调节性 T (Treg) 细胞在幽门螺杆菌免疫逃避和持续感染中发挥着关键作用。除了 Treg 细胞外,尚不清楚是否涉及新定义的 B 细胞亚群,即产生白细胞介素 (IL)-10 的 B 细胞。使用H.的小鼠模型。幽门螺杆菌感染后,我们研究了幽门螺杆菌感染后胃肠粘膜、脾脏和肠系膜淋巴结中产生IL-10的B细胞和Foxp3+Treg细胞的动态变化。幽门螺杆菌感染。我们观察到,除了 Foxp3+Treg 细胞外,H 后还可以诱导产生 IL-10 的 B 细胞。幽门螺杆菌感染,并且它们比 Foxp3+Treg 细胞更早扩增。此外,H. 诱导的调节性免疫反应。幽门螺杆菌并不局限于胃粘膜。我们的研究结果可能为进一步研究H.幽门螺杆菌免疫逃避和与幽门螺杆菌相关的疾病。幽门螺杆菌感染。
Regulatory T (Treg) cells play a critical role inHelicobacter pyloriimmune evasion and persistent infection. In addition to Treg cells, it is still unknown whether a newly defined B-cell subset, interleukin (IL)-10-producing B cells, is involved. Using a mouse model ofH. pyloriinfection, we investigated the dynamic changes of IL-10-producing B cells and Foxp3+Treg cells in gastrointestinal mucosa, spleen and mesenteric lymph nodes followingH. pyloriinfection. We observed that in addition to Foxp3+Treg cells, IL-10-producing B cells could also be induced afterH. pyloriinfection and they expanded earlier than Foxp3+Treg cells did. Moreover, the regulatory immune responses induced byH. pyloriwere not limited to gastric mucosa. Our findings may provide new clues for further research onH. pyloriimmune evasion and diseases associated withH. pyloriinfection.
