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 ...
Neuropilin-1 (NP-1), NRP1 or BDCA-4, has a wide range of functions. On neurons, it is a receptor for axon growth guidance class-3 semaphorins SEMA3A and plexin-1, on endothelial and some tumor cells it is a VEGF 165 receptor, and on plasmacytoid dendritic cells it has a similar role to CD303 but does not decrease interferon production upon ...
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).
CD1D is the human gene that encodes the protein CD1d, [5] a member of the CD1 (cluster of differentiation 1) family of glycoproteins expressed on the surface of various human antigen-presenting cells. They are non-classical MHC proteins, related to the class I MHC proteins, and are involved in the presentation of lipid antigens to T cells. CD1d ...

CD19 is widely expressed during all phases of B cell development until terminal differentiation into plasma cells. During B cell lymphopoiesis, CD19 surface expression starts during immunoglobulin (Ig) gene rearrangement, which coincides during B lineage commitment from hematopoietic stem cell. [8]
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]
PECAM-1 is a highly glycosylated protein with a mass of approximately 130 kDa. [9] The structure of this protein was determined by molecular cloning in 1990, when it was found out that PECAM-1 has an N-terminal domain with 574 amino acids, a transmembrane domain with 19 amino acids and a C-terminal cytoplasmic domain with 118 amino acids.
