CHAPTER 6 CHAPTER 6: PAPER III PAPER III ___________________________________________________________________________ Introductory remarks This manuscript focuses on the pathogenesis <strong>of</strong> cartilage, and evaluates the different proteolytic degradation processes for aggrecan, which vary <strong>between</strong> the OA-stages. It is <strong>important</strong> to understand the different degrading processes <strong>of</strong> aggrecan if we want to target the right proteases at a certain stage <strong>of</strong> disease. 77
