One of the main mechanisms for avoiding immune response by cancer cells is mediated by inducing an immunosuppressive environment in the tumor following activation of immune checkpoints, i.e. PD-1 or CTLA-4 receptor inhibitors on T lymphocytes. Interaction inhibition between PD-1 or CTLA-4 and their ligands (PD-L1, CD80, and CD85) leads to unblocking of the T-lymphocyte function, and thus destroys cancer cells. Certain intracellular signaling pathways are also involved in the development of tumor cell immunoresistance. Immunosuppressive pathways' activation blocking may increase the immunological anti-tumor control.
