Recovery from chronic spinal cord contusion after Nogo receptor intervention.

OBJECTIVE Several interventions promote axonal growth and functional recovery when initiated shortly after central nervous system injury, including blockade of myelin-derived inhibitors with soluble Nogo receptor (NgR1, RTN4R) decoy protein. We examined the efficacy of this intervention in the much more prevalent and refractory condition of chronic spinal cord injury. METHODS We eliminated th...

Thermostabilized chondroitinase ABC Promotes Neuroprotection after Contusion Spinal Cord Injury

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....

Sialidase enhances recovery from spinal cord contusion injury.

Axons fail to regenerate in the injured spinal cord, limiting motor and autonomic recovery and contributing to long-term morbidity. Endogenous inhibitors, including those on residual myelin, contribute to regeneration failure. One inhibitor, myelin-associated glycoprotein (MAG), binds to sialoglycans and other receptors on axons. MAG inhibition of axon outgrowth in some neurons is reversed by t...

Delayed systemic Nogo-66 receptor antagonist promotes recovery from spinal cord injury.

Traumatized axons possess an extremely limited ability to regenerate within the adult mammalian CNS. The myelin-derived axon outgrowth inhibitors Nogo, oligodendrocyte-myelin glycoprotein, and myelin-associated glycoprotein, all bind to an axonal Nogo-66 receptor (NgR) and at least partially account for this lack of CNS repair. Although the intrathecal application of an NgR competitive antagoni...

Functional recovery assessment of spinal cord contusion model in male rats without therapeutic interventions

Introduction: Spinal cord injury (SCI) is one of the most serious clinical diseases, which not only affects the patient's physical and mental status, but its effects will be spread to family and community. After severe spinal cord injury, astrocytes of the central nervous system (CNS) become reactive astrocytes, and play the main role of glial scar formation. The scar is a major obstacle to r...
