SiO2 NPs cause the secretion of IL-1β and TNF-α. Retinal sections were prepared as described in Fig. 7. At 1 d (A and C) and 7 d (B and D) after SiO2 NP injection, retinas were stained with the antibodies of TNF-α and IL-1β. Representative images showing the distributions of IL-1β (red) and TNF-α (green). The bar graph depicts the mean fluorescence intensity. *p < 0.05 compared to the sham group. Scale bar: 100 μm
