New Chemical Compound Shows Promise In Restoring Function

Case Western Reserve scientists have developed a new chemical compound that shows extraordinary promise in restoring function lost to spinal cord injury. The compound, which the researchers dubbed intracellular sigma peptide (ISP), allowed paralyzed muscles to activate in more than 80 percent of the animals tested. The remarkable study, partly funded by the National Institutes of Health, appears in the December 3 edition of the journal Nature.

Case Western Reserve University School of Medicine Professor of Neurosciences Jerry Silver, PhD, the senior author, led an international team of scientists in the research in which 21 of 26 animals with spinal cord injury regained the ability to urinate, move or both. In the experiments, the peptide appears to allow nerve fibers to overcome scarring that normally blocks their regrowth.
