KIF5A binds RNA to orchestrate synaptic mRNA localization and stress granules in ALS.
bioRxiv : the preprint server for biology · 2025
Neuronal health depends on the precise transport and local translation of mRNAs to maintain synaptic function across highly polarized cellular architecture. While kinesin motor proteins are known to mediate mRNA transport, the specificity and direct involvement of individual kinesins as …

Investigational eIF2B activator DNL343 modulates the integrated stress response in preclinical models of TDP-43 pathology and individuals with ALS in a randomized clinical trial.
Nature communications · 2025 · 16(1): 7690
Neuronal TDP-43 aggregates are a hallmark ALS pathology. The integrated stress response (ISR) occurs downstream of TDP-43 pathology and may promote neurodegeneration. Here we demonstrate that a CNS penetrant small molecule eIF2B activator inhibits the ISR in cellular models of …

RNA triggers chronic stress during neuronal aging.
bioRxiv : the preprint server for biology · 2025
Neurodegenerative diseases are linked with dysregulation of the integrated stress response (ISR), which coordinates cellular homeostasis during and after stress events. Cellular stress can arise from several sources, but there is significant disagreement about which stress might contribute to aging …

Huntington's disease mice and human brain tissue exhibit increased G3BP1 granules and TDP43 mislocalization.
The Journal of clinical investigation · 2021 · 131(12)
Chronic cellular stress associated with neurodegenerative disease can result in the persistence of stress granule (SG) structures, membraneless organelles that form in response to cellular stress. In Huntington's disease (HD), chronic expression of mutant huntingtin generates various forms of cellular …
