Histatins: antimicrobial peptides with therapeutic potential

Therapeutic Potentials of Antimicrobial Peptides

Volume 5 • Issue 3 • 2013 Antimicrobial peptides (AMPs) are small proteins (<100 amino acids) which include alpha-defensins, beta-defensins and the cathelicidin LL-37 in humans [1]. Alpha-defensins are expressed in neutrophils as part of their non-oxidative antimicrobial mechanismsand are also found in Paneth cells in the intestine [2,3]. They are synthesized as precursors that are proteolytica...

Therapeutic antimicrobial peptides may compromise natural immunity.

Antimicrobial peptides (AMPs) have been proposed as a promising new class of antimicrobials despite warnings that therapeutic use could drive the evolution of pathogens resistant to our own immunity peptides. Using experimental evolution, we demonstrate that Staphylococcus aureus rapidly evolved resistance to pexiganan, a drug-candidate for diabetic leg ulcer infections. Evolved resistance was ...

Cationic antimicrobial peptides. A future therapeutic option?

Antimicrobial peptides for therapeutic applications: a review.

Antimicrobial peptides (AMPs) have been considered as potential therapeutic sources of future antibiotics because of their broad-spectrum activities and different mechanisms of action compared to conventional antibiotics. Although AMPs possess considerable benefits as new generation antibiotics, their clinical and commercial development still have some limitations, such as potential toxicity, s...
