The strong impact of interleukin 28B (IL28B) polymorphisms on sustained virological response (SVR) after peginterferon and ribavirin treatment in patients with chronic hepatitis C (CHC) is well-known. We investigated IL28B variability and hepatic expression of IP10, IFI27, ISG15, and MX1 in CHC patients, the relation of each with their clinical characteristics, and how they associated with resp...
Various endometrial genes in ruminant ungulates are regulated by conceptus interferon tau (IFNT). However, the effect of each IFNT isoform has not been carefully evaluated. In this study, the effects of 2 IFNT isoforms, paralogs found in utero, and interferon alpha (IFNA) on uterine epithelial and Mardin-Darby bovine kidney (MDBK) cells were evaluated. Expression vectors of the bovine interfero...
Mx proteins are a family of large GTPases that are induced exclusively by interferon-α/β and have a broad antiviral activity against several viruses, including influenza A virus (IAV). Although the antiviral activities of mouse Mx1 and human MxA have been studied extensively, the molecular mechanism of action remains largely unsolved. Because no direct interaction between Mx proteins and IAV pr...
BACKGROUND There are two biotypes of feline coronavirus (FCoV): the self-limiting feline enteric coronavirus (FECV) and the feline infectious peritonitis virus (FIPV), which causes feline infectious peritonitis (FIP), a fatal disease associated with cats living in multi-cat environments. This study provides an insight on the various immune mediators detected in FCoV-positive cats which may be r...
Type I interferons have been typically studied for their effects in the context of bacterial or viral infections. However in this report, we provide evidence that Interferon-alpha (IFN-α) expressing cells are present in the thymus in the absence of infection. We show that pDC express the highest level of IFN-α and that MxA, which is exclusively expressed after engagement of the type I IFN recep...
Human MxA protein inhibits LaCrosse virus (LAC virus; family Bunyaviridae) replication in vertebrate cells and MxA-transgenic mice. LAC virus is transmitted to humans by Aedes triseriatus mosquitoes. In this report, we have shown that transfected mosquito cells expressing the human MxA cDNA are resistant to LAC virus but permissive for Sindbis virus (family Togaviridae) infection.
Background: In the last decade due to emerge and remerge of influenza viruses, quality improvement of vaccines to increase immune responses in target populations have been more necessary. The potential of biologic adjuvant to stimulate and induce immune system is the basis of modern researches in prevention and controlling program of infectious diseases. In this study, the effect of the coding ...
INTRODUCTION Interferon-β (IFNß) is the first-line treatment for relapsing-remitting multiple sclerosis. Myxovirus resistance protein A (MxA) is a marker of IFNß bioactivity, which may be reduced by neutralizing antibodies (NAbs) against IFNß. The aim of the study was to analyze the kinetics of MxA mRNA expression during long-term IFNβ treatment and assess its predictive value. METHODS A pros...
The induction of an interferon-induced antiviral state is a powerful cellular response against viral infection that limits viral spread. Here, we show that a preexisting antiviral state inhibits the replication of influenza A viruses in human A549 cells by preventing transport of the viral genome to the nucleus and that the interferon-induced MxA protein is necessary but not sufficient for this...
