An investigation of experimental myasthenia gravis.

Guinea-pigs were immunized with antigen prepared from calf thymus and muscle, and from guinea-pig thymus, and rats were immunized with antigen prepared from rat thymus and rat muscle. There was an increased incidence of delayed hypersensitivity and circulating thymus antibodies in the immunized guinea-pigs and an increased incidence of thymitis in the immunized guinea-pigs and rats. However, wh...

Experimental autoimmune myasthenia gravis.

Injection of animals with purified acetylcholine receptor in complete Freund's adjuvant causes development of antibodies which crossreact with receptors in muscle. The crossreacting antibodies impair neuromuscular transmission. Animals with experimental autoimmune myasthenia gravis (EAMG) are excellent models for studying the complex mechanisms by which the autoimmune response to receptor in my...

Experimental myasthenia gravis. A murine system

Mice from eight inbred strains were immunized with acetylcholine receptor (AChR) purified from Torpedo californica. All mice developed high concentrations of serum antibodies (10(-6) M) against the immunogen and approximately 80% possessed antibodies reactive with mouse nicotinic AChR. 33% of the mice immunized (n = 236) developed muscular weakness and flaccid paralysis. Behavioral, electrophys...

Erythropoietin Ameliorates Experimental Autoimmune Myasthenia Gravis

Myasthenia gravis (MG) is an autoimmune disorder characterized by weakness and fatigability of skeletal muscles. Erythropoietin (EPO) is a cytokine required to maintain erythroid cells. Recombinant human EPO (rHuEPO) was found to act also on immune cells. Beneficial effects of rHuEPO therapy have been demonstrated in several experimental autoimmune models. We have tested the effect of rHuEPO on...
