    • The present invention relates to a product and process for regulating the activity of T cells using major histocompatibility complexes (MHC) stably linked to antigenic peptides. Disclosed is an antigenic peptide covalently linked to a major histocompatibility complex (MHC) protein by a novel linker, thereby enabling the formation of a stable peptide-MHC complex, alone or in combination with additional MHC protein chains, capable of being recognized by a T cell receptor (TCR). Also disclosed is a nucleic molecule having a sequence encoding a Peptide-L-MHC molecule comprising an antigenic peptide joined by a linker to an MHC segment. The invention is additionally directed to formulations comprising an antigenic peptide joined by a linker to an MHC segment anchored in a lipid-containing substrate. Pharmaceutical reagents are also disclosed which contain an antigenic peptide joined by a linker to an MHC segment combined with a suitable carrier that is capable of presenting the Peptide-L-MHC molecule so that it is capable of being recognized by a T cell receptor.
