Research Abstract |
Microglia are intrinsic immune cells in the brain. In response to neurodegenerative diseases, excessively activated microglia change their shapes and release various cytokines involved in the pathogenesis of CNS disease. This study focused on TRPV4 channel expressed in microglia. In vitro and in vivo experiments demonstrate that the depolarization in response to the opening of TRPV4 channel attenuates the driving force for extracellular Ca2+ and suppresses microglial activation.
