Caspases in immunity & inflammation
My laboratory is broadly interested in understanding the mechanisms of inflammasome signalling. Inflammasomes are molecular complexes that assemble in response to microbe- or danger-signal and activate caspase-1. Other inflammatory caspases, such as caspase-4, -5 (both together represented by a single caspase-11 in the mouse) and caspase-8, also regulate these pathways. My group is interested in these caspases and their contribution to health and disease.
We are studying new cell-intrinsic roles of caspases in inflammation and immunity. See Research Highlights to see our recent work, which was on the cover of Science Signaling.
