Autor: Yangxi Wang, A. Couvineau, T. Voisin, C Rouyer-Fessard, Dallas M. Swallow, D. Darmoul, M. Laburthe, R. Salomon
Publikováno v: Biochemical and Biophysical Research Communications. 203:1224-1229
The expression of DPP IV/CD26 was studied in epithelial cells from different regions of the human small intestine and colon. The following data were obtained: 1) DPP IV/CD26 activity was highest in ileum and jejunum, low in duodenum and not detectabl

The human VPAC1 receptor: three-dimensional model and mutagenesis of the N-terminal domain
Autor: L, Lins, A, Couvineau, C, Rouyer-Fessard, P, Nicole, J J, Maoret, M, Benhamed, R, Brasseur, A, Thomas, M, Laburthe
Publikováno v: The Journal of biological chemistry. 276(13)
The human VPAC(1) receptor for vasoactive intestinal peptide (VIP) and pituitary adenylate cyclase activating peptide belongs to the class II family of G-protein-coupled receptors with seven transmembrane segments. Like for all class II receptors, th

alpha(2)-adrenergic receptors stimulate oligopeptide transport in a human intestinal cell line
Autor: F, Berlioz, J J, Maoret, H, Paris, M, Laburthe, R, Farinotti, C, Rozé
Publikováno v: The Journal of pharmacology and experimental therapeutics. 294(2)
Di- and tripeptides, as well as peptidomimetic drugs such as cephalexin (CFX), are absorbed by enterocytes via the oligopeptide transporter PepT1. We recently showed that the alpha(2)-adrenergic agonist clonidine increases CFX absorption in anaesthet

Identification of key residues for interaction of vasoactive intestinal peptide with human VPAC1 and VPAC2 receptors and development of a highly selective VPAC1 receptor agonist. Alanine scanning and molecular modeling of the peptide
Autor: P, Nicole, L, Lins, C, Rouyer-Fessard, C, Drouot, P, Fulcrand, A, Thomas, A, Couvineau, J, Martinez, R, Brasseur, M, Laburthe
Publikováno v: The Journal of biological chemistry. 275(31)
The widespread neuropeptide vasoactive intestinal peptide (VIP) has two receptors VPAC(1) and VPAC(2). Solid-phase syntheses of VIP analogs in which each amino acid has been changed to alanine (Ala scan) or glycine was achieved and each analog was te

Functional and molecular properties of the human recombinant Y4 receptor: resistance to agonist-promoted desensitization
Autor: T, Voisin, M, Goumain, A M, Lorinet, J J, Maoret, M, Laburthe
Publikováno v: The Journal of pharmacology and experimental therapeutics. 292(2)
After stable transfection of Chinese hamster ovary cells with the human Y4 receptor, clone 29 was isolated and studied for receptor properties. The following data were obtained: 1) one class of binding site was identified by analysis of (125)I-human

Vasoactive intestinal peptide (VIP)1 receptor. Three nonadjacent amino acids are responsible for species selectivity with respect to recognition of peptide histidine isoleucineamide
Autor: A, Couvineau, C, Rouyer-Fessard, J J, Maoret, P, Gaudin, P, Nicole, M, Laburthe
Publikováno v: The Journal of biological chemistry. 271(22)
Vasoactive intestinal peptide (VIP)1 receptors in rats and humans recognize peptide histidine isoleucineamide (PHI) with high and low affinity, respectively. We took advantage of this phenotypic difference to identify the domain responsible for the s

Receptors for gut regulatory peptides
Autor: M, Laburthe, A, Couvineau, B, Amiranoff, T, Voisin
Publikováno v: Bailliere's clinical endocrinology and metabolism. 8(1)
Receptors for regulatory peptides (hormones or neurotransmitters) play a pivotal role in the ability of cells to taste the rich neuroendocrine environment of the gut. Recognition of low concentration of peptides with a high specificity and translatio

Structure-activity studies of peptide YY(22-36): N-alpha-Ac-[Phe27]PYY(22-36), a potent antisecretory peptide in rat jejunum
Autor: A, Balasubramaniam, H M, Cox, T, Voisin, M, Laburthe, M, Stein, J E, Fischer
Publikováno v: Peptides. 14(5)
Peptide YY (PYY) and its homologous peptide, neuropeptide Y (NPY), are known to exhibit potent antisecretory effects in the intestine. To determine the structural requirements to elicit antisecretory effects, we have synthesized several analogs of th
