Phenotype Changes of Circulating Monocytes in a Hypercholesterolemic Swine Model of Coronary Artery Disease

Abstract: Objective: Inflammation and immunity activation play a key role in atherosclerosis (ATS) onset and progression. Aim of this study was to investigate the relationships between phenotype of circulating monocytes and coronary artery disease (CAD) development in a histologically well-characterized swine model of ATS. Methods:Blood samples were obtained from 6 animals at baseline and after 16 weeks high fat cholesterolenriched diet. Flow cytometry monocyte identification was performed (CD172a marker). Adhesion (CD1… Show more

“…Our examination of day 7 post-MI captures only a narrow slice of the entire wound healing process, and effects of CBSC therapy on cell types like neutrophils and monocytes, which are critical to the immune response to cardiac wound healing, may not be accurately represented looking at this time point. Although the analysis of swine cardiac immune cells by flow cytometry may not yet be commonplace in basic cardiovascular research, all immune cell markers used in this study were taken directly from previously established cell-membrane markers of porcine immune cell populations (71)(72)(73)(74). Lastly, the pig heart is a vast organ compared with a mouse or rat, and although we have taken targeted approaches in our analysis of the infarct, it is not feasible to analyze the pig heart as thoroughly as a mouse or rat heart.…”
