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.

微生物群警报：变形菌消耗精氨酸来抑制大网膜抗肿瘤免疫力

微生物群可以影响抗肿瘤免疫，但微生物群是否调节大网膜抗肿瘤免疫仍不清楚。在本期《细胞宿主与微生物》中，Meza-Perez 等人。证明变形菌消耗精氨酸来增加 Treg 细胞抑制能力并抑制抗肿瘤免疫反应，促进大网膜肿瘤生长。
