Abstract
In the first funding phase, we identified inhibitory GSDMD nanobodies that block GSDMD oligomerization, pore formation, pyroptosis, and cytokine secretion when expressed in the cytosol. Antagonistic nanobodies revealed both molecular insights into the mechanism of GSDMD pore formation, and offered an unexpected therapeutic angle to counteract GSDMD-mediated pyroptosis. In the second funding period, we will apply nanobodies to study pore formation by GSDMA and GSDME.

Former 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.
