Postembryonic alteration of transmitter phenotype in individually identified peptidergic neurons.
Many neurons are now known to undergo dramatic morphological or biochemical changes long after they have completed differentiation and maturation. The ability of fully mature neurons to alter their transmitter phenotype has been amply demonstrated in culture, but direct in vivo data on single neurons have been difficult to obtain. Here we show that a set of 4 individually identified neurosecret...
متن کاملSteroid-regulated Morphological Plasticity in a Set of Identified Peptidergic Neurons in the Moth Manduca Sexta
The lateral neurosecretory cells (LNCs) in the tobacco hornworm Manduca sexta undergo a switch in neurotransmitter phenotype during pupation. Concurrent with this change in function, the LNCs undergo a major morphological reorganization. This study characterizes the morphological change and its underlying cause. In the larva, the LNC has a very compact dendritic arborization in a small volume o...
متن کاملPeptidergic modulation of patterned motor activity in identified neurons of Helisoma.
The neuroactive peptides SCP(B) (small cardioactive peptide B) and FMRFamide (Phe-Met-Arg-Phe-NH(2)), both originally isolated from molluscs, have potent modulatory effects upon the production of patterned motor activity in identified neurons (e.g., B5 and B19) in the buccal ganglia of the snail Helisoma. Such patterned motor activity has previously been shown to underlie feeding behavior. Micr...
متن کاملSerotonin activates a Ca(2+)-dependent K(+) current in identified peptidergic neurons from the crayfish.
The effects of 5-hydroxytryptamine (5-HT) were investigated in red pigment concentrating hormone (RPCH)-containing neurons isolated from the X-organ of the crayfish (Procambarus clarkii). Under current-clamp conditions and using the gramicidin-perforated-patch configuration, 5-HT elicited a prolonged hyperpolarization that suppressed neuronal firing concomitant with an increase in membrane cond...
متن کاملPeptidergic input to immunohistochemically-identified Renshaw cells.
Peptidergic influences on Renshaw cells were assessed in rat using gephyrin-immunoreactivity, as a Renshaw cell specific marker, in combination with substance P, calcitonin gene-related peptide- and nicotinic acetylcholine receptor-immunolabelling. An average of 3.9 substance P-, and 8.1 calcitonin gene-related peptide-, and 16.3 nicotinic acetylcholine receptor-immunoreactive close contacts or...
