Secretion of Glucagon Like Peptide (GLP-1) from intestinal L-cells in equine hindgut
This project aims to explore the role of acetate on the secretion of Glucagon Like Peptide 1 (GLP1) from intestinal L-cells in the equine hindgut. The currently understood role of GLP-1 in the digestive tract is to respond to nutrients (primarily glucose) in the small intestine to then stimulate the pancreas to produce insulin. The presence of intestinal L-cells and secretion of GLP-1 in the equine hindgut has been demonstrated in previous studies. However, it is unknown if microbial byproducts will stimulate intestinal L-cells to produce GLP-1. This project will collect intestinal tissue to incubate in the presence of acetate or glucose to enable the measurement of secreted GLP-1 via an ELISA in the incubation medium. Please contact Dr. Danielle Fitzgerald d.smith8@uq.edu.au or Dr. Viviana Gonzalez-Astudillo v.gonzalez@uq.edu.au for more information.
