Immuno-based Profiling of knEe OA Patients to Predict reSponse to Regenerative Treatment
Osteoarthritis (OA) is a highly prevalent degenerative musculoskeletal disease and a major cause of chronic disability worldwide. Its multifactorial origin contributes to determine the heterogeneous phenotypes and one unmet need is the lack of biomarkers to predict the individual response. Platelet-rich-plasma (PRP) injection is a minimally invasive autologous blood-derived approach for which we plan to define specific knee profiles predictive of response. We will take advantage of a unique multidisciplinary approach aimed at analysing clinics, imaging, and biomarkers of associated with clinical response. We will focus on inflammatory (Wnt system, IL1 pathway, PTX3) and antioxidant (primarily, DPP3/Keap1/Nrf2) pathways. We foresee that our results will allow a better allocation of immunomodulatory and regenerative therapies for a personalized approach in knee OA thus maximising the effectiveness of the healthcare allocation.
