WebMar 8, 2024 · Given the complexity of NLRP3 inflammasome signaling cascades, activation of various target proteins can be suppressed in many ways, including blockade of upstream signals, inhibition of inflammasome assembly, suppression of caspase-1 activation, prevention of GSDMD cleavage, and arrest of inflammatory cytokines production (Zahid … WebOct 22, 2024 · Here, we found that Nlrp3 CA/+;Gsdmd −/− mice, when challenged with LPS or TNF-α, still secreted IL-1β and IL-18, indicating inflammasome activation independent of GSDMD. Accordingly, Gsdmd −/− macrophages failed to secrete IL-1β and undergo pyroptosis when briefly exposed to NLRP3 inflammasome activators but released these …
Mechanism and Regulation of Gasdermin-Mediated Cell Death
WebFeb 3, 2024 · As the final downstream effector of inflammasomes activation, GSDMD is cleaved by inflammatory caspases at the junction between the N-terminal cytotoxic domain (GSDMD-p30) and C-terminal ... WebApr 11, 2024 · In this study, Zhu and colleagues discovered that the orphan nuclear receptor Nur77 is required for NLRP3 inflammasome activation downstream of caspase-11-mediated GSDMD cleavage. Nur77 binds to both cytosolic mtDNA and LPS via its DNA-binding domain (DBD) and ligand-binding domains (LBDs), respectively. This allows … thailandonthego.com

WebMay 21, 2024 · GSDMD is a substrate of inflammatory caspases; however, the cleavage mechanism of GSDMD activation is not well defined in cardiomyocytes. Therefore, we wanted to determine whether GSDMD was directly cleaved by inflammatory caspases. Our study revealed that caspase-11 expression was strongly induced in cardiomyocyte … Web15 hours ago · GSDMD-dependent killing of intracellular L. monocytogenes is also suspected because exogenous activation of NLRP3 via LPS + nigericin reduced recovery of viable L. monocytogenes from infected immortalized BMDMs and knockdown of Gsdmd increased colony-forming units by approximately threefold [41].
