Abstract
An EA rosette technique is used to study ontological development and organ distribution of Fc(IgG) receptor-bearing lymphoid cells in normal CS White Leghorn chickens, and in OS chickens with spontaneous autoimmune thyroiditis. During the embryonic period, no difference was seen between CS and OS in the tissue distribution of cells with Fc receptors. At the time of hatching and subsequently, the OS chickens possessed relatively more Fc receptor-bearing lymphoid cells than did CS chickens. The increase of Fc receptor-bearing lymphoid cells was most prominent among spleen cells. No difference in the affinity of Fc receptors between lymphocytes of the OS and CS chickens was demonstrated. The possible role of Fc receptor-carrying cells in the development of autoimmune thyroiditis is discussed.
