title: Crosstalk between reverse cholesterol transport and innate immunity.
abstract: Although lipid metabolism and host defense are widely considered to be very divergent disciplines, compelling evidence suggests that host cell handling of self- and microbe-derived (e.g. lipopolysaccharide, LPS) lipids may have common evolutionary roots, and that they indeed may be inseparable processes. The innate immune response and the homeostatic network controlling cellular sterol levels are now known to regulate each other reciprocally, with important implications for several common diseases, including atherosclerosis. In the present review we discuss recent discoveries that provide new insight into the bidirectional crosstalk between reverse cholesterol transport and innate immunity, and highlight the broader implications of these findings for the development of therapeutics.
