HLA在个体发育中的作用分析

HLA（人体白细胞抗原）首先发现于白细胞表面，是人类主要组织相容性抗原。后来研究发现，与这种抗原相关的HLA基因群是迄今已知的人体最复杂的基因系统，具有高度多态性。从受精卵的着床发育到个体的成熟，在整个人体发育的历程中，人类组织相容性抗原每时每刻都发挥着重要的作用。本文在说明HLA基因结构的基础上，从母胎耐受、胚胎及个体发育等方面阐述了HLA的功能。

On the role of HLA in the the Process of Human Body Development

HLA is discovered initially on leukin surface,which is the major histocompatibility antigen.The research later discovers that the gene group related to such a kind of antigen is the most complex gene system in human body,which is highly polymorphism.From the spermatiation ovum in mother to the mature of individual,during the process of human body development,the major histocompatibility antigen plays an important role.On the basist of HLA gene structure,t his essay explains the function of HLA from the enduration between mothers and babies,embryo and individual development.
