title: An immunochemical study of the lymphocyte A, Atri system.
abstract: The anti-Atri lymphocytotoxic antibodies reacting only with 5.19% of A, ABH-secreting individuals have been tested by an inhibition assay with 19 oligosaccharidic structures carrying the A, B, H or Lewis structures. The inhibitions observed dissociate the A and H blood group substances from the Atri substance, and seem to indicate the role of fucosyl residues, particularly that of fucosyl alpha (1 leads to 3), which may be the immunodominant of the Atri substance.
