摘要：

Melanin-concentrating hormone (MCH), which is an orexigenic peptide, was isolated and identified as the endogenous ligand of the SLC-1 receptor. We established a CHO cell line expressing the rat SLC-1 receptor to search for its endogenous ligand. The extract of rat whole brain showed inhibition of intracellular forskolin-induced cAMP accumulation in rat SLC-1-expressing CHO cells and was purified. Using HPLC purification, we isolated and identified RICH as the endogenous ligand of the SLC-1 receptor. The authentic RICH demonstrated a dose-dependent inhibitory effect on cAMP accumulation in forskolin-stimulated rat and human SLC-l-expressing CHO cells with an EC50 value of 0.2 nM for both the rat and human SLC-1 receptors, This is the first description of the functional receptor for MCH.
