cAMP elevating agent Forskolin increases Treg function via the increase of cAMP. As proof of principle we tried to restore Treg function after miR-142-3p overexpression using cAMP elevating agent Forskolin. 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). Upon treatment with Forskolin, cAMP levels increased significantly (B). Moreover, forskolin treatment tended to restore suppressive function in miR-142-3p overexpressed MTregs (C).*p = 0.05–0.01, **p = 0.01–0.001.
