Xenon + propofol (Molecular Neurobiology, 2020): In human neural stem cell–derived neurons, prolonged propofol (50 µM, 16 h) reduced the neuronal marker PSA‑NCAM and caused morphologic damage, while co‑exposure to xenon (33%) prevented PSA‑NCAM loss and promoted its re‑expression after enzymatic removal; xenon alone was not harmful. The findings suggest xenon may mitigate anesthetic‑induced neurotoxicity by supporting PSA‑NCAM–related neuronal plasticity.
