Tumour Necrosis Factor α （TNFα）, is an inflammatory cytokine produced by macrophages/monocytes during acute inflammation and is responsible for a diverse range of signalling events within cells, leading to necrosis or apoptosis. The protein is also important for resistance to infection and cancers. In view of these facts, TNF-α has been recommended as an important target for discovering drugs for autoimmune and inflammatory diseases and cancer.
