CBX4 showed significant negative correlations with infiltrating B cells (p < 0.05) and CD4+ T cells (p < 0.01), and positive correlations with myeloid derived suppressor cells (MDSCs) (p < 0.05) and cancer associated fibroblast (CAFs) (p < 0.001), as well as a low immunoscore. The gene discussed is CD4; the disease is cancer.
