Figure 6. Double immunostaining against CD11b (green) and PKC-α (red). A: One hour after light exposure, tight interaction between microglial processes and dendrites of bipolar cells is observed (arrow). B: At day 3, some activated microglia are observed in the subretinal space (arrowhead), and tight interaction between microglia and bipolar cells can still be observed. Scale bar: 50 μm.
