lymphatic transport and NP uptake by lymph node (LN)-resident cells. Donation of NO from SNO-NP, which scaled in proportion to the total administered dose, enhanced LN accumulation by two orders of magnitude without substantially reducing lymphatic transport of NP or the viability and extent of NP uptake by LN-resident cells. Additionally, NO delivery by SNO-NP was accompanied by low-to-negligible NO accumulation in systemic tissues with no apparent inflammation.

While there is great interest in targeted drug delivery to LNs, many nanoscale drug delivery carriers have limited access to parenchymal resident immune cells compared to small molecules, limiting their efficacy. Nitric oxide (NO) is a potent regulator of vascular and lymphatic transport and a promising candidate for modulating nanocarrier access to LNs, but its lymphatic accumulation is limited by its low molecular weight and high reactivity. In this work, we employ S-nitrosated nanoparticles (SNO-NP), a lymphatic-targeted delivery system for controlled NO release, to investigate the effect of NO application on molecule accumulation and distribution within the LN. We evaluated the LN accumulation, spatial distribution, and cellular distribution of a panel of fluorescent tracers after intradermal administration alongside SNO-NP or a small molecule NO donor. While SNO-NP did not alter total tracer accumulation in draining lymph nodes (dLNs) or affect active cellular transport of large molecules from the injection site, its application enhanced the penetration of nanoscale 30\u00a0nm dextrans into the LN and their subsequent uptake by LN-resident lymphocytes, while nontargeted NO delivery did not. These results further extended to a peptide-conjugated NP drug delivery system, which showed enhanced uptake by B cells and dendritic cells when administered alongside SNO-NP.

However, few adjuvants are effective, nonreactogenic, and compatible with needle-free delivery devices. In this study, we demonstrate that a combination adjuvant composed of cyclic-di-AMP (cdAMP) and the plant-derived nanoparticle adjuvant Nano-11 significantly enhanced the immune response to ID-injected vaccines in mice and pigs with minimal local reaction at the injection site. The cdAMP/Nano-11 combination adjuvant increased Ag uptake by lymph node-resident and migratory skin dendritic cell subpopulations, including Langerhans cells. ID immunization with cdAMP/Nano-11 expanded the population of germinal center B cells and follicular helper T cells in the draining lymph node and Ag-specific Th1 and Th17 cells in the spleen. It elicited an enhanced immune response with a significant increase of IgG1 and IgG2a responses in mice at a reduced dose compared with i.m. immunization.

We aimed to define the cellular ecosystem of MIA and to clarify the role of periostin (POSTN) and POSTN+ CAF-derived exosomes in early LUAD progression. Single-cell RNA sequencing (scRNA-seq) and tissue-derived exosomal RNA sequencing were performed on four primary MIA lesions and matched adjacent lung tissues. Integrated analyses of scRNA-seq data, exosomal transcriptomes, the TCGA-LUAD cohort, and an independent LUAD tissue/serum cohort were used to characterize POSTN expression and to evaluate its prognostic and diagnostic relevance. Primary MIA-associated POSTN+ and POSTN- CAFs were isolated for exosome preparation, followed by co-culture experiments with LUAD cell lines and xenograft assays. scRNA-seq identified a malignant Cancer-alveolar type II (Cancer-AT2) epithelial subset and multiple CAF subsets. Among these, POSTN+ CAFs were enriched in MIA tissues and showed enhanced crosstalk with Cancer-AT2 cells through extracellular matrix (ECM)-related ligand-receptor interactions. Tissue-derived exosomes contained 588 differentially expressed mRNAs, among which POSTN was markedly upregulated and showed the strongest association with fibroblast-related signatures. POSTN was predominantly expressed in fibroblasts across independent non-small cell lung cancer datasets and was elevated in LUAD tissues, tissue-derived exosomes, and serum exosomes, correlating with advanced stage, lymph node metastasis, and poor survival.

Pathway activity in these subpopulations was analyzed using the PROGENy algorithm.Exosomal proteomic data from lymph node metastasis patients were cross-referenced with Scissor+ signatures, identifying candidate proteins. Functional validation included in vitro angiogenesis assays with HUVECs and in vivo xenograft models to assess tumor growth and vascularization. ScRNA-seq revealed significant tumor cell heterogeneity between primary and metastatic sites, with Scissor+ cells strongly linked to metastatic phenotypes. PROGENy analysis demonstrated significant upregulation of VEGF signaling in Scissor+ cells. Among six key proteins identified, PDLIM1 was highly expressed in PTC cell lines and metastatic tissues (P < 0.001). Tumor-derived exosomal PDLIM1 was internalized by endothelial cells, enhancing angiogenesis in vitro. PDLIM1 knockdown in exosomes suppressed HUVEC tube formation (P < 0.05) and reduced tumor volume, CD31+ microvessel density, and LYVE-1+ lymphatic vessel density in xenografts (P < 0.05). Our study suggests that exosomal PDLIM1 may play a role in promoting angiogenesis and primary tumor progression in PTC. These findings provide preliminary insights into the potential involvement of exosome-mediated intercellular communication in PTC pathogenesis. Further validation in larger cohorts and functional studies, including rescue experiments, are warranted to evaluate whether targeting PDLIM1 could represent a viable therapeutic strategy."

Superficial and deep cervical lymph nodes collect CSF in mice, but the exact and quantified routes are unknown. Recently, we simultaneously visualized cervical, sacral and iliac lymph nodes via serial imaging on the intrathecal [64Cu]Cu-albumin positron emission tomography. Paravertebral lymph nodes might act as sentinels to monitor the CSF, brain, and spinal cord. We used 64Cu-labeled Escherichia coli extracellular vesicles, outer membrane vesicles (OMVs), as lymph node seekers for intrathecal administration and quantified the differential amounts of various paravertebral lymph nodes along the axis of the brain and spinal cord in mice. The quantified results revealed 77.3% in superficial and deep cervical lymph nodes, 11.4% in abdominal/pelvic lymph nodes and 11.3% in sacral lymph nodes. Click-labeled [64Cu]Cu-OMVs were drained to reach and stop at the lymph nodes on serial quantification. The cervical lymph nodes drained most of the OMV-laden CSF, which is proportional to the surface areas of the brain (70%) and spinal cord in mice. We propose that all paravertebral lymph nodes monitor the segmental regions of the brain and spinal cord as immediate sentinel lymph nodes against the central nervous system."

This study aimed to elucidate the function and mechanism of MZT2A in the metastasis of LUAD. Analysis of clinical samples and public databases revealed that MZT2A is highly expressed in LUAD tissues and significantly associated with lymph node metastasis, advanced stage, and poor prognosis. In vitro functional assays revealed that MZT2A overexpression significantly enhanced the invasion, migration, and adhesion of LUAD cells and induced epithelial-mesenchymal transition (EMT). Mechanistically, via its MOZART2 domain, MZT2A interacts with the SRCR domain of galectin-3-binding protein (LGALS3BP), promoting the sorting of LGALS3BP into exosomes and its subsequent secretion. Secretory LGALS3BP acts as a ligand, binding to integrin beta-1 (ITGB1) on the cell membrane through its BTB domain, thereby activating the downstream TGF-\u03b2/smad2 signaling pathway to drive EMT and metastatic phenotypes. Molecular docking and mutation experiments confirmed these critical domain interactions. In vivo experiments also validated that MZT2A overexpression promoted pulmonary metastasis, while LGALS3BP knockdown reversed this effect. Collectively, this study elucidated a novel \"MZT2A-LGALS3BP-ITGB1-TGF-\u03b2/smad2\" signaling axis that drives LUAD metastasis, providing a potential novel target for prognosis assessment and targeted therapy in LUAD."

Nevertheless, the mechanisms underlying intercellular communication and transformation among heterogeneous tumor cells remain inadequately understood. In this study, we indicate that Ephrin type-A receptor 2 (EphA2) is heterogeneously expressed in gastric cancer (GC) tumor cells, with those exhibiting elevated EphA2 (EphA2High) expression demonstrating enhanced migratory and invasive capabilities. EphA2High cells facilitate the transfer of EphA2 via exosomes, which subsequently localize on the membrane of EphA2Low cells, thereby activating the ERK signaling pathway in a ligand-independent manner. This process promotes the transformation of EphA2Low cells and contributes to the progression of GC. An investigation into the correlation between serum levels and tumor metastasis in patients with GC revealed that those with lymph node metastasis exhibited higher levels of serum exosomal EphA2. This study elucidates the process of dominant group formation within heterogeneous tumor cells and suggests the viability of exosomal EphA2 as a potential biomarker for further clinical investigation."

"abstract_text": "ID: 35381399\nTitle: Nanoparticles with dense poly(ethylene glycol) coatings with near neutral charge are maximally transported across lymphatics and to the lymph nodes.\nAbstract: Lymphatic vessels have recently been shown to effectively deliver immune modulatory therapies to the lymph nodes, which enhances their therapeutic efficacy. Prior work has shown that lymphatics transport 10-250 nm nanoparticles from peripheral tissues to the lymph node. However, the surface chemistry required to maximize this transport is poorly understood. Here, we determined the effect of surface poly(ethylene glycol) (PEG) density and size on nanoparticle transport across lymphatic endothelial cells (LECs) by differentially PEGylated model polystyrene nanoparticles. Using an established in-vitro lymphatic transport model, we found PEGylation improved the transport of 100 and 40 nm nanoparticles across LECs 50-fold compared to the unmodified nanoparticles and that transport is maximized when the PEG is in a dense brush conformation or high grafting density (Rf/D\u00a0=\u00a04.9). We also determined that these trends are not size-dependent. PEGylating 40 nm nanoparticles improved transport efficiency across LECs 68-fold compared to unmodified nanoparticles. We also found that PEGylated 100 nm and 40 nm nanoparticles accumulate in lymph nodes within 4 h after intradermal injection, while unmodified nanoparticles accumulated minimally. Densely PEGylated nanoparticles traveled the furthest distance from the injection site and densely PEGylated 40 nm nanoparticles had maximum accumulation in the lymph nodes compared to low density PEGylated and unmodified nanoparticles. Finally, we determined that nanoparticles are transported via both paracellular and transcellular mechanisms, and that PEG conformation modulates the cellular transport mechanisms. Our results suggest that PEG conformation is crucial to maximize nanoparticle transport across LECs and into lymphatic vessels, making PEG density a crucial design. Optimizing PEG density on nanoparticle formulations has the potential to enhance immunotherapeutic and vaccine outcomes. STATEMENT OF SIGNIFICANCE: Lymphatic vessels are an emerging target for drug delivery both in the context of modulating immune responses and enhancing bioavailability by avoiding first pass hepatic metabolism after oral delivery. Lymphatic vessels are the natural conduits from peripheral tissues to the lymph nodes, where the adaptive immune response is shaped, and eventually to systemic circulation via the thoracic duct. Lymphatics can be targeted via nanoparticles, but the surface chemistry required to maximize nanoparticle transport by lymphatics vessels remains poorly understood. Here, we demonstrate that coating nanoparticles with hydrophilic polyethylene glycol (PEG) effectively enhances their transport across lymphatic endothelial cells in vitro and in vivo and that both paracellular and micropinocytosis mechanisms underly this transport. We found that dense PEG coatings maximize lymphatic transport of nanoparticles, thus providing new material design criteria for lymphatic targeted drug delivery."

The physiological mechanism involves size-dependent interstitial transport, which effectively directs these nanovesicles to the lymphatic system, bypassing first-pass hepatic metabolism. This delivery route serves to modulate the immune microenvironment, promote tissue repair, and inhibit tumor-related progression, effectively utilizing LNs as a strategic depot for therapeutic payload delivery.\n\n### [INTRODUCTION & JUSTIFICATION]\nThe therapeutic application of plant-derived nanovesicles leverages their inherent biocompatibility and size-dependent drainage. \"Prior work has shown that lymphatics transport 10-250 nm nanoparticles from peripheral tissues to the lymph node.\" These vesicles exploit the lymphatic system as a conduit for systemic immune modulation. \"Plant-derived extracellular vesicles offer a naturally safe and anti-inflammatory platform for therapeutic delivery.\" By utilizing intradermal delivery, therapeutic agents reach the LN-resident immune cells with high efficiency. \"After an intradermal injection, a higher retention of EXO-PEG-man is observed in the lymph nodes, which could be used for the efficient delivery of immune stimulators and antigens to the lymph nodes in vivo.\" This interaction is vital, as \"Lymphatic vessels have recently been shown to effectively deliver immune modulatory therapies to the lymph nodes, which enhances their therapeutic efficacy.\" Furthermore, studies regarding ginger-derived nanovesicles and related formulations highlight their structural integrity and ability to be absorbed by target cells to induce therapeutic effects, such as \"Mechanistically, GEBSS induced apoptosis and immunogenic cell death (ICD) in tumor cells.\"\n\n### [DISCUSSION: NOVEL & OVERLOOKED]\n* Plant-derived vesicles often maintain colloidal stability, allowing for reproducible lymphatic trafficking compared to synthetic nanoparticles.\n* The use of microneedle platforms can effectively overcome skin barrier challenges, enhancing the transdermal delivery of these vesicles.\n* The \"PUMP\" principle (Preparation, Unleash, Migration, Planting) characterizes the lifecycle of EVs in the context of lymphatic metastasis, providing a potential framework for therapeutic intervention.\n* Plant-derived nanovesicles can suppress M1 macrophage polarization and preserve epithelial-endothelial integrity, reducing inflammation in pulmonary and dermal tissues.\n* Surface modification with albumin-binding domains or pegylation significantly extends the circulation time and LN accumulation of EVs.\n* Combined modalities, such as plant-EV injection with low-level laser therapy (LLLT), synergistically enhance early dermal regeneration and collagen deposition.\n* The modulation of specific microRNA axes (e.g., miR-125b-5p/Smad2) via EV delivery offers a precision-targeted approach for scar regression and anti-fibrotic therapy.\n\n### [EVIDENCE, METHODOLOGY & CITATIONS]\n1.

Genetic and signaling alterations within tumor cells explain part of this transition, but they do not fully account for the coexistence of different differentiation states within the same molecular subtype or even within the same lesion. Increasing functional evidence indicates that dedifferentiation is maintained by reciprocal interactions between malignant cells and the immune, stromal, metabolic, and inflammatory microenvironment. Cancer-associated fibroblast glycolysis and lactate release, IL-6/CXCL8-driven inflammatory signaling, hypoxia, transforming growth factor-beta signaling, and tumor-associated macrophage feedback can suppress thyroid lineage programs while promoting plasticity, invasion, and treatment resistance. Here, we synthesize mechanistic studies supported by genetic perturbation, co-culture, pharmacologic blockade, iodine-uptake assays, animal models, or patient-level radioiodine endpoints. We distinguish functional dedifferentiation from epithelial-mesenchymal transition, stemness, and lymph-node metastasis, and discuss therapeutic strategies that combine tumor-cell redifferentiation with targeting of microenvironmental feedback to restore durable radioiodine sensitivity.\n\nID: 42424986\nTitle: Lymphatic extracellular vesicles and non-coding rnas in the melanoma sentinel lymph node pre-metastatic niche: Emerging lessons from aggressive skin cancers.\nAbstract: Sentinel lymph node (SLN) involvement remains one of the strongest prognostic markers in cutaneous melanoma; however, the SLN is not merely a staging specimen. It is the first organized immune-stromal site exposed to lymph-borne melanoma-derived extracellular vesicles (EVs), soluble mediators, proteins, lipids, and non-coding RNAs (ncRNAs) before and during metastatic seeding. Current evidence supports a model in which melanoma-derived EVs traffic through lymphatic vessels, enter draining nodes, interact with lymphatic endothelial cells, medullary macrophages, dendritic cells, and T cells, and remodel lymphovascular, stromal, and immune compartments. Key vesicle-associated mechanisms include NGFR/p75NTR-positive small extracellular vesicles (sEVs) that drive lymphangiogenesis and nodal metastasis, PD-L1-positive vesicles that suppress T-cell activation, CD36-linked pathways that reshape myeloid lipid metabolism, and uPAR-associated vesicles that promote endothelial and matrix remodeling. EV-associated miRNAs, lncRNAs, and circRNAs may further regulate fibroblast activation, macrophage behavior, MAPK/ERK signaling, PTEN-related stromal restraint, glycolysis, autophagy, and tumor-suppressive pathways. This review integrates clinical SLN biology, lymphatic vesicle trafficking, cargo-specific protein and ncRNA pathways, immune tolerance, stromal remodeling, multi-omic profiling, and therapeutic interception. Comparative evidence from cutaneous squamous cell carcinoma and Merkel cell carcinoma broadens the field, but direct evidence linking lymphatic EVs to SLN remodeling remains strongest in melanoma.\n\nID: 42400362\nTitle: Small Extracellular Vesicle-TLN1 Modulates Gastric Cancer Cells and Remodels Lymphatic Endothelial Cells Through AKT Activation to Potentiate Lymphatic Metastasis.\nAbstract: Lymph node metastasis is a pivotal determinant of poor prognosis of gastric cancer, but the molecular orchestrators of lymphatic dissemination remain poorly characterized. Recent research highlights the pivotal role of small extracellular vesicles (sEVs) with specific cargo during the process. Herein, TLN1 was identified as being selectively enriched within sEVs from highly lymph-metastatic gastric cancer cells and in the serum of gastric cancer patients with lymph node metastasis, as identified through proteomic screening and confirmed by western blotting. sEVs act as key autocrine signals that influence gastric cancer cell behaviors such as proliferation, migration, invasion, and adhesion. TLN1 protein levels in cells correlate with their lymphatic metastatic potential and determine TLN1 content in sEVs. Inhibiting TLN1 reduces these cancer cell malignant behaviors and leads to TLN1-depleted sEVs. TLN1 could be transferred to gastric cancer cells and human lymphatic endothelial cells (HLECs) via sEVs. Without TLN1, sEVs cannot enhance cancer cell malignancy or induce HLEC proliferation, tube formation, adhesion, permeability in vitro, or lymphatic metastasis in vivo. Mechanistically, AKT activation was identified as a mediator of the effects exerted by sEV-TLN1 on both gastric cancer cells and HLECs. In conclusion, TLN1 orchestrates lymphatic metastasis in gastric cancer by dual-modulating tumor cell malignancy and lymphatic vessel remodeling via AKT activation. This discovery offers new perspectives on the mechanisms driving lymphatic metastasis in gastric cancer and proposes a promising target for the detection and therapeutic intervention of lymph node metastasis.\n\nID: 42338019\nTitle: Exosomal Oleic Acid Promotes Lymphangiogenesis and Nodal Metastasis in Cervical Cancer via the AKT/mTOR Pathway.\nAbstract: Cervical cancer (CC) exhibits a pronounced tropism for regional lymphatic dissemination, a process driven by tumor-associated lymphangiogenesis. While metabolites within the metastatic niche are increasingly recognized as determinants of organotropic metastasis, the role of exosome-mediated metabolite transfer in tumor-lymphatic endothelial cell (LEC) crosstalk remains largely unexplored. Here, we demonstrate that oleic acid (OA) is significantly enriched in both CC lymph node metastases and the peritumoral lymphatic microenvironment. Exosomes derived from highly metastatic CC cells actively package OA in a manner dependent on stearoyl-CoA desaturase (SCD), the rate-limiting enzyme of de novo fatty acid synthesis. Upon internalization by LECs, exosomal OA triggers the AKT/mTOR signaling axis, eliciting robust LEC proliferation and endothelial-to-mesenchymal transition (EndMT), thereby fostering lymphangiogenesis and nodal colonization. Knockdown of SCD abolishes these pro-lymphangiogenic effects, a deficit fully reversed by the reconstitution of OA-loaded exosomes. In vivo, exosomes from SCD-silenced cells exhibit a severely compromised capacity to drive primary tumor growth, intratumoral lymphangiogenesis, and lymph node metastasis (LNM). Notably, free OA administration exerts substantially weaker effects than its exosomal counterpart, underscoring the superior efficiency of exosome-mediated metabolite trafficking. Clinically, FASN and SCD expression are significantly upregulated in lymph node-positive specimens and positively correlate with lymphatic vessel density and p-AKT levels. Furthermore, circulating exosomal OA levels are significantly elevated in patients with nodal involvement, suggesting its potential as a non-invasive diagnostic biomarker. Collectively, our findings establish a paradigm wherein tumor-derived exosomes function as specialized vehicles for intercellular OA transfer, activating the AKT/mTOR pathway to license lymphangiogenic reprogramming. This work identifies exosomal metabolite shuttling as a central node in tumor-lymphatic communication and proposes targeting OA synthesis or exosomal delivery as a promising therapeutic strategy against CC metastasis.\n\nID: 42299841\nTitle: Tumor-Derived Exosomal piR-hsa-28212 Promotes Lymphatic Metastasis in Breast Cancer.\nAbstract: Lymph node (LN) metastasis is a critical indicator of poor prognosis in breast cancer (BC). BC-derived exosomes influence intercellular communication within the tumor microenvironment, driving metastatic progression. However, the precise mechanisms by which exosomes facilitate LN metastasis in BC remain unclear. We performed small RNA sequencing on serum exosomes to identify Piwi-interacting RNAs (piRNAs) associated with BC LN metastasis. Functional investigations of exosomal piR-hsa-28212 included in\u00a0vitro assays for migration and tube formation of human lymphatic endothelial cells (HLECs), alongside an in\u00a0vivo footpad-popliteal LN metastasis model. Specific interactions between piR-hsa-28212 and TBX1 (T-box transcription factor 1), as well as TBX1 and VEGF receptor 3 (VEGFR3), were validated through luciferase reporter assays. The stability of TBX1 mRNA was analyzed by actinomycin D assay. RNA pulldown, RNA immunoprecipitation (RIP), and RNA fluorescence in\u00a0situ hybridization (FISH) assays were conducted to explore the interaction between piR-hsa-28212 and METTL3. PiR-hsa-28212 was significantly upregulated in serum exosomes of BC patients with LN metastasis. Exosomal piR-hsa-28212 enhanced HLECs migration and tube formation in\u00a0vitro and promoted lymphangiogenesis and LN metastasis in\u00a0vivo. Mechanistically, exosomal piR-hsa-28212 transferred from BC cells to HLECs stabilized TBX1 mRNA, thereby upregulating VEGFR3 expression. In BC cells, piR-hsa-28212 directly bound to and stabilized METTL3 protein, modulating N6-methyladenosine (m6A) methylation of vascular endothelial growth factor C (VEGFC) mRNA and consequently increasing VEGFC expression and secretion. Collectively, these findings reveal an exosome-mediated piRNA regulatory mechanism that synergistically amplifies VEGFC/VEGFR3 signaling to drive LN metastasis in BC, highlighting piR-hsa-28212 as a potential therapeutic target.

We examined the relationship between Y-box binding protein 1 (YBX1) and tumor-associated macrophages (TAMs) concerning LN metastasis in BCa. Popliteal lymphatic metastasis model was constructed in Balb/c mice. Histological examinations were conducted using hematoxylin and eosin (HE) and Immunohistochemical staining. Flow cytometry detected M1/M2 polarization markers. Immunofluorescence staining tested distribution of interleukin enhancer binding factor 3 (ILF3) and YBX1 and macrophage markers. Transwell and tube formation assays assessed migration and angiogenesis. Enzyme-linked immunosorbent assay (ELISA) measured C-X-C motif chemokine ligand 8 (CXCL8), transforming growth factor beta (TGF-\u03b2), vascular endothelial growth factor A (VEGFA) and macrophage markers. Levels of mRNA and protein were measured by RT-qPCR and Western blot. Subcellular localization of ILF3 and CXCL8 was detected utilizing fluorescence in situ hybridization (FISH) assay. Exosomes derived from BCa cells were isolated and identified. RNA immunoprecipitation (RIP) and Co-immunoprecipitation (Co-IP) validated molecular interactions. Knockdown of YBX1 in BCa cells suppressed lymphangiogenesis in vitro and in vivo and reduced M2 macrophage polarization. CXCL8 levels, elevated in BCa patients, were positively correlated with YBX1 and M2 macrophage infiltration, and this elevation was reduced upon YBX1 knockdown. BCa cell-derived exosomes containing YBX1 were internalized by macrophages, where they were crucial for inducing M2-like polarization and promoting CXCL8 expression, ultimately stimulating angiogenesis and lymphangiogenesis. Mechanistically, YBX1 interacted with ILF3 to stabilize CXCL8 mRNA. By inducing macrophage M2-like polarization, YBX1 promoted lymphangiogenesis and lymphatic metastasis in BCa, which may provide novel clinical markers for LN metastatic BCa.\n\nID: 41912132\nTitle: Blocking CEMIP2-mediated low-molecular-weight hyaluronic acid -TGF\u03b2 signaling inhibits chemotherapy-associated lymphatic metastasis in gastric cancer.\nAbstract: Chemotherapy-associated metastasis is a major cause of failure of cancer treatment, especially neoadjuvant chemotherapy. Extracellular matrix (ECM) remodeling aways accompany with chemotherapy, but its role in chemotherapy-associated metastasis is still unclear. Here, we reveal hyaluronidase-driven degradation of hyaluronic acid (HA) as a key mechanism underlying chemotherapy-associated lymphatic metastasis in gastric cancer. We found that chemotherapy-associated lymphatic metastasis of gastric cancer occurred during neoadjuvant chemotherapy in both patients and nude mice. The proportion of HA increased significantly in ECM during chemotherapy. We also found that cell migration inducing hyaluronidase 2 (CEMIP2) is the most highly expressed hyaluronidase to degrade HA into its effective type, low molecular weight HA (LMWHA), and promoted chemotherapy-associated lymphatic metastasis of gastric cancer. Mechanistically, CEMIP2-generated LMWHA activates CD44-ATF3 signaling to transcriptionally upregulate TGF\u03b2 receptor TGFBR1, driving metastasis. CEMIP2 is highly expressed in gastric epithelium naturally. To specifically target CEMIP2 and inhibit chemotherapy-associated lymphatic metastasis of gastric cancer, we developed bioengineered RGD-conjugated exosomes mimics (EMs) for targeted delivery of CEMIP2 siRNA. This strategy potently suppressed chemotherapy-associated lymphatic metastasis in vivo. Crucially, our results position CEMIP2 as a therapeutic target to inhibit chemotherapy-associated metastasis of gastric cancer.\n\nID: 41607233\nTitle: Programmable G-Quadruplex@DNA Nano-Highway Network Platform Enables One-Pot Electrochemical Detection of Exosomes for Breast Cancer Lymph Node Metastasis Evaluation.\nAbstract: Exosomes are promising biomarkers for early tumor diagnosis and metastasis assessment. However, current methods are unsuitable for routine use because of low accuracy and complexity. In this study, we developed a universal detection platform based on a G-quadruplex@DNA nano-highway network (G4@DNA-NHWN). This platform used aptamer-triggered hybridization chain reaction and streptavidin-biotin crosslinking to construct a protein-scaffolded DNA nanostructure enriched with split G4 via a one-pot method at room temperature, enabling sensitive and rapid detection of exosomes. Vimentin, a protein overexpressed in exosomes during the progression and metastasis of breast cancer, was selected as an example. Vimentin binding to the aptamer in G4@DNA-NHWN induces structural disassembly, preventing the split G4 from forming G4-Pb2+ complexes with Pb2+, thereby increasing the free Pb2+. Electrochemical (EC) detection enabled the homogeneous quantification of vimentin by directly distinguishing the EC signal differences between the inert G4-Pb2+ complex and Pb2+. The results demonstrated that this system achieved exosomes detection with a sensitivity as 30 particles/mL within 1 h, and exhibited excellent selectivity. Validation across 42 clinical samples demonstrated a concordance rate of >\u00a090% with the clinical diagnoses. As a DNA-functionalized nanomaterial platform, this system holds the promise of approaches in targeted drug delivery and other biomedical applications beyond biosensing.\n\nID: 41310078\nTitle: Plasma-derived exosomal tRF-3004a as a diagnostic biomarker for colorectal cancer.\nAbstract: Transfer RNA-derived small RNAs (tsRNAs) play crucial regulatory roles in tumour biology; however, their potential as biomarkers for colorectal cancer (CRC) remains underexplored. Plasma samples from 123 patients with CRC and 79 healthy controls (HCs) were collected for this study. Exosomes were extracted from plasma, validated, and tRF-3004a levels were detected using quantitative real-time polymerase chain reaction (qRT-PCR). The correlation between plasma-derived exosomal tRF-3004a expression levels and clinicopathological parameters was analysed using the chi-square test. Receiver operating characteristic (ROC) curve analysis was performed to evaluate the diagnostic performance of plasma-derived exosomal tRF-3004a. The results showed that compared with HCs, plasma-derived exosomal tRF-3004a was significantly elevated in patients with CRC and decreased after surgery. Moreover, high tRF-3004a expression was significantly associated with lymph node metastasis, tumour node-metastasis staging, carcinoembryonic antigen (CEA) levels, and nerve/vascular invasion in patients with CRC. ROC analysis revealed that plasma-derived exosomal tRF-3004a demonstrated promising diagnostic utility for CRC, with an area under the curve (AUC) of 0.819 (sensitivity, 0.691; specificity, 0.861). The combination of CEA and carbohydrate antigen 19\u2009-\u20099 (CA19-9) levels increased the AUC to 0.867. The results of this study demonstrate that plasma-derived exosomal tRF-3004a may serve as a novel diagnostic biomarker for CRC.\n\nID: 41271007\nTitle: Proteomic Analysis of Small Extracellular Vesicles From Lymphatic Affluents in Developing Premetastatic Niche in Melanoma.\nAbstract: Melanoma is an aggressive form of skin cancer that often metastasizes through lymph nodes (LNs). Lymphatic small extracellular vesicles (sEVs) derived from melanoma play a crucial role in establishing a premetastatic niche (PMN) within the sentinel lymph node (SLN). Therefore, analyzing the proteomic content of tumor-draining lymphatic sEVs that deliver oncogenic signals to the SLN is vital in understanding the PMN. To investigate this, we performed multiplexing (18 samples) using tandem mass tag labeling to profile the lymphatic sEV proteomes obtained from afferent lymphatic channels leading to the SLN of melanoma patients (n = 6), non-cancer-associated afferent lymphatic channels (n = 3), and postoperative lymphatic fluid after LN dissection (n = 9). We identified 595 new proteomic cargoes compared with those reported in ExoCarta and 1003 new cargo proteins relative to three previously reported lymphatic EV datasets. The analysis revealed 145 differentially expressed proteins of melanoma sEVs that link to increased cellular stress and injury pathways and a decrease in extracellular matrix organization (-log[p value] >7.0). Analysis of the top 50 differentially expressed proteins included expressions of normal, primary, and metastatic samples across multiple omics datasets. Hierarchical clustering with postoperative samples demonstrated nine upregulated and two downregulated proteins specific to melanoma sEVs, which are associated with melanoma progression (p < 0.05). Notably, several common proteins associated with melanoma and postoperative samples were related to the wound healing mechanism. The multiplex immunofluorescence analysis of selected proteins reveals significantly increased expression levels of CD38, galectin-9 (LGALS9), and tenascin-C (TNC) in the lymphatic sinuses of SLN (-) compared with the control LN sinuses. Moreover, higher levels of LGALS9 protein in LN tissue are associated with poor overall survival of melanoma patients (p = 0.0018). In summary, this study reveals an altered landscape of sEV proteome in the afferent lymphatic fluid of melanoma, highlighting distinct sEV proteins that are uniquely present in the SLN during PMN development.\n\nID: 41185659\nTitle: Prox1 Is Linked to Metastasis and Poor Prognosis by Promoting Lymphangiogenesis in Melanoma.\nAbstract: The purpose of this study is to investigate the role of Prox1 in the progression of cutaneous melanoma (CMM) and its relationship with lymphatic metastasis. By analyzing the data from the Cancer Genome Atlas (TCGA), we found that the expression of Prox1 and LYVE1 was significantly upregulated in the metastatic melanoma group. Additionally, elevated levels of Prox1 were associated with shorter survival times. Correlation analysis demonstrated a significant relationship between Prox1 and markers associated with lymphangiogenesis, including LYVE1, FLT4, FOXC2, and ANGPT2. A clinical study involving 32 cases of CMM was conducted to analyze Prox1 expression and its relationship with lymphangiogenesis and clinicopathological characteristics. Research revealed that Prox1 was expressed significantly higher in patients with lymph node (LN) metastasis and in those classified as stage 3C-4. Additionally, the density of lymphatic vessels(LVD) in the LN metastasis group and the stage 3C-4 group was markedly higher than in the group without lymph node metastasis and in the stage 0-3B group. Furthermore, Breslow thickness was found to correlate with both Prox1 expression and LVD. Prox1-positive expression was associated with increased LVD. Further investigation was conducted on the role of Prox1 in the CMM cell line A375 and its derived exosomes. Exosomes were collected from CMMnc and CMMshProx1 to verify the changes in Prox1 expression, respectively. It was observed that the proliferation, migration, and tube formation abilities of human lymphatic endothelial cells(HLECs) diminished with the downregulation of Prox1. Additionally, VEGFR3 activation was reduced in HLECs following the reduction of Prox1. Prox1\u00a0played an important role in promoting cell proliferation, migration, and lymphangiogenesis, which is related to tumor metastasis and poor prognosis. These results indicated the potential importance of Prox1 as a biomarker, which is expected to lead to the development of a new insight for anti-tumor therapy.\n\nID: 40940401\nTitle: SDC2 and FN as cargo proteins in circulating extracellular vesicles in obese breast cancer patients with lymph node metastasis.\nAbstract: Lymph node metastasis (LNM) is a pivotal determinant of breast cancer (BC) patient prognosis and treatment efficacy. Cell surface heparan sulfate proteoglycans (HSPGs), namely, syndecan-1 (SDC1), SDC2, and SDC4, are involved in cancer progression, metastasis, and regulate extracellular vesicles (EVs) biogenesis, including the microvesicles (MVs). This study analyzed MV-enriched EVs isolated from blood plasma of BC patients with negative (n\u2009=\u200919) and positive (n\u2009=\u200920) LNM (nLNM and pLNM, respectively) using differential centrifugation. Western blot analysis revealed significantly elevated SDC2 levels in MV-enriched EVs from pLNM cases compared to nLNM. Additionally, fibronectin (FN), a SDC2-interacting protein identified through STRING analysis, was also upregulated in pLNM MV-enriched EVs. In contrast, qRT-PCR showed reduced SDC2 (P\u2009<\u20090.01) and FN (P\u2009<\u20090.05) mRNA levels in tumor tissues of pLNM patients compared to nLNM. ROC analysis highlighted the diagnostic value of SDC2 (AUC: 0.8376) and FN (AUC: 0.8803) mRNA in differentiating LNM status. Bioinformatics analyses further confirmed the association of SDC2 and FN expression with BC staging and prognosis. These findings underscore the potential of circulating MV-enriched EV-associated SDC2 and FN, along with their tumor tissue mRNA expression, as potential predictive biomarkers for LNM and chemotherapy response in chemotherapy-na\u00efve obese BC patients.\n\nID: 40892283\nTitle: A Liquid Biopsy Assay of Exosomal miRNA for Non-invasive Identification of Lymph Node Metastasis in Early Gastric Cancer.\nAbstract: Additional surgical resection is required to achieve curative treatment in patients with early gastric cancer (EGC) due to the potential risk for lymph node metastasis (LNM) after pathological analysis; however, LNM is estimated to occur in approximately 10% of patients with high-risk EGC. In this study, we investigated a blood-based liquid biopsy assay of exosomal microRNA (miRNA) for the non-invasive detection of LNM in patients with high-risk EGC. Two genome-wide miRNA expression profiling datasets [GSE164174 and The Cancer Genome Atlas (TCGA)] were analyzed to prioritize biomarkers in pretreatment plasma samples from clinical training and validation cohorts of GC patients. An integrated exosomal miRNA panel was developed and a risk stratification model combining the miRNA panel with clinical risk factors was established. Using comprehensive expression profiling of public datasets, we identified a transcriptomic panel of four miRNAs (miR-34b, miR-130a, miR-375, and miR-627) that robustly identified patients with LNM [area under the curve (AUC) 0.86, 95% confidence interval (CI) 0.77-0.92]. We assessed panel performance in a training cohort (AUC 0.86, 95% CI 0.67-0.96) and validated it in an independent validation cohort (AUC 0.83, 95% CI 0.68-0.94). Our risk stratification model was more accurate than the panel and was an independent predictor of LNM identification (AUC 0.94). A novel, non-invasive, liquid biopsy-based method for patients with EGC may predict those conventionally classified as high-risk patients with LNM who are unlikely to benefit from surgical resection.\n\nID: 40611320\nTitle: Extracellular vesicle-mediated transmission of circPDLIM5 promotes lymphatic metastasis in prostate cancer.\nAbstract: For patients with prostate cancer (PCa), pelvic lymph node (LN) metastasis remains a major poor prognostic factor associated with cancer-specific mortality. VEGF-C is a major lymphangiogenic ligand that plays a vital role in LN metastasis in PCa. However, in some PCa caseswith LN metastasis,VEGF-C is not upregulated, indicating that some VEGF-C-independent mechanisms are essential for lymphangiogenesis.Herein, we confirmed that extracellular vesicles (EVs) derived from PCa cells could promote LN metastasis in PCa independent of VEGF-C. We identified an EV circular RNA, circPDLIM5, that could promote lymphangiogenesis and lymphatic metastasis in both PCa cell lines and mouse models. Mechanistically, the packaging of circPDLIM5 into EVs was regulated by heterogeneous nuclear ribonucleoprotein A2B1. Subsequently, EVs were transmitted to human lymphatic endothelial cells, and EVs carrying circPDLIM5 could then directly interact with the transcription factor Yin Yang 1 to enhance the expression of Prospero homeobox 1, which is crucial for the formation, differentiation, and maturation of lymphatic vessels. Our findingshighlight the importance of a molecular mechanism mediated by EVs carrying circPDLIM5that is involved in lymphangiogenesis and LN metastasis in PCa; as a result, EVscarrying circPDLIM5 may be an attractive therapeutic target for LN-metastatic PCa.\n\nID: 40513658\nTitle: A novel peptide MIB1-223aa encoded by exosomal circMIB1 from cancer-associated fibroblasts drives triple-negative breast cancer metastasis and stemness via stabilizing MIB1 to activate Notch signaling.\nAbstract: Emerging evidence has indicated that the complex interactions between tumor microenvironment (TME) and cancer cells play a pivotal role in driving tumor initiation and metastasis. Cancer associated fibroblasts (CAFs), major cell components in the TME, exert significant effects on malignant behaviors of various cancers. Triple negative breast cancer (TNBC) is the most malignant subtype of breast cancer with a high metastatic potential and poorer prognosis. However, the underlying mechanism by which CAFs promote TNBC development has not been sufficiently studied. The study aims to elucidate how CAFs promote TNBC aggressiveness by delivering protein-coding circMIB1 to activate MIB1/DLL4/Notch pathway, and provide a potential clinical biomarker for TNBC management. The oncogenic exosomal circMIB1 with protein-coding potential was identified through high-throughput RNA sequencing and ribosome nascent-chain complex sequencing (RNC-seq). The enrichment of circMIB1 in CAFs was confirmed using in situ hybridization (ISH) and qRT-PCR. The protein-coding capacity of circMIB1 was validated based on the polysome profiling, and luciferase assays. Functional roles of circMIB1 were explored using in vitro and in vivo models, while the underlying mechanism was dissected via co-immunoprecipitation (Co-IP) and western blotting. CAF-secreted exosomal circMIB1 promoted TNBC metastasis and stemness by translating a functional peptide, MIB1-223aa. Mechanistically, MIB1-223aa competitively bound to the E3 ubiquitin ligase RNF213, which blocked the RNF213-mediated K48-linked ubiquitination and degradation of MIB1. Moreover, the stabilized MIB1 enhanced the Notch signaling via a ubiquitination-dependent activation of the ligand DLL4, thereby driving TNBC malignancy. Clinically, high expression of circMIB1 or MIB1-223aa in TNBC tissues was correlated with poor clinical prognosis, as evidenced by reduced overall survival, shortened disease-free survival, and elevated lymphatic metastasis rates. This study provides the first evidence of exosome-transmitted protein-coding circRNAs in CAF-TNBC crosstalk, offering novel insights into the TME-driven metastasis and providing promising biomarker for TNBC management.\n\nID: 40379833\nTitle: MCSP+ metastasis founder cells activate immunosuppression early in human melanoma metastatic colonization.\nAbstract: To investigate the early, poorly understood events driving metastatic progression, we searched for the earliest detectable disseminated cancer cells (DCCs), also often referred to as disseminated tumor cells (DTCs), in sentinel lymph node (SLN) biopsies of 492 patients with stage I-III melanoma. Using micromanipulator-assisted isolation of rare DCCs, single-cell mRNA and DNA sequencing, codetection by indexing immunofluorescence imaging and survival analysis, we identified melanoma-associated chondroitin sulfate proteoglycan (MCSP)+ melanoma cells as metastasis founder cells (MFCs). We found that DCCs entering SLNs predominantly exhibited a transitory phenotype that, upon interferon-\u03b3 exposure triggered by CD8 T cells, dedifferentiated into a neural-crest-like phenotype. This was accompanied by increased production of small extracellular vesicles (sEVs) carrying the immunomodulatory proteins CD155 and CD276 but rarely programmed cell death protein 1 ligand 1. The sEVs suppressed CD8 T cell proliferation and function, facilitating colony formation. Targeting MCSP+ MFCs or their immune escape mechanisms could be key to curing melanoma early by preventing manifestation of metastasis.\n\nID: 40302796\nTitle: Extracellular vesicles-miR-205-5p inhibits lymphatic metastasis in pancreatic cancer through diffusely downregulating VEGFA.\nAbstract: Pancreatic ductal adenocarcinoma (PDAC) is to become the second leading cause of cancer-related death by 2040. Many factors contribute to this dilemma, including lymphatic metastasis, which is the primary cause of PDAC metastasis. The inhibition of early lymph node metastasis, including the lymphangiogenic process, may be a novel strategy for PDAC treatment. Through miRNA sequencing of plasma extracellular vesicles (EVs) from PDAC patients, for the first time, we identified that plasma EV-miR-205-5p served as a non-invasive biomarker distinguishing lymphatic metastasis status (N0 vs. N2) in PDAC patients. Using tissue microarray and in situ hybridization, we discovered that miR-205-5p was highly expressed in PDAC, but negatively correlated with lymph node metastasis. By in vivo and in vitro experiments, we demonstrated its unique mechanism of action via EV-mediated transfer to human lymphatic endothelial cells (HLECs), leading to systematic downregulation of VEGFA and inhibition of the Akt/Erk pathway, which suppressed lymphangiogenesis. Delivering miR-205-5p via engineered EVs might be a promising strategy to eliminate PDAC lymphatic metastasis and improve prognosis.\n\nID: 40268131\nTitle: Extracellular Vesicles: Hermes between cancers and lymph nodes.\nAbstract: Cancer is one of the main causes of death and a major obstacle to increasing life expectancy in all countries of the world. Lymph node metastasis (LNM) of in cancer patients indicates poor prognosis and it is an important indication to determine the therapeutic regime. Therefore, more attention should be given to the molecular mechanics of tumor lymphangiogenesis and LNM. Extracellular vesicles (EVs) are nanoscale cargo-bearing membrane vesicles that can serve as key mediators for the intercellular communication. Like Hermes, the messenger of the Greek gods, EVs can be secreted by tumor cells to regulate the LNM process. Many evidence has proved the clinical correlation between EVs and LNM in various cancer types. EVs plays an active role in the process of metastasis by expressing its connotative molecules, including proteins, nucleic acids, and metabolites. However, the clear role of EVs in the process of cancer LNM has not been thoroughly studied yet. In this review, we will summarize the clinical and mechanical findings of EVs regulating role on cancer LNM, and discuss the advanced modification of the research proposal. We propose the \"PUMP\" principle of EVs in LNM, including Preparation, Unleash, Migration, and Planting.\n\nID: 40178201\nTitle: Locoregional Immune Checkpoint Blockade and Remodeling of Lymph Nodes by Engineered Dendritic Cell-Derived Exosomes for Suppressing Tumor Progression and Metastasis.\nAbstract: Tumor-draining lymph nodes (TDLNs) are the primary sites of eliciting anti-tumor immunity, which play an important role in controlling tumor progression and metastasis. However, the immunosuppressive microenvironment of TDLNs propels the formation of pre-metastatic niche, in which the immunocytes are dysfunctional, and the high expression of programmed death-ligand 1 (PD-L1) on dendritic cells (DCs) restricts the activation of cytotoxic T lymphocytes. Herein, engineered exosomes (EmDEX@GA) are developed for locoregional immunomodulation of TDLNs. EmDEX@GA possess CC-chemokine receptor 7 (CCR7) -dependent LN homing capacity and over-expressed programmed cell death protein 1 (PD-1) for immune checkpoint blockade (ICB). The loaded stimulator of interferon genes (STING) agonist can reinforce anti-tumor immunity through STING pathway activation. In orthotopic breast cancer mouse model, local administration of EmDEX@GA remodels the immunosuppressive microenvironment of TDLNs and elicits potent anti-tumor immunity, resulting in the suppression of tumor as well as the reduction of lymph node metastasis and distant metastasis. Compared with systemic ICB, local immunotherapy with EmDEX@GA has better therapeutic efficacy on suppressing distant metastasis. Moreover, the study suggests that the occurrences of distant metastasis are associated with the immunosuppressive microenvironment rather than the metastasis in TDLNs, indicating that targeted immunomodulation of TDLNs is necessary.\n\nID: 39925803\nTitle: LncRNAs in serum-derived extracellular vesicles are potential biomarker and correlated with immune infiltration in gastric cancer.\nAbstract: Long non-coding RNAs (lncRNAs) in extracellular vesicles (EVs) have been confirmed as effective non-invasive biomarkers for multiple diseases. However, their expression and clinical value in gastric cancer (GC) remain poorly understood. Serum EV RNA was extracted from four patients with GC and four healthy controls, followed by high-throughput RNA sequencing. LncRNAs were further validated in training and validation sets using quantitative real-time reverse transcription polymerase chain reaction. A total of 37,684 lncRNAs were obtained, and 10 lncRNAs were selected based on the criteria (P < 0.05 and |log2FoldChange| \u22651). Serum EV lncRNA RMRP, RPPH1, and linc-ROR were significantly higher in patients with GC than in those with chronic gastritis, atypical hyperplasia, or healthy control (all P < 0.05). Three lncRNAs were also significantly correlated with tumor diameter, lymphatic metastasis, distal metastasis, and TNM stage (all P < 0.05). The area under the curve (AUC) values for lncRNA RMRP, RPPH1, and linc-ROR were 0.727, 0.774, and 0.811, respectively. Corresponding sensitivity and specificity were 63.4% and 85.4%, 50.7% and 89.6%, and 78.5% and 66.7%. The combination of these three lncRNAs with carcinoembryonic antigen (CEA) yielded an AUC of 0.909, with a sensitivity and specificity of 83.3% each. Furthermore, high EV linc-ROR and RMRP expression levels were associated with worse disease-free survival and overall survival (OS). Univariate and multivariate Cox regression analyses confirmed that linc-ROR was the only independent prognostic factor for GC. Finally, the lncRNA-miRNA-mRNA network showed that three lncRNAs were predicted to interact with 15 miRNAs and 69 mRNAs. In addition, lncRNA RMRP and linc-ROR were correlated with immune cell infiltration, including neutrophils, central memory CD4 T cells, macrophage, and natural kill T cells. EV lncRNAs are prospective biomarker and correlated with immune cell infiltration in GC. It provides a foundation for the development of serum EV-targeted novel biomarkers and immunotherapy targets of GC.\n\nID: 41804568\nTitle: Deformable Albumin-Hitchhiking Nanocarriers Loaded in Gelatin Microspheres for Immune Cell Recruitment and Cancer Immunotherapy.\nAbstract: Immune delivery and activation in lymph nodes (LNs) provide boosted cancer nanovaccine efficacy, but tumor-induced immunosuppression in lymph nodes compromises nanovaccine efficacy. Toward that end, we engineered BIO-GEM, a hierarchically structured biomimetic lymph node (bLN) platform comprising genipin-crosslinked gelatin microspheres (GEM) encapsulating deformable albumin-hitchhiking nanoemulsions (BIO, generated with bovine albumin, imiquimod adjuvant, and OVA antigen). Compared to conventional microparticles used for immune cell recruitment, BIO-GEM forms antigen-rich depots that better recruit antigen-presenting cells (APCs) and T cells, creating an immunostimulatory niche for in situ T-cell priming. Collagenase-responsive degradation of GEM triggers sustained release of BIO, which targets LNs via the albumin-hitchhiking pathway. This spatiotemporal delivery strategy synergizes bLN-resident immune activation with LN-directed antigen trafficking, yielding high CD8+ T-cell infiltration at injection sites, dendritic cell maturation, and elicitation of antigen-specific cytotoxic T cells. In multiple B16 murine melanoma models, BIO-GEM significantly suppressed tumor growth and extended the survival of mice. Intradermal vaccination was more efficacious than subcutaneous or intramuscular injection routes.\n\nID: 41746105\nTitle: Comparison of Immune Cell Transfection by Different Vaccine Vectors After Intradermal Injection.\nAbstract: Background/Objectives: Antigen presenting cells (APCs) and immune cells have unique properties to drive or suppress immune responses. They are therefore key targets for the expression of vaccine antigens or transgene proteins. To better determine the utility of different molecular therapies to modify these cells, mRNA and DNA-based molecular therapy vectors were compared for their ability to genetically modify immune cells after intradermal injections in mice. DNA-based vectors included naked plasmid DNA, plasmid packaged in lipid nanoparticles (LNPs), and replication-defective adenovirus (Ad) vectors. mRNA delivery was mediated by packaging into LNPs like those used in COVID-19 vaccines. Methods: Each vector was used to deliver Cre recombinase into Cre reporter mice whose cells were activated to express green fluorescent protein (GFP) and firefly luciferase after Cre recombination. The mice were injected intradermally (ID) near the base of their tail at a site that drains into the inguinal lymph node. Luciferase activity was imaged in the living mice 1 or 4 days after vector injection. The animals were then euthanized, and luciferase activity was imaged in the draining inguinal lymph node. Cells were prepared from the intradermal injection site and from the draining lymph node to determine which immune cells were genetically modified by phenotyping CD45, CD3, and CD11b GFP-positive cells by flow cytometry. Given that the skin uniquely contains Langerhans dendritic cells, these CD207+ cells were also phenotyped in skin samples and in the draining lymph node. Results: In both the skin and in the draining lymph node, the rank order of luciferase and GFP activation by the vectors were: (1) Ad; (2) mRNA-LNP; (3) DNA-LNP; and (4) naked DNA. Only mRNA-LNP and Ad vectors mediated obvious luciferase activity in the living animals and in the draining lymph nodes by imaging. Notably, both vectors appeared to leak from the ID injection site and not only modify the draining lymph node but also strongly modify the livers of the mice. Naked DNA and DNA-LNP mediated detectable GFP activation in the skin and draining lymph node in some mice, but this activity was low and did not reach statistical significance when compared to PBS-treated animals. mRNA-LNPs and Ad both mediated significant Cre delivery in CD45+, CD3+, CD11b+, and CD207+ immune cells in the skin and in the lymph node, with adenovirus mediating consistently higher levels of expression in all of the tested cells. Conclusions: These data indicate that mRNA-LNP and Ad vectors mediate stronger modification of skin and lymph node immune cells after intradermal injections. Naked DNA and DNA-LNPs were markedly less potent at this activity than the other vectors. These data are consistent with the higher vaccine potency of mRNA-LNP and Ad vectors and suggest that approaches that increase targeting of immune cell subsets may have utility to increase efficacy while also reducing off-target modification of tissues like the liver.\n\nID: 41418833\nTitle: Augmenting Subunit-Vaccine-Induced Immunity through a Dual Strategy of Gold Nanoparticle Conjugation and Chitosan Microneedle-Mediated Sustained Delivery.\nAbstract: Subunit vaccines offer high safety but often exhibit low immunogenicity and rapid clearance and require adjuvants. In this study, we developed a dual strategy for augmenting subunit-vaccine-induced immune responses by integrating self-adjuvanting gold nanoparticle (GNP)-antigen conjugates with implantable chitosan (CS) microneedles (MNs) to achieve sustained intradermal antigen exposure. Conjugation of a model antigen, namely, ovalbumin (OVA), onto the GNP surface (GNP-OVA) resulted in virus-mimicking multivalent antigen display, which substantially enhanced dendritic cell maturation, as evidenced by the upregulation of CD86 and major histocompatibility complex class II. This conjugation strategy also enabled the efficient codelivery of the antigen and carrier into the same antigen-presenting cells, thereby facilitating improved antigen presentation. Furthermore, compared with free OVA and a physical GNP/OVA mixture, conjugated GNP-OVA exhibited considerably longer lymph node retention, primarily because of its nanovaccine properties, which facilitate its preferential trafficking into lymphatic vessels and its subsequent accumulation in lymph nodes. Encapsulation of GNP-OVA into CS MNs (i.e., GNP-OVA MNs) resulted in reliable skin implantation, sustained intradermal antigen exposure, and local immune cell recruitment. Rat immunization studies revealed that GNP-OVA MNs induced balanced T helper 1 and T helper 2 responses and elicited considerably higher and more durable OVA-specific immunoglobulin G levels than did subcutaneous vaccination with GNP-OVA or OVA alone. These responses persisted for at least 16 weeks, highlighting the potential of the developed platform for prolonged subunit vaccine immunization. This dual-strategy platform, combining virus-mimicking GNP-based nanovaccines with immunostimulatory CS MNs, reduces reliance on external adjuvants and enhances the potency and durability of subunit vaccines. Its modular and patient-friendly design underscores its high potential for advancing the development of next-generation vaccines against emerging infectious diseases.\n\nID: 40698872\nTitle: Ultra-low dose superparamagnetic iron oxide nanoparticle injection for sentinel lymph node detection in breast cancer: prospective cohort study.\nAbstract: Sentinel lymph node (SLN) staging is essential in breast cancer. Superparamagnetic iron oxide nanoparticles (SPIO) is a tracer where the optimal injection technique is yet not defined. The aim was to evaluate SLN detection using 0.1\u2005ml SPIO intradermally compared to technetium-99\u2005m (Tc99) \u00b1 blue dye. Patients planned for breast surgery and SLN biopsy received 0.1\u2005ml SPIO intradermally at the areolar border or over the tumour. Tc99 \u00b1 blue dye was administered per clinical routine. Magnetic, radioactive, or blue nodes were removed and analysed separately. SLN detection and numbers, concordance, and skin discoloration were analysed. A total of 216 patients were included at five hospitals. Median age was 63 years, tumour size 15.9\u2005mm, and 91.7% underwent breast conservation. SPIO was injected a median of 12 days before surgery. SLN detection was 211/216 (97.7%; 95% c.i.: 94.7 to 99.2) and 215/216 (99.5%; 95% c.i.: 98.6 to 100.0) for SPIO and Tc99 \u00b1 blue dye (P = 0.111) respectively. In total, 403 SLNs were removed; 341 detected by SPIO and 349 by Tc99 \u00b1 blue dye. The median number of SLNs was 1 (iqr: 1-2) for both tracer methods. Among 46 SLN-positive patients, 42 were correctly staged with both tracers, two with SPIO only and two with Tc99 \u00b1 blue dye only. Skin discoloration was evaluated in 107 patients. The median discoloured area was 0\u2005cm2 (iqr: 0-0.7) among 49 patients with the injection site surgically removed and 1.3\u2005cm2 (iqr: 0.6-2.8) among 58 without removal. An ultra-low dose of 0.1\u2005ml intradermal injection of SPIO was non-inferior to Tc99 \u00b1 blue dye for SLN detection. Skin discoloration was limited and further reduced by removal during surgery. A new magnetic liquid with small particles of iron has been introduced to find the first lymph node in line of the drainage from a breast cancer. The liquid is injected in the breast and the node can be detected with a magnetometer, most often in the armpit. In this study an ultra-low dose of the magnetic liquid was compared to today\u2019s standard, a radioactive liquid. Each patient was injected with both liquids before surgery. It was shown that the very low dose of magnetic liquid was equally good as the standard of today for sentinel lymph node detection. The magnetic liquid is better in some ways, as no radioactivity is needed and it can be injected several weeks before surgery.\n\nID: 40362678\nTitle: Intradermal Injection of a Protein Alone Without Additional Adjuvants Using a Needle-Free Pyro-Drive Jet Injector Induces Potent CD8+ T Cell-Mediated Antitumor Immunity.\nAbstract: Vaccines usually contain an adjuvant that activates innate immunity to promote the acquisition of adaptive immunity. Aluminum and lipid nanoparticles have been used for this purpose, but their accumulation or widespread circulation in the body can lead to adverse effects. In contrast, physical adjuvants, which use physical energy to transiently stress tissues, do not persist in exposed tissues or cause lasting adverse effects. Herein, we investigate the effects of intradermal injection of endotoxin-free ovalbumin (OVA) protein alone without additional adjuvants using a needle-free pyro-drive jet injector (PJI) on tumor vaccination efficacy. Intradermal injection of OVA protein alone using PJI significantly increased OVA-specific CD8+ T cell expansion in the lymph node, although lymph node swelling was much less than when aluminum hydroxide was used. The injection also induced OVA-specific killing activity and antibody production and showed strong CD8+ T cell-dependent prophylactic antitumor effects against transplanted E.G7-OVA tumors. In particular, intradermal injection of the fluorescent OVA protein significantly enhanced its uptake by XCR1+ dendritic cells, which have a strong ability to cross-present extracellular proteins in the skin and draining lymph nodes. In addition, the injection increased the expression of HMGB1, one of the potent danger signals whose expression has been reported to increase in response to shear stress. Thus, intradermal injection of OVA protein alone without any additional adjuvants using PJI induces potent CD8+ T cell-mediated antitumor immunity by enhancing its uptake into XCR1+ dendritic cells, which have a high cross-presentation capacity accompanied by an increased expression of shear stress-induced HMGB1.\n\nID: 40202614\nTitle: Extracellular Vesicles from Dendritic Cells Protect Against Sporothrix brasiliensis Yeast Cells.\nAbstract: Sporotrichosis is an emerging subcutaneous mycotic zoonosis that affects the skin, lymphatic system, and other organs of humans and animals. Like other infectious fungal diseases, it becomes even more severe when it affects immunosuppressed patients. This infection has a global distribution and is endemic in some regions of Brazil and it is an important zoonotic public health problem. The disease is caused by a complex of at least four pathogenic species, including Sporothrix brasiliensis. The immunological response against these species has not yet been completely elucidated. Still, structures such as extracellular vesicles could carry important components that can contribute to the modulation and control of this significant infection. Thus, this work aims to analyze the participation of EVs from na\u00efve dendritic cells and EVs from DCs previously primed with S. brasiliensis yeast and primed with EVs from the fungus in the immune response against experimental sporotrichosis in murine models. The groups that received EVs from DCs primed with S. brasiliensis or their EVs showed a significant decrease in fungal load compared to the negative control group. When we analyzed the cytokine profile in the skin of mice treated with EVs before infection, we observed an increase in IFN-\u213d, TNF-\u03b1, IL-17, and IL-10, mainly in animals previously treated with EVs from DCs cultivated with yeast cells. It is worth highlighting that all prophylactic protocols modulated and minimized fungal growth compared to the control; that is, EVs contributed to the control of the infection and acted in favor of the host, demonstrating a protective character.\n\nID: 37517544\nTitle: Logistics and distribution of small extracellular vesicles from the subcutaneous space to the lymphatic system.\nAbstract: Small extracellular vesicles (sEVs) are small, cell-derived particles with sizes of approximately 100\u00a0nm. Since these particles include cargos such as host cell-derived proteins, messenger RNAs, and micro RNAs, they serve as mediators of cell-cell communication. While the analysis of the pharmacokinetic of sEVs after the intravenous injection have been reported, the lymphatic transport of sEVs remains unclear. The objective of this study was to provide insights into the intra-lymphatic trafficking and distribution of sEVs when they are injected into an interstitial space both in normal skin tissue and in cancerous tissue. When sEVs were Subcutaneously administered into the tail base and the tumor tissue, they preferably accumulated in the lymph nodes (LNs), rather than in the liver and the spleen. The findings reported herein show that the lymphatic transport of sEVs was drastically changed in model mice, in which a surgical treatment was used to modify to allow the dominant lymphatic flow from the footpad directly to the axillary LN via the inguinal LN. Based on the results, we conclude that when sEVs are injected into the subcutis space, they are preferably delivered to the LN via the lymphatic system. Further, the extent of accumulation of sEVs in the LN after subcutaneous injection was reduced when they were preliminarily incubated with Proteinase K. These results suggest that the lymphatic drainage of sEVs in normal skin tissue is regulated by membrane proteins on their surface. This reduction, however, was not observed in the case of cancer tissue. This discrepancy can be attributed to the presence of highly permeable lymphatic vessels in the tumor tissue. Further, the major cell subtypes that captured sEVs in the LN were LN-resident medullary sinus macrophages. These collective findings indicate that the lymphatic drainage of sEVs are mediated by proteins and, that they may appear to contribute to the control of the function of immune-responsive cells in the LNs.\n\nID: 37314544\nTitle: Ultra-Low Dose of Superparamagnetic Iron Oxide Nanoparticles for Sentinel Lymph Node Detection in Patients with Breast Cancer.\nAbstract: Sentinel lymph node (SLN) status is pivotal for treatment decision-making in patients with breast cancer. Superparamagnetic iron oxide nanoparticles (SPIO) have been shown to be equivalent to the dual technique with technetium99m (Tc99) and blue dye (BD) for SLN detection. The aim of this study was to determine the feasibility of detecting SLNs using an ultra-low dose of SPIO. Patients planned for breast conserving surgery and SLN biopsy were included. An intradermal injection of 0.1 mL SPIO was administered at the areolar border up to 7 days before surgery. Tc99/BD was administered according to clinical routine. SLNs were detected during surgery using a handheld magnetometer. All nodes with a magnetic and/or radioactive signal, as well as blue or clinically suspicious nodes, were harvested and analyzed. In 50 patients, SPIO was injected a median of 4 days before surgery. At least one SLN was found in all patients with both methods. A total of 98 SLNs were removed; 90 were detected using SPIO and 88 using Tc99/BD. Of the 90 SLNs detected by SPIO, 80 were Tc99/BD positive (concordance 89%). Histopathological analysis classified 16 patients with tumor cells deposit and 9 with macro-metastasis > 2mm, where one SLN was identified only by the radioactive technique and one only by the magnetic technique. SLN detection using 0.1 mL ultra-low dose SPIO injected intradermally was successful in all patients. A future analysis will determine whether the approach using an ultra-low dose of SPIO injected intradermally will minimize skin staining and MRI artefacts.\n\nID: 36822367\nTitle: X-ray irradiation negatively affects immune responses in the lymphatic network.\nAbstract: Immune checkpoint inhibitor therapy has been attracting attention as a new cancer treatment and is likely to be widely used in combination with radiotherapy. Therefore, examination of the effects of X-ray irradiation on sentinel lymph nodes and lymphatic vessels, which are involved in antigen presentation, is important for therapy. The hindlimbs of mice were irradiated with X-rays (total radiation doses: 2, 10, and 30\u00a0Gy), and X-ray computed tomography (CT) imaging was performed using 15-nm or 2-nm gold nanoparticles (AuNPs) as contrast agents on days 7, 14, and 28 after irradiation to evaluate the diameter of the collecting lymph vessels and lymph flow within the irradiated area. X-ray CT imaging data using 15-nm AuNPs on day 28 after irradiation showed that the diameter of the collecting lymph vessels was significantly larger in all irradiated groups compared to the control group (p\u00a0\u2264\u00a00.01). CT imaging with 2-nm AuNPs showed that lymphatic drainage was significantly reduced in the lymph nodes irradiated with 10\u00a0Gy and 30\u00a0Gy compared to the lymph nodes irradiated with 2\u00a0Gy (p\u00a0\u2264\u00a00.05). Additionally, immunohistochemical analyses were conducted to evaluate the area density and morphology of high endothelial venules (HEVs) in the lymph nodes, which are important vessels for naive T cells to enter the lymph nodes. The expression level of MECA-79, which specifically localized to HEVs, was significantly decreased in the 10\u00a0Gy and 30\u00a0Gy irradiation groups compared to the control group (p\u00a0\u2264\u00a00.05). There was a significant decrease in normal HEV morphology (p\u00a0\u2264\u00a00.05) and a significant increase in abnormal HEV morphology (p\u00a0\u2264\u00a00.05) in all irradiated groups. These results also showed that X-ray irradiation induced a time- and radiation dose-dependent increase in the diameter of the collecting lymph vessels, stagnation of intralymphatic lymph flow, and a reduction in the area density of HEVs and their abnormal morphology, demonstrating that X-ray irradiation affected the immune responses. Therefore, these findings suggest that X-ray irradiation to lymph nodes may impair the opportunity for antigen presentation in the lymph nodes, which is the key to cancer immunity, and that for this reason, it is important to carefully plan irradiation of sentinel lymph nodes and develop treatment strategies according to future treatment options.\n\nID: 36497498\nTitle: A Comparison of Skin Staining after Sentinel Lymph Node Biopsy in Women Undergoing Breast Cancer Surgery Using Blue Dye and Superparamagnetic Iron Oxide Nanoparticle (SPIO) Tracers.\nAbstract: Superparamagnetic iron oxide nanoparticles (SPIO) are a tracer for sentinel lymph node (SLN) detection. In a preplanned secondary analysis of a prospective clinical trial (SentiDose) we reported on skin staining after SPIO and blue dye (BD) injections. For SPIO, either a 1.5 mL retroareolar injection on the day of surgery or a 1.0 mL peritumoral/retroareolar injection 1-7 days before surgery was given. A 1.0 mL sub-/intradermal periareolar injection of BD was also administered to all these women. Staining was then assessed at 6, 12 and 24 months after surgery. A total of 270 women received SPIO and were operated on with breast-conserving surgery. Of these, 204 women also received BD. A total of 58 (21.5%) women had an SPIO stain 6 months postoperatively with a median size of 6.8 cm2 (p = 0.56), while 51 (25.0%) had a BD stain with a median size of 8.5 cm2 (p = 0.93). The incidence and size of SPIO and BD staining decreased over time reciprocally. At 24 months, the incidence and median size of SPIO was 23 (8.6%) and 4 cm2, respectively. For BD, the incidence was 14 (6.3%, p = 0.13), and the median size was 3.5 cm2 (p = 0.18). There was, therefore, no statistically significant difference in the incidence or size of skin staining between SPIO and BD over time.\n\nID: 35835068\nTitle: Ovalbumin and Poly(i:c) Encapsulated Dendritic Cell-Targeted Nanoparticles for Immune Activation in the Small Intestinal Lymphatic System.\nAbstract: Here, antigen and adjuvant encapsulated dendritic cell-targeted nanoparticles for immune activation in the small intestinal lymphatic system to inhibit melanoma development are described. This strategy is demonstrated using chondroitin sulfate-coated nanoparticles (OPGMN) grafted with glycocholic acid and mannose for cationic liposomes encapsulated with ovalbumin as an antigen and polyinosine-polycytidylic acid as a cancer-specific adjuvant. OPGMN is absorbed in the gastrointestinal tract and delivered to the lymph nodes when orally administered. Oral delivery of OPGMN induces increased dendritic cell maturation compared to the intradermal route in the lymph node and induces T helper type 1 and type 2 responses, such as immunoglobulin G1 and G2c, interferon-gamma, and interleukin-2, in the blood. Repeated oral administration of OPGMN increases the population of CD3+ CD8+ T cells, CD44high CD62Llow memory T cells, and CD11b+ CD27+ natural killer cells in the blood. OPGMN completely prevents melanoma development in the B16F10-bearing C57BL/6 mouse model by reducing the population of CD4+ CD25+ Foxp3+ regulatory T cells in the blood. This strategy is expected to prevent the recurrence of tumors after various cancer treatments.\n\nID: 35381399\nTitle: Nanoparticles with dense poly(ethylene glycol) coatings with near neutral charge are maximally transported across lymphatics and to the lymph nodes.\nAbstract: Lymphatic vessels have recently been shown to effectively deliver immune modulatory therapies to the lymph nodes, which enhances their therapeutic efficacy. Prior work has shown that lymphatics transport 10-250 nm nanoparticles from peripheral tissues to the lymph node. However, the surface chemistry required to maximize this transport is poorly understood. Here, we determined the effect of surface poly(ethylene glycol) (PEG) density and size on nanoparticle transport across lymphatic endothelial cells (LECs) by differentially PEGylated model polystyrene nanoparticles. Using an established in-vitro lymphatic transport model, we found PEGylation improved the transport of 100 and 40 nm nanoparticles across LECs 50-fold compared to the unmodified nanoparticles and that transport is maximized when the PEG is in a dense brush conformation or high grafting density (Rf/D\u00a0=\u00a04.9). We also determined that these trends are not size-dependent. PEGylating 40 nm nanoparticles improved transport efficiency across LECs 68-fold compared to unmodified nanoparticles. We also found that PEGylated 100 nm and 40 nm nanoparticles accumulate in lymph nodes within 4 h after intradermal injection, while unmodified nanoparticles accumulated minimally. Densely PEGylated nanoparticles traveled the furthest distance from the injection site and densely PEGylated 40 nm nanoparticles had maximum accumulation in the lymph nodes compared to low density PEGylated and unmodified nanoparticles. Finally, we determined that nanoparticles are transported via both paracellular and transcellular mechanisms, and that PEG conformation modulates the cellular transport mechanisms. Our results suggest that PEG conformation is crucial to maximize nanoparticle transport across LECs and into lymphatic vessels, making PEG density a crucial design. Optimizing PEG density on nanoparticle formulations has the potential to enhance immunotherapeutic and vaccine outcomes. STATEMENT OF SIGNIFICANCE: Lymphatic vessels are an emerging target for drug delivery both in the context of modulating immune responses and enhancing bioavailability by avoiding first pass hepatic metabolism after oral delivery. Lymphatic vessels are the natural conduits from peripheral tissues to the lymph nodes, where the adaptive immune response is shaped, and eventually to systemic circulation via the thoracic duct. Lymphatics can be targeted via nanoparticles, but the surface chemistry required to maximize nanoparticle transport by lymphatics vessels remains poorly understood. Here, we demonstrate that coating nanoparticles with hydrophilic polyethylene glycol (PEG) effectively enhances their transport across lymphatic endothelial cells in vitro and in vivo and that both paracellular and micropinocytosis mechanisms underly this transport. We found that dense PEG coatings maximize lymphatic transport of nanoparticles, thus providing new material design criteria for lymphatic targeted drug delivery.\n\nID: 33712074\nTitle: The value of contrast-enhanced ultrasound in determining the location of sentinel lymph nodes in breast cancer.\nAbstract: This study aimed to explore the sentinel lymph node (SLN) identification rate in breast cancer by subcutaneous and intradermal injection of ultrasound contrast agent in the mammary areola region, compared to the results achieved with methylene blue (MB). A total of 390 breast cancer patients with planned sentinel lymph node biopsy from our breast surgery department from July 2017 to February 2019 were enrolled. All patients were subjected to preoperative contrast-enhanced ultrasound (CEUS), that involved an intracutaneous injection of 1 mL ultrasonic contrast agent (UCA) at 3 and 6 o 'clock, as well as a subcutaneous injection of 1 mL UCA at 9 and 12 o'clock. The enhanced lymph nodes along the enhanced lymphatic vessels from the mammary areola were traced. The number of enhanced lymph nodes were recorded, and an ultrasound-guided injection of 1:10 diluted carbon nanoparticles were used to mark all first site enhanced lymph nodes (i.e., SLNs). An intraoperative dye method (MB) was used to track the SLNs and the results were compared with the CEUS findings. Among the 390 cases of breast cancer, enhanced SLNs were observed in 373 patients after an injection of UCA with an identification rate of 95.64\u2009% (373/390), compared to the identification rate of 92.05\u2009% (359/390) using the intraoperative MB. The difference between the two methods was statistically significant (P\u2009=\u20090.016). And among the 390 patients, a total of 808 enhanced lymph nodes were traced by preoperative CEUS, with a median of 2 (1,3). A total of 971 blue-stained lymph nodes were traced using the intraoperative MB, with a median of 2 (2,3), indicating a statistically significant difference (p\u2009<\u20090.001). Intradermal and subcutaneous injections of UCA in the mammary areola region may have clinical application value for the identification and localization of SLNs in breast cancer patients. The identification rate is higher than that of blue dye method, which can be used as a new tracer of sentinel lymph node biopsy and complement other staining methods to improve the success rate.\n\nID: 33380496\nTitle: Effective and Safe Stimulation of Humoral and Cell-Mediated Immunity by Intradermal Immunization with a Cyclic Dinucleotide/Nanoparticle Combination Adjuvant.\nAbstract: Intradermal (ID) immunization is an attractive route of vaccination because it targets tissue rich in dendritic cells, has dose-sparing potential, and allows needle-free delivery. However, few adjuvants are effective, nonreactogenic, and compatible with needle-free delivery devices. In this study, we demonstrate that a combination adjuvant composed of cyclic-di-AMP (cdAMP) and the plant-derived nanoparticle adjuvant Nano-11 significantly enhanced the immune response to ID-injected vaccines in mice and pigs with minimal local reaction at the injection site. The cdAMP/Nano-11 combination adjuvant increased Ag uptake by lymph node-resident and migratory skin dendritic cell subpopulations, including Langerhans cells. ID immunization with cdAMP/Nano-11 expanded the population of germinal center B cells and follicular helper T cells in the draining lymph node and Ag-specific Th1 and Th17 cells in the spleen. It elicited an enhanced immune response with a significant increase of IgG1 and IgG2a responses in mice at a reduced dose compared with i.m. immunization. An increased IgG response was observed following needle-free ID immunization of pigs. Nano-11 and cdAMP demonstrated a strong synergistic interaction, as shown in the activation of mouse, human, and porcine APC, with increased expression of costimulatory molecules and secretion of TNF and IL-1\u03b2. The combination adjuvant induced robust activation of both NF-\u03baB and IFN regulatory factor signaling pathways and the NLRP3 inflammasome. We conclude that the combination of Nano-11 and cdAMP is a promising adjuvant for ID delivery of vaccines that supports a balanced immune response.\n\nID: 33080460\nTitle: Lymph-directed nitric oxide increases immune cell access to lymph-borne nanoscale solutes.\nAbstract: Lymph nodes (LNs) are immune organs housing high concentrations of lymphocytes, making them critical targets for therapeutic immunomodulation in a wide variety of diseases. While there is great interest in targeted drug delivery to LNs, many nanoscale drug delivery carriers have limited access to parenchymal resident immune cells compared to small molecules, limiting their efficacy. Nitric oxide (NO) is a potent regulator of vascular and lymphatic transport and a promising candidate for modulating nanocarrier access to LNs, but its lymphatic accumulation is limited by its low molecular weight and high reactivity. In this work, we employ S-nitrosated nanoparticles (SNO-NP), a lymphatic-targeted delivery system for controlled NO release, to investigate the effect of NO application on molecule accumulation and distribution within the LN. We evaluated the LN accumulation, spatial distribution, and cellular distribution of a panel of fluorescent tracers after intradermal administration alongside SNO-NP or a small molecule NO donor. While SNO-NP did not alter total tracer accumulation in draining lymph nodes (dLNs) or affect active cellular transport of large molecules from the injection site, its application enhanced the penetration of nanoscale 30\u00a0nm dextrans into the LN and their subsequent uptake by LN-resident lymphocytes, while nontargeted NO delivery did not. These results further extended to a peptide-conjugated NP drug delivery system, which showed enhanced uptake by B cells and dendritic cells when administered alongside SNO-NP. Together, these results highlight the utility of LN-targeted NO application for the enhancement of nanocarrier access to therapeutically relevant LN-resident immune cells, making NO a potentially useful tool for improving LN drug delivery and immune responses.\n\nID: 32032584\nTitle: Gliadin Nanoparticles Induce Immune Tolerance to Gliadin in Mouse Models of Celiac Disease.\nAbstract: Celiac disease could be treated, and potentially cured, by restoring T-cell tolerance to gliadin. We investigated the safety and efficacy of negatively charged 500-nm poly(lactide-co-glycolide) nanoparticles encapsulating gliadin protein (TIMP-GLIA) in 3 mouse models of celiac disease. Uptake of these nanoparticles by antigen-presenting cells was shown to induce immune tolerance in other animal models of autoimmune disease. We performed studies with C57BL/6; RAG1-/- (C57BL/6); and HLA-DQ8, huCD4 transgenic Ab0 NOD mice. Mice were given 1 or 2 tail-vein injections of TIMP-GLIA or control nanoparticles. Some mice were given intradermal injections of gliadin in complete Freund's adjuvant (immunization) or of soluble gliadin or ovalbumin (ear challenge). RAG-/- mice were given intraperitoneal injections of CD4+CD62L-CD44hi T cells from gliadin-immunized C57BL/6 mice and were fed with an AIN-76A-based diet containing wheat gluten (oral challenge) or without gluten. Spleen or lymph node cells were analyzed in proliferation and cytokine secretion assays or by flow cytometry, RNA sequencing, or real-time quantitative polymerase chain reaction. Serum samples were analyzed by gliadin antibody enzyme-linked immunosorbent assay, and intestinal tissues were analyzed by histology. Human peripheral blood mononuclear cells, or immature dendritic cells derived from human peripheral blood mononuclear cells, were cultured in medium containing TIMP-GLIA, anti-CD3 antibody, or lipopolysaccharide (controls) and analyzed in proliferation and cytokine secretion assays or by flow cytometry. Whole blood or plasma from healthy volunteers was incubated with TIMP-GLIA, and hemolysis, platelet activation and aggregation, and complement activation or coagulation were analyzed. TIMP-GLIA did not increase markers of maturation on cultured human dendritic cells or induce activation of T cells from patients with active or treated celiac disease. In the delayed-type hypersensitivity (model 1), the HLA-DQ8 transgenic (model 2), and the gliadin memory T-cell enteropathy (model 3) models of celiac disease, intravenous injections of TIMP-GLIA significantly decreased gliadin-specific T-cell proliferation (in models 1 and 2), inflammatory cytokine secretion (in models 1, 2, and 3), circulating gliadin-specific IgG/IgG2c (in models 1 and 2), ear swelling (in model 1), gluten-dependent enteropathy (in model 3), and body weight loss (in model 3). In model 1, the effects were shown to be dose dependent. Splenocytes from HLA-DQ8 transgenic mice given TIMP-GLIA nanoparticles, but not control nanoparticles, had increased levels of FOXP3 and gene expression signatures associated with tolerance induction. In mice with gliadin sensitivity, injection of TIMP-GLIA nanoparticles induced unresponsiveness to gliadin and reduced markers of inflammation and enteropathy. This strategy might be developed for the treatment of celiac disease.\n\nID: 31917298\nTitle: Carboxyl-, sulfonyl-, and phosphate-terminal dendrimers as a nanoplatform with lymph node targeting.\nAbstract: The development of drug delivery vehicles to cancer and/or immune cells in lymph nodes is important for cancer diagnosis, therapy, and immunotherapy. We previously reported that anionic carboxyl-terminal dendrimers were accumulated in lymph nodes. In this study, three anionic dendrimers with carboxyl-, sulfonyl-, and phosphate-terminal groups were prepared to examine the lymph node targeting and the association with immune cells in the lymph nodes. These anionic dendrimers were accumulated in the lymph node by intradermal injection. Although the carboxyl- and sulfonyl-terminal dendrimers were diffused from the injection site, the phosphate-terminal dendrimers were mostly retained. The phosphate-terminal dendrimer was recognized by the macrophages, dendritic cells, and B cells in the lymph node, whereas the carboxyl- and sulfonyl-terminal dendrimers were not. Our results show that these anionic dendrimers were accumulated in the lymph node where the association with immune cells could be controlled by the terminal structure of the dendrimer. The phosphate-terminal dendrimer can be used as a nanoplatform for the delivery of some bioactive molecules to some immune cells, including B cells, in the lymph node.\n\nID: 31871957\nTitle: Nanoparticles versus Dendritic Cells as Vehicles to Deliver mRNA Encoding Multiple Epitopes for Immunotherapy.\nAbstract: The efficacy of antigen-specific immunotherapy relies heavily on efficient antigen delivery to antigen-presenting cells and engagement of as many disease-relevant T\u00a0cells as possible in various lymphoid tissues, which are challenging to achieve. Here, we compared two approaches to deliver mRNA encoding multiple epitopes targeting both CD4+ and CD8+ T\u00a0cells: a lipid-based nanoparticle platform to target endogenous antigen-presenting cells in\u00a0vivo versus ex\u00a0vivo mRNA-electroporated dendritic cells. After intraperitoneal injection, the nanoparticle platform facilitated efficient entry of mRNA into various endogenous antigen-presenting cells, including lymph node stromal cells, and elicited robust T\u00a0cell responses within a wider network of lymphoid tissues compared with dendritic cells. Following intravenous injection, mRNA-electroporated dendritic cells and the nanoparticle platform localized primarily in lung and spleen, respectively. When administered locally via an intradermal route, both platforms resulted in mRNA expression at the injection site and in robust T\u00a0cell responses in draining lymph nodes. This study indicates that multiple epitopes, customizable for specific patient populations and encoded by mRNA, can be targeted to different lymphoid tissues based on delivery vehicle and route, and constitute the groundwork for future studies using mRNA to reprogram exogenous or endogenous APCs for immunotherapy.\n\nID: 30889749\nTitle: Surface charge of well-defined polymeric nano-stars regulates non-invasive fluorescence imaging of lymph node.\nAbstract: Accurate identification of sentinel lymph node (SLN) is crucial for clinical SLN biopsy surgery. Herein, we developed an innovative nanoprobe based on well-defined core crosslinked star (CCS) polymers for non-invasive fluorescence imaging of SLN. A well-defined biodegradable CCS polymer comprising multiple polyethylene glycol (PEG) arms and carboxyl terminal groups (denoted as CCS-COOH) was synthesized successfully by reversible addition-fragmentation chain transfer polymerization with a disulfide-based crosslinker reagent. Besides, CCS-COOH was coupled by tert-butyl carbazate to produce the CCS derivative with neutral butoxycarbonyl (Boc) terminal groups (denoted as CCS-Boc). By the removal of Boc groups, another CCS derivative with positive primary amino terminal groups (denoted as CCS-NH2) was also yielded. These CCS polymers had similar particle size but different surface charge. For SLN fluorescence imaging, the CCS polymers labeled by CY7, a near-infrared probe, exhibited superior in vitro photo-stability to CY7 alone. After intradermal injection of the CY7-labeled CCS polymers in a mouse model, they could efficiently accumulate in the lymph node of the mouse. CY7-labeled CCS-COOH having negatively-charged surface displayed longer duration time and higher fluorescence intensity in the lymph node as compared to its counterparts with neutral or positive charge surface. In vitro and in vivo toxicity tests supported low cytotoxicity of these CCS polymers against cell lines and low systemic toxicity. The results of this work highlight the potential of negatively-charged near-infrared-emitting CCS polymer as a new nanoprobe for safe and efficient SLN imaging.\n\nID: 30333803\nTitle: Extracellular Vesicles From Sporothrix brasiliensis Are an Important Virulence Factor That Induce an Increase in Fungal Burden in Experimental Sporotrichosis.\nAbstract: Sporotrichosis is a mycosis that affects the skin, lymphatic system and other organs in humans and animals. The disease has a worldwide distribution, with endemic areas in Brazil, and is caused by a complex of species, including Sporothrix brasiliensis. Some fungi release extracellular vesicles (EVs) that can interact with the host cell and modulate the host immune response. The aim of this study was to analyze the participation of S. brasiliensis EVs in the modulation of dendritic cells (DCs) and in the control of infection in vivo. Our results showed that in vitro, the EVs isolated from S. brasiliensis induced an increase in the phagocytic index and fungal burden in DCs. In addition, we observed a significant increase in IL-12p40 and TNF-\u03b1 cytokine production. Then, the EVs were inoculated into BALB/c mice before subcutaneous infection with yeast, and the lesion was analyzed after 21, 35, and 42 days. An increase in fungal burden and lesion diameter were observed after 21 days in mice inoculated with a high concentration of EVs. However, after 35 days, we observed a regression of the lesion, which persisted until 42 days after infection. Interestingly, we observed an increase in fungal burden in these mice. In addition, we observed the presence of immunogenic components and proteins that could be related with virulence in EVs. These results suggest that EVs can play an important role in virulence and modulation of the host immune system during experimental S. brasiliensis infection.\n\nID: 30036073\nTitle: Simultaneous Preclinical Positron Emission Tomography-Magnetic Resonance Imaging Study of Lymphatic Drainage of Chelator-Free 64Cu-Labeled Nanoparticles.\nAbstract: Hybrid positron emission tomography (PET)-magnetic resonance imaging (MRI) systems have been taken in use as new clinical diagnostic tools including detection and therapy planning of cancer. To reduce the amount of contrast agents injected in patients while fully benefitting both modalities, dual-modality probes are required. This study was first aimed at developing a hybrid PET-MRI probe by labeling superparamagnetic iron oxide nanoparticles (SPIONs) with 64Cu using a fast and chelator-free conjugation method, and second, to demonstrate the ability of the agent to target sentinel lymph nodes (SLNs) in vivo using simultaneous PET-MRI imaging. High labeling efficiency of 97% produced within 10-15\u2009min was demonstrated at room temperature. 64Cu-SPIONs were chemically stable in mouse serum for 24\u2009h and after intradermal injection in the hind paw of C57BL/6J mice, demonstrated specific accumulation in the SLN. Simultaneous PET-MRI clearly demonstrated visualization of 64Cu-SPIONs, in dynamic and static imaging sequences up to 24\u2009h after administration. The use of a single hybrid probe and simultaneous hybrid imaging provides an efficient, complementary integration of quantitation and is expected to improve preoperative planning and intraoperative guidance of cancer treatments.\n\nID: 29352735\nTitle: Winner of the society for biomaterials young investigator award for the annual meeting of the society for biomaterials, April 11-14, 2018, Atlanta, GA: S-nitrosated poly(propylene sulfide) nanoparticles for enhanced nitric oxide delivery to lymphatic tissues.\nAbstract: Nitric oxide (NO) is a therapeutic implicated for the treatment of diseases afflicting lymphatic tissues, which range from infectious and cardiovascular diseases to cancer. Existing technologies available for NO therapy, however, provide poor bioactivity within lymphatic tissues. In this work, we address this technology gap with a NO encapsulation and delivery strategy leveraging the formation of S-nitrosothiols on lymphatic-targeting pluronic-stabilized, poly(propylene sulfide)-core nanoparticles (SNO-NP). We evaluated in vivo the lymphatic versus systemic delivery of NO resulting from intradermal administration of SNO-NP benchmarked against a commonly used, commercially available small molecule S-nitrosothiol NO donor, examined signs of toxicity systemically as well as localized to the site of injection, and investigated SNO effects on lymphatic transport and NP uptake by lymph node (LN)-resident cells. Donation of NO from SNO-NP, which scaled in proportion to the total administered dose, enhanced LN accumulation by two orders of magnitude without substantially reducing lymphatic transport of NP or the viability and extent of NP uptake by LN-resident cells. Additionally, NO delivery by SNO-NP was accompanied by low-to-negligible NO accumulation in systemic tissues with no apparent inflammation. These results suggest the utility and selectivity of SNO-NP for the targeted treatment of NO-regulated diseases that afflict lymphatic tissues. \u00a9 2018 Wiley Periodicals, Inc.

