Metastin, the product of metastasis suppressor gene KiSS-1, is proposed to be the natural ligand for the G-protein-coupled receptor GPR54, known also as AXOR12. This immunohistochemical study, using a rabbit polyclonal antiserum against the human metastin fragment (45-54)-NH2, showed that in rats metastin-like immunoreactivity (MTS-LI) was present in neurons of the nucleus of the solitary tract and caudoventrolateral reticular nucleus, and in cell processes of the spinal trigeminal tract and lateral reticular nucleus. MTS-LI was confined mainly to neurons and fibers at or caudal to the area postrema. In the spinal cord, MTS-LI cell processes formed a dense plexus in superficial layers I and II of the dorsal horn. The pattern of distribution of MTS-LI in the medulla and spinal cord suggests that this novel peptide may participate in autonomic and sensory neural signaling.
