Activation of STING can aggravate pyroptosis by up-regulating IRF7 and P-IRF3. A–D Ana-1 cells were transfected with 10 ug/ml 2′,3′-cGAMP or 5 ug/mL poly(dA:dT) for 6 h before stimulation with LPS and nigericin sodium salt. Western blot of STING, P-STING, IRF7, IRF3, P-IRF3, and NLRP3 (A, B). Pyroptosis of Ana-1 cells was measured by flow cytometry (C, D)
