在过去的几年中,我们的知识神经递质受体的急剧增加,受体类型和亚型已通过开发的选择性拮抗剂,神经药理学研究和放射性配体结合研究确定。与此同时,神经递质及其相关酶的免疫细胞化学定位也取得了重大进展。然而,直到最近免疫细胞化学被用于定位神经递质受体,这些研究一直是有限的。四种受体已被定位在中枢神经系统与免疫细胞化学:烟碱乙酰胆碱受体,β-肾上腺素能受体,GABA/苯二氮卓受体,甘氨酸受体。在这些受体中,甘氨酸受体的特征最为彻底。甘氨酸受体的免疫反应是高度集中在突触后的网站,和免疫反应的分布似乎与甘氨酸能神经元密切相关。然而,对其他受体进行的免疫细胞化学研究表明,这种分布可能并不总是如此。一些受体可能不集中在突触后部位,受体分布可能并不总是与相应神经递质的分布紧密吻合。其他受体的纯化和选择性抗体的生产工作正在迅速进展,这将使免疫细胞化学研究能够解决这些问题和其他问题。
Over the last several years our knowledge of neurotransmitter receptors has increased dramatically as receptor types and subtypes have been identified through the development of selective antagonists, neuropharmacological studies, and radioactive ligand binding studies. At the same time major advances were made in the immunocytochemical localization of neurotransmitters and their related enzymes. However, only recently has immunocytochemistry been used to localize neurotransmitter receptors, and these studies have been limited. Four receptors have been localized in the CNS with immunocytochemistry: the nicotinic acetylcholine receptor, the beta-adrenergic receptor, the GABA/benzodiazepine receptor, and the glycine receptor. Of these the glycine receptor has been the most thoroughly characterized. Glycine receptor immunoreactivity is highly concentrated at postsynaptic sites, and the distribution of immunoreactivity appears to correlate closely with glycinergic neurons. However, immunocytochemical studies done on other receptors suggest such a distribution may not always be the case. Some receptors may not be concentrated at postsynaptic sites, and receptor distribution may not always closely fit the distribution of the respective neurotransmitter. Work is rapidly progressing on the purification of other receptors and on the production of selective antibodies which will allow immunocytochemical studies which address these and other questions.
