Recombinant Human CD40-Ligand
CD40-Ligand, or CD154, is a membrane glycoprotein and differentiation antigen that is expressed on the surface of T cells, monocytes, basophils, eosinophils, platelets, dendritic cells, and endothelial cells. CD40-Ligand binds and activates the CD40 receptor on antigen-presenting cells. CD40-Ligand stimulates B cell proliferation, immunoglobulin class switching, and antibody secretion. CD40-Ligand also induces cytokine production and tumoricidal activity in peripheral blood monocytes. CD40-Ligand is a co-stimulator of activated T cell proliferation and inflammatory protein production.
