Cortical neuronal cell death following traumatic brain injury (TBI) evoked by the cortical impact is a significant factor that contributes to neurological deficits. In the current study, we harvested the injured area and perilesional area of the injured brain induced by TBI. We explored the functions of Sec22b, an apoptosis-promoting kinase, and a pivotal bridge builder of apoptotic signaling in the etiopathogenesis of an experimental rat model of TBI. We found that Sec22b was expressed in neurons in the injured cortical area, and the expression level significantly decreased after TBI, especially at 24 h. Administration of Sec22b overexpressed plasmid signiï¬cantly ameliorated TBI-induced apoptosis, neurological deï¬cits, and blood-brain barrier permeability, accompanied by the activation of autophagy. However, the administration of Sec22b knockdown resulted in the opposite eï¬ ;ects. Altogether, these findings indicated that Sec22b plays a neuroprotective role after TBI, suggesting that Sec22b may be a potential therapeutic target for TBI. We speculated that this neuroprotective effect might be achieved by upregulating autophagy levels and required further studies to explore.