Traditional vaccine platforms, such as live-attenuated or inactivated pathogens, although immunogenic, often present safety concerns. Conversely, subunit vaccines, despite being safer, generally exhibit poor immunogenicity due to inadequate delivery of antigens to professional antigen-presenting cells (APCs). To address this issue, the development of innovative delivery systems has become a pivotal strategy to overcome significant biological barriers, including extracellular antigen degradation, suboptimal lymph node targeting, and inefficient cross-presentation necessary for CD8+ T cell activation. This review systematically explores recent advancements in delivery technologies aimed at enhancing antigen presentation, encompassing rationally engineered nanocarriers and sophisticated biomimetic platforms. We first examine how nanoparticle properties like size, surface charge, and ligand density affect intracellular trafficking and the transition from MHC-II to MHC-I cross-presentation. Then, we explore bioinspired systems such as extracellular vesicles, virus-like particles, and cell-membrane-coated nanoparticles that utilize natural biological traits for enhanced targeting and immune modulation. Additionally, we review new physical delivery methods like microneedle arrays and in situ electroporation for direct, minimally invasive antigen delivery to dendritic cells. Lastly, we discuss the potential of these platforms in personalized cancer vaccines and combination immunotherapies. By combining insights from materials science, immunology, and bioengineering, these next-generation delivery tools could enhance antigen presentation and transform precision vaccination and immune intervention.\n\nID: 40016753\nTitle: A self-adjuvant multiantigenic nanovaccines simultaneously activate the antiviral and antitumor immunity for the treatment of cancers.\nAbstract: Tumor cell-derived extracellular vesicles (tEVs) have garnered significant attention as promising antigen delivery vehicles for the development of cancer vaccines. However, their practical applications are hindered by weak immunogenicity and inadequate lymph node targeting. In this study, we engineered tEVs into \"self-adjuvant\" multiantigenic nanovaccines that simultaneously accumulate in tumors and lymph nodes (LNs), effectively triggering innate and adaptive immunity capable of recognizing both tumor cells and virus antigen-modified tumor cells to inhibit tumor progression. 4T1 tumor cells were infected with vesicular stomatitis virus (VSV), leading to the expression of VSVG and calreticulin (CRT) on their surface. Using these infected cells, we prepared extracellular vesicles (vEVs) carrying both VSVG and CRT. When injected subcutaneously, vEVs targeted tumors effectively due to the homologous targeting capability of tumor cell membranes. In which, VSVG induced fusion between vEVs and tumor cells, creating viral antigen-decorated tumor cells, which enhanced the recognition and phagocytosis of tumor cells by macrophages. Additionally, the surface CRT of vEVs activated the \"eat-me\" signaling, thus improving their recognition and uptake by dendritic cells (DCs). This led to DC maturation and the activation of antiviral and antitumor T cells, synergistically inhibiting tumor growth. This research introduces a straightforward yet efficacious methodology for the production of cancer vaccines to fight cancer through the stimulation of both the antiviral and antitumor immune responses within the body.\n\nID: 39315589\nTitle: Enhancing protective immunity against bacterial infection via coating nano-Rehmannia glutinosa polysaccharide with outer membrane vesicles.\nAbstract: With the coming of the post-antibiotic era, there is an increasingly urgent need for safe and efficient antibacterial vaccines. Bacterial outer membrane vesicles (OMVs) have received increased attention recently as a potential subunit vaccine. OMVs are non-replicative and contain the principle immunogenic bacterial antigen, which circumvents the safety concerns of live-attenuated vaccines. Here, we developed a novel nano-vaccine by coating OMVs onto PEGylated nano-Rehmannia glutinosa polysaccharide (pRL) in a structure consisting of concentric circles, resulting in a more stable vaccine with improved immunogenicity. The immunological function of the pRL-OMV formulation was evaluated in vivo and in vitro, and the underlying mechanism was studied though transcriptomic analysis. The pRL-OMV formulation significantly increased dendritic cell (DC) proliferation and cytokine secretion. Efficient phagocytosis of the formulation by DCs was accompanied by DC maturation. Further, the formulation demonstrated superior lymph node targeting, contributing to a potent mixed cellular response and bacterial-specific antibody response against Bordetella bronchiseptica infection. Specifically, transcriptomic analysis revealed that the immune protection function correlated with T-cell receptor signalling and Th1/Th2/Th17 differentiation, among other markers of enhanced immunological activity. These findings have implications for the future application of OMV-coated nano-carriers in antimicrobial immunotherapy.\n\nID: 35879268\nTitle: Extracellular vesicles engineered to bind albumin demonstrate extended circulation time and lymph node accumulation in mouse models.\nAbstract: Extracellular vesicles (EVs) have shown promise as potential therapeutics for the treatment of various diseases. However, their rapid clearance after administration could be a limitation in certain therapeutic settings. To solve this, an engineering strategy is employed to decorate albumin onto the surface of the EVs through surface display of albumin binding domains (ABDs). ABDs were either included in the extracellular loops of select EV-enriched tetraspanins (CD63, CD9 and CD81) or directly fused to the extracellular terminal of single transmembrane EV-sorting domains, such as Lamp2B. These engineered EVs exert robust binding capacity to human serum albumins (HSA) in vitro and mouse serum albumins (MSA) after injection in mice. By binding to MSA, circulating time of EVs dramatically increases after different routes of injection in different strains of mice. Moreover, these engineered EVs show considerable lymph node (LN) and solid tumour accumulation, which can be utilized when using EVs for immunomodulation, cancer- and/or immunotherapy. The increased circulation time of EVs may also be important when combined with tissue-specific targeting ligands and could provide significant benefit for their therapeutic use in a variety of disease indications.\n\nID: 31141293\nTitle: Mannose-Modified Serum Exosomes for the Elevated Uptake to Murine Dendritic Cells and Lymphatic Accumulation.\nAbstract: The surface of bovine serum-derived exosomes (EXOs) are modified with \u03b1-d-mannose for facile interaction with mannose receptors on dendritic cells (DCs) and for efficient delivery of immune stimulators to the DCs. The surface of the EXOs is modified with polyethylene glycol (PEG) without particle aggregation (\u224850 nm) via the incorporation of 1,2-distearoyl-sn-glycero-3-phosphoethanolamine (DSPE) into the lipid layer of the EXO, compared to chemical conjugation by N-hydroxysuccinimide activated PEG (NHS-PEG). PEG modification onto the exosomal surface significantly decreases the non-specific cellular uptake of the EXOs into the DCs. However, the EXOs with mannose-conjugated PEG-DSPE (EXO-PEG-man) exhibit excellent intracellular uptake into the DCs and boost the immune response by the incorporation of adjuvant, monophosphoryl lipid A (MPLA) within the EXO. After an intradermal injection, a higher retention of EXO-PEG-man is observed in the lymph nodes, which could be used for the efficient delivery of immune stimulators and antigens to the lymph nodes in vivo.\n\nID: 42572005\nTitle: Lymphatic Drainage of Cerebrospinal Fluid Using Lymph Node Seeker 64Cu-Labeled Gram-Negative Bacterial Extracellular Vesicles With Positron Emission Tomography (PET).\nAbstract: Cerebrospinal fluid (CSF) is drained into the systemic lymphatics via paravertebral lymph nodes. Superficial and deep cervical lymph nodes collect CSF in mice, but the exact and quantified routes are unknown. Recently, we simultaneously visualized cervical, sacral and iliac lymph nodes via serial imaging on the intrathecal [64Cu]Cu-albumin positron emission tomography. Paravertebral lymph nodes might act as sentinels to monitor the CSF, brain, and spinal cord. We used 64Cu-labeled Escherichia coli extracellular vesicles, outer membrane vesicles (OMVs), as lymph node seekers for intrathecal administration and quantified the differential amounts of various paravertebral lymph nodes along the axis of the brain and spinal cord in mice. The quantified results revealed 77.3% in superficial and deep cervical lymph nodes, 11.4% in abdominal/pelvic lymph nodes and 11.3% in sacral lymph nodes. Click-labeled [64Cu]Cu-OMVs were drained to reach and stop at the lymph nodes on serial quantification. The cervical lymph nodes drained most of the OMV-laden CSF, which is proportional to the surface areas of the brain (70%) and spinal cord in mice. We propose that all paravertebral lymph nodes monitor the segmental regions of the brain and spinal cord as immediate sentinel lymph nodes against the central nervous system.\n\nID: 42505363\nTitle: Exosomal EphA2 Promotes Gastric Cancer Progression by Inducing Phenotypic Transformation of Tumor Cells in a Ligand-Independent Manner.\nAbstract: The heterogeneity of tumor cells facilitates their dynamic adaptation to tumor microenvironmental pressures throughout progression. Nevertheless, the mechanisms underlying intercellular communication and transformation among heterogeneous tumor cells remain inadequately understood. In this study, we indicate that Ephrin type-A receptor 2 (EphA2) is heterogeneously expressed in gastric cancer (GC) tumor cells, with those exhibiting elevated EphA2 (EphA2High) expression demonstrating enhanced migratory and invasive capabilities. EphA2High cells facilitate the transfer of EphA2 via exosomes, which subsequently localize on the membrane of EphA2Low cells, thereby activating the ERK signaling pathway in a ligand-independent manner. This process promotes the transformation of EphA2Low cells and contributes to the progression of GC. An investigation into the correlation between serum levels and tumor metastasis in patients with GC revealed that those with lymph node metastasis exhibited higher levels of serum exosomal EphA2. This study elucidates the process of dominant group formation within heterogeneous tumor cells and suggests the viability of exosomal EphA2 as a potential biomarker for further clinical investigation.\n\nID: 42502396\nTitle: MZT2A drives epithelial-mesenchymal transition in lung adenocarcinoma via the LGALS3BP/ITGB1/TGF-\u03b2/smad2 axis.\nAbstract: The high mortality of lung adenocarcinoma (LUAD) is largely attributed to its metastatic propensity; therefore, elucidating novel mechanisms driving metastasis is crucial for developing diagnostic and therapeutic strategies. This study aimed to elucidate the function and mechanism of MZT2A in the metastasis of LUAD. Analysis of clinical samples and public databases revealed that MZT2A is highly expressed in LUAD tissues and significantly associated with lymph node metastasis, advanced stage, and poor prognosis. In vitro functional assays revealed that MZT2A overexpression significantly enhanced the invasion, migration, and adhesion of LUAD cells and induced epithelial-mesenchymal transition (EMT). Mechanistically, via its MOZART2 domain, MZT2A interacts with the SRCR domain of galectin-3-binding protein (LGALS3BP), promoting the sorting of LGALS3BP into exosomes and its subsequent secretion. Secretory LGALS3BP acts as a ligand, binding to integrin beta-1 (ITGB1) on the cell membrane through its BTB domain, thereby activating the downstream TGF-\u03b2/smad2 signaling pathway to drive EMT and metastatic phenotypes. Molecular docking and mutation experiments confirmed these critical domain interactions. In vivo experiments also validated that MZT2A overexpression promoted pulmonary metastasis, while LGALS3BP knockdown reversed this effect. Collectively, this study elucidated a novel \"MZT2A-LGALS3BP-ITGB1-TGF-\u03b2/smad2\" signaling axis that drives LUAD metastasis, providing a potential novel target for prognosis assessment and targeted therapy in LUAD.\n\nID: 42472387\nTitle: SFRP2+ CAFs Expressing Myofibroblastic Phenotype Are Involved in Glutamine Metabolism and Malignant Behaviors of Laryngeal Squamous Cell Carcinoma by Collaborating With ELAVL1 to Stabilize GID8 mRNA.\nAbstract: Metabolic reprogramming is a hallmark of cancer, enabling tumor cells to meet the demands of rapid growth and survival. Within tumor microenvironment (TME), cancer-associated fibroblasts (CAFs) influence tumor metabolism through metabolic crosstalk. However, role of CAF-derived factors in regulating glutamine metabolism in laryngeal squamous cell carcinoma (LSCC) remains unclear. Primary fibroblasts were isolated from LSCC tumors and adjacent tissues and classified as CAFs or normal fibroblasts (NFs). These were co\u2011cultured with LSCC cell lines to assess effects on proliferation, migration, invasion, stemness, and chemoresistance using assays such as CCK\u20118, EdU, sphere formation, Transwell migration/invasion, and real\u2011time RTCA assays. Exosomes were harvested from fibroblast-conditioned media, characterized by TEM, NTA, and Western blotting, and used to treat LSCC cells. Metabolic profiling included Seahorse measurements, TCA metabolites, ATP content, glutamine uptake ([3H]-glutamine assay), glutamine consumption, as well as glucose consumption and lactate production assays. Mechanistic studies involved manipulating gene expression via transfection, and detection of targets by qRT\u2011PCR, Western blotting, and histological staining. Interaction of SFRP2, ELAVL1, and GID8 was assessed via Co\u2011IP and RIP assays. SFRP2 was increased in LSCC and linked to advanced stage, lymph node metastasis, and poor survival. It was mainly produced by a unique group of CAFs with myofibroblastic traits. Exosomal SFRP2 from these CAFs promoted glutamine uptake, mitochondrial activity, and aggressive tumor behaviors. Mechanistically, SFRP2 stabilized GID8 mRNA via ELAVL1 and promoted \u03b2-catenin nuclear translocation, activating canonical Wnt signaling. A novel CAF-driven SFRP2-ELAVL1-GID8 pathway promotes metabolic reprogramming involving in LSCC progression.\n\nID: 42372209\nTitle: Development and Validation of Salivary Exosomal Tri-RNA Liquid Biopsy in Esophageal Carcinoma: A Multicenter Study.\nAbstract: Exosomal RNAs are emerging as cancer signatures, and saliva is a noninvasive biospecimen. Given the high mortality of patients with esophageal squamous cell carcinoma (ESCC) and limited early detection tools, we investigated a salivary exosome\u2011based Tri-signature for its diagnostic and prognostic potential. The salivary exosome\u2011based signature (ie, a chimeric RNA seG-NchiRNA, a tRNA fragment GlyGCC-5, and a novel sRESE RNA) was quantified by qRT-PCR in a multicenter observational study across two ESCC-endemic regions. Model development and validation were performed in the training (n = 359) and validation (n = 225) cohorts using logistic regression, survival analyses, and Shapley Additive exPlanations-based feature interpretation. The Tri-signature showed excellent diagnostic accuracy (training cohort: AUC, 0.987; validation cohort: AUC, 0.964) and robust prognostic value (training cohort: overall survival [OS] hazard ratio [HR], 5.52, progression-free survival [PFS] HR, 4.46; validation cohort: OS HR, 4.76, PFS HR, 2.79). In the high Combined Risk Score for Prognosis (CRSP) subgroup, patients with relatively lower CRSP derived significant benefit from adjuvant therapy (training cohort: OS HR, 0.54, PFS HR, 0.47; validation cohort: OS HR, 0.38, PFS HR = 0.32), whereas no such benefit was observed in low Tri-signature patients. The Tri-signature exhibited strong early diagnostic performance, distinguishing early-stage ESCC without lymph node metastasis from healthy controls (training cohort: AUC = 0.975; validation cohort: AUC = 0.950). Patients with early-stage ESCC and high CRSP had significantly worse outcomes (training cohort: OS HR, 5.09, RFS HR, 3.80; validation cohort: OS HR, 8.79, RFS HR, 4.55). The salivary exosome-based tri-RNA signature showed robust multicenter reproducibility and strong diagnostic, prognostic, and treatment response-predictive performance, supporting its translational potential as a noninvasive biomarker panel for ESCC management.\n\nID: 42338756\nTitle: Red ginseng-derived nanovesicles to modulate osteoblast and osteoclastogenesis for osteoporosis therapy.\nAbstract: Osteoporosis is a skeletal disorder characterized by an imbalance between bone formation and resorption, which leads to progressive bone loss and increased fracture risk. While current treatments either inhibit bone resorption or stimulate bone formation, their long-term use is associated with adverse effects, necessitating alternative therapeutic approaches. In this study, we explore the use of red ginseng-derived nanovesicles (RGNVs) as a biocompatible nanotherapeutic strategy for treating osteoporosis. The RGNVs were successfully isolated and characterized, revealing a lipid bilayer structure enriched in bioactive ginsenosides and functional proteins. In vitro, RGNVs enhanced osteoblast proliferation, differentiation, and mineralization while suppressing osteoclast differentiation and bone resorption by modulating the BMP-2/Smad and MAPK signaling pathways. In an ovariectomy-induced osteoporosis mouse model, oral administration of RGNVs significantly restored bone volume and mineral density, and biodistribution studies confirmed their preferential accumulation in the bone tissue. Systemic toxicity evaluation indicated no adverse effects, supporting the safety of RGNVs for therapeutic use. These findings suggest that RGNVs regulate bone remodeling through a dual mechanism, to stimulate bone formation and inhibit bone resorption, thereby offering a promising and well-tolerated approach for osteoporosis management.\n\nID: 42293730\nTitle: A safe and anti-inflammatory plant-derived nanovesicle platform for targeted delivery in acute lung injury.\nAbstract: Acute lung injury (ALI) and its more severe form, acute respiratory distress syndrome (ARDS), are life-threatening pulmonary disorders with extremely high mortality rates, for which effective and safe therapeutic strategies remain limited. The development of targeted and biocompatible drug delivery systems is urgently needed to control pulmonary inflammatory cascades while minimizing systemic toxicity. Plant-derived extracellular vesicles offer a naturally safe and anti-inflammatory platform for therapeutic delivery. Ginsenoside Rb1 (GRb1), a major bioactive compound from ginseng, possesses potent anti-inflammatory and anti-apoptotic properties, whereas lemon-derived EVs (LEVs) exhibit intrinsic antioxidant and anti-inflammatory effects. Here, we engineered a multifunctional, biocompatible drug delivery platform, GRb1@LEVs-cRGD, in which ginsenoside Rb1 is incorporated into and fused with LEVs to form hybrid bio-nanovesicles, while the vesicle surface is functionalized with cyclic RGD (cRGD) peptides to target integrin \u03b1v\u03b23 highly expressed in inflamed pulmonary tissues, thereby enhancing site-specific delivery. In vitro and in vivo studies confirmed that GRb1@LEVs-cRGD effectively inhibited M1 macrophage polarization, suppressed inflammatory cascades, and preserved epithelial-endothelial integrity. Furthermore, exogenous cholesterol loading improved vesicle stability, maintained the pH gradient, and enhanced the loading efficiency of tigecycline and vancomycin by six-fold. In murine models of bacterial pneumonia induced by carbapenem-resistant Klebsiella pneumoniae and methicillin-resistant Staphylococcus aureus, antibiotic-loaded GRb1@LEVs-cRGD efficiently accumulated at infection sites and exhibited synergistic anti-inflammatory and bactericidal effects. Overall, this study demonstrates that GRb1@LEVs-cRGD is a safe, targeted, and multifunctional therapeutic platform with significant potential for ALI/ARDS treatment.\n\nID: 42238572\nTitle: Exosomal POSTN from cancer-associated fibroblasts drives progression of microinvasive lung adenocarcinoma: insights from single-cell and tissue exosome sequencing analysis.\nAbstract: Microinvasive adenocarcinoma (MIA) represents an early stage of lung adenocarcinoma (LUAD), yet how the tumor microenvironment (TME) and cancer-associated fibroblast (CAF)-derived exosomes contribute to its progression remains unclear. We aimed to define the cellular ecosystem of MIA and to clarify the role of periostin (POSTN) and POSTN+ CAF-derived exosomes in early LUAD progression. Single-cell RNA sequencing (scRNA-seq) and tissue-derived exosomal RNA sequencing were performed on four primary MIA lesions and matched adjacent lung tissues. Integrated analyses of scRNA-seq data, exosomal transcriptomes, the TCGA-LUAD cohort, and an independent LUAD tissue/serum cohort were used to characterize POSTN expression and to evaluate its prognostic and diagnostic relevance. Primary MIA-associated POSTN+ and POSTN- CAFs were isolated for exosome preparation, followed by co-culture experiments with LUAD cell lines and xenograft assays. scRNA-seq identified a malignant Cancer-alveolar type II (Cancer-AT2) epithelial subset and multiple CAF subsets. Among these, POSTN+ CAFs were enriched in MIA tissues and showed enhanced crosstalk with Cancer-AT2 cells through extracellular matrix (ECM)-related ligand-receptor interactions. Tissue-derived exosomes contained 588 differentially expressed mRNAs, among which POSTN was markedly upregulated and showed the strongest association with fibroblast-related signatures. POSTN was predominantly expressed in fibroblasts across independent non-small cell lung cancer datasets and was elevated in LUAD tissues, tissue-derived exosomes, and serum exosomes, correlating with advanced stage, lymph node metastasis, and poor survival. Functionally, POSTN+ CAF-derived exosomes promoted LUAD cell proliferation, migration, invasion, colony formation, and xenograft growth. Exosomal POSTN derived from POSTN+ CAFs may represent an important stromal mediator of MIA/LUAD progression and a potential diagnostic and prognostic biomarker in early-stage LUAD.\n\nID: 42207394\nTitle: The ginger-derived nanovesicles-coated albumin nanoparticles induce cell death and epigenetic regulation to treat colorectal cancer.\nAbstract: Due to the limitations of conventional cancer chemotherapy, including low bioavailability, limited indicators of therapeutic improvement, and unclear side effects, numerous laboratories have been actively engaged in the development of drug delivery systems. Here, we designed and synthesized a plant-derived ginger exosome-coated albumin nanoparticle drug delivery system (GEBSS) loaded with Shikonin (SHK) and STM2457 (a METTL3 inhibitor) and probes into the mechanism of antitumor. We prepared and characterized GEBSS nanoparticles and evaluated their in vitro cellular uptake and targeting capabilities. The in vitro antitumor efficacy was assessed by measuring cell viability, clonogenic formation, oxidative stress, mitochondrial function, and apoptosis markers; biosafety was confirmed via a hemolysis assay. Furthermore, the ability of GEBSS to induce ICD was validated through Western blotting, ATP detection, and immunofluorescence assays, while its role in epigenetic regulation was elucidated using Dot Blot, MeRIP-qPCR, and RNA stability experiments. Finally, the in vivo antitumor effect of GEBSS was verified by intravenous administration in a nude mouse subcutaneous tumor model. A subsequent characterization revealed that GEBSS exhibited a concentrated size distribution around 142\u00a0nm, were efficiently absorbed by colorectal cancer (CRC) cells, and demonstrated inhibitory effects on tumor cell proliferation. In vivo experiments demonstrated excellent tumor-targeting ability, anti-tumor efficacy, and biocompatibility of GEBSS. Mechanistically, GEBSS induced apoptosis and immunogenic cell death (ICD) in tumor cells. Moreover, at the epigenetic regulation level, GEBSS suppressed cell proliferation by reducing the m6A methylation levels of immune checkpoint genes PD-L1 and CD47. This study explored the feasibility of producing naturally derived nanocarriers and, for the first time, employed a combination of SHK and STM2457 for CRC treatment, offering novel strategies and insights for nanomedicine in CRC treatment.\n\nID: 42131580\nTitle: Tumor-Derived Exosomal PDLIM1 Promotes Angiogenesis and Tumor Progression in Papillary Thyroid Carcinoma: Insights From Integrated Single-Cell Transcriptomics and Exosomal Proteomics.\nAbstract: Papillary thyroid carcinoma (PTC) with metastatic potential presents a complex and poorly understood tumor microenvironment. Despite its clinical significance, the cellular and molecular mechanisms driving metastatic progression remain inadequately characterized, particularly the role of intercellular communication mediated by tumor-derived exosomes. We analyzed single-cell RNA sequencing (scRNA-seq) on primary and metastatic PTC tissues (n=12 samples from 4 patients), exploring cellular heterogeneity and distinct subpopulations. Metastasis-associated cell states (Scissor+ and Scissor-) were delineated using the Scissor algorithm. Pathway activity in these subpopulations was analyzed using the PROGENy algorithm.Exosomal proteomic data from lymph node metastasis patients were cross-referenced with Scissor+ signatures, identifying candidate proteins. Functional validation included in vitro angiogenesis assays with HUVECs and in vivo xenograft models to assess tumor growth and vascularization. ScRNA-seq revealed significant tumor cell heterogeneity between primary and metastatic sites, with Scissor+ cells strongly linked to metastatic phenotypes. PROGENy analysis demonstrated significant upregulation of VEGF signaling in Scissor+ cells. Among six key proteins identified, PDLIM1 was highly expressed in PTC cell lines and metastatic tissues (P < 0.001). Tumor-derived exosomal PDLIM1 was internalized by endothelial cells, enhancing angiogenesis in vitro. PDLIM1 knockdown in exosomes suppressed HUVEC tube formation (P < 0.05) and reduced tumor volume, CD31+ microvessel density, and LYVE-1+ lymphatic vessel density in xenografts (P < 0.05). Our study suggests that exosomal PDLIM1 may play a role in promoting angiogenesis and primary tumor progression in PTC. These findings provide preliminary insights into the potential involvement of exosome-mediated intercellular communication in PTC pathogenesis. Further validation in larger cohorts and functional studies, including rescue experiments, are warranted to evaluate whether targeting PDLIM1 could represent a viable therapeutic strategy.\n\nID: 42112125\nTitle: Therapeutic potential of panax ginseng-derived nanovesicles in osteoporosis through enhanced osteoblast.\nAbstract: Osteoporosis is a skeletal disorder caused by an imbalance between bone resorption and formation, which leads to reduced bone density and increased fracture risk. Plant-derived nanovesicles have emerged as safe, biocompatible biomaterials with therapeutic potential for bone regeneration. In this work, the biological effects of Panax ginseng-derived nanovesicles (PNVs) were evaluated with a focus on osteoblast differentiation, bone formation, and mineralization. PNVs were successfully isolated, characterized, and tested for their osteogenic capacity using MC3T3-E1 cells, mouse primary osteoblasts, and osteoclasts. Treatment with PNVs (0-10\u00a0\u03bcg/mL) for 3 or 7 days markedly promoted osteoblastic maturation and matrix mineral deposition, as confirmed by Alizarin-red and Von Kossa staining. In addition, PNVs exposure upregulated key osteogenic genes, including Runx2, ALP, and OPN, while activating major signaling cascades such as BMP2/4 and phosphorylated p38, implying their involvement in osteogenic regulation. Moreover, in an ovariectomized (OVX) mouse model, oral administration of PNVs improved bone microarchitecture by stimulating osteoblast-driven bone regeneration and attenuating osteoclast-mediated bone degradation. Collectively, our findings indicate that PNVs promote osteoblast differentiation and bone matrix formation, thereby enhancing mineralization and demonstrating their potential as a natural nanotherapeutic approach for osteoporosis prevention and treatment.\n\nID: 41965227\nTitle: Unlocking the potential of serum exosomal PIWI-interacting RNAs as diagnostic biomarker for endometrial cancer.\nAbstract: Endometrial cancer is a common gynecological cancer with a rising incidence, yet effective non-invasive early diagnostic methods are lacking. Recent findings indicate that tumor-derived exosomal cargo, including PIWI-interacting RNAs (piRNAs), may serve as promising cancer-specific biomarkers. Our study investigates the potential of serum-derived exosomal piRNAs for early detection of endometrial cancer. Biomarker development involves 3 phases with independent patient cohorts. In the discovery phase, small RNA sequencing identified candidate exosomal piRNAs from serum samples of 5 healthy controls and 6 patients with endometrial cancer. In the training phase, a serum exosomal piRNA panel was created using receiver operating characteristic curve, logistic regression, a random forest algorithm, and the DeLong test. In the validation phase, we verified the diagnostic performance of the 3piRNA_panel using the receiver operating characteristic curve. In validation, the 3piRNA_panel (hsa_piR_009183, hsa_piR_014592, and hsa_piR_006767) showed high diagnostic accuracy for endometrial cancer, with an area under the curve of 0.942. It distinguished stage IA endometrial cancer from healthy controls with an area under the curve of 0.977 and was effective in patients with normal CA125 levels. It also potentially differentiated stage IA endometrial endometrioid carcinoma from atypical endometrial hyperplasia. A post-operative decrease in panel scores was observed in a limited subset of paired samples. The expression of hsa_piR_014592 was significantly associated with aggressive histopathological types, \u226550% myometrial invasion, substantial lymphovascular space invasion, lymph node metastasis, p53 mutation, and G3 endometrial endometrioid carcinoma. Our novel non-invasive serum exosomal piRNA panel demonstrated clinical potential for the early detection of endometrial cancer.\n\nID: 41824788\nTitle: Tumor-Derived Exosomal TAGLN2 Promotes Metastasis by Inducing Vascular Permeability and Angiogenesis via the NRP1/SEMA4D/YAP Axis.\nAbstract: Tumor-derived exosomes critically mediate metastasis, yet how specific cargoes reprogram the vasculature remains unclear. In gastric cancer (GC), we identify TAGLN2 as a key exosomal mediator. It is co-overexpressed in GC cells and tumor-associated endothelial cells (TECs), and its high endothelial expression correlates with lymph node metastasis and poor prognosis. Functionally, GC-derived exosomes deliver TAGLN2 to endothelial cells (ECs), orchestrating angiogenesis, EndoMT, and the disruption of endothelial junctions. In vivo, exosomal TAGLN2 accelerated tumor growth and lung metastasis by generating abnormal, leaky vasculature and hypoxia. Mechanistically, exosomal TAGLN2 initiates a novel signaling axis: it transcriptionally upregulates NRP1 via c-Jun/SP1 and concurrently induces SEMA4D expression. TAGLN2 then interacts with both NRP1 and SEMA4D to nucleate a stable cytoplasmic ternary complex. This complex dually activates YAP by competitively disrupting NRP1-YAP binding to release YAP from cytoplasmic retention, and simultaneously suppressing Hippo-mediated degradation, operating independently of the canonical SEMA4D-PlexinB1-RhoA/ROCK pathway. Therapeutically, targeting the TAGLN2 axis synergized with both cisplatin and bevacizumab, potently suppressing tumor progression by impairing neovascularization and promoting vascular normalization. Clinically, exosomal TAGLN2 levels were significantly elevated in GC patient serum. Our study delineates a complete exosome-to-vasculature signaling axis and positions TAGLN2/NRP1/SEMA4D/YAP module as an integrated diagnostic and therapeutic target against metastatic GC.\n\nID: 41790367\nTitle: Serum Exosomal Hsa_circ_0005692 as A Novel Biomarker for Colorectal Cancer Metastasis: A Retrospective Observational Study.\nAbstract: Background. Increasing evidence suggests that exosomal circular RNAs (circRNAs) could serve as promising novel biomarkers for colorectal cancer (CRC) detection. However, diagnostic potential of exosomal circRNAs in CRC metastasis remain largely underexplored. Methods. The differentially expressed circRNAs (DEcircRNAs) were screened through GSE159669 and GSE205643 datasets. Seventy patients with CRC and seventy age- and sex-matched healthy controls were retrospectively enrolled in this study. The expression of DEcircRNAs was validated in paired cancer and paracancerous tissues, as well as in serum and serum-derived exosomes by RT-qPCR. The clinical significance, prognostic, and diagnostic efficacy of DEcircRNAs were evaluated through chi-square test, Kaplan-Meier survival curves, Cox regression model analysis, and receiver operating characteristic curves. The effect of DEcircRNAs on CRC cell migration and invasion was assessed through wound healing and transwell assays with gain- and loss-of-function methods. Results. A total of six DEcircRNAs were identified, among which only hsa_circ_0005692 exhibited consistent upregulation in cancer tissues, serum, and serum-derived exosomes from patients with CRC. Increased exosomal hsa_circ_0005692 was positively associated with lymph node metastasis and distant metastasis. Patients with elevated levels of exosomal hsa_circ_0005692 exhibited lower overall survival and progression-free survival rates, and exosomal hsa_circ_0005692 was identified as an independent risk factor for poor overall survival. Notably, exosomal hsa_circ_0005692 showed superior diagnostic accuracy than its expression in tissues and serum counterparts in differentiating not only CRC patients from healthy controls, but also metastatic patients from non-metastatic patients. Moreover, hsa_circ_0005692 was found to facilitate CRC metastasis by promoting cell migration and invasion as well as epithelial-mesenchymal transition. Conclusion. This study provides preliminary evidence that serum exosomal hsa_circ_0005692 may serve as a potential biomarker for predicting metastasis in CRC patients, and functionally facilitates CRC metastasis. However, larger-scale confirmatory studies and external validation are still required to substantiate this conclusion.\n\nID: 41580383\nTitle: Diagnostic and prognostic potential of salivary microRNA in oral and head and neck squamous cell carcinomas: a systematic review.\nAbstract: Oral squamous cell carcinoma (OSCC) and head and neck squamous cell carcinoma (HNSCC) are aggressive malignancies with poor survival rates, largely attributable to late diagnosis. Salivary microRNAs (miRNAs), particularly exosome-derived miRNAs, have emerged as promising non-invasive biomarkers for early detection and prognostic assessment. This systematic review evaluated the diagnostic and prognostic value of free and exosomal salivary miRNAs in OSCC and HNSCC. A comprehensive search of PubMed, Scopus, Web of Science, and Google Scholar was conducted for studies published between January 2008 and May 2025. Studies assessing salivary miRNAs in histologically confirmed OSCC/HNSCC using validated molecular techniques were included, with quality assessed using QUADAS-2. Forty-two studies encompassing 2577 patients/samples were analyzed. Several miRNAs, including miR-21, miR-31, miR-1307-5p, and miR-486-5p, demonstrated high diagnostic accuracy (AUC > 0.85), while others were significantly associated with lymph node metastasis, treatment response, and survival outcomes. Exosomal miRNAs generally showed superior stability and predictive performance compared with free miRNAs. However, substantial methodological heterogeneity was observed. Overall, salivary miRNAs-particularly exosomal-represent promising biomarkers for OSCC and HNSCC, although standardized protocols and large-scale validation studies are required for clinical translation.\n\nID: 41184439\nTitle: Evaluation of salivary and serum Exosomal mRNAs as biomarkers for the diagnosis and prognosis of oral squamous cell carcinoma.\nAbstract: Minimally-invasive or non-invasive biomarkers from serum and saliva hold significant promise for real-time monitoring of oral squamous cell carcinoma (OSCC). However, the diagnostic potential of exosomes, which carry heterogeneous tumor-derived functional cargo remains largely underexplored. This study aimed to evaluate the diagnostic and prognostic utility of exosomal mRNAs derived from saliva and serum samples of OSCC patients. Exosomes were isolated from paired serum and saliva samples of 40 OSCC patients and 40 healthy controls using commercial kits. Characterization was performed using NTA, TEM, zeta potential, protein/lipid quantification, and western blotting. Expression of nine mRNA markers including cytokines (IL1, IL6, IL8, TNF-\u03b1), proliferation markers (OAZ1, SAT, S100P), and metastasis-related molecules (MMP9, Chemerin) was analyzed by qRT-PCR. Diagnostic accuracy was evaluated using ROC curve analysis, and correlations with tumor grade and lymph node metastasis were systematically investigated. Results demonstrated that salivary exosomal TNF-\u03b1,\u00a0MMP9 and OAZ1 exhibited markedly higher diagnostic sensitivity and specificity compared to the top-performing serum exosomal derived markers (IL1, MMP9\u00a0and OAZ1). Notably, a two-gene salivary mRNA panel combining TNF-\u03b1 and OAZ1 demonstrated strong discriminatory power (AUC: 0.89, sensitivity: 80%, specificity: 90%; Youden Index: 0.70). Additionally, salivary exosomal MMP9, IL8, S100P, SAT, and OAZ1 significantly differentiated between grade I and grade III OSCC. Moreover, IL6 expression positively correlated with lymph node metastasis. In contrast, serum exosomal markers lacked clear discriminatory potential. Therefore, salivary exosomal panel of TNF-\u03b1 and OAZ1 represent promising non-invasive biomarkers for OSCC diagnosis, while MMP9 and IL6 is informative for tumor grading.\n\nID: 41183156\nTitle: Exosomal miR-155-5p Modulates Breast Cancer Proliferation and Metastasis Via NF-\u03baB Activation.\nAbstract: Breast cancer (BC) represents a major contributor to cancer-associated deaths among women, underscoring the need for novel therapeutic approaches. This study explores the role of miR-155-5p as an oncogenic driver in BC progression through a multi-omics approach. Elevated miR-155-5p expression was observed in serum exosomes and tumor tissues, with its upregulation correlating with advanced pathological stages, lymph node metastasis, and unfavorable clinical outcomes. Functional experiments demonstrated that miR-155-5p enhances cellular proliferation, motility, and invasive capacity while inhibiting apoptosis in BC. Mechanistically, miR-155-5p exerts its effects by directly suppressing Nedd4 Family Interacting Protein 1 (NDFIP1), thereby initiating activation of the NF-\u03baB axis. This activation was characterized by increased nuclear translocation of NF-\u03baB p65 and enhanced secretion of inflammatory cytokines, including IL-6 and TNF-\u03b1. In vivo, knockdown of miR-155-5p effectively suppressed tumor growth and metastasis, with these effects reversed by silencing NDFIP1. These results highlight the miR-155-5p/NDFIP1/NF-\u03baB axis as a critical pathway in BC progression, providing new insights into its molecular mechanisms. miR-155-5p emerges as a promising diagnostic marker and therapeutic candidate, suggesting the feasibility of miRNA-based interventions in BC treatment. This study highlights the pivotal role of integrative omics technologies in uncovering cancer-related regulatory networks.\n\nID: 41103032\nTitle: Extracellular vesicles are key mediators for direct antigen transport to draining lymph nodes.\nAbstract: DNA vaccines have shown great potential in preclinical and clinical studies. However, it is still unclear how the antigen expressed at the site of vaccination is delivered to draining lymph nodes for activation of the immune system. To address the issue, the current study investigated the role of extracellular vesicles (EVs) in the delivery. Following intramuscular electrotransfection of DNA vaccines encoding a transmembrane antigen, hemagglutinin (HA), EV secretion was significantly increased in the muscle with the peak level being \u223c10-fold higher than the unvaccinated control. More importantly, the EVs were highly enriched with HA, and could reach the draining lymph nodes through lymphatic vessels within 4 h. Blocking the EV secretion by systemic treatment with a small molecular inhibitor, GW4869, significantly reduced humoral and cellular responses against the antigen. These findings indicated that the EVs play an important role in the antigen delivery, suggesting that enhancing local EV biogenesis and antigen packaging into EVs can be new avenues for development of next-generation vaccine adjuvants.\n\nID: 42649785\nTitle: A Scalable Bioreactor Platform for Reproducible Production and Characterization of Ovarian Cancer-Derived Extracellular Vesicles.\nAbstract: Extracellular vesicles (EVs) from ovarian cancer cells are valuable sources for candidate biomarker studies, but conventional static flask culture yields limited material and is difficult to scale reproducibly. We evaluated a serum-free CELLine AD 1000 bioreactor workflow for producing EVs from four ovarian cancer-related (OC-related) cell lines (OVCAR4, CaOV3, PA1, SW626) and human dermal fibroblasts (HDFa) as a non-cancer control. Cells were adapted to CDM-HD serum-free medium and maintained for eight weeks with twice-weekly conditioned-medium collection. EVs were isolated by differential ultracentrifugation followed by size-exclusion chromatography and characterized by nanoparticle tracking analysis, imaging flow cytometry, Western blotting, and transmission and scanning electron microscopy. Across longitudinal harvests, OC-related cultures generally produced higher EV particle concentrations and A280-based bulk protein estimates than HDFa, while individual cell lines showed distinct production profiles and membrane-associated growth patterns. A parallel OVCAR4 T-175 flask, maintained in its original serum-containing medium, provided a contextual reference indicating higher per-collection EV particle recovery with the bioreactor, although this was not a matched culture-format comparison. EV-enriched preparations contained vesicle-like particles, with modal diameters of approximately 96-128 nm. Using imaging flow cytometry, the CD9 signal was higher in OC-related EVs and CD63 was most prominent in HDFa; CD9 and CD63 were also detected in OC-related EV lysates by Western blotting. Because one bioreactor was operated per cell line, these findings should be interpreted as preliminary and descriptive rather than statistically comparative. Overall, this study provides a practical serum-free CELLine AD 1000 workflow for generating characterized OC-related EV material for downstream analytical studies.\n\nID: 42634544\nTitle: Effects of Human Hair Outer Root Sheath Cell- and Human Bone Marrow Mesenchymal Stem Cell-Derived Exosomes on Human Hair Follicle Stem Cells.\nAbstract: The cyclical growth of hair follicles depends on the periodic proliferation and differentiation of hair follicle stem cells (HFSCs). Previous studies have shown that extracellular vesicles (EVs) derived from mesenchymal stem cells (MSCs) and human hair outer root sheath cells (HHORSCs) can enhance hair follicle development, ameliorate androgenetic alopecia, and support the inductive capacity of dermal papilla cells. However, the regulatory effects of HHORSC-derived EVs (HHORSC-EVs) and human bone marrow mesenchymal stem cell-derived EVs (HBMMSCEVs) on HFSCs remain unclear. HFSCs were treated with HHORSC-EVs or HBMMSC-EVs for 10 days. The effects of EVs on HFSC proliferation, apoptosis, and differentiation were evaluated using a Cell Counting Kit8 assay, flow cytometry, and immunofluorescence staining, respectively. EVs from both HHORSCs and HBMMSCs did not enhance hair follicle growth by improving the proliferation of HFSCs, but rather by inhibiting apoptosis. In addition, HBMMSC-EVs further promoted HFSC stemness maintenance by upregulating K15 and CD34 expression. HFSCs may serve as a novel target for both HHORSC-EVs and HBMMSC-EVs, highlighting their therapeutic potential for hair loss disorders. This study offers new insights into developing EV-based therapies for hair loss disorders.\n\nID: 42628189\nTitle: Hair regeneration in alopecia using adipose-derived mesenchymal stem cells secretome: A systematic review of experimental and clinical evidence.\nAbstract: Alopecia is characterized by progressive follicular miniaturization and impaired regenerative capacity associated with abnormal hair cycling. Current therapies often provide limited or temporary benefits, highlighting the need for regenerative strategies targeting follicular restoration. This systematic review summarizes current experimental and clinical evidence regarding the regenerative potential of the secretome from adipose tissue-derived mesenchymal stem cells (AT-MSCs) as a cell-free therapeutic strategy for hair regeneration. In contrast to conventional cell transplantation, the biological effects of AT-MSCs secretome are mainly mediated through paracrine mechanisms involving a variety of bioactive molecules, including growth factors, cytokines, and extracellular vesicles such as exosomes. Evidence from experimental models indicates that treatment with MSCs-derived secretome supports dermal papilla cell expansion and triggers intracellular signaling mechanisms that regulate hair follicle growth, with the Wnt/\u03b2-catenin pathway playing a major role. In preclinical animal studies, administration of the secretome has been shown to accelerate the transition of hair follicles from the telogen phase to the anagen phase, accompanied by increased follicle density and improved perifollicular vascular development. Preliminary clinical findings also suggest improvements in hair density and hair shaft thickness, especially when secretome therapy is applied together with microneedling procedures or standard therapeutic approaches. The observed regenerative responses are believed to be mediated by several angiogenic growth factors, including vascular endothelial growth factor (VEGF), insulin-like growth factor-1 (IGF-1), and hepatocyte growth factor (HGF). In addition, these effects involve signaling pathways that regulate immune responses and inhibit apoptosis within the follicular microenvironment. However, variations in secretome production techniques, dosage approaches, and clinical research design restrict the interpretation of available data. Validating the safety, effectiveness, and therapeutic significance of AT-MSCs secretome in the treatment of alopecia requires extensive, well-controlled clinical trials and established manufacturing procedures.\n\nID: 42594253\nTitle: Adipose stem cell vesicles reduce bleomycin-induced dermal fibrosis and oxidative stress in scleroderma mice via circ-Zfyve9.\nAbstract: Systemic sclerosis (SSc) is an autoimmune condition affecting several organs. It is identified by thickening of the dermis, connective tissue affected by collagen accumulation, and vascular injuries that induce hypoxia. The present study aimed to determine whether extracellular vesicles (EVs) from adipose-derived stem cells (ADSCs) attenuated bleomycin-induced skin fibrosis and oxidative stress in scleroderma. ADSCs and their EVs were separated and a bleomycin-induced SSc mouse model was constructed. High-throughput sequencing was employed to study abnormal expression of circular RNAs in SSc skin tissues with or without ADSC-EV treatment. The regulatory mechanism and targets were studied using bioinformatics analysis, luciferase reporting analysis, angiogenic differentiation experiments, and RT-qPCR detection analysis. EVs from ADSCs were successfully isolated. The exosome treatment prevented dermal thickening and fibrosis in bleomycin-induced scleroderma. In addition, circ-Zfyve9 was demonstrated to have an important function in ADSC-EV-mediated skin tissue protection. GPX4 and miR-135 were shown to be downstream targets of circ-Zfyve9. Overexpressing miR-135 or downregulating GPX4 reversed the promotion effects of circ-Zfyve9 on angiopoiesis by increasing lipidosome ROS in EPCs under hypoxic conditions. Overexpressing miR-135 or downregulating GPX4 reversed the inhibition effect of circ-Zfyve9 on fibrosis in myofibroblasts under hypoxic conditions. Overexpressing circ-Zfyve9 increased the therapeutic effect of ADSC-EVs. EVs from ADSCs attenuated bleomycin-induced skin fibrosis and oxidative stress in scleroderma via circ-Zfyve9 delivery.\n\nID: 42578151\nTitle: Platelet Products and Artificial Platelets for Regenerative Medicine.\nAbstract: Platelet products derived from whole blood include platelet-rich plasma (PRP), platelet-rich fibrin (PRF), platelet lysate (PL), and platelet-derived extracellular vesicles (pEVs). Such products have been utilized for hemostatic purposes and regenerative medicine. Poor shelf life, high cost of storage, immune risk, and constant need for adequate donors have led to the desire for biomaterials that mimic platelet function. Artificial platelets, such as platelet-membrane coated nanoparticles (NPs), platelet-like particles, SynthoPlate, and GRGDS-PEG-coated polyurethane NPs, have been designed to mimic platelet functionality and aid in hemostasis. Platelet product and artificial platelet function can be further leveraged for regenerative medicine and wound healing as they interact with activated platelets and fibrin at the region of interest, highlighting their therapeutic potential. Example regenerative applications of both platelet products and artificial platelets include osteogenesis, angiogenesis, soft tissue and dermal healing, and drug or cell delivery. Some platelet products have reached clinical trials, but most of the biomaterial based approaches are still in preclinical testing. Research into their regenerative and wound healing capabilities is novel for the field, but the products show tremendous promise in biomedical applications beyond hemostasis.\n\nID: 42571998\nTitle: Rituximab Binding Endows CD20+ Extracellular Vesicles With NK Cell-Activating Properties in B Cell Lymphoma.\nAbstract: Non-Hodgkin lymphoma (NHL), predominantly B cell lymphomas (B-NHL), is currently treated with chemotherapy combined with rituximab (RTX), an anti-CD20 monoclonal antibody. Despite substantial therapeutic advances, treatment resistance and disease relapse continue to affect a significant fraction of patients. The mechanisms by which the tumour microenvironment and other factors influence RTX efficacy are not fully elucidated. Herein, we hypothesized that CD20+ extracellular vesicles (EVs) shed by B cell lymphomas are recognized by RTX forming immune complexes that modulate natural killer (NK) cell activity via Fc\u03b3 receptor (Fc\u03b3R) interactions. EVs isolated from lymph node explants and plasma samples of B-NHL patients contained abundant CD20+ vesicles, which were particularly enriched in advanced disease. RTX specifically bound CD20 on these EVs, generating EV-RTX immune complexes. Functional studies employing EVs from a B-NHL cell line and from patient-derived samples demonstrated that, whereas EVs suppressed NK cell activation and cytotoxicity, EV-RTX immune complexes reversed this inhibitory effect and enhanced NK cell effector functions. Indeed, EV-RTX immune complexes specifically triggered Fc\u03b3RIIIa-dependent NK cell activation, evidenced by increased Syk phosphorylation, CD69 expression, and enhanced lytic activity against target cells. Our findings uncover a previously unrecognized mechanism by which RTX, through the formation of immune complexes with CD20+ EVs, promotes NK cell activation and may enhance therapeutic efficacy. More broadly, these results demonstrate that antibody binding can endow EVs with novel immunomodulatory properties, revealing a potential mechanism by which therapeutic antibodies reshape EV function and influence anti-tumour immunity.\n\nID: 42554772\nTitle: Osteocyte-vascular Interactions in Bone Physiology and Pathology.\nAbstract: Through their extensive lacuno-canalicular network, osteocytes act as key regulators of bone remodelling and have more recently been recognized as contributors to bone repair. However, these processes occur in a highly vascularized tissue, and the relationship between osteocytes and bone vasculature remains poorly understood. This review summarizes current knowledge on osteocyte-vascular interactions, with a focus on communication mechanisms and their relevance to bone physiology, aging, and disease. Emerging evidence indicates that osteocyte-vascular communication occurs through several modalities. Indirect signalling involves paracrine factors secreted by osteocytes, including VEGF, sclerostin, neuropeptide Y, as well as extracellular vesicles, which modulate ECs' behaviour. Direct communication has also been suggested through physical interactions between osteocytes and blood vessels, including mitochondrial transfer and potentially gap junctions. Recent studies have also identified lymphatic vessels within bone, raising the possibility of previously unrecognized interactions between osteocytes and the lymphatic vasculature. Together, these findings highlight diverse modes of communications and associated signalling pathways, through which osteocytes may regulate vascular function within bone. Despite emerging insights into osteocyte-bone vasculature crosstalk, the underlying mechanisms remain incompletely understood. Advances in experimental tools may improve our knowledge of this bidirectional dialogue, providing new perspectives on bone physiology, skeletal pathologies, and potential therapeutic strategies targeting this interaction.\n\nID: 42543715\nTitle: The Role of dWAT-Immune Crosstalk in Hair Follicle Microenvironment in Hair Regeneration.\nAbstract: The hair follicle microenvironment is the core functional unit of hair regeneration. dWAT (Dermal white adipose tissue) is an indispensable component of this microenvironment. Rather than serving as a passive filler, dWAT, through multidimensional mechanisms including cytokines, metabolites, extracellular vesicles, and cell-cell interactions, forms a complex regulatory network with local immune cells and exerts unique immune functions. It is deeply involved in the maintenance of local immune homeostasis, the regulation of the inflammatory response, and hair regeneration. In this review, we summarize the latest research on the effect of adipose-immune interactions on hair growth within the hair follicle microenvironment, focusing on how the dWAT surrounding the hair follicle serves as the foundation of the local adipose-immune interaction microenvironment, and on the regulatory mechanisms by which the immune function of hair follicle dWAT influences hair follicle regeneration. The dynamic remodeling of dWAT along the hair follicle cycle provides key metabolic support for the formation and regulation of the immune microenvironment around the hair follicle, and also constitutes the material basis for the crosstalk among immune cells within the hair follicle. The interaction between dWAT and immune cells affects the hair follicle growth process by regulating the local inflammatory response, immune cell phenotypic switching, and associated signaling pathways.\n\nID: 42511549\nTitle: Telocytes Twenty Years on: A Critical Reappraisal of Identity, Function, and Pathological Relevance.\nAbstract: Telocytes are stromal cells defined by extremely long, moniliform prolongations termed telopodes and have been described in most mammalian organs since their formal designation in 2010. During the past two decades, the field has expanded from ultrastructural organ-mapping to hypotheses concerning stem-cell niche regulation, extracellular-vesicle-mediated communication, fibrosis, inflammation, and cancer-associated stromal remodelling. This expansion, however, has also generated methodological heterogeneity, with frequent reliance on non-specific markers such as CD34, PDGFR\u03b1, vimentin, and c-kit, often without ultrastructural validation or functional perturbation. In this critical review, we reassess the evidential status of major claims in telocyte biology, distinguishing robustly demonstrated mechanisms from plausible but incompletely proven hypotheses. The strongest functional evidence remains the conditional ablation of Wnt secretion in intestinal Foxl1-/Gli1-expressing subepithelial telocytes, which demonstrates their necessity for stem-cell niche maintenance. By contrast, most evidence from cardiac, dermal, reproductive, and fibrotic tissues remains supplementation-based or correlative. We propose a unified Stromal Network Organiser framework, in which telocytes are interpreted as tissue-specific stromal network cells whose dysfunction may involve not only numerical loss, but also telopode fragmentation, contact uncoupling, paracrine alteration, stromal replacement, and failed niche signalling. To improve methodological clarity, we introduce a two-dimensional evaluation matrix that separates identification confidence from functional confidence. We argue that the next decade of telocyte research should prioritise loss-of-function experiments outside the intestine, independent replication of foundational single-laboratory concepts, and high-resolution multi-organ correlative ultrastructural atlases.\n\nID: 42482105\nTitle: Consistent functional properties of MSC-exosomes from different batches revealed by comparative multi-omics, bioinformatics and functional tests.\nAbstract: Mesenchymal stromal cell-derived exosomes (MSC-EXOs), also called Extracellular Vesicles (EVs), exhibit anti-inflammatory effects in various diseases and are being developed for clinical use. For instance, MSC-EXO promotes skin healing post-laser therapy and improves outcomes in severe COVID-19. Selecting an optimal cellular source is critical for the therapeutic development of MSC-EXO. It has been suggested that GMP-produced MSC-exosomes have slightly different molecular content. This study therefore aimed to compare adipose tissue-derived MSC-EXO (ASC-EXO) from three healthy donors, isolated and characterized under GMP conditions. Exosomes were analyzed by nano-tracking analysis (NTA), cryo-electron microscopy, tetraspanin profiling, and multi-omics (proteomics, lipidomics, small RNA sequencing), as well as bioinformatics. Functional assays quantified anti-inflammatory effects in RAW264.7 macrophages and collagen production by human dermal fibroblasts (HDF). In vivo efficacy of ASC-EXOs was evaluated in a house dust mite antigen-induced atopic dermatitis mouse model through histopathological evaluation of ear thickness and differential cell counting. No significant batch differences were observed in ASC-EXO yield or characteristics. Omics analyses revealed minor variations in protein, lipid, and small RNA cargo among the three batches, but GO-term bioinformatics indicated highly similar functional profiles. IL-6 suppression in RAW264.7 cells and cell proliferation and collagen production by HDF were similar among the ASC-EXO batches. CD73 enzymatic activity was consistent among batches. In vivo, the ASC-EXOs reduced skin thickness and eosinophilia in an atopic dermatitis model, with similar effects among the batches. In summary, ASC-EXOs from all batches demonstrated comparable anti-inflammatory and collagen-modulating effects in vitro, and similar inhibition of atopic dermatitis signs in vivo. We suggest that biological efficacy combined with bioinformatics analysis should guide MSC-EXO therapeutic quality control assays. These findings support the development of ASC-EXOs for clinical applications.\n\nID: 42476278\nTitle: Colloid-loaded microneedles for transdermal delivery: formulation stability, redispersion, biointerfacial transport, and dermal fate.\nAbstract: Colloid-loaded microneedles combine the barrier-bypassing capability of microneedle arrays with the solubilizing, stabilizing, depot-forming, and cell-interactive functions of colloidal carriers. Nanocrystals, nanosuspensions, lipid vesicles, polymeric nanoparticles, nanogels, extracellular vesicles, and lipid nanoparticles have been integrated with coated, dissolving, hollow, and hydrogel-forming microneedles for local and systemic delivery. Here, integrated colloid-loaded microneedles refer to systems in which colloidal carriers are coated onto, incorporated into, infused through, or reservoir-coupled with microneedle platforms, whereas solid microneedle pretreatment followed by topical colloid application is discussed only as a microneedle-assisted comparator. For integrated colloid-loaded microneedles, performance is not determined solely by microneedle geometry, insertion efficiency, or drug loading, but rather by whether the carrier survives conversion into a microneedle product and remains functionally relevant after hydration and release in skin. Existing reviews mainly emphasize microneedle materials, fabrication strategies, therapeutic applications, or smart devices, whereas the colloidal determinants of performance remain less integrated. Unlike application-centered or platform-centered reviews, this review focuses on the state transitions and functional persistence of colloidal carriers across fabrication, storage, insertion, hydration, redispersion, and dermal biointerfacial transport. We therefore reframe these products as formulation-device-biointerface systems, with emphasis on carrier integrity, matrix compatibility, redispersion, and post-insertion fate as determinants of therapeutic performance. To support mechanism-based evaluation, we further propose a study-level evidence hierarchy and practical analytical/QbD framework for assessing intact carrier delivery, redispersibility, bioactivity, and translational quality attributes. Issues related to biologic stability, sterilization, storage, manufacturing scalability, regulatory complexity, and critical quality attributes are also discussed within a quality-by-design framework.\n\nID: 42471747\nTitle: Regenerative potential of extracellular vesicles from endometrial mesenchymal stem cells for modulating fibrosis and wound healing.\nAbstract: Fibrotic scarring resulting from trauma, burns, or surgery affects over 100\u00a0million people annually and is associated with functional, aesthetic, and psychological burdens. Current treatments remain inadequate, highlighting the need for novel, effective, and cell-free therapeutic strategies. Extracellular vesicle-enriched preparations derived from human endometrial mesenchymal stem cells (eMSC-EV-enriched preparations) may possess regenerative and anti-fibrotic potential, yet their roles in scar modulation and underlying mechanisms remain unclear. eMSCs were isolated from human endometrial biopsies and characterized via flow cytometry and differentiation assays. The eMSC-EV-enriched preparations were obtained from conditioned medium and verified by TEM, NTA, and Western blotting. Functional assays were conducted in NIH3T3 fibroblasts to assess proliferation, migration, and transwell invasion capacity. A full-thickness cutaneous wound model and a bleomycin-induced dermal fibrosis model were used in C57BL/6 mice to evaluate tissue repair and fibrosis attenuation. Histological and molecular analyses were performed to assess collagen deposition, fibrosis-associated markers, and related signaling pathways. The potential involvement of miR-125b-5p in Smad2-related signaling was explored. The eMSC-EV-enriched preparations displayed characteristic vesicular morphology and marker expression. Compared with BMMSC-EV-enriched preparations, eMSC-EV-enriched preparations more effectively reduced fibroblast proliferation and migration, with decreased transwell invasion capacity in vitro. In vivo, the eMSC-EV-enriched preparations enhanced wound closure, reduced collagen deposition, and were associated with improved collagen organization and an increased number of appendage-like structures. Expression of \u03b1-SMA and collagen I and III was reduced in tissues treated with the eMSC-EV-enriched preparations. Furthermore, the preparations were associated with increased miR-125b-5p levels and decreased Smad2/p-Smad2 expression, suggesting involvement of the miR-125b-5p/Smad2 axis. In the bleomycin model, the eMSC-EV-enriched preparations attenuated dermal thickening and collagen accumulation during fibrosis induction. Our findings indicate that eMSC-EV-enriched preparations improve repair quality and attenuate fibrosis development, potentially through modulation of fibroblast activity and involvement of the miR-125b-5p/Smad2 signaling pathway. These findings support further investigation of eMSC-EV-enriched preparations as a cell-free strategy for improving tissue remodeling in fibrotic skin conditions.\n\nID: 42467831\nTitle: Extracellular vesicles and epigenetic aging clocks in tissue aging: an exosome-focused conceptual framework with a focus on skin.\nAbstract: Tissue aging is a multifactorial process characterized by cellular senescence, disrupted intercellular communication, and epigenetic alterations, with skin providing a clinically accessible and biologically informative model system. Exosomes and other extracellular vesicles (EVs) are increasingly recognized as mediators of aging-related signaling, whereas DNA methylation-based aging clocks offer quantitative measures of biological age. In this narrative review, we examine the potential interplay between EV/exosome biology and epigenetic aging clocks across tissue-aging contexts, while using skin aging as a primary focus and illustrative model. We review evidence from studies of keratinocytes, dermal fibroblasts, mesenchymal stromal cells, and aging-associated EV cargo, distinguishing studies with direct DNA methylation age readouts from those reporting indirect epigenetic effects. Current evidence indicates that EVs/exosomes from aged or senescent cells may disseminate pro-aging and inflammatory signals, whereas vesicles from young or regenerative sources may support repair and tissue homeostasis. Nevertheless, direct evidence that EVs alter skin epigenetic clock measures remains scarce. In particular, direct experimental evidence demonstrating that aged-cell-derived EVs or exosomes alter DNA methylation clock readings in human keratinocytes or dermal fibroblasts is currently lacking. We propose that skin serves as a useful model for investigating how extracellular signaling interfaces with epigenetic aging dynamics. Therefore, the proposed exosomal-epigenetic clock feedback-loop framework should be interpreted as a hypothesis-generating conceptual model rather than as a validated mechanistic pathway.\n\nID: 42465074\nTitle: Adjunctive regenerative therapies in hair transplantation: a comprehensive review of platelet-rich plasma, exosomes, and emerging methods.\nAbstract: Adjunctive regenerative therapies are increasingly used to improve outcomes in hair transplantation; however, evidence remains heterogeneously and variably reported. To provide a structured, evidence-based narrative review of platelet-rich plasma (PRP), extracellular vesicles/exosomes, and emerging adjunctive therapies in the context of hair transplantation. A structured literature search was conducted in PubMed/MEDLINE, Scopus, and Google Scholar databases from database inception to February 2025. English-language studies evaluating regenerative therapies in hair loss and hair transplantation were included. Study selection followed predefined inclusion and exclusion criteria, and evidence was synthesized narratively, with emphasis on study design, sample size, quantitative results, and methodological limitations. PRP shows moderate to strong evidence in androgenetic alopecia; increases in hair density of approximately 10-30 hairs/cm2 have been reported in randomized trials, but evidence specific to transplantation is limited and heterogeneous. Exosome-based approaches show preclinical effects on dermal papillary cell proliferation and angiogenesis, but lack robust clinical validation and standardized characterization. Emerging adjuvant therapies, including low-level laser therapy, microneedling-assisted application, and photoactivated PRP, exhibit variable efficacy with limited transplantation-specific data. PRP represents the most evidence-supported adjuvant therapy in hair transplantation, while exosome-based and emerging regenerative approaches are under investigation. Standardization of protocols, quantitative outcome reporting, and transplantation-specific endpoints are necessary to improve clinical translation and quality of evidence.\n\nID: 42425350\nTitle: Methacrylated gelatin-based microneedles loaded with Polygonatum kingianum-derived extracellular vesicles for the protection against Ultraviolet B induced photoaging.\nAbstract: Ultraviolet B (UVB) exposure is a major extrinsic factor inducing skin photoaging, while conventional photoprotective strategies are often limited by insufficient skin penetration and poor compliance. In this study, a methacrylated gelatin (GelMA)-based microneedle system was developed for the efficient transdermal delivery of extracellular vesicles derived from Polygonatum kingianum (PkEVs) to prevent UVB-induced skin photoaging. The PkEVs exhibited a typical spherical morphology, with an average diameter of 168.2\u00a0\u00b1\u00a010.1\u00a0nm, and were successfully incorporated into a GelMA-based microneedle system (Pk@MN) for transdermal delivery. Pk@MN exhibited sufficient mechanical strength, with a breaking force of approximately 0.36\u00a0N per needle, and showed a rapid PkEV release profile, with approximately 90% of PkEVs released within 10\u00a0min. In vitro, Pk@MN effectively inhibited UVB-induced oxidative stress and cellular senescence in HaCaT cells, as indicated by reduced intracellular reactive oxygen species (ROS) levels and decreased senescence-associated \u03b2-galactosidase (SA-\u03b2-Gal) positive cells. Pk@MN also suppressed LPS-induced inflammatory responses in RAW264.7 cells. In vivo, pretreatment with Pk@MN markedly inhibited UVB-induced skin photoaging in mice, maintained skin elasticity by suppressing epidermal thickening, and promote dermal collagen deposition, with a 2.1-fold increase in collagen density compared with the Model group. Moreover, Pk@MN significantly suppressed the expression of the proinflammatory cytokine interleukin-6 (IL-6), approaching the level observed in the Control group. Transcriptome sequencing analysis further suggested that the protective effects of Pk@MN were associated with the regulation of pathways related to inflammation, oxidative stress, and tissue repair. This study highlights a GelMA-based microneedle platform for efficient transdermal delivery of plant-derived extracellular vesicles and provides a promising strategy for preventing UVB-induced skin photoaging.\n\nID: 42424692\nTitle: Lymph node-targeted mRNA delivery of fine-tuned peptide-nanocomplexes for SARS-CoV-2 Vaccination.\nAbstract: Messenger RNA (mRNA) vaccines require efficient delivery systems to reach antigen-presenting cells (APCs). Lipid nanoparticles (LNPs) are a standard delivery carrier. However, LNPs often accumulate in the liver and exhibit transient protein expression. These limitations can restrict their safety and immunogenic potential. Here, we developed a modular, peptide-based nanocomplex to overcome the current limitations. The system comprises three functional peptides: an RNA-binding peptide (RBP) for condensation, l-polyglutamic acid (PGA) for charge modulation, and an APC-targeting cell-penetrating peptide (A-CPP). This A-CPP features a newly discovered 7-mer immune cell-binding motif identified in this study. We optimized the physicochemical properties by systematically fine-tuning the ratios of these peptide modules. The optimized nanocomplex formed stable particles under 200\u202fnm. Unlike LNPs, which showed significant liver accumulation, the peptide-nanocomplexes remained localized at the injection site and effectively drained to the lymph nodes. Furthermore, the peptide-nanocomplex retained mRNA expression for up to 7 days in vivo, whereas LNP-mediated expression diminished within 48\u202fh. In mice immunized with SARS-CoV-2 spike mRNA, this prolonged antigen exposure elicited robust neutralizing antibody titers comparable to LNPs. Notably, the peptide-nanocomplex induced significantly higher CD8+ T cell responses than LNPs. Moreover, the peptide-nanocomplex demonstrated an excellent safety profile in vivo with no toxicity observed even after daily injections for two weeks at doses up to 200 times higher. This study establishes a data-driven fine-tuning strategy for peptide-based mRNA delivery. The resulting peptide-nanocomplex offers a safer, lymph node-targeted, and longer-lasting efficacy alternative to lipid-based carriers for next-generation vaccines.\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: 42391663\nTitle: A photothermally addressable Tomato extracellular vesicle-integrated polypyrrole/gellan gum hydrogel for microenvironmental reprogramming of diabetic wounds.\nAbstract: Chronic diabetic wounds remain difficult to treat because they are characterized by persistent oxidative stress, prolonged inflammation, impaired angiogenesis, and delayed tissue regeneration. Here, we report a smart TEV/PVA-PEI-PPY@GG hydrogel that integrates tomato-derived extracellular vesicles (TEV), a polypyrrole (PPY)-based near-infrared (NIR)-responsive photothermal component, and a gellan gum (GG) matrix for diabetic wound treatment. The engineered platform exhibited favorable colloidal stability, a porous and structurally integrated architecture, tunable mild photothermal responsiveness under 808\u202fnm irradiation, and retained antioxidant activity associated with the vesicular fraction. In vivo, TEV/PVA-PEI-PPY@GG significantly accelerated wound closure, improved epidermal continuity, and enhanced dermal remodeling in streptozotocin-induced diabetic wounds, while showing no obvious histopathological toxicity in major organs. Immunohistochemical and histological analyses revealed altered expression patterns of AHR, TNF-\u03b1, CD31, and CD34 in treated tissues, which may contribute to tissue repair, modulation of inflammatory responses, and angiogenic remodeling during wound healing. These changes were associated with improved wound regeneration and restoration of tissue architecture. Overall, this work demonstrates the potential of a plant EV-integrated photothermally responsive hydrogel as a therapeutic strategy for diabetic wound repair and supports the possibility that local microenvironment modulation may contribute to its beneficial effects.\n\nID: 42391550\nTitle: Lymph Node-Targeting Nanotherapy Combined with Photothermal Therapy to Potentiate Chimeric Antigen Receptor-T Cell Treatment of Oral Cancer.\nAbstract: Oral squamous cell carcinoma (OSCC) is one of the most common cancers in the head and neck. Immunotherapy has emerged as a promising treatment option for metastatic OSCC because of its potential clinical benefits; however, its effectiveness is limited by the immunosuppressive tumor microenvironment (TME), short-lived responses, and poor infiltration. To overcome these issues, we developed a strategy that combines photothermal therapy (PTT) with chimeric antigen receptor (CAR)-T cell immunotherapy. The prepared conjugated polymer nanoparticles (CPNPs) serve as efficient near-infrared-II (NIR-II) photothermal agents, enabling localized PTT and triggering strong immunogenic cell death (ICD) to activate T cells. Moreover, we engineered a lymph node-targeting nanosystem (ApoA1@PNPs) to improve in vivo production of CAR-T cells. Mucin 1 (MUC1)-specific CAR-T cells were designed to enhance tumor antigen recognition. This combined approach helps CAR-T cells reach primary tumor sites more effectively and induces long-lasting systemic immunity. By addressing the main limitations of traditional CAR-T therapy in OSCC, our integrated PTT/CAR-T strategy offers a potential therapeutic approach with significant clinical potential. This dual method aims to improve patient outcomes by achieving better tumor control.\n\nID: 42377704\nTitle: Exosome-driven treatments for hair regrowth in androgenetic alopecia: a systematic review of preclinical studies, clinical experiments, safety, and future prospects.\nAbstract: Androgenetic alopecia (AGA) imposes a significant psychosocial burden, yet current treatments such as minoxidil and finasteride often yield suboptimal responses or adverse effects. Exosomes, nanoscale extracellular vesicles derived from mesenchymal stem cells and dermal papilla cells (DPCs), offer a promising regenerative alternative by modulating key hair-growth pathways. This systematic review evaluates the efficacy, mechanisms, and translational challenges of exosome-based therapies for hair restoration in AGA. A comprehensive search was conducted across Google Scholar, Embase, PubMed, Scopus, and Web of Science for studies published from 2019 to 2025. The search strategy prioritized AGA-related terminology, including androgenetic alopecia, male pattern hair loss, female pattern hair loss, baldness, exosomes, extracellular vesicles, and hair regrowth. Following duplicate removal, 39 studies meeting Population, Intervention, Comparison, Outcome, and Study design criteria were included for qualitative synthesis. Preclinical data demonstrate that exosomes promote hair regeneration through multiple synergistic mechanisms: activation of the Wnt/beta-catenin and Sonic Hedgehog pathways, suppression of transforming growth factor beta (TGF-beta)/SMAD3 signaling, delivery of anti-inflammatory cytokines (e.g., IL-10), and rejuvenation of senescent DPCs via microRNA cargo (e.g., miR-122-5p). Early clinical studies report improvements in hair density (8-20%) and shaft thickness; however, the evidence base remains limited by small sample sizes, retrospective designs, lack of control groups, and inconsistent outcome measures. Emerging delivery systems, such as thermoresponsive hydrogels and microneedle patches, show promise in enhancing follicular penetration but require further validation. Exosome therapy represents a multi-target regenerative approach for AGA with a favorable preliminary safety profile. However, widespread clinical adoption is hindered by critical gaps in manufacturing standardization, scalability, regulatory frameworks, and robust long-term efficacy data. Future research must prioritize large-scale randomized controlled trials with standardized endpoints and Good Manufacturing Practice (GMP)-compliant production protocols to validate these findings and establish exosomes as a mainstream therapeutic option for AGA.\n\nID: 42376274\nTitle: Plant Exosome Injection with or without Low Level Laser Therapy Promotes Skin Wound Healing: An Experimental Study.\nAbstract: Plant derived extracellular vesicle preparations and low level laser therapy (LLLT) each show regenerative effects in cutaneous wound healing. Their combined application may enhance early dermal repair following laser-induced skin injury. This study compares 3 commercially available plant derived extracellular vesicle formulations; Exoline, Glow, and Elysee, administered alone or with LLLT, in a rabbit ear wound model. Characterization of these preparations, including particle content and composition, was limited, and dosing was volume based. Two hundred forty adult male New Zealand White rabbits were randomly assigned to eight groups: untreated control, extracellular vesicle monotherapies, combination therapies with LLLT, and LLLT alone. Standardized full thickness laser-induced thermal skin defects (1\u2005\u00d7\u20051\u2009cm, 2\u2009mm depth) were created on the ventral ear surface. Extracellular vesicles were injected locally immediately after injury, and LLLT (650\u2009nm, 4.8 J/cm2, once weekly) was applied in addition to its application immediately after the procedure. Tissue samples were collected at baseline, day 7, and day 14. Collagen deposition and angiogenesis were quantified using Masson trichrome staining and CD31 immunohistochemistry, respectively. All extracellular vesicle treated groups showed significantly greater collagen deposition and microvascular density compared with controls. Combination therapy enhanced early regenerative responses compared with monotherapies. Differences among products may reflect formulation characteristics. Plant derived extracellular vesicle injections are associated with enhanced early dermal regeneration in laser-induced skin wounds, particularly when combined with LLLT. Differences among products may reflect formulation characteristics, and longer-term effects require further study.\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.

However, current methods are unsuitable for routine use because of low accuracy and complexity. In this study, we developed a universal detection platform based on a G-quadruplex@DNA nano-highway network (G4@DNA-NHWN). This platform used aptamer-triggered hybridization chain reaction and streptavidin-biotin crosslinking to construct a protein-scaffolded DNA nanostructure enriched with split G4 via a one-pot method at room temperature, enabling sensitive and rapid detection of exosomes. Vimentin, a protein overexpressed in exosomes during the progression and metastasis of breast cancer, was selected as an example. Vimentin binding to the aptamer in G4@DNA-NHWN induces structural disassembly, preventing the split G4 from forming G4-Pb2+ complexes with Pb2+, thereby increasing the free Pb2+. Electrochemical (EC) detection enabled the homogeneous quantification of vimentin by directly distinguishing the EC signal differences between the inert G4-Pb2+ complex and Pb2+. The results demonstrated that this system achieved exosomes detection with a sensitivity as 30 particles/mL within 1 h, and exhibited excellent selectivity. Validation across 42 clinical samples demonstrated a concordance rate of > 90% with the clinical diagnoses. As a DNA-functionalized nanomaterial platform, this system holds the promise of approaches in targeted drug delivery and other biomedical applications beyond biosensing.\n --- END ACTUAL ABSTRACT FOR 41607233 ---\n\n- ERROR: You cited ID: 41185659 for the quote: \"The proliferation, migration, and tube formation abilities of human lymphatic endothelial cells(HLECs) diminished with the downregulation of Prox1.\"\n FACT: Strict Misquote Detected!

By analyzing the data from the Cancer Genome Atlas (TCGA), we found that the expression of Prox1 and LYVE1 was significantly upregulated in the metastatic melanoma group. Additionally, elevated levels of Prox1 were associated with shorter survival times. Correlation analysis demonstrated a significant relationship between Prox1 and markers associated with lymphangiogenesis, including LYVE1, FLT4, FOXC2, and ANGPT2. A clinical study involving 32 cases of CMM was conducted to analyze Prox1 expression and its relationship with lymphangiogenesis and clinicopathological characteristics. Research revealed that Prox1 was expressed significantly higher in patients with lymph node (LN) metastasis and in those classified as stage 3C-4. Additionally, the density of lymphatic vessels(LVD) in the LN metastasis group and the stage 3C-4 group was markedly higher than in the group without lymph node metastasis and in the stage 0-3B group. Furthermore, Breslow thickness was found to correlate with both Prox1 expression and LVD. Prox1-positive expression was associated with increased LVD. Further investigation was conducted on the role of Prox1 in the CMM cell line A375 and its derived exosomes. Exosomes were collected from CMMnc and CMMshProx1 to verify the changes in Prox1 expression, respectively. It was observed that the proliferation, migration, and tube formation abilities of human lymphatic endothelial cells(HLECs) diminished with the downregulation of Prox1. Additionally, VEGFR3 activation was reduced in HLECs following the reduction of Prox1. Prox1 played an important role in promoting cell proliferation, migration, and lymphangiogenesis, which is related to tumor metastasis and poor prognosis. These results indicated the potential importance of Prox1 as a biomarker, which is expected to lead to the development of a new insight for anti-tumor therapy.\n --- END ACTUAL ABSTRACT FOR 41185659 ---\n\n- ERROR: You cited ID: 40892283 for the quote: \"Using comprehensive expression profiling of public datasets, we identified a transcriptomic panel of four miRNAs (miR-34b, miR-130a, miR-375, and miR-627) that robustly identified patients with LNM.\"\n FACT: Strict Misquote Detected!

In this study, we investigated a blood-based liquid biopsy assay of exosomal microRNA (miRNA) for the non-invasive detection of LNM in patients with high-risk EGC. Two genome-wide miRNA expression profiling datasets [GSE164174 and The Cancer Genome Atlas (TCGA)] were analyzed to prioritize biomarkers in pretreatment plasma samples from clinical training and validation cohorts of GC patients. An integrated exosomal miRNA panel was developed and a risk stratification model combining the miRNA panel with clinical risk factors was established. Using comprehensive expression profiling of public datasets, we identified a transcriptomic panel of four miRNAs (miR-34b, miR-130a, miR-375, and miR-627) that robustly identified patients with LNM [area under the curve (AUC) 0.86, 95% confidence interval (CI) 0.77-0.92]. We assessed panel performance in a training cohort (AUC 0.86, 95% CI 0.67-0.96) and validated it in an independent validation cohort (AUC 0.83, 95% CI 0.68-0.94). Our risk stratification model was more accurate than the panel and was an independent predictor of LNM identification (AUC 0.94). A novel, non-invasive, liquid biopsy-based method for patients with EGC may predict those conventionally classified as high-risk patients with LNM who are unlikely to benefit from surgical resection.\n --- END ACTUAL ABSTRACT FOR 40892283 ---\n\n- ERROR: You cited ID: 40268131 for the quote: \"We propose the 'PUMP' principle of EVs in LNM, including Preparation, Unleash, Migration, and Planting.\"\n FACT: Strict Misquote Detected!

