AIDS viruses. Coloured scanning electron micrograph of a T-lymphocyte blood cell (green) infected with Human Immunodeficiency virus (HIV) (red),causative agent of AIDS. The surface of the T-cell has a lumpy appearance with large irregular surface protrusions. Smaller spherical structures on the cell surface are HIV virus particles budding away from the cell membrane. The virus has infected the T-cell,and instructed the cell to reproduce many more viruses. By this viral budding the T- cell dies. Depletion of the number of T- cells in the blood is the main reason for the destruction of the immune system in AIDS.
