Masters Theses

Cardiovascular disease, currently the leading cause of mortality throughout the developed countries, is mainly caused by atherosclerosis, which is recognized as a chronic inflammatory disease. Atherosclerotic plaques are characterized by accumulations of lipid in arterial walls together with infiltration of macrophages. These macrophages differentiate from monocytes which transform into foam cells through phagocytizing various forms of lipid, are believed to be the main component of early atherosclerotic lesions.

Lysophosphatidic acid (LPA), a potent bioactive lipid, regulates a broad range of cellular functions in various cell types. In our findings, LPA-induced macrophages may enhance the lipid uptake effect in both J774A ...
