In addition, through examining the differences between eosinophil, neutrophil, CD4+ memory resting T cells, and CD8+ T cells in the blood of patients in the HCC and control groups by flow cytometry (Figure 8(d)), the difference in the levels of CD4 + memory T cells and CD8+ T cells between the HCC and normal groups were confirmed. Here, CD8A is linked to hepatocellular carcinoma.
