Figure 1 Immunophenotypic analysis of Tc1, Tc2, Th1, and Th2 cells. The lymphocytic population was initially defined using a forward (FSC) and side scatter (SSC) gate (A). CD4+ T cells and CD8+ T cells were then gated based on the CD8 antigen (B). Representative fluorescence-activated cell sorting analysis of CD8−IFN-γ+ Th1 cells and CD8+IFN-γ+ Tc1 cells from a PGF patient (C), a GGF patient (D), an HD, and (E) CD8−IL-4+ Th2 cells and CD8+L-4+ Tc2 cells from a PGF patient (F), a GGF patient (G), and an HD (H) are provided.

Figure 2 IFN-γ (A) and IL-4 (B) levels in BM plasma, as measured by cytometric beads assay. The PGF patients exhibited significantly elevated plasma IFN-γ levels compared with HD and decreased plasma IL-4 levels compared with GGF patients and HD.

Figure 3 The percentages of Th1 (A) and Th2 (B) cells among CD4+ T cells and Tc1 (D) and Tc2 (E) cells among CD8+ T cells. Th1/Th2 (C) and Tc1/Tc2 (F) ratios are indicated. Statistical analyses were performed using the Mann-Whitney U test.
