Most of us usually associate fish as a delicious food item. However, based on a new research, scientists are now saying that a certain type of fish may hold the key for the treatment of blindness among humans. Scientists have discovered that Zebra fish has the ability to regrow its retina, something that may help medical science to discover a method to treat blindness among humans.
During research, scientists found that when the fish is in the process of repairing its retina, the levels of GABA (gamma aminobutyric acid) drop significantly. GABA is widely known for its role in calming nervous activity. Scientists believe that if they can do something similar in humans, i.e. block the chemical GABA, it could help treat blindness in humans. Such a treatment would be beneficial for AMD (age related macular degeneration), which is the most common cause of blindness and retinitis pigmentosa.
Scientists are hopeful since the eyes of fish are quite similar to that of mammals, especially the retina. Speaking on the findings of the new research, James Patton, Professor at Vanderbilt University, in Tennessee, US said, “Our theory is that a drop in GABA concentration is the trigger for regeneration. If we are correct, then it might be possible to stimulate human retinas to repair themselves by treating them with a GABA inhibitor.”
