Atherosclerosis is a chronic and insidious process wherein the arterial lining is compromised by lipid and cellular infiltration. Atherosclerotic plaque progression is the underlying cause of the majority of cardiovascular diseases including myocardial infarction and strokes leading to tremendous morbidity and mortality worldwide. Understanding the pathophysiology of plaque formation and progression remains an important area of investigation both scientifically and clinically, serving as the basis for future therapeutics. Inflammatory cells, especially macrophages, play a central role in atherosclerosis. Elucidation of cellular processes that are affected in plaque macrophages has led to our understanding that among other things, aberrant lipid homeostasis and inflammation are critical to plaque progression.
Recent work on autophagy, or the process by which cells turn over long-lived organelles and proteins, has revealed that atherosclerotic macrophages manifest features of autophagy deficiency and that this deficiency is likely pathogenic as mice with selective disruption of macrophage autophagy (ATG5-null) are pro-inflammatory, have defects in lipid handling, and develop large and complex atherosclerotic lesions (Razani B, et al Cell Metab 2012; Liao X, et al Cell Metab 2012). Although the exact mechanisms of autophagy deficiency and its downstream sequelae are currently unknown, our preliminary data suggests that disruptions of autophagosome processing through lysosomes and progressive lysosomal dysfunction likely play important roles. The following projects in the lab are focused on studying the autophagolysosomal system in atherosclerosis:
1) Determining the degree of lysosomal dysfunction in Plaque Macrophages and its effect on atherogenesis
2) Investigating the potential for enhanced autophagy/lysosomal pathways to ameliorate macrophage dysfunction and atherosclerosis
3) Evaluating the pathogenic role of Inclusion Body formation in Atherosclerosis
