众所周知,机体的免疫稳定性是通过体液免疫和细胞免疫的相互协调实现的.近来,人们发现免疫系统受遗传控制,免疫应答基因(immune response gene,Ir基因)机能不全或障碍与自身免疫性疾病及恶性肿瘤有密切关系.现已知人类有二种Ir基因,分别与组织相容抗原系统(HLA复合体)和免疫球蛋白重链的结构基因(Gm同种异型)相连锁.本文著者测定了大肠癌病人的Gm同种
As we all know, the body’s immune stability is achieved through the coordination of humoral immunity and cellular immunity. Recently, it has been found that the immune system is under genetic control, immune response gene (Ir gene) insufficiency or dysfunction and autoimmune diseases There is a close relationship with malignant tumors. It is known that humans have two kinds of Ir genes, which are linked with the histocompatibility antigen system (HLA complex) and structural genes of the immunoglobulin heavy chain (Gm allotypes).
