Neurodegeneration is the umbrella term for the progressive loss of structure or function of neurons, including death of neurons.

Scientists wrestle to understand why Huntington's can produce variable symptoms

Scientists have wrestled to understand why Huntington's disease, which is caused by a single gene mutation, can produce such variable symptoms. An authoritative review by a group of leading experts summarizes the progress relating cell loss in the striatum and cerebral cortex to symptom profile in Huntington's disease, suggesting a possible direction for developing targeted therapies.

Study demonstrates effects of obesity on 'Taupathies'

In France, more than 860,000 people suffer from Alzheimer's disease and related disorders, making them the largest cause of age-related loss of intellectual function. Cognitive impairments observed in Alzheimer's disease result from the accumulation of abnormal tau proteins in nerve cells undergoing degeneration . We know that obesity, a major risk factor in the development of insulin resistance and type 2 diabetes, increases the risk of dementia during the aging process.

Researchers show that protein p62 balances metabolism in fat tissue

In many cases, obesity is caused by more than just overeating and a lack of exercise. Something in the body goes haywire, causing it to store more fat and burn less energy. But what is it? Researchers at Sanford-Burnham Medical Research Institute have a new theory-a protein called p62.

Top-line results from Biogen Idec’s dexpramipexole Phase 3 trial on amyotrophic lateral sclerosis

Today Biogen Idec reported top-line results of EMPOWER, a Phase 3 trial investigating dexpramipexole in people with amyotrophic lateral sclerosis (ALS).

Study identifies mechanism by which bacterium S. aureus colonizes nasal passages

A collaboration between researchers at the School of Biochemistry and Immunology and the Department of Microbiology at Trinity College Dublin has identified a mechanism by which the bacterium Staphylococcus aureus (S. aureus) colonizes our nasal passages. The study, published today in the Open Access journal PLOS Pathogens, shows for the first time that a protein located on the bacterial surface called clumping factor B (ClfB) has high affinity for the skin protein loricrin.

FUS RNA binding ability essential for development of Amyotrophic Lateral Sclerosis

Research led by Dr. Udai Pandey, Assistant Professor of Genetics at LSU Health Sciences Center New Orleans, has found that the ability of a protein made by a gene called FUS to bind to RNA is essential to the development of Amyotrophic Lateral Sclerosis (ALS). This discovery identifies a possible therapeutic target for the fatal neurological disease.

Link between silent stroke and Parkinson's disease

Scientists at The University of Manchester have for the first time identified why a patient who appears outwardly healthy may develop Parkinson's disease.

Administration of N2O + ISO appears to have negative effect on fetal development

An anesthetic regimen typically used during surgery on pregnant mothers appears to have a negative effect on the development of the fetus, according to a new study on mice conducted by neurobiologists from the National Center for Toxicological Research, in Arizona.

Dementia therapy: an interview with Assoc Prof. Olivier Piguet and Sharon Savage

Dementia is the umbrella term used to describe a number of neurodegenerative brain disorders that cause progressive changes in thinking abilities and behaviour. The kind of deficits experienced by individuals diagnosed with dementia depends on the location and severity of the pathology in the brain.

Lack of TDP-43 protein can lead to frontotemporal dementia/ALS

Researchers at Mayo Clinic in Florida have uncovered a toxic cellular process by which a protein that maintains the health of neurons becomes deficient and can lead to dementia.

Scientists develop MitoFish for in vivo studies of mitochondria transport in nerve cells

Scientists have demonstrated a new way to investigate mechanisms at work in Alzheimer's and other neurodegenerative diseases, which also could prove useful in the search for effective drugs. For new insights, they turned to the zebrafish, which is transparent in the early stages of its life. The researchers developed a transgenic variety, the "MitoFish," that enables them to see - within individual neurons of living animals - how brain diseases disturb the transport of mitochondria, the power plants of the cell.

psi-GSH prevents neurodegeneration associated with Alzheimer's in mouse model

Researchers at the University of Minnesota's Center for Drug Design have developed a synthetic compound that, in a mouse model, successfully prevents the neurodegeneration associated with Alzheimer's disease.

Study describes 68 cases of chronic traumatic encephalopathy in athletes, military veterans

A study done by investigators at the Boston University Center for the Study of Traumatic Encephalopathy (CSTE) and the Veterans Affairs Boston Healthcare System, in collaboration with the Sports Legacy Institute (SLI), describes 68 cases of chronic traumatic encephalopathy (CTE) among deceased athletes and military veterans whose brain and spinal cords were donated to the VA CSTE Brain Bank.

microRNAs play an important role during embryonic development

Sanford-Burnham researchers discover that microRNAs play an important role in germ layer formation-the process that determines which cells become which organs during embryonic development

Lewy pathology out of favor as Parkinson’s culprit

Neurodegeneration and cellular dysfunction may precede the appearance of Lewy bodies in the substantia nigra, shows research that challenges the role of Lewy pathology in Parkinson’s disease.

Two Sanford-Burnham projects win International Space Station Research Competition

Sanford-Burnham Medical Research Institute (Sanford-Burnham) today announced that two of the Institute's research teams have won Space Florida's International Space Station (ISS) Research Competition. Eight teams were selected from a pool of international applicants to send experiments to space in late 2013.

Novel SIRT2 inhibitor protects against neuronal damage in animal models of Huntington's

Treatment with a novel agent that inhibits the activity of SIRT2, an enzyme that regulates many important cellular functions, reduced neurological damage, slowed the loss of motor function and extended survival in two animal models of Huntington's disease.

New paper describes MCUR1 protein and its function

Most healthy cells rely on a complicated process to produce the fuel ATP. Knowing how ATP is produced by the cell's energy storehouse - the mitochondria -- is important for understanding a cell's normal state, as well as what happens when things go wrong, for example in cancer, cardiovascular disease, neurodegeneration, and many rare disorders of the mitochondria.

Carnosic acid promotes eye health

Herbs widely used throughout history in Asian and early European cultures have received renewed attention by Western medicine in recent years. Scientists are now isolating the active compounds in many medicinal herbs and documenting their antioxidant and anti-inflammatory activities. In a study published in the journal Investigative Ophthalmology & Visual Science, Stuart A. Lipton, M.D., Ph.D. and colleagues at Sanford-Burnham Medical Research Institute (Sanford-Burnham) report that carnosic acid, a component of the herb rosemary, promotes eye health.

High-resolution real-time images show how nerves may be damaged during earliest stages of MS

High-resolution real-time images show in mice how nerves may be damaged during the earliest stages of multiple sclerosis. The results suggest that the critical step happens when fibrinogen, a blood-clotting protein, leaks into the central nervous system and activates immune cells called microglia.
