Project description: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. The single cell RNA-seq analyses revealed the heterogeneity of aortic macrophages and foam cells in atherosclerotic aorta.

Project description:Macrophages in atherosclerotic aorta are major population in lesion and contributes to lesion formation by becoming foam cells. To investigate in determine diversity of arterial macrophage, we extracted aorta intima resident macrophages (CD11c+ MHC II+ CD64+ macrophages from C57BL/6 mice, as well as adventitia macrophages from atherosclerotic aorta (which complement our prior submissions of foamy and non-foamy intima macrophage). Our data identify unique gene expression signatures for these different macrophage populations in the aorta.

Project description:We have applied single cell RNA sequencing (scRNA-seq) as an unbiased transcriptomics to characterize aortic immune cells in atherosclerosis. The scRNA-seq analysis revealed macrophage heterogeneity at the single-cell level in mouse atherosclerotic aorta.

Project description:Atherosclerosis is modulated by immune cells. Understanding the diversity and heterogeneity in the aorta in steady state, as well as during different stages of disease will help to determine mechanisms promoting disease progression. To characterize the immune cells, we performed single cell RNA sequencing of aortic CD45+ leukocytes from C57BL/6 (WT) on chow diet and early disease Ldlr-/- mice fed high fat diet (HFD) for 21-days. The single cell RNA-seq analyses revealed the heterogeneity of aortic macrophages in steady state and early atherosclerotic disease.

Project description:In atherosclerosis progression and regression, monocytes or monocyte-derived macrophages are the major immune cells in the plaque. It is important to understand the fate and characteristics of monocyte/macrophage during the plaque progression and regression. To characterize the fate of monocytes/macrophages, we performed single cell RNA sequencing of fate-mapped aortic CX3CR1-derived monocytes/macrophages from Cx3cr1CreERT2-IRES-YFP/+Rosa26floxed-tdTomato/+ mice with AAV-PCSK9 injection and fed a Western Diet. The single cell RNA-seq analyses revealed the heterogeneity of aortic macrophages and identified a stem-like cell cluster in atherosclerotic aorta.

Project description:C.pn potentiated hyperlipidemia-induced inflammasome activity in cultured macrophages and in foam cells in atherosclerotic lesions of Ldlr–/– mice. We discovered that C.pn-induced extracellular IL-1β triggers a negative feedback loop to inhibit GPR109a and ABCA1 expression and cholesterol efflux leading to accumulation of intracellular cholesterol and foam cell formation. Gpr109a and Abca1 were both upregulated in plaque lesions in Nlrp3–/– mice in both hyperlipidemic and C.pn infection models. We sued microarrays to detail the gene expression underlying C.pn and ox-LDL treatment on mice periteneal macrophages to study the regulating of ABCA1 related genes with NLRP3 manutation

Project description:Crosstalk between the diseased atherosclerotic aorta and the peripheral nervous system
| PRJNA368642 | ENA
Project description:The goal of these studies was to delineate mechanisms of crosstalk between the atherosclerotic arterial wall of the aorta and the peripheral nervous system (PNS) in aged hyperlipidemic ApoE-deficient mice. We had observed by immunohistochemistry and morphometry that axon density of the PNS in adventitia segments that were located adjacent to advanced atherosclerotic plaques of aged hyperlipidemic ApoE-deficient mice were markedly higher than those adventitia segments that did not show adjacent atherosclerotic plaques in the intima layer. It is noteworthy in this connection that neither the media nor the intimal layer are innervated by axon endings. However, the adventitia layer of arteries is a conduit for axons and nerves of the PNS connecting the peripheral ganglia and peripheral organs including the spleen. In addition, we discovered (see references below) that atherosclerosis is sensed by the immune system of aged ApoE-deficient mice resulting in the formation of artery tertiary lymphoid organs in the adventitia layer of the arterial wall. To examine potential molecular mechanisms of the crosstalk between the disease aorta and the PNS, we isolated adventitia tissues and media tissues from aortas of ApoE-deficient mice and used wild-type mice as controls. Moreover, we observed that the sympathetic nervous system paraaortic and periaortic ganglia in aged ApoE-deficient but not of aged wild-type mice were infiltrated by leukocytes indicating that atherosclerosis is associated with major alterations of the PNS including axonogenesis and ganglionitis. To identify potential molecules involved in the crosstalk, we isolated respective tissues (media, adventitia, ganglia) by laser capture microdissection and generated large scale mRNA expression arrays to construct transcript maps that were assembled into transcript atlases.
