Formulazione di un sistema di trasporto di esosomi caricato con dopamina

Executive Industry Relevance

This method enables the formulation of dopamine-loaded exosomes, offering a neurotherapeutic delivery strategy that enhances payload encapsulation through saponin-induced membrane permeabilization. It supports early-stage target validation by providing a reproducible system to interrogate dopamine delivery mechanisms in disease-relevant models. The approach contributes to mechanistic de-risking in preclinical development by standardizing exosome-based carrier preparation for neurotherapeutic screening.
