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...

Neuromedin B (NMB) (Minamino et al., 1983), a ten residue (GNLWATGHFM-NH2, Figure 1) neuropeptide, belongs to the ranatensin subfamily of bombesin-like peptides (Erspamer, 1980) which exhibits a wide range of biological responses in the central nervous system and gastrointestinal tract including thermoregulation (Marki et al., 1981), stimulation of the secretion of gastrointestinal hormones (Gh...

Although activation of G protein-coupled inward rectifying K+ (GIRK) channels by Gi/Go-coupled receptors has been shown to be important in postsynaptic inhibition in the central nervous system, there is also evidence to suggest that inhibition of GIRK channels by Gq-coupled receptors is involved in postsynaptic excitation. In the present study we addressed whether the Gq-coupled receptors of th...

Christoph Melcher, Rüdiger Bader, Steffen Walther, Oleg Simakov, Michael J. Pankratz We recently provided a molecular, neuroanatomical, and behavioral analyses of neurons expressing the neuropeptide gene hugin in Drosophila [1]. hugin-expressing neurons appear to comprise a neural circuitry in the brain that modulates feeding behavior in response to gustatory and nutrient signals. One of the qu...

Neuromedin U (NmU) is a regulatory peptide found in significant concentrations in both the brain and gut of the rat and is named according to its ability to powerfully contract the uterus. Two types of NmU receptors were recently identified and subsequent studies evidenced NmU involvement in the regulation of energy homeostasis. Such a role of neuromedin U suggests that a polypeptide may also b...

The aim of the present study was to investigate the expression and distribution of membrane receptors after bladder outlet obstruction (BOO). Partial bladder outlet obstruction (BOO) was induced in female rats and bladders were harvested after either 10 days or 6 weeks of BOO. The expression of different receptors was surveyed by microarrays and corroborated by immunohistochemistry and western ...
