(Submitter supplied) In atherosclerosis, several immune cells are involved in plaque formation. Foam cell formation is a major cellular process in atherosclerotic lesion. It is important to understand which cells participate in foam cell formation. To characterize the immune cells and foam cells in atherosclerotic aorta, we performed single cell RNA sequencing of aortic CD45+ leukocytes from Ldlr-/- mice and foamy cells from ApoE-/- mice. more...

(Submitter supplied) Macrophages in atherosclerotic aorta are major population in lesion and contributes to lesion formation by becoming foam cells. To investigate in vivo transcriptome profiles of those macrophages, we extracted foamy and non-foamy macrophages from atherosclerotic aorta using lipid probe-based flow cytometry sorting. Our data indicates that intima non-foamy and foamy macrophages show different mRNA expressions. more...

(Submitter supplied) We have carried out a systems biology investigation of regulators controlling arterial plaque macrophage transcriptional changes in response to lipid lowering, in the Reversa mouse model of plaque regression in which poly I:C injections induce recombination-mediated inactivation of Mttp in the liver and (when combined with a switch to chow diet) restore normal lipid levels in an Ldlr-/-Apob100/100 mouse (Lieu et al., 2003, Circulation, v.107(9), pp.1315-21). more...

(Submitter supplied) Atherosclerosis is a systemic and chronic inflammatory disease propagated by monocytes and macrophages. Yet, our knowledge on how transcriptional profiles of these cells evolve in time and space is limited. We aimed at characterizing gene expression changes in site-specific macrophages, i.e. atherosclerotic aorta versus remote peritoneal cavity, and in circulating monocytes during the course of atherosclerosis initiation and progression in Apoe deficient mice. more...

(Submitter supplied) The aim of this study was to analyze the transcriptome of diverse Nrf2-deficient macrophage subpopulations from murine atherosclerotic aortas. Mice with transcriptionally inactive Nrf2 in Cdh5-expressing cells (Nrf2Cdh5tKO) were used in the experiments. These mice lack transcriptional Nrf2 activity in endothelial cells, but also in a proportion of leukocytes. We confirmed that the bone marrow-derived and tissue-resident macrophages isolated from Nrf2Cdh5tKO mice exhibit a significant decline in Nrf2 activity. more...

(Submitter supplied) Epigenetic modifications of the genome, including DNA methylation, histone methylation/acetylation and noncoding RNAs, have been reported to play a fundamental role in regulating immune response during the progression of atherosclerosis. SETDB2 is a member of the KMT1 family of lysine methyltransferases and members of this family typically methylate histone H3 Lys9 (H3K9), an epigenetic mark associated with gene silencing and previous studies have shown SETDB2 is involved in innate and adaptive immunity, the pro-inflammatory response and hepatic lipid metabolism. more...

(Submitter supplied) Atherosclerotic plaques are complex tissues composed of a heterogeneous mixture of cells. However, our understanding of the comprehensive transcriptional and phenotypical landscape of the cells within these lesions is limited. To characterize the landscape of human carotid atherosclerosis in greater detail, we combined cellular indexing of transcriptomes and epitopes by sequencing (CITE-seq) and single-cell RNA sequencing (scRNA-seq) to classify all cell types within lesions (n=21; 13 symptomatic) to achieve a comprehensive multimodal understanding of the cellular identities of atherosclerosis and their association with clinical pathophysiology. more...

Using single-cell RNA-sequencing of enriched fraction of adventitial mesenchymal cells, we defined and quantified novel markers in healthy murine adventitia. PHATE dimensionality reduction and subsequent clustering characterized heterogeneity, predicting three novel differentiation trajectories. Gene ontology (GO) analysis supported divergent functional profiles, related to vascular development, antigen presentation and collagen fibril organization. more...
