Study finds key association between Kallikrein 6 and malignant tumors

One of the most common types of brain tumors in adults, glioblastoma multiforme, is one of the most devastating. Even with recent advances in surgery, radiation and chemotherapy, the aggressive and invasive tumors become resistant to treatment, and median survival of patients is only about 15 months. In a study published in Neuro-Oncology, researchers at Mayo Clinic identify an important association between the naturally occurring enzyme Kallikrein 6, also known as KLK6, and the malignant tumors.

Some epileptic seizures may originate in glia: Study

Epileptic seizures occur when neurons in the brain become excessively active. However, a new study from MIT neuroscientists suggests that some seizures may originate in non-neuronal cells known as glia, which were long believed to play a mere supporting role in brain function.

Study examines five varieties of cells after transplantation in the CNS

When different types of cells are transplanted with the intent of having them aid in repairing central nervous system (CNS) trauma, what is the fate and function of those cells? A Belgian research team carried out research aimed at answering this question by determining how five varieties of cells - neural stem cells, mouse embryonic fibroblasts, dendritic cells, bone marrow mononuclear cells (BMMNCs) and splenocytes - functioned and survived after transplantation in the CNS.

Activated astrocytes could play a harmful role in Alzheimer's disease

A research team composed of University of Kentucky researchers has published a paper which provides the first direct evidence that activated astrocytes could play a harmful role in Alzheimer's disease.

Researchers unlock complex cellular mechanics that instruct glial progenitor cells to divide

In a new study appearing this month in the Journal of Neuroscience, researchers have unlocked the complex cellular mechanics that instruct specific brain cells to continue to divide. This discovery overcomes a significant technical hurdle to potential human stem cell therapies; ensuring that an abundant supply of cells is available to study and ultimately treat people with diseases.

Mouse model may provide clues on mechanism that links diabetes and aging to Alzheimer's

Growing evidence suggests that there may be a link between diabetes and Alzheimer's disease, but the physiological mechanisms by which diabetes impacts brain function and cognition are not fully understood. In a new study published in Aging Cell, researchers at the Salk Institute for Biological Studies show, for the first time, that diabetes enhances the development of aging features that may underlie early pathological events in Alzheimer's.

Glioblastoma multiforme can originate from cortical neurons

Scientists have long believed that glioblastoma multiforme (GBM), the most aggressive type of primary brain tumor, begins in glial cells that make up supportive tissue in the brain or in neural stem cells. In a paper published October 18 in Science Express, however, researchers at the Salk Institute for Biological Studies have found that the tumors can originate from other types of differentiated cells in the nervous system, including cortical neurons.

Researchers identify astrocytes as new target for Alzheimer's

Alzheimer's disease is a severe neurodegenerative disease that affects 45% of people over 85 years of age. The research teams of Prof. Jin-Moo Lee at Washington University in Saint Louis, USA, and Prof. Milos Pekny at Sahlgrenska Academy in Gothenburg, Sweden, have identified astrocytes as a novel target for the development of future treatment strategies. The results have just been published in the FASEB Journal.

Anesthetic-loaded liposomes can delay onset of neuropathic pain

Using tiny spheres filled with an anesthetic derived from a shellfish toxin, researchers at Boston Children's Hospital and the Massachusetts Institute of Technology have developed a way to delay the rise of neuropathic pain, a chronic form of pain that arises from flawed signals transmitted by damaged nerves.

Study shows how astrocytes control new neuron generation in the brain

Researchers from the Laboratory of astrocyte biology and CNS regeneration headed by Prof. Milos Pekny just published a research article in a prestigious journal Stem Cells on the molecular mechanism that controls generation of new neurons in the brain.

Astrocytes help reduce damaging effects of epilepsy

Epileptic fits are like thunderstorms raging in the brain: Nerve cells excite each other in an uncontrolled way so that strong, rhythmic electrical discharges sweep over whole brain regions. In the wake of such a seizure, the nerve cells are severely affected, and permanent damage is possible. The glia, a class of cells that surround the neurons in the brain, was long suspected to contribute to the damaging effects of epilepsy.

Fusion of FGFR and TACC gene leads to glioblastoma

Researchers at Columbia University Medical Center (CUMC) have discovered that some cases of glioblastoma, the most common and aggressive form of primary brain cancer, are caused by the fusion of two adjacent genes.

Synthetic triterpenoids block development of Parkinson's disease

A new and powerful class of antioxidants could one day be a potent treatment for Parkinson's disease, researchers report.

Relationship between two biological risk factors for schizophrenia

Johns Hopkins researchers say they have discovered a cause-and-effect relationship between two well-established biological risk factors for schizophrenia previously believed to be independent of one another.

Oligodendroglia cells: An interview with Jeffrey Rothstein

There are three principle cells in the brain: neurons and two types of glial cells. One type is called an astrocyte. These were well known to inactivate neurotransmitters like glutamate, and provide metabolic support to neurons.

Mouse model demonstrates role of AEG-1 in hepatocellular carcinoma

Researchers have created the first mouse model demonstrating the role of a cancer promoting gene, Astrocyte elevated gene-1 (AEG-1), in hepatocellular carcinoma, or liver cancer. The mouse model represents a critical step in understanding the molecular mechanisms of liver cancer progression and could lead to novel therapies for the disease.
