New study sheds light on higher adherence to HIV drugs in Africa than in North America

Levels of near-perfect adherence to life saving antiretroviral drugs among African HIV patients should be understood as a means of preserving key social relationships, says a new study published in the open-access journal PLoS Medicine.

Waging war on tropical diseases may be key to U.S. foreign policy

Stating that neglected tropical diseases (NTDs) not only promote poverty but also destabilize communities, former Health and Human Services Secretary Tommy Thompson and Sabin Vaccine Institute President Peter Hotez call upon the public-health and foreign-policy communities to embrace medical diplomacy and NTD control as a means to combat terrorism in an article published January 27 in the open-access journal PLoS Neglected Tropical Diseases.

STDs disrupt genetic bottleneck that usually constrains HIV infection

Scientists have shown that HIV faces a genetic "bottleneck" when the virus is transmitted heterosexually from one person to another, by way of the genital mucosa.

Topical treatment wipes out herpes with RNAi

Whether condoms or abstinence, most efforts to prevent sexually transmitted diseases have a common logic: keep the pathogen out of your body altogether.

Potential new target in the war on HIV/AIDS

The study revealed that a variant of a protein involved in HIV pathogenesis can suppress production of an HIV protein, known as Nef. Nef is required for the human immunodeficiency virus to develop into AIDS through a series of complex events involving viral elements and cellular proteins. Nef has never been a target for drug treatment in HIV patients.

Topical microbicide protects against genital herpes

A topical microbicide that silences two genes can safely protect against genital herpes infection for as long as one week, according to a joint study by researchers at the Albert Einstein College of Medicine of Yeshiva University and Harvard Medical School.

Too much weight loss can be a bad thing

Doctors are not doing enough to pick up on problems with excessive weight loss, says a Saint Louis University physician who helped draft recent guidelines to diagnose the condition called "cachexia" (kuh-kex-ee-uh).

Kidney transplant survival can be long-term for people with HIV

A Johns Hopkins study finds that HIV-positive kidney transplant recipients could have the same one-year survival rates for themselves and their donor organs as those without HIV, provided certain risk factors for transplant failure are recognized and tightly managed.

Mutant host cell protein sequesters critical HIV-1 element

Scientists have identified a new way to inhibit a molecule that is critical for HIV pathogenesis.

Blood type - new weapon in battle against HIV infection

Researchers have discovered a potentially important new resistance factor in the battle against HIV: blood types.

Discovery of new regulatory circuit controlling immune cell production in mice

Using a mouse model, researchers have shown that elevated levels of a small protein known as interleukin 7 (IL-7) plays a central role in regulating the production of a type of white blood cell that is required for effective immune responses.

New hope for transplant recipients and AIDS patients

A researcher from the Université de Montréal and the Maisonneuve-Rosemont Hospital has discovered the mechanism that prevents the regeneration of CD4+ T lymphocytes, which are white cells that are required for the proper functioning of the immune system.

Experts warn Australia is surrounded by a ring of disease hot-spots

Australian biosecurity experts have warned that Australia is surrounded to its north by a 'ring of fire' where new human and animal plagues could appear with very little warning and with potentially dire consequences.

Prolonged nevirapine in breast-fed babies prevents HIV infection but leads to drug-resistant HIV

Babies born to HIV-positive mothers and given the antiretroviral drug nevirapine through the first six weeks of life to prevent infection via breast-feeding are at high risk for developing drug-resistant HIV if they get infected anyway, a team of researchers report.
