Two Melanin-concentrating hormone receptors (MCHR) have recently been characterized: MCH-R1 and MCH-R2. These two receptors share approximately 38% homology.

  • MCH-R1 is expressed in all mammals.
  • MCH-R2 is only found in some primates and carnivores including dogs, ferrets and man.

Clinical significance

Antagonists might be useful in the treatment of obesity[1][2] and anxiety and depression.[3] An agonist might have possible utility as a treatment for osteoporosis.[4]

Research is ongoing for antagonists affecting MCH receptors R1 and R2.[5][6]
