Hypoxia confers to macrophages angiogenic and immunosuppressive properties which promote tumor growth and progression. Preventing the migration of macrophages into hypoxic tumor regions hinders angiogenesis and restores the tumor-suppressive properties of these immune cells. We have recently uncovered a neuropilin 1- and semaphorin 3A-dependent signaling pathway that defines the repositioning of macrophages to hypoxic tumor niches, a discovery that generates new options for the development of complementary anticancer treatments.
缺氧赋予巨噬细胞血管生成和免疫抑制特性,从而促进肿瘤生长和进展。阻止巨噬细胞迁移到缺氧的肿瘤区域会阻碍血管生成,并恢复这些免疫细胞的肿瘤抑制特性。我们最近发现了一种依赖神经纤毛蛋白 1 和信号素 3A 的信号通路,该通路定义了巨噬细胞向缺氧肿瘤龛位的重新定位,这一发现为开发互补的抗癌治疗方法提供了新的选择。
