IP Status: PCT Patent Application Filed; Application #: PCT/US2019/044605 Better binding affinity for co-receptor CD4. New enhanced-affinity MHCII molecules could improve current research tools for the study of CD4 T cells during cancer, infections, and autoimmune disease.

between MHC class I and class II proteins led to the speculation that CD4 might bind to the membrane proximal b 2 domain of the MHC class II molecule in a manner analogous to CD8-class I.

Interaction of CD4 with MHC class II molecules plays a crucial role during thymlc development.

It is generally thought that the ability of these coreceptors to enhance T-cell responses is due to two main effects: (i) Binding of CD4 and CD8 to MHC class II and class I molecules helps stabilize weak T-cell receptor (TCR)-pMHC interactions; and (ii) the Src kinase, Lck, which is bound to the cytoplasmic tail of coreceptors, is efficiently recruited to the TCR complex upon coreceptor binding to the MHC, thereby enhancing the initiation of TCR signaling (3, 4).

CD4 is a coreceptor on T helper (Th) cells that interacts with MHC class II molecules (MHCII). 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). The major histocompatability class II heterodimer (class II) is expressed on the surface of both resting and activated B cells.

dimeric CD4 is the preferred coreceptor for binding to MHCII. Strategies to promote dimerization of CD4 should, therefore, en- hance the immune response, while inhibiting dimer formation is The first is the coreceptor, CD8 for class I MHC molecules, and CD4 for class II molecules. Most thymocytes differentiate through a double-positive stage in which they express both CD4 and CD8; it is the double-positive thymocyte that undergoes the initial round of positive selection. MHC class II-specific T cells can develop in the CD8 lineage when CD4 is absent.

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.
