CD antigens are proteins originally defined as being present on the cell surface of leucocytes but now including some intracellular molecules and molecules present on cells other than leucocytes. Such molecules are assigned a CD number following a consensus reached at regularly held international workshops. CD antigens include a large number of cell surface receptors, signalling molecules and adhesion molecules.
