Effects of sex steroid hormones on neuromedin S and neuromedin U2 receptor expression following experimental traumatic brain injury
Objective(s): Neuroprotective effects of female gonadal steroids are mediated through several pathways involving multiple peptides and receptors after traumatic brain injury (TBI). Two of these peptides are including the regulatory peptides neuromedin U (NMU) and neuromedin S (NMS), and their common receptor neuromedin U2 receptor (NMUR2). This study investigates the effects of physiological do...
متن کاملComparison of feeding suppression by the anorexigenic hormones neuromedin U and neuromedin S in rats.
We compared the central mechanisms of feeding suppression by the anorexigenic hormones neuromedin U (NMU) and neuromedin S (NMS) in rats. I.c.v. injection of either NMU or NMS dose dependently decreased 3-h food intake during the first quarter of a dark period. Pretreatment involving i.c.v. injection of a specific anti-NMS IgG blocked the suppression of food intake induced by i.c.v.- and i.p.-i...
متن کاملFour amino acid residues are critical for high affinity binding of neuromedin B to the neuromedin B receptor.
Three mammalian bombesin receptor subtypes have been characterized: the gastrin-releasing peptide receptor (GRP-R), the neuromedin B receptor (NMB-R), and bombesin receptor subtype 3 (BRS-3). In a previous report we identified four amino acids that are critical for high affinity binding of bombesin and gastrin-releasing peptide (GRP) to the GRP-R. These four amino acids are conserved in all spe...
متن کاملA nociceptive signaling role for neuromedin B.
Here we used an array-based differential screen to uncover the expression of the neuropeptide neuromedin B (NMB) in the trigeminal ganglia of mice. Double-labeling experiments reveal NMB is expressed in a subset of sensory neurons that colabel with calcitonin gene-related peptide and TRPV1 suggestive of a role for NMB in nociception. Indeed, administration of NMB antagonist greatly attenuates e...
متن کاملAppetite-modifying actions of pro-neuromedin U-derived peptides
Neuromedin U (NMU) is known to have potent actions on appetite and energy expenditure. Deletion of the NMU gene in mice leads to an obese phenotype, characterized by hyperphagia and decreased energy expenditure. Conversely, transgenic mice that overexpress proNMU exhibit reduced body weight and fat storage. Here, we show that central administration of NMU or the related peptide neuromedin S (NM...
