How aging nerve cells and inflammation may drive Alzheimer’s
Neuronal senescence and inflammation in Alzheimer's disease
Using small skin samples from people with and without Alzheimer’s, researchers will make aged brain cells in the lab to look at signs of cellular aging and inflammation that might cause memory loss.

What this research studies
Scientists will take small skin samples (fibroblasts) and convert them directly into neurons that keep the donor’s age-related features. They will compare neurons from people with Alzheimer’s to neurons from healthy older adults to find cells showing signs of senescence (cellular aging) and inflammation. The team will read gene activity and chromatin accessibility (RNA-Seq and ATAC-Seq) in senescent versus non-senescent cells to pinpoint molecular differences. This work aims to reveal specific age-linked changes in neurons that could explain why older brains become vulnerable to Alzheimer’s.
Who could benefit from this research
Good fit: Ideal candidates are older adults with sporadic Alzheimer’s disease and age-matched volunteers who can provide a small skin biopsy or fibroblast sample for lab work.
Not a fit: People who cannot or do not want to donate tissue, or those with early-onset genetic Alzheimer’s focused on different causes, are unlikely to see direct benefit from this lab-based work.
Why it matters
Potential benefit: If successful, this work could point to new targets to slow or prevent Alzheimer’s by addressing age-related cell changes and inflammation.
How similar studies have performed: Using induced neurons that retain donor age is a relatively new approach with promising early results for revealing disease changes, but it has not yet produced direct treatments for patients.
