Elevated N-glycosylation of immunoglobulin G variable regions in myasthenia gravis highlights a commonality across autoantibody-associated diseases

C. Mandel-Brehm, M. L. Fichtner, R. Jiang, V. J. Winton, S. E. Vazquez, M. C. Pham, K. B. Hoehn, N. L. Kelleher, R. J. Nowak, S. H. Kleinstein, M. R. Wilson, J. L. DeRisi, K. C. OConnor

This study identifies elevated N-glycosylation in IgG variable regions in myasthenia gravis patients and shows it is not required for autoantigen binding.

Self-antigen driven affinity maturation is required for pathogenic monovalent IgG4 autoantibody development

M. L. Fichtner, C. Vieni, R. Redler, L. Kolich, R. Jiang, K. Takata, P. Stathopoulos, P. Suarez, R. J. Nowak, S. J. Burden, D. Ekiert, K. C. O'Connor

The paper investigates how self-antigen-driven affinity maturation contributes to the development of pathogenic monovalent IgG4 autoantibodies in myasthenia gravis, showing that high-affinity Fab-arm exchanged antibodies require specific mutations for pathogenic capacity.

Single-cell repertoire tracing identifies rituximab refractory B cells during myasthenia gravis relapses

R. Jiang, M. L. Fichtner, K. B. Hoehn, P. Stathopoulos, R. J. Nowak, S. Kleinstein, K. C. OConnor

The paper identifies persistent autoantibody-producing B cell clones in rituximab-treated myasthenia gravis patients during relapses, showing incomplete B cell depletion.
