Spontaneous production of anti-IFN-alpha and anti-IL-12 autoantibodies by thymoma cells from myasthenia gravis patients suggests autoimmunization in the tumor.

Myasthenia gravis (MG) is mediated by autoantibodies to the acetylcholine receptor (AChR), expressed in muscle and rare thymic myoid cells. Most early-onset cases show thymic lymph node-type infiltrates, including pre-activated plasma cells spontaneously producing anti-AChR antibodies. Since these are not evident in the associated thymomas found in another 10% of MG patients, AChR-specific B ce...

Anti-agrin autoantibodies in myasthenia gravis.

OBJECTIVE Because the extracellular matrix protein agrin is essential for neuromuscular junction formation and maintenance, we tested the hypothesis that autoantibodies against agrin are present in sera from patients with myasthenia gravis (MG). METHODS We determined the presence of anti-agrin antibodies in 54 sera from patients with generalized MG using a solid-phase ELISA with purified mini...

Autoantibodies in thymoma-associated myasthenia gravis with myositis or neuromyotonia.

BACKGROUND About 50% of patients with thymoma have paraneoplastic myasthenia gravis (MG). Myositis and myocarditis or neuromyotonia (NMT) will also develop in some. Patients with thymoma-associated MG produce autoantibodies to a variety of neuromuscular antigens, particularly acetylcholine receptor (AChR), titin, skeletal muscle calcium release channel (ryanodine receptor [RyR]), and voltage-ga...

Myasthenia gravis patients with anti-MuSK antibodies.

In myasthenia gravis (MG) patients without detectable anti-acetylcholine receptor (anti-AChR) antibody, referred to as seronegative myasthenia gravis patients, there is a variable proportion of patients with antibodies against the muscle-specific kinase (MuSK). MuSK antibodies were found in 8 (29.6%) of our 27 patients with generalized MG without anti-AChR antibodies. All these patients were fe...

Thymoma complicating myasthenia gravis

Purpose: We conducted this study to retrospectively analyze the clinical effects of surgical resection for patients with myasthenia gravis (MG) complicated with thymoma. Methods: 162 patients with myasthenia gravis complicated with thymoma, that were admitted to our hospital and underwent surgical disease resection from Nov. 1993 to Nov. 2015, were selected for this study. Analyzed were the pat...
