Protein EPS8 Associated with ALS in Older Americans Uncovered

Buzzline

A team of researchers from the University of Cologne has discovered that the protein EPS8 accumulates as individuals age and seems to instigate detrimental protein clustering within neurons, a characteristic of ALS and Huntington's disease. Studies on nematode worms revealed that increased EPS8 levels accelerated toxic protein aggregation and neurodegeneration, whereas diminishing EPS8 activity halted the buildup of aggregates and maintained neuronal health. These results were corroborated using human cell models for both conditions. Aging is recognized as a significant common risk factor for various neurodegenerative disorders. This research, published in Nature Aging, positions EPS8 as a promising target for future therapeutic interventions.

00:00Scientists may have found aging's hidden trigger for brain disease.

00:03It is a protein called EPS8.

00:06Researchers at the University of Cologne identified EPS8 as a molecular switch linking aging to neurodegenerative disease.

00:15EPS8 accumulates with age, and as it accumulates, it activates signaling pathways that promote toxic protein aggregation.

00:23In the researchers' words, higher EPS8 levels and increased activity in its signaling pathways promote pathological protein aggregation and neurodegeneration.

00:33That clumping is a hallmark of neurodegeneration.

00:36Two diseases sit at the center of this work.

00:40Amyotrophic lateral sclerosis, known as ALS, and Huntington's disease.

00:45The team ran its experiments in the nematode worm Canerhobditis elegans, the study's primary model organism,

00:53then they reduced EPS8 activity.

00:55Toxic protein aggregates no longer accumulated as readily.

00:59Neuronal function was preserved in the worm disease models.

01:02But worms are not people.

01:04So the team went further.

01:06Because EPS8 and its signaling pathways are conserved across evolution,

01:11the researchers validated the findings in human cell cultures.

01:15They used human cell models of both Huntington's disease and ALS.

01:20The results paralleled the worms.

01:23Reducing EPS8 prevented toxic protein accumulation in human cells, too.

01:28The work was led by Professor David Vilches at the CCAD Cluster of Excellence for Aging Research.

01:35First author, Dr. Sedeko Yunchiu, notes that age is the major common risk factor for different neurodegenerative diseases.

01:43Yet how exactly age-related changes contribute to these diseases remains largely unknown.

01:48Scientists still do not fully understand how increased EPS8 activity causes aggregation.

01:55They now see EPS8 and its signaling molecules as potential therapeutic targets.

02:00The study appears in Nature Aging.
