The remarkable advances in molecular biology in the past decades have led to a better understanding of the mechanisms implicated in the pathophysiology of many CNS disorders as well as mechanisms that control axonal regeneration. This knowledge has raised the hope of developing new therapies that can attenuate secondary damage and maximize regeneration after injury. Our team had previously described that agents such Levetiracetam and Baclofen are able to protect the spinal cord in the acute phase of the injury. Moreover, we also demonstrated that IL-4 administration is able to modulate the inflammatory response after CNS injury and that Roflumilast promotes axonal regeneration and functional recovery after spinal cord injury. The goal of this research topic is to develop and test new molecular therapies that can heal the injured CNS. These novel therapies will focus into 3 key areas: 1) Neuroprotection, find new molecules that can modulate deleterious events such as the dysregulated immune response and excitotoxicity; 2) Neuroregeneration, tested new molecules with the ability to increase the intrinsic capacity of neurons to grow; and 3) Combinatory Approaches, find molecules that act synergistically to protect and regenerate the nervous tissue.
