Calcitonin gene-related peptide in anterior and posterior horns of spinal cord after brachial plexus injury*

The expression and role of CGRP are in discrepancy in the anterior and posterior horns of spinal cord after brachial plexus injury. The CGRP in anterior horn of spinal cord are derived from the cell body of motor neurons, and may be involved in the repairing mechanism of nerve injury regeneration; Whereas those in the posterior horn are mainly derived from posterior root ganglion, and may be associated with the conduction of noxious stimulations.
