Carter Immunology Center marks 25 years of changing how we approach disease

November 02 2016

Researchers at the School of Medicine have developed an experimental vaccine to battle melanoma, a deadly form of skin cancer. It’s an example of cutting-edge immunotherapy, the harnessing of the immune system’s power to battle disease. But it also represents a fulfillment of potential UVA recognized 25 years ago.

In 1991, with financial support from businessman Beirne B. Carter, UVA established the Beirne Carter Center for Immunology Research . In those days, the notion that there could be a vaccine for cancer would have drawn scoffs. There wasn’t even agreement in the scientific community that the human body could have an immune response to cancer. It wasn’t an infection, wasn’t the result of some bacterium, virus or parasite. So why would the immune system be involved?

Turns out it was. And in the 25 years since the center’s founding, the field of immunology has exploded, becoming one of the hottest areas in medical research. Its applications are far-reaching: not just cancer but multiple sclerosis, AIDS, allergies, diabetes, autoimmune disorders – an endless list of medical conditions that have benefited from a new way of thinking about the immune system. It represents nothing short of a revolution in how we approach, understand and treat disease, and UVA’s Carter Center for Immunology Research has been in the thick of it all.

Groundbreaking discoveries

“It’s been a tremendous period,” said Victor H. Engelhard, PhD , the center’s director. “It coincided with immunology expanding as a discipline and immunology reaching to so many disease states. But we also have learned a tremendous amount about how the immune system works in more fundamental ways. So there’s this back-and-forth between the basic discoveries and the translational and clinical opportunities, and so the center has grown in the sense of encompassing more elements of immunology, but it’s also grown in terms of applying the scientific understandings and treating people with disease.”

Today the Beirne Carter Center has more than 40 members, up from about five when it began. Its work has drawn headlines around the world, such as the textbook-changing discovery last year by center member Jonathan Kipnis, PhD , that the brain and immune system are directly connected by vessels long thought not to exist. (Prior to that finding, the brain was thought to be “immune privileged,” meaning it lacked that direct connection.) The discovery could have profound implications for neurological conditions such as autism, multiple sclerosis and Alzheimer’s disease.

But that’s just the tip of the iceberg. Center members are taking on everything from hepatitis C to disease and malnutrition in the developing world. They are targeting autoimmune diseases, such as lupus, and they are advancing our understanding of how to treat and prevent cardiovascular disease. Their efforts have shed light on the fundamental workings of our immune system, from identifying an unknown molecule that plays a vital role in initiating immune responses to helping prove the existence of “regulatory T cells” critical for preventing autoimmune diseases, allergy and transplant tissue rejection. The center’s research could lead to new ways to battle pneumonia, stop peanut and meat allergies, even prevent deadly flu infections. The scope of the work is vast, and its potential impact tremendous.

Fostering collaboration

One of the center’s greatest strengths, Engelhard said, is that it brings together researchers across disciplines to make discoveries and then apply those discoveries, such as Engelhard’s collaboration on the melanoma vaccine with Craig L. Slingluff Jr., MD , of the UVA Cancer Center . This shared journey of discovery creates excitement and builds momentum. “You can’t legislate it, right?” said Engelhard, of UVA’s Department of Microbiology, Immunology and Cancer Biology. “You have to create opportunities in which people come together.”

His collaboration with Slingluff highlights the advantages of the approach and speaks to the importance of the Carter Center’s research. “With cancer vaccines, you’re treating patients with cancer and not inoculating them against the cancer, and so to understand how to do that requires … an understanding of how the immune system works fundamentally, and it requires an understanding of the status of the immune system in the context of the patient with cancer,” he said. “What’s happened to their immune system that renders them maybe poised to control cancer but unable to do so?  How do you change that state?”

Answering those sorts of questions is at the heart of what the Carter Center does. The field of immunology has changed dramatically since the center was founded, but the Carter Center’s fundamental mission of discovery has not. “The advances that we’ve had over the 25 years of this center’s existence have really influenced how the center has developed, because we’ve gone from simple understandings to increasingly complex understandings. But I think we’re also poised to really bring those understandings much more into the treatment of disease,” Engelhard said. “I think we now have an extraordinary number of tools that can be developed therapeutically. That’s a tremendous opportunity.”
