Angiogenesis and arthritis.
Indices of angiogenesis are increased in synovia from patients with arthritis, and vascular proliferation may contribute to the pathogenesis of synovitis, pannus growth, bone and cartilage destruction, and osteophyte formation. Pharmacological inhibition of angiogenesis therefore has potential as a therapeutic strategy in human arthritis. However, vascular growth is also essential for normal development, female reproduction and tissue repair. Selective inhibition of undesirable angiogenesis requires an understanding of the different regulatory mechanisms in pathological and physiological angiogenesis. This review outlines the evidence that the rate of angiogenesis is increased in the inflamed human synovium, and possible approaches to, and consequences of, the modulation of vascular growth.
