A Tetrahedral Framework DNA-Based Bioswitchable miR-150 Delivery System for Sepsis

Sepsis is a disease with high morbidity and mortality, for which effective treatments are lacking. In recent years, microRNAs (miRs) have been shown to regulate numerous biological processes and can function as therapeutic options for various diseases. However, the poor stability and cell entry properties of miRs have greatly limited their clinical application. In this study, we developed a tetrahedral framework nucleic acid (tFNA)-based bioswitchable miR delivery system (BiRDS) to deliver miR-150 for the treatment of sepsis. BiRDS showed anti-inflammatory effects both
