Human hypothalamic neuronal system revealed with a salmon melanin-concentrating hormone (MCH) antiserum

Abstract An antiserum raised against synthetic salmon melanin-concentrating hormone (MCH) reveals an extensive neuronal system in the posterior lateral areas of the human hypothalamus. These neurons correspond to those previously described in the rat, which are characterized by expression of MCH-like, α-melanotropin-like and human growth hormone-releasing factor (1–37)-like immunoreactivities.
