Other protumorigenic cytokines, such as GROα/β/γ, IL-8, and IL-6, are known to be secreted by cancer and stromal cells [35–39], whereas IL-2 and IL-3 are secreted from activated T cells to regulate the activity and maturation of immune cells to be able to eliminate tumor cells [40–43]. The gene discussed is CXCL8; the disease is neoplasm.
