CXCR3 inhibition blocks NF-κB signaling pathway activation by promoting autophagy in the IPEC-J2 cells. The cells were divided into four groups, namely, the Control group, LPS (10 μg/mL) group, LPS + AMG487 (1 μM) group, and LPS + AMG487 + 3-MA (5 mM) group. The cells were treated for 12 h, and the protein was extracted for Western Blot. (A) The expression of NF-κB pathway-related proteins in IPEC-J2 cells. (A,B) TNF-α expression. (A,C) IL-6 expression. (A,D) p-p65/p65 expression. (A,E) JNK1 expression. (A,F) p-JNK1/JNK1 expression. Image J software analyzed the optical density values of NF-κB signaling pathway-related proteins. Values represent the mean ± SEM. of three independent experiments. Significant differences are represented by * p < 0.05, ** p < 0.01, and ns (not significant).
