Distinct Licensing of IL-18 and IL-1β Secretion in Response to NLRP3 Inflammasome Activation
Inflammasome activation permits processing of interleukins (IL)-1β and 18 and elicits cell death (pyroptosis). Whether these responses are independently licensed or are "hard-wired" consequences of caspase-1 (casp1) activity has not been clear. Here, we show that that each of these responses is independently regulated following activation of NLRP3 inflammasomes by a "non-canonical" stimulus, th...
متن کاملInflammasome activation and IL-1β target IL-1α for secretion as opposed to surface expression.
Interleukin-1α (IL-1α) and -β both bind to the same IL-1 receptor (IL-1R) and are potent proinflammatory cytokines. Production of proinflammatory (pro)-IL-1α and pro-IL-1β is induced by Toll-like receptor (TLR)-mediated NF-κB activation. Additional stimulus involving activation of the inflammasome and caspase-1 is required for proteolytic cleavage and secretion of mature IL-1β. The regulation o...
متن کاملMultiple Cathepsins Promote Pro-IL-1β Synthesis and NLRP3-Mediated IL-1β Activation.
Sterile particles induce robust inflammatory responses that underlie the pathogenesis of diseases like silicosis, gout, and atherosclerosis. A key cytokine mediating this response is IL-1β. The generation of bioactive IL-1β by sterile particles is mediated by the NOD-like receptor containing a pyrin domain 3 (NLRP3) inflammasome, although exactly how this occurs is incompletely resolved. Prior ...
متن کاملMetabolic Disturbances as a Result of Hepatopathy
The liver is the largest organ in the body, but its relative size varies among species. The liver performs many critical functions that maintain homeostasis. Liver functions include synthesis of cholesterol and bile acids and the generation and utilization of glycogen. It also is the site for metabolism of various substances in preparation for their excretion from the body via the bile or urine...
متن کاملCaspase-1 activation of interleukin-1β (IL-1β) and IL-18 is dispensable for induction of experimental cerebral malaria.
Malaria infection is initiated by sporozoite invasion of hepatocytes and asexual reproduction of liver stages, processes that are regarded to be "clinically and diagnostically silent." Merozoites, which egress from hepatocytes, infect erythrocytes in periodic cycles and induce disease. How the host innate immune system contributes to disease outcomes and to the induction of effector cells durin...
