Acute brain injuries (ABI) caused by various emergencies can lead to structural and functional damage tissue. Common causes include traumatic injury, cerebral hemorrhage, ischemic stroke, heat stroke. Globally, ABI represent a significant portion of neurosurgical cases. Previous studies have emphasized the therapeutic potential stem cell-derived extracellular vesicles (EVs). Recent research indicates that EVs extracted from resident cells in central nervous system (CNS) also show following injury. Microglia, as innate immune CNS, respond changes internal environment altering their phenotype secreting impact CNS cells, including neurons, astrocytes, oligodendrocytes, endothelial neural (NSCs), microglia themselves. Notably, under different external stimuli, either promote neuronal survival, angiogenesis, myelin regeneration while reducing glial scarring inflammation, or they exert opposite effects. This review summarizes evaluates current findings on how microglia-derived influence after stimuli. It analyzes interaction mechanisms between discusses future directions clinical applications.

Ischemic stroke is a prevalent form of cerebrovascular accident, with its pathogenesis involving the intricate interplay between neuroinflammation and energy metabolism. Cerebral ischemia disrupts oxygen supply, triggering metabolic dysregulation activating neuroinflammatory responses, ultimately resulting in cellular damage. This review provides an exhaustive analysis complex mechanisms ischemic stroke, particular focus on interaction The interruption supply due to cerebral initiates activates including release inflammatory cytokines activation immune cells, contributing damage further disturbances. Studies indicate that metabolism significantly impairs neural cell function interacts neuroinflammation, exacerbating brain injury. Therapeutic strategies primarily concentrate modulating suppressing emphasizing importance in-depth research into their provide theoretical foundation for new treatment stroke. Future should how balance anti-inflammatory regulation minimize promote recovery.

Background Esophageal cancer (EC) is a common malignant tumor of the digestive tract and an important health-related problem in many developing countries. squamous cell carcinoma (ESCC) most subtype EC. The cancer-associated fibroblasts (CAFs) are major stromal cells ESCC microenvironment. They play role proliferation, metastasis, angiogenesis chemotherapy resistance through paracrine processes. However, roles circRNAs enriched CAF-derived exosmes have not been reported. Objective To explore mechanisms how CAF affects proliferation metastasis processes to investigate exosomes. Methods Exosomes were isolated from conditional medium using differential ultracentrifugation, then validated by Nanosight analysis. Exosome secretion inhibitor-GW4869 validates pro-carcinogenic qRT-PCR showed highest expression circ_0076535 exosomal CircRNA, knockdown it confirmed its function. Online bioinformatics tool was utilized predict potential target gene circ_0076535, captured miR-145-5p as with high predictive value. targeting association between further dual luciferase reporter experiment. stimulation tumour development EMT exosome vivo. Results In our research, we found that exosomes increased migration, invasion cells. Circ_0076535 highly CAF-exosomes transferred into directly depend on internalization CAF-exosomal level induced EMT. Mechanistic experiments revealed acted sponge absorb activated NF-κB signaling pathway. Conclusions Conclusively, promoted progression via miR-145-5p/NF-κB axis expected be biomarker for early diagnosis treatment ESCC.
