 AB    Some experimental arthritic diseases can be prevented by treatment with
       anti-CD4 MoAbs. Trials with ongoing disease have not been successful so
       far. The aim of this study was to ascertain whether W3/25 could reverse
       adjuvant arthritis (AA), when beginning treatment on day 14, i.e. when
       the disease was established. Moreover, one group of animals treated with
       the anti-CD4 MoAb received OX8 MoAb at the same time, thus depleting
       CD8+ cells from circulation. During treatment with W3/25, a strong
       amelioration of inflammatory signals were observed, as assessed by means
       of paw volume increase and arthritic score. However, when treatment
       stopped, a rebound to arthritis signals occurred. The parallel depletion
       of CD8+ cells did not modify these effects, thus the combined treatment
       W3/25 + OX8 gave the same amelioration as treatment with W3/25 alone.
       These findings indicate that CD4+ cells play an important role in
       perpetuating rat AA. Moreover, CD8+ cells do not seem to have a
       regulatory role int he CD4+ cells responsible for the inflammatory
       response.