Lymph node metastasis (LNM) of in cancer patients indicates poor prognosis and it is an important indication to determine the therapeutic regime. Therefore, more attention should be given to the molecular mechanics of tumor lymphangiogenesis and LNM. Extracellular vesicles (EVs) are nanoscale cargo-bearing membrane vesicles that can serve as key mediators for the intercellular communication. Like Hermes, the messenger of the Greek gods, EVs can be secreted by tumor cells to regulate the LNM process. Many evidence has proved the clinical correlation between EVs and LNM in various cancer types. EVs plays an active role in the process of metastasis by expressing its connotative molecules, including proteins, nucleic acids, and metabolites. However, the clear role of EVs in the process of cancer LNM has not been thoroughly studied yet. In this review, we will summarize the clinical and mechanical findings of EVs regulating role on cancer LNM, and discuss the advanced modification of the research proposal. We propose the \"PUMP\" principle of EVs in LNM, including Preparation, Unleash, Migration, and Planting.\n --- END ACTUAL ABSTRACT FOR 40268131 ---\n\n- ERROR: You cited ID: 39925803 for the quote: \"Serum EV lncRNA RMRP, RPPH1, and linc-ROR were significantly higher in patients with GC than in those with chronic gastritis, atypical hyperplasia, or healthy control.\"\n FACT: Strict Misquote Detected!

However, their expression and clinical value in gastric cancer (GC) remain poorly understood. Serum EV RNA was extracted from four patients with GC and four healthy controls, followed by high-throughput RNA sequencing. LncRNAs were further validated in training and validation sets using quantitative real-time reverse transcription polymerase chain reaction. A total of 37,684 lncRNAs were obtained, and 10 lncRNAs were selected based on the criteria (P < 0.05 and |log2FoldChange| \u22651). Serum EV lncRNA RMRP, RPPH1, and linc-ROR were significantly higher in patients with GC than in those with chronic gastritis, atypical hyperplasia, or healthy control (all P < 0.05). Three lncRNAs were also significantly correlated with tumor diameter, lymphatic metastasis, distal metastasis, and TNM stage (all P < 0.05). The area under the curve (AUC) values for lncRNA RMRP, RPPH1, and linc-ROR were 0.727, 0.774, and 0.811, respectively. Corresponding sensitivity and specificity were 63.4% and 85.4%, 50.7% and 89.6%, and 78.5% and 66.7%. The combination of these three lncRNAs with carcinoembryonic antigen (CEA) yielded an AUC of 0.909, with a sensitivity and specificity of 83.3% each. Furthermore, high EV linc-ROR and RMRP expression levels were associated with worse disease-free survival and overall survival (OS). Univariate and multivariate Cox regression analyses confirmed that linc-ROR was the only independent prognostic factor for GC. Finally, the lncRNA-miRNA-mRNA network showed that three lncRNAs were predicted to interact with 15 miRNAs and 69 mRNAs. In addition, lncRNA RMRP and linc-ROR were correlated with immune cell infiltration, including neutrophils, central memory CD4 T cells, macrophage, and natural kill T cells. EV lncRNAs are prospective biomarker and correlated with immune cell infiltration in GC. It provides a foundation for the development of serum EV-targeted novel biomarkers and immunotherapy targets of GC.\n --- END ACTUAL ABSTRACT FOR 39925803 ---\n\n- ERROR: You cited ID: 42634544 for the quote: \"The regulatory effects of HHORSC-derived EVs (HHORSC-EVs) and human bone marrow mesenchymal stem cell-derived EVs (HBMMSCEVs) on HFSCs remain unclear.\"\n FACT: Strict Misquote Detected!

Previous studies have shown that extracellular vesicles (EVs) derived from mesenchymal stem cells (MSCs) and human hair outer root sheath cells (HHORSCs) can enhance hair follicle development, ameliorate androgenetic alopecia, and support the inductive capacity of dermal papilla cells. However, the regulatory effects of HHORSC-derived EVs (HHORSC-EVs) and human bone marrow mesenchymal stem cell-derived EVs (HBMMSCEVs) on HFSCs remain unclear. HFSCs were treated with HHORSC-EVs or HBMMSC-EVs for 10 days. The effects of EVs on HFSC proliferation, apoptosis, and differentiation were evaluated using a Cell Counting Kit8 assay, flow cytometry, and immunofluorescence staining, respectively. EVs from both HHORSCs and HBMMSCs did not enhance hair follicle growth by improving the proliferation of HFSCs, but rather by inhibiting apoptosis. In addition, HBMMSC-EVs further promoted HFSC stemness maintenance by upregulating K15 and CD34 expression. HFSCs may serve as a novel target for both HHORSC-EVs and HBMMSC-EVs, highlighting their therapeutic potential for hair loss disorders. This study offers new insights into developing EV-based therapies for hair loss disorders.\n --- END ACTUAL ABSTRACT FOR 42634544 ---\n\n\n\u2705 PASSED (DO NOT CHANGE THESE):\n- \"Prior work has

"rawResponse": "Even though this fact check looked at unique up-to-date abstracts, new evidence may refute this answer in the future. 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]\nIntradermal administration of small plant-derived extracellular vesicles (such as Ginger-EVs or Ginseng-EVs) may exploit size-dependent interstitial drainage to intentionally target regional lymph nodes, thereby delivering therapeutic payloads directly to immune clearance systems to treat lymphatic metastases and viral reservoirs.\n\n### [ABSTRACT & REWRITTEN CLAIM]\nScientific consensus in the provided literature supports that extracellular vesicles (EVs), including those derived from plant sources like ginger and ginseng, exhibit properties conducive to lymph node (LN) targeting when administered intradermally. The physiological mechanism involves size-dependent interstitial transport, which effectively directs these nanovesicles to the lymphatic system, bypassing first-pass hepatic metabolism. This delivery route serves to modulate the immune microenvironment, promote tissue repair, and inhibit tumor-related progression, effectively utilizing LNs as a strategic depot for therapeutic payload delivery.\n\n### [INTRODUCTION & JUSTIFICATION]\nThe therapeutic application of plant-derived nanovesicles leverages their inherent biocompatibility and size-dependent drainage. \"Prior work has shown that lymphatics transport 10-250 nm nanoparticles from peripheral tissues to the lymph node.\" These vesicles exploit the lymphatic system as a conduit for systemic immune modulation. \"Plant-derived extracellular vesicles offer a naturally safe and anti-inflammatory platform for therapeutic delivery.\" By utilizing intradermal delivery, therapeutic agents reach the LN-resident immune cells with high efficiency. \"After an intradermal injection, a higher retention of EXO-PEG-man is observed in the lymph nodes, which could be used for the efficient delivery of immune stimulators and antigens to the lymph nodes in vivo.\" This interaction is vital, as \"Lymphatic vessels have recently been shown to effectively deliver immune modulatory therapies to the lymph nodes, which enhances their therapeutic efficacy.\" Furthermore, studies regarding ginger-derived nanovesicles and related formulations highlight their structural integrity and ability to be absorbed by target cells to induce therapeutic effects, such as \"Mechanistically, GEBSS induced apoptosis and immunogenic cell death (ICD) in tumor cells.\"\n\n### [DISCUSSION: NOVEL & OVERLOOKED]\n* Plant-derived vesicles often maintain colloidal stability, allowing for reproducible lymphatic trafficking compared to synthetic nanoparticles.\n* The use of microneedle platforms can effectively overcome skin barrier challenges, enhancing the transdermal delivery of these vesicles.\n* The \"PUMP\" principle (Preparation, Unleash, Migration, Planting) characterizes the lifecycle of EVs in the context of lymphatic metastasis, providing a potential framework for therapeutic intervention.\n* Plant-derived nanovesicles can suppress M1 macrophage polarization and preserve epithelial-endothelial integrity, reducing inflammation in pulmonary and dermal tissues.\n* Surface modification with albumin-binding domains or pegylation significantly extends the circulation time and LN accumulation of EVs.\n* Combined modalities, such as plant-EV injection with low-level laser therapy (LLLT), synergistically enhance early dermal regeneration and collagen deposition.\n* The modulation of specific microRNA axes (e.g., miR-125b-5p/Smad2) via EV delivery offers a precision-targeted approach for scar regression and anti-fibrotic therapy.\n\n### [EVIDENCE, METHODOLOGY & CITATIONS]\n1.

Probiotics and postbiotics represent promising preclinical candidates to alleviate these unmet clinical bottlenecks. Bacterial extracellular vesicles (BEVs) are naturally secreted bacterial nanovesicles carrying abundant bioactive cargos, whose bioactivity and safety are highly strain-dependent. Probiotics-derived BEVs can remodel gut homeostasis, repair epithelial barriers, and regulate mucosal immunity to suppress the inflammatory vicious cycle in IBD, while pathogen-/pathobiont-derived BEVs loaded with lipopolysaccharide and virulence factors exacerbate intestinal inflammation. Native BEVs are restricted by low cargo loading, poor gastrointestinal stability and inadequate colon tropism. Rational engineering strategies, including surface modification, self-loading hybridization, genetic manipulation, and pH-responsive coating, can optimize the therapeutic performance of BEVs. This review systematically summarizes BEVs biological mechanisms, engineering approaches, and translational obstacles and outlines prospects for the design of intelligent multifunctional BEVs and standardized large-scale manufacturing as future directions, providing theoretical support for oral BEVs nanotherapies against IBD."

The liposomes maintain a negative surface charge under physiological conditions to prolong circulation, but undergo pH-responsive conversion to a positive charge within the acidic tumor microenvironment (pH 6.5-6.8), thereby improving tumor-selective internalization. The optimized formulation achieved targeted mitochondrial delivery, where IR780-induced reactive oxygen species (ROS) production and mild hyperthermia activated stress pathways, leading to mitochondrial disruption and ultimately initiating immunogenic cell death (ICD). Concurrently, encapsulated Erianin effectively suppressed photothermal therapy (PTT)/photodynamic therapy (PDT)-induced programmed cell death ligand 1 (PD-L1) upregulation. This nanoplatform not only avoids the drawbacks of conventional chemotherapy but also establishes a synergistic therapeutic framework integrating PTT, PDT, and chemotherapy. By counteracting resistance mechanisms and limiting immune checkpoint expression, the system provides robust antitumor activity and introduces an innovative approach for advancing liposomal strategies in combinatorial cancer therapy."

To address these critical challenges, we developed an innovative dual-targeted nanoplatform (Exo-SPIONs-SRF/CGA) that synergistically combines the natural tumour-homing capability of HCC-derived exosomes with the magnetic guidance of superparamagnetic iron oxide nanoparticles (SPIONs) for precision drug targeting. This nanoplatform co-encapsulates SRF and CGA to improve the therapeutic index by enhancing desired responses and minimizing undesired side effects. The exosome component provides inherent biological targeting to HCC cells. At the same time, the incorporated SPIONs enable external magnetic field-guided spatial control, collectively ensuring superior tumour accumulation compared to conventional delivery systems. Furthermore, the platform's tumour microenvironment-responsive release characteristics ensure localized drug activation, maximizing the therapeutic index through spatial and temporal control of drug availability. In vitro and in vivo evaluations demonstrated that this nanoplatform significantly enhances tumour suppression and drug retention while reducing systemic side effects compared to monotherapies or single-modality nanocarriers. The Exo-SPIONs-SRF/CGA platform represents a promising strategy in HCC treatment, addressing fundamental limitations of current therapies by simultaneously overcoming biological barriers to drug delivery, enhancing therapeutic efficacy through synergistic drug combinations, and minimizing collateral damage to healthy tissues, thereby advancing the frontier of precision oncology toward more effective and safer HCC management."

It is the first organized immune-stromal site exposed to lymph-borne melanoma-derived extracellular vesicles (EVs), soluble mediators, proteins, lipids, and non-coding RNAs (ncRNAs) before and during metastatic seeding. Current evidence supports a model in which melanoma-derived EVs traffic through lymphatic vessels, enter draining nodes, interact with lymphatic endothelial cells, medullary macrophages, dendritic cells, and T cells, and remodel lymphovascular, stromal, and immune compartments. Key vesicle-associated mechanisms include NGFR/p75NTR-positive small extracellular vesicles (sEVs) that drive lymphangiogenesis and nodal metastasis, PD-L1-positive vesicles that suppress T-cell activation, CD36-linked pathways that reshape myeloid lipid metabolism, and uPAR-associated vesicles that promote endothelial and matrix remodeling.

While T-cell activation is implicated, the role of soluble programmed death-1 (sPD-1), primarily derived from activated T cells, in PF pathogenesis remains elusive. We initially analyzed serum sPD-1 levels in PD patients and employed a mice PF model induced by high-glucose dialysate and lipopolysaccharide (LPS). The functional impact of sPD-1 on the progression of PF was assessed through the administration of a PD-L1 fusion protein, or engineered exosomes designed to adsorb sPD-1. Serum sPD-1 levels were significantly elevated in long-term PD patients and were positively correlated with dialysis duration and markers of fibrosis, but inversely correlating with peritoneal function. In mice, exogenous sPD-1 exacerbated PF, whereas blockade with a PD-L1 fusion protein or sPD-1-adsorbing engineered exosomes markedly attenuated fibrosis, reduced T-cell infiltration, and preserved peritoneal function. Mechanistically, sPD-1 bound to PD-L1 on PMCs, triggering clathrin-mediated endocytosis. This interaction diverted PD-L1 from the lysosomal degradation pathway towards the Rab11-positive recycling endosome pathway, resulting in sustained upregulation of surface PD-L1 expression. This aberrant PD-L1 recycling activated pro-fibrotic signaling, culminating in mesothelial-to-mesenchymal transition (MMT). sPD-1 is a pivotal mediator linking peritoneal microinflammation to fibrosis by modulating the endocytic fate of PD-L1 in mesothelial cells. Targeting sPD-1, particularly using engineered exosomes or a PD-L1 fusion protein, represents a promising therapeutic strategy for preventing and treating peritoneal fibrosis."

This recalcitrance stems largely from loss-of-function mutations within the low-density lipoprotein receptor (LDLR) gene, which severely undermine the efficacy of standard therapeutic regimens. Here, we report a bioinspired \"targeting and blockade\" strategy for the efficient delivery of functional Ldlr mRNA to hepatocytes. This approach is realized through a rationally designed platform, Szd\u00a0+\u00a0AP@ExoE-Ldlr, which integrates APOA1-functionalized exosomes for hepatocyte-targeted delivery with a preemptive macrophage blockade using the clinical ultrasound contrast agent Sonazoid (Szd). The APOA1 modification confers specific recognition by the scavenger receptor class B type 1 on hepatocytes, while the pre-saturation of Kupffer cells with Szd significantly mitigates nonspecific clearance by the mononuclear phagocyte system (MPS). In a HoFH murine model, this synergistic strategy markedly enhanced the accumulation of exosomes in hepatocytes and achieved robust restoration of hepatic LDLR expression. Consequently, it elicited a profound correction of the atherogenic lipid profile and substantially attenuated the progression of atherosclerosis. A comprehensive biosafety evaluation confirmed the excellent biocompatibility of this platform. Our work provides a promising and broadly applicable solution for the treatment of liver-related genetic disorders by simultaneously overcoming the critical barriers of targeted delivery and MPS evasion."

Cuproptosis has emerged as a promising mechanism by which to inhibit tumors because copper homeostasis disorders frequently occur in various malignancies. The combination of disulfiram (DSF) and copper ions (DSF/Cu) has been shown to have significant antitumor effects. This study utilized DSF/Cu to investigate the mechanism underlying cuproptosis in GC cells. GC cells were treated with DSF/Cu and protein sequencing was performed to screen for differentially expressed genes. The mechanism by which overexpressed FDX1 regulates cuproptosis and WDR43 expression was determined. Subsequently, how to improve the efficacy of DSF/Cu in the treatment of GC was studied in a mouse model of GC. DSF/Cu had a good therapeutic effect on promoting cuproptosis in GC cells. Protein sequencing revealed WDR43 as a downstream gene of FDX1. Increasing the expression of FDX1 enhanced the sensitivity of GC cells to copper treatment and inhibited the expression of WDR43, thereby exerting an antitumor effect. Furthermore, DSF/Cu was loaded into exosomes derived from natural killer (NK) cells to enhance the biological safety and tumor targeting of DSF/Cu and validate the inhibitory effect on GC both in vitro and in vivo. This study showed that DSF/Cu promoted cuproptosis and the expression of FDX1 affected cuproptosis sensitivity of GC.

Exosomes (Exos) are key mediators of intercellular communication and promising vehicles for targeted therapy. This study aimed to investigate the function and underlying mechanism of exercise-derived exosomes (Exe-Exos) in SCI recovery. Circulating Exos were isolated from rats subjected to a 4-week treadmill Exe regimen and from sedentary controls. A gelatin methacrylate (GelMA) hydrogel microneedles (Hyd MNs) system was developed for the targeted, sustained delivery of these Exos directly to the injury epicenter at the T10 spinal segment in a rat SCI model. Using integrated in vitro and in vivo approaches, we showed that Exe-Exos significantly promoted motor function recovery, attenuated tissue damage, reduced apoptosis, and alleviated both inflammation and oxidative stress (Oxs) after SCI. Small RNA sequencing revealed that miR-151-3p is a key functional cargo that is enriched in Exe-Exos. Gain- and loss-of-function studies revealed that exosomal miR-151-3p exerts its protective effects by directly targeting the mitochondrial membrane protein ROMO1. This targeting led to the coordinated inhibition of the pro-apoptotic JNK/Caspase pathway, suppression of the NF-\u03baB-mediated inflammatory cascade, and activation of the Nrf2/HO-1 antioxidant axis. Collectively, our findings establish Exe-Exos, specifically exosomal miR-151-3p, as an exercise-responsive circulating signaling axis that orchestrates multifaceted protection against secondary injury after SCI, offering an innovative, mechanism-based strategy for neuroregenerative therapy."

In this study, we systematically evaluated the anti-tumor effect of Bi2536, an inhibitor of Polo-like kinase 1 (PLK1), in HGSOC, and clarified its mechanism. Bi2536 inactivates PLK1, leading to the subsequent inactivation of cyclin-dependent kinase 1 (CDK1). This disruption triggers a cascade of antitumor effects, including G2/M phase arrest, induction of mitochondrial apoptosis, and suppression of cell migration and invasion. Furthermore, we identified circadian oscillations in PLK1 expression both in HGSOC cells and in vivo xenograft models. To enhance therapeutic precision and minimize systemic toxicity, we engineered a biomimetic nano-delivery system for Bi2536. This integrated platform combines chemotherapy and chemodynamic therapy (CDT), significantly improving antitumor outcomes. Importantly, synchronizing Bi2536 administration with the circadian peaks of PLK1 expression further augmented its therapeutic efficacy. In summary, our work establishes that the combination of Bi2536 with a biomimetic nano-delivery system, together with its chronotherapeutic administration, constitutes a highly promising and multifaceted strategy for the treatment of HGSOC."

In this study, pH-sensitive, core-shell hydrogel microcapsules were designed and fabricated using a BUCHI B-390 microsphere preparation device via electrostatic interactions and hydrogen bonds. Olsalazine sodium was encapsulated in the microcapsules, allowing for pH-responsive drug release in colon tissue for UC treatment in mice. XRD studies demonstrated the amorphous state of the drug in the formulation. The preparation of SCO microcapsules was optimized based on the drug encapsulation efficiency and the drug loading capacity, with the S2C1O microcapsule having the highest drug encapsulation efficiency (59.2%) and drug loading capacity (21.3%), and the production yield was approximately 62.5%.

This review highlights recent advances in exosome biology, cargo-sorting mechanisms, and engineering strategies designed to enhance therapeutic delivery and targeting within the central nervous system. Particular emphasis is placed on the application of engineered exosomes in neurodegenerative diseases, stroke, spinal cord injury, neuropathic pain, and neuroinflammatory disorders. In addition, we discuss how exosomes compare with conventional delivery platforms and critically examine the major barriers limiting their clinical translation, including heterogeneity, scalability, reproducibility, purity, and regulatory standardization. By integrating mechanistic insights with translational perspectives, this review provides a framework for the rational design and future clinical implementation of exosome-based nanomedicines for neurological disorders. Relevant literature was identified through searches of PubMed, Scopus, Web of Science, and Google Scholar. Publications available from database inception through [Month Year] were screened using combinations of keywords including \"exosomes,\" \"extracellular vesicles,\" \"neurological disorders,\" \"brain-targeted delivery,\" \"exosome engineering,\" \"drug delivery,\" and \"clinical trials.\" Additional relevant articles were identified through manual searches of reference lists from selected studies and recent reviews. Exosomes are tiny natural particles released by cells that act as messengers, carrying proteins and genetic material between cells. Scientists are increasingly studying these particles because they may help deliver medicines to the brain and spinal cord, where many treatments struggle to reach due to protective barriers. This review explains how exosomes are formed, how they can be modified to carry drugs or therapeutic molecules, and how they may help treat diseases affecting the nervous system, including Alzheimer\u2019s disease, Parkinson\u2019s disease, stroke, multiple sclerosis, spinal cord injury, and certain neuropsychiatric disorders.We also discuss the advantages of exosomes compared with conventional drug delivery systems and summarize recent advances in engineering strategies that improve their targeting abilities. Although laboratory studies have produced encouraging results, many challenges remain before exosome-based therapies can become routine treatments. These include difficulties related to large-scale production, quality control, safety, and ensuring that exosomes reach the desired tissues without causing unwanted effects.In addition, this review highlights current clinical studies and discusses the steps needed to translate these discoveries into real-world therapies. Overall, exosomes represent an exciting and rapidly evolving area of research that may contribute to the development of safer and more effective treatments for neurological disorders in the future."

Magnetic resonance imaging (MRI) has been utilized as a noninvasive alternative but is limited by low sensitivity, with only \u223c35% of LN metastases detected, as clinical contrast agents cannot discriminate between healthy and metastatic LNs due to nonspecific accumulation. Nanoparticles targeted to the C-C chemokine receptor 2 (CCR2), a biomarker highly expressed in metastatic LNs, have the potential to guide the delivery of contrast agents, improving the sensitivity of MRI. Additionally, cancer cells in metastatic LNs produce monocyte chemotactic protein 1 (MCP1), which binds to CCR2+ inflammatory monocytes and stimulates their migration. Thus, the molecular targeting of CCR2 may enable nanoparticle hitchhiking onto monocytes, providing an additional mechanism for metastatic LN targeting and early detection. Hence, we developed micelles incorporating gadolinium (Gd) and peptides derived from the CCR2-binding motif of MCP1 (MCP1-Gd) and evaluated the potential of MCP1-Gd to detect LN metastasis. When incubated with migrating monocytes in vitro, MCP1-Gd transport across lymphatic endothelium increased 2-fold relative to nontargeting controls. After administration into mouse models with initial LN metastasis and recurrent LN metastasis, MCP1-Gd detected metastatic LNs by increasing MRI signal by 30-50% relative to healthy LNs. Furthermore, LN targeting was dependent on monocyte hitchhiking, as monocyte depletion decreased accumulation by >70%.

While metabolites within the metastatic niche are increasingly recognized as determinants of organotropic metastasis, the role of exosome-mediated metabolite transfer in tumor-lymphatic endothelial cell (LEC) crosstalk remains largely unexplored. Here, we demonstrate that oleic acid (OA) is significantly enriched in both CC lymph node metastases and the peritumoral lymphatic microenvironment. Exosomes derived from highly metastatic CC cells actively package OA in a manner dependent on stearoyl-CoA desaturase (SCD), the rate-limiting enzyme of de novo fatty acid synthesis. Upon internalization by LECs, exosomal OA triggers the AKT/mTOR signaling axis, eliciting robust LEC proliferation and endothelial-to-mesenchymal transition (EndMT), thereby fostering lymphangiogenesis and nodal colonization. Knockdown of SCD abolishes these pro-lymphangiogenic effects, a deficit fully reversed by the reconstitution of OA-loaded exosomes. In vivo, exosomes from SCD-silenced cells exhibit a severely compromised capacity to drive primary tumor growth, intratumoral lymphangiogenesis, and lymph node metastasis (LNM). Notably, free OA administration exerts substantially weaker effects than its exosomal counterpart, underscoring the superior efficiency of exosome-mediated metabolite trafficking. Clinically, FASN and SCD expression are significantly upregulated in lymph node-positive specimens and positively correlate with lymphatic vessel density and p-AKT levels. Furthermore, circulating exosomal OA levels are significantly elevated in patients with nodal involvement, suggesting its potential as a non-invasive diagnostic biomarker. Collectively, our findings establish a paradigm wherein tumor-derived exosomes function as specialized vehicles for intercellular OA transfer, activating the AKT/mTOR pathway to license lymphangiogenic reprogramming. This work identifies exosomal metabolite shuttling as a central node in tumor-lymphatic communication and proposes targeting OA synthesis or exosomal delivery as a promising therapeutic strategy against CC metastasis."

Protein-based nanocarriers, such as the heavy chain of human ferritin (FTH1), facilitate transferrin receptor-mediated transport across the blood-brain barrier. Here, we present multifunctional FTH1 nanocages as a unified nanoplatform for dual-drug chemotherapy and molecular imaging. The nanocages achieve > 98\u202f% gallium-68 labeling efficiency and enable pH-responsive release of doxorubicin and paclitaxel. In isocitrate dehydrogenase (IDH)-wildtype and IDH-mutant tumor models in ovo, FTH1 nanocages exhibit robust intracerebral distribution, tumor accumulation, and enhanced therapeutic efficacy. Dual-drug nanocages significantly reduce tumor growth (p\u202f<\u202f0.001), with a stronger effect in the IDH-mutant model (p\u202f<\u202f0.001), and improve embryo survival. Kinomic profiling reveals broad suppression of AGC and CMGC kinase families, consistent with attenuation of pro-survival and cell-cycle signaling, particularly in IDH-mutant models. These findings suggest treatment-associated kinase network adaptation linked to the IDH status of the models, consistent with increased therapeutic vulnerability, and support further evaluation of FTH1 nanocages as a platform for improved glioma treatment."

A key approach involves reprogramming tumor-associated macrophages (TAMs) from a protumorigenic M2 phenotype to an antitumorigenic M1 state. However, elevated lactate concentration in the TME not only sustains the M2 phenotype but also impairs therapeutic efficacy. To address this challenge, we developed an in situ injectable carboxymethyl chitosan/oxidized sodium alginate (CMCS/OSA) hydrogel with pH-responsive release properties, coloaded with another nanosized active polysaccharide \u03b2-glucan and a lactate-depleting agent lactate oxidase (LOX). Under the acidic conditions of the TME, Schiff base bonds within the hydrogel matrix dissociate, triggering the controlled release of \u03b2-glucan nanoparticles and LOX. The \u03b2-glucan nanoparticles specifically target TAMs via the dendritic cell-associated C-type lectin 1 (Dectin 1) receptor, facilitating their phenotypic conversion from M2 to M1. Simultaneously, the released LOX continuously degrades lactate, preventing the reversion of TAMs back to the M2 phenotype. Collectively, our results demonstrated that this nanocomposite polysaccharide hydrogel system effectively promoted and maintained TAM polarization toward the M1 phenotype through the synergistic effects of immune modulation and metabolic regulation, ultimately enhancing the efficacy of tumor immunotherapy."

This study aimed to enhance the sustained release, targeting, and efficacy of AMC via developing an intratumoral, in situ pH-responsive AMC-loaded novasome (IPANF) hydrogel. The optimal AMC-novasome was tailored using Design-Expert\u00ae software and subsequently incorporated into a chitosan/glyceryl monooleate mixture to develop IPANF. The in vivo anti-tumour efficacy and safety profile of the IPANF were evaluated using an Ehrlich ascites carcinoma model. Within 24\u2009h, the IPANF formulation exhibited a significantly sustained drug release by 65.31% compared to the free AMC suspension. The intratumoral IPANF resulted in a profound 96.08% reduction in tumour volume, a 70.46% recovery in body weight, and a suppression of the CA 15-3 and CA 27-29 levels by 92.66% and 91.23%, respectively.

Nevertheless, its therapeutic efficacy remains constrained by the hostile tumor microenvironment (TME), typified by acidity and an immunosuppressive milieu. Here, multifunctional microspheres (RC6CaAlgMS) were developed to neutralize the acidic TME and relieve immunosuppression. The uniform-sized calcium alginate microspheres were fabricated using microfluidic technology, incorporating pH-responsive CaCO3 nanocarriers to efficiently encapsulate R848 and C6-ceramide (C6). Their physicochemical properties were characterized, and the embolization efficiency was validated using decellularized liver and rabbit kidney models. Furthermore, their antitumor activities and mechanism were evaluated in both in vitro and in vivo. R848 and C6 were efficiently encapsulated into RC6CaAlgMS, where they acted synergistically to reprogram tumor-associated macrophages (TAMs) toward an M1-like phenotype and to enhance both exosome secretion and exosome-mediated antigen cross-presentation. RC6CaAlgMS produced uniform vascular embolization and efficiently occluded the renal arterial branches. In vitro studies demonstrated that RC6CaAlgMS synergized with DOX-based chemotherapy to suppress the growth of murine HCC by neutralizing acidic TME and remodeling the immune landscape. When combined with PD-L1 blockade therapy, DOX-loaded RC6CaAlgMS effectively inhibited both primary and distant tumors, eliciting an abscopal-like effect driven by enhanced antigen dissemination and T-cell priming. In an orthotopic rat TACE model, the combination of DOX-loaded RC6CaAlgMS with PD-L1 blockade achieved complete tumor eradication. Collectively, this study establishes a multifunctional microsphere platform that effectively remodels and overcomes the post-TACE immunosuppressive TME, offering a potent strategy for integrating embolization with immunotherapy in HCC."

This study evaluates the therapeutic potential of exosomes derived from induced pluripotent stem cell-derived mesenchymal stem cells (iPSCMSC-exo) versus umbilical cord-derived MSC exosomes (hUCMSC-exo) for POI intervention. In vitro, both exosome types enhanced migration and tube formation of human umbilical vein endothelial cells (HUVECs), while iPSCMSC-exo additionally promoted proliferation. iPSCMSC-exo attenuated cisplatin-induced granulosa cell apoptosis, while both types suppressed p21-mediated cell cycle arrest. In the cisplatin-induced POI mouse model, exosome treatment effectively restored Follicle-stimulating hormone (FSH) levels. However, the therapeutic efficacy of exosomes in restoring anti-M\u00fcllerian hormone (AMH) levels and follicle counts was limited, as confirmed by synchrotron radiation microtomography revealing persistent structural depletion. Notably, iPSCMSC-exo demonstrated functional outcomes similar to hUCMSC-exo.

In particular, advanced functionalization strategies have largely enhanced exosomal therapeutic efficacy in\u00a0vivo.

In this review, we systematically summarize exosome-based therapeutic strategies for CVDs, along with state-of-art functionalization approaches to optimize exosomal cargo loading and targeted delivery. We further provide a comprehensive overview of TCM-mediated exosomal regulation. We found that TCM and TCM-derived chemicals can optimize exosomal cargo loading, especially the loading of microRNAs (miRNAs) and bioactive chemicals. More importantly, TCM and chemicals can promote exosomal secretion, which provides new avenues for exosomal-scale production. Besides, there are synergistic effects between exosomes and TCM when co-administered. Collectively, exosome-based systems hold great promise for CVD therapy, and TCM provides novel strategies for exosomal functionalization, which substantially enhances exosomal-mediated therapeutic efficacy for CVDs."

Current methods of diagnosing OSCC use liquid biopsy technologies (ctDNA/microRNAs/exosomes) instead of relying solely on traditional methods such as open surgical biopsy. Liquid biopsy technologies provide non-invasive ways to detect and monitor OSCC in early stages, compared with traditional open surgical biopsy methods. Treatment of OSCC currently relies on chemotherapeutics (cisplatin/5-FU), radiotherapy, and targeted agents (cetuximab). However, resistance is acquired due to TME remodelling (tumor microenvironment) and/or due to epithelial-mesenchymal transition (EMT) through processes such as ABC transporter efflux. This review elucidates key molecular mechanisms, including PD-L1-mediated immune evasion, PI3K/AKT/mTOR hyperactivation, EGFR overexpression, and NF-\u03baB-driven inflammation, which promote proliferation, metastasis, and therapy resistance. One area of study involves the use of nanotechnology to convert phytocompounds (medicinal plants) into therapeutic agents by embedding phytocompounds into nanoparticles created using green synthesis techniques. EPR (Enhanced Permeability and Retention), ligand functionalization for OSCC targeting, improved bioavailability, and reduced toxicity are all advantages that the aforementioned systems provide, offering an opportunity to synergistically develop new therapies with chemotherapeutics for overcoming resistance. While numerous preclinical studies demonstrate that these newly developed therapies show increased efficacy compared with current therapy options, further work is needed in areas such as standardization, scaling, and clinical translation. As such, the importance of developing pathway-informed diagnostic tests and developing therapies that exploit pathway-specific activity with phytocompounds is emphasized. In addition, large-scale studies should be considered to evaluate the effectiveness of a pathway-informed approach in assessing and differentiating OSCC and personalized therapy strategies, to improve OSCC survival outcomes."

Nevertheless, despite considerable progress in elucidating its molecular background, early diagnosis and accurate stratification of disease progression remain challenging when relying on conventional clinical biomarkers such as albuminuria and estimated glomerular filtration rate (eGFR). Growing evidence indicates that DKD is driven by interconnected pathogenic mechanisms, including chronic hyperglycemia, activation of the protein kinase C (PKC) signaling pathway, renin-angiotensin-aldosterone system (RAAS) dysregulation, oxidative stress, inflammatory cascades, and immune system activation involving Toll-like receptors (TLR) and the NLRP3 inflammasome. These processes collectively contribute to endothelial dysfunction, podocyte injury, extracellular matrix accumulation, and progressive renal fibrosis. Exosomes and their molecular cargo, particularly miRNAs, have emerged as promising regulators and non-invasive biomarkers reflecting ongoing renal injury. Urinary exosomal microRNAs (uEV-miRNAs) are of interest due to their stability in biological fluids and their direct origin from nephron segments, enabling real-time reflection of renal pathophysiology. Accumulating studies suggest that differentially expressed microRNAs (miRNAs), including miR-21-5p, miR-30a-5p, miR-192-5p, and miR-142-3p, are closely associated with key pathways in DN. However, their clinical translation remains limited by methodological heterogeneity, the lack of standardized isolation protocols, and insufficient validation in large longitudinal cohorts. This review navigates the current landscape of knowledge on the molecular mechanisms underlying DKD and examines the emerging role of uEV-miRNAs as diagnostic biomarkers. Altogether, uEV-miRNAs offer a promising avenue for improving early detection, risk stratification, and disease monitoring in DKD."

The hydrogel was synthesized using polyethylene glycol (PEG), 2-hydroxyethyl methacrylate (HEMA), acrylic acid (AA), with N,N'-methylene bisacrylamide (MBA) as a cross-linker and potassium persulfate (KPS) as an initiator. The hydrogel's structural integrity and formation were confirmed through Fourier-transform infrared spectroscopy (FTIR), scanning electron microscopy (SEM), differential scanning calorimetry (DSC), and swelling studies. It is noteworthy that the hydrogel exhibits a different pH-dependent swelling behaviour, which expands under alkaline conditions and maintains its compact structure under acidic conditions. The content of acrylic acid contributed to the high-water retention and the swelling profile indicated that the product was suitable for the specific release of the drug at the site. The in-vitro release of rabeprazole sodium at acidic pH is very low, thus protecting rabeprazole sodium from premature degradation in the stomach; however, controlled release of rabeprazole sodium was achieved at intestinal pH via a non-Fickian diffusion mechanism (Korsmeyer-Peppas n = 0.40-0.62, Higuchi R\u00b2 = 0.991-0.996) over 12 h. Moreover, in-vivo acute toxicity studies indicated that the hydrogel is highly biocompatible, suggesting it is safe for use in future therapeutic applications. Overall, the PEG (HEMA-co-AA) hydrogel represents a versatile vehicle for the controlled and local administration of acid-labile pharmaceuticals, thereby promoting increased therapeutic efficacy."

The physicochemical stability and targeting efficiency of Man-Exos were evaluated both in vitro and in vivo. Man-Exos exhibited high stability in various conditions and showed significantly enhanced binding affinity to LSECs compared to non-targeted exosomes. Notably, in a co-culture system of LSECs and macrophages, Man-Exos demonstrated superior selectivity for LSECs. In vivo biodistribution studies further confirmed that Man-Exos predominantly accumulated in the liver, specifically colocalizing with LSECs for up to 48\u2009h. Our findings suggest that Man-Exos can serve as a highly efficient and stable delivery platform for LSEC-targeted therapy, providing a promising strategy for enhancing the translational potential of exosome-based regenerative medicine in liver fibrosis."

The core mechanisms underlying these diseases include impaired T-cell and B-cell immune tolerance, abnormal cytokine production, and aberrant activation of related signaling pathways. Conventional treatments primarily focus on suppressing immune responses, but their efficacy remains limited and they are often associated with substantial side effects. Nanomedicine leverages nanoscale materials to enable precise diagnosis and targeted therapy. Nanocarriers can penetrate biological barriers, enhance cellular uptake, and prolong circulation time in vivo, demonstrating considerable potential for drug delivery. Common nanoscale drug delivery platforms include nanoparticles, polymeric micelles, liposomes, dendrimers, mesoporous materials, hydrogels, and exosomes. Each carrier type possesses distinct characteristics in terms of drug-loading capacity, stability, responsiveness, and biocompatibility, thereby enabling targeted delivery and controlled release. This review summarizes recent advances in nano-delivery technologies for three representative chronic autoimmune diseases: diabetes mellitus (DM), inflammatory bowel disease (IBD), and rheumatoid arthritis (RA). Nano-delivery systems can improve therapeutic outcomes by optimizing drug delivery, targeting complications, and modulating the pathological microenvironment. They enhance drug bioavailability, reduce off-target and systemic adverse effects, and provide novel strategies for the precise and efficient treatment of chronic autoimmune diseases."

However, their specific roles and mechanisms in Alzheimer's disease (AD) therapy have not yet been systematically investigated. In this study, the rabies virus glycoprotein-targeting peptide (RVG-29) was conjugated to the surface of young plasma-derived EXOs to construct RVG-engineered EXOs (RVG-EXOs), and their therapeutic potential and underlying mechanisms in AD models were systematically evaluated. In 3\u00d7Tg AD model mice, exogenous administration of young plasma-derived EXOs and their engineered product (RVG-EXOs) revealed that RVG-EXOs could more efficiently enter brain tissue and target neurons, significantly reduce A\u03b2 plaque and phosphorylated Tau (P-Tau) pathological deposition, restore synaptic structure, promote neuronal survival, and improve cognitive behavior. Mechanistic studies demonstrated that RVG-EXOs inhibited RPTOR expression, thereby activating the autophagy pathway and promoting the clearance of pathological proteins. Both in vitro and in vivo experiments confirmed that overexpression of RPTOR significantly suppressed the therapeutic effects of RVG-EXOs. single-cell transcriptomic profiling further revealed that RVG-EXOs not only increased neuronal proportion and modulated excitatory/inhibitory neuronal balance but also reshaped the microglial landscape by reducing deleterious disease-associated while increasing homeostatic surveillant microglia. In summary, this study not only reveals for the first time the potential value of young plasma-derived EXOs in AD treatment but also, through RVG engineering strategies and the elucidation of the RPTOR-autophagy mechanism, provides new insights for targeted therapy of neurodegenerative diseases."

Ischemia triggers robust microglial activation, yet the precise regulatory mechanisms underlying microglial functional reprogramming remain incompletely understood. Here, we demonstrate that excessive mitophagy drives metabolic energy failure in microglia following cerebral ischemia, resulting in impaired phagocytosis and exacerbated neuroinflammation. Analysis of single-cell RNA-sequencing data from mouse brains in the sham, transient middle cerebral artery occlusion (tMCAO, mMCAO), and permanent middle cerebral artery occlusion (pMCAO, sMCAO) groups revealed that mitophagy was markedly activated in microglia under sustained ischemia and was associated with impaired phagocytic and cytoskeletal pathways. In vitro oxygen-glucose deprivation (OGD) assays showed that phagocytosis of apoptotic neurons by microglia induced upregulation of Drp1, triggering excessive mitochondrial fission and mitophagy, which caused ATP depletion and reduced clearance capacity. The mitophagy inhibitor 3-methyladenine alleviated inflammatory responses but failed to restore mitochondrial quality. In contrast, 3-n-butylphthalide (NBP) stabilized mitochondrial membrane potential, restored ATP production, and improved microglial phagocytic defects and inflammation. To achieve targeted delivery, we constructed BV2 microglia-derived exosomes encapsulating NBP (BV2exo@ NBP), which efficiently enhanced drug accumulation in ischemic lesions and significantly improved neurological outcomes in stroked mice. These results identify excessive mitophagy as a core mechanism underlying microglial energy crisis after cerebral ischemia and provide a mitochondria-targeted therapeutic strategy for ischemic stroke. Importantly, the neuroprotective efficacy, mitochondrial restoration, and anti-inflammatory effects of BM@NEB were fully recapitulated in 18-month-old aged mice, a clinically relevant model that more closely reflects the stroke patient population, supporting the translational potential of this exosome-based therapeutic strategy."

Moreover, the therapeutic efficacy of exosomes can be substantially enhanced through functional modifications and the incorporation of bioactive molecules. In this study, the MSCs were cultured under two-dimensional (2D) and three-dimensional (3D) cell culture conditions. The culture supernatants were collected for isolating exosomes. The characteristics and yields of exosomes from 2D and 3D cultures were detected by nanoparticle tracking analysis (NTA), transmission electron microscopy (TEM), western blot analysis, and bicinchoninic acid (BCA) assay. Subsequently, 3D exosomes were loaded with miR-99b-5p and modified with iRGD peptide were formed into a new engineered exosome, designated as iRGD-Exo-miR-99b-5p. The effects of these engineered exosomes on the progression of colorectal cancer (CRC) were assessed through a series of in vivo and in vitro experiments. The 3D-cultured MSCs exhibited a higher yield of exosomes and enhanced uptake by CRC cells. Further in vitro experiments demonstrated that 3D-exosomes loaded with miR-99b-5p effectively inhibit the proliferation, invasion, migration and epithelial-mesenchymal transition (EMT) of CRC cells. Results from a xenograft tumor model indicate that iRGD-modified exosomes were significantly enriched at tumor sites. Furthermore, exosomes modified with iRGD and loaded with miR-99b-5p were employed for CRC treatment, resulting in substantial tumor growth inhibition and enhanced the chemotherapy efficacy of 5-fluorouracil (5-FU) in vivo, without inducing notable toxicity or side effects. Mechanistically, exosome-mediated delivery of miR-99b-5p downregulated FGFR3 expression, thereby inhibiting the activation of the PI3K/AKt signaling pathway and promoting ferroptosis, ultimately attenuating CRC progression. Collectively, iRGD-modified 3D exosomes loaded with miR-99b-5p were able to specifically target tumor sites, thereby significantly suppressing CRC growth through the induction of ferroptosis via regulating the FGFR3/PI3K/AKt signaling pathway. These findings suggest that functional engineering and bioactive loading of 3D-exosomes derived from MSCs represent a promising strategy for targeted cancer therapy."

Exosomes (Exos) are key mediators of intercellular communication and promising vehicles for targeted therapy. This study aimed to investigate the function and underlying mechanism of exercise-derived exosomes (Exe-Exos) in SCI recovery. Circulating Exos were isolated from rats subjected to a 4-week treadmill Exe regimen and from sedentary controls. A gelatin methacrylate (GelMA) hydrogel microneedles (Hyd MNs) system was developed for the targeted, sustained delivery of these Exos directly to the injury epicenter at the T10 spinal segment in a rat SCI model. Using integrated in vitro and in vivo approaches, we showed that Exe-Exos significantly promoted motor function recovery, attenuated tissue damage, reduced apoptosis, and alleviated both inflammation and oxidative stress (Oxs) after SCI. Small RNA sequencing revealed that miR-151-3p is a key functional cargo that is enriched in Exe-Exos. Gain- and loss-of-function studies revealed that exosomal miR-151-3p exerts its protective effects by directly targeting the mitochondrial membrane protein ROMO1. This targeting led to the coordinated inhibition of the pro-apoptotic JNK/Caspase pathway, suppression of the NF-\u03baB-mediated inflammatory cascade, and activation of the Nrf2/HO-1 antioxidant axis. Collectively, our findings establish Exe-Exos, specifically exosomal miR-151-3p, as an exercise-responsive circulating signaling axis that orchestrates multifaceted protection against secondary injury after SCI, offering an innovative, mechanism-based strategy for neuroregenerative therapy."

In recent years, exosomes (Exos), nanoscale vesicles involved in intercellular communication, have attracted increasing attention for their roles in the formation and spread of MDR. A growing body of evidence suggests that Exos mediate the transfer of resistance-related molecular signals among drug-resistant cancer cells, drug-sensitive cancer cells, and stromal cells, such as cancer-associated fibroblasts and tumor-associated macrophages, through the selective packaging of noncoding RNAs, functional proteins, and metabolic regulators. These molecular signals may induce the reprogramming of signaling pathways, metabolism, and epigenetic states in recipient cells, thereby promoting the acquisition of cancer stem cell-like properties and a drug-resistant phenotype. In turn, these changes may contribute to the establishment of a drug resistance-supporting tumor microenvironment. This review systematically summarizes the molecular mechanisms by which Exos contribute to multidrug resistance, with a particular focus on their roles in cargo sorting, microenvironmental crosstalk, and the functional reprogramming of recipient cells. It also discusses their potential for clinical translation in resistance monitoring and reversal therapy.

The secreted extracellular vesicles (EVs) of organoids, in particular the small-sized EV subset referred as exosomes (30-200\u00a0nm), have emerged as novel therapeutics in regenerative medicine. This study investigated the encapsulation and controlled release of human spinal cord organoid (hSCO)-derived EVs in viscoelastic hyaluronic acid (HA) hydrogels and assessed their impact on organoid patterning. A series of pH-responsive hydrogels were fabricated, leading to sustained EV release regulated by viscoelastic properties. The pH of these hydrogels decreased from 9 to 7 during incubation, which altered hydrogel viscoelasticity, thereby modulating EV release kinetics. In addition, EV-loaded hydrogels regulated key hSCO patterning markers such as DBX1 and ISL1. Furthermore, these EVs in hydrogels can cross a modeled blood-spinal cord barrier and provide cross-barrier capability for delivery. Taken together, the organoid-secreted EVs in viscoelastic HA hydrogels can be released at a controlled rate and have potential to regulate spinal cord organoid patterning.

This review highlights recent advances in exosome biology, cargo-sorting mechanisms, and engineering strategies designed to enhance therapeutic delivery and targeting within the central nervous system. Particular emphasis is placed on the application of engineered exosomes in neurodegenerative diseases, stroke, spinal cord injury, neuropathic pain, and neuroinflammatory disorders. In addition, we discuss how exosomes compare with conventional delivery platforms and critically examine the major barriers limiting their clinical translation, including heterogeneity, scalability, reproducibility, purity, and regulatory standardization. By integrating mechanistic insights with translational perspectives, this review provides a framework for the rational design and future clinical implementation of exosome-based nanomedicines for neurological disorders. Relevant literature was identified through searches of PubMed, Scopus, Web of Science, and Google Scholar. Publications available from database inception through [Month Year] were screened using combinations of keywords including \"exosomes,\" \"extracellular vesicles,\" \"neurological disorders,\" \"brain-targeted delivery,\" \"exosome engineering,\" \"drug delivery,\" and \"clinical trials.\" Additional relevant articles were identified through manual searches of reference lists from selected studies and recent reviews. Exosomes are tiny natural particles released by cells that act as messengers, carrying proteins and genetic material between cells. Scientists are increasingly studying these particles because they may help deliver medicines to the brain and spinal cord, where many treatments struggle to reach due to protective barriers. This review explains how exosomes are formed, how they can be modified to carry drugs or therapeutic molecules, and how they may help treat diseases affecting the nervous system, including Alzheimer\u2019s disease, Parkinson\u2019s disease, stroke, multiple sclerosis, spinal cord injury, and certain neuropsychiatric disorders.We also discuss the advantages of exosomes compared with conventional drug delivery systems and summarize recent advances in engineering strategies that improve their targeting abilities. Although laboratory studies have produced encouraging results, many challenges remain before exosome-based therapies can become routine treatments. These include difficulties related to large-scale production, quality control, safety, and ensuring that exosomes reach the desired tissues without causing unwanted effects.In addition, this review highlights current clinical studies and discusses the steps needed to translate these discoveries into real-world therapies. Overall, exosomes represent an exciting and rapidly evolving area of research that may contribute to the development of safer and more effective treatments for neurological disorders in the future."

China (n=370) has the largest number of publications, and representative institutions include Fudan University (n=19), Chinese Academy of Medical Sciences (n=15), and Shanghai Jiao Tong University (n=14). The USA (94.65) demonstrates the most significant academic influence. Research hotspots have gradually shifted from the correlation between the early macrophage polarization phenotype and the pathological characteristics of lung cancer to molecular mechanisms such as signaling pathways, metabolic reprogramming, and exosomes, and have further expanded to the directions of nanoparticle targeted delivery and clinical translation of immune checkpoint inhibitors. The research in this field has advanced from phenotypic description to mechanism integration and translational research, with nano-intervention and immune regulation being the cutting-edge directions. In the future, attention should be focused on the clinical translation pathways of personalized regulation strategies."

"displayText": "Even though this fact check looked at unique up-to-date abstracts, new evidence may refute this answer in the future. 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]\n\"The conjugation of plant-derived nanovesicles with pH-responsive or enzyme-cleavable 'hitchhiker' peptides enables triggered release within the lymphatic pre-metastatic niche, thereby enhancing the therapeutic payload concentration specifically at sites of active lymphangiogenesis in patients with early-stage lymphatic metastasis.\"\n\nThis claim is Plausible (5/7) based on the evidence, though direct verification of \"plant-derived nanovesicles\" specifically modified with \"hitchhiker\" peptides for \"lymphatic pre-metastatic niche\" targeting is currently an extrapolation of parallel technologies. The provided literature confirms that (1) plant-derived nanovesicles have therapeutic potential in inflammatory and cancer models, (2) pH-responsive and enzyme-cleavable linkers are effective for site-specific delivery in these models, and (3) targeting biomarkers of lymphatic metastasis (such as CCR2 or VEGF-C pathways) can enhance delivery to the metastatic niche. However, a single study synthesizing all these specific components (plant-EVs + hitchhiker peptide + lymphatic targeting) is not explicitly detailed in the provided set.\n\n### [ABSTRACT & REWRITTEN CLAIM]\nPlant-derived extracellular vesicles (EVs) are emerging as versatile, biocompatible platforms for targeted cancer therapy. While current literature establishes the efficacy of engineering plant-EVs with pH-responsive shells or targeting ligands to modulate tumor environments, the specific coupling of \"hitchhiker\" peptide-mediated lymph node (LN) targeting with pH-triggered payload release in a pre-metastatic niche remains a theoretical design paradigm supported by the synergistic capabilities of these distinct technologies.\n\n### [INTRODUCTION & JUSTIFICATION]\nThe therapeutic application of extracellular vesicles (EVs) has expanded from mere drug vehicles to intelligent, responsive nanoplatforms. By exploiting the acidic microenvironment inherent to tumor progression and sites of inflammation, researchers have developed pH-responsive coatings that ensure cargo protection during circulation and selective release upon accumulation. In the context of early lymphatic metastasis, the pre-metastatic niche provides a distinct physiological landscape. Strategies involving nanoparticle hitchhiking\u2014such as the MCP1-derived peptides\u2014have demonstrated the ability to exploit monocyte-mediated lymphatic transport to achieve significant accumulation in metastatic nodes. By integrating these \"hitchhiker\" mechanisms with the structural stability and cargo-loading capabilities of plant-derived vesicles, it is mechanistically plausible that therapeutic efficacy in nodal disease could be substantially improved. The literature supports that \"Rational engineering strategies, including surface modification, self-loading hybridization, genetic manipulation, and pH-responsive coating, can optimize the therapeutic performance of BEVs.\" Furthermore, the use of targeted agents, such as CCR2-binding peptides, provides a clear roadmap for achieving \"monocyte hitchhiking,\" which is crucial as \"LN targeting was dependent on monocyte hitchhiking, as monocyte depletion decreased accumulation by >70%.\"\n\n### [DISCUSSION: NOVEL & OVERLOOKED]\n* Plant-derived nanovesicles exhibit significant cross-kingdom therapeutic potential due to their conservation of metabolic and immune-related pathways.\n* The use of \"hitchhiking\" onto endogenous circulating cells, such as monocytes, allows for significantly increased transport across the lymphatic endothelium.\n* pH-responsive hydrogel shells enable the protection of sensitive cargos (like siRNAs or enzymes) from premature degradation in the systemic circulation.\n* Targeting the CCR2 pathway allows for the specific recognition of metastatic lymph nodes, where this biomarker is highly expressed.\n* Integration of plant-EVs with inorganic materials (e.g., SPIONs or ZIF-8) offers dual-modal therapy, enabling both spatial guidance and triggered drug release.\n* Pre-metastatic niche formation involves active remodeling of the lymphovascular architecture, providing a window of opportunity for targeted intervention before overt tumor colonization.\n* Microfluidic technology facilitates the fabrication of uniform-sized nanocarriers that improve standardized, large-scale manufacturing potential.\n\n### [EVIDENCE, METHODOLOGY & CITATIONS]\n1.

Magnetic resonance imaging (MRI) has been utilized as a noninvasive alternative but is limited by low sensitivity, with only \u223c35% of LN metastases detected, as clinical contrast agents cannot discriminate between healthy and metastatic LNs due to nonspecific accumulation. Nanoparticles targeted to the C-C chemokine receptor 2 (CCR2), a biomarker highly expressed in metastatic LNs, have the potential to guide the delivery of contrast agents, improving the sensitivity of MRI. Additionally, cancer cells in metastatic LNs produce monocyte chemotactic protein 1 (MCP1), which binds to CCR2+ inflammatory monocytes and stimulates their migration. Thus, the molecular targeting of CCR2 may enable nanoparticle hitchhiking onto monocytes, providing an additional mechanism for metastatic LN targeting and early detection. Hence, we developed micelles incorporating gadolinium (Gd) and peptides derived from the CCR2-binding motif of MCP1 (MCP1-Gd) and evaluated the potential of MCP1-Gd to detect LN metastasis. When incubated with migrating monocytes in vitro, MCP1-Gd transport across lymphatic endothelium increased 2-fold relative to nontargeting controls. After administration into mouse models with initial LN metastasis and recurrent LN metastasis, MCP1-Gd detected metastatic LNs by increasing MRI signal by 30-50% relative to healthy LNs. Furthermore, LN targeting was dependent on monocyte hitchhiking, as monocyte depletion decreased accumulation by >70%. Herein, we present a nanoparticle contrast agent for MRI detection of LN metastasis mediated by CCR2-targeting and demonstrate the potential of monocyte hitchhiking for enhanced nanoparticle delivery.\n\nID: 42571391\nTitle: Linker-directed lipid-antigen conjugates co-enhance lymph node targeting and antigen presentation for potent T cell immunity.\nAbstract: The clinical efficacy of peptide-based cancer vaccines is limited by inefficient lymphatic delivery and suboptimal antigen presentation. Here, we report a rationally engineered class of lipid-antigen conjugates that co-enhance lymph node (LN) targeting and antigen-presenting cell (APC) uptake through molecular-level structural optimization. By systematically varying lipid tail composition and linker chemistry, we identify a lead construct (dOA-K-O) incorporating a dioleic acid (dOA) lipid tail and an L-lysine (K) linker, which outperforms the clinically used DSPE-PEG2000 conjugate (DSPE-O). Mechanistically, the positively charged L-lysine linker promotes albumin binding while reducing excessive self-assembly, enhancing lymphatic trafficking and facilitating APC internalization. In vivo, dOA-K-O elicits robust antigen cross-presentation and induces an 8-fold increase in antigen-specific CD8+ T cell responses compared to unmodified antigenic peptide and 3-fold higher than DSPE-O. This enhanced cellular immunity translates into marked tumor suppression in both prophylactic and therapeutic B16-OVA melanoma models. Our results establish a design paradigm in which linker chemistry and lipid tail composition are synergistically optimized to boost the immunogenicity of peptide vaccines for cancer immunotherapy, which may provide a chemical and structural basis for the optimization of peptide-based vaccine delivery systems.\n\nID: 42561425\nTitle: Bacterial extracellular vesicles: mechanisms, engineering strategies, and therapeutic potential for inflammatory bowel disease.\nAbstract: Clinical management of inflammatory bowel disease (IBD) is hampered by limited therapeutic targets, primary non-response, secondary loss of efficacy, and safety risks, which undermine clinical outcomes. Probiotics and postbiotics represent promising preclinical candidates to alleviate these unmet clinical bottlenecks. Bacterial extracellular vesicles (BEVs) are naturally secreted bacterial nanovesicles carrying abundant bioactive cargos, whose bioactivity and safety are highly strain-dependent. Probiotics-derived BEVs can remodel gut homeostasis, repair epithelial barriers, and regulate mucosal immunity to suppress the inflammatory vicious cycle in IBD, while pathogen-/pathobiont-derived BEVs loaded with lipopolysaccharide and virulence factors exacerbate intestinal inflammation. Native BEVs are restricted by low cargo loading, poor gastrointestinal stability and inadequate colon tropism. Rational engineering strategies, including surface modification, self-loading hybridization, genetic manipulation, and pH-responsive coating, can optimize the therapeutic performance of BEVs. This review systematically summarizes BEVs biological mechanisms, engineering approaches, and translational obstacles and outlines prospects for the design of intelligent multifunctional BEVs and standardized large-scale manufacturing as future directions, providing theoretical support for oral BEVs nanotherapies against IBD.\n\nID: 42395337\nTitle: Intelligent responsive alloy scaffold temporally regulates the immune-osteogenic axis for the treatment of infectious bone defects.\nAbstract: Excessive immune activation induced by persistent bacterial infection, which further impairs osteogenic function, is a crucial factor contributing to the poor healing of infectious bone defects. Therapeutic strategies targeting a single link often yield limited efficacy. Therefore, we developed an alloy scaffold bone graft (TCMP) with pH-responsive sequential regulation of the immuno-osteogenic axis. During the infection phase, the scaffold mainly releases copper ions to exert potent antibacterial activity, and simultaneously releases Pueraria lobata-derived exosome-like nanovesicles (PELNs) in a pH-responsive manner, thereby effectively suppressing the early inflammatory cytokine storm. In the osteogenesis phase, the scaffold switches its release pattern to sustained magnesium ion release, accompanied by low-level sustained release of PELNs, which targets mesenchymal stem cells, vascular endothelial cells and macrophages to promote the directional recruitment and migration of stem cells, accelerate their osteogenic differentiation, improve the inflammatory immune microenvironment and enhance angiogenesis; consistent with the physiological characteristics of extremely scarce osteoclasts in the early stage of implantation, Mg2+ exerts no regulatory effect on osteoclasts in this study. Mechanistically, TCMP mediates dual-pathway synergistic therapy for infectious bone defects by inhibiting the advanced glycation end products/receptor for advanced glycation end products/nuclear factor-\u03baB (AGEs/RAGE/NF-\u03baB) pathway and activating the hypoxia-inducible factor-1 (HIF-1) signaling pathway. In conclusion, the developed TCMP alloy scaffold integrates the \"trinity\" functions of antibacterial activity, anti-inflammation, and osteogenesis, comprehensively breaking the vicious cycle of bacterial infection-excessive inflammatory activation-impaired osteogenic capacity, and providing a therapeutic strategy with excellent translational potential for clinical practice.\n\nID: 42383350\nTitle: Mechanoreceptor plexin D1 regulates lymphatic valve morphogenesis and lymphedema pathogenesis.\nAbstract: Lymphatic valves are essential for maintaining tissue fluid homeostasis, and their dysfunction leads to lymphedema, a morbid and disfiguring disease without a cure. Mechanical forces due to lymph flow are required for proper lymphatic valve development, yet it remains unclear how lymphatic endothelial cells (LECs) sense and decode mechanical signals. In this study, we identify the cell guidance semaphorin receptor plexin D1 (PLXND1) as a lymphatic mechanosensor required for lymphatic valve morphogenesis. Conditional genetic ablation of Plxnd1 in LECs caused major defects in lymphatic valve development in 2 different lymphatic vascular beds. Mechanistically, PLXND1 acted as a mechanosensor within a lymphatic mechanocomplex, initiating distinct mechanical signals and activating the lymphatic valve transcriptional program through an unconventional pathway. Screening of patients with primary lymphedema identified PLXND1 missense variants, and functional analysis established 2 pathogenic variants that selectively disrupt the ligand versus mechanosensing functions of this receptor. Variants associated with lymphedema in members of the mechanocomplex disrupted its formation, underscoring the central role of this complex in lymphatic valve biology. Our work uncovers a mechanosensing mechanism guiding lymphatic valve development, and has profound implications for the understanding and treatment of primary lymphedema in humans.\n\nID: 42349053\nTitle: Neutrophil-hitchhiking nanodrug precisely silences neutrophil activation and rebuilds immune homeostasis in rheumatoid arthritis without compromising host defense.\nAbstract: Rheumatoid arthritis (RA) is a chronic autoimmune disease, and current antirheumatic drugs have poor efficacy or cause considerable systemic adverse reactions. Neutrophil activation is a central driver of RA pathogenesis; however, approaches that curb pathogenic neutrophil activity while preserving host defense are lacking. In patients with RA, we identified spleen tyrosine kinase (SYK) as a key upstream regulator whose aberrant activation drives neutrophil hyperactivation, neutrophil extracellular trap (NET) formation, inflammatory mediator release, and delayed apoptosis, while preserving antimicrobial function. Moreover, we engineered a HSA-AAPV-TKI (HAT) nanodrug by conjugating human serum albumin (HSA) to a SYK-targeted tyrosine kinase inhibitor (TKI) via a neutrophil elastase-cleavable AAPV peptide linker (Ala-Ala-Pro-Val). HAT is preferentially internalized by circulating neutrophils in CIA mice, traffics with them to inflamed joints, and releases the inhibitor in response to local neutrophil activation, thereby attenuating SYK signaling and pathogenic neutrophil functions while largely preserving antimicrobial activity. In a collagen-induced arthritis mouse model, HAT significantly reduced joint swelling, arthritis scores, and structural joint damage without impairing host defense. This strategy establishes a new RA therapeutic avenue that reconciles potent efficacy with immune safety and represents a milestone toward translational neutrophil-targeted therapy.\n\nID: 42338019\nTitle: Exosomal Oleic Acid Promotes Lymphangiogenesis and Nodal Metastasis in Cervical Cancer via the AKT/mTOR Pathway.\nAbstract: Cervical cancer (CC) exhibits a pronounced tropism for regional lymphatic dissemination, a process driven by tumor-associated lymphangiogenesis. While metabolites within the metastatic niche are increasingly recognized as determinants of organotropic metastasis, the role of exosome-mediated metabolite transfer in tumor-lymphatic endothelial cell (LEC) crosstalk remains largely unexplored. Here, we demonstrate that oleic acid (OA) is significantly enriched in both CC lymph node metastases and the peritumoral lymphatic microenvironment. Exosomes derived from highly metastatic CC cells actively package OA in a manner dependent on stearoyl-CoA desaturase (SCD), the rate-limiting enzyme of de novo fatty acid synthesis. Upon internalization by LECs, exosomal OA triggers the AKT/mTOR signaling axis, eliciting robust LEC proliferation and endothelial-to-mesenchymal transition (EndMT), thereby fostering lymphangiogenesis and nodal colonization. Knockdown of SCD abolishes these pro-lymphangiogenic effects, a deficit fully reversed by the reconstitution of OA-loaded exosomes. In vivo, exosomes from SCD-silenced cells exhibit a severely compromised capacity to drive primary tumor growth, intratumoral lymphangiogenesis, and lymph node metastasis (LNM). Notably, free OA administration exerts substantially weaker effects than its exosomal counterpart, underscoring the superior efficiency of exosome-mediated metabolite trafficking. Clinically, FASN and SCD expression are significantly upregulated in lymph node-positive specimens and positively correlate with lymphatic vessel density and p-AKT levels. Furthermore, circulating exosomal OA levels are significantly elevated in patients with nodal involvement, suggesting its potential as a non-invasive diagnostic biomarker. Collectively, our findings establish a paradigm wherein tumor-derived exosomes function as specialized vehicles for intercellular OA transfer, activating the AKT/mTOR pathway to license lymphangiogenic reprogramming. This work identifies exosomal metabolite shuttling as a central node in tumor-lymphatic communication and proposes targeting OA synthesis or exosomal delivery as a promising therapeutic strategy against CC metastasis.\n\nID: 42299841\nTitle: Tumor-Derived Exosomal piR-hsa-28212 Promotes Lymphatic Metastasis in Breast Cancer.\nAbstract: Lymph node (LN) metastasis is a critical indicator of poor prognosis in breast cancer (BC). BC-derived exosomes influence intercellular communication within the tumor microenvironment, driving metastatic progression. However, the precise mechanisms by which exosomes facilitate LN metastasis in BC remain unclear. We performed small RNA sequencing on serum exosomes to identify Piwi-interacting RNAs (piRNAs) associated with BC LN metastasis. Functional investigations of exosomal piR-hsa-28212 included in\u00a0vitro assays for migration and tube formation of human lymphatic endothelial cells (HLECs), alongside an in\u00a0vivo footpad-popliteal LN metastasis model. Specific interactions between piR-hsa-28212 and TBX1 (T-box transcription factor 1), as well as TBX1 and VEGF receptor 3 (VEGFR3), were validated through luciferase reporter assays. The stability of TBX1 mRNA was analyzed by actinomycin D assay. RNA pulldown, RNA immunoprecipitation (RIP), and RNA fluorescence in\u00a0situ hybridization (FISH) assays were conducted to explore the interaction between piR-hsa-28212 and METTL3. PiR-hsa-28212 was significantly upregulated in serum exosomes of BC patients with LN metastasis. Exosomal piR-hsa-28212 enhanced HLECs migration and tube formation in\u00a0vitro and promoted lymphangiogenesis and LN metastasis in\u00a0vivo. Mechanistically, exosomal piR-hsa-28212 transferred from BC cells to HLECs stabilized TBX1 mRNA, thereby upregulating VEGFR3 expression. In BC cells, piR-hsa-28212 directly bound to and stabilized METTL3 protein, modulating N6-methyladenosine (m6A) methylation of vascular endothelial growth factor C (VEGFC) mRNA and consequently increasing VEGFC expression and secretion. Collectively, these findings reveal an exosome-mediated piRNA regulatory mechanism that synergistically amplifies VEGFC/VEGFR3 signaling to drive LN metastasis in BC, highlighting piR-hsa-28212 as a potential therapeutic target.

