TSPO polymorphism in individuals with alcohol use disorder: Association with cholesterol levels and withdrawal severity.

ABSTRACT: The translocator protein (TSPO) transports cholesterol into mitochondria and is involved in steroidogenesis. The TSPO polymorphism rs6971 influences binding of cholesterol and other TSPO ligands including positron-emission tomography (PET) imaging radiotracers. Although it is recognized that alcohol increases plasma high-density lipoproteins (HDLs), its effects on total cholesterol and triglycerides along with its relationship to TSPO genotype have not been assessed. Here, we evaluated whether plasma cholesterol and triglycerides are disrupted in alcohol use disorder (AUD) and their association with rs6971 in 932 AUD participants (DSM IV or 5) and 546 controls. AUD participants compared with controls had significantly higher plasma levels of total cholesterol, HDL, and triglycerides, but n
