Lipid nanoparticles (LNPs) play a crucial role in addressing genetic disorders, and cancer, and combating pandemics such as COVID-19 and its variants. Yet, the ability of LNPs to effectively encapsulate large-size DNA molecules remains elusive. This is a significant limitation, as the successful delivery of large-size DNA holds immense potential for gene therapy. To address this gap, the present study focuses on the design of PEGylated LNPs, incorporating large-sized DNA, departing from traditional RNA and ionizable lipids. The resultant LNPs demonstrate a unique particle morphology. These particles were further engineered with a DNA coating and plasma proteins. This multicomponent bionanoconstruct exhibits enhanced transfection efficiency and safety in controlled laboratory settings and improved immune system evasion in in vivo tests. These findings provide valuable insights for the design and development of bionanoarchitectures for large-size DNA delivery, opening new avenues for transformative gene therapies. Encapsulation of large-size DNA molecules into lipid nanoparticles (LNPs) remains challenging. Here, the authors engineer PEGylated LNPs with DNA and plasma proteins to improve the delivery of large DNA molecules, enhancing the gene therapy potential. [ABSTRACT FROM AUTHOR] |
