  • Research interest:1. During my medical training, I participated in several experiments focusing on the characterization of neurotransmitters in motility of the mouse small intestine. We found evidence for a role of ATP in inhibitory neurotransmission and of all three tachykinin receptor subtypes in excitatory neurotransmission. a. De Schepper HU, De Winter BY, Seerden TC, Herman AG, Pelckmans PA, De Man JG. The role of tachykinins in circular muscle contractility of the murine ileum: a functional investigation. Auton Neurosci. 2006 ;126-127: 273-6. b. De Schepper HU, De Winter BY, Seerden TC, Herman AG, Pelckmans PA, De Man JG. Functional characterisation of tachykinin receptors in the circular muscle layer of the mouse ileum. Regul Pept. 2005; 130: 105-15.2. During my PhD I performed both functional and electrophysiological experiments detailing the effects of acute TNBS colitis in rats on gastrointestinal motility and sensitivity. The main contribution of this work was to identify TRPV1 receptors as potential therapeutic targets in visceral pain. a.

Role of TRPV1 and TRPA1 in visceral hypersensitivity to colorectal distension during experimental colitis in rats. Eur J Pharmacol. 2013; 698: 404-12.b.

Acute distal colitis impairs gastric emptying in rats via an extrinsic neuronal reflex pathway involving the pelvic nerve. Gut. 2007; 56: 195-202.3. During my fellowship at the motility department of the AMC Amsterdam, I performed 2 technical studies on the performance of high resolution esophageal manometry in detecting esophageal motility disorders. a.

Neurogastroenterol Motil. 2014; 26: 922-8.4. As a senior resident in the University Hospital of Antwerp, I have established a gastrointestinal motility clinic with a florid multidisciplinary pelvic floor unit. Several clinical research projects are currently ongoing, of which the first has now been published, concentrating on the manometric characterization of patients with fecal incontinence. a.
