Potassium, magnesium and membranes. Review of present status and new findings

Magnesium
M Bara, A Guiet-Bara

Abstract

The interactions between magnesium, potassium and various membranes were examined. The different membranes chosen were: artificial, erythrocyte, cardiac, muscular, nervous, gallbladder, urinary bladder, mitochondrial and human amniotic. In general, Mg++ and K+ act on the cellular adhesion and on the stability of the membrane by forming bonds between the charges of the lipids and the proteins. Mg++ acts on the passive K+ transfer either by activation or inhibition. In addition, Mg++ acts on the K+ active transfer: the presence of Mg++ is essential to maintain the activity of the membrane (Na+K) adenosine triphosphatase (ATPase).

Adhesion Molecules in Health and Disease

Cell adhesion molecules are a subset of cell adhesion proteins located on the cell surface involved in binding with other cells or with the extracellular matrix in the process called cell adhesion. In essence, cell adhesion molecules help cells stick to each other and to their surroundings. Cell adhesion is a crucial component in maintaining tissue structure and function.
