Fig. 3From: Nrf2/HO-1 signaling activation alleviates cigarette smoke-induced inflammation in chronic obstructive pulmonary disease by suppressing NLRP3-mediated pyroptosisThe activated Nrf2/HO-1 pathway suppressed the pyroptosis in lung tissues of COPD mice. A IHC staining of the lung tissues revealed that the activated Nrf2/HO-1 pathway suppressed NLRP3 expression in COPD mice. B Western blot illustrated that the activated Nrf2/HO-1 pathway reduced the expression of pyroptosis-related proteins (Caspase-1 and GSDMD-N) in lung tissues of COPD mice. ***P < 0.001 vs. Control group. # P < 0.05 and ## P < 0.01 vs. COPD groupBack to article page
