‘Hello!’ from the team at Meadows & Wood Hearing Care Specialists. We’re excited to share some interesting research we came across that could, one day, transform the way we treat hearing loss, especially as we get older.
A recent study from the University of Southern California has uncovered how certain regenerative species, like fish and lizards, can naturally regenerate their hearing. The secret lies in two very special types of inner ear cells:
- Sensory cells: These detect sounds and send signals to the brain.
- Supporting cells: These maintain a healthy environment for sensory cells to function properly.
When the sensory cells of these regenerative species are damaged, they are replaced by supporting cells, which then transform into brand-new sensory cells helping to restore their hearing completely. Sadly, this isn’t something humans can do – yet!
Researchers have also discovered a set of DNA elements called ‘enhancers’, which play a crucial role in regenerating hearing. After an injury, these enhancers produce a protein called ATOH1, which activates genes needed to grow new sensory cells. When scientists removed these enhancers in zebrafish, the fish could no longer regenerate their hearing – proving just how powerful these tiny DNA elements are.
What does this mean for humans?
While this research is still in its early stages, it could one day lead to new therapies that can reactivate these enhancers in humans, helping us naturally restore our hearing cells.
