Figure 8. c-Jun N-terminal kinase (JNK) and nuclear factor-κB (NF-κB) are involved in RIPK1-mediated inflammation. (A, B) Expression levels of p-JNK, p-IKBα, and p-P65 in chondrocytes. The experiments were repeated three times independently. Columns represent means ± SD. *p < 0.05, **p < 0.01, ***p < 0.001, ****p < 0.0001. © Schematic of the TIR-domain-containing adapter-inducing interferon b (TRIF)/MYD88-RIPK1-tumor necrosis factor receptor-associated factor 2 (TRAF2) feedback loop and activation of the NF-κB and JNK signaling pathways in OA.
