Normally, the number of CD56-lymphocytes in the blood in adults is 9-19%.
CD56-lymphocytes are cell-effectors of cellular immunity, responsible for antiviral, antitumor and transplantation immunity (see above CD16-lymphocytes). Reducing the number of CD56-lymphocytes leads to the development of cancer and weighting of the course of viral infections.
