title: [Evolution of anti-Rh antibodies idiotypy in a blood donor over 9 years].
abstract: Anti-idiotypic sera were obtained in Rabbits immunized with Rh antibodies (isolated from the serum sample collected in 1974 from a Blood Donor). The sera agglutinate, at high titers, red cells coated with the immunizing antibodies and, at different titers, cells coated with antibodies from serum samples taken at other periods. Inhibition of hemagglutination of anti-idiotypic sera by different samples from the same Donor was complete with the immunizing serum and partial with other samples. These results show that idiotypes or idiotypic specificities appeared or disappeared during the period studied and represent the first observation on evolution of antibody idiotypy in Man.
