Clinical and experimental evidence suggests however that alpha - synuclein — or abnormal forms of it — could «jump» from one neuron to another and thus spread between anatomically interconnected regions.

«Our study shows that alpha - synuclein is able to travel quite far through the body, passing from one neuron to another and using long nerve fibers as conduits,» Di Monte says.

Until now, scientists haven't thought this build - up was important to the disease process because it looked different from the types of protein accumulations — such as tau, amyloid and alpha synuclein — that are clearly toxic and always found in patients with Alzheimer's, Parkinson's and some forms of dementia.

For example, α - synuclein, a protein that has been linked to Parkinson disease and other neurodegenerative disorders, helps assemble the fusion apparatus and protects animals from age - related neurological problems.

In research published in this week's issue of the journal Science, a team from Whitehead Institute for Biomedical Research used common baker's yeast as a living test tube to show how just a small amount of a Parkinson's - related neuronal protein called alpha - synuclein (aSyn) can convince neighboring proteins to abandon their normal shape and form these deadly clusters.

PRX002: Targeting C - Truncated Alpha - Synuclein When we last reported news from Prothena Corp PLC, their cofounder and CEO Dr. Dale Schenk had recently presented the results of studies using their AS - targeting antibodies at SENS Research Foundation's Rejuvenation Biotechnology 2014 conference.

In the fall of 2012, their group demonstrated that misfolded versions of α - synuclein, the protein implicated in Parkinson's disease, can be transmitted from cell to cell in mouse models, adding weight to a hypothesis that a common mechanism of neurodegenerative disorders could involve the passage of misfolded proteins through the central nervous system.
