Partial injury to the spinal cord can propagate itself, sometimes leading to paralysis attributable to degeneration of initially undamaged neurons. We demonstrated recently that autoimmune T cells directed against the CNS antigen myelin basic protein (MBP) reduce degeneration after optic nerve crush injury in rats. Here we show that not only transfer of T cells but also active immunization with...
Behavioral hypersensitivity is common following spinal cord injury (SCI), producing significant discomfort and often developing into chronic pain syndromes. While the mechanisms underlying the development of behavioral hypersensitivity after SCI are poorly understood, previous studies of SCI contusion have shown an increase in amino acids, namely, aspartate and glutamate, along with a decrease ...
Background: Chondroitinase ABC (cABC), due to its loosening impact on the extracellular matrix scaffold, has been used to enhance regeneration of injured axonal tracts after spinal cord injury (SCI). However, cABC thermal instability at physiological temperature has limited its clinical application. The disaccharide trehalose has been shown to increase the stability of cABC in body temperature....
Primary damage to the blood-spinal cord barrier (BSCB) is a nearly universal consequence of spinal cord injury that contributes significantly to the overall pathology. We have characterized quantitatively the extent and severity of primary, physical disruption of the BSCB in adult rats five minutes and fifteen minutes after graded trauma induced with the Impactor weight drop model of spinal cor...
We have completed the first large-scale gene expression study of acute spinal cord injury (SCI) in rat. Oligonucleotide microarrays containing 1,200 gene-specific probes were used to quantify mRNA levels, relative to uninjured controls, in spinal cords injured using a standard contusion model. Our results revealed a marked loss of neuron-specific mRNAs at the injury site. The surviving cells sh...
Introduction: Spinal cord injuries (SCI) lead to permanent irreversible functional deficits. Poor prognosis of patients is the motivation of searching a treatment for the chronic injury. Planting stem cells provides us with a promising strategy. In the meanwhile, the use of olfactory ensheathing cells (OECs) has shown very good results. This study aims at evaluating the effe...
