Survival mode that protects cells when oxygen is low also slows aging

A biochemical pathway that helps keep cells alive when oxygen is low also plays a role in longevity and resistance against some diseases of old age, according to a report to be published April 16 in the journal Science.

Neurodegenerative diseases target healthy brain's intrinsic networks

New research suggests that neurodegenerative diseases are neither diffuse nor random but specifically target large-scale functional networks in the human brain.

Neurodegeneration study reveals targets of destruction

Scientists are reporting the strongest evidence to date that neurodegenerative diseases target and progress along distinct neural networks that normally support healthy brain function.

New common pathway in neurodegenerative disease is a possible door to a point of no return

A just-out study suggests that what keeps chronic nervous system diseases such as Alzheimer's, Huntington's and ALS going - until they overcome the internal protective mechanisms a body can throw at them - may largely come down to poor conversational skills.

Alzheimer's disease linked to mitochondrial damage

Investigators at the Burnham Institute for Medical Research (Burnham) have demonstrated that attacks on the mitochondrial protein Drp1 by the free radical nitric oxide-which causes a chemical reaction called S-nitrosylation-mediates neurodegeneration associated with Alzheimer's disease.

New brain mapping capabilities come to desktops of scientists worldwide

Mapping the billions of connections in the brain is a grand challenge in neuroscience.

Researchers find direct link between oxidative stress and inflammatory signals in the blood

The finding could lead to improved strategies for preventing several diseases by including antioxidants in the diet and for reducing the impact of inflammation in critically ill patients by adding cysteine to intravenous or tube feeding.

Discovery of mechanism of neurodegeneration in Alzheimer's disease

Tiny, toxic protein particles severely disrupt neurotransmission and inhibit delivery of key proteins in Alzheimer's disease, two separate studies by Marine Biological Laboratory (MBL) researchers have found.

Merck Serono launches strategic venture capital fund

Merck Serono, a division of Merck KGaA, Darmstadt, Germany, announced today the formation of 'Merck Serono Ventures', a strategic, corporate venture capital fund to invest in emerging biotechnology companies.

Injected luminol glows blue revealing immune cells' misdeeds

Detectives on television shows often spray crime scenes with a compound called luminol to make blood glow.

Protein called Shp2 is key to embryonic stem cell differentiation

Investigators at Burnham Institute for Medical Research (Burnham) have learned that a protein called Shp2 plays a critical role in the pathways that control decisions for differentiation or self-renewal in both human embryonic stem cells (hESCs) and mouse embryonic stem cells (mESCs).

Alzheimer's mechanism suggests combination therapy needed

Researchers at the University of Illinois at Chicago College of Medicine have discovered a mode of action for mysterious but diagnostic protein snarls found in the brains of Alzheimer's patients that suggests a one-two punch of therapy may be needed to combat the neurodegenerative disease.

A living representation of the brain created by scientists

Researchers in the School of Life & Health Sciences at Aston University in Birmingham, UK are developing a novel new way to model how the human brain works by creating a living representation of the brain.

A biomarker test to diagnose or rule out Alzheimer's disease

A test capable of confirming or ruling out Alzheimer's disease has been validated and standardized by researchers at the University of Pennsylvania School of Medicine.

Alzheimer's disease neuroimaging initiative announces completion of genome-wide analysis

Researchers announced today that a high-density genome wide analysis of participants in the Alzheimer's Disease Neuroimaging Initiative (ADNI; www.adni-info.org) is more than 95% complete and that data will be shared with scientists around the world for further analysis.

Parkinson's-linked mutation makes neurons vulnerable to calcium-induced death

A new study reveals the mechanism by which a genetic mutation linked with Parkinson's disease (PD) renders dopamine neurons particularly vulnerable to cell injury and death.

Can brain training games help prevent Alzheimer's?

Loss of thinking power is a fear shared by many aging baby boomers.

Naked mole rats may hold clues to successful aging

Naked mole rats resemble pink, wrinkly, saber-toothed sausages and would never win a beauty contest, even among other rodents.

New clues about mitochondrial 'growth spurts'

Mitochondria are restless, continually merging and splitting. But contrary to conventional wisdom, the size of these organelles depends on more than fusion and fission, as Berman et al. show. Mitochondrial growth and degradation are also part of the equation.

2 Mar 2009

Investigational protein may reverse neurodegenerative diseases

An investigational protein that transformed normal laboratory mice into super-jocks holds great promise in developing new treatments for neurodegenerative diseases like Parkinson's, Alzheimer's and ALS (Lou Gehrig's Disease), say researchers at the University of Virginia Health System.
