Studies raise hopes for invention of drugs to block anthrax toxin

Oct 25 (CIDRAP News) – Two studies published online by Nature this week help explain how anthrax toxin works, possibly paving the way for the development of drugs that could block the toxin's action. One group of researchers explains how it identified the cell-surface receptor that enables anthrax toxin to invade host cells, while another group describes the precise molecular structure of a key component of the toxin.
