Abstract

The main topic of this thesis is the effect of stressors, in or outside of the cell, on atherosclerosis. In atherosclerosis, multiple cell types are important: inflammatory cells that clean up the growing pool of lipids and matrix-producing cells that produce matrix. The latter is essential in preventing the formation of blood clots and thus decreasing the risk of developing cardiovascular disease. This dissertation research investigated numerous stressors, such as oxygen and cholesterol levels, and what the effect of those is on earlier mentioned cells. This thesis found that autophagy, as a response to lipids, works protective in atherosclerosis. While it also shows that vast amounts of lipids lead to cell death in inflammatory cells, which can lead to cardiovascular disease. Low oxygen levels can also manifest this in inflammatory cells, which in turn can lead to matrix production by matrix-producing cells. This thesis shows that a variety of stressors can have divergent effects on atherosclerosis, in a cell-specific manner.
