Figure 6From: Comparative iron oxide nanoparticle cellular dosimetry and response in mice by the inhalation and liquid cell culture exposure routesMicroarray data and PCR validation of transient induction of transcripts (compared to time matched controls) for key inflammatory cytokines. Induction of cytokines was prominent at 4 hours, but resolved by the peak of macrophage infiltration at 48 hours.Back to article page
