Researchers discover 'reservoir' that allows HIV to remain infectious despite treatment

Researchers at Brigham Young University and the Johns Hopkins School of Medicine have discovered a human cell "reservoir," called follicular dendritic cells, that allows HIV to stay in an infectious state and not respond to antiretroviral drugs, the Deseret Morning News reports.

Effectiveness of antiretroviral therapy causing 'complacency' among high-risk groups

HIV/AIDS clinicians and scientists have been "witness to a transformation in disease management that is virtually unprecedented in the history of medicine," Mark Wainberg, director of McGill University's AIDS Centre at Jewish General Hospital, and Julio Montaner, director of the BC Centre for Excellence in HIV/AIDS, write in a National Post opinion piece.

Men at increased risk of death from pneumonia compared to women

Men who come to the hospital with pneumonia generally are sicker than women and have a higher risk of dying over the next year, despite aggressive medical care, according to a study being presented Tuesday, May 20, at the 104th International Conference of the American Thoracic Society. Scientific sessions are scheduled May 16 to 21 in Toronto.

Personalized therapy for asthma and chronic obstructive pulmonary disease could soon be here

Researchers at Washington University School of Medicine in St. Louis have defined a new type of immune response that is activated in patients with severe asthma and COPD (chronic obstructive pulmonary disease). Their discovery could dramatically improve diagnosis and treatment of patients with chronic inflammatory lung disease.

DNA vaccines boosted by dendritic cells

The concept sounds ideal: vaccines made of DNA that could be taken in by other cells and give instructions for how to fight off different diseases. The reality, however, has fallen short. Although DNA vaccines have been around for about 15 years and shown lots of promise for HIV, SARS and influenza vaccines during preclinical testing in mice, researchers have yet to make them potent enough to be helpful in humans.

Length of telomeres in blood cells tied to breast cancer survival rates

Researchers at Umea University in Sweden have shown that the length of telomeres in blood cells in newly diagnosed breast cancer patients is tied to survival rates. The study, published in the journal Cancer Research, was carried out by a research team headed by Professor Goran Roos at the Department of Medical Bioscience, Pathology.

China struggles to cope with killer virus amid earthquake devastation

The death toll in China from hand-foot-mouth disease has now risen to 42 with another 24,934 children sickened by the deadly virus; all the fatalities have been children.

First evidence of native dendritic cells in brain

In a finding that has the potential to change the way researchers think about the brain, scientists at Rockefeller University have found dendritic cells where they've never been seen before: among this organ's neurons and connective cells.

Increased research, determination needed in HIV/AIDS vaccine efforts, HIV vaccine enterprise head says

The disappointment that followed the cancellation of a Merck vaccine trial in September 2007 has been replaced by a renewed determination among the scientific community, Alan Bernstein, executive director of the Global HIV Vaccine Enterprise, said ahead of the 25th anniversary of the scientific paper announcing the discovery of HIV, the CP/Yahoo! News reports.

Breastfeeding may protect women from rheumatoid arthritis

Swedish researchers have found in a study on rheumatoid arthritis that breastfeeding protects women from the disease.

Study shows how T cell's machinery dials down autoimmunity

A St. Jude Children's Research Hospital study shows that T cells, the body's master immune regulators, do not use simple on/off switches to govern the cellular machinery that regulates their development and function. Rather, they possess sophisticated molecular controls that enable them to adjust their function with exquisite precision. Such subtle adjustment enables T cells to modulate their development and function, including avoiding autoimmunity

Kenya launches campaign to increase tuberculosis screening among HIV-positive people

The Kenyan government on Tuesday launched a 60 million shilling -- or about $975,000 -- campaign to increase the number of HIV-positive people who are screened for tuberculosis at public hospitals, Kenya's Nation reports. The campaign also aims to educate health workers to test people with TB for HIV.

New theory suggests how hepatitis C may cause rare immune disease

Of the hepatitis alphabet, the C variant may be the nastiest. In 1990, researchers observed that most patients with hepatitis C also develop a rare autoimmune disease called mixed cryoglobulinemia, a condition that frequently leads to cancer, arthritis or both.
