15 صفحه اولEffect of glucocorticosteroids on epidermal Langerhans cells
The effects of topical and systemic administration of various glucocorticoids on the density of epidermal Langerhans cells (LC) were studied in guinea pigs. Glucocorticoids, such as betamethasone dipropionate and valerate, caused a marked decrease in LC demonstrable by staining for cell membrane ATPase activity and Ia antigens. By electronmicroscopy, LC also showed morphologic alterations. The ...
متن کاملEffects of ultraviolet radiation on Langerhans cells
Research on penetration of ultraviolet (UV) radiation into human skin shows that about 20% of UVA and 10% of UVB can reach the basal layer of the epidermis. As a consequence, Langerhans cells (LCs), located in suprabasal layers, are subject to the influence of the two types of UV radiation. This phenomenon leads to quantitative and qualitative alterations in LCs, including reduction in their nu...
