Once HIV enters the body, it gets attached to a type of white blood cell called T lymphocyte (which is the T cell in the human body's protection against infections). The RNA (genetic material) of the virus then gets converted to DNA (genetic material) by an enzyme that the virus produces. This viral DNA then gets incorporated into the DNA of the human cell (T lymphocyte), and remains there for the lifetime of that cell.

When you become infected with HIV, the virus attacks your CD4 lymphocytes (also called T helper or T4 cells), a type of white blood cell that is responsible for fighting certain infections (germs). ( See figure 1) The virus first attaches to the CD4 cell (1) and injects its genetic material (RNA). The RNA then instructs the CD4 cell to produce more of the virus (2). These new viruses (virions) are then released into the bloodstream (3) and the CD4 cell is destroyed. See similar questions...

Yes, you can still have a heart attack. An ICD does not prevent a myocardial infarction, which is a blocked artery causing heart muscle tissue to die. Things like exercise, improved diet, reduced stress, and other lifestyle changes suggested in a cardiac rehab program will reduce chances for a heart attack. The ICD implant will save your life 99% of the time if you have a potentially lethal episode of arrhythmia. (According to current statistics. See similar questions...

Many of the cells and molecules that carry out inflammation belong to the immune system, which consists of a brigade of specialized cells, tissues, and natural chemical substances that continually protect the body from harm. See similar questions...

Since 1992, scientists have estimated that about half the people with HIV develop AIDS within 10 years after becoming infected. This time varies greatly from person to person and can depend on many factors, including a person's health status and their health-related behaviors. Today there are medical treatments that can slow down the rate at which HIV weakens the immune system. See similar questions...

HIV (human immunodeficiency virus) is the virus that causes AIDS. This virus is passed from one person to another through blood-to-blood and sexual contact. In addition, infected pregnant women can pass HIV to their babies during pregnancy or delivery, as well as through breast-feeding. People with HIV have what is called HIV infection. Most of these people will develop AIDS as a result of their HIV infection. See similar questions...

Plaque can also produce harmful byproducts that irritate the gums, causing gingivitis, the early stage of periodontal diseases. If plaque isn’t removed daily, it will build up into a hard deposit called calculus. If plaque continues to form on top of the calculus, it can irritate the gums, and a pocket may develop between the teeth and gums. Plaque build up can eventually destroy the gums and bone that support the teeth. See similar questions...

The organs of the immune system are situated throughout the body. We know them as lymph nodes, and these are often what predominantly swell in the neck, groin, and armpit area when our bodies are under attack. Lymph is a transparent fluid containing mainly lymphocytes (small white blood cells), which bear the major responsibility for carrying out the activities of the immune system, and macrophages.

While PVC generally does not suffer from rodent attack, it does contain a component source protein plasticizer. It is only possible to "chew" a geomembrane at an edge onto which an animal can grip. The likely reason for an animal chewing a geomembrane is to obtain access to the "other side" for some other reason. See similar questions...

HIV impedes the proper functioning of the immune system which is our body's shield against disease. Individuals with the virus develop harmful conditions (called opportunistic infections) that don't usually affect other people. Some people develop symptoms shortly after being infected. For others it can take more than 10 years. See similar questions...

Natural killer (NK) cells are critical components of immune system function. Research shows that low NK cell activity is present in nearly all illnesses. NK cells defend the body against attack by foreign invaders. NK cells are non-specific, meaning they attack any target including bacteria, tumor or virally infected cells. The NK's ability to randomly attack a wide range of foreign invaders is the basis of the name "natural killer" cell. See similar questions...

No. The test for HIV can only tell you if you have been infected or not. Transmission of the virus does not necessarily occur every time exposure occurs. The only way for an individual to tell if he/she has been infected with HIV is to be tested. If you are unsure of your partner's status, you may want to consider talking to him/her about it and using protection (latex condoms or dental dams) to reduce your risk. See similar questions...

Inside your body there is an amazing "protection" mechanism called the immune system. It is designed to defend you against millions of bacteria, microbes, viruses, toxins, and parasites that are constantly trying to invade your body. The immune system is made up of numerous parts of the body, such as the thymus gland, lymph nodes, lymphocytes, and interferon, among others. See similar questions...

We do not know. Scientists have different theories about the origin of HIV, but none have been proven. The earliest known case of HIV was from a blood sample collected in 1959 from a man in Kinshasha, Democratic Republic of Congo. (How he became infected is not known.) Genetic analysis of this blood sample suggests that HIV-1 may have stemmed from a single virus in the late 1940s or early 1950s. We do know that the virus has existed in the United States since at least the mid to late 1970s. See similar questions...

HIV transmission can occur when blood, semen (including pre-seminal fluid, or "pre-cum"), vaginal fluid, or breast milk from an infected person enters the body of an uninfected person. HIV can enter the body through a vein (e.g., injection drug use), the anus or rectum, the vagina, the penis, the mouth, other mucous membranes (e.g., eyes or inside of the nose), or cuts and sores. Intact, healthy skin is an excellent barrier against HIV and other viruses and bacteria. See similar questions...

HIV is not casually transmitted, so kissing on the cheek is very safe. Even if the other person has the virus, your unbroken skin is a good barrier. No one has become infected from such ordinary social contact as dry kisses, hugs, and handshakes. See similar questions...

No. From the start of the HIV epidemic there has been concern about HIV transmission of the virus by biting and bloodsucking insects, such as mosquitoes. However, studies conducted by the CDC and elsewhere have shown no evidence of HIV transmission through mosquitoes or any other insects -- even in areas where there are many cases of AIDS and large populations of mosquitoes.

Diets rich in omega-3 fatty acids such as alpha-linolenic acid, eicosapentaenoic acid (EPA) or docosahexaenoic acid (DHA) competitively inhibit the conversion of arachidonic acid to prostaglandins by replacing the arachidonic acid with omega-3 polyunsaturated fatty acids in the cell membranes.
