HIV virus. Coloured transmission electron micrograph (TEM) of a human immunodeficiency virus (HIV,upper centre). It is budding from the cell membrane of a T-lymphocyte white blood cell (T- cell,bottom) seen in section. HIV is the virus that causes AIDS (acquired immune deficiency syndrome). It does this by infecting T-cells,cells that have a vital role in the body's immune system. Like all viruses,HIV forces the infected cell to produce more viruses,which then bud off. The lack of healthy T-cells means AIDS sufferers have little defence against infection. Magnification unknown | |
