Figure Lengend Snippet: Luminescence intensities of (A) Jurkat, (B) NK-92 mi, and (C) RAW 264.7 cells transfected with FLuc linear or circular RNA-loaded PAsp­(DET/CHE) polyplexes ( N / P = 2.8, 100 ng RNA/well) for 24 h. Results are expressed as mean ± SD ( n = 4). (D) Cellular uptake of naked Cy5-RNA and Cy5-RNA-loaded PAsp­(DET/CHE) polyplexes ( N / P = 2.8, 500 ng Cy5-RNA/well) into Jurkat, NK-92 mi, and RAW 264.7 cells after incubation for 4 h, measured using flow cytometry.

doi: 10.1101/2025.10.30.685267

Figure Lengend Snippet: Efferocytosis of apoptotic Jurkat cells labeled with CellTrace™ Violet by CD66b-positive granulocytes stained with CellTrace™ Far Red was examined under various conditions. (A) PMNs were exposed to varying concentrations of β2m or dK58β2m in the presence of apoptotic Jurkat cells. (B) PMNs were treated with apoptotic cells alone or in combination with 50 µg/ml β2m, 50 µg/ml dK58β2m, 100 ng/ml GM-CSF, or combinations thereof. (C-D) PMNs were treated with apoptotic Jurkat cells with 50 µg/ml β2m (C) or dK58β2m (D) combined with 10 or 25% human AB serum. In all experiments, a 4:1 apoptotic cell-to-PMN ratio was used. Treatment with 100 ng/ml GM-CSF served as a positive control, and pre-incubation with 10 µg/ml cytochalasin D (cyto D) served as a negative control. Results are shown as mean ± SD of double-positive PMNs. Sample sizes were n=6 or n=4 (A), n=10 (B), and n=8 or 3 donors (C and D). Group comparisons were analyzed using mixed-effects analysis and Tukey’s multiple comparisons test (A, C, and D) or repeated-measures ANOVA and Tukey’s multiplecomparisons test(B). Statistical significance is indicated by *P < 0.05 and **P < 0.01, ***P < 0.001, ****P < 0.0001.
