T cell lines responding to Mycoplasma arthritidis and chondrocytes in the Mycoplasma arthritidis infection of rats.
CD 4+ T cell lines responding specifically to Mycoplasma (M.) arthritidis were established from spleen and lymph nodes of a Lewis rat infected with M. arthritidis. The T cell response to M. arthritidis was MHC class II-restricted. M. arthritidis-reactive T cell lines also responded to syngeneic chondrocytes suggesting that M. arthritidis and chondrocytes may share a common antigenic structure. The T cell lines reacting with chondrocytes may play an important role in the chronic stage of the M. arthritidis-induced arthritis of rats by maintaining immune reactions initiated by M. arthritidis antigens and originally established to eliminate the mycoplasmas. These autoimmune reactions could perpetuate after disappearance of the mycoplasmas and possibly last for the entire lifetime.
