Dual engagement of the NLRP3 and AIM2 inflammasomes by plasmodium-derived hemozoin and DNA during malaria.
Hemozoin (Hz) is the crystalline detoxification product of hemoglobin in Plasmodium-infected erythrocytes. We previously proposed that Hz can carry plasmodial DNA into a subcellular compartment that is accessible to Toll-like receptor 9 (TLR9), inducing an inflammatory signal. Hz also activates the NLRP3 inflammasome in primed cells. We found that Hz appears to colocalize with DNA in infected e...
متن کاملThe Cytokine Release Inhibitory Drug CRID3 Targets ASC Oligomerisation in the NLRP3 and AIM2 Inflammasomes
BACKGROUND The Inflammasomes are multi-protein complexes that regulate caspase-1 activation and the production of the pro-inflammatory cytokine IL-1β. Previous studies identified a class of diarylsulfonylurea containing compounds called Cytokine Release Inhibitory Drugs (CRIDs) that inhibited the post-translational processing of IL-1β. Further work identified Glutathione S-Transferase Omega 1 (...
متن کاملConcerted activation of the AIM2 and NLRP3 inflammasomes orchestrates host protection against Aspergillus infection.
Invasive pulmonary aspergillosis is a leading cause of infection-associated mortality in immunocompromised individuals. Aspergillus fumigatus infection produces ligands that could activate inflammasomes, but the contribution of these host defenses remains unclear. We show that two inflammasome receptors, AIM2 and NLRP3, recognize intracellular A. fumigatus and collectively induce protective imm...
متن کاملIRGB10 Liberates Bacterial Ligands for Sensing by the AIM2 and Caspase-11-NLRP3 Inflammasomes
The inflammasome is an intracellular signaling complex, which on recognition of pathogens and physiological aberration, drives activation of caspase-1, pyroptosis, and the release of the pro-inflammatory cytokines IL-1β and IL-18. Bacterial ligands must secure entry into the cytoplasm to activate inflammasomes; however, the mechanisms by which concealed ligands are liberated in the cytoplasm ha...
متن کاملShikonin Suppresses NLRP3 and AIM2 Inflammasomes by Direct Inhibition of Caspase-1
Shikonin is a highly lipophilic naphtoquinone found in the roots of Lithospermum erythrorhizon used for its pleiotropic effects in traditional Chinese medicine. Based on its reported antipyretic and anti-inflammatory properties, we investigated whether shikonin suppresses the activation of NLRP3 inflammasome. Inflammasomes are cytosolic protein complexes that serve as scaffolds for recruitment ...
