UIC: New Treatment Option For Type 1 Diabetes Brings Research Funding

Posted by Rebecca Partridge on Mon, Aug 15, 2016

The University of Illinois at Chicago received a two-year, $475,000 grant to study a new treatment for type 1 diabetes that might help protect the pancreas. This promising new treatment would involve using two protein molecules to reduce the damage caused by the body’s autoimmune response.  The research led by Dr. Bellur S. Prabhaker, Professor of Microbiology and Immunology at UIC, could eventually free many diabetes patients from the rigors of daily insulin injections.

What’s new about this treatment?

To understand that, you need to understand how type 1 diabetes works.  T1D is an autoimmune disease. Usually, the immune system’s T cells identify and destroy harmful bacteria and viruses. However, sometimes T cells will misidentify the body’s own cells as foreign.  When this happens in healthy people, regulatory T cells repress these errant “effector” T cells and keep them from causing much harm.  With type 1 diabetes, these effector T cells are able to attack and damage the pancreas, which is the organ responsible for insulin production. This happens because people with T1D don’t produce enough regulatory T cells to stop the assault.

Dr. Prabhaker says, “The holy grail for type 1 diabetes researchers has been to figure out a way to amplify the number of regulatory T cells without also amplifying effector T cells.”

Until this new study, attempts to amplify the production of regulatory T cells have met with only limited success. They either also amplified the production of effector T cells or they have been too expensive, cumbersome, and required frequent repetition. By contrast, according to the UIC’s News Center, Dr. Prabhaker’s research has demonstrated that “regulatory T cells can be amplified selectively using two specialized protein molecules called OX40L and JAG1. The molecules bind to receptors only found on regulatory T cells, and together spur the cells to multiply.” It goes on to explain that, “Experimental mice with type 1 diabetes that were treated with the mouse versions of the two molecules were found to have more working regulatory T cells, more intact islet cells, and normal blood sugar levels.”

What’s next?

The grant from the JDRF, Juvenile Diabetes Research Foundation, will be used to conduct further testing at the UIC College of Medicine.  Researchers will study the ability of Human OX40L and JAG1 to amplify regulatory T cells selectively.  “If we can show that the two human proteins can selectively restore healthy numbers of functional regulatory T cells, then we may have a treatment for type 1 diabetes that requires an injection every couple of weeks instead of insulin injections multiple times a day,” Prabhakar said. 

Why is this important?

Because there are 1.25 million people in the United States with Type 1 diabetes.  According to the JDRF website, 110 new cases are diagnosed every day.  And though type 1 diabetes used to be known as Juvenile Diabetes because it was most often diagnosed in children, now an equal number of children and adults are diagnosed every day. In fact, nearly 85 percent of people living with the disease are over age 18, and even when the condition is managed, there are still long term health risks associated with diabetes. Complications include nerve and retina damage, kidney failure, heart attack, stroke, blindness and amputation. Protecting the pancreas, so the body can continue to produce its own insulin, would help reduce health risks that insulin treatment alone does not address.
