Glia plays key role in preventing progression of Rett Syndrome symptoms

A paper published online today in Nature reveals that glia play a key role in preventing the progression of the most prominent Rett Syndrome symptoms displayed by mouse models of the disease: lethality, irregular breathing and apneas, hypoactivity and decreased dendritic complexity.

Growth-braking tumor-suppressor gene slows growth of childhood brain tumors

Johns Hopkins researchers have found a likely explanation for the slow growth of the most common childhood brain tumor, pilocytic astrocytoma. Using tests on a new cell-based model of the tumor, they concluded that the initial process of tumor formation switches on a growth-braking tumor-suppressor gene, in a process similar to that seen in skin moles.

Scientists find altering hormone levels change cellular development in brain

In a study that increases the understanding of the link between fetal development and obesity later in life, researchers at Los Angeles Biomedical Research Institute at Harbor-UCLA Medical Center (LA BioMed) found altering the levels of two common hormones, insulin and leptin, in utero changes the cellular development in the region of the brain that regulates appetite.

Scientists direct embryonic, induced human stem cells to become astrocytes in lab dish

Pity the lowly astrocyte, the most common cell in the human nervous system. Long considered to be little more than putty in the brain and spinal cord, the star-shaped astrocyte has found new respect among neuroscientists who have begun to recognize its many functions in the brain, not to mention its role in a range of disorders of the central nervous system.

Researchers uncover unexpected role of estrogen receptors in brain inflammation

Researchers have uncovered an unexpected role for estrogen receptors in the brain in keeping inflammation under control. The findings reported in the May 13 issue of the Cell Press journal Cell may have important implications for the treatment of multiple sclerosis (MS) and many other neurodegenerative diseases.

UCSD scientists discover steroid hormone that inhibits brain inflammation

Researchers at the University of California, San Diego School of Medicine have discovered a steroid hormone that inhibits inflammation in the brain. The findings, to be published in the May 13 issue of the journal Cell, have implications for understanding the exaggerated inflammatory responses that are characteristic features of numerous neurodegenerative diseases.

Aquaporin-4 plays a key role in brain inflammation

A new protein, called aquaporin-4, is making waves and found to play a key role in brain inflammation, or encephalitis. This discovery is important as the first to identify a role for this protein in inflammation, opening doors for the development of new drugs that treat brain inflammation and other conditions at the cellular level rather than just treating the symptoms.

Anti-depressants spur creation and survival of new brain cells after brain injury

Anti-depressants may help spur the creation and survival of new brain cells after brain injury, according to a study by neurosurgeons at the University of Rochester Medical Center.

Astrocytes regulate circadian system that controls normal sleep patterns

The circadian system that controls normal sleep patterns is regulated by a group of glial brain cells called astrocytes, according to a study published online on April 14th in Current Biology, a Cell Press publication. Neuroscientists from Tufts University School of Medicine found that disruption of astrocyte function in fruit flies ( Drosophila) led to altered daily rhythms, an indication that these star-shaped glial cells contribute to the control of circadian behavior.

Lactate plays critical role in formation of long-term memory

Researchers from Mount Sinai School of Medicine have found that lactate, a type of energy fuel in the brain, plays a critical role in the formation of long-term memory. These findings have important implications for common illnesses like Alzheimer's disease, other neurodegenerative disorders, aging-related memory impairment and diabetes. The research is published in the March 4th issue of the journal Cell.

Scientists discover specific type of human cell to treat spinal cord injuries

For the first time, scientists discovered that a specific type of human cell, generated from stem cells and transplanted into spinal cord injured rats, provide tremendous benefit, not only repairing damage to the nervous system but helping the animals regain locomotor function as well.

New molecular player responsible for regulation of appetite and metabolism

A study by researchers at Mayo Clinic's campus in Florida and Washington University School of Medicine adds a new twist to the body of evidence suggesting human obesity is due in part to genetic factors. While studying hormone receptors in laboratory mice, neuroscientists identified a new molecular player responsible for the regulation of appetite and metabolism.

Researchers identify new biological pathway that contribute to glaucoma

In a study published today in the Proceedings of the National Academy of Sciences, a team of researchers from the Kennedy Krieger Institute and four collaborating institutions, identified a new and unexpected biological pathway that appears to contribute to the development of glaucoma and its resulting vision loss.

Gilenya offers more benefits for MS therapy than previously realized

In September, patients suffering from multiple sclerosis (MS) received the welcome news that the U.S. Food and Drug Administration (FDA) had approved a promising new drug for their condition called Gilenya. Now, a team from The Scripps Research Institute has discovered that this drug's success may involve an unexpected biological mechanism acting within the central nervous system (CNS). This difference may mean that Gilenya offers even more benefits than previously realized and would represent the first MS therapy with direct CNS activities.

Bioengineers explain why some neurons die sooner than others in brains of AD patients

Bioengineers from the University of California, San Diego developed an explanation for why some types of neurons die sooner than others in the brains of people with Alzheimer's disease. These insights, published in the journal Nature Biotechnology on November 21, come from detailed models of brain energy metabolism developed in the Department of Bioengineering at the UC San Diego Jacobs School of Engineering.
