Caspase 1, IL-18, and NFκB signaling at day 1 and day 7 following exposure to pre- and post-incinerated organomodified nanoclay. Western blot and quantitative densitometry analysis of protein bands at (a) and (b) day 1 and (c) and (d) day 7 postexposure. Phosphorylated and basal protein expression was normalized to basal and B-actin protein expression, respectively. * and † indicate significant increase or decrease, respectively, compared to saline-exposed animals (n = 4, p ≤ 0.05).
