Tetrahydropalmatine promotes macrophage autophagy by inhibiting the AMPK/mTOR pathway to attenuate atherosclerosis.

Atherosclerosis (AS) is a chronic progressive arterial disease that is associated with macrophage autophagy and AMP-activated protein kinase (AMPK)/mechanistic target of the rapamycin (mTOR) pathway. Tetrahydropalmatine (THP) can activate AMPK-dependent autophagy. We aim to study the mechanism of macrophage autophagy mediated by THP in the treatment of AS via the AMPK/mTOR pathway.
