G蛋白偶联受体(GPCR),神经激肽-1受体(NK 1 R),和它的首选配体,P物质(SP),在与免疫系统和选定的感染。NK 1 R和P物质在整个动物王国中无处不在。这一重要途径在许多细胞和组织中具有独特的功能。SP与其首选受体NK 1 R相互作用,导致核因子-κ-B(NF-κB)和促炎细胞因子的激活。NK 1 R有两种亚型,全长和截短形式。这些异构体具有不同的功能意义,并且在细胞信号传导能力方面不同。由P物质调节的促炎信号在细菌、病毒、真菌和寄生虫病以及免疫系统功能中是重要的。SP-NK 1 R系统是主要的1类视紫红质样GPCR配体-受体相互作用。
The G-protein coupled receptor (GPCR), Neurokinin-1 Receptor (NK1R), and its preferred ligand, substance P (SP), are reviewed in relationship to the immune system and selected infections. NK1R and substance P are ubiquitous throughout the animal kingdom. This important pathway has unique functions in numerous cells and tissues. The interaction of SP with its preferred receptor, NK1R, leads to the activation of nuclear factor-kappa-b (NF-κb) and proinflammatory cytokines. NK1R has two isoforms, both a full-length and a truncated form. These isoforms have different functional significances and differ in cell signaling capability. The proinflammatory signals modulated by substance P are important in bacterial, viral, fungal, and parasitic diseases, as well as in immune system function. The SP-NK1R system is a major Class 1, rhodopsin-like GPCR ligand-receptor interaction.
