Molecular Markers Used to Assess Early Sciatic Nerve Injury

December 26, 2013 10:51 am | News | Comments

Substance P and calcitonin gene-related peptide are the main neuropeptides in peripheral nerve ganglia, which can anterogradely transmit nociceptive information to the central nervous system. Findings published in Neural Regeneration Research  suggest that these neuropeptides may possibly serve as an index for evaluating early peripheral nerve injury.
