Mise au Point / Update


Les traitements actuels contre la douleur chronique procurent peu d’analgésie mais d’importants effets secondaires. Une alternative serait de moduler l’activité neuronale directement à l’aide de l’optogénétique, une thérapie génique impliquant l’utilisation de protéines photo-activables. Dans les modèles animaux, cette approche diminue les douleurs inflammatoire et neuropathique. Des avancées spectaculaires permettent d’envisager son application clinique dans les prochaines décennies.

Can we use optogenetics to treat chronic pain?


The current treatments for chronic pain produce limited efficacy but severe side effects. An alternative strategy is to directly modulate neuronal activity through the use of optogenetics, a gene therapy involving photo-activatable proteins. In animal models, this approach has been shown to decrease inflammatory and neuropathic pain. Recent significant progresses allow to predict clinical applications in analgesia in the next decades.
