How come our bodies can't fight HIV?

I know what HIV and AIDS is, and I know how basic viruses work, but I can't find two sites that give the same answer to this question, so I'm wondering if anyone out there knows the answer?

I don't want the generic answer "it kills your immune system" so if you're going to answer, please answer in detail. Thanks in advance.

There are two main components of the immune system that are involved: Antibodies and T-cells.

T-cells are responsible for activating white blood cells to help fight off infection. These are the cells the HIV infects. Antibodies bond to the HIV virus and try to neutralize them before they can infect more cells. Unfortunately as the HIV virus replicates, there is too much virus and not enough antibodies to neutralize.

When a T-cell becomes infected with HIV, the virus "takes over" and causes it to start replicating more HIV. This eventually causes the T-cell to die. So T-cells keep dying while HIV loads keep increasing. When enough T-cells die, the infected person is considered to have AIDS.

It is particularly difficult for the immune system to fight off HIV infection for a number of reasons, including the following:

* HIV attacks the immune system itself, weakening its ability to fight back.
* HIV replicates in large quantities that are more than the compromised immune system can handle.
* HIV has the ability to mutate (change itself) very quickly, making it more difficult for the body to fight the infection.

So to summarize, our bodies *can* fight HIV for awhile. It's just a matter of time before the viral load outweighs the capabilities of our immune system.

Our bodied have no natural defense against the HIV virus. The virus enters the body and takes over the t-cell and uses it as a factory to produce more copies of the virus. The body has no way to stop the life cycle. The bodies natural response to an infection is to make more white blood cells but this only makes the virus worse. HIV medicine can stop the production of certain chemicals that the virus needs to replicate itself but because the virus hides in the body, the medicine will never completely eliminate the virus so when the medicine is stopped, the virus begins to reproduce again.

HIV, human immunodeficiency virus, attacks ur helper T cells. T cells are a type of white cell. There's normal T cellls, which eat the pathogens and invaders to the body, and there's helper T cells, which detect the invaders. the HIV attacks the helper T cells, so your body is unable to tell the big T cells to destroy pathogens and invaders. Then, your body gets sick from a little flu or other disease, and its devastating, and u die. But, its long battle, cuz the body starts out winning, cuz it originally has more Helper Ts than the HIV. Eventually though, the HIV wins, little by little, affecting your body more and more. That's why it stays dormant, because your body does have a good immune system. Then when there's way more HIV than your Helper T cells, it becomes AIDS, acquired immunodeficiency syndrome, and its an actual disease. That's when you get a little flu and die from it. It's so bad, because your body can't detect disease.

human immunodeficiency virus attacks the cells. any white blood cell that goes to attack the pathogen gets destroyed. if too many are destroyed then the body can no longer protect itself from other infections/foreign invaders.
