Further, the expression levels of 17 immune cells were statistically significant between the Sepsis and the Control groups (p < 0.05) (Fig 9B), respectively: B cells memory, B cells naive, Eosinophils, Macrophages M0, Macrophages M1, Macrophages M2, Mast cells activated, Mast cells resting, Monocytes, Neutrophils, NK cells resting, Plasma cells, T cells CD4 memory activated, T cells CD4 memory resting, T cells CD4 naive, T cells CD8, and T cells regulatory (Tregs). The gene discussed is CD8A; the disease is Sepsis.
