Exhausted B Cells Fail To Fight HIV

Antibodies stick to HIV particles, preventing them from infecting other cells and triggering their destruction by immune cells. This antibody response starts out strong in HIV-infected individuals but eventually peters out. To find out why, scientists from the National Institute of Allergy and Infectious Diseases examined the cells that make the antibodies, known as B cells. The group now finds that HIV gradually depletes the numbers of healthy, functional B cells.

Exhausted B Cells Hamper Immune Response To HIV
15.07.2008 09:13

WHAT: Recent studies have shown that HIV causes a vigorous and prolonged immune response that eventually leads to the exhaustion of key immune system cells--CD4+ and CD8+ T-cells--that target HIV. These tired cells become less and less able to fight the virus, and the cells' fatigue contributes to the inability of an HIV-infected person's immune system to clear the virus from the body.

Test For Heart Failure Can Detect More Than Blockages

A less invasive test commonly used to diagnose coronary disease also may be used to detect one of the leading causes of heart failure, say researchers at the Medical College of Georgia. By using a nuclear stress test to look at how fast blood flows into the heart's pumping chamber - the left ventricle - they can determine if a patient's left ventricle is having trouble.

Scientists of the Division of Theoretical Bioinformatics at the German Cancer Research Center (Deutsches Krebsforschungszentrum, DKFZ) in Heidelberg have simulated on the computer how cells decide whether or not to migrate. Using their results, the researchers were able to predict the molecular targets within a cell that have to be hit so that its behavior changes in a particular direction. This method may help to develop new treatments against cancer metastasis.

In an Australian first, scientists at Sydney's Centenary Institute have mapped the anatomy of a membrane protein. This exciting discovery has the potential to turn the way we discover new drugs on its head and reduce the development time for new treatments. "These membrane proteins are the target for 70% of all therapeutic drugs so an increased understanding of them is vital for future drug discoveries," said Centenary Institute Executive Director, Professor Mathew Vadas.

Increased Risk Of Kidney Stone Disease Due To Global Warming, Predicts UT Southwestern Researchers

Global warming is likely to increase the proportion of the population affected by kidney stones by expanding the higher-risk region known as the "kidney-stone belt" into neighboring states, researchers at UT Southwestern Medical Center and UT Dallas have found. Dehydration is one of the risk factors linked to kidney-stone disease, and the paper suggests global warming will exacerbate this effect. The researchers predict that by 2050, higher temperatures will cause an additional 1.
