Type II collagen without adjuvant induces eosinophilic arthritis.

Research output: Contribution to journalArticle


Eosinophilia is a characteristic feature of many inflammatory diseases including inflammatory bowel disease and asthma. It also occurs in a subtype of rheumatoid arthritis but the role of eosinophils has been unclear and animal models have been lacking. Here, we introduce a new mouse model to study the role of eosinophilia in arthritis. Intraperitoneal injection of type II collagen alone, without any adjuvant, was sufficient to induce chronic arthritis in a mouse with transgenic T cells specific for type II collagen. The arthritis was accompanied by infiltration of eosinophils into the synovial tissue and the disease could be blocked with neutralizing anti-IL-5 antibodies. To our knowledge, this is the first description of an eosinophilic disease form of destructive arthritis.
