Figure Lengend Snippet: A Schematic overview of the induction and inhibition of different regulated cell death pathways in vitro. B Cell death in CD14+ monocytes from healthy controls (HC) and DADA2 patients was measured by flow cytometric measurement of staining with Annexin V and Zombie® viability dye. Cells were incubated for 5 h. Apoptosis (TS) and necroptosis (TSZ) were induced by stimulation with 100 nM birinapant (SM) ± 20 µM Z-VAD-FMK (Z-VAD) followed by 20 ng/mL tumour necrosis factor-alpha (TNF-α). Inhibition of necroptosis was achieved by adding 10 µM necrostatin-1s (Nec-1s, TSZN). Plots show median and 25 and 75th percentiles. Data from n = 19 (HC) and n = 14 (DADA2, comprising n = 7 distinct patients) independent experiments are shown. Mann-Whitney-U test, ** p < 0.01. The patients’ phenotype is indicated by colour as displayed in Fig. .
