As shown in Figure 4, compared with sham group, CD3+, γ/δ, CD4+, and CD4+/CD8+ T lymphocytes were significantly decreased from (80.75 ± 10.24)%, (18.64 ± 7.73)%, (24.59 ± 6.60)%, and (1.89 ± 0.52) to (38.38 ± 10.90)%, (7.62 ± 1.79)%, (7.95 ± 2.95)%, and (0.97 ± 0.67) in the sepsis group. This evidence concerns the gene CD4 and Sepsis.
