In vitro and in vivo actions of acetylcholine receptor educated suppressor T cell lines in murine experimental autoimmune myasthenia gravis.

Immunization of C57Bl/6 mice with Torpedo acetylcholine receptor (AChR) leads to EAMG, experimental autoimmune myasthenia gravis, with characteristic clinical, electrophysiological, and immune features. Present in the lymphoid organs of mice with EAMG are AChR specific suppressor T cells: these cells can be grown in vitro as T cell lines. These lines are able to suppress the in vitro response to AChR, and can suppress the in vivo development of EAMG.
