The percentages of IFN-γ⁺CD4⁺T cells correlate with liver function upon activation. Correlations of AST and ALT, and the percentages of IFN-γ⁺CD4⁺T cells in liver transplant recipients with (a, b) and without (e, f) acute rejection, respectively. Correlations of AST and ALT, and the percentages of IL-2⁺CD4⁺T cells in liver transplant recipients with (c, d) and without (g, h) acute rejection, respectively. Bars represent mean and standard deviation. AST aspartate transaminase, ALT alanine amiotransferase
