Combined Training Improves the Expression Profile of Inflammation-associated Antimicrobial Peptides, MicroRNAs, and TLR-4 in Patients with Multiple Sclerosis.

Some antimicrobial peptides (AMPs), microRNAs (miRs), and Toll-like receptor 4 (TLR-4) are involved in autoimmune diseases, which may be affected by exercise training. The purpose of this study was to investigate the effect of an eight-week combined exercise training (aerobic and resistance) on the expression of inflammatory factors, including, human beta-defensin-2 (hBD-2), cathelicidin (LL-37), TLR-4, miR-23b, miR-155, and miR-326 in women with relapsing and remitting multiple sclerosis (RRMS), which has not been investigated yet. Twenty-three women (20-40 years) with RRMS were randomized into the combined training (CT) and control (CON) groups.
