Immunofluorescence staining of hippocampal sections in each group rats (α7nAchR) (n = 3, per group). Compared with control group and taVNS group, representative confocal images of brain sections show less expression of α7nAchR (green) in model group. The microglia transform from ramified morphology (control group) to ameboid form (model group) to ramified state (taVNS group). Compared with control group and taVNS group, the co-expression between α7nAchR (green) and microglia (red) decreased in model group. α7nAchR (green), Iba-1 (red), DAPI (blue), Merge (yellow); 40 times objective lens, scale bar: 100 μm and 20 μm magnification
