Anti-inflammatory activity of cationic peptides: application to the treatment of acne vulgaris.
Cationic antimicrobial peptides exhibit potent antimicrobial activity against clinically relevant microorganisms including Propionibacterium acnes. Recent studies showed that, in addition to the antimicrobial activity, these peptides can exhibit an anti-inflammatory effect. These properties make cationic peptides attractive drug candidates for the treatment of acne vulgaris, a disease with both bacterial and inflammatory components. This review focuses on the anti-inflammatory activity of cationic antimicrobial peptides and its application for the treatment of acne vulgaris. The anti-inflammatory activity of cationic peptides in acne vulgaris can be explained by their ability to both bind proinflammatory bacterial factors (e.g. lipoteichoic acid), sequestering them from the site of inflammation, and to inhibit the secretion of proinflammatory cytokines (e.g. tumor necrosis factor-alpha, IL-1) by host cells. These anti-inflammatory effects combined with potent antimicrobial activity may translate into a novel therapeutic option for acne vulgaris.
