[Laminin-dependent inflammatory response in synovial fibroblasts of rheumatoid arthritis patients]
Abstract
Elevated expression of matrix-metalloproteinases (MMP) contributes to cartilage destruction in rheumatoid arthritis. We report on a novel pathway of inflammatory activation of synovial fibroblasts that is induced by TGF-beta and laminin (extracellular matrix) and leads to increased expression of the proteases MMP-3 and MMP-10. Neither costimulation by the central inflammatory cytokines TNF-alpha and IL-1beta nor NFkB signalling is needed for this pathway.
