MHC class I presents to cytotoxic T cells; MHC class II presents to helper T cells. The CD4 co-receptor (first image, below) is expressed by helper T cells and CD4 binds to non-polymorphic regions of class II MHC acting as a co-receptor for the T-cell antigen receptor (TCR). It increases avidity between thymocytes and Key words: adhesion, binding, co-receptor. Abstract.

The generation of mature CD4 T cells from CD4+CD8+ precursor thymocytes usually requires corecognition of class II MHC by a TCR and CD4, while the production of mature CD8 T cells requires corecognition of class I MHC by a TCR and CD8. To assess the role of the CD4 coreceptor in development and lineage commitment, we generated CD4-deficient mice expressing a transgenic class II–specific TCR T cells possess MHC class II-speciﬁc TCR and MHC class I-speciﬁc TCR, respectively, which is consistent with MHC binding speciﬁcities of the coreceptors they express.

In MHC II-/-CD8α-/- mice, developing MHC class I (MHC I)-reactive thymocytes cannot rely upon CD8 for selection, but they also cannot be overwhelmed by efficient selection of MHC II-reactive thymocytes.

The extracellular D 1 domain of CD4 binds to the β2 region of MHC class II. Studies supporting this model have demonstrated that the in vivo maturation of T cells with mismatched MHC recognition and coreceptor expression (class I–specific TCR with CD4 and class II–specific TCR with CD8) can be rescued by constitutive expression of CD4 or CD8 transgenes (13, 18, 44, 9, 37, 11, 2).

In humans, both genes are located on chromosome 2 in position 2013-08-26 · MHCII-restricted TCRs need to interact with the nonstimulatory peptide-MHC (pMHC), showing peptide specificity for activation enhancers or coagonists. In contrast, the MHCI-restricted cells studied to date show no such peptide specificity for coagonists, suggesting that CD8 binding to noncognate MHCI is more important.
