Deletion of IL-33 results in increased immune cell infiltration following detachment. a–f Representative images of WT and IL-33^−/− retinal sections stained for CD68 (red) and DAPI (blue) in a WT day 4, b WT day 7, c WT day 28, d IL-33^−/− day 4, e IL-33^−/− day 7 and f IL-33^−/− day 28 post-RD. g The number of CD68⁺ cells in the subretinal spaces of WT and IL-33^−/− eyes at day 4, day 7 and day 28 post-RD. Data were presented as mean ± SEM. n = 5 mice, 3–6 sections per retina, Student’s t test were used to compare the cell number between two groups at the same time point. ***P < 0.001. Scale bar, 100 μm
