Highlights the open question of how Glycoprotein VI activation modulates the platelet cytoskeleton during thrombus formation.
Glycoprotein (GP) VI is the primary signaling receptor for collagen and is found exclusively on platelets and megakaryocytes. GPVI engagement by exposed collagen within a damaged vascular space initiates thrombus formation, and subsequent GPVI interactions with fibrin contribute to thrombus growth and stability [1]. While the GPVI signaling pathway that uses an immunoreceptor tyrosine–based activation motif (ITAM) present within the cytoplasmic tail of the linked FcRγ chain is well characterized [2], how GPVI activation modulates the platelet cytoskeleton remains an open question.
