溶组织内阿米巴(痢疾变形虫)能通过咬食和吞掉细胞碎片攻击人类肠道,并在发展中国家引发致命腹泻。4月10日的《自然》杂志报告了它们吞下肠道细胞的过程,或将对治疗溶组织内阿米巴感染提供新目标。溶组织内阿米巴带来的感染会导致严重组织损伤,出现肠道溃疡或脓肿,但人们之前并不清楚溶组织内阿米巴是如何杀死细胞的。曾有人认为溶组织内阿米巴是先杀死细胞再将其吞下的,但美国弗吉尼亚大学的William Petri及研究团队得出了相反结论。他们使用实时显微镜成像,用
Entamoeba histolytica (dysentery amoeba) attacks the human gut by eating and swallowing cell debris and triggering deadly diarrhea in developing countries. The April 10 issue of Nature reports the process of swallowing intestinal cells or will provide new targets for the treatment of Entamoeba histolytica infection. Entamoeba histolytica infection can cause severe tissue damage, intestinal ulcers or abscesses, but it was not clear before how Entamoeba histolytica killed cells. Some people think that Entamoeba histolytica is the first to kill cells and swallow them, but William Petri of the University of Virginia and the research team reached the opposite conclusion. They use real-time microscope imaging with
