在回顾TRAb在Graves病中的作用时,不再需要对TSAb本身的作用进行辩论。这种抗体通常被认为是通过与TSH受体的一种成分结合并刺激腺苷酸环化酶而引起甲状腺功能亢进。以前,我们使用了一种基于测量人甲状腺切片中cAMP增加的测定方法,并在102名患者中发现了超过90%的TSAb(1)。现在,由Kasagi等人(2)开发并由Rapoport和他的同事(3)改进的程序已经取代了切片测定。该技术需要在原代单层培养物中用患者IgG在低渗培养基中孵育人甲状腺细胞,随后测量已释放到培养基中的cAMP。使用该测定,我们发现来自Graves病患者的IgG的100%阳性结果。这种高灵敏度显然与特异性降低无关,这是由90多例非自身免疫性甲状腺疾病患者的IgG阴性结果判断的。目前的替代和更方便的程序是在连续培养中类似地使用功能性大鼠甲状腺(FRTL-5)细胞(4),但并非所有人甲状腺细胞试验中的IgG阳性在该系统中均产生反应。
In reviewing TRAb in Graves’ disease there is no longer need for debate about the role of TSAb itself. This antibody is generally accepted as causing hyperthyroidism through binding to a component of the TSH receptor and stimulation of adenylate cyclase. Formerly we used an assay based upon measurement of an increase in cAMP in human thyroid slices and found TSAb in over 90% of 102 patients (1). Now the procedure developed by Kasagi et al (2) and refined by Rapoport and his colleagues (3) has replaced the slice assay. This technique entails incubation of human thyroid cells in primary monolayer culture with patients’ IgG in hypotonic medium and subsequent measurement of cAMP that has been released into the medium. With this assay we find 100% positive results with IgG from Graves’ disease patients. This high sensitivity apparently is not associated with decreased specificity as judged by negative results with IgG from over 90 patients with thyroid disorders of nonautoimmune origin. A current alternate and more convenient procedure is the similar use of functioning rat thyroid (FRTL-5) cells in continuous culture (4), but not all IgG positive in the human thyroid cell assay give- a response in this system.
