Team apply new procedure to rapidly induce nerve regeneration in mammals
American scientists believe a new procedure to repair severed nerves could result in patients recovering in days or weeks, rather than months or years. The team used a cellular mechanism similar to that used by many invertebrates to repair damage to nerve axons. Their results are published today in the Journal of Neuroscience Research.

Over the last years, two teams of researchers at The Scripps Research Institute have steadily built a model of how a powerful DNA repair complex works. Now, their latest discovery provides revolutionary insights into the way the molecular motor inside the complex functions – findings they say may have implications for treatment of disorders ranging from cancer to cystic fibrosis.
In a paper published in an Advance Online Edition of Nature Structural and Molecular Biology March 27, 2011, the scientists say that the complex’s motor molecule, known as Rad50, is a surprisingly flexible protein that can change shape and even rotate depending on the task at hand.
