AIDS virus. Computer illustration of a human immunodeficiency virus (HIV). HIV causes AIDS (acquired immune deficiency syndrome) by infecting the T-lymphocyte white blood cells (T-cells) of the immune system. The outer envelope (yellow) of the virus is studded with surface proteins (blue) that allow HIV to grab onto and sneak into the T- cells. HIV then instructs them to make more viruses which bud away from the cells,ultimately killing them. With fewer T-cells,the patient becomes vulnerable to formerly harmless infections,a condition known as AIDS | |
