Detection of Mouse OX40 Ligand/TNFSF4 by Flow Cytometry Th2 polarization induced by SEA is mediated via Dectin-2 and Syk signaling in vivo.(A–D) WT or CD11c delta Syk mice were injected with SEA (panel A, B), SEA delta alpha -1/ omega -1 (panel C), or omega -1 (panel D) in the hind footpad, and draining pLNs were analyzed 7 d later. (A, C, D) pLN cells were restimulated with PMA/Ionomycin in the presence of brefeldin A, and CD4+ T cells were stained for indicated intracellular cytokines and percentage cytokine-positive CD4+ T cells enumerated. Based on these data, the ratio between the percentage IL-4+ over IFN-gamma + CD4+ T cells was determined as a measure for overall skewing towards Th2. (B) pLN cells were restimulated with SEA for 72 h, and cytokine levels in culture supernatants were determined. (A–D) Bar graphs represent mean ± SEM of 5 to 6 mice per group and are representative of 2 (panel A–C) or 1 (panel D) experiment. (E) BMDCs cultured from BM from WT, Dectin-1−/−, or Dectin-2−/− mice were pulsed overnight with SEA delta alpha -1/ omega -1 and injected into hind footpads after which CD4+ T-cell responses were analyzed as in panel A. Representative flow cytometry plots of intracellular staining of CD4+ T cells are depicted, of which the data are enumerated in bar graphs representing mean ± SEM of 2 independent experiments with 3 to 6 mice per group. (F) SEA binding and uptake was determined as in Fig 4F. (G) ROS production by indicated BMDCs was determined as described in Fig 5E, 1 h after stimulation with SEA delta alpha -1/ omega -1. Based on MFI, bar graphs represent fold change relative to control condition, which is set to 1. (H) BMDCs were stimulated as indicated for 18 h after which expression of OX40L was analyzed by flow cytometry. Representative plots are depicted, of which the data are enumerated in bar graphs and shown as fold change relative to control condition, which is set to 1, based on percentage positive cells. (F–H) Bar graphs represent mean of duplicates or triplicates ± SEM of 2 independent experiments. “*”: P < 0.05; “**” and “##”: P < 0.01; “***” and “###”: P < 0.001 for significant differences with the control conditions (*) or between-test condition (#) based on unpaired analysis (unpaired Student t test).

Background: OX40 Ligand/TNFSF4

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.
