IgG1 −/− mice showed significantly higher levels of IFN-γ and IL-6 production upon AChR stimulation as compared to wild type mice, whereas IL-4 levels were comparable in both groups. Idiopathic inflammatory myopathies (IMs) are a heterogeneous group of muscle disorders. Two cases of familial myasthenia gravis are reported.
