Research Abstract

Cholix toxin (Cholix) is a novel ADP-ribosyl transferase cytotoxin produced by Vibrio cholerae. Cell death pathway induced by eEF2-ADP-ribosylation differs in various cell types. Cholix-induced apoptosis in HeLa cells is dependent on caspase activation, which is regulated by both mitochondria-dependent and -independent pathways. In conclusion, inflammatory caspases and caspase-8 were responsible for both mitochondrial signals and other caspase activation.
