Description:
RANTES (regulated upon activation, normal T cell expressed and secreted), also known as CCL5, is a member of the CC family of chemokines and is able to recruit leukocytes to sites of inflammation (Schall <i>et al.</i>). RANTES is secreted by T lymphocytes, macrophages, platelets, synovial fibroblasts, tubular epithelium, and certain types of tumor cells (Aldinucci and Colombatti; Soria and Ben-Baruch). This chemokine exerts its effect by interacting with the chemokine receptors CCR1, CCR3, CCR4, and CCR5. RANTES plays an active role in recruiting a variety of leukocytes into inflammatory sites, including T cells, macrophages, eosinophils, and basophils. In collaboration with certain cytokines that are released by T cells such as IL-2 and IFN-γ, RANTES also induces the activation and proliferation of NK cells to generate CC chemokine-activated killer cells, which are highly cytolytic (Lv <i>et al.</i>; Maghazachi <i>et al.</i>). It has been shown that RANTES produced by CD8+ T cells inhibits HIV infection of primary human peripheral blood mononuclear cells (Appay and Rowland-Jones; Cocchi <i>et al.</i>).

Description:
Nerve growth factor (NGF)-beta is a prototypical member of the neurotrophin family and has a role in the survival and growth of neural cells, regulating cell growth, promoting differentiation into neurons, and neuron migration. The beta subtype of NGF is biologically active in comparison to the alpha-2 and gamma-2 subtypes. NGF-beta in its secreted form can bind to tyrosine kinase A (TrkA) receptor with high affinity and to p75 (NTR) with low affinity (Levi and Alemà; Sofroniew <i>et al.</i>). NGF has been shown to possess pro-inflammatory and pro-fibrogenic properties (Micera <i>et al.</i>). It has also been shown that overexpression of NGF-beta promotes differentiation of bone marrow mesenchymal stem cells into neurons through regulation of AKT and MAPK pathways (Yuan <i>et al.</i>).

Description:
Interleukin 15 (IL-15) is a four-alpha helix bundle cytokine with many similar properties to IL-2. The IL-15 receptor is a heterotrimeric receptor composed of IL-15Ra (the high-affinity receptor for IL-15), as well as IL-2/15Rb (CD122) and common gamma chain (CD132). IL-15 binds to IL-15Rα receptor and can then be presented in trans to IL-2/15Rb and common gamma chain on other cells. Trans-presentation is thought to be the major mechanism by which IL-15-mediated responses occur in mice, although may not be necessary in humans (Castillo <i>et al.</i>). The cytoplasmic domains of IL-2/15Rb and common gamma chain mediate signaling to activate JAK/STAT and PI3K pathways. IL-15 supports the survival and proliferation of naïve CD4+ and CD8+ T cells, and promotes homeostasis of memory T cells. IL-15 also promotes the survival and differentiation of NK cells and regulates their cytolytic activity (Ma <i>et al.</i>). This product is animal component-free.

Description:
Fibroblast growth factor 8B (FGF-8B) is a member of the fibroblast growth factor (FGF) family and is an isoform of FGF-8. Cytokines in the FGF family possess broad mitogenic and cell survival activities (Folkman and Klagsbrun; Kimelman and Kirschner) and are involved in a variety of biological processes, including cell proliferation, differentiation, survival, and apoptosis (Folkman and Klagsbrun; Klagsbrun; Rifkin and Moscatelli). FGF-8B signals through FGF receptors (FGFRs) to activate PI3K and MAPK pathways. FGF-8B regulates gastrulation, epithelial-mesenchymal transition, and mesenchymal to epithelial differentiation during embryonic development. FGF-8B has also been found in peripheral blood leukocytes and healthy bone marrow samples (Mattila and Härkönen). FGF-8B has mitogenic effects on somatic cells in the germinal epithelium and is expressed in adult mouse ovarian cells and tissues, which suggests that it regulates maturation of oocytes and seminiferous epithelium in testes (Valve <i>et al.</i>). This product is animal component-free.

