One-time treatment slows onset and progression of ALS, study finds

Studies of a therapy designed to treat amyotrophic lateral sclerosis suggest that the treatment dramatically slows onset and progression of the deadly disease, one of the most common neuromuscular disorders in the world.

Combined transplantation provides potential new therapy for repair of spinal cord injury

Following spinal cord injury, astrocyte proliferation and scar formation are the main factors inhibiting the regeneration and growth of spinal cord axons, leading to motor and sensory function loss below the level of spinal cord injury.

Researchers find key mechanism behind Alzheimer's disease

Alzheimer's disease affects more than 26 million people worldwide. It is predicted to skyrocket as boomers age-nearly 106 million people are projected to have the disease by 2050.

Study suggests Braintone has neuroprotective effects on ischemia-induced brain damage

Recently, the importance of the neurovascular unit, which is comprised of neurons, endothelial cells and astrocytes, has received great attention in the field of stroke, because stroke affects not only neurons, but also astrocytes and microvessels.

Brain tumor cells in arrested development contribute to cell variety that protects cancer

A program that pushes immature cells to grow up and fulfill their destiny as useful, dedicated cells is short-circuited in the most common and deadly form of brain tumor, scientists at The University of Texas MD Anderson Cancer Center report this week in the Early Edition of the Proceedings of the National Academy of Sciences.

Astrocytes can protect brain tissue and reduce disability due to stroke

One of regenerative medicine's greatest goals is to develop new treatments for stroke. So far, stem cell research for the disease has focused on developing therapeutic neurons - the primary movers of electrical impulses in the brain - to repair tissue damaged when oxygen to the brain is limited by a blood clot or break in a vessel. New UC Davis research, however, shows that other cells may be better suited for the task.

NIH awards $1.7M grant to develop effective treatments for brain disorders

Ten percent of Americans experience a seizure in their lifetime, with three million diagnosed with epilepsy, a chronic neurological disorder. Anticonvulsant medications can mitigate the hyperactivity of neurons that leads to seizures, but not without severe side effects, including cognitive impairment.

New research finding raises questions about common mutant forms of JC polyomavirus

The JC polyomavirus is clearly opportunistic. It infects half the population but lethally destroys brain tissue only in immunocompromised patients - and it may be outright sneaky, too. Even as a new research paper allays fears that common mutant forms of the virus are the ones directly responsible for the disease's main attack, that same finding raises new questions about what the mutants are doing instead.

Researchers find way to differentiate iPSCs into mature human neurons in the brain

Difficult-to-study diseases such as Alzheimer's, schizophrenia, and autism now can be probed more safely and effectively thanks to an innovative new method for obtaining mature brain cells called neurons from reprogrammed skin cells. According to Gong Chen, the Verne M. Willaman Chair in Life Sciences and professor of biology at Penn State University and the leader of the research team, "the most exciting part of this research is that it offers the promise of direct disease modeling, allowing for the creation, in a Petri dish, of mature human neurons that behave a lot like neurons that grow naturally in the human brain."

Scientists pinpoint genetic traits of cells that give rise to gliomas

A multi-institutional team of researchers have pinpointed the genetic traits of the cells that give rise to gliomas - the most common form of malignant brain cancer. The findings, which appear in the journal Cell Reports, provide scientists with rich new potential set of targets to treat the disease.

Isaiah J. Fidler earns 2013 American Cancer Society Medal of Honor for Basic Research

When Isaiah J. Fidler, D.V.M., Ph.D., left his veterinary surgical practice to pursue a doctorate that would allow him to study and combat the lethal spread of cancer to other organs, he got lots of advice. The common message: Don't go there.

Scientists reexamine gene strongly linked to Alzheimer's disease

Scientists' picture of how a gene strongly linked to Alzheimer's disease harms the brain may have to be revised, researchers at Washington University School of Medicine in St. Louis have found. People with harmful forms of the APOE gene have up to 12 times the risk of developing Alzheimer's disease compared with those who have other variations of the gene.

Complex network of molecules controls formation and activity of neuronal connections

Environment moulds behaviour - and not just that of people in society, but also at the microscopic level. This is because, for their function, neurons are dependent on the cell environment, the so-termed extracellular matrix.

Researchers identify genetic mutation linked to a typical form of migraine

A research team led by a Howard Hughes Medical Institute investigator at the University of California, San Francisco has identified a genetic mutation that is strongly associated with a typical form of migraine.

New methods to evaluate how astrocytes contribute to brain function

A study in The Journal of General Physiology presents new methods to evaluate how astrocytes contribute to brain function, paving the way for future exploration of these important brain cells at unprecedented levels of detail.

Astrocytes more effective in promoting recovery after brain injury

The production of a certain kind of brain cell that had been considered an impediment to healing may actually be needed to staunch bleeding and promote repair after a stroke or head trauma, researchers at Duke Medicine report.

New research reveals how acute stress primes brain for improved performance

Overworked and stressed out? Look on the bright side. Some stress is good for you. "You always think about stress as a really bad thing, but it's not," said Daniela Kaufer, associate professor of integrative biology at the University of California, Berkeley.

Study provides detail on cellular-level effects of anesthetics on developing brain in newborn mouse

Exposure to the anesthetic agent isoflurane increases "programmed cell death" of specific types of cells in the newborn mouse brain, reports a study in the April issue of Anesthesia & Analgesia, official journal of the International Anesthesia Research Society.

Study applying OPKO Health's technology to identify synthetic peptoid in NMO patient serum published

OPKO Health, Inc. today announced the publication of a study applying its novel library screening technology to identify a synthetic peptoid that binds to anti-Aquaporin 4 antibodies in the serum of patients with Neuromyelitis optica.

Salk neuroscientist applauds launch of BRAIN Initiative

Salk neuroscientist Terrence J. Sejnowski joined President Barack Obama in Washington, D.C., on April 2, 2013, at the launch of the Brain Research through Advancing Innovative Neurotechnologies Initiative-a major Administration neuroscience effort that advances and builds upon collaborative scientific work by leading brain researchers such as Salk's own Sejnowski.