Accumulating evidence now implicates meningeal lymphatic dysfunction as a pivotal contributor to the pathogenesis of Alzheimer's disease (AD). This review critically evaluates current neuroimaging techniques for assessing meningeal lymphatic function in humans, highlighting their technical limitations in capturing dynamic pathological changes specific to AD. We summarize recent advances demonstrating that meningeal lymphatic impairment exacerbates key AD hallmarks-including amyloid-\u03b2 (A\u03b2) and tau deposition, neuroimmune dysregulation, and myelin degradation-collectively accelerating disease progression. Building on these insights, we systematically analyse emerging therapeutic strategies aimed at enhancing meningeal lymphatic function, such as pharmacological approaches (e.g., vascular endothelial growth factor C (VEGF-C)-mediated lymphangiogenesis), physical interventions (e.g., transcranial photobiomodulation), and surgical techniques (e.g., cervical lymphaticovenous anastomosis). However, significant challenges remain, including the scarcity of direct human evidence linking meningeal lymphatic dysfunction to AD and the lack of standardized, noninvasive assessment tools. To address these gaps, we propose future fundamental and clinical research directions for meningeal lymphatic vessels and AD. By bridging mechanistic insights with translational applications, this review highlights the role of the meningeal lymphatic system as a promising yet underexplored target for AD modification.\n\nID: 42276484\nTitle: A pH-responsive hydrogel based on polysaccharides incorporated with honeysuckle-derived exosome-like nanovesicles for the management of infected wound.\nAbstract: The management of infected wounds is a major clinical challenge because the healing process is often obstructed by several related pathological factors, such as drug-resistant microbial infections, persistent inflammatory responses, oxidative stress, and impaired angiogenesis. In this study, we developed an injectable hydrogel (CTOHo) designed using honeysuckle-derived exosome-like nanovesicles (HoNVs) incorporated into a dynamic network created from carboxymethyl chitosan (CMCS), tannic acid (TA), and oxidised sodium alginate (OSA). HoNVs were isolated from fresh honeysuckle and characterised. The CTO-Ho hydrogel is synthesised through a dynamic network structure composed of CMCS, OSA and TA and loaded with HoNVs. Systematic characterisation and evaluation of the physicochemical properties of the CTO-Ho hydrogel were performed. The antibacterial activity against S. aureus, E. coli and MRSA; macrophage polarisation; ROS scavenging; HUVEC migration/tube formation; and full-thickness S. aureus-infected rat wounds were evaluated over 14\u00a0days. The resulting hydrogel was found to possess high gelation kinetics, good injectability with accurate adherence to the wound topography, and the pH-sensitive release of HoNVs under acidic conditions. Bioactive phytochemicals, such as flavonoids, phenolic acids, and alkaloids, are enriched in HoNVs. The synergistic interaction between HoNVs and TA endows CTO-Ho with strong biocompatibility, promotes angiogenesis, suppresses inflammation, exhibits antimicrobial activity, and scavenges reactive oxygen species, greatly increasing the regeneration of infected tissues. This plant exosome-functionalised carbohydrate-based hydrogel system offers a holistic and clinically viable approach for the targeted treatment of complex infected wounds.\n\nID: 42252618\nTitle: Activatable Immunotheranostic Nanovesicles for Coordinated Phagocytic Reprogramming and Real-Time Immune Monitoring.\nAbstract: Cancer immunotherapy has revolutionized oncology, yet its efficacy against solid tumors remains severely hampered by the functional impairment and phenotypic skewing of immune cells within the tumor microenvironment. Here, we report a multifunctional nanoplatform that integrates potent immune reprogramming with real-time immune monitoring to enable both precise immunomodulation and dynamic assessment. We engineer genetically modified cell-derived nanovesicles codisplaying anti-CD47 nanobodies and calreticulin (CRT) signals to simultaneously block the CD47-SIRP\u03b1 \"don't eat me\" axis and deliver potent \"eat me\" cues, thereby promoting tumor cell phagocytosis and dendritic cell (DC) maturation. These nanovesicles, cloaked in a pH-responsive tannic acid-manganese (TA-Mn) shell, achieve systemic stability while enabling tumor-selective ligand exposure and Mn2+-mediated activation of the cGAS-STING pathway, further amplifying innate immune signaling. This coordinated modulation drives DC activation, augments antigen cross-presentation, and reprograms tumor-associated macrophages toward an M1 phenotype, eliciting robust CD8+ T cell responses and durable immunological memory. To enable spatiotemporal tracking of immune dynamics, the platform integrates a nitric oxide-activatable photoacoustic probe for in situ visualization of macrophage repolarization during therapy. Across multiple murine tumor models, this strategy eradicates established tumors, prevents metastasis, and confers long-term immune protection. Together, this study introduces a versatile and adaptive immunotherapeutic paradigm that couples activatable theranostics with robust immune reprogramming, advancing a new frontier in precision cancer immunotherapy.\n\nID: 42252274\nTitle: [Research progress on vascular endothelial growth factor C in meningeal lymphatic vessel-mediated clearance of amyloid \u03b2-protein].\nAbstract: Alzheimer's disease (AD) is a neurodegenerative disorder characterized by the abnormal deposition of amyloid \u03b2-protein (A\u03b2) as a core pathological feature. Meningeal lymphatic vessels are crucial for A\u03b2 clearance, and their dysfunction accelerates AD progression. Vascular endothelial growth factor C (VEGF-C), through activation of vascular endothelial growth factor receptor 3 and downstream pathways, synergistically promotes lymphangiogenesis, enhances lymphatic permeability, and regulates lymphatic fluid flow, thereby improving A\u03b2 clearance efficiency. Genetic factors and aging-related declines in VEGF-C further impair meningeal lymphatic function, creating a vicious cycle. This review summarizes the mechanisms by which VEGF-C regulates the structure and function of meningeal lymphatic to promote A\u03b2 clearance, synthesizes the evidence that genetic factors and aging contribute to meningeal lymphatic dysfunction through their effects on VEGF-C, and discusses the prospects of individualized intervention strategies for Alzheimer's disease based on VEGF-C-mediated modulation of meningeal lymphatics, aiming to provide insights for AD prevention and treatment. \u963f\u5c14\u8328\u6d77\u9ed8\u75c5\uff08AD\uff09\u662f\u4e00\u79cd\u4ee5\u03b2\u6dc0\u7c89\u6837\u86cb\u767d\uff08A\u03b2\uff09\u6c89\u79ef\u4e3a\u6838\u5fc3\u75c5\u7406\u6539\u53d8\u7684\u795e\u7ecf\u9000\u884c\u6027\u75be\u75c5\u3002\u8111\u819c\u6dcb\u5df4\u7ba1\u662fA\u03b2\u6e05\u9664\u7684\u91cd\u8981\u901a\u8def\uff0c\u5176\u529f\u80fd\u969c\u788d\u52a0\u901fAD\u8fdb\u5c55\u3002\u8840\u7ba1\u5185\u76ae\u751f\u957f\u56e0\u5b50C\uff08VEGF-C\uff09\u901a\u8fc7\u6fc0\u6d3b\u8840\u7ba1\u5185\u76ae\u751f\u957f\u56e0\u5b50\u53d7\u4f533\u53ca\u4e0b\u6e38\u4fe1\u53f7\u901a\u8def\uff0c\u534f\u540c\u4fc3\u8fdb\u6dcb\u5df4\u7ba1\u65b0\u751f\u3001\u589e\u5f3a\u6dcb\u5df4\u7ba1\u901a\u900f\u6027\u53ca\u8c03\u8282\u6dcb\u5df4\u6db2\u6d41\u52a8\uff0c\u63d0\u9ad8A\u03b2\u6e05\u9664\u6548\u7387\u3002\u9057\u4f20\u56e0\u7d20\u548c\u8870\u8001\u76f8\u5173\u56e0\u7d20\u5bfc\u81f4VEGF-C\u8870\u51cf\u8fdb\u800c\u524a\u5f31\u8111\u819c\u6dcb\u5df4\u7ba1\u529f\u80fd\uff0c\u5f62\u6210\u6076\u6027\u5faa\u73af\u3002\u672c\u6587\u7efc\u8ff0\u4e86VEGF-C\u8c03\u63a7\u8111\u819c\u6dcb\u5df4\u7ba1\u7ed3\u6784\u548c\u529f\u80fd\u4fc3\u8fdbA\u03b2\u6e05\u9664\u7684\u4f5c\u7528\u673a\u5236\uff0c\u603b\u7ed3\u4e86\u9057\u4f20\u548c\u8870\u8001\u901a\u8fc7\u5f71\u54cdVEGF-C\u5bfc\u81f4\u8111\u819c\u6dcb\u5df4\u7ba1\u529f\u80fd\u969c\u788d\u7684\u8bc1\u636e\uff0c\u5e76\u5c55\u671b\u4e86\u57fa\u4e8eVEGF-C\u8c03\u63a7\u8111\u819c\u6dcb\u5df4\u7ba1\u7684AD\u4e2a\u4f53\u5316\u5e72\u9884\u7b56\u7565\uff0c\u4ee5\u671f\u4e3aAD\u9632\u6cbb\u7814\u7a76\u63d0\u4f9b\u53c2\u8003\u3002.\n\nID: 42224999\nTitle: YBX1 takes actions on triggering M2-like polarization of macrophages and stabilizing CXCL8 mRNA to exhibit its metastatic potential in bladder cancer.\nAbstract: Patients diagnosed with bladder cancer (BCa) with lymph node (LN) metastasis face a grim prognosis with limited treatment options. We examined the relationship between Y-box binding protein 1 (YBX1) and tumor-associated macrophages (TAMs) concerning LN metastasis in BCa. Popliteal lymphatic metastasis model was constructed in Balb/c mice. Histological examinations were conducted using hematoxylin and eosin (HE) and Immunohistochemical staining. Flow cytometry detected M1/M2 polarization markers. Immunofluorescence staining tested distribution of interleukin enhancer binding factor 3 (ILF3) and YBX1 and macrophage markers. Transwell and tube formation assays assessed migration and angiogenesis. Enzyme-linked immunosorbent assay (ELISA) measured C-X-C motif chemokine ligand 8 (CXCL8), transforming growth factor beta (TGF-\u03b2), vascular endothelial growth factor A (VEGFA) and macrophage markers. Levels of mRNA and protein were measured by RT-qPCR and Western blot. Subcellular localization of ILF3 and CXCL8 was detected utilizing fluorescence in situ hybridization (FISH) assay. Exosomes derived from BCa cells were isolated and identified. RNA immunoprecipitation (RIP) and Co-immunoprecipitation (Co-IP) validated molecular interactions. Knockdown of YBX1 in BCa cells suppressed lymphangiogenesis in vitro and in vivo and reduced M2 macrophage polarization. CXCL8 levels, elevated in BCa patients, were positively correlated with YBX1 and M2 macrophage infiltration, and this elevation was reduced upon YBX1 knockdown. BCa cell-derived exosomes containing YBX1 were internalized by macrophages, where they were crucial for inducing M2-like polarization and promoting CXCL8 expression, ultimately stimulating angiogenesis and lymphangiogenesis. Mechanistically, YBX1 interacted with ILF3 to stabilize CXCL8 mRNA. By inducing macrophage M2-like polarization, YBX1 promoted lymphangiogenesis and lymphatic metastasis in BCa, which may provide novel clinical markers for LN metastatic BCa.\n\nID: 42001054\nTitle: Turmeric-derived exosome-coated ZIF-8 nanoplatform for targeted delivery of TGF-\u03b21 siRNA in the treatment of liver fibrosis.\nAbstract: Liver fibrosis constitutes a progressive pathological condition for which TGF-\u03b21 pathway-targeted siRNA therapy holds considerable therapeutic potential. Nevertheless, clinical application of TGF-\u03b21 siRNA is critically limited by inherent instability and inefficient delivery in vivo. In this study, we engineered an innovative siRNA delivery platform through the integration of turmeric-derived exosome-like nanovesicles (TDEs) with a metal-organic framework (ZIF-8) to generate TDEs@ZIF-8@TGF\u03b21siRNA nanoparticles, thereby enhancing siRNA delivery efficiency and therapeutic efficacy in liver fibrosis. Characterization revealed TDEs@ZIF-8@TGF\u03b21siRNA nanoparticles exhibited a well-defined nanostructure with a high TGF-\u03b21 siRNA encapsulation efficiency of 64.73%. Additionally, the system exhibited pH-responsive release and lysosomal escape capabilities, significantly enhancing siRNA stability and cellular uptake efficiency. In vitro, TDEs@ZIF-8@TGF\u03b21siRNA effectively inhibited hepatic stellate cells (HSCs) activation, reducing TGF-\u03b21, Collagen I, and CTGF mRNA levels by 78.6%, 72.1%, and 69.4%, respectively. In a CCl4-induced mouse model of liver fibrosis, TDEs@ZIF-8@TGF\u03b21siRNA treatment significantly improved hepatic function, reducing serum ALT and AST levels by 59.8% and 62.7%, respectively. Histological staining revealed a 71% reduction in fibrotic area, concomitant with marked downregulation of \u03b1-SMA and Collagen I expression by approximately 68% and 74%. Mechanistically, the therapeutic effects were mediated through TGF-\u03b21 gene silencing and consequent inhibition of the TGF-\u03b2/Smad pathway, resulting in attenuated HSCs activation and diminished collagen deposition. These findings indicate that TDEs@ZIF-8@TGF\u03b21siRNA represents a promising biomimetic strategy for targeted gene therapy in liver fibrosis.\n\nID: 41923477\nTitle: Orchestrating the metastatic symphony: the role of extracellular vesicles in the epithelial-mesenchymal transition and pulmonary niche formation of breast cancer.\nAbstract: The complexity of breast cancer (BC) lung metastasis lies in the capacity of tumour cells to interact efficiently with distant organs to promote colonisation, a process that involves the sophisticated coordination of inherent cellular plasticity and the remodelling of the distant microenvironment. This review emphasises the essential function of extracellular vesicles (EVs) within this communication network. Tumour-derived EVs (TEVs) not only induce epithelial-mesenchymal transition (EMT) by reprogramming breast cancer cell gene expression networks, thereby enhancing migratory and invasive capabilities, but also serve as a 'vanguard', arriving in the lungs in advance to educate stromal cells and establish a pre-metastatic niche that facilitates breast cancer progression. This review uniquely conceptualises EV-mediated EMT and niche formation as a synergistic and sequential biological continuum. We comprehensively examine the sorting mechanisms of EV molecular cargo, targeted delivery approaches, and hierarchical regulatory networks. Critically, we propose that the concurrent regulation of EMT and niche formation is likely driven by the synergistic action of distinct EV subpopulations rather than single 'multitasking' vesicles. Future investigations dissecting this heterogeneity will be pivotal for verifying this synergistic subpopulations hypothesis and establishing a theoretical basis for precise EV-based metastasis intervention strategies.\n\nID: 41912132\nTitle: Blocking CEMIP2-mediated low-molecular-weight hyaluronic acid -TGF\u03b2 signaling inhibits chemotherapy-associated lymphatic metastasis in gastric cancer.\nAbstract: Chemotherapy-associated metastasis is a major cause of failure of cancer treatment, especially neoadjuvant chemotherapy. Extracellular matrix (ECM) remodeling aways accompany with chemotherapy, but its role in chemotherapy-associated metastasis is still unclear. Here, we reveal hyaluronidase-driven degradation of hyaluronic acid (HA) as a key mechanism underlying chemotherapy-associated lymphatic metastasis in gastric cancer. We found that chemotherapy-associated lymphatic metastasis of gastric cancer occurred during neoadjuvant chemotherapy in both patients and nude mice. The proportion of HA increased significantly in ECM during chemotherapy. We also found that cell migration inducing hyaluronidase 2 (CEMIP2) is the most highly expressed hyaluronidase to degrade HA into its effective type, low molecular weight HA (LMWHA), and promoted chemotherapy-associated lymphatic metastasis of gastric cancer. Mechanistically, CEMIP2-generated LMWHA activates CD44-ATF3 signaling to transcriptionally upregulate TGF\u03b2 receptor TGFBR1, driving metastasis. CEMIP2 is highly expressed in gastric epithelium naturally. To specifically target CEMIP2 and inhibit chemotherapy-associated lymphatic metastasis of gastric cancer, we developed bioengineered RGD-conjugated exosomes mimics (EMs) for targeted delivery of CEMIP2 siRNA. This strategy potently suppressed chemotherapy-associated lymphatic metastasis in vivo. Crucially, our results position CEMIP2 as a therapeutic target to inhibit chemotherapy-associated metastasis of gastric cancer.\n\nID: 41904983\nTitle: Short-Peptide Biomaterials for Angiogenesis and Lymphangiogenesis: Advances in Tissue Engineering and Regenerative Medicine.\nAbstract: Vascular and lymphatic vessel regeneration is crucial for tissue repair and organ function restoration. However, conventional biomaterials are often constrained by poor biocompatibility and unpredictable degradation behavior. Engineered short peptides, typically comprising 2-50 amino acids, offer a promising solution for vessel regeneration through direct receptor engagement independent of exogenous cargo delivery. These peptides regulate cellular behavior through four key principles: sequence engineering, structural control, functional integration, and dynamic responsiveness. In angiogenesis, short-peptide biomaterials have demonstrated notable progress by enabling receptor-specific activation, multifunctional synergy, and the precise recognition of pathological microenvironments. Although studies on lymphatic regeneration remain limited, advances in identifying targeting sequences and mechanisms of lymphangiogenesis provide a foundation for peptide-based therapeutic strategies. Preclinically, short-peptide systems have shown therapeutic potential in cardiovascular, metabolic, and lymphatic disorders including acute myocardial infarction and diabetic complications. Furthermore, integration with artificial intelligence and 3D bioprinting is expanding the functional versatility of peptide-based biomaterials. Despite these advances, critical challenges remain, including limited predictability of sequence-structure-function relationships, stability-activity trade-offs in peptide modification, the underdevelopment of lymphangiogenic peptides, and barriers to scalable manufacturing and regulation. This review analyzes the biological basis of vascular and lymphatic regeneration, along with the design principles and mechanisms of short-peptide materials, systematically compares their regenerative strategies, highlights current limitations in bioactive peptide design and translation, and summarizes key advances and challenges to guide future development in this emerging field.\n\nID: 41903377\nTitle: Chorioallantoic membrane (CAM) of chicken embryo as an assay for biomaterial and drug testing: Current gaps and future directions.\nAbstract: The chicken embryo chorioallantoic membrane (CAM) model has emerged as a valuable tool in the fields of biomaterials, drug testing, and angiogenesis. It offers a cost-effective, ethical, and biologically relevant alternative to traditional in vivo mammalian models, aligning with the 3R principle. The CAM model is extensively used in vascular disease research, drug screening, and biomaterial biocompatibility studies, enabling a real-time analysis of angiogenic responses. Furthermore, it serves as an effective platform for evaluating tumor growth, xenografts, including photodynamic therapy (PDT), photodynamic diagnosis (PDD) applications, and blood-brain barrier permeability. Recent advancements have expanded its role in nanomedicine and regenerative medicine, demonstrating its versatility in preclinical research. Despite its advantages, challenges such as scalability and standardization still remain unresolved. This review explores CAM's vasculogenesis, angiogenesis, and lymphangiogenesis, highlighting its structural characteristics and accessibility for research applications. Furthermore, in ovo and ex ovo methodologies are discussed, detailing their advantages and limitations in different experimental contexts. Moreover, this review addresses current gaps and proposes future directions to enhance the applicability of the CAM model in biomedical sciences. Following methodological improvements and the incorporation of cutting-edge imaging and molecular approaches, the CAM assay continues advancing into a powerful alternative to the study of vascular biology, cancer, drug testing, and biomaterial interactions.\n\nID: 41803707\nTitle: Proteomic mapping of Rosa damascena nanovesicles reveals plastid mitochondrial metabolic convergence and antimicrobial peptides.\nAbstract: Rosa damascena exhibits diverse biological activities, including antimicrobial, antioxidant, anti-inflammatory, cardioprotective, neuroprotective, and skin-protective effects, largely attributed through its rich phytochemical composition. In parallel, plant-derived nanovesicles (PD-NVs) have emerged as natural nanocarriers that transport bioactive cargos capable of modulating recipient cell functions across kingdoms. In this study, Rosa damascena derived nanovesicles (RD-NVs) were isolated by ultracentrifugation and characterized by Transmission electron microscopy, nanoparticle tracking analysis, zeta potential measurement, and SDS-PAGE to confirm their vesicular nature, size distribution, and protein cargo profile. LC\u2012MS/MS-based proteomics, followed by annotation against NCBI and UniProt, and comparative BLASTP mapping to plant and human proteins, revealed 75 proteins shared with plant, Arabidopsis and human orthologs, which were further analyzed using interaction networks and hub detection together with GO and KEGG enrichment. RD-NVs (size, 40-100\u2009nm; surface charge, -25 to -40\u2009mV) carry proteins involved mainly in plastid transcription, ribosomal function, and photosynthetic electron transport in plants, whereas human mapped orthologs were enriched in oxidative phosphorylation, mitochondrial function, arginine-proline, taurine, and hypotaurine metabolism, suggesting that RD-NV hub proteins may interfere with metabolic pathways associated with obesity, insulin resistance, fatty liver, type 2 diabetes, and related inflammatory and neuroinflammatory disorders. Moreover, the peptides of the RD-NVs revealed similarities with multiple reported antimicrobial peptides therefore, might actively participate in plant and human defense system. Overall, this study reveals that the RD-NV proteome contains conserved pathways that may support metabolic and immune-related functions in cross-kingdom contexts. To validate cross-kingdom interaction in vitro, the RD-NVs were treated with the RAW264.7 macrophage which showed significant biocompatibility with a particle range of up to 8.94\u2009\u00d7\u2009108 and cellular internalization.\n\nID: 41792745\nTitle: Natural panax notoginseng-derived nanovesicles trigger multiple cell death mechanisms and reprogram chemokine signaling to impede oral squamous cell carcinoma progression.\nAbstract: Oral squamous cell carcinoma (OSCC) remains one of the most aggressive malignancies of the oral epithelium, with limited therapeutic options effectively targeting both tumor growth and metastasis. Plant-derived nanovesicles have emerged as natural, biocompatible nanomedicines with potential applications in cancer therapy. Here, we systematically screened nanovesicles from ten medicinal plants and identified Panax notoginseng-derived nanovesicles (PnNVs) as the most potent inhibitors of OSCC. PnNVs exhibited favorable safety profiles and intrinsic tumor-homing ability, selectively accumulating in orthotopic tongue tumors. In vivo, they markedly suppressed primary tumor growth and lymphatic metastasis. Mechanistically, PnNVs disrupted redox homeostasis by inhibiting the p38-MAPK/NRF2 signaling pathway, thereby inducing ferroptosis, autophagy, and PANoptosis. In addition, PnNVs impaired cancer cell migration by modulating chemokine-associated signaling pathways critical for tumor dissemination. Multi-omic analyses further revealed synergistic contributions of RNA cargos and metabolite components to their multi-target anticancer efficacy. Collectively, our findings establish PnNVs as a natural, multifunctional therapeutic candidate with dual anti-proliferative and anti-metastatic activity, providing a promising preclinical strategy for OSCC treatment.\n\nID: 41715129\nTitle: Poria cocos-derived exosome-like nanoparticles ameliorate lymphedema by reprogramming fibroblast metabolism via enhanced TCA cycle flux.\nAbstract: Lymphedema is a chronic condition characterized by impaired lymphatic drainage, leading to tissue fibrosis and functional impairment, with no effective pharmacological treatments currently available. This study investigated the therapeutic potential of Plant-Derived Exosome-like Nanoparticles (PELNs), particularly those from Poria cocos-Derived Exosome-like Nanoparticles (PcELNs), in treating lymphedema. We isolated PELNs from five botanical sources and found that PcELNs exhibited superior efficacy in alleviating lymphedema symptoms in a mouse model. Multi-omics analyses (transcriptomic, proteomic, metabolomic) revealed that PcELNs induce metabolic reprogramming in human foreskin fibroblasts (HFFs), shifting cell metabolism from glycolysis towards mitochondrial oxidative phosphorylation. This shift may be mediated through enhancing amino acid metabolism and TCA cycle flux, ultimately increasing oxidative phosphorylation. Furthermore, PcELNs reversed TGF-\u03b2-induced pro-fibrotic activation, promoting a matrix-remodeling phenotype. In vivo, PcELNs significantly ameliorated lymphedema by upregulating matrix metalloproteinases (MMP1a, MMP3) and improving mitochondrial function. Our findings demonstrate that PcELNs represent a novel and effective nanotherapeutic strategy for lymphedema by orchestrating metabolic reprogramming and inhibiting fibrosis.\n\nID: 41691624\nTitle: Insulin-like growth factor signaling regulates zebrafish lymphatic-vessel development.\nAbstract: The coordinated migration of lymphatic endothelial cells (LECs) is essential for the development of the lymphatic network. Here, we uncover the role of the insulin-like growth factor (IGF) signaling pathway in zebrafish lymphatic vessel development. We demonstrate that the medial facial lymphatic (MFL) vessel requires cartilage of the hyoid arch for development and identify pregnancy-associated plasma protein A2 (pappa2) as a possible candidate for mediating the cartilage-lymphatic interaction. Pappa2 encodes a secreted metalloprotease that cleaves IGF-binding proteins (IGFBPs; Igfbp3 and Igfbp5b) also expressed near the hyoid cartilage. Overexpression of IGFs and inhibition of IGFBPs enhance MFL growth, while pappa2 knockdown, overexpression of Igfbp3/Igfbp5b, or inhibition of IGF1R inhibit MFL growth. We show that Igf signaling has a cell-autonomous role in zebrafish lymphatic development and that induced pluripotent stem cell (iPSC)-derived human LECs express IGF1R and migrate in response to IGF2. Our data highlight the importance of the IGF signaling pathway in lymphatic-vessel development.\n\nID: 41616889\nTitle: Engineered acid-regulating liposomal nanovesicles for synergistic photodynamic pyroptosis and immunotherapy.\nAbstract: Gasdermin-mediated pyroptosis has emerged as a promising mechanism in cancer immunotherapy, however, its efficacy is often limited by inefficient activation within the immunosuppressive tumor environment. Herein, we generated an acid-regulating biomimetic liposomal nanovesicle (L-P-Cn-U) for the co-delivery of a photosensitizer prodrug (P-Cn) and a carbonic anhydrase IX (CAIX) inhibitor (U-104). By conducting efficacy screening of various P-Cn prodrugs within the L-P-Cn-U system, we identified L-P-C16-U with identical lipid tail structures, as the optimal candidate due to its strong colloidal stability and reactive oxygen species (ROS) generation efficiency. Our cellular and murine model studies demonstrated that L-P-Cn-U-mediated pyroptosis and immunogenic cell death could convert immunologically cold tumors into hot tumors, thereby enhancing antitumor immunity and concurrently inhibiting tumor cell migration. Mechanistic investigation revealed that the acid-triggered U-104 release from L-P-Cn-U augmented intracellular acidity through CAIX inhibition, which subsequently attenuated PI3K-Akt/mTOR signaling. This result enhances O2-dependent ROS production and establishes a negative feedback loop for CAIX expression. Collectively, our findings provide a combinatorial strategy that integrates pyroptosis-focused therapy with metabolic regulation, offering a broadly applicable conception to augment cancer immunotherapy. STATEMENT OF SIGNIFICANCE: Herein, we report the rational design and synthesis of a new class of biomimetic liposome by integrating chemically engineered pH-responsive lipids (L-pH) with lipid-like photosensitizer prodrugs (P-Cn). Characterization studies demonstrated an optimal construct (L-P-C16) with identical lipid tails, showing robust stability and reactive oxygen species production. This optimized nanovesicle was subsequently co-loaded with the carbonic anhydrase inhibitor U-104. The resulting L-P-C16-U system was adequately investigated and shown to effectively synergize photodynamic therapy and immunotherapy. Our work provides new insights into liposome engineering strategies for combination tumor therapy.\n\nID: 41616517\nTitle: Therapeutic potential of exosomes in malignancies: From drug delivery to clinical application.\nAbstract: Cancer remains one of the most pressing global health challenges, with conventional treatments such as chemotherapy and radiotherapy constrained by modest efficacy and severe long\u2011term adverse effects. Exosomes-nano\u2011sized extracellular vesicles (30-150\u202fnm) secreted by diverse cell types-have emerged as promising candidates for cancer diagnosis and therapy due to their inherent biocompatibility, low immunogenicity, and ability to cross biological barriers. A comprehensive review of recent literature was conducted to summarize advancements in exosome biology, isolation techniques, and engineering strategies relevant to cancer nanomedicine. Particular emphasis was placed on ESCRT (Endosomal Sorting Complex Required for Transport) dependent biogenesis mechanisms, molecular cargo profiling, and applications in targeted drug delivery. Tumor\u2011derived exosomes play multifaceted roles in cancer progression, including modulation of the tumor microenvironment, facilitation of metastasis, and induction of therapeutic resistance. Their molecular cargo-comprising proteins, lipids, and nucleic acids-serves as a dynamic reflection of the physiological or pathological status of the tumor cells. Technological innovations in exosome isolation, surface modification, and therapeutic payload loading have markedly improved targeted delivery and preclinical treatment outcomes. Notably, drug\u2011loaded exosomes demonstrate the ability to circumvent multidrug resistance. Exosomes hold substantial promise for precision oncology through enhanced drug delivery and diagnostic applications. However, clinical translation requires standardized manufacturing, comprehensive safety profiling, and scalable production methods to address current limitations. Emerging strategies such as exosome mimetics and AI\u2011assisted production optimization poised to address these limitations, guiding the development of personalized, efficient, and targeted cancer treatments.\n\nID: 41607233\nTitle: Programmable G-Quadruplex@DNA Nano-Highway Network Platform Enables One-Pot Electrochemical Detection of Exosomes for Breast Cancer Lymph Node Metastasis Evaluation.\nAbstract: Exosomes are promising biomarkers for early tumor diagnosis and metastasis assessment. However, current methods are unsuitable for routine use because of low accuracy and complexity. In this study, we developed a universal detection platform based on a G-quadruplex@DNA nano-highway network (G4@DNA-NHWN). This platform used aptamer-triggered hybridization chain reaction and streptavidin-biotin crosslinking to construct a protein-scaffolded DNA nanostructure enriched with split G4 via a one-pot method at room temperature, enabling sensitive and rapid detection of exosomes. Vimentin, a protein overexpressed in exosomes during the progression and metastasis of breast cancer, was selected as an example. Vimentin binding to the aptamer in G4@DNA-NHWN induces structural disassembly, preventing the split G4 from forming G4-Pb2+ complexes with Pb2+, thereby increasing the free Pb2+. Electrochemical (EC) detection enabled the homogeneous quantification of vimentin by directly distinguishing the EC signal differences between the inert G4-Pb2+ complex and Pb2+. The results demonstrated that this system achieved exosomes detection with a sensitivity as 30 particles/mL within 1 h, and exhibited excellent selectivity. Validation across 42 clinical samples demonstrated a concordance rate of >\u00a090% with the clinical diagnoses. As a DNA-functionalized nanomaterial platform, this system holds the promise of approaches in targeted drug delivery and other biomedical applications beyond biosensing.\n\nID: 41540479\nTitle: Running exercise mitigates amyloidosis in 5xFAD mice by improving the structure and function of the meningeal lymphatic system.\nAbstract: BACKGROUND: Alzheimer\u2019s disease (AD) progression is closely linked to the accumulation of amyloid-[Formula: see text] (A[Formula: see text]), with impaired clearance mechanisms playing a key role. The meningeal lymphatic (mLym) system, which drains cerebrospinal fluid (CSF) and waste from the brain to peripheral lymph nodes, has emerged as a critical pathway for A[Formula: see text] removal. While physical exercise is known to improve cognitive function and reduce AD risk, its effect on the mLym system and downstream AD pathology have not been fully elucidated. METHODS: Three-month-old 5xFAD mice underwent a 3-month wheel-running exercise regimen. The function of the mLym system was assessed before and after exercise using high-frequency ultrasound imaging with nanoparticle tracers to monitor CSF drainage to deep cervical lymph nodes. The study evaluated changes in mLym vessel structure, A[Formula: see text] deposition, and cognitive performance. Additionally, the effects of serum and extracellular vesicles (EVs) from exercised rats on the expression of lymphatic vessel-related genes (LYVE-1, VEGFR3, and VEGF-C) were examined in lymphatic endothelial and microglial cell lines. RESULTS: Compared to 3-month-old 5xFAD mice and age-matched wild-type controls, 6-month-old 5xFAD mice displayed progressive decline in mLym function, reduced vessel integrity, and increased amyloid plaque burden, accompanied by impaired learning and memory. These changes were associated with decreased expression of LYVE-1 and VEGFR3 in the meninges and VEGF-C in the brain. Exercise intervention reversed these deficits, restoring mLym function and vessel structure, enhancing A[Formula: see text] clearance, and improving cognitive performance. Surgical ligation of mLym vessels accelerated amyloid accumulation and removed the exercise-induced benefits, underscoring the system\u2019s importance in A[Formula: see text] removal. In vitro, A[Formula: see text] oligomers suppressed VEGFR3 and VEGF-C expression, while serum and EVs from exercised rats counteracted this effect. Proteomic analysis of EVs from exercised animals revealed upregulation of CD9, suggesting a link to VEGFR3 signaling. CONCLUSIONS: This study demonstrates that A[Formula: see text] oligomers impair mLym function, exacerbating amyloid pathology. Exercise preserves the structure and function of the mLym system, promoting A[Formula: see text] clearance and mitigating AD progression. These findings highlight the therapeutic potential of targeting the meningeal lymphatic system to slow or prevent AD.\n\nID: 41488867\nTitle: Plant Exosome-Loaded Intelligent Hydrogels for Osteoporotic Bone Regeneration: Mechanisms and Applications.\nAbstract: Osteoporotic bone defects (OBDs), characterized by disrupted bone metabolic homeostasis, insufficient vascularization, and a persistent inflammatory microenvironment, exhibit poor intrinsic regenerative capacity and remain a pressing clinical challenge in orthopedic practice. Plant-derived exosomes (P-Exos)-a unique class of bioactive nanovesicles enriched in regulatory miRNAs, lipids, proteins, and phytoactive metabolites-have emerged as promising natural modulators capable of enhancing osteogenic differentiation, suppressing excessive osteoclast activity, promoting angiogenesis, and mitigating inflammation. Intelligent hydrogels, with their tunable physicochemical properties, high biocompatibility, and extracellular matrix-mimicking architecture, provide a versatile platform for stabilizing P-Exos and achieving controlled, spatiotemporally regulated release. This review systematically summarizes the biological characteristics of P-Exos and elucidates their roles in orchestrating osteoporotic bone repair. Particular emphasis is placed on the design principles of environmentally responsive hydrogels-including thermosensitive, pH-responsive, photocrosslinkable, and other stimuli-adaptive systems-and their capacity to efficiently encapsulate and precisely deliver P-Exos. Furthermore, the synergistic effects of P-Exos-hydrogel composites in modulating the osteoimmune microenvironment, reinforcing angiogenesis-osteogenesis coupling, and accelerating functional bone regeneration are highlighted. Finally, the review addresses the major challenges that impede clinical translation, including the lack of standardized large-scale production of P-Exos, incomplete pharmacokinetic profiles under hydrogel-mediated release, and limited long-term in vivo data. Overall, this work provides a comprehensive conceptual framework and technical perspective to guide the development of safe, efficient, and precision-engineered therapeutic strategies for the treatment of osteoporotic bone defects.\n\nID: 41456527\nTitle: Cerebralcare Granule\u00ae restores intracranial lymphatic drainage system to support proactive brain health in Alzheimer's disease models.\nAbstract: Impairment of the intracranial lymphatic drainage system significantly contributes to Alzheimer's disease (AD) by facilitating the accumulation of neurotoxic amyloid-\u03b2 (A\u03b2) and tau proteins. Restoring lymphatic function offers a promising preventive strategy against early-stage AD pathology. This study aimed to evaluate the effects and mechanisms of Cerebralcare Granule\u00ae (CG), a traditional Chinese medicine formula, on cognitive impairment and pathological markers in AD mouse models by modulating intracranial lymphatic clearance pathways. Six-month-old APP/PS1 transgenic mice and wild-type controls received oral administration of CG or donepezil for two months. Behavioral assessments included the Morris water maze, open field, Y-maze, novel object recognition, and passive avoidance tests. Immunohistochemistry, immunofluorescence, and Western blot analyses were used to assess A\u03b2 deposition, glymphatic clearance, astrocytic aquaporin-4 (AQP4) polarization, meningeal lymphangiogenesis, and blood-brain barrier integrity. Tracer-based in vivo imaging confirmed improved CSF influx and efflux dynamics. Brain-penetrant compounds of CG were identified using UPLC-MS/MS, MALDI-TOF-MS imaging, and network pharmacology. CG treatment significantly improved cognitive performance, reduced A\u03b2 burden, enhanced glymphatic transport, and promoted meningeal lymphatic drainage in APP/PS1 mice. CG restored perivascular AQP4 polarization, improved cerebrospinal fluid-interstitial fluid exchange, facilitated waste removal to cervical lymph nodes, and protected the integrity of the blood-brain barrier. Major brain-penetrant compounds-paeoniflorin, rhynchophylline, and ethyl gallate-were found to target lymphatic signaling pathways (AQP4, VEGFC, VEGFR3, PROX1) effectively. CG exerts protective effects against cognitive impairment and AD pathology by reinforcing the structural and functional integrity of the intracranial lymphatic drainage system, highlighting a novel therapeutic avenue for proactive brain health management in early-stage AD.\n\nID: 41310078\nTitle: Plasma-derived exosomal tRF-3004a as a diagnostic biomarker for colorectal cancer.\nAbstract: Transfer RNA-derived small RNAs (tsRNAs) play crucial regulatory roles in tumour biology; however, their potential as biomarkers for colorectal cancer (CRC) remains underexplored. Plasma samples from 123 patients with CRC and 79 healthy controls (HCs) were collected for this study. Exosomes were extracted from plasma, validated, and tRF-3004a levels were detected using quantitative real-time polymerase chain reaction (qRT-PCR). The correlation between plasma-derived exosomal tRF-3004a expression levels and clinicopathological parameters was analysed using the chi-square test. Receiver operating characteristic (ROC) curve analysis was performed to evaluate the diagnostic performance of plasma-derived exosomal tRF-3004a. The results showed that compared with HCs, plasma-derived exosomal tRF-3004a was significantly elevated in patients with CRC and decreased after surgery. Moreover, high tRF-3004a expression was significantly associated with lymph node metastasis, tumour node-metastasis staging, carcinoembryonic antigen (CEA) levels, and nerve/vascular invasion in patients with CRC. ROC analysis revealed that plasma-derived exosomal tRF-3004a demonstrated promising diagnostic utility for CRC, with an area under the curve (AUC) of 0.819 (sensitivity, 0.691; specificity, 0.861). The combination of CEA and carbohydrate antigen 19\u2009-\u20099 (CA19-9) levels increased the AUC to 0.867. The results of this study demonstrate that plasma-derived exosomal tRF-3004a may serve as a novel diagnostic biomarker for CRC.\n\nID: 41271059\nTitle: Supramolecular complex of a gemini amphiphilic pseudopeptide and p-coumaric acid as a pH- responsive drug delivery system for brain cancer therapy.\nAbstract: Supramolecular complex based on Gemini amphiphilic pseudopeptides (GAP 5a) and para coumaric acid (p-CA) was designed, synthesized and formulated into nanovesicles as drug delivery system for brain cancer therapy. Molecular docking and molecular dynamics simulations revealed strong GAP 5a/p-CA interactions and favorable translocation across lipid bilayers. GAP 5a/p-CA nanovesicles exhibited spherical morphology, a negative surface charge and an average particle size of 306.5\u00a0nm, enabling efficient tumor targeting. Notably, GAP 5a nanovesicles achieved high drug entrapment efficiency (90.7\u00a0%) and pH-responsive release, with faster drug liberation under acidic conditions mimicking the tumor microenvironment. Additionally, in vitro release studies demonstrated a more controlled release of the drug from nanovesicles compared to drug solution. Loading p-CA on GAP 5a nanovesicles resulted in a two-fold increase in the drug's cytotoxicity on Glioma GL261 cancer cells, from IC50 936\u00a0\u03bcg/mL to 451\u00a0\u03bcg/mL, consistent with formulation-dependent effects playing a key role. p-CA and GAP 5a scored high IC50 values on VERO cells implying good safety profile of the prepared novel system. Nonetheless, the in-vitro IC\u2085\u2080 values lie in the high \u03bcg/mL range, limiting immediate translational prospects. Accordingly, these findings pave the way for further optimization of GAP nanovesicles as promising carriers of polyphenol model p-CA towards brain cancer cells.\n\nID: 41196511\nTitle: Surface decoration of solid lipid nanoparticles with cyclic RGD peptides for precision therapy in high-risk neuroblastoma.\nAbstract: High-risk neuroblastoma poses significant therapeutic challenges due to tumor heterogeneity, drug resistance, and systemic toxicity associated with conventional chemotherapies. To overcome these limitations, we developed cyclic RGD-decorated solid lipid nanoparticles for integrin-targeted delivery of etoposide, aiming to enhance tumor selectivity and therapeutic efficacy. SLNs were prepared using hot homogenization and ultrasonication, with cyclic RGD peptides conjugated to the surface via non-covalent and covalent strategies. Among three conjugation approaches evaluated, maleimide-based functionalization was selected for its reproducibility, stability, and high coupling efficiency. RGD-functionalized SLNs were physicochemically characterized and assessed for integrin-mediated uptake, cytotoxicity, cell cycle effects, and apoptosis induction in SH-SY5Y (integrin-high) and SK-N-BE(2) (integrin-low) NB cell lines. RGD-SLNs demonstrated efficient peptide conjugation while maintaining colloidal stability and drug loading. Flow cytometry confirmed enhanced uptake in \u03b1v\u03b23 integrin-expressing SH-SY5Y cells, with moderate uptake in SK-N-BE(2) cells. ETP encapsulation within SLNs significantly improved its cytotoxic profile, with RGD functionalization further reducing IC50 values and promoting apoptosis. These findings establish RGD-functionalized SLNs as a promising integrin-targeted platform for ETP delivery in NB. To our knowledge, this is the first report of this approach using SLNs for NB, offering a novel strategy for translational nanomedicine.\n\nID: 41190394\nTitle: Exosomes in cancer metabolism and drug resistance: A review.\nAbstract: The transfer of molecular cargo in exosomes plays a crucial role in cancer progression, influencing metabolic processes, angiogenesis, immune interactions, and invasive capabilities. This review synthesizes current evidence on how exosomes modulate tumor metabolism and drive drug resistance, and outlines therapeutic opportunities. We searched PubMed, Scopus, Web of Science, and Google Scholar for English-language studies using terms related to exosomes/extracellular vesicles, glycolysis, oxidative phosphorylation (OXPHOS), lipid metabolism, and drug resistance/chemoresistance, and integrated the literature qualitatively. Evidence indicates that exosomes reprogram tumor and stromal metabolism by delivering enzymes and non-coding RNAs that boost glycolysis and dampen OXPHOS, activate cancer-associated fibroblasts and extracellular matrix (ECM) remodeling, and modulate ferroptosis. They stimulate angiogenesis (e.g., via vascular endothelial growth factor (VEGF)/Wnt pathways) and promote immune escape through programmed death-ligand 1 (PD-L1), transforming growth factor beta (TGF-\u03b2), and macrophage reprogramming. Exosomal integrins and proteases contribute to epithelial-mesenchymal transition (EMT), organotropism, and pre-metastatic niche formation. Critically, exosomes propagate chemoresistance by exporting drugs and spreading determinants-including P-gp/BCRP/MRP-1, anti-apoptotic proteins, and regulatory RNAs-to previously sensitive cells; adipose-derived vesicles and lipid cargos further reinforce metabolic plasticity and therapy resistance. Given their stability, nanoscale dimensions, and ability to cross the blood-brain barrier, exosomes are promising vectors for targeted delivery; engineered vesicles can enhance chemotherapy responsiveness and counteract resistance, particularly alongside immunotherapy. In summary, interventions that disrupt exosome biogenesis, cargo loading, or uptake-paired with engineered exosomes for precision delivery-could mitigate drug resistance, metastasis, and immune evasion and advance more effective cancer treatment.\n\nID: 41185659\nTitle: Prox1 Is Linked to Metastasis and Poor Prognosis by Promoting Lymphangiogenesis in Melanoma.\nAbstract: The purpose of this study is to investigate the role of Prox1 in the progression of cutaneous melanoma (CMM) and its relationship with lymphatic metastasis. By analyzing the data from the Cancer Genome Atlas (TCGA), we found that the expression of Prox1 and LYVE1 was significantly upregulated in the metastatic melanoma group. Additionally, elevated levels of Prox1 were associated with shorter survival times. Correlation analysis demonstrated a significant relationship between Prox1 and markers associated with lymphangiogenesis, including LYVE1, FLT4, FOXC2, and ANGPT2. A clinical study involving 32 cases of CMM was conducted to analyze Prox1 expression and its relationship with lymphangiogenesis and clinicopathological characteristics. Research revealed that Prox1 was expressed significantly higher in patients with lymph node (LN) metastasis and in those classified as stage 3C-4. Additionally, the density of lymphatic vessels(LVD) in the LN metastasis group and the stage 3C-4 group was markedly higher than in the group without lymph node metastasis and in the stage 0-3B group. Furthermore, Breslow thickness was found to correlate with both Prox1 expression and LVD. Prox1-positive expression was associated with increased LVD. Further investigation was conducted on the role of Prox1 in the CMM cell line A375 and its derived exosomes. Exosomes were collected from CMMnc and CMMshProx1 to verify the changes in Prox1 expression, respectively. It was observed that the proliferation, migration, and tube formation abilities of human lymphatic endothelial cells(HLECs) diminished with the downregulation of Prox1. Additionally, VEGFR3 activation was reduced in HLECs following the reduction of Prox1. Prox1\u00a0played an important role in promoting cell proliferation, migration, and lymphangiogenesis, which is related to tumor metastasis and poor prognosis. These results indicated the potential importance of Prox1 as a biomarker, which is expected to lead to the development of a new insight for anti-tumor therapy.\n\nID: 41169569\nTitle: Stoichiometry-Controlled Structural Transformation of Diphenylalanine Nanoassemblies through Coassembly with Charged Dipeptides.\nAbstract: Peptide self-assembly produces a wide range of well-structured nanostructures, offering significant potential for biomedical and nanotechnological applications. However, controlling the morphologies of these assemblies is considerably challenging due to their intricate polymorphisms and complex responsiveness to environmental changes. In this study, we present a stoichiometry-controlled strategy to finely tune the morphology of supramolecular nanostructures by coassembling diphenylalanine (FF) with charged aromatic dipeptides. Diverse nanostructures including one-dimensional nanotubes, two-dimensional planar sheets, and three-dimensional nanovesicles are obtained by varying the ratio of two peptide building blocks. These structures are predicted by coarse-grained simulations, subsequently validated for stability by all-atom simulations, and further confirmed by experiments. Notably, planar sheets, rarely seen in FF self-assembly, emerge frequently when coassembling FF with high ratios of charged dipeptides. Interaction analysis reveals that the formation of these diverse nanostructures is driven by aromatic stacking and modulated by the strength of electrostatic repulsion. Remarkably, pH-responsive environments induce transformations between nanovesicles and planar sheets, underscoring their potential for biomedical applications. This study underscores the potential of a stoichiometry-controlled strategy to design multidimensional nanostructures with tunable morphologies, offering significant promise for nanomedicine applications, such as precision-targeted drug delivery systems.\n\nID: 41105786\nTitle: Targeting RRM2 with dual-modal theranostic smart nanoresponder overcomes osimertinib resistance and triggers immune remodeling in NSCLC.\nAbstract: Osimertinib (Osi) resistance limits its efficacy in EGFR-mutant non-small cell lung cancer (NSCLC). Here, we developed a pH-responsive cationic nanovesicle (124I/Cy5.5-sO@FCLs), equipped with dual-modal positron emission tomography (PET) and fluorescence imaging capabilities, to enable dynamic monitoring of the role of ribonucleotide reductase M2 subunit (RRM2) disruption in overcoming Osi resistance and enhance targeted anticancer efficacy in NSCLC. RRM2 was identified as a critical driver of poor prognosis and Osi resistance in NSCLC. The 124I/Cy5.5-sO@FCLs enabled real-time tracking of tumor targeting and biodistribution, and CRISPR-Cas9-mediated RRM2 disruption efficiently reversed Osi resistance and potentiated synergistic anticancer effects, which was attributed to counteracting TGF-\u03b2/Smad2/3-mediated epithelial-mesenchymal transition (EMT) and amplifying cGAS/STING-induced ferroptosis. Furthermore, the nanovesicles triggered STING-dependent immunogenic cell death (ICD), stimulating tumor infiltration of dendritic cells (DCs) and T cells; combination with anti-PD-L1 therapy augmented NSCLC regression. Collectively, 124I/Cy5.5-sO@FCLs integrate gene editing with targeted therapies while enabling dynamic, quantitative monitoring, providing an approach for precision-targeted treatment in Osi-resistant NSCLC.\n\nID: 40955653\nTitle: Targeted Cascade Therapy with Multifunctional Nanovesicles Engineered from Synergistic Antibacterial Agents for Precision Treatment of Multidrug-Resistant Infections and Biofilms.\nAbstract: Multidrug-resistant (MDR) Staphylococcus aureus (S. aureus), classified as a high-priority tier II pathogen, poses a glowing threat to global health. Single-mode antibacterial approaches often fall short of achieving optimal effects, necessitating the development of combination therapies. To address these challenges, pH-responsive antibacterial nanovesicles, termed DAClLy, are developed by integrating targeting ligand and multiple antimicrobial agents with complementary modes of action to target MDR bacteria with enhanced efficacy while minimizing adverse effects. DAClLy are engineered through the complexation of sulfonium-ion-bearing antibacterial polypeptoids, and primary amine-containing polypeptoids modified with 2,3-dimethyl maleic anhydride, encapsulating lysostaphin, a bacteriolytic enzyme. Upon reaching the acidic microenvironment of bacterial infections, the DAClLy vesicles disassemble, releasing their antimicrobial components. The released lysostaphin degrades bacterial cell walls, while the polypeptoids synergistically disrupt bacterial membranes, resulting in a multi-action bactericidal effect. This synergistic mechanism demonstrates remarkable efficacy against MDR S. aureus, including its resilient biofilm formations. In vivo studies have shown that the DAClLy vesicles exhibit potent antibacterial activity against MDR S. aureus-induced skin and lung infections. The nanovesicles effectively penetrate the lung mucus barrier, addressing both surface-level and deep-tissue infections. By integrating multiple strategies, DAClLy offers a promising therapeutic strategy to combat MDR pathogens across diverse tissue contexts.\n\nID: 40944610\nTitle: Injectable Hyaluronic Acid Hydrogel Integrated with Hybrid Nanovesicles for Synergistic Enhancement of Transdermal Drug Delivery.\nAbstract: Plant-derived nanovesicles offer promising potential for transdermal drug delivery due to their inherent biocompatibility and low immunogenicity, yet face limitations in drug loading, structural stability, and functional optimization. This study presents a versatile Hybrid-Gel platform that integrates CoQ10-loaded hybrid vesicles with an injectable, pH-responsive hydrogel to enhance localized drug delivery. High-purity nanovesicles are isolated using an optimized ultracentrifugation (UC) and size-exclusion chromatography (SEC) method, then hybridized with liposomes to improve encapsulation and skin penetration. To further optimize localized delivery performance, an injectable binary hydrogel system is then introduced. This hydrogel, formed via Schiff base crosslinking between hyperbranched polyethylene glycol and aldehyde-modified hyaluronic acid (A-HA), exhibits mild gelation conditions, excellent injectability, and strong tissue adhesion. The hydrogel effectively encapsulates hybrid nanovesicles, ensuring enhanced stability, ease of administration, and controlled, pH-responsive release. As a proof of concept, an in vitro permeation test with porcine skin model demonstrates that the hydrogel significantly improves CoQ10 penetration, achieving a more than fourfold increase in transdermal efficiency compared to free CoQ10, suggesting superior bioavailability. This synergistic approach, combining hybrid nanovesicle-mediated drug transport with a dynamic hydrogel matrix, offers a robust and versatile platform for localized transdermal therapy, with potential applications in precision medicine, regenerative treatments, and chronic disease management.\n\nID: 42654029\nTitle: Ion- and pH-Responsive In Situ Gel Incorporating Luteolin-Loaded Nanostructured Lipid Carriers Enhances Ocular Bioavailability and Anti-Angiogenic Efficacy for Corneal Neovascularization.\nAbstract: Background/Objectives: Corneal neovascularization (CNV) is a leading cause of vision loss, but current treatments are limited by poor ocular drug penetration and rapid tear clearance. Luteolin (LUT) is a poorly water-soluble natural anti-angiogenic agent. To address this limitation, we develop an ion- and pH-responsive in situ gel system (LUT-NLC-ISG) by incorporating LUT-loaded nanostructured lipid carriers (LUT-NLC) into a gellan gum/Carbopol matrix, aiming to enhance ocular bioavailability and therapeutic efficacy against CNV. Methods: LUT-NLC-ISG was optimized using a central composite design-response surface methodology (CCD-RSM) and characterized by physicochemical properties (particle size, viscosity, gelation behavior). Ocular pharmacokinetics and biodistribution were evaluated in rabbits after a single topical administration. Biocompatibility was assessed via Hen's egg test-chorioallantoic membrane assay (HET-CAM), Draize tests, and cytotoxicity studies. Therapeutic efficacy and mechanism were investigated in a murine model of alkali burn-induced CNV. Results: The optimized LUT-NLC-ISG had a particle size of 25.27 \u00b1 0.23 nm and exhibited a 45-fold viscosity increase upon simulated tear fluid (STF) exposure. In rabbits, LUT-NLC-ISG significantly increased the bioavailability of LUT in ocular tissues compared with LUT-NLC alone, with 2.57-, 1.83-, and 10.59-fold higher area under the concentration-time curve (AUC) in the cornea, conjunctiva, and tears, respectively and exhibited excellent ocular biocompatibility. In the CNV mouse model, 0.1% (w/v) LUT-NLC-ISG effectively inhibited corneal neovascularization, comparable to 0.025% dexamethasone, and downregulated VEGF-A and MMP-9 expression. Conclusions: LUT-NLC-ISG synergistically combines NLC technology and dual-sensitive in situ gelation to significantly improve LUT ocular bioavailability, offering a promising non-invasive candidate for CNV management.\n\nID: 42650187\nTitle: Curcumin-Loaded Milk-Derived Exosomes Improve the Developmental Competence of Yak Oocytes by Regulating Mitophagy.\nAbstract: Yaks are a distinctive livestock species native to the Qinghai-Tibet Plateau. However, the low in vitro maturation rate of their oocytes significantly limits the efficiency of assisted reproductive technologies. Curcumin (CUR), known for its bioactive functions, including antioxidant and anti-inflammatory properties, suffers from low water solubility and bioavailability, which restricts its practical applications. This study aimed to develop a curcumin-loaded bovine milk-derived exosome nanodelivery system (CUR-mEXOs) and investigate its effects on the in vitro maturation of yak oocytes and the embryonic development of parthenogenetic embryos, leveraging its natural biocompatibility and targeted delivery properties. The results indicated that the isolated mEXOs exhibited typical exosome morphology and nanoscale particle size characteristics and were effectively internalized by the oocytes. During in vitro maturation, treatment with 10 \u03bcM CUR produced optimal outcomes. Compared to free CUR, CUR-mEXOs significantly enhanced the cumulus expansion index and the rate of first polar body expulsion, reduced intracellular ROS accumulation and mitochondrial superoxide levels, and improved mitochondrial function and spindle morphology, while simultaneously upregulating the expression of factors related to mitochondrial autophagy and oocyte maturation. Following intervention with the mitochondrial autophagy inhibitor CsA, the promotive effect of CUR-mEXOs was significantly diminished, leading to increased blastocyst apoptosis and a decrease in the total cell count. In summary, CUR-mEXOs can enhance the quality of in vitro maturation of yak oocytes and their embryonic developmental capacity following parthenogenesis by regulating mitochondrial autophagy. This study established an experimental foundation for optimizing the in vitro maturation system of yak oocytes and developing strategies for the delivery of natural bioactive substances. Additionally, this study provides a theoretical basis for enhancing the efficiency of assisted reproductive technologies in yaks.\n\nID: 42645768\nTitle: Curcumin-loaded PEGylated Magnetic Iron Oxide Nanoparticles: a Biogenic Platform for Targeted and Controlled Drug Release.\nAbstract: The development of environmentally sustainable and targeted nanocarriers is crucial for improving the therapeutic efficacy of anticancer agents while reducing systemic toxicity. Here we successfully synthesized curcumin (CUR) loaded polyethylene glycol (PEG) functionalized magnetic iron oxide nanoparticles (Fe3O4@PEG-CUR-NPs) by a green biogenic approach using Hibiscus rosa-sinensis flower extract and evaluated as a multifunctional platform for controlled drug delivery and cancer therapy. UV-Vis, FTIR, PXRD, SEM, TEM, DLS, TGA and VSM characterizations have been performed comprehensively to confirm the successful fabrication of crystalline, spherical nanoparticles with average size of 10-15\u00a0nm, excellent colloidal stability (zeta potential\u2009-\u200931.5\u00a0mV) and retained magnetic responsiveness with saturation magnetization of 28.30\u00a0emu/g. The nanocarrier showed significant pH-responsive drug release, with 90.55% cumulative CUR release under acidic conditions (pH 4.5) compared to 44.5% at physiological pH (7.4), indicating its possibility for tumor-targeted delivery. Release kinetic studies revealed that the drug release was mainly diffusion-controlled and followed a non-Fickian transport mechanism. Besides, Fe3O4@PEG-CUR-NPs showed good anti-inflammatory effect with IC50 value of 25.10\u00a0\u03bcg/mL, which was significantly better than diclofenac (IC50\u2009=\u200982.20\u00a0\u03bcg/mL). In vitro cytotoxicity assays showed potent and dose dependent anticancer activity against A549, MDA-MB-231 and MCF-7 cell lines with IC50 values of 50.2, 10.5 and 6.7\u00a0\u03bcg/mL respectively, indicating an increased susceptibility of breast cancer cells. The synergistic combination of green synthesis, magnetic targeting capability, pH-triggered drug release, and superior anticancer efficacy highlights Fe3O4@PEG-CUR-NPs as a promising nanotherapeutic platform for precision cancer treatment and advanced biomedical applications.\n\nID: 42644963\nTitle: Efficient Preparation of pH-Sensitive Core-Shell Drug-Loaded Hydrogel Microcapsules and Their Application in Ulcerative Colitis Treatment.\nAbstract: Conventional microsphere drug carriers for ulcerative colitis (UC) face challenges such as limited residence time, variable drug release, and an increased risk of systemic exposure and side effects. In this study, pH-sensitive, core-shell hydrogel microcapsules were designed and fabricated using a BUCHI B-390 microsphere preparation device via electrostatic interactions and hydrogen bonds. Olsalazine sodium was encapsulated in the microcapsules, allowing for pH-responsive drug release in colon tissue for UC treatment in mice. XRD studies demonstrated the amorphous state of the drug in the formulation. The preparation of SCO microcapsules was optimized based on the drug encapsulation efficiency and the drug loading capacity, with the S2C1O microcapsule having the highest drug encapsulation efficiency (59.2%) and drug loading capacity (21.3%), and the production yield was approximately 62.5%. The degradation experiment results indicated that the alginate/CMCS hydrogel shell has anti-resistant and colon-targeted properties, with minimal drug leakage under acidic conditions (0.1% release at 2 h, pH 1.2) and rapid, controlled release at colonic pH (7.4) (cumulative release of 68.7% at 12 h), protecting the drug from gastric degradation. An in vivo experiment suggested that treatment with these microcapsules in UC mice significantly reduced inflammatory markers (NF-\u03baB p65 was reduced by 18.8% relative to the free drug group) and histological damage in UC models relative to free drug administration. The improved therapeutic efficacy is linked to precise localization in inflamed tissue, reducing systemic exposure and off-target effects. Overall, in vitro and in vivo studies demonstrated that this microcapsule system provides a promising alternative to existing UC drug delivery systems.\n\nID: 42636924\nTitle: Antibodies and aptamers as affinity ligands for exosome isolation, detection, and targeted delivery: A review.\nAbstract: Exosomes, key mediators of intercellular communication, are emerging as promising tools for disease diagnosis and therapy. Realizing this potential depends on technologies that can isolate, detect, and deliver exosomes with high specificity and efficiency. Affinity-based strategies that exploit the molecular recognition of antibodies and aptamers are central to this effort. In this review, we analyze how these ligands are advancing exosome research. We first examine isolation methods, benchmarking affinity capture against conventional techniques and weighing trade-offs among yield, purity, and vesicle integrity. We next explore detection technologies, in which antibody- and aptamer-based biosensors enable ultrasensitive, multiplexed, and point-of-care assays. Finally, we discuss the therapeutic frontier, where ligand-mediated surface functionalization creates targeted delivery vehicles. In preclinical models, engineered exosomes can traverse biological barriers and deliver multimodal payloads, indicating potential therapeutic avenues for cancer as well as neurodegenerative and metabolic disorders. Taken together, we highlight the synergy between affinity ligands and exosome science and outline key challenges for clinical translation.\n\nID: 42635933\nTitle: miR-486-5p suppresses autophagy in hepatocellular carcinoma via activation of the AKT/mTOR signalling pathway.\nAbstract: Autophagy is controlled by a complex signalling network and is closely linked to the initiation and progression of hepatocellular carcinoma (HCC). However, how microRNAs (miRNAs) regulate autophagy in HCC remains incompletely understood. In this study, we identified microRNA-486-5p (miR-486-5p) as a tumour-associated microRNA that is enriched in circulating exosomes derived from patients with HCC. Elevated miR-486-5p promoted proliferation and suppressed apoptosis in HCC cell lines under stress conditions. Mechanistically, miR-486-5p directly targets the 3' untranslated region of the phosphatase and tensin homologue (PTEN) gene, thereby decreasing the production of the PTEN protein and consequently leading to the activation of the protein kinase B (AKT)/mammalian target of rapamycin (mTOR) signalling pathway. This phenomenon was accompanied by the inhibitory phosphorylation of unc-51\u00a0like autophagy-activating kinase 1 (ULK1), which resulted in impaired autophagy. The pharmacological inhibition of AKT or mTOR led to the restoration of autophagy and the attenuation of miR-486-5p-driven growth and survival advantages. Furthermore, the transcription factor MYB was found to bind the promoter of ankyrin-1 (ANK1), the host gene of miR-486-5p, and to drive its expression. In an orthotopic liver tumour model, the liver-targeted delivery of miR-486-5p accelerated tumour expansion, an effect that was reversed by AKT or mTOR blockade. Collectively, these findings delineate a MYB/miR-486-5p/PTEN/AKT/mTOR signalling axis that constrains autophagy to facilitate HCC progression, suggesting potential avenues for biomarker development and therapeutic intervention.\n\nID: 42633397\nTitle: Research advances in microneedle-exosome delivery systems for the treatment of multisystem diseases.\nAbstract: The combined application of microneedles (MNs) and exosomes represents a significant research direction in the fields of targeted drug delivery and regenerative medicine. Their synergistic and complementary effects not only address key technical challenges associated with exosome delivery-such as low delivery efficiency and limited tissue penetration-but also endow MNs with capabilities for targeted therapy and precise diagnostics, thereby demonstrating substantial advantages in the diagnosis and treatment of multisystem diseases. This review summarizes recent advances in MN-exosome delivery systems across dermatological, cardiovascular and cerebrovascular, and musculoskeletal diseases, as well as tumor diagnosis and therapy, ocular surface disorders, and oral diseases. It focuses on the fabrication strategies, mechanisms of action, and therapeutic efficacy of various MN-based exosome delivery systems. Furthermore, it proposes research perspectives and potential solutions for diseases that respond poorly to conventional diagnostic and therapeutic approaches, providing a reference for the future development and clinical translation of MN-exosome systems.\n\nID: 42628399\nTitle: Surface-engineered GE11-functionalized exosomes for EGFR-targeted peonidin delivery and suppression of SNAI1-mediated epithelial-mesenchymal transition in glioma.\nAbstract: Glioblastoma is a highly aggressive and invasive brain tumor with poor prognosis, largely due to its rapid progression, epithelial-mesenchymal transition (EMT)-mediated invasiveness, and resistance to conventional therapies. Herein, the surface-engineered exosomal nanoplatform for targeted glioma therapy is functionalized glioblastoma-derived exosomes with the epidermal growth factor receptor (EGFR)-targeting GE11 peptide and loading them with peonidin (PN), a naturally occurring anthocyanin with anticancer potential. The engineered Exo-GE11/PN nanoparticles exhibited favorable physicochemical characteristics, including nanoscale size distribution, high encapsulation efficiency, colloidal stability, and preserved exosome morphology. GE11 functionalization significantly enhanced cellular uptake in EGFR-overexpressing glioma cells, facilitating efficient intracellular delivery of PN. In vitro studies demonstrated that Exo-GE11/PN effectively suppressed glioma cell proliferation, migration, and invasion while promoting apoptotic cell death. Mechanistic investigations revealed that the formulation attenuated EMT through downregulation of SNAI1 and modulation of the PI3K/Akt/NF-\u03baB signaling pathway, accompanied by restoration of epithelial markers and suppression of mesenchymal markers. Furthermore, Exo-GE11/PN significantly reduced tumor growth and improved survival in glioma-bearing mice without inducing clear systemic toxicity, confirming its biocompatibility and therapeutic efficacy. Collectively, these findings highlight the importance of exosome surface engineering for targeted drug delivery and demonstrate that GE11-functionalized exosomes serve as an effective biointerface-mediated carrier for peonidin. This biomacromolecular nanoplatform offers a promising strategy for EGFR-targeted glioblastoma therapy through the suppression of EMT-associated oncogenic signaling pathways.\n\nID: 42626960\nTitle: Emerging Biomaterials Revolutionizing Pre-Eclampsia Treatment.\nAbstract: Pre-eclampsia (PE)\u00a0is a complex pregnancy-specific disorder characterized by hypertension and proteinuria, posing significant risks to both maternal and fetal health. Despite ongoing efforts, drug development remains hindered by poor placental targeting, potential fetal toxicity, and limited biocompatibility. This review highlights the recent advances in biomaterials-based therapeutic strategies and diagnostic platforms for PE. We focus on the applications of targeted drug delivery nanosystems that aim to improve placental targeting specificity, enhance therapeutic efficacy, and minimize off-target effects. Emerging biomaterials-related drug delivery systems, including lipid nanoparticles, polymer nanoparticles, and hydrogels, along with biologically derived carriers or therapeutics such as adenoviral vectors and exosomes derived from mesenchymal stem cells, offer innovative solutions to overcome the existing pharmacological constraints such as poor target specificity, rapid clearance, and off-target toxicity. Additionally, cutting-edge technologies like organoids and organ-on-a-chip platforms provide powerful tools for advanced disease modeling and drug screening. For each drug delivery system and diagnostic platform, we summarize the most representative research achievements, emphasizing the design principles, application advantages, and practical limitations. By systematically introducing the various significant advances in recent years, this review offers insights into how biomaterial-based approaches address PE treatment challenges and may inspire the development of precise platforms for safe and effective therapy.\n\nID: 42623883\nTitle: Lithocholic based stimuli-responsive polymer capped silver nanoparticles: Assessment on bio interface driven colloidal stability, antimicrobial activity and ROS-mediated oral cancer therapy.\nAbstract: Stimuli-responsive polymeric micelles (PMs) provide promising plat forms for improving the stability and therapeutic efficacy of metal nanoparticles (MNPs) in biomedical applications. Herein, we report the synthesis of a cysteamine-functionalized poly (N-isopropylacrylamide-co-lithocholic acid) based amphiphilic copolymer, (poly(NIPAM-co-MELCA-Cys)), with thermo- and pH-responsive behavior and its stabilized silver nanoparticles (AgNPs). The copolymer exhibits primary and secondary critical aggregation concentration (CAC) at 3.84 x10-4 and 1.51x10-3 wt%, respectively, in aqueous media, together with tunable lower critical solution temperature (LCST) behavior. Under optimized alkaline conditions, poly(NIPAM- co- MELCA- Cys) facilitates the formation of spherical AgNPs with nearly uniform distribution and exhibit stability for more than a year. The colloidal stability of capped AgNPs was assessed in physiological media (NaCl, PBS, and FBS) using UV-Visible spectroscopy, DLS, and zeta potential measurements. Optical and morphological properties were analyzed by UV-visible spectroscopy, HR-TEM, DLS, XPS, and zeta potential techniques. MTT assay revealed dose-dependent cytotoxicity in KB cells, while 3T3-L1 cells showed lower sensitivity. ROS generation induced apoptosis, and flow cytometry confirmed G0/G1 arrest with increased apoptosis. These findings highlight the potential of poly(NIPAM-co-MELCA-Cys) for antimicrobial and ROS-mediated oral cancer therapy.\n\nID: 42620629\nTitle: IDH-genotype-linked kinase rewiring accompanies enhanced therapeutic response to dual-drug ferritin nanocages in high-grade glioma.\nAbstract: Therapeutic resistance and limited brain penetration remain major challenges in high-grade gliomas. Protein-based nanocarriers, such as the heavy chain of human ferritin (FTH1), facilitate transferrin receptor-mediated transport across the blood-brain barrier. Here, we present multifunctional FTH1 nanocages as a unified nanoplatform for dual-drug chemotherapy and molecular imaging. The nanocages achieve > 98\u202f% gallium-68 labeling efficiency and enable pH-responsive release of doxorubicin and paclitaxel. In isocitrate dehydrogenase (IDH)-wildtype and IDH-mutant tumor models in ovo, FTH1 nanocages exhibit robust intracerebral distribution, tumor accumulation, and enhanced therapeutic efficacy. Dual-drug nanocages significantly reduce tumor growth (p\u202f<\u202f0.001), with a stronger effect in the IDH-mutant model (p\u202f<\u202f0.001), and improve embryo survival. Kinomic profiling reveals broad suppression of AGC and CMGC kinase families, consistent with attenuation of pro-survival and cell-cycle signaling, particularly in IDH-mutant models. These findings suggest treatment-associated kinase network adaptation linked to the IDH status of the models, consistent with increased therapeutic vulnerability, and support further evaluation of FTH1 nanocages as a platform for improved glioma treatment.\n\nID: 42615169\nTitle: Polysaccharide Nanocomposite Hydrogel Prevents the Polarity Reversal of \u03b2-Glucan-Activated Macrophages by Lactate Oxidase-Based Lactate Depletion for Enhanced Immunotherapy.\nAbstract: Modulating the immunosuppressive tumor microenvironment (TME) represents a promising strategy for improving cancer immunotherapy. A key approach involves reprogramming tumor-associated macrophages (TAMs) from a protumorigenic M2 phenotype to an antitumorigenic M1 state. However, elevated lactate concentration in the TME not only sustains the M2 phenotype but also impairs therapeutic efficacy. To address this challenge, we developed an in situ injectable carboxymethyl chitosan/oxidized sodium alginate (CMCS/OSA) hydrogel with pH-responsive release properties, coloaded with another nanosized active polysaccharide \u03b2-glucan and a lactate-depleting agent lactate oxidase (LOX). Under the acidic conditions of the TME, Schiff base bonds within the hydrogel matrix dissociate, triggering the controlled release of \u03b2-glucan nanoparticles and LOX. The \u03b2-glucan nanoparticles specifically target TAMs via the dendritic cell-associated C-type lectin 1 (Dectin 1) receptor, facilitating their phenotypic conversion from M2 to M1. Simultaneously, the released LOX continuously degrades lactate, preventing the reversion of TAMs back to the M2 phenotype. Collectively, our results demonstrated that this nanocomposite polysaccharide hydrogel system effectively promoted and maintained TAM polarization toward the M1 phenotype through the synergistic effects of immune modulation and metabolic regulation, ultimately enhancing the efficacy of tumor immunotherapy.\n\nID: 42610073\nTitle: Nanotechnology in Prostate Cancer: PSMA-Targeted Nanoplatforms, TME-Responsive Therapy, Immunomodulation, and Clinical Translation Challenges.\nAbstract: The field of nanotechnology has demonstrated considerable potential in the diagnosis and treatment of prostate cancer, particularly through the use of prostate-specific membrane antigen (PSMA)-targeted platforms and tumor microenvironment (TME)-responsive systems. In the context of diagnosis, nanoparticle-based molecular imaging probes have been shown to enhance detection sensitivity and specificity. These probes include superparamagnetic iron oxide, which is utilized in magnetic resonance imaging, and near-infrared fluorescent nanomicelles. Additionally, nanostructured liquid biopsy systems have demonstrated the capability to capture circulating tumor cells, exosomes, and circulating tumor DNA with high sensitivity, facilitating non-invasive genotyping and treatment monitoring. In the field of therapeutics, PSMA-targeted liposomes, polymeric nanoparticles, and inorganic nanocarriers have demonstrated efficacy in enhancing the delivery of chemotherapeutics, gene-editing tools (eg, CRISPR/Cas9, siRNA), and immunomodulators. These delivery mechanisms are equipped with TME-responsive release mechanisms (eg, pH, enzyme, redox) that enable the spatiotemporal control of drug release. Nanotechnology offers multi-level strategies to overcome multidrug resistance in castration-resistant prostate cancer, including PROTAC-mediated protein degradation, ferroptosis induction, and synergistic chemo-immunotherapy. Multifunctional theranostic nanoplatforms integrating imaging and therapy enable real-time efficacy assessment and personalized treatment adaptation. Emerging green synthesis approaches that utilize agricultural byproducts and bio-inspired platforms (eg, cell membrane-coated nanoparticles) present sustainable and biocompatible alternatives. Concurrently, artificial intelligence (AI) holds the potential to expedite the design of nanocarriers. Despite the advancement of several nanomedicines to clinical trials, significant translational barriers persist. These include heterogeneous PSMA expression (15-37% of castration-resistant prostate cancer cases are PSMA-negative), suboptimal enhanced permeability and retention effect in humans, long-term safety concerns, manufacturing hurdles, and regulatory gaps. This narrative review methodically examines the applications of nanotechnology in prostate cancer. It critically analyzes the clinical translation challenges encountered during clinical trials and discusses future directions, including smart responsive systems, multimodal immunotherapy, and AI-assisted nanomedicine design.\n\nID: 42597591\nTitle: Beyond chemotherapy: The rise of nucleic acid nanoformulations in personalized lung cancer therapy.\nAbstract: Lung cancer remains the leading cause of cancer-related mortality worldwide, driven by complex crosstalk among genetic, molecular, and environmental factors. Conventional treatments, including immunotherapies and targeted inhibitors, face three main challenges: tumor heterogeneity, drug resistance, and systemic toxicity. Nucleic acid therapeutics (NATs) encompass a diverse array of DNA- and RNA-based tools, including small interfering RNA (siRNA), microRNA (miRNA), messenger RNA (mRNA), antisense oligonucleotides (ASOs), and clustered regularly interspaced short palindromic repeats (CRISPR)-associated (Cas) systems. These tools are central to developing precision oncology approaches that operate through direct gene regulation, mutation correction, and immune system reprogramming. The clinical application of NATs currently faces three main obstacles, which include their vulnerability to enzymatic degradation, their limited ability to penetrate tissues, and their tendency to cause off-target effects. The field has progressed through the implementation of nanoformulation techniques, which utilize lipid-based polymeric and metallic carriers together with exosomes and DNA origami, and hybrid nanostructures as new platforms to enhance the stability of drugs and their cellular absorption and targeted delivery to tumors. The scientists developed functionalized nanocarriers by combining targeting ligands with materials that could respond to specific environmental changes, which allowed them to manage drug distribution and release patterns throughout the tumor microenvironment. This review focuses on establishing a direct connection between nucleic acid design and nanotechnology through an analysis of mechanistic details and progress in preclinical and clinical research, and the difficulties encountered during the progress to practical applications. The research demonstrates how artificial intelligence and bioinspired nanocarriers and multi-omics data integration create new opportunities for developing personalized adaptive nanogenetic treatment methods, which will treat lung cancer. The current advancements indicate that we are approaching a transformative era in which nanomedicine and nucleic acid therapeutics will enable safe genetic alterations of cancer through targeted therapeutic applications.\n\nID: 42586674\nTitle: Lipid-conjugated amphiphilic chitosan: Review on synthesis, properties and application as potential anticancer nanomedicine.\nAbstract: Nanocarriers based on chitosan have become effective and biocompatible delivery systems for anticancer drugs that are poorly soluble. Recent developments in the design of amphiphilic chitosan derivatives modified with hydrophobic moieties, including fatty acids, cholesterol, bile acids, and functional ligands, are systematically compiled in this study. Such modifications allow for spontaneous self-assembly into micelles or nanoparticles that can encapsulate various hydrophobic drugs, including doxorubicin, paclitaxel, derivatives of camptothecin, and natural bioactives. The links between structure and properties that control drug loading, release kinetics, cellular uptake, and targeting efficiency are highlighted. In the context of tumor-specific microenvironments, pH-responsive behavior, ligand-mediated active targeting, and improved intracellular delivery are examined. Additionally, in vitro and in vivo data are used to critically assess strategies for enhancing bioavailability, overcoming multidrug resistance, and lowering systemic toxicity. To offer a comprehensive comparative overview of carrier design concepts, this paper schematically illustrates the synthesis methods and architectural diversity of several lipid-conjugated amphiphilic chitosan-based systems. All things considered, chitosan-derived amphiphilic nanocarriers are a promising and versatile family of drug delivery vehicles for enhancing the therapeutic efficacy of anticancer drugs.\n\nID: 42583925\nTitle: Mitigating breast cancer with intratumoral in situ pH-responsive abemaciclib-loaded novasome hydrogel.\nAbstract: Abemaciclib (AMC) is a selective CDK4/6 inhibitor widely utilised for breast cancer therapy; however, its efficacy is compromised by poor bioavailability and low aqueous solubility. This study aimed to enhance the sustained release, targeting, and efficacy of AMC via developing an intratumoral, in situ pH-responsive AMC-loaded novasome (IPANF) hydrogel. The optimal AMC-novasome was tailored using Design-Expert\u00ae software and subsequently incorporated into a chitosan/glyceryl monooleate mixture to develop IPANF. The in vivo anti-tumour efficacy and safety profile of the IPANF were evaluated using an Ehrlich ascites carcinoma model. Within 24\u2009h, the IPANF formulation exhibited a significantly sustained drug release by 65.31% compared to the free AMC suspension. The intratumoral IPANF resulted in a profound 96.08% reduction in tumour volume, a 70.46% recovery in body weight, and a suppression of the CA 15-3 and CA 27-29 levels by 92.66% and 91.23%, respectively. Notably, a 100% survival rate was observed in the intratumoral IPANF group. Histopathological assessments firmly validated the superior therapeutic efficacy of the intratumoral IPANF hydrogel. Furthermore, the intratumoral IPANF formulation demonstrated an excellent safety profile. These findings underscore the clinical potential of the intratumoral IPANF hydrogel as a highly efficient, localised, and safe platform for advanced breast cancer treatment.\n\nID: 42583391\nTitle: A bibliometric analysis of research trends and hotspots regarding macrophage polarization in lung cancer.\nAbstract: Macrophage polarization, which affects the lung cancer tumor microenvironment and treatment response through M1/M2 phenotypic transformation, has become a key research area. However, there is a lack of systematic bibliometric analysis. Therefore, this study employed bibliometric methods to comprehensively review the research trends and hotspots in this field. A comprehensive search was conducted using the Web of Science Core Collection (WoSCC) and Scopus databases for English-language literature published between January 1, 2010, and August 1, 2025. A multidimensional visual analysis of nations, institutions, authors, journals, references, and keywords was performed on the 508 included articles utilizing bibliometric tools VOSviewer, CiteSpace, and Bibliometrix. The number of publications in this field shows an upward trend. From 2010 to 2016, it was in the initial growth stage; from 2017 to 2021, it entered a period of steady growth. After 2022, research activities increased significantly and reached a peak in 2025 (n=131). Frontiers in Immunology (n=25) had the highest number of publications, while Nature Nanotechnology (1,299) had the highest co-citation frequency. Wang Yi-Ching (n=5, H-index =4) and Yang Bo (n=4, H-index =4) are the core authors representing the development of this discipline. China (n=370) has the largest number of publications, and representative institutions include Fudan University (n=19), Chinese Academy of Medical Sciences (n=15), and Shanghai Jiao Tong University (n=14). The USA (94.65) demonstrates the most significant academic influence. Research hotspots have gradually shifted from the correlation between the early macrophage polarization phenotype and the pathological characteristics of lung cancer to molecular mechanisms such as signaling pathways, metabolic reprogramming, and exosomes, and have further expanded to the directions of nanoparticle targeted delivery and clinical translation of immune checkpoint inhibitors. The research in this field has advanced from phenotypic description to mechanism integration and translational research, with nano-intervention and immune regulation being the cutting-edge directions. In the future, attention should be focused on the clinical translation pathways of personalized regulation strategies.\n\nID: 42580228\nTitle: Self-cascade nanozyme electrochemical platform with antifouling COFs-derived nanohydrogel: High-precision detection of circulating SAPs for breast cancer metastasis prediction.\nAbstract: Breast cancer following metastatic dissemination is associated with high mortality rates, severely threatening women's health. As principal mediators of intercellular communication within the tumor microenvironment, secretory autophagosomes (SAPs) propel breast cancer progression and metastasis by modulating the establishment of the pre-metastatic niche, thereby positioning them as highly promising biomarkers for breast cancer. However, the paucity of accurate and simplified quantitative tools has impeded the direct detection of circulating SAPs. This study presents a sensing platform that couples nanozyme cascade catalysis with a covalent organic frameworks (COFs)-derived nanohydrogel (CGNH) for precisely assessing trace-level SAPs. The AuNBP@PtPd-MoS2 nanozyme, via its stereoconfiguration and trimetallic synergy, recapitulates the dual enzyme-mimicking activities of GOx/CAT. Hence, it enables self-sustained interfacial charge transfer. As a signal probe, it efficiently accelerates self-cascade catalysis and electrochemical mass transfer. Additionally, CGNH creates an ideal interface for SAPs enrichment and cascade catalysis, featuring a hierarchical pore structure, a hybrid conductive network, and suitable biocompatibility. With self-assembled antifouling peptide nanoparticles (APNP) as a shielding barrier, the platform reliably detects SAPs in intricate biological matrices verified using cellular, murine and clinical specimens. Compared with conventional biomarkers, SAPs produce more informative readouts on disease progression. This electrochemical platform differentiates between benign and malignant breast diseases and healthy controls with high diagnostic accuracy (AUC\u202f=\u202f0.962), especially for gray-zone differentiation and metastasis forecasting. This study offers new avenues for SAPs-based liquid biopsy to identify signs of breast cancer metastasis and is expected to become a reliable non-invasive tool for personalized breast cancer management.\n\nID: 42579394\nTitle: Engineered Brain-Targeted Exosomes Delivering FGF1 for Sustained Glycemic Regulation and Multitarget Neurovascular Protection in Diabetic Stroke.\nAbstract: Diabetic stroke is characterized by a hyperglycemic and pro-inflammatory microenvironment that exacerbates neurovascular dysfunction. However, the blood-brain barrier (BBB) remains a formidable obstacle, restricting the delivery of most therapeutic molecules. To address this, we developed a non-invasive treatment strategy using engineered exosomes. Specifically, we fabricated FGF1-loaded exosomes functionalized with the rabies virus glycoprotein (RVG) peptide (FGF1-RVG Exo). This platform facilitates selective, neuron-targeted delivery of FGF1 to the ischemic penumbra via RVG-mediated transcytosis. In a diabetic stroke mouse model, FGF1-RVG Exo exhibited superior pharmacological efficacy compared to free FGF1, achieving robust therapeutic outcomes with only once-weekly administration. Notably, a single dose during the acute phase elicited a sustained hypoglycemic effect lasting up to two weeks and effectively ameliorated systemic insulin resistance. Locally, the accumulation of exosomes within the lesion led to a significant reduction in infarct volume and cell apoptosis, while promoting neovascularization and the recovery of motor and cognitive functions. This brain-targeted strategy achieves a peripheral-central synergistic modulation, addressing the multi-target requirements of diabetic stroke management. Collectively, our findings provide a novel paradigm for treating diabetic ischemic stroke and a potent strategy for the targeted delivery of growth factors to the central nervous system.\n\nID: 42576909\nTitle: Mitochondria-targeted peptide-engineered bimetallic nanozymes enable ferroptosis-sensitized cuproptosis for melanoma therapy.\nAbstract: Developing nanotherapeutics to circumvent intrinsic apoptosis resistance in cancer remains a key challenge in oncology. Cuproptosis, a non-apoptotic cell death modality, has emerged as a promising alternative, yet its therapeutic efficacy is frequently limited by robust intracellular antioxidant defense systems. Here, we developed an ultrasmall (ca.10\u202fnm) mitochondria-targeted bimetallic nanozyme (RMOCZ) for synergistic ferroptosis-cuproptosis therapy against malignant melanoma. The Cu/Zn bimetallic core, functionalized with a chimeric mitochondrial targeting peptide, serves as both a pH-responsive copper reservoir and a dual-enzyme mimetic (peroxidase and glutathione oxidase). Upon endolysosomal acidification, RMOCZ disassembles to co-release copper ions and oridonin (ORI). The nanozyme oxidizes intracellular glutathione (GSH), a process significantly accelerated by co-delivered ORI. This disruption of redox homeostasis not only triggers ferroptosis by compromising cellular antioxidant capacity but also amplifies peroxidase-mediated reactive oxygen species (ROS) production, sensitizing tumor cells to copper-induced cytotoxicity. Concurrently, RMOCZ induces ferritinophagy to mobilize the endogenous labile iron pool and exacerbate lipid peroxidation. These events culminate in sustained copper-iron dual-ion overload. Following subsequent mitochondrial trafficking, the accumulated copper ions trigger canonical cuproptotic events, including the degradation of iron-sulfur (Fe-S) clusters and aberrant oligomerization of lipoylated DLAT. This irreversible mitochondrial dysfunction triggers potent immunogenic cell death (ICD) with robust damage-associated molecular patterns (DAMPs) release. In situ immunohistochemical analyses confirm that this RMOCZ-induced ICD profoundly remodels the immunosuppressive\u00a0microenvironment, promoting CD86+ antigen-presenting cell maturation and enhancing intratumoral infiltration of CD3+ and CD8+ T cells. In vivo, RMOCZ demonstrates substantial melanoma regression with negligible systemic toxicity, providing a promising strategy for treating apoptosis-resistant refractory malignancies.\n\nID: 42576814\nTitle: Exosome-based nanomedicine for neurological disorders: mechanisms, engineering, and therapeutic potential.\nAbstract: Exosomes are naturally occurring extracellular vesicles that have emerged as promising bio-inspired nanocarriers for the treatment of neurological disorders owing to their intrinsic biocompatibility, low immunogenicity, and ability to cross the blood-brain barrier. This review highlights recent advances in exosome biology, cargo-sorting mechanisms, and engineering strategies designed to enhance therapeutic delivery and targeting within the central nervous system. Particular emphasis is placed on the application of engineered exosomes in neurodegenerative diseases, stroke, spinal cord injury, neuropathic pain, and neuroinflammatory disorders. In addition, we discuss how exosomes compare with conventional delivery platforms and critically examine the major barriers limiting their clinical translation, including heterogeneity, scalability, reproducibility, purity, and regulatory standardization. By integrating mechanistic insights with translational perspectives, this review provides a framework for the rational design and future clinical implementation of exosome-based nanomedicines for neurological disorders. Relevant literature was identified through searches of PubMed, Scopus, Web of Science, and Google Scholar. Publications available from database inception through [Month Year] were screened using combinations of keywords including \"exosomes,\" \"extracellular vesicles,\" \"neurological disorders,\" \"brain-targeted delivery,\" \"exosome engineering,\" \"drug delivery,\" and \"clinical trials.\" Additional relevant articles were identified through manual searches of reference lists from selected studies and recent reviews. Exosomes are tiny natural particles released by cells that act as messengers, carrying proteins and genetic material between cells. Scientists are increasingly studying these particles because they may help deliver medicines to the brain and spinal cord, where many treatments struggle to reach due to protective barriers. This review explains how exosomes are formed, how they can be modified to carry drugs or therapeutic molecules, and how they may help treat diseases affecting the nervous system, including Alzheimer\u2019s disease, Parkinson\u2019s disease, stroke, multiple sclerosis, spinal cord injury, and certain neuropsychiatric disorders.We also discuss the advantages of exosomes compared with conventional drug delivery systems and summarize recent advances in engineering strategies that improve their targeting abilities. Although laboratory studies have produced encouraging results, many challenges remain before exosome-based therapies can become routine treatments. These include difficulties related to large-scale production, quality control, safety, and ensuring that exosomes reach the desired tissues without causing unwanted effects.In addition, this review highlights current clinical studies and discusses the steps needed to translate these discoveries into real-world therapies. Overall, exosomes represent an exciting and rapidly evolving area of research that may contribute to the development of safer and more effective treatments for neurological disorders in the future.\n\nID: 42569222\nTitle: Macrophage-reprogramming calcium alginate microspheres enhance exosome-mediated antigen cross-presentation to boost embolization-immunotherapy in hepatocellular carcinoma.\nAbstract: Transarterial chemoembolization (TACE) is a first-line therapeutic modality for hepatocellular carcinoma (HCC). Nevertheless, its therapeutic efficacy remains constrained by the hostile tumor microenvironment (TME), typified by acidity and an immunosuppressive milieu. Here, multifunctional microspheres (RC6CaAlgMS) were developed to neutralize the acidic TME and relieve immunosuppression. The uniform-sized calcium alginate microspheres were fabricated using microfluidic technology, incorporating pH-responsive CaCO3 nanocarriers to efficiently encapsulate R848 and C6-ceramide (C6). Their physicochemical properties were characterized, and the embolization efficiency was validated using decellularized liver and rabbit kidney models. Furthermore, their antitumor activities and mechanism were evaluated in both in vitro and in vivo. R848 and C6 were efficiently encapsulated into RC6CaAlgMS, where they acted synergistically to reprogram tumor-associated macrophages (TAMs) toward an M1-like phenotype and to enhance both exosome secretion and exosome-mediated antigen cross-presentation. RC6CaAlgMS produced uniform vascular embolization and efficiently occluded the renal arterial branches. In vitro studies demonstrated that RC6CaAlgMS synergized with DOX-based chemotherapy to suppress the growth of murine HCC by neutralizing acidic TME and remodeling the immune landscape. When combined with PD-L1 blockade therapy, DOX-loaded RC6CaAlgMS effectively inhibited both primary and distant tumors, eliciting an abscopal-like effect driven by enhanced antigen dissemination and T-cell priming. In an orthotopic rat TACE model, the combination of DOX-loaded RC6CaAlgMS with PD-L1 blockade achieved complete tumor eradication. Collectively, this study establishes a multifunctional microsphere platform that effectively remodels and overcomes the post-TACE immunosuppressive TME, offering a potent strategy for integrating embolization with immunotherapy in HCC.\n\nID: 42566931\nTitle: Engineered tumor cell membrane-coated manganese-amplified STING nanoagonist potentiates PD-L1 blockade immunotherapy in non-small cell lung cancer.\nAbstract: Immune checkpoint blockade targeting the PD-1/PD-L1 axis has improved the treatment of non-small cell lung cancer (NSCLC), yet its therapeutic efficacy remains limited by insufficient antitumor immune activation. Herein, we developed a biomimetic manganese-amplified STING nanoagonist to potentiate PD-L1 blockade immunotherapy. Hollow mesoporous manganese silicate nanoparticles were engineered as Mn2\u207a-releasing nanocarriers for loading a STING agonist (Sa) diABZI, followed by coating with anti-PD-L1 antibody-functionalized NSCLC tumor cell membranes. The resulting Sa@HMMSN@PM exhibited pH-responsive Sa release, preserved PD-L1 blocking activity, and enhanced tumor-cell-selective uptake. Mechanistically, Mn2\u207a released from HMMSN promoted cGAMP production, while Sa further enhanced STING phosphorylation, leading to robust STING activation. Sa@HMMSN@PM showed enhanced tumor accumulation, superior tumor growth inhibition and prolonged survival in both subcutaneous and orthotopic NSCLC mouse models. Further mechanistic studies demonstrated increased IFN-\u03b2, CXCL10, TNF-\u03b1, IL-6, and IFN-\u03b3 levels, together with enhanced CD4\u207a and CD8\u207a T-cell infiltration. Importantly, Sa@HMMSN@PM exhibited favorable biosafety without obvious systemic toxicity. Overall, this biomimetic Mn2\u207a-amplified STING nanoagonist provides a promising strategy for integrating innate immune activation with immune checkpoint blockade for enhanced NSCLC immunotherapy.\n\nID: 42546485\nTitle: Exosomes derived from different sources of mesenchymal stem cells attenuate cisplatin-induced ovarian toxicity.\nAbstract: Premature ovarian insufficiency (POI) poses significant challenges to reproductive health due to follicular depletion and hormonal dysregulation. Despite advances in stem cell therapy, clinical translation remains hindered by donor variability and ethical constraints. This study evaluates the therapeutic potential of exosomes derived from induced pluripotent stem cell-derived mesenchymal stem cells (iPSCMSC-exo) versus umbilical cord-derived MSC exosomes (hUCMSC-exo) for POI intervention. In vitro, both exosome types enhanced migration and tube formation of human umbilical vein endothelial cells (HUVECs), while iPSCMSC-exo additionally promoted proliferation. iPSCMSC-exo attenuated cisplatin-induced granulosa cell apoptosis, while both types suppressed p21-mediated cell cycle arrest. In the cisplatin-induced POI mouse model, exosome treatment effectively restored Follicle-stimulating hormone (FSH) levels. However, the therapeutic efficacy of exosomes in restoring anti-M\u00fcllerian hormone (AMH) levels and follicle counts was limited, as confirmed by synchrotron radiation microtomography revealing persistent structural depletion. Notably, iPSCMSC-exo demonstrated functional outcomes similar to hUCMSC-exo. The autologous origin and scalable production of iPSCMSCs address donor heterogeneity and supply limitations inherent to traditional MSC sources. Further optimization of targeted delivery systems is warranted to overcome biodistribution challenges and enhance structural regeneration.\n\nID: 42543528\nTitle: Encapsulation and Controlled Release of Human Spinal Cord Organoid-Derived Extracellular Vesicles for Tissue Patterning in Viscoelastic Hyaluronic Acid Hydrogels.\nAbstract: Human induced pluripotent stem cells (hiPSCs) can differentiate into various types of central nervous system organoids which are valuable for applications in tissue engineering and injury repair. The secreted extracellular vesicles (EVs) of organoids, in particular the small-sized EV subset referred as exosomes (30-200\u00a0nm), have emerged as novel therapeutics in regenerative medicine. This study investigated the encapsulation and controlled release of human spinal cord organoid (hSCO)-derived EVs in viscoelastic hyaluronic acid (HA) hydrogels and assessed their impact on organoid patterning. A series of pH-responsive hydrogels were fabricated, leading to sustained EV release regulated by viscoelastic properties. The pH of these hydrogels decreased from 9 to 7 during incubation, which altered hydrogel viscoelasticity, thereby modulating EV release kinetics. In addition, EV-loaded hydrogels regulated key hSCO patterning markers such as DBX1 and ISL1. Furthermore, these EVs in hydrogels can cross a modeled blood-spinal cord barrier and provide cross-barrier capability for delivery. Taken together, the organoid-secreted EVs in viscoelastic HA hydrogels can be released at a controlled rate and have potential to regulate spinal cord organoid patterning. This study advances our knowledge of regulating intercellular communication and developing EV-based therapies for treating neurological disorders such as spinal cord injury.\n\nID: 42543292\nTitle: [Research progress of biomimetic membrane preparation for myocardial ischemic injury treatment].\nAbstract: Myocardial ischemic injury threatens human health. While monomers or compound formulas of TCM can ameliorate such injury through multi-target and multi-pathway mechanisms, their clinical efficacy is hampered by poor targeting and low bioavailability. In recent years, biomimetic membrane preparations, primarily biomimetic cell membrane preparations and exosomes, have emerged as a novel therapeutic strategy for myocardial ischemic injury. Owing to their natural bioactivity, easy engineerability, and other characteristics, they enable the targeted delivery of TCM components to ischemic lesions and facilitate their transport across biological barriers. This review focused on the core pathological mechanisms of myocardial ischemic injury, elaborated on the types and unique functions of biomimetic cell membrane preparations and exosomes, and provided a critical analysis of the design strategies and action mechanisms of such biomimetic cell membrane preparations. Furthermore, it discussed the adaptability of different administration routes and highlighted the potential and the existing challenges of natural biomimetic membrane preparations. The aim of this study is to offer insights for the design, research, and development of biomimetic preparations for myocardial ischemic injury.\n\nID: 42543148\nTitle: Advances in Exosome-Based Therapy for Cardiovascular Disease: Traditional Chinese Medicine Offering New Avenues for Exosome Functionalization.\nAbstract: Cardiovascular diseases (CVDs) remain a leading cause of global mortality and impose a substantial health and economic burden worldwide. Exosomes, as promising endogenous nanocarriers, have emerged as a powerful tool for the prevention and treatment of CVDs. In particular, advanced functionalization strategies have largely enhanced exosomal therapeutic efficacy in\u00a0vivo. Notably, Traditional Chinese Medicine (TCM) and its bioactive components exert profound regulatory effects on exosomes. In this review, we systematically summarize exosome-based therapeutic strategies for CVDs, along with state-of-art functionalization approaches to optimize exosomal cargo loading and targeted delivery. We further provide a comprehensive overview of TCM-mediated exosomal regulation. We found that TCM and TCM-derived chemicals can optimize exosomal cargo loading, especially the loading of microRNAs (miRNAs) and bioactive chemicals. More importantly, TCM and chemicals can promote exosomal secretion, which provides new avenues for exosomal-scale production. Besides, there are synergistic effects between exosomes and TCM when co-administered. Collectively, exosome-based systems hold great promise for CVD therapy, and TCM provides novel strategies for exosomal functionalization, which substantially enhances exosomal-mediated therapeutic efficacy for CVDs.\n\nID: 42540442\nTitle: Augmented therapeutic efficacy of Erianin through pH-responsive charge-reversal liposome integrated synergistic PTT and PDT in breast cancer.\nAbstract: To address Erianin's limited solubility and the insufficient efficacy of single-modality chemotherapy, a charge-reversal liposomal system co-encapsulating Erianin and IR780 was designed. The liposomes maintain a negative surface charge under physiological conditions to prolong circulation, but undergo pH-responsive conversion to a positive charge within the acidic tumor microenvironment (pH 6.5-6.8), thereby improving tumor-selective internalization. The optimized formulation achieved targeted mitochondrial delivery, where IR780-induced reactive oxygen species (ROS) production and mild hyperthermia activated stress pathways, leading to mitochondrial disruption and ultimately initiating immunogenic cell death (ICD). Concurrently, encapsulated Erianin effectively suppressed photothermal therapy (PTT)/photodynamic therapy (PDT)-induced programmed cell death ligand 1 (PD-L1) upregulation. This nanoplatform not only avoids the drawbacks of conventional chemotherapy but also establishes a synergistic therapeutic framework integrating PTT, PDT, and chemotherapy. By counteracting resistance mechanisms and limiting immune checkpoint expression, the system provides robust antitumor activity and introduces an innovative approach for advancing liposomal strategies in combinatorial cancer therapy.\n\nID: 42526345\nTitle: Exosome-mediated delivery of 3-n-butylphthalide rescues microglial energy crisis and ameliorates neuroinflammation in ischemic stroke.\nAbstract: Stroke remains the second leading cause of death and the primary cause of long-term disability worldwide, with ischemic stroke accounting for the majority of cases. Ischemia triggers robust microglial activation, yet the precise regulatory mechanisms underlying microglial functional reprogramming remain incompletely understood. Here, we demonstrate that excessive mitophagy drives metabolic energy failure in microglia following cerebral ischemia, resulting in impaired phagocytosis and exacerbated neuroinflammation. Analysis of single-cell RNA-sequencing data from mouse brains in the sham, transient middle cerebral artery occlusion (tMCAO, mMCAO), and permanent middle cerebral artery occlusion (pMCAO, sMCAO) groups revealed that mitophagy was markedly activated in microglia under sustained ischemia and was associated with impaired phagocytic and cytoskeletal pathways. In vitro oxygen-glucose deprivation (OGD) assays showed that phagocytosis of apoptotic neurons by microglia induced upregulation of Drp1, triggering excessive mitochondrial fission and mitophagy, which caused ATP depletion and reduced clearance capacity. The mitophagy inhibitor 3-methyladenine alleviated inflammatory responses but failed to restore mitochondrial quality. In contrast, 3-n-butylphthalide (NBP) stabilized mitochondrial membrane potential, restored ATP production, and improved microglial phagocytic defects and inflammation. To achieve targeted delivery, we constructed BV2 microglia-derived exosomes encapsulating NBP (BV2exo@ NBP), which efficiently enhanced drug accumulation in ischemic lesions and significantly improved neurological outcomes in stroked mice. These results identify excessive mitophagy as a core mechanism underlying microglial energy crisis after cerebral ischemia and provide a mitochondria-targeted therapeutic strategy for ischemic stroke. Importantly, the neuroprotective efficacy, mitochondrial restoration, and anti-inflammatory effects of BM@NEB were fully recapitulated in 18-month-old aged mice, a clinically relevant model that more closely reflects the stroke patient population, supporting the translational potential of this exosome-based therapeutic strategy.\n\nID: 42525490\nTitle: Formulation and evaluation of etoposide-loaded dextran polymeric nanoparticles fabricated with hyaluronic acid for the treatment of colorectal cancer using network pharmacology, in-silico, in-vitro, and in-vivo approaches.\nAbstract: Etoposide (ETP), a Biopharmaceutics Classification System class IV drug with poor aqueous solubility, demonstrates limited therapeutic efficacy against colorectal cancer (CRC) because of inferior absorption and off-target effects. To deliver drugs specifically to cancer cells that overexpress CD44, this study developed hyaluronic acid (HA)-functionalized dextran (DEX) polymeric nanoparticles (ETP-DEX-HA-NPs). Optimised nanoparticles (174.7\u2009\u00b1\u20093.2\u2009nm, -12.83\u2009\u00b1\u20091.1\u2009mV) demonstrated significant entrapment efficiency (62.75\u2009\u00b1\u20092.32%) and drug loading (55.64\u2009\u00b1\u20093.86%), with partial amorphization validated by FTIR, XRD, Raman, NMR and DSC analyses. The formulation exhibited prolonged, pH-responsive release, markedly improved solubility (p\u2009<\u20090.05), and greater cytotoxicity in HCT-116 cells (IC50: 6.83\u2009\u00b1\u20090.35\u2009\u00b5g/mL compared to 41.89\u2009\u00b1\u20091.02\u2009\u00b5g/mL for free ETP). It facilitated CD44-mediated uptake, enhanced apoptosis, induced G2/M arrest, elevated ROS production and inhibited migration while preserving biocompatibility. Network pharmacology and molecular docking identified key interactions with CRC-related targets (e.g. TOP2A, BCL2). ETP-DEX-HA-NPs offer a promising, targeted nanoplatform that addresses ETP's limitations, boosting therapeutic efficacy and safety for CRC treatment.\n\nID: 42522609\nTitle: [Research progress on extracellular vesicles in aortic aneurysms].\nAbstract: Aortic aneurysms, including thoracic aortic aneurysms (TAA) and abdominal aortic aneurysms (AAA), represent a group of severe vascular lesions with insidious onset and high mortality. Currently, effective diagnostic markers and pharmacological interventions remain lacking in clinical practice. Extracellular vesicles (EVs), as key mediators of intercellular communication, have attracted increasing attention in the research on aortic aneurysms due to their high content of bioactive molecules, favorable biocompatibility, low immunogenicity, and inherent targeting capacity. This review systematically elaborated on the research progress on EVs in TAA and AAA, highlighting their significant role in the development and progression of aortic aneurysms. EVs play a crucial role by mediating core pathological processes, including endothelial dysfunction, phenotypic transformation of vascular smooth muscle cells, inflammatory immune responses, and extracellular matrix remodeling. Additionally, this review discussed the potential of disease-specific molecules carried by EVs as novel liquid biopsy markers for the early diagnosis of aortic aneurysms. Furthermore, this review evaluated the application prospects of EVs as natural drug delivery platforms and EV-based therapeutic strategies for aortic aneurysm through engineering modifications (such as targeting peptide modification and biomaterial integration). In particular, \"cell-free\" immunomodulatory therapies, which enhance targeting capacity to lesion sites through engineering modifications and focus strategically on regulating the phenotype and function of key immune cells (such as macrophages), are increasingly emerging as a cutting-edge direction with the greatest translational potential in this field. Despite challenges such as targeted delivery, the integration of engineering technologies with nanomedicine holds promise for opening new avenues for the precise prevention and treatment of aortic aneurysms through EV-based integrated diagnostic and therapeutic strategies. \u4e3b\u52a8\u8109\u7624\u5305\u62ec\u80f8\u4e3b\u52a8\u8109\u7624(thoracic aortic aneurysm, TAA)\u548c\u8179\u4e3b\u52a8\u8109\u7624(abdominal aortic aneurysm, AAA)\uff0c\u662f\u4e00\u7c7b\u53d1\u75c5\u9690\u533f\u4e14\u81f4\u6b7b\u7387\u9ad8\u7684\u4e25\u91cd\u8840\u7ba1\u75c5\u53d8\uff0c\u76ee\u524d\u4e34\u5e8a\u4e0a\u5c1a\u7f3a\u4e4f\u6709\u6548\u7684\u8bca\u65ad\u6807\u5fd7\u7269\u53ca\u836f\u7269\u5e72\u9884\u624b\u6bb5\u3002\u7ec6\u80de\u5916\u56ca\u6ce1(extracellular vesicles, EVs)\u662f\u7ec6\u80de\u95f4\u901a\u8baf\u7684\u5173\u952e\u4ecb\u8d28\uff0c\u56e0\u5176\u643a\u5e26\u4e30\u5bcc\u7684\u751f\u7269\u6d3b\u6027\u5206\u5b50\u4e14\u5177\u5907\u826f\u597d\u7684\u751f\u7269\u76f8\u5bb9\u6027\u3001\u4f4e\u514d\u75ab\u539f\u6027\u548c\u5929\u7136\u9776\u5411\u6027\uff0c\u5728\u4e3b\u52a8\u8109\u7624\u76f8\u5173\u7814\u7a76\u4e2d\u65e5\u76ca\u53d7\u5230\u5173\u6ce8\u3002\u672c\u6587\u7cfb\u7edf\u9610\u8ff0\u4e86EVs\u5728TAA\u548cAAA\u4e2d\u7684\u7814\u7a76\u8fdb\u5c55\uff0c\u91cd\u70b9\u603b\u7ed3\u4e86EVs\u5728\u4e3b\u52a8\u8109\u7624\u53d1\u751f\u53d1\u5c55\u4e2d\u7684\u91cd\u8981\u4f5c\u7528\u3002EVs\u901a\u8fc7\u4ecb\u5bfc\u5185\u76ae\u529f\u80fd\u969c\u788d\u3001\u8840\u7ba1\u5e73\u6ed1\u808c\u7ec6\u80de\u8868\u578b\u8f6c\u6362\u3001\u708e\u75c7\u514d\u75ab\u53cd\u5e94\u53ca\u7ec6\u80de\u5916\u57fa\u8d28\u91cd\u5851\u7b49\u6838\u5fc3\u75c5\u7406\u8fc7\u7a0b\u53d1\u6325\u91cd\u8981\u4f5c\u7528\u3002\u540c\u65f6\uff0c\u672c\u6587\u63a2\u8ba8\u4e86EVs\u643a\u5e26\u7684\u75be\u75c5\u7279\u5f02\u6027\u5206\u5b50\u5728\u4e3b\u52a8\u8109\u7624\u65e9\u671f\u8bca\u65ad\u4e2d\u5c55\u73b0\u51fa\u4f5c\u4e3a\u65b0\u578b\u6db2\u4f53\u6d3b\u68c0\u6807\u5fd7\u7269\u7684\u6f5c\u529b\u3002\u6b64\u5916\uff0c\u8fd8\u8bc4\u4f30\u4e86EVs\u4f5c\u4e3a\u5929\u7136\u836f\u7269\u9012\u9001\u5e73\u53f0\u53ca\u57fa\u4e8e\u5de5\u7a0b\u5316\u4fee\u9970(\u5982\u9776\u5411\u80bd\u4fee\u9970\u3001\u751f\u7269\u6750\u6599\u7ed3\u5408)\u7684\u4e3b\u52a8\u8109\u7624\u6cbb\u7597\u7b56\u7565\u7684\u5e94\u7528\u524d\u666f\uff0c\u5c24\u5176\u662f\u901a\u8fc7\u5de5\u7a0b\u5316\u4fee\u9970\u589e\u5f3a\u5176\u5bf9\u75c5\u53d8\u90e8\u4f4d\u7684\u9776\u5411\u80fd\u529b\uff0c\u4ee5\u8c03\u63a7\u5173\u952e\u514d\u75ab\u7ec6\u80de(\u5982\u5de8\u566c\u7ec6\u80de)\u8868\u578b\u4e0e\u529f\u80fd\u4e3a\u7b56\u7565\u6838\u5fc3\u7684\u201c\u65e0\u7ec6\u80de\u201d\u514d\u75ab\u8c03\u8282\u7597\u6cd5\uff0c\u65e5\u76ca\u6210\u4e3a\u8be5\u9886\u57df\u6700\u5177\u8f6c\u5316\u6f5c\u529b\u7684\u524d\u6cbf\u65b9\u5411\u3002\u5c3d\u7ba1\u9762\u4e34\u9776\u5411\u9012\u9001\u7b49\u6311\u6218\uff0c\u4f46\u968f\u7740\u5de5\u7a0b\u5316\u6280\u672f\u4e0e\u7eb3\u7c73\u533b\u5b66\u7684\u878d\u5408\uff0c\u57fa\u4e8eEVs\u7684\u8bca\u7597\u4e00\u4f53\u5316\u7b56\u7565\u6709\u671b\u4e3a\u4e3b\u52a8\u8109\u7624\u7684\u7cbe\u51c6\u9632\u6cbb\u5f00\u8f9f\u65b0\u8def\u5f84\u3002.\n\nID: 42501943\nTitle: PEG-g-(HEMA-co-AA) pH-responsive graft copolymer: A promising approach for the controlled oral delivery of acid-labile rabeprazole sodium.\nAbstract: This research presents the development of a novel pH-sensitive PEG (HEMA-co-AA) graft copolymer hydrogel designed to provide controlled and protective delivery of acid-labile drugs, specifically Rabeprazole sodium. The hydrogel was synthesized using polyethylene glycol (PEG), 2-hydroxyethyl methacrylate (HEMA), acrylic acid (AA), with N,N'-methylene bisacrylamide (MBA) as a cross-linker and potassium persulfate (KPS) as an initiator. The hydrogel's structural integrity and formation were confirmed through Fourier-transform infrared spectroscopy (FTIR), scanning electron microscopy (SEM), differential scanning calorimetry (DSC), and swelling studies. It is noteworthy that the hydrogel exhibits a different pH-dependent swelling behaviour, which expands under alkaline conditions and maintains its compact structure under acidic conditions. The content of acrylic acid contributed to the high-water retention and the swelling profile indicated that the product was suitable for the specific release of the drug at the site. The in-vitro release of rabeprazole sodium at acidic pH is very low, thus protecting rabeprazole sodium from premature degradation in the stomach; however, controlled release of rabeprazole sodium was achieved at intestinal pH via a non-Fickian diffusion mechanism (Korsmeyer-Peppas n = 0.40-0.62, Higuchi R\u00b2 = 0.991-0.996) over 12 h. Moreover, in-vivo acute toxicity studies indicated that the hydrogel is highly biocompatible, suggesting it is safe for use in future therapeutic applications. Overall, the PEG (HEMA-co-AA) hydrogel represents a versatile vehicle for the controlled and local administration of acid-labile pharmaceuticals, thereby promoting increased therapeutic efficacy.\n\nID: 42656015\nTitle: Spatiotemporal Remodeling of the Tumor-Draining Lymph Node Microenvironment During Head and Neck Cancer Metastasis.\nAbstract: The spatiotemporal evolution of the tumor-draining lymph node microenvironment remains incompletely characterized in head and neck squamous cell carcinoma (HNSCC). Using a reproducible buccal xenograft model with serial time-point and spatial analyses, we aimed to define stage-and region-resolved microenvironmental remodeling during cervical lymph node metastasis. A buccal xenograft model of cervical lymph node metastasis was used, and tumor-draining lymph nodes were analyzed at serial time points using immunofluorescence staining and confocal microscopy. The lymphovascular architecture, stromal remodeling, hypoxia, and immune cell distribution were evaluated during metastatic progression. The model reproducibly induced cervical lymph node metastasis with a gradual temporal progression. Before overt tumor colonization, tumor-draining lymph nodes showed features of a pre-metastatic niche, including expansion of LYVE-1\u207a lymphatic vessels, remodeling of high endothelial venules, and increased recruitment of CD11b\u207a myeloid cells and F4/80\u207a macrophages. Confocal imaging revealed that the tumor cells were initially localized within the subcapsular sinus lymphatic vessels and subsequently expanded into the lymph node parenchyma. During invasive progression, metastatic regions showed progressive loss of CD31\u207a blood vessels and LYVE-1\u207a lymphatic vessels, accompanied by GLUT1 upregulation, fibrinogen deposition, disruption of PDGFR\u03b2\u207a fibroreticular networks, and spatially organized myeloid cell accumulation at the invasive front. This study delineated a stage- and region-resolved sequence of nodal microenvironmental remodeling during HNSCC metastasis, linking premetastatic lymphovascular changes to intralymphatic tumor colonization and subsequent invasive regional remodeling. These findings provide an integrated spatiotemporal framework for understanding the progression of the metastatic lymph node microenvironment.\n\nID: 42653341\nTitle: Comprehensive Review of Extracellular Vesicles in Thyroid Cancer: From Methodological Approaches to Biological Functions and Clinical Applications.\nAbstract: Thyroid cancer (TC) is one of the most common endocrine malignancies and ranks among the ten most frequently diagnosed cancers worldwide, highlighting the need for improved diagnostic and monitoring strategies. Extracellular vesicles (EVs) are nano-sized, membrane-enclosed particles released by nearly all cell types that carry selectively sorted bioactive cargo capable of influencing the behavior and fate of recipient cells. Although their molecular composition is shaped by their cells of origin, cargo loading is a regulated process that contributes to EV-mediated intercellular communication and cell-specific targeting. In TC, EVs have emerged as important mediators of tumor progression and microenvironment modulation. Recent advances underscore the diagnostic and prognostic value of EVs as non-invasive biomarkers, particularly through the detection of EV-associated non-coding RNAs, proteins, lipids, and other molecular signatures. However, methodological variability and limited clinical validation remain key barriers to clinical translation. Further preclinical and clinical studies are needed to establish the role of EVs in liquid biopsy and personalized targeted therapy for TC. This review provides a comprehensive and systematic overview of EVs in TC, with particular emphasis on methodological factors influencing EV research, including sample-specific isolation and characterization strategies. Based on a systematic literature survey, this review integrates current knowledge on EV-associated cargo, biological functions, biomarker and therapeutic potential while critically evaluating methodological challenges and outlining future directions for clinical translation.\n\nID: 42640395\nTitle: Exosomes in the treatment of age-related ophthalmic diseases: an updated review.\nAbstract: Exosomes are nanoscale extracellular vesicles of endosomal origin that mediate intercellular communication by transferring bioactive cargo, including proteins, lipids, messenger RNAs, microRNAs, and other regulatory molecules. Through this process, they can modulate the biological functions of recipient cells. Age-related ophthalmic diseases, including age-related macular degeneration (AMD), dry eye disease (DED), and age-related cataract (ARC), are degenerative ocular conditions whose incidence increases with age and are associated with chronic inflammation, oxidative stress, dysregulated angiogenesis, tissue fibrosis, epithelial injury, and apoptosis. Diabetic retinopathy (DR), although not classically defined as an age-related ophthalmic disease, is also briefly discussed in this review as an age-associated metabolic retinal comorbidity. Existing clinical treatments have several limitations, including the need for repeated administration, variable therapeutic responses, and potential adverse effects. Because of their biocompatibility, low immunogenicity, modifiable cargo and potential for local delivery, exosomes are being investigated as therapeutic agents and drug delivery vehicles in ophthalmology. This review summarizes the biological characteristics of exosomes and their potential relevance to ophthalmic applications, reviews recent evidence on their roles and mechanisms in major age-related ophthalmic diseases, and discusses the current limitations and future directions of exosome-based therapeutic strategies.\n\nID: 42633398\nTitle: Therapeutic potential and underlying mechanisms of engineered young plasma-derived exosomes in Alzheimer's disease.\nAbstract: Exosomes (EXOs) derived from the plasma of young individuals are believed to have the potential to ameliorate aging-related memory deficits. However, their specific roles and mechanisms in Alzheimer's disease (AD) therapy have not yet been systematically investigated. In this study, the rabies virus glycoprotein-targeting peptide (RVG-29) was conjugated to the surface of young plasma-derived EXOs to construct RVG-engineered EXOs (RVG-EXOs), and their therapeutic potential and underlying mechanisms in AD models were systematically evaluated. In 3\u00d7Tg AD model mice, exogenous administration of young plasma-derived EXOs and their engineered product (RVG-EXOs) revealed that RVG-EXOs could more efficiently enter brain tissue and target neurons, significantly reduce A\u03b2 plaque and phosphorylated Tau (P-Tau) pathological deposition, restore synaptic structure, promote neuronal survival, and improve cognitive behavior. Mechanistic studies demonstrated that RVG-EXOs inhibited RPTOR expression, thereby activating the autophagy pathway and promoting the clearance of pathological proteins. Both in vitro and in vivo experiments confirmed that overexpression of RPTOR significantly suppressed the therapeutic effects of RVG-EXOs. single-cell transcriptomic profiling further revealed that RVG-EXOs not only increased neuronal proportion and modulated excitatory/inhibitory neuronal balance but also reshaped the microglial landscape by reducing deleterious disease-associated while increasing homeostatic surveillant microglia. In summary, this study not only reveals for the first time the potential value of young plasma-derived EXOs in AD treatment but also, through RVG engineering strategies and the elucidation of the RPTOR-autophagy mechanism, provides new insights for targeted therapy of neurodegenerative diseases.\n\nID: 42625775\nTitle: Exosome-orchestrated network in gastric cancer: mechanisms, immune regulation, biomarkers and therapeutic vehicles.\nAbstract: Gastric cancer (GC) is a malignancy with high global incidence and mortality, and its poor prognosis and therapeutic failure are largely attributable to a complex tumor microenvironment. Extracellular vesicles (EVs) mediate intercellular molecular communication and are deeply involved in the initiation and progression of GC. Here, we focus on exosomes, the most thoroughly studied EV subtype (30-150\u00a0nm), and examine their biological roles in GC and their potential for clinical translation. We construct an exosome-derived molecular network of GC progression across six dimensions: promoting tumor cell proliferation, orchestrating an immunosuppressive microenvironment, inducing tumor angiogenesis, remodeling the extracellular matrix, guiding metastasis, and mediating drug resistance. In this review, we systematically summarize exosome-derived non-coding RNAs and proteins as biomarkers for early detection and prognosis of GC. Moreover, emerging strategies targeting exosomes or employing exosomes as delivery vehicles are discussed. Finally, we address current challenges in exosome research and propose future directions. This review aims to serve as a reference for basic research and clinical translation in GC, emphasizing that deciphering exosome-mediated intercellular dialogue is essential for understanding the molecular underpinnings of tumor progression and developing novel intervention strategies.\n\nID: 42572185\nTitle: Current Advances of Molecular Biomarkers and Liquid Biopsies Techniques in Ovarian Cancer.\nAbstract: Ovarian cancer (OC) remains a lethal gynecological malignancy with challenges in early diagnosis, treatment monitoring, and overcoming drug resistance. Liquid biopsy, a noninvasive approach analyzing tumor-derived components in bodily fluids, has emerged as a promising tool in OC management. This review summarizes advances in liquid biopsy technologies, focusing on circulating tumor DNA (ctDNA) and circulating tumor cells (CTCs). ctDNA enables minimally invasive assessment for diagnosis, prognosis, treatment guidance (e.g., BRCA1/2-targeted therapy), minimal residual disease (MRD) detection, and monitoring of tumor evolution. CTCs, particularly clusters, provide insights into metastasis and therapeutic response. Emerging modalities such as tumor-educated platelets (TEPs), circular RNAs (circRNAs), and exosomes and protease activity-based liquid biopsy also show diagnostic and prognostic potential. Despite technical challenges like standardization and sensitivity, liquid biopsy holds significant promise for personalized OC care, with ongoing efforts to translate these technologies into clinical practice.\n\nID: 42547642\nTitle: The Dual Roles of Microglia- and Astrocyte-Derived Exosomes in Cerebral Ischemia-Reperfusion Injury: from Intercellular Communication to Therapeutic Prospects.\nAbstract: Cerebral ischemia-reperfusion injury (CIRI) is a complex pathological process characterized by metabolic dysfunction, oxidative stress, neuroinflammation, and structural and functional alterations of the neurovascular unit (NVU). Across different studies, CIRI has been reported to be associated, to varying degrees, with neuronal injury and neurological dysfunction. Increasing evidence suggests that exosomes (EXOs) derived from glial cells, particularly microglia and astrocytes, play critical roles in mediating intercellular communication and regulating injury progression in CIRI. This review systematically summarizes the context-dependent and heterogeneous functions of glia-derived EXOs in CIRI. Microglia-derived EXOs exhibit diverse and context-dependent functions depending on the activation state of donor cells and the surrounding microenvironmental conditions. Under pro-inflammatory conditions, EXOs released from microglia may exacerbate inflammation by carrying cargo components such as circular RNAs (circRNAs) and pro-inflammatory proteins, whereas EXOs associated with reparative states may support tissue recovery through the delivery of functional non-coding RNAs. These cargo components may participate in pathological regulation through multiple signaling pathways. Among them, the nuclear receptor coactivator 4 (NCOA4) axis is associated with ferroptosis, ubiquitin-specific protease 14 (USP14) with proteostasis/apoptosis, and thioredoxin-interacting protein (TXNIP) with inflammasome activity, all of which have been linked to reduced neuronal injury and functional recovery. In addition, M2-type-derived EXOs may participate in the regulation of synaptic plasticity and axonal regeneration by modulating the plexin A2 (PLXNA2)/RhoA/ROCK2 signaling pathway. Astrocyte-derived EXOs (ATC-EXOs) further contribute to NVU regulation. A2-type-derived EXOs have been reported in multiple experimental models to be associated with reduced NLR family pyrin domain containing 3 (NLRP3) inflammasome activity and alterations in the PI3K/Akt and MAPK signaling pathways, accompanied by attenuated inflammatory responses and improved blood-brain barrier (BBB) integrity in these models. Some studies suggest that these effects may be related to the transition of microglial phenotypes toward reparative states; however, sufficient in vivo mechanistic evidence supporting their direct regulatory effects remains lacking. In contrast, neurotoxic astrocytes (A1)-derived EXOs exhibit limited or context-dependent effects. Importantly, exosome function is highly state-dependent and cannot be fully explained by simplified pro-inflammatory microglia anti-inflammatory microglia (M1/M2) or A1/A2 paradigms. Moreover, extracellular vesicle heterogeneity and methodological limitations remain major challenges. Despite promising therapeutic potential, including the ability to cross the BBB and enable multi-target regulation, significant barriers to clinical translation persist, such as delivery efficiency, biodistribution, and standardization. Overall, glia-derived EXOs represent a dynamic and multi-level regulatory system in CIRI and a promising platform for precision therapeutic strategies.\n\nID: 42530066\nTitle: FDX1 expression promotes DSF/Cu-induced cuproptosis in gastric cancer cells.\nAbstract: Gastric cancer (GC) is a prevalent malignant tumor that warrants the development of drugs and therapeutic targets. Cuproptosis has emerged as a promising mechanism by which to inhibit tumors because copper homeostasis disorders frequently occur in various malignancies. The combination of disulfiram (DSF) and copper ions (DSF/Cu) has been shown to have significant antitumor effects. This study utilized DSF/Cu to investigate the mechanism underlying cuproptosis in GC cells. GC cells were treated with DSF/Cu and protein sequencing was performed to screen for differentially expressed genes. The mechanism by which overexpressed FDX1 regulates cuproptosis and WDR43 expression was determined. Subsequently, how to improve the efficacy of DSF/Cu in the treatment of GC was studied in a mouse model of GC. DSF/Cu had a good therapeutic effect on promoting cuproptosis in GC cells. Protein sequencing revealed WDR43 as a downstream gene of FDX1. Increasing the expression of FDX1 enhanced the sensitivity of GC cells to copper treatment and inhibited the expression of WDR43, thereby exerting an antitumor effect. Furthermore, DSF/Cu was loaded into exosomes derived from natural killer (NK) cells to enhance the biological safety and tumor targeting of DSF/Cu and validate the inhibitory effect on GC both in vitro and in vivo. This study showed that DSF/Cu promoted cuproptosis and the expression of FDX1 affected cuproptosis sensitivity of GC. Moreover, the combination of NK cell exosomes with DSF/Cu improved the therapeutic effect of DSF/Cu, which helps to promote the targeted therapy of GC and improve clinical applicability.\n\nID: 42522799\nTitle: Oral Squamous Cell Carcinoma: A New Era in Molecular Mechanisms and Emerging Targeted Therapies.\nAbstract: Oral squamous cell carcinoma (OSCC), the most common oral cancer, presents a clinical challenge due to its complex tumor microenvironment (TME), dysregulated pathways, and poor prognosis. Current methods of diagnosing OSCC use liquid biopsy technologies (ctDNA/microRNAs/exosomes) instead of relying solely on traditional methods such as open surgical biopsy. Liquid biopsy technologies provide non-invasive ways to detect and monitor OSCC in early stages, compared with traditional open surgical biopsy methods. Treatment of OSCC currently relies on chemotherapeutics (cisplatin/5-FU), radiotherapy, and targeted agents (cetuximab). However, resistance is acquired due to TME remodelling (tumor microenvironment) and/or due to epithelial-mesenchymal transition (EMT) through processes such as ABC transporter efflux. This review elucidates key molecular mechanisms, including PD-L1-mediated immune evasion, PI3K/AKT/mTOR hyperactivation, EGFR overexpression, and NF-\u03baB-driven inflammation, which promote proliferation, metastasis, and therapy resistance. One area of study involves the use of nanotechnology to convert phytocompounds (medicinal plants) into therapeutic agents by embedding phytocompounds into nanoparticles created using green synthesis techniques. EPR (Enhanced Permeability and Retention), ligand functionalization for OSCC targeting, improved bioavailability, and reduced toxicity are all advantages that the aforementioned systems provide, offering an opportunity to synergistically develop new therapies with chemotherapeutics for overcoming resistance. While numerous preclinical studies demonstrate that these newly developed therapies show increased efficacy compared with current therapy options, further work is needed in areas such as standardization, scaling, and clinical translation. As such, the importance of developing pathway-informed diagnostic tests and developing therapies that exploit pathway-specific activity with phytocompounds is emphasized. In addition, large-scale studies should be considered to evaluate the effectiveness of a pathway-informed approach in assessing and differentiating OSCC and personalized therapy strategies, to improve OSCC survival outcomes.\n\nID: 42512321\nTitle: Routes of Cancer Dissemination: Distinguishing Lymphatic and Hematogenous Spread from Venous Entry to Systemic Arterial Distribution.\nAbstract: Background/Objectives: Cancer metastasis is responsible for most cancer-related deaths, yet the precise anatomical and physiological routes by which cancer cells disseminate remain incompletely defined. This review aims to present an integrated model of lymphatic and hematogenous dissemination that provides a unified framework for understanding metastatic progression. Methods: The published literature on lymphatic biology, microvascular physiology, tumor immunology, and cancer metastasis was critically reviewed and integrated to develop a comprehensive anatomical and physiological model of cancer dissemination. Results: The proposed model identifies lymphatic dissemination as the predominant metastatic route in many solid tumors. Cancer cells enter structurally permissive initial lymphatic capillaries and are transported to the sentinel lymph node (SLN), where interactions with the tumor microenvironment may eliminate disseminated cells, maintain dormancy, or facilitate immune escape and further dissemination. Cancer cells that survive within or escape beyond the SLN subsequently travel through collecting lymphatics and the thoracic or right lymphatic duct to enter the systemic venous circulation. Following cardiopulmonary transit, surviving cells may be redistributed through the systemic arterial circulation to distant organs. A secondary pathway involves direct hematogenous intravasation through post-capillary venules, where reduced shear stress, increased endothelial permeability, and permissive endothelial biology facilitate entry into the venous circulation. Thus, lymphatic and direct venular pathways ultimately converge in the venous circulation before systemic arterial dissemination. Conclusions: This unified model integrates lymphatic and hematogenous dissemination into a coherent anatomical and physiological framework. By emphasizing the SLN as an early immunologic checkpoint and the arterial circulation as the final distribution network for disseminated cancer cells, this review provides a conceptual basis for understanding metastatic patterns and identifying biomarkers and therapeutic vulnerabilities.\n\nID: 42511736\nTitle: Urinary Extracellular Vesicle-Derived miRNAs as Regulators and Biomarkers in Diabetic Kidney Disease.\nAbstract: Diabetic kidney disease (DKD) remains one of the most severe microvascular complications of type 2 diabetes mellitus (T2DM) and a leading cause of chronic kidney disease (CKD) worldwide. Nevertheless, despite considerable progress in elucidating its molecular background, early diagnosis and accurate stratification of disease progression remain challenging when relying on conventional clinical biomarkers such as albuminuria and estimated glomerular filtration rate (eGFR). Growing evidence indicates that DKD is driven by interconnected pathogenic mechanisms, including chronic hyperglycemia, activation of the protein kinase C (PKC) signaling pathway, renin-angiotensin-aldosterone system (RAAS) dysregulation, oxidative stress, inflammatory cascades, and immune system activation involving Toll-like receptors (TLR) and the NLRP3 inflammasome. These processes collectively contribute to endothelial dysfunction, podocyte injury, extracellular matrix accumulation, and progressive renal fibrosis. Exosomes and their molecular cargo, particularly miRNAs, have emerged as promising regulators and non-invasive biomarkers reflecting ongoing renal injury. Urinary exosomal microRNAs (uEV-miRNAs) are of interest due to their stability in biological fluids and their direct origin from nephron segments, enabling real-time reflection of renal pathophysiology. Accumulating studies suggest that differentially expressed microRNAs (miRNAs), including miR-21-5p, miR-30a-5p, miR-192-5p, and miR-142-3p, are closely associated with key pathways in DN. However, their clinical translation remains limited by methodological heterogeneity, the lack of standardized isolation protocols, and insufficient validation in large longitudinal cohorts. This review navigates the current landscape of knowledge on the molecular mechanisms underlying DKD and examines the emerging role of uEV-miRNAs as diagnostic biomarkers. Altogether, uEV-miRNAs offer a promising avenue for improving early detection, risk stratification, and disease monitoring in DKD.\n\nID: 42502396\nTitle: MZT2A drives epithelial-mesenchymal transition in lung adenocarcinoma via the LGALS3BP/ITGB1/TGF-\u03b2/smad2 axis.\nAbstract: The high mortality of lung adenocarcinoma (LUAD) is largely attributed to its metastatic propensity; therefore, elucidating novel mechanisms driving metastasis is crucial for developing diagnostic and therapeutic strategies. This study aimed to elucidate the function and mechanism of MZT2A in the metastasis of LUAD. Analysis of clinical samples and public databases revealed that MZT2A is highly expressed in LUAD tissues and significantly associated with lymph node metastasis, advanced stage, and poor prognosis. In vitro functional assays revealed that MZT2A overexpression significantly enhanced the invasion, migration, and adhesion of LUAD cells and induced epithelial-mesenchymal transition (EMT). Mechanistically, via its MOZART2 domain, MZT2A interacts with the SRCR domain of galectin-3-binding protein (LGALS3BP), promoting the sorting of LGALS3BP into exosomes and its subsequent secretion. Secretory LGALS3BP acts as a ligand, binding to integrin beta-1 (ITGB1) on the cell membrane through its BTB domain, thereby activating the downstream TGF-\u03b2/smad2 signaling pathway to drive EMT and metastatic phenotypes. Molecular docking and mutation experiments confirmed these critical domain interactions. In vivo experiments also validated that MZT2A overexpression promoted pulmonary metastasis, while LGALS3BP knockdown reversed this effect. Collectively, this study elucidated a novel \"MZT2A-LGALS3BP-ITGB1-TGF-\u03b2/smad2\" signaling axis that drives LUAD metastasis, providing a potential novel target for prognosis assessment and targeted therapy in LUAD.\n\nID: 42499024\nTitle: The intellectual structure and emerging trends on nanotechnology in inflammatory bowel disease: A bibliometric analysis from 2005 to 2024.\nAbstract: As a chronic inflammatory disease of the intestine, inflammatory bowel disease (IBD) is challenged by existing treatment methods, such as poor drug targeting, low bioavailability, and systemic toxicity. In recent years, nanotechnology has provided a new strategy for the treatment and diagnosis of IBD due to its advantages of precise delivery, controllable release and multifunctional integration. We searched the Web of Science Core Collection database for relevant literature about nanotechnology and IBD published from 2005 to 2024. We used SciExplorer, VOSviewer, and Citespace to analyze countries, institutions, authors, keywords, highly cited references, and co-cited references to discuss research hotspots and trends in this field. The research analysis included a total of 959 pieces of literature, with China and the USA leading in the number of papers published and academic influence. The Georgia State University had the most papers posted. Merlin Didier and Xiao Bo were the scholars who published the most. The research hotspots mainly focus on nanodrug delivery systems, targeted therapy and inflammation regulation, while exosomes, macrophage polarization, and intestinal microbiota regulation are becoming new research frontiers. In the future, intelligent responsive nanomaterials, multifunctional nanoplatforms, and personalized nanotechnology will become important development directions. A new avenue for the accurate diagnosis and treatment of IBD has been unlocked by nanotechnology, but its clinical translation needs to break through the bottlenecks of biocompatibility, large-scale preparation and interdisciplinary collaboration. In the future, we should focus on the development of \"intelligent responsive nanosystems,\" deepen the research on the interaction mechanism of \"nano-microbe-host,\" and promote the establishment of a personalized treatment system.\n\nID: 42475384\nTitle: Exosomal gene-based predictive model and therapeutic target identification for Alzheimer's disease: A bioinformatics analysis.\nAbstract: Alzheimer's disease (AD) is a degenerative central nervous system disorder characterized by progressive cognitive and behavioral impairment. As nanoscale intercellular communication vesicles that carry AD-related pathological molecules, exosomes are promising biomarkers and therapeutic carriers for AD. In this study, we downloaded AD-related gene expression profiles and clinical data from the Gene Expression Omnibus (GEO) database (datasets GSE138260, GSE29378, GSE36980, and GSE5281). Through a series of bioinformatics analyses, clinical predictive model construction, pharmacological network analysis, and molecular docking simulations, we developed an exosomal gene-based predictive model for AD pathogenesis and identified potential pharmacological networks and molecular docking targets for AD treatment. AD-related gene expression and clinical data were retrieved from the GEO database. Bioinformatics analyses, clinical model construction, drug-gene network analysis, and molecular docking were subsequently performed to explore exosomal gene models for predicting AD pathogenesis, as well as potential pharmacological networks and molecular docking targets for AD therapy. A five-exosomal-gene predictive model was established, comprising CD44, CXCR4, TUBB, PSMA5, and PSMB3. Pharmacological network analysis of these five genes revealed their significant associations with chelidonine, 2-chloro-1,4-dinitrobenzene, oxazolone, phencyclidine, thioridazine, and etodolac. Further molecular docking simulations identified key binding targets, including R41, Y42, R78, Y79, C77, I88, C97, A98, I96, I72, L70, E67, G103, I91, and T102. Our comprehensive analyses successfully established a reliable exosomal gene-based model for predicting AD pathogenesis, and identified relevant pharmacological networks and core molecular docking targets, providing novel insights for AD diagnosis and targeted therapy.\n\nID: 42458565\nTitle: Epigenetic modulation of the JAK2-STAT3 signaling pathway in osteoporosis: non-coding RNA networks as therapeutic targets.\nAbstract: Osteoporosis, a prevalent metabolic bone disease affects over 200 million people worldwide and is associated with an elevated fracture risk, is characterized by an imbalance between bone resorption and formation. The JAK2-STAT3 signaling pathway serves as a critical regulator of bone remodeling, but its chronic activation contributes to pathological bone metabolism in osteoporosis. Understanding the precise regulation of this pathway is essential for developing novel therapies. Our review reveals that specific miRNAs directly target components of the JAK2-STAT3 pathway (e.g. JAK2, STAT3, SOCS) to fine-tune osteoblast and osteoclast activity. This regulatory network is further expanded by lncRNAs and circRNAs, which act as competitive endogenous RNAs (ceRNAs) or \"molecular sponges\" to sequester miRNAs, thereby indirectly modulating JAK2-STAT3 signaling. This multi-tiered ncRNA network influences key processes such as osteogenic differentiation, inflammatory response and mitochondrial redox homeostasis, ultimately determining bone metabolic balance. The ncRNA network represents a promising therapeutic target for bone-related and metabolic diseases, especially osteoporosis, through its precise control over the JAK2-STAT3 pathway. Targeting these ncRNAs, potentially via engineered exosomes or biomaterial-based delivery systems, offers a novel and different strategy for restoring bone homeostasis, paving the way for future precision medicine in bone metabolic diseases.\n\nID: 42454189\nTitle: Research on exosomes in cancer multidrug resistance and clinical translation.\nAbstract: Multidrug resistance (MDR) is a major clinical challenge that limits the efficacy of multiple cancer treatment modalities, including chemotherapy, targeted therapy, immunotherapy, monoclonal antibody therapy, and antibody-drug conjugates. In recent years, exosomes (Exos), nanoscale vesicles involved in intercellular communication, have attracted increasing attention for their roles in the formation and spread of MDR. A growing body of evidence suggests that Exos mediate the transfer of resistance-related molecular signals among drug-resistant cancer cells, drug-sensitive cancer cells, and stromal cells, such as cancer-associated fibroblasts and tumor-associated macrophages, through the selective packaging of noncoding RNAs, functional proteins, and metabolic regulators. These molecular signals may induce the reprogramming of signaling pathways, metabolism, and epigenetic states in recipient cells, thereby promoting the acquisition of cancer stem cell-like properties and a drug-resistant phenotype. In turn, these changes may contribute to the establishment of a drug resistance-supporting tumor microenvironment. This review systematically summarizes the molecular mechanisms by which Exos contribute to multidrug resistance, with a particular focus on their roles in cargo sorting, microenvironmental crosstalk, and the functional reprogramming of recipient cells. It also discusses their potential for clinical translation in resistance monitoring and reversal therapy. In addition, this review further discusses the key challenges currently facing the field and provides perspectives on future research directions.\n\nID: 42448218\nTitle: Targeting soluble PD-1 alleviates peritoneal fibrosis by modulating PD-L1 recycling and mesothelial-mesenchymal transition.\nAbstract: Peritoneal fibrosis (PF) is a major cause of technique failure in long-term peritoneal dialysis (PD) patients, driven by a chronic microinflammatory state. While T-cell activation is implicated, the role of soluble programmed death-1 (sPD-1), primarily derived from activated T cells, in PF pathogenesis remains elusive. We initially analyzed serum sPD-1 levels in PD patients and employed a mice PF model induced by high-glucose dialysate and lipopolysaccharide (LPS). The functional impact of sPD-1 on the progression of PF was assessed through the administration of a PD-L1 fusion protein, or engineered exosomes designed to adsorb sPD-1. Serum sPD-1 levels were significantly elevated in long-term PD patients and were positively correlated with dialysis duration and markers of fibrosis, but inversely correlating with peritoneal function. In mice, exogenous sPD-1 exacerbated PF, whereas blockade with a PD-L1 fusion protein or sPD-1-adsorbing engineered exosomes markedly attenuated fibrosis, reduced T-cell infiltration, and preserved peritoneal function. Mechanistically, sPD-1 bound to PD-L1 on PMCs, triggering clathrin-mediated endocytosis. This interaction diverted PD-L1 from the lysosomal degradation pathway towards the Rab11-positive recycling endosome pathway, resulting in sustained upregulation of surface PD-L1 expression. This aberrant PD-L1 recycling activated pro-fibrotic signaling, culminating in mesothelial-to-mesenchymal transition (MMT). sPD-1 is a pivotal mediator linking peritoneal microinflammation to fibrosis by modulating the endocytic fate of PD-L1 in mesothelial cells. Targeting sPD-1, particularly using engineered exosomes or a PD-L1 fusion protein, represents a promising therapeutic strategy for preventing and treating peritoneal fibrosis.\n\nID: 42445823\nTitle: Bioengineered Exosome-Magnetic Nanoplatform for Precision Therapy of Hepatocellular Carcinoma via Dual-Targeted Drug Delivery.\nAbstract: Hepatocellular carcinoma (HCC) continues to pose a significant threat to global health, contributing substantially to worldwide cancer-related mortality, particularly in high-incidence regions such as Asia, where current treatment strategies are often limited by poor drug delivery efficiency, systemic toxicity, and drug resistance. To address these critical challenges, we developed an innovative dual-targeted nanoplatform (Exo-SPIONs-SRF/CGA) that synergistically combines the natural tumour-homing capability of HCC-derived exosomes with the magnetic guidance of superparamagnetic iron oxide nanoparticles (SPIONs) for precision drug targeting. This nanoplatform co-encapsulates SRF and CGA to improve the therapeutic index by enhancing desired responses and minimizing undesired side effects. The exosome component provides inherent biological targeting to HCC cells. At the same time, the incorporated SPIONs enable external magnetic field-guided spatial control, collectively ensuring superior tumour accumulation compared to conventional delivery systems. Furthermore, the platform's tumour microenvironment-responsive release characteristics ensure localized drug activation, maximizing the therapeutic index through spatial and temporal control of drug availability. In vitro and in vivo evaluations demonstrated that this nanoplatform significantly enhances tumour suppression and drug retention while reducing systemic side effects compared to monotherapies or single-modality nanocarriers. The Exo-SPIONs-SRF/CGA platform represents a promising strategy in HCC treatment, addressing fundamental limitations of current therapies by simultaneously overcoming biological barriers to drug delivery, enhancing therapeutic efficacy through synergistic drug combinations, and minimizing collateral damage to healthy tissues, thereby advancing the frontier of precision oncology toward more effective and safer HCC management.\n\nID: 42424986\nTitle: Lymphatic extracellular vesicles and non-coding rnas in the melanoma sentinel lymph node pre-metastatic niche: Emerging lessons from aggressive skin cancers.\nAbstract: Sentinel lymph node (SLN) involvement remains one of the strongest prognostic markers in cutaneous melanoma; however, the SLN is not merely a staging specimen. It is the first organized immune-stromal site exposed to lymph-borne melanoma-derived extracellular vesicles (EVs), soluble mediators, proteins, lipids, and non-coding RNAs (ncRNAs) before and during metastatic seeding. Current evidence supports a model in which melanoma-derived EVs traffic through lymphatic vessels, enter draining nodes, interact with lymphatic endothelial cells, medullary macrophages, dendritic cells, and T cells, and remodel lymphovascular, stromal, and immune compartments. Key vesicle-associated mechanisms include NGFR/p75NTR-positive small extracellular vesicles (sEVs) that drive lymphangiogenesis and nodal metastasis, PD-L1-positive vesicles that suppress T-cell activation, CD36-linked pathways that reshape myeloid lipid metabolism, and uPAR-associated vesicles that promote endothelial and matrix remodeling. EV-associated miRNAs, lncRNAs, and circRNAs may further regulate fibroblast activation, macrophage behavior, MAPK/ERK signaling, PTEN-related stromal restraint, glycolysis, autophagy, and tumor-suppressive pathways. This review integrates clinical SLN biology, lymphatic vesicle trafficking, cargo-specific protein and ncRNA pathways, immune tolerance, stromal remodeling, multi-omic profiling, and therapeutic interception. Comparative evidence from cutaneous squamous cell carcinoma and Merkel cell carcinoma broadens the field, but direct evidence linking lymphatic EVs to SLN remodeling remains strongest in melanoma.\n\nID: 42360611\nTitle: Mannose receptor-targeted MSC-derived exosomes as a high-affinity delivery platform for liver sinusoidal endothelial cells.\nAbstract: Liver sinusoidal endothelial cells (LSECs) play a crucial role in the progression of liver fibrosis. While mesenchymal stem cell-derived exosomes (MSC-Exos) hold potential for liver regeneration, their therapeutic efficacy is often limited by poor target specificity and rapid clearance. Here, we developed mannose receptor-targeting MSC-Exos (Man-Exos) by incorporating DSPE-PEG-Mannose via a post-insertion method to enhance LSEC-specific delivery. The physicochemical stability and targeting efficiency of Man-Exos were evaluated both in vitro and in vivo. Man-Exos exhibited high stability in various conditions and showed significantly enhanced binding affinity to LSECs compared to non-targeted exosomes. Notably, in a co-culture system of LSECs and macrophages, Man-Exos demonstrated superior selectivity for LSECs. In vivo biodistribution studies further confirmed that Man-Exos predominantly accumulated in the liver, specifically colocalizing with LSECs for up to 48\u2009h. Our findings suggest that Man-Exos can serve as a highly efficient and stable delivery platform for LSEC-targeted therapy, providing a promising strategy for enhancing the translational potential of exosome-based regenerative medicine in liver fibrosis.\n\nID: 42357492\nTitle: Advances in Nano-Drug Delivery Systems for Chronic Autoimmune Diseases: A Focus on Diabetes Mellitus, Inflammatory Bowel Disease, and Rheumatoid Arthritis.\nAbstract: The global prevalence of autoimmune diseases ranges from 3% to 8%, with women at a significantly higher risk than men. The core mechanisms underlying these diseases include impaired T-cell and B-cell immune tolerance, abnormal cytokine production, and aberrant activation of related signaling pathways. Conventional treatments primarily focus on suppressing immune responses, but their efficacy remains limited and they are often associated with substantial side effects. Nanomedicine leverages nanoscale materials to enable precise diagnosis and targeted therapy. Nanocarriers can penetrate biological barriers, enhance cellular uptake, and prolong circulation time in vivo, demonstrating considerable potential for drug delivery. Common nanoscale drug delivery platforms include nanoparticles, polymeric micelles, liposomes, dendrimers, mesoporous materials, hydrogels, and exosomes. Each carrier type possesses distinct characteristics in terms of drug-loading capacity, stability, responsiveness, and biocompatibility, thereby enabling targeted delivery and controlled release. This review summarizes recent advances in nano-delivery technologies for three representative chronic autoimmune diseases: diabetes mellitus (DM), inflammatory bowel disease (IBD), and rheumatoid arthritis (RA). Nano-delivery systems can improve therapeutic outcomes by optimizing drug delivery, targeting complications, and modulating the pathological microenvironment. They enhance drug bioavailability, reduce off-target and systemic adverse effects, and provide novel strategies for the precise and efficient treatment of chronic autoimmune diseases.\n\nID: 42353096\nTitle: 17-DMAG-Loaded HER2-Targeted Extracellular Vesicles Induce PARP/Caspase3-Mediated Apoptosis in Gastric Carcinoma.\nAbstract: Gastric cancer remains a major clinical challenge, underscoring the need for more effective drug delivery strategies. Approximately 10-20% of gastric cancers overexpress HER2, conferring aggressive tumor characteristics and poor survival, yet resistance to trastuzumab-based targeted therapy and limited intratumoral antibody penetration continue to restrict clinical outcomes. This study evaluated HER2-targeted exosomes as a delivery platform. Exosomes were engineered to express the p51 peptide, a high-affinity HER2-binding ligand, and loaded with 17-dimethylaminoethylamino-17-demethoxygeldanamycin (17-DMAG), a potent HSP90 inhibitor. The cellular uptake and antitumor efficacy of p51-Exo17-DMAG were assessed in vitro using NCI-N87 and AGS cells and in vivo using a mouse xenograft model. p51-modified exosomes exhibited superior HER2 specific uptake. Treatment with p51-Exo17-DMAG significantly increased apoptosis, as demonstrated by elevated PARP and caspase3 cleavage, and downregulated oncogenic signaling molecules, including p-AKT, CDK2, VEGF, and c-Myc. Furthermore, p51-Exo17-DMAG increased the number of TUNEL-positive cells. In the NCI-N87 xenograft model, systemic administration of p51-Exo17-DMAG significantly inhibited tumor growth without toxicity or histological damage to major organs. Tumor analysis confirmed increased apoptosis and reduced proliferation in vivo. These findings demonstrate that p51-engineered exosomes provide an efficient, selective, and safe platform for HER2-targeted delivery of 17-DMAG, offering a promising precision medicine strategy for HER2-positive gastric cancer.\n\nID: 42341587\nTitle: Innovations in peptide-based targeted therapies for breast cancer: From conjugates to precision delivery.\nAbstract: Breast cancer remains a leading cause of mortality among women worldwide, necessitating therapeutic innovations that combine precision targeting with effective delivery. Peptides have emerged as versatile tools in breast cancer-targeted therapy, functioning as tumor-targeting ligands, vaccine epitopes, and delivery enhancers across various platforms, including exosomes, nanoparticles, drug conjugates, and engineered immune cells. These multifunctional systems address limitations of conventional breast cancer therapies by leveraging the inherent specificity and adaptability of peptides to enable precise drug delivery, disrupt oncogenic signaling pathways, modulate the tumor microenvironment, and overcome therapeutic resistance. This review presents recent advances in peptide-based targeted therapies, highlighting the ongoing need to address tumor heterogeneity and resistance.\n\nID: 42341362\nTitle: Synergistic \"targeting and blockade\" strategy via engineered exosomes and clinical ultrasound contrast agent for hepatocyte-targeted mRNA delivery.\nAbstract: Homozygous familial hypercholesterolemia (HoFH) presents a persistent and difficult-to-treat condition. This recalcitrance stems largely from loss-of-function mutations within the low-density lipoprotein receptor (LDLR) gene, which severely undermine the efficacy of standard therapeutic regimens. Here, we report a bioinspired \"targeting and blockade\" strategy for the efficient delivery of functional Ldlr mRNA to hepatocytes. This approach is realized through a rationally designed platform, Szd\u00a0+\u00a0AP@ExoE-Ldlr, which integrates APOA1-functionalized exosomes for hepatocyte-targeted delivery with a preemptive macrophage blockade using the clinical ultrasound contrast agent Sonazoid (Szd). The APOA1 modification confers specific recognition by the scavenger receptor class B type 1 on hepatocytes, while the pre-saturation of Kupffer cells with Szd significantly mitigates nonspecific clearance by the mononuclear phagocyte system (MPS). In a HoFH murine model, this synergistic strategy markedly enhanced the accumulation of exosomes in hepatocytes and achieved robust restoration of hepatic LDLR expression. Consequently, it elicited a profound correction of the atherogenic lipid profile and substantially attenuated the progression of atherosclerosis. A comprehensive biosafety evaluation confirmed the excellent biocompatibility of this platform. Our work provides a promising and broadly applicable solution for the treatment of liver-related genetic disorders by simultaneously overcoming the critical barriers of targeted delivery and MPS evasion.\n\nID: 42337603\nTitle: iRGD-modified 3D exosomes delivered miR-99b-5p induces ferroptosis to inhibit colorectal cancer progression by regulating FGFR3/PI3K/AKt pathway.\nAbstract: Mesenchymal stem cells (MSCs)-derived exosomes present great potential as nanocarriers for targeted drug delivery. Moreover, the therapeutic efficacy of exosomes can be substantially enhanced through functional modifications and the incorporation of bioactive molecules. In this study, the MSCs were cultured under two-dimensional (2D) and three-dimensional (3D) cell culture conditions. The culture supernatants were collected for isolating exosomes. The characteristics and yields of exosomes from 2D and 3D cultures were detected by nanoparticle tracking analysis (NTA), transmission electron microscopy (TEM), western blot analysis, and bicinchoninic acid (BCA) assay. Subsequently, 3D exosomes were loaded with miR-99b-5p and modified with iRGD peptide were formed into a new engineered exosome, designated as iRGD-Exo-miR-99b-5p. The effects of these engineered exosomes on the progression of colorectal cancer (CRC) were assessed through a series of in vivo and in vitro experiments. The 3D-cultured MSCs exhibited a higher yield of exosomes and enhanced uptake by CRC cells. Further in vitro experiments demonstrated that 3D-exosomes loaded with miR-99b-5p effectively inhibit the proliferation, invasion, migration and epithelial-mesenchymal transition (EMT) of CRC cells. Results from a xenograft tumor model indicate that iRGD-modified exosomes were significantly enriched at tumor sites. Furthermore, exosomes modified with iRGD and loaded with miR-99b-5p were employed for CRC treatment, resulting in substantial tumor growth inhibition and enhanced the chemotherapy efficacy of 5-fluorouracil (5-FU) in vivo, without inducing notable toxicity or side effects. Mechanistically, exosome-mediated delivery of miR-99b-5p downregulated FGFR3 expression, thereby inhibiting the activation of the PI3K/AKt signaling pathway and promoting ferroptosis, ultimately attenuating CRC progression. Collectively, iRGD-modified 3D exosomes loaded with miR-99b-5p were able to specifically target tumor sites, thereby significantly suppressing CRC growth through the induction of ferroptosis via regulating the FGFR3/PI3K/AKt signaling pathway. These findings suggest that functional engineering and bioactive loading of 3D-exosomes derived from MSCs represent a promising strategy for targeted cancer therapy.\n\nID: 42327493\nTitle: Exercise-derived exosomal miR-151-3p: An innovative anti-inflammatory and antioxidant therapeutic for spinal cord injury.\nAbstract: Exercise (Exe) training is a cornerstone of multimodal rehabilitation of patients with spinal cord injury (SCI), yet the precise mechanisms through which it exerts its therapeutic benefits remain unclear. Exosomes (Exos) are key mediators of intercellular communication and promising vehicles for targeted therapy. This study aimed to investigate the function and underlying mechanism of exercise-derived exosomes (Exe-Exos) in SCI recovery. Circulating Exos were isolated from rats subjected to a 4-week treadmill Exe regimen and from sedentary controls. A gelatin methacrylate (GelMA) hydrogel microneedles (Hyd MNs) system was developed for the targeted, sustained delivery of these Exos directly to the injury epicenter at the T10 spinal segment in a rat SCI model. Using integrated in vitro and in vivo approaches, we showed that Exe-Exos significantly promoted motor function recovery, attenuated tissue damage, reduced apoptosis, and alleviated both inflammation and oxidative stress (Oxs) after SCI. Small RNA sequencing revealed that miR-151-3p is a key functional cargo that is enriched in Exe-Exos. Gain- and loss-of-function studies revealed that exosomal miR-151-3p exerts its protective effects by directly targeting the mitochondrial membrane protein ROMO1. This targeting led to the coordinated inhibition of the pro-apoptotic JNK/Caspase pathway, suppression of the NF-\u03baB-mediated inflammatory cascade, and activation of the Nrf2/HO-1 antioxidant axis. Collectively, our findings establish Exe-Exos, specifically exosomal miR-151-3p, as an exercise-responsive circulating signaling axis that orchestrates multifaceted protection against secondary injury after SCI, offering an innovative, mechanism-based strategy for neuroregenerative therapy.\n\nID: 42321780\nTitle: Biomimetic fusion nanosystem from ginger exosomes and tumor cell membranes: boosting PLK1-targeted therapy in BRCA-heterogeneous HGSOC.\nAbstract: High-grade serous ovarian carcinoma (HGSOC) remains a lethal malignancy with few effective therapeutic options. In this study, we systematically evaluated the anti-tumor effect of Bi2536, an inhibitor of Polo-like kinase 1 (PLK1), in HGSOC, and clarified its mechanism. Bi2536 inactivates PLK1, leading to the subsequent inactivation of cyclin-dependent kinase 1 (CDK1). This disruption triggers a cascade of antitumor effects, including G2/M phase arrest, induction of mitochondrial apoptosis, and suppression of cell migration and invasion. Furthermore, we identified circadian oscillations in PLK1 expression both in HGSOC cells and in vivo xenograft models. To enhance therapeutic precision and minimize systemic toxicity, we engineered a biomimetic nano-delivery system for Bi2536. This integrated platform combines chemotherapy and chemodynamic therapy (CDT), significantly improving antitumor outcomes. Importantly, synchronizing Bi2536 administration with the circadian peaks of PLK1 expression further augmented its therapeutic efficacy. In summary, our work establishes that the combination of Bi2536 with a biomimetic nano-delivery system, together with its chronotherapeutic administration, constitutes a highly promising and multifaceted strategy for the treatment of HGSOC.\n\nID: 42320128\nTitle: Microfluidic capture and spatiotemporal analysis: Chemical mechanisms of tumor exosome-mediated malignant cell transformation.\nAbstract: Tumor metastasis is the primary cause of death from malignant tumors. The elucidation of its molecular mechanism is of great significance for breakthroughs in targeted therapy. In this study, a microfluidic chip platform integrating \"dynamic dilution-precise capture-mechanical stimulation-in situ analysis\" was constructed. Through the design of bionic narrow channels, efficient separation of exosomes and functional research at the single-cell level were achieved. On the one hand, the mechanical microenvironment within the chip was utilized to regulate the secretion of tumor cell exosomes (increasing secretion levels by more than twofold) and the expression of key proteins, revealing the exosome-mediated cell invasion behavior. On the other hand, using breast cancer as a model, the malignant transformation effects of exosomes derived from highly metastatic MDA-MB-231\u202fcells and low-metastatic MCF-7\u202fcells on normal MCF-10A breast epithelial cells were comparatively analyzed. The transformation efficiency was preliminarily verified using the CD43 (a marker associated with malignant transformation), and the reasonable inference was established regarding the regulatory role of PD-L1 in the epithelial-mesenchymal transition (EMT) process. Experiments were then conducted on whole blood samples (processing time for 0.5\u202fmL whole blood <10\u202fmin). The study provides new potential targets and intervention strategies for cancer immunotherapy.\n\nID: 42319605\nTitle: Identification and validation of exosome-related biomarkers in pediatric glioblastoma.\nAbstract: Pediatric glioblastoma (pGBM) is an aggressive central nervous system (CNS) tumor whose pathological progression is significantly influenced by exosomal signaling. This study integrated and analyzed transcriptomic datasets (GSE50161, GSE35493) from the Gene Expression Omnibus (GEO), focusing on the intersection between exosome-related genes (ERGs) and disease-associated differentially expressed genes (DEGs). Key biomarkers, FGF9, TGFBR1, and PLCB4, were identified using a machine learning model. The results demonstrated that TGFBR1 expression was up-regulated in the tumor microenvironment, whereas FGF9 and PLCB4 were down-regulated. These genes were closely associated with the \u03b3/\u03b1 (IFN-\u03b3/\u03b1) signaling pathway and E2F target activation. Immune profiling revealed that low expression of FGF9 and PLCB4 correlated with a reduction in central memory CD4+T cells, while high TGFBR1 expression was associated with an increase in memory B cells. Further regulatory network analysis uncovered potential epigenetic regulatory mechanisms. In silico drug screening and molecular docking suggested that the histone deacetylase inhibitor Trichostatin A may hold therapeutic potential. This study provides novel biomarkers and insights for the diagnosis and targeted therapy of pGBM.\n\nID: 42316572\nTitle: Extracellular Vesicles and Their Multifaceted Roles in Cancer: Current Evidence from a Narrative Review.\nAbstract: Extracellular Vesicles (EVs), including exosomes and microvesicles, are nanoscale, lipid bilayer-enclosed particles released by diverse cell types. They play a key role in intercellular communication by transferring proteins, lipids, and nucleic acids. In cancer, EVs contribute to remodelling the tumor microenvironment, enhancing angiogenesis, modulating immune responses, promoting metastasis, and driving therapeutic resistance. This narrative review aims to highlight the biological importance and clinical relevance of EVs in cancer, focusing on their potential as biomarkers and therapeutic tools. A comprehensive literature search was conducted using PubMed, Scopus, and Web of Science. Studies on EV composition, isolation, and characterization methods, as well as recent advances in EV bioengineering, were critically examined to summarize their significance in oncology. Findings reveal that the molecular cargo of EVs reflects the physiological and pathological states of their source cells, supporting their role as non-invasive biomarkers for cancer detection and monitoring. EVs also regulate signaling pathways that sustain tumor heterogeneity and adaptability. Moreover, engineered EVs demonstrate strong potential as delivery systems for chemotherapeutic agents, RNA-based drugs, and immunomodulators, underscoring their translational value in targeted therapy. EVs represent versatile tools in precision oncology. Although standardization and clinical validation remain challenges, ongoing research and technological progress may establish EV-based strategies as integral components of personalized cancer treatment.\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.

