CD40L (CD154; TRAP) is a ligand to CD40/TNFRSF5, acts function by generating a costimulatory signal that up-regulates IL-4 synthesis [1] . CD40L is specifically expressed on activated CD4+ T-lymphocytes and involves in activation of NF-κB/MAPK pathway [2] [3] . CD40L also involves in B cell differentiation, maturation, and apoptosis [4] . CD40L in mouse, cleaved into 2 chains of membrane form (1-260 a.a.) and soluble form (112-260 a.a.) which serves as a ligand for integrins (ITGA5:ITGB1 and ITGAV:ITGB3). CD40L/CD154/TRAP Trimer Protein, Mouse (HEK293, Fc) has a total length of 149 amino acids (M112-L260), is expressed in HEK392 cells with N-terminal hFc-tag.

Mouse

CD40 Ligand (CD40L; CD154; TRAP) belongs to the tumor necrosis factor (TNF) family, is the ligand for CD40/TNFRSF5, specifically expressed on activated CD4+ T-lymphocytes [1] . CD40L is a type II transmembrane protein on B cells triggers important signals for B cell differentiation, maturation, and apoptosis [4] . CD40L acts function by cross-linking on T-cells to generate a costimulatory signal and thus enhances the production of IL4 and IL10 in conjunction with the TCR/CD3 ligation and CD28 costimulation, as well as promoting the production of interferon-γ, and TNF-α [1] [4] . CD40L, binding with CD40 on antigen-presenting cells (APC), activates TNFR-associated factor 2- and IKK2-dependent pathways with stimulating I-κB kinase (IKK), increasing NF-κB DNA binding, and p65 nuclear translocation. The activation of I-κB kinase leads to strongly c-Jun N-terminal kinase activation as well as GST-I-κB and GST-p65 phosphorylation [2] . CD40L involves in MAPK pathways that strongly repress Bcl-6 with inducing the phosphorylation of Erk1/2, p38 and Jnk1/2 and activating IRF4 mediated by NF-κB [3] . CD40L also binds to and signals through several integrins, including αvβ3 and α5β1, which bind to the trimeric interface of CD40L. CD40L plays a major role in immune response and is a major target for inflammation [5] . CD40L is widely found in different animals, while the sequence in Mouse is highly similar to Rat (93.85%), but very different from Human and Rhesus macaque with similarities of 77.69% and 77.31%, respectively. CD40L in Mouse is cleaved into 2 chains of membrane form (1-260 a.a.) and soluble form (112-260 a.a.), while the soluble form in human derives from the membrane form by proteolytic processing. Release of soluble CD40L from platelets is partially regulated by GP IIb/IIIa, actin polymerization, and a matrix metalloproteinases (MMP) inhibitor-sensitive pathway [6] .
