Multiple CF innervation by ascending CF branches after induction of GluRδ2 ablation. Each panel shows parasagittal cerebellar sections subjected to dextran Alexa-594 tracer labeling for CFs (DA-594; red) and immunofluorescence for calbindin (calb; blue) and VGluT2 (green) in GluRδ2flox/flox at 2 weeks after RU-486 administration (A) and GluRδ2flox/CrePR mice at 2 weeks (B), 8 weeks (C), and 24 weeks (D) after RU-486 administration. Immunoreaction for calbindin is pseudocolored in blue (A1–D1) or brown (A2–D2, A3–D3). CF-a indicates the CF mainly innervating a PC dendrite of interest (PCD-a). In GluRδ2flox/CrePR mice at 8 and 24 weeks, PCD-a is multiply innervated by both main CF-a and additional CF-b (arrows). Scale bars, 10 μm.
