摘要
Neuropathic pain remains poorly treated, with most new drugs falling through the translational gap. The traditional model of bench-to-bedside research has relied on identifying new mechanisms/targets in animal models and then developing clinical applications. Several have advocated bridging the translational gap by beginning with clinical observations and back-translating to animal models for further investigation of mechanisms. There is good evidence that phenotyping of patients through quantitative sensory testing can lead to improved treatment selection and hence improved patient outcomes. This practice has been widely adopted in clinical investigations, but its application in preclinical research is not mainstream. In this review, we retrospectively examine our historical rodent data sets with the aim of reconsidering drug effects on sensory neuronal endpoints, their alignment with clinical observations, and how these might guide future clinical studies. RESUME La douleur neuropathique reste mal traitee, alors que la plupart des nouveaux medicaments ne reussissent pas a franchir le fosse translationnel. Le modele traditionnel de la recherche, du laboratoire au chevet du patient, repose sur l'identification de nouveaux mecanismes ou cibles dans des modeles animaux, suivie du developpement d'applications cliniques. Certains preconisent de combler le fosse de la recherche translationnelle en commencant par des observations cliniques et en les transposant ensuite sur des modeles animaux afin d'approfondir l'etude des mecanismes. Il est bien etabli que le phenotypage des patients par des tests sensoriels quantitatifs peut conduire a une meilleure selection des traitements et, par consequent, a de meilleurs resultats pour les patients. Ces pratiques ont ete largement adoptees dans les enquetes cliniques, mais leur application dans la recherche preclinique n'est pas generalisee. Dans cette revue, nous examinons retrospectivement nos ensembles de donnees historiques sur les rongeurs dans le but de reconsiderer les effets des medicaments sur les parametres neuronaux sensoriels, leur alignement avec les observations cliniques et la maniere dont celles-ci pourraient orienter les etudes cliniques futures.
