Abstract: The primary cilia， centrosome-based， specialized organelles that protrude from the cell membrane of most types of quiescent and differentiated mammalian cells. Primary cilia integrate multiple signals into specific outputs， therefore， defects of primary cilia can lead to a series of human diseases called ciliopathies. Here， we review the latest advances on primary cilia structure， ciliogenesis and disassembly process， and ciliary protein degradation pathway， and discuss the relationship between defects of primary cilia and ciliopathy， providing some cues for the diagnosis and treatment of ciliopathy.
