초록/해제  
요약The past decade has witnessed an explosive growth of RNA therapeutics, as evident by FDA's approval of Onpattro (Alnylam) in 2018, Comirnaty (BioNTech/Pfizer) and Spikevax (Moderna) in 2022. The excitement toward this relatively new type of therapeutic modality has triggered much more research and development in the pipeline, spanning a variety of indications such as infectious diseases, cancer immunotherapy, genome editing, and neurodegenerative diseases. Despite their great promises, delivery of RNA has emerged as the central challenge for many of the developments, as naked oligonucleotides have limited capacity to get across cellular membranes and elicit their functions in the cytosol. My PhD work aims to address this challenge by developing new generations of transporters that could deliver oligonucleotides with high efficiency, selectivity, and tolerability.In this dissertation, Chapter 1 provides an overview on the design criteria and strategies for existing and future RNA transporters. Chapter 2 describes the design and development of Charge-Altering Releasable Transporters furnished with beta-amido carbonate backbones (bAC CARTs), which showed significantly improved mRNA delivery to T cells in vitro and in vivo. Chapter 3 presents CARTs employed with guanidinylated serinol moieties (GSer-CARTs). GSer-CARTs reveal a novel chemical mechanism for guanidinium groups to undergo O-to-N acyl shift reactions. The transporters delivered mRNA efficiently to lungs and spleens with high selectivity. GSer-CART/circular RNA formulations have also shown promise in cancer vaccination. Chapter 4 introduces a novel delivery system called Discrete Immolative Guanidinium Transporters (DIGITs), which unlike CARTs, are discrete moieties and enable selective delivery of RNA to peripheral blood cells.
