lncRNA T cell leukemia/lymphoma 6 (TCL6) positively correlates with tumor-infiltrating lymphocyte (TIL) infiltration and immune checkpoint molecules such as cytotoxic T-cell lymphocyte-associated protein 4 (CTLA-4), programmed death receptor 1 (PD-1), and its ligand (PD-L1) (Zhang et al., 2020b). This evidence concerns the gene TCL6 and neoplasm.
