Article Title: Development of an iPSC-derived immunocompetent skin model for identification of skin sensitizing substances

doi: 10.1177/20417314251336296

Figure Lengend Snippet: Functional and molecular characterization of iPSC-derived dendritic cells (iPSC-DC). (a and b) Phase-contrast microscopy images demonstrate distinct morphology. iPSC-DC display characteristic dendritic projections, while iPSC exhibit tightly packed colonies with a high nucleus-to-cytoplasm ratio and well-defined colony borders (magnification 20×). (c and d) iPSC-DC and iPSC were stained with fluorochrome-conjugated antibodies against HLA-DR, CD209, CD11c, CD86, and CD83. Unstained controls are shown in red histograms. (e) Relative IL-8 secretion of iPSC and iPSC-DC treated with a positive control composed of 50 ng/mL tumor necrosis factor-alpha (TNF-α) and 50 ng/mL interleukin-1 beta (IL-1β) in comparison to their untreated controls. (f) Western blot analysis of iPSC and iPSC-DC for the pluripotency marker Lin28a and the DC-markers CD11c and CD209, β-Actin was used as a loading control. (g) Mixed Lymphocyte Reaction Assay to assess antigen-presenting function of mature iPSC-DC: Mature iPSC-DC were co-cultured with 1 × 10 CFSE-labeled allogeneic CD4+ T cells at a DC:T cell ratio of 1:25. After 5 days of co-culture, proliferation of CD4+ CFSE-labeled T cells was analyzed by flow cytometry ( N = 3–6). T cells cultured without DC, either with or without CD3/CD28 T cell activator, served as negative and positive controls, respectively. Mature DC treated with DNCB (positive control) significantly induced the proliferation of allogeneic T cells, demonstrating their functional antigen-presenting capability. Statistical analysis was performed using one-way ANOVA with Dunnett’s correction. ** p -value ⩽ 0.01, ns: not significant. Data are presented as mean ± SD. ( N = 3–6).

Article Snippet: Following primary antibody incubation, membranes were washed with a TBS-T buffer (tris-buffered saline with Tween) and incubated for 1 h at room temperature with horseradish peroxidase (HRP)-conjugated secondary antibodies: anti-mouse (Cell Signaling Technology, Frankfurt/Main, Germany) for Lin28a and CD209, and anti-rabbit (Cell Signaling Technology, Frankfurt/Main, Germany) for CD11c.

RSV inhibits Lin28A mRNA expression in NCCIT cells, potentially through inhibiting Lin28A mRNA synthesis via the decrease in the transcription factors SP1 and STAT3; however, this has not been completely proven in the model. Conversely, it was revealed that RSV inhibits the expression of the USP28 deubiquitinase and the MAPK/ERK pathway, which is responsible for phosphorylation at serine 200, which allows its stability. This causes the Lin28A protein to lose its stability mechanisms and begin its degradation through the proteasomal pathway. Image produced in Biorender.
