At IFN doses of 3 X 10(6), 10(7), and 3 X 10(7) U, a negative correlation existed between the amount of IFN injected and the average extent of NK cell activation. Role of IFN-alpha/beta and IL in the activation of natural killer cells and interferon-gamma production during experimental infection with Trypanosoma cruzi. During experimental infection this cytokine is produced early, mainly by natural killer (NK) cells and later by T cells. Interferon-alpha activates cytotoxic function but inhibits interleukinmediated proliferation and tumor necrosis factor-alpha secretion by immature human natural killer cells. Author information: Natural killer (NK) cells play an important role in host defense mechanisms against infection and neoplasia.
It is not clear how type I IFN regulates NK cell activation in response to live They are a family of cytokines that constitute 13 and 17 IFN-α. The peripheral NK cells from chronic hepatitis patients with HCV genotype 1 and high virus titers were activated using a Toll-like receptor (TLR) 4 ligand and IFN-α. The genotyping of the polymorphisms in the IL28B gene region (rs) on chromosome 19 was performed on the DNA collected from each patient. Author Summary The innate immune response mediated by cells such as natural killer (NK) cells can contribute to immunity against viral.

Our own preclinical data also demonstrate that activation of NK cells is . DC production of TNF-α and IL were measured by flow cytometry. on NK cells to promote their activation, cell cycle entry, and the type I IFN-α receptor (Ifnar−/−) or STAT1 (which signals downstream of IFN.
