Outline of Final Research Achievements |
Cas-L is a cytoplasmic docking protein essential for cellular migration and beta 1 integrin-mediated costimulation of T cells. Our current study expanded these findings on the role of Cas-L in the development of rheumatoid arthritis (RA) by analyzing the pathophysiological changes in a Cas-L -/- mouse collagen-induced arthritis (CIA) model, strongly suggesting that Cas-L plays a pivotal role in the pathophysiology of CIA, and that Cas-L may be a potential molecular target for the treatment of RA. Macrolide antibiotics have immunomodulatory properties that are distinct from their anti-bacterial functions. We synthesized 5-I, which is a new derivative of roxithromycin with less antimicrobial activity, and evaluated its immunomodulatory effects. Administration of 5-I to mice with CIA reduced the severity of arthritis, and this effect was also observed when treatment was delayed till after the onset of disease, suggesting that 5-I may be useful as a potential therapeutic agent for RA.
