The taxonomy of enteroendocrine cells and their innervation
The hormone secreting cells of the gastrointestinal tract are essential for normal gut health and are targets for therapy. The organisation of these cells and their classification is undergoing revolutionary change
In this study you will use immunohistochemical methods, along with high resolution fluorescence microscopy and computer-aided image analysis to compare the distributions of EEC, their innervation and the colocalisation of hormones in human and in the model species of mouse, rat and pig.
The EEC signal to and receive signals from the nervous system, but their relationships with nerves are poorly understood.
The hormone secreting cells of the gastrointestinal tract are essential for normal gut health and are targets for therapy. Enteroendocrine cells (EEC) receive input signals from nerves and also signal to nerves. They are targeted for the treatment of disease, including diabetes. Recent studies from our and other labs show that the distributions of these cells are substantially different between species and that there are complex patterns of colocalisation of the hormones. A particular focus is cells containing 5-hydroxytryptamine.
