Compared with CD4−CD8+ T cells, a higher frequency of CD4dimCD8+ T cells express IFNγ. (A-B) Representative FACS plots and cumulative data showing the percentage of IFNγ-expressing CD4dimCD8+ T cells and CD4−CD8+ T cells. Unstimulated peripheral blood mononuclear cells of 3 MAS patients and mononuclear cells of 3 pHLH patients were analyzed by flow cytometry. Statistical significance was calculated by using Wilcoxon's matched pairs signed rank test. *P < .05.
