High-affinity binding of an influenza hemagglutinin-derived peptide to purified HLA-DR.

Abstract excerpt

Immunogenic peptides have been shown to bind detergent-solubilized class II (Ia) molecules from mice. In this investigation, we report that highly purified HLA-DR (DR) molecules in detergent solution are capable of binding a synthetic peptide (HAp) derived from the influenza hemagglutinin sequence. Although the presentation of this peptide has been demonstrated only to DR1-restricted Th cells, the association...
