PMNL (5 × 10⁶) were preincubated with control (0.1% DMSO), BRP-187, Acdex, PLGA, Acdex[BRP-187] and PLGA[BRP-187] NPs for the indicated time points at 37 °C. The cells were then stimulated with 2.5 µM A23187 for 10 min, and 5-LO product formation was analyzed. Values are given as ng of 5-LO products (sum of the trans-isomers of leukotriene B₄ (LTB₄), LTB₄ and 5-hydroxyeicosatetraenoic acid (5-HETE)). For statistical analysis, one-way ANOVA and Tukey’s multi comparison test was performed. p < 0.05 (*); p < 0.01 (**); p < 0.001 (***); n = 4
