Each step is crucial to successful replication and is therefore a potential target of antiretroviral drugs. Step one is the infection of a suitable host-cell, such as a CD4-positive T-lymphocyte. Entry of HIV into the cell requires the presence of certain receptors on the cell surface, CD4 -- receptors and co-receptors such as CCR5 or CXCR4. These receptors interact with protein-complexes, which are embedded in the viral envelope. These complexes are composed of two glycoproteins: an extracellular gp 120 and a transmembrane gp 41 When HIV approaches the target cell gp120 binds to the CD4-receptors. This process is termed attachment. It promotes further binding to a co-receptor. Co-receptor binding results in a conformational change in gp120. This allows gp41 to unfold and insert its hydrophobic terminus into the cell membrane. Gp 41 then folds back on itself. This draws the virus towards the cell and facilitates the fusion of their membranes. The viral nucleocapsid enters the host cell and breaks open releasing two viral RNA-strands and 3 essential replication enzymes: Integrase, Protease and Reverse Transcriptase. Reverse Transcriptase begins the reverse transcription of viral RNA. It has two catalytic domains: The Ribonuclease-H active site And the polymerase active site Here single stranded viral RNA is transcribed into an RNA-DNA double helix. Ribonuclease- H breaks down the RNA. The polymerase then completes the remaining DNA-strand to form a DNA -- double helix. Now Integrase goes into action. It cleaves a dinucleotide from each 3-prime end of the DNA creating two sticky ends. Integrase then transfers the DNA into the cell nucleus and facilitates its integration into the host cell genome. The host cell genome now contains the genetic information of HIV. Activation of the cell induces transcription of proviral DNA into messenger RNA. The viral messenger RNA migrates into the cytoplasm where building blocks for a new virus are synthesised. Some of them have to be processed by the viral protease. Protease cleaves longer proteins into smaller core proteins. This step is crucial to create an infectious virus. Two viral RNA-strands and the replication enzymes then come together and core proteins assemble around them forming the capsid. This immature particle leaves the cell acquiring a new envelope of host and viral proteins. The virus matures and becomes ready to infect other cells. HIV replicates billions of times per day destroying the hosts` immune cells and eventually causing disease progression. Drugs which interfere with the key steps of viral replication can stop this fatal process. Entry into the host cell can be blocked by fusion inhibitors for example. Inhibition of reverse transcriptase by nucleoside inhibitors or by non-nucleoside Reverse Transcriptase- inhibitors is part of standard antiretroviral regimens. The action of Integrase can be blocked. Protease inhibitors are also part of standard antiretroviral therapy. Each blocked step in viral replication is a step towards better control of HIV disease.

It's sometimes possible to recognize when you've recently contracted HIV from signs and symptoms such as fever, rash, or swollen lymph nodes. This video will teach you how to recognize signs and symptoms of primary HIV infection that are experienced by between 40 and 90% of individuals after they are first infected with HIV. Primary HIV infection occurs during the first few weeks or months after a person first becomes infected with HIV. Symptoms include rash and/or fevers, possibly in combination with one or more of the following symptoms: malaise (which is a general feeling of weakness, discomfort, and fatigue), loss of appetite, weight loss, a sore throat, sores in the mouth, joint or muscle pain, swollen lymph nodes, diarrhea, fatigue, night sweats, nausea and vomiting, headache, or genital sores. The symptoms usually last from seven to ten days, and rarely more than two weeks. There is an incubation period of a few days to a few weeks between when the person was exposed to HIV and when the symptoms begin. If you have any of these symptoms and think there's even the slightest chance you might have been exposed to HIV, such as through recent sexual activity or sharing a needle, even with someone who you believe is HIV negative, you should see a doctor and ask to be tested for HIV. When you go to the doctor with any of these symptoms, it's very important to mention any risk factors you may have for HIV so they could test you. If you have ever had unprotected sex, even once, have used injection drugs, or think you might be experiencing primary HIV infection, make sure to tell your doctor.

Process of HIV virus cell entry.

