Tau release from healthy neurons can be regulated by neuronal activity

Researchers from King's College London have discovered that neuronal activity can stimulate tau release from healthy neurons in the absence of cell death.

Protein-restricted diet supplemented with IGF-I may protect from Alzheimer's

Mice with many of the pathologies of Alzheimer's Disease showed fewer signs of the disease when given a protein-restricted diet supplemented with specific amino acids every other week for four months.

Stress and mental illness: an interview with Professor Akira Sawa

As a psychiatrist I am interested in how stress may play a role in the pathology of adult mental disorders. You may know that most of the major mental illnesses, such as schizophrenia, mood-disorder, substance abuse or even anxiety disorder, become prominent in early adulthood.

CELF6 genetic mutation may underlie common behaviors seen in people with autism

Scientists at Washington University School of Medicine in St. Louis have identified a genetic mutation that may underlie common behaviors seen in some people with autism, such as difficulty communicating and resistance to change.

Study demonstrates how CN2097 works to restore neural functions impaired by Angelman syndrome

In a new study in mice, a scientific collaboration centered at Brown University lays out in unprecedented detail a neurological signaling breakdown in Angelman syndrome, a disorder that affects thousands of children each year, characterized by developmental delay, seizures, and other problems.

Abnormal TDP-43 protein causes death of astrocytes in motor neurone disease

A discovery using stem cells from a patient with motor neurone disease could help research into treatments for the condition. The study used a patient's skin cells to create motor neurons - nerve cells that control muscle activity - and the cells that support them called astrocytes.

Developing tiny probes for research and brain-related medical applications

Developing tiny probes for research and brain-related medical applications - that is the goal of the project NeuroSeeker, launched in February 2013 with a kick-off event in Leuven, Belgium.

Researchers discover miR-27b that regulates lipid levels in the blood

Researchers have identified a microRNA liver gene, miR-27b, which regulates lipid (cholesterol or fat) levels in the blood. This regulator gene controls multiple genes involved in dyslipidemia-abnormal blood cholesterol levels that can contribute to heart disease.

Dkk1 molecule accumulates with age and inhibits formation of new neurons

As the elderly age, their ability to concentrate, reason, and recall facts tends to decline in part because their brains generate fewer new neurons than they did when they were younger. Now, researchers reporting in the February 7th issue of the Cell Press journal Cell Stem Cell have discovered a molecule that accumulates with age and inhibits the formation of new neurons.

sFRP3 protein appears to be target of both antidepressant drugs and electroconvulsive therapy

Through a series of investigations in mice and humans, Johns Hopkins researchers have identified a protein that appears to be the target of both antidepressant drugs and electroconvulsive therapy.

Overexpression of alpha-synuclein can cause Parkinson's

Researchers at the University of California, San Diego School of Medicine say overexpression of a protein called alpha-synuclein appears to disrupt vital recycling processes in neurons, starting with the terminal extensions of neurons and working its way back to the cells' center, with the potential consequence of progressive degeneration and eventual cell death.

Reprogrammed human skin cells highly effective in treating myelin disorders

A study out today in the journal Cell Stem Cell shows that human brain cells created by reprogramming skin cells are highly effective in treating myelin disorders, a family of diseases that includes multiple sclerosis and rare childhood disorders called pediatric leukodystrophies.

Broken motors induce stress and anxiety in mice

When motors break down, getting where you want to go becomes a struggle. Problems arise in much the same way for critical brain receptors when the molecular motors they depend on fail to operate. Now, researchers reporting in Cell Reports, a Cell Press publication, on February 7, have shown these broken motors induce stress and anxiety in mice. The discovery may point the way to new kinds of drugs to treat anxiety and other disorders.

Study finds reason why patients with chronic pain often suffer from impaired short -term memory

A group of Portuguese researchers from IBMC and FMUP at the University of Porto has found the reason why patients with chronic pain often suffer from impaired short -term memory.

Drugs that target retromer pathway could help prevent or treat Parkinson's

Columbia University Medical Center (CUMC) researchers have identified a protein trafficking defect within brain cells that may underlie common non-familial forms of Parkinson's disease.

Basis of antidepressant drugs and electroconvulsive therapy found

Through a series of investigations in mice and humans, Johns Hopkins researchers have identified a protein that appears to be the target of both antidepressant drugs and electroconvulsive therapy. Results of their experiments explain how these therapies likely work to relieve depression by stimulating stem cells in the brain to grow and mature.

Liver gene found to regulate cholesterol and fat blood levels

Researchers have identified a microRNA liver gene, miR-27b, which regulates lipid (cholesterol or fat) levels in the blood. This regulator gene controls multiple genes involved in dyslipidemia—abnormal blood cholesterol levels that can contribute to heart disease.

Migraine, epilepsy and genetics: an interview with Dr. Melodie Winawer

This work is the product of an extraordinary consortium called the Epilepsy Phenome/Genome project (EPGP). It is a consortium of 27 centres in the U.S. and internationally with several hundred physicians and staff who have worked together to enrol more than 4000 patients with epilepsy and their family members.

Study findings suggest physical and pharmacological solutions for human stroke victims

Johns Hopkins researchers have found that mice can recover from physically debilitating strokes that damage the primary motor cortex, the region of the brain that controls most movement in the body, if the rodents are quickly subjected to physical conditioning that rapidly "rewires" a different part of the brain to take over lost function.

DCC receptor plays key role in regulating brain plasticity

Our ability to learn and form new memories is fully dependent on the brain's ability to be plastic - that is to change and adapt according to new experiences and environments. A new study from the Montreal Neurological Institute - The Neuro, McGill University, reveals that DCC, the receptor for a crucial protein in the nervous system known as netrin, plays a key role in regulating the plasticity of nerve cell connections in the brain.
