Interleukins are a group of signalling cytokines that play crucial roles in the immune system. They are involved in various cellular normal communications and are essential for regulating immune responses, including those related to cancer and cancer immunology. They include important regulators important in tumour immunology: 1) Interleukin-2 (IL-2). IL-2 stimulates the growth and activation of T cells, which are important for recognizing and killing cancer cells. IL-2 has been used in cancer immunotherapy to enhance the immune response against tumours; 2) Interleukin-4 (IL-4). IL-4 promotes the differentiation of immune cells, such as T cells and B cells, towards a helper T cell 2 (Th2) phenotype. In cancer, IL-4 is associated with promoting tumour growth, angiogenesis and immunosuppression; 3) Interleukin-6 (IL-6). IL-6 is involved in inflammation and immune responses. In cancer, IL-6 can promote tumour growth and survival. It also contributes to immunosuppression and the development of cancer-related symptoms; 4) Interleukin-10 (IL-10). IL-10 is an immunosuppressive cytokine that can inhibit the activity of immune cells involved in antitumor responses. It plays a role in tumour evasion from immune surveillance and the development of immunosuppressive tumour microenvironments; 5) Interleukin-12 (IL-12). IL-12 stimulates the production of interferon-gamma (IFN-γ) and promotes the development of T helper 1 (Th1) immune responses. It enhances the activity of cytotoxic T cells and natural killer (NK) cells, crucial for antitumor immunity; 6) Interleukin-17 (IL-17). IL-17 is mainly associated with chronic inflammation and has therefore been implicated in promoting tumour growth in an inflammatory tumour microenvironment. It can also contribute to the recruitment of immune cells to the tumor microenvironment; 7) Interleukin-23 (IL-23). IL-23 plays a role in chronic inflammation and can contribute to tumour progression. It stimulates the production of IL-17 and other pro-inflammatory cytokines, promoting an immunosuppressive environment; 8) Interleukin-27 (IL-27). IL-27 has dual functions in cancer immunology. It can have both immunosuppressive and antitumor effects depending on the context. IL-27 can inhibit the growth and metastasis of certain tumours whilst also regulating immune responses and promoting tolerance.
