Resveratrol effective in lowering amyloid-beta peptides

A study published in the November 11 issue of the Journal of Biological Chemistry shows that resveratrol, a compound found in grapes and red wine, lowers the levels of the amyloid-beta peptides which cause the telltale senile plaques of Alzheimer's disease.

Howard Hughes Medical Institute researchers have deciphered code for motor neuron wiring

Howard Hughes Medical Institute (HHMI) researchers have deciphered a key part of the regulatory code that governs how motor neurons in the spinal cord connect to specific target muscles in the limbs.

Scientists find new mechanism by which brain cells can be damaged during chronic neurodegenerative diseases

Scientists at the University of Rochester Medical Center have targeted a new culprit and method of attack on neurologic functions in diseases such as Alzheimer's and dementia associated with HIV.

Tryptophan metabolites play an important role in the immune system

Tryptophan is the source of Thanksgiving legend and grist for a "Seinfeld" episode, but it's not the chemical that you'd expect to find in Lawrence Steinman's lab.

Neuron finding could advance understanding of epilepsy and age-related memory loss

Neurons experience large-scale changes across their dendrites during learning, say neuroscientists at The University of Texas at Austin in a new study that highlights the important role that these cell regions may play in the processes of learning and memory.

Protein called CHIP helps untangle protein misfolding in brain disease

Keeping the body and mind healthy depends on keeping cells healthy and functioning. This means that cells need a very robust quality-control system to repair or remove damaged or misshapen proteins. Protein handling is especially important in neurons because damage or death of brain cells causes neurological disease.

Bumetanide may help treat seizures in newborns

A diuretic drug called bumetanide may serendipitously help treat seizures in newborns, which are difficult to control with existing anticonvulsants, according to a study in the November Nature Medicine.

DCDC2 gene linked to dyslexia

Pediatric researchers at Yale School of Medicine have identified a gene on human chromosome 6 called DCDC2, which is linked to dyslexia, a reading disability affecting millions of children and adults.

Scientists unravel complex mechanisms in the brain that regulate body weight

Scientists are one step closer to unraveling the complex mechanisms in the brain that regulate body weight. Working with mice -- whose appetites are controlled by systems very similar to those in humans – they have identified a specific type of neuron that is essential for feeding behavior.

Scientists say there is less white matter in the frontal lobes of those who struggle with focusing

When it comes to focusing on a task amid distractions, some folks more than 60 years old are as mentally sharp as 22-year-olds. Others struggle. Researchers at the Beckman Institute for Advanced Science and Technology at the University of Illinois at Urbana-Champaign have shed some light on why that is.

New understanding of how neurogenesis occurs

Scientists at the Salk Institute for Biological Studies have identified a crucial cellular signal that controls the fate of stem cells in the brains of adult mice.

Northwestern University move closer to new therapies for neurodegenerative disease

French neurologist Jean-Martin Charcot first described amyotrophic lateral sclerosis (ALS) in 1869, but, nearly 140 years later, little is known about the cause of the devastating neurodegenerative disease, and there is no cure.

Cancer drug may be effective for Alzheimer's

According to scientists at the Blanchette Rockefeller Neurosciences Institute and the Marine Biological Laboratory, a cancer drug may stimulate the production of proteins needed for long-term memory, suggesting the compound may a possible treatment for Alzheimer's disease

Scientists find key step in a signaling pathway that helps orchestrate embryonic development

The study, reported in Nature (Oct. 13, 2005), focuses on the Hedgehog family of signaling molecules, which play a central role in directing development of the early embryo's growth and spatial plan, as well as its later organ and limb development. Defects in Hedgehog signaling are a significant cause of some birth defects and cancers.

Blocking a signaling lipid can keep nerves from developing and may even cause neurons to die

Blocking a signaling lipid can keep nerves from developing the arm-like extensions they need to wire the body and may even cause neurons to die, researchers have found.

Possible new directions for treatments for addiction to cocaine

Cocaine causes specific alterations in the brain's circuitry at a genetic level, including short-term changes that result in a high from the cocaine, as well as long-term changes seen in addiction, researchers from UT Southwestern Medical Center have found.

Diabetes drugs may also prevent nerve degeneration caused by Alzheimer's disease

Recent research has shown a surprising link between Alzheimer’s and diabetes, two of the major health challenges facing society today. According to Dr Holscher modern lifestyle promotes the development of type 2 diabetes, which in turn could drastically increase the number of people to develop Alzheimer’s disease as people with type 2 diabetes are much more likely to develop the disease than healthy people of the same age.

Neurobiologists gain new insights into brain and memory

We often make unwise choices although we should know better. Thunderstorm clouds ominously darken the horizon. We nonetheless go out without an umbrella because we are distracted and forget. But do we?
