Abstract:
Afin de mettre en évidence des protéines de l’hôte nécessaires au développement des formes intra-hépatiques de Plasmodium chez l’Homme, nous avons utilisé comme outil l’ARN interférence, pour atténuer l’expression de 6080 gènes de l’hôte dans le modèle d’infection HepG2-A16/hCD81EGFP / P. Yoelii. Après deux étapes de sélection successives, vinqt-sept gènes ont été retenus. L’invalidation de ces gènes par ARNi induit une diminution de l’infection d’au moins 30% par rapport aux contrôles sans altérer la viabilité des cellules hôtes. Nous en avons étudié cinq d’entre eux : ALDH18A1, LIPG, TMEM30A

Abstract:
Calcium-activated chloride channels (CaCCs) are a class of the ligand-gated channels involved in numerous cellular functions. In vascular smooth muscle, these ion channels couple agonist-induced calcium-release from the sarcoplasmic reticulum to membrane depolarisation and vasoconstriction. For this reason, CaCCs have been suggested as a potential molecular target to treat a range of vascular disorders. These ion channels, however, have not been yet explored as a drug target because their molecular identity has been elusive and their pharmacology has been restricted to compounds with low poten

Abstract:
Calcium-activated chloride channels (CaCCs) are ubiquitously expressed in a plethora of cell types and, consequently, are involved in numerous cellular processes as diverse as epithelial secretion, regulation of cardiac excitability and smooth muscle contraction. Current pharmacology of CaCCs is limited to compounds with low potency and poor selectivity. The lack of knowledge surrounding the molecular identity of the CaCC has greatly hindered the development of more specific drugs and has impaired our understanding of the channel physiology and biophysics.

Abstract:
Introduction: Failure of coronary blood vessels to adequately supply cardiac myocytes with oxygen underlies ischaemic heart disease and ultimately myocardial infarction. Therefore, it is important to determine the factors that regulate coronary blood flow. Activation of Ca2+-activated chloride channels depolarises vascular smooth muscle cells sufficiently to cause Ca2+ influx through voltage-dependent channels and contraction of the cell. TMEM16A is the main molecular candidate for these channels. Hypothesis: TMEM16A is expressed in rat coronary arteries where it regulates vascular smooth musc

Abstract:
Proteins of anoctamin (TMEM16) family are the candidate subunits for Ca2+- activated Cl- channels (CaCC). In recent years, studies have shown that anoctamin-1 (TMEM16A or ANO1) plays important physiological roles in processes including epithelial fluid secretion, muscle contraction and olfactory transduction. How the Ca2+ regulates the activity of ANO1 in different tissue is still not clear. In this study, I showed that the excitatory CaCC in nociceptors (small-diameter sensory neurons that are responsible for transmission of painful stimuli) was activated by the release of Ca2+ from the 1, 4,

La mucoviscidose (CF pour Cystic Fibrosis) est la conséquence de la mutation du gène codant pour le canal chlorure CFTR. Une des stratégies thérapeutiques proposées pour compenser la déficience de CFTR serait de stimuler une voie alternative à CFTR de sécrétion d'ions chlorures. En 2008, le canal ANO1 a été identifié comme CaCC (canal chlorure activé par le calcium) et alors proposé comme cible thérapeutique dans le contexte de la mucoviscidose.

There is evidence of its trimerization and even tetramerization.
