Description

Description: The eBio124-1D1 monoclonal antibody reacts with human CD7, also known as gp40 and Leu9. CD7, a 40 kD receptor, is a member of the immunoglobulin gene superfamily. The N-terminal amino acid sequence (aa1-107) is highly homologous to Ig kappa light chain sequence; while the carboxyl-terminal region of the extracellular domain is proline-rich and has been postulated to form a stalk from which the Ig domain projects. CD7 is expressed on the majority of immature and mature T lymphocytes, and T cell leukemias. It is also found on natural killer cells, a small suppopulation of normal B cells and on maligant B cells. Cross-linking surface CD7 positively modulates T cell and NK cell activity, as measured by calcium flux, expression of adhesion molecules, cytokine secretion and proliferation. CD7 associates directly with phosphoinositol 3'-kinase. CD7 ligation induces production of D-3 phosphoinositides and tyrosine phosphorylation. A clonogenic subpopulation of human CD34(+) CD38(-) cord blood cells that express CD45RA and HLA-DR and high levels of the CD7 has been reported. These cells possess the capacity for lymphopoiesis. They can generate B-cells, natural killer cells, and dendritic cells but do not possess the capacity to develop into myeloid cells or erythroid cells. The CD7(+) phenotype distinguishes primitive human lymphoid progenitors from pluripotent stem cells. Furthermore, it has been suggested that CD7 co-operates with CD28 during Treg function, as mice d...

CD7, also known as gp40 or Leu9, is a 40 kDa receptor and member of the immunoglobulin gene superfamily. It features an N-terminal region (amino acids 1-107) that is highly homologous to Ig kappa light chains, while its carboxyl-terminal region is proline-rich, forming a stalk from which the Ig domain projects. CD7 is prominently expressed on the majority of immature and mature T lymphocytes, as well as T cell leukemias. It is also found on natural killer cells, a small subpopulation of normal B cells, and malignant B cells. CD7 plays a crucial role in modulating immune cell activity. Cross-linking of surface CD7 enhances T cell and NK cell functions, as evidenced by increased calcium flux, expression of adhesion molecules, cytokine secretion, and proliferation. CD7 directly associates with phosphoinositol 3-kinase, and its ligation induces the production of D-3 phosphoinositides and tyrosine phosphorylation. The expression of CD7 is an important marker in leukemia diagnostics, highlighting its significance in both normal immune function and disease states.
