Figure 4: Effects of FA on the expression of p-JNK and inflammatory cytokines in the mouse PFC. (A) Representative bands of p-JNK and JNK are shown. (B) Relative ratio of p-JNK/JNK. (C) Representative bands of TNF-α and IL-1 β are shown. (D) Optical density (O.D.) of TNF-α. (E) O.D. of IL-1 β (mean ± SD, n = 6). aP < 0.05 vs. the control group; bP < 0.05 vs. the LPS group; cP < 0.05 vs. the LPS + FA group. LPS: lipopolysaccharide; SP: SP600125; FA: ferulic acid; Ani: anisomycin.
