  • Title: Anti-idiotypic immunity and autoimmunity. II. Idiotypic determinants of autoantibodies and lymphocytes in spontaneous and experimentally induced autoimmune thyroiditis.
    Author: Zanetti M, Barton RW, Bigazzi PE.
    Journal: Cell Immunol; 1983 Feb 01; 75(2):292-9. PubMed ID: 6831564.
    Abstract:
    In a previous report, it was demonstrated that heterologous anti-idiotypic antibodies to autoantibodies against rat thyroglobulin (ART) were capable of inhibiting the in vitro binding between ART and rat thyroglobulin. It has also been shown that repeated injections of anti-idiotypic antibodies into Buffalo (BUF) rats with spontaneous autoimmune thyroiditis were followed by a significant decrease in the levels of circulating ART. In this report, cross-reacting idiotypic determinants, detectable by rabbit anti-idiotypic antibodies to ART, are shown to also be present on ART from rats with experimentally induced autoimmune thyroiditis. In addition, antibodies to rat thyroglobulin from animals of various strains and species are shown to also express idiotypes cross-reacting with those of spontaneous ART of BUF rats. Finally, it is reported that idiotypic determinants similar to those of circulating ART are present on spleen lymphocytes from rats with autoimmune thyroiditis.
