The removal of phospholipids and cholesterol from tissues is the major mechanism mediating the initial assembly of high density lipoproteins (HDL), as well as being the main reason HDL are thought to protect against atherosclerosis, Investigations or the mechanisms of HDL assembly and testing or novel HDL-raising agents typically involve assays to determine phospholipid and/or cholesterol removal or efflux from cultured cells. The purpose of this chapter is to describe experimental protocols that call be used in the determination of cholesterol and phospholipid efflux from cultured cells by HDL apolipoproteins for the formation of new HDL particles, and the testing of novel HDL-raising therapies in vitro. A protocol is also provided for determining the size and nature of HDL particles formed in cell-conditioned medium using two-dimensional gel electrophoresis. (c) 2005 Elsevier Inc.
