TRIM11 Suppresses AIM2 Inflammasome by Degrading AIM2 via p62-Dependent Selective Autophagy

Activates the Inflammasome via Aim2 Cutting Edge: Cytosolic Bacterial DNA

Microbial DNA regulates intestinal homeostasis via the AIM2 inflammasome

Absent in melanoma 2 (AIM2) is a cytosolic DNA sensor which upon activation assembles a multiprotein complex called the inflammasome. Previous studies have shown that several inflammasome-forming pattern recognition receptors exhibit a protective function against inflammatory bowel disease and colorectal cancer. However, the role of AIM2 in sensing intestinal microbial DNA and regulating inflam...

PKM2-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...

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 ...

Pyroptotic neuronal cell death mediated by the AIM2 inflammasome.

The central nervous system (CNS) is an active participant in the innate immune response to infection and injury. In these studies, we show embryonic cortical neurons express a functional, deoxyribonucleic acid (DNA)-responsive, absent in melanoma 2 (AIM2) inflammasome that activates caspase-1. Neurons undergo pyroptosis, a proinflammatory cell death mechanism characterized by the following: (a)...
