Abstract:

Introduction: Spinal cord injury (SCI) following traumatic events is associated with the limited therapeutic options and sever complications, which can be partly due to inflammatory response. Therefore, this study aims to explore the role of inflammation in spinal cord injury. The findings showed that the pathological conditions of nervous system lead to activation of microglia, astrocyte, neutrophil, and macrophages. It is also may be mediated by glial and lead to neuronal injury and death through production of proinflammatory factors, such as cytokines (key factors in the onset, progression and suppression of inflammation) and chemokines. Inflammation is a major component of spinal cord injury; although it is possible that inflammation has beneficial effects, such as phagocytosis of apoptotic cells and pathogens clearance. However, this could contribute to spreading, amplifying, and chronicity of tissue damage, via production of neurotoxic factors. Conclusion: It seems that inflammation has a major role in the injured spinal cord. Identifying effective cells in the inflammatory responses as well as their numbers, nature of their actions, and types of released inflammatory factors, along with the discovery of appropriate coping strategies against them, will increase the hope to repair spinal cord injuries in future.

o14: cellular and molecular mechanisms of spinal cord trauma

the prevalence of spinal cord injury (sci) is about 2.5 million in the worldwide and more than 130,000 new injuries reported each year. regeneration in the cns versus the pns is very different from the other tissues and many factors can prevent regeneration in pns and specially cns. previous researches demonstrated that regeneration of cns can inhibit by inhibitory molecules and glial scar. the...

Pain management after traumatic spinal cord injury.

Pain is experienced by people suffering from spinal cord injury leading to disability and affecting the person's functional ability, independence, psychological well - being, ability to return to work and quality of life. Pain management in these patients is notoriously difficult due to multiple factors and varied mechanism leading to pain. Only few treatments have been assessed in randomized, ...

Molecular and Cellular Mechanisms of Axonal Regeneration After Spinal Cord Injury.

Following axotomy, a complex temporal and spatial coordination of molecular events enables regeneration of the peripheral nerve. In contrast, multiple intrinsic and extrinsic factors contribute to the general failure of axonal regeneration in the central nervous system. In this review, we examine the current understanding of differences in protein expression and post-translational modifications...
