Interferon regulatory factor 3 is a key regulation factor for inducing the expression of SAMHD1 in antiviral innate immunity
SAMHD1 is a type I interferon (IFN) inducible host innate immunity restriction factor that inhibits an early step of the viral life cycle. The underlying mechanisms of SAMHD1 transcriptional regulation remains elusive. Here, we report that inducing SAMHD1 upregulation is part of an early intrinsic immune response via TLR3 and RIG-I/MDA5 agonists that ultimately induce the nuclear translocation ...
متن کاملVaccinia virus and Cowpox virus are not susceptible to the interferon-induced antiviral protein MxA
MxA protein is expressed in response to type I and type III Interferon and constitute an important antiviral factor with broad antiviral activity to diverse RNA viruses. In addition, some studies expand the range of MxA antiviral activity to include particular DNA viruses like Monkeypox virus (MPXV) and African Swine Fever virus (ASFV). However, a broad profile of activity of MxA to large DNA v...
متن کاملInterferon-induced antiviral protein MxA interacts with the cellular RNA helicases UAP56 and URH49.
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...
متن کاملMitochondria and antiviral innate immunity.
Mitochondria, dynamic organelles that undergo continuous cycles of fusion and fission, are the powerhouses of eukaryotic cells. Recent research indicates that mitochondria also act as platforms for antiviral immunity in vertebrates. Mitochondrial-mediated antiviral immunity depends on activation of the retinoic acid-inducible gene I (RIG-I)-like receptors signal transduction pathway and the par...
متن کاملSensing and Signaling in Antiviral Innate Immunity
Viruses are detected by the innate immune system, leading to the initiation of the anti-viral immune response via the production of type I interferons and inflammatory cytokines such as interleukin-1. Remarkable progress has been made over the past few years towards understanding the contribution of Toll-like receptors, RIG-I like receptors, NOD-like receptors and HIN-200 family members to vira...
