Keeping proteins healthy inside nerve fibers (axons)
Defining proteostasis networks in axon segments
This project looks at how segments of nerve fibers prevent proteins from clumping to help people with Alzheimer’s and other neurodegenerative diseases.

What this research studies
From my perspective as someone affected by dementia, the team is studying the tiny machinery inside long nerve projections called axons that makes and disposes of proteins. They will test how well isolated axon segments resist protein misfolding and aggregation and identify the cellular systems that break down or remove damaged proteins. The work uses molecular and cellular lab experiments with nerve cells and axon preparations to watch how proteins are handled locally in axons. The goal is to close gaps in basic knowledge about why axons become vulnerable with age and disease.
Who could benefit from this research
Good fit: People living with Alzheimer’s disease or related neurodegenerative conditions and their caregivers who want research on nerve-cell health would be most interested in the long-term implications of this work.
Not a fit: Because this is laboratory research into basic mechanisms rather than a clinical treatment trial, patients seeking an immediate new therapy are unlikely to benefit directly right now.
Why it matters
Potential benefit: If successful, this work could point to new ways to protect axons and slow or prevent the loss of brain connections in Alzheimer’s and related diseases.
How similar studies have performed: Previous lab studies have shown that improving protein quality control can protect neurons in model systems, but focusing specifically on how axon segments handle misfolded proteins is a relatively new and specialized area.
