Mechanistic investigations revealed that TGF-β3 is a direct target of miR-140-3p, and is involved in the miR-140-3p-mediated effects on neonatal repetitive pain and neuroinflammation.
Because exosomal miR-140-3p is considered to have an inflammation-associated biological function in airway smooth muscle cells and targets Myomarker muscle-specific transmembrane protein, it appears that its overexpression in circulating exosomal miR-140-3p may have some role in the mechanism underlying self-limited musculoskeletal pain.
