WebNov 26, 2024 · Given that IFN-γ signaling is mediated by STAT1 in most cases , we wanted to confirm the involvement of STAT1 in the regulation of Mda5 expression by IFN-γ. Therefore, we stimulated macrophages from STAT1-deficient mice with IFN-γ for a range of time periods. RNA was then extracted and Mda5 expression was determined by RT-PCR. WebSep 1, 2024 · Interferon-gamma (IFN-γ) is one of the most essential cytokines in the inflammatory response and immune response. It is mainly produced by natural killer (NK) cells in innate immune system and T cells in adaptive immune system [15]. Like most cytokines, IFN-γ has two sides.
