Representative immunofluorescence images for GFAP (green) (A), Iba1 (green) (B), 11β-HSD1 (red) (A and B), nucleus (DAPI, blue) (A and B), and merged in the hippocampal CA1 and CA3 subfields and DG (A and B).

<p>These images confirmed the localization of astrocytes (GFAP-positive cells), microglial cells (Iba1-positive cells), 11β-HSD1, and nuclei. Arrows indicate astrocytes (A) or microglial cells (B) having 11β-HSD1. Scale bars, 50 µm.
