There's Life After Radiation for Brain Cells. Johns Hopkins researchers suggest neural stem cells may regenerate after anti-cancer treatment. Release Date: August 12, 2013. Scientists have long believed that healthy brain cells, once damaged by radiation designed to kill brain tumors, cannot regenerate.
The key player in acid secretion is a H+/K+ ATPase or proton pump located in the cannalicular membrane. 1  This ATPase is magnesium-dependent, and not inhibitable by ouabain. The current model for explaining acid secretion is as follows: 2  Hydrogen ions are generated within the parietal cell from dissociation of water.
And while proton pump inhibitors are designed to interact specifically with the hydrogen/potassium pump in parietal cells of the stomach, research suggests that they likely have nonspecific binding capabilities (3). In other words, their chemical structure enables them to bind to other proton pumps as well.
