Immunomodulatory activity of interferon-beta
Multiple sclerosis (MS) is a complex disorder of the central nervous system that appears to be driven by a shift in immune functioning toward excess inflammation that results in demyelination and axonal loss. Beta interferons were the first class of disease-modifying therapies to be approved for patients with MS after treatment with this type I interferon improved the course of MS on both clini...
متن کاملInterferon (IFN)-λ Takes the Helm: Immunomodulatory Roles of Type III IFNs
Type III interferons (IFNs) (or IFN-λ) are the latest addition to the IFN family. Even though they share little protein homology with type I IFN, both exhibit remarkable functional similarities: each can be induced in response to viral infections, and both lead to Janus kinases (JAK) and signal transducer and activator of transcription (STAT) activation. The JAK/STAT pathway induces antiviral r...
متن کاملDifferential inhibition of type I interferon induction by arenavirus nucleoproteins.
We have documented that the nucleoprotein (NP) of the prototypic arenavirus lymphocytic choriomeningitis virus is an antagonist of the type I interferon response. In this study we tested the ability of NPs encoded by representative arenavirus species from both Old World and New World antigenic groups to inhibit production of interferon. We found that, with the exception of Tacaribe virus (TCRV)...
متن کاملInhibition by interferon of delayed-type hypersensitivity in the mouse.
The effect of interferon on delayed-type by persensitivity to picryl chloride and sheep erythrocytes was examined in the mouse. When administered to sensitized animals on the day before or the day of challenge, tissue culture interferon inhibited both the ear swelling induced by pieryl chloride and footpad swelling induced by sheep erythrocytes. Newcastle disease virus, when injected into sensi...
متن کاملActivation of Type I and III Interferon Response by Mitochondrial and Peroxisomal MAVS and Inhibition by Hepatitis C Virus.
Sensing viruses by pattern recognition receptors (PRR) triggers the innate immune system of the host cell and activates immune signaling cascades such as the RIG-I/IRF3 pathway. Mitochondrial antiviral-signaling protein (MAVS, also known as IPS-1, Cardif, and VISA) is the crucial adaptor protein of this pathway localized on mitochondria, peroxisomes and mitochondria-associated membranes of the ...
