Application
γ-Interferon has been used to assess the response of wild-type and cytosolic phospholipase A2 (cPLA2)-deficient cells to IFN-mediated signals. It has also been used to study the signaling pathway associated with IFN-γ and to explore the potential role of β-Arrestin1 in the dephosphorylation of signal transducer and activator of transcription 1 (STAT1).
Biochem/physiol Actions
Interferon-gamma (IFN-γ), a proinflammatory cytokine, exhibits a significant impact on innate and adaptive immunity in terms of combatting intracellular infections and facilitating tumor control. It has a significant impact on various immunological pathways. IFN-γ influences the following biological processes:
Antigen Processing and Presentation: IFN-γ enhances the expression of molecules involved in antigen presentation. This helps in the efficient activation of T cells, leading to the initiation of adaptive immunity.
Reactive Oxygen Species (ROS): IFN-γ stimulates the production of ROS by promoting the assembly of NADPH oxidase subunits. These ROS possess strong microbicidal effects, aiding in the defense against invading pathogens.
Autophagy: IFN-γ induces the expression of proteins involved in autophagy, facilitating the clearance of intracellular pathogens and contributing to immune defense.
Apoptosis: IFN-γ triggers apoptotic cell death by increasing the expression of molecules associated with the apoptotic pathway.
Cell Migration and Leukocyte Traffic: IFN-γ promotes the expression of chemokines and adhesion molecules, facilitating immune cell migration and contributing to the initiation of inflammatory responses.
Antiviral Mediators: By inducing the expression of various antiviral proteins, IFN-γ counteracts viral infections at multiple stages of the viral life cycle.

Signal transducer and activator of transcription 1 (STAT1) is activated by tyrosine phosphorylation upon interferon-γ (IFNγ) stimulation, which results in the expression of genes with antiproliferative and immunomodulatory functions. The inactivation of STAT1 occurs through tyrosine dephosphorylation by the tyrosine
