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)...
متن کاملDisruption of glycolytic flux is a signal for inflammasome signaling and pyroptotic cell death
When innate immune cells such as macrophages are challenged with environmental stresses or infection by pathogens, they trigger the rapid assembly of multi-protein complexes called inflammasomes that are responsible for initiating pro-inflammatory responses and a form of cell death termed pyroptosis. We describe here the identification of an intracellular trigger of NLRP3-mediated inflammatory ...
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 کاملLive-cell visualization of gasdermin D-driven pyroptotic cell death.
Pyroptosis is a form of cell death important in defenses against pathogens that can also result in a potent and sometimes pathological inflammatory response. During pyroptosis, GSDMD (gasdermin D), the pore-forming effector protein, is cleaved, forms oligomers, and inserts into the membranes of the cell, resulting in rapid cell death. However, the potent cell death induction caused by GSDMD has...
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.
