abstract = {Aging is the most important risk factor for
neurodegenerative diseases associated with pathological
protein aggregation such as Alzheimer's disease. Although
aging is an important player, it remains unknown which
molecular changes are relevant for disease initiation.
Recently, it has become apparent that widespread protein
aggregation is a common feature of aging. Indeed, several
studies demonstrate that 100s of proteins become highly
insoluble with age, in the absence of obvious disease
processes. Yet it remains unclear how these misfolded
proteins aggregating with age affect neurodegenerative
diseases. Importantly, several of these aggregation-prone
proteins are found as minor components in disease-associated
hallmark aggregates such as amyloid-β plaques or
neurofibrillary tangles. This co-localization raises the
possibility that age-dependent protein aggregation directly
contributes to pathological aggregation. Here, we show for
the first time that highly insoluble proteins from aged
Caenorhabditis elegans or aged mouse brains, but not from
young individuals, can initiate amyloid-β aggregation in
vitro. We tested the seeding potential at four different
ages across the adult lifespan of C. elegans. Significantly,
protein aggregates formed during the early stages of aging
did not act as seeds for amyloid-β aggregation. Instead, we
found that changes in protein aggregation occurring during
middle-age initiated amyloid-β aggregation. Mass
spectrometry analysis revealed several late-aggregating
proteins that were previously identified as minor components
of amyloid-β plaques and neurofibrillary tangles such as
14-3-3, Ubiquitin-like modifier-activating enzyme 1 and
Lamin A/C, highlighting these as strong candidates for
cross-seeding. Overall, we demonstrate that widespread
protein misfolding and aggregation with age could be
critical for the initiation of pathogenesis, and thus should
be targeted by therapeutic strategies to alleviate
neurodegenerative diseases.},
