Porcine Respiratory and Reproductive Syndrome Virus Variants, Vietnam and China, 2007

Emerging Infectious Diseases, 2008
We characterized isolates from porcine respiratory and reproductive syndrome virus epidemics in Vietnam and China in 2007. These isolates showed ≈99% identity at the genomic level. Genetic analysis indicated that they share a discontinuous deletion of 30

The alphaviruses: gene expression, replication, and evolution [PDF]

, 1994
The alphaviruses are a genus of 26 enveloped viruses that cause disease in humans and domestic animals. Mosquitoes or other hematophagous arthropods serve as vectors for these viruses.

Hepatitis C virus NS5A targets the nucleosome assembly protein NAP1L1 to control the innate cellular response [PDF]

, 2017
Hepatitis C virus (HCV) is a single-stranded positive-sense RNA hepatotropic virus. Despite cellular defenses, HCV is able to replicate in hepatocytes and to establish a chronic infection that could lead to severe complications and hepatocellular ...

Innate immunity shapes the persistent transmission of plant viruses by insect vectors

New Plant Protection, EarlyView.
In this review, we focus on two key aspects of the virus–vector interplay: (1) persistently transmitted viruses utilize host factors to overcome transmission barriers; and (2) molecular recognition activates antiviral immunity and subsequent viral counter‐defense. Understanding these interactions offers critical insights for developing novel strategies

Expression Profile and Localization of SARS-CoV-2 Nonstructural Replicase Proteins in Infected Cells

Microbiology Spectrum, 2022
The intracellular localization of SARS-CoV-2 replicase nonstructural proteins (nsp) during infection has not been fully elucidated. In this study, we systematically analyzed the expression and subcellular localization of 11 distinct viral nsp and dsRNA over time in SARS-CoV-2-infected cells by using individual antibody against these replicase proteins.

Endoplasmic reticulum stress and the unfolded protein response in lung diseases: molecular pathways and therapeutic interventions

The Journal of Pathology, EarlyView.
Abstract Endoplasmic reticulum stress (ERS) occurs when the protein‐folding capacity of the endoplasmic reticulum (ER) is overwhelmed, triggering the unfolded protein response (UPR) to restore homeostasis. However, severe or persistent ERS can shift the UPR toward pro‐inflammatory, apoptotic, and fibrotic signaling, thereby exacerbating tissue injury ...

Respiratory syncytial virus nonstructural protein 2 specifically inhibits type I interferon signal transduction

Virology, 2006
Human respiratory syncytial virus (RSV) inhibits type I interferon-induced gene expression by decreasing expression of signal transducer and activator of transcription (Stat)2. To identify the RSV protein that mediates effects on Stat2, airway epithelial cells were infected with vaccinia virus vectors that express single RSV proteins. Expression of RSV

Iflaviruses in arthropods: when small is mighty

Insect Science, EarlyView.
Many arthropod species harbor iflaviruses, which often cause covert (asymptomatic) infections, but may still affect host fitness. We review the impact of iflaviruses on arthropod fitness, immunity, behaviour as well as the iflavirus’ host range, transmission, tissue tropism and the interactions with other microorganisms within arthropods.

Plasma metabolomics and gene regulatory networks analysis reveal the role of nonstructural SARS-CoV-2 viral proteins in metabolic dysregulation in COVID-19 patients

Scientific Reports, 2022
Metabolomic analysis of blood plasma samples from COVID-19 patients is a promising approach allowing for the evaluation of disease progression. We performed the metabolomic analysis of plasma samples of 30 COVID-19 patients and the 19 controls using the ...

The interferon-induced exonuclease ISG20 exerts antiviral activity through upregulation of type I interferon response proteins [PDF]

, 2018
The host immune responses to infection lead to the production of type I interferon (IFN), and the upregulation of interferon-stimulated genes (ISGs) reduces virus replication and virus dissemination within a host.
