CD40L (CD40 ligand), also known as TNFSF5 and CD154, is a cytokine that belongs to the tumor necrosis factor (TNF) superfamily (TNFSF). CD40L/CD154 is a single-pass type II transmebrane glycoprotein consisting of a 22 amino acid (aa) cytoplasmic domain, a 24-aa transmembrane domain (TM) and a 215 aa extracellular domain (ECD). CD40L is expressed on the surface of T cells. It regulates B cell function by engaging CD40 on the B cell surface. CD40L co-stimulates T-cell proliferation and cytokine production. Its cross-linking on T-cells generates a costimulatory signal which enhances the production of IL4 and IL10 in conjunction with the TCR/CD3 ligation and CD28 costimulation. A defect in the CD40L gene results in an inability to undergo immunoglobulin class switch and is associated with hyper-IgM syndrome.
