Les rafts lipidiques sont des nanodomaines membranaires enrichis en cholestérol et en sphingolipides impliqués dans la régulation de la signalisation médiée par le TCR. Néanmoins l'existence et la fonction de ces domaines sont sujettes à controverse compte tenu des difficultés expérimentales pour les étudier in vivo. En utilisant des traitements non invasifs ciblant spécifiquement la voie de biosynthèse de ces lipides, nous avons étudié l'influence de l'organisation latérale de la membrane sur l'activation lymphocytaire T. Par des approches biophysiques, nous avons démontré au sein de lymphocytes T primaires CD4+, que les molécules TCR, CD4 et Lck sont constitutivement partitionnées dans les rafts lipidiques dont est exclue CD45. De plus, c...
