Abstract excerpt
We report a case of myasthenia gravis associated with marked expansion of an unusual CD16(+)CD56(-)2B4(+) NK subset. These atypical cells were characterized by poor cytotoxicity against CD48(+) target cells and high proliferation due to 2B4/CD48 interaction. IL18, IFN-gamma and TGF-beta levels were profoundly different in this patient than in healthy donors. Immunosuppressive treatment induced disease remission...
