Pannexin-1 channels bridge apoptosis to NLRP3 inflammasome activation

Mol Cell Oncol. 2019 May 7;6(4):1610324. doi: 10.1080/23723556.2019.1610324. eCollection 2019.

Abstract

Apoptosis can promote inflammation by triggering activation of the NLRP3 inflammasome (NLR family, pyrin domain containing 3). However, the molecular mechanisms regulating these processes are ill-defined. We recently reported that pannexin-1 is required to promote NLRP3 inflammasome assembly. We further demonstrate that differential cleavage of gasdermin D (GSDMD) by apoptotic caspases regulates inflammatory cell lysis. Here, we discuss our findings and perspectives for future studies.
