Studying Alzheimer’s and Parkinson’s Disease using Pre-Formed Fibrils

Pre-formed fibrils are tools that allow scientists to mimic the pathophysiological effects of diseases such as Alzheimer's and Parkinson's disease in the brain. In this interview, Dr. Ariel Louwrier describes how the fibrils are created and explains how they are being used to develop new therapies.

			Do Antioxidants Benefit Patients with Alzheimer’s and Parkinson’s? A common pathological hallmark of many neurodegenerative diseases is the presence of oxidative stress caused by an accumulation of reactive oxygen species (ROS).

			New tool could speed up neuroscience research into pheromones Researchers at Worcester Polytechnic Institute have developed a tool to identify molecular receptors in worms that are involved in sensing pheromones related to mating, an advance that could speed up neuroscience research into pheromones by eliminating months of work.

	Protein linked with neurodegenerative diseases may help explore the aggressive behavior of gliomas A protein typically associated with neurodegenerative diseases like Alzheimer's might help scientists explore how gliomas, a type of cancerous brain tumor, become so aggressive.

	A protein found in ovarian cancer may contribute to neurodegeneration in Alzheimer's disease Houston Methodist scientists identified a protein found in ovarian cancer that may contribute to declining brain function and Alzheimer's disease, by combining computational methods and lab research.

	New molecular mechanism can reverse genetic defect responsible for Friedreich's ataxia Scientists at Tufts University have identified a molecular mechanism that could reverse the genetic defect responsible for Friedreich's ataxia, a neurodegenerative disease that leaves its victims with difficulty walking, a loss of sensation in the arms and legs and impaired speech caused by degeneration of nerve tissue in the spinal cord.

	Researchers uncover locomotor engine in the spinal cord Researchers at Karolinska Institutet in Sweden have revealed a new principle of organisation which explains how locomotion is coordinated in vertebrates akin to an engine with three gears. The results are published in the scientific journal Neuron.
