FIGURE 9. IL-33 and IL-12 regulate TNF release via ADAM17.
Enriched human NK cells were pretreated with 0.1% DMSO, R-1503 (0.25 μM) or TAPI-1 (8 μM) and then stimulated in the presence of cytokines (doses listed in ng/mL) for 16 h. (A) Secreted TNF expression was measured by ELISA where each dot represents the mean of 3 biological replicates of an independent subject (n = 6). (B) Cell-associated TNF was measured by flow cytometry where each dot represents the mean of 2 biological replicates of an independent subject (n = 4). Shaded bars reflect administration of >1 cytokine. Multiple comparisons of ordinary 1-way ANOVA were used to compare columns with P < 0.1 shown
