Primary cilia
The primary cilium was first so named by Sergei Sorokin in 1968.[1] Since the discovery of primary cilium in 1898 by Zimmerman, three major hypotheses for their function have been put forth. The first is that primary cilia are vestigial organelles inherited from an ancestor whose cells had motile cilia and now are of no purpose in multicellular organisms. The second is that they are involved in...

lization. This independence of calcium and PGE 2 has been reported previously and suggests that there are multiple mechanisms by which bone cells sense their mechanical environment. These findings are currently in press in the Primary cilia mediate mechanosensing in bone cells by a calcium-independent mechanism. by oscillatory fluid flow via intracellular calcium mobilization and activation of ...
متن کاملINPP5E regulates phosphoinositide-dependent cilia transition zone function
Human ciliopathies, including Joubert syndrome (JBTS), arise from cilia dysfunction. The inositol polyphosphate 5-phosphatase INPP5E localizes to cilia and is mutated in JBTS. Murine Inpp5e ablation is embryonically lethal and recapitulates JBTS, including neural tube defects and polydactyly; however, the underlying defects in cilia signaling and the function of INPP5E at cilia are still emergi...
متن کاملPrimary cilia: cellular sensors for the skeleton.
The primary cilium is a solitary, immotile cilium that is present in almost every mammalian cell type. Primary cilia are thought to function as chemosensors, mechanosensors, or both, depending on cell type, and have been linked to several developmental signaling pathways. Primary cilium malfunction has been implicated in several human diseases, the symptoms of which include vision and hearing l...
متن کاملHIF Stabilization Weakens Primary Cilia
Although solitary or sensory cilia are present in most cells of the body and their existence has been known since the sixties, very little is known about their functions. One suspected function is fluid flow sensing- physical bending of cilia produces an influx of Ca++, which can then result in a variety of activated signaling pathways. Defective cilia and ciliary-associated proteins have been ...
