Adipocytes from thyroidectomized rats contain 3 times less [3H]dihydroalprenolol-binding sites (beta-adrenergic receptors) than adipocytes from euthyroid animals. This alteration is not solely due to cell-size differences, but also to a thyroidectomy-induced defect in beta-adrenergic receptor density per adipocyte surface area, a defect that is furthermore corrected by tri-iodothyronine treatment.
甲状腺切除大鼠的脂肪细胞中[3H]二氢阿普洛尔结合位点(β-肾上腺素能受体)的数量比甲状腺功能正常动物的脂肪细胞少3倍。这种改变不仅是由于细胞大小的差异,还归因于甲状腺切除引起的每个脂肪细胞表面积β-肾上腺素能受体密度的缺陷,而且这种缺陷可通过三碘甲状腺原氨酸治疗得到纠正。
