Cilia and Nervous System Development and Function

Cilia are tiny microtubule-based organelles projecting from the plasma membrane of practically all cells in the body. In the past 10 years a flurry of research has indicated a crucial role of this long-neglected organelle in the development and function of the central nervous system. A common theme of these studies is the critical dependency of signal transduction of the Sonic hedgehog, and more recently, Wnt signaling pathways upon cilia to regulate fate decisions and morphogenesis. Both primar