Moreover, the therapeutic efficacy of exosomes can be substantially enhanced through functional modifications and the incorporation of bioactive molecules. In this study, the MSCs were cultured under two-dimensional (2D) and three-dimensional (3D) cell culture conditions. The culture supernatants were collected for isolating exosomes. The characteristics and yields of exosomes from 2D and 3D cultures were detected by nanoparticle tracking analysis (NTA), transmission electron microscopy (TEM), western blot analysis, and bicinchoninic acid (BCA) assay. Subsequently, 3D exosomes were loaded with miR-99b-5p and modified with iRGD peptide were formed into a new engineered exosome, designated as iRGD-Exo-miR-99b-5p. The effects of these engineered exosomes on the progression of colorectal cancer (CRC) were assessed through a series of in vivo and in vitro experiments. The 3D-cultured MSCs exhibited a higher yield of exosomes and enhanced uptake by CRC cells. Further in vitro experiments demonstrated that 3D-exosomes loaded with miR-99b-5p effectively inhibit the proliferation, invasion, migration and epithelial-mesenchymal transition (EMT) of CRC cells. Results from a xenograft tumor model indicate that iRGD-modified exosomes were significantly enriched at tumor sites. Furthermore, exosomes modified with iRGD and loaded with miR-99b-5p were employed for CRC treatment, resulting in substantial tumor growth inhibition and enhanced the chemotherapy efficacy of 5-fluorouracil (5-FU) in vivo, without inducing notable toxicity or side effects. Mechanistically, exosome-mediated delivery of miR-99b-5p downregulated FGFR3 expression, thereby inhibiting the activation of the PI3K/AKt signaling pathway and promoting ferroptosis, ultimately attenuating CRC progression. Collectively, iRGD-modified 3D exosomes loaded with miR-99b-5p were able to specifically target tumor sites, thereby significantly suppressing CRC growth through the induction of ferroptosis via regulating the FGFR3/PI3K/AKt signaling pathway. These findings suggest that functional engineering and bioactive loading of 3D-exosomes derived from MSCs represent a promising strategy for targeted cancer therapy.\n --- END ACTUAL ABSTRACT FOR 42337603 ---\n\n- ERROR: You cited ID: 42579394 for the quote: \"Specifically, we fabricated FGF1-loaded exosomes functionalized with the rabies virus glycoprotein (RVG) peptide (FGF1-RVG Exo).

However, the blood-brain barrier (BBB) remains a formidable obstacle, restricting the delivery of most therapeutic molecules. To address this, we developed a non-invasive treatment strategy using engineered exosomes. Specifically, we fabricated FGF1-loaded exosomes functionalized with the rabies virus glycoprotein (RVG) peptide (FGF1-RVG Exo). This platform facilitates selective, neuron-targeted delivery of FGF1 to the ischemic penumbra via RVG-mediated transcytosis. In a diabetic stroke mouse model, FGF1-RVG Exo exhibited superior pharmacological efficacy compared to free FGF1, achieving robust therapeutic outcomes with only once-weekly administration. Notably, a single dose during the acute phase elicited a sustained hypoglycemic effect lasting up to two weeks and effectively ameliorated systemic insulin resistance. Locally, the accumulation of exosomes within the lesion led to a significant reduction in infarct volume and cell apoptosis, while promoting neovascularization and the recovery of motor and cognitive functions. This brain-targeted strategy achieves a peripheral-central synergistic modulation, addressing the multi-target requirements of diabetic stroke management. Collectively, our findings provide a novel paradigm for treating diabetic ischemic stroke and a potent strategy for the targeted delivery of growth factors to the central nervous system.\n --- END ACTUAL ABSTRACT FOR 42579394 ---\n\n- ERROR: You cited ID: 42576909 for the quote: \"The Cu/Zn bimetallic core, functionalized with a chimeric mitochondrial targeting peptide, serves as both a pH-responsive copper reservoir and a dual-enzyme mimetic.\"\n FACT: Strict Misquote Detected!

Cuproptosis, a non-apoptotic cell death modality, has emerged as a promising alternative, yet its therapeutic efficacy is frequently limited by robust intracellular antioxidant defense systems. Here, we developed an ultrasmall (ca.10\u202fnm) mitochondria-targeted bimetallic nanozyme (RMOCZ) for synergistic ferroptosis-cuproptosis therapy against malignant melanoma. The Cu/Zn bimetallic core, functionalized with a chimeric mitochondrial targeting peptide, serves as both a pH-responsive copper reservoir and a dual-enzyme mimetic (peroxidase and glutathione oxidase). Upon endolysosomal acidification, RMOCZ disassembles to co-release copper ions and oridonin (ORI). The nanozyme oxidizes intracellular glutathione (GSH), a process significantly accelerated by co-delivered ORI. This disruption of redox homeostasis not only triggers ferroptosis by compromising cellular antioxidant capacity but also amplifies peroxidase-mediated reactive oxygen species (ROS) production, sensitizing tumor cells to copper-induced cytotoxicity. Concurrently, RMOCZ induces ferritinophagy to mobilize the endogenous labile iron pool and exacerbate lipid peroxidation. These events culminate in sustained copper-iron dual-ion overload. Following subsequent mitochondrial trafficking, the accumulated copper ions trigger canonical cuproptotic events, including the degradation of iron-sulfur (Fe-S) clusters and aberrant oligomerization of lipoylated DLAT. This irreversible mitochondrial dysfunction triggers potent immunogenic cell death (ICD) with robust damage-associated molecular patterns (DAMPs) release. In situ immunohistochemical analyses confirm that this RMOCZ-induced ICD profoundly remodels the immunosuppressive microenvironment, promoting CD86+ antigen-presenting cell maturation and enhancing intratumoral infiltration of CD3+ and CD8+ T cells. In vivo, RMOCZ demonstrates substantial melanoma regression with negligible systemic toxicity, providing a promising strategy for treating apoptosis-resistant refractory malignancies.\n --- END ACTUAL ABSTRACT FOR 42576909 ---\n\n- ERROR: You cited ID: 42633397 for the quote: \"Their synergistic and complementary effects not only address key technical challenges associated with exosome delivery-such as low delivery efficiency and limited tissue penetration-but also endow MNs with capabilities for targeted therapy and precise diagnostics.\"\n FACT: Strict Misquote Detected!

The JAK2-STAT3 signaling pathway serves as a critical regulator of bone remodeling, but its chronic activation contributes to pathological bone metabolism in osteoporosis. Understanding the precise regulation of this pathway is essential for developing novel therapies. Our review reveals that specific miRNAs directly target components of the JAK2-STAT3 pathway (e.g. JAK2, STAT3, SOCS) to fine-tune osteoblast and osteoclast activity. This regulatory network is further expanded by lncRNAs and circRNAs, which act as competitive endogenous RNAs (ceRNAs) or \"molecular sponges\" to sequester miRNAs, thereby indirectly modulating JAK2-STAT3 signaling. This multi-tiered ncRNA network influences key processes such as osteogenic differentiation, inflammatory response and mitochondrial redox homeostasis, ultimately determining bone metabolic balance. The ncRNA network represents a promising therapeutic target for bone-related and metabolic diseases, especially osteoporosis, through its precise control over the JAK2-STAT3 pathway. Targeting these ncRNAs, potentially via engineered exosomes or biomaterial-based delivery systems, offers a novel and different strategy for restoring bone homeostasis, paving the way for future precision medicine in bone metabolic diseases.\n --- END ACTUAL ABSTRACT FOR 42458565 ---\n\n- ERROR: You cited ID: 42341587 for the quote: \"Peptides have emerged as versatile tools in breast cancer-targeted therapy, functioning as tumor-targeting ligands, vaccine epitopes, and delivery enhancers across various platforms.\"\n FACT: Strict Misquote Detected!

Conventional treatments, including immunotherapies and targeted inhibitors, face three main challenges: tumor heterogeneity, drug resistance, and systemic toxicity. Nucleic acid therapeutics (NATs) encompass a diverse array of DNA- and RNA-based tools, including small interfering RNA (siRNA), microRNA (miRNA), messenger RNA (mRNA), antisense oligonucleotides (ASOs), and clustered regularly interspaced short palindromic repeats (CRISPR)-associated (Cas) systems. These tools are central to developing precision oncology approaches that operate through direct gene regulation, mutation correction, and immune system reprogramming. The clinical application of NATs currently faces three main obstacles, which include their vulnerability to enzymatic degradation, their limited ability to penetrate tissues, and their tendency to cause off-target effects. The field has progressed through the implementation of nanoformulation techniques, which utilize lipid-based polymeric and metallic carriers together with exosomes and DNA origami, and hybrid nanostructures as new platforms to enhance the stability of drugs and their cellular absorption and targeted delivery to tumors. The scientists developed functionalized nanocarriers by combining targeting ligands with materials that could respond to specific environmental changes, which allowed them to manage drug distribution and release patterns throughout the tumor microenvironment. This review focuses on establishing a direct connection between nucleic acid design and nanotechnology through an analysis of mechanistic details and progress in preclinical and clinical research, and the difficulties encountered during the progress to practical applications. The research demonstrates how artificial intelligence and bioinspired nanocarriers and multi-omics data integration create new opportunities for developing personalized adaptive nanogenetic treatment methods, which will treat lung cancer.

However, there is a lack of systematic bibliometric analysis. Therefore, this study employed bibliometric methods to comprehensively review the research trends and hotspots in this field. A comprehensive search was conducted using the Web of Science Core Collection (WoSCC) and Scopus databases for English-language literature published between January 1, 2010, and August 1, 2025. A multidimensional visual analysis of nations, institutions, authors, journals, references, and keywords was performed on the 508 included articles utilizing bibliometric tools VOSviewer, CiteSpace, and Bibliometrix. The number of publications in this field shows an upward trend. From 2010 to 2016, it was in the initial growth stage; from 2017 to 2021, it entered a period of steady growth. After 2022, research activities increased significantly and reached a peak in 2025 (n=131). Frontiers in Immunology (n=25) had the highest number of publications, while Nature Nanotechnology (1,299) had the highest co-citation frequency. Wang Yi-Ching (n=5, H-index =4) and Yang Bo (n=4, H-index =4) are the core authors representing the development of this discipline. China (n=370) has the largest number of publications, and representative institutions include Fudan University (n=19), Chinese Academy of Medical Sciences (n=15), and Shanghai Jiao Tong University (n=14).

Research hotspots have gradually shifted from the correlation between the early macrophage polarization phenotype and the pathological characteristics of lung cancer to molecular mechanisms such as signaling pathways, metabolic reprogramming, and exosomes, and have further expanded to the directions of nanoparticle targeted delivery and clinical translation of immune checkpoint inhibitors. The research in this field has advanced from phenotypic description to mechanism integration and translational research, with nano-intervention and immune regulation being the cutting-edge directions.

As principal mediators of intercellular communication within the tumor microenvironment, secretory autophagosomes (SAPs) propel breast cancer progression and metastasis by modulating the establishment of the pre-metastatic niche, thereby positioning them as highly promising biomarkers for breast cancer. However, the paucity of accurate and simplified quantitative tools has impeded the direct detection of circulating SAPs. This study presents a sensing platform that couples nanozyme cascade catalysis with a covalent organic frameworks (COFs)-derived nanohydrogel (CGNH) for precisely assessing trace-level SAPs. The AuNBP@PtPd-MoS2 nanozyme, via its stereoconfiguration and trimetallic synergy, recapitulates the dual enzyme-mimicking activities of GOx/CAT. Hence, it enables self-sustained interfacial charge transfer. As a signal probe, it efficiently accelerates self-cascade catalysis and electrochemical mass transfer. Additionally, CGNH creates an ideal interface for SAPs enrichment and cascade catalysis, featuring a hierarchical pore structure, a hybrid conductive network, and suitable biocompatibility. With self-assembled antifouling peptide nanoparticles (APNP) as a shielding barrier, the platform reliably detects SAPs in intricate biological matrices verified using cellular, murine and clinical specimens. Compared with conventional biomarkers, SAPs produce more informative readouts on disease progression. This electrochemical platform differentiates between benign and malignant breast diseases and healthy controls with high diagnostic accuracy (AUC\u202f=\u202f0.962), especially for gray-zone differentiation and metastasis forecasting. This study offers new avenues for SAPs-based liquid biopsy to identify signs of breast cancer metastasis and is expected to become a reliable non-invasive tool for personalized breast cancer management.\n --- END ACTUAL ABSTRACT FOR 42580228 ---\n\n- ERROR: You cited ID: 42543528 for the quote: \"This study investigated the encapsulation and controlled release of human spinal cord organoid (hSCO)-derived EVs in viscoelastic hyaluronic acid (HA) hydrogels.\"\n FACT: Strict Misquote Detected!

The secreted extracellular vesicles (EVs) of organoids, in particular the small-sized EV subset referred as exosomes (30-200 nm), have emerged as novel therapeutics in regenerative medicine. This study investigated the encapsulation and controlled release of human spinal cord organoid (hSCO)-derived EVs in viscoelastic hyaluronic acid (HA) hydrogels and assessed their impact on organoid patterning. A series of pH-responsive hydrogels were fabricated, leading to sustained EV release regulated by viscoelastic properties. The pH of these hydrogels decreased from 9 to 7 during incubation, which altered hydrogel viscoelasticity, thereby modulating EV release kinetics. In addition, EV-loaded hydrogels regulated key hSCO patterning markers such as DBX1 and ISL1.

To deliver drugs specifically to cancer cells that overexpress CD44, this study developed hyaluronic acid (HA)-functionalized dextran (DEX) polymeric nanoparticles (ETP-DEX-HA-NPs). Optimised nanoparticles (174.7\u2009\u00b1\u20093.2\u2009nm, -12.83\u2009\u00b1\u20091.1\u2009mV) demonstrated significant entrapment efficiency (62.75\u2009\u00b1\u20092.32%) and drug loading (55.64\u2009\u00b1\u20093.86%), with partial amorphization validated by FTIR, XRD, Raman, NMR and DSC analyses. The formulation exhibited prolonged, pH-responsive release, markedly improved solubility (p\u2009<\u20090.05), and greater cytotoxicity in HCT-116 cells (IC50: 6.83\u2009\u00b1\u20090.35\u2009\u00b5g/mL compared to 41.89\u2009\u00b1\u20091.02\u2009\u00b5g/mL for free ETP). It facilitated CD44-mediated uptake, enhanced apoptosis, induced G2/M arrest, elevated ROS production and inhibited migration while preserving biocompatibility. Network pharmacology and molecular docking identified key interactions with CRC-related targets (e.g. TOP2A, BCL2).

This review aims to present an integrated model of lymphatic and hematogenous dissemination that provides a unified framework for understanding metastatic progression. Methods: The published literature on lymphatic biology, microvascular physiology, tumor immunology, and cancer metastasis was critically reviewed and integrated to develop a comprehensive anatomical and physiological model of cancer dissemination. Results: The proposed model identifies lymphatic dissemination as the predominant metastatic route in many solid tumors. Cancer cells enter structurally permissive initial lymphatic capillaries and are transported to the sentinel lymph node (SLN), where interactions with the tumor microenvironment may eliminate disseminated cells, maintain dormancy, or facilitate immune escape and further dissemination. Cancer cells that survive within or escape beyond the SLN subsequently travel through collecting lymphatics and the thoracic or right lymphatic duct to enter the systemic venous circulation. Following cardiopulmonary transit, surviving cells may be redistributed through the systemic arterial circulation to distant organs. A secondary pathway involves direct hematogenous intravasation through post-capillary venules, where reduced shear stress, increased endothelial permeability, and permissive endothelial biology facilitate entry into the venous circulation. Thus, lymphatic and direct venular pathways ultimately converge in the venous circulation before systemic arterial dissemination. Conclusions: This unified model integrates lymphatic and hematogenous dissemination into a coherent anatomical and physiological framework. By emphasizing the SLN as an early immunologic checkpoint and the arterial circulation as the final distribution network for disseminated cancer cells, this review provides a conceptual basis for understanding metastatic patterns and identifying biomarkers and therapeutic vulnerabilities.\n --- END ACTUAL ABSTRACT FOR 42512321 ---\n\n- ERROR: You cited ID: 42353096 for the quote: \"p51-modified exosomes exhibited superior HER2 specific uptake.

Approximately 10-20% of gastric cancers overexpress HER2, conferring aggressive tumor characteristics and poor survival, yet resistance to trastuzumab-based targeted therapy and limited intratumoral antibody penetration continue to restrict clinical outcomes. This study evaluated HER2-targeted exosomes as a delivery platform. Exosomes were engineered to express the p51 peptide, a high-affinity HER2-binding ligand, and loaded with 17-dimethylaminoethylamino-17-demethoxygeldanamycin (17-DMAG), a potent HSP90 inhibitor. The cellular uptake and antitumor efficacy of p51-Exo17-DMAG were assessed in vitro using NCI-N87 and AGS cells and in vivo using a mouse xenograft model. p51-modified exosomes exhibited superior HER2 specific uptake. Treatment with p51-Exo17-DMAG significantly increased apoptosis, as demonstrated by elevated PARP and caspase3 cleavage, and downregulated oncogenic signaling molecules, including p-AKT, CDK2, VEGF, and c-Myc. Furthermore, p51-Exo17-DMAG increased the number of TUNEL-positive cells. In the NCI-N87 xenograft model, systemic administration of p51-Exo17-DMAG significantly inhibited tumor growth without toxicity or histological damage to major organs. Tumor analysis confirmed increased apoptosis and reduced proliferation in vivo. These findings demonstrate that p51-engineered exosomes provide an efficient, selective, and safe platform for HER2-targeted delivery of 17-DMAG, offering a promising precision medicine strategy for HER2-positive gastric cancer.\n --- END ACTUAL ABSTRACT FOR 42353096 ---\n\n- ERROR: You cited ID: 42341362 for the quote: \"This approach is realized through a rationally designed platform, Szd + AP@ExoE-Ldlr, which integrates APOA1-functionalized exosomes for hepatocyte-targeted delivery with a preemptive macrophage blockade using the clinical ultrasound contrast agent Sonazoid.\"\n FACT: Strict Misquote Detected!

This recalcitrance stems largely from loss-of-function mutations within the low-density lipoprotein receptor (LDLR) gene, which severely undermine the efficacy of standard therapeutic regimens. Here, we report a bioinspired \"targeting and blockade\" strategy for the efficient delivery of functional Ldlr mRNA to hepatocytes. This approach is realized through a rationally designed platform, Szd + AP@ExoE-Ldlr, which integrates APOA1-functionalized exosomes for hepatocyte-targeted delivery with a preemptive macrophage blockade using the clinical ultrasound contrast agent Sonazoid (Szd). The APOA1 modification confers specific recognition by the scavenger receptor class B type 1 on hepatocytes, while the pre-saturation of Kupffer cells with Szd significantly mitigates nonspecific clearance by the mononuclear phagocyte system (MPS). In a HoFH murine model, this synergistic strategy markedly enhanced the accumulation of exosomes in hepatocytes and achieved robust restoration of hepatic LDLR expression. Consequently, it elicited a profound correction of the atherogenic lipid profile and substantially attenuated the progression of atherosclerosis. A comprehensive biosafety evaluation confirmed the excellent biocompatibility of this platform. Our work provides a promising and broadly applicable solution for the treatment of liver-related genetic disorders by simultaneously overcoming the critical barriers of targeted delivery and MPS evasion.\n --- END ACTUAL ABSTRACT FOR 42341362 ---\n\n\n\u2705 PASSED (DO NOT CHANGE THESE):\n- \"Rational engineering strategies, including surface modification, self-loading hybridization, genetic manipulation, and pH-responsive coating, can optimize the therapeutic performance of BEVs.\" (Source: 42561425)\n- \"The liposomes maintain a negative surface charge under physiological conditions to prolong circulation, but undergo pH-responsive conversion to a positive charge within the acidic tumor microenvironment (pH 6.5-6.8), thereby improving tumor-selective internalization.\" (Source: 42540442)\n- \"The exosome component provides inherent biological targeting to HCC cells.

Probiotics and postbiotics represent promising preclinical candidates to alleviate these unmet clinical bottlenecks. Bacterial extracellular vesicles (BEVs) are naturally secreted bacterial nanovesicles carrying abundant bioactive cargos, whose bioactivity and safety are highly strain-dependent. Probiotics-derived BEVs can remodel gut homeostasis, repair epithelial barriers, and regulate mucosal immunity to suppress the inflammatory vicious cycle in IBD, while pathogen-/pathobiont-derived BEVs loaded with lipopolysaccharide and virulence factors exacerbate intestinal inflammation. Native BEVs are restricted by low cargo loading, poor gastrointestinal stability and inadequate colon tropism. Rational engineering strategies, including surface modification, self-loading hybridization, genetic manipulation, and pH-responsive coating, can optimize the therapeutic performance of BEVs. This review systematically summarizes BEVs biological mechanisms, engineering approaches, and translational obstacles and outlines prospects for the design of intelligent multifunctional BEVs and standardized large-scale manufacturing as future directions, providing theoretical support for oral BEVs nanotherapies against IBD.\n --- END ACTUAL ABSTRACT FOR 42561425 ---\n\n\n\u2705 PASSED (DO NOT CHANGE THESE):\n- \"Rational engineering strategies, including surface modification, self-loading hybridization, genetic manipulation, and pH-responsive coating, can optimize the therapeutic performance of BEVs.\" (Source: 42561425)\n- \"The liposomes maintain a negative surface charge under physiological conditions to prolong circulation, but undergo pH-responsive conversion to a positive charge within the acidic tumor microenvironment (pH 6.5-6.8), thereby improving tumor-selective internalization.\" (Source: 42540442)\n- \"The exosome component provides inherent biological targeting to HCC cells.

