运动对T淋巴细胞CD4^+、CD8^+亚群免疫的影响

Influence of Exercise to the Immunity of T-lymphocyte CD4^+、 CD8^+ Subsets

T淋巴细胞是机体免疫细胞中数目最多,作用最重要的功能细胞。T淋巴细胞CD4+、CD8+亚群是重要的免疫调节细胞。中小强度有规律的运动提高CD4+/CD8+比值,增强机体T淋巴细胞的免疫功能;而大强度、力竭运动则降低CD4+/CD8+比值,减弱T淋巴细胞的免疫功能。

T-lymphocyte is the greatest quantity among organic immunocytes, and the most important part of functional cells. T - lymphocyte CD4^ ＋ CD8^＋ subsets are the vital regulation immunocytes. Regular exercise of middle and minor strength can improve the proportion of CD4^＋/CD8^＋ ,and promote the organic T-lymphocytes immune function;But ex ercises of maximum or exhausted strength can decrease the proportion of CD4^＋/CD8^＋ ,and lessen the organic T- lymphocytes immune function.
