Abstract

In this paper, we use a high resolution multimodality label-free flow imaging assay to investigate the effect of platelet shedding of key adheso-signalling receptors in thrombus formation assay by inhibiting activation-induced metalloproteolytic cleavage of platelet receptors (GPIb of the GPIb-IX-V complex and GPVI).

Funding Information:
Using COSI, we unpicks intra-thrombus mass and adhesive platelet-only activity events under fluid shear stress. With a broad range metalloproteinase inhibitor blocking shedding of platelet adhesion receptors, we shown the elevated adhesive platelet activity at average of 42.1 µm/s and minimal change in intra-thrombus mass.
