Research

My research is concentrated on the pathology of the musculoskeletal system with emphasis on two important and common diseases seen in our domestic animals; Osteoarthritis (OA) and Osteoschondoris (OC)

The aim of the research

To find, create and use biomarkers for inflammatory, anabolic, catabolic, and painful processes in connection with OA and OC, in order to detect the tissue changes early and hence be able to prevent development of chronic irreversible damage to the joints. The studies aim to delineate the early development with progression towards chronic tissue destruction, in order to understand the pathogenesis. This knowledge is crucial when trying to prevent chronic damage in OA and OC joints.

On-going research projects

Identification of unique protein fragments found in inflamed articular cartilage in vitro. In addition, evaluate if these molecules are present in serum and synovial fluids from animals with early subclinical joint lesions of OA and OC diseases. The aim of the research is to design a biomarker panel for clinical use, detecting early reversible joint lesions. The research is also translational aiming to detect early joint lesions in man. The project is a collaboration between SLU (Professor Eva Skiöldebrand) and Sahlgrenska Akademin, Gothenburg (Professor Anders Lindahl), USA (Professor Cathy Carlson, StPaul-Minneapolis, Minnesota) and Nya Zeeland (Keren Dittmer, DVM, PhD, Massey University).

The research has been funded by FORMAS, SHF and Vetenskapsrådet.
