Description
HIV infected T-cell. Colored scanning electron micrograph of HIV viruses (white dots) budding from the cell membrane (blue) of an infected T-lymphocyte, a key cell of the human immune system. The AIDS virus known as HIV (Human Immuno-deficiency Virus) has genetic material in the form of RNA. It possesses an enzyme, reverse transcriptase, which enables it to subvert the DNA genetic material of the T-cell in order to replicate more viruses. Progeny of the HIV virus then bud away from the cell membrane of the host T-cell, which is ultimately destroyed. Destruction of the immune system renders AIDS victims liable to a number of fatal secondary infections. Note that the colorization is misleading HIV viruses are small dots budding from surface, and the highlighted yellow structure is just the surface of the lymphocyte.
