Abstract:
:Although anthrax toxin was identified as a major Bacillus anthracis virulence factor over 50 years ago, defining the physiologically relevant targets has been challenging. Liu et al. demonstrate that intoxication of myeloid-derived cells contributes to establishing infection but is not required for mortality resulting from high toxin concentrations associated with end-stage disease.
