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.
