New Evidence: How Amino Acid Cysteine Combats Huntington’s Disease

Researchers at Johns Hopkins Medicine report they have identified a biochemical pathway linking oxidative stress and the amino acid cysteine in Huntington’s disease. The findings, described in last week’s issue of the Proceedings of the National Academy of of Sciences, provide a mechanism through which oxidative stress specifically damages nerve cells in Huntington’s disease, an inherited and fatal neurodegenerative disorder. read more

Genetically Engineered Mice Suggest New Model for How Alzheimer’s Disease Causes Dementia

Using a novel, newly developed mouse model that mimics the development of Alzheimer’s disease in humans, Johns Hopkins researchers say they have been able to determine that a one-two punch of major biological “insults” must occur in the brain to cause the dementia that is the hallmark of the disease. A description of their experiments is published online in the journal Nature Communications. read more