"rawResponse": "Even though this fact check looked at unique up-to-date abstracts, new evidence may refute this answer in the future. 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]\n\"The conjugation of plant-derived nanovesicles with pH-responsive or enzyme-cleavable 'hitchhiker' peptides enables triggered release within the lymphatic pre-metastatic niche, thereby enhancing the therapeutic payload concentration specifically at sites of active lymphangiogenesis in patients with early-stage lymphatic metastasis.\"\n\nThis claim is Plausible (5/7) based on the evidence, though direct verification of \"plant-derived nanovesicles\" specifically modified with \"hitchhiker\" peptides for \"lymphatic pre-metastatic niche\" targeting is currently an extrapolation of parallel technologies. The provided literature confirms that (1) plant-derived nanovesicles have therapeutic potential in inflammatory and cancer models, (2) pH-responsive and enzyme-cleavable linkers are effective for site-specific delivery in these models, and (3) targeting biomarkers of lymphatic metastasis (such as CCR2 or VEGF-C pathways) can enhance delivery to the metastatic niche. However, a single study synthesizing all these specific components (plant-EVs + hitchhiker peptide + lymphatic targeting) is not explicitly detailed in the provided set.\n\n### [ABSTRACT & REWRITTEN CLAIM]\nPlant-derived extracellular vesicles (EVs) are emerging as versatile, biocompatible platforms for targeted cancer therapy. While current literature establishes the efficacy of engineering plant-EVs with pH-responsive shells or targeting ligands to modulate tumor environments, the specific coupling of \"hitchhiker\" peptide-mediated lymph node (LN) targeting with pH-triggered payload release in a pre-metastatic niche remains a theoretical design paradigm supported by the synergistic capabilities of these distinct technologies.\n\n### [INTRODUCTION & JUSTIFICATION]\nThe therapeutic application of extracellular vesicles (EVs) has expanded from mere drug vehicles to intelligent, responsive nanoplatforms. By exploiting the acidic microenvironment inherent to tumor progression and sites of inflammation, researchers have developed pH-responsive coatings that ensure cargo protection during circulation and selective release upon accumulation. In the context of early lymphatic metastasis, the pre-metastatic niche provides a distinct physiological landscape. Strategies involving nanoparticle hitchhiking\u2014such as the MCP1-derived peptides\u2014have demonstrated the ability to exploit monocyte-mediated lymphatic transport to achieve significant accumulation in metastatic nodes. By integrating these \"hitchhiker\" mechanisms with the structural stability and cargo-loading capabilities of plant-derived vesicles, it is mechanistically plausible that therapeutic efficacy in nodal disease could be substantially improved. The literature supports that \"Rational engineering strategies, including surface modification, self-loading hybridization, genetic manipulation, and pH-responsive coating, can optimize the therapeutic performance of BEVs.\" Furthermore, the use of targeted agents, such as CCR2-binding peptides, provides a clear roadmap for achieving \"monocyte hitchhiking,\" which is crucial as \"LN targeting was dependent on monocyte hitchhiking, as monocyte depletion decreased accumulation by >70%.\"\n\n### [DISCUSSION: NOVEL & OVERLOOKED]\n* Plant-derived nanovesicles exhibit significant cross-kingdom therapeutic potential due to their conservation of metabolic and immune-related pathways.\n* The use of \"hitchhiking\" onto endogenous circulating cells, such as monocytes, allows for significantly increased transport across the lymphatic endothelium.\n* pH-responsive hydrogel shells enable the protection of sensitive cargos (like siRNAs or enzymes) from premature degradation in the systemic circulation.\n* Targeting the CCR2 pathway allows for the specific recognition of metastatic lymph nodes, where this biomarker is highly expressed.\n* Integration of plant-EVs with inorganic materials (e.g., SPIONs or ZIF-8) offers dual-modal therapy, enabling both spatial guidance and triggered drug release.\n* Pre-metastatic niche formation involves active remodeling of the lymphovascular architecture, providing a window of opportunity for targeted intervention before overt tumor colonization.\n* Microfluidic technology facilitates the fabrication of uniform-sized nanocarriers that improve standardized, large-scale manufacturing potential.\n\n### [EVIDENCE, METHODOLOGY & CITATIONS]\n1.

Existing technologies available for NO therapy, however, provide poor bioactivity within lymphatic tissues. In this work, we address this technology gap with a NO encapsulation and delivery strategy leveraging the formation of S-nitrosothiols on lymphatic-targeting pluronic-stabilized, poly(propylene sulfide)-core nanoparticles (SNO-NP). We evaluated in vivo the lymphatic versus systemic delivery of NO resulting from intradermal administration of SNO-NP benchmarked against a commonly used, commercially available small molecule S-nitrosothiol NO donor, examined signs of toxicity systemically as well as localized to the site of injection, and investigated SNO effects on lymphatic transport and NP uptake by lymph node (LN)-resident cells. Donation of NO from SNO-NP, which scaled in proportion to the total administered dose, enhanced LN accumulation by two orders of magnitude without substantially reducing lymphatic transport of NP or the viability and extent of NP uptake by LN-resident cells. Additionally, NO delivery by SNO-NP was accompanied by low-to-negligible NO accumulation in systemic tissues with no apparent inflammation. These results suggest the utility and selectivity of SNO-NP for the targeted treatment of NO-regulated diseases that afflict lymphatic tissues. \u00a9 2018 Wiley Periodicals, Inc.

To reduce the amount of contrast agents injected in patients while fully benefitting both modalities, dual-modality probes are required. This study was first aimed at developing a hybrid PET-MRI probe by labeling superparamagnetic iron oxide nanoparticles (SPIONs) with 64Cu using a fast and chelator-free conjugation method, and second, to demonstrate the ability of the agent to target sentinel lymph nodes (SLNs) in vivo using simultaneous PET-MRI imaging. High labeling efficiency of 97% produced within 10-15\u2009min was demonstrated at room temperature. 64Cu-SPIONs were chemically stable in mouse serum for 24\u2009h and after intradermal injection in the hind paw of C57BL/6J mice, demonstrated specific accumulation in the SLN. Simultaneous PET-MRI clearly demonstrated visualization of 64Cu-SPIONs, in dynamic and static imaging sequences up to 24\u2009h after administration. The use of a single hybrid probe and simultaneous hybrid imaging provides an efficient, complementary integration of quantitation and is expected to improve preoperative planning and intraoperative guidance of cancer treatments.",

The disease has a worldwide distribution, with endemic areas in Brazil, and is caused by a complex of species, including Sporothrix brasiliensis. Some fungi release extracellular vesicles (EVs) that can interact with the host cell and modulate the host immune response. The aim of this study was to analyze the participation of S. brasiliensis EVs in the modulation of dendritic cells (DCs) and in the control of infection in vivo. Our results showed that in vitro, the EVs isolated from S. brasiliensis induced an increase in the phagocytic index and fungal burden in DCs. In addition, we observed a significant increase in IL-12p40 and TNF-\u03b1 cytokine production. Then, the EVs were inoculated into BALB/c mice before subcutaneous infection with yeast, and the lesion was analyzed after 21, 35, and 42 days. An increase in fungal burden and lesion diameter were observed after 21 days in mice inoculated with a high concentration of EVs. However, after 35 days, we observed a regression of the lesion, which persisted until 42 days after infection. Interestingly, we observed an increase in fungal burden in these mice. In addition, we observed the presence of immunogenic components and proteins that could be related with virulence in EVs. These results suggest that EVs can play an important role in virulence and modulation of the host immune system during experimental S. brasiliensis infection.",
"30889749": "ID: 30889749\nTitle: Surface charge of well-defined polymeric nano-stars regulates non-invasive fluorescence imaging of lymph node.\nAbstract: Accurate identification of sentinel lymph node (SLN) is crucial for clinical SLN biopsy surgery. Herein, we developed an innovative nanoprobe based on well-defined core crosslinked star (CCS) polymers for non-invasive fluorescence imaging of SLN. A well-defined biodegradable CCS polymer comprising multiple polyethylene glycol (PEG) arms and carboxyl terminal groups (denoted as CCS-COOH) was synthesized successfully by reversible addition-fragmentation chain transfer polymerization with a disulfide-based crosslinker reagent. Besides, CCS-COOH was coupled by tert-butyl carbazate to produce the CCS derivative with neutral butoxycarbonyl (Boc) terminal groups (denoted as CCS-Boc). By the removal of Boc groups, another CCS derivative with positive primary amino terminal groups (denoted as CCS-NH2) was also yielded. These CCS polymers had similar particle size but different surface charge. For SLN fluorescence imaging, the CCS polymers labeled by CY7, a near-infrared probe, exhibited superior in vitro photo-stability to CY7 alone. After intradermal injection of the CY7-labeled CCS polymers in a mouse model, they could efficiently accumulate in the lymph node of the mouse. CY7-labeled CCS-COOH having negatively-charged surface displayed longer duration time and higher fluorescence intensity in the lymph node as compared to its counterparts with neutral or positive charge surface. In vitro and in vivo toxicity tests supported low cytotoxicity of these CCS polymers against cell lines and low systemic toxicity. The results of this work highlight the potential of negatively-charged near-infrared-emitting CCS polymer as a new nanoprobe for safe and efficient SLN imaging.",
"31141293": "ID: 31141293\nTitle: Mannose-Modified Serum Exosomes for the Elevated Uptake to Murine Dendritic Cells and Lymphatic Accumulation.\nAbstract: The surface of bovine serum-derived exosomes (EXOs) are modified with \u03b1-d-mannose for facile interaction with mannose receptors on dendritic cells (DCs) and for efficient delivery of immune stimulators to the DCs. The surface of the EXOs is modified with polyethylene glycol (PEG) without particle aggregation (\u224850 nm) via the incorporation of 1,2-distearoyl-sn-glycero-3-phosphoethanolamine (DSPE) into the lipid layer of the EXO, compared to chemical conjugation by N-hydroxysuccinimide activated PEG (NHS-PEG). PEG modification onto the exosomal surface significantly decreases the non-specific cellular uptake of the EXOs into the DCs. However, the EXOs with mannose-conjugated PEG-DSPE (EXO-PEG-man) exhibit excellent intracellular uptake into the DCs and boost the immune response by the incorporation of adjuvant, monophosphoryl lipid A (MPLA) within the EXO. After an intradermal injection, a higher retention of EXO-PEG-man is observed in the lymph nodes, which could be used for the efficient delivery of immune stimulators and antigens to the lymph nodes in vivo.",
"31871957": "ID: 31871957\nTitle: Nanoparticles versus Dendritic Cells as Vehicles to Deliver mRNA Encoding Multiple Epitopes for Immunotherapy.\nAbstract: The efficacy of antigen-specific immunotherapy relies heavily on efficient antigen delivery to antigen-presenting cells and engagement of as many disease-relevant T\u00a0cells as possible in various lymphoid tissues, which are challenging to achieve. Here, we compared two approaches to deliver mRNA encoding multiple epitopes targeting both CD4+ and CD8+ T\u00a0cells: a lipid-based nanoparticle platform to target endogenous antigen-presenting cells in\u00a0vivo versus ex\u00a0vivo mRNA-electroporated dendritic cells. After intraperitoneal injection, the nanoparticle platform facilitated efficient entry of mRNA into various endogenous antigen-presenting cells, including lymph node stromal cells, and elicited robust T\u00a0cell responses within a wider network of lymphoid tissues compared with dendritic cells. Following intravenous injection, mRNA-electroporated dendritic cells and the nanoparticle platform localized primarily in lung and spleen, respectively. When administered locally via an intradermal route, both platforms resulted in mRNA expression at the injection site and in robust T\u00a0cell responses in draining lymph nodes. This study indicates that multiple epitopes, customizable for specific patient populations and encoded by mRNA, can be targeted to different lymphoid tissues based on delivery vehicle and route, and constitute the groundwork for future studies using mRNA to reprogram exogenous or endogenous APCs for immunotherapy.",
"31917298": "ID: 31917298\nTitle: Carboxyl-, sulfonyl-, and phosphate-terminal dendrimers as a nanoplatform with lymph node targeting.\nAbstract: The development of drug delivery vehicles to cancer and/or immune cells in lymph nodes is important for cancer diagnosis, therapy, and immunotherapy. We previously reported that anionic carboxyl-terminal dendrimers were accumulated in lymph nodes. In this study, three anionic dendrimers with carboxyl-, sulfonyl-, and phosphate-terminal groups were prepared to examine the lymph node targeting and the association with immune cells in the lymph nodes. These anionic dendrimers were accumulated in the lymph node by intradermal injection. Although the carboxyl- and sulfonyl-terminal dendrimers were diffused from the injection site, the phosphate-terminal dendrimers were mostly retained. The phosphate-terminal dendrimer was recognized by the macrophages, dendritic cells, and B cells in the lymph node, whereas the carboxyl- and sulfonyl-terminal dendrimers were not. Our results show that these anionic dendrimers were accumulated in the lymph node where the association with immune cells could be controlled by the terminal structure of the dendrimer. The phosphate-terminal dendrimer can be used as a nanoplatform for the delivery of some bioactive molecules to some immune cells, including B cells, in the lymph node.",
"32032584": "ID: 32032584\nTitle: Gliadin Nanoparticles Induce Immune Tolerance to Gliadin in Mouse Models of Celiac Disease.\nAbstract: Celiac disease could be treated, and potentially cured, by restoring T-cell tolerance to gliadin. We investigated the safety and efficacy of negatively charged 500-nm poly(lactide-co-glycolide) nanoparticles encapsulating gliadin protein (TIMP-GLIA) in 3 mouse models of celiac disease. Uptake of these nanoparticles by antigen-presenting cells was shown to induce immune tolerance in other animal models of autoimmune disease. We performed studies with C57BL/6; RAG1-/- (C57BL/6); and HLA-DQ8, huCD4 transgenic Ab0 NOD mice. Mice were given 1 or 2 tail-vein injections of TIMP-GLIA or control nanoparticles. Some mice were given intradermal injections of gliadin in complete Freund's adjuvant (immunization) or of soluble gliadin or ovalbumin (ear challenge). RAG-/- mice were given intraperitoneal injections of CD4+CD62L-CD44hi T cells from gliadin-immunized C57BL/6 mice and were fed with an AIN-76A-based diet containing wheat gluten (oral challenge) or without gluten. Spleen or lymph node cells were analyzed in proliferation and cytokine secretion assays or by flow cytometry, RNA sequencing, or real-time quantitative polymerase chain reaction. Serum samples were analyzed by gliadin antibody enzyme-linked immunosorbent assay, and intestinal tissues were analyzed by histology. Human peripheral blood mononuclear cells, or immature dendritic cells derived from human peripheral blood mononuclear cells, were cultured in medium containing TIMP-GLIA, anti-CD3 antibody, or lipopolysaccharide (controls) and analyzed in proliferation and cytokine secretion assays or by flow cytometry. Whole blood or plasma from healthy volunteers was incubated with TIMP-GLIA, and hemolysis, platelet activation and aggregation, and complement activation or coagulation were analyzed. TIMP-GLIA did not increase markers of maturation on cultured human dendritic cells or induce activation of T cells from patients with active or treated celiac disease. In the delayed-type hypersensitivity (model 1), the HLA-DQ8 transgenic (model 2), and the gliadin memory T-cell enteropathy (model 3) models of celiac disease, intravenous injections of TIMP-GLIA significantly decreased gliadin-specific T-cell proliferation (in models 1 and 2), inflammatory cytokine secretion (in models 1, 2, and 3), circulating gliadin-specific IgG/IgG2c (in models 1 and 2), ear swelling (in model 1), gluten-dependent enteropathy (in model 3), and body weight loss (in model 3). In model 1, the effects were shown to be dose dependent. Splenocytes from HLA-DQ8 transgenic mice given TIMP-GLIA nanoparticles, but not control nanoparticles, had increased levels of FOXP3 and gene expression signatures associated with tolerance induction. In mice with gliadin sensitivity, injection of TIMP-GLIA nanoparticles induced unresponsiveness to gliadin and reduced markers of inflammation and enteropathy. This strategy might be developed for the treatment of celiac disease.",
"33080460": "ID: 33080460\nTitle: Lymph-directed nitric oxide increases immune cell access to lymph-borne nanoscale solutes.\nAbstract: Lymph nodes (LNs) are immune organs housing high concentrations of lymphocytes, making them critical targets for therapeutic immunomodulation in a wide variety of diseases. While there is great interest in targeted drug delivery to LNs, many nanoscale drug delivery carriers have limited access to parenchymal resident immune cells compared to small molecules, limiting their efficacy. Nitric oxide (NO) is a potent regulator of vascular and lymphatic transport and a promising candidate for modulating nanocarrier access to LNs, but its lymphatic accumulation is limited by its low molecular weight and high reactivity. In this work, we employ S-nitrosated nanoparticles (SNO-NP), a lymphatic-targeted delivery system for controlled NO release, to investigate the effect of NO application on molecule accumulation and distribution within the LN. We evaluated the LN accumulation, spatial distribution, and cellular distribution of a panel of fluorescent tracers after intradermal administration alongside SNO-NP or a small molecule NO donor. While SNO-NP did not alter total tracer accumulation in draining lymph nodes (dLNs) or affect active cellular transport of large molecules from the injection site, its application enhanced the penetration of nanoscale 30\u00a0nm dextrans into the LN and their subsequent uptake by LN-resident lymphocytes, while nontargeted NO delivery did not. These results further extended to a peptide-conjugated NP drug delivery system, which showed enhanced uptake by B cells and dendritic cells when administered alongside SNO-NP. Together, these results highlight the utility of LN-targeted NO application for the enhancement of nanocarrier access to therapeutically relevant LN-resident immune cells, making NO a potentially useful tool for improving LN drug delivery and immune responses.",
"33380496": "ID: 33380496\nTitle: Effective and Safe Stimulation of Humoral and Cell-Mediated Immunity by Intradermal Immunization with a Cyclic Dinucleotide/Nanoparticle Combination Adjuvant.\nAbstract: Intradermal (ID) immunization is an attractive route of vaccination because it targets tissue rich in dendritic cells, has dose-sparing potential, and allows needle-free delivery. However, few adjuvants are effective, nonreactogenic, and compatible with needle-free delivery devices. In this study, we demonstrate that a combination adjuvant composed of cyclic-di-AMP (cdAMP) and the plant-derived nanoparticle adjuvant Nano-11 significantly enhanced the immune response to ID-injected vaccines in mice and pigs with minimal local reaction at the injection site. The cdAMP/Nano-11 combination adjuvant increased Ag uptake by lymph node-resident and migratory skin dendritic cell subpopulations, including Langerhans cells. ID immunization with cdAMP/Nano-11 expanded the population of germinal center B cells and follicular helper T cells in the draining lymph node and Ag-specific Th1 and Th17 cells in the spleen. It elicited an enhanced immune response with a significant increase of IgG1 and IgG2a responses in mice at a reduced dose compared with i.m. immunization. An increased IgG response was observed following needle-free ID immunization of pigs. Nano-11 and cdAMP demonstrated a strong synergistic interaction, as shown in the activation of mouse, human, and porcine APC, with increased expression of costimulatory molecules and secretion of TNF and IL-1\u03b2. The combination adjuvant induced robust activation of both NF-\u03baB and IFN regulatory factor signaling pathways and the NLRP3 inflammasome. We conclude that the combination of Nano-11 and cdAMP is a promising adjuvant for ID delivery of vaccines that supports a balanced immune response.",
"33712074": "ID: 33712074\nTitle: The value of contrast-enhanced ultrasound in determining the location of sentinel lymph nodes in breast cancer.\nAbstract: This study aimed to explore the sentinel lymph node (SLN) identification rate in breast cancer by subcutaneous and intradermal injection of ultrasound contrast agent in the mammary areola region, compared to the results achieved with methylene blue (MB). A total of 390 breast cancer patients with planned sentinel lymph node biopsy from our breast surgery department from July 2017 to February 2019 were enrolled. All patients were subjected to preoperative contrast-enhanced ultrasound (CEUS), that involved an intracutaneous injection of 1 mL ultrasonic contrast agent (UCA) at 3 and 6 o 'clock, as well as a subcutaneous injection of 1 mL UCA at 9 and 12 o'clock. The enhanced lymph nodes along the enhanced lymphatic vessels from the mammary areola were traced. The number of enhanced lymph nodes were recorded, and an ultrasound-guided injection of 1:10 diluted carbon nanoparticles were used to mark all first site enhanced lymph nodes (i.e., SLNs). An intraoperative dye method (MB) was used to track the SLNs and the results were compared with the CEUS findings. Among the 390 cases of breast cancer, enhanced SLNs were observed in 373 patients after an injection of UCA with an identification rate of 95.64\u2009% (373/390), compared to the identification rate of 92.05\u2009% (359/390) using the intraoperative MB. The difference between the two methods was statistically significant (P\u2009=\u20090.016). And among the 390 patients, a total of 808 enhanced lymph nodes were traced by preoperative CEUS, with a median of 2 (1,3). A total of 971 blue-stained lymph nodes were traced using the intraoperative MB, with a median of 2 (2,3), indicating a statistically significant difference (p\u2009<\u20090.001). Intradermal and subcutaneous injections of UCA in the mammary areola region may have clinical application value for the identification and localization of SLNs in breast cancer patients. The identification rate is higher than that of blue dye method, which can be used as a new tracer of sentinel lymph node biopsy and complement other staining methods to improve the success rate.",
"35381399": "ID: 35381399\nTitle: Nanoparticles with dense poly(ethylene glycol) coatings with near neutral charge are maximally transported across lymphatics and to the lymph nodes.\nAbstract: Lymphatic vessels have recently been shown to effectively deliver immune modulatory therapies to the lymph nodes, which enhances their therapeutic efficacy. Prior work has shown that lymphatics transport 10-250 nm nanoparticles from peripheral tissues to the lymph node. However, the surface chemistry required to maximize this transport is poorly understood. Here, we determined the effect of surface poly(ethylene glycol) (PEG) density and size on nanoparticle transport across lymphatic endothelial cells (LECs) by differentially PEGylated model polystyrene nanoparticles. Using an established in-vitro lymphatic transport model, we found PEGylation improved the transport of 100 and 40 nm nanoparticles across LECs 50-fold compared to the unmodified nanoparticles and that transport is maximized when the PEG is in a dense brush conformation or high grafting density (Rf/D\u00a0=\u00a04.9). We also determined that these trends are not size-dependent. PEGylating 40 nm nanoparticles improved transport efficiency across LECs 68-fold compared to unmodified nanoparticles. We also found that PEGylated 100 nm and 40 nm nanoparticles accumulate in lymph nodes within 4 h after intradermal injection, while unmodified nanoparticles accumulated minimally. Densely PEGylated nanoparticles traveled the furthest distance from the injection site and densely PEGylated 40 nm nanoparticles had maximum accumulation in the lymph nodes compared to low density PEGylated and unmodified nanoparticles. Finally, we determined that nanoparticles are transported via both paracellular and transcellular mechanisms, and that PEG conformation modulates the cellular transport mechanisms. Our results suggest that PEG conformation is crucial to maximize nanoparticle transport across LECs and into lymphatic vessels, making PEG density a crucial design. Optimizing PEG density on nanoparticle formulations has the potential to enhance immunotherapeutic and vaccine outcomes. STATEMENT OF SIGNIFICANCE: Lymphatic vessels are an emerging target for drug delivery both in the context of modulating immune responses and enhancing bioavailability by avoiding first pass hepatic metabolism after oral delivery. Lymphatic vessels are the natural conduits from peripheral tissues to the lymph nodes, where the adaptive immune response is shaped, and eventually to systemic circulation via the thoracic duct. Lymphatics can be targeted via nanoparticles, but the surface chemistry required to maximize nanoparticle transport by lymphatics vessels remains poorly understood. Here, we demonstrate that coating nanoparticles with hydrophilic polyethylene glycol (PEG) effectively enhances their transport across lymphatic endothelial cells in vitro and in vivo and that both paracellular and micropinocytosis mechanisms underly this transport. We found that dense PEG coatings maximize lymphatic transport of nanoparticles, thus providing new material design criteria for lymphatic targeted drug delivery.",

This strategy is demonstrated using chondroitin sulfate-coated nanoparticles (OPGMN) grafted with glycocholic acid and mannose for cationic liposomes encapsulated with ovalbumin as an antigen and polyinosine-polycytidylic acid as a cancer-specific adjuvant. OPGMN is absorbed in the gastrointestinal tract and delivered to the lymph nodes when orally administered. Oral delivery of OPGMN induces increased dendritic cell maturation compared to the intradermal route in the lymph node and induces T helper type 1 and type 2 responses, such as immunoglobulin G1 and G2c, interferon-gamma, and interleukin-2, in the blood. Repeated oral administration of OPGMN increases the population of CD3+ CD8+ T cells, CD44high CD62Llow memory T cells, and CD11b+ CD27+ natural killer cells in the blood. OPGMN completely prevents melanoma development in the B16F10-bearing C57BL/6 mouse model by reducing the population of CD4+ CD25+ Foxp3+ regulatory T cells in the blood. This strategy is expected to prevent the recurrence of tumors after various cancer treatments.",

However, their rapid clearance after administration could be a limitation in certain therapeutic settings. To solve this, an engineering strategy is employed to decorate albumin onto the surface of the EVs through surface display of albumin binding domains (ABDs). ABDs were either included in the extracellular loops of select EV-enriched tetraspanins (CD63, CD9 and CD81) or directly fused to the extracellular terminal of single transmembrane EV-sorting domains, such as Lamp2B. These engineered EVs exert robust binding capacity to human serum albumins (HSA) in vitro and mouse serum albumins (MSA) after injection in mice. By binding to MSA, circulating time of EVs dramatically increases after different routes of injection in different strains of mice. Moreover, these engineered EVs show considerable lymph node (LN) and solid tumour accumulation, which can be utilized when using EVs for immunomodulation, cancer- and/or immunotherapy. The increased circulation time of EVs may also be important when combined with tissue-specific targeting ligands and could provide significant benefit for their therapeutic use in a variety of disease indications.",

In a preplanned secondary analysis of a prospective clinical trial (SentiDose) we reported on skin staining after SPIO and blue dye (BD) injections. For SPIO, either a 1.5 mL retroareolar injection on the day of surgery or a 1.0 mL peritumoral/retroareolar injection 1-7 days before surgery was given. A 1.0 mL sub-/intradermal periareolar injection of BD was also administered to all these women. Staining was then assessed at 6, 12 and 24 months after surgery. A total of 270 women received SPIO and were operated on with breast-conserving surgery. Of these, 204 women also received BD. A total of 58 (21.5%) women had an SPIO stain 6 months postoperatively with a median size of 6.8 cm2 (p = 0.56), while 51 (25.0%) had a BD stain with a median size of 8.5 cm2 (p = 0.93). The incidence and size of SPIO and BD staining decreased over time reciprocally. At 24 months, the incidence and median size of SPIO was 23 (8.6%) and 4 cm2, respectively. For BD, the incidence was 14 (6.3%, p = 0.13), and the median size was 3.5 cm2 (p = 0.18). There was, therefore, no statistically significant difference in the incidence or size of skin staining between SPIO and BD over time.",

Therefore, examination of the effects of X-ray irradiation on sentinel lymph nodes and lymphatic vessels, which are involved in antigen presentation, is important for therapy. The hindlimbs of mice were irradiated with X-rays (total radiation doses: 2, 10, and 30\u00a0Gy), and X-ray computed tomography (CT) imaging was performed using 15-nm or 2-nm gold nanoparticles (AuNPs) as contrast agents on days 7, 14, and 28 after irradiation to evaluate the diameter of the collecting lymph vessels and lymph flow within the irradiated area. X-ray CT imaging data using 15-nm AuNPs on day 28 after irradiation showed that the diameter of the collecting lymph vessels was significantly larger in all irradiated groups compared to the control group (p\u00a0\u2264\u00a00.01). CT imaging with 2-nm AuNPs showed that lymphatic drainage was significantly reduced in the lymph nodes irradiated with 10\u00a0Gy and 30\u00a0Gy compared to the lymph nodes irradiated with 2\u00a0Gy (p\u00a0\u2264\u00a00.05). Additionally, immunohistochemical analyses were conducted to evaluate the area density and morphology of high endothelial venules (HEVs) in the lymph nodes, which are important vessels for naive T cells to enter the lymph nodes. The expression level of MECA-79, which specifically localized to HEVs, was significantly decreased in the 10\u00a0Gy and 30\u00a0Gy irradiation groups compared to the control group (p\u00a0\u2264\u00a00.05). There was a significant decrease in normal HEV morphology (p\u00a0\u2264\u00a00.05) and a significant increase in abnormal HEV morphology (p\u00a0\u2264\u00a00.05) in all irradiated groups. These results also showed that X-ray irradiation induced a time- and radiation dose-dependent increase in the diameter of the collecting lymph vessels, stagnation of intralymphatic lymph flow, and a reduction in the area density of HEVs and their abnormal morphology, demonstrating that X-ray irradiation affected the immune responses. Therefore, these findings suggest that X-ray irradiation to lymph nodes may impair the opportunity for antigen presentation in the lymph nodes, which is the key to cancer immunity, and that for this reason, it is important to carefully plan irradiation of sentinel lymph nodes and develop treatment strategies according to future treatment options.",

Superparamagnetic iron oxide nanoparticles (SPIO) have been shown to be equivalent to the dual technique with technetium99m (Tc99) and blue dye (BD) for SLN detection. The aim of this study was to determine the feasibility of detecting SLNs using an ultra-low dose of SPIO. Patients planned for breast conserving surgery and SLN biopsy were included. An intradermal injection of 0.1 mL SPIO was administered at the areolar border up to 7 days before surgery. Tc99/BD was administered according to clinical routine. SLNs were detected during surgery using a handheld magnetometer. All nodes with a magnetic and/or radioactive signal, as well as blue or clinically suspicious nodes, were harvested and analyzed. In 50 patients, SPIO was injected a median of 4 days before surgery. At least one SLN was found in all patients with both methods. A total of 98 SLNs were removed; 90 were detected using SPIO and 88 using Tc99/BD. Of the 90 SLNs detected by SPIO, 80 were Tc99/BD positive (concordance 89%). Histopathological analysis classified 16 patients with tumor cells deposit and 9 with macro-metastasis > 2mm, where one SLN was identified only by the radioactive technique and one only by the magnetic technique. SLN detection using 0.1 mL ultra-low dose SPIO injected intradermally was successful in all patients. A future analysis will determine whether the approach using an ultra-low dose of SPIO injected intradermally will minimize skin staining and MRI artefacts.",
"37517544": "ID: 37517544\nTitle: Logistics and distribution of small extracellular vesicles from the subcutaneous space to the lymphatic system.\nAbstract: Small extracellular vesicles (sEVs) are small, cell-derived particles with sizes of approximately 100\u00a0nm. Since these particles include cargos such as host cell-derived proteins, messenger RNAs, and micro RNAs, they serve as mediators of cell-cell communication. While the analysis of the pharmacokinetic of sEVs after the intravenous injection have been reported, the lymphatic transport of sEVs remains unclear. The objective of this study was to provide insights into the intra-lymphatic trafficking and distribution of sEVs when they are injected into an interstitial space both in normal skin tissue and in cancerous tissue. When sEVs were Subcutaneously administered into the tail base and the tumor tissue, they preferably accumulated in the lymph nodes (LNs), rather than in the liver and the spleen. The findings reported herein show that the lymphatic transport of sEVs was drastically changed in model mice, in which a surgical treatment was used to modify to allow the dominant lymphatic flow from the footpad directly to the axillary LN via the inguinal LN. Based on the results, we conclude that when sEVs are injected into the subcutis space, they are preferably delivered to the LN via the lymphatic system. Further, the extent of accumulation of sEVs in the LN after subcutaneous injection was reduced when they were preliminarily incubated with Proteinase K. These results suggest that the lymphatic drainage of sEVs in normal skin tissue is regulated by membrane proteins on their surface. This reduction, however, was not observed in the case of cancer tissue. This discrepancy can be attributed to the presence of highly permeable lymphatic vessels in the tumor tissue. Further, the major cell subtypes that captured sEVs in the LN were LN-resident medullary sinus macrophages. These collective findings indicate that the lymphatic drainage of sEVs are mediated by proteins and, that they may appear to contribute to the control of the function of immune-responsive cells in the LNs.",

Magnetic resonance imaging (MRI) has been utilized as a noninvasive alternative but is limited by low sensitivity, with only \u223c35% of LN metastases detected, as clinical contrast agents cannot discriminate between healthy and metastatic LNs due to nonspecific accumulation. Nanoparticles targeted to the C-C chemokine receptor 2 (CCR2), a biomarker highly expressed in metastatic LNs, have the potential to guide the delivery of contrast agents, improving the sensitivity of MRI. Additionally, cancer cells in metastatic LNs produce monocyte chemotactic protein 1 (MCP1), which binds to CCR2+ inflammatory monocytes and stimulates their migration. Thus, the molecular targeting of CCR2 may enable nanoparticle hitchhiking onto monocytes, providing an additional mechanism for metastatic LN targeting and early detection. Hence, we developed micelles incorporating gadolinium (Gd) and peptides derived from the CCR2-binding motif of MCP1 (MCP1-Gd) and evaluated the potential of MCP1-Gd to detect LN metastasis. When incubated with migrating monocytes in vitro, MCP1-Gd transport across lymphatic endothelium increased 2-fold relative to nontargeting controls. After administration into mouse models with initial LN metastasis and recurrent LN metastasis, MCP1-Gd detected metastatic LNs by increasing MRI signal by 30-50% relative to healthy LNs. Furthermore, LN targeting was dependent on monocyte hitchhiking, as monocyte depletion decreased accumulation by >70%. Herein, we present a nanoparticle contrast agent for MRI detection of LN metastasis mediated by CCR2-targeting and demonstrate the potential of monocyte hitchhiking for enhanced nanoparticle delivery.",

Bacterial outer membrane vesicles (OMVs) have received increased attention recently as a potential subunit vaccine. OMVs are non-replicative and contain the principle immunogenic bacterial antigen, which circumvents the safety concerns of live-attenuated vaccines. Here, we developed a novel nano-vaccine by coating OMVs onto PEGylated nano-Rehmannia glutinosa polysaccharide (pRL) in a structure consisting of concentric circles, resulting in a more stable vaccine with improved immunogenicity. The immunological function of the pRL-OMV formulation was evaluated in vivo and in vitro, and the underlying mechanism was studied though transcriptomic analysis. The pRL-OMV formulation significantly increased dendritic cell (DC) proliferation and cytokine secretion. Efficient phagocytosis of the formulation by DCs was accompanied by DC maturation. Further, the formulation demonstrated superior lymph node targeting, contributing to a potent mixed cellular response and bacterial-specific antibody response against Bordetella bronchiseptica infection. Specifically, transcriptomic analysis revealed that the immune protection function correlated with T-cell receptor signalling and Th1/Th2/Th17 differentiation, among other markers of enhanced immunological activity. These findings have implications for the future application of OMV-coated nano-carriers in antimicrobial immunotherapy.",

However, their expression and clinical value in gastric cancer (GC) remain poorly understood. Serum EV RNA was extracted from four patients with GC and four healthy controls, followed by high-throughput RNA sequencing. LncRNAs were further validated in training and validation sets using quantitative real-time reverse transcription polymerase chain reaction. A total of 37,684 lncRNAs were obtained, and 10 lncRNAs were selected based on the criteria (P < 0.05 and |log2FoldChange| \u22651). Serum EV lncRNA RMRP, RPPH1, and linc-ROR were significantly higher in patients with GC than in those with chronic gastritis, atypical hyperplasia, or healthy control (all P < 0.05). Three lncRNAs were also significantly correlated with tumor diameter, lymphatic metastasis, distal metastasis, and TNM stage (all P < 0.05). The area under the curve (AUC) values for lncRNA RMRP, RPPH1, and linc-ROR were 0.727, 0.774, and 0.811, respectively. Corresponding sensitivity and specificity were 63.4% and 85.4%, 50.7% and 89.6%, and 78.5% and 66.7%. The combination of these three lncRNAs with carcinoembryonic antigen (CEA) yielded an AUC of 0.909, with a sensitivity and specificity of 83.3% each. Furthermore, high EV linc-ROR and RMRP expression levels were associated with worse disease-free survival and overall survival (OS). Univariate and multivariate Cox regression analyses confirmed that linc-ROR was the only independent prognostic factor for GC. Finally, the lncRNA-miRNA-mRNA network showed that three lncRNAs were predicted to interact with 15 miRNAs and 69 mRNAs. In addition, lncRNA RMRP and linc-ROR were correlated with immune cell infiltration, including neutrophils, central memory CD4 T cells, macrophage, and natural kill T cells. EV lncRNAs are prospective biomarker and correlated with immune cell infiltration in GC. It provides a foundation for the development of serum EV-targeted novel biomarkers and immunotherapy targets of GC.",

However, their practical applications are hindered by weak immunogenicity and inadequate lymph node targeting. In this study, we engineered tEVs into \"self-adjuvant\" multiantigenic nanovaccines that simultaneously accumulate in tumors and lymph nodes (LNs), effectively triggering innate and adaptive immunity capable of recognizing both tumor cells and virus antigen-modified tumor cells to inhibit tumor progression. 4T1 tumor cells were infected with vesicular stomatitis virus (VSV), leading to the expression of VSVG and calreticulin (CRT) on their surface. Using these infected cells, we prepared extracellular vesicles (vEVs) carrying both VSVG and CRT. When injected subcutaneously, vEVs targeted tumors effectively due to the homologous targeting capability of tumor cell membranes. In which, VSVG induced fusion between vEVs and tumor cells, creating viral antigen-decorated tumor cells, which enhanced the recognition and phagocytosis of tumor cells by macrophages. Additionally, the surface CRT of vEVs activated the \"eat-me\" signaling, thus improving their recognition and uptake by dendritic cells (DCs). This led to DC maturation and the activation of antiviral and antitumor T cells, synergistically inhibiting tumor growth. This research introduces a straightforward yet efficacious methodology for the production of cancer vaccines to fight cancer through the stimulation of both the antiviral and antitumor immune responses within the body.",

However, the immunosuppressive microenvironment of TDLNs propels the formation of pre-metastatic niche, in which the immunocytes are dysfunctional, and the high expression of programmed death-ligand 1 (PD-L1) on dendritic cells (DCs) restricts the activation of cytotoxic T lymphocytes. Herein, engineered exosomes (EmDEX@GA) are developed for locoregional immunomodulation of TDLNs. EmDEX@GA possess CC-chemokine receptor 7 (CCR7) -dependent LN homing capacity and over-expressed programmed cell death protein 1 (PD-1) for immune checkpoint blockade (ICB). The loaded stimulator of interferon genes (STING) agonist can reinforce anti-tumor immunity through STING pathway activation. In orthotopic breast cancer mouse model, local administration of EmDEX@GA remodels the immunosuppressive microenvironment of TDLNs and elicits potent anti-tumor immunity, resulting in the suppression of tumor as well as the reduction of lymph node metastasis and distant metastasis. Compared with systemic ICB, local immunotherapy with EmDEX@GA has better therapeutic efficacy on suppressing distant metastasis. Moreover, the study suggests that the occurrences of distant metastasis are associated with the immunosuppressive microenvironment rather than the metastasis in TDLNs, indicating that targeted immunomodulation of TDLNs is necessary.",

Like other infectious fungal diseases, it becomes even more severe when it affects immunosuppressed patients. This infection has a global distribution and is endemic in some regions of Brazil and it is an important zoonotic public health problem. The disease is caused by a complex of at least four pathogenic species, including Sporothrix brasiliensis. The immunological response against these species has not yet been completely elucidated. Still, structures such as extracellular vesicles could carry important components that can contribute to the modulation and control of this significant infection. Thus, this work aims to analyze the participation of EVs from na\u00efve dendritic cells and EVs from DCs previously primed with S. brasiliensis yeast and primed with EVs from the fungus in the immune response against experimental sporotrichosis in murine models. The groups that received EVs from DCs primed with S. brasiliensis or their EVs showed a significant decrease in fungal load compared to the negative control group. When we analyzed the cytokine profile in the skin of mice treated with EVs before infection, we observed an increase in IFN-\u213d, TNF-\u03b1, IL-17, and IL-10, mainly in animals previously treated with EVs from DCs cultivated with yeast cells. It is worth highlighting that all prophylactic protocols modulated and minimized fungal growth compared to the control; that is, EVs contributed to the control of the infection and acted in favor of the host, demonstrating a protective character.",

Lymph node metastasis (LNM) of in cancer patients indicates poor prognosis and it is an important indication to determine the therapeutic regime. Therefore, more attention should be given to the molecular mechanics of tumor lymphangiogenesis and LNM. Extracellular vesicles (EVs) are nanoscale cargo-bearing membrane vesicles that can serve as key mediators for the intercellular communication. Like Hermes, the messenger of the Greek gods, EVs can be secreted by tumor cells to regulate the LNM process. Many evidence has proved the clinical correlation between EVs and LNM in various cancer types. EVs plays an active role in the process of metastasis by expressing its connotative molecules, including proteins, nucleic acids, and metabolites. However, the clear role of EVs in the process of cancer LNM has not been thoroughly studied yet.

Many factors contribute to this dilemma, including lymphatic metastasis, which is the primary cause of PDAC metastasis. The inhibition of early lymph node metastasis, including the lymphangiogenic process, may be a novel strategy for PDAC treatment. Through miRNA sequencing of plasma extracellular vesicles (EVs) from PDAC patients, for the first time, we identified that plasma EV-miR-205-5p served as a non-invasive biomarker distinguishing lymphatic metastasis status (N0 vs. N2) in PDAC patients. Using tissue microarray and in situ hybridization, we discovered that miR-205-5p was highly expressed in PDAC, but negatively correlated with lymph node metastasis. By in vivo and in vitro experiments, we demonstrated its unique mechanism of action via EV-mediated transfer to human lymphatic endothelial cells (HLECs), leading to systematic downregulation of VEGFA and inhibition of the Akt/Erk pathway, which suppressed lymphangiogenesis. Delivering miR-205-5p via engineered EVs might be a promising strategy to eliminate PDAC lymphatic metastasis and improve prognosis.",

Aluminum and lipid nanoparticles have been used for this purpose, but their accumulation or widespread circulation in the body can lead to adverse effects. In contrast, physical adjuvants, which use physical energy to transiently stress tissues, do not persist in exposed tissues or cause lasting adverse effects. Herein, we investigate the effects of intradermal injection of endotoxin-free ovalbumin (OVA) protein alone without additional adjuvants using a needle-free pyro-drive jet injector (PJI) on tumor vaccination efficacy. Intradermal injection of OVA protein alone using PJI significantly increased OVA-specific CD8+ T cell expansion in the lymph node, although lymph node swelling was much less than when aluminum hydroxide was used. The injection also induced OVA-specific killing activity and antibody production and showed strong CD8+ T cell-dependent prophylactic antitumor effects against transplanted E.G7-OVA tumors. In particular, intradermal injection of the fluorescent OVA protein significantly enhanced its uptake by XCR1+ dendritic cells, which have a strong ability to cross-present extracellular proteins in the skin and draining lymph nodes. In addition, the injection increased the expression of HMGB1, one of the potent danger signals whose expression has been reported to increase in response to shear stress. Thus, intradermal injection of OVA protein alone without any additional adjuvants using PJI induces potent CD8+ T cell-mediated antitumor immunity by enhancing its uptake into XCR1+ dendritic cells, which have a high cross-presentation capacity accompanied by an increased expression of shear stress-induced HMGB1.",

Using micromanipulator-assisted isolation of rare DCCs, single-cell mRNA and DNA sequencing, codetection by indexing immunofluorescence imaging and survival analysis, we identified melanoma-associated chondroitin sulfate proteoglycan (MCSP)+ melanoma cells as metastasis founder cells (MFCs). We found that DCCs entering SLNs predominantly exhibited a transitory phenotype that, upon interferon-\u03b3 exposure triggered by CD8 T cells, dedifferentiated into a neural-crest-like phenotype. This was accompanied by increased production of small extracellular vesicles (sEVs) carrying the immunomodulatory proteins CD155 and CD276 but rarely programmed cell death protein 1 ligand 1. The sEVs suppressed CD8 T cell proliferation and function, facilitating colony formation. Targeting MCSP+ MFCs or their immune escape mechanisms could be key to curing melanoma early by preventing manifestation of metastasis.",

Cancer associated fibroblasts (CAFs), major cell components in the TME, exert significant effects on malignant behaviors of various cancers. Triple negative breast cancer (TNBC) is the most malignant subtype of breast cancer with a high metastatic potential and poorer prognosis. However, the underlying mechanism by which CAFs promote TNBC development has not been sufficiently studied. The study aims to elucidate how CAFs promote TNBC aggressiveness by delivering protein-coding circMIB1 to activate MIB1/DLL4/Notch pathway, and provide a potential clinical biomarker for TNBC management. The oncogenic exosomal circMIB1 with protein-coding potential was identified through high-throughput RNA sequencing and ribosome nascent-chain complex sequencing (RNC-seq). The enrichment of circMIB1 in CAFs was confirmed using in situ hybridization (ISH) and qRT-PCR. The protein-coding capacity of circMIB1 was validated based on the polysome profiling, and luciferase assays. Functional roles of circMIB1 were explored using in vitro and in vivo models, while the underlying mechanism was dissected via co-immunoprecipitation (Co-IP) and western blotting. CAF-secreted exosomal circMIB1 promoted TNBC metastasis and stemness by translating a functional peptide, MIB1-223aa. Mechanistically, MIB1-223aa competitively bound to the E3 ubiquitin ligase RNF213, which blocked the RNF213-mediated K48-linked ubiquitination and degradation of MIB1. Moreover, the stabilized MIB1 enhanced the Notch signaling via a ubiquitination-dependent activation of the ligand DLL4, thereby driving TNBC malignancy. Clinically, high expression of circMIB1 or MIB1-223aa in TNBC tissues was correlated with poor clinical prognosis, as evidenced by reduced overall survival, shortened disease-free survival, and elevated lymphatic metastasis rates. This study provides the first evidence of exosome-transmitted protein-coding circRNAs in CAF-TNBC crosstalk, offering novel insights into the TME-driven metastasis and providing promising biomarker for TNBC management.",

VEGF-C is a major lymphangiogenic ligand that plays a vital role in LN metastasis in PCa. However, in some PCa caseswith LN metastasis,VEGF-C is not upregulated, indicating that some VEGF-C-independent mechanisms are essential for lymphangiogenesis.Herein, we confirmed that extracellular vesicles (EVs) derived from PCa cells could promote LN metastasis in PCa independent of VEGF-C. We identified an EV circular RNA, circPDLIM5, that could promote lymphangiogenesis and lymphatic metastasis in both PCa cell lines and mouse models. Mechanistically, the packaging of circPDLIM5 into EVs was regulated by heterogeneous nuclear ribonucleoprotein A2B1. Subsequently, EVs were transmitted to human lymphatic endothelial cells, and EVs carrying circPDLIM5 could then directly interact with the transcription factor Yin Yang 1 to enhance the expression of Prospero homeobox 1, which is crucial for the formation, differentiation, and maturation of lymphatic vessels. Our findingshighlight the importance of a molecular mechanism mediated by EVs carrying circPDLIM5that is involved in lymphangiogenesis and LN metastasis in PCa; as a result, EVscarrying circPDLIM5 may be an attractive therapeutic target for LN-metastatic PCa.",

Patients planned for breast surgery and SLN biopsy received 0.1\u2005ml SPIO intradermally at the areolar border or over the tumour. Tc99 \u00b1 blue dye was administered per clinical routine. Magnetic, radioactive, or blue nodes were removed and analysed separately. SLN detection and numbers, concordance, and skin discoloration were analysed. A total of 216 patients were included at five hospitals. Median age was 63 years, tumour size 15.9\u2005mm, and 91.7% underwent breast conservation.

An ultra-low dose of 0.1\u2005ml intradermal injection of SPIO was non-inferior to Tc99 \u00b1 blue dye for SLN detection. Skin discoloration was limited and further reduced by removal during surgery. A new magnetic liquid with small particles of iron has been introduced to find the first lymph node in line of the drainage from a breast cancer. The liquid is injected in the breast and the node can be detected with a magnetometer, most often in the armpit. In this study an ultra-low dose of the magnetic liquid was compared to today\u2019s standard, a radioactive liquid. Each patient was injected with both liquids before surgery. It was shown that the very low dose of magnetic liquid was equally good as the standard of today for sentinel lymph node detection. The magnetic liquid is better in some ways, as no radioactivity is needed and it can be injected several weeks before surgery.",

In this study, we investigated a blood-based liquid biopsy assay of exosomal microRNA (miRNA) for the non-invasive detection of LNM in patients with high-risk EGC. Two genome-wide miRNA expression profiling datasets [GSE164174 and The Cancer Genome Atlas (TCGA)] were analyzed to prioritize biomarkers in pretreatment plasma samples from clinical training and validation cohorts of GC patients. An integrated exosomal miRNA panel was developed and a risk stratification model combining the miRNA panel with clinical risk factors was established. Using comprehensive expression profiling of public datasets, we identified a transcriptomic panel of four miRNAs (miR-34b, miR-130a, miR-375, and miR-627) that robustly identified patients with LNM [area under the curve (AUC) 0.86, 95% confidence interval (CI) 0.77-0.92]. We assessed panel performance in a training cohort (AUC 0.86, 95% CI 0.67-0.96) and validated it in an independent validation cohort (AUC 0.83, 95% CI 0.68-0.94). Our risk stratification model was more accurate than the panel and was an independent predictor of LNM identification (AUC 0.94). A novel, non-invasive, liquid biopsy-based method for patients with EGC may predict those conventionally classified as high-risk patients with LNM who are unlikely to benefit from surgical resection.",

Cell surface heparan sulfate proteoglycans (HSPGs), namely, syndecan-1 (SDC1), SDC2, and SDC4, are involved in cancer progression, metastasis, and regulate extracellular vesicles (EVs) biogenesis, including the microvesicles (MVs). This study analyzed MV-enriched EVs isolated from blood plasma of BC patients with negative (n\u2009=\u200919) and positive (n\u2009=\u200920) LNM (nLNM and pLNM, respectively) using differential centrifugation. Western blot analysis revealed significantly elevated SDC2 levels in MV-enriched EVs from pLNM cases compared to nLNM. Additionally, fibronectin (FN), a SDC2-interacting protein identified through STRING analysis, was also upregulated in pLNM MV-enriched EVs. In contrast, qRT-PCR showed reduced SDC2 (P\u2009<\u20090.01) and FN (P\u2009<\u20090.05) mRNA levels in tumor tissues of pLNM patients compared to nLNM. ROC analysis highlighted the diagnostic value of SDC2 (AUC: 0.8376) and FN (AUC: 0.8803) mRNA in differentiating LNM status. Bioinformatics analyses further confirmed the association of SDC2 and FN expression with BC staging and prognosis. These findings underscore the potential of circulating MV-enriched EV-associated SDC2 and FN, along with their tumor tissue mRNA expression, as potential predictive biomarkers for LNM and chemotherapy response in chemotherapy-na\u00efve obese BC patients.",

This study presents a versatile Hybrid-Gel platform that integrates CoQ10-loaded hybrid vesicles with an injectable, pH-responsive hydrogel to enhance localized drug delivery. High-purity nanovesicles are isolated using an optimized ultracentrifugation (UC) and size-exclusion chromatography (SEC) method, then hybridized with liposomes to improve encapsulation and skin penetration. To further optimize localized delivery performance, an injectable binary hydrogel system is then introduced. This hydrogel, formed via Schiff base crosslinking between hyperbranched polyethylene glycol and aldehyde-modified hyaluronic acid (A-HA), exhibits mild gelation conditions, excellent injectability, and strong tissue adhesion. The hydrogel effectively encapsulates hybrid nanovesicles, ensuring enhanced stability, ease of administration, and controlled, pH-responsive release. As a proof of concept, an in vitro permeation test with porcine skin model demonstrates that the hydrogel significantly improves CoQ10 penetration, achieving a more than fourfold increase in transdermal efficiency compared to free CoQ10, suggesting superior bioavailability. This synergistic approach, combining hybrid nanovesicle-mediated drug transport with a dynamic hydrogel matrix, offers a robust and versatile platform for localized transdermal therapy, with potential applications in precision medicine, regenerative treatments, and chronic disease management.",

Single-mode antibacterial approaches often fall short of achieving optimal effects, necessitating the development of combination therapies. To address these challenges, pH-responsive antibacterial nanovesicles, termed DAClLy, are developed by integrating targeting ligand and multiple antimicrobial agents with complementary modes of action to target MDR bacteria with enhanced efficacy while minimizing adverse effects. DAClLy are engineered through the complexation of sulfonium-ion-bearing antibacterial polypeptoids, and primary amine-containing polypeptoids modified with 2,3-dimethyl maleic anhydride, encapsulating lysostaphin, a bacteriolytic enzyme. Upon reaching the acidic microenvironment of bacterial infections, the DAClLy vesicles disassemble, releasing their antimicrobial components. The released lysostaphin degrades bacterial cell walls, while the polypeptoids synergistically disrupt bacterial membranes, resulting in a multi-action bactericidal effect. This synergistic mechanism demonstrates remarkable efficacy against MDR S. aureus, including its resilient biofilm formations. In vivo studies have shown that the DAClLy vesicles exhibit potent antibacterial activity against MDR S. aureus-induced skin and lung infections. The nanovesicles effectively penetrate the lung mucus barrier, addressing both surface-level and deep-tissue infections. By integrating multiple strategies, DAClLy offers a promising therapeutic strategy to combat MDR pathogens across diverse tissue contexts.",

However, it is still unclear how the antigen expressed at the site of vaccination is delivered to draining lymph nodes for activation of the immune system. To address the issue, the current study investigated the role of extracellular vesicles (EVs) in the delivery. Following intramuscular electrotransfection of DNA vaccines encoding a transmembrane antigen, hemagglutinin (HA), EV secretion was significantly increased in the muscle with the peak level being \u223c10-fold higher than the unvaccinated control. More importantly, the EVs were highly enriched with HA, and could reach the draining lymph nodes through lymphatic vessels within 4 h. Blocking the EV secretion by systemic treatment with a small molecular inhibitor, GW4869, significantly reduced humoral and cellular responses against the antigen. These findings indicated that the EVs play an important role in the antigen delivery, suggesting that enhancing local EV biogenesis and antigen packaging into EVs can be new avenues for development of next-generation vaccine adjuvants.",

Here, we developed a pH-responsive cationic nanovesicle (124I/Cy5.5-sO@FCLs), equipped with dual-modal positron emission tomography (PET) and fluorescence imaging capabilities, to enable dynamic monitoring of the role of ribonucleotide reductase M2 subunit (RRM2) disruption in overcoming Osi resistance and enhance targeted anticancer efficacy in NSCLC. RRM2 was identified as a critical driver of poor prognosis and Osi resistance in NSCLC. The 124I/Cy5.5-sO@FCLs enabled real-time tracking of tumor targeting and biodistribution, and CRISPR-Cas9-mediated RRM2 disruption efficiently reversed Osi resistance and potentiated synergistic anticancer effects, which was attributed to counteracting TGF-\u03b2/Smad2/3-mediated epithelial-mesenchymal transition (EMT) and amplifying cGAS/STING-induced ferroptosis. Furthermore, the nanovesicles triggered STING-dependent immunogenic cell death (ICD), stimulating tumor infiltration of dendritic cells (DCs) and T cells; combination with anti-PD-L1 therapy augmented NSCLC regression. Collectively, 124I/Cy5.5-sO@FCLs integrate gene editing with targeted therapies while enabling dynamic, quantitative monitoring, providing an approach for precision-targeted treatment in Osi-resistant NSCLC.",

However, controlling the morphologies of these assemblies is considerably challenging due to their intricate polymorphisms and complex responsiveness to environmental changes. In this study, we present a stoichiometry-controlled strategy to finely tune the morphology of supramolecular nanostructures by coassembling diphenylalanine (FF) with charged aromatic dipeptides. Diverse nanostructures including one-dimensional nanotubes, two-dimensional planar sheets, and three-dimensional nanovesicles are obtained by varying the ratio of two peptide building blocks. These structures are predicted by coarse-grained simulations, subsequently validated for stability by all-atom simulations, and further confirmed by experiments. Notably, planar sheets, rarely seen in FF self-assembly, emerge frequently when coassembling FF with high ratios of charged dipeptides. Interaction analysis reveals that the formation of these diverse nanostructures is driven by aromatic stacking and modulated by the strength of electrostatic repulsion. Remarkably, pH-responsive environments induce transformations between nanovesicles and planar sheets, underscoring their potential for biomedical applications. This study underscores the potential of a stoichiometry-controlled strategy to design multidimensional nanostructures with tunable morphologies, offering significant promise for nanomedicine applications, such as precision-targeted drug delivery systems.",

This study explores the role of miR-155-5p as an oncogenic driver in BC progression through a multi-omics approach. Elevated miR-155-5p expression was observed in serum exosomes and tumor tissues, with its upregulation correlating with advanced pathological stages, lymph node metastasis, and unfavorable clinical outcomes. Functional experiments demonstrated that miR-155-5p enhances cellular proliferation, motility, and invasive capacity while inhibiting apoptosis in BC. Mechanistically, miR-155-5p exerts its effects by directly suppressing Nedd4 Family Interacting Protein 1 (NDFIP1), thereby initiating activation of the NF-\u03baB axis. This activation was characterized by increased nuclear translocation of NF-\u03baB p65 and enhanced secretion of inflammatory cytokines, including IL-6 and TNF-\u03b1. In vivo, knockdown of miR-155-5p effectively suppressed tumor growth and metastasis, with these effects reversed by silencing NDFIP1. These results highlight the miR-155-5p/NDFIP1/NF-\u03baB axis as a critical pathway in BC progression, providing new insights into its molecular mechanisms. miR-155-5p emerges as a promising diagnostic marker and therapeutic candidate, suggesting the feasibility of miRNA-based interventions in BC treatment.

However, the diagnostic potential of exosomes, which carry heterogeneous tumor-derived functional cargo remains largely underexplored. This study aimed to evaluate the diagnostic and prognostic utility of exosomal mRNAs derived from saliva and serum samples of OSCC patients. Exosomes were isolated from paired serum and saliva samples of 40 OSCC patients and 40 healthy controls using commercial kits. Characterization was performed using NTA, TEM, zeta potential, protein/lipid quantification, and western blotting. Expression of nine mRNA markers including cytokines (IL1, IL6, IL8, TNF-\u03b1), proliferation markers (OAZ1, SAT, S100P), and metastasis-related molecules (MMP9, Chemerin) was analyzed by qRT-PCR. Diagnostic accuracy was evaluated using ROC curve analysis, and correlations with tumor grade and lymph node metastasis were systematically investigated. Results demonstrated that salivary exosomal TNF-\u03b1,\u00a0MMP9 and OAZ1 exhibited markedly higher diagnostic sensitivity and specificity compared to the top-performing serum exosomal derived markers (IL1, MMP9\u00a0and OAZ1). Notably, a two-gene salivary mRNA panel combining TNF-\u03b1 and OAZ1 demonstrated strong discriminatory power (AUC: 0.89, sensitivity: 80%, specificity: 90%; Youden Index: 0.70). Additionally, salivary exosomal MMP9, IL8, S100P, SAT, and OAZ1 significantly differentiated between grade I and grade III OSCC. Moreover, IL6 expression positively correlated with lymph node metastasis. In contrast, serum exosomal markers lacked clear discriminatory potential. Therefore, salivary exosomal panel of TNF-\u03b1 and OAZ1 represent promising non-invasive biomarkers for OSCC diagnosis, while MMP9 and IL6 is informative for tumor grading.",
"41185659": "ID: 41185659\nTitle: Prox1 Is Linked to Metastasis and Poor Prognosis by Promoting Lymphangiogenesis in Melanoma.\nAbstract: The purpose of this study is to investigate the role of Prox1 in the progression of cutaneous melanoma (CMM) and its relationship with lymphatic metastasis. By analyzing the data from the Cancer Genome Atlas (TCGA), we found that the expression of Prox1 and LYVE1 was significantly upregulated in the metastatic melanoma group. Additionally, elevated levels of Prox1 were associated with shorter survival times. Correlation analysis demonstrated a significant relationship between Prox1 and markers associated with lymphangiogenesis, including LYVE1, FLT4, FOXC2, and ANGPT2. A clinical study involving 32 cases of CMM was conducted to analyze Prox1 expression and its relationship with lymphangiogenesis and clinicopathological characteristics. Research revealed that Prox1 was expressed significantly higher in patients with lymph node (LN) metastasis and in those classified as stage 3C-4. Additionally, the density of lymphatic vessels(LVD) in the LN metastasis group and the stage 3C-4 group was markedly higher than in the group without lymph node metastasis and in the stage 0-3B group. Furthermore, Breslow thickness was found to correlate with both Prox1 expression and LVD. Prox1-positive expression was associated with increased LVD. Further investigation was conducted on the role of Prox1 in the CMM cell line A375 and its derived exosomes. Exosomes were collected from CMMnc and CMMshProx1 to verify the changes in Prox1 expression, respectively. It was observed that the proliferation, migration, and tube formation abilities of human lymphatic endothelial cells(HLECs) diminished with the downregulation of Prox1. Additionally, VEGFR3 activation was reduced in HLECs following the reduction of Prox1. Prox1\u00a0played an important role in promoting cell proliferation, migration, and lymphangiogenesis, which is related to tumor metastasis and poor prognosis. These results indicated the potential importance of Prox1 as a biomarker, which is expected to lead to the development of a new insight for anti-tumor therapy.",
"41190394": "ID: 41190394\nTitle: Exosomes in cancer metabolism and drug resistance: A review.\nAbstract: The transfer of molecular cargo in exosomes plays a crucial role in cancer progression, influencing metabolic processes, angiogenesis, immune interactions, and invasive capabilities. This review synthesizes current evidence on how exosomes modulate tumor metabolism and drive drug resistance, and outlines therapeutic opportunities. We searched PubMed, Scopus, Web of Science, and Google Scholar for English-language studies using terms related to exosomes/extracellular vesicles, glycolysis, oxidative phosphorylation (OXPHOS), lipid metabolism, and drug resistance/chemoresistance, and integrated the literature qualitatively. Evidence indicates that exosomes reprogram tumor and stromal metabolism by delivering enzymes and non-coding RNAs that boost glycolysis and dampen OXPHOS, activate cancer-associated fibroblasts and extracellular matrix (ECM) remodeling, and modulate ferroptosis. They stimulate angiogenesis (e.g., via vascular endothelial growth factor (VEGF)/Wnt pathways) and promote immune escape through programmed death-ligand 1 (PD-L1), transforming growth factor beta (TGF-\u03b2), and macrophage reprogramming. Exosomal integrins and proteases contribute to epithelial-mesenchymal transition (EMT), organotropism, and pre-metastatic niche formation. Critically, exosomes propagate chemoresistance by exporting drugs and spreading determinants-including P-gp/BCRP/MRP-1, anti-apoptotic proteins, and regulatory RNAs-to previously sensitive cells; adipose-derived vesicles and lipid cargos further reinforce metabolic plasticity and therapy resistance. Given their stability, nanoscale dimensions, and ability to cross the blood-brain barrier, exosomes are promising vectors for targeted delivery; engineered vesicles can enhance chemotherapy responsiveness and counteract resistance, particularly alongside immunotherapy. In summary, interventions that disrupt exosome biogenesis, cargo loading, or uptake-paired with engineered exosomes for precision delivery-could mitigate drug resistance, metastasis, and immune evasion and advance more effective cancer treatment.",

To overcome these limitations, we developed cyclic RGD-decorated solid lipid nanoparticles for integrin-targeted delivery of etoposide, aiming to enhance tumor selectivity and therapeutic efficacy. SLNs were prepared using hot homogenization and ultrasonication, with cyclic RGD peptides conjugated to the surface via non-covalent and covalent strategies. Among three conjugation approaches evaluated, maleimide-based functionalization was selected for its reproducibility, stability, and high coupling efficiency. RGD-functionalized SLNs were physicochemically characterized and assessed for integrin-mediated uptake, cytotoxicity, cell cycle effects, and apoptosis induction in SH-SY5Y (integrin-high) and SK-N-BE(2) (integrin-low) NB cell lines. RGD-SLNs demonstrated efficient peptide conjugation while maintaining colloidal stability and drug loading. Flow cytometry confirmed enhanced uptake in \u03b1v\u03b23 integrin-expressing SH-SY5Y cells, with moderate uptake in SK-N-BE(2) cells. ETP encapsulation within SLNs significantly improved its cytotoxic profile, with RGD functionalization further reducing IC50 values and promoting apoptosis. These findings establish RGD-functionalized SLNs as a promising integrin-targeted platform for ETP delivery in NB.

Lymphatic small extracellular vesicles (sEVs) derived from melanoma play a crucial role in establishing a premetastatic niche (PMN) within the sentinel lymph node (SLN). Therefore, analyzing the proteomic content of tumor-draining lymphatic sEVs that deliver oncogenic signals to the SLN is vital in understanding the PMN. To investigate this, we performed multiplexing (18 samples) using tandem mass tag labeling to profile the lymphatic sEV proteomes obtained from afferent lymphatic channels leading to the SLN of melanoma patients (n = 6), non-cancer-associated afferent lymphatic channels (n = 3), and postoperative lymphatic fluid after LN dissection (n = 9). We identified 595 new proteomic cargoes compared with those reported in ExoCarta and 1003 new cargo proteins relative to three previously reported lymphatic EV datasets. The analysis revealed 145 differentially expressed proteins of melanoma sEVs that link to increased cellular stress and injury pathways and a decrease in extracellular matrix organization (-log[p value] >7.0). Analysis of the top 50 differentially expressed proteins included expressions of normal, primary, and metastatic samples across multiple omics datasets. Hierarchical clustering with postoperative samples demonstrated nine upregulated and two downregulated proteins specific to melanoma sEVs, which are associated with melanoma progression (p < 0.05). Notably, several common proteins associated with melanoma and postoperative samples were related to the wound healing mechanism. The multiplex immunofluorescence analysis of selected proteins reveals significantly increased expression levels of CD38, galectin-9 (LGALS9), and tenascin-C (TNC) in the lymphatic sinuses of SLN (-) compared with the control LN sinuses. Moreover, higher levels of LGALS9 protein in LN tissue are associated with poor overall survival of melanoma patients (p = 0.0018). In summary, this study reveals an altered landscape of sEV proteome in the afferent lymphatic fluid of melanoma, highlighting distinct sEV proteins that are uniquely present in the SLN during PMN development.",

Molecular docking and molecular dynamics simulations revealed strong GAP 5a/p-CA interactions and favorable translocation across lipid bilayers. GAP 5a/p-CA nanovesicles exhibited spherical morphology, a negative surface charge and an average particle size of 306.5\u00a0nm, enabling efficient tumor targeting. Notably, GAP 5a nanovesicles achieved high drug entrapment efficiency (90.7\u00a0%) and pH-responsive release, with faster drug liberation under acidic conditions mimicking the tumor microenvironment. Additionally, in vitro release studies demonstrated a more controlled release of the drug from nanovesicles compared to drug solution. Loading p-CA on GAP 5a nanovesicles resulted in a two-fold increase in the drug's cytotoxicity on Glioma GL261 cancer cells, from IC50 936\u00a0\u03bcg/mL to 451\u00a0\u03bcg/mL, consistent with formulation-dependent effects playing a key role. p-CA and GAP 5a scored high IC50 values on VERO cells implying good safety profile of the prepared novel system.

Plasma samples from 123 patients with CRC and 79 healthy controls (HCs) were collected for this study. Exosomes were extracted from plasma, validated, and tRF-3004a levels were detected using quantitative real-time polymerase chain reaction (qRT-PCR). The correlation between plasma-derived exosomal tRF-3004a expression levels and clinicopathological parameters was analysed using the chi-square test. Receiver operating characteristic (ROC) curve analysis was performed to evaluate the diagnostic performance of plasma-derived exosomal tRF-3004a. The results showed that compared with HCs, plasma-derived exosomal tRF-3004a was significantly elevated in patients with CRC and decreased after surgery. Moreover, high tRF-3004a expression was significantly associated with lymph node metastasis, tumour node-metastasis staging, carcinoembryonic antigen (CEA) levels, and nerve/vascular invasion in patients with CRC. ROC analysis revealed that plasma-derived exosomal tRF-3004a demonstrated promising diagnostic utility for CRC, with an area under the curve (AUC) of 0.819 (sensitivity, 0.691; specificity, 0.861).

In this study, we developed a dual strategy for augmenting subunit-vaccine-induced immune responses by integrating self-adjuvanting gold nanoparticle (GNP)-antigen conjugates with implantable chitosan (CS) microneedles (MNs) to achieve sustained intradermal antigen exposure. Conjugation of a model antigen, namely, ovalbumin (OVA), onto the GNP surface (GNP-OVA) resulted in virus-mimicking multivalent antigen display, which substantially enhanced dendritic cell maturation, as evidenced by the upregulation of CD86 and major histocompatibility complex class II. This conjugation strategy also enabled the efficient codelivery of the antigen and carrier into the same antigen-presenting cells, thereby facilitating improved antigen presentation. Furthermore, compared with free OVA and a physical GNP/OVA mixture, conjugated GNP-OVA exhibited considerably longer lymph node retention, primarily because of its nanovaccine properties, which facilitate its preferential trafficking into lymphatic vessels and its subsequent accumulation in lymph nodes. Encapsulation of GNP-OVA into CS MNs (i.e., GNP-OVA MNs) resulted in reliable skin implantation, sustained intradermal antigen exposure, and local immune cell recruitment. Rat immunization studies revealed that GNP-OVA MNs induced balanced T helper 1 and T helper 2 responses and elicited considerably higher and more durable OVA-specific immunoglobulin G levels than did subcutaneous vaccination with GNP-OVA or OVA alone. These responses persisted for at least 16 weeks, highlighting the potential of the developed platform for prolonged subunit vaccine immunization. This dual-strategy platform, combining virus-mimicking GNP-based nanovaccines with immunostimulatory CS MNs, reduces reliance on external adjuvants and enhances the potency and durability of subunit vaccines. Its modular and patient-friendly design underscores its high potential for advancing the development of next-generation vaccines against emerging infectious diseases.",

Restoring lymphatic function offers a promising preventive strategy against early-stage AD pathology. This study aimed to evaluate the effects and mechanisms of Cerebralcare Granule\u00ae (CG), a traditional Chinese medicine formula, on cognitive impairment and pathological markers in AD mouse models by modulating intracranial lymphatic clearance pathways. Six-month-old APP/PS1 transgenic mice and wild-type controls received oral administration of CG or donepezil for two months. Behavioral assessments included the Morris water maze, open field, Y-maze, novel object recognition, and passive avoidance tests. Immunohistochemistry, immunofluorescence, and Western blot analyses were used to assess A\u03b2 deposition, glymphatic clearance, astrocytic aquaporin-4 (AQP4) polarization, meningeal lymphangiogenesis, and blood-brain barrier integrity. Tracer-based in vivo imaging confirmed improved CSF influx and efflux dynamics. Brain-penetrant compounds of CG were identified using UPLC-MS/MS, MALDI-TOF-MS imaging, and network pharmacology. CG treatment significantly improved cognitive performance, reduced A\u03b2 burden, enhanced glymphatic transport, and promoted meningeal lymphatic drainage in APP/PS1 mice. CG restored perivascular AQP4 polarization, improved cerebrospinal fluid-interstitial fluid exchange, facilitated waste removal to cervical lymph nodes, and protected the integrity of the blood-brain barrier. Major brain-penetrant compounds-paeoniflorin, rhynchophylline, and ethyl gallate-were found to target lymphatic signaling pathways (AQP4, VEGFC, VEGFR3, PROX1) effectively.

Plant-derived exosomes (P-Exos)-a unique class of bioactive nanovesicles enriched in regulatory miRNAs, lipids, proteins, and phytoactive metabolites-have emerged as promising natural modulators capable of enhancing osteogenic differentiation, suppressing excessive osteoclast activity, promoting angiogenesis, and mitigating inflammation. Intelligent hydrogels, with their tunable physicochemical properties, high biocompatibility, and extracellular matrix-mimicking architecture, provide a versatile platform for stabilizing P-Exos and achieving controlled, spatiotemporally regulated release. This review systematically summarizes the biological characteristics of P-Exos and elucidates their roles in orchestrating osteoporotic bone repair. Particular emphasis is placed on the design principles of environmentally responsive hydrogels-including thermosensitive, pH-responsive, photocrosslinkable, and other stimuli-adaptive systems-and their capacity to efficiently encapsulate and precisely deliver P-Exos. Furthermore, the synergistic effects of P-Exos-hydrogel composites in modulating the osteoimmune microenvironment, reinforcing angiogenesis-osteogenesis coupling, and accelerating functional bone regeneration are highlighted. Finally, the review addresses the major challenges that impede clinical translation, including the lack of standardized large-scale production of P-Exos, incomplete pharmacokinetic profiles under hydrogel-mediated release, and limited long-term in vivo data.

