Anne-Marie Malfait, MD, PhD is an Associate Professor in the Department of Biochemistry and Section of Rheumatology at Rush University Medical Center. Dr. Malfait received her medical and graduate degrees from the University of Ghent, Belgium. She completed her Postdoctoral fellowship at the Kennedy Institute of Rheumatology, Imperial College, London. From 2001 - 2009, she worked as a senior principal investigator in the pharmaceutical industry, first at Pharmacia, then Pfizer.

Dr. Malfait is a member of The American College of Rheumatology,the International Association for the Study of Pain, the Osteoarthritis Research Society International and the Orthopaedic Research Society. Her research is focused on joint disease,particularly osteoarthritis (please see www.annemariemalfait.com), including:

  • Mechanisms of pain generation in osteoarthritis.
  • Development of chondroprotective drugs, including intra-articular treatment modality

She has received research funding from the NIH, the Arthritis Foundation, the Rush Translational Scientific Consortium.

Research Interest

Osteoarthritis (OA), the most common joint disorder, is characterized by a range of structural changes in all joint tissues, including cartilage, subchondral bone, menisci, synovial lining, ligaments, and periarticular muscle. The main concern of the OA patient is disability caused by functional limitations and, foremost, pain. Understanding the molecular basis of OA pain represents a major knowledge gap in both basic and translational science.

There is no simple correlation between pain symptoms and structural changes in the joint. We have mouse models and genetically modified mice available that will allow us to address whether matrix remodeling in OA joint tissues will lead to changes in nociceptors in the joint and affected dorsal root ganglia, ultimately resulting in chronic pain. The goal is to understand these pathways in the murine DMM (destabilization of the medial meniscus) model, which may lead to the development of (1) biomarkers for pain, (2) novel targets, and (3) new therapies.

We are forging collaborations with researchers with expertise in neuroscience, biomarkers and pain research, as well as with scientists in the private sector. Our group is exploring the use of novel therapies for OA such as aggrecanase and PACE4 inhibitors, as well the development of intra-articular delivery systems.
