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.

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. MHC Class II molecules are a class of major histocompatibility complex (MHC) molecules normally found only on professional antigen-presenting cells such as dendritic cells, mononuclear phagocytes, some endothelial cells, thymic epithelial cells, and B cells. König R, Huang LY, Germain RN (1992) MHC class II interaction with CD4 mediated by a region analogous to the MHC class I binding site for CD8. Nature 356: 796–798 PubMed CrossRef Google Scholar König R, Shen X, Germain RN (1995) Involvement of both MHC Class II a and β chains in CD4 function indicates a role for ordered oligomeritation in T Cell activation. CD8 is a transmembrane glycoprotein that serves as a co-receptor for the T-cell receptor. Along with the TCR, the CD8 co-receptor plays a role in T cell signaling and aiding with cytotoxic T cell antigen interactions.

2000-04-01 · That is, CD4 is expressed by T cells with TCR specific for MHC class II molecules (MHC II), whereas CD8 is expressed by T cells with TCR specific for MHC class I molecules (MHC I). This concordance between coreceptor phenotype and TCR specificity is imposed during thymic selection of CD4 + 8 + precursor thymocytes (52, 56, 27). The major histocompatability class II heterodimer (class II) is expressed on the surface of both resting and activated B cells.

2009-09-10 · Results. To examine changes in CD4 coreceptor expression during MHC-II specific positive selection and their effect on MHC-II specific lineage choice, we compared MHC-II specific selection in mice that expressed CD4 coreceptor proteins under the control of either endogenous or transgenic transcriptional regulatory elements (Fig. 1).
