  • Title: MicroRNA-155 modulates Th1 and Th17 cell differentiation and is associated with multiple sclerosis and experimental autoimmune encephalomyelitis.

    Journal: J Neuroimmunol; 2014 Jan 15; 266(1-2):56-63. PubMed ID: 24332164.
    Abstract:
    Mammalian noncoding microRNAs (miRNAs) are suggested to be involved in immune system function. We found that miR-155 expression was highly correlated with disease severity in patients with multiple sclerosis and mice with experimental autoimmune encephalomyelitis (EAE). Knockdown of miR-155 resulted in low Th1 and Th17 cells and mild EAE, and its overexpression led to more Th1 and Th17 cells and severe EAE. MiR-155 promoted the development of inflammatory Th17/Th1 cell subsets. These findings demonstrate that miR-155 confers susceptibility to EAE by affecting inflammatory T cell responses and can be a new target for therapy of multiple sclerosis.
