Meanwhile, the co-expression of the M2 marker CD206 and Iba1 was higher in the MCAO+OEA group compared with the MCAO + vehicle group (Figure 2B), suggesting that OEA promotes the migration or infiltration of M2-like microglia/macrophages into the infarct border after cerebral ischemia. The gene discussed is MRC1; the disease is brain ischemia.
