  • Overview of CD40LG molecular targets


    CD40 ligand (CD40L/CD154) is a member of the TNF superfamily of molecules. It is a 39 kDa glycoprotein that is primarily expressed on activated T cells. Soluble CD40L (sCD40L) with a molecular weight of 15-18 kDa is produced by proteolysis. CD40L binds to CD40 on the surface of antigen presenting cells (APCs) and can have a variety of effects depending on the target cell type. CD40L is particularly important as a co-stimulatory molecule for the T cell subset follicular helper T cells (Tfh cells). In Tfh cells, CD40L binds to CD40 on the surface of B cells, promoting B cell maturation and function, thereby promoting cell-to-cell communication. Loss of the CD40L gene results in the inability to switch immunoglobulin classes and is associated with hyper-IgM syndrome. Loss of CD40L also blocks germinal center formation, thereby preventing antibody affinity maturation, an important process in the adaptive immune system.
