自Ehrlich提出系统的受体假说,受体概念的出现迄今已近百年。他是在免疫学研究中观察抗原、抗体间反应时得出这一设想的。他认为,受体是机体组织中化学性质明确的微小部分,当它们与正常的或者外来的化合物分子中在化学性质上可以互补的部分结合后,机体就会出现生理效应。为此,他给受体下的定义 Since Ehrlich proposed the systematic receptor hypothesis, the emergence of the concept of receptor has been nearly a hundred years so far. He is immunological studies in the observation of antigen, antibody response came to this idea. He believes that receptors are tiny, chemically defined parts of the body that, when combined with chemically and chemically complementary parts of normal or foreign compounds, have biological effects. To this end, he gave the definition of receptor
