The macrophage lectin-like oxidized LDL receptor-1 (LOX-1), also called the oxidized low-density lipoprotein receptor 1 (OLR1), is currently thought to aid in atherosclerotic disease progression; therefore metabolic studies have potential to both provide mechanistic validation for the role of LOX-1 in disease progression and provide valuable information regarding biomarker strategies and clinical imaging. One such mechanistic study is the upregulation of LOX-1 by methylated bacterial DNA and deoxy-cytidylate-phosphate-deoxy-guanylate-DNA (CpG)-DNA exposure. CpG-DNA is known to promote oxidative burst responses in macrophages, due to its direct binding to toll-like receptor 9 (TLR9) leading to the initiation of an NF-<i>κ</i>B mediated immune response. In addition to the upregulation of macrophage LOX-1 expression, these studies have also examined the macrophage metabolic response to murine LOX-1/OLR1 antibody exposure. Our data suggests the antibody exposure effectively blocks LOX-1 dependent oxLDL metabolic activation of the macrophage, which was quantified using the multianalyte microphysiometer (MAMP).

We also studied the effect of apoA-I modification by homocysteine, a risk factor for atherosclerosis, on cholesterol efflux capacity in different states of cells. The cholesterol efflux capacity of apoA-I was greatly influenced by the extent of differentiation of THP-1 cells and attenuated by excessive foam cell formation. N-Homocysteinylated apoA-I indicated a lower cholesterol efflux capacity than normal apoA-I in the optimized condition, whereas no significant difference was observed in the cholesterol efflux capacity between apoA-I in the excessive cell differentiation or foam cell formation states.

Materials and Methods. Patients (n = 299) consecutively included in the ongoing Omega-3 fatty acids in elderly patients with myocardial infarction (OMEMI) trial were investigated. Peak TnT was registered during the hospital stay. Serum fatty acid analysis was performed 2–8 weeks later. Results. No significant correlations between peak TnT levels and any of the n-3 PUFAs were observed.
