摘要

Specificity in the immune system is dictated and regulated by specific recognition of peptide/major histo- compatibility complex (MHC) complexes by the T cell recep- tor. Such peptide/MHC complexes are a desirable target for novel approaches in immunotherapy because of their highly restricted fine specificity. Recently, phage display was used to isolate an antibody that has T cell receptor-like specificity. It recognizes mouse MHC class I H-2K~k molecules complexed with a H-2K~k-restricted influenza virus-derived hemaggluti- nin peptide (Ha) but does not bind to class I H-2K~k alone, peptide alone, or H-2K~k complexed with other peptides.
