Endocrine-like cells and insulin-binding sites in the epineurium of Helix pomatia.
Endocrine/paracrine-like cells are described for the first time in the epineurium of the cerebro-subesophageal ganglia connectives and in the epineurium of the nervus pallialis dexter et internus of Helix pomatia. At least a population of these cells contains insulin-immunoreactive material. Immunoelectron-microscopic investigations showed that electron-dense granules exhibit insulin-like material. Insulin-binding studies revealed granular cells as putative target-cells of insulin in the epineurium.
