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. 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-2K b MHC class I molecule. Retroviral transduction of the 1D1 TCR genes and the CD4 and CD8 coreceptor genes was used to obtain 4G4 thymoma variants that exposed the CD3 1.

Although the specificity of T cell recognition is determined by the interaction of T cell receptors with MHC/peptide complexes, the development of T cells in the thymus and their sensitivity to Ag are also dependent on coreceptor molecules CD8 (for MHC class I (MHCI)) and CD4 (for MHCII).

The Tcell coreceptors CD8 and CD4 bind to invariable regions of peptide-MHC class I (pMHCI) and class II (pMHCII) molecules, respectively, and facilitate antigen recognition by a number of mechanisms. Although the specificity of T cell recognition is determined by the interaction of T cell receptors with MHC/peptide complexes, the development of T cells in the thymus and their sensitivity to Ag are also dependent on coreceptor molecules CD8 (for MHC class I (MHCI)) and CD4 (for MHCII). The T cell coreceptors CD8 and CD4 bind to invariable regions of peptide‐MHC class I (pMHCI) and class II (pMHCII) molecules, respectively, and facilitate antigen recognition by a number of mechanisms.

CD4 is expressed on helper T cells and regulatory T cells, and is specific for MHC class II. CD8, on the other hand, specific for MHC class I, is expressed on cytotoxic T cells. Binding of the co-receptor to the MHC bring Lck in close proximity to the CD3 ITAMs. Recognition of antigen by cytotoxic T lymphocytes (CTL) is determined by interaction of both the T cell receptor and its CD8 coreceptor with peptide-major histocompatibility complex (pMHC) class I molecules.

The majority of HIV-1 virions captured by DCs are internalized into endosomal compartments and can either be processed for MHC class II (MHCII) presentation or enter into the cytosol via CD4/coreceptor for MHC class I (MHCI) presentation .

The role of the coreceptor molecules, The CD4 coreceptor can only stabilize TCR:MHC II complexes while the CD8 coreceptor can only stabilize the TCR:MHC I complex. Consequently, although How damaged cells present antigens from inside the cell on MHC I and are recognized by cytotoxic T cells. Created by Sal Khan.
