The Immune Health Future, Today

by Christina Hernandez Sherwood

Breaking the code of the immune system could provide a new fundamental way of understanding, treating, and preventing every type of disease. Penn Medicine is investing in key discoveries about immunity and immune system function, and building infrastructure, to make that bold idea a reality.

Several members of the Penn Bioengineering Graduate Group feature in this story which originally featured in the Penn Medicine Magazine.

This grandfather lives with primary progressive multiple sclerosis (MS), an autoimmune disorder that he controls with a medicine that depletes his body of the type of immune cells that make antibodies. So while he has completed his COVID-19 vaccine course, his immune system function isn’t very strong—and the invitation has arrived at a time when COVID-19 is still spreading rapidly. 

You can imagine the scene as an older gentleman lifts a thick, creamy envelope from his mailbox, seeing his own name written in richly scripted lettering. He beams with pride and gratitude at the sight of his granddaughter’s wedding invitation. Yet his next thought is a sober and serious one. Would he be taking his life in his hands by attending the ceremony?

“In the past, all we could do was [measure] the antibody response,” says Amit Bar-Or, the Melissa and Paul Anderson President’s Distinguished Professor in Neurology at the Perelman School of Medicine, and chief of the Multiple Sclerosis division. “If that person didn’t have a good antibody response, which is likely because of the treatment they’re on, we’d shrug our shoulders and say, ‘Maybe you shouldn’t go because we don’t know if you’re protected.’” 

Today, though, Bar-Or can take a deeper dive into his patients’ individual immune systems to give them far more nuanced recommendations. A clinical test for immune cells produced in response to the COVID-19 vaccine or to the SARS-CoV-2 virus itself—not just antibodies—was one of the first applied clinical initiatives of a major new Immune Health® project at Penn Medicine. Doctors were able to order this test and receive actionable answers through the Penn Medicine electronic health record for patients like the grandfather with MS. 

“With a simple test and an algorithm we can have a very different discussion,” Bar-Or says. A test result showing low T cells, for instance, would tell Bar-Or his patient may get a meaningful jolt in immunity from a vaccine booster, while low antibody levels would suggest passive antibody therapy is more helpful. Or, the test might show his body is already well primed to protect him, making it reasonably safe to attend the wedding.

This COVID-19 immunity test is only the beginning. 

Physicians and scientists at Penn Medicine are imagining a future where patients can get a precise picture of their immune systems’ activity to guide treatment decisions. They are working to bring the idea of Immune Health to life as a new area of medicine. In labs, in complex data models, and in the clinic, they are beginning to make sense out of the depth and breadth of the immune system’s millions of as-yet-undeciphered signals to improve health and treat illnesses of all types. 

Penn Medicine registered the trademark for the term “Immune Health” in recognition of the potential impact of this research area and its likelihood to draw non-academic partners as collaborators in its growth. Today, at the south end of Penn’s medical campus, seven stories of research space are being added atop an office building at 3600 Civic Center Blvd., including three floors dedicated to Immune Health, autoimmunity, and immunology research.

The concept behind the whole project, says E. John Wherry, director of Penn Medicine’s Institute for Immunology and Immune Health (I3H), “is to listen to the immune system, to profile the immune system, and use those individual patient immune fingerprints to diagnose and treat diseases as diverse as immune-related diseases, cancer, cardiovascular disease, Alzheimer’s, and many others.”

The challenge is vast. Each person’s immune system is far more complex than antibodies and T cells alone. The immune system is made of multiple interwoven layers of complex defenders—from our skin and mucous membranes to microscopic memory B cells that never forget a childhood infection—meant to fortify our bodies from germs and disease. It is a sophisticated system that learns and adapts over our lifetimes in numerous ways, and it also falters and fails in some ways we understand and others that remain mysterious. And each person’s intricate internal battlefield is in some way unique.

The immune system is not just a set of defensive barricades, either. It’s also a potential source of deep insight about a person’s physiological functioning and responses to medical treatments.

“The immune system is sensing and keeping track of basically all tissues and all cells in our body all the time,” Wherry says. “It is surveying the body trying to clean up any invaders and restore homeostasis by maintaining good health.”

“Our goal is to essentially break the code of the immune system,” says Jonathan Epstein, executive vice dean of the Perelman School of Medicine and chief scientific officer at Penn Medicine. “By doing so, we believe we will be able to determine your state of health and your response to therapies in essentially every human disease.”

