紫外线(UV)在皮肤中的穿透力很小,但UV 对皮肤及对皮肤相关的免疫细胞影响的研究中发现,UV 发挥全身性的作用.如:对人体进行UV辐射后的数小时内,淋巴细胞的增殖力减弱,用中波紫外线(UVB)和短波紫外线(UVC)对离体免疫活性细胞辐射后,能消除淋巴细胞在混合白细胞培养中的刺激能力,消除淋巴细胞在丝裂素刺激培养中的辅助功能并阻止细胞毒效应的产生。用UV 辐射过的辅助细胞刺激淋巴细胞后,能使淋巴
Ultraviolet (UV) penetration in the skin is minimal, but studies of the effects of UV on the skin and on skin-related immune cells found that UV exerts a systemic effect such as within hours of UV radiation on the human body , Lymphocyte proliferation weakened by UVB (UVB) and shortwave ultraviolet (UVC) radiation of ex vivo immune cells, lymphocytes can eliminate the stimulation of mixed white blood cell culture ability to eliminate lymphocytes in the mitogen Stimulate the auxiliary functions in culture and prevent the generation of cytotoxic effects. Lymphocytes can be lysed after the lymphocytes are stimulated with UV-irradiated helper cells
