Parkinson's disease mechanism discovered

...o knew that accumulation of alpha-synuclein caused neurodegeneration in animal models of Parkinson's disease, but little was known about alpha-synuclein's normal cellular function or how it contributed to disease. One major problem facing researchers, Lindquist said, was that alpha-synuclein accumulation causes a rang...

'Sticky' mice lead to discovery of new cause of neurodegenerative disease

...al defect in protein synthesis could be behind the neurodegeneration they had observed in sticky mice. "There were a lot of candidate genes in the chromosomal region containing the sti mutation," she said, "and this gene was actually the last candidate gene we investigated. It seemed to us that a mutation in a gene...

Natural vitamin E tocotrienol reaches blood at protective levels

...n that needed to completely prevent stroke-related neurodegeneration as determined by earlier research. Conventional wisdom has suggested that TCT, if eaten, cannot be carried to organs because the protein known as tocopherol transfer protein (TTP), which delivers TCP throughout the body, doesn't transport TCT very...

"The new understanding of PanK2 activity and its location in the cell suggests a potential treatment strategy for PKAN," said Robe...
