Abstract

Developing safe and efficient non-viral delivery systems remains a major challenge for in vivo applications of gene therapy, especially in cystic fibrosis. Unlike conventional cationic polymers or lipids, the emerging poloxamine-based copolymers display promising in vivo gene delivery capabilities. However, poloxamines are invalid for in vitro applications and their in vivo transfection efficiency is still low compared with viral vectors. Here, we show that peptides developed by modular design approaches can spontaneously form compact and monodisperse nanoparticles with poloxamines and nucleic acids via self-assembly. Both messenger RNA and plasmid DNA expression mediated by peptide-poloxamine nanoparticles are greatly boosted in vitro and in the lungs of cystic fibrosis mice with negligible toxicity. Peptide-poloxamine nanoparticles containing integrating vectors enable successful in vitro and in vivo long-term restoration of cystic fibrosis transmembrane conductance regulator deficiency with a safe integration profile. Our dataset provides a new framework for designing non-viral gene delivery systems qualified for in vivo genetic modifications.

Claims other papers make about this one

Each is checked against this paper’s own text: does it say what the citing paper says it does?

  • After three-time i.t. administration of peptide-poloxamine nanoparticles containing the Sleeping Beauty transposon system, CFTR expression lasted for 18 weeks in CF mice and the level was similar to that of the wild type group.

    “After three-time i.t. administration, CFTR expression lasted for 18 weeks in CF mice and the level was similar to that of the wild type group.”
  • Lung pathohistological sections indicated no visible signs of inflammatory infiltrates and blood sample analysis showed a normal level of white blood cells after treatment.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
