Listeria monocytogenes is sensed by the NLRP3 and AIM2 inflammasome.
The inflammasome pathway functions to regulate caspase-1 activation in response to a broad range of stimuli. Caspase-1 activation is required for the maturation of the pivotal pro-inflammatory cytokines of the pro-IL-1beta family. In addition, caspase-1 activation leads to a certain type of cell death known as pyroptosis. Activation of the inflammasome has been shown to play a critical role in ...
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 کاملAutoimmune Disease in Nzb/bl Mice
The transplantation of spleen cells from old NZB/Bl mice with renal disease induced both the structural and the functional changes of membranous glomerulonephritis in young NZB/Bl mice within a few weeks and well in advance of its usual spontaneous occurrence. The development of hypergammaglobulinemia and lymphoid cell hyperplasia in the young mice indicated that immunologically competent cells...
متن کاملNuclear factor E2-related factor-2 (Nrf2) is required for NLRP3 and AIM2 inflammasome activation.
Despite the number of extensive studies on the immune function and signaling of inflammasomes in various diseases, the activating mechanism of inflammasome, especially the NLRP3 inflammasome, is not fully understood. Nuclear factor E2-related Factor-2 (Nrf2), a key transcription factor that regulates cellular redox homeostasis, has been reported to play both protective and pathogenic roles depe...
متن کاملAIM2 Engages Active but Unprocessed Caspase-1 to Induce Noncanonical Activation of the NLRP3 Inflammasome.
Inflammasomes are multimeric protein complexes that initiate inflammatory cascades. Their activation is a hallmark of many infectious or inflammatory diseases. Their composition and activity are specified by proinflammatory stimuli. For example, the NLRP3 inflammasome is activated in response to cell damage and K+ efflux, whereas the AIM2 inflammasome is activated in response to cytosolic DNA. ...