While physical exercise is known to improve cognitive function and reduce AD risk, its effect on the mLym system and downstream AD pathology have not been fully elucidated. METHODS: Three-month-old 5xFAD mice underwent a 3-month wheel-running exercise regimen. The function of the mLym system was assessed before and after exercise using high-frequency ultrasound imaging with nanoparticle tracers to monitor CSF drainage to deep cervical lymph nodes. The study evaluated changes in mLym vessel structure, A[Formula: see text] deposition, and cognitive performance. Additionally, the effects of serum and extracellular vesicles (EVs) from exercised rats on the expression of lymphatic vessel-related genes (LYVE-1, VEGFR3, and VEGF-C) were examined in lymphatic endothelial and microglial cell lines. RESULTS: Compared to 3-month-old 5xFAD mice and age-matched wild-type controls, 6-month-old 5xFAD mice displayed progressive decline in mLym function, reduced vessel integrity, and increased amyloid plaque burden, accompanied by impaired learning and memory. These changes were associated with decreased expression of LYVE-1 and VEGFR3 in the meninges and VEGF-C in the brain. Exercise intervention reversed these deficits, restoring mLym function and vessel structure, enhancing A[Formula: see text] clearance, and improving cognitive performance. Surgical ligation of mLym vessels accelerated amyloid accumulation and removed the exercise-induced benefits, underscoring the system\u2019s importance in A[Formula: see text] removal. In vitro, A[Formula: see text] oligomers suppressed VEGFR3 and VEGF-C expression, while serum and EVs from exercised rats counteracted this effect. Proteomic analysis of EVs from exercised animals revealed upregulation of CD9, suggesting a link to VEGFR3 signaling. CONCLUSIONS: This study demonstrates that A[Formula: see text] oligomers impair mLym function, exacerbating amyloid pathology. Exercise preserves the structure and function of the mLym system, promoting A[Formula: see text] clearance and mitigating AD progression. These findings highlight the therapeutic potential of targeting the meningeal lymphatic system to slow or prevent AD.",

Salivary microRNAs (miRNAs), particularly exosome-derived miRNAs, have emerged as promising non-invasive biomarkers for early detection and prognostic assessment. This systematic review evaluated the diagnostic and prognostic value of free and exosomal salivary miRNAs in OSCC and HNSCC. A comprehensive search of PubMed, Scopus, Web of Science, and Google Scholar was conducted for studies published between January 2008 and May 2025. Studies assessing salivary miRNAs in histologically confirmed OSCC/HNSCC using validated molecular techniques were included, with quality assessed using QUADAS-2. Forty-two studies encompassing 2577 patients/samples were analyzed. Several miRNAs, including miR-21, miR-31, miR-1307-5p, and miR-486-5p, demonstrated high diagnostic accuracy (AUC > 0.85), while others were significantly associated with lymph node metastasis, treatment response, and survival outcomes. Exosomal miRNAs generally showed superior stability and predictive performance compared with free miRNAs. However, substantial methodological heterogeneity was observed. Overall, salivary miRNAs-particularly exosomal-represent promising biomarkers for OSCC and HNSCC, although standardized protocols and large-scale validation studies are required for clinical translation.",

However, current methods are unsuitable for routine use because of low accuracy and complexity. In this study, we developed a universal detection platform based on a G-quadruplex@DNA nano-highway network (G4@DNA-NHWN). This platform used aptamer-triggered hybridization chain reaction and streptavidin-biotin crosslinking to construct a protein-scaffolded DNA nanostructure enriched with split G4 via a one-pot method at room temperature, enabling sensitive and rapid detection of exosomes. Vimentin, a protein overexpressed in exosomes during the progression and metastasis of breast cancer, was selected as an example. Vimentin binding to the aptamer in G4@DNA-NHWN induces structural disassembly, preventing the split G4 from forming G4-Pb2+ complexes with Pb2+, thereby increasing the free Pb2+. Electrochemical (EC) detection enabled the homogeneous quantification of vimentin by directly distinguishing the EC signal differences between the inert G4-Pb2+ complex and Pb2+. The results demonstrated that this system achieved exosomes detection with a sensitivity as 30 particles/mL within 1 h, and exhibited excellent selectivity. Validation across 42 clinical samples demonstrated a concordance rate of >\u00a090% with the clinical diagnoses. As a DNA-functionalized nanomaterial platform, this system holds the promise of approaches in targeted drug delivery and other biomedical applications beyond biosensing.",

Exosomes-nano\u2011sized extracellular vesicles (30-150\u202fnm) secreted by diverse cell types-have emerged as promising candidates for cancer diagnosis and therapy due to their inherent biocompatibility, low immunogenicity, and ability to cross biological barriers. A comprehensive review of recent literature was conducted to summarize advancements in exosome biology, isolation techniques, and engineering strategies relevant to cancer nanomedicine. Particular emphasis was placed on ESCRT (Endosomal Sorting Complex Required for Transport) dependent biogenesis mechanisms, molecular cargo profiling, and applications in targeted drug delivery. Tumor\u2011derived exosomes play multifaceted roles in cancer progression, including modulation of the tumor microenvironment, facilitation of metastasis, and induction of therapeutic resistance. Their molecular cargo-comprising proteins, lipids, and nucleic acids-serves as a dynamic reflection of the physiological or pathological status of the tumor cells. Technological innovations in exosome isolation, surface modification, and therapeutic payload loading have markedly improved targeted delivery and preclinical treatment outcomes. Notably, drug\u2011loaded exosomes demonstrate the ability to circumvent multidrug resistance. Exosomes hold substantial promise for precision oncology through enhanced drug delivery and diagnostic applications. However, clinical translation requires standardized manufacturing, comprehensive safety profiling, and scalable production methods to address current limitations. Emerging strategies such as exosome mimetics and AI\u2011assisted production optimization poised to address these limitations, guiding the development of personalized, efficient, and targeted cancer treatments.",
"41616889": "ID: 41616889\nTitle: Engineered acid-regulating liposomal nanovesicles for synergistic photodynamic pyroptosis and immunotherapy.\nAbstract: Gasdermin-mediated pyroptosis has emerged as a promising mechanism in cancer immunotherapy, however, its efficacy is often limited by inefficient activation within the immunosuppressive tumor environment. Herein, we generated an acid-regulating biomimetic liposomal nanovesicle (L-P-Cn-U) for the co-delivery of a photosensitizer prodrug (P-Cn) and a carbonic anhydrase IX (CAIX) inhibitor (U-104). By conducting efficacy screening of various P-Cn prodrugs within the L-P-Cn-U system, we identified L-P-C16-U with identical lipid tail structures, as the optimal candidate due to its strong colloidal stability and reactive oxygen species (ROS) generation efficiency. Our cellular and murine model studies demonstrated that L-P-Cn-U-mediated pyroptosis and immunogenic cell death could convert immunologically cold tumors into hot tumors, thereby enhancing antitumor immunity and concurrently inhibiting tumor cell migration. Mechanistic investigation revealed that the acid-triggered U-104 release from L-P-Cn-U augmented intracellular acidity through CAIX inhibition, which subsequently attenuated PI3K-Akt/mTOR signaling. This result enhances O2-dependent ROS production and establishes a negative feedback loop for CAIX expression. Collectively, our findings provide a combinatorial strategy that integrates pyroptosis-focused therapy with metabolic regulation, offering a broadly applicable conception to augment cancer immunotherapy. STATEMENT OF SIGNIFICANCE: Herein, we report the rational design and synthesis of a new class of biomimetic liposome by integrating chemically engineered pH-responsive lipids (L-pH) with lipid-like photosensitizer prodrugs (P-Cn). Characterization studies demonstrated an optimal construct (L-P-C16) with identical lipid tails, showing robust stability and reactive oxygen species production. This optimized nanovesicle was subsequently co-loaded with the carbonic anhydrase inhibitor U-104. The resulting L-P-C16-U system was adequately investigated and shown to effectively synergize photodynamic therapy and immunotherapy. Our work provides new insights into liposome engineering strategies for combination tumor therapy.",

Here, we uncover the role of the insulin-like growth factor (IGF) signaling pathway in zebrafish lymphatic vessel development. We demonstrate that the medial facial lymphatic (MFL) vessel requires cartilage of the hyoid arch for development and identify pregnancy-associated plasma protein A2 (pappa2) as a possible candidate for mediating the cartilage-lymphatic interaction. Pappa2 encodes a secreted metalloprotease that cleaves IGF-binding proteins (IGFBPs; Igfbp3 and Igfbp5b) also expressed near the hyoid cartilage. Overexpression of IGFs and inhibition of IGFBPs enhance MFL growth, while pappa2 knockdown, overexpression of Igfbp3/Igfbp5b, or inhibition of IGF1R inhibit MFL growth. We show that Igf signaling has a cell-autonomous role in zebrafish lymphatic development and that induced pluripotent stem cell (iPSC)-derived human LECs express IGF1R and migrate in response to IGF2. Our data highlight the importance of the IGF signaling pathway in lymphatic-vessel development.",

This study investigated the therapeutic potential of Plant-Derived Exosome-like Nanoparticles (PELNs), particularly those from Poria cocos-Derived Exosome-like Nanoparticles (PcELNs), in treating lymphedema. We isolated PELNs from five botanical sources and found that PcELNs exhibited superior efficacy in alleviating lymphedema symptoms in a mouse model. Multi-omics analyses (transcriptomic, proteomic, metabolomic) revealed that PcELNs induce metabolic reprogramming in human foreskin fibroblasts (HFFs), shifting cell metabolism from glycolysis towards mitochondrial oxidative phosphorylation. This shift may be mediated through enhancing amino acid metabolism and TCA cycle flux, ultimately increasing oxidative phosphorylation. Furthermore, PcELNs reversed TGF-\u03b2-induced pro-fibrotic activation, promoting a matrix-remodeling phenotype. In vivo, PcELNs significantly ameliorated lymphedema by upregulating matrix metalloproteinases (MMP1a, MMP3) and improving mitochondrial function. Our findings demonstrate that PcELNs represent a novel and effective nanotherapeutic strategy for lymphedema by orchestrating metabolic reprogramming and inhibiting fibrosis.",
"41746105": "ID: 41746105\nTitle: Comparison of Immune Cell Transfection by Different Vaccine Vectors After Intradermal Injection.\nAbstract: Background/Objectives: Antigen presenting cells (APCs) and immune cells have unique properties to drive or suppress immune responses. They are therefore key targets for the expression of vaccine antigens or transgene proteins. To better determine the utility of different molecular therapies to modify these cells, mRNA and DNA-based molecular therapy vectors were compared for their ability to genetically modify immune cells after intradermal injections in mice. DNA-based vectors included naked plasmid DNA, plasmid packaged in lipid nanoparticles (LNPs), and replication-defective adenovirus (Ad) vectors. mRNA delivery was mediated by packaging into LNPs like those used in COVID-19 vaccines. Methods: Each vector was used to deliver Cre recombinase into Cre reporter mice whose cells were activated to express green fluorescent protein (GFP) and firefly luciferase after Cre recombination. The mice were injected intradermally (ID) near the base of their tail at a site that drains into the inguinal lymph node. Luciferase activity was imaged in the living mice 1 or 4 days after vector injection. The animals were then euthanized, and luciferase activity was imaged in the draining inguinal lymph node. Cells were prepared from the intradermal injection site and from the draining lymph node to determine which immune cells were genetically modified by phenotyping CD45, CD3, and CD11b GFP-positive cells by flow cytometry. Given that the skin uniquely contains Langerhans dendritic cells, these CD207+ cells were also phenotyped in skin samples and in the draining lymph node. Results: In both the skin and in the draining lymph node, the rank order of luciferase and GFP activation by the vectors were: (1) Ad; (2) mRNA-LNP; (3) DNA-LNP; and (4) naked DNA. Only mRNA-LNP and Ad vectors mediated obvious luciferase activity in the living animals and in the draining lymph nodes by imaging. Notably, both vectors appeared to leak from the ID injection site and not only modify the draining lymph node but also strongly modify the livers of the mice. Naked DNA and DNA-LNP mediated detectable GFP activation in the skin and draining lymph node in some mice, but this activity was low and did not reach statistical significance when compared to PBS-treated animals. mRNA-LNPs and Ad both mediated significant Cre delivery in CD45+, CD3+, CD11b+, and CD207+ immune cells in the skin and in the lymph node, with adenovirus mediating consistently higher levels of expression in all of the tested cells. Conclusions: These data indicate that mRNA-LNP and Ad vectors mediate stronger modification of skin and lymph node immune cells after intradermal injections. Naked DNA and DNA-LNPs were markedly less potent at this activity than the other vectors. These data are consistent with the higher vaccine potency of mRNA-LNP and Ad vectors and suggest that approaches that increase targeting of immune cell subsets may have utility to increase efficacy while also reducing off-target modification of tissues like the liver.",

Increasing evidence suggests that exosomal circular RNAs (circRNAs) could serve as promising novel biomarkers for colorectal cancer (CRC) detection. However, diagnostic potential of exosomal circRNAs in CRC metastasis remain largely underexplored. Methods. The differentially expressed circRNAs (DEcircRNAs) were screened through GSE159669 and GSE205643 datasets. Seventy patients with CRC and seventy age- and sex-matched healthy controls were retrospectively enrolled in this study. The expression of DEcircRNAs was validated in paired cancer and paracancerous tissues, as well as in serum and serum-derived exosomes by RT-qPCR. The clinical significance, prognostic, and diagnostic efficacy of DEcircRNAs were evaluated through chi-square test, Kaplan-Meier survival curves, Cox regression model analysis, and receiver operating characteristic curves. The effect of DEcircRNAs on CRC cell migration and invasion was assessed through wound healing and transwell assays with gain- and loss-of-function methods. Results. A total of six DEcircRNAs were identified, among which only hsa_circ_0005692 exhibited consistent upregulation in cancer tissues, serum, and serum-derived exosomes from patients with CRC. Increased exosomal hsa_circ_0005692 was positively associated with lymph node metastasis and distant metastasis. Patients with elevated levels of exosomal hsa_circ_0005692 exhibited lower overall survival and progression-free survival rates, and exosomal hsa_circ_0005692 was identified as an independent risk factor for poor overall survival. Notably, exosomal hsa_circ_0005692 showed superior diagnostic accuracy than its expression in tissues and serum counterparts in differentiating not only CRC patients from healthy controls, but also metastatic patients from non-metastatic patients. Moreover, hsa_circ_0005692 was found to facilitate CRC metastasis by promoting cell migration and invasion as well as epithelial-mesenchymal transition. Conclusion. This study provides preliminary evidence that serum exosomal hsa_circ_0005692 may serve as a potential biomarker for predicting metastasis in CRC patients, and functionally facilitates CRC metastasis. However, larger-scale confirmatory studies and external validation are still required to substantiate this conclusion.",

Plant-derived nanovesicles have emerged as natural, biocompatible nanomedicines with potential applications in cancer therapy. Here, we systematically screened nanovesicles from ten medicinal plants and identified Panax notoginseng-derived nanovesicles (PnNVs) as the most potent inhibitors of OSCC. PnNVs exhibited favorable safety profiles and intrinsic tumor-homing ability, selectively accumulating in orthotopic tongue tumors. In vivo, they markedly suppressed primary tumor growth and lymphatic metastasis. Mechanistically, PnNVs disrupted redox homeostasis by inhibiting the p38-MAPK/NRF2 signaling pathway, thereby inducing ferroptosis, autophagy, and PANoptosis. In addition, PnNVs impaired cancer cell migration by modulating chemokine-associated signaling pathways critical for tumor dissemination. Multi-omic analyses further revealed synergistic contributions of RNA cargos and metabolite components to their multi-target anticancer efficacy. Collectively, our findings establish PnNVs as a natural, multifunctional therapeutic candidate with dual anti-proliferative and anti-metastatic activity, providing a promising preclinical strategy for OSCC treatment.",

In parallel, plant-derived nanovesicles (PD-NVs) have emerged as natural nanocarriers that transport bioactive cargos capable of modulating recipient cell functions across kingdoms. In this study, Rosa damascena derived nanovesicles (RD-NVs) were isolated by ultracentrifugation and characterized by Transmission electron microscopy, nanoparticle tracking analysis, zeta potential measurement, and SDS-PAGE to confirm their vesicular nature, size distribution, and protein cargo profile. LC\u2012MS/MS-based proteomics, followed by annotation against NCBI and UniProt, and comparative BLASTP mapping to plant and human proteins, revealed 75 proteins shared with plant, Arabidopsis and human orthologs, which were further analyzed using interaction networks and hub detection together with GO and KEGG enrichment. RD-NVs (size, 40-100\u2009nm; surface charge, -25 to -40\u2009mV) carry proteins involved mainly in plastid transcription, ribosomal function, and photosynthetic electron transport in plants, whereas human mapped orthologs were enriched in oxidative phosphorylation, mitochondrial function, arginine-proline, taurine, and hypotaurine metabolism, suggesting that RD-NV hub proteins may interfere with metabolic pathways associated with obesity, insulin resistance, fatty liver, type 2 diabetes, and related inflammatory and neuroinflammatory disorders. Moreover, the peptides of the RD-NVs revealed similarities with multiple reported antimicrobial peptides therefore, might actively participate in plant and human defense system. Overall, this study reveals that the RD-NV proteome contains conserved pathways that may support metabolic and immune-related functions in cross-kingdom contexts. To validate cross-kingdom interaction in vitro, the RD-NVs were treated with the RAW264.7 macrophage which showed significant biocompatibility with a particle range of up to 8.94\u2009\u00d7\u2009108 and cellular internalization.",

Toward that end, we engineered BIO-GEM, a hierarchically structured biomimetic lymph node (bLN) platform comprising genipin-crosslinked gelatin microspheres (GEM) encapsulating deformable albumin-hitchhiking nanoemulsions (BIO, generated with bovine albumin, imiquimod adjuvant, and OVA antigen). Compared to conventional microparticles used for immune cell recruitment, BIO-GEM forms antigen-rich depots that better recruit antigen-presenting cells (APCs) and T cells, creating an immunostimulatory niche for in situ T-cell priming. Collagenase-responsive degradation of GEM triggers sustained release of BIO, which targets LNs via the albumin-hitchhiking pathway. This spatiotemporal delivery strategy synergizes bLN-resident immune activation with LN-directed antigen trafficking, yielding high CD8+ T-cell infiltration at injection sites, dendritic cell maturation, and elicitation of antigen-specific cytotoxic T cells. In multiple B16 murine melanoma models, BIO-GEM significantly suppressed tumor growth and extended the survival of mice. Intradermal vaccination was more efficacious than subcutaneous or intramuscular injection routes.",

In gastric cancer (GC), we identify TAGLN2 as a key exosomal mediator. It is co-overexpressed in GC cells and tumor-associated endothelial cells (TECs), and its high endothelial expression correlates with lymph node metastasis and poor prognosis. Functionally, GC-derived exosomes deliver TAGLN2 to endothelial cells (ECs), orchestrating angiogenesis, EndoMT, and the disruption of endothelial junctions. In vivo, exosomal TAGLN2 accelerated tumor growth and lung metastasis by generating abnormal, leaky vasculature and hypoxia. Mechanistically, exosomal TAGLN2 initiates a novel signaling axis: it transcriptionally upregulates NRP1 via c-Jun/SP1 and concurrently induces SEMA4D expression. TAGLN2 then interacts with both NRP1 and SEMA4D to nucleate a stable cytoplasmic ternary complex. This complex dually activates YAP by competitively disrupting NRP1-YAP binding to release YAP from cytoplasmic retention, and simultaneously suppressing Hippo-mediated degradation, operating independently of the canonical SEMA4D-PlexinB1-RhoA/ROCK pathway. Therapeutically, targeting the TAGLN2 axis synergized with both cisplatin and bevacizumab, potently suppressing tumor progression by impairing neovascularization and promoting vascular normalization. Clinically, exosomal TAGLN2 levels were significantly elevated in GC patient serum. Our study delineates a complete exosome-to-vasculature signaling axis and positions TAGLN2/NRP1/SEMA4D/YAP module as an integrated diagnostic and therapeutic target against metastatic GC.",

However, conventional biomaterials are often constrained by poor biocompatibility and unpredictable degradation behavior. Engineered short peptides, typically comprising 2-50 amino acids, offer a promising solution for vessel regeneration through direct receptor engagement independent of exogenous cargo delivery. These peptides regulate cellular behavior through four key principles: sequence engineering, structural control, functional integration, and dynamic responsiveness. In angiogenesis, short-peptide biomaterials have demonstrated notable progress by enabling receptor-specific activation, multifunctional synergy, and the precise recognition of pathological microenvironments. Although studies on lymphatic regeneration remain limited, advances in identifying targeting sequences and mechanisms of lymphangiogenesis provide a foundation for peptide-based therapeutic strategies. Preclinically, short-peptide systems have shown therapeutic potential in cardiovascular, metabolic, and lymphatic disorders including acute myocardial infarction and diabetic complications. Furthermore, integration with artificial intelligence and 3D bioprinting is expanding the functional versatility of peptide-based biomaterials. Despite these advances, critical challenges remain, including limited predictability of sequence-structure-function relationships, stability-activity trade-offs in peptide modification, the underdevelopment of lymphangiogenic peptides, and barriers to scalable manufacturing and regulation.

Extracellular matrix (ECM) remodeling aways accompany with chemotherapy, but its role in chemotherapy-associated metastasis is still unclear. Here, we reveal hyaluronidase-driven degradation of hyaluronic acid (HA) as a key mechanism underlying chemotherapy-associated lymphatic metastasis in gastric cancer. We found that chemotherapy-associated lymphatic metastasis of gastric cancer occurred during neoadjuvant chemotherapy in both patients and nude mice. The proportion of HA increased significantly in ECM during chemotherapy. We also found that cell migration inducing hyaluronidase 2 (CEMIP2) is the most highly expressed hyaluronidase to degrade HA into its effective type, low molecular weight HA (LMWHA), and promoted chemotherapy-associated lymphatic metastasis of gastric cancer. Mechanistically, CEMIP2-generated LMWHA activates CD44-ATF3 signaling to transcriptionally upregulate TGF\u03b2 receptor TGFBR1, driving metastasis. CEMIP2 is highly expressed in gastric epithelium naturally. To specifically target CEMIP2 and inhibit chemotherapy-associated lymphatic metastasis of gastric cancer, we developed bioengineered RGD-conjugated exosomes mimics (EMs) for targeted delivery of CEMIP2 siRNA. This strategy potently suppressed chemotherapy-associated lymphatic metastasis in vivo. Crucially, our results position CEMIP2 as a therapeutic target to inhibit chemotherapy-associated metastasis of gastric cancer.",

This review emphasises the essential function of extracellular vesicles (EVs) within this communication network. Tumour-derived EVs (TEVs) not only induce epithelial-mesenchymal transition (EMT) by reprogramming breast cancer cell gene expression networks, thereby enhancing migratory and invasive capabilities, but also serve as a 'vanguard', arriving in the lungs in advance to educate stromal cells and establish a pre-metastatic niche that facilitates breast cancer progression. This review uniquely conceptualises EV-mediated EMT and niche formation as a synergistic and sequential biological continuum. We comprehensively examine the sorting mechanisms of EV molecular cargo, targeted delivery approaches, and hierarchical regulatory networks. Critically, we propose that the concurrent regulation of EMT and niche formation is likely driven by the synergistic action of distinct EV subpopulations rather than single 'multitasking' vesicles. Future investigations dissecting this heterogeneity will be pivotal for verifying this synergistic subpopulations hypothesis and establishing a theoretical basis for precise EV-based metastasis intervention strategies.",

Recent findings indicate that tumor-derived exosomal cargo, including PIWI-interacting RNAs (piRNAs), may serve as promising cancer-specific biomarkers. Our study investigates the potential of serum-derived exosomal piRNAs for early detection of endometrial cancer. Biomarker development involves 3 phases with independent patient cohorts. In the discovery phase, small RNA sequencing identified candidate exosomal piRNAs from serum samples of 5 healthy controls and 6 patients with endometrial cancer. In the training phase, a serum exosomal piRNA panel was created using receiver operating characteristic curve, logistic regression, a random forest algorithm, and the DeLong test. In the validation phase, we verified the diagnostic performance of the 3piRNA_panel using the receiver operating characteristic curve. In validation, the 3piRNA_panel (hsa_piR_009183, hsa_piR_014592, and hsa_piR_006767) showed high diagnostic accuracy for endometrial cancer, with an area under the curve of 0.942. It distinguished stage IA endometrial cancer from healthy controls with an area under the curve of 0.977 and was effective in patients with normal CA125 levels. It also potentially differentiated stage IA endometrial endometrioid carcinoma from atypical endometrial hyperplasia. A post-operative decrease in panel scores was observed in a limited subset of paired samples. The expression of hsa_piR_014592 was significantly associated with aggressive histopathological types, \u226550% myometrial invasion, substantial lymphovascular space invasion, lymph node metastasis, p53 mutation, and G3 endometrial endometrioid carcinoma.

Characterization revealed TDEs@ZIF-8@TGF\u03b21siRNA nanoparticles exhibited a well-defined nanostructure with a high TGF-\u03b21 siRNA encapsulation efficiency of 64.73%. Additionally, the system exhibited pH-responsive release and lysosomal escape capabilities, significantly enhancing siRNA stability and cellular uptake efficiency. In vitro, TDEs@ZIF-8@TGF\u03b21siRNA effectively inhibited hepatic stellate cells (HSCs) activation, reducing TGF-\u03b21, Collagen I, and CTGF mRNA levels by 78.6%, 72.1%, and 69.4%, respectively.

Mechanistically, the therapeutic effects were mediated through TGF-\u03b21 gene silencing and consequent inhibition of the TGF-\u03b2/Smad pathway, resulting in attenuated HSCs activation and diminished collagen deposition. These findings indicate that TDEs@ZIF-8@TGF\u03b21siRNA represents a promising biomimetic strategy for targeted gene therapy in liver fibrosis.",

Plant-derived nanovesicles have emerged as safe, biocompatible biomaterials with therapeutic potential for bone regeneration. In this work, the biological effects of Panax ginseng-derived nanovesicles (PNVs) were evaluated with a focus on osteoblast differentiation, bone formation, and mineralization. PNVs were successfully isolated, characterized, and tested for their osteogenic capacity using MC3T3-E1 cells, mouse primary osteoblasts, and osteoclasts. Treatment with PNVs (0-10\u00a0\u03bcg/mL) for 3 or 7 days markedly promoted osteoblastic maturation and matrix mineral deposition, as confirmed by Alizarin-red and Von Kossa staining. In addition, PNVs exposure upregulated key osteogenic genes, including Runx2, ALP, and OPN, while activating major signaling cascades such as BMP2/4 and phosphorylated p38, implying their involvement in osteogenic regulation. Moreover, in an ovariectomized (OVX) mouse model, oral administration of PNVs improved bone microarchitecture by stimulating osteoblast-driven bone regeneration and attenuating osteoclast-mediated bone degradation. Collectively, our findings indicate that PNVs promote osteoblast differentiation and bone matrix formation, thereby enhancing mineralization and demonstrating their potential as a natural nanotherapeutic approach for osteoporosis prevention and treatment.",

Despite its clinical significance, the cellular and molecular mechanisms driving metastatic progression remain inadequately characterized, particularly the role of intercellular communication mediated by tumor-derived exosomes. We analyzed single-cell RNA sequencing (scRNA-seq) on primary and metastatic PTC tissues (n=12 samples from 4 patients), exploring cellular heterogeneity and distinct subpopulations. Metastasis-associated cell states (Scissor+ and Scissor-) were delineated using the Scissor algorithm. Pathway activity in these subpopulations was analyzed using the PROGENy algorithm.Exosomal proteomic data from lymph node metastasis patients were cross-referenced with Scissor+ signatures, identifying candidate proteins. Functional validation included in vitro angiogenesis assays with HUVECs and in vivo xenograft models to assess tumor growth and vascularization. ScRNA-seq revealed significant tumor cell heterogeneity between primary and metastatic sites, with Scissor+ cells strongly linked to metastatic phenotypes. PROGENy analysis demonstrated significant upregulation of VEGF signaling in Scissor+ cells. Among six key proteins identified, PDLIM1 was highly expressed in PTC cell lines and metastatic tissues (P < 0.001). Tumor-derived exosomal PDLIM1 was internalized by endothelial cells, enhancing angiogenesis in vitro. PDLIM1 knockdown in exosomes suppressed HUVEC tube formation (P < 0.05) and reduced tumor volume, CD31+ microvessel density, and LYVE-1+ lymphatic vessel density in xenografts (P < 0.05). Our study suggests that exosomal PDLIM1 may play a role in promoting angiogenesis and primary tumor progression in PTC. These findings provide preliminary insights into the potential involvement of exosome-mediated intercellular communication in PTC pathogenesis. Further validation in larger cohorts and functional studies, including rescue experiments, are warranted to evaluate whether targeting PDLIM1 could represent a viable therapeutic strategy.",

Here, we designed and synthesized a plant-derived ginger exosome-coated albumin nanoparticle drug delivery system (GEBSS) loaded with Shikonin (SHK) and STM2457 (a METTL3 inhibitor) and probes into the mechanism of antitumor. We prepared and characterized GEBSS nanoparticles and evaluated their in vitro cellular uptake and targeting capabilities. The in vitro antitumor efficacy was assessed by measuring cell viability, clonogenic formation, oxidative stress, mitochondrial function, and apoptosis markers; biosafety was confirmed via a hemolysis assay. Furthermore, the ability of GEBSS to induce ICD was validated through Western blotting, ATP detection, and immunofluorescence assays, while its role in epigenetic regulation was elucidated using Dot Blot, MeRIP-qPCR, and RNA stability experiments. Finally, the in vivo antitumor effect of GEBSS was verified by intravenous administration in a nude mouse subcutaneous tumor model. A subsequent characterization revealed that GEBSS exhibited a concentrated size distribution around 142\u00a0nm, were efficiently absorbed by colorectal cancer (CRC) cells, and demonstrated inhibitory effects on tumor cell proliferation. In vivo experiments demonstrated excellent tumor-targeting ability, anti-tumor efficacy, and biocompatibility of GEBSS. Mechanistically, GEBSS induced apoptosis and immunogenic cell death (ICD) in tumor cells. Moreover, at the epigenetic regulation level, GEBSS suppressed cell proliferation by reducing the m6A methylation levels of immune checkpoint genes PD-L1 and CD47. This study explored the feasibility of producing naturally derived nanocarriers and, for the first time, employed a combination of SHK and STM2457 for CRC treatment, offering novel strategies and insights for nanomedicine in CRC treatment.",

We examined the relationship between Y-box binding protein 1 (YBX1) and tumor-associated macrophages (TAMs) concerning LN metastasis in BCa. Popliteal lymphatic metastasis model was constructed in Balb/c mice. Histological examinations were conducted using hematoxylin and eosin (HE) and Immunohistochemical staining. Flow cytometry detected M1/M2 polarization markers. Immunofluorescence staining tested distribution of interleukin enhancer binding factor 3 (ILF3) and YBX1 and macrophage markers. Transwell and tube formation assays assessed migration and angiogenesis. Enzyme-linked immunosorbent assay (ELISA) measured C-X-C motif chemokine ligand 8 (CXCL8), transforming growth factor beta (TGF-\u03b2), vascular endothelial growth factor A (VEGFA) and macrophage markers. Levels of mRNA and protein were measured by RT-qPCR and Western blot. Subcellular localization of ILF3 and CXCL8 was detected utilizing fluorescence in situ hybridization (FISH) assay. Exosomes derived from BCa cells were isolated and identified. RNA immunoprecipitation (RIP) and Co-immunoprecipitation (Co-IP) validated molecular interactions. Knockdown of YBX1 in BCa cells suppressed lymphangiogenesis in vitro and in vivo and reduced M2 macrophage polarization. CXCL8 levels, elevated in BCa patients, were positively correlated with YBX1 and M2 macrophage infiltration, and this elevation was reduced upon YBX1 knockdown. BCa cell-derived exosomes containing YBX1 were internalized by macrophages, where they were crucial for inducing M2-like polarization and promoting CXCL8 expression, ultimately stimulating angiogenesis and lymphangiogenesis. Mechanistically, YBX1 interacted with ILF3 to stabilize CXCL8 mRNA. By inducing macrophage M2-like polarization, YBX1 promoted lymphangiogenesis and lymphatic metastasis in BCa, which may provide novel clinical markers for LN metastatic BCa.",

We aimed to define the cellular ecosystem of MIA and to clarify the role of periostin (POSTN) and POSTN+ CAF-derived exosomes in early LUAD progression. Single-cell RNA sequencing (scRNA-seq) and tissue-derived exosomal RNA sequencing were performed on four primary MIA lesions and matched adjacent lung tissues. Integrated analyses of scRNA-seq data, exosomal transcriptomes, the TCGA-LUAD cohort, and an independent LUAD tissue/serum cohort were used to characterize POSTN expression and to evaluate its prognostic and diagnostic relevance. Primary MIA-associated POSTN+ and POSTN- CAFs were isolated for exosome preparation, followed by co-culture experiments with LUAD cell lines and xenograft assays. scRNA-seq identified a malignant Cancer-alveolar type II (Cancer-AT2) epithelial subset and multiple CAF subsets. Among these, POSTN+ CAFs were enriched in MIA tissues and showed enhanced crosstalk with Cancer-AT2 cells through extracellular matrix (ECM)-related ligand-receptor interactions. Tissue-derived exosomes contained 588 differentially expressed mRNAs, among which POSTN was markedly upregulated and showed the strongest association with fibroblast-related signatures. POSTN was predominantly expressed in fibroblasts across independent non-small cell lung cancer datasets and was elevated in LUAD tissues, tissue-derived exosomes, and serum exosomes, correlating with advanced stage, lymph node metastasis, and poor survival. Functionally, POSTN+ CAF-derived exosomes promoted LUAD cell proliferation, migration, invasion, colony formation, and xenograft growth. Exosomal POSTN derived from POSTN+ CAFs may represent an important stromal mediator of MIA/LUAD progression and a potential diagnostic and prognostic biomarker in early-stage LUAD.",

Meningeal lymphatic vessels are crucial for A\u03b2 clearance, and their dysfunction accelerates AD progression. Vascular endothelial growth factor C (VEGF-C), through activation of vascular endothelial growth factor receptor 3 and downstream pathways, synergistically promotes lymphangiogenesis, enhances lymphatic permeability, and regulates lymphatic fluid flow, thereby improving A\u03b2 clearance efficiency. Genetic factors and aging-related declines in VEGF-C further impair meningeal lymphatic function, creating a vicious cycle. This review summarizes the mechanisms by which VEGF-C regulates the structure and function of meningeal lymphatic to promote A\u03b2 clearance, synthesizes the evidence that genetic factors and aging contribute to meningeal lymphatic dysfunction through their effects on VEGF-C, and discusses the prospects of individualized intervention strategies for Alzheimer's disease based on VEGF-C-mediated modulation of meningeal lymphatics, aiming to provide insights for AD prevention and treatment. \u963f\u5c14\u8328\u6d77\u9ed8\u75c5\uff08AD\uff09\u662f\u4e00\u79cd\u4ee5\u03b2\u6dc0\u7c89\u6837\u86cb\u767d\uff08A\u03b2\uff09\u6c89\u79ef\u4e3a\u6838\u5fc3\u75c5\u7406\u6539\u53d8\u7684\u795e\u7ecf\u9000\u884c\u6027\u75be\u75c5\u3002\u8111\u819c\u6dcb\u5df4\u7ba1\u662fA\u03b2\u6e05\u9664\u7684\u91cd\u8981\u901a\u8def\uff0c\u5176\u529f\u80fd\u969c\u788d\u52a0\u901fAD\u8fdb\u5c55\u3002\u8840\u7ba1\u5185\u76ae\u751f\u957f\u56e0\u5b50C\uff08VEGF-C\uff09\u901a\u8fc7\u6fc0\u6d3b\u8840\u7ba1\u5185\u76ae\u751f\u957f\u56e0\u5b50\u53d7\u4f533\u53ca\u4e0b\u6e38\u4fe1\u53f7\u901a\u8def\uff0c\u534f\u540c\u4fc3\u8fdb\u6dcb\u5df4\u7ba1\u65b0\u751f\u3001\u589e\u5f3a\u6dcb\u5df4\u7ba1\u901a\u900f\u6027\u53ca\u8c03\u8282\u6dcb\u5df4\u6db2\u6d41\u52a8\uff0c\u63d0\u9ad8A\u03b2\u6e05\u9664\u6548\u7387\u3002\u9057\u4f20\u56e0\u7d20\u548c\u8870\u8001\u76f8\u5173\u56e0\u7d20\u5bfc\u81f4VEGF-C\u8870\u51cf\u8fdb\u800c\u524a\u5f31\u8111\u819c\u6dcb\u5df4\u7ba1\u529f\u80fd\uff0c\u5f62\u6210\u6076\u6027\u5faa\u73af\u3002\u672c\u6587\u7efc\u8ff0\u4e86VEGF-C\u8c03\u63a7\u8111\u819c\u6dcb\u5df4\u7ba1\u7ed3\u6784\u548c\u529f\u80fd\u4fc3\u8fdbA\u03b2\u6e05\u9664\u7684\u4f5c\u7528\u673a\u5236\uff0c\u603b\u7ed3\u4e86\u9057\u4f20\u548c\u8870\u8001\u901a\u8fc7\u5f71\u54cdVEGF-C\u5bfc\u81f4\u8111\u819c\u6dcb\u5df4\u7ba1\u529f\u80fd\u969c\u788d\u7684\u8bc1\u636e\uff0c\u5e76\u5c55\u671b\u4e86\u57fa\u4e8eVEGF-C\u8c03\u63a7\u8111\u819c\u6dcb\u5df4\u7ba1\u7684AD\u4e2a\u4f53\u5316\u5e72\u9884\u7b56\u7565\uff0c\u4ee5\u671f\u4e3aAD\u9632\u6cbb\u7814\u7a76\u63d0\u4f9b\u53c2\u8003\u3002.",

Here, we report a multifunctional nanoplatform that integrates potent immune reprogramming with real-time immune monitoring to enable both precise immunomodulation and dynamic assessment. We engineer genetically modified cell-derived nanovesicles codisplaying anti-CD47 nanobodies and calreticulin (CRT) signals to simultaneously block the CD47-SIRP\u03b1 \"don't eat me\" axis and deliver potent \"eat me\" cues, thereby promoting tumor cell phagocytosis and dendritic cell (DC) maturation. These nanovesicles, cloaked in a pH-responsive tannic acid-manganese (TA-Mn) shell, achieve systemic stability while enabling tumor-selective ligand exposure and Mn2+-mediated activation of the cGAS-STING pathway, further amplifying innate immune signaling. This coordinated modulation drives DC activation, augments antigen cross-presentation, and reprograms tumor-associated macrophages toward an M1 phenotype, eliciting robust CD8+ T cell responses and durable immunological memory. To enable spatiotemporal tracking of immune dynamics, the platform integrates a nitric oxide-activatable photoacoustic probe for in situ visualization of macrophage repolarization during therapy. Across multiple murine tumor models, this strategy eradicates established tumors, prevents metastasis, and confers long-term immune protection. Together, this study introduces a versatile and adaptive immunotherapeutic paradigm that couples activatable theranostics with robust immune reprogramming, advancing a new frontier in precision cancer immunotherapy.",

In this study, we developed an injectable hydrogel (CTOHo) designed using honeysuckle-derived exosome-like nanovesicles (HoNVs) incorporated into a dynamic network created from carboxymethyl chitosan (CMCS), tannic acid (TA), and oxidised sodium alginate (OSA). HoNVs were isolated from fresh honeysuckle and characterised. The CTO-Ho hydrogel is synthesised through a dynamic network structure composed of CMCS, OSA and TA and loaded with HoNVs. Systematic characterisation and evaluation of the physicochemical properties of the CTO-Ho hydrogel were performed. The antibacterial activity against S. aureus, E. coli and MRSA; macrophage polarisation; ROS scavenging; HUVEC migration/tube formation; and full-thickness S. aureus-infected rat wounds were evaluated over 14\u00a0days. The resulting hydrogel was found to possess high gelation kinetics, good injectability with accurate adherence to the wound topography, and the pH-sensitive release of HoNVs under acidic conditions. Bioactive phytochemicals, such as flavonoids, phenolic acids, and alkaloids, are enriched in HoNVs. The synergistic interaction between HoNVs and TA endows CTO-Ho with strong biocompatibility, promotes angiogenesis, suppresses inflammation, exhibits antimicrobial activity, and scavenges reactive oxygen species, greatly increasing the regeneration of infected tissues. This plant exosome-functionalised carbohydrate-based hydrogel system offers a holistic and clinically viable approach for the targeted treatment of complex infected wounds.",

Accumulating evidence now implicates meningeal lymphatic dysfunction as a pivotal contributor to the pathogenesis of Alzheimer's disease (AD). This review critically evaluates current neuroimaging techniques for assessing meningeal lymphatic function in humans, highlighting their technical limitations in capturing dynamic pathological changes specific to AD. We summarize recent advances demonstrating that meningeal lymphatic impairment exacerbates key AD hallmarks-including amyloid-\u03b2 (A\u03b2) and tau deposition, neuroimmune dysregulation, and myelin degradation-collectively accelerating disease progression. Building on these insights, we systematically analyse emerging therapeutic strategies aimed at enhancing meningeal lymphatic function, such as pharmacological approaches (e.g., vascular endothelial growth factor C (VEGF-C)-mediated lymphangiogenesis), physical interventions (e.g., transcranial photobiomodulation), and surgical techniques (e.g., cervical lymphaticovenous anastomosis). However, significant challenges remain, including the scarcity of direct human evidence linking meningeal lymphatic dysfunction to AD and the lack of standardized, noninvasive assessment tools. To address these gaps, we propose future fundamental and clinical research directions for meningeal lymphatic vessels and AD. By bridging mechanistic insights with translational applications, this review highlights the role of the meningeal lymphatic system as a promising yet underexplored target for AD modification.",

The development of targeted and biocompatible drug delivery systems is urgently needed to control pulmonary inflammatory cascades while minimizing systemic toxicity. Plant-derived extracellular vesicles offer a naturally safe and anti-inflammatory platform for therapeutic delivery. Ginsenoside Rb1 (GRb1), a major bioactive compound from ginseng, possesses potent anti-inflammatory and anti-apoptotic properties, whereas lemon-derived EVs (LEVs) exhibit intrinsic antioxidant and anti-inflammatory effects. Here, we engineered a multifunctional, biocompatible drug delivery platform, GRb1@LEVs-cRGD, in which ginsenoside Rb1 is incorporated into and fused with LEVs to form hybrid bio-nanovesicles, while the vesicle surface is functionalized with cyclic RGD (cRGD) peptides to target integrin \u03b1v\u03b23 highly expressed in inflamed pulmonary tissues, thereby enhancing site-specific delivery. In vitro and in vivo studies confirmed that GRb1@LEVs-cRGD effectively inhibited M1 macrophage polarization, suppressed inflammatory cascades, and preserved epithelial-endothelial integrity. Furthermore, exogenous cholesterol loading improved vesicle stability, maintained the pH gradient, and enhanced the loading efficiency of tigecycline and vancomycin by six-fold. In murine models of bacterial pneumonia induced by carbapenem-resistant Klebsiella pneumoniae and methicillin-resistant Staphylococcus aureus, antibiotic-loaded GRb1@LEVs-cRGD efficiently accumulated at infection sites and exhibited synergistic anti-inflammatory and bactericidal effects. Overall, this study demonstrates that GRb1@LEVs-cRGD is a safe, targeted, and multifunctional therapeutic platform with significant potential for ALI/ARDS treatment.",

BC-derived exosomes influence intercellular communication within the tumor microenvironment, driving metastatic progression. However, the precise mechanisms by which exosomes facilitate LN metastasis in BC remain unclear. We performed small RNA sequencing on serum exosomes to identify Piwi-interacting RNAs (piRNAs) associated with BC LN metastasis. Functional investigations of exosomal piR-hsa-28212 included in\u00a0vitro assays for migration and tube formation of human lymphatic endothelial cells (HLECs), alongside an in\u00a0vivo footpad-popliteal LN metastasis model. Specific interactions between piR-hsa-28212 and TBX1 (T-box transcription factor 1), as well as TBX1 and VEGF receptor 3 (VEGFR3), were validated through luciferase reporter assays. The stability of TBX1 mRNA was analyzed by actinomycin D assay. RNA pulldown, RNA immunoprecipitation (RIP), and RNA fluorescence in\u00a0situ hybridization (FISH) assays were conducted to explore the interaction between piR-hsa-28212 and METTL3. PiR-hsa-28212 was significantly upregulated in serum exosomes of BC patients with LN metastasis. Exosomal piR-hsa-28212 enhanced HLECs migration and tube formation in\u00a0vitro and promoted lymphangiogenesis and LN metastasis in\u00a0vivo. Mechanistically, exosomal piR-hsa-28212 transferred from BC cells to HLECs stabilized TBX1 mRNA, thereby upregulating VEGFR3 expression. In BC cells, piR-hsa-28212 directly bound to and stabilized METTL3 protein, modulating N6-methyladenosine (m6A) methylation of vascular endothelial growth factor C (VEGFC) mRNA and consequently increasing VEGFC expression and secretion.

They play a key role in intercellular communication by transferring proteins, lipids, and nucleic acids. In cancer, EVs contribute to remodelling the tumor microenvironment, enhancing angiogenesis, modulating immune responses, promoting metastasis, and driving therapeutic resistance. This narrative review aims to highlight the biological importance and clinical relevance of EVs in cancer, focusing on their potential as biomarkers and therapeutic tools. A comprehensive literature search was conducted using PubMed, Scopus, and Web of Science. Studies on EV composition, isolation, and characterization methods, as well as recent advances in EV bioengineering, were critically examined to summarize their significance in oncology. Findings reveal that the molecular cargo of EVs reflects the physiological and pathological states of their source cells, supporting their role as non-invasive biomarkers for cancer detection and monitoring. EVs also regulate signaling pathways that sustain tumor heterogeneity and adaptability. Moreover, engineered EVs demonstrate strong potential as delivery systems for chemotherapeutic agents, RNA-based drugs, and immunomodulators, underscoring their translational value in targeted therapy.

This study integrated and analyzed transcriptomic datasets (GSE50161, GSE35493) from the Gene Expression Omnibus (GEO), focusing on the intersection between exosome-related genes (ERGs) and disease-associated differentially expressed genes (DEGs). Key biomarkers, FGF9, TGFBR1, and PLCB4, were identified using a machine learning model. The results demonstrated that TGFBR1 expression was up-regulated in the tumor microenvironment, whereas FGF9 and PLCB4 were down-regulated. These genes were closely associated with the \u03b3/\u03b1 (IFN-\u03b3/\u03b1) signaling pathway and E2F target activation. Immune profiling revealed that low expression of FGF9 and PLCB4 correlated with a reduction in central memory CD4+T cells, while high TGFBR1 expression was associated with an increase in memory B cells. Further regulatory network analysis uncovered potential epigenetic regulatory mechanisms. In silico drug screening and molecular docking suggested that the histone deacetylase inhibitor Trichostatin A may hold therapeutic potential.

In this study, a microfluidic chip platform integrating \"dynamic dilution-precise capture-mechanical stimulation-in situ analysis\" was constructed. Through the design of bionic narrow channels, efficient separation of exosomes and functional research at the single-cell level were achieved. On the one hand, the mechanical microenvironment within the chip was utilized to regulate the secretion of tumor cell exosomes (increasing secretion levels by more than twofold) and the expression of key proteins, revealing the exosome-mediated cell invasion behavior. On the other hand, using breast cancer as a model, the malignant transformation effects of exosomes derived from highly metastatic MDA-MB-231\u202fcells and low-metastatic MCF-7\u202fcells on normal MCF-10A breast epithelial cells were comparatively analyzed. The transformation efficiency was preliminarily verified using the CD43 (a marker associated with malignant transformation), and the reasonable inference was established regarding the regulatory role of PD-L1 in the epithelial-mesenchymal transition (EMT) process. Experiments were then conducted on whole blood samples (processing time for 0.5\u202fmL whole blood <10\u202fmin).

In this study, we systematically evaluated the anti-tumor effect of Bi2536, an inhibitor of Polo-like kinase 1 (PLK1), in HGSOC, and clarified its mechanism. Bi2536 inactivates PLK1, leading to the subsequent inactivation of cyclin-dependent kinase 1 (CDK1). This disruption triggers a cascade of antitumor effects, including G2/M phase arrest, induction of mitochondrial apoptosis, and suppression of cell migration and invasion. Furthermore, we identified circadian oscillations in PLK1 expression both in HGSOC cells and in vivo xenograft models. To enhance therapeutic precision and minimize systemic toxicity, we engineered a biomimetic nano-delivery system for Bi2536. This integrated platform combines chemotherapy and chemodynamic therapy (CDT), significantly improving antitumor outcomes. Importantly, synchronizing Bi2536 administration with the circadian peaks of PLK1 expression further augmented its therapeutic efficacy. In summary, our work establishes that the combination of Bi2536 with a biomimetic nano-delivery system, together with its chronotherapeutic administration, constitutes a highly promising and multifaceted strategy for the treatment of HGSOC.",

Exosomes (Exos) are key mediators of intercellular communication and promising vehicles for targeted therapy. This study aimed to investigate the function and underlying mechanism of exercise-derived exosomes (Exe-Exos) in SCI recovery. Circulating Exos were isolated from rats subjected to a 4-week treadmill Exe regimen and from sedentary controls. A gelatin methacrylate (GelMA) hydrogel microneedles (Hyd MNs) system was developed for the targeted, sustained delivery of these Exos directly to the injury epicenter at the T10 spinal segment in a rat SCI model. Using integrated in vitro and in vivo approaches, we showed that Exe-Exos significantly promoted motor function recovery, attenuated tissue damage, reduced apoptosis, and alleviated both inflammation and oxidative stress (Oxs) after SCI. Small RNA sequencing revealed that miR-151-3p is a key functional cargo that is enriched in Exe-Exos. Gain- and loss-of-function studies revealed that exosomal miR-151-3p exerts its protective effects by directly targeting the mitochondrial membrane protein ROMO1. This targeting led to the coordinated inhibition of the pro-apoptotic JNK/Caspase pathway, suppression of the NF-\u03baB-mediated inflammatory cascade, and activation of the Nrf2/HO-1 antioxidant axis. Collectively, our findings establish Exe-Exos, specifically exosomal miR-151-3p, as an exercise-responsive circulating signaling axis that orchestrates multifaceted protection against secondary injury after SCI, offering an innovative, mechanism-based strategy for neuroregenerative therapy.",

Moreover, the therapeutic efficacy of exosomes can be substantially enhanced through functional modifications and the incorporation of bioactive molecules. In this study, the MSCs were cultured under two-dimensional (2D) and three-dimensional (3D) cell culture conditions. The culture supernatants were collected for isolating exosomes. The characteristics and yields of exosomes from 2D and 3D cultures were detected by nanoparticle tracking analysis (NTA), transmission electron microscopy (TEM), western blot analysis, and bicinchoninic acid (BCA) assay. Subsequently, 3D exosomes were loaded with miR-99b-5p and modified with iRGD peptide were formed into a new engineered exosome, designated as iRGD-Exo-miR-99b-5p. The effects of these engineered exosomes on the progression of colorectal cancer (CRC) were assessed through a series of in vivo and in vitro experiments. The 3D-cultured MSCs exhibited a higher yield of exosomes and enhanced uptake by CRC cells. Further in vitro experiments demonstrated that 3D-exosomes loaded with miR-99b-5p effectively inhibit the proliferation, invasion, migration and epithelial-mesenchymal transition (EMT) of CRC cells. Results from a xenograft tumor model indicate that iRGD-modified exosomes were significantly enriched at tumor sites. Furthermore, exosomes modified with iRGD and loaded with miR-99b-5p were employed for CRC treatment, resulting in substantial tumor growth inhibition and enhanced the chemotherapy efficacy of 5-fluorouracil (5-FU) in vivo, without inducing notable toxicity or side effects. Mechanistically, exosome-mediated delivery of miR-99b-5p downregulated FGFR3 expression, thereby inhibiting the activation of the PI3K/AKt signaling pathway and promoting ferroptosis, ultimately attenuating CRC progression. Collectively, iRGD-modified 3D exosomes loaded with miR-99b-5p were able to specifically target tumor sites, thereby significantly suppressing CRC growth through the induction of ferroptosis via regulating the FGFR3/PI3K/AKt signaling pathway. These findings suggest that functional engineering and bioactive loading of 3D-exosomes derived from MSCs represent a promising strategy for targeted cancer therapy.",

While metabolites within the metastatic niche are increasingly recognized as determinants of organotropic metastasis, the role of exosome-mediated metabolite transfer in tumor-lymphatic endothelial cell (LEC) crosstalk remains largely unexplored. Here, we demonstrate that oleic acid (OA) is significantly enriched in both CC lymph node metastases and the peritumoral lymphatic microenvironment. Exosomes derived from highly metastatic CC cells actively package OA in a manner dependent on stearoyl-CoA desaturase (SCD), the rate-limiting enzyme of de novo fatty acid synthesis. Upon internalization by LECs, exosomal OA triggers the AKT/mTOR signaling axis, eliciting robust LEC proliferation and endothelial-to-mesenchymal transition (EndMT), thereby fostering lymphangiogenesis and nodal colonization. Knockdown of SCD abolishes these pro-lymphangiogenic effects, a deficit fully reversed by the reconstitution of OA-loaded exosomes. In vivo, exosomes from SCD-silenced cells exhibit a severely compromised capacity to drive primary tumor growth, intratumoral lymphangiogenesis, and lymph node metastasis (LNM). Notably, free OA administration exerts substantially weaker effects than its exosomal counterpart, underscoring the superior efficiency of exosome-mediated metabolite trafficking. Clinically, FASN and SCD expression are significantly upregulated in lymph node-positive specimens and positively correlate with lymphatic vessel density and p-AKT levels. Furthermore, circulating exosomal OA levels are significantly elevated in patients with nodal involvement, suggesting its potential as a non-invasive diagnostic biomarker. Collectively, our findings establish a paradigm wherein tumor-derived exosomes function as specialized vehicles for intercellular OA transfer, activating the AKT/mTOR pathway to license lymphangiogenic reprogramming. This work identifies exosomal metabolite shuttling as a central node in tumor-lymphatic communication and proposes targeting OA synthesis or exosomal delivery as a promising therapeutic strategy against CC metastasis.",

While current treatments either inhibit bone resorption or stimulate bone formation, their long-term use is associated with adverse effects, necessitating alternative therapeutic approaches. In this study, we explore the use of red ginseng-derived nanovesicles (RGNVs) as a biocompatible nanotherapeutic strategy for treating osteoporosis. The RGNVs were successfully isolated and characterized, revealing a lipid bilayer structure enriched in bioactive ginsenosides and functional proteins. In vitro, RGNVs enhanced osteoblast proliferation, differentiation, and mineralization while suppressing osteoclast differentiation and bone resorption by modulating the BMP-2/Smad and MAPK signaling pathways. In an ovariectomy-induced osteoporosis mouse model, oral administration of RGNVs significantly restored bone volume and mineral density, and biodistribution studies confirmed their preferential accumulation in the bone tissue. Systemic toxicity evaluation indicated no adverse effects, supporting the safety of RGNVs for therapeutic use. These findings suggest that RGNVs regulate bone remodeling through a dual mechanism, to stimulate bone formation and inhibit bone resorption, thereby offering a promising and well-tolerated approach for osteoporosis management.",

This recalcitrance stems largely from loss-of-function mutations within the low-density lipoprotein receptor (LDLR) gene, which severely undermine the efficacy of standard therapeutic regimens. Here, we report a bioinspired \"targeting and blockade\" strategy for the efficient delivery of functional Ldlr mRNA to hepatocytes. This approach is realized through a rationally designed platform, Szd\u00a0+\u00a0AP@ExoE-Ldlr, which integrates APOA1-functionalized exosomes for hepatocyte-targeted delivery with a preemptive macrophage blockade using the clinical ultrasound contrast agent Sonazoid (Szd). The APOA1 modification confers specific recognition by the scavenger receptor class B type 1 on hepatocytes, while the pre-saturation of Kupffer cells with Szd significantly mitigates nonspecific clearance by the mononuclear phagocyte system (MPS). In a HoFH murine model, this synergistic strategy markedly enhanced the accumulation of exosomes in hepatocytes and achieved robust restoration of hepatic LDLR expression. Consequently, it elicited a profound correction of the atherogenic lipid profile and substantially attenuated the progression of atherosclerosis. A comprehensive biosafety evaluation confirmed the excellent biocompatibility of this platform. Our work provides a promising and broadly applicable solution for the treatment of liver-related genetic disorders by simultaneously overcoming the critical barriers of targeted delivery and MPS evasion.",

Traditional vaccine platforms, such as live-attenuated or inactivated pathogens, although immunogenic, often present safety concerns. Conversely, subunit vaccines, despite being safer, generally exhibit poor immunogenicity due to inadequate delivery of antigens to professional antigen-presenting cells (APCs). To address this issue, the development of innovative delivery systems has become a pivotal strategy to overcome significant biological barriers, including extracellular antigen degradation, suboptimal lymph node targeting, and inefficient cross-presentation necessary for CD8+ T cell activation. This review systematically explores recent advancements in delivery technologies aimed at enhancing antigen presentation, encompassing rationally engineered nanocarriers and sophisticated biomimetic platforms. We first examine how nanoparticle properties like size, surface charge, and ligand density affect intracellular trafficking and the transition from MHC-II to MHC-I cross-presentation. Then, we explore bioinspired systems such as extracellular vesicles, virus-like particles, and cell-membrane-coated nanoparticles that utilize natural biological traits for enhanced targeting and immune modulation. Additionally, we review new physical delivery methods like microneedle arrays and in situ electroporation for direct, minimally invasive antigen delivery to dendritic cells. Lastly, we discuss the potential of these platforms in personalized cancer vaccines and combination immunotherapies. By combining insights from materials science, immunology, and bioengineering, these next-generation delivery tools could enhance antigen presentation and transform precision vaccination and immune intervention.",

Neutrophil activation is a central driver of RA pathogenesis; however, approaches that curb pathogenic neutrophil activity while preserving host defense are lacking. In patients with RA, we identified spleen tyrosine kinase (SYK) as a key upstream regulator whose aberrant activation drives neutrophil hyperactivation, neutrophil extracellular trap (NET) formation, inflammatory mediator release, and delayed apoptosis, while preserving antimicrobial function. Moreover, we engineered a HSA-AAPV-TKI (HAT) nanodrug by conjugating human serum albumin (HSA) to a SYK-targeted tyrosine kinase inhibitor (TKI) via a neutrophil elastase-cleavable AAPV peptide linker (Ala-Ala-Pro-Val). HAT is preferentially internalized by circulating neutrophils in CIA mice, traffics with them to inflamed joints, and releases the inhibitor in response to local neutrophil activation, thereby attenuating SYK signaling and pathogenic neutrophil functions while largely preserving antimicrobial activity. In a collagen-induced arthritis mouse model, HAT significantly reduced joint swelling, arthritis scores, and structural joint damage without impairing host defense. This strategy establishes a new RA therapeutic avenue that reconciles potent efficacy with immune safety and represents a milestone toward translational neutrophil-targeted therapy.",

Approximately 10-20% of gastric cancers overexpress HER2, conferring aggressive tumor characteristics and poor survival, yet resistance to trastuzumab-based targeted therapy and limited intratumoral antibody penetration continue to restrict clinical outcomes. This study evaluated HER2-targeted exosomes as a delivery platform. Exosomes were engineered to express the p51 peptide, a high-affinity HER2-binding ligand, and loaded with 17-dimethylaminoethylamino-17-demethoxygeldanamycin (17-DMAG), a potent HSP90 inhibitor. The cellular uptake and antitumor efficacy of p51-Exo17-DMAG were assessed in vitro using NCI-N87 and AGS cells and in vivo using a mouse xenograft model. p51-modified exosomes exhibited superior HER2 specific uptake. Treatment with p51-Exo17-DMAG significantly increased apoptosis, as demonstrated by elevated PARP and caspase3 cleavage, and downregulated oncogenic signaling molecules, including p-AKT, CDK2, VEGF, and c-Myc. Furthermore, p51-Exo17-DMAG increased the number of TUNEL-positive cells. In the NCI-N87 xenograft model, systemic administration of p51-Exo17-DMAG significantly inhibited tumor growth without toxicity or histological damage to major organs. Tumor analysis confirmed increased apoptosis and reduced proliferation in vivo. These findings demonstrate that p51-engineered exosomes provide an efficient, selective, and safe platform for HER2-targeted delivery of 17-DMAG, offering a promising precision medicine strategy for HER2-positive gastric cancer.",

The core mechanisms underlying these diseases include impaired T-cell and B-cell immune tolerance, abnormal cytokine production, and aberrant activation of related signaling pathways. Conventional treatments primarily focus on suppressing immune responses, but their efficacy remains limited and they are often associated with substantial side effects. Nanomedicine leverages nanoscale materials to enable precise diagnosis and targeted therapy. Nanocarriers can penetrate biological barriers, enhance cellular uptake, and prolong circulation time in vivo, demonstrating considerable potential for drug delivery. Common nanoscale drug delivery platforms include nanoparticles, polymeric micelles, liposomes, dendrimers, mesoporous materials, hydrogels, and exosomes. Each carrier type possesses distinct characteristics in terms of drug-loading capacity, stability, responsiveness, and biocompatibility, thereby enabling targeted delivery and controlled release. This review summarizes recent advances in nano-delivery technologies for three representative chronic autoimmune diseases: diabetes mellitus (DM), inflammatory bowel disease (IBD), and rheumatoid arthritis (RA). Nano-delivery systems can improve therapeutic outcomes by optimizing drug delivery, targeting complications, and modulating the pathological microenvironment. They enhance drug bioavailability, reduce off-target and systemic adverse effects, and provide novel strategies for the precise and efficient treatment of chronic autoimmune diseases.",

While mesenchymal stem cell-derived exosomes (MSC-Exos) hold potential for liver regeneration, their therapeutic efficacy is often limited by poor target specificity and rapid clearance. Here, we developed mannose receptor-targeting MSC-Exos (Man-Exos) by incorporating DSPE-PEG-Mannose via a post-insertion method to enhance LSEC-specific delivery. The physicochemical stability and targeting efficiency of Man-Exos were evaluated both in vitro and in vivo. Man-Exos exhibited high stability in various conditions and showed significantly enhanced binding affinity to LSECs compared to non-targeted exosomes. Notably, in a co-culture system of LSECs and macrophages, Man-Exos demonstrated superior selectivity for LSECs. In vivo biodistribution studies further confirmed that Man-Exos predominantly accumulated in the liver, specifically colocalizing with LSECs for up to 48\u2009h. Our findings suggest that Man-Exos can serve as a highly efficient and stable delivery platform for LSEC-targeted therapy, providing a promising strategy for enhancing the translational potential of exosome-based regenerative medicine in liver fibrosis.",

Given the high mortality of patients with esophageal squamous cell carcinoma (ESCC) and limited early detection tools, we investigated a salivary exosome\u2011based Tri-signature for its diagnostic and prognostic potential. The salivary exosome\u2011based signature (ie, a chimeric RNA seG-NchiRNA, a tRNA fragment GlyGCC-5, and a novel sRESE RNA) was quantified by qRT-PCR in a multicenter observational study across two ESCC-endemic regions. Model development and validation were performed in the training (n = 359) and validation (n = 225) cohorts using logistic regression, survival analyses, and Shapley Additive exPlanations-based feature interpretation. The Tri-signature showed excellent diagnostic accuracy (training cohort: AUC, 0.987; validation cohort: AUC, 0.964) and robust prognostic value (training cohort: overall survival [OS] hazard ratio [HR], 5.52, progression-free survival [PFS] HR, 4.46; validation cohort: OS HR, 4.76, PFS HR, 2.79). In the high Combined Risk Score for Prognosis (CRSP) subgroup, patients with relatively lower CRSP derived significant benefit from adjuvant therapy (training cohort: OS HR, 0.54, PFS HR, 0.47; validation cohort: OS HR, 0.38, PFS HR = 0.32), whereas no such benefit was observed in low Tri-signature patients. The Tri-signature exhibited strong early diagnostic performance, distinguishing early-stage ESCC without lymph node metastasis from healthy controls (training cohort: AUC = 0.975; validation cohort: AUC = 0.950). Patients with early-stage ESCC and high CRSP had significantly worse outcomes (training cohort: OS HR, 5.09, RFS HR, 3.80; validation cohort: OS HR, 8.79, RFS HR, 4.55). The salivary exosome-based tri-RNA signature showed robust multicenter reproducibility and strong diagnostic, prognostic, and treatment response-predictive performance, supporting its translational potential as a noninvasive biomarker panel for ESCC management.",

Their combined application may enhance early dermal repair following laser-induced skin injury. This study compares 3 commercially available plant derived extracellular vesicle formulations; Exoline, Glow, and Elysee, administered alone or with LLLT, in a rabbit ear wound model. Characterization of these preparations, including particle content and composition, was limited, and dosing was volume based. Two hundred forty adult male New Zealand White rabbits were randomly assigned to eight groups: untreated control, extracellular vesicle monotherapies, combination therapies with LLLT, and LLLT alone. Standardized full thickness laser-induced thermal skin defects (1\u2005\u00d7\u20051\u2009cm, 2\u2009mm depth) were created on the ventral ear surface. Extracellular vesicles were injected locally immediately after injury, and LLLT (650\u2009nm, 4.8 J/cm2, once weekly) was applied in addition to its application immediately after the procedure. Tissue samples were collected at baseline, day 7, and day 14. Collagen deposition and angiogenesis were quantified using Masson trichrome staining and CD31 immunohistochemistry, respectively. All extracellular vesicle treated groups showed significantly greater collagen deposition and microvascular density compared with controls. Combination therapy enhanced early regenerative responses compared with monotherapies. Differences among products may reflect formulation characteristics. Plant derived extracellular vesicle injections are associated with enhanced early dermal regeneration in laser-induced skin wounds, particularly when combined with LLLT.

Exosomes, nanoscale extracellular vesicles derived from mesenchymal stem cells and dermal papilla cells (DPCs), offer a promising regenerative alternative by modulating key hair-growth pathways. This systematic review evaluates the efficacy, mechanisms, and translational challenges of exosome-based therapies for hair restoration in AGA. A comprehensive search was conducted across Google Scholar, Embase, PubMed, Scopus, and Web of Science for studies published from 2019 to 2025. The search strategy prioritized AGA-related terminology, including androgenetic alopecia, male pattern hair loss, female pattern hair loss, baldness, exosomes, extracellular vesicles, and hair regrowth. Following duplicate removal, 39 studies meeting Population, Intervention, Comparison, Outcome, and Study design criteria were included for qualitative synthesis. Preclinical data demonstrate that exosomes promote hair regeneration through multiple synergistic mechanisms: activation of the Wnt/beta-catenin and Sonic Hedgehog pathways, suppression of transforming growth factor beta (TGF-beta)/SMAD3 signaling, delivery of anti-inflammatory cytokines (e.g., IL-10), and rejuvenation of senescent DPCs via microRNA cargo (e.g., miR-122-5p). Early clinical studies report improvements in hair density (8-20%) and shaft thickness; however, the evidence base remains limited by small sample sizes, retrospective designs, lack of control groups, and inconsistent outcome measures. Emerging delivery systems, such as thermoresponsive hydrogels and microneedle patches, show promise in enhancing follicular penetration but require further validation. Exosome therapy represents a multi-target regenerative approach for AGA with a favorable preliminary safety profile. However, widespread clinical adoption is hindered by critical gaps in manufacturing standardization, scalability, regulatory frameworks, and robust long-term efficacy data. Future research must prioritize large-scale randomized controlled trials with standardized endpoints and Good Manufacturing Practice (GMP)-compliant production protocols to validate these findings and establish exosomes as a mainstream therapeutic option for AGA.",

Mechanical forces due to lymph flow are required for proper lymphatic valve development, yet it remains unclear how lymphatic endothelial cells (LECs) sense and decode mechanical signals. In this study, we identify the cell guidance semaphorin receptor plexin D1 (PLXND1) as a lymphatic mechanosensor required for lymphatic valve morphogenesis. Conditional genetic ablation of Plxnd1 in LECs caused major defects in lymphatic valve development in 2 different lymphatic vascular beds. Mechanistically, PLXND1 acted as a mechanosensor within a lymphatic mechanocomplex, initiating distinct mechanical signals and activating the lymphatic valve transcriptional program through an unconventional pathway. Screening of patients with primary lymphedema identified PLXND1 missense variants, and functional analysis established 2 pathogenic variants that selectively disrupt the ligand versus mechanosensing functions of this receptor. Variants associated with lymphedema in members of the mechanocomplex disrupted its formation, underscoring the central role of this complex in lymphatic valve biology. Our work uncovers a mechanosensing mechanism guiding lymphatic valve development, and has profound implications for the understanding and treatment of primary lymphedema in humans.",

Immunotherapy has emerged as a promising treatment option for metastatic OSCC because of its potential clinical benefits; however, its effectiveness is limited by the immunosuppressive tumor microenvironment (TME), short-lived responses, and poor infiltration. To overcome these issues, we developed a strategy that combines photothermal therapy (PTT) with chimeric antigen receptor (CAR)-T cell immunotherapy. The prepared conjugated polymer nanoparticles (CPNPs) serve as efficient near-infrared-II (NIR-II) photothermal agents, enabling localized PTT and triggering strong immunogenic cell death (ICD) to activate T cells. Moreover, we engineered a lymph node-targeting nanosystem (ApoA1@PNPs) to improve in vivo production of CAR-T cells. Mucin 1 (MUC1)-specific CAR-T cells were designed to enhance tumor antigen recognition. This combined approach helps CAR-T cells reach primary tumor sites more effectively and induces long-lasting systemic immunity. By addressing the main limitations of traditional CAR-T therapy in OSCC, our integrated PTT/CAR-T strategy offers a potential therapeutic approach with significant clinical potential. This dual method aims to improve patient outcomes by achieving better tumor control.",

Here, we report a smart TEV/PVA-PEI-PPY@GG hydrogel that integrates tomato-derived extracellular vesicles (TEV), a polypyrrole (PPY)-based near-infrared (NIR)-responsive photothermal component, and a gellan gum (GG) matrix for diabetic wound treatment. The engineered platform exhibited favorable colloidal stability, a porous and structurally integrated architecture, tunable mild photothermal responsiveness under 808\u202fnm irradiation, and retained antioxidant activity associated with the vesicular fraction. In vivo, TEV/PVA-PEI-PPY@GG significantly accelerated wound closure, improved epidermal continuity, and enhanced dermal remodeling in streptozotocin-induced diabetic wounds, while showing no obvious histopathological toxicity in major organs. Immunohistochemical and histological analyses revealed altered expression patterns of AHR, TNF-\u03b1, CD31, and CD34 in treated tissues, which may contribute to tissue repair, modulation of inflammatory responses, and angiogenic remodeling during wound healing. These changes were associated with improved wound regeneration and restoration of tissue architecture. Overall, this work demonstrates the potential of a plant EV-integrated photothermally responsive hydrogel as a therapeutic strategy for diabetic wound repair and supports the possibility that local microenvironment modulation may contribute to its beneficial effects.",
"42395337": "ID: 42395337\nTitle: Intelligent responsive alloy scaffold temporally regulates the immune-osteogenic axis for the treatment of infectious bone defects.\nAbstract: Excessive immune activation induced by persistent bacterial infection, which further impairs osteogenic function, is a crucial factor contributing to the poor healing of infectious bone defects. Therapeutic strategies targeting a single link often yield limited efficacy. Therefore, we developed an alloy scaffold bone graft (TCMP) with pH-responsive sequential regulation of the immuno-osteogenic axis. During the infection phase, the scaffold mainly releases copper ions to exert potent antibacterial activity, and simultaneously releases Pueraria lobata-derived exosome-like nanovesicles (PELNs) in a pH-responsive manner, thereby effectively suppressing the early inflammatory cytokine storm. In the osteogenesis phase, the scaffold switches its release pattern to sustained magnesium ion release, accompanied by low-level sustained release of PELNs, which targets mesenchymal stem cells, vascular endothelial cells and macrophages to promote the directional recruitment and migration of stem cells, accelerate their osteogenic differentiation, improve the inflammatory immune microenvironment and enhance angiogenesis; consistent with the physiological characteristics of extremely scarce osteoclasts in the early stage of implantation, Mg2+ exerts no regulatory effect on osteoclasts in this study. Mechanistically, TCMP mediates dual-pathway synergistic therapy for infectious bone defects by inhibiting the advanced glycation end products/receptor for advanced glycation end products/nuclear factor-\u03baB (AGEs/RAGE/NF-\u03baB) pathway and activating the hypoxia-inducible factor-1 (HIF-1) signaling pathway. In conclusion, the developed TCMP alloy scaffold integrates the \"trinity\" functions of antibacterial activity, anti-inflammation, and osteogenesis, comprehensively breaking the vicious cycle of bacterial infection-excessive inflammatory activation-impaired osteogenic capacity, and providing a therapeutic strategy with excellent translational potential for clinical practice.",

Recent research highlights the pivotal role of small extracellular vesicles (sEVs) with specific cargo during the process. Herein, TLN1 was identified as being selectively enriched within sEVs from highly lymph-metastatic gastric cancer cells and in the serum of gastric cancer patients with lymph node metastasis, as identified through proteomic screening and confirmed by western blotting. sEVs act as key autocrine signals that influence gastric cancer cell behaviors such as proliferation, migration, invasion, and adhesion. TLN1 protein levels in cells correlate with their lymphatic metastatic potential and determine TLN1 content in sEVs. Inhibiting TLN1 reduces these cancer cell malignant behaviors and leads to TLN1-depleted sEVs. TLN1 could be transferred to gastric cancer cells and human lymphatic endothelial cells (HLECs) via sEVs. Without TLN1, sEVs cannot enhance cancer cell malignancy or induce HLEC proliferation, tube formation, adhesion, permeability in vitro, or lymphatic metastasis in vivo. Mechanistically, AKT activation was identified as a mediator of the effects exerted by sEV-TLN1 on both gastric cancer cells and HLECs. In conclusion, TLN1 orchestrates lymphatic metastasis in gastric cancer by dual-modulating tumor cell malignancy and lymphatic vessel remodeling via AKT activation. This discovery offers new perspectives on the mechanisms driving lymphatic metastasis in gastric cancer and proposes a promising target for the detection and therapeutic intervention of lymph node metastasis.",

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.",

These limitations can restrict their safety and immunogenic potential. Here, we developed a modular, peptide-based nanocomplex to overcome the current limitations. The system comprises three functional peptides: an RNA-binding peptide (RBP) for condensation, l-polyglutamic acid (PGA) for charge modulation, and an APC-targeting cell-penetrating peptide (A-CPP). This A-CPP features a newly discovered 7-mer immune cell-binding motif identified in this study. We optimized the physicochemical properties by systematically fine-tuning the ratios of these peptide modules. The optimized nanocomplex formed stable particles under 200\u202fnm. Unlike LNPs, which showed significant liver accumulation, the peptide-nanocomplexes remained localized at the injection site and effectively drained to the lymph nodes. Furthermore, the peptide-nanocomplex retained mRNA expression for up to 7 days in vivo, whereas LNP-mediated expression diminished within 48\u202fh. In mice immunized with SARS-CoV-2 spike mRNA, this prolonged antigen exposure elicited robust neutralizing antibody titers comparable to LNPs. Notably, the peptide-nanocomplex induced significantly higher CD8+ T cell responses than LNPs. Moreover, the peptide-nanocomplex demonstrated an excellent safety profile in vivo with no toxicity observed even after daily injections for two weeks at doses up to 200 times higher. This study establishes a data-driven fine-tuning strategy for peptide-based mRNA delivery. The resulting peptide-nanocomplex offers a safer, lymph node-targeted, and longer-lasting efficacy alternative to lipid-based carriers for next-generation vaccines.",

It is the first organized immune-stromal site exposed to lymph-borne melanoma-derived extracellular vesicles (EVs), soluble mediators, proteins, lipids, and non-coding RNAs (ncRNAs) before and during metastatic seeding. Current evidence supports a model in which melanoma-derived EVs traffic through lymphatic vessels, enter draining nodes, interact with lymphatic endothelial cells, medullary macrophages, dendritic cells, and T cells, and remodel lymphovascular, stromal, and immune compartments. Key vesicle-associated mechanisms include NGFR/p75NTR-positive small extracellular vesicles (sEVs) that drive lymphangiogenesis and nodal metastasis, PD-L1-positive vesicles that suppress T-cell activation, CD36-linked pathways that reshape myeloid lipid metabolism, and uPAR-associated vesicles that promote endothelial and matrix remodeling. EV-associated miRNAs, lncRNAs, and circRNAs may further regulate fibroblast activation, macrophage behavior, MAPK/ERK signaling, PTEN-related stromal restraint, glycolysis, autophagy, and tumor-suppressive pathways. This review integrates clinical SLN biology, lymphatic vesicle trafficking, cargo-specific protein and ncRNA pathways, immune tolerance, stromal remodeling, multi-omic profiling, and therapeutic interception. Comparative evidence from cutaneous squamous cell carcinoma and Merkel cell carcinoma broadens the field, but direct evidence linking lymphatic EVs to SLN remodeling remains strongest in melanoma.",

In this study, a methacrylated gelatin (GelMA)-based microneedle system was developed for the efficient transdermal delivery of extracellular vesicles derived from Polygonatum kingianum (PkEVs) to prevent UVB-induced skin photoaging. The PkEVs exhibited a typical spherical morphology, with an average diameter of 168.2\u00a0\u00b1\u00a010.1\u00a0nm, and were successfully incorporated into a GelMA-based microneedle system (Pk@MN) for transdermal delivery. Pk@MN exhibited sufficient mechanical strength, with a breaking force of approximately 0.36\u00a0N per needle, and showed a rapid PkEV release profile, with approximately 90% of PkEVs released within 10\u00a0min. In vitro, Pk@MN effectively inhibited UVB-induced oxidative stress and cellular senescence in HaCaT cells, as indicated by reduced intracellular reactive oxygen species (ROS) levels and decreased senescence-associated \u03b2-galactosidase (SA-\u03b2-Gal) positive cells. Pk@MN also suppressed LPS-induced inflammatory responses in RAW264.7 cells. In vivo, pretreatment with Pk@MN markedly inhibited UVB-induced skin photoaging in mice, maintained skin elasticity by suppressing epidermal thickening, and promote dermal collagen deposition, with a 2.1-fold increase in collagen density compared with the Model group. Moreover, Pk@MN significantly suppressed the expression of the proinflammatory cytokine interleukin-6 (IL-6), approaching the level observed in the Control group. Transcriptome sequencing analysis further suggested that the protective effects of Pk@MN were associated with the regulation of pathways related to inflammation, oxidative stress, and tissue repair. This study highlights a GelMA-based microneedle platform for efficient transdermal delivery of plant-derived extracellular vesicles and provides a promising strategy for preventing UVB-induced skin photoaging.",

To address these critical challenges, we developed an innovative dual-targeted nanoplatform (Exo-SPIONs-SRF/CGA) that synergistically combines the natural tumour-homing capability of HCC-derived exosomes with the magnetic guidance of superparamagnetic iron oxide nanoparticles (SPIONs) for precision drug targeting. This nanoplatform co-encapsulates SRF and CGA to improve the therapeutic index by enhancing desired responses and minimizing undesired side effects. The exosome component provides inherent biological targeting to HCC cells. At the same time, the incorporated SPIONs enable external magnetic field-guided spatial control, collectively ensuring superior tumour accumulation compared to conventional delivery systems. Furthermore, the platform's tumour microenvironment-responsive release characteristics ensure localized drug activation, maximizing the therapeutic index through spatial and temporal control of drug availability. In vitro and in vivo evaluations demonstrated that this nanoplatform significantly enhances tumour suppression and drug retention while reducing systemic side effects compared to monotherapies or single-modality nanocarriers. The Exo-SPIONs-SRF/CGA platform represents a promising strategy in HCC treatment, addressing fundamental limitations of current therapies by simultaneously overcoming biological barriers to drug delivery, enhancing therapeutic efficacy through synergistic drug combinations, and minimizing collateral damage to healthy tissues, thereby advancing the frontier of precision oncology toward more effective and safer HCC management.",
"42448218": "ID: 42448218\nTitle: Targeting soluble PD-1 alleviates peritoneal fibrosis by modulating PD-L1 recycling and mesothelial-mesenchymal transition.\nAbstract: Peritoneal fibrosis (PF) is a major cause of technique failure in long-term peritoneal dialysis (PD) patients, driven by a chronic microinflammatory state. While T-cell activation is implicated, the role of soluble programmed death-1 (sPD-1), primarily derived from activated T cells, in PF pathogenesis remains elusive. We initially analyzed serum sPD-1 levels in PD patients and employed a mice PF model induced by high-glucose dialysate and lipopolysaccharide (LPS). The functional impact of sPD-1 on the progression of PF was assessed through the administration of a PD-L1 fusion protein, or engineered exosomes designed to adsorb sPD-1. Serum sPD-1 levels were significantly elevated in long-term PD patients and were positively correlated with dialysis duration and markers of fibrosis, but inversely correlating with peritoneal function. In mice, exogenous sPD-1 exacerbated PF, whereas blockade with a PD-L1 fusion protein or sPD-1-adsorbing engineered exosomes markedly attenuated fibrosis, reduced T-cell infiltration, and preserved peritoneal function. Mechanistically, sPD-1 bound to PD-L1 on PMCs, triggering clathrin-mediated endocytosis. This interaction diverted PD-L1 from the lysosomal degradation pathway towards the Rab11-positive recycling endosome pathway, resulting in sustained upregulation of surface PD-L1 expression. This aberrant PD-L1 recycling activated pro-fibrotic signaling, culminating in mesothelial-to-mesenchymal transition (MMT). sPD-1 is a pivotal mediator linking peritoneal microinflammation to fibrosis by modulating the endocytic fate of PD-L1 in mesothelial cells. Targeting sPD-1, particularly using engineered exosomes or a PD-L1 fusion protein, represents a promising therapeutic strategy for preventing and treating peritoneal fibrosis.",
"42454189": "ID: 42454189\nTitle: Research on exosomes in cancer multidrug resistance and clinical translation.\nAbstract: Multidrug resistance (MDR) is a major clinical challenge that limits the efficacy of multiple cancer treatment modalities, including chemotherapy, targeted therapy, immunotherapy, monoclonal antibody therapy, and antibody-drug conjugates. In recent years, exosomes (Exos), nanoscale vesicles involved in intercellular communication, have attracted increasing attention for their roles in the formation and spread of MDR. A growing body of evidence suggests that Exos mediate the transfer of resistance-related molecular signals among drug-resistant cancer cells, drug-sensitive cancer cells, and stromal cells, such as cancer-associated fibroblasts and tumor-associated macrophages, through the selective packaging of noncoding RNAs, functional proteins, and metabolic regulators. These molecular signals may induce the reprogramming of signaling pathways, metabolism, and epigenetic states in recipient cells, thereby promoting the acquisition of cancer stem cell-like properties and a drug-resistant phenotype. In turn, these changes may contribute to the establishment of a drug resistance-supporting tumor microenvironment. This review systematically summarizes the molecular mechanisms by which Exos contribute to multidrug resistance, with a particular focus on their roles in cargo sorting, microenvironmental crosstalk, and the functional reprogramming of recipient cells. It also discusses their potential for clinical translation in resistance monitoring and reversal therapy. In addition, this review further discusses the key challenges currently facing the field and provides perspectives on future research directions.",
"42458565": "ID: 42458565\nTitle: Epigenetic modulation of the JAK2-STAT3 signaling pathway in osteoporosis: non-coding RNA networks as therapeutic targets.\nAbstract: Osteoporosis, a prevalent metabolic bone disease affects over 200 million people worldwide and is associated with an elevated fracture risk, is characterized by an imbalance between bone resorption and formation. The JAK2-STAT3 signaling pathway serves as a critical regulator of bone remodeling, but its chronic activation contributes to pathological bone metabolism in osteoporosis. Understanding the precise regulation of this pathway is essential for developing novel therapies. Our review reveals that specific miRNAs directly target components of the JAK2-STAT3 pathway (e.g. JAK2, STAT3, SOCS) to fine-tune osteoblast and osteoclast activity. This regulatory network is further expanded by lncRNAs and circRNAs, which act as competitive endogenous RNAs (ceRNAs) or \"molecular sponges\" to sequester miRNAs, thereby indirectly modulating JAK2-STAT3 signaling. This multi-tiered ncRNA network influences key processes such as osteogenic differentiation, inflammatory response and mitochondrial redox homeostasis, ultimately determining bone metabolic balance. The ncRNA network represents a promising therapeutic target for bone-related and metabolic diseases, especially osteoporosis, through its precise control over the JAK2-STAT3 pathway. Targeting these ncRNAs, potentially via engineered exosomes or biomaterial-based delivery systems, offers a novel and different strategy for restoring bone homeostasis, paving the way for future precision medicine in bone metabolic diseases.",

To provide a structured, evidence-based narrative review of platelet-rich plasma (PRP), extracellular vesicles/exosomes, and emerging adjunctive therapies in the context of hair transplantation. A structured literature search was conducted in PubMed/MEDLINE, Scopus, and Google Scholar databases from database inception to February 2025. English-language studies evaluating regenerative therapies in hair loss and hair transplantation were included. Study selection followed predefined inclusion and exclusion criteria, and evidence was synthesized narratively, with emphasis on study design, sample size, quantitative results, and methodological limitations. PRP shows moderate to strong evidence in androgenetic alopecia; increases in hair density of approximately 10-30 hairs/cm2 have been reported in randomized trials, but evidence specific to transplantation is limited and heterogeneous. Exosome-based approaches show preclinical effects on dermal papillary cell proliferation and angiogenesis, but lack robust clinical validation and standardized characterization. Emerging adjuvant therapies, including low-level laser therapy, microneedling-assisted application, and photoactivated PRP, exhibit variable efficacy with limited transplantation-specific data. PRP represents the most evidence-supported adjuvant therapy in hair transplantation, while exosome-based and emerging regenerative approaches are under investigation. Standardization of protocols, quantitative outcome reporting, and transplantation-specific endpoints are necessary to improve clinical translation and quality of evidence.",
"42467831": "ID: 42467831\nTitle: Extracellular vesicles and epigenetic aging clocks in tissue aging: an exosome-focused conceptual framework with a focus on skin.\nAbstract: Tissue aging is a multifactorial process characterized by cellular senescence, disrupted intercellular communication, and epigenetic alterations, with skin providing a clinically accessible and biologically informative model system. Exosomes and other extracellular vesicles (EVs) are increasingly recognized as mediators of aging-related signaling, whereas DNA methylation-based aging clocks offer quantitative measures of biological age. In this narrative review, we examine the potential interplay between EV/exosome biology and epigenetic aging clocks across tissue-aging contexts, while using skin aging as a primary focus and illustrative model. We review evidence from studies of keratinocytes, dermal fibroblasts, mesenchymal stromal cells, and aging-associated EV cargo, distinguishing studies with direct DNA methylation age readouts from those reporting indirect epigenetic effects. Current evidence indicates that EVs/exosomes from aged or senescent cells may disseminate pro-aging and inflammatory signals, whereas vesicles from young or regenerative sources may support repair and tissue homeostasis. Nevertheless, direct evidence that EVs alter skin epigenetic clock measures remains scarce. In particular, direct experimental evidence demonstrating that aged-cell-derived EVs or exosomes alter DNA methylation clock readings in human keratinocytes or dermal fibroblasts is currently lacking. We propose that skin serves as a useful model for investigating how extracellular signaling interfaces with epigenetic aging dynamics. Therefore, the proposed exosomal-epigenetic clock feedback-loop framework should be interpreted as a hypothesis-generating conceptual model rather than as a validated mechanistic pathway.",

Current treatments remain inadequate, highlighting the need for novel, effective, and cell-free therapeutic strategies. Extracellular vesicle-enriched preparations derived from human endometrial mesenchymal stem cells (eMSC-EV-enriched preparations) may possess regenerative and anti-fibrotic potential, yet their roles in scar modulation and underlying mechanisms remain unclear. eMSCs were isolated from human endometrial biopsies and characterized via flow cytometry and differentiation assays. The eMSC-EV-enriched preparations were obtained from conditioned medium and verified by TEM, NTA, and Western blotting. Functional assays were conducted in NIH3T3 fibroblasts to assess proliferation, migration, and transwell invasion capacity. A full-thickness cutaneous wound model and a bleomycin-induced dermal fibrosis model were used in C57BL/6 mice to evaluate tissue repair and fibrosis attenuation. Histological and molecular analyses were performed to assess collagen deposition, fibrosis-associated markers, and related signaling pathways. The potential involvement of miR-125b-5p in Smad2-related signaling was explored. The eMSC-EV-enriched preparations displayed characteristic vesicular morphology and marker expression. Compared with BMMSC-EV-enriched preparations, eMSC-EV-enriched preparations more effectively reduced fibroblast proliferation and migration, with decreased transwell invasion capacity in vitro. In vivo, the eMSC-EV-enriched preparations enhanced wound closure, reduced collagen deposition, and were associated with improved collagen organization and an increased number of appendage-like structures. Expression of \u03b1-SMA and collagen I and III was reduced in tissues treated with the eMSC-EV-enriched preparations. Furthermore, the preparations were associated with increased miR-125b-5p levels and decreased Smad2/p-Smad2 expression, suggesting involvement of the miR-125b-5p/Smad2 axis. In the bleomycin model, the eMSC-EV-enriched preparations attenuated dermal thickening and collagen accumulation during fibrosis induction. Our findings indicate that eMSC-EV-enriched preparations improve repair quality and attenuate fibrosis development, potentially through modulation of fibroblast activity and involvement of the miR-125b-5p/Smad2 signaling pathway. These findings support further investigation of eMSC-EV-enriched preparations as a cell-free strategy for improving tissue remodeling in fibrotic skin conditions.",

Within tumor microenvironment (TME), cancer-associated fibroblasts (CAFs) influence tumor metabolism through metabolic crosstalk. However, role of CAF-derived factors in regulating glutamine metabolism in laryngeal squamous cell carcinoma (LSCC) remains unclear. Primary fibroblasts were isolated from LSCC tumors and adjacent tissues and classified as CAFs or normal fibroblasts (NFs). These were co\u2011cultured with LSCC cell lines to assess effects on proliferation, migration, invasion, stemness, and chemoresistance using assays such as CCK\u20118, EdU, sphere formation, Transwell migration/invasion, and real\u2011time RTCA assays. Exosomes were harvested from fibroblast-conditioned media, characterized by TEM, NTA, and Western blotting, and used to treat LSCC cells. Metabolic profiling included Seahorse measurements, TCA metabolites, ATP content, glutamine uptake ([3H]-glutamine assay), glutamine consumption, as well as glucose consumption and lactate production assays. Mechanistic studies involved manipulating gene expression via transfection, and detection of targets by qRT\u2011PCR, Western blotting, and histological staining. Interaction of SFRP2, ELAVL1, and GID8 was assessed via Co\u2011IP and RIP assays. SFRP2 was increased in LSCC and linked to advanced stage, lymph node metastasis, and poor survival. It was mainly produced by a unique group of CAFs with myofibroblastic traits. Exosomal SFRP2 from these CAFs promoted glutamine uptake, mitochondrial activity, and aggressive tumor behaviors. Mechanistically, SFRP2 stabilized GID8 mRNA via ELAVL1 and promoted \u03b2-catenin nuclear translocation, activating canonical Wnt signaling. A novel CAF-driven SFRP2-ELAVL1-GID8 pathway promotes metabolic reprogramming involving in LSCC progression.",

As nanoscale intercellular communication vesicles that carry AD-related pathological molecules, exosomes are promising biomarkers and therapeutic carriers for AD. In this study, we downloaded AD-related gene expression profiles and clinical data from the Gene Expression Omnibus (GEO) database (datasets GSE138260, GSE29378, GSE36980, and GSE5281). Through a series of bioinformatics analyses, clinical predictive model construction, pharmacological network analysis, and molecular docking simulations, we developed an exosomal gene-based predictive model for AD pathogenesis and identified potential pharmacological networks and molecular docking targets for AD treatment. AD-related gene expression and clinical data were retrieved from the GEO database. Bioinformatics analyses, clinical model construction, drug-gene network analysis, and molecular docking were subsequently performed to explore exosomal gene models for predicting AD pathogenesis, as well as potential pharmacological networks and molecular docking targets for AD therapy. A five-exosomal-gene predictive model was established, comprising CD44, CXCR4, TUBB, PSMA5, and PSMB3. Pharmacological network analysis of these five genes revealed their significant associations with chelidonine, 2-chloro-1,4-dinitrobenzene, oxazolone, phencyclidine, thioridazine, and etodolac. Further molecular docking simulations identified key binding targets, including R41, Y42, R78, Y79, C77, I88, C97, A98, I96, I72, L70, E67, G103, I91, and T102. Our comprehensive analyses successfully established a reliable exosomal gene-based model for predicting AD pathogenesis, and identified relevant pharmacological networks and core molecular docking targets, providing novel insights for AD diagnosis and targeted therapy.",

Nanocrystals, nanosuspensions, lipid vesicles, polymeric nanoparticles, nanogels, extracellular vesicles, and lipid nanoparticles have been integrated with coated, dissolving, hollow, and hydrogel-forming microneedles for local and systemic delivery. Here, integrated colloid-loaded microneedles refer to systems in which colloidal carriers are coated onto, incorporated into, infused through, or reservoir-coupled with microneedle platforms, whereas solid microneedle pretreatment followed by topical colloid application is discussed only as a microneedle-assisted comparator. For integrated colloid-loaded microneedles, performance is not determined solely by microneedle geometry, insertion efficiency, or drug loading, but rather by whether the carrier survives conversion into a microneedle product and remains functionally relevant after hydration and release in skin. Existing reviews mainly emphasize microneedle materials, fabrication strategies, therapeutic applications, or smart devices, whereas the colloidal determinants of performance remain less integrated. Unlike application-centered or platform-centered reviews, this review focuses on the state transitions and functional persistence of colloidal carriers across fabrication, storage, insertion, hydration, redispersion, and dermal biointerfacial transport. We therefore reframe these products as formulation-device-biointerface systems, with emphasis on carrier integrity, matrix compatibility, redispersion, and post-insertion fate as determinants of therapeutic performance. To support mechanism-based evaluation, we further propose a study-level evidence hierarchy and practical analytical/QbD framework for assessing intact carrier delivery, redispersibility, bioactivity, and translational quality attributes. Issues related to biologic stability, sterilization, storage, manufacturing scalability, regulatory complexity, and critical quality attributes are also discussed within a quality-by-design framework.",

For instance, MSC-EXO promotes skin healing post-laser therapy and improves outcomes in severe COVID-19. Selecting an optimal cellular source is critical for the therapeutic development of MSC-EXO. It has been suggested that GMP-produced MSC-exosomes have slightly different molecular content. This study therefore aimed to compare adipose tissue-derived MSC-EXO (ASC-EXO) from three healthy donors, isolated and characterized under GMP conditions. Exosomes were analyzed by nano-tracking analysis (NTA), cryo-electron microscopy, tetraspanin profiling, and multi-omics (proteomics, lipidomics, small RNA sequencing), as well as bioinformatics. Functional assays quantified anti-inflammatory effects in RAW264.7 macrophages and collagen production by human dermal fibroblasts (HDF). In vivo efficacy of ASC-EXOs was evaluated in a house dust mite antigen-induced atopic dermatitis mouse model through histopathological evaluation of ear thickness and differential cell counting. No significant batch differences were observed in ASC-EXO yield or characteristics. Omics analyses revealed minor variations in protein, lipid, and small RNA cargo among the three batches, but GO-term bioinformatics indicated highly similar functional profiles. IL-6 suppression in RAW264.7 cells and cell proliferation and collagen production by HDF were similar among the ASC-EXO batches. CD73 enzymatic activity was consistent among batches. In vivo, the ASC-EXOs reduced skin thickness and eosinophilia in an atopic dermatitis model, with similar effects among the batches. In summary, ASC-EXOs from all batches demonstrated comparable anti-inflammatory and collagen-modulating effects in vitro, and similar inhibition of atopic dermatitis signs in vivo. We suggest that biological efficacy combined with bioinformatics analysis should guide MSC-EXO therapeutic quality control assays. These findings support the development of ASC-EXOs for clinical applications.",

In recent years, nanotechnology has provided a new strategy for the treatment and diagnosis of IBD due to its advantages of precise delivery, controllable release and multifunctional integration. We searched the Web of Science Core Collection database for relevant literature about nanotechnology and IBD published from 2005 to 2024. We used SciExplorer, VOSviewer, and Citespace to analyze countries, institutions, authors, keywords, highly cited references, and co-cited references to discuss research hotspots and trends in this field. The research analysis included a total of 959 pieces of literature, with China and the USA leading in the number of papers published and academic influence. The Georgia State University had the most papers posted. Merlin Didier and Xiao Bo were the scholars who published the most. The research hotspots mainly focus on nanodrug delivery systems, targeted therapy and inflammation regulation, while exosomes, macrophage polarization, and intestinal microbiota regulation are becoming new research frontiers. In the future, intelligent responsive nanomaterials, multifunctional nanoplatforms, and personalized nanotechnology will become important development directions. A new avenue for the accurate diagnosis and treatment of IBD has been unlocked by nanotechnology, but its clinical translation needs to break through the bottlenecks of biocompatibility, large-scale preparation and interdisciplinary collaboration.

