Abstract:
:Dendritic cells (DCs) comprise a small population of cells in the normal thyroid. These excellent antigen-presenting cells (APCs) are thought to be involved in the initiation of thyroid autoimmune reactions. However it is not known whether the APCs involved in this process are indeed DCs, or thyrocytes. Our aims were as follows: (1) to isolate DCs from the thyroid of normal Wistar rats and BB-DP rats prior to the development of lymphocytic thyroiditis; (2) to determine the T-cell stimulatory capability of such isolated thyroid DCs and to compare this capability to that of BB-DP thyrocytes and splenic DCs; and (3) to investigate the phenotype of isolated thyroid DCs and to compare it to that of splenic DCs; and (4) to investigate the capability of such thyroid DCs to regulate thyrocyte growth and function, and to compare it to our earlier reports demonstrating such capability with splenic DCs. Leukokcytic cell fractions were isolated from the thyroids of BB-DP and control Wistar rats of 7-20 weeks of age. The isolation steps included gentle enzymatic tissue disruption, the collection of non-plastic adherent cells and density gradient centrifugation of these cells to yield a low and a high density non-adherent fraction. The low density cell (LDC) fraction was composed of 50-75% leukocytes in both strains. These leukocytes were almost exclusively ED1+ monocytes or MHC-class II+ DC. The high density cell (HDC) fractions of both strains were composed of about 70% MHC-class II-negative thyrocytes and 30% ED1+ monocytes. The thyroid LDCs of both strains had an APC capability in syngeneic(syn)-MLR comparable to that of splenic DCs. However, the HDCs were extremely poor in syngeneic T cell stimulation. There was a difference in composition between the Wistar and the BB-DP LDC fractions: The Wistar LDCs were composed of 30-35% ED1+ monocytes and 15-20% typical MHC-II+ DCs, while BB-DP LDC fractions contained more ED1+ monocytes (about 70%), but fewer DCs (5-10%). In comparison to splenic DCs, thyroid DCs had a low CD80 and CD86 expression in both strains (i.e., an 'immature' phenotype). The LDCs of both animal strains were shown to decrease both basal and TSH-stimulated thyrocyte proliferation and T(3)release by about half. This report shows that a cell fraction enriched for monocytes and DCs can be isolated from the thyroids of both Wistar and BB-DP rats. The cells in this fraction were as capable as splenic DCs to act as T cell stimulators in syn-MLR. Since the thyroid HDCs (predominantly thyrocytes) were very poor at such T cell stimulation, thyroid monocytes and DCs (and not thyrocytes) are the prime candidates to act as immune accessory cells in the initiation of thyroid autoimmunity in the rat. Wistar thyroid LDCs differed in phenotype from BB-DP LDCs. The latter contained a lower percentage of DCs and a higher percentage of their precursors, the monocytes. Interestingly, a defect in the transition of monocytes to DCs has been described in another animal model of autoimmune thyroiditis/insulitis (the NOD mouse), as well as in thyroiditis and diabetic patients.
