蛋白介绍
Binds peptides derived from antigens that access the endocytic route of antigen presenting cells (APC) and presents them on the cell surface for recognition by the CD4 T-cells. The peptide binding cleft accommodates peptides of 10-30 residues. The peptides presented by MHC class II molecules are generated mostly by degradation of proteins that access the endocytic route, where they are processed by lysosomal proteases and other hydrolases. Exogenous antigens that have been endocytosed by the APC are thus readily available for presentation via MHC II molecules, and for this reason this antigen presentation pathway is usually referred to as exogenous. As membrane proteins on their way to degradation in lysosomes as part of their normal turn-over are also contained in the endosomal/lysosomal compartments, exogenous antigens must compete with those derived from endogenous components. Autophagy is also a source of endogenous peptides, autophagosomes constitutively fuse with MHC class II loading compartments. In addition to APCs, other cells of the gastrointestinal tract, such as epithelial cells, express MHC class II molecules and CD74 and act as APCs, which is an unusual trait of the GI tract. To produce a MHC class II molecule that presents an antigen, three MHC class II molecules (heterodimers of an alpha and a beta chain) associate with a CD74 trimer in the ER to form a heterononamer. Soon after the entry of this complex into the endosomal/lysosomal system where antigen processing occurs, CD74 undergoes a sequential degradation by various proteases, including CTSS and CTSL, leaving a small fragment termed CLIP (class-II-associated invariant chain peptide). The removal of CLIP is facilitated by HLA-DM via direct binding to the alpha-beta-CLIP complex so that CLIP is released. HLA-DM stabilizes MHC class II molecules until primary high affinity antigenic peptides are bound. The MHC II molecule bound to a peptide is then transported to the cell membrane surface. In B-cells, the interaction between HLA-DM and MHC class II molecules is regulated by HLA-DO. Primary dendritic cells (DCs) also to express HLA-DO. Lysosomal microenvironment has been implicated in the regulation of antigen loading into MHC II molecules, increased acidification produces increased proteolysis and efficient peptide loading.

文献和实验HLA-DPA1 and -DPB1 Typing Using the PCR and Nonradioactive Sequence-Specific Oligonucleotide Probes
The class II molecules of the human major histocompatibility complex are cell surface glycoproteins encoded by a series of genes located on the short arm of chromosome 6 in the HLA-D region. These molecules consist of an α and � chain
在免疫反应方面，基于抗原的刺激在体内形成、并与抗原作特异性结合的蛋白质之总称。其化学实质是免疫球蛋白。抗体，按照抗原抗体反应的类型可分别称为沉淀素、凝集素、溶血素、溶菌素、抗毒素、中和抗体等，但这些并不等于有相应的不同抗体存在，一般多只表明抗体反应的多样性而已。抗体在血清中含量最多（体液抗体=humoral antibody）；含有某特定抗体的血清称为抗血或免疫血清。
机体在抗原物质刺激下，由B细胞分化成的浆细胞所产生的、可与相应抗原发生特异性结合反应的免疫球蛋白。因为最初有人用电泳证明血清中抗体活性在γ球蛋白部分，故曾把抗体统称为两种（γ）球蛋白。后来证明，抗体并不都在γ区；而且位于γ区的球蛋白，也不一定都具有抗体活性。1964年，世界卫生组织举行专门会议，将具有抗体活性以及与抗体相关的球蛋白统称为免疫球蛋白（Ig）。如骨髓瘤蛋白，巨球蛋白血症、冷球蛋白血症等患者血清中存在的异常免疫球蛋白以及“正常人”天然存在的免疫
