Neutrophils accumulate in the hippocampus and contribute to the progression of SAE. (A and B) Representative immunoblots and quantification of Ly6G levels in the hippocampus at 24 hours after operation. (C and D) Representative FACS plots and quantification of neutrophils (Ly6G+CD11b+) measured by flow cytometry in blood at 24 hours after operation. (E and F) Freezing to context and freezing to tone examined at 24 hours after operation. (G) The BBB permeability of hippocampus evaluated by Evans blue extravasation at 24 hours after operation. (H) Representative TUNEL (green) and DAPI (blue) immunofluorescence staining in the hippocampus. Scale bar indicates 20 μm. Higher magnification images are shown at the right row of figures-scale bar indicates 10 μm. (I) The quantitative results of the percentage of TUNEL-positive area in the total area of the image (whole microscopic field) in the hippocampus. (J) Representative IBA-1 (red) and DAPI (blue) immunofluorescence staining in the hippocampus. Scale bar indicates 20 μm. Higher magnification images are shown at the right row of figures-scale bar indicates 10 μm. (K) The quantitative results of the percentage of IBA-1 positive area in the total area of the image (whole microscopic field) in the hippocampus. The values are presented as mean ± SD (n=6 for Fig. B, D, G, I and K; n=8 for Fig. E and F; **P<0.01, ***P<0.001, ****P<0.0001, ns=not significant, one-way analysis of variance).
