Tetrahydropalmatine Alleviates Hyperlipidemia by Regulating Lipid Peroxidation, Endoplasmic Reticulum Stress, and Inflammasome Activation by Inhibiting the TLR4-NF-κB Pathway

Hyperlipidemia (HLP) is a lipid metabolism disorder that can induce a series of cardiovascular and cerebrovascular diseases, such as atherosclerosis, myocardial infarction, coronary heart disease, and stroke, which seriously threaten human health. Tetrahydropalmatine (THP) is a component of the plan...
