激素、药物及神经递质,在调节和管理各种具有专一功能的细胞群体,完成整体协调的机能活动方面,起着关键的作用。靶细胞通过本身的受体对某些化学信息感受、识别,并作出初始反应,然后引起细胞机能的变化。故对各种正常的和病理的组织受体的测定,受到人们极大的重视。例如,临床医生要根据雌激素受体的存在与否,决定是否需要 Hormones, drugs and neurotransmitters play a key role in the regulation and management of a variety of cell populations with specific functions and in the coordination of overall functional activities. Target cells through their own receptors on some of the chemical information to feel, identify, and make an initial response, and then lead to changes in cell function. Therefore, the determination of a variety of normal and pathological tissue receptors, great attention by people. For example, clinicians decide whether they need or not based on the presence or absence of an estrogen receptor
