Escalante等人表明,一种高度流行的小鼠肠道原生动物,小鼠三毛滴虫,被发现是小鼠结肠炎的一个混杂因素。感染这种寄生虫的小鼠Th 1细胞因子的基线水平升高,并发展为Th 1介导的疾病。哺乳动物的胃肠道内有多种微生物,包括细菌、真菌、原生动物、蠕虫和病毒。通过共同进化,哺乳动物和这些微生物已经发展出一种共生关系,这种共生关系通过宿主对微生物因素的持续感知和耐受性或促炎反应的产生而得以维持。在分析非同窝小鼠品系中T细胞驱动的结肠炎时,我们偶然发现一种非遗传性传播因子显著增加了疾病易感性。我们确定了原生动物鼠三毛滴虫作为疾病恶化的因素。此外,实验定殖T.小鼠在未处理的野生型小鼠盲肠中诱导了Th 1应答升高,并在T细胞转移后加速了Rag 1 −/−小鼠的结肠炎。总的来说,我们描述了一种新的跨王国的相互作用,改变免疫细胞的稳态和疾病的易感性。这个不可预测的微生物引发免疫反应的例子突出了研究跨王国相互作用的重要性,并提醒人们在所有小鼠研究中使用同窝对照的重要性。
Escalante et al. show that a highly prevalent mouse intestinal protozoa, Tritrichomonas muris, was found to be a confounding factor in murine colitis. Mice infected with this parasite had elevated baseline levels of Th1 cytokines and developed exacerbated Th1-mediated disease. The mammalian gastrointestinal tract hosts a diverse community of microbes including bacteria, fungi, protozoa, helminths, and viruses. Through coevolution, mammals and these microbes have developed a symbiosis that is sustained through the host’s continuous sensing of microbial factors and the generation of a tolerant or pro-inflammatory response. While analyzing T cell–driven colitis in nonlittermate mouse strains, we serendipitously identified that a nongenetic transmissible factor dramatically increased disease susceptibility. We identified the protozoan Tritrichomonas muris as the disease-exacerbating element. Furthermore, experimental colonization with T. muris induced an elevated Th1 response in the cecum of naive wild-type mice and accelerated colitis in Rag1−/− mice after T cell transfer. Overall, we describe a novel cross-kingdom interaction within the murine gut that alters immune cell homeostasis and disease susceptibility. This example of unpredicted microbial priming of the immune response highlights the importance of studying trans-kingdom interactions and serves as a stark reminder of the importance of using littermate controls in all mouse research.
