Cofilin-1 is an essential redox sensor for NLRP3 inflammasome activation
Introduction NLRP3 has a pivotal role in nucleating the inflammasome, a cytoplasmic multiprotein complex that mediates the maturation of the proinflammatory cytokine interleukin1b (IL-1b) by activating caspase-1. Mutations in the gene encoding NLRP3 cause a spectrum of autoinflammatory disease, the cryopyrin-associated periodic syndromes (CAPS). It has been reported that generation of reactive ...
متن کاملDDX19A Senses Viral RNA and Mediates NLRP3-Dependent Inflammasome Activation.
The NLRP3 inflammasome plays a major role in innate immune responses by activating caspase-1, resulting in secretion of IL-1β and inflammatory pathologic responses. Viral RNA can induce NLRP3 inflammasome activation. However, none of the components of NLRP3 inflammasome has the ability to bind viral RNA. Therefore, it had been proposed that there might have been some unidentified cytosolic RNA ...
متن کاملThe linear ubiquitin assembly complex (LUBAC) is essential for NLRP3 inflammasome activation
Linear ubiquitination is a newly discovered posttranslational modification that is currently restricted to a small number of known protein substrates. The linear ubiquitination assembly complex (LUBAC), consisting of HOIL-1L, HOIP, and Sharpin, has been reported to activate NF-κB-mediated transcription in response to receptor signaling by ligating linear ubiquitin chains to Nemo and Rip1. Despi...
متن کاملPKM2-dependent glycolysis promotes NLRP3 and AIM2 inflammasome activation
Sepsis, severe sepsis and septic shock are the main cause of mortality in non-cardiac intensive care units. Immunometabolism has been linked to sepsis; however, the precise mechanism by which metabolic reprogramming regulates the inflammatory response is unclear. Here we show that aerobic glycolysis contributes to sepsis by modulating inflammasome activation in macrophages. PKM2-mediated glycol...
متن کاملHuman NLRP3 inflammasome activation is Nox1-4 independent.
The NLRP3 inflammasome can be activated by pathogen-associated molecular patterns or endogenous danger-associated molecular patterns. The activation of the NLRP3 inflammasome results in proteolytic activation and secretion of cytokines of the interleukin-1 (IL-1) family. The precise mode of activation of the NLRP3 inflammasome is still elusive, but has been postulated to be mediated by reactive...
