Model tissue system reveals cellular communication via amino acids
A team of researchers from the Massachusetts General Hospital Center for Engineering in Medicine (MGH-CEM) has found the first evidence of cell-to-cell communication by amino acids, the building blocks of proteins, rather than by known protein signaling agents such as growth factors or cytokines. ...
Genetic evidence for avian influenza movement from Asia to North America via wild birds
Wild migratory birds may be more important carriers of avian influenza viruses from continent to continent than previously thought, according to new scientific research that has important implications for highly pathogenic avian influenza virus surveillance in North America.

Mayo Clinic researchers discover cancer cells may move via wave stimulation
Mayo Clinic researchers have uncovered a new cellular secret that may explain how certain cancers move and spread -- a feature of cancers that makes treatment especially difficult. If the mechanism that drives cancer movement -- also called metastasis -- can be understood well enough to manipulate ...
HIV accessory protein disables host immunity via receptor-protein intermediary
Researchers at the University of Pennsylvania School of Medicine discovered that an HIV-1 accessory protein called Vpr destroys the host cell's ability to survive by binding to a host receptor. This, in turn, keeps an important enzyme from activating the cell's immune system. These findings refine ...
