Butyrylcholinesterase distribution in the mouse gastrointestinal tract: An immunohistochemical study.

ABSTRACT: Butyrylcholinesterase (BChE) is a hydrolytic enzyme that together with acetylcholinesterase (AChE) belongs to the cholinesterase family. Whereas AChE has a well-established role in regulating cholinergic neurotransmission in central and peripheral synapses, the physiological role of BChE remains elusive. In this morphological immunohistochemical and double-label confocal microscopy study we investigated the distribution of BChE in the mouse gastrointestinal tract. BChE-positive cells were detected in the liver (both in hepatocytes and cholangiocytes), in the keratinised layers of the squamous epithelium of the oesophagus and forestomach, in the oxyntic mucosa of the stomach, in the mucus-secreting cells of duodenal Brunner glands and the small and large intestinal mucosa. Interestingly, BC
