Retinoic acid (RA) promotes growth and differentiation in many developing tissues but less is known about its influence on CNS regeneration. We investigated the possible involvement of RA in rat spinal cord injury (SCI) using the New York University (NYU) impactor to induce mild or moderate spinal cord contusion injury. Changes in RA at the lesion site were(More)
Reliable animal models of traumatic brain injury (TBI) are essential to test novel hypotheses and therapeutic interventions. In this study, based on advantages of both the closed head injury (CHI) and controlled cortical impact (CCI) models, we developed a bilateral head injury model in mice. C57BL/6 mice were used in this study. A midline craniotomy (5mm(More)
This study investigated whether neuronal inhibitor of DNA binding 2 (Id2), a regulator of basic helix-loop-helix (bHLH) transcription factors, can activate the intrinsic neuritogenetic mode of dorsal root ganglion (DRG) neurons in adult mice following spinal cord injury (SCI). First, the Id2 developmental expression profile of DRG neurons, along with the(More)
Animal models of traumatic brain injury (TBI) are essential for testing novel hypotheses and therapeutic interventions. Unfortunately, due to the broad heterogeneity of TBI in humans, no single model has been able to reproduce the entire spectrum of these injuries. The controlled cortical impact (CCI) model is one of the most commonly used models of(More)
Atrophy of upper motor neurons hampers axonal regeneration and functional recovery following spinal cord injury (SCI). Apart from the severity of primary injury, a series of secondary pathological damages including spinal cord edema and glial scar formation affect the fate of injured upper motor neurons. The aquaporin-4 (AQP4) water channel plays a critical(More)
