Background: Traumatic brain injury (TBI) induces significant cognitive deficits correlated with white matter injury, involving both axonal and myelin damage. Several models of TBI ex vivo are available to mimic focal impact on brain tissue. However, none of them addressed the study of trauma-induced myelin damage.

Article Synopsis
  • Remyelination is when the body tries to repair the protective covering (myelin) around nerve cells in the brain, which doesn’t always work well, especially in certain diseases.
  • Scientists studied a protein called sAPPα, which might help in repairing this myelin when they used a special drug called etazolate, on mice that had nerve damage.
  • Their results showed that etazolate could help restore myelin and protect nerve cells, making it a promising way to help with brain injuries caused by myelin loss.

Traumatic brain injury (TBI) evokes an intense neuroinflammatory reaction that is essentially mediated by activated microglia and that has been reported to act as a secondary injury mechanism that further promotes neuronal death. It involves the excessive production of inflammatory cytokines and the diminution of neuroprotective and neurotrophic factors, such as the soluble form alpha of the amyloid precursor protein (sAPPα), generated by the activity of α-secretases. Hence, the aim of this study was to examine the effects of etazolate, an α-secretase activator, on acute and belated post-TBI consequences.

Comorbidity of cognitive and stress disorders is a common clinical sequel of traumatic brain injury (TBI) that is essentially determined by the site and severity of the insult, but also by the extent of the ensuing neuroinflammatory response. The present study sought to examine the late effects of closed-head TBI on memory function and anxiety in mice, in order to further examine the potential efficacy of an acute anti-inflammatory treatment with minocycline. The mouse model of closed-head injury by mechanical percussion was applied on anesthetized Swiss mice.
