The roles of gastrointestinal hormones
The roles of gastrointestinal hormones:
A: Heterogeneity of hormones in enteroendocrine cells studied at a cellular and subcellular level and
B: The innervation of gastric hormone cells
There is a huge resurgence of interest in gut hormones, the products of enteroendocrine cells of the gastrointestinal tract. Along with this is a revolution in the understanding of the patterns of colocalisation of the hormones to which our laboratory has made substantial contributions. We have discovered complex patterns of colocalisation of hormones that differ considerably between species (e.g., Cho et al, 2015). In particular, the distributions and patterns of colocalisation in human differs considerably from that in other species (Martins et al, 2017; Fakhry et al, 2017). We have also discovered that hormones colocalised in the same cells are located in separate storage vesicles (Cho et al, 2014; Fothergill et al, 2017). Current experiments are aimed at further exploration of the patterns of colocalisation and the investigation of their physiological significance.
