IL17A and myeloid sarcoma: In order to evaluate the association between the regulation of different miRNAs with cytokines expression in PBMCs of MS patients and HDs, we measured expression levels of IL-17a, IFN γ, TNFα and IL-6 mRNA in the MS group that overexpressed miR-155/miR-132 and in the MS patients with demonstrated up-regulation of miR-26a compared to HD.
