The Pore-Forming Protein Gasdermin D Regulates Interleukin-1 Secretion from Living Macrophages

Inflammasomes elicit pyroptosis or cell hyperactivation, with the latter defined as living cells that release IL-1. Evavold et al report that the pore-forming protein gasdermin D regulates IL-1 release from hyperactive macrophages. Cell- and liposome-based assays revealed that gasdermin D pores permit IL-1 passage across intact lipid bilayers.
