G protein-coupled receptor (GPCR) Gpr17 expressed in hypothalamic Agouti-related peptide-expressing (AgRP) neurons increases appetite and glucose tolerance and insulin sensitivity. By contrast, increasing Gpr17 reduced glucose tolerance and increased appetite. Gpr17-agonists had no effect on FoxO1-deficient mice, indicating, together with other data, that Gpr17 is a Fox-O1 target. Certain embodiments are directed to methods for reducing appetite, increasing glucose tolerance and insulin sensitivity and treating diabetes by administering Gpr17 antagonists or inhibitory oligonucleotides. Appetite can be increased by administering Gpr17 agonists.
