Human leukocyte antigen-G is a neoclassical human leukocyte class Ⅰ b antigen which was observed to be restrictively expressed by the fetal-maternal inter-fate on the extravillous cytotrophoblast.

人类白细胞抗原－G(human leukocyte antigen-G， HLA-G)属于非经典的HLA-Ⅰ类抗原分子，早期的研究发现HLA-G的表达仅局限于母胎界面的绒毛外细胞滋养层。

From the early study of the pathogenesis of pre-eclampsia people have found its association with immunological function . In 1986 Ellis et al[1] had found that the extravillous chorionic cytotrophoblast contacting with the maternal tissue expressed high levels of Human leukocyte antigen-G, a major histocompatibility tissue-specific antigen . Extravillous chorionic cytotrophoblast with high levels expression of HLA-G proteins can invade the maternal deciduas and the maternal spiral arteries by displacing the endothelial lining and destroying most of the musculoelastic tissue of these arteries .

早期研究开始，许多学者即发现其与免疫学有密切关系，至1986年Ellis等[1]发现人类白细胞抗原(human leukocyte antigen，HLA) G分子高度表达在绒毛外滋养层细胞( extravillous cytotrophoblast，EVCT)上，即浸润至子宫蜕膜层甚至达子宫浅肌层以及子宫螺旋动脉内皮层，与母血及子宫组织直接接触的滋养细胞，这种独特的组织分布提示HLA-G分子在母胎免疫耐受方面起重要作用。

CD58, also was called lymphocyte function-associated antigen 3, is a surface glycoprotein expressed on many cell types, binds to the T lymphocyte surface glycoprotein CD2. This interaction is important in mediating T lymphocytes with target cells and antigen-presenting cells, and the T lymphocyte rosetting with erythrocytes. It plays an important role in mammal immune system.

CD58又称淋巴细胞功能相关抗原-3(Lymphocyte Function associated Antigen-3， LFA-3)，是存在于机体内多种细胞及血小板表面的一种糖蛋白，它可与CD2结合，从而介导T细胞与抗原递呈细胞等的黏附，此外，还可介导T细胞与绵羊红细胞形成Et花环，在机体免疫系统中具有重要作用。
