This finding has particular importance because several neurodevelopmental disorders have recently been linked to genetic mutations in the complex developmental cascade containing Erk and its sister proteins. Researchers at the University of North Carolina at Chapel Hill have pinpointed a crucial function for a key player in the development of the nervous system. They found that this player "“ a protein called Erk "“ is necessary for nerve fibers to be wrapped with an insulating...

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...

Unlike nerves of the spinal cord, the peripheral nerves that connect our limbs and organs to the central nervous system have an astonishing ability to regenerate themselves after injury. Now, a new report in the October 1st issue of Cell, a Cell Press publication, offers new insight into how that healing process works. "We know a lot about how various cell types differentiate during development, but after a serious injury like an amputation, nerves must re-grow," said Allison Lloyd of...

Researchers at Stanford University were able to use light to induce normal patterns of muscle contraction, in a study involving bioengineered mice whose nerve-cell surfaces are coated with special light-sensitive proteins. The new approach allows scientists to more accurately reproduce muscle firing order, making it a valuable research tool. The investigators, from Stanford's Schools of Medicine and of Engineering, also believe this technique could someday spawn practical applications, from...

For these patients, immunotherapy can quickly improve symptoms A new Mayo Clinic study found that nerve inflammation may cause the pain, numbness and weakness following surgical procedures that is known as postsurgical neuropathy. The development of postsurgical neuropathies is typically attributed to compression or stretching of nerves during surgery. This new research shows that, in some cases, the neuropathy is actually caused by the immune system attacking the nerves and is...

Researchers from UCI, UCSD and Harvard deleted a cell growth inhibitor called PTEN Researchers for the first time have induced robust regeneration of nerve connections that control voluntary movement after spinal cord injury, showing the potential for new therapeutic approaches to paralysis and other motor function impairments. In a study on rodents, the UC Irvine, UC San Diego and Harvard University team achieved this breakthrough by turning back the developmental clock in a molecular...

BOSTON, Aug. 8 /PRNewswire-USNewswire/ -- Researchers for the first time have induced robust regeneration of nerve tissue connections in injured adult spinal cord sites that control voluntary movement. These findings provide hope that it may be possible to design therapies for paralysis and other impairments of motor function arising from spinal cord injury. In rodent studies, the Children's Hospital Boston, UC Irvine, and UC San Diego team made this breakthrough by turning back the...

Finding may illuminate a reason for the beneficial effects of these regimens on aging Harvard University researchers have uncovered a mechanism through which caloric restriction and exercise delay some of the debilitating effects of aging by rejuvenating connections between nerves and the muscles that they control. The research, conducted in the labs of Joshua Sanes and Jeff Lichtman and described this week in the journal Proceedings of the National Academy of Sciences, begins to explain...

Antibodies "” warrior proteins the immune system makes to defend the body against invading pathogens such as viruses and bacteria "” have a gentler side nobody knew about until now: They function not only as soldiers but also as nurses. And researchers at the Stanford University School of Medicine now think antibodies' absence in the central nervous system (the brain and spinal cord) may be a key part of the reason why nerve damage there doesn't get naturally repaired in humans....

Once damaged, nerves in the spinal cord normally cannot grow back and the only drug approved for treating these injuries does not enable nerve regrowth. Publishing online this week in the Early Edition of the Proceedings of the National Academy of Sciences, researchers at the Johns Hopkins University School of Medicine show that treating injured rat spinal cords with an enzyme, sialidase, improves nerve regrowth, motor recovery and nervous system function. "This is the first functional study...


Word of the Day
Cthulhu
  • A gigantic fictional humanoid alien god being described with a head resembling an octopus and dragon wings and claws, around whom an insane cult developed.
  • Pertaining to the mythos of Cthulhu and additional otherworldly beings created by H. P. Lovecraft or inspired by his writings and imitators.
This word was invented in 1926 by H.P. Lovecraft for his short story, 'The Call of Cthulhu.' 'Cthulhu' may be based on the word 'chthonic,' which in Greek mythology refers to the underworld.
