机体内几乎所有的激素都是通过与其特异的受体结合而发挥生理作用。激素受体一般定位于细胞膜、细胞浆和细胞核上。其中含氮类激素的受体存在于细胞膜,类固醇激素的受体存在于胞浆和细胞核,而甲状腺激素的受体则广泛分布于细胞膜、胞浆、线粒体膜、微体膜以及细胞核上。本文着重讨论甲状腺激素与其 Almost all the hormones in the body play a physiological role by binding to their specific receptors. Hormone receptors are generally located in the cell membrane, cytoplasm and nucleus. The receptors for nitrogen-containing hormones are present in the cell membrane. Steroid hormone receptors are found in the cytoplasm and the nucleus. Thyroid hormone receptors are widely distributed in the cell membrane, cytoplasm, mitochondrial membrane, micromembrane and nuclei. This article focuses on thyroid hormone and its
