The Development Of Parkinson's Cells Visualized By Researchers
In the US alone, at least 500,000 people suffer from Parkinson's disease, a neurological disorder that affects a person's ability to control his or her movement. New technology from the University of Bonn in Germany lets researchers observe the development of the brain cells responsible for the disease...

Prion-Like Protein Plays A Key Role In Storing Long-Term Memories
Memories in our brains are maintained by connections between neurons called "synapses"...

New Standard For Vitamin D Testing To Ensure Accurate Test Results
At a time of increasing concern about low vitamin D levels in the world's population and increased use of blood tests for the vitamin, scientists are reporting development of a much-needed reference material to assure that measurements of vitamin D levels are accurate. The report appears in ACS' journal Analytical Chemistry...

Protein Identified That Contributes To Symptoms Of Parkinson's Disease
Scientists at the Gladstone Institutes, an independent and nonprofit biomedical-research organization, have identified a protein that exacerbates symptoms of Parkinson's disease - a discovery that could one day lead to new treatments for people who suffer from this devastating neurodegenerative illness...

First Step In Strategy For Cell Replacement Therapy In Parkinson's Disease
Induced pluripotent stem cells (iPSC) are a promising avenue for cell replacement therapy in neurologic diseases. For example, mouse and human iPSCs have been used to generate dopaminergic (DA) neurons that improve symptoms in rat Parkinson's disease models...

Inability To Express Emotion May Be An Early Symptom Of Parkinson's Disease
Alexithymia, a person's state of deficiency in understanding, processing, or describing emotions, has been strongly linked to depression in both clinical and general populations, and even though symptoms of alexithymia and depression can be partially overlapping, they are not all related to depressive symptoms and therefore highlight the relative independence of the two disorders...

How Alpha-Synuclein Interacts With Cell Membranes In Parkinson's Disease
The accumulation of α-synuclein, a small, negatively charged protein, in neural cells, is one of the hallmarks of Parkinson's disease. It has been suggested that oligomeric α-synuclein causes membranes to become permeable, or to form channels on the outer cell membrane...

Solving The Parkinson's Conundrum: Biologists A Step Closer
Research by a team in the University's Department of Biology found evidence that movement disorders, including tremor and slowness of movement (bradykinesia), associated with Parkinson's disease (PD) may be due to a defect in energy production in the nervous system. The advance may help to identify young adults who may be susceptible to the disease...

Researchers Identify Path To Treat Parkinson's Disease At Its Inception
Imagine if doctors could spot Parkinson's disease at its inception and treat the protein that triggers it before the disease can sicken the patient...

Cell 'Battery' Found To Play Central Role In Neurodegenerative Disease
A devastating neurodegenerative disease that first appears in toddlers just as they are beginning to walk has been traced to defects in mitochondria, the 'batteries' or energy-producing power plants of cells...

How A Motor Protein 'Steps Out'
Just like people, some proteins have characteristic ways of "walking," which (also like human gaits) are not so easy to describe...

Iron Intake In Teen Years Can Impact Brain In Later Life
Iron is a popular topic in health news. Doctors prescribe it for medical reasons, and it's available over the counter as a dietary supplement. And while it's known that too little iron can result in cognitive problems, it's also known that too much promotes neurodegenerative diseases...

"ORMOSIL" Nanoparticles Hold Promise As A Potential Vehicle For Drug Delivery
In the images of fruit flies, clusters of neurons are all lit up, forming a brightly glowing network of highways within the brain. It's exactly what University at Buffalo researcher Shermali Gunawardena was hoping to see: It meant that ORMOSIL, a novel class of nanoparticles, had successfully penetrated the insects' brains...

Lewy Bodies Not Found To Be The Primary Cause Of Cell Death In Parkinson's Disease
The pathology of Parkinson's disease is characterized by a loss of dopamine-producing neurons in the pars compacta of the substantia nigra (SN), an area of the brain associated with motor control, along with the development of α-synuclein (αS) protein in the form of Lewy bodies (LB) in the neurons that survive...

Studies Identify Promising Genes And Small Molecules To Use Against Devastating Diseases
Two related studies from Northwestern University offer new strategies for tackling the challenges of preventing and treating diseases of protein folding, such as Alzheimer's, Parkinson's and Huntington's diseases, amyotrophic lateral sclerosis (ALS), cancer, cystic fibrosis and type 2 diabetes. To do its job properly within the cell, a protein first must fold itself into the proper shape...
