Leptin has numerous signaling pathways in the brain. One such pathway is through a neurotransmitter called alpha melanocyte stimulating hormone. When leptin levels rise, alpha MSH rises. If given to an animal, alpha MSH causes metabolic rate to rise and causes satiety (lack of hunger). A naturally occuring mutation blocks the function of alpha MSH. These mice, termed agouti for their yellow coat color, are obese, but not to the extent of the mice missing leptin.
