In the nervous system, cilia dysfunction perturbs the circulation of the
cerebrospinal fluid, thus affecting neurogenesis and brain homeostasis. A role
for planar cell polarity (PCP) signaling in the orientation of cilia (rotational
polarity) and ciliogenesis is established. However, whether and how PCP regulates
cilia positioning in the apical domain (translational polarity) in radial
progenitors and ependymal cells remain unclear. By analysis of a large panel of
mutant mice, we show that two PCP signals are operating in ciliated cells. The
first signal, controlled by cadherin, EGF-like, laminin G-like, seven-pass,
G-type receptor (Celsr) 2, Celsr3, Frizzled3 (Fzd3) and Van Gogh like2 (Vangl2)
organizes multicilia in individual cells (single-cell polarity), whereas the
second signal, governed by Celsr1, Fzd3, and Vangl2, coordinates polarity between
cells in both radial progenitors and ependymal cells (tissue polarity). Loss of
either of these signals is associated with specific defects in the cytoskeleton.
Our data reveal unreported functions of PCP and provide an integrated view of
planar polarization of the brain ciliated cells.
