Alan McStravick for redOrbit.com - Your Universe Online We have all experienced it. While enjoying a delicious meal, the flavors and textures of food are delightful as we practice the mastication necessary for the beginning of the digestive process. Then, out of nowhere, our tongue fails to get out of the way of our teeth and we clamp down on the fleshy muscle, eliciting pain and, almost certainly, a few choice words. Thankfully this situation occurs with relative infrequency and, thanks...

A new way to artificially control muscles using light, with the potential to restore function to muscles paralyzed by conditions such as motor neuron disease and spinal cord injury, has been developed by scientists at UCL and King’s College London. The technique involves transplanting specially-designed motor neurons created from stem cells into injured nerve branches. These motor neurons are designed to react to pulses of blue light, allowing scientists to fine-tune muscle control by...

Zebrafish study connects data between fish and mammalian locomotion We might have more in common with a lamprey than we think, according to a new Northwestern University study on locomotion. At its core, the study of transparent zebrafish addresses a fundamental evolution issue: How did we get here? Neuroscientists Martha W. Bagnall and David L. McLean have found that the spinal cord circuits that produce body bending in swimming fish are more complicated than previously thought....

Brain's elusive motor neurons are dressed in fluorescence so scientists can find them and study why they die A small group of elusive neurons in the brain's cortex play a big role in ALS (amyotrophic lateral sclerosis), a swift and fatal neurodegenerative disease that paralyzes its victims. But the neurons have always been difficult to study because there are so few of them and they look so similar to other neurons in the cortex. In a new preclinical study, a Northwestern Medicine®...

Spinal muscular atrophy (SMA) is an incurable, and progressive, disease caused by an inheritable defect in the gene SMN1. Depending on the severity of the mutation it can result in the loss of spinal cord motor neurons, muscle wasting (atrophy) and even death of an affected child. A new study published in Biomed Central's open access journal BMC Medicine shows that Fasudil, a ROCK inhibitor, can improve both the size of muscle fibers and their connection to motor neurons. Fasudil also...

Among stem cell biologists there are few better-known proteins than nestin, whose very presence in an immature cell identifies it as a "stem cell," such as a neural stem cell. As helpful as this is to researchers, until now no one knew which purpose nestin serves in a cell. In a study published in the Jan. 30, 2011, advance online edition of Nature Neuroscience, Salk Institute of Biological Studies investigators led by Kuo-Fen Lee, PhD., show that nestin has reason for being in a completely...

A team of researchers, led by Scott Oakes, at the University of California, San Francisco, has identified a way to prevent symptom onset, weight loss, and paralysis and extend survival in a mouse model of amyotrophic lateral sclerosis (ALS; also known as Lou Gehrig's disease), providing a new avenue of research for the development of therapeutics for ALS and other motor neuron diseases. ALS and other motor neuron diseases are neurological disorders that selectively affect nerve cells that...

Discovery could help scientists develop new treatments for motor neuron diseases In a surprising and unexpected discovery, scientists at NYU Langone Medical Center have found that a single type of gene acts as a master organizer of motor neurons in the spinal cord. The finding, published in the September 9, 2010 issue of Neuron, could help scientists develop new treatments for diseases such as Lou Gehrig's disease or spinal cord injury. The "master organizer" is a member of the Hox family of...

Scientists have devised a method for coaxing mouse embryonic stem cells into forming a highly specific motor neuron subtype. The research, published by Cell Press in the September 3rd issue of the journal Cell Stem Cell, provides new insight into motor neuron differentiation and may prove useful for devising and testing future therapies for motor neuron diseases. Motor neurons in the spinal cord communicate with other neurons in the central nervous system and send long projections out to...

Johns Hopkins Neuroscientists Discover New Molecular Control Researchers at the Johns Hopkins School of Medicine have discovered how one antioxidant protein controls the activity of another protein, critical for the development of spinal cord neurons. The research, publishing this week in Cell, describes a never-before known mechanism of protein control. "This is the first time we've seen this type of chemical reaction control neuronal differentiation," says Shanthini Sockanathan, Ph.D., an...
