New insights on Parkinson's disease, blood vessel growth and cerebral malaria;

> A team at the University of Cambridge ID'd a critical threshold in the levels of a protein called alpha-synuclein, which "normally plays an important role in the smooth flow of chemical signals in the brain." Once the threshold is exceeded, they add, the proteins create a potentially toxic structure that could be a precursor to Parkinson's disease. Release

> Dr. Pipsa Saharinen, at the University of Helsinki, said: "What we have found in our studies on cells and in mice, is another angiopoietin-2 mediated cell pathway, which usually works to destabilize blood vessels, but which also could promote blood vessel growth. This pathway is not necessarily targeted by current angiopoietin-blocking therapies, and this could help explain why some of the trials have not produced as much benefit as we might have hoped."
