Lack of zinc can cause hearing loss by damaging important parts of inner ear cells in mice.

This study found that knocking out the Hars2 gene in mouse cochlear hair cells led to mitochondrial dysfunction and ROS stress, resulting in progressive hearing loss and differential effects on inner and outer hair cells.

In this phase 2a study of adults with alopecia areata, researchers observed that ritlecitinib treatment did not result in significant differences in brainstem auditory evoked potential changes or axonal swelling compared to placebo, suggesting the dog toxicity findings may not be clinically relevant in humans.

This study found that in SAMP8 mice, phenotypic changes in outer hair cells or the stria vascularis, possibly due to oxidative deficiencies, may predict variability in age-related hearing loss before outer hair cell loss occurs.

In this study, researchers found that after reducing GABAergic inhibition in rats' auditory midbrain, the brain quickly compensates by increasing local neurosteroid synthesis to maintain balance in neural circuits.
