Details

CD40 Ligand (CD40L), also known as CD154, TRAP, or gp39, is a type II transmembrane glycoprotein belonging to the tumor necrosis factor (TNF) family. It is mainly expressed in CD4+-T cells and interacts with CD40 on antigen-presenting cells to regulate both humoral and cellular immune responses [1-3].

The CD40 cytoplasmic domain binds directly to several TNF receptor-associated factors (TRAFs), and this interaction is thought to initiate CD40 signaling. CD40-mediated signaling results in NF-κB, c-Jun N-terminal kinase (JNK), and p38 mitogen-activated protein kinase (MAPK) activation. CD40L-CD40 interactions are thought to play an important role in the pathogenesis of many diseases [4, 5].
