Abstract

Tumors require a constant influx of myelomonocytic cells to support the angiogenesis and stroma remodeling needed for their growth. This is mediated by tumor-derived factors, which cause sustained myelopoiesis and the accumulation and functional differentiation of myelomonocytic cells, most of which are macrophages, at the tumor site. An important side effect of the accumulation and functional differentiation of these cells is that they can induce lymphocyte dysfunction. A complete understanding of the complex interplay between neoplastic and myelomonocytic cells might offer novel targets for therapeutic intervention aimed at depriving tumor cells of important growth support and enhancing the antitumor immune response.

摘要

肿瘤需要持续涌入骨髓单核细胞来支持其生长所需的血管生成和基质重塑。这是由肿瘤衍生因子介导的,这些因子会导致持续的骨髓生成以及骨髓单核细胞在肿瘤部位的积累和功能分化,其中大多数是巨噬细胞。这些细胞积累和功能分化的一个重要副作用是它们会诱导淋巴细胞功能障碍。全面了解肿瘤细胞与骨髓单核细胞之间复杂的相互作用,可能会为治疗干预提供新的靶点,旨在剥夺肿瘤细胞重要的生长支持并增强抗肿瘤免疫反应。
