Abstract

To improve the efficiency of orally delivered vaccines, PEGylated PLGA-based nanoparticles displaying RGD molecules at their surface were designed to target human M cells. RGD grafting was performed by an original method called "photografting" which covalently linked RGD peptides mainly on the PEG moiety of the PCL-PEG, included in the formulation. First, three non-targeted formulations with size and zeta potential adapted to M cell uptake and stable in gastro-intestinal fluids, were developed. Their transport by an in vitro model of the human Follicle associated epithelium (co-cultures) was largely increased as compared to mono-cultures (Caco-2 cells). RGD-labelling of nanoparticles significantly increased their transport by co-cultures, due to interactions between the RGD ligand and the beta(1) intregrins detected at the apical surface of co-cultures. In vivo studies demonstrated that RGD-labelled nanoparticles particularly concentrated in M cells. Finally, ovalbumin-loaded nanoparticles were orally administrated to mice and induced an IgG response, attesting antigen ability to elicit an immune response after oral delivery.

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?

  • Very low IL-4 and significantly higher IFN-γ production by spleen cells was observed in animals immunized with particles compared with mice fed unprotected OVA, and this was more pronounced when β1 integrin on M cells was targeted by an RGD-containing peptide.

    “Moreover, very low IL-4 and significantly higher IFN-γ production of spleen cells was observed in animals immunized with particles compared with mice being fed unprotected OVA, which was even more pronounced when the β1 integrin on M cells was specifically targeted by an RGD-containing peptide [76].”
  • Encapsulation of antigens into PLGA particles both protects from GI digestion and initiates specific immune responses through IgG and IFN-γ production at very low antigen amounts.

    “Recently, it was observed that the encapsulation of antigens into PLGA particles did not only protect from GI digestion, but also initiated specific immune responses by the means of IgG and IFN-γ production at very low antigen amounts [76].”

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.
