Neuromedin U depolarizes rat hypothalamic paraventricular nucleus neurons in vitro by enhancing IH channel activity.
The effect of neuromedin U (NMU) on rat paraventricular nucleus (PVN) neurons was examined using whole cell patch-clamp recordings. Under current-clamp, 31% of PVN parvocellular neurons (n = 243) were depolarized by 100 nM NMU, but magnocellular neurons were not affected. NMU (10 nM to 1 microM) resulted in increased basal firing rate and depolarization in a dose-dependent manner with an EC50 o...
متن کاملIntrahypothalamic paraventricular nucleus-microinjected SKF 38393, D1 receptor agonist, reduces food intake in 24 hours food-deprived rats
Introduction: Dopamine plays an important role in the central nervous system for modulating food intake. Dopamine receptors are distributed within the hypothalamus, and expression of D1 receptors is significant in hypothalamic paraventricular nucleus (PVN). Therefore, the aim of this study was to find if PVN-microinjected SKF38393, D1 receptor agonist, may modulate food intake. Methods: Gui...
متن کاملOvarian regulation of neuromedin U and its local actions in the ovary, mediated through neuromedin U receptor 2.
Neuromedin U (NMU) was originally identified as an anorexigenic peptide that modulates appetite as well as energy homeostasis through the brain-gut axis. Although growing evidence has linked NMU activity with the development of female reproductive organs, no direct expression of and function for NMU in these organs has been pinpointed. Using a superovulated rat model, we found that NMU is direc...
متن کاملNeuromedin U receptor 2-deficient mice display differential responses in sensory perception, stress, and feeding.
Neuromedin U (NMU) is a highly conserved neuropeptide with a variety of physiological functions mediated by two receptors, peripheral NMUR1 and central nervous system NMUR2. Here we report the generation and phenotypic characterization of mice deficient in the central nervous system receptor NMUR2. We show that behavioral effects, such as suppression of food intake, enhanced pain response, and ...
