Multiple bacterial genera take advantage of the multifunctional utoprocessing repeats-in-toxin (MARTX) toxin to invade host cells1. Secretion of the MARTX toxin by Vibrio vulnificus, a deadly opportunistic pathogen that causes primary septicemia, the precursor of sepsis2-5, is a major driver of inf...

Vibrio vulnificus MARTX toxin effector domains differentially remodel the transcriptional response of intestinal epithelial cells
Vibrio vulnificus is an foodborne pathogen that can cause gastroenteritis and septicemia in humans. V. vulnificus secretes a multifunctional autoprocessing repeats-in-toxin (MARTX) toxin as an essential virulence factor to cause disease. MARTX toxins are pore-forming toxins that translocate multiple...

Direct cytotoxicity to host cells by the MARTX toxin underlies the hypervirulence of foodborne Vibrio vulnificus
Vibrio vulnificus causes severe necrotizing wound infections and life-threatening foodborne infections. While clinical isolates of V. vulnificus are well-established as human pathogens, the pathogenic mechanisms underlying the virulence of food-derived isolates, particularly in the case of wound inf...

MARTX toxins are large single polypeptide bacterial toxins that translocate multiple cytotoxic and functionally independent effector domains into the cytosol of a target eukaryotic cell. Pandemic Vibrio cholerae El Tor O1 strains secrete a MARTX toxin with three effector domains — the actin crosslin...
