Pinocytosis in eyes of a snail, Helix aspersa
Journal of Ultrastructure Research, 1982Extirpated eyes of the snail Helix aspersa , from which lenses were removed surgically, were incubated in horseradish peroxidase (HRP) and prepared cytochemically for electron microscopy to determine the positions of HRP. There was some internalization of tracer by pinocytic vesicles and tubules in Type I sensory cells and much uptake by Type II ...

Tyrosine hydroxylase in snail (Helix pomatia) nervous tissue
Biochemical Pharmacology, 1976Abstract Snail nervous tissue synthesizes [14]dopamine and [14]dihydroxyphenylalanine (DOPA) from [14C]tyrosine. The Km value for the overall conversion of [14C]dopamine was 6 × 10−4M. The enzyme converting [14C]tyrosine to [14C]DOPA. tyrosine hydroxylase, has the following characteristics.

CO2 chemoreception in the pulmonate snail, Helix aspersa
Respiration Physiology, 1993We have studied the response of the pneumostome to CO2, O2 and combined CO2 and O2 in intact snails. We found that pneumostomal opening increases in response to both hypercapnia and mild hypoxia. We determined which neural structures were essential for the pneumostomal response to CO2 by eliminating parts of the nervous system: the subesophageal ...

Gut endocrine cells in the snail Helix aspersa
General and Comparative Endocrinology, 1988A microscopic study of the endocrine cells present in the gut of the snail Helix aspersa is made. Electron microscopy is necessary in most cases to identify the enteroendocrine cells, since neither silver impregnations nor immunocytochemical staining have rendered positive results. Endocrine cells are scarce and rest on the basement membrane.

Calcium mobilisation during reproduction in snail Helix aspersa
Nature, 1977THE land snail Helix aspersa lays up to 100 eggs at a time, each with 0.6 mg of calcium in the form of calcite crystals. There is insufficient calcium in any part of the reproductive tract to account for this.

Structure of hemocyanin from garden snail Helix lucorum
Comparative Biochemistry and Physiology Part B: Biochemistry and Molecular Biology, 2010Hemocyanins are giant extracellular oxygen carriers in the hemolymph of many molluscs and arthropods with different quaternary structure. They are represented in the hemolymph of molluscs with one, two or three isoforms, as decameric, didecameric, multidecameric and tubules aggregates. We describe here the structure of the hemocyanin Helix lucorum (HlH)

Tissue buffering in the snail, Helix aspersa
Comparative Biochemistry and Physiology, 19701. 1. Changes in the concentrations of calcium and bicarbonate in the blood of hydrated Helix aspera, exposed to raised tensions of carbon dioxide or injected with HCl, NaHCO3 or CaCl2, were qualitatively those to be expected if the blood were in equilibrium with solid calcium carbonate. 2. 2.
