Summary: This study explores the mechanism of tumor-associated microglia/macrophages (TAMs) activation/polarization in sonic hedgehog subgroup medulloblastoma (SHH-MB). M2-like macrophages were found to be enriched in SHH-MBs, and their polarization can be induced by SHH MB-derived exosomes. Downregulated let-7i-5p and miR-221-3p were identified as regulators of TAM polarization via upregulating peroxisome proliferator activated receptor gamma (PPAR gamma). The PPAR gamma antagonist improved the antitumor activity of SMO inhibitor by inhibiting M2-like TAMs. These findings suggest a potential immunotherapeutic strategy for SHH-MB.

Summary: This study revealed that high levels of plasma exosomal miR-136-5p are associated with poor clinical response to anlotinib. Anlotinib-resistant NSCLC cells transfer functional miR-136-5p to parental NSCLC cells via exosomes, promoting cell proliferation. Furthermore, miR-136-5p confers anlotinib resistance by targeting PPP2R2A and activating the Akt pathway.

Summary: Pancreatic cancer (PC) is highly aggressive with a poor prognosis. The tumor microenvironment (TME) of PC is complex and diverse. Various cellular components in the microenvironment secrete different substances that promote tumor development. These substances can be released via exosomes, which are abundant extracellular vesicles (EVs) capable of carrying factors and enabling intercellular communication. MiRNAs are involved in regulating pathological and physiological processes and can be transported by exosomes to regulate the TME. Exosomal miRNAs hold promise as future targets for PC diagnosis and prognosis, offering potential new treatment strategies.

Summary: In this study, exosomes from cooked meat were extracted using ultra-high-speed centrifugation, with approximately 80% of the vesicles falling within the range of 20-200 nm. Flow cytometry was used to evaluate the surface biomarkers of the isolated exosomes. Different microRNA profiles were observed in exosomes derived from cooked porcine muscle, fat, and liver. The chronic administration of cooked pork-derived exosomes to mice resulted in increased levels of miR-1, miR-133a-3p, miR-206, and miR-99a in the plasma. The study also revealed abnormal glucose metabolism, insulin resistance, and increased lipid droplets in the mice's liver, indicating that microRNAs from cooked pork may play a critical role in regulating metabolic disorders.

This review examines the impact of smoking on immune regulation, placental function, and vascular development. The study aims to understand how maternal smoking affects placental function in both normal and pathological pregnancies. Smoking cessation is recommended for future mothers as the components of tobacco smoke can have detrimental effects on placental function.

Summary: Extracellular vesicles, specifically small EVs, are involved in neuroinflammation and neurodegenerative diseases. Aging brains show increased neuroinflammation and glial activation, which can be influenced by EVs. Our study demonstrates that sEVs from aged mice can cross the blood-brain barrier and induce glial cell activation in young animals.

Summary: The concept of biological identity has been a central issue in immunology. The expanded immunotolerance observed in pregnancy challenges the assumption that foreign entities should be rejected by the immune system. Microchimeric cells play a crucial role in enhancing immune tolerance and genetic fitness during pregnancy, but they may also cause abnormal immune activation. Studies have revealed a synergistic effect between microchimerism and cellular communication through extracellular vesicles (EVs), which participate in feto-maternal tolerance and antigen presentation. This review discusses the current understanding of microchimerism and the potential role of EVs in mediating allorecognition and tropism of microchimeric cells during human pregnancy.

Summary: The study reveals the role of miRNAs in regulating endoplasmic reticulum stress and unfolded protein response in decidualized cells and endometrium associated with reproductive failures. The findings highlight the potential involvement of miR-17-5p, miR-21-5p, and miR-193b-3p in the regulation of ERS/UPR pathways and inflammation during embryo implantation. The expression of these miRNAs differs in stromal cells from patients with recurrent pregnancy loss and recurrent implantation failure, suggesting alterations in the regulation of ERS/UPR pathways.
