HIV
Today, during the 87th General Session of the International Association for Dental Research, convening at the Miami Beach Convention Center, a group of scientists from Nihon University (Tokyo, Japan) will present findings suggesting that periodontal disease could act as a risk factor for reactivating latent HIV-1 in affected individuals.
Seattle - A study showing improved survival of starting antiretroviral treatment earlier than current U.S. recommendations is being reported in the April 30 issue of the New England Journal of Medicine. The study found that not starting HIV patients at a CD4 count greater than 500 cells per cubic millimeter increased risk of death by 94 percent.
A potential treatment for HIV may one day help people who are not responding to Anti-Retroviral Therapy, suggests new research published tomorrow in The Journal of Immunology.
Drug-resistant forms of HIV can be spread between individuals who have not received anti-retroviral treatment, according to Professor Deenan Pillay from University College, London and the Health Protection Agency, speaking at the Society for General Microbiology meeting at Harrogate today, (Monday 30 March).
A research team at the Scripps Research Institute has obtained the first glimpse of a protein that keeps certain substances, including many drugs, out of cells. The protein, called P-glycoprotein or P-gp for short, is one of the main reasons cancer cells are resistant to chemotherapy drugs. Understanding its structure may help scientists design more effective drugs.
Researchers at the Tulane University School of Medicine, New Orleans, Louisiana have discovered that the HIV-1 protease inhibitors (PIs), such as nelfinavir included in highly active antiretroviral therapy (HAART) regimen for the treatment of HIV-1 patients, induce deleterious effects on insulin secretion mediated through the oxidative stress pathway.
Increased schooling across sub-Saharan Africa may be lowering new HIV infections among younger adults, according to sociologists, suggesting a shift in a decades-long trend where formal education is considered an AIDS risk factor.
HAART (highly active anti-retroviral therapy) has emerged as an extremely effective HIV treatment that keeps virus levels almost undetectable; however, HAART can never truly eradicate the virus as some HIV always remains dormant in cells.
Many scientists believe a vaccine that prevents HIV infection will need to stimulate the body to make neutralizing antibodies, infection-fighting proteins that prevent HIV from entering immune cells. Previous research has shown that some individuals who control HIV infection without medication naturally produce antibodies able to neutralize diverse strains of HIV.
For 25 years, researchers have tried and failed to develop an HIV vaccine, primarily by focusing on a small number of engineered "super antibodies" to fend off the virus before it takes hold. So far, these magic bullet antibodies have proved impossible to produce in people.
March 5, 2009 -- A clinical trial involving more than 3,000 women in the U.S. and southern Africa demonstrates for the first time the promise of a vaginal microbicide gel for preventing HIV infection in women.
The human immunodeficiency virus (HIV) adapts so well to the body's defense system that any successful AIDS vaccine must keep pace with the ever-changing immunological profile of the virus, according to researchers at the University of Alabama at Birmingham (UAB) and the University of Oxford in England.
Research by kinesiology investigator Dustin Hittel, PhD, has proven that muscle in extremely obese individuals produces large amounts of a protein called myostatin, which normally inhibits muscle growth?suggesting that for Type 2 diabetics, and the very obese, the task of getting healthy may be more difficult than initially thought.
New research suggests vaccines that specifically target HIV in the initial stages of infection before it becomes a rapidly replicating, system-wide infection - may be a successful approach in limiting the spread of the disease.
Scientists have piggybacked antibodies onto radioactive payloads to deliver doses of radiation that selectively target and destroy microbial and HIV-infected cells
