摘要

Little is known about pathogenesis -- and especially about involvement of CD8(+) T-cells -- in late-onset myasthenia gravis (LOMG). Remarkably, outstanding CD8(+) TCRVbeta-subset expansions were found in 64% and 72% of recent onset LOMG or thymoma-associated MG (vs. 16% with early-onset MG (p<0.0002); 21% in older controls (p<0.001)). In LOMG, ~25% of the expanded cells initially showed a naive CD62L(+hi)/CD45RA(+) recent thymic emigrant (RTE)-like phenotype. These expansions associated significantly with IgG antibodies against cytomegalovirus (p<0.036), IL-12 and/ or IFN-alpha2 (p<0.03). The CD8(+) TCRVbeta expansions were stable over 5years, but RTE markers declined.
