Autologous mixed lymphocyte reaction in Graves' disease: relationship to clinical status.
The autologous mixed lymphocyte reaction (AMLR), i.e. the ability of T lymphocytes to proliferate when cultured with autologous non-T cell fractions, is an 'in vitro' phenomenon showing immunological memory and specificity, probably related to the cooperation ability of immunocompetent cells. We have evaluated AMLR in 27 patients with Graves' disease of varying clinical status (untreated and treated with antithyroid drugs, surgery or 131I). The results obtained show: Impaired AMLR in untreated patients (as in other autoimmune diseases). Significantly higher AMLR in cured patients, and that AMLR in cured patients varies with the treatment (higher after surgery or radioiodine than after medical treatment). These results are consistent with the hypothesis of a functional defect of T cells in Graves' disease, which improves when clinical remission is achieved.
