Gsdmd activation
WebThis work demonstrates a critical role for NLRP3 inflammasome and GSDMD activation-mediated pyroptosis in acinar cells, linking pancreatic necrosis and systemic inflammation in AP. Targeting pyroptosis signalling pathways holds promise for specific AP therapy. WebJun 14, 2024 · Notably, the activation of GSDMD could also feed-back control the activation of inflammasome. For example, potassium can be released from the GSDMD pores, causing the activation of NLRP3 inflammasome (7, 71), providing a new connection between canonical inflammasome and GSDMD activation .

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 … WebApr 14, 2024 · Therefore, STING can activate the pyroptosis pathway of neurons. We subsequently found that the protein expression of P- IRE1α, NLRP1, ASC, Caspase-1 p20, N-GSDMD, IL-18, and IL-1β were remarkably upregulated in the cortex of mice subjected to TBI (Figures 4E–L). DNase 1 treatment significantly rescued the activation of the STING …
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 … WebApr 11, 2024 · Cytosolic LPS activates the NLRP3 inflammasome via a gasdermin D (GSDMD)-dependent mechanism. In this issue of Immunity, Zhu et al. provide insight into the events linking these two steps, identifying the orphan nuclear receptor Nur77 as a mediator of NLRP3 activation that senses LPS and GSDMD-dependent accumulation of …
