Description: The human sCD40L ELISA is an enzyme-linked immunosorbent assay for the quantitative detection of human sCD40L. The human sCD40L ELISA is for research use only. Not for diagnostic or therapeutic procedures.
CD40 belongs to the TNF receptor superfamily and is a biochemical marker for the identification of activated platelets of patients with cardiovascular diseases (angina pectoris, infarction, stroke etc.)
A key role of CD40/CD40ligand interactions in immune activation, particularly in T-cell dependent B cell responses is anticipated. CD40 Ligand is expressed on the surface of activated CD4+ T cells, basophils, and mast cells. Binding of CD40L to its receptor, CD40, on the surface of B cells stimulates B-cell proliferation, adhesion and differentiation. A soluble isoform of CD40L has been shown to exist in the circulation. This soluble molecule is a homotrimer of a 18kDa protein exhibiting full activity in B cell proliferation and differentiation assays, is able to rescue B cells from apoptosis and binds soluble CD40.
CD40L is discussed in relation to a potential role in supporting B cell tumors and it has been discovered that the molecular defect in the X-linked Hyper-IgM-Syndrome is targeted to the CD40 L gene, it is functional involved in B cell hybridomas and chronic lymphocytic leukemia as well as several autoimmune diseases.
