Melanin-Concentrating Hormone: From Metabolism to Sleep Disorders offers a comprehensive understanding of this multifunctional peptide. The book covers a wide range of topics, including molecular biology of MCH, MCH in organ function, pharmacology, and MCH in disease. Recent developments in MCH imaging and pharmacological modulation are explored, as well as the impact of MCH in psychiatric and neurodegenerative disorders, and its role in the neuroimmunological modulation of vitiligo. Additionally, MCH is considered in the context of reproductive behaviour, sleep, cognition and memory, and peripheral function. The book also explores MCH across various species such as humans, reptiles, non-primate mammals and teleosts. Melanin-Concentrating Hormone: From Metabolism to Sleep Disorders is a volume in the “Molecular Mediators in Health and Disease” series and is an ideal reference for researchers working with MCH across the fields of cell biology, molecular biology, pharmacology, neuroscience, endocrinology and beyond.
