“受体”是一组细胞膜上或细胞内能识别信息分子的特殊蛋白分子,识别后立即与配体结合;效应器把其所携带的信息转换成生理效应(细胞功能和代谢改变等)。由于配体与受体结合异常,或结合后反应异常,或由于自身抗体而致受体功能异常所致的疾病叫“受体病”。能与机体自身(正常或改变了)的组织成分起反应的抗体叫自身抗体。针对机体自身组织成分 “Receptors” are a group of special protein molecules that can recognize information molecules on the cell membrane or in cells. Immediately after recognition, “Receptors” bind to ligands. Effectors transform the information they carry into physiological effects (changes in cell function and metabolism, etc.). A disease caused by an abnormal ligand binding to a receptor, or an abnormal reaction after binding, or an abnormal function of a receptor due to an autoantibody is called “receptor disease.” Antibodies that react with the body’s own (normal or altered) tissue components are called autoantibodies.
