Caption: HIV-1 virus infection. Coloured Transmission Electron Micrograph (TEM) of HIV-1, the AIDS virus, budding from the surface of an infected T- lymphocyte (T-cell). HIV-1 viruses are green; the T-cell is brown at lower frame. Two viruses are seen emerging from the cell (centre right, red). HIV-1 binds to receptors on the T-cell's membrane and injects its genetic material (as RNA) into the cytoplasm. The T-cell is then forced to reproduce HIV viruses, which bud from and damage the cell, eventually killing it. Decline in T-cell count severely compromises the immune system, exposing the host to other infections. This infection occurred in a haemophiliac suffering from AIDS.