CAR T cell therapy pioneer Carl June, the Richard W. Vague Professor in Immunotherapy in the Perelman School of Medicine and director of the Center for Cellular Immunotherapies (CCI) at Penn Medicine’s Abramson Cancer Center, has been named a winner of the 2024 Breakthrough Prize in Life Sciences for the development of chimeric antigen receptor (CAR) T cell immunotherapy, a revolutionary cancer treatment approach in which each patient’s T cells are modified to target and kill their cancer cells. The invention sparked a new path in cancer care, harnessing the power of patients’ own immune systems, a once-elusive goal that brought fresh options for those who could not be successfully treated with conventional approaches.

Founded in 2012, the Breakthrough Prizes are the world’s largest science awards, with $3 million awarded for each of the five main prize categories. June is the sixth Breakthrough Prize laureate from Penn, which joins Harvard and MIT among the institutions whose researchers have been honored with the most Breakthrough Prizes.

“This award is not only a testament to Dr. June’s outstanding contributions to science, but also a shining example of the caliber of discoveries and research which Penn faculty set their sights upon,” said Penn President Liz Magill. “We are immensely proud to have Dr. June as a member of the Penn academic community, and we know that CAR T cell therapy is just the first chapter in an inspiring and lifesaving new era of medicine.”

June is internationally recognized for his role in pioneering the CAR T cell therapy, which led to the first FDA-approved personalized cellular therapy, for children and young adults with the blood cancer known as acute lymphoblastic leukemia, in August of 2017—a step which has spurred five additional approvals of the technique in other blood cancers. June joined Penn in 1999, building momentum for Penn to become a global hub for cell and gene therapy. Gene-modified T cells engineered in June’s lab to retrain a patient’s own immune cells to attack cancer were used in the first clinical trial of CAR T cell therapy in 2010. Some of the earliest children and adults treated have experienced long-lasting remissions of 10 years or more. In addition to the FDA approvals that have made the therapy commercially available to patients across the world, thousands more have benefited from clinical trials testing these transformative treatments, including for the treatment of solid tumors and even autoimmune diseases like lupus.

“Dr. June’s tireless commitment to advancing T cell immunotherapy research has been life-changing for many patients affected by cancer, who have lived longer, fuller lives, thanks to the discoveries made in his lab,” said J. Larry Jameson,executive vice president of the University of Pennsylvania for the Health System and dean of the Perelman School of Medicine. “We are proud to see one of Penn’s most esteemed scientists recognized for the impact of his foundational work to develop a new class of cancer immunotherapy treatment.”

Chasing the Mysteries of Microbiome Communication in Our Bodies

by Kelsey Geesler

When we hear about gut bacteria, we may think about probiotics and supplements marketed to help with digestion, about how taking antibiotics might affect our intestinal tract, or perhaps about trendy diets that aim to improve gut health.

But two researchers at Penn Medicine think that understanding the microbiome, the entirety of microbial organisms associated with the human body, might be the key to deciphering the fundamental mechanisms that make our bodies work. They think these microbes may work like a call center switchboard, making connections to help different organs, biological systems, and the brain communicate. Maayan Levy, and Christoph Thaiss, both assistant professors of microbiology at the Perelman School of Medicine, argue that the microbiome is instrumental to revealing how signals from the gastrointestinal tract are received by the rest of the body—which may hold the key to understanding inter-organ communication in general.

While the gut sends signals to all parts of the body to initiate various biological processes, the mechanisms underlying this communication—and communication between different organs involved in these processes—is relatively unknown.

“The more we learn about the role the microbiome plays in a wide range of diseases— from cancer to neurodegenerative diseases to inflammatory diseases—the more important it becomes to understand what exactly its role is,” says Thaiss. “And hopefully once we understand how it works, we can use the microbiome to treat these diseases.”

Levy and Thaiss joined the faculty at Penn Medicine after completing their graduate studies in 2018. Here, they continue to investigate the role of the microbiome in various biological processes.

In his lab, Thaiss focuses on the impact of the microbiome on the brain. He recently identified species of gut-dwelling bacteria that activate nerves in the gut to promote the desire to exercise. Most recently, Thaiss published a study that identified the cells that communicate psychological stress signals from the brain to the gastrointestinal tract, and cause symptoms of inflammatory bowel disease.

Meanwhile, in her lab, Levy examines how the microbiome influences the development of diseases, like cancer, and other conditions throughout the body.

A recent publication authored by Levy suggested that the ketogenic diet (high fat, low carbohydrate) causes the production of a metabolite called beta-hydroxybutyrate (BHB), that suppresses colorectal cancer in small animal models.

Now, Levy is collaborating with Bryson Katona, an assistant professor of Medicine in the division of gastroenterology who specializes in gastrointestinal cancers, to investigate whether BHB has the same effect in patients with Lynch syndrome, which causes individuals to have a genetic predisposition to many different kinds of cancer, including colon cancer. These efforts are part of a growing emphasis at Penn on finding methods to intercept cancer in its earliest stages.

