P059 Le lipido-récepteur intestinal CD36 et sa cascade de signalisation ERK1/2 dépendante contrôle la synthèse des chylomicrons

2013

International audience; Introduction et but de l’étude. – L’intestin est capable d’adapter sa capacité d’absorption à la teneur en lipide du régime. Cette adaptation implique un système de détection des lipides au niveau entérocytaire. Le CD36, qui est une glycoprotéine transmembranaire liant avec une forte affinité les acides gras à longue chaîne (AGLC), pourrait jouer ce rôle. En effet, ex vivo, la présence d’AGLC est associée à une activation de la voie ERK1/2 et conduit à l’induction de protéines clés du métabolisme intestinal des lipides : l’ApoB48 et la MTP. Cette régulation est CD36 dépendante (Tran et al. 2011). De plus, la déficience de CD36 est associée chez l’Homme et l’animal à …

The oral lipid sensor GPR120 is not indispensable for the orosensory detectionof dietary lipids in the mouse

2014

International audience; Implication of the long-chain fatty acid (LCFA) receptor GPR120, also termed free fatty acid receptor 4 (FFAR4), in the taste-guided preference for lipids is a matter of debate. To further unravel the role of GPR120 in the "taste of fat", the present study was conducted on GPR120-null mice and their wild-type littermates. Using a combination of morphological (i.e. immunohistochemical staining of circumvallate papillae - CVP), behavioral (i.e. two-bottle preference tests, licking tests and conditioned taste aversion) and functional studies (i.e. calcium imaging in freshly isolated taste bud cells - TBC), we show that absence of GPR120 in oral cavity was not associated…

5-HT3 receptor-channels coupled with Na+ influx in human T cells: role in T cell activation.

1999

The study was conducted on a human (Jurkat) T cell line, loaded with a Na+ fluorescent probe, SBFI/AM. Serotonin and an agonist of 5-HT3 receptor-channels, 2-methyl-5HT, evoked Na+ influx, whereas the agonists of other serotonergic receptor subtypes, i.e., 5-HT1A and 5-HT1B receptors, failed to induce Na+ influx in these cells. By using 3H-BRL43694, an agonist of 5-HT3 receptor-channels, we characterized 5-HT3 lymphocyte receptors which exhibited a density (Bmax) of 300 +/- 20 fmol/10(6) cells and a Kd of 30 nM in Jurkat T cells. The T-cell 5-HT3 receptor-channel is not regulated either by the protein kinase C or by the free intracellular calcium concentrations as the agents known to activa…
