Research Abstract |
We have investigated the tissue localization and biological functions of novel bioactive peptides NERPs. Immunoreactive NERPs were present in lateral nucleus of the hypothalamus and colocalized with orexin. NERP-2, but not NERP-1, enhanced food intake in a manner dependent on the neuropeptides orexins. Bioactivity of NERPs required carboxy-terminal amidation. This study demonstrated that NERP-2 is a novel orexigenic bioactive peptide.
