COPs and POPs: modulators of inflammasome activity.
Inflammasomes represent molecular platforms for the activation of inflammatory caspases and are essential for processing and secretion of the inflammatory cytokines IL-1beta and IL-18. Multiple key proteins of inflammasomes contain caspase recruitment domains (CARDs) or pyrin domains (PYDs). Dissecting CARD- and PYD-mediated interactions substantially improved our understanding of the mechanism...
متن کاملNOX-free inflammasome activation.
In recent years, much has been learned about how the highly proinflammatory cytokines of the interleukin-1 (IL-1 ) cytokine family are regulated. These cytokines differ from other cytokines in that they are produced as biologically inactive proforms in the cytosol upon transcriptional induction. In a second step, the protease caspase-1 mediates the cleavage and release of the IL-1 family of cyt...
متن کاملPyrin- and CARD-only Proteins as Regulators of NLR Functions
Upon activation Nod-like receptors (NLRs) assemble into multi-protein complexes such as the NODosome and inflammasome. This process relies upon homo domain interactions between the structurally related Pyrin and caspase-recruitment (CARD) domains and adaptor proteins, such as ASC, or effector proteins, such as caspase-1. Although a variety of NLRP and NLRC complexes have been described along wi...
متن کاملInhibitory effects of Cheonggukjang extracts on radiation-induced micronucleus formation and inflammasome activation
Background: People are exposed to more radiation than before with the application of radiation technology. Radiation is known to induce damage to cell structure, DNA, chromosomes and nucleus. In this study, we showed that CGJ extract can inhibit radiation-induced chromosomal damage in vivo and NLRP7 inflammasome activation in vitro, suggesting that the compound from CGJ can Be considered as a t...
متن کاملInflammasome activation by Campylobacter jejuni.
The Gram-negative pathogen Campylobacter jejuni is the most common cause of bacterial foodborne disease worldwide. The mechanisms that lead to bacterial invasion of eukaryotic cells and massive intestinal inflammation are still unknown. In this study, we report that C. jejuni infection of mouse macrophages induces upregulation of pro-IL-1β transcript and secretion of IL-1β without eliciting cel...
