Fig. 2. The AP-2 adaptor complex is necessary for norpA-mediated retinal degeneration. All panels show cross sections (0.5 µm) of retinas from (A) wild-type, (B) norpA, (C)
-adaptin and (D) norpA;
-adaptin flies. The flies were dark-reared and then exposed to 5 days of constant room light prior to fixation. Tissue was fixed and embedded as described in Materials and Methods.
