Abstract Background Exosomes, as extracellular membrane vesicles, play important roles in intercellular communication and can influence tumour progression. Circular RNAs (circRNAs) have been reported various malignancies are also components of exosomes. However, the role exosomal circRNAs gastric cancer (GC) progression has not completely clarified. Methods The enriched GC were identified using circRNA sequencing. biological function circMAN1A2 was investigated a series vitro vivo experiments. PKH-67 staining used to label molecular mechanism via mass spectrometry, immunoprecipitation, Western blot, single-cell RNA-sequencing data analyses. Results In our study, we determined that (hsa_circ_0000118) GC-derived Higher expression related poor survival patients (HR = 2.917, p 0.0120). Exosomal promoted suppressed antitumour activity T cells. Moreover, bound SFPQ cells cells, promoting G1/S phase transition cell cycle while inhibiting activation receptor signalling pathway decrease activity. Mechanistically, competed with FBXW11 for binding SFPQ, preventing FBXW11-mediated k48-linked ubiquitination protein degradation, thereby stabilizing expression. Conclusions Our work confirms critical immunosuppression GC. This novel axis circMAN1A2-SFPQ provides new insights into circRNA-based diagnostic therapeutic strategies.

Extracellular vesicles (EVs) hold promise for tissue regeneration, but their low yield and limited therapeutic efficacy hinder clinical translation. Bioreactors provide a larger culture surface area stable environment large-scale EV production, yet ability to enhance is limited. Physical stimulation, by inducing cell differentiation modulating cargo composition, offers more efficient, cost-effective, reproducible approach compared the loading of EVs biochemical priming parental cells. Herein, effects 3D-printed perfusion bioreactor with topographical cue on macrophage bioactivity were assessed. The results indicate that increased 12.5-fold enhanced in promoting osteogenic angiogenesis via upregulated miR-210-3p. Mechanistically, fluid shear stress activates Piezo1, triggering Ca2+ influx Yes-associated protein (YAP) nuclear translocation, secretion enhancing M2 polarization conjunction morphological changes guided aligned topography. Moreover, porous electrospun membrane-hydrogel composite scaffold loaded bioreactor-derived exhibited outstanding rat cranial defect model. This study presents scalable, platform production EVs, potentially overcoming key challenges translating EV-based therapies clinic.

Abstract Exosomes, small extracellular vesicles with lipid bilayer membranes, play a crucial role in cellular communication and can transfer diverse biological cargo, including proteins, lipids, nucleic acids, from donor to recipient cells. Exosomes possess immunological properties, such as antigen delivery immune activation, along excellent drug capabilities, making them promising candidates for vaccine development. For different diseases, exosome‐based vaccines be designed therapeutic or prophylactic by leveraging immunity humoral immunity. With the emergence of precision medicine, personalized demonstrate exceptional potential. This review systematically introduces sources, biogenesis mechanisms, components exosomes describes their regulatory roles system. Subsequently, preparation, administration, therapy are discussed. Finally, applications clinical trials fields anti‐infection anti‐tumor therapies particularly highlighted, an analysis potential challenges future

Extracellular vesicles (EVs), which are secreted by various cell types, hold significant potential for cancer therapy. However, there several challenges and difficulties that limit their application in clinical settings. This review, integrates the work of our team recent advancements this research field, discusses EV-based treatment strategies to guide application. The following discussed: 1) leveraging inherent properties EVs development treatments; 2) modifying using EV engineering methods improve drug loading delivery; 3) targeting key molecules tumor-derived (TDE) synthesis inhibit production; 4) clearing TDEs from tumor microenvironment. Additionally, on basis into vaccines bispecific antibodies, review elaborates enhance antitumor immunity via modifications can ability stability progress AI technology targeted delivery drugs. Although limited enhancing abilities, provides an in-depth discussion prior studies. Finally, summarizes use therapy highlights need be addressed.

Summary Background Cutaneous leishmaniasis (CL) is characterized by immune dysregulation that facilitates chronic infection. Objective To investigate the role of T cells in immunopathology CL characterizing landscape skin lesions using single-cell RNA sequencing (scRNA-seq). Methods We performed scRNA-seq to profile from PBMC and patients. Results analyzed transcriptional distinct populations CD4+ CD8+ migratory lesions. resident displayed expression exhaustion markers were categorized into progenitor, transitional, terminal stages, with HAVCR2 (TIM-3) identified as a potential driver dysfunction. Compared psoriasis healthy skin, showed reduced frequency regulatory (Tregs), potentially linked oxidative stress, DNA damage, increased apoptosis. also detected double-negative (DN) γδ cells, suggesting their antigen presentation via MHC class II through TGF-β signaling. Conclusion This study provides novel insights evasion mechanisms CL, identifying TIM-3, Treg modulation, functional DN targets for future immunotherapies.
