干细胞衍生的类器官概括了其原始组织的体内生理学,代表了模拟医学疾病如传染病的有价值的系统。隐孢子虫是一种原生动物寄生虫,是腹泻的主要原因,也是全球儿童死亡的主要原因。药物开发需要对隐孢子虫的病理生理学有详细的了解,但由于缺乏最佳的体外培养系统,实验方法受到阻碍。在这里,我们表明隐孢子虫可以感染来自人类小肠和肺的上皮类器官。寄生虫在类器官内繁殖并完成其复杂的生命周期。隐孢子虫类器官感染期间转录组的时间分析揭示了与其生命周期相关的转录物的动态调节。我们的研究提出了类器官作为一个生理相关的体外模型系统,研究隐孢子虫感染。
Stem cell-derived organoids recapitulate in vivo physiology of their original tissues, representing valuable systems to model medical disorders such as infectious diseases. Cryptosporidium, a protozoan parasite, is a leading cause of diarrhea and a major cause of child mortality worldwide. Drug development requires detailed knowledge of the pathophysiology of Cryptosporidium, but experimental approaches have been hindered by the lack of an optimal in vitro culture system. Here we show that Cryptosporidium can infect epithelial organoids derived from human small intestine and lung. The parasite propagates within the organoids and completes its complex life cycle. Temporal analysis of the Cryptosporidium transcriptome during organoid infection reveals dynamic regulation of transcripts related to its life cycle. Our study presents organoids as a physiologically relevant in vitro model system to study Cryptosporidium infection.
