Injury to axon can stop neuron growth, says new study Injury to axon can stop neuron growth, says new study Last Updated: Tue, Dec 15th, 2020, 08:14:02hrs California [US], December 15 (ANI): A recent study led by researchers from the University of California - San Diego, has claimed that injury to axons can lead to severe neurodegenerative conditions and also suggested ways to protect it for encouraging neuron growth. A paper published in Proceedings of the National Academy of Sciences of the United States of America (PNAS), has discovered the injury to that axons- the long, slender projections that conduct electrical impulses from one nerve cell to another, facilitating cellular communications often leads to many neurodegenerative conditions like glaucoma and Alzheimer.
