Human inter-α inhibitor proteins are endogenous human plasma proteins that function as serine protease inhibitors. Inter-α inhibitor proteins can block the systemic release of proteases in sepsis and block furin-mediated assembly of protective antigen, an essential stop in the intracellular delivery of the anthrax exotoxins, lethal toxin and edema toxin. ⋯ These human plasma proteins possess combined actions against anthrax as general inhibitors of excess serine proteases in sepsis and specific inhibitors of anthrax toxin assembly. Inter-α inhibitor proteins could represent a novel adjuvant therapy for the treatment of established anthrax infection.
