Description: CD69, also known as very early activation (VEA) antigen, is a disulfide-linked transmembrane homodimer whose differentially glycosylated subunits range from 35-39 kDa. It is a C-type lectin most closely related to the NKR-P1 and Ly-49 NK cell-activation molecules. CD69 is widely expressed on hematopoietic cells, including lymphocytes, neutrophils and eosinophils. Although not detectable on resting lymphocytes, its expression is rapidly upregulated upon activation of T, B and NK cells, and neutrophils. Constitutive expression of CD69 on subsets of thymocytes suggests that it may be involved in regulation of developmental events in addition to its role in activation of a variety of hematopoietic cells. The monoclonal antibody H1.2F3 augments PMA-induced T-cell proliferation and induces redirected lysis of Fc receptor-bearing target cells by NK cells.

Description: CD45, also known as the leukocyte common antigen (LCA), exists as four different isoforms (180, 190, 205, 220 kDa) that are generated by alternative splicing of three exons. LCA is found on all cells of hematopoietic origin, except erythrocytes and platelets. CD45 expression is required for T cell and B cell antigen receptor-mediated activation.

Description: CD86, also known as B7-2, is a type I transmembrane glycoprotein and a member of the immunoglobulin superfamily of cell surface receptors. It is expressed at high levels on resting peripheral monocytes and dendritic cells and at very low density on resting B and T lymphocytes. CD86 expression is rapidly upregulated by B-cell specific stimuli with peak expression at 18-42 hours after stimulation. CD86, along with CD80 (B7-1), is an important accessory molecule in T cell costimulation via its interaction with CD28 and CD152 (CTLA-4). Since CD86 has rapid kinetics of induction, it is believed to be the major CD28 ligand expressed early in the immune response. The monoclonal antibody GL1 blocks mixed lymphocyte reactions and stimulation of T cells by antigen-presenting cells.

Description: CD19 is a type I transmembrane glycoprotein and a member of the immunoglobulin superfamily. It is expressed at all stages of B cell differentiation except terminally differentiated plasma cells. It is also present on the cell surface of follicular dendritic cells. CD19 associates with CD21, CD81, Leu 13 and/or MHC Class II molecules to form a signal transduction complex on the B cell surface. This signaling complex modulates the activation threshold for the B cell antigen receptor (BCR).

Description: CD31, also known as platelet endothelial cell adhesion molecule-1 (PECAM-1), is a type I integral membrane glycoprotein and a member of the immunoglobulin superfamily of cell surface receptors. It is constitutively expressed on the surface of endothelial cells and concentrated at the junction between them. It is also weakly expressed on many peripheral lymphoid cells and platelets. CD31 interacts homotypically in cell adhesion assays. The monoclonal antibody 390 inhibits the aggregation of L cells transfected with a variant form of CD31.

Description: The 3C4 monoclonal antibody reacts with the cell surface glycoprotein mouse CD102 (ICAM-2), a ligand for the leucocyte integrin CD11a/CD18 (LFA-1). CD102 is constitutively expressed on T cells, B cells, and at high levels on vascular endothelial cells. It is also expressed on a variety of leukocyte cell lines. The 3C4 antibody blocks the interaction between ICAM-2 and LFA-1.

Description: CD106, also known as VCAM-1, is an adhesion molecule and a major mediator of the inflammatory response. It is expressed on activated microvascular endothelial cells in response to signals arising from immune responses in infection, graft rejection, tumor recognition and killing. The complementary binding ligand for VCAM-1 is VLA-4/CD49d. In addition to VCAM-1, VLA-4 also recognizes the extracellular matrix molecule fibronectin. This pairing of VCAM-1 and VLA-4 is able to provide a second signal (e.g., non-antigen specific) for T cell stimulation, such as that seen in transplantation. The monoclonal antibody MK-2 has been used in transplant studies to suppress cardiac rejection and induce long-term cardiac graft survival. In addition to inflammatory responses, VCAM-1 has a significant role in hemopoiesis through its ability to retain lymphocyte and myeloid precursors on stromal cells in the marrow and lymphoid organs. CD106/VCAM-1 exists as an integral membrane protein. The M/K-2 monoclonal antibody immunoprecipitates a peptide that gives a single band on SDS-PAGE gels with an apparent Mr of ~100 kDa under reducing conditions and 92 kDa under non-reducing conditions.
