摘要
Naturally occurring CD4(+)CD25(+) regulatory T cells (Treg) are essential for the control of unwanted autoimmune responses. In this study, we analysed their frequency in peripheral blood and in the thymus/thymomas of patients with myasthenia gravis (MG). We found a marked decrease in the number of CD4(+)CD25(+) thymocytes in MG-associated thymomas, but no differences in the peripheral compartment, suggesting that the thymic development of Treg might be impaired in these patients.
