目前已知神经递质、神经调质、激素和生长促进因子通过与位于细胞表面的其选择性受体相互作用而表现出其多样的代谢和生理反应。这些表面受体通过产生所谓的第二信使来放大细胞外信号。其中包括肌醇磷酸和1,2-二酰基甘油(DG),其通过响应于受体刺激而水解膜结合的磷酸肌醇形成。这种双信使系统近年来引起了极大的关注,因为它参与了一系列生理过程,包括神经元膜兴奋性、突触传递、细胞代谢、肌肉收缩、感觉转导、运动、生长、DNA合成和血小板聚集。最近的几篇文章综述了这种受体信号系统的各个方面(1-15)。本文综述了近年来有关第二信使的代谢、作用方式、神经递质受体信号的调节以及与其他受体偶联效应物的相互作用等方面的研究进展。磷酸肌醇周转领域的爆炸性增长几乎触及了每一个主要的生物系统,对每个系统进行详细的回顾是不切实际的。因此,我集中在几个系统,特别是eNS和相关的神经组织中的磷酸肌醇代谢特别活跃。磷脂酰肌醇(PI)、4-磷酸磷脂酰肌醇(PIP)和4,5-二磷酸磷脂酰肌醇(PIP 2)统称为
Neurotransmitters, neuromodulators, hormones and growth-promoting fac­ tors are now known to exhibit their diverse metabolic and physiological responses by interaction with their selective receptors located on the cell surface. These surface receptors transduce and amplify extracellular signals by the generation of so-called second messengers. Among these are inositol phosphates and 1 ,2-diacylglycerol (DG) which are formed by hydrolysis of membrane-bound phosphoinositides in response to receptor stimulation. This dual messenger system has attracted enormous attention in recent years because of its involvement in an array of physiological processes, including neuronal membrane excitability, synaptic transmission, cellular metabolism, muscle contraction, sensory transduction, motility, growth, DNA synthesis, and platelet aggregation. Several recent articles review various aspects of this receptor-signaling system (1-15). This review focuses on recent de­ velopments concerning the metabolism of second messengers , their mode of action, the regulation of neurotransmitter receptor signalling, and the interac­ tion with other receptor-coupled effectors . The explosive growth of the field of phosphoinositide turnover has touched virtually every major biological system, and a detailed review of each system is impractical . I therefore concentrate on a few systems, in particular the eNS and related neural tissues where the metabolism of phosphoinositides is particularly active. Phosphatidylinositol (PI) , phosphatidylinositol 4-phosphate (PIP) and phosphatidylinositol 4, 5-bisphosphate (PIP2) are collectively referred to as
