Chris Packard is the R&D Director of NHS Greater Glasgow & Clyde, Scotland. He holds an Honorary Professorship of Vascular Biochemistry at the University of Glasgow, and is a Consultant Clinical Scientist for NHS Greater Glasgow & Clyde Biochemistry. Over his career, Professor Packard has focussed on two aspects of atherosclerosis research, lipoprotein metabolism and how it is affected by diets and drugs, and large-scale clinical trials of lipid lowering agents. More recently his interest has widened to include investigations of emerging risk factors for coronary heart disease (CHD) and the consequences of social deprivation for health. Key contributions include evaluation of the role of the LDL receptor in vivo, the discovery of metabolic channelling in the apolipoprotein B lipoprotein delipidation cascade, and the formulation of models to explain the generation of small, dense LDL. More recent research has focussed on the metabolic consequences of insulin resistance, the causes of the dyslipidaemia in metabolic syndrome, and exploration of the mechanism of action of novel lipid lowering drugs. Professor Packard is principal investigator of the ongoing pSoBid study, an epidemiological study of the psychosocial and biological determinants of ill health and premature CHD in deprived communities in the east end of Glasgow. He was founding chairman of NEXXUS, the West of Scotland Bioscience Network which promoted community building and knowledge exchange between life sciences industry, academia and the NHS.

Keynote Lecture: Triglyceride metabolism and its clinical implications

Together, these findings have driven further study of the metabolism of TG-rich lipoproteins, which is complex and intertwined with that of cholesterol metabolism. As plasma TG levels increase, there is accumulation of large, TG-rich very low-density lipoproteins (VLDL), specifically VLDL1. These enter a delipidation cascade resulting in the formation of smaller TG-rich lipoproteins and eventually LDL. There is, however, metabolic heterogeneity within this delipidation pathway. Genetic insights have proved integral to understanding the factors that regulate TG-rich lipoprotein metabolism and identifying novel targets for therapeutic intervention.

Unlike LDL-C, however, deciphering the relationship between the decrease in plasma TG and reduction in ASCVD, is challenging given the complexity of TG-rich metabolism. Future investigation has important implications for the development of novel therapeutic approaches to TG-lowering in high-risk patients with well-controlled LDL-C levels.
