Hypothalamic growth hormone (GH)-releasing hormone (GHRH) stimulates the synthesis and release of GH from the pituitary gland. barrier. Brain endothelial cells joined by tight junctions form the blood-brain barrier a “barrier” between the general circulation and the CNS. In this study we administered a GHRH antagonist (JV-1-42) and showed that after i.v. injection iodinated JV-1-42… Continue reading Hypothalamic growth hormone (GH)-releasing hormone (GHRH) stimulates the synthesis and release
