1. Extracellular Matrix Remodelling-Proteoglycan and collagen turnover in arthritis
Sammanfattning : Rheumatoid arthritis is a chronic, inflammatory and systemic disease characterised by joint destruction and pannus formation. To enlarge the understanding how pannus and granulation tissue are formed two animal models were used; one using cartilage wrapped in cotton and implanted into a rat air pouch (AP) and one where mBSA induced arthritis (AIA) was performed.

2. Chondrocyte-matrix interactions: with emphasis on the collagen binding integrin a10ß1
Sammanfattning : The work in this thesis has been focused on chondrocyte integrins and their interaction with the matrix proteins chondroadherin (CHAD) and collagen type II (CII). Affinity purification of CHAD-binding proteins from chondrocyte lysate, followed by immunoprecipitation of EDTA-eluted material identified alpha2beta1 as a CHAD-binding integrin. LÄS MER
3. The collagen fibrillar network: Sequential degradation of its constituents by tissue metalloproteinases
Sammanfattning : The cartilage matrix is made up of a fibrillar meshwork comprising type II collagen and other associated proteins. One main function of this network is to retain the large aggregating proteoglycan, aggrecan, a vital component in the regulation of fluid flux in cartilage. LÄS MER
4. T cells in Autoimmunity: studies on murine type II collagen-induced arthritis
Sammanfattning : Collagen-induced arthritis (CIA) is a mouse model for rheumatoid arthritis, in which autoimmunity is induced by immunization with type II collagen (CII), a cartilage-specific protein. In the present work, alpha/beta T cells were shown to be required for CIA and for the production of anti-CII IgG antibodies, whereas gamma/delta T cells were neither necessary nor sufficient for development of CIA.

5. Studies on chondroadherin-an extracellular matrix leucine-rich repeat protein
Sammanfattning : This thesis describes chondroadherin, one of the leucine-rich repeat proteins in the extracellular matrix (ECM) of cartilage. Chondroadherin defines a subgroup of its own by not having an N-terminal extension, having a different cysteine pattern and by being devoid of carbohydrate substitutions. LÄS MER
