ABSTRACT
Aim To investigate whether RvDl regulates microglial polarization through FPR2 and alleviates the inflammatory damage after cerebral ischemiareperfusion. Methods The middle cerebral artery occlusion (MCAO) model was established by Longa method. The rats after MCAO were randomly divided into; model group, RvD1 group and RvD1 + Boc-2 group, and a sham-operated group was set up as control as well. Cerebral infarct volume was measured, MPO activities in rat brain were measured by immunofluorescence. The expression and localization of FPR2/Iba-1, CD16/Iba-1 and CD206/Iba-1 were detected by immunofluorescence double labeling method. The expressions of TNF-α, IL-1β and iNOS in M1 and TGF-β, IL-10, Arg-1 in M2 were detected by RT-qPCR. Results RvDl significantly reduced cerebral infarction volume and the expression of MPO, and its receptor FPR2 was expressed in microglia. RvD1 down-regulated M1 markers CD16
