Développement d’un modèle de pression translaminaire à l’aide d’un système autonome translaminaire

Executive Industry Relevance

This method enables mechanistic de-risking of retinal ganglion cell targets by simulating physiologically relevant translaminar pressure conditions. It supports target validation in glaucoma research by providing a disease-relevant system for assessing functional responses under controlled pressure differentials. The approach enhances predictive confidence in preclinical models by isolating pressure as an independent variable in visual pathway signaling studies.
