Full textThe tyrosine kinase RET is a receptor for the neurotrophic factor GDNF. The association of RET with membrane microdomains called lipid rafts is mandatory for the biological effects of GDNF. On the other hand, dominant activating mutations of RET are causally associated with the development of the multiple endocrine neoplasia type 2A (MEN2A) sydrome and we have shown that oncogenic RET does not associate with lipid rafts. Using an inducible dimerization system of the RET protein that mimics oncogenic RET MEN2A activation, we showed that specific temporal adjustment of ligand-induced AKT activation, but not ERK activation, is dependent upon a lipid raft environment and that this control step is bypassed by RET mutants. The results provide new insights in the understanding of RET oncogenic signalling pathway and unravel a role for lipid rafts in the temporal regulation of AKT activation

Full textOur result show that chronic fenoterol exposure induces hyperresponsiveness top endothelin-1 in human isolated bronchi. This effect involves three crucial factors implied in airways responsiveness : the epithelial cells, the sensory nerves, and the airway smooth muscle cells. Our immunohistochemical and biomolecular findings reveal that fenoterol-induced sensitisation of human isolated bronchi involves epithelial endothelin-1 receptors synthesis, which suggests perturbation of the epithelial regulation of airway smooth muscle contraction in response to endothelin-1. In addition, we highlighted the intracellular signalling pathways implied in fenoterol-sensitisation including sensory nerves by vanniloid receptors stimulation, and NF-kB, MAP-Kinases and protein kinases C activation

Full textThe immune response against a broad spectrum of pathogens or against tumor cells requires the CD4 + T lymphocytes activation. The triggering of T Cell Receptor (TCR) by peptide-MHC through antigen-presenting cells (APC) leads to numerous T-cell remodeling and the establishment of a specialized structure at the interface between the T lymphocyte and the APC: the immunological synapse. The synapse is the site of intense signaling events where various signaling molecules are recruited in order to amplify and diversify the signal initiated by the TCR. These signaling events are regulated by the transmembrane adapter LAT ("Linker for activation of T cells") which is present at the plasma membrane as well as in intracellular compartments. The intracellular fraction of LAT is recruited at the immune synapse and it is proposed that these vesicular compartments participate in T lymphocyte signaling. The objective of this thesis work was to determine the intracellular trafficking pathways required for the recruitment of the intracellular pool of LAT to the immunological synapse and understand the role of this transport in T cell activation and response. By silencing the expression of different intracellular transport molecules in Jurkat T cells or primary human CD4 + T lymphocytes, or by using Knock-Out (KO) mice, we have highlighted several trafficking pathways involved in the transport of LAT to the immune synapse. We have demonstrated that the recruitment of LAT to TCR activation sites requires a secretion pathway dependent on the vesicular SNARE protein VAMP7. Further analysis of the transport of LAT showed that LAT is present in recycling compartments whereas VAMP7 is mainly located in the Golgi apparatus. The study of the small GTPase Rab6 and the t-SNARE syntaxin-16 protein that are involved in the retrograde transport pathways between the recycling endosomes and the Golgi apparatus, demonstrated that this route of transport is required for the recruitment of LAT to the immunological synapse and for T lymphocyte response in vitro, ex vivo and in vivo as well. Finally, the role of intraflagellar transport protein IFT20, which has already been implicated in the transport of TCR, was analyzed in mice and also showed defects in LAT recruitment to synapse and T lymphocyte activation ex vivo and in vivo. Our results thus show that the regulation of intracellular transport plays a crucial role in T lymphocyte activation. We thus propose a model in which LAT is constitutively internalized from the plasma membrane and pursues a Golgi-dependent recycling pathway that contains the secretion machinery associated with VAMP7. This intracellular transport pathway would thus allow the polarized LAT re-secretion to the immunological synapse under activation conditions and a robust T lymphocyte response

Full textAngiotensin II (AngII) takes part to vascular smooth muscle cells (SMC) proliferation by stimulating the phosphatidylinositol 3-kinases (PI3-K) and extracellular signal-regulated kinases 1/2 (ERK) pathways. The targets of PI3-K and the regulation of the interactions possibly involved between the PI3-K/Akt and ERK pathways are not clearly defined in this cellular response. Among the molecular mechanisms, the PEA-15 (phosphoprotein enriched in astrocytes) protein, which modulates ERK nuclear localization and is an Akt substrate, seemed a good candidate. Our aims have been : 1) to identify the PI3-K targets implicated in the proliferative effect of AngII and 2) to precise the molecular interactions between the PI3-K and ERK pathways and to assess their functional consequences on the AngII proliferative response when modifying the balance between the two pathways. In rat aortic SMC and in CHO cells overexpressing the AT(lA) receptor (CHO-AT (lA)), the PI3-K and ERK pathways are independently activated but both necessary for the mitogenic response, blocked by a specific Akt inhibitor or by the expression of a dominant negative Akt mutant. Unexpectedly, Akt overexpression in CHO-AT(lA) inhibits the proliferative response of AngII. This effect is associated with a decrease of ERK transcriptional activity without modification of its phosphorylation levels. Furthermore, Akt overexpression leads to the down-regulation of the AngII-induced ERK nuclear translocation. PEA-15 overexpression also leads to ERK cytosolic relocalization and inhibition of the proliferative response in CHO-AT(lA). Moreover, Akt activation increases PEA-15 half-life. Our results show that 1) the specific activation of endogenous Akt is necessary to the proliferative response of AngII and 2) the overactivation of Akt negatively regulates ERK by stabilizing PEA-15 and retaining ERK in the cytosol, abrogating the proliferative effect of AngII
