Details:
A series of molecular events initiated by the binding of a netrin protein to a receptor on the surface of the target cell, and ending with regulation of a downstream cellular process, e.g. transcription. Netrins can act as chemoattractant signals for some cells and chemorepellent signals for others. Netrins also have roles outside of cell and axon guidance.
