    Aquaporin-4 (AQP4) is essential for the glymphatic system's function in clearing toxic proteins like α-synuclein from the brain.

  • 2

    Glymphatic dysfunction is implicated in Parkinson's disease, affecting α-synuclein propagation and clearance dynamics.

  • 3

    Injection of α-syn preformed fibrils reduces AQP4 endfoot complex expression but enhances glymphatic function in response to increased α-syn load.

  • 4

    Acute glymphatic inhibition decreases brain-to-CSF clearance of misfolded α-syn, exacerbating α-syn pathology and motor deficits.

  • 5

    The study suggests that dysregulation of AQP4 may contribute to glymphatic impairment associated with Parkinson's disease.
