摘要：

Understanding the molecular mechanisms that regulate beta cell mass and proliferation is important for the treatment of diabetes. Here, we identified domperidone (DPD), a dopamine D2 receptor (DRD2) antagonist that enhances beta cell mass. Over time, islet beta cell loss occurs in dissociation cultures, and this was inhibited by DPD. DPD increased proliferation and decreased apoptosis of beta cells through increasing intracellular cAMP. DPD prevented beta cell dedifferentiation, which together highly contributed to the increased beta cell mass. DRD2 knockdown phenocopied the effects of domperidone and increased the number of b cells. Drd2 over-expression sensitized the dopamine responsiveness of beta cells and increased apoptosis. Further analysis revealed that the adenosine agonist 50-N-ethylcarboxamidoadenosine, a previously identified promoter of beta cell proliferation, acted with DPD to increase the number of beta cells. In humans, dopamine also modulates beta cell mass through DRD2 and exerts an inhibitory effect on adenosine signaling.
