遗传影响人类的生存能力,其中包括免疫反应能力的个体差异。早有证据表明免疫反应受免疫反应基因(Ir)控制,而Ir基因是和编码白细胞抗原(HLA)的组织相容性复合体MHC连锁的。本研究通过比较儿童及老年两组随机人群的HLA频率分布,观察到HLA确与生存能力有关。材料与方法一、调查对象: 1.老人组:江苏省徐州地区65岁至104
Genetically affect human viability, including individual differences in immune response capacity. There is already evidence that the immune response is controlled by the immune response gene (Ir), which is linked to the histocompatibility complex MHC encoding the leukocyte antigen (HLA). In this study, by comparing HLA frequency distribution in randomized children and elders, it was observed that HLA is indeed associated with viability. Materials and methods First, the survey: 1. Elderly group: Xuzhou, Jiangsu Province, aged 65 to 104
