Outline of Final Research Achievements

Neuroendocrine Regulatory Peptide-4 (NERP-4) was co-expressed with insulin in the pancreatic β cells of human, mice and rat. Ca2+ imaging analyses showed that NERP-4 accelerated intracellular Ca2+ influx in MIN6 cells. NERP-4 potentiated glucose-stimulated insulin secretion (GSIS) from isolated mouse islets. Peripheral administration of NERP-4 increased plasma insulin level under glucose load in rats. NERP-4 is a novel regulator of GSIS.
