Abstract:
The purpose of this review is to summarize the role that murine models of arthritis are playing in the understanding of human rheumatoid arthritis and how leukotriene B(4) (LTB(4)) is emerging as an important target in this field. Both the collagen-induced arthritis (CIA) model and the K/BxN serum transfer arthritis model have contributed to outline the potential mechanisms involved in inflammatory arthritis. Indeed, the CIA model has contributed to the development of effective anti-TNFalpha and anti-IL-1beta based treatments for RA that are currently in the clinic. Many recent studies in mouse models have suggested a critical role for LTB(4) and its receptors in the development of inflammatory arthritis. Inhibitors of LTB(4) biosynthesis as well as LTB(4) receptors are protective in mouse models of RA and mice deficient in the LTB(4) biosynthetic enzymes or LTB(4) receptors are resistant to disease development suggesting several promising targets for RA in this pathway.
