A drug-like molecule called ISRIB, which activates the translation initiation factor eIF2B, antagonizes stress responses as diverse as protein misfolding and nutrient deprivation, and restores protein synthesis, enhancing memory.

Multiplexed mass spectrometry shows how the autophagy gene Atg16l1 regulates macrophage innate immunity against intracellular bacterial pathogens by modulating basal oxidative stress responses.

Immune activation in Drosophila macrophages during oxidative stress is regulated by DNA damage signaling, which controls proinflammatory cytokine release and the susceptibility of the fly to oxidative stress.
The hypoxia-inducible factor HIF drives transcription of the gene cyp-36A1, which encodes a cytochrome P450 enzyme that acts via a putative intercellular signal to regulate the nuclear receptor NHR-46 and consequently stress resistance and behavior.

Ribosome assembly is monitored to promote proteostatis through a system whereby unassembled ribosomal proteins lead to activation of heat shock factor 1 and inactivation of the RP gene activator Ifh1.
Human cells adapt to chronic mild stresses, such as slightly elevated temperature, by getting larger in a process that couples increased translation to increased cell size in an Hsp90-dependent manner.

DNL343, a brain-penetrant integrated stress response inhibitor, reduces neurodegeneration in mouse models and identifies biomarker candidates for assessing treatment responses in clinical settings.