Two doctors in Houston, Texas, believe they might have discovered the Achilles heel of the HIV virus. KHOU's Lee McGuire reports.

For its exhibit at the 2002 International AIDS Conference in Barcelona,GlaxoSmithKline commissioned a three minute film on the life of cycle of the HIV virus,with an emphasis on the mechanism of the integrase molecule in its role in inserting the AIDS virus genome into the host T-cell DNA.

Becky Kuhn, M.D., co-founder of Global Lifeworks, covers critical basic information about HIV and AIDS. HIV is a virus that causes the disease AIDS, which can be fatal. There are treatments but no cure. HIV is spread by contact between body fluids (blood, semen, vaginal fluids, and breast milk) and mucous membranes (eyes, nose, mouth, and genitals). It is spread by sexual contact, injection drugs users sharing needles, from mother to child during childbirth or nursing, and (early on during the epidemic) by receiving blood transfusions. You can reduce your risk by abstaining from sex before marriage, being faithful to a single partner and using a condom and/or dental dam if you are sexually active, and by never injecting drugs or by never sharing needles if you do. It can take up to six months after exposure to HIV for a person to test HIV positive; even before they test HIV postive, the infected person can spread the disease to others. A doctor can prescribe antiretroviral (ARV) drugs to prevent HIV from progressing to clinical AIDS. It is critical to take every ARV dose on schedule to avoid developing a resistant strain of HIV. If a person is HIV positive, they still need to practice safer sex to avoid spreading HIV to others and to avoid contracting a different, resistant strain of HIV.

Becky Kuhn, M.D., co-founder of Global Lifeworks, debunks the following 10 myths about HIV: HIV doesn't cause AIDS; because of ARV medications, we no longer need to be concerned about HIV/AIDS; if you have HIV and are sexually active, you no longer need to practice safer sex; you can't contract HIV through oral sex; you can't get HIV from one sexual encounter; a woman cannot spread HIV to another woman by having sex with her; if you are HIV positive but your viral load is undetectable, you cannot spread HIV; AIDS can be spread by kissing, hugging, or shaking hands; if you have HIV, you can cure it by having sex with a virgin; every individual with HIV will eventually develop AIDS.

http://www.whale.to/vaccines.html [Video] Bayer Sells AIDS-Infected Drug Banned in U.S. in Europe, Asia - Unearthed documents show that the drug company Bayer sold millions of dollars worth of an injectable blood-clotting medicine -- Factor VIII concentrate, intended for hemophiliacs -- to Asian, Latin American, and some European countries in the mid-1980s, although they knew that it was tainted with AIDS. Bayer knew about the fact that the drug was tainted and told the FDA to keep things under wraps while they made a profit off of a drug that infected its patients. If these allegations are true, then both Bayer and the FDA are at fault for this catastrophe. FDA regulators helped to keep the continued sales hidden, asking the company that the problem be ''quietly solved without alerting the Congress, the medical community and the public,'' according to the minutes of a 1985 meeting octomedia Vaccine Information and Awareness sites: http://thinktwice.com/ http://www.vaclib.org/

Stigma and discrimination are fueling the HIV epidemic in the Caribbean. In Jamaica, those living with HIV often face social isolation and harassment. Stigma also stops at-risk people from seeking information on prevention and testing, altering their sexual behavior, and accessing counseling, support groups and treatment. In this video, Kwame Dawes talks about HIV-related stigma with people living with the disease and those at risk of contracting HIV. An extended essay by Kwame Dawes on HIV/AIDS in Jamaica is featured in the Spring 2008 issue of the Virginia Quarterly Review: www.vqronline.com A synthesis of video, photographs, poetry and music, all inspired by Kwame's reporting in Jamaica, can be found on the interactive site: www.livehopelove.com Credits: Special Correspondent Kwame Dawes Co-Producers Nathalie Applewhite Stephen Sapienza Videographers Nathalie Applewhite Doug Gritzmacher Stephen Sapienza Production Assistants Janeen Heath Chris Thompson Glendon Asphal Darren Scott Produced by Pulitzer Center on Crisis Reporting

Fight AIDS. Fight TB. Fight Now...A film co-produced by UNAIDS and the Stop TB Partnership. Discusses TB, a leading killer among HIV-infected people with weakened immune systems.

