摘要
精氨酸血管升压素(arginine vasopressin, AVP)参与机体水的重吸收、心血管稳态、激素分泌和社会行为等诸多生理过程的调控。AVP有三种受体亚型:V1a、V1b 和V2。血管升压素V2 受体(vasopressin V2 receptor, V2R)最初发现于肾脏集合管主细胞,主要参与调节肾脏对水的重吸收,但近年来,日益成熟的影像学及生物信息学等技术使研究者对V2R的微观结构、蛋白质结合与具体分布有了更多的了解,并通过异位过表达、激动或拮抗等方式发现V2R在很多疾病中的靶点作用。本文拟就近年来有关V2R的生理功能、病理生理机制与相关药物的研究现状进行简要综述。

Abstract
Arginine vasopressin (AVP) plays a crucial role in various physiological processes including water reabsorption, cardiovascular homeostasis, hormone secretion, and social behavior. AVP acts through three distinct receptor subtypes, i.e., V1a, V1b, and V2. Among them, the vasopressin V2 receptor (V2R) was initially discovered in the principal cells of renal collecting ducts, where it is primarily involved in regulating water reabsorption. However, in recent years, with the advancement of imaging and bioinformatics techniques, there has been a deeper understanding of the microstructure, protein binding capacity, and specific tissue distribution of V2R. Additionally, the pathogenic roles and target effects of V2R in various diseases have been uncovered through ectopic overexpression, activation, or antagonism. This paper aims to provide a brief overview of current research status on the physiological functions, pathophysiological mechanisms, and drug development related to V2R in recent years.
Key words: arginine vasopressin; vasopressin V2 receptor; vasopressin resistance; cyclic adenosine monophosphate
