Fig. 2From: Inhibition of Nrf2/HO-1 signaling leads to increased activation of the NLRP3 inflammasome in osteoarthritisImmunohistochemistry analysis of the synovium of OA patients. Representative images are shown. a H&E and IHC staining of the synovium in the knee joints. Scale bar = 100 μm. b Relative expression level of NLRP3. c Relative expression level of ASC. d Relative expression level of Nrf2. e Relative expression level of HO-1 (*P < 0.05, **P < 0.01 vs CTL)Back to article page
