Abstract: | Migrating neuronal cells are directed to their final positions by an array of guidance cues. It has been shown that guidance molecules such as UNC-6/Netrin and SLT-1/Slit play a major role in controlling cell and axon migrations along the dorsal-ventral body axis. Much less is known, however, about the mechanisms that mediate migration along the anterior-posterior (AP) body axis. Recent research in Caenorhabditis elegans has uncovered an important role of the Wnt family of signalling molecules in controlling AP-directed neuronal cell migration and polarity. A common theme that emerges from these studies is that multiple Wnt proteins function in parallel as instructive cues or permissive signals to control neuronal patterning along this major body axis. |
