Abstract

The presence and distribution of FMRFamide-like peptides (FLPs) in the cyprid larvae of the barnacle Balanus amphitrite were investigated using immunohistochemical methods. Barnacles are considered to be one of the most important constituents of animal fouling communities, and the cyprid stage is specialized for settlement and metamorphosis into the sessile adult condition. FLPs immunoreactive (IR) neuronal cell bodies were detected in both the central and the peripheral nervous system. One bilateral group of neurons somata was immunodetected in the brain, and IR nerve fibers were observed in the neuropil area and optic lobes. Intense immunostaining was also observed in the frontal filament complex: frontal filament tracts leaving the optic lobes and projecting towards the compound eyes, swollen nerve endings in the frontal filament vesicles, and thin nerve endings in the external frontal filament. Thin IR nerve fibers were also present in the cement glands. Two pairs of neuronal cell bodies were immunodetected in the posterior ganglion; some of their axons appear to project to the cirri. FLPs IR neuronal cell bodies were also localized in the wall of the dilated midgut and in the narrow hindgut; their processes surround the gut wall and allow gut neurons to synapse with one another. Our data demonstrated the presence of FLPs IR substances in the barnacle cyprid. We hypothesize that these peptides act as integrators in the central nervous system, perform neuromuscular functions for thoracic limbs, trigger intestinal movements and, at the level of the frontal filament, play a neurosecretory role.

10. Immunohistochemical FMRFamide-like distribution in the cyprid of the barnacle Balanus amphitrite

Abstract

The presence and distribution of FMRFamide-like peptides (FLPs) in the cyprid of the barnacle Balanus amphitrite were investigated by immunohistochemical methods. FLPs immunoreactive (IR) neuronal cell bodies were detected in both central and peripheral nervous system. In the brain three contralateral neuron somata were immunodetected and numerous IR nerve fibers in the neuropil area and optic lobes were observed. An intense immunostaining was also observed in the frontal filament complex: frontal filament tracts leaving the optic lobes and projecting towards the compound eyes, the swollen nerve endings in the frontal filament vesicles and the thin nerve endings in the external frontal filament. Thin IR nerve fibers were also present in the cement glands. Two pairs of neuronal cell bodies were instead immunodetected in the posterior ganglion; some of their axons seem to project to the cirri. FLPs IR neuronal cell bodies were also localized in the wall of the dilated mid-gut and in the narrow hindgut; their processes surround the gut wall and allow gut neurons to synapse each others. Our data demonstrated the presence of FLPs in the barnacle cyprid; their distribution allows us to hypothesise for these peptides an integrator role in the central nervous system, neuromuscular functions for thoracic limbs and intestinal movements and a neurosecretory role, exerted by the frontal filament complex, in the settlement and molting.

Abstract

To investigate whether the signs of neurophysiological impairment observed in flight may be traced back to cytomorphology, we undertook a ground-based study focusing upon the architecture of cultured glial cells under simulated microgravity obtained by three-dimensional clinorotation.

Abstract

The aim of the present study was to investigate the presence and distribution of cholinergic molecules in Balanus amphitrite cyprids and their possible involvement in the settlement adhesion process. Acetylcholinesterase (the lythic enzyme of acetylcholine) activity was detected, for the first time, by biochemical and histoenzymological methods, in the thoracic muscles, gut wall and cement gland. The immunodetection of ChAT-like molecules in the same area and in the neuropil of the central nervous system suggests the presence of a cholinergic innervation, and the involvement of acetylcholine in muscular contraction and cement gland exocytosis. The binding of FITC-conjugate alfa bungarotoxin in the cement gland cells confirms the latter hypothesised role. Furthermore by experimental laboratory tests, and using different logarithmic concentrations of cholinergic antagonists and agonists, the acetylcholine involvement in the barnacle settlement process was also investigated. An increase of acetylcholine available, due to the partial inhibition of AChE activity, produces an increase of percentage of the cyprid settlement. The data presented leads us to hypothesise that acetylcholine can play a neurotransmitter/neuromodulator role in barnacle cyprids and that is involved in the settlement adhesion processes.
