Figure 6. Colocalization of Cx43 and CD45 was seen only in the light-damaged choroid. A–C: Cx43 labeling (A), CD45 labeling (B), and combined images (C) in the non-light-damaged choroid. CD45 immunolabeled macrophages did not show Cx43 coexpression. D–F: Cx43 labeling (D), CD45 labeling (E), and combined images (F) at 24 h post-LD. Many CD45 immunolabeled macrophages (arrows in F) showed Cx43 immunoreactivity in the choroid at this time point. Abbreviations: LD, light damage. Scale bar = 50 µm.
