Description	Recombinant Interleukin-15 is a disulfide-linked homodimeric protein consisting of two 115 amino acid residues, and migrates as an approximately 13 kDa protein under non-reducing conditions and reducing conditions in SDS-PAGE. Optimized DNA sequence encoding human Interleukin-15 mature chain was expressed in E. coli.
Background	IL-15 has been shown to be produced by human fetal astrocytes and microglial cells in response to IL-1beta, IFN-gamma, or TNF- alpha and may thus play a role in T-cell mediated immune responses in the human central nervous system. IL-15 stimulates proliferation of the established T-cell line CTLL-2, CD8(+) memory T- cells require IL-15 for proliferation. IL-15 is also able to induce generation of cytolytic cells and LAK cells activity in vitro. IL-15 appears to function as a specific maturation factor for NK-cells and can mimic the bone marrow microenvironment in vitro, which is required for NK- cells to acquire lytic functions. IL-15 induces proliferation of mast cells in the absence of functional IL-2 receptor components and utilizes a receptor of 60-65 kDa that is distinct from known components of T-cell IL-15 receptors. The IL-15 receptor on mast cells recruits JAK2 and STAT5, instead of JAK1, JAK3, and STAT3 and STAT5 that are activated in T-cells. The alpha subunit of the IL-15 receptor (IL-15RA) is structurally related to the alpha subunit of the IL-2 receptor and confers high affinity binding of IL-15 to its receptor. IL-15 binds to the beta and gamma chains of the IL2 receptor, which are known to be required for ligand internalization and signal transduction.
