猪螺杆菌是一种人畜共患感染相关细菌,可诱发人和动物胃粘膜相关淋巴组织(MALT)淋巴瘤。最近,我们报道了猪嗜血杆菌感染后胃M​​ALT淋巴瘤的形成是由干扰素(IFN)-γ激活诱导的。在这里,我们发现,猪嗜血杆菌感染后,Toll 样受体 (TLR) 4–Toll/IL-1 受体结构域包含接头诱导干扰素-β (TRIF) 通路的激活与胃上皮细胞产生 1 型干扰素(IFN-α、IFN-β)相关。此外,这些 1 型 IFN 与胃 B 细胞上的 1 型 IFN 受体相互作用,促进 IFN-γ 的分泌,并且 B 细胞中的正反馈调节可增强 IFN-γ 的激活。这些结果表明,TLR4-TRIF-1 型 IFN-IFN-γ 通路在猪嗜血菌感染后胃 MALT 淋巴瘤的发展中至关重要,因此可能代表预防这种情况的治疗靶点。猪嗜血菌 MPLA 通过 TLR4-TRIF 信号传导导致胃中产生 1 型 IFN B 细胞上 1 型 IFN 和 IFNAR 之间的相互作用导致 IFN-γ 产生 B 细胞上 IFN-γ 和 IFNGR 的相互作用导致 IFN-γ 正反馈调节 胃 B 细胞的 IFN-γ 在猪嗜血杆菌感染后诱导胃淋巴滤泡免疫学;微生物学;癌症
Helicobacter suis, a zoonotic infection-related bacterium, can induce gastric mucosa-associated lymphoid tissue (MALT) lymphoma in humans and animals. Recently, we reported that the formation of gastric MALT lymphoma after H. suis infection is induced by interferon (IFN)-γ activation. Here, we revealed that activation of the Toll-like receptor (TLR) 4–Toll/IL-1 receptor domain-containing adapter-inducing interferon-β (TRIF) pathway after H. suis infection is associated with the production of type 1 IFNs (IFN-α, IFN-β) by gastric epithelial cells. Additionally, these type 1 IFNs interact with type 1 IFN receptors on gastric B cells, facilitating the secretion of IFN-γ and the activation of which is enhanced by positive feedback regulation in B cells. These results suggest that the TLR4–TRIF-type 1 IFN–IFN-γ pathway is crucial in the development of gastric MALT lymphoma after H. suis infection and may, therefore, represent a therapeutic target for the prevention of this condition. H. suis MPLA causes type 1 IFN production in the stomach via TLR4–TRIF signaling The interaction between type 1 IFNs and IFNAR on B cells causes IFN-γ production Interaction of IFN-γ and IFNGR on B cells causes IFN-γ positive feedback regulation IFN-γ from gastric B cells induces gastric lymphoid follicles after H. suis infection Biological sciences; Immunology; Microbiology; Cancer
