How do blood vessels adapt to pressure? 🩸
A new collaborative study from the Salbreux lab shows how changes in endothelial cells help vessels stretch and stay strong — thanks to actin fibers and a smart mechanical model.

Interplay of actin nematodynamics and anisotropic tension controls endothelial mechanics - Nature Physics

Blood flow through a vessel deforms vessel walls. Cells lining these walls sense the changes in pressure as blood flows and reorient their actin fibres in the direction of largest tension.
