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...
متن کاملDeficiencies in anti-acetylcholine receptor antibody measurement in myasthenia gravis.
In a retrospective case note study of 86 patients with myasthenia gravis, 60 had an anti-acetylcholine receptor antibody assay performed by the regional immunology laboratory. Antibody was detected in 38% which compares with 66-93% in other series. Whilst the use of staphylococcal protein A to precipitate the antibody-receptor complex, rather than anti-human immunoglobulin, may be partly respon...
متن کاملExperimental 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...
متن کاملAnalysis of peripheral B cells and autoantibodies against the anti-nicotinic acetylcholine receptor derived from patients with myasthenia gravis using single-cell manipulation tools
The majority of patients with myasthenia gravis (MG), an organ-specific autoimmune disease, harbor autoantibodies that attack the nicotinic acetylcholine receptor (nAChR-Abs) at the neuromuscular junction of skeletal muscles, resulting in muscle weakness. Single cell manipulation technologies coupled with genetic engineering are very powerful tools to examine T cell and B cell repertoires and t...
متن کاملPathological mechanisms in experimental autoimmune myasthenia gravis. II. Passive transfer of experimental autoimmune myasthenia gravis in rats with anti-acetylcholine recepotr antibodies
Passive transfer of experimental autoimmune myasthenia gravis (EAMG) was achieved using the gamma globulin fraction and purified IgG from sera of rats immunized with Electrophus electricus (eel) acetylcholine receptor (AChR). This demonstrates the critical role of anti-AChR antibodies in impairing neuromuscular transmission in EAMG. Passive transfer of anti-AChR antibodies from rats with chroni...
