Bunyamwera bunyavirus nonstructural protein NSs counteracts the induction of alpha/beta interferon [PDF]

, 2002
Production of alpha/beta interferons (IFN-α/β) in response to viral infection is one of the main defense mechanisms of the innate immune system. Many viruses therefore encode factors that subvert the IFN system to enhance their virulence.

Pim Kinase Interacts with Nonstructural 5A Protein and Regulates Hepatitis C Virus Entry [PDF]

Journal of Virology, 2015
ABSTRACT The life cycle of hepatitis C virus (HCV) is highly dependent on host cellular proteins for virus propagation. In order to identify the cellular factors involved in HCV propagation, we performed protein microarray assay using the HCV nonstructural 5A (NS5A) protein as a probe.

NS5A Domain 1 and Polyprotein Cleavage Kinetics Are Critical for Induction of Double-Membrane Vesicles Associated with Hepatitis C Virus Replication

mBio, 2015
Induction of membrane rearrangements in the cytoplasm of infected cells is a hallmark of positive-strand RNA viruses. These altered membranes serve as scaffolds for the assembly of viral replication factories (RFs).

Interferon-inducible protein SCOTIN interferes with HCV replication through the autolysosomal degradation of NS5A

Nature Communications, 2016
Hepatitis C virus (HCV) nonstructural 5A (NS5A) protein is a critical factor for HCV RNA replication. Here the authors show that SCOTIN, an interferon beta-inducible host protein, functions to limit HCV replication by targeting viral protein NS5A for ...

Phytochemical analysis of Berberis lyceum methanolic extract and its antiviral activity through the restoration of MAPK signaling pathway modulated by HCV NS5A

Asian Pacific Journal of Tropical Biomedicine, 2021
Objective: To evaluate the antiviral activity and phytochemicals of selected plant extracts and their effect on the mitogen-activated protein kinase (MAPK) signaling pathway modulated by hepatitis C virus (HCV) nonstructural protein 5A (NS5A). Methods: A

Hepatitis C Virus Non-Structural Protein 5A (NS5A) Disrupts Mitochondrial Dynamics and Induces Mitophagy

Cells, 2019
Mitophagy is a selective form of autophagy, targeting damaged mitochondria for lysosomal degradation. Although HCV infection has been shown to induce mitophagy, the precise underlying mechanism and the effector protein responsible remain unclear. Herein,

Mechanisms of Action of the Host-Targeting Agent Cyclosporin A and Direct-Acting Antiviral Agents against Hepatitis C Virus

Viruses, 2023
Several direct-acting antivirals (DAAs) are available, providing interferon-free strategies for a hepatitis C cure. In contrast to DAAs, host-targeting agents (HTAs) interfere with host cellular factors that are essential in the viral replication cycle ...

Cyclophilin Inhibitors as a Novel HCV Therapy

Viruses, 2010
A critical role of Cyclophilins, mostly Cyclophilin A (CyPA), in the replication of HCV is supported by a growing body of in vitro and in vivo evidence.

Activation of PKR by Bunyamwera virus is independent of the viral interferon antagonist NSs [PDF]

, 2003
Double-stranded RNA (dsRNA) is a by-product of viral RNA polymerase activity, and its recognition is one mechanism by which the innate immune system is activated.

Chikungunya virus nonstructural protein 2 inhibits type I/II interferon-stimulated JAK-STAT signaling [PDF]

, 2010
Chikungunya virus (CHIKV) is an emerging human pathogen transmitted by mosquitoes. Like that of other alphaviruses, CHIKV replication causes general host shutoff, leading to severe cytopathicity in mammalian cells, and inhibits the ability of infected ...
