Finally, inhibition from Sema3A on axon outgrowth of calcitonin gene related peptide- (CGRP-) positive sensory fibers is shown following injection of adenovirus encoding Sema3A in the spinal cord after complete spinal transection in a model of autonomic dysreflexia [88]. The gene discussed is SEMA3A; the disease is autonomic dysreflexia.
