L’hypertension rénovasculaire est caractérisée par une sténose de l’artère rénale et des taux plasmatiques élevés de rénine, du fait du recrutement des cellules productrices de rénine le long de l’artériole afférente. Cette augmentation du nombre de cellules myoépithélioïdes est due principalement à la différenciation des cellules musculaires lisses préexistantes qui acquièrent un phénotype sécrétoire. Pour comprendre les mécanismes moléculaires impliqués dans ce recrutement, nous avons utilisé le modèle d’hypertension rénovasculaire 1 clip-2 reins, établi chez le rat Lewis. Les artérioles rénales ont été isolées par une suspension magnétique de fer. L’analyse protéomique différentielle a été effectuée par électrophorèse bi-dimensionnelle et l’identification des protéines par spectrométrie de masse. La protéine la plus surprenante identifiée par spectrométrie de masse est la troponine T qui est sous-exprimée dans le rein hypoperfusé. Les expériences en microscopie confocale ont montré que la troponine T n’était exprimée que dans les cellules type musculaire lisse dans le rein et absente des cellules myoépithélioïdes.Mots clés : hypertension rénovasculaire, rénine, appareil juxtaglomérulaire, protéomique, cellules musculaires lisses Abstract Renovascular hypertension is characterised by stenosis of the renal artery and high plasma renin levels due to the recruitment of renin-producing cells along the afferent arterioles. This increase in myoepithelioid cells is mainly a result of the differentiation of existing smooth muscle cells with acquisition of a secretory phenotype. To understand the molecular mechanisms involved in this recruitment, we used the model of renovascular hypertension known as the two-kidney, one-clip model in the Lewis rat. Renal arterioles were isolated using magnetised iron suspension. Differential proteomic analysis was performed using two-dimensional electrophoresis gel followed by mass spectrometry for identification. The most striking protein revealed by proteomics is troponin T, which is down-regulated in the afferent arterioles of the clipped kidney. Confocal microscopy showed that troponin T is specific to the smooth muscle phenotype and absent in the myoepithelioid phenotype.Keywords: renovascular hypertension, renin, juxtaglomerular apparatus, proteomics, smooth muscle cells Texte reçu le 29 juillet 2003 ; accepté le 9 décembre 2003 [ABSTRACT FROM AUTHOR]
