背景 | OX40 Ligand (OX40L), also known as gp34, is a type II transmembrane glycoprotein designated TNFSF4 within the TNF superfamily. Human OX40L cDNA encodes a 183 amino acids (aa) polypeptide with an amino-terminal cytoplasmic domain (aa 1-23) and a carboxy-terminal extracellular domain (aa 51-183). It shares 46% aa sequence identity with the mouse counterpart. OX40L is expressed on the surface of activated B cells, T cells, dendritic cells and endothelial cells. Like other TNF superfamily members, membrane-bound OX40 Ligand exists as a homotrimer. OX40L binds to OX40 (CD134), a member of the TNF receptor superfamily that is expressed predominantly on activated CD4+ T cells. OX40 Ligand is one of the group of co-stimulatory molecules in the immune system that includes B7, CD40 Ligand, CD30 Ligand, CD27 Ligand and 4-1BB Ligand. OX40 appears as a late activation-induced T cell surface antigen, and its major function of OX40-OX40L interaction may be to transmit a late co-stimulatory signal to promote the survival and proliferation of activated CD4+ T cells and prolong the immune response. Engagement of OX40 on activated T cells in situ in tumors has been shown to augment immune responses and subsequent tumor regression. |

Detection of OX40 Ligand/ TNFSF4 in Human Mature Dendritic Cells by Flow Cytometry. Human mature dentritic cells differentated from human peripheral blood mononuclear cell derived CD14+ cells treated with 20 ng/mL Recombinant Human IL‑4 (Catalog # 204-IL) and 50 ng/mL Recombinant Human GM‑CSF (Catalog # 215-GM) for 7 days and 1 μg/mL LPS, 20 ng/mL Recombinant Human TNF‑ alpha (Catalog # 210-TA), and 20 ng/mL Recombinant Human IL‑1 beta /IL‑1F2 (Catalog # 201-LB) for last 24 hours were stained with Mouse Anti-Human OX40 Ligand/TNFSF4 Monoclonal Antibody(Catalog # MAB10541, filled histogram) or isotype control (Catalog # MAB002, open histogram), followed by Goat F(ab)2 Anti-Mouse IgG (H+L) Allophycocyanin (Catalog # F0101B). | |

IL‑8 Secretion Induced by OX40 Ligand/TNFSF4 and Neutralization by Human OX40 Ligand/TNFSF4 Antibody. Recombinant Human OX40 Ligand/TNFSF4 (Catalog # 1054-OX) induces IL‑8 secretion in the HT1080 human fibrosarcoma cell line transfected with human OX40 in a dose-dependent manner (orange line) as measured by Human IL‑8 Duoset (Catalog # DY208). IL‑8 Secretion elicited by Recombinant Human OX40 Ligand/TNFSF4 (10 ng/mL) is neutralized (green line) by increasing concentrations of Mouse Anti-Human OX40 Ligand/TNFSF4 Monoclonal Antibody (Catalog # MAB10541). The ND50 is typically 0.1-0.6 μg/mL. |
