Abstract

We report the detailed expression profile of TRPM2 mRNA within the human central nervous system (CNS) and demonstrate increased TRPM2 mRNA expression at 1 and 4 weeks following ischemic injury in the rat transient middle cerebral artery occlusion (tMCAO) stroke model. Microglial cells play a key role in pathology produced following ischemic injury in the CNS and possess TRPM2, which may contribute to stroke-related pathological responses. We show that TRPM2 mRNA is present in the human C13 microglial cell line and is reduced by antisense treatment. Activation of C13 cells by interleukin-1β leads to a fivefold increase of TRPM2 mRNA demonstrating transcriptional regulation
