    Low plasma levels of HDL cholesterol are a risk factor for infection and hospitalization for infectious disease. Recent work suggests that inadequate levels of HDL particles of specific sizes — small and medium — account for this risk. In this Comment, we discuss the mechanistic implications of these observations and the methodologies used to quantify HDL size.

    A new study has identified a scavenger receptor-independent mechanism of atherosclerosis development by showing that LDL uptake through macropinocytosis contributes to macrophage foam cell formation and atherosclerosis development and that an FDA-approved drug that inhibits macropinocytosis inhibits atherosclerosis development in mice.

    In this Review, Borén and colleagues provide an overview of the pathways involved in triglyceride-rich lipoprotein (TRL) assembly and intravascular processing, and discuss how the dysregulation of triglyceride transport can result in hypertriglyceridaemia.

    In this Review, Gotto and colleagues summarize the evolution of our understanding of HDL structure and function, current models of atheroprotection by HDL involving reverse cholesterol transport, and their identification of a correlation between the bioavailability of free cholesterol contained in HDL and atherogenesis.

    Deficiency in the orphan G protein-coupled receptor 146 (GPR146) decreases blood lipid levels and protects against atherosclerosis in mice independently of LDL receptor activity, according to a new study.

    The scavenger receptor class B member 1 (SRB1) in endothelial cells mediates active transcellular transport of circulating LDL into the artery wall and thereby drives the accumulation of LDL in macrophages, which become foam cells and promote the development of atherosclerosis

    LDL cholesterol is an important contributor to the risk of coronary heart disease, and its measurement is central to evaluating the effects of lipid-modifying therapies. Several ‘LDL-cholesterol’ assays exist but their methodologies differ, leading to between-assay heterogeneity in values of ‘LDL cholesterol’. We advocate the need for awareness of the potential implications.

    New therapeutic strategies are needed for patients with atherosclerosis. Despite failing to reach its primary end point, a multicenter, phase II, randomized, placebo-controlled trial of RVX-208—an oral, synthetic quinazoline molecule that stimulates expression of endogenous apolipoprotein A-I—has provided somewhat encouraging results. Nevertheless, detailed investigations are still needed if we are ever to realize the full atheroprotective potential of novel HDL-targeted therapies.

    The relationship between an elevated level of LDL cholesterol (LDL-C) and increased risk of cardiovascular disease is well established. National and international guidelines are continuously being revised to recommend increasingly lower LDL-C targets for cardiovascular disease prevention. In this Review, Drs. Brautbar and Ballantyne examine the evidence and recommendations for optimal LDL-C levels and the agents currently available or under development to achieve these levels.

    Although high levels of HDL seem to be protective against clinical events from atherosclerosis, assessing the composition and function of HDL is a more-accurate approach to determine cardiovascular risk. The authors of this Review describe the atheroprotective effects of HDL, which have been attributed to its anti-inflammatory properties and role in cholesterol efflux. The relationship between impaired HDL function and cardiovascular disease is also discussed, as well as approaches to evaluate HDL functionality.

    The benefits of lowering LDL-cholesterol levels to prevent clinical events are well-recognized. However, other parameters of the lipoprotein–lipid profile are likely to contribute to cardiovascular risk and should be used in addition to the traditional lipid profile for improved assessment of cardiovascular risk. The authors of this Review discuss alternative and emerging lipid parameters associated with cardiovascular disease that could identify patients at high risk and those who will benefit most from lipid-lowering therapy.
