Gasdermin Family: a Promising Therapeutic Target for Stroke

Stroke is one of the leading causes of death worldwide and therapies are limited. According to the mechanisms underlying stroke, direct cell demise, destruction of organelles, blood-brain barrier disruption, neuroinflammation are potential therapeutic targets. Gasdermin (GSDM) family is a series of recently discovered proteins, which acts as the executor of pyroptosis and protagonist of membrane pore formation. It can be cleaved by inflammatory caspases that are activated by multi-protein complexes, named as inflammasomes, and divided into two domains. The N-terminal domain interacts with lipid localized in the plasma membrane as well as organelle membrane and perforates them. After the formation of pores, the dysfunctional structures suffer lytic death and their contents are released. In this review, we discuss the biological characteristic of GSDM family and their possible roles in stroke-induced brain injury, and based on the review, we hypothesize the feasibility of using GSDMs as a potential target for stroke treatment.
