Dysbiosis-induced IL-33 contributes to impaired antiviral immunity in the genital mucosa. Blockade of chronic type I interferon signaling to control persistent LCMV infection. Accompanying CD-ROM has same title as book. Further, Marshall et al. Type I interferon (IFN-I) then directly targets these newly generated DCs to program their potent T cell immunosuppressive functions while simultaneously inhibiting conventional DCs with T cell stimulating capacity. Annu Rev Med. Activation of the p38 mitogen-activated protein kinase by type I interferons. Inflammatory monocytes are rapidly recruited to sites of infection, where they can then stimulate local and migrating immune cell antiviral function, promote inflammation, and differentiate into macrophages and DCs (34). Induction of innate immunity against herpes simplex virus type 2 infection via local delivery of Toll-like receptor ligands correlates with beta interferon production. Aside from type I IFN, IFN-γ has a number of immunoregulatory functions that serve to optimize the antiviral response and limit overzealous responses that could lead to collateral damage. doi: 10.1172/JCI40093, 68. Schroder K, Hertzog PJ, Ravasi T, Hume DA. The defense against an infection is led by NK cells when they secrete the interferon, whereas the adaptative immune response is directed by mainly T lymphocytes with interferon-gamma. No use, distribution or reproduction is permitted which does not comply with these terms. Uddin S, Lekmine F, Sharma N, Majchrzak B, Mayer I, Young PR, et al. It is known, from different studies, that a scarcity of this homodimer or its receptor promotes colorectal cancer development. (2006) 80:9943–50.

In conjunction with GM-CSF, IFN-γ was shown to differentiate monocytes into myeloid derived suppressor cells (MDSCs) in vitro (92). 2. effects on gene expression, not all of which are understood. Platanias LC. Apart from macrophages and NK cells, the production of the interferon-gamma by T cells is controlled by these two interleukin. An antibody targeting human IFNAR has recently been developed to block this signature with therapeutic benefit (97). Both chains belong to the class II cytokine receptor family. (1996) 271:4988–92. IFN-γ, like type I IFN, promotes antiviral immunity through its regulatory effects on the innate immune response and acts as a key link between the innate immune response and activation of the adaptive immune response (3). Werner JM, Serti E, Chepa-Lotrea X, Stoltzfus J, Ahlenstiel G, Noureddin M, et al. Duerr et al. Though administration of pegylated IFN-α2 therapy resulted in an increased NK cell activation, TRAIL, and CD107a receptor expression in HCV-infected individuals, there was a concomitant reduction in IFN-γ+ NK cells within the PBMC compartment (57, 58).

This edition has been updated and revised with new figures and text. surface expression of MHC, block complement activation, prevent the host cell cause kidney, liver, bone marrow and heart toxicity. In the context of HSV-2 infection, for example, there is an initial wave of IFN-β production at 12 h post-infection, followed by both IFN-β and IFN-α production at 48 h post-infection (19, 20). The impact of antiviral IFN-γ on antigen presenting cells (APCs) is to enhance stimulation of the adaptive antiviral response to both clear the infection and generate memory as a safe-guard for future infections (78, 79). Mechanisms of type-I- and type-II-interferon-mediated signalling. This enabled researchers (2015) 15:87–103. Protein kinase R, for example, inhibits cellular translational functions (1). Stifter SA, Bhattacharyya N, Pillay R, Florido M, Triccas JA, Britton WJ, et al. The book starts with an analysis of the profound effect that viral epidemics had on world history resulting in demographic upheavals by destroying total populations.

Interferons-alpha and -beta The initial type I IFN wave subsequently induces IRF7 phosphorylation and results in a positive feedback loop of increasing type I IFN release. Table 1. Down regulation of macrophage IFNGR1 exacerbates systemic L. monocytogenes infection. Within the type I IFN literature, a theme has emerged wherein acute type I IFN production promotes beneficial antiviral responses, while chronic type I IFN production can have a suppressive and deleterious effect on the immune response. RNA viruses induce interferon but RNA viruses tend to induce higher levels. These interferons induce about Advances in scientific instrumentation and technique have allowed for greater understanding and visualization of not only the structure but also the mechanisms of the various types of inteferons. IFNGR2 is an intracellular region which have a noncontiguous binding motif for recruitment of Jak2 kinase for signaling. found that GM-CSF altered the signaling pathway of IFN-γ allowing it to differentiate monocytes into MDSCs (92). Type I and type II interferons (IFN) are central to both combating virus infection and modulating the antiviral immune response. Additionally, pre-treatment of influenza-infected mice with the same dose of different type I IFN subtypes resulted in varying levels of virus replication, with IFN-α5 and IFN-α6 having the greatest reduction in viral load (70). Interferon and IL-27 antagonize the function of group 2 innate lymphoid cells and type 2 innate immune responses. These cells secrete IFNγ only when activated, especially in presence of IL-2 and IL-12. Beyond their antiviral effects, a growing amount of evidence suggests that type I and type II IFNs have immunoregulatory functions that are critical for dampening immunopathogenic mechanisms and minimizing collateral damage from the infection. Interferon-γ is the type II interferon. This early production of type I IFN is critical for induction of both an antiviral response within infected and target cells, as well as activation of innate immune cells that will ultimately serve to control virus replication and activate the adaptive immune response to both clear the infection and generate memory to create a rapid response against future infections (21). (2011) 108:284–9. doi: 10.1016/j.cellimm.2011.03.007, 17. demonstrates that IFN-γ plays a critical role in not only polarizing macrophages to an M1 phenotype, but actively suppresses the M2 polarization pathway (87). and Moro et al.

(4) A second wave of type I IFNs, including both IFN-α and IFN-β, are detected at 48 h post-infection. 14. IFN-γ has some anti-viral and anti-tumor effects, but these are generally weak. J Biol Chem. As they are produced rather early on during an infection, type I IFNs are also essential for activating the antiviral innate immune response, such as natural killer (NK) cell effector functions (2). Type I IFN has been shown to act directly on NK cells to induce their release of IFN-γ in the context of adenovirus, vaccinia virus, and LCMV infections, whereas other evidence suggests that type I IFN stimulates DCs to trans-present IL-15 to activate NK cells in MCMV infection (2, 40–44). Cell (2011) 146:621–32. Nevertheless, IFN-γ is implicated in many function within immune system as immunoregulatory, antiviral and anti-tumor properties. Studies into IFNγ signaling have provided insight into the general concepts of receptor signaling, receptor internalization, regulation of distinct signaling pathways, and transcriptional regulation. Type I interferons produced by dendritic cells promote their phenotypic and functional activation. interferon-induced protein kinase, inhibit NK function, interfere with cell Arthritis Rheumatol. Type I IFN was also found to suppress pro-inflammatory NOS2+ Ly6Clo monocyte function (36). Inhibition of herpes simplex virus type 1 replication. These new interferons were later proven to have anti-viral effects, and were thus formally classiied as type III interferons. (2009) 78:514–22.

McNab F, Mayer-Barber K, Sher A, Wack A, O'Garra A, and Type I interferons in infectious disease Nat Rev Immunol. In the context of RSV infection, Stat1−/− mice, a transcription factor downstream of both type I and type II IFNs, led to increased lung pathology because of increased cytokine production from ILC2s and ILC3s (90). In the context of virus infection, however, we believe that IFN-γ released during the innate immune response has more of a supportive role in this respect as it is less potent in its effects in comparison to type I IFNs. |, Creative Commons Attribution License (CC BY), Department of Pathology and Molecular Medicine, McMaster Immunology Research Centre, McMaster University, Hamilton, ON, Canada.
