Tissue factor pathway inhibitor (TFPI) is a major regulator of blood clotting. Receipt of recombinant TFPI (rTFPI) protected animals from death in Escherichia coli-induced severe sepsis models and is under evaluation in a phase III clinical trial involving patients with severe community-acquired pneumonia. Because the mechanism of action of rTFPI in acute bacterial infection is not well understood, we sought to identify and map rTFPI peptides that have antimicrobial activity against E. coli.
