A 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 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 کاملHedgehog Signaling Regulates Nociceptive Sensitization
BACKGROUND Nociceptive sensitization is a tissue damage response whereby sensory neurons near damaged tissue enhance their responsiveness to external stimuli. This sensitization manifests as allodynia (aversive withdrawal to previously nonnoxious stimuli) and/or hyperalgesia (exaggerated responsiveness to noxious stimuli). Although some factors mediating nociceptive sensitization are known, ina...
متن کاملHypothalamus Pituitary Adrenal axis and stimulatory G proteins signaling role in nociceptive changes induced by forced swim stress
Introduction: Different mechanisms are involved in stress induced analgesia (SIA) and hyperalgesia (SIH). Repeated stress induces development of tolerance to SIA. The role of HPA axis and Gs signaling pathway in these effects are investigated in the current study. Methods: Forced swim stress (5 min/day) in water (20±1 ºC) was employed to adult male Wistar rats (200-250 g). The nociceptive t...
متن کاملRole of neuromedin B in control of the release of thyrotropin in hypothyroid and hyperthyroid rats.
Neuromedin B (NB) is a recently discovered neuropeptide related to bombesin. It is localized to thyrotropes and we have previously shown that it directly inhibits thyrotropin (TSH) release from the anterior pituitary gland of euthyroid rats. In the current studies, we further evaluated the action of NB and antiserum directed against it in euthyroid rats and compared the actions with those in hy...
