Mechanism Of Lpa-Induced Lipid Uptake In Macrophages, Kan Xu Aug 2013

Mechanism Of Lpa-Induced Lipid Uptake In Macrophages, Kan Xu

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 ...

Studies of the cellular pathogenesis mechanisms of pathogenic yeasts such as Candida albicans, Histoplasma capsulatum, and Cryptococcus neoformans commonly employ infection of mammalian hosts or host cells (i.e. macrophages) followed by yeast quantification using colony forming unit analysis or flow cytometry. While colony forming unit enumeration has been the most commonly used method in the field, this technique has disadvantages and limitations, including slow growth of some fungal species on solid media and low and/or variable plating efficiencies, which is of particular concern when comparing growth of wild-type and mutant strains. Flow cytometry can provide rapid quantitative information ...
