T cell-specific non-viral DNA delivery and in vivo CAR-T generation using targeted lipid nanoparticles

Abstract

Our findings demonstrate for the first time that targeted LNPs can be employed for efficient DNA delivery to T cells in vitro and in vivo. We show that when combined with transposase technology, this LNP-based system can efficiently generate stable CAR-T cells directly in vivo, inducing potent and durable antitumor responses. NCtx represents a novel non-viral gene therapy vector for in vivo CAR-T therapy, offering a scalable and potentially more accessible alternative to traditional approaches in CAR-T cell generation.
