Stress Granules in the Viral Replication Cycle [PDF]
Viruses, 2011 As intracellular parasites, viruses require a host cell in order to replicate. However, they face a series of cellular responses against infection. One of these responses is the activation of the double-stranded RNA (dsRNA)-activated protein kinase R (PKR). PKR phosphorylates the α subunit of eukaryotic translation initiation factor 2 (eIF2α), which in

Crystal structure of the catalytic domain of HIV-1 restriction factor APOBEC3G in complex with ssDNA
Nature Communications, 2018 APOBEC3G (A3G) is a single-stranded DNA (ssDNA) cytidine deaminase that restricts HIV-1. Here the authors provide molecular insights into A3G substrate recognition by determining the 1.86 Å resolution crystal structure of its catalytic domain bound to ...

UGGT1 enhances enterovirus 71 pathogenicity by promoting viral RNA synthesis and viral replication. [PDF]
PLoS Pathogens, 2017 Positive-strand RNA virus infections can induce the stress-related unfolded protein response (UPR) in host cells. This study found that enterovirus A71 (EVA71) utilizes host UDP-glucose glycoprotein glucosyltransferase 1 (UGGT1), a key endoplasmic ...

Zika NS1–induced ER remodeling is essential for viral replication
Journal of Cell Biology, 2019 Zika virus induces the formation of vesicles from ER membrane that form viral replication factories in the ER lumen. Ci et al. show that the Zika NS1 protein plays a key role in this remodeling of the ER as the insertion of the hydrophobic regions of NS1

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

Opportunistic infection as a cause of transient viremia in chronically infected HIV patients under treatment with HAART [PDF]
Bulletin of Mathematical Biology (67) 1227-1251 (2005), 2004 When highly active antiretroviral therapy is administered for long periods of time to HIV-1 infected patients, most patients achieve viral loads that are ``undetectable'' by standard assay (i.e., HIV-1 RNA $ < 50$ copies/ml). Yet despite exhibiting sustained viral loads below the level of detection, a number of these patients experience unexplained ...

Mutations in the C-terminus of HBoV NS1 affect the function of NP1
Scientific Reports, 2017 Human bocavirus 1 (HBoV1) is an autonomous parvovirus in the Bocaparvovirus genus. The multifunctional nuclear protein NP1 is involved in viral replication.
