Pyroptosis is a type of programmed cell death that features pore formation on the plasma membrane, cell swelling and plasma membrane disruption. Pyroptosis is a form of lytic programmed cell death initiated by inflammasomes, which detect cytosolic contamination or perturbation.

Gasdermin D (GSDMD), as the executive protein of pyroptosis, is activated and transferred to the membrane to induce glial rupture, resulting in the release of more inflammatory mediators.

Inflammasome is an intracellular signaling complex of the innate immune system. Activation of inflammasomes promotes the secretion of IL-1β/IL-18 and triggers pyroptosis. The proinflammatory effect of IL-1β/IL-18 and pyroptosis contributes to the development of autoimmune and inflammatory diseases.
