Abstract<\/h3>\n
\n

BACKGROUND:<\/h4>\n

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.<\/p>\n

OBJECTIVE:<\/h4>\n

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.<\/p>\n

METHODS:<\/h4>\n

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.<\/p>\n

RESULTS:<\/h4>\n

SP-induced scratching behavior and activation of cultured dorsal root ganglion neurons was dependent on Mrgprs rather than NK-1R.<\/p>\n

CONCLUSION:<\/h4>\n

We deduce that SP activates MrgprA1 on sensory neurons rather than NK-1R to induce itch.<\/p>\n<\/div>\n<\/div>\n
