Abstract

Systemic delivery of mRNA-based therapeutics remains a challenging issue for preclinical and clinical studies. Here, we describe new lipid-like nanoparticles (TT-LLNs) developed through an orthogonal array design, which demonstrates improved delivery efficiency of mRNA encoding luciferase in vitro by over 350-fold with significantly reduced experimental workload. One optimized TT3 LLN, termed O-TT3 LLNs, was able to restore the human factor IX (hFIX) level to normal physiological values in FIX-knockout mice. Consequently, these mRNA based nanomaterials merit further development for therapeutic applications.

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

  • Increasing the ionizable lipid molar ratio in an LNP formulation can augment mRNA delivery.

    “In our prior studies, we found that the increase in ionizable lipid molar ratio in the LNP formulation can augment mRNA delivery44.”

    From Blood–brain-barrier-crossing lipid nanoparticles for mRNA delivery to the central nervous system (2025) · cites this paper as [44]

    In the formulation-optimization passage (labeled Abstract; page unavailable), the paper says that reduced levels of the lipid-like component TT3 may facilitate mRNA delivery and describes decreasing its ratio from 40 to 10. It does not report increased delivery from increasing the TT3 ratio; its reported trend runs in the opposite direction. (LLM, conf=0.84)

    Checked by a reasoning model — may be wrong.

  • mRNA-based protein replacement therapies have been applied to haematological diseases, central nervous system disorders, skin diseases and hearing loss in preclinical studies.

    “In addition, mRNA-based protein replacement therapies have been applied to haematological diseases (for example, haemophilia A232, haemophilia B91,104,233 and thrombotic thrombocytopaenic purpura234), central nervous system disorders67,152 (for example, Friedreich’s ataxia67), skin diseases235,236 (for example, elastin deficiency235) and hearing loss237 in preclinical”

  • After 6 hours of i.v. injection of TT3-delivered hFIX mRNA, plasma FIX concentration was 1740 ng/mL and activity was 791 mIU/mL, within normal physiological values.

    “After 6 hours of i.v. injection, the plasma concentration of FIX was 1740 ng/mL and the activity was 791 mIU/mL, which were well within the normal physiological values.[40]”

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.
