CD56, also known as a neural cell adhesion molecule (NCAM), is a calcium-independenthomophilic binding protein that belongs to a group of cell adhesion molecules includingcadherins, selectins, and integrins. CD56 is involved in cell-cell adhesion of neural cellsduring embryogenesis and is expressed in most neuroectodermally derived tissues. Innormal tissue, anti-CD56 labels neurons, glia, Schwann cells, NK (natural killer) cells, and asubset of T-cells. CD56 expression can be seen in most NK cell neoplasms,4 and is frequentlyused to identify neoplasms with neuroendocrine differentiation.
