Figure 5. Effects of maternal and offspring diet on Iba-1 expression in rat brain.

Male rats were segregated into CD/CD, CD/HFD, HFD/CD and HFD/HFD groups as described in Methods, and the effects of maternal and offspring diet on expression of the microglia marker Iba-1 was evaluated by immunocytochemistry and Western blot as described in Methods. (A) The levels of Iba-1 protein measured by Western blot. Data are means and SEM, with 9-10 individual rats per group, and ANOVA indicated an overall significant effect of Offspring diet on Iba-1 expression in the cortex (text insert). (B) Representative low-magnification and high-magnification (insert) images depict the pattern of Iba-1 staining in cortex as observed in sections taken at the level of the lateral ventricle.
