Relapsing arthritis induced by cell transfer from collagen-immunised mice.
Collagen-induced arthritis is a well-established model of chronic inflammatory arthritis. We here introduce a development of this model which combines the benefits of adoptive transfer and sequential relapse. DBA/1 x B10.Q F1 hybrid mice were immunised with bovine type II collagen, and those which developed a sufficiently high level of arthritis served as donors of spleen cells transferred into BALB/c SCID hosts. After boosting with 500 microg collagen, the development of host arthritis was monitored over a period of up to 256 days, during which up to three successive peaks were detected. In comparison with bovine collagen, mouse collagen used for boosting induced a lower initial peak but higher relapses. As expected, the transferred disease was more uniform than the freshly induced one. Previous information suggests that a shifting cytokine balance between protective and aggressive T cells may account for the relapse and remission. This study provides a model of relapsing polyarthritis, obtained with normal immunocytes boosted with a well-defined protein antigen in animals not themselves treated with adjuvant. As such it is relevant to the etiology of inflammatory arthritis in man, and, if further developed, could be of value for testing new therapeutic strategies.
