Abstract

Male NZB/NZW F1 hybrid (B/W) mice survive their first year of life and die of lupus nephritis or lymphoid malignancy during the second year. Androgen therapy, even if delayed until 9 months of age, improves survival considerably. We report here that androgen therapy in aged B/W mice is associated with improved cell-mediated immune function as well as increased survival. Androgen treated mice have significantly augmented spleen cell responses to phytohaemagglutinin (PHA) and a decreased incidence of abnormal splenic suppressor activity. These results suggest that androgen may prolong survival in B/W mice in part through an effect on abnormally suppressive regulatory cells that impair T lymphocyte function.

摘要

雄性新西兰黑/新西兰白F1杂交(B/W)小鼠能活过一岁,并在第二年死于狼疮性肾炎或淋巴系统恶性肿瘤。雄激素治疗,即使推迟到9个月龄,也能显著提高生存率。我们在此报告,老年B/W小鼠接受雄激素治疗后,细胞介导的免疫功能得到改善,生存率也有所提高。接受雄激素治疗的小鼠对植物血凝素(PHA)的脾细胞反应显著增强,脾抑制活性异常的发生率降低。这些结果表明,雄激素可能部分通过对损害T淋巴细胞功能的异常抑制性调节细胞产生作用,从而延长B/W小鼠的生存期。
