Insulin Cells: Solo Functionality
- Geneva - Scientists at the University of Geneva (UNIGE) are challenging established beliefs about the role of pancreatic cells in diabetes.
- The conventional understanding was that beta cells required the support of alpha, delta, and gamma cells to function correctly.
- Pedro Herrera, a professor at the UNIGE Faculty of Medicine, and his team previously discovered the ability of pancreatic cells to adapt their function.
News from Geneva upends diabetes dogma: insulin cells might be able to function solo. UNIGE researchers discovered a new insight: beta cells can effectively manage blood sugar levels without the support of other pancreatic cells. the research found that mice with only beta cells showed superior glycemic regulation and substantially improved insulin sensitivity. This exciting finding challenges long-held beliefs about the role of other pancreatic cells and opens doors for novel diabetes treatments. Marta Perez Frances’ team eliminated non-beta cells and found the opposite of what they expected. The mice with beta cells only were healthier, challenging old understandings regarding the need for balance within hormonal systems. Researchers are delving deeper, seeking to convert non-beta cells.

Geneva Research Challenges Diabetes Dogma on pancreatic Cell Role
Geneva – Scientists at the University of Geneva (UNIGE) are challenging established beliefs about the role of pancreatic cells in diabetes. Their research indicates that beta cells, responsible for insulin production, can effectively regulate blood sugar levels even without the presence of other hormone-producing cells in the pancreas.
The conventional understanding was that beta cells required the support of alpha, delta, and gamma cells to function correctly. However, the UNIGE team’s findings, published in Nature Metabolism, demonstrate that adult mice with pancreases containing only beta cells exhibited superior glycemic regulation and insulin sensitivity compared to standard animals.
Pedro Herrera, a professor at the UNIGE Faculty of Medicine, and his team previously discovered the ability of pancreatic cells to adapt their function. If beta cells are lost, other endocrine cells can begin producing insulin. The current study explored the impact of eliminating all non-beta cells.
Marta Perez Frances, a researcher in Herrera’s lab, explained that they selectively eliminated non-beta cells in adult mice. “Surprisingly, not only were our mice perfectly capable of managing their blood sugar levels effectively, but they were even healthier than the control mice!” she said.
The mice with only beta cells showed improved insulin sensitivity, even when subjected to a high-fat diet or tested for insulin resistance, key indicators of diabetes. Herrera noted that the body adapts by recruiting hormonal cells from outside the pancreas to compensate for the reduction in other pancreatic hormones. He emphasized, “This clearly shows that non-beta cells of the pancreatic islets are not essential for maintaining glycemic balance.”
What’s next
Researchers are now focused on identifying molecules that can induce and amplify the conversion of non-beta cells into insulin-producing cells. Another approach involves differentiating stem cells in vitro to create new beta cells for transplantation. Herrera believes that focusing on insulin cells could lead to important advancements in diabetes treatment.
