Study: Astrocytes regulate neuronal circuits involved in learning and memory

Researchers at Baylor College of Medicine reveal that astrocytes, the most abundant cells in the brain, play a direct role in the regulation of neuronal circuits involved in learning and memory. The findings appear in the journal Neuron.

Research shows how stress changes structure of the brain

Research led by Si-Qiong June Liu, MD, Ph.D., Professor of Cell Biology and Anatomy at LSU Health New Orleans School of Medicine, has shown how stress changes the structure of the brain and reveals a potential therapeutic target to the prevent or reverse it

Large-scale proteomic analysis links glucose metabolism proteins and AD biology

In the largest study to date of proteins related to Alzheimer's disease, a team of researchers has identified disease-specific proteins and biological processes that could be developed into both new treatment targets and fluid biomarkers.

Research shows how stress restructures the brain

Stress restructures the brain by halting the production of crucial ion channel proteins, according to research in mice recently published in JNeurosci.

Gene therapy regenerates functional new neurons in mouse models of HD

Huntington's disease (HD) is a rare disease characterized by abnormal chorea movement and caused by Huntingtin (Htt) gene mutation and neurodegeneration in a brain area called striatum.

Researchers discover glial cells that control stress response, extend lifespan in worms

While many of us worry about proteins aggregating in our brains as we age and potentially causing Alzheimer's disease or other types of neurodegeneration, we may not realize that some of the same proteins are aggregating in our muscles, setting us up for muscle atrophy in old age.

New study describes inflammatory reaction in lab-developed human astrocytes

Astrocytes are neural cells with many important functions in the nervous system. The inflammation of these cells occurs in brain infections and neurodegenerative disorders, a process called astrogliosis.

Surprising discovery about childhood brain tumor may unlock new cancer treatments

A surprising discovery about a rare form of childhood brain cancer suggests a new treatment approach for that cancer and, potentially, many others.

Researchers culture human blood-brain barrier on a chip

A scrupulous gatekeeper stands between the brain and its circulatory system to let in the good and keep out the bad, but this porter, called the blood-brain barrier, also blocks trial drugs to treat diseases like Alzheimer's or cancer from getting into the brain.

Reduced scar formation in the central nervous system

Neural stem and progenitor cells, from the so-called subventricular zone, can help to repair a brain damaged by central nervous system disorders.

Buck study uncovers how astrocyte senescence promotes neurodegeneration

Although a link has been established between chronic inflammation and neurodegenerative diseases, there have been many open questions regarding how cellular senescence, a process whereby cells that stop dividing under stress spew out a mix of inflammatory proteins, affects these pathologies.

Scientists reveal the damaging effect of Zika virus on a type of brain cell

The Zika virus (ZIKV) outbreak in Brazil in 2015 sparked for many health agencies and scientists to study the pathogen, which has been linked to microcephaly and other fetal neurological disorders collectively known as Congenital Zika Syndrome.

Research unravels consequences of Zika virus attack on neural cells

Previous studies regarding the damage of the Zika virus on the brain had already pointed out the virus's predilection for a certain neural cell: the astrocyte. However, few studies have proposed to identify the infection effects on these cells, as well as their association with developmental alterations, including brain malformations and microcephaly.

Finding opens door to early identification of individuals at risk for delirium complications

Regenstrief Institute and Indiana University School of Medicine researchers have identified blood-based biomarkers associated with both delirium duration and severity in critically ill patients. This finding opens the door to easy, early identification of individuals at risk for longer delirium duration and higher delirium severity and could potentially lead to new treatments of this brain failure for which drugs have been shown to be largely ineffective.

Researchers find potential new target for treating drug addiction

New University of Minnesota Medical School research discovers a novel potential target for treating drug addiction through "the hidden stars of the brain."

Discovery could lead to new treatments for hypertension, dementia

A study led by researchers at UCL has discovered the mechanism that allows the brain to monitor its own blood supply, a finding in rats which may help to find new treatments for human conditions including hypertension (high blood pressure) and dementia.

Researchers discover molecular underpinnings of Alexander disease

Scientists have known that genetic mutations leading to the production of a defective protein called GFAP cause Alexander disease (AxD), a debilitating neurodegenerative condition that can present during infancy, adolescence, or adulthood.

KAUST researchers one step closer to understanding brain function

Researchers at King Abdullah University of Science and Technology (KAUST) are officially one-step closer to understanding the brain and its function.

Long-term exposure to toxic chemicals in the environment impairs brain function in mice

Human-made toxic chemicals that linger indefinitely in the environment disrupt the performance of critical helper cells in the mouse brain, leading to impaired function over long-term exposures, say neuroscientists at Georgetown University Medical Center.

New gene therapy helps stroke patients develop new neurons

Ischemic stroke is a condition in which parts of the brain lose their blood supply, causing nerve damage. Once brain tissue suffers irreparable harm, the patient will experience irreversible disability or death, depending on the extent of neuronal loss.
