This process involves several molecular and cellular components consisting of lipid inflammatory mediators (leukotriene, prostaglandin, etc.)and cytokines (IFNγ, TNFα, IL2, IL12, etc.), as well as chemokines (CCL20, CXCL10, CCL22, CCL17, etc.), that are released by various proinflammatory cells such as T helper (Th)1, Th17, Th9, Th22, monocytes, macrophages, dendritic cells, and cancer cells themselves [6, 13, 15, 17–19]. The gene discussed is TNF; the disease is cancer.
