AIM2 inflammasome is activated by pharmacological disruption of nuclear envelope integrity.
Inflammasomes are critical sensors that convey cellular stress and pathogen presence to the immune system by activating inflammatory caspases and cytokines such as IL-1β. The nature of endogenous stress signals that activate inflammasomes remains unclear. Here we show that an inhibitor of the HIV aspartyl protease, Nelfinavir, triggers inflammasome formation and elicits an IL-1R-dependent infla...
متن کاملListeria 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 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 کاملInnate Immunity: Cytoplasmic DNA Sensing by the AIM2 Inflammasome
Cytoplasmic double-stranded DNA triggers cell death and secretion of the pro-inflammatory cytokine IL-1beta in macrophages. Recent reports now describe the mechanism underlying this observation. Upon sensing of DNA, the HIN-200 family member AIM2 triggers the assembly of the inflammasome, culminating in caspase-1 activation, IL-1beta maturation and pyroptotic cell death.
متن کاملPyroptotic 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)...
