Le cil primaire est souvent associé aux phases G0 et G1 du cycle cellulaire de la plupart des cellules. Ainsi, des études récentes montrent que sa formation et sa résorption sont étroitement liées à des acteurs moléculaires du cycle cellulaire, comme par exemple Aurora A ou PLK1 (polo-like kinase 1). De plus, sa résorption semble être critique pour la progression de la phase S et la détermination cellulaire, notamment dans le cas des cellules souches neurales. Enfin, le cil primaire agit comme une antenne cellulaire permettant de transmettre des signaux de nombreuses voies de signalisation qui, à leur tour, contribuent au destin cellulaire.
Abstract
The primary cilium is often associated with the phases G0 and G1 of the cellular cycle in most of the cells. So, recent studies show that its formation and its resorption are closely linked to molecular actors of the cellular cycle, as for example Aurora A or PLK1 (polo-like kinase 1). Furthermore, its resorption seems to be critical for the progress of the phase S and the cellular determination, in particular in the case of neural stem cells. Finally, the primary cilium acts as a cellular antenna allowing to transmit numerous signal pathways which, in their turn, contribute to the cellular fate.
