An excessive production of vasoactive and proinflammatory bradykinin-related peptides, the kinins, is often involved in the human host defense against microbial infections. Recent studies have shown that a major fungal pathogen to humans, Candida albicans, can bind the proteinaceous kinin precursor, the high molecular weight kininogen (HK) and trigger the(More)
Antimicrobial peptides are increasingly being explored as alternative agents for therapy against the parasitic protozoan Leishmania. Previously, we reported that the synthetic magainin analog, pexiganan, induced apoptosis of surface protease-deficient Leishmania. Here, we report the development of an arginine-rich variant of this peptide which has reduced(More)
