NIH-funded research P01 program project

Investigating how aging affects auditory neurons at a cellular level

Official title: Proteomic Core D

Funded at University of Arizona · NIH-10910238 · Data updated 2026-11-12

This study is looking at how the tiny nerve cells in your ears change as you get older, which can help explain why some people experience hearing loss as they age.

Who could benefit from this research

Could help

Ideal candidates for this research are older adults experiencing hearing loss or those with age-related auditory changes.

Less likely to help

Patients with hearing loss due to non-aging related factors, such as noise exposure or genetic conditions, may not benefit from this research.

What this research studies

This research focuses on understanding the biochemical changes that occur in auditory neurons as they age, specifically targeting spiral ganglion neurons and cochlear nuclei neuron subtypes. By utilizing advanced liquid chromatography-mass spectrometry techniques, the study aims to analyze the proteomic profiles of these neurons at a single-cell resolution. This approach will help identify the specific alterations in protein composition that contribute to age-related hearing loss, providing insights into the underlying mechanisms of auditory neural aging.

Why it matters

Potential benefit: If successful, this research could lead to improved understanding and potential treatments for age-related hearing loss.

How similar studies have gone: Previous research has shown promise in using proteomic approaches to study cellular changes in various conditions, suggesting potential for success in this novel application.
