Transcriptome of dorsal root ganglia caudal to a spinal cord injury with modulated behavioral activity


ABSTRACT: Spinal cord injury (SCI) is a devastating clinical condition resulting in significant disabilities for affected individuals. Apart from local injury within the spinal cord, SCI patients develop a myriad of complications characterized by multi-organ dysfunction. Some of the dysfunctions are directly related to the disrupted integrity of sensory afferents from DRGs, which signal to both the spinal cord and peripheral organs. Some classes of DRG neurons undergo axonal sprouting both peripherally and centrally after spinal cord injury. Such physiological and anatomical re-organization of afferent axons after SCI contributes to both adaptive and maladaptive plasticity, which may be modulated by activity/exercise. In this study, we collected comprehensive gene expression data in whole dorsal root ganglia (DRGs) throughout the levels below the injury comparing the effects of SCI with and without activity/exercise.
