In the absence of IL-10, Helicobacter hepaticus (Hh) induces colitis. In this issue of Cell Host & Microbe, Danne et al. (2017) report that Hh produces a polysaccharide that induces an anti-inflammatory response in macrophages, providing a potential clue as to why this bacterium is normally tolerated by the immune system.

甜的！幽门螺杆菌使肠道巨噬细胞平静

在没有IL-10的情况下，肝幽门螺杆菌（Hh）会诱发结肠炎。在本期《细胞宿主与微生物》中，Danne等人。（2017）报告说Hh产生了一种在巨噬细胞中诱导抗炎反应的多糖，为为什么这种细菌通常被免疫系统耐受提供了潜在线索。
