It was reported that NLRP3/caspase-1-dependent pyroptosis participated in the cerebral ischemia/reperfusion injury and cognitive decline after focal cortical infarction, NLRP3 inhibitor and caspase-1 inhibitor could improve the symptoms, respectively (Sun et al., 2020; Dong et al., 2022). Here, NLRP3 is linked to brain ischemia.
