🧪 Overview

Age-dependent Nup358 degradation enables pathogenic protein import into the nucleus. Decreased Nup358 expression with aging leads to defective nuclear pore complex gating. This allows abnormal accumulation of disease proteins within the nucleoplasm where they can interact with splicing machinery and transcriptional regulators.

⚖️ Evidence

⚖️ Evidence Matrix3 supports3 contradicts
Supports
Nup358 reduces with age in human brain
PMID:29107213
Supports
α-Synuclein localizes to nuclei in PD neurons

Contradicts
α-Synuclein nuclear localization observed in <10% of neurons—not widespread
PMID:25877302
Contradicts
TDP-43 pathology is cytoplasmic accumulation (loss of nuclear function), opposite to hypothesis
PMID:29107321
Contradicts
Nuclear accumulation may be protective—sequestering toxic species from synapses
