Gene for immune deficiency syndromes found

...I binds to two other proteins made by cells in the respiratory and gastrointestinal lining, known as APRIL and BAFF, to trigger the signal for B cells to mature. Geha believes that additional cases of immune deficiency result from mutations in the APRIL and BAFF genes, and plans to verify this in further studies...

Sensor web simulation investigates technique to improve prediction of pollution across the globe

For asthmatics and for anyone with respiratory problems, air pollution can significantly impair simple everyday activities. NASA is trying to tie together satellites and stations on the ground to develop a "sensor web" to track this pollution and improve air quality forecasts. Understanding how ...

New study shows SARS can infect brain tissue

Severe acute respiratory syndrome (SARS), by its very name, indicates a disease of the respiratory tract. But SARS can also infiltrate brain tissue, causing significant central nervous system problem...

UCLA scientists reveal how Nipah virus infects cells

... virus to people, where it causes life-threatening respiratory and neurological diseases that kill up to 70 percent of patients ?a danger level equivalent to the Ebola virus. To infect a cell, viruses must bind to a viral-specific receptor on the cell's surface in order to penetrate it. Lee's team identified a ...
