The CD nomenclature was proposed and established in the 1st International Workshop and Conference on Human Leukocyte Differentiation Antigens (HLDA), held in Paris in 1982. [4] [5] This system was intended for the classification of the many monoclonal antibodies (mAbs) generated by different laboratories around the world against epitopes on the surface molecules of leukocytes (white blood cells).
CD96 is a transmembrane glycoprotein that has three extracellular immunoglobulin-like domains and is expressed by all resting human and mouse NK cells. CD96 main ligand is CD155. CD 96 has approximately 20% homology with CD226 and competed for binding to CD155 with CD226. CD97: CD97 antigen encoded by the CD97 gene.

CD4 interacts with the β 2-domain of MHC class II molecules through its D 1 domain. T cells displaying CD4 molecules (and not CD8) on their surface, therefore, are specific for antigens presented by MHC II and not by MHC class I (they are MHC class II-restricted). MHC class I contains Beta-2 microglobulin. [citation needed]
CD1 (cluster of differentiation 1) is a family of glycoproteins expressed on the surface of various human antigen-presenting cells.CD1 glycoproteins are structurally related to the class I MHC molecules, however, in contrast to MHC class 1 proteins, they present lipids, glycolipids and small molecules antigens, from both endogenous and pathogenic proteins, to T cells and activate an immune ...
α-galactosylceramide (α-GalCer), a compound originally derived from the marine sponge Agelas mauritanius [6] with no physiological role but great research utility. α- glucuronyl- and α- galacturonyl- ceramides , a family of compounds of microbial origin which can be found, for example, on the cell wall of Sphingomonas , a ubiquitous Gram ...
These are not the only molecules that can transverse the blood–brain barrier; glucose, oxygen and carbon dioxide are not lipid-soluble but are actively transported across the barrier, to support the normal cellular function of the brain. [3] The fact that molecules have to fully transverse the endothelial cells makes them a perfect barricade ...
CD47 (Cluster of Differentiation 47) also known as integrin associated protein (IAP) is a transmembrane protein that in humans is encoded by the CD47 gene.CD47 belongs to the immunoglobulin superfamily [5] and partners with membrane integrins and also binds the ligands thrombospondin 1 (TSP-1) and signal-regulatory protein alpha (SIRPα).
