The percentages of IFN-γ⁺CD4⁺T cells and IL-2⁺CD4⁺T cells could differentiate rejection from non-rejection upon activation. Comparison of the production of IFN-γ, IL-2 and IL-17 in resting CD4⁺T cells (a–c) and in CD4⁺T cells stimulated with cell stimulation cocktail (d–f) between liver transplant recipients with and without acute rejection. Bars represent mean and standard deviation
