Pyroptosis
Pyroptosis is a form of programmed cell death that is characterized by the release of cellular components, including the rupture of the cell membrane and the release of pro-inflammatory signals. It is distinct from apoptosis, or regular cell death, and is often involved in the host's defense against infections and the elimination of damaged or dying cells. Pyroptosis is typically mediated by proteins of the NLRP3 inflammasome, a complex of protein sensors that recognize damage or infection in the cell and trigger an inflammatory response. Once activated, pyroptotic cells may release substances that attract immune cells to the site of injury or infection, facilitating the clearance of pathogens and the repair of damaged tissues.
