A molecule capable of regenerating damaged nerve fibers may offer hope for glaucoma patients
Phoebe Harkin | | Quick Read
Retinal ganglion cells extend their axons (nerve fibers) to the brain via the optic nerve to process visual information. When these axons are injured, the damage is usually irreversible – but it may be possible to stimulate regeneration with the help of the adaptor molecule protrudin. Researchers at the University of Cambridge used a cell culture system to grow brain cells in a dish, then injured the axons and analyzed the response using live-cell microscopy. Their findings? Increasing the amount or activity of protrudin in these cells vastly increased their ability to regenerate.
