A molecule responsible for the proper formation and function of neurons finds its way to the right place not because it is actively recruited, but because it can't go anywhere else. Researchers at Baylor College of Medicine have identified a distal axonal cytoskeleton that functions as a boundary to ensure a key scaffolding protein, called ankyrinG, stays at the start of the axon near the cell body where it performs its functions of clustering sodium and potassium ion channels and...

New research from the University of North Carolina at Chapel Hill School of Medicine describes a key molecular mechanism in nerve fibers that ensures the rapid conductance of nervous system impulses. New research from the University of North Carolina at Chapel Hill School of Medicine describes a key molecular mechanism in nerve fibers that ensures the rapid conductance of nervous system impulses. The findings appear online Jan. 27, 2011 in the journal Neuron. Our hard-wired nerve fibers or...

New study about 'helper' cells has implications for nerve disorders such as multiple sclerosis Glial cells, which help neurons communicate with each other, can leave the central nervous system and cross into the peripheral nervous system to compensate for missing cells, according to new research in the Dec. 2 issue of The Journal of Neuroscience. The animal study contributes to researchers' basic understanding of how the two nervous systems develop and are maintained, which is essential for...

In the July issue of Biomaterials, published by Elsevier, researchers from the University of Central Florida (UCF) report on the first lab-grown motor nerves that are insulated and organized just like they are in the human body. The model system will drastically improve understanding of the causes of myelin-related conditions, such as diabetic neuropathy and later, possibly multiple sclerosis (MS). In addition, the model system will enable the discovery and testing of new drug therapies for...

Multiple sclerosis, diabetic neuropathy, and other conditions caused by a loss of myelin insulation around nerves can be debilitating and even deadly, but adequate treatments do not yet exist. That's in large part because of deficiencies in model research systems. In an upcoming issue of the journal Biomaterials, a UCF team addresses this problem with a report on the first lab-grown motor nerves that are insulated and organized the same way they are in the body. The group's model system,...


Word of the Day
barratry
  • The offense of persistently instigating lawsuits, typically groundless ones.
  • An unlawful breach of duty on the part of a ship's master or crew resulting in injury to the ship's owner.
  • Sale or purchase of positions in church or state.
This word ultimately comes from the Old French word 'barater,' to cheat.
