GSDMD membrane pore is critical for IL-1β release and antagonizing IL-1β by hepatocyte-specific nanobiologics is a promising therapeutics for murine alcoholic steatohepatitis

Excessive release of interleukin-1β (IL-1β) is well-known to provoke cascades of inflammatory responses thus contributing to the pathogenesis of alcohol-induced steatohepatitis (ASH), but the cellular mechanism that regulates IL-1β release during ASH remains unclear. Herein, we identified that gasdermin D (GSDMD) membrane pore is critical in mediating IL-1β hypersecretion from chronic ethanol or acetaldehyde-stimulated macrophages. Deletion of...
