  "textContent": "Myasthenia gravis (MG) is a rare autoimmune disease in which the immune system attacks the connection between nerves and muscles. This attack causes muscle weakness that can affect vision, movement, speech, swallowing, and breathing. While many patients respond to treatment, others develop a severe, treatment-resistant form of the condition known as refractory MG. Currently, there are no reliable biomarkers to help doctors predict which patients will respond to therapy and which will not.",
