Boosting beta cells to treat type 2 diabetes

Posted by in categories: biotech/medical, health

Researchers at Weill Cornell Medicine have uncovered a novel route to stimulate the growth of healthy insulin-producing pancreatic beta cells in a preclinical model of diabetes. The findings hold promise for future therapeutics that will improve the lives of individuals with type 2 diabetes—a condition that affects more than half a billion people worldwide.

This study, published in the Journal of Clinical Investigation on Sept. 15, demonstrated that activating a pathway to promote not only expanded the population of insulin-producing cells, but surprisingly, it also enhanced the cells’ function.

“That’s reassuring because there is a long-standing belief in the field that proliferation can lead to ‘de-differentiation’ and a loss of cell function,” said study senior author Dr. Laura Alonso, chief of the division of endocrinology, and metabolism, director of the Weill Center for Metabolic Health, and the E. Hugh Luckey Distinguished Professor in Medicine at Weill Cornell Medicine. “Our result flies in the face of that dogma and suggests if we can find a way to trigger replication of the in the body, we won’t impair their ability to produce and secrete insulin.”
