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 ...

Living with HIV: Chad's JourneyFeb 17, 2012
Chad's HIV diagnosis came along with some personal challenges. Rather than allow them to stand in his way, he faced those challenges head on and broke through to a renewed life of family and community support, activism and self-care. He is on a mission to make a difference in other people's lives. Chad volunteers with TPAN and Chicago House and Social Service Agency in Chicago.

Did I Just Contract HIV? Signs and Symptoms of HIVFeb 16, 2012
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 ...

HIV Research: Seeking Solutions in Africa (HD version)Feb 21, 2012
More than 1.8 million people die of HIV-related causes each year—approximately 5000 deaths per day. HIV is a particularly significant threat in the sub-Saharan region of Africa. Researchers in South Africa and Boston are working with Microsoft Research to fight HIV. The effort is led by Bruce Walker, director of the Ragon Institute at Massachusetts General Hospital, MIT and Harvard, and a professor of medicine at the University of KwaZulu-Natal. He is joined by David Heckerman, Distinguished Scientist, Microsoft Research, who explains that as our immune system tries to block HIV, the virus mutates to evade the immune system. The researchers are cataloging fragments of HIV that are vulnerable to attack by the immune system. The amount of data generated is enormous, but by using thousands of Microsoft machines working in parallel, researchers are able to make computations in a matter of hours that would take years on a single computer. Through research like this, Walker believes that a solution to the HIV epidemic can be developed. Like many other dedicated researchers, he is devoting his career to finding such a solution.
Living with HIV: Hattie's JourneyFeb 18, 2012
When Hattie learned she was HIV positive, it took some time for her to overcome the stigma that came with the diagnosis. With the help of family and friends, she was able to realize all she had to live for and now faces each day with the support of her loved ones -- and a lot of laughter. Hattie works with the AIDS Service Center in New York, NY.

HIV/AIDS vaccine developed at Western proceeding to human clinical trialsFeb 17, 2012
London, Ontario CANADA --The first and only preventative HIV vaccine based on a genetically modified killed whole virus has received approval by the United States Food and Drug Administration (FDA) to start human clinical trials. Developed by Dr. Chil-Yong Kang and his team at The University of Western Ontario, with the support of Sumagen Canada, the vaccine (SAV001) holds tremendous promise, having already proven to stimulate strong immune responses in preliminary toxicology tests with no adverse effects or safety risks. It is the only HIV vaccine currently under development in Canada, and one of only a few in the world.
