Figure Lengend Snippet: FSH induces neuroinflammation in mice. Four weeks after the FSH treatment, the brain and serum of the mice were harvested for western blot (a,b), Elisa assay (c), and immunofluorescence staining (d,e). (a) Representative immunoblots showing the protein expression of IL-1β and IL-6 in the hippocampus. (b) Quantification of the immunoreactivity of IL-1β and IL-6 protein expression, data are shown as represent mean ± SEM, n = 4 mice per group. (c) ELISA quantification shows the levels of proinflammation factors IL-1β, IL-6, and TNFα in the serum, data are shown as mean ± SEM, n = 6 mice per group. (d) Immunofluorescent co-staining of Iba1 (gray) and GFAP (red) on the hippocampal sections (scale bar: 150 μm). (e) Quantification of Iba1 positive and GFAP positive cells, data represent mean ± SEM ( n = 4 mice per group, 10 sections each mouse). Statistical analysis was performed by one-way ANOVA followed by Tukey’s multiple comparisons test. *p < 0.05, * *p < 0.01; ns, not significant.
