Anti-coreceptor antibodies profoundly affect staining with peptide-MHC class I and class II tetramers 1996-04-01 · Because the same MHC haplotypes that promote development of CD8 T cells can also cause deletion in the homozygous state, it could be argued that the AND and DO10 TCRs have a higher intrinsic affinity for class II molecules of these particular haplotypes and this higher affinity allows coreceptor-independent MHC recognition. 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). 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. The exact mechanism by which the DP thymocytes are committed to the appropriate T-cell lineage is not yet clear. Earlier investigations on CD4 versus CD8 lineage commitment 1998-09-01 · X-ray crystallography of several MHC class II molecules revealed a structure described as a dimer of heterodimers, or a superdimer.

Cite this chapter as: König R., Fleury S., Germain R.N. (1996) The Structural Basis of CD4 — MHC Class II Interactions: Coreceptor Contributions to T Cell Receptor Antigen Recognition and Oligomerization-Dependent Signal Transduction. Function CD4 is a co-receptor of the T cell receptor (TCR) and assists the latter in communicating with antigen-presenting cells. The TCR complex and CD4 bind to distinct regions of the antigen-presenting MHC class II molecule.

The response of CD4 + transfectants was not due to a cross-reaction of 1D1 TCR with MHC class II molecules, because the transfectants did not respond to splenocytes of H-2 b knockout mice, which were defective in the assembly of the MHC class I molecule/β2 microglobulin/peptide complex and did not expose the complex on cell surface. 2000-12-01 · In recent years, substantial progress has been made towards understanding the molecular basis for CD8 binding to class I MHC and the coreceptor's role in cytotoxic T-cell activation. Here, we review the structural, mechanistic and functional studies that point to a model of coordination of T-cell receptor and CD8 signaling that might provide the key to cytotoxic T-cell activation.
