A single blast overpressure (BOP) caused increased tau phosphorylation in the mouse brain. (A) Representative Western blots demonstrated the early elevation of phospho-tau (Ser202/Thr205 detected by AT8, pS262, and Ser396/Ser404 detected by PHF1 antibody and pathological conformation changes of tau (Alz50) in the cortex after blast (n = 5/group). Tau-5 was probed to detect total tau. (B–E) Quantification analysis of AT8 (B), Alz50 (C), pS262 (D), and PHF1 (E) normalized to total tau detected b they tau 5 antibody. (Data are means ± SEM, * p < 0.05, ** p < 0.01; ns, non-significant). TBI: traumatic brain injury.
