How does the human immunodeficiency virus cause AIDS?

Attacks T cells. T lymphocytes, part of the white blood cells, are the main cells in the specialized immune system, Especially the T helper cells, so when attacked the HIV virus, the whole immune system becomes deranged, hence the development of AIDS,

In addition to causing aids, we now know that HIV also increases chronic inflammation and immune activation, which can increase the risk of complications like coronary heart disease, malignancies, decreased bone density, and cognitive dyfunction. There is a lot of interest now in HIV as a cause of earlier complications of the aging process. Read more...

What symptoms are caused by the human immunodeficiency virus?

Many and few. At the outset the patient infected may not even be aware of the presence of the virus, and this can persist until the immune system is badly damaged, and secondary infections or cancers occur (8-12 yrs). Sometimes, acute HIV syndrome will present as a mononucleosis-type illness with multiple symptoms. Best thing to do is get checked and tested if you feel you have been exposed. Read more...

Sharing body fluids. Hiv is a sexually transmitted infection. It can also be spread by contact with infected blood, or from mother to child during pregnancy, childbirth or breast-feeding. It can take years before HIV weakens the immune system to the point that the patient has aids. There is no cure for hiv/aids, but there are medications that can dramatically slow the progression of the disease. Read more...

How is the human immunodeficiency virus (hiv) transmitted to heterosexuals?

Same as heterosex.

There are some forms of sexual activity in which individuals are more prone to bleeding, in which case these bleeding sites present a rapid route for viral entry. Read more...

The human immunodeficiency virus (hiv) infects helper t cells. What is the role of these cells?

Cellular immunity. These are cells that work as part of the cellular immune system, fighting certain fungal (e.g. Cryptococcus), viral (e.g. Herpesviruses), parastic (e.g. Toxoplasma), and bacterial (e.g. Tuberulosis) infections. The cellular immune system also helps to prevent certain cancers, such as lymphomas. Read more...

What are proteins found in the human immunodeficiency virus?

HIV proteins. Hiv particles surround themselves with a coat of fatty material known as the viral envelope (or membrane). Projecting from this are around 72 little spikes, which are formed from the proteins gp120 and gp41. Just below the viral envelope is a layer called the matrix, which is made from the protein p17.
