The CD system is commonly used as cell markers, allowing cells to be defined based on what molecules are present on their surface. These markers are often used to associate cells with certain immune functions. CD molecules can act in numerous ways, often acting as receptors or ligands (the molecule that activates a receptor) important to the cell. A signal cascade is usually initiated, altering the behavior of the cell (see cell signaling). Some CD proteins do not play a role in cell signaling, but have other functions, such as cell adhesion.
