Exhaustion of HIV-specific T cells may be caused by chronic exposure to virus
The "exhaustion" of immune cells that target HIV appears to result from chronic exposure to the virus, specifically exposure to the particular protein segments targeted by the pathogen-killing HIV-specific CD8 T cells. view more (2008-05-06)
HIV-1 : RECOMBINATION BETWEEN TWO STRAINSFROM WIDELY DISTANT GROUPS
Scientists have known for a long time that the AIDS virus is genotypically highly variable. Two main types of the virus exist: HIV-1 and HIV-2. HIV-1, the most widespread throughout the world, can be divided into three groups (M, N and O) each of which has different genetic characteristics. Within group M, which gathers together the most frequent... view more... (2000-03-09)
Scientists glimpse a rare human antibody which protects against AIDS
Scientists have obtained their first detailed glimpse of a rare antibody, called b12, which is capable of inactivating many different strains of HIV, the virus which causes AIDS. A crystal structure of b12 has been determined by scientists working at The Scripps Research Institute, California, and the Glycobiology Institute at Oxford University,... view more... (2001-08-08)
Rapid HIV testing in the ER boosts diagnoses, screening
One in every 50 people screened for a suspected sexually transmitted infection (STI) in the Emergency Department at Henry Ford Hospital was found to be infected with HIV using a rapid blood sample screening test. view more (2008-10-27)
The release of new data from the HVTN 502 HIV vaccine study
The new analyses revealed today from the STEP HIV vaccine clinical trial are both disappointing and puzzling. At this time, the data offer no clear explanations as to why the vaccine showed no measurable efficacy or why among individuals with background immunity to the adenovirus vector, there were more HIV infections in the vaccinees as compared... view more...

Re-awakening old genes to help in the fight against HIV
A new vaginal cream containing a reawakened protein could someday prevent the transmission of HIV. view more (2009-04-28)
Extended infant antiretroviral prophylaxis reduces HIV risk during breastfeeding
In many resource-poor countries, infants born to mothers with HIV receive a single dose of nevirapine (NVP) and a one-week dose of zidovudine (ZDV) to prevent transmission of HIV from the mother to her newborn. view more (2008-06-05)
Study finds fears of HIV transmission in families with infected parent
Despite ongoing efforts to educate the public about HIV, a new study by researchers from UCLA, the RAND Corp., Harvard University and Children's Hospital Boston has found that two-thirds of families with an HIV-infected parent experience fears about spreading HIV in the home. view more (2008-11-04)
HIV positive employees face job loss and workplace discrimination
HIV positive employees face unemployment and workplace discrimination, indicates a study published ahead of print in Occupational and Environmental Medicine. view more (2007-10-03)
Male circumcision for HIV prevention and more
Three clinical trials in Africa found that adult male circumcision reduced the risk of men acquiring HIV infection from heterosexual sex by 51-60%. view more (2007-07-24)
Biology not behaviour could explain reduced risk of HIV infection for circumcised men (p 1039)
Research from India published in this week's issue of THE LANCET suggests that circumcised men could be over six times less likely than uncircumcised men to acquire HIV infection. The study also shows how the explanation for this decreased risk in circumcised men is likely to be biological rather than behavioural, with thin tissue in the foreskin... view more... (2004-03-24)
HIV-1-Positive Women At Increased Risk Of Genital Cancer
A study in this week's issue of THE LANCET suggests that women who are HIV-1 positive are at an increased risk of invasive genital cancer. Authors of the study recommend that gynaecological examination of these women should include examination of the vulva and perianal region to identify genital warts, which can lead to the development of invasive... view more...

New insights into vaccination for HIV
A group of Australian researchers at the Universities of Melbourne and New South Wales have developed new tools and paradigms to understand immune evasion from HIV. view more (2008-01-25)
Increased HIV risk for women with violent male partners (pp 1410, 1415)
South African research published in this week's issue of THE LANCET highlights how women with physically violent and controlling male partners are at an increased risk of HIV-1 infection. HIV/AIDS is more widespread among women in sub-Saharan Africa than any other population. Although violence from a male partner and relationship inequalities are... view more... (2004-04-28)
Ultra deep sequencing identifies HIV drug resistance at early stage
Rare, previously undetectable drug-resistant forms of HIV have been identified by Yale School of Medicine researcher Michael Kozal, M.D., using an innovative genome sequencing technology that quickly detects rare viral mutations. view more (2007-06-18)
European research yields guidelines for treatment of HIV-positive pregnant women and infants
New guidelines for the treatment of HIV-positive women and children are emerging from European research. The guidelines, aimed at reducing mother-to-child transmission of HIV, are to be published on 28 June 2002 as a supplement to the journal AIDS. A comparable set of guidelines for paediatric patients will be published in July 2002. Both reports... view more... (2002-06-28)
Study finds HIV protease inhibitor drugs may adversely affect the scaffolding of the cell nucleus
UCLA scientists, along with collaborators from Purdue University, have demonstrated that HIV protease inhibitors - crucial drugs for HIV treatment - block a cellular enzyme important for generating the structural scaffolding for the cell nucleus. view more (2007-07-17)
Body's anti-HIV drug explained
Humans have a built-in weapon against HIV, but until recently no one knew how to unlock its potential. view more (2008-10-13)
New study debunks misconceptions about barriers to the CDC's HIV testing recommendations
Since the Centers for Disease Control and Prevention (CDC) released revised recommendations for opt-out HIV testing in 2006, there has been significant debate around the barriers to widespread implementation of the recommendations. view more (2009-02-17)
Protecting HIV patients from Hepatitis B virus
Since the transmission of HIV and Hepatitis B virus (HBV) are so similar, individuals infected with one of these viruses are at a significantly increased risk for contracting the other. view more (2007-07-18)
