Human immunoglobulins are glycoproteins composed of two disulfide-bonded heavy (H) chain subunits, each of which is linked by interchain disulfide bonds to a light (L) chain forming a tetramolecular complex. There are five classes of immunoglobulins, designated IgG, IgA, IgM, IgD and IgE, which are defined by differences in the constant region of H chains. L chains are divided into kappa or lambda classifications based on structural antigenic differences. All classes of immunoglobulins have been found on the cell surface of B lymphocytes where they function as antigen receptors to elicit antigen-dependent proliferation and secretion of antigen specific soluble circulating antibodies.

Human MHC Class II (HLA-DP, DQ & DR) molecules are expressed on dendritic cells, monocytes, macrophages and myeloid beta cells. MHC Class II molecules are heterodimers of polymorphic transmembrane a and b chains and generally bind exogenously derived peptides of about 10-17 amino acids. MHC Class II molecules interact with the T cell receptor on CD4+ T cells.

Human CD51 is an integrin alpha v chain which can associate with five different integrin beta chains to form various adhesion molecules. The alpha v beta 3 integrin complex binds vitronectin at the RGD sequence and also can bind to fibrinogen, von Willebrand factor, thrombospondin, fibronectin, osteopontin and collagen.

Human CD46 is a cell surface glycoprotein expressed on almost all human cells except erythrocytes. CD46 is involved with regulation of complement activation and is also a measles virus receptor.

Supplier: Adipogen

Human CD45 is expressed on all cells of hematopoietic origin, except erythrocytes. CD45 is a transmembrane tyrosine phosphatase which can exist in at least nine different isoforms resulting from tissue-specific alternative RNA splicing of exons 4-7 of a single gene coding for the various N-terminal peptide segments. The CD45RO isoform contains none of the alternatively spliced exons and is present on most thymocytes, a subpopulation of resting (memory) T cells within both CD4 and CD8 subsets as well as on monocytes and granulocytes. CD45RO plays an essential role in lymphocyte activation.

The inducible costimulator CD278 (ICOS) is similar to human CD28 (24% homology) and plays an analogous role in the T cell activation process. Signaling through CD278 is particularly important in progression of TH2 immune response. The receptor for human CD278 (ICOS) is CD275 (GL50), a member of the B7 family sharing ~20% homology with CD80 (B7-1) and CD86 (B7-2). Blockade of the CD278-CD275 interaction in mice improves allograft survival and reduces EAE.

CD8 identifies cytotoxic/suppressor T cells that interact with MHC Class I bearing targets. CD8 is thought to play a role in the process of T cell mediated killing. CD8-alpha chains binds to Class I MHC molecules alpha-3 domains. Defects in CD8A are a cause of familial CD8 deficiency. Familial CD8 deficiency is a novel autosomal recessive immunologic defect characterized by absence of CD8+ cells, leading to recurrent bacterial infections.

The LTbetaR activates two different NF-kappaB pathways that lead to distinct patterns of gene induction, including selected chemokines and the cytokine BAFF, which is essential for the survival of mature B lymphocytes. LTbetaR activates the classical NF-kappaB (relA/p50) pathway, like the type 1 TNF receptor (TNFR1), that regulates proinflammatory genes, like the chemokine MIP1beta. However, LTbetaR, unlike TNFR1, also activates the processing of p100 to form RelB/p52 complexes, which activate genes involved in lymphoid organ formation and lymphocyte survival.

The inducible costimulator CD278 (ICOS) is similar to human CD28 (24% homology) and plays an analogous role in the T cell activation process. Secondary signaling through CD28 or CD278 results in discrete cytokine secretion profiles by the activated T cells. CD275 (ICOSL; GL50; B7-H2) has been shown to be the ligand for CD278 (ICOS).
