Interferon-γ, human (hIFN-γ)

Uses

Interferon-γ, human (hIFN-γ) has been used to stimulate mesenchymal stem cells (MSCs). It has also been used as a supplement Dulbecco′s modified Eagle′s medium/Ham′s medium for the cultivation of human colorectal carcinoma cell line T84 cells.

General Description

IFN-γ is produced by T-lymphocytes stimulated by antigen or by T-cell mitogens. Under nondenaturating conditions its molecular weight values range from 32,000 to 73,000 indicating that recombinant human IFN-γ exists as a dimer or higher oligomers.

Biochem/physiol Actions

Interferon-γ (IFN-γ) is an essential component of acquired immunity. A broad range of biological activities has been attributed to IFN-γ (e.g., the establishment of the antiviral state, immunoregulatory functions, antiproliferative effects and inhibition of cell growth). The anti-proliferative effects of IFN-γ are superior to those of either IFN-α or IFN-β. Growth inhibition is dependent on cell type, dose, and length of exposure. One of IFN-γ′s primary functions might be as an immunoregulatory agent: IFN-γ induces MHC antigens on many cells, Fc-receptors on monocytes and macrophages, IL-2 receptors on T-cells, enhances activity of macrophages, polymorphonuclear leukocytes, T-lymphocytes, and NK-cells (MAF), and is also involved in the regulation of B-cells.
