Overexpression or Activation of Potassium Channel TASK-3 Protects Retinal Ganglion Cells and Restores Visual Function in Optic Nerve Crush

Key Points

• To investigate the role of TASK-3 in protecting retinal ganglion cells (RGCs) and restoring visual function following optic nerve injury.
• Utilized pharmacological agents to activate or upregulate TASK-3.
• Assessed retinal ganglion cell survival and visual function post-optic nerve crush.
• Evaluated outcomes through functional tests and cellular analysis.
• TASK-3 activation led to increased survival of retinal ganglion cells.
• Visual function was significantly restored in models after optic nerve injury.
• Pharmacological interventions showed a clear correlation with enhanced recovery outcomes.
