CD4 and neoplasm: With respect to the HBV−HCC group (GSE14520, n = 204), the signatures of resting memory CD4+ T cells (q-value < 0.001), activated memory CD4+ T cells (q-value < 0.001), activated natural killer cells (q-value < 0.001), resting dendritic cells (q-value < 0.001), and resting mast cells (q-value < 0.001) were found to predominate in tumor tissue.
