Unravelling the pathogenesis of myasthenia gravis

Myasthenia gravis is a relatively rare neurological disease that is associated with loss of the acetylcholine receptors that initiate muscle contraction. This results in muscle weakness, which can be life-threatening. The story of how both the physiological basis of the disease and the role of acetylcholine-receptor-specific antibodies were determined is a classic example of the application of basic science to clinical medicine, and it has provided a model for defining other antibody-mediated disorders of the peripheral and central nervous systems.
