硒对免疫系统的影响 硒对细胞保持氧化还原平衡和清除活性氧起重要作用,最起码的作用是延缓衰老,硒缺乏可减少T细胞上的JL-2受体和抑制其表达,抑制T细胞增殖和分化,降低淋巴细胞的细胞毒作用。体外试验硒缺乏可导致白细胞对内皮细胞的粘附增加。这些硒缺乏所致的免疫系统的改变与肿瘤的易患性增加,一些
Effects of Selenium on the Immune System Selenium plays an important role in keeping the redox balance and scavenging of reactive oxygen species. The most important role is to delay aging. Selenium deficiency can reduce and suppress JL-2 receptor on T cells and inhibit T cells Proliferation and differentiation, reduce the cytotoxic effect of lymphocytes. In vitro tests of selenium deficiency can lead to increased leukocyte adhesion to endothelial cells. Some of these changes in the immune system due to these selenium deficiency are associated with increased cancer susceptibility
