Compared with control group(20 cases of thyroid follicular adenoma,TFA),the higher expressions of S-100 in HT(139.38±5.92 vs 59.47±11.69) and GD(119.42±14.48 vs 59.47±11.69) were observed respectively(p< 0.001).The increased positive expressions of CD83 which is known as a marker of mature and activated DCs in HT(22.58±13.96 vs 5.19±8.08) and GD(29.92±14.43 vs 5.19±8.08) were also found respectively(p<0.001). Serum TPO antibody(TPO-Ab,67.3±11.6%) and Tg antibody(Tg-Ab,59.8±10.1%) in HT were higher than those in GD(28.4±5.7%,23.1±4.9%) and TFA(6.1±3.4%,7.2±4.6%)(p<0.01).Serum TR-Ab in GD(16.3 ±5.6 U/L) was higher than those in HT(4.8±2.3 U/L) and TFA(2.5±1.2 U/L)(p<0.01).Our findings suggest that the high expression of DCs' markers may be related to the pathogenesis of HT and GD.The upregulation of both the number and the matured functions of DCs,may lead to present more antigens and to produce more auto-antibodies(such as Tg-Ab and TPO-Ab in HT,TR-Ab in GD),which may be involved in pathogenesis of the autoimmune thyroid diseases.Cellular & Molecular Immunology.2004;1(5):378-382.展开更多
