OBJECTIVE: To investigate the capacity of taxol, a microtubule stabilizer, to inhibit collagen-induced arthritis (CIA), a model of rheumatoid arthritis. METHODS: Louvain rats were immunized with type II collagen (day 0) to induce arthritis. Taxol was administered beginning on day 2 (prevention protocol) or at arthritis onset on day 9 (in either a high-dose or low-dose suppression protocol). Rats were assessed clinically and radiographically for arthritis severity. Cellular and humoral immune responses to type II collagen were also evaluated. RESULTS: Institution of taxol prior to arthritis onset completely precluded the development of CIA (P < 0.0001 versus controls). It also suppressed established clinical disease (high-dose protocol P < 0.0000001; low-dose protocol P < 0.0001) and radiographic erosions (high-dose protocol P < 0.00001; low-dose protocol P < 0.001) compared with controls. Levels of IgG antibodies, but not delayed-type hypersensitivity, to type II collagen were reduced after taxol administration. CONCLUSION: Taxol completely prevented the induction of CIA and caused significant regression of existing arthritis.
