WebApr 8, 2024 · Furthermore, it has been shown that GSDMD is essential for caspase-11-dependent IL-1β maturation . Therefore, to assess whether the activation of caspase-1, ASC, caspase-11, and GSDMD is involved in activation of NLRP6 in S. pneumoniae-infected macrophages, macrophages from wild-type (WT) and mutant mice were infected … WebJun 14, 2024 · GSDMD succination suppresses its interaction with caspases, which limits GSDMD processing, oligomerization, and the capacity to induce cell death, suggesting …
WebATP acts as a canonical activator to induce NLRP3 (NOD-like receptor family, pyrin domain containing 3) inflammasome activation in macrophages, leading to caspase-1/gasdermin D (GSDMD)-mediated pyroptosis. It remains unclear whether ATP can induce pyroptosis in macrophages when the NLRP3 pathway is … 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 …
