We use an imaging across scales approach to investigate the path of insulin biosynthesis, trafficking, secretion, and recycling in pancreatic β-cell during glucose and drug stimulation. This approach will allow us to see at what points in this system the insulin secretion pathway breaks down as many questions remain. By integrating the multiple levels of research, our goal is to have a comprehensive picture of diabetes and related metabolic diseases, to provide the basis for next generation drug and cell-therapy design.
Raymond Stevens' research group has made significant achievements in the field of structural and functional studies of G protein-coupled receptor (GPCR) related to essential human diseases such as diabetes and obesity (Science, 2020; Nature Communication, 2020; Nature, 2017). In recent years, our research group has targeted pancreatic islet β-cells, which play a key role in blood glucose regulation, and opened the boundaries of atomic, molecular, cellular, tissue and in vivo studies by means of imaging across scales. Part of our studies on the dynamic function of islet β-cells under physiological and pathological conditions have been published in Science Advances, 2020a; Science Advances, 2020b; Proc Natl Acad Sci U S A., 2022.
Raymond Stevens also actively contributes to translational research, with several medicines discovered/developed: Nesina, Kuvan, Pegvilase, Zeposia, Botox.
