Figure 1. Targeting of anti-ICAM-1 monoclonal antibody to the inflamed brain.
Biodistribution of radiolabeled IgG or anti-ICAM-1 in control or TNFα-injured animals one hour after IV injection. (A) blood, (B) lungs, (C) brain. %ID/g: percent of injected dose per gram of tissue, ISI: immunospecificity Index (ratio (blood normalized anti-ICAM-1/liposomes in brain)/(blood normalized IgG/liposomes in brain)). *** (p<0.001, 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 IgG n=8, and TNF anti-ICAM-1 n=7.
