Abstract
The distribution of chromogranin A and neuron specific enolase (NSE) in the neuroendocrine gut system and the morphology and distribution of cells containing gastrin, somatostatin, neurotensin and VIP in the gastroenteropacreatic (GEP) apparatus of Erinaceus europaeus were investigated by immunohistochemical methods. Chromogranin A and somatostatin immunoreactive cells were present throughout the gastrointestinal mucosa, with the exception of the oesophagus and in the pancreas. Gastrin cells were peculiar of the pyloric glands and duodenal mucosa and neurotensin cells of the small intestine. No VIP immunoreactive endocrine cells were noticed in the GEP system. VIP and NSE immunoreactivities were detected both in nerve cell bodies and terminals of the wall of the GEP apparatus. NSE immunoreactivity was found in the endocrine cells of the fundic and pyloric mucosa.
