"A dynamic three-dimensional model depicts human immunodeficiency viruses (the cause of AIDS) ecaping from an infected white blood cell. As they emerge from the cell surface, the viruses (yellow and gold spheres) acquire a membrane envelope studded with special potein receptors. These receptors act somewhat like a key for viruses to unlock and gain entrance to the next host cell. The red background medium represents the circulating blood, an important factor in the transmission of AIDS."--
