Macrophages (M) are highly heterogenous and versatile innate immune cells involved in homeostatic and immune responses. Activated M can exist in two extreme phenotypes: pro-inflammatory (M1) M and anti-inflammatory (M2) M. These phenotypes can be recapitulated in vitro by using ligands of toll-like receptors (TLRs) and cytokines such as IFNγ and IL-4. In recent years, human induced pluripotent stem cells (iPSC)-derived M have gained major attention, as they are functionally similar to human monocyte-derived M and are receptive to genome editing. In this study, we polarised iPSC-derived M to M1 or M2 and analysed their proteome and secretome profiles using quantitative proteomics. These comprehensive proteomic data sets provide new insights into functions of polarised M.
巨噬细胞（M）是高度异质性且多功能的固有免疫细胞，参与稳态和免疫反应。活化的M可呈现两种极端表型：促炎性（M1）巨噬细胞和抗炎性（M2）巨噬细胞。通过使用Toll样受体（TLR）配体以及细胞因子如IFNγ和IL-4，可在体外重现这些表型。近年来，人诱导多能干细胞（iPSC）衍生的巨噬细胞备受关注，因为它们在功能上类似于人单核细胞衍生的巨噬细胞，并且易于进行基因组编辑。在本研究中，我们将iPSC衍生的巨噬细胞极化为M1或M2，并使用定量蛋白质组学分析它们的蛋白质组和分泌蛋白质组谱。这些全面的蛋白质组数据集为极化巨噬细胞的功能提供了新见解。
