Researchers identify role of Merlin in regulating integrity of axons

One in 25,000 people worldwide is affected by neurofibromatosis type 2 (NF2), a condition where the loss of a tumour suppressor called Merlin results in multiple tumours in the brain and nervous system.

Study: Multiple sclerosis patients with cognitive problems have more brain damage

People with multiple sclerosis who have cognitive problems, or problems with memory, attention, and concentration, have more damage to areas of the brain involved in cognitive processes than people with MS who do not have cognitive problems, according to a study published in the March 6, 2013, online issue of Neurology, the medical journal of the American Academy of Neurology.

Study reveals increased dietary salt intake may lead to autoimmune disorders

Increased dietary salt intake can induce a group of aggressive immune cells that are involved in triggering and sustaining autoimmune diseases.

UCLA scientists discover new genetic risk factor for Alzheimer's disease

Scientists at UCLA have discovered a new genetic risk factor for Alzheimer's disease by screening people's DNA and then using an advanced type of scan to visualize their brains' connections.

Study now tells physicians that dystonia can occur in African-American patients

A pair of studies tells the tale of how a neuroscientist at Mayo Clinic in Florida helped to discover the first African-American family to have inherited the rare movement disorder dystonia, which causes repetitive muscle contractions and twisting, resulting in abnormal posture.

‘New Frontiers in Neurodegenerative Disease Research’ symposium to be held from Feb. 4-7

At the Keystone Symposium "New Frontiers in Neurodegenerative Disease Research," held 4-7 February in Santa Fe, New Mexico, researchers explored the processes that lead to a variety of diseases, including Alzheimer's and Lou Gehrig's disease (amyotrophic lateral sclerosis, ALS).

CALHM1 protein plays critical role in sweet, bitter and umami taste perception

Working with a multidisciplinary consortium of 19 researchers from nine institutions, Monell scientists have provided critical information to identify CALHM1, a channel in the walls of taste receptor cells, as a necessary component in the process of sweet, bitter, and umami (savory) taste perception.

MicroRNA expression signatures may help define progression of Barrett's esophagus

A series of microRNA expression signatures that may help to define progression of the precancerous condition Barrett's esophagus into esophageal adenocarcinoma was reported recently in Cancer Prevention Research, a journal of the American Association for Cancer Research.

Research illuminates why stimulating environment may protect against Alzheimer's disease

"Use it or lose it." The saying could apply especially to the brain when it comes to protecting against Alzheimer's disease.

Increased blood and oxygen flow to pre-frontal area of brain may explain effects

The resulting increased blood and oxygen flow to the pre-frontal cortex may explain the effects, suggest the researchers.

Yale researchers identify key genetic switch for brain maturation

The flip of a single molecular switch helps create the mature neuronal connections that allow the brain to bridge the gap between adolescent impressionability and adult stability.

Insight into how Th17 cell growth influences development of immune responses

New work from the Broad Institute's Klarman Cell Observatory, Brigham and Women's Hospital, Harvard University, MIT, and Yale University expands the understanding of how one type of immune cell - known as a T helper 17 or Th17 cell - develops, and how its growth influences the development of immune responses.

Parietal brain cells sort visual information into categories: Study

A region of the brain known to play a key role in visual and spatial processing has a parallel function: sorting visual information into categories, according to a new study by researchers at the University of Chicago.

Carbamylation contributes to heart disease risk among patients with CKD undergoing dialysis

Kidney failure affects 25 million individuals in the U.S. and many more throughout the world. Loss of kidney function means the majority of these patients must undergo dialysis treatments to remove excess fluids and waste products. Although dialysis therapy coupled with medication has improved the life expectancy for people with kidney failure, for unknown reasons, patients' risk of sudden heart failure and death remains 10 to 20 times greater than average.

Study investigates how cancer cells 'hijack' platelets

A new research study has investigated how cancer cells 'hijack' blood cells known as platelets, enabling cancer to spread around the body and promoting the growth of new tumours, it was reported today at the annual Royal College of Surgeons in Ireland (RCSI) Research Day.

mTORC2 plays key role in regulating memory formation

Introductions at a party seemingly go in one ear and out the other. However, if you meet someone two or three times during the party, you are more likely to remember his or her name. Your brain has taken a short-term memory - the introduction - and converted it into a long-term one.

High HDL levels block development of aneurysms in the aorta

New research provides early evidence that 'good' cholesterol may possess anti-aneurysm forming properties. In laboratory-based investigations, scientists found that increased levels of high-density lipoproteins (HDL), the so-called good cholesterol, blocked the development of aneurysms - dangerous 'ballooning' in the wall of a blood vessel - in the body's largest artery, the aorta.

Salt can induce and worsen pathogenic immune system responses in mice

For the past few decades, health officials have been reporting increases in the incidence of autoimmune diseases such as multiple sclerosis (MS). Now researchers at Yale School of Medicine, Harvard Medical School and the Broad Institute have identified a prime suspect in the mystery - dietary salt.

Scientists pinpoint neural basis for stress-related relapse in rat models

All too often, stress turns addiction recovery into relapse, but years of basic brain research have provided scientists with insight that might allow them develop a medicine to help. A new study in the journal Neuron pinpoints the neural basis for stress-related relapse in rat models to an unprecedented degree.

Researchers discover likely origin of epithelial ovarian cancer

Cornell University researchers have discovered a likely origin of epithelial ovarian cancer (ovarian carcinoma), the fifth leading cause of cancer death among women in the United States.
