Regulatory mechanisms of feeding Absorption of nutrients in the digestive tract Regulation of metabolism by amino acids
Generally speaking, leptin is secreted by fat cells and is known to act on the brain to suppress appetite and increase energy expenditure. But how many of us know that leptin is secreted by the stomach? At the Laboratory of Animal Metabolism and Function, we have been conducting pioneering research into the effects of leptin in the gastrointestinal tract on nutrient absorption in birds. Recently, we have shown that leptin inhibits glucose absorption via a receptor expressed in the intestinal epithelium of chickens. The mechanism of nutrient absorption in the gastrointestinal tract is still a mystery to be solved.
