Selective organ targeting (SORT) nanoparticles for tissue-specific mRNA delivery and CRISPR-Cas gene editing.

ABSTRACT: CRISPR-Cas gene editing and messenger RNA-based protein replacement therapy hold tremendous potential to effectively treat disease-causing mutations with diverse cellular origin. However, it is currently impossible to rationally design nanoparticles that selectively target specific tissues. Here, we report a strategy termed selective organ targeting (SORT) wherein multiple classes of lipid nanoparticles are systematically engineered to exclusively edit extrahepatic tissues via addition of a supplemental SORT molecule. Lung-, spleen- and liver-targeted SORT lipid nanoparticles were designed to selectively edit therapeutically relevant cell types including epithelial cells, endothelial cells, B cells, T cells and hepatocytes. SORT is compatible with multiple gene editing techniques, includin
