AMPK activation regulates neuronal structure in developing hippocampal neurons

Highlights • AMPK subunits upregulated during neuronal development. • Knockout of either AMPK catalytic subunit does not affect basal axon or dendrite growth. • Activation of AMPK during development impairs axogenesis and dendrite growth and arborization. • Activation of AMPK inhibits the positive r...

Description
Summary:Highlights • AMPK subunits upregulated during neuronal development. • Knockout of either AMPK catalytic subunit does not affect basal axon or dendrite growth. • Activation of AMPK during development impairs axogenesis and dendrite growth and arborization. • Activation of AMPK inhibits the positive regulators of dendritic growth Akt and mTOR.
