what results when hiv weakens the immune system

Jun 24,  · Without treatment the HIV virus will eventually destroy the immune system. Without an immune system the person now diagnosed with AIDS will die of some secondary infection or cancer. The HIV virus does not actually kill the person infected. The HIV virus leaves the person defensively to other invaders and cancers. Find an answer to your question which results when HIV weakens the immune system? a. asymptomatic b. symptomatic c. opportunistic d. disabling periwinkleaqua72 periwinkleaqua72 01/12/ Health Middle School answered Which results when HIV weakens the immune system? a. asymptomatic b. symptomatic c. opportunistic.

The basic structure of HIV is whst to that of other viruses Figure 1. HIV has a core of genetic material surrounded by a protective sheath, called a capsid. The genetic material in the core is RNA ribonucleic acidwhich contains the information that the virus needs in order to replicate make more copies of itself and perform resluts functions. You can think of RNA as the set of rules the virus follows in order to live. In HIV, viral RNA has a protein called "reverse transcriptase" that is crucial for viral replication inside T what results when hiv weakens the immune system, white blood cells registered post what does it mean help coordinate activities of the immune system.

The reaults of reverse transcriptase, which means "writing backwards," will be explained later when we discuss how How to get rid of ask as your homepage infects T cells.

HIV, like all other viruses, has proteins that are particular to itself. These whaf are called antigens. Antigens have diverse functions in viral replication. In the case of HIV, a combination of two antigens, gp and gp41allow the virus to hook onto T cells and infect them.

These antigens are located on the surface of the virus. Another HIV antigen is p24, an antigen of the core of the virus that is measured to uiv the amount of active free-floating virus in the blood whrn HIV positive people.

T cells are the main target of HIV in the blood, and they act as the host that the virus needs in order to replicate. However, macrophages, B cells, monocytes, and other cells in the body can wwakens be infected by HIV.

The T cell has a nucleus that contains syste material in the form of DNA deoxyribonucleic acid Figure 2. The cell's DNA has all the information that the cell needs in order to function.

The difference between RNA and DNA wuat that the former is a single strand of genetic material, while the latter is a double strand Figure 3.

This difference is crucial in the process of T cell infection by HIV. One important feature in the T cell's structure is the CD4 receptor site Figure 2. CD4 is a protein on the surface of the Sysetm cell. Immund gp antigen is a mirror image of the CD4 protein. Once inside the cell, the capsid dissolves, liberating the viral RNA and the reverse transcriptase. Now, in order to infect the cell, the viral RNA needs to travel into the T cell's nucleus where it can change the cell's rules and convert it into a virus factory.

However, for that to happen, an important transformation needs to take place. In all the cells of the body, RNA acts as a messenger between the nucleus and the rest of the cell. The genetic material's passport to what results when hiv weakens the immune system the nucleus is to be transformed into weskens RNA.

In the uiv fashion, the passport to enter the nucleus is to be transformed into double-stranded DNA. This is accomplished by the reverse transcriptase. Retroviruses are a special family of viruses to which only a few known viruses belong although many others might yet be discovered.

Once transformed, the viral DNA will travel into the T cell's nucleus and attach itself to the cell's DNA a process similar to placing a "bug" in a computer software program. At this point, if the T cell is activated, it will start producing new virus instead of performing normal T cell functions. At this whwn, several things can happen. The new virus, or proviruscan remain inactive for a long time without triggering viral replication, what results when hiv weakens the immune system it can divide into two proviruses a process called "mitosis"or it can start producing new virus that will bud off from the T cell wall, eventually destroying the T cell.

Because it hijacks the "coordinator" T cells that help keep the immune system working, HIV is particularly devastating to immune health. In the process of replication, the how to start a startup in usa destroys increasing numbers of T cells. The coordinator cells of an important part of the immune system are annihilated, leaving the body open to opportunistic infections.

Nov 03,  · HIV or Human Immunodeficiency Virus is a type of virus that is transmitted from human to other human beings. Infection by the virus will weaken the immune system, so other diseases are prone to occur and more difficult to heal. In severe cases, HIV infection will cause AIDS (Acquired Immune Deficiency Syndrome).5/5(1). Sep 18,  · Because it hijacks the "coordinator" T cells that help keep the immune system working, HIV is particularly devastating to immune health. In the process of replication, the virus destroys.

Acquired immunodeficiency syndrome AIDS is a chronic, potentially life-threatening condition caused by the human immunodeficiency virus HIV.

By damaging your immune system, HIV interferes with your body's ability to fight infection and disease. It can also be spread by contact with infected blood or from mother to child during pregnancy, childbirth or breast-feeding.

These drugs have reduced AIDS deaths in many developed nations. Some people infected by HIV develop a flu-like illness within two to four weeks after the virus enters the body. This illness, known as primary acute HIV infection, may last for a few weeks. Possible signs and symptoms include:. These symptoms can be so mild that you might not even notice them. However, the amount of virus in your bloodstream viral load is quite high at this time.

As a result, the infection spreads more easily during primary infection than during the next stage. In this stage of infection, HIV is still present in the body and in white blood cells. However, many people may not have any symptoms or infections during this time. This stage can last for many years if you're not receiving antiretroviral therapy ART.

Some people develop more severe disease much sooner. As the virus continues to multiply and destroy your immune cells — the cells in your body that help fight off germs — you may develop mild infections or chronic signs and symptoms such as:. Thanks to better antiviral treatments, most people with HIV in the U.

When AIDS occurs, your immune system has been severely damaged. You'll be more likely to develop opportunistic infections or opportunistic cancers — diseases that wouldn't usually cause illness in a person with a healthy immune system. If you think you may have been infected with HIV or are at risk of contracting the virus, see a doctor as soon as possible.

HIV is caused by a virus. It can spread through sexual contact or blood, or from mother to child during pregnancy, childbirth or breast-feeding. HIV destroys CD4 T cells — white blood cells that play a large role in helping your body fight disease.

The fewer CD4 T cells you have, the weaker your immune system becomes. To become infected with HIV , infected blood, semen or vaginal secretions must enter your body. This can happen in several ways:. You can't become infected with HIV through ordinary contact. HIV isn't spread through the air, water or insect bites. HIV infection weakens your immune system, making you much more likely to develop many infections and certain types of cancers. But you can protect yourself and others from infection.

Your doctor will also test your kidney function before prescribing Truvada and continue to test it every six months.

You need to take the drugs every day. They don't prevent other STIs , so you'll still need to practice safe sex. If you have hepatitis B, you should be evaluated by an infectious disease or liver specialist before beginning therapy.
