Active NLRP3 inflammasome, which cleaves the pro-inflammatory cytokines IL-1β to its active form [15], has been detected in astrocytes in several animal models of intracerebral hemorrhage, such as ischemia/reperfusion injury and hemorrhage transgenic amyotrophic lateral sclerosis [16–19]. This evidence concerns the gene NLRP3 and intracerebral hemorrhage.
