Research direction:
Our lab has been working on investigating the molecular and cellular mechanisms during host anti-pathogen immune responses, aiming to identify novel regulators and mediators, thus providing therapeutic targets and strategies for treating associated inflammatory and autoimmune diseases. One of our major focuses is pyroptosis, a programmed inflammatory cell death triggered by cytosolic sensing of invasive infection and danger signals. Gasdermins (GSDMs), a family of homologous pore-forming proteins, were recently identified as key executioners of pyroptosis. Our previous work (and others) identified the N-terminal fragments of GSDMD (GSDMD-NT) liberated via inflammatory caspase cleavage assemble in cell membranes and form pores, disrupting cell membrane integrity and trigger pyroptosis. In another study, we screened 3,752 small molecules and identified disulfiram, a drug approved by FDA for treating alcohol addiction, as an inhibitor of GSDMD pore formation. Disulfiram blocks pyroptosis and cytokine release in cells and lipopolysaccharide-induced septic death in mice, providing new therapeutic indications for repurposing this safe drug to counteract inflammation and human diseases. Currently we are working on elucidating in depth the regulation and function of GSDMs at the root of host-pathogen interactions as well as their function in associated human diseases; Meanwhile, we are employing unbiased genome-wide CRISPR/Cas9 screen, high-throughput small molecules screen and structure-based drug design and optimization, to identify novel regulators or mediators involved in host defense against microbial pathogen infection.
