Core Concepts
PhagoStat offers a scalable framework for quantifying cell phagocytosis in neurodegenerative diseases, providing insights into microglial behavior and disease progression.
Abstract
PhagoStat introduces an end-to-end framework for quantifying and analyzing phagocytic activity in neurodegenerative diseases. The pipeline processes large datasets efficiently, ensuring data quality verification and explainable cell segmentation. By incorporating interpretable deep learning capabilities, PhagoStat optimizes architecture design and execution time. The method has been validated on public benchmarks, showcasing state-of-the-art performance in quantifying microglial cell phagocytosis. The release of an open-source pipeline and dataset aims to advance research in neurodegenerative diseases by promoting the development of efficient algorithms dedicated to immune system characterization.
The latest advances in physics have revolutionized high-throughput microscopy, enabling automated analysis of cellular dynamics. Phagocytosis, particularly by microglial cells, plays a crucial role in neurodegenerative diseases' pathogenesis. Innovative approaches utilizing computer vision and deep learning are essential for accurate quantification of cell interactions and behaviors. DL-based models like U-Net offer advanced segmentation techniques but lack interpretability crucial for clinical adoption. Interpretable DL tools can enhance adoption rates and drive further discoveries in the field.
PhagoStat's pipeline streamlines data loading, normalization, registration, noise detection, aggregate quantification, cellular segmentation, and statistical reporting. By leveraging HPC clusters, the framework processes vast datasets swiftly with CPU power alone. Transparency is ensured through accessible intermediate results aligned with GDPR guidelines. The methodology empowers experts to gain deeper insights into studied processes while optimizing model training efficiency.
