As showed in Figure 4A, the percentages of NK cells (F test p = 0.000), NKT cells (F test p = 0.000), CD3+ T cells (F test p = 0.004), and CD8+ T cells (F test p = 0.006) in the lymphocytes declined with the health status changing from healthy, inflammation to tumor. The gene discussed is CD8A; the disease is neoplasm.
