RNA sequencing and immunoblotting analyses revealed that peiminine markedly suppresses postischemic inflammation. Correspondingly, peiminine exerts its neuroprotective effect primarily through actions on microglia but not astrocytes, indicated by neuron\u2013glia cocultures and transgenic mice models with targeted cell\u2010type depletion. Biolayer interferometry and molecular dynamics simulations indicated that peiminine selectively binds to AIM2, showing no interaction with NLRP1 (NLR family pyrin domain containing 1) and approximately 100\u2010fold higher affinity compared with NLRP3. Notably, peiminine specifically activates the selective autophagic clearance of AIM2 inflammasomes within microglia without increasing overall autophagic flux or affecting other inflammasomes. Selective blockage of autophagy in microglia abolished the neuroprotective effect of peiminine.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec xml:lang=\"en\">\n
