TACE inhibition: a new approach to treating inflammation

Clinical trials showing the benefits of reducing the effects of TNF-alpha in rheumatoid arthritis have highlighted the key role of the cytokine TNF-alpha in this inflammatory condition. A new approach to reducing the effects of TNF-alpha is to decrease its synthesis by inhibiting TNF-alpha converting enzyme with GW3333. In rat models of arthritis, GW3333 has some beneficial effects. Further longer-term studies of GW3333 in animal models are required to determine whether its benefit is maintained. TACE inhibition may represent a new approach to treating inflammation.
