Abstract

Therapeutic mRNA vaccination is an attractive approach to trigger antitumor immunity. However, the mRNA delivery technology for customized tumor vaccine is still limited. In this work, bacteria‐derived outer membrane vesicles (OMVs) are employed as an mRNA delivery platform by genetically engineering with surface decoration of RNA binding protein, L7Ae, and lysosomal escape protein, listeriolysin O (OMV‐LL). OMV‐LL can rapidly adsorb box C/D sequence‐labelled mRNA antigens through L7Ae binding (OMV‐LL‐mRNA) and deliver them into dendritic cells (DCs), following by the cross‐presentation via listeriolysin O‐mediated endosomal escape. OMV‐LL‐mRNA significantly inhibits melanoma progression and elicits 37.5% complete regression in a colon cancer model. OMV‐LL‐mRNA induces a long‐term immune memory and protects the mice from tumor challenge after 60 days. In summary, this platform provides a delivery technology distinct from lipid nanoparticles (LNPs) for personalized mRNA tumor vaccination, and with a “Plug‐and‐Display” strategy that enables its versatile application in mRNA vaccines.

Claims the paper makes

This paper’s full text isn’t openly available, so its claims and self-check weren’t run. The registry and citation checks still apply.

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?

  • Mizrak et al. engineered genetically modified exosomes from HEK-293 carrying mRNA/protein encoding CD and UPRT to treat schwannomas; CD converted prodrug 5-FC into active form 5-FU, inhibiting DNA synthesis and leading to apoptosis of cancer cells.

    “The study revealed that CD converted the prodrug (5-FC) into its active form (5-FU), and consequentially, the DNA synthesis was inhibited, leading to the apoptosis of cancer cells [122].”
  • Target killing was achieved by HchrR6-induced conversion of prodrug CNOB into active drug MCHB in tumors.

    “The target killing was achieved by HchrR6-induced conversion of prodrug CNOB into active drug 9-p amino-6-chloro-5H-benzo[a]phenoxazine-5-one (MCHB) in tumors [122].”
  • Exosomes derived from dendritic cells and HEK-293 loaded with mRNA encoding HChrR6 exhibited selective killing and almost complete suppression of breast cancer in a mouse model.

    “When the designed exosomes were delivered to HER2 + human breast cancer cells, they exhibited selective killing and almost complete suppression of breast cancer in a mouse model.”

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.
