Joset, P; Wacker, A; Babey, R; Ingold, E A; Andermatt, I; Stoeckli, E T; Gesemann, M (2011). Rostral growth of commissural axons requires the cell adhesion molecule MDGA2. Neural Development, 6:22.



Directed axonal growth of dorsal commissural interneurons requires an elaborate mixture of instructive (guidance) and permissive (outgrowth supporting) molecules. While Wnt and Sonic hedgehog (Shh) signalling pathways have been shown to specify the growth direction of post-crossing commissural axons, our study now provides evidence that homophilic MDGA2 interactions are essential for axonal extension along the longitudinal axis. Interestingly, so far each part of the complex axonal trajectory of commissural axons uses its own set of guidance and growth-promoting molecules, possibly explaining why such a high number of molecules influencing the growth pattern of commissural interneurons has been identified.
