Cytotoxicity Induced by Fas Ligand/TNFSF6 and Neutralization by Mouse Fas Ligand/TNFSF6 Antibody. In the presence of a cross-linking antibody, Mouse polyHisti-dine Monoclonal Antibody (10 µg/mL, Catalog # MAB050), Recom-binant Mouse Fas Ligand/ TNFSF6 (Catalog # 526-SA) induces cytotoxicity in the Jurkat human acute T cell leukemia cell line in a dose-dependent manner (orange line). Under these conditions, cytotoxicity elicited by Recombinant Mouse Fas Ligand/ TNFSF6 (5 µg/mL) is neutral-ized (green line) by increasing concentrations of Rat Anti-Mouse Fas Ligand/TNFSF6 Monoclonal Antibody (Catalog # MAB5262). The ND50 is typically 5-20 µg/mL.

Detection of Fas Ligand/TNFSF6 by Flow Cytometry CD5+ B cells express higher levels of Fas ligand (FasL) than other splenic populations. Freshly isolated splenocytes from type II collagen/complete Freund's adjuvant (cII/CFA)-immunized, cII T-cell receptor transgenic mice were stained with anti-CD19, anti-CD5, and anti-FasL antibodies as described in Materials and methods. (a) Cells were initially gated as small nongranular lymphocytes by forward scatter and side scatter criteria (not shown) and then categorized by staining with anti-CD19 and anti-CD5 as T cells (CD5hi/CD19-), CD5+ B cells (CD5+/CD19+), B-2 cells (CD5-/CD19+), or double-negatives. (b) Comparison of FasL expression on CD5+ B cells from four mice, with representative disease severity scores shown in parentheses. Numbers in the box are mean fluorescence intensity (MFI) values of FasL staining on CD5+ B cells from the four mice. (c) Histograms and MFI values compared for lymphocyte subsets of two representative mice. (d) Average MFI values of FasL expression on gated splenic lymphocytes from mice with severe (n = 6), moderate (n = 6), and mild or no arthritis (n = 6).

Background: Fas Ligand/TNFSF6
Fas Ligand (FasL) is a 40 kDa type II membrane protein belonging to the TNF family. In the new TNF super family nomenclature, FasL is referred to as TNFSF6. The specific receptor for FasL is Fas (CD95, Apo-1), a 45 kDa type I transmembrane protein that is a member of the TNF receptor family. FasL is predominantly expressed on activated T cells and NK cells, while Fas is expressed on various types of cells. The Fas/FasL system plays a crucial role in modulating immune response by inducing cell apoptosis to maintain homeostasis, self-tolerance of lymphocytes, and immune privilege. FasL was reported to be a potent chemoattractant for neutrophils, suggesting a novel proinflammatory function of this molecule. Like other members of the TNF family, the membrane-bound FasL can be cleaved by metalloproteinase to generate the soluble Fas ligand (sFasL) which is mainly a non-covalently linked homotrimer. It has been shown that the membrane-bound TNF‑ alpha and FasL are primary activators of their receptors. In contrast to soluble TNF‑ alpha which has potent cytotoxicity, sFasL is much less cytotoxic. Studies have shown that sFasL may competitively inhibit the killing effect of membrane FasL indicating that the cleaving of membrane FasL might be a mechanism to down‑regulate their activities.
