An immunohistochemical study of gut endocrine cells in two species of insectivorous vespertilinid bats (Chiroptera: Pipistrellus abramus and Plecotus auritus sacrimontis).
11 endocrine cell types immunoreactive for either 5-hydroxytryptamine (5-HT), somatostatin, gastrin, cholecystokinin (CCK), gastric inhibitory peptide (GIP), motilin, secretin, neurotensin, pancreatic glucagon, enteroglucagon or bovine pancreatic polypeptide (BPP) were found in gastrointestinal tract of 2 species of insectivorous bats. 5 of these 11 types of endocrine cells were located in the stomach and all 11 types of endocrine cells were found in the intestine. However, the distribution and relative frequency of each immunoreactive endocrine cell varied among the cell types and between the 2 species of bats examined. In Brunner's glands, gastrin- and 5-HT-immunoreactive cells were detected very rarely in Pipistrellus and only occasionally in Plecotus. The present results obtained from the insectivorous bats were compared with those of the sanguivorous vampire bats.
