Infant “Functionally Cured” of HIV Infection
Researchers have reported the first “cure” of HIV in a young child. The infant underwent anti-retroviral therapy shortly after birth, and scientists say that this may have prevented the formation of “reservoirs” of the virus that make typical infections so persistent. Show More Summary
Many Patients Don’t Tell Health Care Staff They Are HIV-Positive
The treatment and care of individuals infected with HIV may be impaired, doctors say, after a study has revealed that many patients don’t tell health care providers about their infection. A significant proportion of HIV positive patients may not be disclosing their infection to NHS staff, when turning up for treatment at sexual health clinics,... [Continue Reading]
Personalized Plans Help HIV Patients Better Follow Their Treatments
Patients for many diseases can have difficulty sticking to their treatment regimens and taking their medications properly. A new study has found for HIV patients, developing a personalized plan with a health care provider significantly improves their adherence to their treatment. Show More Summary
Mutation Found in HIV That Reduces Drug Resistance
A natural but rare mutation occurring in the genome of HIV makes the virus more susceptible to drugs, researchers have discovered. The finding will help scientists understand why HIV can be drug-resistant, which could improve future treatments. Show More Summary
Sequence of HIV Genome Reveals Vaccine’s Effects
In a major breakthrough, scientists have been able to show that on a molecular level, an HIV vaccine puts observable pressure on the virus. The work reveals aspects of the virus’ biology that could help researchers develop even more effective vaccines. Scientists used genetic sequencing to discover new evidence that the first vaccine shown to... [Continue Reading]
No Detectable HIV Left in Patient After Bone Marrow Transplant and Antivirals
Anti-retroviral drugs, together with a bone marrow transplant seem to have completely eliminated HIV from the bodies of two patients, according to a new report. The ground-breaking work suggests that the immune system can be completely repopulated by the transplant, and those cells can be protected from new infection. Show More Summary
Drug Regimen Being Tested For HIV Infection Prevention
A drug called maraviroc is part of current treatments for HIV infection, and researchers are now testing whether the compound can also prevent infection. Clinical trials are underway, where HIV-negative men are given the drug or a placebo, as well as AIDS prevention counseling, with infection rates measured after about four months. Scientists are launching... [Continue Reading]
Identifying HIV Patients with Risky Behavior Essential to Prevent Spread of Virus
A one-size-fits-all approach is not sufficient to stem the spread of HIV, according to researchers. A number of scientists have proposed targeted prevention by identifying specific patient groups that have different behavior. For example,...Show More Summary
Patients With Multiple HIV Infections May Be Widespread
Being infected with multiple forms of HIV is called superinfection, and complicates treatment. A new study indicates that superinfection may be much more common that originally thought, Human immunodeficiency virus (HIV) superinfection...Show More Summary
Changing Immune System Gives Insights into HIV Infection
Research in a monkey model of HIV infection has shown that the immune system undergoes distinct changes which are correlated to resistance to the virus. The work suggests that a particular type of immune cell may help hold the virus at bay. After being infected with simian immunodeficiency virus (SIV) in a laboratory study, rhesus...

Anti-HIV Stem Cells Tested as Treatment in Mouse Models
In a new approach to the treatment of HIV, researchers have tested transplants of stem cells that fight the virus in mice. The transformed cells effectively integrate into the immune system, and develop into a population of immune cells that are not susceptible to the virus. UC Davis Health System researchers are a step closer... [Continue Reading]
HIV Not Treated Effectively in the Homeless
Progress in the treatment of HIV has flourished in the last few decades, with medications now established to prevent symptoms and transmission. A new study has found, however, that these medical advances aren’t helping those in poverty, where access to treatment is difficult, and the spread of the disease and incidence of symptoms are high....

Drug Brings HIV Out of Hiding in Immune Cells
One reason why HIV is difficult to cure is because the virus hides in a certain kind of immune cell, and isn’t sensitive to current antiviral medication. A new study shows that a drug currently used for some types of cancer can force the virus out into the open, suggesting a new tactic for treating... [Continue Reading]
Vaccinating Immune Cells Directly Can Help Ward Off HIV Infection
A technique involving isolating a patient’s own immune cells, boosting them with a vaccine, and returning them to the body can help reduce HIV infection, according to researchers. The study demonstrated the procedure was safe, and improved the efficacy of the cells’ response to the virus. Scientists from the Antwerp Institute of Tropical Medicine, Antwerp... [Continue Reading]
Studies of Immune System and HIV Reveals Mechanism Cells Use to Fight Virus
A new study in a top scientific journal reveals a key way our immune cells try and fight HIV infection. The discovery, which has important implications for treating and preventing the disease, is that a protein destroys key molecules within a cell that the virus needs to replicate. A novel discovery by researchers at NYU... [Continue Reading]
Saliva Test for HIV as Effective As Blood Tests
New research shows that a diagnostic test for HIV infection using saliva rather than drawing blood is just as accurate. The findings suggest that the saliva test could be broadly used for testing, without requiring individuals to go to public health clinics. A saliva test used to diagnose the human immunodeficiency virus (HIV), is comparable... [Continue Reading]
Discovery of Viral Protein Structure Helps Researchers Developing an HIV Antibody
One reason why the immune system fails to fight off HIV infection is because the virus coats itself with sugar molecules, preventing our antibodies from recognizing it. Researchers have now determined how these sugars are structurally linked to viral proteins, and have discovered an antibody that can bind and recognize the sugar/protein combination. HIV is... [Continue Reading]
New Molecules Designed to Get Anti-HIV Drugs Into the Brain
While HIV penetrates the brain during infection, anti-viral drugs cannot. This allows the brain to harbor the virus, and prevents an individual from ever being HIV-free. However, scientists have now developed a molecule that can penetrate the body’s normal barrier between the blood stream and the brain, potentially being able to kill the reservoir of... [Continue Reading]
Preliminary Success in HIV Vaccine Clinical Trials
A newly developed HIV vaccine is in the middle of clinical trials, and early results show that it is effective, researchers report. The vaccine is highly effective at generating an immune response, and will now be subjected to Phase II and III trials to further understand the vaccine’s activity. Phase I clinical trials developed by... [Continue Reading]
New Research Shows How HIV Infects Immune Cells
HIV infects a certain class of immune cells, called T cells during the infection process. It is the eventual destruction of these cells that lead to the symptoms of AIDS. New research has pinpointed the molecular basis behind how the virus hijacks these cells. A George Mason University researcher team has revealed the specific process... [Continue Reading]
