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®...

Neuron Transformation In The Brain Opens A New Avenue In Neurobiology

redOrbit Staff & Wire Reports - Your Universe Online A pair of Harvard University stem cell biologists have reportedly demonstrated a technique with which they can transform one type of already differentiated neuron into another. The discovery, reported by the Cambridge, Massachusetts-based Ivy League school in a statement released Sunday, demonstrates it is possible that the human brain “is not as immutable as we always thought, because at least during an early window of time...

Insect research yields insights for muscle control and nerve disorders in mammals, including humans Working with fruit flies, Johns Hopkins scientists have decoded the activity of protein signals that let certain nerve cells know when and where to branch so that they reach and connect to their correct muscle targets. The proteins´ mammalian counterparts are known to have signaling roles in immunity, nervous system and heart development, and tumor progression, suggesting broad...

Transmission of nerve signals is enhanced in the insects that eat less A novel technique for measuring tiny, rapid-fire secretions in the brains and mouthparts of fruit flies (drosophila) is providing insights into the beneficial effects of eating less – information that ultimately could help people suffering from neuromuscular disorders. Using the method, researchers uncovered never-before-seen brain chemistry that helps explain why fruit flies genetically manipulated to mimic...

In an effort to identify the underlying causes of neurological disorders that impair motor functions such as walking and breathing, UCLA researchers have developed a novel system to measure the communication between stem cell-derived motor neurons and muscle cells in a Petri dish. The study provides an important proof of principle that functional motor circuits can be created outside of the body using stem cell-derived neurons and muscle cells, and that the level of communication, or...

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...

The quest for treatments for motor neurone disease, spinal cord injury and strokes could be helped by new research that shows how key cells are produced The quest for treatments for motor neurone disease, spinal cord injury and strokes could be helped by new research that shows how key cells are produced. Scientists at the University of Edinburgh have been able to manipulate the production of motor neurones — which control all muscle activity — in zebrafish. Zebrafish are...

Some unusual alliances are necessary for you to wiggle your fingers, researchers report. Understanding those relationships should enable better treatment of neuromuscular diseases, such as myasthenia gravis, which prevent muscles from taking orders from your brain, said Dr. Lin Mei, Director of the Institute of Molecular Medicine and Genetics at Georgia Health Sciences University. During development, neurons in the spinal cord reach out to muscle fibers to form a direct line of...

Discovery could lead to treatments for muscular dystrophy and ALS Researchers at the University of Missouri have identified a communication breakdown between nerves and muscles in mice that may provide new insight into the debilitating and fatal human disease known as spinal muscular atrophy (SMA). “Critical communication occurs at the point where nerves and muscles ℠talk´ to each other. When this communication between nerves and muscles is disrupted, muscles do not...
