Mouse tracheal epithelial cells produce hundreds of motile cilia, all of which are Levomilnacipran arranged in parallel along the apical surface.Interestingly, a ciliary adhesion complex consisting of focal adhesion proteins was shown to localize to basal bodies at the appendage and rootlet, conferring connections with the apical and subapical cytoskeletons.Disruption of this complex led to docking and spacing defects, resulting in clustered basal bodies. It is likely that mechanisms involving the actin cytoskeleton in basal body migration and ciliogenesis are conserved between primary cilia and MCC motile cilia, but further studies are needed.The actin cytoskeleton facilitates the transport of vesicular cargo throughout the cell, driven by myosin motors along actin cables.Cozymase Assuming that myosinmediated delivery of ciliary cargo requires polymerized actin, the model that actin polymerization negatively regulates primary cilia is difcult to understand.Furthermore, whether these roles are duplicated during ciliary disassembly has not been studied directly.Actin could play a role in facilitating the transport of ciliary proteins and membrane away from the cilium for recycling or degradation and in driving migration of the basal body basally from the plasma membrane.Whether these processes require polymerization or depolymerization of actin is not understood.Conversely, the primary cilium may regulate canonical roles of actin in cellular processes that include cell migration, shape, and interactions with neighboring cells and the extracellular matrix.Furthermore, the primary cilium, like other actinassociated adhesion structures, is a marker of cell polarity, as it generally forms on the apical surface in polarized cells.As such, the regulation of the cilium and other polarity markers may be similar.The cilium, which coordinates multiple migrationrelated signaling pathways, orients along the axis of migration and in most migratory cell types the centrosome is positioned between the nucleus and the leading edge, where it is thought to coordinate cytoskeletal dynamics.In general, defects in ciliary organization and function result in impaired cell migration, wound repair, development, and morphogenesis. In neuronal development, ciliary signaling is required for proper cell migration.Joubert syndrome, a ciliopathy characterized by defects in neuronal migration and brain development such as microcephaly, results from disruption of ciliary signaling. In ciliated breast cancer cells, knockdown of the estrogen receptor corepressor SPEN results in loss of the primary cilium and impaired cell migration. In MDCK cells, the canonical ciliary protein IFT may play ciliumindependent roles by involvement in targeting protein to the leading edge during cell migration. In the corneal endothelium, the basal body of primary cilia transiently repositions away from the nucleus and toward the leading edge of cells during wound repair; upon completion of wound closure, cilia are lost and centrosomes migrate toward the nucleus. Primary ciliary signaling appears to regulate cell migration through modulating actin dynamics, targeting of polarity proteins to the leading edge, and cellsubstrate focal adhesion formation. The bestcharacterized ciliary signaling pathway in cell migration is the PDGFAAPDGFR pathway. PDGFAA ligand activates its receptor PDGFR at the ciliary membrane and at focal adhesions.Turnover of integrinbased focal adhesions is critical for migration.Disruption of this pathway reduces cell migration and endothelial barrier integrity. The retinitis pigmentosa protein RPGR localizes to primary cilia and is required for primary cilia, actin dynamics, and focal adhesion turnover, although a migration defect was not reported.
