Figure Lengend Snippet: (A) Schematic diagram of the visual pathway and key observation areas in its intracranial segment. (B) Representative images of immunofluorescence staining for NeuN (green) and NLRP3 (red), Iba-1 (grey) in mouse visual cortex slices, Group information is shown in images. The red triangle marks indicate the co-localization of NLRP3 and NeuN. The scale bars for all fluorescence intensity channels and the merge are set at 50 μm, the magnified inset is 20μm. Quantitative analysis of visual cortex immunofluorescence density in Iba-1 (C) and NLRP3 (G) . (H) Fluorescence intensity of NeuN + NLRP3 + / NeuN + , n = 4. (D, E, F, I, J) Western blot analysis of Iba-1, IL-1β, cleaved Gasdermin D and NLRP3 in visual cortex lysates, the molecular mass is indicated in kilodaltons, n = 3. (K-L) Quantitative analysis of representative fluorescence images of NeuN staining with TUNEL labeling in the peri-contusion region from different groups that information is shown in images, Scale bar = 100 μm, n = 4. (M) Quantitative analysis of visual cortex NeuN + cells, n = 4. Error bars indicate mean ± SD. * p < 0.05, ** p < 0.01, *** p < 0.001, ns p > 0.05.

Article Snippet: Brain sections were subjected to double staining using NeuN antibody and the terminal deoxynucleotidyl transferase-mediated dUTP nick end labeling (TUNEL) assay kit (Beyotime, #C1090) to identify DNA damage, following the manufacturer’s protocol.
