| Description | Journal: Scandinavian Journal of Rheumatology Over 20 successive intra-articular injections of autologous or homologous cathepsin D-Fab2 produce chronic destructive arthritis marked by dense round-cell infiltration, epithelioid hyperplasia of the lining layer, lymph nodules and a few germinal centres. 75% of the animals become Rf-positive and develop high titers of homoreactants to cathepsin D-Fab2. Both these antibodies are synthesized in the synovial membrane and pha-gocytosed. Careful study of control animals makes it possible to exclude the possibility that the effects observed are due to the repeated joint traumata, to endo or exotoxin like substances, to chromatographed lysosomal material or to traces of cathepsin D. Autologous and homologous Fab, have largely identical effects, while those of homologous or autologous IgG are much less marked. These comparisons suggest that the cathepsin D site of IgG acts as a strong antigen when exposed in the joint. The synovitis thereby induced has a pronounced tendency to spread to the left knee joint which was injected with physiological saline. |
