Anti-coreceptor antibodies profoundly affect staining with peptide-MHC class I and class II tetramers serves as a T cell coreceptor for MHC class II antigen recognition and as a receptor for the human immunodeficiency virus (HIV). The SK3 antibody inhibits HIV binding to CD4+ cells. Flow cytometric analysis of CD4 expression on human peripheral blood lymphocytes.

The genes for the α and β chains of TCR were cloned from T-cell hybridoma 1D1, which was obtained by fusion of BWZ.36CD8α cells with CD8+ memory cells specific for the H-2Kb MHC class I molecule. 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 (Figure 1). Ii is known to bind to the MHC class II peptide‐binding groove via its class II‐associated Ii peptide (CLIP) region early in the biosynthetic pathway to prevent premature peptide binding. In this study we have genetically exchanged CLIP with peptides of either high or low affinity for the class II peptide binding groove and utilized the properties of Ii to manipulate MHC class II loading.

The mechanisms mediating the effects of CD4 on responses by T helper cells to stimulation of the antigen-specific T cell receptor (TCR) are still poorly understood. Thus, the kinetics of CD4 coreceptor expression during MHC II-specific positive selection determines the integrity of CD4 lineage choice, revealing an elegant symmetry between coreceptor kinetics and lineage choice. 2010-06-01 · Importantly, antibodies to CD4 (T4/Leu3 in humans; L3T4 in mice) were shown to block the MHC class II-mediated proliferation and function of T cells leading to the suggestion that CD4 was intimately involved in the cooperative recognition of MHC class II associated foreign antigen by T cells (5,7,8). 2009-09-18 · 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 (). 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).

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).
