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 ...
