Analysis with the CIBERSOFT software showed that HCST expression was correlated with tumor-filtrating immune cells, including naïve B cells, activated DCs, eosinophils, M2 macrophages, resting mast cells, monocytes, neutrophils, resting NK cells, plasma cells, activated CD4 memory T cells, resting CD4 memory T cells, CD8 T cells, follicular helper T cells, gamma delta T cells, and regulatory T cells (all, p < 0.001) (Figure 9). This evidence concerns the gene CD4 and neoplasm.
