“…A great deal of miRNAs enveloped into MSC exosomes, such as miR-1-3p, miR-22-3p, miR-25, miR-26a, miR-26b-5p, miR-31, miR-126, miR-132, miR-138-5p, miR-146a-5p, miR-206, miR-223-3p, and miR-542-3p, were demonstrated to improve neuronal, astrocytic, oligodendrocytic, and microglial survival by downregulating target genes including KDM6B, p53, KLF9, CH25H, TRAF6, ACVR2B, LCN2, TLR4, RMRP, or CysLT2R. 38 , 76 , 77 , 78 , 79 , 80 , 81 , 82 , 83 , 84 , 85 , 86 , 87 Autophagy is also associated with the promotion of cell death via leading to cellular accumulation of toxic metabolites or cellular self-degradation. 88 Exosomal transfer of miRNAs from MSCs can reduce cell death by inhibiting excessive autophagy.…”
