A new research initiative is set to explore the cellular mechanisms that drive arthritis and the reasons behind its complex and often unpredictable progression. The study, led by Dr. Etienne Masle-Farquhar, a Research Officer at the Garvan Institute of Medical Research, seeks to enhance treatment effectiveness and monitoring for arthritis patients, focusing on the role of rogue cells and genetic mutations.
Dr. Masle-Farquhar, the Chief Investigator of Blood and Bone: A Multiomic Study of Arthritic Joints, leads a team of multidisciplinary researchers aiming to uncover the cellular and molecular processes that fuel the development and worsening of arthritic diseases. Their goal is to develop evidence-based guidance to help clinicians select the most appropriate treatments and predict their effectiveness.
“We hope to identify the specific cellular and molecular mechanisms that drive the progression of arthritis, which could provide clinicians with better tools for treatment selection and efficacy prediction,” Dr. Masle-Farquhar said.
Funding and Clinical Impact
The project has been awarded $500,000 in funding over three years from the Office for Health and Medical Research through an Early-Mid Career Grant. Dr. Masle-Farquhar emphasized the importance of this support in building a sustainable clinical network, expanding the biobank, and fostering the development of cutting-edge experiments and research. “This grant is pivotal for securing the future of our arthritis biobanking and research program, ensuring its position as a long-term hub in New South Wales,” he noted.
Arthritis: A Complex Disease
Arthritis remains a leading cause of chronic pain, affecting millions worldwide. Rheumatoid arthritis, the most common autoimmune disorder, impacts over 500,000 Australians, while osteoarthritis affects over two million Australians and 500 million people globally. Dr. Masle-Farquhar noted that the disease disproportionately affects older adults, people in rural areas, and Aboriginal communities, with certain forms of arthritis also posing a significant burden on women, children, and young men in their 20s to 30s.
Beyond joint pain, arthritis can lead to stiffness, swelling, and reduced mobility, affecting not only physical health but also mental wellbeing and overall quality of life. The disease is also linked to a range of systemic complications, including heart disease, lung disease, infections, osteoporosis, and cognitive decline.
Investigating Rogue Cells and Genetic Mutations
A key focus of the study is the role of rogue immune cells, which may contribute to the onset and progression of arthritis. “Our research aims to determine whether rogue cells—those that behave abnormally—play a significant role in initiating or worsening arthritis, resistance to treatments, and the development of systemic complications,” Dr. Masle-Farquhar explained.
The study will also explore the potential impact of acquired mutations in DNA. These mutations, which are not inherited but instead arise randomly within cells, may offer insights into the unpredictable onset of arthritis and the variability of treatment responses.
Building a Comprehensive Biobank
To support this research, the team is establishing a unique biobank to store clinical data and biological samples from arthritis patients. The biobank will include blood, saliva, synovial tissue, synovial fluid, bone marrow, and bone samples, which are collected from patients at several hospitals, including St Vincent’s Private Clinic, St Vincent’s Public Hospital, and Westmead Hospital. These samples will be stored at the Garvan Institute of Medical Research for future analysis.
Advancing Research with Multiomics Technology
The research will utilize “multiomics,” a cutting-edge approach that combines data from DNA, RNA, epigenetic changes, and proteins to provide a comprehensive picture of the genetic and molecular factors driving arthritis. Techniques like single-cell genome sequencing, which analyzes the genetic information of individual cells, will enable researchers to identify rogue cells and uncover the mechanisms behind arthritis development.
“The integration of these technologies gives us unprecedented power to pinpoint the specific cells or molecules responsible for arthritis, or those that could serve as biomarkers for the disease,” said Dr. Masle-Farquhar. This data could eventually help clinicians predict which patients are likely to respond to specific treatments or experience flare-ups, chronic pain, or other complications linked to arthritis.
In the long term, the research aims to improve the monitoring, diagnosis, and treatment of arthritis, paving the way for more personalized and effective therapies that could significantly enhance patient outcomes.
