| TNF |
A cytokine, produced by macrophages, which helps activate T cells. It may also stimulate HIV activity. TNF levels are very high in persons with HIV, and the molecule is suspected to play a part in HIV-related wasting, neuropathy, and dementia. TNF triggers a biochemical pathway that leads to the programmed form of cell suicide known as apoptosis. It also activates a key molecule that can block this very pathway, and so set up a delicate life-death balance within the cell.
