Abstract
Binding of (-)3H]-dihydroalprenolol (3H-DHA) to lymphocytes from five thyrotoxic patients and five age- and sex-matched contents were examined to ascertain whether beta-adrenergic receptor number or binding affinity were altered in thyrotoxicosis. Whereas an increase in beta-adrenoceptor density has been reported in triiodothyronine-induced hyperthyroidism, we did not find changes in beta-adrenergic receptor density or binding affinity. In one patient studied sequentially, we did not find alteration in 3H-DHA bindings before or after the subject was rendered euthyroid. We conclude that lymphocyte beta-adrenergic receptor density and affinity are not altered in spontaneous hyperthyroidism.
