WebPrimary cilia are ubiquitous microtubule-based organelles that serve as signaling hubs for numerous developmental pathways, most notably the Hedgehog (Hh) pathway. Defects in the structure or function of primary cilia result in a class of diseases called ciliopathies. It is well known that primary cilia participate in transducing a Hh signal, and as such … WebMain Body. 12. Introduction to Signal Transduction. Signal Transduction • transmission of molecular signals from outside the cell into the cell via cell-surface receptors. Signal transmission is caused either by: a cascade of events or biochemical changes within the cell. o receptors that initiate biochemical changes accomplish this either by ...
