Soluble LDL-receptor is induced by TNF-Α and inhibits hepatocytic clearance of LDL-cholesterol

Background and Aims: LDL-c is cleared from the circulation mainly by hepatic LDL-receptor mediated endocytosis. Defective LDL-c clearance and hence its elevation in circulation is one of the risk factors for myocardial infarction (MI). A soluble LDL-R (sLDL-R) exists in human plasma and exhibits strong correlation with circulating LDL-c and conditions that promote chronic inflammation. However, the mechanistic interplay between sLDL-R, inflammation and MI remains to be investigated.
