New clue found to the cause of Parkinson's disease

A glitch in the mechanism by which cells recycle damaged components may trigger Parkinson's disease, according to a study by scientists at the Albert Einstein College of Medicine of Yeshiva University.

Overexcited neurons not good for cell health

Neurotransmitters have consequences. They initiate events that are critical to a healthy life, giving us the ability to move, to talk, to breathe, to think. But that's if the neurotransmitters are getting it right and sending proper signals downstream to muscle cells, neurons or other cells.

Aging gracefully requires taking out the trash

Suppressing a cellular cleanup-mechanism known as autophagy can accelerate the accumulation of protein aggregates that leads to neural degeneration.

Immune system may target some brain synapses

A baby's brain has a lot of work to do, growing more neurons and connections.

14 Dec 2007

Biodegradable polymers with neurotransmitters promote nerve regrowth

Research reported December 11 in the journal Advanced Materials describes a potentially promising strategy for encouraging the regeneration of damaged central nervous system cells known as neurons.

12 Dec 2007

New model for neurodegeneration

The gradual loss of dopamine neurons is a hallmark of many neurodegenerative diseases - Parkinson's Disease chief among them.

Missing brain protein may be one of the culprits behind autism and other brain disorders

The protein helps synapses develop. Synapses--through which neurons communicate with one other-underlie our ability to learn and remember. Now Li-Huei Tsai, Picower Professor of Neuroscience at MIT, has uncovered an enzyme that is key to that protein's activity.

Scientists characterize Alzheimer's neurotoxin structure - potential new treatment approaches

Amyloid plaques, the hallmark of Alzheimer's disease, are clumps of fiber-like misfolded proteins which many experts think cause this devastating neurodegenerative disease.

Tiny fluorescent probes illuminate protein interactions in living cells

While fluorescence has long been used to tag biological molecules, a new technology developed at Yale allows researchers to use tiny fluorescent probes to rapidly detect and identify protein interactions within living cells while avoiding the biological disruption of existing methods, according to a report in Nature Chemical Biology.

Common painkillers may prevent Parkinson's disease

Researchers in the U.S. are suggesting that painkillers such as ibuprofen and naproxen can cut the risk of Parkinson's disease by as much as 60%.

Merck Serono and EPFL announce neuroscience, oncology and drug delivery partnership

Merck Serono, a division of Merck KGaA, and EPFL (Ecole Polytechnique Fédérale de Lausanne), one of the two Swiss Federal Institutes of Technology, announced the signing of a research collaboration agreement in the areas of Neuroscience, Oncology and Drug Delivery. Under this agreement, three Merck Serono-endowed Chairs will be created at EPFL: in neurodegenerative diseases, such as Alzheimer's and Parkinson's; in cancer, in the framework of the Swiss Institute for Experimental Cancer Research (ISREC); and in innovative drug delivery technologies, for instance nanoparticle vaccines.

Scientists discover new causes for neurodegeneration

Diseases that cause neurons to break-down, such as Alzheimer's, Multiple Sclerosis and Creutzfeldt-Jakob disease (Mad Cow Disease), continue to be elusive to scientists and resistant to treatments.

25 Oct 2007

The accumulation of sugar in neurons may explain the origin of several neurodegenerative diseases

A phenomenon considered healthy for cells, such as the accumulation of long chains of glucose (glycogen), which tissues store for energy purposes, is harmful for neurons.

Researcher identify specific cell that causes eye cancer, disproving long-held theory

Investigators at St. Jude Children's Research Hospital have identified the cell that gives rise to the eye cancer retinoblastoma, disproving a long-standing principle of nerve growth and development.

Researchers restore memory process in fragile X syndrome

University of California, Irvine scientists have discovered how to reverse the learning and memory problems inherent in the most common form of mental impairment.

Researchers report most complete list so far of the proteins present in the cerebral cortex

Researchers report in the October 2007 issue of Molecular & Cellular Proteomics the most complete list so far of the proteins present in the cerebral cortex – the outermost layer of the brain that plays a central role in memory, language, cognition, and consciousness.

8 Oct 2007

Loss of TDP-43 gene found to be related to age-related neurological disorders

Researchers at Mayo Clinic in Jacksonville have discovered how loss of a gene can lead to accumulation of toxic proteins in the brain, resulting in a common dementia, and they say this mechanism may be important in a number of age-related neurological disorders.

27 Sep 2007

New nanoprobe imaging station helps study the distribution of elements in cells

Scientists suspect that iron accumulation plays a role in neurodegenerative processes such as Parkinson's disease, but its distribution in neurons has never been observed because of the lack of techniques to do so. Until today.

26 Sep 2007

Process of necrosis redefined in landmark study

A new study led by investigators from the University of Pittsburgh School of Medicine demonstrates that the process of necrosis, long thought to be a chaotic, irreversible pathway to cell death, may actually be triggered as part of a regulated response to stress by a powerful protein, SRP-6, that can potentially halt necrosis in its path.

Ancient mechanism for coping with stresses also gives cancer a boost

An ancient mechanism for coping with environmental stresses, including heat and toxic exposures, also helps cancerous tumors survive, reveals a new report in the Sept. 21, 2007, issue of Cell, a publication of Cell Press.
