IL-17A Abs inhibited the hippocampal TNF-α and IL-6 expression induced by LPS. TNF-α and IL-6 protein expression in serum (a) and in the hippocampus (b) were determined by ELISA. The data are presented as the mean ± s.e.m. (n = 6 in a and b). **P < 0.01 versus control group, ^## P < 0.01 versus LPS treatment group
