Molecular mechanisms and functions of pyroptosis, inflammatory caspases and inflammasomes in infectious diseases.
TLDR
The central role of inflammatory caspases and pyroptosis in mediating immunity to infection and clearance of pathogens is described.Abstract:
Cell death is a fundamental biological phenomenon that is essential for the survival and development of an organism. Emerging evidence also indicates that cell death contributes to immune defense against infectious diseases. Pyroptosis is a form of inflammatory programmed cell death pathway activated by human and mouse caspase-1, human caspase-4 and caspase-5, or mouse caspase-11. These inflammatory caspases are used by the host to control bacterial, viral, fungal, or protozoan pathogens. Pyroptosis requires cleavage and activation of the pore-forming effector protein gasdermin D by inflammatory caspases. Physical rupture of the cell causes release of the pro-inflammatory cytokines IL-1β and IL-18, alarmins and endogenous danger-associated molecular patterns, signifying the inflammatory potential of pyroptosis. Here, we describe the central role of inflammatory caspases and pyroptosis in mediating immunity to infection and clearance of pathogens.read more

TL;DR: It is demonstrated that activation of caspase-1 clears intracellular bacteria in vivo independently of IL-1β and IL-18 and establishes pyroptosis as an efficient mechanism of bacterial clearance by the innate immune system.

TL;DR: Purification and cloning of the complementary DNA indicates that IL-lβ-converting enzyme is composed of two nonidentical subunits that are derived from a single proenzyme, possibly by autoproteolysis.