“It’s remarkable that we were able to quickly take the findings from our animal models and rapidly design a clinical trial,” Levy says. “One of the most exciting aspects of our work is not only making discoveries about how our bodies work on a biological level, but then being able to work with the world’s leading clinical experts to translate these discoveries into therapies for patients.”

Further, studies led by Levy and Thaiss often utilize human samples and data from the Penn Medicine BioBank, to validate animal model findings in the tissue of human patients suffering from the diseases which they are investigating.

While Levy and Thaiss pursue different research interests with their labs, they also collaborate often, building on their previous research into what the microbiome does, and its role in the biological processes that keep us healthy. Their long-term goal is to learn about the mechanisms by which the gastrointestinal tract influences disease processes in other organs to treat various diseases of the body using the gastrointestinal tract as a noninvasive entry point to the body.

“Some of the most common and devastating diseases in humans—like cancer or neurodegeneration—are difficult to treat because they are no existing therapies that can reach the brain,” says Thaiss. “If we can understand how the gastrointestinal tract interacts with other organs in the body, including the brain, we might be able to develop treatments that ‘send messages’ to these organs through the body’s natural communication pathways.”

“Obviously there is a lot more basic biology to be uncovered before we get there,” adds Levy. “Most importantly, we want to map all the different routes by which the gastrointestinal tract interacts with the body, and how that communication happens.”

CAR T Cell Therapy Reaches Beyond Cancer

Penn Medicine researchers laud the early results for CAR T therapy in lupus patients, which point to broader horizons for the use of personalized cellular therapies.

Penn Medicine’s Carl June and Daniel Baker.

Engineered immune cells, known as CAR T cells, have shown the world what personalized immunotherapies can do to fight blood cancers. Now, investigators have reported highly promising early results for CAR T therapy in a small set of patients with the autoimmune disease lupus. Penn Medicine CAR T pioneer Carl June and Daniel Baker, a doctoral student in cell and molecular biology in the Perelman School of Medicine, discuss this development in a commentary published in Cell.

“We’ve always known that in principle, CAR T therapies could have broad applications, and it’s very encouraging to see early evidence that this promise is now being realized,” says June, who is the Richard W. Vague Professor in Immunotherapy in the department of Pathology and Laboratory Medicine at Penn Medicine and director of the Center for Cellular Immunotherapies at the Abramson Cancer Center.

T cells are among the immune system’s most powerful weapons. They can bind to, and kill, other cells they recognize as valid targets, including virus-infected cells. CAR T cells are T cells that have been redirected, through genetic engineering, to efficiently kill specifically defined cell types.

CAR T therapies are created out of each patient’s own cells—collected from the patient’s blood, and then engineered and multiplied in the lab before being reinfused into the patient as a “living drug.” The first CAR T therapy, Kymriah, was developed by June and his team at Penn Medicine, and received Food & Drug Administration approval in 2017. There are now six FDA-approved CAR T cell therapies in the United States, for six different cancers.

From the start of CAR T research, experts believed that T cells could be engineered to fight many conditions other than B cell cancers. Dozens of research teams around the world, including teams at Penn Medicine and biotech spinoffs who are working to develop effective treatments from Penn-developed personalized cellular therapy constructs, are examining these potential new applications. Researchers say lupus is an obvious choice for CAR T therapy because it too is driven by B cells, and thus experimental CAR T therapies against it can employ existing anti-B-cell designs. B cells are the immune system’s antibody-producing cells, and, in lupus, B cells arise that attack the patient’s own organs and tissues.

FDA Approves Penn Pioneered CAR T Cell Therapy for Third Indication

The U.S. Food and Drug Administration has expanded its approval for Kymriah, a personalized cellular therapy developed at the Abramson Cancer Center, this time for the treatment of adults with relapsed/refractory follicular lymphoma who have received at least two lines of systemic therapy. “Patients with follicular lymphoma who relapse or don’t respond to treatment have a poor prognosis and may face a series of treatment options without a meaningful, lasting response,” said Stephen J. Schuster, the Robert and Margarita Louis-Dreyfus Professor in Chronic Lymphocytic Leukemia and Lymphoma in the Division of Hematology Oncology. It’s the third FDA approval for the “living drug,” which was the first of its kind to be approved, in 2017, and remains the only CAR T cell therapy approved for both adult and pediatric patients.

