Building on their 2001 discovery of a cellular doorway used by anthrax toxin to enter cells, University of Wisconsin Medical School researchers have found a second anthrax toxin doorway, or receptor. The finding could offer new clues to preventing the toxin’s entrance into cells. The researchers also have found that when they isolated a specific segment of the receptor in the laboratory, they could use it as a decoy to lure anthrax toxin away from the real cell receptors, preventing much of the toxin from entering cells and inflicting its usually fatal damage.
