IgA autoantibodies demonstrate a novel mechanism of MuSK myasthenia gravis pathology
Masi G, Chen K, Bayer A, Bayarri-Olmos R, Pham M, Wallace A, Falso S, Evoli A, Iorio R, Hoehn K, Iwasaki A, Nowak R, O’Connor K. IgA autoantibodies demonstrate a novel mechanism of MuSK myasthenia gravis pathology. Brain 2025, 149: awaf410. PMID: 41147199, PMCID: PMC13005154, DOI: 10.1093/brain/awaf410.Peer-Reviewed Original ResearchThis study investigates the role of IgA antibodies in MuSK myasthenia gravis, showing they coexist with IgG4 antibodies, exhibit unique pathogenic potential, and can resist B-cell depletion therapy.Therapeutic IgG- and IgM-specific proteases disarm the acetylcholine receptor autoantibodies that drive myasthenia gravis pathology
