Representative results of FACS analysis of MG(+) and MG(−) thymomas.

FACS analysis of naive CD4⁺ and CD8⁺ subsets in a nonneoplastic thymus control (patient 24), a WHO type B2 thymoma with MG (patient 3), and a WHO type AB thymoma without MG (patient 10). Both subsets are highly reduced in the MG(−) thymoma compared with the control thymus and the MG(+) thymoma.
