Cell Proliferation Induced by IL‑15 and Neutralization by Human IL‑15 Antibody.

Cell Proliferation Induced by IL‑15 and Neutralization by Human IL‑15 Antibody.

Recombinant Human IL-15 (Catalog # 247-ILB) stimulates proliferation in the MO7e human megakaryocytic leukemic cell line in a dose-dependent manner (orange line), as measured by Resazurin (Catalog # AR002). Proliferation elicited by Recombinant Human IL-15 (5 ng/mL) is neutralized (green line) by increasing concentrations of Mouse Anti-Human IL-15 Monoclonal Antibody (Catalog # MAB2471). The ND50 is typically 0.1-0.5 µg/mL.

Detection of IL‑15 in Human peripheral blood mononuclear cells (PBMCs) treated with 1µg/mL LPS for 16 hrs by Flow Cytometry

Human peripheral blood mononuclear cells (PBMCs) treated with 1µg/mL LPS for 16 hrs were stained with Mouse Anti-Human IL‑15 Monoclonal Antibody (Catalog # MAB2471, filled histogram) or isotype control antibody (Catalog # MAB002, open histogram) followed by Fluorescein-conjugated Anti-Mouse IgG Secondary Antibody (Catalog # F0103B). To facilitate intracellular staining, cells were fixed with Flow Cytometry Fixation Buffer (Catalog # FC004) and permeabilized with Flow Cytometry Permeabilization/Wash Buffer I (Catalog # FC005).

Background: IL-15

Interleukin 15 (IL-15) is a widely expressed 14 kDa cytokine that is structurally and functionally related to IL-2 (1‑3). Mature human IL‑15 shares 70% amino acid sequence identity with mouse and rat IL-15. Alternate splicing generates isoforms of IL-15 with either a long or short signal peptide (LSP or SSP), and the SSP isoform is retained intracellularly (4). IL-15 binds with high affinity to IL-15 R alpha (5). It binds with lower affinity to a complex of IL-2 R beta and the common gamma chain ( gamma c) which are also subunits of the IL-2 receptor complex (1, 6). IL-15 associates with IL-15 R alpha in the endoplasmic reticulum, and this complex is expressed on the cell surface (7, 8). The dominant mechanism of IL-15 action is known as transpresentation in which IL-15 and IL-15 R alpha are coordinately expressed on the surface of one cell and interact with complexes of IL-2 R beta / gamma c on adjacent cells (9). This enables cells to respond to IL-15 even if they do not express IL-15 R alpha (8, 10). Soluble IL-15-binding forms of IL-15 R alpha can be generated by proteolytic shedding or alternate splicing (11‑13). These molecules retain the ability to bind tightly to IL-15 and can either inhibit or augment IL-15 function (5, 12, 13). Consistent with its shared use of IL-2 receptor subunits, IL-15 induces IL-2-like effects in lymphocyte development and homeostasis (3). It is particularly important for the maintenance and activation of NK cells and CD8+ memory T cells (3). IL-15 also exerts pleiotropic effects on other hematopoietic cells and non-immune cells (2). Ligation of membrane-associated IL-15/IL-15 R alpha complexes induces reverse signaling that promotes cellular adhesion, tyrosine phosphorylation of intracellular proteins, and cytokine secretion by the IL-15/IL-15 R alpha expressing cells (14, 15).
