The gasdermin-D pore: Executor of pyroptotic cell death
Pyroptosis is a lytic type of programmed cell death that is initiated in response to pathogenor host-derived perturbations of the cytosol. It is characterized by cell swelling, lysis, and the release of cytoplasmic content; thus restricting the replication of intracellular pathogens and attracting effector cells of the immune system. The name pyroptosis derives from the Greek pyro (fire or feve...
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 کاملGSDMD membrane pore formation constitutes the mechanism of pyroptotic cell death
Pyroptosis is a lytic type of cell death that is initiated by inflammatory caspases. These caspases are activated within multi-protein inflammasome complexes that assemble in response to pathogens and endogenous danger signals. Pyroptotic cell death has been proposed to proceed via the formation of a plasma membrane pore, but the underlying molecular mechanism has remained unclear. Recently, ga...
متن کاملGasdermin D Exerts Anti-inflammatory Effects by Promoting Neutrophil Death
Gasdermin D (GSDMD) is considered a proinflammatory factor that mediates pyroptosis in macrophages to protect hosts from intracellular bacteria. Here, we reveal that GSDMD deficiency paradoxically augmented host responses to extracellular Escherichia coli, mainly by delaying neutrophil death, which established GSDMD as a negative regulator of innate immunity. In contrast to its activation in ma...
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)...
