This paper investigates the heterogeneity of autoantibodies in patients with myasthenia gravis (MG), focusing on their diverse pathogenic properties and temporal fluctuations. The researchers utilized advanced cell-based assays to analyze serum samples, revealing that different immunoglobulin isotypes (IgG, IgM, IgA) and IgG subclasses contribute to the disease through varying mechanisms like complement activation, receptor internalization, and acetylcholine binding site blocking. The findings suggest that a comprehensive understanding of each patient's unique autoantibody profile could lead to more personalized and effective therapeutic strategies for MG.
