Dietary proteins are mostly absorbed as di-and tripeptides by the intestinal proton-
dependent transporter PepT1. We have examined the effects of leptin on PepT1 function in …

Some of the actions of leptin depend on cholecystokinin (CCK). However, it is unknown
whether leptin modulates the release of CCK. Here, we demonstrate in vitro that leptin …

Background and aims: Leptin, the product of the ob gene, has been suggested to increase
the risk of colon cancer. However, we have shown that although leptin stimulates epithelial …

Leptin has been suggested to be involved in tissue injury and/or mucosal defence
mechanisms. Here, we studied the effects of leptin on colonic mucus secretion and rat mucin …

In the present study, the effect of H+/peptide transporter (PepT1)-mediated N-
formylmethionyl-leucyl-phenylalanine (fMLP) transport on inflammation in vivo in the rat …

Background & Aims: Recent studies suggest that leptin, a hormone involved in food intake
regulation, released into the circulation and gastrointestinal juice, may be a growth factor for …

A peptide YY (PYY)-preferring receptor [PYY> neuropeptide Y (NPY)] was previously
characterized in rat small intestinal crypt cells, where it mediates inhibition of fluid secretion …

Intestinal absorption of β-lactamine antibiotics (eg, cefixime and cephalexin) has been
shown to proceed through the dipeptide carrier system. In a previous study, nifedipine …

Souli, A., J. Chariot, T. Voisin, O. Presset, A. Tsocas, A. Balasubramaniam, M. Laburthe and
C. RozÉ. Several receptors mediate the antisecretory effect of peptide YY, neuropeptide Y …

Mechanisms of neural (vagal and cholinergic) and hormonal [cholecystokinin (CCK)] control
of pancreatic exocrine secretion were studied in basal interdigestive conditions and after …
