Discovery of T-cell 'traffic control' boosts new drug promise

... trafficking by occupying a receptor on the T cell surface that suppresses the cells' normal response to a "forward march" signal. T cells respond by chemotaxis -- moving from areas of lower to higher concentration of a signaling molecule known as a chemokine. Studies by the two scientists have shown that S...

Quantum dots provide a faster, more sensitive method for detecting respiratory viral infections

...rent "linker" molecules that bind to different RSV surface structures. "It's not much of a jump from two to five," Wright says. Quantum dots are available in a dozen different colors, and antibodies specific to the other four respiratory viruses have been identified and can be used as linker molecules. Such...

In 2003, researchers estimated that more than 300,000 cetaceans are killed in fishing gear each year in the world's oceans. "Rather than simply identifying the species or populati...

Lands surface change on Alaska tundra creating longer, warmer summers in Arctic

Why do aneurysms form? New studies suggest leading role for white blood cells

...researchers looked at L-selectin, a protein on the surface of neutrophils that allow them to attach to tissue. They studied L-selectin production in the aortas of rats that had been injured with elastase or exposed to control conditions.
