Figure S5. CD4+ T cell percentage positivity. Comparison of the expression levels as determined by percentage positivity of PD-1, PD-L1 and PD-L2 on CD4+ T cell subsets (CD27+ and CD27-) between patients with sepsis and healthy controls. (DOCX 465 kb

Figure S1. Example of gating used in data analysis. The isotype (and FMO) was used to set the negative gate, and then the percentage of positive cells was taken as the percentage above this gate. Separate healthy and sepsis isotypes were used (Figure S1a and b respectively). Figure S1c shows an example of MFI signalling in healthy and sepsis isotypes, and healthy, sepsis survivor and sepsis non-survivor samples. (DOCX 441 kb
