Abstract:
:The dramatic clinical manifestations of toxigenic infections such as cholera and diphtheria occur without substantial bacterial invasion. Disease is mediated by the secretion of potent toxins that use ADP-ribosylation as the catalytic mechanism underlying their action. ADP-ribosylating toxins comprise a large family, including the cholera, diphtheria, pertussis and Escherichia coli heat-labile (LT) toxins, and all produce disease by altering key metabolic processes after transfer of an ADP-ribose moiety from NAD to specific host-cell target proteins. A new paradigm implicating ADP-ribosylation during intracellular pathogenesis is beginning to emerge from recent research in Salmonella.
