LDL-C augments whereas HDL-C prevents inflammatory innate immune memory

Abstract

Recent studies emphasize the importance of low-density lipoprotein cholesterol (LDL-C) in altering the hematopoieticcellcompartmentof bone marrow and of high-density lipoprotein cholesterol (HDL-C) in inhibiting metabolic endotoxemia-induced inflammation. The data suggest that these lipoproteins may exert their inflammatory or anti-inflammatory roles by modulating innate immune memory. Targeting specific LDL-C and HDL-C subfractions could therefore potentially reduce the residual risk in hepatic and cardiometabolic disease.