“In just over a decade, we have moved from treating the very first patients with CAR T cell therapy and seeing them live healthy lives beyond cancer to having three FDA-approved uses of these living drugs which have helped thousands of patients across the globe,” said Carl June, MD, the Richard W. Vague Professor in Immunotherapy in the department of Pathology and Laboratory Medicine in Penn’s Perelman School of Medicine and director of the Center for Cellular Immunotherapies in the Abramson Cancer Center and director of the Parker Institute for Cancer Immunotherapy at Penn. “Today’s news is new fuel for our work to define the future of cell therapy and set new standards in harnessing the immune system to treat cancer.”

Research from June, a member of the Penn Bioengineering Graduate Group, led to the initial FDA approval for the CAR T therapy (sold by Novartis as Kymriah) for treating acute lymphoblastic leukemia (ALL), one of the most common childhood cancers.

Penn Anti-Cancer Engineering Center Will Delve Into the Disease’s Physical Fundamentals

by Evan Lerner

A colorized microscope image of an osteosarcoma shows how cellular fibers can transfer physical force between neighboring nuclei, influencing genes. The Penn Anti-Cancer Engineering Center will study such forces, looking for mechanisms that could lead to new treatments or preventative therapies.

Advances in cell and molecular technologies are revolutionizing the treatment of cancer, with faster detection, targeted therapies and, in some cases, the ability to permanently retrain a patient’s own immune system to destroy malignant cells.

However, there are fundamental forces and associated challenges that determine how cancer grows and spreads. The pathological genes that give rise to tumors are regulated in part by a cell’s microenvironment, meaning that the physical push and pull of neighboring cells play a role alongside the chemical signals passed within and between them.

The Penn Anti-Cancer Engineering Center (PACE) will bring diverse research groups from the School of Engineering and Applied Science together with labs in the School of Arts & Sciences and the Perelman School of Medicine to understand these physical forces, leveraging their insights to develop new types of treatments and preventative therapies.

Supported by a series of grants from the NIH’s National Cancer Institute, the PACE Center is Penn’s new hub within the Physical Sciences in Oncology Network. It will draw upon Penn’s ecosystem of related research, including faculty members from the Abramson Cancer Center, Center for Targeted Therapeutics and Translational Nanomedicine, Center for Soft and Living Matter, Institute for Regenerative Medicine, Institute for Immunology and Center for Genome Integrity.

Dennis Discher and Ravi Radhakrishnan

The Center’s founding members are Dennis Discher, Robert D. Bent Professor with appointments in the Departments of Chemical and Biomolecular Engineering (CBE), Bioengineering (BE) and Mechanical Engineering and Applied Mechanics (MEAM), and Ravi Radhakrishnan, Professor and chair of BE with an appointment in CBE.

Discher, an expert in mechanobiology and in delivery of cells and nanoparticles to solid tumors, and Radhakrishnan, an expert on modeling physical forces that influence binding events, have long collaborated within the Physical Sciences in Oncology Network. This large network of physical scientists and engineers focuses on cancer mechanisms and develops new tools and trainee opportunities shared across the U.S. and around the world.

Alumni Spotlight: Danielle Rossi

Danielle Rossi (M.S.E. 2018)

Danielle Rossi earned her M.S.E. in Bioengineering in December 2018 and is now a R&D Leadership and Development Program Engineer with Johnson & Johnson Medical Devices. Here she reminisces about her research opportunities at Penn and her fond memories of Philly.

“When I first started at Penn, I was amazed by all of the opportunities to learn, to challenge myself, to network, and to innovate. My time at Penn was filled with interesting classes, dedicated faculty, challenging problems to solve, and collaboration. From writing a mock NIH research grant for a tissue engineered Intervertebral Disk in BE 553, to designing an electromechanical device controlled with muscle movement in BE 570, to writing up a business plan and pitching to investors in EAS 546, every new day came with a new venture.

On top of the exciting classes and projects, Penn has numerous research labs and healthcare facilities so that students can apply their skills to real-world problems. While I was a student, I had the opportunity to work at the Abramson Cancer Center in the Cancer Risk Evaluation Program. The program focused on patient risk evaluations, including genetic testing for certain cancers such as breast, ovarian, and sarcoma. This exposed me to the healthcare environment and gave me a new perspective on preemptive medicine.

During my free time, I loved to tour the historically and culturally rich city of Philadelphia. I have the fondest memories of exploring the city with my BE friends and storming the Philly streets when the Eagles won the Super Bowl!

While at Penn, I was sure to utilize Career Services to help me spruce up my resume and interview skills. I was lucky enough to meet with Johnson & Johnson Medical Devices at a Penn career fair and was offered a spot in the R&D Leadership and Development Program. The program allows me to rotate through three different J&J Medical Device companies as an R&D Engineer to gain exposure to new product development, mechanical design, computational modeling, manufacturing, design quality and more. ”
