RNA Granules in Antiviral Innate Immunity: A Kaposi’s Sarcoma-Associated Herpesvirus Journey

Frontiers in Microbiology, 2022
RNA granules are cytoplasmic, non-membranous ribonucleoprotein compartments that form ubiquitously and are often referred to as foci for post-transcriptional gene regulation.

A hepatitis C virus cis-acting replication element forms a long-range RNA-RNA interaction with upstream RNA sequences in NS5B [PDF]

, 2008
The genome of hepatitis C virus (HCV) contains cis-acting replication elements (CREs) comprised of RNA stem-loop structures located in both the 5' and 3' non-coding regions (NCR), and in the NS5B coding sequence.

Stress Granules and Virus Replication [PDF]

Future Virology, 2011
Viruses are dependent on the cellular translation machinery for protein synthesis. Part of the innate immune response to infection is activation of the stress kinase PKR which phosphorylates the alpha subunit of the initiation factor eIF2. This results in inhibition of translation and is intended to block virus replication.

CpG Methylation Profiles of HIV-1 Proviral DNA in Individuals on ART

Viruses, 2021
The latent HIV-1 reservoir is comprised of stably integrated and intact proviruses with limited to no viral transcription. It has been proposed that latent infection may be maintained by methylation of pro-viral DNA.

Role of Lipids in Virus Replication [PDF]

Cold Spring Harbor Perspectives in Biology, 2011
Viruses intricately interact with and modulate cellular membranes at several stages of their replication, but much less is known about the role of viral lipids compared to proteins and nucleic acids. All animal viruses have to cross membranes for cell entry and exit, which occurs by membrane fusion (in enveloped viruses), by transient local disruption ...

Virus Replication

, 2017
The replication processes used by individual viruses is highly variable. However, all viruses must attach to a susceptible host cell, enter the cell, disassemble the virus particle (uncoating), replicate its own genetic material and express the associated proteins, assemble new virus particles, and escape from the infected cell (release).

Hepatitis C Virus Replication

Cold Spring Harbor Perspectives in Medicine, 2019
Replication and amplification of the viral genome is a key process for all viruses. For hepatitis C virus (HCV), a positive-strand RNA virus, amplification of the viral genome requires the synthesis of a negative-sense RNA template, which is in turn used for the production of new genomic RNA. This process is governed by numerous proteins, both host and

Phosphatidylinositol 4‐kinase as a target of pathogens—friend or foe?

FEBS Letters, EarlyView.
This graphical summary illustrates the roles of phosphatidylinositol 4‐kinases (PI4Ks). PI4Ks regulate key cellular processes and can be hijacked by pathogens, such as viruses, bacteria and parasites, to support their intracellular replication. Their dual role as essential host enzymes and pathogen cofactors makes them promising drug targets.

Hepatitis E Virus Replication [PDF]

Viruses, 2019
Hepatitis E virus (HEV) is a small quasi-enveloped, (+)-sense, single-stranded RNA virus belonging to the Hepeviridae family. There are at least 20 million HEV infections annually and 60,000 HEV-related deaths worldwide. HEV can cause up to 30% mortality in pregnant women and progress to liver cirrhosis in immunocompromised individuals and is ...

Tau acetylation at K331 has limited impact on tau pathology in vivo

FEBS Letters, EarlyView.
We mapped tau post‐translational modifications in humanized MAPT knock‐in mice and in amyloid‐bearing double knock‐in mice. Acetylation within the repeat domain, particularly around K331, showed modest increases under amyloid pathology. To test functional relevance, we generated MAPTK331Q knock‐in mice.
