Starting with T cell stimulating receptors, percentages of CD27 expression were highest on blood-circulating CD4+ T cells (87.52 ± 2.57% of CD4+ T cells) and CD8+ T cells (60.59 ± 4.98% of CD8+ T cells) followed by ascites samples and tumor tissues having least CD27+ T cell proportions (Figures 5A, 6A). This evidence concerns the gene CD4 and neoplasm.
