HIV virus. Coloured Transmission Electron Micrograph (TEM) of AIDS viruses (yellow) budding out of a human T-cell. HIV (Human Immuno- deficiency Virus) causes AIDS (Acquired Immune Deficiency Syndrome) by damaging T-cells - white blood cells that play a crucial role in the immune system. Like other viruses,it reproduces by planting its genes in the host cell's DNA. These take over the cell,turning it into a virus- producing machine. The resulting damage to the immune system exposes the victim to a range of opportunistic infections,leading ultimately to death. Magnification unknown | |
