Cell Surface Molecules
Cell surface molecules are proteins and glycoproteins embedded into the cell membrane of all eukaryotic cells. These molecules play an important role in cell-cell recognition, communication and signaling. They have a variety of uses, such as aiding in the recognition between cells, allowing a cell to attach to other cells or surfaces, and mediating cell-cell interactions. These molecules are essential in the normal functioning of the immune system, as they provide a means for cells to recognize foreign substances, and are also important in the regulation of the cell cycle, and in the regulation of the development, differentiation and metabolism of the cell. Cell surface molecules are thus crucial for the functioning of all eukaryotic cells and are of major significance for both medical and research purposes.
