Why some human brains age faster
Molecular mechanisms of aging and accelerated aging in the human brain
['FUNDING_R01'] · BETH ISRAEL DEACONESS MEDICAL CENTER · NIH-11468158
This project looks at genes and tiny RNA molecules in brain samples to find what causes normal and faster-than-normal brain aging, including links to respiratory infections like COVID-19.

What this research studies
Researchers will analyze gene and microRNA activity in aged human brain samples and in models of accelerated brain aging to find molecular signatures tied to decline. They will compare young and old samples and samples from people exposed to respiratory viruses (including COVID-19) to spot changes that speed up brain aging. Work will combine data from mouse studies, patient RNA sequencing, and laboratory experiments to identify regulators that could be drug targets. The goal is to point to specific genes or microRNAs that can be tested in future studies to slow or reverse cognitive aging.
Who could benefit from this research
Good fit: Ideal candidates would be older adults or people with cognitive changes and those with a history of respiratory viral infections (including COVID-19) who can provide clinical information or biospecimens.
Not a fit: People without signs of brain aging or those seeking an immediate treatment benefit are unlikely to gain direct benefit from this basic and translational research.
Why it matters
Potential benefit: Could point to specific molecular targets that lead to new treatments to slow or reverse brain aging and reduce post-infection cognitive decline.
How similar studies have performed: Previous mouse work and RNA sequencing from COVID-19 patients have revealed aging-like molecular signatures, but turning these signals into effective therapies is still largely unproven.
