The Role of Lipoproteins in the Inactivation of Endotoxin by Serum

Abstract
The lipopolysaccharide(LPS)-induced release of cytokines from human monocytes can be prevented by previous interaction of serum with LPS. This inactivation is a function of lipoproteins. Here we show that LPS can be inactivated by low-density lipoproteins (LDL) as well as by high-density lipoproteins (HDL). The effects of heparin and EDTA on LPS inactivation by serum are also described.
