Figure Lengend Snippet: PAD4 promotes neuroinflammation and neuronal death via IRE1α/ASK1/JNK signaling pathway after TBI. A Schematic image of adeno-PAD4-EGFP and overexpression of PAD4 in the cortex of the mouse. B , C mNSS test on day 1 ( B ) and days 3 ( C ) post-TBI. **p < 0.01, ***p < 0.001, n = 10 per group. D , E Rotarod test on day 1 ( D ) and days 3 ( E ) post-TBI. *p < 0.05, **p < 0.01, ***p < 0.001, n = 10 per group. F Representative western blot bands and densitometric quantification of Iba-1, CD16, and CD206 in the contused cortex after TBI. *p < 0.05, **p < 0.01, ***p < 0.001, n = 6 per group. G Representative image of the FJC (green) staining and representative images of TUNEL (green) co-localization with neurons (NeuN, red) in the contused cortex at 3 days after TBI. Nuclei were stained with DAPI (blue). Scale bar = 100 μm. H , I Quantitative analysis of FJC-positive cells ( H ) and quantitative analysis of TUNEL-positive neurons ( I ) in the contused cortex at 3 days after TBI. *p < 0.05, **p < 0.01, n = 6 per group. J Representative western blot bands and densitometric quantification of pIRE1α, pASK1, and pJNK in the contused cortex after TBI. *p < 0.05, **p < 0.01, ***p < 0.001, n = 6 per group
