Entamoeba histolytica, the causative agent of amoebiasis, is a protozoan parasite characterised by its amoeboid motility, which is essential to its survival and invasion of the human host. Elucidating the molecular mechanisms leading to invasion of human tissues by E. histolytica requires a quantitative understanding of how its cytoskeleton deforms and tailors its mode of migration to the local microenvironment. Here we review the wide range of methods available to extract biophysical information from amoeboid cells, from interventional techniques to computational modelling approaches, and discuss how recent developments in bioimaging and bioimage informatics can complement our understanding of cellular morphodynamics at the intracellular level.
溶组织内阿米巴是阿米巴病的病原体,是一种原生动物寄生虫,其特征在于其阿米巴样运动,这对其在人类宿主中的存活和侵袭至关重要。阐明溶组织内阿米巴侵袭人体组织的分子机制需要定量了解其细胞骨架如何变形以及如何根据局部微环境调整其迁移方式。在这里,我们回顾了从介入技术到计算建模方法等多种可用于从阿米巴样细胞中提取生物物理信息的方法,并讨论了生物成像和生物图像信息学的最新进展如何能补充我们在细胞内水平对细胞形态动力学的理解。
