Scientists have identified a potential way to stimulate the regeneration of damaged retinal cells, raising new possibilities for future treatments of certain eye diseases.
The retina is the light-sensitive layer at the back of the eye that enables vision. Damage to its cells can contribute to serious conditions, including glaucoma and retinitis pigmentosa, which may lead to vision loss.
According to the study, researchers found that PROX1 can move from neighbouring retinal neurons into Müller glia, support cells within the retina. This transfer appears to restrict their ability to transform into cells that could help replace damaged retinal neurons.
In experiments involving mice, researchers disrupted the transfer of PROX1 and observed that Müller glia could reprogramme into retinal progenitor cells, which have the potential to develop into new retinal neurons.
The team also tested an antibody-based approach designed to block PROX1 transfer. The intervention promoted retinal cell regeneration and delayed vision loss in a mouse model of retinitis pigmentosa.
The findings could help advance research into regenerative treatments for retinal diseases, potentially offering a new direction beyond therapies that primarily aim to slow the progression of vision loss.
However, the results remain at the experimental stage. The research has not established that the approach can safely restore vision in humans, and further studies are needed before it can be considered a treatment option.
The discovery highlights the potential of regenerative medicine to explore new ways of repairing tissues once considered difficult to restore.
