Key Concepts in T-cell Receptor (TCR) 1. T-cell antigen receptor (TCR) is similar to the F(ab) of Ab but only located on the surface of T cells => No secreted form => Two major types: ab TCR and gd TCR 2. TCR functions to recognize Ag peptide and then to activate T cells =...
n 主要组织相容性,同种异体移植物(allograft)移植后,常发生免疫排斥反应,引起这种排斥反应的起决定性作用抗原称为主要组织相容性抗原(major histocompatibility antigen,MHA)。n 在同种异体移植免疫排斥反应中,其决定性作用的一组连锁基因及其编码产物,称为主要组织相容性复合体(major histocompatibility complex, MHC)。

Synonyms Major histocompatibility complex class II antigen , HLA-DP , HLA-DQ , HLA-DR (human) , H-2IA , H-2IE (mouse) , RT1.B, RT1.D (rat) Definition T cells recognize protein-derived antigens, and T cell activation depends on antigen presenting cells (APC). APC degrade proteins...
Various new findings from the area of cell biology have consequences for MHC class I and MHC class II antigen presentation. The immune system is a relatively late addition in our progress through evolution, and many immune-specific molecules exist. Unique functions of some of these, including ...

antigen presentation on MHC class I and IImolecules to CD8 + and CD4 + T cells. A better understanding of the molecularmechanisms by which the macroautophagy machinery is distributed between itscanonical and non-canonical functions should allow targeting of antigens to thesedifferent pathways to inf...
Subsequent epitope spreading depended on antigen presentation and was compartmentalized by major histocompatibility complex (MHC). B cells carrying two MHC haplotypes could bridge the MHC barrier between B cells that did not share MHC. Thus, B cells directly relay autoreactivity between two separate ...
In previous studies of antigen presentation by epithelial cells from the FRT of the rat, it was demonstrated that uterine epithelial and stromal cells both present antigen, and that presentation to CD4+ T cells is mediated through MHC class II [17]. Moreover, it was shown that antigen ...
