COMPLEX FORMED BY A PEPTIDE AND A MAJOR HISTOCOMPATIBILITY COMPLEX AT THE SURFACE OF PHAGES

摘要

The invention concerns a micro-organism, preferably a phage, having at its surface a complex consisting of a peptide (P) and a major histocompatibility complex (MHC). More particularly, it concerns a method for expressing a complex formed by a peptide (P) and a major histocompatibility complex (MHC) in a micro-organism so as to produce said complex and present it at a phage surface. The invention also concerns the resulting complexes and their uses for marking, sorting or modulating T cell activity in vitro and in vivo. The invention further concerns the use of the resulting P-MHC complexes for constituting banks of micro-organisms useful for screening and isolating antigenic peptides recognised by T cells.
