Detailed description

TNF is primarily produced by macrophages, the immune system’s scavenger cells. Its name is derived from the fact that the molecule is able to kill certain tumor cells by inducing the so-called necrosis. It can also trigger proliferation and differentiation of cells as well as cell death. TNF causes and boosts inflammation, which serves to fight an infection. In case of chronic inflammations there is, however, too much TNF so that it has to be inhibited with medication.
