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 ...
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).
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 ...
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 ...

PECAM-1 contributes to at least two of the nervous system diseases, multiple sclerosis and cerebral ischaemia. First signs of multiple sclerosis are defects in the blood brain barrier and leukocyte migration mediated by adhesion molecules such as PECAM-1. Moreover, monocytes in patients with multiple sclerosis express high level of PECAM-1.
CD163 (Cluster of Differentiation 163) is a protein that in humans is encoded by the CD163 gene. [5] CD163 is the high affinity scavenger receptor for the hemoglobin-haptoglobin complex [6] and in the absence of haptoglobin - with lower affinity - for hemoglobin alone. [7]
Neural cell adhesion molecule (NCAM), also called CD56, is a homophilic binding glycoprotein expressed on the surface of neurons, glia and skeletal muscle.Although CD56 is often considered a marker of neural lineage commitment due to its discovery site, CD56 expression is also found in, among others, the hematopoietic system.
