CD22 functions as an inhibitory receptor for B cell receptor (BCR) signalling. Like CD19, CD22 is a cell surface marker for lymphocytes that is present on most B cell malignancies, including acute lymphoblastic leukemia and various subtypes of non-Hodgkin lymphoma, including diffuse large B-cell lymphoma. CD22 expression has been shown to be ...
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).
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.
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 ...
VCAM-1 is a member of the immunoglobulin superfamily, the superfamily of proteins including antibodies and T-cell receptors.The VCAM-1 gene contains six or seven immunoglobulin domains, and is expressed on both large and small blood vessels only after the endothelial cells are stimulated by cytokines.
[35] [36] In brain tissue, CD97 is undetectable in normal white matter, and expression of CD55 is fairly restricted to the endothelium. In pre-active lesion, increased expression of CD55 in endothelial cells and robust CD97 expression on infiltrating leukocytes suggest a possible role of both molecules in immune cell migration through the blood ...
CD1d is the only member of the group 2 CD1 molecules. Biological significance ... In obesity, NKT cells exhibit both an inflammatory and anti-inflammatory function.
HLA class II histocompatibility antigen gamma chain also known as HLA-DR antigens-associated invariant chain or CD74 (Cluster of Differentiation 74), is a protein that in humans is encoded by the CD74 gene.
