背景信息

Interferon gamma (IFN γ) is a type II interferon that confers immunity to bacterial, viral and protozoan infections. In its active form, IFN γ is a glycosylated, non-covalently linked homodimer of 29-32 kDa subunits. It is produced by a number of immune cell types, including natural killer cells, natural killer T cells and effector lymphocyte T cells, in response to antigenic and inflammatory stimuli. The IFN-γ dimer binds to its cognate receptor, which has two subunits: IFN-γR1, the ligand binding chain (α chain), and IFN-γR2, the signal transducing chain (β chain). Binding to the receptor activates the JAK/STAT pathway, which in turn activates IFN-γ responsive genes. While IFN γ can inhibit viral replication, it also acts as an immunomodulator and immunostimulator by increasing the surface expression of class I MHC proteins.
