# Targeting Autophagy for Otoprotection: Translating Basic Mechanisms into Clinical Strategies

## TL;DR

This paper explores how autophagy, a cellular process, can be targeted to protect hearing and potentially lead to new treatments for hearing loss.

## Contribution

The paper introduces a dual-phase autophagy modulation strategy for otoprotection, offering a novel therapeutic framework.

## Key findings

- Autophagy has stage-specific and dual roles in sensorineural hearing loss.
- Mitophagy's context-dependent effects on cell survival are emphasized.
- A dual-phase strategy shows promise for guiding new drug development.

## Abstract

Sensorineural hearing loss (SNHL), the predominant form of global hearing impairment, stems from the irreversible loss of inner ear sensory cells and neurons. Since mammalian cochlea lacks regenerative capacity, cell death represents a final common pathway for diverse insults. Current therapies are merely compensatory, underscoring an urgent need for mechanistic, targeted interventions. Autophagy, a critical homeostatic process, plays complex and dynamic roles in the cochleae. This review synthesizes current evidence on its regulation, highlighting its stage-specific and dual roles in SNHL. We emphasize mitophagy and its context-dependent effects on cell survival. Critically, we discuss an emerging therapeutic paradigm: a dual-phase autophagy modulation strategy. This approach proposes enhancing cytoprotective autophagy in early stages to maintain homeostasis, while inhibiting excessive autophagic flux later to prevent catastrophic cell death. This precision-targeting framework holds significant promise for guiding novel drug development and future clinical translation, moving beyond symptomatic management towards transformative treatment.
