Distribution of dopaminergic nerve fibers on the salivary gland acini Whole mounts of salivary glands were double-labeled with anti-dopamine (red) and BODIPY FL phallacidin (blue), and imaged by confocal microscopy. Parameters of image acquisition and data presentation are identical to those of Fig. 4. Dopaminergic fibers and their endings (arrowheads) reside on the acinar surface over and between the peripheral cells (asterisks). The inner part of the acinar lobule with the central cells and the acinar lumen (arrows in f) lacks dopaminergic fibers. Scale bar = 50 μm
