Fragile X mental retardation protein is required for programmed cell death and clearance of developmentally-transient peptidergic neurons. Develop.
Anatomical characterization of PDF-tri neurons and peptidergic neurons associated with eclosion behavior in Drosophila.
(S1-positive) form at the base of the anterolateral arms during larval arm resorption and may be involved in metamorphosis (Cisternas and Byrne, 2003).
Innervation of gonadotropin-releasing hormone neurons by peptidergic neurons
conveying circadian or energy balance information in the mouse.
The innervation of the DB in Helix aspersa and Theba pisana originates from peptidergic neurons
of the cerebral ganglia (cerebral green cells, CGC) via commissural nerves.
The role of pacemaker properties and synaptic input in generation and modulation of spiking activity in a pair of electrically coupled peptidergic neurons

in the snail Helix pomatia: distribution of neurons in the central and peripheral nervous system that react with an antibody raised to an insect myotropic neuropeptide, leucokinin I.
This consists of a network or basket of peptidergic neurons that surrounds the base of clustered cnidocytes, together with a finite number of peptidergic sensory neurons that send processes to the surface of the tentacle.
EM studies of cnidocytes in the anemone Aiptasia (Westfall, 2004), on the other hand, have revealed the presence of RFamide immunoreactive densecored vesicles at neuro-cnidocyte synapses, suggesting that cnidocytes in anemones are indeed innervated by peptidergic neurons. The lack of a clear association between the immunoreactive nerve nets and cnidocytes may, therefore, simply be a consequence of the anemone's anatomy.
Finally, PCD of peptidergic neurons has been observed in the fly and the moth (Ewer et al., 1998; Draizen et al., 1999).
Genetic and hormonal regulation of the death of peptidergic neurons in the Drosophila central nervous system.
Because the morphology of the barnacle nervous system is so unusual, and because peptidergic neurons
in those systems are so little known, the methods of immunohistochemistry were used to define and map neurons that might be producing peptides homologous to those now identified in some decapod crustaceans.
