Evaluation of mTORC1 signaling in mouse atherosclerotic macrophages by flow cytometry and immunofluorescence

Previous studies have demonstrated that a high-protein diet leads to increased atherosclerosis in mice, and that this adverse effect is caused by activation of macrophage mTORC1 signaling. Here, we provide a detailed protocol for the evaluation of diet-induced mTORC1 signaling in plaque macrophages in athero-sclerosis-prone apolipoprotein E (ApoE) knockout (KO) mice. This protocol includes flow cytometry and immunofluorescence analysis of atherosclerotic macrophages that can be used to study the atherogenic potential of a variety of mTORC1 modulators.For complete details on the use and execution of this protocol, please refer to Zhang et al. (2020).
