Protein controls acid in cells by direct detection of volume changes, study finds
...re the blood supply is cut off to cardiac cells or brain
cells, cells become very acidic. As the body's normal metabolism gets going again, the NHE1 system starts pumping out the accumulated acid, exchanging the acid for sodium. "It's such an active system that you can overload the cell with sodium," Dr. H...
