Recently, the CDC (Center for Disease Control) issued a statement that all Baby Boomers should be tested for Hepatitis C. The question often comes up as to why this particular segment of people is so vulnerable. What does being born between 1945 and 1965 have to do with Hepatitis C? What was di...
Buyer Beware! There are several snake oil salesmen out there who are claiming to have cured their own Hepatitis C with herbs, supplements and parking lot gravel. Okay, maybe not the parking lot gravel but it might as well be. What you need to remember is that there are two different types of...

Helper T-cells normally support the immune system, but a new study involving mice shows HIV-infected T-cells help transport the virus throughout the body and infect other T-cells.
Researchers from Massachusetts General Hospital said their findings could lead to improved treatments that could help control the movement of infected T-cells in the body.
"We have found that HIV disseminates in the body of an infected individual by 'hitching a ride' on the T-cells it infects," study author Dr. Thorsten Mempel, of the Massachusetts General Hospital Center for Immunology and Inflammatory Diseases, said in a hospital news release.
The researchers examined the behavior of HIV-infected human T-cells using a "humanized" mouse model, which has an essentially human immune system, according to the release.
After confirming that human T-cells enter and migrate within the animals' lymph nodes, the researchers injected them with HIV engineered to give off a green fluorescent protein, which allowed them to monitor the movement of infected cells.
They found that within two days, the HIV-infected T-cells moved more slowly than healthy T-cells. They also were evenly distributed within the lymph node, but they remained close to the injection site.
"Infected T-cells continue doing what they usually do -- migrating within and between tissues such as lymph nodes -- and in doing so they carry HIV to remote locations that the virus could not reach as easily," Mempel said. "There are drugs that can manipulate the migration of T-cells that potentially could be used to help control the spread of virus within a patient."
Ten percent to 20 percent of the HIV-infected T-cells formed long, thin extensions that trailed behind the moving cells. These elongated cells contained the HIV envelope protein, which researchers thought might cause infected cells to "tether" to uninfected cells and form these extensions.
Infected cells had multiple nuclei, the researchers found, which shows they were formed when several cells combined.
The researchers also injected a separate group of mice with HIV. This group, however, was treated with an agent that prevents T-cells from leaving the lymph nodes.
After two months, the researchers found the levels of HIV in the animals' blood and in lymph far from the injection site were much lower than the levels of the animals not treated with the agent. They noted that the agent used to suppress the migration of infected T-cells did not reduce the level of HIV in animals that already had an established HIV infection.
"While our observation of tethering interactions between infected and uninfected ... cells suggests that HIV may be transmitted between T-cells by direct contact, we will have to clearly show this in future studies and explore how important it is relative to the transmission by free virus," said Mempel, who also is an assistant professor of medicine at Harvard Medical School in Boston.
The study was published Aug. 1 in the journal Nature. Scientists note that research with animals often fails to produce similar results in humans.
Please sign the ATC Salvage Therapy Petition Join us in asking Congressman Alcee Hastings and Congresswomen Maxine Waters to send a ‘Dear Colleague’ letter to Anthony Fauci, Director of NIAID, asking for the federal facilitation of apricitabine (ATC).

It works against viruses that are resistant to several other nukes and could ...
Researchers from Johns Hopkins Children’s Center, the University of Mississippi Medical Center and the University of Massachusetts Medical School announced today at CROI2013 the discovery of the first infant functionally cured of HIV. The baby, a female now two and a half years old, received 3 HIV medications when brought to the hospital at 30 hours old. Viral load tests were performed during the first few weeks that showed a rapidly decreasing viral load which reached ...
At the 19th International AIDS Conference (AIDS 2012) in Washington D.C., the CDC reported that only 1 out of 4 HIV patients in the U.S. have HIV under control, which is defined as complete viral suppression. Warning bells should be ringing in the scientific and HIV advocacy communities. While much progress has been made in the last three decades in the treatment of HIV, tens of thousands of people living with HIV (PLWH) are currently struggling to construct viable treat...

The HIV community has been abuzz with the August FDA approval of what had been termed “the Quad”, the second one-pill-once-a-day combination antiretroviral drug. Marketed by Gilead under the name Stribild, the drug contains two NRTIs (tenofovir and emtricitabine), an integrase inhibitor (elvitegravir) and an integrase booster (cobicistat) and is approved for use in treatment naïve patients with either drug resistant or wild type virus. In comparison to Atripla, the first...

Mission Statement
At HIV Haven we wish to provide our readers with vital cutting edge information to help expand HIV knowledge and promote activism, particularly that which works towards an end to the HIV pandemic. It is our desire to bring to you the scientific, medical and social advances that given the appropriate attention and support, could change the course of the HIV pandemic, lessen the devastating effects of HIV and AIDS, better the quality and quantity of life for people living with HIV and even yield an eventual end to the HIV pandemic. We also provide the basics of HIV transmission and treatment.
We will focus on issues such as innovative drug development, strategic activist campaigns, HIV relationships and novel HIV and HIV cure research. We also will bring you advances in Hepatitis C (HCV), a common HIV co-infection. Whether you are living with HIV/AIDS, HIV and HCV, love someone who is, are an activist, advocate, researcher, physician or just an interested party, we hope here at HIV Haven we can help you find what you are looking for.
