                                      List and summary of all human CD antigens from CD1a to CD371.

                                      Updated August 5, 2021

                                      The cluster of differentiation (CD) is a nomenclature system conceived to identify and classify antigens found on the cell surface of leukocytes. Initially, surface antigens were named after the monoclonal antibodies that bound to them. As there were often multiple monoclonal antibodies raised against each antigen in different labs, the need arose to adopt a consistent nomenclature. The current system was adopted in 1982 through the 1st International Workshop and Conference on Human Leukocyte Differentiation Antigens (HLDA). The Human Cell Differentiation Molecules organization continues to hold HLDA conferences to maintain and develop the list of known CD markers. 

                                      Under this naming system, antigens that are well characterized are assigned an arbitrary number (eg CD1, CD2 etc) whereas molecules that are recognized by just one monoclonal antibody are given the provisional designation “CDw” eg CDw50. Lower class letters are also added after the assigned number to indicate larger molecules that share a common chain, for example CD1a or CD1d.  Physiologically, CD molecules do not belong in any particular class, with their functions ranging widely from cell surface receptors to adhesion molecules. Although initially used just for human leukocytes, the CD molecule naming convention has now been expanded to cover different species (eg mouse) as well as other cell types. As of April 2016, human CD antigens are numbered up to CD371.

                                      The presence or absence of a specific antigen from the surface of a particular cell population is denoted with “+” or “-" respectively. Varying cellular expression levels are also marked as hi or low, for example central memory T-cells are CD62Lhi whereas effector memory T-cells are CD62Llow. Monitoring the expression profiles of different CD antigens has permitted the identification, isolation and phenotyping of cell types according to their function in various immune processes.
