Programmed death protein 1/programmed death ligand 1 (PD-1/PD-L1) expression on CD4+ T cells. a-c Comparison of the mean fluorescence intensity (MFI) of PD-1, PD-L1 and PD-L2 on T cells in patients with sepsis compared with healthy controls. d-f Comparison of the MFI of PD-1, PD-L1 and PD-L2 between CD27+ T cells and CD27- T cells within patients with sepsis. The boxes below show the corresponding proportion of positive cells for each comparison, with corresponding p values. *Significant p values
