At this point, it is unclear what receptors and cell signaling pathways are involved to get the process started, but from this and previous studies the investigators do report that the signal is from a mechanical stimulus along the length of the axon as opposed to a chemical stimulus. "The stretch is c...

Common cold virus can cause polio in mice when injected into muscles

...different docking sites, called receptors, on host cell surfaces. The current study turned that belief on its head, said Gromeier. Poliomyelitis has long been regarded as the signature of poliovirus, a virus that recognizes and binds to the CD155 receptor. However, the mice were genetically engineered to ...

Mitochondrial genes cause nuclear mischief

While the nucleus of a cell may be its command headquarters, mitochondria are equally vital--they are the power plants of the cell, and without them all cellular activity would quickly and irrevocably come to a halt. Testifying to their origins as once free-living bacteria, mit...
