Genes that helps prevent brain disease

18-May-2018

Scientists know that faulty proteins can cause harmful deposits or "aggregates" in neurological disorders such as Alzheimer's and Parkinson's disease. Although the causes of these protein deposits remain a mystery, it is known that abnormal aggregates can result when cells fail to transmit proper ...
