Furthermore, we have reported that it is more beneficial for the prevention of atherosclerosis to use incretin-based drugs at an early stage when incretin receptor expression in arterial cells is preserved. On the other hand, although clinical trials with imeglimin in human subjects clearly indicated its efficacy and safety, its precise mechanism on β-cells remained unknown. However, to address this clinical question, we performed some basic experiments and confirmed the beneficial effects of imeglimin on mitochondrial morphology in β-cells and/or the number and quality of insulin granules, which can explain the effects of imeglimin on β-cells observed in clinical practice.
