TLDR
Comparison of mice lacking either type I or type II IFN receptors showed that, at least in response to some viruses, both IFN systems are essential for antiviral defense and are functionally nonredundant.Abstract:
Mice lacking the known subunit of the type I interferon (IFN) receptor were completely unresponsive to type I IFNs, suggesting that this receptor chain is essential for type I IFN-mediated signal transduction. These mice showed no overt anomalies but were unable to cope with viral infections, despite otherwise normal immune responses. Comparison of mice lacking either type I or type II IFN receptors showed that, at least in response to some viruses, both IFN systems are essential for antiviral defense and are functionally nonredundant.read more

Interferon-γ: an overview of signals, mechanisms and functions
TL;DR: The current understanding of IFN‐γ ligand, receptor, ignal transduction, and cellular effects with a focus on macrophage responses and to a lesser extent, responses from other cell types that influence macrophages function during infection are reviewed.
Journal ArticleDOI
Cellular responses to interferon-gamma.
TL;DR: Much of the cellular response to IFN-gamma can be described in terms of a set of integrated molecular programs underlying well-defined physiological systems, for example the induction of efficient antigen processing for MHC-mediated antigen presentation, which play clearly defined roles in pathogen resistance.

Antiviral Actions of Interferons
TL;DR: Tremendous progress has been made in understanding the molecular basis of the antiviral actions of interferons (IFNs), as well as strategies evolved by viruses to antagonize the actions of IFNs.

TL;DR: The results of this trio of studies suggest that the location, timing, and duration of IFN exposure are critical parameters underlying the success or failure of therapeutics for viral respiratory infections.
Journal ArticleDOI
Interferon-inducible antiviral effectors
TL;DR: This Review discusses four main effector pathways of the IFN-mediated antiviral response: the Mx GTPase pathway, the 2′,5′-oligoadenylate-synthetase-directed ribonuclease L pathways, the protein kinase R pathway and the ISG15 ubiquitin-like pathway.

Endogenous regulation of macrophage proliferative expansion by colony-stimulating factor-induced interferon
TL;DR: The effect of the antiserum was lost in cultures depleted of adherent cells, an indication that an adherent regulatory cell (or cells) in the marrow limits mononuclear phagocyte proliferation by producing antiproliferative interferon in response to high levels of specific growth factor.

125I-labelled Human Interferons Alpha, Beta and Gamma: Comparative Receptor-binding Data
TL;DR: Direct comparative binding studies support the hypothesis that the receptor system for IFN-gamma is unrelated to theIFN-alpha/beta system.

Single amino acid changes that render human IFN-alpha 2 biologically active on mouse cells.
TL;DR: It is argued that three residues in IFN‐alpha 2 are involved in direct contacts with the mouse interferon receptor and modify its activity on mouse cells by up to 400‐fold.

Antiviral protection by CD8+ versus CD4+ T cells. CD8+ T cells correlating with cytotoxic activity in vitro are more efficient in antivaccinia virus protection than CD4-dependent IL.

TL;DR: It is shown that CD4+ T cell-dependent IL may mediate antiviral protection, but their efficiency is relatively weak compared with CD8-mediated protection correlating with cytotoxic activity in vitro.

Identification of an interferon in murine placentas.
TL;DR: The detection of a pregnancy-associated elevation of interferon, or aninterferon-like component, in selected reproductive tissues of mice is reported.
