ABSTRACT Cerebral ischemia/reperfusion injury is one of the main causes neuronal damage. Neuron ferroptosis and microglia polarization are considered as critical processes during cerebral ischemia/reperfusion. Adipocyte enhancer‐binding protein 1 (AEBP1) usually acts a transcriptional repressor which involved in various diseases. However, it still remains unknown whether AEBP1 could have important roles regulating neuron injury. The oxygen‐glucose deprivation reperfusion (OGD/R)‐treated cells middle artery occlusion (MCAO)‐treated mice were used vitro vivo models. differentially expressed factors analyzed according to GEO datasets. Relative mRNA expression levels detected by qRT‐PCR western blot analysis. Cell viability was measured CCK‐8 assay. ROS, GSH iron contents using specifical assay kits. CD26 CD206 immunofluorescence Inflammatory cytokines ELISA. association between PRKCA assessed luciferase reporter ChIP analyses. damage TTC staining neurological deficit score. Transcription factor increased OGD/R‐treated HT22 BV2 cells. silencing attenuated OGD/R‐induced cell through increasing viability, GPX4 levels, decreasing ACSL4 levels. knockdown promoted M2 CD206‐positive Arg‐1 level, reducing iNOS, TNF‐α, IL‐1β IL‐6 transcriptionally repressed expression, further regulated PI3K/Akt signaling activation. Inhibition or reversed effects on polarization. downregulation infarct size scores MCAO‐treated mice. mitigated activating signaling, indicating potentially protective action
