The Jacobson lab focus is on the mechanisms that influence pancreatic islet calcium homeostasis and hormone secretion under physiological and diabetic conditions. The goal is to identify pathways that can be therapeutically targeted to reduce pancreatic islet dysfunction and restore euglycemia in patients with diabetes. The primary models employed in these projects include: human islets, rodent islets, pancreatic slices and cultured cells. The research utilizes cutting edge approaches in molecular biology, fluorescent microscopy (both widefield and confocal), electrophysiology, biochemistry, virus mediated expression of genetically encoded indicators for calcium and membrane potential, and transgenic models.
