Control of lipopolysaccharide-high-density lipoprotein interactions by an acute-phase reactant in human serum

Murine serum glycoprotein gp70 behaves as an acute phase reactant

A single intraperitoneal injection of bacterial lipopolysaccharide (LPS) or its lipid A component induced high levels of glycoprotein, gp70, in sera of several strains of mice within 24 h. This serum gp70 response induced by LPS was independent of the activation of B cells and the presence of T cells. However, serological and immunohistochemical studies demonstrated the production of gp70 by he...

Isolation of a lipopolysaccharide-binding acute phase reactant from rabbit serum

This report describes the purification of an acute phase reactant from acute phase rabbit serum, which endows normal serum with the properties of acute phase serum, insofar as LPS is concerned. The acute phase reactant is referred to as LPS-binding protein, or LBP. LBP was purified approximately 2,000-fold by chromatography of acute phase serum on Bio-Rex 70 and Mono-Q resins. The resulting pre...

Study of Serum Paraoxonase and High Density Lipoprotein Fractions in Diabetes

Objective: Significant alteration in lipid profile and antioxidant system occurs in response to diabetes mellitus (DM). Paraoxonase (PON) is a family of three enzymes PON1, PON2 and PON3 associated with high density lipoprotein (HDL). The HDL in human plasma consists of two main sub-fractions HDL2C and HDL3C. We studied the HDL subclasses and HDL associated enzyme paraoxonase with respect to di...

Serum High Density Lipoprotein Cholesterol

Lipoprotein (a) as an acute phase reactant in patients on chronic hemodialysis.

Lipoprotein (a) [Lp(a)], is an independent risk factor for atherosclerotic cardiovascular disease in patients on chronic hemodialysis. A low concentration of high density lipoprotein cholesterol (HDL-C) and serum albumin are another potential risk factors. The purpose of this study was to explore in patients on chronic hemodialysis, whether Lp(a) elevated levels are influenced by activated acut...