The hydrogel was synthesized using polyethylene glycol (PEG), 2-hydroxyethyl methacrylate (HEMA), acrylic acid (AA), with N,N'-methylene bisacrylamide (MBA) as a cross-linker and potassium persulfate (KPS) as an initiator. The hydrogel's structural integrity and formation were confirmed through Fourier-transform infrared spectroscopy (FTIR), scanning electron microscopy (SEM), differential scanning calorimetry (DSC), and swelling studies. It is noteworthy that the hydrogel exhibits a different pH-dependent swelling behaviour, which expands under alkaline conditions and maintains its compact structure under acidic conditions. The content of acrylic acid contributed to the high-water retention and the swelling profile indicated that the product was suitable for the specific release of the drug at the site. The in-vitro release of rabeprazole sodium at acidic pH is very low, thus protecting rabeprazole sodium from premature degradation in the stomach; however, controlled release of rabeprazole sodium was achieved at intestinal pH via a non-Fickian diffusion mechanism (Korsmeyer-Peppas n = 0.40-0.62, Higuchi R\u00b2 = 0.991-0.996) over 12 h. Moreover, in-vivo acute toxicity studies indicated that the hydrogel is highly biocompatible, suggesting it is safe for use in future therapeutic applications. Overall, the PEG (HEMA-co-AA) hydrogel represents a versatile vehicle for the controlled and local administration of acid-labile pharmaceuticals, thereby promoting increased therapeutic efficacy.",

This study aimed to elucidate the function and mechanism of MZT2A in the metastasis of LUAD. Analysis of clinical samples and public databases revealed that MZT2A is highly expressed in LUAD tissues and significantly associated with lymph node metastasis, advanced stage, and poor prognosis. In vitro functional assays revealed that MZT2A overexpression significantly enhanced the invasion, migration, and adhesion of LUAD cells and induced epithelial-mesenchymal transition (EMT). Mechanistically, via its MOZART2 domain, MZT2A interacts with the SRCR domain of galectin-3-binding protein (LGALS3BP), promoting the sorting of LGALS3BP into exosomes and its subsequent secretion. Secretory LGALS3BP acts as a ligand, binding to integrin beta-1 (ITGB1) on the cell membrane through its BTB domain, thereby activating the downstream TGF-\u03b2/smad2 signaling pathway to drive EMT and metastatic phenotypes. Molecular docking and mutation experiments confirmed these critical domain interactions. In vivo experiments also validated that MZT2A overexpression promoted pulmonary metastasis, while LGALS3BP knockdown reversed this effect. Collectively, this study elucidated a novel \"MZT2A-LGALS3BP-ITGB1-TGF-\u03b2/smad2\" signaling axis that drives LUAD metastasis, providing a potential novel target for prognosis assessment and targeted therapy in LUAD.",

Nevertheless, the mechanisms underlying intercellular communication and transformation among heterogeneous tumor cells remain inadequately understood. In this study, we indicate that Ephrin type-A receptor 2 (EphA2) is heterogeneously expressed in gastric cancer (GC) tumor cells, with those exhibiting elevated EphA2 (EphA2High) expression demonstrating enhanced migratory and invasive capabilities. EphA2High cells facilitate the transfer of EphA2 via exosomes, which subsequently localize on the membrane of EphA2Low cells, thereby activating the ERK signaling pathway in a ligand-independent manner. This process promotes the transformation of EphA2Low cells and contributes to the progression of GC. An investigation into the correlation between serum levels and tumor metastasis in patients with GC revealed that those with lymph node metastasis exhibited higher levels of serum exosomal EphA2. This study elucidates the process of dominant group formation within heterogeneous tumor cells and suggests the viability of exosomal EphA2 as a potential biomarker for further clinical investigation.",

During the past two decades, the field has expanded from ultrastructural organ-mapping to hypotheses concerning stem-cell niche regulation, extracellular-vesicle-mediated communication, fibrosis, inflammation, and cancer-associated stromal remodelling. This expansion, however, has also generated methodological heterogeneity, with frequent reliance on non-specific markers such as CD34, PDGFR\u03b1, vimentin, and c-kit, often without ultrastructural validation or functional perturbation. In this critical review, we reassess the evidential status of major claims in telocyte biology, distinguishing robustly demonstrated mechanisms from plausible but incompletely proven hypotheses. The strongest functional evidence remains the conditional ablation of Wnt secretion in intestinal Foxl1-/Gli1-expressing subepithelial telocytes, which demonstrates their necessity for stem-cell niche maintenance. By contrast, most evidence from cardiac, dermal, reproductive, and fibrotic tissues remains supplementation-based or correlative. We propose a unified Stromal Network Organiser framework, in which telocytes are interpreted as tissue-specific stromal network cells whose dysfunction may involve not only numerical loss, but also telopode fragmentation, contact uncoupling, paracrine alteration, stromal replacement, and failed niche signalling. To improve methodological clarity, we introduce a two-dimensional evaluation matrix that separates identification confidence from functional confidence. We argue that the next decade of telocyte research should prioritise loss-of-function experiments outside the intestine, independent replication of foundational single-laboratory concepts, and high-resolution multi-organ correlative ultrastructural atlases.",
"42511736": "ID: 42511736\nTitle: Urinary Extracellular Vesicle-Derived miRNAs as Regulators and Biomarkers in Diabetic Kidney Disease.\nAbstract: Diabetic kidney disease (DKD) remains one of the most severe microvascular complications of type 2 diabetes mellitus (T2DM) and a leading cause of chronic kidney disease (CKD) worldwide. Nevertheless, despite considerable progress in elucidating its molecular background, early diagnosis and accurate stratification of disease progression remain challenging when relying on conventional clinical biomarkers such as albuminuria and estimated glomerular filtration rate (eGFR). Growing evidence indicates that DKD is driven by interconnected pathogenic mechanisms, including chronic hyperglycemia, activation of the protein kinase C (PKC) signaling pathway, renin-angiotensin-aldosterone system (RAAS) dysregulation, oxidative stress, inflammatory cascades, and immune system activation involving Toll-like receptors (TLR) and the NLRP3 inflammasome. These processes collectively contribute to endothelial dysfunction, podocyte injury, extracellular matrix accumulation, and progressive renal fibrosis. Exosomes and their molecular cargo, particularly miRNAs, have emerged as promising regulators and non-invasive biomarkers reflecting ongoing renal injury. Urinary exosomal microRNAs (uEV-miRNAs) are of interest due to their stability in biological fluids and their direct origin from nephron segments, enabling real-time reflection of renal pathophysiology. Accumulating studies suggest that differentially expressed microRNAs (miRNAs), including miR-21-5p, miR-30a-5p, miR-192-5p, and miR-142-3p, are closely associated with key pathways in DN. However, their clinical translation remains limited by methodological heterogeneity, the lack of standardized isolation protocols, and insufficient validation in large longitudinal cohorts. This review navigates the current landscape of knowledge on the molecular mechanisms underlying DKD and examines the emerging role of uEV-miRNAs as diagnostic biomarkers. Altogether, uEV-miRNAs offer a promising avenue for improving early detection, risk stratification, and disease monitoring in DKD.",
"42512321": "ID: 42512321\nTitle: Routes of Cancer Dissemination: Distinguishing Lymphatic and Hematogenous Spread from Venous Entry to Systemic Arterial Distribution.\nAbstract: Background/Objectives: Cancer metastasis is responsible for most cancer-related deaths, yet the precise anatomical and physiological routes by which cancer cells disseminate remain incompletely defined. This review aims to present an integrated model of lymphatic and hematogenous dissemination that provides a unified framework for understanding metastatic progression. Methods: The published literature on lymphatic biology, microvascular physiology, tumor immunology, and cancer metastasis was critically reviewed and integrated to develop a comprehensive anatomical and physiological model of cancer dissemination. Results: The proposed model identifies lymphatic dissemination as the predominant metastatic route in many solid tumors. Cancer cells enter structurally permissive initial lymphatic capillaries and are transported to the sentinel lymph node (SLN), where interactions with the tumor microenvironment may eliminate disseminated cells, maintain dormancy, or facilitate immune escape and further dissemination. Cancer cells that survive within or escape beyond the SLN subsequently travel through collecting lymphatics and the thoracic or right lymphatic duct to enter the systemic venous circulation. Following cardiopulmonary transit, surviving cells may be redistributed through the systemic arterial circulation to distant organs. A secondary pathway involves direct hematogenous intravasation through post-capillary venules, where reduced shear stress, increased endothelial permeability, and permissive endothelial biology facilitate entry into the venous circulation. Thus, lymphatic and direct venular pathways ultimately converge in the venous circulation before systemic arterial dissemination. Conclusions: This unified model integrates lymphatic and hematogenous dissemination into a coherent anatomical and physiological framework. By emphasizing the SLN as an early immunologic checkpoint and the arterial circulation as the final distribution network for disseminated cancer cells, this review provides a conceptual basis for understanding metastatic patterns and identifying biomarkers and therapeutic vulnerabilities.",
"42522609": "ID: 42522609\nTitle: [Research progress on extracellular vesicles in aortic aneurysms].\nAbstract: Aortic aneurysms, including thoracic aortic aneurysms (TAA) and abdominal aortic aneurysms (AAA), represent a group of severe vascular lesions with insidious onset and high mortality. Currently, effective diagnostic markers and pharmacological interventions remain lacking in clinical practice. Extracellular vesicles (EVs), as key mediators of intercellular communication, have attracted increasing attention in the research on aortic aneurysms due to their high content of bioactive molecules, favorable biocompatibility, low immunogenicity, and inherent targeting capacity. This review systematically elaborated on the research progress on EVs in TAA and AAA, highlighting their significant role in the development and progression of aortic aneurysms. EVs play a crucial role by mediating core pathological processes, including endothelial dysfunction, phenotypic transformation of vascular smooth muscle cells, inflammatory immune responses, and extracellular matrix remodeling. Additionally, this review discussed the potential of disease-specific molecules carried by EVs as novel liquid biopsy markers for the early diagnosis of aortic aneurysms. Furthermore, this review evaluated the application prospects of EVs as natural drug delivery platforms and EV-based therapeutic strategies for aortic aneurysm through engineering modifications (such as targeting peptide modification and biomaterial integration). In particular, \"cell-free\" immunomodulatory therapies, which enhance targeting capacity to lesion sites through engineering modifications and focus strategically on regulating the phenotype and function of key immune cells (such as macrophages), are increasingly emerging as a cutting-edge direction with the greatest translational potential in this field. Despite challenges such as targeted delivery, the integration of engineering technologies with nanomedicine holds promise for opening new avenues for the precise prevention and treatment of aortic aneurysms through EV-based integrated diagnostic and therapeutic strategies. \u4e3b\u52a8\u8109\u7624\u5305\u62ec\u80f8\u4e3b\u52a8\u8109\u7624(thoracic aortic aneurysm, TAA)\u548c\u8179\u4e3b\u52a8\u8109\u7624(abdominal aortic aneurysm, AAA)\uff0c\u662f\u4e00\u7c7b\u53d1\u75c5\u9690\u533f\u4e14\u81f4\u6b7b\u7387\u9ad8\u7684\u4e25\u91cd\u8840\u7ba1\u75c5\u53d8\uff0c\u76ee\u524d\u4e34\u5e8a\u4e0a\u5c1a\u7f3a\u4e4f\u6709\u6548\u7684\u8bca\u65ad\u6807\u5fd7\u7269\u53ca\u836f\u7269\u5e72\u9884\u624b\u6bb5\u3002\u7ec6\u80de\u5916\u56ca\u6ce1(extracellular vesicles, EVs)\u662f\u7ec6\u80de\u95f4\u901a\u8baf\u7684\u5173\u952e\u4ecb\u8d28\uff0c\u56e0\u5176\u643a\u5e26\u4e30\u5bcc\u7684\u751f\u7269\u6d3b\u6027\u5206\u5b50\u4e14\u5177\u5907\u826f\u597d\u7684\u751f\u7269\u76f8\u5bb9\u6027\u3001\u4f4e\u514d\u75ab\u539f\u6027\u548c\u5929\u7136\u9776\u5411\u6027\uff0c\u5728\u4e3b\u52a8\u8109\u7624\u76f8\u5173\u7814\u7a76\u4e2d\u65e5\u76ca\u53d7\u5230\u5173\u6ce8\u3002\u672c\u6587\u7cfb\u7edf\u9610\u8ff0\u4e86EVs\u5728TAA\u548cAAA\u4e2d\u7684\u7814\u7a76\u8fdb\u5c55\uff0c\u91cd\u70b9\u603b\u7ed3\u4e86EVs\u5728\u4e3b\u52a8\u8109\u7624\u53d1\u751f\u53d1\u5c55\u4e2d\u7684\u91cd\u8981\u4f5c\u7528\u3002EVs\u901a\u8fc7\u4ecb\u5bfc\u5185\u76ae\u529f\u80fd\u969c\u788d\u3001\u8840\u7ba1\u5e73\u6ed1\u808c\u7ec6\u80de\u8868\u578b\u8f6c\u6362\u3001\u708e\u75c7\u514d\u75ab\u53cd\u5e94\u53ca\u7ec6\u80de\u5916\u57fa\u8d28\u91cd\u5851\u7b49\u6838\u5fc3\u75c5\u7406\u8fc7\u7a0b\u53d1\u6325\u91cd\u8981\u4f5c\u7528\u3002\u540c\u65f6\uff0c\u672c\u6587\u63a2\u8ba8\u4e86EVs\u643a\u5e26\u7684\u75be\u75c5\u7279\u5f02\u6027\u5206\u5b50\u5728\u4e3b\u52a8\u8109\u7624\u65e9\u671f\u8bca\u65ad\u4e2d\u5c55\u73b0\u51fa\u4f5c\u4e3a\u65b0\u578b\u6db2\u4f53\u6d3b\u68c0\u6807\u5fd7\u7269\u7684\u6f5c\u529b\u3002\u6b64\u5916\uff0c\u8fd8\u8bc4\u4f30\u4e86EVs\u4f5c\u4e3a\u5929\u7136\u836f\u7269\u9012\u9001\u5e73\u53f0\u53ca\u57fa\u4e8e\u5de5\u7a0b\u5316\u4fee\u9970(\u5982\u9776\u5411\u80bd\u4fee\u9970\u3001\u751f\u7269\u6750\u6599\u7ed3\u5408)\u7684\u4e3b\u52a8\u8109\u7624\u6cbb\u7597\u7b56\u7565\u7684\u5e94\u7528\u524d\u666f\uff0c\u5c24\u5176\u662f\u901a\u8fc7\u5de5\u7a0b\u5316\u4fee\u9970\u589e\u5f3a\u5176\u5bf9\u75c5\u53d8\u90e8\u4f4d\u7684\u9776\u5411\u80fd\u529b\uff0c\u4ee5\u8c03\u63a7\u5173\u952e\u514d\u75ab\u7ec6\u80de(\u5982\u5de8\u566c\u7ec6\u80de)\u8868\u578b\u4e0e\u529f\u80fd\u4e3a\u7b56\u7565\u6838\u5fc3\u7684\u201c\u65e0\u7ec6\u80de\u201d\u514d\u75ab\u8c03\u8282\u7597\u6cd5\uff0c\u65e5\u76ca\u6210\u4e3a\u8be5\u9886\u57df\u6700\u5177\u8f6c\u5316\u6f5c\u529b\u7684\u524d\u6cbf\u65b9\u5411\u3002\u5c3d\u7ba1\u9762\u4e34\u9776\u5411\u9012\u9001\u7b49\u6311\u6218\uff0c\u4f46\u968f\u7740\u5de5\u7a0b\u5316\u6280\u672f\u4e0e\u7eb3\u7c73\u533b\u5b66\u7684\u878d\u5408\uff0c\u57fa\u4e8eEVs\u7684\u8bca\u7597\u4e00\u4f53\u5316\u7b56\u7565\u6709\u671b\u4e3a\u4e3b\u52a8\u8109\u7624\u7684\u7cbe\u51c6\u9632\u6cbb\u5f00\u8f9f\u65b0\u8def\u5f84\u3002.",
"42522799": "ID: 42522799\nTitle: Oral Squamous Cell Carcinoma: A New Era in Molecular Mechanisms and Emerging Targeted Therapies.\nAbstract: Oral squamous cell carcinoma (OSCC), the most common oral cancer, presents a clinical challenge due to its complex tumor microenvironment (TME), dysregulated pathways, and poor prognosis. Current methods of diagnosing OSCC use liquid biopsy technologies (ctDNA/microRNAs/exosomes) instead of relying solely on traditional methods such as open surgical biopsy. Liquid biopsy technologies provide non-invasive ways to detect and monitor OSCC in early stages, compared with traditional open surgical biopsy methods. Treatment of OSCC currently relies on chemotherapeutics (cisplatin/5-FU), radiotherapy, and targeted agents (cetuximab). However, resistance is acquired due to TME remodelling (tumor microenvironment) and/or due to epithelial-mesenchymal transition (EMT) through processes such as ABC transporter efflux. This review elucidates key molecular mechanisms, including PD-L1-mediated immune evasion, PI3K/AKT/mTOR hyperactivation, EGFR overexpression, and NF-\u03baB-driven inflammation, which promote proliferation, metastasis, and therapy resistance. One area of study involves the use of nanotechnology to convert phytocompounds (medicinal plants) into therapeutic agents by embedding phytocompounds into nanoparticles created using green synthesis techniques. EPR (Enhanced Permeability and Retention), ligand functionalization for OSCC targeting, improved bioavailability, and reduced toxicity are all advantages that the aforementioned systems provide, offering an opportunity to synergistically develop new therapies with chemotherapeutics for overcoming resistance. While numerous preclinical studies demonstrate that these newly developed therapies show increased efficacy compared with current therapy options, further work is needed in areas such as standardization, scaling, and clinical translation. As such, the importance of developing pathway-informed diagnostic tests and developing therapies that exploit pathway-specific activity with phytocompounds is emphasized. In addition, large-scale studies should be considered to evaluate the effectiveness of a pathway-informed approach in assessing and differentiating OSCC and personalized therapy strategies, to improve OSCC survival outcomes.",

To deliver drugs specifically to cancer cells that overexpress CD44, this study developed hyaluronic acid (HA)-functionalized dextran (DEX) polymeric nanoparticles (ETP-DEX-HA-NPs). Optimised nanoparticles (174.7\u2009\u00b1\u20093.2\u2009nm, -12.83\u2009\u00b1\u20091.1\u2009mV) demonstrated significant entrapment efficiency (62.75\u2009\u00b1\u20092.32%) and drug loading (55.64\u2009\u00b1\u20093.86%), with partial amorphization validated by FTIR, XRD, Raman, NMR and DSC analyses. The formulation exhibited prolonged, pH-responsive release, markedly improved solubility (p\u2009<\u20090.05), and greater cytotoxicity in HCT-116 cells (IC50: 6.83\u2009\u00b1\u20090.35\u2009\u00b5g/mL compared to 41.89\u2009\u00b1\u20091.02\u2009\u00b5g/mL for free ETP). It facilitated CD44-mediated uptake, enhanced apoptosis, induced G2/M arrest, elevated ROS production and inhibited migration while preserving biocompatibility. Network pharmacology and molecular docking identified key interactions with CRC-related targets (e.g. TOP2A, BCL2). ETP-DEX-HA-NPs offer a promising, targeted nanoplatform that addresses ETP's limitations, boosting therapeutic efficacy and safety for CRC treatment.",
"42526345": "ID: 42526345\nTitle: Exosome-mediated delivery of 3-n-butylphthalide rescues microglial energy crisis and ameliorates neuroinflammation in ischemic stroke.\nAbstract: Stroke remains the second leading cause of death and the primary cause of long-term disability worldwide, with ischemic stroke accounting for the majority of cases. Ischemia triggers robust microglial activation, yet the precise regulatory mechanisms underlying microglial functional reprogramming remain incompletely understood. Here, we demonstrate that excessive mitophagy drives metabolic energy failure in microglia following cerebral ischemia, resulting in impaired phagocytosis and exacerbated neuroinflammation. Analysis of single-cell RNA-sequencing data from mouse brains in the sham, transient middle cerebral artery occlusion (tMCAO, mMCAO), and permanent middle cerebral artery occlusion (pMCAO, sMCAO) groups revealed that mitophagy was markedly activated in microglia under sustained ischemia and was associated with impaired phagocytic and cytoskeletal pathways. In vitro oxygen-glucose deprivation (OGD) assays showed that phagocytosis of apoptotic neurons by microglia induced upregulation of Drp1, triggering excessive mitochondrial fission and mitophagy, which caused ATP depletion and reduced clearance capacity. The mitophagy inhibitor 3-methyladenine alleviated inflammatory responses but failed to restore mitochondrial quality. In contrast, 3-n-butylphthalide (NBP) stabilized mitochondrial membrane potential, restored ATP production, and improved microglial phagocytic defects and inflammation. To achieve targeted delivery, we constructed BV2 microglia-derived exosomes encapsulating NBP (BV2exo@ NBP), which efficiently enhanced drug accumulation in ischemic lesions and significantly improved neurological outcomes in stroked mice. These results identify excessive mitophagy as a core mechanism underlying microglial energy crisis after cerebral ischemia and provide a mitochondria-targeted therapeutic strategy for ischemic stroke. Importantly, the neuroprotective efficacy, mitochondrial restoration, and anti-inflammatory effects of BM@NEB were fully recapitulated in 18-month-old aged mice, a clinically relevant model that more closely reflects the stroke patient population, supporting the translational potential of this exosome-based therapeutic strategy.",

Cuproptosis has emerged as a promising mechanism by which to inhibit tumors because copper homeostasis disorders frequently occur in various malignancies. The combination of disulfiram (DSF) and copper ions (DSF/Cu) has been shown to have significant antitumor effects. This study utilized DSF/Cu to investigate the mechanism underlying cuproptosis in GC cells. GC cells were treated with DSF/Cu and protein sequencing was performed to screen for differentially expressed genes. The mechanism by which overexpressed FDX1 regulates cuproptosis and WDR43 expression was determined. Subsequently, how to improve the efficacy of DSF/Cu in the treatment of GC was studied in a mouse model of GC. DSF/Cu had a good therapeutic effect on promoting cuproptosis in GC cells. Protein sequencing revealed WDR43 as a downstream gene of FDX1. Increasing the expression of FDX1 enhanced the sensitivity of GC cells to copper treatment and inhibited the expression of WDR43, thereby exerting an antitumor effect. Furthermore, DSF/Cu was loaded into exosomes derived from natural killer (NK) cells to enhance the biological safety and tumor targeting of DSF/Cu and validate the inhibitory effect on GC both in vitro and in vivo. This study showed that DSF/Cu promoted cuproptosis and the expression of FDX1 affected cuproptosis sensitivity of GC. Moreover, the combination of NK cell exosomes with DSF/Cu improved the therapeutic effect of DSF/Cu, which helps to promote the targeted therapy of GC and improve clinical applicability.",

The liposomes maintain a negative surface charge under physiological conditions to prolong circulation, but undergo pH-responsive conversion to a positive charge within the acidic tumor microenvironment (pH 6.5-6.8), thereby improving tumor-selective internalization. The optimized formulation achieved targeted mitochondrial delivery, where IR780-induced reactive oxygen species (ROS) production and mild hyperthermia activated stress pathways, leading to mitochondrial disruption and ultimately initiating immunogenic cell death (ICD). Concurrently, encapsulated Erianin effectively suppressed photothermal therapy (PTT)/photodynamic therapy (PDT)-induced programmed cell death ligand 1 (PD-L1) upregulation. This nanoplatform not only avoids the drawbacks of conventional chemotherapy but also establishes a synergistic therapeutic framework integrating PTT, PDT, and chemotherapy. By counteracting resistance mechanisms and limiting immune checkpoint expression, the system provides robust antitumor activity and introduces an innovative approach for advancing liposomal strategies in combinatorial cancer therapy.",

Exosomes, as promising endogenous nanocarriers, have emerged as a powerful tool for the prevention and treatment of CVDs. In particular, advanced functionalization strategies have largely enhanced exosomal therapeutic efficacy in\u00a0vivo. Notably, Traditional Chinese Medicine (TCM) and its bioactive components exert profound regulatory effects on exosomes. In this review, we systematically summarize exosome-based therapeutic strategies for CVDs, along with state-of-art functionalization approaches to optimize exosomal cargo loading and targeted delivery. We further provide a comprehensive overview of TCM-mediated exosomal regulation. We found that TCM and TCM-derived chemicals can optimize exosomal cargo loading, especially the loading of microRNAs (miRNAs) and bioactive chemicals. More importantly, TCM and chemicals can promote exosomal secretion, which provides new avenues for exosomal-scale production. Besides, there are synergistic effects between exosomes and TCM when co-administered. Collectively, exosome-based systems hold great promise for CVD therapy, and TCM provides novel strategies for exosomal functionalization, which substantially enhances exosomal-mediated therapeutic efficacy for CVDs.",

In recent years, biomimetic membrane preparations, primarily biomimetic cell membrane preparations and exosomes, have emerged as a novel therapeutic strategy for myocardial ischemic injury. Owing to their natural bioactivity, easy engineerability, and other characteristics, they enable the targeted delivery of TCM components to ischemic lesions and facilitate their transport across biological barriers. This review focused on the core pathological mechanisms of myocardial ischemic injury, elaborated on the types and unique functions of biomimetic cell membrane preparations and exosomes, and provided a critical analysis of the design strategies and action mechanisms of such biomimetic cell membrane preparations. Furthermore, it discussed the adaptability of different administration routes and highlighted the potential and the existing challenges of natural biomimetic membrane preparations.

The secreted extracellular vesicles (EVs) of organoids, in particular the small-sized EV subset referred as exosomes (30-200\u00a0nm), have emerged as novel therapeutics in regenerative medicine. This study investigated the encapsulation and controlled release of human spinal cord organoid (hSCO)-derived EVs in viscoelastic hyaluronic acid (HA) hydrogels and assessed their impact on organoid patterning. A series of pH-responsive hydrogels were fabricated, leading to sustained EV release regulated by viscoelastic properties. The pH of these hydrogels decreased from 9 to 7 during incubation, which altered hydrogel viscoelasticity, thereby modulating EV release kinetics. In addition, EV-loaded hydrogels regulated key hSCO patterning markers such as DBX1 and ISL1. Furthermore, these EVs in hydrogels can cross a modeled blood-spinal cord barrier and provide cross-barrier capability for delivery. Taken together, the organoid-secreted EVs in viscoelastic HA hydrogels can be released at a controlled rate and have potential to regulate spinal cord organoid patterning. This study advances our knowledge of regulating intercellular communication and developing EV-based therapies for treating neurological disorders such as spinal cord injury.",
"42543715": "ID: 42543715\nTitle: The Role of dWAT-Immune Crosstalk in Hair Follicle Microenvironment in Hair Regeneration.\nAbstract: The hair follicle microenvironment is the core functional unit of hair regeneration. dWAT (Dermal white adipose tissue) is an indispensable component of this microenvironment. Rather than serving as a passive filler, dWAT, through multidimensional mechanisms including cytokines, metabolites, extracellular vesicles, and cell-cell interactions, forms a complex regulatory network with local immune cells and exerts unique immune functions. It is deeply involved in the maintenance of local immune homeostasis, the regulation of the inflammatory response, and hair regeneration. In this review, we summarize the latest research on the effect of adipose-immune interactions on hair growth within the hair follicle microenvironment, focusing on how the dWAT surrounding the hair follicle serves as the foundation of the local adipose-immune interaction microenvironment, and on the regulatory mechanisms by which the immune function of hair follicle dWAT influences hair follicle regeneration. The dynamic remodeling of dWAT along the hair follicle cycle provides key metabolic support for the formation and regulation of the immune microenvironment around the hair follicle, and also constitutes the material basis for the crosstalk among immune cells within the hair follicle. The interaction between dWAT and immune cells affects the hair follicle growth process by regulating the local inflammatory response, immune cell phenotypic switching, and associated signaling pathways.",

Despite advances in stem cell therapy, clinical translation remains hindered by donor variability and ethical constraints. This study evaluates the therapeutic potential of exosomes derived from induced pluripotent stem cell-derived mesenchymal stem cells (iPSCMSC-exo) versus umbilical cord-derived MSC exosomes (hUCMSC-exo) for POI intervention. In vitro, both exosome types enhanced migration and tube formation of human umbilical vein endothelial cells (HUVECs), while iPSCMSC-exo additionally promoted proliferation. iPSCMSC-exo attenuated cisplatin-induced granulosa cell apoptosis, while both types suppressed p21-mediated cell cycle arrest. In the cisplatin-induced POI mouse model, exosome treatment effectively restored Follicle-stimulating hormone (FSH) levels. However, the therapeutic efficacy of exosomes in restoring anti-M\u00fcllerian hormone (AMH) levels and follicle counts was limited, as confirmed by synchrotron radiation microtomography revealing persistent structural depletion. Notably, iPSCMSC-exo demonstrated functional outcomes similar to hUCMSC-exo. The autologous origin and scalable production of iPSCMSCs address donor heterogeneity and supply limitations inherent to traditional MSC sources. Further optimization of targeted delivery systems is warranted to overcome biodistribution challenges and enhance structural regeneration.",
"42547642": "ID: 42547642\nTitle: The Dual Roles of Microglia- and Astrocyte-Derived Exosomes in Cerebral Ischemia-Reperfusion Injury: from Intercellular Communication to Therapeutic Prospects.\nAbstract: Cerebral ischemia-reperfusion injury (CIRI) is a complex pathological process characterized by metabolic dysfunction, oxidative stress, neuroinflammation, and structural and functional alterations of the neurovascular unit (NVU). Across different studies, CIRI has been reported to be associated, to varying degrees, with neuronal injury and neurological dysfunction. Increasing evidence suggests that exosomes (EXOs) derived from glial cells, particularly microglia and astrocytes, play critical roles in mediating intercellular communication and regulating injury progression in CIRI. This review systematically summarizes the context-dependent and heterogeneous functions of glia-derived EXOs in CIRI. Microglia-derived EXOs exhibit diverse and context-dependent functions depending on the activation state of donor cells and the surrounding microenvironmental conditions. Under pro-inflammatory conditions, EXOs released from microglia may exacerbate inflammation by carrying cargo components such as circular RNAs (circRNAs) and pro-inflammatory proteins, whereas EXOs associated with reparative states may support tissue recovery through the delivery of functional non-coding RNAs. These cargo components may participate in pathological regulation through multiple signaling pathways. Among them, the nuclear receptor coactivator 4 (NCOA4) axis is associated with ferroptosis, ubiquitin-specific protease 14 (USP14) with proteostasis/apoptosis, and thioredoxin-interacting protein (TXNIP) with inflammasome activity, all of which have been linked to reduced neuronal injury and functional recovery. In addition, M2-type-derived EXOs may participate in the regulation of synaptic plasticity and axonal regeneration by modulating the plexin A2 (PLXNA2)/RhoA/ROCK2 signaling pathway. Astrocyte-derived EXOs (ATC-EXOs) further contribute to NVU regulation. A2-type-derived EXOs have been reported in multiple experimental models to be associated with reduced NLR family pyrin domain containing 3 (NLRP3) inflammasome activity and alterations in the PI3K/Akt and MAPK signaling pathways, accompanied by attenuated inflammatory responses and improved blood-brain barrier (BBB) integrity in these models. Some studies suggest that these effects may be related to the transition of microglial phenotypes toward reparative states; however, sufficient in vivo mechanistic evidence supporting their direct regulatory effects remains lacking. In contrast, neurotoxic astrocytes (A1)-derived EXOs exhibit limited or context-dependent effects. Importantly, exosome function is highly state-dependent and cannot be fully explained by simplified pro-inflammatory microglia anti-inflammatory microglia (M1/M2) or A1/A2 paradigms. Moreover, extracellular vesicle heterogeneity and methodological limitations remain major challenges. Despite promising therapeutic potential, including the ability to cross the BBB and enable multi-target regulation, significant barriers to clinical translation persist, such as delivery efficiency, biodistribution, and standardization. Overall, glia-derived EXOs represent a dynamic and multi-level regulatory system in CIRI and a promising platform for precision therapeutic strategies.",

However, these processes occur in a highly vascularized tissue, and the relationship between osteocytes and bone vasculature remains poorly understood. This review summarizes current knowledge on osteocyte-vascular interactions, with a focus on communication mechanisms and their relevance to bone physiology, aging, and disease. Emerging evidence indicates that osteocyte-vascular communication occurs through several modalities. Indirect signalling involves paracrine factors secreted by osteocytes, including VEGF, sclerostin, neuropeptide Y, as well as extracellular vesicles, which modulate ECs' behaviour. Direct communication has also been suggested through physical interactions between osteocytes and blood vessels, including mitochondrial transfer and potentially gap junctions. Recent studies have also identified lymphatic vessels within bone, raising the possibility of previously unrecognized interactions between osteocytes and the lymphatic vasculature. Together, these findings highlight diverse modes of communications and associated signalling pathways, through which osteocytes may regulate vascular function within bone. Despite emerging insights into osteocyte-bone vasculature crosstalk, the underlying mechanisms remain incompletely understood. Advances in experimental tools may improve our knowledge of this bidirectional dialogue, providing new perspectives on bone physiology, skeletal pathologies, and potential therapeutic strategies targeting this interaction.",

Probiotics and postbiotics represent promising preclinical candidates to alleviate these unmet clinical bottlenecks. Bacterial extracellular vesicles (BEVs) are naturally secreted bacterial nanovesicles carrying abundant bioactive cargos, whose bioactivity and safety are highly strain-dependent. Probiotics-derived BEVs can remodel gut homeostasis, repair epithelial barriers, and regulate mucosal immunity to suppress the inflammatory vicious cycle in IBD, while pathogen-/pathobiont-derived BEVs loaded with lipopolysaccharide and virulence factors exacerbate intestinal inflammation. Native BEVs are restricted by low cargo loading, poor gastrointestinal stability and inadequate colon tropism. Rational engineering strategies, including surface modification, self-loading hybridization, genetic manipulation, and pH-responsive coating, can optimize the therapeutic performance of BEVs. This review systematically summarizes BEVs biological mechanisms, engineering approaches, and translational obstacles and outlines prospects for the design of intelligent multifunctional BEVs and standardized large-scale manufacturing as future directions, providing theoretical support for oral BEVs nanotherapies against IBD.",

Herein, we developed a biomimetic manganese-amplified STING nanoagonist to potentiate PD-L1 blockade immunotherapy. Hollow mesoporous manganese silicate nanoparticles were engineered as Mn2\u207a-releasing nanocarriers for loading a STING agonist (Sa) diABZI, followed by coating with anti-PD-L1 antibody-functionalized NSCLC tumor cell membranes. The resulting Sa@HMMSN@PM exhibited pH-responsive Sa release, preserved PD-L1 blocking activity, and enhanced tumor-cell-selective uptake. Mechanistically, Mn2\u207a released from HMMSN promoted cGAMP production, while Sa further enhanced STING phosphorylation, leading to robust STING activation. Sa@HMMSN@PM showed enhanced tumor accumulation, superior tumor growth inhibition and prolonged survival in both subcutaneous and orthotopic NSCLC mouse models. Further mechanistic studies demonstrated increased IFN-\u03b2, CXCL10, TNF-\u03b1, IL-6, and IFN-\u03b3 levels, together with enhanced CD4\u207a and CD8\u207a T-cell infiltration. Importantly, Sa@HMMSN@PM exhibited favorable biosafety without obvious systemic toxicity. Overall, this biomimetic Mn2\u207a-amplified STING nanoagonist provides a promising strategy for integrating innate immune activation with immune checkpoint blockade for enhanced NSCLC immunotherapy.",

Nevertheless, its therapeutic efficacy remains constrained by the hostile tumor microenvironment (TME), typified by acidity and an immunosuppressive milieu. Here, multifunctional microspheres (RC6CaAlgMS) were developed to neutralize the acidic TME and relieve immunosuppression. The uniform-sized calcium alginate microspheres were fabricated using microfluidic technology, incorporating pH-responsive CaCO3 nanocarriers to efficiently encapsulate R848 and C6-ceramide (C6). Their physicochemical properties were characterized, and the embolization efficiency was validated using decellularized liver and rabbit kidney models. Furthermore, their antitumor activities and mechanism were evaluated in both in vitro and in vivo. R848 and C6 were efficiently encapsulated into RC6CaAlgMS, where they acted synergistically to reprogram tumor-associated macrophages (TAMs) toward an M1-like phenotype and to enhance both exosome secretion and exosome-mediated antigen cross-presentation. RC6CaAlgMS produced uniform vascular embolization and efficiently occluded the renal arterial branches. In vitro studies demonstrated that RC6CaAlgMS synergized with DOX-based chemotherapy to suppress the growth of murine HCC by neutralizing acidic TME and remodeling the immune landscape. When combined with PD-L1 blockade therapy, DOX-loaded RC6CaAlgMS effectively inhibited both primary and distant tumors, eliciting an abscopal-like effect driven by enhanced antigen dissemination and T-cell priming. In an orthotopic rat TACE model, the combination of DOX-loaded RC6CaAlgMS with PD-L1 blockade achieved complete tumor eradication. Collectively, this study establishes a multifunctional microsphere platform that effectively remodels and overcomes the post-TACE immunosuppressive TME, offering a potent strategy for integrating embolization with immunotherapy in HCC.",

Here, we report a rationally engineered class of lipid-antigen conjugates that co-enhance lymph node (LN) targeting and antigen-presenting cell (APC) uptake through molecular-level structural optimization. By systematically varying lipid tail composition and linker chemistry, we identify a lead construct (dOA-K-O) incorporating a dioleic acid (dOA) lipid tail and an L-lysine (K) linker, which outperforms the clinically used DSPE-PEG2000 conjugate (DSPE-O). Mechanistically, the positively charged L-lysine linker promotes albumin binding while reducing excessive self-assembly, enhancing lymphatic trafficking and facilitating APC internalization. In vivo, dOA-K-O elicits robust antigen cross-presentation and induces an 8-fold increase in antigen-specific CD8+ T cell responses compared to unmodified antigenic peptide and 3-fold higher than DSPE-O. This enhanced cellular immunity translates into marked tumor suppression in both prophylactic and therapeutic B16-OVA melanoma models. Our results establish a design paradigm in which linker chemistry and lipid tail composition are synergistically optimized to boost the immunogenicity of peptide vaccines for cancer immunotherapy, which may provide a chemical and structural basis for the optimization of peptide-based vaccine delivery systems.",

Despite substantial therapeutic advances, treatment resistance and disease relapse continue to affect a significant fraction of patients. The mechanisms by which the tumour microenvironment and other factors influence RTX efficacy are not fully elucidated. Herein, we hypothesized that CD20+ extracellular vesicles (EVs) shed by B cell lymphomas are recognized by RTX forming immune complexes that modulate natural killer (NK) cell activity via Fc\u03b3 receptor (Fc\u03b3R) interactions. EVs isolated from lymph node explants and plasma samples of B-NHL patients contained abundant CD20+ vesicles, which were particularly enriched in advanced disease. RTX specifically bound CD20 on these EVs, generating EV-RTX immune complexes. Functional studies employing EVs from a B-NHL cell line and from patient-derived samples demonstrated that, whereas EVs suppressed NK cell activation and cytotoxicity, EV-RTX immune complexes reversed this inhibitory effect and enhanced NK cell effector functions. Indeed, EV-RTX immune complexes specifically triggered Fc\u03b3RIIIa-dependent NK cell activation, evidenced by increased Syk phosphorylation, CD69 expression, and enhanced lytic activity against target cells. Our findings uncover a previously unrecognized mechanism by which RTX, through the formation of immune complexes with CD20+ EVs, promotes NK cell activation and may enhance therapeutic efficacy. More broadly, these results demonstrate that antibody binding can endow EVs with novel immunomodulatory properties, revealing a potential mechanism by which therapeutic antibodies reshape EV function and influence anti-tumour immunity.",

Superficial and deep cervical lymph nodes collect CSF in mice, but the exact and quantified routes are unknown. Recently, we simultaneously visualized cervical, sacral and iliac lymph nodes via serial imaging on the intrathecal [64Cu]Cu-albumin positron emission tomography. Paravertebral lymph nodes might act as sentinels to monitor the CSF, brain, and spinal cord. We used 64Cu-labeled Escherichia coli extracellular vesicles, outer membrane vesicles (OMVs), as lymph node seekers for intrathecal administration and quantified the differential amounts of various paravertebral lymph nodes along the axis of the brain and spinal cord in mice. The quantified results revealed 77.3% in superficial and deep cervical lymph nodes, 11.4% in abdominal/pelvic lymph nodes and 11.3% in sacral lymph nodes. Click-labeled [64Cu]Cu-OMVs were drained to reach and stop at the lymph nodes on serial quantification. The cervical lymph nodes drained most of the OMV-laden CSF, which is proportional to the surface areas of the brain (70%) and spinal cord in mice. We propose that all paravertebral lymph nodes monitor the segmental regions of the brain and spinal cord as immediate sentinel lymph nodes against the central nervous system.",

Liquid biopsy, a noninvasive approach analyzing tumor-derived components in bodily fluids, has emerged as a promising tool in OC management. This review summarizes advances in liquid biopsy technologies, focusing on circulating tumor DNA (ctDNA) and circulating tumor cells (CTCs). ctDNA enables minimally invasive assessment for diagnosis, prognosis, treatment guidance (e.g., BRCA1/2-targeted therapy), minimal residual disease (MRD) detection, and monitoring of tumor evolution. CTCs, particularly clusters, provide insights into metastasis and therapeutic response. Emerging modalities such as tumor-educated platelets (TEPs), circular RNAs (circRNAs), and exosomes and protease activity-based liquid biopsy also show diagnostic and prognostic potential.

This review highlights recent advances in exosome biology, cargo-sorting mechanisms, and engineering strategies designed to enhance therapeutic delivery and targeting within the central nervous system. Particular emphasis is placed on the application of engineered exosomes in neurodegenerative diseases, stroke, spinal cord injury, neuropathic pain, and neuroinflammatory disorders. In addition, we discuss how exosomes compare with conventional delivery platforms and critically examine the major barriers limiting their clinical translation, including heterogeneity, scalability, reproducibility, purity, and regulatory standardization. By integrating mechanistic insights with translational perspectives, this review provides a framework for the rational design and future clinical implementation of exosome-based nanomedicines for neurological disorders. Relevant literature was identified through searches of PubMed, Scopus, Web of Science, and Google Scholar. Publications available from database inception through [Month Year] were screened using combinations of keywords including \"exosomes,\" \"extracellular vesicles,\" \"neurological disorders,\" \"brain-targeted delivery,\" \"exosome engineering,\" \"drug delivery,\" and \"clinical trials.\" Additional relevant articles were identified through manual searches of reference lists from selected studies and recent reviews. Exosomes are tiny natural particles released by cells that act as messengers, carrying proteins and genetic material between cells. Scientists are increasingly studying these particles because they may help deliver medicines to the brain and spinal cord, where many treatments struggle to reach due to protective barriers. This review explains how exosomes are formed, how they can be modified to carry drugs or therapeutic molecules, and how they may help treat diseases affecting the nervous system, including Alzheimer\u2019s disease, Parkinson\u2019s disease, stroke, multiple sclerosis, spinal cord injury, and certain neuropsychiatric disorders.We also discuss the advantages of exosomes compared with conventional drug delivery systems and summarize recent advances in engineering strategies that improve their targeting abilities. Although laboratory studies have produced encouraging results, many challenges remain before exosome-based therapies can become routine treatments. These include difficulties related to large-scale production, quality control, safety, and ensuring that exosomes reach the desired tissues without causing unwanted effects.In addition, this review highlights current clinical studies and discusses the steps needed to translate these discoveries into real-world therapies. Overall, exosomes represent an exciting and rapidly evolving area of research that may contribute to the development of safer and more effective treatments for neurological disorders in the future.",
"42576909": "ID: 42576909\nTitle: Mitochondria-targeted peptide-engineered bimetallic nanozymes enable ferroptosis-sensitized cuproptosis for melanoma therapy.\nAbstract: Developing nanotherapeutics to circumvent intrinsic apoptosis resistance in cancer remains a key challenge in oncology. Cuproptosis, a non-apoptotic cell death modality, has emerged as a promising alternative, yet its therapeutic efficacy is frequently limited by robust intracellular antioxidant defense systems. Here, we developed an ultrasmall (ca.10\u202fnm) mitochondria-targeted bimetallic nanozyme (RMOCZ) for synergistic ferroptosis-cuproptosis therapy against malignant melanoma. The Cu/Zn bimetallic core, functionalized with a chimeric mitochondrial targeting peptide, serves as both a pH-responsive copper reservoir and a dual-enzyme mimetic (peroxidase and glutathione oxidase). Upon endolysosomal acidification, RMOCZ disassembles to co-release copper ions and oridonin (ORI). The nanozyme oxidizes intracellular glutathione (GSH), a process significantly accelerated by co-delivered ORI. This disruption of redox homeostasis not only triggers ferroptosis by compromising cellular antioxidant capacity but also amplifies peroxidase-mediated reactive oxygen species (ROS) production, sensitizing tumor cells to copper-induced cytotoxicity. Concurrently, RMOCZ induces ferritinophagy to mobilize the endogenous labile iron pool and exacerbate lipid peroxidation. These events culminate in sustained copper-iron dual-ion overload. Following subsequent mitochondrial trafficking, the accumulated copper ions trigger canonical cuproptotic events, including the degradation of iron-sulfur (Fe-S) clusters and aberrant oligomerization of lipoylated DLAT. This irreversible mitochondrial dysfunction triggers potent immunogenic cell death (ICD) with robust damage-associated molecular patterns (DAMPs) release. In situ immunohistochemical analyses confirm that this RMOCZ-induced ICD profoundly remodels the immunosuppressive\u00a0microenvironment, promoting CD86+ antigen-presenting cell maturation and enhancing intratumoral infiltration of CD3+ and CD8+ T cells. In vivo, RMOCZ demonstrates substantial melanoma regression with negligible systemic toxicity, providing a promising strategy for treating apoptosis-resistant refractory malignancies.",

Such products have been utilized for hemostatic purposes and regenerative medicine. Poor shelf life, high cost of storage, immune risk, and constant need for adequate donors have led to the desire for biomaterials that mimic platelet function. Artificial platelets, such as platelet-membrane coated nanoparticles (NPs), platelet-like particles, SynthoPlate, and GRGDS-PEG-coated polyurethane NPs, have been designed to mimic platelet functionality and aid in hemostasis. Platelet product and artificial platelet function can be further leveraged for regenerative medicine and wound healing as they interact with activated platelets and fibrin at the region of interest, highlighting their therapeutic potential. Example regenerative applications of both platelet products and artificial platelets include osteogenesis, angiogenesis, soft tissue and dermal healing, and drug or cell delivery. Some platelet products have reached clinical trials, but most of the biomaterial based approaches are still in preclinical testing.

However, the blood-brain barrier (BBB) remains a formidable obstacle, restricting the delivery of most therapeutic molecules. To address this, we developed a non-invasive treatment strategy using engineered exosomes. Specifically, we fabricated FGF1-loaded exosomes functionalized with the rabies virus glycoprotein (RVG) peptide (FGF1-RVG Exo). This platform facilitates selective, neuron-targeted delivery of FGF1 to the ischemic penumbra via RVG-mediated transcytosis. In a diabetic stroke mouse model, FGF1-RVG Exo exhibited superior pharmacological efficacy compared to free FGF1, achieving robust therapeutic outcomes with only once-weekly administration. Notably, a single dose during the acute phase elicited a sustained hypoglycemic effect lasting up to two weeks and effectively ameliorated systemic insulin resistance. Locally, the accumulation of exosomes within the lesion led to a significant reduction in infarct volume and cell apoptosis, while promoting neovascularization and the recovery of motor and cognitive functions. This brain-targeted strategy achieves a peripheral-central synergistic modulation, addressing the multi-target requirements of diabetic stroke management. Collectively, our findings provide a novel paradigm for treating diabetic ischemic stroke and a potent strategy for the targeted delivery of growth factors to the central nervous system.",

As principal mediators of intercellular communication within the tumor microenvironment, secretory autophagosomes (SAPs) propel breast cancer progression and metastasis by modulating the establishment of the pre-metastatic niche, thereby positioning them as highly promising biomarkers for breast cancer. However, the paucity of accurate and simplified quantitative tools has impeded the direct detection of circulating SAPs. This study presents a sensing platform that couples nanozyme cascade catalysis with a covalent organic frameworks (COFs)-derived nanohydrogel (CGNH) for precisely assessing trace-level SAPs. The AuNBP@PtPd-MoS2 nanozyme, via its stereoconfiguration and trimetallic synergy, recapitulates the dual enzyme-mimicking activities of GOx/CAT. Hence, it enables self-sustained interfacial charge transfer. As a signal probe, it efficiently accelerates self-cascade catalysis and electrochemical mass transfer. Additionally, CGNH creates an ideal interface for SAPs enrichment and cascade catalysis, featuring a hierarchical pore structure, a hybrid conductive network, and suitable biocompatibility. With self-assembled antifouling peptide nanoparticles (APNP) as a shielding barrier, the platform reliably detects SAPs in intricate biological matrices verified using cellular, murine and clinical specimens. Compared with conventional biomarkers, SAPs produce more informative readouts on disease progression. This electrochemical platform differentiates between benign and malignant breast diseases and healthy controls with high diagnostic accuracy (AUC\u202f=\u202f0.962), especially for gray-zone differentiation and metastasis forecasting. This study offers new avenues for SAPs-based liquid biopsy to identify signs of breast cancer metastasis and is expected to become a reliable non-invasive tool for personalized breast cancer management.",

This study aimed to enhance the sustained release, targeting, and efficacy of AMC via developing an intratumoral, in situ pH-responsive AMC-loaded novasome (IPANF) hydrogel. The optimal AMC-novasome was tailored using Design-Expert\u00ae software and subsequently incorporated into a chitosan/glyceryl monooleate mixture to develop IPANF. The in vivo anti-tumour efficacy and safety profile of the IPANF were evaluated using an Ehrlich ascites carcinoma model. Within 24\u2009h, the IPANF formulation exhibited a significantly sustained drug release by 65.31% compared to the free AMC suspension. The intratumoral IPANF resulted in a profound 96.08% reduction in tumour volume, a 70.46% recovery in body weight, and a suppression of the CA 15-3 and CA 27-29 levels by 92.66% and 91.23%, respectively.

It is identified by thickening of the dermis, connective tissue affected by collagen accumulation, and vascular injuries that induce hypoxia. The present study aimed to determine whether extracellular vesicles (EVs) from adipose-derived stem cells (ADSCs) attenuated bleomycin-induced skin fibrosis and oxidative stress in scleroderma. ADSCs and their EVs were separated and a bleomycin-induced SSc mouse model was constructed. High-throughput sequencing was employed to study abnormal expression of circular RNAs in SSc skin tissues with or without ADSC-EV treatment. The regulatory mechanism and targets were studied using bioinformatics analysis, luciferase reporting analysis, angiogenic differentiation experiments, and RT-qPCR detection analysis. EVs from ADSCs were successfully isolated. The exosome treatment prevented dermal thickening and fibrosis in bleomycin-induced scleroderma. In addition, circ-Zfyve9 was demonstrated to have an important function in ADSC-EV-mediated skin tissue protection. GPX4 and miR-135 were shown to be downstream targets of circ-Zfyve9. Overexpressing miR-135 or downregulating GPX4 reversed the promotion effects of circ-Zfyve9 on angiopoiesis by increasing lipidosome ROS in EPCs under hypoxic conditions. Overexpressing miR-135 or downregulating GPX4 reversed the inhibition effect of circ-Zfyve9 on fibrosis in myofibroblasts under hypoxic conditions.

Conventional treatments, including immunotherapies and targeted inhibitors, face three main challenges: tumor heterogeneity, drug resistance, and systemic toxicity. Nucleic acid therapeutics (NATs) encompass a diverse array of DNA- and RNA-based tools, including small interfering RNA (siRNA), microRNA (miRNA), messenger RNA (mRNA), antisense oligonucleotides (ASOs), and clustered regularly interspaced short palindromic repeats (CRISPR)-associated (Cas) systems. These tools are central to developing precision oncology approaches that operate through direct gene regulation, mutation correction, and immune system reprogramming. The clinical application of NATs currently faces three main obstacles, which include their vulnerability to enzymatic degradation, their limited ability to penetrate tissues, and their tendency to cause off-target effects. The field has progressed through the implementation of nanoformulation techniques, which utilize lipid-based polymeric and metallic carriers together with exosomes and DNA origami, and hybrid nanostructures as new platforms to enhance the stability of drugs and their cellular absorption and targeted delivery to tumors. The scientists developed functionalized nanocarriers by combining targeting ligands with materials that could respond to specific environmental changes, which allowed them to manage drug distribution and release patterns throughout the tumor microenvironment. This review focuses on establishing a direct connection between nucleic acid design and nanotechnology through an analysis of mechanistic details and progress in preclinical and clinical research, and the difficulties encountered during the progress to practical applications. The research demonstrates how artificial intelligence and bioinspired nanocarriers and multi-omics data integration create new opportunities for developing personalized adaptive nanogenetic treatment methods, which will treat lung cancer. The current advancements indicate that we are approaching a transformative era in which nanomedicine and nucleic acid therapeutics will enable safe genetic alterations of cancer through targeted therapeutic applications.",

A key approach involves reprogramming tumor-associated macrophages (TAMs) from a protumorigenic M2 phenotype to an antitumorigenic M1 state. However, elevated lactate concentration in the TME not only sustains the M2 phenotype but also impairs therapeutic efficacy. To address this challenge, we developed an in situ injectable carboxymethyl chitosan/oxidized sodium alginate (CMCS/OSA) hydrogel with pH-responsive release properties, coloaded with another nanosized active polysaccharide \u03b2-glucan and a lactate-depleting agent lactate oxidase (LOX). Under the acidic conditions of the TME, Schiff base bonds within the hydrogel matrix dissociate, triggering the controlled release of \u03b2-glucan nanoparticles and LOX. The \u03b2-glucan nanoparticles specifically target TAMs via the dendritic cell-associated C-type lectin 1 (Dectin 1) receptor, facilitating their phenotypic conversion from M2 to M1. Simultaneously, the released LOX continuously degrades lactate, preventing the reversion of TAMs back to the M2 phenotype. Collectively, our results demonstrated that this nanocomposite polysaccharide hydrogel system effectively promoted and maintained TAM polarization toward the M1 phenotype through the synergistic effects of immune modulation and metabolic regulation, ultimately enhancing the efficacy of tumor immunotherapy.",

Protein-based nanocarriers, such as the heavy chain of human ferritin (FTH1), facilitate transferrin receptor-mediated transport across the blood-brain barrier. Here, we present multifunctional FTH1 nanocages as a unified nanoplatform for dual-drug chemotherapy and molecular imaging. The nanocages achieve > 98\u202f% gallium-68 labeling efficiency and enable pH-responsive release of doxorubicin and paclitaxel. In isocitrate dehydrogenase (IDH)-wildtype and IDH-mutant tumor models in ovo, FTH1 nanocages exhibit robust intracerebral distribution, tumor accumulation, and enhanced therapeutic efficacy. Dual-drug nanocages significantly reduce tumor growth (p\u202f<\u202f0.001), with a stronger effect in the IDH-mutant model (p\u202f<\u202f0.001), and improve embryo survival. Kinomic profiling reveals broad suppression of AGC and CMGC kinase families, consistent with attenuation of pro-survival and cell-cycle signaling, particularly in IDH-mutant models. These findings suggest treatment-associated kinase network adaptation linked to the IDH status of the models, consistent with increased therapeutic vulnerability, and support further evaluation of FTH1 nanocages as a platform for improved glioma treatment.",

Herein, we report the synthesis of a cysteamine-functionalized poly (N-isopropylacrylamide-co-lithocholic acid) based amphiphilic copolymer, (poly(NIPAM-co-MELCA-Cys)), with thermo- and pH-responsive behavior and its stabilized silver nanoparticles (AgNPs). The copolymer exhibits primary and secondary critical aggregation concentration (CAC) at 3.84 x10-4 and 1.51x10-3 wt%, respectively, in aqueous media, together with tunable lower critical solution temperature (LCST) behavior. Under optimized alkaline conditions, poly(NIPAM- co- MELCA- Cys) facilitates the formation of spherical AgNPs with nearly uniform distribution and exhibit stability for more than a year. The colloidal stability of capped AgNPs was assessed in physiological media (NaCl, PBS, and FBS) using UV-Visible spectroscopy, DLS, and zeta potential measurements. Optical and morphological properties were analyzed by UV-visible spectroscopy, HR-TEM, DLS, XPS, and zeta potential techniques. MTT assay revealed dose-dependent cytotoxicity in KB cells, while 3T3-L1 cells showed lower sensitivity.

Extracellular vesicles (EVs) mediate intercellular molecular communication and are deeply involved in the initiation and progression of GC. Here, we focus on exosomes, the most thoroughly studied EV subtype (30-150\u00a0nm), and examine their biological roles in GC and their potential for clinical translation. We construct an exosome-derived molecular network of GC progression across six dimensions: promoting tumor cell proliferation, orchestrating an immunosuppressive microenvironment, inducing tumor angiogenesis, remodeling the extracellular matrix, guiding metastasis, and mediating drug resistance. In this review, we systematically summarize exosome-derived non-coding RNAs and proteins as biomarkers for early detection and prognosis of GC. Moreover, emerging strategies targeting exosomes or employing exosomes as delivery vehicles are discussed. Finally, we address current challenges in exosome research and propose future directions. This review aims to serve as a reference for basic research and clinical translation in GC, emphasizing that deciphering exosome-mediated intercellular dialogue is essential for understanding the molecular underpinnings of tumor progression and developing novel intervention strategies.",

"42628189": "ID: 42628189\nTitle: Hair regeneration in alopecia using adipose-derived mesenchymal stem cells secretome: A systematic review of experimental and clinical evidence.\nAbstract: Alopecia is characterized by progressive follicular miniaturization and impaired regenerative capacity associated with abnormal hair cycling. Current therapies often provide limited or temporary benefits, highlighting the need for regenerative strategies targeting follicular restoration. This systematic review summarizes current experimental and clinical evidence regarding the regenerative potential of the secretome from adipose tissue-derived mesenchymal stem cells (AT-MSCs) as a cell-free therapeutic strategy for hair regeneration. In contrast to conventional cell transplantation, the biological effects of AT-MSCs secretome are mainly mediated through paracrine mechanisms involving a variety of bioactive molecules, including growth factors, cytokines, and extracellular vesicles such as exosomes. Evidence from experimental models indicates that treatment with MSCs-derived secretome supports dermal papilla cell expansion and triggers intracellular signaling mechanisms that regulate hair follicle growth, with the Wnt/\u03b2-catenin pathway playing a major role. In preclinical animal studies, administration of the secretome has been shown to accelerate the transition of hair follicles from the telogen phase to the anagen phase, accompanied by increased follicle density and improved perifollicular vascular development. Preliminary clinical findings also suggest improvements in hair density and hair shaft thickness, especially when secretome therapy is applied together with microneedling procedures or standard therapeutic approaches. The observed regenerative responses are believed to be mediated by several angiogenic growth factors, including vascular endothelial growth factor (VEGF), insulin-like growth factor-1 (IGF-1), and hepatocyte growth factor (HGF). In addition, these effects involve signaling pathways that regulate immune responses and inhibit apoptosis within the follicular microenvironment. However, variations in secretome production techniques, dosage approaches, and clinical research design restrict the interpretation of available data. Validating the safety, effectiveness, and therapeutic significance of AT-MSCs secretome in the treatment of alopecia requires extensive, well-controlled clinical trials and established manufacturing procedures.",

Herein, the surface-engineered exosomal nanoplatform for targeted glioma therapy is functionalized glioblastoma-derived exosomes with the epidermal growth factor receptor (EGFR)-targeting GE11 peptide and loading them with peonidin (PN), a naturally occurring anthocyanin with anticancer potential. The engineered Exo-GE11/PN nanoparticles exhibited favorable physicochemical characteristics, including nanoscale size distribution, high encapsulation efficiency, colloidal stability, and preserved exosome morphology. GE11 functionalization significantly enhanced cellular uptake in EGFR-overexpressing glioma cells, facilitating efficient intracellular delivery of PN. In vitro studies demonstrated that Exo-GE11/PN effectively suppressed glioma cell proliferation, migration, and invasion while promoting apoptotic cell death. Mechanistic investigations revealed that the formulation attenuated EMT through downregulation of SNAI1 and modulation of the PI3K/Akt/NF-\u03baB signaling pathway, accompanied by restoration of epithelial markers and suppression of mesenchymal markers. Furthermore, Exo-GE11/PN significantly reduced tumor growth and improved survival in glioma-bearing mice without inducing clear systemic toxicity, confirming its biocompatibility and therapeutic efficacy. Collectively, these findings highlight the importance of exosome surface engineering for targeted drug delivery and demonstrate that GE11-functionalized exosomes serve as an effective biointerface-mediated carrier for peonidin. This biomacromolecular nanoplatform offers a promising strategy for EGFR-targeted glioblastoma therapy through the suppression of EMT-associated oncogenic signaling pathways.",

However, their specific roles and mechanisms in Alzheimer's disease (AD) therapy have not yet been systematically investigated. In this study, the rabies virus glycoprotein-targeting peptide (RVG-29) was conjugated to the surface of young plasma-derived EXOs to construct RVG-engineered EXOs (RVG-EXOs), and their therapeutic potential and underlying mechanisms in AD models were systematically evaluated. In 3\u00d7Tg AD model mice, exogenous administration of young plasma-derived EXOs and their engineered product (RVG-EXOs) revealed that RVG-EXOs could more efficiently enter brain tissue and target neurons, significantly reduce A\u03b2 plaque and phosphorylated Tau (P-Tau) pathological deposition, restore synaptic structure, promote neuronal survival, and improve cognitive behavior. Mechanistic studies demonstrated that RVG-EXOs inhibited RPTOR expression, thereby activating the autophagy pathway and promoting the clearance of pathological proteins. Both in vitro and in vivo experiments confirmed that overexpression of RPTOR significantly suppressed the therapeutic effects of RVG-EXOs. single-cell transcriptomic profiling further revealed that RVG-EXOs not only increased neuronal proportion and modulated excitatory/inhibitory neuronal balance but also reshaped the microglial landscape by reducing deleterious disease-associated while increasing homeostatic surveillant microglia. In summary, this study not only reveals for the first time the potential value of young plasma-derived EXOs in AD treatment but also, through RVG engineering strategies and the elucidation of the RPTOR-autophagy mechanism, provides new insights for targeted therapy of neurodegenerative diseases.",

Previous studies have shown that extracellular vesicles (EVs) derived from mesenchymal stem cells (MSCs) and human hair outer root sheath cells (HHORSCs) can enhance hair follicle development, ameliorate androgenetic alopecia, and support the inductive capacity of dermal papilla cells. However, the regulatory effects of HHORSC-derived EVs (HHORSC-EVs) and human bone marrow mesenchymal stem cell-derived EVs (HBMMSCEVs) on HFSCs remain unclear. HFSCs were treated with HHORSC-EVs or HBMMSC-EVs for 10 days. The effects of EVs on HFSC proliferation, apoptosis, and differentiation were evaluated using a Cell Counting Kit8 assay, flow cytometry, and immunofluorescence staining, respectively. EVs from both HHORSCs and HBMMSCs did not enhance hair follicle growth by improving the proliferation of HFSCs, but rather by inhibiting apoptosis. In addition, HBMMSC-EVs further promoted HFSC stemness maintenance by upregulating K15 and CD34 expression. HFSCs may serve as a novel target for both HHORSC-EVs and HBMMSC-EVs, highlighting their therapeutic potential for hair loss disorders. This study offers new insights into developing EV-based therapies for hair loss disorders.",

However, how microRNAs (miRNAs) regulate autophagy in HCC remains incompletely understood. In this study, we identified microRNA-486-5p (miR-486-5p) as a tumour-associated microRNA that is enriched in circulating exosomes derived from patients with HCC. Elevated miR-486-5p promoted proliferation and suppressed apoptosis in HCC cell lines under stress conditions. Mechanistically, miR-486-5p directly targets the 3' untranslated region of the phosphatase and tensin homologue (PTEN) gene, thereby decreasing the production of the PTEN protein and consequently leading to the activation of the protein kinase B (AKT)/mammalian target of rapamycin (mTOR) signalling pathway. This phenomenon was accompanied by the inhibitory phosphorylation of unc-51\u00a0like autophagy-activating kinase 1 (ULK1), which resulted in impaired autophagy. The pharmacological inhibition of AKT or mTOR led to the restoration of autophagy and the attenuation of miR-486-5p-driven growth and survival advantages. Furthermore, the transcription factor MYB was found to bind the promoter of ankyrin-1 (ANK1), the host gene of miR-486-5p, and to drive its expression. In an orthotopic liver tumour model, the liver-targeted delivery of miR-486-5p accelerated tumour expansion, an effect that was reversed by AKT or mTOR blockade. Collectively, these findings delineate a MYB/miR-486-5p/PTEN/AKT/mTOR signalling axis that constrains autophagy to facilitate HCC progression, suggesting potential avenues for biomarker development and therapeutic intervention.",

Realizing this potential depends on technologies that can isolate, detect, and deliver exosomes with high specificity and efficiency. Affinity-based strategies that exploit the molecular recognition of antibodies and aptamers are central to this effort. In this review, we analyze how these ligands are advancing exosome research. We first examine isolation methods, benchmarking affinity capture against conventional techniques and weighing trade-offs among yield, purity, and vesicle integrity. We next explore detection technologies, in which antibody- and aptamer-based biosensors enable ultrasensitive, multiplexed, and point-of-care assays. Finally, we discuss the therapeutic frontier, where ligand-mediated surface functionalization creates targeted delivery vehicles. In preclinical models, engineered exosomes can traverse biological barriers and deliver multimodal payloads, indicating potential therapeutic avenues for cancer as well as neurodegenerative and metabolic disorders. Taken together, we highlight the synergy between affinity ligands and exosome science and outline key challenges for clinical translation.",

Through this process, they can modulate the biological functions of recipient cells. Age-related ophthalmic diseases, including age-related macular degeneration (AMD), dry eye disease (DED), and age-related cataract (ARC), are degenerative ocular conditions whose incidence increases with age and are associated with chronic inflammation, oxidative stress, dysregulated angiogenesis, tissue fibrosis, epithelial injury, and apoptosis. Diabetic retinopathy (DR), although not classically defined as an age-related ophthalmic disease, is also briefly discussed in this review as an age-associated metabolic retinal comorbidity. Existing clinical treatments have several limitations, including the need for repeated administration, variable therapeutic responses, and potential adverse effects. Because of their biocompatibility, low immunogenicity, modifiable cargo and potential for local delivery, exosomes are being investigated as therapeutic agents and drug delivery vehicles in ophthalmology.

In this study, pH-sensitive, core-shell hydrogel microcapsules were designed and fabricated using a BUCHI B-390 microsphere preparation device via electrostatic interactions and hydrogen bonds. Olsalazine sodium was encapsulated in the microcapsules, allowing for pH-responsive drug release in colon tissue for UC treatment in mice. XRD studies demonstrated the amorphous state of the drug in the formulation. The preparation of SCO microcapsules was optimized based on the drug encapsulation efficiency and the drug loading capacity, with the S2C1O microcapsule having the highest drug encapsulation efficiency (59.2%) and drug loading capacity (21.3%), and the production yield was approximately 62.5%. The degradation experiment results indicated that the alginate/CMCS hydrogel shell has anti-resistant and colon-targeted properties, with minimal drug leakage under acidic conditions (0.1% release at 2 h, pH 1.2) and rapid, controlled release at colonic pH (7.4) (cumulative release of 68.7% at 12 h), protecting the drug from gastric degradation. An in vivo experiment suggested that treatment with these microcapsules in UC mice significantly reduced inflammatory markers (NF-\u03baB p65 was reduced by 18.8% relative to the free drug group) and histological damage in UC models relative to free drug administration. The improved therapeutic efficacy is linked to precise localization in inflamed tissue, reducing systemic exposure and off-target effects.

Here we successfully synthesized curcumin (CUR) loaded polyethylene glycol (PEG) functionalized magnetic iron oxide nanoparticles (Fe3O4@PEG-CUR-NPs) by a green biogenic approach using Hibiscus rosa-sinensis flower extract and evaluated as a multifunctional platform for controlled drug delivery and cancer therapy. UV-Vis, FTIR, PXRD, SEM, TEM, DLS, TGA and VSM characterizations have been performed comprehensively to confirm the successful fabrication of crystalline, spherical nanoparticles with average size of 10-15\u00a0nm, excellent colloidal stability (zeta potential\u2009-\u200931.5\u00a0mV) and retained magnetic responsiveness with saturation magnetization of 28.30\u00a0emu/g. The nanocarrier showed significant pH-responsive drug release, with 90.55% cumulative CUR release under acidic conditions (pH 4.5) compared to 44.5% at physiological pH (7.4), indicating its possibility for tumor-targeted delivery. Release kinetic studies revealed that the drug release was mainly diffusion-controlled and followed a non-Fickian transport mechanism. Besides, Fe3O4@PEG-CUR-NPs showed good anti-inflammatory effect with IC50 value of 25.10\u00a0\u03bcg/mL, which was significantly better than diclofenac (IC50\u2009=\u200982.20\u00a0\u03bcg/mL).

We evaluated a serum-free CELLine AD 1000 bioreactor workflow for producing EVs from four ovarian cancer-related (OC-related) cell lines (OVCAR4, CaOV3, PA1, SW626) and human dermal fibroblasts (HDFa) as a non-cancer control. Cells were adapted to CDM-HD serum-free medium and maintained for eight weeks with twice-weekly conditioned-medium collection. EVs were isolated by differential ultracentrifugation followed by size-exclusion chromatography and characterized by nanoparticle tracking analysis, imaging flow cytometry, Western blotting, and transmission and scanning electron microscopy. Across longitudinal harvests, OC-related cultures generally produced higher EV particle concentrations and A280-based bulk protein estimates than HDFa, while individual cell lines showed distinct production profiles and membrane-associated growth patterns. A parallel OVCAR4 T-175 flask, maintained in its original serum-containing medium, provided a contextual reference indicating higher per-collection EV particle recovery with the bioreactor, although this was not a matched culture-format comparison. EV-enriched preparations contained vesicle-like particles, with modal diameters of approximately 96-128 nm. Using imaging flow cytometry, the CD9 signal was higher in OC-related EVs and CD63 was most prominent in HDFa; CD9 and CD63 were also detected in OC-related EV lysates by Western blotting. Because one bioreactor was operated per cell line, these findings should be interpreted as preliminary and descriptive rather than statistically comparative. Overall, this study provides a practical serum-free CELLine AD 1000 workflow for generating characterized OC-related EV material for downstream analytical studies.",

However, the low in vitro maturation rate of their oocytes significantly limits the efficiency of assisted reproductive technologies. Curcumin (CUR), known for its bioactive functions, including antioxidant and anti-inflammatory properties, suffers from low water solubility and bioavailability, which restricts its practical applications. This study aimed to develop a curcumin-loaded bovine milk-derived exosome nanodelivery system (CUR-mEXOs) and investigate its effects on the in vitro maturation of yak oocytes and the embryonic development of parthenogenetic embryos, leveraging its natural biocompatibility and targeted delivery properties. The results indicated that the isolated mEXOs exhibited typical exosome morphology and nanoscale particle size characteristics and were effectively internalized by the oocytes. During in vitro maturation, treatment with 10 \u03bcM CUR produced optimal outcomes. Compared to free CUR, CUR-mEXOs significantly enhanced the cumulus expansion index and the rate of first polar body expulsion, reduced intracellular ROS accumulation and mitochondrial superoxide levels, and improved mitochondrial function and spindle morphology, while simultaneously upregulating the expression of factors related to mitochondrial autophagy and oocyte maturation. Following intervention with the mitochondrial autophagy inhibitor CsA, the promotive effect of CUR-mEXOs was significantly diminished, leading to increased blastocyst apoptosis and a decrease in the total cell count. In summary, CUR-mEXOs can enhance the quality of in vitro maturation of yak oocytes and their embryonic developmental capacity following parthenogenesis by regulating mitochondrial autophagy. This study established an experimental foundation for optimizing the in vitro maturation system of yak oocytes and developing strategies for the delivery of natural bioactive substances. Additionally, this study provides a theoretical basis for enhancing the efficiency of assisted reproductive technologies in yaks.",

Genetic and signaling alterations within tumor cells explain part of this transition, but they do not fully account for the coexistence of different differentiation states within the same molecular subtype or even within the same lesion. Increasing functional evidence indicates that dedifferentiation is maintained by reciprocal interactions between malignant cells and the immune, stromal, metabolic, and inflammatory microenvironment. Cancer-associated fibroblast glycolysis and lactate release, IL-6/CXCL8-driven inflammatory signaling, hypoxia, transforming growth factor-beta signaling, and tumor-associated macrophage feedback can suppress thyroid lineage programs while promoting plasticity, invasion, and treatment resistance. Here, we synthesize mechanistic studies supported by genetic perturbation, co-culture, pharmacologic blockade, iodine-uptake assays, animal models, or patient-level radioiodine endpoints. We distinguish functional dedifferentiation from epithelial-mesenchymal transition, stemness, and lymph-node metastasis, and discuss therapeutic strategies that combine tumor-cell redifferentiation with targeting of microenvironmental feedback to restore durable radioiodine sensitivity.",

Extracellular vesicles (EVs) are nano-sized, membrane-enclosed particles released by nearly all cell types that carry selectively sorted bioactive cargo capable of influencing the behavior and fate of recipient cells. Although their molecular composition is shaped by their cells of origin, cargo loading is a regulated process that contributes to EV-mediated intercellular communication and cell-specific targeting. In TC, EVs have emerged as important mediators of tumor progression and microenvironment modulation. Recent advances underscore the diagnostic and prognostic value of EVs as non-invasive biomarkers, particularly through the detection of EV-associated non-coding RNAs, proteins, lipids, and other molecular signatures. However, methodological variability and limited clinical validation remain key barriers to clinical translation. Further preclinical and clinical studies are needed to establish the role of EVs in liquid biopsy and personalized targeted therapy for TC. This review provides a comprehensive and systematic overview of EVs in TC, with particular emphasis on methodological factors influencing EV research, including sample-specific isolation and characterization strategies.

Luteolin (LUT) is a poorly water-soluble natural anti-angiogenic agent. To address this limitation, we develop an ion- and pH-responsive in situ gel system (LUT-NLC-ISG) by incorporating LUT-loaded nanostructured lipid carriers (LUT-NLC) into a gellan gum/Carbopol matrix, aiming to enhance ocular bioavailability and therapeutic efficacy against CNV. Methods: LUT-NLC-ISG was optimized using a central composite design-response surface methodology (CCD-RSM) and characterized by physicochemical properties (particle size, viscosity, gelation behavior). Ocular pharmacokinetics and biodistribution were evaluated in rabbits after a single topical administration. Biocompatibility was assessed via Hen's egg test-chorioallantoic membrane assay (HET-CAM), Draize tests, and cytotoxicity studies. Therapeutic efficacy and mechanism were investigated in a murine model of alkali burn-induced CNV. Results: The optimized LUT-NLC-ISG had a particle size of 25.27 \u00b1 0.23 nm and exhibited a 45-fold viscosity increase upon simulated tear fluid (STF) exposure. In rabbits, LUT-NLC-ISG significantly increased the bioavailability of LUT in ocular tissues compared with LUT-NLC alone, with 2.57-, 1.83-, and 10.59-fold higher area under the concentration-time curve (AUC) in the cornea, conjunctiva, and tears, respectively and exhibited excellent ocular biocompatibility. In the CNV mouse model, 0.1% (w/v) LUT-NLC-ISG effectively inhibited corneal neovascularization, comparable to 0.025% dexamethasone, and downregulated VEGF-A and MMP-9 expression. Conclusions: LUT-NLC-ISG synergistically combines NLC technology and dual-sensitive in situ gelation to significantly improve LUT ocular bioavailability, offering a promising non-invasive candidate for CNV management.",

Using a reproducible buccal xenograft model with serial time-point and spatial analyses, we aimed to define stage-and region-resolved microenvironmental remodeling during cervical lymph node metastasis. A buccal xenograft model of cervical lymph node metastasis was used, and tumor-draining lymph nodes were analyzed at serial time points using immunofluorescence staining and confocal microscopy. The lymphovascular architecture, stromal remodeling, hypoxia, and immune cell distribution were evaluated during metastatic progression. The model reproducibly induced cervical lymph node metastasis with a gradual temporal progression. Before overt tumor colonization, tumor-draining lymph nodes showed features of a pre-metastatic niche, including expansion of LYVE-1\u207a lymphatic vessels, remodeling of high endothelial venules, and increased recruitment of CD11b\u207a myeloid cells and F4/80\u207a macrophages. Confocal imaging revealed that the tumor cells were initially localized within the subcapsular sinus lymphatic vessels and subsequently expanded into the lymph node parenchyma. During invasive progression, metastatic regions showed progressive loss of CD31\u207a blood vessels and LYVE-1\u207a lymphatic vessels, accompanied by GLUT1 upregulation, fibrinogen deposition, disruption of PDGFR\u03b2\u207a fibroreticular networks, and spatially organized myeloid cell accumulation at the invasive front. This study delineated a stage- and region-resolved sequence of nodal microenvironmental remodeling during HNSCC metastasis, linking premetastatic lymphovascular changes to intralymphatic tumor colonization and subsequent invasive regional remodeling. These findings provide an integrated spatiotemporal framework for understanding the progression of the metastatic lymph node microenvironment."

Ginger-derived nanovesicles exhibit anti-tumor potential [ID: 42207394], suggesting a therapeutic bridge where these vesicles stabilize the HA microenvironment.

The reduction in LVD would likely be substantial, but quantitative clinical figures are missing; modeling in CAM assays or mouse models of node metastasis suggests inhibition efficacy could surpass 50-70% based on observed tumor shrinkage in related modalities."
