Neuropeptide S (NPS) is the endogenous ligand of a previously orphan receptor now named NPSR. In the brain NPS regulates several biological functions including anxiety, arousal, locomotion, food intake, learning and memory, pain and drug abuse. Mice lacking the NPSR gene (NPSR(-/-)) represent an useful tool to investigate the neurobiology of the NPS/NPSR(More)
Neuropeptide S (NPS) regulates various biological functions by selectively activating the NPS receptor (NPSR). Recently, the NPSR ligand [(t)Bu-D-Gly(5)]NPS was generated and in vitro characterized as a pure antagonist at the mouse NPSR. In the present study the pharmacological profile of [(t)Bu-D-Gly(5)]NPS has been investigated. [(t)Bu-D-Gly(5)]NPS(More)
Neuropeptide S (NPS) regulates various biological functions by selectively activating the NPS receptor (NPSR). Recently, epidemiological studies revealed an association between NPSR single nucleotide polymorphisms and susceptibility to panic disorders. Here we investigated the effects of NPS in mice subjected to the elevated T maze (ETM), an assay which has(More)
The peptide welding technology (PWT) is a novel chemical strategy that allows the synthesis of multibranched peptides with high yield, purity, and reproducibility. With this approach, a tetrabranched derivative of neuropeptide S (NPS) has been synthesized and pharmacologically characterized. The in vitro activity of PWT1-NPS has been studied in a calcium(More)
