HLA region of Chromosome 6 The human leukocyte antigen (HLA) system is a complex of genes on chromosome 6 in humans that encode cell-surface proteins responsible for regulation of the immune system. [1] The HLA system is also known as the human version of the major histocompatibility complex (MHC) found in many animals. [2]

HLA -II型 （HLA-DP, HLA-DM, HLA-DO, HLA-DQ, HLA-DR） 编码第二型MHC，将 细胞外 抗原呈递给CD 4+ T（T-helper cells 辅助T细胞），T细胞增殖，进而刺激B细胞产生抗原特异性抗体（体液免疫）。

人类白细胞抗原（human leukocyte antigen, HLA）是由HLA基因复合体所编码的产物，定位于第6染色体短臂上。 HLA系人类组织相容性复合体（MHC）的表达产物，是构成移植排斥反应的重要抗原物质。

2013年7月18日 · The Major Histocompatibility complex (MHC) system known as the human leukocyte antigen (HLA) in humans is located on the short arm of chromosome 6 (6p21.3) and contains the most polymorphic gene cluster of the entire human genome.

人类白细胞抗原（HLA）系统（人类主要组织相容性复合物 [MHC]是免疫系统重要组成部分），其对应的基因位于6号染色体。 这些基因负责编码细胞表面的专职抗原肽递呈分子，它们能将抗原肽递呈给T细胞表面的T细胞受体（T-cell receptor，TCR）。 （参见免疫系统概述。

HLA分型 (HUMAN LEUCOCYTE ANTIGEN），即 人类白细胞抗原)是一个由一系列紧密连锁的 基因座位 所组成的具有高度 多态性 的复合体。 主要组织相容性复合体 (major histocompatibility complex，MHC)是由染色体上一组编码与细胞间识别和抗原呈递相关蛋白的高度多态性基因组，在人类称HLA复合体。 HLA (humanleucocyteantigen)复合体是人类多态性最丰富的遗传系统，定位于第6号染色体短臂6P21.31区，长3600kb。 1999年已完成全部序列分析及基因定位，在此区 …

The human leukocyte antigen (HLA) system (the major histocompatibility complex [MHC] in humans) is an important part of the immune system and is controlled by genes located on chromosome 6. It encodes cell surface molecules specialized to present antigenic peptides to the T-cell receptor (TCR) on T cells. (See also Overview of the Immune System.)
