Effect of polymyxin B on the induction of pro–IL-1β mRNA level.
Nonadherent human monocytes (8 × 106 cells) were untreated or stimulated for 1 hour at 37°C with either anti-CD11b (5 μg/mL), anti-CD11c (5 μg/mL), LPS (200 ng/mL), ZZ-CD23 (1 μg/mL), or MBP-CD23 (1 μg/mL), in the presence or absence of polymyxin B (10 μg/mL).
