摘要	Gasdermin (GSDM) is a family of proteins that execute pyroptosis in vertebrate. In invertebrate, pyroptotic GSDM was documented only in coral. Recent studies identified abundant GSDM structural homologs in Mol-lusca, but their functions are unclear. Herein, we report a functional GSDM from Pacific abalone Haliotis discus (HdGSDME). HdGSDME is specifically activated by abalone caspase 3 (HdCASP3) cleavage at two distinct sites, generating two active isoforms with pyroptotic and cytotoxic activities. HdGSDME possesses evolution-arily conserved residues that proved to be essential to the N-terminal pore-formation and C-terminal auto -in-hibition capacities. Bacterial challenge activates the HdCASP3-HdGSDME pathway and induces pyroptosis and extracellular traps in abalone. Blockage of the HdCASP3-HdGSDME axis promotes bacterial invasion and host mortality. Collectively, this study reveals the existence of functionally conserved and yet distinct -featured GSDM in Mollusca and provides insights into the function and evolution of invertebrate GSDM.
