摘要
P2 嘌呤受体最初被分为P2X和P2Y两种亚型 ,其后扩展到P2T、P2Z 和P2D亚型。 90年代发现 ,一些组织标本对UTP、ATP和ATPγS反应良好 ,而对α ,β MeATP和 2 MeSATP不敏感 ,此类受体被称为“P2U受体”。晚近又证明 ,存在一种对UTP敏感而对ATP不敏感的“嘧啶受体”。据此IUPHAR(Internationalunionofpharmacology)规定 ,任何被核苷酸激活的离子通道型和G蛋白偶联型受体的亚型均分别命名为P2Xn和P2Yn受体。随着分子生物学技术的发展以及上述受体的克隆和表达 ,此分类系统得到了有力的支持。
P 2 purinoceptors were first subdivided into P 2X and P 2Y subtypes, and later this classification was broadened to include P 2T , P 2Z and P 2D subtypes. In the 1990s, a new kind of receptors was found, which respond to UTP, ATP and ATPγS, but not to 2 MeSATP or α,β MeATP, this finding led to the definition of the so called “P 2U ” or “nucleotide” receptor. Most recent evidence demonstrated the existence of a pyrimidine receptor responding to UTP but not to ATP. For this case, IUPHAR (International Union of Pharmacology) committee recommended that P 2 purinoceptors be subdivided into P2X and P2Y subtypes, any subtypes of intrinsic ion channel be termed P2Xn, and any subtypes of G protein coupled receptor be termed P2Yn purinoceptors. With the development and application of the molecular biologic technique and the cloning and expression of the receptors, the classification was strongly confirmed.
