Cell-type-specific anthrax toxin receptor CMG2-null mice are generated and used to show that the Bacillus anthracis toxins lethal toxin (LT) and oedema toxin (ET) target distinct cell types; in contrast to previous suggestions, it is shown that endothelial cells are not key targets for either toxin and instead LT targets cardiomyocytes and vascular smooth muscle cells whereas ET targets hepatocytes.
