Abstract

Visualization of the spatio-temporal trafficking of vaccines after their delivery would help evaluate the efficacy of candidate formulations and aid their rational design for preclinical and translational studies. Here, we show that a dual radionuclide-near-infrared probe allows for quantitative, longitudinal and non-invasive monitoring, via positron emission tomography-computed tomography and near-infrared imaging of cynomolgus macaques, of the trafficking dynamics to draining lymph nodes of a model messenger RNA vaccine labelled with the probe. After intramuscular administration of the vaccine to the monkeys, we observed the dynamics of the mRNA vaccine at the injection site and in the draining lymph nodes, performed cellular analyses of the involved tissues using flow cytometry and identified through immunofluorescence that professional antigen-presenting cells are the primary cells containing the injected mRNA and encoding the antigen. This approach may reveal spatio-temporal determinants of vaccine efficacy in preclinical and translational studies employing large mammals.

  • A yellow fever mRNA vaccine delivered by LNP was mainly expressed at the injection site as well as in draining lymph nodes in cynomolgus macaques.

    “A recent study has shown that a yellow fever mRNA vaccine delivered by LNP was mainly expressed at the injection site as well as in draining lymph nodes in cynomolgus macaques (Lindsay et al., 2019).”

  • Owing to their relatively small size, neutral surface charge and diffusible PEG lipid coating, mRNA LNPs might also enter the lymphatics to directly target lymph-node-resident antigen-presenting cells and B cells.

    “owing to their relatively small size (~100 nm), neutral surface charge and diffusible PEG lipid coating, mRNA LNPs might also enter the lymphatics to directly target LN-resident APCs and B cells [11,58]”

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.
