How the intestinal microenvironment controls propulsion and mixing of food in the gut: parallel transduction pathways

点击翻译按钮获取中文摘要

This project will identify the mechanisms that control the mixing of food with digestive juices, the absoprtion of nutrients from the gut to the blood stream and the excretion of waste. Disruption of these processes causes significant health problems and is associated with normal aging and many diseases. We will identify nutrients and other food components (eg spices) that switch gut from mixing to propulsion and hence identify targets to treat disorders of gut movement.
