The past several decades have witnessed a flourish of interest in the field of incretin biology. The importance of the two incretin hormones, glucose-dependent insulinotropic polypeptide (GIP) and glucagon-like peptide-1 (GLP-1), in health and disease is becoming more apparent as the prevalence of type 2 diabetes and other metabolic disorders escalates. Rodent models have become indispensable in the study of the physiological function of GIP and GLP-1; however, investigators have run into several roadblocks when untangling the regulation of incretin secretion in these systems. The low circulating levels of the incretin hormones combined with sensitivity of the currently available assays require substantial amounts of blood to be removed from an animal if the hormones are to be analyzed over a period of time. Because of these limitations, continuous monitoring of GIP and GLP-1 secretion becomes difficult. A more effective means of studying incretin secretion in small animal models is therefore desirable. This chapter evaluates the use of the lymph fistula rat as a model to study the secretion of incretins. Lymph fistula models, in a variety of animals, have been used for decades to study the absorption and transport of lipid and lipophilic compounds; however, only recently has the value of this model been appreciated as a tool to explore incretin secretion.
