Combination treatment ameliorates pyroptosis in podocytes in vitro. (A) Pyroptotic features were exhibited in cultured primary podocytes after incubated with LPS+ATP, and pretreated with combination treatment. Arrows indicated cells exhibiting pyroptotic-like features. (B) Supernatants from challenged cells were analyzed for cell death, as measured by LDH secretion. (C) Supernatants from the challenged cells were analyzed for IL-1β release. (D) Immunoblotting analysis of NLRP3, caspase-1, GSDMD-NT and ASC expression after tacrolimus, MMF, prednisone or combination treatment after NLRP3 inflammasome activation. * p < 0.05; ** p < 0.01; *** p < 0.001; **** p < 0.0001. LDH, lactate dehydrogenase; DSMO, Dimethyl sulfoxide, FK506, tacrolimus; MMF, mycophenolate mofetil; PNS, prednisone; COM, combination therapy; ASC, apoptosis-associated speck like protein.
