Shigella flexnerimodulates stress granule composition and inhibits stress granule aggregation [PDF]
Invasion and multiplication of the facultative, cytosolic, enteropathogen Shigella flexneri within the colonic epithelial lining leads to an acute inflammatory response, fever and diarrhea. During the inflammatory process, infected cells are subjected to numerous stresses including heat, oxidative stress and genotoxic stress.

RNA self-assembly contributes to stress granule formation and defining the stress granule transcriptome [PDF]
Significance Stress granules, which are ubiquitous, non–membrane-bound assemblies of protein and RNA, form when translation initiation is inhibited, contribute to the regulation of gene expression, and are implicated in the pathologies of cancer and neurodegenerative disease. Understanding the mechanisms of stress

Who Regulates Whom? An Overview of RNA Granules and Viral Infections
After viral infection, host cells respond by mounting an anti-viral stress response in order to create a hostile atmosphere for viral replication, leading to the shut-off of mRNA translation (protein synthesis) and the assembly of RNA granules.

Dance with the Devil: Stress Granules and Signaling in Antiviral Responses
Cells have evolved highly specialized sentinels that detect viral infection and elicit an antiviral response. Among these, the stress-sensing protein kinase R, which is activated by double-stranded RNA, mediates suppression of the host translation ...

Viral modulation of stress granules
Following viral infection, the host responds by mounting a robust anti-viral response with the aim of creating an unfavorable environment for viral replication. As a countermeasure, viruses have elaborated mechanisms to subvert the host response in order to maintain viral protein synthesis and production.

Plant stress granules and mRNA processing bodies are distinct from heat stress granules [PDF]
SummarySimilar to the situation in mammalian cells and yeast, messenger ribonucleo protein (mRNP) homeostasis in plant cells depends on rapid transitions between three functional states, i.e. translated mRNPs in polysomes, stored mRNPs and mRNPs under degradation.

We reconstituted Synechocystis glycogen synthesis in vitro from purified enzymes and showed that two GlgA isoenzymes produce glycogen with different architectures: GlgA1 yields denser, highly branched glycogen, whereas GlgA2 synthesizes longer, less‐branched chains.

Nuclear stress granules are subnuclear compartments that form in response to heat shock and other stress stimuli. Although many components of nuclear stress granules have been identified, including HSF1 and pre-mRNA processing factors, their function remains a mystery. A paper in this issue describes the stress-induced transcriptional activation of one

CHARACTERIZING THE MODULATION OF STRESS GRANULE RESPONSES BY CORONAVIRUSES
Coronaviruses (CoVs) are a family of viruses that circulate in human populations causing mild common colds as well as severe and fatal respiratory disease.

Biomolecular condensates formed by fused in sarcoma (FUS) are dissolved by high ATP concentrations yet persist in cells. Using a reconstituted system, we demonstrate that valosin‐containing protein (VCP), an AAA+ ATPase, counteracts ATP‐driven dissolution of FUS condensates through its D2 ATPase activity.
