The IFN-γ producing ability of CD4⁺ T cells, CD8⁺ T cells, and NK cells. PMA/ionomycin-stimulated lymphocyte function assay was performed in patients with DLBCL and HCs. A Representative FACS dot plots showing the production of IFN-γ in CD4⁺ T cells, CD8⁺ T cells and NK cells. B The percentages of IFN-γ⁺ cells in CD4⁺ T, CD8⁺ T cells and NK cells from patients with lymphoma and HCs are shown in bar graphs (mean ± SD). C The percentages of IFN-γ⁺ cells in CD4⁺ T, CD8⁺ T cells and NK cells from patients with low- to low-mediate-risk (IPI scores 0–2) and mediate-high- to high-risk (IPI scores 3–5) are shown in bar graphs (mean ± SD)
