Biography

Dr Oksana Kehoe is a Senior Lecturer in Inflammation Biology at the School of Medicine and Lead of Rheumatology Research laboratory in the Robert Jones & Agnes Hunt Orthopaedic Hospital at Oswestry.

Dr Kehoe completed her PhD in the RE Kavetsky Institute of Experimental Pathology, Oncology and Radiobiology of National Academy of Sciences of Ukraine, Kyiv where she was awarded a Fellowship of Ukrainian Government for young scientist.

Her academic career started in Ukraine, where she worked as a Research Scientist in the Department of Biochemistry, Taras Shevchenko National University of Kyiv, Ukraine. After moving to the UK in 2000, Dr Kehoe worked as a Postdoctoral Research Associate at Cardiff University (2000-2002) and the University of Manchester (2002-2005). She joined Keele University and Institute for Science & Technology in Medicine at the RJAH Orthopaedic Hospital as a Research Fellow in 2006.

Research and scholarship

Research theme: Regenerative Medicine

The research within our laboratory is focused on understanding mechanisms of rheumatoid arthritis progression and possible treatments including mesenchymal stem cells (MSCs), mesenchymal stem cell conditioned medium and mesenchymal stem cell-derived extracellular vesicles. We also try to find out how stem cells can be “encouraged” to perform better in aging and in disease such as arthritis. In our research we use many approaches, from cell biology, to biochemistry, molecular biology and animal models.

Current active projects
  1. Mesenchymal stem cell-derived extracellular vesicles as therapeutic agents in arthritis
    MSCs function predominantly through paracrine mechanisms, via growth factors, cytokines, chemokines and bioactive, membrane-bound extracellular vesicles (EVs) found in mesenchymal stem cell conditioned medium. We are pursuing simultaneous characterisation of EVs derived from human MSCs cultured in different conditions to determine the impact of culture conditions upon the molecular composition of EVs. We are using pre-clinical and clinical samples to test the anti-inflammatory and immunomodulatory properties of EVs.
  2. The in vitro effect of syndecan-3 gene knockout on bone marrow derived mesenchymal stem cells’ properties
    Inflammation is a central feature of rheumatoid arthritis that affects around 1% of the population and can result in disability and morbidity. The immunomodulatory effects of bone marrow derived mesenchymal stem cells has been widely studied and the recent observations that syndecan-3 (SDC3) is selectively pro-inflammatory in the joint led us to hypothesise that SDC3 might play an important role in MSCs biology. Syndecans are heparan sulphate proteoglycans expressed by endothelial cells of blood vessels and play a role in trafficking of inflammatory cells in an arthritis model.
  3. Achieving the large-scale expansion of allogeneic umbilical cord mesenchymal stromal cell
  4. PARIS: Psoriatic Arthritis – Resistance to TNF Inhibitors Study
    Psoriatic arthritis (PsA) is a chronic inflammatory immune-mediated disease. It affects up to 40% of people with psoriasis and it is associated with several comorbidities such as obesity, diabetes, metabolic syndrome and hypertension. It is difficult to diagnose because of its diverse symptoms manifesting of axial and peripheral arthritis, enthesitis, dactylitis, skin changes and nail dystrophy. Currently, different treatments exist to treat inflammation and pain. When patients do not respond to standard first line treatment, they are treated with biologic drugs such as Tumor Necrosis Factor inhibitors (TNFi) in first instance. But these treatments are expensive and lack efficacy in 50% of the cases. It is important to find biomarkers that will predict the response of patients to TNFi, in order to treat them with the most appropriate biologic drug. In collaboration with Dr Jan Herman Kuiper, School of Pharmacy and Bioengineering, Keele and clinical Rheumatologists from the RJAH Orthopaedic Hospital, this project aims to analyze the concentration of potential biomarkers in blood of PsA patients to predict resistance to TNFi and help clinicians to prescribe the most appropriate treatment in the first instance.
