The virus must recognize special structures on the surface of the cell.
Beneath the fuzz is the brush border on the surface of the cell membrane.
But if PCSK9 does not bind, the receptor can return to the surface of the cell and remove more cholesterol.
It need simply function as an electrical contact and thus covers the entire back surface of the cell structure.
The electrons knocked free at the surface of the cell, however, were not being carried away in this manner.
"Their whole inner workings are different how they shuttle proteins from one spot to another, how they store things, package them, send them to the surface of the cell".
In this system a membrane receptor acts upon an enzyme, phospholipase C, located on the inner surface of the cell membrane.
Labelling is evident on the surface of the cell only.
New HIV proteins are subsequently produced that migrate to the surface of the cell.
These, in turn, shadow the active surface of the cell, compromising the efficiency.
The irradiation power density on the surface of the cell was calibrated to 1000 W/m2.
