🚨Paper alert! 🚀 We presented SINETRA at #ISBI2025 in Houston A new simulator for generating realistic 2D/3D neuron tracking data in moving animals like Hydra vulgaris 🧠 Helps test and improve tracking algorithms under tough conditions 📄 dx.doi.org/10.1109/ISBI... #celltracking #syntheticdata #ISBI

Exciting news! 🎉 We propose Spatiopath, a null-hypothesis framework for cell-cell & cell-tumor interactions that distinguishes statistically significant immune cell associations from random ones.📊🔬 Check it out:😊 www.nature.com/articles/s41... #statistics #immunology #oncology

👉To classify the dynamic behaviors governing biological particles, we developed a neural network model based on geometric trajectory descriptors and a framework to robustly detect dynamic changes in compound trajectories. #simulation #activationpathwayofreceptorsCCR5 👉 hal.science/hal-04870375v1

The stiffness of cells and their nuclei is a biomarker of several pathologies, yet is usually reduced to a single value. In our last paper, we propose a method to estimate heterogeneous maps of stiffness inside freely moving cells using only fluorescence imaging. ieeexplore.ieee.org/document/107...

Fibronectin induces a transition from amoeboid to a fan morphology and modifies migration in Entamoeba histolytica

Author summary Even though we know increasingly well how cells move in tissues, the question of whether parasites modify their migration as a function of the host tissue environment requires further i...
