HARNESSING AI TO PREVENT RHEUMATOID ARTHRITIS
The Promise of AI in RHEUMATOID ARTHRITIS RESEARCH
Rheumatoid Arthritis (RA) is a chronic autoimmune disease that affects approximately 18 million people worldwide, with 1.5 million of those cases in the United States. The condition is more prevalent in women, with nearly three times as many women affected as men. While current treatments can reduce inflammation and provide relief, there are no effective preventive measures or cures. This is where the groundbreaking work of Fan Zhang, PhD, enters the picture.
As an assistant professor in the University of Colorado Department of Medicine’s Division of Rheumatology and an affiliate of the Department of Biomedical Informatics at CU Anschutz Medical Campus, Zhang is at the forefront of using artificial intelligence (AI) to combat RA. Her research focuses on developing computational machine learning methods to predict the onset of RA in specific patients, which could lead to targeted interventions and early disease prevention.
Bridging Data Science and Translational Medicine
Zhang’s interdisciplinary approach bridges data science and translational medicine, leveraging large-scale clinical and preclinical single-cell datasets to identify new and more accurate markers for RA prediction. Her team analyzes data on genetics, genomics, epigenetics, protein, and other factors from individual cells over time, using a technique known as single-cell multi-modal sequencing.
This cutting-edge work aims to identify key immunological changes that could serve as biomarkers for RA onset, ultimately leading to improved prevention strategies. While Zhang acknowledges that reliable markers are "still a ways off," her ongoing research shows promising results and significant potential.
There have been fewer studies into developing preventive strategies and identifying which healthy people are at risk of developing RA in the next couple of years. That’s much more challenging. She thinks to focus on enhancing disease prediction to enable early disease prevention.
Pioneering Research and Funding Success
Zhang’s work has garnered significant recognition, including a highly competitive grant from the Arthritis Foundation to further her research. Her recent paper, "Deep immunophenotyping reveals circulating activated lymphocytes in individuals at risk for rheumatoid arthritis," published in The Journal of Clinical Investigation, documents the latest advancements in her research.
This publication, supported by a National Institutes of Health (NIH) grant, highlights the significant differences in specific immune cells, particularly T cell subtypes, in individuals at risk of developing RA. These findings could pave the way for new preventive strategies, although Zhang stresses the need for even larger and more geographically diverse datasets to validate these results.
Zhang is the corresponding author of this publication, with her lab’s postdoctoral fellow, Jun Inamo, and rheumatology colleagues Kevin Deane and V. Michael Holers also contributing as authors. This collaborative effort is part of a larger preclinical trial called StopRA, which aims to enhance our understanding of the progression from preclinical RA to symptomatic disease.

The diagnostic techniques reported by Zhang and her colleagues were able to predict Mark’s subsequent diagnosis with rheumatoid arthritis long before he even knew about it.
Mark is a 52-year-old art teacher, and a few years ago, a research + project with Fan Zhang’s lab approached him. Mark displayed none of the symptoms of arthritis. Throughout his day-to-day activities, especially his involvement in the arts, these robust diagnostic checks helped the team understand that Mark might develop severe symptoms of rheumatoid arthritis long before he even felt them. This enabled the medical team to utilize targeted intervention while they were effective. In the Rodriguez Case Study, the researchers analyzed Mark’s RNA and protein cells through advanced systems to identify promising immune markers in concentration. All this was part of and credit goes to the NIH funded grant study, “Deep immunophenotyping reveals circulatory activated lymphocytes in individuals at risk for rheumatoid Arthritis.”
Zhang’s multidisciplinary research and her team’s efforts at the CU Anschutz Medical Campus have simplified the process of incorporating AI in such uses. This multidisciplinary course helps Mark feel secure and confident in his arthritis management strategies while allowing the tech-advancements to progress further.
