Endocrinology Researchers Uncover New Hope for Treating Type 2 Diabetes

Dr. Jerrold OlefskyDr. Jerrold M. Olefsky and colleagues have reported a discovery that suggests a new way to treat obesity-related insulin resistance and Type 2 diabetes.

In a laboratory study, they found that insulin resistance could be reversed by lowering the amount of adipose tissue macrophages (ATMs) in tissue.

ATMs normally help fight infection, but in obesity they accumulate in fat tissue and can become triggers for inflammation. The inflammation is a factor in the development of insulin resistance and Type 2 diabetes.

Jerrold M. Olefsky, M.D., is Distinguished Professor of Medicine in the Division of Endocrinology and Metabolism and Associate Dean for Scientific Affairs. Co-leader of the study is Jaap Neels, Ph.D., a former UCSD colleague.
