Enzyme's newly discovered role may make it target for arthritis treatment

... surface of neutrophils. "The way these integrins rearrange and cluster on the cell surface can send a signal back into the cell that modifies the cell's behavior, allowing it to do things like secrete inflammatory factors," Pham explains. "The proteases' ability to affect integrin rearrangement is dependent ...

Researchers discover how bacteria sense their environments

...some sort triggers an array of linked receptors to rearrange itself, much like when water freezes, all the water molecules assort themselves into a new structure. Through this reorganization, the bacterium's receptor array amplifies the signal that a specific molecule has been sensed outside the cell. This str...

MIT device draws cells close -- but not too close -- together

...ming, it is important for biologists to be able to rearrange cells over time to learn which signals spur change and which don't. In the past, researchers erected chemical "moats" around cells in an attempt to keep them close but separate. Over time, however, cells invariably breech the divide. "They are ve...

Scientists identify specific enzymes that make meningitis hard to fight

...et of meningitis' virulence lies in its ability to rearrange its DNA and thus change its external appearance to the body's immune system. Significantly our research has now demonstrated that the ability of meningitis to repair its DNA is important for its ability to survive attack from the body's immune system...
