Understanding changes in high density lipoproteins during the acute phase response.
During infection and inflammation there is a cascade of reactions that occurs in the host collectively known as the acute-phase response (APR).1 Besides alterations in acute-phase reactants (plasma proteins), the APR is also associated with changes in lipoproteins.2 Increasing evidence suggests that high density lipoproteins (HDL) are a critical part of the acute phase response (APR) of the inn...
متن کاملLiver receptor homolog 1 is a negative regulator of the hepatic acute-phase response.
The orphan nuclear receptor liver receptor homolog 1 (LRH-1) has been reported to play an important role in bile acid biosynthesis and reverse cholesterol transport. Here, we show that LRH-1 is a key player in the control of the hepatic acute-phase response. Ectopic expression of LRH-1 with adenovirus resulted in strong inhibition of both interleukin-6 (IL-6)- and IL-1beta-stimulated haptoglobi...
متن کاملHDL as a Biomarker, Potential Therapeutic Target, and Therapy
Emerging evidence suggests that HDL function is not always accurately predicted by HDL cholesterol levels. The functions of HDL include reverse cholesterol transport and modulation of inflammation. These functions appear to have evolved as part of the innate immune system. In healthy individuals, in the absence of systemic oxidative stress and inflammation, HDL is anti-inflammatory. However, in...
متن کاملCholesterol efflux by acute-phase high density lipoprotein: role of lecithin: cholesterol acyltransferase.
HDL plays an initial role in reverse cholesterol transport by mediating cholesterol removal from cells. During infection and inflammation, several changes in HDL composition occur that may affect the function of HDL; therefore, we determined the ability of acute-phase HDL to promote cholesterol removal from cells. Acute-phase HDL was isolated from plasma of Syrian hamsters injected with lipopol...
متن کاملInfection and inflammation-induced proatherogenic changes of lipoproteins.
Epidemiologic studies suggest a link between infection/inflammation and atherosclerosis. During the acute-phase response to infection and inflammation, cytokines induce tissue and plasma events that lead to changes in lipoprotein. Many of these changes are similar to those proposed to promote atherogenesis. The changes of lipoproteins during infection and inflammation are reviewed with a focus ...
