2013, Poultry ScienceCitation Excerpt :Neurotensin (NT) is a tridecapeptide that is distributed widely in the central nervous system and peripheral tissues of vertebrates and has multiple functions as a neurotransmitter and as a circulating hormone (Reinecke, 1985; St-Gelais et al., 2006; Kalafatakis and Triantafyllou, 2011). In the chicken, NT was initially isolated from the intestine (Carraway and Bhatnagar, 1980). Thereafter, NT immunoreactivity was found in the epithelium and nerve fibers of the smooth muscle layers of the gastrointestinal tract (Atoji et al., 1994, 1995), endocrine cells of the thymus (Atoji et al., 1996), and the hypothalamus in the brain (Esposito et al., 1997).
Neurotensin and cholecystokinin contract gallbladder circular muscle in chickens
2013, Poultry ScienceCitation Excerpt :Contractions were recorded via force transducers that were connected to a 4-channel polygraph (model 79-D, Grass Instruments, Quincy, MA). Avian NT has been isolated from the intestine of chickens and has a sequence similar to bovine NT (Carraway and Leeman, 1973) except for the substitution of His3, Val4, and Ala7 for Tyr3, Glu4, and Pro7(Carraway and Bhatnagar, 1980). The biologically active carboxy-terminus of the peptide is common to both species.
