RESUMO
We have previously prepared rabbit anti-idiotypic antibodies (anti-Ids) against the neutralizing monoclonal antibodies (MAbs) specific for the gp53 of bovine viral diarrhea virus (BVDV). The anti-Ids, purified by sequential immunoaffinity chromatography, inhibited the immunizing MAb from binding to the original antigens and blocked BVDV infection of cell cultures. This study evaluated immune responses in mice to the purified anti-Id reagents. BVDV-specific neutralizing antibodies were induced by the anti-Ids. The antisera (Ab3) induced by the anti-Ids immunoprecipitated gp53 from BVDV-infected Madin-Darby bovine kidney (MDBK) cell lysates. However, lymphocyte-proliferative responses were specific only for the respective immunizing antigens. These results suggest that the anti-Ids may bear an internal image of the gp53 to stimulate production of antibody but not to stimulate a virus-specific cellular immune response in mice.
