Pyroptosis is a highly specific type of inflammatory programmed cell death that different from necrosis or apoptosis. It is initiated by cellular detection of acute damage via recognizing pathogen-associated molecular patterns (PAMPs) by NOD-like receptors (NLRs) or AIM2-like receptor (AIM2). NLRs and AIM2 could trigger the formation of a multi-protein complex, known as inflammasome. ⋯ These effects contributed to improving the neurological outcome of CCI mice. In conclusion, NLRs and AIM2 inflammasome-mediated pyroptosis could aggravate BBB damage after TBI. Targeting and controlling pyroptosis in injured BBB would be a promising therapeutic strategy for TBI in the future.
