ABSTRACT We have used the continuously growing FRTL-5 rat thyroid cell line to examine the regulation of major histocompatibility complex (MHC) class II (or la) antigen expression. Of the various stimuli investigated, only the supernatant from activated T cells or recombinant γ-interferon induced Ia expression. All Ia-inducing activity was removed from the T cell supernatant by acid dialysis, suggesting that γ-interferon is the single critical mediator for class II antigen expression. Its action was not TSH dependent but expression of class II antigens increased from the G0-G1 to the S and G2 phases of the cell cycle, so that TSH enhanced Ia expression by its action on cell division. Other agents including lectins, hormones, epidermal growth factor, a calcium ionophore and a phorbol ester did not induce Ia expression. Substances known to inhibit murine macrophage Ia expression (cortisol, prostaglandin E2 and 5-hydroxytryptamine) had no effect on FRTL-5 Ia expression. The use of this thyroid cell line has permitted direct examination of modulators in the absence of any possible effects from contaminating non-thyroid cells present in primary cultures and the results suggest that, of the agents tested, only γ-interferon has significance in the context of Ia antigen expression by the thyroid.

ABSTRACT We have examined the expression and function of rat CD54, a homologue of human intercellular adhesion molecule-1 (ICAM-1), by the continuously growing rat thyroid cell line FRTL-5. Approximately 10% of FRTL-5 cells express CD54 under basal conditions and this is not influenced by thyrotrophin. Expression of CD54 is increased by cytokines (γ-interferon, tumour necrosis factor, interleukin-1) and by an activator of C-kinase, phorbol 12-myristate 13-acetate. Blocking ICAM-1 with a monoclonal antibody directed against this molecule significantly (P <0·01) reduced the binding of splenic lymphocytes to FRTL-5 cells but inhibition was consistently greater (P <0·01) in the presence of antibodies against a rat homologue of lymphocyte function-associated antigen-1, the receptor on T cells for ICAM-1. In no case was complete blocking of cluster formation observed. These results show that a pure line of rat thyroid cells can express an ICAM-1 homologue and this is directly enhanced by cytokines. Expression of this homologue is partially responsible for lymphocyte adhesion to thyroid cells, which is likely to be a major event in T cell recognition of thyroid antigens in autoimmune thyroiditis.
