Abstract：
The microbiota can impact antitumor immunity, but whether the microbiota regulates omental antitumor immunity remains elusive. In this issue of Cell Host & Microbe, Meza-Perez et al. demonstrated that Proteobacteria consume arginine to increase Treg cell suppressive capacity and inhibit antitumor immune responses, promoting tumor growth in the omentum.
摘要：
微生物群可以影响抗肿瘤免疫，但是微生物群是否调节网膜的抗肿瘤免疫仍然难以捉摸。在本期《细胞宿主和微生物》中，Meza-Perez等人。表明，变形杆菌消耗精氨酸增加Treg细胞抑制能力和抑制抗肿瘤免疫反应，促进网膜中的肿瘤生长。
