Extrahepatic delivery is advancing through ligand-targeted LNPs, peptide conjugates, and engineered exosomes. AI-enhanced design is accelerating optimization of RNA sequences, chemistries, and vectors.
Validation breadth across biological contexts is still narrow. No canonical validation observations are stored yet, so context-specific performance remains under-specified.
