Mesenchymal stem cell-derived exosomal microRNA-367-3p alleviates experimental autoimmune encephalomyelitis via inhibition of microglial ferroptosis by targeting EZH2.

Multiple sclerosis (MS) is an autoimmune, inflammatory demyelinating disorder of the central nervous system. Accumulating evidence has underscored the therapeutic potential of bone marrow mesenchymal stem cells (BMSCs)-derived exosomes (BMSC-Exos) containing bioactive compounds in MS. Herein, the current study sought to characterize the mechanism of BMSC-Exos harboring miR-367-3p both in BV2 microglia by Erastin-induced ferroptosis and in experimental autoimmune encephalomyelitis (EAE), a typical animal model of MS.

Exosomal miR-23b-3p from bone mesenchymal stem cells alleviates experimental autoimmune encephalomyelitis by inhibiting microglial pyroptosis.

Multiple sclerosis (MS) is a chronic autoimmune disease that affects the central nervous system and is marked by inflammation and damage to the myelin sheath surrounding nerve fibers. Recent studies have highlighted the therapeutic value of exosomes (Exos) obtained from bone marrow mesenchymal stem cells (BMSCs) in MS treatment. These BMSC-Exos contain biologically active molecules that show promising results in preclinical evaluations.

Altered non-coding RNA profiles and potential disease marker identification in peripheral blood mononuclear cells of patients with NMOSD.

Neuromyelitis optica spectrum disorder (NMOSD) is an inflammatory demyelination disorder, and dysregulation of RNAs contributes to its pathogenesis. We aimed to reveal the expression profiles of RNAs, including messenger RNA (mRNA), circular RNA (circRNA) and long non-coding RNA (lncRNA), in the peripheral blood mononuclear cells (PBMCs) of patients with NMOSD. Seven NMOSD patients and seven healthy controls (HCs) were enrolled in the competitive endogenous RNA (ceRNA) microarray analysis.
