Percentage of mature naive CD4⁺⁺ T cells is highly reduced in MG(−) thymomas.

FACS analysis of naive thymocyte subsets shows a highly significant reduction of mature naive CD4⁺ T cells in MG(−) thymomas compared with MG(+) thymoma patients and nonneoplastic thymus controls and a significantly increased percentage of mature naive CD8⁺ T cells in MG(+) thymomas. *Statistically significant alteration in comparison with MG(+) thymomas and thymus controls. #Statistically significant alteration compared with thymus controls.
