BRI Receives $2.2 Million to Study Critical Factor in Autoimmune Diseases

Benaroya Research Institute at Virginia Mason (BRI) received a $2.2 million federal research grant from the National Institute of Allergy and Infectious Diseases at the National Institutes of Health to investigate a key factor that plays a critical role in preventing autoimmunity and limiting immune-mediated inflammation. If scientists can find a way to manipulate or program this factor, it can be used in cellular therapy to help eliminate these diseases. This particular grant focuses on diseases such as a persistent mycobacterium tuberculosis infection, psoriasis, rheumatoid arthritis, Type 1 diabetes and multiple sclerosis.

"Autoimmune and immune-mediated diseases are a major public health challenge," says Daniel Campbell, PhD, Associate Member at BRI and Principal Investigator for the grant. "The immune system is like a finely-tuned engine. It works to eliminate bacteria, viruses and other infectious threats to our bodies. But sometimes it overreacts or underreacts. In this grant, I’m studying a particular type of cells that help maintain this balance and turn off the immune system when it overreacts. If we can understand how these cells put the brakes on the immune system, and how their activity is controlled during infection and autoimmunity, we may be able to develop individual therapies to help each patient with his or her specific disease situation."

Dr. Campbell is studying regulatory T cells, a group of white blood cells that regulate the immune system. Some regulatory T cells express a transcription factor, T-bet, that works with another factor called Foxp3 to maintain a balanced immune system. Dr. Campbell and his colleagues discovered that T-bet was critical for regulatory T cell function in certain immunological contexts. This finding was published in Nature Immunology in June 2009 and led to the recently awarded grant. With the new funding, Dr. Campbell is investigating more closely how T-bet and Foxp3 function together so their activities can be manipulated therapeutically to prevent or treat immune-mediated diseases.

Nearly 23.5 million Americans have an autoimmune disease. According to the National Institutes of Health, the annual health care costs for autoimmune diseases are $100 billion in the U.S. Autoimmune diseases are a top 10 cause of death for women and children. BRI’s overall research aims to block autoimmunity before damage occurs and to develop therapies to reverse disease by redirecting faulty immune systems so they won’t attack healthy tissues.

About Benaroya Research Institute

Benaroya Research Institute (BRI) is a world leader in human immune system research. BRI works to advance the science that will predict, prevent, reverse and cure immune system diseases like allergies, asthma, cancer, COVID-19 and autoimmune diseases. BRI accelerates discovery through laboratory breakthroughs in immunology that are then translated to clinical therapies. We believe that a breakthrough in one immune system disease can lead to progress against them all, and work tirelessly toward our vision of a healthy immune system for everyone. BRI is a world-renowned independent nonprofit research institute affiliated with Virginia Mason Franciscan Health and based in Seattle.
