High-content high-resolution microscopy coupled with deep learning-based analysis reveals novel phenotypes at the single-cell level during Shigella infection.
Megakaryocytes form a 3D cage of laminin and collagen IV that stabilizes them within their vascular niche, while β1/β3 integrins and MMP are key regulators that assist megakaryocyte maturation and intravasation.
