P物质(SP)通过激活肥大细胞和感觉神经元上的受体与瘙痒和炎症有关。越来越多的证据表明,除了其常规受体神经激肽-1外,SP还通过与MAS相关的G蛋白偶联受体(Mrna)发挥作用。由于Mrs 2介导的炎症的某些方面被认为是由神经激肽-1受体(NK-1 R)介导的,我们试图确定SP诱导的瘙痒是否也可以由Mrs 2介导。采用遗传学和药理学的方法,研究了Mrrabel对SP诱导的小鼠抓挠行为和培养的背根神经节神经元激活的作用。SP诱导的抓挠行为和培养背根神经节神经元的激活依赖于MrlR而不是NK-1 R。我们推断SP激活感觉神经元上的MrgprA 1而不是NK-1 R来诱导瘙痒。
Substance P (SP) is linked to itch and inflammation through activation of receptors on mast cells and sensory neurons. There is increasing evidence that SP functions through Mas-related G protein–coupled receptors (Mrgprs) in addition to its conventional receptor, neurokinin-1. Because Mrgprs mediate some aspects of inflammation that had been considered mediated by neurokinin-1 receptor (NK-1R), we sought to determine whether itch induced by SP can also be mediated by Mrgprs. Genetic and pharmacologic approaches were used to evaluate the contribution of Mrgprs to SP-induced scratching behavior and activation of cultured dorsal root ganglion neurons from mice. SP-induced scratching behavior and activation of cultured dorsal root ganglion neurons was dependent on Mrgprs rather than NK-1R. We deduce that SP activates MrgprA1 on sensory neurons rather than NK-1R to induce itch.
