“…The regional distribution and relative frequency of the immunoreactive cells in M. molossus and L. aurita is similar to that of other species of chiropterans (Yamada et al, 1988;Ashihara et al, 1999;Komori et al, 2000;Santos et al, 2008). However, in this study some characteristics observed mainly in the cells immunoreactive to CCK and to enteroglucagon differed from the other species of chiropterans previously studied.…”

“…Fifteen types of endocrine cells have been demonstrated in the gastrintestinal tract of bats by immunohistochemistry. Nine types of endocrine cells have been shown in the vampire bat Desmodus rotundus (Yamada et al,1984), eleven in the insectivorous bats Pipistrellus abramusi and Plecotus auritus (Yamada et al, 1988), eight in nectarivorous and frugi-nectarivorous bats Anoura caudifer and r Carollia perspicillata (Ashihara et al, 1999) four in the frugivorous bats Artibeus cinerius and Sturnira lilium (Santos et al, 2008) and ten in the piscivorous Noctilio leporinus (Komori et al, 2000). These studies reveal interspecific differences and suggest correlation between endocrine cell distribution and feeding habits.…”

The regional distribution and relative frequency of endocrine cells in the stomach and intestine of Phyllostomidae: Lonchorhina aurita and Molossidae: Molossus molossus bats were studied immunohistochemically. Three types of immunoreactive (IR) endocrine cells -to serotonin (5-HT), gastrin (GAS) and enteroglucagon (GLUC) -were found in the gastric mucosa and four types of IR cells were identified in the intestinal mucosa. This study showed an interespecfic difference in the regional distribution and relative frequency of endocrine cells in the Chiropteran alimentary tract.Keywords: endocrine cells, stomach, intestine, insectivorous bats. Estudo imunocitoquímico das células endócrinas gastrintestinais de morcegos insetívoros (Mammalia: Chiroptera) ResumoA distribuição regional e a freqüência relativa das células endócrinas no estômago e intestino dos morcegos insetívoros Phyllostomidae: Lonchorhina aurita e Mormoopidae: Molossus molossus foram estudadas pelo método de imunohistoquímica. Três tipos de células endócrinas imunorreativas (IR) à serotonina (5-HT), gastrina (GAS) e enteroglucagon (GLUC) foram localizadas na mucosa gástrica e quatro tipos de células endócrinas IR à 5-HT, GAS, colecistoquinina (CCK) e GLUC foram identificadas na mucosa intestinal. Este estudo mostrou uma diferença interespecífica na distribuição regional e na freqüência relativa das células endócrinas no trato alimentar de Chiropteros.Palavras-chave: células endócrinas, estômago, intestino, morcegos insetívoros.

“…Bat intestine sections were used as positive controls, because they presented positive responses to these reactions in previous studies (e.g., Santos et al 2008aSantos et al , 2008bMachado-Santos et al 2009). The negative control was prepared by replacing the primary antibody with non-immune serum and PBS (pH 7.4).…”

The present study investigates the aspects of endocrine cells secreting cholecystokinin, gastrin, insulin, glucagon, somatostatin and serotonin in the enteropancreatic system of Tropidurus torquatus. The specimens were collected in Marambaia Island, Sepetiba Bay, Rio de Janeiro State, Brazil. The animals' intestine and pancreas were removed, fixed, processed and then subjected to immunohistochemical techniques. Three cell types, immunoreactive (IR) to gastrin, cholecystokinin-8 and serotonin, were identified in the intestinal mucosa. Serotonin was found in the small and large intestines, whereas gastrin and cholecystokinin-8 cells were only observed in the large intestine of T. torquatus. Glucagon, somatostatin and insulin were not observed in the intestines at all. Only glucagon, somatostatin and insulin were identified in the pancreas of the studied lizards. The dorsal lobe showed a large number of endocrine cells scattered throughout the exocrine parenchyma and in the exocrine duct walls. The present study shows that the intestine and pancreas of T. torquatus hold most of the regulatory peptides, presenting a structure similar to that in other vertebrates such as birds and mammals. The endocrine cells identified in the lizards' enteropancreatic system evidences the good phylogenetic preservation of the regulatory peptides' molecular structure.
