AIDS research. Tubes of chimpanzee blood infected with SIV (Simian Immunodeficiency Virus), an animal AIDS virus. The blood has been centrifuged and its constituent parts are separated in layers: clear plasma, layer of white blood cells, and red blood cells (at bottom). T-lymphocyte white blood cells are attacked by the AIDS virus. Research on SIV, similar to HIV (Human Immunodeficiency Virus) is being conducted to understand the syndrome of AIDS in humans. This study may help to produce a vaccine against AIDS or more effective AIDS drugs. Photographed at the Pasteur Institute in Paris.
