Abstract:

Pyroptosis is a type of programmed cell death mediated by the Gasdermin family. It is triggered in response to pathogen infection or other danger signals. The activation of Gasdermins leads to pyroptosis and the release of large amounts of inflammatory cytokines. Pyroptosis plays a crucial role in combating pathogen infections, as it helps to eliminate infected cells and activate the immune system. However, pathogens have already developed sophisticated strategies to evade or inhibit pyroptosis, allowing them to persist and facilitate infection. This review provides an overview of the discovery of pyroptosis and its importance in anti-infectious immunity. We also discuss several new strategies for inhibiting pyroptosis by pathogens. A thorough learning of the occurrence and regulation of pyroptosis may reveal the pathogenesis of related infectious diseases and contribute to developing effective anti-infective therapeutic strategies.

Key words: pyroptosis, pathogen, effector protein
