Interferons (IFNs) are cytokines that are secreted in response to viral or bacterial infections and tumorigenesis. There are two types of IFNs, type I (IFN-α and IFN-β) and type II (IFN-γ). 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. The most studied function of IFN-γ is priming the antigen presenting cells by upregulating major histocompatibility (MHC) Class I molecules.
IFN-γ has clinical applications in autoimmune diseases (rheumatoid arthritis), multiple sclerosis, cancer, HIV and fungal infections
Anti-Interferon-γ recognizes human Interferon-γ. It does not bind specifically to mouse, hamster or bovine IFN-γ.
