Nanoparticles Inspired by Lung Fluid Improve Therapies Targeting Respiratory System
Researchers at CIC biomaGUNE have created pulmonary surfactant nanoparticles that encapsulate antifibrotic drugs and can be delivered by inhalation. Using a microfluidic synthesis platform, the particles achieve uniform size, high drug loading and 90% retention in mouse lungs, dramatically lowering systemic exposure. Preclinical trials demonstrated a therapeutic effect on pulmonary fibrosis, suggesting dose reductions and fewer side effects compared with oral therapies. The biomimetic design leverages native lung surfactant proteins and lipids to improve distribution and evade immune clearance.
