- Аннотация: In the central nervous system of the terrestrial snail Helix, the gene HCS2, which encodes several neuropeptides of the CNP (command neuron peptide) family, is mostly expressed in cells related to withdrawal behavior. In the present work, we demonstrate that a small percentage (0.1%) of the sensory cells, located in the sensory pad and in the surrounding epithelial region ("collar") of the anterior and posterior tentacles, is immunoreactive to antisera raised against the neuropeptides CNP2 and CNP4, encoded by the HCS2 gene. No CNP-like-immunoreactive neurons have been detected among the tentacular ganglionic interneurons. The CNP-like-immunoreactive fiber bundles enter the cerebral ganglia within the nerves of the tentacles (tentacular nerve and medial lip nerve) and innervate the metacerebral lobe, viz., the integrative brain region well-known as the target area for many cerebral ganglia nerves. The procerebral lobe, which is involved in the processing of olfactory information, is not CNP-immunoreactive. Our data suggest that the sensory cells, which contain the CNP neuropeptides, belong to a class of sensory neurons with a specific function, presumably involved in the withdrawal behavior of the snail.
