MAP6-mediated microtubule stabilization as therapeutic target

Mechanistic description

Aberrant MAP6 function may contribute to tau-independent cytoskeletal defects in neurodegeneration, and stabilizing MAP6-microtubule interactions pharmacologically could compensate for Tau pathology

Prediction: Small molecules enhancing MAP6-microtubule binding will ameliorate cytoskeletal defects in tau knockout neurons and improve neuronal survival in amyloid toxicity models
