Tumor necrosis factor alpha (TNFa), also known as cachectin and TNFSF1A, is the prototypic cytokine of the the TNF superfamily, and is a multifunctional molecule involved in the regulation of a wide spectrum of biological processes including cell proliferation, differentiation, apoptosis, lipid metabolism, and coagulation. TNFa is produced mainly by macrophages, and large amounts of this cytokine are released in response to lipopolysaccharide, other bacterial products, and Interleukin-1 (IL-1). TNFa is primarily produced as a 26 kDa type II transmembrane protein arranged in stable homotrimers, and a 55 kDa soluble trimeric form of TNFa is released via proteolytic cleavage by the metalloprotease TACE/ ADAM17. Two receptors mediating the TNFa function have been identified, the ubiquitous TNFRI from which most signaling are derived, and the hematopoietic cell-restricted TNFRII. Upon the TNFa trimers binding, TNF receptors also form trimers, undergo a conformational change, and enable the adaptor protein TRADD to bind to the death domain, and thus initiates the signal pathways such as the NF-kB, Jak/STAT, and the MAPK pathways, as well as the death signaling. As a major mediator of apoptosis, inflammation and immunity, TNFa has been implicated in the pathogenesis of a variety of diseases including autoimmune diseases, insulin resistance, and cancer.
