Cilia organize ependymal planar polarity.
Multiciliated epithelial cells, called ependymal cells, line the ventricles in the adult brain. Most ependymal cells are born prenatally and are derived from radial glia. Ependymal cells have a remarkable planar polarization that determines orientation of ciliary beating and propulsion of CSF. Disruption of ependymal ciliary beating, by injury or disease, results in aberrant CSF circulation and...
متن کاملAcute kidney injury and aberrant planar cell polarity induce cyst formation in mice lacking renal cilia.
Polycystic kidney disease (PKD) is an inherited disorder that is characterized by the accumulation of cysts in the renal parenchyma and progressive decline in renal function. Recent studies suggest that PKD arises from abnormalities of the primary cilium. We have previously shown that kidney-specific inactivation of the ciliogenic gene Kif3a during embryonic development produces kidney cysts an...
متن کاملIntraflagellar transport proteins are essential for cilia formation and for planar cell polarity.
The highly conserved intraflagellar transport (IFT) proteins are essential for cilia formation in multiple organisms, but surprisingly, cilia form in multiple zebrafish ift mutants. Here, we detected maternal deposition of ift gene products in zebrafish and found that ciliary assembly occurs only during early developmental stages, supporting the idea that maternal contribution of ift gene produ...
متن کاملMicrotubules Enable the Planar Cell Polarity of Airway Cilia
BACKGROUND Airway cilia must be physically oriented along the longitudinal tissue axis for concerted, directional motility that is essential for proper mucociliary clearance. RESULTS We show that planar cell polarity (PCP) signaling specifies directionality and orients respiratory cilia. Within all airway epithelial cells, a conserved set of PCP proteins shows interdependent, asymmetric junct...
متن کاملPlanar Cell Polarity: Microtubules Make the Connection with Cilia
Despite decades of research there are still basic aspects of planar cell polarity that are not well understood. Recent work in mouse tracheal epithelial cells links microtubules with both establishing asymmetry as well as responding to this asymmetry to coordinate cellular orientation.
