正如H-2系统为小鼠的主要组织相容性系统(Major Histocompatibility System)、或称主要组织相容性复合体(Major Histocompatibility Complex,简称MHC)一样,HLA系统是人类的MHC。它由一组紧密连锁的共显性复等位基因位点组成。现在已在人、猩猩、猕猴、猪、狗、兔、鸡、豚鼠、大白鼠、小白鼠等10种动物中明确鉴定出MHC。借鉴于对小鼠H-2系统的研究知识,近年来对HLA系统的认识亦日益深入。HLA系统不仅与同种器官移 Just as the H-2 system is a mouse major Histocompatibility System, or Major Histocompatibility Complex (MHC), the HLA system is human MHC. It consists of a tightly linked co-dominant multiple allele locus. MHC has now been clearly identified in 10 animals, including orangutans, macaques, pigs, dogs, rabbits, chickens, guinea pigs, rats and mice. Drawing on the research knowledge of mouse H-2 system, the cognition of HLA system has been deepened in recent years. HLA system not only with the same organ transplant
