The expression of COL1A1 was significantly correlated with the expression of marker genes from tumor-infiltrating CD8+ T cell (CD8B), B cells (CD19 and CD79A), monocytes (CD86 and CD115), TAMs (CCL2 and IL10), M1 macrophages (COX2), neutrophils (CD66b, CD11b, and CCR7), DCs (HLA-DPA1), T-helper (STAT4, STAT5A, STAT6, BCL6, and IL17A), Treg (FOXP3, CCR8, and TGFβ), and exhausted T cells (TIM-3). Here, CEACAM8 is linked to neoplasm.
