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.
Insights
Protease-activated G protein-coupled receptor signaling is crucial for closing the neural tube in mammals. This discovery offers new insights into the molecular mechanisms of neural tube development.
Area of Science:
- Developmental Biology
- Molecular Biology
- Cell Biology
Background:
- Mammalian neurulation involves the inward bending of neural folds and epithelial remodeling to form a closed neural tube.
- Late closure events are critical for successful neural tube morphogenesis.
Discussion:
- Two recent studies highlight the significant role of protease-activated G protein-coupled receptor (GPCR) signaling in mammalian neural tube closure.
- This signaling pathway influences the adhesive contacts and epithelial remodeling necessary for forming the neural tube.
Key Insights:
- Protease-activated GPCR signaling is essential for the final stages of mammalian neural tube formation.
- Understanding this pathway provides a deeper insight into the molecular basis of neural tube morphogenesis.
Outlook:
- Further research into protease-activated GPCR signaling can reveal novel therapeutic targets for neural tube defects.
- This work opens new avenues for exploring the complex molecular mechanisms underlying embryonic development.

Notch Signaling Pathway
The Notch gene came into the limelight in 1914 after the discovery that its mutation in Drosophila melanogaster leads to a serrated (or "notched") wing margin phenotype. It was not until 1985...
