Histochemistry and function of bombesin-like peptides.
1986
: Bombesin-like peptides are a group of brain-gut peptides found in several neuronal groups in the central nervous system and in peripheral intrinsic gut neurons and sensory neurons. The SIF cells (small intensely fluorescent cells) of the sympathetic ganglia also contain immunoreactivity for these peptides. These peptides are present in some pulmonary endocrine cells and tumors originating from these cells. Chromatographic studies suggest that several different peptides, possibly originating from at least two different precursors, are present in mammalian tissues. Authentic amphibian peptide bombesin does not appear to be found in mammalian tissues. Functional studies indicate that these peptides may be involved in many important functions, including sensory transmission, regulation of central autonomic pathways, thermoregulation, secretion of pituitary hormones, gastric and pancreatic secretion, food intake and satiety.
