title: Neuropeptide F-immunoreactivity in the tetrathyridium of Mesocestoides corti (Cestoda: Cyclophyllidea).
abstract: The distribution pattern and subcellular localisation of neuropeptide F (NPF) immunoreactivity (IR) in the tetrathyridium stage of Mesocestoides corti were investigated by whole-mount immunocytochemistry in conjunction with confocal scanning laser microscopy (CSLM) and by immunoelectron microscopy using immunogold labeling. Using an antiserum directed to the C-terminal decapeptide amide (residues 30-39) of synthetic NPF (Moniezia expansa), CSLM revealed NPF-IR throughout the central and peripheral nervous systems of parental and dividing tetrathyridia. Ultrastructurally, gold labeling of NPF-IR was confined to the contents of the smaller of the two sizes of electron-dense neuronal vesicle identified.
