组胺和前列腺素(PGs)作为类自泌体发挥多种生理作用,其在其来源附近发挥作用并维持体内局部稳态。它们通过作用于与三聚体G蛋白偶联的特异性受体来刺激靶细胞。为了准确理解组胺和前列腺素的生理作用,有必要阐明其合成的分子机制以及受体介导的反应。我们克隆了小鼠L-组氨酸脱羧酶(HDC)和6种小鼠前列腺素受体(4种PGE 2受体、PGF受体和PGI受体)的cDNA。然后,我们描述了这些基因的表达模式和功能。此外,我们建立了HDC和PG受体的基因靶向小鼠品系,以探索组胺和PG的新的病理生理作用。我们在这里总结了我们的研究,这将有助于在HDC和PG受体的分子生物学的进展。
Histamine and prostaglandins (PGs) play a variety of physiological roles as autacoids, which function in the vicinity of their sources and maintain local homeostasis in the body. They stimulate target cells by acting on their specific receptors, which are coupled to trimeric G proteins. For the precise understanding of the physiological roles of histamine and PGs, it is necessary to clarify the molecular mechanisms involved in their synthesis as well as their receptor-mediated responses. We cloned the cDNAs for mouse l-histidine decarboxylase (HDC) and 6 mouse prostanoid receptors (4 PGE2 receptors, PGF receptor, and PGI receptor). We then characterized the expression patterns and functions of these genes. Furthermore, we established gene-targeted mouse strains for HDC and PG receptors to explore the novel pathophysiological roles of histamine and PGs. We have here summarized our research, which should contribute to progress in the molecular biology of HDC and PG receptors.
