Abstract
Mammalian neurulation is completed when the dorsolateral neural folds bend inwards, their tips make adhesive contacts across the midline, and the epithelia remodel to create a closed neural tube. Two recent papers (one by Camerer et al. in this issue of Developmental Cell) demonstrate a vital role for protease-activated G protein-coupled receptor signaling in these late closure events, opening up new avenues for exploring the molecular basis of mammalian neural tube morphogenesis.
