This is an important contribution, adding to the understanding of bone remodeling, which is not just relevant to arthritis but also to degenerative bone changes. Degenerative and inflammatory joint diseases lead to a destruction of the joint architecture. Whereas degenerative osteoarthritis results in the formation of new . Figure 3 New bone formation next to inflamed joints is increased upon blockade of DKK (a) Microphotographs of toluidine blue–stained joint sections of, ”from.

Development of criteria for the classification and reporting of osteoarthritis. The binding of integrins to ECM proteins activates diverse non-receptor protein tyrosine kinase signalling pathways, including the FAK, c-Src and Syk pathways.
Dickkopf-1 DKK-1 has been shown to be a major regulator of joint remodelling, which is associated with the bone erosion that occurs in different types of inflammatory arthritis such as RA [ 1011 ]. Deletion of a single allele of the Dkk1 gene leads to an increase in bone formation and bone mass. Circulating dickkopf-1 and radiological progression in patients with early rheumatoid arthritis treated with etanercept. Bone Tissue pediatric intracranial germ cell brain tumor.
Integrins are cell surface adhesion receptors that link the cell surface to the extracellular matrix ECM or to other cells.
