Monokine induced by interferon-gamma (MIG), or CXCL9, is a member of the CXC chemokine family. MIG is closely related to two other chemokines: CXCL10 and CXCL11, all of which signal through the CXCR3 receptor (Ding et al.). MIG is secreted by a variety of immune cells including T cells, NK cells, dendritic cells, macrophages, and eosinophils, as well as non-immune cells including hepatic stellate cells, preadipocytes, thyrocytes, endothelial cells, tumor cells, fibroblasts, and glial cells of the central nervous system. MIG has also been shown to act as a chemoattractant for activated T cells and for tumor-infiltrating leukocytes (TILs), but not for neutrophils or for monocytes. MIG has also been reported to be both a tumor suppressor and tumor promoter in various types of cancer.

Recently, a number of cytokines belonging to the interleukin (IL)-17 family have been identified. These are termed as IL-17B, IL-17C and IL-17E. IL-17 is a potent proinflammatory cytokine that plays roles in a number of diseases including rheumatoid arthritis , multiple sclerosis , and promotion of tumor growth. IL-17B, C, and E like IL-17 are able to induce proinflammatory responses. However, they do not bind to the IL-17 receptor suggesting that additional IL-17R related receptor might exist. Receptor for IL-17B and IL-17E has been independently isolated by Shi, et al and Lee, et al. and has been designated as EV127 (in mouse) and IL-17Rh1 (in human), respectively. IL-17E induces activation of NF-κB pathway and like IL-17 also induces production of IL-8. The IL17 proteins are a family of potent cytokines that act to induce proinflammatory responses. Studies have shown that IL17E binds strongly to IL17RB. Receptor binding of ligand has been shown to lead to the activation of nuclear factor kappa-B and production of IL8. Exposure of mice to IL17 resulted in a Th-2 like response characterized by increased serum IgE, IgG1 and IgA levels, blood eosinophilia, increased lymphocytes and neutrophils, and pathological changes in the tissues that included eosinophilic infiltrates, increased mucus production, B-lymphocyte hyperplasia and epithelial cell hyperplasia/hypertrophy.

Glutathione is the major low molecular weight thiol compound of the living plant or animal cell. It is a tripeptide with a gamma peptide linkage between the amine group of cysteine (which is attached by normal peptide linkage to a glycine) and the carboxyl group of the glutamate side-chain. It is an antioxidant, preventing damage to important cellular components caused by reactive oxygen species such as free radicals and peroxides. The sulfhydryl (thiol) group (SH) of cysteine serves as a proton donor and is responsible for the biological activity of glutathione.
Glutathione suppresses human immunodeficiency virus expression in chronically infected monocytic cells. It is a useful tripeptide involved in many aspects of metabolism, including transport of g-glutanyl amino acids and reductive cleavage of disulfide bonds.
Endogenous antioxidant that plays a major role in reducing reactive oxygen species formed during cellular metabolism and the respiratory burst. Glutathione-S-transferase catalyzes the formation of glutathione thioethers with xenobiotics, leukotrienes, and other molecules that have an electrophilic center. Glutathione also forms disulfide bonds with cysteine residues in proteins. Via these mechanisms, it can have the paradoxical effect of reducing the efficacy of anti-cancer agents.

Interleukin 12 (IL-12p70) is a heterodimeric cytokine composed of p35 and p40 subunits. IL-12 is produced by monocytes, macrophages, dendritic cells, neutrophils, and B cells in response to bacterial products and cytokines such as IFN-γ. The IL-12 receptor is expressed on T, NK, and dendritic cells. Upon binding, IL-12 initiates signaling via the JAK/STAT signaling pathway and stimulates NK, B, and T cells to produce IFN-γ (Watford et al.). It also regulates cytokine synthesis, proliferation of T and NK cells, and stimulates differentiation of CD4+ and CD8+ T cells (Germann and Rüde). Mice that are deficient in IL-12 are susceptible to many intracellular pathogens and have impaired IFN-γ secretion, Th1 differentiation, and NK cytolytic activity; however, Th2 development and IL-4 production are enhanced (Watford et al.).
