[Short peptides: regulation of skin function during aging.].

Short peptides are applied for supporting skin function during ageing, because they can permeate the intact stratum corneum of the epidermis and affect the cells of the dermis. Short peptides are part of natural metabolism of cells and many of them have geroprotective properties. In the review we are considering the base sorts of peptides that are used for normalized skin fibroblasts function: matrikines, carnosine, collagen peptides, cytokine and growth factor analogs, defensins, immunoprotective peptides and polyfunctional peptides. Polyfunctional peptides (AcSDKP, KED, AEDG, AED) have geroprotective properties, slow apoptosis and stimulate skin cell proliferation, also increase functional activity of skin fibroblasts, normalize intracellular matrix hemostasis. Polyfunctional peptides are the antioxidants and immunoprotectors and can activate microcirculation in dermis. Peptide regulation of skin function during ageing are the fast-developing and prospective area in molecular gerontology.
