Effect of MCH on microglia activation in the hippocampus and cortex of IAV-infected mice. (A) Representative immunofluorescence staining in the hippocampus and cortex of IAV-infected mice Magnification: 200×, bar = 50 μm, MCH-L, MCH low dose + H7N7, MCH-H, MCH high dose + H7N7. (B-C) The numbers of Iba-1+ cells in the hippocampus and cortex. Data were expressed as mean ± SEM, n = 6, 5 slices for each mouse. *P < 0.05, **P < 0.01, ***P < 0.001
