Abstract

The PKR-like endoplasmic reticulum kinase (PERK) arm of the Integrated Stress Response (ISR) is implicated in neurodegenerative disease, although the regulators and consequences of PERK activation following neuronal injury are poorly understood. Here we show that PERK signaling is a component of the mouse MAP kinase neuronal stress response controlled by the Dual Leucine Zipper Kinase (DLK) and contributes to DLK-mediated neurodegeneration. We find that DLK-activating insults ranging from nerve injury to neurotrophin deprivation result in both c-Jun N-terminal Kinase (JNK) signaling and the PERK- and ISR-dependent upregulation of the Activating Transcription Factor 4 (ATF4). Disruption of PERK signaling delays neurodegeneration without reducing JNK signaling. Furthermore, DLK is both sufficient for PERK activation and necessary for engaging the ISR subsequent to JNK-mediated retrograde injury signaling. These findings identify DLK as a central regulator of not only JNK but also PERK stress signaling in neurons, with both pathways contributing to neurodegeneration.

  • Proinflammatory factors such as transforming growth factor ß (TGFß), interleukin-6 (IL6) and Wnt all activate NLK through MAPK-dependent signaling.

    “Proinflammatory factors such as transforming growth factor ß (TGFß), interleukin-6 (IL6) and Wnt all activate NLK through MAPK-dependent signaling (54).”

    From Nemo-like kinase disrupts nuclear import and drives TDP43 mislocalization in ALS (2025) · cites this paper as [54]

    The Results section, “DLK/JNK signaling is required for PERK activation” (page unavailable), concerns DLK, JNK and PERK signaling after neuronal injury. Searches for NLK and for TGFβ, IL-6 and Wnt found no passage in our copy addressing whether those factors activate NLK through MAPK-dependent signaling. (LLM, conf=0.77)

  • A pathway involving DLK, JNK, and PERK has previously been implicated in neuronal death.

    “A pathway involving DLK, JNK and PERK has previously been implicated in neuronal death (Ghosh et al., 2011; Huntwork-Rodriguez et al., 2013; Larhammar et al., 2017; Miller et al., 2009; Pozniak et al., 2013; Watkins et al., 2013; Welsbie et al., 2013), validating our approach.”

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
