Biochem/physiol Actions
Interferons (IFNs) are cytokines that are secreted in response to viral or bacterial infections and tumorigenesis. IFN-γ binds to specific receptor complex consisting of IFNγR1 and IFNγR2. There are many pathways that are mediated by IFN-γ binding such as JAK/STAT1, AP-1, NF-κB, STAT3 and STAT5. IFN-γ is pleotropic and performs various functions related to immune response, inflammation, differentiation and activation of T cells, cell cycle and apoptosis.
Physical form
Lyophilized from a 0.2 μm filtered solution in phosphate buffered saline containing 5% trehalose.

Rinderpest virus (RPV) is a paramyxovirus closely related to the human pathogen Measles virus. It causes severe disease in cattle, buffalo, and some wild animals; although it can infect humans, it does not cause disease. Here, we demonstrate that RPV
Interferons are cytokines that have antiviral, antiproliferative and immunomodulatory effects. Because of these important properties, in the past two decades, major research efforts have been undertaken to understand the signalling mechanisms through which these cytokines induce their effects. Since the

Interferon-gamma (IFN-gamma) coordinates a diverse array of cellular programs through transcriptional regulation of immunologically relevant genes. This article reviews the current understanding of IFN-gamma ligand, receptor, signal transduction, and cellular effects with a focus on macrophage responses and to a

The x-ray crystal structure of recombinant human interferon-gamma has been determined with the use of multiple-isomorphous-replacement techniques. Interferon-gamma, which is dimeric in solution, crystallizes with two dimers related by a noncrystallographic twofold axis in the asymmetric unit. The protein is

Interferon-γ is a cytokine whose biological activity is conventionally associated with cytostatic/cytotoxic and antitumor mechanisms during cell-mediated adaptive immune response. It has been used clinically to treat a variety of malignancies, albeit with mixed results and side effects that can
