Furthermore, we propose that these putative CD peptides bind to oligosaccharide residues on HLA class II molecules distal to the peptide-binding groove invoking recognition and binding by specialized subsets of gamma delta T cell receptor-bearing lymphocytes .
 ( protein: peptide-binding groove, None) , ( cell type: gamma delta T cell receptor-bearing lymphocytes, None) , ( protein: HLA class II molecules, None)
