How do cells establish and maintain their polarity?

The most important and most common channels on cell membrane are voltage-gated Na+ and K+ channels. In so-called "excitable cells" like neurons and muscle ... The cell membrane, regulates what enters and leaves the cell and also provides protection and support. The cell takes in food and water and eliminates wastes. The cell membrane is also known as the plasma membrane. It is the outermost covering of animal cells. It is a semi-permeable membrane composed of lipids and ... We proposed a Protein Layer-Lipid-Protein Island (PLLPI) model, to provide a better understanding of cell membrane structure, membrane trafficking and viral ...
