- Summary
In a February 2026 issue of Science, researchers report a new mechanism that terminates the integrated stress response (ISR). The study identifies a previously uncharacterized protein complex that rapidly dephosphorylates eIF2α, the key regulator of ISR activation. By restoring eIF2α to its inactive state, the complex shuts down the stress‑induced translational block and allows cells to resume normal protein synthesis. The authors demonstrate that manipulating this pathway can rescue cell viability in models of neurodegeneration and metabolic disease, suggesting potential therapeutic targets for conditions linked to chronic ISR activation.
