Background: The phosphatase PTEN is implicated in suppressing neuroregeneration following injury. Results: Chemorepulsion of axons by distinct cues, but not chemoattraction, correlates with PTEN activity, depression of phosphatidylinositol signaling, and remodeling of integrin adhesions. Conclusion: PTEN mediates chemorepulsion selectively. Significance: Suppressing PTEN activity may block repulsion by negative cues after injury while permitting attractive guidance of regenerating axons.
