Analysis of the Replication Mechanisms of the Human Papillomavirus Genomes

open access: yesFrontiers in Microbiology, 2021
The life-cycle of human papillomaviruses (HPVs) includes three distinct phases of the viral genome replication. First, the viral genome is amplified in the infected cells, and this amplification is often accompanied by the oligomerization of the viral ...

Antiviral and antioxidant activity of a hydroalcoholic extract from Humulus lupulus L. [PDF]

open access: yes, 2018
A hydroalcoholic extract from female inflorescences of Humulus lupulus L. (HOP extract) was evaluated for its anti-influenza activity. The ability of the extract to interfere with different phases of viral replication was assessed, as well as its effect ...

Intranuclear Positions of HIV-1 Proviruses Are Dynamic and Do Not Correlate with Transcriptional Activity

open access: yesmBio, 2022
The relationship between spatiotemporal distribution of HIV-1 proviruses and their transcriptional activity is not well understood. To elucidate the intranuclear positions of transcriptionally active HIV-1 proviruses, we utilized an RNA fluorescence in ...

A novel mechanism underlying the innate immune response induction upon viral-dependent replication of host cell mRNA: A mistake of +sRNA viruses' replicases [PDF]

open access: yes, 2017
Viruses are lifeless particles designed for setting virus-host interactome assuring a new generation of virions for dissemination. This interactome generates a pressure on host organisms evolving mechanisms to neutralize viral infection, which places the

Passaging of a Newcastle disease virus pigeon variant in chickens results in selection of viruses with mutations in the polymerase complex enhancing virus replication and virulence [PDF]

open access: yes, 2010
Some Newcastle disease virus (NDV) variants isolated from pigeons (pigeon paramyxovirus type 1; PPMV-1) do not show their full virulence potential for domestic chickens but may become virulent upon spread in these animals.

Zika virus promotes CCN1 expression via the CaMKIIα-CREB pathway in astrocytes. [PDF]

open access: yes, 2020
Zika virus (ZIKV) infection in the human central nervous system (CNS) causes Guillain-Barre syndrome, cerebellum deformity, and other diseases. Astrocytes are immune response cells in the CNS and an important component of the blood-brain barrier ...

Development of Lentiviral Vectors for HIV-1 Gene Therapy with Vif-Resistant APOBEC3G

open access: yesMolecular Therapy: Nucleic Acids, 2019
Strategies to control HIV-1 replication without antiviral therapy are needed to achieve a functional cure. To exploit the innate antiviral function of restriction factor cytidine deaminase APOBEC3G (A3G), we developed self-activating lentiviral vectors ...

The KSHV ORF20 Protein Interacts with the Viral Processivity Factor ORF59 and Promotes Viral Reactivation

open access: yesMicrobiology Spectrum, 2021
Upon Kaposi’s Sarcoma-associated herpesvirus (KSHV) lytic reactivation, rapid and widespread amplification of viral DNA (vDNA) triggers significant nuclear reorganization.

Myxoma virus protein M029 is a dual function immunomodulator that inhibits PKR and also conscripts RHA/DHX9 to promote expanded host tropism and viral replication. [PDF]

open access: yes, 2013
Myxoma virus (MYXV)-encoded protein M029 is a member of the poxvirus E3 family of dsRNA-binding proteins that antagonize the cellular interferon signaling pathways.

The activation of KSHV lytic cycle blocks autophagy in PEL cells [PDF]

open access: yes, 2015
This study confirms that autophagy is activated concomitantly with KSHV lytic cycle induction, and that autophagy inhibition by BECN1 knockdown reduces viral lytic gene expression.
