Figure Lengend Snippet: Multiplexed ELISA of conditioned media from unstimulated umbilical artery (HUAEC), umbilical vein (HUVEC), dermal microvascular (HDMEC), and pulmonary microvascular (HPMEC) endothelial cells. Conditioned media was collected from 1 well per cell type after 16 hours incubation. Samples were analyzed with a Luminex Magpix device and a custom ProcartaPlex inflammation panel. Data are represented as (A) Heatmap normalized across the range for each protein, with darker tones corresponding to higher expression and less expression for lighter tones. Factors that measured below the limit of detection are indicated with an X. (B) log 10 (average expression) ± SEM for N=4 independent experiments. Factors that measured below the limit of detection are indicated with an X. Full statistical analysis with one-way ANOVA and Tukey-Kramer pairwise comparisons testing was done for average expression across all cell types, with results presented in Supplemental Figure 1.

Figure Lengend Snippet: Multiplexed ELISA of conditioned media from TNF-stimulated (50ng/mL TNF in media) umbilical artery (HUAEC), umbilical vein (HUVEC), dermal microvascular (HDMEC), and pulmonary microvascular (HPMEC) endothelial cells. Conditioned media was collected from 1 well per cell type after 16 hours incubation. Samples were analyzed with a Luminex Magpix device and a custom ProcartaPlex inflammation panel. (A) Heatmap normalized across the range for each protein, with darker tones corresponding to higher expression and less expression for lighter tones. (B) Fold-change expression differences from unstimulated control for factors with >8 fold increase by at least one cell type. Data are average fold change-expression for N=4 independent experiments. One-way ANOVA with Tukey-Kramer pairwise comparisons testing was done for each condition, with asterisks indicating statistical significance between conditions (*p<0.05).

Figure Lengend Snippet: Endothelial cells were cultured in 96-well plates and activated with control, TNF(50 ng/mL) or P. aeruginosa (0.05 OD) media for 2 hours. Neutrophils isolated from whole blood were added to each well and incubated for 15 minutes, then imaged before and after 5x PBS washes. (A) Representative images of endothelial cells (red) and neutrophils (green) before and after washing to remove non-adherent cells. (Scale bar = 100 μm) (B, C) Neutrophil adhesion fraction was quantified by counting neutrophils adherent after washing and dividing by the neutrophil count before washing. Data represent average adhesion fraction ± SEM for 3 independent experiments per cell type. One-way ANOVA with Tukey-Kramer pairwise comparisons testing was done for each condition, with asterisks indicating statistical significance between conditions (*p<0.05).

Article Title: mRNA-based CAR T cell engineering: Unmodified mRNA enables high CAR expression without innate immune activation in T cells

doi: 10.1016/j.omtn.2025.102805

Figure Lengend Snippet: Cell-intrinsic responses toward mRNA and its nucleoside chemistries vary between cell types (A) Umbilical vein endothelial cells, (B) bone marrow stromal cells, (C) renal tubular epithelial cells, (D) macrophages and (E) T cells (all primary human cells) were transfected with unmodified (U) or m1Ψ-modified or 5 moU-modified GFP-encoding mRNA using lipofectamine complexes (or LNP for T cells). UNTR = untransfected cells. Cellular responses were measured 24 h post-transfection (from left to right): The expression level (MFI = mean fluorescence intensity) and the fraction of mRNA-expressing cells measured by quantifying GFP fluorescence using flow cytometry with equal GFP-laser settings for all measurements of all cell types. Cell viability measured using flow cytometry. Increase in activity of caspases 3 and 7, expressed as fold change from untransfected cells, was measured using a luminescence-based assay. Concentration of type-I interferons α and β in supernatants. Data presented as mean ± SD, n ≥ 3. ∗ p < 0.05; ∗∗ p < 0.01; ∗∗∗ p < 0.001; ns = not significant.
