previous studies have shown that the release of melanotropin from frog neurointermediate lobes is under the control of two neuropeptides : thyrotropin-releasing hormone ( trh ) stimulates , while neuropeptide y ( npy ) inhibits alpha-melanocyte-stimulating hormone ( alpha-msh ) secretion from intact neurointermediate lobes in vitro .
