Fig. 7: Effects of CAP and Nic on microglia in the striatum and substantia nigra of MPTP-induced mice.

a Representative immunofluorescence images of Iba1 and CD68 in the striatum; b Representative immunofluorescence images of Iba1 and CD68 in the substantia nigra; c Iba1 positive cells in the striatum; d Iba1 and CD68 co-localization in the striatum; e Iba1 endpoints in the striatum; f Iba1 process length in the striatum; g Iba1 positive cells in the substantia nigra; h Iba1 and CD68 co-localization in the substantia nigra; i Iba1 endpoints in the substantia nigra; j Iba1 process length in the substantia nigra. Iba1: green; CD68: red; DAPI: blue; Images were captured using a 63× objective, scale bar = 25 μm; enlarge scale bar = 2.5 μm. (n = 6 mice per group for a–j). Statistical analyses were performed by one-way ANOVA followed by Tukey’s multiple comparison test. *p < 0.05, **p < 0.01, ***p < 0.001.
