Fig. 2From: Impact of pulmonary exposure to gold core silver nanoparticles of different size and capping agents on cardiovascular injurySerum Cytokine Concentrations Following IT instillation of PVP Capped AgNP. Graphs presenting mean serum concentration of selected cytokines 1 day (panels a, c, e and g) and 7 days (panels b, d, f and h) after IT instillation. Cytokines IL-2 (a) IL-6 (c) IL-18 (d) and G-CSF (e) were modestly elevated compared to citrate vehicle 1 day following IT instillation. At 7 days following instillation cytokine concentration was not elevated above vehicle. (b) denotes statistical significance from vehicle, (c) denotes significance from other AgNP particle size within a capping agent. p < 0.05 by one-way ANOVA, Data are reported as mean ± SEM with n = 4–8Back to article page
