Involvement of TGF-beta in Skin Photoaging
The goal of this thesis study was to understand the role of TGF-3 in skin photoaging, especially in solar elastosis. Solar elastosis, the accumulation of elastotic material in the dermal extracellluar matrix, is a major hallmark of photoaging. However, the mechanisms by which UV radiation causes solar elastosis are poorly understood. TGF-3 is a multifunctional cytokine involved in the regulatio...
متن کاملOverview of skin aging and photoaging.
Aging skin is an issue of concern to many patients. In this review aging and photoaging are defined, mechanisms which underlie these processes explored, and available treatment options discussed.
متن کاملSkin Photoaging and the Role of Antioxidants in Its Prevention
Photoaging of the skin depends primarily on the degree of ultraviolet radiation (UVR) and on an amount of melanin in the skin (skin phototype). In addition to direct or indirect DNA damage, UVR activates cell surface receptors of keratinocytes and fibroblasts in the skin, which leads to a breakdown of collagen in the extracellular matrix and a shutdown of new collagen synthesis. It is hypothesi...
متن کاملDietary Monounsaturated Fatty Acids Intake and Risk of Skin Photoaging
BACKGROUND Intake of monounsaturated fatty acids has been reported to reduce oxidative stress, insulin resistance and related inflammatory processes and may thus protect from skin photoaging. The objective of this study was to investigate the association between the risk of photoaging, monounsaturated fatty acids intake and the sources of monounsaturated fatty acids. METHODOLOGY/PRINCIPAL FIN...
متن کاملMechanisms and Pathophysiology of Photoaging and Chronological Skin Aging
Research conducted during the past 25 years has produced an understanding of the mechanisms that lead to connective tissue damage during chronological aging and as a result of chronic, repetitive exposure to ultraviolet (UV) radiation from the sun. While the etiologies of these two conditions are distinct, they share common pathophysiological mechanisms. In both conditions, upregulation of coll...
