Induction of NLRP3 Inflammasome Activation by Heme in Human Endothelial Cells

Figure 4

The coordinated iron is critical in heme-mediated induction of IL-1β. (a and b) HUVECs primed with LPS (10 μg/mL, 24 h) were stimulated with heme, PPIX, or FeSO4 (25 μmol/L). (a) IL-1β mRNA level (4 h) was determined by quantitative RT-PCR. (b) Active IL-1β levels in cellular supernatants (24 h) were determined by ELISA. Results are shown as mean ± SD () from one representative experiment of three. .
