This report describes the in vivo and in vitro induction of murine (AChR)-specific suppressor T cells (Ts) and T cell factors (TsF), and the development of an appropriate assay system for their measurement. The assay described is based on the in vitro Mishell-Dutton culture system. Using this assay, it was shown that the AChR-specific helper cell is an Lyt-2- radiosensitive T cell. Moreover, the proliferating cell measured in the lymphocyte transformation assay was shown to provide AChR-specific T cell help. In vivo induction of Ts cells is achieved by injection of soluble AChR; potent AChR-specific suppression is found in the spleen 1 wk later. In vitro induction of Ts cells involves the primary education of naive splenocytes by culturing them with high concentrations of AChR. Both the in vivo- and in vitro-induced Ts cells were shown to secrete AChR-specific factors that mediate their suppressive effects. The possibility of specifically suppressing the AChR-immune response may be of a particular clinical importance since the AChR is the target autoantigen in the neuromuscular autoimmune disease myasthenia gravis.

A type II collagen-specific arthritogenic lymphokine has been identified in the rat. Arthritogenic factor (AF) is a 65 kD protein generated in vitro by T cells from rats with collagen arthritis, and it induces an erosive, proliferative synovitis when injected into the knee joint of syngeneic naive recipients. Complement does not appear to be required. These data identify a potential T cell-mediated effector mechanism in this model, and suggest that AF may function in other inflammatory synovial diseases.
