TI Administration of a nondepleting anti-CD4 monoclonal antibody (W3/25)
prevents adjuvant arthritis, even upon rechallenge: parallel
administration of a depleting anti-CD8 monoclonal antibody (OX8) does
not modify the effect of W3/25.

AB The aim of this study was to determine the effects of the anti-CD4
monoclonal antibody (mAb) W3/25, found to be nondepleting, on the onset
of rat adjuvant arthritis (AA), and, in addition, to ascertain whether
depletion of CD8+ cells during the same period could interfere with
those effects. Female Wistar rats in which AA had been induced were
treated with W3/25 and/or OX8 (anti-rat CD8) mAb during the latency
period of arthritis. W3/25 alone or in combination with OX8 prevented
the inflammatory process of AA. When the protected groups were
rechallenged with a second dose of Mycobacterium butyricum no arthritis
was observed. Protected and nonprotected arthritic animals developed the
same anti-mycobacteria antibody levels as the arthritic control group.
This study indicates that a nondepleting anti-CD4 mAb can prevent AA,
while CD8+ lymphocytes do not appear relevant for the development of AA
and do not seem to have a regulatory role for CD4+ cells.
