Dr. Jeffery Sivert Tessem's lab focuses on understanding how specific proteins can increase the mass of functional insulin-producing beta cells, which is crucial in treating diabetes. By studying the role of a protein called Nr4a1, the lab aims to discover new ways to enhance beta cell function and proliferation, potentially leading to better therapies for individuals with Type 1 and Type 2 diabetes. Their research could help address significant health challenges related to diabetes management.
