 Alzheimer's neutralised in human brain cells for first time
A gene associated with Alzheimer's has been neutralised in human brain cells for the first time, California-based researchers have claimed. Scientists "turned off" a protein associated with the apoE4 gene, which damages nerve cells, leading to dementia. Having one copy of the gene doubles the risk of Alzheimer's, whereas two copies increase the risk by 12 times, noted researchers.
