In addition, we observed that CGB5 was associated with various immune cells in gastric cancer, presenting positive trends for macrophage M0, activated mast cells and resting memory CD4 T cells (Figures 12B–D), negative trends for activated memory CD4 T cell and CD8 T cells (Figures 12B–D), and a trend of negative correlation with the activated memory CD4 T cells and CD8 T cells (Figures 12D, F). This evidence concerns the gene CD4 and gastric cancer.
