Effect of Fluid Shear Stress on Endocytosis of Heparan Sulfate and Low-density Lipoproteins. Barkefors, I., Aidun, C. K., & Ulrika Egertsdotter, E. M. *Journal of Biomedicine and Biotechnology*, 2007:1–8, 2007. Paper doi abstract bibtex Hemodynamic stress is a critical factor in the onset of atherosclerosis such that reduced rates of shear stress occurring at regions of high curvature are more prone to disease. The level of shear stress has direct influence on the thickness and integrity of the glycocalyx layer. Here we show that heparan sulfate, the main component of the glycocalyx layer, forms an intact layer only on cell surfaces subjected to shear, and not under static conditions. Furthermore, receptor-mediated endocytosis of heparan sulfate and low-density liporoteins is not detectable in cells exposed to shear stress. The internalized heparan sulfate and low-density lipoproteins are colocalized as shown by confocal imaging.
