PG - 273-82 AB - Dendritic cells (DCs), which are the most effective professional antigen-presenting cells (APCs), initiate and regulate immune responses. In this report, we examine the role of DCs in the induction of autoimmune thyroiditis. Experimental autoimmune thyroiditis (EAT) induced by immunization with thyroglobulin (Tg) plus adjuvant is considered to be an animal model of autoimmune thyroiditis, and is categorized as a T cell-mediated autoimmune disease. To examine the contribution of DCs to EAT, naive DCs were purified from high responder B10BR mice and pulsed with various concentrations of porcine Tg (pTg). These pTg-pulsed DCs were transferred without adjuvant to syngenic BIOBR mice to induce EAT. Mice that had received pTg-pulsed DCs showed thyroiditis, and the degree of thyroiditis induced was positively correlated to the amounts of pTg used for the incubation (pulsing) of DCs. The severity of thyroiditis was also correlated to the amounts of anti-pTg IgG2a antibodies and IFN-gamma in the recipient sera, but not to IL-4 or IL-10, indicating that Th1 cells are mainly activated by pTg-pulsed DCs and attributable to the pathogenesis of EAT.
