Why the study?
Current understanding of how the structure of GPVI relates to function is inadequate, with recent studies contradicting each other regarding its role as an anti-thrombotic target.

Key result
GPVI dimerization is not required for binding to collagen but facilitates binding through increased avidity, with GPVI expressed as a mixture of monomers and dimers on resting platelets.

GPVI inhibition may reduce thrombosis with less bleeding than DAPT; leaves open confirmation in clinical trials.
This review clarifies the structure-function relationship of the platelet GPVI receptor, suggesting that dimerization is not strictly required for collagen binding but increases avidity, which may inform future anti-thrombotic drug design.
Clark et al. (2021) conducted a review in Coronary artery thrombosis, ischemic stroke, and atherothrombosis. GPVI receptor structure-function was evaluated. GPVI dimerization is not required for binding to collagen but facilitates binding through increased avidity, with GPVI expressed as a mixture of monomers and dimers on resting platelets.
