How do interferons function

WebInterferons (IFNs) are a family of cytokines, or protein hormones, which modulate the immune response and provide resistance to viral infection. The effects of IFN are mediated through cell-surface receptors, which recognize extracellular IFN and activate cellular signaling pathways, ultimately leading to gene induction and repression. WebJan 17, 2024 · Type-II interferons. Interferon-γ is a type-II interferon. NK cells, cytotoxic T cells and Th1 cells produce interferon-γ in response to IL-12 and IL-18. Interferon-γ activates macrophages and increases their ability to kill pathogens by enhancing pinocytosis and lysosome function. Type-II interferons also upregulate MHC II expression.
