Alzheimer's disease is transmitted from neuron to neuron

Scientists from the Van Andel Research Institute (VARI) and Lund University, Sweden, have published a study that clarifies how Parkinson’s disease spreads throughout the brain. Experiments in a rat model of the neurodegenerative disease reveal a process that has previously been used to explain mad cow disease: the migration of misfolded proteins from diseased to healthy cells. This model has never been demonstrated so clearly in a living organism, and the scientists’ breakthrough brings us one step closer to drugs that can actively intervene in Parkinson’s disease.