AIDS stands for acquired immunodeficiency syndrome, a disease that makes it difficult for the body to fight off infectious diseases. The human immunodeficiency virus known as HIV causes AIDS by infecting and damaging part of the body's defenses against infection, namely the white blood cells known as CD4 helper lymphocytes (pronounced: lim-fuh-sites). The only known way for HIV to be transmitted from one person to another is when it is spread from the inside of an infected person's body to the inside of another person's body. This can happen when infected fluids - such as semen (also known as "cum," the fluid released from the penis when a male ejaculates), vaginal fluids, or blood - are passed from one person to another. A person can become infected even if only tiny amounts of these fluids are spread. How does someone become infected? HIV can be spread through sexual intercourse if one of the partners has the virus. The virus can be spread through an infected person's blood, semen, and secretions from the cervix (part of a female's uterus) or vagina. HIV can travel to another person through cuts and sores on the penis, rectum (the last part of the intestine that connects to the anus), vagina, or skin around the genitals and probably the mouth and other mucous membranes. These cuts or sores are often so small that a person isn't even aware of them. Girls and guys who have a discharge (an abnormal fluid coming from the vagina or penis) or genital sores because they have a sexually transmitted disease are at increased risk for infection. HIV can be spread sexually from a man to a woman, a woman to a man, a man to a man, and a woman to a woman. People who inject themselves with drugs also risk infecting themselves with HIV. Many people who use needles to take intravenous drugs or steroids share the needles with others. If a person with HIV shares a needle, he or she also shares the virus, which lives in the tiny amounts of blood attached to the needle. Sharing needles can also pass hepatitis and other serious infections to another person. Also, a newborn baby is at risk of getting the HIV virus from his or her mother if she is infected. This can happen before the baby is born, during birth, or through breastfeeding. Pregnant teens and women should be tested for HIV because infected women who receive treatment for HIV are much less likely to spread the virus to their babies. Babies born to mothers infected with HIV are also given special medicines to try to prevent HIV infection

This stunning censored interview conducted by medical historian Edward Shorter for WGBH public television (Boston) and Blackwell Science was cut from The Health Century due to its huge liability--the admission that Merck drug company vaccines have traditionally been injecting cancer viruses (SV40 and others) in people worldwide. This segment of In Lies We Trust: The CIA, Hollywood & Bioterrorism, produced and freely contributed by consumer protector and public health expert, Dr. Leonard Horowitz, features the world's leading vaccine expert, Dr. Maurice Hilleman, who explains why Merck's vaccines have spread AIDS, leukemia, and other horrific plagues worldwide. Please forward this clip (link) to everyone you know who thinks vaccines are "safe and effective."

AZT is a type of chemotherapy that was halted as a treatment for cancer because it was too deadly. Not wanting to lose money by tossing out the drug, drug companies then decided to promote it for AIDS. What would you expect to happen to cancer patients if they received chemo permanently? That is exactly what's happening to AIDS patients who take AZT; they get daily chemo until it kills them. Maybe you've never heard, but there are credible scientists who question the mainstream stance on HIV and AIDS. Something very convincing that they could be right is the growing number of people who are HIV+ yet healthy for 25+ years. I personally have seen "full blown AIDS" patients recover when a high quality nutritional supplement was introduced. Conversely, patients who take AIDS medications such as AZT usually become rapidly ill and believe it is due to their condition, when it is actually the drug. My research and experience have taught me that AIDS can only occur when the immune system is suppressed. This is often due to drugs, including prescription drugs (such as the immunosuppressive drugs given to hemophiliacs). AIDS patients who were ill have totally reversed their decline and become incredibly healthy through proper nutrition and exercise. Even HIV test kits say they can't be used to detect the presence of the virus, so why are these people being labeled and given a death sentence?
