An improved in vitro bioassay for the study of 5-HT(4) receptors in the human isolated large intestinal circular muscleN H Prins
Department of Gastrointestinal Pharmacology, Janssen Research Foundation, Beerse, Belgium
Br J Pharmacol 129:1601-8. 2000..This new bioassay allows the focused, pharmacological characterization of human colonic 5-HT(4) receptors in vitro...
Characterization of the receptors involved in the 5-HT-induced excitation of canine antral longitudinal muscleN H Prins
Department of Gastrointestinal Pharmacology, Janssen Research Foundation, Beerse, Belgium
Br J Pharmacol 134:1351-9. 2001..3 microM). 8. In conclusion, dog antral longitudinal muscle is endowed with (1) excitatory neuronal 5-HT4 receptors and 5-HT2B receptors and (2) inhibitory smooth muscle 5-HT7 receptors...
5-HT(4) receptors mediating enhancement of contractility in canine stomach; an in vitro and in vivo studyN H Prins
Department of Gastrointestinal Pharmacology, Janssen Research Foundation, Beerse Belgium
Br J Pharmacol 132:1941-7. 2001..1 microM) (124%). In conclusion, the effects of 5-HT(4) receptor agonists on proximal stomach motor activity in vivo can be explained by an effect on 5-HT(4) receptors on cholinergic nerves within the gastric muscle wall...
5-HT(4) receptors on cholinergic nerves involved in contractility of canine and human large intestine longitudinal muscleN H Prins
Department of Gastrointestinal Pharmacology, Janssen Research Foundation, Beerse, Belgium
Br J Pharmacol 131:927-32. 2000....
The in vitro pharmacological profile of prucalopride, a novel enterokinetic compoundM R Briejer
Department of Gastrointestinal Pharmacology, Janssen Research Foundation, Turnhoutseweg 30, 2340 Beerse, Belgium
Eur J Pharmacol 423:71-83. 2001....
Effects of the enterokinetic prucalopride (R093877) on colonic motility in fasted dogsM R Briejer
Department of Gastrointestinal Pharmacology, Janssen Research Foundation, Beerse, Belgium
Neurogastroenterol Motil 13:465-72. 2001..It induces GMCs and causes proximal colon stimulation and distal colon inhibition of contractile motility patterns by stimulating 5-HT4 receptors...
Pharmacological characterization of the 5-HT receptors mediating contraction and relaxation of canine isolated proximal stomach smooth muscleP Janssen
Heymans Institute of Pharmacology, Ghent University, Gent, Belgium
Br J Pharmacol 136:321-9. 2002..75+/-0.14 respectively), indicative of 5-HT(7) receptor involvement. 5. It is concluded that 5-HT induces dog proximal stomach (LM) contraction via smooth muscle 5-HT(2A) receptors and relaxation via smooth muscle 5-HT(7) receptors...
Smooth muscle 5-HT2A receptors mediating contraction of porcine isolated proximal stomach stripsP Janssen
Heymans Institute of Pharmacology, Ghent University, Ghent, Belgium
Br J Pharmacol 137:1217-24. 2002..A ketanserin-insensitive phase of contractions could not be characterized between the actually known classes of 5-HT receptors with the pharmacological tools that were used...
In vivo characterization of 5-HT1A receptor-mediated gastric relaxation in conscious dogsP Janssen
Heymans Institute of Pharmacology, Ghent University, Ghent, Belgium
Br J Pharmacol 140:913-20. 2003..It is concluded that flesinoxan induces proximal gastric relaxation in conscious dogs via 5-HT1A receptors. The response is mediated through a vagal pathway without involvement of nitrergic nerves...
5-HT4 receptors located on cholinergic nerves in human colon circular muscleP G Leclere
Heymans Institute of Pharmacology, Ghent University, Ghent, Belgium
Neurogastroenterol Motil 17:366-75. 2005..All effects of prucalopride were antagonized by the selective 5-HT4 receptor antagonist GR113808. The results obtained indicate the presence of excitatory 5-HT4 receptors on cholinergic nerves within the CM of human colon...
