The objective of this article was to review and summarize recent research on the molecular structure and biological function of the <i>alpha</i> toxin of <i>Clostridium perfringens</i>.

Each type of <i>C. perfringens</i> produces <i>alpha</i> toxin, which is one of the most important lethal and dermonecrotic toxins and is considered a primary virulence factor. <i>Alpha</i> toxin is a multifunctional metalloenzyme with phospholipase C and sphingomyelinase activities that simultaneously hydrolyze phosphatidylcholine and sphingomyelin. It can therefore destroy the integrity of cell membranes and eventually cause cell lysis. The clinical effects of <i>alpha</i> toxins are characterized by cytotoxicity, hemolytic activity, lethality, skin necrosis, platelet aggregation, and increased vascular permeability. Future research will concentrate on the pathogenesis of <i>a</i> <i>lpha</i> toxin exposure, clarifying the interaction between <i>alpha</i> toxin and the cell membrane and investigating the mechanism of activating platelet function.
