Fig. 10. Effect of M. vaccae on IL4 mRNA and protein expression in subregions of the hippocampus.
Animals received 3 injections of either vehicle or M. vaccae (0.1 mg, s.c.). Eight d after the third injection, (A) IL4 mRNA expression and (B) IL4 protein levels were measured in dorsal, intermediate, and ventral hippocampus. Data are presented as the mean + s.e.m. N = 8 animals per experimental group. Significant main effect of M. vaccae compared to vehicle, * p < 0.05.
