Tumor cells and immune system

The phrase “tumor cells and immune system” does not refer to a specific molecule, receptor, or actionable biological target, but rather describes the complex interplay between malignant cells and the diverse components of the immune system within the tumor microenvironment. This includes direct contact, cytokine-mediated signaling, antigen presentation, immune evasion, and modulation involving various immune cell types (such as macrophages, T cells, dendritic cells, and myeloid-derived suppressor cells) and tumor-derived factors. Research in this area is vital for understanding cancer progression and developing immunotherapies, but “tumor cells and immune system” is too broad and unspecific to be a canonical drug target or molecular entity.
