Overexpression of miR-142-3p reduces the suppressive capacity of MTregs in vitro. MTregs were transfected with scrambled (SCR) or miR-142-3p mimic (MIM-142-3p). Live MTregs were sorted and cocultured with responder T (TRESP) cells; after 48 h of stimulation, TRESP cell proliferation was determined (A,B). Transfection with MIM-142-3p significantly increased miR-142-3p levels (C) and reduced the suppressive capacity of MTregs (D). miR-142-3p levels correlated negatively with the suppressive capacity (E). Transfection with MIM-142-3p further decreased ADCY9 mRNA levels (F) and correlated negatively with miR-142-3p levels (G). Additionally, cAMP levels were significantly lower in MIM-142-3p-transfected MTregs (red) than in SCR-transfected MTregs (black) (H). *p = 0.05–0.01.
