My research interest focuses on the physiology of microglia, the innate immune cells in the brain. In particular I am interested in the functional roles of receptors and ion channels of microglia, both in physiology and pathology. Due to their enormous pathological potential my current and future research focuses on the importance of microglia-mediated mechanisms for the pathogenesis of neurodegenerative diseases.
Microglia continuously survey the brain to detect infection or cell damage, remove dying neurons and prune synapses during development. We have recently shown that microglial immune surveillance and interleukin-1β release are regulated by the K+ channel THIK-1.
