Researchers at the University of Toronto Scarborough (UTSC) used an innovative technique to examine chemical interactions that are implicated in Parkinson's Disease. The work details how a protein called alpha-synuclein interacting with the brain chemical dopamine can lead to protein misfolding and neuronal death. Parkinson's Disease is a neurodegenerative disease which results in loss of motor control and cognitive function. Although the cause isn't known precisely, the disease...

Two studies by neurological researchers at Rush University Medical Center suggest that, in the future, colonic tissue obtained during either colonoscopy or flexible sigmoidoscopy may be used to predict who will develop Parkinson's disease, a neurodegenerative disorder of aging that that leads to progressive deterioration of motor function due to loss of neurons in the brain that produce dopamine, a neurotransmitter essential to executing movement. Currently, Parkinson's disease afflicts...

Suggests way disorder progresses over time in humans Last year, researchers from the Perelman School of Medicine at the University of Pennsylvania found that small amounts of a misfolded brain protein can be taken up by healthy neurons, replicating within them to cause neurodegeneration. The protein, alpha-synuclein (a-syn), is commonly found in the brain, but forms characteristic clumps called Lewy bodies, in neurons of patients with Parkinson's disease (PD) and other neurodegenerative...

Injection of a small amount of clumped protein triggers a cascade of events leading to a Parkinson's-like disease in mice, according to an article published online this week in the Journal of Experimental Medicine. Progressive accumulation of clumps of the protein alpha-synuclein in the brains of patients with Parkinson's disease coincides with the onset of motor dysfunction. However, whether these clumps are sufficient to trigger neurodegeneration, and how these clumps spread throughout...

Curcumin, a compound found in the spice turmeric, is proving effective at preventing clumping of a protein involved in Parkinson´s disease, says a Michigan State University researcher. A team of researchers led by Basir Ahmad, an MSU postdoctoral researcher, demonstrated earlier this year that slow-wriggling alpha-synuclein proteins are the cause of clumping, or aggregation, which is the first step of diseases such as Parkinson´s. A new study led by Ahmad, which appears in the...

Treatments for Parkinson's disease, estimated to affect 1 million Americans, have yet to prove effective in slowing the progression of the debilitating disease. However, University of Alabama researchers have identified how a specific gene protects dopamine-producing neurons from dying in both animal models and in cultures of human neurons, according to a scientific article publishing in the Feb. 8 edition of The Journal of Neuroscience. This increased understanding of the gene's...

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. Now, a group of scientists from Sweden has found a way to reliably replicate α-synuclein aggregation on cell membranes to investigate how different forms of α-synuclein...

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.   A team of researchers led by Basir Ahmad, a postdoctoral researcher at Michigan State University, has demonstrated that slow-wriggling alpha-synuclein proteins are the cause of aggregation, or clumping together, which is the first step of Parkinson´s. The results are published in the current issue of the Proceedings of the...


Word of the Day
penuche
  • A fudgelike confection of brown sugar, cream or milk, and chopped nuts.
'Penuche' is a variant of 'panocha,' a coarse grade of sugar made in Mexico. 'Panocha' probably comes from the Spanish 'panoja, panocha,' ear of grain.
