Mice genetically deficient in neuromedin U receptor 2, but not neuromedin U receptor 1, have impaired nociceptive responses.

Neuromedin U (NMU) has recently been reported to have a role in nociception and inflammation. To clarify the function of the two known NMU receptors, NMU receptor 1 (NMUR1) and NMU receptor 2 (NMUR2), during nociception and inflammation in vivo, we generated mice in which the genes for each receptor were independently deleted. Compared to wild type… (More)
