A novel therapeutic strategy for cartilage diseases based on lipid nanoparticle-RNAi delivery system

Background Cartilage degeneration affects millions of people but preventing its degeneration is a big challenge. Although RNA interference (RNAi) has been used in human trials via silencing specific genes, the cartilage RNAi has not been possible to date because the cartilage is an avascular and very dense tissue with very low permeability.
