How AIDS attack the cell ?



HIV is the virus that causes AIDS

Once HIV succeeds in getting into the human body, it immediately searches for the T-cells.
The AIDS virus, like a wolf disguised in sheep skin, attaches itself to the T-cell which mistakes it for something familiar.

It then fuses its surrounding membrane with that of the host cell.

Once the virus is in the T-cell, the viral DNA will enter the T-cell's nucleus and become part of its genetic composition. The T-cell is now unable to recognize foreign substances.
The cell begins to reproduce the altered DNA, it actually becomes a factory for procreating its own foe. However, HIV is able to reproduce itself a thousand times faster than any other virus.

Once the cell is overused, the viruses EXPLODES out of it, ready to attack other T-cells. Ironically the cells which are supposed to fight infection against the body are the very ones which destroy it.
