Abstract
The identity of most pyroptosis-dependent proinflammatory and potentially regulatory factors and their effects on surrounding cells is poorly understood. The project will study the molecular details and functional consequences of pyroptosis-dependent secreted factors and the mechanisms and kinetics of pore formation by gasdermins. These studies aim to unravel novel pathways involved in chronic tissue damage and inflammatory diseases involving pyroptosis.
