Induction of adjuvant arthritis in the rat by various bacterial cell walls and their water-soluble components. 1976

T Koga, and S Kotani, and T Narita, and C M Pearson

A number of purified cell walls of various gram-positive bacteria had arthritogenic activity in the rat. The water-soluble adjuvant-active component(s), which were isolated from some of these cell walls by utilizing a peptidoglycan-degrading enzyme, did produce severe adjuvant arthritis. However, the components obtained by digestion with glycan-degrading enzymes failed to produce arthritis. Thus, the present finding indicates the importance of a peptidoglycan portion, especially its intact glycan chain, for induction of adjuvant arthritis.
