p38 phosphorylation in microglia in Vc. Photomicrographs of pp38-IR cells (a, d, g), Iba1-IR cells (b), pp38-IR and Iba1-IR cells (c), GFAP-IR cells (e), pp38-IR and GFAP-IR cells (f), NeuN-IR cells (h), and pp38-IR and NeuN-IR cells (i) in Vc on day 4 after CFA injection. The arrow denotes double-IR cells. j Relative amount of pp38 protein in Vc on day 4 after CFA or saline injection. p38 protein was used as a loading control. Data represent mean ± SEM; n = 12 in each; ***p < 0.001; compared to saline-injected rats by Student’s t tests.
