Molecular Mechanisms of Pyroptosis

Abstract

Pyroptosis is a regulated form of cell death that leads to inflammation and plays a role in many different diseases. Pyroptosis was initially defined by the dependence on caspase-1, a protease which is activated by innate immune signaling complexes called inflammasomes. Caspase-1 cleaves the protein gasdermin D, releasing the N-terminal pore-forming domain, which inserts into the plasma membrane. Recent studies have revealed that other gasdermin family members form plasma membrane pores, leading to lytic cell death, and the definition of pyroptosis was revised to gasdermin-dependent cell death. In this review, we discuss how the use of the term pyroptosis has changed over time, as well as currently understood molecular mechanisms leading to pyroptosis and functional consequences of this form of regulated cell death.

Keywords: ASC; Gasdermin; Inflammasome; Macrophage; Pyroptosis; Regulated cell death.
