Major cause of inflammatory bowel disease found 英国科学家找到炎症性肠病的主要病因
英国科学家找到了炎症性肠病（ IBD） 的一个主要病因。科学家们在我们的 DNA 中发现了一个薄弱点， 95% 的患者的 DNA 中都存这个弱点。
Crohn's disease and ulcerative colitis are the most common forms of inflammatory bowel disease. One part of the immune system, called macrophages, is highly implicated.
克罗恩病和溃疡性结肠炎是最常见的炎症性肠病。人体免疫系统中巨噬细胞与病因密切相关。
The researchers at the Francis Crick Institute discovered the macrophages master regulator of inflammation is a section of DNA that controls the whole suite of inflammatory chemicals that the cells release, and some people are born with a version that makes their body respond excessively.
弗朗西斯·克里克研究所的研究人员发现，巨噬细胞作为炎症的主调节器，也是一段脱氧核糖核酸（DNA），该段 DNA 控制着细胞释放的一整套炎症化学物质，而有些人天生就有一种不同的 DNA “版本”，会让身体反应过度。
The researchers use this knowledge to test drugs that are already approved for other conditions. These could calm inflammation in samples of bowel tissue from IBD patients.
研究人员利用这些知识来测试已获批用于治疗其它疾病的药物。这些药物应该可以缓解在炎症性肠病患者肠道组织样本中已发现的炎症。

答案
1. What part of the body is responsible for inflammatory bowel disease?
One part of the immune system, called macrophages, is highly implicated.
2. What part of the body controls the inflammatory chemicals released by cells?
The macrophages master regulator of information is a section of DNA that controls the whole suite of inflammatory chemicals.
3. True or False? Some people are born with a section of DNA that makes their bodies produce more inflammatory chemicals than they need.
True. Some people are born with a version that makes their bodies respond excessively.
4. True or False? Doctors are treating IBD with drugs made for other illnesses.