Description:
Fibroblast growth factor 10 (FGF-10) is a member of the fibroblast growth factor (FGF) family predominantly expressed by mesenchymal fibroblasts during embryonic development (Emoto <i>et al.</i>; Igarashi <i>et al.</i>). It binds with high affinity to fibroblast growth factor receptor 2-IIIb (FGFR2-IIIb), and also has a weaker affinity for FGFR1-IIIb (Beer <i>et al.</i>). FGF-10 and FGF-7 have similar receptor binding properties and target cell specificities but are differentially regulated by components of the extracellular matrix (Emoto <i>et al.</i>; Igarashi <i>et al.</i>). FGF-10 has been shown to mediate epithelial-mesenchymal interactions, which are essential to lung development (Sekine et al; Ware and Matthay). FGF-10 also has a role in mobilisation and proliferation of lung-resident mesenchymal stem cells (MSCs) and protection and repair against acute lung injury (Tong <i>et al.</i>; Ware and Matthay), as well as endodermal differentiation of human pluripotent stem cells to insulin-producing pancreatic-like cells (Takeuchi <i>et al.</i>).

Description:
Interferon-gamma (IFN-γ), also known as type II interferon, is produced by T and NK cells, and in smaller amounts by dendritic cells and macrophages. IFN-γ is controlled by cytokines such as IL-12 and IL-18 secreted in response to infection (Schroder <i>et al.</i>). IFN-γ binds to a receptor complex and initiates signal transduction via the JAK/STAT pathway; this culminates in the transcription and activation of many genes that control a diverse array of immunological functions (de Weerd and Nguyen; Krause <i>et al.</i>). IFN-γ stimulates the antimicrobial and anti-tumor activity of macrophages, NK cells, and neutrophils (Billiau and Matthys) by promoting the activation of microbial effector functions such as production of reactive oxygen species, NO intermediates, and complement (Schroder <i>et al.</i>). IFN-γ enhances MHC class I and II expression in dendritic cells and mononuclear phagocytes, as well as the production of IL-12 by dendritic cells. In B cells, IFN-γ stimulates survival and growth in both mouse and human cells, and redirects B cells from proliferation towards differentiation. IFN-γ favors the development of Th1 vs Th2 cells and stimulates monocyte differentiation and function (Schroder <i>et al.</i>). This product is animal component-free.

Description:
Fibroblast growth factor (FGF) 9 is a pleiotropic member of the FGF family. FGFs are heparin-dependent regulators of cell proliferation and differentiation (Itoh and Ornitz). FGF-9 signals by binding FGFR3 (IIIb) and the IIIc splice variants of the FGFR1, FGFR2, and FGFR3 receptors (Santos-Ocampo <i>et al.</i>; Mohammadi <i>et al.</i>; Plotnikov <i>et al.</i>). In mice, deletion of FGF-9 is lethal and expression of FGF-9 affects development of the skeleton, cerebellum, lungs, heart, vascular system, digestive tract, and testes (Colvin <i>et al.</i>; Harada <i>et al.</i>; Lin <i>et al.</i>). Altered levels of FGF-9 have also been reported in various types of human cancers (Leushacke <i>et al.</i>; Abdel-Rahman <i>et al.</i>).

Description:
Tumor necrosis factor-α (TNF-α) is a pro-inflammatory cytokine that activates NF-kB, MAPK, and PI3K/AKT pathways. Activated T cells and macrophages are the primary producers of TNF-α in response to inflammation and infectious conditions. Many other cell types have been shown to produce TNF-α, among them B cells, NK cells, mast cells, neutrophils, dendritic cells, microglia, endothelial cells, smooth muscle cells, cardiomyocytes, and fibroblasts. TNF-α has cytotoxic effects on cancer cells in vitro by stimulating anti-tumor immuno- suppressive responses. TNF-α stimulates expression of E- and P-selectins, thus facilitating adhesion of neutrophils, monocytes, and memory T cells to activated platelets and endothelial cells (Zelová and Hosek). Other effects of TNF-α include vasodilatation and edema formation. This product is animal component-free.
