Abstract

We have investigated the responsiveness to thyroglobulin (Tg) plus complete Freund's adjuvant (CFA) and B. pertussis in a variety of inbred and MHC congenic strains of rats in terms of both Tg-autoantibody titres and histological thyroiditis index. Severity of thyroiditis was strongly Tg-dependent and closely related to the RT.1-MHC haplotype. Phenotypic examination of the inflammatory thyroid infiltrate using single and double indirect immunofluorescence techniques revealed a high proportion of macrophages and T lymphocytes, mainly of the cytotoxic/suppressor subset, in the high responder strains. Thyroid epithelial class II MHC expression although not prominent was strain-restricted and related to the amount of Ia+ leukocyte infiltrate.
