melanin-concentrating hormone

A cyclic 19-residue orexigenic hypothalamic neuropeptide, which plays a key role in regulating feeding behaviour, mood, the sleep-wake cycle and energy balance.  It also has an autocrine role in regulating beta-cell mass dynamics and pancreatic islet cell secretion. Overexpression of MCH is associated with obesity; MCH knockout mice are underweight.

The LH has 3 distinct populations of neurons: neurons that produce orexin, neurons that produce melanin-concentrating hormone (MCH), and neurons containing isoform 65 of glutamic acid decarboxylase (GAD65), named "GAD65 neurons."

Melanocyte abnormality and destruction, melanin-concentrating hormone (MCH) MCH receptor autoantibodies, the overexpression of MCH, a high level of homocysteine, an increase in catecholamine, free oxygen radicals, cytomegalovirus and stress may be related to the pathogenesis of vitiligo (14-19).
Within the LHA, neurons expressing the wake-promoting peptides, orexins, are GI neurons, whereas neurons expressing the sleep-promoting neuropeptide melanin-concentrating hormone (MCH) are GE neurons [19, 20].

Vanderbilt's Roger Cone and his team demonstrated that the newly discovered protein, AgRP2, regulates expression of the prohormone genes pmch and pmchl, precursors to melanin-concentrating hormone, which has a pigment-lightening effect.

Melanin-concentrating hormone is the cognate ligand for the orphan G-protein-coupled receptor SLC-1.
The mice are genetically engineered to lack melanin-concentrating hormone, or MCH, which is made in the brain and is known to stimulate feeding.
The study, led by Shinjae Chung and Olivier Civelli, discovered how the melanin-concentrating hormone works with dopamine in the brain's "pleasure centre" to create an addictive response to cocaine use.
