PTR 232-2019. Mechabiome. Computational imaging of the spatiotemporal distribution of forces in gut tissue: a study of the cross talk between cell mechanics, microbiome and infectious processes
Mechanical forces trigger many cellular functions and change the geometry and physical properties of a tissue. Very few studies look at the biomechanisms of invasion of microbes at tissue level. – In this project […]
Impact of tissue components on cell migration: adhesion strength, cell morpho-dynamics and intracellular biophysics parameters.
We aim to analyze the impact of substrates on Entamoeba histolytica mode of migration during colonic mucosa invasion using live imaging and quantitative image analysis. E. histolytica, the etiological agent of amoebiasis, is a […]
Impact of gut mechanical forces and 3D architecture on the intestine homeostasis during pathogen interaction and in cancer disease
The intestine, and in particular the colon, comprising a mucus blanket, an epithelial monolayer and the lamina propria rich in immune cells, is constantly subjected to shear stress (flow) and peristaltic motion (stretching), both […]
Imaging and mathematical modelling of cell morphology and motility
Elucidating the mechanisms underlying cell deformation and motility is a topic of major interest in cell biology, for they are strongly involved in cell development, immune responses, cancer and infectious diseases. This projects focuses on the […]
