Abstract

Homocysteine may pose an oxidant challenge in vivo and increase the risk of cardiovascular disease through this route. However, most in vitro studies have used unphysiological concentrations and forms of homocysteine. We will use a model system which will simulate conditions in vivo in that human endothelial cells in culture will export homocysteine with consequent autoxidation and the associated generation of reactive oxygen species, quantified through electron spin resonance spectroscopy. Oxidative modification of human low density lipoprotein in this system will be measured and the functional relevance of this determined through uptake studies with human monocyte-derived macrophages and the expression of the scavenger receptor. (Joint with grants 50/C16643 and 316/C16648).
