'''[[CD1]] (Cluster of Differentiation 1)''' is a family of glycoproteins involved in the presentation of antigens on the surface of specific cells to [https://en.wikipedia.org/wiki/Natural_killer_T_cell NKT cells]. | '''[[CD1]] (Cluster of Differentiation 1)''' is a family of glycoproteins involved in the presentation of antigens on the surface of specific cells to [https://en.wikipedia.org/wiki/Natural_killer_T_cell NKT cells]. CD1 molecules are notably expressed by splenic dendritic cells, marginal zone B cells and CD4+CD8+ thymocytes. The CD1 family is made of three groups. Group 1 is composed of CD1a, b and c proteins and group 2 is composed of CD1d proteins. The third group is the CD1e, which shares some partial characteristics from groups 1 and 2<ref>Jullien, D.; Afanassieff, M.; Claudy, A.; Nicolas, J.; Kaiserlian, D.

Thus, the structure and function of such proteins in mice are akin to those of humans. Mice do not express group 1 CD1 molecules, but they have two kinds of CD1d molecules. Therefore, mice have been widely used to characterize the functions of CD1d and CD1d-dependent NKT cells in many diseases. | Thus, the structure and function of such proteins in mice are akin to those of humans.
