IL6R and myasthenia gravis: In this study, we investigated the efficacy and potential mechanisms of action of IL-6 receptor (IL-6R) antibody treatment in an AChR-immunized experimental autoimmune myasthenia gravis (EAMG) mouse model, an animal model that exhibits immunopathological features closely mimicking human myasthenia gravis, including muscle weakness and AChR autoantibodies in serum (18).
