Biodistribution of radiolabeled targeted-NPs (anti-ICAM-1/NPs or IgG/NPs as a control) 30 min after intravenous injection in control or TNFα-injured animals. (A) Blood, (B) lungs, (C) brain. *** (p<0.001, IgG vs anti-ICAM-1), *(p<0.05, IgG vs anti-ICAM-1), ### (p<0.001 anti-ICAM-1: Control vs TNFα). One-way ANOVA (Bonferroni post-hoc analysis). Mean±SD, controls n=6, TNFα n=3.
