Scientists may have found aging’s hidden trigger for brain disease
Scientists have identified that the protein EPS8 accumulates with age and triggers signaling pathways that lead to toxic protein buildup in the brain. Reducing the activity of this protein in worm models helped prevent neurodegeneration, offering a potential target for treating diseases like ALS and Huntington's.
Why it matters
Linking aging-related molecular changes to specific neurodegenerative diseases could lead to new therapeutic strategies for age-associated brain disorders.
Aging is the strongest known risk factor for neurodegenerative diseases, yet researchers still do not fully understand which molecular changes associated with getting older cause these conditions to develop.
Scientists have now identified a protein pathway that may help connect aging with the harmful protein buildup seen in disorders such as Huntington's disease and amyotrophic lateral sclerosis (ALS).
Searching for the Link Between Aging and Brain Disease
A research team led by Professor Dr. David Vilchez at the CECAD Cluster of Excellence for Aging Research investigated this connection using the small nematode worm Caenorhabditis elegans . The researchers examined a signaling pathway that becomes increasingly active with age and contributes to the accumulation of abnormal proteins.
Their study, titled "The aging factor EPS8 induces disease-related protein aggregation through RAC signaling hyperactivation," was published in Nature Aging .
