The expression of glial cell line-derived neurotrophic factor receptor α2 (GFR-α2) in neurones that project to the penis is modulated by sildenafil (SIL) after bilateral cavernosal nerve resection (BCNR). Frozen pelvic ganglia sections (as in Fig. 1) were immunostained with a polyclonal antibody against GFR-α2 followed by a biotinylated secondary antibody and streptavidin conjugated with Texas red. Red: GFR-α2; yellow: Fluorogold (FG). Magnification × 100. Scale bar = 100 μm. SHAM, sham-operated.
