Abstract

Immunomodulatory function of all-trans retinoic acid (ATRA) has been gathering much attention for the therapy of autoimmune diseases. ATRA is a chemically unstable molecule which requires proper formulation for targeted delivery. Here we examined nanostructured lipid carrier (NLC) for the formulation of ATRA. NLC is a representative nanoparticle formulation especially suited for oral delivery. We established the preparation procedures of ATRA-containing NLC (NLC-RA) which minimizes the degradation of ATRA during the preparation process. NLC-RA thus obtained was taken up by macrophages and induced anti-inflammatory response via suppressing NF-κB signaling as well as via enhancing the production of anti-inflammatory cytokines. Moreover, NLC-RA enhanced differentiation of naïve T cells to regulatory T cells in the co-culture system with dendritic cells. These results suggest that NLC-RA is a promising alternative therapy for the autoimmune diseases especially intestinal bowel disease.

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?

  • RA formulations are taken up by macrophages and induce anti-inflammatory responses by suppressing NF-kB signaling and increasing bone morphogenetic protein 2 signaling, as well as by enhancing the production of anti-inflammatory cytokines (e.g., IL-10).

    “RA formulations are taken up by macrophages and induce anti-inflammatory responses by suppressing NF-kB signaling and increasing bone morphogenetic protein 2 signaling (pivotal for bone and cartilage development), as well as by enhancing the production of anti-inflammatory cytokines (e.g., IL-10)58,124.”
  • RA formulations have the capacity to enhance the differentiation of naïve T cells to regulatory T cells.

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.
