Calcium waves could be relevant for understanding the origin of Alzheimer's disease

New insights on what causes Alzheimer's disease could arise from a recent discovery made by bioengineers from the University of California, San Diego. The finding concerns the infamous amyloid beta peptides (Aβ)-fragments of which form plaques thought to play a role in Alzheimer's disease.

M. D. Anderson researchers discover mechanism that helps glioblastomas evade immune attack

Cancer-initiating cells that launch glioblastoma multiforme, the most lethal type of brain tumor, also suppress an immune system attack on the disease, scientists from The University of Texas M. D. Anderson Cancer Center report in a paper featured on the cover of the Jan. 15 issue of Clinical Cancer Research.

RORalpha protein revealed as an essential regulator of inflammatory factors

How do the brain cells called astrocytes ensure the protection of neurons? By studying the protagonists in the protection and satisfactory functioning of neurons, scientists at the Laboratoire Neurobiologie des Processus Adaptatifs (CNRS/UPMC) have found a mechanism that clarifies the role of astrocytes.

New protein discovery may serve as potential marker of drug addiction

Scientists are adding additional brush strokes to the revolutionary new image now emerging for star-shaped cells called astrocytes in the brain and spinal cord. Their report, which suggests a key role for astrocytes in morphine's ability to relieve pain and cause addiction, appears online in ACS' Journal of Proteome Research, a monthly publication.

Neurotoxic heavy metal can slow the progression of Lou Gehrig's disease

New discoveries have been made about how an elevated level of lead, which is a neurotoxic heavy metal, can slow the progression of amyotrophic lateral sclerosis, or Lou Gehrig's disease - findings that could point the way to a new type of therapy.

Foods rich in antioxidant substances could delay the onset of Alzheimer's disease

Universitat Autònoma de Barcelona (UAB) researchers have confirmed that a diet rich in polyphenols and polyunsaturated fatty acids, patented as an LMN diet, helps boost the production of the brain's stem cells -neurogenesis- and strengthens their differentiation in different types of neuron cells.

Cancer promoting gene identified

Virginia Commonwealth University Massey Cancer Center and VCU Institute of Molecular Medicine researchers have identified a gene that may play a pivotal role in two processes that are essential for tumor development, growth and progression to metastasis. Scientists hope the finding could lead to an effective therapy to target and inhibit the expression of this gene resulting in inhibition of cancer growth.

Long-term effects of statin therapy could lead to transient or permanent cognitive impairment

Besides their tremendous value in treating high cholesterol and lowering the risk of heart disease, statins have also been reported to potentially lower the risks of other diseases, such as dementia. However, a study in the October Journal of Lipid Research finds that similar statin drugs can have profoundly different effects on brain cells -both beneficial and detrimental.

NIH awards $3.7 million to Johns Hopkins scientists for research on stem cells developed from ALS patients' skin

Johns Hopkins scientists have been awarded a $3.7 million grant from the National Institutes of Health (NIH) to learn more about the nerve and muscle-wasting disease amyotrophic lateral sclerosis (ALS) using stem cells developed from ALS patients' skin. The award, given over a two-year span, will be shared with three other laboratories, including one at Harvard University and two at Columbia University.

Astrocytes play a key role in the generation of fMRI signals

Functional magnetic resonance imaging (fMRI) is a technique widely used in studying the human brain. However, it has long been unclear exactly how fMRI signals are generated at brain cell level. This information is crucially important to interpreting these imaging signals. Scientists from the Academy of Finland's Neuroscience Research Programme (NEURO) have discovered that astrocytes, support cells in brain tissue, play a key role in the generation of fMRI signals.

Scientists study the impact of nerve growth factors for treating Parkinson's disease

Scientists in the Academy of Finland's Neuroscience Research Programme have reported promising new results with potential implications for the treatment of Parkinson's disease. They have been studying the impacts of nerve growth factors in the treatment of PD, and their latest results show that a certain growth factor can be used to halt the progress of damage brought on by a nerve poison and possibly even restore the function of damaged cells.
