占主导地位的TLR5R392X多态性在大约7%的人类中消除了鞭毛蛋白反应。我们报道,依赖tlr5的共生菌通过增加全身IL-6驱动粘膜外部位的恶性进展,IL-6驱动髓源性抑制细胞(MDSCs)的动员。机制上,扩大的粒细胞性MDSCs导致tlr5应答肿瘤中的γδ淋巴细胞分泌半乳糖凝集素-1,抑制抗肿瘤免疫,加速恶性进展。相比之下,IL-17在tlr5无应答的荷瘤小鼠中持续上调,但仅在il -6无应答的肿瘤中加速恶性进展。重要的是,共生菌的消耗消除了肿瘤生长中tlr5依赖性差异。在tlr5应答/无应答的卵巢癌和乳腺癌患者中,炎症细胞因子和恶性进化的对比差异得到了概括。因此,癌症患者的炎症、抗肿瘤免疫和临床转归都受到一种共同的TLR5多态性的影响。
The dominant TLR5R392X polymorphism abrogates flagellin responses in >7% of humans. We report that TLR5-dependent commensal bacteria drive malignant progression at extra-mucosal locations by increasing systemic IL-6, which drives mobilization of myeloid derived suppressor cells (MDSCs). Mechanistically, expanded granulocytic MDSCs cause γδ lymphocytes in TLR5-responsive tumors to secrete galectin-1, dampening anti-tumor immunity and accelerating malignant progression. In contrast, IL-17 is consistently up-regulated in TLR5-unresponsive tumor-bearing mice, but only accelerates malignant progression in IL-6-unresponsive tumors. Importantly, depletion of commensal bacteria abrogates TLR5-dependent differences in tumor growth. Contrasting differences in inflammatory cytokines and malignant evolution are recapitulated in TLR5-responsive/unresponsive ovarian and breast cancer patients. Therefore, inflammation, anti-tumor immunity and the clinical outcome of cancer patients are influenced by a common TLR5 polymorphism.
