TGF-beta signals regulate axonal development through distinct Smad-independent mechanisms.

Abstract excerpt

Proper nerve connections form when growing axons terminate at the correct postsynaptic target. Here I show that Transforming growth factor beta (TGFbeta) signals regulate axon growth. In most contexts, TGFbeta signals are tightly linked to Smad transcriptional activity. Although known to exist, how Smad-independent pathways mediate TGFbeta responses in vivo is unclear. In Drosophila mushroom body (MB) neurons,...
