Abstract

mRNA vaccines elicit a potent immune response including antibodies and cytotoxic T cells. mRNA vaccines are currently evaluated in clinical trials for cancer immunotherapy applications, but also have great potential as prophylactic vaccines. Efficient delivery of mRNA vaccines will be key for their success and translation to the clinic. Among potential nonviral vectors, lipid nanoparticles are particularly promising. Indeed, lipid nanoparticles can be synthesized with relative ease in a scalable manner, protect the mRNA against degradation, facilitate endosomal escape, can be targeted to the desired cell type by surface decoration with ligands, and as needed, can be codelivered with adjuvants.

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

  • Modifications to the spike protein are intended to reduce the innate immune response by inhibiting proinflammatory cytokines, while the lipid nanoparticle vehicle/EV for the mRNA acts as an adjuvant to enhance the immune response.

    “Modifications to the spike protein are intended to reduce the innate immune response by inhibiting proinflammatory cytokines, while at the same time, the lipid nanoparticle vehicle/EV for the mRNA acts as an adjuvant to enhance the immune response. 194-196”

    From COVID-19, Myocarditis and Pericarditis (2023) · cites this paper as [196]

    In “Adjuvanting lipid nanoparticles,” the paper says the LNP vector can itself have an adjuvant effect and that some lipids activate the immune system. It does not support the claim about modifying the spike protein to inhibit proinflammatory cytokines; its discussion of suppressing innate immune activation concerns modified mRNA nucleotides, not spike protein. (LLM, conf=0.88)

  • Intracellular delivery of oligonucleotides can be improved by encapsulating them in lipid nanoparticles (LNP).

    “Intracellular delivery of oligonucleotides can be improved by encapsulating them in lipid nanoparticles (LNP) [9], [23]”
  • The ionizable cationic lipid contains positively charged ionizable amine groups (at low pH) to interact with the anionic mRNA during particle formation and facilitate membrane fusion during internalization.

    “The latter contains positively charged ionizable amine groups (at low pH) to interact with the anionic mRNA during particle formation and also facilitate membrane fusion during internalization (Evers et al., 2018, Reichmuth et al., 2016).”

    From mRNA-lipid nanoparticle COVID-19 vaccines: structure and stability (2021) · cites this paper as Reichmuth et al., 2016

  • With the advancement of lipid nanoparticle techniques, mRNA vaccine stability can be maintained under less rigorous settings.

    “However, with the advancement of lipid nanoparticle techniques, mRNA vaccine stability can be maintained under less rigorous settings (Reichmuth et al. 2016).”

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.
