As shown in Figure 11, OSBPL members exhibited the strongest positive correlations with the levels of CD4+ T cells, M1 macrophages, neutrophils, monocytes, and cancer-associated fibroblasts, while showing negative correlations with CD4+ T cells, type 2 helper T (Th2) cells, and monocytes by QuanTIseq. The gene discussed is CD4; the disease is cancer.
