"When I came to UF, I wanted to be able to make a difference in the world. By joining Dr. Cheng's lab, I able to help test ways to reduce mortality in diarrhea and increase quality of life in Inflammatory Bowel Disease. After joining, I realized there were some personal benefits gained, such as a family-like atmosphere and having a mentor to give me advice in all aspects of my college career."

Research Description

Calcium-Sensing Receptor Regulates Integrity of Tight Junction and Intestinal Barrier: Role of Nutrients
It is known that extracellular calcium is needed for tight junction formation in the intestine. Our lab suggest that this effect is via the Calcium Sensing Receptor (CaSR). Nutritional CaSR agonists are able to increase while CaSR antagonists are able to decrease intestinal barrier function. This suggest that modulation of CaSR activity may constitute a novel approach to prevent and treat barrier dysfunctional diseases such as Inflammatory Bowel Disease and Diabetes.
