A strong therapeutic target of ischemic stroke is controlling brain inflammation. Recent studies have implicated the critical role of C-C chemokine receptor 5 (CCR5) in neuroinflammation during ischemic stroke. It has been reported that the expression of the matrix metalloproteinases, MMP-3, MMP-12, and MMP-13, is controlled by CCR5; however, their expressional regulation in the infarct brain has not been clearly understood. This study investigated the mRNA expression of Mmp-3, -12, and -13 in the ischemic cerebral cortex of photothrombosis mouse model. The three Mmps were highly upregulated in the early stages of ischemic stroke and were expressed in different types of cells. Mmp-3 and Mmp-13 were expressed in blood vessel endothelial cells after ischemia-induction, whereas Mmp-12 was expressed in activated microglia. The expression of Mmp-13 in resting microglia and in neurons of uninjured cerebral cortex was lost in the infarct region. Therefore, the MMPs responding to CCR5 are differentially regulated during ischemic stroke.
