[Induction of flare-ups of chronic progressive polyarthritis in mice after injection of type II homologous collagen].
Immunization by heterologous type II collagen induces in mice a sudden onset of subacute polyarthritis. In order to form a model of auto-immune pathology, we immunized DBA/1 mice with homologous type II collagen extracted from mice xiphoid process; the induced disease corresponds to a progressive chronic polyarthritis with bouts interspersed with remissions, and predominates especially in males. Type II anti-collagen auto-antibodies are found in the serum, with no correlation between the level of mice type II anti-collagen immunoglobulins G and the clinical manifestations of the disease. The histological study demonstrates signs of hyperplastic villous synovitis, with a discrete and infrequent infiltration with mononuclear cells. The model that is obtained is similar to rheumatoid polyarthritis, but also to spondylo-arthropathies.
