Innovation Fund Spotlight: State-of-the-Art Genome Editing To Understand Disease and Develop New Therapies

For more than 20 years, Benaroya Research Institute (BRI) President Jane Buckner, MD, has had some theories about gene changes and cells that might play a role in autoimmune disease. But to actually prove these theories, she needs concrete evidence that one tiny change in a single gene can start the chain reaction that leads to autoimmune disease.

Until recently, that technology didn’t exist. Now, it does.

It has a long and detailed scientific name: CRISPR-Cas9-based genome engineering using adeno-associated virus (AAV) vectors. And she and Oliver Harrison, DPhil, are working to get it up and running at BRI, thanks to BRI’s latest Innovation Fund grant. This fund awards two grants per year, enabling teams of BRI scientists to implement innovative technologies. After the initial project, the technology becomes available to scientists across BRI.

“When I started my career, I never could’ve imagined a technology that would allow us to change individual genes inside of human cells in the lab,” Dr. Buckner says. “Having this technology at BRI to use in our everyday research is incredibly empowering. It enables us to study the finite details of the immune system and rapidly explore new ideas to engineer new therapies.”

Dr. Buckner will use this genome engineering technology to study human T cells and explore new treatments for type 1 diabetes (T1D) and other autoimmune diseases. Dr. Harrison will use it to develop preclinical models to study T cells and B cells to ask questions about inflammatory bowel diseases like ulcerative colitis (UC) and Crohn’s disease.

We asked Dr. Buckner and Dr. Harrison some questions about their Innovation Fund project. Here’s what they had to say.

Tell us more about the tool you’ll be implementing. What is it and why is it exciting?

Dr. Buckner: Broadly, this new genome engineering tool will allow us to create cells or models that mimic autoimmune diseases to better understand how genetic changes lead to these conditions. It also enables us to engineer immune cells, which can be designed to slow down the immune system’s attack in autoimmune diseases.

This type of genome engineering is exciting because it allows us to make very specific changes within human T cells – in a lab setting. Then, we can see if those changes impact how T cells talk to other cells and if that change might make a cell stop attacking healthy tissue or start attacking cancer cells. Asking these questions in the lab provides important insight into how immune system diseases happen, and how we can stop them.

What questions will this tool help you answer?

Dr. Harrison: My team plans to use this technology to learn more about how immune cells called B and T cells interact with gut microbes (the bacteria that live in your gut). We are hoping to learn more about what goes awry with those interactions in people with Crohn’s disease and UC.

We know that everybody develops immune responses to certain bacteria within their gut, and these are important for intestinal health and repair. However, in people with Crohn’s disease and UC, these responses are excessive, and are believed to contribute to inflammation within the intestine. We’re using genome engineering to create new ways to track T and B cell responses to gut microbes, allowing us better ways to understand how the excessive response occur, and to better model IBD and how we may prevent or cure these diseases in the future.

Dr. Buckner: One of my lab’s core focuses is engineering regulatory T cells as a new treatment for type 1 diabetes. So far, our partners at Seattle Children’s Research Institute have done the genome editing for the project. Once we have this tool up and running at BRI, we believe we can use it to adapt the approach we developed for T1D to study rheumatoid arthritis, lupus, multiple sclerosis, and maybe even allergies — and do that fairly quickly.

We’re also interested in using genome editing to see if we can modify cells to do certain jobs — such as improving their ability to kill cancer cells or slow down their attack in autoimmune disease.

How might this technology benefit other scientists at BRI?

Dr. Harrison: My hope is that this technology becomes another “workhorse” tool like flow cytometry or imaging. Scientists across BRI will be able to use it every day to answer a wide range of questions.

Another way it can be widely applied is through “reverse translational” research. This is a type of research where we take data from a study in people and bring it back to the lab to learn more about something we don’t understand — like why a treatment worked well for one patient but not another, or why certain side effects happen. We’ll be able to create models that allow us to look at certain genes or T cell receptors to better understand what’s happening in people with autoimmunity.

Why is philanthropy to support new research avenues and technologies important?

Dr. Buckner: BRI’s mission is to predict, prevent, reverse and cure immune system diseases — and we want to do that as fast as we can. Philanthropy to support new tools and innovative approaches accelerates the pace of discovery and moves us closer to prevention and cures.

In terms of BRI’s Innovation Fund, philanthropy helps provide opportunities for our scientists to work together in ways that they otherwise might not be able to. The grants fund a project for two investigators, but they ultimately lift up all scientists at BRI. This collaboration includes junior investigators, and provides a great opportunity to develop their skills and become the next leaders at BRI. One of the junior scientists in my lab, Arpit Mishra, PhD, is playing a crucial role in this study by working with both myself and Dr. Harrison. He’s the link between our two labs and plays a very important role in making this work happen.

Traditional funding sources like the National Institutes of Health (NIH) don’t typically support new tools and technologies, so philanthropy is a crucial funding source to fill this gap. NIH funding for biomedical research as a whole is uncertain right now, which makes philanthropic support more important than ever.

What message would you have for donors who support this fund?

Dr. Harrison: I want to express my gratitude for the people who invest in the Innovation Fund. It allows us to bring tools to BRI that keep our institute on the forefront of scientific research.

Your support is truly making a difference in what we can do and the speed at which we can do it. We’re already seeing some very exciting innovations come out of past Innovation Fund projects — and I know that there will be many more.
