Tumor-associated macrophages (TAMs) provide a significant contribution to tumor growth and metastasis. We demonstrated the existence of two main TAM subsets, differing in activation state and localization. Of these, M2-like TAMs reside in hypoxic regions of the tumor mass and can be used as targets for hypoxia tracers. This said, hypoxia does not regulate the differentiation of TAMs but finely tunes the activity of the M2-like population.
肿瘤相关巨噬细胞(TAM)对肿瘤生长和转移起着重要作用。我们证明了存在两种主要的TAM亚群,它们在激活状态和定位上有所不同。其中,M2样TAM存在于肿瘤块的缺氧区域,可作为缺氧示踪剂的靶点。也就是说,缺氧并不调节TAM的分化,而是精细调节M2样群体的活性。
