    The α1-adrenergic receptors: diversity of signaling networks and regulation

    The α1-adrenergic receptor (AR) subtypes (α1a, α1b, and α1d) mediate several physiological effects of epinephrineand norepinephrine. Despite several studies in recombinant systems and insightfrom genetically modified mice, our understanding of the physiological relevance and specificity of the α1-AR subtypes is still limited. Constitutive activity and receptor oligomerization have emerged as potential features regulating receptor function. Another recent paradigm is that ÎČarrestins and G protein-coupled receptors themselves can act as scaffolds binding a variety of proteins and this can result in growing complexity of the receptor-mediated cellular effects. The aim of this review is to summarize our current knowledge on some recently identified functional paradigms and signaling networks that might help to elucidate the functional diversity of the α1-AR subtypes in various organs

    Le plan de Nantes signĂ© en 1789 par Nicolas Sauzeau, exprime bien la dualitĂ© essentielle du quartier dont Jean-Joseph-Louis Graslin s’est fait le promoteur depuis une dizaine d’annĂ©es : un lotissement privĂ© articulĂ© avec le plan de la ville (fig. 48). La pleine valeur de l’opĂ©ration de Graslin ne pouvait Ă©viter une concertation avec la communautĂ© de ville qui prenne en considĂ©ration son projet annoncĂ© comme « vues patriotiques ». Si, dans plusieurs mĂ©moires justificatifs et dĂ©fensifs, l’écono..
