Project description:While aging is well established as an important risk factor for the development and progression of atherosclerosis, the underlying molecular mechanisms of this relationship remain poorly defined, and its role in atherosclerosis regression is unknown. We investigated the response of bone marrow-derived macrophages isolated from old and young mice to atherogenic aggregated LDL.
Project description:Bone marrow macrophages were isolated from CD40-TRAF2/3/5 -/- and CD40-TRAF6 -/- mice, followed by induction of differentiation and maturation. Apoptotic cardiomyocytes were then added to trigger efferocytosis for 3 hours. Subsequently, total proteins were extracted for proteomic sequencing.
Project description:Bone marrow cells (BM) were isolated and primed with M-CSF (M BMDM) or GM-CSF (GM BMDM) for 7 days. M-BMDMs were treated with IL6 (20 ng/ml) for 3 h or 24 h while GM-BMDMs were treated for 3 h. The difference between BM, M-BMDM, and GM-BMDM were analyzed to describe the phenotye and function of each population. Moreover, by RNA-seq analysis, the influence of IL6 treatment on GM-BMDMs and M-BMDMs were analyzed.
