title: Urotensin-II, a neuropeptide ligand for GPR14, induces c-fos in the rat brain.
abstract: The vasoactive peptide urotensin-II and its receptor, GPR14 (now known as UT receptor), are localised in the mammalian central nervous system. Accordingly, various centrally mediated effects of urotensin-II on behaviour, neuroendocrine hormones and neurochemistry have been described. To investigate neuroanatomical substrates for the central actions of urotensin-II, expression of the immediate early gene c-fos was examined following intracerebroventricular administration to rats. Urotensin-II increased Fos expression in the cingulate cortex and periaqueductal grey, suggesting important central roles for urotensin-II and its receptor.
