Abstract

Objective: To highlight the key translational advances and interdisciplinary discussions from the 2025 University of Debrecen Musculoskeletal Symposium (UD-MUSK), focusing on osteoarthritis (OA) and related musculoskeletal (MSK) diseases. Method: The UD-MUSK Symposium convened international and local experts for keynote presentations and scientific dialogue spanning OA and MSK disease mechanisms, translational therapies, and tissue regeneration. Core topics included extracellular matrix (ECM) remodelling, cell/gene therapies, animal disease models, chronic stress, autoimmunity, immunotherapies, and muscle and stem cell biology, reflecting the Symposium's broad interdisciplinary spectrum. Results: ECM proteomics revealed degradation fragments that act as drivers and potential modulators of OA, offering new biomarkers and therapeutic targets. Advances in cell- and gene-based therapies were presented, including the use of growth differentiation factor 6 (GDF6) and CRISPR approaches for cartilage and intervertebral disc repair. Large animal models simulating spatio-temporal changes in human OA, and studies demonstrating chronic stress-accelerated OA via neuroendocrine mechanisms, were highlighted. Novel strategies in immune modulation, such as chimeric antigen receptor (CAR) T cell therapy for autoimmune myopathies, alongside research on muscle regeneration and circadian regulation by mechanical loading, further exemplified the translational breadth of the meeting. Conclusion: The symposium underscored the value and need of integrating molecular research and disease modeling. Interdisciplinary collaboration continues to enhance understanding of MSK disease mechanisms and supports development of targeted, regenerative therapies with translational potential for OA and related disorders.
